Abstract

PURPOSE:To eliminate a mechanical driving part and to simplify the structure as well as to minimize the damage sticking of dust, etc. to an object, by drilling the vacuum holes to a single side face and the carrying end face of a carrying line to have a connection to a vacuum tube line. CONSTITUTION:An object 10 of a rectangular plate piece form floats up through a gas jetting hole 1a provided on the bottom surface of a carrying line when the gaseous nitrogen is supplied through a hose joint 7a and then carried until it contacts with the positioning pines 5c and 5d. The vacuum tube line connected to the hose joints 7b and 7c are opened while the object 10 stops at the pins 5c and 5d and floats up. Thus the vacuum reaches the vacuum holes 2a and 3a on the side face of the carrying line via the vacuum chambers 2b and 3b. Then the object 10 is sucked toward the positioning pins 5a, 5b, 5c and 5d to be positioned.

Description

[Detailed description of the invention] The present invention relates to a positioning device for rectangular plate pieces.

Conventionally, this type of positioning involves determining the target object.

Although this is done by moving and rotating the object in an appropriate direction using an external force, there are cases in which this cannot be done due to various problems such as damage to the object to be positioned or adhesion of dirt during the positioning process.

The present invention is aimed at automating machines as a countermeasure for such cases. The measuring device according to the present invention uses a positioning jig, a vacuum, and clean gas.

The positioning method according to the present invention will be described below with reference to the drawings as an example using a clean side body.The six positioning jigs have a gas ejection hole 1a opened toward the conveyance direction and , its gas passage 1b1 and positioning bins 5a, sb, 5c, 5. Guides @ 2, 5, 4, which form a conveyance path and serve as guides for objects are located above the sheet 1, which has 9 holes in which the objects are planted. Among these, the guide plate 2.3 has vacuum holes 2 & @ 3m for sucking the object from the conveyance path side, each pachyame chamber 2b, 3b, and each positioning bin 5a, 5b.

The implantation portions 5c and 54 are provided with recesses. Also shade 10
Gas passage 6a located on the lower surface and communicating with the gas passage 1b of the shade 1, the vacuum chambers 2b, 3bK of the guide plates 2, 3
Vacuum chambers 6b, 6C that communicate with each other, chute bottom plate 6 with fittings 7a, 7b, 7c for each pipe, positioning bins 5a, 5b, 5c, 5 (1, screws 8 for assembling each part)
There are also several screws 9 for attaching this positioning jig to the suitcase.

When the rectangular plate-shaped object 10 on the positioning jig is supplied with nitrogen gas from the hose joint 7a, the nitrogen gas passes through the gas passages 6a and 1b and is ejected in the transport direction from the gas jet hole 1a of the transport path**. Then, it floats up and the positioning bin 50
, 5dKali, the object 10
When it hits the positioning bins 5c and 5d and stops, and in the floating state, the vacuum hole connected to the hose joints 7b and 7cK is opened.

5c and 5d (at this point, the supply of nitrogen gas to the hose joint 7a is stopped and the object 1o is positioned. The graphite gas and the vacuum hole path are closed via a solenoid valve. 0 or more # activated by detection signal or timer cape signal!! As is clear, this positioning method does not require a mechanical drive unit and has an extremely simple and compact structure. Therefore, maintenance is easy, and there is less damage to objects or adhesion of bongs, etc., so it is effective even when the equipment has limited space.
