Abstract

PROBLEM TO BE SOLVED: To errorlessly detect slack generated on the lower stream side of the position where a filamentary body is pinched so as to prevent winding shift of the filamentary body from failing, when the filamentary body is pinched and windingly shifted to an empty spool while taking out the filamentary body at higher speed than winding speed, between a full wound side spool and the empty spool. SOLUTION: After a filamentary body 1 is shifted form a spool 10A to a spool 10B, displacement of a movable dancer roller 136 is restrained so as to add larger tension than ordinary winding tension to the filamentary body 1, thereafter the filamentary body is guarded by a wireguard member 104, then advanced to the position where the filamentary body 1 is pinched, and pinched by presser rollers 54, 54'. Consequently, taking out control of the presser roller 54' on the drive side is not begun before the filamentary body 1 is guarded by the wire guard member 10, and hence fail of winding shift of the filamentary body is not generated.

[0002]

2. Description of the Related Art The present applicant has previously proposed that a continuous winding machine that sequentially winds a long filament on bobbins on a plurality of spoolers is used when the filament is rewound from an empty spooler. , By pulling the wire between both spoolers at a speed faster than the winding speed and sandwiching it, even if the long wire is wound at a high speed, the wire on the fully wound side may become abnormal or broken. There is proposed a method and an apparatus for winding a linear body of a continuous winding machine for a long linear body which does not cause damage (Japanese Patent Application No. 6-170).
458).

This device, as shown in FIG. 29, includes at least two spoolers 10A and 10B and a second spooler (waiting side or working side spooler) 10A which is waiting for winding and a second spooler which is waiting. (Spooler on the empty side or standby side)
When winding the filamentous body 1 to 10B, the spooler 10 on the operating side
The linear body shift mechanism 32 including the shift pulley 38 for shifting the linear body 1 from the bobbin 12A on A to the bobbin 12B on the standby side spooler 10B and the winding start end of the linear body 1 provided on each spooler 10A, 10B. Capture claw 2 for capturing 1a
The catching members 28A, 28B having 6A, 26B and the catching member 28A by hooking the catching member 1 when the catching member 1 is wound.
28B, and the striation body winding device 34 including the striation body gathering mechanism 34, and the capturing member 28B of the standby side spooler 10B waits for the working side spooler 10A before the filament body 1 is captured and cut. A pair of pressing rollers (pinch rollers) 5 for sandwiching the linear body 1 to be wound between the side spooler 10B and the side spooler 10B so as to be drawn at a speed higher than the winding speed.
4, 54 ', and the wire-hanging member (looper member) 104 that is displaced so as to absorb the slack of the filament 1 generated on the downstream side of the nipping position of the filament 1.
And a slack absorbing means 100 including. When the displacement amount of the wire hooking member 104 of the slack absorbing means 100 is smaller than a predetermined displacement amount, the control means (not shown) speeds up the restraining rollers 54, 54 'of the linear body holding mechanism 36 (the peripheral speed of the rollers). If the displacement amount of the wire hooking member 104 of the slack absorbing means 100 is larger than the predetermined displacement amount, the linear body holding mechanism 3
6 to control the take-up of the filamentous body 1 by driving the constraining rollers 54 and 54 'so as to decelerate the constraining rollers 54 and 54' (to lower the peripheral speed of the rollers) and to fully wind the filamentous body clamping mechanism 36. Appropriate tension is applied to the linear body 1 with the side spooler 10A.

In the control means (not shown), the linear body shift mechanism 32 operates the spool 1 on the operating side (full winding side) of the linear body 1.
After shifting from 0A to the spooler 10B on the standby side and the pressing rollers 54 and 54 'of the linear body clamping mechanism 36 clamp the linear body 1, the linear hooking member 104 of the slack absorbing means 100 is released from the non-lined position. After a predetermined time, for example, 0.4 seconds, the pulling control of the filament 1 by the pressing rollers 54, 54 'of the filament sandwiching mechanism 36 is started, and after this control is started,
For example, this take-up control is repeated every 0.025 seconds.

The filament 1 is wound around the bobbin 12A on the spooler 10A on the operating side, and is wound on the bobbin 12A.
When the filamentous body 1 is fully wound, the filamentous body shift mechanism 32 first moves the shift pulley 38 to the bobbin 12 as shown in FIG.
Bobbin 12 on spooler 12B from the position of the dotted line above A
It moves toward the solid line position above B and shifts the linear body 1 so as to intersect the bobbin 12B. After that, the pair of restraining rollers 54, 54 ′ of the linear body sandwiching mechanism 36 is attached to the linear body 1
And holding the pressing rollers 54, 54 'at a speed higher than the winding speed of the filament 1 (for example, 1000 m / min when the filament 1 is an optical fiber) (for example, an increase of 1% of the winding speed). 1010 m / min), and then the linear body moving mechanism 34 hooks the linear body 1 to a position where it contacts the catching member 28B of the bobbin 12B, and the linear body 1 is caught by the catching member 28B of the bobbin 12B. The striatum 1 is captured by the capturing claw 26B of the bobbin 12A and the bobbin 1
Fix with 2B. Therefore, the striatum 1 is the bobbin 1
The filamentous body 1 after the portion fixed to the bobbin 12B is torn and cut off between the bobbins 12A and 12B by the rotation of the bobbin 12B by the rotation of the bobbin 12B.
The winding end portion of the filamentous body 1 which is wound around B and torn off from the portion fixed to the bobbin 12B is wound around the bobbin 12A.

In this apparatus, the filament body 1 is a bobbin 12A.
And 12B are sandwiched between the pair of restraining rollers 54, 54 ', and are drawn at a speed higher than the winding speed, so that the filament 1 is connected to the bobbin 12A and the pair of restraining rollers 54, 54'. ', So that when the filamentous body 1 is cut between the standby spooler 10B and the pair of restraining rollers 54, 54', it is wound on the bobbin 12A which continues to rotate during this time. Excessive tension is not applied to the attached linear body 1, and the wound portion of the linear body 1 on the bobbin 12A is not adversely affected.

A pair of restraining rollers 54 and 54 'are shown in FIG.
As shown in (A) to FIG. 30 (B), the first pressing roller 54 rolls on the peripheral surface of the second pressing roller 54 'around the axis of the second pressing roller 54'. While revolving so as to revolve, the linear body 1 is held by these restraining rollers 54, 5
It is preferable to sandwich it in a substantially S shape so as to engage with the peripheral surface of 4 ', because the sandwiching effect of the restraining rollers 54, 54' is further improved.

In current technology, a pair of restraining rollers 54,
After the first holding roller 54 starts to circulate around the second holding roller 54 ′ by sandwiching the linear body 1 by 54 ′, the linear member 1 is attached to the line hooking member 104 so that the linear body 1 is hooked. The hanging member 104 is released from the non-line hanging position (lock position) (a) in FIG. 31 and is displaced upward to absorb the looseness of the filamentous body 1. Then, in order to appropriately maintain the tension of the filamentous body 1 between the position where the filamentous body 1 is sandwiched by the restraining rollers 54, 54 ′ and the spooler 10A in which the filamentous body 1 is actually wound up, the wire hanging member 104 Is detected and the drive control of the restraining rollers 54, 54 '(take-up control or tension control of the filament 1) is performed. As described above, the filament take-up control is performed as described above. After the hanging member 104 starts to move in the hanging direction (upward) from the non-hanging position (a) in FIG. 31,
That is, it starts after a predetermined time, for example, 0.4 seconds, after the line hanging member 104 is released from the non-line hanging position. The wire hanging member 104 is slowly lifted by a damper such as an air cylinder. However, if the rising speed is too low, even if the filamentous body 1 is taken up with an appropriate amount of slack as shown by the solid line in FIG. 31, When the line hanging member 104 reaches the position (b) before the target position (c) in FIG. 31, that is, before the line hanging member 104 touches the line body 1 and lines the line body 1, the control is performed. Striation body 1 by means of restraining rollers 54, 54 '
The take-up control of may be started.

As described above, the wire-hanging member 104 has the filament body 1.
The control roller 54, 54 'before
When the take-up control of the filamentous body 1 is started by, the hooking member 104 is located before the predetermined position (target displacement position) shown by the symbol (c) in FIG. Even though there is no slack, it is erroneously determined that the slack is insufficient, and the suppressing rollers 54, 54 'are controlled to accelerate. For this reason, as shown by the broken line in FIG. 31, a larger slack is imparted to the linear member 1, so that the linear member 1 cannot linearly hook the linear member 1 and continues to rise. When the wire hooking member 104 reaches the position (d) in FIG. 31 when the control means performs the next control, the wire rope body 1 is not actually hooked yet. It is judged that the slack of 1 is too large, and the pressing rollers 54 and 54 'are decelerated.

Suppressing rollers 54, 5 of the linear body clamping mechanism 36
When the 4 ′ repeats such rapid acceleration and deceleration in this way, when the restraining rollers 54, 54 ′ are rapidly controlled in the deceleration direction, the shift pulley 38 of the filament shift mechanism 32 and the filament sandwiching mechanism. The linear body 1 is loosened between the pressing rollers 54 and 54 ′ of 36, and thus the linear body 1 is the spooler 10 </ b> B.
The filament member 1 cannot be reliably trapped on the bobbin 12B because the filament member 1 cannot be caught on the capturing claw 26B of the side capturing member 28B, or the filament member 1 is disengaged from the holding rollers 54, 54 '. There was a possibility that the re-rolling failure would occur.
On the contrary, when the restraining rollers 54, 54 ′ are rapidly controlled in the speed increasing direction, between the shift pulley 38 of the filament shift mechanism 32 and the restraining rollers 54, 54 ′ of the filament holding mechanism 36. Excessive tension is suddenly applied to the filamentous body 1 to break the filamentous body 1 before the filamentous body 1 is captured by the bobbin 12B on the side of the empty spooler 10B, and similarly, there is a risk of failure in rewinding the filamentous body 1. was there.

[0011]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that the filament body is erroneously controlled to be pulled between the filament body shift mechanism and the filament body pinching mechanism and suddenly sags or abruptly. It is an object of the present invention to provide a filament winding control device for a continuous winding machine of a long filament that prevents a large amount of tension from being applied to the filament to cause a failure in winding the filament.

[0012]

The first means for solving the problems of the present invention is to shift the filament to be wound from the bobbin on the first spooler to the bobbin on the second spooler, and then to move the second filament.

When rolling the striatum from the bobbin on the first spooler to the bobbin on the second spooler by fixing the striatum,
The first before the striatum is captured and cut by the second spooler
Between the spooler and the second spooler, a filamentous body clamping means including a pressing roller for clamping the filamentous body so as to pull it at a speed higher than its winding speed, and a downstream side of the filamentous body clamping means. Detecting the amount of slack absorption of the slack absorbing means by the slack absorbing means including a hooking member that is displaced so as to absorb the slack of the linear body that is generated and the take-up of the linear body by the holding roller of the linear body clamping means. In the filament winding control device for the continuous filament winding machine having a controller for controlling the filament, the controller releases the filament catching member of the slack absorbing means from the non-corriding position. The continuous winding of a long filament is characterized in that after the filament is hooked on the hanging member, the filament is suppressed and sandwiched by rollers to start the take-up control of the filament. The object of the present invention is to provide a control device for winding the filament of the machine.

According to a second object solving means of the present invention, in the linear object winding control device of the continuous winding machine for a long linear object according to the first object solving means, the hanging member of the slack absorbing means is not Before being released from the line hanging position, the first spooler and the upstream side of the linear body clamping means are arranged so as to maintain the linear body in a position where the linear body extends between the pressing rollers and can sandwich the linear body. Between the long filaments and the filament winding-up control device, further comprising a tension increasing means for applying a greater tension to the filaments than the tension during normal winding. To provide.

A third problem solving means of the present invention is a filament winding control device for a continuous winding machine for long filaments according to the first or second problem solving means 1, which comprises: The sandwiching means has a configuration in which the sandwiching of the linear members moves one holding roll around the center axis of the other holding roll so that the linear members come into contact with the peripheral surfaces of the both holding rolls. It is an object of the present invention to provide a filament winding control device for a continuous winding machine for a long filament.

A fourth means for solving the problems of the present invention is to install the filament on the second spooler after shifting the filament to be wound from the bobbin on the first spooler to the bobbin on the second spooler. The filamentous body is fixed relatively to the bobbin on the second spooler by moving the filamentous body relatively to the bobbin on the second spooler toward the capturing member that captures the winding start end of the filamentous body. Thus, when the striatum is transferred from the bobbin on the first spooler to the bobbin on the second spooler, the first spooler and the second spooler are caught before the striatum is captured and cut by the second spooler. And a spooler, which sandwiches the linear body at a speed faster than the winding speed, and a linear body clamping means including a pressing roller, and a linear body generated downstream of the linear body clamping means. Slack absorbing means including a hanging member that is displaced so as to absorb the slack of A filament winding device for a continuous winding machine for long filaments, which has a control means for controlling the take-up of the filament by the holding roller of the filament clamping means by detecting the amount of slack absorption of the slack absorbing means. The transfer control device includes a line-locking position detecting unit that detects a change in the position of the line-hanging member of the slack absorbing unit, and the control unit changes the position of the line-marking detected by the line-locking position detecting unit per unit time. When it becomes smaller than a predetermined value, it includes a judgment circuit unit for judging that the linear member has been drawn on the hanging member, and this judgment circuit unit judges that the linear member has been drawn on the hanging member. The present invention is to provide a filamentous body winding control device for a long filamentous body continuous winder, characterized in that it is configured to start the filamentous body take-up control by the pressing roller. .

A fifth problem solving means of the present invention is a filament winding control device for a continuous winding machine for long filaments according to the second problem solving means 4, wherein the filament sandwiching means is , A continuous winding machine for long filaments in which one of the retaining rolls is rotated around the central axis of the other retaining roll to draw the filaments while contacting the circumferential surfaces of both retaining rolls. The object of the present invention is to provide a filament winding control device.

In this way, when the filamentous body is wound from the first spooler to the second spooler, the filamentous member of the slack absorbing means is released from the non-liner position and the filamentous member is attached to the filamentous member. After the wire is hooked, the linear body is sandwiched by the restraining rollers and the take-up control of the linear body is started.The amount of looseness absorbed by the loosening absorbing means is accurately detected. The slack is not controlled by an erroneous slack in the striated body, and therefore the slack and excessive tension are not generated in the striated body upstream of the position where the striated body is sandwiched.
Therefore, due to a large slack in the striatum, it may be caught on the catching claw of the spooler on the side to be rolled up, or
The filament does not come off from the pinched position, the winding of the filament does not fail, and the wire is disconnected before it is caught due to excessive tension of the filament. It does not cause the failure of winding the striatum.

In addition, before releasing the wire hooking member of the slack absorbing means from the non-wire hooking position, the wire rope member is maintained in a position where it extends across the pressing rollers to sandwich the wire rod member. When a tension larger than the tension at the time of normal winding is applied to the linear member between the spooler of No. 1 and the upstream side of the linear member clamping means, the linear member is released from the non-linear position and the linear member is attached to the linear member. Even if it is hung on the wire, the strip line does not hinder the forward movement of the pressing roller of the strip sandwiching means, and the strip body is securely sandwiched and the winding operation of the strip body does not fail.

Further, when the change per unit time in the position of the hooking detected by the hooking position detecting means for detecting the change in the position of the hooking member of the slack absorbing means becomes smaller than a predetermined value. If it is determined that the holding roller has started pulling control of the linear body after it has been determined that the linear body has been drawn on the member, the amount of slack absorption of the slack absorbing means will not be erroneously detected. The pulling-out control of the filamentous body is performed with high precision, and excessive slack or excessive tension is not generated in the filamentous body on the upstream side of the filamentous body sandwiching position. Therefore, due to the large slack, the filament does not get caught on the catching claw of the spooler of the spooler on the side to be rolled up, and the filament does not come off from the pinched position, and the filament fails to roll. In addition, the filament does not break before the filament is caught by the excessive tension of the filament and the winding of the filament fails.

And the line-drawing rod 5 that is arranged between the liner 1 and the liner 1 and moves the line-shaped body 1 to the catching claw 26B of the catching member 28B of the second spooler 10B.
As shown in FIG. 8, the linear rod 50 is connected to the piston rod 52a of the advancing / retreating cylinder 52 so that the linear member 1 can be pulled up toward or away from the linear member 1. To be retreated. In addition, the linear member 1 captures the member 28
It is needless to say that the bobbin 12B of the second spooler 10B may move toward the line body 1 side instead of the line drawing rod 50 pulling the line body 1 in order to draw it toward B. .

As shown in FIGS. 1, 5 and 8, the linear member clamping means 36 comprises a pair of restraining rolls 54, 54 'in the form of pinch rolls having a pulling function. 54 'are positions retracted from the winding portion of the filamentous body 1 (see FIG. 2) and positions where the filamentous body 1 is pinched by advancing to the winding portion of the filamentous body 1 (see FIGS. 4 and 5). ) Move back and forth between. These restraining rolls 54, 54 'are shown in FIG. 8 in particular.
The taper part 54
a, 54'a.

In the illustrated embodiment, the pair of restraining rolls 54 and 54 'have a small gap, for example, about 5 mm, in the non-sandwiched state of the linear body, as shown in FIGS. 5, 16 and 17. Since the filaments 1 face each other with a gap of, the filaments 1 are not clamped or pulled apart only by inserting the filaments 1 between them. The linear body sandwiching means 36, as will be described later, includes one holding roll 54.
After the gap is contracted so as to be pressed against the other restraining roll 54 ', one restraining roll 54 revolves around the circumference of the other restraining roll 54' by the roll circumferential movement means described later in detail. These restraining rollers 54, 5
The linear body 1 is sandwiched in contact with a part of the peripheral surface of 4 '.

In order to reduce the gap between the restraining roll 54 and the restraining roll 54 ', as shown in FIG. 8, the roll shaft 54b of the restraining roll 54 is provided with a driving source for driving in the radial direction, for example, a twin rod cylinder 56. The twin roll cylinder 56 is mounted on the twin rod cylinder 56.
It can be opened and closed with respect to the pressing roll 54 '.

The holding roll 54 'is a holding roll on the drive side which is rotationally driven by the rotation driving means 58 shown in FIG. 8, and the holding roll 54' is the holding roll 54 '.
It is a suppression roll on the driven side that is driven by. The peripheral speed (take-up speed of the filament 1) (Vb) and the take-up speed (Vw) of these restraining rolls 54, 54 'are V
It is set so that b> Vw. Therefore, the filamentous body 1 is sandwiched between the restraining rolls 54, 54 'and taken up by the drive of the restraining roll 54' to be loosened on the downstream side of the filamentous body clamping means 36.
There is no influence of the tension applied to the filamentous body 1 from the upstream side of 4, 54 '. .

It comprises a belt / pulley mechanism 68 including a belt 66 which is stretched around 2, 64. As described above, the drive-side restraining roll 54 'is rotationally driven so as to draw the filamentous body 1 at a speed higher than the winding speed. The restraining roll 54 ′ may be taken up at the same speed as the winding speed of the filament 1. However, it is practically difficult to synchronize the take-up speed by the restraining roll 54 with the winding speed, and therefore, the holding roll 54 ′. It is practical for 54 'to take up the filamentous body 1 at a speed higher than the winding speed.

As shown in FIG. 8, the roll rotating means 70 is supported via a bearing 76 on a holding cylinder 74 which supports the roll shaft 54'b of the drive-side restraining roll 54 'via a bearing 72. The rotary cylinder 78 and this rotary cylinder 78
The rotary drive source 80 drives the rotary motor 82 to rotate, and the rotary drive source 80 includes a rotary motor 82 mounted on the holding cylinder 74 via a bracket 75, a drive gear 84 rotationally driven by the rotary motor 82, and The driven gear 86 meshes with the drive gear 84 and is integrally formed with the rotary cylinder 78. A twin rod cylinder 56 for advancing and retracting the driven roll 54 is supported on the rotary cylinder 78. Therefore, when the rotary motor 82 is rotationally driven, the rotary cylinder 78 rotates about the axis of the roll shaft 54′b of the restraining roll 54 ′ via the drive gear 84 and the driven gear 86. While revolving around while engaging with the peripheral surface of the pressing roll 54 ', it revolves around the central axis of the pressing roll 54'. In FIG. 8, reference numeral 85 is a pressing roller 5.
4 is an encoder that is driven via a driven gear 85A that meshes with the drive gear 84 to detect the circumferential position of No. 4.

The roll circling means 70 is driven after the pressing roll 54 is closed so as to come into pressure contact with the pressing roll 54 ′, so that the linear body 1 moves as the pressing roll 54 circulates. While gradually engaging with the peripheral surface of the holding roll 54 at a large angle, it also engages with the peripheral surface of the restraining roll 54 at a gradually increasing angle. It is transformed into the state where it did.

As shown in FIG. 8, the pressing rolls 54, 5

Carriage 9 guided along a linear guide rail 92
4 and an advancing / retreating cylinder 96 having a piston rod 96a attached to the frame 90 and connected to the carriage 94.
4 is mounted on the carriage 94 via a frame 98. Therefore, the piston rod 96 of the advancing / retreating cylinder 96
When a is extended, both restraining rolls 54, 54 'advance to the linear body sandwiching position (see the solid line position in FIG. 4 or FIG. 9), and conversely, when the piston rod 96a of the advancing / retreating cylinder 96 contracts, both restraining rolls 54, 54' The rolls 54, 54 'retract from the position where the filament is clamped (see the imaginary line position in FIG. 2 or 9).

As shown in FIGS. 1, 6 and 7, the filament-rolling device portion 30 is disposed between the filament-clamping means 36 and the spooler 10A or 10B, and the restraining roll 54,
Further, there is further provided slack absorbing means 100 for absorbing the slack of the filamentous body 1 caused by making the peripheral speed of 54 'faster than the winding speed of the filamentous body 1.

Details of the slack absorbing means 100 are shown in FIGS. 9 and 10. The slack absorbing means 100 includes a V-shaped wire hanging member (looper member) 104 fixed to one end of the swing rod 102, and the swing rod 102, as shown in FIG. Is pivoted to. The swing rod 102 has a balance weight 110 attached to the other end, and therefore the swing rod 102 is
The balance weight 110 is urged so as to swing clockwise in FIG.

As shown in FIG. 9, a stopper 112 is provided on the frame 108, and the stopper 112 has a function of preventing the swing rod 102 from swinging counterclockwise beyond the position shown by the solid line in FIG. Have. Also, as shown in FIG.
An air cylinder 114 for locking is provided on the frame 108, and the air cylinder 114 includes the piston rod 1
The swing rod engaging member 116 is provided on the upper portion of 14a. The rocking rod engaging member 116 is engaged between the pivotally supporting portion 102a of the rocking rod 102 and the balance weight 110 to control the position of the line hanging member 104 and the rocking movement speed of the rocking rod 102. are doing. FIG. 9 shows that the piston rod 114a of the locking air cylinder 114 extends so that the wire hooking member 104 is locked at the non-wire hooking position (non-operating position) below the filament gripping means 36. There is. still,
The balance weight 110 can be omitted by setting the position of the pivotally supporting portion 102a of the swinging rod 102 so that the center of gravity of the swinging rod 102 is located on the side opposite to the hanging member 104.

As will be described later in detail, after the filament 1 is inserted between the restraining rolls 54, 54 'of the filament holding means 36, the twin rod cylinder 56 shown in FIG. The linear body 1 is sandwiched between the pressing rollers 54 'and 54' by being pressed against the pressing roller 54 ', and one pressing roller 54 is rotated around the other pressing roller 54' by the roll peripheral movement means 70. Then, while the linear body 1 is partially engaged with the circumferential surfaces of the two restraining rollers 54, 54 ', the circumferential speed of these restraining rolls 54, 54' is made faster than the linear velocity of the linear body 1. , The linear body 1 is loosened on the downstream side of the linear body clamping means 36, but the pressing roller 54,
Before the wire 54 'sandwiches the linear body 1, the slack absorbing means 100
When the piston rod 114a of the locking cylinder 114 is contracted to release the lock of the hanging member 104 at the non-hanging position, the hanging member 104 causes the balance weight 11 to move.
Since the linear member 1 is displaced upward so as to be pulled upward by 0, the linear member 1 is deformed into a wavy shape while being linearly attached to the linear member 104, as shown in FIGS. 1 and 21. The slack is absorbed. Since the cylinder 114 has a function of a damper that suppresses the wire hooking member 104 from being abruptly displaced upward by the balance weight 110, a large tension is not suddenly applied to the wire strut 1 and the wire straddle 1 is prevented. It is possible to prevent disconnection.

Further, as shown in FIG. 10, the slack absorbing means 100 has a tension detector (wire hooking) provided on the frame 108 for detecting the tension of the filament 1 hooked on the wire hooking member 104. Position detector) 118. The tension detector 118 includes a potentiometer 120 mounted on the frame 108 and a swing rod 102 for the potentiometer 1.
20 and a mechanical connector 122 for connecting to 20. In the illustrated embodiment, as shown in FIG. 10, the mechanical connector 122 includes a drive gear 124 held by a pivot shaft 102a (see FIG. 9) of a swing rod 102 supported by a bearing 106 and a drive gear 124 for driving the drive gear 124. It consists of a driven gear 126 that is meshed with a gear 124 and is held by an input shaft 120a of a potentiometer 120.

When the wire hanging member 104 hangs the wire rod 1 between the wire rod holding means 36 and the spooler 10 so that the looseness of the wire rod 1 is absorbed, the swing rod 102 swings. The drive gear 124 and the driven gear 126 are driven by the swing motion of the swing rod 102, and thus the potentiometer 12
0 generates a tension signal St that indicates the tension applied to the filament 1 between the filament clamping means 36 and the spooler 10A (see FIG. 1). This tension signal St is used to control the peripheral speed of the drive-side restraining roll 54 'so that the appropriate tension is applied to the linear body portion on the downstream side of the linear body clamping means 36. Therefore, the drive-side restraining roll 54 'of the linear member holding means 36 increases the peripheral speed when the tension of the downstream linear member is too high, and lowers the tension of the downstream linear member. When it passes, the peripheral speed is reduced to change the take-up speed.

The filament winding control device of the present invention is shown in FIG.
As shown in FIG.
Before releasing the wire from the non-wire hanging member,
Between the first spooler 10A and the upstream side of the linear body clamping means so as to maintain the linear body 1 in a position where it extends across the restraining rolls 54, 54 'to sandwich the linear body 1. Tension increasing means 128 (see FIG. 11 and FIG. 12) for applying a higher tension than the tension at the time of normal winding to the filament 1, and the first spooler 10A on the full winding side to the empty second spooler 1
When the filamentous body 1 is wound to the 0B side, the tension increasing means 128
After increasing the tension of the linear body 1, the slack absorbing means 100 is displaced from the non-lined position to the lined position, and the line-hanging member 104 of the slack absorbing means 100 contacts the linear body 1 to form the line-shaped body 1. Then, the tension increasing means 128, the slack absorbing means 100, and the filamentous body clamping means 3 are controlled so as to control the filamentous body clamping means 36.
6 is provided. FIG.
As can be seen from the above, the control means 130 controls the spooler 10
It also has a function of controlling so as to drive A and 10B.

In the illustrated embodiment, the tension increasing means 12
As shown in FIGS. 1, 11, and 12, the reference numeral 8 also serves as a tension adjusting means 132 in the form of a dancer provided on the upstream side of the filament shift mechanism 32. The tension adjusting means 132 is composed of a fixed dancer roller 134 and a movable dancer roller 136, and the movable dancer roller 136 is rotatable on one end of a lever-like swinging rod 140 pivotally supported on a frame 138 by a pivot shaft 140a. The balance weight 142 is provided at the other end of the swing rod 140. The filament 1 is wound around the fixed dancer roller 134 and the movable dancer roller 136 so that the movable dancer roller 136 is wound around the fixed dancer roller 134 and the movable dancer roller 136.
The winding tension of the filamentous body 1 is adjusted by displacing so as to maintain the tension determined by the masses of both 36 and the balance weight 142. This tension is set to about 50 g, for example.

As shown in FIG. 13, the tension adjusting means 132
Is a fixed dancer roller 134 and a movable dancer roller 136.
A variable dancer roller 136 for hanging the filament 1 on and
A rocking rod lifting mechanism 144 is provided for pushing up the air cylinder. The rocking rod lifting mechanism 144 is provided with an air cylinder 146 pivotally supported by the frame 138 and the air cylinder 14
6 is attached to the piston rod 146a of the swing rod 14
And a push-up bracket 148 that engages with zero.
When the linear member 1 is stretched over the tension adjusting means 132, the piston rod 146a of the air cylinder 146 is extended to make the swing rod 140 substantially horizontal by the push-up bracket 148, and the movable dancer roller 136 is fixed to the fixed dancer roller 13.
4, the filamentous body 1 is stretched between the dancer rollers 134 and 136.

As shown in FIG. 13, the push-up bracket 14
8 is normally in the position of FIG. 13 and the dancer roller 1
Since the movable dancer roller 136 is heavier than the balance weight 142 when the wire rods 34 and 136 are not hung on the wire or the filament body 1 is broken, the swing rod 140 swings clockwise in FIG. Be taken. The piston rod 146a of the air cylinder 146 is extended against the mass of the movable dancer roller 136 to move the swing rod 14
When the linear body 1 is lined up between the movable dancer roller 136 and the fixed dancer roller 134 with 0 being horizontal and the winding is started, the movable dancer roller 136 swings so as to maintain the tension determined by the mass of the balance weight 142 with respect to the movable dancer roller 136. Normally, the rod 140 is oscillated and displaced at or above the horizontal position, but at this time, the push-up bracket 148 causes the piston rod 146a of the air cylinder 146 to contract and the oscillating rod 1 to move.
It moves down to the position of FIG. When the movable dancer roller 136 suddenly descends due to the mass larger than the balance weight 142 due to the disconnection of the linear body 1, the swing rod 140 abuts the push-up bracket 148, and the air cylinder 146 acts as a damper at this time. .

As shown in FIGS. 11 and 12, the tension increasing means 128 is disposed on the side of the swinging rod 140 of the tension adjusting means 132 to which the balance weight 142 is attached so that the swinging rod 140 has the tension adjusting means 132. Tension adjusting means regulating mechanism 15 that regulates the tension adjusting function of the wire and applies a larger tension to the filament 1 than the tension determined by the balance weight 142.
Consists of zero.

More specifically, the tension adjusting means regulating mechanism 150, as shown in FIGS.
40 is oscillated to the side opposite to the tension adjusting side (normally a horizontal position or a position closer to the counterclockwise direction than that) against the balance weight 142 to move the oscillating rod 140 to a horizontal state or more. A roller-like rocking rod restricting member 152 is disposed at a position slightly offset in the clockwise direction (see FIG. 12) so as to move the variable dancer roller 136 to and from the rocking rod 140 so as to increase the tension of the linear body 1. And this rocking rod regulating member 1
And a cylinder 154 having a piston rod 154a for advancing and retracting (moving up and down) 52. This cylinder 15
As shown in FIG. 1, 4 is connected to a fluid source (not shown) via an electromagnetic control valve 156, and the electromagnetic control valve 156 controls the direction and amount of the fluid flowing into the cylinder 154 by the control means 130. . The tension increasing means 128 is set so that the tension acting on the filamentous body 1 is, for example, about 130 g.

As shown in FIGS. 13 and 14, the cylinder 154 is supported by an appropriate frame 158, and the swing rod restricting member 152 is normally provided by a tension spring 162 held by a frame 138 via a bracket 160. As shown in FIG. 11, it is urged to move away from the swinging rod 140. In this state, the swing rod 140 is released from the tension adjusting means regulating mechanism 150 and the winding weight of the filament 1 is adjusted by the balance weight 142 to be 50 g. On the other hand, as shown in FIG. 12, when the piston rod 154a of the cylinder 154 contracts, the rocking rod restricting member 152 moves the rocking rod 140 against the tension spring 162 in a horizontal state or slightly closer to the clockwise direction. While maintaining the above position, a large tension of 130 g is applied to the filament 1. As shown in FIG. 13, the movable guide 164 attached to the rocking rod restricting member 152 is fitted to the fixed guide 166 fixed to the bracket 160, and therefore, the rocking rod restricting member 152 includes these members. Guide 164,166
It is possible to move up and down stably. The tension spring 162 is stretched between the swinging rod restricting member 152 and the fixed guide 164. Also, as shown in FIG. 13, the piston rod 154a of the air cylinder 154 is also shown.
Are slidably guided in the fixed guide 168.

As shown in FIG. 15, tension adjusting means 132
Includes a tension detector 170, the tension detector 170
Comprises a potentiometer 172 which is directly connected to the pivot shaft 140a of the swing rod 140 and is rotationally driven according to the pivotal movement of the pivot shaft 140a. The tension detector 170 is used during normal winding to detect the winding tension and monitor whether the winding tension has a predetermined value.

As shown in FIG. 1, the control means 130 receives the shift signal Ss, the speed signal Sv indicating the actual value of the winding speed, and the tension detector (line-hook position detector) 118 of the slack absorbing means 100. The tension signal St is received, and the drive motor 48 of the filament shift mechanism 32, the spooler 10A,
10B drive motors 22A and 22B, a fluid control valve (not shown) for supplying fluid to the advancing / retreating cylinder 96 of the linear body clamping means 36, and a rotation motor 82 of the roll circumferential movement means 70.
And a solenoid controller 156 of the tension increasing means 128 and a programmer controller (PLC).

Next, the method of the present invention will be described in detail with reference to FIGS. 16 to 21. First, as shown in FIG.
Bobbin 12 with the first spooler (operating side spooler) 10A
When the linear body 1 is wound on A, the shift pulley 38 of the linear body shift mechanism 32 is near the spooler 10A, and the linear body 1 is wound on the bobbin 12A via the shift pulley 38. Has been. In such a normal winding state, in the tension adjusting means 132, the tension of the filament 1 and the balance weight 142 of the movable dancer roller 136 and the mass of the movable dancer roller 136 are increased.
The rocking rod 140 is rocked so as to be maintained at a value determined by the mass of, for example, 50 g.

In this case, the restraining rolls 54, 54 'of the linear member clamping means 36 are retracted as shown in FIG. 2, and the wire hooking member 104 of the slack absorbing means 100 is fixed to the locking air cylinder 114. By extending the piston rod 114a against the gravitational force of the balance weight 110, the piston rod 114a is locked in a non-lined position that is sufficiently retracted downward from the lined position (see FIG. 16B).

When the linear body 1 is fully wound around the bobbin 12A on the spooler 10A (actually before full winding, but in a state close to that), the linear body shift signal Ss as shown in FIG. Is input to the control means 130, and the control means 130
Is the shift pulley moving mechanism portion 4 of the linear body shift mechanism 32.
The drive motor 48 of No. 0 is driven to shift the shift pulley 38 to the position shown in FIG.
From the position 6 (A) to the position shown in FIG. 17 (A), the filamentous body 1 is continuously wound around the bobbin 12A on the first spooler 10A and shifted so as to straddle both spoolers 10A, 10B. Therefore, the filamentous body 1 has the structure shown in FIGS.
Bobbin 1 on the second spooler 10B as shown in (A)
The state corresponds to the inside of the driving side collar of 2B. In addition, when shifting the linear body 1 in this way, the linear body clamping means 3
As shown by the dotted line in FIG. 17, the restraining rollers 54 and 54 ′ of No. 6 are located at the position retracted from the passage through which the filamentous body 1 passes, so that the shifting of the filamentous body 1 is not hindered. Less than,
The restraining rollers 54, 54 ', shown in dotted lines in the various figures,
Means in the retracted position.

Next, as shown in FIGS. 4 and 5, the linear body 1 is on the bobbin 12A on the first spooler 10A on the operating side.
The operating side spooler 10A is advanced so that it is located inside the driving side collar of the bobbin 1 on the spooler 10A.
The terminal cover 24A is advanced by a cover advancing / retreating means (not shown) so as to cover the driving-side brim of 2A and the winding portion inside thereof. The empty bobbin 12B on the second spooler 10B on the standby side starts to rotate so that the peripheral speed of its body is synchronized with the winding speed of the filament 1, but the filament 1 is
Since it is not yet fixed to the bobbin 12B side, the linear body 1
Is not wound around the bobbin 12B.

After that, the control means 130 opens the electromagnetic control valve 150 in the cylinder contracting direction to operate the tension increasing means 128, and as shown in FIGS. 12 and 17, the tension increasing means 128 swing bar regulation. The member 146 is lifted up against the balance weight 142, and the swinging rod 140 of the tension adjusting means 132 is held at a position substantially horizontal in the direction in which the tension of the linear body 1 increases or slightly offset from it in the clockwise direction. To do.
Therefore, since the movable dancer roller 136 descends, the filament 1 is applied to the first spooler 10A by the tension of 50 g until now.
A higher tension is applied, for example 130 g.

In this way, after the tension of 130 g, which is higher than the normal winding tension, is applied to the filament 1, the piston rod 114a of the locking cylinder 114 (see FIG. 9) of the slack absorbing means 100 is shown in FIG. As shown in B), the weight of the balance weight 110 is applied to the swing rod 102 so that the line hooking member (looper member) 104 moves from the non-hooking position shown by the dotted line in FIG. 5 to the line shown by the solid line in FIG. Ascending toward the hanging position, as shown in FIG.
The filamentous body 1 which straddles A and 12B is hooked.

When the slack absorbing means 100 is released from the non-hooking position to the hooking position and the hooking member 104 hooks the wire body 1, the wire body 1 is already wound with a tension larger than 50 g. Since the tension of 130 g is applied, the filamentous body 1
Does not displace the linear member 1 by the wire hooking member 104 so as to hinder the forward movement of the pressing rollers 54, 54 'of the linear member clamping means 36. If only the normal winding tension of 50 g is applied when the filamentous member 1 is linearly attached to the linear hooking member 104, as shown in FIG. 22, the linear hooking member of the slack absorbing means 100. After the linear body 1 is hooked by 104, the linear body 1 is displaced upward so as to cross the position where the restraining roller 54 above the linear body sandwiching means 36 advances, and the linear body 1 is moved in a later step. When advancing the restraining rollers 54, 54 ′ across the ridges, the forward movement of the restraining rollers 54 is hindered, and the linear body 1 cannot be sandwiched between the restraining rollers 54, 54 ′.

After that, the driving of the rotary motor 60 of the filament holding means 36 is started to drive the driving side restraining roll 54 'out of the pair of restraining rolls 54, 54' at a speed higher than the winding speed of the filament 1. It is rotationally driven at a high speed (peripheral speed), the piston rod 96a of the advancing / retreating cylinder 96 of the roll advancing / retreating means 88 is extended, and the pair of restraining rolls 54, 54 'is advanced to the linear body sandwiching position (FIG. 4, FIG. (See FIGS. 5 and 19). The tension increasing means 128 does not prevent the restraining rolls 54 and 54 'from advancing to the linear body sandwiching position.
Has only the function of maintaining the extension roll extending between these restraining rolls 54, 54 ′, so that after the restraining rollers 54, 54 ′ have advanced to the striation clamping position, the piston of the air cylinder 154 is With the rod 154a in the extended state, the swinging rod restricting member 15 is moved by the tension spring 162.
2 may be separated from the oscillating rod 140 to return the filament 1 to the normal winding tension of 50 g. However, when the filament 1 is completely returned to the normal winding tension as described later, To the second
It may be after being wound around the spooler 10B side.

As already mentioned, the restraining rolls 54, 5
4'are still only facing each other with a small gap (about 5 mm) (see FIG. 19), so the pressing roll 5
Even if the filamentous body 1 is inserted between the restraining rolls 54, 54 'through the gap between the tapered portions 54a, 54'a (see FIG. 9) of 4, 54', the filamentous body 1 is still When it is not in a state of being sandwiched by the restraining rolls 54 and 54 ′, it receives the tension applied by the tension increasing means 128, passes through between the restraining rolls 54 and 54 ′, and passes through the line hanging member 104 of the slack absorbing means 100. While being wound on the bobbin 12A of the first spooler 10A.

In this way, the linear body 1 is restrained by the roll 5
8 ', the twin rod cylinder 56 of FIG. 8 is contracted to press the restraining roll 54 against the restraining roll 54' as shown in FIG. Drives the linear body 1 to hold both rollers 5
While being deformed into an S-shape so as to come into contact with the peripheral surfaces of 4, 54 ', they are sandwiched between these restraining rolls 54, 54'.
Therefore, the filament 1 tries to generate slack on the downstream side of the pressing rolls 54, 54 ', but since the filament 1 has already been hooked on the hooking member 104 of the slack absorbing means 100, this The displacement of the wire hanging member 104 absorbs the slack of the filament 1.

In this manner, the restraining rollers 54, 54 'of the linear member holding means 36 hold the linear member 1 to start the take-up action, and at the same time, the slack absorption amount of the linear member 1 swings.
As the rotation amount of the second pivot shaft 102a is transmitted to the potentiometer 120 of the tension detector 118 and the tension signal St is detected, and the tension signal St is supplied to the control means 130, the control means 130 causes the linear body. The take-up control start signal S so that a predetermined tension is maintained on the downstream side of the holding means 36.
b is supplied to the drive circuit of the rotation motor 60 of the restraining roller 54 'of the linear body clamping means 36 to adjust and control the peripheral speed (pulling speed) of the restraining roller 54'.

As will be described later, the restraining rolls 54 and 54 'have upstream tensions (usually 7 to 8) generated when the filamentous body 1 is caught and cut by the second spooler 10B in standby.
(kg) has a function of blocking so that it does not fall on the downstream side portion of the linear body 1. In addition, as shown in FIG. 4, the filamentous body 1 is led out from the notched opening 24Aa of the terminal cover 24A.

In this state, the line drawing rod 50, which is the line drawing body moving mechanism 34, is moved by the advancing / retreating cylinder 52 as shown in FIG. 6, and the line drawing body holding means 36 and the second spooler 1 are moved.
0B between the filament 1 and the capture member 28 of the spooler 10B
Close to B. Since the spooler 10B has already rotated at the same speed as the winding speed, the filament 1 is caught by the capturing member 28.
When it is brought close to B, the catch claw 26B becomes the catch member 28B.
When passing through the linear body 1 with the rotation of, the linear body 1 is captured between the capturing claw 26B and the disc-shaped capturing member 28B, and the linear body 1 is fixed to the spooler 10B side.

In this way, the filament 1 is captured by the capturing member 28.
When the capturing member 28B is captured between B and the capturing claw 26B, and the capturing member 28B further rotates, the pressing roll 5 of the linear body sandwiching means 36 is retained.
Since the tension of the filament 1 is further increased between 4, 54 'and the catching claw 26B, the filament 1 is finally torn off.
The filament 1 is subsequently continuously wound on the bobbin 12B on the spooler 10B. The tension when the filament 1 is thus torn off is large, for example, 7 to 8 kg, but this tension is transmitted to the spooler 10A side by the restraining rolls 54 and 54 'of the filament clamping means 36. Therefore, the quality of the striatum 1 on the bobbin 12A on the first spooler 10A is not deteriorated.

After the end (winding end terminal) of the linear body 1 torn off from the linear body 1 started to be wound on the bobbin 12B on the second spooler 10B is wound on the bobbin 12A on the first spooler 10A. The restraining roll 54 of the linear body sandwiching means 36 moves in the opposite direction from the position shown in FIG. 21 to the original position (the position shown in FIG. 20), so that the upper restraining roller 54 is spaced from the lower restraining roller 54 '. It is moved by the twin rod cylinder 56 so as to open, and then the roll advancing / retreating means 88 retracts the restraining rolls 54, 54 'from the linear body sandwiching position (see FIG. 2), and further the electromagnetic control valve 150 of the tension increasing means 128. The piston rod of the cylinder 148, which is supplied with the fluid in the opposite direction, is extended to swing the rod control member 146.
Is released from the swinging rod 140 so that the tension adjusting means 132 functions by the balance weight 142 and the locking cylinder 1 of the slack absorbing means 100.
The piston rod 114a of 14 is extended to prevent the balance eight 110 from working, and the slack absorbing means 100 is returned to the non-lined position and locked at this position.

The terminal cover 24A (see FIGS. 4 and 6) for covering the bobbin 12A has the end of winding of the linear body 1 wound by the bobbin 12A on the spooler 10A and stopped rotating. It is used to prevent the end-of-winding terminal from being violated by centrifugal force. After the rotation of the spooler 10A has stopped, the first bobbin 12A is removed from the spooler 10A and an empty bobbin is attached to prepare for the next winding.

As described above, the line-hanging member 104 of the slack absorbing means 100 contacts the line-shaped body 1 to be hung on the line-shaped body 1 before being caught by the restraining rollers 54, 54 'of the line-shaped body clamping means 36. Therefore, the restraining rollers 54, 54 ′ have the linear body 1.
At the same time that the slack absorbing means 10 is sandwiched by the control means 130.
When the pulling-up of the restraining roller 54 ′ is controlled based on the tension signal (line-hanging position detection signal) St from the tension detector (line-hanging position detector) 118 of 0, the tension detector 118 causes the linear body clamping means 36 to operate. Since the tension signal St corresponding to the actual tension on the downstream side of the line is generated, the restraining roller 54 'of the linear member clamping means 36 is not subject to erroneous pulling control based on the erroneous tension signal, and There is no excessive slack or excessive tension in the linear body 1 between the linear body shift mechanism 32 and the linear body holding means 36, and the linear body 1 can be rolled up. There is no failure.

Similarly, as described above, the linear member holding means 36 in the form of the restraining rollers (pinch rollers) 54, 54 'has a damping action and the restraining roll 5
The slack of the filamentous body 1 which is generated on the downstream side of 4, 54 'and absorbed by the slackness absorbing means 100 is caused by the filamentous body clamping means 36 on the filamentous body 1 on the first spool 12A on the fully wound side. It operates so as not to be adversely affected by excess tension applied to the upstream portion, so the spooler 10 that has been operated until now is
The linear body 1 on the spool 12A on A is the subsequent linear body 1
Will not be damaged or ruptured by the tension on the upstream side that occurs when is captured and cut by the second spooler 10B on the standby side.

In the illustrated embodiment, the linear body clamping means 3
6 includes a roll rotating means 70, and the pressing roll 5
Although the wire rod 1 is rotated around the axis of the roll 54 'so as to wind the filamentous body 1 into the S-shape, the roll rolling means 70 is not included, and the roll 54 is held by the roll 5.
4'may be simply opened and closed by opening and closing means such as a twin rod cylinder 56. Also in this case, the linear body 1 is moved from the spool 10A to the spool 10B.
After shifting to the side, the tension increasing means 128 applies a tension larger than the winding tension to the filament 1 to move the hanging member 104 of the slack absorbing means 100 from the non-hooking position to the hooking position. The lock is released so as to allow it, and then the holding roll 54 of the wire holding means 36 is closed by the holding roll 54 'to close the wire body 1 and at the same time hold the wire body 1 and wind it by driving the roller 54'. Collect at a speed faster than the speed. Subsequent operations are the same as those in the above-described embodiment having the roll moving means.

In the above embodiment, the tension increasing means 128
Functions to keep the striatum 1 extending across between the restraining rolls 54, 54 'so as not to prevent the restraining rolls 54, 54' from advancing to the striation clamping position. However, even if the wire hanging member 104 is released from the non-wire hanging position to displace the filament 1, the roll 5 can be suppressed.
The tension-increasing means 128 may be omitted if they are spaced so far apart from each other that their displacements do not hinder the advancement.

Another embodiment of the present invention is shown in FIG. 23 and subsequent figures. In this embodiment, as shown in FIGS. 24 and 25, the filament 1 is moved by the filament shift mechanism 32. After shifting the strip 1 from the first spooler 10A on the full-winding side to the second spooler 10B on standby, the pressing roller 54 'of the filament sandwiching means 36 is driven at a speed faster than the winding speed. , Both pressing rollers 54, 54 ′ are advanced to lower one pressing roller 54 so as to be in pressure contact with the other pressing roller 54 ′ (see FIG. 26), and at the same time, rotate around the other pressing roller 54. The linear body 1 is deformed into a state in which the linear body 1 is partially engaged with the peripheral surfaces of the two restraining rollers 54, 54 '(see FIG. 27).

Further, as shown in FIG. 27, the slack absorbing means 10 is provided at the same time that the linear body clamping means 36 clamps the linear body 1.
The wire hook member 104 of 0 is released from the non-wire hook position and the wire body 1 is hooked to the wire hook position where the slack is absorbed. In this case, the wire hooking member 104 rises as the swing rod 102 shown in FIG.
The potentiometer 120 generates a signal that changes in response to the raising of the hanging member 104. This signal is shown in FIG.
As shown in FIG. 3, the voltage value changes so as to increase as the position of the wire hanging member 104 rises, the linear member 1 comes into contact with the wire hanging member 104, and when the linear member 1 is linearly drawn, a small vibration occurs. And then settles down to a certain value.

The control means 130 receives the tension signal (signal indicating the line-hook position) of the tension detector (line-hook position detection means) 118, and the change of this signal per unit time becomes smaller than a predetermined value. At the time, that is, when the waveform of FIG.
Includes a determination circuit unit 174 that determines that the filamentous body 1 has been lined and generates a take-up control start signal Sb. When the determination circuit unit 162 generates the take-up control start signal Sb, the control unit 130 subsequently controls the pressing roller 54 ′ of the filament holding unit 36 based on the tension signal St of the tension detector 118.
Control the drive (take-back) of.

Also in the embodiment shown in FIG. 23 and subsequent figures, the tension detector 11 indicates that the wire hooking member 104 has wire-hanged the linear member 1.
Since the take-up control of the pressing roller 54 'is started after judging from the output of No. 8, the tension detector 118 detects the actual tension on the downstream side of the filamentous body clamping means 36 as in the previous embodiment. A corresponding tension signal St is supplied to the control means 130, so that the hold-down roller 54 'of the filament gripping means 36 is not subject to false pulling control on the basis of the false tension signal and thus the filament shift. Mechanism 32 and striation holding means 36
No excessive slack or excessive tension is generated in the filamentous body 1 and the filamentous body 1 does not fail in winding.

[0075]

As described above, according to the present invention, when the linear body is shifted from one spooler to the other spooler, the linear body is held by the rollers to absorb the slack on the downstream side. In order to control this slack, the amount of slack absorption is detected and the take-up of the suppressing roller is controlled based on this amount of slack absorption. Since it starts after contact, the filament does not loosen excessively or receive excessive tension on the upstream side of the position where the filament is sandwiched, and the winding of the filament fails. There is no.

When the linear member is hooked on the wire hooking member before the linear member is clamped, a tension higher than the normal winding tension is applied upstream of the position where the linear member is clamped. Since the linear member is hooked on the wire hooking member after the start, the wire member does not cross the pinching position of the holding roller by the wire hooking and hinders the movement of the holding roller to the pinching position. The body holding operation can be performed without interfering with each other.

Furthermore, when the tension detector for detecting the slack absorption amount detects the position of the hanging member to determine that the hanging member has drawn the filament, the pulling control of the restraining roller is started. The take-up control can be effectively carried out only by providing the filament winding device with a determination circuit section for determining the position of the wire hanging member.
