The sprocket 53 is suspended symmetrically around at least four sprockets 53 which are symmetrically supported by the shaft 52 so as to run endlessly.

Then, a pair of slat conveyors 51, 51 ′, which are installed between the left and right side plates 52, 52, are arranged vertically, and the crushed thickness of the empty can A is provided between the tips of the upper and lower conveyors 51, 51 ′. Both conveyors 51, 51 'are made to face each other in a V shape with a corresponding gap 55, and the side plates 52, 52 of both conveyors are supported by the fixing member 56 by the shaft 53a of the sprocket 53, and at the same time, the lower conveyor 51' The tip of the side plate 52 was supported on the fixed support member 57, the tip of the side plate 52 of the upper conveyor 51 was in a free state, and the elastic spring 58 was applied to the free end from above.

In FIG. 6, reference numeral 60 denotes a drive-running motor for the upper and lower conveyors 51 and 51 ′, which drives the sprockets through interlocking mechanisms 61 and 62, respectively, so that the upper and lower conveyors 51 and 51 ′ face each other in a V shape. The surfaces were made to run together toward the tip, and the empty can A supplied to the V-shaped gap was transferred to the crushing gap 55.

[Problems to be solved by the device]

 By the way, in the conveyor type empty can press machine as described above, since many strip-shaped steel plates are used for the upper and lower conveyors, the strip-shaped steel plates are easily damaged and wear quickly, and the upper and lower conveyors crush and crush the empty cans. However, since they are conveyed by pinching, a large amount of power is required to drive the conveyor.Therefore, separate driving motors are provided for the upper and lower conveyors, and since a large amount of power is required, a single-phase power supply cannot be used. A three-phase power source had to be used, and there were restrictions on the power source. Further, in the case of the hydraulic empty can press machine, various hydraulic devices such as a hydraulic pump are required, which causes a problem of high cost.

Therefore, the present invention provides an empty can pressing machine which is an inexpensive mechanical type and which is configured so that it can be used even with a single-phase power source by using a single drive motor, thereby solving the above-mentioned problems. The purpose is to do.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned circumstances, and a pair of press plates are opposed to each other in a substantially V shape with an interval at one end corresponding to the crushed thickness of the treated empty can, and diagonally downward. And a plurality of bearings are fixed to the rear surfaces of the substantially V-shaped facing surfaces of the pair of press plates at regular intervals, and both ends are rotatably supported by the machine body. Through the large diameter part of the eccentric shaft, the driving force of a single drive motor is transmitted to each eccentric shaft via the power transmission mechanism, and each eccentric shaft is rotated in the same phase, and a pair of presses are pressed. The plates swing toward the opposite surfaces and toward the lower end, and the treated empty cans supplied to the pair of press plates are continuously crushed and discharged from the lower end, which is the tip of the V-shaped gap. It is characterized by

[0008]
