It includes.

When the raising or lowering of the device film 14 is manipulated during the performance, the barton 10 is raised or lowered by the operation of the driving unit 50 to thereby raise or lower the device film 14.

When the device film 14 is raised, the wire member 12 is pulled by the drive unit 50, and the wire member 12 pulled by the drive unit 50 is wound around the storage unit 70.

The wire member 12 pulled by the ascending distance of the barton 10 is not wound around the driving unit 50, but is wound around the storage unit 70 through the driving unit 50, so that the storage of the wire member 12 may be accommodated in the driving unit 50. Since no space is required, the size of the driving unit 50 is reduced.

The driving unit 50 is rotatably installed on the support 30 installed in the upper part of the performance hall, and the drum 52 on which the wire member 12 is wound, and the first motor connected to the rotation shaft 54 of the drum 52. 56).

The end of the wire member 12 wound on the circumferential surface of the drum 52 is connected to the storage unit 70, so that the wire member 12 wound while being rotated along the circumferential surface of the drum 52 rotates the drum 52. After passing through the storage unit 70.

As described above, since the wire member 12 is not wound and stored in the drum 52, the length of the drum 52 is moved to the storage part 70 after being wound 1 to 3 turns along the circumferential surface of the drum 52. Can be formed relatively short.

Barton 10 is arranged long in the left and right direction and the barton 10 is connected to the barton 10 to maintain the spacing so that the plurality of wire members 12 are spaced in parallel to rise or fall, a plurality of wire members Since 12 is wound on one drum 52 at the same time, it is difficult to reduce the length of the drum 52.

In this embodiment, since the wire member 12 pulled by the drum 52 is not wound on the drum 52 but is wound on the storage unit 70 through the drum 52, the drum 52 pulling the wire member 12. ) Length can be easily reduced.

In addition, the driving unit 50 includes a load cell 58 installed on the rotation shaft 54, a drive 59 controlling the first motor 56 according to a signal transmitted from the load cell 58, and a load cell 58. The controller 60 may further include a controller 60 for determining a transmitted electrical signal and transmitting a driving signal to the drive 59.

Therefore, when the operator manipulates the movement of the barton 10 and judges the load on the rotating shaft 54 and exceeds the set value, the operation of the driving unit 50 and the storage unit 70 does not proceed and the output unit 68 does not proceed. Emergency signal is output.

The storage unit 70 has a wheel drum 72 having an end of the wire member 12 fixed thereto, the wire members 12 stacked and wound, and a second motor connected to the drive shaft 76 of the wheel drum 72. 74).

Since the second motor 74 is driven simultaneously with the first motor 56 and driven in the same direction, the wire member 12 wound around the drum 52 and then moved to the storage part 70 is wound on the wheel drum 72. Let's do it.

The wire member 12 wound on the wheel drum 72 is laminated and wound in the space between the wheel parts 82a, 84a, and 86a, which will be described later, so that the curvature of the wound wire member 12 is gradually increased, and the wheel parts 82a, In the space between 84a and 86a).

Since a plurality of wheels 82a, 84a, 86a are continuously disposed on the circumferential surface of the wheel drum 72, a plurality of wire members 12 connected to the barton 10 are respectively provided with wheels 82a, 84a, It is laminated and wound in the space between 86a).

Therefore, the plurality of wire members 12 can be wound simultaneously without increasing the length of the wheel drum 72.

The wheel drum 72 is a unit drum having a wheel portion 82a and a fixed shaft 82c formed therein and a drum body 82 installed on the drive shaft 76, and a wheel portion 84a formed on the fixed shaft 82c. And a finishing drum 86 formed with the wheel portion 86a and installed on the fixed shaft 82c to restrain the unit drum 84.

A plurality of unit drums 84 in which the hole portion is formed with the wheel portion 84a are continuously inserted into the fixed shaft 82c formed at the center of the drum body 82, and the wheel portion 86a is provided at the end of the fixed shaft 82c. Combining the formed finish drum (86) to assemble the wheel drum (72).

Steps 82b and 84b are formed in the drum body 82 and the unit drum 84 to form a space in which the wire members 12 are stacked between the wheel parts 82a, 84a, and 86a. , 86a) is formed between the spaces.

Since the space portion formed between the wheel portions 82a, 84a and 86a is formed in a small amount compared to the thickness of the wire member 12, the next wire member 12 is inserted after the one wire member 12 is wound and wound. When inserted between the 82a, 84a, and 86a, it is wound while being stacked on the upper side of the wire member 12 inserted before.

Therefore, when the winding of the wire member 12 is made continuously, the curvature of the wound wire member 12 is increased step by step.

In addition, the support 30 is provided with a guide member 32 through which the wire member 12 penetrates so that the wire member 12 is guided into the space between the wheel parts 82a, 84a, and 86a.

The support 30 has a pair of supports 30 installed at the front and rear of the drum 52 and the wheel drum 72, and connects the pair of supports 30 to the left and right to face the wheel drum 72. The guide member 32 is installed long in the direction.

The guide member 32 has a hole portion formed at a position opposite to the space portion between the wheel portions 82a, 84a, and 86a, so that when the wire member 12 is inserted into the hole portion, the wire member 12 is wheel portions 82a, 84a, 86a. Are arranged opposite to the space between them.

The wire member 12 pulled by the drum 52 is laminated while being inserted into the space between the wheel parts 82a, 84a, 86a through the guide member 32, and thus the wire member 12 by the guide member 32. Is moved in the correct direction toward the space between the wheel portions 82a, 84a, 86a.

In addition, since the guide roller 34 which contacts the wheel parts 82a, 84a, 86a is rotatably installed in the support 30, the wire member 12 laminated in the space between the wheel parts 82a, 84a, 86a is wheel part. It is possible to prevent the departure from the outside (82a, 84a, 86a).

The second motor 74 is torque controlled by the controller 60 such that the wheel drum 72 is rotated while maintaining a constant torque.

When the barton 10 is raised or lowered, the wire member 12 must be pulled or released at the same speed to move the barton 10 at the same speed from the beginning to the end of operation. Since the curvature of the wire member 12 is changed in stages, the winding speed is changed while performing the winding operation of the second motor 74.

Since the wire member 12 wound on the drum 52 is not laminated and always maintains the same curvature and is wound to the drum drum 72 after being wound on the drum 52, the first motor 56 is always driven at the same speed. The speed of pulling or unwinding the wire member 12 is the same.

On the other hand, since the curvature of the wire member 12 wound on the wheel drum 72 is changed in stages, the power of the second motor 74 is changed and controlled so that the pulling force of the wire member 12 remains the same. do.

Particularly, when the wire member 12 is released and the barton 10 is lowered, the force for pulling the wire member 12 by the second motor 74 is maintained uniformly, thereby preventing the barton 10 from falling rapidly. do.

Therefore, the second motor 74 and the wheel drum 72 serve as an electronic weight to prevent the abrupt fall of the barton 10.

Looking at the control method of the lifting device for a concert hall according to an embodiment of the present invention configured as described above are as follows.

When a device such as the device film 14 is installed in the barton 10 for the installation of a performance hall, tension is generated in the wire member 12 having one end connected to the barton 10.

The tension generated in the wire member 12 is transmitted to the rotating shaft 54 through the drum 52 to which the other end of the wire member 12 is wound.

When the barton 10 driving signal is input by the operator's manipulation or driving of the controller 60 during the performance, the first motor 56 and the second motor 74 are driven, and the load applied to the rotating shaft 54 is Fine deformation is caused in the rotating shaft 54.

The deformation of the rotary shaft 54 is detected by the load cell 58 and output as a voltage waveform. The minute voltage waveform output from the load cell 58 is transmitted to the amplifier 62 and amplified.

The voltage waveform amplified by the amplifier 62 is converted into a digital value through the A / D converter 64, and the digital value is transferred to the drive 59 so that the first motor 56 is driven by the drive 59. The rotation speed of is determined.

The digital value generated by the A / D converter 64 may be output by the output unit 68. When the digital value exceeds the set value, the first motor 56 and the second motor 74 are stopped. In step S40, the emergency signal is output.

When the digital value produced by the A / D converter 64 is less than or equal to the set value, normal operation proceeds, and the wire member 12 that is pulled by the driving of the first motor 56 and the second motor 74 is a drum ( After winding around the periphery of 52, it is wound around the wheel drum 72.

The wire member 12 pulled by the drum 52 is wound while being laminated in the space between the wheel parts 82a, 84a and 86a and the wheel parts 82a, 84a and 86a through the hole of the guide member 32, The wire member 12 stacked between the wheel parts 82a, 84a, 86a and the wheel parts 82a, 84a, 86a is wheel part 82a by the guide roller 34 which rotates while contacting the wheel parts 82a, 84a, 86a. , 84a, 86a) are prevented from escaping outward.

The first motor 56 of the drive unit 50 is driven at the same speed, and the second motor 74 of the storage unit 70 is controlled to maintain a constant torque.

As the diameter increases, the diameter of the wheel drum 72 is increased.

Therefore, the second motor 74 is controlled to pull the wire member 12 with the same torque while the drive speed is gradually lowered when the wire member 12 is wound.

Initially, when the operation of lowering the barton 10 is started, the driving speed of the second motor 74 is driven slowly, and the driving speed of the second motor 74 is increased step by step, so that the first motor just before the operation is finished. It becomes similar to the driving speed of 56.

Of course, even when the barton 10 is lowered, since the driving speed is increased step by step to maintain the same torque, the second motor 74 serves as an electronic weight to prevent the barton 10 from falling sharply.

As described above, in order to control the wheel drum 72 to maintain the same torque, the torque sensor 78 is preferably installed on the drive shaft 76 on which the wheel drum 72 is installed.
