Therefore, the first chip component P can be taken out in a stable posture without interfering with the second chip component P.

As described above, according to the apparatus of the first embodiment, the U-shaped groove 8a having a width and depth slightly larger than the width and height of the chip component P is formed in the center of the surface of the belt 8 in the belt length direction. Since the components can be conveyed in a state in which the chip components P are formed continuously and the chip components P are accommodated in the grooves 8a in a lateral orientation, the chip components P being conveyed can be reliably prevented from coming into contact with other components. The transfer can be performed favorably.

In the first embodiment, the belt groove 8
a, the chute portion 5b inserted and arranged in the first component guide 5 is formed integrally with the first component guide 5.

Mounted freely. The cross-sectional shape of the straight groove 32a is U-shaped, and its size substantially matches the cross-sectional shape of the curved passage 31a.

The belt 33 is a flexible, non-magnetic endless flat belt made of synthetic rubber, soft resin or the like.
Also, in the center of the back surface of the belt 33, FIGS.
As shown in the figure, a plurality of columnar rare earth permanent magnets M2 are embedded at equal intervals in the belt length direction. Each permanent magnet M2 is arranged such that one of its N and S poles (N pole in the figure) faces the belt surface side. The belt 33 is wound around the pair of pulleys 9 with a predetermined tension, and movably contacts the bottom surfaces of the first and second component guides 31 and 32.

The component stopper 34 is made of a plate-like member, and has a shaft support hole (not shown) at one end. A rectangular parallelepiped rare-earth permanent magnet M1 is embedded on the component-facing side of the component stopper 34. The component stopper 34 has its shaft support hole rotatably mounted on the pin 7b of the belt guide 7, and is urged in a counterclockwise direction viewed from above by a coil spring S3 interposed between the pin stopper 7b and the pin 7b. The end (free end) is in contact with the stopper drive plate 19.

When the forward movement amount of the belt 33 per one time is formed to be larger than the length dimension of the chip component P, even after the leading chip component P abuts on the permanent magnet M1, the contact with the chip component P can be maintained. Only the belt 33 advances slightly using the slip.

When the stopper driving plate 19 returns to the front, the component stopper 10 turns forward around the pin 7b against the urging force of the coil spring S3 and returns to the standby state. In other words, as shown in FIG. 17, the leading chip component P that is in contact with and attracted to the permanent magnet M1 moves forward on the belt surface while maintaining the attracted state, separates from the subsequent chip component, and moves to the leading chip component. A gap G is forcibly formed between the chip component P and the second chip component P.

As shown in FIG. 17, when picking up components from the apparatus by the suction nozzle, the first chip component P moves forward together with the component stopper 34 and the second chip component P
