Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty can press using a motor, its structure and its safety.

[0002]

2. Description of the Related Art The structure of a conventional empty can press machine generally has a three-phase 200 V commercial power supply, and the press section is of a hydraulic, pneumatic cylinder or roller type and is large.

[0003]

Conventional empty can press machines are often used for business purposes, and the general public has no place where they can easily use them. was there.

The present invention is automatically activated when an empty can is inserted from an inlet regardless of age or the like, and is discharged and stopped after the empty can is pressed. Moreover, the object of the invention is to manufacture empty can presses having a safety device for stopping the cans and bottles containing the contents so that the hands, fingers, and the like cannot be put thereinto.

[0005]

In order to achieve the above object, in the empty can press according to the present invention, a charging door is provided at a charging port, and a door opening / closing switch and a magnet cylinder are attached beside the charging door. The balance plate is attached to the lower part of the box, and a detection sensor is attached to the input duct. A bearing rail and a press plate are attached to the base plate, and a table plate with a press plate and a drive motor attached is incorporated into the base plate, a discharge port is provided below the press section, a detection sensor is provided below the discharge port, and a door is opened and closed at the discharge door. A switch is attached.

[0006] The reason why the loading door is attached to the loading port is that when the empty can is loaded, the door is automatically activated so that a hand, a finger or the like cannot be put in. Therefore, the door is preferably closed with a magnet cylinder during the startup for safety. In addition, it is preferable to use a stainless steel plate because an empty can or the like comes into direct contact with the input door.

The purpose of the balance plate is to sort the empty cans and the cans or bottles containing the contents by weight. Therefore, it is preferable to use a material that is light and resistant to the impact of empty cans, and is made of an elastic body with a spring hinge.

[0008] The detection sensor attached to the charging duct is for detecting the charging of the empty can.
At least two are required considering medium and small. Further, the type of the detection sensor is preferably a transmission type photoelectric switch.

Since the press section is an important part, it is preferable that the press section is firmly welded firmly with a thick steel plate.

[0010] In addition, since a sound is generated when the empty can put into the press section falls, it is effective to attach a sound insulating rubber sheet or the like to the press section.

The driving motor mounted on the table plate is a general household power supply of 100 V AC, and a reduction gear is mounted on the motor shaft to form a low-rotation, high-torque type, and is incorporated in a rack gear mounted on the base plate. Press can produce the press section.

The bearing rail installed between the base plate and the table plate is effective for smoothly moving the reciprocating motion of the press section.

Further, the discharge port provided below the press section is provided at a press stop position since the empty can after the press is discharged by natural fall, and furthermore, the empty can and the discharge can be caught in the discharge port by a detection sensor attached below the discharge port. It is good to detect that the box is full.

It is good for safety that the discharge door is provided with a door opening / closing switch, and is stopped when the discharge door is opened during startup.

When an empty can is inserted from the input port of the empty can press configured as described above, it is selected by the balance plate, detected by the sensor of the input duct and dropped into the press section, and the input door is closed by the magnet cylinder, When the drive motor is started, the rotational motion is translated by the rack gear, and the empty can is pressed by the press plate attached to the table plate. The origin position of the table plate and the press stop position are determined by a detection sensor, and when the table plate returns to the origin position, the pressed empty cans fall into the discharge box. In addition, if the discharge door is opened during startup, it stops, and if it is closed, it starts automatically.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. 1, 2, and 3, a base plate 13 to which a press plate 11 and a rack gear 25 are attached.
Is fixed to the frame 10. Further, the table board 13 on which the drive motor 1 having the press plate 3 and the reduction gear 2 mounted thereon is mounted on the rack gear 25 with the bearing rail 15 mounted on the base plate 13. Then, the charging port 6 is attached to the frame 10 and the magnet cylinder 7 is assembled with the charging door 5. The balance plate 4 is attached to the lower part of the input port 6 and then the input duct 9 is connected to the frame 1.
It is fixed to 0 and tightened with the holding pipe 50. After attaching the detection sensors 17 and 19, the discharge door 20 is attached to the frame 10 and the door open / close switch 23 is attached to the frame 10.

FIGS. 4A and 4B are external views of the balance plate 4. FIG. The material is made of ultra-thin metal and the ends are bent for reinforcement. The spring hinge uses the balance plate 4 as an elastic body, and has a purpose of selecting falling cans.

In the embodiment shown in FIG.
As a seesaw type centered on the point A of 7, the empty cans 34 inserted from the input port 30 fall in the falling directions 35 a, 35 b, 3
5c. The cans and bottles containing the contents fall over the holding pipe 32 and fall in the direction 35c.
Further, depending on the position where the balance plate 37 is dropped, the balance plate 37 falls in the drop direction 35b.

In the embodiment shown in FIG.
7 was used as a spring hinge as shown in FIGS. 3A and 3B, and a guide plate 50 was attached downward. The empty cans 44 introduced from the introduction port 40 fall in the falling directions 35d and 35e. Further, the cans and bottles containing the contents also fell in the falling direction 35e over the holding pipe 42.

[0020]

Since the present invention is configured as described above, it has the following effects.

Even if a can or a bottle containing the contents is mistakenly inserted by attaching a charging door to a charging port, holding a pipe, and mounting a balance plate, it can be selected and pressed.

Also, during startup, the loading door may be closed by the magnet cylinder for safety.

Further, the drive motor system and the press section can be easily manufactured because of their simple structures.

Since the pressed empty cans are discharged by a natural fall from the discharge port, no troublesome device is required.

Further, by attaching the discharge door, the safety is increased and the appearance is good.
