Description

The present invention relates to a warpark reel tension device.

[Conventional technology]

V-shaped creels and parallel creels are known as creels for warpers, particularly warping machines. The V-shaped creel is a V-shaped standing frame for supporting a large number of cheeses on the left and right of the center line of the machine base. The threads drawn from each cheese are the longitudinal rows of cheese. The yarn breakage detecting drop wire on the unit bar provided corresponding to the above is used to change the direction, and then the yarn is sent to the warper in front. On the other hand, in the parallel type creel, a cheese hanging frame and a compensator frame are erected parallel to each other on the left and right of the machine center line, and the yarn drawn from each cheese corresponds to each cheese and the compensator frame. After tension is applied by a tensioning device provided in the machine and the direction is changed by passing through a number of yarn guides arranged at right angles to the machine center line, the warping in front is performed. It will be sent to the machine.

(Problems to be Solved by the Invention) In the conventional V-type creel, most of the yarn tension during winding is assumed on the assumption that the yarn is wound on the rough winding beam at a high yarn speed of 600 to 1000 m / min. It is given by air resistance during traveling, and since it is not equipped with a tension device, the distance to the warper is between the yarn drawn from the cheese in the front of the creel and the yarn drawn from the cheese in the rear. The difference caused the difference in tension. Further, when warping a strongly twisted yarn or a composite yarn of filament yarn and short fiber yarn, the yarn tension was insufficient, and it was impossible to wind the yarn to a uniform hardness. Therefore, when the speed of the loom reaches a high speed of 600R / M as in recent years, some warp threads are delayed in the weaving process due to the difference in tension between the yarns wound around the beam. There was a problem.

On the other hand, the conventional parallel type creel has a compensator frame with a large number (500 to 600) consisting of a pair of upper and lower tension washers corresponding to each cheese on the cheese rack.
However, when adjusting the yarn tension by changing the lot, it is necessary to replace the tension washers with different weights one by one, which is very troublesome. It was

The present invention provides a tension device for a war park reel which can be used for both a V-type creel and a parallel type creel and whose tension can be adjusted very easily.

(Means for Solving Problems) Fixed struts are erected corresponding to the vertical rows of cheese on the cheese rack, and a sandwich type tension device corresponding to each cheese in the vertical rows is provided on the fixed struts. One clamping piece and the yarn guide are attached, and a movable strut which can change the distance from the fixed strut is provided on the side of the fixed strut, and the other clamping piece of the clamp type tension device is attached to this movable strut.

(Function) By expanding the distance between the fixed strut and the movable strut and separating the sandwiched piece on the movable strut from the sandwiched piece on the fixed strut, the employee standing in front of the fixed strut can move between the fixed strut and the movable strut. It is possible to insert a hand toward the cheese hanging frame, pull out the thread end from the cheese, and insert the thread end into the yarn guide on the fixed support, and then put the thread on the surface of the sandwiching piece on the fixed support. Next, when the movable column is moved to narrow the space between the movable column and the fixed column, the sandwiching piece on the movable column is pressed against the sandwiching piece on the fixed column, and the above yarn is sandwiched between the two. Then, by finely adjusting the distance between the fixed column and the movable column, the pressure contact force of the sandwiching piece on the movable column with respect to the sandwiching piece on the fixed column is changed, and the yarn tension is adjusted.

(Embodiment) In FIG. 1, reference numeral 1 denotes a cheese strut in which a large number of cheeses 2 are arranged in a vertical direction and attached, and a plurality of the cheese struts 1 are erected at equal intervals in the direction of arrow A to form V. A cheese hanging frame of a model creel is formed. Fixed struts 3 (see FIG. 2) are erected in front of the cheese struts 1 in correspondence with the vertical rows of cheeses 2.
Corresponding to the above cheese 2, the first yarn guide 4, one holding piece 6a of the sandwich type tension device 5, the second yarn guide 7, and the drop wire 8 are attached in order from the above cheese 2 side. The first yarn guide 4 and the second yarn guide 7 are integrally formed by bending one wire into a U-shape, and one holding piece 6a has a bolt 6b and a nut.
It is rotatably fixed to the fixed column 3 by 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 side (right side in the figure) moving column 9 of the fixed column 3 is provided, and on the moving column 9, the other clamping piece 6d corresponding to the one clamping piece 6a on the fixed column 3 is bolt 6e. Nuts
It is rotatably mounted by 6f and slidable in the direction of the bolt 6e, and this holding piece 6d is urged by a compression coil spring 6g that is compressed between the holding piece 6d and the moving support 9, A pinch-type tension device 5 for elastically pinching the yarn Y drawn from the cheese 2 by the pinching pieces 6a and 6d is formed.

The upper end of the moving column 9 is in the left-right direction (arrow C direction).
Is slidably connected to a slidable upper horizontal bar 10, and the lower end is detachably fitted into a groove 11b formed in a rear protrusion 11a of a lower horizontal bar 11 which is also slidable in the left-right direction and is moved. Push the lower part of the pillar 9 backward (toward the cheese 2) to form the groove 11b.
When it is removed from, the movable support column 9 can be swung to the left and right. Therefore, at one end of the upper horizontal bar 10 and one end of the lower horizontal bar 11 described above, screw portions 10a and 1
1c is provided, and the female portion inside the boss portion of the upper sprocket 12 is attached to the screw portion 10a of the upper horizontal bar 10, and the female portion inside the boss portion of the lower sprocket 13 is attached to the screw portion 11c of the lower horizontal bar 11. The first drive sprocket 15 and the above-mentioned upper sprocket, which are respectively fitted with the screw parts and are fixed to the handle shaft 14 supported in the middle of the upper and lower horizontal bars 10 and 11.
12 has an endless upper chain 16 and also the above handle shaft 14
The 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, and the handle shaft 14 is manually turned by turning the handle 14a, so that the upper sprocket 12 and the lower sprocket are rotated. The sprocket 13 rotates in the same direction at the same angle, and the upper horizontal bar 10 and the lower horizontal bar move in the same direction by the same distance.

In the above structure, the moving column 9 is pushed rearward (in the direction of arrow D in FIG. 2) to move the lower end of the moving column 9 to the lower horizontal bar 11
Of the cheese 2 by pushing it to the right (in the direction of arrow E in FIG. 2) to widen the gap between the fixed support column 3 and the movable support column 9.
When the end of the yarn Y is pulled out from the first yarn guide 4 and passed through the first yarn guard 4 and the second yarn guide 7 in order, it is further hung on the dropper 8 to bend the yarn Y at a substantially right angle and guide it to the warper. , The first yarn guide 4 and the second yarn guide 7 are in contact with one of the sandwiching pieces 6a. Next, when the movable column 9 is returned to its original position and 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 the movable column 9 and the fixed column 3 is narrowed. The other clamping piece 6d comes into contact with the one clamping piece 6a on the fixed column 3 to clamp the yarn Y. Then, when the handle 14a is rotated, the upper and lower horizontal bars 10, 11
Moves to the left and right, and the spacing between the multiple movable columns 9 mounted between the horizontal bars 10 and 11 at a predetermined interval and the corresponding fixed columns 3 is finely adjusted, and a large number of sandwich type The clamping force of the tension device 5 is adjusted all at once. In addition,
When the yarn breakage occurs, only the moving support column 9 corresponding to the cheese 2 corresponding to the yarn breakage is moved to the side to perform the yarn breakage treatment. In this embodiment, the movement of the moving column 9 is controlled by the horizontal bar above and below.
Simultaneous sliding by 10 and 11 and individual swinging with the upper end of the moving column 9 as a fulcrum are performed, and in simultaneous sliding, rotation of the handle 14a is changed to linear movement of the screw portions 10a and 11c to reduce the size. Thus, both tension adjustment and thread hooking work can be easily performed.

In the above embodiment, the cheese strut 1 has its upper and lower ends connected by endless chains, half of which is directed toward the fixed strut 3 and the other is directed toward the opposite side, while the yarn Y Withdraw. It is also possible to change the cheese on the other side and rotate the endless chain to exchange the positions after the drawer on one side is completed. Further, although the above-mentioned embodiment is an example of the V-shaped creel, it may be a parallel-type creel in which the cheese racks made up of the cheese columns 1 are arranged in parallel. In this case, the dropper 8 is omitted, and horizontal arms are projected on the columns at predetermined intervals in the axial direction of the bobbin of the cheese 2 and in multiple stages, and a large number of yarn guides are fixed to this horizontal arm. Further, in the above-mentioned embodiment, the two sandwiching pieces 6a and 6d constituting the sandwich type tension device 5 are provided.
In the middle, the clamping piece 6d on the movable support column 9 is biased by the spring 6g, but conversely, the clamping piece 6a on the fixed support column 3 may be biased, or both may be biased. Further, the shape of the sandwiching pieces 6a, 6d is not limited to the dish-shaped washer shown in the drawing, but may be formed in the shape of a plurality of wires or bars for bending the yarn Y in a zigzag shape. The parallel wires may be attached in the vertical direction, and the moving column 9 may be provided with a single wire that enters between the two parallel wires.

(Effects of the Invention) According to the present invention, one of two sandwiching pieces constituting a sandwich type tension device is attached to a fixed column and the other is attached to a movable column, and the distance between the fixed column and the movable column is increased by moving the movable column. That is, since the pinching force of the pinch-type tension device is changed, the pinching force of a large number of pinch-type tension devices can be adjusted all at once by finely adjusting the spacing, and the moving column By increasing the amount of movement, the hand can be inserted between the fixed strut and the movable strut to carry out the thread hooking process, and it can be used for both the V-shaped creel and the parallel creel. When used in a V-shaped creel, the yarn tension can be increased more than in the past, uneven tension can be eliminated even when winding a strongly twisted yarn or a composite yarn, and opening delay during weaving can be prevented.
