As disclosed in Japanese Unexamined Patent Publication (Kokai), an empty can guided from an inclined rolling surface, a pressing plate pivotally supported at a lower end and linked to an electric motor, and a receiver fixed to a side wall of a machine frame. The empty can is crushed by moving the pressing plate forward by the operation of the electric motor, and the crushed can whose load is released when the pressing plate returns is dropped to the separating means for non-magnetic and magnetic cans. There is a prior art that is made to do so.

[0003]

By the way, as in the above-mentioned prior art, in the structure in which the pressing plate whose lower end is axially supported is moved toward and away from the receiving plate fixed to the side wall of the machine frame, the pressing plate serves as the receiving plate. In contrast, it approaches and separates in an inclined shape. In this way, in the method of crushing an empty can with the inclined pressing plate that rotates in an inclined manner with respect to the receiving plate, a force for removing the empty can to the outside (specifically, upward direction) is generated at the time of crushing. The plate must be made sufficiently long to ensure the crushing, and the inclined rolling surface is provided separately at the upper end of the machine frame, which causes the problem that the device itself becomes very large. is there.

The present invention has been made in view of the above-mentioned conventional circumstances, and its object is to provide an empty can compressor in which an empty can is crushed by a movable plate which approaches the receiving plate in an inclined manner. An object of the present invention is to provide a compact empty can compressor that can reliably crush an empty can to a predetermined size by using a short movable plate that also serves as a rolling surface of the can.

[0005]

The technical means taken to achieve the above object are a movable crush plate having a lower end pivotally supported in a downwardly inclined shape, and a first electric motor for rotating the movable crush plate. A first spring means for constantly urging the movable crush plate in the return direction, a fixed receiving part standing upright with a drop space of the crush can left in front of a shaft supporting part of the movable crush plate, and the fixed receiver. A movable crush plate detecting means for outputting to the first electric motor a detection signal for stopping at a predetermined position a movable crush plate that rotates in the forward direction so as to crush the empty can first. A can escape prevention plate provided at the upper end and pushed by the movable crush plate against the biasing force of the second spring means, and the first electric motor is operated again after the first electric motor is stopped and after a desired time has elapsed. Move the movable crush plate to the fixed receiving part, and A timer means for further secondary crushing the can, and gist in that it comprises a non-magnetic cans provided directly under the falling space, and separation means of the magnetic can. Further, the separating means is arranged in a second electric motor in which a magnet attached to a rotating body provided on a motor rotating shaft is located immediately below the drop space, and in a location on the rotation locus of the magnet that does not face the drop space. It is effective if it is composed of a can hook.

The movable crush plate is continued until it is detected by the detection means, and at that time, the escape of the empty can that is about to be removed by receiving the upwardly acting exclusion force is prevented by the can escape prevention plate. When the operation of the first electric motor is stopped by the detection signal of the movable crush plate by the detection means, the movable crush plate receives the urging force of the first spring means, returns to the initial state, that is, the return direction, and operates again. 1) Receives the operation of the electric motor and rotates in the forward direction until it comes close to the fixed receiving portion, and secondarily crushes the empty can. At this time, the primary crushed crushed can is further crushed secondary at the position where it has dropped to the vicinity of the shaft support portion, so crushing is performed reliably. The crushing can that falls from the dropping space when the movable crushing plate that receives the urging force of the first spring means falls is separated into a non-magnetic can and a magnetic can via the separating means. (Claim 2) When the crushed empty can is a magnetic can,
Rotate while attracting with a magnet, scrape off with a can hooking claw, and drop it from a drop space to a place different from the non-magnetic can dropped downward.

[0007]

As described above, the present invention rotates the movable crush plate also serving as the rolling surface of the empty can in the forward direction, and prevents the empty can from escaping to the outside by the can escape prevention plate while performing the primary crush. after, the crushing cans by the return of the movable crushing plate is dropped to the shaft support vicinity, because to the ulcer Suyo crush cans more flat in performing further secondary crushing at that position facing the inlet of the can It is possible to reliably crush to the desired flatness amount by crushing the empty can in stages by using a short movable crushing plate that also serves as the rolling surface of the empty can that directly receives the empty can that is provided in.
