Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cutting process for a cylindrical fabric, a process for unfolding the cut fabric, and a process for stretching the edge of the cut fabric when it curls. A fabric winding device and a fabric winding method capable of successively performing a correction process, a process of gumming the selvage, and a winding process of the gumming-treated fabric, and a fabric sel with gumming. It is related to the processing mechanism.

[Conventional technology]

After the circularly knitted cylindrical fabric is manufactured, it is cut to develop a flat fabric, which is then wound into a roll and transferred to a rolling (unwinding) process as a raw fabric roll. In this series of fabric handling processes, the manufacturing process for cylindrical fabrics and the winding and rolling processes for flattened fabrics have traditionally been carried out by separate companies. Generally, the distribution process was such that the company that carried out the stripping process delivered the raw rolls to the company that carried out the spreading process.

On the other hand, in the winding process for flat cloth, a method is adopted in which rotational force is applied to the paper tube that serves as the core and the flat cloth is pulled while being wound. (edges in the width direction of the cloth) may hang and curl. However, it is not possible to simply wind up a fabric with curled edges. Conventionally, for fabrics that cause such curls, the company that performs the winding process applies gumming treatment to the edges of the fabric to flatten the curled edges of the fabric, and the fabric that has been corrected in this way is then It was winding up. In this case, the gumming process involves flattening the curled selvage edge and then applying glue that hardens upon drying at regular intervals on the selvage edge. It is kept flat.

[Problem to be solved by the invention]

However, in recent years, due to the diversification of fabrics and patterns, there has been a tendency to produce small batches of rolls of the same type of fabrics and patterns. It is uneconomical for each company to have separate companies to carry out the manufacturing process and winding process of cylindrical fabrics, and a company to carry out the spreading process, as each company has to go through a complicated distribution process. It cannot be said that the system is able to adequately respond to customer requests. Therefore, if at least a fabric spreading company has a device that can easily gumming and winding fabric, it would be convenient to easily produce small-lot raw fabric rolls.

In addition, the conventional gumming process described above was performed by applying glue to the edges of the fabric, so
When the glue dries and hardens, it is inevitable that the areas to which the glue has been applied will be thicker by the thickness of the glue layer than the areas to which no glue has been applied. Therefore,
As shown in Fig. 9, in the raw fabric roll R wound up with gumming-treated fabric, the glue-coated area a is bulkier than the non-glued area b, and the raw fabric roll R tends to have a tapered shape. In addition, when unraveling is performed by rotating such a roll of tapered material and letting out the fabric, there is a difference in the width of the unwinding between the edges and the center of the fabric, making it smooth and good. There was a problem that it was difficult to solve the problem.

The present invention has been made in view of the above-mentioned circumstances and problems, and provides a simple winding device and raw material that can continuously and efficiently perform cutting, unfolding, gumming, winding, etc. of cylindrical cloth. It is an object of the present invention to provide a winding method that prevents a non-roll from becoming tapered, and an edge edge processing mechanism that can perform reliable gumming processing.

The cloth winding device according to the second invention applies a tensile force in the width direction to the flattened cylindrical cloth to widen the width of the cylindrical cloth, and then rolls the cylindrical cloth in the width direction. One end edge is cut to obtain a two-folded piece of fabric, and after this two-folded piece of fabric is unfolded into a flat state, a treatment liquid for gumming is sprayed on the edge of the piece of fabric, and at the same time as this spraying, the treatment liquid is The spraying pressure is applied to the edge of the edge to stretch the curled edge of the edge, and then, when the treatment liquid sprayed on the edge of the edge is not yet dry, the fabric is wound into a roll shape.

〔Example〕

FIG. 1 is an explanatory diagram showing the overall configuration of a cloth winding device according to a first invention and a cloth winding method according to a second invention.

The above winding device is a width adjustment mechanism 1 for a cylindrical fabric T.
, a cutting mechanism 2 for the cylindrical fabric T, a unfolding mechanism 3 for the cut fabric T, an edge processing mechanism 4 for gumming the flat fabric T', and a winding mechanism 5 for the flat fabric T'. Guide rollers 61 to 68 that guide the feeding of the cylindrical fabric T or flat fabric T' between the mechanisms 1 to 5, and widening rollers 71 to 68 that apply a widthwise spreading force to the flat fabric T'. 74, several types of drive rollers 81 to 84, and an illumination box 9 for fabric inspection.

FIG. 2 shows the tentering mechanism 1 and the cutting mechanism 2. The width adjustment mechanism 1 has a pair of guide rods 1 with good sliding properties attached to a post 11 erected on a machine frame B (not shown).
2 and 13 are installed vertically, one guide rod 12 is attached to the post 11 via a mounting bracket 14.
The other guide rod 13 is attached to the post 11 via upper and lower telescopic rods 15, 15. Therefore, when the other guide rod 13 is moved in parallel by expanding or contracting the telescopic rods 15, 15, the mutual distance between the pair of guide rods 12, 13 is adjusted to increase or decrease.

As shown in FIG. 1, a circularly knitted cylindrical cloth T is suspended from above a saddle-shaped guide plate 10 and fitted into a pair of guide rods 12 and 13 as shown in FIG.
The feed is applied by drive rollers 81 and 82.
Further, the mutual spacing between the pair of guide rods 12 and 13 is adjusted according to the width dimension of the cylindrical cloth T.
Therefore, a tensile force in the width direction is applied to the cylindrical fabric T by the pair of guide rods 12 and 13, and due to this tentering, the cylindrical fabric T is tensioned in the width direction and becomes in a state where there is no slack. .

The cutting mechanism 2 has the function of vertically cutting one end edge in the width direction of the cylindrical fabric T, which has been widthwise removed by the widthwise adjustment mechanism 1, and has the function of vertically cutting one end edge in the width direction of the cylindrical fabric T, which has been widthwise removed by the widthwise adjustment mechanism 1. Guide rod 12 on the other hand
It is arranged below the lower end of the cylindrical fabric T, and as the cylindrical fabric T is fed in the direction of the arrow, one edge of the cylindrical fabric T is cut. As the cutting mechanism 2, it is possible to employ a known cutter such as a rotary cutter or a knife-type cutter.

The unfolding mechanism 3 unfolds the cloth T'' which has been folded into a two-fold shape by the above-mentioned cutting into a flat state.
A pair of clamping rods 3 to prevent the cloth T'' from being disturbed
1, 32, a V-shaped frame 33, and a tensioning rod 34 extending upwardly in an arcuate manner astride the frame 33, and the clamping rods 31, 32 are arranged in an obliquely inclined position. , the frame body 33 is arranged approximately at right angles to the clamping rods 31, 32. According to this unfolding mechanism 3, FIGS.
As shown in the figure, the cloth T'', which is turned and sent upward by the guide roller 61, is held by the holding rod 31,
32 is the starting position for unfolding, and as it is fed over the frame 33, it is unfolded into a flat state. Then, the flattened fabric T' passes over the tensioning rod 34 and is tensioned in the width direction. Note that a tensile force is constantly applied to the cloth T' in the longitudinal direction by drive rollers 83 and 84.

The ear edge processing mechanism 4 has a pair of left and right nozzles 41, 42.
The processing liquid for gumming can be sprayed from these nozzles 41 and 42.
As shown in FIG. 5, one nozzle 41 is fixed to the sensor 43 via a mounting bracket 45, and a screw shaft 47 is screwed into a nut body 46 of the mounting bracket 45. As shown in FIG. The sensor 43 is a flat piece of cloth.
The nozzle 41 is constantly controlled to a constant position for detecting the edge t of T', so that the nozzle 41 is automatically set at the optimum position for spraying the processing liquid onto the edge t. That is, when one edge t of the cloth T' is not detected by the sensor 43, the screw shaft 47 is
rotates in a predetermined direction to move the sensor 43 to its ear edge t.
The nozzle 41 is moved to a position where it is detected, and the nozzle 41 moves together with the sensor 43. The other nozzle 42 is similarly fixed to the sensor 44 via the mounting bracket 47, and is constantly controlled to a constant position where the sensor 44 detects the other edge t of the flat cloth T' in the same manner as described above. As a result, the nozzle 42 is automatically set at the optimal position for spraying the treatment liquid onto the edge t. The sensors 43 and 44 of the ear edge processing mechanism 4 described above are examples of movable members in the third invention.

By the way, when a tensile force is applied to the flat cloth T' in the longitudinal direction as described above, the edge t of the cloth T' curls as shown in FIG. When performing gumming treatment on the curled ear edge t in this manner, it is necessary to stretch the curled ear edge t before the treatment. Therefore, in the ear edge processing mechanism 4, the curled ear edge t is stretched straight as shown by the arrow X in FIG. The processing liquid L is sprayed onto the straightened area. Therefore, according to the ear edge processing mechanism 4, both the action of straightening the curled ear edge t and the action of spraying the treatment liquid L in a mist onto the stretched ear edge t are performed simultaneously. Furthermore, when the treatment liquid L is sprayed from the nozzles 41 and 42 to the edge t of the fabric, the coating film becomes much thinner than that of conventional treatment liquids, and in some cases, the treatment liquid L may be applied to the fabric.
Since it is completely absorbed into the fabric T', there is no difference in thickness between the areas where the treatment liquid L was sprayed and the areas where it was not sprayed.

As the treatment liquid L for gumming, a known treatment liquid such as a two-part type in which a treatment liquid containing an active ingredient is diluted with a diluent can be used. And nozzle 4
It is a matter of course that a structure suitable for the type of processing liquid L is used for 1 and 42. Furthermore, the above-mentioned gumming treatment may be applied continuously to the edge t of the fabric T', or may be applied intermittently at regular intervals.

Fabric processed by gumming process by edge processing mechanism 4
T' passes over the illumination box 9 via guide rollers 63, 64 and a widening roller 71. As shown in FIG. 7, the width-expanding roller 71 is provided with spiral strips 72a and 72b that are wound in opposite directions on the circumferential surface of a body portion 71a and distributed to the left and right, and the rotation of the width-expanding roller 71 causes the fabric T' to be rolled into the spiral strips. By means of 72a and 72b, both side portions are pulled outward from the center. By applying the widening roller 71 to the cloth T' in front of the illumination box 9 in this way, the cloth T' passing over the illumination box 9 does not become loose or wrinkled, and visual inspection can be performed reliably.

The winding mechanism 5 includes a pair of driving rollers 83 and 84, and rotates the paper tube R1 on these rollers 83 and 84 to wind up the fabric T' onto the paper tube _R1 in a roll shape, and rolls the fabric T' onto the paper tube _R1 . This is to create an anti-roll R. This winding mechanism 5 and the lighting box 9
A plurality of guide rollers 65 to 68 and width widening rollers 72 to 74 are arranged between the two to guide and widen the cloth T'. Note that the winding mechanism 5 is not limited to the illustrated configuration example, and may be of a type in which, for example, a paper tube is directed to a rotating shaft to create a roll of raw material.

The treatment liquid L is attached to the edge t of the cloth T' wound up onto the paper tube _R1 by the winding mechanism 5 due to the above-mentioned gumming process. This treatment liquid L is applied even if the cloth T' is dried (naturally dried or forcedly dried with hot air, etc.) before it is wound up onto the paper tube R ₁ by the winding mechanism 5 or is not dried yet. good. In the case of undried, the above treatment liquid L is applied to the ear edge t.
It is sprayed onto the cloth to form a very thin film (in some cases, it is absorbed into the fabric of the cloth T′ and becomes thin), and when the cloth T′ is wound into a roll shape, Due to the synergistic effect of the drying treatment liquid L being applied to the fabric by the pressing force between the laminated fabrics, there is a difference in thickness between the areas to which the treatment liquid L is attached and the areas to which it is not attached. It will no longer occur. Therefore, as shown in FIG. 8, the portion a' to which the processing liquid L is attached does not become bulky, and the raw roll R does not become tapered. In FIG. 8, b' indicates a portion to which the processing liquid L is not attached. Furthermore, even when dry, the treatment liquid L is sprayed onto the edge t to form a very thin film (in some cases, it is absorbed into the cloth of the cloth T', resulting in a thin film). ), the portion a' to which the processing liquid L is attached does not become extremely bulky unlike in the conventional case (see FIG. 9).

〔Effect of the invention〕

The winding device for cloth according to the first invention can be constructed by arranging in this order a width adjustment mechanism, a cutting mechanism, a unfolding mechanism, an edge processing mechanism, and a winding mechanism for a cylindrical cloth, and each mechanism can be arranged in this order. According to the first invention, a series of steps from cutting a cylindrical fabric to winding a flat fabric to obtain a raw fabric roll can be carried out efficiently, continuously, and reliably. It is now possible to provide a simple fabric winding device that is capable of. In addition, it will now be possible for companies that carry out the fabric spreading process to easily produce raw fabric rolls, improving economic efficiency by simplifying the distribution process for fabrics, and creating a system suitable for the recent small-lot production of fabrics. becomes possible.

According to the second invention, in addition to being able to perform the above-described series of steps efficiently and continuously, there are the following significant effects. That is, in this invention, when the gumming treatment liquid sprayed on the edge of the cloth is not dried, the cloth is wound into a roll shape.
The above treatment liquid is sprayed on the edge of the selvage to form a very thin film (in some cases, it is absorbed into the fabric of the fabric and becomes thin), and when the fabric is wound into a roll. Due to the synergistic effect of the undried processing liquid being applied to the fabric by the pressing force of the stacked fabrics, there is a difference in thickness between the areas to which the processing liquid is attached and the areas to which it is not attached. This has the effect that it is less likely to occur and the raw roll is less likely to become tapered.

According to the third invention, since the nozzle that sprays the processing liquid for gumming is fixed to a movable member whose position is controlled so that it always corresponds to a constant position with respect to the feeding path of the cloth, the processing liquid is sprayed. The location is set with high precision to the edge of the fabric. Therefore, there is an effect that the curled ear edge is reliably stretched by the jetting pressure of the processing liquid, and the treatment liquid is reliably sprayed onto the stretched ear edge.
