Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a corrugating machine, in which a base paper (rolled sheet) for manufacturing a corrugated cardboard sheet is supported at an axial center and is sequentially supported according to a required amount. It is related to the mill roll stand to be supplied.

(Prior Art) FIG. 5 is an explanatory diagram of an arrangement example and operation of a conventional mill roll stand, and FIGS. 6 and 7 are schematic configuration explanatory views of a conventional mill roll stand. As shown in FIG. 6 and FIG. 7, the entire structure of the conventional mill roll stand has a structure in which the left and right frames 1a and 1b are connected by a beam 2 at the upper end to form a gate-shaped frame. The four rollers 11 provided at the lower end portions of 1a and 1b can move the rail 7 laid on the floor on the rail as a movable unit from side to side in the figure. Also, the direction perpendicular to it (front and back)
Has a structure in which it can be moved on a rail (not shown) also laid on the floor by four rollers 12 attached via an elevating device (not shown). Reference numeral 4 denotes a pair of arms that holds a rolling center 3 that holds a raw paper core tube so that the rolling center 3 can be moved up and down. The pair of arms are suspended from the beam 2 and can be moved left and right. 1b By having a structure that is laid horizontally on the upper end, the floor sandwiched by the pair of arms 4 is a free space.

Next, the setting of the base paper (rolled sheet) 8 will be briefly described with reference to FIGS. 5 to 7. The base paper 8 conveyed from the outside and placed at a predetermined position on the floor is described below. It will be set.

First, the pair of rolling centers 3 attached to the arm 4
Is lowered to the left and right, and is lowered and stopped until it coincides with the axis center of the base paper 8. Then, at the next signal, the base paper 8 is slid to the center side and held, and further raised in that state to a predetermined height to complete the mounting.

Next, the roller 11 is rotated through the driving means such as the motor 13,
It is set to carry in at a predetermined position in the production line. Fig. 5 (a)
As an example, the base paper that is mounted at the position f and transferred to the predetermined position c on the manufacturing line is sequentially supplied to the next step.

During this time, the unit of the mill roll stand moves to the rear side (left side in the figure) as indicated by c → d, and the original base paper c as a spare base paper 8 is put in a tailored state via another mill roll stand. Be transferred and wait. When the base paper moved to the d position has a predetermined remaining amount or an order change,
The base paper in the standby position c is spliced and the base paper is continuously supplied. Further, the cut old base paper at the d position is transferred to the e position outside the manufacturing line and further discharged to the outside. The same operation is repeated thereafter.

FIG. 5B shows another layout example, which illustrates a method in which the base paper is carried in at the position a and carried out at the position f. Also, move the mill roll stand unit to the rear side (c → d).
In doing so, first, the lifting device is operated to lower the roller 12 so that the roller 11 is disengaged from the rail 7,
This is performed by driving the roller 12. In the figure, f
The setting operation is the same when moving to → a.

As described above, in the conventional mill roll stand, the base paper 8 can be easily attached to the base paper supply device and transferred to the production line simply by placing the base paper 8 at a predetermined position on the floor. It is characterized by the fact that the base paper 8 can be attached and detached in the same way from the front and the rear by making it a space, which allows the layout to be set freely for the loading of new raw paper and the loading of old raw paper. There is. And the free layout can improve safety and workability in relation to the front-back process. However, the conventional mill roll stand of this method has various problems described below, such as a large installation area outside the manufacturing line as a space for attaching and detaching the base paper for functionally supplying the base paper.

(Problems to be Solved by the Invention) The conventional movable unit type mill roll stand is configured so that it can be moved back and forth and left and right on a plane via two sets of rollers provided at the lower end in directions perpendicular to each other. In addition, the structure that requires the mechanism to move the 1st set side roller up and down when changing the route (running direction) becomes very complicated, and when the base paper (rolled sheet) is attached or detached, Due to the layout of transferring to, the rail installation space (laying area) increases as the unit travels, which is a drawback.

The present invention has been proposed to solve the above conventional problems.

(Means for Solving the Problems) Therefore, according to the present invention, the left and right both-side frames are connected to each other through a beam horizontally extending at the upper end to form a gate shape, and the base paper (rolled sheet) is supported by a rolling center. In a mill roll stand in which a pair of movable arms are suspended from the horizontally-arranged beam, the platform can be moved back and forth (in a direction perpendicular to the width of the base paper) on a plane by a transporting means such as rollers. This is a means for solving the problem.

(Operation) In the mill roll stand according to the present invention, the gantry can be moved back and forth, so that the base paper can be attached to and detached from both front and rear sides of the apparatus in a free space between both arms and from the floor to the cross beam. . Therefore, the base paper (rolled sheet) carried in via the conveying means (conveyor) from the direction perpendicular to the manufacturing line is sandwiched and spliced, and after feeding, it is moved to the carry-out side conveying means (conveyor) and the remaining base paper is removed. Can be discharged. By thus combining the two sets of movable mill roll stands and the transporting means for loading and unloading the base paper, the mill roll stand for supplying the base paper need only be moved back and forth at the center of the production line.

(Embodiment) The present invention will be described below with reference to the embodiments of the drawings. FIG. 1 and FIG. 2 are schematic structural explanatory views of a mill roll stand showing an embodiment of the present invention, and FIG. 3 and FIG. 1
It is an example and an operation explanatory view. In the description of the mill roll stand showing the embodiment of the present invention, the same parts as those of the conventional one are denoted by the same reference numerals, and the main body is composed of the left and right frame 1
A and 1b are connected at the upper end via a beam 2 and are configured in a gate shape. A pair of arms 4 holding a rolling center 3 that can move up and down (elevation) are attached to the beam 2. It is possible to move to the left and right in the figure through a driving means 5 such as a conveying screw. Further, four rollers 6 are provided at the lower ends of the frames 1a and 1b so that the rails 7 laid on the floor G can be moved in the front-rear direction as an integrated unit. Further, the functions of the rolling center 3 and the arm 4 for attaching / detaching the base paper (rolled sheet) 8 are the same as those described in the section of the prior art.

Next, the arrangement and operation of the mill roll stand 10 will be described. As shown in FIGS. 3 and 4, the mill roll stand configured as described above is located on the corrugated board sheet production line and is equipped with two sets 10A and 10B.
Each of them can independently move in the sheet advancing direction (the manufacturing line direction) via the. In addition, in the direction perpendicular to the line, three base paper conveying means (for example, a belt conveyor) 9
a, 9b, 9c are laid.

Next, setting of the base paper (rolled sheet) 8 will be described. FIG. 4 shows a state in which the mill roll stand 10A side is supplying the base paper, and the other side mill roll stand 10B that has released the old base paper 8 moves to the right side of the line in an empty state (b → c).
Then, it stops on the new raw paper 8 waiting at a predetermined position for loading via the conveyor 9c, and the raw paper 8 is mounted. On the other hand, the mill roll stand 10A moves to the right side (a → b) while supplying the base paper 8. Further, when the order change or the old raw paper 8 being supplied reaches a predetermined remaining amount, the leading end of the new raw paper 8 is connected to the running old raw paper via a splicer (not shown). This allows the corrugated board sheet to be continuously manufactured.

On the other hand, the old remaining base paper 8 that has been cut after connecting the base paper is released on the conveyor 9b. And then an empty mill roll stand
10A moves to the left side (b → a) in the figure, and mounts the base paper 8 carried into a predetermined position via the conveyor 9a in the same manner as described above. The remaining base paper on the conveyor 9b is carried out to the outside during this time. Meanwhile, the mill roll stand 10B that is supplying the base paper 8
Moves to the left side (c → b) in the figure and stops on the conveyor 9b, and after splicing the base paper 8 of the mill roll stand 10A under a predetermined condition (order change or completion of base paper consumption), The base paper 8 is released and moved to the right side (b → c).

After that, the above procedure is sequentially repeated to continuously manufacture corrugated board sheets. As another application example, the mill roll stand of this type, conversely, carries in the base paper 8 from the side of the belt conveyor 9b and the old residual base paper 8 from the belt conveyors 9a and 9c on both sides.
It is also possible to carry out the sheet feeding, and the continuous base paper can be fed in the same manner as the above example.

The present invention is constructed and functions as described above. Since the mill roll stand 10 is located on the manufacturing line and the traveling direction is limited to one direction, the structure of the roller (traveling wheel) 6 is simple and the cost is low. It is expected that various effects described later such as reduction of

(Effect of the Invention) Since the present invention is configured as described in detail above,
By combining with, for example, three base paper (rolled sheet) conveying means arranged at right angles to the manufacturing line, the movable mill roll stand has a setting changing device for moving means such as rollers provided at the lower end as compared with the conventional one ( No lifting device is required, and the structure is simple. Therefore, the manufacturing cost can be reduced,
Moreover, it is possible to reduce the laying floor area on the layout of loading and unloading the base paper.
