Description

  The present invention relates to a self-propelled vehicle having a waste recycling function, which is configured to be able to perform a recycling process up to a predetermined stage on a container waste collected while traveling.

  Conventionally, container waste such as used PET bottles is collected by a waste collection vehicle and once unloaded to an intermediate processing plant, where volume reduction processing such as compression processing and chip processing is executed. The container waste that has undergone this volume reduction treatment is transported from the intermediate treatment plant to the recycling plant as the final disposal site, where the container waste reduced in volume is subjected to final disposal for recycling. It is common.

  However, such a container waste recycling system has a disadvantage that enormous investment is required to construct an intermediate treatment plant. In order to eliminate such inconvenience, Patent Documents 1 to 3 propose that volume reduction processing is performed on a container waste collected by a waste collection vehicle that is a self-propelled vehicle.

  However, since the thing of patent document 1 is what only compresses a plastic bottle and volume-removes, it may be necessary to chip at a final factory, and is insufficient as intermediate processing of a container waste. There is a problem that there is.

  On the other hand, in Patent Documents 2 and 3, a plastic bottle can be cut by a cutting device provided at the end of the loading platform. However, there is a problem that the operator has to insert the PET bottles one by one into the cutting process one by one and perform the cutting process, resulting in poor workability.

  In order to solve such a conventional problem, the inventor of the present invention invented a self-propelled vehicle having a waste recycling function as previously described in Patent Document 4. The loading platform of the self-propelled vehicle is provided with an aligning section in which container wastes are aligned, and the aligned container wastes are sequentially subjected to chipping processing. Therefore, there is no need to perform the troublesome work of manually supplying the container waste collected by the worker one by one to the cutting device and converting it into chips as in the prior art. The work efficiency of the chip processing can be greatly improved, and as a result, it is possible to contribute to an efficient recycling process of container waste.

Japanese Patent Laid-Open No. 10-291603 Japanese Patent Laid-Open No. 10-249857 JP-A-10-250802 JP 2009-62172 A

  By the way, in the self-propelled vehicle described in Patent Document 4, when processing container waste into chips, first, the container waste is first subjected to compression treatment, and the flattened container waste is removed with a saw blade. A chipping process is performed on the fragment after the vertical segmentation.

  However, when the container waste is first compressed, the label wound around the surface of the container waste is more strongly pressed against the container body and is not easily peeled off. It has been found that there is a problem that the peeling action of the label is not performed well.

  Further, when the container waste is cut with a saw blade, it takes a lot of time, and there is a problem that an efficient cutting process cannot be performed.

  The present invention has been made in view of such a conventional situation, and is wound around the surface of a used bottle after ensuring the quick separation processing of the collected used plastic-made bottles. It is possible to provide a self-propelled vehicle having a waste recycling function that can reliably remove a label, and can reliably prevent the label from being mixed into a collected material that has been cut into chips. It is aimed.

The invention according to claim 1 is a self-propelled vehicle having a waste recycling function for disassembling a loaded synthetic resin used bottle to a predetermined stage, and aligning the used bottles that are sequentially inserted. And a chip storage unit that cuts the used bottles aligned in the alignment unit into chips, and a chip storage unit that stores chips manufactured in the chip processing unit, The chip processing unit divides the used bottles arranged in the alignment unit and separates them into bottle bodies and accessories to be collected, and cuts the collection objects sorted by the sorting unit. A cutting section for processing into chips, and an accessory storage section for storing the accessories sorted by the sorting section, wherein the sorting section has a cap as an accessory to the bottle body. Attached A cutting device for longitudinal at least two along the longitudinal direction of the used bottle including its cap in the state, appendage recovery for recovering the adjunct used bottles are separated upon being divided by the dividing device A self-propelled vehicle having a waste recycling function, comprising: a section; and a compression device that compresses the collection object obtained by being divided by the dividing device.

  According to such a configuration, the used bottles made of synthetic resin loaded on the platform of the self-propelled vehicle are first aligned so as to be easily processed by the alignment unit, and then subjected to compression processing by the dividing device of the separation unit. It is divided into at least two before being rubbed. The object to be collected obtained by the division is compressed by the compression device of the separation unit, then cut by the cutting unit to form a chip, and stored in the chip storage unit.

  On the other hand, an accessory such as a label that has been cut when the used bottle is cut by the cutting device is removed from the collection target that is the main body of the bottle and is collected by the accessory collection unit.

  And since the used bottle is first divided into at least two when it is in a state where it is easy to separate accessories such as labels and caps before being compressed, if the compression process is performed first, It is possible to effectively prevent the occurrence of problems such that attachments such as labels and labels stick firmly to the collection object and are difficult to separate, and the attachments can be easily removed from the used bottle.

According to a second aspect of the present invention, in the first aspect of the present invention, the cutting device includes a press cutting machine for cutting the used bottle by press processing, and the compression device compresses the bottle body. A compression roller device having a compression roller, and a lattice that is used as a pedestal for the compression roller when the bottle body is compressed by the compression roller, and that sifts the bottle body as a sieved product and the cap as a sieved product. And a sieving device having a body . According to such a configuration, since the used bottle is divided very quickly by the press cutting machine, there is an inconvenience that the cutting process becomes a bottleneck and the processing efficiency of the chip forming process for the used bottle is lowered. Does not occur.

According to a third aspect of the present invention, in the second aspect of the present invention, a vibration mechanism that provides vibration to the lattice body is provided.

  According to this configuration, when the used bottle is being subjected to the separation process, the used bottle is also vibrated by driving the vibration mechanism to vibrate a part of the separation unit. Thus, accessories such as caps and labels that have been cut can be easily separated from the used bottle.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the accessory collection unit includes a suction device that sucks and removes the labels wound around the used bottle. It is characterized by being.

  According to this configuration, when the labels are wound around the bottle, the labels are also cut and separated from the bottle by the bottle dividing process. Then, the labels that are easily separated are attracted to the airflow by the suction device and peeled off to be removed by suction. In this way, by providing a suction device so that the labels can be sucked, even if the labels are wrapped around the bottle body, the labels are removed from the bottle body side. It is possible to effectively prevent the occurrence of inconvenience such as mixing different labels.

  According to the self-propelled vehicle having a waste recycling function according to the present invention, the collected used plastic resin bottles are aligned and arranged in series by being sequentially inserted into the alignment unit, and are formed into chips in this state. Since it is sent to the processing unit and cut into chips, it is troublesome to manually supply the container waste collected by the operator one by one to the cutting device one by one as before. As a result, it is possible to greatly improve the workability of the chip processing of the container waste using the self-propelled vehicle, and to achieve the efficiency of the chip processing.

  In such a used bottle chipping process, the used bottle is subjected to a cutting process in a state in which the accessories such as the label and the cap are easily separated prior to the compression process. It is possible to effectively prevent the occurrence of a problem such that the sticking firmly adheres to the object to be collected and is difficult to separate, and the accessories can be more effectively removed from the used bottle.

  As described in detail above, the factory truck 10 according to the above-described embodiment is a waste that is decomposed until the plastic bottle P is made into a chip P3 while collecting the plastic bottle P made of PET that is a material that can be recycled and used. The present invention relates to a factory truck 10 as a self-propelled vehicle having a regeneration function. The alignment unit 30 aligns the plastic bottles P sequentially fed through the input unit 20, and the plastic bottle P aligned by the alignment unit 30 is cut. The loading platform 12 is equipped with a chip processing unit 40 that converts the chips into chips and a chip storage unit 80 that stores the chips manufactured by the chip processing units 40.

  According to such a configuration, the collected PET bottles P are aligned and arranged in series by being sequentially inserted into the aligning unit 30, thereby enabling subsequent processing to be sent to the chip processing unit 40. Here, it is cut into chips. Then, the obtained chip is stored in the chip storage unit 80.

  In this way, the loading platform 12 of the self-propelled vehicle is provided with the alignment unit 30 in which the plastic bottles P are aligned, and the aligned plastic bottles P are sequentially subjected to chipping processing. There is no need to perform the troublesome work of manually supplying the PET bottles P collected by the operator one by one to the cutting device one by one and making them into chips, as a result, and as a result, the PET bottles P using the self-propelled vehicle Thus, the workability of the chip conversion process can be greatly improved, and the efficiency of the chip conversion process of the plastic bottle P can be greatly increased.

  Particularly in this embodiment, the PET bottle P is subjected to the dividing process in the dividing apparatus 51 when it is easy to separate the accessory P2 such as a label or a cap before the compression apparatus 56 performs the compression process. Therefore, when the compression process is performed first, it is possible to effectively prevent the occurrence of problems such as attachments such as caps and labels firmly sticking to the object to be collected and difficult to separate. Therefore, it is possible to achieve an exceptional effect that the accessory P2 such as a label can be effectively removed.

  Further, since the sieving device 58 is provided with a vibration mechanism 583 that vibrates the frame body 581, the vibration mechanism 583 is driven to vibrate the frame body 581, thereby causing the plastic bottle P to vibrate simultaneously. It is possible to easily separate the accessory P2 such as a cap or a label that is cut by the vibration from the bottle main body P1.

  In addition, the sieving device 58 is configured to collect the bottle body P1 as the top of the sieve while collecting the cap or the like as the bottom of the sieving. By supplying to the apparatus, the two-divided PET bottle P obtained by the dividing process is collected as a sieve, while an accessory P2 such as a cap or a cap having a small capacity is sieved as a sieve. . Thus, by adopting the sieving device 58 as the separation device, the bottle body P1 and the accessory P2 can be reliably separated from each other with the separation device having a simple structure.

  Furthermore, since it has the suction device 70 which sucks and removes the labels wound around the PET bottle P as an accessory collection unit, the labels cut simultaneously by the separation processing of the PET bottle P are performed by the suction device 70. It is attracted by the air current and peeled off, and sucked by the suction device 70 and removed. Therefore, it is possible to effectively prevent the occurrence of inconveniences such as labels mixed into the chip P3.

  The present invention is not limited to the above embodiment, and includes the following contents.

  (1) In the above-described embodiment, the PET bottle P is once inserted into the input unit 20 of the factory truck 10. However, the PET bottle P is directly supplied to the alignment unit 30 without providing the input unit 20. You may make it throw in.

  (2) In the factory truck 10 of the above-described embodiment, the PET bottle P is sent one by one from the alignment unit 30 to the downstream cutting device 51 to perform the cutting process. A plurality of members 52 may be provided, and a plurality of plastic bottles P that have entered each collar member 52 may be simultaneously subjected to a breaking process.

  (3) In the above-described embodiment, the plastic bottle P is described as an example of the container waste to be chipped. However, the present invention is limited to the container waste being the plastic bottle P. However, the object to be chipped may be other types of synthetic resin container waste.

  (4) In the above embodiment, the press cutting machine 54 including the cutting blade 541 that moves up and down as a member for cutting the plastic bottle P is employed. However, the present invention is not limited to the use of the press cutting machine 54, and the pet bottle P is cut by a reciprocating path of a saw blade or by pressing the plastic bottle P against a rotating disk-shaped cutter. Various types of cutting machines such as cutting the bottle P may be adopted.

  (5) In order to efficiently execute the chip disposal process of the container waste using the factory truck 10 of the above embodiment, the chip P3 is stored in the factory truck 10 as shown in FIG. It is preferable to accompany a specialized shuttle truck 15. The reason is that the capacity of the chip storage unit 80 of the factory truck 10 cannot be increased so much that it is very inefficient to return the factory truck 10 to the recycling factory F every time the chip storage unit 80 is full. Because.

  Therefore, when the shuttle truck 15 is caused to accompany the factory truck 10, the chip P 3 is taken out from the chip storage section 80 of the factory truck 10 on the spot every time the chip storage section 80 of the factory truck 10 is full, and the loading platform of the shuttle truck 15. Therefore, the factory truck 10 does not need to return to the recycling factory F one by one, and the chip processing efficiency of the factory truck 10 can be improved accordingly.

  And the shuttle truck 15 should just convey the said chip | tip P3 to the recycle factory F when it becomes full with the chip | tip P3. That is, the shuttle truck 15 reciprocates between the factory truck 10 and the recycling factory F every time the loading platform is filled with the chips P3.
