Next, the operation of the article supply device will be described with reference to FIGS.

FIG. 2 with the magazine 11 attached to the apparatus main body 1
In this state, the motor 26 of the pushing means 21 is operated to rotate the cam 25 in the clockwise direction.

When the cam 25 rotates 180 ° from the state shown in FIG. 2, the second rotation is caused by the rotation of the cam 25 as shown in FIG.
The lower end of the arm 24 is pressed to the right, and the second arm 24 swings counterclockwise about the shaft support. When the second arm 24 swings, the first magnet 23b
Since the first arm 23 is linearly held on the second arm 24 side with a predetermined holding force by the attraction between the first arm 23 and the second magnet 24b, the first arm 23 and the second arm 24 are also held. It swings in the same direction in synchronization with 24. The swing of the first arm 23 causes the push-out piece 22 engaging with the first arm 23 to advance in the push-out piece guide groove 4, and the tip of the push-out piece 22 is directed to the magazine 1.
1 is inserted into the insertion port 17. As a result, the rear end of the lowest article P1 is pressed, and the article P1 is pushed out of the discharge port 18 into the article guide groove 3.

From the state shown in FIG. 7, the cam 25 is further rotated by 180 °.
When rotated, as shown in FIG. 8, the lower end of the second arm 24 is pulled leftward by the attraction force of the third magnet 24c by the rotation of the cam 25, and the second arm 24 is pivotally supported. It swings in a clockwise direction around. Even when the second arm 24 swings, the first arm 23 is linearly held on the second arm 24 side with a predetermined holding force by the attraction between the first magnet 23b and the second magnet 24b. The first arm 23 also swings in the same direction in synchronization with the second arm 24. This first
When the arm 23 swings, the pushing piece 22 that engages with the first arm 23 retracts in the pushing piece guide groove 4, and the pushing piece 22 is withdrawn from the magazine 11 and returns to its original position. Then
Simultaneously with the completion of extraction, one article P in the magazine 11 is entirely lowered. The contact state between the second arm 24 and the cam 25 is always maintained by the attractive force of the third magnet 24c, including the return after the pushing.

When the above-mentioned pushing operation is repeated, the article guide groove 3 is filled with the article 3 as shown in FIG. 9, and the article P2 at the foremost end is exposed from the take-out port 3b. The article P is taken out from the supply device through the take-out port 3,
For example, it is performed by suctioning the article P2 at the position of the take-out port 3b with a suction pad (not shown). That is, by rotating the cam 25 once for each take-out, the next article P can be sequentially sent to the position of the take-out port 3b.

If the cam 25 rotates without taking out the article P2 at the take-out port 3b position in FIG. 9 due to a take-out failure or the like,
As shown in FIG. 10, in the initial stage of movement, the lower end of the second arm 24 is pressed to the right by the rotation of the cam 25, and the first arm 23 is also synchronized with the second arm 24. Although it oscillates in the clockwise direction, a resistance against the forward movement of the pushing piece 22 is applied, and at the same time, a force exceeding the holding force due to the attraction of the first and second magnets 23b and 24b acts on the first arm 23 to hold it. The first arm 23 is separated from the second arm 24 and remains in the same position, and only the second arm 24 swings counterclockwise. That is, when the holding by the attraction of the first and second magnets 23b and 24b is released, no force is applied from the pushing piece 22 to the articles P arranged in the article guiding groove 3.

From the state shown in FIG.
When it is rotated by °, the second arm 2 is rotated by the rotation of the cam 25.
The lower end portion of No. 4 is pulled leftward by the attraction force of the third magnet 24c, and the second arm 24 swings clockwise around the pivotal support portion. During the swing of the second arm 24, the second magnet 24b of the second arm 24 and the first arm 23
The first magnet 23b is attracted to the first arm 23 and the first arm 23 is moved to the second arm.
It is held again on the frame 24 side and returns to its original position.

Thus, in the above embodiment, the magazine 1
A discharge port 18 through which one stored article can be discharged is formed on one side surface of the end side of 1, and the insertion port 17 into which the pressing piece 22 of the pushing means 21 is inserted is formed smaller than the discharge port 18. Therefore, unless the magazine 11 is swung or the article P is pushed from the insertion opening 17 side when the magazine 11 is attached to the apparatus main body 1, the stored article P does not drop from the magazine 11 and the magazine 11 is attached. Work can be performed quickly and easily.

Further, since the insertion port 17 and the ejection port 18 are formed so as to have different sizes, the magazine 11 can be mounted in an appropriate direction by using the sizes of the ports 17 and 18 as a guide. There is no risk of mounting the magazine upside down like in.

Further, since the lid plate 16 constituting one side surface of the magazine 11 is configured to be openable and closable, the articles P can be easily stored by opening the lid plate 16 as appropriate, and the magazine 11 It is extremely useful when is repeatedly used.

The magazine according to the present invention includes a feeding device other than the one shown in the drawing, for example, one having a pushing means using a single swing arm, and a pushing means using a reciprocating forward / backward arm. It goes without saying that the invention can also be applied to other feeding devices having means. Also, the shape of the mounting part of the magazine is
