Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
(Example 1)
First, Embodiment 1 will be described with reference to FIGS. FIG. 1 is a side view showing an embodiment of the plastic bottle compressor of the present invention. FIG. 2 is a front view of the PET bottle compressor. FIG. 3 is a plan view of the PET bottle compressor. FIG. 4 is a plan view showing the first roller 30 and the second roller 40 of the PET bottle compressor. FIG. 5 is a side view of FIG.

  First, the configuration of the plastic bottle compressor will be described with reference to FIGS. Reference numeral 10 denotes a pyramid-shaped hopper. The hopper 10 includes an upper loading port 11 into which a plastic bottle (not shown) can be loaded from above, and a lower dropping port 12 from which the charged plastic bottle can be discharged from below. Reference numeral 20 denotes a compression chamber in which the four sides are joined by a steel plate or the like. The upper opening 21 of the compression chamber 20 and the lower drop opening 12 of the hopper 10 have the same opening size, and the hopper 10 is assembled above the compression chamber 20. For this reason, when a plastic bottle is introduced from the upper inlet 11 of the hopper 10, the introduced plastic bottle is supplied into the compression chamber 20. Reference numeral 22 denotes a carriage having wheels. The compression chamber 20 is placed on the upper surface 22 a of the carriage 22.

  As shown in FIG. 4, the first roller 30 and the second roller 40 are arranged in the same plane in the compression chamber 20. When this arrangement is described in detail, two first roller shafts 31 are formed at both ends of the first roller 30 so as to be integrated with the roller itself. Both the first roller shafts 31 are supported by two first roller bearings 32 provided on opposite side walls of the compression chamber 20.

  Similarly to the first roller 30, two second roller shafts 41 are formed at both ends of the second roller 40 so as to be integrated with the roller itself. Both the second roller shafts 41 are supported by two second roller bearings 42 provided on opposite side walls of the compression chamber 20. The sizes of the rollers 30 and 40 are, for example, “outer diameter 216 mm” and “axial length 400 mm”, and both the rollers 30 and 40 have a predetermined interval (for example, 12 mm) between both outer peripheral surfaces. They are juxtaposed so as to be separated. The rollers 30 and 40 can be rotated in the reverse direction by a power transmission system 60 described later. These two rollers 30 and 40 correspond to “a pair of roller bodies” recited in the claims.

  When both rollers 30 and 40 are rotated in the opposite directions (that is, in FIG. 5, the first roller 30 is counterclockwise and the second roller 40 is clockwise) on the outer peripheral surface of the first roller 30. A hooking claw 32 is provided so as to hook the plastic bottle paid out from the lower drop port 12 of the hopper 10 and to wind the hooked plastic bottle between the rollers 30 and 40. As is clear from the enlarged view of FIG. 5, the hooking claw 32 includes a hooking surface 32 a that protrudes substantially in the radial direction so that it becomes a resistance when the roller rotates and it is easy to hook the PET bottle. The protruding height of the hooking surface 32a is 10 mm.

  The arrangement of the hooking claws 32 will be described in detail. As is apparent from FIG. 5, eight hooking claws 32 are arranged in the outer circumferential direction of the first roller 30 so as to divide the outer circumferential direction into eight equal parts. As is clear from FIG. 45, the hooking claw 32 is positioned at 100 mm, 200 mm, and 300 mm from the left end in the axial direction of the first roller 30 when the left end of the roller 30 is considered as a reference (0 mm). A total of three are arranged. Therefore, a total of 24 (8 × 3 = 24) hooking claws 32 are arranged on the first roller 30.

  Further, similarly to the hooking claws 32, hooking claws 42 having hooking surfaces 42 a are projected on the outer peripheral surface of the second roller 40. The arrangement of the hooking claws 42 will be described in detail. As is clear from FIG. 5, the hooking claws 42 divide the outer circumferential direction into eight equal parts in the outer circumferential direction of the second roller 30 as in the hooking claws 32. Are arranged. Further, as apparent from FIG. 4, in the axial direction of the second roller 40, the hooking claw 42 is 25 mm, 50 mm, 75 mm, 125 mm from the left end when the left end of the roller 40 is considered as a reference (0 mm). , 150 mm, 175 mm, 225 mm, 250 mm, 275 mm, 325 mm, 350 mm, and 375 mm in total. Therefore, a total of 96 (8 × 12 = 96) hooking claws 42 are arranged on the second roller 40.

  When both the hooking claws 32 and 42 are arranged in this way, the left ends in the axial direction of both the rollers 30 and 40 coincide with each other, so that at least one of the hooking claws 32 and 42 is arranged at an interval of 25 mm from the left end. Will be. This arrangement interval of 25 mm is a numerical value selected so as to be equal to or less than the height of the cap of the PET bottle. This means that the interval between the hooking claws when the hooking claws of both roller bodies are considered to be positioned on the straight line in the axial direction of the roller body is the height of the cap of the PET bottle. Is less than or equal to ".

  Returning to FIGS. 1 to 3, reference numeral 50 denotes a motor that rotates both rollers 30 and 40, and is placed on the upper surface 22 a of the carriage 22. The rotation of the output shaft 51 of the motor 50 is transmitted to both the rollers 30 and 40 via the power transmission system 60. The power transmission system 60 will be described in detail. The power transmission system 60 includes a first transmission sprocket 61 fastened to the output shaft 51 of the motor 50, a first bearing 62 mounted on the upper surface 22 a of the carriage 22, and a second bearing. The second transmission sprocket 65, the third transmission sprocket 66, the fourth transmission sprocket 67, the third bearing 68 mounted on the upper surface 22a of the carriage 22, and the second transmission sprocket 65, the third transmission sprocket 66, and the fourth transmission sprocket 66 fastened to the first transmission shaft 64 supported by the bearing 63. A fifth transmission sprocket 71 and a sixth transmission sprocket 72 fastened to the second transmission shaft 70 supported by the four bearings 69; a seventh transmission sprocket 73 fastened to the first roller output shaft 31 of the first roller 30; The eighth transmission sprocket 74 is fastened to the second roller output shaft 41 of the second roller 40.

  The first transmission sprocket 61 and the second transmission sprocket 65 are linked by a first chain 74. Further, the third transmission sprocket 66 and the fifth transmission sprocket 71 are arranged so that gears formed on the outer peripheral surfaces of the third transmission sprocket 66 and the fifth transmission sprocket 71 are engaged with each other. Further, the fourth transmission sprocket 67 and the seventh transmission sprocket 73 are linked by a second chain 75. Further, the sixth transmission sprocket 72 and the eighth transmission sprocket 74 are linked by a third chain 76. The rollers 30 and 40 can be rotated in the reverse direction by the power transmission system 60.

  Subsequently, the operation of the plastic bottle compressor having the above-described configuration will be described. When a plastic bottle is introduced from the upper inlet 11 of the hopper 10, the introduced plastic bottle is supplied above both rollers 30 and 40 in the compression chamber 20. The supplied plastic bottle is hooked on the hooking surfaces 32a and 42a of the hooking claws 32 and 42 formed on the rollers 30 and 40 and is wound between the rollers 30 and 40.

  By this entrainment, the PET bottle is compressed so that the distance between the outer peripheral surfaces of both rollers 30 and 40 is 12 mm or less. Further, as already described, since the two hooking claws 32 and 42 are arranged at intervals equal to or less than the height of the PET bottle cap, the PET bottle cap is hooked on either of the two hooking claws 32 or 42. It is compressed in the state. Thereby, the cap of a plastic bottle can be crushed by the both hooking claws 32 and 42 without fail. The compressed PET bottle is discharged below the rollers 30 and 40. It takes only a few seconds from the input to the discharge of the PET bottle.

  In this way, even when it is desired to compress a large amount of PET bottles, the PET bottles can be efficiently crushed without much labor and time.

(Example 2)
Next, Example 2 will be described with reference to FIG. FIG. 6 is a plan view showing different embodiments of the first roller 30 and the second roller 40 in the plastic bottle compressor. In the second embodiment, the arrangement positions of the two hooking claws 32 and 42 in the axial direction of the two rollers 30 and 40 are changed as compared with the first embodiment already described. In the following description, the same or equivalent members as those in the first embodiment are denoted by the same reference numerals in the drawings, and redundant description is omitted. The same applies to Example 3 described later.

A total of seven are arranged at a position of 375 mm. Note that eight hooking claws 32 are arranged in the outer circumferential direction as in the first embodiment. Therefore, a total of 56 (7 × 8 = 56) hooking claws 32 are arranged on the first roller 30.

  Further, in the axial direction of the second roller 40, when the left end of the roller 40 is considered as a reference (0 mm), the hooking claw 42 is 25 mm, 50 mm, 125 mm, 150 mm, 225 mm, 250 mm, 325 mm, 350 mm from the left end. A total of eight are arranged in the position. In addition, the arrangement of the hooking claws 42 in the outer peripheral direction is eight as in the first embodiment. Therefore, a total of 64 (8 × 8 = 56) hooking claws 42 are arranged on the second roller 40. In the second embodiment, configurations other than the configuration described above are the same as those in the first embodiment.

  When the both hooking claws 32 and 42 are arranged in this way, the left ends in the axial direction of both rollers 30 and 40 are coincident with each other. Therefore, as in the first embodiment, at least one of the hooking claws at an interval of 25 mm from the left end. 32 and 42 are arranged. Therefore, this second embodiment can also obtain the same effects as the first embodiment.

FIG. 8 is a side view of FIG. In the third embodiment, the hooking claw 33 formed on the first roller 30 enters the outer peripheral surface of the second roller 40 as compared with the first embodiment already described.

  As shown in FIGS. 7 to 8, on the outer peripheral surface of the first roller 30, similarly to the hooking claws 32 in the first embodiment, hooking claws 33 are projected. The protruding height of the hooking surface 33a of the hooking claw 33 is 15 mm.

  Further, three cutout grooves 43 are formed on the outer peripheral surface of the second roller 40 in the outer peripheral direction. These three cutout grooves 43 are formed at positions facing the hooking claws 32 of the first roller 30. Moreover, the groove depth of these three notch grooves 43 is 5 mm, for example. In the third embodiment, configurations other than the configuration described above are the same as those in the first embodiment.

  When the hooking claw 33 and the notch groove 43 are arranged in this manner, the front end of the hooking claw 33 is put into the notch groove 43. Therefore, when compared with Example 1, the degree of compression of the PET bottle can be increased.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In each embodiment, the case where the sizes of both rollers 30 and 40 are “outer diameter 216 mm” and “axial length 400 mm” has been described. However, it is not limited to this. Each of these sizes is a design matter determined by the amount of PET bottles to be processed.
