[Detailed description of the invention] [Field of industrial application] The present invention relates to a rider roll device for adjusting the winding hardness in a winding machine that winds up a strip-shaped object such as a paper web, and in particular relates to a rider roll device for adjusting the winding hardness. It also has functions.

[Prior Art] For example, at the final stage of the papermaking process, a paper web that has been given a glossy finish using a supercalender is cut to a desired width using a slitter, and then wound using a winder.

There are various types of winding machines, such as a two-shaft winding type with two winding drums and a single-shaft winding type with one winding drum.

In recent years, the diameter of take-up rolls has tended to become larger, and the requirements for the initial winding hardness of the core have become even harder. Therefore, the core and take-up roll are pressed down with the required pressure by a rider roll device that idles and supports the pressure roll.

Conventionally, the cores were loaded manually, or as shown in FIG. 3, the cores were loaded from a core introducing device b installed below the winding drum a, and the cores c were placed at the tip of the piston rod e of the air cylinder d. holder f

[Problems to be solved by the invention] Therefore, various devices such as a rider roll device and a core supply device are arranged around the winding machine.
The structure and operation have become very complex.

[Means for Solving the Problems] The present invention was made for the purpose of solving the above-mentioned conventional problems and simplifying the device by integrating the core supply and the rider roll device.
A core supply device is disposed above the winding drum, and a rider roll support is disposed on the side of the winding drum, and the rider roll support is perpendicular to the axis of the winding drum during winding. A rider roll is mounted so as to be horizontally movable in the direction in which the rider roll moves, and a core holding arm is rotatably mounted on both ends of the axis of the rider roll, and the core holding arm of the core feeding device is placed at least upwardly during core feeding. It is characterized in that the rider roll support body is supported so as to be movable up and down so as to be movable between the position and the core passing position on the side of the winding drum.

[Operation] The core held by the core holding arm is fixed by the chuck support, the core holding arm is released backward, and the core is pressed against the winding drum with the required pressure by the pressure roll, thereby starting winding. can do.

As the winding diameter increases, the pressure roll is moved backward and the rider roll support is raised to maintain the desired nip pressure.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

Figures 1 and 2 are an embodiment of the present invention,
Two support shafts 2 and 3 are arranged on both sides of the winding drum 1 connected to the rotational drive device, each having the same length as the winding drum 1 and parallel to the winding drum 1, and each supporting shaft 2 .
The piston rods 9 are connected to each other through brackets 10 at their tops, and the protrusion of each piston rod 9 connects the support shafts 2 and 3 through each side plate 4.
It is designed so that it can be raised and lowered.

A plurality of sets of rider rolls 11 and core holding arms 12 are disposed on each of the support shafts 2 and 3 so as to be staggered on the left and right sides with their phases shifted.

That is, a pair of brackets 13,
13 is movably or fixedly attached to each bracket 13 with each support shaft 2 passing through it, and guide grooves 14, 14 are recessed in the lower part of the inner surface of each bracket 13, 13, respectively. A slide plate 15 is fitted and supported in each guide groove 14, 14,
A pressure roll 16 is idle supported on the lower surface of the slide plate 15 by brackets 17 so that the pressure roll 16 is parallel to the winding drum 1. a core holding arm 12 having a curved core holding concave seat 19 on the shaft 18 of the pressure roll 16 projecting outward from the brackets 17, 17;
12 are rotatably mounted with the same phase on both sides, a horizontal plate 21 is fixed between each core holding arm 12, 12 so as not to interfere with the pressure roll 16, and a horizontal plate 21 is fixed in the longitudinal direction of the horizontal plate 21. The anti-winding drum 1 of the slide plate 15 is mounted on a bracket 22 provided at the center.
The piston rod 26 of the air cylinder 25, which is pivotally attached to the side by the bracket 23 and pin 24, is attached to the pin 27.
It is connected.

An air cylinder 29 is pivoted by a pin 30 to a horizontal member 28 fixed to the winding drum 1 side between the brackets 13, 13, and the tip of the piston rod 31 of the air cylinder 29 is attached to the slide plate 15 by the bracket 32 and pin 33. They are connected by

Furthermore, a core supply device 34 is provided above the winding drum 1.
are arranged in the axial direction of the winding drum 1, a core guide 35 and a rotation stopper 36 are attached to both sides of the core supply device 34, and the core 37 in the core supply device 34 is attached to the core holding arms 12 on both sides. It is arranged so that it can be distributed and supplied to.

With the above structure, when loading the core 37, the piston rod 9 of the air cylinder 8 is projected, and the support shafts 2, 3, rider roll 11, and core holding arm 12 are pulled up together through the side plate 4, and the core 37 is loaded. Connect the core holding arm 12 to the air cylinder 2
5 to the core receiving position A, and the tip of the I-core holding arm 12 is made approximately at the same height as the core guide 35.

When the core 37 is introduced into the core supply device 34 and the rotation stopper 36 on the core supply side is rotated and opened, the core 3
7 roll on the core guide 35 on both sides, and are received by the concave seats 19 of each of the core holding arms 12.

When the piston rod 9 of the air cylinder 8 is pulled in in this state, the core holding arm 12 etc. are lowered together through the side plate 4, and the height of the center of the held core 37 and the height of the center of the winding drum 1 match. It is stopped at the core transfer position B.

Here, if the stroke of the air cylinder 8 is set so that the stroke end position coincides with the core receiving position A and the core passing position B, the operability will be improved.

The core 37 at the core transfer position B is supported at both ends by chuck supports running on support frames (not shown) on both sides of the winding drum 1, and the core 37 is pressed against the winding drum 1 by the chuck supports. The core holding arm 12 is an air cylinder 25
The piston rod 26 of the piston rod 26 is retracted.

Furthermore, when the piston rod 31 of the air cylinder 29 fixed between the brackets 13, 13 is pulled in, the slide plate 15, which is connected to the piston rod 31 via the bracket 32 and the pin 33, slides within the guide grooves 14, 14. The slide plate 15
A pressure roll 16 supported by a bracket 17 on the lower surface of the core 37 backs up the core 37 from the side.
The desired nip pressure is applied.

In this way, winding is started, and as the winding diameter increases, the piston rod 3 of the air cylinder 29
1 to protrude so as to maintain a predetermined nip pressure,
The pressure roll 16 is moved back together with the slide plate 15. When the winding diameter further increases, the piston rod 9 of the air cylinder 8 is projected to raise the rider roll 11.

It should be noted that the rider roll device of the winder of the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

[Effects of the invention] As described above, according to the rider roll device of the winding machine of the present invention, the pressure roll is disposed so as to be movable in the vertical and horizontal directions, and the core holding arm is also provided. , loading of the core and application of nip pressure can be performed simultaneously, and various excellent effects can be achieved, such as being able to significantly simplify the equipment and structure around the winding machine compared to the conventional method.
