[Detailed Description of the Invention] (Industrial Application Field) This invention provides a cloth pad dry dyeing device,
The present invention relates to a fabric processing apparatus, such as a pad steam dyeing apparatus and a resin processing apparatus, for applying a processing liquid such as a dye liquid or a chemical liquid to a fabric, and then subjecting the fabric to a heat treatment such as drying or steaming.

(Prior Art) In a fabric processing apparatus, for example, a pad dry dyeing apparatus, the main body of the processing apparatus is composed of a dye bath, a squeezing roller, an infrared pre-drying device, and a hot air main drying device. Fabric supply side of dye bath)
An inlet device for supplying fabric is installed on the side, and a shake-off device as an outlet device is installed on the outlet side (fabric discharge side of this drying device), and a guide cloth interposed between the fabrics before and after the color change is installed. A device is known in which various operations necessary for the above-mentioned color change, such as exchanging the dye in the dye bath and moving the shake-off roller in the shake-off device, are performed while passing through the main body of the processing device. There is. That is, fabric seam detectors are installed on the inlet side of the dye liquor tank and on the outlet side of the main drying device, and the seam between the rear end of the fabric of the preceding lot and the front end of the guided fabric is detected by the seam detector on the inlet side of the dye liquor tank. Then,
The timer starts operating, and when the above-mentioned joint comes out of the dye bath after a predetermined period of time, the color changing device is activated to drain the dye bath, clean it, and supply new dye bath. Next, when the above-mentioned seam reaches the exit-side seam detector of this drying device, the timer starts operating again, and when the above-mentioned seam reaches the shaking-off position for processed fabric after a predetermined period of time, it is shaken. The dropping device moves to the shaking-off position for the guiding fabric, and the guiding fabric following the above-mentioned joint is shaken off to the guiding fabric carrier, and furthermore, the joint between the trailing end of the guiding fabric and the front end of the fabric of the subsequent lot is dyed. When the seam detector on the liquid tank inlet side is reached, the timer starts operating again, and when the seam at the rear end of the guiding cloth reaches the shaking-off position of the guiding cloth after a predetermined period of time has elapsed, the shaking-off device is returned to the shake-off position for processed fabrics, and subsequent lots of processed fabrics are shaken off to the processed fabric transport vehicle.

(Problems to be Solved by the Invention) In the conventional apparatus, the time required for the joint at the rear end of the preceding lot, that is, the front end of the guiding cloth to pass through the joint detector at the inlet side of the dye liquor tank and exit the dye liquor tank, The time required for the seam to pass through the outlet side seam detector of this drying device and reach the shake-off position for processed fabric, and the time required for the seam at the rear end of the guiding fabric, that is, the front end of the subsequent lot, to pass through the seam detector on the exit side of this drying device. The time required from passing through the detector to reaching the shaking-off position for the guiding fabric is measured in advance, and the fabric and guiding fabric are run at the same speed as during this measurement and controlled by a timer. Therefore, if the guiding cloth is run at a low speed and the fabric for processing is run at a high speed, and the running speed of this fabric is changed depending on the type, the timer settings must be changed, and the The adjustment work was extremely troublesome. Attempts have been made to control the timer according to the fabric speed, but in this case, a separate control device is required, resulting in a high cost of the device.

(Means for solving the problem) It consists of a processing device main body for applying a processing liquid to the fabric and performing drying or heat treatment, and an inlet device and an outlet device installed before and after the main body of the processing device. In a fabric processing apparatus, the processing liquid exchange and other conditions necessary for the lot change are performed while a guide cloth interposed between the fabrics before and after the lot change passes through the main body of the processing apparatus, A seam detector is installed on the inlet side of the processing equipment main body,
Further, each of the processing apparatus has a fabric length measuring device for the traveling fabric at an arbitrary location in the main body, and causes the fabric length measuring device to start measuring the length by detecting a seam by the seam detector,
It is also characterized in that it is equipped with a programmable cotton roller for inputting the output signal of the fabric length measuring device and causing the above-mentioned condition changing operation to be performed when the running length of the fabric reaches a predetermined length.

In this invention, the process liquid exchange and other condition changes necessary for changing lots include draining the process liquid remaining in the process liquid tank at the end of processing of the preceding lot in the pad dry dyeing apparatus, cleaning this process liquid tank, Operation of supplying processing liquid for subsequent lots;
The action of moving the mobile shake-off device on the exit side, draining the chemical solution remaining in the chemical bath after finishing the processing of the preceding lot in the pad steam dyeing device, cleaning this chemical bath, and discharging the chemical solution remaining in the chemical bath after finishing the processing of the preceding lot in the pad steam dyeing device. The operation of supplying chemical liquid to the steamer outlet, draining the water remaining in the seal tank at the steamer outlet, cleaning this seal tank, and supplying new water, These operations include draining the remaining resin processing liquid, cleaning this liquid tank, and supplying resin processing liquid for subsequent lots.

(Function) The length of the fabric between the seam detector installed on the inlet side of the processing equipment and the location where the seam should be located when changing conditions for lot change is measured in advance and If the set length is stored in the program controller, the fabric length measuring device will start measuring the length as soon as the front and back seams of the guiding fabric pass through the seam detector, and the running fabric length will be stored in the program controller. The running cloth length is successively compared with the set cloth length, and when the running cloth length matches the set length, a predetermined condition change is performed.

(Example) In the drawings, 1 is a fabric transport vehicle for stacking the fabric F in a spread shape, 2 is an inlet device, 3 is a dye tank, 4 is an infrared pre-dryer, 5 is a hot-fluid type main dryer, Reference numeral 6 designates a mobile shaking-off device, 7 a fabric transport vehicle for processed fabric F, and 8 a fabric transport vehicle for guiding cloth, in which the fabric F loaded on the fabric transport vehicle 1 on the supply side is transferred to the entrance device 2. After being taken out and spread, it is sent to the dye liquor tank 3 via the lower guide rollers 2a and 3a, where it is immersed in the dye liquor, and then it is uniformly squeezed by a pair of squeezing rollers 9. Afterwards, it is sent to an infrared pre-dryer 4 via a guide roller 4a, where it is rapidly pre-dried to the extent that migration of the dye solution does not occur, and then passed through a guide roller 4b.
The fabric is then sent to the main drying device 5 for main drying, and then sent from the guide rollers 5a and 6a to the mobile shaking device 6, where it is shaken off by the fabric carrier 7. Then, the fabric F of the preceding lot and the fabric F of the subsequent lot
When the guiding cloth (not shown) connected to It is shaken down by the fabric transport vehicle 8.

A seam detector 10 for the fabric F is provided adjacent to the guide roller 2a on the entrance side of the dye bath 3, and a fabric length measuring device 12 is provided to the squeezing roller 9 via a transmission mechanism 11. 10 is connected to a program controller 13 by a circuit 10a, and the fabric length measuring device 12 is connected to a program controller 13 by a circuit 12a. This program controller 13 causes the fabric length measuring device 12 to start operating when the seam detector 10 detects a seam in the fabric F, and when the traveling length of the fabric F reaches a predetermined length, it issues an output signal to measure the fabric F. It commands to change the speed, change the color of the dye bath 3, and command the movement of the mobile shaking-off device 6.

In the above structure, the preceding fabric F and the following fabric F are connected by a guiding cloth and supplied from the fabric transport vehicle 1 to the inlet device 2, pad dry dyeing of the preceding fabric F progresses, and this fabric F and the guiding fabric are connected. When the seam of the cloth reaches the seam detector 10, the seam is detected and the cloth length measuring device 12 starts measuring the length. Then, the above seam passes through the dye bath 3, and the guide roller 3 above it passes through the dye bath 3.
When point b is reached, a series of operations such as draining the remaining dye liquor from the dye liquor tank 3, cleaning, and supplying the dye liquor for the subsequent rod are started in response to instructions from the program controller 13. Incidentally, these series of operations can be performed by, for example, the apparatus described in Japanese Patent Application No. 70776/1983.

Next, when the joint between the fabric F of the preceding lot and the guiding fabric passes through the infrared preliminary dryer 4 and the main dryer 5 in order and reaches the fabric outlet 6b of the mobile shaking-off device 6, the sprung controller 13 In response to this command, the moving motor (not shown) of the mobile shaking-off device 6 is driven, and the mobile shaking-off device 6 is moved to the chain line position 6, and guided to the fabric carrier 8 for the cloth. The cloth is shaken off.

When the color change in the dye bath 3 is completed and the seam between the guiding fabric and the fabric of the subsequent lot reaches the seam detector 10, the fabric length measuring device 12 starts measuring the length anew, and the seam is located at the chain line position. Fabric outlet 6b of the mobile shaking-off device 6
When this is reached, the mobile shaking-off device 6 is returned to the solid line position 6, and the subsequent lot of fabric F is shaken off onto the fabric transport vehicle 7 for processed fabrics.

In addition, when switching the fabric speed between high speed and low speed, when the seam between the fabric F of the preceding lot and the guiding fabric reaches the seam detector 10, the high speed is switched to low speed, and when the seam between the fabric F of the preceding lot and the fabric F of the succeeding lot is When the seam leaves the main dryer 5, the low speed is switched to high speed.

(Effect of the invention) The running length of the fabric is measured based on the point in time when a seam detector installed on the inlet side of the processing equipment body detects a seam of the fabric, and when the fabric has traveled a preset length, Since it is designed to change conditions such as color change, even if the running speed of the fabric is changed, the above conditions can be changed without any problem, and no timing adjustment is required. Therefore,
The fabric for processing is passed through the processing equipment main body at high speed,
By passing the guiding cloth at a low speed, the length of the guiding cloth can be shortened. In addition, only one seam detector needs to be installed on the inlet side, and there is no need to install it inside the processing device itself, so the processing speed is lower than when multiple seam detectors are installed along the fabric travel path. The interior of the device body is enlarged, and the seam detector is not contaminated with dye liquor or other processing liquid, and the fabric is not soiled.
