Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a core spindle and a rider roll that are engaged so as to be movable up and down along a running rail erected between support drums of a winder, and in particular, to guide each of them. The present invention relates to a vibration isolating device for a winder that has an improved structure of a support member that supports the winder.

[Prior art] Generally, paper made from pulp is first processed as an intermediate product by rolling a large diameter winding roll (diameter 3mφ, weight 30mm).
~40ton). A paper manufacturing machine that adjusts this winding roll to a predetermined width, winding length, etc. and produces a product, as shown in FIG. It consists of a slitting device 4 for forming paper 3 to a predetermined width, and a winder 7 for winding paper 3 formed to a predetermined width around a core 5 to form a paper roll 6 having a predetermined winding length. This winder 7 is as shown in FIG.
Two support drums 8 rotate and expand the diameter while supporting the papermaking roll 6 from below, and the core 5 of the papermaking roll 6 is moved up and down along a running rail 9 erected between these support drums 8. The core spindle 17 supported from both ends and the papermaking roll 6
It consists of a rider roll 10 etc. that presses down from above. The core spindle 17 is the papermaking roll 6
It supports the core in order to prevent the core 5 from wobbling laterally as it is wound, and is designed to rise along the traveling rail 9 with the core 5 as the diameter of the papermaking roll 6 expands. It's on. Further, the rider roll 10 is used to control the winding hardness of the paper making roll 6 wound around the core 5.
It pressurizes the At the start of winding, when the paper 3 is glued to the core 5, the rider roll 10
holds down the core 5 itself from above, but as the paper 3 is wound by the rotation of the support drum 8 and the paper roll 6 expands in diameter, it rises along the running rail 9 and holds the paper roll 6 from above. It will be held down. These core spindle 17 and rider roll 1
0 and is raised and lowered by a support member 11 provided on the running rail 9 to guide and support each. These support members 11 are provided with rolling rollers 12, and are movable up and down by rotating while holding the running rail 9 from both sides.

[Problems to be solved by the invention] By the way, the conventional core spindle 17 and rider roll 10 have the following problems.

When the papermaking roll 6 is wound and expanded in diameter by the rotation of the support drum 8, the layer thickness of the paper 3 from the core 5 is not constant, and the papermaking roll 6 does not have roundness. Further, a rolling roller 12 is provided on the core spindle 17 and the support member 11 of the rider roll 10 to maintain their positional accuracy, and rotates while holding the traveling rail 9 from both sides.
This is an extremely mild friction condition of rolling friction. The reason why the rolling rollers 12 are adopted is to solve the problem that when the running rail 9 is directly held between the supporting members 11, the positional accuracy of the core spindle 17 and the rider roll 10 is not maintained due to friction caused by sliding friction. This is to eliminate the problem. In this way, the running rail 9 of the support member 11
The engagement state with the rolling roller 12 is a state of slight friction, and although the positional accuracy can be maintained due to the low friction, the core spindle 17 and the rider roll 10 are engaged with the winding of the paper making roll 6 which does not have roundness. On the other hand, it was in a state where it was easy to cause slight vibrations.
There was a problem in that the minute vibrations deteriorated the quality of the paper and caused noise.

[Purpose of the invention] The present invention was created to solve problems in the core spindle and rider roll of a winder.

The purpose is to provide a winder vibration isolator that can attenuate minute vibrations caused by the winding of paper rolls and prevent deterioration of paper quality and noise caused by the vibrations.

[Summary of the invention] In order to achieve the above object, the present invention includes a set of support drums that are provided in contact with the lower part of the paper making roll and drive the paper making roll in contact with it, and a set of support drums that are in contact with the upper part of the paper making roll. A rider roll is provided to press down the papermaking roll from above, a support member rotatably supports the rider roll and the papermaking roll, and the support member is movable up and down according to changes in the winding diameter of the papermaking roll. In the winder, the supporting member is provided with rolling rollers arranged in two stages, upper and lower, which sandwich the running rail from both sides in the radial direction of the paper making roll, and the winder is provided with rolling rollers in upper and lower stages that sandwich the running rail from both sides in the radial direction of the paper making roll, and from a direction perpendicular to the sandwiching direction of the rolling rollers. A friction member is provided that protrudes and retracts to sandwich both sides of the running rail to apply frictional resistance to the side surface of the running rail, and a friction member adjusting means is provided that adjusts the frictional resistance by adjusting the protruding and retracting movement of the friction member. It consists of

[Example] Next, an example of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 4, the core spindle 17 is engaged with a running rail 9 erected between the support drums 8 by means of a support member 11.

Further, as shown in FIG. 3, the rider roll 10 is engaged with the traveling rail 9 similarly to the core spindle 17 by two upper and lower support members 11. Its vertical movement is accomplished by rolling rollers 12 provided on these supporting members 11. For example, in the case of the supporting member 11 of the rider roll 10, rolling rollers 12 move the running rail 9 from both sides as shown in FIG. This is done by rotating while holding it. The rolling rollers 12 are provided in upper and lower stages so as to sandwich the running rail 9 from both sides of the paper making roll 6 in the radial direction. The support member 11 of this rider roll 10 has a
A friction member 13 is provided for applying frictional resistance to the running rail 9 to buffer and attenuate vibrations. This friction member 13, as shown in FIG.
It is inserted into an opening 18 opened in the support member 11 so as to be located between the rolling rollers 12, and is provided so as to be movable in and out of the support member 11 facing the traveling rail 9. That is, this friction member 13 protrudes and retracts from a direction perpendicular to the sandwiching direction of the rolling rollers 12 so as to sandwich both sides of the traveling rail 9, thereby imparting frictional resistance to the side surfaces of the traveling rail. The friction member 13 is made of a lubricating material such as an oil-less metal or a synthetic resin material. Further, this friction member 13 is connected to the running rail 9 from the support member 11.
A friction member adjusting means 14 is provided for variably adjusting the movement of the friction member 13 into and out of the vehicle to push the friction member 13 toward the traveling rail 9 side. This friction member adjusting means 14 consists of a plate spring 15 and a bolt 1.
6, and this leaf spring 15 applies a flexible frictional resistance to the traveling rail 9.
In this embodiment, a plate spring 15 is used, but a coil spring (not shown) may also be used.

It is also conceivable that the friction member 13 itself be made of a flexible material such as rubber. Note that the support member 11 of the core spindle 17 also has the same configuration as the support member 11 of the rider roll 10.

Next, the operation of the winder vibration isolator 19 constructed as described above will be described.

A friction member 13 is provided on the support member 11 of the core spindle 17 and the rider roll 10 facing the side surface of the running rail 9 so as to be movable in and out.The movement in and out of the friction member 13 is variably adjusted by the friction member adjusting means 14. By being pushed out to the traveling rail 9 side,
Frictional resistance is applied from the support member 11 to the side surface of the traveling rail 9. Since the friction member adjusting means 14 is constituted by the plate spring 15 and the like, the above-mentioned frictional resistance acts variably on the traveling rail 9 and is applied flexibly. This flexible frictional resistance suppresses the slight vibrations of the core spindle 17 and the rider roll 10 that accompany the winding of the papermaking roll, and the characteristics of the leaf spring 15 moderate and attenuate the vibrations. That is, the traveling rail 9
By pressing the friction member 13 against the side surface of the paper roll 6, the slight vibrations generated by the rotation of the paper roll 6 are converted into torsional frictional force of the friction member 13 pressed against the side surface of the traveling rail, thereby obtaining a damping effect. .
In this way, since frictional resistance is flexibly applied to the running rail 9, the core spindle 17 and the rider roll 1 are
The rise of 0 is not inhibited by frictional resistance. In addition, the core spindle 17 and the rider roll 1
The position accuracy of 0 is maintained using the conventional roller roller 1.
2.

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) By pressing a friction member against the side surface of the running rail, the slight vibrations of the core spindle and rider roll that occur as the paper roll winds are replaced by torsional frictional force between the side surface of the running rail and the friction member. It is possible to dampen the vibrations and prevent the quality of the paper from deteriorating due to the minute vibrations.

(2) As mentioned in item (1), the vibrations of the core spindle and rider roll can be damped, eliminating the noise associated with the vibrations.

(3) Since the structure is simple as described in (1), maintenance such as replacement of friction members can be easily performed.
