Description

Technical Field

[0001] This application relates to a supply rack, and more particularly to a supply rack, a vending machine, and a vending system. Background Technology

[0002] With the continuous maturation of artificial intelligence, the Internet of Things, big data, and robotics, traditional retail and service formats have undergone significant changes. Automated dispensing machines have greatly improved operational efficiency and customer experience. Typically, automated dispensing machines use vibration to drop goods from shelves, but the fixed vibration frequency can cause different goods to fail to drop in certain situations, leading to inventory buildup and preventing the shelves from dispensing goods properly. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a supply shelf, an automatic vending machine and an automatic vending system. The supply shelf of this application can change the vibration frequency transmitted to the shelf by the first drive device by the rotation of the eccentric wheel.

[0004] This application is achieved through the following technical solution.

[0005] The first aspect of this application provides a supply rack, one or more shelves for placing goods; and a vibration mechanism including a support body and a drive mechanism mounted on the support body. The support body is connected to the shelf and is used to transmit vibrations from the drive mechanism to the shelf. The drive mechanism includes a first drive device and an eccentric wheel assembly. The eccentric wheel assembly is connected to the output shaft of the first drive device and is rotatable with the output shaft. The eccentric wheel assembly includes at least one first eccentric wheel and at least one second eccentric wheel. The first eccentric wheel and the second eccentric wheel are rotatable relative to each other, and the center of rotation of the first eccentric wheel and the second eccentric wheel is offset relative to the axis of the output shaft.

[0006] In this application, since the first eccentric wheel and the second eccentric wheel can rotate relative to each other, and the centers of rotation of the first eccentric wheel and the second eccentric wheel are offset relative to the axis of the output shaft, the vibration frequency transmitted by the first drive device to the shelf can be changed by forming different shapes through the relative rotation of the first eccentric wheel and the second eccentric wheel. Therefore, the situation of goods piling up during the shipping process can be addressed by changing the vibration frequency.

[0007] In some embodiments, the first eccentric wheel is fixedly connected to the output shaft, and the second eccentric wheel is rotatably connected to the output shaft. The drive mechanism further includes a second drive device configured to drive the second eccentric wheel to rotate relative to the first eccentric wheel and maintain a relative position with the first eccentric wheel.

[0008] The second drive device can drive the second eccentric wheel to rotate relative to the first eccentric wheel. Once the second eccentric wheel rotates to the vibration frequency required by the first drive device, the second drive device drives the second eccentric wheel to maintain its relative position with the first eccentric wheel.

[0009] In some embodiments, the first eccentric wheel and the second eccentric wheel are arranged along the axial direction of the output shaft.

[0010] In some embodiments, the supply rack includes a control element for controlling at least one of a first drive unit and a second drive unit.

[0011] The control element can change the start and stop of the first drive device and / or the second drive device according to the settings, and the vibration frequency of the first drive device can be adjusted through the control element.

[0012] In some embodiments, the bracket body includes a connecting portion disposed on the shelf and a mounting portion for mounting a drive mechanism; the connecting portion includes a first connecting portion and a second connecting portion extending in a direction away from the mounting portion, the first connecting portion being disposed on a first surface of the shelf, the second connecting portion being disposed on a second surface of the shelf, and the first surface and the second surface being disposed opposite to each other.

[0013] The first connecting part and the second connecting part are respectively located on both sides of the shelf, and the shelf is clamped in the connecting part. This allows the vibration mechanism to be set in the shelf more stably, and also allows the vibration of the vibration mechanism to be transmitted to the shelf better.

[0014] In some embodiments, the support body includes a first limiting structure formed in the first connecting portion, and the shelf includes a second limiting structure, with the first limiting structure cooperating with the second limiting structure.

[0015] The first limiting structure works in conjunction with the second limiting structure to stably fix the main body of the bracket to the shelf.

[0016] In some embodiments, the shelf includes a plurality of dividers, a second limiting structure is formed as a limiting groove, and the dividers are disposed in the second limiting structure to form a channel for placing goods; the first limiting structure is formed as a limiting protrusion, and the limiting protrusion is embedded in the limiting groove.

[0017] By using a second limiting structure that can form a cargo channel with the divider to fit into the first limiting structure to form a limiting position, the need for setting up a separate second limiting structure to cooperate with the first limiting structure can be eliminated. This makes full use of the structure of the shelf itself, saves costs, and helps to achieve a compact structure.

[0018] In some embodiments, the vibration mechanism includes an auxiliary support, a first end of which is connected to the end of a second connecting portion, and the auxiliary support extends from a second surface to a first surface, with a second end of the auxiliary support disposed on the first surface.

[0019] The auxiliary support works in conjunction with the main support body to more stably fix the vibration mechanism so that the vibration mechanism can transmit vibration to the shelf.

[0020] In some embodiments, the supply rack includes a monitoring element that is signal-connected to a control element. The monitoring element is used to monitor the movement of goods and transmit monitoring signals about the movement of goods to the control element. The control element is configured to control a drive mechanism to drive based on the monitoring signals.

[0021] The control element controls the drive mechanism to drive based on the monitoring signal, and can adjust the vibration frequency of the first drive mechanism according to the specific usage conditions monitored.

[0022] In some embodiments, the shelf includes a first side and a second side, which are vertically aligned, with the first side being higher than the second side. A vibration mechanism is disposed on the first side, which causes the shelf to vibrate so that goods fall from the second side.

[0023] The first side is higher than the second side, making it easier for goods to fall off.

[0024] A second aspect of this application provides a vending machine comprising: a cabinet including a dispensing section; and a supply shelf as described in any of the first aspects, wherein goods falling from the shelf fall into the dispensing section.

[0025] Because the first and second eccentric wheels can rotate relative to each other on the shelf, and their centers of rotation are offset relative to the axis of the output shaft, the relative rotation of the first and second eccentric wheels forms different shapes, thus changing the vibration frequency transmitted from the first drive device to the shelf. Therefore, the vending machine can respond to the accumulation of goods during the dispensing process by changing the vibration frequency.

[0026] A third aspect of this application provides an automated vending system, comprising: a supply shelf sorting section as described in any of the first aspects; goods falling from the shelf being transferred to the sorting section; and a dispensing section, wherein goods sorted by the sorting section are transferred to the dispensing section.

[0027] Because the first and second eccentric wheels can rotate relative to each other on the shelf, and their centers of rotation are offset relative to the axis of the output shaft, the relative rotation of the first and second eccentric wheels forms different shapes, thus changing the vibration frequency transmitted from the first drive device to the shelf. Therefore, the automatic vending system can respond to the accumulation of goods during the dispensing process by changing the vibration frequency. Attached Figure Description

[0043] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0044] To solve the above-mentioned technical problems, this application provides a supply shelf, an automatic vending machine and an automatic vending system. The supply shelf of this application can change the vibration frequency transmitted to the shelf by the first drive device by the rotation of the eccentric wheel.

[0045] This application is achieved through the following technical solution.

[0046] With the continuous maturation of artificial intelligence, the Internet of Things, big data, and robotics, traditional retail and service formats have undergone significant changes. Automated dispensing machines have greatly improved operational efficiency and customer experience. Typically, automated dispensing machines use vibration to drop goods from shelves, but the fixed vibration frequency can cause different goods to fail to drop in certain situations, leading to inventory buildup and preventing the shelves from dispensing goods properly.

[0047] To solve the above-mentioned technical problems, this application provides a supply shelf, an automatic vending machine and an automatic vending system. The supply shelf of this application can change the vibration frequency transmitted to the shelf by the first drive device by the rotation of the eccentric wheel.

[0048] This application provides a supply rack, including one or more shelves for placing goods; and a vibration mechanism, including a support body and a drive mechanism mounted on the support body. The support body is connected to the shelves for transmitting vibrations from the drive mechanism to the shelves. The drive mechanism includes a first drive device and an eccentric wheel assembly. The eccentric wheel assembly is connected to the output shaft of the first drive device and can rotate with the output shaft. The eccentric wheel assembly includes at least one first eccentric wheel and at least one second eccentric wheel. The first eccentric wheel and the second eccentric wheel can rotate relative to each other, and the center of rotation of the first eccentric wheel and the second eccentric wheel is offset relative to the axis of the output shaft.

[0049] In this application, since the first eccentric wheel and the second eccentric wheel can rotate relative to each other, and the centers of rotation of the first eccentric wheel and the second eccentric wheel are offset relative to the axis of the output shaft, the vibration frequency transmitted by the first drive device to the shelf can be changed by forming different shapes through the relative rotation of the first eccentric wheel and the second eccentric wheel. Therefore, the situation of goods piling up during the shipping process can be addressed by changing the vibration frequency.

[0051] like Figures 1 to 12As shown, the supply rack 1 of this application may include one or more shelves 20 and a vibration mechanism 10. The shelves 20 can be used to place goods, and the vibration mechanism 10 includes a support body 110 and a drive mechanism mounted on the support body 110. The support body 110 is connected to the shelves 20 and is used to transmit vibrations from the drive mechanism to the shelves 20.

[0052] In some embodiments, the supply rack 1 may include multi-layer shelves 20, which are arranged along the vertical direction X. The multi-layer shelves 20 may be parallel to each other or arranged at other angles, which is not limited in this application. The vertical direction X may be parallel to the direction of gravity, but this application is not limited to this. In some embodiments, if the supply rack is located in a vacuum environment, the vertical direction X may also be perpendicular to the mounting plane.

[0053] like Figure 1 and Figure 2 As shown, the shelf 20 includes a first side 21 and a second side 22. Along the vertical direction X, the first side 21 can be higher than the second side 22. A vibration mechanism 10 is disposed on the first side 21. The vibration mechanism 10 drives the shelf 20 to vibrate, causing goods to fall from the second side 22. Because the first side 21 is higher than the second side 22 along the vertical direction X, goods can move from the first side 21 to the second side 22 based on gravity. Combined with the vibration of the vibration mechanism 10, this further facilitates the falling of goods.

[0054] In this application, the main body 110 of the support can be fixed to the working shelf by bolts. Vibration is transmitted to the entire layer of the cargo channel. Through the deflection deformation of the material of the cargo channel, the entire cargo channel has vibration transmitted in the direction of supply, thereby driving the goods (e.g., medicines, food and other commodities) on the cargo channel to move in the direction of supply, causing the material on the entire layer of the cargo channel to slide down.

[0055] In some embodiments, the vibration mechanism 10 vibrates and, based on the connection between the support body 110 and the shelf 20, can transmit the vibration to the shelf 20. Under the action of vibration, the goods 3 can move along such a path. Figure 4 and Figure 5 Move in the direction indicated by the straight arrow in the middle until it falls from the second side 22.

[0056] like Figures 1 to 6 As shown, the shelf 20 may include a divider 23, and the first surface 201 of the shelf 20 may have a second limiting structure 24. The divider 23 may be installed on the second limiting structure 24 to form a cargo channel, and the goods 3 may move along the cargo channel.

[0057] The bracket body 110 may include a mounting part 11 and a connecting part 12. The mounting part 11 can be used to mount a drive mechanism, and the connecting part 12 can be used to connect with the shelf 20. The mounting part 11 may be formed with a mounting groove. The bracket body 110 may also include a protective cover 14. The protective cover 14 can be detachably disposed in the mounting groove. The drive mechanism is disposed in the mounting groove, and the protective cover 14 is fastened to the mounting groove to protect the drive mechanism.

[0058] like Figures 8 to 10 As shown, the connecting part 12 may include a first connecting part 121 and a second connecting part 122 extending in a direction away from the mounting part 11. The first connecting part 121 is disposed on the first surface 201 of the shelf 20, and the second connecting part 122 is disposed on the second surface 202 of the shelf 20. The first surface 201 and the second surface 202 may be disposed opposite to each other along the vertical direction X.

[0059] The first connecting part 121 and the second connecting part 122 are respectively provided on both sides of the shelf 20, and the shelf 20 is clamped in the connecting part, so that the vibration mechanism can be set in the shelf more stably, and the vibration of the vibration mechanism can be better transmitted to the shelf.

[0060] In some embodiments, such as Figures 7 to 10 As shown, the support body 110 may include a first limiting structure 123 formed at the first connecting portion 121, and the shelf 20 may include a second limiting structure 24, with the first limiting structure 123 cooperating with the second limiting structure 24. For example, the first limiting structure 123 may be located at the end of the first connecting portion 121, but this application is not limited to this, as long as it can cooperate with the second limiting structure 24. By cooperating with the first limiting structure 123 and the second limiting structure 24, the support body 110 is stably fixed to the shelf 20, and positioning and installation are convenient.

[0061] It should be noted that the second limiting structure 24, which cooperates with the first limiting structure 123, can be the second limiting structure that cooperates with the divider 23 to form a cargo channel, as described above. By using the second limiting structure that can form a cargo channel with the divider to fit into the first limiting structure to form a limiting position, it is possible to save the need for a separate second limiting structure to cooperate with the first limiting structure, making full use of the structure of the shelf itself, saving costs and facilitating structural compactness. However, this application is not limited to this. In some embodiments, the second limiting structure 24 can be separately and independently provided on the shelf 20.

[0062] In some embodiments, the second limiting structure 24 is formed as a limiting groove, the separator 23 is disposed on the second limiting structure to form a cargo channel for placing goods, and the first limiting structure 123 is formed as a limiting protrusion, which is embedded in the limiting groove to limit the first connecting part 121 and the shelf 20 to each other.

[0063] In some embodiments, such as Figures 7 to 10 As shown, the vibration mechanism 10 also includes an auxiliary support 13. The first end of the auxiliary support 13 is connected to the second connecting part 122, and the auxiliary support 13 can extend from the second surface 202 to the first surface 201. The second end of the auxiliary support 13 is disposed on the first surface 201 of the shelf 20.

[0064] like Figures 7 to 10 As shown, the auxiliary support 13 can generally form a U-shaped structure, that is, the auxiliary support 13 has a groove, and part of the shelf 20 can be located in the groove. The auxiliary support 13 can extend from the second side 202 of the shelf 20 to the first side 201, so that it can be connected to the support body 110 and the shelf 20 respectively to form a stable fixing structure.

[0065] In some embodiments, the bracket body 110 and the auxiliary bracket 13 can be fixedly connected by bolts, and the two bolt holes on the upper part of the auxiliary bracket 13 can be fixedly connected to the inside of the shelf by screws. The groove inside the auxiliary bracket 13 can fit and lock into the inner wall of the shelf.

[0066] The auxiliary support 13 works in conjunction with the support body 110 to more stably fix the vibration mechanism so that the vibration mechanism 10 can transmit vibration to the shelf 20.

[0067] like Figure 11 and Figure 12 As shown, the drive mechanism may include a first drive device 100 and an eccentric wheel assembly. The eccentric wheel assembly is connected to the output shaft 111 of the first drive device 100 and is rotatable with the output shaft 111. The eccentric wheel assembly may include at least one first eccentric wheel 31 and at least one second eccentric wheel 32. The first eccentric wheel 31 and the second eccentric wheel 32 are rotatable relative to each other, and the centers of gravity of the first eccentric wheel 31 and the second eccentric wheel 32 are offset relative to the axis of the output shaft 111. When the first eccentric wheel 31 rotates with the output shaft 111, the center of gravity of the first eccentric wheel 31 does not coincide with the axis of the output shaft 111. When the second eccentric wheel 32 rotates with the output shaft 111, the center of gravity of the second eccentric wheel 32 does not coincide with the axis of the output shaft 111.

[0068] In this application, the rotational centers of the first eccentric wheel 31 and the second eccentric wheel 32 are offset relative to the axis of the output shaft 111, so that the first drive device 100 is formed as an eccentric drive device.

[0069] In this application, the first eccentric wheel 31 and the second eccentric wheel 32 are capable of rotating relative to each other, allowing them to form different shapes. For example... Figure 12As shown, the first eccentric wheel 31 and the second eccentric wheel 32 can form any of the shapes A, B, C, and D. Different shapes will result in different vibration frequencies output by the first drive device 100. For example, as the angle between the first eccentric wheel 31 and the second eccentric wheel 32 increases, the degree of change in vibration frequency also increases. Specifically, Figure 12 In shape A, the angle between the first eccentric wheel 31 and the second eccentric wheel 32 is smaller than the angle between the first eccentric wheel 31 and the second eccentric wheel 32 in shape D. In this case, the shape shown in shape A causes a smaller change in the vibration frequency of the first drive device 100 than the shape shown in shape D.

[0070] In this application, there may be multiple first eccentric wheels 31 and multiple second eccentric wheels 32. The multiple first eccentric wheels 31 and multiple second eccentric wheels 32 may be arranged alternately or sequentially; this application does not impose specific limitations on this arrangement.

[0071] In some embodiments, the first eccentric wheel 31 is fixedly connected to the output shaft 111, and the second eccentric wheel 32 is rotatably connected to the output shaft 111. The drive mechanism may also include a second drive device, which may be configured to drive the second eccentric wheel 32 to rotate relative to the first eccentric wheel 31 and maintain a relative position with the first eccentric wheel.

[0072] In this application, the second driving device can be disposed at the location of the first driving device 100. The second driving device can be disposed at the location of the first eccentric wheel 31. The second driving device can be disposed between the first eccentric wheel 31 and the second eccentric wheel 32. This application does not make specific limitations, as long as it can drive the second eccentric wheel 32 to rotate relative to the first eccentric wheel 31.

[0073] In this application, the first driving device 100 can be an electric motor. The second driving device can also be an electric motor, for example, a micro motor.

[0074] The first drive device 100 is connected to the first eccentric wheel 31 and the second eccentric wheel 32 via the output shaft 111. The first eccentric wheel 31 and the output shaft 111 are fixedly connected. A micro motor (second drive device) is connected to the second eccentric wheel 32, allowing the second eccentric wheel 32 to rotate relative to the first eccentric wheel 31. This results in a change in shape, although the total mass of the overall eccentric wheel assembly of the first drive device 100 remains constant. This change in shape causes a change in the vibration frequency output by the first drive device 100, and the degree of change in vibration frequency increases as the angle between the second eccentric wheel 32 and the first eccentric wheel 31 increases.

[0075] In some embodiments, such as Figure 11 As shown, the first eccentric wheel 31 and the second eccentric wheel 32 can be arranged along the axial direction of the output shaft 111.

[0076] In some embodiments, the supply rack 1 may include a control element (e.g., a processor, a control circuit) for controlling at least one of a first drive device and a second drive device. The control element may be signal-connected to the first drive device and the second drive device respectively; for example, the control element may be connected to the first drive device and the second drive device via electrical connection, Bluetooth connection, WiFi connection, or other means.

[0077] The control element can change the start and stop of the first drive device and / or the second drive device according to the settings, and the vibration frequency of the first drive device can be adjusted through the control element.

[0078] In some embodiments, the supply rack includes a monitoring element that is signal-connected to a control element. The monitoring element is used to monitor the movement of goods and transmit monitoring signals about the movement of goods to the control element. The control element is configured to control a drive mechanism to drive based on the monitoring signals.

[0079] The control element controls the drive mechanism to drive according to the monitoring signal, and can adjust the vibration frequency of the first drive device according to the specific usage conditions monitored.

[0080] In some embodiments, the control element can determine the stacking status of goods on the shelf based on the monitoring signal transmitted by the monitoring element, thereby determining the target value for changing the vibration frequency of the first drive device. Based on the target value, the control element further controls the second drive device to drive the second eccentric wheel to rotate to form a target angle with the first eccentric wheel and controls the second eccentric wheel to maintain the angle between the second eccentric wheel and the first eccentric wheel, thereby changing the vibration frequency of the first drive device to the target value, causing the goods stacked on the shelf to fall off.

[0081] In this application, the second drive device can drive the second eccentric wheel to rotate relative to the first eccentric wheel. Once the second eccentric wheel rotates to a vibration frequency that enables the first drive device to achieve the desired vibration frequency, the second drive device drives the second eccentric wheel to maintain its relative position with the first eccentric wheel.

[0082] Based on the same or similar concept, this application may also provide an automatic vending machine, including: a cabinet, the cabinet including a dispensing section; and a supply shelf as in any of the foregoing embodiments, wherein goods falling from the shelf fall into the dispensing section.

[0083] The vending machine of this application can be a vending machine for selling medicines. Because the shelf can rotate relative to the first eccentric wheel and the second eccentric wheel, and the centers of rotation of the first and second eccentric wheels are offset relative to the axis of the output shaft, the relative rotation of the first and second eccentric wheels forms different shapes, thus changing the vibration frequency transmitted from the first drive device to the shelf. Therefore, the vending machine can respond to the accumulation of goods during the dispensing process by changing the vibration frequency.

[0084] Based on the same or similar concept, this application also provides an automated vending system, including: a supply shelf sorting unit as in any of the foregoing embodiments; goods falling from the shelf and being transferred to the sorting unit; and a dispensing unit, where goods sorted by the sorting unit are transferred to the dispensing unit.

[0085] The vending machine of this application can be an automated vending system for selling medicines, such as an automated pharmacy. Based on the feeding requirements of the automated pharmacy shelf, the stable falling of goods can be achieved by controlling the adjustable vibration frequency of the vibrating motor. Since the feeding shelf can rotate relative to a first eccentric wheel and a second eccentric wheel, and the centers of rotation of the first and second eccentric wheels are offset relative to the axis of the output shaft, the relative rotation of the first and second eccentric wheels forms different shapes, thus changing the vibration frequency transmitted from the first drive device to the shelf. Therefore, the automated vending system can cope with the accumulation of goods during the dispensing process by changing the vibration frequency.
