Definitions
- the invention relates to a treatment device for containers, in particular for beverage containers, with a rotary drive that can be driven to rotate about a central axis of rotation and container receptacles that are arranged on the rotary conveyor and are set up to transport containers along a transport path that extends over a peripheral section of the rotary conveyor, the container receptacles are drivable in rotation at least in sections along the transport route and wherein a braking device is assigned to each of the turntables.
- both the transport carousel and the container receptacles themselves are designed to be rotatable, so that they can be transported along the transport path not only due to the rotation of the transport carousel. Rather, during transport, the container receptacles can also rotate about themselves or rotate in relation to the transport rotor.
- the invention relates in particular to treatment devices in the beverage industry.
- the containers in this case are beverage cans, in particular cans made of metal, for example, or bottles, which can be made of glass or plastic, for example.
- These containers are then usually subjected to a number of treatment steps. This can involve, for example, filling, pasteurization, labeling or the formation of individual containers.
- the containers are transported between individual treatment devices, with the containers not only being treated within the treatment device according to the invention, but also being transported further.
- the treatment device has a rotating transport rotor, with the containers usually being moved in a rotating manner by means of a constant speed.
- a treatment device of this type is known, for example, from publication EP 2 785 596 B1, the containers being transported during transport on the transport carousel via container receptacles designed as turntables past a device for applying adhesive. With the help of this adhesive it is then possible to join the containers together to form bundles.
- the permanent braking also means that the container receptacles run through the transport route in an approximately constant orientation, so that the container receptacles are soiled unevenly with the adhesive precisely when additional adhesive is applied.
- the invention is based on the object of improving the known treatment devices in such a way that they can have a longer service life and less or more uniform contamination.
- variable braking means that the braking devices act on the container receptacles with a braking force of different magnitudes along the braking section.
- the areas of the transport rotor that are outside of the transport route can also be essentially unbraked, so that the container receptacles can rotate freely to a certain extent, which means that, especially when an adhesive is applied, contamination with the adhesive spreads to a broader area of the Container pick-up focused.
- the container receptacles can also be at least minimally braked in areas outside the transport route.
- the braking section extends over at least 10%, preferably at least 15% of the transport route.
- a preferred development of the invention provides that the braking section extends over at most 40%, preferably at most 30% of the transport route. Accordingly, variable braking or braking with variable braking force takes place only over a predefined section of the transport route, with this braking section preferably being arranged at the rear end of the transport route. It is of course also possible within the scope of the invention for the container guides to be braked in areas outside of the braking section. However, this can then be constant and/or at a much lower level than the treatment devices known from the prior art.
- the braking devices are preferably set up in such a way that the braking force generated by the braking devices preferably increases along the braking section.
- the braking force can then, for example, increase linearly and/or exponentially at least in some areas along the braking section.
- this can increase at least by a factor of 2, preferably by a factor of 4, very particularly preferably by a factor of 8 in the braking section.
- a preferred embodiment of the invention provides that the braking device can be actuated via a braking control curve.
- a braking control cam is arranged along a section of the transport route or along the braking section, via which the braking effect of the braking devices can be adjusted.
- the braking devices each have an actuating element which is guided along the braking control cam and is set up to brake the container receptacles via a braking element.
- This control element can be adjusted, e.g. rotated, via the braking control curve, as a result of which the braking force generated by the braking devices is adjusted.
- at least one brake shoe can be pressed against a rotating drive shaft of the container receptacles, with the extent of the contact pressure determining the resulting braking force.
- the braking control curve is designed accordingly.
- the braking control curve therefore preferably has a varying distance from the central axis of rotation along the braking section.
- the adjusting element rests radially on the outside in the braking section on the braking control curve, with the braking control curve having an increasing distance along the braking section from the central axis of rotation. Due to the increasing distance, the adjusting element rotates and presses a brake shoe against the drive shaft of the container holder.
- the actuating element can also rest on the braking control cam radially on the inside.
- each of the container receptacles is assigned a drive device for rotating the container receptacles.
- the drive devices each have a drive actuating element, which is guided on a drive control cam arranged at least in sections along the transport route.
- a drive control cam arranged at least in sections along the transport route.
- the drive control elements each act on a drive shaft of the container receptacles, with the drive shafts having a drive axis of rotation which is arranged parallel to the central axis of rotation of the transport rotor.
- a gear in particular a planetary gear, is preferably arranged between the drive setting elements and the associated container receptacle, which is designed such that the rotational speed of the container receptacles is increased compared to the rotation of the drive setting element.
- a translation between 1:10 and 7:10 is provided. With the help of such a transmission, it is then possible for the container receptacles and thus also the containers to be rotated between 300 and 800°, preferably between 340 and 740°, along the transport route.
- An embodiment in which a rotation of 720° takes place is very particularly preferred.
- the invention is not limited to the inclusion of a transmission. It is sufficient if the drive devices are set up and arranged in such a way that the aforementioned rotation of the container receptacles can be effected.
- an embodiment with an additional planetary gear has proven to be particularly effective. At the same time, however, the inaccuracies and instabilities are amplified by the translation, so that effective braking is required, especially at the end of the transport route.
- the container receptacles are also designed as turntables.
- the containers are arranged on the container receptacles and are thus supported on the container receptacles solely via the container bottom.
- the invention also preferably provides that at least one application device is assigned to the transport carousel, which is set up to apply an adhesive, a label and/or a decoration to the containers within the transport path. This preferably takes place during transport along the transport route, but not within the braking section. For example, the container is guided past the application device in a rotating manner and only then is the corresponding container holder successively braked. A test device, for example, can then also be arranged along the braking section, which checks the correct application or the correct application of the application, but which itself does not intervene in the treatment of the containers.
- the invention also relates to a method for transporting and treating containers in a treatment device according to the invention, in which the containers are fed to the treatment device and arranged on the container receptacles, the containers being moved along the transport path via the transport rotor and being driven in rotation on the container receptacles, and the rotation of the container receptacles being braked in varying ways along the braking section.
- the container holders preferably rotate between 300° and 800°, particularly preferably between 340° and 740°, during the movement along the transporter route.
- an adhesive, a label and/or a decoration is applied to the containers within the transport path, for which purpose the containers are preferably guided past an application device in a rotating manner and a varying deceleration takes place only after the application in question has been applied .
- FIG. 1 shows a section of a pack forming device with a treatment device according to the invention
- FIG. 2 shows the device according to FIG. 1 in a plan view
- FIG. 4 shows a detailed view of the treatment device according to FIG.
- FIG. 1 shows a section of a pack forming device in which the container 1 is transported in the production direction P along two parallel tracks are, the tracks are merged at the end to summarize the container 1 to bundles.
- the containers 1 in the respective track are initially aligned in a predetermined manner in an alignment device 2 and transferred to the treatment device 4 according to the invention via a transport star wheel 3 .
- FIG. 2 makes it clear that an application device 5 (not shown in FIG. 1) is provided, via which an adhesive is applied to the containers 1 and the containers 1 are brought together from both tracks at the end of the treatment device 4 and are fixed to one another to form containers via these adhesive points.
- the containers 1 shown are, for example, metal cans.
- the treatment device 4 according to the invention can also be used for bottles, e.g. made of glass or plastic, in particular PET.
- the two treatment devices 4 each have a central axis of rotation D, about which a rotary transporter 6 is driven in rotation.
- one treatment device 4 is provided for each of the two tracks according to the illustrations shown, the description below is limited to the treatment device 4 of only one track, with both treatment devices 4 being designed analogously.
- Container receptacles 7 in the form of turntables are arranged on the transport gyroscope 6 , the containers 1 being placed on these turntables at the start of the transport route T and then being transported along the transport route T as a result of the rotation of the transport gyroscope 6 .
- the container receptacles 7 are also driven in a rotatable manner in relation to the transport rotor 6 . This takes place with the aid of a drive control cam 8.
- the drive cam 8 is designed in such a way that it decreases continuously along the transport path T in relation to the radial distance from the central axis of rotation D.
- the container receptacles 7 designed as turntables are also connected via a planetary gear each connected to a drive control element 9, which is guided along the drive cam 8 and the decreasing distance to the central axis of rotation D causes a rotation of the drive control elements 9 and thus also of the container receptacles 7.
- this rotational movement is amplified in such a way that the containers 1 are rotated by 720° along the transport path T.
- FIG. 3 shows a braking device 10 with which it is possible to variably brake the rotation of the container receptacles 7 designed as turntables in a braking section B extending at least in sections along the transport path T.
- a braking cam 11 is provided in the treatment device 4, along which an actuating element 12 of the braking device 10 is guided (cf. FIG. 4).
- This brake control curve 11 is set up in such a way that the actuating element 12 is actuated in the direction of a drive shaft 13 (only indicated schematically) of the turntable, as a result of which a brake shoe with a brake lining 14 is then pressed against the drive shaft 13 and the turntable can thus be braked.
- the brake control curve 11 is formed with a radially increasing outward diameter, so that the actuating element 12 along the brake Section B is increasingly actuated and the braking force acting on the drive shaft 13 is increased.
- the braking section B does not extend along the entire transport route T.
- the braking section B preferably extends over at least 10%, preferably at least 15% of the transport route T and at most over 40%, preferably over at most 30% of the transport route T.
- a spring element 15 is provided in the respective braking device 10, which ensures that the braking effect can be reduced to a minimum or completely eliminated if the braking control curve 8 is not present.
