Definitions

  • the following relates to a method for packaging piece good combinations and a machine for packaging piece good combinations as well as a piece good combination. It has been known for a long time from the prior art that piece goods, for example containers, are bundled together into groups of containers, for example so-called six packs. Various procedures are known for this purpose. In a procedure known from the prior art these containers are packaged in a film and this film is then shrink-wrapped onto the containers, for example in a shrink tunnel.
  • a stretchable film also referred to below as a stretch film
  • the containers are introduced into a wrapping device and are wrapped there by means of a stretchable film.
  • the stretchable film is usually unwound from rolls.
  • a gripping element or a handle is usually attached at a later stage to such groupings which are already wrapped.
  • the packs which are already cut and wrapped with film are spaced apart from one another in order to apply a handle in the running direction of the pack for example by means of front and rear gluing arms.
  • An aspect relates to simplifying the attachment in particular of handle elements.
  • the aspect is in particular to simplify the production of such piece good combinations, in particular with handles.
  • a possibility should be created which makes it possible to dispense with a spacing of adjacent groups of containers for attachment of the handle.
  • a transport device transports a plurality of piece goods in particular as a stream of piece goods in a predetermined transport direction, and a first wrapping device wraps the piece goods with a film element.
  • this film element has a predetermined first width.
  • this first wrapping device has a dispensing unit revolving around the piece goods, wherein the piece goods are delivered to the first wrapping device in order to be wrapped by the film element.

  • the film element is preferably made of a plastic material and in particular a transparent plastic material.
  • the strip-like element is preferably made from a material which is selected from a group of materials including plastics, fibre materials and paper materials.
  • a width of the film element or of the strip-like element is understood to be a dimension in one direction which extends in particular perpendicular to a main extension direction of this strip or of the film.
  • This main extension direction is understood to be the direction from which for example the film element is pulled off from a film roll or also the strip-like element is pulled off from a strip roll.
  • this is the direction along which the film element or the strip-like element substantially extends.
  • the present application describes that a piece good combination wrapped with a film element is wrapped with the strip-like element. Therefore, it is pointed out that this procedure is also applicable to other pack types and in particular to shrink-wrapped packs. In this way for instance shrink-wrapped packs could be wrapped in particular uninterruptedly with the strip-like element, in particular with a handle wrapped.
  • a transport device transports a plurality of piece goods in particular as a stream of piece goods in a predetermined transport direction

  • the strip is merely wrapped around the fixed carrier and the containers already wrapped with a film element.
  • the strip-like element can be constructed both resiliently and rigidly in its longitudinal direction.
  • this strip-like element can fulfil several purposes.
  • the strip-like element could be a wrapping strip for advertising purposes.
  • the strip-like element could also be formed as a handle or could also serve both as a handle and for advertising purposes.
  • the strip-like element serves as a gripping element, it can be advantageous (so that the strip can be “gripped” in the handle region) if it does not rest too tightly on the piece good combination and or the film element.
  • a “loose” handle could be provided by a brief driven unwinding of the gripping strip with a higher unwinding speed than the normal pulling.

In this way a uniform legibility for instance of an imprint is made possible.
  • the strip-like element with a “gradient of 0”, that is to say in particular parallel to the transport direction.

In this case this pulling off can take place from one or more rolls.
  • an application to an outer or inner wrapping layer is also conceivable, possibly also first directly onto piece goods.
  • a location-related controlled build-up for “air handles” can also take place, but also a subsequent pack spacing and thus also additionally a “front” adhesion/fastening are made possible.
  • the film packaging can also be cut to length by cutting to length and, if necessary, the film packaging can be cut free in the handle region.

Furthermore, it is also conceivable that the rotational speed of the application element and the transport device which transports the piece goods are adapted to one another in such a way that the strip-like material in each case is adhered at specific positions on the film element, for instance in the region of a side wall of the piece good combination. In this way an improved hold can be achieved if the strip-like material is to be used as a grip or handle. Sections of the strip-like element are preferably also free of adhesive or are not coated with an adhesive. These may be the regions which should be gripped by a hand later.
  • the strip-like element has a lesser width than the first film element, as described above.
  • FIG. 1 shows a schematic representation of a machine for producing piece good combinations
  • FIG. 2 a shows a representation of a method according to the prior art
  • FIG. 2 b shows a container pack produced by the method of FIG. 2 a
  • FIG. 3 a shows a representation of a method
  • FIG. 3 b shows a representation of a piece good combination produced by the method of FIG. 3 a.
  • FIG. 1 shows a schematic representation of a machine 50 according to embodiments of the invention for producing piece good combinations or piece good packs and in particular container packs.
  • the reference numeral 2 designates a transport device which transports containers 10 here from left to right along a rectilinear transport path T.
  • this transport device has overall a plurality of transport units, such as in particular a supply conveyor belt 28 as well as three feed modules 22 , 24 und 26 .
  • These feed modules 22 , 24 und 26 in each case serve to pull a wrapped pack out of respective preceding wrapping devices 4 , 8 and 6 to extract and/or to deliver it to following wrapping devices.
  • the reference numeral 4 designates a first wrapping device 4 .
  • this wrapping device 4 has a carrier plate 32 onto which the containers 10 are pushed.
  • lateral guiding elements 34 are provided which laterally delimit the stream of containers.
  • Both the carrier plate 32 and the lateral guiding elements 34 are wrapped by a film element 12 which originates or has been unwound from a film roll 14 .
  • the reference sign B relates to a width of the film element 12 .
  • the reference numeral 30 identifies in its entirety a dispensing unit which revolves with respect to the containers and perpendicular to the drawing plane.
  • a transport unit 22 in the form of a feed module adjoins the first wrapping device 4 .
  • This conveys the containers, which are now already wrapped with the first film element, to a second wrapping device 8 .
  • This likewise again has a (stationary) carrier plate 32 as well as lateral guiding elements 34 .
  • the containers are wrapped with a second film element 18 , which in this case originates from a film roll 15 .
  • This film roll also revolves around the containers, albeit preferably in a reverse direction from the film roll 14 in the first wrapping device.
  • the reference numeral 24 designates a further transport unit in the form of a feed module, which transports the containers, now already wrapped twice, to the strip application device 6 .
  • This also again has an (albeit shorter) carrier plate 32 as well as lateral guiding elements.
  • the reference numeral 17 designates a strip roll, from which the strip-like element 16 is unrolled and is wound around the containers.
  • a further transport unit 26 such as a feed module, the containers are pulled out of the strip application device.
  • the carrier plate could also be dispensed with during the wrapping with the strip-like element and the piece good combination could be pushed away over the resulting gap.
  • the strip-like element could then be wrapped specifically in this gap.
  • the transport or supporting device following the wrapping with the strip-like element could have rounded surfaces or oblique surfaces which simplify bridging of the gap. Lateral guiding devices could also be dispensed with during the wrapping with the strip-like element.
  • the possibility of attaching a strip-like element 16 with an in particular uninterrupted pack transport is illustrated. Therefore, in this case for attachment of a handle no more gaps are produced between the packs.
  • the strip-like element 16 is applied spirally to the pack, in order thus to achieve the gripping of the pack ultimately produced.
  • the feed module 26 adjoins a separating device 40 , which splits the continuous stream of containers into individual piece good combinations. In this case this separating device 40 can move together with the containers, wherein preferably a movement of this separating element is synchronised with the movement of the containers.
  • the reference sign B 1 designates a width of the strip-like element 16 . It will be recognised that this width B 1 is considerably smaller than the width B of the or the film elements. Therefore, the strip-like element is preferably wound around the piece goods in such a way that adjacent turns of this winding do not touch or overlap.
  • FIG. 2 a shows a representation of the attachment of handle elements according to the prior art. It will be recognised that here the piece good combinations 110 are delivered and first a distance is produced between them, in order thus to attach the handle element 116 , for example by means of a rear and a front adhesive frame. In this way—as shown in FIG. 2 b —a pack 110 is produced with a handle 116 arranged thereon.
  • FIG. 3 a illustrates the procedure according to embodiments of the invention.
  • the piece good combinations 1 are again delivered, but the spiral strip-like material 16 is attached by the strip application device 6 (cf. FIG. 1 ).
  • the piece good combination illustrated in FIG. 3 b is produced, which likewise with the strip-like element 16 has a handle, but this is arranged here slightly inclined relative to the piece good combination. In this case this “inclination” or gradient of the length of the piece good combination to be produced and/or the number of windings required per piece good combination to be produced is preferably determined.
  • this gradient can be adjusted from “almost vertical”, that is to say an angle of approximately 90° with respect to the transport direction to “very inclined”, that is to say for instance an angle of 10° relative to the transport direction.
  • the latter can be relevant in particular for advertising imprints with almost horizontal lettering.
