Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collection bag capable of separating a collection bag and a recyclable collection product such as a bottle and a can at the same time as the collection bag is torn. The present invention relates to a bag breaking and bag removing apparatus. 2. Description of the Related Art As shown in FIG. 7, a conventional bag breaking device tears a collection bag by scraping both sides of the collection bag with a stopper and a bag-breaking blade, and recycles the collection bag and a bottle or can. Since the method is for separating possible collected items, the collected bags and the collected items are mixed. In order to recycle the collected items, it is necessary to remove the collected bags from the mixture of the collected bags and the collected items. There is a problem that the introduction cost of the machine is high. Further, even if the collection bag is cut off and the collected product is taken out of the collection bag, there is a problem that the collected product still remains in the collection bag. [0003] In view of such circumstances, the present invention is capable of tearing the collection bag and removing all the collected items from the collection bag. An object of the present invention is to provide an apparatus for removing a bag that can be mechanically separated. According to a first aspect of the present invention, there is provided an apparatus for removing a bag for breaking a collection bag, comprising: (A) an input port 2 for inputting a collection bag 1 containing collected items; In an apparatus having a bag-breaking conveyor 3 provided horizontally below the mouth 2 and a conveyor 4 provided below the bag-breaking conveyor 3, (B) the bag-breaking conveyor 3 has a plurality of bag-breakers on its flat surface. A blade is attached, and (C) a discharge roller 5 for stopping and discharging the collection bag is provided in the vicinity of the outlet side above the bag breaking conveyor 3 so as to face the bag breaking conveyor 3, and (D)
A nozzle 6 for blowing air toward the discharge roller 5 is provided below the discharge roller 5, and (E) a suction discharge roller 7 for sucking and discharging the collection bag on the side of the outlet side of the bag breaking conveyor 3. (F) A nozzle 8 for blowing air toward the suction / discharge roller is provided beside the suction / discharge roller 7 (G). [0005] In this specification, the term "collected product" refers to a recyclable product such as a bottle, a steel can, an aluminum can, and a plastic bottle. In this specification, the "discharge roller 5" is provided with a plurality of ventilation grooves as shown in FIG. In the present specification, as shown in FIG. 6, the inside of the cylinder of the "suction and discharge roller 7" is partitioned by a plate (the partition plate is fixed and non-rotating, and only the cylinder is rotated by power). Is sucked in by a blower, and the opposite side (discharge side) is blown by a blower. Since the present invention has the above-mentioned structure, the collected bag 1 is conveyed by the bag-breaking conveyor 3 and rolled into the discharge roller 5 when it comes into contact with the discharge roller 5. After stopping, the bottom is torn by the bag-breaking blade 9 attached to the conveyor, the collected product is separated from the collected bag, and the collected bag is discharged. Even if there are collected items left in the collection bag,
The collection bag and the collection product are not mixed by being squeezed by the roller. When a small bag or the like remains, it is sucked by the suction and discharge roller 7 on the side and separated and discharged. Since a nozzle 6 for blowing air toward the discharge roller 5 is provided below the discharge roller 5, the collection bag 1 is pressed against the discharge roller 5 by wind pressure, and is caught in the discharge roller 5. Easy to be. Since the discharge roller 5 is provided with a plurality of ventilation grooves, the air blown from the nozzle 6
Blow through the groove. Therefore, the collection bag entrained by the discharge roller is blown off in the air direction, and the discharge roller 5
Break away from Since the air is sucked into the suction side of the suction / discharge roller 7, the small bag or the like that has not been caught by the discharge roller 5 is suctioned by suction force and is caught by the suction / discharge roller 7. Since the air supply side of the suction / discharge roller 7 discharges air, the collected bag that has been entrained is blown off.
It is separated from the suction / discharge roller 7. A nozzle 8 for blowing air toward the suction / discharge roller is provided on a side of the suction / discharge roller 7.
Since it is blown off to the suction / discharge roller 7 side, it is easily sucked by the suction / discharge roller 7. [0014] Therefore, the bag removal and the collection product can be separated at the same time, and furthermore, since the bag is rolled up by the roller, the bag removal and the collection product can be surely separated, and the present invention seems to be very effective. You.
