Abstract

A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the unit(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the unit(s) (48,49) to interact successively with at least two of the cartridges (40,41,42). In this way it is possible to change printing from one cartridge (40,41,42) to another, allowing changes to be made to what is printed, without halting the movement of web (2) significantly. The present invention also proposes that the cartridges (40,41,42) may have printing cylinders (43,44,45,46) of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.

Description

Processing paper and other webs

The present invention relates to a kind of roll web processing method and system of processing, this system for example can finish by printing, duplicate or the method (hereinafter being generically and collectively referred to as " printing ") of other marking cuts after printing off generic operation such as image on the roll web (for example paper), the size of folding or adjusting size.The present invention relates to the roll web system of processing, paper and other material are from the continuous roll web on the spool (alleged roll web not only refers to common paper among the present invention, also refers to other material) in this system.

Known this system of processing is rolling by the spool paper that is printed on a series of patterns behind the printing machine on it again, being cut into or being folded into various sizes.But this system also exists very big problem, and these problems have seriously limited the efficient of machine, and one of problem is " downtime ".In case the printing machine adjustment finishes, paper moves, and printing process can carry out very soon.Yet this machine must delay for a long time when printing object or delivering method are done any change.For example; print different patterns; or the repeat length of change pattern; maybe to use different colors; or the change folded size, must stop printing this moment, because there are these problems in known this press structure; make above-mentioned these change extremely difficulty and carry out, the down time (downtime) of machine is more much longer than the effective time usually.

The structure of known printing machine also has a problem, be that printing machine is designed to special printing, machine is designed to an integral body, this just means in practice, if during machine customer wants to carry out to come more complicatedly than the operation that can carry out now on his machine operation, he must carry out big repacking or buy a cover new engine.

BP GB2122975 discloses a kind of processing method and system of processing of roll web, is included on the roll web and prints, with the mode that is printed with the certain hour relation roll web that printed is cut into plurality of sheets of paper and folding each sheet-fed.But since its folding operation fully based on be printed with timing relationship, thereby to change folding spacing and will take folding device apart be equipped with different size roller, cumbersome.

Best, after roll web or each roll web were become sheet-fed, sheet-fed should be alternated to delivered to each independent folding position, and sheet-fed is folding at this place.

The present invention also provides a kind of roll web system of processing, comprise the equipment that is used at least one volume stock roll coil paper, be used for the roll web that printed is sent to the conveyer that roll web is cut into the cutting means of many single paper continuously, the action of this conveyer be printed with regular hour relation; Device with folding sheet-fed, it is characterized in that described system also comprises the conveyer that sheet-fed is sent to continuously the device of folding sheet-fed, described folding device is provided with the action that makes described folding device and depends on that sheet-fed arrives the time of folding device, and with the irrelevant mechanism of action of printing at least one roll web.

Best, this system has the device of longitudinal folding roll web or each roll web in addition between described printing equipment and described cutting means.

Best, this system also is useful on before longitudinal folding on roll web or each roll web the vertically device of perforation.

Best, this system also was useful on before roll web is cut into sheet-fed the device of cross-perforating on roll web.

Best, between the device of above-mentioned cutting means and folding sheet-fed, also be provided with sheet-fed alternately is sent to a device in corresponding two folders of folding device.

Best, the device of described folding sheet-fed comprises a buckle-fold device.

Below by for example also with reference to the accompanying drawings, will be elaborated to embodiments of the invention, wherein

Fig. 1 is the overview diagram of the paper conversion system that the present invention relates to;

Fig. 2 and 3 shows adoptable paper folding system;

Fig. 4 shows a kind of mode of processing and the folding paper that comes out from web press;

Fig. 5 shows and can adopt the sheet processing arrangement.

At first with reference to figure 1, the total system that roll web system of processing involved in the present invention is housed comprises three parts.First briefly represents by 1, and this part comes out paper and is transported to printing element 3 and optional drying unit 4 with the form of reel paper web 2 unreel from one or more paper spools.As shown in Figure 1, reel paper web 2 passes to rod 5 by one and realizes right-angle steering, after printing element 3 and drying unit 4, for simplicity, reel paper web 2 changes 90 ° of angles again by another turner bar 6 again, delivers to one again and cuts and fold mechanism (briefly being represented by Fig. 7).Through suitable printing, cut and fold the sheet-fed of processing and send to along the direction shown in the arrow 8 and pile up.Certainly, can arrange roll web input block 1, printing element 3, drying unit 4 and cut and folding device 7 arbitrarily.But practical structures is arranged and is depended on space and other similar restrictive condition.

As mentioned above, the present invention relates to the various improvement of the parts behind the printing element of this system.

After web printing is intact, in most of the cases, becoming the folding of paper of roll web form is (though may realize that one or more are longitudinal folding, this will narrate hereinafter) that is difficult to, and the folding system of loading onto several complexity of minority in web press output place is possible.On the other hand, the technology of folding page has a variety of, and for example gate-type is folding, and multilayer is laterally folded and longitudinal folding, and Fig. 2 and 3 is depicted as wherein two kinds.

Figure 2 shows that a kind of mechanism that is known as knife folding machine, in this mechanism, paper 160 passes through on the roller 161,162 of a pair of reverse rotation.When paper 160 was fixed on this position, a cutter 163 moved downward and forces paper 160 to enter " roll gap " 164, and paper is just folded up securely.Paper 160 is made next step purposes from pulling out between the roller 161,162 downwards then, and cutter 163 is connected with a photoelectric tube usually or whether similar detector has paper 160 below the detection cutter.Like this, folding operation just arrives folder with paper and gets up synchronously, rather than synchronous with the presswork of last operation.

A kind of mechanism that is known as the buckle-fold device shown in Figure 3.In this mechanism, paper 170 passes through between the roller 171,172 of first pair of reverse rotation, and its front end is run into an inclined-plane 173.The effect of roller 171,172 is to force paper 170 along the inclined-plane 173 upwards, runs into a plate washer 174 up to its front end, and the position of baffle plate 174 is according to required folding position decision.After paper was run into baffle plate 174, it just can not continue to move upward along the inclined-plane, so the effect of roller 171,172 is to force paper 170 to go into to enter roll gap between roller 172 and another roller 175, it is folding accurately that this just makes paper produce.Then, because the effect of roller 172 and 175, it moves downward up to meeting another baffle plate 177 along another inclined-plane 176 again.In this position, paper 17C is subjected to the effect of roller 175 and 178, and another roll gap between them makes paper be folded again.Can also make paper be sewn on the vertically perforation of folding back by the perforating roller between the roller 179.Like this, it is folding and to the perforation of paper that system shown in Figure 3 just can carry out continuous transverse.Several this unit that have one or two inclined-plane are set, just can realize any amount of horizontal folding.If the direction of motion of paper changes between a buckle folding machine and another buckle folding machine, the folding change of vertical and horizontal can both realize.Yet general folding for the first time all is laterally folded, otherwise just needs optional equipment.Equally, the folding of paper 170 arrives the decision of folding machine time according to its, rather than according to the time decision of presswork.

Also can adopt the folding machine of a kind of cutter formula and fence type combination.

Referring now to Figure 4 and 5,, the roll web 2 that comes out from a web press is cut into sheet-fed by a cutter 180.Fig. 4 is the perspective view of this device, and the roll web of sending out from printing machine 2 makes it turn over 90 ° by a bar 6 earlier, and this narrated with reference to Fig. 1.Certainly, this not necessarily, the route that roll web arrives paper cutting device 180 also can be straight like that shown in the dotted line of Fig. 4.Paper cutting device 180 can also be provided with a dryer unit of narrating with reference to figure by a drive shaft that printing mechanism is public.After paper cutting device 180 was cut into page (sheet-fed) with roll web 2, just by a folding machine 181, this folding machine can be a sort of buckle folding machine shown in Figure 3, also can be knife folding machine shown in Figure 2 for they.The something that should note is, the speed that the speed of the roll web that comes out from printing machine can be handled greater than known paper folding system possibly is so the paper that stream can be brought is diverted to two or more routes.In this example, system is equipped with a current divider 183, so a part of paper is directly delivered to folding machine 181, another part then flows to another folding machine 182.184,185 places can also further change direction in the unit, and it is known that the two-way of this paper is handled, and just there is no need here to be described in a more detailed discussion.Obviously, according to the purposes of paper, can carry out the folding of any number of times.

In fact, as previously discussed, folding for the first time in the paper feed system generally all is laterally folded.Figure 5 shows that a kind of first time is with regard to longitudinal folding straightforward procedure.This is particularly important for the thin paper that the buckle folding machine of using is not too easily as shown in Figure 3 handled.Deliver to a leg-of-mutton stereotype press 190 from the roll web 2 that printing machine and (may exist) drying machine come out, therefore, a slit arranged between them when paper moves downward a pair of deflector roll 192(from a roller 191) time, paper is just by longitudinal folding.Like this, the paper that passes to a total label and be 193 buckle folding machine once by longitudinal folding mistake, therefore just mistake appears in not conference when folding.Equally, should assemble upper slitter or similar paper cutter 194 on the position before coil paper enters buckle folding machine 193.

The above all is directly paper to be folded.But, laterally foldedly carry out easily in order to make, also can load onto a horizontal perforating mechanism 195 in the front of cutter or other paper cutter 194.Also having web press to pass hole 197 by perforation wheel 196, to pass vertical hole shown in Figure 5 longitudinal folding to help.In addition, this perforation wheel 196 can be driven by the main drive shaft of print system.Similarly, other longitudinal foldingly also can carry out continuously.Because air can be discharged from the hole in folding process, so perforation also helps to improve quality on folded.
