Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a position adjustment mechanism for a yarn guide for an auxiliary guide roller in a yarn winding machine.

B. Prior Art A conventional yarn winding machine in which a waist is wound around an auxiliary roller during doffing is shown in Figs.
As shown in the figure, each machine has one winding bobbin, so-called single bobbin type, or two bobbin types, and even in the double bobbin type, the position of the bobbin B on the winding side is fixed by rotating the turret to which the collet is attached by 180 degrees. In these types, the auxiliary roller 7 is in a position off the collet axis (Fig. 5b) during winding of the yarn Y, but when winding onto the winding bobbin B is completed, the auxiliary roller arm 21 swings around the arm axis 22, and the auxiliary roller 7 is moved to the axis of the winding bobbin B (Fig. 5a). Then, the auxiliary roller 7 is moved to the bobbin B side as shown by the arrow M by the operation of a piston cylinder (not shown), and while rotating, its tip is inserted into the front cap 20. Next, the auxiliary roller yarn guide 9 installed adjacent to the auxiliary roller 7 is operated to rotate its guide rod 9a by 90 degrees in a horizontal plane. By this rotation, the yarn Y, which has been pushed by the winding side yarn guide bar (not shown) in advance and carried to the vicinity of the front cap 20 or the auxiliary roller 7, is hooked on the guide bar 9a, the winding position is regulated, and the yarn Y is wound on the auxiliary roller 7. Next, the auxiliary roller 7 is moved from the bobbin B in the direction indicated by the arrow N, and the yarn Y is wound on the auxiliary roller 7.
In the single bobbin system, the full bobbin is doffed and an empty bobbin is set in its place. In the double bobbin system, the turret rotates 180 degrees, the full bobbin is moved to the standby position, and a turret with an empty bobbin set in its place advances. Next,
The auxiliary roller arm 21 swings again relative to these empty bobbins so that the tip of the auxiliary roller 7 is inserted into the front cap 20, and the guide rod 9a is rotated 90 degrees in the opposite direction to the above to rotate the bobbins B, thereby starting winding of the yarn Y onto the empty bobbins.
Then, the auxiliary roller 7 retreats to the standby position again.

C Problems to be solved by the invention Recently, as shown in FIG.
There is a demand for a winding machine of a type that can fix 2, B3, and B4, but if the above-mentioned conventional technology is applied to this type, for example, as shown in the figure, the auxiliary roller thread guide 9 can be fixed. For the bobbin B1 in the first position, it acts as a guide by operating as described above, but for the bobbin B2 in the second position, it comes out of the thread path and is of no use. Therefore, a guide is required for each bobbin, but in reality it is structurally difficult to install this many guides.

The present invention solves these problems and provides a thread guide position adjustment mechanism that allows one auxiliary roller thread guide 9 to operate effectively for the bobbin at any position, as shown in the third figure. The purpose is to

D. Means for solving the problems The structure of the present invention to achieve the above object is as follows. In other words, in a winding machine in which a plurality of winding bobbins are arranged on a circumference and each bobbin winds yarn supplied from a certain direction perpendicular to the bobbin axis, the winding machine is rotatable around the center of the circle. supported by
An arm whose tip extends from there to the position of the winding bobbin on the circumference, an auxiliary roller rotatably provided at the tip of this arm, and an auxiliary roller installed at the tip of the arm to pass the yarn to the auxiliary roller. A thread guide that guides the thread to be wound and a thread guide position adjustment mechanism that adjusts the thread guide to the same angular position with respect to the thread supply direction regardless of where the arm is located on the winding bobbin. .

More specifically, a plurality of take-up bobbins having horizontal rotation axes on the same circumference extend to a position intersecting the center line of the circumference, and a bracket is fixedly supported by the bracket and extends horizontally on the center line. an elongated intermediate shaft, an arm whose base is rotatably supported by the intermediate shaft and whose tip extends on the radius of the circumference up to the circumference, and an arm provided on the bracket and for rotating the arm. a rotating means; an auxiliary roller support tube fixed to the tip of the arm and having an axis parallel to the intermediate shaft; and an auxiliary roller rotatably supported within the support tube and having an axis parallel to the intermediate shaft. a shaft, an auxiliary roller fixed to the tip of the roller shaft, and auxiliary roller rotation means provided on the bracket and connected to the auxiliary roller rotation shaft;
a yarn guide that is close to the outer circumferential surface of the auxiliary roller and is rotatably supported near the tip of the auxiliary roller support tube; and a yarn guide that is fixed to the yarn guide and rotatably supported by the auxiliary roller support tube. A movable vehicle concentric with the auxiliary roller, a fixed vehicle concentrically fixed to the intermediate shaft, and these movable vehicles and the fixed vehicle coupled together to cause the movable vehicle to move in a parallel circular motion about the fixed vehicle or vice versa. and an engaging member adapted to move in a similar manner.

E. Effect When the arm rotates around the intermediate shaft and moves to the bobbin position, the moving wheel revolves around a fixed wheel fixed concentrically to the intermediate shaft. In addition, since the moving vehicle is rotatably supported by the auxiliary roller support cylinder, if the diameters of the moving vehicle and fixed vehicle are the same, they will not rotate but will move in parallel; if their diameters are slightly different, they will rotate slightly. . Therefore, the thread guide attached to the moving vehicle is always at the same or almost the same position with respect to the thread path regardless of the position of the bobbin, and the waist winding around the auxiliary roller is reliably performed.

F. Embodiment The present invention will be described below based on an embodiment shown in the drawings.

In FIGS. 1 to 3, a plurality of winding bobbins B1 and B having horizontal rotation axes on the same circumference are shown.
A bracket 1 extends to a position intersecting the center line of the circumferences of B2, B3, and B4, and a horizontally extending intermediate shaft 2 is fixedly supported on the center line of the bracket. The intermediate shaft supports the base of an arm 3 whose tip extends onto the circumference, and the arm is rotatable about the intermediate shaft by arm rotation means 4. An auxiliary roller support cylinder 5 having an axis parallel to the intermediate shaft 2 is fixed to the tip of the arm 3. The support cylinder is provided with an auxiliary roller shaft 6 which is rotated via an auxiliary roller rotation means 8 and has an axis parallel to the intermediate shaft 2, and an auxiliary roller 7 fixed to the tip of the shaft.

A mobile vehicle 10 is rotatably fitted and supported on the auxiliary roller support tube 5 . The moving wheel is concentric with the auxiliary roller 7, and a thread guide 9 is fixedly supported on the wheel. On the other hand, a fixed wheel 11 concentric with the intermediate shaft 2 is fixed to the bracket 1. The moving vehicle 10 and the stationary vehicle 11 are chain wheels having the same diameter, and a chain 12a as an engaging member 12 is connected to both chain wheels.

Further, the arm rotation means 4 is rotatably supported by a motor 4a fixed to the bracket 1, a reduction gear 4b, a driving pinion 4c provided on the reduction gear side, and the intermediate shaft 2, and , a driven gear 4d fixed to the arm 3, and a brake device 4e that stops the gear when it rotates by a predetermined angle.

Next, the auxiliary roller rotation means 8 includes a motor 8a fixed to the bracket 1, and first to fourth pulleys 8b, 8 for transmitting rotation to the auxiliary roller shaft 6.
c, 8d, 8e, the first belt 8g connected between the first pulley 8b and the second pulley 8c, and the third
The second pulley connected between the pulley 8d and the fourth pulley 8e
It consists of a belt 8f and a tension pulley 8f. The first pulley 8b is attached to the shaft of the motor 8a, and the second
The third pulleys 8c and 8d are fixed to the intermediate shaft 2, and the fourth pulley 8e is fixed to the auxiliary roller shaft 6, respectively.

The moving vehicle 10 has a moving vehicle main body 10a consisting of a chain wheel.
and a boss 10b which fixes the main body and is rotatably fitted onto the auxiliary roller support cylinder 5, and a circumferential air passage 10c is provided on the inner peripheral surface of the boss 10b.
is provided, and the air passage is connected to guide rod swinging means 9b, which will be described later, via an air pipe 14. The auxiliary roller support cylinder 5 is also provided with an air passage 5a that extends along the auxiliary roller shaft 6 and communicates with the air passage 10c.

The thread guide 9 is close to the outer circumferential surface of the auxiliary roller 7 and is fixed to the vehicle body 10a near the tip of the auxiliary roller support cylinder 5. A guide rod 9a extending in the horizontal direction, a guide rod swinging means 9b using an air motor so as to rotate the guide rod forward and backward by 90 degrees in the horizontal plane, and the swinging means are attached. It consists of a guide bracket 9c. The guide bracket is fixed to one side of the vehicle main body 10a via a mounting plate 13.

The bracket 1 is connected to a piston cylinder mechanism (not shown), and the entire adjustment mechanism is movable toward and away from the bobbin B in the axial direction. Therefore, the tip of the auxiliary roller 7 can enter into the front cap 20 of the collect when the bracket 1 approaches.

The operating state will be explained above.

While the bobbin B is in winding operation, the position adjustment mechanism of the present invention is retracted to the opposite side of the bobbin (to the left in FIG. 2) as indicated by arrow N by the operation of a piston cylinder (not shown).
Further, as shown in FIG. 3, the auxiliary roller 7 is held at the lowest value and stands by.

When the bobbin B1 in the first position is now fully wound, the arm rotating means 4 receives a command from a sensor not shown.
is activated. That is, in FIG. 1, the motor 4a
is started, and by rotating the gear 4d in the direction of arrow P via the pinion 4c, the arm 3 is rotated in the direction of arrow Q, and after the auxiliary roller shaft 6 is aligned with the axis of the bobbin B1, the motor is rotated. 8a stopped,
It is stopped at a predetermined position by actuation of the brake 4e. Subsequently, the auxiliary roller rotation means 8 starts operating and rotates the auxiliary roller 7. Further, the piston cylinder mechanism (not shown) operates to move the position adjustment mechanism including the auxiliary roller 7 toward the bobbin indicated by arrow M (right side in FIG. 2), and the auxiliary roller 7 is moved as in the conventional case. One end is inserted into the front cap 20 at the front end of the bobbin B1 in a loosely fitted state.

Next, the compressed air passes through the air passages 5a, 10c and the air pipe 1.
4 to the guide rod swinging means 9b, and the guide rod 9a, which had been oriented parallel to the auxiliary roller shaft 6,
Rotate 90 degrees in the horizontal plane. As a result of this rotation, the yarn Y, which has been previously pushed by the winding yarn guide rod (not shown) and carried to the vicinity of the front cap 20 or the auxiliary roller 7, is moved to the guide rod 9, as in the conventional case.
It is hooked at point a and guided correctly onto the auxiliary roller 7, and as the roller rotates, it is wrapped around the waist. Then, the end of the fully wound yarn is cut by a cutter provided at the tip of the front cap 20, and then the auxiliary roller 7 is pulled out from the front cap, and the arm 3 is moved to the empty bobbin B2 position to be wound next. After operations such as rotation of the bobbin B2, insertion of the auxiliary roller into the front cap to which the bobbin B2 is attached, start of winding around the bobbin B2, and pulling out of the auxiliary roller 7,
The auxiliary roller 7 waits at the standby position. The previous full bobbin B1 is pulled out during the above operation, and a new empty bobbin is installed.

According to the present invention, when the arm 3 rotates around the intermediate shaft and moves to the bobbin position,
Since it is rotatably supported by the auxiliary roller support tube 5, the moving vehicle 10 revolves around a fixed wheel 11 that is fixed concentrically to the intermediate shaft 2. Further, if the diameters of the moving vehicle and the fixed vehicle are the same, the moving vehicle 10 does not rotate but moves in parallel. Therefore, as shown in Figure 3,
The thread guide 9 attached to the moving vehicle 10 is always at the same position with respect to the thread path of the thread Y to be wound regardless of the position of the bobbin B, and the waist winding around the auxiliary roller 7 is reliably performed.

Furthermore, in the case where the mobile vehicle 10 reciprocates, that is, the mobile vehicle 10 moves counterclockwise in FIG. 1 from bobbin B1 to B4, and then clockwise from B4 to B1. There is no problem even if the diameters of the mobile vehicle 10 and the stationary vehicle 11 are slightly different.
In this case, although the mobile vehicle 10 rotates slightly, the yarn guide does not come off from the yarn path.

In the above embodiment, a chain wheel and a chain were used as the engagement member 12 between the moving vehicle 10 and the stationary vehicle 11, but instead of this, a pulley, a belt, a rope, a wire, etc., or an odd number of engagement members 12 were used. A gear transmission system with an intermediate gear may also be used.

Further, the guide rod swinging means 9 in the thread guide 9
Although an air motor is used as b, the present invention is not limited to the above embodiment, and a hydraulic motor or the like may be used as long as it rotates the guide rod 9a by 90 degrees in a horizontal plane.

G. Effect of the invention As described above, the present invention is applied to a winding machine in which a plurality of winding bobbins are arranged on the circumference, and each bobbin winds yarn supplied from a certain direction perpendicular to the bobbin axis. , an arm whose tip extends from the center of the circle to the position of the take-up bobbin on the circumference; an auxiliary roller rotatably provided at the tip of the arm; A thread guide that guides the auxiliary roller for waist winding, and a thread guide position adjustment mechanism that adjusts the thread guide to the same standby position in the thread supply direction regardless of where the arm is located on the winding bobbin. Ta. Therefore, it is possible to use one auxiliary roller yarn guide to start winding any of the bobbins having horizontal rotation axes on the same circumference, and to operate the guide rod for the yarn path at the end of winding. This makes it possible to apply it to yarn winding machines equipped with multiple bobbins.
