DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for aligning a thin cylindrical work.

[0002]

2. Description of the Related Art Thin cylindrical workpieces 2 such as piston rings and inner and outer rings of rolling bearings are usually transported and stored in a state of being inserted into alignment rods 4 as shown in FIG. It is set on the attachment device. As a device for inserting the work 2 into the alignment rod 4, a combination of a tongue 6 and a belt conveyor 8 is generally used. In this apparatus, the work 2 is conveyed to the stopper 10 at the end of the belt conveyor 8, lifted by the tongue 6 and carried to the upper end of the alignment rod 4, dropped by opening the tongue 6, and inserted into the alignment rod 4. You.

[0003]

If the work is particularly thin and soft, such as a piston ring, the work may be deformed by the clamping force of the tongue. Further, there is a problem that the moving mechanism of the tongue and the opening / closing mechanism of the claw are complicated, and if the position of the alignment bar is changed, the moving mechanism of the tongue must be significantly modified.

SUMMARY OF THE INVENTION An object of the present invention is to provide a thin cylindrical work which can be inserted into an alignment rod without gripping the work, is structurally simple, and can easily cope with a change in the position of the alignment rod. It is to provide an alignment device.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an inclined gutter capable of rolling and moving a thin cylindrical work, and forming a stopper at a lower end of the inclined gutter. ,
A work outlet is formed on a side wall of the inclined gutter adjacent to the stopper portion, and a bottom wall of the inclined gutter facing the outlet is inclined toward the outlet side, and is inserted into a center hole of the work laterally and downward of the outlet. The upper end of the possible alignment bar was located.

[0006]

The work supplied to the inclined gutter rolls down the inclined gutter by its own weight, stops at a stopper, and then falls down toward the outlet of the work due to the inclination of the bottom wall of the inclined gutter. On the way down from the exit, it is accepted by the alignment bar.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an apparatus for aligning a thin cylindrical work. In FIG. 1, reference numeral 12 denotes a gently inclined work for rolling a thin cylindrical work 2 such as a piston ring or inner and outer rings of a rolling bearing. 2B, and an inclined gutter having a U-shaped cross section. A supply passage (not shown) for supplying the work 2 one by one is connected to the upper end of the inclined gutter 12, and a plate-like stopper 14 is provided at the lower end of the inclined gutter 12. . One side wall 12a of the inclined gutter 12 adjacent to the stopper portion 14 is cut out to form an outlet 16 of the work 2, and the bottom wall 12b of the inclined gutter 12 facing the outlet 16 is
The work 2 on the bottom wall 12b is inclined toward the outlet 16 by an angle θ that is sufficient to cause the work 2 to fall down to the outlet 16 side. The upper end 4a of the vertical alignment rod 4 is positioned at a position beside and below the outlet 16.

Next, the operation of the above-described alignment device will be described. The work 2 supplied from the supply passage (not shown) to the upper end of the inclined gutter 12 rolls downward in the inclined gutter 12 by its own weight, hits the stopper portion 14 and stops instantaneously, and thereafter, the bottom wall 12b As shown in FIG. 2 (A), it falls down from the inclined gutter 12 as shown in FIG. 2A, and is inserted into the alignment rod 4 in the course of this fall. Subsequent workpieces 2 also fall from the outlet 16 one after another and are sequentially inserted into the alignment rods 4.

[0009]

As described above, according to the present invention, the work is dropped from the outlet at the lower end of the inclined gutter while falling down, and is inserted into the alignment rod during the fall. There is no deformation due to the structure, and the structure is simple because there is no need for any power means, so the equipment cost and maintenance cost can be greatly reduced. It is possible to correspond to.
