Description

Heating system, packaging device and method for adapting a heating system

The present invention relates to a heating system having the features of independent claim 1 and a packaging device having the features of claim 11. In addition, the invention relates to a method for adjusting a

Heating system with the features of independent method claim 13.

In the packaging industry, especially when packaging a

Compilation of the same or different articles in one

Cardboard packaging, the cardboard boxes used are at least partially glued. For this purpose, both hot glue systems and cold glue systems are used depending on the different requirements.

Traditional hot glue systems include a tank in which glue granules or other suitable adhesive is manually filled as needed. This granulate or adhesive is melted in the tank, removed from the tank via heated hoses and nozzles or gun modules and applied to the cardboard, for example, sprayed. The process is often controlled by the anyway

existing machine control. Since in the conventional, known from the prior art tank systems always the entire tank contents must be melted in order to obtain a homogeneous Leimmasse, the energy efficiency of these devices is very low. Such a system is described, for example, in document US

2013/0001239 A1.

Furthermore, what are known as "tankless" systems are known, which have a significantly smaller tank, with an automatic filling system, for example with automatic filling and continuous granulate delivery, from a single tank

large-volume reservoir, the level in the (small) tank is always kept largely at a predefined level. This saves energy and material. These so-called "tankless" systems have in particular a minimized

Melting unit, which - as an alternative to a conventional tank unit - works comparable to a water heater and only the amount of glue actually required on

Processing temperature holds and provides. In particular, the warm-up time of the system is significantly reduced to operational readiness compared to conventional tank systems. By the needs-based processing of glue granules is a Reduction of energy consumption realized. The tankless systems have a much higher melting capacity with a shorter device size and a shorter warm-up time. Due to the need-based melting both the energy requirement and the adhesive consumption are greatly reduced. The systems called "tankless" systems achieve the required

Melting performance through a grille installed in the (small) tank, increasing the surface area over which heat is supplied within the (small) tank. In known devices, the grid is firmly installed inside the (small) tank. A cleaning of the system is made difficult or only limited possible.

Since the hot glue supply is no longer done manually, but automatically from a large-volume reservoir, overfilling or spilling is excluded. This also minimizes the risk of burns for the operating personnel. In addition, the uninterrupted production means an extraordinary saving of time. Another major advantage of the extremely compact "tankless" device technology is the closed nature of the system, so that the glue used does not have any

Is exposed to environmental influences. Contaminations or coking, at

Tank melters are unavoidable, are hardly present here and minimized even with difficult adhesives. In particular, due to the shorter service life of the glue at high temperatures cracking is significantly reduced and thereby negative consequential damage such as nozzle clogging and material damage largely avoided.

The object of the invention is to further optimize the tankless hot melt systems and in particular to make them more flexible, so that such a system can be used without problems for different production conditions, for example with different adhesives.

The above object is achieved by a heating system comprising the features of claim 1. The above object is further achieved by a

Packaging device and a method for adjusting a heating system, comprising the features of claims 1 1 and 13, respectively. Further advantageous embodiments are described by the respective dependent claims. The invention relates to a heating system for an adhesive agent of a packaging device, in particular for melting an adhesive for a packaging device for producing cardboard packaging. The

Cardboard packaging is used in particular to combine product groups that have been put together into containers or packaging units to form sales units. The article composition can be arranged completely within the cardboard packaging. The cardboard packaging is then preferably glued, so that the articles are securely arranged within the carton and summarized. In this case, adhesive dots or splices are applied to the cardboard packaging, which serve the bonding of areas of the cardboard packaging to this in a defined

To fix the shape. For example, the carton packaging can also be a tray on which the article composition is arranged. Preferably, the tray has lateral overlapping surfaces which extend over the base of the

Outstanding article compilation. These lateral overlapping surfaces are folded upwards and at least partially fixed to one another by means of an adhesive or adhesive. The tray thus forms a secure footing with lateral

Limitation for article compilation. As a rule, the articles arranged on the tray are then wrapped with a shrink film. By heating the shrink film in a shrinking device, a compact shrink wrap is produced. In particular, the packaging device may comprise a plurality of folding means comprising adhesive-containing packaging material tabs

Contact carton packaging and fold. In particular, according to a further embodiment, it may be provided that adhesive is first applied at defined locations to a still unfolded cardboard, which is subsequently folded and glued accordingly.

The heating system according to the invention comprises a feed system for a

unmelted adhesive, such as a glue granules and a

Storage device for tempered and / or tempered, molten adhesive with a heater for melting and / or for temperature control of the adhesive. The storage device further comprises at least one

Connection means for a in or on, in particular within, the storage device additionally optionally mountable heating means for melting and / or for

Tempering of the adhesive.

In particular, the optionally mountable heating means is supplied with power via the at least one connection means, ie the heating means preferably does not have its own Power supply, but is connected to the power supply of the heating system, in particular to the power supply of the storage device.

In particular, the supply system of the heating system comprises - similar to known so-called "tankless" systems - a large-volume storage container for an unmelted adhesive from which preferably granulated adhesive agent is fed to the storage device via an automatic filling system. or is melted and / or tempered by the optional heating means additionally mounted in and / or on the storage device

Heating insert formed and at least partially disposed within the storage device for molten and / or tempered adhesive and connected via at least one connection means releasably connected to the storage device. The heating insert can be quickly and easily separated from the storage device, whereby a cleaning of the heating insert and / or storage device compared to known "tankless" systems with firmly installed heater significantly easier and also a time and cost efficient cleaning is possible or the heating means molten and / or tempered adhesive is cached in the storage device of the heating system until it is removed and used within the packaging device The storage device corresponds - also comparable to known "tankless" systems - a small tank in which only one actually required Processing temperature tempered amount of adhesive is cached. In particular, by the automatic filling and continuous granulation by the feed system, the level in the

Storage device always kept largely at a predefined level.

Depending on the requirements of the particular packaging device, the heating system is used with or without a suitable heating element. If a higher heating power or melting capacity is necessary, a suitable heating element is selected and solvable on or via the connection means in or on the

Storage device arranged and / or fixed. Depending on

Adhesive requirements of the packaging device will be different

Heating power or melting power needed to provide the appropriate amount of molten and / or tempered adhesive. The required heating power or melting capacity can continue depending on the used Adhesive, be different from the required throughput and / or depending on other process conditions.

The heating means, for example, by a grid-like heater or the like. educated. According to a preferred embodiment of the invention, the

Heating system at least two in their heating capacity and / or melting capacity

Depending on the adhesive requirement of the packaging device, a suitable heating insert is selected and arranged on or via the connection means releasably in or on the storage device of the heating system and / or attached. Especially at low throughput rates can

Melting and / or tempering of the adhesive by the heating system also take place exclusively by means of the heater of the memory device, i. the heating system is used without a heating element or the electrical supply of the heating element is switched off. The heating device of the storage device is also referred to below as the base heating device.

The different heating power and / or melting power of the different heating inserts is particularly due to their respective total outer surface. According to a preferred embodiment, provision is made for a first heating insert to have a first overall outer surface, and for a second heating insert to have a second deviating overall outer surface. For example, the first heating element has a higher total outer surface than the second heating element. When using the heating system with the first heating insert thus larger throughputs can be achieved than when using the heating system with the second heating element or without

Heating insert, since with the first heating insert per defined time unit larger amounts of adhesive can be melted and / or tempered.

Preferably, the heating system comprises a plurality of different heating inserts, each with different total outer surfaces. The different total outer surfaces arise, for example, due to different thicknesses of the heating inserts and / or due to different shape, screening or the like. The heating inserts may have different shapes, for example a first heating element may take the form of a grid with square subunits or the like.

have a second heating element, an annular heating coil o.ä. include, a third heating element may consist of a plurality of at least substantially parallel heating elements exist, which are optionally connected to each other via a crossbar, etc. For the expert further embodiments are conceivable, which have a different total outer surface due to their shape.

According to one embodiment of the invention, the at least one

Connection means of the memory device at least one electrical contact element. Furthermore, the at least one heating means has at least one connection means with a correspondingly formed electrical contact element. Between the electrical contact element of the storage device and the electrical

Contact element of the heating means can be made an electrical connection, in particular a detachable electrical connection. Preferably, this has

Connecting means of the memory device at least one electrical contact and a correspondingly formed connection means of the heating means has at least one correspondingly formed counter contact. In particular, the electrical connection can be established by connecting the at least one connection means of the storage device to the at least one connection means of the heating means.

According to one embodiment of the invention, the arrangement of the at least one connection means of the storage device corresponds to the arrangement of the at least one connection means of the heating means that this can be mounted only in a defined position within the storage device.

Preferably, the arrangement corresponds to the at least one electrical

Contact element of the heating means with the arrangement of the at least one electrical contact element of the storage device. For example, the corresponding electrical contact elements are designed as connecting parts of a plug connection, wherein the connecting parts are aligned by positive locking fit and in particular can be releasably fixed to each other in a non-positive manner, wherein the electrical connection is made. Optionally, alternatively or additionally, a releasable mechanical locking can be provided.

According to a further embodiment of the invention, the

Storage device of the heating system at least one locking element and the heating means has at least one correspondingly formed locking element, wherein the heating means by a locking between the at least one locking element of the storage device and the at least one Locking element of the heating means can be releasably fixed in or on the storage device.

Particularly preferred are the above-described connection means of

Storage device and heating means simultaneously formed as electrical contact elements as well as locking elements, so that both an electrical connection between the heating means and the storage device and a releasable locking between the heating means and the storage device can be produced by the connection means.

For example, the heating means has at least one plug and the

Storage device at least one socket. By plugging the plug of the heating medium into the socket of the storage device is the electrical

Established connection and the heating means preferably set in the correct orientation in or on the storage device. Analog is conceivable that the heating means are equipped with a socket and the memory device with a correspondingly arranged connector.

Furthermore, it can be provided that for mounting the heating means within the storage device at least two connection means within the

Storage device and are provided on the heating means. The connection means can either be of the same design or differ from one another, but it is always important that there is a corresponding connection means on the heating means for a connection means of the storage device. For example, it can be provided that for the production of the electrical connection at least two connection means with electrical contact elements to the heating means and

are provided corresponding to the memory device. Here, the

Arrangement of the connection means or the contact elements be chosen such that the heating means can be arranged only in a defined arrangement and / or orientation in or on the storage device, whereby a faulty installation of the heating means in or on the storage device of the heating system can be effectively prevented. For example, it can be provided that the heating means two

Includes connecting means with different electrical contact elements and that the memory device has two corresponding connection means with different electrical contact elements. In this case, there is only one possible

Installation position of the heating means in or on the storage device. A faulty installation of the heating medium is therefore not possible. The contact elements are formed and / or surrounded by protective elements that, when establishing the electrical connection between the

Storage device and the heating means, the contact elements are preferably connected to each other such that the resulting electrical connection is protected in itself from direct contact with the adhesive.

According to a preferred embodiment of the invention, the

The base heating device of the storage device is formed in particular by heatable side walls and / or heatable bottom plate of the storage device. The storage device is designed, for example, as a small, in particular open-top, tank and forms the base heating device, as is known from traditional hot glue systems.

The adhesives melted and / or tempered via the heating means and / or the base heating device are stored in the storage device of the heating system until they are removed and used within the packaging device

cached. There are known applications in which the adhesive under

Use of a heating insert and using the base heating of the heating system is melted and / or tempered. Continue to be

Possible applications in which when using a heating element, the base heater of the heating system is turned off and not used.

In particular, it is provided that the electrical supply of the heating means and the base heater is independent of each other and that the heating means and the base heater are each individually adjustable. Thus, the heating system can continue to be used, for example, in the event of a defect of the base heater by selecting a suitable heating element. A defect in one

Conventional hot glue system would stop the production

Effect packaging device. The production of the packaging device could only be continued after repair or replacement of the hot glue system. In the hot glue system according to the invention, a defect of the base heater by Use of a heating insert with a higher heat output or melting capacity are at least temporarily compensated. The replacement of the heater requires only a fraction of the time that would be necessary for troubleshooting and repair. The repair can thus be delayed in the heating system according to the invention, for example, until a normal in the normal production process

Production stop is provided.

Furthermore, it is possible to use the heating system by the

Adhesion agent is melted and / or tempered only by means of the base heater. In this case, the heating means is preferably completely removed, whereby the cleaning is significantly simplified following a production process.

The heating power or melting capacity of the heating system can thus in a format change and / or a product change and / or a change of

Adhesive used by replacing the heating insert quickly and easily adapted to the changed system requirements. For example, during a format and / or product change, a changed throughput of adhesive per hour may result, so that a changed heating or melting performance is necessary. The use of another adhesive may, for example, be other

Temperatures for melting and / or tempering of the adhesive condition. If, for example, at low flow rates required, a melting and / or tempering of the adhesive takes place exclusively by means of the base heater, it is preferably provided that the electrical

Contact elements of the storage device by means of suitable protective caps or the like.

can be covered in order to avoid a direct contact with the electrical contact elements of the memory device with the adhesive, as this could lead to damage and / or contamination of the electrical contact elements of the memory device. In particular, the at least one connection means is designed in the region of the at least one electrical contact element or can be covered in regions or the like, that the electrical contact element is protected. According to a preferred embodiment of the invention, the

Inner surfaces of the storage device, in particular the upwardly facing inner bottom surface and the inner side surfaces, with an anti-adhesive coating so that the adhesive preferably does not adhere to the storage device, thereby facilitating the cleaning of the heating system.

The invention further relates to a packaging device for articles or article assemblies, wherein the articles or article compositions are summarized by a cardboard packaging. In the production of the cardboard packaging by the packaging device, at least parts of the cardboard packaging are joined together by application of an adhesive. The adhesive is provided by a heating system, in particular a heating system with the features described above. Furthermore, in the context of the present invention, a method for

Adapting a heating system for an adhesive of a packaging device to the respective production requirements described. The heating system comprises a heating means which, if necessary, can be combined with a base heater of the storage device and / or replaced by another embodiment of the heating means. The base heating device is formed in particular within a storage device for temperature-controlled and / or tempered, molten adhesive and is formed for example by heatable side walls of the storage device. The heating means for melting and / or for

Tempering of the adhesive is designed in particular as a heating insert, as has already been described in detail above. The heating means is mounted depending on the adhesive requirement of the packaging device on or via the at least one connection means of the storage device within the same.

According to a preferred embodiment, a controller may be provided, with which the heating system and possibly also the packaging device is / are operated. In particular, the control can be used to coordinate the heating system and the packaging device.

For example, by the controller, the amount of adhesive to be replenished, i.a. per unit of time, and / or the amount dispensed, i.a. per unit of time or per carton or per shot, of molten

Adhesives are controlled. It is even conceivable that a control is stored in the control, which regulates one or both of these quantities. The

Input variables of this regulation can be a level of molten

Adhesion agent, a measured discharge amount, a machine speed (ua be processed articles or cartons per unit time) and / or a level of non-melted adhesive. Corresponding to these input variables, suitable sensors, for example level sensors, weight sensors, cameras with image evaluation or the like, can be placed on the heating system and possibly on the packaging device.

The processing speed can be input, for example, from an operator to the controller via a suitable input device. A processing stop (machine stop) is also detected immediately and flows into the controller. The method may alternatively or in addition to the features described one or more features and / or properties of the previously described

Heating system and / or the previously described packaging device.

Likewise, the heating system and / or the packaging device may alternatively or additionally comprise one or more features and / or properties of the described method.

With the heating system according to the invention, the packaging device and / or the method, depending on the use of a heating insert per unit time different amounts of adhesive can be processed. The

Heating system can in particular by removing or replacing the heating insert quickly and easily to different flow rates or to changed

Be adjusted when using a different adhesive. In particular, thus a major drawback of conventional tank systems is eliminated, which must be completely replaced if the tank size is incorrectly designed.

Instead, the heating system according to the invention can be easily adapted by selecting a suitable heating insert, without a complete replacement is required. In addition, the heating system, the packaging device and the method described allows a great flexibility in a product change, as the

Heating power or melting power can always be adjusted to the actual consumption. The optimal design of the heating capacity or melting rate has a positive effect on the energy costs. By simply removing the heating inserts, the cleaning of the respective heating element and / or the storage device in the form of a (small) storage tank is significantly simplified and can also be performed faster. For the producer or user of the invention, there is a particular advantage that complaint costs are reduced due to a wrong calculation of the tank size, since now no longer the whole system must be replaced. Instead, the customer is supplied with a new suitable heating insert, which is then releasably secured in or on the storage device or in or on the storage tank of the heating system.

Furthermore, the producer can reduce his number of variants of different devices. He no longer has to provide different tank sizes, instead he only needs different suitable heating inserts to adapt a basic unit for different purposes, which in particular greatly reduces the storage of the equipment and / or spare parts.

For the customer or user, there is the advantage that the heating system can be used in combination with various packaging devices, wherein it is not determined to a specific adhesive requirement, since the heating system can be easily upgraded.

Hereinafter, embodiments illustrate the invention and its advantages with reference to the accompanying drawings. 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.

According to a preferred embodiment, the side walls 31 and / or the bottom region 32 of the storage device 21 are heatable and thus serve as the base heating device 30 for melting and / or tempering the adhesive raw product ARP within the storage device 21.

The feed system 19 comprises, in particular, a storage or magazine 20 for the raw adhesive agent product ARP and an automatic filling system 22. The adhesive agent raw product ARP is in particular conveyed via the automatic

Filling system 22 metered the heating means 25 and / or the base heater 30 and the memory device 21 fed. The automatic filling system 22 may comprise, for example, a controlled valve 23, which is coupled to a control device 24, in particular to the machine control of the packaging device 1 (see FIG. 1), and due to process parameters stored in the control device 24, the adhesive raw product ARP in corresponding dosage emits.

To minimize the cleaning effort of the heating system 15. According to another

Embodiment of the invention, the raw adhesive agent ARP can also be melted and / or tempered solely by the heating means 25, for example, in a defect of the base heater 30. In Fig. 3 and in Figures 4 to 6, the feed system 20 for the

Adhesion agent crude product ARP not shown. Fig. 3 shows the heating system 15 without a releasable heating element (reference numeral 26 in Fig. 2). On the other hand, FIGS. 4 to 6 each show an illustration of a heating system 15 according to the invention

different heating inserts 26a, 26b, 26c from above. In FIG. 3, two are arranged within the memory device 21

To detect connection means 34. The connection means 34 each comprise electrical contact elements 35 The heating means 25a, 25b, 25c in the form of heating inserts 26a, 26b, 26c shown in FIGS. 4 to 6 have connection means 39. These also include electrical contact elements 40. Between the electrical contact elements 35 of the memory device 21 and the electrical contact elements 40 of

Heating inserts 26a, 26b, 26c, an electrical connection 45, in particular a releasable electrical connection 46 can be made.

So that the electrical connection 45 can be produced quickly, easily and reliably, the arrangement of the connection means 34 and thus the arrangement of the electrical contact elements 35 of the memory device 21 preferably corresponds to the arrangement of the connection means 39 and thus the arrangement of the electrical contact elements 40 of the heating means 25 , 25a, 25b, 25c. According to one

Embodiment of the invention are the electrical contact elements 35, 40 as Formed connecting parts of a plug connection, wherein the connecting parts are aligned to form the electrical connection 45 by positive engagement and are in particular fixed non-positively releasably to each other. In this case, the electrical contact elements 35, 40 simultaneously assume the function of locking elements 36, 41. Reference numeral 36 denotes in this case

Locking element of the memory device 21 and reference numeral 41 designates in this case the locking element of the heating means 25, 25a, 25b, 25c.

The arrangement of the connection means 34, 39 on the respective heating means 25, 25a, 25b, 25c and the storage device 21 determine the arrangement and / or orientation of the heating means 25, 25a, 25b, 25c within the storage means 21 so that they always automatically correct in the Heating system 15 is installed

FIGS. 3 to 6 in particular demonstrate that the heating power or

Melting power of the heating system 15 quickly, easily and inexpensively to the

Process conditions can be adjusted because the heating system 15 can optionally be used with different heating inserts 26 a, 26 b, 26 c or without additional heating element 26. Depending on the required heating power and / or melting capacity, the suitable heating insert 26a, 26b, 26c is selected and arranged detachably in or on the storage device 21. Alternatively, the heating system 15 can also be operated without a heating insert 26. The arrangement of the different heating inserts 26a, 26b, 26c in or on the storage device 21, which is preferably particularly simple and quick to be removed via the connection means 34, 39, allows rapid adaptation of the heating system 15, for example, during a product change, a change in the one used

Adhesion agent, etc. Also, this is due to incorrect calculation of per defined time unit amount of adhesive required a quick correction possible without the entire heating system 15 must be replaced.

The different heating inserts 26a, 26b, 26c differ in their heating power due to their different shape and / or material thickness. The heating power is particularly dependent on the size of the total outer surface AF26a, AF26b or AF26C of the heating inserts 26a, 26b or 26c. In this case, the greater the total outer surface AF26a, AF26b, AF26C of the respective heating insert 26a, 26b, 26c installed in the heating system 15, the higher the heating power or melting power. In the embodiments 15, 15a, 15b, 15c shown in FIGS. 3 to 6, the following applies for the heating power or melting power H: H15 (FIG. 3) <Hi5c (FIG. 6) <Hisa (FIG. 4) <Hisb (FIG. Figure 5). If the heating system 15 is used without a heating insert 26, so that the melting and / or tempering of the adhesive takes place exclusively via the base heater 30 of the memory device 21, then it is preferably provided that the electrical contact elements 35 of the memory device 21 from contact with the Adhesion agent are protected. For example, the electrical

Contact elements 35 of the memory device 21 by means of suitable protective caps or the like. covered.
