SOLUTION: Many prismatic chip components P are stored in a hopper, and supplied to a component guide 5 via a fixed pipe 3 which is provided on the bottom of the hopper and whose inner shape is rectangular. The guide 5 has a curved passage 5a and a horizontal passage 5b, the passage 5a communicating with the lower end of the pipe 3, and is attached to the upper surface of a belt guide 7. The circumferential edge 6a of a rotatable disc 6 is provided on the inner wall of the passage 5a so as to extend over the range of 90 deg.. Although a component P that has entered into the passage 5a from the pipe 3 moves along the passage 5a by its own weight in accordance with the curvature, when the passage 5a is blocked due to the component P having been inclined therein during movement, the disc 6 is rotated forward and backward, thereby rectifying the posture of the component P to rid the component P of its being caught, and hence allowing the component P to be transferred satisfactorily.

It is detachably attached to the frame 1 so as to cover the lower surface of the component guide 6. The center in the width direction of the linear groove 7a substantially coincides with the center in the width direction of the lateral passage 5b of the component guide 5.

The belt 8 is shown in FIGS. 1, 5, 6, and 8
As shown in (A), it is made of a flexible and non-magnetic endless timing belt or endless flat belt made of synthetic rubber, soft resin or the like. The belt 8 is wound around a pair of pulleys 9 rotatably supported on the frame 1 at a predetermined position at front and rear positions of the belt guide 7, and the upper flat portion is inserted into the linear groove 7 a of the belt guide 7. The surface of this part is in contact with the lower surface of the component guide 6 in a movable state. Although not shown, a ratchet mechanism for intermittently rotating the pulley 9 in a counterclockwise direction by a predetermined angle is connected to the front pulley 9.
By the operation of the ratchet mechanism, the upper flat portion of the belt 8 intermittently moves forward by a predetermined distance.

The component stopper 10 is shown in FIG. 1 and FIG.
As shown in FIG.
Oa is rotatably supported on one side of the upper surface of the front part of the belt guide 7. Also, the lateral passage 5 of the component stopper 10
A rectangular parallelepiped rare-earth permanent magnet 10b is embedded in a portion facing the front end of b. This component stopper 10 is moved by a coil spring S2 provided at the pin location as shown in FIG.
(A) is biased in the counterclockwise direction, and is displaced to the component removal position while being pressed by the stopper driving plate R that reciprocates in synchronization with the operation of the ratchet mechanism. Incidentally, the component stopper 10 is displaced to the component stop position by contacting the magnet side surface with the front end of the component guide 5 in a state where the pressing from the stopper driving plate R is released (see FIG. 8B).

The pipe driving lever 11 has its central portion rotatably supported below the hopper 2 of the frame 1 via a pin 11a. Also, the pipe driving lever 11

When the chip component P is taken out of the apparatus by a suction nozzle (not shown), the end of the pipe driving lever 11 is moved downward by a part interlocked with the suction nozzle or another driving device as shown by a white arrow in FIG. Is pressed.

When the end of the pipe driving lever 11 is pressed downward and the pipe driving lever 11 rotates a predetermined angle counterclockwise about the pin 11a, the engagement moves upward as shown in FIG. Movable pipe 4 by the part 11b
Rises against the urging force of the coil spring S1. When the downward pressing of the end of the pipe driving lever 11 is stopped, the engaging portion 11b moves downward by the urging force of the coil spring S1, the pipe driving lever 11 returns to the rotation, and the movable pipe 4 moves down from the raised position. It returns and returns to the state of FIG.

In both the process of moving the movable pipe 4 from the lowering position and the process of lowering from the raising position, the tip component P on the upper side of the pipe is moved up and down to be agitated, and the storage component P is guided by the guide surface 4a. While moving, it moves downward by its own weight and is taken into the movable pipe 4, and is taken one by one into the upper end opening of the fixed pipe 3 in the longitudinal direction. Of course, the storage component P may be directly taken into the upper end opening of the fixed pipe 3 without being guided by the guide surface 4a.

The chip component P taken into the fixed pipe 3 by the raising / lowering operation of the movable pipe 4 moves downward in the fixed pipe 3 by its own weight, and is aligned from the fixed pipe 3 into the curved passage 5 a of the component guide 5. Get in. The chip component P that has entered the curved passage 5a moves by its own weight in the passage 5a according to the curvature thereof, and is discharged from the surface of the belt 8 after being changed from vertical to horizontal by about 90 degrees as shown in FIG.

On the other hand, when the end of the pipe driving lever 11 is pressed downward, the ratchet mechanism (not shown) also operates, the front pulley 9 rotates counterclockwise by a predetermined angle, and the belt 8 rotates. It moves forward by a distance corresponding to the corner, preferably a distance larger than the length dimension L of the chip component P.

In the process in which the belt 8 moves forward by a predetermined distance, the chip components P discharged from the curved passage 5a to the surface of the belt 8 move forward by the same distance together with the belt 8.
Since the intermittent movement of the belt 8 is repeated every time the chip component P is taken out of the apparatus, the chip components P connected in the curved passage 5a are sequentially discharged to the belt surface, and are aligned in the longitudinal direction while being aligned by the lateral passage 5b. Are transported forward in a line.

On the other hand, when the ratchet mechanism (not shown) operates to move the belt 8 forward by a predetermined distance, the stopper driving plate R moves backward from the standby state shown in FIG. Move forward from the state and return.

In the process of the stopper driving plate R moving backward from the standby state of FIG. 8A, as shown in FIG.
Component stopper 1 released from pressing from stopper driving plate R
0 rotates counterclockwise around the pin 10a by the urging force of the coil spring S2, and the magnet-side surface contacts the front end of the component guide 5 to be displaced to the component stop position. That is,
The chip component P conveyed forward by the belt movement is the first chip component P, which is the permanent magnet 1 of the component stopper 10.
Stop when it contacts 0b. When the forward movement amount of the belt 8 per one time is set to be larger than the length dimension of the chip component P, even after the leading chip component P abuts on the permanent magnet 10b, the forward movement amount of the belt 8 is not changed. Only the belt 8 is slightly advanced using the slip.

In the process in which the stopper driving plate R moves forward and returns from the state shown in FIG. 8B, as shown in FIG. 8A, the component stopper 10 is pressed by the stopper driving plate R to cause the coil spring S2 to move. Pin 10 against the urging force of
It rotates clockwise around a and is displaced to the component stop position. At this time, since the movement of the belt 8 is almost stopped, the leading chip component P, which is in contact with and attracted to the permanent magnet 10b, moves forward on the belt surface while maintaining the attracted state, and A gap G is forcibly formed between the first chip component P and the second chip component P apart from the component.

As shown in FIG. 8A, when picking up a component from the apparatus by the suction nozzle, the leading chip component P moves forward together with the component stopper 10 and completely separates from the second chip component P. Since the first chip component P does not interfere with the second chip component P,
Moreover, it can be taken out in a stable posture.

By the way, from the fixed pipe 3 to the component guide 5
The chip component P that has entered the curved passage 5a of the
a, the chip component P in the middle of movement is inclined as indicated by a reference symbol P1 in FIG. 9 or is shifted as indicated by a reference symbol P2 in relation to the clearance between the inner wall of the passage and the chip component P.
