Description

Technical Field

[0001] The utility model relates to a coupling system, a gluing machine, a label device for a beverage container and a packaging machine for the beverage container. Background Art

[0002] When handling articles such as beverage containers, a gluing device is used in practice, which can be glued by a suitable gluing head so that fixation can be provided by gluing. From the corresponding gluing device, glue is delivered to the corresponding gluing head by a corresponding hose connection.

[0003] A gluing device which is able to supply a gluing head with cold glue via a suitably designed hose connection is known from the German utility model DE 20 2014 100 123 U1. This well-known gluing device is designed as a rotary slide pump for gluing. The rotary slide pump comprises a rotor with at least two crossed slides. In addition, a stator is provided, the effective cross section of which deviates from a circular shape, so that, regardless of the rotary bearing of the rotor, the play of the slides in the displacement direction does not exceed 2 mm.

[0004] In the case of a machine using such a gluing device comprising a plurality of different gluing format components, such a gluing format component can be fluidically coupled to the gluing device by means of a corresponding fixed hose connection. In practice, the number of connections of a gluing device is limited, so that when a machine comprises a plurality of different gluing format components, a plurality of gluing devices are usually required.

[0005] The corresponding hoses and the multiple different gluing devices required to supply multiple different glue-format components require a high amount of space, which is often not available. Utility Model Content

[0006] Therefore, one object of the invention may be seen as providing a method by which the problems described may be at least partially avoided.

[0007] The utility model relates to a coupling system for fluidly connecting glue-coating tubes. The coupling system comprises a housing, and at least one coupling piece which can be fixed on the glue-coating tube of a glue-coating device, which is accommodated by the housing and can be selectively detachably coupled with the reverse coupling pieces of a plurality of additional glue-coating tubes of different glue-coating format components, so that a fluid connection is constructed between a corresponding glue-coating tube of the glue-coating device and a corresponding additional glue-coating tube of a corresponding glue-coating format component through the coupling piece and the reverse coupling piece coupled to the coupling piece.

[0008] Therefore, in practice, multiple additional glue coating tubes of multiple different glue coating format components can be selectively and detachably coupled in sequence on a specific coupling member of the coupling system through corresponding anti-coupling members, so that a fluid connection is constructed between the corresponding glue coating tube (or glue supply tube) of the gluing device and the corresponding additional glue coating tube of the corresponding glue coating format component through the coupling member and the anti-coupling member coupled to the coupling member.

[0009] Therefore, it is no longer necessary to provide a plurality of gluing devices for supplying glue to a plurality of different gluing formats. By means of the coupling system, when different gluing formats are required for gluing, it is possible to switch between a plurality of different gluing formats in a simple and uncomplicated manner. By means of the coupling system, a gluing machine can be designed in a cost-effective and space-saving manner.

[0010] In some possible embodiments, at least one coupling member is configured as a coupling body, wherein a corresponding counter-coupling member configured as a plug can be inserted therein for corresponding coupling. Such an embodiment allows a quick and simple connection between the corresponding coupling member and the corresponding counter-coupling member. It is conceivable here that at least one coupling member includes an actuating sleeve, which is axially movably mounted on the coupling body to release the coupling formed between the at least one coupling member and the counter-coupling member.

[0011] In various embodiments, the actuating sleeve can accommodate the coupling body at least in some areas, or the actuating sleeve can run radially around the coupling body.

[0012] Alternatively or additionally, at least one coupling member may include a plurality of locking balls, and when the corresponding counter-coupling member configured as a plug is inserted into the coupling body, the counter-coupling member configured as a plug is independently locked on the coupling body by these locking balls. If at least one coupling member also includes the above-mentioned actuating sleeve, at least one coupling member can be configured so that the locking configured by the plurality of locking balls can be released by moving the actuating sleeve in the axial direction.

[0013] In the described embodiments, or in general, at least one coupling element can be configured such that the at least one coupling element automatically locks with a corresponding counter-coupling element configured as a plug when inserted into the coupling body.

[0014] It may also be that the coupling system comprises at least one heating element for regulating the temperature of at least one coupling part, wherein the at least one heating element is accommodated in the housing. The at least one heating element may be at least one heating cartridge. Alternatively or additionally, the at least one heating element may be formed by at least one electrically operable heating element. Thus, in various embodiments, the glue may be heated by the at least one coupling part and leave the coupling system in the form of hot glue. The actual temperature of the hot glue leaving the coupling system may be in a temperature range of about 130°C to about 190°C.

[0015] The housing can be formed by at least two corresponding parts, which can accommodate at least one coupling member inaccessibly from the outside when the at least two corresponding parts are engaged. In addition, the at least two corresponding parts can be separated, so that the at least one coupling member can be accessed by separating the at least two corresponding parts, or the user can access the at least one coupling member by separating the at least two corresponding parts.

[0016] Alternatively or additionally, the coupling system may include a closing mechanism for locking when the at least two corresponding parts are engaged. The closing mechanism is operable to release the lock. In some feasible embodiments, the closing mechanism is a bolt cylinder unit. The bolt cylinder unit can be mounted on the housing or on one of the at least two corresponding parts of the housing.

[0017] The utility model also relates to a gluing machine, which can be particularly and preferably configured to execute the implementation of the method to be described below.

[0018] The gluing machine of the utility model comprises at least one gluing device with at least one gluing tube. In addition, the gluing machine has a plurality of gluing format components with a corresponding additional gluing tube, which are configured as a plurality of gluing format components for gluing containers and / or container packaging. The plurality of gluing format components can be gluing heads, which can apply glue to the container and / or container packaging by spraying glue on the container and / or the packaging.

[0019] In addition, the plurality of glue application format components may be a plurality of glue rollers, which may apply glue to the container and / or container packaging by rotating the plurality of glue rollers and contacting the container and / or packaging surface.

[0020] A gluing machine is provided, comprising at least one coupling system having a housing and at least one coupling, the coupling system accommodating the at least one coupling via the housing and being fluidically connected to at least one gluing hose of at least one gluing device. The coupling system can be formed separately according to the previously described embodiments without having to refer to the previously described embodiments again.

[0021] The plurality of additional glue-coating tubes of the plurality of glue-coating format components respectively include anti-coupling pieces. At least one coupling piece can be selectively detachably coupled with the anti-coupling piece of the additional glue-coating tube, so that a fluid connection is constructed between the corresponding glue-coating tube of the glue-coating device and the corresponding additional glue-coating tube of the corresponding glue-coating format component through the coupling piece and the anti-coupling piece coupled to the coupling piece.

[0022] In the gluing machine, at least one coupling piece may be configured as a coupling body, and a corresponding counter-coupling piece configured as a plug may be inserted into the coupling body to perform corresponding coupling with the coupling body.

[0023] This has also been demonstrated in gluing machines, where at least one coupling element is designed in such a way that, when inserted into the coupling body, the at least one coupling element automatically locks into a corresponding counter-coupling element designed as a plug.

[0024] Furthermore, the coupling system can include at least one heating element for temperature control of at least one coupling part, wherein the at least one heating element is accommodated in a housing of the coupling system. The at least one heating element can be at least one heating cartridge.

[0025] Furthermore, in this embodiment, the gluing machine has a closing mechanism for locking the housing. The closing mechanism of the gluing machine may also be a bolt cylinder unit.

[0026] The gluing machine may comprise at least one temperature sensor for detecting an actual temperature of at least one coupling member, wherein the at least one temperature sensor and the closing mechanism are operatively connected to one another such that when the corresponding actual temperature detected by the temperature sensor is higher than a predetermined target temperature, release of the lock established by the closing mechanism is prevented.

[0027] The gluing machine may further comprise a control device, which is connected to the at least one temperature sensor and the closing mechanism, respectively, and is capable of identifying or detecting a corresponding actual temperature of the at least one coupling member by the at least one temperature sensor. The control device may store information about a predetermined target temperature. Furthermore, the control device may be configured such that when the corresponding actual temperature detected or identified by the at least one temperature sensor is higher than the predetermined target temperature, the release of the lock established by the closing mechanism is prevented.

[0028] In the gluing machine, the coupling system can be arranged in a defined safety area of ​​the gluing machine and comprises at least one safety sensor, by which the presence of a person in the safety area can be detected. The at least one safety sensor and the gluing device can be operatively connected to each other so that when the presence of a person in the safety area is detected by the at least one safety sensor, gluing by the gluing device is prevented.

[0029] A control device connected to the at least one safety sensor and the gluing device may be provided. The control device may be configured such that gluing by the gluing device is independently blocked when the control device recognizes the presence of a person in the safety area via the at least one safety sensor. The at least one safety sensor may be, for example, a camera whose detection area extends into the safety area. The at least one safety sensor may also be a touch sensor that recognizes the opening of a door, which allows a person to enter the safety area.

Furthermore, in the method, a plurality of different gluing format components are provided, each of which has an additional hose connection with a corresponding counter-coupling, wherein the coupling components can be selectively and detachably coupled to the corresponding counter-coupling components, so that a fluid connection is configured between the corresponding gluing tube of the gluing device and the corresponding additional gluing tube of the corresponding gluing format component via the coupling and the counter-coupling coupled to the coupling.

[0033] The method includes at least the following steps, but should not be considered final:

[0035] - Connect the coupling piece to the counter-coupling piece that connects the additional glue tube of the selected glue format component, whereby a fluid connection is constructed between the corresponding glue tube of the glue application device and the corresponding additional glue tube of the selected glue format component via the coupling piece and the counter-coupling piece coupled to the coupling piece.

[0036] In various embodiments, the coupling system can have a closing mechanism by which the housing is locked. In addition, the corresponding actual temperature of the coupling body can be detected by a temperature sensor, wherein the temperature sensor and the lock interact so that the lock is maintained when the actual temperature is higher than a predetermined target temperature.

[0037] The method can be realized or performed using one of the previously described embodiments of the gluing machine according to the invention.

[0038] Here, it is additionally emphasized that the features previously described in the embodiment of the coupling system according to the utility model also relate to or can be part of the method and the gluing machine according to the utility model.

[0046] The same reference numerals are used for the same or the same effect elements of the present invention. In addition, for the sake of clarity, only the reference numerals necessary for the description of the corresponding figure are depicted in a single figure. The embodiments shown are merely examples of the design scheme of the present invention and do not represent conclusive limitations.

[0047] Figure 1 A schematic perspective view of an embodiment of a coupling system 1 according to the invention is shown and steps which may be provided in various embodiments of the method are explained.

[0048] In order to apply glue to the glue-coating format components 74 and 76 (see Figure 5 ) glue supply, in the device known in the prior art, the corresponding glue application format components 74 and 76 are firmly connected to the glue application device 72 through a hose connection.

[0049] According to each gluing process, different gluing format components 74 or 76, or different nozzles, may be required, which are suitable for each gluing process and are supplied with glue according to the gluing process through the gluing device 72. For this reason, in practice, a plurality of gluing devices 72 that are firmly connected to a plurality of different nozzles are usually provided so that switching between different nozzles can be possible.

[0050] A gluing machine comprising a plurality of gluing devices 72 for supplying glue to various nozzles has a high space requirement. Figures 1 to 4 The embodiments shown and described in Figure 5 As shown as part of a packaging machine 50, when different spray heads are used for different gluing operations, the space requirement is smaller. In addition, a smaller number of gluing devices 72 are required, so that by coupling system 1, an economically advantageous embodiment of the gluing machine 70 can also be provided.

[0051] Through the coupling system 1, the glue pipes 5 and 5' can be fluidically connected to the additional glue pipes 15 and 15'. The glue pipes 15 and 15' lead from the coupling system 1 to the glue application device 72 (see Figure 5 ) and a glue pump, and are firmly connected to the glue device 72 and the glue pump, respectively. Such a glue device can have multiple outlets for glue, so that glue can be pumped through the two glue pipes 15 and 15' through the common glue device 72 or the common glue pump, respectively. At present, the two glue pipes 15 and 15' are fluidically connected to the common glue device 72 or the common glue pump, respectively.

[0052] Additional glue pipes 5 and 5' lead from the coupling system 1 to the glue format components 74 and 76 respectively (see Figure 5 ), for clarity, in Figures 1 to 4 For example, the glue format component can be a nozzle of a labeling device. Each nozzle or each glue format component is assigned a separate additional glue tube 5 or 5', through which glue is supplied to each nozzle or glue format component.

[0053] In order to establish a fluid connection between the glue pipes 15 and 15' and the additional glue pipes 5 and 5', the coupling system 1 includes two couplings 6 and 6', which are formed as coupling bodies 7 and 7'. In the end region, the glue pipes 15 and 15' leading from the glue device 72 or the glue pump to the coupling system 1 are provided with counter-couplings 18 and 18', which are respectively configured as plugs 19 and 19'.

[0054] The counter-coupling 18 or 18' is inserted into the coupling 6 or 6' so that the respective counter-coupling 18 or 18' is firmly connected to the respective coupling 6 or 6'. The respective coupling 6 or 6' comprises a plurality of locking balls which automatically lock the respective counter-coupling 18 and 18' to the coupling 6 or 6' when the respective counter-coupling 18 and 18' is inserted into the coupling 6 or 6'.

[0055] In addition, a counter-coupling 8 or 8', which is respectively configured as a plug 9 or 9', is fixed to the end of the additional glue coating pipe 5 or 5' leading from each spray head to the coupling system 1. Similarly, the counter-coupling 8 or 8' is inserted into the coupling 6, so that the corresponding counter-coupling 8 or 8' is firmly connected to the corresponding coupling 6 or 6'.

[0056] When the anti-couplings 18 and 18' fixed on the glue-coating tubes 15 and 15' and the anti-couplings 8 and 8' fixed on the additional glue-coating tubes 5 and 5' are inserted into the coupling bodies 6 and 6', the glue-coating tubes 15 and 15' are fluidly connected with the additional glue-coating tubes 5 and 5'. Therefore, the glue can be transported from the glue-coating tubes 15 and 15' to the additional glue-coating tubes 5 and 5' through the couplings 6 or 6' and the anti-couplings 8 or 8' or 18 and 18', respectively.

[0057] Each glue tube 15 and 15' and each additional glue tube 5 and 5' is assigned a heating port 23 and 23' or 25 and 25'. By means of electrical contact with the heating ports 23 and 23' or 25 and 25', respectively, the heating elements can be supplied with electrical energy, wherein appropriate electrical lines can be passed through the respective glue tubes 5 and 5' or 15 and 15', if necessary. By means of the respective heating elements, the glue can be heated to a temperature such that the glue is transported in the form of hot glue in the additional glue tubes 5 and 5'. For this purpose, the couplings 6 and 6' are heated by the heating elements.

[0058] The coupling system 1 comprises a housing 40 formed of two parts 42 and 44. Figure 3 and Figure 4 As shown, when the two parts 42 and 44 are joined, the above-mentioned heating element can be arranged inaccessibly from the outside in the housing 40. Similarly, when the two parts 42 and 44 are joined, the couplings 6 and 6' are arranged inaccessibly from the outside in the housing 40. Advantageously, this can exclude the risk of the heating element or the heated couplings 6 and 6' being accidentally touched by the user, which could harm the user.

[0059] The first part 42 of the housing 40 comprises two openings 32 and 32' and two slots 14 and 14'. When the two parts 42 and 44 are joined and the housing 40 is closed, the projections 12 and 12' of the second part 44 are inserted through the slots 14 and 14'. In addition, a tab 26 of the side housing wall 13 of the first part 42 is inserted into a notch 16 of the second part 44. The closure of the housing 42 or the fixing of the two parts 42 and 44 to each other is achieved by Figure 2 The closure mechanism 60 is shown and will be described below.

[0060] When the two parts 42 and 44 are joined, the retaining rings 34 and 34' are also positioned in the openings 32 and 32' of the first part 42. The retaining rings 34 and 34' are part of the anti-couplings 18 and 18' fixed to the rubber tubes 15 and 15'. When the retaining rings 34 and 34' are located in the openings 32 and 32' of the first part 42, the anti-couplings 18 and 18' are also retained in the first part 42 by the retaining rings 34 and 34'.

[0061] Via the couplings 6 and 6', a plurality of counter-couplings 8 and 8' can be selectively connected, which lead to the spray heads of the labeling device via the additional hose connections 5 and 5'. If a spray head that was not previously required is to be switched to, the counter-coupling 8 or 8' provided on the additional hose connection 5 or 5' of the spray head that is now required is inserted into the coupling 6 or 6'. Thus, a single gluing device 72 can supply glue to a plurality of different spray heads, for which a fluid connection can be selectively established between the individual spray heads and the gluing device 72 via the coupling system 1.

[0062] The counter-couplings 8 and 8' are plugs 9 and 9' which are automatically locked on the corresponding couplings 6 or 6' when the plugs 9 and 9' are respectively inserted into the corresponding couplings 6 or 6'. When the corresponding locking is released, the corresponding counter-coupling 8 or 8' together with the corresponding additional glue-applying tube 5 or 5' and the spray head fixed thereon can be removed from the corresponding coupling 6 or 6' and provided for maintenance or transferred to a bearing or storage unit.

[0063] As mentioned above, the coupling 6 or 6' with the high temperature for heating the glue is accommodated inaccessibly from the outside by the housing 40. To further reduce the risk of injury, even though the connection points of the coupling 6 or 6' can be accessed from the outside for inserting the plug 9 and 9', respectively, they also have thermal insulation properties.

[0064] In accordance with Figures 1 to 4 In the embodiment of the present invention, the coupling system 1 comprises exactly two coupling members 6 or 6'. However, it is also conceivable that the coupling system 1 in various embodiments comprises exactly such coupling members 6 or 6', or that the coupling system 1 in various embodiments comprises more than two coupling members 6 or 6'.

[0065] It can also be Figure 1 The glue-applying tubes 15 and 15' shown and / or Figure 1 The additional glue tubes 5 and 5 ′ shown have different cross-sectional diameters.

[0066] If the coupling system 1 forms part of a gluing machine 70 (see Figure 5 ), the gluing machine 70 can completely include such a coupling system 1. The gluing machine 70 can also include a plurality of such coupling systems 1.

[0067] Figure 2 Shown according to Figure 1 The embodiment of the coupling system 1 is disclosed, and other aspects are described. Figure 2 In particular, it can be seen that the closing mechanism 60 that can lock the first part 42 and the second part 44 when the first part 42 and the second part 44 are engaged, such as Figure 3 and 4 As shown. Figure 2 , the first portion 42 and the second portion 44 are still separated from each other.

[0068] In the embodiment shown, the closing mechanism 60 is formed as a bolt-cylinder unit 62 and is connected to a control device S which is able to operate the closing mechanism 60 to lock the two parts 42 and 44. When the first part 42 and the second part 44 are engaged and the housing 40 is closed, the coupling 6 or 6 ', the already described heating element and the temperature sensor are arranged in the housing 40. By means of the temperature sensor, the control device S can detect the respective actual temperature of the coupling 6 or 6 '.

[0069] Only when the respectively detected actual temperature is within the predetermined target temperature, the closing mechanism 60 is opened by the control device S. This can exclude the possibility of accidental contact of the coupling 6 or 6' when the temperature is high. Therefore, there is no risk of injury, because the control device S can detect the respective actual temperature of the coupling 6 or 6' by the temperature sensor and trigger the release to open the housing 40 by the closing mechanism 60 only when the detected respective actual temperature is within the predetermined target temperature.

[0070] May include Figures 1 to 4 Embodiment of the coupling system 1 of the gluing machine 70 (see Figure 5 ) usually has other sensors connected to the control device S and used for safety-related purposes. Thus, the gluing machine 70 can include at least one safety sensor, which can detect whether a person is in a safety area in which the coupling system 1 is also arranged. The gluing device 72 or the gluing pump of the gluing machine 70 can be connected to the control device S.

[0071] If the control device S detects the presence of a person in the safety area by means of such a safety sensor, the control device S can automatically switch the glue application device 72 without pressure, so that glue is not pumped into the coupling system 1 through the glue application pipe 5. This eliminates the risk that when the counter-coupling pieces 8 and 8' or 18 and 18' are separated from the coupling piece 6 or 6', respectively, hot glue may leak out of the corresponding glue application pipe 5 or 5' or 15 or 15' under pressure and injure the user due to its temperature.

[0072] For example, a security sensor may be a camera whose detection range extends into the secure area. A security sensor may also be a touch sensor that recognizes a door is open, through which a user can enter the secure area. In addition, there are other security sensors known to those skilled in the art, and therefore are not listed or mentioned in full.

[0073] Figure 3 Shown according to Figure 1 and 2 Embodiment of a coupling system 1 with a closing and locking housing 40 . Figure 3 A front view of the housing 40 is shown, so that Figure 3 The closing mechanism 60 located in the rear region of the housing 40 cannot be seen.

[0074] like Figure 3 As shown, the retaining rings 34 and 34' are now received in a form-fitting manner in the first part 42 of the housing 40. As mentioned above, the retaining rings 34 and 34' are part of the counter-couplings 18 and 18', on which the hose connections 15 and 15' are fixed, which lead from the coupling system 1 to the glue application device 72 (see Figure 5 ).Now Figure 3 It is also shown that the projections 12 and 12 ′ of the second portion 44 of the housing 40 are located in the slots 14 of the first portion 42 when the housing 40 is closed.

[0075] Figure 4 From Figure 3 The side opposite the perspective view of FIG. 1 shows an embodiment of the coupling system 1. Figure 4 In particular, the closing mechanism 60 can be seen again, which is fastened to the second part 44 of the housing 40 and is a screw-cylinder unit 62 .

[0076] When the housing 40 is closed and locked by the closing mechanism 60, the bolt 64 formed as a part of the closing mechanism 60 passes through the opening 27 of the tab 26 of the first portion 42 (see also Figure 1 ). As a result, the parts 42 and 44 constituting the housing 40 can no longer be separated from each other.

[0077] If the user wishes to access the coupling 6 or 6' located in the housing 40, the bolt 64 must be pulled out of the opening 27 so that the two parts 42 and 44 can be separated. The control device S is connected to both the closing mechanism 60 and the temperature sensor arranged in the housing 40. When the respective temperature of the heating coupling 6 or 6' detected by the temperature sensor drops to a predetermined target temperature that can exclude injuries to the user, the control device S retracts the bolt 64 from the opening 27.

[0078] Figure 5 An embodiment of a packaging machine 50 is shown with an embodiment of a gluing machine 70 according to the invention. Figure 5 Such a packaging machine 50 shown by way of example in the figure comprises a feed device 54, by which a plurality of stacks 53 are transported in the form of a plurality of outer packages, respectively. From the feed device 54, the outer packages are taken from the respective stacks 53 and are transferred to a buffer 56, which buffers the outer packages to the extent required for packaging the beverage containers.

[0079] The robot positions each outer package on a horizontal conveyor 52, which moves the outer package in the transport direction TR. For example, the outer package can be a carton, each of which can package a plurality of beverage containers. During transport in the transport direction TR, the outer package is moved in the horizontal conveyor 52 in the transport direction TR. Figure 5 The glue application format component, i.e. the spray head, shown in the figure at 74 applies glue to a tab of the corresponding outer packaging. Then, the corresponding tab is inserted, thereby closing the corresponding outer packaging. The applied glue then holds the tab in the inserted position.

[0080] The gluing machine 70 for applying glue comprises a coupling system 1 which again has Figure 5 The housing 40 (see Figures 1 to 4 ), and comprises a coupling 6 or 6' located in the housing 40. The gluing device 72 of the gluing machine 70 is fluidically connected to the coupling 6 or 6' of the coupling system 1 via a hose connection 15.

[0081] The gluing machine 70 comprises two different gluing format components 74 and 76, i.e. spray heads. According to the respective gluing process for gluing, it may be necessary to apply glue to the tabs of the outer packaging by means of the gluing format component 76 or by means of the gluing format component 74.

[0082] In this case, the glue format component 74 is coupled to the coupling 6 or 6' of the coupling system 1, wherein the counter-coupling 8 or 8' formed as a plug 9 or 9' is inserted into the coupling 6 or 6', which is connected to the additional glue tube 5' of the glue format component 74. However, the already inserted counter-coupling 8 or 8' can be separated from the coupling 6 or 6', so that as an alternative, the glue format component 76 can also be inserted into the coupling 6 or 6' via the corresponding counter-coupling 8 or 8' connected to the glue tube 5.

[0083] Therefore, the glue-coating format components 74 and 76 can be selectively coupled to the glue-coating device 72 via the coupling system 1 , so that glue is supplied to the glue-coating format component 74 or the glue-coating format component 76 via the glue-coating device 72 .

[0084] In order to be able to supply glue to a plurality of glue-coating format components 74 and 76, an additional glue-coating device 72 is not necessarily required.
