That is, the suppressor (43) is lowered as shown in FIG. 3 so that the suppressor (47) is hung on the pin (45) to hold the tape (18), and the screw (55) is loosened to loosen the support shaft. When the (44) is rotated, since the axis of the stripping plate fitting portion (58) in which the stripping plate (48) is fitted to the axis (60) is eccentric, the stripping plate (48) That is, the position of the stripping piece (53) changes, and the suppressor fitting portion (57) in which the suppressor (43) is fitted is not eccentric, so that the position of the suppressor (43) does not change and the gap of the gap (61) is reduced. Alternately, the gap (61) is slightly larger than the thickness of the cover tape (19), and the gap between the suppressor (43) and the tape (18) even if the peeled cover tape (19) becomes loose for any reason. Be sandwiched between If now there is no such gap, to fix the rotational position of the shaft (44) by tightening the screw (55).

Next, according to the type of the printed circuit board (5) on which the chip component (4) is to be mounted, the operator connects the component supply device (7) to the mounting pins (83) before and after the supply device (7).
Is positioned and attached to the supply table (6) by being inserted into a mounting hole (not shown) of the supply table (6).

As described above, when the supply device (7) is disposed on the supply table (6), the suction nozzle (12) sucks the component (4) from the supply device (7) and prints the printed circuit board. The operation of attaching to (5) is performed as follows.

First, when an operation unit (not shown) is operated to start automatic operation, a motor (3) is turned to supply a supply device (7) for supplying a desired component (4) via a ball screw (9). Suction nozzle (1 at standby)
The supply table (6) is guided and moved by the linear guide (10) so as to move to the suction position (P) of 2).

During this movement, the shutter lever (79) is moved around the shutter support shaft (78) by a spring (81) as shown in FIG.
The shutter (77) is moved in the tape feed direction, and the tape (1) is removed in a state where the upper cover tape (19) is peeled off.
8) It covers the part (4) enclosed in the inside and prevents the part (4) from jumping out during the movement.

When the supply device (7) stops, the lifting rod (2)

Will be recognized.

The nozzle (12) stopped at the recognition station due to the intermittent rotation of the next turntable (11) moves to the angle correction station, and is rotated by the nozzle rotation roller (1).
By 5), the displacement of the rotation angle in the θ direction of the component (4) is corrected based on the recognition result of the recognition device (14).

The nozzle (1) stopped at the angle correction station due to the intermittent rotation of the next turntable (11).
2) is moved to the mounting station, and the XY table (1) is corrected by the rotation of the X-axis motor (2) and the Y-axis motor (3) based on the recognition result of the recognition device (14).
The component (4) sucked by the nozzle (12) is mounted at a position where the printed board (5) is to be mounted.

The above operation is repeated, and the components (4) are sequentially sucked from the respective component supply devices (7).

In this way, the tape (18) wound on the reel (not shown) is gradually shortened, and when the material eventually runs out, the running out of the material is detected by detecting a continuous suction error of the part (4) and the like, and This is reported to the user by a notifying device (not shown).

Next, the operator stops the component mounting operation using an operation key (not shown), and replaces the component supply device (7) that has run out of material.

That is, when the supply device (7) is removed from the supply table (6), the suppressor pressing piece (47) is removed from the pin (45) of the supply device (7), and the suppressor (43) is lifted, the suppressor (43) is lifted. 43) is engaged with the peeling plate (48) and lifts up against the urging force of the spring (52), and the suppressor (43) and the peeling plate (48) are supported by the support shaft (44).

Next, a new tape (18) is mounted on the chute surface (37), and the feed pin (39) is inserted into the feed hole (3).
8), the tip of the cover tape (19) is wound around the reel (69) through the opening (54) and the gap (61), and then a force is applied to lower the suppressor (43). The protruding piece (62) presses the engaging protruding part (63), and swings the swing lever (22) clockwise against the urging force or the frictional force of the spring (27). 4
3) is rotated clockwise around the spindle shaft (44) and descends to a position where the tape (18) is pressed.

Thereafter, the pressing piece (47) is engaged with the pin (45), and the suppressor (43) presses the tape (18) by the spring (46).

Next, the component supply device (7) is mounted at a predetermined position on the supply table (6) in the same manner as described above, and the chip component (4) is mounted on the printed circuit board (5) in the same manner as described above. Operation continues.

In this embodiment, the suppressor (43) and the stripping plate (48) are rotated around the same shaft (44), but they are located at different positions.
You may make it each rotate around a spindle of a book.
In this case, for example, the fulcrum of the suppressor (43) may be on the right side of FIG. 3 with respect to the suction position (P).
Considering the replacement of 8) and the attachment to the supply stand (6), the left side of the suction position (P) which does not hinder is better.
