BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pusher plate positioning device for positioning a pusher plate in a compactor container in which dust or the like is packed in the container from a compactor.

[0002]

2. Description of the Related Art Generally, there is a compactor container as a device for compressing and packing a container from dust and a compactor.

This compactor container is disclosed in Japanese Patent Publication Sho 55
As disclosed in Japanese Patent Application Laid-Open No. 29796, while a pushing plate is slidably fitted in a compactor body, a container is connected to the compactor, and a lid of a pushing port of the container is attached to the pushing plate. The pushing plate is slid back and forth to compress the dust in the compactor body and pack it in the container.

When the container is separated from the compactor, the lid attached to the pushing plate is attached again to the pushing port of the container. At that time, the stop position of the pushing plate is controlled by the deviation between the detection position of the position detection device and the set position.

[0005]

However, in the above-mentioned compactor container, the stop position of the pushing plate is controlled by the position detecting device, so that there is a problem that the stop control is unreliable. .

That is, it is necessary to push the pushing plate once into the container and then to return it to the stop position. The electrical control is inaccurate and the lid cannot be smoothly attached and detached. there were. In particular, since the dust is compressed and pushed in, there is a problem that the impact is large, the stop position of the pushing plate is likely to change, and the reliability is poor.

The present invention has been made in view of the above problems, and an object thereof is to improve the accuracy of the stop position of the pushing plate.

[0008]

In order to achieve the above-mentioned object, the means taken by the present invention is to provide a retractable positioning stopper in the compactor body.

Specifically, the means taken by the device according to claim 1 is as follows. First, a compactor in which a pushing plate is slidably fitted and inserted in a compactor body having an extrusion opening on the front surface, and a compactor on the rear surface. A compactor container provided with a container which is opened, is connected to the front surface of the compactor by aligning the pushing port and the pushing port, and the lid of the pushing port is detachably attached to the pushing plate. Is intended for. The compactor is provided with a positioning stopper that stops the pushing plate at the connection position between the pushing plate and the lid so that the positioning stopper can be retracted in the compactor body.

[0010]

With the above construction, in the device according to claim 1,
The push-out port of the compactor is connected to the push-in port of the container, the lid of the container is attached to the push-in plate of the compactor, and the push-in plate is reciprocally slid in the compactor body. Due to the reciprocal sliding of the pushing plate, dust and the like in the compactor body are compressed and packed in the container. At the time of this packing, the positioning stopper retracts to the outside of the compactor body and does not interfere with the pushing plate.

When the inside of the container becomes full,
The lid attached to the pushing plate is replaced with the container from the pushing plate, and the pushing port of the container is closed. At this time, the pushing plate is moved forward to push the front part of the pushing plate once into the container, and then the pushing plate is moved backward to position the lid at the pushing port. When the pushing plate moves forward, the positioning stopper is projected into the compactor, and then,
When the pushing plate is retracted, the pushing plate comes into contact with the positioning stopper, and the lid body is accurately positioned at the pushing port and stopped.

[0012]

Therefore, according to the invention of claim 1,
Since the compactor body is provided with the pushing plate positioning stopper, the pushing plate can be accurately positioned at the mounting position of the lid of the container, so that the work of attaching and removing the lid can be smoothly performed.

In particular, since the pushing plate is stopped by contact with the positioning stopper, the pushing plate can be stopped more accurately and surely as compared with the case where it is controlled by a limit switch or the like, so that it should be highly reliable. You can

Further, since the pushing plate can be accurately stopped even if the impact of the compactor is applied, it is possible to maintain a high stopping accuracy for a long period of time with little change over time.
