Description

Technical area

The present invention relates to a recycling system for the use of marked reusable items, in particular reusable tableware (reusable tableware), and to a separating and receiving device, in particular an intelligent trash can, for automatically sorting out the reusable items. In addition, the invention relates to a separating and receiving device, in particular to an intelligent trash can, for the automatic separation of residual waste and marked recyclable items, in particular reusable tableware.

Technical background

In Germany alone, according to current figures, 2.8 billion disposable coffee cups are thrown away every year after an average of around 4 minutes of use. Many of these coffee cups also come with plastic lids, which are then thrown away along with the cup after a single use. Particularly at large events - for example trade fairs, open-air events or sporting events - disposable tableware such as dinner plates, disposable spoons and knives, disposable chopsticks and the like are often used.

Deposit-free systems for reusing/recycling used dishes have so far only been designed for a very limited number of users. The use of reusable tableware is significantly more complicated at large events. For larger numbers of users, deposit-based systems are usually used, but these are not very flexible in relation to the usage habits of end customers.

As an example, the situation of a typical trade fair visitor is given here: In Hall 1, for example, he buys a coffee in a deposit-restricted mug or a deposit-restricted cup. While he/she drinks the coffee, he/she continues to move through the trade fair event and is already in Hall 2 when the cup or mug is emptied. With typical deposit systems, the trade fair visitor now has to either (i) visit another sales stand of the trade fair provider or an external one Search and find a provider stand in line there, return the cup/cup and receive your deposit or (ii) if he/she cannot find another sales stand, he/she walks back to Hall 1 and returns the cup/cup there, or (iii) He/she waives the deposit and throws the mug/cup into a normal trash can, whereby the dishes are removed from the deposit system and become residual waste.

• Die Zeit des Messebesuchers ist wertvoll und wird mit der Retour des Geschirrs vertan.
• Internationale Messebesucher nutzen vorzugsweise Kreditkarten und können mit dem zurückgegebenen Pfandgeld nichts anfangen.
• Externe Aussteller auf Messen wollen sich nicht mit Rücknahme-Infrastrukturen belasten.
• Messeeigene Verkaufsstellen verlieren Umsatz, wenn sie zusätzlich Zeit für Mehrweg-Rücknahmen aufwenden müssen.

However, this system is very inefficient for the following reasons:

• The time of the trade fair visitor is valuable and is wasted when the dishes are returned.
• International trade fair visitors prefer to use credit cards and cannot do anything with the returned deposit money.
• External exhibitors at trade fairs do not want to burden themselves with take-back infrastructures.
• Trade fair sales outlets lose sales if they have to spend additional time collecting reusable items.

The same or similar arguments apply to other major events and closed areas such as open-air concerts and festivals, amusement parks, zoos, airports or large companies.

However, if reusable tableware were handed out without a deposit at such events and if, for example, special trash cans were set up to take back the reusable tableware, many visitors would ignore them in the hectic pace of the event or out of disinterest and simply dispose of the dishes in trash cans for normal residual waste, which in turn the dishes are removed from the deposit system and become residual waste. This also means a loss for the provider, as reusable tableware is usually more expensive than disposable tableware and the return of a significant portion of the reusable tableware is planned.

Detailed description of the invention in various embodiments

Below, preferred embodiments and features of the present invention will be described in more detail with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. In the drawings, like reference numbers refer to like elements. Conversely, however, the same, corresponding elements in different drawings can be provided with different reference numbers if a passage in the description is intended to refer to a very specific drawing. Redundant descriptions are omitted. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items. Furthermore, the use of "may" when describing embodiments of the present invention refers to "one or more embodiments of the present invention."

It is to be understood that terms such as "first" and "second" are used to describe various elements, but these elements are not limited by these terms. These expressions are only used to distinguish one element from another element. For example, a first element may be referred to as a second element, and similarly a second element may be referred to as a first element without departing from the scope of the present invention.

In the following description of embodiments of the present invention, use of the singular may also include the plural unless the context clearly indicates otherwise.

Relative expressions for describing spatial relationships such as "below", "below", "above", "above", "spaced" and the like may be used below to simplify the Description can be used, whereby the spatial relationship of one element or feature to another element or feature is to be understood as shown in the figures. If one or more coordinate system(s) are included in a figure, relative expressions can also refer to a coordinate system; This is generally explicitly stated again in the relevant passage of the description. It is understood that the spatially relative expressions are intended to include different orientations of the device used in addition to the orientation shown in the figures. For example, if a device shown in the drawings (and, if applicable, each of the coordinate systems shown at the same time) is turned over, elements described as being "below" other elements or features would therefore be positioned "above" the other elements or features. The device may be oriented differently (e.g. rotated 90° or in other orientations); In this case, the prepositions used here to describe spatial relations must be reinterpreted accordingly.

It is also to be understood that when a first element or layer is referred to as being "attached to" a second element or layer, the first layer or element may be attached directly to the second element or layer or but may be attached to the second element or second layer by means of one or more intervening further elements or layers. Furthermore, it is also understood that when an element or layer is described as being "between" two other elements or layers, it may be the only element or layer between the two other elements or layers, or one or more further intermediate elements or layers may be present.

The recycling system according to the invention for the use of reusable items enables the automatic separation of reusable tableware into “residual waste” and reusable everyday items (“reusable”). After cleaning on site (preferably within industrial car washes), the latter goes back into the usage cycle of trade fair companies, festivals, amusement parks, zoos and similar, self-contained events, especially large events.

The unique selling point of the recycling system according to the invention is one Deposit-free use of reusable items, especially reusable tableware, at (large) events, especially in closed areas.

The return process is exemplary as follows: The “intelligent” trash cans according to embodiments of the invention are distributed over the entire area. Visitors buy their drinks and food on the site in reusable containers or disposable containers that are individually branded using cardboard cuffs and throw their unsorted garbage into the “intelligent” garbage containers. The garbage is automatically separated there immediately after it is thrown in. Through this process, visitors do not lose any time due to unnecessary queuing at return stations, they do not have to spend "deposit money" and take it back again, and foreign visitors who may only use credit cards do not have to deal with deposit money that is essentially "worthless" to them. And the sales stations on the premises can also use 100% of their time to sell, instead of wasting part of it by taking back deposited dishes and thus losing sales.

At the monitored entrances and exits of the entire site there are advantageously separate RFID scanners (similar to those found in retail stores), which scan any reusable containers that may not yet have been returned and signal them to on-site service staff. They then ask visitors to throw any reusable containers they may have into the trash cans provided at the exits. This ensures an almost 100% return rate of reusable tableware.

As an additional or alternative expansion stage of the recycling system, reverse vending machines can be set up. These lack a sorting function, but when reusable tableware is thrown in, they scan it, collect it in a container (for non-RFID tableware, the insertion slot remains closed) and credit the user with a predetermined deposit on a credit chip card. The user can then redeem this at participating companies in the fast food catering sector, coffee chains or supermarkets, for example. In this way, the system changes from a deposit-free system to a reusable system that can also be used with a deposit and in open areas. The machine sends its current filling level to a central web server; the operators take care of regular emptying, cleaning and the supply of reusable tableware such as coffee cups or eating bowls.

Figure 1 schematically illustrates an embodiment of one according to the invention Separating device 10 or separating and receiving device 10, which in this exemplary embodiment is designed as an intelligent trash can 10 and is shown using an exploded view. The trash can 10 comprises an outer container 20, a catch container 30a located inside the outer container 20 for residual waste and a further catch container 30b located inside the outer container 20 for reusable items such as reusable tableware (see below Fig. 6 ). In the embodiment shown, the outer container 20 has the shape of a hollow cylinder with a lateral surface 24, the outer container 20 being closed off at the bottom by a bottom surface 22 and having an opening 26 at the top. A hollow cylinder 40 (not to be confused with the lateral surface of the outer container 20) is also mounted in the outer container 20 along the central axis 21.

Starting from the cylinder 40, a collecting device 50 extends above the two collecting containers 30a, 30b and transversely to the central axis 21 of the outer container 20, which in the exemplary embodiment shown essentially consists of a segment 52 in the form of a sector of a circle, the radius of which extends to the inner wall of the Outer container 20 is sufficient. In addition to the segment 52, the collecting device 50 can also have mounting elements for attachment to the hollow cylinder 40 and/or the inner wall of the outer container 20 (not shown), since the collecting device 50 is preferably firmly fixed in the outer container 20. The collecting device 50 is used to collect garbage (residual waste) as well as used reusable items that are thrown into the trash can 10 from above through the opening 72 of a lid 70 (see below). The edges 54a, 54b of the segment 52, which extend radially outward from the central axis 21, are located above the edge 38a or the opening 36a of the collecting container 30a or above the edge 38b or the opening 36b of the collecting container 30b.

Above the collecting device 50 there is a cutting disk 60 which can be rotated in both directions of rotation (indicated in the figure by the double arrow 64) about the central axis 21 of the outer container 20 and which is driven by a central axis stepper motor 86 (see Fig. 4 ) is driven. Except for a recess 62, the cutting disk 60 is circular and extends transversely to the central axis 21 of the outer container 20 to the inner edge of the outer container 20. In the embodiment shown, the recess 62 in the cutting disk 60 has a circular sector-shaped shape, which - in projection in the direction the central axis 21 - is congruent to the segment 52 of the collecting device 50 (see above). The edges 62a, 62b of the cutting disk 60, which run radially in relation to the central axis 21 and which are also the form radially extending edges of the recess 62, have a predetermined width (measured in the direction of the central axis 21) and, in embodiments, can be additionally widened (measured in the direction of the central axis 21) by wiping lips 63a, 63b (cf. Fig. 3 ).

A lid 70 is arranged above the cutting disk 60, which - when the trash can is assembled - completely covers the opening 26 of the outer container 20. In the lid 70 there is an insertion shaft 72 for throwing the garbage into the trash can 10. The lid 70 is placed on the outer container 20 in such a way that the insertion shaft 72 is located just above the segment 52 of the collecting device 50. In the exemplary embodiment shown, the insertion shaft 72 - in projection in the direction of the central axis 21 - is congruent to the shape of the segment 52.

In the position of the cutting disk 60 shown, the recess 62 is located directly and completely above the segment 52 of the collecting device 50 and below the insertion shaft 72 of the lid 70. Garbage thrown into the trash can 10 from above through the insertion shaft 72 would therefore, following gravity, fall through the recess 62 of the cutting disk 60 and are caught by the segment 52 of the collecting device 50.

In order to automatically separate the reusable items belonging to the recycling system from the garbage thrown into the trash can 10, the trash can 10 is equipped with at least one motion sensor and at least one RFID sensor. Figure 1 shows schematically the position of a motion sensor 82 on an inner edge of the insertion shaft 72 in the cover 70. The motion sensor 82 is designed to detect objects falling through the insertion shaft 72 and, when such falling through is detected, to send a signal (hereinafter referred to as a movement signal) to an electronic control system 87 (see Fig. 4 ) to send. The movement signal can be transmitted to the control electronics 87 using a cable or wirelessly.

Furthermore shows Figure 1 schematically shows the position of an RFID scanner 84 (i.e. an RFID reader) on the cutting disk 60. Alternatively, the RFID scanner 84 can also be enclosed in the cutting disk 60 and therefore not visible externally. The RFID scanner 84 is designed to detect RFID signals emanating from an object located on the segment 52, the RFID identifier provided by the RFID signal to be read out and compared with a predetermined set of RFID identifiers, and when an RFID signal is detected with an identifier that corresponds to one of the identifiers specified in the set (ie, when certain items belonging to the recycling system are identified by their respective RFID identifier; see below), to send a signal (hereinafter referred to as detection signal) to the control electronics 87. The recognition signal may, but does not have to, contain the identified identifier; As a rule, it is sufficient for the control electronics 87 to “learn” that any of the specified RFID identifiers has been identified.

After triggering the motion sensor 82 and subsequent identification by the RFID scanner 84 - and after receiving a corresponding motion and detection signal by the control electronics 87 - the control electronics 87 sends a signal to the motor 86 so that it drives the cutting disc (from the in Fig. 1 shown starting position) rotates in the (rotational) direction in which the edge 62a is guided over the segment 52 of the collecting device 50, slips or wipes away, and thus an object located on the segment 52 to the opening 36b of the collecting container 30b for reusable everyday items pushes. The signal to the motor 86 can also simply be the application of a voltage to the motor 86, for example a direct voltage. If the edge 62a of the cutting disk 60 is now guided in particular up to the edge 54b of the segment 52 (or slightly beyond), the object tips over the edge 54b of the segment 52 due to gravity and falls into the catch container intended for reusable items 30b. The control electronics 87 then controls the motor 86 using a suitable signal so that it rotates the cutting disc back to the starting position. Here too, the signal can e.g. B. again be a voltage applied to the motor 86.

However, if the motion sensor 82 is triggered without an item belonging to the recycling system being identified by the RFID scanner 84 (i.e. within a predefined period of time, approximately 0.1 to 3 seconds, from the time the motion sensor was triggered), the control electronics 87 sends a message Signal to the motor 86 so that it drives the cutting disk 60 (from the in Fig. 1 shown starting position) rotates in the (rotational) direction in which the edge 62b is guided over the segment 52 of the collecting device 50, slips or wipes away, and thus pushes an object located on the segment 52 to the opening 36a of the collecting container 30a for residual waste. The signal to the motor 86 can also simply applying a voltage to the motor 86, for example a DC voltage. If the edge 62b of the cutting disk 60 is now guided in particular up to the edge 54a of the segment 52 (or slightly beyond), the object tips over the edge 54a of the segment 52 due to gravity and falls into the collecting container 30a intended for residual waste. The control electronics 87 then controls the motor 86 using a suitable signal so that it rotates the cutting disk 60 back to the starting position. Here too, the signal can e.g. B. again be a voltage applied to the motor 86.

The trash can 10 is closed at the top by a hood or a lid 70 with an insertion shaft 72; the insertion shaft 72 lies exactly above the segment 52 of the collecting device 52 and the recess 62 of the cutting disk 60 when the latter is in the in Fig. 1 shown starting position.

Figure 2 shows schematically embodiments of the essential mechanical components of the trash can 10 of Fig. 1 in section or in plan view. Fig. 2 (a) first shows the rotationally symmetrical outer container 20 in a section through the plane AA as in Fig. 1 shown. In the outer container 20, the collecting containers 30a and 30b are arranged to collect residual waste or recyclable items. On average, the collecting containers each essentially have the shape of a sector of a circle, which extends from the hollow cylinder 40 to approximately the inner wall of the outer container 20.

The wall 39a of the collecting container 30a closes - as in Fig. 1 shown - upwards with the edge 38a down. The wall 39b of the collecting container 30b closes accordingly - as in Fig. 1 shown - upwards with the edge 38b down. The gap between the edges 38a and 38b of the collecting containers 30a, 30b again essentially has the shape of a sector of a circle; this has the angle α in the figure. Directly above (relating to the orientation of the trash can 10 in Fig. 1 ) The segment 52 of the collecting device 50 is arranged in this gap Fig. 2 (b) shows in plan view.

The segment 52 also essentially has the shape of a sector of a circle; This generally has an angle β that is equal to or slightly larger than the angle α. This allows the segment 52 to be arranged in the trash can 10 so that (with reference to the orientation of the trash can 10 in Fig. 1 ) the edges 54a, 54b of the segment 52 are positioned directly above the edges 38a and 38b of the collecting containers 30a and 30b (if α = β), or slightly above the openings 36a, 36b of the Catch containers protrude (if α < β, as in Fig. 2 (a) indicated).

Directly above (relating to the orientation of the trash can 10 in Fig. 1 ) of the segment 52 is again the recess 62 of the cutting disk 60. Fig. 2 (c) illustrates the cutting disk 60 of the trash can 10 from Fig. 1 in top view. The recess 62 also essentially has the shape of a sector of a circle; This generally has an angle γ that is equal to or slightly smaller than the angle β. The reason for this is that the edges 62a, 62b of the cutting disk 60 are in their starting position (see Fig. 1 ) are preferably located at the same time on or at least on the corresponding edge 54a or 54b of the segment 52. This prevents the rubbish from accidentally slipping into the wrong collecting container.

Immediately above (relating to the orientation of the trash can 10 in Fig. 1 ) of the recess 62 in turn is the insertion shaft 72 of the hood or lid 70, which closes the trash can 10. Fig. 2 (d) illustrates the hood or lid 70 of the trash can 10 of Fig. 1 in top view. The insertion shaft 72 also essentially has the shape of a sector of a circle when viewed from above; this preferably has an angle δ that is equal to or slightly smaller than the angle γ. The reason for this is that the insertion shaft 72 is completely above (with reference to the orientation of the trash can 10 in Fig. 1 ) of the recess 62 can be positioned when the cutting disk 60 is in the starting position. This guarantees that objects thrown through the insertion chute fall through the recess 62 and do not land on the cutting disk 60 next to the recess.

Embodiments of the trash can 10 may have a hood or a lid 70, on the top of which one or more solar panels 99a, 99b are attached, as also shown in Fig. 2 (d) schematically illustrated. This means that the entire trash can 10 (board for the control electronics 87, sensors and stepper motor 86) can be operated completely or at least largely in an energy-autonomous manner.

Figure 3 shows a three-dimensional view of a cutting disk 60 and a segment 52 of a collecting device 50 according to an embodiment of the invention. The collecting device 50 and the cutting disk 60 are spaced apart from one another by a distance x. Garbage or objects that lie on the segment 52 and do not reach the height x would therefore not be caught by the edges 62a, 62b during a rotational movement 64 of the cutting disk 60 and would therefore not be caught by them in one of the collecting containers 30a, 30b be “wiped” (cf. Fig. 1 ). On the edges 62a, 62b of the cutting disk 60 of the in Fig. 3 In the exemplary embodiment shown, downward-pointing “wiping lips” 63a or 63b are therefore attached, which extend to the segment 52. When the cutting disk 60 rotates, objects that do not reach the height x would now also be detected - by the wiping lips 63a, 63b.

In further embodiments (not shown), these wiping lips 63a, 63b can additionally or alternatively also extend upwards. This increases the area of the edges 62a, 62b of the recess 62, through which the objects located on the segment 52 are "wiped aside".

Figure 4 shows a longitudinal section through the lower part of an embodiment of the trash can 10 according to the invention. The collecting containers 30a, 30b are arranged within the outer container 20. The collecting container 30a for collecting residual waste is located with its bottom surface 32a on a weight sensor 90a, which is positioned between the bottom surface 32a of the collecting container 30a and the bottom surface 22 of the outer container 20. The weight sensor 90a is designed to measure the weight of the collecting container 30a for holding residual waste. Preferably, the weight sensor 90a is further designed to pass on the measured weight to a web server or to a computer, to smartphones or the like in a local network. This can be done - via cable or wirelessly - directly from the weight sensor 90a or using the control electronics 87. The web server, computer, etc. can then estimate the weight and from this in turn the average level of residual waste in the collection container 30a. Accordingly, there is a weight sensor 90b below the catch container 30b, which can then measure the weight of the catch container 30b in a completely analogous manner and preferably also pass it on, from which the average fill level with reusable objects in the catch container 30b can then be determined.

The fill level of the two collecting containers 30a, 30b can therefore be constantly checked via the weight sensors 99a, 99b underneath. If a predetermined weight limit is exceeded, this can then be transmitted in embodiments of the trash can 10 via an integrated radio module to a web server/computer in the local network, etc. The same applies to other data such as the charge status of the battery 130 and/or the location of the trash container 10 on a predefined area. This data can then be sent via app to the smartphones of the organizer's service staff, who maintain the containers on site (emptying the inner separation containers through the side doors on the trash can, replacing the battery if necessary, returning the dirty reusable tableware to a central collection point for cleaning and reintegration into the overall system).

In the middle of the outer container 20 is located, as in Fig. 4 shown, the hollow cylinder 40; In the exemplary embodiment shown, the control electronics (hereinafter also referred to as “electronics”) are housed in this. The electronics can in particular be designed as a single-board solution, as can be implemented, for example, with the physical computing platform “Arduino”. In particular, there is a stepper motor 86 on a holder 110, which is mounted in the upper region of the cylinder 40. This can be connected to the cutting disk 60 (in Fig. 4 not shown) firmly connected shaft 88 transmits a rotary movement to the cutting disk 60. For the connection between the shaft 80 and the cutting disk 60, suitable slots or openings may need to be made in the wall of the hollow cylinder 40 (not shown). The control electronics 87 is located on a further holder 120, which is mounted here in the central area of the cylinder 40. The control electronics 87 is connected - in each case by cable or wirelessly - to the at least one motion sensor 82 and the at least one RFID scanner 84 , in certain embodiments, possibly also with the weight sensors 90a, 90b.

In addition, the electronics for decoding the RFID identifiers from the RFID signal transmitted by an RFID scanner and/or for evaluating the RFID identifiers by comparing them with a set of stored identifiers can also be integrated into the control electronics 87. For this purpose, the control electronics 87 can of course also be located outside the cylinder 40.

Furthermore, an accumulator 130 can advantageously be integrated in the cylinder 40 as a power source. In embodiments, this can be easily replaced through a suitable opening in the bottom 22 of the outer container 20. An accumulator 130 can be used in addition to or as an alternative to solar panels 99a, 99b, as exemplified in Fig. 2 (d) are shown. Of course, the accumulator 130 can also be positioned at other suitable locations on the trash can 10 in other embodiments.

Figure 5 shows a side view of the outer container 20 in an embodiment of the trash can 10 according to the invention. The outer container 20 here has a door or flap 140, through which the collecting containers 30a, 30b can be removed from the outer container 20 and reinserted. The door or flap 140 may be rotatably attached to the outer container 20 with a hinge 142 and/or may have a device 144 for opening and closing, such as a lock, a pass-through opening or a knob. Alternatively, the outer container 20 can also have two doors or flaps, in particular a first flap for removing/adjusting the collecting container 30a and a second flap for removing/adjusting the collecting container 30b.

As a further feature, embodiments of the trash can 10, e.g. B. in the front area, in particular of the lid 70, have colored LED displays (not shown). These displays can be used to show short information or animations, e.g. B. a "laughing smiley" when a reusable item is thrown in, a "sad smiley" when a conventional disposable item is thrown in - this serves as a gamification element and to motivate visitors.

Finally, trash cans 10 can also be equipped with semi-autonomous, mobile carriages. These act as a “mobile base” in which the trash cans are placed. Fixed service points can then be defined in pre-defined areas, which the trash cans 10 drive to independently using the carriages and where they can be serviced centrally. As soon as a trash can 10 leaves its place, it is preferably replaced directly by an empty copy, which also moves up independently. The autonomous driving of the carriages is realized, for example, via on-board collision avoidance sensors (radar sensors); the overall control can be carried out via a 5G network and a central server. However, another overall control system can also be used, which can alternatively or additionally rely on other networks.

Embodiments of the reusable items for use in the recycling system of the invention are described below. As an example, the description refers to the case of reusable tableware. Embodiments of the reusable tableware according to the invention include a fully recyclable plastic, preferably monoplastic, which is manufactured in the form of beverage cups (with and without lids, removable), eating bowls (with and without lids, removable) and other containers. The unique selling point for tableware is passive RFID transponders, through which the respective piece of tableware can be separated from other components of the overall system (including the garbage containers and acceptance machines) can be identified and sorted into a separate container. The RFID transponders (hereinafter also referred to as RFID chips or RFID tags) can work in the short wave range (HF - High Frequency) or ultra-short wave range (VHF, UHF - Ultra High Frequency). In particular, the transponder is not permanently glued/welded to the tableware item, but is located in a cavity (trough) prepared separately during the casting process, which, after being fitted with an RFID transponder, is welded with a lid made of preferably the same (mono)plastic . Once the cup has reached the end of its life cycle (for example after around 500 washing cycles), the RFID chip is separated from the rest by simply milling open the cavity. The (mono)plastic can be granulated and reused, the same applies to the electronic RFID chip - this results in a 100% recycling rate.

Figure 6 shows a longitudinal section of an embodiment of a reusable object according to the invention (in the example a reusable cup) for use in the recycling system according to the invention. In the bottom 152 of the cup 150 with handle 154 there is a trough 156 which is suitable for holding an RFID transponder 160. The RFID transponder 160 is not welded to the cup 150. The trough 156 can also be closed with a lid 170. The cup 150 and the lid 170 can in particular be made of plastic; Cup 150 and lid 170 are preferably made of the same plastic. The lid 170 can thus be placed over the trough 156, which can then be easily sealed by welding the lid 170 to the bottom 152 of the cup 150. Of course, other methods of closing the trough 156 can also be used, many of which can be found in the prior art. What is described above can also be implemented for a plate, for a bowl, for a bowl, for cutlery or for other tableware instead of a cup.
