Description

Technical Field

[0001] The present invention relates to the field of smart retail technology, and in particular to a filling and weighing method for smart retail liquid beverages. Background Art

[0002] Automatic milk vending machines, with their advantages of high technology, new sales methods, fashion, convenience and 24-hour service, are deployed in residential communities and school dormitories to meet everyone's needs to a large extent.

[0003] However, in the existing technology, the weighing sensor of the automatic milk vending machine is easily affected by temperature and produces errors. It cannot guarantee accurate weighing, let alone ensure that the amount of each portion of fresh milk is consistent, thus bringing a bad shopping experience to consumers.

[0004] Chinese patent publication number CN 113790791B provides a method for calibrating the gravity sensor of a gravity vending machine. The method first extracts the weight value to be calibrated from the full-scale weighing weight, as well as the temperature value within the full-scale temperature range, to establish a two-dimensional data structure. Furthermore, since the gravity vending machine has more than one weighing sensor, each weighing sensor is calibrated, adding another dimension to the calibrated two-dimensional plane, creating a three-dimensional calibration space. When the gravity vending machine is completed and ready for shipment, the entire machine is calibrated, generating a calibration data table that is stored in memory. During operation, the calibration parameter table is retrieved to calculate the current weight. This allows accurate weight calculations to be made using the two-dimensional table parameters of the gravity sensor and temperature, minimizing the influence of the measurement circuit and temperature.

[0005] However, this calibration method only improves the weighing sensor. It still cannot guarantee accurate weighing for milk vending machines or liquid vending machines that need to be weighed. In particular, when multiple beverages need to be sold in the same liquid vending machine, there are higher requirements for weighing. Therefore, there is a need for a weighing method suitable for selling different liquid beverages. Summary of the Invention

[0006] In response to the above-mentioned problems, the present invention aims to provide a filling and weighing method for intelligent retail liquid beverages, which can improve weighing accuracy, ensure accurate measurement and control of fresh milk quantity, and improve consumers' milk purchasing experience.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: The present invention provides a filling and weighing method for intelligent retail liquid beverages, the method comprising the following steps: S1, calibrate the weighing sensor; S2.

[0009] Furthermore, the step S2 includes the following specific steps: S21, respectively start the forward rotation command of the delivery pump of each beverage, or manually make the delivery pump rotate forward; S22, respectively start the delivery pump reversal command for each beverage, or manually reverse the delivery pump; S23, assigning the difference between the set milking quantity and the deceleration correction quantity to the deceleration weight; S24. When the actual weighing value is less than or equal to the deceleration weight, the set speed of the delivery pump is assigned to the forward speed of the delivery pump; when the actual weighing value is greater than the deceleration weight, the deceleration speed of the delivery pump is assigned to the forward speed of the delivery pump.

[0010] Furthermore, the step S3 includes the following specific steps: S31, activating the control module of the delivery pump of each beverage; S32, the delivery pump of each beverage is running; S33. The delivery pump of each beverage stops running.

[0011] Furthermore, the step S32 includes the following specific steps: S321 delivery pump runs forward; S322 delivery pump runs in reverse.

[0012] Furthermore, the running speed of the delivery pump in step S321 includes assigning the set speed of the delivery pump to the forward speed of the delivery pump and assigning the deceleration speed of the delivery pump to the forward speed of the delivery pump.

[0013] Furthermore, the step S33 includes the following specific steps: S331 delivery pump stops running in forward direction; S332 The delivery pump reverses and stops running.

[0014] Furthermore, in step S33 , the set speed of the delivery pump is assigned to the forward rotation speed of the delivery pump.

DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0018] The inventors have found that the existing smart retail filling and weighing methods cannot guarantee accurate weighing, especially when multiple beverages need to be sold at the same vending machine, which places higher requirements on weighing.

[0019] Based on the above findings, the present application proposes a filling and weighing method for intelligent retail liquid beverages, which is a contactless intelligent filling method for liquid beverages. The weighing sensor can transmit real-time weight, and the delivery pump can dynamically weigh, which improves the weighing accuracy and ensures the precise measurement and control of each liquid quantity. The entire filling process is simple to operate, which improves the automation level and filling efficiency of the liquid beverage vending machine.

[0020] The present invention provides a filling and weighing method for intelligent retail liquid beverages, please refer to Figure 1 , the method comprises the following steps: S1, calibrate the weighing sensor; S2. Calibrate the delivery pump for each beverage; S3, dynamic weighing.

[0021] See also Figure 2 , step S1, includes the following specific steps: S11, zeroing: remove the load or foreign matter on the weighing tray; S12, weight confirmation: Place standard weights on the weighing tray and enter the weight value; S13. Remove the weights after completion.

[0022] The high-precision weighing sensor ensures accurate measurement of the fresh milk quantity. The weighing sensor also has long-term stability and anti-interference capabilities to adapt to the complex operating environment of the milk vending machine.

[0023] See also Figure 3 , step S2, includes the following specific steps: S21, respectively start the forward rotation command of the delivery pump of each beverage, or manually make the delivery pump rotate forward; S22, respectively start the delivery pump reversal command for each beverage, or manually reverse the delivery pump; S23, assigning the difference between the set milking quantity and the deceleration correction quantity to the deceleration weight; S24. When the actual weighing value is less than or equal to the deceleration weight, the set speed of the delivery pump is assigned to the forward speed of the delivery pump; when the actual weighing value is greater than the deceleration weight, the deceleration speed of the delivery pump is assigned to the forward speed of the delivery pump.

[0024] See also Figure 4 , step S3, includes the following specific steps: S31, activating the control module of the delivery pump of each beverage; S32, the delivery pump of each beverage is running; S33. The delivery pump of each beverage stops running.

[0025] Step S32 includes the following specific steps: S321 delivery pump runs forward; S322 delivery pump runs in reverse.

[0026] In step S321 , the running speed of the delivery pump includes assigning the set speed of the delivery pump to the forward rotation speed of the delivery pump and assigning the deceleration speed of the delivery pump to the forward rotation speed of the delivery pump.

[0027] Step S33 includes the following specific steps: S331 delivery pump stops running in forward direction; S332 The delivery pump reverses and stops running.

[0028] In step S33 , the set speed of the delivery pump is assigned to the forward rotation speed of the delivery pump.

[0029] This weight measurement method ensures that the amount of each liquid beverage, including fresh milk, is consistent, meeting consumers' precise demand for beverage amounts. At the same time, the equipment operates with low noise, making it suitable for 24-hour self-service in communities, campuses and other scenarios.

[0030] The delivery pump can automatically adjust the liquid output according to the preset beverage quantity standard to ensure the consistency of the quantity of each beverage; it realizes the dynamic weighing function, that is, the beverage weight is monitored in real time during the liquid sales process to ensure the accuracy of the quantity.

[0031] Improved weight accuracy and user experience meet the needs of different consumers; improved the automation level and operating efficiency of liquid vending machines, providing consumers with a more convenient and efficient experience in purchasing and selling liquid beverages.

[0032] The specific implementation process of the filling and weighing method for intelligent retail liquid beverages of the present invention is as follows: First, the weighing sensor is calibrated, the scale is reset, the weight is confirmed, the weight value is moved to a storage location, and a check is performed to determine whether the weight is 0. If the condition is false, a value is moved to the storage location, and the weighing result is displayed as 0. Through these steps, the weighing result is finally output.

[0033] Then, the delivery pump of each beverage is calibrated. The delivery pump of each beverage is rotated forward and then reversed, and the difference between the set amount of milk frothing and the deceleration correction amount is assigned to the deceleration weight; according to the different actual weighing values ​​of different beverages, when the actual weighing value is less than or equal to the deceleration weight, the set speed of the delivery pump is assigned to the forward speed of the delivery pump; when the actual weighing value is greater than the deceleration weight, the deceleration speed of the delivery pump is assigned to the forward speed of the delivery pump.

[0034] After calibration, the control module controls the forward and reverse rotation of the delivery pump. By judging the actual instructions and set speed, the operating parameters of the pump are adjusted to ensure that the pump can move at the expected speed and direction.

[0035] During the filling process, the weighing sensor transmits data to the control system in real time. When the liquid weight approaches the set value, the delivery pump automatically adjusts its speed, slowly discharging the liquid to ensure accurate weighing. Once the liquid is discharged, the delivery pump quickly reverses to prevent dripping and ensure that the liquid returns to the constant temperature chamber without damage to the liquid head.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the scope of protection of the present invention.
