Referring to fig. 1, an embodiment of the present application provides a discharge control method, which includes the following steps.
In step S01, the initial weight of the container is obtained.
The execution subject of this step may be a PLC (Programmable Logic Controller). Paste on the container and have the two-dimensional code, the user passes through the two-dimensional code on the scanning rifle scanning container, and the scanning rifle links to each other with host computer communication, and the scanning rifle sends the two-dimensional code for the host computer, and the host computer obtains order information through this two-dimensional code of discernment. The upper computer is in communication connection with the PLC, and for example, the upper computer can be in mutual communication with the PLC through Wi-Fi (wireless fidelity). The upper computer sends the order information to the PLC, and the PLC receives the order information and then moves the container to the position below the discharge hole. PLC can grab the container to the tray of discharge gate below through the control arm on, also can be through transport mechanism, with the container transmission to the tray of discharge gate below. A load cell is disposed in the tray and detects an initial weight of the container. The weighing sensor is in communication connection with the PLC, for example, the weighing sensor is in communication with the PLC through an RS-485 protocol. The load cell transmits the initial weight to the PLC.
The containers placed on the tray may be empty, i.e. not filled with drinks. The beverage comprises a first material, a second material and a third material. The containers placed on the tray may also be filled with a third material. Thus, the initial weight of the container may be the net weight of the container or the sum of the net weight of the container and the weight of the third material. The net weight of the container is the weight of the container when it is empty of anything.
The beverage may be milk tea, the second material may be syrup, and the third material may be pulp, such as mango pulp, apple pulp, pearl, coconut, comfrey, etc. The third material may also be another material of the beverage. The first material is the other material of the drink than the second material and the third material, for example, the first material includes water, cream and milk.

The discharging sequence of the first material and the second material can be determined according to the initial weight.
The first material and the second material can be discharged simultaneously or sequentially.
And step S03, acquiring the current weight of the container in the discharging process.
When the first material and the second material are pumped into the container, the current weight of the container changes, the weighing sensor detects the current weight of the container in real time, the current weight of the container is the sum of the net weight of the container and the current weight of the beverage in the container, and the current weight of the beverage in the container is the weight of the beverage in the container at the current moment.
And step S04, controlling the first discharging speed of the first material according to the current weight.
According to the discharging control method, the initial weight of the container is detected, the discharging sequence of the first material and the second material is controlled according to the initial weight, and before the first material and the second material are discharged, when other materials are filled in the container, the discharging sequence of the first material and the second material is controlled, so that splashing caused when the materials discharged later fall into the container can be prevented; still at ejection of compact in-process, acquire the current weight of container to according to the first ejection of compact speed of current weight control first material, thereby can be according to the real-time weight of container, the ejection of compact speed of control material both can improve discharging efficiency, the degree of splashing when can rationally controlling first material again and dropping to the container, satisfy user's requirement.
Referring to fig. 2, in one embodiment, the discharge control method may further include the following steps.
Step S101, receiving order information, wherein the order information includes a first type of a first material, a weight of the first material of the first type, a second type of a second material, and a weight of each second material of the second type, the first material includes a plurality of the first types, and the second material includes a plurality of the second types.
The first material may comprise a plurality of first types, and the weight of each first type of first material may be different. The first type of the first item in the order information is one of a plurality of first types of the first item. For example, the first material may include 9 first types, and the 9 first types are first material a, first material b, first material c, first material d, first material e, first material f, first material g, first material h, and first material i, respectively. The first type of the first material in the order information is one of 9 first types, for example, the first type of the first material is a first material e, and the weight of the first material of the first type is the weight of the first material e.
The second material may comprise a plurality of second types, and the weight of each second type of second material may be different. The order information includes a plurality of second types of second materials. For example, when the second material is syrup, the second types of the second material may be syrup 1, syrup 2, syrup 3, syrup 4, syrup 5, and syrup 6, respectively, and the second types of the second material in the order information may include syrup 1, syrup 2, syrup 3, syrup 4, syrup 5, and syrup 6. The weight of each second type of second material in the order information may be: 20g of syrup 1, 0g of syrup 2, 10g of syrup 3, 5g of syrup 4, 0g of syrup 5 and 0g of syrup 6.
Step S102, analyzing the order information to generate a first control signal and a second control signal.
The upper computer can send the order information to the PLC in a form of a table. And the PLC analyzes the received table and generates a corresponding first control signal and a second control signal according to an analysis result.
Step S103, transmitting the first control signal to a corresponding first fluid pump motor and transmitting the second control signal to a corresponding second fluid pump motor, wherein the number of the first fluid pump motors is multiple, the first fluid pump motors correspond to the first type one to one, each first fluid pump motor is used for pumping a first material corresponding to the first type, the number of the second fluid pump motors is multiple, the second fluid pump motors correspond to the second type one to one, and each second fluid pump motor is used for pumping a second material corresponding to the second type.
The PLC is electrically connected with the first fluid pump motor and the second fluid pump motor respectively. The PLC transmits the first control signal to the corresponding first fluid pump motor and transmits the second control signal to the corresponding second fluid pump motor, so that the corresponding first fluid pump motor is controlled to pump out the first material and the corresponding second fluid pump motor is controlled to pump out the second material. For example, the first material includes 9 first types, the number of the first fluid pump motors is 9, and if the first type of the first material is the first material e, the PLC transmits a first control signal to the first fluid pump motor corresponding to the first material e to control the first fluid pump motor to pump out the first material e. If the second type of second material is 6 and is syrup 1, syrup 2, syrup 3, syrup 4, syrup 5 and syrup 6, respectively, the number of the second fluid pump motors is 6, if the weight of each second type of second material is: 20g of syrup 1, 0g of syrup 2, 10g of syrup 3, 5g of syrup 4, 0g of syrup 5 and 0g of syrup 6, wherein the PLC transmits second control signals to a second fluid pump motor corresponding to the syrup 1, a second fluid pump motor corresponding to the syrup 3 and a second fluid pump motor corresponding to the syrup 4 respectively, controls the second fluid pump motor corresponding to the syrup 1 to pump out the syrup 1, controls the second fluid pump motor corresponding to the syrup 3 to pump out the syrup 3 and controls the second fluid pump motor corresponding to the syrup 4 to pump out the syrup 4.
Each second fluid pump motor and each first fluid pump motor has a pump outlet. The discharge port includes pump outlets of the plurality of second fluid pump motors and pump outlets of the plurality of first fluid pump motors. The pump outlets of the second fluid pump motors and the pump outlets of the first fluid pump motors can be circularly arranged, and the container opening can be circular, so that the shape of the discharge opening can be matched with the shape of the container opening, and the total area of the discharge opening is smaller than the total area of the container opening.
The first material and the second material are discharged simultaneously, the first material and a plurality of second materials of the second type are discharged simultaneously, and each second material of the second type is discharged simultaneously.
If the second material is discharged first, when the second material is discharged, the first material is discharged again, namely, when the second materials of the second types are discharged, the first material is discharged again.
The discharging of the first material and the second material is controlled according to the types of the first material and the second material in the order information, so that the materials of the drink are mixed and discharged, the formula of the drink is enriched, and the automatic discharging can be realized.
The order information further includes a first predetermined weight, which is the sum of the net weight of the container and the weight of all the materials in the beverage. The upper computer can pre-store the first preset weight corresponding to each two-dimension code, and when the upper computer identifies the two-dimension code, the upper computer adds the first preset weight corresponding to the two-dimension code to order information.
Referring to fig. 3, in one embodiment, the step S02 of determining the discharging order of the first material and the second material according to the initial weight includes:
step S21, a fourth preset weight and a fifth preset weight are obtained, where the fourth preset weight is smaller than the fifth preset weight.
The fourth predetermined weight is the net weight of the container. The fifth predetermined weight is the sum of the net weight of the container and the predetermined weight of the third material. The order information may further include a fourth preset weight and a fifth preset weight, and the PLC may obtain the fourth preset weight and the fifth preset weight by analyzing the order information. Of course, the fourth preset weight and the fifth preset weight may also be stored in the PLC in advance, and the PLC may obtain the fourth preset weight and the fifth preset weight matched with the order information by analyzing the content of the order information.
The fourth predetermined weight may be, for example, 5 grams. The fifth preset weight may be, for example, 25 grams.
In step S22, the initial weight is compared with a fourth predetermined weight and a fifth predetermined weight, respectively.
And step S23, controlling the first material and the second material to be discharged simultaneously under the condition that the initial weight is less than or equal to the fourth preset weight.
And step S24, controlling the second material to be discharged first when the initial weight is larger than the fourth preset weight and smaller than the fifth preset weight, and controlling the first material to be discharged when the second material is discharged.
And step S25, sending out an alarm signal when the initial weight is larger than or equal to the fifth preset weight.
When the container placed below the discharge port is filled with the third material, the third material occupies a certain volume of the container, the falling distance of the material is reduced, and the material is easier to splash out of the container. When other materials are filled in the container, the second material is controlled to be discharged firstly, for example, the syrup is controlled to be discharged firstly, and when the second material is discharged, the first material is controlled to be discharged, so that the first material falls and impacts on the second material, certain buffering is realized, and the splashing degree of the first material can be reduced.
When the initial weight of the container placed below the discharge port is larger than or equal to the fifth preset weight, the actual weight of the third material contained in the container is larger than or equal to the third preset weight, the components of the beverage make mistakes, and the PLC sends out an alarm signal. The PLC can control the display color of the indicator lamp installed on the beverage machine, so that the display color of the indicator lamp is used as an alarm signal. The PLC can also send out an alarm signal through a buzzer or other devices arranged on the beverage machine.
Referring to fig. 4, in one embodiment, the step S04 of determining the first discharging speed of the first material according to the current weight includes:
step S41, obtain a first preset weight, a second preset weight and a third preset weight.
The PLC can obtain a first preset weight by analyzing the order information, and then calculate a second preset weight and a third preset weight according to the first preset weight. Of course, the order information may also include a second preset weight and a third preset weight, and the PLC may obtain the first preset weight, the second preset weight, and the third preset weight by analyzing the order information.
Step S42, comparing the current weight with a first preset weight, a second preset weight and a third preset weight respectively.
And step S43, controlling the first discharging speed to be a first preset speed under the condition that the current weight is smaller than a second preset weight.
And step S44, controlling the first discharging speed to be a first variable speed under the condition that the current weight is more than or equal to the second preset weight and less than or equal to the third preset weight, wherein the first variable speed is inversely proportional to the current weight.
And step S45, controlling the first discharging speed to be a second preset speed under the condition that the current weight is larger than a third preset weight and smaller than the first preset weight.
And step S46, controlling the first material to stop discharging when the current weight is equal to the first preset weight.
The first preset speed is greater than the first variable speed and the second preset speed, and the third preset weight is less than the first preset weight and greater than the second preset weight.
The first preset speed and the second preset speed are speed values pre-stored in the PLC. The first preset speed and the second preset speed can be set according to the weight of the first material and the size of the container. The first speed change is inversely proportional to the current weight, that is, the first speed change is reduced in the case where the current weight is increased.
Because the first preset speed is higher than the first variable speed and the second preset speed, the first material is controlled to be discharged at a higher speed under the condition that the current weight is less than the second preset weight, namely, when less beverage is contained in the container, at the moment, the liquid level of the beverage has a larger distance with the container opening, therefore, even if the discharge speed of the first material is higher, the beverage does not splash out of the cup, the discharge efficiency of the beverage can be improved, under the condition that the current weight is more than or equal to the second preset weight and less than or equal to the third preset weight, the discharge speed of the first material is controlled to be reduced along with the increase of the current weight, the discharge speed of the first material is reduced along with the reduction of the distance between the liquid level of the beverage and the container opening, the discharge speed of the first material can be adjusted according to the distance between the liquid level of the beverage and the container opening, the discharge efficiency of the beverage can be ensured, and the discharge speed of the first material can be prevented from being too fast, the beverage overflow container has the advantages that the beverage overflow container is caused, the first material is controlled to discharge at a set speed under the condition that the current weight is larger than the third preset weight and smaller than the first preset weight, the beverage can be prevented from splashing out of the cup, the beverage can be guaranteed to be filled in the container, the beverage is prevented from overflowing out of the cup, and the requirements of a user are met.
In one embodiment, the second predetermined weight may be 70% of the first predetermined weight, and the third predetermined weight may be 90% of the first predetermined weight. In other embodiments, the second predetermined weight may be 60% of the first predetermined weight, the third predetermined weight may be 95% of the first predetermined weight, and so on, which is not limited in this application.
In one embodiment, the first speed change may be calculated using the following equation:
wherein, VBecomeAt a first speed change, WAt presentTo the current weight, WTotal amount ofIs a first predetermined weight and V is a first predetermined speed. Setting the first speed change to
Thereby the ejection of compact speed of first material reduces along with the increase of current weight, and the ejection of compact speed of first material reduces along with the reduction of the distance of drink liquid level and container mouth to can guarantee the discharging efficiency of drink according to the ejection of compact speed of the first material of drink liquid level and the distance adjustment of container mouth, can also prevent that the ejection of compact speed of first material is too fast, lead to the drink to spill over outside the container.
In one embodiment, the second preset speed may be 20% of the first preset speed, that is, the discharging speed of the first material is not changed when the current weight is less than the second preset weight. In other embodiments, the second preset speed may be 18% of the first preset speed or 25% of the first preset speed, and so on, which is not limited in this application.
Referring to fig. 5, in one embodiment, the step S04 of controlling the first discharging speed of the first material according to the current weight further includes:
step S401, the subdivision of the first fluid pump motor and the first discharging speed are calculated, and a first pulse frequency is generated, wherein the first fluid pump motor is used for pumping out the first material.
Step S402 transmits a first electrical pulse at a first pulse frequency to a first fluid pump motor.
The first fluid pump motor is a stepper motor and the first fluid pump may be a peristaltic pump. The subdivision of the first fluid pump motor may be, for example, 3000 (number of pulses per revolution) and the first discharge speed VAt present，VAt presentHas a unit of r/min (revolutions per minute) and a first pulse frequency of PAt presentBecause:
therefore, the temperature of the molten metal is controlled,
Pat present＝50*VAt present
PAt presentIn units of pulses per second.
P under the condition that the current weight is less than the second preset weightAt present＝50*V。
Under the condition that the current weight is more than or equal to the second preset weight and less than or equal to the third preset weight,
in the case where the current weight is greater than the third preset weight and less than the first preset weight, and the second preset speed is equal to 20% V,
Pat present＝10*V
When the PLC obtains the first type of the first material in the order information, the PLC transmits a first electric pulse with a first pulse frequency to a first fluid pump motor corresponding to the first material of the first type.
The first material is pumped out by the fluid pump motor, and the rotating speed of the first fluid pump motor is controlled by the electric pulse, so that the discharging speed of the first material is controlled.
In the event that the current weight is equal to the first preset weight, ceasing transmission of the first electrical pulse to the first fluid pump motor.
The electric pulse is stopped being transmitted to the first fluid pump motor, so that the first fluid pump motor is controlled to stop rotating, and the first material is controlled to stop discharging.
The discharge speed of the plurality of second materials of the second type may be the same, and thus the rotational speed of the plurality of second fluid pump motors may be the same. The discharge speeds of the plurality of second materials of the second type may all be a third preset speed. The third preset speed may be pre-stored in the PLC.
The discharging control method also comprises the following steps: calculating the subdivision and the third preset speed of a second fluid pump motor to generate a second pulse frequency, wherein the second fluid pump motor is used for pumping out a second material; a second electrical pulse at a second pulse frequency is transmitted to a second fluid pump motor.
The second fluid pump motor is a stepper motor and the second fluid pump may be a peristaltic pump. If the second fluid pump motor is subdivided into 3000 (number of pulses per revolution), a third predetermined speed V3，V3Has a unit of r/min (revolutions per minute) and a second pulse frequency of P2，P2In pulses/per second, then:
P2＝50*V3
because the weights of the second materials of the second type may be different, when the discharging speeds of the second fluid pump motors corresponding to the second materials of the second type are the same, the discharging speeds of the second fluid pump motors corresponding to the second materials of the second type are different, and the discharging of the second materials is completed as the discharging of the second material with the largest weight among the second materials of the second types.
The above discharging control method is described by taking a PLC as an example, and it should be noted that the PLC in the above embodiment may be replaced by another controller.
