Description

[Detailed Description of the Invention] The present invention relates to a device for aligning workpieces in a certain direction for use in painting processes and the like.

Conventionally, as shown in FIG. 3, an engaging arm b is attached to a trolley conveyor a in three directions at an angle of 90 degrees.

An indexer e having indexes c and d is rotatably provided, a hanger f is attached to the indexer e, and the work g is transferred by hooking the work g onto the hanger f.

In order to align the workpieces g facing in different directions as shown in FIG.
The work g was aligned in one direction by engaging the indexer pole h.

In this case, when the conveyor speed is high, the engagement arm b
, C, and d collide with the indexer pole h with a large impact, causing overturning of the workpiece g, vibration, etc., which is disadvantageous in terms of durability.

Furthermore, in order to stop the rotation every 90 degrees, the indexer
It is necessary to attach an indexing mechanism to the indexer pole, and it is troublesome to manage the dimensions of the engaging arms b, c, d and the indexer pole in the vertical direction.

The present invention eliminates the above-mentioned problems and provides a workpiece aligning device that can soften the impact during direction regulation and smoothly rotate the workpiece.

Hereinafter, FIG. 1 of the accompanying drawings showing one embodiment of the present invention,
This will be explained with reference to FIG.

In the figure, 1 is a trolley conveyor, 2 is a rail, and 3 is a trolley conveyor.
is a roller.

Reference numeral 4 denotes a hanger rotatably provided on the conveyor 1, and has an S-shaped curved portion and an indexer retaining portion 6 offset from the rotation fulcrum 5.

Reference numeral 7 denotes a disc-shaped indexer arranged offset from the rotational fulcrum 5, and the indexer-engaging portion 6 abuts the outer circumferential surface of the indexer 7 so that the rotational fulcrum 8 is centered around the rotational fulcrum A of the hanger 4. While rotating on its own axis, it revolves around the outer periphery of the indexer, and is in a positional relationship in which it separates along a tangent to the outer periphery of the indexer in approximately the same direction as the direction in which the conveyor travels.

Next, referring to FIG. 2, the operating condition of the above-mentioned configuration will be explained.

As the hanger 4 approaches the indexer 7 in different directions, the indexer engaging portion 6 comes into contact with the outer peripheral surface of the indexer 7, thereby rotating the indexer 7 in the direction of arrow M, and the hanger 4 itself approaches the indexer engaging portion. 6 revolves around the outer periphery of the indexer 7 while rotating around the rotation fulcrum 5.

Finally, the tangent line T-T' with the outer peripheral surface of indexer 7
It separates from the outer circumferential surface of the indexer 7 along the same direction.

Here, the tangent TT' is substantially in the same direction as the traveling direction of the conveyor 1.

In this way, the indexer retaining part 6 is attached to the indexer 7 along the tangent line T-T' in the same direction as the traveling direction of the conveyor 1.
It separates from and aligns in one direction.

Therefore, unlike the conventional case, the impact for rotating the hanger 4 is small, there is no overturning even if the speed of the conveyor 1 is high, and there is no need for an indexing mechanism or the like.

As is clear from the above embodiments, the work alignment device used in the painting process of the present invention is equipped with a hanger for supporting the work rotatably attached to a transport means such as a trolley conveyor, and this hanger is rotatable. An approximately disk-shaped indexer having an indexer engaging portion offset from a fulcrum and a rotation fulcrum offset from the rotation fulcrum,
The above-mentioned indexer retaining portion contacts the outer circumferential surface of the indexer, rotates and revolves, and separates from the indexer along the tangent line that makes line contact with the outer circumferential surface of the indexer, which is in almost the same direction as the direction of travel of the conveyor. Because of this, it has various advantages such as there is no shock during rotation unlike the conventional method, smooth workpiece alignment is possible, and it is most suitable for automated painting processes.
