[0023]
In the belt feeding mechanism 17 described above, the movable end of the drive lever 18 is pulled forward against the urging force of the coil spring 19 so that the driven plate 20 is rotated by a predetermined angle in the clockwise direction in FIG. In the turning process, the claw 22 can be moved from the currently engaged groove 24a to the adjacent groove 24a (see the two-dot chain line arrow in FIG. 6). By releasing the pull-in, the driven plate 20 is rotated back in the counterclockwise direction in the figure by the biasing force of the coil spring 19, and the claw wheel 24 engaged with the claw 22 is moved together with the front pulley 15 by the same angle in the same direction. By rotating, the belt 14 can be moved forward by a predetermined pitch. Incidentally, in the illustrated example, the amount of belt movement by one lever operation is set larger than the component length L.
[0024]
Reference numeral 27 denotes a stopper. As shown in FIG. 7, one end of the stopper 27 is rotatably attached to the front end of the component guide 12 by a pin 27a, and is urged counterclockwise by a winding spring 28 in the figure. .

The second component Pb is pressed against the inner surface of the guide groove 12a by the component holding pin 36 and held in the same position. Further, 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.
[0026]
In the stopper opening mechanism 30 described above, the hooking wheel 31 is rotated and returned integrally with the hooking wheel 24 of the belt feeding mechanism 17 described above (the belt 14 moves forward by a predetermined pitch). The claw portion 32b can be moved from the currently engaged groove 31a to the adjacent groove 31a, and the return plate 32 can be moved 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 abuts against 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 When pushed inward, the component holding lever 34 rotates counterclockwise in the figure against the urging force of the second coil spring 35. As a result, the pressing from the component holding lever 34 to the component holding pin 36 is released, the component holding pin 36 moves outward by the biasing force of the third coil spring 37, and the holding of the second component Pb is released. Is done.
[0027]
Here, the component taking-in operation to the fixed pipe in the above-described chip component supply apparatus will be described with reference to FIGS.
[0028]
The drive lever 8 of the pipe vertical movement mechanism 7 and the drive lever 18 of the belt feed mechanism 17 are configured so that a part of the head or other power is applied when the suction head descends toward the take-out port 12b of the component guide 12 when the component is taken out. The pressing operation is synchronized with the device.
[0029]
In the state of FIG. 8A in which the movable pipe 6 is in the lowered position, the chip parts P in the storage chamber 4 a are stacked on the fixed pipe 5 and the movable pipe 6, and are formed on the movable pipe 6. Some chip parts P also enter the annular pocket E.
[0030]
In the process of moving the movable pipe 6 from the lowered position to the raised position, as shown in FIG. 8B, the upper chip part P is unwound by the movable pipe 6, and the chip part P lying on the fixed pipe 5 is also the same. Pushed away from position. In the state shown in FIG. 5B where the movable pipe 6 is in the raised position, a bridging phenomenon may occur in the chip part P on the movable pipe 6. However, as shown in FIG. This can be broken down by pushing up the fixed pipe 5 when descending.
[0031]
The parts are taken into the fixed pipe 5 in both the ascending process and the descending process of the movable pipe 6, and the chip part P in the storage chamber 4 a is fixed in the longitudinal direction using the inclination of the guide surface 6 a of the movable pipe 6. It is sequentially taken into the pipe 5.
[0032]
The movable pipe 6 is moved up and down from a lower position lower than the fixed pipe 5 and moved up and down from the raised position as one cycle. Therefore, even if the chip part P enters the movable pipe 6, the chip part P is not moved. There is no clogging in the movable pipe 6. Moreover, when the movable pipe 6 is in the lowered position, the upper end of the movable pipe 6 is made lower than the upper end of the sliding hole 4c and the upper end of the fixed pipe 5 so that an annular pocket E is formed on the movable pipe 6. Therefore, even when the whole part is lowered and the part density on the fixed pipe 5 is increased when the movable pipe 6 is lowered, the movable pipe 6 is lowered by using the annular pocket E in which the part density tends to be coarse. The rise start resistance when rising from the position can be reduced and the movement can be performed smoothly, and the problem that the movable pipe 6 cannot rise from the lowered position is surely avoided, and the parts are taken into the fixed pipe 5. Can be performed satisfactorily.
[0033]
Next, the component discharging operation onto the belt in the above-described chip component supply apparatus will be described with reference to FIGS.
[0034]
As shown in FIG. 9A, the chip component P taken into the fixed pipe 5 moves by its own weight in the discharge passage including the fixed pipe 5 while being in the longitudinal direction, and the lowest chip component in the discharge passage. P abuts against the upper surface of the belt 14 at its end.
[0035]
Since the belt 14 moves forward by a predetermined pitch in synchronism with the vertical movement of the movable pipe 6 described above, the lowermost chip component P contacting the belt 14 moves forward as shown in FIG. The contact end portion is pushed forward by the belt 14 and tilts, and eventually lies on the belt 14. Since the weight of the upper chip part P is applied to the lowermost chip part P, it is possible to roll over sufficiently only by pressing the contact end with the belt 14 forward. Even when the chip part P moves forward without being tilted by the pressure applied by the belt 14, the corner part on the front side of the boundary part between the guide groove 12a of the part guide 12 and the discharge passage is in contact with the upper part on the conveyance side of the lowermost chip part P. Therefore, the above rollover action is surely performed without a mistake. The chip component P lying on the belt 14 moves forward together with the belt 14 while maintaining the longitudinal direction while receiving an alignment action by the guide groove 12a. Since the intermittent feeding of the belt 14 is repeated every time the first chip part on the belt 14 is taken out, the lowest chip part P in the discharge passage is discharged onto the belt 14 while being subjected to a rollover action in sequence (FIG. 9). (See (c)).
[0036]
Since the fixed pipe 5 is arranged at a substantially right angle with respect to the upper surface of the belt 14, the chip component P taken in the fixed pipe 5 can be moved to the belt 14 surely and smoothly without resistance by its own weight. Can do. Further, since the lowest chip part P in the discharge passage is rolled over by belt movement and discharged onto the belt 14, the discharge passage is less than in the case where the direction is changed by the inclination of the discharge passage itself. Accordingly, the arrangement distance between the hopper 4 and the belt 14 can be reduced, and the apparatus can be downsized.
[0037]
Next, the separation operation of the leading component in the above-described chip component supply apparatus will be described with reference to FIGS. 10 and 7B.
[0038]
The return plate 32 of the stopper opening mechanism 30 moves backward in the initial process in which the belt 14 moves forward by a predetermined pitch by the belt feeding mechanism 17 described above. When the return plate 32 moves rearward, as shown in FIG. 10, the stopper 27 abuts against 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 is pushed inward. Accordingly, the component holding lever 34 rotates counterclockwise in the drawing against the urging force of the second coil spring 35. As a result, the pressing from the component holding lever 34 to the component holding pin 36 is released, the component holding pin 36 moves outward by the biasing force of the third coil spring 37, and the holding of the second component Pb is released. Then, the chip part on the belt 14 moves forward together with the belt 14, and the movement of the whole part stops when the leading part Pa abuts on the permanent magnet 29 of the stopper 27.
[0039]
When the belt movement at a predetermined pitch is completed, the return plate 32 of the stopper opening mechanism 30 is moved forward and returned 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 to 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 force, so that the component holding pin 36 is pushed second by the component holding pin 36. The component Pb is pressed against the inner surface of the guide groove 12a and held at the same position. Further, the stopper 27 is released forward by the pressing of the return plate 32, 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.
[0040]
When the chip part on the belt 14 moves forward together with the belt 14, the leading part Pa can be stopped at a predetermined position by bringing the stopper 27 into contact with the front end of the guide groove 12a, and the leading part Pa is brought into contact with the stopper 27. When the movement of the entire part stops, the second part Pb is held in 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. Since a gap is forcibly formed between the part Pb and the leading part Pa and the second part Pb are stuck to each other under the influence of moisture, a processing liquid used in the part manufacturing stage, or the leading part Pa. Even if the second part Pb is caught by surface irregularities, the leading part Pa is surely separated from the second part Pb and the second part Pb is pulled. The removal of the top part Pa by preventing disturbance of fished been or position and attitude suction head or the like can be performed well.
[0041]
The leading component Pa on the belt 14 is sequentially taken out from the belt 14 by a suction head or the like of a component mounting machine and transferred to a circuit component such as a printed board. As described above, the leading part Pa is completely separated from the second part Pb every time it is stopped by the stopper 27, so that the leading part Pa can be taken out very smoothly. Good parts can be transferred at high speed to the components.
[0042]
In addition to the above, the above-described chip component supply apparatus has the following operations and effects.
[0043]
That is, even when an excessive pressing force is applied to the leading part Pa from the suction head or the like when the leading part Pa on the belt 14 is taken out by the suction head or the like, the pressing force is absorbed by the elasticity of the belt 14 itself. be able to. Further, since the belt guide 13 is extended to the lower side of the outlet 12b of the part guide 12, there is no fear that the leading part Pa will be unnecessarily submerged even if a pressing force is applied when the part is taken out.
[0044]
Further, even if an error occurs in taking out the leading part Pa, when the next part is conveyed, only the belt 14 is moved while the whole part on the belt 14 is stopped by the stopper 27 so that the leading part Pa is ejected or the posture is disturbed. Can be prevented. Moreover, since the feed 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, Subsequent belt movement can eliminate the gap.
[0045]
Further, as shown in FIG. 11, if the stopper 27 is pushed open with the fingertip, and the protruding portion 34 b of the component holding lever 34 is pushed inward with the fingertip to release the holding of the second component Pb by the component holding pin 36, Since a large number of chip components P in the guide groove 12a of the component guide 12 can be removed by dropping their weight from the front end of the guide groove 12a, the replacement work can be performed even when the type of chip component to be supplied is changed. Very easy to do.
[0046]
Hereinafter, a modified example of the above-described chip component supply apparatus will be described with reference to FIGS. 12 to 33 in order. In addition, in each modification, the same code | symbol is used for the part which has the same structure as what was shown in FIG. 1, and the description is abbreviate | omitted.
[0047]
FIGS. 12A to 12H show modifications of the movable pipe. The movable pipe 41 shown in FIG. 12 (a) has a guide surface 41a at the upper end that is curved upward and inclined toward the center. The movable pipe 42 shown in FIG. 12B has a guide surface 42a at the upper end that is curved downward and inclined toward the center. The movable pipe 43 shown in FIG. 12C has a guide surface 43a at the upper end that has a stepped step and is inclined toward the center.
[0048]
The movable pipe 44 shown in FIG. 12 (d) is formed with a plurality of grooves 44b (three at equal intervals in the figure) having a width smaller than the width of the chip part on the guide surface 44a inclined toward the center. It is. According to this movable pipe 44, the chip component that rides on the guide surface 44a can be destabilized by the groove 44b, and the probability that the chip component is taken into the movable pipe 44 can be increased.
[0049]
The movable pipe 45 shown in FIG. 12 (e) has an inclined guide surface 45a having an angle of about 90 degrees as viewed from above in a direction opposite to the 180 degrees. The movable pipe 46 shown in FIG. 12 (f) has an inclined guide surface 46a having an angle of about 90 degrees as viewed from above in the same direction as above, and is capable of being inserted through a rectangular fixed pipe. The inner hole 46b has a rectangular cross section. 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 longitudinal direction in which the side surface in the width direction is in contact with the guide surfaces 45a and 46a. Only in this position, the chip parts are taken into the movable pipes 45 and 46, and chip components in other directions and positions away from the guide surfaces 45a and 46a fall from the guide surfaces 45a and 46a and are taken into the movable pipes 45 and 46. I can't. The guide surfaces 45a and 46a may be smaller than a 90 degree angle, or may be a single one (47a) such as the movable pipe 47 shown in FIG. Moreover, you may comprise said guide surfaces 45a and 46a from several inclination protrusion (48a) like the movable pipe 48 shown in FIG.12 (h).
[0050]
FIG. 13A shows a modified example of the movable pipe, more specifically, a structural example in which the movable pipe can be rotated in the vertical movement process. A spiral groove 49a is formed on the outer surface of the movable pipe 49, and a pin 50 that engages with the spiral groove 49a protrudes from the inner surface of the sliding hole of the hopper. According to this structure, as shown in FIG. 5B, when the movable pipe 49 is rotated up and down around the axis center in the process of raising and lowering the fixed pipe 5, the rise start resistance is increased by the rotation.
