It has been. The interval between the pair of pressing roller mounting plates 214 is configured to be approximately equal to the width dimension of the component supply unit 141 in the X-axis direction. Therefore, the pair of roller mounting plates 211 serves as a reference for roughly positioning the component supply unit 141 with respect to the mounting unit 200 in the X-axis direction.

  The pressing roller mounting plate 214 is provided with a pressing roller 213 having a rotation shaft extending in the X-axis direction. The pressing rollers 213 are provided at a total of four locations, two at each pressing roller mounting plate 214.

  Note that, as described above, when the mounting member 141 is supported by each support guide roller 212, each pressing roller 214 comes into contact with the upper surface of the above-described regulation guide 145.

  The engaging portion 220 is disposed at a substantially central portion in the X-axis direction of the pair of support guide roller mounting plates 211 so as to extend in the Y-axis direction, and has substantially the same length as the support guide roller mounting plate 211. A roller mounting plate 222 and an engagement roller 221 having a rotation axis parallel to the Z axis are provided. One end of the engagement roller mounting plate 222 extends to the end plate 230. The engagement roller 221 is provided at three locations near and at both ends of the engagement roller mounting plate 222.

  When the component supply unit 140 is inserted into the attachment unit 200, the two engagement rollers 221 and the mounting unit side engagement unit 141a that are initially engaged are fitted into each other, so that the component supply unit 141 in the X-axis direction is inserted. Is guided along the Y-axis direction. Thereafter, the mounting portion side engaging portion 141a is engaged with the remaining one engaging roller 221 provided at the innermost position, and the three engaging rollers 221 and the mounting portion side engaging portion 141a are in contact with each other. By contact, the position of the component supply unit 141 in the X-axis direction is determined. In FIG. 3, three engagement rollers 221 are provided, but four or more engagement rollers 221 may be provided.

  The end plate 230 is a member to which the attachment unit support plate 235 provided at the upper end, the supply device presence / absence sensor 234 for detecting the presence / absence of the component supply device 15, and the supply device presence / absence sensor 234 are attached. And a pair of sensor mounting plates 233 provided on the upper portion of the plate 235. The attachment portion support plate 235 is fixed to the component mounting apparatus frame member 350, and a plurality of air supply holes penetrating in the Y-axis direction are formed at equal intervals in the X-axis direction. When the component supply unit 140 is attached to the attachment unit 200, the supply hole and a supply port (not shown) of each component supply device 15 are connected, and air is supplied from the main body of the component mounting device 300 to the component supply device 15. It is like that.

  When the component supply unit 140 is attached to the attachment unit 200, as shown in FIG. 9, the component supply unit air supply valve 620 is opened and closed by the control of the control unit 600 based on the data in the storage unit 610, Air is supplied to the component supply unit 141. The sensor attachment plate 233 is fixedly provided on the upper portions of both ends along the X-axis direction of the attachment portion support plate 235, and the supply device presence / absence sensor 234 is fixed to the sensor attachment plate 233, respectively.

As the supply unit arrival confirmation sensor 236, for example, a limit switch or the like can be used, and a signal is sent to the control unit 600 when the component supply unit 141 comes into contact with the end plate 230. After recognizing the signal from the supply unit arrival confirmation sensor 236, the control unit 600 performs processing so as to confirm whether or not the component supply device 15 is mounted on the component supply unit 141 by the supply device presence / absence sensor 234. When the component supply device 15 is not mounted on the component supply unit 140, air is not supplied to the component supply device 15.

  Next, the operation of attaching the component supply unit 140 to the attachment unit 200 together with the component supply device batch replacement cart 100 will be described using the flowchart of FIG. In addition, the parts supply apparatus collective exchange cart 100 and the attachment part 200 to be described are the same as those in FIGS.

  First, the case where the lower surface 141b of the component supply unit is located between the shaft support position 40 of the support guide roller 212 and the virtual support surface 50 will be described.

  In step 1, the component supply unit 140 is moved to a position where the supply roller side engagement unit 141a can be engaged with the engagement roller 221 (so that the support roller mounting member 211 is supported by the lower surface 141b of the component supply unit). The entire cart for exchange is moved to perform rough positioning in the X-axis direction.

  In step 2, the component supply unit 140 is moved from the rough positioning position in the Y-axis direction together with the component supply device batch replacement cart 100, and the component supply unit 141 is placed on the support guide roller 212. At this time, the component supply unit 141 is lifted in the Z-axis direction by the support guide roller 212, and is urged downward by the urging force of the spring 133 to be positioned in the Z-axis direction. At the same time, the supply portion side engaging portion 141a is engaged with the engaging roller 221 so that the component supplying portion 140 is positioned in the X-axis direction. Further, the component supply unit 141 is positioned along the Y-axis direction by contacting the end plate 230. At this point, the positioning of the component supply unit 141 with respect to the attachment unit 200 along the X-axis, Y-axis, and Z-axis directions is completed.

  In this way, while moving the component supply unit 140 along the Y-axis direction (along the mounting direction 30), the component supply unit 140 is simultaneously moved along the Z-axis direction by the support unit 210 and the spring. Compared to the case where the component supply unit 140 is positioned along the Z-axis direction by separately moving along the Y- and Z-axis directions by being placed on the support guide roller 212 and positioned by the urging force of 133. Thus, the number of operation steps for positioning can be reduced.

  That is, conventionally, many steps are required over many steps, but according to the present embodiment, the component supply unit 140 is divided into two steps: positioning in the X-axis direction before insertion and insertion of the component supply unit 140. Can be installed. This reduction in the number of steps can shorten the time for attaching the component supply unit 140 to the attachment unit 200, and can improve the productivity of the component mounting apparatus 300.

  On the other hand, a method of attaching the component supply unit 140 to the attachment unit 200 when the lower surface 141b of the component supply unit is lower than the pivot support position 40 will be described with reference to FIGS. In this case as well, in step 1, similarly, the engagement roller 221 can be engaged with the supply portion side engagement portion 141a (so that the support roller mounting member 211 is supported by the lower surface 141b of the component supply portion). The component supply unit 140 is moved together with the component supply device batch replacement cart to perform rough positioning in the X-axis direction.

  In step 2, an external force is applied downward to the handle 121 so that the lower surface tip 141c of the lower surface 141b of the component supply unit is positioned above the support virtual surface 50, and the holding member 131 is tilted with the rotation shaft 123 as a fulcrum. . At this time, the lower surface tip portion 141c of the component supply unit 141 is raised, and the lower surface tip portion 141c is positioned above the shaft support position 40. Next, with the holding member 131 tilted (while applying an external force downward to the handle 121), the component supply unit 140 is moved along the Y-axis direction until the lower surface tip 141c is placed on the support guide roller 212. Move to. At this time, the inclination of the holding member can be fixed by engaging the engagement pin 125 of the elongated hole 122a of the handle 121 with the rotation stop holding plate 124.

  Next, when the tip of the component supply unit 141 is completely placed on the support guide roller 212, the downward external force applied to the handle 121 is released (FIG. 10). Then, the component supply unit 141 is placed on the support guide roller 212, and the holding member 131 returns to the original position (FIG. 11).

  In this state, by moving the component supply device collective replacement cart 100 along the Y-axis direction, the component supply unit 141 is positioned along the X, Y, and Z-axis directions in the same manner as described above (FIG. 12). In this way, even when the lower surface 141b of the component supply unit is lower than the pivot support position 40, the component supply unit unit 140 is tilted to raise its tip, thereby supporting the lower surface 141b of the component supply unit. Can be placed on top. As a result, the lower surface 141b of the component supply unit can move the component supply unit 140 along the Y-axis direction and position it along the X, Y, and Z directions.

  In addition, by urging the component supply unit 141 in a direction to come into close contact with the support guide roller 212 by the spring 133, the lower surface 141b of the component supply unit 140 comes into contact with the support virtual surface 50 without any gap. As a result, the component supply unit 141 is stably positioned along the Z-axis direction, and the component supply unit 140 can be attached to the mounting unit 200 with fewer steps, and the productivity of the component mounting apparatus 300 can be improved. .

  Further, since the component supply unit 141 travels on the support guide roller 212 of the support unit 210, the force applied to move the component supply unit 140 in the Y-axis direction can be reduced.

  Further, the component supply unit 140 engages with the engagement roller 221 and is guided along the Y-axis direction, while being restricted from moving in the X-axis direction by the pressing roller mounting plate 214 and the engagement roller 221. The component supply unit 140 can be positioned with high accuracy.

  Next, a modified example of the component mounting apparatus according to the present embodiment will be described. FIG. 14 is a diagram illustrating a schematic configuration of a parts supply device collective replacement cart according to a first modification. The parts supply device batch replacement cart 100 includes a supply device aligning member 142 at the tip end in the Y-axis direction of the component supply unit 140. The supply device aligning member 142 is a plate-like member provided so as to protrude from the upper surface of the component supply unit 141. When a plurality of component supply devices 15 are mounted on the component supply unit 141, the positions of the component supply devices 15 in the Y-axis direction need to be aligned. According to the parts supply device collective replacement cart according to the present modification, when each component supply device 15 is mounted, a plurality of component supply devices are mounted by mounting the supply device aligning member 142 with its tip abutting. 15 can be mounted along the Y-axis direction.

As shown in FIG. 15, a positioning pin 151 is attached to the right end surface of the Y-axis of each component supply device 15 according to this modification. The end plate 230 of the attachment unit 200 is provided with a plurality of positioning holes 215 for positioning the attached component supply device 15 on the attachment side surface. As shown in FIG. 16, when the positioning pin 151 of each component supply device 15 attaches the component supply unit 140 to the mounting portion 200, the positioning pin 151 fits into the positioning hole 215 described above, and each component supply device 15 is connected to the component supply portion 200.
