The present invention relates to a finishing device that can be manufactured .

[0002]

In Conventional Finish apparatus of this kind, for example as shown in FIG. 3, respectively in the direction of travel (direction of arrow 1) on both sides a plurality of pins 2,2, formed by arrayed ... the endlessly conveyors The mechanism 3 is driven to rotate by the motor 4, and both sides of the belt-shaped cloth 5 continuously supplied to the conveyor mechanism 3 are inserted into the pins 2, 2,... Transported to Then, the cloth 5 is subjected to heat treatment when passing through the inside of the heating device 6, and is taken up by a delivery roller 8 of a delivery mechanism 7 provided at a position downstream of the conveyor mechanism 3 while being separated therefrom. It is sequentially removed from the pin 2. Fabric fed from the delivery mechanism 7 5, further in
Way is allowed to travel along the circumferential surface of the jacket roller 9 cold却用, the fabric form is immobilized by receiving cooling action while being allowed to change its direction of travel. The cloth 5 in which the cloth form is fixed as described above is taken off by a take-off mechanism (not shown) provided on the downstream side of the jacket roller 9 and is shaken down into a storage container (not shown). It is. In this case, the delivery roller 8 and the jacket roller 9 are driven to rotate by the motor 4 which is a drive source of the conveyor mechanism 3, and are controlled at a predetermined ratio manually set by an operator. In the finishing device as described above, for example, when the sending speed of the sending roller 8 is faster than the carrying speed of the conveyor mechanism 3, the finishing device is disposed between the guide roller 10 constituting the sending mechanism 7 and the conveyor mechanism 3. The portion of the cloth 5 is overstretched, and the position of the cloth 5 on the conveyor mechanism 3 with respect to the pin 2 is retracted to the upstream side in the transport direction. On the other hand, when the delivery speed of the delivery roller 8 is low, the portion of the cloth 5 between the guide roller 10 and the conveyor mechanism 3 becomes too loose, and the cloth 5
The pin 2 may be caught and damaged by the pin 2. In order to avoid the occurrence of such an undesired state, the finisher, for example, includes a dancer roller 11 between the delivery roller 8 and the guide roller 10.

[0003]

However, in order to fix the cloth 5 in a uniform and good cloth form in the finishing apparatus as described above, the cloth 5 is almost completely removed from the peripheral surface of the jacket roller 9. It is necessary to provide guidance in order to keep you stable under tension. Therefore, conventionally, the traveling speed of the cloth 5 is manually adjusted by an operator. However, such control by the operator imposes a considerable burden on the operator, and the cloth 5 cannot be fixed to a substantially uniform and good cloth form. The present invention has been made under such a background, and its object is to perform a heat treatment without any trouble of an operator.
Always cooled in the state of Ryakuna tension, stable finish has been cloth
The purpose of the present invention is to provide a finishing device having a function that can be performed.

[0004]

In order to achieve the above-mentioned object, the main means adopted by the present invention is to summarize the heat treatment of the cloth conveyed after being heated.
While running along the peripheral surface of the cooling roller and cooling
In order to fix the fabric form, it is located downstream of the cooling roller.
With the pulling mechanism installed, the cloth is pulled with almost no tension.
In the finishing apparatus to take, it is deployed in a position spaced from the peripheral surface of the cooling roller, the distance to the surface of the fabric representing the tension degree of the cloth running along the peripheral surface of the cooling roller Detecting means for continuously detecting in a non-contact manner; and continuously moving the transport mechanism such that a distance from the detecting means continuously detected by the detecting means to the surface of the cloth becomes a predetermined value. A finishing device comprising: a control means for performing dynamic control.

[0005]

In the finishing device according to the above construction, the distance to the surface of the cloth, which indicates the degree of tension of the cloth traveling along the peripheral surface of the cooling roller, is continuously detected by the detecting means in a non-contact manner.
The take-off mechanism (transport mechanism) provided, for example, on the downstream side of the cooling roller is continuously controlled so that the detected value becomes a predetermined value set in advance. Accordingly, the cloth can be guided while being stably moved with almost no tension on the peripheral surface of the cooling roller.

Embodiments of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention. still,
The following examples are embodied examples of the present invention and do not limit the technical scope of the present invention. Here, FIG. 1 is a schematic structural diagram of engagement Ru Finish apparatus to an embodiment of the present invention, FIG 2 is a block diagram showing a control manner in the finishing apparatus. In Finish device engaging Ru in this embodiment, as shown in FIG. 1, in the direction of travel (direction of arrow 1) on both sides, a plurality of pins 12, 12, conveyor mechanisms 13 formed by arrayed ... the endlessly heating The conveyor mechanism 13 is arranged so as to penetrate through the device 14 and is driven to rotate by a motor 15. The conveyor mechanism 13 inserts both sides of the belt-like cloth 5 continuously supplied to the conveyor mechanism 13 into the pins 12, 12,. 14 for heat treatment. A delivery mechanism 18 including a guide roller 16, a delivery roller 17, and the like is disposed downstream of the conveyor mechanism 13. The delivery mechanism 18 has a function of sequentially removing the heated cloth 5 from the pins 12 while pulling the fabric 5. The delivery roller 17 is a driving source different from the conveyor mechanism 13. The motor 19 is driven to rotate. An ultrasonic sensor 20 for distance measurement, for example, is provided between the conveyor mechanism 13 and the sending mechanism 18. The ultrasonic sensor 20 detects the distance to the surface of the cloth 5 in a non-contact manner, and detects the distance from the guide roller 16 to the conveyor mechanism 13.
This is for detecting a linear distance from the upper cloth 5 to a position where the upper cloth 5 is removed from the pin 12.

The pin 1 of the cloth 5 is moved from the guide roller 16 detected by the ultrasonic sensor 20.
The delivery roller 17 or the conveyor mechanism 13 is controlled such that the distance to the pull-out position with respect to 2 becomes a predetermined value set in advance. The predetermined value in this case corresponds to a linear distance from the guide roller 16 at a position where the cloth 5 can be stably pulled out from the pin 12 on the conveyor mechanism 13 with almost no tension. In defining the above-mentioned predetermined value, the distance from the position where the cloth 5 is removed from the pin 12 to the end of the heating device 14 on the outlet side may be defined. Downstream of the delivery mechanism 18, a cooling jacket roller 21 for cooling the heat-treated cloth 5 and fixing the form of the cloth while guiding the cloth 5 is fixedly provided . Outgoing roller 1
The cloth 5 sent from the jacket roller 21 is
Caused some shrinkage by cooling
The cloth 5 passes through the jacket roller 21 under tension.
Then, unnecessary distortion occurs in the cloth 5 and stable quality.
Can not get. On the other hand, the cloth 5
If it is away from the roller 21, a sufficient cooling effect cannot be obtained. So
Here, sufficient cooling effect can be obtained and stable quality
In order to obtain the distance between the cloth 5 and the jacket roller 21,
It needs to be kept almost constant. Note that the jacket roller 21 is driven to rotate with a suitable transmission ratio by the motor 19 for driving the feed roller 17. The cloth 5 running along the peripheral surface of the jacket roller 21
Is taken up by a take-up roller 23 constituting a take-up mechanism 22 disposed downstream of the jacket roller 21 and is shaken down into a container 24. In this case, the take-off roller 23 is driven to rotate by a dedicated motor 25.

[0008] position or during circumference et away of the jacket roller 21, for example, for distance detection is generally continuous use
An ultrasonic sensor 26 (detection means) is provided. The ultrasonic sensor 26 detects the degree of tension of the cloth 5 traveling along the peripheral surface of the jacket roller 21 .
This is for detecting the distance to the surface continuously without contact. As a continuously <br/> detected predetermined value L ₂ the distance from the ultrasonic sensor 26 to the surface of the fabric 5 is set in advance as by the ultrasonic sensor 26, the take-up The roller 23 is continuously controlled (control means). In this case, the predetermined value L ₂ described above corresponds to the distance to the surface of said fabric 5 upon which the fabric 5 is in contact substantially and homogeneous state of no tension on the circumferential surface of the jacket roller 21. A guide device is constituted by the jacket roller 21, the ultrasonic sensor 26, a controller 27 (see FIG. 2) described later, and the like. The finishing device according to the present embodiment is configured as described above. Fig. 1
A control mode in the finishing device will be described with reference to FIG. In this case, the ultrasonic sensor 20,
The values corresponding to the predetermined distances L ₁ and L ₂ in 26 are manually set by the operator.
Distance L _1, L ₂ the predetermined is as described above, the distance from the pin 12 on the conveyor mechanism 13 to the surface of said fabric 5 upon which the fabric 5 can be stably vent away almost the unstretched state, This corresponds to the distance to the surface of the cloth 5 when the cloth 5 contacts the peripheral surface of the jacket roller 21 without tension and uniformly.
Further, the transport speed in the conveyor mechanism 13 serving as a reference is also set. Under the above-described premise, the strip-shaped cloth 5 continuously supplied to the conveyor mechanism 13 is inserted into the pins 12, 12,... , And a heating device 14.

The heated cloth 5 is picked up by the delivery roller 17. In this case, first, the position of the cloth 5 on the conveyor mechanism 13 coming out of the pins 12 is almost tensionless for the cloth 5. to correspond to a site which can be a state, i.e. such that the distance from the ultrasonic sensor 20 to the surface of the fabric 5 is substantially equal to L _1, the feed roller 1
7 is manually set by the operator. When the operation shifts to the automatic operation, the controller 27
From the control signal corresponding to the deviation between the distance and the distance L ₁ to the surface of the fabric 5 from the ultrasonic sensor 20 upon the manual set is output. This deviation signal is added to the control signal for the motor 19 for driving the feed roller 17 during the manual setting as a reference, so that the distance between the ultrasonic sensor 20 and the cloth 5 of the front surface is the value of L ₁ The motor 19 is controlled at the same time. That is, since the feedback control is performed based on the rotation speed of the motor 19 in the actual running state of the cloth 5, the take-up state of the cloth 5 does not greatly change, and the target distance L ₁ can be extremely smoothly adjusted. The operation is controlled as follows. In the control according to the above procedure, even when the deviation between the set value at the time of manual setting and the target value is large, the control state is brought close to the target value without greatly affecting the cloth 5. Can be. The cloth 5 whose running speed is feedback-controlled as described above is stably pulled out from the pin 12 on the conveyor mechanism 13 with almost no tension, and a uniform and good state can be obtained. The cloth 5 that has been subjected to the heat treatment and sent out from the sending mechanism 18 is guided along the peripheral surface of the jacket roller 21 while being taken by the taking roller 23 of the taking mechanism 22 in order to fix the form of the cloth. To run.

In this case, the motor 25 of the take-off roller 23 with respect to the state of the cloth 5 on the jacket roller 21
Is almost the same as in the case described above. That is, the rotation speed of the motor 25 is manually set by the operator so that the cloth 5 follows the peripheral surface of the jacket roller 21 in an almost ideal state. Control signal corresponding from the ultrasonic sensor 26 when the guide is set to the deviation between the distance and the distance L ₂ to the surface of the fabric 5 is continuously outputted from the controller 27 during the automatic operation. Then, the deviation signal is added to the control signal for the motor 25 at the time of the manual setting, and the feedback control is continuously performed so as to be in an ideal control state under an extremely smooth speed fluctuation. Therefore, the cloth 5 is always guided with almost no tension and stably along the peripheral surface of the jacket roller 21, and is fixed in a uniform and good cloth form. The cloth 5 whose cloth form is fixed as described above is shaken down into the container 24. The ultrasonic sensor 2 in the above embodiment
The technology may be applied to a case where an optical sensor is used instead of 0 and 26 and a clip tenter is used instead of the pin tenter. Furthermore, even if this technology is used for a conveyor mechanism having no pins or clips in each of the above tenters, the cloth can be stably pulled off in a substantially tensionless state, which is suitable for a wide range of cloth finishing processes. Further, in the above embodiment, the case where the take-off mechanism 22 is controlled based on the output from the ultrasonic sensor 26 has been described as an example. However, the same effect can be obtained by controlling the delivery mechanism 18 instead of the take-off mechanism 22. It goes without saying that you can get
