Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supplying a roll base paper to a mill roll stand in which the roll base paper is supported by a swing arm of the mill roll stand.

[0002]

2. Description of the Related Art Conventionally, a mill roll stand for supporting a roll-shaped corrugated cardboard (hereinafter referred to as a roll base) provided on a corrugator line is provided with a pair of swing arms swingably on a main body thereof. The roll shaft is supported between the swing arms by inserting the cylindrical shaft of the roll base paper into a support shaft protruding inside the tip of the swing arm. The roll base paper is of a variety of diameters, different paper qualities, and the like, is stocked in the storage section, transported by a carriage that reciprocates between the storage section and the lower portion between the swing arms, and attached to a mill roll stand. Then, the roll base paper conveyed to the lower portion between the swing arms by the bogie is clamped by the swing arm, and is set by swinging upward to the base paper feeding position in the corrugator.

[0003]

The trajectory of the support shaft of the swing arm is on an arc centered on the base end (rotation axis) of the swing arm, and the cylindrical shaft of the roll base paper is on the vertical line of the center of the bogie. However, in the case of extremely deviating from the arc-shaped orbit, particularly in those having a small outer diameter, the cylindrical shaft does not correspond to the supporting shaft of the swing arm, so that the worker lifts the roll base paper, and rotates the supporting shaft of the swing arm. The roll base paper has a large diameter even if it has a small diameter, and is formed in a cylindrical shape that is difficult to lift, making it extremely labor-intensive for workers and improving the efficiency of the work. I couldn't do it.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a roll base paper support at a lower position between the swing arms of a mill roll stand at a stop position of the roll base paper transport carriage. If the cylindrical shaft of the roll base paper is not positioned on the trajectory of the support shaft of the swing arm of the mill roll stand, the support can be moved up and down from both left and right sides of the bogie to swing the cylindrical shaft of the roll base paper. Corresponding to the support shaft of the arm, the roll base paper can be easily attached regardless of its outer diameter.

Next, a modification of the main bodies 12, 12a will be described. As shown in FIG. 6A, the roll base paper W is placed on the carts 5 and 5a.
In the above case, when one of the spindles 3 and 3a is
When the spindles 3, 3a ... extend to the cylindrical axis H of the roll base paper W,
One of the support shafts 3, 3a,... Is inserted into one end of the cylindrical shaft H on the one side, and the roll base paper W is pressed against the other. .., Which support the roll base paper W, slide to the other side of the spindles 3, 3a, and as shown in FIG.
The other end of the cylindrical shaft H is inserted into the other of the support shafts 3, 3a,.
As described above, when the roll base paper W sandwiched between the swing arms 2, 2a...
are returned to the home position by the leaf spring 28.

[0017]

In short, the present invention provides a support for the roll base paper W at the stop position Y of the roll base paper transport carriages 5, 5a below the swing arms 2, 2a... Of the mill roll stand 1.
Are provided so as to be able to protrude and retract from the left and right sides of the stop surface GL1 of the carriages 5, 5a, so that the roll base paper W on the carriages 5, 5a is provided.
If the cylindrical shaft H of the roll base paper W does not correspond to the mounting position X of the support shafts 3, 3a,...
Can be lifted to a position corresponding to the support shafts 3, 3a,..., And the support shafts 3, 3a. Therefore, the burden on the worker can be remarkably reduced, and the working efficiency can be improved. Also, the supports 22, 22a ...
Is buried under the stop surface GL1 while the carriages 5 and 5a are running, so that the roll base paper W on the carriages 5 and 5a is provided. It does not interfere with driving and does not interfere with driving.

The support members 22, 22a are formed of rollers which are long in the axial direction of the roll paper W, and the rollers 22, 22a.
Are provided in the length direction thereof, so that the roll base paper W
Rollers 22, 22a…
Even if the roll base paper W is supported in an unstable state where the axis of the roll base paper W intersects with the axis of a ..., both the rollers 22, 22a ... and the roll base paper W are cylindrical, and the rollers 22, 22a ... are rotatable. The roll paper W, which is supported in an unstable state, rotates in an arbitrary direction while ascending, and the rollers 22, 22a circumscribing this rotate in reverse, so that the roller 2
2, 22a ... can be stably supported between the cylindrical shaft H and the support shaft 3, 3.
.. are arranged on the same axis, and the support shafts 3, 3a.

Also, since the supports 22, 22a are slidably provided in the longitudinal direction thereof, even if the roll base paper W is shifted in the longitudinal direction on the carts 5, 5a, the support members 22, 22a are not slid. The roll base paper W is moved to a position where the swing arms 2, 2a... Can be clamped by the extension of the support shafts 3, 3a on the near side, so that the worker corresponds to the center between the swing arms 2, 2a. Thus, the burden of adjusting the position of the roll base paper W on the carts 5 and 5a can be eliminated, and the working efficiency can be further improved. Also, the means 28 for returning the supports 22, 22a... To their home positions is provided, so that when the roll base paper W moves from the supports 22, 22a.
The practical effect is extremely large, such as no need for troublesome positioning adjustment of a.
