When the pulled-out component storage body 14 is placed on the upper surface of the drawer table 24, the elevating motor 73 is operated to raise the drawer table 24 to the component supply height shown in FIG. When the drawer table 24 is located at the component supply height, the component 3 stored in the component storage body 14 is ready to be picked up by the mounting head 13.

When the component storage body 14 is inserted into the slot 44 having the slot number "n" in a horizontal position, the component storage body 14 is supported by a pair of rails 45 whose left and right ends form the slot 44 having the slot number "n". (FIG. 13 (a)). On the other hand, when the component accommodating body 14 is inserted into the slot 44 in the slot number “n” not in a horizontal posture but in an oblique posture in which the heights of the left and right ends are different (adjacent in the vertical direction). (When inserted across a plurality of located slots 44), one end of the component housing 14 is supported by a rail 45 constituting slot 44 with slot number "n", and the other end is supported. It is in a state of being supported by the rail 45 constituting the slot 44 having the slot number “n-1” (FIG. 13 (b)). Alternatively, one end is supported by the rail 45 constituting the slot 44 having the slot number “n”, and the other end is supported by the rail 45 constituting the slot 44 having the slot number “n + 1” (). FIG. 13 (c)).

As shown in FIG. 13 (b) or FIG. 13 (c), when the component storage body 14 is inserted into the slot 44 in an oblique posture, the left and right end portions 61T of the engagement rod 61 are inserted into the component storage body. The parts accommodating body 14 cannot be pulled out onto the drawer table 24 because it cannot be engaged with the engaged block 54 of the pallet 51 of 14. Therefore, when the component accommodating body 14 is inserted into the slot 44, the operator OP needs to be careful so that the component accommodating body 14 is inserted into the slot 44 in a horizontal posture.

In the present embodiment, the structure is such that the worker OP is prevented from accidentally inserting the component storage body 14 into the slot 44 in an oblique posture. Further, even if the component storage body 14 is accidentally inserted into the slot 44 in an oblique posture, the drawer mechanism 62 can detect this before the component storage body 14 is pulled out. Hereinafter, these configurations will be described.

In FIG. 7, the plurality of slots 44 included in the magazine 23 have a configuration in which the first slot 44a and the second slot 44b are alternately arranged in the vertical direction. Here, the first slot 44a is a slot 44 in which the width W of each of the pair of rails 45 has the first dimension W1. Further, the second slot 44b is a slot 44 having a second dimension W2 in which the width W of each of the pair of rails 45 is different from the first dimension W1 (larger than the first dimension W1).

As described above, in the present embodiment, the pair of rails 45 constituting each of the plurality of slots 44 of the magazine 23 have the same width W as each other, and constitute another slot 44 located adjacent to each other in the vertical direction. It has a width W different from that of the pair of rails 45.

Therefore, when the component storage body 14 is inserted into the slot 44 of the magazine 23, the operator OP visually confirms that the width W of the rail 45 of the slot 44 matches on the left and right (both ends of the component storage body 14). By confirming and further confirming while touching the rail 45 with both hands, it is possible to confirm that the two rails 45 are at the same height position. As a result, it is possible to prevent the operator OP from accidentally inserting the component storage body 14 into the slot 44 in an oblique posture.

Further, as shown in FIG. 7, identification marks 46 having the same identifier are located in the vicinity of each of the pair of rails 45 constituting the slot 44 (here, the front end surfaces 41T of each of the left and right side plates 41 of the magazine 23). Is provided. The identification mark 46 has a different identifier from the identification mark 46 attached in the vicinity of each of the pair of rails 45 constituting the other slots 44 located adjacent to each other in the vertical direction.

The identifier is, for example, a color, and in the present embodiment, the color of the identification mark 46 attached corresponding to one slot 44 is the color of the identification mark 46 provided corresponding to the slot 44 on the upper stage side thereof. It is also different from the color of the identification mark 46 provided corresponding to the slot 44 on the lower stage side. In the present embodiment, the white mark 46a with white, whose identifier is the first color, and the black mark 46b, whose identifier is black, which is a second color different from the first color, are Z. They are arranged alternately in the axial direction.

When the component accommodating body 14 is inserted into the slot 44 of the magazine 23, the operator OP visually recognizes the identification mark 46 attached to the position near each of the pair of rails 45 constituting the slot 44, and the identification mark 46 It can be confirmed that the two rails 45 are at the same height position by the fact that the two rails 45 match on the left and right (if the identifier is a color). Therefore, it is possible to more reliably prevent the component storage body 14 from being accidentally inserted into the slot 44 in an oblique posture.

In FIGS. 4 and 9 (a) and 9 (b), a sensor mounting arm 91 extending rearward from each of the left and right ends of the drawer table 24 is provided on the rear end side of the drawer table 24, and these 2 A detection sensor 92 is attached to the tip end portion (front end portion) of each of the sensor mounting arms 91. The two detection sensors 92 mounted on the two sensor mounting arms 91 are located facing each other in the X-axis direction. One of these two detection sensors 92 is a floodlight 92a and the other is a light receiver 92b.

In FIGS. 9 (b) and 11 (a) and 11 (b), the distance between the floodlight 92a and the light receiver 92b is larger than the dimension of the component housing 14 in the X-axis direction (of the pallet 51). The floodlight 92a projects the inspection light 93 in the horizontal direction (X-axis direction) toward the light receiver 92b, and the light receiver 92b outputs a light receiving signal to the control device 80 when the inspection light 93 is received (FIG. 10). ).

The control device 80 causes the floodlight 92a to project the inspection light 93 with the drawer table 24 located at the height of the slot 44. The inspection light 93 projected by the floodlight 92a is a light receiver 92b because the inspection light 93 is not blocked by anything when the component storage body 14 is not inserted in the slot 44 at the height of the drawer table 24. (Fig. 9 (a)). At this time, the detection sensor 92 is in a “non-detection state” in which the component housing 14 is not detected. On the other hand, when the component storage body 14 is inserted into the slot 44, the light is not received by the light receiver 92b because it is blocked by the component storage body 14 inserted into the slot 44 (FIG. 9B). At this time, the detection sensor 92 is in the “detection state” in which the component housing 14 is detected.

Here, when the inspection light 93 is blocked by the component accommodating body 14, when the component accommodating body 14 is in the horizontal posture, the engaged block 54 included in the component accommodating body 14 (specifically, the engaged block 54 on the floodlight 92a side). It is blocked by the block 54) (FIG. 9 (b)). On the other hand, when the posture of the component storage body 14 is an oblique posture, the inspection light 93 is blocked by the upper surface or the lower surface of the component storage body 14.

As described above, in the present embodiment, the detection sensor 92 is a component storage body at a position at a height of the inspection light 93 based on whether or not the inspection light 93 projected in the horizontal direction is blocked by the component storage body 14. The presence or absence of 14 is detected.

In FIG. 10, the control device 80 includes a posture detection unit (detection unit) 80b. The posture detection unit 80b performs a posture check (posture detection) to detect the posture of the component storage body 14 inserted in the slot 44 based on the detection information of the detection sensor 92. Specifically, the posture check is based on whether the detection sensor 92 is in the "non-detection state" or the "detection state" at the timing when the detection sensor 92 is moved up and down and the inspection light 93 is projected. , By checking for the presence or absence of the component accommodating body 14 at a plurality of heights in a certain area in the vertical direction including the slot 44.

In the posture check, if it is known that the component storage body 14 is inserted into the slot 44 of the slot number "n" based on the production data stored in the storage unit 80a, the component storage body 14 is checked. Is executed before withdrawing to the drawer table 24 (for example, immediately after the component housing 14 is inserted into the slot 44). In the procedure of the posture check (posture detection method of the parts storage body 14), the posture detection unit 80b raises and lowers the detection sensor 92, and the presence or absence of the parts storage body 14 at a plurality of heights in a certain region in the vertical direction including the slot 44. After executing the step (inspection step) of checking, the step (posture) of determining the posture of the component storage body 14 inserted in the slot 44 based on the inspection result (detection information of the detection sensor 92) obtained in the inspection step. Judgment process) is executed.

When detecting the posture of the component storage body 14 in the slot 44 of the slot number “n”, first, the posture detection unit 80b operates the elevating mechanism 25 to raise and lower the drawer table 24, and the detection sensor 92 is moved to the slot number “n”. It is positioned at the height of each slot 44 in the order of "n-1", "n", and "n + 1" (FIG. 14). Then, every time the detection sensor 92 is located at the height of each slot 44, the inspection light 93 is projected from the floodlight 92a, and the state of the detection sensor 92 (“detection state” or “non-detection state” is set. Inspect (inspection process). Here, the vertical region including the positions of the slots 44 of the slot numbers “n-1”, “n”, and “n + 1” is a region corresponding to a fixed vertical region including the slot “n”.
