Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fabric which is continuously transferred in a predetermined apparatus in order to continuously perform pretreatment, posttreatment and the like on a long fabric. The present invention relates to a cloth spreading centering device capable of constantly controlling the transfer to the center of the transfer path and ensuring the spread state of the transfer cloth.

[Prior Art] For example, a long fabric produced industrially is subjected to quiking, desizing, scouring, bleaching, dyeing, washing, or other liquid treatment.
In the case of continuous operation, it is necessary to guide the long cloth by a guide roller of a predetermined facility device and continuously run it. During this continuous running, the fabric must be run continuously without being displaced from the predetermined position (center position) of the transfer path. The cloth transferred in terms of the uniform accuracy of diameter or the accuracy of quality of the cloth may be shaken in the axial direction of the guide roll. In an extreme case, the cloth may come off the guide roll or become a rope shape. There is a problem that continuous running in the spread state of becomes impossible. Therefore, a long fabric that should be run continuously,
In the transfer path that guides the guide roll to transfer
There is a centering device for automatically centering the running fabric so that the center of the fabric passes through the center of the transfer path.

[Problems to be Solved by the Invention] As this conventional means, for example, there are a cross guider, a roll guider, a flat guider, and the like. In order to hold the chopsticks,
By mechanically forcing a cross guider, a roll guider, a flat guider, or the like, for example, when a silk cloth or a woven cloth that is prone to be bent is centered, the cloth is bent or deformed. Good processing cannot be achieved. Further, since the cross guider is required to form at least two inclined guide rolls as one set and arrange the combined guide roll groups on both side ears of the cloth to be run, both of these guide rolls must be arranged. A space for arranging the guide roll group is required, and in a device with a small space, it is often impossible to install a cross guider. Further, since the centering of the cloth by the cross guider utilizes a mechanical operation, the mechanism is complicated and the durability and reliability are poor.

[Means for Solving the Problem] The present invention has been made by paying attention to such a conventional problem, and a large number of nozzles for ejecting pressured water toward a transfer cloth surface are arranged in a cloth transfer path. It is possible to perform centering without causing deformation such as loosing or bending of the cloth transferred by the water pressure ejected from these nozzles, and to generate the ear soup of the transferred cloth. It is to provide a spreading centering device that does not.

Further specifically describing the present invention, a water supply pipe extending in the width direction of the cloth is arranged in the cloth transfer path, and a large number of pressure water jet nozzles are arranged in the generatrix direction of the water supply pipe. The jet direction of the pressure water jet nozzles is inclined toward both sides of the fabric in a V-shape with the center part of the fabric as a boundary, and the amount of water or water pressure jetted from each of the nozzles is adjusted to the edge position of the running fabric. By adjusting the detection signal from the sensor that detects, the running cloth can be constantly corrected to the center, and the ear sowing of the cloth transferred by the water pressure sprayed from each nozzle can be regulated. It was done like this. Therefore, according to this, the centering and spreading of the cloth (prevention of ear winding) can be performed easily and surely by the simple structure in which a large number of pressure water nozzles are arranged in the cloth transfer path in the cloth width direction. There is.

[Examples] The present invention will be described in detail below based on examples shown in the drawings.

Reference numeral 1 is a cloth such as silk cloth or knitted material which is continuously processed and transferred, and the cloth 1 is carried from a pretreatment step by a conveyor 2. The cloth 1 that has been transferred is pulled up by the pulling roll 3, but at the time of this pulling up, centering is required to restrict movement to the center of the transfer path. Therefore, in the present embodiment, a pair of first shower nozzles 4 and 4 for applying pressure water to the front and back surfaces of the fabric 1 immediately after being pulled up from the conveyor 2 are arranged. This shower nozzle 4, 4
A sensor 5 for detecting the edge position of the rising fabric is arranged above the above, and pressure water is sprayed above this sensor 5 toward both the front and back sides of the rising fabric 1, especially to the ears. The second shower nozzles 6 and 6 for suppressing the soothing of the ears are arranged.

Next, the structures of the first and second shower nozzle structures and the sensor 5 will be described. The first shower nozzles 4 and 4 and the second shower nozzles 6 and 6 which are respectively installed opposite to each other.
Have the same structure, so only the structure of the first shower nozzle 4 will be described. That is, the shower nozzle 4 is provided with a flowing water pipe 7 extending in a direction parallel to the width direction of the fabric 1 and a large number of nozzles 8 which are spaced from each other in the longitudinal direction of both upper and lower sides of the flowing water pipe 7.
However, when viewed from a plane, these nozzles 8 have the water jetted from these nozzles with a partition 9 provided in the central portion of the flowing water pipe 7 as a boundary, as shown in FIG. It has a V shape and is inclined so as to be sprayed on the fabric surface. That is, the group of many nozzles 8 provided in the running water pipe 7 is configured so that water is jetted toward both ends of the cloth 1 with the partition 9 provided in the center of the running water pipe 7 as a boundary. It is divided into a left tilt nozzle group (a) and a right tilt nozzle group (b). The form of the water jetted from each nozzle 8 may be, for example, a rod shape as shown in FIG. 5 (a) or a fan shape as shown in FIG. 5 (b), and is set to either one by replacing the nozzle 8. However, if the cloth is silk cloth or knitted fabric, it is preferable to make it fan-shaped,
Less likely to bend the eyes. Electromagnetic valves 11 and 11 'are provided in each of the water supply pipe 10 for supplying water to the left inclined nozzle group (a) and the water supply pipe 10' for supplying water to the right inclined nozzle group (b). Reference numeral 12 is a pressure switch, and the solenoid valve 11 is opened / closed by the operation of the pressure switch.

Next, the sensor 5 will be described.
It has a pair of fillers 13 provided near both ears (edges) of the cloth 1 to be transferred, and normally, both ears of the transfer cloth 1 do not come into contact with the fillers 13 or barely come into contact therewith. The position of the filler 13 is set in (4th
See figure). Therefore, when the transfer cloth 1 is displaced in the cloth direction, the filler 13 operates, and as a result, the pressure sensor 14 operates and the pressure switch 12 operates.

The configuration of this embodiment is as described above. Next, its operation will be described. The first shower nozzles 4, 4 and the second shower arranged in the process of pulling up the cloth 1 sent by the conveyor 2. Spray water is sprayed from all the nozzles 8 of the nozzles 6 and 6 toward the front and back surfaces of the cloth 1. Therefore, the cloth 1 to be transferred is one shower nozzle 4,
4 and the second shower nozzles 6, 6 are pulled up while receiving the jet pressure water jetted. Normally, the transfer cloth is transferred at the cloth width direction center of the transfer path, but if the transfer cloth 1 is displaced in the width direction for some reason, the above-described filler 13 operates due to the deviation. The pressure switch 12 on the side operated by the operation of the filler 13 operates, and as a result, the solenoid valve 11 or 1 on the side operated
1 ′ works to stop the water supply to the nozzle 8. That is, the third
If the fabric 1 is displaced to the left side in the figure, the solenoid valve 11 on the left side closes to stop the water supply to the nozzle group (a), and the fabric receives the jet water pressure from only the right nozzle group (b). The position of 1 is corrected to the right, and the fabric 1 is moved to the center of the width direction and corrected. Similarly, when the cloth 1 is displaced to the right, the cloth 1 is automatically centered because the cloth 1 is repositioned to the left. Thus, the cloth that is constantly corrected to move to the center always receives the water pressure of the water sprayed from the second shower nozzle 6 when it is pulled up, so that the ear sopping of the cloth transferred by this water pressure is prevented, and the process proceeds to the next step. And will be transferred.

Therefore, according to this embodiment, the centering of the cloth transferred by receiving the pressure water jetted from the large number of nozzles is effectively and surely performed, so that the centering is restricted by the conventional mechanical power. In comparison, continuous transfer is possible without damaging or deforming the fabric,
Especially, it is effective for continuous transfer of the fabric which is likely to be loosened or bent. In addition, since it is possible to prevent the fabric that is transported by the water pressure jetted from the nozzle from rolling around and spread the fabric, it is particularly effective for the continuous transport of the knitted fabric that is apt to cause the bending.

[Effects of the Invention] As described above, the present invention provides, in a transfer path through which a long fabric is continuously pulled up and transferred, from a lower portion to an upper portion thereof
A first shower nozzle including left and right nozzle groups that spray pressured water in the left and right directions from the center of the cloth width on both front and back sides of the cloth, a sensor that detects both ear portions of the cloth to be transferred, and the cloth A second shower nozzle for spraying pressured water toward both side edge portions of the cloth to suppress the ear sopping of the cloth is sequentially arranged, and a signal from the sensor is supplied to the water supply pipe of the first shower nozzle. The fabric spreading centering device is provided with an electromagnetic valve that selectively stops water supply to either one of the left and right nozzle groups. Therefore, according to this, since the centering of the cloth transferred by the first shower nozzle and the sensor is performed effectively and surely, the cloth is damaged as compared with the conventional means in which the centering is restricted by the mechanical power. Further, it is possible to carry out continuous transfer without being deformed, and it is particularly effective for continuous transfer of a fabric which is liable to be bent or bent. Further, since it is possible to prevent the cloth that is transferred by the water pressure jetted from the nozzle from spreading and spread the cloth, it is possible to obtain the effect that it is particularly effective for the continuous transfer of the woven cloth that is likely to cause the bending.
