CONSTITUTION:Independently driven driving rolls 5 are disposed at fixed spaces in the lateral direction between a cloth introduction inlet 3 and a cloth outlet 4 in a wet heat treating chamber 1 retained in the hot and humid condition, and long cloth is suspended on the driving rollers 5 and transferred. The width of a droop formed at a droop forming part 7 is regulated by guide rollers 6, and gas in the treating chamber is blown off from gas nozzles 8 into the droop forming part 7 to keep the shaping of the droop forming part 7. The drooping length of the droop forming part 7 is detected by sensors 9A, 9B to control the rotating speed of the driving rolls 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long fabric in which, for example, in a moist heat treatment chamber in which moist heat is maintained, a fabric continuously supplied into the moist heat treatment chamber is suspended and shaped in a loop shape and transferred without tension. The present invention relates to a loop shaping transfer device.

[0002]

2. Description of the Related Art The inventor of the present invention desires a long fabric to which a predetermined treatment liquid is applied in order to perform, for example, pretreatment and dyeing treatment of a long fabric which is industrially produced and processed. We have conducted many years of research on a treatment method or a treatment apparatus for continuously performing the target wet heat treatment by sequentially passing through the wet heat treatment chamber in which the heat and humidity are maintained.

[0003] Among them, a device for continuously transferring the cloth passing through the inside of the wet heat treatment chamber without applying tension to the cloth, for example, a fabric texture processing device, a shrinking device, or a print. Like fabric,
For a device such as a print color developing device that cannot contact the guide roll with the print processing surface,
It is necessary to transfer the fabric without tension, and many developments have also been made for this tensionless transfer device.

[0004]

However, such a tensionless continuous transfer device is installed in a room where the hand is difficult to reach, for example, in a moist heat treatment room where high pressure or normal pressure wet heat is maintained. Since it is difficult to control the tension-free transfer condition of the fabric inside the chamber from the outside of the wet heat treatment chamber, the continuous tension-free transfer device transfers the fabric while suspending and forming the fabric in a loop at regular intervals. However, there has been a demand that it must be mechanically, continuously, and surely reliable.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to meet such a demand, and is a drive for vertically suspending and transporting a long fabric to an upper part of a moist heat treatment chamber where moist heat is retained. In a moist heat treatment apparatus in which rolls are arranged at a constant interval from the cloth introduction port of the moist heat treatment chamber toward the cloth ejection port, diffused air is blown inside the suspension forming fabric formed between the drive rolls and in the width direction of the fabric. The air-blowing nozzles are arranged, and the suspension forming fabric formed between the drive wheels is shaped by blowing air and further spread to ensure the formation of suspension (loop formation) of the fabric in the wet heat treatment chamber. Another object of the present invention is to provide a loop shaping transfer device for a long fabric that can improve reliability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in the drawings.

[0007] Reference numeral 1 denotes a wet heat treatment chamber in which high temperature and high humidity heat and humidity are held.
A fabric introducing port 3 and a fabric introducing port 4 for introducing and discharging the heat treatment into the wet heat treatment chamber 1 are formed.

At the upper part of the wet heat treatment chamber 1, drive rolls 5 are laterally arranged at regular intervals. Each drive roll 5 is rotated at a desired speed by each drive motor (not shown) provided for each drive roll.

Reference numeral 6 is a guide roll for guiding the cloth that is pulled up or hung down by each drive roll 5, and each drive roll 5 is guided by these guide rolls 6.
The suspension width a of the fabric to be suspended 7 is regulated between the two.

Reference numeral 8 denotes a gas nozzle for blowing gas (vapor) into the moist heat treatment chamber inside the suspension forming portion 7 formed by the drive rolls 5 and the guide rolls 6,
By the gas blowing force blown out from the gas nozzles 8, the suspension forming portions 7 are kept shaped and the cloth 2 is expanded in the width direction, so that the transfer cloth 2 is particularly wrinkled in the vertical direction. The suspended shape (loop) of the desired shape can be maintained without any trouble.

Reference numerals 9A and 9B denote a light emitter and a light receiver of an optical sensor for detecting the lower end position of each of the suspension forming portions 7, and a pair of the light emitter 9A and the light receiver 9 for each suspension forming portion 7.
B is provided, the hanging position of each suspension forming portion 7 is detected, and the drive rolls 5 are individually driven and controlled by the detection output to form each suspension formation formed in the wet heat treatment chamber 1. It is automatically adjusted so that the hanging position of the portion 7 is always a constant position.

Since this automatic sag adjusting mechanism can be constructed by a combination of a known optical sensor and control means for controlling the rotational speed of the drive roll by the output from the optical sensor, the detailed structure thereof will be described. The description is omitted.

The structure of the present embodiment is as described above. Next, the operation thereof will be described. The long fabric 2 supplied into the wet heat treatment chamber 1 is suspended 7 between the drive rolls 5.
Then, each drive roll 5 is rotated at a substantially constant speed to be transferred in a state in which each suspension formation 7 is kept in shape, and receives wet heat until it is sent out from the fabric outlet 4 of the wet heat treatment chamber 1. The target moist heat reaction treatment is performed.

In the present embodiment, in the suspension forming portions 7 of the cloth transferred in the wet heat treatment chamber 1, the suspension forming portions 7 are directed toward the inside of each suspension forming portion 7 in order to maintain (shape) the suspension formation. In order to receive the blowing force of the gas (vapor) from the gas nozzle 8, the cloth is, for example, an extremely thin cloth, or the cloth in a situation in which the cloth is easily attached to the peripheral surface of the drive roll 5 due to the humidity contained in the cloth. Even if there is, the trouble that the cloth is wound around the drive roll or the guide roll is prevented in advance, and the suspension forming portion 7 formed between the drive rolls is formed.
The fabric can be sequentially transferred while the shaping of the fabric is maintained, and the air blowing force causes the fabric to spread in the width direction of the fabric, which causes wrinkles in the vertical direction on the fabric that is continuously transported. No hanging, orderly suspension formation 7
The fabric is continuously transferred in this state.

The suspension forming portion 7 maintained between the drive rolls 5 is controlled by the degree of shrinkage of the cloth 1 which is heat-moisture treated.
When the hanging length of the drive roll changes, the amount of change in the hanging length is detected by the optical sensors 9A and 9B, and the rotation speed of each drive roll 5 is individually adjusted so that the hanging length is always constant. Since the hanging length of each suspension forming portion is automatically adjusted by the control, the suspension forming portion 7 having a stable shape (length) can be always maintained.

[0016]

INDUSTRIAL APPLICABILITY As described above, according to the present invention, the respective drive rolls, which are independently driven and have the long cloth hanging down at a constant interval, are provided above the indoor space of the wet heat treatment chamber where the wet heat is retained. Arranged at a constant interval from the cloth inlet of the chamber toward the cloth outlet, and further, the gas is delivered to the inside of each suspension forming portion of the cloth formed between the drive rolls and in the width direction of the cloth in a diffused state. Since it is a long cloth loop shaping transfer device that has a gas nozzle for detecting the hanging length of the suspension forming portion, and a sensor for controlling the rotation speed of the drive roll, the wet shaping is performed. The long cloth supplied into the heat treatment chamber has a gas pressure blown out from the gas nozzle, a sensor for detecting the hanging length of the suspension forming portion, and an output from the sensor for controlling the rotation speed of the drive roll. By a constant interval Orderly suspension forming unit is held in the transfer of wet heat treatment chamber while, whereby the effect that the loop transfer of interest (no tension transfer) is reliably performed is obtained.
