Both rotating plates 11 and 12
Requires that one rotating plate (for example, 11) be horizontal and the other rotating plate (12) be vertical, so that each can be rotated separately. The passive members 15 and 16 are the rotating plate 1
It receives the rotational driving force input to 1, 1 and 12, and is combined with the driving members 17 and 18 for input to form driving force transmitting means.

There are various mechanisms as examples of the driving force transmitting means, and any mechanism can be applied to the present apparatus. The embodiment shows an example using a chain drive mechanism and a gear drive mechanism.

The chain drive mechanism is illustrated in FIGS. In this mechanism, the passive members 15 and 16 have a chain 20 stretched along an arcuate surface 19 about the rotation axis A, and one end 21 of the chain 20 is connected to the arcuate surface 1.
The other end 22 is attached to the inner end of the arcuate surfaces 19,19. The driving members 17 and 18 are gears 23 and 23 meshing with the chains 20 and 20, respectively. The driving members 17 and 18 are rotated by a rotation output of a driving source 24 indicated by a motor, and are connected to the chain 20 via a transmission system.

The gear drive mechanism is illustrated in FIGS. In this mechanism, the passive members 15 and 16 are large gears 25 provided along an arcuate surface 19 centered on the rotation axis A. The corresponding driving members 17, 18 are small gears 26, 26 meshing with the respective large gears 25, 25, and are driven through a known transmission system by the rotation output of a driving source 27 indicated by a similar motor. You.

It is desirable that the driving sources 24 and 27 have a brake, a motor with a speed reducer, or a function equivalent thereto. The above two rotating plates together one of the rotating plate are the other rotating plate positionable at right angles to, two rotary plates 11, 12 further maintains orthogonality relations above them to rotatable, the transmission mechanism 28 for transmitting the rotational force applied to the one rotating plate by rotation in the other rotating plate two rotating plates 11, 12
It is provided between them. The transmission mechanism 28 can be said to be a means for integrating the two rotating plates 11 and 12 so that the respective surfaces of the two rotating plates are in a right-angled positional relationship, which are indicated by chain lines in FIG. 1 or FIG. .

In the illustrated embodiment, when the rotary plates 11 and 12 are in an orthogonal relationship, the larger angle (dominant angle) of the conjugate angle about the rotation axis A is 270 degrees. ,
The angle of the fan-shaped rotating members 29, 29 having the arc-shaped surfaces 19, 19 of approximately 135 degrees, which is obtained by dividing this into two, is provided, and a transmission mechanism 28 is provided at each inner end of the rotating members 29, 29. . The size (angle) of the rotating member 29 is 135
The degree is not limited, and it is sufficient that the total is 270 degrees or more. A chain 20 is stretched on the arc-shaped surface 19 of the rotating member 29 by a chain drive mechanism, and a tooth row of a large gear 25 is provided by a gear drive mechanism.

The transmission mechanism 28 is used to rotate the rotating members 29, 29, which rotate while maintaining the parallel relationship, as one body.
So that they are engaged with each other. For example, a hole is formed as an engaging portion in one rotating member, and a piston is projected as an engaging member from a cylinder attached to the other rotating member,
The structure that engages the hole is suitable for this purpose.

In the embodiment, as shown in FIG. 7, one rotating member (29-1) is provided with an engaging portion 30, and the other rotating member (29-2) is provided with the same. An engaging member 31 capable of engaging with the engaging portion 30 is pivotally supported, and the engaging member 31 can be protruded and retracted by a reciprocating device 33 such as a pneumatic, hydraulic or electromagnetic cylinder. Reference numeral 32 denotes an arm provided on the engaging member 31, which causes the engaging member 31 to protrude and retract from the engaging portion 30 by expansion and contraction of the piston 34. The operating part can be covered by a cover 35.

When the apparatus 10 is not in operation, FIGS.
The two rotating plates 11 and 12 can be arranged in a horizontal state shown by a solid line in FIG.
1) is placed horizontally and the other rotating plate (also 12) is placed vertically, and the preparation is completed. The vertical rotation of the other rotary plate 12 can be performed by the driving force transmitting means. Thereafter, the heavy object W is placed on the horizontal rotating plate 11 so that the heavy object W contacts the upright rotating plate 12 at this time. See FIG.

Next, the driving members 17 and 18 are operated.
Before that, the transmission member 28 is actuated to rotate the rotating plates 11 and 12.
In a state where they can be rotated together. Drive member 17, 1
By the operation of 8, the horizontal rotating plate 11 and the vertical rotating plate 12 start rotating integrally. At this time, since almost all the load of the heavy object W is applied to the horizontal rotating plate 11, a large load is applied to the driving member 17 on one side, but in the present invention, both rotating plates 11, 12 are integrated. Due to the rotation, the driving member 18 on the other side also bears the load equally.

As the rotation proceeds, the magnitude of the load applied to both rotating plates 11 and 12 is reversed at the intermediate point, and a greater load is applied to the other rotating plate 12 this time. FIG.
See FIGS. However, in this case also, both drive members 1
7 and 18 share the torque equally, and both rotating plates 11 and 12
And the surface in contact with the other rotating plate 12 becomes the lower surface, and the transfer to the heavy object W is completed. FIG. 14 shows a state in which the heavy object W has been transferred to the other rotating plate 12 and rotated 90 degrees.

[0018]

Since the present invention is constructed and operates as described above, two driving devices such as motors assist each other to rotate a heavy object.
Basically, the power can be used more effectively than in the case where each of the driving devices has to bear the full load of a heavy object, and the output of the driving device can be reduced, the shaft, the bearing, and the power transmission system can be used. Such members can be used for a lower load, and the effect is achieved that the economy is remarkably improved.
