Definitions

  • the invention relates to a device for filling cans and a method for operating a device for filling cans.
  • the cans are usually connected to the filling valve in a gas-tight manner via a vertically movable centering bell when they are filled with a carbonated product.
  • the vertically movable centering bell is pressed against the upper edge of the can.
  • the contact pressure can be generated, for example, via a differential pressure chamber of the filling device.
  • a disadvantage of this technology can be that the contact pressure of the centering bell is comparatively high. Very thin-walled cans in particular could therefore be damaged or undesirably deformed, for example in the area of their upper edge.
  • the US 5 156 200 A discloses a filling valve in a counter pressure filling device for filling liquids into bottles or other types of containers with an open top.
  • the filling valve is provided with a sleeve which can descend towards an empty container below the valve and carries a deformable inner annular sealing element which can be moved into sealing engagement with the outer surface of the open end to center the container. The sealing element is then acted upon by a gaseous fluid to bear against the outer surface and to create a reliable seal.
  • the US 3 519 035 A also discloses a dosing device with a peripheral seal.
  • the invention is based on the object of creating an improved technology for filling cans, which preferably also enables safe and damage-free filling of cans with very thin walls.
  • the device has a filling valve for filling a can positioned under the filling valve with a (e.g. carbonated) filling material (e.g. beverage).
  • the device further has a gas channel for guiding a compressed gas, preferably compressed air.
  • the device further has a (e.g. annular and/or bellows) seal.
  • the seal is connected to the gas channel for receiving the compressed gas.
  • the seal is elastically deformable by the received compressed gas in a downward direction for pressing against a circumferential upper edge of the can positioned under the filling valve (e.g. by at least 3 mm, at least 4 mm or at least 5 mm).
  • the device can use the downwardly elastically deformable seal to securely seal the inlet gap between the can and the filling valve with comparatively low contact forces.
  • the contact force axial force
  • the contact force could be reduced by around 20% compared to a design with a vertically movable centering bell using the downwardly elastically deformable seal.
  • the contact force could be reduced from 675 N with a vertically movable centering bell to 550 N with the downwardly elastically deformable seal.
  • the design with the downwardly elastically deformable seal can also enable a rigid construction of the device that does not require a vertically movable centering bell or lifting device(s), which can significantly simplify the construction and operation of the device. This also improves the hygiene of the device.
  • the device can also be easily retrofitted to existing fillers, such as filler carousels, since existing pneumatic connections, which were previously used to fill the differential pressure chamber for the previously movable centering bell, can be used to supply the seal with the compressed gas.
  • the seal is inflatable by the compressed gas from the gas channel, and/or the seal is inflatable by the compressed gas from the gas channel in the direction elastically expandable downwards. This allows a secure seal to be achieved between the filling valve and the can in a structurally simple manner with comparatively low contact forces.
  • the seal has an annular (e.g. essentially flat) contact surface on its underside, which moves downwards when the seal is elastically deformed by the compressed gas received to press it against the circumferential upper edge of the can positioned under the filling valve.
  • annular e.g. essentially flat
  • the annular contact surface runs at an incline to a horizontal plane, preferably such that it rises from a circumferential inner edge of the annular contact surface to a circumferential outer edge of the annular contact surface.
  • the contact surface can thus advantageously provide a centering functionality with which the can can be centered under the filling valve.
  • the seal has an elastically deformable bellows section (e.g. with only one fold or several folds). In this way, a comparatively large elastic deformability of the seal in the downward direction can advantageously be enabled.
  • the seal has a preferably annular inner chamber into which the gas channel opens, and/or the seal has a substantially U-shaped cross-section.
  • a seal that can be inflatable downwards can thus be provided in a simple manner.
  • the device further comprises a preferably bowl-shaped cleaning cap, preferably a CIP cleaning cap.
  • the cleaning cap can preferably be moved under the filling valve and the seal (e.g. by means of a positioning device of the device), preferably by means of a lifting movement and a pivoting or sliding movement of the cleaning cap (e.g. by means of the positioning device).
  • the cleaning cap can particularly preferably comprise a chamber into which the annular seal can be elastically deformed in a downward direction. This advantageously enables thorough cleaning of both the filling valve and the seal.
  • the seal is arranged (e.g. essentially completely) in a seal receptacle which is preferably only open in the downward direction. This advantageously allows the seal to be guided downwards during elastic deformation, which also improves the stability of the seal in the loaded or elastically deformed state.
  • the seal receptacle on an inner peripheral side of the seal is formed by a preferably sleeve-shaped housing part of the device, which guides the seal in the downward direction during elastic deformation and preferably has at least one section of the gas channel.
  • the seal receptacle on an outer peripheral side of the seal is formed by a (e.g. further), preferably sleeve-shaped, housing part of the device, which guides the seal in the downward direction during elastic deformation. The seal can thus advantageously be guided securely and stabilized during pressing against the circumferential upper edge.
  • the device is free of a vertically movable centering bell and/or free of a lifting device for vertically moving the filling valve and/or free of a lifting device for vertically moving a can support (e.g. support plate and/or can clamp/gripper) of the device for supporting the can during filling.
  • the filler carousel has a plurality of devices as disclosed herein, which are preferably arranged distributed around a circumference of the filler carousel.
  • the container treatment plant can be designed for producing, cleaning, coating, testing, filling, closing, labeling, printing and/or packaging cans for liquid media, preferably beverages or liquid foodstuffs.
  • the cans can be designed as beverage cans or food cans.
  • the method comprises applying a compressed gas (e.g. compressed air) to a seal so that the seal elastically deforms in a downward direction (e.g. by at least 3 mm, at least 4 mm or at least 5 mm) and presses itself against a peripheral upper edge of a can.
  • the method further comprises filling the can (e.g. in a constant pressure filling method) with a (e.g. carbonated) filling material (e.g. beverage) from a filling valve while the seal is subjected to the compressed gas and presses itself against the peripheral upper edge.
  • a compressed gas e.g. compressed air
  • the method further comprises positioning a preferably bowl-shaped cleaning cap, preferably a CIP cleaning cap, under the filling valve and the seal (e.g. by means of a positioning device of the device and/or by a lifting and pivoting movement or a lifting and sliding movement).
  • the method can further comprise cleaning the filling valve and the seal by means of a cleaning fluid while the cleaning cap is positioned below the filling valve and the seal.
  • the seal can be exposed to a compressed gas at least temporarily and/or several times during cleaning, so that the seal deforms elastically in a downward direction into a chamber of the cleaning cap.
  • neither the can nor the filling valve performs a lifting movement to bring the filling valve and the can closer together prior to filling.
  • the can has a wall thickness of ⁇ 0.14 mm, ⁇ 0.13 mm, ⁇ 0.12 mm, ⁇ 0.11 mm or ⁇ 0.1 mm.

Instead, the elastic deformation of the seal 48 can overcome the inlet gap between the filling valve 14 and the upper edge 50 of the can 12 and seal during filling.
  • the Figure 3 shows a section of a Figures 1 and 2 modified embodiment.
  • the bellows section 54' of the seal 48 has a plurality of folds. The folds are arranged one above the other and connected to one another.
  • the Figure 4 shows an optional addition for the device 10.
  • the device 10 can have a cleaning cap 64.
  • the cleaning cap 64 is preferably designed as a so-called CIP cleaning cap or cleaning-in-place cleaning cap.
  • the cleaning cap 64 is preferably bowl-shaped.
  • the cleaning cap 64 can, for example, have a chamber 66.
  • the chamber 66 can be open at the top or have an opening at the top.
  • the chamber 66 can, for example, have a tub-shaped, pot-shaped or omega-shaped cross-section.
  • the chamber 66 can be dimensioned and arranged such that the seal 48 can be elastically deformed downwards into the chamber 66 when subjected to the compressed gas.
  • the chamber 66 can have a diameter that is greater than or equal to an outer diameter of the seal 48 and/or the seal receptacle 58.
  • An annular sealing element 68 may be arranged on a top of the cleaning cap 64.
  • the sealing element 68 may surround the top opening of the chamber 66.
  • a diameter of the sealing element 68 essentially corresponds to a diameter of a bottom side of the housing part 60.
  • the sealing element 68 can seal between the cleaning cap 64 and the housing part 60 when it sealingly contacts the housing part 60 from below (see Figure 4 ).
  • the diameter of the sealing element 68 can, for example, essentially correspond to an outer diameter of the housing part 60.
  • the sealing element 68 can seal between the cleaning cap 64 and the housing part 60 when it sealingly contacts the housing part 60 at its outer circumference (not shown in Figure 4 ).
  • the cleaning cap 64 can be moved by means of a purely schematically illustrated positioning device 70.
  • the cleaning cap 64 can perform a lifting movement, a horizontal pivoting movement and/or a horizontal sliding movement by means of the positioning device 70.
  • the cleaning cap 64 is arranged in a sealed manner under the filling valve 14 and the seal 48, the actual cleaning of the filling valve 14 and the seal 48 can take place.
  • a cleaning fluid can be supplied to the filling valve 14, which flows through the filling valve 14 and chamber 66 and in the process cleans the filling valve 14 and the seal 48.
  • the seal 48 can be exposed to the compressed gas during cleaning.
  • the seal 48 can then elastically deform downwards into the chamber 66 of the cleaning cap 64 and, for example, enable improved flushing of the seal 48.
  • the compressed gas can, for example, only be exposed to it temporarily during cleaning and/or several times in succession during cleaning.
  • the invention is not limited to the preferred embodiments described above. Rather, a large number of variants and modifications are possible, which also make use of the inventive concept and therefore fall within the scope of protection.
  • the invention also claims protection for the subject matter and the features of the subclaims independently of the claims referred to.
  • the individual features of independent claim 1 are each disclosed independently of one another.
  • the features of the subclaims are also disclosed independently of all features of independent claim 1 and, for example, independently of the features relating to the presence and/or configuration of the filling valve, the gas channel and/or the seal of independent claim 1.
