Abstract

PROBLEM TO BE SOLVED: To make it possible to safely shred cans even if a user puts his hand into a charging cylinder or small stone, etc. are charged into this cylinder by mischief by turning an arm provided with the charging cylinder at its front end onto a cutter duct and cutting the can by means of a pair of the cutters by the detection signal of a sensor for detecting the charging of the empty can. SOLUTION: A motor 3 is operated by the detection signal of the sensor 10 when the empty can (k) is charged from a feed port 2. The empty can charging cylinder 9 is then turned onto the cutter duct 11 by means of the arm 8 on the revolving shaft 5 connected to the bottom end of its output shaft to drop the empty can (k) onto the cutter duct 11. The dropped empty can (k) is cut by a pair of the cutters 12, 13 and the cut cans are housed into a chip housing box 15. The foreign matter such as small stone, charged from the feed port 2 falls from the vertical slit 9b of the empty can charging cylinder 9 and the spacing (h) at the bottom end of a guide plate 14 inclined toward the cutter duct 11, is blocked by the vertical projecting piece at the left and downward inclining end of the guide plate 14 and is housed into a foreign matter housing box 16 below this plate.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a housing, on which an input port 2 is formed. A motor 3 is disposed below the inlet 2 and has a clutch plate 4 fixed to the lower end of its output shaft.
Reference numeral 5 denotes a rotating shaft, which has a rubber plate 6 fixed to the upper end thereof, and is pressed against the clutch plate 4 by the pressure of a spring 7 so as to perform slip rotation with a constant load. Numeral 8 is an arm fixed to the rotary shaft 5 and is urged so that the empty can feeding cylinder 9 is fixed to the tip thereof and is always positioned below the feeding port 2. Reference numeral 10 denotes an empty can detection sensor attached near the upper end of the empty can input cylinder 9. The empty can feeding cylinder 9 is rotated by a predetermined angle by driving the motor 3. Reference numeral 11 denotes a cutter duct disposed at the rotating position, which is a pair of lower cutters 1
The empty cans K are designed to be dropped into Nos. 2 and 13. The lower end opening 9a of the empty can input cylinder 9 has an oblique shape.
facing the a at a constant interval h in front and in the cutter duct 11
A guide plate 14 that is inclined toward is provided. 14
Reference numeral a is a vertical protrusion that drops foreign matter on the side of the cutter duct 11 downward, 15 is a chip storage box, and 16 is a foreign matter storage box that drops from the guide plate 14.

Next, the operation will be described. When the empty can K is inserted from the input port 2, the sensor 10 detects it, the motor 3 is operated by the detection signal, the empty can insertion cylinder 9 is rotated on the cutter duct 11, and the empty can K is inserted into the cutter duct 1.
Fall on 1 The empty can K that has dropped is difficult to cut because it is a pair of lower cutters 12 and 13 and is cut.
5 When foreign matter such as pebbles is input from the input port 2, the vertical slit 9 of the empty can input cylinder 9 of the guide plate 14
b and the gap h at the lower end, and is blocked by the vertical projecting piece 14a at the lower left inclined end of the guide plate 14 to prevent the foreign matter storage box 1 below.
6 is stored.

When the width of the gap h between the lower end of the empty can feeding cylinder 9 and the guide plate 14 is too large, the empty can is greatly inclined in the empty can feeding cylinder 9 as shown in FIG. 6, and the lower end of the empty can K is engaged with the gap as shown in FIG. It stops and does not fall on the cutter duct 11.
When the lower end of the empty can feeding cylinder 9 is horizontal, the structure moves to the cutter duct in an arc shape, so that the gap h between the lower end of the empty can feeding barrel 9 and the inclined guide plate 14 becomes large, and the empty can may be locked in this gap. , A sensor for detecting the empty can insertion by arranging an arm rotatably on a shaft disposed on the lower side of the charging port, arranging a charging cylinder at the tip of the arm, and urging the arm so that it is always positioned below the charging port. The present invention is substantially the same as the guide plate 14 in that a driving device for rotating the arm on the cutter duct in response to the detection signal of the sensor is provided and a charging support plate is arranged to face the lower surface of the charging cylinder. Since there is an inclination of, there is substantially the same gap while the insertion cylinder 9 is rotating,
The empty can K is not tilted too much during rotation and is not locked in the gap h.
