The false twisting machine 1 is, for example, for applying a twist to thermoplastic synthetic fibers such as polyester and polyamide to impart shrinkage to produce a processed yarn rich in elasticity.

  As shown in FIG. 1, the false twisting machine 1 includes a main machine base 2, two winding bases 3, a support portion 4, and the like, and each device described later is disposed thereon. The main machine base 2 extends in the depth direction of the paper surface. The two take-up tables 3 are arranged opposite to the main machine base 2 with a work space 6 at symmetrical positions around the main machine base 2. On the side opposite to the work space 6 of the take-up stand 3, there is a space 7 in which the operator picks up a fully wound package P that has been taken up by a take-up device 13 provided later on the take-up stand 3. To do. The support unit 4 connects the main machine base 2 and the two winding stands 3.

  The false twisting machine 1 includes two yarn feeding creels 11 (yarn feeding portions) disposed opposite to the two winding stands 3 with the space 7 interposed therebetween, and two false twisting devices provided on the upper part of the main machine stand 2. 12, winding devices 13 provided on the two winding tables 3, respectively. The yarn feeding creel 11 holds the yarn feeding package S and feeds the yarn Y of the yarn feeding package S. The false twisting device 12 false twists the yarn Y supplied from the yarn feeding creel 11. The winding device 13 winds the yarn Y falsely twisted by the false twisting device 12 to form a package P. Details of the winding device 13 will be described later.

  In the yarn path from the yarn feeding creel 11 to the winding device 13, a first feed roller 14, a first heating device 17, a cooling device 19, a false twisting device 12, a second feed roller 15, A second heating device 18 and a third feed roller 16 are arranged. In the false twisting machine 1, devices along the yarn path from the yarn feeding creel 11 to the winding device 13 are arranged symmetrically across the main machine base 2.

  The first feed roller 14 is disposed at the upper end portion of the winding table 3. The first heating device 17 is disposed above the work space 6. The cooling device 19 is disposed closer to the main machine base 2 than the first heating device 17 above the work space 6. The second feed roller 15 is disposed below the false twisting device 12 of the main machine base 2. The second heating device 18 is disposed below the second feed roller 15 of the main machine base 2. The first heating device 17 and the cooling device 19 are arranged substantially linearly along the horizontal direction above the work space 6, and the yarn path from the yarn feeding creel 11 to the winding device 13 is the work space 6.

The winding roller 23 frictionally contacts the package P that is winding the yarn Y and rotates it. The pair of doffing arms 24 is for doffing (moving) the full package P to the stocker 25. The pair of doffing arms 24 is provided at a predetermined interval in the depth direction of the paper, and the package P is sandwiched between upper end portions. Each of the pair of doffing arms 24 is rotatable around the lower end. The pair of doffing arms 24 are rotated counterclockwise from the position shown in FIG. 2, whereby the fully packaged package P is doffed to the stocker 25.

  The stocker 25 stores the full package P. In the present embodiment, the stocker 25 can store two packages P. The stocker 25 has a pair of guide rails 27 extending in a substantially horizontal direction. The pair of guide rails 27 are provided at a predetermined interval in the depth direction of the paper, and are inclined downward toward the space 7. Therefore, in the package P doffed to the stocker 25 by the doffing arm 24, both ends of the paper tube B roll on the pair of guide rails 27 and move to the space 7 side.

  The first restricting mechanism 50 restricts movement of the package P (first package P) located closest to the space 7 toward the space 7 (movement to a package receiver 52 described later located at the receiving position). In addition, the movement restriction of the package P toward the space 7 (movement restriction to a package receiver 52 described later located at the receiving position) is released. The first restriction mechanism 50 includes a pair of restriction members 26 and an air cylinder 74 (see FIG. 6) that drives the pair of restriction members 26. Each of the pair of regulating members 26 is rotatably provided on the guide rail 27. Each of the pair of regulating members 26 has a claw 28 that protrudes upward and comes into contact with the paper tube B of the package P on the guide rail 27. The pair of restricting members 26 rotate in the counterclockwise direction from the restricting position (position shown in FIG. 2) where the pawl 28 abuts the paper tube B and restricts the movement of the package P and the restricting position shown in FIG. Then, the air cylinder 74 is rotated by driving the air cylinder 74 between the release position where the pawl 28 moves downward and does not come into contact with the paper tube B and the movement restriction of the package P is released. The second restricting mechanism 40 moves the package P (second package P) positioned next to the space 7 next to the first package P to the space 7 side (the first package P is positioned). The movement of the second package P to the space 7 side (the movement restriction to the position where the first package P is located) is released.

  The winding device 13 winds the yarn Y by rotating the paper tube B (package P) held by the cradle 22 by the winding roller 23 while traversing the yarn Y by a traverse device (not shown). Although not shown, the winding device 13 includes a yarn cutting mechanism that cuts the yarn Y connected to the package P doffed by the stocker 25, an air sucker that sucks and holds the cut yarn end, and a paper tube B that is a cradle.

  In the winding device 13 described above, the processes from the supply of the paper tube B to the cradle 22 to the winding of the yarn Y to the paper tube B and the doffing to the stocker 25 of the full package P are automated. Has been. When the timer count reaches a predetermined count, the winding device 13 automatically dries the fully wound package P from the cradle 22 to the stocker 25 by the doffing arm 24. At this time, the yarn Y connected to the package P is cut by the yarn cutting mechanism. Next, the paper tube B is supplied from the paper tube holder 21 to the cradle 22 through the paper tube supply mechanism. Then, the yarn Y is hung on the paper tube B supplied to the cradle 22 by the yarn hooking mechanism, and winding of the yarn Y onto the paper tube B is started.

  In order to produce the package P efficiently, the false twisting machine 1 of this embodiment is provided with four stages of winding devices 13 in the vertical direction. As a result, the package P can be efficiently produced. However, the winding device 13 in the fourth stage (uppermost stage) from the bottom has a height of about 2 m or more (for example, about 2.3 m) from the floor surface. Located in. In the conventional false twisting machine, the operator collects the package formed by the fourth-stage winding device from the bottom on the gantry, etc., but prepares the gantry and collects the package. The work is inefficient. Therefore, the false twisting machine 1 of the present embodiment includes a lowering device 51 (see FIG. 3 and the like) for lowering the package P formed by the winding device 13 provided in the fourth stage from the bottom.

  FIG. 3 is a schematic front view showing the lowering device 51 and the like. FIG. 4 is a schematic front view showing the lowering device 51 and the like in a state where the package P is lowered. FIG. 5 is a schematic perspective view showing the lowering device 51 and the like. As shown in FIGS. 3 to 5, the lowering device 51 includes a package receiver 52 and an elevating mechanism 53.

  The package receiver 52 receives the package P formed by the winding device 13. The package receivers 52 correspond to the four winding devices 13 provided in the depth direction of the paper surface in FIG. 1 and FIG. 2 (the width direction of the winding table 3), and four package receivers 52 are provided side by side in the width direction of the winding table 3. ing. Further, the package receiver 52 has a substantially U-shape with an upper opening, and receives the package P at the opening. On the upper end of the side wall 57 extending upward from the bottom surface 56 of the package receiver 52, a protrusion (not shown) that comes into contact with the end portion of the paper tube B of the package P is provided. As shown in FIG. 4, the protrusion prevents the package P from dropping from the package receiver 52 when the package receiver 52 is inclined. 3 to 5 show a state in which the package P is located in the package receiver 52.

  The elevating mechanism 53 includes a receiving position adjacent to the winding device 13 (position of the package receiver 52 shown in FIG. 3) and a collection position below the receiving position (position of the package receiver 52 shown in FIG. 4). ) And between them. In the present embodiment, the receiving position is a position adjacent to the winding device 13 provided at the fourth level (uppermost level) from the bottom. The collection position is a position at which the operator collects the package P, and is substantially the same height as the winding device 13 provided at the third level from the bottom (directly below the winding device 13 provided at the top level). Is the position.

  The elevating mechanism 53 includes a link 54 and an air cylinder 55. The link 54 includes a pair of arms 59 each having one end attached to a frame 58 provided on both sides in the width direction of the winding table 3, and a connecting bar 60 that connects the other ends of the pair of arms 59. Have. One end of each of the pair of arms 59 is rotatable with respect to the frame 58. The connecting bar 60 extends in the width direction of the winding table 3. By being connected to the connecting bar 60, the rotation of the pair of arms 59 is synchronized. The package receiver 52 is attached to the connecting bar 60. Further, one end portion (rod 62 described later) of the air cylinder 55 is rotatably attached to the connecting bar 60. Each of the pair of arms 59 is provided with a rotation restricting member (not shown) that restricts the rotation of the arm 59 in the counterclockwise direction from the state shown in FIG.

  The air cylinder 55 has a tube 61 and a rod 62. The other end portion (tube 61) of the air cylinder 55 is attached to the substantially center of a support member 63 that extends in the width direction at the upper end of the winding table 3. The air cylinder 55 extends substantially in the vertical direction. When air is supplied into the tube 61, the rod 62 comes out of the tube 61 and extends downward (state shown in FIG. 4). In addition, when the air in the tube 61 is exhausted, the rod 62 enters the tube 61 and contracts upward (the state shown in FIG. 3).

  When the air cylinder 55 is driven from the state shown in FIG. 3 and the air cylinder 55 is extended, the link 54 to which the air cylinder 55 is rotatably connected is centered on the take-up stand 3 (frame 58) side. It rotates counterclockwise at. Accordingly, the package receiver 52 attached to the link 54 rotates counterclockwise together with the link 54 from the receiving position shown in FIG. 3 and moves downward. Then, with the air cylinder 55 fully extended, the package receiver 52 is located at the collection position shown in FIG. At the collection position, the package receiver 52 is in a state where the space 7 side is inclined downward.

  When the air cylinder 55 is driven from the state shown in FIG. 4 and the air cylinder 55 contracts, the link 54 to which the air cylinder 55 is pivotally connected is centered on the take-up stand 3 (frame 58) side. It rotates in the clockwise direction. Therefore, the package receiver 52 attached to the link 54 rotates clockwise together with the link 54 from the collection position shown in FIG. Then, with the air cylinder 55 fully contracted, the package receiver 52 is located at the receiving position shown in FIG.

  FIG. 6 is a block diagram schematically showing an electrical configuration of a control device and the like included in the false twisting machine 1. As shown in FIG. 6, the false twisting machine 1 controls the first regulating mechanism 50 (air cylinder 74), the lowering device 51 (air cylinder 55), the lamp 72 (notification means), and controls one operation button 73. A control device 71 that receives an operation is provided. The operation button 73 is for an operator to operate the first restriction mechanism 50 and the lowering device 51. As shown in FIGS. 3 and 4, the operation button 73 is provided below the third winding device 13 from the bottom. The operation of the operation button 73 is accepted by the control device 71. The lamp 72 is, for example, an LED lamp, and notifies the worker of the state of the false twisting machine 1 by blinking or lighting. The lamp 72 is provided below the operation button 73 as shown in FIGS.

  The first restriction mechanism 50 is controlled by the control device 71 and restricts the movement of the package P to the receiving position when the package receiver 52 is not positioned at the receiving position, and the package receiver 52 is positioned at the receiving position. Then, the restriction on the movement of the package P to the receiving position is released. That is, when the package receiver 52 is not positioned at the receiving position, the pair of restricting members 26 is positioned at the restricting position by the air cylinder 74, and when the package receiver 52 is positioned at the receiving position, the pair of restricting members is detected by the air cylinder 74. 26 is located at the release position.

  Next, the operation of the false twisting machine 1 when the package P is lowered by the lowering device 51 will be described. FIG. 7 shows a state where there is no package P in the package receiver 52 located at the receiving position. When the operation button 73 is operated in the state shown in FIG. 7, that is, when the package receiver 52 is located at the receiving position (first button operation), the control device 71 causes the first restricting mechanism 50 to Release the restriction on movement to the receiving position. When the package receiver 52 is not located at the receiving position, the control device 71 does not accept the operation of the operation button 73, that is, ignores the operation of the operation button 73, and the package P is moved to the receiving position by the first restriction mechanism 50. Do not release movement restrictions. Further, the control device 71 detects whether or not the package receiver 52 is in the receiving position, that is, whether or not the air cylinder 55 is fully contracted by a sensor switch (not shown) attached to the air cylinder 55. Deciding. The control device 71 determines that the package receiver 52 is in the receiving position when the air cylinder 55 is fully contracted. When the movement restriction of the package P to the receiving position by the first restricting mechanism 50 is released, the package P rolls on the guide rail 27 toward the package receiver 52 located at the receiving position, as shown in FIG. , Received by the package receiver 52. The first package P rolls, but the second package P stored in the stocker 25 is configured to remain in its original position and not move by the second moving mechanism 40. .

  When the operation button 73 is operated after the package P has moved to the package receiver 52 (second button operation), the control device 71 operates a rotation restricting member (not shown) to restrict the rotation of the arm 59. Is released, the air cylinder 55 is driven to rotate the arm 59, and the package receiver 52 is moved (lowered) from the receiving position to the collection position by the lifting mechanism 53 (state shown in FIG. 4). The control device 71 flashes the lamp 72 while the package receiver 52 is being lowered by the elevating mechanism 53, that is, while the air cylinder 71 is being driven, to notify that the package receiver 52 is being lowered. The control device 71 does not accept the operation of the operation button 73 while the package receiver 52 is lowered by the elevating mechanism 53, that is, while the air cylinder 55 is being driven. That is, the control device 71 ignores the operation of the operation button 73 even if the operation button 73 is operated. In the present embodiment, the lowering device 51 causes the package P formed by the winding device 13 provided at the fourth level from the bottom to be approximately the same height as the winding device 13 provided at the third level from the bottom. It has been lowered.

  When the package receiver 52 moves to the collection position, the operator can collect the package P from the package receiver 52 located at the collection position in the space 7. At this position, the movement restriction of the second package P by the second restriction mechanism 40 is released by a signal from the control device 71, so that the second package P rolls toward the space 7. At this time, the movement of the package P toward the space 7 is restricted and stopped by the first restricting mechanism 50, and prepares for the next lowering operation of the package P (state shown in FIG. 8). When the operation button 73 is operated after the first package P is collected from the package receiver 52 by the operator (third button operation), the control device 71 drives the air cylinder 55 to move the arm 59. The package receiver 52 is moved (lifted) from the collection position to the receiving position by the lifting mechanism 53 (state shown in FIG. 7). While the package receiver 52 is being lifted by the lifting mechanism 53, that is, while the air cylinder 55 is being driven, the control device 71 blinks the lamp 72 to notify that the package receiver 52 is being lifted. Further, the control device 71 does not accept the operation of the operation button 73 while the package receiver 52 is raised by the elevating mechanism 53, that is, while the air cylinder 55 is being driven. That is, the control device 71 ignores the operation of the operation button 73 even if the operation button 73 is operated. In addition, the control device 71 detects whether or not the package receiver 52 is in the collection position, that is, whether or not the air cylinder 55 is fully extended by a sensor switch (not shown) attached to the air cylinder 55. Deciding. The control device 71 determines that the package receiver 52 is in the collection position when the air cylinder 55 is fully extended.

  In the false twisting machine 1 described above, the lowering device 51 is the package formed by the winding device 13 provided in the uppermost stage, that is, the fourth stage from the bottom among the winding devices 13 provided in four stages. Lower P down. Therefore, since the operator can easily collect the package P that has been lowered, the efficiency of collecting the package P by the operator is improved.

  Further, the elevating mechanism 53 of the lowering device 51 moves the package receiver 52 into a receiving position adjacent to the winding device 13 (the position of the package receiver 52 shown in FIG. 3) and a collection position below the receiving position (see FIG. 4). The position of the package receiver 52 shown in FIG. Therefore, the operator can easily collect the package P that has been moved (lowered) to the collection position below the receiving position.

  The first restricting mechanism 50 restricts the movement of the package P to the receiving position when the package receiver 52 is not positioned at the receiving position, and the package to the receiving position when the package receiver 52 is positioned at the receiving position. Release the P movement restriction. Therefore, when the package receiver 52 is not located at the receiving position, the package P is not moved to the receiving position, so that the package is prevented from being accidentally dropped from the winding device 13.

  In addition, when the package receiver 52 is located at the receiving position, the first restricting mechanism 50 releases the restriction on movement of the package P to the receiving position by operating the operation button 73. In addition, the lifting mechanism 53 moves the package receiver 52 from the receiving position to the collection position by operating the operation button 73 after the package P has moved to the package receiver 52.
