[Industrial use]

The present invention relates to a case transfer device for transferring the case molded in the primary molding machine to the shaping drum of the secondary molding machine, in particular the labor load of the worker is transferred by the case transfer device the case was transferred by the manual operation of the conventional worker The present invention relates to a case transfer device of a tire molding machine which is greatly reduced and the working time is shortened to improve productivity.

Conventional Technology and Issues

As is well known, the manufacture of tires is largely classified into a preparation process for tire materials, a forming process of tires, and a vulcanization process of tires. The forming process of tires includes various members prepared through a preparation process for tire materials. It is assembled to finally make a green tire, and the molding machine used in this molding process is a primary molding machine that generally integrates the beads, the inner liner, the carcass and the side wall to make a case that is an intermediate product of the tire, After the belt and the tread are integrated, the intermediate product and the case are integrated to form a secondary molding machine for making a semi-finished green tire.

3 is a view showing the primary molding machine, (a) is a side view, and (b) is a cross-sectional view of the line I-I of FIG. 3 (a). In this case, the beads are inserted into the bead setter 3 installed on the headstock 2 by hand, and the inner liner is wound on the carcass drum 4 from the service 8, and the carcass is removed from the servicer 8. Is wound on the carcass drum (4), → splicing the joints of the carcass, → the tailstock (6) is moved to the carcass drum (4) by the feeder (5), → bead setter (3) , 7) the bead is positioned on the circumference of the carcass and the carcass and innerliner attachments are turned up (the internal bladder of the beadset is expanded so that the bead becomes the carcass and innerliner attachments). Wrapped), → the tailstock (6) is returned to the win position by the feeder (5), → the rain is installed on the tailstock (6) by hand Insert the bead into the setter (7), → The sidewall is wound from the assistant (8) to the carcass drum (4), → The sidewall is jointed and spliced (Splicing) → The sidewall is formed by the stitcher (10) Stitching, → carcass drum (4) is retracted into the circumference of the case, → the case is removed manually from the carcass drum (4), → the case is transported by hand (see Fig. 4). ), Loaded into,

4 is a view showing the secondary molding machine, (a) is a side view, and (b) is a cross-sectional state diagram of the II-II line of (a) of FIG. In this case, the case transported along the conveying conveyor 30 by hand is inserted into the sleeping drum 15, → the belt is wound from the service 17 to the belt drum 13, and → the service by hand. Insert the tread into (17), → The tread is wound from the servicer (17) to the belt drum (13), → The belt with the tread added to the outer circumferential surface by the belt transfer is transferred from the belt drum to the sleeping drum (15). And stitching, green tires are produced.

On the other hand, Figure 5 is a prior art, a planar working arrangement in which the primary molding machine, secondary molding machine and the transfer conveyor is installed, bar (a) is the first embodiment, (b) is the second embodiment.

As described above, in order to mold the green tire using the primary molding machine and the secondary molding machine, both the work using the accessory and the various jig of the molding machine and the manual work of the operator are required.

The other work during the manual operation of the worker is not very difficult because the labor load is not so large, but the transfer of the case requires a large labor force of the worker by the weight of the case.

However, as shown in FIG. 5, the conveying conveyor 30 is used as the apparatus for conveying the case in the first and second embodiments. The labor load of the worker is increased by the worker having to manually take out the work to insert the case loaded on the conveying conveyor 30 into the conveying conveyor 30 and to load the conveying conveyor 30 from the drawing conveyor 15. There was a problem in that the productivity is reduced.

[Purpose of invention]

Accordingly, the present invention has been made in order to achieve the above object, the object of the present invention is to provide a case transfer autonomous of the tire molding machine to greatly reduce the labor load of the worker and shorten the working time to improve productivity have.
