Definitions
- the invention relates to a system for treating cans, in particular beverage cans, with a carousel having a plurality of receiving points for cans and with a transport device for transporting the cans along a conveyor path, which connects to the transport carousel along a predetermined direction of movement in a transfer area, wherein a first section of the conveyor path has a decreasing curvature starting from a path predetermined by the transport carousel and merges into a second, in particular linear section of the conveyor path.
- the system can be provided in particular for filling and closing beverage cans, in which case unfilled beverage cans that are open on one side are then fed to the carousel, picked up at a distance from one another at the receiving points and filled with assigned filling valves on the carousel.
- a transition curve is provided on a first section of a conveying path of a transport device downstream of the carousel, on which the curvature starts from that of the Beverage cans on the transport carousel decreases.
- the liquid filled in the individual cans is pushed outwards, so that the filling height on the radial outside is higher than on the opposite inside.
- dynamic forces must be taken into account. Specifically, if the filled cans were transferred directly from a circular path to a linear movement, the liquid that was initially pushed outwards by the centrifugal forces would suddenly slosh back, so that splashing out of the filled cans cannot be ruled out.
- an alley is formed by limiting the beverage cans on both sides using guide railings. It cannot be avoided that the beverage cans collide against the guide railings or against each other along the conveying path of the transport device. Such contact also poses a risk of liquid escaping through splashes, especially if the cans are processed at high production speeds. Thanks to the lateral support with the fixed guide rails, the cans can also be placed in an undesirable rotation.
- the invention is based on the object of specifying a system for treating cans, in particular beverage cans, with which cans can be transported particularly gently at high speeds, preferably also minimizing the risk of contamination. Furthermore, a procedure for operating a corresponding system should be specified.
- the subject of the invention and solution to the problem are a system according to patent claim 1 and a method for operating the system according to patent claim 12.
- the transport device has a rotating drive means and drivers arranged on the drive means for transporting the cans along the first and second sections, the course of which The conveyor route is provided by a guide.
- the cans are each guided with an assigned driver, which prevents the cans from hitting one another and avoids impacts along the direction of movement.
- the guide acts as a guide track in the first section on the drive means and/or on the drivers. This ensures that the drivers themselves move exactly along the first section of the conveying path with a decreasing curvature, so that a relative movement between the drivers and the cans guided by them can then be avoided.
- the cans in the transport device can be guided with their base on a sliding surface.
- the drivers are provided as the only guide means of the transport device for circumferential guidance of the cans. Accordingly, in normal operation, no fixed side guide rails, boundaries or the like are provided, so that lateral stops or lateral rolling of the cans in the transport device are then excluded. In principle, however, it is possible to provide corresponding fixed elements at a distance from the actual conveying path as a kind of emergency guide or emergency stop if individual cans are not guided in the desired manner solely by the assigned drivers.
- the drivers each have a concave guide receptacle for the cans. Seen in the transport direction, the guide receptacle is then set back in its center, whereby the term concave in the context of the invention is not limited to an arcuate course, but can also be formed from straight sections.
- the concave guide receptacle can be U-shaped or V-shaped, for example.
- the concave shape of the guide holder ensures that the individual cans can be transported particularly stably in a desired position. It should also be noted that in the context of the invention, the centrifugal force is continuously returned due to the decreasing curvature along the first section of the conveying path of the transport device, but tangential forces still act on the can.
- the concave design of the guide holder allows the remaining forces to be absorbed, so that the cans are guided particularly evenly and without vibration.
- the concave guide holder also achieves reliable centering of the cans in relation to the respective associated drivers.
- the concave guide receptacle can, for example, be V-shaped, with the internal angle pointing in the direction of movement being, for example, between 110° and 170°. It is preferably provided that deflection axes of the transport device, around which the drive means is guided, are parallel to an axis of rotation of the carousel.
- the deflection axes of the transport device are also vertical.
- the rotating drive means then runs at least essentially in a horizontal plane.
- the drive means can in particular be designed as a chain or as a belt.
- the drivers can be arranged in a simple manner in the area of the connecting axes of successive chain links.
- the first section of the conveying path of the transport device can, for. B. have a clothoid shape, which is also further explained in DE 10 2019 117 377 A1.
- the transport device is provided in order to remove filled and not yet closed cans, in particular beverage cans, from the carousel, in which case a lid support device can then be arranged on the second section of the conveying path of the transport device.
- a lid support device can then be arranged on the second section of the conveying path of the transport device.
- the cans are closed directly with the lids, so that the closed cans can then be guided and redirected in a less complex manner. If it is intended to fill the cans on the carousel, in particular with a drink, an assigned filling valve must also be provided at the receiving points.
- the invention also relates to a method for operating the system described above, whereby unfilled cans that are open on one side are fed to the carousel, picked up at a distance from one another at the receiving points and filled at the carousel, the drivers of the transport device being in intervene between the successive cans in the transfer area and transport them preferably as a single peripheral guide along the first section to the second section and the cans are provided with a lid and closed along the second section.
- FIG. 2 is a partial view of the system according to FIG. 1,
- Fig. 3 is a perspective view of a transfer area between a carousel and a downstream transport device of the system.
- Fig. 1 shows a schematic view of a system for treating cans 2 in the form of beverage cans.
- the system comprises a carousel 3 having a plurality of receiving points 1 for cans 2 and a transport device 4, which connects to the carousel 3 along a predetermined direction of movement in a transfer area 5.
- a first section 6 of a conveying path of the transport device 4 points from one through the Carousel 3 predetermined circular path has a decreasing curvature and merges into a second, linear section 7 of the conveyor path.
- the cans 2 guided on the carousel 3 are filled via filling valves (not shown), the filled and open cans 2 then being guided to a lid closing machine 8 by the transport device 4.
- the cans 2 are closed with lids placed on them along the second section 7 of the conveying path of the transport direction 4.
- the filled liquid is forced outwards, with the evenly decreasing curvature along the first section 6 of the conveying path being intended to slowly reduce the centrifugal force and thus avoid splashing out or spilling over.
- the cans 2 can, however, also be transported further in comparatively short sheets.
- the transport device 4 has a rotating drive means 9, with deflection axes 10 of the transport direction 4 being parallel to a rotation axis 11 of the carousel.
- the axis of rotation 11 and the deflection axes 10 are usually aligned vertically, so that the drive means 9 runs in a horizontal plane.
- the drive means 9 is designed as a chain, with a design as a belt also being considered, for example.
- drivers 12 are provided on the drive means 9 for transporting the cans 2 along the conveying path, the course of the conveying path being predetermined by a guide 13.
- the guide 13 acts on the drive means 9 in the form of the chain, whereby the guide 13 can be designed, for example, as a slot in which the chain is inserted and guided on the underside.
- the drivers 12 are attached in the form of fingers to the top of the lying chain as a drive means 9.
- the drivers 12 attached to the drive means 9 reach between the cans 2 that are still held and guided on the carousel 3. As soon as the cans 2 are released from the carousel 3 at the corresponding receiving points 1, the further path of the cans 2 is determined by the drivers 12 determined.
- the drivers 12 each have a concave guide receptacle 14, which is V-shaped in the exemplary embodiment shown.
- the concave guide receptacle 14 results in centering during the transport of the cans 2 along the direction of movement, whereby a relative movement between the drivers 12 and the cans 2 can be completely or at least largely avoided.
- the centrifugal force acting on the liquid in the can 2 is slowly reduced, so that an inclination of the liquid in the cans 2 is reduced slowly and without splashing or sloshing .
- the guide receptacle 14 can, for example, have an internal angle between 110° and 170°, for example approximately 135°.
