Description

[Detailed description of the invention] The present invention is a binding yarn osteotomy treatment for torsion lace knitted fabrics in order to efficiently remove binding yarns from knitted tubular knitted fabrics containing binding yarns manufactured by a torsion lace knitting machine. This relates to a knitting machine. Conventionally, torsion lace knitting machines are used to braid silk fabrics, in which knitting yarn is collected toward the center from thread-winding bobbins arranged vertically on spindles driven by spindle plates arranged in a circular shape. Twisted lace is constructed by crossing two adjacent threads.

This torsion lace knitted fabric is knitted in a cylindrical shape, so in order to obtain a plain knitted fabric, unconnected parts are provided in the warp direction at one or two places in the cylindrical knitted fabric, and these are knitted on the left and right sides using binding yarns. The fabric was connected and braided alternately, and after the braiding, the binding threads were separated from the knitted fabric part, developed, and processed into products.This work of separating the binding threads was done by hand each time, and the binding threads were cut and cut. Although the binding yarns were partially pulled out, the silk fabric was vertically long, and due to the structure of the knitted fabric, when the binding yarns were pulled out, the binding yarns that made up the knitted fabric would get tangled and become slippery, making it difficult to work efficiently. There were many inconveniences, such as a decrease in the strength of the knitted fabric and also causing defects such as fraying and twisting of the knitted fabric.

The present inventor has solved the inconveniences caused by the above-mentioned causes, and has developed a binding yarn cutting machine that can quickly and reliably separate the binding yarn incorporated into the torsion lace knitting structure from the silk fabric and dispose of this yarn waste. It is.

Next, the present invention will be explained in detail based on the drawings of the embodiment. Fig. 1 is a perspective view of the embodiment device, in which 1 is a knitted fabric guide section, 2 is a cutting section, 3 is a suction section, and 4 is a suction section. In the winding portion, 5 is the knitted fabric in a state where it has been knitted down, and 5' is the knitted fabric after treatment.

The main parts are shown in FIG. 2 below. 25 is a knitted fabric guide plate, 26 is a winding gear, 27 is an arch-shaped knitted fabric position adjustment member that is removable, and 28 is a knitted fabric. The knitted fabric pressing member 29 is made of a thick steel wire formed of a guide plate having an oval shape and penetrating the side surface and continuously forming straight and curved portions from side to side, and 30 is a knitted fabric pressing member 29. The knitted fabric expanding member is located at the upper part and is made of elastic fine steel wire. It is fitted and attached to the covering member 33.

On the other hand, the knitted fabric expanding member 30 is fitted and supported in one groove in a catch seat 34 having a comb-shaped notch part attached in parallel to the upper part of the main body, and 35 is a lid for covering the cut part 2. A plurality of dovetail holes 36 are bored, a cutout part 37 is provided in the center, and 38 is a hose connected to the suction part 3.

FIG. 3 is a cross-sectional view showing the cut portion 2 on a larger scale. Numeral 39 is a tooth ring, which is fitted onto a shaft 40 and rotates in the direction of the arrow. On the other hand, there is a shaft 41 in a direction perpendicular to the shaft 40, which is indicated by the arrow. A rotary blade 42 that rotates in the direction of the blade and has six radially protruding blades is screwed to the tip, and a fixed blade plate 43 with one end protruding and bifurcated at the bottom is loosely fitted onto the shaft 41. 43a is a fixed blade provided on one side of the bifurcated blade.

44 is the instance piece, 45 is the bearing, 4
6 is a bushing, 47 is a thread waste box surrounding the cut portion, 48 is a suction pipe connected to the hose 38, and 49 is an insertion hole with a leg line.

Next, the usage state of the osteotomy processing machine according to the embodiment of the present invention will be explained with reference to a plan view and a perspective view of the cut portion 2 showing the cutting state shown in FIGS. For this purpose, the lid 35 is removed, and the operating state of related parts is schematically shown.

In the square knitted fabric 5, the binding yarn 50 portion is attached to the knitted fabric guide plate material 28 in advance.
The binding thread 50 is fitted in such a manner that it abuts the lower edge of the binding thread 50, and then folded in two by the silk pressing member 29 with the connecting portion of the binding thread 50 facing downward.

At this time, the binding thread 50 is pulled in a direction perpendicular to the traveling direction of the silk fabric, and both ends of the silk fabric 5 are separated.

Next, as the knitted fabric 5 moves to the outwardly bent curved portion of the knitted fabric expanding member 30, the knitted fabric 5 is further expanded left and right,
Both ends of the knitted fabric 5 are gradually pulled apart, and when the binding thread 50 passed between both ends reaches the tip of the toothed ring 39, it is caught between the fixed blade plates 43 held down by the toothed ring 39 and held down. 50 is positioned, the rotary blade 42 cooperates with the fixed blade 43a to cut the binding thread 50,
It pinches and cuts the binding threads 50 that are sent one after another, and the bone-cut thread waste passes from the thread waste box 47 to the suction pipe 48 and hose 38 to the suction section 3. is inhaled and accumulated in a dust bag (not shown) on the inner thigh.

In the case of the device of the above embodiment, there is only one joining part, but if there are two joining parts facing each other, it is sufficient to provide an upper knitted fabric presser to cut the upper and lower binding yarns at the same time (not shown). ), if several types of knitted fabric guide parts are prepared for different widths of silk fabrics, the osteotomy process of the binding yarn can be performed according to the width of the knitted fabric.

Therefore, according to the present invention, in the work of separating the binding yarns of knitted torsion lace fabrics, the binding yarns can be continuously pressed down and cut into pieces, so that the work of separating the binding yarns can be carried out efficiently, and the winding speed of silk fabric can be increased. By selecting the bone so that the osteotomy condition matches the quality, thickness, etc. of the binding thread, the osteotomy process can be carried out without causing defects in the knitted fabric such as twists and kinks.
