Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for drawing out a yarn sheet from a group of warping beams in a sizing process.

(Prior art) As shown in Fig. 4, the warp yarns for fiber forming conventionally used in looms are warp beams (1) (+ ) in the creel part (2) depending on the total number of warp yarns required for 0wA formation (usually 8 to 3
0 pieces) are supported in parallel in the front and back direction, pulled out slightly upward so that each yarn sheet does not come into contact with each other while being pulled out, and each pulled out yarn sheet (3) (3) is set in a predetermined position. They are stacked on rollers (4), transferred to a saw box (7) via intermediate guide small rollers (5), cushion rollers (6), etc., and then passed through a drying process and wound onto a beam. It is formed by

(Problems to be Solved by the Invention) However, as described above, in the conventional sizing process, the thread sheets (3) (3) from the warp beam group are pulled out slightly diagonally upward, and the guide rollers (4) is supported by a bearing fixed at a height position determined by considering the outer diameter of the flange of beam (1), so thread sheet < 3)
When the winding diameter decreases as the yarn sheet (3) is pulled out, the pull-out angle of the yarn sheet (3) (3) changes as shown by the chain line in Figure 1, and the pull-out angle gradually increases. The conventional drawing method in which air resistance increases and therefore each yarn sheet is separated from each other by a considerable distance before reaching the guide roller (4) has the following disadvantages. occurs.

・B) When pulling out the yarn sheet from the new warping beam, the yarn sheet pulled out from the rear warping beam comes into contact with the outer periphery of the flange of the front beam, causing disturbances on both sides of the flange, making it difficult to align the yarn. The only negative effect is that it takes many closings to align the thread sheets of the front beam, and there is a lot of thread loss.

(Note) The distance in the east where the yarn sheet pulled out from the rear beam and the front yarn sheet are close to each other is long, and when the spun yarn is put in, it takes a long time for the spun yarn to be held between the yarn sheets. It becomes loose and it is difficult to insert the spun thread accurately.

c) If a thread breakage occurs in the thread seam 1 of the lower layer, the repair work is complicated.

d) As the winding diameter of the warping beam becomes smaller, the pull-out angle becomes larger, increasing air resistance and causing disturbance in the thread sheet.

(Means for Solving the Problems) The present invention aims to improve the disadvantages of the conventional yarn sheet drawing method described above, and is aimed at improving the disadvantages of the conventional yarn sheet drawing method described above. A guide roller provided at a position where a plurality of drawn yarn sheets are superimposed is supported so as to be movable up and down, and the guide roller is gradually moved in accordance with the decrease in the winding diameter of each warping beam as the nine yarn sheets are pulled out. The yarn sheet from each warping beam is lowered and withdrawn in a substantially horizontal direction at a substantially constant withdrawal angle.

Regarding the means for raising and lowering the guide roller, the support bearings at both ends of the guide roller are attached to a vertically movable column, a rack is provided on the side of the column and a pinion is engaged with the pinion, and the pinion is connected by a winding diameter detector of a warping beam. Appropriate methods include a method in which the guide roller is rotationally driven by a controlled low-speed motor, a method in which the support bearing portion of the guide roller is screwed onto a vertical screw shaft, and the vertical screw shaft is similarly rotated by a low-speed motor, a hydraulic method, etc. There are no particular limitations on the elevating means for the guide roller.

(Function) As the winding diameter of the yarn sheets of the warping beam decreases, the guide rollers at the overlapping position of each yarn sheet are gradually lowered. The thread sheet is always pulled out in a nearly horizontal state.

(Example) In Fig. 0, which will be explained with reference to Figs. 1 and 2 which show examples of the present invention, (1) is a warping beam, and (2) is a large number of warping beams (+) (1). In this embodiment, the cream part (2) is a creel part that is supported in parallel.
The warping beam (1) (+) is supported in two stages, upper and lower, with the upper warping beam (101) and the lower warping beam (
The yarn sheets (3H3) drawn out from the +) (+) are separately overlapped on a guide roller (4H4), one being guided to a first saw box (7) and the other to a second saw box (not shown). Glued. (5) is an intermediate guide roller, (6) is a cushion roller, (8) is a nip roller, and (9) is a draw roller.

The present invention supports the above-mentioned guide roller (4)<4) so as to be movable up and down, and gradually lowers it in response to the decrease in the winding diameter of the warping beam as the yarn sheets (3) and (3) are drawn out. The drawing angle of the yarn sheets (3) (3) from the warping beams (1) (+) is kept constant.

That is, as shown in FIG. 2, struts (12) (12) supported vertically by fixed bearings (II) (II) are provided on both sides of the outlet of the creel (2), and the struts (12)
) (12) at the predetermined height position of the guide roller (4) (4)
Bearings (+3>(+3)) that support both ends of the support column (12)<12) are fixed, and U and Tsuk(
+4) (+4) is provided to engage the binions (+5) (15> with the racks (14) (14), and the binion shaft (

When the yarn layer of the warping beam (1) becomes small, the limit switch (23) of the winding diameter detector (22) detects the warping beam (1). The low speed motor (20) is stopped.

Note that the guide roller (4) that has descended to the lowest position is connected to the shaft (18) above.
can be returned to a predetermined height position by rotating it using a manual handle (not shown).

In addition, when aligning each yarn sheet immediately after replacing the warp beam with a new warp beam, the guide rollers are set so that all the yarn sheets are horizontal and overlap vertically, and the rear yarn sheet is placed on top of the previous yarn sheet. It is desirable to guide the yarn sheets by overlapping them.

After the thread alignment is completed, it is preferable to move the guide rollers slightly upward and run them on each beam to such an extent that the upper and lower thread sheets do not come into contact with each other.

(Effects of the Invention) As described above, in the present invention, a plurality of yarn sheets (3) are pulled out from a plurality of warping beams (+) (+) supported in parallel on a creel part (2). A guide roller (4) provided at a position where yarn sheets (3) are overlapped is supported so as to be movable up and down, and the diameter of the bobbin winding of each warping beam (+) (1) is reduced as the yarn sheet H) (3) is pulled out. The guide roller (4) is gradually lowered according to the thread sheet (2).
) (2).

Each thread sheet can be drawn out while keeping the drawing angle of each thread sheet (3) <3> almost unchanged and in a substantially horizontal direction. In addition, during the initial thread sheet alignment work, the flange of the front beam serves as an ear guide for the thread sheet pulled out from the rear beam, making thread alignment easier, reducing work time, and Not only does it help reduce losses, but it also prevents the edges of the yarn sheet from becoming disturbed during withdrawal. Furthermore, when inserting a time series, the space between the upper and lower thread sheets is small, so the inserted time series is sandwiched between the upper and lower thread sheets in a shorter time than before, improving workability and preventing thread breakage, especially in the lower layer. Even when a thread breakage in a thread sheet is to be corrected, the upper sheet can be repaired separately, which is beneficial for operation.
