The present invention will be explained in detail below with reference to FIGS. 2 and 3. FIG. 2 is an explanatory diagram of an embodiment according to the present invention, (a)
is a perspective view of the loading device, (b) is a perspective view of the supply device,
The figures are explanatory diagrams of the present invention, (a) is an explanatory diagram of the discrimination section, (b)
) is an explanatory diagram of the selector section, (C) is a perspective view of the front-back reversal section, and (d) is a sectional view taken along line AA in (c).

The same reference numerals indicate the same objects throughout the figures.

As shown in FIG. 2(b), a selector section 3 rotated by a rotary drive mechanism 3A is provided on a linear feeder IA through which parts 2 loaded into a linear vibration type hopper feeder 1 are delivered in a line, The front part 2 of the parts 2 selected by the selector unit 3 is transferred to the first supply station 8 via the first transfer path 4, and the back part 2 is transferred to the second transfer path equipped with the front-back reversing unit 6. 5 to the second supply station 9 by means of a head difference.

Therefore, as shown in (a), by arranging such first and second supply grooves 8 and 9 at the location where the component 2 is picked up by the suction rod 11, The second supply stations 8 and 9 will be positioned with the parts 2 lined up on the front side, and the suction head 11 will initially suck and hold the parts 2 from the first supply station 8 and mount them on the printed circuit board IO. The first and second supply stations 8 and 9 then suck and hold the component 2 from the second supply station 9 and mount it on the printed circuit board IO.
Continuous operation can be performed by alternately supplying parts 2 from 1 to 2.

Further, as shown in FIG. 3(a), the front and back sides of the component 2 are determined by irradiating the component 2 taken into the selector section 3 with the light Ll from the illumination 7B, and receiving the reflected light L2 by the camera 7A. , the image received by the camera 7A is sent to the front/back determination section 7, which analyzes the bright and dark parts of the image to determine whether it is front or back, and the front/back determination result is sent as a discrimination signal S.
The notification is sent by outputting to the rotational drive mechanism 3A.

This type of discrimination between front and back can be done using (bl) and (b) in Figure 4 mentioned above.
In the case of part 2 shown in 2), if part 2 is facing up, there will be fewer reflective parts, so there will be more dark parts in the image, and conversely, if part 2 is facing back, there will be more reflective parts, so there will be more dark parts in the image. There are many bright areas, which makes it easy to distinguish between the front and back sides.

Furthermore, as shown in (b), the selector part 3 is formed by providing a plurality of pockets 3C for storing one component 2 on a disc 3B rotated by a rotational drive mechanism 3A, and is formed by providing a plurality of pockets 3C for storing one component 2, as indicated by the arrow F. After the part 2 fed from the hopper feeder 1 is stored in the pocket 3C, if it is a front side, the disc 3B is rotated in the direction of the arrow Fl by the discrimination signal S, and the part 2 is moved from the PI position to the P2 disc 3B. The part 2 is rotated in the direction of the arrow F2, and as shown in (C), the part 2 transferred in the direction of the arrow F4 is turned face up and sent out in the direction of the arrow F5. It is configured as follows.

As shown in (d), this reversal is achieved by holding the part 2 facing down and placed in the upper part 6A by the partition 6C.
As the width of the partition 6C gradually narrows, the parts 2 are turned over as shown by arrow C, and the part 2 facing down is turned face up.

Therefore, the front part 2 can be positioned at the second supply station 9 in the same way as at the first supply station 8.
