Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conventional sheet processing machine for performing ruled lines and slot processing on a cardboard sheet.
In addition to the A type case, it is possible to change the A type processing to the flattening processing set in a short time without removing the blade and other processing holders when transporting the flat sheet for printing. It is a corrugated sheet slotter.

2. Description of the Related Art In a box making machine for corrugated cardboard sheets, which is generally called, a sheet feeding sheet hopper is sequentially fed at regular intervals, passes through a plurality of printing units, and is ruled and slotted. Has been cut

Originally, in a box making machine, one corrugated cardboard sheet is fed, printed and scored with a crease axis for one rotation of the machine, and a corrugated board sheet is attached by an upper blade attached to the upper blade axis. Is cut

The upper and lower ruled line holders, the upper and lower feed rollers, and the upper and lower cutting blade holders are used to convey the corrugated cardboard sheet during the rotation of the machine so as not to cause timing deviation.

The upper crease ring and the lower crease ring, the upper blade holder and the lower blade holder rotate together with other feed rollers during machine operation when processing the A type case, and are attached to these holders. Cut and corrugate corrugated cardboard sheets with upper and lower blades or ruled line rings. When flattening and processing with this structure, if the interval between the upper and lower blade holders is widened so that there are no holder scratches or pushing marks on the cardboard, there will be play and timing deviation when the cardboard sheet passes between the upper and lower holders. Wake up

[0006]

DISCLOSURE OF THE INVENTION In a box making machine for scoring and cutting a corrugated cardboard sheet, it is possible to prevent the occurrence of a sheet play caused by a timing deviation in the cutting unit, and to prevent each processing shaft from rotating with the machine. And the feed shaft can be synchronized rotation

Also, the rotation of the upper cutting shaft and the upper ruled line shaft is stopped. By rotating the upper and lower sheet feeding rollers, the lower notch shaft, and the lower ruled line shaft, a structure that allows the corrugated board sheet to be conveyed

The rotation of the upper cutting shaft and the upper ruled line shaft is stopped, and a part of the outer periphery of the upper blade holder and the upper ruled line ring is notched so that the corrugated cardboard sheet, which is not subjected to the cutting process such as flattening, is passed over. Allows the corrugated cardboard sheet to be conveyed by the sheet feed roller, feed shaft, etc. without the corrugated cardboard sheet touching the blade holder and upper ruled line ring.

[0009] The remaining outer peripheral portion of the upper blade holder and the outer periphery of the upper ruled line ring, other than the cutout portion, ensures that the corrugated cardboard sheet can be conveyed without causing play when the A type case is processed. To

[Means for Solving the Problems] Upper A, lower A1, crease line lower B1, feed roller upper C, lower C1, cutting shaft lower D1, feed roller upper E, E1, cutting shaft for conveying corrugated cardboard sheets Lower F1 rotation drive, on ruled line axis B, on cut axis
The rotation drive of D and F is made into the mechanism that can be driven separately.
When machining a normal type A case, all axes are tuned and synchronized, and when machining a flat case without cutting, the ruled line axis B, incision axis D,
Cut out a part of the processing holder attached to F,
The cutout is aligned with the sheet pass line, the rotation of each upper shaft is stopped, and only the feed roller shaft of the sheet and the lower part of the cut shaft are driven to convey and pass the corrugated cardboard sheet to make one rotation of the machine. The sheet with the maximum effective paper width can be cut without scratches, and the ink printed in the previous process is not contaminated.

That is, the above-mentioned object of the present invention, the flattening process of corrugated cardboard sheet and the process of the usual A type case can be easily processed in a short time, the rotation of the notch upper shaft and the ruled line upper shaft is stopped and fixed, A part of each processing holder provided on each of the shafts is provided with a notch, and the notch prevents stains on the printing when processing a corrugated cardboard sheet, and also does not cause cut scratches. Is characterized by

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is an overall view of a slotter unit for performing ruled line processing and cutting processing of a box-making machine for sheet-fed corrugated sheets. A, lower A1, ruled ring upper B, lower B1, feed roller upper C, lower roller C1, upper cutting axis D, lower cutter axis D
1, the feed roller upper E, the lower roller E1, the upper cutting axis F, the lower cutting tool axis F1, on each axis, each of the processing purpose Tsubushikoro a1 ~ a5, crease ring b1 ~ b5, feed roller c1 ~ c5 ,
Upper cut holders d1 to d5 and b1 to b5 groups are provided. This time, each holder is not shown.

In the embodiment of the present invention, the upper shaft (A), the lower shaft (A1), the ruled line lower shaft (B1), the feed roller shaft (C), the lower shaft (C).
1), undercut axis (D1), and (F1) can always be driven, and the ruled line upper axis (B) of each machining axis, upper cut axis (D), and
