Definitions

  • the invention relates to a method and a device for producing a packaging unit, according to which individual products usually circumferentially mutually displaceable products are combined to form a product formation and fixed against each other by means of a shrink wrap.
  • the product formation usually consists of a plurality of bottles or cans lined up next to one another.
  • the bottles or cans are generally arranged both in longitudinal direction and transverse direction in rows to each other in order to simplify their numerical handling, as described for example in the generic DE 10 2006 036 590 A1.
  • a supplementary band is required to encompass, which drives the effort again in the air.
  • pads or trays have prevailed, on which the products are placed before wrapping in the shrink film. Since the pads or trays naturally have to support or absorb the entire product formation, relatively high material consumption and, consequently, high packaging costs are to be expected. This is where the invention starts.
  • the invention is based on the technical problem to provide a method and an apparatus for producing a packaging unit, with their Help packaging succeeds particularly cost-effective and at the same time functionally reliable.
  • the products are still discharged from a product stream and combined to form the product formation.
  • at least one or more separating elements are introduced between the products.
  • the expansion and attachment of the respective separating element is designed so that the product formation essentially retains its predetermined shape stability.
  • the size or placement of the partition or elements between the products must be designed and installed between the products in such a way as to maintain the dimensional stability of the formed product formation. This also applies if the product formation, for example, during its transport into a shrink tunnel or another shrinking unit, is usually exposed to laterally attacking forces which would displace the products without release agent and dissolve the product formation.
  • the separating element used is one whose surface friction or surface friction exceeds that of the products. In most cases, the individual and usually rotationally symmetrical products abut one another on the circumference. Then it is sufficient if the respective separating element is equipped with a surface friction or a surface friction coefficient which exceeds the surface friction coefficient of the associated lateral surfaces of the products. This ensures that - A -
  • the separating element can fulfill its original function, namely to "hold” the products on both sides as it were.
  • the separating element is introduced from above the product formation into one or more intermediate spaces between the products. That depends on the desired product formation. If, for example, a rectangular arrangement of the regularly cylindrical products (for example, cans) is to be retained as a product formation, then it is recommended that dividing elements are introduced into the intermediate spaces between the respective longitudinal rows (or transverse rows). This ensures that the products in the described product formation with products arranged in rows both in the transverse and in the longitudinal direction maintain this shape. Because the separating elements located in each case in the longitudinal gaps prevent the products from taking or taking the described nesting arrangement. The same applies if the separating elements at least partially fill the transverse gaps.
  • the separating element is usually introduced from above the product formation in the one or more intermediate spaces between the products, it has proven useful to work at this point with a feed device for the respective separating element.
  • This feeding device can be an often-existing side-feed device.
  • Such supplement feeders are described, for example, in DE 10 2004 030 244 B3 and generally serve to introduce packaging inserts or so-called leaflets between the products in the packaging unit.
  • these feeding devices or insert feeding devices which are already present regularly, are now used for a further purpose, namely to introduce the one or more separating elements into the intermediate spaces.
  • the device according to the invention can be realized in a particularly cost-effective manner, because ultimately only an additional supply of the separating elements to the feeding device, which usually already exists, has to be provided. It has proven useful if the separating elements are designed as separating strips.
  • the strip width of these separating strips is adapted to the product height and corresponds to this substantially or only slightly below the product height. Usually the stripe width of each

  • the separating element can also consist of individual strips which are joined to one another.
  • separator is made of paper, cardboard or the like cellulose products.
  • separators can not only produce cost-effective, but are also easily recyclable, so uncritical in terms of their disposal.
  • the invention also relates to an apparatus for producing a packaging unit, as described in claim 5 with the subsequent subclaims. Furthermore, the invention extends to a packaging unit according to claims 13 ff. Which has been advantageously prepared by the described method, and in most cases by resorting to the device for producing the relevant packaging unit.

  • a packaging unit which consists of individual mostly circumferentially mutually displaceable products 1 and a shrink wrap 2, which summarizes the individual products 1 or fixed against each other.
  • the products 1 form a product formation 3, as shown by way of example in FIGS. 1 and 2.
  • This product formation 3 is characterized in that the products 1 are arranged both in the longitudinal and in the transverse direction in rows without offset from each other.
  • these are rotationally symmetrical products 1, which in the exemplary embodiment are of cylindrical design, in the present case beverage cans.
  • this is not mandatory, because, among other things, drinks bottles and, of course, other cans (soup cans, animal feed cans etc.) can be treated comparably.
  • dividing elements 4 are introduced between the products 1 in the exemplary embodiment 2 before the shrink-wrap 2 is applied.
  • the products 1 are discharged from a transport stream and combined to form the product formation 3 shown.
  • separation device and formation device may provide a not explicitly shown separation device and formation device, which does not matter here.
  • the individual products 1 are fixed in the product formation 3 against each other, by inserting between the products 1 the already mentioned separating element 4 or the plurality of separating elements 4.
  • the design and placement of the respective separating elements 4 is chosen so that the product formation 3 essentially maintains its dimensional stability given by way of example in FIG. 2 and in FIG. 1, also during the subsequent application of the shrink wrap 2 and beyond. That is, in the example case, that the products 1 are also arranged during or after application of the shrink wrap 2 in rows and not with offset ("nesting").
  • the invention uses two separating elements 4 in the form of separating strips, which are introduced into respective longitudinal intermediate spaces 5 between individual longitudinal rows of the products 1. Since the separating elements 4 seen from their surface friction ago equipped with higher heatreibango than the products 1 on their surface, the products 1 are as it were fixed by the separating elements 4 and can not slip or slip against the separating elements 4.
  • the respective separating element 4 has a length of the separating strip realized at this point, which substantially corresponds to the length of the longitudinal intermediate space 5 in the example case or which slightly exceeds this length. Furthermore, the separating element 4 or the separating strip realized at this point has a separating strip width or strip width B, which, as shown in FIG. 3, corresponds approximately to a product height H or falls slightly below it. In any case, the strip width B is in any case greater than half the product height H.
  • the separating element 4 is essentially made of paper or cardboard, and can consequently be produced by a simple and inexpensive stamping blank.
  • an associated device has at this point a feeding device 6 which is arranged above the formed product formation 3.
  • This feed device 6 is advantageously a side feed device 6, as described by way of example in DE 10 2004 030 244 B3. That is to say, according to the invention, this supplemental feed device 6 can not only be used to place inserts between the individual products 1, but additionally serves to mount the separating elements 4 in the longitudinal intermediate spaces 5.
  • the shrink wrap 2 is slipped over the product formation 3 with the introduced separating elements 4, as described, for example, in DE 10 2006 036 590 A1 is explained in detail. Subsequently, the shrink wrap 2 undergoes heating as usual in a shrink tunnel, not shown, and contracts. This gives the shrink wrap 2 the necessary stability and ensures the firm hold of the products 1 to each other.
  • the separating elements 4 can also be combined into the longitudinal intermediate spaces 5 and / or the transverse interspaces 7 are introduced. This ultimately depends on the size of the product formation 3 and on the tendency of the products 1 to shift into a nesting arrangement. In any case, it is not difficult for a person skilled in the art to choose a suitable placement pattern for the one or more separating elements 4, depending on the size of the products 1 and the arrangement and size of the product formation 3.
  • the procedure will generally be such that the material consumption for the release agent 4 or the plurality of release agents 4 is made as small as possible. It is conceivable at this point, depending on the product formation 3 and size and shape of the products 1, to determine the optimization of the separating means 4 with regard to respective length, attachment and design with the aid of a computer optimization program. Here are the main benefits.
