Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and in particular to an intelligent conveying device for food and beverage production. Background Art

[0002] Currently, most of the food and beverages sold on the market are made of water as the basic raw material, supplemented with other edible auxiliary materials through different proportions and production processes. There are many types of beverages, and common beverages on the market include cola, juice, Sprite and coffee. The production process of beverages requires a series of production processes, usually pouring edible liquid into a container, then sealing the container, and then sticking the production label on the outer wall of the container to form a complete drink that can be sold.

[0003] At present, beverage production lines usually have multiple intelligent conveying devices installed to complete a series of production processes. Among them, labeling the sealed container containing beverages is an important part of the production process. Only labeled beverages can be sold. However, the self-inspection of labeling in the current production process mostly relies on subsequent manual inspection, which is laborious and inefficient, and there is a lack of adjustment means for the entire production line to improve the efficiency of labeling. Summary of the invention

[0004] To this end, the present invention provides an intelligent conveying device for food and beverage production, which is used to solve the problem in the prior art that there is a lack of effective detection means and corresponding correction means in the labeling process in beverage production.

[0005] To achieve the above-mentioned object, the present invention provides an intelligent conveying device for food and beverage production, comprising:

[0006] A conveying device for conveying packaged beverages;

[0007] a differential conveyor belt group connected to the output end of the conveying device, comprising a plurality of conveyor belts arranged in parallel for conveying the packaged beverage, each conveyor belt having a different conveying speed;

[0008] A limiting device, which is arranged on one side above the differential conveyor belt group and is used to restrict the moving path of the packaged beverage;

[0009] a labeling device, which is arranged at the output end of the differential conveyor belt set and is used to label the side of the packaged beverage;

[0010] A detection device, which is arranged on one side of the labeling device and is used to identify the label on the labeled beverage;

[0011] a recovery device, which is arranged on the other side of the label device and connected to the detection device, and is used to recover the unlabeled beverage based on the identification result of the detection device;

[0012] an analysis unit connected to the recycling device, for determining whether the labeling process of the labeling device meets the standard based on the amount of recycled beverages, and determining a corresponding processing method based on the determination result, including: outputting the labeled beverage if it is determined to meet the standard, or generating a corresponding instruction based on the determined reason for not meeting the standard;

[0013] A control unit, which is respectively connected to the analysis unit, the differential conveyor belt group, the limit device, the labeling device and the detection device, and is used to adjust the operating parameters of the corresponding devices based on the instructions generated by the analysis unit, and the parameters include: the speed of the differential conveyor belt group, the angle between the limit device and the conveying direction of the packaged beverage, the labeling speed of the labeling device and the detection standard of the detection device.

[0014] Furthermore, the analysis unit is also used to determine whether the labeling process of the labeling device meets the standards based on a comparison result of the number of recovered drinks by the recovery device in a current detection cycle and a preset number of recovered drinks pre-stored in the analysis unit, or based on a ratio of the number of recovered drinks to the number of labeled drinks in the detection cycle, and, if it is determined that the labeling process of the labeling device does not meet the standards, determine the reason for non-compliance with the standards based on the difference in the number of recovered drinks, wherein the difference in the number of recovered drinks is the difference between the number of recovered drinks and the preset number of recovered drinks.

[0015] Furthermore, the analysis unit is also used to re-judge based on the comparison result of the recovered beverage quantity ratio and the preset recovered beverage quantity ratio pre-stored in the analysis unit, and when the labeling process of the labeling device does not meet the standards, determine to extend the current detection period based on the ratio difference, wherein the recovered beverage quantity ratio is the ratio between the recovered beverage quantity and the labeled beverage quantity, and the ratio difference is the difference between the preset recovered beverage quantity ratio and the recovered beverage quantity ratio.

[0016] Furthermore, the analysis unit is also used to extend and correct the current detection period to a corresponding value based on a comparison result of the ratio difference with a preset ratio difference pre-stored in the analysis unit, and the extension range of the detection period is proportional to the ratio difference.

[0017] Furthermore, the analysis unit is also used to determine the reason why the labeling process of the labeling device does not meet the standards based on the comparison result of the recovered beverage quantity difference with the preset recovered beverage quantity difference pre-stored in the analysis unit, and generate a corresponding correction method based on the determined reason, including: adjusting the labeling speed increase rate for the labeling device, or, reducing the speed for the differential conveyor belt group, or, redetermining the reason according to several time nodes of the recovered beverages within the current detection cycle.

[0018] Furthermore, the analysis unit is also used to determine that the labeling speed of the labeling device is increased to a corresponding value based on a comparison result between the recovered beverage quantity and a preset correction beverage quantity pre-stored in the analysis unit, and the increase in the labeling speed of the labeling device is proportional to the recovered beverage quantity.

[0019] Furthermore, the analysis unit is also used to determine the reason why the labeling process of the labeling device does not meet the standards based on the comparison result of the time interval average value and the preset time interval average value, and to generate a corresponding correction method based on the determined reason, including: adjusting the labeling speed increase rate for the labeling device, or adjusting the image processing parameters of the detection device, wherein the time interval average value is obtained through several time nodes of the recovered beverages within the current detection cycle.

[0020] Furthermore, the analysis unit is also used to determine the optimization of the image processing parameters for the detection device to corresponding values ​​based on the comparison result of the average value difference with the preset average value difference pre-stored in the analysis unit, wherein the average value difference is the difference between the preset time interval average value and the time interval average value, and the image processing parameters include noise reduction.

[0021] Furthermore, the analysis unit is also connected to the conveying device, and the analysis unit is further used to determine that the speed of the differential conveyor belt group is reduced to a corresponding value based on a comparison result of the total number of packaged beverages and a preset total number of packaged beverages, and the reduction range of the conveyor belt speed is proportional to the total number of packaged beverages, wherein the total number of packaged beverages is the total number of packaged beverages conveyed from the conveying device to the differential conveyor belt group in the current detection cycle;

[0022] The speeds of the plurality of conveyor belts in the differential conveyor belt set are synchronously reduced in a proportional relationship.

[0023] Furthermore, the analysis unit is also used to increase the angle between the limiting device and the conveying direction of the differential conveyor belt group based on the speed reduction amplitude of the differential conveyor belt group, and the increase amplitude of the angle is proportional to the speed reduction amplitude.

[0024] Compared with the prior art, the beneficial effect of the intelligent conveying device for food and beverage production of the present invention is that the device conveys the packaged beverage to the labeling device through a differential conveyor belt group, and the label is attached to the outer wall of the packaged beverage by the labeling device. At the same time, the detection device identifies whether the labeled beverage is labeled. When an unlabeled beverage is identified, the beverage is taken out by a recovery device, and the analysis unit determines whether the labeling process of the labeling device meets the standards based on the number of recovered beverages, and when it is determined that the labeling process of the labeling device does not meet the standards, the reason for the non-compliance is determined based on the number of recovered beverages, a corresponding correction method is generated based on the reason, and a corresponding instruction is generated based on the correction method. The control unit adjusts the operating parameters of the corresponding device based on the instruction to improve the accuracy of the detection process, or to improve the labeling efficiency of the labeling device.

[0025] Furthermore, in addition to determining whether the labeling process of the labeling device meets the standards based on the number of recovered beverages, the present invention also determines whether the labeling process of the labeling device meets the standards based on the ratio of the number of recovered beverages to the number of labeled beverages within a detection period. This can avoid misjudgment and improve the accuracy of determining whether the labeling process meets the standards.

[0026] Furthermore, when the present invention determines that the labeling process of the labeling device meets the standards during the re-determination process, it also extends the current detection period based on the ratio difference. The extension of the detection period is proportional to the ratio difference. This can increase the number of samples in the determination process, thereby improving the accuracy of the determination process.

[0027] Furthermore, the present invention specifically determines the reason why the labeling process of the labeling device does not meet the standards based on the difference in the number of recovered beverages, and generates a corresponding correction method, so that targeted adjustments can be made to improve the labeling efficiency of the labeling device and reduce the number of unqualified recovered beverages.

[0028] Furthermore, the present invention also determines to increase the labeling speed of the labeling device based on the amount of recovered beverages, thereby improving the labeling efficiency of the labeling device.

[0029] Furthermore, the present invention also re-determines the reason why the labeling process of the labeling device does not meet the standard based on the time interval average value, and generates a corresponding correction method, thereby reducing the number of recycled drinks.

[0030] Furthermore, the present invention also optimizes and adjusts the image processing parameters of the detection device based on the average value difference, thereby improving the detection accuracy of label recognition for beverages.

[0031] Furthermore, the present invention also determines to reduce the speed of the differential conveyor belt group based on the total number of packaged beverages, thereby reducing the number of packaged beverages entering the labeling device per unit time, thereby ensuring that the packaged beverages entering the labeling device can be labeled, thereby improving the accuracy of the labeling device in labeling the packaged beverages.

[0032] Furthermore, the present invention also determines to increase the angle between the limit device and the conveying direction of the differential conveyor belt based on the speed reduction amplitude of the differential conveyor belt, and controls the number of packaged beverages entering the labeling device per unit time by adjusting the angle, thereby improving the accuracy of the labeling device in labeling the packaged beverages.

[0044] See also Figure 1 and Figure 2 As shown, Figure 1 is a schematic diagram of a module of an intelligent conveying device for food and beverage production in this embodiment, Figure 2It is a schematic diagram of the structure of the intelligent conveying device for food and beverage production in this embodiment. The production line 1 in the device includes: a conveying device 11, a differential conveyor belt group 12, a limit device 13, a labeling device 14, a detection device 15, a recovery device 16, an analysis unit, and a control unit. The conveying device 11 is used to convey packaged beverages; the differential conveyor belt group 12 is connected to the output end of the conveying device 11, and includes a plurality of parallel conveyor belts 121 for conveying the packaged beverages, and the conveying speeds of the conveyor belts 121 are different; the limit device 13 is arranged on one side above the differential conveyor belt group 12 to constrain the moving path of the packaged beverage; the labeling device 14 is arranged on the output end of the differential conveyor belt group 12 to label the side of the packaged beverage; the detection device 15 is arranged on one side of the labeling device 14 to identify the label on the labeled beverage; the recovery device 16 is arranged on the other side of the labeling device 14 and connected to the detection device 15 to recover the unlabeled beverage based on the recognition result of the detection device 15 The analysis unit is connected to the recovery device 16 to determine whether the labeling process of the labeling device 14 meets the standards based on the number of recovered beverages, and to determine the corresponding processing method based on the determination result, including: outputting the labeled beverage if it is determined to meet the standards, or generating corresponding instructions based on the determined reasons for non-compliance with the standards; the control unit is respectively connected to the analysis unit, the differential conveyor belt group 12, the limit device 13, the labeling device 14 and the detection device 15, to adjust the operating parameters of the corresponding devices based on the instructions generated by the analysis unit, and the parameters include: the speed of the differential conveyor belt group 12, the angle between the limit device 13 and the conveying direction of the packaged beverage, the labeling speed of the labeling device 14 and the detection standard for the detection device 15.

[0045] Specifically, in this embodiment, the production line 1 includes a conveying device 11, through which the packaged beverage is conveyed to the differential conveyor belt group 12 after packaging. The differential conveyor belt group 12 conveys the packaged beverage to the labeling device 14 through a plurality of conveyor belts 121. A limiting device 13 is provided on the differential conveyor belt group 12, and the limiting device 13 is used to make the packaged beverage move along the corresponding path. The limiting device 13 includes a limiting plate 131 connected at an angle to the conveying direction of the conveyor belt 121. The limiting plate 131 adjusts the angle between the limiting plate 131 and the conveying direction based on the operation of the labeling device 14 to control the number of packaged beverages conveyed from the conveyor belt 121 to the labeling device 14 per unit time. The labeling device 14 labels the packaged beverage conveyed by the differential conveyor belt group 12. Specifically, the labeling device 14 is connected to a conveyor belt 121 in the differential conveyor belt group 12 and receives the packaged beverage conveyed by the conveyor belt 121, and then conveys the labeled beverage to the next link in the entire production line 1. During the labeling process, the label on the beverage is detected by the detection device 15 arranged on one side of the labeling device 14, and the image recognition function of the detection device 15 is used to detect whether the beverage is labeled. When an unlabeled beverage is detected, the unlabeled beverage is taken out and recycled by the recovery device 16 arranged on the other side of the labeling device 14. The recycled beverage is the unlabeled beverage. The recovery device 16 is configured as a mechanical arm group including a plurality of mechanical arms 161. The mechanical arms 161 take out the unlabeled beverage from the labeling device 14 to ensure that the beverages transported by the labeling device 14 in the subsequent transport link are all qualified products with labels. An analysis unit (not shown in the figure) is also provided in the production line 1, which determines whether the labeling process of the labeling device 14 meets the standard by the number of recycled beverages. When it is determined that the labeling process does not meet the standard, the reason for the non-compliance can be determined, and a corresponding correction method is generated based on the reason, and a corresponding instruction is generated based on the correction method, and then the instruction is sent to the control unit (not shown in the figure). The operating parameters of the differential conveyor belt group 12, the limiting device 13, the labeling device 14, and the detection device 15 are adjusted respectively by the control unit, and the labeling process of the labeling device 14 is qualified or the determination process of the labeling process of the labeling device 14 is accurate by adjusting the corresponding devices. The specific adjustment process is: adjusting the conveying speed of each conveyor belt 121, adjusting the angle between the limiting plate 131 and the conveying direction of the packaged beverage, adjusting the labeling speed of the labeling device 14, and optimizing the image processing parameters of the detection device 15.

[0046] The production line 1 also includes a buffer zone 2 disposed on one side of the differential conveyor belt set 12. The buffer zone 2 is close to one end of the labeling device 14 and away from the conveying device 11, and is used to temporarily receive the packaged beverages. When the conveyor belt 121 moves at a reduced speed, in order to prevent subsequent packaged beverages from being blocked during movement on the differential conveyor belt set 12, a buffer zone 2 is provided to receive additional packaged beverages, thereby reducing the number of beverages crowded on the differential conveyor belt set 12. After the labeling device 14 improves the efficiency of labeling the beverages, the beverages in the buffer zone 2 are transported to the labeling device 14 to continue the labeling operation. Figure 3 As shown, it is a flow chart of determining whether the labeling process of the labeling device 14 meets the standard based on the number of recovered drinks in this embodiment. The analysis unit is also used to determine whether the labeling process of the labeling device 14 meets the standard based on the comparison result of the number of recovered drinks of the recovery device 16 in the current detection cycle and the preset number of recovered drinks pre-stored in the analysis unit, or based on the ratio of the number of recovered drinks to the number of labeled drinks in the detection cycle, and, if it is determined that the labeling process of the labeling device 14 does not meet the standard, determine the reason for not meeting the standard based on the difference in the number of recovered drinks, wherein the difference in the number of recovered drinks is the difference between the number of recovered drinks and the preset number of recovered drinks.

[0047] Specifically, in this embodiment, the preset number of recovered drinks includes a first preset number of recovered drinks and a second preset number of recovered drinks, the first preset number of recovered drinks is less than the second preset number of recovered drinks, and the comparison result based on the number of recovered drinks and the preset number of recovered drinks is as follows:

[0048] If the number of recovered drinks is less than or equal to the first preset number of recovered drinks, it means that the number of unlabeled drinks is within an acceptable range, that is, the number of labeled drinks can meet the subsequent production needs, and it can be determined that the labeling process of the labeling device 14 meets the standards; if the number of recovered drinks is greater than the first preset number of recovered drinks and is less than or equal to the second preset number of recovered drinks, it is impossible to accurately determine whether the number of unlabeled drinks is within an acceptable range at this time, and it is necessary to re-determine whether the labeling process of the labeling device 14 meets the standards through the ratio of the number of recovered drinks to the number of labeled drinks in the current detection cycle; if the number of recovered drinks is greater than the second preset number of recovered drinks, it means that the number of unlabeled drinks is too large and exceeds the acceptable range, then it is determined that the labeling process of the labeling device 14 does not meet the standards, and at this time it is necessary to determine the reason for non-compliance based on the difference in the number of recovered drinks. The difference in the number of recovered drinks at this time is specifically the difference between the number of recovered drinks and the second preset number of recovered drinks.

[0049] In this embodiment, in a single detection cycle, the first preset number of recovered drinks and the second preset number of recovered drinks are respectively assigned 20 and 30. It should be noted that, in other embodiments, the assignment of the first preset number of recovered drinks and the second preset number of recovered drinks is determined according to specific production conditions and is not specifically limited here.

[0050] See also Figure 4 As shown, it is a flowchart of determining the reasons why the labeling process of the labeling device 14 does not meet the standards and the corrections based on the ratio of the number of recovered drinks in this embodiment. The analysis unit is also used to re-determine based on the comparison result of the ratio of the number of recovered drinks and the preset ratio of the number of recovered drinks pre-stored in the analysis unit, and in the case that the labeling process of the labeling device 14 does not meet the standards, determine to extend the current detection period based on the ratio difference, wherein the ratio of the number of recovered drinks is the ratio between the number of recovered drinks and the number of labeled drinks, and the ratio difference is the difference between the preset ratio of the number of recovered drinks and the ratio of the number of recovered drinks.

[0051] Specifically, in this embodiment, the comparison process based on the ratio of the number of recovered drinks and the preset ratio of the number of recovered drinks is as follows:

[0052] If the ratio of the number of recovered drinks is less than or equal to the preset ratio of the number of recovered drinks, although it can be determined that the labeling process of the labeling device 14 meets the standards, the ratio of the number of unlabeled drinks can indirectly determine that the number of labeled drinks actually delivered in the current detection cycle is small, and the number of samples for judgment is small. Therefore, the detection cycle can be extended to increase the number of samples, thereby improving the accuracy of the judgment; if the ratio of the number of recovered drinks is greater than the preset ratio of the number of recovered drinks, it means that the number of unlabeled drinks in the current detection cycle is too large, and therefore it can be determined that the labeling process of the labeling device 14 does not meet the standards.

[0053] In this embodiment, the preset value of the ratio of the number of recovered drinks is 0.001. It should be noted that, in other embodiments, the preset value of the ratio of the number of recovered drinks is determined according to specific production conditions and is not specifically limited here.

[0054] Furthermore, the analysis unit is also used to extend and correct the current detection period to a corresponding value based on a comparison result of the ratio difference with a preset ratio difference pre-stored in the analysis unit, and the extension range of the detection period is proportional to the ratio difference.

[0055] Specifically, in this embodiment, the preset ratio difference includes a first preset ratio difference and a second preset ratio difference greater than the first preset ratio difference, and the comparison process based on the ratio difference and the preset ratio difference is as follows:

[0056] If the ratio difference is less than or equal to the first preset ratio difference, the control unit uses the first detection period adjustment coefficient to extend the detection period of the detection device 15 to 1.5 times the initial value; if the ratio difference is greater than the first preset ratio difference and less than or equal to the second preset ratio difference, the control unit uses the second detection period adjustment coefficient to extend the detection period of the detection device 15 to 2 times the initial value; if the ratio difference is greater than the second preset ratio difference, the control unit uses the third detection period adjustment coefficient to extend the detection period of the detection device 15 to 2.5 times the initial value. By extending the detection period to obtain more samples, the result of re-determining whether the labeling process of the labeling device 14 meets the standard based on the ratio of the number of unlabeled beverages is more accurate.

[0057] It should be noted that, in other embodiments, the detection cycle extension value is determined according to the specific production situation, with the goal of improving the determination accuracy of the labeling process, and is not specifically limited here.

[0058] Furthermore, the analysis unit is also used to determine the reason why the labeling process of the labeling device 14 does not meet the standards based on the comparison result of the recovered beverage quantity difference with the preset recovered beverage quantity difference pre-stored in the analysis unit, and generate a corresponding correction method based on the determined reason, including: adjusting the labeling speed increase of the labeling device 14, or reducing the speed of the differential conveyor belt group 12, or redetermining the reason according to several time nodes of the recovered beverages within the current detection cycle.

[0059] Specifically, in this embodiment, the preset difference in the number of recovered drinks includes a first preset difference in the number of recovered drinks and a second preset difference in the number of recovered drinks that is greater than the first preset difference in the number of recovered drinks. The comparison process based on the difference in the number of recovered drinks and the preset difference in the number of recovered drinks is as follows:

[0060] If the difference in the number of recovered drinks is less than or equal to the first preset difference in the number of recovered drinks, it can be determined that the speed of labeling by the labeling device 14 has decreased, resulting in some drinks not being labeled. At this time, the analysis unit can issue a corresponding instruction and send a signal to the labeling device 14 through the control unit to increase the labeling speed of the labeling device 14, thereby reducing the number of recovered drinks and making the labeling process meet the standard; if the difference in the number of recovered drinks is greater than the first preset difference in the number of recovered drinks and is less than or equal to the second preset difference in the number of recovered drinks, it is impossible to accurately determine the corresponding correction method at this time, and it is necessary to determine the number of recovered drinks by the recovery device 16 in the current detection cycle. The time nodes corresponding to the products are calculated and compared, so as to re-determine the reason why the labeling process does not meet the standards; if the difference in the number of recovered beverages is greater than the second preset difference in the number of recovered beverages, it can be determined that the conveying speed of the conveyor belt 121 is too fast, resulting in some beverages not being labeled. At this time, the analysis unit can issue a corresponding instruction and send a signal to the differential conveyor belt group 12 through the control unit to reduce the speed of each conveyor belt 121 in the differential conveyor belt group 12, so that the number of beverages entering the labeling device 14 per unit time is relatively reduced, which can ensure that the labeling device 14 labels the beverages in time, thereby improving the labeling efficiency of packaged beverages.

[0061] In this embodiment, the first preset difference in the number of recovered drinks and the second preset difference in the number of recovered drinks are respectively assigned values ​​of 3 and 5. It should be noted that, in other embodiments, the assignment of the first preset difference in the number of recovered drinks and the second preset difference in the number of recovered drinks is determined according to specific production conditions and is not specifically limited here.

[0062] Furthermore, the analysis unit is also used to determine that the labeling speed of the labeling device 14 is increased to a corresponding value based on the comparison result of the recovered beverage quantity and the preset correction beverage quantity pre-stored in the analysis unit, and the increase in the labeling speed of the labeling device 14 is proportional to the recovered beverage quantity.

[0063] Specifically, in this embodiment, the preset calibration beverage quantity includes a first preset calibration beverage quantity and a second preset calibration beverage quantity greater than the first preset calibration beverage quantity. The comparison process based on the recovered beverage quantity and the preset calibration beverage quantity is as follows:

[0064] If the number of recovered drinks is less than or equal to the first preset correction drink number, the control unit uses the first labeling speed adjustment coefficient to increase the labeling speed of the labeling device 14 to 1.35 times the initial value; if the number of recovered drinks is greater than the first preset correction drink number and less than or equal to the second preset correction drink number, the control unit uses the second labeling speed adjustment coefficient to increase the labeling speed of the labeling device 14 to 1.55 times the initial value; if the number of recovered drinks is greater than the second preset correction drink number, the control unit uses the third labeling speed adjustment coefficient to increase the labeling speed of the labeling device 14 to 2.15 times the initial value.

[0065] In this embodiment, the first preset correction number of beverages and the second preset correction number of beverages are assigned values ​​of 10 and 30 respectively; the labeling speed of the labeling device 14 is adjusted by comparing the number of recovered beverages with the preset correction number of beverages, thereby improving the labeling efficiency of the labeling device 14. In other embodiments, the first preset correction number of beverages, the second preset correction number of beverages, and the labeling speed increase ratio of the labeling device 14 are determined by specific production conditions and are not specifically limited here.

[0066] Furthermore, the analysis unit is also used to determine the reason why the labeling process of the labeling device 14 does not meet the standards based on the comparison result of the time interval average value and the preset time interval average value, and generate a corresponding correction method based on the determined reason, including: adjusting the labeling speed increase rate of the labeling device 14, or adjusting the image processing parameters of the detection device 15, wherein the time interval average value is obtained through several time nodes of the recovered beverages in the current detection cycle.

[0067] Specifically, in this embodiment, if the time interval average value is less than or equal to the preset time interval average value, it means that the time node intervals at which the recovered drinks are taken out by the recovery device 16 are relatively close, that is, the unlabeled drinks are relatively concentrated in the current detection cycle, and the labeling speed of the labeling device 14 cannot keep up with the conveying speed of the packaged drinks in the current cycle. At this time, the control unit can adjust the labeling speed of the labeling device 14 to reduce the number of recovered drinks; if the time interval average value is greater than the preset time interval average value, it means that the time node intervals at which the recovered drinks are taken out by the recovery device 16 are relatively far, that is, the unlabeled drinks are relatively scattered in the current detection cycle, and there may be unlabeled drinks that are not identified by the detection device 15, which will result in missed recovered drinks. At this time, the control unit should optimize the processing parameters for acquiring image information of the detection device 15 to enhance the detection function of the detection device 15 and avoid too many unlabeled drinks from entering the next production link.

[0068] Specifically, in this embodiment, a single detection cycle can be set to 1 hour, and the preset time interval average value is assigned to 10 minutes. In other embodiments, the preset time interval average value is determined according to specific production conditions and is not specifically limited here.

[0069] Furthermore, the analysis unit is also used to determine the optimization of the image processing parameters for the detection device 15 to corresponding values ​​based on the comparison result of the average value difference with the preset average value difference pre-stored in the analysis unit, wherein the average value difference is the difference between the time interval average value and the preset time interval average value, and the image processing parameters include noise reduction.

[0070] Specifically, in this embodiment, the preset average value difference includes a first preset average value difference and a second preset average value difference, the first preset average value difference is smaller than the second preset average value difference, and the comparison process based on the average value difference and the preset average value difference is as follows:

[0071] If the average value difference is less than or equal to the first preset average value difference, the control unit uses the first parameter adjustment coefficient to increase the noise reduction ratio of the detection device 15 to 1.23 times the initial value; if the average value difference is greater than the first preset average value difference and less than or equal to the second preset average value difference, the control unit uses the second parameter adjustment coefficient to increase the noise reduction ratio of the detection device 15 to 1.45 times the initial value; if the average value difference is greater than the second preset average value difference, the control unit uses the third parameter adjustment coefficient to increase the noise reduction ratio of the detection device 15 to 1.64 times the initial value. The image processing capability of the detection device 15 is enhanced by increasing the noise reduction ratio, so that the detection accuracy of the detection device 15 for beverages is improved. In other embodiments, the image processing parameters may also be parameters such as sharpening, particle amount, and clarity.

[0072] Specifically, in this embodiment, the first preset average value difference and the second preset average value difference are assigned values ​​of 1 minute and 3 minutes, respectively. In other embodiments, the first preset average value difference and the second preset average value difference and the increase ratio of the noise reduction ratio of the detection device 15 are determined according to specific production conditions and are not specifically limited here.

[0073] Furthermore, the analysis unit is also connected to the conveying device 11, and is further used to determine, based on the comparison result of the total number of packaged beverages and the preset total number of packaged beverages, that the speed of the differential conveyor belt set 12 is reduced to a corresponding value, and the speed reduction amplitude of the conveyor belt 121 is proportional to the total number of packaged beverages, wherein the total number of packaged beverages is the total number of packaged beverages conveyed from the conveying device 11 to the differential conveyor belt set 12 in the current detection cycle;

[0074] The speeds of the plurality of conveyor belts 121 in the differential conveyor belt set 12 are synchronously reduced in a proportional relationship.

[0075] Specifically, in this embodiment, the total number of preset packaged beverages includes the total number of first preset packaged beverages and the total number of second preset packaged beverages that is greater than the total number of first preset packaged beverages. The comparison process based on the total number of packaged beverages and the total number of preset packaged beverages is as follows:

[0076] If the total number of packaged beverages is less than or equal to the first preset total number of packaged beverages, the first conveyor belt speed adjustment coefficient is used to reduce the speed of the conveyor belt 121 to 0.95 times the initial value; if the total number of packaged beverages is greater than the first preset total number of packaged beverages and less than or equal to the second preset total number of packaged beverages, the second conveyor belt speed adjustment coefficient is used to reduce the speed of the conveyor belt 121 to 0.90 times the initial value; if the total number of packaged beverages is greater than the second preset total number of packaged beverages, the third conveyor belt speed adjustment coefficient is used to reduce the speed of the conveyor belt 121 to 0.85 times the initial value. Reducing the speed of the differential conveyor belt group 12 is actually to reduce the speed of each conveyor belt 121. By reducing the speed of each conveyor belt 121, the number of packaged beverages entering the label device 14 per unit time is reduced, thereby reducing the pressure of the label device 14 in the current state to apply labels, and increasing the number of qualified labeled beverages. Since the labeling device 14 is connected to one or more of the conveyor belts 121, and the moving path of the packaged beverage on the differential conveyor belt group 12 is limited by the limit device 13, when the speed of each conveyor belt 121 is reduced, it is necessary to ensure that the speeds of each conveyor belt 121 are reduced synchronously in a proportional relationship to ensure that each conveyor belt 121 after the speed reduction can transport the packaged beverage to the labeling device 14.

[0077] Specifically, in this embodiment, the total number of the first preset packaged beverages and the total number of the second preset packaged beverages in a single detection cycle are respectively assigned 1000 and 1100. In other embodiments, the total number of the first preset packaged beverages and the total number of the second preset packaged beverages and the multiple of the speed reduction of the conveyor belt 121 are determined according to specific production conditions and are not specifically determined here.

[0078] Furthermore, the analysis unit is also used to increase the angle between the limiting device 13 and the conveying direction of the differential conveyor belt set 12 based on the speed reduction amplitude of the differential conveyor belt set 12, and the increase amplitude of the angle is proportional to the speed reduction amplitude.

[0079] Specifically, in this embodiment, the greater the speed reduction of the differential conveyor belt set 12, the slower the conveying speed of each conveyor belt 121. At this time, the angle between the limiting device 13 and the conveying direction can be increased. Specifically, the limiting device 13 includes a limiting plate 131, such as Figure 2As shown, when the limit plate 131 rotates around its rotation axis in a direction parallel to the horizontal plane, it forms an angle with the differential conveyor belt 12. Specifically, the angle between the limit plate 131 and the conveying direction is adjusted accordingly as the speed of the conveyor belt 121 changes, thereby changing the moving path of the packaged beverage on the differential conveyor belt group 12. By changing the moving path, the number of packaged beverages entering the labeling device 14 per unit time is affected. The larger the angle, the fewer the number of packaged beverages entering the labeling device 14 per unit time, which is beneficial for the subsequent labeling device 14 to accurately attach the label to the packaged beverage, thereby improving the labeling efficiency of the packaged beverage.
