Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting a copper clad laminate used for manufacturing a printed wiring board.

[0002]

2. Description of the Related Art Conventionally, in the manufacture of printed wiring boards, the required thickness (for example, 35 μ) is applied to the surface of a substrate made of an insulating material.
It is well known that a so-called copper-clad laminate having a copper foil stretched thereon is used.

However, when cutting a copper clad laminate serving as an original plate of such a printed wiring board and carrying it on the production line after cutting, a conveyor provided with a pair of belt conveyors such as two or three. Belts are used.

Further, one of the paired belt conveyors is provided so as to be displaceable in the width direction with respect to another facing belt conveyor as a means for displacing the conveying direction. As a method of changing the conveying direction of the conveyor belt having the above configuration or the conveying line of the original plate, the original plate is once abutted against the reference guide side, temporarily stopped and aligned, and then the conveying direction is changed.

[0005]

However, the original plate transporting means having the above-mentioned structure has no problem if the original plate to be transported is properly placed on the conveyor belt. On the other hand, when it is placed in an inclined manner, since the means for correcting this placement state is not equipped, the original plate that is conveyed without being placed under the proper conveyance state falls on the conveyor belt. Or, the original plate is sandwiched by the belt, the original plate is damaged in the middle of transportation and the conveyance of the conveyor belt itself is obstructed, and the other original plates that are properly conveyed are also damaged. It was something that had.

Moreover, in the transfer line in which the change of the transfer direction in the transfer line is changed after the original plate is brought into contact with the reference guide side and aligned, it is a prerequisite that the original plate is properly placed on the line. As described above, if this is placed on the conveyor belt in an inclined manner, accurate alignment cannot be performed when it is abutted against the reference guide side, and not only the momentum and accurate direction change cannot be performed. , Damage to the original plate, and impair the proper operation of the configuration in the transport line, particularly in the component parts of the direction changing means (for example, if the original plate that has been tendered toward the reference guide side is directly abutted, The original plate interferes with the matching of the next original plate, spreads one after another, and causes the inoperability such that the original plates are mixed with each other in the direction changing component).

Therefore, the present invention was developed in view of the drawbacks in the method of transferring the original plate by the transfer line,
An object of the present invention is to provide a transportation method capable of correcting the transportation posture of the original plate during the transportation process to an appropriate posture.

Embodiments of the method of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an embodiment of a single width-shifting roller conveyor used in the method of the present invention, FIG. 2 is a side view of the same, and FIG. 3 is a plan view of a conveying device used in the method of the present invention. Reference numeral 1 denotes a base main body. The left and right side frames 2 and 3 are provided upright on opposite sides of the base main body 1 in the longitudinal direction, and the left and right side frames 2 and 3 are spaced apart from each other to form a plurality of reinforcing frames. It is constructed by stacking four.

Reference numeral 5 denotes left and right side frames 2 and 3 of the base body 1.
Width-shifting rollers rotatably mounted on a rotating shaft 6 rotatably installed at predetermined intervals between them, and between adjacent rollers of each roller 5 which are paired with each other, are fixed to an end portion 6a of each rotating shaft 6. They are connected by a connecting belt 8 stretched between the connecting pulleys 7. Each roller 5 is made of rubber or synthetic rubber.

Further, 9 is a rotation driving motor for each of the rollers 5 arranged on the upper side of the base body 1, and each motor 9 is for each rotating shaft 6 of one of the rollers 5 forming a pair. Driven pulley 1 fixed to the end 6b of the
A drive pulley 12 fixed to each drive shaft 11 of each motor 9 is connected to the drive shaft 0 via a connecting belt 13.

As shown in FIG. 2, the rollers 5 are axially attached to the left and right side frames 2 and 3 of the base body 1 so as to project from the upper side of the left and right side frames 2 and 3 and convey the original plate in advance.
It is desirable to have the same height as 0 (see FIG. 3) in the horizontal plane.

Now, the width-shifting roller conveyor alone 15 having the above-mentioned structure is arranged between the conveyors 21 and 22 of the belt conveyor 20 as a transfer line for the original plate 16, and the transfer method for correcting the original plate 16 in a proper attitude. Explaining in conjunction with FIG. 3, first, as shown in FIG. 3, the width-adjusting roller conveyer unit 15 is arranged between the conveyors 21 and 22 of the belt conveyer 20 along the straightening guide 23 side, which is arranged along the reference side conveyer 22. After arranging the drive pulleys 1 and 2, the drive motors 9 of the width-shifting rollers 5 are started to drive the drive pulleys 1.
