Description

Technical Field

[0001] Embodiments of the present invention generally relate to vending machines, and more specifically, to vending machines that present vended products to consumers without dropping the vended products.

Background Art

[0002] Vending machines are used to store products (such as beverages in bottles, cans, boxes, etc.) and deliver them to consumers. Many conventional vending machines deliver products by allowing consumers to open, for example, a hinged door and drop the products into a receiving space where the products are taken out. Other vending machines do not drop the products, but these vending machines require a high level of repair and maintenance.

Summary of the Invention

Means for Solving the Problems

[0003] In some embodiments, the vending machine includes two horizontal feed screws, a first and a second motor, a vertical feed screw, a shelf, a dispensing cup, and a dispensing area. In some embodiments, the first motor is connected to and drives the two horizontal feed screws. In some embodiments, the vertical feed screw moves horizontally along the two horizontal feed screws. In some embodiments, the second motor is connected to and drives the vertical feed screw. In some embodiments, the shelf has a movable gate that houses and holds the vending products thereon. In some embodiments, the dispensing cup is connected to the vertical feed screw and moves vertically along the vertical feed screw. In some embodiments, the dispensing cup has a solenoid and a plunger. In some embodiments, the solenoid actuates the plunger, and the plunger opens the gate to dispense the vending product onto the dispensing cup. In some embodiments, the dispensing area has an outer door. In some embodiments, the outer door isolates the dispensing area from the outside of the vending machine when in the closed position and provides access to the vending product from the outside of the vending machine through an opening when in the open position. In some embodiments, the mechanical interaction between the dispensing cup and the dispensing area moves the outer door to the open position.

[0004] In some embodiments, the first motor is disposed adjacent to the second motor. In some embodiments, the first and second motors are disposed outside the storage space of the vending machine. In some embodiments, the vending machine includes a transparent front panel.

[0005] In some embodiments, the dispensing cup includes a container having an open side that faces the shelf and receives the vending product. In some embodiments, the mechanical interaction between the dispensing cup and the dispensing area rotates the dispensing cup so that the open side is aligned with the opening. In some embodiments, the mechanical interaction rotates the dispensing cup and simultaneously opens the outer door. In some embodiments, the vending machine also includes a rack and a pinion gear. In some embodiments, the mechanical interaction includes an interaction between the rack and the pinion gear.

[0006] In some embodiments, the gate comprises two side gates mechanically linked to the front panel. In some embodiments, the plunger presses the front panel to open the two side gates. In some embodiments, the vending machine also includes a spring that closes the two side gates. In some embodiments, the vending machine also includes an optical sensor that detects when the gate is fully open and provides a signal to the solenoid.

[0007] In some embodiments, the shelf is flat. In some embodiments, the vending machine also includes an ultrasonic sensor disposed on the dispensing cup. In some embodiments, the ultrasonic sensor detects the vended product within the dispensing cup.

[0008] In some embodiments, the vending machine includes an external body, a storage space within the external body, a dispensing system, and a dispensing area. In some embodiments, the storage space stores the vended products. In some embodiments, the dispensing system is movable in the X and Y directions. In some embodiments, the dispensing system has a container with an open side and a pinion gear mechanically linked to the container. In some embodiments, the dispensing area has a rack, an outer door, and a protrusion mechanically linked to the outer door and protruding through a slot. In some embodiments, the outer door isolates the dispensing area from the outside of the external body in the closed position and provides access to the vended products from the outside of the external body in the open position. In some embodiments, the surface of the dispensing system pushes the protrusion along the slot as the dispensing system moves the vended product into the dispensing area, thereby moving the outer door from the closed position to the open position. In some embodiments, the rack interacts with the pinion gear as the dispensing system moves the vended product into the dispensing area, thereby rotating the container so that the open side faces the opening formed when the outer door is in the open position.

[0009] In some embodiments, the slot is curved and the outer door moves in a rotational manner. In some embodiments, the vending machine also includes an inner door between the dispensing area and the storage space. In some embodiments, the dispensing system mechanically opens the inner door.

[0010] In some embodiments, a method for selling products from a vending machine to a consumer includes moving a dispensing cup to align the dispensing cup with a shelf that houses the product, opening the gate of the shelf by activating a solenoid for a timed pulse, receiving the product into the dispensing cup, and moving the dispensing cup into the dispensing area so that the product is presented to the consumer in an upright manner. In some embodiments, moving the dispensing cup into the dispensing area mechanically opens the outer door to allow access to the dispensing area and mechanically rotates the dispensing cup to provide consumer access to the product. In some embodiments, the vending machine includes a transparent front panel.

[0011] In some embodiments, the method also includes closing the gate with a spring after the timed pulse. In some embodiments, the timed pulse allows only one product to be dispensed from the shelf. In some embodiments, the method also includes unlocking and opening the inner door with respect to the dispensing area.

[0012] In some embodiments, the method also includes removing the dispensing cup from the dispensing area after the product has been removed by the consumer. In some embodiments, removing the dispensing cup from the dispensing area closes the outer door and closes and locks the inner door. In some embodiments, the transparent front panel includes glass.

Best Mode for Carrying Out the Invention

[0043] Hereinafter, the present invention will be described in detail with reference to embodiments of the present invention as illustrated in the accompanying drawings. References to "one embodiment", "an embodiment", "an exemplary embodiment", etc. indicate that the described embodiments may include certain features, structures, or characteristics, but not all embodiments necessarily include the certain features, structures, or characteristics. Further, such phrases do not necessarily refer to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, whether or not explicitly described, the impact of such feature, structure, or characteristic on other embodiments is within the knowledge of those skilled in the art.

[0044] Vending machines are used to store products (e.g., beverages in bottles, cans, boxes, etc.) and dispense them to consumers. Many conventional vending machines dispense products by having the consumer, for example, open a hinged door and drop the product into a receiving space where the product can be retrieved. However, seeing and / or hearing the product drop can be unpleasant for the consumer. Additionally, dropping some products (e.g., carbonated beverages) can cause them to fizz when the product is opened. Presenting the product to the consumer rather than dropping it will improve the quality of the product and make it more user-friendly.

[0045] Some vending machines do not drop the product, but these vending machines require a high level of repair and maintenance. Therefore, it is desirable to provide a vending machine that presents the product to the consumer while reducing the complexity of other vending machines (i.e., a waste-free vending machine). Further, it is desirable for the vending machine to accommodate products of various shapes (e.g., cylindrical, square) and sizes while providing simple product loading.

[0046] Accordingly, in some embodiments, a waste-free vending machine includes a storage system, a dispensing system, and a dispensing area. These components interact with each other to distribute, transport, and present the vended product to the consumer without dropping it at all. In some examples, this interaction is primarily mechanical, so the vending machine is simplified and the need for repair and maintenance is reduced.

[0047] In some embodiments, the storage system is modular. In some embodiments, the storage system includes one or more shelves. In some embodiments, the plurality of shelves form a grid-like product storage area. In some embodiments, each shelf is configured to dispense a product for sale. For example, each shelf may include a mechanism such as a spring-loaded product pusher for dispensing a product for sale. As another example, each shelf may be inclined downward so that gravity assists and / or draws the product for sale out of the shelf. In some embodiments, each shelf is flat. In some embodiments, each shelf includes a gate that holds the product for sale on the shelf until the vending machine is ready to dispense the product for sale.

[0048] In some embodiments, the dispensing system includes an X-Y mechanism and a dispensing cup. In some embodiments, the X-Y mechanism moves the dispensing cup in the X and Y directions, enabling the dispensing cup to be positioned adjacent to a shelf to receive a product for sale and then repositioned to a dispensing area to present the product for sale to a consumer. In some embodiments, the X-Y mechanism includes a lead screw and a nut assembly.

[0049] In some embodiments, the dispensing cup is coupled to the X-Y mechanism and includes a platform for supporting a product for sale. In some embodiments, the dispensing cup communicates with the shelf. In some embodiments, the dispensing cup communicates with the shelf to properly position the dispensing cup. In some embodiments, the dispensing cup interacts with the shelf to open a gate, enabling one of the products for sale to be dispensed onto or into the dispensing cup. For example, the dispensing cup may include an actuator for opening the gate. In some embodiments, the dispensing cup opens the gate by using a solenoid that actuates a plunger.

[0050] In some embodiments, the dispensing area includes a pick-up location for a consumer to retrieve the sold product. In some embodiments, the dispensing area includes an outer door that isolates the dispensing area from the outside of the vending machine. In some embodiments, the dispensing cup mechanically interacts with the dispensing area when the dispensing cup enters the dispensing area to provide the consumer with access to the sold product and thus present the sold product to the consumer. In some embodiments, the mechanical interaction rotates the dispensing cup, opens the inner door, unlocks the inner door, and / or opens the outer door of the dispensing area. In some embodiments, the mechanical interaction includes an interaction between a pinion gear and a rack. In some embodiments, the mechanical interaction includes an interaction between a push surface and a protrusion protruding through a slot. In some embodiments, the mechanical interaction includes an interaction between the protrusion and a locking mechanism. In some embodiments, the mechanical interaction includes a direct force on the inner door.

[0051] Sold products can include beverages such as bottled water, energy drinks, carbonated soft drinks, milk, juice, sports drinks, and foods such as chips, granola bars, energy bars, sandwiches, ice cream bars, candy, and other snacks. The sold products can be packaged in different sizes, shapes, and styles. Thus, while beverages are mainly considered herein, the disclosed principles are equally applicable to other types of sold products. The waste-free vending machine disclosed herein can be used in any environment (e.g., school campus, store, mall, office, etc.).

[0052] These and other examples are considered below with reference to the drawings. However, those skilled in the art will understand that the detailed description provided herein with respect to these drawings is for illustrative purposes only and should not be construed as limiting.

[0053] In some embodiments, the vending machine 10 includes an external body 14, as shown in FIG. 1 for example. The external body 14 may be made of a plurality of parts (such as side panels, rear panels, front panels, upper panels, or bottom panels, etc.), or may be structured by any method known in the art without departing from the present invention. In some embodiments, the vending machine 10 includes a front panel 16. In some embodiments, the front panel 16 is transparent. In some embodiments, the front panel 16 is glass (for example, single or double-layered). In some embodiments, the front panel 16 is transparent plastic. In some embodiments, the front panel 16 is sized and shaped to allow a consumer to view the vended product 12 stored within the vending machine 10.

[0054] In some embodiments, the vending machine 10 includes a user interface 18. In some embodiments, the user interface 18 includes, for example, a keypad and / or a touch screen that can be used to select a desired vended product 12 or enter information (such as a PIN number, etc.). In some embodiments, the user interface 18 includes a payment mechanism. For example, the user interface 18 may include one or more of a currency receiving area (such as a bill and / or coin slot), a card reader (such as a swipe for credit cards, debit cards, ID cards, etc.), and a contactless payment mechanism (such as a mechanism based on RFID, QR code (registered trademark), NFC, Bluetooth (registered trademark), etc.). In some embodiments, the user interface 18 includes a payment return mechanism such as bill and / or coin return. In some embodiments, the user interface 18 is disposed adjacent to the front panel 16. In some embodiments, the user interface 18 is surrounded by a plastic cover 19.

[0055] In some embodiments, the vending machine 10 is used to sell one or more sales products 12. In some embodiments, each of the sales products 12 may be of the same type of product (e.g., bottled water). In some embodiments, the vending machine 10 may include various sales products 12 (e.g., bottled water, different flavors of soft drinks, juices, etc.).

[0056] In some embodiments, the vending machine 10 includes a storage space 20. For example, the storage space 20 may be located within the external body 14. In some embodiments, the storage space 20 includes a space visible through the front panel 16. In some embodiments, the vending machine 10 stores the sales products 12 within the storage space 20. For example, the vending machine 10 may store the sales products 12 on a plurality of shelves 300 within the storage space 20. In some embodiments, each shelf 300 may be dedicated to a particular type of sales product 12.

[0057] In some embodiments, the vending machine 10 includes a delivery area 400. In some embodiments, the delivery area 400 is configured to present the sales product 12 to the consumer. In some embodiments, the delivery area 400 is surrounded by a plastic cover 19. In some embodiments, the delivery area 400 is disposed adjacent to (e.g., below) the user interface 18. In some embodiments, the delivery area 400 includes an outer door 410. The outer door 410, when closed, may isolate the delivery area 400 from the outside of the vending machine 10.

[0058] In some embodiments, for example, as shown in FIG. 2, the vending machine 10 includes a delivery system 100 for transporting the vending product 12 from the shelf 300 to the delivery area 400. In some embodiments, the delivery system 100 is disposed between the front panel 16 and the shelf 300. In some embodiments, the delivery system 100 includes an X-Y mechanism and a delivery cup 200. In some embodiments, the X-Y mechanism of the delivery system 100 moves the delivery cup 200 to any position within its plane in the storage space 20, and thus enables the delivery cup 200 to be positioned adjacent to any of the plurality of shelves 300 and within the delivery area 400.

[0059] In some embodiments, the X-Y mechanism of the delivery system 100 is attached to the vending machine 10 via a support bracket 102. In some embodiments, the support bracket 102 can be disposed at the corner of the X-Y mechanism. In some embodiments, the X-Y mechanism includes a support rod 104 that provides additional support for fixing the X-Y mechanism within the vending machine 10. In some embodiments, the support rod 104 can be disposed near the top of the vending machine 10.

[0060] In some embodiments, the X-Y mechanism of the delivery system 100 includes a system of lead screws and nut assemblies. In some embodiments, the nut assembly includes a component (e.g., a bracket) that attaches the lead screw to an element (e.g., the delivery cup 200, another lead screw, etc.) that is to be moved along the lead screw. The component can be screwed into an internal portion such that when the lead screw rotates, the component moves along the lead screw. Hereinafter, this relationship is referred to as a nut configuration.

[0061] In some embodiments, the X-Y mechanism includes a bottom horizontal feed screw 105, an upper horizontal feed screw 110, and a vertical feed screw 120. In some embodiments, the bottom horizontal feed screw 105 is disposed near the bottom of the vending machine 10. In some embodiments, the bottom horizontal feed screw 105 is disposed under the bottom of the front panel 16 and is out of the consumer's view. In some embodiments, the upper horizontal feed screw 110 is disposed near the upper part of the vending machine 10. In some embodiments, the upper horizontal feed screw 110 is disposed above the upper part of the front panel 16 and is out of the consumer's view. In some embodiments, the upper horizontal feed screw 110 is connected to a motor 114 and is driven by the motor 114 (see FIG. 3). In some embodiments, the motor 114 is disposed in a motor box 130. In some embodiments, the motor 114 includes a DC motor. In some embodiments, the bottom horizontal feed screw 105 is also connected to the motor 114 and is driven by the motor 114. In some embodiments, the bottom horizontal feed screw 105 is indirectly connected to the motor 114.

[0062] In some embodiments, the movement of the upper horizontal feed screw 110 is transmitted to the bottom horizontal feed screw 105 via the transmission rod 112. For example, as shown in FIG. 4, the transmission gear 111 can be connected to the upper horizontal feed screw 110, and the transmission gear 113 can be connected to the transmission rod 112. When the upper horizontal feed screw 110 rotates, the transmission gear 111 can engage with the transmission gear 113 so that the transmission rod 112 also rotates. As shown in FIG. 6, the transmission gear 109 can be connected to the transmission rod 112, and the transmission gear 107 can be connected to the bottom horizontal feed screw 105. When the transmission rod 112 rotates, the transmission gear 109 can engage with the transmission gear 107 so that the bottom horizontal feed screw 105 also rotates. In some embodiments, the upper horizontal feed screw 110 and the bottom horizontal feed screw 105 rotate at the same speed. For example, the gear ratio between the transmission gear 111 and the transmission gear 113 can be 1:1, and the gear ratio between the transmission gear 109 and the transmission gear 107 can also be 1:1. In some embodiments, the transmission rod 112 is disposed on the side of the vending machine 10 opposite to the delivery area 400. In some embodiments, the transmission rod 112 is disposed on the left side of the front panel 16 and is out of the consumer's sight.

[0063] In some embodiments, the vertical feed screw 120 is connected in a nut configuration to the upper horizontal feed screw 110 and the bottom horizontal feed screw 105, as shown, for example, in FIGS. 5 and 7, such that when the upper horizontal feed screw 110 and the bottom horizontal feed screw 105 rotate, the vertical feed screw 120 moves along the upper horizontal feed screw 110 and the bottom horizontal feed screw 105. In some embodiments, the vertical feed screw 120 is connected to the motor 124 (see FIGS. 2 and 3). In some embodiments, the vertical feed screw 120 is indirectly connected to the motor 124 via the transmission rod 122. For example, as shown in FIG. 5, the transmission gear 121 may be connected to the transmission rod 122, and the transmission gear 123 may be connected to the vertical feed screw 120. The transmission gear 121 may engage the transmission gear 123 such that when the transmission rod 122 rotates, the vertical feed screw 120 also rotates. In some embodiments, the transmission rod 122 is disposed adjacent to the upper horizontal feed screw 110. Thus, in some embodiments, the transmission rod 122 is disposed above the upper portion of the front panel 16 and is removed from the consumer's field of view. In some embodiments, the transmission rod 122 is square.

[0064] In some embodiments, motor 124 is disposed adjacent to motor 114. In some embodiments, motor 124 is disposed within motor box 130. In some embodiments, motor 124 includes a DC motor. In some embodiments, motor box 130 includes a sound insulating body 132 as shown in FIG. 3 with motor box 130 removed. In some embodiments, sound insulating body 132 can reduce the noise of motors 114 and 124 that can be heard by a consumer. In some embodiments, motor box 130 is disposed so as to be out of the consumer's field of view. For example, motor box 130 can be disposed at the upper right corner (i.e., to the right and / or above the edge of front panel 16). Thus, in some embodiments, motor box 130 can be disposed outside storage space 20. In some embodiments, motors 114 and 124 are controlled by a controller. For example, motors 114 and 124 can receive a signal from the controller and move dispensing cup 200 a certain amount in the X direction and a certain amount in the Y direction. The signal from the controller can be based on the selection of a particular sales product 12 by the consumer via user interface 18. The controller can be a single controller that controls both motors 114 and 124, or two separate controllers that control motors 114 and 124 separately.

[0065] In some embodiments, support beam 140 is connected to vertical feed screw 120. In some embodiments, support beam 140 operates to provide additional structural support to vertical feed screw 120. In some embodiments, support beam 140 operates to hide a portion of the X-Y mechanism from the consumer's field of view (e.g., vertical feed screw 120, electrical connections, brackets, etc.).

[0066] In some embodiments, the delivery cup 200 of the delivery system 100 is coupled to the vertical feed screw 200 in a nut configuration, as shown, for example, in FIGS. 2 and 8, such that when the vertical feed screw 120 rotates, the delivery cup 200 moves along the vertical feed screw 120. Thus, the delivery cup 200 can move in the Y direction when the vertical feed screw 120 rotates and can move in the X direction when the upper horizontal feed screw 110 and the bottom horizontal feed screw 105 rotate (along with the vertical feed screw 120 and the support beam 140). Thus, the delivery cup 200 can be accurately and reliably positioned in any of the shelves 300 and the delivery area 400 based on signals received by a controller that controls the motors 114 and 124. In some embodiments, instead of a system of feed screws and nut assemblies, other types of X-Y mechanisms may be used to accurately position the delivery cup 200.

[0067] In some embodiments, the delivery cup 200 is configured to receive the sales product 12 from the shelf 300 and transport the sales product 12 to the delivery area 400. In some embodiments, the delivery cup 200 is configured to interact with the shelf 300. In some embodiments, the delivery cup 200 may communicate with the shelf 300 and vice versa. For example, the shelf 300 may send a signal to the delivery cup 200 indicating that the delivery cup 200 has arrived at the appropriate location. As another example, the delivery cup 200 may send a signal to the shelf 300 indicating that the delivery cup 200 is ready to receive the sales product 12. The signal between the delivery cup 200 and the shelf 300 may utilize, for example, RFID, NFC, or Bluetooth® technology. In some embodiments, the delivery cup 200 may include an actuator that causes the shelf 300 to dispense the sales product 12. In some embodiments, the actuator includes a mechanical actuator.

[0068] In some embodiments, the delivery cup 200 is configured to interact with the delivery area 400. In some embodiments, the interaction between the delivery cup 200 and the delivery area 400 enables a consumer to easily access the sold product 12 within the delivery area 400. In some embodiments, the interaction between the delivery cup 200 and the delivery area 400 opens the outer door 410. In some embodiments, the delivery cup 200 is configured to mechanically interact with the delivery area 400. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 causes the outer door 410 to open. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 results in the movement of other components of the delivery area 400 and / or the delivery cup 200 that provides the consumer with better access to the sold product 12. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 effectively presents the sold product 12 to the consumer.

[0069] In some embodiments, for example, as shown in FIGS. 8-10, the delivery cup 200 includes a container 210 and a base 220. In some embodiments, the container 210 is transparent, enabling a consumer to view the sold product 12 as it is transported to the delivery area 400. In some embodiments, the container 210 has an open side 212. In some embodiments, the open side 212 is configured to face the shelf 300. In some embodiments, the container 210 is configured to rotate relative to the base 220. For example, as more fully described below, the container 210 can rotate 180 degrees as it enters the delivery area 400 such that the open side 212 faces the consumer, thus facilitating consumer access to the sold product 12.

[0070] In some embodiments, the base 220 supports the container 210. In some embodiments, the base 220 includes features that facilitate consumer access to the vending product 12. These features may include an extrusion surface 222, a protrusion 224, and / or a pinion gear 226 (see FIG. 10). In some embodiments, the extrusion surface 222 can open the outer door 410 as more fully described below. In some embodiments, the protrusion 224 can unlock the inner door 420 of the dispensing area 400 as more fully described below. In some embodiments, the pinion gear 226 can interact with the rack 430 of the dispensing area 400 to rotate the container 210 as more fully described below. Thus, in some embodiments, the pinion gear 226 is coupled to the container 210 such that rotation of the pinion gear 226 is linked to rotation of the container 210.

[0071] In some embodiments, the dispensing cup 200 includes a sensor 230 that detects whether the vending product 12 is within the dispensing cup 200 (i.e., the sensor 230 can detect the presence or absence of the vending product 12 within the dispensing cup 200). In some embodiments, the sensor 230 includes an ultrasonic sensor. In some embodiments, the container 210 includes a hole 214 that facilitates detection of the vending product 12 by the sensor 230. In some embodiments, the container 210 includes two holes 214 on both sides such that the sensor 230 can detect when the vending product 12 is received from the shelf 300 (i.e., before rotating 180 degrees) and when the vending product 12 is removed by a consumer within the dispensing area 400 (i.e., after rotating 180 degrees).

[0072] In some embodiments, the movement of the dispensing cup 200 may be based on a sensor 230 that detects the presence (or absence) of the sold product 12. For example, the dispensing cup 200 may remain within the dispensing area 400 until the absence of the sold product 12 (indicating that the consumer has removed the sold product 12) is detected. As another example, the dispensing cup 200 may remain beside the shelf 300 until the sold product 12 is detected (indicating that the sold product 12 is ready to be transported to the dispensing area 400). In some embodiments, instead of the sensor 230, different types of sensors may be used at the same or different positions. For example, a pressure sensor may be used to detect the presence of the sold product 12 based on the weight of the container 210 and anything therein.

[0073] In some embodiments, the dispensing cup 200 includes features that facilitate the dispensing of the sold product 12 from the shelf 300. For example, as discussed above, the dispensing cup 200 and the shelf 300 may transmit signals to communicate that the dispensing cup 200 is properly positioned relative to the shelf 300. In some embodiments, the dispensing cup 200 may include an actuator. In some embodiments, the actuator may transmit a signal to the shelf 300 to dispense the sold product 12. In some embodiments, the signal may be transmitted via RFID, NFC, or Bluetooth® technology. In some embodiments, the actuator may include a mechanical actuator. In some embodiments, the actuator includes, for example, a solenoid 240 and a plunger 242 as shown in FIG. 10. In some embodiments, the solenoid 240 actuates the plunger 242. In some embodiments, when the plunger 242 is actuated, the plunger 242 interacts with the shelf 300 to enable the shelf 300 to dispense one sold product 12 into the dispensing cup 200, as more fully described below. In some embodiments, the solenoid 240 actuates the plunger 242 in response to a timed pulse.

[0074] In some embodiments, for example, as shown in FIG. 11, the shelf 300 includes a product storage area 305, a product pusher 310, and a gate 320. Although FIG. 11 shows only one shelf 300, the vending machine 10 may accommodate a plurality of shelves 300. In some embodiments, the shelf 300 is modular. In some embodiments, the shelf 300 may be positioned within a grid (i.e., adjacent shelves 300 are arranged in a row and multiple rows of shelves 300 are arranged vertically). In some embodiments, the product storage area 305 is configured to receive various sales products 12 having different shapes and sizes. In some embodiments, the sales product 12 is loaded into the product storage area 305 by pushing the sales product against the product pusher 310 and through the gate 320.

[0075] In some embodiments, the product pusher 310 is configured to slide along the shelf 300 via a sliding member 312, as shown, for example, in FIG. 12. In some embodiments, the sliding member 312 can slide along the rail 302 of the shelf 300, as shown, for example, in FIG. 13. As shown in FIG. 12, the product pusher 310 can be biased to the front portion of the shelf 300. When the sale product 12 is inserted into the product storage area 305, the product pusher 310 is pushed toward the rear of the shelf 300. In some embodiments, the product pusher 310 is spring-loaded and thus attempts to push the sale product 12 out of the product storage area 305. For example, the product pusher 310 can be biased to the front of the shelf 300 using a spring 314 (see FIGS. 14 and 15). In some embodiments, the spring 314 includes a constant load spring. When the product pusher 310 is in front of the shelf 300, the spring 314 can be fully wound up. When the sale product 12 is inserted into the product storage area 305, the product pusher 310 is pushed back, thus expanding the spring 314. The expanded spring 314 exerts a force on the product pusher 310, which pushes the sale product 12. In some embodiments, the shelf 300 is flat or horizontal; for example, the shelf 300 can be parallel to the floor or the base of the vending machine 10. In some embodiments, the shelf 300 is angled downward toward the dispensing cup 200 (i.e., toward the front of the vending machine 10). Thus, gravity can also exert a force on the sale products 12 to move them out of the product storage area 305.

[0076] In some embodiments, the gate 320 operates to hold the vended product 12 within the product storage area 305. In some embodiments, the gate 320 includes two side gates 320 (see FIGS. 11 and 14-16). The gate 320 can be sized based on the smallest vended product 12 stored within the vending machine 10. Thus, the gate 320 can hold vended products 12 of any size within the product storage area 305. In some embodiments, the two side gates 320 are disposed on the sides of the shelf 300. For example, one side gate 320 can be disposed on each side of the shelf 300. In some embodiments, the two side gates 320 extend only partially inwardly from each side of the shelf 300. In some embodiments, the shelf 300 includes sensors, such as optical sensors, that determine the size of the vended products 12 within the product storage area 305.

[0077] In some embodiments, the gate 320 is hinge-type. In some embodiments, the gate 320 is spring-loaded to a closed position. For example, as shown in FIG. 13, a spring 325 can be included in the shelf 300 to maintain the gate 320 in the closed position. In some embodiments, the gate 320 is mechanically linked to a front plate 322, a bottom plate 324, and side rods 326 (see FIGS. 13 and 16). In some embodiments, the front plate 322 is disposed at the bottom of the front side of the shelf 300 facing the dispensing cup 200. In some embodiments, the front plate 322 is configured to be pushed into the shelf 300. In some embodiments, the plunger 242 of the dispensing cup 200 is configured to push the front plate 322 into the shelf 300. In some embodiments, when the front plate 322 is pushed, the bottom plate 324 and the side rods 326 are also pushed back. In some embodiments, the side rods 326 slide within slots 329. In some embodiments, a link 328 connects the side rods 326 to the gate 320. Thus, when the side rods 326 slide back within the slots 329, the link 328 is pulled back, and thus, the gate 320 is swung open.

[0078] In some embodiments, as soon as the front plate 322 is released, the front plate 322 returns to its original position due to the force exerted by the spring 325. In some embodiments, the gate 320 remains open for a length sufficient for one sold product 12 dispensed from the shelf 300. In some embodiments, the timed pulse of the solenoid 240 is long enough to allow one sold product 12 to be dispensed from the shelf 300. In some embodiments, the length of time of the timed pulse is variable and may be based on the size of the sold product 12. In some embodiments, the length of time of the timed pulse is the same for each sold product 12 regardless of size. In some embodiments, the timed pulse is less than 1 second (e.g., less than 0.2 - 0.5 seconds). In some embodiments, the shelf 300 includes an optical sensor configured to detect when the gate 320 is fully open. In some embodiments, the optical sensor is configured to send a signal to the solenoid 240. In some embodiments, the timed pulse begins when the solenoid 240 receives a signal that the gate 320 is fully open. Similar timing or timed pulses may occur in embodiments where the actuator is not a solenoid and plunger configuration.

[0079] In some embodiments, after the delivery cup 200 receives the sold product 12 from the shelf 300, the delivery cup 200 transports the sold product 12 to the delivery area 400. In some embodiments, the delivery area 410 includes an area where a consumer can retrieve the sold product 12. In some embodiments, for example, as shown in FIG. 17, the delivery area 400 includes an outer door 410 and an inner door 420.

[0080] In some embodiments, the outer door 410 comprises a door that isolates the dispensing area 400 from the exterior of the vending machine 10 when the outer door 410 is closed (i.e., in the closed configuration 450 (see FIG. 18A)). In some embodiments, when the outer door 410 is opened (i.e., in the open configuration 460 (see FIG. 18B)), an opening 462 is formed to allow a consumer to access the dispensing area 400 so that the vended product 12 can be retrieved. In some embodiments, the outer door 410 moves from the closed configuration 450 to the open configuration 460 by mechanically interacting with the dispensing cup 420. In some embodiments, the outer door 410 slides open. In some embodiments, the outer door 410 rotates open. In some embodiments, the outer door 410 opens in the direction 452 as shown in FIG. 18A. In some embodiments, the outer door 410 comprises a bottom plate 412 and a top plate 414. In some embodiments, the bottom plate 412 and the top plate 414 connect the outer door 410 to the dispensing area 400 by a rotatable attachment. In some embodiments, the attachment is spring-loaded to bias the outer door 410 to be in the closed configuration 450.

[0081] In some embodiments, for example, as shown in FIG. 19, the bottom plate 412 includes a protrusion 440 that projects into the dispensing area 400. In some embodiments, the protrusion 440 projects through a slot 442. In some embodiments, the slot 442 is curved. In some embodiments, the push surface 222 of the dispensing cup 200 is configured to push the protrusion 440 along the slot 442. In some embodiments, as the protrusion 440 moves along the slot 442, the outer door 410 opens.

[0082] In some embodiments, for example, as shown in FIG. 19, the rack 430 is disposed within the dispensing area 400 in a fixed manner. In some embodiments, the pinion gear 226 of the dispensing cup 200 is configured to interact with the rack 430 when the dispensing cup 200 enters the dispensing area 400. The teeth of the rack 430 can engage the teeth of the pinion gear 226, and thus rotate the pinion gear 226 as the dispensing cup 200 continues to move within the dispensing area 400. In some embodiments, the rotation of the pinion gear 226 rotates the container 210, and thus presents the sales product 12 to the consumer. In some embodiments, the interaction between the pinion gear 226 and the rack 430, as well as the interaction between the pushing surface 222 and the protrusion 440, occur substantially simultaneously. For example, these interactions may be simultaneous, or these interactions may have at least partially overlapping timing. Thus, in some embodiments, when the outer door 410 opens (enabling the consumer to view within the dispensing area 400), the container 210 rotates. These combined movements may be added to the effect or usability of presenting the sales product 12 to the consumer. For example, after the outer door 410 is at least partially opened, the consumer can view the completion of the rotation of the container 210 to present the sales product 12 to the consumer. In some embodiments, the sales product 12 rotates with the rotation of the container 210.

[0083] In some embodiments, the inner door 420 isolates the dispensing area 400 from the storage space 20 of the vending machine 10. In some embodiments, the inner door 420 includes a hinged door. In some embodiments, the inner door 420 opens into the dispensing area 400 in the direction 454, as shown in FIG. 18A. In some embodiments, the inner door 420 is pushed open by the dispensing cup 200. In some embodiments, the inner door 420 is latched. For example, the inner door 420 may include a latching mechanism 422, as shown in FIG. 19, for example. In some embodiments, the latching mechanism 422 prevents the inner door 420 from opening inwardly in the direction 454. In some embodiments, the latching mechanism 422 can be depressed to unlock the inner door 420. In some embodiments, the protrusion 224 of the dispensing cup 200 is configured to interact with the latching mechanism 422 when the dispensing cup 200 enters the dispensing area 400. In some embodiments, the protrusion 224 extends further (i.e., closer to the dispensing area 400) than the remainder of the dispensing cup 200. Thus, the protrusion 224 can unlock the inner door 420 by depressing the latching mechanism 422 before the dispensing cup 200 pushes the inner door 420 to open the inner door 420. In some embodiments, the inner door 420 may be unlocked via other mechanisms. For example, in some embodiments, the inner door 420 may be configured to unlock itself when the dispensing cup 200 approaches. In some embodiments, the dispensing cup 200 can transmit a signal to the inner door 420 using wireless communication technologies such as RFID, Bluetooth®, NFC, etc. when the dispensing cup approaches the dispensing area 400. Other interactions or mechanisms may also be used.

[0084] In some embodiments, the inner door 420 cannot be opened from within the dispensing area 400. In some embodiments, the inner door 420 acts as a tamper-resistant door to prevent theft. In some embodiments, the inner door 420 includes a horizontal shelf 424 (see FIGS. 20A and 20B) that prevents a person from depressing the latching mechanism 422 to unlock the inner door 420.

[0085] As the vending product 12 is presented to the consumer, the interaction between the dispensing cup 200 and the dispensing area 400, which unlocks and opens the inner door 420 and rotates the container 210, is shown in FIGS. 20A-20G. In some embodiments, the dispensing cup 200 moves in the dispensing cup entry direction 470, enters the dispensing area 400, and moves in the dispensing cup exit direction 472 to exit the dispensing area 400. In some embodiments, the inner door 420 is latched in the closed position as shown in FIG. 20A. In some embodiments, the horizontal shelf 424 may prevent a person from unlocking the inner door 420. In some embodiments, when the dispensing cup 200 approaches the inner door 420, the dispensing cup 200 unlocks the inner door 420 (e.g., via the protrusion 224, wireless communication, or other mechanism). In some embodiments, the dispensing cup 200 begins to push and open the inner door 420 as shown in FIG. 20B. In some embodiments, when the dispensing cup 200 enters the dispensing area 400 as shown in FIG. 20C, the pinion gear 426 (not visible in FIG. 20C) interacts with the rack 430. In some embodiments, as shown in FIGS. 20D-20G, the interaction between the pinion gear 426 and the rack 430 as the dispensing cup 200 continues to enter the dispensing area 400 rotates the container 210 in the rotational direction 480 of opening the dispensing cup. In some embodiments, the total possible rotation includes 180 degrees. In some embodiments, the rotational direction 480 of opening the dispensing cup allows the open side 212 to rotate from facing away from the consumer (i.e., facing the shelf 300) to facing the consumer (see FIG. 20G). In some embodiments, when the dispensing cup 200 is withdrawn from the dispensing area 400, the interaction between the pinion gear 426 and the rack 430 rotates the dispensing cup 200 in the rotational direction 482 of closing the dispensing cup.

[0086] Accordingly, the vending machine 10 can be used to present the vended product 12 to the consumer in a sophisticated yet simple manner. In some embodiments, the consumer can make a payment for and select the vended product 12 via the user interface 18 (e.g., a keypad, a touch screen, and / or a payment mechanism). In some embodiments, the user interface 18 can include a keypad or a touch screen, a payment system (paper money, coins, cards, etc.), coin and / or paper money return, a display screen, and other similar components. In some embodiments, the selection of the vended product 12 at the user interface 18 can be communicated to a controller that controls the motors 114 and 124. In some embodiments, based on the communication to the controller, the motors 114 and 124 operate to rotate the upper horizontal feed screw 110, the bottom horizontal feed screw 105, and the vertical feed screw 120 such that the dispensing cup 200 moves in the X and Y directions to reach the appropriate shelf 300 for the selected vended product 12.

[0087] In some embodiments, the dispensing cup 200 moves to a preset location to receive the vended product 12. In some embodiments, the vending machine 10 knows when the dispensing cup 200 is in the correct location based on control from the controller of the motors 114 and 124. In some embodiments, the vending machine 10 knows when the dispensing cup 200 is in the correct location based on communication between the dispensing cup 200 and the shelf 300 (e.g., wireless communication technologies such as RFID, Bluetooth®, NFC, etc.).

[0088] In some embodiments, the dispensing cup 200 actuates the gate 320 of the shelf 300 to dispense one vended product 12 (e.g., via a wireless communication technology or via a mechanical actuator such as a solenoid 240 and a plunger 242). In some embodiments, the gate 320 remains open based on a time-limited pulse long enough to allow one vended product 12 to be dispensed from the shelf 300.

[0089] In some embodiments, the dispensing cup 200 detects when the sold product 12 is within the dispensing cup 200 (e.g., via a sensor 230 such as an ultrasonic sensor or via a pressure sensor). In some embodiments, the dispensing cup 200 transmits a communication to the controllers of motors 114 and 124 that the sold product 12 has been loaded onto the dispensing cup 200. In some embodiments, after the selected sold product 12 has been loaded into the dispensing cup 200, the controller drives motors 114 and 124 to rotate the upper horizontal feed screw 110, the bottom horizontal feed screw 105, and the vertical feed screw 120 so that the dispensing cup 200 moves in the X and Y directions to reach the dispensing area 400. In some embodiments, the dispensing cup 200 interacts with the dispensing area 400 to unlock and open the inner door 420, open the outer door 410, and rotate the container 210 (e.g., using the mechanisms described above). In some embodiments, combinations of these interactions present the sold product 12 to the consumer and provide access for the consumer to retrieve the selected sold product 12.

[0090] In some embodiments, the sold product 12 is presented to the consumer in an upright manner. In some embodiments, the sold product 12 is presented to the consumer without dropping. In some embodiments, the sold product 12 is presented to the consumer without the consumer having to open the outer door 410 or manually open or press any aspect of the vending machine 10 other than the user interface 18 (e.g., to select and pay for the sold product 12). In some embodiments, the sold product 12 is presented to the consumer by rotating the sold product 12.

[0091] In some embodiments, the dispensing cup 200 detects when the sold product 12 is removed from the dispensing cup 200 (e.g., via a sensor 230 such as an ultrasonic sensor or via a pressure sensor). In some embodiments, the dispensing cup 200 transmits a signal indicating that the product 12 has been removed to the controllers of the motors 114 and 124. In some embodiments, after the sold product 12 is removed, the controller drives the motors 114 and 124 to rotate the upper horizontal feed screw 110, the bottom horizontal feed screw 105, and the vertical feed screw 120 so that the dispensing cup 200 moves in the X and Y directions and returns to the starting position. In some embodiments, when the dispensing cup 200 exits the dispensing area 400, the outer door 410 is closed, the container 210 rotates to return to its starting position, and the inner door 420 is closed and locked.

[0092] In some embodiments, if the consumer does not remove the sold product 12 after a predetermined time has elapsed, the controller may drive the motors 114 and 124 to rotate the upper horizontal feed screw 110, the bottom horizontal feed screw 105, and the vertical feed screw 120 so that the dispensing cup 200 moves in the X and Y directions and returns to its starting position. When this occurs, the vending machine 10 may display that the sold product 12 has not been removed (e.g., via the user interface 18). The next consumer approaching the vending machine 10 (who sees this message) can use the user interface 18 to cause the vending machine 10 to dispense the loaded sold product 12 in the above manner before another sold product 12 is selected.

[0093] In some embodiments, for example, as shown in FIG. 21, the delivery area 400 includes a removal sensor 490, such as a hand presence sensor 490. The hand presence sensor 490 can ensure that the delivery cup 200 does not start moving while the consumer's removal is in progress, for example, while the consumer's hand is within the delivery area 400. For example, if the sensor 230 does not detect the sold product 12 (i.e., detects that the sold product 12 has been removed), the delivery cup 200 can start to return to the starting position as described above. Similarly, after a predetermined time has elapsed, even if the sold product 12 has not been removed, the delivery cup 200 can start to return to the starting position as described above. However, if the hand presence sensor 490 detects the consumer's hand within the delivery area 400 in any of these situations, the return of the delivery cup 200 to the starting position is delayed until the consumer's hand is no longer detected within the delivery area 400.

[0094] In some embodiments, the hand presence sensor 490 includes a laser emitter 492 and a light receiver 494. In some embodiments, the laser emitter 492 and the light receiver 494 are disposed in the front portion of the delivery area 400 such that the consumer's hand is detected if it is within the delivery area 400 at all. FIG. 21 shows the laser emitter 492 disposed on top of the light receiver 494, but in some embodiments, the laser emitter 492 and the light receiver 494 may be in opposite positions (i.e., the laser emitter 492 is below the light receiver 494). In some embodiments, the hand presence sensor 490 includes two opposing mirrors 496, 498 on each side of the delivery area 400. In some embodiments, the laser emitter 492 transmits a light beam 495, which is reflected back and forth between the mirrors 496, 498 until the light receiver 494 receives the light beam 495. When the consumer's hand enters the delivery area 400, the hand blocks the light beam 495, so that the light beam 495 does not reach the light receiver 494, thus enabling the hand presence sensor 490 to determine when the consumer's hand is within the delivery area 400. In some embodiments, the laser emitter 492, the light receiver 494, and the mirrors 496, 498 are positioned and angled to ensure that the hand is detected at any point along the entrance to the delivery area 400.

[0095] In some embodiments, the vending machine 10 includes a front door 30, as shown, for example, in FIG. 22. In some embodiments, the door 30 provides access to the storage space 20 and the electrical system of the vending machine when open. In some embodiments, the door 30 can be opened to reload the shelves 300 with the vending products 12, to adjust the shelves 300, or for other maintenance or repair of the vending machine 10. In some embodiments, the door 30 includes a hinge door. In some embodiments, the door 30 includes the front panel 16. In some embodiments, the door 30 includes a plastic cover 19. In some embodiments, the plastic cover 19 houses the user interface 18. In some embodiments, the door 30 is modular, and thus allows the same door 30 to be used in vending machines including different user interfaces 18 (e.g., keypad vs. touch screen).

[0096] In some embodiments, the door 30 includes rollers 32, as shown, for example, in FIGS. 23 and 24. In some embodiments, the rollers 32 are disposed on the inner frame of the door 30. In some examples, the rollers 32 are disposed at the bottom portion of the door 30. In some embodiments, the rollers 32 can be fixedly attached to the door 30. In some embodiments, the rollers 32 rest on brackets 34 disposed on the bottom portion of the external body 14 when the door 30 is closed, as shown in FIG. 24. In some embodiments, this configuration can help align the door 30 to achieve an accurate closed position and proper sealing each time the door 30 is closed.

[0097] In some embodiments, as shown in FIG. 25, the vending machine 10 includes an independent cooling unit 500. In some embodiments, the cooling unit 500 includes a high-temperature side 510 and a low-temperature side 520. In some embodiments, the high-temperature side 510 and the low-temperature side 520 are sealed to prevent mixing of high-temperature and low-temperature air. In some embodiments, the cooling unit 500 includes a heat-insulating wall 515 for separating the high-temperature side 510 and the low-temperature side 520.

[0098] In some embodiments, the high-temperature side 510 includes a condenser 512, a compressor 514, and a fan 516. In some embodiments, air enters the high-temperature side 510 through the air inlet 502 and exits the high-temperature side 510 through the exhaust port 504. In some embodiments, the low-temperature side 520 includes an evaporator 522 and a fan 524. In some embodiments, the low-temperature air 506 flows from the low-temperature side 520 into the storage space 20 to cool the vended product 12. In some embodiments, the high-temperature air 508 returns from the storage space 20 to the low-temperature side 520.

[0099] In some embodiments, as shown in FIG. 26, the vending machine 10 includes a cover panel 530 disposed on the cooling unit 500. In some embodiments, the cover panel 530 forms a duct that is attached to the vending machine 10 to carry the low-temperature air 506 into the storage space 20 and to carry the high-temperature air 508 back from the storage space 20 into the cooling unit 500.

[0100] In some embodiments, since the cooling unit 500 is independent, the cooling unit 500 can be easily removed and inserted for maintenance, repair, or replacement. In some embodiments, the cooling unit 500 operates to maintain the vended product 12 at an appropriate temperature.
