A weight having an appropriate weight (not shown) is placed on the uppermost part of the stick, and a stick 1 for stick ejection and replacement, which will be described later.
You may make it promote fall movement below 0.

A cylinder 23 is provided corresponding to one opening end of the lowermost stick 10 of the plurality of sticks stacked between such stick guides 21 and 22. In the cylinder 23, a piston or a pusher 12 as a pressing operation member for pressing and moving a component is housed. Pusher 12 is stick 1
It is formed in an outer shape along the inner shape of 0, and its dimension is selected as a numerical value that allows less leakage of air (driving air to be described later) and that can move smoothly (smoothly) inside the stick 10. This pusher 12 is, for example, shown in FIGS.
As shown in (1), a rod-shaped pusher rod 13 may be provided at the tip. The pusher rod 13 is attached to an optimum position for pushing the component 11.

As shown in FIGS. 5 and 6, for example, the cylinder 23 is configured such that the groove in the cylinder body 23a communicates with the cavity of the stick 10 by attaching a lid 23b to the cylinder body 23a having the groove. Have been. The air supply port 2 provided at the end of the cylinder 23
By driving the pusher 12 with air pressure by supplying high-pressure air from 4, the pusher 12 moves in the direction of arrow B,
The tip of the pusher rod 13 presses the electronic component housed in the stick 10 to transfer it in the direction of the arrow B.

1 to 3, the pusher 12 moves in the direction of arrow B while pressing the electronic components in the stick 10 so that the foremost electronic component 11 in the stick 10 is moved to the electronic component supply portion 27 of the cylinder 26. Arrives at the point of contact and comes into contact with the sliding block 28 as a stopper, the supply of high-pressure air is stopped, and the electronic component insertion device or the component mounting device waits for a component to be picked up by a chucking (gripping) means or the like. State. When the electronic component 11 sent to the component supply unit 27 is taken out (picked up) by an electronic component insertion device or the like, high-pressure air is sent again from the air supply port 24 and the operation of pushing out the electronic component 11 is repeated. At this time, the pusher 12
The inside slides by the length of the electronic component 11. The pressure of the high-pressure air can be adjusted by a so-called regulator.

There are various types of support structures for these parts. In the illustrated embodiment, for example, a vertical plate 32 is attached to a base 31 that is placed horizontally, and the vertical plate 32 is attached to the vertical plate 32, for example, as described later. A horizontal support plate 34 is attached via a sliding plate 33 to be moved, and the cylinder 2 is mounted on the horizontal support plate 34.
3 is fixedly supported, and the cylinder 26 is fixedly supported on a horizontal support plate 35 attached to a vertical plate 32.

Lowermost stick 1 of a multi-stack stick
When the electronic component 11 in 0 is lost and the pusher 12 reaches the position of the component supply unit 27, the sliding block 28 moves in the direction of arrow H to close the stick-side opening of the component supply unit 27. In this state, high-pressure air is sent from the air supply port 29, and the pusher 12 is driven by air pressure in the direction of arrow H, and is returned to the original cylinder 23. The movement of the sliding block 28 can be realized by various configurations. For example, as in this embodiment, a connecting member 36 connected to the sliding block 28 is connected to a drive shaft 37 of an air cylinder 38, The drive block 37 may be driven in the direction of arrow H to move the slide block 28.

When the pusher 12 is returned into the cylinder 23, the ejection levers 41 and 42 operate to eject the empty stick 10. That is, the discharge lever 4
₁ and 42 are mounted on horizontal support plates 45 and 56 so as to be rotatable around rotation shafts 43 and 44, respectively, and the discharge levers 41 and 42 are rotated in the directions of arrows C ₁ and C ₂ , respectively. As a result, the pressing portions 41a and 42a of the discharge levers 41 and 42 press the lowermost stick 10 in the direction of arrow F, and the stick 10 is dropped and discharged as shown by arrow G. Each ejection lever 41 in this ejection state,
The position of 42 is shown in FIG.

Arms 51, 52 as shown in FIGS. 1 to 3 are attached to the base 31 and the vertical plate 32, and these arms 51, 52 are attached to the discharged empty stick 10. It is received and accumulated (stocked).

By the way, although various configurations are conceivable for the rotation mechanism of each of the discharge levers 41 and 42, in this embodiment, as shown in FIG. 7, an air cylinder (not shown) is used.
A link mechanism using a disk 54 that is driven to rotate by the above-described method is adopted. That is, the disk 54 is supported on a horizontal support plate 56 so as to be rotatable around a rotation shaft 55, and the disk 54 is provided with a link plate 47 via a rotation pin 57.
However, a link plate 48 is attached via a pivot pin 58, respectively. These link plates 47, 48
Are connected to the discharge levers 41 and 42, respectively, and when the disk 54 rotates in the direction of arrow D, the link plate 4
Each discharge lever 41 and each arrow C ₁ direction by 7,48, is driven to rotate in the C ₂ direction, the ejection lever 4
1 and 42, each pressing part 41a, 42a is an empty stick 1.
0 is pressed and dropped into a storage section (stock section) composed of the arms 51 and 52 to be stored.

Here, the sliding plate 33 to which the horizontal support plate 34 for supporting the cylinder 23 is attached can be moved in the direction of arrow E, and the sliding plate 33 is interlocked with an air cylinder for driving the disk 54, for example. At the time of the stick discharging operation, the cylinder 23 may be moved backward, that is, the cylinder 23 may be retracted simultaneously with the empty stick discharging operation, so that the discharging operation of the stick 10 may be facilitated.

When the empty stick ejection operation is completed, the disk 54 is driven to rotate in the direction opposite to the arrow D, and the next stick 10 is guided by the stick guides 21 and 22 to drop to the lowermost position. Cylinders 23, 26,
The positioning between the stick guides 21 and 22 and the stick 10 is performed. In the case where the cylinder 23 has a sliding mechanism, after the stick falls, the cylinder 23 moves forward together with the rotation of the disk 54 to regulate the outer periphery and the bottom surface of the stick 10 as shown in FIGS. 5 and 6, for example. In addition, the end face is closed to prevent air leakage, and at the same time facilitate the pusher 12 to enter the stick 10.

When the positioning is performed, the air cylinder 38 operates to operate the sliding block 28 as the stopper.
Moves in the direction opposite to the arrow H, the component supply unit 27 is opened, and the component can be taken out by the chuck unit or the like of the component insertion device. Next, the air supply port 2 of the cylinder 34
4, high-pressure air is sent in, and the pusher 12 is driven by air pressure to sequentially press and move the electronic components 11 to supply components.

According to such an embodiment of the present invention, the pusher 12 moves inside the cylinder 26 connected to the stick 10.
The electronic component 11 can be conveyed to a predetermined position of the component supply unit 27 by pressing and sending the electronic component 11, and component supply can be performed without using a conventional mechanism for chucking a tilted electronic component or a component rotating mechanism. In addition, since the feeding of the electronic component is driven by the air pressure, the feeding is more reliable and the reliability of the component supply is improved as compared with the electronic component supply device using the own weight of the component. Further, since the feed mechanism is simplified, it is possible to change the type of the electronic component by changing the component with little adaptation and the like, which is excellent in versatility.

The present invention is not limited to the above embodiment. For example, an IC (integrated circuit) component is exemplified as an electronic component, but the electronic component can be arranged and packed in the stick (hollow container). Any electronic component can be used. Also, the shape of the stick 10 and the shape of the pusher 12 are not limited to the illustrated example, and the pusher rod 13 is also a round bar in the illustrated example. Of course, it may be formed in any shape such as
