Abstract

The invention relates to blank sheets and blank-sheet separation machine and method and manufacturing plant for the production and further processing of sheet-shaped packaging material to blanks or packaging solutions comprising blank sheets with structural integrity and their further processing by separation with a blank-sheet separation machine.

Description

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

In order to pack, portion, house and the like various goods, products, foodstuffs and other objects in need of protection, a variety of packaging solutions varying in their properties, designs and techniques are used. Arched packaging materials based on cardboard materials are used as the starting material for outer packaging, folding boxes, beverage and food carton packaging and so on.

When packaging any substances, consumables, powdery and lumpy substances or elements, folding boxes, wrappings or corrugated cardboard-based cardboard packaging have proven their worth. In addition to the wrapping of the material to be packaged, frequently asked requirements for packaging solutions based on sheet-like packaging materials include, for example, the reduction of external environmental influences on the goods to be packaged, dimensional stability to support stacking processes and handling through inherent stability. Packaging solutions of this type can be in direct contact with liquid, solid or flowable food as well as in the context of packaging solutions that have no direct contact with the goods to be packaged. Various applications are possible: packaging goods, food and so on in the household and / or industrial sector, for representative purposes such as sales boxes and the like.

Folding boxes, wrappings or corrugated cardboard-based cardboard packaging can be formed based on various materials and / or configurations such as, for example, non-coated sheet-shaped corrugated cardboard, printed variants, in one-sided coated, laminated and / or lacquered form. Furthermore, sheet-like cardboards are conceivable on both sides with one coating, on both sides with several coatings such as polyethylene (PE), polypropylene (PP) and / or aluminum (AL).

The above-mentioned material bases of the folding boxes, wrappings or corrugated cardboard packaging can be combined with features such as creasing lines for easier folding later, opening aids such as perforations for tearing open, openings and / or recesses to see the packaged product or recesses that 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, these can be additive or alternatively

• one or more holes with or without a continuous PE and / or PE / AL layer,
• - perforations in the carton in certain areas with at least partial or continuous PE and / or PE / AL layers,
• - One or more holes in the box with or without a 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 foods 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 and at least temporarily picking up the product to be packaged, storing it and releasing it when necessary. If the flowable or pourable products to be packaged are food in a broader sense, there may be additional requirements for the packaging solution. These include, in particular, protective functions that at least temporarily store the food in such a way that the food assumes or maintains the properties and conditions required for consumption.

An important protective function in this context is the reliable keeping away from mostly external influences on the packaged food. Protection from harmful small and very small organisms such as germs, spores, unicellular organisms and so on is very important for the shelf life, i.e. the maintenance of the food biological properties at the time of packaging. When germs come into contact with the respective food, biological processes are triggered, which spoil the food and thus make it inedible.

Another important protective function with regard to exposure to light and in particular its formation in different electromagnetic wave spectra may be required depending on the food to be packaged. light effects can, for example, lead to the destruction of vitamins and other components sensitive to infrared or ultraviolet light, so that the quality and nutritional content of foods are reduced or deteriorated. Exposure to light can also cause unsightly and unsavory discoloration.

If cardboard-based packaging solutions are used for flowable or pourable products and especially foodstuffs, measures must be taken to implement the required protective functions.

Cardboard as the primary material for cardboard-based packaging solutions is a base material made from cellulose, waste paper and / or sanded wood from various types of wood, which does not support the above-mentioned protective functions, either directly or inadequately.

In order to implement at least one of the protective functions in cardboard-based packaging solutions and / or to produce the property of hermetic tightness which is important for liquid or flowable products or foods, multilayer so-called packaging materials are created for such packaging solutions. With these packaging materials, the cardboard serves as the primary material practically as a carrier and base material for realizing the mechanically required properties and / or structural integrity. The carton 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 the effect of light can be aluminum. Aluminum in various forms, for example as a sheet or sheet, as vapor-deposited particles or dissolved in a suspension, can prevent the effect of light if the layer thickness is sufficient.

Coating materials for realizing, for example, a hermetic packaging tightness can be formed from various plastics such as polyethylene (PE), ethylene-vinyl alcohol copolymer (EVOH) or also polypropylene (PP) and can have barrier and or adhesion promoter properties in different forms. Additively or alternatively, plastic-based coating materials can give the cardboard-based packaging solution or the packaging materials further functional properties such as, for example, good printability, surface properties, surface properties and the like.

The mechanical properties of cardboard materials depend, among other things, on the base material, the type of wood used, the fiber orientation, the respective manufacturing steps, the additives added, the material density or its grammage and the material thickness and, due to fiber types, density and their orientation, can also be local in the Material vary with the result that an anisotropic base material is present at least in some areas and depending on the direction.

In addition to the aforementioned tasks, properties and requirements for packaging solutions for various goods, products, food and other items requiring protection, it may be necessary to open the packaging solution and / or reclose the packaging when only partially removing products. For this purpose, different variants are used which correspond to the basic idea of deliberately and partially limiting or modifying the mechanical properties and / or the structural integrity of the strength-determining base material cardboard in a manner that is suitable for opening and, if necessary, for (re) closing.

Often the opening or closing support modification consists in a partial weakening of the strength properties and / or removal of a partial surface element of the base cardboard.

A first variant can consist, for example, of removing a surface piece, usually in the form of a circular hole, from the base board before coating it. The required coating materials are then applied over the entire surface, that is to say over the cardboard and the removed surface area. In this way, the packaging material is partially modified to support opening and / or closing. This modification is particularly advantageous when using opening aids, closures and, in particular, twist locks or drinking straws, which interact with the partial modification.

Another variant supports the opening of the packaging solution by partially weakening the packaging material or the base carton at least partially coated to form a packaging material. For this purpose, perforations of different geometrical configurations are made in at least two layers of the packaging material or the packaging material. The perforation is preferably provided in the base carton or in the base carton and at least one coating material. In order to maintain the barrier properties with regard to exposure to light, it may be advantageous not to perforate the aluminum coating.

Packaging material is produced in a large number of manufacturing steps from a basic box, which is usually available on a roll by the meter. The dimensions of such cardboard rolls can be more than 1000 mm wide and several thousand meters long, so that a large number of cuts can be made in the longitudinal and transverse directions of the meter goods.

One speaks of a sheet or packaging material sheet if a partially or fully assembled packaging material with coatings from the piece goods is isolated in such a way that several blanks are encompassed by the preferably rectangular sheet. In the case of an isolated section of packaging material, one speaks of a cut for later packaging, which is initially further processed into a jacket by a longitudinal connection and is further processed to form a (closed, semi-open or open) package by closing at the end.

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

Various manufacturing processes and tools are used to achieve packaging weakening such as holes, cuts or perforations with different geometrical designs (e.g. so-called cuts, webs or half-cut), for example laser cutting or mechanically based perforation through rotating die plates or segments or linear motion kinematics, for example on one flatbed die cutter.

Packaging material weaknesses can be introduced at various stages of packaging material production and / or before a packaging solution is filled with a product to be protected. For this purpose, roll cutters, coating systems, printing machines, punches, longitudinal seam machines, rewinders, sheeters (ie roll sheet-cutting machines) and / or filling machines can be equipped with suitable devices.

A possible production step sequence described below by way of example can consist in firstly introducing weakenings in the form of holes in the base or raw cardboard in the form of webs on rolls.

The web-shaped cardboard starting material is fed from the raw cardboard roll in a preferably continuous unwinding process to a coating system with a rotary hole punch and one or more holes are punched next to one another and / or in the roll length in each subsequent package cut. The roll width usually corresponds to a plurality of pack heights and the roll length corresponds to the pack width.

The introduction of holes into the raw cardboard web after punching holes in the first station of a coating system 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 specified winding characteristic. This winding alignment, that is to say the respective position of the coatings on the outer or inner diameter of the roll to be wound, can take place as a function of the coating material. With regard to this criterion, a distinction is usually made between plastic coatings such as polyethylene (PE) or aluminum.

The perforated and coated cardboard roll is usually printed after the coating system. For this purpose, the roll is hooked into the unwinding device of the printing press, which is usually provided for this purpose, and - in order to support a continuous production process - is fastened web-to-web or overlapping on the previous web end edge.

Following an optional perforation, longitudinal creasing lines, cross and diagonal creasing lines, longitudinal cuts and cross sections are often implemented. These manufacturing steps are carried out, in particular, at least partially in a punch. For this purpose, rolled-up web material is hung into a roll-off device with the processing stand that is present after the coating system and printing machine, and the web is fed to the punch. As before, in front of the printing press, the roll ends are attached or glued to the butt or overlap on the previous end of the web to support a clocked or continuous production process. This can be supported by a web storage device in such a way that in a continuous production process with a web speed of up to 500 meters per minute, the roll change takes place on the fly.

After the perforated and / or perforated and / or printed, coated, and cut to size blanks, which have been perforated and / or described above, can be further processed into a finished packaging container solution the frequently required intermediate storage of the blanks, which are usually stacked, on pallets.

This exemplary manufacturing process or the sequence of steps of the individual process steps is based on the process of first manufacturing the rolled raw cardboard web into a packaging material, then further processing it into blanks and then further into jackets. The sequence of operations described can vary in its processing sequences, so that the machines, which are required for production, differ in their arrangement, tool combination and / or their basic structure.

One possible variation is the roll-jacket production process, printing on cardboard with partial weakening of the packaging material and / or over-coated hole or perforation in the printing machine. Here, the cardboard roll is printed and at the end of the printing machine the hole or perforation and the creasing lines with optional embossing and register controls are tolerance-accurate manufactured to the exact position and location of the printed image. In the next manufacturing step, the printed cardboard web is coated with one or more plastic and / or aluminum layers.

In the next production step, the printed and coated roll material is cut with several sheets over the width of the roll in the slitter into several individual rolls, each with one sheet.

Another variation of the processing and manufacturing sequence allows the roll-sheet-sheath manufacturing process to be realized on a plastic coating with partial packaging material weaknesses or holes.

After at least one coating step of the cardboard base material roll, the sheet webs are cut through respective longitudinal cuts of the coated web material. Then the sheets are printed and cut into cross-sections. Holes can be implemented parallel to the separation. Downstream longitudinal seam processing and longitudinal seam sealing of the blanks results in jackets.

If the sequence of production steps is changed in the sense of a roll-roll production process, printing on cardboard with partial weakening of the packaging material and / or perforation in the filling machine is again based on the basic cardboard in the present case as web goods 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 blanks by respective longitudinal cuts of the coated web material and with a parallel or subsequent cross section. Subsequent longitudinal seam processing and longitudinal seam sealing of the blanks results in jackets. Holes and other partial weakening of the packaging material are realized as a jacket on the packaging solution. This step can also be done in the filling machine.

If packaging solutions are manufactured in the form of folding shafts and / or corrugated cardboard materials, partially or completely changed manufacturing steps differing from the explanations given above are required:

Production of corrugated cardboard sheets:

• - Two to three cardboard rolls are processed in one machine and glued together.
• - A roll is first corrugated on a tool-carrying machine in that the waveforms characteristic of the corrugated cardboard sheets are embossed by the action of heat and water in connection with pressing processes.
• - The corrugated web is then glued to a smooth web (printed or unprinted) at the bottom and / or at the top, thus forming a sandwich material shape.
• - This composite can no longer be rolled up because the shafts would be damaged.
• - The web goods are therefore cut into large sheets and the sheets are stacked approx. 2 m high.
• - This stack is now stored for 1-2 days so that the moisture can escape.

Manufacture of folding box sheets:

• - A cardboard roll is cut into sheets in a cross cutter.
• - The sheets are stacked on pallets approx. 2m high and are usually sent for further processing

Further processing by printing on folding box sheets and corrugated cardboard sheets:

• - The sheet stacks are fed to a sheet printing machine.
• - The sheetfed press takes a sheet and pulls it through different printing units.
• - The applied colors are dried by different systems.
• - Optionally, a layer of lacquer is used up.
• - Optionally, lines, cuts, holes, embossments, perforations are made in the creasing station.
• - At the end of the printing process, the sheets are stacked again on pallets approx. 2 m high.

Further processing by punching folding box sheets and corrugated cardboard sheets:

• - The sheet stacks are fed to a sheet punching machine.
• - The sheet punching machine takes a sheet and pulls it through various punching and stripping stations.
• - Creases, cuts, holes, embossments, perforations are made.
• - Unnecessary corners, holes, intermediate surfaces are broken out. (Partly manually after punch)
• - There are individual cuts that are no longer connected. (Partly manually after punch)
• - At the end of the punching process, the blanks are stacked again on pallets approx. 2m high with paper intermediate layers to stabilize the stacking of columns.
• - The blanks without gluing are then delivered to the customer.
• - The blanks with adhesive / sealing are processed in the AFK.

Further processing by gluing blanks:

• - The blanks with gluing and shaping are processed further in an automatic folder gluer (AFK).
• - The blanks are shaped, folded and glued in the AFK and folded flat again and packed in cardboard boxes.
• - At the customer, the flat-folded blanks / jackets are set up so that half-open or closed boxes are created.

Production of coated or uncoated folding boxes in roll form:

• - The cardboard roll is printed, grooved and punched.
• - The printed or unprinted cardboard roll is coated or laminated (optionally with previously punched holes).
• - The unprinted, coated cardboard roll is printed on the coating side.
• - The coated or uncoated roll is further processed in the roll punch by introducing creases, cuts, holes, embossments, perforations.
• - Unnecessary corners, holes, intermediate surfaces are broken out. (Partly manually after the punch)
• - There are individual cuts that are no longer connected.
• - At the end of the punching process, the blanks are stacked again on pallets approx. 2 m high with paper intermediate layers to stabilize the column stacking or as blanks packages are fed directly to AFK.
• - The blanks without gluing are then delivered to the customer.
• - The blanks with adhesive / sealing are processed in the AFK.

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

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

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 implemented:

1. a. In the punch, one or more rectangular or polygonal blanks are grooved from sheets and, among other things, punched out on the blank edges,
2. b. the unnecessary areas between the blanks and at the end of the sheet are broken out,
3. c. In the next production step, the remaining unneeded areas at the beginning and side of the arch are pulled out lengthways and
4. d. at the same time the blanks are pressed down by a frame with the same geometry as the blank and the connecting bridges are separated and the blanks are pushed apart a little for better stack formation, finally
5. e. the blanks are stacked as separate stacks of blanks, that is, stacks of a large number of the individual blanks on pallets, as it were, and are without connection points to the adjacent stack of blanks. One or more intermediate layers can be inserted to stabilize the stack.

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 of realizing the cutting of individual cuts is possible in that several sheets in packages are mechanically broken up or separated by hand directly behind the punch, preferably rotary punching:

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 outer cartons.

The separation of blanks from a sheet or a web and the individual blanks or stacks of blanks that are present have a number of considerable disadvantages with regard to handling, transport and storage or intermediate storage.

Blanks of blanks formed from a large number of blanks can slip very easily during transport and in particular with transverse forces acting on the stack.

It is practically always necessary to align the stack of blanks vertically before further processing or processing in order to support the removal of the blanks from the stack, for example by pulling them off in a defined position. Depending on the further processing step and in particular the feeding of blanks into a preferably automatically working folding box gluing machine (also called AFK - automatic folding box gluing machine) it may have to be done manually in individual cases in order to ensure the orientation and positioning of the blanks in the inserts upstream of the AFK.

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

It is the object of the invention to further develop the device and method for the transport, handling and storage of intermediate production products or blanks in or after a production method for the production of packaging material or packaging material and to at least partially reduce the disadvantages existing in the known production methods and process steps.

The teaching according to the invention recognizes that handling, storage or intermediate storage and / or transport can be positively influenced by at least in some areas structural integrity of the blanks within the sheets and / or skillful sequence of the separation of blanks from the sheets. Depending on the embodiment of the invention, there may be further advantages in terms of economy, logistics, production devices and reduction in rejects.

According to the invention, it is provided that the process steps in the primary context with the cut definition and cut separation are supplemented by a production step for the production of cut sheets and / or to shift the separation of cuts from the sheets into an area of the production steps of packaging material production or packaging solution or shells based on packaging material or to locate.

The invention proposes blank arches in such a way that at least one or a plurality of blanks encompassed by an arch have structural integrity at least in some areas. All of the cuts of a sheet can preferably be at least regionally structural to the sheet with this sheet. It is preferably contemplated that the blank sheets are the result of the punching process, that is to say the blank sheets are present after the rotary or linear punch.

In order to achieve the structural integrity at least in certain areas, the invention proposes that the blanks within the arch are not completely cut out or punched out, but are connected to at least one contact point with the sheet material and / or an adjacent blank. These contact points can preferably be formed by webs, bridges, perforations or the like. It is intended to limit these contact points to a length of a few millimeters, preferably approximately 1 mm.

Contact points can be provided in the intermediate cut, that is to say in the separating areas between cuts of the sheet and / or in the marginal cut, that is to say in the separating areas.

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

The cut sheets can be stacked on pallets and are considerably more stable in position than cut stacks with the resulting advantages that slipping is reduced and the possible stack height is increased. Due to the improved position stability, measures to stabilize the position, such as intermediate layers, can often be dispensed with. Furthermore, several pallets can be stacked with cut sheets.

The cut sheets are fed to further processing, for example to a further production station in the course of the packaging material production process or the training for the jacket. Alternatively, the cut sheets can serve as feed material for a decentralized AFK or a suitable device upstream of a filling machine. In all further processing variants, it is provided to feed the cut sheets on pallets and to separate the cut pieces, that is to say to separate the cut pieces from the cut sheets, only immediately before the further processing. The individual blanks can then be separated, individually or as a package for further processing, palletized or packaged. The individual cuts from the cut sheets support various handling options such as robots, by hand, pneumatic or other mechanical gripping devices.

The invention furthermore proposes a blank-sheet separation machine for realizing the blank separation from the blank sheets. The blank-sheet separation machine separates the blanks by preferably inclined rollers and / or rollers with different rotational speeds by dissolving the structural integrity at the contact points. For this purpose, the webs, bridges, perforations or similarly designed contact points are mechanically overloaded by longitudinal and / or transverse forces, with the result of local structural failure. Alternatively, the rollers can be at least partially and / or partially formed with cutting edges in order to separate the webs, bridges, perforations or similarly designed contact points. The blanks separated from the blank sheets in this way can be further processed immediately 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 due to the considerable area extension,
• • The need for a preferably vertical alignment of stacked blank sheets, for example before further processing and / or a separation of the cut sheets is reduced due to the improved positional stability,
• • The increased positional stability of the blank sheets also offers the at least optional option to at least partially dispense with the intermediate layers that are usually required in the case of blank stacks - this not only saves intermediate layer materials, but also any necessary handling devices and / or handling steps,
• Due to the increased position stability, pallets with stacked cut sheets can be stacked better and, depending on the product, several times, so that the storage option is improved and the necessary storage space is reduced,
• The cut sheets according to the invention support the automatic feeding to one or more further processing machines due to the increased handling suitability, so that the savings from today's manual insertion of cuts in further processing devices and the associated physical stress for the operating personnel is reduced,
• • The cut sheets can be designed in such a way that there is no intermediate cut in the center area before the cuts are separated in the cut-sheet separation machine - the tools required for this in the rotary or linear punch are not necessary and material savings can be realized .
• • The cut sheets can be guided linearly with higher accuracy than cuts along a movement path, so that transport errors due to canting are reduced and machine downtimes are minimized and / or
• Higher transport speeds, shorter set-up times and less damage to the cut edges in the punch can be achieved, because there is no longer any need to separate panels and / or the stripping frame (cutting material between the cuts) is no longer required in the punch,
• The depalletizing of cut sheets is supported by automated handling devices,
• The automatic feeding or placing and feeding into the insert of the AFK is considerably simplified,
• The manual depalletizing and cutting package feed in the AFK, which has been implemented in the prior art, can now be automated for all cutting shapes and AFK machine speeds without personnel,
• • Individual blanks can already be aligned vertically in the stacked state, making them easier to separate before the next processing step.
