Abstract

PROBLEM TO BE SOLVED: To make it possible to surely cut the corner parts of empty cans by means of cutters regardless of the sizes of the empty cans by disposing guide plates facing each other above a pair of the cutters, mounting an oscillation plate between these guide plates and disposing a lever for pressing the upper parts of the empty cans fed into the machine downward. SOLUTION: The empty can charged from a feed port is transported into the spacing between the guide plates 3 and 4. The pressing lever 10 is swiveled and turned by a pressing solenoid when this can is detected by a sensor 22. The upper part of the empty can K falling onto the cutters 1, 2 is then pressed by pressing disks 13 to 15. The oscillation plate 5 is then oscillated inward by a spring 9 and the empty can K is pressed from the side, by which the corner parts of the base of the empty can K are bitten between the cutters 1, 2 and the empty can K is cut by the cutters 1, 2. A discharge solenoid 18 operates and the uncut empty can, foreign matter, etc. are discharged outside via the oscillation plate 5 when the uncut empty can, foreign matter, etc. remain as they are on the cutters 1, 2 for the specified time or longer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can shredder device in which empty cans are inserted from an input port on the upper part of a housing and cut by a cutter.

[0002]

2. Description of the Related Art In a conventional empty can shredder device, an empty can is dropped into a cutter duct from an input port and cut by a cutter below the cutter duct.

[0003]

In the above prior art, there is a problem that a crushed empty can is caught in the middle of the cutter duct, and when pushed by hand, the hand comes into contact with the cutter and is damaged. . Further, even if an uncrushable empty can is dropped on the cutter, it is difficult for the cutter to stick to the cutter, and if the operator pushes it by hand to force it, the hand comes into contact with the cutter and is damaged.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to mount a guide plate facing the upper side of a pair of cutters and an oscillating plate in one of the gaps. It is characterized in that a lever for urging inwardly and pushing down an upper part of the empty can carried in above the gap is arranged, and a solenoid for operating the lever and an empty can detection sensor are arranged.

[0005]

Embodiments of the present invention will be described in detail with reference to the drawings. Opposed guide plates 3 and 4 having a gap in which an empty can falls are disposed above a pair of cutters 1 and 2 in the housing, and a swing plate 5 is disposed in one of the gaps and fixed to the upper portion. The pin 6 is pivotally attached to the guide plates 3 and 4,
The pin 7 fixed to the middle portion is loosely fitted in the circular arc groove 8 of the guide plate 4, the other end of the spring 9 having one end fixed to the guide plate 4 is locked to the pin 7, and the rocking plate 5 causes the guide plate 3 to move. , 4 are biased inward. A pressing lever 10 is arranged along the inner surface of the guide plate 3, one end of which is pivotally attached to the guide plate 3 so as to be vertically movable, and a short rod 11 is pivotally attached to the tip thereof, and the horizontal bar 1 is attached to the tip thereof.
2 is pivotally attached and three pressing disks 13, 14, 15 are attached. Reference numeral 16 is a pressing solenoid that presses the pressing lever 10 fixed to the outer surface of the guide plate 3 downward, and its plunger 17 is attached to the pressing lever 10. The discharge solenoid 18 is fixed to the surface of the guide plate 4, and the tip of the plunger 19 is attached to the pin 20 on one side of the swing plate 5. Reference numeral 22 denotes a sensor that is conveyed onto the cutters 1 and 2 and detects an object. Reference numeral 23 is a switch for detecting that the pressing lever 10 has moved down to the final position.
The discharge solenoid 18 is operated by detecting that the empty can has been present for a longer time than the time when the empty can falls into the cutters 1 and 2 and is cut.

Next, the operation will be described. An empty can is loaded from a loading port of a casing (not shown), and the empty can is conveyed to a gap between the guide plates 3 and 4. This transportation may be carried out by dropping directly from the charging port, or the empty can dropped from the charging port may be carried by another means. That point is outside the scope of the present invention. The empty can K inserted from the inlet is the guide plate 3,
The sensor 22 detects when the paper is conveyed into the container 4 and drops, and the detection solenoid 16 operates according to the detection signal to press the upper part of the empty can K dropped on the cutters 1 and 2 with the pressing disks 13, 14 and 15 as shown in FIG. The swing plate 5 swings inward by the spring 9 and pushes the empty can K from the side. As a result, the corners of the bottom of the empty can K are difficult to cut with the cutters 1 and 2. Is cut by. If empty cans, foreign substances, etc. that are not cut remain on the cutters 1 and 2 for a certain period of time without being pressed, the discharge solenoid 18 is actuated and the swing plate 5 is pushed outward and opened. To discharge.

[0007]

According to the present invention, a guide plate facing the upper side of a pair of cutters and a swinging plate attached to one of the gaps are urged inward by an elastic body, and are carried above the gap. Since a lever that presses the upper part of the empty can downward is provided, and a solenoid for operating the lever and an empty can detection sensor are provided,
Regardless of the size of the empty can, you can cut the corner of the bottom of the empty can with a cutter that is hard to hit.
