Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container crushing device for crushing and collecting containers such as empty cans and bottles for the purpose of reusing resources.

[0002]

BACKGROUND OF THE INVENTION It has been proposed for a long time to reuse used beverage containers such as empty cans and empty bottles as resources, but since empty containers have a wide variety of materials such as iron and aluminum and are bulky, it is difficult to select them. The current situation is that transportation is troublesome and is not fully utilized.

Conventionally, in order to reduce the volume, it is known that the empty can is crushed by a tread plate or a pressing plate and that the pressing plate is driven by power, but the accuracy of material selection and the driving mechanism of the pressing plate are known. However, if uncrushable stones are mixed in, damage to the electric motor and drive mechanism will be fatal.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is that the drive mechanism is simple and reasonable, safe against overload, and the crushed empty container is efficiently magnetically sorted and collected. An object is to provide a container crushing device that discharges into a box.

[0005]

In order to achieve the above object, the structure of the present invention fixes the side wall plate to the machine frame, while the lower end portion of the pressing plate facing the side wall plate can swing left and right by the support shaft. The arms are connected to the front and rear ends of the output rotary shaft of the speed reducer connected to the electric motor, and a pair of front and rear links are connected to each arm and the upper end of the pressing plate, and an empty container is provided above the pressing plate. The hopper that slides down the magnetic sorting drum is arranged below the pressing plate.

[0006]

According to the present invention, empty cans thrown into the hopper are
One by one or one row is fed between the immovable side wall plate and the swingable pressing plate, and is crushed as the pressing plate swings. When the crushed iron empty can is released from the pressing plate, it is adsorbed by the stationary magnet (preferably permanent magnet) on the peripheral surface of the rotating drum and sent out to the side recovery box, and the aluminum empty can Is dropped into the collection box directly below.

A prime mover with a speed reducer that swings a pressing plate is fixedly supported by an overload prevention plate axially supported substantially parallel to the pressing plate. With the tilting against the spring force of the pressure plate, it retracts from the pressure plate, escapes the crushing action of the pressure plate, and avoids damage to the drive mechanism and the electric motor.

The output rotation shaft of the speed reducer 31 extends in the front-rear direction (direction perpendicular to the paper surface), while the main shaft of the electric motor 43 extends in the vertical direction, and both are rotationally coupled via a reduction gear. The rotation of the output rotary shaft of the speed reducer 31 is transmitted to the drum 52 through the chain wheel integrated with the disc 32, the endless chain 44, the intermediate chain wheel 48, the endless chain 49, and the chain wheel 50.

The drum 52 made of a non-magnetic material such as stainless steel cooperates with a plurality of magnets 54 (FIG. 2) arranged in the inner space to crush the space between the side wall plate 4 and the pressing plate 12. Can 2
Magnetically sort. That is, the iron empty can 2 falling from between the side wall plate 4 and the pressing plate 12 is attracted to the outer peripheral surface of the drum 52 and moves to the left side, and the magnetic field of the magnet 54 does not reach the lower part of the drum. It is thrown away from 52 and thrown into the recovery box 61. On the other hand, the aluminum empty can falls right below, slides along the right wall of the roof-shaped distribution plate 60, and is thrown into the collection box 62. Preferably, a flexible plate 56 made of, for example, rubber is hung and supported above the distribution plate 60 of the machine frame so that the aluminum empty can 2 is not flipped to the left.

As shown concretely in FIGS.
The pressing plate 12 supported by the machine frame is provided with an inclined plate portion 12b at a lower portion of a plate portion parallel to the side wall plate 4 for crushing the empty can 2 and an inclined plate portion 12a at an upper portion thereof, and the back and front sides thereof are moved forward and backward. It is reinforced by a pair of ribs 15. The lower edge of the inclined plate portion 12a projects laterally and extends in the front-rear direction.
Is formed. An anti-slip ridge 13 is also connected to the upper end of the inclined plate portion 12a.

A pair of front and rear ribs 15 is a pin 16 in the front and rear direction.
Thus, the link 35 is connected to the bifurcated joint 35a (FIG. 3). The electric motor 43 that drives the pressing plate 12 is the speed reducer 3

Are supported by an overload prevention plate 37 by a plurality of bolts 36. The lower end of the overload prevention plate 37 is a support shaft 38 in the front-back direction.
While being tiltably supported by the machine frame, the upper end portion is pressed against the beam 41 in the front-rear direction by the force of the spring 40. That is, the bolts 42 supported by the beams 41 are attached to the overload prevention plate 3
A spring 40, which penetrates 7 and extends in the opposite direction to the pressing plate 12, that is, to the left, is wound around a bolt 42 and is inserted between a seat plate 39 and an overload prevention plate 37 which are regulated by nuts.

The output rotary shaft 33 of the speed reducer 31 is connected at both ends with a disk 32 which functions as a crank arm, and the left end of the above-mentioned link 35 is connected to the peripheral edge of the disk 32 by a pin 34. An endless chain 44 is laid between the chain wheel integrated with the disc 32 and the chain wheel 47 of the intermediate shaft 46, and an endless chain 49 is laid between the chain wheel 48 and the chain wheel 50 integrated with the drum 52. Be done. An intermediate shaft 46 connecting the chain wheels 47 and 48 is supported by the beam 24.

The drum 52, which constitutes the magnetic sorting mechanism, is disposed below the pressing plate 12 and is provided with a plurality of scraping ridges 53 extending in the axial direction on the outer peripheral surface thereof. A plurality of (three in the illustrated example) magnets 54 are arranged in the inner space of the drum 52.
The magnet 54 is arranged only in the right half of the drum 52 so that the magnetic poles facing the inner peripheral surface of the drum 52 are alternately different in the circumferential direction, and exerts an attractive force on the crushed empty can 2. To be done.

Next, the operation of the container crushing device according to the present invention will be described. Reduction gear 3 driven by electric motor 43
When the output rotating shaft 33 of No. 1 rotates in the direction of arrow x, the link 35 reciprocates left and right, and the pressing plate 12 approaches the side wall plate 4 with the supporting shaft 17 as the center and the position inclined to the left. It swings to and from (the position indicated by the chain line). The vertical dimension of the pressing plate 12 is designed in relation to the outer diameter of the empty can 2, and when the pressing plate 12 is tilted to the left, the hopper 10 of the feeding section A is moved.
One of the empty cans 2 extends along the inclined plate 3 of the side wall plate 4 and the pressing plate 1.
I fall between two. When the pressing plate 12 swings clockwise, one empty can 2 is pressed against the side wall plate 4 by the pressing plate 12 and flattened.

At this time, the movement in which the empty can 2 tries to slide upward from between the pressing plate 12 and the side wall plate 4 is caused by the anti-slip protrusions 14.
Blocked by. When the pressing plate 12 swings counterclockwise, the crushed empty can 2 is released from between the pressing plate 12 and the side wall plate 4, and falls along the inclined plate portion 12b. At this time, the inclined plate portion 12b and the side wall plate 4 are substantially parallel to each other and have a wide gap, so that the empty can 2 is guided so as to slide downward. At the same time, the inclined plate portion 12a receives the next empty can 2 from the hopper 10 and guides it between the pressing plate 12 and the side wall plate 4.

The crushed iron empty can 2 is attracted to the outer peripheral surface of the rotating drum 52 by the magnet 54 while falling, and when it makes a half turn, it is moved away from the magnet 54 and scraped off.
It is scraped off into the collection box 61 by 3. The aluminum can 2 drops along the right wall of the distribution plate 60 into the collection box 62. The flexible plate 56 prevents the aluminum can 2 from bouncing to the left.

When a non-crushable foreign substance such as stone falls between the pressing plate 12 and the side wall plate 4, the link 35 is pressed by the link 35.
The force for pressing 2 against the side wall plate 4 is made ineffective by counterclockwise rotation of the overload prevention plate 37 about the support shaft 38 against the force of the spring 40. That is, the speed reducer 3
1 moves backward to the left, and the pressing plate 12 is not rocked. At this time, the circuit breaker that detects the overload current of the electric motor 43 opens,
The overload operation of the electric motor 43 is prevented, and an alarm device (not shown) sounds.

[0020]

As described above, according to the present invention, while the side wall plate is fixed to the machine frame, the lower end of the pressing plate facing the side wall plate is swingably supported by the support shaft and connected to the electric motor. Arms are respectively connected to both ends of the output rotation shaft of, and a pair of links are connected between each arm and the upper end of the pressing plate, and a hopper for dropping the empty can above the pressing plate is provided below the pressing plate. Since the magnetic sorting drum is arranged in the, the drive mechanism is simple and reasonably easy in that the pressing plate is rocked by a pair of front and rear links.
The crushed empty cans are efficiently magnetically sorted and put into the collection box.

Since the electric motor with reduction gear is supported by the overload prevention plate, when a foreign matter that cannot be crushed is introduced, the electric motor with reduction gear retracts together with the overload prevention plate from the pressing plate to prevent the motor from overloading. The load operation can be reliably prevented.

Since the magnetic selection drum having scraped ridges is arranged below the pressing plate and the stationary magnet is arranged in the inner space of the drum, it is necessary to drive the drum in synchronization with the swing of the pressing plate. Instead, the crushed iron empty can is surely adsorbed to the drum and moves to the side, and even if the iron empty can remains on the lower peripheral surface of the drum while sliding relatively, it scrapes off. It will be scraped off securely by the strip and will not interfere with or collide with the succeeding empty can and fall into the aluminum empty can.
