Definitions
- the invention relates to a pack forming device with two transport devices located opposite one another, the transport devices being designed to group and transport containers into packs by means of a plurality of guide elements that can be moved along a circumferential guide path, the transport devices each having a drive device for driving the guide elements in one transport direction .
- Pack-forming devices of the type described above are basically known from the prior art and are used, for example, to combine containers into packs and to fix them together.
- the invention relates to pack forming devices in the beverage industry, in which case the containers can be beverage containers, for example bottles made of plastic or glass, or beverage cans.
- the containers are first filled with the appropriate filling medium in a beverage bottling plant and then, if necessary, after further treatment steps, such as e.g. B. a labeling, a corresponding pack forming device.
- the size and design of the pack to be formed in the pack forming device is measured here on the basis of the grouped guide elements and on the basis of the two transport routes.
- six-packs three guide elements of a transport device are grouped together and brought together with a corresponding further transport group of the other transport device.
- a generic configuration is known, for example, from EP 3 038 927 B1.
- the individual containers are used to The containers are fixed to one another with an adhesive.
- an adhesive is first applied to discrete points on the container and then the containers are connected to one another via the adhesive points.
- the two transport devices are arranged relative to one another in such a way that the containers transported therein are pressed against one another to a certain extent.
- Guide elements are provided for guiding the containers in the transport devices, which are moved continuously on the transport devices.
- a chain drive which is connected to the guide elements via a bolt, is provided as the drive device for the guide elements.
- the present invention is based on the object of specifying a pack forming device which, compared to the devices known from practice, is characterized by improved transport of the guide elements and in particular by a longer service life and lower maintenance costs.
- a pack forming device according to claim 1. Accordingly, it is provided that the guide elements are at least partially connected to the respective drive device via a connection element, with a compensating movement of the guide elements to the drive device transverse to the connection element Transport direction is made possible. Consequently, on the one hand, force can be transmitted in the transport direction, while at least one compensating movement is made possible transversely to the transport direction, thereby preventing the guide elements from jamming on the guide track.
- connection elements are preferably each formed from a bolt or a bolt section, which engages in the direction of transport in a receiving groove running transversely to the direction of transport of the respective drive device, in particular engages in a form-fitting manner. Consequently, this receiving groove runs essentially transversely to the transport device and has a length which is sufficient to enable the necessary compensating movements.
- the width running in the transport direction essentially corresponds to the width of the bolt or bolt section engaging in the groove, so that a direct transmission of force from the receiving groove to the application element can take place. It goes without saying that a large number of grooves are provided circumferentially on the respective drive device, so that a large number of guide elements can also engage in one of these receiving grooves via a respective connection element.
- the ratio between the length of the receiving grooves and the width of the receiving grooves is preferably between 2:1 and 6:1, particularly preferably between 3:1 and 5:1.
- the width of the receiving grooves is also preferably between 10 and 30 mm, preferably between 15 and 25 mm, particularly preferably between 17 and 20 mm.
- the length of the receiving grooves is between 50 and 90 mm, preferably between 60 and 80 mm and particularly preferably between 70 and 75 mm.
- the bolts or bolt sections can be designed to be adjustable or detachable.
- a particularly preferred embodiment provides that the bolt sections are designed to be foldable. This makes it possible to decouple the guide elements from the drive device in a simple manner. This is necessary, for example, in order to be able to remove the guide elements from the guide track or to introduce new guide elements into the guide track.
- the drive devices each have a revolving element to which the guide elements are fastened.
- This revolving element can be, for example, the transport chain of a chain drive.
- the drive devices are each formed as a toothed belt drive with a transport belt running along the drive pulleys as the rotating element.
- a toothed belt drive is a drive method in which the transport belt is designed with teeth on one side, with the teeth engaging in a form-fitting manner in toothed drive pulleys. By rotating these drive pulleys, the transport belts and elements arranged on them are then also moved.
- the transport belt is usually made of a plastic.
- a transport belt made of neoprene or chloroprene rubber has proven particularly advantageous.
- toothed belt drives are characterized by their high dimensional stability, with the problem of chain elongation in particular being eliminated.
- chain drives it has been shown that the transport chain lengthens to an increasing extent as the operating time progresses due to the loads acting on it. As a result, the transport chain must be re-tightened.
- such a tensioning process is also required for the transport belt of a toothed belt drive.
- the drive pulleys of a transport direction are designed to be at least partially adjustable.
- the two drive pulleys can be moved toward or apart from one another, as a result of which the corresponding tension of the transport chain or the transport belt is set.
- this also changes the circulating path for the transport chain or the transport belt, so that the movement of the guide elements on the one hand and the movement of the transport port belt or transport chain trained to current element fall apart on the other hand.
- enabling a certain mobility transverse to the transport direction for the guide elements is of particular importance in order to avoid the previously mentioned problem of jamming.
- the receiving grooves are preferably formed on the transport belt.
- the transport belt can be formed integrally with these receiving grooves.
- the receiving grooves are each formed on a coupling unit formed separately from the transport belt, these coupling units then being fastened to the transport belt.
- a screw connection is particularly suitable as a fastening, although the invention is not limited to such a fastening.
- Gluing, riveting or the like also represent suitable attachment variants.
- releasable attachments have proven to be particularly advantageous since the individual coupling units can be replaced in this way without a complete replacement of the transport belt being necessary.
- connection elements guided in the receiving grooves widen or wear out the receiving grooves.
- the connection elements guided in the receiving grooves widen or wear out the receiving grooves.
- by replacing individual coupling parts it can be ensured that a positive fit in the transport direction and thus a power transmission that can be offset is made possible again.
- a preferred embodiment of the invention provides that the receiving grooves are arranged on the drive device with a pitch of between 60 and 100 mm.
- the pitch is particularly preferably between 70 and 90 mm.
- a pitch means a length which is calculated from the ratio between the total length of the transport belt and the number of coupling units. In this context, a pitch of 80 mm has proven to be particularly preferred. With an exemplary number of 96 guide elements per transport direction, de then result in a total length of the conveyor belt of 7680 mm or 7.68 m.
- a preferred embodiment of the invention provides that the transport devices are set up to move the containers along transport paths arranged parallel to one another.
- the two transport sections are located on a side facing the respective other transport device, so that the two transport sections are directly adjacent to one another.
- the guide elements in the two transport devices are arranged and guided in such a way that the guide elements of the two transport devices are directly opposite one another along the two transport sections.
- the guide elements are combined in transport groups.
- 2, 3, 4 or more guide elements can each be combined within a transport device to form a corresponding transport group.
- These guide elements then usually have a smaller distance within a transport group than the distance between two consecutive transport groups.
- the guide elements can also be connected to one another within a transport group. With such an embodiment, it is sufficient if only one of the guide elements of a transport group is connected to the drive device, this guide element then also influencing the movement of the other guide elements within the transport group. If a synchronized movement of the transport groups between the individual transport devices is then also provided, the containers of the two transport groups of the two transport devices running synchronously with one another can form a bundle be summarized, e.g. For example, with a transport group size of three guide elements, bundles are formed from a total of six containers (2 times 3 containers). Such a container size is colloquially referred to as a six-pack. It is of course also within the scope of the invention to provide other container sizes, e.g. B. 2*4 containers.
- a development of the invention also provides that the guide tracks are each formed in an oval shape with two essentially straight track sections and two curved sections connecting the straight track sections to one another.
- the transport routes are preferably each arranged on a substantially straight path section, with the further straight section being arranged on a side of the respective transport devices opposite the transport routes.
- the two trajectories are then arranged accordingly on the drive pulleys of the drive device and enable the individual transport elements or transport groups to be returned and fed in again.
- the present invention is based on the finding that preferably the essentially straight path sections are each connected to the curved sections by transition sections, the transition sections having an increasing curvature starting from the essentially straight path sections in the direction of the curved sections.
- This increasing curvature causes the guide elements to be deflected over a certain section of the guideway into the actual curvature of the curved path, with the maximum curvature of the transition sections corresponding to the curvature of the curved path.
- the containers are relatively soft in and out of the cam tracks led out, so that a smooth movement behavior of the guide elements adjusts within the guide.
- the transition sections each have a length which corresponds to between 0.5 and 4%, preferably between 1 and 3.5%, of the length of the guideway.
- a total of four transition sections are also provided, which each have a transition section in an inlet and an outlet.
- a preferred embodiment also provides that the guide elements are guided on several contact levels on the guideway.
- this means a plurality of installation levels, which are arranged one above the other in a vertical direction of the transport device.
- This vertical direction means a direction in which the containers are set up with a container axis and which is arranged both perpendicularly to the transport direction and perpendicularly to the transverse direction.
- the guide track can also have a different length in the individual guide planes, in which case the transition sections can then also preferably be arranged offset to one another.
- the transport devices each have between 50 and 150, preferably between 80 and 120 guide elements.
- the guide elements are preferably designed as carriages.
- the guide elements can, for. B. each have several rollers, by means of which the guide elements are guided on the guideways.
- the respective guide element can have, for example, at least one pressure head, preferably at least two pressure heads arranged one above the other, each with a contact surface for a container.
- the pressing heads are expediently format parts.
- the transport devices are preferably each preceded by an adhesive application device for applying an adhesive to the containers in the direction of production.
- the invention also relates to a method for forming bundles from containers using a bundle forming device according to claim 16, wherein the transport devices of the bundle forming device are supplied with containers and the containers are transported in transport groups consisting of a plurality of guide elements along the transport routes.
- the containers are preferably first provided with adhesive before being introduced into the transport devices and then the containers assigned to a transport group are connected to one another via the adhesive.
- the containers assigned to a transport group of one of the transport devices are also preferably connected to the containers assigned to a further transport group of the other transport device via the applied adhesive.

- 1 shows a pack-forming device according to the invention, in which containers 1 are fed to a treatment station 3 by means of a first transfer starwheel 2 and wherein adhesive is applied in treatment station 3 by means of adhesive application devices 4 .
- the containers 1 are then transferred via a further, second transfer star wheel 5 to two transport devices 6, 7 located opposite one another.
- the containers 1 are grouped into bundles and transported along transport routes 8, 9 arranged parallel to one another. As can be seen from Fig. 1, the two transport routes 8, 9 running parallel to one another are located between the two transport devices 6, 7.
- the containers 1 within the transport devices 6, 7 are grouped into three containers 1 per transport route 8, 9, with a total of six containers 1 forming on the basis of the two transport routes 8, 9. Due to the application of adhesive, the individual containers 1 can be fixed to one another, for which purpose the containers 1 are pressed against one another to a certain extent and the adhesive hardens during transport on the transport sections 8, 9.
- FIG. 1 A detailed design of the transport devices 6, 7 is shown in FIG. It is clear from this that the transport devices 6, 7 have a multiplicity of guide elements 10 which can be moved circumferentially along one of the transport devices 6, 7 in each case.
- a drive device 11 is provided, which is designed for both transport devices 6, 7 as a toothed belt drive.
- two drive pulleys 12 are provided for each transport device 6, 7, which move a transport belt 13 in a rotating manner.
- the guide elements 10 are connected to the transport belts 13 so that a movement of the drive pulleys 12 causes a movement of the transport belt 13 and then also a movement of the guide elements 10 .
- the guide elements 10 form, according to the embodiment of FIG.
- the arrangement and design of the guide elements 10 can be changed in principle and can be selected depending on the desired pack formation. According to the exemplary embodiment of FIG. 2, a total of 96 guide elements 10 are provided per transport device 6, 7, resulting in a total of 192 guide elements 10 for the entire pack forming device.
- coupling units 14 are arranged and fastened on the transport belts 13 and serve to connect the guide elements 10 to the corresponding drive devices 11 or to the transport belts 13 .
- the coupling units 14 have a receiving groove 15 .
- a guide element 10 engages in this receiving groove 15 with a bolt section 16 and can be moved as a result of a movement of the transport belt 13 .
- the bolt section 16 is designed to be foldable, so that the guide element 11 can be connected to the drive device 11 or not, as desired. Detachment can be necessary, for example, when the guide element 10 is to be removed from the corresponding transport device 6, 7.
- the guide element 10 is guided along a curved or guide track 18, a curved section of the guide track 18 being illustrated in FIG.
- the curved sections are arranged in the area of the drive pulleys 12, it being clear in particular from FIG. 2 that the drive pulleys 12 can be moved along an adjustment direction V in order to be able to tension the transport belt 13 in a suitable manner.
- the bolt section 16 engages in the previously mentioned receiving grooves 15, which enable a compensating movement of the guide elements 10 transversely to the transport device T.
- the bolt section 16 can move along the receiving grooves 15 and thus bring about a length compensation.
- FIGS. 4 and 5 A comparative view of FIGS. 4 and 5 also makes it clear that the guideway 18 is designed with a plurality of guide planes arranged in the vertical direction Z, so that the guide elements 11 are correspondingly supported on a plurality of horizontal guide planes of the guideway 18 .
- transition sections 19 which define a transition from an essentially straight path section to the curved section.
