The beam is sent to the tension adjustment means 107, and is rotated by the core rotation drive means 102, so that the beam
It is wound up by CA.

FIG. 4 shows a conventional rewind-only device 117,
The fabric W guided from the core rotation driving means 109 for rewinding and rotating the beam CA to the fabric deriving means 110 via a plurality of guide rolls 111 is shaken off from the swinging arm 113 and folded into the carry-out cart 114. and stored.

[Problem that the invention aims to solve]

As mentioned above, in the beam dyeing process, the winding-only device 100 and the unwinding-only device 117 are used in the winding process and the unwinding process of the fabric W, but each requires a separate installation location. .
Particularly in the case of small-lot production, having to occupy such a large installation space is uneconomical because the floor space of the factory cannot be used effectively and equipment costs are incurred for each.

The purpose of this invention was to realize a rational winding and unwinding system that realized the integral structure of the winding mechanism and unwinding mechanism in the same device, thereby making effective use of the installation area and saving equipment costs. The purpose is to provide equipment.

[Means for Solving the Problems] The device for winding and rewinding a spread fabric of this invention is one in which a fabric winding mechanism and a fabric rewinding mechanism are integrally constructed.

The fabric winding mechanism includes a cloth introducing means for introducing a spread cloth, a spreading/centering means for spreading and/or centering the cloth introduced by the cloth introducing means in the width direction, and a cloth winding mechanism that controls the tension of the traveling cloth. It consists of a tension adjustment means that detects and adjusts the tension to a set tension, and a core rotation drive means configured to be able to rotate in forward and reverse directions and grips both ends of the core around which the fabric is wound, while the fabric rewinding mechanism includes: It consists of the core rotation drive means and a cloth deriving means for sending out the rewound cloth via a guide roll, and a treatment liquid drip receiving cover is provided between the cloth winding mechanism and the cloth rewinding mechanism. It is something that

[Effect]

The fabric to be treated, such as dyeing, is introduced from the fabric introducing means, and is spread and centered in the width direction by the spreading/centering means. The spreading/centering means may perform only one of spreading and centering. In addition, the tension of the running fabric is detected by the tension adjustment means,
The rotation of the winding core rotation drive means is controlled so that the set tension is achieved. As a result, the fabric is wound with uniform tension around the core set in the core rotation drive means.

After winding, the fabric is transported to a processing device such as a dyeing machine, where it is subjected to processing such as scouring, bleaching, or dyeing.

After this treatment, the treated fabric is rewound by the core rotation drive means and sent out to the next process by the cloth delivery means.

However, simply integrating the fabric winding mechanism and the fabric unwinding mechanism will cause the above unwinding to occur due to dripping of the treatment liquid contained in the fabric and falling of fuzz, thread waste, etc. that occur in the unwinding process. Since this will have an adverse effect on the fabric set in the winding process and on the respective means constituting the fabric winding mechanism, a cover is provided to receive the dripping of the treatment liquid.

The treatment liquid drip receiving cover 75 is formed in a roof shape by a pair of opposite sloped plates 75a and 75b below the path of the fabric W2 composed of the guide rolls 61a to 61e, and is attached to the frame 20 by a mounting member. (not shown). Each of the inclined plates 75a and 75b is formed wider than the fabric W2, has rising pieces on both sides in the width direction to prevent the fabric from running down, and is provided with a gutter 76 along the lower end of the slope. Each gutter 76 has a flow slope with a downspout (not shown) connected to the lower end of the slope.

The operation of the above configuration will be explained. Fabric W introduced into the fabric introduction means 30 from the fabric roll R of the supply cart 3
1, spreading and centering are performed by the first spreading means 51 of the spreading/centering means 50,
The liquid is further spread by the second and third spreading means 54, 54A and guided to the liquid removal means 70.

Depending on the type of fabric W1, the second spreading means 54
Thereafter, it is immersed in a dipping tank 55A via a guide roll 53c and guided to a third spreading means 54A.

At the point where the fabric W1 leaves the liquid removing means 70,
The tension is detected by the detector 56A of the tension detector 56, and the rotation speed of the motor 15 of the winding core rotation drive means 10 is controlled based on the detection signal so that the tension becomes the set tension. As a result, the fabric W1 is wound around the winding core C with a constant tension. Furthermore, the fabric W1 is spread and centered by the spreading/centering means 50, so that the fabric W1 is wound around the winding core C in a wrinkle-free spread state with the selvages aligned.

The core C that has been completely wound is loaded into a processing tank of a beam dyeing machine (not shown) by a transport means such as a crane, and the fabric W1 is subjected to processing such as refining, bleaching, or dyeing. When the process is completed, the winding core C is set in the winding core rotation drive means 10 again.

The treated fabric W2 of the set winding core C is
The fabric is rewound by reverse rotation (in the direction of arrow B) of the core rotation driving means 10 and guided from each guide roll 61a to 61f to the fabric deriving means 40. The fabric W2 guided to the fabric delivery means 40 is sent out by the rotation of the drive roll 47, and is stored in the carry-out cart 4 while being folded by the swinging of the swinging arm 42.

While the fabric W2 travels along the path defined by the guide rolls 61a to 61f, the processing liquid contained in the fabric W2 may drip, or fluff, thread waste, etc. may fall, but the falling processing liquid, etc. may not be processed. The liquid is received by the droplet receiving cover 75 and discharged from the gutter 76.

In each of the embodiments described above, the cloth extracting means 40 is constituted by a shaking device, but it is also possible to directly extract the cloth without shaking it. The winding core C is not limited to one used for beam dyeing, but may be used for various other types of processing.

[Effect of idea]

The device for winding and rewinding a spread fabric of this invention has a fabric winding mechanism and a fabric rewinding mechanism integrally constructed by a dual-purpose frame, and a winding core rotation drive means that is used for both winding and unwinding. Therefore, even though the device is equipped with both a fabric winding mechanism and a fabric rewinding mechanism, it is extremely compact and can be installed in almost the same space as one conventional dedicated device. It is possible to reduce equipment costs. This is particularly effective in small-lot production where winding and unwinding do not need to be performed at the same time. In addition, since a treatment liquid drip receiving cover is provided, the fabric set in the winding process and the means constituting the fabric winding mechanism can be removed by falling of the treatment liquid, fluff, thread waste, etc. in the unwinding process.
