Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pile paraboloid, particularly a tufted carpet repair and pattern forming apparatus.

In the production of tufted carpet, two people use a foot machine with a large number of reciprocating needles arranged in parallel to insert the needles from the back side of the base fabric, and set the VC on the front side of the base fabric. /L/ Lock each yarn with the forming looper, and in that state pull up the knee 1' /L/ to form a protruding pile on the surface of the base fabric. Repeat f'L/ continuously. By doing so, a forest of looped or cut pile piles forms a footed carpet.

And the pile has a screw n that the pile thread itself has,
Due to the operation of the looper, the center line of the thread hole of the needle is installed slightly sideways to the sewing direction.
A pile π false twist structure is generated. This false twisting naturally occurs due to the structure of the tuft machine, and is also one of the features of Cuttela 12 carpet.

During manufacturing using the above-mentioned tufting machine, the pile threads sometimes break, and in one such case, one thread of the pile is missing in the sewing direction. Therefore, a repair process is usually provided next to the manufacturing process using the tufting machine, and repair is performed by forming piles on the chipped portions of the pile.

Therefore, using a conventional repair device, the thread is sent with air to a pipe-shaped needle through which the pile thread can pass, and the waste cloth π2-FJL/ in the repaired area is removed in the morning and the front side of the base fabric is sprayed with air. Some types replenish the pile by repeatedly protruding a pipe and then pulling out a needle. -1: As a similar repair device, a thin protruding rod called a bellow is fully inserted into a pipe-shaped needle together with a pipe thread, the needle is penetrated into the base fabric of the repaired area r, and the pile is protruded by the π bellow on the surface of the base fabric. There are some types that replenish the pile by repeatedly pulling out the needle and then retracting the spatula a little later.

Shi, Shi, Ko-I'7. In conventional apparatuses, the needle is shaped like a pipe through which the pipe thread can pass or the bellows can be extracted together with the pile thread, so the outer diameter of the needle is thicker. Therefore, a large hole was formed in the shape of the base (fjπ○), and the base fabric was destroyed.

This also makes it easier to remove pile threads from the holes during repair work.
There was a risk that the pile would be uneven.

In addition, with tufted carpets, the pile is reduced by σ] as described in 1q, but since the pile is simply planted with the conventional supplementary box device, 1q does not occur.
The repaired area becomes a tissue that is intertwined with other parts, and it is obvious that it has been repaired, which increases the product price.However, conventional repair equipment - passing pile thread through the base fabric and air-! Simply forming a protruding pile on the base fabric member 1i11J with a spatula or a spatula does not require tightening of the pile threads when forming the pile. As a result, the pile threads tend to loosen during work, resulting in poor bonding with the base fabric, resulting in uneven piles.Not only when filling, but also when manufacturing patterned tufted carpet using this device, the pattern is i,! In some cases, the resulting pile became loose and uneven.

The present invention relates to a shade/pattern forming device for pile rugs, and is an object of the present invention to solve the above-mentioned problems of the conventional ones. That is, the purpose is (1) It is possible to correct the shape of the pile, especially the tufted carpet, which has false twist, and there will be no large holes in the base fabric at 16 o'clock. Another object of the present invention is to provide a pile rug repair/pattern forming device in which the pile yarns are sufficiently thickened and the pile yarns do not loosen or become loose.

Similar to the tuft machine, it produces a π pile yarn': 14k, which creates a smooth texture, or false twist structure, and allows for the same original form complementation as in the Noh part. In addition, in the above example, the needle (7) is the thread,
A crab whose center line (x) of (12) is slightly inclined with respect to the sewing direction (V) If the π convergence is n, I, a large pile of 4 will form.

Also, if the center line (X) coincides with the sawing direction (y), it will fit N-1. For example, false twisted yarn) can also form endless piles.

And in the above case (8, pile thread lining mechanism t'!: 31

) retreats by one and a half. Therefore, pile yarn +22
) [As shown in Fig. 4 (b), the tip of the spatula (8) is held on the front side of the base fabric (a) while the thread (22) is held on the back side of the base fabric (a). The identification side ring is closer to the rear [34]
When the movable side ring (24) retreats in the state where the VC is locked, it is pulled backward and forced to give up. ), it is clear that the slack of the pile yarn (22) that was held at the tongue (8)≦n disappears, and the pile yarn (22) on the back side of the base fabric (2) is removed.
) I7] No more sagging. After that, when the bellows (8) is moved back, the loops are formed in the state shown in FIG.

In addition, the yarn sending mechanism (in the field, when the eye of the needle (7) is in 11 advance, the pinion (1
As 9) rotates, the spring f+8) moves forward against Vc,
It meshes with the lower moving thread feed gear (20). This guitar "i'
j20], the upper thread feed gear (21) also rotates, so both gears (20)! The pile yarn (221) which is sandwiched between 211 and 221 feeds out the necessary amount corresponding to the i1J base π of the needle F (7).On the other hand, when the needle (7) is retracted, the operating rod (9) At the same time, the rank part (16) also moves backward, so the pinion (19) rotates in the opposite direction, but the spring 18)K pushes it backward and connects with the yarn feed gear (2o) on the n-F side, so both feed gears t20 ] t211 n stop and pile yarn (2 no pulls backward n, no words.

While moving this device along the area that requires repair (130), perform a supplementary examination by forming a pile as described above, and use the same method to perform a supplementary examination on the base fabric. Any pattern can be formed by forming piles according to the original drawing. In that case, the holes in the base fabric made by the needles are small, and a false twist structure is formed.
5. Of course, the back tightening is also done properly.

In the above embodiment, the air cylinders t4) and t5 were used as the two-stage j31, but this does not apply to the air cylinders t4), t5, which can be used for pressure type, electromagnetic type, crank type, etc. -1
All you have to do is find a suitable method. Also, the thread sending mechanism...
15) is not limited to the one using the upper F gear, tol 1211 k, but it may be one that sends out the required amount of yarn 1't2 when the needle (7) is +jij jin, but does not pull back when retracting.

As is clear from the above, the repair and mosaic-forming device according to the present invention has the following properties: A: During the Ippyo-fuchin and moguchi formation, the holes in the π base fabric are small and the base fabric is broken. Pile yarns are less likely to shift from the difficult holes 1-2. Immediately 2 Conventional pipe-shaped needles, especially those through which a bellow passes, have a large outer diameter and a hole drilled in the base fabric.
In contrast to this f1π, in the present invention, the needle is pipe-shaped and has a thin rod-like shape similar to that used when making carpets, and in addition, the needle has a concave groove extending to the tip of the needle in the shape of 1i.
At t-, engage the spatula there and make the slide IW1 town pot. Therefore, it is now possible to perform the backward speed +r+ independently without any problem while leaving the needle on the needle, and by combining the two, it has become possible to reduce the sturdiness and the holes in the base fabric.

tB] The special feature of Tuftetsu F carpet is the twisted structure π, which gives rise to the original sleeve. In other words, the tafted fabric has a false-twisted structure in which the sewing direction is π pair [7 slightly twisted π twists]. The pipe-shaped needle also has V〕,
Because the pile yarn cannot be twisted (yellow and false-twisted), the texture of the supplementary part is different from (also), and the carpet product fl [I value has been lowered. Next, set the needle with a thread hole so that the axis of the thread hole faces slightly toward the sewing direction.
By applying a false twist structure to the pile made of W, it is possible to repair the original shape in the same manner as when splitting.

[C] Tighten the pile yarn firmly. In other words,
Just insert the base fabric π needle and see the entire pile shape.
The slack in the pile threads can cause pile piping to occur or the pile to be loose, so the hook called a looper tightens the thread at 471.

However, conventional repair equipment did not have a device that could raise the tension as much as possible, and the piles became unreliable during the repair work.

In contrast to this method, according to the pulling method of the present invention, when the latch is holding the pile yarn on the front side of base A, the movable ring is also retracted when the needle is retracted. Pull the pile yarn towards the bottom by π backwards. In this way, by tightening the threads each time VcZ<Ile is formed, all the piles become uniform, π, and there is no muck on the back side of the base fabric, and the pile does not come loose during supplementary work or pattern formation, making it firm. .
