Definitions

  • the present invention relates to a method for producing strapping bundles with the features of independent method claim and such a strapping bundle with the features of independent claim 10.
  • the invention also relates to a strapping machine with the features of independent claim 8 for producing strapping bundles.
  • While the individual articles or containers in the case of adhesive containers are joined directly to one another with adhesive by means of adhesive connections, the containers in the case of strapped containers are held together by means of at least one strapping strip stretched horizontally around the container.
  • the bands can be formed by paper bands, which are to be made relatively wide for reasons of stability. Straps made of plastic are generally more stable and can therefore normally be pretensioned more than those made of paper that the containers cannot be deformed or even damaged due to excessive prestressing. Precise adjustment of the pre-tension can also help to prevent a strapped container equipped with this from becoming too unstable during handling due to insufficient pre-tension and the containers being able to slip out of the bundle.
  • plastic straps in the manufacture of strapped bundles are not entirely uncontroversial, not least for ecological reasons. Nevertheless, due to their material properties, such plastic straps can provide a favorable relationship in the conflict of objectives between the lowest possible use of material and the highest possible mechanical strength, especially since the plastic straps can be imprinted with a defined elasticity, which makes it easier to equip the strapping straps with the required pretension. In this way, on the one hand, the risk of deformation or even damage to containers that are held together due to excessive prestressing can be countered. On the other hand, sufficient prestressing can effectively prevent the containers from falling apart and undesired dissolution of the mechanical bundle assembly.
  • the primary aim of the invention is to provide a strapping package that is simple and inexpensive to produce and has sufficient mechanical stability, as well as a method for the simple and inexpensive production of such mechanically stable strapping packages.
  • the present invention proposes a method for producing strapped bundles with the features of the independent method claim, in which at least three articles are put together and joined together and held together by strapping.
  • three or more items of the same type i.e. items of the same size and/or weight and in particular the same shape, can be put together and joined to form a strapped bundle, although this is not a mandatory prerequisite for achieving the stated goal and for implementing the method according to the invention.
  • the assembled articles it is necessary for the assembled articles to have cylindrical or approximately cylindrical lateral surface sections, at least in the area surrounded by the strapping and/or in areas in which the adjacent articles touch, so that they can enable rolling movements explained in more detail in connection with the transformation of the article composition.
  • Such articles with lateral surface sections that are at least partially cylindrical or approximately cylindrical are found, for example, in bottles, beverage containers or cans made of plastic, metal or mineral glass, so that the articles assembled using the method, which form the strapped container produced using the method, are present in the present context especially through such Liquid or beverage containers can be formed, ie by PET bottles, mineral glass bottles or beverage cans made of aluminum sheet or tinplate, optionally also made of plastic or composite materials.
  • All of these article or container shapes mentioned generally have hollow-cylindrical contours, at least over larger sections of their lateral surfaces, so that the lateral surfaces of the articles or containers that are joined in line contact can roll on one another in the manner described in more detail below without this rolling movement being counteracted by any undesired resistance which would certainly be the case with non-cylindrical article or container contours.
  • the strapping is formed by at least one prefabricated, closed strapping band, the length of which corresponds approximately to a total circumference of the article combination located in a diagonal arrangement or spherical packing when the at least one strapping is attached.
  • At least three articles, in particular articles or containers of the same type, are first assembled and grouped, the articles being assembled and grouped in a diagonal arrangement so that the articles touch on their lateral surfaces, in particular in line contact.
  • the at least three articles of the grouped diagonal arrangement are slipped over the strapping loosely or almost without tension, usually in a direction parallel to a longitudinal direction of the articles, i.e. in a direction from top to bottom, since the articles usually with their bottom surfaces stand on a base or supporting surface, so that the strapping can be more easily brought from above over the article tops and slipped over the article composition.
  • the item assembly is in a diagonal arrangement, which means the tightest possible packing of the items or containers.
  • the three or more articles or containers together in such a way that all horizontal lines within a plane drawn between longitudinal central axes passing vertically through the articles or containers form isosceles triangles between their intersections, respectively. It is therefore not possible to pack the items even more densely by assembling the articles in a different way than that mentioned.
  • the items in a diagonal arrangement which are surrounded by the strapping in the horizontal direction, are transferred into a rectangular arrangement or, in the special case of a 3x1 bundle, into a linear arrangement, against the resistance of the elastically yielding and tensioning strapping, whereby the Strapping is stretched and the closed strapping is imprinted with a defined strap tension that mechanically stabilizes the strapping.
  • the transfer to the linear formation takes place, for example, by shifting the respective middle articles or containers in each row of three, which increases the outer circumference of the bundle in a defined manner, usually in the order of about a two to five percent change in length.
  • An essential advantage of the method according to the invention is that a resultant prestressing force of the strapping band of the finished strapping bundle is generated by an increase in the overall circumference of the article combination forming the strapping bundle when it is transferred into the rectangular arrangement.
  • the strapping is stretched in the same way, which generates elastic restoring forces and ultimately the desired holding forces in the bundle.
  • part of the prestressing force of the strapping can also be generated by deformation and/or compression of the articles in the casing areas on which the strapping is guided, provided that the articles are at least slightly deformable in the casing areas surrounded by the strapping and have elastic restoring forces .
  • mineral glass bottles on the other hand, this effect is completely absent, since the shell sides of the bottles are completely inelastic.
  • the strapping is elastically stretchable in the longitudinal direction and since the containers or articles can also be at least slightly elastically deformable, the strapping is pretensioned by a defined or definable amount during and through the transfer of the article assembly into the rectangular arrangement, which results in the desired mechanical strength and the can provide mechanical cohesion of the article composition in the finished strapped bundle. It should be expressly mentioned at this point that the effects mentioned - the pre-tension and stretching of the strapping and the elastic deformation of the article's outer surface - can certainly be superimposed to form an overall effect, which in terms of the achievable values usually ensures a sufficiently high pre-tensioning force and sufficient high holding forces in the bundle association will have to be determined through tests.
  • different container sizes can be processed and produced, whereby naturally at least three preferably similar articles, containers or bottles are required, which can initially be arranged in a triangular bond, so that they are surrounded by a prefabricated strapping band and then transferred into a stretched row arrangement which also corresponds to a rectangular arrangement within the meaning of the present definitions since the articles are no longer in their original triangular arrangement but are aligned in a straight line.
  • the method can additionally provide that special strapping strips are used, which are each equipped with a non-slip surface on their inner sides facing the article jacket sides, whereby the articles are held in the rectangular arrangement by generating a defined frictional force between the article or bottle lateral surfaces and the strapping.
  • This makes it easier to maintain a stable pack formation, with a non-slip counter surface also being provided on the articles, if necessary, so that there is a material pairing between the insides of the straps and the surface areas of the article jacket sides covered by them, which can counteract the straps slipping.
  • the strap can optionally be formed by a plastic strap, a paper strap or a cardboard strap with welded and/or glued and/or clamped overlapping end sections. If such a strapping band is used, which is connected to its ends after cutting to length, e.g.
  • the strapping band is formed by an endless material without a connection point.
  • a strip material can be cut, for example, from a tube or film tube and fed continuously as individual strip sections.
  • Such an endless belt without conventional connecting or joining points can be formed, for example, by a plastic belt or by a reinforced cellulose or paper belt that has the desired elastic properties in the longitudinal direction of the belt in order to be able to ensure the desired stability of the pack.
  • the strapping can also be made of a suitable plastic material, in particular a thermoplastic material, paper, cardboard, metal, a molded fiber part or other flexible material, provided it has the desired elastic properties in the longitudinal direction of the strap so that the desired stability of the pack can be guaranteed.
  • a very advantageous addition to the method according to the invention can provide for the articles in the strapping bundle to be equipped with adhesive points or adhesive strips at least at some of their contact points where their lateral surfaces touch one another in the transferred rectangular arrangement of the strapping bundle.
  • the initially elastic adhesive points between the articles that are touching one another when they are applied and assembled in the article assembly harden after they have been transferred to the rectangular arrangement and form non-elastic adhesive bonds between the articles fixed to one another, which then have an almost can ensure and maintain immovable bundle association in the rectangular arrangement.
  • a further advantageous option of the method according to the invention can consist in the strapping bundle being held after the application of the at least one strap and after the production of the rectangular arrangement of the article combination by a packaging blank which fixes the article tops in corresponding through-openings.
  • packaging blanks are usually made of cardboard or stiff paper material, sometimes also of plastic. They normally have expandable openings through which the neck sections of bottles, upper flanged edges of beverage cans or corresponding sections of articles to be fixed are pushed and preferably latched there by suitable structural measures.
  • the arrangement of the openings in the packaging blank which can be stretched at the edges, simultaneously defines the position of the articles, bottles or cans fixed therein, with this arrangement also corresponding to the arrangement of the articles of the container group brought into the rectangular arrangement.
  • such packaging blanks or so-called top clips or other solutions for fixing the position of the bottles and/or for creating a handle function can be used.
  • the invention proposes, in addition to the method explained in different variants, a strapping bundle that comprises at least three, in particular similar, grouped articles that are held together by strapping, wherein the strapping bundle can be produced in particular by means of a method as explained above .
  • the articles that are to form the strapping bundle have at least one of the strapping encircled area each cylindrical or approximately cylindrical lateral surface sections.
  • the strapping is formed by at least one prefabricated, closed strapping band, the length of which corresponds approximately to the total circumference of the article combination located in a diagonal arrangement or dense ball packing when the at least one strapping is attached.
  • the article assembly together with the strapping surrounding the articles in the horizontal direction is brought into a rectangular arrangement with elastic stretching of the strapping, with the closed strapping being subjected to a defined strap tension that mechanically stabilizes the bundle.
  • the prestressing force of the strapping band is generated by an increase in the overall circumference of the article combination forming the strapping bundle when it is transferred into the rectangular arrangement and/or by deformation and/or compression of the articles in the jacket areas on which the strapping band is guided.
  • the strap must be elastically stretchable in the longitudinal direction.
  • the strapping band can be formed, for example, by a plastic band, by a paper or cardboard band with welded and/or glued and/or clamped overlapping end sections.
  • the strapping band is preferably formed by an endless material without a connection point.
  • the strapping may, for example, be cut from a tube and may be formed of, for example, plastic strapping or reinforced pulp/paper strapping. Tape materials made of plastic, paper, cardboard, metal, molded fiber parts or other flexible materials are also conceivable.
  • the articles can also be made for the articles to be transferred at least at some of their contact points, at which their lateral surfaces are in the Rectangular arrangement of the strapping are touching each other, are equipped with splices or adhesive strips, so that the articles remain without external influence with pre-stressed strapping in the rectangular arrangement.
  • the adhesive spots between the articles that are touching one another and that are elastic when the articles are applied and put together can preferably be hardened after the articles have been transferred into the rectangular arrangement and thus form non-elastic adhesive connections between the articles fixed to one another.
  • the strapping bundle is equipped with a packaging blank that fixes the individual articles of the combination of articles by a packaging blank that fixes the article tops in corresponding through-openings, so that the articles are additionally fixed by this packaging blank and held in their relative positions to one another.
  • So-called top clips or other solutions for fixing the position of the bottles and/or for forming a handle function can be used as such an option.
  • the invention also proposes a strapping machine in addition to the method explained in different variants and in addition to the strapping pack described in different variants the features of independent claim 8.
  • the strapping machine according to the invention is used to produce strapping bundles from combinations of at least three articles, in particular of the same type, which are held together by strapping. At least in an area encompassed by the strapping and/or in areas where adjacent articles touch, the articles each have cylindrical or approximately cylindrical lateral surface sections.
  • the strapping machine according to the invention comprises at least one transfer tool for applying prefabricated, closed strapping strips to the item combinations located in a diagonal arrangement.
  • the strapping machine includes at least one reformatting tool for converting the items located in a diagonal arrangement, together with the strapping that surrounds the items in the horizontal direction, into a rectangular arrangement.
  • the strapping machine according to the invention can run in a continuous conveying operation, which means in particular a processing operation without stopping the article combinations during the application of the strapping bands.
  • strapped packs can be formed by transferring several parallel rows of articles or beverage containers that are transported one behind the other and that are initially in a ball pack or diagonal arrangement.
  • Several rows e.g. three parallel rows

  • the individual rows with articles or containers are guided in aisles, which aisles each have an appropriate width so that the articles or containers conveyed in the transport direction do not have any significant friction effects can be moved through between the rows or lanes laterally separating vertical lane plates.
  • the desired number of articles or containers can be separated from the rows that are transported without gaps by suitable dividing devices, e.g. by dividing rods held on circulating chains, which engage transversely to the transport direction behind the article grouping to be separated from the following articles or containers by a gap and pull this with move at least briefly higher feed rate than the conveying speed of the horizontal conveyor forward.
  • suitable dividing devices e.g. by dividing rods held on circulating chains, which engage transversely to the transport direction behind the article grouping to be separated from the following articles or containers by a gap and pull this with move at least briefly higher feed rate than the conveying speed of the horizontal conveyor forward.
  • the separation of a desired number of articles or containers from the uninterruptedly transported rows can also take place, for example, by dividing fingers emerging from below through the conveying or support plane.
  • Such dividing fingers can in particular be formed by pairs of vertical rods engaging from below in each row, which are preferably guided in the vicinity of the aisle plates and, after they have emerged in the conveying plane, to form the desired gap at an at least briefly higher feed speed than the conveying speed of the horizontal conveyor device move forward.
  • An optional further pusher device with a pusher bar that acts from behind on the article grouping separated by the dividing device can, if necessary, in the further course of conveyance, in cooperation with tapering outer railing sections of the aisle plates, ensure that the e.g. a total of six articles or containers are pushed together in a diagonal arrangement.
  • the push bar can have a stamp-like projection or the like approximately centrally on the front side facing the article grouping. which pushes the two middle articles or containers of the pusher device acting on the rear of the group of articles relative to the two outer pairs of articles by a defined feed path forwards in the transport direction, with this defined feed path sensibly corresponding to approximately half the article or container diameter, because thus the closest sphere packing or diagonal arrangement can be achieved.
  • the outer railing sections which taper on both sides, simultaneously push the respective outer pairs of articles or containers onto both longitudinal sides of the middle pair of articles or containers, which had previously been pushed by about half the article or container diameter compared to these two outer pairs of articles or containers by means of the stamp-like projection on the push bar forward in the transport direction on the horizontal conveyor, so that the total of six articles or containers (or a correspondingly different number, depending on the desired size of the article composition) of the article grouping treated in this way touch on their shell sides as soon as they are brought into the spherical packing of the diagonal arrangement became.
  • the selected distances between the outer railing sections from one another in the further conveying process no longer allow this ball pack to move apart, at least until the diagonal arrangement is shifted into a rectangular arrangement in a later processing stage after the strapping has been attached.
  • a continuous further movement of the total of six articles or containers of the article grouping while maintaining the diagonal order achieved can be effected by gripping from the rear of several push fingers, which can be moved out of the push bar in the horizontal longitudinal extension and perpendicular to the longitudinal extension direction of the push bar and parallel to the transport direction in the positive transport direction, two pusher fingers each being able to grip the rear left and right edges of each of the rear three articles or containers of the article grouping.
