Description

PET bottle recycling chip production automation machine

The present invention relates to a PET bottle recycling chip production automation machine, and more particularly, a process for crushing and packaging chips from a single PET bottle to a size that can be recycled by organically connecting the devices that need to go through recycling the PET bottle. The present invention relates to a PET bottle recycling chip production automation machine that is fully automated to enable PET bottle recycling business to be economical.

In general, PET bottles are light and have good moldability, so large beverage containers mostly use PET bottles.

PET bottles are not easily rotted, so if they are thrown away, the environment may be contaminated.In addition, since PET bottles are expensive synthetic resins, they may be economically wasteful if they are thrown away, so they are collected and recycled to make PET bottles or other products. It is even made by reducing it with a catalyst.

In order to recycle PET bottles, various processes must be followed. In other words, the materials attached to the PET bottle must be separated from each other and finely pulverized to improve regeneration efficiency.

Many different devices have been developed to do this. For example, there are various types of devices such as utility model registration number 92857, 98493 lamp label remover, and lower lid remover developed and filed by the present inventor.

However, since these devices replace some of the various processes to be regenerated, and these devices cannot be organically linked with each other, most of the work has to be done by hand. For this reason, a lot of labor costs were incurred, and productivity fell, so the PET bottle recycling business was not economically activated.

The present invention has been devised to solve such a conventional problem, and its object is to fully automate the process of crushing and packing chips of recyclable size in one PET bottle by organically connecting the devices that need to go through recycling PET bottles. Therefore, to provide PET bottle recycling chip production automation machine to activate PET bottle recycling business into economical business.

By this operation, the jaw 240 installed at the tip of the rotary shaft 237 is rotated so that the three pinned feet 242 are brought into close proximity to the bottle cap in a state opened by the centrifugal force.

The second cylinder 244, which was advanced together with the movable plate 234, was operated in a subsequent operation so that the operating plate and the jaw operating ring 247 connected to the rod were advanced to retract the foot 242 opened by centrifugal force. The first cylinder 232 is retracted at the same time as holding the lid. By this operation, the bottle cap is rotated along the jaws 240 to be separated from the bottleneck upon retreat. When the bottle cap is separated from the bottleneck, the second cylinder 244 retreats to push the foot 242, and the jaw operation ring 247 retreats and the foot 242 is freed, so the foot 242 is driven by centrifugal force in all directions. The bottle cap that was opened is dropped and removed.

When the bottle cap is removed, the clamp device 22 which grasps the bottleneck and fixes it returns to its original state. That is, the clamp cylinder 221 retracts and the links 224a and 224b connected to the rod 222 retreat, and the second and first arms 225a, 225b, 226a and 226b connected thereto are connected. ) Is opened in sequence, and the segments 227a and 227b that were holding the PET bottle are opened to free the PET bottle.

When this operation is completed, the stopped conveying device is operated again and the bottle cap is removed by operating the continuously supplied PET bottles in the same manner as the first time. Such a series of operations will automatically remove the bottle cap of each PET bottle that is repeatedly transported.

The label and the base cup which are removed and lowered are separated from the PET bottle and dropped downward by their own weight, and the lighter weight label is sucked and transported by a vacuum pump not shown in the drawing, and the base cup is also collected separately.

When the label and the base cup are removed and the fixing plates 423a and 423b reach the bottom end, another position detecting sensor 416b installed at the bottom thereof detects the first and second cylinders. 420a) and 420b operate to raise the rods 421a and 421b so that the tip of the scraper 442 of the scraper device 440 is positioned to the upper portion of the PET bottle, and at the same time, the third and fourth cylinders 425a and 425b. Return the protruding rods to their original position.

Then, the drive motor is operated and the attachment chain 35 is rotated again to transfer the PET bottle to the next process. When the PET bottle subsequently supplied is detected by the position detecting sensor 416a again, the operation as described above is repeated. This will automatically remove the label and base cup from the bottle.

In addition, while the label, the base cup is dropped by the scraper device to the bottom, the label is separated and stored by a separate vacuum adsorption apparatus not shown in the figure, the base cup is dropped by its own weight and stored in a separate collection box.

The label and bottle cap remover 40 is followed by the colored bottle separation chute 50 and the bottleneck remover 60.

These devices must pass through the bottles because each color is given according to the contents inside.

In particular, the material of the spout of the bottle is made of ordinary plastic, not PET, depending on the type of bottle. Therefore, these PET bottles can be separated by a sensor and cut and removed with a cutter to improve regeneration efficiency. For this reason, the colored bottle separation suit 24 separates the PET bottles for each color, and then removes the bottleneck through the bottleneck remover 60. At this time, the colored bottle is remembered by the sensor installed in the colored bottle separation chute 50, the bottleneck is cut by the bottleneck remover 60, and then separated into a separate colored bottle storage container (not shown) and then the transparent PET bottle After the operation is completed, the crusher 30 is supplied and crushed.

Colored bottle separation chute 50 is installed in the conveying conveyor 510 for transporting the PET bottle as shown in FIG.

The conveying conveyor 510 is a belt conveyor having guide plates 511 on both sides thereof so that the PET bottles do not fall during transportation, and discharge plates for discharging PET bottles other than the desired color to the ends of the guide plates 511 to the outside ( 520 is installed.

The discharge plate 520 is hingedly coupled to the guide plate 511 and is rotatably installed laterally. One side of the discharge plate 520 is provided with a cylinder 522 that is operated by air in a fixed frame, and the rod 523 of the cylinder 522 is connected to the connection bar 521 provided on the upper side of the discharge plate 520. It is connected. The cylinder 522 connected to the connecting bar 521 is installed to be rotated horizontally in anticipation of changing the direction of the connected point in a curved direction during the rotation operation of the discharge plate 520.

In addition, three long holes are formed in the guide plate 511 adjacent to the discharge plate 520 to install the sensors 512a and 512b. The sensors 512a and 512b are optical sensors and include a light emitting part for transmitting light in the long hole of the guide plate 511 and a light receiving part for receiving light emitted in the long hole of the other guide plate 511.

When the PET bottle is transported through the conveying conveyor 510 and passed through the colored bottle sorting sensors 512a and 512b by this structure, the light emitted from the light emitting part passes through the PET bottle to receive the intensity of the light received by the light receiving part. The color is discriminated by discrimination.

If the transparent PET bottle is set to be recycled, the transparent bottle is passed as it is, and when the colored PET bottle passes, the cylinder 522 is operated by the rod 523 when the PET bottle is placed at the discharge plate 520. The discharge plate 520 is pushed while protruding. By this operation, the discharge plate 520 is rotated, and the PET bottle located therein is continuously transported by the operation of the transfer conveyor 510 and eventually discharged to the outside. When the discharge of the PET bottle is completed, the cylinder 522 retracts the rod 523 and returns the discharge plate 520 to be parallel with the guide plate 511.

In addition, a second storage hopper 70 is installed at one side of the bottleneck cutter 60 and is connected to each other through a transfer conveyor 627. The second storage hopper 70 stores the bottle from which the bottleneck is removed by the conveying conveyor, and has a capacity to store a PET bottle of about 15 minutes of work for smooth operation.

The crusher 80 is installed at the next position of the second storage hopper 70. At the inlet of this crusher 80, two rollers 832 with wings are engaged with each other, and a crushing blade 833 is provided at the lower portion thereof. The roller 832 is forcibly injected downward through the wing while pressing the PET bottle, the wing is to crush the injected PET bottle. However, since the volume of the PET bottle is large, when the shredding blade 833 crushes the PET bottle, a phenomenon in which the PET bottle is bounced upwards and rises, and the crushing efficiency decreases. At this time, the roller bottle 832 is bounced up to block the PET bottle, and the bottle is forced to be injected by pressing the PET bottle, so the PET bottle can only be injected into the shredding blade 833, thereby increasing the crushing efficiency. The crusher 80 crushes the PET bottle to about 10 mm and stores it in the hopper configured at the bottom.

One side of the crusher 80 is provided with a spring feeder 34. The spring feeder 90 has a coil-shaped spring inside the tube, and the spring is rotated by an upper motor. One end of the spring feeder 90 is connected to the inside of the hopper installed at the bottom of the crusher 80. The other side is located towards the packaging platform.

Therefore, the PET bottle crushed in a small chip state is transported by the coil spring rotated in the inside of the tube to be packaged in the packaging 92.

The order of the devices described above can be changed as needed. In particular, the ring removing device may be disposed in the entire process of the bottleneck cutter 26.

As described above, the present invention has an effect that the process of crushing and packaging the chips into sizes that can be recycled in a single PET bottle is organically connected to each other so as to perform a series of processes. .

In addition, the PET bottle regeneration operation is rapidly performed by this consistent and rapid process, thereby doubling the PET bottle regeneration capacity and thus increasing productivity. In addition, as the lid, label, and base cup made of different materials are reliably separated and collected, the regeneration efficiency is also greatly improved. Moreover, it is a beneficial system that can be recycled 100% by using them as recyclable materials.
