Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a maul yarn manufacturing apparatus having a stable braided core without bias.

Traditionally, mole yarn is made by cutting a large number of short fibers into appropriate lengths and sandwiching them between a core yarn and a presser yarn and twisting them to fix the short fibers, or by twisting twisted yarns. Those with a large number of fluffs sandwiched between the gaps, and those with a large number of fluffs or loops formed in the twisted yarn.
A wide range of products have been manufactured in general.

Various types of apparatus have been proposed for producing these mole yarns, including an apparatus using a steel belt as disclosed in Japanese Patent Publication No. 46-25538.

However, mole yarns made using these conventional methods or known devices have difficulty retaining fluff and tend to fall off.
It takes a lot of effort to peel and handle it during subsequent knitting and weaving, which lowers the production efficiency of the product, and the wear resistance of the product is poor, resulting in an unavoidable decline in quality.

For this reason, recently, in order to prevent the fluff from falling out of the nip type mall yarn, it has been considered to use the lace making machine that was conventionally used for making braided cords. A new method has been developed in which the fluff is made by floating a part of the threads that make up the braided body using a special method to form a loop, and then cutting the loop.

This new manufacturing method for molle yarn is much improved in terms of ease of handling, since the fluff is made from threads that are integrated with the core, and there is no risk of it falling off. When using a braiding machine (1), the composition of the braid that becomes the core becomes unstable due to tension fluctuations, etc., and this causes potential distortion of the braid core, which may affect the quality of the resulting maul yarn. This leaves the disadvantageous aspect of inviting a decline.

The present invention aims to provide a device for eliminating the defects in new production of molle yarn, forming a stable braid core, and stabilizing the quality of molle yarn. A loop-forming hook is attached to the machine so that a loop is formed by a part of the braid-constituting yarn, and fluff is generated, and the braid-forming part is placed approximately at the center of the loop-forming hook. The device is characterized in that a needle-like guide with a sharp tip is provided upward so that the tip is located close to the needle.

Hereinafter, its specific configuration will be further described in detail with reference to the accompanying drawings.

The figure shows one example of the molle yarn manufacturing apparatus according to the present invention, and in the figure, 1 shows a machine base 2 of a lace-making machine arranged on the machine base 1 with an appropriate distance therebetween. An annular orbit R1t R formed on the plate 3 between the plate 3 and the plate 3
2, which is a drive gear for moving the carrier 4 holding the bobbin 5 along the 1, which is appropriately linked to a motor.
The power is transmitted to each gear in sequence from the two driving gears.

Further, 7 is a loop forming hook provided on the plate to form a loop with the thread using a part of the bobbin 5, two or more hooks are provided, and the upper part is used to maintain the loop interval. It is a guide part 7' that can be
Furthermore, cutters 8 for cutting the loop formed by the loop-forming hook 7 are provided above the cutters 8 so as to face each other with their blade surfaces facing outward.

Further, above the cutter 8, there are provided delivery rolls 9, 9' supported by a bracket 1'' on the stand via a support column 1' erected from the machine stand 1. The cut moldings are sent to the subsequent process.

In the above-mentioned apparatus for producing a braid-like braided yarn, the present invention particularly has a needle-like guide for the core thread indicated by the reference numeral 6 as shown in the figure, disposed approximately at the center of the loop-forming hook 7.

This needle-like guide 6 has its lower end supported approximately at the center of the annular track R1tR2 on the plate surface 3, and its upper end forms a needle-like point and is shown in the figure as being integrated upward into the component part of the braided cord body. Then, the core yarn fed to the guide 6 by appropriate means, that is, the core yarn for pressing the braid, is fed into the composition section while being spliced, thereby stabilizing the shape of the braid and smoothing it into the composition section when forming the braid body. Yarn feeding is performed.

In addition, although one needle-like guide is provided in the figure,
Of course, it is also possible to provide two pieces so that they are combined with each other in the composition part.

Further, in the figure, although not directly related to the present invention, a rotary table 12 on which a can 13 is placed is attached to the side of the machine stand 1 of the string making machine and is rotatably supported by an appropriate support mechanism 11. It can be rotated by the rotation of a rubber roll 20 fixed to the tip of a central penetrating shaft 17 of the bevel gear 18 via a bevel gear 18 driven by a drive gear 2 disposed at the bottom of the plate 3. It has become.

In this case, the center penetrating shaft 17 slides left and right through the support members 15 and 16 attached to the machine base 1 and the support member 19 attached to the bevel gear 18, and moves between the rubber roll 20 and the rotary base 1.
The contact position with 2 can be changed.

In the figure, 14 is a through hole for passing the maul yarn Y into the can 13, and the maul yarn Y pulled up by the delivery rolls 9, 9' passes through the guide roll 10 and enters the can 13 in an almost tension-free state. Let it hang down to Kens 1
The yarn yarn Y is given an untwisting effect by the rotation of the yarn 3, and is then stored in the can 13.

The manufacturing device of the present invention consists of the device as described above, and when making a mole yarn using the binding device, a suitable thread is wound around the bobbin 5 as a raw material, and the annular orbit R1t R2 of the plate 3 is moved. The handle on the carrier 4 attached to the carrier 4 pulls up the thread as appropriate in the same way as a known lace-making machine, and the braided body is sequentially formed by driving the thread, but at this time, some of the bobbins 5 The thread passed through the outside of the loop-forming hook γ and pulled out from the bobbin 5 rises to touch the upper surface of the fufu, and is given a predetermined loop spacing by the upper loop spacing guide 7'.
1\ rises to reveal a state in which a loop is pulled out laterally from the braided body, and this loop is cut by the cutter 8 above it to generate fluff and form a mole yarn Y.

The braid composition by the above-mentioned braid composition mechanism and the production of a mole yarn by loop formation will be described in more detail as follows based on the example shown in FIG.

That is, in the illustrated example, the annular orbits R1t and R2 run along the circumferences of eight circles of the same diameter circumscribed on the plate 3, using half of the circumferences thereof, press the buttons at the contact points of the adjacent circles, and advance in the intersecting directions to form a figure 8. Each orbit R1 or R2 has eight carriers 4, 4a to 4h, 4.
``a~4''h, with an interval of 180° angular range if these carriers are on the same orbital carrier, while on the other orbit carriers 4/a~4'h or 4a~4
h, with an interval of 90° angle range, and both orbits R
During chanting between 0 and R2, the vehicle runs in the opposite direction.

When the carriers cross each other on the orbits by passing with an angular deviation of 90° at the contact points of the containers, the threads drawn from the bobbin of the carrier intersect with each other and composition is performed.

Thus, it died between the carriers running sequentially,
This is also carried out at each contact point, and if there is a core yarn fed out by the core yarn guide 6 in the center of FIG. 3, a braid covering composed of intersecting threads is formed around the core yarn.

However, in the composition of the braid mentioned above, the ring orbit R1 of the present invention
A pair of loop-forming hooks 7 located on both sides of the core yarn guide 6 in tR2 are arranged in a figure-eight shape formed by the pedestal-like trajectory R1tR2 and clicked when the traveling carrier reaches a specific position. , that is, 4a, 4 on trajectory R1 in the figure
When passing through position e and being assembled, the thread pulled out from the bobbin of the carrier engages the loop forming hook 7 and rises, and the upper loop spacing guide section 7' creates a spacing corresponding to the loop length. Hold it in place and pull it upwards.

At this time, the yarn drawn out from the bobbin passing through one of the tracks R2 forms a braid without forming a loop inside the hook 7'.

Therefore, at this position, the yarn passing through the trajectory R1 in the composition forms a loop, and is then cut by a cutter, if any, to lift a part of the yarn constituting the braid to obtain a mole yarn formed into a loop.

Of course, the number of hooks 7 is related to the number of carriers, and it is best to set the number of hooks to within 1/2 of the number of carriers at most in order to form loops and naps that will not fall off.

However, in the above case, the core thread is simultaneously pulled out together with the threads constituting the braid, attaches to the core thread splicing needle guide 6 and rises, and merges with the braided body having a composition that does not form the braid structure at the time of the above-mentioned composition. Since it is attached to the braided body, compositional deviation of the braided body is prevented and elongation is suppressed at the same time.

In the illustrated example, the loop closed end is cut by a cutter 8 to form a yarn that can produce fluff, and then passed through delivery rolls 9 and 9' and a guide roll 10 into a rotating can 13 through its through hole 14. The fibers are filled and housed while undergoing untwisting or untwisting action in a tension-free state.

The method of storing the yarn is not limited to just that, but it is also possible to immediately wind up the yarn while giving it a loose twist.

As described above, it is completely different from conventional mall yarn manufacturing equipment, and utilizes the configuration of a lace-making machine, and in addition, loop-forming hooks are arranged to draw out loops using part of the threads that make up the braid. Therefore, it is possible to efficiently produce a molle yarn, and furthermore, in the production of such a molle yarn, a needle-like guide is arranged so as to be integrated into the composition part, and the core yarn is attached to the guide. Since it is made to merge with the braided body, the core yarn can be attached to the braided body very smoothly and stably, and the stable supply of the core yarn to the composition part can prevent the bias of the braided core body. It has the effect of preventing this and improving the quality of the molle yarn, and together with the simple and efficient production of molle yarn as a molle yarn production device using a new type of stringing machine, it contributes to its practical application. He is a very curious dog.
