Description

Technical Field

[0001] This utility model relates to the technical field of lifting and transmission devices for automatic bowl-type food vending machines, and in particular to a multi-station lifting, rotating, and telescopic transmission machine for bowl-type food in automatic vending machines. Background Technology

[0002] The automatic bowl-shaped food vending machine is a new type of equipment combining intelligent technology, automated processing, and unmanned retail, aiming to provide users with convenient, efficient, and diversified catering services. Existing technology, Chinese utility model disclosure number CN218996092U, discloses an integrated automatic bowl-shaped food production and online vending machine, characterized by including a frame device, a refrigerated cabinet device, a tableware storage and conveying device, a vending cabinet device, a soup and condiment storage tank and a swing arm condiment positioning and adding device, a retractable and lifting vending platform device, and a meal selection, payment, and power supply control device. This utility model addresses the shortcomings of existing food preparation processes that are relatively complex and labor-intensive by providing an integrated automatic bowl-shaped food production and online vending machine that replaces manual operation, consolidating all scattered processes into one machine to complete the production and sale of bowl-shaped foods.

[0003] The soup and condiment storage and swing arm positioning and adding device, and the telescopic lifting platform device in the above-mentioned automatic vending machine have complex structures and cannot move in multiple directions or at multiple points. The existing robotic arm can replace the work needs, but the related components of the robotic arm include servo motors, which are high-cost components. In order to simplify the structure and reduce costs, we have designed a multi-station lifting, rotating, and telescopic transmission machine for bowl-shaped food in automatic vending machines. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an automatic vending machine for multi-station lifting, rotating, and telescopic conveying of bowl-shaped food. It employs a drive structure consisting of an electric push-pull rod, chain, sprocket, and tension spring. The extension and retraction of the electric push-pull rod, combined with the tension spring, controls the chain to rotate the sprocket, which in turn drives the hollow main shaft to rotate the telescopic bowl tray component. Compared to using a servo motor drive, this significantly reduces manufacturing costs, thereby saving on the production cost of the automatic vending machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An automatic vending machine for bowl-shaped food, featuring multi-station lifting, rotating, and telescopic conveying, is characterized by comprising a lifting component, a rotating drive component, and a telescopic bowl-supporting slot component. The lifting component is connected to the rotating drive component, and the telescopic bowl-supporting slot component is connected above the rotating drive component. The rotating drive component consists of a support frame, a tension spring, a chain, a sprocket, an electric push-pull rod, a hollow main shaft, and a rotational position detection component. The support frame is connected to the lifting component, and the electric push-pull rod is mounted on the support frame. The telescopic end of the electric push-pull rod is connected to one end of the chain, and the other end of the chain is connected to the tension spring. The other end of the tension spring is fixed to the support frame. Some links of the chain are connected to the tooth grooves of the sprocket. The sprocket is mounted on the hollow main shaft, and the upper end of the hollow main shaft is connected to the telescopic bowl-supporting slot component. A rotational position detection component is located below the telescopic bowl-supporting slot component and is mounted on the support frame.

[0007] The support frame consists of a mechanical arm, an upper plate of the mechanical arm, and a lower plate of the mechanical arm. The mechanical arm is fixedly installed between the upper plate and the lower plate of the mechanical arm, and the mechanical arm divides the space between the upper plate and the lower plate of the mechanical arm equally, so that the electric push-pull rod and the tension spring are located in the two spaces respectively.

[0008] The upper end of the hollow spindle passes through the upper plate of the mechanical arm and extends out to connect with the telescopic cup groove component. An upper bearing is provided at the connection between the upper end of the hollow spindle and the upper plate of the mechanical arm. The lower end of the hollow spindle passes through the lower plate of the mechanical arm and extends out, and a hollow spindle conductive slip ring is installed at the extended part. A lower bearing is provided at the connection between the lower end of the hollow spindle and the lower plate of the mechanical arm.

[0009] The rotation position detection component includes a fixed plate and a magnetic switch. The fixed plate is mounted on the upper plate of the mechanical arm, and the magnetic switch is installed on the fixed plate.

[0010] The telescopic bowl-supporting groove component consists of a mechanical arm, a telescopic electric push-pull rod, a telescopic bowl-supporting groove of the mechanical arm, an electric push-pull rod for pushing the bowl, and a push-bowl plate. The mechanical arm is connected to the upper end of the hollow main shaft. A telescopic electric push-pull rod is installed on one side of the upper end of the mechanical arm. The telescopic end of the telescopic electric push-pull rod is connected to the telescopic bowl-supporting groove of the mechanical arm. An electric push-pull rod for pushing the bowl is installed inside the telescopic bowl-supporting groove of the mechanical arm. The telescopic end of the electric push-pull rod for pushing the bowl is connected to the push-bowl plate.

[0011] Furthermore, a magnet is installed at the bottom of the mechanical arm. When the hollow spindle drives the mechanical arm to rotate, the magnet moves to the magnetic switch in the rotation position detection component. The magnetic switch is a magnetic induction switch. The angle of the mechanical arm is determined by detecting the proximity of the magnet, and a signal is fed back to the control system to control the electronic components in the telescopic cup tray component.

[0012] Furthermore, the mechanical forearm telescopic bowl-holding groove contains a bowl, which is located at the front side of the bowl-pushing plate.

[0013] Furthermore, the bottom of the telescopic cup-holding groove of the mechanical arm is provided with a sliding groove that is adapted to and connected to the cup-holding groove slide rail, and the cup-holding groove slide rail is installed on the mechanical arm.

[0014] Furthermore, the lifting component is existing technology. The lifting component includes a lifting winch, a steel wire rope, a slide rail, a slider, and a lifting plate. The lifting winch is connected to the lifting plate via the steel wire rope. A slider is installed on one side of the lifting plate. The slider is slidably connected to the slide rail. The lifting winch controls the lifting and lowering movement of the lifting plate, thereby realizing the lifting and lowering of the rotation drive component and the telescopic bowl tray component, thus realizing the output of bowls to different bowl output layers in the refrigerator.

[0015] Specifically, the electronic components in the lifting component, the rotating drive component, and the telescopic tray slot component are all electrically connected to the PLC control system in the automatic vending machine to control the start-up and operation of each electronic component.

[0016] The beneficial effects of this utility model are:

[0017] This utility model designs a rotation drive component that drives the robotic arm of the telescopic bowl tray component to rotate to different work positions. It adopts a drive structure consisting of an electric push-pull rod, a chain, a sprocket, and a tension spring. Through the extension and retraction of the electric push-pull rod and the cooperation of the tension spring, the chain is controlled to drive the sprocket to rotate, which in turn drives the hollow main shaft to control the rotation of the telescopic bowl tray component. Compared with a servo motor, the rotation drive component designed in this utility model has a significantly lower manufacturing cost, thereby saving the manufacturing cost of automatic vending machines.

[0018] In this utility model, the telescopic bowl tray component is designed with a telescopic electric push-pull rod to control the axial movement of the mechanical arm holding the bowl, thereby controlling the bowl to move to the corresponding workstation for processing. In addition, the electric push-pull rod is designed to push the bowl out of the workstation at the sales window to complete the sale.

[0029] Example 1

[0030] As shown in the figure, an automatic vending machine for bowl-shaped food includes a lifting, rotating, and telescopic conveying mechanism, comprising a lifting component, a rotating drive component, and a telescopic bowl tray component. The electronic components in the lifting component, rotating drive component, and telescopic bowl tray component are electrically connected to the PLC control system in the automatic vending machine to control the start-up and operation of each electronic component.

[0031] The lifting component is existing technology. The lifting component includes a lifting winch 3, a steel wire rope 4, a slide rail 1, a slider 2, and a lifting plate 5. The lifting winch 3 is connected to the lifting plate 5 through the steel wire rope 4. The slider 2 is installed on one side of the lifting plate 5 and is slidably connected to the slide rail 3. The lifting plate 5 is connected to the mechanical arm 6 in the rotation drive component. Therefore, the lifting winch 3 controls the lifting and lowering movement of the lifting plate 5, thereby enabling the mechanical arm 6 to move up and down with the lifting plate 5 to work, thus realizing the output of bowls to different bowl output layers in the refrigerator.

[0032] The mechanical arm 6 in the rotation drive component is installed between the upper plate 7 and the lower plate 8 of the mechanical arm, and evenly divides the space between the upper plate 7 and the lower plate 8 of the mechanical arm, so that the electric push-pull rod 15 and the tension spring 14 are separated and located in two spaces respectively.

[0033] The electric push-pull rod 15 is mounted on the support frame via the electric push-pull rod shaft pin connector 16. The telescopic end of the electric push-pull rod 15 is connected to one end of the chain 13, and the other end of the chain 13 is connected to the tension spring 14. The other end of the tension spring 14 is fixed on the support frame. Some links on the chain 13 are connected to the tooth groove of the sprocket 12. The sprocket 12 is mounted on the hollow main shaft 9. The upper end of the hollow main shaft 9 passes through the upper plate 7 of the mechanical arm and extends out to connect with the mechanical arm 20 in the telescopic cup slot component. An upper bearing 10 is provided at the connection between the upper end of the hollow main shaft and the upper plate 7 of the mechanical arm. The lower end of the hollow main shaft 9 passes through the lower plate 8 of the mechanical arm and extends out, and a hollow main shaft conductive slip ring 46 is installed at the extended part. A lower bearing 11 is provided at the connection between the lower end of the hollow main shaft 9 and the lower plate 8 of the mechanical arm.

[0034] A rotation position detection component is provided between the upper plate 7 of the mechanical arm and the lower arm 20 in the rotation drive component. Multiple sets of magnetic switches 18 in the rotation position detection component are installed on the fixed plate 17 according to the detection position. The fixed plate 17 is installed on the upper plate 7 of the mechanical arm. A magnet 19 is installed at the bottom of the lower arm 20. When the hollow spindle 9 drives the lower arm 20 to rotate, the magnet 19 moves to the corresponding magnetic switch 18 in the rotation position detection component. The magnetic switch 18 is a magnetic induction switch. It determines the angle of the lower arm by detecting the proximity of the magnet and feeds back the signal to the PLC control system to control the electronic components in the telescopic cup tray component.

[0035] In the telescopic bowl-holding slot component, a telescopic electric push-pull rod 26 is mounted on one side of the upper end of the mechanical arm 20 via a telescopic electric push-pull rod pin connector 27. The telescopic end of the telescopic electric push-pull rod 26 is connected to the telescopic bowl-holding slot 24 of the mechanical arm. A push-bowl electric push-pull rod 30 is mounted inside the telescopic bowl-holding slot 24 via a push-bowl electric push-pull rod pin connector 31. The telescopic end of the push-bowl electric push-pull rod 30 is connected to the push-bowl plate 34 via a telescopic rod and a fixed connector. A bowl 25 is contained within the telescopic bowl-holding slot 24 of the mechanical arm, and the bowl 25 is located at the front of the push-bowl plate 34.

[0036] Furthermore, a sliding groove 23 is provided at the bottom of the telescopic cup-holding groove 24 of the mechanical arm, which is adapted to connect with the cup-holding groove slide rail 22. The cup-holding groove slide rail 22 is installed on the mechanical arm 20.

[0037] Example 2

[0038] When installed in an automatic vending machine, this utility model controls the lifting plate 5 to move up and down through the lifting winch 3 in the lifting component, thereby enabling the mechanical arm 6 to move up and down with the lifting plate 5 to work, thus enabling the output of bowls to different bowl output layers in the refrigerated cabinet 47.

[0039] When the mechanical arm 20 in the telescopic bowl tray component rotates to different work positions, the extension and retraction of the electric push-pull rod 15 in the rotation drive component, in conjunction with the tension spring 14, drives the chain 13 to rotate the sprocket 12, which in turn drives the hollow main shaft 9 to rotate. This allows the mechanical arm 20 to adjust its angle, enabling the bowl 25 to move between the bowl receiving station 35, the soup and condiment adding station 36, and the dispensing and selling window and bowl pushing station 38. Compared to a servo motor, the rotation drive component designed in this invention significantly reduces manufacturing costs, thereby saving on the manufacturing cost of the automatic vending machine.

[0040] The telescopic electric push-pull rod 26 in the telescopic bowl tray component controls the overall axial movement of the telescopic bowl tray 24 of the mechanical arm, and pushes the bowl 25 out of the telescopic bowl tray 24 of the mechanical arm through the push-bowl electric push-pull rod 30, thus completing the delivery of the prepared bowl-shaped food out of the preparation machine.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
