Description

Sales wrapping, as well as methods and devices for their further processing The invention relates to a sales wrapper for multipacks of preferably Beverage cans, with side openings and foldable locking tabs, as well as on Method and device for the further processing of this sales wrapping.

Sales wrappings with locking tabs are known. You have opposite other sales packaging, e.g. those with a tongue lock according to OS 1 817 238, the cost-saving advantage that the blank width is approx. One can width narrower can be, and also the advertising effectiveness is considerably greater because the external loosely protrude half of their circumference from the sales envelope.

The known sales wrappings are preferably made of 0.7 mm thick Cardboard and are available as multi-unit packs to promote sales, e.g. Beer cans in sets of three, particularly suitable for self-service business.

These known sales wrappings are preferably used for packing Tin cans with a content of 0.35 liters, both soldered and flanged Bottom and lid as well as deep-drawn cans with a finished base, when packing the cans are pushed laterally into the openings of the erected casings, whereby at the same time the locking tabs are folded inwards so that they are against Place the inner lid and bottom edges of the two outer cans in a blocking manner and secure the cans against falling out of the envelope.

when packing thermoformed cans with a finished base, like them are increasingly being processed in the beverage industry, it has been shown that the lower locking tabs of the known sales wrappings, on the flat slopes the inner edges of the floor cannot find a hold to support and slide on them 81 situation occurs as soon as such a sales wrapper, e.g. filled with three cans, is held or carried obliquely by a buyer, with the consequence that the three Cans slide off the locking tab under the action of their joint weight fall out of the casing and cause damage.

Because of this uncertainty of use, this - although material-saving and also effective sales wrapping - for packing beverage cans in deep-drawn Execution did not prevail and remained on the packaging of soldered tin cans limited with flanged bottom.

The well-known sales wrappings with locking tabs in a rigid length, require that cardboard blanks must be made, the length of the locking tabs according to the type of can used for packaging Other bead dimensions on the base and lid on top than tin cans in soldered design The same volume, which makes it necessary to use the special one for each type of can Keep cardboard blanks available when for example-like it is in breweries and often occurs in bottling plants - beer cans from different manufacturers and suppliers This often leads to disposition problems and the storage costs become more expensive.

The known sales wrapper can meet the requirement for uniform Do not meet the cut for changing can types of the same volume. - - - - It Attempts have also already been made to use the well-known sales serving Use locking tabs as double-row multi-piece packaging, for example two rows to three cans or two rows of four cans, so that the wrapper has a total of 8 locking flaps As in 5, this revealed the disadvantage that the upper and lower two Cardboard side reaching the width of the can, under the total weight of the cans, arched when carried and the locking tabs lose their safety effect by buckling outwards and the cans fall out of the packaging.

The invention is now based on the object of a sales envelope create a safe packaging and convenient handling of both soldered as well as envelope filled with deep-drawn cans, and which makes it possible to work with a blank form, to be able to pack cans of both types of production and that the To simplify warehousing. It is also an object of the invention to provide this sales wrapping to design so that the double-row embodiment safe and convenient handling the filled cooling allows. The invention is also based on the object to show a method according to which the sales wrappings according to the invention at the further processing, can be handled according to the different can designs and an uncomplicated, inexpensive device for carrying out the method and To create further processing of the sales wrappings according to the invention.

These objects are achieved according to the invention in that the per se have known locking tabs at their tips bendable support tongues, and that the intended bending line for the support tongue is a pre-break or embossed line, a It is a scoring or perforating line or a line pre-marked in some other way.

This bendable support tongue makes it possible that the locking tab the different shapes and dimensions of the base and cover beads of the different Can types is adaptable accordingly.

An appropriate design of the support tongue can be round or trapezoidal The tongue height of 5 mm has proven to be particularly advantageous.

The bending line of the support tongue can be straight or curved A curve radius of 25 mm has proven to be particularly advantageous, as it enables that the support tongue hugs the sloping bottom bead of deep-drawn boxes and so the inventive braking and support effect of the support tongue is effective.

So that the spring-back effect of the cardboard material for the folded locking flap and the support tongue is used, is provided according to the invention, the per se known hinge compression of the locking tab with the raised compression curvature on the outside of the box 'opposed to the embossing line for the support tongue. In order to fully utilize the cardboard tension for the support effect of the support tongue has been proposed according to the invention, the cardboard fiber running direction and the direction of action the support tongues run parallel.

For better handling of the sales wrapper according to the invention for the single-row version - two to four cans - proposed according to the invention have been, in each side wall, immediately below the cover, two finger holes pre-punching, which enables the knob of the pack to position it comfortably and horizontally capture.

In accordance with the present invention, there is provided a two-tier work wrapping formed from a blank in such a way that the vertical cardboard center web as a connecting support serves between the base and the cover of the casing the ¢ influence of the can weight bulges through the cover side, for example when carried and the locking tabs So that the cans freeze.

A practical further development according to the invention of the two-row sales envelope provides for two grip tabs already pre-cut in the cardboard blank to be attached in such a way that one flap is a direct extension of the vertical cardboard center bar and the second tab is attached to the adhesive flap of one half of the lid. These double handle extension in connection with the supporting cardboard center bar when wearing the sales wrapper filled with eight cans, for example, sufficient Safety, and the pack can be comfortably carried horizontally without the weight of the can acts on the locking tabs.

The inventive solution to the problem also posed To develop a method according to which the sales wrappers according to the invention the different can designs can be handled by the sequence the following process steps marked a) the fully glued, flat in the Erect magazine upright sales wrappings in filling position b) the Support tongues according to the invention by means of adjustable pre-crushing runners optionally, depending according to the type of can to be packaged, along the pre-marked bending line at an obtuse angle or bend at right angles or unbent in the same plane as the locking tab leave; c) Locking tabs with support tongues by means of press-down springs or blown air or some other means of removing the hinge compression line of the locking tab from the horizontal Swivel level at least 450 towards the inside of the packaging; d) Set of cans in the two Press in the side openings of the sales wrapping, while at the same time turning it again the locking tabs with the support tongues into the interior of the envelope until the support tongues close to the inner bead edge of the can base and lid.

In addition, a suitable, uncomplicated solution is part of the task at hand and inexpensive to manufacture device for performing the aforementioned method and to create further processing of the sales wrappings according to the invention. According to the invention this object is achieved in that a stack magazine for receiving of the flat wrapping blanks; and on both sides of it in the same plane and can conveyor belts running parallel to one another; and above and synchronously with them guide belts running underneath the erected wrappings as well as synchronously these, but running around perpendicular to the transport plane, on both sides of the erected Wrappings, inclined cam conveyor belts for pressing the cans into the side openings of the casings are provided.

The advantage achieved by the device according to the invention is there especially in the fact that the entire packaging process runs smoothly and synchronously and does not have any machine elements that are moved back and forth in a clocked manner Fast work sequence that corresponds to the speed of the upstream filling machine.

hs is also a relatively cheap manufacture of such devices, which are set up in breweries or other bottling plants, for example.

To the device according to the invention for packaging the most diverse Multipacks, with can sets of two to eight cans, are to be made suitable according to a further embodiment of the invention, the guide rails of the can conveyor belts and the inclined cam conveyor belts and the side guide rails of the stacking magazine can be adjusted by means of adjusting tabs, adjusting slots and locking screws arranged.

The device for carrying out the method according to the invention also provides four angle-adjustable pre-crushing runners, which are used in the transport area flow of the erected envelope blanks are attached so that äe a pre-crushing skid in the area of the two upper and the two lower support tongues comes into effect The support tongues run past these stationary pre-crushing runners and are preserved there the desired bend in accordance with the can design, and there are also four Lowering springs in the area of the two upper and the two lower support tongues fixedly attached, so that the locking tabs passing it with the support tongues be bent forward by about 450 and then in this state by the laterally brought up Cans are acted upon.

Another embodiment of the device according to the invention provides that Infeed stars rotating synchronously with the two inclined conveyor belts are provided, which have the effect that the can set to be packed an exact row formation forms.

Likewise, in order to comply with a complete packaging set, scanning elements are used for Example photoelectric, in the area of every can transport route and also in the area the transport route of the erected sales wrappings is provided during the interruption of the flowing can and blanks replenishment give a signal and the system possibly electrical switch off.

According to Figure 1, the blank of a sales wrapper consists of a single row Execution, from the two side walls 1,2, the cover part 3, the bottom part 4 and the adhesive flap 5, which receives the adhesive application 6. Have lid and bottom part two locking tabs 7 with adjoining support tongues 3, with folding lines 9 and bending lines 10 for the support tongues. The side walls in which the finger holes 11 are pre-perforated or punched-finished, as well as the adhesive flap 5 are by means of Fold lines 12 -5 5 connected to each other and form when glued together and erected an envelope, as shown in Fig.6 and Fig.15. When folded flat In the state, the two side walls 1, 2 lie against one another, as shown in FIG.

Figure 2 is the blank of a two-row sales wrap, the is formed from the adhesive flap 16, on the bending line 17 of which the one cover part 18 with the pre-perforated or punched-out tab 19 adjoins it, through Bending line 20 connected, depends on the side wall 21, which is connected by bending line 22, one bottom part 23 and connected to it again by bending line 24, the vertical one Central web 25 follows, at the bending line 26 of the second cover part 27, with the second pre-perforated or punched-out grip tab 28 and then again, connected by bending line 29, the second side wall 30 hangs from the second bottom part 3d and the adhesive flap 32 and the bending lines 33,34. Each on the base and cover parts 18, 23, 27 and 31, connected by the folding lines 39, close the locking tabs 7 and, in turn, the support tongues 3 connected to it by bending lines 10. In the glued together State and open, the blank results in the envelope, as Fig. 4 and Fig. 14 shows.

In the folded flat state, the two side walls 21, 30 rest on Central web 25, as Fig.3 shows. To ensure the stability of the support tongues 8, the cardboard fiber running direction in the direction of arrow 35 of the blanks according to Fig.1 and 2 run.

7 shows the situation in the bottom part 36 of a deep-drawn can, and the locking effect of the locking tab 7 folded around the folding line 9 with the support tongue 8 in function with the flat slope of the bottom edge37.

The can weights of a sales wrapper packaged, for example, with three cans 38 'are represented by arrow 39 and are effective when the pack is held at an angle is, so on the locking tab 7 and the support tongue 8, as in the force diagram Fig. 8 Darge represents. In it, arrow 4o represents the force absorbed by locking tab 7 represents that on the flat bottom slope 37 a pressure, shown by arrow 41 and exerts a downward force, represented by arrow 42. This latter Force 42, which becomes greater the flatter the bottom slope 37 is made, caused when using the previously known sales wrappings without a support tongue, sliding off the locking tab 7 on the slopes 37 of the deep-drawn bottoms, so that these cans from the Feel out the packaging as soon as the pack has been tipped. Only the invention Support tongue 8, which by means of the resilience of the folding line 9 of the floor slope 37 adapts and is supported on the bottom part 4, prevents the locking tab from slipping off 7 and thus enables the sales packaging to be used for safe packaging of deep-drawn beverage cans.

In order to use the full spring action of the folding line 9 for the locking tab 7 is preserved, the raised bulge of the folding line 9 is on the outside of the box 43, as Fig.9 illustrates, to be attached.

The pre-stamped bending line 1o for the support tongue 8, however, is around serve to achieve good contact against surface 37, with the compression groove 10 on the outside of the box 43 to execute.

As FIGS. 10-13 show, the support tongue according to the invention can 8 have different shapes. A preferred shape is shown in FIGS. 11 and 12, wherein the support tongue 8 has a round tip, the height "H" of which is 5 mm as special has proven suitable for the common deep-drawn jars. Furthermore, the round Bending line 10 for the support tongue, with a radius "Rn of 25 mm, has been tried and tested. Like that Fig. 10-13, the tip of the support tongue should have a cutting edge of at least 5 mm 44 tower above.

FIG. 14 shows the wrapping in a row of bumps filled with six cans with the upright carrying straps 19 and 28.Fig.16 shows the can arrangement of double-row wrapping with eight dozen. Fig. 15 shows the one filled with three cans Wrapping with finger gripping holes below the top 3 within easy reach 11. Fig.

17 represents the smallest unit with two cans.

To illustrate the packaging process and how the Locking tabs 7 and the support tongues 8, the Fig.18-20, which are a single row Shows three-pack with sieve doses. The cans 47,48 and 49 are laterally in the openings 50,51 of the sales envelope are inserted in the direction of arrows 52,53 and push the already about 45 slanted locking tabs in this organ 7 nit the support tongues 8 located thereon in front of you, so that these are around the Fold folding lines 9 in the direction of arrows 54. After inserting the 19 with the two cans 48, 49 shown cut open, the final blocking position recognize the locking tabs 7 with the support tongues 8. For the can lid 55 with vertical Bead edge 56, the support tongues 8 are adapted to the large bead diameter and are in a straight line with the pearl tabs 7. For the deep-drawn base 36 is On the other hand, the support tongue 8 angled to the locking tab 7 and hugs against the bottom slope 37 and is supported against the bottom part 4.

In FIG. 20, the top view of FIG. 19 is along the section line 57, 58 shown with the omission of the cans.

sig.18-20 show that the sales wrapping shown is 38 at any time also for cans in soldered design, with flanged lid and bottom can be used by the support tongues 8 for the can bottoms, not as in 18 are shown angled opposite the locking tabs 8, but like the two upper support tongues 8 remain in a straight line extension to the locking tabs 7. This measure allows a uniform cut for the different Can types are used, the support tongues 8, optionally the different Bead edges and diameters of the lids and bases can be adapted. the This innovation achieved simplification of storage and cutting and Can procurement helps significantly reduce the costs of performing the process according to the invention necessary device, provides for the angular pre-breaking of the invention Support tongue 8, four pre-crushing runners 59 adjustable in angle, which, like FIGS. 21-23 show that the support tongue 8 can bend at an angle with respect to the locking tab 7 Pass the blanks in the direction of the arrow of the preliminary runners.
