Description

The invention relates to blank sheets and a blank sheet separation machine and manufacturing plant for the production and further processing of sheet-shaped packaging material to blanks or packaging solutions.

In order to pack, portion, store, and the like various goods, products, foods, and other items requiring protection, a variety of packaging solutions varying in their characteristics, configurations, and techniques are employed. Arc-shaped packaging materials based on cardboard materials are used as starting material for outer packaging, folding cartons, beverage and food carton packaging and so on.

In the packaging of any materials, consumables, powdery and lumpy substances or elements folding cartons, wrappings or corrugated cardboard packaging have proven. In addition to the wrapping of the substance to be packaged, frequently asked requirements for the packaging solutions based on sheet-shaped packaging materials are, for example, the reduction of external environmental impacts on the product to be packaged, dimensional stability in support of stacking operations and handling due to intrinsic stability. Packaging solutions of this type can be in direct contact with liquid, solid or flowable foods as well as be used in the context of overpacking solutions that have no direct contact with the goods to be packaged. Various applications are possible: packaging of goods, food and so on in the household and / or industrial sector, for representative purposes such as sales boxes and the like.

Folding cartons, wraps or corrugated paperboard packages may be formed based on various materials and / or configurations such as uncoated sheet-like corrugated board, printed variants, single-side coated, laminated and / or lacquered form. Furthermore, conceivable arcuate boards on both sides with a coating on both sides with several coatings such as polyethylene (PE), polypropylene (PP) and / or aluminum (AL).

Can be combined the aforementioned material bases of cartons, wrappings or corrugated cardboard packaging with features such as score lines for easier folding later, opening aids such as perforations for tearing, openings and / or recesses to see the packaged product or recesses which are later closed again with a Foil to realize so-called window packing.

• - ein oder mehrere Löcher mit oder ohne durchgehende PE- und/oder PE/AL-Schicht,
• - bereichsweise Perforationen im Karton mit wenigstens bereichsweiser oder durchgehender PE- und/oder PE/AL-Schicht,
• - ein oder mehrere Löcher im Karton mit oder ohne durchgehende PE- und/oder PE/AL-Schicht, welche optional mit einer Verschlusskappe verschlossen und wieder geöffnet werden können.

If coated folding cartons are used for liquids, they may have an additive or alternative

• one or more holes with or without a continuous PE and / or PE / AL layer,
• - Perforations in the cardboard with at least partially or continuously PE and / or PE / AL-layer,
• - One or more holes in the box with or without continuous PE and / or PE / AL layer, which can optionally be closed with a cap and opened again.

In the packaging and / or portioning of foods and in particular pourable or flowable foodstuffs such as juices, teas, milk, soups, sauces, powders, granules, glass containers, plastic bottles, tubular bags, blister solutions and cardboard packaging are provided as packaging solutions.

Cardboard-based packaging solutions for flowable or pourable products basically have the task of reliably picking up, storing and releasing the product to be packaged, at least temporarily. If the pourable or pourable products to be packaged are foodstuffs in the broader sense, further requirements can be added to the packaging solution. These include, in particular, protective functions that at least temporarily store the food in such a way that the food occupies or maintains the properties and conditions required for consumption.

An important protective function in this context is the reliable removal of mostly external influences on the packaged food. Very important for the durability, that is, the maintenance of food-biological properties at the time of packaging is the protection against harmful microorganisms such as germs, spores, unicellulars and so on. When germs come into contact with the food in question, biological processes are triggered which lead to spoilage of the food and thus to inedibility.

Another important protective function with regard to exposure to light, and in particular also its formation in various electromagnetic wave spectra, may be required depending on the food to be packaged. For example, light effects can cause infrared or Ultraviolet light sensitive vitamins and other ingredients are destroyed, reducing or degrading the quality and nutritional value of foods. Light effects can also cause unsightly and unappetizing discoloration.

If cartonage-based packaging solutions are used for flowable or free-flowing products and in particular foodstuffs, measures must be taken to implement the necessary protective functions.

Cardboard as the primary material for cartonage-based packaging solutions is a basic material made of pulp, waste paper and / or wood pulp of various types of wood, which does not support, not readily or inadequately, the aforementioned protective functions.

In order to implement at least one of the protective functions in cartonage-based packaging solutions and / or to produce the characteristic of hermetic tightness which is important for liquid or flowable products or foods, multilayer so-called packaging materials for such packaging solutions are created. In the case of these packaging materials, the cardboard serves as a primary material practically as a carrier and base material for realizing the mechanically required properties and / or the structural integrity. The cardboard is supplemented by at least one coating material applied on one or both sides.

Coating materials for realizing, for example, a light barrier to prevent or reduce exposure to light may be aluminum. Aluminum in various forms, for example as a web or sheet, as vapor-deposited particles or dissolved in a suspension can prevent the action of light when the layer thickness is sufficient.

Coating materials for the realization of, for example, a hermetic packaging material impermeability can be formed from various plastics such as polyethylene (PE), ethylene-vinyl alcohol copolymer (EVOH) or polypropylene (PP) and have barrier and / or adhesion promoter properties to varying degrees. Additively or alternatively, plastic-based coating materials can impart further functional properties to the carton-based packaging solution or to the packaging materials, such as good printability, surface properties, surface finishes, and the like.

Among other things, the mechanical properties of paperboard materials depend on the base material, the type of wood used, the fiber orientation, the respective production steps, the added additives, the material density or its grammage and the material thickness and can also be local due to fiber types, density and their orientation Material vary with the result that there is an at least partially and directionally anisotropic base material.

In addition to the aforementioned tasks, characteristics and requirements for packaging solutions for various goods, products, food and other items requiring protection, it may be necessary to achieve the opening of the packaging solution and / or the resealing of the packaging in the case of only partial removal of products. For this purpose, various variants are used which correspond to the basic idea of influencing or modifying the mechanical properties and / or the structural integrity of the strength-determining base material cardboard in a targeted and partially limited manner in a manner suitable for the opening and possibly the (re-) closing.

Often, the opening or closure assisting modification is a partial weakening of the strength properties and / or removal of a patch of the basestock.

A first variant may be, for example, to remove a surface piece, usually in the form of a circular hole, before coating the base box therefrom. Subsequently, the required coating materials are applied over the whole area, that is to say above the cardboard and the removed surface area. In this way, the packaging material is partially modified in an opening and / or closing-supporting manner. This modification is particularly advantageous in the use of opening aids, closures and in particular screw caps or drinking straws, which interact with the partial modification.

Another variant supports the opening of the packaging solution by the partial weakening of the packaging material or of the at least partially coated base cardboard to a packaging material. For this purpose, a perforation of different geometrical design is introduced into at least two layers of the packaging material or of the packaging material. Preferably, the perforation is provided in the base board or in the base board and at least one coating material. In order to maintain the barrier properties with respect to exposure to light, it may be advantageous not to perforate the aluminum coating.

The production of packaging material takes place in a variety of manufacturing steps, starting from a base box, which is usually available by the meter on a roll. The dimensions of such cardboard rolls can be more than 1000 mm in width and several thousand meters in length, so that a variety of blanks in the longitudinal and transverse directions of the meter goods can be applied.

An arc or packaging material sheet is used when a partially or completely constructed packaging material with coatings of the piece goods is separated in such a way that several blanks of the preferably rectangular sheet are included. From a blank one speaks at a isolated packaging material section for subsequent packaging, which is further processed by a longitudinal connection to a shell and additionally processed by closing on the front side to a (closed, semi-open or open) packaging.

The variety of manufacturing steps for the production of packaging material is often in systems with multiple processing stations. For this purpose, various production step sequences are provided, which require the transport, handling and / or intermediate storage of production step results, that is partially processed packaging or packaging material.

In order to realize packaging weakenings such as holes, cuts or perforations with different geometrical configurations (for example so-called cuts, webs or half-cut), different production methods and tools are used, for example laser cutting or mechanically based perforation insertion by rotationally moving stamped sheets or segments or by linear motion kinematics, for example on one flatbed die cutter.

Packing weakenings at various stages of packaging material production and / or before filling a packaging solution with a product to be protected can be introduced. For this purpose, slitters, coating equipment, printing machines, stamping machines, longitudinal seaming machines, rewinders, sheeters (that is to say roller sheet-cutting machines) and / or filling machines can be equipped with correspondingly suitable devices.

A possible production step sequence described by way of example below may be that weakenings in the form of holes are first introduced into the base or raw cardboard present in web form on rolls.

The sheet-like paperboard starting material is fed from the raw paperboard roll in a preferably continuous unrolling process to a coating machine with a rotary punch and one or more holes are punched next to each other and / or in the roll length into each subsequent pack blank. The roll width usually corresponds to a plurality of package heights and the roll length of the package width.

The introduction of holes into the green cardboard web realized after a hole punching in the first station of a coating installation can be supplemented by subsequent coating steps. This means that the perforated cardboard roll is coated with one or more layers and wound up into a roll with a predetermined winding characteristic. This winding orientation, that is, the respective position of the coatings on the outer or inner diameter of the roll to be wound can be carried out depending on the coating material. Usually one differentiates with regard to this criterion between plastic coatings such as polyethylene (PE) or aluminum.

After the coating system is usually a printing of the perforated and coated cardboard roll. For this purpose, the roll is mounted in the unwinding device of the printing press usually provided for this purpose and - to support a continuous production process - train impact to train impact or overlapping attached to the previous tail edge.

Following an optional perforation, the implementation of longitudinal score lines, cross and diagonal score lines, longitudinal cuts and cross sections is frequently performed. These production steps are carried out in particular at least partially in a punch. For this purpose, rolled-up web goods are then hooked into a unwinding device with the processing station present after the coating installation and printing machine, and the web is fed to the punch. As before, in front of the printing press, in order to support a clocked or continuous production process, the roll ends are also attached or glued to the web at the web end or overlapping at the previous web end edge. This can be supported by a web memory such that in a continuous manufacturing process with up to 500 meters web speed per minute roll change is done on the fly.

After the initially and as described above perforated and / or perforated and printed, coated and cut to pieces packaging material can be further processed into a finished packaging container solution takes place the often required intermediate storage of the usually stacked blanks on pallets.

This exemplified manufacturing process or the sequence of steps of the individual process steps is oriented to the process, first to manufacture the rolled Rohkartonbahn to a packaging material, then further processed in blanks and in the course in coats. The sequence described can vary in its machining sequences, so that the machines required for the production are different in their arrangement, tool combination and / or their basic structure.

One possible variation is the roll-shell production process printing on cardboard with partial weakening of the packaging material and / or over-coated hole or perforation in the printing press. Here, the cardboard roll is printed and at the end of the printing machine the perforation or perforation and the creasing lines with optional embossing and register controls are tolerated position and position exactly to the printed image produced. The printed board web is coated in the next manufacturing step with one or more plastic and / or aluminum layers.

In the next production step, the printed and coated roll web product is cut with several sheet webs above the roller conveyor width in the slitter to several single rolls, each with a curved path.

By a different variation of the processing and production sequence, the roll-sheet-sheath production process pressure on a plastic coating with partial packaging material weakenings or hole can be realized.

After at least one coating step of the paperboard base roll, the sheet webs are cut by respective longitudinal cuts of the coated web. Subsequently, the sheets are printed and separated into blanks by cross section. Holes can be implemented in parallel with the singulation. A downstream longitudinal seam processing and longitudinal seam sealing of the blanks results in coats.

If one modifies the production step sequence in the sense of a roll-roll production process pressure on cardboard with partial weakening of packaging material and / or hole insertion in the filling machine is again starting from the base cardboard present as web on rolls first printed or printed and grooved, then with at least one coating material and at least one-sided coated. The sheet webs are cut into sections by respective longitudinal cuts of the coated web and with a parallel or subsequent cross-section. Subsequent longitudinal seam processing and longitudinal seam sealing of the blanks results in sheaths. Holes and other partial packaging weakenings are realized as a jacket on the packaging solution. This step can also be done in the filling machine.

If packaging solutions are produced in the form of folding shafts and / or corrugated board materials, partially or completely modified production steps are required, which deviate from the explanations given above:

• Production of corrugated sheets:
  • - Two to three cardboard rolls are processed in one machine and glued together.
  • - A roll is first corrugated on a tool-carrying machine, characterized in that the corrugated board characteristic waveforms are impressed by heat and water in conjunction with pressing operations.
  • The corrugated web is then glued with a smooth web (printed or unprinted) at the bottom and / or top, thus forming a sandwiched material mold.
  • - This compound can not be rolled up, because then the waves would be damaged.
  • - The web goods are therefore cut into large sheets and the sheets are stacked about 2m high.
  • - This stack is now stored for 1-2 days so that the moisture can escape.
• Production of folding carton sheets:
  • - A cardboard roll is cut into sheets in a sheeter.
  • - The sheets are stacked on pallets about 2m high and so usually sent for further processing
• Further processing by printing on folding carton sheets and corrugated cardboard sheets:
  • - The sheet stacks are fed to a sheet-fed press.
  • - The sheetfed press takes a bow and pulls it through various printing units.
  • - The applied colors are dried by different systems.
  • - Optionally a paint coat is used up.
  • - Optionally, lines, cuts, holes, embossings, perforations are introduced in the paint station.

In all known or previously described production step sequences, it is necessary to transport either intermediate step products or end products of the respective manufacturing process in the form of blanks, store and / or handle. It may also be necessary to separate the blanks for or subsequent manufacturing steps.

For this purpose, usually the blanks are punched out and isolated directly in or behind the punching tool, which can be rotational or stroke-based. Then the blanks are stacked in packages and placed on pallets with intermediate layers or packed in outer cartons. As an alternative to packaging or pallet stacking, the blanks can be transported for further processing, in particular on conveyor belts located downstream of the rotary punches.

1. a. In der Stanze werden aus Bögen ein oder mehrere rechteckige oder vieleckige Zuschnitte gerillt und unter anderem an den Zuschnitträndern ausgestanzt,
2. b. die nicht benötigten Flächen zwischen den Zuschnitten und am Bogenende werden ausgebrochen,
3. c. im nächsten Fertigungsschritt werden die restlichen nicht benötigten Flächen am Bogenanfang und Bogenseite in Längsrichtung herausgezogen und
4. d. gleichzeitig werden die Zuschnitte durch einen Rahmen mit der gleichen Geometrie wie der Zuschnitt nach unten gedrückt und die Verbindungsbrücken werden getrennt und die Zuschnitte etwas auseinandergedrückt zur besseren Stapelbildung, schließlich werden
5. e. die Zuschnitte als jeweils separate Zuschnittstapel, das heißt Stapelungen einer Vielzahl der jeweils vereinzelten Zuschnitte auf Paletten quasi als Säulen gestapelt und sind ohne Verbindungsstellen zu den benachbarten Zuschnittstapeln. Es können hierbei ein oder mehrere Zwischenlagen als Stabilisierung der Stapel eingelegt sein.

For example, the following process steps can be realized:

1. a. In the punch, one or more rectangular or polygonal blanks are grooved from sheets and punched out, inter alia, at the cut edges,
2. b. the unnecessary surfaces between the blanks and at the end of the sheet are broken,
3. c. in the next manufacturing step, the remaining unneeded surfaces are pulled out at the beginning of the sheet and bow side in the longitudinal direction and
4. d. at the same time, the blanks are pushed down by a frame of the same geometry as the blank, and the connecting bridges are separated and the blanks are slightly pushed apart for better stacking
5. e. the blanks as each separate blank stacks, that is stacking a variety of each isolated blanks on pallets quasi stacked as columns and are without connection points to the adjacent blank stacks. One or more intermediate layers may be inserted here as a stabilization of the stacks.

1. i. In der Stanze beziehungsweise Rotationstanze werden aus einer Packstoffbahn ein oder mehrere rechteckige oder vieleckigen Zuschnitte ausgestanzt und die nicht notwendige Zwischenschnitte und Randschnitte werden entfernt,
2. ii. die Zuschnitte werden zuerst in Paketen gestapelt und auf Paletten gelagert oder direkt in Umkartons verpackt.

Another possibility for the realization of blank separation is possible in that, directly behind the punch, preferably rotary punch, several sheets are mechanically broken up in packages or separated by hand:

1. i. In the punch or rotary punch one or more rectangular or polygonal blanks are punched out of a packaging material web and the unnecessary intermediate cuts and edge cuts are removed,
2. ii. The blanks are first stacked in packages and stored on pallets or packed directly in cartons.

The blank separation from a sheet or a web and the individual blanks or blank stacks present therewith have a large number of considerable disadvantages in terms of handling, transport and storage or intermediate storage.

Blank stacks formed from a variety of blanks can easily slip during transport and in particular acting on the stack shear forces.

In practice, it is always necessary to align the blank stacks vertically prior to further processing or processing, in order to support the removal of the blanks from the stack, for example by deduction in a defined position. Depending on the further processing step and in particular the feeding of blanks in a preferably automatically operating Faltschachtelklebemaschine (also called AFK - Automatic Faltschachtelklebemaschine) can be done manually in an individual case to ensure the orientation and positioning of the blanks in the AFK upstream depositor.

With storage options, it is disadvantageous that pallets with blank stacks can only be stacked to a very limited extent. Another disadvantage is the limited stacking height of the blanks and the possibly required intermediate layers for stabilizing the stack.

It is an object of the invention to develop a device for the transport, handling and storage of manufacturing intermediates or blanks in or after a manufacturing process for the packaging material or packaging material production and to reduce existing disadvantages in the known manufacturing processes and process steps at least partially.

The teaching according to the invention recognizes that the handling, storage or intermediate storage and / or transport can be positively influenced by at least regional structural integrity of the blanks within the sheets and / or the clever sequence of separating blanks from the sheets. Depending on the exemplary embodiment of the invention, further advantages with regard to economic efficiency, logistics, production devices and waste reduction can be added.

According to the invention, it is provided to supplement the process steps in the primary context with the blank definition and blank separation by a production step for the production of blank sheets and / or to shift the separation of blanks from the sheets into a range of the production steps of the packaging material or packaging solution or coats based on packaging material or to locate.

The invention proposes blank sheets such that at least one or a plurality of blanks comprised of a sheet at least in some areas have a structural integrity. Preferably, all blanks of a sheet can stand with this in at least partially structural integrity to the sheet. Preferably, it is contemplated that the blank sheets are the result of the punching process, that is, the blank sheets are present after the rotary or linear working punch.

In order to realize the at least regional structural integrity, the invention proposes that the blanks are not completely cut out or punched within the sheet, but are connected to at least one contact point with the sheet material and / or an adjacent blank. Preferably, these contact points may be formed by webs, bridges, perforations or the like. It is envisaged to limit these contact points to a length of a few millimeters, preferably about 1 mm.

Contact points can be provided in the intermediate section, that is in the separation areas between blanks of the sheet and / or in edge section, that is in the separation areas.

Based on the structural integrity of the blank sheets proposed according to the invention, special properties and a number of advantages and / or at least the reduction of at least one of the disadvantages of the prior art result:

The blank sheets can be stacked on pallets and are significantly more stable in storage compared to blank stacks, with the resulting advantages of reducing slippage and increasing the possible stack height. Due to the improved positional stability, it is often possible to dispense with position-stabilizing measures such as, for example, intermediate layers. Furthermore, several pallets can be stacked with blank sheets.

The blank sheets are fed to the further processing, for example, a further manufacturing station in the context of the packaging material manufacturing process or training to coat. Alternatively, the blank sheets may serve as feed to a decentralized AFK or suitable apparatus upstream of a filling machine. In all further processing variants, it is provided to supply the blank sheets on pallets and to effect a separation of the blanks, ie the singling of the blanks from the blank sheets, only immediately before further processing. The then separated blanks can be separated and fed individually or as a package of further processing, palletized or packaged. The blanks separated from the blank sheets support various handling options such as robots, manual, pneumatic or other mechanical gripping devices.

In order to realize the blank separation from the blank sheets, the invention further proposes a blank-sheet separation machine. The blank-sheet separation machine separates the blanks by dissolving the structural integrity at the contact points by preferably inclined rollers and / or rollers with mutually different rotational speeds. For this purpose, the webs, bridges, perforations or similarly formed contact points are mechanically overloaded by longitudinal and / or transverse forces with the result of local structural failure. Alternatively, the rollers may be at least partially and / or partially formed with cutting edges to separate the webs, bridges, perforations or similarly formed contact points. The blanks separated from the blank sheets in this way can be further processed directly or transported, stored or handled in various ways.

The teaching according to the invention offers a number of advantages and / or is suitable for at least partially reducing the disadvantages of the prior art:

• • The risk of slipping of stacked blank sheets during transport is reduced as a result of the considerable areal extent,
• The need for a preferably vertical alignment of stacked blank sheets, for example before further processing and / or separation of the blank sheets, is reduced as a result of the improved positional stability,
• • Also, the increased positional stability of the blank sheets offers the at least optional possibility of at least partially dispensing with the intermediate layers which are usually required for blank stacks - so not only are liner materials saved, but also any necessary handling devices and / or handling steps,
• • as a result of the increased position stability, pallets with stacked blank sheets can be stacked better and, depending on the product, also stacked several times, thus improving the storage possibility and reducing the necessary storage space,
• The blank sheets according to the invention support the automatic feed to one or more further processing machines as a result of the increased handling suitability, so that the saving from the current, manual loading of blanks in further processing devices and the associated physical loads for the operating staff are reduced;
• The blank sheets may be designed in such a way that there is no intermediate cut in the middle area before the blanks are cut in the blank-sheet separation machine - thus the tools required for this in the rotary or linear punch are not necessary and material savings can be realized .
• • The blank sheets can be linearly guided with higher accuracy than blanks along a travel path, so that transport errors due to tilting are reduced and machine downtime is minimized and / or
• • higher transport speeds, shorter set-up times and less damage to the blanking edges in the punch can be achieved because no more blank separation is necessary and / or the knockout frame (waste material between the blanks) is omitted in the punch,
• • the depalletization of blank sheets is supported by automated handling devices,
• • the automatic feed or dislocation and feeding into the depositor of the AFK is considerably simplified,
• • manual de-palletizing and blank stack feeding in the AFK realized in the state of the art can now be automated for all blank forms and AFK machine speeds without personnel,
• • Individual blanks can be aligned vertically even when stacked, making them easier to sing before the next processing step.

1 and 2 each form sheets with blanks according to the prior art. 1 is the result of a punching process and singulation process in which sheet material between the blanks and the cut edges are punched out so that the blanks are no longer connected to each other and are present in isolated form. 2 is the result of a punching process in the sheet material along the respective outer cut margins (edge or outer cut) and partially punched out on the common blank edge boundaries (intermediate or central section), so that the blanks are connected to common webs.

3a shows a first exemplary example of the blank sheet according to the invention ( 100 ) with blanks ( 110 ) with center area ( 140 ), with contact points ( 120 ), for example in the form of perforations ( 120 ) and without boundary ( 130 ).

3b illustrates a first exemplary example of the blank sheet according to the invention ( 100 ) with blanks after a punching process without midrange ( 140 ) and with boundary ( 130 ).

3c comprises a first exemplary example of the blank sheet according to the invention ( 100 ) with blanks after a punching process and breaking process without intermediate cut and outside cut.

The at least partially structural integrity of the blank sheet ( 100 ) or blanks ( 110 ) within the arc is achieved by not completely cut out or punched out contours of the blanks ( 110 ) such that at least one contact point ( 120 ) to the sheet material and / or an adjacent blank ( 110 ) a connection remains. Preferably, these contact points ( 120 ) may be formed by webs, bridges, perforations or the like. It is envisaged to limit these contact points to a length of a few millimeters, preferably about 1 mm. Contact points can be provided in the intermediate section, that is in the separation areas between blanks of the sheet and / or in the edge section.

As a result of the blank-sheet separation machine ( 1 ) is compared to the prior art modified and optimized machining process possible in that the processing step breakup of the blanks 6a + 6b as well as a possible printing process will be relocated at a later date. So far, a well-known sequence is roll, sheet cutting, transport, sheetfed printing, transport, sheet punching, blank breakup, transport, manual loading in AFK. A sequence according to the invention is: roll, sheet cutting, transport, (sheet-fed printing), transport, sheet punching, transport, (sheet-fed printing), blank break-up, automatic loading in AFK.

4c schematically illustrates the functional sequence of the processing steps within the blank-sheet separation machine ( 1 ). The functional steps are based on a blank sheet ( 100 ) in a first separation processing step in a first separation direction and a second separation processing step in a second separation direction with the result that separate or individualized blanks ( 110 ) are present.

5 exemplifies the schematic construction side view of the blank-sheet separation machine ( 1 ) with their possible component components from the realization of the processing steps are required to the blanks sheet ( 100 ) in isolated blanks ( 110 ) and to palletize. The blank sheet separation machine ( 1 ) can use one or more pallet magazines ( 2 ) and Bogenvereinzeler ( 3 ) and optionally a printing device ( 5 ) of the blank sheets ( 100 ) upstream. After separation of the blanks ( 110 ) within the blank sheet separation machine ( 1 ) by the process preferably comprising two processing steps in the form of a separation or separation in a first sheet plane and a second sheet plane, an optional device for printing on blanks ( 12 ), the blank alignment ( 7 ), Stacking ( 8th ), Batch separation ( 9 ), an optional stack rotation ( 10 ) as well as the transport ( 11 ) be provided for further processing or palletizing. To ensure reliable handling of the blanks ( 100 ) and / or the partially isolated blanks ( 110 ) within the blank sheet separation machine ( 1 ) is intended to support the separation or cutting apart ( 6a . 6b ) in a first direction along the sheet travel direction and in a second direction transverse to the direction of travel of the sheet material within the blank-sheet separation machine ( 1 ).
