Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a jointing machine that automatically balances the weft threads of fabric by applying tension to them.

``Prior Art'' Conventionally, in order to correct the unbalance of the weft threads of a woven fabric and to align the joints, both ends of the woven fabric were held by hand and stretched or stretched using a spiral member. However, this manual enlarging process has the drawback of poor working efficiency and the inability to achieve uniform enlarging.

``Problems to be Solved by the Invention'' The present invention aims to provide a joint adjustment machine that mechanically performs joint alignment accurately and uniformly, eliminating the need for rework, whereas conventional joint alignment was performed manually.

``Means for Solving the Problems'' The present invention provides a guide roller having the same overall length and the same diameter in the center, and has both sides of the guide roller in the same axial direction, and the diameter increases from the center and the guide roller side toward the outside. A tapered roller for tensioning the weft thread and a tapered roller for the cloth foil are respectively rotatably mounted on shafts, and the movable roller is brought into contact with a pulling roller that pulls the wound cloth foil around the guide roller and the tapered roller. It is configured to be spaced apart.

``Function'' The present invention is configured as described above, and the present invention is configured as follows. After the weft threads have been adjusted, the wrinkles in the fabric have been stretched out, and the seams have been aligned, the fabric is transferred to the net machine.

"Central Example" An example of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway front view, FIG. 2 is a side view, FIG. 3 is a plan view of one of the tapered rollers, and FIG. 4 is a side view of the roller in combination with the a-motor. 1 is frame, 2 is frame 1
Guide rollers with the same diameter and full length are mounted on bearings 3 provided on both sides of the upper center of the guide roller. 4 and 5 are tapered rollers for weft thread tensioning, which are axially aligned almost in the same direction as the guide roller 2 and whose diameters increase toward the outside when viewed from the guide roller 2 side at the center, and both ends are supported by bearings 6. and 7, respectively. 8%7L/-A□. A cloth foil roll is mounted on a front lC5 bearing 9, and the width of the cloth foil roll is wider than the width of the guide roller 2, so that it covers a part of the rollers 4 and 5. Become a b.

Reference numeral 10 denotes a retracting roller horizontally suspended on the frame 1 with the same axial direction as the guide roller 2 below the guide roller 2 and the tapered roller 4°5, and 11 a retractable movable retracting roller 10tC configured to contact or separate from each other. It's Laura. One end of the retractable movable roller 11 is fixed to the 7-frame 1, and the other end of the L-shaped bar 12 is connected to a roller opening/closing device 13 using a link mechanism.

By manually operating the opening/closing device 3, the movable retractable rowia 11 is made into an L shape, swings about the shaft stop of the bar 12 as a fulcrum, compresses the spring 14, and separates the movable retractable roller 1lt from the retractable roller 10. Insert the cloth foil 8 between the retraction roller 10 and the retraction movable roller 11, and
When the lever 13a is released, the restoring force of the spring 14 pinches the movable retracting roller 1lt and the cloth foil 8 and presses it against the retracting roller IO. A tin rocket 15 is fixed to the shaft of the pull-in roller 1O, and a check 718 is suspended between the sprocket 15 and a tin rocket 17 having a 16-shaft motor mounted on 7 frames 14C. One end of the wrapped cloth foil 8 is pulled out and wrapped around the guide roller 2, tapered rows 74 and 5, and then placed between the pull-in roller 0 and the illuminating movable roller 11, and the motor 16 is driven to remove the sprocket) 15 , 17, when the draw-in row 710 is rotated clockwise in FIG.

and 5 so that the first drawer is pulled out, and the first handle 13at-second
Turn the cloth in the direction opposite to the direction of the arrow in the figure, and the elastic force of the spring 140 pulls the cloth through the movable roller 11. , since the both side edges of the cloth <8 are suspended from the tapered rollers 4 and 5, the both side edges of the cloth foil suspended from the tapered rollers 4 and 5 are on the outside of the tapered rows 94 and 5. Because they have a large diameter, they act as if they are stretched outward from each other. Therefore, the sagging, wrinkles, etc. of the cloth are eliminated, and the weft threads are kept aligned with the drawing roller 1.
0 and the retractable movable roller li, and is reeled out.

The cloth foil 8 that has passed between the retraction roller IO and the retraction movable rownier 11 is sent to the net machine A as shown in FIG. The net machine A has a lower frame 20 and a right triangular upper body frame 21, and a first steam injection box 22 and a second steam injection box 23 are provided on the oblique side 21& of the upper body frame 21. A roller 25 is provided below the first steam injection box 22 and is moved up and down by an initial roller push-up device e24. Reference numeral 26 is a net main belt which is suspended from reeds, rollers 27, 28, 29, 30 and a sagging tin rocket 31. A belt 34 is suspended between a drive roller 32 coaxial with the roller 30 and a main motor 33, and by driving and rotating the main motor 33, the main belt 26 rotates in the direction of the arrow in FIG. In the drawing, the cloth foil 8 that has passed between the roller 10 and the movable drawing roller 11 is moved in the direction of the lower roller 27, passes under the roller 25, and is placed on the net main belt 26.
At the same time, the steam injected from the first steam injection box 22 and the second steam injection box 23 causes the weft to straighten and knit the fabric. 34 is a steam outflow box installed above the oblique side 21JL of the upper body frame 21 in order to guide the injected steam from the first and second steam injection boxes 22 and 23 to the outside. It is sucked and discharged by rotating 77 inches. The cloth 8 that has passed through the row: ) 28 is connected to the upright side 2-1 b of the upper body frame 21.

6 has a built-in heater 38 to cool it, and then the cloth foil 8 is cooled by outside air sucked through the cloth foil 8 by a blower motor 39.

Reference numeral 40 denotes a fabric stacking table which is reciprocated in the left and right directions in the lower frame 20 in the left and right directions in FIG.
8 are folded into an S shape and stacked.

"Effect" The present invention is constructed as described above, so that the unbalance of the insect-repellent weft yarn or the wrinkles of the cloth sheet when weaving a long cloth sheet or winding up the winding roll can be avoided by the guide. The joints can be aligned by being corrected and tensioned by the roller and the tapered rows 9 arranged in the axial direction on both sides thereof. In addition, the cloth sheet pulled out from the winding roll is aligned by a guide roller and a taper roller, and the weft threads are aligned by a pull-in roller and a retractable movable roller. This has the advantage of being able to perform tasks automatically and at high speed.
