CONSTITUTION:A stopper 21 on an upstream side ascends by detecting the passage of the large-sized metallic vessel and stops the succeeding large-sized metallic vessels when the large-sized metallic vessel passes the stopper 21 on the upstream side in the state that the stopper 21 on the upstream side is down and a stopper 22 on the downstream side is up. Next, an air cylinder 51 on the roller conveyor side operates to push the large-sized metallic vessel into a housing 31. On the other hand, an air cylinder 53 on a housing side operates as well to clamp the large-sized metallic vessel under a pressing plate 42, thereby positioning the large-sized metallic vessel. Next, a hydraulic cylinder 41 operates and the large-sized metallic vessel is crushed by the pressing plate 42. Finally, an air cylinder 53 on a housing side operates to push out the crushed matter onto the roller conveyor 11. The crushed matter is transported downstream by the roller conveyor 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing device for large metal containers. For example, in the field of food processing, agricultural products that are harvested in large quantities over time are processed locally and stored in large metal containers, typically 100-300 liter drums, for storage. Accordingly, these are appropriately transported to the secondary processing site, and the primary processed product is emptied from the large-sized metal container for secondary processing. Large metal containers after the primary processed product has been emptied may be sent for reuse, but are often discarded. In preparation for disposal, if you store the large metal container after emptying the primary processed product as it is and transport it to the processing plant, a huge space is required for storage and transportation. It is required to crush and reduce its volume. The present invention relates to a crushing device for a large metal container as described above, which meets such a demand.

[0002]

2. Description of the Related Art Heretofore, as a device for crushing a metal container at a place where contents are emptied, various devices for small metal containers have been proposed and used (Japanese Patent Laid-Open No. Hei 5 (1993) -58).
305498). In all of these, a large number of small metal containers placed in the housing are pressed at once by a motor-driven or cylinder-driven pressure plate to be crushed. On the other hand, when treating large-scale wastes such as automobile bodies that are to be disposed of in a specialized treatment plant, the large-scale wastes thrown into a robust housing are pressed by a pressure plate driven by a powerful hydraulic cylinder. It is also being crushed. However, there has not been proposed a device for crushing the large metal container as described above at the place where the contents are emptied. In a factory where the contents are emptied from a large metal container and then subjected to secondary processing, the fact is that it is difficult to handle the large metal container after the contents are emptied.

[0003]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to store a large metal container after emptying the contents in a factory where the contents are emptied from the large metal container for secondary processing. It takes a huge amount of space to transport it to processing plants and processing plants, and it is difficult to handle it.

[0004]

SUMMARY OF THE INVENTION The present invention, however, is directed to a conveyor for carrying a large metal container, and an upstream stopper and a downstream stopper for stopping one large metal container on the conveyor. And a housing installed facing the conveyor between both stoppers from the horizontal direction,
A hydraulic cylinder mounted on the upper part of the housing and having a pressure plate attached to the lower end of its cylinder rod, and a large metal container that has been stopped are pushed into the housing from above the conveyor and positioned directly below the pressure plate. And a set of advancing / retreating means for pushing out the crushed material of the large metal container from the inside of the housing onto the conveyor.

In the present invention, the conveyor for carrying a large metal container is not particularly limited as long as it can carry a large metal container, such as a flat conveyor, a roller conveyor, a vibrating conveyor, and the like. A roller conveyor that can be stably transported and is easily slid on the conveyor and pushed into the housing described later from the conveyor is preferable. The conveyor is equipped with an upstream stopper and a downstream stopper for stopping one large metal container between them. Both stoppers detect that a large metal container has been conveyed on the conveyor with a limit switch or a photoelectric tube, etc., and move or retreat by motor drive or cylinder drive according to the detection signal, or move up and down. Known control means can be applied per se. Both stoppers are not particularly limited in shape such as rectangular cross section, triangular cross section, wedge cross section, etc., but those having a length that extends over the width direction of the conveyor are preferable, and when a roller conveyor is used as the conveyor. Is preferably one that moves up and down between the rollers that make up the roller conveyor.

In order to stop one large metal container more reliably between the upstream stopper and the downstream stopper when a plurality of large metal containers are continuously conveyed on the conveyor. Regulates the driving of the conveyor on the upstream side in conjunction with the stopper on the upstream side,
Alternatively, a third stopper interlocking with the upstream stopper is provided further upstream than the upstream stopper, and the third metal stopper regulates a large metal container conveyed to the upstream stopper. Preferably, the third stoppers in this case are provided in pairs on the left and right sides in the width direction of the conveyor, and move forward and backward from the left and right sides of the large metal container conveyed on the conveyor to regulate the conveyance of the large metal container. Those are preferable.

A housing is installed with the conveyor between the upstream stopper and the downstream stopper facing in the horizontal direction. The housing is mainly for safety in the crushing work, and at least the side surface facing the conveyor is open, and the bottom surface thereof is normally located on the same horizontal plane as the conveyor conveyance surface. A hydraulic cylinder is mounted on the upper part of the housing, and a pressure plate is attached to the lower end of the cylinder rod of the hydraulic cylinder, and the pressure plate is usually located inside the housing.

One of the advancing and retracting means is provided on the conveyor side between the upstream stopper and the downstream stopper, and one of the housings is installed on the side of the housing facing the conveyor from the horizontal direction. The other advancing / retreating means is provided opposite to the advancing / retreating means, and one set of these advancing / retreating means pushes one large metal container stopped between both stoppers from above the conveyor into the housing. It is positioned just below the pressure plate, and the crushed material of the large metal container is pushed out from the inside of the housing onto the conveyor. The advancing / retreating means is not particularly limited as long as it can be advanced / retreated by a motor drive or a cylinder drive. It is preferable that a pressing plate is attached to the tip of the cylinder rod, and at least one of the pressing plates is a guide plate. In this case, the guide plate has an inner peripheral surface that is shaped to conform to the outer peripheral side surface of the large-sized metal container, or an inner peripheral surface of the guide plate and the outer peripheral side surface of the large-sized metal container.
The shape is such that it abuts at three or more points, preferably three or more points.

[0009]

For convenience, the conveyor is a roller conveyor, and an upstream stopper and a downstream stopper are provided between the rollers constituting the roller conveyor, and both stoppers move up and down with respect to the transport surface of the roller conveyor. The operation of the present invention will be described below. First, when one large metal container passes through the stopper on the upstream side while the stopper on the upstream side is descending and the stopper on the downstream side is rising, this is detected by, for example, a limit switch, and By the detection signal, the stopper on the upstream side rises and stops the subsequent large metal container conveyed from the upstream side. There is one large metal container between both stoppers, and this large metal container is stopped by the stopper on the downstream side.

Next, the advancing / retreating means on the roller conveyor side moves forward to push the large metal container stopped between both stoppers into the housing, while the advancing / retreating means on the housing side also moves forward to move both sides. When the large metal container is sandwiched by the advancing and retreating, the positioning means is positioned just below the pressure plate, and then both advancing and retracting means are retracted. Subsequently, the pressure plate descends to crush the large metal container and then rises. The lowering of the pressure plate
It can be stopped by a constant pressure operation of the hydraulic cylinder, or by equipping the housing with, for example, a photoelectric tube, it is stopped by a detection signal from the photoelectric tube that detects that a large metal container has been crushed to a certain height or less. You can also As an example, if a 25 ton hydraulic cylinder is used, a drum with a height of about 1 m can be crushed to a height of about 10 cm.

Finally, the advancing / retreating means on the housing side advances to push the crushed material onto the roller conveyor, and the crushed material pushed out is conveyed further downstream by the roller conveyor. At this stage, the downstream stopper has already descended, and when the crushed material passes through the downstream stopper, this is detected by, for example, a limit switch, and the detection signal causes the downstream stopper to move upward, Stopper moves down. The following is a repeat of this.
