JPS638158A - Stacking method for platelike work and device thereof - Google Patents

Abstract

PURPOSE:To make first-in first-out ever so easy, by installing a device, which makes a platelike work go up after conveying it horizontally up to the specified position, and another device which supports a lower surface of the work and regulates a position in the horizontal direction. CONSTITUTION:A platelike work 2 is carried in along a guide plate 1 by a front conveyor conveying it in direction at a right angle to a paper surface and stopped at the specified position. Next, holding stoppers 4 and 4 are rotated around a shaft 4a, supporting both sides from the lower side of the work 2. When the succeeding work 2 is conveyed and comes to the lower side of the preceding work 2, these holding stoppers are opened, and a lifting device 3 makes the work 2 go up together. Repeating this operation, when these work are stacked up to the specified height, a sensor 9 is set in motion whereby the lifting device 3 goes down, thus they are taken out from the uppermost work 2 in consecutive order in the opposite direction to the carry-in direction from a rear conveyor. With this constitution, first-in first-out is made possible to be done so easily.

Description

[Detailed Description of the Invention] [Summary] A method and apparatus for horizontally transporting plate-shaped workpieces such as printed wiring boards, stopping them at predetermined positions, and sequentially lifting them to one side and stacking them. It is.

[Industrial application field]

The present invention relates to a method and apparatus for stacking plate-shaped objects to be processed.

[Conventional technology]

Due to the recent rapid development of the electronics industry, the demand for printed wiring boards has reached an enormous amount. For this reason, automation and labor saving are being attempted in the manufacturing process, and first-in, first-out logistics in the processing process are desired.

[Problem to be solved by the invention] In the manufacturing and processing process of plate-shaped workpieces such as printed wiring boards, etc., when these workpieces are piled up at a certain height and processed by loft, it is easy to solve the problem. The goal is to achieve automated processing and labor savings by using efficient equipment and methods.

[Means for solving problems]

According to the present invention, there is provided a conveyor for horizontally transporting a plate-shaped workpiece, a means for stopping the transported workpiece at a predetermined position, and an elevating means for lifting the stopped workpiece upward. a holding stopper means capable of moving in and out of the vertical movement area of the workpiece to support the lower surfaces of both ends of the workpiece in the raised position; There is provided a stacking device for plate-shaped objects to be processed, characterized in that the device includes a regulating guide means.

Further, by using the above-mentioned device and retracting the holding stopper means from the area before the objects to be processed are lifted, the first object to be processed is stacked one after another on the object to be processed after -1-. A method for stacking plate-shaped objects to be processed is provided.

Furthermore, when a predetermined number of objects to be processed are stacked on the guide means, the holding stopper means is retracted from the area,
There is provided a method for stacking plate-shaped objects to be processed, characterized in that the predetermined number of objects to be processed are delivered to the rear of the predetermined position by the conveyor.

[For production]

According to the present invention, since the objects to be processed are stacked sequentially from the bottom, when a predetermined number of objects are stacked and processed for each round,
The first object to be processed is on the upper side, making it easy to achieve first-in and first-out.

〔Example〕

A rectangular plate-shaped workpiece 2 such as a printed wiring board with a constant dimension in the width direction (the length does not necessarily have to be constant) is
It is transported horizontally in the direction of arrow P while its position in the width direction is regulated by the front transport conveyor 6. Next, the object to be processed 2
is received by the central roller conveyor 5, and is conveyed horizontally in the direction of arrow P while its widthwise position is similarly regulated.
At a predetermined position R completely on the roller conveyor 5, the leading end abuts against the stopper 7, thereby being positioned and stopped. At this time, the drive of the conveyor 5 is also stopped.

On the other hand, above the predetermined position, there are two parallel guide plates 1 that regulate the positions of the previously stacked objects 2 in the width direction. It is supported by a holding stopper 4 that moves in and out from the direction (lit! direction perpendicular to the feeding direction P). Further, on the lower side of the conveyor 5, there is an elevator (elevating and lowering) for lifting the workpiece 2 at a predetermined position.
There is a refresher device 3. Therefore, the holding stopper 4 moves in and out of the vertical movement area of the workpiece 2 from both sides. The lifting device 3 and the holding stopper 4 are driven by a well-known cylinder. Further, the holding stopper 4 pivots about the fulcrum 4a.

The workpieces 2 in a predetermined position are once lifted by the lifting device 3 to a first position close to the holding stopper 4, and then the holding stopper 4 is opened, and the workpieces 2 that were previously stacked are moved to the new workpiece. Can be stacked on top of object 2. Next, the lifting device 3 is raised to the second position above the holding stopper 4 so that the lowermost surface of the workpiece 2 is slightly above the holding stopper 4. Next, the holding stopper 4 is closed and the lifting device 3 is lowered. As a result, the objects 2 to be processed are piled up with both ends being regulated in the width direction by the guide plates 1. By repeating this operation, the objects 2 to be processed are stacked one after another from bottom to top. The positions of the tips of these objects 2 to be processed are all the same.

In addition, when the support position of the workpiece 2 by the conveyor 5 and the position of the workpiece 2 by the holding stopper 4 are close to each other, the lifting device 3- is not driven in two stages as described above. , the holding stopper 4 may be opened and the previously stacked workpieces 2 may be stacked directly onto the workpieces 2 on the conveyor 5.

When a predetermined number of objects 2 to be processed are stacked, the object 2 on the uppermost stage touches a detection device 9 such as a microsinch attached to the guide plate 1. At this time, in order to carry out a certain number of stacked workpieces 2, the lifting device 3 is raised, the holding stopper 4 is opened, the workpieces 2 are temporarily transferred onto the lifting bag W3, and the lifting device 3 is transferred onto the conveyor 5 by lowering the conveyor 5 and the rear conveyor 8.
is carried out in the horizontal direction of arrow Q. In this case as well, the holding stopper 4 may be opened to directly transfer the workpiece 2 to the conveyor 5, as described above.

〔Effect of the invention〕

As described above, according to the present invention, with a simple structure, plate-shaped objects to be processed are stacked sequentially from the bottom, and it is possible to easily put them in first and take them out first.
