Abstract

PURPOSE:To provide a controlling device for the direction of a work in which resources are performed so as to obtain a state wherein all faces of the work are evenly directed in every direction by rotating a rotor around a first shaft and also rotating the rotor even around a second and a third... shafts unparallel to the first shaft. CONSTITUTION:A rotor 14 rotating around a first shaft 17 is rotated even around a second and a third... shafts unparallel to the first shaft. Further the respective speeds of rotation around a plurality of shafts can be individually controlled. As a result, a controlling device for the direction of a work is provided in which resources are performed so as to obtain a state wherein all faces of the work are evenly directed in every direction. For example, draining or the like is completely performed and the necessary time of draining is shortened. The rate causing a scratch on the work is reduced.

2. Description of the Related Art Conventionally, for example, a cap nut (workpiece) is placed in a cylindrical basket having a horizontal shaft, and this is rotated around a horizontal shaft so that the cap nut is retained in the recess of the cap nut. Devices for draining liquids that are present are known.

[0003]

In the liquid removing device described in the above conventional technique, the cap nut (work) is
When the liquid is drained around a horizontal axis in a certain direction, and the opening of the recess of the cap nut (workpiece) or the like is in a direction perpendicular to the certain direction and difficult to drain. Is often incompletely deliquored, and has the disadvantage that it must continue to rotate for a relatively long period of time to cover the incomplete liquation. If the rotation continues for a long time, the rate at which the cap nut (work) or the like is rubbed and scratched increases accordingly, which is not preferable.

According to the present invention, the concave portion in any direction of the work such as the cap nut always faces downward, so that the above-mentioned various problems are solved, that is, the entire surface (all directions) of the work is in a fixed direction. On the other hand, a device to obtain a state in which the workpiece faces on average, in other words, a device to obtain a state in which all surfaces of the workpiece are evenly oriented in any direction, and further, the concave portion of the workpiece such as a cap nut is turned downward and then left stationary for a predetermined time. It is an object of the present invention to provide a new work direction control device which is devised so that the time distribution of the work direction can be arbitrarily controlled.

[0005]

In order to achieve the above-mentioned object, a work direction control apparatus according to the present invention is provided with a second and a second rotating body which is rotatable about a first axis and is not parallel to the first axis. 3 ... It also rotates about an axis, and the rotational speeds of each of a plurality of axes can be individually controlled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment shown in FIGS. 1 and 2 is a biaxial liquid removing device, in which a second shaft 3 is rotated horizontally by a bearing 4 on a vertical portion 2 of an L-shaped machine base 1. A second servomotor 7 with a speed reducer 6 is mounted on the motor base 5 while being supported freely and provided with a motor base 5 outside the vertical part 2.
Is fixed, the tip of the rotary shaft 8 of the second servomotor 7 and the outer end of the second shaft 3 are connected by a coupling 9, and the second shaft 3 is centered on the inner end of the second shaft 3. In the rotating state, the cylindrical second rotating body 10 having an open front surface is fixed, and the second rotating body 1 is attached to the upper surface of the horizontal portion 11 of the machine base 1.
The vibrator 12 is fixed in a state in which vibration is applied to 0, and the cylindrical first rotating body 14 having an open front surface is further inserted into the second rotating body 10 to move the first rotating body 14 to the above Both ends of the second rotary body 10 are oriented in a direction orthogonal to the two axes 3.
A first servomotor 19 with a speed reducer 18 is fixed to the outer surface of the second rotating body 10 while being rotatably supported by a first shaft 17 supported by bearings 15 and 16 on the peripheral wall of the first servomotor 19 The tip of the rotary shaft 20 and the outer end of the first shaft 17 are connected by a coupling 21.

The second embodiment shown in FIGS. 3 and 4 is a three-axis liquid remover, which differs from the first embodiment in the following points. That is, the cylindrical third rotating body 22 having an open front surface is inserted between the first rotating body 14 and the second rotating body 10 to move the third rotating body 22 to the first shaft 17 and the second rotating body.
The third shaft 25 is rotatably supported on the peripheral wall of the second rotating body 10 via a third shaft 25 that is non-parallel to the shaft 3 and bearings 23 and 24, and the third shaft 25 is rotationally driven by a third servomotor 27 with a speed reducer 26. And the first rotating body 14 is connected to the first shaft 17,
The first shaft 17 is rotatably supported on the peripheral wall of the third rotating body 22 via bearings 15 and 16, and the first shaft 17 is attached to the first servomotor 19.
It is designed to be rotationally driven by.

In the figure, 31 is a drainage port for draining liquid, 32 is a net lid for opening and closing, and 33 is a basket containing a work (not shown).

[0009]

The operation and operation of the workpiece direction control apparatus according to the present invention will be described based on the first embodiment. First, a cage 33 containing a work (in this case, a cap nut (not shown)) is put in the first rotating body 14 to close the mesh lid 32, and after this closing, the vibrator 12 and the The first and second servomotors 7 and 19 are operated. Then, the second servomotor 7 causes the second rotating body 10 to move.
However, at the same time, the first servomotor 19 causes the first rotating body 1
4 respectively rotate at low speed, and these first and first rotating bodies 1
The cage 33 containing the work changes its direction with the rotation of 4, 10. In this case, it is possible to control the direction of the cage 33 containing a work by adding speed control and start / stop control to the first and second servomotors 7 and 19, and any direction can be used. Therefore, it is possible to obtain a state in which the concave portion of the work such as the cap nut is always directed downward, and when the concave portion is directed downward, the vibration by the vibrator 12 is also added to completely drain the liquid in the concave portion. is there.

[0010]

EFFECT OF THE INVENTION Since the workpiece direction control device according to the present invention is configured as described above, it is possible to set the orientation of the workpiece-containing cage or the like placed in the first rotating body in any direction. It is extremely convenient to use for draining liquid from the concave part of the work such as a cap nut, or irradiating the entire surface of the work with X-rays, ultrasonic waves, heat rays, radio waves, etc. When the number of is increased, there is an advantage that it is possible to precisely and easily control the direction of the basket containing the work, and the rotation speed of each axis can be controlled individually. , It is extremely easy to use in the above speed control and time distribution control of the direction of the work, and the work is oriented in any direction as described above, so complete deliquoring, etc. Shortening, it is capable of such as lowering the rate at which scratches rub the workpiece occurs.
