Description

The present invention relates to a method for producing a container from among themselves adhesively bonded articles according to the features of the preamble of claim 1.

It is known to first provide articles such as PET containers (PET: polyethylene terephthalate) with an adhesive and then press them together to thereby produce a package of several articles.

Each article of a bundle of several articles has a footprint serving as footprint of the article, a cover surface spaced from the base surface by the normal height of the article, and a lateral surface connecting the circumference of the footprint to the circumference of the top surface.

In order to produce from several, for example, identical items a container of several interconnected by an adhesive article, it is necessary to provide the articles at their abutting in the finished container surfaces with the adhesive and then the provided with the adhesive surfaces of the to press the adhesive container together to press the article together.

These abutting surfaces in the finished container are generally parts of the lateral surfaces which, in comparison with remaining parts of the lateral surfaces typically the greatest distance from a central axis extending from the center of gravity of the base to the center of gravity of the top surface, along which the centers of gravity of all following, running parallel to the base cross-sectional areas of an article have.

The in the finished container abutting surfaces of the article comprising parts of the outer surfaces of the articles are provided with the adhesive by this point and / or line and / or area applied before subsequently grouped the articles according to their arrangement in the finished container and be pressed against each other at least for a short residence time, for example, until a curing agent requiring a curing time has produced an adhesive bond between the articles, which withstands a load in the further handling of the container.

As adhesives are used either during the pressing together in their outer shape invariable and / or reversibly variable adhesive, such as adhesive strips, which have the disadvantage of a high cost in their handling during the manufacture of a container, or such adhesives, which during the juxtaposition irreversibly plastically deformable, such as, for example, first liquid or pasty adhesives, which harden after a certain time and / or harden and manifest a hitherto assumed outer shape. The latter have the advantage of a simple, for example by means of spray nozzles non-contact applicability in the manufacturing process, but the disadvantage that they are in their juxtaposition for bonding with each other to a container both in articles whose outer shape is not rigid, as well as in articles with a rigid outer shape, can be easily displaced and / or pressed flat so that their adhesion is greatly reduced at least on a lateral surface of two mutually by the adhesive to be joined together article.

In particular, in articles whose outer shape is not rigid at least in terms of their lateral surfaces, but rather, for example, elastically deformable, such as thin-walled containers and / or uninvoked container, such as filled with an unfavorable liquid beverage bottles, such as PET containers, results in addition the disadvantage that they are deformed when pressed against each other. Due to the adhesive, it may then happen that the article or its deformation does not go back to its original shape even after releasing. The disadvantageous consequence is deformed articles as well as different dimensions of containers made of identical articles bonded by an adhesive because of different rebounding of the articles in the different containers.

By DE 23 31 193 is a container of arranged at right angles to each other rows and rows arranged articles whose articles are connected by an adhesive directly to each other. The items may be cans or bottles.

By DE 203 10 721 U1 is a container made by means of an adhesive directly interconnected articles in a nested arrangement known. The adhesive may comprise an adhesive or an adhesive strip. The adhesive may be applied in the region of a cylindrical portion of an article over its entire circumference or over its entire height.

By DE 10 2009 044 271 A1 It is known to provide in the finished container abutting surfaces to a container compiled article with an adhesive and thereby stick together. The articles are about PET containers. The container may be provided with a casing which surrounds the articles of the container on its periphery. The enclosure has at least one strapping.

DE 10 2011 106 759 B3 describes a method for producing containers from articles provided with an adhesive, which are directly connected to one another.

The object of the invention is to provide a method for producing a container from each other by an adhesive connected articles, which is at least partially free of the disadvantages of the prior art.

The above object is solved by the features of the independent claim. Further advantageous embodiments are described by the subclaims.

A method of producing a package of articles adhered to each other by at least one adhesive comprising, for example, one or more adhesives, each article having a base surface as the footprint of the article, a top surface spaced from the base surface by the normal height of the article, and a lateral surface which connects the circumference of the base surface with the circumference of the cover surface, in particular of articles whose outer shape is not rigid at least with respect to their lateral surfaces, but rather is elastically deformable, for example in the article, such as PET containers, with at least one adhesive be provided and then pressed together to thus produce a container of several articles, sees during the pressing against each other to be bonded article at most a substantially only point and / or line-shaped Contact the lateral surfaces of briefly referred to as splices games of the base and top surfaces of the article on the circumference respectively connecting lateral surfaces comprehensive or covered by these surfaces before, at which the articles at least approximately directly touching each other in the finished container and / or only to the adhesive abutting one another and / or separated from each other in the finished container merely by the adhesive to ensure that the adhesive when pressing against each other at least on one side, preferably on both sides of itself in the region of the splices located contact points, where the articles manufacture each other in the finished Immediately contact punctiform and / or line-shaped containers and / or have a smallest distance bridged by the adhesive in the finished container, assumes a spatial extent, which in addition to and / or deviating from a least on a lateral surface extends a first article expansive film adhesive away from the lateral surface of the first article to the lateral surface of at least one second article.

The at least one adhesive is preferably an adhesive which is initially or irreversibly plastically deformable, such as, for example, first liquid or pasty adhesives which harden and / or harden after a certain time and manifest a previously taken outer shape.

It can be seen that the invention can be realized by a method for producing a container from among themselves adhesively bonded by at least one adhesive articles, which provides that the article - after they have been provided with adhesive - only so far approach each other that, although an immediate point - And / or linear contact between the lateral surfaces of the article and / or an indirect, separated by adhesive contact between the lateral surfaces of the article, but no deformation of the article takes place.

The maximum punctiform and / or linear contact can be ensured by the articles are only so far approached when pressed against each other until a direct and / or only separated by the adhesive, indirect contact between the articles takes place at the intended splices. A further approach, in which the articles at least temporarily change their outer shape, whereby the adhesive applied to the lateral surfaces of the adhesive flattened and distributed over the lateral surfaces of the articles and thereby thinned to a film in extreme cases, to none for the connection of articles to A container sufficient adhesive effect emanates from the thinned adhesive more is prevented in this case. This can be done, for example, by way monitoring of the articles when they are pressed against each other, or by an optical, for example, video sensorial monitoring of the pressing process, or by monitoring the Kraftverlaus taking place for the purpose of juxtaposition movement of the article towards each other, or by a combination of two or more different and / or same monitoring, to name just a few conceivable embodiments.

Alternatively or additionally, the punctiform and / or linear contact can be ensured by placing the articles under an overpressure relative to the environment, so that they occupy an outer shape that is largely invariable, at least when pressing against each other, which results in a planar displacement up to Thinning of adhesive in extreme cases up to a film excludes.

An overpressure can be generated, for example, by squeezing the articles to be pressed against each other at least during pressing against one another from a side facing away from the splices, so that a volume available for their content is reduced. As a result, the articles experience a stiffening of their outer shape on their sides facing the splices, whereby they develop a resilient resistance to deformation due to pressure loading in the region of the splices during pressing and can be deformed less or not at all.

The method therefore preferably provides for at least two articles provided with adhesive at least on a part of their splices and aligned at least in accordance with the splices provided with adhesive in accordance with their subsequent arrangement in the finished package and at least at least at the splices facing each other and at least partially provided with adhesive for a short dwell, wherein there is at most only point and / or line contact of the lateral surfaces in the region of the splices with at least partial lateral displacement of a portion of the adhesive to the contact points covered by the splices, so that one or both sides the contact points preferably results in a bead of adhesive which extends in the region of the splices of the lateral surface of a first article to the lateral surface of a second, to be bonded to the first article article.

The in the finished container abutting surfaces of the article comprising parts of the outer surfaces of the article can be provided with the adhesive by punctiform and / or linear and / or surface contactless, for example by means of one or more spray nozzles, or by contact, for example by means one or more rollers and / or wheels, for example, at the periphery of adhesive exits, is applied.

The method may provide, after at least a portion of the splices of the articles to be joined together with adhesive, to group the articles according to their arrangement in the finished container and to press together at least for a short residence time, for example until a curing time required adhesive has made an adhesive bond between the articles, which withstands a load in the further handling of the container.

The articles are preferably articles whose outer shape is elastically deformable, at least with regard to their lateral surfaces, such as thin-walled containers and / or uninflated containers, such as plastic bottles filled with unfavorable liquid, such as PET containers.

An article of a container, as already mentioned, serves as a contact surface of the article, for example circular or oval or regular or irregular tri-, quadrilateral or polygonal base area, for example identical or similar or congruent to the base area in a mathematical and / or geometrical sense the normal to the base surface extending height of the article from the base surface spaced top surface, and a the periphery of the base surface with the circumference of the top surface connecting lateral surface. From the center of gravity of the base surface to the center of gravity of the top surface extends a central axis, along which central axis are the centers of gravity of all successive, lying parallel to the base cross-sectional areas of the article.

For example, a central axis can be defined as a continuous or unsteady mathematical curve on which the centers of gravity of all successive cross-sectional areas of the article lie. Out of this possible discontinuity, there is the possibility that the article has different central axes in successive sections or regions, which is why, if hereinafter referred to as a central axis, it may be at least one central axis.

This results in an essentially cylindrical shape for an article, but over the height of the article variable geometries of the successive, parallel to the base surface cross-sectional areas may have, for example, a cone, a truncated cone or a combination of cylinder and / or cone and / or truncated cone. Also, the cross-sectional areas may be arranged offset to each other at least in sections over the height of the article in the direction parallel to the base surface, similar to a skewed cylinder. In principle, any, for example, organic forms, be it as part of or as a whole of the outer shape of an article conceivable.

Base and top surface can be arranged in parallel, but also obliquely to each other, as is known for example by running as a beverage container in the form of a beverage carton articles.

In an article designed as a container, such as a beverage container in the form of a bottle, the entire top surface may be replaced by a bottle for example, be closed by means of a lid closable opening.

The splices comprising the contact points may be parts of the lateral surfaces which, in comparison with remaining parts of the lateral surfaces, are typically the greatest distance from a central axis extending from the center of gravity of the base surface to the center of gravity of the top surface, along which the centers of gravity of all succeeding ones are parallel to the base surface extending cross-sectional surfaces of an article, have.

It is important to emphasize that containers are conceivable, for example, irregularly shaped articles in the range of games whose lateral surfaces collide or have splices, which are closer to the central axis in a first article, as remaining parts of the lateral surface of the first article, and a second Article furthest from the central axis are, or include in one and the same article a first batch which is closer to the central axis, as in relation to the first batch remaining parts of the lateral surface, and a second batch, which is also the central axis , as in relation to the second lot remaining parts of the lateral surface of the same article.

The splices may include one or more glue dots and / or glue lines. At an adhesive point, an article is punctually provided with the adhesive, for example, by the adhesive is applied punctiform on a corresponding portion of the lateral surface of one or more articles. At an adhesive line, an article is provided with the adhesive along a line preferably extending parallel to the central axis of the article, for example by applying the adhesive linearly to a corresponding portion of the lateral surface of one or more articles.

The method may provide for arranging the articles of the container, for example, in a row in a straight line one behind the other, or to regularly arrange the articles of the container in rows and rows running at right angles to one another.

To summarize articles with partially cylindrical or approximately cylindrical shapes such as. Beverage cans or bottles, as compact as possible and with minimal relative mobility to each other, the method may provide that the article in the finished container form a so-called honeycomb or spherical composite, which is also a nested arrangement referred to as. In this case, the articles arranged in adjacent rows in the container are each offset from one another in such a way that the gaps formed between the articles are as small as possible. The lines do not run at right angles to the rows, but diagonally. The lines can be straight or V-shaped angled, or zigzag angled run obliquely to the rows. Such a honeycomb or ball assembly represents a composite of a given number of articles with the least possible footprint.

In summary, the articles may be arranged in the container in a row, for example linear or rectangular or nested. A mixed arrangement is conceivable, depending on the design of the container.

The method may additionally provide a container comprising a plurality of articles adhesively bonded to one another by means of an enclosure which surrounds the articles of the container at its periphery.

Alternatively or additionally, the method may provide for a container consisting of a plurality of articles adhesively bonded together by means of adhesives, free from encasement or encircling, to be provided with a carrying handle to facilitate the handling of the container. The carrying handle can be arranged for example on the enclosure and / or on one or more articles of the container.

The method may provide for initially providing at least a part of all splices of the articles to be joined to a container with at least one adhesive.

Preferably, at least half of the surfaces in the finished container abutting surfaces of the articles or encompassed by these, designated as splices of the outer surfaces of the articles provided with adhesive by punctiform or linear, for example by means of one or more spray nozzles on the corresponding part of the Entity of all splices is applied before subsequently the articles are grouped by degrees or at the same time according to their arrangement in the finished container and pressed together, at least for a short residence time, for example, until a curing agent requiring a curing adhesive has made an adhesive bond between the articles which withstands a load in the further handling of the container or the previously completed part of the container.

Alternatively, the surfaces of two or more articles of the package enclosed by the splices, which abut one another in the finished container, can all be provided with adhesive. alternative or additionally, in each case only one of the surfaces of two or more articles of the container which abut one another in the finished container can be provided with adhesive.

As already mentioned, the method can provide that the adhesive is applied without contact, for example by means of spray nozzles.

According to the invention, a plurality of splices arranged, for example, distributed over the circumference of an article at one or more different heights, can be provided with adhesive at the same time.

In order to provide adhesive with adhesive to each other to a container to be bonded to at least a portion of their splices, can be moved to one or more sections at least one transport path along which at least one at least one splice to be provided with adhesive article, several individually controlled Devices are arranged, such as spray nozzles, with which the various splices of the articles to be joined to a container can be provided with adhesive in each case.

After at least some of the contact points of the articles to be bonded together to form a container have been provided with adhesive or already before, the method may provide for the articles to be joined together by means of an adhesive, one after the other or at the same time from one or more article streams For example, in each case immediately moving away from each other moving articles in groups and / or to separate.

After the articles have been adhesively attached to at least a portion of their splices and the articles have been separated and / or singulated from one or more article streams before or after, the method may provide for aligning the articles at least in accordance with the adhesive splices.

If the method does not provide for simultaneously affixing a plurality of splices arranged, for example, over the circumference of an article at one or more different heights, the method may, after aligning the articles, provide at least one further part of the totality of all contact points of the one bundle to provide adhesive to the article to be joined and, if appropriate, reorient the articles thereafter. This process can be repeated in accordance with the number of splices distributed over the circumference of an article and to be provided with adhesive.

In other words, it is conceivable, after a splice at one level of an article or after two or more splices were provided at different heights of an article with adhesive, and the article still one or more, further splices for connection, for example, with other, adjacent in the finished container Articles to re-align the article according to the splices that have not yet been provided with adhesive and to provide at least a portion of the splices of the aligned articles with adhesive.

Finally, after at least that part of the totality of the splices of at least two articles to be joined into a bundle, which is part of the totality of the splices, has been completely provided with adhesive before the articles are combined into the bundle, the method provides Subsequently, bring together the at least two at least on a part of their splices provided with adhesive and at least correspondingly provided with adhesive splice articles according to their subsequent arrangement in the finished container and at the facing and at least partially provided with adhesive splices at least for a short Retention time under no more than point and / or line-shaped contact of the lateral surfaces in the region of the splices to each other, for example, so long until a curing time required adhesive an adhesive bond zwis has manufactured the articles, which withstands a load in the further handling of the container.

Further, also to the container to be joined with articles can gradually, as well as they are provided at the corresponding splices with adhesive, which are initially supplied by the first two items to date finished part of the container and to the facing and at least for Part with adhesives provided adhesive to the previously completed part of the container are also pressed at most only point and / or linear contact of the lateral surfaces in the region of the splices, so that the previously completed part of the container continues to grow until the Container has reached its final number of articles in the appropriate arrangement.

As an alternative to a described procedure, in which the container to be finished grows article by article, at first all articles can be involved in at least part of their splices Adhesive are provided and then all together to form a container to be joined articles at the same time or at least approximately simultaneously brought together and pressed at most only point and / or linear contact of the lateral surfaces in the region of the splices against each other.

According to the method, pressing against one another is preferably carried out in such a way that contact with the lateral surfaces in the area of the splices is achieved at least partially by lateral displacement of a portion of the adhesive at the contact points encompassed by the splices, so that one or more contact points are at best only punctiform and / or linear On both sides of the contact points preferably results in a bead of adhesive which extends in the region of the splices of the lateral surface of a first article to the lateral surface of a second, with the first article to be bonded article.

It is important to mention in connection with the present invention that the expression pressing against each other in the sense of the invention by no means mandatory exercise of a force, but rather an approximation to the mentioned point and / or line-shaped contact of the lateral surfaces of the facing adhesive joints optionally below Partially irreversible and / or reversible displacement of adhesive at the contact points covered by the splices.

In the following, embodiments of the invention and their advantages with reference to the accompanying figures will be explained in more detail. The proportions of the individual elements to one another in the figures do not always correspond to the actual size ratios, since some shapes are simplified and other shapes are shown enlarged in relation to other elements for better illustration.

10 a bundle of articles mutually interconnected by at least one adhesive at splices in a perspective view which, after its articles have been joined together by an adhesive, is encased in the form of a strapping at the level of a taper of its articles and with a carrying handle to facilitate handling was provided with the container, in a perspective view.

An in 1 to 10 completely or partially presented container 01 consists of several articles 02 which by an adhesive 03 at splices 04 are interconnected.

An article 02 a container 01 has a footprint of the article 02 serving, for example, circular or oval or regular or irregular three, four or polygonal base 05 , for example, the base area 05 in mathematical and / or geometric sense identical or similar or congruent to the normal to the base 05 extending height H of the article 02 from the base 05 spaced top surface 07 , as well as the scope of the base area 05 with the circumference of the top surface 07 connecting lateral surface 08 on. From the geometric center of gravity of the base 05 to the geometric center of gravity of the top surface 07 extends a central axis 09 , along which central axis 09 the centers of gravity of all successive, parallel to the base area 05 lying cross-sectional areas of the article 02 lie.

In an article designed as a container, such as a beverage container in the form of a bottle 02 , can the entire deck area 07 by an example by means of a lid 10 closable opening can be taken.

One or more articles 02 can be above and / or below a splice 04 be tailored. For this purpose, the lateral surface 08 an article 02 a section with a rejuvenation 06 have their scope.

An outer shape of the article 02 is at least with regard to their lateral surfaces 08 preferably not rigid, but rather, for example, elastically deformable, as for example in exported as a PET container for unbegaste liquids articles 02 the case is.

At the splices 04 are lots of land 05 and deck surfaces 07 the item 02 at the periphery of each connecting lateral surfaces 08 areas covered or encompassed by the articles 02 or their lateral surfaces 08 each other in the finished container 01 touch at least approximately directly and / or only to the adhesive spaced from each other abut and / or in the finished container 01 only by adhesive 03 are connected to each other separately.

In the field of splices 04 are contact points 11 to which the articles 02 each other in the finished container 01 touch directly and / or in the finished container 01 by dashed lines 12 in 2 B ) and c), 3b ) and c), 5 . 6 . 8a ) and b) indicated, a smallest, by adhesive 03 Have bridged distance.

To a predetermined number of articles 02 through an adhesive 03 with each other to a container 01 To connect, the articles become 02 at least a part of the totality of their splices 04 with adhesive 03 and then pressed together to form a container 01 from several articles 02 to create.

The adhesive together 03 to be bonded together and thus to be joined articles 02 However, during the pressing against each other, they are only moved so far toward one another that at most one contact, which is essentially only punctiform and / or linear, projects its lateral surfaces 08 at the splices 04 takes place.

This will ensure that the adhesive 03 when pressing against each other at least on one side, preferably on both sides of itself in the region of the splices 04 located contact points 11 a spatial extension 13 occupies, which in addition to and / or deviating from a on a lateral surface 08 at least a first article 02 Stretching film adhesive 03 away from the lateral surface 08 of the first article 02 up to the lateral surface 08 at least one second article 02 extends, as in 3 . 8th and 9 is shown.

This spatial extension 13 can through a bead 14 be formed, which by a partial displacement of the adhesive 03 in the area of contact points 11 arises and is either on one side of a contact point 11 trains, or as in 3 . 8th and 9 represented on both sides of a contact point 11 ,

About the height H of an article 02 There are several splices 04 be provided as in 1 . 2 . 3 . 4 . 7 . 9 shown.

At the contact points 11 comprehensive splices 04 may be parts of the lateral surfaces 08 act, which in comparison with remaining parts of the lateral surfaces 08 the largest distance from one from the center of gravity of the base 05 to the center of gravity of the top surface 07 extending central axis 09 , along which the centers of gravity of all successive, parallel to the base 05 extending cross-sectional areas of an article 02 lie, have.

It is important to emphasize that also containers 01 are conceivable, for example, the irregularly shaped article 02 in the area of parts of their lateral surfaces 08 collide or splice 04 exhibit that at a first article 02 closer to the central axis 09 lie, as remaining parts of the lateral surface 08 of the first article 02 , and a second article 02 farthest from the central axis 09 lying away, or in one and the same article 02 include a first batch which is closer to the central axis 09 lies, as in relation to the first batch remaining parts of the lateral surface 08 , and a second lot, further the central axis 09 lies, as with respect to the second batch remaining parts of the lateral surface 08 of the same article 02 ,

Preferably, at least one adhesive 03 provided, which is initially irreversibly plastically deformable, such as an initially liquid or pasty, one- or multi-component adhesive, which cures after a certain time and / or cures and manifests a hitherto occupied outer shape. A method for producing a container 01 from each other by at least one corresponding adhesive 03 at splices 04 Associated articles provides this, the little by little or at the same time according to their arrangement in the finished container 01 grouped article 02 at least as long press until the at least one an er and / or curing time-requiring adhesive 03 an adhesive bond between the articles 02 has produced a load in the further handling of the container 01 or a previously completed part of the container 01 stops.

The maximum punctiform and / or linear contact during pressing can be ensured by the article 02 when juxtaposing, they are only approximated to each other as far as an immediate or approximate one, only by the adhesive 03 separated and / or by the adhesive 03 bridged contact between the articles 02 at the contact points 11 in the area of the intended splices 04 takes place. A further approach in which the articles 02 change their outer shape at least temporarily, causing the on their lateral surfaces 08 applied adhesive 03 Flattened and over the lateral surfaces 08 the article is distributed and thinned in extreme cases up to a film, to none for the connection of articles 02 to a container 01 sufficient adhesion of the thinned adhesive 03 more goes out, this is prevented. This can be done, for example, by way monitoring the articles 02 take place during the juxtaposition, or by an optical, for example, video-sensorial monitoring of the pressing process, or by monitoring the Kraftverlaus at a held for the purpose of juxtaposing movement of the article 02 towards each other ( 6 . 7 , or by a combination of two or more different and / or same monitoring, to name just a few conceivable embodiments.
