Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a feeding device for a rectangular or square thin plate material, such as a printed circuit board.

(Prior art) As a conventional technology, there is a structure shown in FIG.

That is, a pair of guides 2 and 3 facing each other are provided on both sides of the belt conveyor 1, and each of these guides 2 and 3 is connected to a large number of rectangular and thin plate materials that are placed in parallel on the belt conveyor 1 and transported. Placed close to both sides of the workpieces 4, 4a, 4b, 4c...
As a result, for example, when the workpiece 4 is being conveyed by the belt conveyor 1 while cutting grooves on its surface, the guides 2 and 3 restrict the movement of the workpiece in the width direction on the belt conveyor 1. Something was hot.

(Problems to be Solved by the Invention) In general, a workpiece made of a thin plate material is easily deformed, so even if it is divided into squares by the same means, a slight dimensional error will occur in the length of each side.

When feeding such workpieces, the above-mentioned conventional method requires the width of each workpiece 4a to 4c placed on the belt conveyor 1, that is, the third width, as shown in FIG.
In the figure, the width of the workpiece 4 is different in the vertical direction.
A gap may be generated between the workpiece 4 and the guides 2 and 3, or the workpiece 4 may be strongly pressed by the guides 2 and 3 and bent.

For this reason, when machining the surface or end face of a workpiece while it is being transferred, conventional methods have had the disadvantage that high-precision machining is difficult.

The object of the present invention is to provide a novel rectangular thin plate feeding device that eliminates the above-mentioned drawbacks.

(Means for solving the problems) In order to achieve the above object, the present invention is constructed as follows.

That is, a pair of guides facing each other is provided on both sides of the conveyor, and on both sides of a rectangular thin plate workpiece to be placed on the conveyor and transferred.
In the rectangular thin plate feeding device in which the respective guides are arranged close to each other, one guide is provided with a cutter on the transfer start end side of the conveyor that contacts the end surface of the workpiece that the one guide faces. This is what I did.

(Function) Since the present invention has the above-mentioned configuration, each workpiece placed on the conveyor has its end face facing one of the guides sequentially contacting the cutter immediately before it is fitted into the guide, and the workpiece is moved by the cutter. After being cut, it will be inserted into the guide.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

First, in the drawings, FIG. 1 is an explanatory plan view showing the basic structure of the present invention, and FIG. 2 is a perspective view showing an embodiment in which the present invention is applied to a printed circuit board processing machine.

In FIG. 1, reference numeral 5 denotes a flat belt-type conveyor extending horizontally in the left-right direction, and a pair of guides 6 facing each other are provided directly above the conveyor 5 on both sides (vertical direction in FIG. 1). , 7 are provided.

Works 8 are placed in series on the conveyor 5, and are made of thin plates, such as printed circuit boards, cut into squares or rectangles.

Of the guides 6 and 7, a disc-shaped cutter 9 that rotates around a vertical axis is arranged on the left side of one guide 7, that is, on the transfer start end side of the conveyor 5.

This cutter 9 is placed slightly inward from the inner edge 7a of the one guide 7 so that it comes into contact with the end surface 8a of the workpiece 8 that the one guide 7 faces.
That is, it is arranged so as to protrude in the direction of the other guide 6.

As a result, when each workpiece 8 placed on the conveyor 5 is transferred in the direction of arrow A, one guide 7
Cut the end surface 8a of the work 8 just before entering the
The width L1 of each work 8 is the gap L2 of each guide 6, 7.
roughly correspond to

Next, FIG. 2 will be explained.

Reference numeral 10 denotes a conveyor consisting of a flat belt wound around drums 11 spaced apart in the left-right direction. Reference guide 12 and movable guide 1 facing it
3 will be provided.

The movable guide 13 has its left and right ends screwed into feed screws 14, 14 extending in a direction orthogonal to the rotating direction of the conveyor 10.

Further, the feed screws 14, 14 are connected via bevel gears 15, 15 to a drive shaft 16 arranged parallel to the movable guide 13, and a handle 17 is attached to the left end of the drive shaft 16.

Thereby, by rotating the handle 17 forward and backward, the movable guide 13 is moved toward and away from the reference guide 12 in parallel to the reference guide 12 via the drive shaft 16 and the feed screw 14.

Further, a roller support bar 18 extending in the left-right direction is connected to the reference guide 12, and a large number of pressing rollers 19 are attached to the roller support bar 18 at a predetermined pitch in the direction in which the reference guide 12 extends. . This pressing roller 19 is located directly above the edge of the conveyor 10 facing the reference guide 12, and presses a workpiece 20 made of a printed circuit board or the like placed on the conveyor 10.

A spindle head 21 is fixed upright on the left end of the movable guide 13, and a cutter 22 that rotates around a vertical axis is attached to the lower end of the spindle head 21.
Place.

This cutter 22 is arranged so as to project slightly inward from the inner edge 13a of the movable guide 13, that is, in the direction of the reference guide 12, so as to contact the end surface 20a of the workpiece 20 that the movable guide 13 faces.

Thereby, when each workpiece 20 placed on the conveyor 10 is transferred in the direction of arrow A, the end surface 20a of the workpiece 20 is cut immediately before entering the movable guide 13, and the width of each workpiece 20 is made constant.

In FIG. 2, reference numeral 23 denotes a grooving cutter, which is disposed at a longitudinally intermediate portion of the conveyor 10 and forms a V-groove 20b extending in the left-right direction on the upper surface of the workpiece 20 that has arrived at this portion.

This V-groove is for dividing the workpiece 20 in a subsequent process, and is for determining the planar shape of the workpiece at the time of production.

(Effects of the invention) As is clear from the above description, according to the invention, each workpiece supplied to the conveyor has its end face facing one guide sequentially contacting the cutter immediately before it is inserted into the guide. After being cut by the cutter, it is inserted into the guide.

Therefore, each workpiece transferred to the guide section
They all have a uniform width, are guided smoothly and stably by the guide, and when processing a workpiece during transportation, the processing can be performed with high precision.
