Next, the operation of the component supply device 1 of this embodiment will be described.
As shown in FIGS. 1 to 3, the movable plate 11 of the gantry 2 is urged upward in the ZX direction by the first coil spring 16, and downward by the first adjusting bolt 17 against this urging force. By being pressed, it is maintained in a stable state at a predetermined height without being displaced in the Z direction or tilted. In addition, the second coil spring 19 is urged to one side in the X direction, and the second adjustment bolt 20 is pressed against the urging force to the other side in the X direction. Therefore, it is kept stable without being displaced. Similarly, it is urged to the Y direction one side by the third coil spring 21 and pressed against the other side in the Y direction by the third adjusting bolt 22 against this urging force. The position is kept stable without displacement. For this reason, the vibration part 5 of the parts feeder 3 can be driven in the state positioned correctly in a Z direction, an X direction, and a Y direction, and the components on the bowl 4 can be selected and conveyed.

  Moreover, in order to adjust each position of the Z direction of the parts feeder 3, an X direction, and a Y direction, it carries out as follows. First, in order to adjust the position in the Z direction, the first adjustment bolts 17A, 17B, and 17C are rotated and moved forward and backward in the Z direction. That is, in order to adjust the position of the parts feeder 3 downward in the Z direction, the first adjusting bolt 17 is rotated around the axis and advanced downward in the Z direction. At this time, the movable plate 11 is maintained in a state of being biased upward in the Z direction by the first coil spring 16, and is always in contact with the tip of the first adjustment bolt 17. Thus, by moving the first adjustment bolt 17 downward in the Z direction, the movable plate 11 moves downward in the Z direction while following the first adjustment bolt 17 against the biasing force of the first coil spring 16.

It will move upward in the Z direction while following the adjustment bolt 17. For this reason, it is possible to easily and accurately adjust the position in the Z direction while maintaining the movable plate 11 in a stable state by simply adjusting the position of the first adjustment bolt 17 in the Z direction. The movable plate 11 can be kept in a stable state and accurately positioned and held by the urging force of the coil spring 16 and the pressing force of the first adjusting bolt 17. In particular, each first adjustment bolt 17 is disposed opposite to each of the first coil springs 16 so that the movable plate 11 can be held in a more stable state and can be adjusted in position.

  Further, in order to adjust in the X direction, the second adjusting bolts 20A and 20B are rotated and moved forward and backward in the X direction. Similarly, the position of the movable plate 11 can be easily and accurately adjusted in the X direction while keeping the movable plate 11 in a stable state only by advancing and retracting the second adjustment bolt 20 by urging by the second coil spring 19. In addition, by providing a scale on each of the second adjustment bolts 20A and 20B so that the advance / retreat amount can be visually observed, the advance / retreat amount is made equal, and the movable plate 11 is adjusted so as not to rotate and move on the horizontal plane. be able to.

  Similarly, when adjusting in the Y direction, the third adjusting bolt 22 is advanced and retracted in the Y direction, so that the movable plate 11 can be easily and accurately maintained in a stable state by the urging by the third coil spring 21. The position can be adjusted in the Y direction. Here, the Y direction to be adjusted is guided by two second adjustment bolts 20 for adjusting the orthogonal X direction. For this reason, the adjustment in the Y direction can be easily and accurately adjusted by one third adjusting bolt 22 without rotating the movable plate 11 on the horizontal plane.

  Here, the first coil spring 16, the second coil spring 19, and the third coil spring 21 are in contact with the movable plate 11 via washers 16a, 19a, and 21a, respectively, so that they can slide. Further, the first adjustment bolt 17, the second adjustment bolt 20, and the third adjustment bolt 22 also only come into contact with the movable plate 11. For this reason, the movable plate 11 can be smoothly moved when the position is adjusted in the Z direction by the first adjustment bolt 17. Similarly, the movable plate 11 can be smoothly moved when the second adjustment bolt 20 and the third adjustment bolt 22 are adjusted in the X direction and the Y direction, respectively. In particular, in this embodiment, the first coil spring 16, the second coil spring 19, and the third coil spring 21 are provided with washers 16a, 19a, and 21a between the movable plate 11, so that the movable plate 11 movement is made smoother. The movable plate 11 can be moved more smoothly by filling grease or the like between the washers 16a, 19a, 21a and the movable plate 11.

  As described above, in the component supply device 1 of the present embodiment, the first coil spring 16 and the first adjustment bolt 17 are provided, so that the number of components can be reduced in the Z direction without increasing the device weight. Adjustment can be performed easily and accurately. Further, by providing the second coil spring 19 and the second adjustment bolt 20, and the third coil spring 21 and the third adjustment bolt 22, it is possible to reduce the number of parts on the horizontal plane without increasing the apparatus weight. Adjustment can be performed easily and accurately.

  Here, the first coil spring 16 urges the movable plate 11 upward in the Z direction, and the first adjustment bolt 17 presses the movable plate 11 downward in the Z direction. The first coil spring 16 is supported. As a result, only the force obtained by subtracting the weight of the movable plate 11 and the weight of the parts feeder 3 fixed to the movable plate 11 from the biasing force of the first coil spring 16 acts on the first adjustment bolt 17 as a reaction force. Will be. For this reason, compared with the structure in which the first coil spring 16 is biased downward in the Z direction and the first adjustment bolt 17 is pressed upward in the Z direction, the first adjustment bolt 17 is moved forward and backward more easily. Adjustment of the plate 11 in the Z direction can be performed.
