Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an empty can processing apparatus that crushes a large number of empty cans using a press into a compressed block shape.

[Conventional technology]

Empty cans harm the environment if left as is, so it is desirable to collect and dispose of them.

This process is performed by compressing the empty cans into a block shape using a press in order to make them easier to transport after they are collected. Usually, an extraction type cylinder is used as a press device for processing empty cans.

[Problem to be solved by the invention]

By the way, in a press device for processing empty cans that employs a hydraulic cylinder system, when oil deteriorates over time, the pressing force decreases, so regular oil changes are required. Furthermore, since a large number of parts such as piping, control valves, and pumps are required in addition to hydraulic cylinders and pistons, the equipment tends to be large and the cost tends to increase due to an increase in the number of parts.

Furthermore, since failures are likely to occur in hydraulic system pipes, etc., it is necessary to maintain and manage them strictly.

The present invention has been made in view of the above points, and its purpose is to efficiently dispose of empty cans using a press method instead of the conventional cylinder method, and also to eliminate the need for oil changes and reduce maintenance management. It is an object of the present invention to provide an empty can processing device that is easy to use, reduces product cost, and makes the device simple and compact, and is easy to use.

[Means to solve the problem]

In order to achieve the above object, the present invention is configured as follows.

Hereinafter, in order to facilitate understanding of the content of the invention, reference numerals of the embodiments in the drawings (in particular, FIG. 1, FIG. 2, FIG. 3, and FIG. 5) will be cited and explained.

That is, the present invention provides a box having an internal space for accommodating and pressing a large number of cans Pi (shown in FIG. 2), and an empty can inlet 1a.
and an empty can press box 1 arranged horizontally and provided with an outlet 1b for taking out the empty can compression block P2 (shown in FIG. 3) after being pressed; The empty can pressing tool 6 is arranged, and the driving mechanism that moves the empty can pressing tool 6 back and forth converts the rotational force of the motor 5a into linear reciprocating motion using the gear 5b and screw rod 5d, as shown in FIG. Then press the empty can press tool 6.
and a gear type press drive mechanism 5 that transmits transmission to the press box 1, and the empty can pressing tool 6 is set to move while being guided by the inner surface of the press box 1.
As shown in FIG. 5, rolling elements 7 consisting of ball casters or rollers are provided on at least the left and right side surfaces 6b, 6c and the lower side surface 6d, and the rolling elements 7 contact the inner surface of the press box 1 to press the empty can. It serves as a structure to support the tool 6.

[Effect]

According to the present invention having such a configuration, when pressing empty cans P1, a large number of empty cans are put into the empty can pressing box 1, and then the motor 5a of the gear type press drive mechanism 5 is turned on. Operate in the forward rotation direction. The torque of the motor 5a is increased by the gear Sb, and the torque of the screw rod 5d is increased.
It is converted into a linear reciprocating motion and transmitted to the empty can pressing tool 6.

In response to this force, the empty can pressing tool 6 moves forward inside the press box 1 while crushing the empty can, and presses the empty can into a compression block P2.
generate. The compression block P2 is taken out from the press box after the operation is stopped.

The above is the basic operation of the present problem solving means. First, in the present invention, a gear type is adopted as the press egg movement mechanism 5, so unlike the conventional hydraulic cylinder type, hydraulic piping system parts are not required. The number of parts can be reduced, and the mechanical heeling system such as a gear mechanism and motor is simpler and more compact than a hydraulic cylinder system.

Further, the empty can pressing tool 6 that is reciprocated by the press drive machine Mt5 has at least left and right side surfaces 6b and 6c.
By disposing a rolling element 7 such as a ball caster or a roller on the lower side surface 6d, it is supported by this rolling element 7 and moves. As a result, the press box 1 can be smoothly moved on the inner surface, and the press load can be evenly applied via the press tool 6, thereby allowing the empty can compression work to be performed satisfactorily.

In addition, if such a rolling element 7 does not exist, in the gear drive system, the pressing tool 6 and the press box 1
The contact friction with the press tool 6 becomes too large, making it impossible to ensure smooth stroke motion of the press tool 6. Also, as a result, an even press load is not generated on the press tool 6, making it impossible to expect good press operation. .
