Abstract

[PROBLEMS] With a conventional tufted carpet repair machine, the stitches for planting pile yarn become uneven or meandering, so that even a new worker can easily and stably repair without meandering. The task is to devise a repair machine.

In a repair machine for tufted carpets, stable repair work is provided by providing protrusions on the pressing surface of a pipe needle pressing metal fitting symmetrically around the pipe needle hole and in accordance with tuft gauge intervals. Will be able to.

Description

  The present invention relates to a tufted carpet repairing machine used when correcting a portion where a defect such as yarn breakage occurs during weaving of a tufted carpet.

  Conventionally, defects such as yarn breakage occurred during weaving of tufted carpet, and repair work was carried out by implanting pile yarn in a portion where the pile was not planted with a repair machine.

  Two types of tufted carpet repair machines are generally used. One is a pressing bracket 1 that has a semicircular pressing surface and a smooth curved surface, as shown in FIG. Since there is a through-hole 5 through which the needle 2 reciprocates and the tip of the pipe needle is cut obliquely, the repairing machine suspended by a balancer (not shown) rises with every piercing of the pipe needle 2. The defective portion is corrected while the pile yarn 4 is planted. (The balancer is a device that makes it possible to lightly move the suspended object up and down by hand. Usually, a tufted carpet repair machine is hung on the balancer and used.)

  In another type, as shown in FIG. 3, feed rollers 6 are attached to both sides of the pressing metal fitting 1, and the feed roller 6 rotates positively and reliably pile yarn 4 for each piercing of the pipe needle 2. As it is planted, it rises and the defective part is corrected. In both types, the operator balances the force of the balancer and the weight of the repair machine while holding the pressing bracket 1 firmly against the repaired part where the pile yarn is not planted so that the fabric does not flutter. Then, pile yarn 4 is planted from the bottom to the top for repair.

  However, in both of the above two types, a person with a repair machine balances the balancer's ascending force and the weight of the repair machine, and the pile thread 4 is planted while pressing the pressing bracket 1 against the repaired part, so a slight force is required. When the balance is lost, the stitches for planting the pile yarn may become uneven or meander, and even veteran workers may not always be able to repair reliably.

Patent Document 1 describes an air-hooked gun that can supply a stable thread, but it cannot be easily and reliably repaired.

  An object of the present invention is to devise a repairing machine that allows a new worker to easily and reliably repair a tufted carpet repairing machine as in the past.

  In order to achieve the above object, the present invention provides the following means.

  [1] A tufted carpet repair machine characterized in that protrusions are provided on the pressing surface of the pressing fitting of the pipe needle symmetrically about the pipe needle hole and in accordance with the interval of the tuft gauge. Carpet repair machine.

  [2] The tufted carpet repairing machine according to claim 1, wherein the length of the protruding portion is 10 to 40 mm and the height is 1.0 to 2.0 mm.

  According to the device of [1], in the tufted carpet repair machine, the protrusions are provided symmetrically on the pressing surface of the pipe needle pressing fitting in accordance with the spacing of the tuft gauge. This prevents the repair machine from shifting to the left and right, so that stability is secured, and it becomes easier to plant pile yarn straight and reliable repair can be achieved. (The stitch thread is the thread on the back side of the carpet.)

  According to the device of [2], since the vertical length of the protrusion is 10 to 40 mm and the height is 1.0 to 2.0 mm, the protrusion is a groove between the stitch yarns on the back surface of the carpet. It is easy to plant pile yarn straight, and it can be repaired beautifully and reliably without fluttering of fabric, because the repair machine does not shift from side to side. become.

  The present invention is, for example, a pressing metal fitting 1 as specifically shown in FIG. 1, and a protruding portion 3 is provided on the pressing surface symmetrically about the through hole 5 of the pipe needle 2 so as to match the tuft gauge. .

  The shape of the protrusion 3 is not particularly limited, but may be composed of one protrusion or a plurality of protrusions. The length of the protrusion is preferably 10 to 40 mm. If it is less than 10 mm, it will not be a stable way to hold the repair machine. On the other hand, if it exceeds 40 mm, it is difficult to easily enter the groove between the stitch yarns on the back surface of the carpet, which makes it difficult to work. A more preferable length of the protrusion 3 is 15 to 30 mm.

  Moreover, it is preferable that the height of the projection part 3 is 1.0-2.0 mm. If it is less than 1.0 mm, even if it enters the groove between the stitch threads on the back of the carpet, it will be easy to get over the groove and will not be a stable way to hold the repair machine. On the other hand, if it exceeds 2.0 mm, the fabric will flutter and the stitch yarn on the repaired part on the back side of the carpet will float, and it will not be a clean repair. Moreover, the shape of the front-end | tip of the projection part 3 has a preferable round shape to the extent that it does not stab and catch on a base fabric.

  Furthermore, it is important that the pressing metal fitting 1 of the present invention is provided with the protrusions 3 symmetrically in accordance with the tuft gauge. If the interval between the protrusions 3 does not match the tuft gauge, the pile yarn cannot be planted in the middle of the repaired portion, so that the repair is not clean. Also, if the protrusions are not provided symmetrically, the repair machine will not be stably pressed and will tend to meander left and right. Further, the protrusions 3 are more stable on the repairing machine when they are at both ends of the pressing metal 1.

  As long as the pressing metal 1 is made of metal, there is no particular problem and the pressing metal 1 may be polished so that fibers and the like are not caught on the surface.

<Example 1>
FIG. 1 is a schematic perspective view of Embodiment 1 of the device of the present invention. The pressing surface of the brass pressing metal was shaved with a milling machine to produce a protrusion. The protrusions are parallel with a height of 2 mm, a width of 1.5 mm, a length of 20 mm, and an interval of 17.8 mm (for 7 gauges). Further, the corner of the tip is polished so as not to be caught by the base fabric. When this was applied to a repair machine and repaired, it was possible to perform stable repairs without meandering and without stitch spots.

<Comparative Example 1>
FIG. 2 is a pressing metal fitting 1 of a commonly used type, and is a schematic perspective view of Comparative Example 1. The pressing surface of the pressing metal 1 has no protrusion. When this was attached to a repair machine and repaired, it was easy to meander, so the operator had to put extra power to prevent meandering, which resulted in stitch spots and beautiful repairs. .

<Comparative example 2>
FIG. 3 shows another commonly used type of repair machine. The pressing metal part 1 is the same as that of Comparative Example 1, but feed rollers 6 are attached to both sides of the pressing metal 1 so that the feed The roller 6 rotates positively and assists the movement of the repairing machine ascending while planting the pile yarn 4 from below. Although it is easier to repair than Comparative Example 1 and the effect of the feed roller 6 is felt, it is easy to shake to the left and right, and the stability is not as good as Example 1. Further, in repairing a carpet with nylon filament as a pile yarn, the filament is easily entangled with the feed roller 6, and the surrounding pile may be pulled out.

  By simply changing the pressing metal fitting 1 of the conventional type repair machine to the type of the present invention, stable repair work can be easily performed at low cost.

It is a schematic perspective view of the pressing metal fitting of this invention. Example 1 It is a schematic perspective view of the pressing metal fitting part of the repair machine used frequently. (Comparative Example 1) It is a schematic perspective view of another commonly used repair machine. (Comparative Example 2)
