BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for surely gripping and winding a knitting cloth when winding a knitted cloth.

[0002]

2. Description of the Related Art Conventionally, for example, as disclosed in Japanese Patent Publication No. 2-2862 of the applicant of the present application, at the beginning of winding a knitted fabric, the fabric is sandwiched and wound by a split type take-up shaft. Was doing.

[0003]

However, since the ends of the left and right winding shafts are formed in the shape of slopes, respectively, when the left and right winding shafts are pressed and pressed to drive, both winding shafts are driven. Since the binding force at the shaft end is weak, a bending moment is generated at the end of the winding shaft, and an extra load is applied to the drive of the winding shaft, which adversely affects the drive of the knitting circular knitting machine and the winding mechanism. There was a flaw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numerals 1 and 2 are split type winding shafts for cloth, which are provided in pairs on the left and right, respectively, and are appropriately provided on a pair of winding frames F, F. The convex portion 4 is formed, and the concave portion 3 is formed of the elastic body 5.
The elastic body 5 is directly fixed to the main body of the winding shaft 1 via a screw or the like.

Further, as shown in FIG. 5, the convex portion 4 of the split winding shaft 2 may be formed of the elastic body 6 in the same manner as described above to form the convex portion 4. Further, as the material of the elastic bodies 5 and 6, for example, a material having a high elasticity such as polyurethane synthetic resin or synthetic rubber is preferable.

In FIGS. 6 to 8, reference numeral 33 denotes a compressed air jet pipe properly fixed to the leg portion 34 of the circular knitting machine, and the width of the knitted fabric A with respect to the hanging knitted fabric A after cutting. Direction, the compressed fabric is blown to the left half side or right half side of the fabric to displace the fabric, and the split type winding shaft 1,
The line connecting the two and the fabric cross each other so that the knitting fabric A can be easily pressed and clamped by the split type winding shafts 1 and 2.

The operation of the winding device is known as described in, for example, Japanese Patent Publication No. 2-6862, but its outline will be described. First, the material A knitted as shown in FIG. 1 is taken up by the split type take-up shafts 1 and 2 via the feed rollers 10, 10 and 10.

In this case, regarding the split type winding shaft 1,
Regarding the split type winding shaft 2 driven via the gears 15 and 16, the chain wheel 17, the chain 18, the chain wheel 19, the rotary shaft 20, the chain wheel 23, the chain 24, the chain wheel 25, and the gears 30 and 31. And is driven in synchronization with the split-type winding shaft 1.

When the knitted fabric A is wound up by a predetermined amount and is fully wound, the winding mechanism, that is, the split winding shafts 1 and 2 are moved to predetermined positions X and X by known means, as shown in FIG. Stop and
The cloth carry-out member 36 enters the position below the winding cloth B.

Next, the take-up shaft pull-out mechanisms 38, 38 rotate 90 degrees to sandwich the split-type take-up shafts 1 and 2, respectively, and the tip end of the split-type take-up shaft 1 is moved from positions L1 to L2 as shown in FIG. In addition, the tip end of the split type winding shaft 2 is also retracted from the position K1 to K2 as shown in FIG.

Next, when the winding material B is removed from the split winding shafts 1 and 2, the winding material B is dropped onto the unloading member 36, and when the hanging knitted material A is cut, the wrapping material B is removed. It is carried out of the knitting machine via 36.

Further, when the winding material B is carried out of the knitting machine,
Compressed air is jetted onto the knitted fabric A after cutting.
That is, as shown in FIGS. 6 and 7, compressed air is jetted to the hanging knitted fabric A through the compressed air jet pipe 33, and the fabric on the left half of the knitted fabric A in FIG. 7 is displaced, The divided winding shafts 1 and 2 project laterally from the line connecting the divided winding shafts 1 and 2, and in this state, the divided winding shafts 1 and 2 move from their original positions L2 to L, respectively.
1, when returning from the position K2 to the position K1, the hanging knitted fabric A is crimped via the divided winding shafts 1 and 2, as shown in FIG.
It is pinched. Then, when the circular knitting machine is driven again, the split winding shafts 1 and 2 that crimp and sandwich the knitting fabric A respectively rotate to wind up the knitting fabric A.

[0014]

As described above, the present invention is a split type in which the knitting fabric A knitted by the knitting means is wound while being rotated on the pair of left and right winding frames that rotate and stop in synchronization with the knitting means as described above. In the fabric winding device of the knitting circular knitting machine supporting the winding shafts 1 and 2, the split type winding shafts 1 and 2 have their tip portions formed in an uneven shape, and either of the tip portions of the coaxial shafts 1 and 2 is formed. By configuring one or both with elastic body,
Since the connecting force between the ends of the split type winding shafts 1 and 2 is strengthened and an extra load is not applied to the drive of the winding shaft unlike the conventional case, the drive of the knitting circular knitting machine and the drive of the winding mechanism. Is carried out smoothly, and a knitted fabric of good quality can be obtained. In addition, the compressed air injection pipe 3 provided on the leg of the circular knitting machine
By squeezing compressed air to the part on the half side in the width direction of the knitted fabric through 3 to displace the part of the fabric, the split type winding shafts 1 and 2 can easily press and sandwich the fabric. It is possible to reliably wind up the dough.
