[0003] In the related art, during the manufacturing process of beverage containers, materials need to be weighed. Generally, an operator puts the materials into a bag placed on a weighing platform. The operator adds or subtracts the materials according to the weighing result of the weighing platform.

In this embodiment, it is preferably a conveyor belt. The flattening unit 2 is arranged above the material receiving unit 1, and the flattening unit 2 is used to flatten the material on the material receiving unit 1.

The leveling unit 3 is arranged above the material receiving unit 1 and behind the leveling unit 2. The leveling unit 3 is used to level the material. The leveling unit 3 can use a plate that can push the material or a device that absorbs and releases the material to perform fixed-point leveling or remove excess material. The weighing confirmation unit 4 is located at one end of the material receiving unit 1 in the transport direction. The weighing confirmation unit 4 is used to receive the leveled material and weigh it, and adjust and confirm the weight of the material according to the weighing result. The weighing confirmation unit 4 includes a material box for holding the material, a weighing platform for weighing the material, and an increasing and decreasing device for increasing and decreasing the weight of the material. The increasing and decreasing device can be a material spoon corresponding to different unit masses, so as to facilitate increase and decrease. The feeding unit 5 is set on one side of the weighing confirmation unit 4. The feeding unit 5 is used to move the weighed and confirmed material to a designated position and feed it.

[0031] Reference Figure 2 Based on the same inventive concept, the embodiment of the present invention provides an automatic weighing and feeding method, which is applied to Figure 1 The automatic weighing and feeding system comprises: Step S100: query and obtain the required weight value of the material at the current time.

[0032] The required weight value refers to the weight value required for weighing the material at the current time. The required weight value can be obtained through pre-input by the operator, or can be obtained after querying and analyzing other processes in the overall process steps for processing the material.

[0033] Step S200: Analyze the required weight value to determine a conveying plan, and send the conveying plan to the receiving unit 1 for execution.

[0034] Among them, the conveying plan refers to a plan used to control the material receiving unit 1 to work to transport materials. By analyzing the required weight value, the conveying plan is determined and sent to the material receiving unit 1, so that the material receiving unit 1 transports the material according to the conveying plan, which is convenient for subsequent weighing of the material.

[0035] Step S300: Acquire the paving condition information of the paved material in real time.

[0036] The flattening condition information refers to the flattening condition information of the material transported on the material docking unit 1 after the flattening process. The flattening condition information can be obtained by analyzing and detecting the image detection device preset on the flattening unit 2.

[0037] Step S400: Analyze the paving situation information and the required weight value to determine the leveling plan, and send the leveling plan to the leveling unit 3 for execution.

[0038] Among them, the leveling plan refers to the plan used to control the leveling unit 3 to level the material. By analyzing the leveling situation information and the required weight value, the leveling plan is determined and sent to the leveling unit 3, so that the leveling unit 3 can further level the leveled material, thereby facilitating the subsequent weighing of the material.

[0039] Step S500: When the weight detection value obtained in real time is equal to the required weight value, the preset feeding control information is output to the feeding unit 5 for execution.

[0040] The weight detection value refers to the weight value after the weight of the material transported to the weighing confirmation unit 4 is detected, and the weight detection value is detected and obtained by the weighing confirmation unit 4. The feeding control information refers to the control information used to control the feeding unit 5 to feed the weighed material, and the feeding control information is obtained by querying the database storing the feeding control information.

[0041] When the weight detection value obtained in real time is equal to the required weight value, it means that the weight of the material does not need to be modified at this time, so the preset feeding control information is output to the feeding unit 5, thereby controlling the feeding unit 5 to feed the material, thereby improving the overall efficiency of weighing and feeding the material.

[0042] When the conveying plan is executed and the real-time weight detection value is not equal to the required weight value, it means that there is an error that needs to be corrected. Therefore, the deviation value between the weight detection value and the required weight value is calculated and output to the weighing confirmation unit 4 for real-time adjustment, thereby reducing errors and improving the overall efficiency of weighing and feeding materials.

[0043] exist Figure 2 In step S200, in order to further ensure the rationality of the delivery plan, it is necessary to further analyze and calculate the delivery plan. Figure 3 The steps shown are explained in detail.

[0044] Reference Figure 3 , the method for determining the transportation plan includes the following steps: Step S210: Calculate the quotient between the required weight value and the preset unit time weight delivery value and use it as the initial value of the delivery time.

[0045] Among them, the initial value of the conveying time refers to the initial time value used to control the material receiving unit 1 to convey the material. The quotient between the required weight value and the preset unit time weight conveying value is calculated and used as the initial value of the conveying time, so as to facilitate subsequent use.

[0046] Step S220: Obtain the detection value of the weight per unit area.

[0047] The weight per unit area detection value refers to the weight value corresponding to the weight per unit area detected on the material receiving unit 1 , and the weight per unit area detection value is obtained by detection by a weight detection device preset on the material receiving unit 1 .

[0048] Step S230: Calculate the difference between the detected value of the weight per unit area and the preset reference value of the weight per unit area and use it as the deviation value of the weight per unit area.

[0049] The unit area weight reference value refers to the weight reference value of the material per unit area of ​​the material receiving unit 1 under normal working conditions, and the unit area weight reference value is obtained by querying the database storing the unit area weight reference value. The unit area weight deviation value refers to the deviation value when there is a deviation in the weight per unit area, and the difference between the unit area weight detection value and the preset unit area weight reference value is calculated and used as the unit area weight deviation value for subsequent use.

[0050] Step S240: Analyze the weight deviation value per unit area to determine the weight deviation impact value.

[0051] Among them, the weight deviation impact value refers to the impact value of the weight deviation on the transportation time. The weight deviation impact value is determined by analyzing the weight deviation value per unit area, which is convenient for subsequent use.

[0052] Step S250: Calculate the product of the weight deviation impact value and the initial value of the delivery time and use it as the delivery time adjustment value.

[0053] The delivery time adjustment value refers to the time value after the delivery time is adjusted. The product value between the weight deviation impact value and the initial value of the delivery time is calculated and used as the delivery time adjustment value for subsequent use.

[0054] Step S260: According to the correspondence between the delivery time adjustment value and the preset delivery time control scheme, a delivery time control scheme corresponding to the delivery time adjustment value is determined, and the delivery time control scheme is used as the delivery scheme.

[0055] The conveying time control scheme refers to a scheme for controlling the conveying time of the receiving unit 1, and the conveying time control scheme is obtained by querying the database storing the conveying time control scheme. The conveying time control scheme is determined by querying the conveying time adjustment value and used as the conveying scheme, thereby improving the accuracy of the obtained conveying scheme.

[0056] exist Figure 3 In step S240, in order to further ensure the rationality of the weight deviation impact value, it is necessary to further analyze and calculate the weight deviation impact value separately, specifically by Figure 4 The steps shown are explained in detail.

[0057] Reference Figure 4 , the method for determining the weight deviation influence value includes the following steps: Step S241: Obtain the paving type information and paving value of the paving unit 2.

[0058] The paving type information refers to the type information of the device used by the paving unit 2 when paving the material, and the paving type information is obtained by querying the database storing the paving type information. The paving number value refers to the number value of the device used by the paving unit 2 when paving the material, and the paving number value is obtained by querying the database storing the paving number value.

[0059] Step S242: determining the category benchmark impact value corresponding to the paving category information according to the correspondence between the paving category information and the preset category benchmark impact value.

[0060] The type-based impact value refers to the base impact value corresponding to different paving devices, and the type-based impact value is obtained by querying the database storing the type-based impact value. The type-based impact value is determined by querying the paving type information, which is convenient for subsequent use.

[0061] Step S243: Determine the weight deviation reference interval corresponding to the flattened number value according to the correspondence between the flattened number value and the preset weight deviation reference interval.

[0062] The weight deviation reference interval refers to the reference interval corresponding to when different paving devices flatten the material when there is a deviation in the weight of the material. The weight deviation reference interval is obtained by querying the database storing the weight deviation reference interval. The weight deviation reference interval is determined by querying the paving value, which is convenient for subsequent use.

[0063] Step S244: Analyze the unit area weight deviation value and the weight deviation reference interval to determine the required number of types.

[0064] Among them, the number of types required refers to the number of types corresponding to different leveling devices required for leveling the materials. By analyzing the weight deviation value per unit area and the weight deviation reference interval, the number of types required can be determined for subsequent use.

[0065] Step S245: Analyze the unit area weight deviation value and the category baseline influence value according to the category requirement value to determine the category comprehensive influence value, and use the category comprehensive influence value as the weight deviation influence value.

[0066] Among them, the comprehensive impact value of the type refers to the comprehensive impact value generated when different types of paving devices pave the material. The unit area weight deviation value and the type benchmark impact value are analyzed through the type requirement value, so as to determine the comprehensive impact value of the type and use it as the weight deviation impact value, thereby improving the accuracy of the obtained weight deviation impact value.

[0067] exist Figure 4 In step S244, in order to further ensure the rationality of the value of the number of category requirements, it is necessary to further analyze and calculate the value of the number of category requirements. Figure 5 The steps shown are explained in detail.

[0068] Reference Figure 5 , the method for determining the number of required values ​​of the type includes the following steps: Step S2441: Determine whether there is only one weight deviation reference interval. If yes, execute step S2442; if no, execute step S2443.

[0069] Here, by judging whether there is only one reference interval of weight deviation, it is judged whether at most three paving devices are paving the material.

[0070] Step S2442: Determine the deviation requirement value according to whether the unit area weight deviation value falls within the weight deviation reference interval, and use the deviation requirement value as the category requirement value.

[0071] Among them, the deviation requirement value refers to the number of materials that need to be leveled due to weight deviation. When there is only one weight deviation reference interval, it means that at most three leveling devices are used to level the material. Therefore, by analyzing the weight deviation value per unit area and the weight deviation reference interval, the deviation requirement value is determined and used as the type requirement value, thereby improving the accuracy of the obtained type requirement value.

[0072] Step S2443: Based on the unit area weight deviation value, the weight deviation reference interval is selected and used as the deviation falling into the reference interval.

[0073] Among them, when there is more than one weight deviation reference interval, it means that more than three kinds of leveling devices are leveling the material at this time. Therefore, the weight deviation reference interval in which the unit area weight deviation value falls is selected as the deviation falling reference interval, which is convenient for subsequent use.

[0074] Step S2444: based on whether the deviation falls into the reference interval, retrieve the interval ranking value.

[0075] Among them, the sorting value falling into the interval refers to the sorting value after the weight deviation reference interval is sorted from small to large according to the end value of the interval. The sorting value falling into the interval is retrieved by the deviation falling into the reference interval, so as to facilitate subsequent use.

[0076] Step S2445: Determine the number of falling intervals corresponding to the ranking value of the falling intervals according to the corresponding relationship between the ranking value of the falling intervals and the preset number of falling intervals, and use the number of falling intervals as the category requirement number.

[0077] The number of values ​​falling into the interval refers to the number of paving devices corresponding to the interval in which the deviation falls, and the number of values ​​falling into the interval is obtained by querying the database storing the number of values ​​falling into the interval. The number of values ​​falling into the interval is determined by querying the sorting value falling into the interval and used as the number of type requirements, thereby improving the accuracy of the obtained number of type requirements.

[0078] exist Figure 5 In step S2442 shown in the figure, in order to further ensure the rationality of the deviation requirement value, it is necessary to further analyze and calculate the deviation requirement value separately, specifically through Figure 6 The steps shown are explained in detail.

[0079] Reference Figure 6 , the method for determining the deviation requirement value includes the following steps: Step S24421: Determine whether the unit area weight deviation value is within the weight deviation reference interval. If yes, execute step S24422; if no, execute step S24423.

[0080] Among them, by judging whether the unit area weight deviation value is within the weight deviation reference interval, it is determined whether two paving devices need to be adopted.

[0081] Step S24422: Output the reference value within the preset interval and use it as the deviation requirement value.

[0082] The reference number of values ​​within the interval refers to the number of values ​​corresponding to the interval, and the reference number of values ​​within the interval refers to the number of values ​​corresponding to the time when two paving devices need to be adopted. The reference number of values ​​within the interval is obtained by querying from a database storing the reference number of values ​​within the interval. When the weight deviation value per unit area is within the weight deviation reference interval, it means that two paving devices need to be adopted at this time, so the preset reference number of values ​​within the interval is output and used as the deviation requirement number value, thereby improving the accuracy of the obtained deviation requirement number value.

[0083] Step S24423: When the weight deviation value per unit area is less than the minimum value of the weight deviation reference interval, a preset small end value reference value is output as the deviation requirement value.

[0084] Among them, the small end value benchmark number refers to the number corresponding to the number when it is less than the minimum value of the weight deviation reference interval. The small end value benchmark number here is the number corresponding to when a paving device needs to be adopted. When the unit area weight deviation value is not within the weight deviation reference interval, and the unit area weight deviation value is less than the minimum value of the weight deviation reference interval, it means that a paving device needs to be adopted at this time, so the preset small end value benchmark number is output and used as the deviation requirement number value, thereby improving the accuracy of the obtained deviation requirement number value.

[0085] Step S24424: When the weight deviation value per unit area is greater than the maximum value of the weight deviation reference interval, a preset large end value reference value is output as the deviation requirement value.

[0086] Among them, the large-end value reference number refers to the number of values ​​corresponding to when it is greater than the maximum value of the weight deviation reference interval. The large-end value reference number here is the number of values ​​corresponding to when three paving devices need to be adopted. When the unit area weight deviation value is not within the weight deviation reference interval, and the unit area weight deviation value is greater than the maximum value of the weight deviation reference interval, it means that three paving devices need to be adopted at this time, so the preset large-end value reference number is output and used as the deviation requirement number value, thereby improving the accuracy of the obtained deviation requirement number value.

[0087] exist Figure 4 In step S245, in order to further ensure the rationality of the comprehensive impact value of the category, it is necessary to further analyze and calculate the comprehensive impact value of the category. Figure 7 The steps shown are explained in detail.

[0088] Reference Figure 7 , the method for determining the comprehensive impact value of a species includes the following steps: Step S2451: Determine whether the category demand quantity value is greater than the preset demand reference quantity value. If yes, execute step S2452; if no, execute step S2457.

[0089] The demand base number value refers to the base number value corresponding to when there is only one type of demand to be leveled, and the demand base number value is obtained by querying the database storing the demand base number values. By judging whether the type demand number value is greater than the preset demand base number value, it is judged whether the impact value can be directly analyzed and calculated based on the type demand number value.

[0090] Step S2452: based on the value of the number of type requirements, the corresponding weight deviation reference interval is retrieved and used as the number reference interval, and based on the value of the number of type requirements, the corresponding type reference influence value is used as the number reference influence value.

[0091] Among them, the number reference interval refers to the weight deviation reference interval corresponding to different numbers, and the number reference impact value refers to the type reference impact value corresponding to the paving device used at different numbers. When the type demand value is greater than the preset demand reference value, it means that the impact value cannot be directly analyzed and calculated based on the type demand value. Therefore, the number reference interval and number reference impact value are retrieved and defined to facilitate subsequent use.

[0092] Step S2453: Determine the interval-based influence value corresponding to the number-based interval according to the correspondence between the number-based interval and the preset interval-based influence value.

[0093] The interval benchmark impact value refers to the benchmark impact value corresponding to each different number of overall intervals, and the interval benchmark impact value is obtained by querying the database storing the interval benchmark impact value. The interval benchmark impact value is determined by querying the number benchmark interval, which is convenient for subsequent use.

[0094] Step S2454: Calculate the deviation between the unit area weight deviation value and the maximum number reference interval and use it as the interval deviation value.

[0095] Among them, the interval deviation value refers to the deviation value when there is a deviation between the weight deviation and the interval. The deviation value between the unit area weight deviation value and the maximum number reference interval is calculated and used as the interval deviation value for convenience in subsequent use.

[0096] Step S2455: Calculate the product of the interval deviation value and the number benchmark impact value and use it as the interval deviation impact value.

[0097] Among them, the interval deviation impact value refers to the impact degree value of the deviation part when there is a deviation in the interval. The product value between the interval deviation value and the number benchmark impact value is calculated and used as the interval deviation impact value for convenience in subsequent use.

[0123] Among them, the gap filling control information refers to the control information used to fill the gap. When the gap area deviation value is greater than the preset gap area deviation reference value, it means that the gap meets the weight requirement at this time.

[0134] The convex filling control information refers to the control information for indicating that the gap is filled with convexities, and the convex filling control information is obtained by querying from a database storing the convex filling control information. When the convex area deviation value is less than the preset convex area deviation reference value, it means that it is not necessary to remove the convexities at this time, so the convex filling control information is determined by querying the convex type area value, which is convenient for subsequent use.

[0140] Among them, the protrusion single control information refers to the single control information used to fill the gap with the protrusion. When the protrusion area deviation value is not less than the preset protrusion area deviation reference value, it means that only the protrusion needs to be removed at this time.
