Description

Equipment for handling and dispensing of bulk, liquid and powder goods

Field of technology

The subject of the invention is a device for handling and dispensing bulk goods placed in capsules, with the minimization of packaging waste.

State of the art

The object of the present invention is a technical solution for the sale of goods which minimizes packaging waste throughout the supply chain. There are currently a number of standards that such a solution must meet. These are requirements for hygienic aspects of handling goods, largely given by current legislation, which mainly concerns food, requirements for economic efficiency of the entire solution and requirements for transparent labeling and registration of transported and sold goods. Last but not least, the solution sought must be scalable in order to have a chance of achieving a global positive impact on the environment. Existing logistics and sales systems are built on primary (consumer) packaging, secondary (handling) packaging such as cardboard boxes, or shrink films and tertiary (transport) packaging such as pallets, containers, fixing foils. These types of packaging are very often disposable and a disproportionate amount of packaging waste is generated per unit of goods.

Some manufacturers seek to reduce the environmental impact of packaging waste by using packaging made from recyclable or compostable materials. However, it turns out that this procedure is not sufficient, as such packaging is disposed of together with other materials and their disposal is therefore possible minimally or not at all.

Other current solutions work with wholesale packaging, from which customers buy so-called unpackaged packaging. These systems do achieve a reduction in the volume of disposable consumer packaging, but at the cost of a significant reduction in shopping comfort and hygienic risks in transport, storage and sale of goods. Any handling of bulk (packaging) goods carries the risk of contamination, deterioration or loss of the goods. Bulk goods are inherently a non-systemic element in established processes for both manufacturers and traders and therefore often incur additional costs, which are reflected in the final price of the products, and mainly do not allow for greater expansion of these systems, ie their scalability.

Returnable packaging systems, such as beer bottle systems, are an inspiring solution. In such a system, no unnecessary packaging waste is generated, as the packaging is reused. The returnable packaging is filled at the manufacturer and is emptied at the customer's place of consumption. The limitations of this system are given by the type of products for which this system is suitable and the requirement that the customer accepts the returnable packaging. The current trend of increasing the volume of beer sales in cans indicates that the customer trend is just the opposite.

The essence of the invention

The present invention relates to a device for handling and dispensing bulk, liquid and powdered goods placed in capsules, with the minimization of packaging waste. The essence of the invention is that the capsule, which is a returnable package circulating between the manufacturer and the seller of goods, is situated in the dispensing device so that its outlet fits into an electronically controlled dispensing valve, which ensures integrated dosing of goods without integrated contamination by the operator or the consumer and handling losses, where the capsule consists of an open body into which the capsule insert with the lower opening with the outlet passage of the inner capsule bag for guiding the goods to the outlet mouth fits. The outlet passage is equipped with a bottom lid for

- 1 CZ 2020- 470 A3 protection of the capsule seal against damage, the capsule body is closed by the upper lid when the insert is inserted from above. The filled inner bag of the capsule is simultaneously inserted into the dispensing valve of the device, adapted to ensure a predefined position of the inner bag, where the lower part of the dispensing valve is connected by a spring-loaded hopper with reduction with bayonet cap, the dispensing valve , provided with a seal around its circumference, and a closable tube resp. trunk with a rim, forming a path for the exit of goods for a predetermined time of exit and the amount of goods, by means of flaps, adjustable by means of an electronic servomechanism.

The flaps can be closed and locked in the closed position while the dispensing valve is inactive. At the ends of the flaps, there are preferably flap extensions to improve the closure of the tube, closing the tube in 2 levels one above the other, which can be made of both hard and flexible material.

A chip, preferably an RFID / NFC chip, may be inserted between the capsule insert and the capsule body to identify the goods in the capsule, or extended information about the goods in the capsule, including information about their origin.

The body of the capsule preferably has a conical shape for stackability.

The device may further comprise a vibrating lever which is mounted on the passage of the inner bag of the capsule to facilitate the release of the goods and their dosing. It may also include a paddle for mounting on an empty capsule and covering the passage when replacing the capsule. The device is preferably adapted for data communication about the required quantity of the given goods from the user application or information or storage system, and thus ensuring the automatic delivery of the goods.

The device includes at least one information display for displaying information about the products in the capsules, including name, manufacturer, composition, shelf life, price, remaining quantity in the capsule or the quantity currently in stock.

It is advantageous that the products (bulk, liquid or powder goods) are distributed in refillable capsules, which are placed directly in stores in modular racks called BMS (described in more detail below). The buyer chooses the goods, their quantity and method of packaging using a mobile application or display on the BMS. For better orientation, the capsules are equipped with so-called product cards, which are hung behind the upper lid of the capsule in its front part. This card contains various basic information about the product (name, composition, allergens, expiration date or price). The rest of the information is available from the mobile application or on the receipt. The cards are also equipped with samples with specific goods that are in the capsule. As a result, shoppers see a real product before they buy it. Shopping can take place in other scenarios than self-service, it can also be completely directed by the staff of a particular store. The customer only needs to choose the desired product, quantity and method of packaging. The purchased goods are immediately packed and ready for collection or delivery at the time of payment.

The advantage is the simplification and improvement of the distribution and sale of unpackaged goods, the system is based on reusable transport capsules and in-store modular racks, which ensure supply chain efficiency and inventory management. The system prevents the generation of packaging waste (precycling) throughout the supply chain, from the manufacturer to the household. Manufacturers supply goods packaged in these capsules, wholesale supplies goods in reusable capsules. Empty capsules are sent to the washing center, empty and cleaned capsules are sent back.

Examples of embodiments of the invention

The presented solution is composed of partial technological elements, the design and construction of which are mutually conditioned and closely related so that together they form a consistent and functional unit. These key elements are the capsule, the dispensing valve and the BMS (bulk modular system) dispensing device. The capsule is de facto a wholesale returnable packaging in which the manufacturer packs the goods and which circulates in a closed system between the manufacturer and the seller. At the seller, the capsule is placed in a dispensing device, where its outlet functionally fits into an electronically controlled dispensing valve, which uses integrated scales to ensure accurate dosing of goods without the possibility of contamination of goods by the operator or customer and without unnecessary handling losses.

The capsule consists of two layers. The outer layer (capsule body J) has the following key properties:

- ensures ergonomics of capsule handling,

- the capsules withstand at least 300 cycles between the manufacturer and the seller,

- the capsule is stackable, ie the transport space is minimized when transporting empty capsules,

- the internal shape ensures perfect trouble-free emptying of a wide range of types of goods,

- the capsule may contain RFID or another similar chip, which will facilitate the identification (even in bulk) of the goods in the capsules, or offer, through other connected electronic devices, extended information about the goods in the capsule, including information about its origin.

The capsule consists of several parts. The main one is the body J of the capsule, which is designed to meet the necessary requirements for transport, ergonomics and washing. Its shape is conical and therefore suitable for stacking. Stacking open capsules could cause them to jam. This problem has been eliminated by adding stops to the capsule. These stops prevent the capsules from over-fitting into each other and thus also define the maximum insertion position (Fig. 4). The stops are in the form of four ribs in the inner corners of the capsule. With this modification, the capsules can be easily separated from each other without using excessive force. The capsule insert 2 fits into the body 1 of the capsule (Fig. 1). It is a sloping part with an opening in the middle, forming essentially the second bottom of the capsule, which is to serve to guide the food to the mouth of the capsule, respectively. pouche. It is possible to securely place the RFID chip between these two parts so that it is not damaged, confused or lost. The bottom of the capsule has an opening in which the passage 3 of the inner bag 4 (pouches) protrudes (Figs. 1, 2 and 5). This place is provided with a lower lid 6 (Fig. 1), which snaps directly to the passage 3 and thus protects the seal of the inner bag 4 (pouche) against damage. The bottom of the capsule is provided with a finger gap so that this cap (lower lid 6) can be easily removed before the capsule is placed on the dispensing valve 7. The capsule is open at the top and a large upper lid 5 serves to close it (Figs. 1,2 and 3). ), which holds the rim on the capsule. This hem also acts as a strength element. The upper lid 5 of the capsule is also provided with a rim, which helps to stack the filled capsules and thus keeps them in the right place. There are also several holes in the bottom of the capsule and in its insert 2, which serve to remove excess moisture, especially during washing before repeated use. The bottom of the capsule is also embossed with a special blade 22 (Figs. 30, 31 and 32), which slides under the capsule from the front and thus closes the emptied capsule when it is replaced by a new one in the bulk modular system (BMS). This is also related to the fingerprint in the lower part of the forehead in the body J of the capsule (Fig. 1), behind which the capsule can be lifted and easily removed from the dispensing valve 7 (Figs. 24, 25 and 26). The seating of the capsule on the dispensing valve 7 and securing its position by means of openings in the capsule and protrusions on the guide rails 8 on the valve 7 is described in more detail in the section describing the dispensing valve 7.

The inner bag 4 of the capsule, the so-called pouch (Figs. 1, 13), has the following properties

- it has an integrated discharge passage 3, which is sealed and which then sealed ensures a constant internal environment and the impossibility of contamination of the pouch during transport,

- the pouch is filled after clicking into the capsule from the top and subsequently sealed, but it is possible to fill it even through the passage, which is subsequently sealed - sealing,

- the pouch is disposable, made of a material that is recyclable or compostable,

- a key feature of the system from the point of view of the pouch is that the pouch does not leave the operating cycle of the capsule and is processed for further material or energy use within this cycle; The MIWAtak system fulfills the principles of circular economics.

It is a special disposable bag 4, suitably filling the inner space of the capsule, which at the same time separates it from direct contact with food. This bag has at its mouth an emptying and at the same time filling passage 3 (Fig. 5), which is attached to the bottom of the capsule by a simple click so that it does not move unintentionally. The passage is sealed with a protective foil, which is perforated after placing the capsule on the valve, which makes it possible to subsequently dispense the goods. During transport, the seal on this part is protected by a lid (lower lid 6) at the bottom of the capsule. The passage 3 is the main part which connects the product in the capsule and the dispensing valve 7, its shape is adapted to this so that it connects well to other parts and thus no loss and contamination of the goods occurs. The passage has a hole in the lower part, into which the cutting plate 10 slides during the perforation of the seal. As a result, the cutting plate is separated from direct contact with the goods inside the pouch and thus the mechanism cannot jam due to pinching of the goods between the cutting plate 10 and the passage 3 of the pouch. A number of aspects are taken into account in the design of the pouch and bushing itself. Above all, it is an ideal pouch cut for maximum filling of the capsule space, the use of monomaterial on the pouch foil and penetration (important for recycling), as well as the joining of these parts together. The joint with the penetration is an important place in terms of simplicity and speed of assembly of these parts, but also in terms of tightness and reliability of the joint or. the whole system.

The individual variants of the connection of pouch and passage are also described.

Fig. 6 shows a passage 3 for face welding of the pouch 4. The body of the pouch bushing has a rotating shape. At the bottom, only the tabs that hold the passage in the capsule protrude from it. The main advantage of this solution is the simplification and refinement of the welding of the bushing on the pouch. The weld lines the passage around a larger area, which ensures maximum tightness of the joint. Closing the lower part of the bushing is solved by welding a separate foil. The area where the cutting plate enters is again separated from the area with the product.

Figures 7 and 8 show a variant of the connection of the pouch 4 and the passage 3, where the passage 3 is composed of two parts which are inserted into each other. The pouch 4 is clamped between them. This joint can be disassembled and thus have the foil from the pouch completely separately, for example for further recycling, etc. The closing of the lower part of the bushing is solved by welding a separate foil.

Figures 9 and 10 show another variant of the connection of the pouch 4 and the passage 3, where the passage 3 is composed of two parts which are inserted into each other. The pouch 4 is clamped between them in this case so that it also forms a closure of the lower part. This eliminates the need for any welding.

Fig. 11 shows a variant where the passage 3 is made of only one part, which is inserted inside the pouch 4. It is then pushed through the foil and secured to the bottom of the capsule. It is not necessary to use welding in this version either.

Fig. 12 shows a tubeless system where the tube is cast as part of the pouch 4 and the passage 3. When the lower cap of the capsule is removed, it is released. Subsequently, the capsule is placed on a valve through which the tube passes. After emptying, it still remains part of the pouch in the capsule, so there is no need to clean anything. There is also no need to cut the sealing foil at the penetration, which is replaced by the tube itself.

The dispensing valve 7 is closely connected with the design and construction of the transport capsule and the pouch so that when the capsule is first inserted into the valve, the seal of the pouch emptying passage is automatically perforated without the possibility of any contamination of the goods by the operator (Figs. 18-21). The dispensing valve 7 has these other key features

- its jaws are electronically controlled using integrated scales and elements of artificial intelligence and data analytics so that the required quantity of goods, regardless of its type, is weighed accurately, quickly and efficiently, without unnecessary losses and without any possibility of contamination,

- the goods pass through the jaws through a special tube 11 (Figs. 14 to 23), which ensures a smooth passage of a wide range of goods through the valve,

- the control of the valve 7 is ergonomic and efficient in order to minimize the handling time on the part of the operator or the customer.

The dispensing valve 7 (Fig. 14) follows the shape of the capsule and the pouch and serves for its controllable emptying. The valve body consists of two basic parts, it is equipped with a specially designed internal solution of the dosing mechanism and electronics (Fig. 16 to 21). The process begins by placing the filled capsule on the valve 7. Its exact position is ensured by the guide rails 8 on the valve (Fig. 7), which are complemented by two protrusions (Fig. 14) at the rear, which fit into the back of the capsule, thus preventing unwanted movement. in the vertical direction when cutting the pouche seal. Related to this is a closing rod 9 ("cut-out") in the front part of the valve (Figs. 14 to 17), the insertion of which encapsulates the capsule against vertical movement by means of protrusions by inserting it into the holes in the front part of the capsule. When the rod 9 (Figs. 14, 17) is inserted, one of the other parts 10 of the valve (Figs. 14 to 17, 22 and 23) is moved at the same time, which is provided with a cutting plate which perforates the seal seal. At the same time, there is a silicone tube 11 (Fig. 22, 23) on this part, which forms the path for the goods through the flap mechanism 13 (Fig. 19), resp. the whole valve. A silicone seal 12 is placed around the cutting plate in the upper part of the stone, which hermetically seals the connection between the capsule and the valve. Both the seal and the silicone tube are provided with a flange which is hooked behind the packs in part 10 with a cutting plate. This joint is strong enough, but it can also be dismantled and replaced if necessary. The length of the silicone tube 11 reaches up to the level of the end of the reduction 19 of the hopper. This ensures the so-called secondary tightness, i.e. a better fit of the tube 11 on the inner surfaces of the hopper reduction 19. Sealing these areas with flexible silicone parts has a positive effect on the durability of the goods, prevents the ingress of undesirable organisms and also prevents contamination of the valve 7 from below, which can happen especially with dusty products. When replacing the capsule, the assembly is replaced at the same time: the part 10 with the cutting plate, the silicone tube 11 and the seal 12 and is washed in the dishwasher before further use. The flaps 13 (Fig. 19) in the valve grip the tube 11. There are two and they open by turning by means of electronic servomechanisms 15 (Fig. 20). The opening time and angle can be set differently for each product, as only one default setting cannot be applied to all types of products due to their size and shape. Since clamping the tube with the flaps in only one plane is not sufficient, both flaps are equipped with flap extensions 14 (Figs. 19, 20), which close the tube in two levels above each other. When closing the flaps 14, the upper part is first closed, where a piece of goods may be pressed. When squeezing a larger piece of goods, smaller pieces could fall around, which is prevented by the second flap arm, which closes the tube 11 in the second level below it. Thanks to this, the tube 11 is perfectly sealed not only against falling goods, but also against possible unwanted bacteria, mites, etc. The ends of these flaps (arms) can be made of different materials. Either it is a hard material - plastic, or flexible

-6GB 2020- 470 A3 silicone, which can more easily embrace any remaining goods and seal the tube better. The clamping of the flaps 13 during the inactivity of the valve 7 is secured mechanically by a spring (Fig. 20). In front of the valve 7 there is also a transparent part (Fig. 16) with an indicator light which signals the various states of the valve or the fullness of the capsule, depending on the color in which it is lit. The customer thus safely knows from which valve the goods are to be emptied, and other colors also guide the operator when changing capsules.

A great advantage is also the integration of scales into the valve 7, which allow you to have a real-time overview not only of how much goods the customer has emptied, but also about the overall condition of the goods in the store. The scales 17 are four in total and are inside the valve (Fig. 19), the entire valve (or scales) then sits on the pins 18 protruding from the structure of the BMS device (Fig. 20), whereby the weighing takes place. The lower part of the valve is followed by another separate part, which is the hopper 16 (Fig. 18), which is suspended in the BMS structure. The hopper 16 has in the front part a space for pressing with a finger - a button which is connected with the operation of the hopper, resp. product dosing method. Dosing of the product consists either by pulling the hopper and reducing it towards you by means of a container, or by placing the container under the hopper and pressing a button. At that moment, the hopper only moves in the front part, as the back part is fixed - it makes a rocking motion. By pressing the button or pulling the whole hopper 16, an impulse is transmitted to the flaps 13 in the valve, which open and empty the goods. The space between the BMS sheet metal shelf and the hopper is complemented by springs which, when the hopper moves, put up a slight resistance and, when released, return it to its original position. The hopper 16 is also provided with a return catch which regulates its operation so as not to undesirably relieve the valve on the balance. This method of dosing the product is advantageous especially in terms of accuracy and overview of the dumped goods in the container. In FIG. 21 is a sectional view of the valve, and FIG. 24 to 26 show the seating of the capsule on the valve.

The hopper is supplemented with a reduction 19 (Fig. 18), which is especially advantageous for shopping in bags and sacks. In connection with the possibility of pulling the hopper 16 behind the reducer forwards during shopping, the reducer 19 could be unintentionally pulled out of the hopper 16. Therefore, a reliable bayonet lock was used to connect these parts. In addition, if necessary, it is possible to remove the reducer 19 by simply turning it, for example when replacing the capsule.

The standard reduction of the hopper 16 can be replaced by a so-called umbrella 20 (Fig. 27). This part differs in its shape and size. It is a slightly conical surface, which smoothly changes into the shape of the hopper 16 and is covered with small ribs from the bottom. The umbrella 20 is designed primarily to prevent two problems, namely the elimination of contact of the shopping container with the dispensing device, resp. its contamination (due to the ribs which only touch the point of the outer part of the container neck) and the reduction of dust when dispensing dusty products (better sealing between the container neck and the dispensing device.

The device also includes a manual vibrating lever 21. It is a simple sheet metal tool (Fig. 28), which is, however, crucial in terms of solving several problems that can occur when emptying goods. This lever 21, which is made of stainless steel, is placed on the passage 3 of the pouch (Fig. 29) before inserting a new (filled) capsule on the valve. The lever 21 functions as a key which, in the only correct position, fits exactly into the lower shape of the passage of the pouch around the tabs. After catching the capsule to the valve 7 and perforating the pouch seal, it manually moves the end of the lever 21 towards the sides (Fig. 30). This results in a rotational movement of the passage 3 with the pouch, which improves the perforation of the seal and the release of the goods inside the capsule. The goods can be stuffed during transport, which in itself makes it impossible to empty them from the capsule. The movement of the lever 21 also eliminates one of the biggest problems in the behavior of powdered goods, which form so-called bridges during dumping. Bridges are a phenomenon in which, when emptying any container through the bottom opening, cavities are formed inside the stuffed parts of the goods, which makes it impossible to empty it. The movement of the lever 21 thus solves several problems at once. In order to prevent incorrect use and, as a result, possible damage to the vibrating lever, its design is designed so that this does not occur. Its handle is reinforced by bends, and in addition its movement is limited only to the extent necessary.

-7 CZ 2020- 470 A3

A metal spatula 22 serves as an aid in replacing an empty capsule with a new one (Fig. 31). This is because a small amount of goods may remain in the capsule, which would fall out and make a mess when replaced. For this reason, before removing the capsule, a vane 22 is inserted from the front, which is inserted into the recess in the capsule between the bottom of the capsule and the upper surface of the valve 7 and extends below the passage 3 of the inner bag 4. The blade itself then holds the pouch firmly slid on the side parts of the passage (Fig. 32), to which it simultaneously pulls during insertion and thus completely closes the passage (Fig. 33). Furthermore, the blade at its front is supplemented by a third support point, which slides directly into the opening in the capsule when the blade is fitted. This results in a reliable closure of the capsule during its replacement while maintaining maximum cleanliness. The blade 22 has an opening in its front through which the vibrating lever 21 also passes, which is mounted on the passage from the very beginning.

The dispensing device of the modular BMS system serves primarily to contain the dispensing valves 7 into which the capsules are inserted. The dispensing device is designed and constructed so that

- the work of the operator or customer in dispensing the goods from the capsules was ergonomic,

- the facility was also a storage facility, ie that there was space to place spare full or emptied capsules,

- was modular and allowed for high variability in the use of specific space in specific stores.

The dispensing device is equipped with electronic elements that enable the identification of inserted capsules and the effective navigation of its staff or customers.

The dispensing device is designed in several different variants and is practically a modular system. The variants differ from each other by the number of rows of valves 7 (there are six valves in each row). Depending on the use of 1 or 2 rows (shelves) of valves, they have different heights, but the width and the whole lower part of the BMS are identical. In addition, it is adapted for easy handling when installing the BMS system in various stores. From the point of view of the technical solution, other variants of the number of shelves, valves, height and different dimensions are also possible. Thanks to this variability, it is possible to find the ideal combination for each store that will suit its specific requirements. In addition to the BMS module with valves, the so-called promo module can also be optionally placed, which is based on the BMS module with technology in terms of construction and dimensions. The difference, however, is that it is primarily intended for the storage of smart shopping containers (MIWA CUPs) and visual communication. Communication can be in printed form or projected on a built-in television.

The construction of the BMS system consists of a supporting frame 23 made of steel and sheets (Fig. 34), in which a panel for settling valves and hoppers is prepared, which can be placed at different heights. A visible cladding made of plywood and chipboard is attached to the BMS (Fig. 35) and under the valves there is a shelf, resp. worktop optionally covered with stainless steel sheet for better maintenance. In the right part under the worktop we find a space for storing smart containers. Empty or full capsules or completely different goods can be stored in the lower part. The construction of the BMS is on four rectifying legs (in all corners) for alignment to a horizontal position and in the rear part it is equipped with attachment points by which the BMS can be fixed to the wall. The complete BMS equipped with valves and capsules is shown in Fig. 36. The worktop is equipped with a touch screen, scale and label printer.

During long-term operation of the BMS, unintentional contamination of the BMS worktop can lead to remnants of goods. The increase in cleanliness is helped by the fact that the BMS worktop can be equipped in the right part with a so-called dirt trap 24 (Fig. 37), which consists of a metal grate through which dirt can fall and a metal bowl in which it settles. Everything can be easily disassembled and cleaned (Fig. 38). Therefore, if there is dirt on the worktop, it can easily be loaded into this trap, which must be cleaned regularly.

- 8 CZ 2020- 470 A3

The shelves for the scale are also related to the hygiene of the worktop and the cabinet itself. The balance itself is seated in the worktop and has a gap around it in the worktop for weighing accuracy. Dirt can get inside the BMS body and contaminate the electronics through this gap. For this reason, the construction of the shelf 25 is modified and equipped with a stainless steel tray 26, which fills all the space under the scale and thus at the same time guarantees the capture of all impurities that could pass around the scale. The shelf for the scale is made of bent sheet metal and its construction is designed so that, when viewed from above, there are no surfaces that protrude beyond the silhouette of the scale itself, resp. dirt traps. In addition, the tray is easy to remove and clean. (Fig. 39)

To increase the hygiene in the hopper area, the BMS module can be equipped with a plexiglass shield 27, which protects the hoppers 16 from unwanted hand contact or droplet transfer by bacteria (Fig. 40). The shield is made of clear plexiglass, so a view of the hoppers themselves, respectively. the entire purchase of goods remains clearly visible. The plexiglass 27 is designed so that it can be folded upwards if necessary. This operation is performed when replacing the capsule in the bottom row. The material is smooth and easy to clean.

An important part of the MIWA system is also a smart shopping container, the so-called MIWA CUP. This container is intended for the purchase and storage of bulk and liquid products purchased from MIWA BMS. It is a cup, or. a bottle that is fitted with a well-closed cap. The key feature of the MIWA CUP is its conical shape, resp. possibility of stacking, for easier storage of empty containers or their transfer to the store. Containers are equipped with an RFID (or other) chip, which carries information about a specific container via the information system. The information is used to identify the container before purchase, when the MIWA CUP is attached to the dispensing valve with the required product. At this moment, the information system knows which container it is, resp. what is its real weight. As a result, it automatically tare the checkweigher in the BMS, thus simplifying and speeding up the purchasing process, which takes place without manual tare. The data also stores information about the purchased product (composition, expiration, etc.), but also the life cycle of the container is monitored (everything is also connected to the mobile shopping application). In addition to making it easier to purchase from the MIWA system, the user can be informed, for example, of exceeding the number of use cycles of the container and asked to replace it. MIWA CUP, like the pouch with a passage, is made of monomaterial, so it is suitable for recycling and reuse.

In addition to bulk goods, the system equipment can also be used for liquids. These can be both food and non-food goods (eg drugstore), which significantly expands the range of products sold in the MIWA system. At the same time, the principle from the point of view of the distribution of capsules, which circulate between the product manufacturer and the seller, is maintained, only their content changes. As the use of gravity alone to empty the capsules, as with bulk goods, is not sufficient for many products, it is important to encourage the emptying of the liquid from the capsule. In the case of MIWA, it is possible to use several ways in which the fluid from the pouch in the capsule can be obtained. This involves applying compressed air pressure, pumping the product using a pump, or mechanical pressure on the product. In most cases, it is more advantageous to have the capsule in the standard position (bottom down), but in some methods, emptying can also be performed upside down, or with the capsule lying on its side or at an angle. It is always a matter of ensuring that the capsule is emptied in the maximum amount in connection with maintaining the maximum cleanliness of the system. It is also important to maintain it - to clean the complete lines (hoses) in which the product is located. The existing valve for bulk goods can also be used for liquids in suitable combination with other emptying technology. The principle of clamping the silicone tube, resp. hoses with flaps, which must not be missing for fluids. In addition to gravity itself, each of the methods of emptying the capsule also significantly contributes to the filling speed of the container compared to the gravitational solution, resp. increase shopping speed. This is also influenced by the diameter of the line through which the fluid is forced out of the capsule (where the larger the diameter, the higher the speed). In this case, the silicone tube is tapered to achieve optimum flow.

Fig. 41 shows the pressurization of the product pouch. After dispensing several different variants and consultations, we decided to use a system consisting of blowing compressed air (approx. 0.5 bar) directly into the pouch with a product that increases the pressure in the pouch, thus

-9GB 2020- 470 A3 pushes the product level. As a result, the fluid is subsequently forced out through the passage. Due to the direct contact of compressed air with the product, it is important that it does not cause drying or other degradation of the product. This can be prevented mainly by choosing suitable products for this solution. All valves in each BMS are connected to one central compressor unit (compressor 28). which maintains a constant pressure throughout the system. When emptying a certain capsule, a pressure drop occurs, which is immediately adjusted and maintained at the desired value. Fig. 41 shows the principle of operation, Fig. 45 shows a detailed section.

For MIWA liquid in the MIWA system, the key is to use as much of the existing system as possible for the bulk goods and the parts of which it is composed. An almost complete BMS module with valves, including return capsules, was used. The design of the BMS as such basically does not need any change, it is only supplemented by a drip tray, which is necessary for liquid products.

The fluid valve 29 is also based on the arrangement of the bulk valve and operates on the same principle, except that there is a change of several parts in connection with the compressed air line (Fig. 42). Due to the different requirements and properties of the liquid products, a different type of pouch bushing is created (passage 30 of the inner fluid bag) - (Figs. 44, 45), which in this case has two smaller holes. One serves to blow in compressed air and is stretched towards the pouch in the form of a tube, which prevents the product from being aerated just before the pouch is completely emptied. The tube is terminated with a membrane to prevent the product from flowing back into the compressed air line. The product passes through the second opening when emptied out of the pouch. The principle of piercing the pouch seals (at both holes) is maintained, but the stone itself (part 31 with a cutting plate for fluids - Fig. 42-45) has been changed. In its central part there is an opening through which a silicone tube 32 with a smaller diameter passes than in bulk goods. The tube 32 - the hose for fluids is terminated in the upper part by a transition part for cutting the seal of the pouch bushing (Fig. 44). In the rear part of the stone, the connection of the compressed air line to the pouch bushing continues in the form of a hose towards the rear part of the valve. It also details the reservoir inside the stone body to catch any product residue that could get out through the pressure hole in the pouch bushing. The seating surfaces between the stone and the pouch penetration are completed with a silicone seal. This ensures complete tightness and cleanliness of the system. The stone and silicone tube are removable and easy to clean.

We use the flaps in the valve in the same way as in the system for bulk goods for throttling the silicone tube and their opening is connected with the equalization of the pressure in the system (in the closed state it keeps the pressure inside). The silicone tube is equipped with an anti-drip membrane at the end. The dosing itself is controlled by a button on the hopper, as is the system for bulk goods.

The hopper is shortened and is not equipped with an extension reducer. Instead of a reduction, collets 33 are placed here to hold different sizes of shopping container - bottle. The container in it keeps hooked behind the stock at her throat. The attachment is therefore universal and the shopper does not have to hold the container in his hand while it is being filled (Fig. 45).

The use of existing parts basically brings two significant advantages. The first of them is the appearance of the whole device, which is practically identical to the version with the version with bulk products. Thanks to this, it fits in perfectly with other BMS modules, despite the fact that it is used to dispense completely different types of goods. The equipment in the store thus looks clean and complete. The second benefit is cost savings in the production of new molds for valve parts, respectively. universal use and compatibility of most parts in the system for bulk and liquid goods.

Another option of the fluid delivery system is to pressurize the second pouch in the capsule (Fig. 46). This is a similar principle as with pressurization of a pouch, with the only difference that a second pouch / balloon is used for pressurization. It is necessary that its shape and volume fill the entire space of the capsule and at the same time it gradually increases in the right direction (when it is at the top, it must expand downwards, but not to the sides). This pushes on the pouch with the fluid beneath it and the product is dispensed. The advantage in this case is that the gas driven by the compressor 28 does not arrive

- 10GB 2020-470 A3 in direct contact with the product at all, therefore there is no need to solve its sterilization. In addition, the pressurized pouch / balloon can be used repeatedly, where it can be a stable part of the BMS, or travel under the capsule lid throughout the process.

Pump 34 can be used to drive and dispense fluids (Figs. 47, 48). The most suitable for this application is a gear pump or peristaltic (hose) pump. When the pump is flooded, it runs under vacuum and sucks fluid from the pouch. On the other hand, he pushes her out with increased speed. It is ideal to have the capsule placed downside down for easier suction of the product. In the case of a gear pump, the mechanical parts must be flushed during operation. The goal is to have the shortest possible product management, due to easier maintenance. The ideal solution is to use a pump with a reusable turbine. This mechanical part is of simple construction and is made of only one type of plastic. The turbine is taken as part of the pouch in the capsule. The capsule is mounted on a valve in which the pump drive motor is permanently located, from which only the drive shaft emerges. When the capsule is fitted, the axis and the turbine of the pump are connected, thus activating. The advantage of using a pump is the ability to reverse. When the product dispensing is stopped, the start-up is started briefly, so that any remaining product behind and inside the pump is sucked back. This will prevent air ingress and subsequent drying or dripping of the product. When replacing an empty capsule, the pump turbine is replaced at the same time, which can be used repeatedly or once and then recycled.

Finally, mechanical pushing by means of a scissor mechanism / thread can be used to dispense fluids (Fig. 49). In addition to gas pressure, the pressure on the product pouch can also be developed purely mechanically. This requires a special part, the so-called hoof 35, located above the pouch under the capsule lid. This part pushes the fluid hand over it using a mechanism above it and moves downwards. It gradually copies the shape of the capsule insert so that the pouch is completely emptied. It can be pushed in several ways. This can be achieved by means of an electric motor 36 which drives a scissor mechanism 37. This gradually extends towards the bottom of the capsule. An alternative is to use a helix instead of a scissor mechanism.

An important part of the fluid system is the silicone tube 32 (Fig. 50). This part is removable from the stone in which it is deposited. The end piece is equipped with a membrane, which prevents the penetration of air into the hose and thus limits the drying of the product. At the same time, it acts as a drip barrier, which ensures higher cleanliness of the entire BMS. When any method of emptying is triggered, the fluid pressure pushes the membrane and begins to flow.

The device in the liquid goods variant uses almost all parts of the system as for the bulk goods variant and has essentially the same appearance. To empty the capsule, there is a detachable pump with a drive motor, which is located in the valve and a reusable mechanical part changed at the same time as the capsule, or pressurizing the pouch with the product in various ways.
