If the target position has been reached, a target position arrival determination means for giving a determination command to the moving distance reversing means, an amplitude operation number setting means for setting the number of repeated operations between the starting point and the target position, and It is determined whether or not the number of times the target position arrival command is input every time the target position is reached by the target position arrival determination means matches the number of repeated operations set in the amplitude operation number setting means. Then, the control device operating means is provided with an operation end command to stop the operation of the hanging equipment, and the inversion number determining means is provided.

Therefore, in the hanging operation control device for a stage apparatus according to the second aspect of the invention, when the hanging device controlled according to the set speed and the moving distance is driven to the target position, the moving distance is reversed. In this way, the vehicle is driven to the next target position, and when it is determined that the number of repeated operations has reached the preset number of repeated operations, the operation of the suspended equipment is terminated by the operation end command output. , It is possible to perform the repetitive operation of repeating the movement of the suspended object many times with a small number of settings and a simple operation.

According to a third aspect of the invention, in the invention according to the first aspect, the amplitude operation number setting means for setting the number of repetitive operations between the starting point and the target position, and the target position arrival determining means set the target. It is determined whether or not the number of times the target position arrival command is input each time the position is reached matches the number of repeated operations set in the amplitude operation number setting means. If they match, an operation end command is output. The control device operating means stops the operation of the hanging device when the operation end command is input before any deviation of the inversion number determining means or the operating time determining means.

Therefore, in the hanging operation control device for a stage apparatus according to the third aspect of the invention, when the hanging device controlled according to the set speed and the moving distance is driven to the target position, the moving distance is reversed. Then, it is operated to the next target position, and it is judged that the number of repeated operation has reached the preset number of repeated operation, or the operation time is set to the preset operation duration after the operation is started. When it is determined that the object has been reached, the operation of the hanging equipment is stopped by the operation end command that is output somehow earlier, so the setting of the setting is small and the operation of moving the hanging object can be repeated many times. Repeated operation can be repeated.

In FIG. 1, 1 is a speed setting means for setting a moving speed of a hanging object, 2 is a moving distance setting means for setting a moving distance from a starting point of the hanging object to a target position, and 3 is a moving position of the hanging object. In the position detecting means for detecting, as the position detecting means 3, for example, an absolute encoder or a pulse generator is used.

Further, 4 is a current position calculation means for obtaining the current position based on the position data 18 detected by the position detection means 3, and 10 is the movement distance coordinate 17 set in the movement distance setting means 2. The moving distance reversing means 5 subtracts the current position coordinates 19 obtained by the current position calculating means 4 from the new moving distance coordinates 25 output from the moving distance reversing means 10 by the subtractor 9 and inputs the deviation 24. It is a target position arrival determining means.

The target position arrival determining means 5 inputs the reversal command 20 to the moving distance reversing means 10 when the deviation 24 between the current position coordinate 19 and the new moving distance coordinate 25 becomes close to zero, and also the moving distance. The reversing means 10 reverses the moving distance coordinates set by the moving distance setting means 2 when the reversing command 20 is inputted from the target position arrival judging means 5, and gives them to the subtractor 9 as new moving distance coordinates.

Further, 7 is the speed data 1 set by the speed setting means 1 in accordance with the deviation 24 inputted from the subtractor 9.
Speed reference value data 23 for driving a suspended object based on 6
Is output to the control device operating means, 8 is the control device operating means 7
It is a speed reference value output means for giving a speed reference value to a control unit of a variable speed electric motor which drives a suspension device (not shown) which is a control target based on the speed reference value data 23 inputted from the above.

On the other hand, 11 is the operation start command input by the operator, 12 is the operation continuation time setting means for setting the operation continuation time, 13 is the operation start command 26 and the operation time data 27, and reaches the operation continuation time. Then, the driving time determination means for outputting the driving end signal 28, and the driving end output means 6 for giving the driving end signal 22 to the control device driving means 7 when the driving end signal 28 is inputted from the driving time judgment means 13.

In this way, the hanging device is operated by the control device operating means 7 until the deviation becomes sufficiently small, and eventually stops when the hanging device moves within the allowable range of the target position, at which time the target position is reached. A reversing instruction 20 is given from the judging means 5 to the moving distance reversing means 10.

Then, in this moving distance reversing means 10,
The moving distance coordinate is input to the subtractor 9 as a new moving distance coordinate which is inverted. The subtractor 9 obtains a deviation 24 between the new moving distance coordinate and the current position coordinate 19 input from the current position calculating means 4 and gives it to the control device operating means 7.

In the control device operating means 7, when the deviation is larger than a certain value as described above, the hanging device is operated toward the next target position at a speed commensurate with the deviation, and the deviation is sufficiently small. Then, when the suspended equipment moves within the allowable range of the target position, it will stop.

In such repetitive operation, the above operation is repeated until the time set by the operation duration setting means 12 is reached. Then, when it is determined by the operation time determination means 13 that the operation duration time has been reached and the operation end signal 28 is given to the operation end output means 6, the operation end output means 6
