Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a centering apparatus having a meandering compensation tire of pre-

The present invention relates to a molding machine for molding a green tire, wherein when a pre-assembly (PA) of a side wall and an inner liner, which is semi-finished tire, is moved through a conveyor belt, To a centering device equipped with a skew correction function of a tire semi-finished product capable of correcting a sag deviation.

The green tire is formed by supplying the semi-finished material used for the tire to a molding machine and sequentially attaching the semi-finished material to the green tire. In the molding process of the green tire, And transferred to an applicator for guiding the semi-finished product PA of the liner to the molding machine.

3, sidewalls and inner liner semi-finished products PA, which are supplied through the semi-finished product supply trucks 101a and 101b, are fed to the semi-finished product conveyor 102 to be cut by the cutter 103, The finished semi-finished products PA are transferred from the length measuring conveyor 104 to the applicator 105 so that the semi-finished products PA are attached to the forming drum of the molding machine by the applicator 105.

At this time, when the semi-finished product (PA) is transferred from the length measuring conveyor 104 to the applicator 105, half of the semi-finished products PA passing through the LED lamp 111 through the centering camera 106 as shown in FIGS. The edge position is scanned and stored as data and the actuator 107 mounted on the lower portion of the applicator 105 is operated after the semi-finished products PA are transferred to the applicator 105, The centering alignment operation was performed as shown in FIG. 4 (H).

That is, the semi-finished product (PA) is calculated by (+) calculating the average value of the scan data and the offset data from the human-machine interface (HMI) A centering alignment operation is performed.

However, in the conventional centering device for a tire semi-finished product, it is impossible to automatically compensate for the skew of the semi-finished product (PA) of the sidewall and the inner liner, and an artificial conveyor angle adjustment operation There is a problem in that irreversibility occurs.

In order to solve the above problems, the present applicant has proposed a centering device of Korean Patent Application No. 10-2014-0097162, and the present invention is an improved technique of the above-mentioned Patent Application No. 10-2014-0097162.

A centering device for such a conventional semi-finished tire (PA) is disclosed in Korean Patent Publication No. 10-2010-0097253.

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

1 is a transport conveyor system of semi-finished products (PA) showing a centering device with a skew correction function of a tire semi-finished product according to the present invention, and Fig. 2 is an operational state flowchart of the present invention.

As described above, in the green tire molding operation, the semi-finished product (PA) of the side wall and the inner liner, which is a semi-finished product of the tire, is cut to a predetermined length and supplied to the applicator through the conveyor, PA) of the semi-finished products (PA) are attached.

In the present invention, semi-finished products (PA) fed by semi-finished product supply carriages 1a and 1b are conveyed on a semi-finished conveyor 2, cut by a cutter 3 and passed through a length measuring conveyor 4 A centering alignment operation of the applicator 5 is performed using the actuator 7 in accordance with the signal provided by the centering camera 6 when it is conveyed to the applicator 5, A skew correction camera 8 is mounted between the upstream side of the length measuring conveyor 4 and the upstream side of the length measuring conveyor 4 and the skew correction actuator 9 is provided for the angle correction of the length measuring conveyor 4 So that the hinge shaft 10 rotates in the width direction with respect to the point.

The centering camera 6 according to the present invention is provided with an operation sensor 12 for measuring the length of the semi-finished product PA cut by the cutter 3, So as to accurately cut the cut surface of the semi-finished product PA to be cut without cutting the cut surface.

An LED lamp 11 is installed between the semi-finished product conveyor 2 and the length measuring conveyor 4 and between the length measuring conveyor 4 and the applicator 5.

Next, a skew correction method for conveying a semi-finished product (PA) will be described with reference to the present invention.

When the semi-finished products PA supplied by the semi-finished product supply trucks 1a and 1b are transported on the semi-finished product conveyor 2, they sense the material of the semi-finished product PA transported as shown in FIG. 2 (A) The semi-finished product PA enters the length measuring conveyor 4 and scans the amount of change of both edge positions of the semi-finished product PA from the skew correction camera 8 when the length measurement is progressed.

The edge positions of the semi-finished product PA are both edge positions in the width direction of the semi-finished product PA passing through the LED lamp 11 at the left position (L-Position) and the right position (R-Position).

Therefore, the skew angle of the semi-finished product PA calculated by scanning the amount of change of both edge positions (R-position and L-position) of the semi-finished product PA from the skew correction camera 8, (PA) is cut off by the cutter (3), and after the completion of the length measurement of the semi-finished product (PA), a meandering correction is made on the downstream side of the length measuring conveyor (4) connected to the hinge shaft The operator 9 is operated to operate the length measuring conveyor 4 from the dotted line position to the solid line position as shown in Fig. 2 (C) to correct the meandering of the semi-finished product PA.

After the meandering correction of the semi-finished product PA, the semi-finished product PA is moved for measuring the length of the cut semi-finished product PA when it is conveyed from the length measuring conveyor 4 to the applicator 5 as shown in Fig. 2 (D) Centering alignment of the semi-finished products PA scanned and calculated by the centering camera 6 in which the sensor 12 is installed is performed. As shown in Fig. 2C, the applicator 5 is moved from the position The centering alignment of the semi-finished products PA is completed in a known manner, and then the semi-finished products PA having completed the meandering alignment and the centering alignment are attached to the molding machine drums.

In the centering device having the skew correction function of the tire semi-finished product according to the present invention, when the semi-finished product including the inner liner and the sidewall is fed, the cut surface of the semi-finished product is cut accurately by the heating cutter, Since the skew correction and centering alignment of the semi-finished product PA obtained by using the centering camera 6 equipped with the motion sensor 12 are automatically performed, it is possible to improve the operation efficiency of the equipment and to transfer the precise semi-finished product (PA) So that the dynamic balance can be improved.
