Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention provides a large number of shafts rotatably mounted on a rotary base plate that is rotatably supported, and the shafts are placed in an operating position each time the rotary base plate is rotationally moved. The present invention relates to a multi-axis drive transmission device in which rotation of a drive shaft is transmitted to the shaft via an electromagnetic clutch when the shaft is stopped at a position corresponding to the drive unit.

[0002]

2. Description of the Related Art Conventionally, a large number of shafts axially supported on a rotary table or the like are equipped with a motor for each shaft or a single shaft when the shafts for winding continuous paper or the like are rotated. All of them were driven at once by gears, belts, etc.

[0003]

As described above, in order to give a drive to each of the plurality of axes arranged on the rotary base, it is wasteful and uneconomical to provide a motor for each axis as described above. Rotating the shaft with one motor as in the latter case transmits the rotation to all. Therefore, there is an inconvenience such as danger during work because the unnecessary shaft is rotated. Further, conventionally, in the case of multiple axes, it was not possible to perform work by different rotations.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances in order to solve this problem, and a plurality of shafts arranged on a rotary table to be rotated or moved are each rotatable. Along with supporting, a drive shaft corresponding to the shaft is arranged at one position on the frame of the path on which the rotary base moves.
An electromagnetic clutch mechanism is provided, and an engaging portion for clamping with a clamp mechanism provided on the fixed side is further provided on the rotary base. Further, the clamp mechanism is linked to the electromagnetic clutch mechanism to clamp the rotary base and drive shaft. The invention provides a transmission device adapted to transmit the rotation of the shaft to another shaft.

[0005]

According to the present invention, the rotary base 1 whose central portion is attached to the rotary shaft 4 supported by the bearing body 3 of the frame 2 is sequentially attached to the plurality of winding shafts 5 arranged on the rotary base 1, for example. When winding continuous paper, etc., you want to wind continuous paper on the turntable 1
The rotary base 1 is driven and rotated by a motor or the like so that it becomes the same axis as the drive shaft 12 set to the frame 2 side, and when it comes to the same axis position, it is detected by a sensor. The valve 21 operates to advance the wedge piece 17 guided by the guide member 20 to engage the wedge piece 17 with the notch concave portion 18 of the locking piece 19 on the rotary base 1 at the corresponding position. When the rotary base 1 is stopped after confirming the above, the sensor operates due to this engagement, and when the electromagnetic clutch A is energized, an electromagnetic force acts to resist the disc 10 corresponding to the friction plate 13 against the leaf spring 9. To adsorb. At this time, the drive shaft 12 to which the friction plate 13 is attached is rotated by the drive from the drive unit, and this rotation rotates the flange 8a of the transmission member 8 via the disc 10 and the bolt 11, and further rotates the winding shaft 5. And wind the continuous paper.

Next, when the winding shaft 5 is wound by a certain amount, the detection piece 8b provided on the flange 8a of the transmission member 8 detects it by the corresponding sensor 23, and this detection energizes the coil 14 of the electromagnetic clutch A. By stopping and releasing the attraction force of the disc 10, the disc 10 is separated from the friction plate 13 by the leaf spring 9 and the rotation transmission is cut off. Simultaneously with the interruption of the transmission, the wedge piece 17 engaged with the notch recess 18 of the locking piece 19 is disengaged from the notch recess 18 by disconnecting the energization of the solenoid, and is withdrawn from the recess. Next, when it is confirmed that the rod 22 of the wedge piece 17 is retracted from the cutout concave portion 18, the motor for driving the rotary base 1 is operated, and this operation is repeated to automatically wind up.

1 shows an embodiment of a multi-axis drive transmission device according to the present invention, which will be specifically described below with reference to the drawings.

Reference numeral 1 denotes a rotary base plate having teeth 1a engraved on its outer periphery.
Further, the central portion of the rotary base 1 has a frame 2 and a rotary shaft 4 supported by a bearing body 3 mounted on the outside of the frame 2 via a flange 3a, and the rotary shaft 4 has a key at its tip. The rotary base 1 is attached to the rotary base 1 via the rotary shaft 1 so that the rotary base 1 can rotate about the rotary shaft 4.

On the turntable 1, a plurality of winding shafts 5 are arranged at regular intervals on a radius centered on the rotating shaft 4.
5 are arranged, and the winding shafts 5, 5 ... Are borne by a bearing body 6 mounted via a seat plate 7 and a flange 6a.

A transmission member 8 having a flange 8a is attached to one end of the winding shaft 5 protruding from the bearing body 6,
Further, a disc 10 is attached to the flange 8a of the transmission member 8 via a leaf spring 9.

Further, the disk 10 has a plurality of through holes 10a.
And a bolt 11 screwed into the flange 8a is inserted into the through hole 10a.

Further, the disc 10 is made to correspond to a friction plate 13 of an electromagnetic clutch A structure mounted on a drive shaft 12 on the side of the frame 2 on the same axis as the winding shaft 5 with a slight gap. Is located.

The coil 14 side of the electromagnetic clutch A is attached to the frame 2. The drive shaft 12 is rotatably supported by the frame 2 and a bearing body 15 attached to the frame 2 via a flange, and one end of the drive shaft 12 has a gear 16 that meshes with a gear from a drive unit (not shown). Is installed.

The take-up shaft 5 is located on the rotary base 1 near the outer periphery thereof and in the vicinity of the bearing body 6 of each take-up shaft 5, on the same axis as the drive shaft 12 provided on the frame 2 side. There is provided a locking piece 19 having a cutout recess 18 for locking the wedge piece 17 to be clamped at the time.

The wedge piece 17 is guided by a guide member 20 attached to the fixed side of the frame 2, and is also attached to the tip of a rod 22 from a solenoid valve 21 similarly attached to the fixed side. The wedge piece 17 is engaged with or disengaged from the cutout recess 18 of the engaging piece 19 by the operation of the solenoid valve 21.

[0016]

As described above, according to the present invention, any one of a plurality of shafts arranged on the rotary base that rotates and moves corresponds to the drive shaft provided at one position of the frame of the path along which the rotary base moves. If this is possible, the rotary base is clamped, the clamp is checked, the electromagnetic clutch A is energized, the clutch is put in, the shaft and the drive shaft are connected, and the rotation of the drive shaft corresponds to any one of the above. When the rotation of the shaft is transmitted a certain amount, the electromagnetic clutch is released and the clamp on the rotary base is released, and when the release of the clamp is confirmed, the rotary base is moved again and repeated. It is automatic and rationalization is achieved, and further, a driving device such as a motor for each axis is unnecessary and wasteful as in the prior art, which is economically effective.
