Description

  The present invention relates to a resource bottle recycling system and a resource bottle recycling method for color-sorting collected resource bottles.

  Conventionally, for example, resource bottles discharged from homes or the like are temporarily collected at a collection place, and then transported to a recycling facility, where processing such as color selection is performed and reused and reused. Such resource bottle collection methods vary depending on the local government (region) that operates the recycling facility. Bag collection methods that collect and collect resource bottles in bags, and container collection methods that collect and collect resource bottles in containers There is. And the receiving line (process) of a recycling facility also differs so as to correspond to these collection methods.

  In the bag collection method, the resource bottles stored in the bags are put into a packer car (collection vehicle) and transported to a recycling facility. At the receiving line of the recycling facility, the resource bottles collected in the bag are put into the receiving hopper, transported by the transport means, then the bag is broken by the bag breaker, and the color of the resource bottles is selected ( (See, for example, Patent Document 1).

On the other hand, in the container collection method, the resource bottles accommodated in the container are loaded on the loading platform of a truck or the like (collection vehicle) and transported to a recycling facility. At the receiving line of the recycling facility, the resource bottles collected in the container are temporarily stored in the receiving yard, transported by the transport means, and then reversed by an automatic reversing device that reverses the container, so that the color sorting of the resource bottles is performed. It is introduced into a processing line (process) to be performed.

  In recent years, due to the merger of local governments and the widening of waste disposal areas, there are an increasing number of cases where regional resource bottles that have adopted different collection methods are processed at one recycling facility. In such cases, the resource bottle collection method was unified.

  For example, in the case of unifying the bag collection method, it is necessary to newly prepare a packer car as a collection vehicle, a receiving hopper as a receiving facility of a recycling facility, a bag breaking machine, and the like. In addition, in the bag collection method, when a resource bottle is put into a packer car or a receiving hopper, a part of the resource bottle is damaged, and the recycling rate / regeneration purity of the resource bottle deteriorates and the recycling rate decreases. When there is a problem and the bag collection method is unified, the recycling rate of resource bottles corresponding to the change from the container collection method to the bag collection method is lowered, and the overall recycling rate is further lowered.

  On the other hand, in the case of unifying the container collection method, it is necessary to newly prepare a truck as a collection vehicle, an automatic reversing device as a receiving facility for a recycling facility, a container and the like. Further, in the container collection method, when a container unloads a container from a truck, a worker is required. When the container collection method is unified, it is necessary to increase the number of workers.

  Furthermore, regardless of which collection method is used, public relations activities are required to inform the residents in the area where the collection method will be changed in advance. There is a problem that it is necessary.

  In this way, when regions that adopt different resource bottle collection methods are merged, new costs are required, which has been a heavy burden on the local governments that operate recycling facilities.

  The present invention has been made to solve such problems, and provides a resource bottle recycling system and a resource bottle recycling method capable of reducing costs when merging regions that employ different resource bottle collection methods. The purpose is to do.

Stop the introduction of the resource bottle from the line to the processing line, temporarily store the container in the automatic warehouse, and temporarily store it in the automatic warehouse when the resource bottle is not introduced from the first receiving line to the processing line If the configuration is such that the resource bottle in the container is introduced into the processing line, the above-described operation is effectively achieved, the timing at which the resource bottle is introduced from the first receiving line to the processing line, and the second Resource bottles introduced from the first receiving line and resources introduced from the second receiving line because the timing of introducing the resource bottles from the receiving line to the processing line is different. There is no collision with you, damage to the resource bottle is prevented. Moreover, since the resource bottle accommodated in the container can be temporarily stored, the amount of the resource bottle introduced into the processing line can be adjusted.

  The second receiving step stops the introduction of the resource bottle from the second receiving step to the processing step when a predetermined amount of the resource bottle is introduced from the first receiving step to the processing step. Is stored temporarily in the automatic warehouse, and the resource bottle in the container temporarily stored in the automatic warehouse is introduced into the processing process when the resource bottle is not introduced from the first receiving process to the processing process. -When the introduction process is included, the above-described action is effectively achieved, the timing at which the resource bottle is introduced from the first acceptance process to the treatment process, and the resource bottle from the second acceptance process to the treatment process. Since the introduction timing is different, there is no collision between the resource bottle introduced from the first receiving process and the resource bottle introduced from the second receiving process, and damage to the resource bottle is prevented. Moreover, since the resource bottle accommodated in the container can be temporarily stored, the amount of the resource bottle introduced into the treatment process can be adjusted.
