STORAGE DEVICE FOR STORING PRODUCTS IN A COMBINATION Vending Machine, Vending Machine AND METHOD

Description

AREA OF INVENTION

[0001] The present invention relates to a storage device for storing products in a combination vending machine. Furthermore, the invention relates to a vending machine and a method for taking back or dispensing products using a combination vending machine. TECHNICAL BACKGROUND

[0002] Vending machines, or simply vending machines, often also called self-service machines, have long been used to sell food, beverages, cigarettes, or other items and can come in a wide variety of designs, such as confectionery machines, beverage machines, cigarette machines, general merchandise machines, and the like. In the case of combination machines, returnable items can also be used.

[0003] The deposit items can be products such as PET bottles, CO2 bottles, glass bottles, beverage cans, reusable items or similar, which are to be collected in a take-back system.

[0004] Combination vending machines are designed to both dispense products and store returned products. A storage device is particularly necessary when more products are dispensed than are received, i.e., when more products are returned to the vending machine than are dispensed.

[0005] Furthermore, a storage device is necessary when products are only handed out or taken back without any products being dispensed in between, a process known as collective collection.

[0006] Unlike deposit return machines, combination vending machines typically lack a conveyor belt or a hopper, meaning products cannot be stored. However, it is advantageous if the dispensed products are temporarily stored in a storage device before being sorted into specific compartments. For example, a CO2 combination vending machine allows products to be sorted into their designated slots only after products have been removed from the hopper. This removal from the hoppers should ideally only occur after the products have been dispensed.

[0007] US Patent 2021 / 256792 A1 discloses a storage device for storing products, comprising a receiving unit designed as a loading tray and a storage unit designed as a tray with a ramp. A product can thus be placed into the loading tray and from there dispensed into the storage unit.

[0008] For further information on the state of the art, reference can be made to US 2022 / 058604 A1, US 2022 / 204280 A1 and GB 2 602 803 A. SUMMARY OF THE INVENTION

[0009] Against this background, the present invention aims to provide an improved input or output of products in a combination vending machine.

[0010] According to the invention, this problem is solved by a storage device with the features of claim 1 and / or by an automatic device with the features of claim 10 and / or by a method with the features of claim 11.

[0011] Accordingly, the following is planned: A storage device for storing products in a vending machine, comprising a receiving unit for receiving at least one product, wherein the product can be inserted into or removed from the receiving unit through an input opening, and a storage unit for storing at least one product within the vending machine, wherein the storage unit has a first pivoting device such that the storage unit can be pivoted upon contact with the receiving unit, wherein the storage unit is designed as a U-shaped holding element which, when a product is received, aligns itself through the gravitational deflection about the first pivoting device, wherein the receiving unit and the storage unit have corresponding edge regions, each with at least one contact surface, such that the receiving element can be supported on the storage unit or vice versa.such that, by contact of the receiving unit with the storage unit in a first position, the product can be transported from the receiving unit to the storage unit by gravity, and, by contact of the receiving unit with the storage unit in a second position, the product can be transported from the storage unit to the receiving unit by gravity. A vending machine for the return or dispensing of products, in particular a combination vending machine, with a storage device according to the invention. A method for the return or dispensing of products with a combination vending machine, in particular for the return of deposit items such as CO2 bottles, comprising the steps: providing a storage option for at least one product onto a receiving unit by means of an input opening; contacting the receiving unit with a storage unit.wherein the receiving unit and the storage unit have corresponding edge regions, each with at least one contact surface, so that the receiving element can be supported on the storage unit or vice versa, such that, through contact of the receiving unit with the storage unit in a first position, the product is transported from the receiving unit to the storage unit for retrieval by gravity, and, through contact of the receiving unit with the storage unit in a second position, it is transported from the storage unit to the receiving unit for dispensing by gravity.

[0012] The insight underlying the present invention is that a storage device makes it possible to accept products collectively in a combination vending machine without having to dispense a product in between.

[0013] The idea underlying the present invention is to design a receiving unit for contact with a storage unit, so that the products can be transported from the receiving unit to the storage unit, and vice versa.

[0014] Furthermore, such a storage device enables the coordinated transfer of products, especially deposit containers or goods, in such a way that the deposit containers can then be stored in a coordinated manner, both stacked on top of each other and side by side. This prevents damage to the deposit containers and simultaneously allows for space-saving storage.

[0015] The input opening can be a passage located in the front area of ​​the combination machine. Preferably, the product, particularly in a horizontal position, can be inserted through the input opening.

[0016] The receiving unit is, in particular, a unit onto which the products are placed when they are inserted into the vending machine through the input opening. Furthermore, the products can be removed from the receiving unit through the input opening.

[0017] The storage unit is specifically a unit located inside the vending machine and is inaccessible to customers or from the outside. Therefore, the storage unit serves primarily for the temporary storage of products before they are sorted into the appropriate chutes or stored in collection containers.

[0018] The receiving unit and the storage unit are preferably aligned with each other in the combination machine in such a way that a transfer of at least one product from the receiving unit to the storage unit or from the storage unit to the receiving unit is possible.

[0019] In particular, when the recording unit comes into contact with the storage unit, a transfer area can be formed, which is made possible by contact with the corresponding edge areas.

[0020] The storage unit and the receiving unit each have at least one contact surface at their corresponding edge regions, allowing the receiving element to be supported against the storage unit or vice versa. These contact surfaces can be created, for example, by chamfered edge regions or similar features. Similarly, aligned edges can serve to form the corresponding edge regions as contact surfaces. In particular, the edge regions are designed as linear or planar contact surfaces. Furthermore, point-like contact surfaces can be implemented. The contact surface can cover the entire respective edge region. Additionally, multiple contact surfaces can be provided, spaced apart from each other along the edge region. Preferably, there are two contact surfaces per receiving unit.Storage unit provided to enable aligned contact in the first position as well as the second position.

[0021] The storage unit has a first pivoting device, allowing it to pivot upon contact with the receiving unit. Accordingly, the storage unit can also be pivoted to enable contact between the corresponding edge regions in at least two different positions. In particular, the two pivoting devices are aligned such that their respective pivot axes are parallel to each other. In a further embodiment, the two pivot axes can also be aligned transversely or at an angle to each other.

[0022] The storage unit is designed as a U-shaped retaining element, which, when a product is inserted, self-aligns due to the deflection caused by gravity around the first pivoting device. The U-shaped retaining element allows the product to be held in the storage unit solely by gravity when the storage unit is not in contact with the receiving unit. This creates a kind of support angle in which the product can be securely held. An edge region of the U-shaped retaining element can have a flat surface that can form part of the first or second inclined plane. Accordingly, a section of the U-shaped retaining element located opposite the second pivoting device can form an edge region that is designed to contact the receiving unit and thus form an inclined plane with it.

[0023] The product, in particular a CO2 cylinder, can roll from the receiving unit to the storage unit when it has been placed on the receiving unit and is subsequently to be temporarily stored in the vending machine. Furthermore, the product, in particular a CO2 cylinder, can roll from the storage unit to the receiving unit when the product is to be dispensed.

[0024] Advantageously, the receiving unit and the storage unit can therefore be arranged in at least two positions relative to each other. These two positions are determined in particular by the fact that the receiving unit and storage unit are oriented differently relative to each other, thus creating a respective transfer area that allows different movements of the product, especially different rolling or sliding movements, in different directions solely due to gravity.

[0025] The respective transfer area is located specifically in the area where the two edge areas can make contact. Corresponding edge areas are designed to allow transfer from the receiving unit to the storage unit and vice versa. Therefore, when the corresponding edge areas come into contact, a rolling surface is formed that enables the product to roll over it.

[0026] The number of storage units can vary, and in particular, a multiple storage units may be provided side by side or one above the other to temporarily store a multiple of products.

[0027] Advantageous designs and further developments result from the further sub-claims as well as from the description with reference to the figures in the drawing.

[0028] According to an advantageous embodiment, the receiving unit can have a second pivoting mechanism, allowing the receiving unit to pivot towards the storage unit. This enables, for example, an upward or downward pivoting direction, allowing a product to be transferred from the receiving unit to the storage unit. If the receiving unit is located below the storage unit, the pivoting direction or movement is upward to transfer the product from the receiving unit to the storage unit. Furthermore, a downward pivoting movement is possible if the receiving unit is located above the storage unit and a product is to be transferred from the receiving unit to the storage unit. The storage unit and the receiving unit can also be arranged side by side.

[0029] According to one embodiment, the second pivoting device can be arranged in the area of ​​a first edge region on the receiving unit. This makes it possible, in particular, to guide a product over the receiving unit in the area on which the second pivoting device is arranged. Specifically, a kind of rollover area can be formed above the second pivoting device. In this way, the edge region of the receiving unit can be located in the area of ​​the second pivoting device.

[0030] According to one embodiment, the first pivoting device can be arranged opposite a second edge region on the storage unit. This makes it possible, in particular, to guide a product over the storage unit in the area opposite the first pivoting device. Specifically, a kind of rollover area can be formed on the storage unit opposite the first pivoting device. This allows the edge region of the storage unit to contact the edge region of the second pivoting device without the first pivoting device hindering the transfer of the product. This is particularly advantageous when the receiving unit is arranged below or next to the storage unit.

[0031] According to an advantageous embodiment, the first pivoting device of the storage unit can be self-resetting. Self-resetting means, in particular, that the storage unit rotates back to its initial position after contact with the receiving unit, without the need for a drive element. For this purpose, at least one return element, such as a return spring or tension spring, can be provided to move the storage unit back to its initial position in a self-resetting manner. The return element is located, in particular, in the area of ​​the first pivoting device, thus enabling a space-saving self-resetting rotation of the storage unit.

[0032] According to a preferred embodiment, the corresponding edge regions can form a first inclined plane in the first position and a second inclined plane in the second position when the receiving unit and the storage unit are in contact. An inclined plane particularly enables a cylindrical or otherwise shaped product to roll or slide from the receiving unit to the storage unit, or vice versa. An inclined plane is made possible, in particular, by contact between the corresponding edge regions, whereby sections of the receiving unit and the storage unit adjacent to the edge regions can form the inclined plane. In this process, the storage unit and the receiving unit are each pivoted, in particular, to be aligned at a desired angle to each other in order to form a continuous inclined plane.

[0033] According to further training, the slope of the first inclined plane can be oriented opposite to the slope of the second inclined plane. This allows rolling or sliding in two essentially opposite directions.

[0034] In one possible embodiment, particularly for transferring a product from the receiving unit to the storage unit, the receiving unit can be pivoted, for example, by a rotation angle of 90° to 120°, particularly 110°, and especially pivoted upwards. By pivoting the receiving unit, its edge region can contact the storage unit, i.e., its edge region. This can, for example, trigger a rotation of the storage unit. The storage unit can thus be deflected such that the first position is formed, wherein the first inclined plane has a gradient of 1° to 10°, particularly 3° to 5°, preferably 4° or 5°. Under such a gradient, the product can, for example, roll or slide onto the storage unit by gravity alone. Other gradient angles are equally suitable for enabling the product to roll or slide.

[0035] In one possible embodiment, particularly for transferring a product from the storage unit to the receiving unit, the receiving unit can be pivoted, for example, by a rotation angle of less than 90°, in particular by 70° to 85°, preferably 80°, and in particular pivoted upwards. By pivoting the receiving unit, the edge region of the receiving unit can contact the storage unit, i.e., the edge region of the storage unit. This can trigger a rotation of the storage unit, the rotation being different from the rotation described above in the first position. For example, the storage unit can be deflected such that the second position is formed, wherein the second inclined plane has a gradient of 1° to 10°, in particular 3° to 5°, preferably 4° or 5°. Under such a gradient, the product can, for example, roll onto the receiving unit by gravity alone.sliding. Other gradient angles are equally suitable for allowing the product to roll or slide.

[0036] The different inclined planes are achieved in particular by arranging the recording unit and the storage unit differently relative to each other, and especially by deflecting them differently rotationally.

[0037] In particular, the distance between the recording unit and the storage unit is designed differently in the first and second positions, so that, in combination with the different deflections of the storage unit and the recording unit, the first and second inclined planes can be achieved. A transport unit can be provided for this purpose.

[0038] It is also conceivable that a product that is not cylindrical could slide down the inclined plane due to the slope. In one embodiment, the slope of the first and / or second inclined plane can therefore be between 5° and 10°, and in particular more than 10°, to allow sliding on the surface of the inclined plane depending on the product geometry.

[0039] Preferably, the recording unit can be linearly movable such that it can be moved away from or towards the storage unit. For example, the recording unit can be displaceable parallel to the storage unit. In particular, a sloping plane, as previously explained, can be achieved by a linear displacement of the recording unit.

[0040] According to an advantageous embodiment, a transport unit can be provided for the guided movement of the receiving unit and / or the storage unit, wherein the receiving unit and the storage unit can be moved automatically towards and / or away from each other by the transport unit. For example, several storage units can be provided along a transport unit to bring the different storage units into contact with the receiving unit. The transport unit can be designed as a guide device. In particular, a plurality of storage units are provided, each capable of receiving a product. This allows products to be temporarily stored. Alternatively, only one receiving unit is provided, which can, for example, also be moved by a transport unit.In another embodiment, several receiving units can be provided in order to simultaneously remove or dispense several products.

[0041] According to an advantageous embodiment, the transport unit can include a carriage. The carriage is specifically designed to move the transport unit along a defined direction. This direction is particularly transverse to the direction in which the receiving unit can be moved towards or away from the input opening. Thus, the carriage can be configured to move the receiving unit towards or away from the input opening and to move the transport unit transversely to the input opening. This allows at least one product to be dispensed at a desired position within the vending machine, which can be selected independently of the input opening.

[0042] The storage unit can also have a carriage. However, in particular, multiple storage units are mounted on a type of conveyor belt or chain element, for example designed as a guide device, to enable the temporary storage of multiple products and to move the storage units linearly.

[0043] According to an advantageous embodiment, the receiving unit can be designed as a U-shaped retaining element. The U-shaped retaining element can be designed similarly to that of the storage unit. In particular, a section of the U-shaped retaining element, on which the second pivoting device is also provided, can be designed as a flat surface. This allows a continuous inclined plane to be formed by contact between the receiving unit and the storage unit. In particular, a kind of rolling edge can be formed, creating an edge region of the receiving unit.

[0044] According to a further development, the second swiveling device can be driven by an electric motor, wherein a drive shaft of the electric motor is connected to the swiveling device, so that by rotation of the drive shaft a deflection of the swiveling device about the drive shaft can occur.

[0045] According to an advantageous embodiment of the method, the first and second positions can be achieved depending on the distance between the receiving unit and the storage unit. In particular, the distance between the receiving unit and the storage unit can be adjusted by a linear movement of the receiving unit relative to the storage unit, thus enabling the dispensing of a product from the storage unit to the receiving unit, or vice versa. This movement can be achieved, for example, by moving the storage unit, especially by a transport unit. Furthermore, the movement can be achieved, for example, by moving the receiving unit, especially by a transport unit.

[0046] The distance can be changed, in particular, by moving the receiving unit parallel to the storage unit. The only important thing is that the receiving unit and the storage unit can touch at their corresponding edges to allow the product to be transferred.

[0047] In particular, the storage unit and / or the receiving unit is arranged to be horizontally movable. In such an embodiment, the receiving unit is, for example, positioned above or below the storage unit. The distance is determined by a horizontal distance at which the receiving unit is positioned relative to the storage unit. When the storage unit contacts the receiving unit, a different horizontal distance allows for different deflections of the storage unit in response to the deflection of the receiving unit. In particular, this allows the first and second inclined planes to be formed.

[0048] The above embodiments and further developments can be combined with one another as appropriate. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention. CONTENT OF THE DRAWING

[0050] The accompanying figures are intended to provide a further understanding of the embodiments of the invention. They illustrate embodiments and, in conjunction with the description, serve to explain the principles and concepts of the invention. Other embodiments and many of the advantages mentioned will become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale.

[0051] In the figures of the drawing, identical, functionally equivalent and similarly acting elements, features and components - unless otherwise stated - are each provided with the same reference symbols. DESCRIPTION OF EXAMPLES OF EXECUTION

[0052] The Figures 1(a) and 1(b)Figure 3 shows an embodiment of a receiving unit 3 in an exemplary embodiment, showing how it can be combined with a storage unit 22 to form a storage device 21. The receiving unit 3 is designed to receive a product 2, which can be, in particular, a returnable product such as a CO2 cylinder. The receiving unit 3 has a second pivoting device 14, which is mounted, for example, on a frame 15. The mounting is, for example, on a drive shaft 16 of an electric motor, the drive shaft 16 simultaneously forming a pivot axis 17 for the pivoting device 14. The frame 15 is open on one side, so that the pivoting device 14 projects beyond the frame 15 on the open side. This ensures easier removal or dispensing of the product 2 from or into a vending machine, such as in a combination vending machine. Fig. 15 shown.

[0053] Rollers 10 are arranged on the frame 15, so that the receiving unit 3 is positioned relative to a transport unit 5, as exemplified in Figures 11 to 14 The frame can be moved. In particular, four rollers 10 can be provided, with each roller 10 being arranged in a corner region of the frame 15. In particular, the rollers 10 preferably lie on the same plane to form a plane of movement.

[0054] The receiving unit 3 can be moved automatically by the transport unit 5 at least towards an input opening 4 of the combination machine and / or away from the input opening 4, as shown in Fig. 15The transport unit 5, for example, has guide elements 8 in which the rollers 10 can be mounted. The guide elements 8 can, for example, be designed as stop elements 9, preventing the rollers 10 from moving vertically upwards. The transport unit 5 also prevents the rollers 10 from moving vertically downwards, thus forming guide rails for the rollers 10. The guide elements 8 can be formed as L-shaped, bent sheet metal elements made from material taken from an opening 6. Through the opening 6, the product 2, which is mounted on the swivel device 14 of the receiving unit 3, can be discharged downwards, for example, into a collection container or a chute. This also ensures that the products 2 are stored in an aligned position.

[0055] An electric motor 18 can be provided outside the frame 15 to drive the drive shaft 16. The product 2 can extend beyond the frame 15 at the open side of the frame 15, allowing it to be ergonomically guided to an input opening 4, see Figure 1. Fig. 15 The receiving unit 3 has a guide pin 13 on its underside, which is aligned with respect to the Figures 11-14 will be described in more detail.

[0056] The drive shaft 16 is positively connected to the swiveling device 14, so that a movement of the drive shaft 16 is directly converted into a movement of the swiveling device 14. The drive can also be provided, for example, by a gear, belt, or worm gear. A drive with a rack and pinion, a cable, hydraulic, or pneumatic mechanisms is also conceivable.

[0057] According to the invention, the products are dispensed, in particular upwards, into the storage unit 22. The receiving unit 3 can be configured differently from the illustration, in particular without the transport unit 5 and without downward output.

[0058] Fig. 2 Figure 1 shows a possible arrangement of the storage unit 22 above the receiving unit 3. In the illustrated embodiment, the receiving unit 3 is arranged offset to the left of the storage unit 22. A guide device 23 and / or a transport unit, for example shown in Figure 2, can be used to guide the storage unit 22. Figures 11-14 The receiving unit 3 and the storage unit 22 can be arranged at different distances from each other, in particular at different horizontal distances as shown. In particular, a different distance allows the product 2 to be transferred from the receiving unit 3 to the storage unit 22, as shown in the Figures 3-5shown, or from storage unit 22 to recording unit 3, as shown in the Figures 6-10 can be represented and transported.

[0059] The recording unit 3 and the storage unit 22 have corresponding edge regions 26, wherein the recording unit 3 has an edge region 26a, and the storage unit 22 has an edge region 26b. The edge region 26a is arranged in the area of ​​a second pivoting device 14. The edge region 26b is arranged on the storage unit 22 opposite the first pivoting device 24.

[0060] The storage unit 22 comprises a first pivoting device 24 about which the storage unit 22 can be pivoted. In particular, a return element is provided on the first pivoting device 24, so that the storage unit 22 is self-resetting due to gravity. In the illustrated embodiment, the storage unit 22 is formed from an angled cantilever arm. The cantilever arm is specifically designed as a U-shaped retaining element, so that a product 2 can be held in the storage unit 22.

[0061] In Fig. 2 Two storage units 22 are provided, which are arranged on a common guide device 23. Consequently, two products 2 can be temporarily stored.

[0062] The Figures 3 to 5Figure 2 shows an embodiment of the storage device 21 during the dispensing of a product 2 to the storage unit 22, with the storage unit 22 and the receiving unit 3 visible in a cross-section. The storage unit 22 is designed as a cantilever arm, which is mounted on the pivot axis 25. The storage unit 22 has a U-shaped retaining element. The U-shaped retaining element forms a support surface for the product 2 and, in particular, has a recess for this purpose. This allows the product 2 to be securely held on the U-shaped retaining element. The recess can, for example, be V-shaped, so that the product 2 can be prevented from rolling to the right or left when the storage unit 22 is aligned due to gravity.

[0063] The delivery of product 2 into a storage unit 22 can be carried out as in the Figures 3 to 5 This will be shown.

[0064] First, the recording unit 3 is pivoted upwards so that it can contact the storage unit 22. As in Figure 3 As shown, the receiving unit 3 rotates around the second pivoting device 14. In particular, the receiving unit 3 can be pivoted upwards from the home position by 90° to 120°, preferably 110°.

[0065] As in Figure 4As shown, the edge regions 26a and 26b make contact, forming a first inclined plane 27. This first inclined plane 27 has an angle such that the product 2 can roll or slide from the receiving unit 3 into the storage unit 22. If the product 2 is not cylindrical, it can also slide or slide on the inclined plane 27. Upon contact of the edge regions 26a and 26b, the storage unit 22 can be deflected to the right in the illustration. This allows the desired first inclined plane 27 to be reached in the first position.

[0066] When the product 2 is located on the storage unit 22, and the receiving unit 3 is pivoted back into its initial position as shown in Figure 3, the storage unit 22 automatically aligns itself due to gravity, securely holding the product 2 within it. In particular, the geometry of the cantilever arm, as shown, is formed from mutually angled surfaces, forming, in particular, a U-shaped retaining element. Secure placement is facilitated by the return of the storage unit 22 by a return element provided on the first pivoting device 24. Furthermore, the center of gravity of the storage unit 22 is specifically aligned with respect to a pivoting axis 25 to optimize the return to its initial position.

[0067] Contact surfaces 29a, 29b are provided at the edge regions 26a, 26b, so that the storage unit 22 and the receiving unit 3 can support each other. The contact surfaces 29a, 29b can be designed as chamfered areas of the storage unit 22 and the receiving unit 3, respectively. Several contact areas 29a, 29b can be provided at intervals between each edge region 26a, 26b.

[0068] After product 2 has been placed in storage unit 22, another product 2 can be placed in receiving unit 3. If storage unit 22 is then displayed as shown in the diagram... Figure 5 If moved to the right, the further product 2 can be transferred to the storage unit 22 on the left in the illustration.

[0069] The Figures 6 to 10 show the discharge of a product 2 from storage unit 22 into discharge unit 3.

[0070] For example, the receiving unit 3 and the storage unit 22 for removing the product 2 from the combination machine are arranged at a distance, in particular a horizontal distance, from each other, which does not correspond to the distance shown in the Figures 3 to 5 As shown, the desired distance can be achieved by moving the recording unit 3 and / or the storage unit 22 horizontally. For example, the recording unit 3 can be moved linearly to the right, in particular by 30 mm to 80 mm, preferably by 40 mm to 70 mm, and in particular by 60 mm, as shown in Figure 7 The distances shown are particularly advantageous when the recording unit 3 is swivelled upwards.

[0071] In another embodiment, the recording unit 3 and the storage unit 22 can be arranged at the same distance from each other as in the Figures 3 to 5A second inclined plane 28 is achieved in such an embodiment solely by the rotation angle in which the receiving unit 3 is pivoted.

[0072] In both described cases, the recording unit 3 can be pivoted upwards by 70° to 90°, in particular by 80°. In particular, the pivot angle is smaller than in the process of Figures 3 to 5 In particular, the receiving unit 3 can be displaced linearly to the right, in particular by 30 mm to 80 mm, preferably by 40 mm to 70 mm, and in particular by 40 mm to 60 mm. Depending on the angle of rotation, and in particular depending on the linear movement, a second inclined plane 28 can be formed, which has a gradient opposite to that of the first inclined plane 27, as shown by the dashed line in Figure 9 depicted.

[0073] When products 2 are removed from the combination vending machine, the edge areas 26a and 26b also make contact, causing the storage unit 22 to be deflected at a desired angle around the axis of rotation 25. After the second inclined plane 28 is set, the product 2 can slide, slid, or roll from the storage unit 22 to the receiving unit 3, depending on the geometry of the product 2. Once the product 2 has reached the receiving unit 3, the receiving unit 3 can be moved linearly in the opposite direction as described above, i.e., to the left in the illustration, as shown in Figure 10As shown. Simultaneously or subsequently, the receiving unit 3 can be pivoted back downwards to its home position, thereby losing contact with the storage unit 22. The storage unit 22 can therefore return to its initial position, in particular by means of a return element on the first pivoting device 24. Once the product 2 is again on the receiving unit 3, it can either be removed from the vending machine by the customer or sorted into corresponding chutes or receiving containers within the vending machine.

[0074] The Figures 11 to 14Figure 1 shows a possible embodiment of the transport unit 5 of the receiving unit 3 mounted on guide rails 11. The overall system shown can be referred to as a receiving device 1. The guide rails 11 are arranged parallel to each other, with the front guide rail in the figures being located closer to an input opening. The input opening 4 is, for example, located in Figure 15 The diagram illustrates the position of the guide rails 11 in the combination vending machine 19. The guide rails 11 allow the transport unit 5 to be moved towards the input opening 4, enabling the insertion of a product 2 onto the receiving unit 3. Furthermore, the transport unit 5 can be moved perpendicular to the input opening 4 to discharge the product 2 at any position inside or outside the machine. The directions of travel are indicated by the arrows in the diagram. Figure 9 and Figure 10 depicted.

[0075] The Figures 13 and 14 Figure 12 shows a guide contour 12, which can be provided between the two guide rails 11. The guide contour 12 can be formed integrally with a guide rail 11. Alternatively, the guide contour 12 can be welded or screwed to the guide rail 11. In particular, the guide contour 12 is designed as a component that has a side edge that is at least partially semicircular. The guide pin 13 can be guided along this side edge, thereby triggering a movement of the receiving unit 3. The guide pin 13 is therefore arranged on the receiving unit 3 so that the receiving unit 3 can be moved towards the input opening 4 when the guide pin contacts the guide contour, and the transport unit 5 is moved along the guide rails 11.

[0076] Advantageously, a movement of the transport unit 5 in a first direction of movement can trigger a movement of the receiving unit 3 in a second direction of movement. The two directions of movement are specifically perpendicular to each other. This allows the product 2 to be moved both towards the input opening 4 and at least partially through the input opening 4. This ensures simple and ergonomic removal and insertion of the product.

[0077] As in Figure 14 As shown, the product 2 extends beyond the guide rail 11 when the transport unit 5 is arranged on a side area where the guide contour 12 is located.

[0078] Fig. 15Figure 1 shows an embodiment of the combination vending machine 19 with a storage device 21. Detail view A shows the interior of the combination vending machine 19 in the area of ​​the input opening 4. The receiving unit 3 is visible here. In this illustration, the receiving unit 3 is located, for example, in the position shown in Figure 2. Figure 14 As shown, the receiving unit 3 allows the product 2 to be moved towards a front side 20 of the combination machine 19, thereby bringing it closer to the input opening 4. The ability to move the receiving unit 3 relative to the transport unit 5 also allows the product 2 to be moved away from the input opening 4 and subsequently transferred to the storage unit 22 at any desired position within the combination machine 19. This position can be reached via guide rails 11, along which the transport unit 5 can be moved.

[0079] The combination vending machine 19 may also have an output opening 30, which is provided in addition to the input opening 4.

[0080] Inside the vending machine 19, a storage unit 22 can be provided, which is not accessible from the outside. The storage unit 22 enables targeted temporary storage of the products 2 within the machine, particularly when fewer products are dispensed from the machine than are placed into it.

[0081] Although the present invention has been fully described above with reference to preferred embodiments, it is not limited thereto, but can be modified in many ways.

[0082] For example, sensors or at least a light barrier can be provided to detect what type of product has been placed in the receiving unit 3. The detected product 2 can then be sorted selectively or, if necessary, rejected. This allows, for example, the detection of an incorrectly inserted product or even waste, which should therefore not be introduced into the combination vending machine 19.

[0083] In another embodiment, a product detected incorrectly can, for example, be dispensed downwards. The swiveling device 14 therefore allows for sorting, whereby a selection of products is dispensed upwards, and another selection of products downwards, through an opening 6 in the receiving device 1 as shown in Fig. 1 They can be shown and handed in. Individual products can also be disposed of in a waste container, for example.

[0084] In another embodiment, the number of storage units 22 can be expanded as desired, and the number of cached products 2 can also be increased.

[0085] The storage unit 22 is particularly suitable for the intermediate storage of CO2 cylinders, but can also be used for deposit bottles, glass bottles, PET bottles or products and containers in general.

[0086] In particular, the storage unit 22 does not require its own drive, as it is mechanically operated by contact with the receiving unit 3. In a further embodiment, a drive, for example electric, pneumatic or hydraulic, can also be provided for the storage unit 22, so that it can also be operated independently of the receiving unit 3.

[0087] In particular, the position of the center of gravity of the storage unit 22 with respect to the axis of rotation 25 has a beneficial effect on self-resetting by gravity. Specifically, the geometry of the receiving unit 3 and the storage unit 22 is designed such that a transfer can be carried out smoothly, reliably, and without obstruction during both the storage and retrieval processes. In particular, different rotation angles can be implemented, and these rotation angles are not limited to the previously mentioned angular ranges. Furthermore, any linear displacement of the storage unit 22 relative to the receiving unit 3 can occur. In particular, the sequence can be varied, allowing the movement and rotation to be performed arbitrarily consecutively. For example, when retrieving products 2, a movement, i.e.,In particular, a linear movement will not occur, and only a pivoting will take place.

[0088] In a further embodiment, stops, in particular mechanical stops, can be provided to limit the rotation angles of the storage unit 22 and / or the recording unit 3, particularly in both directions of rotation. This can prevent, in particular, any oscillation or rebound of the storage unit 22.

[0089] In general, this offers the advantage of enabling the combined dispensing of several products 2. This allows the vending machine to accept multiple products without having to dispense any product 2 in between. Specifically, the number of products 2 that can be returned in a single batch is determined by the number of storage units 22 in the vending machine 19.

[0090] For example, items that should not be accepted, but were left behind by a customer in the receiving unit 3, can also be sorted into storage device 21.

[0091] Overall, a cost-effective implementation of a storage device 21 can be provided, which can be implemented with only a few components. Therefore, integration into existing combination vending machines 19, such as CO2 combination vending machines in particular, can be achieved cost-effectively and with few components.

[0092] Overall, the stepless movement options enable gentle handling of the products 2, and the storage device 21 is also suitable for glass bottles. Reference symbol list
