In one embodiment, fig. 1 is a block diagram of an application scenario of an intelligent warehouse among production processes, and the embodiment of the present application provides an intelligent warehouse among production processes, which can be applied to the application scenario shown in fig. 1, wherein an intelligent warehouse 100 among production processes includes a production transportation device 101, a controller 102, a control terminal 103, a previous production process outlet 104, and a next production process outlet 105.

The production transport device 101 includes transport lines for transport and buffer lines for materials between the previous production process outlet 104 and the subsequent production process inlet 105. The controller 102 is electrically connected to each driving device of the production transport device 103, and the controller 102 drives each transport line and each cache line to move by controlling each driving device of the transport device 101. It will be appreciated that the number and location of the previous and the next process outlets may be varied according to the actual situation, and the present application is not limited thereto.

The controller 102 may be a programmable logic controller (PLC controller), or any device for controlling a driving device, where the driving device may be a motor device, or any device for driving a transport line and a cache line to move, and the control terminal may be a terminal device or a server, which is not limited in this application.

In one embodiment, the controller 102 is a PLC controller and the drive means is a motor device connected to each of the conveyor lines and the buffer lines. Specifically, the motor equipment of each transport line and buffer line can be linked on the switch through 485 interfaces or network ports, and is connected with the PLC through the switch, and the PLC transmits I/O signals to the motor equipment through I/O point positions, so that the switch of the motor equipment can be controlled.

In one embodiment, as shown in FIG. 2, there is provided an intelligent warehouse between production processes, comprising:

a first transport line 201 provided at the previous process outlet 104; the first transport line 201 is disposed in a first direction; at least two cache lines 202 disposed between the first transport line 201 and the subsequent process inlet 105; the cache line 202 is disposed in a second direction, the first direction being perpendicular to the second direction.

Specifically, the direction in which the connection line of the previous manufacturing procedure outlet and the next manufacturing procedure inlet is located is the second direction, and at least two cache lines are disposed in the second direction. The second direction is perpendicular to the first direction, and the first transportation line is arranged in the first direction.

Wherein the outlet 104 of the previous production process is a discharge outlet of the previous production process between two continuous production processes. The semi-finished product material produced and manufactured in the previous production process flows out from the outlet 104 of the previous production process. Specifically, the semi-finished product material is a material required to be used in a subsequent process, and after the semi-finished product material is produced in the previous production process according to the production requirement, the semi-finished product material flows out to the first conveying line 201 through the outlet 104 of the previous production process.

The first transporting line 201 is a main transporting line for transporting semi-finished materials, and the first transporting line 201 is connected to the outlet of the previous manufacturing process and the inlet of each buffer line 202. Specifically, the semi-finished product material flows out of the previous process outlet 104, through the first transport line 201, and into the corresponding cache line 202.

The first transportation line 104 is disposed in a first direction, and it is understood that the first direction is a placement direction of the first transportation line 104, and is not a transportation direction of the first transportation line 104. It will be appreciated that the direction of transport of the first transport line 201 is dependent upon the relative position of the cache line 202 and the previous process outlet 104, as the application is not limited in this regard. In this embodiment, the transport direction of the first transport line 201 and the moving direction of the buffer line 202 are shown by arrows.

The buffer line 202 is a movable bearing line for buffering semi-finished products, and after the semi-finished products are produced, the semi-finished products are put into the buffer line 202 for buffering when the semi-finished products are not called by the next production process; when the next production process calls for a material, the corresponding cache line 202 of the semi-finished product material may be moved in response to the control, and the semi-finished product material may be transported to the next production process inlet 105. The next production process inlet 105 is a material inlet of the next production process, and the semi-finished product material enters the next production process through the next production process inlet 105 for use.

The controller 102, the controller 102 obtains the warehouse-in task issued by the control terminal 103, the warehouse-in task comprises warehouse-in materials produced by the previous production procedure and target warehouse-in cache lines, and the target warehouse-in cache lines are determined according to the types of the warehouse-in materials; and the controller controls the first transportation line and the target warehousing cache line to move according to the warehousing task, and transports the warehousing materials to the target warehousing cache line for caching.

The warehousing task is a task generated by the control terminal according to the warehousing materials and a preset warehousing rule, and comprises the warehousing materials produced by the previous production process and a target warehousing cache line. Specifically, after the semi-finished product materials are produced in the previous production process, the control terminal receives the material information of the semi-finished product materials by calling the standard interface. The material information comprises material names, material codes, quantity, machine numbers and the like.

Wherein, the material codes are in one-to-one correspondence with the semi-finished product materials to be put in storage. It will be appreciated that the number of semi-finished products in the same batch may be one or more, and the specific number may be determined according to the production requirement of the subsequent process. The same batch of semi-finished material is transported into the same buffer line as a whole, corresponding to a material code. If the material called in the next process is a screw, the number of the screws in the same batch can be determined according to the number of the screws used in the next process in one production, the screws in the same batch are taken as a whole, and the screws in the same batch are corresponding to a material code and are transported to a corresponding target storage cache line.

The target warehousing cache line is determined by the control terminal according to a preset warehousing rule and material information of warehousing materials, and specifically, the preset warehousing rule is a preset warehousing logic basic principle.

Specifically, after the semi-finished product materials are produced according to the production requirement in the previous production process, the control terminal 103 generates a corresponding warehousing task according to the semi-finished product material information and a preset warehousing rule, the controller 102 acquires the warehousing task, and controls the first transportation line 201 and the corresponding target warehousing cache line to move according to the warehousing materials in the warehousing task and the target warehousing cache line corresponding to the warehousing materials, so that the warehousing materials are transported to the corresponding target warehousing cache line, and after the task is completed, the movement of the target warehousing cache line is stopped, and the warehousing materials are cached on the target warehousing cache line.

In one embodiment, the preset binning rules include, but are not limited to, the following:

first, the material codes belong to the same kind of material and enter the same cache line for caching. When the next procedure is called, the needed semi-finished product materials can be obtained from the corresponding cache lines according to the types of the material codes in sequence, and the method is more convenient and quick.

Secondly, when the warehouse-in sequence is based on the condition that the warehouse-in sequence is close to the entrance of the next working procedure, and the target cache line corresponding to the materials is generated, the cache line of the same coded materials closest to the entrance of the next working procedure is preferentially considered. The principle can reduce the time for the semi-finished product material to reach the inlet of the next working procedure to the greatest extent and improve the production efficiency.

Thirdly, if the same coded material cache line matched with the material to be stored currently is not available in the warehouse, the storage time of the last storage material in each cache line is obtained, and the current material is stored in the cache line with longer storage time preferentially according to the storage time. The longer the warehousing time of the last warehousing material is, the material on the cache line is about to be used as called material, and the materials coded by different materials are put into the cache line for caching, so that the materials can be consumed in the fastest time, and the disorder of the coding types of the materials in the cache line is prevented.

Specifically, the control terminal generates a warehouse-in task according to the material information and a preset warehouse-in rule, wherein the warehouse-in task comprises warehouse-in materials and target warehouse-in cache lines corresponding to the warehouse-in materials. It can be understood that the preset warehousing rules can be stored in a database of the control terminal in advance, can also be stored in a cloud storage library, and can be called when the warehousing tasks are produced.

In one embodiment, the preset warehousing rules are encapsulated in a standard interface called when the control terminal receives the material information, wherein the standard interface can be an API interface. Specifically, when the control terminal receives the material information by calling the standard interface, the material information triggers a preset warehousing principle of standard interface encapsulation, and the control terminal generates a corresponding warehousing task according to the preset warehousing rule and the material information.

In one embodiment, a predetermined number of material cache locations are provided on the cache line 202, each having a corresponding bank number, and the cache line 202 moves in response to control by the controller to transfer the semi-finished material to the corresponding target cache location.

The controller 102 generates corresponding binning task completion information according to binning tasks, and sends the binning task completion information to the control terminal 103.

The warehousing task completion information is determined according to warehousing materials and target warehousing cache lines. Specifically, the warehouse-in materials have corresponding material codes, the controller 102 controls the first transportation line 201 and the target warehouse-in cache line to move, after the warehouse-in materials are put into the corresponding target warehouse-in cache line to be cached, warehouse-in task completion information is generated according to the material codes and the target warehouse-in cache line, and the warehouse-in task completion information is sent to the control terminal 103. The control terminal 103 can determine the specific position of the warehouse-in material corresponding to the material code according to the returned warehouse-in task completion information, so that overall planning management is facilitated.

In one embodiment, the binning task may further include binning task numbers, the binning task numbers correspond to binning material codes and target binning cache lines one by one, and after the binning task is completed by the controller 103, binning task completion information is generated according to the binning task numbers, and the binning task completion information is sent to the control terminal 103.

The intelligent warehouse among the production processes receives the warehouse-in task issued by the control terminal, and the controller conveys the materials produced by the previous production process to the corresponding cache line for caching according to the material types by controlling the first conveying line arranged at the outlet of the previous production process and at least two cache lines arranged between the first conveying line and the inlet of the next production process. Because the buffer line is connected with the inlet of the next production process, when the material on the corresponding buffer line is required to be used for production activities, the required material can be directly obtained from the corresponding buffer line, so that the buffer line is more suitable for the buffer of semi-finished products, the distance from the outlet of the previous production process to the inlet of the next production process is greatly reduced, the transportation time cost in the production process is reduced, and the production efficiency is improved.

In one embodiment, as shown in fig. 3, the intelligent warehouse between production processes further includes:

the second transporting line 203 is a transporting bus for the materials to be discharged, and the second transporting line 203 is parallel to the first transporting line 201 in the setting direction and is all set in the first direction. It will be appreciated that the direction of transport of the second transport line 203 is dependent upon the relative position of the cache line 202 and the subsequent process inlet 105, as the application is not limited in this regard. In the present embodiment, the transporting direction of the second transporting line 203 is opposite to the direction of the first transporting line 201 as indicated by an arrow in the figure.

The controller 102 also receives a first delivery task issued by the control terminal 103, where the first delivery task includes delivery materials required by the next production process and a target delivery cache line where the delivery materials are located, and the controller 102 controls the movement of the target delivery cache line and the second transport line according to the first delivery task, so as to transport the delivery materials to the next production process inlet 105.

The first ex-warehouse task is generated by the control terminal 103 according to the ex-warehouse material and the target ex-warehouse cache line where the ex-warehouse material is located. It can be understood that the warehouse-out material is a semi-finished product material required to be used in the next production process.

Specifically, in the next production process, the materials are called according to production requirements, the control terminal 103 determines the materials to be delivered and a target delivery cache line where the materials to be delivered are located according to the material codes corresponding to the materials to be delivered, and generates the first delivery task according to the materials to be delivered and the target delivery cache line where the materials to be delivered are located. And issues the first job to the controller 102. After the controller 102 receives the first delivery task issued by the control terminal 103, the controller 102 controls the target delivery buffer line to move, and delivers the delivery material to the second delivery line 203, and the controller 102 continues to control the second delivery line 203 to move, so as to deliver the delivery material to the next production process inlet 105.

The controller 102 generates corresponding reverse job completion information according to the job of leaving the warehouse, and sends the reverse job completion information to the control terminal 103.

The information of the completion of the delivery task is determined according to delivery materials. Specifically, the outgoing materials have corresponding material codes, the controller 102 controls the target outgoing buffer line and the second transport line 203 to move, after the outgoing materials are transferred to the next production process inlet 105, outgoing task completion information is generated according to the material codes corresponding to the outgoing materials, and the outgoing task completion information is sent to the control terminal 103. The control terminal 103 can determine that the ex-warehouse materials corresponding to the material codes are ex-warehouse completed according to the returned ex-warehouse task completion information, so that overall planning management is facilitated.

In one embodiment, the job of leaving the warehouse may further include a job number of leaving the warehouse, where the job number of leaving the warehouse corresponds to the code of the material of leaving the warehouse and the target cache line of leaving the warehouse one by one, and after the controller 103 completes the job of leaving the warehouse, the job completion information of leaving the warehouse is generated according to the job number of leaving the warehouse, and the job completion information of leaving the warehouse is sent to the control terminal 103.

According to the intelligent warehouse among the production processes, the controller controls the target warehouse-out cache line and the second transportation line to move by receiving the warehouse-out task issued by the control terminal, and the warehouse-out materials are transported to the inlet of the next production process, so that the problems of material caching and distribution are solved by the line body bearing between the front and rear processing processes, the two originally separated processes are connected into one continuous processing process, and the warehouse-in, cache and warehouse-out integrated control among the upper and lower processing processes is realized.

In one embodiment, as shown in fig. 4, the intelligent warehouse 100 between production processes further includes:

A diverter 204, the diverter 204 being disposed at the intersection of each transport line and each cache line;

The diverter 204 is a device that changes the direction of the transported material. Specifically, the diverter 204 is disposed at the intersection of each transport line and each cache line, and when the transport direction of the transported material needs to be changed, the controller 102 controls the driving device of the diverter 204 to change the transport direction of the transported material to be consistent with the transport direction of the target transport line or the target cache line.

Wherein, when the material is transported, the identification labels corresponding to the material codes one by one are configured. When the materials are transported to each intersection, the identification device 205 identifies the identification tag corresponding to the material, and the identification result is returned to the controller 102. It will be appreciated that the identification tag may be provided on the transported material or on a device carrying the transported material. The identification tag may be a bar code or a two-dimensional code, which is not limited in the present application. The identification device 205 is a device that can identify an identification tag and return the identification result to the controller 102. The identification device 205 and the controller 102 may be communicatively coupled via a network.

Specifically, after receiving the warehousing task issued by the control terminal 103, the controller 102 controls the first transportation line 201 to move, and when the first transportation line 201 transports the warehousing material to the intersection with each cache line 202, the identification device 205 arranged at each intersection identifies the identification tag corresponding to the warehousing material, so as to obtain a corresponding identification result, wherein the identification result comprises the identification tag of the warehousing material and the information of the cache line corresponding to the identification device; transmitting the recognition result to the controller 102;

If the matching is unsuccessful, it is determined that the warehouse-in material does not reach the corresponding target warehouse-in cache line, and the controller 102 continues to drive the first transportation line 201 to move, and transports the warehouse-in material to the next intersection for judgment.

In one embodiment, the identification tag is an identification bar code and is arranged on a tray for carrying transported materials, and the tray is composed of tooling plates. Specifically, when a pallet carrying materials is transported to an intersection, the identification device scans and identifies the identification bar code on the pallet to obtain an identification result, and sends the identification result to the controller 102.

Specifically, the outlet of the target outlet cache line is taken as the head, the material positioned at the outlet is taken as the head material, and other materials on the target outlet cache line are all non-head materials. If the non-head materials are to be called for delivery, the materials are arranged at the front end of the non-head materials, and all materials close to the delivery port head are more commonly called as inverted materials.

Taking four materials as an example, the four materials are respectively material 1, material 2, material 3 and material 4, which are sequentially arranged on the target warehouse-out cache line. The position of the material 4 is positioned at a delivery port of the target delivery cache line, so that the material 4 is the head material; if the material 2 is required to be taken out of the warehouse at this time, the material 2 is the second warehouse-out material in the second warehouse-out task, and the material 3 and the material 4 are the inverted warehouse-out materials in the second warehouse-out task.

Specifically, the control terminal 103 generates a second ex-warehouse task based on the discharging requirement of the non-head material, where the second ex-warehouse task includes a second ex-warehouse material and an inverted-warehouse material cached by the target ex-warehouse cache line. The controller 102 receives the second ex-warehouse task, controls the target ex-warehouse cache line to move, and when the second ex-warehouse material and the inverted warehouse material respectively pass through the intersection of the target ex-warehouse cache line and the second transportation line 203, the identification device 205 feeds back an identification result to the controller 102, and the controller 102 controls the corresponding steering gear to respectively change the transportation directions of the second ex-warehouse material and the inverted warehouse material to be consistent with the transportation direction of the second transportation line 203; when the second ex-warehouse material and the inverted warehouse material are transported to the intersections of the second transportation line 203 and the inverted warehouse transportation line 206, the recognition device 205 recognizes the second ex-warehouse material and the inverted warehouse material, and feeds back the recognition results to the controller 102, and if the controller 102 determines that the material at the intersections is the inverted warehouse material according to the recognition results, the steering device 204 is controlled to change the transportation direction of the inverted warehouse material to be consistent with the transportation direction of the inverted warehouse transportation line 206, and control the inverted warehouse transportation line 206 to move, so as to transport the inverted warehouse material to the inverted warehouse transportation line 206.

If the controller 102 determines that the material at the intersection is the second warehouse-out material according to the identification result, the second transportation line 203 is controlled to move continuously, and the second warehouse-out material is transported to the later production process inlet 105 for use in the later production process.

When the intelligent warehouse among the production processes in the embodiment is used, the inverted warehouse material and the required warehouse discharging material can be discharged simultaneously when the non-head material warehouse discharging is required to be taken for processing the next production process, the controller is used for conveying the inverted warehouse material to the inverted warehouse conveying line by controlling the second conveying line and the inverted warehouse conveying line, and then controlling the second conveying line to continuously move so as to convey the required non-head warehouse discharging material to the inlet of the next production process for the next production process. The intelligent warehouse in the embodiment can automatically finish the ex-warehouse work of the non-head materials, and effectively avoids the occurrence of the condition that the whole ex-warehouse process is disturbed because the non-head materials cannot be ex-warehouse.

In one embodiment, as shown in fig. 7, the intelligent warehouse 100 between production processes further includes:

A spare cache line 207 disposed between the first transport line 201 and the second transport line 203; the spare cache line 207 is parallel to the cache line 202 and is adjacent to the inverted storage transport line 206 in the transport direction of the first transport line 201;

When the inverted warehouse material reaches the intersection of the inverted warehouse conveying line 206 and the first conveying line 201, the controller 102 controls the diverter 204 to change the conveying direction of the inverted warehouse material to be consistent with the conveying direction of the first conveying line 201, and conveys the inverted warehouse material to the first conveying line 201;

The controller 102 controls the first transportation line 201 to move, when determining that the inverted warehouse material reaches an intersection between the standby cache line 207 and the first transportation line 201 according to the identification result of the identification device 205, the controller 102 controls the first transportation line 201 to be suspended and communicates with the control terminal 103, when acquiring a steering instruction issued by the control terminal 103, the controller 204 is controlled to change the transportation direction of the inverted warehouse material to be consistent with the transportation direction of the standby cache line 207, and the controller 102 controls the standby cache line 207 to move and transport the inverted warehouse material to the standby cache line 207 for caching; the steering instruction is issued when the control terminal 103 determines that the target outgoing cache line is full, or the storage type of the target outgoing cache line changes.

Wherein the spare cache line 207 is a removable carrier line for caching the inverted stock.

Specifically, the controller 102 controls the movement of the inverted warehouse conveying line 206, conveys the inverted warehouse material located on the inverted warehouse conveying line 206 to the intersection of the inverted warehouse conveying line 206 and the first conveying line 201, and controls the corresponding diverter 204 to change the conveying direction of the inverted warehouse material to be consistent with the first conveying line 201 according to the identification result transmitted by the identification device 205;

When the controller determines that the inverted materials arrive at the intersection of the standby buffer line 207 and the first transport line 201 according to the identification result of the identification device 205, the first transport line 201 is controlled to be suspended, and the controller communicates with the control terminal 103 to send information about whether the inverted materials are put in storage or not to the control terminal 103; the control terminal 103 determines whether the target outgoing cache line originally caching the inverted material can accommodate the inverted material reflow cache according to the information transmitted by the controller 102. If the target out-of-warehouse cache line is occupied by other newly-warehoused materials when the out-warehouse material is subjected to the out-warehouse operation, so that the cache capacity of the target out-warehouse cache line is full, or the material code type of the stored material of the target out-warehouse cache line is changed compared with that of the out-warehouse material, the control terminal 103 issues a steering instruction, the controller 102 receives the steering instruction, controls the steering device 204 to change the transportation direction of the out-warehouse material to be consistent with the transportation direction of the standby cache line 207, and then controls the standby cache line 207 to move, so that the out-warehouse material is transported to the standby cache line 207 for caching. The latter process entry calls for material that is preferentially consumed in the spare cache line 207.

In this embodiment, when it is determined that the target outgoing cache line originally caching the inverted warehouse material cannot accommodate the inverted warehouse material backflow cache, the inverted warehouse material is cached to the standby cache line, and the cache material on the standby cache line is preferentially consumed when the next time of material calling, so that the inverted warehouse material can be processed according to the specification, the occurrence of the condition that the inverted warehouse material blindly enters the cache to cause the disorder of the types of the cache material on each cache line in the intelligent warehouse is avoided, the intelligent warehouse is facilitated to continuously and automatically carry out the warehouse entering and exiting task according to the preset rule, and the material transportation efficiency between two working procedures is improved.

In one embodiment, when the controller 102 does not receive the steering instruction within a preset time, the controller controls the first transportation line 201 to move continuously, and when the inverted material reaches the intersection of the target outgoing cache line and the first transportation line 201, the controller controls the steering device 204 to change the transportation direction of the inverted material to be consistent with the transportation direction of the target outgoing cache line, controls the target outgoing cache line to move, and transports the inverted material to the target outgoing cache line for caching.

Specifically, if the control terminal 103 determines that the target outgoing cache line that originally caches the inverted material can accommodate the inverted material reflow cache, no steering instruction is issued. When the controller 102 does not receive the steering instruction within the preset time, the first transportation line 201 is controlled to continue moving, and when the controller determines that the inverted warehouse material reaches the intersection of the first transportation line 201 and the target warehouse-out cache line according to the identification result returned by the identification device 205, the steering device 204 is controlled to change the transportation direction of the inverted warehouse material to be consistent with the target warehouse-out cache line, and the inverted warehouse material is transported to the target warehouse-out cache line for caching. It will be appreciated that the specific value of the preset time may be dependent on the actual situation.

The intelligent warehouse among the production processes in the embodiment first determines whether the target outgoing cache line originally caching the inverted material can accommodate the inverted material reflow cache, and then determines whether to cache the inverted material to the standby cache line or the target outgoing cache line. By using the intelligent warehouse in the embodiment, the inverted warehouse materials can be processed more normally, the condition that the inverted warehouse materials are blindly cached in a warehouse to cause the disorder of the types of the cached materials on each cache line in the intelligent warehouse is avoided, the intelligent warehouse is facilitated to automatically carry out the warehouse-in and warehouse-out tasks according to the preset rules, and the material transportation efficiency between two working procedures is improved.

In one embodiment, if the control terminal 103 determines that the target outgoing cache line originally storing the inverted material can accommodate the inverted material reflow cache, the control terminal sends a reflow task to the controller 102, where the reflow task includes the inverted material and the target outgoing cache line. After the controller 102 receives the reflow task, the first transportation line 201 is controlled to continue moving, and when the controller determines that the inverted warehouse material reaches the intersection of the first transportation line 201 and the target warehouse-out cache line according to the identification result returned by the identification device 205, the steering device 204 is controlled to change the transportation direction of the inverted warehouse material to be consistent with the target warehouse-out cache line, so that the inverted warehouse material is transported to the target warehouse-out cache line for caching.

In one embodiment, the spare cache line may also cache binned material whose bin code is inconsistent with the bin codes of all of the materials in the current cache line 202.

In one embodiment, when the controller 102 determines that the inverted materials arrive at the intersection of the standby buffer line 207 and the first transport line 201 according to the identification result of the identification device 205, the first transport line 201 is controlled to be suspended, and the information about whether the inverted materials are put in storage is communicated with the control terminal 103 like the control terminal 103; the control terminal 103 determines whether the inverted materials can be accommodated in the storage buffer on each buffer line 202 according to the information transmitted by the controller 102. If the buffer capacity of each buffer line 202 is full, or the material code types of the buffer materials on each buffer line 202 are different from those of the inverted stock materials, the control terminal 103 issues a steering instruction, the controller 102 receives the steering instruction, controls the steering 204 to change the transportation direction of the inverted stock materials to be consistent with the transportation direction of the standby buffer line 207, and then controls the standby buffer line 207 to move so as to transport the inverted stock materials to the standby buffer line 207 for buffering. The latter process entry calls for material that is preferentially consumed in the spare cache line 207.

If the control terminal 103 determines that the warehouse has the cache line 202 in the warehouse and can accommodate the warehouse-in and warehouse-out material, generating a second warehouse-in task according to a preset warehouse-in rule, and sending the second warehouse-in task to the controller 102, wherein the second warehouse-in task comprises the warehouse-out material and the warehouse-out target cache line. The method comprises the steps of storing a target cache line in a storage, wherein the target cache line is generated according to a preset storage rule and a material code of a storage-poured material during storage-pouring.

After the controller 102 receives the second warehouse-in task, the first transportation line 201 is controlled to continue moving, and when the controller determines that the warehouse-down material reaches the intersection of the first transportation line 201 and the warehouse-down target cache line according to the identification result returned by the identification device 205, the steering device 204 is controlled to change the transportation direction of the warehouse-down material to be consistent with the warehouse-down target cache line, so that the warehouse-down material is transported to the warehouse-down target cache line for caching.

In one embodiment, the controller 102 receives a current ex-warehouse material position determining instruction issued by the control terminal 103, controls the identifying device 205 to identify a current ex-warehouse material running on the second transportation line 203 according to the current ex-warehouse material position determining instruction, generates current real-time position information of the ex-warehouse material according to the identification result, and sends the current real-time position information of the ex-warehouse material to the control terminal 103; the command for determining the current delivery material position is issued when the control terminal determines that a delivery task currently exists and a new delivery task needs to be issued.

Specifically, when the control terminal 103 does not receive the task completion information of the completion of the last ex-warehouse task returned by the controller 102 within a preset time, if a new ex-warehouse task needs to be issued, the real-time position information of the current ex-warehouse material is determined. The control terminal 103 generates a current ex-warehouse material position information determining instruction according to the material code of the current ex-warehouse material, and issues the current ex-warehouse material position information determining instruction to the controller 102, the controller 102 invokes the recognition result of each recognition device 205, determines the real-time position information of the current ex-warehouse material, and returns the real-time position information of the current ex-warehouse material to the control terminal 103, and the control terminal 103 determines whether the current unfinished ex-warehouse task collides with the ex-warehouse task to be issued according to the real-time position information of the current ex-warehouse material, if the current ex-warehouse material just blocks the ex-warehouse material outlet corresponding to the ex-warehouse task to be issued, at this moment, if the current ex-warehouse material is forcibly ex-warehouse, the two collide, and the material transportation safety is not facilitated. If issuing a plurality of ex-warehouse tasks does not conflict, issuing a new ex-warehouse task to the controller 102; if a conflict occurs in the issuing of the plurality of ex-warehouse tasks, the issuing of a new ex-warehouse task is suspended, and after a preset time, an instruction for determining the position information of the current ex-warehouse materials is issued again to the controller 102, and whether the plurality of ex-warehouse tasks conflict is continuously judged.

The intelligent warehouse in the embodiment determines whether to issue a new delivery task or not by judging the real-time position information of the current delivery material in advance, so that the situation that a plurality of delivery tasks conflict can be well avoided, and the safety of material transportation is ensured.

In one embodiment, if the control terminal 103 determines that the issuing of multiple outbound tasks may collide, the issuing of a new outbound task is suspended until receiving the current outbound task completion information returned by the controller 102, and then the issuing of the new outbound task is performed.

In one embodiment, the intelligent warehouse for production process components may further include warehousing from a plurality of prior production process outlets and a plurality of subsequent production process outlets. As shown in fig. 8, the outlets of the previous production processes are respectively connected with the first conveying line through feeding input lines, and the inlets of the next production processes are respectively connected with the second conveying line through discharging conveying lines. The diverter is arranged at the intersection of each line, and the identification device is respectively arranged at the intersection of each feeding conveying line and the first conveying line. In this embodiment, the previous production process outlet corresponds to a material cache line, and the material codes of the materials produced by the previous production process outlet belong to the same category, and the corresponding cache line preferentially stores the materials produced by the previous production process outlet, so that the material corresponding to the material code is preferentially stored in the one cache line. It can be understood that if a special situation occurs, such as that the material buffer line corresponding to the previous production process outlet is full, at this time, if the other production process outlets are not in a working stage, that is, the buffer line corresponding to the other production process outlets is in an idle stage, at this time, each transport line and each buffer line can be controlled to transport the material to be buffered to the idle buffer line for buffering. If the idle buffer line is located above the outlet of the previous production process, the material to be buffered produced by the outlet of the previous process needs to cooperate with the inverted storage transport line through the third transport line at the lowest part in the figure, and the material to be buffered is inverted storage and transported to the corresponding idle buffer line for buffering. And if the warehouse does not have an idle cache line, transporting the material to be cached to the standby cache line for caching through the cooperation of the third transport line and the inverted warehouse transport line. The working principles of the identification device and the steering device are the same as those of the identification device and the steering device in the above embodiments, and are not described herein. It should be understood that in this embodiment, the materials to be cached may be transported to any cache line for caching through each cache line and transport line, and may also be transported from each previous production process outlet to each subsequent production process outlet.

In one embodiment, there is provided an intelligent warehouse between production processes, comprising: a dispatch system, a manufacturing execution system, a warehouse management system, a controller, and a production transportation device. The controller is a PLC controller and is electrically connected with a driving motor of each transport line in the production and transport device and a buffer line for materials. The dispatch system is operated on the terminal equipment of the production personnel and connected with the manufacturing execution system through a network. The manufacturing execution system is an MES system, and production plans corresponding to all working procedures and material information of materials required in the production plans, such as material codes, material names, material quantity, material output machine numbers, material use machine numbers and the like are stored in the system. The warehouse management system is a WMS/WCS system and is in communication connection with the MES system through a network.

The production and transportation device comprises a former production process outlet, a latter production process inlet, each transportation line for transportation and a buffer line for materials, and a diverter and identification equipment arranged at the intersection of each transportation line and the buffer line.

Taking the business flow of the warehouse entry system shown in fig. 9 as an example, how the intelligent warehouse among the production processes executes the warehouse entry task will be described:

After the processing of the materials to be transported by the production personnel in the previous production process is completed, the materials are submitted to completion in the dispatching system, and the submitted completion information comprises, but is not limited to, the name of the materials in the dispatching system, the quantity of the materials, the number of the materials output machine, the tray codes corresponding to the materials and the like. Simultaneously, a handheld code scanner is used for binding the tray codes bearing the materials to be transported with the materials. The dispatch system sends the finished report information to the MES system, and the handheld code scanner sends the tray number bound with the materials to the MES system.

And the MES system generates material information according to the received finished information and the tray number corresponding to the material, and transmits the material information to the WMS/WCS system through the API interface. The material information comprises material names, material codes, quantity, machine numbers, tray numbers and the like. The material codes are in one-to-one correspondence with the semi-finished materials to be put in storage.

Wherein, the API interface is encapsulated with a preset warehousing rule. The preset warehousing rules are as follows:

Fourth, when the warehouse is needed to be reversed, the same coded materials are stored in the same cache line, and the materials coded by different materials are placed in the standby cache line.

Specifically, when the MES issues material information through the API, the material information triggers a preset warehousing rule packaged by the standard interface, and the WMS/WCS system generates a corresponding warehousing task according to the preset warehousing rule and the material information. And sending the warehousing task to the PLC. The warehousing tasks comprise warehousing task numbers, material codes corresponding to warehousing materials, target warehousing cache lines corresponding to the warehousing materials and target warehousing warehouse positions.

The PLC receives the warehousing tasks, controls each transportation line and each cache line of the production transportation device to execute the warehousing tasks according to the warehousing tasks, identifies the tray codes of the trays carrying the warehousing materials through the code scanner arranged at each intersection when the warehousing materials are transported to the intersection of each transportation line and each cache line, judges whether the warehousing materials need to be turned at the position according to the identification information, and controls the jacking transplanting device arranged at each intersection to jack up if the warehousing materials need to be turned at the position, changes the transportation direction of the warehousing materials, and transports the warehousing materials to the target warehousing cache line for caching. When the PLC controls the movement of the target warehouse-in cache line to transport warehouse-in materials to the target warehouse-in position, the PLC generates corresponding task completion information and sends the task completion information to the WMS/WCS system to report completion.

Taking the general business flow of the ex-warehouse system shown in fig. 10 as an example, how the intelligent warehouse between production processes performs the general ex-warehouse task will be described:

and the MES system sends out library material information to the WMS/WCS system through the API interface according to the production plan or the material calling request received by the system and put in the warehouse in the next process. And the WMS/WCS system produces corresponding ex-warehouse tasks according to the ex-warehouse material information. The ex-warehouse task comprises an ex-warehouse task number, a material code corresponding to the ex-warehouse material, a target ex-warehouse cache line corresponding to the ex-warehouse material and a target ex-warehouse position.

Before issuing a warehouse task, the WMS/WCS system firstly judges whether an unfinished warehouse-out task exists at present, if so, firstly judges a target warehouse-out cache line of the current warehouse-out material, and if the target warehouse-out cache line is the cache line closest to the entrance of the next procedure, immediately issuing the warehouse-out task; if the target ex-warehouse cache line of the current ex-warehouse material is not the cache line closest to the inlet of the next process, a warehouse request is sent to the PLC, the PLC reads the photoelectric signals of the code scanner of the ex-warehouse port of each cache line according to the received ex-warehouse request, determines the real-time position of the current ex-warehouse material according to the photoelectric signals, and feeds back the real-time position of the current ex-warehouse material to the WMS/WCS system. The WMS/WCS system determines whether the outlet of the target outlet cache line of the next outlet task is occupied according to the real-time position of the current outlet material, if not, the outlet task is immediately issued, and if so, the outlet task is suspended within a certain preset time. After the preset time, returning to execute the step of sending the library request. It can be appreciated that the preset time may be set according to the actual situation.

The PLC system controls each transport line and each buffer line of the production transport device according to the delivery task issued by the WMS/WCS system to execute the delivery task, and when delivery materials are delivered to intersections of the target delivery buffer line and the transport line, the jacking transplanting devices arranged at the intersections are controlled to jack up, the delivery direction of the delivery materials is changed, and the delivery materials are delivered to the inlet of the next production process. When the PLC controls the movement of the conveying line to convey the warehouse-out materials to the inlet of the next production process, the PLC generates corresponding task completion information and sends the task completion information to the WMS/WCS system for completion reporting.

Taking the business flow of the reverse library system shown in fig. 11 as an example, how the intelligent warehouse between production processes executes the reverse library task will be described:

The WMS/WCS system receives the ex-warehouse material information issued by the MES system, judges whether the material needing to be ex-warehouse is positioned at the ex-warehouse port of the target ex-warehouse cache line according to the ex-warehouse material information, and if the material needing to be ex-warehouse is not positioned at the ex-warehouse port of the target ex-warehouse cache line, generates an ex-warehouse task and a plurality of reverse-warehouse tasks. The ex-warehouse task comprises an ex-warehouse task number, a material code corresponding to the ex-warehouse material, a target ex-warehouse cache line and a target ex-warehouse position; the warehouse-down task comprises a warehouse-down task number, a material code corresponding to the warehouse-down material, a target warehouse-out cache line, a target warehouse-out position and a warehouse-down transportation line. And sending one ex-warehouse task and a plurality of reverse-warehouse tasks to the PLC.

And the PLC controls each transportation line and the target ex-warehouse cache line to execute corresponding tasks according to one ex-warehouse task and a plurality of inverse warehouse tasks. Specifically, when the inverted warehouse material enters the transportation main line, when the inverted warehouse material reaches an intersection of the transportation main line and the inverted warehouse transportation line, the PLC controls the jacking transplanting equipment to change the transportation direction of the inverted warehouse material to be consistent with the inverted warehouse transportation line according to the identification result of the code scanner, the inverted warehouse material is transported into the inverted warehouse transportation line, and the warehouse material is transported to the next production procedure inlet through the transportation main line, so that the warehouse discharging task is completed.

And the PLC controls the inverted warehouse conveying line to convey the inverted warehouse materials to the warehouse conveying main line, then the PLC communicates with the WMS/WCS system, the warehouse-in position of the inverted warehouse materials is determined according to a preset warehouse-in rule, and the PLC controls the warehouse-in conveying main line and the target warehouse-in buffer line to convey the inverted warehouse materials to the target warehouse-in position according to the target warehouse-in position of the inverted warehouse materials, so that the inverted warehouse task is completed.

And finally, the PLC controller generates a plurality of task completion information according to one ex-warehouse task and a plurality of reverse-warehouse tasks, and returns the plurality of task completion information to the WMS/WCS system.

It should be understood that, although the steps in the flowcharts related to the embodiments described above are sequentially shown as indicated by arrows, these steps are not necessarily sequentially performed in the order indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in the flowcharts described in the above embodiments may include a plurality of steps or a plurality of stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of the steps or stages is not necessarily performed sequentially, but may be performed alternately or alternately with at least some of the other steps or stages.
