  The first embodiment of the present invention will be described below.

  FIG. 1 is a side view of a yarn winding device (hereinafter referred to as a winding device) according to the present embodiment, and FIG. 2 is a plan view of FIG.

  The winding device 1 winds a fishing line L as a thread around a plurality of spools having the same dimensions as a bobbin winding member. In the present embodiment, there are three or more spools, and the illustration and description of the spools other than the two adjacent spools 101 and 103 are omitted.

  The spools 101 and 103 include cylindrical winding cores 101a and 103a around which the fishing line L is wound, and end plates 101b, 101c, 103b, and 103c provided in flanges at both ends in the axial direction of the winding cores 101a and 103a. And.

  In addition, thread engagement grooves 101d and 101e are formed by cutting out a part in the circumferential direction at the peripheral edge portions of the end plates 101b and 101c, and similarly at the peripheral edge portions of the end plates 103b and 103c. Yarn engagement grooves 103d and 103e are formed.

  The winding device 1 includes a motor 5 as a rotating machine, a moving table 7, and a pulley 8 as yarn feeding means.

  In the motor 5, the main body 5 a is supported on the base 3 of the winding device 1 with the drive shaft 5 b being horizontal. Hereinafter, the axial direction of the drive shaft 5b of the motor 5 is referred to as a drive shaft direction.

  The winding cores 101a and 103a of the spools 101 and 103 are fitted on the driving shaft 5b of the motor 5 coaxially with the driving shaft 5b. Here, the spools 101 and 103 are fixed to the drive shaft 5b so that the end plates 101c and 103b whose outer surfaces are adjacent to each other overlap the thread engaging grooves 101e and 103d. Thus, by driving the motor 5, the spools 101 and 103 are rotationally driven integrally with the drive shaft 5b.

  The movable table 7 is supported by the base 3 so as to be movable relative to the base 3 in the drive axis direction.

  The pulley 8 is pivotally supported on the movable base 7 in a direction parallel to the drive shaft direction, and is fed out of the fishing line L so that the fishing line L is wound around the winding cores 101a and 103a of the spools 101 and 103 that are rotationally driven. It moves in the direction of the drive shaft integrally with the moving table 7. Here, after the fishing line L is wound around the winding core 101a, the fishing line L is wound around the winding core 103a. In addition, let the position which the fishing line L which contacted the pulley 8 left | separated from the pulley 8 be a yarn delivery port of the yarn delivery means which concerns on this invention. Further, a storage spool (not shown) for supplying the stored fishing line L to the pulley 8 is supported by the base 3, and the pulley 8 draws the fishing line L from the storage spool so that the winding cores 101a, 101a, It is comprised so that it may pay out toward 103a.

  Here, the moving speed of the pulley 8 is set so that the fishing line L is wound around the winding core 101a of the spool 101 at a distance between adjacent portions (with the adjacent portions in contact with each other). Control. That is, the feeding angle α of the fishing line L with respect to the moving direction of the pulley 8 (the moving direction of the pulley shown in FIG. 2) is detected until the fishing line L is wound from one end of the winding core 101a to the other end. Then, the moving speed of the pulley 8 is controlled so that the feeding angle α is maintained at an acute angle near a predetermined value. The same applies to the case where the fishing line L is wound around the winding core 103a of the spool 103.

  In order to control the moving speed of the pulley 8, it is difficult to keep the diameter of the fishing line L constant from the start end to the end in terms of processing accuracy, and the pulley 8 is connected to the fishing line while the spools 101 and 103 rotate once. This is because there is a concern that the fishing line L cannot be wound with a close interval between adjacent portions in the control in which the distance L is moved by a constant distance substantially equal to the diameter of L.

  In the winding device 1, the fishing line L is wound up to the end of the winding core 101a and is pulled between the winding core 101a and the yarn feeding port of the pulley 8 (hereinafter, the fishing line L fed out of the pulley 8). Is contacted with the end plate 101b or the end plate 101c, the contact is detected. And the winding apparatus 1 performs control which reverses the moving direction of the movable stand 7 and the pulley 8, whenever the said contact is detected.

  As shown in FIG. 3, the winding device 1 further includes a yarn feeding position control means 30.

  The line feeding position control means 30 is configured to be able to control the movement of the movable table 7, and the winding device 1 detects the end of winding of the fishing line L around the core 101 a of the spool 101 and temporarily stops driving the motor 5. Then, the position of the moving base 7 in the direction of the drive shaft is controlled so that the yarn discharge port of the pulley 8 is positioned closer to the end plate 101c side of the spool 101 than the inner surface of the end plate 103b of the spool 103. is there. Here, for example, when it is detected that the cumulative number of windings of the fishing line L around the winding core 101a of the spool 101 has reached the number corresponding to the end, the end of winding of the fishing line L around the winding core 101a is detected.

  The winding device 1 further includes a fishing line urging mechanism 31 and a fishing line urging mechanism 47.

  The fishing line urging mechanism 31 includes an air cylinder 33, a rack 35, a stopper pin 37, a gear 41, an arm 43, and a pin member 45 as a first line urging means.

  The air cylinder 33 includes a main body 33a supported by the movable base 7, and a rod 33b that can protrude from the main body 33a in a horizontal direction perpendicular to the drive shaft direction.

  The rack 35 is attached to the tip of the rod 33b in a state in which teeth are arranged in the protruding and protruding direction of the rod 33b (the rod protruding and protruding direction shown in FIGS. 1 and 2), and moves integrally with the rod 33b by driving the air cylinder 33. It is like that.

  The stopper pin 37 regulates the protruding amount of the rod 33b from the main body 33a by coming into contact with the rack 35 when the rod 33b of the air cylinder 33 protrudes a predetermined length from the main body 33a.

  The gear 41 that meshes with the rack 35 is supported by the movable table 7 such that a gear shaft member 41a is rotatable about a vertical axis.

  One end of the arm 43 is fixed to the upper end surface of the gear shaft member 41a in a state of extending horizontally.

  The pin member 45 is attached to the other end portion of the arm 43 with its lower end portion extending in the vertical direction.

  The fishing line urging mechanism 31 operates as follows in a state in which the line feeding position control means 30 positions the line feeding outlet of the pulley 8 closer to the end plate 101c than the inner surface of the end plate 103b. That is, as shown in FIG. 4, when the air cylinder 33 is driven, the rack 35 moves until it abuts against the stopper pin 37, and the gear 41 engaged with the rack 35 rotates clockwise in FIG. 2 around the gear shaft member 41a. Rotate. The arm 43 and the pin member 45 are rotated around the gear shaft member 41a integrally with the gear 41. As a result, the pin member 45 comes into contact with the fishing line L fed out of the pulley 8. Thus, the pin member 45 is pushed and biased until the contact portion of the fishing line L with the pin member 45 is positioned on the winding core 103a side from the inner surface of the end plate 103b. That is, the fishing line L fed from the pulley 8 protrudes from the core 101a side to the core 103a side beyond the end plates 101c and 103b.

  The fishing line urging mechanism 47 includes a motor 49, arms 51 and 53, and a lever member 55 as a second line urging means.

  The main body 49a of the motor 49 is supported by the movable table 7, and the drive shaft 49b is parallel to the drive shaft direction.

  One end of the arm 51 is fixed to the drive shaft 49b, and is driven to rotate in a plane orthogonal to the drive shaft direction by driving the motor 49.

  The arm 53 extends in a direction parallel to the drive shaft direction, and one end thereof is fixed to the other end of the arm 51.

  The lever member 55 is fixed to the other end portion of the arm 53 in such a state that the lever member 55 extends from one end portion to the other end portion so as to move away from the drive shaft 49 b of the motor 49.

  The fishing line urging mechanism 47 operates as follows in a state in which the fishing line L fed from the pulley 8 protrudes toward the winding core 103a by the urging of the pin member 45 of the fishing line urging mechanism 31. That is, when the motor 49 is driven and the drive shaft 49b is rotationally driven, the driving force is transmitted in the order of the arm 51, the arm 53, and the lever member 55, and the arm is moved until the lever member 55 contacts the upper portion of the core 103a. Rotate around the drive shaft 49b of the motor 49 integrally with the motors 51 and 53. As a result, the lever member 55 biases the portion of the fishing line L that protrudes toward the core 103a from the contact position of the fishing line L with the pin member 45 toward the axis of the core 103a. To do. In this way, the crossing portion L1 that is a portion crossing the end plates 101c and 103b when viewed from the direction orthogonal to the drive axis direction of the fishing line L is relative to the peripheral end surfaces of the end plates 101c and 103b of the spools 101 and 103 that are rotationally driven. It is slidably pressed in the circumferential direction.

  As shown in FIG. 5, the winding device 1 further includes yarn winding preparation control means 57.

  The yarn winding preparation control means 57 is configured to be able to transmit a drive control signal to the motor 5, the air cylinder 33, and the motor 49, and performs the following control.

  That is, the driving of the motor 5 that has been temporarily stopped after the winding of the fishing line L around the winding core 101a is resumed in a state where the transverse section L1 is pressed against the peripheral end surfaces of the end plates 101c and 103b by the lever member 55. As a result, the transverse section L1 is slid in the circumferential direction with respect to the peripheral end surfaces of the end plates 101c and 103b, dropped into the thread engaging grooves 101e and 103d, and engaged with the thread engaging grooves 101e and 103d. Let Then, the spools 101 and 103 are further rotated to stop the driving of the air cylinder 33 at the rotational position where the crossing portion L1 is hooked on the rear end in the rotational direction of the yarn engaging groove 103d, and the rod 33b is moved to the main body 33a. Let them pull in. Thereafter, the motor 49 is driven in the direction opposite to that when the lever member 55 is brought into contact with the upper portion of the core 103a. As a result, the pin member 45 is retracted to the rotational position before the air cylinder 33 is driven, and the lever member 55 is retracted to the rotational position before contacting the upper portion of the core 103a.

  As a result, the urging of the fishing line L by the pin member 45 is released, and the urging of the fishing line L by the lever member 55 is released, so that the fishing line L fed out of the pulley 8 is upstream of the cross-cut portion L1 (the above-described line feeding). The outlet side is urged into contact with the inner surface of the end plate 103b. In this way, preparation for winding the fishing line L around the winding core 103a of the spool 103 is performed.

  The yarn winding preparation control means 57 may stop the driving of the air cylinder 33 after driving the motor 49 in the reverse direction.

  Hereinafter, the operation of this embodiment will be described.

  After finishing the winding of the fishing line L around the winding core 101a of the spool 101, the motor 5 stops the rotational driving of the spools 101 and 103. FIG. 6A shows a state in which the winding of the fishing line L is finished at an intermediate position in the axial direction of the winding core 101a, and FIG. 7A shows a state in which FIG. 6A is viewed from the driving shaft direction. Indicates.

  Next, as shown in FIG. 6 (b), the yarn feeding position control means 30 controls the position of the movable table 7 in the drive shaft direction so that the yarn feeding outlet of the pulley 8 is connected to the end plate 103 b of the spool 103. The inner surface of the spool 101 is positioned closer to the end plate 101c. FIG. 6B illustrates a state where the yarn discharge port of the pulley 8 is in the same position as the end plate 101c or the end plate 103b in the drive shaft direction.

  Thereafter, as shown in FIGS. 4 and 6C, the air cylinder 33 is driven, the rack 35 is moved, the gear 41 engaged with the rack 35 is rotated, and the arm 43 is integrated with the gear 41. And the pin member 45 rotate. As a result, the pin member 45 is pushed and urged against the fishing line L fed out of the pulley 8. Thus, the fishing line L fed out of the pulley 8 protrudes from the core 101a side to the core 103a side over the end plates 101c and 103b.

  Further, the motor 49 is driven, and the driving force is transmitted in the order of the arm 51, the arm 53, and the lever member 55. As shown in FIG. 6D, the lever member 55 is centered on the drive shaft 49b of the motor 49. To rotate and come into contact with the upper part of the core 103a. As a result, the portion of the fishing line L that protrudes toward the winding core 103a is urged by the lever member 55 in a direction approaching the axis of the winding core 103a, and the transverse cut portion L1 of the fishing line L is the peripheral end surface of the end plates 101c and 103b. Is pressed against.

  Thereafter, the yarn winding preparation control means 57 resumes driving of the motor 5 and resumes rotational driving of the spools 101 and 103. As a result, the transverse section L1 slides in the circumferential direction with respect to the peripheral end surfaces of the end plates 101c and 103b of the spools 101 and 103, and as shown in FIGS. 6 (e) and 7 (b) It falls into the mating grooves 101e and 103d and engages with the thread engaging grooves 101e and 103d.

  Further, the yarn winding preparation control means 57 further rotates the spools 101 and 103, and stops the driving of the air cylinder 33 at the rotational position where the transverse cut portion L1 is hooked at the rear end in the rotational direction of the yarn engaging groove 103d. Let Thus, the biasing of the pin member 45 against the fishing line L is released, and then the motor 49 is driven in the reverse direction to release the biasing of the lever member 55 against the fishing line L. 6 (f) and FIG. 7 (c), the fishing line L comes into urging contact with the inner side surface of the end plate 103b of the spool 103 to be rotated, and the fishing line L against the winding core 103a of the spool 103 Preparation for winding is performed.

  In this way, the fishing line L is wound from the end on the end plate 103b side of the winding core 103a of the spool 103 as shown in FIG. Winding of is started.

  When the fishing line L starts to be wound around the winding core 103a of the spool 103, the fishing line L is urged into contact with the inner surface of the end plate 103b, so that the fishing line L is attached to the end of the winding core 103a on the end plate 103b side. From the part, it can be wound with the interval between the adjacent parts close.

  After the winding of the fishing line L around all the winding cores fitted on the drive shaft 5b of the motor 5 is finished, the driving of the motor 5 is stopped and the fishing line is connected between the yarn feeding port of the pulley 8 and the winding core. Cut L.

  Hereinafter, the effect which this embodiment has is explained.

  In the yarn winding device described in Patent Document 1, the fishing line is wound next to one end plate of the first bobbin member after the fishing line is wound around the first bobbin member (one spool). The fishing line is pressed against and contacted with the inner surface of the end plate of the second bobbin winding member (next spool) to be rotated. For this reason, it is necessary to control the position of the guide rod with high accuracy in the axial direction of the core of the second bobbin winding member so that there is no gap between the fishing line and the inner surface of the end plate. Control was complicated and costly.

  On the other hand, in this embodiment, the pin member 45 of the fishing line urging mechanism 31 pushes and pushes the fishing line L by contact with the fishing line L that the pulley 8 is fed, so that the fishing line L becomes the end plates 101c and 103b. It is only necessary to protrude beyond the core 103a. For this reason, the rotational position control of the pin member 45 does not need to be highly accurate, and it is sufficient if it is performed by simple and low-cost drive control of the air cylinder 33. Thereby, by simple and low-cost control, the fishing line L can be brought into contact with the inner surface of the end plate 103b, and preparations can be made for winding the fishing line L from the axial end of the winding core 103a.

  Furthermore, in the yarn winding device described in Patent Document 1, in order to press the fishing line against the inner surface of the end plate of the second bobbin member by the guide rod, a guide pulley that feeds the fishing line in advance is connected to the first bobbin member and the first bobbin member. It is necessary to move to the winding core side of the second bobbin member over the end plates adjacent to the two bobbin members.

  On the other hand, in the present embodiment, the portion that protrudes toward the winding core 103a due to the pushing bias of the pin member 45 with respect to the fishing line L is biased by the lever member 55, and the yarn winding preparation control means 57 is connected to the pin member 45 and the lever. By releasing the urging of the member 55 to the fishing line L, the fishing line L comes into urging contact with the inner surface of the end plate 103b. Therefore, in order to bring the fishing line L into contact with the inner surface of the end plate 103b, it is not necessary to move the pulley 8 in advance to the core 103a side of the spool 103 beyond the end plates 101c and 103b. Thus, after the winding of the fishing line L around the winding core 101a is completed by the amount the moving distance of the pulley 8 is shortened, the winding of the fishing line L around the winding core 103a can be started immediately.

  In the second embodiment of the present invention, as shown in FIG. 8, a vertical member 59 as first thread urging means extending in the vertical direction, and a second thread urging extending from the upper end of the vertical member 59 in the drive shaft direction. An L-shaped member 63 including a lateral member 61 as a means is provided so as to be movable in parallel in the vertical direction and the drive shaft direction. That is, the vertical member 59 and the horizontal member 61 are integrally formed, and the urging operation for each fishing line L is performed by one L-shaped member 63.

  According to this embodiment, by moving the L-shaped member 63 from the spool 101 side to the spool 103 side, the vertical member 59 is urged against the fishing line L fed out of the pulley 8, and the fishing line L is moved to the end plate 101c. , 103b and protrudes to the core 103a side. Then, while the vertical member 59 urges the fishing line L, the L-shaped member 63 is moved vertically downward so that the portion where the horizontal member 61 protrudes to the core 103a side of the fishing line L is used as the axis of the winding core 103a. Energize in the approaching direction.

  In this way, by forming the first yarn urging means and the second yarn urging means integrally, the manufacturing cost of the first yarn urging means and the second yarn urging means can be reduced.
