Description

  The present invention relates to a take-up device for a fabric with rubber used when producing a fabric with rubber used as a tire material.

  In the manufacture of tires, various sizes of tape-like fiber cord bands (jointless bands: hereinafter also referred to as “JLB”) are used, and these JLBs are generally produced with a width of about 1500 mm. After winding the woven fabric with rubber and making it the top counter, this top counter is set in a winding device and slit to a width of about 80 to 100 mm to make a JLB parent material (cameron slitter process), JLB It is manufactured through a splitting process (JLB slitter process) for slitting the parent material to a width of about 10 mm (Patent Document 1).

  FIG. 3 is a perspective view schematically showing a main part of a conventional JLB parent material winding device. As shown in FIG. 3, the winding device 1 includes a rotating shaft 2 and a plurality of winding boxes 3. I have. Then, the winding box 3 is engaged with the rotating shaft 2 by the fitting hole (square hole) 3b and rotates together with the rotating shaft 2, so that the JLB parent material roughly divided from the unrolled top is taken up.

  However, the above-mentioned JLB parent material is taken up from the rotating shaft of the take-up box, and the take-up box is mounted on the JLB slitter by hand, considering the weight that can be lifted by the operator. Then, it has been difficult to increase the winding length and improve productivity. For example, with a JLB base material having a width of 80 mm, the winding length remains at about 300 m (weight 20 kg), and the productivity cannot be sufficiently improved.

  In addition, in the slitting process for slitting the JLB parent material, as shown in FIG. 4, each time the JLB parent material is unwound from the winding box 3 attached to the JLB slitter and the slit ends, a new winding box and Since it is necessary to change (manually change) manually, it takes a long time to change, and the productivity cannot be improved sufficiently.

  Therefore, the present invention provides a JLB parent material with a sufficiently extended winding length in the large splitting process, and shortens the changeover time in the split splitting process, so that the productivity can be sufficiently improved. It is an object of the present invention to provide a winding device for a fabric.

Advantages of Embodiment (1) In this embodiment, the hoist is used to remove the take-up box together with the rotating shaft from the take-up device and attach it to the JLB slitter unwind device. The work of carrying and mounting can be carried out without human intervention. For this reason, in a large-scale process, the restriction | limiting of a weight is eased and the winding length of a JLB parent material can be lengthened, and the frequency | count of replacement | exchange of a JLB parent material is reduced. In addition, the number of JLB joints is reduced.

(2) In the present embodiment, the winding box and the rotating shaft are integrated, and the winding box can be replaced only by sliding the rotating shaft in the splitting process. Changeover time is shortened and productivity is improved.

(3) Moreover, the width | variety of the winding box is enlarged only 20-80 mm compared with the width | variety of the textile fabric with rubber | gum to wind. For this reason, while preventing protrusion of the rubber-woven fabric from the winding box due to being less than 20 mm, it is possible to prevent deterioration of productivity due to exceeding 80 mm.

(4) Further, since the connection key is attracted to the rotating shaft by magnetic force, troubles due to the connection key falling off and being unlocked during winding are prevented.

  Hereinafter, based on an Example, this invention is demonstrated more concretely.

In this example, after the top counter having a width of 1440 mm and a length of 600 m was slit to 80 mm in a rough process, 18 JLB base materials were produced, and then this JLB base material was described in the above embodiment. Each winding box was wound up by 600 m using a winding device in which the winding box and the rotating shaft were integrated.

  Next, the JLB parent material wound around the winding box was transported to the splitting process using a hoist together with the rotating shaft, slit into a width of 10 mm, and eight JLBs were produced for each winding box. The change of the JLB parent material was performed by sliding the rotating shaft around which the JLB parent material was wound.

(Comparative example)
A JLB parent material slit in the same size as the embodiment in the same process as in the embodiment, using a conventional take-up device in which the take-up box and the rotating shaft are different types. It was.

  Next, the JLB parent material wound up in the winding box was manually transported to the splitting process and slit into a width of 10 mm to produce a JLB. When changing the JLB parent material, each time the unwinding of the JLB parent material of each box is completed, the used winding box is manually removed from the rotating shaft, and the winding box where the JLB parent material is wound is removed. Set by human power.

2. Evaluation of productivity The productivity in the examples was evaluated with the productivity in the comparative example as 100. Specifically, it evaluated by comparing the JLB production length (winding length) per hour in an Example and a comparative example. As a result, the productivity of the example was evaluated as 115, and it was confirmed that the productivity was improved by 15% by applying the example.
