Description

The The invention relates to a cross cutter for processing webs according to the preamble of claim 1.

It is known, the web-shaped Substrates for Sheet processing machines by means of a cross cutter arcuately divided and the sheet processing machine can be fed.

bow processing machines process sheets cut to sheets, which is used in batches in a feeder and separated from there is transported through the machine in bends. Come here Sheetfed presses, stamping machines, laminating machines, painting machines, Sorting and gathering machines or facilities for performing a quality control or other similar further processing machines in question.

Sheeter have been so far for the division of unprinted web-shaped substrates in combination with stacking devices for producing raw sheet stacks or in conjunction with sheet-fed rotary printing machines for the direct supply of used for printing sheets.

adversely on the sheet-fed rotary printing press, that is for a series of manufacturing processes has a lower performance and in the Usually set to the provided on a stack sheet material is.

Farther is disadvantageous that the manufacturing methods mentioned above not or only with great Effort within a printing machine are feasible and easy Printed products usually too expensive Require devices.

task The invention is therefore, for inexpensive Printing processes in a simple way, a further processing option available close.

The solution This object is inventively according to the features of claim 1. Advantageous embodiments emerge from the subclaims.

to Processing of substrates in a wide variety of formats it intended to wrap the substrates in web form and for the preparation to leave the processing. When the processing is done should, the product rolls are used in a sheeter. The sheeter may be involved with a sheet processing machine associated with a further processing device.

The Processing is preferably carried out in a printing station for the upper and the bottom of the substrate. In this way arose compact and inexpensive Plant for the production of simple, double-sided printed products.

The Copies can be edited directly after cutting. To be used can e.g. following application methods: painting, laminating, laminating, Punching, embossing, Creasing, Folding, Sorting, Gathering, Stapling, Riesling, Quality control.

In Advantageously, the cross cutter with an additional Schupp station be provided such that the processing in the sheet machine to be applied at the right speed and in the right direction Distance from each other can be.

Advantageous on the device is that the substrate directly from supply rolls in sheet-processing machines on an application basis simple level can be processed.

in this connection come in addition if necessary, additional coating operations in question. Furthermore, the substrate can already by embossing or cutting Finishing processes are refined.

Further advantageous characteristics The invention will become apparent from the dependent claims.

in the The invention will be described below with reference to drawings example closer explained.

in this connection demonstrate:

1 a diagrammatic representation of a first embodiment of the inventive device,

2 a variant of the inventive device with a separate sheet feeder, and

3 a variant of the inventive device with additional shingling unit.

In 1 is a role changer 1 a web guiding unit 2 downstream. This leads the printing substrate B to a sheeter 3 , In the cross cutter 3 single sheets are cut from the substrate web B and ordered to a scale flow S.

Within the arc current S is for the Arc creates a so-called scale distance, which refers to the distance of the leading edges, lying in the scale flow S arc. This scale spacing depends on the requirements of further processing.

This includes the sheeter 3 a cutting unit 9 and a shed station 8th which can produce a shed spacing specific or variable to the cross cutter. The one from the sheeter 3 Outgoing shingled stream S of bow is conveyed over a conveyor 4 in a sheet feeder 5 a sheet-processing machine further promoted.

From the speed ratio of the conveyance of the sheet flow S via the conveyor table 4 and the cycle of removal via the sheet feeding device 5 in the sheet-processing machine derives the above scale spacing.

When Sheet processing machine is a printing press provided. This can also be used as a painting, laminating or laminating machine, punching or embossing machine or a similar one Further processing or finishing device configured or be equipped with appropriate processing modules in addition.

The sheet processing machine includes a sheet feeder 5 , at least one printing station 6 and a sheet delivery 7 , By means of the sheet feeding device 5 the sheets are supplied from the shingled stream S individually in fitting assignment to the sheet-processing machine.

The printing stations 6 consist of an upper printing unit O and a lower printing unit U. The printing units O, U can be configured as offset printing units and then have at least - not shown here - color and dampening units, a form cylinder and a blanket cylinder. Depending on the configuration can be provided per printing unit U and / or O and a counter-pressure cylinder. The arrangement shown is designed so that two blanket cylinders are in contact with each other. Here, the sheet is carried out between the blanket cylinders and simultaneously printed on both sides. This results in monochrome printed products on both sides. Such products are versatile in use as simple supplements to packaging.

After passing through the printing stations 6 the sheets are in a sheet delivery 7 merged into stacks, bundles, giants, or otherwise configured arcs.

The substrate roll to be processed may have been pretreated in other processing units. Here, not only conventional printing processes, but also coating methods such as priming or painting or the like come into question. The format of the use of the printing material web B determined by the configuration of the processing units is in the cross cutter 3 easy to process. The sheeter 3 Ensures that the exiting single sheets can be transferred in an orderly sequence to the downstream sheet processing machine.

The sheet feeder 5 may comprise a Saugbandstrecke, which transports the sheets in a fixed orientation, since the sheets in a timed sequence with a defined distance in the sheet feeder 5 the sheet processing machine must arrive. Usually, the supply is as unterschuppter sheet flow, but it is also possible sheet feed.

• – Rollenträger (hier ein Rollenwechsler 1)
• – Bahnführung (hier eine Bahnzuführung 2, als Speicheraggregat mit Bahnschleifen ausgeführt z.B. mit Bahnkantensteuerung)
• – Querschneider (hier ein Querschneider 3, Schneidaggregat 9)
• – Bogenschuppung (hier ein Schuppaggregat 8)
• – Bogenzuführung (normalerweise in Bogenrotationsmaschinen integriert).

Preferably, a so-called roll-bow feeder is used for sheet feed for the sheet-processing machine. The roll-to-sheet feeder has hitherto been designed as a feed unit of unprinted substrate for sheet-fed rotary printing presses and has the following features

• - Roller carrier (here a reel changer 1 )
• - Web guide (here a web feed 2 , designed as storage unit with track loops eg with web edge control)
• - Sheeter (here a sheeter) 3 , Cutting unit 9 )
• - Archery (here a shingling unit 8th )
• - sheet feeder (usually integrated in sheet-fed rotary machines).

If the reel-bow feeder is so arranged on rails that he is displaceable from the area of the sheet-processing machine, can a conventional supply via the sheet feeder means Sheet pile done.

The Function of the roll-bow feeder is also for the processing of foils suitable. He can for this purpose with an antistatic attachment or Corona facilities be provided for the pretreatment of the film surface.

For processing From paper, the roll-bow feeder can also be a rewet contain.

Above all, the advantage of the system thus created is that a wide variety of substrates for simple products can be processed cost-effectively, the starting material being inexpensive to obtain. Furthermore, possibly omitted transport and storage capacities through the direct transition from the processing units in the Sheet-fed rotary printing press.

Sheeter 3 For example, the sheet-processing machine can be assigned in a so-called in-line arrangement, ie in a straightforward assignment before the sheet feed of the sheet-processing machine with respect to the conveying direction of the printing material. The sheeter 3 but can also be connected in a rectangular arrangement with the respective sheet processing machine, the sheet feeder then via a so-called corner conveyor with those of the cross cutter 3 supplied sheet is supplied. Then, however, the cut sheet material must be transported across its unwinding direction by the sheet processing machine.

• a) Die Bogen verarbeitende Maschine kann mit standardmäßigen Bogenanlegern für die Verarbeitung von Bogenstapeln aus Papier, Karton, Kunststoff oder anderer Materialien genutzt werden.
• b) Die Bogen verarbeitende Maschine kann mittels des Querschneiders 3 mit dem einfachen Schuppaggregat 8 oder dem zusätzlichen Schuppaggregat 20 für Verarbeitung von Rollenmaterial aus Papier, Karton, Kunststoff oder anderer Materialien genutzt werden.

This type of assignment of sheeter 3 and sheet processing machine allows a dual use:

• a) The sheet-fed machine can be used with standard sheet feeders for processing sheet stacks of paper, cardboard, plastic or other materials.
• b) The sheet-processing machine can by means of the cross cutter 3 with the simple shovel unit 8th or the additional shingling unit 20 used for processing roll material made of paper, cardboard, plastic or other materials.

For the configuration variants after the two aforementioned cases is the sheet-processing machine always additionally with a sheet feeder equipped, but the system is more expensive.

In addition, in the event that only web-shaped materials are to be processed, but also the following arrangement conceivable: Inline arrangement of the cross cutter 3 ie in the running direction of the paper run, the sheeter with a shingling unit can promote the shingled sheet flow directly into the plant of the sheet-processing machine and the arrangement of a sheet feeder is eliminated.

• a) Das Schuppaggregat 8 des Querschneiders 3 liefert die für die Bogenanlage in der Bogen verarbeitenden Maschine erforderliche Schuppenabstand (siehe 2).
• b) Das Schuppaggregat 8 des Querschneiders 3 liefert einen beliebige Schuppenabstand, wobei aber eine zusätzliche Schuppstation 21 (vergleichbar dem Bogenanleger), z.B. mittels einer Walzengruppe mit Förderrollen, den für die Bogenanlage in der Bogen verarbeitenden Maschine erforderlichen Schuppenabstand erzeugt (siehe 3).

In this context, the following configurations of the assignment are possible:

• a) The shovel unit 8th of the cross cutter 3 provides the shed distance required for the sheet processing in the sheet processing machine (see 2 ).
• b) The shingling unit 8th of the cross cutter 3 provides any scale spacing, but with an additional shingling station 21 (Comparable to the sheet feeder), for example by means of a group of rollers with conveyor rollers, the required for the sheet processing in the sheet processing machine shed distance generated (see 3 ).

In 2 is the first of these variants shown. The sheeter 3 delivers the sheet flow S in the preset scale distance X on a conveyor table 10 , From there, the scale flow S is possibly via a belt table 11 supplied with the scale distance X of the sheet processing machine.

In 3 is the second of these variants shown. The sheeter 3 delivers the sheet flow S in its own scale distance X via a conveyor table 20 to a shed station 21 , There, the scale flow S is reconfigured to a scale distance Y. This can be, for example, a single sheet funding. From the Schuppstation 21 If necessary, the scale flow S via a belt table 22 supplied with the scale spacing Y of the sheet processing machine.

In the embodiments according to 2 and 3 No conventional sheet feeder is provided.

Scroll-to-sheet cross cutters have hitherto been used mainly on sheet-fed rotary offset printing presses. The described arrangement also allows use on the sheet complementary processing machines, such as

• - folding / stapling machines,
• - punching / embossing machines,
• - laminating / laminating machines
• - Sorting systems and / or
• - quality control equipment.

• – Inline-Anordnung
• – rechtwinkelige Anordnung

A register-cutting device for roll-to-sheet cross cutter is necessary to obtain exact sheet dimensions for further processing in the sheet processing machine. Again, there are two variants of the assignment of cross cutter and sheet feeder or sheet processing machine:

• - Inline arrangement
• - rectangular arrangement

Further embodiments of the invention can be found in the application of individual drives for the cross cutter 3 , the conveyor table 4 and or 10 and or 20 , the shingles 8th and or 21 , the cutting unit 9 , as well as the belt tables 11 and or 22 , By means of individual drives a very variable tuning of the aggregates to each other is possible, in particular with regard to the producible scale distance.
