It is desirable that these panels be arranged at a position where the operator (operator) can easily operate or be in an easy-to-operate state. However, the physique is different for each worker and the operation state changes, so the panels can be moved to a desired position or in a desired direction according to the physique difference or change in the operation state. It is necessary to change.

  In view of this, there has been proposed an apparatus having a mechanism that can skillfully and easily change the position and orientation of the panels according to the difference in the physique of the worker and the change in the operation state (for example, Patent Documents). 1).

  In Patent Document 1, the panels move up and down by the expansion and contraction of the support, the panels rotate with respect to the support by the rotation of the movable body constituting the support with respect to the support shaft, and have an axis in the radial direction of the support shaft. Thus, the mechanism is such that the elevation angle / the depression angle of the panels changes by the rotation of the rotation shaft assembled to the support column. Here, any operation can be manually performed by the operator.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 2 is a front view of a panel mounting stand in which an embodiment of the panel automatic lifting apparatus of the present invention is incorporated, and FIG. 3 is a side view thereof.

  The panel mounting stand shown in FIGS. 2 and 3 includes a base 11 provided with a support portion 12 at a lower part, a fixed cylinder 13 fixed to the upper part of the base 11 and having a cylindrical shape with a square cross section, and a fixed cylinder. 13 is fixed to the upper part of the sliding cylinder 14, the operating panel 21, and the sliding cylinder 14, which has a rectangular cylindrical shape that can be slid along the inner side surface by a mechanism described later. A first rotation mechanism unit 15 having a mechanism for holding the operation panel 21 rotatably with respect to the axis and holding the operation panel 21 with respect to a rotation axis perpendicular to the vertical axis; a display panel 31; The display panel 31 is fixed to the upper part of the rotation mechanism 15 so as to be rotatable with respect to the vertical axis of the entire stand, and the display panel 31 is rotatably held with respect to a rotation axis perpendicular to the vertical axis. Second time with mechanism It has a mechanism section 16, the. Further, the operation panel 21 and the display panel 31 are connected to the first rotation mechanism unit 15 and the second rotation mechanism unit 16 via the first rotation shaft 17 and the second rotation shaft 18, respectively. . Further, the operation panel 21 and the display panel 31 are respectively provided with an operation panel gripping part 211 and a display panel gripping part 311 for manually turning / rotating them.

  It is preferable that the first rotation mechanism unit 15 and the second rotation mechanism unit 16 include a mechanism for fixing / relaxing the turning / rotation movement of the operation panel 21 and the display panel 31. The lever for that is shown in the figure.

  In FIG. 3, the operation panel 21 and the display panel 31 are rotated about the first rotation shaft 17 and the second rotation shaft 18, respectively, so that the operation panel 21 and the display panel 31 face upward. This is indicated by a virtual line.

  In the present embodiment, the operation panel 21 and the display panel 31 are exemplified as the panels, but the type and number are not limited thereto. Further, the positional relationship between them is not limited to this.

  FIG. 1 is a diagram showing a main configuration of an embodiment of an automatic lifting apparatus for panels according to the present invention, in which FIG. 1 (a) is a sectional view taken from the side, and FIG. It is sectional drawing along the bb line in the figure (a).

  The vertical movement of the operation panel 21 and the display panel 31 in the vertical direction is realized by sliding the sliding cylinder 14 with respect to the fixed cylinder 13. Specifically, the pinion 2 attached to the rotating shaft of the motor 1 (for example, a three-phase motor) mounted on the fixed base 4 meshes with the rack 3 fixed to the inner wall surface of the sliding cylinder 14. It has a configuration. Thereby, the mechanism in which the rotational motion of the motor 1 is converted into the linear motion of the rack 3 in the vertical direction is configured. The lower end of the fixed base 4 is fixed to the bottom of the base 11 although not shown. In addition, power is supplied to the motor 1 via the terminal block 6, and an elevation control signal from the operation box 5 is supplied to the motor 1.

  With this configuration, when the operator depresses the raising switch or the lowering switch of the operation box 5, the raising / lowering control signal from the operation box 5 is supplied to the motor 1 via the terminal block 6, and the motor 1 is accordingly turned on. Thus, the sliding cylinder 14 slides relative to the fixed cylinder 13. In addition, it is suitable to provide a limiter at each of the sliding upper end position and the sliding lower end position of the sliding cylinder 14.

Next, the operation of the operator and the operation of the apparatus accompanying it will be described.
The worker presses the up switch or the down switch of the operation box 5 according to the work to be performed (for example, to operate the operation panel 21 or to confirm the display on the display panel 31 accurately). When the raising switch is pressed, the part above the sliding cylinder 14 rises with respect to the part below the fixed cylinder 13, so that the operation panel 21 and the display panel 31 rise for the operator. On the other hand, when the down switch is pressed, the opposite is true. Note that the control that the motor 1 rotates while each switch is pressed is typical, but the present invention is not limited to this.

  Next, the operator operates the levers of the first rotation mechanism unit 15 and / or the second rotation mechanism unit 16 as necessary to release the fixation, and the operation panel 21 and / or the display panel 31 are moved. Rotate and / or rotate to bring it to the desired position and / or orientation and fix them by operating the lever again.

  In the above-described embodiment, the rack and pinion mechanism is employed as a mechanism for sliding the sliding cylinder 14 with respect to the fixed cylinder 13. The mechanism of this will also come to mind.

  As described above, according to the above-described embodiment of the panel automatic lifting apparatus of the present invention, the operation panel 21 and the display panel 31 can be easily lifted and lowered in the vertical direction.

  The automatic lifting / lowering device for panels according to the present invention can be employed for raising / lowering an operation panel or a display panel for performing an operation control operation on a machine tool and displaying an operation state thereof.
