  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic configuration diagram of a workpiece three-dimensional rotating device in a cleaning machine according to the present invention, and FIG.

  As shown in FIGS. 1 and 2, the workpiece three-dimensional rotating device 1 in a cleaning machine is used in a cleaning machine that showers and cleans a workpiece W that is a cleaning target component on a workpiece receiving portion 11 that supports the workpiece. The workpiece receiving portion 11 on which the workpiece is supported (held) is three-dimensionally rotated. Here, the three-dimensional rotation includes rotation in combination with rotation around the horizontal axis and rotation around the vertical axis in addition to rotation around the horizontal axis and rotation around the vertical axis of the work receiving portion 11. Means.

  The workpiece receiving portion 11 includes a frame-shaped main body portion 12 that supports (holds) the workpiece, and columnar first and second support shaft portions 13 and 14. The first and second support shaft portions 13 and 14 are provided outside the opposing side wall portions 12a and 12b of the main body portion 12, and protrude in opposite directions. And both the 1st and 2nd support shaft parts 13 and 14 have a central axis used as a horizontal axis.

  One end portion of the first support shaft portion 13 is fixed to the side wall portion 12 a of the main body portion 12 and is integrated with the main body portion 12 so as not to rotate. On the other hand, one end portion of the second support shaft portion 14 is attached to the side wall portion 12 b of the main body portion 12 via the idler rotation bearing 15, and is integrated with the main body portion 12 so as to be rotatable. Here, since the first and second support shaft portions 13 and 14 are rotated in the opposite directions, the second support shaft portion 14 is not directly coupled to the work receiving portion 11 but is coupled via the idler rotation bearing 15. Thus, the edge of rotation is cut from the workpiece receiving portion 11. That is, the second support shaft portion 14 serves as a guide shaft for the idler.

  The other ends of the first and second support shafts 13 and 14 are sandwiched between first and second annular disks 21 and 22 arranged in parallel to each other, and not only around the horizontal axis but also on the horizontal axis. It is supported so that it can also rotate around the vertical axis in the orthogonal direction. And the main-body part 12 is located in the center opening of both the annular discs 21 and 22 so that rotation is possible.

  The first and second annular disks 21 and 22 are rotatably supported by a support mechanism (not shown) around a vertical axis (the central axis of both annular disks 21 and 22).

  In this way, support means for supporting the work receiving portion 11 through the support shaft portions 13 and 14 so as to be rotatable around the horizontal axis and the vertical axis is configured.

  The first and second annular discs 21 and 22 are provided with annular rack portions 23 and 24 extending continuously in the circumferential direction on the respective inner side surfaces (opposing surfaces), and the first and second support shaft portions 13 are provided. , 14 are formed with pinion portions 16, 17 that mesh with the rack portions 23, 24 rotatably at positions corresponding to the rack portions 23, 24 of the first and second annular disks 21, 22, respectively.

  Here, the mechanism in which the rack portions 23 and 24 and the pinion portions 16 and 17 are engaged with each other is that the first and second annular disks 21 and 22 and the first and second support shaft portions 13 and 14 are engaged. This is to prevent slip (empty sliding) from occurring. This is because the present invention does not hold when slip occurs. However, the present invention is not limited to a mechanism in which the rack portions 23 and 24 and the pinion portions 16 and 17 mesh with each other.

  As a result, when the first and second annular discs 21 and 22 are rotated in the same direction around the central axis (vertical axis) at the same speed, the first and second support shaft portions 13 and 14 are rotated around the horizontal axis. Does not rotate. Therefore, the workpiece receiving portion 11 rotates around the vertical axis together with the first and second annular disks 21 and 22 without rotating around the horizontal axis.

  Further, when the first and second annular discs 21 and 22 are rotated in the opposite directions around the vertical axis, the first and second support shaft portions 13 and 14 are rotated in the opposite directions, and the work receiving portion 11 is rotated around the horizontal axis. Will rotate.

  In addition, with respect to the first and second annular discs 21 and 22 sandwiching the first and second support shaft portions 13 and 14, a spacing regulating means is provided on the outer surface so that the spacing between them is not widened. . By this distance regulating means, the distance between the first and second annular disks 21 and 22 is maintained, and rotation is allowed in this state.

  The first and second support shafts 13 and 14 sandwiched between the first and second annular disks 21 and 22 move relative to the first and second annular disks 21 and 22 while rotating like rollers. However, at this time, the first and second annular discs 21 and 22 are in contact with the ends of the support shafts 13 and 14 so that the first and second support shafts 13 and 14 do not move in the axial direction. The shafts 13 and 14 are restricted from moving in the axial direction. As a result, the center of the work receiving portion 11 coupled to the first and second support shaft portions 13 and 14 is always maintained at the rotation center of the rotating plates 21 and 22.

  Further, first and second chain members 25 and 26 are provided on the outer peripheral portions of the first and second annular disks 21 and 22. First and second sprocket members 27 and 28 mesh with these first and second chain members 25 and 26 in a rotatable manner. The first and second sprocket members 27 and 28 are configured to be rotationally driven by motors 29 and 30 with speed reducers that can rotate forward and reverse. The motors 29 and 30 are variable speed motors so that the rotational speed around the horizontal axis and the rotational speed around the vertical axis can be arbitrarily adjusted.

  In this way, the first and second annular discs 21 and 22 are horizontally rotated in the same direction around the vertical axis to rotate the work receiving portion 11 around the vertical axis, while the first and second annular discs 21, Driving means for rotating the work receiving portion 11 around the horizontal axis is configured by rotating 22 in the reverse direction.

  Both motors 29 and 30 are linked to a rotation control means 41, and the rotation control means 41 controls the rotation direction and the rotation speed.

  Therefore, the rotation direction of the motors 29 and 30 is controlled to rotate the work receiving part 11 around either the horizontal axis or the vertical axis, or while rotating the work receiving part 11 around the horizontal axis. It can also be rotated around. In this case, the rotational speeds of the motors 29 and 30 can be controlled to control the rotational speed of the workpiece receiving unit 11.

  When the first and second support shafts 13 and 14 are sandwiched between the first and second annular disks 21 and 22 and rotated around the vertical axis in the same direction at the same speed, the first and second support shafts 13 are provided. , 14 do not rotate, but rotate according to the rotation of the first and second annular disks 21, 22. When the rotational speeds of both the annular plates 21 and 22 are changed, the first and second support shaft portions 13 and 14 rotate, and the work receiving portion 11 rotates around the horizontal axis, while the first and second annular plates 21 and 22 rotate. Rotate in accordance with 22 rotations.

  When the speed difference between the rotation speeds of the annular plates 21 and 22 is small, the rotation speed of the work receiving part 11 (first and second support shaft parts 13 and 14) is low. Conversely, when the speed difference is large, the work receiving part 11 The rotation speed of the (first and second support shaft portions 13 and 14) increases, and the workpiece receiving portion 11 rotates in accordance with the rotation of the first and second annular discs 21 and 22.

Here, the rotational speed Vf at which the workpiece receiving portion 11 (the first and second support shaft portions 13 and 14) rotates around the vertical axis is an average of the rotational speeds V1 and V2 of the annular plates 21 and 22. That means
Vf = (V1 + V2) / 2
It becomes.

  Further, since ΔV / (D x π) is the rotational speed of the first support shaft portion 13, if the diameter of the support shaft portions 13 and 14 is small even if the speed difference ΔV is the same, the rotational speed is large. On the contrary, if the diameter is large, the number of rotations becomes small. In any case, the traveling speeds of the support shafts 13 and 14 are the same.

  On the other hand, the rotational speed (number of rotations) at which the work receiving part 11 (first and second support shaft parts 13 and 14) rotates around the horizontal axis is determined by the diameter of the first and second support shaft parts 13 and 14 and the annular disk. It can be calculated by the speed difference between the rotational speeds of 21 and 22.

  As described above, when the rotational speeds (rotations) of the annular disks 21 and 22 are changed, the work receiving portion 11 coupled to the first support shaft portion 13 rotates about the horizontal axis while rotating about the vertical axis. Will do.

  Therefore, the workpiece to be cleaned placed on the workpiece receiving portion 11 can be cleaned while performing not only horizontal rotation on the rotary table similar to the conventional one but also vertical rotation at the same time, thereby improving the efficiency of cleaning.

  That is, as shown in FIG. 6, conventionally, the entire surface (six surfaces) of the workpiece W to be cleaned placed on the rotary table 102 in mesh with the sprocket 101 that is rotationally driven and the outer peripheral chain 103 of the rotary table 102 is cleaned. In order to do this, the nozzle blocks 104, 105, and 106 in three directions of the side nozzle, the upper surface nozzle, and the lower surface nozzle are basically required, but the first and second annular plates 21 and 22 and the work receiving portion 11 are supported. The above-described rotating device using the shaft portions 13 and 17 can clean the entire surface of the workpiece by directing two sets of nozzles in the horizontal rotation direction and the vertical rotation direction to the workpiece, thereby realizing an efficient cleaning. .

  Further, by changing the speeds of the first and second annular disks 21 and 22, the rotational speed around the horizontal axis line according to the nature (size, shape,...) Of the work W placed on the work receiving portion 11. The (longitudinal rotation speed) and the rotation speed around the vertical axis (horizontal rotation speed) can be arbitrarily adjusted, and the cleaning mode can be made to flexibly correspond to the workpiece W that is the part to be cleaned.
