Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a first and a second bobbins in which cords, which are core bodies of belts, are coaxially arranged in parallel at predetermined intervals. The present invention relates to an automatic winding device that winds continuously.

(Prior Art) There is known a dip processing device that performs a dip processing in which an adhesive is attached to a surface of a cord as a core body of the belt in order to improve adhesion.

In such a dip processing device, in order to improve the winding efficiency, it is conceivable to continuously dip two cheeses having untreated cords wound thereon.

Such a device is, for example, as shown in FIG.
The tip b ₂ of the second cheese b is connected to the pictail a ₁ of the second cheese a, and the joint portion c thereof is locked to the Shoint detector d, and the first cheese a is wound up. When the second cheese b is rolled up, the joint detector d detects the passage of the joint part c and outputs a detection signal to the controller e. Therefore, the controller e outputs a bobbin switching signal to the winder,
It is conceivable that the bobbins to be wound can be switched automatically.

(Problems to be Solved by the Invention) However, in this case, when the first bobbin g on which the cord f is wound is in a substantially full winding state on the winder side, as shown in FIG. When the winding is transferred from the first bobbin g to the second bobbin h, the cord f is dropped into the gap i between the bobbin g and the bobbin h, and the apparatus stops due to abnormal tension. is there. That is, in the fully wound state, the distance between the edge of the flange g ₁ of the bobbin g and the winding end is narrowed, and the cord f is not caught by the flange g _{1 of the} bobbin g, and the cord f is The traverse pulley k that carries from the first bobbin g to the second bobbin h has both bobbins g,
When passing between h, a drop of the code f occurs.

The present invention has been made in view of the above point, and an object of the present invention is to provide an automatic winding device that prevents a cord from dropping when a bobbin is switched.

(Means for Solving the Problem) In order to achieve the above object, the present invention provides first and second cords that are core bodies of a belt and are coaxially arranged in parallel at predetermined intervals. On the premise of an automatic winding device that continuously winds around a bobbin, a movable base movably disposed between the first and second bobbins, and a rotatably movably supported by the movable base.
