As a result, when air is supplied from the air supply connection port 114 and electricity is supplied from the connection terminal 116, the chuck 86 is opened and closed by operating the solenoid valve 94 by an electric signal. Further, when the air and electricity are not supplied, the air in the air tank 90 is used to utilize the mechanical valve 98.
Operates to open and close the chuck 86. That is, since the coupler 126 is connected when the chuck 86 grips the cloth W, the coupler 126 is connected when the chuck 86 separates the cloth W by closing the chuck 86 by the solenoid valve 94. Since it is not connected, the chuck is opened by the operation of the mechanical valve 98.

A solenoid valve 102 is connected to the air tank 90, and the solenoid valve 102 is connected to the solenoid valve 102.
The rotary actuator 82 is connected via the speed controller 192. A silencer 202 is connected to the solenoid valve 102. That is, when the chuck 86 grips the cloth W and peels the cloth W from the pin 14, the reversal is performed by operating the solenoid valve 102 and rotating the rotary actuator 82. The speed at which the chuck 86 is reversed is controlled by the speed controller 192. It should be noted that this inversion operation is performed in the state where the coupler 126 is connected.

However, unlike other sensors, a pair of left and right is provided,
This is because the movements of the couplers 126 and 128 are independent unless the positions of the docking members 106 and 108 are checked on the left and right sides, and the docking between the connection recess and the connection projection may shift.

Reference numeral 218 denotes a cloth removal sensor provided in the vicinity of the point A detection sensor 212, which detects whether or not the cloth W is removed and is moving together with the carrier member 54.

Reference numeral 222 is an operation unit of the control unit 194. The operation unit 222 operates the operation command of the apparatus and the rotation speed of the tenter motor 16 of the pin tenter 4.

(8) Operation of Chuck to Remove Cloth Hereinafter, the operation of the chuck 86 to remove the cloth W from the pin 14 will be described (see FIGS. 5 to 7).

The cloth W conveyed in the spread state to the tenter rail 10 rises upward along the inclined surface 160a of the cloth receiving plate 160 and reaches the position of the horizontal plane 160b. Then, it reaches the position of the chuck 86 in the opened state (see FIG. 5).

The cloth detection sensor 196 detects that the cloth W has come to the position of the chuck 86, and the rotary actuator 82 closes the grip portion 86b of the chuck 86, and the leading end of the cloth W is detected by the cloth detection sensor. 196 detects that the cloth W has come to the position of the chuck 86, and the rotary actuator 82 causes the grip portion 86 of the chuck 86 to be detected.
With b closed, the tip of the cloth W is gripped (see FIG. 6).

When the chuck 86 grips the cloth W, the rotary actuator 82 rotates the chuck 86 upward.
In the state of rotating the cloth W upward, the cloth W is pulled upward, and the cloth W is removed from the pin 14 (see FIG. 7).

A motor may be used instead of the rotary actuator 82.

(9) Mechanism for moving the chuck in the left-right direction
Concrete following describes the structure for moving the chuck 86, 88 in the lateral direction.

When the cloth W is conveyed, the width of the pair of tenter rails is changed according to the width of the cloth W. Therefore, it is necessary to move the positions of the chucks 86 and 88 for removing the cloth W accordingly. Especially chuck 8
Since the positions of 6, 88 need to be provided in the vicinity of the pin 14, the adjustment is delicate. The screw rods 66 and 68 are rotated by the width adjusting motor 150 via the crank rods 78 and 146. When the screw rods 66 and 68 rotate, the moving members 70 and 72 move symmetrically along the linear rails 60 and 62. This causes the chucks 86, 88 to move. In this case, the moving distance is detected by the rotary encoder 148 connected to the width adjusting motor 150. The signal output from the encoder 148 is the control unit 19
4, the moving distance is determined.

(10) Line Velocity Control The line velocity control will be described below separately.

The normal line speed for performing heat treatment in the heat treatment machine 5 (hereinafter referred to as normal speed) is 10 m /
Most are over minutes. However, when the cloth W is removed by the pull-out device 6 and guided to the shake-off device 8, the cloth W may not come off properly because the normal speed is too fast.
Therefore, when performing the cloth removal operation, the control unit 194 controls the transport motor 3 to reduce the normal speed to a line speed of 10 m / min or less (hereinafter, referred to as cloth removal speed).
Go to 02. When the normal speed is 10 m / min or less, the line speed is maintained as it is.

By the way, the line speed is, as defined above, the conveyance speed of the cloth W, and the cloth conveyance motor 3
The speed is determined by 02, and the speed of the endless chain 52 (hereinafter referred to as the chain speed) is determined by the chain motor 220. In addition, each guide roller 22, 24, 26, 28 and each chain wheel 30, 3
Since 2, 36 and 38 are coaxial but can be driven independently, the chain speed and line speed can be controlled independently. Then, as is clear from FIG. 2, the drawing device 6
The traveling distance of the cloth W (the distance shown by the solid line in FIG. 2) and the traveling distance of the carrier member 54 (the distance shown by the alternate long and short dash line in FIG. 2) are different from the cloth removing position to the shaking-off position. If the line speed and the chain speed are the same, the cloth W having a short traveling distance will be loosened. When the cloth W is loosened, the cloth W is wound around the guide rollers 22, 24, .... In order to solve this, if the line speed is made higher than the chain speed, unnecessary tension acts on the cloth W, or the cloth W comes off the carrier member 54.

Therefore, the drawing device 6 performs the line speed following type torque control with respect to the line speed and the chain speed. The control will be described below with reference to FIG.

Reference numeral 304 is a pulse oscillator for detecting the rotation speed of the cloth conveying motor 302, and outputs the signal to the pulse train converter 306.

Reference numeral 308 is a torque amount setting device. The torque amount set by the torque amount setting device 308 is determined by the type of cloth W to be conveyed.

Reference numeral 310 is a driver circuit for the chain motor 220, which inputs a speed signal and a torque signal from the pulse train converter 306 and the torque amount setting device 308, respectively. Incidentally. The driver circuit 310 includes a control unit 196.
Is also connected.

Next, the control method will be described.

When the cloth W is held by the carrier member 54, the torque amount of the chain motor 220 is constantly controlled by the torque signal from the torque amount setting unit 310, and the chain motor 220 is controlled. Regarding the rotation speed (chain speed) of 220, the pulse oscillator 3
04, controlled by the speed signal from the pulse train converter 306 to a speed slightly higher than the line speed. Further, when the cloth W is detached from the carrier member 54, if the torque amount is constant, the chain motor 220 rotates at a high speed. Therefore, the rotation speed (chain speed) reaches a threshold speed (hereinafter, maximum chain speed). It is controlled so that the rotation speed does not rise above a certain level. Therefore, the chain speed is slightly higher than the line speed until the cloth W is removed, and after the cloth W is removed, the line speed and the chain speed are controlled independently.

By this torque control, the tension of the cloth W between the guide rollers is always constant even if the line speed changes, and the cloth W is slackened, unnecessary tension acts on the cloth W, or the cloth W moves. Does not come off from the carrier member 54. Further, when the line speed changes, the chain speed changes accordingly, and the cloth W is smoothly conveyed. Furthermore, after removing the cloth W, the carrier member 54 moves at the maximum chain speed, and it is safe not to exceed the maximum speed.

After removing the cloth W, the chain speed may be simply controlled without torque control.

Unless the carrier member 54 is securely stopped at the point C where the cloth W is gripped, the coupler 12
6 and 128 cannot be connected to the docking members 106 and 108, respectively. Therefore, the control unit 194 controls the chain motor 220 to reduce the maximum chain speed to a chain speed of about 2 to 3 m / min (hereinafter referred to as the docking chain speed) when approaching the point C. This ensures that the carrier member 54 stops at point C.

(11) Operation State of Drawer Device Hereinafter, the operation state of the drawer device 6 will be described based on the control section 194 (see FIGS. 16 to 18).

In step 1, the operation section 222 is operated to start the dismounting operation at the dismounting speed (the chain speed is also the same as the dismounting speed). Then, pin tenter 4
Since the cloth W is conveyed by, the process proceeds to step 2. The chain speed is also controlled to be slightly higher than the cloth removal speed.

In step 2, whether or not the cloth W is detected is detected by the signal from the cloth detection sensor 196 on the left side. If the cloth W is detected, the process proceeds to step 3; otherwise, the state of step 2 is detected. Continue.

In step 3, the left chuck 86
And close to step 4.

In step 4, it is judged whether or not the cloth W is gripped. If the cloth W is gripped, the processing proceeds to step 5, and if not, the processing returns to step 3.

In step 5, the chuck 86 is rotated upward by the rotary actuator 82, and the process proceeds to step 6.

In step 6, it is detected from the signal of the chuck rotation sensor 204 whether or not the chuck 86 is rotated. If it is rotating, the process proceeds to step 7, otherwise the process returns to step 5.

In step 7, the coupler 126 is removed to invalidate the rail width change command and encoder input. Then, the process proceeds to step 8.

The chuck 88 on the right side also makes the same judgments from step 2 to step 7 and proceeds to step 8. The reason for controlling the left and right independently is because it is assumed that the web W is not stretched symmetrically on the pin tenor 4.

In step 8, the couplers 126 and 12
Remove 8 and if they are off, go to step 9
Otherwise, return to step 7.

In step 9, the chain motor 22
Drive 0. Then, the process proceeds to step 10.

At step 10, the carrier member 56.
Starts moving. Then, the process proceeds to step 11.

In step 11, the point A detection sensor 212 detects whether or not the carrier member 56 has passed the point A. If it has passed, the process proceeds to step 12, otherwise the process returns to step 11.

In step 12, the cloth removal sensor 21
The cloth W is removed from the pin 14 by the carrier member 8
It is detected whether or not the sheet is being conveyed together with No. 4, and if it is removed, the process proceeds to step 13, and if not, the operation of step 12 is continued.

In step 13, the cloth receiving plates 160,
162 and swing roll 50 are lowered, and the process proceeds to step 14.

At step 14, the carrier member 56.
Moves to the position of the shake-off device 8, that is, the position of the shake-off bucket 7. Then, the process proceeds to step 15.

In step 15, the chucks 86, 8
8 is opened, and the holding of the cloth W is released in step 16. Then, the process proceeds to step 17. Up to this step, the chain speed is slightly higher than the line speed, but in the subsequent steps, it is independently controlled as described above. Therefore, after removing the cloth W, the line speed is maintained at the cloth removing speed, and the chain speed becomes the maximum chain speed.

In step 17, when the mechanical valves 98, 104 have passed the position of the ridge 188, the chucks 86, 88 are closed and the process proceeds to step 18.

In step 18, the carrier member 56
B has passed the B point by the B point detection sensor 214. If the B point has passed, the process proceeds to step 19, otherwise step 18 is continued.

In step 19, the restriction on the line speed, which is the cloth removal speed, is released, and the normal speed is set by the operation section 222. This setting may be manual or automatic. Then, the process proceeds to step 20.

In step 20, the carrier member 5
Since 6 approaches the point C, the maximum chain speed of the carrier member 56 is reduced to the docking chain speed. Then, the process proceeds to step 22. The line speed is the normal speed.

At step 22, the carrier member 56.
C has passed the point C by the C point detection sensor. If the point C has passed, the process proceeds to step 23. If not, the state of step 22 is continued.

In step 23, the coupler 126 is docked, and the process proceeds to step 24. Also, the coupler 12
8 is also the same.

At step 24, the encoder input and the rail width change command are validated. Then, the process ends.

As described above, the cloth W conveyed by the pin tenter 4 can be automatically removed from the pin 14 and conveyed to the shake-off device 8, and the work efficiency can be improved.
