Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting surface marking device for marking a cutting surface for each predetermined number of flat sheets cut in a finishing operation from wide winding to flat sheets. The present invention relates to a cutting surface marking device capable of efficiently replenishing paper, preventing ink from splashing onto a paper surface, and bleeding, and improving the accuracy of each predetermined number of sheets.

[0002]

2. Description of the Related Art Conventionally, in the finishing work of a flat sheet, the operator has manually read a certain number of sheets of a flat sheet cut by using a cutter, but the number of sheets cut by a cutter rotor is used. When a flat sheet that has been detected and cut is sent by a conveyor and accumulated in a stacking device, a device called a tape marker machine is used with a certain number of signals transmitted from the cutter rotor from the rear of the flat sheet while observing the timing. Has started, and it has been changed to automation in which a tape is fed between flat sheets to divide into a fixed number of sheets.

In a conventional tape marker machine, when the timing of stacking sheets on the stacking device is shifted, a certain number of sheets are different, and the tape makes a streak on the paper surface, and the tape is torn and flattened. There is a problem such as mixing into a standard size product, and complaints such as a difference in the number of standard size products, streaking, and mixing of tapes are constantly occurring, and it has been desired to solve these problems.

In order to solve the above-mentioned problems of the tape marker machine, a cutting surface marking device has been developed as an alternative to the tape for marking the cutting surface of the plain product with ink every predetermined number of sheets.

However, in the conventional cutting surface marking device, the original fabric is rewound by rewinding it from a single or a plurality of wide windings, and is cut in the width direction by a slitter device, and then cut between the slitter device and the draw roll device. It is installed and read several times with a cutter rotor, and a marking signal consisting of a saber of the cutting surface marking device is repeatedly raised and lowered by a certain number of signals to mark the original cutting surface,
After that, the flow direction is cut by a cutter rotor, and the cut sheets are sent to a stacking device and finished as a flat sheet.

A conventional cutting surface marking device will be described with reference to FIG. FIG. 5 is an overall schematic view showing a conventional cutting surface marking device. In FIG. 5, the cutting surface marking device includes a marking member 36 attached to a vertically movable facility and an ink transfer member 37 that transfers ink to the marking member 36. A pad 38 for transferring is attached.

FIG. 5 shows a state in which the marking member 36 is positioned below the cut original 44 and ink is transferred by the pad 38 of the ink transfer member 37, and the cut portion of the original 44 is opened. Ink 46 is supplied from the upper side to the pad 38 from the ink container 45, and ink is being supplied to the pad 38.

As is apparent from FIG. 5, in the conventional cutting surface marking apparatus, ink is supplied from the upper side to the pad 38 introduced into the ink transfer member 36. There is room for improvement due to individual differences such as cutting open and replenishment directly from the top by the worker, not only a fixed amount of replenishment but excessive replenishment. Further, in the method of replenishing the pad 38 with ink from the lower side, it is not easy to replenish ink because the cutting surface marking device is installed in a narrow position between the slitter device and the draw roll device.

Further, in the conventional ink transfer member 37, 1
Put 3 putts 38, so put 3
In replacing 8, it is necessary to remove the stop rings 42 at both ends of the ink transfer member 37, pull out the outer tube 41 to replace the pad 38, and mount the pad 38 again.
This is a very difficult task because it is difficult to handle in a narrow space. Also,
Since ink is replenished over the entire pad 38, the amount of ink transferred to the marking member is large, and transfer to the original fabric (sometimes referred to as a sheet) 44 is also large.
Although it showed a dark marking state, it was not preferable because it caused sheet stains due to ink splashing and bleeding. Further, it is necessary to frequently supply ink to the pad 38.

Further, FIG. 6 shows a conventional marking member. FIG. 6 is a schematic view showing a saber which is an ink transfer member in a conventional cutting surface marking device. The saber 47 shown in FIG. 6 has a square tip using a stainless plate. When such a saber 47 is used for marking, the sheet is likely to be scratched at the rectangular tip portion, and the saber itself has a mirror-finished surface property so that the ink from the pad is evenly distributed on the saber. The ink was not transferred to the ink, and ink splashing and bleeding were likely to occur during marking. further,
With the saber 47 having a square tip, when the saber 47 is raised and lowered, the tension of the sheet is lost and the rise and fall are not smoothly performed, and an unmarked portion on the sheet is generated.
