Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a web roll alignment and storage device, and more particularly to a web roll alignment and storage device for supplying web rolls to a web roll unwinding device.

A web roll as used herein refers to paper,
A thin strip of plastic film, cloth, metal, etc. (hereinafter referred to as a web) is wound into a coil around a core.

Conventionally, a web roll alignment storage device for supplying a web to a web roll unwinding device has been proposed. For example, a web roll alignment storage device has been proposed in which a single support shaft holds the winding cores of a plurality of web rolls to support the web rolls, and a web roll alignment storage device in which a plurality of support shafts supporting the web rolls are provided in parallel. has been done. However, since the former has a single support shaft, the number of web rolls stored is small and the efficiency of web roll supply work is poor, while the latter allows for an increase in the number of web rolls stored, but the support shafts are installed in parallel, so installation is difficult. There is a problem that the space becomes large.

In order to solve this problem, a turret-type web roll storage device has been proposed in which multiple support shafts are arranged around a rotating shaft. The following problems occur because the motor rotates inside the machine. In other words, it cannot be installed in places with height restrictions because there is a risk of the support shaft touching above, and the support shaft rotates in a vertical plane when positioning it to the supply station that transfers the web roll. There is a possibility that the support shaft cannot be accurately stopped at the supply station due to the influence of the shaft and web roll's own weight.

The present invention has been made in view of the above circumstances, and an object of the present invention is to propose a web roll alignment and storage device that can be installed even in places with height restrictions and that allows accurate positioning of support shafts.

The present invention comprises: a rotating shaft vertically erected; a plurality of support shafts provided horizontally outward from the rotating shaft at predetermined intervals to hold the winding core of the web roll and support the plurality of web rolls in alignment; It is characterized by comprising a number of clamp mechanisms that are provided in a number corresponding to the number of web rolls on the support shaft and clamp the leading ends of the web rolls.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the web roll alignment and storage apparatus according to the present invention will be described in detail below with reference to the accompanying drawings.

Figure 1 is a plan view of this embodiment, Figure 2 is a front view,
FIG. 3 is a side view. In the figure, a base 10 has a post 12 erected upward as a rotating shaft, and this post 12 is intermittently rotated by a motor (not shown) within the base 10. Approximately triangular support plates 14, 14 are provided at the top of the post 10, and mounting plates are provided on three sides of the support plates 14, 14. Three support shafts 18, 18, 18 are provided on each mounting plate 16 to project horizontally. This 3
The book support shafts 18, 18, 18 correspond to three attachment holes 24, 24, 24 formed in the core 22 of the web roll 20 shown in FIG. That is, the web roll 20 has the mounting holes 24, 2 of the winding core 22.
Support shafts 18, 18, 18 are inserted into 4, 24,
It is supported by a support shaft 18 . Further, a center hole 25 is formed in the winding core 22, and a rewinding shaft, which will be described later, is fitted into this center hole 25.

Furthermore, the post 10 is provided with a web set shaft 26 below the mounting plate 14, and a clamp mechanism 28 further below. Clamp mechanism 28
are provided corresponding to the number of web rolls 20, and hold the leading end of the web.

The operation of the embodiment according to the present invention constructed as described above is as follows. As shown in FIG. 4, a web roll alignment storage device 30 in which web rolls are attached to a support shaft 18 is arranged to correspond to a web roll unwinding device 32. The rewinding shaft 34 of the rewinding device 32 is moved in the left-right direction in FIG. 4 by a cylinder 36. Rewind shaft 3
4 moves to the left in FIG. 4, fits into the center hole 25 of the winding core 24 of the web roll 20 to hold the web roll 20, and in this state moves to the right to support the web roll 20. Remove it from the shaft 18. At the same time, the leading end of the web is separated from the clamp mechanism 28, and the leading end of the web is fed and rewound by a device (not shown). The unwinding shaft 34 repeats the above operation to unwind the web roll 20 from the support shaft 18.
Remove them one by one. Web roll 20 of support shaft 18
When the web roll 20 is empty, the post 12 rotates 1/3, and the support shaft 18 supporting the web roll 20 moves to the unwinding device 3.
2, and the above operation is repeated again. Such a rotation stopping operation is performed, for example, by decelerating the rotation of the drive motor using a gear, transmitting the rotation to the post 12, rotating a predetermined angle, and then positioning the index cam using a wedge.

In the above embodiment, the support shaft 18 that supports the web roll 20 is rotated in a horizontal plane by the post 12, so that the web rolls according to this embodiment can be stored in alignment even in places with height restrictions. The device can be installed. In addition, support shaft 1
8 rotates in a horizontal plane and does not rotate in a vertical plane like the conventional alignment and storage device, so it is not affected by its own weight much when stopped, so it can be accurately positioned at the position to supply the web roll to the unwinding device. Can be done.

In the above embodiment, the support shaft 18 of the web roll 20
are provided in three directions, but may be provided in four or more directions.

As explained above, according to the alignment storage device according to the present invention, since the support shaft of the web roll rotates in a horizontal plane, it can be installed even in a place with height restrictions.
In addition, since it is less affected by its own weight, it can be accurately stopped at a predetermined stopping position.
