Japanese Patent No. 3701430 Japanese Patent No. 4089362 Japanese Patent Publication No. 61-29859 Japanese Patent No. 2846691 Japanese Patent Publication No.59-33287 JP 2008-302705 A

  A conventional reversing mechanism includes a gripping mechanism. The gripping mechanism grips individual preforms. For example, the preform is sandwiched between two members. The two members are opened and closed with respect to each other. A complicated drive mechanism is required for opening and closing the member. The complexity of the drive mechanism increases the manufacturing cost of the reversing mechanism.

  This invention is made | formed in view of the said actual condition, and it aims at providing the inversion apparatus which can invert an object with a simple structure. An object of the present invention is to provide a preform handling apparatus using such a reversing apparatus.

  In order to achieve the above object, according to an aspect of the present invention, a reversing device is supported on a support body and the support body so as to be rotatable about a rotation axis, and has a first end in an axial direction of the rotation shaft. A rotating body partitioned by a second end on the opposite side, at least one sliding path formed on the rotating body for sliding an object from the first end to the second end, and at the first end A first guide path facing the inlet of the at least one slip path and guiding the object in a first position to the entrance of the at least one slip path; and the at least one slip path at the second end. And a second guide path that guides the object in the second posture reversed from the first posture in accordance with the rotation of the rotating body from the outlet of the at least one sliding road.

  In such a reversing device, the object is guided from the first guide path to the slip path. The object is inverted from the first posture to the second posture in accordance with the rotation of the rotating body. The object in the second posture is guided from the slip road to the second guide path. In this way, the object can be reversed with a simple configuration.

  The rotating shaft may be inclined so as to be installed at a position higher in the direction of gravity on the first end side than on the second end side. At this time, the reversing device is supported by the support body and stops the object in a posture other than the second posture that slides from the first end toward the second end, and the reversing device It is desirable to further include a restraining member that allows movement of the object in the second posture from the exit to the second guide path. In such a reversing device, the object can slide down the sliding road by the action of gravity. The object can be introduced onto the rotating body and discharged from the rotating body without application of a special driving force.

  The at least one slip path includes two slip paths arranged at a first position facing the first guide path and a second position facing the second guide path when the rotating body stops. Can be included. If it carries out like this, carrying in of the target object from a 1st guide way and carrying out of a target object to a 2nd guide way can be performed simultaneously.

  The at least one slip path may further include one or a plurality of slip paths between the first position and the second position in a circumferential direction of the rotating body. If it carries out like this, a target object can be introduce | transduced on a rotary body for every small rotation angle, and can be withdrawn. As the number increases, the inversion processing time can be shortened.

  The at least one sliding path is supported by the rotating body, faces outward from the rotating shaft, and extends from the first end to the second end, and is supported by the rotating body. And a first edge that extends between the first end and the second end to define a first edge extending between the first end and the second end while sandwiching an arbitrary space with the main slide surface. The first end and the first end are spread between the first end and the second end while sandwiching an arbitrary space between the auxiliary slide surface and the rotating body and sandwiching an arbitrary space between the first end and the second end. And a second auxiliary slide surface defining a second edge extending parallel to the first edge between the two ends.

  The slip of the object is guided at the first edge and the second edge. When the first and second auxiliary slide surfaces are positioned below the main slide surface in the direction of gravity, the object is received by the first and second auxiliary slide surfaces in the first posture during movement. On the other hand, when the main slide surface is positioned below the first and second auxiliary slide surfaces in the direction of gravity, the object is received by the main slide surface in the second posture reversed from the first posture during the movement. Thus, the object is reversed according to the rotation of the rotating body by 180 degrees.

  The distance between the first end and the restraining member may be set to a size that holds the row of the objects that abut against the restraining member between the first edge and the second edge. Thus, a plurality of objects can be held between the pair of first and second edges. Such a configuration contributes to shortening the processing time.

  The reversing device may further include a main slide surface member that is formed on the surface of the main slide surface and is attached to the rotary body so as to be displaceable in a radial direction of a circle drawn around the rotation axis. In such a reversing device, the distance between the main slide surface and the first and second auxiliary slide surfaces can be adjusted. The distance between the main slide surface and the first and second auxiliary slide surfaces is appropriately set according to the size of the part of the object arranged between the main slide surface and the first and second auxiliary slide surfaces. be able to. The reversing device can accommodate objects of various sizes.

  The reversing device may further include a first auxiliary slide surface member that forms the first auxiliary slide surface and moves in parallel with the main slide surface to increase or decrease the distance between the first edge and the second edge. . The reversing device may further include a second auxiliary slide surface member that forms the second auxiliary slide surface and moves in parallel with the main slide surface to increase or decrease the distance between the first edge and the second edge. . In such a reversing device, the distance between the first edge and the second edge can be adjusted. The distance between the first edge and the second edge can be appropriately set according to the size of the portion of the object guided between the first edge and the second edge. The reversing device can accommodate objects of various sizes.

  In addition, the main slide surface may be widened in parallel to the rotation axis. However, the main slide surface does not necessarily have to extend parallel to the rotation axis. The main slide surface may be inclined with respect to the rotation axis. According to such an inclination, the object can be slid down at different down speeds when the object is introduced and withdrawn.

  The first edge and the second edge may extend in parallel to the rotation axis. However, the first edge and the second edge do not necessarily have to extend parallel to the rotation axis. As long as the passage of the object is not hindered between the first edge and the second edge, the first edge and the second edge may be curved and may be interrupted.

  The first auxiliary slide surface and the second auxiliary slide surface only need to extend in parallel to the main slide surface. However, the first auxiliary slide surface and the second auxiliary slide surface need not necessarily extend parallel to the main slide surface. The first auxiliary slide surface and the second auxiliary slide surface may be inclined or curved with respect to the main slide surface unless the first and second auxiliary slide surfaces and the main slide surface prevent the object from descending. Good.

  The main slide surface may be a flat surface. The first auxiliary slide surface and the second auxiliary slide surface may be widened in one virtual plane parallel to the main slide surface. However, the main slide surface does not necessarily have to be a flat surface. The first auxiliary slide surface and the second auxiliary slide surface need not necessarily extend within one virtual plane parallel to the main slide surface. The first auxiliary slide surface, the second auxiliary slide surface, and the main slide surface may be curved or may be interrupted as long as the first and second auxiliary slide surfaces and the main slide surface do not prevent the object from sliding down.

FIG. 12 is a diagram for simply explaining the operation of the inverting device corresponding to FIG. 11.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 schematically shows a partial configuration of a preform handling apparatus 11. The preform handling device 11 performs a predetermined process on a predetermined preform. The preform after processing is put into, for example, a blow molding machine (not shown). A blow molding machine molds, for example, a container from a preform. The preform is injection-molded from a resin material such as PET (polyethylene terephthalate). Here, the preform handling device 11 realizes crystallization processing of the mouth portion of the preform. The heat resistance of the mouth is increased according to crystallization.

  The preform handling device 11 includes a crystallization device 12 and a preform supply device 13 (only part of which is shown in FIG. 1). The preform is supplied from the preform supply device 13 to the crystallization device 12. The preforms are arranged in a row for delivery.

  The crystallization device 12 includes a transport device 14. The transport device 14 includes, for example, a plurality of sprockets 15. An endless chain belt 16 is wound around the sprocket 15. The chain belt 16 includes a conveyance table 17. A preform is held on the transfer table 17.

  The crystallization device 12 includes a heating device 18. The heating device 18 includes a heater 19. When the transfer table 17 moves, the preform on the transfer table 17 passes between the heaters 19. In this way, heat is applied from the heater 19 to the preform.

  The crystallization device 12 includes a preform delivery device 21 and a preform take-out device 22. The preform delivery device 21 and the preform take-out device 22 are connected to the transport device 14. The preform is supplied from the preform supply device 21 toward the conveyance table 17. The preform delivery device 21 delivers the preforms one by one from the preform supply device 13 to the transport table 17 one by one. The preform take-out device 22 removes the preforms after the heat treatment in turn one by one from the transport table 17.

  As shown in FIG. 2, the chain belt 16 includes an outer link 23 and an inner link 24. The pin 25 of the outer link 23 passes through the bush 26 of the inner link 24. A roller 27 is rotatably mounted on the pin 25 inside the inner link 24. The chain belt 16 meshes with the sprocket 15 with a roller 27.

  A transport table 17 is formed on the outer link 23. The transport table 17 includes a pair of receiving members 28. The receiving member 28 is fixed to the tip of the shaft member 29. The shaft member 29 is supported by the pin 25 so as to be slidable in the axial direction of the pin 25 with respect to the pin 25. The receiving member 28 receives the bottom surface of the preform P in the inverted posture at the uppermost position of the shaft member 29. At the lowest position of the shaft member 29, the receiving member 28 is completely separated from the space in the preform P in the inverted posture.

  The transport table 17 includes a pair of cylindrical members 31 corresponding to the receiving members 28. The cylindrical member 31 is coupled to the shaft member 29. The cylindrical member 31 enters the mouth portion of the preform P in the inverted posture at the uppermost position. In response to the approach, the cylindrical member 31 positions the mouth in a plane orthogonal to the axis of the pin 25. The cylindrical member 31 is completely separated from the space in the preform P in the inverted posture at the lowest position.

  The transport table 17 includes a shielding plate 32. The shielding plate 32 is coupled to the slide member 33. At the uppermost position of the slide member 33, the shielding plate 32 covers the preform P other than the mouth, that is, the body of the preform P. At the lowest position of the slide member 33, the shielding plate 32 is completely detached from the preform P in the inverted posture.

  Assume that the crystallization apparatus 12 crystallizes the mouth of the preform P. Here, a wide-mouth container is molded from the preform P. As shown in FIG. 3, the preform P includes a mouth portion 36 that is relatively large with respect to the body 35, so that the preform P can stand by itself in an inverted posture on the horizontal plane HR. The mouth portion 36 is formed in a cylindrical body. A thread is formed on the outer peripheral surface of the mouth. The central axis 37 of the preform P, that is, the central axis 37 of the mouth portion 36 is orthogonal to the horizontal plane HR. In addition, since the height of the body 35 is set relatively low with respect to the size of the mouth portion 36, the preform P is stabilized in the inverted posture. On the other hand, as shown in FIG. 4, since the bottom surface of the body 35 of the preform P is rounded, the preform P in the upright posture cannot stand upright on the horizontal plane HR. In other words, the preform P in the upright posture cannot be held on the horizontal plane HR while the central axis 37 of the mouth portion 36 is orthogonal to the horizontal plane HR. In the preform P, a so-called support ring or flange 38 is formed between the mouth portion 36 and the body 35. The flange 38 extends outward along a plane perpendicular to the central axis 37 of the mouth portion 36. When the preform P is supported by the flange 38 on the horizontal plane SR that is separated by a predetermined interval, the body 35 of the preform P enters between the horizontal planes SR. The central axis 37 of the mouth 36 can be orthogonal to the horizontal plane SR. In the inverted posture, the mouth portion 36 opens downward. On the other hand, in the upright posture, the mouth portion 36 opens upward.

  When the crystallizer 12 is activated, the chain belt 16 circulates. The preforms P are supplied from the preform supply device 13 to the transport device 14 one by one. As the chain belt 16 circulates, the transport table 17 enters the heating device 18. Prior to entering, the body 35 of the preform P is covered with a shielding plate 32. Only the mouth 36 of the preform P is exposed to the heat of the heater 19. Thus, the mouth portion 36 of the preform P is crystallized. Heat resistance is imparted to the mouth portion 36 of the preform P. Thereafter, as the chain belt 16 circulates, the transport table 17 leaves the heating device 18. After leaving, the slide member 33 moves to the lowest position. As a result, the entire preform P is exposed. Cooling of the preform P is promoted. The preform take-out device 22 removes the preform P after cooling from the transport table 17. Thus, the processing of the preform P is completed.

  Here, the structure of the preform supply apparatus 13 will be described in detail. As shown in FIG. 5, the preform supply device 13 includes a preform alignment device unit 39. The preform aligner unit 39 includes an alignment path 41 that is inclined at a predetermined inclination angle. The alignment path 41 includes an inlet end 42 and an outlet end 43. The inlet end 42 is positioned higher in the direction of gravity than the outlet end 43. A plurality of preforms P are supplied to the alignment path 41 from the inlet end 42 apart. In the alignment path 41, the preforms P are aligned in a line in an upright posture. The preforms P in the upright posture are discharged from the outlet end 43 one by one.

  A reversing device RM is connected to the preform aligning unit 39. The reversing device RM includes a first slide conveyor 45, a reversing unit 46, and a second slide conveyor 47. The first slide conveyor 45 includes a slide surface 48 that is inclined at a predetermined inclination angle. The slide surface 48 includes an inlet end 49 and an outlet end 51. The inlet end 49 is positioned higher than the outlet end 51 in the direction of gravity. The slide surface 48 is connected to the outlet end 43 of the alignment path 41 at the inlet end 49. For example, the slide surface 48 spreads within one inclined plane. The slide surface 48 is divided into two by a gap extending from the inlet end 49 to the outlet end 51. The gap extends with a uniform width between the edges of the slide surface 48. The edges of the slide surface 48 are defined on straight lines extending parallel to each other. The interval between the slide surfaces 48 is set larger than the outer diameter of the body 35 of the preform P. However, the interval between the slide surfaces 48 is set smaller than the outer diameter of the flange 38 of the preform P. The preform P in the upright posture is supported on the slide surface 48 by the flange 38. The body 35 of the preform P is suspended from the gap. The preforms P can slide down the first slide conveyor 45 one by one in an upright posture. The first slide conveyor 45 functions as a first guide path.

  A reversing unit 46 is connected to the first slide conveyor 45. The reversing unit 46 includes a rotating body 52. The rotator 52 rotates around a rotation shaft 53 inclined at a predetermined inclination angle. The inclination angle of the rotating shaft 53 of the rotating body 52 is adjusted to the inclination angle of the slide surface 48 of the first slide conveyor 45. The preform P in the upright posture is supplied from the first slide conveyor 45 to the rotating body 52. The preform P is temporarily held on the rotating body 52 in a specified direction. When the rotating body 52 rotates at a rotation angle of 180 degrees, the posture of the preform P is reversed.

  A second slide conveyor 47 is connected to the reversing unit 46. The second slide conveyor 47 includes a slide surface 54. The slide surface 54 includes an inlet end 55 and an outlet end 56. The inlet end 55 is positioned higher in the direction of gravity than the outlet end 56. The slide surface 54 is inclined at a predetermined inclination angle at the entrance end 55. This inclination angle is adjusted to the inclination angle of the rotating shaft 53 of the rotating body 52. The slide surface 54 extends along the horizontal plane at the exit end 56. Therefore, the slide surface 54 is gently curved from the inclined posture to the horizontal posture. The preform P in an inverted posture is supplied from the rotating body 52 to the second slide conveyor 47. The preforms P can slide down the second slide conveyor 47 one by one with the inverted posture. Thus, the preforms P in the inverted posture are delivered to the preform delivery device 21 one by one. The second slide conveyor 47 functions as a second guide path.

  In the preform supply device 13, an inclined conveyor 57 is connected to the preform alignment device unit 39. As shown in FIG. 6, the inclined conveyor 57 includes a conveyance path 58 that is inclined at a predetermined inclination angle. The larger the inclination angle of the inclined conveyor 57 is, the smaller the installation area of the inclined conveyor 57 is. The conveying path 58 is connected at an end point 59 to the inlet end 42 of the alignment path 41 of the preform aligner unit 39. The starting point 61 of the conveyance path 58 is connected to the bottom of the hopper 62. A plurality of preforms P are stored in the hopper 62. The inclined conveyor 57 scoops up the preform P from the hopper 62. The inclined conveyor 57 conveys the preform P from the hopper 62 to the preform aligner unit 39. According to such a combination of the preform aligning unit 39, the hopper 62, and the inclined conveyor 57, the preforms P do not need to be aligned in advance, and human work can be avoided as much as possible. Work efficiency can be increased.

  Next, the structure of the preform aligning unit 39 will be briefly described with reference to FIG. The preform aligner unit 39 includes a pair of rollers 63. The rollers 63 extend parallel to each other. The axis of the roller 63 is orthogonal to a common horizontal line. An interval is formed between the rollers 63. The size of the interval is set smaller than the outer diameter of the flange 38 of the preform P. The rollers 63 rotate in opposite directions around the axis. According to the rotation, the outer surface of the roller 63 traces the space of the interval upward. The roller 63 forms the alignment path 41 described above. The preform P gradually descends from the inlet end 42 to the outlet end 43 of the alignment path 41 by the action of gravity. During the lowering, the preform P changes its posture by the action of the rotation of the roller 63. Moreover, since the distance between the rollers 63 is less than one preform, the preforms P are arranged in a row between the rollers 63.

  The preform alignment device unit 39 includes a guide member 64. The guide member 64 is disposed above the roller 63. The guide member 64 has a guide surface 65 that extends parallel to the axis of the roller 63. As the guide surface 65 approaches the roller 63, the interval gradually decreases. The guide member 64 guides the preform P toward the interval between the rollers 63.

  An impeller 66 is disposed in front of the outlet end 43 of the alignment path 41. The impeller 66 rotates around the horizontal axis. The impeller 66 includes a rotating blade 67. The rotary blades 67 are arranged at regular intervals around the horizontal axis, for example. Here, for example, twelve rotating blades 67 are attached. The rotary blade 67 rotates so as to trace the space between the rollers 63 from the bottom to the top. When the preform P is held between the rollers 63 in a posture other than the upright posture, the preform P is flipped up by the rotating blades 67 of the impeller 66. The preform P jumps to the upstream side of the alignment path 41. Even if the preform P is in an upright posture, if the two or more preforms P are held between the rollers 63 while being overlapped, the preform P is flipped up by the rotating blades 67 of the impeller 66. . Thus, the preform P is again exposed to the action of the roller 63. If one preform P correctly enters between the rollers 63 in an upright posture, the preform P passes through the rotary blade 67. Contact between the rotary blade 67 and the preform P is avoided. The preform P can reach the outlet end 43 of the alignment path 41.

  Each rotating blade 67 includes a blade body 68. The rotary blade 67 is connected to a horizontal axis, that is, a rotary shaft by a blade body 68. The blade body 68 extends along a virtual plane including one radiation of the rotation axis. As shown in FIG. 8, a pair of left and right first claw members 69 are attached to the blade body 68 in front view. The first claw member 69 may be fixed with a screw, for example. The first claw members 69 are separated from each other at a predetermined interval in the horizontal direction. The first claw members 69 are opposed to each other on the vertical surface 71. The vertical surface 71 is formed by a plane extending parallel to the axis of the roller 63. The interval between the vertical surfaces 71 is set to a size obtained by adding a predetermined gap to the outer diameter of the flange 38 of the preform P. Therefore, if one preform P correctly enters between the rollers 63 in an upright posture, the preform P can pass between the first claw members 71.

  In each rotary blade 67, a corresponding auxiliary claw member 72 is attached to each pair of first claw members 69. The auxiliary claw member 72 may be fixed with a screw, for example. The tips of the auxiliary claw members 72 protrude from the corresponding vertical surfaces 71 in directions approaching each other. As shown in FIG. 8, the tip of the auxiliary claw member 72 is disposed outside the outline of the preform P that enters between the rollers 63 in an upright posture. Therefore, if one preform P correctly enters between the rollers 63 in an upright posture, the preform P can pass between the auxiliary claw members 72. On the other hand, the tip of the auxiliary claw member 72 is a preform P that enters between the rollers 63 in a rollover posture, that is, is supported between the rollers 63 and has a central axis 37 parallel to the axis of the rollers 63. It contacts the contour of the preform P to be placed. Therefore, if the preform P is supported between the rollers 63 in a rollover posture, the preform P is flipped up by the auxiliary claw member 72. The preform P jumps to the upstream side of the alignment path 41.

  In the specific rotating blade 67, one second claw member 73 is attached to the blade body 68. The second claw member 73 may be fixed with a screw, for example. The second claw member 73 is disposed between virtual vertical surfaces including the vertical surface 71. The second claw member 73 includes a pair of claws 74. The 2nd nail | claw member 73 is arrange | positioned on the outer side from the outline of the preform P which approachs between the rollers 63 with an upright posture correctly. Therefore, if one preform P correctly enters between the rollers 63 in an upright posture, the preform P can pass through the second claw member 73. On the other hand, the tip of the claw 74 is disposed at a position where it collides with the preform P that enters between the rollers 63 in a state of overlapping in an upright posture. Therefore, even if the preform P is in the upright posture, if the two or more preforms P are held between the rollers 63 while being overlapped, the preform P is flipped up by the claws 74. For example, the second claw members 73 may be attached by all the rotary blades 67 or may be attached only by a specific rotary blade 67 every other one.

  As shown in FIG. 9, the reversing unit 46 includes a support 78. The rotating shaft 53 is fixed to the support body 78. The rotating body 52 is rotatably mounted on the rotating shaft 53. In this way, the rotating body 52 is supported by the support 78 so as to be rotatable around the rotation shaft 53. The rotating body 52 is partitioned in the axial direction of the rotating shaft 53 by a first end 52a, that is, an upstream end, and a second end 52b, that is, a downstream end. The first end 52a and the second end 52b are formed of end plates.

  The rotating body 52 supports a main slide surface member 81, a first auxiliary slide surface member 82, and a second auxiliary slide surface member 83. The main slide surface member 81 has a main slide surface 84. The main slide surface 84 faces outward from the rotation shaft 53. The main slide surface 84 is configured by a plane extending from the first end 52 a of the rotating body 52 to the second end 52 b of the rotating body 52. The plane is interrupted at the first end 52a and the second end 52b of the rotating body 52, respectively. The main slide surface 84 extends parallel to the axis of the rotation shaft 53. The main slide surface 84 is orthogonal to a virtual plane including the axis of the rotation shaft 53. The main slide surface 84 is formed smoothly with a surface roughness that allows the preform P to slide.

  The main slide surface member 81 has a pair of attachment pieces 85. Each attachment piece 85 extends along a plane orthogonal to the axis of the rotation shaft 53. The attachment piece 85 is superposed on the end surface of the rotating body 52, that is, the surface of the end plate, at the first end 52 a and the second end 52 b of the rotating body 52. As a result, the main slide surface member 81 can be displaced relative to the axis of the rotation shaft 53 while maintaining the parallel relationship of the main slide surface 84 with respect to the axis of the rotation shaft 53.

  Each attachment piece 85 is formed with a pair of long holes 86. The long holes 86 extend parallel to each other. A center line 86 a of the long hole 86 is set parallel to a virtual plane including the axis of the rotation shaft 53. A screw 87 is inserted into the long hole 86. The screw 87 is screwed into the end face, that is, the end plate of the rotating body 52. The attachment piece 85 is sandwiched between the screw head of the screw 87 and the end face of the rotating body 52. In this way, the attachment piece 85, that is, the main slide surface member 81 is fixed to the rotating body 52. Since the screw 87 is received in the long hole 86, the main slide surface member 81 can be displaced in the radial direction of a circle drawn around the rotation axis 56.

  The first auxiliary slide surface member 82 has a first auxiliary slide surface 88. The first auxiliary slide surface 88 sandwiches an arbitrary space between the main slide surface 84. The first auxiliary slide surface 88 is configured by a plane extending from the first end 52 a of the rotating body 52 to the second end 52 b of the rotating body 52. The plane is interrupted at the first end 52 a and the second end 52 b of the rotating body 52. The first auxiliary slide surface 88 extends parallel to the axis of the rotation shaft 53. The first auxiliary slide surface 88 extends in one virtual plane parallel to the main slide surface 84.

  The second auxiliary slide surface member 83 has a second auxiliary slide surface 89. The second auxiliary slide surface 89 sandwiches an arbitrary space between the main slide surface 84. The second auxiliary slide surface 89 is configured by a plane extending from the first end 52 a of the rotating body 52 to the second end 52 b of the rotating body 52. The plane is interrupted at the first end 52 a and the second end 52 b of the rotating body 52. The second auxiliary slide surface 89 extends parallel to the axis of the rotation shaft 53. The second auxiliary slide surface 89 extends in a virtual plane including the first auxiliary slide surface 88.

  The first auxiliary slide surface member 82 and the second auxiliary slide surface member 83 sandwich a space adjacent to the main slide surface 84. The first auxiliary slide surface 88 defines a first edge 88a in contact with the space. Similarly, the second auxiliary slide surface 89 defines a second edge 89a in contact with the space. The first edge 88 a and the second edge 89 a extend from the first end 52 a of the rotating body 52 to the second end 52 b of the rotating body 52. The first edge 88a and the second edge 89a extend in parallel with each other while facing each other. The first edge 88 a and the second edge 89 a are set parallel to the axis of the rotation shaft 53.

  The first auxiliary slide surface member 82 has an attachment piece 91. The attachment piece 91 extends along a plane extending parallel to the main slide surface 84. The attachment piece 91 is overlapped on the side surface of the rotating body 52 between the first end 52 a and the second end 52 b of the rotating body 52. As a result, the first auxiliary slide surface member 82 can be displaced relative to the axis of the rotary shaft 53 while maintaining the parallel relationship of the first auxiliary slide surface 88 with respect to the axis of the rotary shaft 53. it can.

  A pair of long holes 92 are formed in the attachment piece 91. The long holes 92 extend parallel to each other. A center line 92 a of the long hole 92 is set in a virtual plane orthogonal to the axis of the rotation shaft 53. A screw 93 is inserted into the long hole 92. The screw 93 is screwed into the side surface of the rotating body 52. The attachment piece 91 is sandwiched between the screw head of the screw 93 and the side surface of the rotating body 52. Thus, the attachment piece 91, that is, the first auxiliary slide surface member 82 is fixed to the rotating body 52. Since the screw 93 is received in the long hole 92, the first auxiliary slide surface 88 is displaced parallel to the main slide surface 84, and the distance between the first edge 88a and the second edge 89a can be increased or decreased.

  Similarly, the second auxiliary slide surface member 83 has an attachment piece 94. The attachment piece 94 extends along a plane extending parallel to the main slide surface 84. The attachment piece 94 is overlapped on the side surface of the rotating body 52 between the first end 52 a and the second end 52 b of the rotating body 52. As a result, the second auxiliary slide surface member 83 can be displaced relative to the axis of the rotary shaft 53 while maintaining the parallel relationship of the second auxiliary slide surface 89 with respect to the axis of the rotary shaft 53. it can.

  A pair of long holes 95 are formed in the attachment piece 94. The long holes 95 extend parallel to each other. A center line 95 a of the long hole 95 is set in a virtual plane orthogonal to the axis of the rotation shaft 53. A screw 96 is inserted into the long hole 95. The screw 96 is screwed into the side surface of the rotating body 52. The attachment piece 94 is sandwiched between the screw head of the screw 96 and the side surface of the rotating body 52. Thus, the attachment piece 94, that is, the second auxiliary slide surface member 83 is fixed to the rotating body 52. Since the screw 96 is received in the long hole 95, the second auxiliary slide surface 89 is displaced parallel to the main slide surface 84, and the distance between the first edge 88a and the second edge 89a can be increased or decreased.

  A plurality of spacer plates 97a and a plurality of pairs of gate slide plates 97b are attached to the first end 52a. A pair of gate slide plates 97b is combined with each spacer plate 97a. The spacer plate 97a and the gate slide plate 86b may be fixed to the first end 52a with screws, for example. The spacer plate 97a and the gate slide plate 97b are overlaid on the surface of the first end 52a. One set of spacer plate 97a and gate slide plate 97b are disposed between the main slide surface members 81, respectively.

  All the spacer plates 97 a and the gate slide plates 97 b have a smooth surface that extends in a plane perpendicular to the rotation shaft 53. The smooth surface is formed smoothly with a surface roughness that allows the preform P to slide. The smooth surface spreads along the movement trajectory of the first and second auxiliary slide surfaces 88 and 89 rotating around the rotation axis 53, that is, one virtual circle. Moreover, since the spacer plate 97a and the gate slide plate 97b have a predetermined thickness, the smooth surface is disposed on the upstream side in the axial direction from the upstream ends of the first and second auxiliary slide surface members 82 and 83. The spacer plate 97a and the gate slide plate 97b may be formed from, for example, a sliding resin material. The position of the gate slide plate 97b can be changed in parallel with the main slide surface 84 as shown in FIG. As a result, the gate slide plates 97b can approach each other and move away from each other across the space adjacent to the main slide surface 84.

  The reversing unit 46 further includes a restraining member 98. The restraining member 98 is supported by the support body 78. The restraining member 98 extends in a circumferential direction around the axis of the rotation shaft 53 with a predetermined length. A receiving surface 99 is defined on the restraining member 98. The receiving surface 99 extends in one virtual plane orthogonal to the axis of the rotation shaft 53. The receiving surface 99 defines an inner edge with a circular arc coaxial with the axis of the rotating shaft 53. The inner edge is arranged at a position away from each main slide surface 84 by a predetermined distance in a direction orthogonal to the main slide surface 84. At the same time, the inner edge of the restraining member 98 is disposed at a position away from the first end 52 a of the rotating body 52, that is, the upstream end by a predetermined distance in the axial direction of the rotating shaft 53.

  As shown in FIG. 10, the distance between the first edge 88a of the first auxiliary slide surface 88 and the second edge 89a of the second auxiliary slide surface 89 is smaller than the outer diameter D1 of the flange 38 of the preform P. Is set larger than the inner diameter D2. As described above, the gap between the first edge 88a of the first auxiliary slide surface 88 and the second edge 89a of the second auxiliary slide surface 89 can be increased or decreased by the action of the long hole 92 and the long hole 95. Depending on the size of the reform P, the distance between the first edge 88a and the second edge 89a can be set appropriately. The reversing unit 46 can accommodate various sizes of preforms P. In addition, the interval between the first edge 88 a and the second edge 89 a may be adjusted based on the replacement of the first auxiliary slide surface member 82 and the second auxiliary slide surface member 83. As is clear from FIG. 10, the first auxiliary slide surface 88 and the second auxiliary slide surface 89 have a size that extends outward from the outer diameter D1 of the preform P over their entire length.

  At the same time, the distance between the main slide surface 84 and the first and second auxiliary slide surfaces 88 and 89 is set to a size L2 obtained by subtracting the axial length of the body 35 from the axial length L1 of the preform P. (L2 + α), that is, a size obtained by adding a predetermined play α to the height L2 of the plane 101 that is in contact with the flange 38 from above when the preform P is installed on the horizontal plane 100 in an inverted posture. (L2 + α). As described above, since the distance between the main slide surface 84 and the first and second auxiliary slide surfaces 88 and 89 can be increased or decreased by the action of the long hole 86, the main slide surface according to the height of the mouth portion 36. The distance between 84 and the first and second auxiliary slide surfaces 88 and 89 can be set as appropriate. The reversing unit 46 can correspond to the mouth portions 36 of various sizes. In addition, the distance between the main slide surface 84 and the first and second auxiliary slide surfaces 88 and 89 may be adjusted based on the replacement of the main slide surface member 81. Similarly, the expansion of the main slide surface 84 is larger than the outer diameter of the mouth portion 36 of the preform P, and has a size capable of receiving the entire mouth portion 36.

  In the preform P, instead of the flange 38 described above, a flange that extends outward in a plane perpendicular to the central axis from the top surface of the mouth portion 36 in an upright posture, that is, an erect posture, is formed. Good. Even in this case, the distance between the main slide surface 84 and the first and second auxiliary slide surfaces 88 and 89 is such that the height of the plane 101 that comes into contact with the flange from above when the preform P is installed on the horizontal plane 100 in an inverted posture. What is necessary is just to set to the magnitude | size (L2 + (alpha)) which added predetermined play (alpha) to L2. In the present embodiment, for example, the main slide surface member 81 and the first and second auxiliary slide surface members 82 and 83 may be exchanged when setting such an interval.

  A combination of the main slide surface 84 and the first and second auxiliary slide surfaces 88 and 89 is arranged in the circumferential direction of the rotating body 52 over a plurality of sets. Here, six combinations are arranged at equal intervals in the circumferential direction with a pitch of a central angle of 60 degrees. However, the number of combinations is not limited to six. The number of combinations may be appropriately determined according to the size of the rotating body 52 and the size of the preform P. The individual combinations form the preform P runway 102. The downhill 102 of this embodiment functions as a slideway.

  As shown in FIG. 10, every time the rotating body 52 rotates at a rotation angle of 60 degrees, one of the downhill paths 102 is positioned at the lowest position PL. In the lowest position PL, the first and second auxiliary slide surfaces 88 and 89 and the slide surface 48 of the first slide conveyor 45 are adjacent to each other. The preform P slides down the runway 102 by its own weight. The sliding down of the preform P is stopped by a restraining member 98. Thus, the preform P is held on the rotating body 52. Each downhill 102 reaches the uppermost position PH via the first midway position P1 and the second midway position P2 at every rotation angle of 60 degrees from the lowermost position PL. The restraining member 98 extends from the lowest position PL to the second midway position P2 in the range of a central angle of 180 degrees. The stop member 98 is interrupted at the second midway position P2. During the rotation of the rotating body 52, the preform P slides on the inner edge of the restraining member 98. The preform P is continuously held on the rotating body 52 during rotation.

  When the downhill 102 reaches the uppermost position PH from the lowermost position PL through the first and second intermediate positions P1 and P2, the main slide surface 84 and the slide surface 54 of the second slide conveyor 47 are adjacent to each other. Since the stop member 98 is interrupted at the second midway position P2, the stop of the stop member 98 is released. As a result, the preform P slides down from the runway 102 by its own weight. The distance between the main slide surface 84 and the inner edge of the restraining member 98 is appropriately set based on the size and shape of the preform P.

  As shown in FIG. 11, the rotating body 52 and the rotating shaft 53 constitute a drive source, that is, a motor 104. For example, a stator 105 is fixed to the rotating shaft 53. The stator 105 may be composed of a permanent magnet, for example. For example, the rotor 106 is fixed to the rotating body 52. The rotor 106 surrounds the stator 105 around the rotation shaft 53. The rotor 106 may be composed of, for example, an electromagnetic coil. The electromagnetic coil generates a magnetic field in response to power supply. The motor 104 causes the rotating body 52 to rotate intermittently at a predetermined rotation angle.

  Each runway 102 includes an inlet end 107 and an outlet end 108. The inlet end 107 is positioned higher in the direction of gravity than the outlet end 108. When the downhill 102 is positioned at the lowest position PL, the first auxiliary slide surface 88 and the second auxiliary slide surface 89 are adjacent to the slide surface 48 of the first slide conveyor 45. That is, the inlet end 107 of the downhill 102 is opposed to the outlet end 51 of the first slide conveyor 45. Accordingly, the preform P can slide down from the first slide conveyor 45 to the downway 102. A specified number of preforms P can be received in one line on the downway 102. At the same time, when the downhill 102 is positioned at the uppermost position PH, the main slide surface 84 is adjacent to the slide surface 54 of the second slide conveyor 47. That is, the outlet end 108 of the downhill 102 is opposed to the inlet end 55 of the second slide conveyor 47. Therefore, the preform P can slide down from the downway 102 to the second slide conveyor 47. As described above, a rotation angle of 180 degrees is set between the lowermost position PL and the uppermost position PH. Therefore, the downhill 102 has the lowermost position PL and the uppermost position every rotation of the rotating body 52 by 180 degrees. You can move between PH.

  The reversing unit 46 includes a first detection sensor 111 and a second detection sensor 112. The first detection sensor 111 detects the preform P located at a position closest to the inlet end 107 in the downhill 102 located at the lowest position PL. With the function of the first detection sensor 111, it is confirmed whether or not the downhill 102 is filled with a specified number of preforms P. The second detection sensor 112 detects the preform P located at a position closest to the outlet end 108 in the downhill 102 located at the uppermost position PH. It is confirmed whether or not all the preforms P are discharged from the downhill 102 by the function of the second detection sensor 112. A so-called optical sensor may be used for the first detection sensor 111 and the second detection sensor 112.

  As shown in FIG. 12, a restriction mechanism 113 is attached to the first slide conveyor 45. The restriction mechanism 113 includes a restriction member 115. The restricting member 115 moves between the first position F1 and the second position B1. The restriction member 115 enters the movement path 116 of the preform P at the first position F1. The restricting member 115 at the first position F <b> 1 blocks the advance of the leading preform P on the first slide conveyor 45. At the second position B1, the regulating member 115 moves backward from the movement path 116 of the preform P. For example, a driving device such as an electromagnetic solenoid 117 is connected to the restriction member 115. The restriction member 115 can be displaced between the first position F1 and the second position B1 by the action of the electromagnetic solenoid 117.

  Next, the operation of the reversing unit 46 will be described in detail. When the preform aligning unit 39 operates, the preform P in the upright posture slides down the slide surface 48 of the first slide conveyor 45 in a line as shown in FIG. Three preforms P are slid down from the first slide conveyor 45 to the downhill 102 located at the lowest position PL. A prescribed number of preforms P enter the runway 102 in a row. The first preform P hits the stop member 98. When the first preform P comes into contact with the receiving surface 99 of the restraining member 98, three preforms P are received between the front end 56a and the rear end 56b of the rotating body 52. The preform P is maintained in an upright posture. When the downhill 102 is filled with the three preforms P, the advance of the fourth preform P from the head, that is, the stop member 98, is blocked in the first slide conveyor 45. Thus, the fourth and subsequent preforms P remain in the first slide conveyor 45. The preform P is stored on the first slide conveyor 45. A sufficient number of preforms P accumulate at the outlet end 51 of the first slide conveyor 45.

  As shown in FIG. 13, when the three preforms P slide on the first and second auxiliary slide surfaces 88 and 89 and enter the downhill 102, the first detection sensor 111 outputs a detection signal. It is confirmed by the action of this detection signal that the downhill 102 is filled with the prescribed number of preforms P. A drive signal is supplied to the motor 104 of the reversing unit 46 in accordance with the output of the detection signal. The rotating body 52 rotates at a rotation angle of 60 degrees. The downhill 102 at the lowest position PL moves to the first midway position P1. At this time, the leading preform P slides on the stop member 98 in the downhill 102. The restraining member 98 restrains the preform P from sliding down. Three preforms P are held in the downhill 102. At the same time, the first preform P on the first slide conveyor 45 slides on the smooth surfaces of the spacer plate 97a and the gate slide plate 97b between the pair of downhill paths 102. The spacer plate 97a and the gate slide plate 97b prevent the preform P from sliding down. When an empty downhill 102 is newly positioned at the lowest position PL, three new preforms P enter the downhill 102. Thus, every time the empty downhill 102 moves to the lowest position PL, three preforms P are received in the downhill 102.

  When the rotating body 52 further rotates at a rotation angle of 60 degrees, the downhill 102 at the first midway position P1 moves to the second midway position P2. The first preform P continues to slide on the stop member 98 in the downway 102. The three preforms P continue to be held in the downhill 102. When the rotating body 52 further rotates at a rotation angle of 60 degrees, the downhill 102 at the second midway position P2 moves to the uppermost position PH. Thus, the rotation angle of the downhill 102 reaches 180 degrees by the intermittent rotation of the rotating body 52 by 3 degrees. When the downhill 102 reaches the uppermost position PH, the preform P in the downhill 102 is received by the main slide surface 84 in an inverted posture. Since the stop member 98 is interrupted at the second midway position P2, the preform P loses its support at the uppermost position PH. Therefore, the preform P in the downhill 102 at the uppermost position PH slides down on the main slide surface 84 in an inverted posture. The restraining member 98 allows the preform P in the inverted posture to move. The preform P leaves the downhill 102 in an inverted posture. Inversion of the preform P is completed.

  In the reversing unit 46, the axis of the rotating body 52 is installed at a position higher in the direction of gravity on the first end 52a side than on the second end 52b side. In such a reversing unit 46, the preform P can slide down on the main slide surface 84 and the first and second auxiliary slide surfaces 88 and 89 by the action of gravity. The preform P can be introduced into the individual downways 102 and discharged from the downways 102 without application of a special driving force.

  As described above, a plurality of downhill paths 102 are arranged in the circumferential direction of the rotating body 52. Accordingly, the preform P can be introduced into the downhill 102 at every small rotation angle such as a rotation angle of 60 degrees, and at the same time, the preform P can exit from the downhill 102. For example, the inversion processing time can be shortened as compared with the case where only one downhill 102 is formed on the rotating body 52. As the number of downhills 102 increases, the inversion processing time is shortened.

  Moreover, as described above, the distance S between the first end 52 a of the rotating body 52 and the inner edge of the restraining member 98 is set to a size that holds the three preforms P in one row in the downhill 102. . Since the three preforms P are reversed at a time, the reversal processing time can be significantly shortened as compared with the case where only one preform P is held in each downhill 102. .

  If a sufficient number of preforms P are not supplied to the outlet end 56 of the second slide conveyor 47, the leading preform P cannot receive sufficient self-weight, that is, propulsive force from the subsequent preform P. The preform P cannot be delivered to the preform delivery device 21 until a sufficient number of preforms P are accumulated at the outlet end 56. As a result, supply failure may occur in the crystallization apparatus 12. The regulation mechanism 113 is used to avoid such supply failure. A detection device (sensor) and a flow rate monitoring device (sensor) are disposed on the second slide conveyor 47. The detection device monitors whether or not the number of preforms P that can ensure a minimum propulsive force is accumulated at the outlet end 56. The flow rate monitoring device monitors the accumulation state of the preform P in the vicinity of the inlet end 55. If the preform P arranged on the second slide conveyor 47 is insufficiently supplied as a result of the preform P being returned to the upstream side by the rotary blade 67 of the preform aligning device 39 or being discharged out of the device, the regulation will occur. The regulating member 115 of the mechanism 113 is positioned at the first position. In the first slide conveyor 45, the advance of the leading preform P is blocked. A new preform P is prevented from entering toward the lowermost downhill 102. At this time, the rotating body 52 rotates intermittently at a higher speed than normal. As a result, the preform P is discharged from the downhill 102 at the uppermost position PH. Prior to the operation of the regulating mechanism 113, the three rows of preforms P accumulated in the reversing unit 46 slide off the reversing unit 46 every rotation of 60 degrees. In this way, at the exit end 56 of the second slide conveyor 47, at least nine preforms P form a line in accordance with the inclination of the slide surface 54. The leading preform P is pushed out toward the preform delivery device 21 by the function of the weight of the preform P. Even when supply shortage occurs on the second slide conveyor 47 in this way, the light supply shortage is solved by forming a row of at least nine preforms P. Stable supply of the crystallization apparatus 12 becomes possible.

  The main slide surface 84 does not necessarily have to extend in parallel with the axis of the rotation shaft 53. For example, the rotating body 52 may be formed in a truncated cone shape. According to such a shape, the preform P can slide down in the downhill 102 at different downhill speeds when the preform P is introduced and when the preform P exits. The first edge 88 a and the second edge 89 a do not necessarily have to extend parallel to the axis of the rotation shaft 53. The first edge 88a and the second edge 89a are not necessarily continuous straight lines. That is, the first edge 88a and the second edge 89a may be curved or may be interrupted as long as the guidance of the preform P that slides down in the downhill path 102 is not hindered. The first auxiliary slide surface 88 and the second auxiliary slide surface 89 need not necessarily extend parallel to the main slide surface 84. That is, the first auxiliary slide surface 88 and the second auxiliary slide surface 89 may be inclined or curved with respect to the main slide surface 84 as long as the preform P slides down smoothly in the downhill path 102. The main slide surface 84 is not necessarily flat. That is, the main slide surface 84 may be curved or may be interrupted as long as the preform P slides down smoothly in the downhill 102.

  Note that a blow molding machine may be incorporated in the preform handling device 11 instead of the crystallization device 12 described above.
