Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for pushing garbage into a container,
The lid of the container is removably attached to the pushing plate of the compactor, and its reciprocating motion pushes the garbage from the compactor into the container. After pushing the garbage, the lid automatically locks the garbage insertion opening of the container. The present invention relates to a device for pushing garbage into a container.

[Conventional technology]

When transporting garbage from a collection site, a compactor is installed at the collection site to push the garbage.
A transportable container is connected to it and garbage is pushed into it. An example of such a garbage pushing device is described in Japanese Patent Application Laid-Open No. 55-89103.

[Problem that the invention seeks to solve]

By the way, in an operation in which the waste insertion port of a container is closely communicated with the extrusion port of the compactor, and the waste thrown in from the hopper above the end of the compactor is pushed in by the reciprocating movement of the pushing plate inside the compactor,
When a container filled with garbage is removed from a compactor, the garbage often leaks out from the garbage inlet. In order to solve this problem, a device in which the lid of the container can be attached to and detached from the garbage insertion opening is described, for example, in Japanese Patent Publication No. 54-26116. this is,
The lid of the container can be attached to and removed from the garbage insertion port, and this lid is attached to the front of the pushing plate of the compactor, and the garbage is pushed into the container using the back of the lid, and after filling with garbage, the lid is pushed in. Position the lid together with the plate at the garbage insertion opening, fix only the lid body to the garbage insertion opening using a pin from the outside of the side of the container, and engage the hook that integrates this lid body with the push-in plate.
The insertion tip of the pin is also released.

This type of garbage pushing device requires manual work to insert and remove the pins from the outside of the container, so the pins are pulled inward using a cylinder, etc., and at the same time, the lid body is integrated with the pushing plate. A device designed to do this was developed in 1976.
It is described in Publication No. 13402. This is because a pin that moves in the left and right direction is always biased by a spring to fix the lid in the garbage insertion slot.
The connecting rod attached perpendicularly to the pin is pulled inward by the rotation of the hook provided on the push plate of the compactor, and at the same time, by engaging with the connecting rod,
The lid body and the push-in plate are integrated. In such a device, the only thing that engages the pin with the hole on the container side is the elastic force of the spring.
If dirt is caught, engagement becomes impossible and there is a problem in that the lid cannot close the container's dirt insertion opening. In addition, when the connecting rod and the hook are engaged, the connecting rod attached to the pin is secured by the contraction force of the cylinder that moves inward against the elastic force of the spring, and is pushed into the lid body. Since it is integrated with the plate, there is a problem that the engagement for integration may come off.

The present invention was made in view of the above-mentioned problems, and its purpose is to eliminate the manual work of inserting and removing pins from the outside of the container, and to automatically fix the lid body to the garbage insertion port. At that time, even if dirt gets caught, the pin will surely engage the hole on the container side and the dirt insertion opening will be closed.Furthermore, the engagement between the connecting rod and the hook will be ensured, and the lid will close. To provide a device for pushing garbage into a container, which can firmly integrate a body and a pushing plate.

[Means for solving problems]

As shown in FIG. 3, the present invention uses a reciprocating movement of a push-in plate 7 with a lid 9 integrated on the front surface to remove garbage 6.
The present invention is applied to a garbage pushing device in which the lid body 9 can be fixed to the garbage insertion opening 4 of the container 3 after pushing the lid body 9 into the container 3. Its characteristic feature is that a closing rod 25 is provided on the front surface of the lid body 9 and is movable in the left and right direction in order to insert and remove the tip into a hole 28 formed on the side of the garbage insertion port 4. A locking rod 26 extending in the vertical direction is fixed to the closing rod 25. The front surface of the push-in plate 7 has an engaging body 13 having a recessed part 13a into which the locking rod 26 is fitted and is moved in the left-right direction by the cylinder 12; The hook 14 grips the locking rod 26 fitted in the concave portion 13a, and the locking rod 26 is gripped by the engaging body 13 and the hook 14, which is rotated by contacting the hook 14 when the engaging body 13 moves. A stopper 19 is provided for releasing the lock.

[Effect]

The cylinder 12 is contracted, the hook 14 is brought into contact with the stopper 19, and the hook 14 is rotated to open the concave portion 13a of the engaging body 13. The push plate 7 is positioned at the extrusion port 2 of the compactor 1 with the cylinder 10, and the empty container 3 with the lid 9 fixed thereon is placed.
, the lid body insertion port 4 and the push-in port 2 of the compactor 1
close together so that they match. At this time, the locking rod 26 of the closing rod 25 attached to the lid body 9 is fitted into the open concave portion 13a of the engaging body 13. When cylinder 12 is extended, hook 1
4 is separated from the stopper 19, and the locking rod 26 is gripped by the recessed portion 13a of the engaging body 13 and the hook 14. At the same time, the locking rod 26 integrated with the engaging body 13
is moved together with the closing rod 25 in the extending direction of the cylinder 12, the tip 25a of the closing rod 25 retreats from the hole 28, and the lid 9 is removed from the container 3. When the lid 9 is integrated with the pushing plate 7 in this way, the garbage 6 is pushed into the container 3 by the reciprocating movement of the lid 9. When the filling of the garbage 6 is completed, the lid body 9 is positioned in the garbage insertion port 4 together with the pushing plate 7. Immediately, the cylinder 12 is contracted, and the closing rod 25 moves accordingly, and its tip 25a is fitted into the hole 28. At the same time, the hook 14 is rotated by the stopper 19, and the grip on the locking rod 26 is released.

〔Effect of the invention〕

According to the present invention, the pushing plate inside the compactor is reciprocated together with the lid body, and the lid body can be attached to and removed from the pushing plate and the garbage insertion opening of the compactor using a cylinder attached to the front surface of the pushing plate. Therefore, when the container is fixed to the garbage insertion port, the garbage will not leak out from the container, and the lid will be pushed in and the lid will be attached to and removed from the push-in plate and the garbage insertion port through a series of automatic operations without any manual intervention. becomes possible. In addition, the construction is simplified, especially since the actuation of the hook and the closing rod can be performed using only one cylinder. Furthermore, even if dirt gets caught,
The cylinder reliably engages the closing rod with the hole on the container side to close the garbage insertion port, and the engagement between the locking rod and the hook is ensured by cooperation with the engaging body, and the lid body and Integration with the pushing plate can be strengthened, and the operation of pushing the garbage can be maintained smoothly.

〔Example〕

Hereinafter, the present invention will be explained in detail based on examples thereof. FIG. 1 shows that the extrusion port 2 of a compactor 1 installed in a garbage collection site is in close communication with the garbage insertion port 4 of a container 3 for transporting garbage, and the garbage 6 inputted from the hopper 5 is transferred to the inside of the compactor 1. Push plate 7
8 is an overall cross-sectional view of the garbage pushing device showing a state in which it is pushed in the direction of arrow 8. FIG.

On the front surface 7a of the pushing plate 7, a removable lid 9 is attached to the garbage insertion opening 4 of the container 3 as shown in FIG. .

A mechanism for attaching and detaching the lid body 9 to the push plate 7 and the garbage insertion port 4, respectively, is provided when the push plate 7 and the lid body 9 are located at the garbage insertion port 4 of the container 3.
The description will be made based on FIG. 3, which is a horizontal sectional view of one of the left and right sides. The front surface 7a of the pushing plate 7 that reciprocates inside the main body 1a of the compactor 1 with a cylinder 10 is provided with a cylinder 12 that expands and contracts in the direction of the arrow 11 (the left-right direction of the pushing plate 7). An engaging body 13 with a portion 13a opened toward the lid 9 is attached, and a hook 14 that closes the opening of the concave portion 13a with a tip 14a is rotatably attached to the engaging body 13 with a pin 15. attached. This hook 14
At the base 14b and the end of the cylinder rod 12a,
A spring 16 is tensioned, and the base 14
b is constantly biased in the direction of arrow 17.

In addition, due to the expansion and contraction of the cylinder rod 12a,
Stoppers 19 and 20 are provided that abut the base 14b of the hook 14 and rotate the hook 14 in the left-right direction about the pin 15 as a fulcrum. Therefore, when the hook 14 comes into contact with the stopper 19 and rotates when the engaging body 13 moves, it is possible to release the locking rod 26, which will be described later, by the engaging body 13 and the hook 14. Incidentally, the stopper 20 may be omitted, and the same function can be achieved using only the spring 16.
Note that if a roller 21 as shown in the figure is pivotally supported on the base 14b of the hook 14, the rotation of the hook 14 when the hook 14 comes into contact with the stoppers 19, 20 due to the rotation of the roller 21 is controlled by the roller 21. The sliding contact operation can be made much smoother than when there is no sliding contact.

On the other hand, a pair of upper and lower closing rods 25, 25 supported by a support member 24 so as to be movable left and right in the direction of arrow 23 is provided on the front surface 9b of the lid 9 fitted into the garbage insertion port 4 of the container 3. A locking rod 26, which fits into the recess 13a of the engaging body 13, is fixed between the upper and lower closing rods 25, as shown in FIG. 2, and extends in the vertical direction. Further, holes 27 and 28 are formed in the side of the lid body 9 and the side of the garbage insertion port 4, respectively, into which the respective tips 25a of the closing rods 25, 25 enter. In addition, a fin 29 is protruded from a part of the closing rod 25, and the support member 24
A compression spring 30 is interposed between the two and always urges the closing rod 25 toward the hole 28. In this embodiment, the garbage insertion port 4 is provided in the single-opening discharge door 31 (see Fig. 2) that discharges the garbage from the container 3 after transportation.
It goes without saying that the garbage insertion port 4 may be provided on another side of the container.

The operation of this device will be explained below. First, the fourth
Cylinder rod 1 of cylinder 12 as shown in the figure.
2a is reduced, the roller 21 at the base 14b of the hook 14 is brought into contact with the stopper 19, and the spring 16 is
The hook 14 is rotated about the pin 15 against this, and the recessed portion 13a of the engaging body 13 is opened.

Next, the pushing plate 7 is positioned at the extrusion port 2 of the compactor 1 with the cylinder 10, and in this state, the lid body 9
The attached empty container 3 is brought into close contact with the lid body insertion opening 4 of the container 3 so that the insertion opening 2 of the compactor 1 coincides with the insertion opening 2 of the compactor 1. At this time, the locking rod 26 of the closing rod 25 attached to the lid body 9 is fitted into the open concave portion 13a of the engaging body 13. Note that the container 3 and the compactor 1 are integrally fixed together by a lashing device (not shown) provided on the outside thereof.
The container 3 is prevented from retreating when the garbage 6 is pushed in.

As described above, when the compactor 1 comes into close contact with the container 3 and the cylinder 10 is stopped by a limit switch (not shown), the cylinder rod 12a of the cylinder 12 is extended as shown by the solid line in FIG. At this time, the base 14b of the hook 14 is separated from the stopper 19, and the spring 16 causes the hook 14 to rotate around the pin 15. Therefore, when the locking rod 26 is gripped so as to be surrounded by the concave portion 13a of the engaging body 13 and the tip portion 14a of the hook 14, and the cylinder 12 is fully extended,
The base portion 14b of the hook 14 contacts the stopper 20, and rotation of the hook 14 is reliably prevented. At the same time, the locking rod 26, which is integral with the engaging body 13, is moved together with the closing rod 25 in the direction of extension of the cylinder rod 12a against the compression spring 30. As a result, the tip 25a of the closing rod 25 retreats from the hole 28 to the hole 27, and the lid 9 is removed from the container 3.

When the lid 9 is attached to the push-in plate 7 in this way, the thrown-in garbage 6 is
The back surface 9a of the lid 9 is also pushed into the container 3. When the filling of the garbage 6 is completed, the cylinder 10
The lid 9 moves together with the push plate 7 until it is stopped by the limit switch, and the lid 9 is positioned in the garbage insertion port 4. Immediately, the cylinder rod 12a is contracted, and the closing rod 25 moves accordingly, so that its tip 25a is fitted into the hole 28 rather than the hole 27. At this time, even if there is dust attached to the holes 27 and 28, the strong shrinking force of the cylinder 12 will ensure that the closing rod 25 is firmly attached to the hole 28 on the container side.
The garbage insertion port 4 can be closed by engaging with it. At the same time, the hook 14 is rotated by the stopper 19 and the grip on the locking rod 26 is released.

When the pushing plate 7 retreats in this state, the garbage 6 will not remain in the compactor 1, and the filled garbage 6 will not leak out from the container 3.
Finally, if the lashing device is unfixed, it can be moved for transportation or replaced with another empty container 3. Since the container 3 and the lid 9 are integrally connected by the closing rod 25 which is also biased by a compression spring 30, the lid 9 will not open during transportation of the container 3. In addition, in order to prevent swinging that occurs when the above-mentioned engaging body 13 is moved, it is preferable to provide a guide member (not shown) or the like as appropriate.

As can be seen from the above explanation, the pushing plate inside the compactor is reciprocated together with the lid, and the lid can be attached to and removed from the pushing plate and the dust insertion opening of the compactor using a cylinder attached to the front of the pushing plate. As a result, a series of operations can be performed automatically without causing the garbage to leak from the container when it is fixed to the garbage insertion port, and without manual intervention. In addition, in particular the actuation of the hook and the locking rod can be carried out by only one cylinder, which simplifies the construction and makes its control extremely easy. Further, even if dirt gets caught in a hole provided on the side of the garbage insertion port, the cylinder reliably engages the closing rod with the hole to close the garbage insertion port. In addition, the engagement between the locking rod and the hook is ensured through cooperation with the engaging body, and the integration between the lid body and the pushing plate is strengthened, and the operation of pushing the garbage is always smooth. .
