Description

Technical Field

[0001] This invention relates to the field of cardboard box production, and in particular to an environmentally friendly cardboard box production line logistics tracking system. Background Technology

[0002] With the rapid development of my country's e-commerce industry, the amount of express packaging waste has increased rapidly, leading to an increased demand for environmentally friendly cardboard boxes to reduce packaging waste.

[0003] The prior art patent publication number CN104015398A discloses a carton production line, including a watermarking machine and a gluing machine. A first conveyor line and a second conveyor line are arranged between the watermarking machine and the gluing machine. A flipping trolley is arranged between the first conveyor line and the second conveyor line to flip the carton boards on the first conveyor line up and down onto the second conveyor line. A lifting device corresponding to the flipping trolley is also arranged at the end of the first conveyor line. At the end of the second conveyor line, a lifting device for raising the carton boards, an alignment device II for aligning the carton boards, and a pushing device for pushing the carton boards toward the gluing machine are arranged. The pushing plate of the pushing device can be folded.

[0004] However, the above invention has the following problems: During the production process of environmentally friendly cardboard boxes, due to long-term use of equipment or other sudden abnormal conditions, such as sudden vibration of equipment, but production resumes after a period of time, the error may not be corrected in time during the cardboard box manufacturing process, which will lead to a decrease in the quality of cardboard box production. At this time, it is necessary to track the production process of environmentally friendly cardboard boxes. Therefore, this application proposes an environmentally friendly cardboard box production line logistics tracking system. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing an environmentally friendly cardboard box production line logistics tracking system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly cardboard box production line logistics tracking system includes a production information marking module, a production data detection module, a tracking information analysis module, an abnormal object detection module, and a production information output module.

[0008] The production information marking module is used to mark the cartons in the production process, set the production threshold, count the number of cartons processed by a single machine according to the production time sequence, mark the cartons as a group when the count reaches the production threshold, and start counting again. Then, the count values ​​of the group numbers are combined to generate a carton number, and the carton number is used as marking information and transmitted to the production data detection module.

[0009] The production data detection module collects processing data from the equipment during the carton production process based on the tagging information, generates detection information, and transmits it to the tracking information analysis module.

[0010] The tracking information analysis module, based on the detection information, combines the detection information with the corresponding standard data to obtain the production difference. The production difference is compared with the equipment preset difference to obtain the production signal, which includes processing signal and abnormal signal. Then, the tracking information analysis module transmits the production signal to the production information output module.

[0011] The abnormal object detection module detects the carton corresponding to the abnormal signal in the production signal and generates a missing signal. When a missing signal is detected, the code is skipped. After production is completed, the final code of all equipment is checked, the code consistency is judged, and a code abnormality signal is generated and transmitted to the production information output module.

[0012] The production information output module is used to output production signals and coded abnormality signals.

[0013] As a further aspect of the present invention, the method for obtaining the marking information is as follows:

[0014] First, label the cardboard box production equipment according to the processing sequence as i, i = 1, 2, ..., I, where I represents the total number of equipment;

[0015] When i is 1, the corresponding device is marked as the first device. When the first device processes the first carton, a start signal is generated, and the subsequent devices are started.

[0016] Set a production threshold N, and mark the processed cartons as n according to the production time sequence, n = 1, 2, ... When n = N, mark these N cartons as a group, and n starts counting again. Continue in this way to obtain group A of data, and mark each carton number as An.

[0017] As a further aspect of the present invention, the specific method for generating the start signal is as follows:

[0018] In the automated production line for cardboard box production, all equipment is equipped with both manual and automatic start / stop modes. The operator first starts the first equipment, which is in an idle state. When the first equipment begins processing cardboard boxes, it switches from an idle state to a running state. When the first equipment is in a running state, a start signal is generated, which automatically starts the subsequent equipment. The idle state means that the equipment is running without load, that is, it is not processing cardboard boxes. The running state means that the first equipment is running under load, that is, it is currently processing cardboard boxes.

[0019] As a further aspect of the present invention, the standard data is acquired by the production information acquisition module and transmitted to the tracking information analysis module. The standard data refers to the weight of the carton during the carton production process, the dimensions of each position, and the carton transportation positioning and printing positioning.

[0020] As a further aspect of the present invention, the method for acquiring production signals is as follows:

[0021] Choose any carton as the analysis object Ac, c∈n, obtain the standard data Bi of the analysis object Ac when it is processed by the first device, and at the same time obtain the detection data Di of the standard data Bi corresponding to the analysis object Ac, where i represents the corresponding device;

[0022] Subtracting Bi from Di yields the production difference Si, which is positive. The production difference Si is compared with the equipment's preset difference Yi. If Si ≤ Yi, a processing signal is generated; otherwise, if Si > Yi, an abnormal signal is generated. When an abnormal signal is generated, the corresponding production equipment is marked.

[0023] All coded cartons are treated as analysis objects and processed on each processing equipment to obtain production signals. When the analysis object is completed and its production signals are all processing signals, the analysis object is marked as a qualified product. If the analysis object contains abnormal signals in its production signals during logistics operation, the product is marked as a non-qualified product.

[0024] As a further aspect of the present invention, the method for obtaining the encoded abnormal signal is as follows:

[0025] Based on the abnormal signal, the analysis object corresponding to the abnormal signal is detected. At this time, the subsequent equipment generates a missing signal for the detected analysis object. When a missing signal is generated, the subsequent equipment automatically jumps to the next code of the analysis object. When this production is completed, the final code of each equipment is obtained. When the codes are consistent, the equipment is in a normal state of material tracking. When the code of one equipment is inconsistent with the codes of other equipment, a code abnormality signal is generated and transmitted to the production information output module.

[0026] As a further aspect of the present invention, it also includes an equipment maintenance analysis module. This module is used to analyze the maintenance status of the equipment based on coded abnormality signals and production signals. The specific analysis method is as follows:

[0027] Based on the working time of the equipment on the day, each piece of equipment is taken as the target equipment, and the number of times the target equipment is marked (Bi), the actual number of times it is operated on the day (Yi), and the theoretical number of times it is operated (Li) are obtained, where i represents the equipment.

[0028] Based on formula The equipment failure coefficient Gi is obtained, where K takes the value of 0 or 1. When the target equipment generates an coded abnormal signal, K takes the value of 1, and otherwise K takes the value of 0. α1, α2 and α3 are threshold coefficients, respectively.

[0029] Set a fault threshold Gyi, compare the equipment fault coefficient Gi with the fault threshold Gyi. If Gi≤Gyi, no processing will be performed. If Gi>Gyi, an extreme coefficient J will be set and incremented by one, i.e. J=J+1, with J initially set to 0.

[0030] Based on formula The operation and maintenance coefficient W is obtained. When the operation and maintenance coefficient W≥X1, a comprehensive operation and maintenance signal is generated and transmitted to the production information output module. Otherwise, if the operation and maintenance coefficient W<X1, the production line continues to operate.

[0031] As a further aspect of the present invention: the method for obtaining the fault threshold Gyi is as follows:

[0032] The fault coefficient of each device in the automated production line during its initial operating time is obtained, and the average fault coefficient of each device during its initial operating time is averaged to obtain the fault mean Gai. The value obtained by multiplying the fault mean Gai of the device during its initial operating time by b1 is used as the fault threshold Gyi, where b1 is the proportional coefficient.

[0033] Compared with existing technologies, the advantages of this environmentally friendly cardboard box production line logistics tracking system are:

[0034] 1. This invention assigns a number to each cardboard box during production, allowing each piece of equipment to process and monitor the boxes according to their assigned number. This enables real-time monitoring of the flow and production information of the cardboard boxes, providing a better understanding of the production status of environmentally friendly cardboard boxes in automated production lines. It also reduces the need for manual inspections by workers during the processing of environmentally friendly cardboard boxes, increases the automation level of the equipment, and improves the quality of environmentally friendly cardboard box production.

[0035] 2. The present invention generates a start signal based on the operating status of the first device and transmits it to the subsequent devices to automatically start the subsequent devices. On the one hand, this reduces the number of operation steps for equipment management personnel. On the other hand, it reduces equipment energy consumption by automatically starting the subsequent devices when the first device is in actual operation.

[0036] 3. This invention obtains the maintenance status of equipment based on coded abnormal signals and production signals. When the maintenance coefficient of the production line is greater than or equal to X1, a comprehensive maintenance signal is generated to remind external personnel to perform overall maintenance on the equipment. By tracking the logistics during carton production, the maintenance status of the production line is judged to ensure the efficiency and quality of the production line operation. Attached Figure Description

[0037] Figure 1 This is a schematic diagram of a module of an environmentally friendly cardboard box production line logistics tracking system proposed in this invention. Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Example 1: Refer to Figure 1 An environmentally friendly cardboard box production line logistics tracking system includes a production information collection module, a production information marking module, a production data detection module, a tracking information analysis module, and a production information output module.

[0040] The production information acquisition module is based on the production process of environmentally friendly cardboard boxes. It acquires standard data during the production process and transmits the standard data from the production information acquisition module to the tracking information analysis module. The standard data refers to the data required during the cardboard box production process. Specifically, the standard data includes the weight of the cardboard box during production, the dimensions of each position, and the cardboard box transportation positioning and printing positioning. Specifically, the cardboard box transportation positioning refers to the fixed position of the semi-finished product of the cardboard box when it is running on the production line during the manufacturing process, and the printing positioning refers to the precise position of the printed pattern on the cardboard box. It should be further noted that all the cardboard boxes described here are environmentally friendly cardboard boxes.

[0041] The production information marking module tracks the material flow status during the processing of the same environmentally friendly cardboard box by marking the cardboard boxes processed by the equipment in production operation. The specific marking method is as follows:

[0042] S1: According to the processing sequence and corresponding processing equipment in the carton production process, the processing equipment is first marked as i according to the production line running direction, i = 1, 2, ..., I, indicating that there are I production equipment on the automated production line of carton production. It should be further explained that each processing equipment corresponds to one processing step in the carton production process. All processing equipment work together to form a complete automated production process on the carton production line.

[0043] S2: First, set i to 1 and mark the corresponding device as the first device. Use the first carton processed by the first device as the running flag of the automated production line, generate a start signal, transmit the start signal to the subsequent devices of the automated production line, and start the devices.

[0044] It should be further explained that in this embodiment, in the automated production line for carton production, all equipment has manual start-stop and automatic start-stop capabilities. When the equipment administrator manually starts the first equipment, only the first equipment starts in the automated production line. When the first equipment starts, it will have an idle running state and a running state. The idle running state means that the equipment is running without load, that is, it is not processing cartons. The running state means that the first equipment is running under load, that is, it is currently processing cartons. When the first equipment detects that it is in the running state, it generates a start signal and automatically starts the equipment behind it in sequence. On the one hand, this reduces the number of operation steps for equipment management personnel. On the other hand, automatically starting the equipment behind it when the first equipment is in the running state reduces equipment energy consumption.

[0045] S3: Set a production threshold N, then mark the number of cartons processed by a single device as n according to the production time sequence, n = 1, 2, ... When n = N, record N cartons as a group, and start counting n again, that is, start marking n from 1 until n = N, and so on, to obtain group A data. It should be further explained that in the process of automating the production line, the group number is combined with the data to obtain the carton number An, so as to mark the cartons in production. An represents the nth carton in group A, and each device in the automated production line will process carton An.

[0046] The production information marking module then uses the carton number as marking information and transmits it to the production data detection module;

[0047] Based on the marking information of carton production, the production data detection module performs real-time detection and collection of processing data of equipment during the carton production process, and generates detection information. At the same time, the production data detection module transmits the detection information to the tracking information analysis module. The specific detection information includes the parameter information corresponding to each production equipment. In this embodiment, the detection information corresponds one-to-one with the standard data.

[0048] The tracking information analysis module performs tracking analysis based on the equipment's standard data, the carton's marking information, and its detection information. The specific tracking analysis method is as follows:

[0049] SS1: Based on the numbering information, select any carton running on the automatic production line as the analysis object Ac, c∈n. In this embodiment, A specifically takes the value 0 and c takes the value 1. At this time, the numbering information of the analysis object is 01.

[0050] SS2: When the object of analysis Ac is processed in the first device, the corresponding standard data in the first device is first obtained and marked as Bi, where i is 1. After the object of analysis is processed in the first device, it is transported to the second device through the automatic transmission device. During the processing in the second device, the object of analysis Ac after processing in the first device needs to be identified and detected to improve the automation level of the device. The data detected here is the processing data of the previous device, that is, the detection data Di in the first device.

[0051] For example, on an automated production line, the first device cuts cardboard boxes. After the cardboard boxes are cut on the first device, they are transported to the second device via a conveyor belt. The second device applies horizontal creases to the cut cardboard boxes. In this case, the second device needs to measure the cut cardboard boxes according to the cutting standards of the first device to determine the position of the horizontal creases. The cutting data detected by the second device is the detection data, while the data set in the first device is the standard data.

[0052] SS3: Subtract Bi from Di to obtain the production difference Si of the first equipment. Here, Si is the absolute value of Di minus Bi. First, compare the production difference Si with the corresponding equipment preset difference Yi. If Si≤Yi, a processing signal is generated, and the second equipment continues to process the analysis object. Conversely, if Si>Yi, an abnormal signal is generated. When an abnormal signal is generated, the corresponding production equipment is marked. The equipment preset difference Yi is set by those skilled in the art according to the actual equipment.

[0053] Similarly, when all the objects under analysis are processed on the automated production line, the above steps SS2 to SS3 are performed to obtain the production signals of the equipment. The production signals include processing signals and abnormal signals.

[0054] SS4: When the analysis object is completed and all its production signals are processing signals, mark the analysis object as a qualified product. If the analysis object contains abnormal signals in its production signals during logistics operation, mark the product as a non-qualified product.

[0055] The tracking information analysis module then transmits the production signal to the production information output module;

[0056] The production information output module displays the production signals based on the production signals and makes them available for viewing by external personnel.

[0057] Example 2: This example is based on Example 1, but differs in that it includes an abnormal object detection module. Based on abnormal signals, the abnormal object detection module detects the analysis object corresponding to the abnormal signal. Subsequent devices then generate a missing signal for the detected analysis object. When a missing signal is generated, the subsequent devices automatically jump to the next device for the analysis object's encoding. After production is completed, the final encoding of each device is obtained. When the encodings match, the device's material tracking is in normal condition. When the encoding of one device is inconsistent with the encodings of other devices, an encoding anomaly signal is generated and transmitted to the production information output module. The production information output module generates an audio-visual alert for the corresponding device and its encoding anomaly signal, which is then displayed for external personnel to view.

[0058] Example 3: This example differs from Examples 1 and 2 in that it further includes an equipment maintenance analysis module. This module analyzes the equipment's maintenance status based on coded abnormal signals and production signals. The specific analysis method is as follows:

[0059] F1: Based on the equipment working time on the day, select one equipment as the target equipment, obtain the number of times the target equipment is marked Bi, and mark the actual number of times the target equipment operates on the day as Yi, and mark the theoretical number of times the target equipment operates as Li. The actual number of times Yi is marked represents the number of cartons actually processed by the target equipment, and the theoretical number of times it operates represents the number of cartons that the target equipment theoretically needs to process. i represents the target equipment i.

[0060] F2: Based on formula The equipment failure coefficient Gi is obtained, where K takes the value 0 or 1. When the target device generates a coded abnormal signal, K takes the value 1. Conversely, when the target device does not generate a coded abnormal signal, K takes the value 0. α1, α2 and α3 are threshold coefficients, respectively.

[0061] F3: Set the fault threshold Gyi. Compare the equipment fault coefficient Gi with the fault threshold Gyi. If Gi ≤ Gyi, no action will be taken. If Gi > Gyi, an extreme coefficient J will be set and incremented by one, i.e., J = J + 1. The initial value of J is 0. The method for setting the fault threshold Gyi is as follows:

[0062] In the automated production line, the fault coefficient of each device during its initial operating time is obtained. The average fault coefficient during the initial operating time is first taken to obtain the fault mean Gai. Then, the value obtained by multiplying the fault mean Gai during the initial operating time by b1 is used as the fault threshold Gyi. In this embodiment, b1 is 0.8. The initial operating time of the device refers to the time when the device in the automated production line of environmentally friendly cardboard boxes is first installed and put into production. The specific initial operating time is set to 10 days, and the fault mean is the average fault coefficient within 10 days.

[0063] F4: Based on formula The operation and maintenance coefficient W is obtained. When the operation and maintenance coefficient W≥X1, a comprehensive operation and maintenance signal is generated and transmitted to the production information output module to remind external staff to perform overall maintenance on the equipment. Then, by tracking the logistics during carton production, the operation and maintenance status of the overall equipment on the production line is judged to ensure the efficiency and quality of the overall equipment operation on the production line. Conversely, if the operation and maintenance coefficient W<X1, the production line continues to operate. X1 is a threshold, and its specific value is set by those skilled in the art.

[0064] Example 4: This example is based on Example 1, Example 2 and Example 3, and is used to integrate and implement Example 1, Example 2 and Example 3.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
