Abstract

PURPOSE:To facilitate a waste can treating by detecting the waste can with a photoelectric sensor, driving a motor and collapsing the waste can at every pieces between a piston head and one side bumping wall by using oil hydraulic press of a pump directly connected. CONSTITUTION:At the time of charging the waste can K into a charging hole 2a, the can K is laid on a damper 10 and on the way of dropping it, the photoelectric sensor 4 is worked, to drive the motor 12. Then, by command of control device applied to oil hydraulic press with the pump 13 directly connected with the motor 12, the piston rod 6 is shifted forward, and the can K is pushed to the one side bumping wall 5a and collapsed. Material having wt. heavier than the waste can K compresses the spring 9 and drops to downside as non- treating state by opening the damper 10, and only the piston rod is reciprocated. When the can K is made to the collapsed can K, a forward selector valve 16 and a backward selector valve of the cylinder in an oil hydraulic mechanism 11 are reversely worked, and the piston rod is backed, to drop the can K downward. By this method, as the waste can K is collapsed and accepted at every pieces, the treatment thereof is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to an apparatus for automatically crushing empty beverage cans such as juice cans.

(Prior art) It is estimated that approximately 13.5 billion beverage cans are consumed annually.
There is still no definitive solution for its treatment outdoors.

There is still no end to the littering of waste, and despite the efforts of various efforts and great expense in all parts of the country, such as the collection of empty cans through unified beautification campaigns and attempts by local governments to introduce a deposit system. However, it has not yet had much effect, and what remains is a truly unreliable situation in which we rely on each individual's sense of public morals.

(Problem to be Solved by the Invention) In this current situation, the present invention automatically and silently removes empty cans by simply throwing them vertically into the inlet (in other words, in an action similar to dumping the can). To provide an automatic empty can processing device for compressing empty cans one by one, dropping them into a storage container below, and taking them out to the outside at any time.

[Structure of the Invention] (Example) To explain the following with reference to the embodiment shown in the drawings, 1 is a vertically elongated casing, the upper part of which is equipped with an empty can crusher A, and the lower part is formed into a storage space B for crushed pieces. .

Then, in the empty can crushing process IA, the upper end opening is inserted into the casing 1.
A charging cylinder 2 with a charging port 2a facing the outside is provided, and a photoelectric sensor 4 is arranged outside the side wall of the charging cylinder 2 in correspondence with a transparent hole 3 provided in the side wall of the charging cylinder 2. . Further, a crushing chamber 5 is provided below the charging tube 2, and a piston rod 6 that reciprocates toward the abutting wall 5a on one side faces into the crushing chamber 5, and has a length of empty cans at its tip. The piston head 7 exceeding the height is fixed, and the bottom wall portion sandwiched between the extreme protruding position of the piston head 7 and the one side abutting wall 5a is held in the crushing piece falling space 8, and the remaining bottom wall portion is held under a predetermined pressure. Roughly outside the crushing chamber 5, there is a hydraulic mechanism 11 for the piston rod 6 and an operating motor 12 connected to the photoelectric sensor 4, which is directly connected to the damper lO supported by a spring 9. It is equipped with a pump 13, a control panel 14, etc., and a storage space B at the bottom of the casing 1 is equipped with a replaceable storage container 18.

(Function) Now, when an empty can K is thrown into the input port 2a, the can is placed on the damper 10, and during the falling process, the photoelectric sensor 4 is activated to drive the motor 12, and the pump 13 directly connected to the can is placed on the damper 10. The piston rod 6 moves forward in response to a command from the control device that applies hydraulic pressure, and the can K hits the wall 5a and is crushed while being pressed against the wall 5a.

In the case of a heavy object such as an empty can, the spring 9 is compressed by the weight, the damper 10 is opened, and the object falls downward untreated, so although there is reciprocation of the piston rod 6, no operational failure occurs. .

When the can K is completely crushed into crushed pieces, the microswitch operates and the forward switching valve 16 and rear switching valve 17 provided in the cylinder of the hydraulic mechanism 11 operate in reverse, causing the oil in the cylinder to flow inside (the second right side in the figure), the piston rod 6 starts the bag, and the next instantaneous crushed piece falls downward from the falling space B, and the piston head 7 moves to the next empty can K.
When the output contact of the relay circuit is opened by the action of a magnetic switch (not shown), the motor 12
stops.

When an empty can K is subsequently introduced, the motor 12 is activated again in the same manner as before, and the crushing process is started.

In this way, the crushing operation is repeated continuously or intermittently every time the material is charged.

[Effects of the Invention] As described above, the present invention captures the can body with the photoelectric sensor 4 by feeding from the vertical direction, which is similar to the operation of discarding the waste, and silently releases one can body by the piston operation using an automatic control mechanism. The device is designed to be flattened and dropped into a storage container below each time, and then taken out to the outside at any time, so the loading operation is very natural, and the user is not required to perform any other actions other than loading (for example, opening the lid). etc.), it is inevitable that it will be used without any resistance, and it can contribute to the prevention of empty can pollution.

Also, in terms of operation, foreign objects that are heavier than empty cans are sorted out by the damper to avoid crushing action, so it is possible to avoid operational failures as much as possible.

Roughly crushed piece 1 (is flattened into a rectangular shape with a thickness of about 2 mm by the piston action), so it is convenient to process and handle after falling, and it is possible to improve the storage efficiency of falling space B. can.
