Hereinafter, embodiments of the invention will be described. Fig. 1 is a schematic front view showing the false twisting machine of the present embodiment. In the false twisting machine 1, for example, a thermoplastic synthetic fiber such as polyester or polyamide is applied with a false twist to impart curl (wrinkle) to produce a processed yarn having excellent stretchability.

As shown in Fig. 1, the false twist processing machine 1 has a mainframe 2. Two winding tables 3, a support portion 4, and the like, and each of the devices described later is disposed. The main table 2 extends in the depth direction of the paper. The two winding tables 3 are arranged symmetrically with respect to the main table 2 with the working space 6 interposed therebetween. On the side opposite to the work space 6 of the take-up table 3, there is a space 7 for the worker to pick up the full package P picked up by the take-up device 13 which will be described later, which is provided in the take-up table 3. The support portion 4 connects the main table 2 and the two winding tables 3.

The false twisting machine 1 includes two yarn supplying bobbins 11 (gauze portions) that are disposed to face each other and are disposed to face the two winding tables 3, and are provided on the upper portion of the main table 2. Two false twisting devices 12, a winding device 13 provided in each of the two winding tables 3, and the like. The yarn bobbin 11 is fed to the yarn package S, and the yarn Y of the yarn package S is fed to the yarn. The false twisting device 12 is a yarn Y that is to be supplied from the yarn bobbin 11 to be false. The winding device 13 is obtained by winding up the yarn Y which is falsely twisted by the false twisting device 12 to form a package P. The details of the winding device 13 will be described later.

In the yarn path from the yarn supplying bobbin 11 to the winding device 13, the first paper feed roller 14, the first heating device 17, the cooling device 19, and the false twisting device 12 are disposed in order from the upstream of the yarn running direction. The second paper feed roller 15, the second heating device 18, and the third paper feed roller 16. In the false twisting machine 1, each of the devices along the yarn path from the yarn supplying bobbin 11 to the winding device 13 is symmetrically arranged to be held symmetrically by the main table 2.

The first paper 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 the first one placed above the work space 6. The heat unit 17 is on the side of the main unit 2 side. The second paper feed roller 15 is disposed below the false twisting device 12 of the main table 2. The second heating device 18 is disposed below the second paper feed roller 15 of the main table 2. Further, the first heating device 17 and the cooling device 19 are arranged almost vertically in the horizontal direction above the working space 6, and the yarn path from the yarn supplying bobbin 11 to the winding device 13 surrounds the working space 6. Ground formation. The first heating device 17 and the cooling device 19 are connected to the support portion 4 and fixed in position. The operator is a work vehicle for hanging yarns (not shown) in the work space 6, and can perform yarn hanging at a higher position in the vicinity of the first heating device 17 or the cooling device 19 or perform maintenance.

The first to third paper feed rollers 14 to 16 are rollers for conveying the yarn Y from the upstream side in the yarn running direction to the downstream side. The yarn feed speed of the second paper feed roller 15 is set to be faster than the yarn feed speed of the first paper feed roller 14, and the yarn feed speed is set. Therefore, the yarn Y extends between the first paper feed roller 14 and the second paper feed roller 15. The yarn feed speed is set such that the yarn feed speed of the third paper feed roller 16 is slower than the yarn feed speed of the second paper feed roller 15. Therefore, between the second paper feed roller 15 and the third paper feed roller 16, the yarn Y is subjected to a relaxation heat treatment.

Here, the operation of the false twisting machine 1 until the yarn Y to which the yarn is fed from the yarn bobbin 11 is taken up by the winding device 13 will be described. The yarn Y extending between the first paper feed roller 14 and the second paper feed roller 15 is twisted by the false twisting device 12. The false twisting device 12 is, for example, a belt type jaw-type false twisting machine that holds the yarn Y between the pair of belts that cross each other, and applies the twisting and feeding to the yarn Y. Crepe formed by the false twist device 12 The yarn Y that has propagated to the first paper feed roller 14 and is stretched and twisted is thermally fixed by the first heating device 17, and then cooled by the cooling device 19. The twisted and heat-fixed yarn Y is untwisted until the second paper feed roller 15 passes through the false twisting device 12. The yarn Y which has been subjected to the false twist processing is tempered by the second heating device 18, and is taken up by the winding device 13 in the paper tube B (see Fig. 2) to form the package P.

Next, the winding device 13 will be described in detail. As shown in Fig. 1, the winding device 13 is provided in one winding unit 3, and each of them is arranged in four stages in the vertical direction, that is, in the vertical direction. Further, the winding device 13 is provided in four in the paper surface depth direction (the width direction of the winding table 3). Therefore, each of the four winding devices 13 is provided with four segments. In other words, the winding device 13 is provided with a total of 16 (4 segments × 4) winding devices 13 in one winding table 3. The height of the winding device 13 is, for example, the winding device 13 provided in the fourth lower stage is about 2.3 m from the ground (the height a shown in Fig. 3), and is provided in the winding device 13 from the lower third stage. It is about 1.8 m from the ground (the height b shown in Fig. 3), and the winding device 13 provided in the lower second stage is about 1.3 m from the ground (the height c shown in Fig. 3), and is set at the lowermost section. The winding device 13 is about 0.8 m from the ground (the height d shown in Fig. 3).

Fig. 2 is an enlarged view of the winding device 13 in Fig. 1. Further, since the winding device 13 is located inside the winding table 3, a part thereof is not visible from the winding table 3, but in the first drawing, a portion which is not visible from the winding table 3 is also illustrated. Further, in the second drawing, the illustration of the winding table 3 is omitted. As shown in Fig. 2, the winding device 13 includes a paper tube holder 21, a bracket 22, a take-up roller 23, a pair of unloading arms 24, and storage. The library 25, the first restriction mechanism 50 (restriction mechanism), the second restriction mechanism 40, and the like.

The paper tube holder 21 is a person who accumulates the paper tube B. The bracket 22 is a package P that holds the yarn Y in the winding. The take-up roller 23 is rotated in frictional contact with the package P in which the yarn Y is wound up. The pair of unloading arms 24 are those in which the package P that has been fully wound is unloaded (moved) toward the storage 25 . The pair of unloading arms 24 are provided at predetermined intervals in the depth direction of the paper surface, and the package P is held by the end portions on the upper side. Further, the pair of unloading arms 24 are each rotatable about the end portion on the lower side. From the position shown in Fig. 2, by rotating the pair of unloading arms 24 in the counterclockwise direction, the package P which is full is unloaded toward the storage 25.

The storage 25 is a package P holder that will become a full roll. In the present embodiment, the storage 25 is such that two packages P can be stored. The storage 25 is a pair of guide rails 27 that extend substantially in the horizontal direction. The pair of guide rails 27 are provided at predetermined intervals in the depth direction of the paper surface, and are inclined downward toward the space 7. Therefore, the package P which is unloaded by the unloading arm 24 toward the storage 25 is such that both ends of the paper tube B are rotated on the pair of guide rails 27 and moved toward the space 7 side.

The first restricting mechanism 50 restricts the movement of the package P (the first package P) located at the position closest to the space 7 toward the space 7 (movement toward the package receiving member 52, which will be described later, at the receiving position). In addition, the movement restriction on the space 7 side of the package P (the movement restriction of the package receiving member 52 to be described later at the receiving position) is released. The first restricting mechanism 50 includes a pair of restricting members 26 and a pneumatic cylinder 74 that drives the pair of restricting members 26 (see FIG. 6). a pair of restricting members 26 are rotatably provided On the guide rail 27. Further, the pair of restricting members 26 each have a claw 28 that protrudes upward and abuts against the paper tube B of the package P on the guide rail 27. The pair of restricting members 26 are driven by the pneumatic cylinder 74, and the claw 28 is in contact with the paper tube B to restrict the movement of the package P (the position shown in Fig. 2), and from the second figure. The illustrated restriction position is rotated in the counterclockwise direction to move the claw 28 downward, and does not rotate in contact with the paper tube B to release the movement restriction of the package P. The second restriction mechanism 40 restricts the movement toward the space 7 of the package P (second package P) located at the position close to the space 7 of the first package P (movement toward the position where the first package P is located) In addition, the movement restriction on the space 7 side of the second package P (the movement restriction to the position where the first package P is located) is released.

The winding device 13 rotates the paper tube B (package P) held by the carrier 22 by the winding roller 23 while the yarn Y is traversed by a lateral device (not shown), and the yarn Y is rotated. Rolling. In addition, the winding device 13 further includes a yarn cutting mechanism that cuts the yarn Y connected to the package P that is unloaded in the storage 25, and a yarn end that is sucked and held. The air suction cup, the paper tube supply mechanism that supplies the paper tube B to the tray, the yarn hook mechanism that hooks the yarn Y to the paper tube B held by the tray 22, and the like.

In the winding device 13 described above, the supply of the paper tube B to the tray 22, the winding of the yarn Y to the paper tube B, and the unloading of the package P of the full package P are performed. The project is being automated. The winding device 13 automatically rotates the package P from the tray 22 toward the storage 25 by the unloading arm 24 when the count of the timer is a predetermined number. At this time, the yarn cutting mechanism is used to connect with the package P. Y yarn Y is cut. Next, the paper tube B is supplied from the paper tube holder 21 to the tray 22 through the paper tube supply mechanism. Further, the yarn Y is hung on the paper tube B supplied from the tray 22 by the yarn hooking mechanism, and the winding of the yarn Y toward the paper tube B is started.

In the false twisting machine 1 of the present embodiment, in order to efficiently produce the package P, the winding device 13 is set to four stages in the vertical direction. Thereby, the package P can be efficiently produced, but the winding device 13 from the lower fourth stage (the uppermost stage) is located at a height of about 2 m or more (for example, about 2.3 m) from the ground. In the conventional false twisting machine, the operator collects the package formed by the winding device of the fourth stage from the stand, etc., but the work of preparing the package for recovery of the package is inferior. Here, 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 of the lower fourth stage.

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 in which the package P is lowered downward. Fig. 5 is a schematic perspective view showing the descending device 51 and the like. As shown in FIGS. 3 to 5, the lowering device 51 has a package receiving member 52 and a lifting mechanism 53.

The package receiving member 52 is a package P receiver formed by the winding device 13. The package receiving member 52 is provided with four winding devices 13 corresponding to the paper surface depth direction (the width direction of the winding table 3) in the first and second drawings, and is oriented in the width direction of the winding table 3. Set 4 in parallel. Moreover, the package receiving member 52 is approximately the upper opening. In the shape of a word, the package P is accepted in the opening portion. A projection (not shown) that abuts against an end portion of the paper tube B of the package P is provided at an upper end of the side wall 57 that extends upward from the bottom surface 56 of the package receiving member 52. As a result of this projection, as shown in FIG. 4, the package P is not dropped from the package receiving member 52 in a state where the package receiving member 52 is inclined. In the third to fifth figures, the state in which the package P is positioned in the package receiving member 52 is shown.

The elevating mechanism 53 is a take-up position of the package receiving member 52 adjacent to the winding device 13 (the position of the package receiving member 52 shown in Fig. 3) and a recovery position lower than the receiving position. The person moves between (the position of the package receiving member 52 shown in Fig. 4). In the present embodiment, the receiving position is located adjacent to the winding device 13 provided from the lower fourth stage (uppermost stage). In addition, the collection position is a position at which the operator collects the package P, and is located at the same height as the winding device 13 provided in the lower third stage (directly below the winding unit 13 in the uppermost stage).

The elevating mechanism 53 has a link 54 and a pneumatic cylinder 55. The link 54 is a frame 58 provided on both sides in the width direction of the winding table 3, and has a pair of arms 59 that are attached to the one end, and a pair of arms that connect the other ends of the pair of arms 59. Connecting rod 60. The pair of arms 59 are such that one end portion can be rotated about the frame 58 individually. The connecting rod 60 extends in the width direction of the winding table 3. By the connection with the connecting rod 60, the rotation of the pair of arms 59 is synchronized. Further, the package receiving member 52 is attached to the connecting rod 60. Further, one end portion (a rod 62 to be described later) of the pneumatic cylinder 55 is rotatably attached to the connecting rod 60. Further, each of the pair of arms 59 is provided with a rotation for restricting the counterclockwise direction from the state shown in Fig. 3 to the arm 59. Rotation restricting member (not shown).

The pneumatic cylinder 55 has a tube 61 and a rod 62. The other end portion (tube 61) of the pneumatic cylinder 55 is attached to the upper end of the winding table 3 at substantially the center of the support member 63 extending in the width direction. The pneumatic cylinder 55 extends substantially in the vertical direction, and by supplying air into the tube 61, the rod 62 protrudes from the tube 61 and is extended downward (state shown in Fig. 4). Further, in the pneumatic cylinder 55, the air in the tube 61 is exhausted, and the rod 62 is introduced into the tube 61 to be contracted upward (the state shown in Fig. 3).

The pneumatic cylinder 55 is driven from the state shown in Fig. 3, and if the pneumatic cylinder 55 is extended, the link 54 that rotatably connects the pneumatic cylinder 55 is on the side of the winding table 3 (frame 58). Turn counterclockwise in Figure 3. Therefore, the package receiving member 52 attached to the link 54 is rotated from the link 54 in the counterclockwise direction from the receiving position shown in FIG. 3, and moves downward. Further, in a state in which the pneumatic cylinder 55 is extended to the bottom, the package receiving member 52 is located at the recovery position shown in FIG. In the collection position, the package receiving member 52 is in a state of being inclined downward toward the space 7 side.

The pneumatic cylinder 55 is driven from the state shown in Fig. 4, and if the pneumatic cylinder 55 is contracted, the link 54 that rotatably connects the pneumatic cylinder 55 is oriented on the side of the winding table 3 (frame 58). Turn clockwise in Figure 4. Therefore, the package receiving member 52 attached to the link 54 is rotated in the clockwise direction together with the link 54 from the recovery position shown in Fig. 4, and is moved upward. Further, in a state where the air cylinder 55 is contracted to the bottom, the package receiving member 52 is located at the receiving position shown in FIG.

Fig. 6 is a block diagram schematically showing an electrical arrangement of a control device or the like provided in the false twisting machine 1. As shown in Fig. 6, the false twisting machine 1 is provided with control of the first restricting mechanism 50 (pneumatic cylinder 74), the lowering device 51 (pneumatic cylinder 55), and the bulb 72 (information means) and receives one operation button 73. Control device 71 for operation. The operation button 73 is for the operator to operate the first restriction mechanism 50 and the lowering device 51. This operation button 73 is provided below the winding device 13 of the lower third stage as shown in FIGS. 3 and 4. The operation of the operation button 73 is accepted by the control device 71. The bulb 72 is, for example, an LED bulb, and the state of the false twisting machine 1 is notified to the operator by clicking and lighting. This bulb 72 is provided below the operation button 73 as shown in FIGS. 3 and 4.

The first restriction mechanism 50 described above is controlled by the control device 71. When the package receiving member 52 is not located at the receiving position, the movement of the package P toward the receiving position is restricted, and when the package receiving member 52 is at the receiving position. In the case of the case, the movement restriction of the package P toward the receiving position is released. That is, when the package receiving member 52 is not located at the receiving position, the pair of restricting members 26 are positioned at the restricting position by the pneumatic cylinder 74, and when the package receiving member 52 is at the receiving position, by the pneumatic cylinder 74 The pair of restricting members 26 are placed at the release position.

Next, the operation of the false twisting machine 1 in the case where the package P is lowered downward by the lowering device 51 will be described. Fig. 7 is a view showing a state in which the package receiving member 52 at the receiving position is not loaded with the package P. The state shown in Fig. 7, that is, the package receiving member 52 is located at the receiving position. In the case where the operation button 73 is operated (the first button operation), the control device 71 releases the movement restriction of the package P generated by the first restriction mechanism 50 toward the receiving position. When the package receiving member 52 is not located at the receiving position, the control device 71 does not accept the operation of the operation button 73, that is, the operation of the operation button 73 is ignored, and the receiving position by the first restricting mechanism 50 is not released. The movement limit of the package P. Further, the control device 71 determines whether or not the package receiving member 52 is located at the receiving position, that is, whether or not the pneumatic cylinder 55 is contracted to the bottom, and is detected by a sensor switch (not shown) attached to the pneumatic cylinder 55. The control device 71 determines that the package receiving member 52 is located in the receiving position when the pneumatic cylinder 55 is contracted to the bottom. When the movement restriction of the package P by the first restriction mechanism 50 to the receiving position is released, the package P is rotated on the guide rail 27 toward the package receiving member 52 at the receiving position, as shown in FIG. As shown, the package receiving member 52 is received. In addition, the first package P is rotated, but the second package P stored in the storage 25 is configured such that the second restriction mechanism 40 does not move while staying at the original position.

When the package P is moved to the package receiving member 52 and the operation button 73 is operated (the second button operation), the control device 71 activates the rotation restricting member (not shown) to release the rotation restriction of the arm 59. The air cylinder 55 is driven to rotate the arm 59, and the package receiving member 52 is moved (dropped) from the receiving position to the recovery position by the elevating mechanism 53 (the state shown in Fig. 4). The control device 71 stops the bulb 72 while the package receiving member 52 is lowered by the elevating mechanism 53, that is, while the pneumatic cylinder 55 is being driven, and notifies that the package receiving member 52 is descending. And, the control device 71 is in the volume While the loading member 52 is lowered by the elevating mechanism 53, that is, while the pneumatic cylinder 55 is being driven, the operation of the operation button 73 is not accepted. 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 lowers the package P formed by the winding device 13 from the lower fourth stage to substantially the same height as the winding device 13 provided in the lower third stage.

When the package receiving member 52 moves toward the recovery position, the operator can collect the package P from the package receiving member 52 located at the collection position in the space 7. At this position, the movement restriction of the second package P generated by the second restriction mechanism 40 is released in response to the signal from the control device 71, and the second package P is rotated toward the space 7 side. At this time, the first restriction mechanism 50 stops the movement of the package P toward the space 7 side, and prepares the lowering operation of the next package P (the state shown in FIG. 8). When the first package P is recovered from the package receiving member 52 by the operator and the operation button 73 is operated (the third button operation), the control device 71 drives the pneumatic cylinder 55 to rotate the arm 59. The package receiving member 52 is moved (raised) from the recovery position to the received position by the elevating mechanism 53 (the state shown in Fig. 7). The control device 71 stops the bulb 72 while the package receiving member 52 is raised by the elevating mechanism 53, that is, while the pneumatic cylinder 55 is being driven, and notifies that the package receiving member 52 is rising. Further, the control device 71 does not accept the operation button 73 while the package receiving member 52 is being raised by the elevating mechanism 53, that is, while the pneumatic 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. Moreover, the control device 71 is for the package bearing Whether or not the connector 52 is located in the recovery position, that is, whether the pneumatic cylinder 55 is extended to the bottom, is detected by a sensor switch (not shown) attached to the pneumatic cylinder 55. The control device 71 determines that the package receiving member 52 is located in the recovery position when the pneumatic cylinder 55 is extended to the bottom.

In the false twisting machine 1 described above, the lowering device 51 is a package P formed by the winding device 13 provided in the uppermost stage, that is, from the lower fourth stage, among the winding devices 13 provided in four stages. Lower below. Therefore, the operator can easily collect the package P that has been lowered toward the lower side, so that the collection efficiency of the package P by the operator can be improved.

Further, the elevating mechanism 53 of the lowering device 51 is a receiving position of the package receiving member 52 adjacent to the winding device 13 (the position of the package receiving member 52 shown in Fig. 3), and the ratio of the receiving position. The lower recovery position (the position of the package receiving member 52 shown in Fig. 4) moves between. Therefore, the operator can easily collect the package P that has been moved to the recovery position (down) lower than the received position.

Further, when the package receiving member 52 is not located at the receiving position, the first restricting mechanism 50 restricts the movement of the package P toward the receiving position, and when the package receiving member 52 is at the receiving position, it will be taken toward the receiving position. The movement restriction of the package P of the position is released. Therefore, when the package receiving member 52 is not located at the receiving position, since the package P does not move toward the receiving position, it is possible to prevent the package from being accidentally (accidentally) dropped from the winding device 13.

When the package receiving member 52 is located at the receiving position, the first restricting mechanism 50 is operated by the operation button 73 to release the movement restriction of the package P toward the receiving position. And the lifting mechanism 53 is a roll After the loading P is moved to the package receiving member 52, the operation of the button 73 is performed to move the package receiving member 52 from the receiving position toward the recovery position. Therefore, the operator can instruct the false twisting machine 1 to instruct the package P to be unloaded downward from the winding device 13 by operating one operation button 73.

Further, when the package receiving member 52 is not positioned at the receiving position, the control device 71 does not accept the operation of the operation button 73, and does not release the movement restriction of the package P toward the receiving position by the first restriction mechanism 50. That is, when the package receiving member 52 is not located at the receiving position, the operation of the operation button 73 is ignored. Therefore, when the package receiving member 52 is not located at the receiving position, it is possible to prevent the operation button 73 from being operated, erroneously (accidentally) the package P from moving toward the receiving position, and the package P falling from the winding device 13.

Further, the bulb 72 is lifted and lowered during the lifting and lowering of the package receiving member 52 by the elevating mechanism 53, and the package receiving member 52 is lifted and lowered. Therefore, the operator can confirm that the package receiving member is in the lifting operation.

Further, the winding device 13 is provided in four stages in the vertical direction, and the lowering device 51 lowers the package P formed by the winding device 13 provided in the uppermost stage (from the lower fourth stage) downward.
