Description

Technical Field

[0001] The utility model relates to the technical field of container falling, in particular to a cup dropping device and an automatic coffee vending machine. Background Technique

[0002] With the improvement of people's living standards and the continuous improvement of the requirements for the quality of life, more and more people will buy some beverages to meet their own needs, and coffee is one of them.

[0003] Coffee refers to a beverage made from roasted and ground coffee beans. Together with cocoa and tea, it is one of the main beverages popular in the world. In order to meet the needs of a large number of white-collar workers in office buildings to drink coffee, coffee vending machines will be set up in office buildings. White-collar workers can quickly get a cup of coffee they want just by paying. In general, coffee capsules are brewed in cups in the coffee vending machine. The cups are stored in the coffee machine. After payment, the cups will automatically fall from the cup dropping device in the coffee machine. Although the existing cup dropping devices can also realize the automatic falling of cups, they can only report whether there is a lack of cups and cannot automatically replace the cups with spare cups when there is a lack of cups. Manual replacement is still required. If the spare cups cannot be replaced in time by personnel, the brewed coffee cannot be obtained, which affects the user experience. Content of the Utility Model

[0004] In order to achieve the above object, the utility model provides the following technical solutions:

[0005] A cup dropping device includes a moving component, a dropping component, a first goods channel and a second goods channel. The upper ends of the first goods channel and the second goods channel are connected by a first fixing member. The outside of the lower ends of the first goods channel and the second goods channel is surrounded by a fixed clamping plate and a movable clamping plate. Both ends of the moving component are respectively connected to the movable clamping plate and the fixed clamping plate, and an upper cover for protecting the moving component is installed between the moving component and the movable clamping plate. The dropping component is located below the moving component, and a lower cover for protecting the dropping component is installed at the bottom end of the dropping component. The dropping component includes a dropping motor, a laser emitter pair and an annular gear. The output end of the dropping motor is installed with a driving wheel, and the driving wheel meshes with the outer ring of the annular gear. The inner ring of the annular gear meshes with a plurality of clamping wheels, and the clamping wheels are connected to the movable clamping plate. The laser emitter pair is installed on the middle cover, and the middle cover is located between the dropping component and the moving component. In the initial state, both the first goods channel and the second goods channel are filled with cups. When cup dropping is required, the dropping motor receives an instruction and operates. The dropping motor drives the driving wheel to rotate, and the driving wheel drives the clamping wheels to rotate through the annular gear. The clamping wheels drive the movable clamping plate to move, so that the cups drop from the first goods channel. When the laser emitter pair can achieve beam alignment, it indicates that there is no cup dropping at this time. At this time, it can be explained that the first goods channel is in a state of lacking cups, and it can be automatically reported to the control chip. The control chip sends a signal to the moving component, and the moving component drives the second goods channel to move. When the second goods channel moves to the position of the current first goods channel, the moving component stops operating, and cup dropping can be continued. This device can not only be used to store coffee cups, but also be used to store cup lids, etc., and has a wide range of applications.

The movable clamping plate and the fixed clamping plate can be fixed together, so as to tightly surround the first goods channel and the second goods channel, and the containers will not leak out from the first goods channel and the second goods channel.

[0008] As a further solution of the present utility model: The moving assembly includes a moving motor and two shafts. A slider is slidably mounted on each shaft. The output end of the moving motor is equipped with a rotating wheel, which meshes with a toothed rail. The toothed rail is fixed to one slider, and this slider is connected to the second goods lane. Limit switches are provided on both sides in the length direction of the toothed rail. When it is necessary to drive the second goods lane to move, the moving motor receives the signal sent by the control chip and starts to work. The moving motor drives the rotating wheel to rotate. The rotating wheel drives the slider to move through the toothed rail, and the slider drives the second goods lane to move. When the rotating wheel touches the limit switch, it indicates that the second goods lane has moved to the position of the previous first goods lane. At this time, the limit switch sends a signal to the control chip, and the control chip sends a signal to the moving motor, and the moving motor stops working.

[0009] As a further solution of the present utility model: Both the falling motor and the moving motor adopt servo motors, which realize the closed-loop control of position, speed and torque, overcome the problem of step loss of the stepping motor, have good use stability and high use accuracy, and ensure that the card wheel and the slider can accurately stay at the specified position.

[0010] As a further solution of the present utility model: The upper cover, the middle cover and the lower cover are all made of PVC material and injection molding process. The raw materials are easy to obtain, convenient to process, and have good protection effect.
