In the belt feeding mechanism 17, the movable end of the drive lever 18 is pulled toward the front against the urging force of the coil spring 19, so that the driven plate 20 is moved in the clockwise direction in the figure through the link 21. The claw 22 can be angularly rotated, and the claw 22 can be moved from the currently engaged groove 24a to the adjacent groove 24a to be engaged (see the double-dotted chain line arrow in FIG. 6) in the course of rotation, and the claw 22 can also be driven. By releasing the pulling-in of the lever 18, the driven plate 20 is rotated and returned in the counterclockwise direction in the drawing by the urging force of the coil spring 19, and the ratchet wheel 24 engaging with the pawl 22 is moved in the same direction as the front pulley 15. By rotating the belt 14 by the same angle, the belt 14 can be moved forward by a predetermined pitch. By the way, in the illustrated example, the belt movement amount by one lever operation is set to be larger than the component length L.

Reference numeral 27 is a stopper, one end of which is rotatably attached to the front end of the component guide 12 by a pin 27a as shown in FIG. 7, and is biased counterclockwise in the drawing by a winding spring 28. Has been done. Further, the guide groove 12 is provided on the side surface of the stopper 27 on the component guide 12 side.

In the permanent magnet 29, one of the N pole and the S pole faces the front end of the guide groove 12a, and the magnetic force concentrated portion coincides with the center of the guide groove 12a. A return plate 32, which will be described later, is separated from the stopper 27 (see FIG. 10).

2, a first coil spring 33 that is stretched between the return plate 32 and the belt guide 13 and biases the return plate 32 forward, and is rotatably attached to the front portion of the component guide 12 by a pin 34a. The component holding lever 34,
Second for urging the component holding lever 34 in the clockwise direction in the figure
Coil spring 35, a component holding pin 36 inserted through a hole 12c provided in the front side surface of the guide groove 12a, and a third coil spring 37 for urging the component holding pin 36 outward. There is. In the illustrated state in which the return plate 32 is in the front position, the component holding lever 34 moves the second coil spring 35.
The component holding pin 36 is pushed into the guide groove 12a against the urging force of the third coil spring 37 by the biasing force in the clockwise direction in the figure, and the second component Pb is pushed by the component holding pin 36. It is pressed against the inner surface of the guide groove 12a and held at the same position. In addition, the return plate 32
The stopper 27 is opened forward by pressing
The leading part Pa moves forward while being attracted to the permanent magnet 29 of the stopper 27, and is completely separated from the second part Pb.

In the stopper release mechanism 30, the pawl wheel 31 is returned in the process of rotating and returning integrally with the pawl wheel 24 of the belt feeding mechanism 17 described above (the process of moving the belt 14 forward by a predetermined pitch). The claw portion 32b of the plate 32 can be moved from the currently engaged groove 31a to the adjacent groove 31a to move the return plate 32 backward by the height of the mountain (see the three-dot chain line arrow in FIG. 6). . When the return plate 32 moves rearward, as shown in FIG. 10, the stopper 27 comes into contact with the front end of the guide groove 12a by the urging force of the winding spring 28, and the protruding portion 34b of the component holding lever 34 moves. When pushed inward, the component holding lever 34 rotates counterclockwise in the figure against the biasing force of the second coil spring 35. This allows
The pressure from the component holding lever 34 to the component holding pin 36 is released, and the component holding pin 36 moves to the third coil spring 37.
The second component Pb is released from the holding state by being moved outward by the urging force of.

Here, the operation of taking in components to the fixed pipe in the above-mentioned chip component supplying apparatus will be described with reference to FIGS.
This will be described with reference to (d).

The drive lever 8 of the pipe up-and-down moving mechanism 7 and the drive lever 18 of the belt feeding mechanism 17 are used to remove a part of the head when the suction head descends toward the outlet 12b of the component guide 12 when the component is removed. It is pressed in synchronization with other power equipment.

The movable pipe 6 is in the lowered position as shown in FIG. 8 (a).
In this state, the chip parts P in the storage chamber 4a are stacked on the fixed pipe 5 and the movable pipe 6, and the movable pipe 6
Some chip parts P are also inserted in the annular pocket E formed above.

In the process in which the movable pipe 6 rises from the lowered position to the raised position, the upper pipe chip P is unraveled by the movable pipe 6 and the chip pipe lying on the fixed pipe 5 as shown in FIG. 8B. P is also pushed away from the same position. In the state of the movable pipe 6 in the raised position in the same figure (b), a bridge phenomenon may occur in the chip part P on the movable pipe 6, but as shown in the same figure (c), the movable pipe 6 is in the raised position. This can be broken by pushing up the fixed pipe 5 when descending from.

The components are taken into the fixed pipe 5 both during the ascending process and the descending process of the movable pipe 6, and the chip component P in the storage chamber 4a is lengthened by utilizing the inclination of the guide surface 6a of the movable pipe 6. It is sequentially taken into the fixed pipe 5 in the direction.

Since the movable pipe 6 is moved up and down from a lower position lower than that of the fixed pipe 5 and is moved up and down as one cycle, even if the chip component P enters the movable pipe 6, the chip part P will be moved up and down. Part P
Does not get stuck in the movable pipe 6. Moreover,
When the movable pipe 6 is in the lowered position, the movable pipe 6
Since the upper end of the movable pipe 6 is lower than the upper end of the sliding hole 4c and the upper end of the fixed pipe 5 so that the annular pocket E is formed on the movable pipe 6, the whole part is lowered when the movable pipe 6 descends. Even if the component density on the fixed pipe 5 becomes high, the movement of the movable pipe 6 is reduced by using the annular pocket E, which tends to make the component density rough, when the movable pipe 6 is lifted from the lowered position. Can be smoothly carried out, the problem that the movable pipe 6 cannot be lifted from the lowered position can be surely avoided, and the parts can be properly taken into the fixed pipe 5.

Next, the component discharging operation onto the belt in the above-described chip component supplying apparatus will be described with reference to FIGS. 9 (a) to 9 (c).

As shown in FIG. 9 (a), the chip component P taken into the fixed pipe 5 moves by its own weight in the discharge passage including the fixed pipe 5 in its longitudinal direction to reach the lowest position in the discharge passage. The tip part of the chip component P contacts the upper surface of the belt 14.

Since the belt 14 moves forward by a predetermined pitch in synchronism with the vertical movement of the movable pipe 6, the lowest chip component P contacting the belt 14 is, as shown in FIG. The contact end is pushed forward by the belt 14 that moves forward and tilts, and then lies on the belt 14. Since the weight of the uppermost chip component P is applied to the lowermost chip component P, it is possible to roll over sufficiently just by pressing the contact end portion with the belt 14 forward. Even when the chip component P moves forward without being tilted by the pressure applied by the belt 14, the corner portion on the front side of the boundary between the guide groove 12a of the component guide 12 and the discharge passage contacts the upper portion of the lowest chip component P on the transport side. Since they come into contact with each other, the above-mentioned rollover action can be surely performed without a mistake. The chip component P lying on the belt 14 moves forward together with the belt 14 in the longitudinal direction while being aligned by the guide groove 12a. Since the intermittent feeding of the belt 14 is repeated every time the leading chip component on the belt 14 is taken out, the lowest chip component P in the discharge passage is obtained.
Are discharged onto the belt 14 while being sequentially rolled (see FIG. 9C).

Since the fixed pipe 5 is arranged in a direction substantially perpendicular to the upper surface of the belt 14, the chip component P taken into the fixed pipe 5 is moved by the belt 1 by its own weight.
Up to 4 can be moved reliably and smoothly without resistance. Further, since the lowest chip component P in the discharge passage is laterally discharged using the belt movement and discharged onto the belt 14, the discharge passage can be changed in direction as compared with the case where the direction is changed by the inclination of the discharge passage itself. It is possible to shorten the length, and thus, the arrangement interval between the hopper 4 and the belt 14 can be configured to be small and the device can be downsized.

Next, the separating operation of the leading parts in the above-mentioned chip part supplying apparatus will be described with reference to FIGS. 10 and 7 (b).

Return plate 32 of stopper opening mechanism 30
The belt 14 is driven by the belt feeding mechanism 17 described above.
Moves backward in the initial process of moving forward by a predetermined pitch. When the return plate 32 moves rearward, as shown in FIG.
As shown in 0, the stopper 27 contacts the front end of the guide groove 12a by the urging force of the coil spring 28, and the projecting portion 34b of the component holding lever 34 is pushed inward, so that the component holding lever 34 moves to the second position. It rotates counterclockwise in the figure against the biasing force of the coil spring 35. This allows
The pressure from the component holding lever 34 to the component holding pin 36 is released, and the component holding pin 36 moves to the third coil spring 37.
Is moved outward by the urging force of the second component Pb to release the second component Pb, and the chip component on the belt 14
Along with this, when the leading part Pa comes into contact with the permanent magnet 29 of the stopper 27, the entire part stops moving.

When the belt movement of the predetermined pitch is completed, the return plate 32 of the stopper opening mechanism 30 is moved forward by the urging force of the first coil spring 33. When the return plate 32 moves forward, as shown in FIG. 7B, the pressure from the return plate 32 to the component holding lever 34 is released, and the component holding lever 34 is attached with the second coil spring 35. The force returns to the clockwise direction in the drawing to return the component holding pin 36 to the third coil spring 3.
7 is pushed into the guide groove 12a against the urging force of the guide member 7 and the second component Pb is moved to the guide groove 12a by the component holding pin 36.
It is pressed against the inner surface of a and held at the same position. Also,
The stopper 27 is opened forward by the pressing of the return plate 32, and the leading part Pa moves forward while being attracted to the permanent magnet 29 of the stopper 27 and is completely separated from the second part Pb.

The chip parts on the belt 14 are
When moving forward, the stopper 27 can be brought into contact with the front end of the guide groove 12a to stop the leading part Pa at a predetermined position, and when the leading part Pa comes into contact with the stopper 27 and movement of the entire component is stopped, 2 Th part P
While holding b at the same position, the stopper 27 is opened forward and the leading part Pa is moved forward while being attracted by the permanent magnet 29 of the stopper 27 to forcibly form a gap with the second part Pb. Therefore, the leading part Pa and the second part Pb stick to each other due to the influence of moisture or the processing liquid used in the part manufacturing stage, or the leading part Pa and the second part Pb are caught by mutual surface irregularities. Even if there is, the leading part Pa is reliably separated from the second part Pb to prevent the second part Pb from being fished and disturbed in position and attitude, and to favorably remove the leading part Pa by the suction head or the like. It can be carried out.

The leading component Pa on the belt 14 is sequentially taken out from the belt 14 by a suction head of a component mounter or the like and transferred to a circuit component such as a printed circuit board. As described above, since the leading part Pa is completely separated from the second part Pb every time it is stopped by the stopper 27, the leading part Pa can be taken out very smoothly.
As a result, it is possible to perform good component transfer to a circuit component such as a printed circuit board at high speed.

In addition to the above, the above-described chip component supply device can obtain the following actions and effects.

That is, even when an excessive pressing force is applied from the suction head or the like to the leading part Pa when the leading part Pa on the belt 14 is taken out by the suction head or the like, the elasticity of the belt 14 itself exerts the pressing force. Can be absorbed by. Further, since the belt guide 13 is extended to the lower side of the take-out port 12b of the component guide 12, even if a pressing force is applied at the time of taking out the component, there is no fear that the leading component Pa dives more than necessary.

Further, even if an error occurs in taking out the leading part Pa, only the belt 14 is moved while the entire components on the belt 14 are stopped by the stopper 27 at the time of the next component transportation, and the leading part Pa pops out. Posture disturbance can be prevented. Moreover, since the feeding pitch of the belt 14 is set to be larger than the length L of the chip component, even when the component discharge from the fixed pipe 5 onto the belt 14 is temporarily delayed and a gap is generated between the components, The gap can be clogged and eliminated by subsequent belt movement.

Further, as shown in FIG. 11, the stopper 2
7 is pushed open with a fingertip, and the protruding portion 34b of the component holding lever 34 is pushed inward with a fingertip to push the component holding pin 36.
If the holding of the second component Pb by the above is released, a large number of chip components P in the guide groove 12a of the component guide 12 can be dropped from the front end of the guide groove 12a by their own weight and extracted, so that the chip components to be supplied are supplied. Even when changing the type, etc., the replacement work can be performed very easily.

Modifications of the above-described chip component supply apparatus will be described below with reference to FIGS. 12 to 33 in order. In each modification, the same reference numerals are used for the parts having the same configurations as those shown in FIG. 1, and the description thereof will be omitted.

The movable pipe 44 shown in FIG.
A plurality of grooves 44b (three at regular intervals in the drawing) having a width smaller than the width of the chip component are formed on the guide surface 44a inclined toward the center. According to the movable pipe 44, the chip component on the guide surface 44a is destabilized by the groove 44b, and the probability that the chip component is taken into the movable pipe 44 can be increased.

The movable pipe 45 shown in FIG.
The inclined guide surfaces 45a having an angle of about 90 degrees when viewed from above are provided so as to face each other by 180 degrees. Similarly to the above, the movable pipe 46 shown in FIG. 12 (f) has inclined guide surfaces 46a having an angle of about 90 degrees in a direction facing each other by 180 degrees as viewed from above, and a rectangular fixed pipe can be inserted therethrough. Inner hole 46 of rectangular cross section
b. These movable pipes 45 and 46 are effective when a flat prismatic chip component (see FIG. 5C) is to be supplied, and the chip component has a lateral surface in the longitudinal direction in which it contacts the guide faces 45a and 46a. In this state, the chip components that are taken into the movable pipes 45 and 46, and are in the other orientations or positions that deviate from the guide surfaces 45a and 46a fall from the guide surfaces 45a and 46a and fall into the movable pipes 45 and 46.
Is not taken into. In addition, the guide surfaces 45a and 46a described above.
May be smaller than 90 degrees and is also shown in FIG.

[0105]

As described above in detail, according to the chip component supply device of the present invention, the leading part and the second part are attached to each other due to the influence of moisture or the processing liquid used in the part manufacturing stage, Alternatively, even if the leading part and the second part are caught by mutual surface irregularities,
It is possible to reliably separate the first part from the second part, prevent the second part from being caught, and disturb the position and posture, and thus it is possible to favorably take out the first part by the suction head or the like.

[0106]

Further, since the lowest chip component in the discharge passage can be horizontally rolled and discharged onto the belt by utilizing the belt movement, the discharge passage is shortened as compared with the case where the direction is changed by the inclination of the discharge passage itself. As a result, the arrangement distance between the hopper and the belt can be reduced, and the device can be downsized.
