2. Description of the Related Art The temperature of the cloth processing chamber must be raised before the tenter is operated. However, if the temperature of the cloth processing chamber is raised with the tenter stopped, the temperature of the pin in the cloth processing chamber is increased. There is a difference in thermal expansion between the chain and the non-heated pin chain outside the cloth processing chamber, which causes trouble at the start of operation. Therefore, when the temperature of the fabric processing chamber is raised prior to the operation of the tenter, the pin chain is always idled, and the guide cloth (guide cloth) cannot be passed in advance when the tenter is stopped.

Nevertheless, it is necessary to thread the cloth before the operation of the tenter. Conventionally, the threading is performed as follows. That is, the cloth is bitten by the pin chain on the inlet side of the cloth processing chamber and moved to the cloth outlet of the cloth processing chamber, and after removing the cloth from the pin chain, the shake-off roller is manually passed through a predetermined guide roller. , Through the fabric guide, leading to the carrier.

[0004]

The work of manually threading the cloth from the cloth outlet to the shake-off section of the cloth processing chamber is as follows.
You have to enter a narrow space with a guide roller, and it is difficult and dangerous to pass the cloth through a guide roller or a swing-off roller at a high place.

An object of the present invention is to provide an automatic cloth threading device for a cloth exit section of a tenter, which can automatically carry out cloth threading from a cloth exit section to a swing-off section of a cloth processing chamber without requiring human labor. I am trying.

[0006]

To achieve the above object, an automatic cloth threading device for a cloth outlet portion of a tenter according to the present invention is provided with a left and right endless chain extending between a cloth outlet portion and a swing-off portion of the tenter. A pair of holders supported by the holder, an adhesive bar held between both holders, a device for rotating the holder at the cloth outlet of the tenter, and a cloth at the cloth outlet of the tenter to contact the adhesive bar by removing the cloth from the pin chain. It is composed of a lever and a cam for releasing the holding of the adhesive bar from the holder at the swing-off portion.

[0007]

[Operation] In the automatic threading device for the cloth outlet of the tenter configured as described above, the operation of the pin chain is started, and the front end of the cloth attached to the pin chain at the inlet of the tenter is the operation of the adhesive bar. A little past the starting position, the front end of the cloth is disengaged from the pin chain by the lever, comes into contact with and sticks to the rotating adhesive bar, and is wound around the adhesive bar. Then, the front end of the cloth moves to the swing-off portion as the chain runs. At that position, the adhesive bar is released from the holder by the cam and falls. At that time, the wrapped cloth is unwound from the adhesive bar.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automatic cloth threading device for a cloth outlet of a tenter according to the present invention will be described with reference to FIGS.

The automatic cloth threading device for the cloth outlet of this tenter is a tenter for holding the cloth F between the endless pin chains 2 which run along the tenter rails 1 on the left and right, respectively, in a widthwise direction. The holder 8 for holding the adhesive bar 9 is provided at one place of the chain 3 extending from the cloth outlet portion to the swing-off portion of the cloth processing chamber provided with, and the front end of the cloth F carried by the pin chain 2 is provided at the cloth outlet portion. A structure is adopted in which the lever 12 provided on the upper part of the holder 8 is attached to the adhesive bar 9 to wind it, and the cam 16 provided on the swing-off portion releases the adhesive bar 9 from the holder 8.

The chain 3 has sprocket wheels 6A, 6B and 6C interposed between a sprocket wheel 4 provided at a cloth outlet and a sprocket wheel 5 coaxial with a swing-off roller 14 provided at a swing-off portion. It has been stretched. Sprocket wheels 5, 6
A, 6B, and 6C are swing-off rollers 14, respectively.
The sprocket wheel 4 is provided between each end of the guide rollers 7A, 7B and 7C and the roller bearing, and the sprocket wheel 4 is supported by the bearing. The chain 3 is driven in the direction of the arrow by the motor M1 after the front end of the cloth is wound around the adhesive bar 9. A pressing roller 15 is provided above the swing-off roller 14 to ensure stable running of the cloth F. A cloth guide 17 is provided below the swing-off roller 14.

As shown in FIG. 3, the holder 8 of the adhesive bar 9 is supported by a shaft of a gear 10 rotatably supported by the chain 3 via a coil spring 22 so as to be movable only in the axial direction. , Has a large-diameter boss portion 8a in the middle, and can receive the adhesive bar 9 in the concave portion at the free end. At that time, the protrusion 9 a protruding near the end of the adhesive bar 9 engages with the edge of the recess of the holder 8. Therefore, when the holder 8 rotates, the adhesive bar 9 also rotates together.

As shown in FIG. 6, the gear 10 is engaged with a reverse rotation stop spring 18 fixed to the chain 3 so that it can rotate only on one side. Therefore, it is possible to prevent the cloth F from being unwound due to the gear 10 reversing during the conveyance and the holder 8 and the adhesive bar 9 reversing.

The surface of the pressure-sensitive adhesive bar 9 is coated with a pressure-sensitive adhesive to which cloth can be attached and easily peeled off. The holder 8 of the adhesive bar 9 is at the position of the sprocket wheel 4 at the start of the operation, and as shown in FIGS. 1 and 3, at this position, the motor M2 is moved through the gears 10 and 11.
