Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an automatic supply device for small parts, which press-fits small parts, such as a half-moon key, into the keyway of a workpiece that moves intermittently on an assembly line, for example. .

[Problems to be solved by conventional techniques and inventions] For example, when automatically supplying small parts having two mutually parallel surfaces on an assembly line,
In the automatic feeding device disclosed in Publication No. 21740, etc., small parts are stacked with their two mutually parallel sides joined together in a magazine installed near the assembly line, and the small parts are loaded as needed. One of the parts is pushed out in the direction of the assembly line using a push rod, and the small parts are sequentially supplied to the assembly line.

In addition, when press-fitting a small part such as a key into a keyway formed in a workpiece, Fig. 12 (plan view),
As shown in FIG. 13 (side view), the workpiece 1 is transferred horizontally, and the keyway 1a carved at the tip of the workpiece 1 is inserted into the guide rail 2a formed on the magazine base 2. Stop at that point. Next, the plunger 3a of the key supply cylinder 3 is operated to project, and the keep rod 4 connected to the tip of the plunger 3a is moved to the right in the figure.

The tip of this keep rod 4 is inserted into a guide rail 2a formed on the magazine base 2, and when the push rod 4 moves to protrude, the tip ends on the magazine 5, which is set upright on the magazine base 2. Push out one of the plurality of stored keys 6.

This pushed out key 6 is the guide rail 2
a in the horizontal direction, and is press-fitted into the keyway 1a carved in the workpiece 1.

Incidentally, recently, in order to improve the efficiency of the parts assembly process on an assembly line and to shorten the overall length of the line, a means for transporting a shaft-shaped workpiece 1 in an upright state has been adopted.

The keyway 1a of the workpiece 1 in this upright state
If the above-mentioned conventional device is used as is to perform the press-fitting process of the key 6, the guide rail 2a will be moved with the mutually parallel surfaces of the key 6 standing vertically. As a result, the key 6 cannot be held in position by the guide rail 2a, and the key 6 cannot be held in position by the guide rail 2a, and the key 6 cannot be held in its position by the guide rail 2a.
While moving in the direction, the key 6 becomes easier to rotate in the direction of movement, and the key 6 relative to the keyway 1a
The press-fitting position becomes unstable, causing problems in automating the work process.

A similar problem also occurs when the keyway or the recess into which the small parts are loaded is inclined.

[Purpose of the invention] This invention was made in view of the above circumstances.
It is an object of the present invention to provide an automatic feeding device for small parts that can feed small parts onto an assembly line in a stable position not only in the horizontal direction but also in a vertical or inclined position.

[Means for Solving the Problems] The automatic feeding device for small parts according to the present invention magnetically attracts the plate surface of a small plate-shaped part having a curved surface on the outer periphery and a pressing surface continuous to the curved surface. At the same time, there is a holding part that holds this plate surface in an upright state, and a holding part that is continuous with this holding part and attracts the board surface of the small plate-shaped component with magnetic force, and moves the curved surface in the direction of the assembly line while keeping it in an upright state. The device is equipped with a guide rail that guides relatively slidably, and a push rod that moves forward and backward along the guide rail and presses the pressing surface of the small plate-shaped component in the direction of the assembly line.

[Function] In the above configuration, the plate surface of the small plate-shaped part is held in an upright state by magnetic force on the holding part of the small part supply part, and then the press contact is applied continuously to the curved surface formed on the outer periphery of the small part. When the surface is pressed by the push rod, the small parts are transferred toward the assembly line while being attracted by magnetic force on the guide rail while maintaining the upright position.

Since the plate surface of the above-mentioned small plate-shaped part is always attracted by magnetic force when moving, the above-mentioned small plate-like part will not curve even if the pressing surface is pressed with the push rod while the plate surface is standing upright. It does not rotate in the plane direction and the posture will not become unstable.
