Description

  The present invention relates to a hermetic lid opening device, and more particularly to a hermetic container lid opening device containing a harmful substance, and a transfer device.

  Hazardous substances such as waste asbestos are filled in a sealed container and transported to a low-temperature melting treatment apparatus (for example, see Patent Document 1 below). The problem is that the surrounding atmosphere is contaminated when a harmful substance is introduced.

  In order to solve such problems, conventionally, a clean room in which a vacuum pump, an inert gas cylinder, a dust collector, and a disinfecting device are connected via a pipe is formed in a sealed space partitioned by a cover. There is a technique (see, for example, Patent Document 2 below) in which the contents are transferred to a sealed container by inserting a hand, and when the sealed container containing the granular material is put into the container from the hopper, the dust hopper is moved to the container. In order to prevent backflow of the hopper portion, the outer tube portion is provided so as to surround the tubular portion continuous from the inlet of the hopper portion with a predetermined interval from the upper end to the lower end thereof. There is a technique (for example, Patent Document 3 below) for forming a connection port of a suction dust collecting apparatus around.

  However, in the method described in Patent Document 2, contamination of the surface of the lid is unavoidable, and in the method described in Patent Document 3, there is a strong possibility that harmful substances are scattered when the lid is opened and closed. .

  The present invention has been made in view of the above circumstances, and a sealed container in which the surface of the lid is not contaminated even when the lid is opened and closed in a sealed space, and contamination of the surrounding atmosphere when the lid is opened and closed can be avoided. An object is to provide a lid opening device and a transfer device.

In order to solve the above problems, the closed container opening device according to the present invention is such that the entire lower surface of the sealing part that seals the opening of the container body is sealed inside the container body, and the lower surface of the peripheral part is the opening of the container body. An opening device for a closed container having a lid that is in close contact with the end face of the side, the open space having a relative medium pressure (regardless of whether the outer edge is clear or unclear), and the closed space having a relatively low pressure; In addition, a partition wall that partitions both sides is provided.
Here, the relative intermediate pressure or the relative low pressure expresses a relative level in the relationship between the open space and the closed space. Based on this, for example, the relative intermediate pressure is an atmospheric pressure that is open to the outside world and equivalent to the atmospheric pressure, and the relative low pressure is an atmospheric pressure that is separated from the outside world and adjusted to be lower than the atmospheric pressure of the open space. is there.

The partition includes a through hole through which the lid passes and surrounds the peripheral edge of the opening of the container body, and a guide surface that faces the through hole and is close to the side surface of the peripheral edge of the opening of the container main body.
The closed space includes a lid opening / closing means, and the lid opening / closing means includes a lid holder for holding the lid and a driving means for causing the lid holder to open and close.
The lid holder includes a holding space that covers the side and surface of the lid peripheral edge and the surface of the sealing portion, and a fixing unit that draws the lid to the holding space.

  As described above, the present invention has the property of avoiding contamination of the open space by utilizing the pressure difference between the closed space and the open space, but even in the guide surface, a relative high pressure is present in the vicinity of the guide surface. By providing the boundary pressure adjusting means for supplying air at the lid holder, the reliability thereof is improved, and even in the lid holder, the holding space is provided with the holding pressure adjusting means for supplying air at a relatively high pressure to contaminate the holding space. Is avoiding. Here, the relative high pressure expresses the relative level of the atmospheric pressure in the closed space, the open space, the vicinity of the guide surface, and the holding space in relation to the relative low pressure and the relative intermediate pressure. Thus, the relative high pressure represents an atmospheric pressure that is equal to or higher than the atmospheric pressure that is the relative intermediate pressure.

  That is, the relative intermediate pressure for the open space, the relative low pressure for the closed space, the relative high pressure for the vicinity of the guide surface, and the relative high pressure for the holding space are respectively used to block the airflow at the boundary between the open space and the closed space. Because the action of urging the airflow toward the closed space at the boundary between the holding space and the closed space is generated at the boundary between the guide surface and the closed space. This is a relative requirement for the atmospheric pressure. In addition, although the vicinity of the guide surface is set to a relative high pressure, an air flow from the air supply port of the guide surface to the open space is also generated, but the air flow from the air supply port to the closed space is generated even in consideration of the presence of the air flow. It can be said that this is a very advantageous measure in terms of enhancing the effect of containing harmful substances in the enclosed space (see FIGS. 4 to 6).

If the said airtight container opening apparatus is used, the transfer apparatus of a pollutant etc. can be comprised easily.
For example, as a first transfer device according to the present invention, a container loading means for sending the peripheral edge of the opening of the sealed container to the through hole is provided in the open space, and a supply means for putting the contents into the sealed container in the closed space. The supply means can realize a transfer device to a sealed container having a configuration including a supply port that is in close contact with or loosely fitted to the inner surface of the peripheral edge of the opening of the sealed container when the contents are charged.

  In addition, as a second transfer device, a closed space is provided with a receiving device for receiving the contents of the charged sealed container, and the open space is sealed so that the contents are dropped with the opening facing the receiving device. A container tilting means for tilting the container, wherein the partition wall is an airtight sheet and a guide ring fixed to a part of the airtight sheet so that the connection portion is in an airtight state, A guide ring includes the through-hole, and a guide surface that faces the through-hole and is close to a side surface of the peripheral edge of the opening of the container body, and the container tilting means is provided on the guide ring and the guide ring. It is also possible to employ a transfer device comprising a support frame for fixing the sealed container and tilting means for tilting the guide ring and the support frame.

  As described above, according to the closed container opening device and the transfer device according to the present invention, it is possible to avoid contamination of the surface and side surfaces of the lid in contact with the outside air even when the lid is opened and closed in the sealed space. Contamination of the outside of the closed space, the surrounding atmosphere, and the surface of the sealed container that comes into contact with the outside air due to scattering or dropping of harmful substances during opening and closing of the container is avoided.

Hereinafter, an airtight container opening device (hereinafter referred to as an opening device) according to the present invention and a transfer device using the device will be specifically described with reference to the drawings.
The lid opening device according to the present invention is used to open a closed container shown in FIG.
The closed container is a drum having a bottomed cylindrical container body 2 and a lid 1 for sealing the opening. The airtight container is appropriately provided with a lid opening prevention means such as a lock band 9 in order to maintain the airtight state.

  The container body 2 in this example has a bottomed cylindrical shape, and includes a rim portion that can maintain an airtight state with the peripheral edge portion 1 b of the lid 1 at the peripheral edge of the opening peripheral edge portion 2 a. By adopting such a structure, it is convenient for the contents to be prevented from being scattered outside the container and to be placed on the pallet and stacked with the same type of sealed container.

  The lid 1 includes a sealing portion 1a that seals the opening of the container main body 2, and a peripheral portion 1b that is placed on the end surface on the opening side of the container main body 2 and slightly covers the opening peripheral portion 2a.

  With the above configuration, the lower surface of the peripheral edge portion 1b of the lid 1 is in close contact with the end surface on the opening side of the container body 2 in an airtight state, and the entire lower surface of the sealing portion 1a existing inside the lower surface of the peripheral edge portion 1b is the container. It will be enclosed inside the main body 2.

  In such a closed container, because of its use and structure, it is unavoidable that the inside of the peripheral edge portion 1b of the lid 1 and the entire lower surface of the sealed portion 1a are exposed to the contaminated area (inside the closed container). In the contaminated space, by adopting a structure that covers the outside of the region where the contamination is unavoidable, contamination of the surface of the lid 1 exposed to the outside air can be substantially avoided. Further, by adopting a structure that avoids contamination of the surface of the container main body 2 other than the opening that is in contact with the peripheral edge 1b of the lid 1, it is possible to avoid substantially the entire area of the surface of the sealed container exposed to the outside air from contamination. It becomes.

For the above purpose, the lid opening device shown in FIGS. 1 to 6 has the basic structure required as described above, a relatively medium pressure open space A, a relatively low pressure closed space B, and a partition partitioning both. C is provided.
The open space A is a region under the atmospheric pressure through which the outside air circulates, and the closed space B is blocked from the outside air by an exterior (not shown), a partition wall C, etc., and becomes a pressure relatively lower than the atmospheric pressure. This is the area that was inhaled.

The partition wall C includes a through hole D that surrounds the opening peripheral portion 2 a of the container body 2 through which the lid 1 can pass, and a guide surface E that faces the through hole D and is close to the side surface of the container body 2.
In the lid opening device shown in FIGS. 1 to 6, a fixed partition wall C is set horizontally at a fixed position, and a guide surface E having a width that does not cause the flow of airflow from the open space A to the closed space B is provided.

  The lid opening device includes container loading means 4 for feeding the opening peripheral edge 2a of the sealed container to the through hole D in the open space A, and lid opening / closing means 3 in the closed space B (FIGS. 1 and 4). To FIG. 6).

  The container loading means 4 holds the sealed container upright in the penetrating direction of the through hole D, and seals it from the set position (or the directly facing position) directly below the through hole D in the open space A before opening the lid. Elevating means for raising the container until only the lid 1 is exposed from the surface of the partition wall C on the closed space B side (hereinafter referred to as a contaminated surface) (in this example, means for moving up and down the stage 4a on which the sealed container is placed) However, a known technique may be used as appropriate.).

The lid opening / closing means 3 includes a lid holder 3a that holds the lid 1 and driving means (not shown) that causes the lid holder 3a to open and close.
The lid holder 3a includes a holding space 3b in which the lid is accommodated, and a fixing unit 3c that draws the lid 1 to the holding space 3b. The holding space 3b has an area and a depth that can cover the side surface and surface of the peripheral edge portion 1b and the surface of the sealing portion 1a of the lid 1 that has been drawn.
In this way, the lid holder 3a in this example has an opening in which the lid 1 is loosely fitted, and the lid 1 of the sealed container raised by the container loading means 4 is closed in the through hole D in a part of the lid opening operation. A position to be captured on the space B side (hereinafter referred to as a capture position) is taken.

The fixing unit 3c in this example includes an adsorption plate 3e that uniformly supports the suction cup 3f that is adsorbed to the blocking portion 1a of the lid 1, and a cylinder that advances and retracts the adsorption plate 3e.
The cylinder is fixed at the center of the lid holder 3a so that the rod 3g is sealed in the holding space 3b, and the rod 3g of the cylinder moves forward and backward with respect to the opening of the lid holder 3a inside the holding space 3b. It is fixed.
In addition, when it has a hook and a ring on the surface of the sealing part 1a of the lid | cover 1, you may fix a ring and a hook to the front-end | tip of the rod 3g instead of the suction cup 3f.

In this example, the lid holder 3a is provided with holding pressure adjusting means 3d that makes the holding space 3b a relatively high pressure.
The holding pressure adjusting means 3d in this example connects an air supply pipe to the holding space 3b, reads the internal pressure of the holding space 3b, and adjusts the air supply amount to adjust the inside of the holding space 3b to a predetermined relative high pressure (closed). The atmospheric pressure is higher than the atmospheric pressure).

  The driving means is configured to include an actuator that supports the lid holder 3a and controls the lid holder 3a to move back and forth from the capture position to a retracted position that does not interfere with the subsequent operation.

  As shown in FIG. 1, the lid opening device configured as described above includes a carrying-in process for carrying a sealed container directly under the through hole D and fixing it to the stage 4 a of the container loading means 4, and a suction plate 3 e of the fixing means 3 c. Fixing step of lowering the suction cup 3f against the sealing portion 1a of the lid 1 and adsorbing it, removing the lock band 9 connecting the lid 1 and the container body 2 while preventing the lid 1 from lifting up, and removing the peripheral edge of the opening of the container body 2 The unlocking process of lowering from 2a, the loading process of raising the stage 4a and holding the sealed container together with the suction plate 3e until only the lid 1 is exposed from the surface of the partition wall C on the closed space B side (FIG. 5 (A) and 6A), the lid 1 captured by the lid holder 3a is removed from the container body 2 and the lid opening process for retracting the lid holder 3a (see FIGS. 5B and 6B) is sequentially performed. Finish opening the lid.

  A lid closing step of moving the lid holder 3a that has captured the lid 1 from the retracted position to the capturing position after finishing the operation such as the transfer step in the opened state (see FIGS. 5B and 6C); A separation step of covering the through hole D of the partition wall C with the holding space 3b, and lowering the stage 4a to the open space while pressurizing the sealing portion 1a of the lid 1 with the suction cup 3f of the suction plate 3e, and connecting the lid 1 and the container body 2 Locking process of attaching the lock band 9 to the opening of the sealed container, the suction of the suction cup 3f is released and the suction plate 3e of the fixing means 3c is lifted to remove the suction cup 3f from the blocking part 1a of the lid 1, and the sealed container is removed from the stage 4a. A series of lid closing operations are completed through the unloading process.

  In the opening operation and the closing operation, the through hole D of the partition wall (guide ring C2) C is always sealed in the holding space 3b in the loading process, unlocking process, loading process, releasing process, locking process, and unloading process. In the opening process and the closing process, the through hole D of the partition wall (guide ring C2) C is always sealed by the opening peripheral part 2a of the container body 2 except for the clearance of the peripheral part (see FIG. 4 (B), FIG. 5 (B), and FIG. 6 (B)). In the gap between the guide surface E and the container body 2, by setting the open space A to a relative medium pressure and the closed space B to a relatively low pressure, an air flow from the open space A to the closed space B is generated. Inflow into the through hole D and the open space A is prevented.

  In the measures for preventing the inflow of harmful substances into the holding space 3b, the holding space 3b faces the open space A which is not contaminated in the loading process, the unlocking process, the loading process, the detaching process, the locking process and the carrying out process. In the opening step and the closing step, the lid 1 of the hermetic container is loaded and the opening of the holding space 3b is sealed except for the gap existing around the lid 1, so that the holding space 3b Contamination is avoided. At that time, the holding space 3b is maintained at a predetermined relative high pressure in the holding space 3b by adjusting the air supply amount by the holding pressure adjusting means 3d, and a gap between the side surface of the lid 1 and the inner wall of the holding space 3b. (It may be a gap generated only by air supply or pressurization) By making the holding space 3b a relative high pressure and making the closed space B a relatively low pressure, an air flow from the open space A to the closed space B is generated, Inflow of harmful substances into the holding space 3b is prevented (see FIGS. 4B, 5B, and 6B).

The lid opening device shown in FIGS. 1 to 6 further employs a structure in which a boundary pressure adjusting means F is provided on the guide surface E of the partition wall C to supply the vicinity of the guide surface E with a relatively high pressure. Here, the relative high pressure is a pressure higher than the pressure in the closed space B and higher than the pressure in the open space A.
The boundary pressure adjusting means F is provided with piping in the partition wall C, and air supply holes for discharging air at a relatively high pressure at a middle position of the guide surface E according to the width of the guide surface E.
By providing the boundary pressure adjusting means F, even if the width of the guide surface E is relatively wide, it is possible to obtain an effect that the airflow from the open space A to the closed space B is not lost (see FIG. 5). ).
Further, in combination with the air flow from the open space A to the closed space B, the inflow of harmful substances into the open space A, the adhesion of harmful substances to the side surfaces of the opening peripheral edge 2a of the container body 2, and the guide surface E Adherence of harmful substances to the can be prevented.

If the said airtight container opening apparatus is used, the content transfer apparatus which does not leak a content outside can be constructed | assembled.
The example of FIG.1 and FIG.5 shows 1st embodiment of the transfer apparatus which transfers the content X to an airtight container in the collection site | part of the content X which consists of harmful substances etc., A supply means 5 for putting the contents X into a sealed container is provided.

  The supply means 5 moves the narrowed funnel-like hopper 5b, and moves the hopper 5b to the capture position (supply position) when the contents X are charged (charging process), and the lid 1 of the closed container is A known driving means (not shown) for retracting to a position (standby position) that does not obstruct the opening process and the closing process until the opening lid holder 3a is retracted, and a known mechanism for sending the contents X into the hopper 5b Consists of transportation means (not shown).

  The hopper 5b is provided with a supply port 5a that is in close contact with or loosely fitted to the inner surface of the peripheral edge of the opening of the sealed container at the lowest position, and the supply port 5a is supplied to the hopper 5b via the transport means. An appropriate amount of the contents X is put into the sealed container through the.

  Even when the supply port 5a is inserted into the opening of the container body 2, if the air flow from the open space A to the closed space B is generated before the lid opening process is performed, the contents X are stored. Inflow of harmful substances scattered when thrown into the through hole D and the open space A is prevented. In addition, the airflow also prevents stagnation of scattered matter around the through hole D in the partition wall C (at least the region where the lid holder 3a and the hopper 5b are in contact) (hereinafter referred to as a cleaning effect), and harmful substances are released from the through hole D. It is possible to avoid the risk of falling into the space A as a solid.

  In order to further enhance the effect of preventing harmful substances attached to the hopper 5b from dropping into the open space A from the through hole D, and to further enhance the cleaning effect, when the hopper 5b reaches the supply position, An airflow control plate 5c that causes the airflow in the vicinity to follow the surface of the partition wall C on the closed space B side (the contaminated surface) may be provided at a position close to the surface of the supply port 5a.

The example of FIG. 6 shows 2nd Embodiment of the transfer apparatus which transfers the content X from an airtight container to a collection field or a processing apparatus.
The partition wall C of the example includes an airtight sheet C1 and a guide ring C2 fixed to a part of the airtight sheet C1 in an airtight state.
In other words, the closed space B of this example is configured such that the contents X of the sealed container are placed on a part of the exterior (not shown) that covers the transfer device or the entire system including the device so that harmful substances do not go outside. For the convenience of charging, a method of forming a deformable partition wall C is adopted.

Like the partition wall C of the lid opening device, the guide ring C2 includes the through hole D as an opening portion of the partition wall C, faces the through hole D, and the side surface of the opening peripheral portion 2a of the container body 2. An adjacent guide surface E is provided.
Further, in this example, in place of the supply means 5 provided in the first embodiment, the closed space B is provided with a receiving device 6 for receiving the contents of the charged sealed container, and an opening is provided in the receiving device 6. The open space A is provided with a container tilting means 7 that tilts the sealed container so that the contents X fall and the container X falls (see FIG. 7C).

  The acceptor 6 is a receiver that can accept the contents X that have been thrown in without being missed. The acceptor 6 itself may be a container, or the acceptor 6 may function as a hopper for receiving the contents X stored in another container.

The container tilting means 7 includes the guide ring C2, a support frame 8 for fixing the sealed container to the guide ring C2, and a tilting means 7b for tilting the guide ring C2 and the support frame 8.
The support frame 8 is a holding frame fixed integrally with the guide ring C2, and holds the sealed container in a standing state in the penetration direction of the through hole D, and directly below the through hole D in the open space A (or A container loading device 4 that integrally raises the sealed container before opening from the position directly facing) until only the cover 1 is exposed from the contaminated surface of the partition wall C is integrally provided. In view of the operation of the container tilting means 7, for the holding frame of the support frame 8, a structure is selected that can prevent the closed container from dropping or shaking even when the container tilting means 7 is tilted.

  The tilting means 7b of the container tilting means 7 fixes one end of a swivel arm 7a that swivels vertically along a horizontal axis to the guide ring C2, and the guide ring C2 and the support frame as the swivel arm 7a rotates. 8 and the closed containers supported by them are pivoted together.

  The rotation range of the swivel arm 7a is such that at least the sealed container loaded in the through hole D of the guide ring C2 from the state where the guide ring C2 is horizontal (hereinafter referred to as a set angle; see FIG. 6B). The opening is directed to the receiving device 6 and is in a range up to an inclination (hereinafter referred to as a charging angle, see FIG. 6C) to which all the contents X fall.

  The structure of the lid opening / closing means 3 in this example is the same as that of the lid opening device described above, but in this example, the inclination of the support frame 8 by the container tilting means 7 is used to reach the closing angle from the set angle. A structure in which the opening of the lid 1 of the hermetic container automatically increases as the inclination increases, and automatically decreases until the opening of the lid 1 of the hermetic container is fully closed (set angle) as the inclination decreases. It is also good.

Even in the second embodiment, in the carry-in process, the unlocking process, the loading process, the releasing process, the locking process, and the carrying-out process, the through hole D of the partition wall (guide ring) is always sealed with the holding space 3b. In the opening process and the closing process, the through hole D of the partition wall (guide ring) is always sealed at the peripheral edge 2a of the opening 2 of the container body 2 except for the clearance at the peripheral edge (FIG. 4B ), See FIG. 6B).
Even in the gap between the guide surface E and the container body 2, by setting the open space A to a relative medium pressure and the closed space B to a relatively low pressure, an air flow from the open space A to the closed space B is generated, and harmful substances are generated. Inflow to the through hole D and the open space A is prevented (see FIGS. 4B and 6B).

Regarding the inflow of harmful substances into the holding space 3b, the holding space 3b faces the uncontaminated open space A in the carrying-in process, the unlocking process, the loading process, the releasing process, the locking process and the carrying-out process. In the opening process and the closing process, the lid 1 of the hermetic container is loaded and the holding space 3b is sealed.
Even in this example, the holding space 3b is maintained at a predetermined relative high pressure in the holding space 3b by adjusting the air supply amount by the holding pressure adjusting means 3d. In the gap between the inner walls of the space 3b (which may be a gap generated only by supply of air), the holding space 3b is set to a relatively high pressure, and the closed space B is set to a relatively low pressure, whereby the air flow from the open space A to the closed space B As a result, harmful substances are prevented from flowing into the holding space 3b (see FIGS. 4B, 6B, and 6C).

  Even in the gap between the guide surface E and the container body 2, as in the case of the lid opening device, it is possible to take measures to make the open space A a relative medium pressure and the closed space B a relatively low pressure. An air flow from the space A toward the closed space B is generated, and harmful substances are prevented from flowing into the open space A (see FIGS. 4B, 6B, and 6C).
