Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gathering and slitting device, particularly a gathering and slitting device suitable for continuous copying slip printing machines.

In this invention, gathering means punching out appropriate cuts, for example, several elongated U-shaped cuts, into a set of stacked sheets, and then folding the punched parts so that they pass through the set of sheets. It is binding, and slitting is the process of overlapping multiple sheets and cutting them to a predetermined width at once.

In a normal continuous copying slip printing machine, after printing, the continuous copying slips are superimposed by a collector, and unnecessary parts are cut off by a slitting device attached to the printing machine, and then the continuous copying slips are gathered or glued. I'm finishing it.

In this case, since the slitting device attached to the printing machine is a press type in which a rotating blade is applied directly onto a metal roller, there is a risk that the upper and lower slips may become uneven when cutting stacked continuous slips. This tendency increases when the cut-off area is narrow, so slitting is currently performed at a lower printing speed.

The present invention is capable of performing gathering and slitting at the same time by attaching a shared type slitting device to a gathering device, and improves printing speed by eliminating irregularities in stacked continuous copy slips caused by slitting. purpose.

That is, the present invention comprises (1) a rotating drum equipped with an upper blade for gathering and an upper blade for shear type slitting;
) The present invention relates to a gathering and slitting device having a rotating drum equipped with a lower blade for gathering and a lower blade for slitting, and a mechanism in which both drums can convey paper at a constant speed.

The device of the present invention will be explained using FIG.

FIG. 1 is a plan view of essential parts showing one embodiment of the device of the present invention.

The upper blade 1 for gathering and the upper blade 2 for slitting are fixed to rotating drums 3 and 4, respectively, and the rotating drums are connected to a rotating gear 6 via a shaft 5.

The rotating gear 6 is set to work in conjunction with a separately provided printing machine (not shown) and to transport paper at the same speed as the printing speed (paper feeding speed) of the printing machine.

The rotating drums 3 and 4 are removably attached to the shaft 5 with screws 7.

Lower blade for gathering 8 and lower blade for slitting 9
uses ring-shaped blades, and the rotating drums 10 and 11
is removably attached to.

The spacing between the lower blades is adjusted to exactly correspond to the upper blades 1 and 2 by a spacing adjustment ring 12 provided between the two drums 10.11 and the blades 8 and 9.

The rotating drums 10 and 11 are connected to a rotating gear 14 via a shaft 13.

The rotary gear 14 is interlocked with the upper blade rotary gear 6 and is set so that the upper and lower sheets of continuous copying paper are fed at the same speed.

In the present invention, a shear type slitting blade is used.

This is because there is a risk that the upper and lower sheets of paper may become uneven when cutting with a press-type blade.

It is convenient to make the lower blade for gathering and slitting into a two-stage ring for easy polishing.

The width of the groove to be formed may be about 1 mm, and the depth is preferably greater than the length of the upper gathering blade.

This improves the temporary binding effect by folding the parts punched in by gathering.

The rotating drum to which the upper and lower blades are fixed also has the function of conveying continuous copy slips.

Therefore, it is preferable that the transport speeds of both papers match the printing speed of the printing machine.

Furthermore, if there is a difference in the conveying speed of both drums, the feeding of the upper sheet and the lower sheet will be uneven, resulting in misalignment, which is undesirable.

These means for adjusting the conveyance speed may be any conventional method in printing technology.

FIG. 2 shows an example of a continuous copy slip obtained using the gathering and slitting device according to the present invention.

This slip is a continuous copy slip that is fed through the feed hole 15, temporarily stapled at the gathering section 18, and separated into single copy slips along the vertical perforation line 16 and the horizontal perforation line 17 as necessary.

Although the gathering and slitting device according to the present invention was primarily designed to be attached to a continuous copy slip printing machine, it is a device that can be widely applied to the purpose of easily and temporarily binding multiple sheets without misalignment. It is.

According to the present invention, gathering and slitting of multiple stacked sheets, particularly continuous multiple sheets, can be carried out simultaneously and effectively and quickly.
