Abstract

Gather-stitcher machine for joining and stapling a plurality of stacks of sheets of a magazine, and method for producing a thumb-tab index on magazines to be stapled by means of the gather-stitcher machine. In order to make it possible for a thumb-tab index to be machine-produced on the magazine which has been assembled together by the gather-stitcher machine, the machine is equipped with at least edge punching device arranged to the rear of a feeder guide mechanism in the transport mechanism's direction of travel, which device only produces punched-out portions in said stack of sheets in the long edges therein once the latter has been deposited.

Description

The invention relates to a saddle stitching machine for assembly and binding or stapling several stacks of sheets of a printing or Paper mill, in particular a magazine, with a transport device and with feeder facilities to launch the Sheet stack on the transport device. The invention is further to a method of making a service register to be bound or stapled by means of a saddle stitcher Printing or paper works directed, especially for manufacturing a markup of journals.

EP-A-761472 discloses a saddle stitching machine according to the preamble of claim 1.

It is known to print works such as pocket calendars, Encyclopedias, address directories or the like. with a markup to be provided, which is usually on the open long side of the bound Printing unit is arranged and that a fast, page-accurate Open the calendar, lexicon or the like. allows. For this purpose, the user of the printing unit can put a finger in one Place the punched register on the long edge of the individual pages, then when opening the printing unit all behind the Finger lying sides are held back by this while the rest of the leaves with the punch on the finger can scroll past. An alphabetically arranged lexicon or address directory can easily be found on every first page open each letter; Leave calendar quickly find the correct one after days of the week or months Scroll up the digit.

The production of such service registers is special for stapled printing or paper works so far only under great effort and a high level of human resources possible because the Die-cuts in the individual, assembled by a saddle stitching machine and stapled sheets are not produced can, before this on the transport device of the saddle stitcher be filed. The reason for this is that the individual sheet stacks, usually between four and contain one hundred pages of the later printing unit, but also can consist of a single folding object, by investor institutions can be opened parallel to their middle fold must, so that they reliably on the collection chain or the leading sword can be placed on the transport device. To do this, however, it is necessary that the sheet stack over the entire length of their longitudinal edges by grippers of the feeder devices can be recorded what has already been punched Die cuts cannot be guaranteed.

Works of paper or printing on their backing Printing fold can be held together by means of staples So far not mechanically with punched-outs for a surcharge register be provided, but the finished stapled Printing units must be opened at the correct location by hand and be applied to a punching device, with which the Die cuts can be made. More than a hundred copies one only to be provided with a weekly register An experienced worker can also use this type of printing hardly manufacture.

The previously described, previously customary method of manufacturing a Surcharge register for stapled paper or printing units the consequence that these are disproportionately expensive to manufacture are and are only produced in short runs. printing units with high circulation and comparatively low sales price such as in particular program magazines or the like. have so far not economically provided with a surcharge register be that on the open long side of the stapled magazine or the like. on top of each other in a relatively narrow area has punched holes arranged to open to enable the magazine on the desired weekday. In order to do so even in large quantities and very much printing units to be produced quickly at a low price It has been proposed to allow quick serve Width of the pages for the individual days of the week of a television program to change from day to day and the different widths Staple pages in front of each other so that the first in the program day of the week considered the lowest and the last day has the largest page width. With such an arrangement but especially with a large number of individual registers, for example with a program magazine for one Period of fourteen days, a lot of space on the sides of the given away the first few days of the registry.

The object of the invention is to provide a saddle stitching machine which is an automatic production of a service register on paper or printing units to be bound by stapling, in particular allowed on magazines. Furthermore, with the invention a method for automatically creating a markup register to be bound by means of a saddle stitching machine Printing or paper works can be specified.

This task is accomplished with a saddle stitcher of the type mentioned Kind solved in that they have at least one in the direction of flow the transport device behind a feeder device arranged edge punching device. After this The inventive method is in such a saddle stitching machine first one consisting of at least one single folded sheet Sheet stack on a transport and / or processing device the saddle stitcher and then are first on at least one longitudinal edge of the sheet stack Punching out by means of in the conveying direction of the transport device arranged behind the placement of the sheet stack Edge punching device manufactured. Then another one Sheet stack on the previously punched the stack of sheets placed on the transport device, whereupon only the folding sheets of the further sheet stack, further punchings are produced which are compared to the Cut-outs in the sheet stack underneath in the longitudinal direction the stack are offset. This step is then followed repeated until the desired number of register openers in the magazine or the like. is made by what then the printing or paper works by putting on more uncut dies Sheet stack and / or stapling the one on top of the other Stack can be completed.

According to the invention, the saddle stitching machine known per se, such as those used in the production of large quantities, stapled magazines have long been common is expanded to include a function in addition to the previously known machine units with at least one edge punching device is provided with the individual punchings on the one after the other on the transport device filed sheet stacks are produced.

The transport device is preferably essentially from a transport collection chain and / or a collection sword Carriers for the sheet stack. A particularly advantageous embodiment the saddle stitching machine according to the invention results if several feeder devices each have an edge punching device assigned. With this arrangement, the individual thus, different stacks of sheets to be punched out Edged punching equipment so that the punching tools not to be set up for every new sheet stack must, since each punching device always has punched holes to be precise manufactures in the same place.

The edge punching device preferably has punching tools as well one arranged in the direction of flow in front of the punching tools Stack guide unit. The stack guide unit ensures for the sheet stacks being guided exactly to the punching tools so that their long edges are always exactly the right one Position under or between the punching tools, so that the cut-outs are always in the same, desired place getting produced. The stack guide unit can essentially the edge areas of the sheet stack from at least one the sheet guiding arrangement leading to the punching tools, the one with its fold over the collective sword or chain the hanging stack of sheets opens and in the area of the outer longitudinal edges so that the leaves of the sheet stack not in a hanging, but one approximately horizontal lying position are punched. So that the sheet stack when punching not from the transport device or the Lift off the stack guide unit and also the individual sheets of each stack of sheets do not move against each other can, the stack guide unit is preferably a sheet holding device assigned to the single sheets of a sheet stack holds each other safely. A particularly less prone to failure For example, sheet holding device can essentially consist of one pressure roller arrangement acting on the sheet stack and / or an upper and lower band guide exist between which the to punching sheet stack runs through.

The punching tools of the edge punching device are preferred on at least one, parallel to the direction of passage of the sheet stack aligned and the sheet stack in the area of one of his Longitudinal supporting punching table arranged for the Sides of the sheet stack to be processed in the area of their longitudinal outer edges forms a secure pad so that a clean one Punched out through all sheets of the stack. Particularly advantageous it is when the edge punching device on both sides of the Transport device one each the sheet stacks in the area of their Longitudinal supporting punching table with associated punching tools has, because then the sheets of the sheet stack Cut-outs on both outer edges at the same time usually used for the production of the service register are not in the same position on the longitudinal edges, but are offset against each other.

The punching tools are expedient in the direction of passage and / or transversely to the direction of the sheet stack adjustable. This makes it possible to determine the position of the punched-out area in the longitudinal direction and / or transverse to the longitudinal direction of a continuous sheet stack to change and so different registers to produce in printing or paper works. Of course you can the cutting edges of the punching tools must be interchangeable, too that punched out different cross-sectional shapes can be cut, for example, with a semicircular cross-section, rectangular cutouts etc.

It is particularly advantageous if the stamping tool essentially consist of at least one rotatably driven punch roll, with which very clean die cuts in the continuous Sheet stacks are generated. The punching tools preferably have one for the transport speed of the transport device synchronizable drive on, so that fluctuations in the Transport speed of the transport device has no influence to the position of those produced by means of a punching device Have die cuts.

It when the saddle stitching machine is a particularly advantageous arranged in the direction of flow behind the edge punching device, the transport device or the one transported with it Has sheet stack at least partially covering cover. After the punchings have been made in a first stack of sheets it is then transported on by the transport device and gets under the hood, so that a subsequent stack of sheets not immediately applied on the first stack, but on the covering hood above is launched. This makes it particularly easy to the next punched out only in the fold sheets of the second Manufacture sheet stack, since the single sheets of the first sheet stack under the cover in no case in the Punching tools for the second stack of sheets can get. Especially It is useful if the cover for a first Sheet stack in a sheet guide arrangement for a subsequent sheet stack passes over, which makes it structurally particularly simple Design results.

The saddle stitching machine preferably has a vacuum device on that of the stacking guide unit, the punching table and / or is assigned to the sheet guide arrangement and for this ensures that the sheets of the individual sheet stacks do not deviate from each other these components can take off, but as a result of the prevailing Vacuum can be sucked against this.

a product structure of the sheet stapled together in a magazine according to FIG. 1, which forms the mark-up register.

In Fig. 1, 10 denotes a program guide for television or Radio programs in which the broadcasts of the various Programs for a week specified on several pages each are. To open the reader of the program guide Facilitating programs on a particular day is the magazine in the area of its outer longitudinal edges 11 with an impact register 12 for the days of the week, which is why the pages The magazine punched out 13 different pieces for each day of the week Have length.

The magazine 10 shown in Fig. 1 is by means of a saddle stitching machine tied to its center fold 14 after the individual, also called sheet stacks for the magazine booklet as products by means of a collection and transport device of the Saddle stitching machine are merged.

Fig. 2 shows a schematic representation of part of a saddle stitching machine 15 how to assemble and staple the single sheet stack 16 of magazine 10 for use comes. In a manner known per se, the saddle stitching machine 15 a transport device 17 with a collective sword 18 from which Projecting fingers 19 protrude above, which on an inside of the Collection sword 18 arranged, rotating transport collection chain 20 are arranged. For each sheet stack 16 of those to be produced Program guide 10 is a separate investor facility 21 provided, in Fig. 2 only the feeder devices 21a, b are indicated for two different stacks of sheets. It However, it is understood that to produce the entire magazine more than two stacks of sheets on the seed stapler superimposed and stitched together and that in the machine also has more feeder facilities are. As will be described below, there is Magazine in the embodiment described here at least four sheet stacks or individual products with each at least two folded sheets around the opening register shown in FIG. 1 to create.

As can be seen from FIG. 2, the saddle stitching machine 15 in indicated by the arrow 22 through the direction of the Collecting sword 18 laid sheets behind the feeder device 21a an edge punching device 23, with the help of which those in the first one, placed by the feeder device 21a Sheet piles 16a to be produced are punched-outs 13. The next feeder device 21b for the second, sheet stack 16b to be placed and at least one further Such an edge punching device is assigned to the feeder device, which, however, are not shown in FIG. 2.

The edge punching device 23 has the longitudinal edges 11 of the sheet stack 16a assigned punching tools 24 and one in Passage direction 22 stack guide unit arranged in front of the punching tools 25 on, which essentially consists of two at the two Pages of the collecting sword 18 arranged sheet guide plates 26 exists. The sheet guide plates 26 are immediately behind the Feeder device 21a with its front edges 27 flush with the collecting bar 18 to start from there in the direction 22 stand out from the collective sword at an increasingly larger angle, so that the sheet stack 16a is transported along the gathering sword on its longitudinal edges 11 from the original, on the collective sword hanging downwards. At its rear end 28, the sheet guide plates go into one Punching table 29, which is horizontal on both sides of the Collective sword 18 extends and on its two outer edges 30 the punching tools designed as punching rollers 31 are arranged are.

Connect in the direction of flow behind the punching table this return plates 32 to the sheet stack after passage by the punching device back to its original position slide back on the collective sword in which the bows of the Hang the sheet stack approximately vertically downwards. Behind the return plates 32 is a collective sword 18 on its two Outer sides 33, 34 covering cover 35 arranged, the from two cover plates adapted to the contour of the collecting sword 36, which is arranged at a distance from the collective sword 18 are that the laterally drooping leaves of the previously through the edge punch 23 led sheet stack in those formed between the cover plates 36 and the collecting sword 18 Enter gap 37. The arrangement is however so hit that the sheet stack 16a in the area of its on top the middle sword 14 of the sheet metal lying between the collecting sword the cover 35 is not covered, so together with the the carrier fingers 19 transporting the stack from the top of the cover 35 protrudes. The cover begins in the direction of flow 22 of the transport device 17 in front of the following feeder device 21b and goes behind this in sheet guide plates 26b above that corresponding to the sheet guide plates 26a behind the first Feeder device 21a are configured.

3a to 3k can best explain how with the previously described saddle stitching machine in implementation of inventive method, the markup 12 on the Magazine 10 can be machined.

In a first process step, a first sheet stack is used for this 16a by means of the first feeder device 21a Collective sword 18 placed, one of the with the collection chain 20 circumferential driver fingers 19 on the rear edge of the Stacks 16a in the area of the middle fold 14 and so the sheet stack 16a lying on the sword in the direction of the edge punching device arranged behind it in the direction of passage 22 23 transported. The outer edges 30 of the Sheet stack using the sheet guide plates 26 from the in Fig. 3a shown, depending position raised (Fig. 3b) and thus come into an approximately horizontal position in which they Die tables 29 of the first edge punching device 23 rest. In the edge punching device, the sheet stack 16a is one arranged in the region of the central fold pressure roller arrangement 38 pressed against the collective sword from above, see above that he cannot stand out from this and his outer edges 30 exactly between the two sides of the collective sword on the outside Stamping tables 29 arranged punching rollers 31 run in. With help the punching rollers 31 are the punched-outs 12 of the first sheet stack 16a made on its two outer edges. This The method step is shown in Fig. 3c.

When the first stack of sheets is transported, it slides over the return plates 32 and thus return to their original, on the collecting sword before hanging under the cover plates 36 of the cover 35 in the between this and the Gathering sword 18 trained gap 37 (Fig. 3d). Subsequently with the help of the next feeder device 21b the second sheet stack 16b on the same driver finger 19 the transport device 17 is deposited, the cover 35 ensures that the sheets of the second sheet stack 16b in the area their outer edges separated from the first sheet stack 16a are held and so both sheet stacks with the same driver finger continue to be guided in the transport device, the second sheet stack 16b, however, in the area of its outer edges can be lifted separately from the first sheet stack 16a (Fig. 3e, f). Lifting the outer edges of the second stack of sheets takes place analogously to the first sheet stack with sheet metal baffles 26b, which are in a punching table of a second edge punching device 39 pass in which the punched out on second stack of sheets are made while at the same time under the cover 35 of the first stack of sheets transported without the tools of the second edge punching device 39 to be able to reach. The cover 35 ends with the punching table the second edge punching device 39 so that the second Sheet stack after making its punched-outs over the entire surface place on the first stack of sheets and close with it can put together a double stack. Once both sheets are stacked 16a, b lie one above the other, they come under cover plates 36 a further cover hood 40, on which then another sheet stack 16c with the help of another feeder device 21c and as it passes through the machine of another edge punching device is processed like this was previously described.

After the die cuts in the sheet stacks forming the register are produced in the manner described, on the product assembled in this way still further stacks and / or Cover sheet without punched out before the so compiled magazine in a known manner with the help of Staples are bound and then trimmed.

The punching tools of the individual edge punching devices 23 are adjustable on these and can both in Through direction as well as transverse to this can be adjusted, so that the location, length, width and / or even the geometric shape the die cuts can be changed. The punching tools or their drive is via a so-called virtual wave with the Drive of the transport device 17 synchronized, so that ensured is that the die cuts in the respective sheet stacks always made in exactly the same, correct place become.

Fig. 4 shows the product structure for that in the program guide 10 proposed markups. After that point the first three sheet stacks 16a-c after their passage through the respective Edge punching device 30 punchings on both outer edges 13, with all punched-outs different Length after the individual stacks have been put together to be able to educate.

The fourth, last placed sheet stack 16d points at it right half of the sheet no punched out, while the left half of the sheet cut off on its outer edge 30 over the entire height and so after placing it on the first stack of sheets the left half of the fourth sheet stack 16d the first Section of the service register 12 forms.

The invention is not based on that shown and described Embodiment limited, but there are many Changes and additions without going beyond the scope of the invention leave. So those made with the help of the punching device Die cuts do not have the rectangular shape shown Have design and it is not necessary that the Die cuts always extend to the bottom edge of the sheet stack. For example, it would be conceivable, for example, semicircular punchings to produce at the edges of the sheet stack, the Die cuts in different stacks are staggered are. Of course, registers can also be made with the invention with more divisions, for example letter registers in address directories or the like, where then the Number of feeder devices and edge punching devices must be increased accordingly.
