The operation of the above configuration will be described below.

First, before the automatic operation of the component mounting device, the operator pulls the swing arm (60) of the bulk cassette feeder (8) by hand and sends it to the rotor (34).
The chip part (4) is stored in the chip separation station (35) and the groove (33) at the stop position rotated by 90 degrees from the station. In the first chute (25) and the second chute (26) of the cassette feeder (8), chip components (4) are continuously arranged from the second chamber (23) (24) side to the outlet side, respectively. ing. "0" is stored in the memory (88) in the RAM (86) in accordance with the state of the rotors (34) and (35). The initialization of the memory (88) may be performed by an operator from an operation unit (not shown) in accordance with the state of the rotors (34) and (35). Alternatively, “0” may be stored at the start of the operation.

When the automatic operation is started, the RAM (86)
CPU according to mounting data (not shown) stored in
(85) The tape feeder (7) or the bulk cassette feeder (8) for controlling the drive of the supply stand drive motor (10) and supplying the component (4) to be sucked next to the suction nozzle (14). It is moved along the linear guide (12) and stops at the component suction position.

The component (4) to be sucked next is supplied by the central feeder (8) of the three bulk cassette feeders (8) shown in FIG. ) Is as shown in FIG. 2, the CPU (8)

With the movement of the supply table (6), the intermittent rotation of the turntable (13) causes the next mounting head (15) to move to the suction station, but when the supply table (6) stops, the feed lever cam (66). 7), the feed swing lever (68) swings counterclockwise in FIG. 7 about the support shaft (67) as a fulcrum, and the feed lever (64) is urged by the tension spring (69) to push the feed lever (64) in FIG. Move to the left and swing arm (60)
Is swung to the left in FIG. 7 against the tension spring (63).

Then, the compression spring (59) moves the rack in FIG.
5 is moved along the guide roller (57) and the guide body (58) to the right side of FIG. 5, and the pinions (43) and (44) are moved.
Is rotated. The resulting ratchet bracket (46)
By the rotation of (47), the ratchets (51) and (52) rotate the ratchet wheels (48) and (49), respectively. At a position where the ratchet wheels (48) and (49) are rotated by 90 degrees, the rack (56) is stopped by a stopper (not shown), and the ratchet wheels (48) and (49) stop rotating. At this position, the ratchet lock pawl ( 53) (5
4) engage with the wheel grooves (50) of the ratchet wheels (48) and (49), respectively. Thus, the rotor shaft (40) on which the ratchet wheels (48) and (49) are respectively mounted.
When (41) rotates 90 degrees, the rotor (34) rotates clockwise in FIG. 3 and the rotor (35) rotates 90 degrees counterclockwise, and the grooves (4) for accommodating the respective parts (4) are received. 33)
Moves to the chip suction station, and the component (4) in the groove (33) slides on the component mounting surface (36) and moves to the station.

Next, when the feed lever (64) returns to the left side in FIG. 4, the swing arm (60) returns to the pinion (43).
(44) and the ratchets (51) and (52) also return to their original positions, but the ratchet wheels (48) and (49) are not rotated since they are locked by the ratchet lock claws (53) and (54), respectively. (34) and (35) hold the rotated position.

At this time, the chip parts (4) are stored in the grooves (33) in the respective chip separation stations of the rotors (34) and (35).

That is, the swinging of the swing arm (60) due to the rightward movement of the feed lever (64) in FIG. 1 causes the fitting pin (80) to reach the right end of the elongated hole (79). The lever (76) moves to the right in FIG. Then, the lever (77) swings about the support shaft (78), and the cam follower (81) moves the pin (75) to the left side in FIG. 1 against the compression spring (82). As a result, the ball (74) is pressed against the ball compression spring (73), separated from the ceiling (72), and the air passage (31) is opened.

Then, the parts (4) aligned in the chutes (25) and (26) are respectively discharged from the chute air supply holes (29) and (30) when the rotors (34) and (35) stop. Pressed by compressed air, leading part (4)
Are extruded and stored in the grooves (33) of the respective chip separation stations.

On the other hand, the chamber air supply holes (28) (2)
9), compressed air is simultaneously ejected from the chute air supply holes (29) and (30), and the second chamber (23) (2)
4) Blow off the chip components (4) stored in
When the feed lever (64) returns to the left in FIG. 1 and the swing arm (60) returns, the pin (75) returns to the right and the ball (74) comes into close contact with the seal ring (72) and the air passage (31). Is closed. Then each chamber (23)
The part (4) blown off in (24) falls, and a part of it enters each chute (25) (26). The parts (4) entering the chutes (25) and (26) and compressed air from the air supply holes (29) and (30) are supplied from the chute (25) and (26) inlets to the supply holes (2).
9) Since part (4) is missing between (30),
The chutes (25) and (26) slide down due to their own weight and are aligned with the chutes (25) and (26) to prepare for the discharge of compressed air when the next rotors (34) and (35) rotate.

The swing arm (60) and the lever (7
6) A chip part (4) composed of a lever (77), a cam follower (81), a pin (75), a ball (74), an air passage (31), etc. is shot (25) (26).
The mechanism for aligning the components inside constitutes a chip component supply means of the bulk cassette feeder (8) itself, which is a component supply device.

The rotor (35) is located at the component suction position.
Is located, the suction nozzle (14) sucks and picks up the chip part (4) from the rotor (35), and the CPU (85) stores "2" in the part pick-up memory (88). I do.

Next, a mounting head (15) having a nozzle (14) for sucking the component (4) at the suction station.
Moves to the next stop position due to the intermittent rotation of the turntable (13), and the next mounting head (15) moves to the suction station.

Next, when the type of the component (4) to be taken out next is supplied by the same bulk cassette feeder (8), the CPU (85) takes out the component corresponding to the feeder (8). When the memory (88) is read and "2" is stored, the motor (10) is driven so that the chip suction station of the rotor (34) of the feeder (8) stops at the component suction position. (6) is moved. That is, in the case of the present embodiment, the supply table (6) moves to the right in FIG. 2 by 8.5 mm and stops.

Further, the CPU (85) excites the plunger (70) via the interface (89) and the drive circuit (90) because the data in the part pick-up memory (88) is not "0", and (71) is moved to the left side of FIG. The plunger (70) is actuated because the rotation position of the feed lever cam (66) still pushes the feed lever (64) against the urging force of the tension spring (67) in FIG.
The engaging piece (71) restricts the swing lever (68) from rotating counterclockwise in FIG.

In this way, the chip suction station of the rotor (34) stops at the component suction position, and the rotation of the feed lever cam (66) causes the feed lever (64).
7, the feed lever (64) does not move and the rotors (34) and (35) do not rotate due to the restriction of the engagement piece (71). The ball (7
The air passage (31) is also closed by 4), and after the previous discharge of the compressed air, the air supply holes (29) and (30) are closed while falling in the chutes (25) and (26). Even if there is no part (4) that has not passed, there is no discharge of compressed air from the chute air supply holes (29) and (30).
It can pass through the chute air supply holes (29) and (30).

Thus, the suction nozzle (14) sucks and takes out the component (4) from the groove (33) of the chip suction station of the rotor (34), and the CPU (85) sends the current data of the component take-out memory (88). Is not "0", the memory (88) is reset to "0", the excitation of the plunger (70) is turned off, and the engagement piece (71) is returned to the right side in FIG. At this time, the feed lever cam (66) has rotated to the position for moving the feed lever (64) to the right in FIG. 7, and the feed lever (64) is held at this position.

Next, when the type of the component (4) to be taken out next is the one supplied by the same bulk cassette feeder (8), the CPU (85) reads out the memory (88) and reads "0". Is stored, the smaller one of the two rotors (34) and (35) is selected as the moving distance or "0", and the supply stand (6) is kept stopped. When the next mounting head (15) rotates to the suction station, the rotation of the feed lever cam (66) causes the feed lever (64) to move as shown in FIG.
And the swing arm (60) is swung to swing the rotors (34) and (35) in the same manner as described above, and the chip components (4) are inserted into the grooves (33) of the respective chip suction stations. ) Is supplied.

At this time, the air passage (31) is
4) is opened by being pressed by the pin (75),
Chute after the previous discharge of compressed air (25) (26)
Chute (25) including the parts (4) slid down within
The part (4) aligned in (26) is pressed against the outlet side of the chutes (25) and (26) by the discharge air discharged from the air supply holes (29) and (30), and the groove of the chip separation station is formed. The first part (4) is stored in (33). Also, the part (4) that has been accumulated near the inlets of the chutes (25) and (26) of the second chambers (23) and (24) is compressed by compressed air from the air supply holes (27) and (28) in the same manner as described above. Blown off.

Next, the suction nozzle (14) is connected to the rotor (3).
Suction the part (4) of the chip suction station of 4),
The CPU (85) stores “1” in the memory (88).

Next, when the type of the component (4) to be taken out next is to be supplied from another tape feeder (7), the supply table (6) causes the feeder (7) to pick up the component. The suction nozzle (14) of the mounting head (15), which moves to stop at the position, then sucks the component (4).

Next, when the type of the component (4) to be taken out next is that of the central feeder (8) of the bulk cassette feeder (8) in FIG. Since the memory (88) of (8) is read and "1" is stored instead of "0", the supply table (6) is moved so that the rotor (35) of the feeder (8) stops at the component suction position. Move.

Then, as described above, the plunger (70)
When the component (4) in the chip suction station of the rotor (35) is sucked by the suction nozzle (14) without rotating, the rotor (34) (35) is stored in the memory (88). "0" is stored and the excitation of the plunger (70) is turned off.

As described above, each time the mounting head (15) intermittently rotates, the chip component (4) is sucked by the suction nozzle (14) and moves to the next stop position of the intermittent rotation. When the suction nozzle (14) sucking the chip component (4) stops at the recognition station due to the intermittent rotation of the table (13), the component recognition device (17) recognizes the displacement of the component (4). .

Next, when the suction nozzle (14) sucking the component (4) stops at the angle correction station, the nozzle rotation roller (1) is recognized based on the recognition result of the recognition device (17).
8), the suction nozzle (14) is rotated in the θ direction, and the positional deviation of the rotation angle of the component (4) is corrected.

Next, when the suction nozzle (14) sucking the component (4) stops at the mounting station, the XY table (1) on which the printed circuit board (5) is placed is moved to the X-axis motor (2) and the Y-axis. The rotation of the motor (3) allows the recognition device (1)
The component (4) is mounted at a predetermined position on the printed circuit board (5) by moving after the positional deviation recognized in (7) is corrected.

In this embodiment, the feed lever (64) capable of swinging the swing arm (60) is provided regardless of which of the chip suction stations of the rotor (34) and the rotor (35) is at the component suction position. However, for example, when the swing arm (60) can swing only when the chip suction station of the rotor (34) is at the component suction position and cannot swing when the rotor (35) is at the same position, You can do as follows.

That is, when the component (4) is no longer sucked from both the chip suction stations of the rotors (34) and (35), the chip suction station of the rotor (34) is stopped at the component suction position and the feed lever is stopped. (64) is moved to swing the swing arm (60) to supply the component (4) to the chip suction station of both rotors and suck the component (4).

Then, when sucking the component (4) from the feeder (8), the chip suction station of the rotor (35) is stopped at the component suction position to suck the component.

In this case, even if the feed lever (64) reciprocates, it does not hit the swing arm (60), so that the rotors (34) and (35) do not rotate, and the pin (7) does not rotate.
5) does not move, and the air passage (31) remains closed, so that it is not necessary to provide the plunger (70). Also,
The CPU (85) determines whether there is no component (4) in both chip suction stations of the rotors (34) and (35), or whether the component is removed from the rotor (34) and located in the rotor (35). To discriminate the state, a discriminating memory is provided, "0" and "1" are stored for each suction operation in correspondence with the two states, and the contents of the memory are read out and moved to either rotor as described above. It is only necessary to decide whether to do so.

In this embodiment, the bulk case (2
Since the width of the supply stand (6) in the moving direction of (0) is slightly smaller than the width of the bulk cassette feeder (8), the supply stand (6) is mounted back and forth as shown in FIG. 1, but the width of the case (20) is reduced. If it is smaller than half of the width of 8), it may be mounted side by side in the moving direction of the supply table (6).

Further, in this embodiment, the bulk case (2
0) is attached to each of the chutes (25) and (26).
In the lower part of 3), two chutes are formed so as to communicate with each other, a supply hole for discharging compressed air is provided in each of the chutes, and the aligned parts (4) are pushed out to the chute outlet side, so that a bulk case is formed. Can be attached only one.

Further, in this embodiment, the plunger (7
0) is provided, but an air cylinder or the like may be used instead. Also, it is assumed that the plunger (70) pulls the support shaft (67) of the feed swing lever (68) in FIG. The upper part of the support shaft (67) may be pressed, or the feed lever (64) may be pressed directly to the right side in FIG.

Further, the position of the chip suction station of the rotor (34) is on a straight line connecting the two locating pins (19), and the component (4) of the other tape feeder (7 ) is sucked by the suction nozzle (14). Tape position
Since the feeder (7) is on a straight line connecting two locating pins ( not shown ) , these positions are arranged on the supply table (6) at a pitch of 17 mm, and the 17 mm is used when the supply table (6) is moved. Become a reference. The position of the chip suction station of the rotor (35) is 17 mm from this position.
And a distance of 8.5 mm, which is half of the distance, is added or subtracted, and the moving distance of the supply table (6) for stopping the rotor (35) at the component suction position is calculated. Therefore, if the position of the rotor (34) is as described above, even if the position of the rotor (35) is not 8.5 mm away from the position of the rotor (34), the position of the rotor (34) can be freely selected and calculated when calculating the moving distance. Should be taken into account. In this case, the size of the rotors (34) and (35) can be changed.

However, there is a tape feeder (7) which is larger than that described above and can be mounted at a pitch 1.5 times 17 mm, and so that the feeder (6) can be efficiently mounted at a pitch of 8.5 mm. Locate pin (1)
When drilling the hole of 9), 8.5 mm is a reference for movement. In this case, it is convenient that the interval between the rotors (34) and (35) is 8.5 mm. Conversely, 8.5 mm
If the holes of the locating pins (19) are formed at a pitch, the bulk cassette feeder (8) is expanded to have a width of 25.5 mm, and the spacing and size of the rotors (34) and (35) are increased. Can also be increased.

The number of rotors is not two but three or more, and one or more racks are provided to intermittently rotate the third and subsequent rotors, and reciprocate together with the rack (56). Alternatively, three or more of them may be intermittently rotated at the same time. In this case, the chute and the chute air supply hole may be provided corresponding to the rotor.

Further, the pitch of the locate pins is 8.5.
If the distance is not mm, the present embodiment may be applied based on the pitch. Further, in the present embodiment, the rotor (34)
The feed lever (64) for rotating the (35) is driven by a drive source for rotating the turntable (13), so that the plunger (70) is used to turn the turntable (13).
Although the operation is not performed by the intermittent rotation, the feed lever cam (66) is rotated by an independent drive source regardless of the drive source that rotates the turntable (13).
If the ball screw is rotated or the feed lever (64) is reciprocated using an air cylinder or the like, the CPU (85) controls this drive source and the turntable (13) rotates intermittently. It is also possible to realize a case in which the feed lever (64) is not reciprocated.

In this embodiment, both the rotation of the rotors (34) and (35) and the reciprocating movement of the valve opening / closing pin (75) are linked by the swing of the swing arm (60). The reciprocating operation of (75) is not performed by the swing arm, but another mechanism similar to the reciprocating mechanism of the feed lever (64) is provided, and the reciprocation of the feed lever causes the rotation of the rotors (34) and (35). The pin (75) may be reciprocated by a drive source different from the drive source for driving the turntable (13).

As described above, according to the present invention,
The a component housing chamber and supply means component supplying device which is unitized be positioned on the feed table as an integral, further components yield
Delivery room and unitized supply means align loose parts
And a plurality of guide chutes for guiding to the suction position
Sending parts to the suction position via the guide chute
Since the supply means is provided , the supply mechanism does not become large, the labor required for replacement is reduced, and the space on the supply table can be effectively used while maintaining the strength of the component supply device itself. Moreover, if the same chip component is supplied by a plurality of chutes, even if the component supply capability of each of the chutes is small, it is possible to secure the supply amount of the entire component supply device.

Further, a plurality of guide chutes are communicated with the same component storage chamber , and a plurality of guide chutes and sending means are provided.
The supply means and the component storage chamber having
Because that can be a sufficient space component housing chamber even in a narrow space as compared with the case where each guide chute provided equipment housing. In particular, when a plurality of component storage chambers are to be provided in the width direction of the component supply device, there is an advantage that the space is difficult to obtain because the chute is connected to the component storage chamber, but a flat space is difficult to obtain. . Also, when a plurality of component storage chambers are provided before and after in the longitudinal direction of the component supply device, if the component supply devices are arranged adjacent to each other, the component storage room on the component suction position side is difficult to see, and the remaining amount of components is not confirmed. Easily, if the component type is displayed in the component storage room, it is difficult to confirm the display, but there is an advantage that such a case does not occur.
