Description

Rotating tower type yarn winding device

Technical Field

The present invention relates to a turret type yarn winding device.

Background

Conventionally, there is known a so-called turret type yarn winding device in which a pair of main shafts are switched between a winding side and a standby side by rotating a turret so as to automatically and sequentially wind yarn members around bobbins provided on the main shafts.

Specifically, the turret type yarn winding device includes: the rotating tray is rotatably arranged on the shell; a plurality of main shafts which are arranged on the rotary tray in parallel in the axial direction and wind the yarn member on the installed bobbin by the rotation of the shafts; a traverse guide bar for evenly winding a yarn member around a bobbin of a main shaft mounted on a winding side while reciprocating in an axial direction of the main shaft between a first folded position on a distal end side of the main shaft and a second folded position on a base end side of the main shaft; and a holding mechanism which is provided in the main shaft and holds the yarn member of the traverse yarn guide at a predetermined holding position. Then, when the yarn member is wound around a spool mounted on a winding-side main shaft and the spool reaches a predetermined amount of yarn to be wound into a full bobbin state, the winding-side main shaft and a standby-side main shaft are switched to each other by rotating the turret, and the yarn member traversing the yarn guide bar is gripped by a gripping mechanism of a new winding-side main shaft, and then the yarn member is wound around the empty bobbin of the new winding-side main shaft. This allows the yarn member to be automatically wound on a plurality of bobbins in sequence.

Problems to be solved by the invention

However, when the spool reaches a predetermined amount of yarn winding and becomes a full bobbin state and the turret is rotated to switch the winding-side spindle and the standby-side spindle from each other, the position of the traverse guide is random depending on the timing, and therefore, the predetermined time for the traverse guide to reach the holding position differs. Therefore, the following problems occur: variations occur in the quality of the yarn winding amount, the yarn winding shape, and the like of the yarn winding body in which the yarn member is wound around the spool.

In particular, when the traverse guide reaches the holding position of the yarn member after the switching between the winding-side spindle and the standby-side spindle is completed, the time for starting winding the yarn member around the empty bobbin in the new winding-side spindle is delayed, which may cause a problem of a decrease in the productivity of the yarn package.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a yarn winding device capable of efficiently producing a yarn winding body of stable quality.

Means for solving the problems

In order to achieve the above object, the present invention provides a turret type yarn winding device including: the rotating tray is rotatably arranged on the shell; a plurality of spindles which are arranged in parallel in the axial direction on the rotating tray and wind the yarn member around the installed bobbin by rotating the spindles; a traverse guide bar that evenly winds a yarn member around a bobbin of the main shaft mounted on a winding side while reciprocating in an axial direction of the main shaft between a first folded position on a distal end portion side of the main shaft and a second folded position on a base end portion side of the main shaft; a holding mechanism which is provided in the main shaft and holds a yarn member which is successively drawn out from the traverse guide at a predetermined holding position; and a control unit for controlling the rotation of the turret disc, the rotation of the spindle, the reciprocating movement of the traverse yarn guide bar, and the holding of the yarn member by the holding mechanism; the turret type yarn winding device is characterized in that the control unit calculates a moving speed and/or a moving path of the traverse guide bar based on a switching time between the main shaft on the winding side and the main shaft on the standby machine side when the yarn member mounted on the bobbin on the winding side reaches a predetermined amount of yarn to be brought into a full state, and moves the traverse guide bar at the moving speed and/or the moving path so that the traverse guide bar reaches a holding position of the yarn member when the switching between the main shaft on the winding side and the main shaft on the standby machine side is completed.

According to the present invention, since the traverse guide reaches the holding position of the yarn member when the switching between the main shaft on the winding side and the main shaft on the standby side is completed, the time taken for the traverse guide to reach the holding position can be unified, and variations in quality such as the amount of yarn wound on the yarn winding body of the spool and the shape of the wound yarn can be reduced or prevented. Further, the traverse guide does not reach the holding position of the yarn member after the switching between the main shaft on the winding side and the main shaft on the standby side is completed, the winding of the yarn member can be started quickly, and the production efficiency of the yarn winding body can be improved.

The control unit may calculate a switching time between the main shaft on the winding side and the main shaft on the standby side based on a winding position of the main shaft on the winding side at the winding end, a standby position of the main shaft on the standby side at the winding start, and a rotation speed of the turret disc when a yarn member mounted on a bobbin of the main shaft on the winding side reaches a predetermined yarn winding amount and becomes a full bobbin state. Thus, even when the winding position phase of the winding-side main shaft is advanced due to an increase in the diameter of the yarn winding body as the yarn member is wound, the switching time between the winding-side main shaft and the standby-side main shaft can be reliably calculated.

The control section may move the traverse guide at a fixed speed between a predetermined distance immediately before the yarn member of the traverse guide is gripped by the gripping mechanism. Thus, the yarn member can be prevented from being gathered due to a slow moving speed of the traverse guide or from being wound to the outside due to a fast moving speed, and the yarn member can be stably wound on the bobbin to the end.

The control section may calculate a movement path along which the traverse yarn guide bar moves to the gripping position of the yarn member at a predetermined movement speed when the traverse yarn guide bar moves in a direction approaching the gripping position of the yarn member when the yarn member mounted on the bobbin of the main shaft on the winding side reaches a predetermined yarn winding amount and becomes a full bobbin state. Thus, the traverse guide can be moved to the yarn member holding position as it is.

The control unit may move the traverse guide bar to the first folded position at a predetermined moving speed and turn back at the first folded position, and then move the traverse guide bar to the yarn member holding position at a predetermined moving speed when the traverse guide bar moves in a direction away from the yarn member holding position when the yarn member on the spool mounted on the winding-side main shaft reaches a predetermined yarn winding amount and becomes a full bobbin state. Thus, the traverse guide can be moved to the holding position of the yarn member after being folded at the first folding position in the same manner as in a general traverse.

The control section may calculate a movement path in which the traverse yarn guide bar is folded back in a direction approaching a holding position of the yarn member together with rotation of the turret disc and is moved to the holding position of the yarn member at a predetermined movement speed when the traverse yarn guide bar is moved in a direction away from the holding position of the yarn member when the yarn member mounted on the bobbin of the main shaft on the winding side reaches a predetermined yarn winding amount and is in a full bobbin state. Accordingly, the traverse guide bar is folded back in a direction approaching the holding position simultaneously with the rotation of the turret disk, and therefore the traverse guide bar can be quickly moved to the holding position of the yarn member.

The control unit may calculate a movement path of the traverse guide bar which moves to the second returning position at a predetermined movement speed and which is turned back at the second returning position when the traverse guide bar moves between the predetermined shift position and the second returning position in a direction approaching the holding position of the yarn member when the yarn member on the spool mounted on the main shaft on the winding side reaches a predetermined yarn winding amount and becomes a full bobbin state. Thus, even if the traverse guide moves in a direction approaching the holding position of the yarn member across the shift position for changing the moving speed, the traverse guide is folded back at the second folding position as it is, and the moving speed can be changed after the traverse guide reaches the shift position.

The control unit may calculate a movement path of the traverse guide rod that is folded back at a third folding position set between the first folding position and the second folding position and moves in a direction approaching a gripping position of the yarn member when the yarn member on the spool mounted on the main shaft on the winding side reaches a predetermined amount of yarn winding and becomes a full bobbin state. Thus, the traverse guide bar is folded at the third folding position during movement and is moved in a direction approaching the holding position of the yarn member, so that the traverse guide bar can be quickly moved to the holding position of the yarn member.

Effects of the invention

According to the present invention, since the traverse guide reaches the holding position of the yarn member when the switching between the main shaft on the winding side and the main shaft on the standby side is completed, it is possible to equalize the time taken for the traverse guide to reach the holding position, and it is possible to reduce or prevent variations in quality such as the amount of yarn wound on the yarn winding body of the yarn member wound on the spool, the shape of the wound yarn, and the like. Further, the traverse guide does not reach the holding position of the yarn member after the switching between the main shaft on the winding side and the main shaft on the standby side is completed, the winding of the yarn member can be started quickly, and the production efficiency of the yarn winding body can be improved.

Detailed Description

Next, an embodiment of a turret type yarn winding device (hereinafter referred to as the present device) according to the present invention will be described with reference to the drawings.

As shown in fig. 1, the present apparatus includes: a housing 10; the rotating tray 1 is arranged on the shell 10; a pair of spindles 2 provided on the turret disk 1; and a traverse mechanism 3 provided in the housing.

In fig. 1, (12) is a guide roller for guiding the yarn member L to the traverse mechanism 3, and a plurality of additional guide rollers may be provided between the guide roller 12 and the traverse mechanism 3. Further, (35) is a pressure contact roller which is pressed against the wound body M of the yarn member L in the bobbin 21 of the spindle 2.

The rotating tray 1 is a disk rotatably provided on the front surface side of the casing 10, supported by four rollers 11 provided around the rotating tray, and supported by the casing 10 at the center portion of the rear surface thereof, and rotated in the planar direction by a drive motor, not shown, provided inside the casing 10 on the rear surface side.

The main shaft 2 is provided so as to vertically protrude from the front surface side of the turret disk 1, and is rotated by a not-shown drive motor provided on the rear surface side of the turret disk 1.

A bobbin 21 having a circular tube shape is detachably attached to the spindle 2 in the axial direction, and the yarn member L is wound around the bobbin 21 as the spindle rotates.

The main shaft 2 is provided with a gripping mechanism 22 at a base end portion thereof for gripping the yarn member L, and grips the yarn member L, which is fed out from a traverse guide 32 described later, when the yarn member L starts to be wound around the bobbin 21 on a predetermined winding side. In the present embodiment, as shown in fig. 2, the gripping mechanism 22 is openably and closably provided at the base end portion of the main shaft 2, opens in the axial direction of the main shaft 2 and guides the yarn member L by a command of the control unit 4 to be described later, and then closes in the axial direction of the main shaft 2 and grips the yarn member L.

The spindles 2 are arranged on the turret disc 1 at a phase difference of 180 degrees from each other, and are switched by the rotation of the turret disc 1 between the spindle 2 on the winding side for winding the yarn member L and the spindle 2 on the standby side for attaching and detaching and waiting the bobbin 21.

The traverse mechanism 3 is provided in the vicinity of the winding-side main shaft 2, and as shown in fig. 3, includes: a traverse body 31; and a traverse guide bar 32 provided in the traverse body 31.

The traverse guide 32 is reciprocally moved along the axial direction of the main shaft 2 between a first returning position a on the front end portion side of the main shaft 2 and a second returning position B on the base end portion side of the main shaft 2 while being spaced apart from the main shaft 2 on the winding side by a predetermined distance by a drive motor, not shown, provided in the housing 10.

In the present embodiment, the second returning position B is set as the holding position H of the yarn member L when the winding of the yarn member L is started. The position of the traverse guide 32 is measured by the degree of rotation of the drive motor of the traverse guide 32.

In fig. 3, (33) is a sensor for detecting a reference (origin) for switching of the yarn member L, and (34) is a sensor for detecting the yarn member L when the yarn member L is held.

Then, in this apparatus, as shown in fig. 5 (a), the yarn member L is wound around the bobbin 21 of the main shaft 2 mounted on the winding side (left side), and when the bobbin 21 reaches a predetermined yarn winding amount and becomes a full bobbin state, as shown in fig. 5 (b), the main shaft 2 on the winding side (left side) and the main shaft 2 on the standby side (right side) are switched with each other by the rotation of the rotating tray 1. Then, as shown in fig. 5 (c), after the yarn member L of the traverse guide 32 is gripped by the gripping mechanism 22 of the main shaft 2 on the winding side (left side) after the changeover, the yarn member L between the main shaft 2 on the winding side (left side) and the main shaft 2 on the standby side (right side) is cut off, and the yarn member L is continuously wound around the bobbin 21 in the empty state of the main shaft 2 on the winding side (left side) after the changeover. Then, the spool 21 in the full bobbin state is removed from the spindle 2 on the standby side (right side), and the spool 21 in the empty state is mounted. By repeating this series of operations, the yarn members L can be sequentially wound around the bobbin 21 of the spindle 2.

The rotation of the rotating tray 1, the axial rotation of the main shaft 2, the reciprocating movement of the traverse yarn guide 32, and the holding of the yarn member L by the holding mechanism 22 are controlled by the control section 4 as shown in fig. 4.

When the switching between the winding-side main shaft 2 and the standby-side main shaft 2 is completed, the control section 4 controls the traverse guide 32 to reach the holding position H of the yarn member L. Specifically, as shown in fig. 5 (b) and (c), after the yarn member L of the bobbin 21 mounted on the main shaft 2 at the winding position θ 0 at the start of winding reaches a predetermined amount of yarn to be in the full bobbin state, the main shaft 2 in the full bobbin state is switched from the winding position θ 1 at the end of winding to the standby position θ 2 at the start of winding, the main shaft 2 in the empty bobbin state is switched from the standby position (θ 1+180 °) at the end of winding to the winding position θ 0 at the start of winding, and when the above operation is finished, the control section 4 moves the traverse guide lever 32 at a predetermined moving speed and/or moving path so that the traverse guide lever 32 randomly positioned on the traverse mechanism 3 reaches the holding position H of the yarn member L. In the calculation of the moving speed and/or the moving path of the traverse guide bar 32, when the yarn member L of the bobbin 21 mounted on the main shaft 2 at the winding position θ 1 at the winding end reaches a predetermined yarn winding amount and becomes a full bobbin state (between the time when the control section 4 receives a full bobbin signal and the start of rotation of the turret disc 1), the control section 4 calculates the moving speed and/or the moving path of the traverse guide bar 32 based on the switching time between the main shaft 2 on the winding side and the main shaft 2 on the standby side by the rotation of the turret disc 1.

In the present embodiment, the control section 4 calculates the switching time t between the main shaft 2 on the winding side and the main shaft 2 on the standby side by the rotation of the turret disk 1 by the following equation.

t＝(θ2－θ1)/ω…[1]

θ 1: winding position (angle) of the spindle 2 at the end of winding

θ 2: standby position (angle) of spindle 2 at the start of winding

ω: angular velocity of rotating disc

Further, since the diameter of the wound yarn body M is increased by winding the yarn member L, the winding position θ 1 of the main shaft 2 at the time of ending the winding is advanced to the right (θ 1 — θ 0) phase with respect to the predetermined winding position θ 0 at the time of starting the winding. Therefore, the control section 4 measures the winding position θ 1 of the main shaft 2 at the time of finishing the winding based on the degree of rotation of the turret plate 1 (drive motor). The winding position θ 0 and the standby position θ 2 of the spindle 2 at the start of winding are set in advance. In addition, the angular velocity ω of the rotating disk is also set in advance.

An example of calculating the moving speed and/or the moving path of the traverse guide 32 will be described below. In the following calculation examples, the moving speeds V1 and V2 and the positions L0 to L4 and Ltr of the traverse guide 32 are defined as follows.

V1: first moving speed of the traverse guide bar 32

V2: second moving speed (fixed) of the traverse yarn guide 32

L0: the first turning position A (origin) of the traverse guide bar 32 on the front end side of the main shaft 2

L1: the position of the traverse yarn guide 32 when the winding spindle 2 is fully wound

L2: switching position of moving speed of traverse yarn guide 32

L3: shift position (same position as L2 or L0 side position) capable of changing moving speed

L4: preset third turning position C

Ltr: a second returning position B (the same position as the holding position H of the yarn member L in the present embodiment) on the base end side of the main shaft 2 of the traverse guide bar 32

< calculation example 1 >

When the yarn member L of the bobbin 21 attached to the winding-side spindle 2 reaches a predetermined amount of yarn winding and is in the full bobbin state, as shown in fig. 6 (a), when the traverse guide lever 32 moves between the position L0 and the position L1 in a direction approaching the position Ltr, the control section 4 calculates a movement path along which the traverse guide lever 32 moves from the position L1 to the position Ltr (the holding position H of the yarn member L) at the first movement speed V1. At this time, the control unit 4 calculates the first moving speed V1 by the following expression [2 ].

V1＝(Ltr－L1)/t…[2]

< calculation example 2 >

When the yarn member L of the bobbin 21 attached to the winding-side spindle 2 reaches a predetermined amount of yarn winding and is in the full bobbin state, as shown in fig. 6 (b), when the traverse guide bar 32 moves between the position L0 and the position Ltr in the direction away from the position Ltr, the control section 4 calculates a movement path along which the traverse guide bar 32 moves from the position L1 to the position L0 at the first movement speed V1, turns back at the position L0 (first turning position a), and then moves from the position L0 to the position Ltr (holding position H of the yarn member L) at the first movement speed V1. At this time, the controller 4 calculates the first moving speed V1 by the following expression [3 ].

(L1－L0)/V1+(Ltr－L0)/V1＝t…[3]

< calculation example 3 >

When the yarn member L of the bobbin 21 attached to the winding-side spindle 2 reaches a predetermined amount of yarn to be wound and is in the full bobbin state, as shown in fig. 6 (c), when the traverse guide bar 32 moves between the position L0 and the position L2 in the direction approaching the position Ltr, the control section 4 calculates a movement path in which the traverse guide bar 32 moves from the position L1 to the position L2 at the first movement speed V1 and then moves (is fixed) from the position L2 to the position Ltr (the holding position H of the yarn member L) at the second movement speed V2. At this time, the control unit 4 calculates the first moving speed V1 by the following expression [4 ].

(L2－L1)/V1+(Ltr－L2)/V2＝t…[4]

< calculation example 4 >

When the yarn member L on the bobbin 21 mounted on the main shaft 2 on the winding side reaches a predetermined yarn winding amount and becomes in the full bobbin state, as shown in fig. 6 (d), when the traverse guide bar 32 moves in the direction away from the position Ltr between the position L0 and the position L2, the control section 4 calculates a movement path in which the traverse guide bar 32 moves from the position L1 to the position L0 at the first movement speed V1, turns back at the position L0 (first turning position a), moves from the position L0 to the position L2 at the first movement speed V1, and moves from the position L2 to the position Ltr (holding position H of the yarn member L) at the second movement speed V2 (fixed). At this time, the control unit 4 calculates the first moving speed V1 by the following expression [5 ].

(L1－L0)/V1+(L2－L0)/V1+(Ltr－L2)/V2＝t…[5]

< calculation example 5 >

When the yarn member L on the bobbin 21 of the main shaft 2 on the winding side reaches a predetermined amount of yarn to be wound and becomes in the full bobbin state, as shown in fig. 7 (a), when the traverse guide bar 32 moves between the position L0 and the position L2 in the direction away from the position Ltr, the control section 4 calculates a movement path in which the traverse guide bar 32 turns back in the direction approaching the position Ltr at the position L1 while rotating with the turret disc 1, moves from the position L1 to the position L2 at the first movement speed V1, and moves from the position L2 to the position Ltr (the holding position H of the yarn member L) at the second movement speed V2 (fixed). At this time, the control unit 4 calculates the first moving speed V1 by the following expression [6 ].

(L2－L1)/V1+(Ltr－L2)/V2＝t…[6]

< calculation example 6 >

When the yarn member L of the bobbin 21 attached to the winding-side spindle 2 reaches a predetermined amount of yarn winding and is in the full bobbin state, as shown in fig. 7 (B), when the traverse guide bar 32 moves between the position L3 (shift position) and the position L2 in a direction approaching the position Ltr, the control section 4 calculates a movement path in which the traverse guide bar 32 moves from the position L1 to the position Ltr at the first movement speed V1 and is folded back at the position Ltr (second folded-back position B), then moves from the position Ltr to the position L0 at the first movement speed V1 and is folded back at the position L0 (first folded-back position a), then moves from the position L0 to the position L2 at the first movement speed V1 and moves from the position L2 to the position Ltr (gripping position H of the yarn member L) at the second movement speed V2 (fixed). At this time, the control unit 4 calculates the first moving speed V1 by the following expression [7 ].

(Ltr－L1)/V1+(Ltr－L0)/V1+(L2－L0)/V1+(Ltr－L2)/V2＝t…[7]

< calculation example 7 >

When the yarn member L on the bobbin 21 of the main shaft 2 on the winding side reaches a predetermined amount of yarn to be wound and is in the full bobbin state, as shown in fig. 7 (C), when the traverse guide lever 32 moves between the position L3 and the position L2 in a direction approaching the position Ltr, the control section 4 calculates a movement path in which the traverse guide lever 32 moves from the position L1 to the position Ltr at the first movement speed V1 and is folded back at the position Ltr (second folding position B), then moves from the position Ltr to the position L4 at the first movement speed V1 and is folded back at the position L4 (third folding position C), and then moves from the position L4 to the position L2 at the first movement speed V1 and moves from the position L2 to the position Ltr (gripping position H of the yarn member L) at the second movement speed V2. At this time, the control unit 4 calculates the first moving speed V1 by the following expression [8 ].

(Ltr－L1)/V1+(Ltr－L4)/V1+(L2－L4)/V1+(Ltr－L2)/V2＝t…[8]

In this way, since the traverse guide bar 32 reaches the holding position H of the yarn member L when the switching between the main shaft 2 on the winding side and the main shaft 2 on the standby side is completed, it is possible to make the timing for the traverse guide bar 32 to reach the holding position H uniform, and to reduce or prevent variations in the quality such as the amount of the wound yarn or the shape of the wound yarn of the wound body M in which the yarn member L is wound on the bobbin 21. Further, the traverse guide bar 32 does not reach the holding position H of the yarn member L after the switching between the main shaft 2 on the winding side and the main shaft 2 on the standby side is completed, and the winding of the yarn member L can be started quickly, and the productivity of the yarn package M can be improved.

In the present embodiment, although the above-described calculation examples 1 to 7 are illustrated, the present invention is not limited to the above-described movement path and movement speed. In short, the traverse guide 32 may have any movement path and movement speed as long as it reaches the holding position H of the yarn member L when the switching between the winding-side main shaft 2 and the standby-side main shaft 2 is completed.

Further, the holding position H as the yarn member L is set at the second returning position B, but may be set at a position different from the second returning position B, for example, a position between the second returning position B and the housing 10.

The control unit 4 calculates the switching time between the winding-side spindle 2 and the standby-side spindle 2 based on the above expression [1], but may calculate or use a previously calculated switching time by another calculation expression.

The winding-side main shaft 2 advances to the right phase according to the degree of winding of the yarn member L, but may be maintained at the winding position θ 0 at the start of winding from the start of winding to the end of winding.

The above expressions [2] to [8] are not limited to the forms of the above expressions, and may be forms in which V1 is directly calculated or other forms.

Further, the traverse of the traverse guide bar 32 of the traverse mechanism 3 has been described in which the yarn member L is wound around the bobbin 21 while the turn-back position is fixed, but the yarn member L may be wound around the bobbin 21 while the turn-back position is changed according to the winding diameter of the yarn winding body M.

Further, the control section 4 calculates the moving speed and the moving path of the traverse guide bar 32 based on the switching time between the main shaft 2 on the winding side and the main shaft 2 on the standby side, but may calculate only the moving speed of the traverse guide bar 32 or only the moving path of the traverse guide bar 32.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. The embodiments shown in the drawings may be modified or changed in various ways within the same scope as the present invention or within the equivalent scope.
