Abstract

PURPOSE:To enable smooth and reliable feed of parts, by a method wherein, in a titled device using magazine, a rotary table, longitudinally slidably holding a magazine, in inclined to force the forward end of the magazine into contact with a stopper at the end of a chute. CONSTITUTION:A magazine 1 on a rotary table 4 is pressed from above, the magazine 1 is logitudinally slidably held on the rotary table, and the rotary table 4 is turned in the direction of an arrow mark around a fulcrum 8. This forces the forward end of the magazine 1 into contact with a stopper 12, and with the rotary table 4 further turned, the magazine 1 is slid backward as it is brought into frictional contact with the stopper 12, and the magazine 1 and a chute 13 are completely interconnected. This prevents production of a gap between the magazine 1 and the chute 13, resulting in the possibility to reliably and smoothly feed parts.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a parts supply device that automatically supplies parts using a magazine in product assembly and the like.

(2) Purpose of the Invention An object of the present invention is to provide a component supply device that eliminates the gap between the magazine and the end surface of the sheet and can supply components smoothly and reliably.

(3) Structure of the invention The magazine is held so as to be able to slide back and forth on a rotary table, the rotary table is rotated and tilted, and the tip of the magazine is brought into contact with the end face of the chute, so that a gap is created between the two. There is a component supply device that is connected by eliminating the .

(4) Examples of the invention The structure of the present invention will be explained by way of examples.

FIG. 1 is a front view showing the entire parts supply device of the present invention. Parts 2 are stored in a magazine 1 in a line. A plurality of similar magazines are stacked on top of each other and guided by a magazine holder 3. First, the magazine 1 is pushed out from the front of an air cylinder (not shown) installed behind it in the direction toward the front in FIG.
is placed on top of it. A magazine presser 6 and a component presser 7 attached to the rotating table 4 are operated by the support arm 5, and press the magazine 1 and the component 2 from above with an appropriate force. Next, the rotary table 4 is rotated about the fulcrum 8 as shown in FIG. 2 by a rotary actuator (not shown) provided behind it.

The rotary table end portion 9 comes into contact with the seat stepped portion 10 and stops.

At this time, the magazine 1 is tilted forward by the rotation of the rotary table 4, and the magazine tip 11 comes into contact with the stopper 12 and is combined with the sheet 13. Next, the component holder 7 is released, and the component 2 and subsequent components that were being held down are moved to the magazine 1 by their own weight.
Slide down inside and move to chute 13. The part 2 then stops against the chute end 14 and is picked up from this position by a pick and place unit 15 and placed on a pallet 17 on a conveyor 16.

The pallet 17 is guided by a pallet guide 18 as shown in FIG. 3, and is conveyed to the next process by a belt 19. In the subsequent process, other parts 2Qa, 20
b, 20c, and 20d are assembled in sequence to produce a finished product (see Fig. 4) of unit parts used in high-frequency equipment.

The part 2 is a pressed product made of tin plate with a complicated shape as shown in Fig. 3. As shown in Fig. 5, if there is a gap 21 between the magazine 1 and the chute 13, the part will be damaged. The legs 22 fit into this, making it impossible to move parts from the magazine to the chute. The component supply device must be constructed so that such a gap 21 does not occur. However, magazine 1 has poor accuracy in length,
Since the magazine holder 3 is provided with a rearance 23 sufficient to allow each magazine 1 to fall smoothly, the position when the magazine 1 is pushed onto the rotary table 4 is at the first position.
In the figure, there is variation in the left and right direction, and if this is rotated as is, the above-mentioned gap may occur between the magazine and the shade.

Therefore, in the present invention, as shown in FIG. 6, the magazine 1 on the rotary table 4 is held down with a moderate force by a flat presser from above, and the magazine 1 is held so that it can slide back and forth on the rotary table 4. By setting the rotating shaft of the rotary table 4 at the fulcrum 8, when the magazine 1 is placed at the left position, the point 25 at the tip of the magazine will draw a curved line as the rotary table rotates. When the magazine l hits the stopper 12 at 27 and rotates further, the magazine l slides backward on the rotary table 4 and reaches the point. Further, when the magazine 1 is placed at the rightmost position, the point 25' at the front end of the magazine is similarly configured to reach point 4 via the track #26' and point 27. By doing this, the magazine can be tilted by just the rotational movement (one movement) of the rotary table 4, and at the same time, regardless of the position when the magazine 1 is pushed out onto the rotary table 4, the magazine and 7-- 13 can be joined without any gaps between them.

(5) Effects of the Invention The parts feeding device of the present invention holds a magazine on a rotary table so as to be able to slide back and forth, and by rotating and tilting the rotary table, the tip of the magazine can be used as a chute stopper. The end faces of the magazine and the end face of the chute are brought into contact with each other and connected with no gap between them, which has the effect of ensuring smooth and reliable supply of parts from the magazine to the chute. .
