Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a winding device used in a finishing section of a paper mill.

[Prior Art] As a winding device used in a finishing section of a paper mill, various types of winding devices have been proposed in the past, and an example thereof is shown in Japanese Patent Application Laid-Open No. 50-90857. There is. In this known example, as shown in FIG. 2, the rewinding roll (original material) is divided and sent, and the paper is wound around a rotating core 3 and the core 3 is pressed against a winding drum 1 to wind the paper. The winding roll 2 is formed by sequentially winding the tape with a certain hardness by the nip pressure between the winding drum 1.
At this time, since the winding hardness of the winding roll 2 is determined by the nip between the winding drum 1 and the winding roll 2, as the paper is wound and the winding roll 2 becomes thicker, the winding drum 1 is wound. The core 3 to keep the nip between
Is designed to be moved. This movement of the core 3 is performed by a carriage 4 supporting the core 3 via a core chuck.
In a direction away from the winding drum 1 via a power transmission mechanism of a fluid actuator such as an air cylinder (not shown) along the guide rail 6 on the upper surface of the support (station) 5 according to the winding thickness of the winding roll 2, that is, the winding This is performed by running the drum 1 in a direction orthogonal to the axis of the drum 1, and the nip is held at a fixed position in association with the thickening of the winding roll 2 and the movement of the carriage 4. Further, when the winding roll 2 has a required diameter, the fluid actuator 8 tilts the support base 5 laterally away from the winding drum 1 about the fulcrum O so that the surface of the winding roll 2 becomes a floor surface (or a lifter). 7 is grounded and the core 3 is removed from the core chuck, so that the winding roll 2 can be unloaded from the support base 5.

[Problems to be Solved by the Invention] However, in the case of the above-described conventional winding device, the height dimension of the support base 5 becomes an obstacle, and there is a limit to the diameter of the winding roll 2 that can be unloaded. That is, when the diameter of the winding roll 2 is large, when the support base 5 is tilted, the surface of the winding roll 2 directly contacts the floor surface 7 as shown by the chain double-dashed line, but when the diameter of the winding roll 2 is small. Even if the support base 5 is tilted until it comes into contact with the floor surface 7 as shown by the one-dot chain line, the surface of the winding roll 2 remains
It was difficult to unload it because there was a situation where it did not come into direct contact with. Therefore, conventionally, when a small-diameter winding roll 2 is unloaded, a means such as installing a spacer on the floor surface 7 so as to intervene between the winding roll 2 has been taken,
It is troublesome to install a spacer each time, and it is also a factor that hinders automation of the unloading work.

Therefore, the present invention is to provide a winding device capable of automatically unloading winding rolls having a wide range of diameters from a large diameter to a small diameter.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a support base tiltably on a side portion of a winding drum and allows a carriage to travel on a guide rail provided on the support base. And supporting the core on the carriage so that the carriage can move on the guide rail in the direction away from the winding drum as the diameter of the winding roll formed by winding the paper on the core increases. In the winding device described above, the carriage is suspended and supported by the guide rail, and the core is positioned below the rail surface of the guide rail.

[Operation] Since the carriage is hung from the guide rail provided on the support base so that the position of the core supported by the carriage is located below the rail surface of the guide rail, it is possible to use a winding roll of a small diameter. Even if there is, the roll surface can be easily grounded by inclining the support base. Therefore, it is possible to unload a winding roll having a small diameter without using a spacer.

[Examples] Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. As in the conventional winding device shown in FIG. 2, a fulcrum O is provided on the side of the winding drum 1.
Has a support base 5 which can be tilted about the carriage, and moves the carriage 4 along a guide rail 6 provided on the support base 5 in a direction orthogonal to the axis of the winding drum 1 via a power transmission mechanism. As the winding roll 2 formed by winding the paper around the core 3 supported by the core chuck of the carriage 4 becomes thicker, it goes away from the winding drum 1 together with the carriage 4 and winds with the winding roll 2. In a configuration in which the nip of the take-up drum 1 is always constant, the guide rail 6 is installed on one side of the support base 5, and the carriage 4 is hung on the guide rail 6 via wheels 10. The carriage 4 is movably supported and is built in the upper part of the support base 5, for example, to allow the carriage 4 to travel along the guide rail 6 by a power transmission mechanism such as an air cylinder, and the support base. The so as to tilt by a fluid cylinder 9.

When paper is wound around the core 3 supported by the core chuck of the carriage 4 to form the winding roll 2, the carriage 4 is located closest to the winding drum 1, and the winding roll 2 is thick. The carriage 4 is moved along the guide rail 6 in a direction away from the winding drum 1 by a power transmission mechanism in order to keep the nip between the winding roll 2 and the winding drum 1 constant and to obtain a constant winding hardness as the winding progresses. What is done is similar to the conventional case.

Now, when unloading the winding roll 2 from the support base 5, after moving the winding roll 2 together with the carriage 4 to the side opposite to the take-up drum of the support base 5, the tip of the support base 5 is turned downward by operating the fluid cylinder 9. Inclining so that the carriage 4 is hung on the guide rails 6 and the position of the winding roll 2 is set to a low position as described above. As shown, the surface of the winding roll 2 is brought into direct contact with the floor surface 7 without being disturbed by the support 5. Therefore, the winding roll 2 having a small diameter can be easily unloaded without using a spacer as in the conventional case. Also, when unloading a large-diameter winding roll 2, the surface of the winding roll will be located lower, so that even if the tilting angle of the support base 5 is made smaller than that of the conventional method, the surface of the floor surface 7 is reduced. Can be directly contacted with and can be easily removed.

As described above, in the winding device of the present invention, by simply inclining the support base 5, a wide range of winding rolls 2 from large roll diameter to small roll diameter can be grounded directly on the floor surface 7. Automatic unloading is possible.

It should be noted that the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist of the present invention, for example, using another tilting means instead of the fluid cylinder 9. Of course.

[Advantages of the Invention] As described above, according to the winding device of the present invention, the carriage is engaged with the guide rail in a hanging manner, and the core supported by the core chuck on the carriage is located closer than the rail surface of the guide rail. Since it is located at the bottom, even when unloading a small-diameter winding roll that could not be unloaded without installing a spacer, simply tilt the support to make the surface of the winding roll directly on the floor. Since it can be brought into contact with each other and can be easily unloaded, this has an excellent effect that the unwinding work of a wide range of winding rolls from a large diameter to a small diameter can be automatically performed.
