Abstract

PURPOSE:To make it possible to smoothly transfer a work at high-speed in the use of a rotary transfer mechanism of work by setting a work holder such as a spoon, etc. on a support member through a fixture and by lifting/lowring and rotating the support member through the traction/release motion of a traction member. CONSTITUTION:A support 2 is on standby in its approximately horizontal position. When a fixture member 4, which holds a work W with its holder 5, is sent out through a receipt/delivery section 16 of a machine tool 13, a cylinder rod 19 of a traction mechanism 7 goes in and down, and a traction member 6 is lowered through an up-and-down moving shaft 18. In this way, the tip of the support member 2 is shifted upward through a connecting member 8, and in the middle of the way the fixture member 4 is lifted up to the position on a temporary line, a rotating table 1 turns by 30 deg., the fixture member 4 faces the machine tool 13 on the next line, and, after it stops, the support member 2 is shifted downward. On the midway, the fixture member 4 is transferred to the receipt/delivery section 16 of the machine tool 13 and stops in the horizontal position at the descending end. The fixture member 4 is transferred to the machine tool 13, and the work W is machined as it is held.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a work rotary transfer device. As a conventional workpiece rotation transfer device of this type, the one shown in FIG. 3 is known.

In this structure, a plurality of support members 621 are provided protrudingly in a radial arrangement on a rotary disk I5υ, and these support members 64 are connected to a pivot point G3).
The support member 1521 + Futabakobe Kari also a is placed on the jig member 54), and the workpiece (W) is mounted on the jig member 54).
) (workpiece), in this case the spoon for eating and drinking is held in the holding part (
), and a plurality of processing machines (56), in this case, a buff roll grinding machine, etc., are arranged around the rotary disk 61J,
A receiving and sending part (57) is arranged in this processing machine 6Q, etc., and the rotary plate 6υ is reciprocated and rotated by the angle of the support member 6.
After swinging the jig member 4) upward, the jig member 4) is rotated, and after pivoting, the support member is rocked downward for 6 seconds to lower the jig member 641, and at this time, the receiving and sending part 67 ) to transfer the jig member (goods), then swing the support part 6 up while it is empty, and then rotate the rotary plate 6υ back to the return rotation position.
That is, the support member 6 is swung downward in the original position, and the receiving and sending section 7) transfers the force of the jig member G holding the workpiece ←) processed by the opposing processing machines 6 to the support member 4. The jig member 64) is received by swinging upward, and the jig member 64) is rotated again for the indexing part while holding the jig member 64). Machining the workpiece (b) with the opposing machining &266+,
Repeat this process and attach the jig member 64) to the workpiece (b).
It is designed to rotate and transfer.

In some cases, the rotary plate Gυ simply rotates in one direction intermittently, and in other cases, the support member 6 (2) is directly connected to the retainer part 6ω, thereby rotating and transferring the workpiece (B) while holding it. There are some things.

However, in the above conventional configuration, the earthwork rocking of the support member 6 is caused by a cylinder machine m in the center of the rotary disk 61).

By raising the wings of the member 6, the supporting member (52 and/or the jig member 4) swings downward under its own weight.

However, although this structure can be applied to a small number of stages with few processing machines, in the case of a large number of stages,
Due to the space available for processing machines (a), etc., it is inevitable that
The distance between the rotary disk C51) and the processing machine (a) becomes longer, and therefore the protruding length of the support member 62, especially the length from the pivot part (g) to the tip part, becomes longer, and this causes the pivot Department
The downward force on the pivot joint increases significantly, causing the operation at the pivot joint to become slippery, and when (- means the impact force), an unforeseen accident in which the pivot joint ruptures is likely to occur, and There is an inconvenience in that the supporting member 6 oscillates laterally due to inertial action after the rotary disk 51) is rotated and transferred.

The present invention aims to provide a work rotary transfer device that can eliminate these disadvantages.The gist of the present invention will be explained with reference to the accompanying drawings of FIGS. 1 and 2.
