Abstract

PROBLEM TO BE SOLVED: To solve such problems given by a conventional empty can press as that: pressed figures are not uniform,; the empty cans become bulky due to their non-uniform thickness after pressing; and recovering, transportation, and administration in a recycling work are difficult. SOLUTION: An empty can is fed between a press fixing plate (113) and a press slider (110), a pressing pressure is exerted in three stages, the pressed thickness of the empty can is uniformized, and the pressed empty can is discharged through a discharge port (112) provided on a base bench (114). Thus the pressing capacity is remarkably improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw feed horizontal empty can press using the force of a screw.

[0002]

2. Description of the Related Art Conventional empty can presses include various empty can presses, such as stepping, and the pressing direction and the pressing pressure vary, so the shape of the empty can after pressing varies. It was an empty can crusher factor.

[0003]

In the conventional empty can press machine, the shape of the empty can after pressing is also different due to the difference in the pressing direction and the pressing pressure, and the press thickness is not uniform. There were many difficulties in recovery, transportation, and management, and the press ability was extremely low.

[0004]

In order to achieve the above-mentioned object, the present invention is to perform pressing so that a uniform thickness is applied by applying a uniform pressure from a lateral direction, which is a weak point of an empty can, and a press processing capacity. Measure improvement.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In FIG. 3, when the press slider (110) is at the standby origin position, the empty can A
Is loaded from above, and the press slider (110) is slid toward the press fixing plate (113) (in the direction of arrow A) to press the empty can.

Thereafter, the press slider (110) is reversely slid (in the direction of arrow B) to return to the standby origin position, so that the empty can pressed by the press fixing plate (113) and the press slider (110) is moved. The press pressure is weakened, and the empty can A is lifted off the air and dropped by its own weight to form a hole in the base (114).
It is discharged out of the press as empty can A 'through 2).

In the embodiment, as shown in FIGS. 5 and 6, an end sensor (1) for detecting the movement position of the press slider (110) is used.
19), constant velocity sensor (120), deceleration sensor (12)
1) It has four position detection sensors, an origin sensor (122).

After the empty can A is charged into the empty can press, the drive motor (101) is controlled as shown in FIG. First, the drive motor (101) is started, and the speed of the drive motor (101) is accelerated to the maximum speed in order to press the empty can A to 65 to 85%, and the empty can A is extended in all directions. Therefore, the deceleration control operation is performed from the time when the deceleration sensor (121) is detected to the time when the constant speed sensor (120) is detected.

Then, in order to eliminate the rebound phenomenon of the press material, that is, the springback phenomenon, a low-speed control operation of the drive motor (101) is performed from the detection of the constant velocity sensor (120) to the detection of the end sensor (119). As a result, the empty can A is pressed to a uniform thickness.

Thereafter, the rotation of the drive motor (101) is reversed, an acceleration control operation is performed, and the operation is stopped by detecting the origin sensor (122). At this time, the drive motor (1
01), the pressing pressure of the empty can A previously pressed between the press fixing plate (113) and the press slider (110) is weakened, and the empty can A comes off and floats in the air. It is discharged out of the press as an empty can A 'through a discharge hole (112) formed by making a hole in (114).

[0011]

Since the present invention has the above-described steps, the conventional empty can press has tended to crush the empty can, but the empty can press according to the present invention has an empty can crush. Since the press can be used, the thickness of the empty cans after pressing is uniform, and it is not bulky, so that collection, transportation and management can be properly arranged and stacked for recycling work. There was a remarkable effect that it became easier.

In addition, since the empty can A is discharged to the outside of the empty can press through the discharge hole by its own weight and dropped after the pressing of the empty can A, there is a remarkable effect on the press processing ability.

[0013] The empty can press is compact and compact, so it can be used exclusively for cans and can be incorporated into vending machines for selling bottles and cans. The original responsibility allows the collection of empty cans, and the collection rate of empty cans can be increased, thus inevitably increasing the resource reuse rate and inventing to contribute to the problem of empty cans throughout Japan. But also.
