Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a container lid plate attachment/detachment device for a compactor/container, for attaching/detaching a lid plate that also serves as a pushing plate for opening/closing an entrance/exit of a container to/from a pushing member of a compactor (waste pushing machine). It is related to.

The outlet of the container is connected to the outlet of the compactor, and the pushing member of the compactor enters the container through the outlet of the container, compressing and pushing the waste such as garbage thrown into the compactor into the container. Compactor containers are conventionally known, and in such compactor containers, a lid plate that closes the entrance and exit of the container is separated from the entrance and connected to the pushing surface of the pushing member of the compactor, and the above-mentioned compression pushing operation is performed. I try to do this.

Therefore, the lid plate that also serves as a push plate is detachably connected to the container's entrance/exit. Conventionally, the lid plate that also serves as a push plate and the container's entrance/exit have to be attached/detached because there is a long gap between the container and the lid plate. This is done by inserting and removing the bar-tacking rod, and the connection of the lid plate to the front of the pushing member of the compactor is performed separately using another connecting mechanism, and the lid plate is attached to and removed from the container entrance and exit. Connecting the pushing member to the pushing surface is cumbersome and inefficient.

Therefore, the present invention enables the lid plate, which also serves as a push plate, to be detached from the container, automatically connected to the push member of the compactor, and detached from the push member, without using a long bar-tacking bar as in the conventional one. A simple and compact compactor that can be automatically connected to the container entrance/exit.
The object of the present invention is to provide a container lid plate attachment/detachment device for a container.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A is a compactor, B is a container, and they are connected together by a conventionally known lashing mechanism (not shown), and are used to dispose of garbage etc. thrown into the compactor A. It is possible to push objects into container B.

Next, to explain the structure of the compactor A, a box-shaped compactor main body 1 installed on an installation surface has an extrusion port 2 in the front and an input port 3 in the front part of the upper wall thereof. A hopper 4 integral with the compactor body 1 is disposed above the mouth 3.

A pushing member 5 is housed inside the compactor body 1 so as to be slidable back and forth, and between the pushing member 5 and the compactor body 1,
A pushing cylinder 7 is connected, and the pushing member 5 is slid back and forth by the expansion and contraction operation of the pushing cylinder 7, and compressible waste such as garbage thrown in from the hopper 4 can be pushed out from the extrusion port 2.

A pushing surface 6 is formed on the front surface of the pushing member 5, and a rectangular mounting frame 8 is protruded from the center of the pushing surface 6. A pair of telescopic cylinders 9 are mounted symmetrically on this mounting frame 8. A retaining piece 11 is provided at the tip of the piston rod 10 of the telescopic cylinder 9, and the engaging piece 1
1 can be engaged with a connecting piece 27 of a lock pin 25, which will be described later.

At the top and bottom of the pair of telescopic cylinders 9, upper and lower contact plates 12.13 are stretched on the front surface of the mounting frame 8, and these upper and lower contact plates 12.13 serve as lid plates for container B, which will be described later. Further, restraining pieces 14 projecting laterally are fixed to both sides of the mounting frame 8, and a connecting piece 27 of a lock pin 25, which will be described later, is attached to these restraining pieces 14. can be engaged.

A receiving surface 15 for supporting the edge frame 23 of the lid plate 21 of the container B is formed on the upper surface of the top plate 12.

The restraining piece 14, the receiving surface 15, the edge frame 23, and the connecting piece 27 constitute the connecting device C of the present invention.

Next, to explain the structure of the container B, there is a gate 1 on the open end surface of the container body 16 formed in a box shape.
7 is pivoted so that it can be opened and closed.

An entrance/exit 18 is opened in the center of the gate 17, and a rectangular frame 19 surrounding this entrance/exit 18 has insertion holes 20 formed in opposing inner surfaces thereof.

The entrance/exit 18 of the container B is opened and closed by a lid plate 21 fitted therein.
1, on its outer surface side, three sides of a rectangular plate 22 excluding the lower side are bordered by an edge frame 23, and on both sides of the edge frame 23, insertion holes that correspond to the insertion holes 20 are formed above and below. Holes 24 are formed, lock pins 25 are inserted into each of these insertion holes 24, and these lock pins 25 are connected by a connecting piece 27, and this connecting piece 2
7 is a spring 28 whose one end is fixed to the edge frame 23 of the cover plate 21.
The spring 28 is connected to the lock pin 25.
It is biased so that it protrudes outward.

Next, the operation of one embodiment of the present invention will be explained.
As shown in the figure, when the container B is separated from the compactor A, the entrance/exit 18 formed in the gate 17 of the container B is closed by the cover plate 21.

In this case, the lock pin 25 provided on the lid plate 21 projects outward from the side end of the lid plate 21 and is inserted into the insertion hole 20 of the container B due to the elastic force of the spring 28, and the lid plate 21 is placed in the closed position. Locked.

Now, container B is moved, its gate 17 is joined to the front of compactor A, and the two are connected together by a conventionally known lashing mechanism (not shown) as shown in FIG. 2, which is also clearly shown in FIG. The upper and lower contact plates 12 of the pushing surface 6
, 13 are brought into contact with the front surface of the cover plate 21, and at the same time the cover plate 21
The upper side of the edge frame 23 projecting outward is engaged with and supported by the receiving surface 15 on the upper surface of the mounting frame 8 of the pushing surface 6, and the engaging piece 11 at the tip of the pair of telescopic cylinders 9 is connected to the connecting piece of the lock pin 25. 2
7 and face each other.

Next, when the pair of telescopic cylinders 9 are both contracted, the engaging piece 11 at the tip of their piston rods engages the connecting piece 27 and draws the lock pin 25 inward against the spring force of the spring 28. The lock pin 25 can separate the lid plate 21 from the entrance/exit 18 of the container B by recessing inward from the side end of the lid plate 21 through the insertion hole 20.

At this time, as shown in FIG.
1, when an external force in a direction away from the pushing surface 6 is applied, the connecting piece 27 engages with the restraining piece 14 and the separation of the cover plate 21 is restrained.

The lid plate 21 separated from the entrance/exit 18 of the container B as described above is automatically connected to the pushing surface 6 of the pushing member 5.

When the pushing cylinder 7 is expanded and contracted in this state, the pushing member 5 slides back and forth with the cover plate 21 connected to the pushing surface 6, and the garbage etc. thrown into the compactor body 1 from the hopper 4 is disposed of. Objects can be pushed into the container body 16.

When the pushing of the waste into the container B is completed, the pushing member 5 is moved until the cover plate 21 matches the entrance/exit 18 of the gate 17, and then the pair of telescoping cylinders 9 is extended, and the spring 28 is activated. The force causes the lock pin 25 to protrude outward and fit into the insertion hole 20 of the container B, and the cover plate 21 is separated from the pushing surface 6 of the pushing member 5, and at the same time is bar-tacked to the entrance/exit 18 of the gate 17. The entrance/exit 18 can be closed.

As described above, according to the present invention, there is a compactor A in which the pushing member 5 is slidably provided in the compactor main body 1 which has the extrusion port 2 opened in the front surface thereof, and the inlet/outlet port 18 that can be connected to the extrusion rotor 2. is opened at one end surface, and its entrance/exit 18
a container B in which a lid plate 21 is fitted;
are each formed into a rectangular shape, and insertion holes 20 are opened on the opposing inner surfaces of the entrance/exit port 18, and the lid plate 2
The outer surface of the cover plate 21 is provided with a lock pin 25 that protrudes outward from the side edge of the cover plate 21 and can be inserted into and removed from the insertion hole 20, and a spring 28 that biases the lock pin 25 in the insertion direction. On the other hand, the lock pin 25 is provided on the front surface of the pushing member 5 against the urging force of the urging device.
A driving device such as a telescopic cylinder 9 that can be operated in the extraction direction is provided, and the two surfaces are joined between the outer surface of the lid plate 21 and the front surface of the pushing member 5, and the lock pin 25 is moved in the extraction direction. Since a connecting device C is provided that connects the cover plate 21 and the pusher member 5 together when activated, the lock pin 25 can be inserted while the pusher member 5 is advanced and its front surface is joined to the outer surface of the cover plate 21. If it operates in the extraction direction, the cover plate 2
1 can be automatically separated from the container entrance/exit 18 and connected to the pushing member 5, the lid plate 21 can be effectively used as a pushing plate, and the lock pin 25 can be inserted in the insertion direction from the connected state. When the lid plate 21 is operated, the lid plate 21 can be automatically separated from the pushing member 5 and connected to the container entrance 18. Therefore, unlike the conventional method, when the lid plate 21 is attached to and removed from the container entrance 18, There is no need to manually insert and remove long bartacking rods, reducing labor and significantly increasing work efficiency.

In particular, in the present invention, all the mechanisms for attaching and detaching the lid plate 21 to the container entrance/exit 18 and the front surface of the pusher member 5 can be housed between the front face of the pusher member 5 and the lid plate 21, making it extremely compact. Therefore, there is no need to provide the attachment/detachment mechanism on the inner surface of the compactor body 1 or inside the container entrance/exit 18.
The structure of the inside and the side part of the pushing member 5 can be simplified,
Coupled with the fact that the cover plate 21 and the entrance/exit 18 have a simple rectangular shape, each component can be easily manufactured and processed, which can contribute to cost reduction.

Furthermore, when the cover plate 21 is separated from the front surface of the push-in member 5, all of the attachment/detachment mechanism can be opened to the outside, so maintenance and inspection of the mechanism is easy.

Moreover, since the attachment/detachment mechanism is disposed on the outer surface side of the lid plate 21, that is, on the opposite side to the pushing surface, there is a risk that the waste that is pressed and compressed by the lid plate 21 toward the container B may enter and adhere to these mechanisms. Therefore, the attachment/detachment mechanism can be operated smoothly and reliably at all times, and there is no risk of the waste material leaking outside through the attachment/detachment mechanism.
