Description

AUTOMATIC SORTING COMPRESSION MACHINE FOR IRON, ALUMINUM CANS AND PLASTIC BOTTLES}

The present invention relates to an automatic sorting press for iron cans, aluminum cans and plastic bottles, and more particularly, to a device in which sorting work and storage space are significantly reduced to facilitate recycling.

Iron cans, aluminum cans and plastic bottles are the most common beverage containers. Conventional presses for recycling cans could only classify iron and aluminum cans, and plastic bottles could not. Thus, the three most common containers could not be sorted at the same time to facilitate the recycling procedure. In order to complete the sorting and crimping work, additional procedures via manual sorting must be carried out.

The main object of the present invention is to provide an automatic sorting press for iron cans, aluminum cans and plastic bottles, while plastic bottles are classified by electrical conductivity while iron cans and aluminum cans are classified by magnetic attraction. The containers are sorted and pressed at the same time. Thus, the sorting operation and the storage space are significantly reduced to facilitate the recycling operation.

Another object of the present invention is to provide an automatic sorting press for iron cans, aluminum cans and plastic bottles, which is small in volume and does not take up much space. In addition, the compactor is easy and convenient to operate.

It is yet another object of the present invention to provide an automatic sorting press for iron cans, aluminum cans and plastic bottles with a minimum of failures to ensure user safety as well.

Through the following description and the annexed drawings, it will be apparent that the foregoing and other objects of the present invention are achieved.

First, referring to FIGS. 1 to 4, an inlet 11 is provided at an upper end of the main body 1 of the present invention. At a predetermined position of the inlet 11, one or more sensing switches 12 are arranged. Under the inlet 11, a receptor 13 is arranged. The one-way outlet 14 and the two-way outlet 15 are fitted to the front end and the rear end of the container 13. At the two-way outlet 15, an outlet selector 17 controlled by a magnetic switching valve 16 is arranged. Beneath each of the three channels of the outlets 14, 15 are vessels 18a, 18b, 18c. The pressure shaft 21 of the spindle 2 passes through the receiver 13. The electromagnet 22 and the electrode 23a are fitted to the front end of the pressure shaft 21, and the other electrode 23b opposite to the said electrode 23a is provided in the predetermined position of the main body 1. As shown in FIG. The micro switch 24 is disposed at the position where the pressure shaft 21 retreats farthest. The sense switch 12 and the micro switch 24 are used to start or end the operation of the spindle 2.

Based on the foregoing, when the can is fed to the device of the present invention through the inlet 11, the can can touch the sensing switch 12 and enter the receiver 13. The operating signal of the sense switch 12 can actuate the spindle 2 such that the pressure axis 21 is moved forward. While the can is pressed, electrodes 23a and 23b will check if the pressed can is electrically conductive. If it is not electrically conductive it will be considered a plastic bottle. In addition, the magnetic switching valve 16 will not operate and the outlet selector 17 is tilted to the left so that the squeezed plastic bottle enters the right container 18c as shown in FIGS. 1 and 2. There will be. If electrically conductive, the compressed can is a metal (iron or aluminum) can. In this case, the magnetic switching valve 16 is operated so that the outlet selector 17 can be tilted to the right. Thus, the exit direction of the two-way outlet 15 is changed. At the same time, the compressed cans will be checked by the electromagnet 22 to have magnetic attraction. Iron cans have magnetic attraction, while aluminum cans have no magnetic attraction. If the compressed can is an aluminum can, it will go directly into the intermediate container 18b. And if the pressed can is an iron can, the electromagnet 22 will pull it towards the front end of the receiver 13. When the pressure shaft 21 touches the micro switch 24, the spindle 2 stops operating. Therefore, the electromagnet 22 does not have a magnetic attraction so that the iron can automatically enters the left container 18a. Therefore, the automatic sorting and pressing operation is completed as shown in the flowchart shown in FIG.

In addition, both electrodes 23a and 23b use only direct current whose voltage reaches about 6V. Thus, there is no risk. In order to ensure safety in using the present invention, an insulator 231 is fitted to the inner side surfaces of the electrodes 23a and 23b. Thus, the main body 1 of the present invention is insulated, and leakage of electricity is reduced to a minimum.

Further, the reciprocating motion of the pressure shaft 21 of the commercially available spindle 2 can of course also be adjusted in advance. However, the volume of the can being recycled is different. If the movement of the pressure shaft 21 is fixed, the pressure shaft 21 is easily broken, since the pressure shaft 21 may be overloaded when pressing a larger or hard can. Therefore, the motor 20 which drives the pressure shaft 21 is connected with the current-controlled device 201. This current controlled device 201 may be a conventional ammeter. If a certain amount of current is applied to the motor 20, this means that the pressure shaft 21 squeezes the empty can such that a larger counter force or an obstacle is encountered so that the pressure shaft 21 can no longer move. . In this case, in order to prevent the failure of the spindle 2, the motor 20 is operated in reverse to return to the original state.

Therefore, the present invention can squeeze and automatically sort conventional cans (iron cans, aluminum cans and plastic bottles, etc.). Thus, the sorting operation and the storage space can be significantly reduced, thereby achieving a recycling effect. In order to enhance safety in use, as shown in FIG. 5, the inlet 11 is provided with a protective cover 19. In addition, the spindle 2 can only be operated when the protective cover 19 is closed.

In the embodiment shown in FIGS. 1 to 5 the motor 20 of the spindle 2 consists of a vertical motor. In addition, the inlet 11 slightly protrudes above the main body 1. This arrangement has unique advantages and meets the needs of some companies. However, a typical shop requires a small presser with a faster pressing speed. In order to improve speed without reducing the torque of the motor, the horsepower of the motor must be increased so that volume will increase. In order to eliminate the above disadvantages, as illustrated in FIGS. 6 to 8, a more efficient motor 20 of another embodiment of the present invention is installed in the body 1 in the horizontal direction. Thus, the total height, combined with the height H1 of the main body 1 reaching only 25 cm and the height H2 of the support legs, will not exceed 50 cm. The width W reaches about 45 cm and the length reaches about 100 cm. The automatic classifying presses of the above mentioned dimensions are suitable for use in general shops. The features of this embodiment are almost the same as the features of the previous embodiment and will not be described further below. The only difference is that the inlet 11 does not protrude above the body 1, and that a lid 3 is provided which can be opened and closed laterally to open and close the inlet 11. This cover 3 is made of transparent PVC and has a handle 31. In addition, the micro switch 32 is provided in the position corresponding to the closed position of the lid 3, and is operated by contact with the lid 3. When the empty can P enters the inlet 11, it touches the sensing switch 12. After the lid 3 is closed and touches the micro switch 32, the spindle 2 starts moving forward to perform sorting and pressing operations. On the other hand, the operation can be observed through the transparent cover (3). If a person opens the cover 3, the micro switch 32 is released to stop the operation of the spindle 2 to ensure safety in use. Thus, this kind of compactor is more suitable for use in public places.

Of course, many variations and modifications of the foregoing embodiments of the present invention may be made without departing from the scope of the present invention. Thus, to encourage the development of academic and practical sciences, the present invention is disclosed and limited only to the scope of the appended claims.

According to the device of the present invention, plastic bottles are sorted by electric conductivity, and iron cans and aluminum cans are sorted by magnetic attraction and pressed together, so that the three most common containers can be sorted at the same time, and their storage space is also significantly reduced. In addition, the recycling operation is easy, and also the compactor of the present invention is easy and convenient to operate and the failure is reduced to a minimum, thereby ensuring the safety of the user.
