Based on the height position information of the diameter inspection sensor 31, the exclusion member 32 pushes out the coffee can container from the side of the first conveyance path 21 to the outside of the first conveyance path 21 and eliminates it.

  When the PET bottle 100 is sent to the orientation adjustment unit 4, based on the inspection information of the orientation inspection sensor 41, the orientation adjustment unit 4 determines whether the mouth portion 101 b (cap 103) of the PET bottle 100 is located on the front side. Determine whether or not.

  Further, the plastic bottle 100 is held so as to be held between the holding members 42a. When the orientation adjustment unit 4 determines that the mouth portion 101b (cap 103) of the plastic bottle 100 is positioned on the front side, the orientation adjustment unit 4 moves the holding member 42a counterclockwise (W direction in the drawing) as shown in FIG. ), And the orientation is adjusted so that the mouth portion 101 b (cap 103) of the PET bottle 100 is on the front side of the second conveyance path 22.

  On the other hand, if it is determined that the mouth portion 101b (cap 103) of the plastic bottle 100 is not located on the front side, the holding member 42a is rotated 90 ° clockwise (Z direction in the figure) to The orientation is adjusted so that the mouth portion 101b (cap 103) is on the front side of the second conveyance path 22.

  The direction-adjusted PET bottle 100 is transported by the second transport member 23 to the cap removing portion 5 on the start end side of the second transport path 22, and the cap 103 is disposed between the two operation pieces 52 a of the dismount operation member 52. Is done. In addition, the 2nd conveyance member 23 returns to the original position after conveying the PET bottle 100 to the cap removal part 5, and conveys the next PET bottle 100 to the cap removal part 5. FIG.

  The plastic bottle 100 transported to the cap removing portion 5 is gripped by the chuck member 51 from both the left and right sides of the plastic bottle 100, and the second movable operation member 52h is operated, so that the two operation pieces 52a of the removal operation member 52 are operated. Move inward in the radial direction of the body 101a so as to approach each other. Accordingly, the lower end of the contact portion 52b of the operation piece 52a on one side (the left side in FIG. 6) and the upper end portion of the contact portion 52b of the operation piece 52a on the other side (the right side in FIG. 6) Each come into contact with the cap 103.

  From this state, each first movable operation member 52c operates, and as shown in FIG. 7, the operation piece 52a on one side (the left side in FIG. 7) moves downward, and the other side (the one on the right side in FIG. 7). ) Operation piece 52a moves upward.

  When the operation pieces 52a are moved, the cap 103 is rotated with respect to the PET bottle main body 101 in the counterclockwise direction of FIG. 7, and at that time, the contact portion 52b of the operation piece 52a is formed in an uneven shape. Therefore, the cap 103 and the contact portion 52b are difficult to slip, and the cap 103 rotates with respect to the PET bottle body 101 efficiently and reliably, and the cap 103 is detached from the PET bottle body 101.

  After the cap 103 is removed from the plastic bottle main body 101, the chuck member 51 and the removal operation member 52 are returned to their original positions. The removed cap 103 is stored and collected in a cap storage portion (not shown) provided below the cap removal portion 5 in the apparatus main body 10.

  The PET bottle 100 from which the cap 103 has been removed passes through the label peeling unit 5 by the third transport member 24. During the passage, the label peeling unit 5 operates with respect to the plastic bottle 100 as follows.

  First, when the PET bottle 100 is transported to the position of the label cutting member 61, the blade portion 61a of the label cutting member 61 comes into contact with the trunk portion 101a of the PET bottle 100 and is pressed forward as shown in FIG. . With the pressing, the label cutting member 61 resists the urging force of the urging member 62 and the blade portion 61a rotates forward with the connecting portion 61c as a rotation shaft (indicated by a two-dot chain line in FIG. 9). State shown).

  And the PET bottle 100 passes the blade part 61a by the 3rd conveyance member 24 (refer FIG. 8) in the state which the blade part 61a of the label cutting member 61 contact | abutted to the trunk | drum 101a. At that time, the blade portion 61 a is urged rearward by the urging force of the urging member 62, and the blade portion 61 a is pressed against the body portion 101 a of the plastic bottle 100.

  Therefore, when the plastic bottle 100 passes through the blade portion 61a, the label 102 of the plastic bottle 100 is cut into the blade portion 61a. The cut label 102 often sticks to the body 101a of the plastic bottle body 101 due to static electricity or the like.

  By cutting in this way, the blade portion 61a can cut only the label 102 without cutting the body portion 101a of the plastic bottle main body 101, so that no great force is applied to the blade portion 61a.

  Thereafter, the plastic bottle 100 passes through the heating member 63. When passing through the heating member 63, hot air is blown by the heating member 63 on the cut portion of the cut label 102. As a result, for example, as shown in FIG. 11, the cut portion of the label 102 is heat-shrinked and becomes a wave shape, and is lifted from the body portion 101 a of the PET bottle main body 101.

  Moreover, after passing through the heating member 63, the PET bottle 100 passes through the rotating brush members 64a to 64d. Then, during the passage, the label 102 is peeled off from the plastic bottle main body 101 by the brush bristles 64f.

  At that time, since the cut portion of the label 102 has a wave shape and is lifted from the body portion 101a of the plastic bottle main body 101, the brush bristles 64f are easily applied to the label 102, and are easily and reliably scraped off. Moreover, since the brush bristles 64f are made of synthetic resin such as nylon, the brush bristles 64f can be easily applied to the label 102, and can be more easily and reliably scraped off.

  Furthermore, when the PET bottle 100 passes through the rotating brush members 64a to 64d, the PET bottle 100 passes while being rotated by the first bottle guide member 65a, so that the label 102 is scraped off by the brush bristles 64f. Thereby, the label 102 is peeled off from the plastic bottle main body 101 when passing through the label peeling portion 5.

  The PET bottle body 101 from which the label 102 has been peeled is transported by the fourth transport member 25 from the label stripping section 5 until it passes through the dividing section 7.

  And when the plastic bottle main body 101 passes the dividing part 7, it is divided into two by the dividing tooth 72 at an axial direction.

  Specifically, when the PET bottle main body 101 is sent to the dividing portion 7, the first moving operation member 73 is operated, and the holding portion 71a holds the mouth portion 101b including the cap remaining ring 103a of the PET bottle main body 101.

  Thereafter, the second movement operation member 74 is operated, and the nipping piece 71 a is moved along the conveyance direction of the second conveyance path 22 along with the conveyance by the fourth conveyance member 25 of the plastic bottle body 101.

  And when the PET bottle main body 101 passes the parting teeth 72, it is divided into two in the axial direction. At this time, since the cap remaining ring 103a is sandwiched by the sandwiching piece 71a, the cap remaining ring 103a is cut into approximately equal two parts, and the cap remaining ring 103a is detached from the PET bottle main body 101.

  The cap remaining ring 103a is removed, and the plastic bottle main body 101 divided into two is placed on the endless belt conveyor 26a of the fifth conveying member 26 and conveyed to the chopping unit 8.

  The PET bottle main body 101 conveyed to the shredding unit 8 is shredded to 10 mm or less by the rotating tooth 82 and the fixed tooth 81a.

  In this embodiment, the plastic bottle processing apparatus 1 configured as described above is mounted and used on a vehicle body 201 of a plastic bottle processing apparatus-equipped vehicle 200 as shown in FIG.
