Abstract

PURPOSE:To simplify the constitution, to reduce fault and to prevent biting of an empty can by arranging guide part setting a cam follower arranged in rotating body on a movable pressing table. CONSTITUTION:By transmitting output of a motor 23, the rotating body 24 is rotated and following this, the cam follower 25 is rotated. Then, the cam follower 25 is shifted in the guide part 20 crossing at right angle to sliding direction of the movable pressing table 12 in the longitudinal direction thereof. Then, the shifting displacement to the side direction of the cam follower 25 is absorbed into the guide part 20, and the movable pressing table 12 is linearly reciprocated in the fixed pressing table 11. In such a way, control of advancing/ retreating movement of the movable pressing table 12 can be executed only with revolution of the motor 23, and the constitution is simplified and the fault is reduced. Further, as circle movement of the cam follower 25 is changed into linear movement of the movable pressing table 12, the movable pressing table 12 is shifted at high speed and the workability is improved and at the time of abutting on the fixed pressing table 11, as both tables slowly abut, the pressure torque of the movable pressing table 12 is large and the empty can be surely crushed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a press device for an empty can recovery machine.

[Prior Art] Conventionally, there has been known a press device for an empty can recovery machine that collects empty cans and crushes them one by one into a plate shape.

As shown in FIG. 4, the press device 1 of the empty can recovery machine includes a movable press table 3 that is slidable inside a box-shaped fixed press table 2. As shown in FIG. The fixed press stand 2 is set higher in height than the empty cans 4, and has an intake port 5 for the empty cans 4 on the upper surface and an outlet 6 on the lower surface. The discharge port 6 has an elongated opening so that when the empty can 4 is taken in, it does not fall out, but is discharged after being crushed.

On the other hand, the movable press table 3 reciprocates in a straight line within the fixed press table 2 while sliding a guide roller 7 rotatably provided on the side edge, so that the end surface 3a is aligned with the end surface 2a of the fixed press table 2.
It is designed to come into contact with. Furthermore, movable press table 3
A telescopic shaft 9 connected to a drive source 8 is engaged with the rear surface of the press 9. The drive source 8 moves the movable press table 3 in two directions: forward and backward.

In the conventional example as described above, when the empty can 4 is taken into the fixed press stand 2 through the intake port 5, the drive source 8 is activated, the shaft 9 is moved away, and the movable press stand 3 is moved forward. Then, the empty can is sandwiched between the end surface 2a of the fixed press table 2 and the end surface 3b of the movable press table 3, crushed into a plate shape h, and discharged from the discharge port 6.

Then, the drive source 8 operates again to retract the shaft 9,
The movable press table 3 is moved back.

[Problems to be Solved by the Invention] However, the above conventional techniques have the following problems.

That is, in the conventional example, since the movable press table 3 slides back and forth, a drive means for controlling the two directions of forward movement and backward movement is required. As a result, the configuration becomes complicated, which may lead to malfunctions.

Furthermore, in the conventional example, when the empty can 4 is crushed, the strong pressing force 1 causes the empty can 4 to stick to the fixed press table 2 or the movable press table 3, resulting in the empty can 4 being jammed. Something happened. Therefore, the next empty can 4 may not fit into the intake port 5 or may not be crushed.

The present invention was proposed in order to solve one or more of the problems, and the purpose is to provide an excellent product that has a simplified structure, fewer failures, and completely prevents empty cans from getting caught. An object of the present invention is to provide a press device for an empty can recovery machine.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the press device of the empty can recovery machine of the present invention has a press device on the top of the movable press table, the longitudinal direction of which is orthogonal to the sliding direction of the movable press table. The present invention is characterized in that a rotating body rotated by a motor is arranged above the movable press table, and a cam follower that moves within the guide part is provided near the outer periphery of the rotating body f.

Furthermore, the present invention provides a guide protrusion on the inner surface of the fixed press stand along the sliding direction of the movable press stand, a guide bowl fitted to the protrusion on the side edge of the movable press stand, and the fixed press stand. The present invention is characterized in that the guide protrusion has a missing portion at the tip of the inner side surface of the stand, which is slightly wider than the crushing margin of the empty can.

[Function] The function of the present invention having the above configuration is as follows.

That is, when the output of the motor is transmitted, the rotating body rotates, and the cam follower rotates accordingly.

The cam follower moves within a guide portion whose longitudinal direction is orthogonal to the sliding direction of the movable press table. At this time, the lateral displacement of the cam follower is absorbed by the guide portion, and the movable press table moves linearly and reciprocally within the fixed press table. As described above, in the present invention, it is possible to control the forward and backward movement of the movable press table only by rotating the motor, simplifying the configuration and reducing the number of failures. Moreover, the present invention converts the circular motion of the cam follower into linear motion of the movable press table.
The movable press table has high speed during movement and improves work efficiency. At the same time, when it comes into contact with the fixed press stand, it does so slowly, so the pressure torque of the movable press stand is large, making it possible to reliably and easily crush empty cans.

Furthermore, the present invention prevents the movable press stand from collapsing the empty cans even if they become stuck together when the movable press stand crushes the empty cans and retreats.
The inner fflJ surface of the fixed press table is equipped with a guide protrusion along the sliding direction of the movable press table and a missing part of the guide protrusion, which prevents empty cans from getting caught in the guide protrusions and getting caught. Can be done.

[Example] An example of the present invention as described above will be specifically described with reference to the drawings.

Note that the same reference numerals are given to the same members as in the prior art, and the description thereof will be omitted.
