Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carousel reel, and more particularly to a carousel reel comprising a rotatable drum and a pair of strip rewinding or winding mandrels axially attached thereto.

[0002]

2. Description of the Related Art FIG. 4 is a conceptual diagram showing a drive system of a conventional band rewinding machine using a carousel reel as an example of a conventional technique.

In FIG. 4, the rotatable drum 1 is
A pair of mandrels 2a and 2b are pivotally attached. And
First, the mandrel 2a loaded with the strip coil 3a to be unwound is rotated by the dedicated motor 4a via the pinions 5a, 6a, 7a, 8a and the ring gear 9a. Rewind the strip 3 of. During this rewinding, the other mandrel 2b is loaded with the next strip material coil 3b and made to stand by.

When the rewinding of the strip material coil 3a of the one mandrel 2a is completed, the drum 1 is moved to the motor 1
0 through a series of pinions 11 and girth gears 12, as well as ring gears 9a, 9b and pinions 8a, 8
Rotate b to rotate the positions of both mandrels 2a and 2b.

Thereafter, the other mandrel 2b is driven by the dedicated motor 4b to generate the pinions 5b, 6b, 7b.
It is rotated via b and 8b and the ring gear 9b, whereby the strip material of the strip coil 3b is rewound.

On the other hand, when winding the strip material 3, the mandrels 2a, 2b not loaded with the strip material coils 3a, 3b.
Are prepared, and the mandrel 2 is wound around the mandrels 2a and 2b by sequentially rotating these mandrels in the same manner as described above.

[0007]

By the way, in the above-mentioned conventional carousel reel described above, the motors 4a, 4a, 4b, respectively dedicated for rotating the pair of strip material rewinding or winding mandrels 2a, 2b, respectively. Because it has 4b,
Large-diameter ring gears 9a, 9b, a large number of pinions 5a-8a, 5b-8b, and a large number of bearings (not shown) associated with each motor were required. Therefore, there is a problem that the structure of the drive system for the pair of mandrels 2a and 2b is complicated, the weight is increased, and the cost is increased.

The present invention has been made to solve the above problems of the prior art, and sequentially rotates a pair of strip rewinding or winding mandrels at the strip rewinding or winding position. It is an object of the present invention to provide a carousel reel in which only one motor is required.

[0009]

In order to solve the above problems, the present invention relates to a carousel reel comprising a rotatable drum and a pair of band rewinding or winding mandrels axially attached to the carousel reel. A shaft attaching / detaching means for selectively connecting one or the other of the mandrels to a single drive shaft at a material rewinding or winding position is provided.

[0010]

According to the above means, one of the mandrels is connected to the drive shaft through the shaft attaching / detaching means and rotated at the rewinding or winding position of the strip so that the strip can be rewound or taken up. Done. When the rewinding or winding of the strip by the one mandrel is completed, the connection between the one mandrel and the drive shaft is released by the shaft attaching / detaching means. Then, the drum is rotated to position the other mandrel at the strip rewinding or winding position, and the drum is connected to the drive shaft through the shaft attaching / detaching means and rotated to rotate the strip by the other mandrel. Rewinding or winding is performed.

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 is a sectional view showing an embodiment of a carousel reel according to the present invention, FIG. 2 is a front view of the carousel reel, and FIG. 1 is a sectional view taken along the line I--I of FIG. .

1 and 2, the drum 21 of the carousel reel is supported by a plurality of rotatable rolls 22. The drum 21 includes support shafts 24a and 24b for the pair of mandrels 23a and 23b and the shaft 2
5a and 25b are pivotally attached. A girth gear 28 that meshes with a pinion 27 driven by a motor 26 for rotating the drum 21 is attached to the outer periphery of the drum 21. Further, the gear 2 is attached to both the support shafts 24a and 24b.
9a, 29b, and both shafts 25a, 25b are fitted with pinions 30a, 30b which mesh with the gears 29a, 29b. And both shafts 25a, 2
Clutches 31a and 31b are attached to the ends of 5b, respectively.

The clutch 32, which selectively engages one of the clutches 31a or the other 31b, is a drive shaft 3
3 is fitted to the shaft 3 by a spline 34 and a hydraulic cylinder 35 so as to be movable in the axial direction, and the end face thereof is fitted to the shaft 25a.
Alternatively, it is adapted to mesh with the end surface of the clutch 31a or 31b of 25b. The drive shaft 33 is the mandrel 23.
It is connected to a motor 36 for rotating a and 23b. Further, the drum 21 is provided with hydraulic cylinders 37a, 37b for expanding and contracting the mandrels 23a, 23b.

Next, the operation of this apparatus will be described. First, the mandrel 23a for winding is loaded with the strip material coil 38a, the shaft 25a is connected to the drive shaft 33 via the clutches 31a and 32, and the one mandrel 23a is rotated by the motor 36. The rewinding of the strip 38 of the strip coil 38a is started. During this rewinding, the next strip coil 38b is loaded on the other mandrel 23b by a coil car (not shown).

When the unwinding of the one mandrel 23a is completed, the clutch 32 is moved to the motor 36 side by the hydraulic cylinder 35 to disengage the clutch 31a, and the shaft 25a and the drive shaft 33 are connected. To release.

Thereafter, the drum 21 is rotated 180 ° by the motor 26, the pinion 27 and the girth gear 28,
The positions of both mandrels 23a and 23b are exchanged, and the shaft center of the other shaft 25b and the shaft center of the drive shaft 33 are made to coincide with each other.
And the other mandrel 23b is rotated by the motor 36 so that the next strip coil 38b
Begin rewinding the strip material.

When the apparatus is used as a strip material winding machine, the mandrel 23a for one winding operation is first performed.
The shaft 25a and the drive shaft 33 are connected by the clutches 31a and 32, and one mandrel 23a is rotated by the motor 36, so that the strip 38 is wound into a strip coil 38a. Then, when this winding is completed, the clutch 32 is moved to the motor 3 by the hydraulic cylinder 35.
6 side, disengage from the clutch 31a, the shaft 25
The connection between a and the drive shaft 33 is released.

After that, the drum 21 is rotated 180 ° by the motor 26 via the pinion 27 and the girth gear 28, the positions of both mandrels 23a and 23b are exchanged, and the shaft center of the other shaft 25b and the shaft of the drive shaft 33 are replaced. Match the hearts, and in this state clutch these shafts 31
b, 32, and by rotating the other mandrel 23b by the motor 36, the next strip 38
Is wound into a strip coil 38b. During this winding, the first wound coil 38a is pulled out from one mandrel 23a by a coil car (not shown).

As described above, in the present embodiment, the pair of mandrels 23a and 23b are used at the band rewinding or winding position.
Need only be connected to the motor 36 by the clutches 31a, 31b and 32, so that only one motor is required,
Further, since the drive system after the clutches 31a and 31b can be greatly simplified, the total weight can be reduced by about 30% as compared with the conventional example shown in FIG.

Next, FIG. 3 shows another embodiment of the present invention.
That is, in the embodiment shown in FIG. 1, the pair of mandrels 2
3a, 23b shafts 25a, 25b are respectively cylindrical shafts 39
In this embodiment, the drum 40 is provided with the shaft 40, and the shafts 25a and 25b are rotatably provided outside the shaft 40.
As a result, the shafts 25a and 25b are shortened, the length of the entire device is shortened, and the weight is further reduced.

It should be noted that in FIG. 3, the other components are shown in FIG.
The same parts as those shown in FIG.

[0022]

As described above, according to the present invention, in a carousel reel in which a pair of strip rewinding or winding mandrels are pivotally mounted on a rotatable drum, the strip rewinding or winding is performed. By providing the shaft attaching / detaching means for selectively connecting one or the other of the mandrels to the single drive shaft at the take-out position, the driving device for the pair of mandrels may be one set. Can be simplified and thus the weight and cost of the strip winding or rewinding machine can be significantly reduced.
