Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traverse device for traversing a running yarn in the axial direction of a bobbin, and more particularly to a belt wound around a driving wheel and a driven wheel. The present invention relates to a traverse device comprising a traverse guide attached to an endless swivel band.

[0002]

2. Description of the Related Art A traverse device utilizing an endless rotating band used in a yarn winding mechanism of a draw false twister uses a yarn guided by a traverse guide by repetitive forward and reverse driving of a driving wheel body. One that traverses the strip in the axial direction of the bobbin is used. As shown in Japanese Patent Application Laid-Open No. 10-250938, this type of traverse device is provided with a tension mechanism such as a roller that tensions an endless rotating band.

[0003] That is, the endless rotating belt such as a belt and a wire is stretched with the use of the traverse device.
By absorbing the elongation by the tension mechanism, it is possible to perform a good traverse without displacement. In this case, in a general structure in which the tension roller is simply pulled and urged by an elastic member such as a spring, the tension roller relatively easily moves in the tension direction due to the tension fluctuation of the endless rotation band due to a driving force, a load fluctuation, and the like. There is a possibility that the movement of the traverse guide becomes jerky and non-smooth due to the endless rotation band fluttering.

Therefore, as shown in Japanese Patent Application Laid-Open No. Hei 5-107827, bolts and nuts for fixing and maintaining a tension sprocket pulled and urged by a winding spring are provided to eliminate play of the endless rotating band. By applying technology that can fix tension sprockets to the traverse device,
It is conceivable to eliminate the fluttering of the endless rotating band during the operation due to the movable state of the tension roller, so that the traverse guide can be smoothly traversed.

[0005]

However, the operation of maintaining and fixing the tension roller by means of bolts and nuts and the fixing and maintaining of the tension roller in order to apply a tension urging force to the tension roller in order to absorb the slack of the endless rotating band. Is a manual operation that must be performed by the operator as appropriate, so that the operation is troublesome and the possibility of inconvenience due to forgetting the operation can be predicted. Therefore, there is room for improvement in operability.

Therefore, as shown in Japanese Patent Application Laid-Open No. 4-129775, by using the ratchet mechanism in a state in which the ratchet mechanism acts in the opposite direction, it is possible to prevent the unreasonable pulling force from acting and to prevent the endless turning band from being applied. By applying a technique in which the tension is periodically increased and renewed in accordance with elongation to a traverse device, a means for automatically adjusting the tension without human operation was considered. .

However, in the means that can be called an inverted ratchet mechanism, the driving ratchet and the driven ratchet that come into contact with each other on the inclined surfaces press the driving ratchet against the driven ratchet by a helical spring, and the elastic force is generated. Thus, the tension roller is balanced with the tension to maintain the position of the tension roller, that is, the tension roller is locked and maintained, but not completely fixed. When the tension acts, the tension roller cannot move and flutter, so that there is room for further improvement.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the tension of the endless rotating band periodically while fixing the tensioning ring in the appropriate tension state to suppress the endless rotating band from fluttering. A traverse device capable of exhibiting a traverse function is realized without troublesome manual operation.

[0009]

According to a first aspect of the present invention, a traverse guide is mounted on an endless rotating band wound around a driving wheel body and a driven wheel body, and the driving wheel body is driven forward and reverse. In the traverse device provided with a tensioning mechanism for traversing the yarn guided by the traverse guide in the axial direction of the bobbin and for tensioning the endless rotation band, the tensioning mechanism is rotated by the endless rotation. A tension member that contacts the band, and a tension applying member that urges the tension member in the tensioning direction of the endless rotating band, and adjusts the position of the tension member against the urging force of the tension applying member. In addition to providing a locking mechanism that can be fixed and released freely, the locking and fixing of the tension member is temporarily released at set time intervals, and otherwise the tension member is locked and fixed, Wherein the is provided an association operation means for operating the Kigakaritome mechanism.

According to the first aspect of the present invention, the tension member for urging the endless rotation band by the urging force of the tension applying member, and the position of the tension member is fixed and fixed in the state of urging the endless rotation band. Since the tension member is locked and fixed in a state where the endless turning band is normally urged by providing a locking mechanism that can be freely released, the endless turning band without slack is moved in and out of the loop. Thus, a state in which the traverse operation is performed without swinging or flapping can be obtained, and the traverse operation can be favorably performed.

The function of the linking operation means temporarily releases the locking and fixing of the tension member, and the state in which the tension of the endless rotating band by the tension member, which is called the additional tension, is updated periodically. The slack of the endless swivel band due to the continuous fixing of the tension member is absorbed, and the endless swivel band is appropriately tensioned to maintain the slack-free state automatically. Will be performed.

According to a second aspect of the present invention, in the first aspect, a doffing device is provided for taking out a full-wound package, which is fully wound while the yarn is traversed on the bobbin, from a winding mechanism so as to move to the next step. With the doffing device, the locking and fixing of the tension member is released along with the unloading operation of the full winding package, and the doffing device is locked so that the tension member is locked and fixed when the doffing device is not operated. By providing an interlocking member that interlocks with the mechanism,
It is characterized in that link operation means is configured.

According to the second aspect of the present invention, when the yarn is fully wound around the bobbin using the traverse device, the doffing device operates to take out the fully wound package for the next step and to start a new winding. A series of operations in which the next bobbin is set as an object to be picked up is used as a link operation means. That is, by using the doffing device that is temporarily activated in winding the yarn, the locking and fixing of the tension member is temporarily released by the operation of the doffing device, and the doffing device does not operate. Sometimes, the tension member is locked and fixed. or,
Since the linking operation means can be constituted by the existing equipment, a dedicated linking operation means is not required.

According to a third aspect of the present invention, in the first or second aspect, the locking mechanism includes a resilient member for pressing and fixing the tension member to the device fixing portion and locking the tension member. A switching member is provided for switching between a fixed state in which the urging force of the member acts on the tension member to lock and fix the position of the tension member and a release state in which the locking and fixing of the tension member by the urging force of the elastic member is released. It is characterized by being constituted.

According to the third aspect of the present invention, the tension member is pressed by the resilient member, so that the tension member can be fixed by friction holding. Since it is fixed by friction holding, it is possible to retrofit existing equipment.

According to a fourth aspect of the present invention, in the first to third aspects, the tension member is a driving wheel having a driving motor.

According to the configuration of the fourth aspect, since there is no dedicated ring for tension, the structure can be simplified in that respect, and the drive motor, which is also the vibration source, is used as a member for tensioning the endless rotating band. Since it is fixed, the endless rotation band, that is, the swinging motion of the traverse guide during driving as the traverse device is further reduced, and a good traverse action can be obtained.

The drive pulley (an example of a tension member) 23 is configured to be locked and fixed and can be freely released against the urging force of the winding springs (an example of the elastic member) 35, 35. Then, as will be described later, the interlocking wire 52 operates the locking mechanism K such that the locking and fixing of the driving pulley 23 is temporarily released at set time intervals, and otherwise the driving pulley 23 is locked and fixed. It functions as an example of the link operation means R. In a state where the driving pulley 23 is locked and fixed by the locking mechanism K, the position of the driving pulley 23 cannot be changed with respect to the frame plate 34,

That is, since the tension winding spring 51 strongly pulls the fulcrum shaft 49 toward the bracket 60 (left side in FIG. 4), the upper and lower crank arms 47, 48 are provided.
The waist-break link consisting of
The buckling link is moved relatively downward with respect to the upper frame member 34A. As a result, the pressing plate 50 pressed by the lower crank arm 48 presses the slide plate 33 against the frame plate 34, and the winding spring 35 , 35, the slide plate 33 is locked and fixed by frictional force.

When the yarn Y is fully wound on the bobbin B, the autodoffer 1 operates to take out the fully wound package P into the stocker 32, and the cradle arm 18 rises and swings to pull the interlocking wire 52 greatly. Then, the accommodation mechanism 5
5, the interlocking wire 52 is pulled beyond the operating area of the fulcrum shaft 4 against the urging force of the tension winding spring 51.
9 is moved to the support member 57 side (the right side in FIG. 4), the pressing action by the pressing plate 50 is released, and as shown in FIG. 6, a belt tension state in which the slide plate 33 becomes slidable appears. .

In this state, a pair of winding springs 35, 35
Since the urging force can act on the slide plate 33, if the belt 24 is slacked at that time, the slack is eliminated and the action of appropriately tensioning the belt 24 is performed instantaneously. When the package P is doffed and the raised cradle arm 18 swings downward to set the next empty bobbin B in the winding mechanism 30, the pulling action of the fulcrum shaft 49 by the interlocking wire 52 is released. 4, the tension winding spring 51 pulls the fulcrum shaft 49, the lower crank arm 48 strongly presses the slide plate 33 against the frame plate 34 via the pressing plate 50, and locks and fixes the position of the drive pulley 23 again as shown in FIG. The fixed position state appears.

Incidentally, as the winding of the yarn Y onto the bobbin B progresses, the winding diameter increases and the cradle arm 18
Gradually rises and swings. However, at the position of the cradle arm 18 when the cradle arm 18 is fully wound, the cradle arm 18 is within the operation area of the accommodating mechanism 55, and the interlocking wire 52 has not been pulled yet.

That is, the locking and fixing of the slide plate 33 is temporarily released each time the doffing operation is performed, and the driving pulley 23 is urged to tension the belt 24. In other cases, the tension is applied. In this state, the slide plate 33 is locked and fixed so as not to move, so that the tension of the belt 24 is updated each time the doffing operation is performed.

That is, by moving the drive pulley 23 together with the slide plate 33 to the upstream side in the yarn running direction in FIG. 4, the tension of the belt 24 is updated, and the display rod attached to the slide plate 33 is moved with the movement. 41 moves in the protruding direction. The amount of protrusion of the display rod 41 changes according to the amount of extension of the belt 24. The replacement time of the belt 24 can be recognized by visually confirming the amount of protrusion of the display rod 41.
