JPS62130144A - Pneumatic absorbing device for intermittent rotary plate - Google Patents

Abstract

PURPOSE:To make it possible to pneumatically absorb only a table located at a predetermined position, by attaching shafts each having an air hole onto a rotary disc, by providing tables each having an air chamber to rotate them, and by providing a device for shutting off the air chamber of each table when the table comes to the predetermined position. CONSTITUTION:A shaft 2 having an air hole 2' connected to an air sucker 12, is provided on a rotary disc 1, and a plurality of shafts 2 having air holes are arranged in the upper section of the rotary disc. The shafts 2 are coupled to tables 3, 4, respectively. The tables 3, 4 are formed in their upper surfaces with several air holes 3', 4' which are communicated with air chambers 5, 5'. Air holes 6, 6' formed in the lower section of the air chambers 5, 5' are opened and closed by means of closable stoppers 7, 7'. With this arrangement, when one of the tables has come to a predetermined position, the stopper 7 shuts off the air communication while the stoppers in the tables at the other positions are opened so that air is sucked into the sucker 12 through holes 4', 6', 2'. Accordingly, it is possible to facilitate the absorption and removal of a workpiece.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an intermittent, rotating plate air suction device.

This invention will be explained with reference to the drawings. In the drawing (1) is the rotating plate (2).

') is a stop, (8) (8') is a stop shaft, (9) (9') is an arrow indicating the direction of movement of the stop shaft (8) (8'), (10) is a shaft fixing device, ( 11) is a packing, (12) is an air suction device, (13) is an air pipe, (14) is an arrow indicating the direction of air movement, (15) is an arrow indicating the rotation direction of the rotating plate (1), (16) ) indicates a table of arbitrary number of divisions, and A and B indicate the positions of tables (3) and (4).

Since the intermittent rotary plate air suction device according to the present invention is constructed as described above, the air suction device (12) and the shaft (2) are connected to the lower part of the rotary plate (1) using the packing (11) to suck air. A shaft fixing device (10) that prevents the rotation is connected with an air pipe (13), and a stopper (7) that moves up and down as shown by arrows (9) and (9') above the rotary plate (1) is attached. 7') with a stop shaft (

) (6'), and air holes (3') (4') are provided on the table (3) (4), and air is connected to the table (3) (4) using the connecting pipe (2'''). The air hole (2') is connected to the air hole (3') (
4') into the suction air chamber (5) (5'), and when the table (3) is stopped at position A, close the air stop hole (6) with the stopper (7) to allow air to circulate. and the stop (7') in the table (4) at position A on one side.
') to open the air stop hole (6') and let the air flow through the connecting pipe (2'''), the air hole (2') and the air pipe (3) as shown by the arrow (14). Suction machine(
12) and rotate the rotating plate (1) to the axis (2).
The table (3) at position A is moved to position B and stopped, and the table (4) at position (B) is moved to position A, and the movement of the stop shaft (8') releases air. In the same way as the air stop hole (6), the air stop hole (6') and the stopper (7') are combined to stop the flow of air.

Air is always sucked in one direction by the air suction machine (12), so the table (3) (4) that is stopped stops suctioning and while moving, both tables (3) (4) are always sucked in one direction.
), and an arbitrary number of dividing tables (16) can be attached as shown in FIG.

Conventional intermittent rotary plates could not suck air during rotation, but the stoppers (7) and (7') can switch between suction and stop, making it easy to attract and remove workpieces. Since it is simple, it can be manufactured at a low cost, and its structure is simple, so it can be manufactured at a low cost.
