EP3361454B1 - Outdoor return system for return of deposit items - Google Patents

Description

The present invention relates to an outdoor collection system for taking back deposits outside a (branch) building of a retailer. The invention is offered as a self-sufficient or building-integrated solution.

Conventional deposit return systems, which are set up to take back returnable bottles and deposit cans, for example, are often found within the branches of retailers. The conventional deposit return systems are so-called indoor systems. This means that the return systems are located within the building itself and are therefore not exposed to external environmental influences (e.g. wind, rain, snow, high summer temperatures, low winter temperatures, and the like). Conventional return systems are often located within the retail space itself. However, there are also variations in which only the return terminals (front of the machine) are arranged within a closed anteroom - separate from the sales area. These anterooms are protected against external environmental influences by separating the anteroom from the outside world with glass walls and sliding doors, for example, in order to ensure an almost constant "climate" in which the electronics of the machine work reliably. These redemption terminals are often built into a wall of the store integrated and connected to a backed-up deposit storage room that is not part of the sales area. However, the fronts of these return terminals are always located in a closed anteroom in order to be able to regulate the environmental conditions (eg temperature, humidity, etc.).

This "closed" anteroom solution is essentially due to the fact that the electronics contained in the return terminals are extremely susceptible to external environmental influences. The corresponding electronic components usually always include a detection system with which the deposit is recorded and identified. These are usually camera systems. These camera systems are often supplemented by lighting systems. The cameras are, for example, sensitive to condensate, which occurs when there are strong and abrupt temperature changes inside the machine.

In addition to these detection systems, there are other electronic components. Printer components used to print vouchers that customers can redeem for money at the checkout are also particularly susceptible to external environmental influences. So-called thermal printers are often used, which print on paper by means of heat. In the event of large temperature and/or humidity fluctuations, these thermal printers either do not work at all or do not work reliably.

The document U.S. 4,316,533A discloses a container return system. The document EP 3 045 831 A1 discloses a compact ventilation system. The document WO 00/31694 A2 describes an outdoor ATM with conditioned air circulating inside. The document U.S. 5,441,160 A discloses a returnable deposit collection and storage system.

Therefore, there is a need for a deposit return system that can be placed outside of a branch, so that space consumption is minimized without having to create an (artificial) vestibule. In this case, at least the return terminal is exposed to weather influences such as rain, snow and wind. The task therefore arises of providing an improved returnable deposit system.

This object is achieved by a return system according to claim 1.

The return system of the invention is designed in such a way that the operator surface, which has the insertion opening, can be used directly in the outside world, so that building construction measures, such as anterooms and the like, can be dispensed with. The return system of the invention is an "outdoor system" that can be used directly in the outside world and can therefore be exposed directly (unprotected by building construction) to weather influences such as snow, wind and the like. In order to prevent the electronic components of the return terminal, which is the direct interface to the user, from being impaired, warm air is circulated through the terminal itself in winter and cold air in summer. The required air is provided via the air reservoir, which is fluidically connected to the terminal. Since the air in the reservoir has an essentially constant temperature, no temperature sensor or similar is required to ensure the functionality of the terminal.

A deposit storage room is an example of an air reservoir, since there is usually a constant temperature, which is ensured in winter by switching on a heating system and in summer by switching on a cooling system. This temperature can be 24°C ± 3°C, for example. In winter or summer, this warm or cold air ensures that the electronic components, in particular the electronic recording device of the terminal, are warmed or cooled. Since the air circulates or flows within the terminal, heat or cold is evenly distributed within the interior of the terminal, particularly as a result of convection. The electronic components of the terminal are therefore insensitive to external weather influences, even when the terminal is outside.

The terminal itself will not be equipped with additional heating/cooling elements, which would represent the usual approach to solve the above problem. Also, no temperature sensor is required in or on the terminal to determine the outside temperature.

Preferably, the air in the air reservoir is regulated to a single, substantially constant temperature.

This temperature may be, for example, the 24°C ± 3°C mentioned above. In this case the air reservoir is preferably equipped with a corresponding temperature sensor which measures the temperature in order to activate heating elements and/or cooling elements connected to the air reservoir should the measured temperature deviate from the preset (constant) temperature.

It is therefore advantageous if the air reservoir has a heating element and/or a cooling element in order to keep the air in the reservoir at a substantially constant temperature.

In a special embodiment, the flow unit includes at least one fan, which is preferably provided inside the terminal.

A fan (e.g. an ordinary PC cooling fan) can be used to generate the necessary air flow inside the terminal. This airflow is sufficient to guarantee the environmental conditions desired for the electronic components. This is especially true in cases of extreme heat or extreme cold in the outside world.

In a further preferred embodiment, at least part of the outer housing, which comprises the section, and preferably one or more further housing elements, form a substantially sealed working volume in the interior space, which is in particular smaller than the total volume of the terminal, with at least the detection device being located within the working volume is arranged.

The (circulating) air flow does not necessarily have to flow through the entire volume of the terminal. A reduction in the working volume, which essentially surrounds the electronic components, facilitates both the design of the flow device (e.g. low-power motor) and isolation (e.g. in the case extreme cold). A microclimate is formed that can be optimally adapted to the detection device.

For this reason, it is also advantageous if the working volume is additionally sealed off from the outer housing by one or more thermal insulation elements.

In particular, the outer housing has, preferably closable, ventilation openings or slits, which can be provided, for example, in an upper area of the terminal in order to allow warm air that has flown in to escape.

The ventilation openings are preferably placed in such a way that the air circulates optimally in the interior or in the working volume. In this way, the air supplied from the air reservoir does not build up inside the interior of the terminal, so that overheating in particular is avoided. This applies to both summer and winter. Air circulation occurs through the openings.

The flow unit is operated unidirectionally, so that the air only flows from the reservoir into the terminal.

In a further special embodiment, the terminal also has one or more of the following components: a printer unit arranged inside and/or outside for outputting a paper coupon; an external electronic display unit for user guidance; an internally arranged lighting unit for illuminating the inserted deposit; a keyboard; a paper coupon output tray; a speaker; one or more external control buttons (including buttons on a display); an internally arranged evaluation unit for processing the detection signal; and an internally arranged conveying device for transporting away the deposit after it has been detected.

All the electronic components mentioned above are vulnerable to external weather influences (humidity, temperature, dust and the like). The air supplied by the air reservoir or the corresponding air flow prevents the External (weather-related) conditions can influence the electronic components. The electronic components work even under extreme outdoor conditions. The reliability of the system increases. System failures are avoided. The service life of the system increases.

The flow unit is preferably provided separately and in addition to the detection device or other components of the terminal.

In a further refinement, the reservoir is implemented by a building construction deposit storage room of the branch building.

This design is advantageous because (particularly rearward) parts of the branch building can be used to provide the air reservoir. In this case, the return system is not a stand-alone solution. Only the terminal or the front of it, for example, is in direct contact with the outside world, and there is no need for a (self-contained) anteroom.

Of course, the air reservoir could also be realized by a building or a room outside the branch.

In a further advantageous embodiment, the section therefore includes a front side of the terminal into which the insertion opening and preferably an electronic display unit for user guidance are integrated, the front side being closable from the outside world in particular by a movably mounted sliding door.

By exposing only the front to the outside world, the area over which heat (or cold) can be exchanged with the outside world is reduced.

If the front can also be closed off from the outside world by a movably mounted sliding door, the terminal is reliably protected from external environmental influences when it is not in use. A sliding door is easy realize. However, the sliding door cannot be compared with a conventional vestibule. With the sliding door solution, there is no need for a heater, which usually has to be provided in the anteroom, for example in order to be able to maintain the desired temperature in winter.

The channel is preferably implemented by a deposit return channel (designed in the manner of a line).

In this case, the returned deposit and the air are exchanged through one and the same duct between the terminal and the reservoir, which reservoir is then particularly implemented by the deposit storage room. This reduces the structural measures required to implement the system. Furthermore, the number of channels to be provided between the terminal and the reservoir is reduced.

It is also advantageous if the terminal also has one or more flow (guiding) elements that guide the air through the interior of the terminal in such a way that at least the detection device is kept at an approximately constant temperature.

These are, in particular, so-called baffle plates, which are arranged and designed in such a way that the air flow is directed through the working volume, in particular where the electronic detection device is located. This prevents air build-up and ensures a constant temperature inside the terminal. It goes without saying that a material other than sheet metal can also be used.

Furthermore, it goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.

1 FIG. 12 shows a schematic top view of an (outdoor) return system 10, which will also be briefly referred to as the "system" 10 in the following. The system 10 is used in retail in particular. The system 10 is set up to take back deposits 14 in exchange for a value coupon, for example. The deposit 14 can be implemented as deposit bottles, cans or the like. The system 10 works autonomously, ie for example also outside the opening times of a retail branch.

The system 10 includes a return terminal 12 , an air reservoir 16 , an air duct 34 , and a flow unit 50 that allows air 52 to flow between the reservoir 16 and the terminal 12 . The flow unit 50 can be, for example, a fan 54, a blower or the like.

The reservoir 16 is integrated into a building 18 of a branch, which in turn includes a sales room. The terminal 12 is not in the sales room, but outdoors 20, ie "outdoor" in an outside world 20 outside of the building 18, respectively. However, the terminal 12 can also be arranged partially within the building 18 . In the 1 the building 18 is shown with a solid line. A dashed line indicates a self-contained anteroom, which in this sense also belongs to building 18. Terminal 12 is located outside the anteroom.

The terminal 12 is arranged with its insertion opening 26 outdoors. The insertion opening 26 serves to introduce deposits 14 from outside the building 18 into the system 10. The insertion opening 26 of the terminal 12 is in the immediate vicinity of an (opto)electronic detection device 28 which is arranged in the interior 24 of the terminal 12. The detection device 28 can be implemented by a camera system 30, for example. The interior 24 of the terminal 12 is surrounded by a preferably sealed outer housing 22 which is or can only be opened through the insertion opening 26 to the outside world 20 . The insertion opening 26 can be designed to be closable, for example, in order to open the opening 26 only when deposit items 14 are being thrown into the interior space 24 . For this purpose, a cover (not shown and labeled in detail) can be provided, which releases the insertion opening 26 as required.

The terminal 12 is separate from the reservoir 16 . The terminal 12 is connected to the reservoir 16 at least via a (preferably thermally insulated) air duct 34 . Depending on the design of the terminal 12 , a deposit return channel 32 is also provided, which also connects the terminal 12 to the reservoir 16 . The return channel 32 for deposits does not necessarily have to be provided, in which case the terminal 12 is then also set up to (internally) store returned deposits 14 after they have been recorded and identified. However, if the channel 32 is provided, the reservoir 16 preferably also serves to store the returned deposit 14, as in FIG 1 shown.

Channels 32 and 34 are typically provided on a rear panel 36 of terminal 12 . The insertion opening 26 is typically on a front face 38 of the terminal intended. It goes without saying that the insertion opening could be provided on either side. The front side 38 or at least the insertion opening 26 defines an unprotected section 40 of the terminal 12. The unprotected section 40 is exposed (in terms of building construction) to weather influences 42 (eg rain, snow, wind, heat, cold, etc.) directly and unprotected. The section 40 is also not separated from the outside world 20 by an anteroom.

The flow unit 50 is arranged within the channel 34 by way of example. However, the flow unit 50 is preferably arranged on or in the terminal 12, as will be explained in more detail below. A flow sensor can also be provided to ensure a constant air flow.

The flow unit 50 transports air 52 from the reservoir 16 into the terminal 12. The flow unit 50 allows the air 52 to flow unidirectionally from the reservoir 16 into the terminal 12.

It is also possible for channels 32 and 34 to be implemented by a single channel.

The reservoir 16 is connected to a heating element 56 (eg a gas or electric heater) and/or to a cooling element (eg air conditioning) 58 . The heating element 56 and the cooling element 58 are connected to a temperature control element 60 which in turn is connected to a temperature sensor 64 which can measure a temperature in the reservoir 16 . A further temperature sensor 62 can also be provided in order to determine the temperature of the air 52 outside the reservoir 16 and/or the terminal 12 . The temperature control element 60 can be used to set a predetermined temperature (eg +24° C.±3° C.) that is preferably constant throughout all seasons. In the winter, the air 52 from the reservoir 16 then heats the terminal 12. In the summer, the air 52 from the reservoir 16 then cools the terminal 12. No heating or cooling elements 56, 58 need to be provided within the terminal 12. It goes without saying that additional heating and cooling elements 56, 58 can also be provided in or on the terminal 12. The essential heating/cooling capacity for an airflow 66 (please refer 2 ) is however supplied by the reservoir 16. It is preferred if the terminal 12 does not have its own heating elements 56 and cooling elements 58, with the weather-independent operation of the terminal 12 still being ensured.

If the reservoir 16 is realized by the deposit storage room itself, where in particular collection bins 68 are provided for storing the various returned deposits, resources can be used which are already available in a branch of a retailer. In this case, no additional heating elements 56 and/or cooling elements 58 need to be provided for the terminal 12. Finally, these elements 56 and 58 are already present. Also, no space is lost. No additional building has to be erected for the reservoir 16 either. Alternatively, the air from the store's salesroom itself could be used, since the salesroom is always air-conditioned.

2 shows a schematic side view of a system 10 in which the terminal 12 is positioned completely, ie in its entirety, in the outside world 20 . The terminal 12 is connected to the reservoir 16 here, for example, via two channels 32 and 34, which reservoir 16 is in turn designed as a deposit storage room. In the 2 an air flow 66 is shown in the form of an arrow, which begins in the reservoir 16, extends through the channel 34 into the terminal 12 and the terminal 12 escapes at a top side 70 and/or the rear side 36 via ventilation openings 72, not shown in detail. The (driven) flow unit 50 is provided at the rear 36 of the terminal 12 here.

The housing 22 of the terminal 12 can also be provided with a (service) door 74, which is described below with reference to FIG 3 will be described in more detail. The door 74 also has an unspecified (insertion) opening, which is preferably aligned with the insertion opening 26 of the housing 22 of the terminal 12 . The door 74 can include a display unit 76 (eg an LCD display) for user guidance. The display unit 76 is preferably attached at an ergonomic height so that it is visible from the outside.

One or more flow guide elements 78 can also be provided in the area of the door 74, which optimally guide the air flow 66 through the interior space 24. In the example of 2 a flow guide element 78 is provided in a middle height area of the door in the form of a metal sheet, which is eg bent in such a way that the air flow 66 is deflected in the direction of the detection device 28 and an (optionally provided) lighting unit 80 . The lighting unit 80 is used to illuminate the inserted pledged item 14 in order to improve detection.

Furthermore, in the door 74 or the front 38 (if the door 74 is not provided), the following components (not shown and labeled in detail) can be provided, namely a keyboard, a paper coupon dispenser, a speaker, or several control buttons arranged on the outside, an evaluation unit arranged on the inside for processing the detection signal, a printer unit arranged on the inside and/or on the outside for outputting a paper coupon, and a conveyor device 82 arranged on the inside for transporting away deposited goods 14 after they have been recorded. Further conveying devices 82 can be provided in the return channel 32 and within the reservoir 16 for the transport of the deposits 14 . The transport of the pledged goods 14 is in the 2 indicated by arrows.

Furthermore, a, preferably smaller, working volume 84 is defined in the interior 24 of the terminal 12 2 is surrounded by a dashed line. The working volume 84 is usually smaller than an overall volume of the terminal 12. The working volume 84 is formed by at least part of the outer housing 22 and preferably one or more further housing elements 86.

In the 2 a further housing element 86 is shown as an example in the form of a horizontal intermediate floor, which bisects the interior space 24 of the terminal 12 in the vertical direction. This reduces the volume through which the air flow 66 must flow. The air 52 is supplied from below, for example, and escapes at the top. It goes without saying that this can also be done in reverse, but also from the side.

In any case, the working volume 84 contains the electronic detection device 28, which is absolutely necessary for the detection and identification of the deposited goods 14 that have been introduced. If the terminal 12 has other (vulnerable) electronic components, it is advisable to design the working volume 84 in such a way that all of these electronic components are within the working volume 84 . Alternatively, the further electronic components are to be arranged in such a way that they are positioned within the working volume 84 defined in advance.

In the example of 2 In addition to the detection device 28, the lighting unit 80 and the display unit 76 (in the door 74) are provided. The housing 22 and the other guide elements 86 and the door 74 are designed in such a way that the air flow 66 can reach the electronic components, either to cool them or to heat them up and thus ensure their functionality, even under the most adverse conditions.

It goes without saying that the flow guide elements 78 can also serve as housing elements 86 and vice versa.

In 3 is a terminal 12 isolated perspective from the front ( Figure 3A ) and from behind ( Figure 3B ) shown. The Terminal 12 of 3 again has a door 74 which can be opened and closed (see arrow 88). In the 3 the terminal 12 is shown in an open door position. Channels 32 and 34 are not shown. Channels 32 and 34 connect to rear panel 36. Accordingly, by way of example, two fans 54-1 and 54-2 are arranged on the rear side 36 of the housing 22 (offset inwards). The ventilation openings are arranged on the rear side 36, but can also be provided on other sides of the housing. The geometric shape of the openings can be chosen arbitrarily. The same applies to their number and arrangement. Good circulating airflow 66 is desired.

How out Figure 3B As can be seen, the working volume 84 only extends in an upper region of the terminal 12. In this sense, the terminal 12 is divided into two, for example, with the working volume 84 being arranged above a base 90 which is formed by parts of the housing 22. The base 90 can be open on one or more sides be trained. In the Figure 3B the base 90 is open at the back, for example because the terminal 12 is integrated into the outer wall of the building 18, as exemplified with reference to FIG 4 will be explained in more detail. However, if the terminal 12 is set up alone outside of a building 18, it is advisable to design the outer housing 22 to be completely closed.

The embodiment of the terminal 12 of 3 also serves to illustrate the possibility that the terminal 12 can be provided with thermal insulation elements 92 . In the Figure 3B only the base 90 is provided with three thermal insulation elements 92. It goes without saying that the upper part of the housing 22, in particular the working volume 84, can also be provided with additional thermal insulation elements 92. This is particularly recommended when using Terminal 12 in cold environments.

4 shows the terminal 12 of the 3 in an installed condition. In the 4 For example, two terminals 12 are shown with the left terminal 12 door 74 open and the right terminal 12 door 74 closed.

figure 5 shows the integration of the in 4 shown unit in a branch. In the figure 5 the branch is shown in perspective. The two terminals 12 are in direct contact with the outside world 20. The terminals 12 are arranged in a kind of anteroom. However, the anteroom is not closed off from the outside world 20 . The terminals 12 are therefore directly exposed to environmental influences.

In order to reduce the influence, further elements can be provided, such as movably mounted sliding doors 94. The 6 shows a front view of a sliding door 94 in the closed state ( Figure 6A ) and in the partially open state ( Figure 6b ). In the 6 the sliding door 94 can move to the left to release the terminals 12 for the insertion of deposits 14. The sliding door 94 represents an implementation of the closable insertion opening 26 mentioned above. The sliding door 94 preferably faces the fronts 38 of the terminals 12 directly. The sliding door 94 extends parallel to the building 18 and can also be provided with a Seal 96 that is attached to building 18 interact. In the design of the terminals 12 according to 6 the terminals 12 are directly exposed to the environment 20 only during the insertion of the deposit 14 . Nevertheless, they are exposed to the environment 20 and are not protected from the outside world 20 as is the case with closed vestibules.

It should be understood that in the above description, although various implementations of the system 10 have generally been shown, repetitive components have not been repeatedly described. The above description is intended solely to provide a general understanding of how the present invention is constructed and functions. Individual or multiple components of different embodiments can be exchanged or interchanged without departing from the scope of the invention. <u>REFERENCE LIST</u> 10 (OUTDOOR) RETURN SYSTEM 72 VENTILATION OPENING 12 (RETURN) TERMINAL 74 DOOR OF 12 16 AIR RESERVOIR 76 DISPLAY UNIT 14 DEPOSIT 78 FLOW GUIDE ELEMENTS 18 BUILDING 80 LIGHTING UNIT 22 CASE OF 12 82 CONVEYOR 24 INTERIOR OF 12 84 WORKING VOLUME 20 FREE/OUTDOOR/OUTSIDE WORLD 86 OTHER HOUSING ELEMENTS 26 ENTRY HOLE 88 OPEN/CLOSE 28 DETECTION DEVICE 90 BASE 30 CAMERA SYSTEM 92 THERMAL INSULATION ELEMENT 32 DEPOSIT RETURN CHANNEL 94 SLIDING DOOR 34 (AIR) DUCT 96 SEAL 36 BACK OF 12 38 FRONT OF 12 40 UNPROTECTED SECTION OF 12 42 WEATHER INFLUENCE (RAIN, SNOW, WIND ETC.) 50 FLOW UNIT 52 AIR 54 FAN 56 HEATING ELEMENT 58 COOLING ELEMENT 60 TEMPERATURE CONTROL 62 TEMPERATURE SENSOR 64 TEMPERATURE SENSOR 66 AIRFLOW 68 COLLECTION CONTAINER
