BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frying device that punches a textile fabric that makes up a carcass material that is part of a tire component. More specifically, it is easy to manage and freeze, as the frying shape of the textile fabric can be adjusted. An improved textile fabric frying device for carcasses that can prevent pricking off centers.

Among the components of the tire, carcass is a component that forms the skeleton of the tire with a cord layer inside the tire.

In order to manufacture such carcass, the textile fabric is first cut in the radial direction, and then subjected to a frying operation, wound on a trolley, and then used as a carcass material used in a molding machine.

In other words, as shown in FIG. 1, the textile fabric 2 wound around the let off machine is unwound and supplied and cut in the radial direction while passing through the cutter 3. The fryer 4 is spliced again and wound around the trolley 6 via a frying device 5 that punches the textile fabric 2 to be connected to the next process.

Here, the frying device 5 drills holes at regular intervals with a tool such as an awl in the carcass textile fabric 2, which removes the air introduced during tire forming to reduce defects due to the inflow of air into the finished tire. To do this.

Conventionally, such a fringing device 5 is installed in the transverse direction on the base 111 as shown in FIGS. 5 and 6 to correspond to the anvil roll 113 driven by the motor 112. There was provided a frying roll 114 with augment pins spaced at a distance in a straight array.

Therefore, the textile fabric 2 moves up and down the fringing roll 114 by the action of the up / down cylinder 120 when passing between the fringing roll 114 and the anvil roll 113 and thus the textile fabric 2 In the conventional frying device, the pins 121 are arranged on the fringing roll 114 so that adjustment is impossible, and each of the pins 122 has a switch. As it operates as a tire specification, the setting time of the carcass fabric used by tire naturally takes excessively, there was a problem that the work efficiency is reduced.

The present invention has been invented to solve the conventional problems as described above, it is possible to adjust the left and right adjustment interval of the flocking bunches to drill holes in the textile fabric is supplied, easy to manage and easy to set up work time to reduce productivity It is an object of the present invention to provide a textile fabric frying device for carcass that contributes to improvement.

In order to achieve the above object, the present invention provides an anchoring roll driven by a motor installed on a base for drilling holes in a textural fabric supplied from a let-off and a pinning corresponding to an upper portion of the anvil roll. In the frying device made of a roll, the frying roll is provided with a left and right moving rolls on the basis of the fixed center, and the left and right moving rolls are slidably moved along the guide rails in a left and right direction by a drive motor for transport, Each roll is connected with the corresponding left and right moving anvil rolls via a connecting frame.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 and 3 are a front view and a side view showing a frying device according to the present invention.

The present invention is provided with an anvil roll 13 installed in the base 11 to drive holes 22 in the textile fabric 2 supplied from the let-off 1, as shown in the drawing, driven by a motor 12. And a frying roll 14 having pins 21 correspondingly installed on the upper side of the anvil roll 13, wherein the frying roll 14 is left and right with respect to the fixed center roll 14a. Moving rolls 14b and 14c are installed, and the left and right moving rolls 14b and 14c are slidable in the left and right directions along the guide rail 17 by the drive motor 16 for transport, and the left and right moving rolls Each of the 14b and 14c is connected to the left and right moving anvil rolls 13b and 13c corresponding to each other via the connecting frame 18.

The fixed center roll 14a has a structure corresponding to the fixed center anvil roll 13a.

Accordingly, the left and right moving rolls 14b and 14c of the frying roll 14 are moved left and right along the guide rail 17 by the drive motor 16 for transporting, and the left and right moving rolls 14b and 14c The left and right moving anvil rolls 13b and 13c connected via the connecting frame 18 are also movable to the left and right along the axis 19.

On the other hand, when the textile fabric 2 is inserted in the direction of the arrow as shown in FIG. 3, the textile fabric 2 includes a frying roll 14 composed of the fixed center roll 14a and the left and right moving rolls 14b and 14c. It passes between the left and right moving anvil rolls (13b, 13c) and the anvil roll (13) consisting of the fixed center anvil roll (13a), wherein the respective pin lift and lower cylinders (20) installed on the frying roll (14). By the action of the textile fabric 2 is a hole 22 is punched as shown in FIG.

And if necessary, the formation of the holes 22 of the textile fabric (2) can be made by adjusting variously according to the carcass specifications.

As described above, the textile fabric frying device for the carcass according to the present invention can be finely adjusted in the fringing holes based on the center of the textile fabric during the fringing operation, and thus the quality control is easy and the setting method is easy to improve workability and productivity. This takes effect.
