Description

  The present invention relates to a tension adjustment architecture for a fabric winder, and more particularly, to a tension adjustment architecture capable of controlling the winding tension when a high-leg high-speed cloth winder starts winding the fabric.

  Conventionally, cloth knitted by a knitting machine has been wound and stored by a cloth winder (for example, Patent Document 1). The cloth winder disclosed in Patent Document 1 has two side boxes. Two guide rails extending obliquely are provided in the middle part of the two side boxes, and both ends of the winding rod can be respectively arranged. Below the two guide rails, a first cloth feed shaft and a second cloth feed shaft extending in parallel with each other are provided horizontally. The cloth winder feeds the cloth with the first cloth feed shaft and the second cloth feed shaft, and winds the cloth with the take-up rod. In this cloth winding process, as the cloth on the winding rod increases, the cloth is moved upward along the guide rail by the winding rod. For the use of the cloth winding machine, the following (1) to (3 ).

(1) The first cloth feed shaft rod and the second cloth feed shaft rod are pressed by the cloth wound up by the take-up rod and become heavier as the cloth taken up by the take-up rod increases. Since the downward pressure of the cloth feed shaft and the second cloth feed shaft becomes large, there is a possibility that the winding tension of the cloth gradually increases and becomes non-uniform.
(2) Since the take-up rod is only fitted in the guide rail, it is easy to come off, and there is a possibility that the take-up rod may jump out of the cloth winder during the cloth winding process.
(3) Since the capacity of the cloth is as small as about 20 kg, it is inconvenient to dye, and there is a possibility that waste materials increase.

  Patent Document 2 and Patent Document 3 disclose a cloth winding machine that includes two side boxes, a cloth winding device and a cloth feeding device provided between the two side boxes, a cloth winding device and a cloth via a belt and a pulley. And a driving device for driving the feeding device. The cloth feeding device includes a support arm and a cloth rolling bar provided on the support arm. When the cloth winding process is performed, as the amount of the cloth wound on the winding rod of the cloth winding device increases, the wound cloth becomes thicker, hitting the cloth rolling rod, causing friction, and the winding rod rotates. Store the cloth. As described above, when the cloth winding process is performed, the cloth is pressed by the cloth rolling rod, so that there is a possibility that the tension increases with the winding of the cloth. That is, Patent Document 2 and Patent Document 3 have the following disadvantages (1) and (2).

(1) When starting to take up the cloth, since the cloth is taken up with a large tension by the take-up rod, the tension of the belt and pulley of the take-up rod is high. Therefore, the take-up rod can take up the cloth with a large take-up force, but the belt and the pulley are driven with high tension for a long time, so that the belt is worn and the service life may be shortened. Therefore, the belt has to be frequently changed, and the cost and time for maintenance increase, which is not economical.
(2) Since the belt is worn for a long time with high tension, the belt is worn, the frictional force between the belt and the pulley is lowered and slippery, and the winding force when the winding rod starts to wind is reduced. There was a risk of shortage. Therefore, when the cloth winder rotates at a high speed, the cloth on the winding rod loosens, and when the cloth is wound up and gradually thickens, the cloth is shifted to one side of the winding rod with the rotation and the balance is balanced. Sometimes it could not be maintained. Thus, when an abnormality occurs in the winding of the cloth, there is a possibility that the operation of the apparatus must be stopped.

The auxiliary wheel 74 is used to pull the pressure contact member 80 by changing the direction by the tow string 73.

  Reference is made to FIG. 4A. As shown in FIG. 4A, when the cloth winder of this embodiment is used, the cloth 90 is guided to the winding rod 30 by the main roller bar 51 and the sub roller bars 52 and 53 of the cloth feed mechanism 50. The cloth presser bar 42 at the start of winding the cloth is in the first position not in contact with the cloth 90. As shown in FIG. 5A, when the presser bar 42 reaches the first position, the operating member 41 presses the braking member 60 to press the operating end 61, and the mounting portion 62 is raised. Refer to FIG. 6A. As shown in FIG. 6A, when the movable rod 81 and the elastic member 83 are pulled by the connection block 71 and the traction string 73 of the connection unit 70, the pressing wheel 82 is applied to the belt 103, and is stretched around the pulleys 101 and 102. It is possible to prevent the belt 103 being slipped from slipping. Therefore, the tension at the time of winding the cloth can be improved by increasing the number of rotations of the winding rod 30, and the cloth 90 can be stably wound around the winding rod 30.

  Refer to FIG. 4B. As shown in FIG. 4B, when the cloth 90 wound up by the winding rod 30 reaches a certain amount as the operation time elapses, the cloth presser bar 42 in contact with the cloth 90 reaches the second position. Go up. When the operating arm 41 is raised, the working end 61 is raised and the mounting portion 62 is lowered. Next, refer to FIG. 6B. As shown in FIG. 6B, the movable rod 81 is loosened by the connection block 71 and the traction string 73 of the connection unit 70, the elasticity of the elastic member 83 pulls back the movable rod 81, and the pressing wheel 82 is separated from the belt 103. As a result, the take-up rod 30 and the presser bar 42 have different rotation speeds, and even if the belt 103 of the take-up rod 30 slides on the pulleys 101 and 102, the take-up of the cloth 90 is controlled by the presser bar 42. Therefore, the tension of the cloth 90 can be made uniform.

  As can be seen from the above, the tension adjustment architecture of the fabric winder of the present embodiment is such that when the fabric starts to be wound via the braking member 60 of the adjustment mechanism, the operating arm 41 is pressed to the first position, By pulling the connection unit 70 and applying the pressure contact member 80 to the belt 103 of the first transmission unit 100, the winding force when the winding rod 30 starts to be wound can be improved. As described above, when winding is started by the cloth winder, the cloth 90 can be stably wound by the winding rod 30, and the cloth 90 can be prevented from being displaced and wound on the winding rod 30. Further, in the winding process, when the winding amount of the cloth 90 reaches a predetermined amount, the operating arm 41 is moved up to the second position by the cloth 90. The braking member 60 drives the connection unit 70 by pressing the operating arm 41, and the pressure contact member 80 is separated from the belt 103. Therefore, the wear life of the belt can be reduced and the service life can be extended. When the pressure contact member 80 is separated from the belt 103, the take-up rod 30 is also released at the same time. Therefore, the cloth 90 controlled by the cloth presser bar 42 is adjusted by the take-up rod 30, and the take-up tension of the cloth 90 is made uniform. Can do.

  Although preferred embodiments of the present invention have been disclosed above, as will be appreciated by those skilled in the art, they are not intended to limit the invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the claims of the present invention should be construed broadly including such changes and modifications.
