[0002] At present, in the liquid product filling production line, the commonly used detection method is to use a liquid level sensor to detect the liquid level height of the liquid product, and judge whether the liquid level reaches the preset standard by sensing the presence of liquid.

[0003] The existing liquid level sensor detection method mainly measures the liquid level by sensing the presence of liquid products, which is used as the basis for judging whether the filling volume meets the standard. However, although this method can roughly determine the liquid level position, in actual applications, its detection accuracy is not high, and when the liquid level is abnormal, it is impossible to determine which filling port has a problem.

[0004] The above-mentioned prior art solutions have the following defects: When a problem with the liquid level is discovered, it is impossible to quickly and accurately locate the abnormal filling port, which increases the difficulty and time cost of subsequent maintenance and adjustments. Summary of the invention

[0005] In order to improve the accuracy of liquid level detection and thus quickly locate the abnormal filling port when an abnormality occurs, the present application provides a liquid product identification detection and weighing device and a weighing method thereof.

[0007] By adopting the above technical scheme and providing a weighing device, it is possible to directly judge whether the amount of liquid concerned by the filling head is qualified according to the weight of the product during the product weight inspection, so that the amount of weight deviation in the unqualified product can be obtained more directly. At the same time, the weighing method is not affected by the deformation of the bottle body of the packaging bottle and the thickness of the bottle body. Furthermore, the identification device is provided, which can carry the information of the filling head on the identification code sprayed on the product. After detecting the abnormality of weight, the abnormal filling head can be quickly located by scanning the identification code, so that while improving the accuracy of liquid level detection, it is also easy to quickly locate the abnormal filling head, and then facilitate corresponding maintenance.

[0008] In a preferred example, the present application can be further configured as follows: the identification device includes a spray head and a visual detection device for detecting the position of the product, and the spray head is arranged on a side of the visual detection device facing the product transportation device.

[0009] By adopting the above technical solution and providing a visual detection device, the identification code can be sprayed when the product is facing the nozzle during the spraying process of the nozzle, so as to facilitate subsequent identification.

[0010] In a preferred example, the present application can be further configured as follows: the rejection device includes a conveyor belt and a cylinder, the conveyor belt is arranged at the discharge end of the weighing device, and the transmission direction is consistent with the transmission direction of the product transport device, the cylinder is arranged on one side of the conveyor belt, and the pushing direction of the cylinder is perpendicular to the transmission direction of the conveyor belt.

[0011] By adopting the above technical solution, when unqualified products need to be rejected, the unqualified products by weight can be rejected by means of cylinder pushing.

[0012] The above-mentioned second objective of the present application is achieved through the following technical solutions: A weight checking method applied to the above device, the weight checking method comprising: Obtain product weighing information, compare the product weighing information with a preset product weight standard, and obtain a product weighing result, wherein the product weighing result includes a qualified weighing result and an unqualified weighing result; Generate a defective product rejection instruction for the unqualified product according to the weighing result of the product, so as to control the rejection device to reject the corresponding product, and obtain the product identification code of the rejected product as the identification code to be identified; Counting the identification codes to be identified according to a predetermined time period, and identifying the identification codes to be identified to obtain identification code identification information; The identification code identification information is parsed to obtain an abnormal injection head identifier, and a injection head maintenance message is triggered according to the abnormal injection head identifier.

[0013] By adopting the above technical solution, after weighing, the product weighing information is obtained, and unqualified products are eliminated according to the compared product weighing results. At the same time, after counting a certain amount of unqualified products, the product identification codes are centrally identified, so that the identification of the abnormal filling head can be analyzed, and then the unqualified products can be quickly obtained while the abnormal filling head can be located, which is convenient for subsequent maintenance.

[0015] By adopting the above technical solution, since in the production process of packaging bottles, even qualified products will have certain errors in their weight, the average packaging weight is used as the standard packaging weight, the average weight of the packaging bottles can be used as a benchmark, and the packaging weight range is used as the error range during weighing, thereby eliminating the error in the weighing result caused by the difference in the weight of the packaging bottles.

[0016] In a preferred example, the present application may be further configured as follows: before generating a defective product rejection instruction for the unqualified product according to the product weighing result to control the rejection device to reject the corresponding product and obtaining the product identification code of the rejected product as the identification code to be identified, generating the product identification code includes: Acquire product category information, acquire an identification code string according to the product category information, and acquire a weight check start instruction according to the product category information; Obtain a preset product loading sequence, and obtain a corresponding injection head identifier according to the product loading sequence; The character string adding position is acquired according to the injection head identification, and the injection head identification is added to the identification code character string according to the character string adding position to obtain the product identification code.

[0017] By adopting the above technical scheme, since there will be multiple filling heads filling at the same time in the product filling production line, the products will be gathered on the product transportation device after the filling is completed. Therefore, the number of product transportation devices will be less than the number of filling production lines. By obtaining the product loading sequence, the filling heads corresponding to the products gathered on the filling production line can be obtained according to the sequence, thereby facilitating the attachment of the filling head identification to the product identification code; and since the product identification code is usually only used to identify product information during subsequent use, the filling head identification is attached to a specific position, i.e., the character string adding position, without affecting the identification of the product information, so that the obtained product identification code can carry the filling head identification without affecting the subsequent identification and use.

[0018] In a preferred example, the present application can be further configured as follows: parsing the identification code identification information to obtain an abnormal injection head identification, specifically including: According to the string adding position, obtaining the string to be parsed from the identification code identification information; The character string to be parsed is parsed to obtain the abnormal injection head identifier.

[0019] By adopting the above technical solution, the character string recorded in the injection head identification in the identification code identification information can be quickly intercepted through the character string adding position, so that the abnormal injection head identification can be analyzed.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing a weighing device, during the product weight check, it is possible to directly determine whether the amount of liquid concerned by the filling head is qualified according to the weight of the product, so that the amount of weight deviation in the unqualified product can be obtained more directly. At the same time, the weighing method is not affected by the deformation of the bottle body of the packaging bottle and the thickness of the bottle body; further, the identification device is provided, and the information of the filling head can be carried on the identification code sprayed on the product. After the weight abnormality is detected, the abnormal filling head can be quickly located by scanning the identification code, thereby improving the accuracy of liquid level detection, and it is also convenient to quickly locate the abnormal filling head, and then facilitate corresponding maintenance; 2. After weighing, the product weighing information is obtained, and unqualified products are eliminated according to the compared product weighing results.

In the production process of packaging bottles, even if the product passes the inspection, there will be a certain error in its weight. Therefore, taking the average weight of the packaging as the standard weight of the packaging can take the average weight of the packaging bottles as the benchmark, and use the packaging weight range as the error range during weighing, so as to eliminate the error in the weighing result caused by the difference in the weight of the packaging bottles; 4. Since there will be multiple filling heads filling at the same time in the product filling production line, and the products will be gathered on the product transportation device after the filling is completed, the number of product transportation devices will be less than the number of filling production lines. By obtaining the product loading sequence, the filling heads corresponding to the products gathered on the filling production line can be obtained according to the sequence, so as to facilitate the attachment of the filling head identification to the product identification code; and since the product identification code is usually only used to identify product information during subsequent use, the filling head identification is attached to a specific position, that is, the character string addition position, without affecting the identification of the product information, so that the obtained product identification code can carry the filling head identification without affecting the subsequent identification and use.

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figure 1 The present embodiment discloses a liquid product identification detection and weighting device, comprising a product transport device, an identification device 2, a coding detection device 3, a weighing device 4 and a rejection device 5. The product transport device is used to continuously transport liquid products; the identification device 2 is arranged above the product transport device, and comprises a nozzle and a visual detection device, and the visual detection device is used to detect the product position and guide the nozzle to spray the identification code carrying the product identification and the filling port identification at the correct position; the coding detection device 3 is arranged behind the identification device 2, and is used to detect the integrity of the identification code; the weighing device 4 is arranged behind the coding detection device 3, and is used to detect the weight of the product; the rejection device 5 is arranged behind the weighing device 4, and comprises a conveying belt and a cylinder, and the movement direction of the conveying belt is consistent with the conveying direction of the product transport device, so that the product can be fed, and the cylinder is arranged on one side of the conveying belt, and the pushing direction of the cylinder is perpendicular to the conveying direction of the conveying belt, so that the product with unqualified weight is automatically rejected from the conveying belt. In the present embodiment, the identification device 2 can be a device such as coding, laser coding or laser marking that can mark the corresponding identification code on the product packaging.

[0029] The implementation principle of a liquid product identification detection and weighing device in an embodiment of the present application is as follows: the product transportation device continuously transports the liquid product, the visual inspection device detects the product position and guides the nozzle to spray the identification code, the code spraying detection device 3 detects the integrity of the identification code, and the weighing device 4 detects the product weight. If the weight is unqualified, the unqualified product is pushed by the cylinder, so that the unqualified product on the transport belt deviates from the original trajectory and is removed.

[0030] In one embodiment, if Figure 2 As shown, the present application discloses a weight checking method applied to the above device, which specifically includes the following steps: S10: Obtain product weighing information, compare the product weighing information with a preset product weight standard, and obtain a product weighing result, wherein the product weighing result includes a qualified weighing and an unqualified weighing.

[0031] In this embodiment, the product weighing information refers to the weight information obtained by weighing the product by a weighing device. The product weight standard refers to the standard weight of the product after being poured into the package.

[0032] Specifically, the standard weight of the product is obtained in advance, that is, the weight of the liquid in each product is determined, and then together with the weight of the packaging bottle, the standard weight of the product is obtained. After the product is sprayed with the identification code by the identification device, the product is transported to the weighing device by the product transportation device, and the weighed weight is used as the product weighing information. After the product weighing information is obtained, the product weighing information is compared with the product weight standard to determine whether the weight of the product meets the standard, and the judgment result is used as the product weighing result, wherein, if the product weighing information is compared with the product weight standard, the difference is within the error range, then the product weighing result is qualified weighing, if the product weighing information is compared with the product weight standard, the difference is within the error range, it means that the product is poured too much or too little, and the product weighing result includes unqualified weighing.

[0033] S20: Generate a defective product rejection instruction for unqualified products according to the product weighing result, control the rejection device to reject the corresponding products, and obtain the product identification code of the rejected product as the identification code to be identified.

[0034] In this embodiment, the defective product rejection instruction refers to an instruction for controlling the rejection device to reject the products that fail to meet the weight requirements. The product identification code refers to an identification code used to record product information and filling head information.

[0035] Specifically, if the weighing result of the product is unqualified after comparison, a defective product rejection instruction is triggered to the rejection device, and when the unqualified product is transported to the cylinder of the rejection device, the cylinder is controlled to withdraw the product from the conveyor belt for rejection. Furthermore, after rejection, the product identification code of the rejected product is used as the identification code to be identified.

[0036] S30: counting the identification codes to be identified according to a predetermined time period, and identifying the identification codes to be identified to obtain identification code identification information.

[0037] Specifically, within a predetermined time period, that is, after a certain number of unqualified products are collected, the identification codes of all unqualified products are identified, and the identification codes in barcodes, QR codes or other forms are converted into computer-readable strings as the identification code identification information.

[0038] S40: parsing the identification code identification information to obtain an abnormal injection head identifier, and triggering an injection head maintenance message according to the abnormal injection head identifier.

[0039] Specifically, each identification code identification information is parsed, and the position used to distinguish each injection head identification is obtained in the identification code identification information, so as to obtain the abnormal injection head identification. After all the identification code identification information is parsed, the injection head maintenance message is triggered according to the abnormal injection head identification obtained to notify relevant personnel to repair the abnormal injection head.

[0040] In this embodiment, after weighing, the product weighing information is obtained, and unqualified products are eliminated based on the compared product weighing results. At the same time, after counting a certain amount of unqualified products, the product identification codes are centrally identified, so that the identification of the abnormal filling head can be parsed, and then the unqualified products can be quickly obtained while the abnormal filling head can be located, which is convenient for subsequent maintenance.

[0041] In one embodiment, if Figure 3 As shown, in step S10, the product weighing information is obtained, and the product weighing information is compared with the preset product weight standard to obtain the product weighing result, wherein the product weighing result includes qualified weighing and unqualified weighing, specifically including: S11: Obtain product packaging weight information, and obtain the average packaging weight and packaging weight range according to the product packaging weight information.

[0042] In this embodiment, the product packaging weight information refers to the weight of the packaging used to contain the product.

[0043] Specifically, after the production of the packaging for the product, such as a glass bottle, the packaging bottle is weighed to obtain the product packaging weight information of each packaging bottle. Furthermore, all the product packaging weight information is counted, and the value between the largest and smallest weights is taken as the packaging weight interval, and the average value of the product packaging weight information is obtained as the average packaging weight.

[0044] S12: Taking the average package weight as the standard package weight, and obtaining product volume data.

[0045] Specifically, the average weight of the package is used as the standard weight of the package bottle, that is, as the weight of the package bottle set when weighing the product. Further, the capacity of the product to be packed in the package bottle is obtained from the product specification as the product volume data.

[0046] S13: Generate a product weight standard according to the packaging standard weight and product volume data, and use the packaging weight interval as a comparison error interval, and compare the product weighing information according to the product weight standard and the comparison error interval.

[0047] Specifically, when the product is produced, the density of the liquid product is obtained, and the weight in each packaging bottle is obtained based on the density and product volume data, and combined with the packaging standard weight, the product weight standard is obtained.

[0048] Furthermore, the packaging weight interval is used as a comparison error interval during weighing. When the product weight standard is compared with the product weighing information, if the difference is within the comparison error interval, the weighing is deemed to be qualified. If the difference is greater than or less than the comparison error interval, it means that the product was poured in too much or insufficient amount, and the product weighing result includes unqualified weighing.

[0049] In one embodiment, if Figure 4 As shown, before step S20, generating a product identification code includes: S201: Acquire product category information, acquire an identification code string according to the product category information, and acquire a weight check start instruction according to the product category information.

[0050] Specifically, the type of the product currently being checked, such as the manufacturer, product type and specification, is obtained as the product type information. Further, the product type information is generated into a corresponding string to obtain an identification code string, and the product type information can be obtained by parsing the identification code string.

[0051] S202: Obtain a preset product loading sequence, and obtain a corresponding injection head identifier according to the product loading sequence.

[0052] Specifically, since the number of production lines for filling products is usually greater than the number of production lines for weight checking, in order to be able to orderly gather products on different filling production lines onto the same weight checking production line, the product loading sequence is pre-set. Thus, when the weight checking start instruction corresponding to the product type information is obtained, the corresponding filling production line can be obtained in the product loading sequence through the order of inkjet coding, and then the corresponding filling head is obtained according to the located filling production line, thereby obtaining the identification of the filling head that fills the product, that is, the filling head identification.

[0053] S203: Obtain a character string adding position according to the injection head identifier, and add the injection head identifier to the identification code character string according to the character string adding position to obtain a product identification code.

[0054] Specifically, after converting each filling head identification into a corresponding character string, the specific position for adding the character string is obtained in the identification code string, that is, in the identification code string, the character string for recording the product type information is obtained, thereby obtaining the position of the remaining character string in the identification code string, and selecting any position as the string adding position. According to the string adding position, the character string corresponding to the filling head identification is added to the identification code string, thereby obtaining the product identification code, so that the product identification code can normally identify the product type information while also identifying the filling head identification.

[0055] In one embodiment, if Figure 5 As shown, in step S30, the identification code identification information is parsed to obtain the abnormal injection head identification, which specifically includes: S31: According to the position where the string is added, the string to be parsed is obtained from the identification code identification information.

[0056] Specifically, when the identification code identification information is identified, the corresponding character string is intercepted from the identification code identification information according to the character string addition position and the character string length corresponding to the injection head mark as the character string to be parsed.

[0057] S32: Parse the character string to be parsed to obtain an abnormal injection header identifier.

[0058] Specifically, the character string to be parsed is identified and parsed, so as to obtain a corresponding injection head identifier, that is, to obtain the abnormal injection head identifier.

[0059] In one embodiment, if Figure 6 As shown, in step S40, triggering a filling head maintenance message according to the abnormal filling head identification specifically includes: S41: Obtaining unqualified type information from unqualified weighing, wherein the unqualified type information includes overweight and underweight.

[0060] Specifically, among the corresponding product weighing results of all rejected products, the ones with the same abnormal filling head identification are counted to obtain the unqualified type information of the abnormal filling head, that is, the situation in which the abnormal filling head is overweight and / or the filling amount is insufficient.

[0061] S42: triggering a corresponding injection head maintenance message according to the unqualified type information.

[0062] Specifically, according to the unqualified type corresponding to each abnormal injection head and the corresponding quantity of each type, it is identified from the pre-trained abnormality recognition model to obtain the attribution analysis data of the abnormality, and the corresponding injection head maintenance message is triggered according to the attribution analysis data.
