Abstract

PURPOSE:To enable a web roll to be arranged and stored accurately even in a place where a support shaft can be located and the height is limited, by projecting horizontally a shaft for supporting a web roll from a rotary shaft erected vertically while additionally providing a clamp mechanism for clamping an end of web roll. CONSTITUTION:A post 12 as a rotary shaft is erected from a base 10, and provided on the upper portion with a mounting plate 16 through a support plate 14. A plurality of support shaft 18 are provided projectingly on the mounting plate 16 and inserted into a plurality of mounting holes formed in a winding core of a web roll 20. The post 12 is provided on the lower portion with a web set shaft 26 and a clamp mechanism 28 by which an end of the web is clamped. An arraging and storing apparatus 30 thus formed is opposed to an unwinding device 32. The web roll is supported by inserting an unwinding shaft 34 into the center hole of the winding core and withdrawn from the support shaft 18 which can be installed even where the height is limited since it rotates in the horizontal plane.

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.

The web roll used in this specification refers to a thin strip material (hereinafter referred to as a web) made of paper, plastic film, cloth, metal, etc., wound into a coil around a core.

BACKGROUND OF THE INVENTION In the past, web roll alignment and storage devices have been proposed for supplying webs to web roll unwinding devices. 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 the web roll supply operation is poor, while the latter increases 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 at the supply station where the web roll is delivered. There is a possibility that the support shaft cannot be accurately stopped at the supply station due to the influence of the weight of the shaft and the web roll.

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 locations with height restrictions and that allows accurate positioning of support shafts.

The present invention includes a rotating shaft that stands upright in the vertical direction, and a plurality of support shafts that are provided horizontally outward from the rotating shaft at predetermined intervals to hold the winding core of the web roll and support a number of web rolls in alignment. and 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.

FIG. 1 is a plan view of this embodiment, FIG. 2 is a front view, and FIG. 3 is a side view. In the figure, a post 12 as a rotating shaft is installed upward on the base lo, and this post 12 is attached to the base lo.
It is intermittently rotated by a motor (not shown) in 0. A substantially triangular support plate 14.14 is provided at the top of the post 10, and mounting plates 16 are provided on three sides of this support plate 14.14. Each mounting plate 16 has three support shafts 18, 18, 18 projecting in the horizontal direction. These three support shafts 18.18.18 are attached to three mounting holes 24.24 formed in the core 22 of the web roll 20 shown in FIG.
．． It corresponds to 24. That is.

, the web roll 20 has mounting holes 24, 24 of its winding core 22.
．． The support shaft 18.18.18 is inserted into 24, and the support shaft 1
Supported by 8. Further, a center hole 25 is formed in the winding core 22, and a rewinding shaft described later is fitted into this center hole 25. Furthermore, a web set shaft 26 is provided below the mounting plate 14 on the post IO, and further, A clamp mechanism 28 is located below it.
will be provided. Clamp mechanisms 28 are provided corresponding to the number of web rolls 20, and clamp the leading ends 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 face a web roll unwinding device 32. The rewinding shaft 34 of the rewinding device 32 is connected to the cylinder 3
6 in the left and right directions in FIG. The unwinding shaft 34 moves to the left in FIG.
0, and in this state move to the right to remove the web roll 20 from the support shaft 18. At the same time, the web leading edge is separated from the clamp mechanism 28, and the web leading edge is fed and rewound by a device (not shown). Rewind shaft 3
Step 4 repeats the above operation to remove the web rolls 20 one by one from the support shaft 18. When the web roll 20 on the support shaft 18 becomes empty, the post 12 rotates 1/3, the support shaft 18 supporting the web roll 20 comes to a position facing the rewinding device 32, 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 it by 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 2o is rotated in a horizontal plane by the bosses 2, so that the web roll alignment and storage device according to this embodiment can be used even in places with height restrictions. can be installed. In addition, since the support shaft 18 rotates in a horizontal plane and does not rotate in a vertical plane as in conventional alignment and storage devices, it is less affected by its own weight when stopped, so it can be accurately positioned to feed the web roll to the unwinding device. can be positioned.

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

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