Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a crusher for empty cans.
It is a simple product that can be used for retail stores or home use.

[Conventional technology and issues]

Conventionally, there are various types of crushers for empty cans. A typical method is to crush an empty can by sandwiching it between a pair of large-diameter rollers, but this requires rollers with a relatively large diameter compared to the can diameter, and it also ensures that the empty can is crushed on both sides. Auxiliary means and the like were also required to allow the rollers to fit in between the rollers. There are also large presses that crush a large number of empty cans at once, but these are not suitable for large-scale commercial use and are not suitable for retail stores that only handle small quantities or for home use. Ta.

In order to solve the above problem, the inventor of the present invention has previously devised and applied for an empty can crusher with a small and novel structure (Utility Application No. 1-131564). Since the empty can is crushed into a flat shape, there is a problem in that the flattened empty can has a relatively large planar size.

[Means to solve the problem]

The present invention solves the above-mentioned problems by providing a crusher that adopts a small and novel structure and can reduce the size of the oblique plane of a can after being crushed by applying pressure to the upper and lower ends of the can. It is.

In other words, the empty can crusher according to the present invention is
A drive shaft is provided vertically in the center of the second half of a rectangular support frame having an opening at least at the front end, and a plate-shaped eccentric cam 11 is fixed horizontally to the middle part of this drive shaft, and the upper end of this drive shaft is fixed horizontally. A drive link 12 is provided on the left and right sides of the drive shaft, and a guide shaft 13 is disposed in parallel across the front and back of the support frame, and a pusher 18 with a pusher head 14 at the tip is attached to the guide shaft. The eccentric cam 11 is located on the rear surface of the pusher head so as to be movable back and forth, and the can holder has at least a V-shaped lower half when viewed from the front within the opening of the support frame in front of the pusher head.
20 is provided so that a gap 19 is maintained between its tip and the front plate, and on the other hand, above the can holder, an opening/closing shutter 21 having almost the same shape as the can holder is interlocked with the drive link at the upper end of the drive shaft. It is characterized by being provided so that it can be opened and closed.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 and 2 show a rectangular support frame made of angle material, with a front plate provided at its front end and an opening provided at the rear of the front plate. is a drive shaft installed vertically in the rear half of the support frame with bearings 30, 30, and is connected to a geared motor 31 placed at the bottom via a coupling ring 32, with a drive link 12 at its upper end. It is set horizontally. 11 is an eccentric cam horizontally fixed to the middle part of the drive shaft.

Reference numeral 18 denotes a pusher for empty cans, which is equipped with a home base-like pusher head 14 at the front end, a pusher roller 15 at the rear, and return rollers 16 on the left and right sides of the rear end, and between the pusher roller and the return roller. The eccentric cam 11 is provided so as to be movable back and forth along two parallel guide shafts 13, 13 provided on the left and right sides across the drive shaft.

Reference numeral 20 denotes a can holder, which is provided extending forward from the outer side of the home base-shaped pusher head as shown in the drawing, and is arranged so that a gap 19 exists between its tip and the front plate. There is. The pusher head 14 is moved along the inner surface of the can holder 20 by the rotation of the eccentric cam 11, and the front and rear rollers 15, 16 are moved along the inner surface of the can receiver 20.
It reciprocates back and forth through the.

Reference numeral 21 denotes an opening/closing shutter located above the can holder 20, which has a funnel-like shape from the front as shown in FIG. 3, and is divided at the center so that it can be moved toward and away from the left and right sides. The shutters are opened and closed via opening/closing arms 22 connected to the outside of each shutter, and the rear ends of these opening/closing arms are pivotably supported on the rear upper surface of the support frame as shown in FIGS. 4 and 5. 24, and a pin 25 is provided slightly forward of the pin 25, and the pin is fitted into a long hole 26 of a driven link 23 connected to the drive link 12 provided at the upper end of the drive shaft.

Further, a coil spring 27 is provided immediately after the shutter of this opening/closing arm 22, and normally keeps the shutter in a closed state.

[Effect]

The opening and closing timings of the shutter 21 and the pusher 18 are set in a relationship as shown in FIG. That is, the position shown in Figure 1 is 0° in Figure 8.
The shutter 21 is almost fully closed as shown in FIG. 4, and the pusher 18 is fully open as shown in FIG. At this position, an empty can is put into the funnel-shaped shutter 21, and the motor is driven to rotate the eccentric cam. It opens fully between ° and 20 ° and drops an empty can onto the can receiver 20, and then gradually closes. During this time, the pusher remains fully open, and after the shutter is fully closed, it moves forward, and when it reaches 180 degrees, it fully closes, completely crushing the empty can between it and the front plate. This state is
This lasts for 50°, after which the pusher gradually retreats back to its open position.

The shutter and pusher repeat the above movements due to the 111 rotations of the eccentric cam, so if you manually load empty cans one by one while the shutter is closed, the rotation of the drive shaft will cause the shutter and pusher to move through the arm 22. 5
As shown in the figure, the shutter 21 opens momentarily (within 10 degrees) and drops the empty can onto the can receiver 20, and the empty can is crushed by the forward drive of the pusher by the eccentric cam as shown by the two-dot chain line in Figure 7. The flattened empty can then naturally falls downward from the gap 19 in front of the can receiver. To prevent empty cans from falling, place a bucket or similar at the bottom of the opening.
All you have to do is collect it and carry it out as appropriate.

Although the pusher roller 15 and the return roller 16 of the pusher in the above embodiment are used to smoothly slide against the eccentric cam 11, they are not necessarily provided, and the opening/closing mechanism of the shutter 21 is also similar to the illustrated example. The present invention is not limited to this, and may be operated using an appropriate cam, lever, or the like.

[Effect of idea]

As mentioned above, the present invention has a simple structure and is inexpensive, so it can be used in retail stores to crush empty cans each time they are found, or by putting empty cans accumulated one day at a time. can. Since the empty can is crushed by pressing the circular parts at the upper and lower ends, the size of the flat surface after crushing becomes smaller, which has the advantage of facilitating subsequent processing operations. Furthermore, this process is so simple and safe that even children can do it, and it takes about 2.5 seconds to crush one empty can, and since it can be operated continuously, it doesn't take much time to process 100 cans.
