Method and system for inserting a good to be packaged

The invention relates to a method for enveloping goods to be packaged with the method steps (a) feeding the goods to be packaged to a wrapping unit by means of a first feed unit, (b) cutting a pack blank from a material provided, (c) feeding the pack blank the wrapping unit by means of a second feeding unit, (d) combining the goods to be packaged and the packaging blank in the wrapping unit, and (e) wrapping the goods to be packaged with the packaging blank by the wrapping unit, wherein the good to be packaged and the packaging blank in at least one section in a line and in opposite directions of the wrapping unit are supplied. Furthermore, the invention relates to a system for enveloping goods to be packaged with a receiving unit and a cutting unit for producing packaging blanks from a provided material, a wrapping unit, a first feed unit for supplying goods to be packaged to the wrapping unit and a second feed unit for Supplying the packaging blanks to the wrapping unit, wherein the first and second feed unit are arranged such that the supply of the goods and the packaging blanks in at least one section in a line and in opposite directions.

From the production of goods, in particular magazines, (advertising) brochures, or letters, and the packaging to the finished, packaged product go through both the goods to be packaged and the packaging many different stations. In this case, the production of the goods and the production of the packaging is usually locally separated from each other and this only when inserting manually or automatically united by an inserter. However, such a decentralized production of the individual packaging components leads to additional production costs, due, among other things, to

CONFIRMATION COPY port and storage costs, and longer production times, inter alia due to the transport routes, or production losses, if the good or the packaging material is not in stock and must be ordered externally.

Newer inserting systems try to take over individual production steps in the production of the goods or the packaging and thus to reduce the production times and production costs. As a rule, the production of the goods, in particular the printing, the cutting and the sorting of the blank, is taken over by a separate production unit and the goods are fed directly to the inserting machine. This good is then automatically placed by the inserter in provided packaging. A disadvantage of this type of inserter is further that the packaging must be made externally and thus incur additional transport and storage costs.

In other inserting systems, both the production of the goods and the production of the packaging are taken over by the inserting machine. In this case, a material web is printed by an external printing unit in such a way that first the complete good is printed on the material web, for example individual sheets of a letter, before a packaging blank, for example an envelope with an address field, is printed on the material web. This finished material web with several goods and packaging blanks in exchange is then added to the inserter, which cuts the material web according to the goods and the packaging blanks and then combines both. A disadvantage of this method is that the goods and the packaging blanks are always made of the same material by the common material web. Such a limitation of the materials is not desirable in many cases.

The invention is therefore an object of the invention to provide a method for enveloping to be packaged Good and such a system that allows for low production costs and production times a particularly flexible, easy and fast packaging of the goods. With regard to the method, this object is achieved according to the invention by the packaging blank comprises two side flaps, a bottom flap and a flap and by the wrapping of the goods to be packaged the additional process steps: wrapping the goods to be packaged by folding the side flaps, and wrapping the goods to be packaged Folding the bottom flap in any order, gluing the side flaps and the bottom flap, wrapping the goods to be packaged by folding the flap includes. With respect to the system, this object is achieved according to the invention by the packaging blank comprises two side flaps, a bottom flap and a flap and the wrapping unit means for folding the side flaps and the bottom flap, means for bonding the side flaps and the bottom flap and means for wrapping the goods to be packaged Folding the flap includes.

Advantageous embodiments of the invention are the subject of the dependent claims.

The invention is based on the consideration that the production costs and production times are significantly influenced by the recourse to external production facilities and thus resulting delivery times and required storage space. A reduction of these costs and production times can therefore be achieved if both the goods to be packaged and the packaging can be produced on site. A further reduction is possible, although the storage of locally produced goods or packaging can be avoided and the production and enveloping is thus possible within a plant. For a very flexible and customizable enveloping the packaging is not made before merging with the goods to be packaged but initially provided only packaging blanks. In order to avoid further work steps and the supply of packaging blanks on several feed tracks, the packaging blanks are in one piece and already completed. This means that they already include the side flaps, the bottom flap and the closure flap, and that the packaging blank is not first removed in a further step before or after the release. leadership, for example in the form of a Wrapers, must be made or completed. These packaging blanks are combined with the goods and the good then wrapped by folding the packaging blank. For a particularly simple and positionally accurate combination of goods and packaging blanks while changes in the feeding direction should be avoided consistently. For this reason, the supply of the goods and the packaging blanks done from a bird's eye view in a line and in opposite directions. By the opposite arrangement, a particularly easy accessibility to the two supply units and the upstream units for providing and / or production of the packaging blank and the goods is possible.

In order to enable the provision of the most stable and secure packaging, the side edges are folded first, then the bottom flap and only then the flap. Such a folding and gluing order makes it possible to produce standard (letter) envelopes which meet particularly stringent requirements for the stability of the packaging. By this folding sequence, the maximum space for the goods to be packaged can be provided for given packaging sizes, for example by specifications by the letter or parcel delivery service. In an alternative embodiment, it is also possible that first the bottom flap is folded and only then the side edges and the flap. In this folding, the gluing of the side edges and the bottom flap is outside. A possible contact between the adhesive material and the good can thus be excluded.

For a quick and secure enveloping of the goods, the combination of the goods to be packaged and the packaging blank is carried out in line and in the same direction relative to one another in a particularly advantageous embodiment. This allows a simple and positionally accurate storage of goods on the packaging blank and thus a simple union without relative movement of the goods and the packaging blank. As a result, continuous operation of the plant ge, by a constant supply of packaging blanks, possible without short downtime or a stop-and-go erfoderlich.

For a particularly accurate folding of the packaging blank, a folding in the direction of movement of the packaging blank is consistently avoided. In this case, the side edges are folded parallel to the direction of movement and the packaging blank positioned under the Good so that a folding of the bottom flap against the direction of movement is possible. In order to avoid a folding of the closure flap in the direction of movement of the packaging blank, in a particularly preferred embodiment, the direction of movement of the already partially enveloped material is rotated by approximately 90 °, without thereby rotating the packaging blank. Only by this rotation, a folding of the flap is made possible parallel to the direction of movement. Due to this particular guidance of the packaging blank during folding, it is possible to produce packaging and in particular envelopes in which the folding edge of the closure flap and the folded edge of the bottom flap are arranged substantially parallel to one another. As a result, size specifications, for example, by the letter or parcel delivery service can be optimally met. Depending on the customer's request, however, a different form of packaging can be produced by the angle of change of the direction of movement is selected accordingly.

For particularly diverse applications, in particular for the production of packaging and envelopes with window elements, a window element is cut into the packaging blank in a preferred embodiment during or after the blank of the packaging blank. This window element is then covered by a window film. The window film is glued to the inside of the packaging blank and covers the window element completely.

In the present system, the packaging blanks are cut directly from a material web. This means that any addresses, advertising fields or company logos on the packaging may have already been printed on the web. But this has the disadvantage that individual changes or Errors can lead to the replacement of the complete web. For a particularly flexible and cost-effective provision of printed envelopes, therefore, the cut packaging blanks and not the material web are printed in an advantageous embodiment. It is thus possible to use a single, unprinted material web for the production of the packaging. A storage of printed material webs or rejects of entire webs due to misprints or order changes can thus be avoided. In an alternative or additional advantageous embodiment, a printing of the packaging is also provided after the wrapping of the goods.

To reduce the storage costs and the required storage volume is provided in a preferred embodiment, that the good, usually this form letters, advertising flyers or leaflets are cut from a web and the blank is fed directly to the wrapping unit. As with the envelopes, it is also conceivable that the good is cut from a blank web and is printed individually after cutting by a printing unit. For a particularly positionally accurate union of the goods to be packaged and the packaging blank, the cut and collectively packaged goods are collected by means of a collecting unit and fed together to the wrapping unit in a particularly preferred embodiment. It is conceivable that the collecting unit also performs a desired folding, gluing or other connection of the collected goods.

The advantages achieved by the invention are, in particular, that a particularly simple combination of the two in the wrapping unit is made possible by the special supply of the goods and the already completely present packaging blank. Thus, both in the production of good as in the production of the packaging can be consistently dispensed with external production and thus cost-effective and with little downtime each good be packed. In addition, the materials used for the goods and the packaging can be freely and independently determined and the dimensions of the blanks adjusted individually. An embodiment of the invention will be explained in more detail with reference to a drawing. Show:

FIG. 1 is a schematic representation of the method for enveloping a product to be packaged,

FIG. 2 a schematic representation of an insertion system.

Identical parts are provided with the same reference numerals in all figures.

The schematic representation of the method of FIG. 1 comprises a first material web 1 for the packaging blanks. The material of the web 1 can be chosen arbitrarily and according to the customer's request, usually paper in different strengths or even a packaging film is used. In a first method step 2, the material web 1 is cut into packaging blanks 6 by means of a cutting unit 4. In this case, a particularly individual blank is possible, which can also be changed from packaging blank 6 to packaging blank 6 by a corresponding control of the cutting unit. Thus, a direct and optimal adaptation to the goods to be packaged 8 is possible. If the material web 1 and therefore also the packaging blank 6 are already completely printed, the packaging blank 6 is fed to the wrapping unit 12 in the next method step 10. Otherwise, the packaging blank 6 can be individually and individually printed by a printing unit 14 before being fed to the wrapping unit 12 in a method step not shown. In addition or in an alternative embodiment, however, it is also possible that an additional printing unit 62 already prints on the material web 1. This has the advantage that it can be printed over the entire later cut and thus no system-related pressure-free edges arise. By using two printing units connected in series, it is also possible to print the packaging both on the outside and on the inside. It is likewise possible for a window element 68 to be cut into the packaging blank 6 in a further method step preceding the feed to the wrapping unit, or also together with the blank of the packaging blank 6, and this is closed with a window film. This makes it possible to produce packaging, in particular envelopes, with a viewing window.

The schematic representation of the method of FIG. 1 also comprises a second material web 16 for the production of the goods 8 to be packaged. This second material web 16 is cut by a second cutting unit 18 into individual parts of the good 20. If the second material web 16 is not yet printed, one could not shown, another printing unit in a likewise not shown, further process step, the individual parts of the goods 20 are individually printed. The parts of the goods 20 are then fed to a collecting unit 24. This collecting unit 24 is able to sort the parts of the goods 20 and merge them into a good 8. In addition, it is possible by the collecting unit 24 to fold the goods 8 according to the customer's request, to glue to emboss, to connect by means of a staple or paper clip or otherwise edit. Furthermore, it is possible in the collecting unit 24 to add external inserts 64, such as, for example, credit cards, CDs or promotional items, manually or automatically to the product 8. The finished product 8 is subsequently fed to the wrapping unit 12.

For a particularly reliable and accurate positioning of the goods 8 on the associated packaging blank 6 and error-free further processing by the wrapping unit 12, the feed paths 10, 28 are arranged in a line but in opposite directions. A necessary rotation of the goods 8 in the plane of movement or the packaging blank 6 in the feed is avoided as well as an undesirable displacement of the packaging blank 6 by changes in direction in the feed. The combination of the goods 8 and the packaging blank 6, however, is performed in a line and the same direction. As a result, relative movements between the two are avoided and the good 8 can be placed accurately positioned on the packaging blank 6 in a particularly simple manner, for example by filing. Due to this special type of feed, the product 8 to be packaged lies in the wrapping unit 12 on the inside of the packaging blank 6.

In a first wrapping process 30, the side flaps 32 of the packaging blank 6 are folded parallel to the direction of movement of the packaging blank 6 and beaten around the crop 8. At the same time or in a downstream process step, the outside of the side flaps is covered with an adhesive film. In a second wrapping process 34, the bottom flap 36 is then folded against the direction of movement of the packaging blank 6, beaten around the good 8 and glued to the side flaps 32.

To avoid folding in the direction of movement, the direction of movement of the packaging blank 6 and of the material 8 located in it is rotated by about 90 °, without, however, the orientation of the packaging blank 8 changes. As a result of this change in the direction of movement relative to the orientation of the packaging blank 8, a folding 38 of the closure flap 40 parallel to the new direction of movement of the packaging blank 8 is possible. The folding edges of the closure flap 40 and the bottom flap 36 are arranged approximately parallel to one another in such a rotation of the movement direction, so that particularly symmetrical packaging can be produced. In this fold 38, the packaging is closed and the goods 8 completely wrapped. Depending on the further processing of the packaged product 42, the closure flap 40 can be glued directly to the end of the bottom flap 36 during folding. For this purpose, an adhesive film can be applied directly in the end region of the bottom flap 36 and / or on the inside of the closure flap 40 in a further process step carried out upstream or with the folding.

An embodiment of the inserter 43 is shown in FIG. 2 shown schematically. The inserting machine 43 comprises a packaging unit 44 for producing and feeding the packaging blanks 6 to form a wrapping unit 12 and a good unit 46 for producing, sorting, collecting and feeding the goods 8 also to this wrapping unit 12th

The packaging unit 44 comprises, in the order of the method steps, a receiving unit 48 for the packaging material, for example a material web or roll 1, a cutting unit 4 which cuts this packaging material into packaging blanks 6, a first and a second printing unit 14, 62 which holds the packaging blanks 6 printed on demand and a feed unit 50, which supplies the packaging blanks 6 of the wrapping unit 12. In addition, the packaging unit may include a unit for cutting and applying window elements 68 to the packaging blank.

Also, the good unit 46 comprises a separate receiving unit 52 for a material web or roll 16. In a downstream, second cutting unit 18 parts of the material 20 are cut from the web 16. These can optionally be printed individually by a further, not shown printing unit. Downstream of the cutting unit 18 is a collecting unit 24, in which the parts of the goods 20 can be collected, sorted and further processed. Also, an external supply of other supplements or other parts of the goods to be packaged 8 manually or automatically possible. The collected and to be packaged Good 8 is passed over its own feed unit 54 of the wrapping unit 12.

The wrapping unit 12 is designed to safely and permanently enclose the goods to be packaged 8 by the supplied packaging blank 6 in several folding and gluing rides. For the simplest and most accurate folding of the closure flap, the wrapping unit 12 is formed L-shaped, wherein the folding of the side flap and the bottom flaps a first portion 56 and the folding of the flap in a second portion 58 is made to the first portion 56 to twisted about 90 °. The wrapping unit according to the embodiment of FIG. 2 also includes a separate printing unit 60, in which the finished end product 42 can be printed again or first time when needed. The feed units 50, 54 of the packaging blank 6 and of the goods 8 are arranged in such a way that the feed - seen from a bird's eye view - is in a line and in opposite directions. In this case, the packaging blank 6 is brought to this on a lower level, below the wrapping unit 12, while the crop 8 is fed to the wrapping unit at a higher level. When feeding the packaging blank 6 to the wrapping unit 12, it is moved along a curved or circular segment. This corresponds to a roller-like rotation of the packaging blank 6, which does not have to be realized via a roller element, but also by a corresponding arrangement of conveyor belts or similar conveying elements is possible. As a result of this type of rotation of the packaging blank 6, its orientation relative to the direction of movement is not changed, as a result of which displacement during movement and thus later inaccurate positioning can be avoided.

By such a supply of the goods 8 and the packaging blank 6, it is also possible that the goods can be stored accurately positioned on the packaging blank 6. As a result, a complete enclosure of the goods 8 is made possible. It is thus possible to dispense with prefabricated and externally produced packaging.
