Field of the Invention The present invention relates to an empty can crushing device for crushing and reducing the volume of used empty cans one by one in order to promote the efficiency of resource reuse and environmental protection, and particularly to safety and maintenance. The present invention relates to an empty can crushing device.

[0002]

2. Description of the Related Art Conventionally, various empty can processing devices have been developed as a device for crushing empty cans of beer and soft drinks.
It is put to practical use. In the empty can crushing device that crushes (presses) the empty can in cooperation with the movable pressing body and the fixed plate, a device with safety measures such that the hands cannot be inserted into the compression chamber of the device is required. Has been. A device related to this type of device is, for example, Japanese Utility Model Publication No. 62-45.
No. 835 and Jikken 1-10154 are known. In the device disclosed in Japanese Utility Model Publication No. 62-45835, a distance between the charging port and the pressing part is set to some extent and a door plate of the charging port is opened so that a hand cannot be inserted into the pressing part from the charging port. In this case, the receiving port can be closed by the receiving plate. In addition, a micro switch is provided which activates the pressing device when the door plate is closed. When the micro switch is turned on, it is excited to fix the rotary shaft of the door plate and lock the opening of the door plate during the press operation. Also, fairness 1-10
In the device described in Japanese Patent No. 154, an upper lid that opens and closes a charging port and a lower lid that is located below the upper lid and temporarily holds an empty can are provided, and the upper and lower lids are placed under spring action. Supports are rotatably supported, and support cams that can be joined to each other are fixed to both lids.When the upper lid is open, the lower lid is closed and the press part is closed, and the upper lid is closed. At this time, the lower lid is opened and the empty can that has been temporarily held is dropped into the press section. Further, a pressing element that presses the lower lid in the closing direction when the pressing plate moves forward is fixed to the pressing plate, and prevents the lower lid opening operation during the pressing operation.

[0003]

In the above-mentioned prior art, an empty can is charged through the charging port provided in the upper part of the apparatus, and the empty can is dropped into the compression chamber through the path to the compression chamber. After compression, a thin and flatly compressed empty can passes through a narrow path that matches the thickness, discharges to the outlet, goes out, or is stored in a collection box. . In such a device, when foreign matter other than an empty can that is not crushed is thrown into the compression chamber due to mischief or the like, it will not be crushed and thinned, so that it may pass through a narrow path portion from the compression chamber to the outlet. It cannot be done and either stops in the compression chamber or gets caught in the middle of the path. In addition, even if it is originally compressible, if the next one or several cans are loaded without operating the compression switch with one empty can still inserted, the input will not be completely crushed and crushed. Something that does not stay in the compression chamber or gets caught in the middle of the path. This happens when,
Unless the device itself is disassembled and repaired, the clogged object cannot be taken out and the device cannot be used again. However, in order to avoid disassembling the device, it is not possible to ensure safety if the device has a structure in which a jammed input can be taken out. This way my hands and fingers are crushed

It has to be structured. On the other hand, put your hand or finger inside the device.
If a structure that does not block the
"Safety" that you can't take it out easily
And there is a trade-off in terms of "conservability". Also,
In an empty can crushing device that crushes empty cans and the device itself also serves as a collection box for empty cans, the device is used as a collection box for empty cans, so the collection box part is filled with empty cans. However, it was left as it was, and as a result, the crushed empty can was clogged up to the path part from the compression chamber to the outlet,
May cause equipment failure. Also, since the collection box is considered as a kind of trash can, if the empty can crushing device is integrated with the collection box, foreign matter other than empty cans will be thrown in.
Alternatively, there is a high risk of failure due to irresponsible use . In addition, like the conventional device, when the press part is clogged and the device becomes inoperable, an opening / closing door is provided to take out this, and an electrical switch (limit switch) interlocking with the opening / closing door is used to open the door. If the press operation is not performed during opening (inserting a hand), the electrical switch malfunctions due to welding or short circuit, the safety device is released, and the compression mechanism operates to catch your hand or finger. There is a danger that Also, if the input is frequently clogged in the equipment, open the door to open the limit switch.
Secure the safety mechanism by fixing the tape with adhesive tape, etc.
A monster that dares to kill and uses it in a dangerous state to crush hands and fingers
There is a case to lose myself. This case is when operating an industrial machine
Typical putter often seen in industrial accidents
And much less than unspecified safety education
Such an accident may occur in the empty can crushing device intended for the general public . A first object of the present invention is to
An object of the present invention is to provide an empty can crushing device that solves such problems and has both "safety" and "maintenance". That is, not only the safety during normal operation but also the safety is ensured even when the operator intentionally cancels the safety function when an abnormality occurs in the device. A second object of the present invention is to make an input port-a path portion-a compression chamber-
The structure is not to use the path portion-take-out port (conventional structure), but to have a structure in which an empty can is directly inserted into the compression chamber and directly taken out from the compression chamber. A third object of the present invention is to make the recovery box independent of the empty can crushing device and to have only the function of crushing the empty can. A fourth object of the present invention is to reduce the number of device failures and facilitate maintenance such as removal of stains due to residual liquid. The fifth object of the present invention is to
~ It is to achieve the fourth object and to realize small size and low cost (small number of parts).

[0004]

In order to achieve the above object, an empty can crushing device of the present invention is provided with a compression chamber (20 in FIG. 1) for crushing an empty can with a fixed plate and a movable pressing plate.

Even if is inserted, the movable pressing plate is prevented from physically moving, and safety is secured. On the other hand, when the door plate is closed, the actuator joined to the rotary shaft of the door plate pushes the micro switch installed on the upper part of the inner wall surface adjacent to the compression chamber to electrically notify that the door plate is closed. Detects and activates the main switch. Therefore, the main switch does not operate when the door plate is not completely closed. When the movable pressing plate starts moving when the door plate is completely closed and the main switch is turned on, the movable pressing plate rides on the empty can stand, so even if there is a failure or malfunction in the electric circuit, the door plate will remain The door cannot be opened while it is physically locked and the movable pressing plate is moving, which ensures safety. Further, by integrating the compression chamber, the empty can stand and the stopper part, or integrating the compression chamber and the stopper part, it is possible to realize a small size and a low cost with a minimum number of parts. Furthermore, by making the recovery box independent of the empty can crushing device and directly inserting and taking out the empty can into the compression chamber, there are few device failures,
Maintenance such as removal of dirt due to residual liquid is easy.
