It is called a guide arm 45 for a core wire, a guide arm 55a for filaments, and a guide arm 55b for filaments. A balance portion 57a and a balance portion 57b are attached to the first drive shaft 25a and the second drive shaft 25b. The balance portion 57a, the balance portion 57b, the first filament guide portion 55a, and the second filament are attached to the first drive shaft 25a and the second drive shaft 25b. The guide portion 55b extends symmetrically with respect to the central axes of the first drive shaft 25a and the second drive shaft 25b. The balance portion 57a and the balance portion 57b have a flat plate shape similarly to the first filament guide portion 55a and the second filament guide portion 55b, and are used to make the load applied to the central axis during rotation uniform.

Further, the first drive shaft 25a and the second drive shaft 25b are provided to rotate in synchronization with each other by a motor (not shown) and a power transmission mechanism.

The first filament guide portion 55a is attached to the first drive shaft 25a, and the first filament guide portion 55a is a thin plate-shaped member having a width direction smaller than the height direction, and is in the axial direction of the first drive shaft 25a ( It also extends from the first drive shaft 25a in the vertical direction in the front-rear direction. A filament insertion hole 56 through which the filament M is inserted is formed in one end portion of the first filament guide portion 55a so as to penetrate therethrough. The second filament guide portion 55b of the thin plate-like member similar to the first filament guide portion 55a is attached to the second drive shaft 25b. A filament insertion hole 56 through which the filament M is inserted is formed in one end portion of the second filament guide portion 55b so as to penetrate therethrough. In addition, the first filament guide portion The 55a and the second filament guide portions 55b are set to rotate in the same phase. When the first filament guide portion 55a and the second filament guide portion 55b are rotated, the filament M passing through the filament insertion hole 56 is rotated around the core bobbin B. By this rotation, the monofilament M is wound around the core wire S passing through the mandrel 101, and is formed into a wound sprocket by the screw 102.

Further, a bearing (not shown) is provided on the inner circumferential surface of the second drive shaft 25b, and the fixed shaft 25c is inserted into the bearing. Therefore, the fixed shaft 25c is supported by the second drive shaft 25b so that the second drive shaft 25b is rotatable. Further, a mandrel 101 is fixed to the rear end portion of the fixed shaft 25c. Further, a through hole 26 for passing the core wire S toward the mandrel 101 side is formed on the central axis of the fixed shaft 25c.

The central axes of rotation L2 are parallel to each other and do not intersect in the width direction.

As shown in FIGS. 1 and 2, the bobbin support portion 30 includes a first side plate portion (first portion) 31a rotatably supported by the first drive shaft 25a, and a second side plate portion (second portion) 31b. The second drive shaft 25b is rotatably supported; the connecting plate 32 connects the first side plate portion 31a and the second side plate portion 31b in the front-rear direction; and the bobbin holder 33 supports the core bobbin B. The first side plate portion 31a and the second side plate portion 31b are flat plates that extend in the vertical direction and the horizontal direction.

The first side plate portion 31a includes a bearing (not shown), and a rear end portion of the first drive shaft 25a is inserted into the bearing. Therefore, the first side plate portion 31a is supported by the first drive shaft 25a so that the first drive shaft 25a is rotatable. The second side plate portion 31b is fixed to the front end portion of the fixed shaft 25c. Therefore, the second side plate portion 31b is one of the fixed shafts 25c. It is rotatably supported with respect to the second drive shaft 25b. That is, the second drive shaft 25b rotates around the fixed shaft 25c.

Thereby, when the first drive shaft 25a rotates, the first drive shaft 25a is rotated in the bearing of the first side plate portion 31a by the bearing of the first side plate portion 31a, and when the second drive shaft 25b is rotated, The bearing of the second wall portion 21b rotates the second drive shaft 25b in the bearing of the second wall portion 21b. Further, since the connecting plate 32 is connected to the first drive shaft 25a and the second drive shaft 25b via the first side plate portion 31a and the second side plate portion 31b, the first drive shaft 25a and the second drive shaft 25b are offset and disposed.

Further, in the upper and lower pair of shaft support portions 66 and the rotation portion 67, a shaft insertion hole 66a and a shaft insertion hole 67a through which the rotation shaft 68 is inserted are formed in the vertical direction. The rotating shaft 68 is fixed to the rotating portion 67 by screws so that both ends thereof protrude from the rotating portion 67. Further, the rotation shafts 68 protruding from the rotation portion 67 are respectively inserted into the shaft insertion holes 66a of the upper and lower shaft support portions 66, so that the rotation portion 67 is rotatable. Therefore, the rotating shaft 68 is disposed in a direction orthogonal to the longitudinal direction and the width direction of the connecting plate 32, that is, in the vertical direction. Therefore, the bobbin guide plate 36 side of the bobbin holder 33 can be swung to the left side in the width direction around the rotation shaft 68 of the hinge portion 65.

Further, the swing of the bobbin holder 33 can be rotated from the initial position to about 90 degrees, but the swing angle required for the replacement is about 50 degrees. Moreover, the swing angle can also be limited. In this case, the operation can be completed as compared with the case where the work place is rotated by 90 degrees in the swing state, and the swing angle is small. Further, the above-described swing is horizontally rotated, but it is also possible to swing in the upward direction in the vertical direction perpendicular to the horizontal plane. In this case, the core bobbin B is replaced from the upper side of the winding element forming device 100.

As shown in FIGS. 1 and 2, the guide supporting portion 50 for supporting the core wire guiding portion 45 is a substantially annular member, and a fitting convex portion 51 is formed on one surface thereof, and the fitting convex portion 51 is detachably fitted. The inner circumferential surface of the bobbin guide plate 36 of the bobbin holder 33. Therefore, the guide supporting portion 50 including the core wire guiding portion 45 can be detachably attached to the bobbin guiding plate 36 which is the front end portion of the bobbin holder 33.

Further, a core guide portion 45 and a balance portion 46 are attached to the center portion of the guide support portion 50, and the core guide portion 45 extends in a direction perpendicular to the front-rear direction, and the length thereof exceeds the core wire S around the core bobbin. The portion of the diameter in the state of B is bent to the front side and has a substantially L shape, and the balance portion 46 extends symmetrically with the core guide portion 45 around the central axis of the guide support portion 50, and is substantially L. Word shape. Similarly to the core guide portion 45, the balance portion 46 has a flat shape for making the load applied to the central shaft during rotation uniform. In addition, the balance portion 46 may not be required.

Further, the core wire guide portion 45 is formed with a first core wire insertion hole 45a and a second core wire insertion hole 45b through which the core wire S is inserted. In addition, the core wire S wound from the core bobbin B is inserted into the first core wire insertion hole 45a from the outer side of the core wire guide portion 45 toward the core wire guide portion 45, and then pulled out from the core wire guide portion 45 in the backward direction. The outer side is inserted into the second core wire insertion hole 45b toward the core bobbin B side. Further, a guide portion 45c that guides the core wire S that has passed through the first core wire insertion hole 45a and the second core wire insertion hole 45b to the core wire buffer described below is formed in the center portion of the guide support portion 50 ( Buffer) mechanism 80.

Further, in the present embodiment, as shown in FIG. 1, a locking mechanism 75 is provided in the hinge portion 65. As shown in FIGS. 3, 4, and 5, the locking mechanism 75 includes a first engaging hole 76a along the side. The vertical direction is formed in the rotating portion 67 of the hinge portion 65; the two second engaging holes 76b are connectable to the first engaging hole 76a, and are formed in the vertical support portion 66 in the vertical direction; the locking pin 77 is locked. When the mechanism 75 is locked, the upper side is inserted into the first engagement hole 76a and the two second engagement holes 76b; and the pin support portion 78 is protruded forward and provided on the left end surface of the first side plate portion 31a, and the lock pin is attached. 77 can be supported by sliding up and down.

Further, a first pin insertion hole 78a through which the lock pin 77 is inserted is formed in the pin support portion 78 in the vertical direction. Further, a second pin insertion hole 78b through which the lock pin 77 is inserted is formed in the connecting plate 32 in the vertical direction.

Further, a hanging bolt 79 is attached to the left end surface of the first side plate portion 31a so as to protrude in the right direction, and the hanging bolt 79 is locked at the locking mechanism 75. At this time, the lock pin 77 is restricted from sliding downward by hooking the operation piece 77a of the lock pin 77. The operation piece 77a extends perpendicularly to the longitudinal direction of the lock pin 77.

Here, the locking by the lock mechanism 75 means that the lock pin 77 is inserted across the first engagement hole 76a of the rotation portion 67 and the second engagement hole 76b of the upper and lower shaft support portions 66. Thereby, the bobbin holder 33 cannot be swung around the rotation shaft 68 of the hinge part 65. Further, the unlocking state refers to a state in which the operation piece 77a of the lock pin 77 is disengaged from the hook bolt 79 and the lock pin 77 is slid in the downward direction, so that the upper end of the lock pin 77 is rotated from the first engagement hole 76a of the rotary portion 67. It is pulled out and located in the second fastening hole 76b of the lower shaft support portion 66. Thereby, the bobbin holder 33 can be swung around the rotation shaft 68 of the hinge portion 65.

A substantially L-shaped bracket 60 is attached to an inner side surface (rear side surface) of the front side wall 21a of the casing 20, and the bracket 60 extends from the inner side surface to a lower side of the locking pin 77 of the locking mechanism 75. The frame 60 is formed with a third engagement hole 60a in the vertical direction, and the third engagement hole 60a is inserted by the lower side of the lock pin 77 when the lock mechanism 75 is unlocked. Further, when the lock is released, the operation piece 77a abuts against the upper surface of the pin support portion 78, and the slide pin 77 is stopped in the downward direction. In this state, the lower side of the lock pin 77 is inserted into the bracket. The third fastening hole 60a of 60 is engaged with each other. Therefore, the first engagement hole 76a, the second engagement hole 76b, the first pin insertion hole 78a, the second pin insertion hole 78b, and the third engagement hole 60a are in a closed state of the hinge portion 65. When the positions are equal to each other in the vertical direction, the lock pin 77 can be slid up and down and inserted into the first engagement hole 76a, the second engagement hole 76b, the first pin insertion hole 78a, the second pin insertion hole 78b, and the like. And the third fastening hole 60a.

Further, as shown in FIGS. 1 and 7, the bobbin supporting portion 30 is provided with a core buffer mechanism 80, and the core buffer mechanism 80 is empty from the core bobbin B. The core S supplied to the mandrel 101 is accumulated while the driving of the winding element forming device 100 is stopped.

The core buffer mechanism 80 includes a base portion 81 that is provided on a surface of the second side plate portion 31b on the side of the core guide portion 45, and a tension adjustment portion 82 that is attached to the left end surface of the base portion 81 and is adjusted.

When the wound sprocket formed in the tension adjusting portion 82 is discharged from the winding sprocket molding apparatus 100 in accordance with the rotation of the screw 102, the tension is adjusted so that the tension in the discharge direction becomes a predetermined value, and the tension is adjusted by the tension. The portion 82 takes out the core wire S from the core bobbin B. The core wire guiding portion 45 is rotated in the direction opposite to the winding direction of the core wire S around the core bobbin B by stretching the core wire S, whereby the core wire S is separated from the core bobbin B, and the separated core wire S is buffered by the core wire. The mechanism 80 is derived and supplied to the mandrel 101. Therefore, the mechanism for driving is not provided for the rotation of the core guide portion 45.

In the core wire supply device 10 configured as described above, the upper side of the lock pin 77 is inserted into the first engagement hole 76a of the rotary portion 67 of the hinge portion 65 and the upper and lower shaft supports by sliding the lock pin 77 upward. In the second engagement hole 76b of the portion 66, the lock mechanism 75 is in the locked state, and the bobbin holder 33 cannot swing (see Fig. 4). Further, the lower side of the lock pin 77 is inserted into the third engagement hole 60a of the bracket 60 by sliding the lock pin 77 downward, whereby the lock mechanism 75 is released, and the bobbin holder 33 can swing (refer to the figure). 5).
