[0002]

2. Description of the Related Art A conventional parts feeder is a rotary plate composed of a single plate, and a plurality of shifting plates are provided from a central portion to an outer peripheral direction at a predetermined angle with respect to a radial direction. Are moved to the outer peripheral side along the approach plate, aligned, and discharged.

A force is applied to the moving plate in the moving direction of the parts, but since the rotating direction of the rotary plate is constant, the force applied to the moving plate is always applied in a constant direction, and the mounting angle of the moving plate is adjusted. If the component is defective, the component may not be smoothly guided, and the component may be defectively discharged, or the component may be jammed due to the component and the component may be damaged.

More specifically, a horizontal driven pulley in which a central axis perpendicular to the bottom plate of a container made of a cylindrical body having a bottom plate is erected, and a plurality of inner peripheral surfaces are supported by bearings above the bottom plate. Is provided concentrically with the central shaft, and an endless belt is hung on the driven pulley, which is fixed to the rotary shaft of the motor outside the container, and a turntable having a central hole on the driven pulley. A track plate made of an annular plate having an outer diameter slightly smaller than the inner diameter of the cylindrical body is provided above the outer circumference of the turntable, and a ring-shaped ring having a central hole fitted on the center axis is provided on the turntable. The external tooth sun gear is attached, the central block is attached to the upper part of the central axis, and the planetary gears that mesh with the sun gear are attached to several points on the lower surface of the central block. Above the turntable, a central hole is fitted in the central block, and a field plate having an outer diameter slightly smaller than the inner diameter of the track plate is provided such that the track plate and the upper surface are flush with each other. An inner ring gear that meshes with the planetary gear is attached to the lower surface of the field plate, and a base portion of a shifting plate that extends to the inner wall surface side of the cylinder so as to cross the field plate and the track plate is attached to the center block as appropriate.

A radial bearing 23 is provided between the shaft and the shaft.

As shown in FIG. 6, the upper and lower ends of the inner ring 23a of the radial bearing 23 are sandwiched between the lower end flange 22a of the stop shaft 22 and the spacer 22b fitted to the stop shaft, and the planetary gear 21 is attached to the outer ring 23b. It is glued or press-fitted.

Above the turntable 13, a field plate 24 having a central hole fitted in the central block 19 and having an outer diameter slightly smaller than the inner diameter of the track plate 14 is provided between the track plate 14 and the upper surface. They are provided so that they are flush with each other, and the mounting structure is as follows.

Shafts 25 are set up at several places, for example, four places on the same circumference of the turntable 13, and radial bearings 26 are horizontally supported on the respective shafts, and on the lower surface of the field plate 24. Guide ring 2 provided with screws 27
A field plate 24 is rotatably provided above the turntable 13 by fitting an outer ring of the radial bearing 26 in the inner circumferential groove of the turntable 8. On the lower surface of the field plate 24, the internal ring gear 2 that meshes with the planetary gear 21 is formed.

A gutter-shaped chute 32 extending in the tangential direction of the plate is provided, and the inner bottom surface of the chute is flush with the upper surface of the track plate.

[0019]

Since the parts feeder according to the present invention has the above-mentioned structure, the following effects can be obtained. That is, in the above-described embodiment, when the motor 8 is rotated, the field plate 14 and the track plate 24 are moved to the position shown in FIG.
It is rotated horizontally in each opposite direction as shown in.

When a work 33 such as a machine part is put into the container 1, the work on the track plate is directly conveyed by the track plate and discharged from the chute 32 to the next process section outside the container.

The work on the field plate 24 is rotatably transferred together with the field plate, but when it hits the moving plate 31, it is guided by the moving plate and moved in the radial direction of the container to be transferred onto the track plate 14. , And is conveyed by the track plate and discharged from the chute 32 to the next process section.

Therefore, the parts feeder of the present invention needs only one moving plate, and the parts can be transported smoothly without being jammed by the moving plate. It has the advantage that it can be used as a long product.
