  The present invention relates to a waste separation apparatus that can separate and extract label fragments, bag debris, and the like mixed in a crushed plastic bottle.

  The used PET bottle is finely pulverized by, for example, a PET bottle collecting apparatus described in Patent Document 1, and then reused for various recycled products as an egg pack sheet or polyester fiber. The PET bottle collection device described in Patent Document 1 includes a rotary cutter that cuts a PET bottle, a label peeling mechanism that peels off the label of the cut PET bottle, and a crushing mechanism that further cuts the cut PET bottle. PET bottle collection device.

  A PET bottle cut by such a collecting device is usually in a state where a peeled label or the like is mixed in a fragment of a crushed PET bottle. Therefore, next, the process of removing these labels etc. using a sorter etc. is needed. At this time, the crushed PET bottle fragments are packed and transported in the bag while being mixed with the label and the like, and the bag is transported together with the sorter. In such a sorting process, it is necessary to remove not only the labels mixed in the cut PET bottles but also the debris of the bag body in which these are stored. For this reason, conventionally, bag residue and separated labels are separated using a bag removal machine for sorting.

  Patent Document 2 describes a bag removal machine that sorts and removes bag debris and the like. This bag removal machine is provided with a negative pressure chamber and a positive pressure chamber using an air discharge port and an air supply port by a blower in the inside of a perforated rotating cylinder that conveys the bag residue.

  Embodiments of the present invention will be described below. The basic configuration of the present invention includes a hopper 10, a blower duct 20, a discharge duct 30, and a storage tool 40.

  The hopper 10 is a bag containing a plastic bottle fragment P which is torn together with a bag debris R after being broken by a bag breaker (not shown). Are put in a mixed state with the broken pieces Q and the bag debris R (see FIG. 1). This hopper 10 is installed directly under the bag breaker. Moreover, you may comprise so that the bag body P and waste Q which were discharged | emitted from the bag breaker may be conveyed with a belt conveyor (not shown), and may be thrown into the hopper 10. FIG. While the plastic bottle fragments P, the label fragments Q, the bag debris R, etc., which have been put into the hopper 10 are discharged from the hopper 10 through the discharge pipe 11 disposed obliquely below, Fragments Q and bag debris R are blown away by a blower, and only plastic bottle fragments P are selected.

  A rotary blade 70 can be installed inside or above the hopper 10 (see FIG. 1). The rotating blade 70 is for tearing an unopened bag by rotating. That is, there are cases where small bags containing plastic bottle fragments P and label fragments Q are collected and transported in a large plastic bag. In this case, a large plastic bag may be torn by a bag breaking machine, but not all small bags may be torn. In such a case, the sachet is cut using the rotary blade 70 to discharge the plastic bottle fragment P or the label fragment Q, or to separate the plastic bag or the like that has digged into the plastic bottle fragment P. It is. In the illustrated example, the rotary blade 70 is disposed above the square U-bolt 10, but the installation position of the rotary blade 70 and the presence or absence of the installation can be freely selected.

  The blower duct 20 blows out the blower sent from the blower 21 from the lower side to the upper side of the hopper 10, and blows up the broken pieces Q of the label and the bag debris R which are put into the hopper 10, so that the broken pieces of the plastic bottle. It is a member separated from P (see FIG. 1). An air volume adjusting plate 50 can be detachably attached to the air outlet 22 of the air duct 20 as necessary. The illustrated outlet 22 opens into the discharge pipe 11 below the hopper 10.

Furthermore, it is also possible to provide a wall surrounding the discharge duct 30 with a space therebetween, and the clearance between the wall and the front end can be used as the exhaust port 31. Thus, the shape and mode of the exhaust port 31 can be arbitrarily changed.

  Furthermore, in the example of illustration, the auxiliary ventilation duct 60 is installed in the middle of the discharge duct 30 (refer FIG. 2). The auxiliary air duct 60 blows out the blower that blows up the label fragments Q and the bag debris R blown up by the blower from the air duct 20, and removes the label debris Q and the bag debris R. The discharge duct 30 is configured so as to be reliably sent out in the direction of the distal end. Further, by providing the air outlet 61 of the auxiliary air duct 60 so as to be freely opened and closed, the air volume of the blower blown from the auxiliary air duct 60 can be adjusted (see FIG. 6). The air outlet 61 shown in the figure forms a bifurcated air outlet 61, and is provided with an air volume adjusting valve 62 that swings on the base end side of the branched portion. Then, by operating the adjustment handle 63, the position of the air volume adjusting valve 62 is changed so that the air volume of the blower blown out from each outlet 61 can be freely adjusted. The blower to be sent to the auxiliary air duct 60 may use the blower 21 that sends the blower to the air duct 20, but it is also possible to use another blower (not shown). When the air volume from the air duct 20 is sufficient, the auxiliary air duct 60 may not be used.
