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.

A centering device for such tire semi-finished products (PA) was disclosed in Korean Patent Laid-Open No. 10-2010-0097253.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a method of manufacturing a saddle- And it is an object of the present invention to provide a centering device equipped with a skew correction function for semi-finished products of a tire in which a skew correction is carried out on a length measuring conveyor and then the skew is conveyed to an applicator.

In order to accomplish the above object, the present invention provides a method of manufacturing an endless belt conveyor, comprising the steps of: conveying a side wall and an inner liner semi-finished product (PA) supplied by semi-finished bogie carriers on a semi-finished product conveyor, cutting them by a cutter, A centering device for the tire semi-finished products, in which a centering operation is carried out by means of a centering device, the semi-finished products being mounted between a cutter downstream of the conveyor and a length measuring conveyor, The calibration actuator is configured to rotate the length measuring conveyor about the hinge axis in the width direction.

The centering device having the meandering correction function of the tire semi-finished product according to the present invention detects the meandering by the meandering correction camera when the semi-finished product (PA) meanders when feeding the semi-finished product (PA) By adjusting the angle of the measuring conveyor to compensate for the skewness of semi-finished products (PA), it helps prevent quality degradation of the dynamic balance of finished tires caused by meandering of semi-finished products (PA) And it can also contribute to the improvement of the facility operation rate by unnecessarily requiring an artificial conveyor and an operation control operation as in the past for the skew correction.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view showing a conveyor system of a tire molding machine provided with a centering device having a skew correction function of a tire semi-finished product according to the present invention;
2 (A) through 2 (E) are flowcharts showing the centering process of the skew correction function of the present invention,
Fig. 3 is a side view showing a conveyor system of a conventional tire molding machine, corresponding to Fig. 1,
4 (F) to 4 (H) are flowcharts showing the centering process by the conventional conveyor system.

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, the semi-finished product (PA) is conveyed by the semi-finished conveyor (2) after the semi-finished products (PA) supplied by the supply conveyors (1a, 1b) are conveyed and cut by the cutter (3) And a centering alignment operation of the applicator (5) is performed using the actuator (7) according to a signal transmitted to the applicator (5) and provided by the centering camera (6), characterized in that the semi-finished product conveyor A skew correction camera 8 is mounted between a cutter 3 provided downstream of the length measuring conveyor 4 and an upstream side of the length measuring conveyor 4 and a skew correction actuator 9 for correcting the angle of the length measuring conveyor 4 The length measuring conveyor 4 is rotated in the width direction with the hinge shaft 10 as a point.

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 product PA supplied by the semi-finished product supply trucks 1a and 1b is transported on the semi-finished product conveyor 2, it senses 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 skew correction of the semi-finished product PA, the semi-finished product PA is scanned by the known centering camera 6 when it is conveyed from the length measuring conveyor 4 to the applicator 5 as shown in FIG. 2 (D) The centering alignment of the semi-finished product PA is performed by moving the applicator 5 from the dotted line position to the solid line position using the actuator 7 as shown in FIG. 2C, , And then the semi-finished product (PA), which has been subjected to the meander correction and centering alignment, is attached to the molding machine drum.

The centering device equipped with the skew correction function of the tire semi-finished product according to the present invention as described above is characterized in that the inner liner which is a semi-finished product of the tire, the meander of the semi-finished product (PA) obtained by using the skew correction camera 8 and the centering camera 6 By automatically performing calibration and centering alignment, improvements in equipment availability and accurate semi-finished (PA) transfers are made to improve the dynamic balance of finished tires.
