Abstract

PURPOSE:To sort compressed empty cans to magnetic and non-magnetic materials by providing a permanent magnet and a specific knock-out bar to a press plate for crushing tin plates, Al juice cans, etc. which are charged into the machine and are supported horizontally. CONSTITUTION:An empty can 2 charged into a hopper 1 is dropped onto a vertically movable support metal 3 by a magnet solenoid 5. A hydraulic cylinder 6 upon sensing the drop advances a press plate 7. The can 2 is crushed between a receiving plate 12 and the plate 7 and when it is thoroughly crushed, the plate 7 is retreated. If the can 2 is a non-magnetic material can, the can is pushed out by the plate 12 held pressed by a spring 14 and falls onto a discharging chute 15, from which it is stored in a containing box 16. On the other hand, the magnetic can is attracted to a permanent magnet 11 on the front face of the plate 7 and is returned together with the plate 7, but at this time the rear end of a knock-out bar 8 contacts with a frame 10 and therefore the bar 8 projects from the plate 7 against the force of a spring 9, thereby knocking the can off from the magnet and dropping the same onto a discharging chute 17. The dropped can is stored in a containing box 18.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention randomly puts empty cans such as tin and aluminum juice cans into a predetermined hopper, compresses them, and then sorts them into the material side of the can to create empty cans that can be stored. This invention relates to a can compression device.

Empty can pollution has recently become a major problem. Collect these empty cans and crush them one by one or many at once using a compressor.
It is known that things are stored in storage baskets. However, in this case, the empty cans that are thrown in are not concerned with the materials that make up the cans.
Since they are compressed one after another, it requires a great deal of effort and expense to sort them out at the stage of reuse, which is undesirable.

The present invention improves the conventionally known compressor as described above, and uses a machine that puts arbitrarily placed empty cans into the hopper of the compressor and compresses them with a hydraulic cylinder. Among the empty cans, those made of tin are attracted with a magnet and then allowed to fall by gravity, while those made of aluminum are immediately separated and dropped so that they can be automatically sorted, as shown in the drawing below. Explain with reference to.

In the figure, reference numeral 1 denotes a hopper for charging empty cans 2, into which empty cans 2 are randomly loaded from above.

5 is a can holding fitting for the crushing part 4, and a magnet solenoid 5
It is movable in the vertical direction. 5a C is a spring that elastically supports the support fitting 4.

The crushed portion 4 will be explained. Reference numeral 6 denotes a hydraulic cylinder, and a push plate 7 is attached to the tip of the hydraulic cylinder so as to be movable in the horizontal direction. The push plate 7 is provided with a plurality of holes, into which a protruding rod 8 for pushing out a compressed magnetic can is loosely fitted.

The protruding rod 8 is urged in the retracting direction by a spring 9. Reference numeral 10 denotes a fixed frame, and when the rear end of the protruding rod 8 comes into contact with this frame, the protruding rod 8 protrudes from the push plate 7 against the spring 9. 11 is a permanent magnet embedded in the center of the front surface of the push plate 7.

A receiving plate 12 is provided opposite the push plate 7, and a plurality of guide bolts 13 are fixed to the receiving plate, and the guide bolts pass through the frame 10. 14 is the frame 10 and the receiving plate 12
A spring is installed in between.

15 is a discharge chute for the compressed non-magnetic mortar, and 16 is also a storage box. 17 is a discharge chute for compressed magnetic cans, and 18 is also a storage box. 19 is a hydraulic unit;
20 is a receiving roller of the storage box 16.18.

A sensing device (not shown) operates the hydraulic cylinder 6 to move the push plate 7 forward. The empty can 2 is crushed between the receiving plate 12 and the pushing plate 7.

When it is completely collapsed, a retreat command is transmitted to the hydraulic cylinder B,
The push plate 7 is moved back. At this time, if the empty can 2 is a non-magnetic can (for example, an At can), it is pushed out by the receiving plate 12 pressed by the spring 14, falls onto the discharge chute 15, and accumulates in the storage box 16.

On the other hand, magnetic cans such as tin cans have a permanent magnet 11 on the front of the push plate 7.
It is attracted to and returns together with the push plate 7. However, when the rear end of the protruding rod 8 hits the frame 1o, the protruding rod 8 protrudes from the push plate 7, is pushed away from the permanent magnet 11, falls onto the discharge chute 17 under its own weight, and is stored in the storage box 18.

With the above configuration, empty cans 2 are randomly placed in the hopper 1.
The compressed empty cans are sorted into magnetic and non-magnetic ones and stored, which is convenient for later resource recycling.

Further, most of the structure is composed of mechanical parts, and the mechanism is simple, which is advantageous in terms of cost and maintenance.

Furthermore, since the empty cans can be arbitrarily thrown into the upper chute, even children can easily operate this device if it is placed in an amusement park, making it suitable as an environment beautification device.
