## Abstract

A slitter-scorer apparatus comprises upper and lower slitter-scorer units which are disposed in one above the other relationship and are vertically movable respectively. The apparatus can immediately change slitting and scoring operations along the flowing direction of long and flat materials, which are fed continuously, without any reduction of the flowing speed of the materials, and the operations can be performed on the materials which flow along an approximately straight line, while the total length of the slitter-scorer apparatus is shortened to the upmost.

## Background
The present invention relates to a slitter-scorer apparatus which is adapted to slit and score long and flat materials, which are continuously fed, along the longitudinal direction or flowing direction.

As slitter-scorer apparatuses of this kind, there were apparatuses of the U.S. Pat. Nos. 3,831,502 and 3,882,765 invented by the present inventor. According to these apparatuses, an order-change for slitting or scoring operation on a material, that is, an operation for changing positions of longitudinal slitting and scoring lines on the material transversely, was instantly performed without any decrease of the delivering speed of the material.

In the apparatuses, two slitter-scorer units are disposed in one above the outer relationship. When the order-change starts, the material is instantly cut off transversely by a rotary shear. The downstream portion of the material is guided to one unit currently used and passes through the unit. The upstream portion is guided to the other unit, that is, the stand-by unit provided with slitting and scoring tools, positions of which have been changed on mounting shafts in accordance with instructions of the order-change, and passes through the unit. If the material is a corrugated board sheet, the material is damaged when it is bent at an angle of approximately 7.degree. or more. Accordingly, the material must be guided at a gentle angle from the exit of the rotary shear to the entrance of the unit and from the exit of the unit to the entrance of a following process. Thus, the total length of the slitter-scorer apparatus, that is, the distance from the exit of the rotary shear to the entrance of the following process through either the upper unit or the lower unit had to be made considerably long.

An object of the present invention is to provide a slitter-scorer apparatus of a type wherein the order-change can be performed immediately, and the long and flat materials continuously fed can be delivered to the following process, without any reduction of the running speed of the materials. The slitter-scorer apparatus is shortened in the total length as much as possible. And the materials are slitted and scored while they run along an approximately straight line from the exit of the rotary shear to the entrance of the following process through the upper or lower slitter-scorer unit.

Another object of the present invention will become apparent from the accompanying drawings and the following detailed description.

According to the objects of the present invention, the upper and lower slitter-scorer units effect an ascending or descending movement during the order-change, and guide plates which are located in face of the entrance and exit of each unit are adapted to be ascended or descended, accompanied by the units.

FIG. 17 shows another embodiment wherein the rear end 43 of the lower front guide-plate 40 and the front end 91 of the lower rear guide-plate 90 are respectively supported at the projections 732 of the unit 70. In this example, support shafts 46 and 96 which are fixed at the rear end 43 of the lower front guide-plate 40 and the front end 91 of the lower rear guide-plate 90 are rotatably supported in holes (not shown) made in the projections 732 of the unit 70.

Then, the operation of the apparatus according to the present invention will be described hereinafter. As shown in FIG. 6 to FIG. 13, operating positions 601, 701, stand-by positions 602, 702 and preparing positions 603, 703 are provided in connection with the vertical movement of the units 60 and 70. The operating position is a position where the corrugated board A is extended through the unit 60 or 70, and is slitted and scored. The preparing position is a position where positions of the slitting and scoring tools of the unit 60 or 70 are changed on the shafts. The stand-by position is a position where the unit 60 or 70, the slitting and scoring tools of which have been changed positions, stands by to be moved to the operating position. The stand-by position may coincide with the preparing position, that is, the preparing position may be included in the standby position due to spaces and devices for positioning slitting and scoring tools.

When the unit 60 is located in the operating position 601 as shown in FIG. 13, positions of the slitting and scoring tools of the unit 70 are changed in the preparing position 703. After an operation for positioning tools has been completed, the unit 70 is moved to the standby position 702 as shown in FIG. 6. At the time of the order change, the unit 70 is driven firstly by a driving machine 730 in the stand-by position 702. When the order-change starts, the rotary shear 10 operates to instantly cut off transversely the corrugated board A fed continuously. As shown in FIG. 7, the deflector 20 is pivoted and the rear end 22 is diverted from the upward position 221 to the downward position 222, thereby the upstream portion of the corrugated board, which is delivered after the corrugated board have been cut off, is moved into the lower front guide-plate 40.

At the same time, the apparatuses 65 and 75 operate to raise the operating unit 60 and the driven unit 70 respectively, thereby the unit 60 is moved from the operating position 601 to the stand-by position 602 and the unit 70 is moved from the stand-by position 702 to the operating position 701 as shown in FIG. 8. When the unit 70 is raised, the support rods 44 and 94 placed on the receiving pieces 54 are raised by the projections 732 as shown in FIG. 2. Thus, the rear end of the upper front guide-plate 30 is raised through the coupling rods 34, while the front end of the upper rear guide-plate 80 is raised through the coupling rods 84. During the vertical movement of the units, the rear end 33 of the upper front guide-plate 30 and the front end 81 of the upper rear guide-plate 80 are kept aligned respectively with the entrance of the unit 60 and the exit thereof, while the rear end 43 of the lower front guide-plate 40 and the front end 91 of the lower rear guide-plate 90 are kept aligned respectively with the entrance of the unit 70 and the exit thereof. The downstream portion of the corrugated board A cut off by the rotary shear 10 passes through the unit 60 from the upper front guide-plate 30 and proceeds from the upper rear guide-plate 80 to the entrance 101 of the following process 100. The upstream portion of the corrugated board A passes through the unit 70 from the lower front guide-plate 40 and proceeds from the lower rear guide-plate 90 to the entrance 101 of the following process 100. After the unit 60 is moved to the stand-by position 602, the unit 60 is further moved to the preparing position 603, as shown in FIG. 9, to make preparations for a following order change.

According to the operation of order-changing in a case where the preparing position is included in the stand-by position and the preparing position coincides with the stand-by position, the slitting and scoring tools of the unit 70 are positioned again in the stand-by position 702 when the unit 60 is located in the operating position 601 as shown in FIG. 6. After the slitting and scoring tools have been positioned, the unit 70 is driven by the driving machine 730. When the order-change starts, the rotary shear 10 operates to instantly cut off transversely the corrugated board A fed continuously, as shown in FIG. 7, and the upstream portion of the corrugated board A, which is delivered after the cutting operation, is moved to the lower front guide-plate 40. At the same time, the apparatuses 65 and 75 operate respectively to raise the operating unit 60 and the racing unit 70, thereby the unit 60 is moved from the operating position 601 to the stand-by position 602 and the unit 70 is moved from the stand-by position 702 to the operating position 701 as shown in FIG. 8. The downstream portion of the corrugated board A passes through the unit 60 from the upper front guide plate 30, thereby the portion is moved from the upper rear guide plate 80 to the entrance 101 of the following process 100. The upstream portion of the corrugated board A, which has been moved to the lower front guide-plate 40, passes through the unit 70 from the lower front guide-plate 40 and proceeds from the rear guide-plate 90 to the entrance 101 of the following process 100. When the unit 60 is moved to the stand-by position 602, the slitting and scoring tools are positioned again to make preparations for a following order change.
