Description

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 having the above is used.

However, when cutting a copper clad laminate serving as an original plate of such a printed wiring board and carrying it in 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 belt conveyor which is opposed, as a means for displacing the conveying direction. As a method of changing the conveying direction of the conveyor belt having the above-mentioned 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 conveying means having the above-mentioned structure has no problem if the original plate to be conveyed is properly placed on the conveyor belt. On the other hand, if it is placed in an inclined manner, the original plate conveyed without being placed under the proper conveying condition falls on the conveyor belt because there is no means for correcting this placed condition. However, if the original plate is sandwiched between the belts, the original plate will be damaged during transportation and the conveyor belt itself will be obstructed from being conveyed, and other original plates that are properly conveyed will also be damaged. It was something that had.

In addition, in the transfer line in which the change of the transfer direction in the transfer line is changed after the original plate is abutted against the reference guide 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 with a tendency, accurate alignment cannot be performed when it is abutted against the reference guide side, and not only can momentum be accurately changed. , Damage to the original plate, and impair the proper operation of the configuration of the transport line, especially in the component parts of the direction changing means (for example, if the original plate tending to be transferred to the reference guide side is abutted as it is, 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 attitude of the original plate during the transportation step to an appropriate attitude.

[0008]

The transport method according to the present invention comprises two steps.
In a transport method for transporting a copper clad laminate for a printed wiring board by a belt conveyor constituted by a plurality of conveyors such as a pair of three or more conveyors, it is arranged along either the left or right transport direction of the belt conveyor. The printed wiring board copper clad laminate for straightening while conveying while guiding with a straightening guide, between the conveyors of the belt conveyor, the straightening roller conveyor alone arranged to tend to the straightening guide side, The copper clad laminate for a printed wiring board, which is being conveyed by the belt conveyor, is conveyed while being width-shifted to the correction guide side.

[0009]

According to the method of the present invention, the original plate can be conveyed while being corrected to a proper posture by the belt conveyer.

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 is a base body, and left and right side frames 2 and 3 are provided upright on both left and right sides in a length direction of the base body 1, and the left and right side frames 2 and 3 are provided with a plurality of reinforcing frames at intervals. It is constructed by stacking four.

Reference numeral 5 denotes left and right side frames 2 and 3 of the base body 1.
A width-adjusting roller rotatably mounted on a rotary shaft 6 rotatably installed at predetermined intervals therebetween, and between adjacent rollers of each roller 5 which are paired with each other, are fixed to an end 6a of each rotary 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 the respective rollers 5 arranged on the upper side of the base body 1, and the respective motors 9 are the respective rotation shafts 6 of the one roller 5 forming a pair of the respective rollers 5. 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, each roller 5 is pivotally attached to the left and right side frames 2 and 3 of the base body 1 so as to project downward from the upper side and conveys 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 serving as a transfer line for the original plate 16, and a transfer method for correcting the original substrate 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 disposed between both 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 9 in such a manner that they tend to
2. While rotating each rotary shaft 6 via the driven pulley 10 and rotating each other rotary shaft 6 paired with this via each connecting pulley 7, each width-shifting roller 5 is moved to the belt conveyor 20. Rotate in the direction corresponding to the transport direction.

However, when the original plate 16 placed and conveyed on both the conveyors 21 and 22 of the belt conveyor 20 reaches the portion where the width-adjusting roller conveyor unit 15 is disposed, the guides 23 are rotated by the respective width-adjusting rollers 5. By the side-to-side alignment and the width-wise alignment, for example, the original plate 1
6 is not in an appropriate posture between the two conveyors 21 and 22, and is placed at an angle, the guide 2
It is possible to correct the original plate 16 in an appropriate posture while keeping the width toward the 3 side.
