BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for processing a scroll, wherein the printing (copying) or other marking process (hereinafter referred to as "printing" as a whole) and a handling device such as a folding device or a format adjusting device For example, the present invention relates to a processing method and an apparatus capable of performing an operation of forming an image on paper. The present invention relates to, but is not limited to, a treatment apparatus in which paper or other material is released from a continuous roll on a roller.

It is well known to pass a paper from a roller through a printing machine to form a series of images on the paper and then rewind, cut the sheet, or fold it into various formats. However, there is a fundamental problem in this prior art that serious limitations are placed on the efficiency of the printing press. This is a problem called "stop time". Once the printer is up and the paper starts running, printing happens very quickly. However, in a known printing press, a long time delay may occur when the paper feeding method or the printing target is changed. For example, a print job must be stopped when a different image is printed, a repetition range of the image is changed, a different color is used, or a folding format is changed. It is extremely difficult to make such a change in the configuration of a known printing press, and thus the non-operating time (stopping time) of the printing press is much longer than the idle operating time.

Another problem with the conventional apparatus is that the printing press is configured to apply to only one specific printing, and such printing press is marketed as a single item only. This actually means that if the owner of the press wants to do something more complex than what the machine can do now, the owner has to rebuild most of the work or buy a completely new machine.

Accordingly, the gist of the present invention is to overcome or at least ameliorate the above problems by constructing a scroll processing apparatus which has the advantage of being modular, capable of making various changes during operation, ie feeding, and expanding the capacity if necessary.

The scroll processing system according to the present invention is divided into three parts, the first of which is to unroll the roll from a roll or rail and feed it to another part of the apparatus, the second is to print an image on the roll, and the third is to print Part of a device for processing rolled scrolls. The present invention relates to three parts of the device.

The invention relates in particular to the relationship between the printing device and subsequent handling of the scroll. The printing industry has developed in two directions. One of them relates to the handling of continuous scrolls as described above, and the other relates to the handling of sheet materials. In general, each form has its own problems, and those skilled in the art tend to focus on their own fields. However, the problem of grounding of scrolls in the field of handling continuous scrolls can be effectively solved using techniques in the field of handling sheet materials, which have been developed to handle the products of sheet feed presses. Thus, the present invention proposes a manner in which the discharge from a roll press is cut into sheets and the sheets are fed to a grounding device.

Accordingly, the present invention includes a printing step of printing on at least one roll; Cutting the printed scroll into a plurality of separate sheets as a relationship in time with the printing; And grounding each sheet by a folder operated in dependence upon arrival of the sheets in a timely manner. At this time, the printing material is continuously moved from before printing to the start of folding of the sheet.

In addition, the present invention comprises the steps of printing on at least one roll; Forming a longitudinal ground in the printed roll; Cutting the printed scroll into a plurality of separate sheets in a timely associated relationship with the printing step; And grounding each sheet with a folder that operates in dependence of the arrival of the sheets on a timely basis but independently of the printing on the rolls.

Similarly, the present invention provides a printing apparatus for continuously printing at least one roll of printing material; Scroll conveying means for continuously conveying printed scrolls, up to cutting means for acting in a timely relation with the printing device to cut the roll into a plurality of separate sheets; And sheet conveying means for continuously conveying the sheets, up to a grounding means for operating the sheets in a time-dependent manner but operating independently of the operation printed on the at least one roll to ground the sheets. Provide a scroll processing device.

In addition, the present invention is a printing apparatus for printing at least one scroll roll; Grounding means for forming a longitudinal grounding portion in the roll; Cutting means for cutting the roll into a plurality of separate sheets; And a grounding means which is operated in a dependent relationship to the arrival of the sheet in time but operates independently of the step of printing on the at least one roll to ground the sheet.

In addition, the present invention is a printing apparatus for printing at least one scroll roll; Tear line forming means for forming a lateral cut line in the roll; Cutting means for cutting the roll into a plurality of separate sheets; And sheet folding means, which are dependent upon the arrival of the sheet in time but operate independently of the step of printing on the at least one roll to ground the sheet.

Once the scroll is cut, the cut scroll can be fed to a buckle or knife or a combined grounder, where various known grounding operations are performed on each sheet. This is very useful when handling light print media that cannot be achieved without at least working at significantly reduced speeds.

However, according to the present invention, it is easy to stiffen the printing material by first forming the grounding portion on the roll out of the roll printing press. It is also possible to provide a cutout line for the ground portion formed by the grounder.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Referring to FIG. 1, a scroll (paper in this embodiment) handling device according to the present invention comprises three parts. The first part 1 is a part which takes paper from one or more paper rolls in the form of a roll 2 and feeds it to the printing apparatus 3 and the optional drying apparatus 4. As shown in FIG. 1, the paper roll 2 is folded at 90 ° by the paper passing through an angle bar 5. After passing through the printing apparatus 3 and the drying apparatus 4, the paper roll 2 is, for convenience, bent back through 90 degrees through the angle bar 6 and passed to the cutting and folding apparatus 7. Sheets of paper that have been properly printed, cut and folded are passed through, for example, in the direction indicated by the arrow 8 to be stacked. Of course, the arrangement of the paper roll feeder (1), printing station (3), drying station (4), cutting and folding device (7) can be installed in any arrangement, the actual form is limited by space, etc. Is determined.

The present invention relates to various developments on the components of such a device as described above.

Once the paper roll is printed, the role of the present invention begins. In most cases, while paper is in roll form, the possibility of folding the paper is limited (although more than one longitudinal ground may be formed, as described below), the combination of complex grounding operations on the output of the roll press actually applies. There are few cases.

On the other hand, techniques for grounding the sheet of paper, such as gate ground, multiple longitudinal and lateral grounds, and the like, are various, two of which are shown in FIGS. 2 and 3.

2 shows a device known as a knife folding machine, in which a sheet of paper 160 passes over a pair of rollers 161 and 162 that rotate in opposite directions. In this position, the knife 163 descends with the paper sheet 160 fixed, pushing the paper sheet 160 into the nip 164, thereby providing a reliable grounding portion. The sheet of paper 160 then passes down between the rolls 161 and 162 for later use. The knife 163 is typically connected to a detector, such as a photocell, that detects whether there is a sheet of paper 160 thereunder. In this way, the folding operation of the sheet of paper may be synchronized with the arrival of the sheet of paper 160 to the folder, for example, rather than being synchronized with the initial stage of the printing operation.

3 shows a buckle fold, in which the sheet of paper 170 passes through a pair of rollers 171 and 172 that rotate back against each other, the tip of which hits the lamp 173. With the operation of the rollers 171 and 172, the sheet of paper 170 is pushed onto the lamp 173 until its tip hits the stop 174, the position of which is determined by the desired ground position. . When it hits the paper stop 174, the paper no longer rises above the lamp 173, so the operation of the rolls 171 and 172 pushes the sheet of paper 170 into the nip formed between the two rollers 172 and 175. Do it. The paper thus forms a sharp ground, which is then moved downward by the operation of the rollers 172 and 175, which in turn strikes another lamp 176 and is also moved downward to another stop 177. In this position the sheet 170 is moved by rollers 175 and 178, between which there are other nips that form another ground. It is also possible to pass the grounded paper through a perforated nip formed in the roller 179 to form a cutout in the longitudinal direction. Therefore, the apparatus shown in FIG. 3 can continuously ground in the transverse direction and perforate the sheet of paper, and can provide some of the apparatus with one or two lamps to form a certain number of transverse ground portions. . If the direction of movement of the sheet is changed between one buckle folder and the next buckle folder, both transverse and longitudinal grounds can be provided. Generally, however, the first ground is a transverse ground, otherwise additional equipment is needed. Also, the folding of a sheet is time dependent on the arrival of the sheet, but not on the timing of the print job.

In addition, it is possible to provide a grounding device that combines the knife and buckle grounding.

4 and 5, the paper roll 2 from the roll printing machine is cut into pieces by the blade device 180. As shown in FIG. 4 is a perspective view of the device, wherein the paper roll from the printing press is primarily folded by 90 ° by the bar 6 as already indicated in the description of FIG. Of course, this is not essential, and the course of the roll to the blade device 180 may be straight, as shown in dashed lines in FIG. The blade device 180 is driven by a drive shaft connected in common with the print station. In addition, a drying apparatus may be provided as described in FIG. Once the blade device 180 cuts the roll into sheets, the sheets are sent to a grounder 181, which may be configured as a buckle folder as shown in FIG. Of course, the knife folding machine shown in FIG. 2 may also be used. It should be borne in mind here, however, that the moving speed of the roll out of the printing press is faster than when handled with a known grounding device. And the flow of the sheet needs to be divided so that the lower flow follows two or more paths. In this embodiment, a divider 183 is provided such that some of the sheets are sent directly over the grounder 181 and the others are switched to another grounder 182. Another redirection occurs at devices 184 and 185. Two-path processing of such sheets of paper is already known. Therefore, a detailed description thereof will be omitted here. It is only clear that the number of grounding parts of the paper can be arbitrary depending on the purpose to be used according to the present invention.

As described above, the primary ground portion of the paper is generally a transverse ground portion. However, Figure 5 illustrates a simple method of providing a longitudinal ground portion as the primary ground portion on paper. This is especially necessary when using thin paper that is not easy to handle with the buckle folding machine described in FIG. The paper roll 2 from the printing machine and the drying device is passed through a triangular plate 190, where the paper is made triangular, as the paper descends from the roller 191 to another pair of guide rollers 192. Longitudinal grounds are formed on the paper. A neck is formed between the rollers 191 and 192. Therefore, the paper fed to the buckle folding machine 193 is once folded in the longitudinal direction, which reduces the tendency of the machine not to move in the folding machine. However, the blade or other cutter 194 must be provided before the roll enters the buckle folder 193.

As described above, the grounding portion is formed directly on the paper. However, a transverse drilling device 195 may be provided upstream of the blade or other cutter 194 to facilitate transverse grounding. Moreover, the use of a roll press makes it possible to form longitudinal cutouts (holes) to facilitate the longitudinal grounding shown in FIG. By 196. This wheel 196 can also be driven from the main drive shaft to the print station. Other longitudinal grounds can likewise be formed under continuous premises. The cutout also improves quality by allowing air to escape from the interior of the ground.
