Description

The present invention relates to an automatic sericulture system, an automatic sericulture method, a program and a storage medium.

Silk moth breeding containers for breeding silk moths are known. Silk moths and food are stored in the silk moth breeding container. The silk moths in the silk moth breeding container grow by feeding on the food in the silk moth breeding container.

When breeding silk moths, it is generally necessary to supply food such as mulberry leaves to the silk moth breeding container every day (excluding the sleep period of silk moths). The larval stage of the silk moth is about 25 days, and molting is performed four times during the larval stage. Then, at the 5th instar of the final age, the silk moth synthesizes silk protein in the body, spits a thread of about 1200 m, and makes a cocoon by the thread.

As a related technique, Patent Document 1 describes a sericulture method. In the sericulture method described in Patent Document 1, a sheet-shaped sericulture feed is laid on a flat pallet, and a net is arranged on the sheet-shaped sericulture feed. The net is used to grab the silk moth as it molts.

Attempts to save labor in sericulture have been introduced. Patent Document 2 describes a method of breeding silk moths using artificial feed, which is performed by transshipping breeding trays stacked in multiple stages and moving a breeding net for breeding silk moths on an arm portion. The method of raising silk moths is described to simplify the above. Further, according to Patent Document 1, when breeding silk moths in a sterile room, the work process can be simplified to reduce the invasion of germs from the outside and the influence of fallen germs in the room. Are listed.

In Patent Document 3, in order to save labor when breeding a large number of silk moths, the breeding cages 10 housed in a plurality of breeding shelves are circulated and moved by a drive facility or automatically transported to a work port. The silk moth breeding equipment is described.

However, in Patent Document 1, most of the breeding of silk moths is carried out manually. Therefore, the cost required for breeding silk moths is high. In addition, since most of the silk moth breeding is done manually, there is a relatively high risk of contamination of the silk moth breeding environment with germs.

Further, in the silk moth breeding method described in Patent Document 2, an arm can be used for transshipment of a breeding tray containing artificial feed and movement of a breeding net, but feed supply and installation of a sericulture device can be automated. It does not automate all the processes of silk moth raising.

In the silk moth breeding device described in Patent Document 3, the breeding cage 10 is circulated and moved by a drive facility or automatically transported to a work port. However, the plastic bag is attached and detached, and the breeding cage is replaced. Etc. cannot be automated, and not all processes of sericulture are automated.

An object of the present invention is to provide an automatic sericulture system capable of breeding silk moths in an aseptic state and automating all processes of sericulture.

The object of the present invention described above is
Egg supply means that automatically supplies eggs to group breeding containers,
Feed supply means that automatically supplies feed to group breeding containers,
A means of moving silk moths that automatically moves silk moths from a group breeding container to an individual breeding container,
A cocoon removal method that automatically removes cocoons from individual breeding containers,
Collective breeding containers and / or individual breeding containers are automatically stored in the breeding shelves, and the breeding container automatic storage means that are automatically taken out from the breeding shelves, and
A breeding container moving means for automatically moving a group breeding container and / or an individual breeding container between the above means.
It is achieved by an automatic sericulture system characterized by being equipped with.

According to the automatic sericulture system according to the present invention, it is possible to provide an automatic sericulture system capable of breeding silk moths in a sterile state and automating all processes of sericulture.

[First Embodiment]
The silk moth breeding system 1A and the silk moth breeding method according to the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram schematically showing a silk moth breeding system 1A in the first embodiment. FIG. 2 is a flowchart showing an example of the silk moth breeding method in the first embodiment.

The silk moth breeding system 1A according to the first embodiment includes a silk moth transfer device 10 for transferring silk moths from a first breeding container C1 to a second breeding container C2, and a second breeding container transport device for transporting a second breeding container C2. 20 and.

It is preferable that a plurality of silk moths A are group-reared inside the first breeding container C1. In other words, the first breeding container C1 is preferably a group breeding container for group breeding a plurality of silk moths in the breeding room. In the first breeding container C1, for example, 10 or more and 1000 or less, 30 or more and 500 or less, or 50 or more and 300 or less silk moths are group-reared. Area of the breeding area in one of the first rearing container C1 (area in planar view), for example, 100 cm ² or more 10000 cm ² or less, 400 cm ² or more 4900Cm ² or less, is 900 cm ² or more 2500 cm ² or less. The first breeding container C1 is, for example, a container whose upper surface is open.

It is preferable that a plurality of silk moths A are individually bred inside the second breeding container C2. In other words, the second breeding container C2 is preferably an individual breeding container for individually breeding one silk moth in each breeding room. In the example described in FIG. 1, the second breeding container C2 includes a plurality of breeding chambers SP isolated from each other. In the example described in FIG. 1, the second breeding container C2 includes the first breeding room SP1 and the second breeding room SP2, and the first breeding room SP1 and the second breeding room SP2 are isolated from each other. The number of breeding room SPs included in the second breeding container C2 is, for example, 10 or more, 30 or more, or 50 or more.

Each breeding room SP may be defined by a separate tubular container or may be defined by a partition wall arranged within the housing member (eg, within the container or frame). In other words, the second breeding container C2 may be an aggregate of a plurality of tubular containers, or may have a plurality of partition walls arranged inside a housing member that defines an outer wall.

The silk moth transfer device 10 transfers the silk moth A from the first breeding container C1 to the second breeding container C2.

In the example described in FIG. 1, the silk moth transfer device 10 accommodates only one silk moth A in each breeding room SP (for example, only one silk moth is housed in the first breeding room SP1). The silk moth A is transferred from the first breeding container C1 to the second breeding container C2 (so that only one silk moth is accommodated in the second breeding room SP2).

The silk moth transfer device 10 includes, for example, a silk moth holding member 11 and a holding member moving device 12 for moving the silk moth holding member 11 from the first breeding container C1 to the second breeding container C2. The silk moth transfer device 10 may include a camera 13 capable of photographing the silk moth.

The silk moth holding member 11 is a member capable of holding a silk moth. The silk moth holding member 11 may include a first grip portion 11a and a second grip portion 11b. In this case, the silk moth holding member 11 can grip one silk moth by reducing the distance between the first grip portion 11a and the second grip portion 11b. Alternatively or additionally, the silk moth holding member 11 may include a vacuum suction portion 11c capable of sucking the skin of the silk moth.

The holding member moving device 12 is, for example, a device capable of three-dimensionally changing the position of the silk moth holding member 11. The holding member moving device 12 is, for example, a robot arm.

The camera 13 images a plurality of silk moths A in the first breeding container C1 based on a control command from the control device 30. The image data acquired by the camera 13 is transmitted to the control device 30 by wire or wirelessly. The control device 30 determines the position and orientation of each of the plurality of silk moths based on the image data. The control device 30 controls the holding member moving device 12 and the silk moth holding member 11 based on the determination result. The silk moth holding member 11 controlled by the control device 30 holds one silk moth. After that, the control device 30 controls the holding member moving device 12 to move the silk moth holding member 11 toward the breeding room SP (for example, the first breeding room SP1) of the second breeding container C2. The control device 30 controls the silk moth holding member 11 to release the holding of the silk moth by the silk moth holding member 11. As a result, the silk moth is housed in one of the second breeding container C2, the breeding room SP (for example, the first breeding room SP1).

The operation of transferring the silk moth in the first breeding container C1 to the breeding room SP of one of the second breeding container C2 is repeatedly executed. For example, after one silk moth is housed in the first breeding room SP1, the camera 13 re-images a plurality of silk moths in the first breeding container C1 based on a control command from the control device 30. The image data acquired by the camera 13 is transmitted to the control device 30. The control device 30 determines the position and orientation of each of the plurality of silk moths based on the image data. The control device 30 controls the holding member moving device 12 and the silk moth holding member 11 based on the determination result. The silk moth holding member 11 controlled by the control device 30 holds one silk moth. After that, the control device 30 controls the holding member moving device 12 to move the silk moth holding member 11 toward the breeding room SP (for example, the second breeding room SP2) of the second breeding container C2. The control device 30 controls the silk moth holding member 11 to release the holding of the silk moth by the silk moth holding member 11. As a result, the silk moth is housed in one of the second breeding container C2, the breeding room SP (for example, the second breeding room SP2).

The second breeding container transport device 20 moves the second breeding container C2 from the silk moth transfer area AR to the second breeding container storage area AR2. The silk moth transfer area AR is an area in which the silk moth A is transferred from the first breeding container C1 to the second breeding container C2. On the other hand, the second breeding container storage area AR2 is an area in which the second breeding container C2 is stored. In the example described in FIG. 1, the shelf T2 is arranged in the second breeding container storage area AR2, and the second breeding container C2 is stored in the shelf T2.

In the example described in FIG. 1, the shelf T2 is a fixed shelf installed in the second breeding container storage area AR2. Further, the second breeding container transport device 20 transports the second breeding container C2 between the silk moth transfer area AR and the second breeding container storage area AR2. Alternatively, the second breeding container transport device 20 may transport the shelf T2 on which the second breeding container C2 is placed between the silk moth transfer area AR and the second breeding container storage area AR2. In other words, the shelf T2 may be a moving shelf.

When the second breeding container C2 is in the second breeding container storage area AR2, the silk moths in the second breeding container C2 feed on the food F and grow.

The second breeding container transport device 20 may include a conveyor such as a belt conveyor and a roller conveyor. Alternatively or additionally, the second breeding container transport device 20 may include a transport device with a transfer device (eg, a stacker crane) for transferring the second breeding container C2 to the shelf T2. .. The second breeding container transport device 20 stores the second breeding container C2 in a predetermined storage position (storage in an empty state among a plurality of storage positions) in the second breeding container storage area AR2 based on a command from the control device 30. Position). The second breeding container transport device 20 is driven by, for example, a motor.

The control device 30 controls the operation of the silk moth transfer device 10 and / or the second breeding container transport device 20. The number of computers included in the control device 30 may be one or a plurality of computers. In other words, one computer may function as the control device 30, or a plurality of computers may function as the control device 30 by coordinating a plurality of computers.

The silk moth breeding system 1 in the first embodiment includes a silk moth transfer device 10 and a second breeding container transport device 20. Therefore, the transfer of the silk moth from the first breeding container C1 to the second breeding container C2 and the movement of the second breeding container C2 to which the silk moth has been transferred can be automated. As a result, the breeding of silk moths is streamlined. Further, since the transfer of the silk moth and the movement of the second breeding container C2 are not performed manually, germs are not substantially mixed in the breeding environment of the silk moth.

In the first embodiment, the silk moth breeding system 1A may include a first breeding container transport device 40 for transporting the first breeding container C1 from the first breeding container storage area AR1 to the silk moth transfer area AR. The first breeding container transport device 40 is preferably a transport device different from the second breeding container transport device 20. The first breeding container transport device 40 includes, for example, a conveyor such as a belt conveyor and a roller conveyor. The first breeding container transport device 40 may include a transport device with a transfer device for transferring the first breeding container C1 to the shelf T1. The first breeding container transport device 40 is driven by, for example, a motor.

When the silk moth breeding system 1A includes the first breeding container transport device 40, the movement of the first breeding container C1 to the silk moth transfer area AR can be automated. As a result, the breeding of silk moths becomes more efficient. Further, since the first breeding container C1 is not moved manually, various germs are not substantially mixed in the breeding environment of the silk moth.

In the example described in FIG. 1, the shelf T1 is arranged in the first breeding container storage area AR1, and the first breeding container C1 is stored in the shelf T1. When the first breeding container C1 is in the first breeding container storage area AR1, the silk moths in the first breeding container C1 feed and grow.

In the first embodiment, the first breeding container storage area AR1 is preferably arranged in a sterile atmosphere AT. Further, the second breeding container storage area AR2 is preferably arranged in a sterile atmosphere AT. Similarly, the silk moth transfer region AR is preferably located in a sterile atmosphere AT. In the present specification, the sterile atmosphere AT means an atmosphere in a space substantially isolated from the outside, and is set so that the abundance of microorganisms is smaller than that in the outside. The cleanliness in the aseptic atmosphere AT is based on the ISO standard (ISO1464-1: 2015), for example, the cleanliness from Class 6 to Class 8, more preferably the cleanliness of Class 7 or less. The cleanliness of Class 6 is the cleanliness equivalent to class 1000 of the US federal standard FED-STD 209E, and the cleanliness of Class 7 is the cleanliness equivalent to class 10000 of the US federal standard FED-STD 209E. The cleanliness is equivalent to class 100,000 of the US federal standard FED-STD 209E.

(How to raise silk moths)
Subsequently, an example of the silk moth breeding method in the first embodiment will be described.

In the first step ST1, a plurality of silk moths are bred in the first breeding container C1. The first step ST1 is the first silk moth breeding step. In the first silk moth breeding step, for example, a plurality of silk moths A are group-reared in the first breeding container C1.

In the second step ST2, a plurality of silk moths in the first breeding container C1 are transferred to the second breeding container C2. The transfer is performed using the silk moth transfer device 10.

The second step ST2 includes a first transport step of transporting the first breeding container C1 to the silk moth transfer area AR, a second transport step of transporting the second breeding container C2 to the silk moth transfer region AR, and a silk moth transfer device. 10 may be used to have a transfer step of transferring a plurality of silk moths A from the first breeding container C1 to the second breeding container C2.

The first transport step is performed using, for example, the first breeding container transport device 40. The second transport step is performed using, for example, the second breeding container transport device 20. The second transfer step may be executed before the first transfer step, may be executed after the first transfer step, or may be executed at the same time as the first transfer step.

In the example described in FIG. 1, the second breeding container C2 includes a plurality of breeding chambers SP for individual breeding. In this case, the second step ST2 (silk moth transfer step) may include transferring a plurality of silk moths A bred in the first breeding container C1 to a plurality of breeding room SPs, respectively. In the example described in FIG. 1, the silk moth transfer device 10 transfers a plurality of silk moths A group-reared in the first breeding container C1 to a plurality of breeding room SPs for individual breeding. Therefore, it is possible to smoothly switch from group breeding to individual breeding without mixing germs into the silk moth breeding environment. The silk moth transfer step (that is, the silk moth transfer step of transferring the silk moth A from the first breeding container C1 to the second breeding container C2) performed by the silk moth transfer device 10 is performed in the first breeding container C1. It may include transferring the silk moth to the food support PL (see FIG. 14) in the second breeding container C2. Alternatively, the silk moth transfer step (that is, the silk moth transfer step of transferring the silk moth A from the first breeding container C1 to the second breeding container C2) performed by the silk moth transfer device 10 is the first breeding container C1. The silk moth inside is transferred to the food support PL (see FIG. 5) outside the second breeding container C2, and the feed support PL on which the silk moth A is supported is inserted into the second breeding container C2. It may include things.

After the execution of the second step ST2, the second breeding container C2 to which the plurality of silk moths A have been transferred is transported from the silk moth transfer area AR to the second breeding container storage area AR2. The transfer is carried out using, for example, the second breeding container transfer device 20.

In the third step ST3, a plurality of silk moths A are bred in the second breeding container C2. The third step ST3 is the second silk moth breeding step. In the second silk moth breeding step, for example, each of the plurality of silk moths A is individually bred in an independent breeding room SP.

In the silk moth breeding method of the first embodiment, the silk moth is transferred from the first breeding container C1 to the second breeding container C2 by the silk moth transfer device 10. Therefore, the transfer of silk moths from the first breeding container C1 to the second breeding container C2 can be automated. As a result, the breeding of silk moths is streamlined. Further, since the silk moth is transferred by the silk moth transfer device 10, germs are not substantially mixed in the breeding environment of the silk moth.

Further, in the first embodiment, when a plurality of silk moths A are collectively bred in the first breeding container C1 and each of the plurality of silk moths A is individually bred in the second breeding container C2, the day Small-aged silk moths can be efficiently group-bred in a small space, and large-day silk moths can be individually bred in a state where stress is suppressed. Therefore, in the first embodiment, it is possible to save space for breeding silk moths, improve the efficiency of breeding silk moths, and suppress stress on silk moths. Furthermore, when cocoons are formed on silk moths in a breeding room for individual breeding, the location where the cocoons are formed can be localized. In this case, the cocoon can be easily collected (for example, the cocoon can be collected by a robot).

[Second Embodiment]
The silk moth breeding system 1B and the silk moth breeding method according to the second embodiment will be described with reference to FIGS. 3 to 16. FIG. 3 is a diagram schematically showing the silk moth breeding system 1B in the second embodiment (a schematic plan view schematically showing the inside of the container 2).

FIG. 14 is a schematic perspective view schematically showing an example of the second breeding container C2. FIG. 15 is a schematic perspective view schematically showing an example of the second breeding container C2. FIG. 16 is a flowchart showing an example of the silk moth breeding method in the second embodiment.

The silk moth breeding system 1B in the second embodiment includes a container 2 in which at least one of a plurality of devices constituting the silk moth breeding system 1B is arranged. In the second embodiment, the points different from those in the first embodiment will be mainly described, and the repetitive description of the matters explained in the first embodiment will be omitted. Therefore, it goes without saying that the matters explained in the first embodiment can be applied to the second embodiment even if the explanation is not explicitly given in the second embodiment. This also applies to other embodiments.

The silk moth breeding system 1B includes, for example, at least one of a silk moth transfer device 10, a first breeding container transport device 40, a second breeding container transport device 20, and a control device 30. Since the silk moth transfer device 10, the first breeding container transport device 40, the second breeding container transport device 20, and the control device 30 have already been described in the first embodiment, the description of these components will be repeated. Is omitted.

In the example described in FIG. 3, the silk moth breeding system 1B includes two containers 2 (more specifically, a first container 2A and a second container 2B). However, the number of containers 2 included in the silk moth breeding system 1B may be one or three or more.

In the example described in FIG. 3, the second breeding container transport device 20 is arranged in the container 2 (more specifically, the second container 2B). The container 2 can define a substantially closed space (more specifically, a sterile atmosphere AT). Therefore, when the second breeding container transport device 20 is arranged in the container 2, germs are unlikely to be mixed in the transport path of the second breeding container C2.

When the transport device is installed in a closed space, the transport device is generally installed in a building that defines a closed space. On the other hand, in the second embodiment, a transport device such as the second breeding container transport device 20 is arranged in the container 2. The container 2 can define a substantially closed space even when it is arranged outdoors. Therefore, it is not necessary to construct a new building for arranging the transport device. Further, even when the container 2 is arranged in an existing building, the existing building is not required to have a high degree of airtightness because the container 2 defines a substantially closed space. Further, since the container 2 can be transported by a vehicle, a ship, or the like, the degree of freedom in arranging the container 2 is high. It is also easy to move a container once placed in a predetermined place to another place.

Container 2 is, for example, a portable container standardized by ISO 668 (for example, ISO 668: 1995, ISO 668: 2005, ISO 668: 2013, etc.). The container 2 is, for example, a 45-foot container (ISO668 "1EEE" container, "1EE" container, etc.), a 40-foot container (ISO668 "1AAA" container, "1AA" container, "1A" container, "1AX" container, etc. ), 30-foot container (ISO668 "1BBB" container, "1BB" container, "1B" container, "1BX" container, etc.), 20-foot container (ISO668 "1CC" container, "1C" container, "1CX" container Etc.), 10-foot container (ISO668 "1D" container, "1DX" container, etc.), 6.5-foot container (ISO668 "1E" container, etc.), 5-foot container (ISO668 "1F" container, etc.). .. Hereinafter, in the present specification, the portable container standardized by ISO 668 is referred to as "ISO container".

(1st container 2A)
In the example described in FIG. 1, the silk moth breeding system 1B has a first container 2A. The first container 2A is, for example, an ISO container. The length of the first container 2A is, for example, 45 feet, 40 feet, 30 feet, 20 feet, 10 feet, 6.5 feet, or 5 feet.

In the example described in FIG. 1, the first container 2A has a first breeding container storage area AR1. In the example described in FIG. 1, the heat insulating material 91 is arranged along the inner surface Ws of the outer wall Wa of the first container 2A. Further, in the first container 2A, an air conditioner 92 for adjusting the temperature in the first container 2A is arranged.

When the silk moth breeding system 1B includes a first container 2A having a first breeding container storage area AR1, a heat insulating material 91, and an air conditioner 92, the silk moth breeding environment in the first breeding container C1 is a suitable environment. It is possible to set to. The air conditioner 92 may be an air conditioner whose temperature can be adjusted, or may be an air conditioner whose temperature and humidity can be adjusted. The temperature of the first breeding container storage area AR1 is maintained by, for example, 20 degrees Celsius or more and 35 degrees Celsius or less, or 25 degrees Celsius or more and 30 degrees Celsius or less by the air conditioner 92.

When the air conditioner 92 is activated, the pressure inside the first container 2A is set to be higher than the pressure outside the first container 2A. The pressure difference between the pressure inside the first container 2A and the pressure outside the first container 2A is, for example, 10 Pa (Pascal) or more, 100 Pa or more, 1000 Pa or more, 3000 Pa or more, or 5000 Pa or more. By setting the pressure inside the first container 2A to be higher than the pressure outside the first container 2A, the risk of germs being mixed into the first container 2A is reduced.

When the air conditioner 92 is activated, it is preferable that the pressure in the first breeding container storage area AR1 is set to be higher than the pressure in the region outside the first breeding container storage area AR1 in the first container 2A. .. The pressure difference between the two regions is, for example, 10 Pa (Pascal) or more, 100 Pa or more, and 1000 Pa or more. Since the pressure inside the first breeding container storage area AR1 is set to be higher than the pressure in the area outside the first breeding container storage area AR1, germs are mixed into the first breeding container storage area AR1. Risk is reduced. In order to make the pressure inside the first breeding container storage area AR1 higher than the pressure in the area outside the first breeding container storage area AR1, the air supply port 92a of the air conditioner 92 is arranged in the first breeding container storage area AR1. It may have been done.

The air conditioner 92 includes a fan 921 that supplies air from outside the first container 2A into the first container 2A, a heat exchanger 922 that raises or lowers the temperature of the air, and a filter 923 that removes germs from the air. For example, a HEPA filter) is provided.

The air conditioner 92 may include a circulation flow path for circulating the air in the first container 2A in the first container 2A, and a filter 924 (for example, a HEPA filter) arranged in the circulation flow path. When the air conditioner 92 includes a circulation flow path and a filter 924, germs that have invaded the first container 2A are removed by the filter 924.

In the example described in FIG. 3, the silk moth breeding system 1B has a second container 2B. The second container 2B is, for example, an ISO container. The length of the second container 2B is, for example, 45 feet, 40 feet, 30 feet, 20 feet, 10 feet, 6.5 feet, or 5 feet.

In the example described in FIG. 3, the second container 2B has a second breeding container storage area AR2. In the example described in FIG. 3, the heat insulating material 91 is arranged along the inner surface Ws of the outer wall Wa of the second container 2B. Further, in the second container 2B, an air conditioner 92 for adjusting the temperature in the second container 2B is arranged. The air conditioner 92 arranged in the second container 2B is the same air conditioner as the air conditioner 92 arranged in the first container 2A. The air conditioner 92 arranged in the second container 2B includes a fan 921, a heat exchanger 922, a filter (923, 924), and the like, similarly to the air conditioner 92 arranged in the first container 2A. The temperature of the second breeding container storage area AR2 is maintained by, for example, 20 degrees Celsius or more and 35 degrees Celsius or less, or 25 degrees Celsius or more and 30 degrees Celsius or less by the air conditioner 92.

When the air conditioner 92 is activated, the pressure inside the second container 2B is set to be higher than the pressure outside the second container 2B. The pressure difference between the pressure inside the second container 2B and the pressure outside the second container 2B is, for example, 10 Pa (Pascal) or more, 100 Pa or more, 1000 Pa or more, 3000 Pa or more, or 5000 Pa or more.

When the air conditioner 92 is activated, it is preferable that the pressure inside the second breeding container storage area AR2 is set to be higher than the pressure inside the second breeding container storage area AR2 outside the second breeding container storage area AR2. .. The pressure difference between the two regions is, for example, 10 Pa (Pascal) or more, 100 Pa or more, and 1000 Pa or more. In order to make the pressure inside the second breeding container storage area AR2 higher than the pressure in the area outside the second breeding container storage area AR2, the air supply port 92a of the air conditioner 92 is arranged in the second breeding container storage area AR2. It may have been done.

In the example described in FIG. 3, the silk moth breeding system 1B has a first container 2A having a first breeding container storage area AR1 and a second container 2B having a second breeding container storage area AR2. Further, the second container 2B is a container different from the first container 2A. In this case, the silk moth breeding system 1B has a breeding environment for breeding silk moths with a relatively small age (first container 2A) and a breeding environment for breeding silk moths with a relatively large age (second container). It is possible to set the container 2B) independently. For example, for silk moths that are relatively young, it is possible to breed a large number of silk moths in a relatively small space by group breeding. On the other hand, for silk moths that are relatively old, it is possible to reduce the stress acting on the silk moths by raising them individually.

For silk moths that are relatively old, a relatively large breeding space is required. Therefore, the size of the second container 2B having the second breeding container storage area AR2 may be larger than the size of the first container 2A having the first breeding container storage area AR1. Alternatively or additionally, the number of the second containers 2B having the second breeding container storage area AR2 is larger than the number of the first containers 2A having the first breeding container storage area AR1. Container 2 may be arranged. For example, one first container 2A and two or more second containers 2B may be connected. The number of the second container 2B connected to the first container 2A may be 3 or more, 5 or more, or 10 or more.

(Container connecting part 95)
In the example described in FIG. 3, the silk moth breeding system 1B includes a container connecting portion 95 that connects the first container 2A and the second container 2B. The presence of the container connecting portion 95 suppresses the invasion of germs into the first container 2A or the second container 2B. More specifically, when transporting the first breeding container C1, the second breeding container C2, etc. between the first container 2A and the second container 2B, the opening of the first container 2A or the second container 2B There is a risk of germs invading through the opening of the container. In the example described in FIG. 3, since the first container 2A and the second container 2B are connected by the container connecting portion 95 (more specifically, the opening of the first container 2A and the opening of the second container 2B). Since the portions are covered by the container connecting portion 95), the risk of germs invading through these openings is reduced. The container connecting portion 95 may be made of a flexible member made of synthetic resin such as vinyl, may be made of a rigid member such as a metal plate, or may be made of a combination of the flexible member and the rigid member. It may have been done.

In the example described in FIG. 3, the first door DR1 is arranged in the opening of the first container 2A, and the second door DR2 is arranged in the opening of the second container 2B. However, the first door DR1 and / or the second door DR2 may be omitted.

(Feed supply device 60)
In the example described in FIG. 3, the silk moth breeding system 1B includes a food supply device 60. The food supply device 60 is a device that supplies food (silk moth food) to the first breeding container C1 or the second breeding container C2. When the silk moth breeding system 1B includes the feed supply device 60, the supply of food to the first breeding container C1 or the second breeding container C2 can be automated. In this case, when feeding the silk moth, it is possible to prevent germs from being mixed into the breeding environment of the silk moth.

In the example described in FIG. 3, the food supply device 60 is arranged in the first container 2A. Alternatively or additionally, the food supply device 60 may be located in the second container 2B. When the food supply device 60 is arranged in the container 2, it is more effectively suppressed that various germs are mixed into the breeding environment of the silk moth when the food is supplied. However, when the silk moth breeding system 1B does not have the above-mentioned container 2, the food supply device 60 may be arranged at an arbitrary place different from the container 2.

An example of the food supply device 60 will be described with reference to FIG. The food supply device 60 includes, for example, a food storage container 61, a nozzle member 62, a moving device 63, a food supply pipe 64, and a food supply pump 65.

The food storage container 61 is a container for temporarily storing silk moth food. For example, mulberry F1 (more specifically, mulberry leaf powder), okara F2, and water are put into the food storage container 61. In the example described in FIG. 5, the mulberry F1 is charged from the mulberry container into the food storage container 61, and the okara F2 is charged from the okara container into the food storage container 61. The feeding may be done automatically by the mulberry feeding device and / or the okara feeding device, or may be done manually.

In the example shown in FIG. 5, the water supply pipe 67 is connected to the food storage container 61. Then, the water supply to the food storage container 61 is automatically executed by using the water supply pipe 67. In the example shown in FIG. 5, the on-off valve 671 and the filter 672 are arranged in the water supply pipe 67. The on-off valve 671 and the control device 30 are connected by wire or wirelessly so as to be able to transmit signals, and the on-off valve 671 is opened and closed based on a command from the control device 30. When the on-off valve 671 is in the open state, water is supplied to the food storage container 61, and when the on-off valve is in the closed state, water is not supplied to the food storage container 61. The filter 672 removes foreign matter or germs from the water.

In the example shown in FIG. 5, the mulberry, bean curd refuse, and water charged into the food storage container 61 are agitated in the food storage container 61. The stirring is performed by the stirring device 611 driven by the motor M1. The motor M1 and the control device 30 are connected by wire or wirelessly so as to be able to transmit signals, and the motor M1 is driven based on a command from the control device 30. When the motor M1 is driven, the stirrer 611 stirs the mixed feed containing mulberry, okara, and water.

The mixed feed containing mulberry, okara, and water (more specifically, kneaded feed) is supplied from the feed storage container 61 toward the nozzle member 62 by the feed supply pump 65. In the example described in FIG. 5, the bait feed pump 65 may include a screw conveyor or a snake pump. In the example described in FIG. 5, the bait supply pump 65 includes a motor M2 and a rotary shaft 651 driven by the motor M2. The bait supply pump 65 may include a vane member 652 attached to the rotary shaft 651. Alternatively or additionally, the rotary shaft 651 may be a non-linear rotary shaft (eg, a spiral rotary shaft). In this case, the blade member 652 may be omitted.

The motor M2 and the control device 30 are connected by wire or wirelessly so as to be able to transmit signals, and the motor M2 is driven based on a command from the control device 30. When the motor M2 is driven, the rotating shaft 651 rotates. As a result, the rotary shaft 651 or the blade member 652 attached to the rotary shaft 651 pushes the bait (bait) from the upstream side of the bait supply pump 65 toward the downstream side of the bait supply pump 65. In the example shown in FIG. 5, the discharge port of the food storage container 61 and the upstream side of the food supply pump 65 are connected. Then, the bait (bait) discharged from the discharge port of the bait storage container 61 is supplied to the upstream side of the bait supply pump 65. Further, in the example shown in FIG. 5, the bait discharged from the bait supply pump 65 is supplied to the nozzle member 62 via the bait supply pipe 64.

The food supply pipe 64 may be a rigid tube, a flexible tube, or a rigid tube in part and a flexible tube in another part.

In the example described in FIG. 5, the food supply pipe 64 is a pipe that connects the food storage container 61 and the nozzle member 62. The food supply pump 65 described above is arranged in the middle of the food supply pipe 64.

In the example shown in FIG. 5, an on-off valve 641 is arranged in the food supply pipe 64. The on-off valve 641 and the control device 30 are connected by wire or wirelessly so as to be able to transmit signals, and the on-off valve 641 is opened and closed based on a command from the control device 30. When the on-off valve 641 is in the open state, the bait is supplied to the nozzle member 62-1, and when the on-off valve 641 is in the closed state, the bait is not supplied to the nozzle member 62-1.

In the example described in FIG. 5, the food supply pipe 64 includes a main pipe 64 m and a first branch pipe 64d. The on-off valve 641 described above is arranged in the first branch pipe 64d, and the first branch pipe 64d is connected to the nozzle member 62-1 described above.

The food supply pipe 64 may include a second branch pipe 64e. In the example shown in FIG. 5, an on-off valve 643 is arranged in the second branch pipe 64e, and the second branch pipe 64e is connected to the second nozzle member 62-2. The on-off valve 643 and the control device 30 are connected by wire or wirelessly so as to be able to transmit signals, and the on-off valve 643 is opened and closed based on a command from the control device 30.

In the example shown in FIG. 5, the main pipe 64m and the first branch pipe 64d are connected via the branch portion D1. Further, in the example shown in FIG. 5, the main pipe 64m and the second branch pipe 64e are connected via the branch portion D2.

In the example shown in FIG. 5, the food supply pipe 64 includes a return pipe 64r. When the food supply pipe 64 includes the return pipe 64r, the surplus food that is not supplied to the nozzle member 62 among the foods flowing through the main pipe 64m is returned to the food storage container 61 via the return pipe 64r. In the example described in FIG. 5, the portion of the food supply pipe 64 between the branch portion D1 and the food storage container 61 constitutes the return pipe 64r. An on-off valve 645 may be arranged in the return pipe 64r.

The nozzle member 62 (nozzle member 62-1 or second nozzle member 62-2) includes an opening 62h for discharging food. In the example described in FIG. 5, the nozzle member 62-1 includes a plurality of nozzles including a first nozzle 621 and a second nozzle 622. The opening area (or diameter) of the discharge portion (first opening) of the first nozzle 621 is smaller than the opening area (or diameter) of the discharge portion (second opening) of the second nozzle 622. Further, the opening area (or diameter) of the discharge portion (second opening) of the second nozzle 622 is smaller than the opening area (or diameter) of the discharge portion (third opening) of the third nozzle 623. The nozzle member 62-1 includes, for example, a switching valve 620 that is operated by a command from the control device 30. The switching valve 620 selectively feeds one of a plurality of nozzles (621, 622, 623). More specifically, when the switching valve 620 operates so that the food supply pipe 64 and the first nozzle 621 communicate with each other based on the command from the control device 30, the food is discharged from the opening of the first nozzle 621. .. Further, when the switching valve 620 operates so that the food supply pipe 64 and the second nozzle 622 communicate with each other based on the command from the control device 30, the food is discharged from the opening of the second nozzle 622. The bait discharged from the second nozzle 622 is thicker than the bait discharged from the first nozzle 621. Further, when the switching valve 620 operates so that the food supply pipe 64 and the third nozzle 623 communicate with each other based on the command from the control device 30, the food is discharged from the opening of the third nozzle 623. The bait discharged from the third nozzle 623 is thicker than the bait discharged from the second nozzle 622.

In the example shown in FIG. 5, the second nozzle member 62-2 includes one nozzle. The bait discharged from the nozzle of the second nozzle member 62-2 is larger than the bait discharged from the nozzle of the nozzle member 62-1 (for example, the first nozzle 621, the second nozzle 622, or the third nozzle 623). thick. Alternatively, the thickness of the bait discharged from the nozzle of the second nozzle member 62-2 may be about the same as the thickness of the bait discharged from the third nozzle 623.

The moving device 63 is a device that moves the nozzle member 62 relative to the bait support portion PL. In the example described in FIG. 5, the moving device 63 is a nozzle moving device that moves the nozzle member 62. Alternatively, the moving device 63 may be a device that moves the bait support PL.

The mobile device 63 and the control device 30 are connected by wire or wirelessly so as to be able to transmit signals, and the mobile device 63 operates based on a command from the control device 30. The moving device 63 changes the position of the nozzle member 62 three-dimensionally based on a command from the control device 30. In the example described in FIG. 5, the moving device 63 includes a robot arm 630.

In the example described in FIG. 5, the moving device 63 (more specifically, the moving device 63-1) moves the nozzle member 62-1 relative to the bait support portion PL. The food support unit PL is, for example, a food support unit arranged in the first breeding container C1. The bait support portion PL is preferably composed of a mesh-like member (in other words, a net-like member). In this case, the silk moth droppings fall below the bait support portion PL through each opening of the mesh-like member. Therefore, in the region above the food support portion PL, the silk moth breeding environment is unlikely to deteriorate.

In the example described in FIG. 5, the moving device 63 (more specifically, the second moving device 63-2) moves the second nozzle member 62-2 relative to the bait support portion PL. The food support unit PL is, for example, a food support unit to be arranged in the second breeding container C2. The bait support portion PL is preferably composed of a mesh-like member (in other words, a net-like member). In this case, the silk moth droppings fall below the bait support portion PL through each opening of the mesh-like member. Therefore, in the region above the food support portion PL, the silk moth breeding environment is unlikely to deteriorate.

(Partition member P)
In the example shown in FIG. 5, the partition member P is arranged inside the first breeding container C1. As shown in FIG. 6, the partition member P (more specifically, the first partition member P1) fills the space inside the first breeding container C1 with the first region R1 where the silk moths are grown and the entry of the silk moths. Is a member that partitions the second region R2 (that is, a region where silk moths cannot enter). The positions of the partition member P are the first position (see the upper diagram of FIG. 6) that partitions the first region R1 and the second region R2, and the second position (see FIG. 6) in which the partition state by the partition member is released. The position can be changed to (see the figure below). The first position (in other words, the partition position) is, for example, the position of the partition member P when the partition member P is arranged in the first breeding container C1. The second position (in other words, the non-partitioning position) is, for example, the position of the partitioning member P when the partitioning member P is removed from the first breeding container C1.

(Partition member moving device 70)
In the example described in FIG. 7, the silk moth breeding system 1B includes a partition member moving device 70 for moving the partition member P arranged in the first breeding container C1. The partition member moving device 70 moves, for example, the partition member P from the first position inside the first breeding container C1 to the second position outside the first breeding container C1.

In the example described in FIG. 7, the partition member moving device 70 includes a partition member holding portion 71 and a holding portion moving device 72. The partition member holding portion 71 is a portion capable of holding the partition member P. The partition member holding portion 71 may include a first grip portion 71a and a second grip portion 71b. In this case, the partition member holding portion 71 can grip the partition member P by reducing the distance between the first grip portion 71a and the second grip portion 71b. Alternatively, the partition member holding portion 71 may include a hook portion 71c (see FIG. 5 if necessary) capable of suspending the partition member P.

The holding unit moving device 72 includes, for example, a robot arm. The robot arm of the holding portion moving device 72 may be the robot arm 630 of the moving device 63-1 shown in FIG. 5, or may be a robot arm different from the robot arm 630 of the moving device 63-1. Good. The shape and structure of the partition member moving device 70 are not particularly limited as long as the partition member P can be moved.

The partition member moving device 70 and the control device 30 are connected by wire or wirelessly so as to be able to transmit signals, and the partition member moving device 70 operates based on a command from the control device 30. More specifically, the partition member holding portion 71 of the partition member moving device 70 holds the partition member P based on a command from the control device 30. After that, the holding unit moving device 72 of the partition member moving device 70 moves the partition member holding unit 71 in the direction from the first position to the second position based on the command from the control device 30. In this way, the partition member P is removed from the first breeding container C1.

(1st silk moth breeding process)
An example of the first breeding step (first step ST1 described above) in which a plurality of silk moths A are bred in the first breeding container C1 will be described in more detail with reference to FIGS. 8 and 9.

In step ST201, a plurality of silk moths are bred in the first region R1 on one side of the first partition member P1 arranged in the first breeding container C1. Step ST201 is executed, for example, in the first breeding container C1 arranged in the first breeding container storage area AR1. In the example described in FIG. 9B, a plurality of first breeding containers C1 are housed in the first breeding container storage area AR1. The number of the first breeding container C1 housed in the first breeding container storage area AR1 is, for example, 10 or more, 50 or more, or 100 or more.

In step ST201, the bait F and the plurality of silk moths A are arranged in the first region R1. Further, in step ST201, the bait F and the silk moth A are not arranged in the second region R2.

The silk moth food F is supplied to the first region R1 of the first breeding container C1 in advance. The supply of food to the first region R1 is performed, for example, via the nozzle member 62-1 of the food supply device 60 (more specifically, the first nozzle 621 described above) (see FIG. 9A). .). The thickness (in other words, the diameter) of the bait supplied to the first region R1 is, for example, 3 mm or less, or 2 mm or less. The plurality of silk moths A in the first region R1 grow by feeding on the food F in the first region R1. When the bait support portion PL is a mesh-like member (in other words, a net-like member), the silk moth feces M falls below the bait support portion PL. Therefore, the breeding environment of silk moths on the feed support PL does not deteriorate.

In step ST202, the bait F is supplied to the second region R2 on the other side of the first partition member P1. Step ST202 is performed after, for example, the first breeding container C1 is transported from the first breeding container storage area AR1 toward the food supply device 60.

The supply of the bait F to the second region R2 is performed, for example, via the nozzle member 62-1 (more specifically, the above-mentioned second nozzle 622) of the bait supply device 60 (FIG. 9C). reference.). In step ST202, since the silk moth A does not exist in the second region R2, the silk moth A does not interfere with the supply of the food F to the second region R2. The thickness of the bait F supplied from the second nozzle 622 is preferably thicker than the thickness of the bait F supplied from the first nozzle 621. The thickness (in other words, the diameter) of the bait F supplied from the second nozzle 622 is, for example, 6 mm or less, or 5 mm or less.

In step ST203, the state (partitioned state) in which the first region R1 and the second region R2 are partitioned by the first partition member P1 is released (see FIG. 9D). The release is executed, for example, by the partition member moving device 70 moving the first partition member P1. In the example described in FIG. 9D, the release is executed by the partition member moving device 70 removing the first partition member P1 from the first breeding container C1. In the example described in FIG. 9D, the partition member moving device 70 includes a hook portion 71c that can be engaged with the engaging portion Pa of the partition member P. Alternatively, the partition member moving device 70 may include a grip portion capable of gripping the partition member P.

When the partition state by the first partition member P1 is released, the first region R1 and the second region R2 are united, so that the region where a plurality of silk moths A are bred becomes large. Therefore, a more appropriate breeding environment is provided for the plurality of silk moths grown in the first region R1. Also,

After executing step ST203, the first breeding container C1 is transported to the first breeding container storage area AR1. The first breeding container C1 is supplied with fresh food F in step ST202. Therefore, the plurality of silk moths A eat fresh food and grow further.

In the example described in FIG. 9, a second partition member P2 is arranged in the first breeding container C1 in addition to the first partition member P1. The second partition member P2 partitions a new first region Rn1 (enlarged first region) and a new second region Rn2 after the first partition member P1 is removed from the first breeding container C1. It is a member (see FIG. 9D).

When the second partition member P2 is arranged in the first breeding container C1, the food F is supplied to the new second region Rn2 in step ST204. Step ST204 is performed after, for example, the first breeding container C1 is transported from the first breeding container storage area AR1 toward the food supply device 60.

The supply of food to the new second region Rn2 is performed, for example, via the nozzle member 62-1 of the food supply device 60 (more specifically, the third nozzle 623 described above) (FIG. 9 (e)). See.). The thickness of the bait F supplied from the third nozzle 623 is preferably thicker than the thickness of the bait F supplied from the second nozzle 622. The thickness (in other words, the diameter) of the bait F supplied from the third nozzle 623 is, for example, 7 mm or less.

In step ST205, the state (partitioned state) in which the new first region Rn1 and the new second region Rn2 are partitioned by the second partition member P2 is released (see FIG. 9 (f)). The release is executed, for example, by the partition member moving device 70 moving the second partition member P2. In the example described in FIG. 9, the release is executed by the partition member moving device 70 removing the second partition member P2 from the first breeding container C1.

In the example described in FIG. 9, the first breeding container C1 is a tray (in other words, a relatively shallow container with an open upper part). Since the upper part of the first breeding container C1 is open, the partition member P can be easily removed from the first breeding container C1.

In the example shown in FIG. 9, the number of partition members P arranged in the first breeding container C1 is two. Alternatively, the number of partition members P arranged in the first breeding container C1 may be one or three or more. Further, in the example shown in FIG. 6, the partition member P has an L-shape in a plan view. However, the shape of the partition member P is not limited to the example shown in FIG. For example, as shown in FIG. 10, the partition member P may have a square frame shape in a plan view.

(Egg transfer device 80)
An example of an egg transfer device 80 for transferring a silk moth egg to a first breeding container C1 (for example, a tray) will be described with reference to FIGS. 11 and 12.

The egg transfer device 80 transfers the silk moth egg E from the container C3 containing the plurality of silk moth eggs E to the first breeding container C1. When the silk moth breeding system 1 has an egg transfer device 80, the work of transferring the silk moth egg E to the first breeding container C1 (for example, a tray) is automated. As a result, the breeding of silk moths is streamlined. Further, since the silk moth egg E is automatically performed by the egg transfer device 80, germs are not substantially mixed in the breeding environment of the silk moth. The egg transfer device 80 is arranged, for example, in the container 2 (more specifically, in the first container 2A). When the egg transfer device 80 is arranged in the container 2, contamination of the silk moth breeding environment with various germs is more effectively suppressed.

In the example described in FIG. 11, the egg transfer device 80 is a suction tube moving device 86 that moves the suction tube 81 that sucks the silk moth egg E in the liquid and the suction tube 81 relative to the first breeding container C1. And include. In the liquid, the dead silk moth egg E1 is more likely to float than the live silk moth egg E2. Therefore, by sucking the silk moth eggs in the liquid (more specifically, the silk moth eggs submerged in the liquid), it is possible to select and pick up the live silk moth eggs E2.

The liquid in the container C3 is, for example, a disinfectant. The silk moth egg E is sterilized by immersing the silk moth egg E in the disinfectant solution in the container C3. In this case, when the silk moth egg E is transferred to the first breeding container C1, the risk of contamination by various germs in the first breeding container C1 is reduced.

From the viewpoint of facilitating the pick-up of the silk moth egg E from the container C3, it is preferable that the tip portion of the container C3 has a tapered shape that tapers toward the tip. Since the tip of the container C3 has a tapered shape, a plurality of silkmoth eggs E tend to gather near the bottom of the container C3. Therefore, the tip of the suction tube 81 can be arranged in the vicinity of the silk moth egg E simply by inserting the suction tube 81 into the vicinity of the bottom of the container C3 (in other words, the deepest part of the container C3).

In the example shown in FIG. 11, the suction pipe 81 is connected to the vacuum pump 84 via the pipe 82. Further, an on-off valve 83 is arranged in the pipe 82. When the on-off valve 83 is opened while the tip of the suction tube 81 is located in the liquid in the container C3, the suction tube 81 sucks one silk moth egg E. Alternatively, a suction force may be generated in the suction tube 81 by moving the piston relative to the cylinder. In this case, the vacuum pump 84 may be omitted.

After the suction tube 81 sucks the silk moth egg E, the suction tube moving device 86 moves the suction tube 81 in the direction from the container C3 to the first breeding container C1. When the tip of the suction tube 81 comes above the first breeding container C1, the suction tube 81 releases the silk moth egg E. The release may be performed by sending air to the suction pipe 81 or by opening the suction pipe 81 to the atmosphere.

In the example shown in FIG. 11, the partition member P is arranged in the first breeding container C1. In this case, it is preferable that the egg transfer device 80 transfers the silk moth egg E only to the region (first region R1) on one side of the partition member P. In other words, it is preferable that the egg transfer device 80 does not transfer the silk moth egg E to the region (second region R2) on the other side of the partition member P. When the partition member P is not arranged in the first breeding container C1, the egg transfer device 80 may transfer the silk moth egg E to an arbitrary position in the first breeding container C1.

The transfer of the silk moth egg E by the egg transfer device 80 may be performed after the bait F is placed in the first breeding container C1 (more specifically, the first region R1), or the first breeding container. It may be executed before the bait F is placed in C1 (more specifically, the first region R1).

In the example described in FIG. 11, the suction pipe moving device 86 can move the suction pipe 81 along the vertical direction (in other words, the Z direction). Further, in the example shown in FIG. 11, the suction pipe moving device 86 can move the suction pipe 81 along the first horizontal direction (in other words, the X direction).

As shown in FIG. 12, the egg transfer device 80 may include a plurality of suction tubes 81. When the egg transfer device 80 includes a plurality of suction tubes 81, the egg transfer device 80 can move the plurality of silkmoth eggs to the first breeding container C1 at the same time. In the example shown in FIG. 12, the egg transfer device 80 includes six suction tubes 81. Alternatively, the egg transfer device 80 may include one, two, three, four, five, or seven or more suction tubes 81.

In the example described in FIG. 12, the suction pipe moving device 86 can move the suction pipe 81 along the second horizontal direction (in other words, the Y direction perpendicular to the X direction and the Z direction). .. In the example shown in FIGS. 11 and 12, the suction pipe moving device 86 can move the suction pipe 81 three-dimensionally. Alternatively, the suction tube moving device 86 may be able to move the suction tube 81 two-dimensionally (for example, the suction tube moving device 86 may only move the suction tube along a plane parallel to the XZ plane. 81 may be movable.).

As shown in FIG. 13, the silk moth breeding system 1 may include a transport device 41 for transporting the first breeding container C1 between the egg transfer device 80 and the first breeding container storage area AR1. In the example described in FIG. 13, the transport device 41 is a transport device different from the first breeding container transport device 40. The transport device 41 can transport the first breeding container C1 along, for example, the vertical direction (in other words, the Z direction) and the first horizontal direction (for example, the X direction). The transfer device 41 includes, for example, a conveyor or a transfer device with a transfer device for transferring the first breeding container C1 to the shelf T1.

(Other components of silk moth breeding system 1)
Other components of the silk moth breeding system 1 will be described with reference to FIG.

The silk moth breeding system 1 may include a monitoring personal computer 101. The monitoring personal computer 101 monitors the status of each device (10, 20, 30, 40, 41, 60, 70, 80, 92). When an abnormality exists in each device (10, 20, 30, 40, 41, 60, 70, 80, 92), the monitoring personal computer 101 identifies the information for identifying the abnormal device and the type of the abnormality. Notify the worker of the information. In the above-described embodiment, an example in which the control device 30 controls each device (10, 20, 30, 40, 41, 60, 70, 80, 92) has been described. Alternatively, the monitoring personal computer 101 and the control device 30 may cooperate to control each device (10, 20, 30, 40, 41, 60, 70, 80, 92).

The silk moth breeding system 1 may include a cocoon collecting device 103. The cocoon collecting device 103 is a device that collects cocoons from the second breeding container C2 (for example, a robot that collects cocoons from the second breeding container C2).

The silk moth breeding system 1 may include a cleaning device 105 for cleaning the first breeding container C1 and / or the second breeding container C2. The cleaning device 105, for example, blows air onto the first breeding container C1 (or the second breeding container C2) to remove feces or residual food from the first breeding container C1 (or the second breeding container C2). The feces taken out from the first breeding container C1 (or the second breeding container C2) may be collected for use as feed for other livestock or as a component of a medicine. When the silk moths are bred in a sterile environment, the silk moth droppings are also kept sterile. Therefore, the silk moth droppings are suitable as feed for other livestock or as a component of medicine.

In the above example, the cleaning device 105 is an air cleaning device using air. Alternatively or additionally, the cleaning device 105 sprays water or a disinfectant solution on the first breeding container C1 (or the second breeding container C2) to spray the first breeding container C1 (or the second breeding container C2). It may be a device for removing feces or residual food from C2).

The first breeding container C1 washed by the washing device 105 is reused for breeding silk moths in the first breeding container storage area AR1. Further, the second breeding container C2 washed by the washing device 105 is reused for breeding silk moths in the second breeding container storage area AR2.

In the example shown in FIG. 13, the monitoring personal computer 101, the cocoon collecting device 103, and the cleaning device 105 are arranged in the first container 2A. Alternatively, at least one of the monitoring personal computer 101, the cocoon collecting device 103, and the cleaning device 105 may be arranged in the second container 2B. Alternatively, at least one of the monitoring personal computer 101, the cocoon collecting device 103, and the cleaning device 105 may be arranged outside the container 2.

(How to raise silk moths)
Subsequently, an example of the silk moth breeding method in the second embodiment will be described with reference to FIGS. 13 to 16.

In the first step ST1, a plurality of silk moths are bred in the first breeding container C1. The first step ST1 is the first silk moth breeding step.

In the first step ST1, first, in step ST101, the silk moth feed F is supplied to the first breeding container C1 (more specifically, the first region R1). Step ST101 is performed, for example, using the food supply device 60 described above. More specifically, the first nozzle 621 moves relative to the first breeding container C1 (more specifically, the first region R1), while the first nozzle 621 moves relative to the first breeding container C1 (more specifically, the first breeding container C1 (more specifically). Specifically, the bait F is discharged into the first region R1).

In step ST102, a plurality of silkmoth eggs E are transferred to the first breeding container C1. Step ST102 is performed, for example, using the egg transfer device 80 described above. More specifically, the transfer device 41 conveys the first breeding container C1 toward the egg transfer device 80, and then the egg transfer device 80 transfers a plurality of eggs from the container C3 to the first breeding container C1. Reprint silk moth egg E. The number of silk moth eggs E arranged in one first breeding container C1 is, for example, 10 or more and 1000 or less, 30 or more and 500 or less, or 50 or more and 300 or less. The first breeding container C1 is preferably sterilized with a disinfectant solution or the like in advance before the plurality of silk moth eggs E are transferred. The sterilized silk moth egg E is transferred to the sterilized first breeding container C1, and the first breeding container C1 is placed in the sterile atmosphere AT to be bred in the first breeding container C1. The sterilization of silk moths is maintained.

Step ST102 may be executed before step ST101 or after step ST101. After executing steps ST101 and ST102, the first breeding container C1 is transported to the first breeding container storage area AR1 by the transport device 41.

After that, the above-mentioned steps ST201 to ST205 are executed.

In step ST201, a plurality of silk moths A are bred in the first breeding container C1 (more specifically, in the first region R1). When the first partition member P1 is arranged in the first breeding container C1, the first breeding period in which the silk moth is bred in the first region R1 defined by the first partition member P1 is several days (for example, 5). Days).

After the lapse of the first breeding period, the first breeding container C1 is transported from the first breeding container storage area AR1 toward the food supply device 60. The transfer is performed using, for example, a transfer device 41 or the like.

In step ST202, the silk moth feed F is supplied to the first breeding container C1 (more specifically, the second region R2). Step ST202 is performed, for example, using the food supply device 60 described above. More specifically, the second nozzle 622 moves relative to the first breeding container C1 (more specifically, the second region R2), while the second nozzle 622 moves relative to the first breeding container C1 (more specifically, the second region R2). Specifically, the bait F is discharged into the second region R2).

In step ST203, the first partition member P1 is moved from the first position (partition position) to the second position (non-partition position). Step ST203 is executed, for example, by using the partition member moving device 70 described above.

After the execution of step ST203, the first breeding container C1 is transported to the first breeding container storage area AR1 by the transport device 41 or the like. After the execution of step ST202 (in other words, after the second feeding), the second breeding period in which the silk moths are bred within the new first region Rn1 defined by the second partition member P2 is several days (for example, after the second feeding). 5 days).

After the lapse of the second breeding period, the first breeding container C1 is transported from the first breeding container storage area AR1 toward the food supply device 60. The transfer is performed using, for example, a transfer device 41 or the like.

In step ST204, the silk moth feed F is supplied to the first breeding container C1 (more specifically, the new second region Rn2). Step ST204 is performed, for example, using the food supply device 60 described above. More specifically, the third nozzle 623 moves relative to the first breeding container C1 (more specifically, the second region Rn2), while the third nozzle 623 moves relative to the first breeding container C1 (more specifically). Specifically, the bait F is discharged into the second region Rn2).

In step ST205, the second partition member P2 is moved from the first position (partition position) to the second position (non-partition position). Step ST205 is executed using, for example, the partition member moving device 70 described above.

After the execution of step ST205, the first breeding container C1 is transported to the first breeding container storage area AR1 by the transport device 41 or the like. After the execution of step ST204 (in other words, after the third feeding), the third breeding period in which the silk moths are bred in the first breeding container C1 is several days (for example, 5 days).

In the above example, the feed F is supplied to one first breeding container C1 three times in total every few days. Alternatively, the number of times the food is supplied to one first breeding container C1 may be once, twice, or four times or more. When the feed F is supplied to the first breeding container C1 every few days, the silk moth A can grow by eating a fresh feed. On the other hand, when the food F is supplied to the first breeding container C1 only once, the food F may be deteriorated due to drying or the like.

The total period in which the silk moths are bred in the first breeding container C1 (for example, the total of the first breeding period, the second breeding period, and the third breeding period) is a dozen days (for example, 15 days). is there. In this case, in the first breeding container C1, the silk moth grows from an egg to a 4th instar larva.

After the execution of the first step ST1 (first breeding step), in the second step ST2, a plurality of silk moths (for example, a plurality of 4th instar larvae) in the first breeding container C1 are transferred to the second breeding container C2. To. The transfer is performed using the silk moth transfer device 10.

In the second step ST2, first, the first breeding container C1 and the second breeding container C2 are transported to the silk moth transfer area AR.

In the example described in FIG. 13, as shown by the broken line B1, the first breeding container C1 is transported from the first breeding container storage area AR1 to the silk moth transfer area AR. The transfer of the first breeding container C1 to the silk moth transfer area AR may be performed using a plurality of transfer devices including the first breeding container transfer device 40. In the example described in FIG. 13, the first breeding container storage area AR1 is in the first container 2A, and the silk moth transfer area AR is in the second container 2B. Therefore, the first breeding container C1 is transported from the first container 2A to the second container 2B. The transportation of the first breeding container C1 from the first container 2A to the second container 2B is performed through the container connecting portion 95.

In the example described in FIG. 13, as shown by the broken line B2, the second breeding container C2 is transported from the second breeding container storage area AR2 to the silk moth transfer area AR. The transfer of the second breeding container C2 to the silk moth transfer area AR may be performed by using a plurality of transfer devices including the second breeding container transfer device 20. In the example described in FIG. 13, the second breeding container transport device 20 is arranged in the second breeding container storage area AR2.

In the example described in FIG. 13, the second breeding container storage area AR2 is in the second container 2B, and the food supply device 60 is in the first container 2A. In this case, in order to supply the food F to the second breeding container C2, the second breeding container C2 is transported from the second breeding container storage area AR2 in the second container 2B to the food supply device 60 in the first container 2A. Will be done. The transport is performed using, for example, a plurality of transport devices including the second breeding container transport device 20 and the first breeding container transport device 40.

In the example shown in FIG. 13, the silk moth transfer area AR is in the second container 2B. Therefore, after the food F is supplied to the breeding room SP of the second breeding container C2, the second breeding container C2 is placed in the first container 2A to the second container 2B (more specifically, in the second container 2B). It is transported to the silk moth transfer area AR).

After the first breeding container C1 and the second breeding container C2 are transported to the silk moth transfer area AR, the silk moth transfer device 10 transfers the silk moth A from the first breeding container C1 to the breeding room of the second breeding container C2. To put. The number of silk moths A transferred to each breeding room of the second breeding container C2 is preferably one. By raising silk moth A individually, the stress of silk moth A is reduced.

In the example described in FIG. 14, a plurality of opening OPs are formed in the first end Ca of the second breeding container C2. Each of the plurality of opening OPs corresponds to the entrances of the plurality of breeding room SPs. The silk moth transfer device 10 transfers the silk moth A to each breeding room SP through the opening OP. In the example described in FIG. 14, the opening OP is formed on the side of the second breeding container C2. After the plurality of silk moths are housed in the second breeding container C2, the plurality of opening OPs are covered with a lid member CL (see FIG. 1 if necessary). It is preferable that the lid member CL is formed with ventilation holes. The lid member CL is a member that changes a state between a first state in which a plurality of opening OPs are opened and a second state in which a plurality of opening OPs are closed by the lid member CL. The first state means that the silk moth can be inserted into the breeding room SP through the opening OP, and the second state means that the silk moth cannot escape from the breeding room SP through the opening OP. Means. It is preferable that one lid member CL can close a plurality of opening OPs at the same time. In this case, the lid member CL can efficiently close the plurality of openings OP.

The shape of each breeding room SP is, for example, an elongated shape. More specifically, the depth of the breeding room SP is more than twice the height of the breeding room SP, and the depth of the breeding room SP is more than twice the width of the breeding room. When the shape of the breeding room SP is an elongated shape, the space for individually raising a plurality of silk moths can be relatively small. In the example described in FIG. 14, the length of each breeding room SP in the depth direction (in other words, the length in the direction from the first end Ca to the second end Cb of the second breeding container C2) is, for example. , 20 cm or more, 30 cm or more, or 40 cm or more. The longitudinal direction of the breeding chamber SP is preferably substantially parallel to the horizontal plane (in other words, the angle formed between the longitudinal direction of the breeding chamber SP and the horizontal plane is preferably 20 degrees or less). Further, it is preferable that the above-mentioned opening OP is formed at the end portion in the longitudinal direction of the breeding room SP.

In the example described in FIG. 14, the second breeding container C2 includes a plurality of breeding chambers SP. The number of breeding room SPs included in the second breeding container C2 is, for example, 10 or more and 1000 or less, 30 or more and 500 or less, or 50 or more and 300 or less. It is preferable that a food support portion PL that supports the food F is arranged in each breeding room SP. The bait support portion PL is composed of, for example, a mesh-like member (in other words, a net-like member). In this case, the silk moth droppings fall below the bait support portion PL through each opening of the mesh-like member. Therefore, in the region above the food support portion PL, the silk moth breeding environment is unlikely to deteriorate.

The food support portion PL is provided from the first end Ca (in other words, the first end in the longitudinal direction of the second breeding container C2) to the second end Cb (in other words, the second) of the second breeding container C2. It is preferable that it extends along the direction toward the second end in the longitudinal direction of the breeding container C2). Further, the bait F arranged on the bait support portion PL preferably extends along the direction from the first end Ca to the second end Cb of the second breeding container C2.

In the example shown in FIG. 14, each of the breeding chambers SP is formed by an independent tubular container CY, and an aggregate of the tubular container CY constitutes at least a part of the second breeding container C2. .. The second breeding container C2 may be formed by surrounding the plurality of tubular containers CY with the housing member H. In this case, the tubular container CY provides a first aseptic atmosphere, and the housing member H accommodating the plurality of tubular container CYs provides a second aseptic atmosphere to accommodate the second breeding container C2. 2 The rearing container storage area AR2 (or container 2 such as the second container 2B) provides a third sterile atmosphere. Therefore, the aseptic state in the breeding room SP is more reliably maintained. Further, by setting the degree of sterility stepwise, it is possible to realize the sterility state in the breeding room SP efficiently and at low cost.

Alternatively, as shown in FIG. 15, each of the breeding chambers SP may be defined by a partition wall J arranged within the housing member H. In this case, the partition wall J provides a first aseptic atmosphere, the housing member H accommodating the partition wall J provides a second aseptic atmosphere, and the second breeding container storage accommodating the second breeding container C2. Region AR2 (or container 2 such as second container 2B) provides a third sterile atmosphere. Therefore, the aseptic state in the breeding room SP is more reliably maintained. Further, by setting the degree of sterility stepwise, it is possible to realize the sterility state in the breeding room SP efficiently and at low cost.

In the examples shown in FIGS. 14 and 15, the cross-sectional shape of the breeding chamber SP on the plane perpendicular to the longitudinal direction of the breeding chamber is a quadrangular shape. Alternatively, the cross-sectional shape of the breeding room SP in a plane perpendicular to the longitudinal direction of the breeding room may be hexagonal, octagonal, or other polygonal. Alternatively, the cross-sectional shape of the breeding chamber SP on the plane perpendicular to the longitudinal direction of the breeding chamber may be circular.

In the example described in FIG. 13, after a plurality of silk moths have been transferred from the first breeding container C1 to the second breeding container C2, the second breeding container C2 is transferred from the silk moth transfer area AR to the second breeding container storage area. It is transported to AR2. The transport is carried out using the second breeding container transport device 20 or the like. Further, after the plurality of silk moths are transferred from the first breeding container C1 to the second breeding container C2, the first breeding container C1 is transported to the cleaning device 105. The first breeding container C1 is washed by the washing device 105 and then reused for group breeding of silk moths.

In the third step ST3 (second breeding step), a plurality of silk moths are bred in the second breeding container C2. In the second silk moth breeding step, for example, each of the plurality of silk moths A is individually bred in an independent breeding room SP. In the second silk moth breeding step, each silk moth grows from the 4th instar larva to the 5th instar larva, and then the 5th instar larva makes a cocoon.

Before the 5th instar larvae make cocoons, the air conditioner 92 preferably supplies dry air to the first end Ca or the second end Cb of the second rearing container C2. Since the 5th instar larva prefers dry air, by supplying dry air to the 1st end Ca or the 2nd end Cb of the 2nd breeding container C2, the 5th instar larva is made into the 1st end Ca or the 2nd end Ca. Gather at the end Cb. In this case, it becomes easy to take out the cocoon from the first end Ca or the second end Cb (for example, the cocoon recovery device 103, more specifically, the robot has the first end Ca or the second end. It becomes easy to take out the cocoon from Cb.)

After the 5th instar larvae have made cocoons, the second breeding container C2 is transported from the second breeding container storage area AR2 toward the cocoon recovery device 103. The transfer is carried out using, for example, a transfer device such as the second breeding container transfer device 20.

In the example described in FIG. 13, the second breeding container storage area AR2 is in the second container 2B, and the cocoon collecting device 103 is in the first container 2A. Therefore, the second breeding container C2 is transported from the second container 2B to the first container 2A. In the example described in FIG. 13, the transfer of the second breeding container C2 in the first container 2A is performed by using the first breeding container transport device 40. After the cocoons are taken out from the second breeding container C2, the second breeding container C2 is transported to the cleaning device 105. The second breeding container C2 is washed by the washing device 105 and then reused for individual breeding of silk moths.

In the silk moth breeding method of the second embodiment, the breeding of silk moths having a relatively small age and the breeding of silk moths having a relatively large age are divided into different spaces, so that the space is relatively small. The silk moth can be bred efficiently. In addition, transfer of silkworms from the first breeding container C1 to the second breeding container C2, transportation of the first breeding container C1 or the second breeding container C2, transfer of the silkworm eggs to the first breeding container C1, and first breeding. At least one operation (preferably) of supplying the feed F to the container C1 or the second breeding container C2, cleaning the first breeding container C1 or the second breeding container C2, and collecting the cocoon from the second breeding container C2. All actions) are performed automatically mechanically. Therefore, the efficiency of silk moth breeding is improved, and germs are less likely to be mixed into the silk moth breeding environment.

When the first breeding container C1 and / or the second breeding container C2 is washed and reused, the first breeding container C1 and / or / or the first breeding container C1 and / or the inside of the sterile atmosphere (for example, the container 2) from outside the sterile atmosphere. It is possible to repeatedly breed silk moths without replenishing the second breeding container C2. Therefore, the risk of germs entering the sterile atmosphere AT is reduced. The cocoons collected by the cocoon collecting device 103 may be taken out through the door DR (see FIG. 4 if necessary) of the container 2 (more specifically, the first container 2A). .. Further, the replenishment of the bait F and / or the silk moth egg E may be performed through the door DR of the container 2 (more specifically, the first container 2A). The door DR is preferably a double door from the viewpoint of preventing the invasion of various germs into the container 2.

(Silk moth transfer device 10)
An example of the silk moth transfer device 10 that can be adopted in the silk moth breeding system 1 in the embodiment will be described with reference to FIG.

In the example described in FIG. 17, the silk moth transfer device 10 has a holding member moving device 12 (more specifically, an arm portion) and a grip portion 110. The holding member moving device 12 is, for example, a robot arm including one or more joints. Further, the grip portion 110 has, for example, a plurality of grip pieces 111 including a first grip piece 111a and a second grip piece 111b. The number of gripping pieces 111 included in the gripping portion 110 may be two or three or more.

The contact portion 112 of the gripping piece 111 that comes into contact with the silk moth is preferably made of an elastically deformable member (elastic member). The contact portion 112 is formed of, for example, silicone rubber. By forming the contact portion 112 with an elastic material (for example, silicone rubber), it becomes possible to suitably grip a silk moth whose shape changes and moves.

The grip piece 111 may be, for example, a grip piece having an internal space IS surrounded by an elastic material. In this case, the gripping piece 111 can be driven by supplying a fluid such as air to the internal space IS. In the example described in FIG. 17, each grip piece 111 includes a fluid supply path PH that supplies fluid to the internal space IS.

The present invention is not limited to each of the above embodiments, and it is clear that each embodiment can be appropriately modified or modified within the scope of the technical idea of the present invention. In addition, the various techniques used in each embodiment or modification can be applied to other embodiments or modifications as long as there is no technical contradiction. Further, any additional configuration in each embodiment or modification can be omitted as appropriate. For example, each component included in the second embodiment can also be adopted in the first embodiment.

In the second embodiment, an example in which a plurality of silk moths are bred using a plurality of containers (2A, 2B) has been described. However, in the second embodiment, a plurality of silk moths may be bred using one container 2. Further, in the second embodiment, a plurality of silk moths may be bred in a sterile environment set independently of the container.

In the second embodiment, an example in which the silk moth transfer device 10 and the second breeding container transport device 20 are arranged in the second container 2B has been described. Alternatively, the silk moth transfer device 10 or the second breeding container transport device 20 may be arranged in the first container 2A. Alternatively, the silk moth transfer device 10 or the second breeding container transport device 20 may be placed in a sterile environment unrelated to the container.

Further, in the second embodiment, an example in which the first breeding container transport device 40, the feed supply device 60, the partition member moving device 70, and the egg transfer device 80 are arranged in the first container 2A will be described. It was. Alternatively, the first breeding container transport device 40, the food supply device 60, the partition member moving device 70, or the egg transfer device 80 may be arranged in the second container 2B. Alternatively, the first breeding container transport device 40, the feed supply device 60, the partition member moving device 70, or the egg transfer device 80 may be arranged in a sterile environment unrelated to the container.

Further, in the second embodiment, an example in which the silk moth transferred from the first breeding container C1 to the second breeding container C2 is a silk moth of a fourth instar larva has been described. Alternatively, the silk moth transferred from the first breeding container C1 to the second breeding container C2 may be, for example, a silk moth of a fifth instar larva. Further, when the silk moth of the 5th instar larva (more specifically, the silk moth immediately before making the cocoon) is transferred to the second breeding container C2, the placement of food in the second breeding container C2 is omitted. May be good. In this case, it is not necessary to transport the second breeding container C2 toward the feed supply device 60. Further, when the food is not arranged in the second breeding container C2, the “food support portion PL” is replaced with the “support portion” in the above description of the embodiment. The "support portion" is a support portion capable of supporting the silk moth.

Further, in the examples shown in FIGS. 14 and 15, an OP through which the silk moth can pass is arranged at the first end Ca (first end face) of the second breeding container C2. In addition, an opening through which the silk moth can pass may be arranged in the second end Cb (second end face) of the second breeding container C2.

[Embodiment 3]
The automatic sericulture system, the automatic sericulture method, the program, and the storage medium according to the third embodiment will be described with reference to FIGS. 1 to 14.

[Growth of silk moth]
Eggs hatch in about 3 days at 30 degrees or higher Count the number of days from hatching Larvae Larvae (Chisan)
Moulting 1st instar
2nd, 3rd, 4th, 3rd to 5th, group breeding 1 million can be bred.

For example, on the 15th day, when the activity of the silk moths before molting from the 3rd to the 4th instar is low, the silk moths are taken out from the group breeding container by a picking robot and moved to the individual breeding container. Alternatively, it can be bred in an individual breeding container from the time of the egg. The silk moths may be moved from the group breeding container to the individual breeding container at any stage of eggs, juvenile silk moths, 1st to 5th instars, and mature silk moths.

Since individual breeding containers are made of SUS and are expensive to manufacture, we would like to increase the frequency of use as much as possible. For this purpose, it is advantageous to carry out group breeding up to the mature silk moths and then move them to individual breeding containers after they become mature silk moths. For example, the silk moths may be reared in a group breeding container until the silk moths on the 25th day, and the mature silk moths ready to start spitting may be moved to an individual breeding container. In this case, the readiness to start spitting can be determined by detecting the following features:
・ Pee with a large amount of feces.
-Body color changes from white to yellowish transparent.
・ Lift your head.

About 5th instar silk moth (Jukusan) Continue to eat for 10 days, then pee, a large amount of feces, from white to yellow (transparent) Cocoon that starts spitting from the 25th day, 28th day, after starting to make cocoons Since the number of days to take out the cocoon is a guideline in about 3 days, the time can be specified, but the time to take out the cocoon may be adjusted by sensing. Sensing may be performed once an hour.
Look with the sensor by shining light. When the cocoon is completed, the silk moth will not move in the cocoon.
An X-ray camera or an infrared camera may be used.

When picking eggs, even the adult silk moths that break through the cocoons are bred.
One female lays about 200 eggs.

Further, it may be dried from the beginning to the end with a heat pump type dryer.
When the prepared bait is fed from the hopper, it is squeezed out by a pump, and the bait of a semi-cylindrical glock of a desired thickness can be provided in a predetermined place in the breeding container. The thickness and compounding ratio can be changed according to the growth of the silk moth. The composition of food and the adjustment of thickness are also automated.

・ Mulberry leaf dry powder (sterilized)
・ Supplementary feed Solvent degreased soy sauce and dried okara from tofu production (edible and sterilized) Amino acids and proteins are required.
・ Moisture (sterilized water and sterile water are used.)
Mix the above three to form a soft, bavarois-like kamaboko shape

Ratio 3 grams of mulberry powder (10%)
Supplementary feed 6 grams Moisture 21 grams Total 30 grams High temperature drying → Loss of nutritional components. Auxiliary additives need to be added.
Low temperature drying → Since nutritional components are not easily lost, auxiliary additives may not be needed. For example, the component called human xilia, which promotes the appetite of 1st to 3rd instar silk moths, is not lost.
-Drying in the oven (oven for treating silk moths in the cocoons) is about 80 ° C.
Drying by the heat pump method is about 50 to 60 ° C.
Drying with vacuum + microwave is about 40 ° C.
In addition, drying and pulverization may be performed as in freeze-drying.

Feed is automatically supplied to the group breeding container by the feed supply means. The thickness and compounding ratio of the feed can be adjusted according to the growth of the silk moth. In the group breeding container, the position where the feed is supplied is changed according to the growth of the silk moth. For example, when the feed is replenished on the fifth day, the feed of a predetermined compounding ratio and size (thickness) is supplied to a position adjacent to the position where the egg and the first feed are supplied. Further, when the feed is replenished on the 10th day, the feed having a predetermined mixing ratio and size (thickness) is supplied to a position further adjacent to the position of the feed arranged on the 5th day. Further, when the feed is replenished on the 15th day, the feed having a predetermined compounding ratio and size (thickness) is supplied to a position further adjacent to the position of the feed arranged on the 10th day. By shifting the position where the feed is supplied in this way, it is possible to prevent the feces from accumulating only at the specific feed position by guiding the position of the silk moth to the place where the feed is located.

[Moth transportation]
Picking Robo Soft Robotics, Sucker and Hand Example 1) Suck the silk moth about 3 cm in age with the vacuum sucker at the tip of the robot arm.
Example 2) Hold with a soft air-driven hand. A soft material made of adhesive silicone.
Example 3) Hold with a soft air-driven hand and suck up with a vacuum suction cup.
The hand that picks up the cocoon is driven by air. Grip softly. The hand that picks up the silk moth and the hand that picks up the cocoon can be automatically exchanged.

Since the silk moth pickup position 212 is a rotary table, the silk moth can be picked by the picking robot while rotating the group breeding container. For example, the position of the silk moth is determined by two-dimensional image recognition by a monocular camera. In addition, the position of the cocoon is determined by two-dimensional image recognition by the monocular camera, and the cocoon is taken out by the cocoon picking hand. One camera at the silk moth pick position and another camera at the cocoon pick position. However, it is also possible to perform three-dimensional image recognition using a two-axis camera (stereo camera). At the movement of the silk moth to the individual breeding container or the removal position 213 of the cocoon from the individual breeding container, the individual breeding container can be raised and lowered by the lifter. The movement of the silk moth to the individual breeding container and the removal of the cocoon from the individual breeding container are performed at the same position 213.

FIG. 10 is a photograph of the camera. The camera is provided above the picking robot, for example, one camera at the silk moth pick position and another camera at the cocoon pick position. Lighting means for illuminating the shooting range is provided in the vicinity of the camera.

[Egg supply means]
Sorting eggs In water, healthy eggs sink and dead eggs float. Use a robot to take out healthy eggs with a dropper. Put the eggs in a V-groove-shaped disinfectant tank. Normal eggs sink to the bottom of the V-groove. Eggs sinking to the bottom are sucked by suction means (dropper-shaped suction means, multiple side by side), and the eggs are placed in a predetermined place in the group breeding container. Arrange the eggs in multiple rows, for example 6 rows. Food is also fed in multiple rows between the egg arrangements, parallel to the egg arrangements.
As the disinfectant solution, for example, Osban solution (registered trademark) can be used. Dilute the stock solution to about 1%. Ozone water may be used. Disinfect the surface of the egg.

[Example of realizing a sericulture system in a container]
Although not particularly limited, it is also possible to house the automatic sericulture system of the present embodiment in a container.
1st Conte Work Space 2nd Container Breeding Room,
Conveyor connecting the two
You can raise about 20,000 silk moths.
If the scale is expanded, it is possible to raise silkworms in units of 1 million.

Work in the first container Sorting eggs, preparing group breeding containers, preparing individual breeding containers Addition of food Picking up silk moths Moving from group breeding containers to individual breeding containers.
You may use multiple picking robots. For example, it is possible to arrange multiple picking robots around a circular conveyor (inner circumference side or outer circumference side) such as a circumference, and pick up only mature silk moths by image recognition with a camera.

Second Container A plurality of breeding shelves for storing individual breeding containers and group breeding containers FIGS. 12 to 14 show breeding shelves and breeding container automatic storage means arranged in the second container.
FIG. 12 is a photograph of the breeding rack.
FIG. 13 is a photograph of the rail of the breeding container automatic storage means.
FIG. 14 is a photograph of the breeding container automatic storage means. The breeding container automatic storage means is provided with an elevating means and a means for storing or removing the breeding container on the breeding shelf.

[Aseptic breeding]
Features Completely sterile 70% humidity, prevent food from drying 20-25 ° C Temperature preferred by silk moths Sterile food is irresistible = silk moths are healthy and disinfect the outside of eggs. Put the eggs in the V-groove-shaped disinfectant tank and take out only the eggs that have sunk to the bottom.
-Supply aseptic feed.
・ Make the breeding environment sterilized or sterile. A clean room using an air purifier using a HEPA filter. Remove 1 micron size debris.

Egg management Specify the estimated loading date at the time of purchase from the hatcher in about 3 days at 30 degrees or higher.
Variety and quantity

When Krafen water is mixed with feed, the tensile strength of the yarn can be improved by about 1.5 times.

[Breeding method]
Feeding every 5 days Egg + feeding → (5 days later) feeding → (5 days later) feeding → (5 days later, 15 days in total, the period of immobility before molting from 3rd to 4th instar) 3 cm at 3rd instar Transfer a silk moth of about the size to a tube with a picking robot (vacuum sucker), fill the tube with food, plenty of 20 g → (25th day) Start making cocoons by spitting out threads → (3 days later, total 28th day) Take out the cocoon with a picking hand

[Washing process]
Feces are Chinese herbs, and dung falls through the gaps in the wire mesh and collects on the bottom. → Collect only feces.
The molted shells and the rest of the food remain on the wire mesh. Can be sorted.
Group breeding containers, individual breeding containers, and partition members should be washed after use. This cleaning can be automated. For example, automatic cleaning with a stream of water in the cleaning tank.

Full automation, collection of collected cocoons, collection of collected feces, collection of collected residues (leftover food, molted matter), feed replenishment, and egg replenishment can all be automated. However, one of these may be done manually.
A fully automated sericulture system can be realized.
Egg supply means, feed supply means, silk moth movement means, cocoon removal means, breeding container automatic storage means, and breeding container moving means are all automated. It is easy to sterilize and reduce the stress of silk moths without human intervention.
In traditional sericulture, it was very difficult to arrange the timing of putting in the glare and the time of sericulture. In the present embodiment, it is possible to analyze the upper stagnation time by sensing and perform variable work according to the analysis result. Monitoring (sensor), data analysis / decision making (use of AI), variable work according to analysis results (automated by robot).
When transferring to individual breeding containers at the age of 3 to 5, it is not necessary to manage the upper stagnation period. The time to remove the cocoons can be determined by the number of days or by sensing.
When only mature silk moths are selected and picked up, some silk moths grow slowly even in the same group breeding container, so group breeding can temporarily stock a group breeding container near the pickup position so that the pick-up work time can be adjusted. It is advisable to provide a container stocker.
By using IoT technology, it is possible to monitor the growth status of silk moths and optimize the work period according to the growth. For example, a camera monitors the condition of silk moths or cocoons. For example, monitor every hour.

[Individual breeding container]
Breeding spaces are provided in a matrix. For example, 5 rows x 10 rows.
One breeding space is divided into two rooms by a partition member.
To remove the cocoons, push out the partition members one by one on the workbench to half the length direction.
For example, there are 5 vertical rows and 10 horizontal rows, a partition in the center of the tube, and a net to raise the bottom, and the dung collects under the net. There is a sponge around the central partition, and if you move the partition halfway, you can scrape out the feces inside. As soon as the cocoons are removed, the primary cleaning is completed.
Detachable lids (translucent) are provided on both sides.

[Group breeding container]
The group breeding container is a substantially square bottomed container, and a water supply means for preventing drying is provided in the center. See the rectangular container at the bottom center of FIG. The water supply means may be a sponge or the like soaked with water. Alternatively, water can be directly placed in a container as a means of supplying water. A removable lid (translucent) is provided on the upper surface of the group breeding container.

[Partition member]
FIG. 6 is a photograph of the partition member. The partition member 240 is inserted into the breeding space of the individual breeding container. The partition member 240 has a partition portion 241 and a flat surface portion 243. The partition 41 divides the breeding space into two spaces. The flat surface portion 243 serves as a floor for breeding silk moths or cocoons. The flat surface portion 243 is provided with a plurality of holes, and silk moth droppings fall from the holes and collect between the bottom of the breeding space and the lower part of the flat surface portion 243. An elastic member 242 made of, for example, a sponge is provided around the partition portion 241. The elastic member 242 corresponds to the shape and size of the inner wall of the breeding space. Convex portions 246, which are convex toward the upper surface, are provided at both ends of the flat surface portion 243.

FIG. 7 is a diagram showing a case where the partition member 240 is pushed out from the breeding space by the partition member moving means 220 by a distance of half the length of the partition member 240. When the partition member 240 is pushed out from the breeding space by half in this way, the elastic member 242 is in sliding contact with the inner wall of the breeding space, so that the feces in the storage space and the residue other than the feces can be separated and taken out. FIG. 8 is a photograph of the cocoons taken out from the individual breeding containers. Since FIG. 8 is a reference photograph different from the actual installation position, it is different from the actual arrangement relationship. The position where the cocoon is taken out is the position where the partition member 240 is pushed out by half from the breeding space, and the partition member accommodating portion is in contact with the individual breeding container, and the protruding partition member 240 is fitted into the partition member accommodating portion. Has been done. In this state, the feces are scraped out by the elastic member 242 and collected by the feces collection container. On the other hand, leftover food, peeled skin, and the like, which are residues other than feces, remain on the flat surface portion 243, so that feces and residues other than feces can be separated and taken out.

In order to return the partition member 240 into the breeding space from the position shown in FIG. 7, the claw portion provided on the partition member moving means 220 is adapted to engage with the convex portion 246. Since the individual breeding container is placed on the lifter, its height can be adjusted. The individual breeding container has, for example, a total of 50 breeding spaces in 5 rows and 10 rows. There are 10 breeding spaces in each stage, and the partition member 240 inserted in the 10 storage spaces in each stage can be moved at the same time by the 10 arms of the partition member moving means 220. Engagement and disengagement between the claw portion and the convex portion 246 provided on the partition member moving means 220 are performed by adjusting the height of the lifter. If the individual breeding container is rotated 180 degrees, the partition member 240 can be pushed out from the breeding space by half from both sides of the 212 from the opposite side, and the partition member 240 can be pushed out from the breeding space from the opposite side as well.

[Embodiment 4]
In the present embodiment, unlike the third embodiment, a method in which a picking robot is not used when transferring from the group breeding container to the individual breeding will be described.

From the second instar (about 20 mm), transfer to the glare (multiple squares of about 50 mm x 50 mm partitioned by a partition). That is, it shifts from group breeding to individual breeding.

(Example 1)
Using, for example, a conical device (funnel 310) such as a funnel, the silk moths are placed one by one in the upper sword chamber 300. If one silk moth does not fit in each box 301, for example, if two silk moths fit in one box, or if an empty box occurs, a pick robot is used to put silk moths in each box. Move the silk moths so that they fit one by one.

Since the cocoons can be removed in about 3 days, it is possible to produce cocoons 120 times a year. It takes less days to put in the incubator.

FIG. 33 shows a modified example of the funnel 310A. A first valve 311 is provided above the extraction port of the funnel 301A, a second valve 312 is provided below the extraction port, and a valve chamber 313 is provided between the first valve and the second valve. When the first valve 311 is opened and, for example, one silk moth moves to the first valve chamber, the first valve 311 is closed immediately, so that one silk moth moves to the valve chamber 313. Next, when the second valve 312 is opened, one silk moth is extracted from the funnel 310 into one box 301 from the valve chamber. As a result, one silk moth can be accommodated in each box 301. When a sensor is provided on the valve 313, the first valve 311 and the second valve 312 can be controlled according to the detection of the silk moth by the sensor. This makes it possible to move the silk moths one by one to the valve chamber and reliably extract the silk moths one by one from the funnel.

(Example 2)
An individual moving box 330 partitioned into a plurality of boxes 331 is placed on the group breeding container 320. The inner dimensions of the group breeding container 320 substantially match the outer dimensions of the individual moving box 330. Since the silk moth has a habit of climbing upward and a habit of keeping a distance from other silk moths, one silk moth enters each box of the box member by itself.

(Modified Example 2-1 of Example 2)
Instead of the grid-shaped box members, for example, a wavy partition member in which a plurality of wavy partition members are laminated, that is, a wavy individual moving box 333 provided with a plurality of wavy box members 333 is used. Since it is easier to manufacture the partition member than to manufacture the box member, the device is cheaper. The partition member is not limited to a corrugated shape, and may be, for example, a continuous rectangle.

(Modification 2-2 of Example 2)
Instead of the grid-shaped box member, for example, a wire mesh type individual moving box 336 obtained by bending and molding a wire mesh 335 into a continuous corrugated shape can be used to raise the silk moth. Ripe silk moths have a habit of making cocoons in three-dimensional places. Utilizing this habit of the silk moth, the silk moth recognizes the three-dimensional space between the wire meshes formed in the wire mesh type individual moving box 336 as a three-dimensional shape, and creates a cocoon in this space.

(Modified Example 2-3 of Example 2)
Utilizing the habit of silk moths gathering in the place where there is food, the paste-like food was distributed and distributed throughout the group breeding container 320, whereby the individual moving box 330 was covered from above. Occasionally, it is possible to induce the silk moths to move one by one to the box 331.

FIG. 37A (left figure) is a diagram in which a small silk moth that has just hatched from an egg is bred in the first partition 321. The bait 325 is dispersedly arranged in the first partition 321. By gathering the silk moths on the dispersed food, the silk moths can be distributed and bred as a result.

FIG. 37B (center view) is an explanatory diagram in the case where the first partition 321 is removed and the silk moth is bred in the second partition 322 when the silk moth grows larger. The food is evenly dispersed in the second partition, and the silk moths gather in the food. As a result, the silk moths can be dispersed and bred in the second partition 322.

In FIG. 37C (right figure), when the silk moth grows larger, the second partition 322 is removed and the silk moth is bred in the entire group breeding container 320. The paste-like food is evenly distributed in the group breeding container 320. Since the silk moths collect in the food, as a result, the silk moths are distributed substantially evenly in the group breeding container 320. When the silk moths are mature in this state, if the individual moving boxes 330 are placed on the group breeding container 320, it is possible to guide the mature silk moths dispersed substantially evenly to the boxes 331 one by one.

(Example 3)
When the animals are bred in the group breeding container 320, in addition to the silk moths, silk moth droppings and residues such as food residue are accumulated in the group breeding container 320. I want to take out only the ripe silk moth in order to grow up, but if I try to take out the ripe silk moth as it is from the container, the residue will inevitably come out together. Therefore, by using a vacuum suction nozzle with an output that allows the silk moths to stay in the group breeding container 320 by themselves, it is possible to suck only the residue in the group breeding container 320 and take out only the mature silk moths at once. .. If only the mature silk moths can be taken out, the silk moths can be put into the funnel 310 of the embodiment of FIG. 32 in a batch. Furthermore, since the silk moths have the property of keeping a distance from other silk moths without using the funnel 310, the silk moths can enter each cocoon 301 one by one by simply sprinkling the mature silk moths on the upper cocoon chamber container 300. , There you can tie a cocoon.
