Description

1 / 16 MACHINE FOR FILLING AND CLOSING CANS UNDER HYGIENIC CONDITIONS, METHOD FOR FILLING AND CLOSING CANS UNDER HYGIENIC CONDITIONS, AND LID PLACING DEVICE FOR FILLING THE CAN

[001] The present invention relates to a machine, a method and a lid-placing device for filling and closing cans under hygienic conditions in accordance with the preamble of the independent claims.

[002] Several machines for filling and / or closing containers are known in the state of the art. The purpose of the machines is to automatically fill and close a large number of containers. A particular challenge is to perform the filling and closing of cans in the shortest possible time and under maximum hygienic conditions.

[003] Universal patent document WO 2011 / 029609 discloses a machine for the sterile filling of products, in particular, beverages in bottles or similar containers. For this purpose, containers are introduced into a housing, which forms a sterile space. The housing comprises both a device for filling the containers and a device for closing the containers. In a first step, the containers are filled with the corresponding beverage, and then, in a second step, they are transferred to the closing device via a container transfer device. This procedure is time-consuming and involves high expenditure and costs in order to move the corresponding space to a sterile environment.

[004] In addition, a device for treating beverage containers is known from German patent document DE 197 39 326, which involves enclosing the beverage containers during treatment by a Petition 870260051443, dated 05 / 28 / 2026, p. 6 / 54 2 / 16 of the carcass is placed under sterile conditions. To achieve this, beverage containers on a conveyor belt are separated from each other by portals, which, at the entrance of the beverage containers into the device, form a closed space under sterile conditions. A disadvantage of this device is that the conveyor belt needs to be stopped for the duration of the treatment.

[005] A device for closing containers is known from German patent document DE 44 24 098. During the movement of the container along the conveyor belt, the closing cap is fed into the mouth of the container, such that between the mouth of the container and the closing cap there is an access slot that forms a treatment zone. In the treatment zone, a sterile treatment is carried out before the closing process in the area of ​​the mouth of the container. In this case, only the container closing process occurs under sterile conditions. This has the disadvantage that the degree of sterilization in total during the filling process is not particularly high, and in certain circumstances, the shelf life of the filling material is not long.

[006] The task of the present invention is to create a machine for filling and closing cans, which avoids the disadvantages of the prior art and, in particular, to create a machine, a method and a lid-placing device that in the shortest possible time and under maximum hygienic conditions fills and closes beverage cans.

[007] This task is solved by a machine, by a method and by a lid-setting device for filling and closing cans according to the independent claims.

[008] According to the invention, the machine for filling and closing cans under hygienic conditions comprises a hygienic compartment, a lid placement device and a Petition 870260051443, dated 05 / 28 / 2026, page 7 / 54 3 / 16 inlet opening for a filling material. The lid placement device is located in the hygienic compartment, and the inlet opening is formed in the hygienic compartment. In the case of use according to the provisions, one or more cans can be coordinated to the hygienic compartment, and the hygienic compartment can be moved together with the can(s) inside the machine.

[009] In this context, can closure should be understood as at least placing a can lid onto the can. Pressing the lid down onto the can or also joining the can lid to the can by means of current joining techniques, preferably by folding, ensures that the can remains closed for further processing.

[010] In the case of cans to be filled and sealed in this machine, these are cans that will be filled with a liquid and / or solid filling material. Preferably in this case, these are beverage cans, which are filled with a liquid filling material, in particular, beverages.

[011] In this case, a hygienic compartment should be understood as a space enclosed from the environment that is under hygienic conditions. In this case, hygienic conditions should be understood as conditions that correspond at least to a hygiene class I classified according to VDMA (No. 2 / 2000, 3rd Edition 2016), preferably, however, corresponding to a hygiene class III or higher, classified according to VDMA (No. 2 / 2000, 3rd Edition 2016).

[012] Alternatively, the lid placement device may be formed wholly or partially outside the hygienic compartment.

[013] The advantages of the present machine consist in the fact that the cans are filled and closed, in such a way that their material Petition 870260051443, dated 05 / 28 / 2026, page 8 / 54 4 / 16 filling has a long shelf life and, at the same time, efficient filling and closing are possible in a short time. Additionally, under these circumstances, pressure ratios can be optimized because quick filling and capping is also feasible with foam and powder substances. An overpressure of up to 65 bar is used, preferably between 0 and 40 bar.

[014] Preferably, a filling device is formed in the inlet opening, or a filling device can be introduced into the inlet opening.

[015] This has the advantage that efficient filling and closing of the can is possible during transport.

[016] Preferably, the filling device comprises a flow sensor for determining the filling volume.

[017] A fill level sensor can be an alternative to the flow sensor for determining the fill volume, which determines whether a predetermined fill level of the fill material has been reached, or a weighing device that determines the achievement of a predetermined weight.

[018] The advantage of a fill level sensor of this type or one of the alternatives shown is that it allows for automatic and reliable filling of the cans with the same volume of filler material at all times.

[019] Preferably, the cap-placing device comprises a cap-carrying device as well as a tamping arrangement and a splicing device. But the cap-placing device may also comprise a cap-carrying device and a tamping arrangement or a cap-carrying device and a splicing device.

[020] The lid-setting device picks up the lid using a gripping mechanism and transports the lid to the can. The Petition 870260051443, dated 05 / 28 / 2026, p. 9 / 54 5 / 16 The gripping mechanism can be a suction mechanism, a magnetic mechanism, or a guide system through which the lid is moved.

[021] Alternatively, the splicing device may be disposed wholly or partially outside the hygienic compartment.

[022] The advantage of the lid placement device is that the can lid is fed automatically and while this is happening, various processes can be carried out on the lid, such as cleaning the lid or aligning the lid, etc.

[023] Preferably, an airlock compartment is located in the hygienic compartment.

[024] The advantage of the air chamber compartment is that during the can filling process, the lid can already be prepared for placement on the can at a later time. Preparation processes may include cleaning or aligning the lid, etc.

[025] Preferably, using the lid transport device, lids are transported along a transport path from the air chamber compartment to the hygienic compartment.

[026] Transporting the lid via an air chamber compartment has the advantage that various processes such as cleaning, lid alignment, etc. can be performed on the transported lid.

[027] Preferably, one or more inlets and outlets are arranged in the air chamber compartment.

[028] An air chamber compartment with one or more inlets and outlets is, on the one hand, advantageous in order to effectively connect the air chamber compartment with the hygienic compartment, but on the other hand, it is also possible to introduce devices or covers into Petition 870260051443, dated 05 / 28 / 2026, p. 10 / 54 6 / 16 air chamber compartment.

[029] Preferably the air chamber compartment comprises a cleaning device.

[030] A cleaning device used herein is used for the partial or complete cleaning and disinfection of the lid and / or compartment and / or parts thereof. The cleaning device may comprise an introduction of gaseous, liquid or solid cleaning media, or may occur with the aid of particle radiation or electromagnetic radiation or with a mechanical device. Mechanical devices may be brushes, sponges, scrapers, etc.

[031] The advantage of having a cleaning device in the air chamber compartment is that the lids can be cleaned and prepared for introduction into a hygienic environment, while at the same time the can can be filled in the hygienic compartment. This leads to shorter processing times.

[032] Preferably, the air chamber compartment comprises an inclined base. In addition, in the area of ​​the lowest point of the base, according to the determination of the machine's use, the base comprises a discharge opening.

[033] The discharge opening serves to distribute cleaning media to the outside environment of the air chamber compartment. For this purpose, the discharge opening must be gas-tight from the outside environment. This can be achieved, for example, by means of a device such as a siphon, a valve, or a container to be emptied. In the area of ​​the lowest point of the base, a discharge opening may be in the base, but also in the wall of the air chamber compartment near the base. This is possible because in the case of the discharge opening in the wall, there is no accumulation of the cleaning media, and it is possible for it to flow without delay through the discharge opening. Petition 870260051443, dated 05 / 28 / 2026, page 11 / 54 7 / 16

[034] Preferably, through the discharge opening, the cleaning medium used can be removed simply and quickly from the air chamber compartment.

[035] Preferably, an internal space of the hygienic compartment can be placed under overpressure or vacuum and / or under a protective gas atmosphere.

[036] In this way, the number of germs in the internal space of the hygienic compartment can be reduced, so that both the filling and closing of the cans can occur under hygienic conditions, and the shelf life of the filling material can be extended. The number of germs can be reduced, for example, by means of a cleaning device placed in the hygienic compartment, in order to reduce a renewed increase in the number of germs by means of overpressure or vacuum and / or in the atmosphere of a protective gas. The cleaning device may comprise gaseous, liquid or solid cleaning means, particle radiation or electromagnetic radiation or a mechanical device. Mechanical devices may be brushes, sponges, scrapers, etc.

[037] Preferably, a can can be inserted fully or partially into the hygienic compartment. If it is inserted only partially, then the hygienic compartment has at least one sealing element to seal the hygienic compartment against the can in the hygienic compartment.

[038] The advantage is that the execution of the hygienic compartment can be adapted to individual needs.

[039] Preferably, a lid alignment device for aligning a can lid is integrated or can be integrated into the hygienic compartment. The lid alignment device comprises one or more sensors and a lid rotation device and / or a can rotation device. The device Petition 870260051443, dated 05 / 28 / 2026, page 12 / 54 8 / 16 lid alignment, but may also include one or more sensors and a lid rotation device and a can rotation device.

[040] The sensors can be optical or mechanical sensors, they can recognize markings on the can or can lid. The markings can be: colors, inscriptions, shapes, codes, images, surface protrusions or arrangements such as can opening devices, etc. If a marking is recognized by means of the sensor, then by means of the control the lid rotation device performs a corresponding rotation of the lid and / or can, until the predefined appearance is obtained.

[041] The advantage of an integrated or integrable lid alignment device lies in the fact that during the filling process an alignment between the lid and the can can occur, so that a unified appearance of all closed cans is generated. With the aid of this device, an additional process step can be saved and processing time and processing costs can be reduced.

[042] Furthermore, the task is solved by a method for filling and closing cans under hygienic conditions, in particular, with a machine as described above.

[043] The method comprises the following steps: a) sealing a can inside a hygienic compartment; b) filling the can; c) placing a lid on the can; d) releasing the can from the hygienic compartment.

[044] In this case, the lid can be inserted into the hygienic compartment before, during or after step b).

[045] If the lid is inserted into the hygienic compartment before Petition 870260051443, dated 05 / 28 / 2026, page 13 / 54 9 / 16 of step b), then it can be introduced separately from the can before, during or after the can is placed in the hygienic compartment. However, it can also be introduced together with the can, for example, by placing the can in the hygienic compartment.

[046] The advantage of the method lies in the fact that it allows the can to be filled and closed under hygienic conditions in a very efficient time.

[047] In the method, the cap insertion step preferably comprises the following partial steps: - inserting a can lid into an inner tube compartment, - Cleaning the lid of the can in the inner tube compartment, - Closing the can lid in the hygienic compartment.

[048] The advantage of the method lies in the fact that the preparation of the can lid for hygienic closure of the can occurs in parallel with the can filling process. In this way, time and costs can be saved.

[049] Furthermore, the task is solved by means of a lid-placing device for filling the can. The lid-placing device comprises a lid-carrying device, a tamping arrangement, and a splicing device. In addition, the lid-placing device may also comprise a lid-carrying device and a tamping arrangement, or a lid-carrying device and a splicing device. The lid-placing device is characterized by the fact that it can be introduced into a hygienic compartment. Furthermore, it is designed in such a way that it can be introduced into a machine for filling and closing cans under conditions Petition 870260051443, dated 05 / 28 / 2026, page 14 / 54 10 / 16 hygienic. At the same time, it can be moved along with the can that is in the machine.

[050] The advantage of the lid placement device is that it can be introduced into an existing can filling machine. In this way, a can filling machine can be expanded into a machine that, in addition, places can lids on the can under hygienic conditions and, depending on the equipment, also closes immediately. In this case, time and costs are saved.
