Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a stage mechanism device for performing a stage effect in a theater or the like.

(Prior Art) Conventionally, there are two types of driving methods for theater hangings, a manual type and an electric type, each of which has advantages and disadvantages, and both are widely used at present.

First, the hand-operated suspension has a drawback in that the physical burden on the operator is large and it is difficult to perform the same operation repeatedly and accurately, and the counterweight must be transshipped due to the load weight. However, it is possible to perform a subtle operation in accordance with the performer's breathing.

On the other hand, since the electric type can be easily operated by a command from the operation panel, the burden on the operator is light and the same operation can be easily repeated. However, he was dissatisfied with the movement that breathed with the performers.

(Problems to be Solved by the Invention) The present invention has been made in view of the above, and aims to reduce the burden on the operator and contribute to the stage performance while utilizing the hand-operated operability. I will provide a.

[Constitution of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention detects a movement of a hauling line in a stage mechanism device that performs a stage effect using a suspended object via a hauling line. Motion detecting means, a simulated weight provided on the towline for adjusting the operational feeling of the towline, a position detecting means for detecting the position of the hanging object, and a suspended object based on output signals from the operation detecting means and the position detecting means. And a hanging mechanism control means for controlling the driving of the stage mechanism.

(Operation) In the present invention configured as described above, the movement of the tow rope having the simulated weight body for adjusting the operational feeling and the position of the suspended object are detected, and the driving of the suspended object is controlled by the detection signal. Thus, it is possible to control a suspended object that is faithful to the movement of the towline to move.

(Example) Next, an example of the present invention will be described. Fig. 1 shows a 10 tow rope
A first rotation encoder (hereinafter referred to as a rotary encoder) 3A that converts a good motion of the robot into a signal and outputs a rotation code,
A second rotary encoder 3B that detects the position of a simulated weight body (hereinafter referred to as a dummy weight) 11 that adjusts the operation feeling of 10 and an operation indicator rod (hereinafter referred to as a baton) 1 and converts the signal to output a rotation code. And a servo driver 8 controlled by output signals from the rotary encoders 3A and 3B, and an equilibrium weight (hereinafter referred to as a counter) moved up and down by a rotary drum (hereinafter referred to as a traction drum) 5 driven by the servo driver 8. (Referred to as a weight) 12.

That is, reference numeral 1 denotes a baton, which is suspended by a wire 15 via a pulley 4 from a traction drum 5 and a counterweight 12 from a corner. Reference numeral 10 denotes a towing line, which is attached in a loop between the lower part of the rope and the pulley 4 of the rope base. In addition, a dummy weight 11 for adjusting the operational feeling is attached to the guide line 10.

Reference numeral 3 denotes a rotary encoder, one of which is attached to the rotary shaft of the cable winder 2 on the side for detecting the position of the baton 1, and its output signal is input to the control panel 9. The other is attached to the rotating shaft of the pulley 4 of a dumbbell or a rope for detecting the position and speed of the guide line 10, and the output signal is input to the control panel 9.

The servo motor 6 is connected to the traction drum 5, and its control signal line is connected to a control panel 9 via a servo driver 8 together with a resolver signal line 7 attached to the axis of the servo motor 6.

Reference numeral 13 denotes a rope indicator light, and reference numeral 14 denotes an operation panel, all of which are connected to the control panel 9.

 Next, the operation of the present invention will be described.

When the operator of the rope turns on the rope indicator light 13 according to the instruction from the control panel 9 and pulls the pull rope 10, the pulley 4 is turned, and the rotary encoder 3 responds to the rotation speed. When a signal is input to the control panel 9 and the towing line 10 stops,
The signal of the rotary encoder 3 is obtained.

The control panel 6 outputs an operation command, a speed signal, and a stop command to the servo driver 8 based on this signal. The servo motor 6 drives the traction drum 5 based on this command to operate the baton 1. At this time, the position and speed of the baton 1 are detected by the rotary encoder 3B and the resolver 7 attached to the cable winder 2 and input to the control panel 9. The control panel 9 compares this signal with the position and speed signals of the hauling line, and controls the baton 1 to move faithfully in accordance with the movement of the hauling line.

The operation panel 14 outputs a switching instruction to operate the baton 1 simultaneously with the operation of the towing line, or to temporarily store only the signal of the towing line in the control panel, and to instruct the operator when to pull the line. An instruction to turn on the rope indicator light 13 is given.

As described above, the stage mechanism device of the present invention is configured to mechanically separate the actual load from the actual load and to electrically detect the operation speed of the tow rope and the stop position in order to reduce the physical burden during the manual operation. This signal is used to drive the electric suspended object, and the operator does not need to move the ropes in accordance with the operation sequence of the suspended object. The operation signal input to the control panel is
If necessary, it can be edited and used repeatedly in the control panel. On the other hand, the electric hanging can be operated simultaneously with the manual operation.

[Effects of the Invention] According to the present invention, it is possible to operate a subtle effect expression on an electric suspension without imposing a physical burden on a guide operator.
