Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for loading a magazine in which a large number of perforated parts, such as washers, are stacked and stored.

When loading parts into a magazine that stores a large number of perforated parts in a stacked manner, special equipment is required if the storage holes are deep. For this reason, in the past, an operating rod with a tapered part for enlarging and contracting the slot was inserted into a guide bar with a slot at the tip, and the slot was expanded by the tapered part, and then a holed part was inserted into the guide bar. After stacking the guide bar around the outer circumference of the guide bar and inserting the guide bar into the component storage hole of the magazine,
A device is used in which the operating rod is axially moved by screw action or the like to reduce the slot and insert the component into the storage hole. This device had a problem that it had a complicated structure and was difficult to operate.

An object of the present invention is to provide a parts loading device that has a simple structure, is easy to operate, and is capable of reliably loading parts.

The structure of the present invention is such that the shaft is vertically passed through the sleeve with perforated parts laminated on the outer periphery so as to be relatively rotatable.
An eccentric shaft portion is provided at the lower end of the shaft to protrude from the lower end surface of the sleeve, and the eccentric shaft portion protrudes and retracts into two radial positions, radially inside and outside the sleeve, by relative rotation between the shaft and the sleeve. The present invention relates to a parts loading device in which a spring-like stopper is attached in a direction perpendicular to the axis of the shaft, and a rotation operation section is provided at the upper end of the shaft.

Embodiments of the present invention will be described below with reference to the drawings.
1 is a sleeve, and a perforated component 2 is laminated on the outer periphery of the sleeve. A shaft 3 is longitudinally passed through the sleeve 1 concentrically and relatively rotatably. At the lower end of the shaft 3, there is an eccentric shaft portion 4 that is eccentric with respect to the axis of the shaft 3.
is provided to protrude from the lower end surface of the sleeve 1, and a spring-like stopper 5 such as a snap ring is attached to the eccentric shaft portion 4 in a direction perpendicular to the axis of the shaft 3. The tip of this spring-like stopper 5 protrudes outside the diameter of the sleeve 1 when the eccentric shaft portion 4 is shifted to one side due to the rotation of the shaft 3, and is laminated on the outer periphery of the sleeve 1 as shown in FIG. It is in a position to receive the component 2 at the lowermost end, and when it is rotated 180 degrees and shifted to the other position, it is inserted into the diameter of the sleeve 1 and is displaced to a position where the component 2 can pass through, as shown in FIG. It has a length.

An engagement step 6 for preventing the spring-like stopper 5 from rotating is formed at the lower end of the sleeve 1.

Further, a rotation operation section 7 is attached to the upper end of the shaft 3. In addition, this rotation operation section 7, 180
゜In order to perform forward/reverse rotational positioning, a flange 8 is formed at the upper end of the sleeve 1 to face the lower surface of the rotary operation section 7.
Engagement grooves 9 are recessed at two positions of 2 degrees, and a positioning ball 10 that engages and disengages from the engagement grooves 9 is provided on the rotation operation unit 7 side.
and a spring 11 that presses the positioning ball 10.

Since the present invention has the structure as described above, a large number of parts 2 are stacked on the outer periphery of the sleeve 1, and the spring-like stopper 5 protrudes outside the diameter of the sleeve 1 and receives the lowermost part 2. As shown in the figure, the sleeve 1 and shaft 3 are inserted into the component storage hole 12, and from this state, the rotary operation unit 7 is rotated 180 degrees to remove the sleeve 1 and shaft 3.
When these are rotated relative to each other, they operate as shown in FIGS. 2 and 3. That is, as the rotary operating portion 7 rotates through 180 degrees, the eccentric shaft portion 4 rotates eccentrically through 180 degrees, and the tip of the spring-like stopper 5, which is prevented from rotating relative to the sleeve 1, is displaced into the diameter of the sleeve 1. Therefore, the parts 2 stacked on the outer periphery of the sleeve 1 slide on the outer periphery of the sleeve 1 and fall, and by pulling up the sleeve 1 together with the shaft 3 from the parts storage hole 12, the parts 2 are placed in the parts storage hole 12. They are stored in a stacked state.

As described above, the present invention has a particularly simple structure and is easy to operate due to the 180° forward and reverse rotation of the rotary operation part.The spring-like stopper is displaced within the diameter of the sleeve to prevent parts from falling. This has the advantage that parts can be loaded smoothly and reliably without getting caught on the spring-like stopper.
