Description

Technical Field

[0001] The present invention relates to a system for filling and sealing cans under hygienic conditions according to the preamble of the independent claim. Background Art

[0002] In the prior art, there are known various systems for filling and / or sealing containers. The purpose of these systems is to automatically fill and seal a large number of containers. A particular challenge is to fill and seal cans with a robust and safe system in the shortest possible time and under the most hygienic conditions.

[0003] From the patent document WO 2011 / 029609, there is known a system for aseptically filling products, especially beverages, into bottles or similar containers. For this purpose, the containers are placed in a housing that forms a sterile space. The housing includes both means for filling the containers and means for sealing the containers. In a first step, the containers are filled with the corresponding beverage, and then in a second step, they are transferred by a container transfer device to the means for sealing the containers. This operation requires a large amount of time and a great deal of effort and high costs to convert the corresponding space into a sterile environment.

[0004] Furthermore, the document DE 19739326 describes a device for processing beverage containers, which closes the beverage containers in a housing under aseptic conditions during processing. For this purpose, the beverage containers located on a conveyor belt are separated from each other by doors. When the beverage containers are introduced into the device, these doors form a closed space under aseptic conditions. A disadvantage of this device is that the conveyor belt must stop during processing.

[0005] DE 4424098 discloses a device for sealing containers. During the movement of the container along a conveying path, a sealing cap is moved towards the container mouth, and an entry gap is formed between the container mouth and the sealing cap. This entry gap forms a processing zone. In the processing zone, before the sealing process, aseptic treatment is carried out in the area of the container mouth. In this case, only the sealing process of the container is carried out in a sterilized state. The disadvantage of this is that the overall degree of sterilization during the filling process is not particularly high, and the shelf life of the filled material may not be long.

[0006] US 2695743A describes a machine for filling a container with a liquid under backpressure conditions. The machine includes a filling head and a chamber, the open end of which houses the container. The backpressure is generated by compressed gas, which also supports the operation of the valve in the filling head, while measures are taken to sterilize the bottle stopper or other seal. The seal and the container remain in a sterile environment until the end of the sealing process.

[0007] It is known from US 3356510A that there is a device for closing a liquid container. For this purpose, the chamber at least receives a part of the open end of the container and fills the container with the corresponding liquid under backpressure. Then, the container is sealed with a lid using a closing head located in the chamber.

[0008] US 2885845A describes a device for sterilizing and sealing a container under aseptic conditions. For this purpose, a cylinder with an open bottom is used to seal with a liftable platform. The sealed space is first sterilized with hot gas, and then the required filling is poured into the container from a reservoir. Then, a pressing joint is lowered into the closed container to seal the container. The filled and sealed container is then removed at a discharging station.

[0009] US 2972214A discloses a system for aseptically sealing bottles and other containers filled with sterilized liquid.

[0010] EP3757024 shows a device for filling and sealing cans under hygienic conditions. Summary of the Invention

[0011] The object of the present invention is to provide a system for filling and sealing cans that can avoid the disadvantages of the prior art or improve the prior art. In particular, a reliable and easy-to-use system and method are provided that can fill and seal beverage cans in the shortest possible time and under the highest hygienic conditions.

[0012] This object is achieved by a system for filling and sealing cans according to the independent claims.

[0013] According to the present invention, a system for filling and sealing cans under hygienic conditions includes a hygienic chamber and an inlet opening for the filling material, which is formed on the hygienic chamber. During normal use, one or more cans are assigned to the hygienic chamber so that the hygienic chamber can move in the system together with one or more of the cans.

[0014] According to a first embodiment of the present invention, a seaming device is provided in the hygienic chamber. The seaming device includes a lid holder and a seaming roller. A filling tube can pass through the lid holder to fill the can, especially the filling tube has passed through the lid holder.

[0015] In this case, sealing the can means at least placing the can lid on the can. By pressing the lid onto the can or connecting the can lid to the can by a common connection technique (preferably by seaming), it can be ensured that the can remains sealed for further processing.

[0016] In this system, the cans to be filled and sealed are cans filled with liquid and / or solid filling materials. Preferably, these are beverage cans filled with liquid materials, especially beverages.

[0017] A hygienic compartment is defined herein as a space that is enclosed from the environment and is under hygienic conditions. Hygienic conditions are understood herein to be at least in accordance with the conditions of hygiene class I as defined according to the German Engineering Federation (VDMA) standard (No. 2 / 2000, 3rd edition 2016). Preferably, the hygienic conditions are in accordance with hygiene class III or higher as defined according to the German Engineering Federation (VDMA) standard (No. 2 / 2000, 2016 3rd edition).

[0018] The lid holder can pick up the lid by means of a receiving mechanism and convey the lid into the can. The receiving mechanism can be a suction mechanism, a magnetic mechanism or a guiding mechanism through which the lid moves.

[0019] The advantage of this system is that the can can be filled and sealed in such a way that the material in the can has a long storage time and at the same time the filling and sealing process can be very efficient. In addition, under such conditions, it is possible to optimize the pressure ratio so that even when using foaming substances and dusty substances, rapid filling and sealing can be achieved. The system uses an overpressure of up to 65 bar (bar), preferably between 0 - 40 bar. The system is also very robust and easy to apply.

[0020] Preferably, the filling tube is movably arranged in the seaming device, especially in the lid holder.

[0021] This has the advantage of an economical and space-saving system configuration, and at the same time allows for rapid filling and subsequent cleaning of the filling tube, thus creating optimized hygienic conditions.

[0022] Preferably, the filling tube includes a flow diversion mechanism located in the end region at the outlet of the filling tube. The flow diversion mechanism is a mechanism that can separate the filling material flow and ensure that the filling material presents a laminar flow state with less turbulence.

[0023] The flow diversion mechanism can be: grids of different designs, several substantially parallel pipes, rotating elements such as rotors, pumps, vanes, etc.

[0024] In this case, a laminar flow with less turbulence means that the foam generated by the liquid will be especially reduced to a minimum.

[0025] The advantage of such a flow diversion mechanism is that the product is in a laminar flow state, thus avoiding the turbulence that may slow down the filling speed, cause the filling material to foam (such as beer), and additionally contaminate the hygienic compartment due to the filling material splashing out of the can and resulting in the need for additional cleaning steps.

[0026] The flow diversion mechanism is preferably designed as a static flow diversion mechanism. Pipes or grids are particularly suitable as static flow diversion mechanisms.

[0027] The advantages of the static flow diversion mechanism are that the components are simple, the installation is convenient, and the maintenance is convenient.

[0028] Preferably, the flow diversion mechanism is designed as an adjustable flow diversion mechanism. The rotor, vane or pump is particularly suitable for this purpose.

[0029] The advantage of the adjustable flow diversion mechanism is that they can quickly and continuously convert the existing turbulent flow into laminar flow.

[0030] Preferably, the filling pipe includes one or more shut-off mechanisms and / or metering mechanisms.

[0031] The shut-off mechanism and / or metering mechanism can form different designs with different functions. The shut-off mechanism and / or metering mechanism can in particular be a valve.

[0032] The advantage of the filling pipe with a shut-off mechanism is that the shut-off mechanism adjusts the flow rate of the filling material in the filling pipe.

[0033] Preferably, during normal use, one of the shut-off mechanisms is arranged at the end of the filling pipe facing the tank in order to open and close the filling pipe.

[0034] Additional shut-off mechanisms can be used to select whether the filling material, cleaning liquid, inert gas (such as inert gas, to a certain extent also including carbon dioxide (CO 2 ) or nitrogen (N 2 ) etc.) passes through the filling pipe. After filling the tank, the filling pipe can be purged to remove any residual liquid, thereby ensuring that almost all of the residual liquid enters the tank. If the shut-off mechanism is located at the lower end of the filling pipe, there is no need to forcefully purge the filling pipe.

[0035] The shut-off mechanism for opening or closing can be a pressure reducing valve, pressure control valve, on-off valve, load holding valve, gate valve, butterfly valve, ball valve, etc.

[0036] The advantage of such a shut-off mechanism is that it can regulate whether the product flows into the tank. This can prevent the tank from overflowing.

[0037] Preferably, the filling pipe includes one or more shut-off mechanisms or feeding elements. In this case, during normal use, one of the shut-off mechanisms or feeding elements is arranged at the end of the filling pipe facing away from the tank in order to open and close the filling pipe.

[0038] The shut-off mechanism for opening or closing can be a pressure relief valve, pressure control valve, on-off valve, load holding valve, etc. For example, the feeding element can be a hose, pipe, pipeline, screw feeder, etc.

[0039] The advantage of such a shut-off mechanism or feeding element is that it can regulate whether, how fast and how much filling material can flow into the filling pipe.

[0040] Preferably, the shut-off mechanism or the feed member is arranged at the end of the filling pipe facing away from the tank and, in normal use, can introduce solids (such as powders), liquids and / or gases. The solids, liquids and / or gases are in particular filling materials, cleaning agents or disinfectants.

[0041] Examples of filling materials are beverages, CO 2 , N 2 , protective gases (such as noble gases), etc. Examples of cleaning agents are liquid cleaning agents, inert gases, water vapor, acids, alkalis, disinfectants, foaming agents, etc. The liquid can be introduced at a temperature below 15 °C to close to the freezing point of the liquid or at a temperature up to the boiling point of the liquid (such as water vapor up to 200 °C).

[0042] In fact, it is particularly advantageous that the shut-off mechanism or the feed member is formed to be able to introduce liquids and / or gases, in particular filling materials or cleaning agents, because in this way the tank can be filled under optimal hygienic conditions.

[0043] Preferably, the filling pipe includes a filling pipe side wall, which in turn includes an inner filling pipe wall, an outer filling pipe wall and at least one hole, and the at least one hole is provided on the filling pipe side wall. The provision of at least one hole in the filling pipe side wall enables the outer wall of the filling pipe to be flushed with gas and / or liquid, in particular cleaning liquid. When open, the at least one hole serves as an outlet for the media (gas, liquid) introduced into the filling pipe, which are used for purging, cleaning and disinfecting. If the hole is in the closed state, the filling material can be fed through the filling pipe without contacting the outer wall of the filling pipe.

[0044] The gases used are CO 2 , N 2 , inert gases (such as noble gases), water vapor, etc. The cleaning liquid can be an acid, an alkali, water or a disinfectant, which can remove the filling material and impurities and / or kill bacteria, viruses, fungi, etc. without leaving any residue.

[0045] Such an arrangement is particularly advantageous because the hygienic conditions can be optimized by cleaning the outer wall of the filling pipe with gas and / or cleaning liquid.

[0046] Preferably, the hygienic compartment includes a cover slide.

[0047] The cover slide can be provided with a sliding and / or latching mechanism.

[0048] The advantage of arranging the cover slide in the hygienic compartment is that the cover slide has one or more covers, enabling automatic and thus efficient and rapid cover delivery.

[0049] According to another aspect, a system for filling and sealing cans under hygienic conditions, as described above, further has a seaming device adjustment mechanism. The seaming device adjustment mechanism is used to adjust the seaming rollers and / or replace the seaming chucks. The seaming device adjustment mechanism is arranged outside the hygienic compartment and is in the form of a centrifugal screw, a slide rail, a screw, etc.

[0050] The setting of the seaming rollers and / or the replacement of the seaming chucks vary with the size and shape of the cans to be filled, especially with the size of the can lids and the shape of the can lids. Therefore, when changing the size or shape of the cans, it is necessary to make corresponding adjustments to these.

[0051] It is particularly advantageous if the seaming device adjustment mechanism is arranged outside the hygienic compartment. In this way, the seaming device can be adjusted more conveniently and a large amount of time is also saved.

[0052] Preferably, tools or other auxiliary mechanisms are used to further operate the seaming device in the hygienic compartment, which is formed so that it can be interlocked into the grooves on the seaming rollers.

[0053] According to an alternative design of the device of the present invention, a platform for placing cans is arranged in the hygienic compartment. During normal use, the platform with the cans can be lifted towards the inlet opening of the filling material. The hygienic compartment also includes a casing and end plates arranged around the platform. In order to be able to seal the hygienic compartment, the casing can be lifted towards the inlet opening until it reaches the end plates, or the casing can be attached to the end plates in such a way that the platform is lifted inside the casing.

[0054] According to an alternative design of the system of the present invention, obviously but not necessarily, it further includes a seaming device arranged on the hygienic compartment, and the seaming device includes a lid holder and seaming rollers, wherein the filling pipe can pass through the lid holder to fill the cans, especially the filling pipe has passed through the lid holder.

[0055] In this case, sealing the cans means at least placing the can lids on the cans. By pressing the lids on the cans or connecting the can lids to the cans through common connection techniques (preferably by seaming), it can be ensured that the cans remain in a sealed state for further processing.

[0056] In this system, the cans to be filled and sealed are cans filled with liquid and / or solid filling materials. Preferably, these are beverage cans filled with liquid filling materials, especially beverages.

[0057] A hygienic compartment is defined here as a space that is isolated from the surrounding environment and maintained under hygienic conditions. Hygienic conditions are understood here to be at least in accordance with the hygienic class I defined according to the standards of the German Engineering Federation (VDMA) (No. 2 / 2000, 3rd edition 2016). Preferably, the hygienic conditions are in accordance with the hygienic class III or higher defined according to the standards of the German Engineering Federation (VDMA) (No. 2 / 2000, 3rd edition 2016).

[0058] The lid holder is able to pick up the lid by means of a receiving mechanism and convey the lid into the can. The receiving mechanism can be a suction mechanism, a magnetic mechanism or a guiding mechanism through which the lid moves.

[0059] The platform can be solid, in the form of a plunger, but can also be in the form of a lifting rod with a plate at the upper end of the lifting rod.

[0060] The advantage of this system is that the can can be filled and sealed in such a way that the material in the can has a long storage time and at the same time the filling and sealing process is very efficient. In addition, under such conditions, it is allowed to optimize the pressure ratio so that even when using foaming substances and dusty substances, rapid filling and sealing can be achieved. The system uses an overpressure of up to 65 bar, preferably between 0 - 40 bar. The system is also very reliable and easy to apply.

[0061] Preferably, the cladding is hollow cylindrical. The advantage of this is that on the one hand, the material cost is reduced, and on the other hand, the installation space of the system can also be saved.

[0062] Preferably, the platform has a concave bend for can alignment.

[0063] The advantage of the concave - bent platform is the stable standing of the can, preventing the can from sliding.

[0064] Preferably, the cladding can form a sealing stop against the end plate.

[0065] This can improve the hygienic conditions for filling and sealing the can.

[0066] According to another aspect, as described above, a system for filling and sealing cans under hygienic conditions further includes a storage compartment for storing at least one lid, preferably a stack of at least two lids. The storage compartment is arranged next to the hygienic compartment. However, particularly, the storage compartment can also be arranged on the hygienic compartment.

[0067] The advantage of such a storage compartment is that the lids are available for sealing the cans and are automatically transferred from the storage compartment to the cans.

[0068] Preferably, the lid in the sealed hygienic compartment can be moved from a position adjacent to the can to a position above the filling can, in particular, it can be pushed, pulled or rotated by means of a moving device.

[0069] Feeding the lid onto the can in this way is particularly advantageous as it enables the lid to be automatically fed onto the can, thus not only ensuring that the can can be easily sealed, but also optimizing the compliance with hygienic conditions during the sealing process.

[0070] Preferably, the hygienic compartment is equipped with a cladding and end plates, the cladding being arranged around the platform and allowing the hygienic compartment to be sealed, wherein the cladding can be lifted towards the access opening to seal the hygienic compartment, and the storage compartment is provided on the cladding. The storage compartment stores at least one lid, preferably a stack of at least two lids. The cladding and the storage compartment provided thereon can form a sealing stop against a stop plate, in particular can be lifted.

[0071] This improves the hygienic conditions during the can sealing process.

[0072] Preferably, the storage compartment further comprises a feed opening, in particular a nozzle for supplying a cleaning agent or gas; and an outlet for discharging liquid, in particular a discharge valve for gas.

[0073] The feed opening is used to allow the cleaning agent to enter from the storage compartment. In order to maintain hygienic conditions, the feed opening must be hermetically sealed from the external environment of the storage compartment. For example, the feed opening can be an inlet or a nozzle. On the other hand, the outlet is used to discharge the cleaning agent to the external environment of the storage compartment, so it must be hermetically sealed from the external environment of the storage compartment. This can be achieved by means such as a siphon, a valve or a container to be emptied.

[0074] The advantage is that the can lids are cleaned in the storage compartment, thus optimizing the hygienic conditions of the can lids before they are applied to the filled cans.

[0075] Preferably, the storage compartment further comprises a lid separating mechanism, which in turn comprises a stack of can lids, a drawer and a slide plate for separating the can lids.

[0076] The advantage of such a lid separating mechanism is that the storage compartment can store a large number of lids, and then the lids can be quickly and automatically transported onto the filled cans for sealing.

[0077] According to another aspect, as described above, the system for filling and sealing cans under hygienic conditions further comprises feeding means for feeding the cans to be filled and / or conveying means for conveying the filled and sealed cans.

[0078] The cans and lids are picked up in the feeding means by means of a carrier. For example, the carrier can be in the form of an active or passive gripper. The picking up can be carried out radially or linearly.

[0079] This makes it possible to quickly fill and seal a large number of cans.

[0080] Preferably, the feeding device and / or the conveying device further comprise at least one conveyor belt for conveying empty cans or filled cans, and a can stopping device, which successively comprises at least two expandable stoppers. At least one expandable stopper is arranged on one side of the conveyor belt, and at least one expandable stopper is arranged on the opposite side of the conveyor belt. In the expanded state, the expandable stopper stops the cans on the conveyor belt. In the non-expanded state, the expandable stopper allows the cans to pass through.

[0081] The expandable stopper is a hollow body made of an elastic material. When the internal pressure of the hollow body increases, it expands, and when the internal pressure decreases, the hollow body returns to its original shape. At the same time, the elastic material has sufficient stability to be arranged upright on both sides of the conveyor belt without expanding.

[0082] The expandable stopper enables the cans to stop on the conveyor belt in a gentle and reliable manner, thereby preventing damage to the cans on the one hand, while ensuring the continuous stopping and movement of the conveyor belt and / or the conveyed cans.

[0083] According to another aspect, as described above, a system for filling and sealing cans under hygienic conditions further comprises a seaming device, as described above, which comprises a filling tube for filling the cans and at least one unit for sealing the cans. According to the position of the filling tube, the seaming device is arranged above or below the inlet opening.

[0084] The lowerable filling tube can be used as the filling tube for internal injection filling, but the filling tube can also be designed to enable edge filling, and in special cases, the lowering of the filling tube during the filling process can be omitted.

[0085] The advantage of this is that cans can be efficiently filled and sealed in a hygienic compartment.

[0086] This object can also be achieved by a method for conveying the cans to be filled to the filling position in the above-mentioned system. The method comprises the following steps:

[0087] i) Placing the cans on the platform;

[0088] ii) Sealing the hygienic compartment and moving the cans to the filling position, which is achieved by

[0089] a1) Lifting the cladding; and

[0090] a2) Lifting the platform;

[0091] or

[0092] b) Lifting the platform into the cladding.

[0093] Steps a1) and a2) can be carried out sequentially, partially overlapping, or simultaneously. It is also possible to carry them out in the reverse order, i.e., a2) completely before a1); or a2) partially or completely overlapping with a1).

[0094] The advantage of this method is that it ensures optimal hygienic conditions. This method is also very reliable and easy to use.

[0095] This object is also achieved by a method for separating lids in the above-mentioned system. The method comprises the following steps:

[0096] a) Place a stack of at least two can lids in the storage compartment on the drawer;

[0097] b) Separate the bottom can lid from the upper can lid using a slide plate;

[0098] c) Move the drawer horizontally so that the bottom can lid drops downwards;

[0099] d) Move the drawer to the starting position so that the bottom can lid drops onto the feeding support;

[0100] f) Place the bottom can lid on the filled can using a moving device.

[0101] The bottom of the storage compartment, the carrier, part of the feeding or conveying device, or has holes that only allow the can lids to drop.

[0102] One advantage of this method is that the sealing speed of the filled cans is accelerated and the separation of the lids is automatic.

[0103] This object is also achieved by a method for feeding and discharging cans and can lids using the feeding device or conveying device in the above-mentioned system. The method comprises the following steps:

[0104] a) Receive the cans and can lids into the feeding device simultaneously or sequentially;

[0105] b) Rotationally move the cans to the hygienic compartment and rotationally transfer the can lids to the storage compartment simultaneously or sequentially;

[0106] c) Fill the cans;

[0107] d) Linearly or rotationally move the can lids and place them on the filled cans;

[0108] e) Seal the filled cans with the can lids;

[0109] f) Linearly or rotationally move the filled and sealed cans to the discharging position;

[0110] g) Discharge the filled and sealed cans.

[0111] The advantage of this method is that a large number of cans can be quickly filled and sealed. BRIEF DESCRIPTION OF THE DRAWINGS

[0150] Figure 1 Shows a cap holder 71 and a filling pipe 73 of the system 1 that are part of a seaming device 7. The filling pipe 73 is used for automatic filling and sealing of a can 2. The function of the filling pipe 73 is to fill the can 2 (not shown) with material. The filling pipe 73 passes through the cap holder 71 and can be arranged movably or immovably within the cap holder 71.

[0151] Figures 1a to 1c Shows different embodiments of the filling pipe 73.

[0152] Figure 1a Displays a filling pipe 73 having a shut-off mechanism 732. During normal use, the shut-off mechanism 732 is provided at the end of the filling pipe 73 facing the can 2. The shut-off mechanism 732 can move vertically to open or close the filling pipe 732 and adjust whether to fill the can 2 with filling material. The shut-off mechanism 732 actively rises or falls from the end of the filling pipe 73 facing the can 2 during normal use, and opens or seals the filling pipe 73 through a seal 7341a provided on the inner side wall 7341 of the filling pipe. As shown in the figure, the shut-off mechanism 732 can form various shapes, such as conical, trapezoidal, etc. The shut-off mechanism 732 can also be driven by spring force or the pressure difference between the inner side wall 7341 of the filling pipe and the sanitary compartment 3. In this way, there is no need to open and close the shut-off mechanism 732 through an external mechanical connection.

[0153] Figure 1b Shows another embodiment of the filling pipe 73. Here, the filling pipe 73 also includes a shut-off mechanism 732. During normal use, the shut-off mechanism 732 is provided at the end of the filling pipe 73 facing the can 2. The shut-off mechanism 732 can move vertically and is also used to open or close the filling pipe 732 and adjust the amount of filling material entering the can 2. During normal use, the shut-off mechanism 732 rises or falls to open or close one end of the filling pipe 73 facing the can 2.

[0154] Figure 1c Shows another embodiment of the filling pipe 73. During normal use, a flow diversion mechanism 731 is shown at the end of the filling pipe 73 facing the can 2. The function of the flow diversion mechanism 731 is to convert the turbulent flow of the filling material into laminar flow, so as to minimize splashing and / or foaming as much as possible when filling the can 2 with the filling material. This is a static flow diversion mechanism 731.

[0155] Figure 1d Another embodiment of the filling tube 73 is shown. Here, the filling tube 73 also includes a static flow diversion mechanism 731, which is composed of several tubes with a diameter smaller than that of the filling tube 731.

[0156] Figure 2 、 Figure 3 、 Figure 4 、Figure 5, Figure 5, Figure 5, Figure 5, Figure 5, Figure 6 and Figure 7 show different embodiments of the system 1, where the seaming rollers are located outside the hygienic compartment 3.

[0157] Figure 2 The first embodiment of the system 1 is shown, including a hygienic compartment 3, a seaming device 7 and a seal 32, and the seal 32 seals the hygienic compartment from above when the hygienic compartment is in the closed state. In addition, a lifting mechanism (not shown here or below) can be provided for lifting and lowering the can 2. The seaming device 7 includes a lid holder 71 and seaming rollers 72. The lid holder 71 is located inside the hygienic compartment 3. During the preparation for the seaming process, the lid holder with the lid can be lowered onto the can; and / or the can can be lifted towards the lid holder by the lifting mechanism (this also applies to the embodiments shown in Figures 3 to 7 ). The seaming rollers 72 are located outside the hygienic compartment 3. The lid holder 71 includes a filling tube 73, and the filling tube 73 can pass through the lid holder 71 through the access opening 30. The can 2 and the can lid 21 are arranged inside the hygienic compartment 3, and the can lid 21 is located on the support 33 above the opening of the can 2. In this case, the seal 32 is a tenon joint seal. The hygienic compartment 3 is opened, and the can 2 is filled and sealed with the filling material. Since the seaming rollers 72 are arranged outside the hygienic compartment 3, the wear generated during the seaming process causes less pollution to the hygienic compartment 3. Figures 3 to 7 ).

[0158] Figure 3 The second embodiment of the system 1 is shown. Figure 3 The embodiment shown in Figure 2 corresponds to the embodiment shown in Figure 2 , but different from the first embodiment shown in

[0159] Figure 4 , it has a horizontal seal 32 and a support 33, and the support 33 is arranged inside the hygienic compartment 3.

[0159] Figure 4 The third embodiment of the system 1 is shown. This system 1 is similar to the system 1 shown in Figure 2 . Here, a tenon joint seal 32 for sealing the hygienic compartment 3 is also provided. Different from the system 1 shown in Figure 2 , Figure 4Also shown is a lid slide 34, which is arranged on an upper attachment (not shown) of the sanitary compartment. Preferably, in the present embodiment, the lid slide 34 is arranged in a vertically fixed position.

[0160] Figure 5a and Figure 5b The sanitary compartment 3 of the system 1 is shown. The sanitary compartment 3 is sealed by a horizontal seal 32. A can 2 and a can lid 21 are arranged inside the sanitary compartment 3. The lid slide 34 is integrated into the wall of the sanitary compartment 3. By a push or pull movement initiated from the outside, the lid slide 34 moves the can lid 21 onto the can 2.

[0161] Figure 6 Shows a similar Figure 3 Another embodiment of the system 1 is shown. In addition, a lid slide 34 and a lid pressing device 35 are also shown here. The lid slide 34 is actuated from the outside to move the can lid 21 onto the can 2. The lid pressing device 35 presses down the can lid 21, thereby reducing the internal volume of the sanitary compartment 3. The resulting smaller internal volume of the sanitary compartment 3 means that any flushing process using cleaning agents, disinfectants, protective gases, etc. can be carried out more economically, efficiently, and quickly.

[0162] Figure 7 A lid pressing device 35 in another embodiment is shown. Contrary to the variant shown in Figure 6 An arm 351 is provided on the lid pressing device 35, which can move the can lid 21 onto the can. The advantage of this arrangement is that the lid slide does not have to move with the casing.

[0163] Figure 8a , Figure 8b , Figure 9a , Figure 9b , Figure 9c Schematically shows the opening of the sanitary compartment 3, and the can 2 and the can lid 21 are sealed by means of double seaming.

[0164] Figure 8a Shown is the sealed sanitary compartment 3 with a filled can 2 having a can lid 21 thereon.

[0165] Figure 8b Shows the sanitary compartment 3 in the open state and how the can 2 with the can lid 21 is sealed by means of two double seaming rollers 72. The open sanitary compartment 3 makes way for the double seaming rollers 72 so that the can lid 21 and the can 2 are interlocked by means of double seaming.

[0166] Figure 9a and Figure 9b Shows in more detail the sealing of the sanitary compartment 3 for filling the can 2, the opening of the sanitary compartment 3, and the process of sealing the can 2 with the can lid 21. Figure 9aAfter the sanitary compartment 3 in it is sealed, the overpressure generated by the gas presses the seal 36 against the inner wall of the sanitary compartment 3.

[0167] Figure 9c Shown from the side Figure 9a and Figure 9b the arrangement of the roll seamer 72 in

[0168] Figure 10a and Figure 10b shows the flushing process of the outer wall 7342 of the filling tube 73 that can move in the cap holder 71. The filling tube includes a filling tube side wall 734, and the filling tube side wall 734 successively includes the inner wall 7341 of the filling tube, the outer wall 7342 of the filling tube, and the hole 7343. The filling tube side wall 734 may also include a plurality of holes 7343 instead of one hole 7343. A cavity 712 is located between the filling tube 73, the cap holder 71, and the seal 711. If the filling tube is now vertically moved in the cap holder 71 such that the hole 7343 on the filling tube side wall 7342 is located in the area between the seals 711, as Figure 10b shown, then the flushing process can be started. The cavity 712 is filled with a cleaning agent, a disinfectant, a protective gas, etc., and then sent into the filling tube 73 through the hole 7343 and flows out.

[0169] Figure 11 The system 1 shown is used for the automatic filling and sealing of the can 2. The system 1 includes a sanitary compartment 3, a platform 31 on which the can 2 can be placed (not shown here, see Figure 2 ), a casing 32, and an end plate 33. In the first step, the platform 31 lifts the can 2 and moves it in the direction of the end plate 33. This action is used to position the can 2 to the horizontal position required for the subsequent filling process. This step can also be omitted in a special arrangement. In the second step, the casing 32 arranged around the platform 31 also moves in the direction of the end plate 33 until the casing 32 stops to form a sealing stop against the end plate 33. The above two steps can also be carried out in the reverse order or simultaneously.

[0170] Figure 12 shows a further embodiment of the system 1 for the automatic filling and sealing of the can 2. Here it is shown how the can 2 moves on the platform 31 with a concave bend in the direction of the end plate 33 (not shown here, see Figure 11 ) until the can 2 reaches the sealing stop against the end plate 33. In the second step, the filling material is then filled into the can 2 through the feed port 30 integrated in the end plate 33.

[0171] In Figure 13In it, the storage compartment 5 integrated in the system 1 is shown. The storage compartment 5 is arranged on the sanitary compartment 3 and stores the can lids 21. In the first step, the can 2 is moved on the platform 31 in the direction of the end plate 33. In the second step, the housing 32 provided with the storage compartment 5 follows until it stops against the end plate 33. Then the can 2 is filled with the filling material (see Figure 12 ). Subsequently, the can lid 21 in the storage compartment 5 is moved into the sanitary compartment 3 and placed on the filled can 2.

[0172] Figure 14 The lid separating mechanism 52 integrated in the storage compartment 5 is shown, including a stack of can lids 21, a drawer 521, a slider 522 for separating the can lids 21, and a moving device 50, where the stacked can lids 21 are located on the drawer 521. In step A, the stacked can lids 21 are separated from the bottom can lid 21 using the slider 522. In step B, the drawer 521 is moved horizontally away, causing the bottom can lid 21 to drop down. In step C, the drawer 521 moves back to the starting position, causing the bottom can lid 21 to drop onto the feeding support 523, which is in the form of the base of the storage compartment 5 in this example. Then in step D, the can lid 21 is placed on the filled can 2 or returned to the feeding support 523 by the moving device 50.

[0173] Figure 15 , Figure 16 , Figure 17 and Figure 18 Different design variants of the feeding device 6 and the conveying device 6a are shown.

[0174] Figure 15 The feeding device 6 with two rotationally symmetric carriers 64 is shown. In step A, one of the two carriers 64 on one side picks up the can 2, while the other three carriers 64 remain empty. In step B, the feeding device rotates 90° and moves the can 2 accordingly. In step C, the can end 21 is picked up in the second carrier 64 on the same side. This carrier 64 can also serve as the feeding support 523 of the lid separating mechanism, as shown in Figure 14As shown. In step D, the feeding device 6 rotates by 90° again and moves the can 2 and the can lid 21 accordingly. Here, the can 2 is placed on the platform 31 and the can lid 21 is placed on the can lid holder 53. In step E, the feeding device 6 rotates 90° in the reverse direction while the can 2 and the can lid 21 remain stationary and are held on the platform 31 and the can lid support 53. At this time, the can 2 has been filled with the filling material. In a further step, the can lid 21 is pushed onto the filled can 2 and the can 2 is sealed. In step F, the feeding device rotates 90° again in the initial direction and one of the two carriers 64 receives the filled can 21 on one side again. On the other side, the other carrier 64 picks up another unfilled can 2. In step G, the feeding device 6 is rotated by 90° again and the carrier 64 that is still idle on the side of the unfilled can 2 receives another can lid 21. After rotating by 90° again in step H, the filled can 2 is sent out, for example, dropped through the opening of the workbench. Now, steps D to H are repeated again.

[0175] Figure 16 Another embodiment of the feeding device 6 is shown. The can 2 is in an external position while the can lid 21 is on the feeding device 6, and the can lid 21 moves onto the filled can 2 during a rotational movement after the can 2 has been filled with the filling material. The support surface of the lid 21 on the feeding device 6 can also serve as Figure 14 the feeding support 523 for can lid separation as shown in

[0176] Figure 17 Another embodiment of the feeding device 6 is shown, which is Figure 15 and Figure 16 a combination of the two embodiments in

[0177] Figure 18 An embodiment similar to the feeding device 6 shown in Figure 16 is shown. In addition, a conveyor belt 61 for transporting the empty can 2 to the feeding device 6 and a conveying device 6a for removing the filled and sealed can 2 are also shown. Both the feeding device 6 and the conveying device 6a are in a conveying star structure. The conveying device 6a consists of several units composed of the platform 31 and the can support 53. The platform 31 can accommodate an empty can 2 and a can lid 21 respectively. The can lid 21 is placed on the feeding device 6. After filling and sealing the can 2 with the can lid 21, the filled can 2 is guided away by the conveying device 6a. In this case, the contact surface of the can lid 21 on the feeding device 6 can also be used as Figure 14 the feeding support member 523 for can lid separation as shown in

[0178] Figure 19An apparatus 62 for stopping cans 2 on a conveyor belt 61 is shown. The can-stopping apparatus 62 has two expandable hollow cylindrical stoppers 63 on opposite sides of the conveyor belt 61. To stop the cans 2 on the conveyor belt 61, the expandable hollow cylindrical stoppers 63 are inflated with a gas (such as air). By narrowing the passage between the two expandable hollow cylindrical stoppers 63, the cans 2 are gently blocked. After the gas is released, the passage between the two expandable hollow cylindrical stoppers 63 is passable again, and the cans are further conveyed on the conveyor belt 61. The advantage of this apparatus is that the conveyor belt 61 can continue to run, and at the required moment, the cans can still be stopped and conveyed again.

[0179] Figures 20a to 20f A compact and force-optimized lifting mechanism 8 for lifting cans 2 for filling and sealing with can lids 21 is shown.

[0180] Figure 20a A top view of the lifting mechanism 8 is shown. The lifting mechanism 8 includes two guide rods 81. The can 2 is disposed on a platform 31 between the two guide rods 81. The can lid 21 disposed on the can lid holder 53 is adjacent to the can 2 and in the same plane.

[0182] Figure 20c The lifting mechanism 8 is shown, including guide rods 81, pivot elements 83, and a tether 84 disposed in the guide rods 81. The platform 31 with the can 2 is attached to the pivot element 83. The pivot element 83 and the platform 31 with the can 2 mounted thereon can be pulled up or lowered down by the tether 84.

[0183] Figure 20d The lifting mechanism 8 is shown, including guide rods 81, a tether 84, and a gear mechanism 85. The platform 31 with the can 2 is disposed on the gear mechanism 85. The tether 84 is disposed in the guide rods 81. By rotating the connecting rod and the gear mechanism 85, the threaded rod driven by the gear mechanism lifts the platform 31 with the can 2.

[0184] Figure 20e The lifting mechanism 8 is shown, including guide rods 81, a wire 86 disposed in the guide rods 81 and connected to the platform 31, and a spring 87 in contact with the platform 31. The can 2 is located on the platform 31. By the pressure of the spring and the release of the wire 86, the can 2 moves upward. By pulling up the wire 86, the can support 31 is lowered.

[0185] Figure 20fAnother lifting mechanism 8 is shown, which includes two guide rods 81. Two cylinders are arranged in the guide rods 81 and are connected to the platform 31. The tank 2 stands on the platform 31. The two cylinders move the platform 31 with the tank 2 up and down.

[0186] Figure 21a The passive carrier 64 of the feeding device 6 and the conveying device 6a (not shown here) is shown. The passive carrier 64 can function well without control. The carrier 64 is in the form of a gripper and can grip the tank 2. The carrier also includes a spring-controlled articulated mechanism 65. The carrier 64 first picks up the tank 2 and moves it to the sanitary compartment 3. Subsequently, the cladding 32 slides upward over the tank 2 from below. The spring-loaded carrier 64 yields to the cladding 32 passively, and the sanitary compartment 3 is sealed.

[0187] Figure 21b The cam-controlled carrier 64 for the feeding device 6 and the conveying device 6a (not shown here) is shown. The carrier 64 is advantageously controlled by the cladding 32, so no additional drive is required. The carrier 64 again appears in the form of a gripper and is capable of clamping the tank 2 (not shown here). The carrier 64 also includes a spring mechanism 66. The carrier 64 picks up the tank 2 and transports it to the sanitary compartment 3. Subsequently, when the cladding 32 rises, the carrier 64 is pushed to the side above the contour of the cladding 32, and the sanitary compartment 3 is closed. The carrier 64 returns to its starting position by spring force.

[0188] Figure 22 The system 1 is shown, which includes the platform 31, the storage compartment 5, two guide rods 81, and the seaming device 7. The system 1 also includes four wheels 11 for flexible use.
