Description

[Detailed Description of the Invention] In the production of woven or knitted fabrics, the raw fabric is folded in a zigzag pattern and placed in a container or rolled up on a roller, but in recent years the method of rolling it up on a roller has become common. Especially in circular knitting machines, a winding roller is installed at the bottom of the machine and rotates to wind up the fabric and apply appropriate tension to the fabric, but due to recent labor conditions. To save labor, the fabric is automatically cut when the winding roller is full, the full fabric is discharged outside the machine, and a new winding roller is automatically supplied to the machine. A device has been developed in which the tip of the fabric is grasped and rolled up while it is being made. In this case, as a means for grasping the fabric, there is a device in which needles are planted (fixed) on the roller, but it is difficult to remove the fabric from the roller of this type because the needles become an obstacle.

This invention allows the needle to protrude from the surface of the roller when winding up the fabric in order to make it easier to wind up the roller and to easily remove the fabric. It was designed to do so.

One of the examples is explained with reference to the drawings.
1 is a hollow cylinder forming the surface of the roller, and collars 2 and 3 are fitted to both ends of the hollow cylinder. color 2,3
A pair of tongues 4, 4, 5, and 5 each having a half-moon cross section protrudes from inside thereof, and the portions between the tongues 4 and 4 and between 5 and 5 serve as holding portions for the operating rod 6. A shaft 7 is loosely fitted into the collar 2, and a driving gear 8 is fixed to the outer end of the shaft 7 with a bolt 10 through a key 9. 11 is a bearing. A prismatic portion 12 is formed at the inner end of the shaft 7, which fits into the end-shaped portion 13 of the operating rod 6, and the operating rod 6 and the shaft 7 are integrally connected by screws 14,14. The collar 2 has a hollow cylinder 1 and a tongue piece 4 fixed to each other by a screw 15. Collar 3 connects bolt 16 with hole to hollow cylinder 1
The tongue pieces 5 and 5 are fixed together by screwing with a socket bolt 18 through a long hole 17 in the operating rod 6. A shaft 19 is provided at the outer end of the collar 3.

The shafts 7 and 19 are mounted on a cloth making machine and used for winding up the cloth. One end of the operating rod 6 is fixed to the inner end of the shaft 7, and the operating rod 6 has a pair of inclined guide holes 20 that gradually become lower from right to left, and a pair of inclined guide holes 21 that gradually become lower from left to right. A pair of needle support rods 22 and 23 are provided on both sides of the operating rod 6, to which pins 24 and 25 are respectively fixed.
24 into the inclined guide holes 20 and 21. The needles 26 and 27 planted in the needle support rods 22 and 23 are placed in holes 28 and 29 made in the hollow cylinder 1, and as the shaft 7 is moved from side to side in FIG. 26 and 27 are starting to appear.

The winding roller, which has been taken out from the machine after winding up a certain amount of cloth, moves in the direction of pushing the shaft 7 into the hollow cylinder 1 and the collar 2 (leftward in Figure 1), and then the winding roller is fixed to the shaft 7. The operating rod 6 has tongue pieces 4, 4,
5, 5 and move in the same direction, during which time the needle support rods 22, 23 are guided by the steps 30, 3 provided on the tongues 5, 5.
Since the pins 24 and 25 installed in the needle support rods 22 and 23 are prevented from moving by move in the direction. At this time, since the needle 12 does not protrude from the surface of the hollow cylinder 1 and is smooth, the take-up roller can be easily pulled out from between the cloth materials.

Before the winding roller is installed in the machine, the shaft 7 is pulled in the pulling direction (rightward in Figure 1), and the operating rod 6
The needle support rods 22, 23 are moved in the centrifugal direction via the pins 24, 25 by the inclined guide holes 20, 21,
Needles 26 and 27 are made to protrude from the hollow cylinder 1.

As explained in detail above, the device of the present invention can protrude outside the needle roller by pulling the end shaft of the roller, and retract the needle into the roller by pushing the shaft, and is capable of automatically winding up woven fabrics, etc. When removing the fabric from the rolled up roller, the fabric can be smoothly removed without the needle getting in the way.
