In this device, the lid 5 is opened, the empty can a is sent into the casing 1, the lid 5 is closed, and then the piston 3 is moved along the chain line to compress the empty can a and open the lid 5 again. Then, the same operation is performed thereafter, and when the required amount of the compressed can a ′ remains in the casing 1, the gate 6 is opened by the cylinder 7 and the piston 3 is moved for a longer time to remove the compressed can a ′. Discharge.

However, this device is poor in workability because the compression action is performed by the reciprocating movement of the piston 3 and the discharge is intermittent. Further, since the casing 1 and the cylinder 2 are connected in series, if an attempt is made to obtain sufficient capacity, the length will be close to 5 m, which will be large and expensive, and will require a large installation space.

By the way, various crushers (crushers)
Inside the casing having an input port for the material to be crushed and an outlet for the crushed object, three horizontal first, second, and third crushing (grinding) shafts are vertically arranged from the input port to the outlet. There is a staggered arrangement in sequence. For example, the crusher is Japanese Utility Model Publication No. 61-15963, and the crusher is Japanese Utility Model 2-15.
No. 557, etc., respectively.

[0006] In these crushers (crushers), when an object to be treated is fed into the casing through an input port, crushing (crushing) is continuously performed by each shaft and discharged. For this reason,
It has good work efficiency, can be made small, and is relatively inexpensive.

Under the above circumstances, the present invention focuses on the crusher and the like, and based on the technology thereof, provides a device for reducing the volume of an empty can, which can continuously perform a compressing and discharging action, and can be inexpensive and downsized. The challenge is to provide.

[0008]

In order to solve the above-mentioned problems, according to the present invention, in a casing having an empty can input port in the upper part and a discharge port in the lower part, from the input port to the discharge port, 3 A volume reducing device having the same construction as that of the above-mentioned crusher in which horizontal first, second, and third compression shafts of a book are provided in a zigzag pattern in the vertical direction in order. A plurality of protrusions are provided on the entire outer peripheral surface of the shaft, at least one of the protrusions is formed into a spike shape, and the first and second compression shafts and the second and third compression shafts are respectively arranged so that the outer peripheral surfaces do not interfere with each other. It was constructed in close proximity.

The gap between the compression shafts may be variable,
In addition, each compression shaft may be supported by an elastic machine that expands and contracts in a direction away from the compression shafts that are close to each other.

[0010]

In the empty can volume reducing device according to the present invention having the above-described structure, the empty cans are loaded into the casing through the loading port while rotating the compression shafts downward and varying the speeds thereof. .

Then, the empty can first has the first
While reaching the space between the compression shaft and the second compression shaft, the spike-shaped protrusions punch holes to remove the residue in the can, while the protrusions on both shafts strip off the empty can. Compressed. The compressed empty can reaches between the second and third compression shafts, is further compressed, is reduced in volume, and is discharged from the discharge port.

At this time, if the compression shaft is supported by an ammunition, when a large incompressible foreign substance is caught between the shafts, one shaft escapes to widen the gap, and the foreign substance is discharged. It is sent to the exit. If the distance between the compression shafts is variable, the degree of compression can be adjusted according to the type of the empty can, and the optimum work can be performed for the empty can.
