[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention uses each tilt drive device to separately control the tilted floors on each adjacent floor frame as desired. In a stage mechanism equipment equipped with a plurality of floor mechanisms set at an angle of inclination, the stage mechanism includes an elevation position detection means for detecting an elevation position of a floor frame in the first floor mechanism, and an inclination angle of the inclined floor is set. a tilt angle setting means; a tilt angle detecting means for detecting the tilt angle of the tilted floor; an output of the tilt angle setting means and an output of the tilt angle detecting means are compared, and a tilting operation command is issued until the two river forces match; Comparing means applied to the tilting drive device, and rear elevation position setting means for determining the elevation position of the floor frame in the second floor mechanism from the output of the elevation position detection means and the output of the inclination angle detection means. In this configuration, the elevation position of the floor frame determined by this rear elevation position setting means is used as the elevation position setting value of the floor frame in the second floor mechanism.

Control the lifting and lowering position of the floor frame until it reaches zero. On the other hand, the tilt control of the tilted floor is performed by comparing the set angle of the tilt angle setting means with the tilt angle of the tilted floor detected by the tilt angle detection means, and increasing the tilt angle of the tilted floor until the two angles match. control. After determining the inclination height from the inclination angle of the inclination angle detection means obtained as described above and the length of the inclined floor, the next floor mechanism is determined from this inclination height and the output of the lifting position detection means. Find the elevation position that will serve as the stage reference plane and set the floor frame at that position. By performing similar processing for the next floor mechanism and subsequent ones, for example, a stage having an inclined surface at a predetermined angle is constructed by combining a plurality of inclined floors.

(Example) Hereinafter, an example of the apparatus of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram showing the configuration of a floor mechanism control device, and FIG. 2 is a diagram showing the configuration of the floor mechanism, which is stage mechanism equipment. In these figures, the same parts as in FIG. 4 are given the same reference numerals, and detailed explanation thereof will be omitted.

First, regarding the floor mechanism, it has almost the same configuration as the conventional floor mechanism, and the main difference is that, as shown in FIG. □.

The reason is that...

Next, the control portion of the first floor mechanism 10 in the floor mechanism control device includes a lifting position detection counter 41 that counts the output pulse signal of the encoder 17 as shown in FIG. The elevating position setting unit 42 sets the elevating position setting value of the elevating position setting unit 42 and the actual elevating position of the floor frame 15 determined by the elevating position detection counter 41, and issues an elevating operation command until the deviation becomes zero. and a comparator circuit 44 that supplies the lift drive device 43 with a comparison circuit 44, which sets the floor frame 15 of the first floor mechanism 10 to a predetermined lift position setting value.

Further, the control portion of the first floor mechanism 10 includes an encoder 3.
1. A tilt angle detection counter 46 detects the tilt angle of the tilted floor 18 by counting output pulse signals of the tilted floor 18.
a comparator circuit that compares the output of these counters 46 with the output of the tilt angle setting unit 47 and introduces a tilting operation command to the tilting drive device 19 until the angular deviation becomes zero. In addition to the inclination angle control means 49 consisting of 48 and the like, a rear elevation position setting means 51 is provided on the output side of the two detection counters 41 and 46.

This rear elevation position setting means 51 includes a slope height calculating section 52 which calculates the slope height from the output θ1 of the slope angle detection counter 46, and an output g of the position detection counter 41. and the slope height g obtained by the slope height calculating section 52, and an elevator position setting section 53 that calculates the next elevator position setting value of the floor frame 25 by adding the slope height g obtained by the slope height calculation section 52.

Note that the configuration of the control part in the second floor mechanism 20 is the same as that in the first floor mechanism 20.
The control portion is exactly the same as the control portion of the floor mechanism 10, and therefore, the same portions are given the same numbers with a dash “′” and detailed explanation thereof will be omitted.

Next, the operation of the above device will be explained. Now, when the operation command is issued, the rack type lifting device 1 is moved by the operation of the electric motor 11.
2 raises and lowers the rack columns 13 and 14, and the vertical position of the rack column 13 at this time, that is, the vertical distance is detected by the vertical position detection counter 41 via the rack pinion 16 and the encoder 17. Then, the comparison circuit 44 compares the elevation position obtained by the elevation position detection counter 41 with the elevation position setting value set in advance in the elevation position setting section 42,
The elevating operation command is output until both values match, and the elevating drive device 43 supplies electric power for elevating the electric motor 11 . Then, the output of the elevation position detection counter 41 and the elevation position setting section 4
When the output of motor 2 matches, a stop command is output and motor 1

On the other hand, the tilt angle of the tilted floor 18 is controlled by the encoder 31. Tilt angle counter 46 via
and sends it to the comparison circuit 48. This comparison circuit 48
compares the tilt angle detected by the tilt angle detection counter 46 with the tilt angle setting value set in advance in the tilt angle setting section 47, and similarly outputs a tilt operation command until both values match, and performs tilt drive. The inclination angle of the inclined floor 18 is increased through the device 19. When both values match, a stop command is output and the tilt drive device 19 is stopped. As a result, this operation moves the inclined floor 18 to the inclination angle setting value θ1
Can be set to

At this time, since the inclination angle detected by the inclination angle detection counter 46 is introduced into the inclination height calculation unit 52, the inclination height calculation unit 52 makes the length Wl of the inclined floor 18 known, and the inclination angle After calculating the slope height p of the slope floor 18 using θ1, it is sent to the elevation position setting section 53.

This elevation position setting section 53 determines the position p of the floor frame 15.

The slope height 11 of the slope floor 18 is added to
o +il i ) is set as the elevation position setting value of the next floor frame 25, and is supplied to the comparison circuit 44' of the next floor mechanism 20. Therefore, this comparison circuit 44' compares the lifting position set value with the lifting position of the floor frame 25 obtained from the lifting position detection counter 41', controls the electric motor 21 so that both values match, and is raised and lowered to the position (Io+ff+). Thereafter, the same process is repeated for the rear floor mechanisms 20, . . . , and stages are successively constructed at desired elevation positions and at predetermined inclination angles.

Therefore, according to the configuration of the embodiment as described above, the lifting position is set in advance in the lifting position setting section 42 of the first floor mechanism 10, and each floor mechanism 10.20. ... inclination angle setting section 4
By setting the inclination angle to 6.46'..., not only can the floor frame 15 of the first floor mechanism 10 be quickly set to the desired lifting position, but also the rear floor mechanisms 20,...
The floor frames 25, . . . of the floor frames 25, . The tilt angle can be set to the desired angle. Therefore, for example, by setting the inclination angle of the inclination angle setting parts 46, 46', etc. arbitrarily in advance, it is possible to freely set different inclination angles for each inclined floor 18, 28, . Stage equipment can be constructed with great flexibility.

In the above embodiment, the setting values of the elevation position setting section 42 and the inclination angle setting section 46, 46', etc. are considered to be fixed, but if the program data format is changed sequentially according to the passage of time, each setting value can be set as fixed. The floor mechanisms 10, 20, . . . can be changed continuously. Furthermore, it goes without saying that by setting the respective inclination angle setting parts 46, 46', . . . to a desired inclination angle, for example, a zero inclination angle, a stepped stage as shown in FIG. Furthermore, although the rear position setting unit 53 performs addition processing, subtraction processing is performed when, for example, each inclined floor 18, 28, . . . is set in an inclination direction opposite to that shown in FIG. shall be taken as a thing. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.
