Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a waste compression processing device that stores and compresses waste such as paper cups and empty cans for various beverages, or papers. .

[Conventional technology]

Traditionally, this type of waste compression processing equipment has a waste storage container built into the lower part of the equipment body that can be freely pulled out, and a press body that is movable up and down above the container. Constructed to compress waste such as paper cups and empty cans stored in the container by lowering the container using a screw rod or the like as a guide by driving, or by pushing it down by a fluid pressure cylinder. This structure is widely used.

[The problem that the idea aims to solve]

However, if the press body is configured to be raised and lowered by a fluid pressure cylinder, an extra space is required to accommodate the fluid pressure cylinder, which increases the size of the entire device, which may cause problems in handling and installation location. There is.

On the other hand, even when the press body is raised and lowered by motor drive, the same problems as above arise because a space is required for the installation of the motor, and furthermore, the power is transmitted from the motor to the screw rod. Chains are commonly used as a means of cleaning, which generates noise and harms the environment.

In addition, the press body is configured to always descend to a certain distance and compress the waste in the container, so it can be used in cases where items that are difficult to compress are being disposed of, or when an unnecessarily large amount of waste is being disposed of. When the motor is housed, there is a risk of not only a large load being applied to the motor and burnout, but also damage to the container or other parts.

Furthermore, if you try to open the lid and put in the waste while pressing the waste stored in the container, it is extremely dangerous because the press body is descending.
In particular, if the container is pulled out unexpectedly, there is a risk that the container will be damaged by the compressive force of the press body and that a major accident may occur due to the impact force generated at that time.

Further, a bag body such as a vinyl bag is placed inside the container, and the opening edge of the bag body is folded back along the mouth edge of the container.
However, if the lock is released during pressing or the bag is deformed, it will not only take time to remove the compressed waste from the container, but also make it difficult to remove it smoothly. There was a problem that people's clothes were soiled.

The present invention provides a waste compression treatment apparatus aimed at completely solving these problems.

[Means to solve the problem]

In order to achieve the above object, the waste compression treatment apparatus of the present invention rotatably supports vertical screw rods 2, 2 on both sides of the box-shaped main body 1. Threaded cylinders 4, 4 fixed to the outer surfaces of both sides of the press body 3 are screwed together, and a drive motor 6 is disposed at the upper end of the body 1, and the rotation of the motor 6 is transmitted through a transmission belt 9. vertical screw rod 2
In a waste compression processing apparatus configured to move the press body 3 up and down by transmitting a signal to It is formed into a hollow press body 3 with an open upper end, so that the motor 6 can be accommodated in the hollow interior 5, and when the compression pressure by the press body 3 reaches a certain pressure or more in the electric circuit of the motor 6, A current detecting means for detecting the current and stopping the motor 6 is provided, and furthermore, the waste storage container 11 is arranged so as to be tiltable toward the front of the main body 1, and the tilting is detected to stop the motor 6. Safety switch 20 to disable

Further, in the compression treatment apparatus configured as described above, a rectangular hanging auxiliary sheet 21 having handles 22, 22 at both side ends is laid in the waste storage container 11 from the inner bottom surface to the inner surfaces on both sides. A waste storage bag 12 is disposed on this auxiliary sheet 21, and the opening periphery of the bag 12 is connected to the waste storage container 11.
The handles 22, 22 of the auxiliary sheet 21 are configured to protrude outward from both sides of the open end of the waste storage container 11.

[Effect]

When the press body 3 is located at the rising end, the motor 6 is housed in the press body 3 in a recessed state, so that there is no need for installation space for the motor 6 separate from the press body 3, and the entire apparatus is is compact.

After an appropriate amount of waste is stored in the waste storage container 11, when the motor 6 is activated, the rotational force is quietly transmitted from the transmission belt 9 to the vertical screw rod 2.
As the vertical screw rod 2 rotates, the press body 3 descends and compresses the waste in the container 11.

At this time, if waste that is difficult to compress or a large amount of waste is being stored, the press body
When a pressure higher than a certain compression force is generated in the motor 6, an overcurrent flows to the motor 6 side, and this current is detected to immediately stop the motor 6, and the press body 3
Stop at that position and then raise it.

In addition, if an attempt is made to unexpectedly pull out the waste storage container 11 from the main body 1 while the press body 3 is lowering, the safety switch 20 detects the movement of the container 7 and disables the motor 6, and the press body 3 is lowered. This is to stop the

After the waste in container 11 is compressed, container 1
1 is rotated toward the front of the main body 1 to expose it to the outside, and when the handles 22, 22 of the auxiliary sheet 21 protruding from both sides of the open end of the container 11 are grasped and lifted, the compressed waste is removed. The bag body 12 containing the auxiliary sheet 21 is taken out from the container 11 as a whole while being wrapped by the auxiliary sheet 21,
While the auxiliary sheet 21 is unfolded and only the waste storage bag 12 is disposed of at an appropriate disposal site, the auxiliary sheet 21 is placed inside the container 11 and used again.

To describe the operation of the waste compression treatment apparatus in the embodiment configured as above, first, the auxiliary sheet 21 is laid in the waste storage container 11 from the inner bottom surface along both inner surfaces. After the handles 22, 22 are made to hang outward from the opening edges on both sides of the container 11, the bag 12 is placed inside the container 11 so as to be placed on the auxiliary sheet 21. Then, the opening edge is folded back and locked to the opening edge of the container 11, and fixed with a presser metal fitting 13.

In this state, the container 11 is installed on the inner bottom surface of the main body 1 along the back surface of the door body 14.

Use the transparent opening/closing plate 1 to dispose of waste such as paper cups and empty cans.
9 is opened and put into the container 11, and when a sufficient amount of waste is contained in the container 11, the start button 24 of the motor 6 is pressed to compress the waste.

To explain this state based on the electrical circuit diagram shown in Fig. 5, when the start button 24 is pressed, the relay starts.

The auxiliary sheet 21 is placed inside the container 11 and used again, while only the auxiliary sheet 21 is disposed of at an appropriate disposal site.

[Effect of idea]

As described above, according to the waste compression treatment apparatus of the present invention, since the driving means for raising and lowering the press body 3 along the vertical screw rods 2, 2 is carried out by the transmission belt 9 from the motor 6, no noise is generated. Of course, the press body 3 can be raised and lowered quietly without any noise, and since the press body 3 is formed into a hollow body with an open upper end and the motor 6 can be accommodated in the hollow interior 5, the press body 3 can be moved up and down at the upper limit position. When the motor 6 is stopped, the motor 6 is housed in the press body 3. Therefore, there is no need for a separate installation space for the motor 6, and the height and volume of the main body 1 can be reduced to make it compact. It's something you get.

Furthermore, a container 11 arranged on the inner bottom surface of the main body 1
When the press body 3 compresses the waste in the press body 3, a detection means is provided to detect an overcurrent and stop the motor 6 when the compression pressure by the press body 3 reaches a certain pressure or more. Therefore, if the container contains items that are difficult to compress or a larger amount of waste than necessary, the press body 3 should not be lowered to its lower limit, but stopped midway, and then raised. Therefore, seizure of the motor 6 and damage to the container 11 and other parts can be prevented.

Furthermore, when the waste storage container 11 is pulled out from inside the main body 1, the safety switch 20 detects this and disables the motor 6, so that the container 11 can be handled safely.

Further, a rectangular hanging auxiliary sheet 21 having handles 22, 22 at both ends is laid in the waste storage container 11 from the inner bottom surface to the inner surfaces on both sides,
A waste storage bag body 12 is arranged on this auxiliary sheet 21, and the opening periphery of the bag body 12 is connected to the waste storage container 1.
Since the handles 22, 22 of the auxiliary sheet 21 are configured to protrude outward from both sides of the open end of the waste storage container 11, the waste is stored in a compressed state. Bag body 1
2 from the container 11, the auxiliary sheet 21
By grasping and pulling out the handles 22, 22, the bag 12 can be taken out easily and quickly without touching the bag 12, and at that time, the bag 12 is held by the auxiliary sheet 21. This allows the bag 12 to be removed from the container 11 without the dirt attached to the bag 12 getting on your hands or clothes. After the bag 12 containing the waste is disposed of, the auxiliary sheet 21 can be put back into the container 11 and used again.
