Abstract

PURPOSE:To simplify a process loading the base paper having a different winding diameter by constituting arm fitting rails fitted with a pair of support arms horizontally movably respectively so that they can be horizontally moved up and down along individual stanchion bodies. CONSTITUTION:A pair of support arms 2, 2' are horizontally removably fitted respectively to arm fitting rails 6 horizontally suspended across two stanchion bodies 5, 5. The axis tube A' of the base paper A can be pinched from both sides as shown by two-dot chain lines in the lower part of the figure, or its pinch can be released as shown by solid lines. When the base paper is to be loaded, support sections 10, 10 of the support arms 2, 2' are pinched in coincidence with the position of the axis tube A'. When the base paper having a different winding diameter is to be loaded, the stop position of the support arms 2, 2' lifted or lowered on a vertical motion locus only needs to be different, and the base paper loading process is simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a mill roll stand that constitutes a part of a corrugating machine for producing corrugated cardboard and is used to load corrugated cardboard rolls.

<Prior art> A fine tube of corrugated cardboard is held in both directions,
A conventionally known mill roll stand in which a pair of support arms capable of rotatably supporting the base paper are so-called swing-type arms that simply draw a motion trajectory like the C-0 curve in FIG. 1. In the JM paper loading process, if the rolled diameters of the base paper are different, for example, as in the base papers A and B in Fig. 1, each narrow tube A', B' of the loaded base paper is moved by the C-D movement of the support arm. There was the difficulty of having to adjust to points E and F, which were shifted both vertically and horizontally on the trajectory.

In particular, each time the roll diameter of the loaded base paper differs, the horizontal position of the base paper, in other words, the position of the base paper supply track shown by the track truck 17 in FIG. 1, must be aligned with the movement trajectory of the swing arm. This has the disadvantage that the operation becomes complicated and loading operation becomes difficult.

<Objective of the Invention> The present invention was developed in view of the above-mentioned circumstances, and its purpose is to maintain the position of the base paper supply trajectory in the base paper loading process, even when the roll diameters of the loaded base papers are different. It is an object of the present invention to provide a mill roll stand in which there is no need to align the base paper with the support part of the support arm, in other words, the position of the feed trajectory of the base paper is always kept constant.

<Configuration of the Invention> In order to achieve the above object, the mill roll stand of the present invention has the following configuration.

That is, a pair of support arms that can sandwich the core tube of the winding base paper from both sides and support the base paper in a rotatable manner,
The arm mounting rails are respectively attached to arm mounting rails installed between the pillar bodies so as to be movable in the lateral direction, and the arm mounting rails are configured to be vertically movable along the respective pillar bodies.

<Example> Hereinafter, the present invention will be explained based on illustrated embodiments.

In the figure, reference numeral 1 indicates a so-called two-axis mill roll stand employed in the present invention, and the right side of FIG. 1 shows the loading process of base paper, and the left side shows the state in use. Since the configurations of both are the same, the description of the configuration of one will be used to explain both.

In FIG. 2, reference numerals 2.2' denote a pair of support arms, and the bases 3 of the support arms 2, 2' are connected to two support columns 5, 5 vertically erected on the base 4. They are respectively attached to arm attachment rails 6 horizontally installed between them so as to be movable laterally. The support arm sliding drive mechanism for laterally moving the support arms 2, 2' along the arm mounting rail 6 includes a support arm drive motor 7 fixed to the arm mounting rail 6, and a rotating shaft of the motor 7. It consists of a long sliding screw 8 connected to the long sliding screw 8, and a sliding nut 9 that is screwed into the long sliding screw 8 and fixed to the support arm 2, and is slidable by forward and reverse rotation of the long screw 8. Via the nut 9, the support arm 2 is laterally reciprocated along the arm mounting rail 6. Such support arms 2, 2'
, i.e., by moving the base paper A forward and backward with respect to the narrow tube A'.

The support arm 2゜2' indicated by the two-dot chain line in the lower part of Fig. 2 can hold the central tube A' of the base paper A from both sides, or the support arm 2゜2' indicated by the solid line in Fig. The structure is such that the clamping can be released. It goes without saying that the lateral movement of the support arms 2, 2' is controlled by a limit switch (not shown) or the like.

Further, at the tips of the support arms 2, 2', there is a roll sheet A.
A substantially conical support portion 10 is provided which can sandwich the narrow tube A' from both sides thereof and support the base paper A in a rotatable manner. Furthermore.

A brake device 11 for adjusting the rotational drive of the support section 10 is provided at the tip of the support arms 2, 2'.

Note that the tension of the supported base paper A is adjusted by the action of this brake device 11.

The arm mounting rail 6 is constructed between the respective support bodies 5, 5 so as to be vertically movable along the respective support bodies 5.5. This arm mounting rail 6 is attached to the support body 5.
, 5, the rail elevating drive mechanism includes an elevating drive motor 12 disposed within the base 4 and an elevating drive mechanism installed within the support columns 5, 5, as shown by broken lines. A long lifting screw 13 that is rotated forward and backward by the forward and reverse rotational force of the drive motor 12 via a transmission mechanism such as a spromut, a chain, or a worm gear, and is screwed onto the long lifting screw 13 and formed on the support body. The vertically extending hole 14 is fixed to the arm support rail 6 through a lifting nut 15. 16 is a metal for lifting and lowering. Therefore, when the elevating long screw 13 is rotated forward and backward by the elevating drive motor 12, the elevating nut 15 is moved up and down at a constant rate in the axial direction of the elevating long screw 13, and accordingly, the elevating nut 15 is attached to the elevating nut 15. The arm support rail 6 which has been moved up and down is also moved up and down along the support column 5.5.

Incidentally, a light sensor (not shown) provided at the tip of each support arm 2, 2' detects the position of the axial center tube A' of the base paper A; when the support parts 10 of the support arms moving up and down are brought together, The lift drive mechanism is configured to be stopped and controlled.

Next, according to the embodiment shown on the right side of FIG. 1 and FIG.
The filling process of the winding source paper will be explained.

First, the supply trajectory position of the base paper A, that is, the axial center tube position A'' of the supplied base paper A is determined on the vertical movement trajectory X-Y drawn when the support parts 10 of the support arms 2 and 2' are moved up and down. In Fig. 1, the center position of the track carriage 17 for placing the base paper running on the supply track is set as the supply track position.Now, along the base paper supply track from the direction of the arrow in Fig. 2. The supplied base paper A rises from the lowered position shown by the solid line to the raised position shown by the two-dot chain line in the upper row, passes under the fixed support arms 2 and 2', and moves as shown in FIG. The support arms 2, 2' are placed in a predetermined advanced position.
is lowered along the vertical motion trajectory X-Y to the position shown by the lower two-dot chain line, and
0 is aligned with the center tube A' position of the base paper A, and at this position, each support arm 2, 2' is advanced toward the center along the arm mounting rail 6 to sandwich the base paper in a supported state. The base paper held between the support arms in this manner is used in the use position on the left side of FIG.

Also, when loading base paper B with different roll diameters,
It is similar to the above-mentioned base paper A, except that the stopping position of the support arm 2.degree. 2', which is moved up and down on the vertical motion track gx-y, is different.

The roll diameters of the base paper loaded in this way are base paper A and base paper B.
The support arm 2, which is simply moved up and down, even if it is different as in
The only difference is the stop position of 2', and the position of the base paper supply track is constant.

<Effects of the Invention> Therefore, when mounted on the mill roll stand of the present invention, the arm mounting rails each having a pair of support arms movably attached thereto can be vertically moved up and down along each support. This is a feature of the invention, and even when loading base paper with different winding diameters, the position of the supply trajectory of the base paper can be adjusted by simply moving the support part of the support arm up and down to match the axial center tube of the base paper. Since there is no need to change it according to the shaft core tube, it has the effect of simplifying the process of loading base paper with different diameters per roll.
