Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a winding layer adjusting device in a partial warping machine that uniformly winds warp yarns on a drum to prevent disturbance of the female yarn layer.

BACKGROUND ART Conventionally, when warping yarns are warped using a partial warping machine, disturbances occur in the wound yarn layer due to changes in yarn tension.

Therefore, in order to prevent the above-mentioned winding layer from multiplying, the individual warp threads pulled out by the creel are passed through a brake member such as a brake member or a spring to keep the tension constant. If the parts are clogged with cotton waste, or the warp threads have come off in one piece, or if the cheese diameter is different,
Changes in warp tension can occur due to changes in the diameter of the cheese as the thread is pulled out, differences in the distance between the cheese and the thread path, differences in the front and back of the twilling reed stand and creel, differences in the angle of the threads, and other gluing of the cheese, etc. It is a state in which many elements are mounted.

Furthermore, in a partial warping machine, at most 500 warp yarns are pulled out at a time from the creel, and it is impossible to completely equalize the tension of this large number of yarns. Therefore, in a partial warping machine, the warp threads wound around the drum inevitably have uneven tension, resulting in an uneven winding state in which the part with weaker tension has a larger diameter, and more perfect warping cannot be achieved.

C. Object of the Invention The object of the present invention is to absorb and eliminate the uneven warp tension generated between the creel and the drum at the wound layer portion of the drum.

2. Structure of the Invention The present invention provides a holding plate having approximately the same length as the I separation at the tip of an arm that is vertically swingably housed on a support shaft provided on a flow table, and the holding plate is The winding yarn is placed on the drum at the contact point between the partial winding threads of the winding layer on the drum by being fused and placed in the direction of the drum axis.

E. In the drawings of the embodiment, (1) is a partially warped warp, (
2) is a drum that winds the warp threads while partially warping them, and (3) is a reed that focuses and guides a large number of single threads in parallel so that they have a predetermined partial warp width. Kusenryu gt+
The warp winding section of the partial warper is constructed with these drums (2) and reeds (3) as the main parts.

In the present invention, on the partial yarn layer (:l) of the yarn layer (1a) on the drum (2), the entire width thereof is directed in the direction of the drum axis and comes into contact with the contact point of the winding yarn. A presser plate (5) on which it is placed is provided. The holding plate (5) is made of a metal plate having a smooth surface and elasticity, such as a stainless steel plate, and is curved into an arc shape to have approximately the same length as the radial flow. Moreover, a roll may be used instead of the presser plate having the above structure. In order to place this presser plate (5) on the partial yarn layer (1b), for example, a support part (6
) The arm (8) is provided in a cantilever shape at the base of the arm (8) which is pivotally connected to the support shaft (7) which is rotatably fitted and attached to the support shaft (7). As a result, the arm (8) swings in the vertical direction about the support shaft (7), and as a result, the presser plate (5) moves from time to time to the partially wound yarn layer (1b).
) and is also released above this.

When the pressing plate (5) is placed on the partially wound layer (1b), it makes almost a linear contact across the wound layer metal unevenness and pressurizes the surface of the wound layer with its own weight. In addition, to prevent the presser plate (5) from coming loose from the partial yarn layer (1b), the arm (8) must be swung upward to avoid disturbing the yarn splicing, preparation for starting the 7-leg Vi winding, etc. This frees and straightens the plate (5). In order to position the plate (5) at a distance of 4 - e.g. from the pivot point (8a) on the arm (8) shown and opposite to the arm (8) The balance weight (9) is movably provided, and the presser plate (5) is placed on the partial bobbin J shell (6) with an appropriate pressure depending on its front and back position, and the balance weight is pushed to the appropriate position. Let Nai Waku-san correct it. Incidentally, a spring may be used instead of the no-ransquat to perform such an operation. Also,
In order to pressurize and place this presser plate (5) on all 1.1 items of the partial thread layer (1b), hold the presser plate (S) as shown in the figure.
To install the push-in arm on i6i, use the fit-in end Mi of the support shaft (7).
Insert the female screw (1) into the operating rod (I) and insert the male screw (11) that is screwed into the female screw (lO) into the support part (6).
), fit it into the other end, provide a bolt on the outer end of it, turn the handle (α2) to move the support shaft (7) left and right, and attach it to the presser plate (5). Have them take a given position.

In addition, in g6 minute warping, the winding layer is wound up on the slope, but the pivot 4 of the arm (8) that houses the presser plate (5)
Since the part is connected to the radial flow (3) through the support part (6), the holding plate (5) has a partially wound yarn layered shape.
) to the partially wound layer (1b).
With the above structure, the pressure is always applied reliably over the entire width, and the presser plate (5) is used to partially warp the yarn layer (1b).
)'s @fX thread contact point.

Pressure is applied over the width of the winding layer base in almost line contact, and this pressure causes the winding yarn to be guided in a grip R with an appropriate strength at the contact point.

EFFECTS OF CONSIDERATION In the present invention, the wound yarn layer on the drum is lifted up and collected on the drum while pressurizing the contact area of the wound yarn between the 11th and 11th corners of the drum with a presser plate. Even if there is a portion of the winding thread with low tension, the thread is tensed due to the guidance of the pressurizing plate, and the surface of the winding thread layer is uniformly aligned over the entire width, resulting in a perfect yarn layer with no unevenness. Warping is done. Furthermore, since the warp yarns are firmly lifted by the drum by the presser plate as described above, there is no need to spend time and effort on adjusting the brake using a washer or the like in the creel section.

The back of the wood is an extremely industrial proof that can easily adjust the disorder of the winding layer caused by the warp tension change and create a drum with a well-balanced winding layer. be.
