Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a fabric processing apparatus in which a long cloth is coated with a treatment liquid using a pad and dried with hot air. This device is characterized by cleaning means for a large number of rollers provided between the rollers, and is used in the paddash dry dyeing process of fabrics and the resin processing process.

(Prior art) As a fabric processing device, there is a padder that applies a processing liquid such as a dye liquid or a resin processing liquid to the fabric, and a fabric impregnated with this processing liquid is wound around a number of guide rollers and transported. and a hot air drying device configured to dry with hot air, and while the guiding cloth connecting the fabrics passes through the padding and the hot air drying device, the padding is washed and the processing liquid is exchanged, and A large number of rollers, from the expander roller above the processing liquid tank to the guide roller at the exit of the drying device, were wiped with a guiding cloth to remove the processing liquid that had been transferred and adhered to the surface from the fabric of the previous lot. something is known.

(Problems to be Solved by the Invention) When the fabric impregnated with the processing liquid moves through the processing equipment, the above fabric meanderes slightly due to various factors, so it is difficult for each roller after the expander roller to The treatment liquid adhered irregularly over an area slightly wider than the width of the fabric, and wiping with the guiding cloth was incomplete. In particular, when a guiding cloth narrower than the above-mentioned cloth is used, the treatment liquid adheres to both the left and right sides of the rollers, and is left behind on each of the above-mentioned rollers without being wiped off. Therefore, when the fabric after the lot change passes, the treatment liquid of the preceding lot left on the roller is transferred to the fabric of the subsequent lot, resulting in a problem that the fabric of the subsequent lot is stained.
Attempts have been made to use a wide-width guide cloth, but in this case, a guide cloth that is wider than the fabric to be processed must always be prepared, which is extremely troublesome.

This invention makes it possible to wipe off dirt on each roller even when using a guide cloth narrower in width than the fabric for processing, thereby preventing the fabric from becoming stained.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a cloth seam detection device and a cloth swinging device that can make the running cloth meander from side to side on the entrance side of the padder. A cloth seam detection device detects the front and back seams of the guiding cloth, and a cloth swinging device is activated for this guiding cloth.

The above-mentioned cloth swinging device swings the running cloth to cause meandering, and the direction of the swing may be either in the front-rear direction or in the width direction of the cloth, for example, in the center of the cloth. Guide rods and guide rollers are arranged back and forth on a rocking table formed to be able to swing back and forth with respect to a fulcrum, and fabrics and guide cloths are wound around these in a staggered manner, and the rocking table is rocked back and forth. There are also types that have a pair of upper and lower cross guider rollers on both sides in the width direction, which have the function of pulling the fabric in the width direction, and whose nip portions are opened and closed alternately on the left and right sides.

(Conventional) When the front end of the guiding cloth is detected by the cloth seam detection device, the cloth swinging device that can make the running cloth meander from side to side starts operating, so the guiding cloth starts meandering from side to side. do. Therefore, each roller from the pad to the outlet of the hot air drying device is wiped over a wide area with the above-mentioned guiding cloth, and dirt attached to these rollers is removed over a wide area. Then, when the rear end of the guiding cloth is detected by the cloth seam detection device,
Since the operation of the swinging device is stopped, the fabric following the guide fabric is transferred without meandering. Thus, cleaning of the pad and liquid replacement are performed in the same manner as in the past, from when the joint at the front end of the guide cloth is detected until when the joint at the rear end is detected.

(Example) In Fig. 1, F is fabric, 20 is Patsuda, 3
0 is a hot air drying device, and the fabric F is sent to the fabric swinging device 10 via tension rods 1, 2, 3 and a cross guider 4, and then sent to the fabric swinging device 10 via a fabric seam detection device 5 and a guide roller 6. Sent to Patsuda 20.

The fabric swinging device 10 described above is equipped with a plate-shaped swinging table 11 that is long in the width direction of the fabric F at the part where the fabric F moves downward on the entrance side of the padder 20 (see Figs. 2 to 4). reference). This rocking table 11 is supported at its center by a fixing bracket 12 and a horizontal support shaft 13, and at one end (the right end in FIG. 2), the tip of a piston rod 14a of a rocking air cylinder 14 attached to the frame is connected. One end of each of two tension coil splinders 15, 15 is attached to the other end, and the other end is extended in the opposite direction and fixed to the frame, and by the operation of the swing air cylinder 14, the swing table is 11 is designed to swing up and down, in other words, back and forth in the direction of movement of the fabric F.
