Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tension device for a workper creel.

(Prior Art) V-type creels and parallel-type creels are known as creels for warpers, particularly for rough warping machines. A V-shaped creel is a V-shaped cheese hanging frame that supports a large number of cheeses. The direction of the yarn is changed by hanging it on a drop wire for detecting yarn breakage on a unit bar provided correspondingly to the yarn breakage, and then the yarn is sent to the warping machine in front. On the other hand, a parallel creel has a cheese hanging frame and a compensator frame installed in parallel on each side of the center line of the machine. The yarn is tensioned by a tension device installed in the machine, passed through a number of yarn guides placed perpendicular to the center line of the machine, and then directed to the warping machine at the front. It is ready to be sent.

(Problems to be Solved by the Invention) Conventional V-type creels are based on the premise that the yarn is wound onto a rough winding beam at a high speed of 600 to 1000 m/min, and most of the yarn tension during winding is applied to the yarn. Since the tension was applied by air resistance during running and no tension device was installed, the distance to the warper was different between the yarn pulled out from the cheese at the front of the creel and the yarn pulled out from the cheese at the rear. This difference caused a difference in tension. Furthermore, when warping a highly twisted yarn or a composite yarn of a filament yarn and short fiber yarn, the yarn tension was insufficient and it was not possible to wind the yarn to a uniform hardness.

Therefore, when the speed of the loom reaches a high speed of 60 OR/M as it has recently, there is a problem that there is a delay in opening some warp yarns during the weaving process due to the difference in tension between the yarns wound around the beam. there were.

On the other hand, the conventional parallel creel has a compensator frame with a large number of tension washers (500 to 6
00) tension devices were provided, so when readjusting the yarn tension due to a lot change, it was necessary to replace the tension washers one by one with ones of different weights, which was extremely troublesome.

The present invention provides a tension device for a warper creel that can be used with both a V-type creel and a parallel-type creel, and allows tension adjustment to be performed extremely easily.

(Means for Solving the Problem) Fixed columns are erected corresponding to the vertical rows of cheese on the cheese hanger frame, and clamp-type tension devices are attached to the fixed columns corresponding to each cheese in the vertical rows. One of the clamping pieces and the yarn guide are attached, a movable column whose distance from the fixed column can be changed is provided on the side of the fixed column, and the other clamping piece of the pinch type tension device is attached to this movable column.

(Function) By widening the gap between the fixed column and the movable column and separating the clamping piece on the movable column from the clamping piece on the fixed column, a worker standing in front of the fixed column can easily remove the gap between the fixed column and the movable column. Insert your hand toward the cheese hanger frame, pull out the yarn end from the cheese, insert it into the yarn guide on the fixed support, and align this yarn with the surface of the clamping piece on the fixed support. When the strut is moved to narrow the distance between it and the fixed strut, the clamping piece on the movable strut comes into pressure contact with the clamping piece on the fixed strut, and the thread is sandwiched between them.

Then, by finely adjusting the interval between the fixed column and the movable column, the pressure of the clamping piece on the movable column with respect to the clamping piece on the fixed column changes, and the thread tension is adjusted.

(Example) In FIG. 1, l is a cheese support column on which a large number of cheeses 2 are mounted vertically, and a large number of cheese support posts 1 are erected at equal intervals in the direction of arrow A. A molded creel cheese hanging frame is formed. A fixed support 3 (see FIG. 2) is erected in front of the cheese support 1 in correspondence with the longitudinal rows of cheeses 2, and a first yarn guide 4 is provided on the fixed support 3 in correspondence with the cheese 2. , one clamping piece 6a of the clamping tension device 5, the second yarn guide 7, and the drop wire 8 are attached in this order from the cheese 2 side. Note that the first yarn guide 4 and the second yarn guide 7 are integrally formed by bending one wire into a U shape, and one of the clamping pieces 6a is rotatably attached to the fixed support 3 by a bolt 6b and a nut 6C. (see FIG. 2), and the drop wire 8 is attached to a support base 8a fixed to the outer surface of the fixed column 3 so as to be rotatable in the direction of arrow B.

A movable strut 9 is provided on the side (right side in the figure) of the fixed strut 3, and the movable strut 9 has a bolt 6e on the other clamping piece 6d corresponding to one clamping piece 6a on the fixed strut 3. ,
This clamping piece 6d is attached rotatably by a nut 6f and slidably in the direction of the bolt 6e, and is biased by a compression coil spring 6g compressed between it and the movable support 9, and these clamping pieces 6a , 6d form a pinch-type tension device 5 that elastically pinches the yarn Y pulled out from the cheese 2.

The upper end of the movable column 9 is swingably connected to an upper horizontal bar 10 that is slidable in the left-right direction (in the direction of arrow C), and the lower end is connected to the rear part of a lower horizontal bar 11 that is also slidable in the left-right direction. It is removably fitted into a groove 11b formed in the protrusion 11a, and when the lower part of the movable column 9 is pushed backward (in the direction of the cheese 2) and removed from the groove Llb, the movable column 9 can be swung left and right. .

Thus, one end of the upper horizontal bar 10 and one end of the lower horizontal bar 11 have threaded portions 10a and l, respectively.
lc is provided, and the threaded part 10 of the upper horizontal bar 10
The female threaded portion inside the boss portion of the upper sprocket 12 is fitted into the upper sprocket 12, and the female threaded portion inside the boss portion of the lower sprocket 13 is fitted into the threaded portion 11c of the lower horizontal bar 11, respectively. A first drive sprocket 15 is fixed to a handle shaft 14 supported in the middle of the handle shaft 11, and an endless upper chain 16 is attached to the upper sprocket 12.
However, an endless lower chain 18 is wound around the second drive sprocket 17 and the lower sprocket 13 which are fixed together with the first drive sprocket 15 to the handle shaft 14, and the handle shaft 14 is rotated by hand.
By turning at a, the upper sprocket 12 and the lower sprocket 13 rotate in the same direction and at the same angle, and the upper horizontal bar 10 and the lower horizontal bar 11 move in the same direction and by the same distance.

In the above structure, the movable column 9 is pushed backward (in the direction of the arrow in FIG. 2) and the lower end of the movable column 9 is moved to the lower horizontal bar 11.
from the groove 11b, and further to the right (direction of arrow E in Figure 2).
The end of the yarn Y is pulled out from the cheese 2 and passed through the first yarn guide 4 and the second yarn guide 7 in order, and then hung on the dropper 8 to extend the distance between the fixed support 3 and the movable support 9. When the yarn Y is bent at an almost right angle and guided to the warping machine, the yarn Y touches one of the clamping pieces 6a between the first yarn guide 4 and the second yarn guide 7.Then, the movable support 9 is returned to its original position. , when its lower end is fitted into the groove 11b of the lower horizontal bar 11, the movable column 9 is fixed and the distance between it and the fixed column 3 is narrowed, and the other clamping piece 6d on the movable column 9 is attached to the fixed column 3. The thread Y is held in contact with the upper holding piece 6a. Then, when the handle 14a is rotated, the upper and lower horizontal bars 10.11 move back and forth to the left and right, and these horizontal bars 1
The spacing between the multiple movable columns 9, which are installed at predetermined intervals between 0.11 and the corresponding fixed columns 3, has been finely adjusted, resulting in a large number of clamp-type tension groups! The clamping forces of 5 are adjusted all at once. In addition, when a thread breakage occurs, only the movable support 9 corresponding to the thread breakage 2 is moved laterally to take care of the thread breakage. In this embodiment, the movable support 9 is moved vertically The rotation of the handle 14a is carried out by simultaneously sliding by the horizontal bar 10.11 and by individual swinging using the upper end of the movable column 9 as a fulcrum.
Since the linear movement of a and llc is replaced by a reduction, both tension adjustment and threading work can be easily performed.

In the above embodiment, the cheese strut 1 is guided so that its many upper and lower ends are connected by an endless chain, half of which face the fixed strut 3 side, and the rest face the opposite side, while the thread Y Make a withdrawal.

The other side may be used to change the cheese, and after one drawer is finished, the endless chain may be rotated to change the position.Also, the above embodiment is an example of a V-shaped creel, but the cheese support It is also possible to use a parallel type creel in which a cheese hanging frame consisting of the cheese hanging frame 1 is arranged in parallel. In this case, the dropper 8 is omitted, and the horizontal arm is mounted on the pillars at predetermined intervals in the direction of the bobbin axis of the cheese 2 and in multiple stages. A large number of yarn guides are fixed to the horizontal arm.

In addition, the above embodiment is a scissor type tension type! Of the two clamping pieces 6a and 6d that make up 5, the clamping piece 6d on the movable support 9 is biased by a spring 6g, but the clamping piece 6a on the fixed support 3 may be biased on the contrary. In addition, the shape of the clamping pieces 6a and 6d is not limited to the plate-shaped washer shown in FIG. For example, two parallel wires may be attached to the fixed column 3 in the vertical direction, and the movable column 9 may be provided with one wire that enters between the two parallel wires.

(Effects of the Invention) This invention provides a method of attaching one of the two clamping pieces constituting the clamp-type tension device to a fixed column and the other to a movable column, and by moving the movable column, the distance between the fixed column and the movable column is increased. In other words, since the clamping force of the clamping tension device is changed, the clamping force of a large number of clamping tension devices can be adjusted all at once by finely adjusting the above-mentioned interval, and the movable support mentioned above can be adjusted simultaneously. By increasing the amount of movement of the creel, it is possible to insert a hand between the fixed column and the movable column to thread the thread, and the creel can be used for both the ■ type creel and the parallel type creel. When used in a V-shaped creel, the yarn tension can be increased compared to the conventional one, eliminating tension unevenness even when winding highly twisted yarns or composite yarns, and preventing opening delays during weaving.
