Description

The invention relates to a strand mixing device and a method for mixing strands according to the preamble of claim 1 or 13.

The invention relates to a strand mixing device which can be used in newspaper printing between a printing machine and a transverse folding apparatus in order to bring a plurality of printed paper webs into a desired order for the finished printed product. In particular, the invention relates to a strand mixing device which is suitable for printed products in tabloid format.

The DE 43 26 855 A1 discloses a strand mixing device with a former and two guide paths, on each of which a longitudinally cut partial web is guided, wherein one of the partial webs provided on its way with glue and then adhered to the other partial web. In another embodiment, two strands run over two formers, wherein one of the strands is glued by a stapler and the other strand in the manner mentioned, before they are both taken together to form a main strand.

By the DE 43 44 362 A1 a strand mixing device with at least one former is known, wherein the strand leaving the former can optionally be guided around one or the other side of an underlying further former.

In the DE 41 28 797A1 is a funnel construction with several, arranged in different hopper levels formers known. Strands folded by means of an overhead hopper can optionally down on one side or the other of an underlying former to a downstream folder be guided.

The invention has for its object to provide a strand mixing device and a method for mixing strands.

The object is achieved by the features of claim 1 and 13, respectively.

The advantages that can be achieved with the invention are, in particular, that the strand mixing devices allow the production of multi-layer products, in particular tabloid products, wherein at least one layer of the product is tacked.

Another advantage is that the strand mixing devices manages without turning bars.

This reduces the cost of the device. In addition, the collection of material webs to be processed into the device before their commissioning is easy and quick to carry out. Eliminating turning also reduces the susceptibility of the line mixing device to breakdowns.

In this case, the strand mixing device has at least one second former and a guide path for guiding a second sub-string from the second former to the output. With such a device, a sub-strand of the strand cut by the slitter can be mixed with the second sub-strand from the second former to a first book, while the other sub-strand of the cut by the slitter strand is stapled and results in a second book.

Preferably, a folder is connected to the output of the strand mixing device. With the folder can be made from out of the Strangmischvorrichtung emerging strand tabloid products finish.

An embodiment of the invention is illustrated in the drawings and will be described in more detail below.

Product examples a) to m) for the above examples and the embodiment.

The examples of Fig. 1-3 are not covered by the claimed invention, but are useful for understanding.

An in Fig. 1 strand mixing device 01 shown comprises two formers 02; 03, guide rollers 04; 06; 18, two slitter 07; 08, pulleys 09; 11; 12; 13; 14; 16, two draw rollers 05; 10 and a stapler 17. To the strand mixing device 01 a folder 19 is connected, which has a cylinder 21, z. B. cutting cylinder 21, a cylinder 22, z. B. Schneidnut-, Punktur- and folding blade 22 and a cylinder 23, z. B. jaw cylinder 23 includes.

Through the former 03 is a strand 24 in the direction of the arrow drawn. The strand 24 is a plurality of parallel running printed paper webs 24 that are processed together into tabloid products. During the passage through the former 03, the side by side on the former 03 running, longitudinally cut partial webs are brought together. Subsequent to the former 03, the folded strand 24, in this case strand 24 having successive partial webs, passes through guide rollers 06 and opens into the draw roller 05; 10 or Zugwalzengruppe 05; 10. The strand 24, after passing through the former 03, thus consists of a double number of parallel running paper webs 24, which, however, have a smaller width than the paper webs 24 before opening into the former 03. About the deflection rollers 14; 16, the strand 24 is guided to the guide rollers 18 and leaves over this the strand mixing 01.

Accordingly, a strand 26 is introduced into the former 02, which also consists of a plurality of parallel-running paper webs after longitudinal cutting and successive feeding. This strand 26 may, for. B. may be obtained together with the strand 24 by longitudinal cutting a double-width, printed in a printing machine strand before entering the strand mixing device 01.

In the former 02, the partial webs of the strand 26 are brought to each other and after leaving the former 02 on the guide rollers 04, the tension rollers 10; 05 supplied. The strand 26 is after leaving the draw roller 10; 05 of the guide roller 09, where he in contrast to the strand 24 in two sub-strands 27; 28, z. B. paper webs 27; 28 is split.

The sub-strand 28 is guided by the deflection roller 09 via the deflection roller 11 to the guide roller 18, ie to the output of the strand mixing device 01. Here he unites with the strand 24. Since the strands or partial strands 24; 27; 28 are guided towards each other in the region of the guide rollers 18, the location of the merging in the region of the guide rollers 18 is referred to as the output here, although he also considered purely structurally can lie downstream.

The sub-strand 27, however, runs from the guide roller 09 to the stapler 17. The stapler 17 staples the sub-strand 27 forming webs 27 - even before he enters the folder 19 - each along a line between two sides of the printed image generated thereon, at the later upon passage of the strand 27 through the folder 19, a transverse fold will be created. After leaving the stapler 17 is now composed of paper webs 27 stitched existing sub-strand 27 on the pulleys 12; 13 also leads to the guide roller 18 and combines there with both the sub-strand 28 and the strand 24. Thus, the output of the strand mixing device 01 forming guide rollers 18 leaves a main strand 29, resulting from the ungestetierten paper webs of the strand 24, the unwoven paper webs 28 of the sub-strand 28 and the stitched paper webs 27 of the sub-string 27 composed.

This main strand 29 runs between the cutting cylinder 21 and the Schneidnut-, Punktur- and folding blade 22 of the folder 19 a. At the Schneidnut-, Punktur- and folding blade 22, a jaw cylinder 23 connects. Between the cylinders 21; 22 of the folder 19, the main strand 29 is cut in a known manner into individual products, which are then between the cylinders 22; 23 are cross-folded. The tabloid products made with the strand mixing device 01 shown have an outer non-stapled layer and an inner stapled layer.

Since the paper webs 26 of the strand 26 can be arbitrarily distributed to the partial strands 27, 28 on the deflection roller 09 and a paper web 26 corresponds in each case to four sides of the finished printed product, the handling of the stapled position in sections of four pages is arbitrary.

The strand mixing device 01 is not limited to the illustrated specific embodiment. Thus, for example, it is possible to modify the strand mixing device 01 in such a way that the stapling device 17, instead of being arranged in the guide path of the partial strand 27, is arranged in the guide path of the partial strand 28. Then the paper webs forming the sub-strand 28 are stitched together at predetermined locations by the stapler 17, while the paper webs 27 forming the sub-strand 27 remain unstacked. After merging the partial strands 27; 28 with the strand 24 to the main strand 29 at the exit of the strand mixing device 01 at the guide rollers 18 and after passing through the folder 19 are produced with this alternative embodiment of the strand mixing device 01 tabloid products, which have three layers, with an outer and an inner layer are untied while a layer located between these two layers is stapled.

Of course, the strand 26 could also be completely, possibly together with branched off from the strand 24 paper webs, are guided by the stapler 17 when the stapled position a greater extent than desired for the unstapled.

Depending on the width of the strand mixing device 01 upstream printing machine, the strand mixing device 01 may also have more than two formers, then the guided through the stapler 17 sub-strand may be part of a resulting from one of the former longitudinally cut strand or even this strand completely and additionally paper webs may comprise a strand originating from an adjacent former.

In another embodiment of the or are the slitter 07; 08 not in front of the former 02; 03, but after the former 02; 03 arranged. In this case, the folded strand 26 after the former 02; 03 cut open at the seam back.

In an in Fig. 2 Example shown are a former 02 and the above formed strand 26 at least two strand guides of sub-strands 27 and 28 assigned. The strand 26 is this before (or after the former 02 as above) cut longitudinally and then split on the strand guides of the partial strands 27 and 28. At least one of the strand guides, but advantageously both, in this case has on its way to a stapler 17. One or both of the partial strands 27; 28 may or may be stapled before they are combined again to form a product and further processed in the folder 19.

As indicated by dashed lines, a third sub-strand 31 can be led out of the strand 26, and stapled by a possibly present stapler 17, before this is again taken to product together. Likewise dashed is a strand guide, wherein a partial strand 32, for example, without deflection and / or without stapling straight down to the inlet into the folder 19 is performed.

A particular advantage lies in the execution Fig. 2 in that for several separately stapled or partially unstitched "books" of a product, the number of formers 02; 03 is significantly reduced. For example, with similar product variability, an additional hopper (balloon hopper), which is otherwise arranged above the former 02, can be saved. As a result, significant construction costs and height can be saved.

In a third example ( Fig. 3 ), the two strands 27; 28 from the former 02 to both sides of a z. B. underlying Former 03 via pulleys 09; 09 'led. On one or both strand guides of the strands 27; 28 may be arranged as in the former examples, a stapler 17 (shown in phantom). The two strands 27; 28 are performed in front of the folder 19 with the strand 24 from the lower former 03, the latter comes to rest between the first two. In an advantageous embodiment, in addition to or instead of the stapler in the strand guide of the strand 24 Staplers 17 a stapler 17 'may be arranged. In an embodiment characterized by a high degree of flexibility, both the strand guide of the strand 24 and at least one of the strand guides of the strands 27, which circumnavigate both sides of the former 03, have branches 27; 28, a stapler 17; 17 'up. If it should be possible to produce more variable, the strand guides of the three strands 24; 27; 28 each have a stapler 17; 17 'up.

In all three examples can be exemplified in Fig. 3 indicated additional bypass strand guides 33; Be provided 34, by means of which a present on a strand guide stapler 17; 17 'with a part of -. B. again divided - strands 24; 27; 28 or with the entire strand 24; 27; 28 is feasible without stitching. In Fig. 3 For this purpose, only two bypass strand guides 33; 34 indicated without dashed pulleys etc. indicated by dashed lines. However, these are in development on individual, several or all strands 24; 27; 28 optional transfer from the three examples.

In a first embodiment ( Fig. 4 ) are two formers 02; 03, each with a slitter 07; 08 each a stapler 17; 17 'in the guide path from the respective former 02; 03 assigned to the output of the strand mixing device 01. The strand mixing device 01 in this case has pulleys 09; 14; 36; 37, via which a partial strand 28 or the entire strand 26 of a former 02 by the second former 03 associated stapler 17 'together with a sub-strand 27' or the entire strand 24 of this second former 03; 02 is guided feasible or in an advantageous embodiment. In a superstructure, not shown, therefore, must not already be determined by turning of partial webs correct for stapling funnel bake, but partial web can pass through the former 02; 03 nor the other to stapling sub-strand 27 'or strand 24 are added. It can also all partial webs, ie both folded and cut strands 24; 26 via one of the staplers 17 '; 17 to be processed into a product. Likewise is it is possible for one sub-strand 28 to be stapled together with one strand 24 or sub-strand 27 'of the other former 03, while the remaining sub-strand 27 of the first former 02 passes through the associated stapler 17 without stapling (ie, stapler not inoperative or out of service). The arrangement with the mentioned reference numbers is to be applied symmetrically to the reverse guide.

Through said guide paths on the two staplers 17; 17 ', a main strand 29 is obtainable at the exit in a first mode of operation which comprises a part with one or more non-stitched layers (eg stopped stapler 17, 17') and a part with several layers stitched together ( Fig. 5 a) , shown from inside to outside). In a second mode of operation ( Fig. 5b) ), the main strand is formed by two parts each having a plurality of stapled layers having parts, wherein the number of layers between the two parts can be variable by the above transfer.

Advantageously, the strand mixing device 01 further deflection rollers 11; 16, via which a sub-string 28 as required; 28 'of the one and / or the other former 02; 03 without passing through one of the staplers 17; 17 'along a corresponding guide path between the two staplers 17; 17 'is passed through the output or are.

In this way, the above-mentioned operations and resulting products on the main strand 29 can be extended to the effect that in a third mode of operation in addition to the above sequences in the parts between the two parts already mentioned - in particular the two stapled parts of the second mode of operation - in addition a part with a or several un-stapled layers ( Fig. 5c) ). Number and origin of the position (s) of this latter part is variable, they can / from one, the other or both Former 02; 03 come.

Even more flexible in the product to be produced is the strand mixing device 01 with further Pulleys 09; 09 ';10; 10 ';11; 12 executed, via which a sub-string 27; 28; 27 '; 28 'at least one of the former 02; 03 without passing through one of the staplers 17; 17 'on an outer side of the strand mixing device 01 around the two staplers 17; 17 'can be carried around to the exit. In Fig. 4 is 02 for each of the two formers; 03 such a subsequent as a bypass strand guide 33; 34 designated guide provided. This allows in addition to the first two modes of operation and the third mode of operation, that the respective sequence of parts on the one and / or the other strand outside of the main strand 29 now obtained can be added or added another part with one or more non-stitched layers , For example, in a fourth mode of operation, a sequence of a stitched portion, a stitched portion, a stitched portion, and a second stitched portion (FIG. Fig. 5 d) ), and in a fifth mode of operation additionally a further untied part ( Fig. 5 e) ) possible or produced. In a sixth mode of operation, a sequence of a non-stapled portion, a stapled portion, and a second stapled portion (FIG. Fig. 5 f) ), and in a seventh mode of operation, additionally a further untied part ( Fig. 5g) ) achievable or produced.

The said pulleys 09; 11; 12; 13; 14; 16; 36; 37 are as rollers 09; 11; 12; 13; 14; 16, in particular as driven only by friction rollers 09; 11; 12; 13; 14; 16 executed and serve the leadership.

In the folder 19, the main strand 29 is cut transversely into product sections and the product sections thus obtained, for example, transversely folded.

The transverse folded products which can be achieved for the abovementioned modes of operation are exemplified in US Pat Fig. 5 a) to g) shown. The number of layers per part (stapled or unstapled) is chosen here only as an example. However, the number of layers in the part may be lower or higher than shown. Different parts may have different number of layers. Especially for untightened parts, the number of Also be 1 A stitch is indicated by a line connecting the layers in the region of the fold back.

In Fig. 5 among other things, the by various modes of operation of the device according to Fig. 1 achievable products shown. Fig. 5 a) shows a product where z. B. a transfer of a not provided for stapling partial strand 28 takes place.

Also in Fig. 5 include, but are not limited to, the various modes of operation of the device Fig. 2 removable. For example, with only the solid strands 27; 28 the product according to Fig. 5 a) (a stapler turned off) and Fig. 5b) achievable. Without consideration of a leadership of the sub-string 31 - as in a basic version of the execution according to Fig. 2 is provided - but with the possibility for the sub-strand 32 is Fig. 5c) producible. With the sub-strand 31 (without the guidance of a partial strand 32) is in existing left stapler 17, parked or nonexistent middle and employed right stapler 17 also Fig. 5c) , and additionally employed middle stapler 17 Fig. 5 j) achievable. However, if the left stapler 17 instead does not exist or is turned off, it is Fig. 5 m) realizable. Fig. 5h) shows a possible, by all drawn guides and the three (employed) staplers 17 product produced.

In addition to those in the description section too Fig. 4 mentioned products ( 5 a) to 5 g) ), but to be transferred to operating situations with selectively parked or not provided staplers 17; 17 'or used or unused bypasses 33; 34) is with the device after Fig. 3 considering the bypass 33 and three staplers 17; 17 'a product after Fig. 5 i) , and without bypass 33, but with bypass 34, the inversion of the product Fig. 5h) , Assign all three solid strands or partial strands 24; 27; 28, a stapler 17; 17 ', so is without further bypass 33; 34 the product according to Fig. 5 j) made of three parts. Is only for the Strand 24 a stapler 17 'provided (or alternatively only this of two or three staplers 17, 17' employed, so results in a product according to Fig. 5k) ,

However, the order in the representation from the inside to the outside are reversible either by appropriate guidance by the strand mixing device 01 or by a change of the folding apparatus 19.

It is particularly advantageous that the products mentioned are usually at least largely without, in particular without previous turning of partial webs in a superstructure before the formers 02; 03 are produced. The one or the other strand or sub-strand 24; 27; 28 to be assigned partial webs are transferred in the strand mixing device 01 to the desired location.
