Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent packaging production line, and particularly relates to an intelligent packaging production line with high accuracy and a counting control method thereof. BACKGROUND

[0002] Due to the increasing packaging demand of granular, flaky, capsule, toy building blocks and other materials, intelligent packaging production lines are currently used in the market to package materials. The existing intelligent packaging production line generally comprises a circulating line body, a lifting machine and a packaging machine located at the end of the circulating line body, a plurality of feeding single machines placed on both sides of the circulating line body, and a plurality of storage hoppers placed on the conveying belt of the circulating line body. The storage hoppers rotate with the conveying belt to collect the materials discharged from the feeding single machines. After the storage hoppers collect the materials, they are lifted by the lifting machine and the materials are poured into the packaging machine for packaging, and finally the finished product packages are produced.

[0003] However, in the actual production process, sometimes there are situations of material leakage, material excess, and inconsistency between the types of materials and actual demand, which are caused by the following reasons. First, the material sticking phenomenon occurs due to static electricity between the material and the discharging paddle of the feeding single machine. Second, the material bounces out of the storage hopper due to collision after being discharged from the feeding single machine into the storage hopper. Third, the material adheres to the storage hopper when pouring the material into the packaging machine due to static electricity between the storage hopper and the material. SUMMARY

[0021] Furthermore, the counting control method also includes establishing a material bag barcode system in the packaging machine. The material bag barcode system reads the barcodes on the material bags and converts them into digital signals, which are then transmitted to the main control system. When materials from the same batch are stored in the hopper... or If the quantity analysis relationship is not satisfied, the main control system determines and summarizes the specific missing or extra material types and corresponding quantities during the material conveying process and the material unloading process of the storage hopper, and links the summarized information to the barcode of the corresponding material package.

[0022] Furthermore, the counting control method also includes manually scanning the barcodes of non-finished material packages with a barcode scanner and supplementing the material type and quantity based on the information retrieved.

[0023] Furthermore, after sorting out finished product packages and non-finished product packages, the main control system will clear the material analysis results corresponding to the batch information of the storage hopper.

[0024] Compared with the prior art, the present invention has the following advantages:

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] As Figures 2 to 8The application provides a high-accuracy intelligent packaging production line, which comprises a circulating line body 1, an elevator 2, a packaging machine 3, a plurality of feeding single machines 4 and a plurality of storage hoppers 5. In the embodiment, the feeding single machines can be feeding single machines of vibrating discs or feeding single machines of elevators. Figure 2 As shown in the figure, the plurality of feeding single machines 4 are located on both sides of the circulating line body 1, and the plurality of storage hoppers 5 are conveyed on the circulating line body 1 to sequentially receive materials discharged from the plurality of feeding single machines 4. The elevator 2 and the packaging machine 3 are located at the end of the circulating line body 1. Figure 4 As shown in the figure, when the storage hopper 5 is conveyed to the end of the circulating line body 1, the elevator 2 drives the storage hopper 5 to be lifted upward, the packaging machine 3 is located below the top of the elevator 2, and the storage hopper 5 is driven by the elevator 2 to pour materials to the packaging machine 3 at the top of the elevator 2. The packaging machine 3 packages the materials into material packages, and then the storage hopper 5 rotates to the circulating line body 1 for the next cycle. The plurality of storage hoppers 5 operate in this way to batch output material packages.

[0041] As shown in the figures, Figure 3 and Figure 4 The intelligent packaging production line further comprises a discharging visual detection mechanism 6 and a pouring visual detection mechanism 7. The feeding single machine 4 comprises a discharging mechanism 41, the feeding inlet of the discharging mechanism 41 is provided with a counting sensor 42 to count the materials entering the discharging mechanism 41 and transmit information to the industrial control system of the feeding single machine 4. The discharging outlet of the discharging mechanism 41 is provided with a anti-jumping limiting frame 43, and the discharging visual detection mechanism 6 is arranged on the anti-jumping limiting frame 43. The discharging visual detection mechanism 6 can capture and process images of the materials falling into the storage hopper 5 through the anti-jumping limiting frame 43 and transmit information to the industrial control system of the feeding single machine 4.

[0042] As shown in the figures, Figure 2 and Figure 3 The circulating line body 1 is provided with a plurality of rotating block hoppers 8, which are located below the anti-jumping limiting frame 43, that is, each feeding single machine 4 is provided with a rotating block hopper 8, and the rotating block hopper 8 positions the storage hopper 5 to align the anti-jumping limiting frame 43 with the storage hopper 5. Specifically, the storage hopper 5 is conveyed on the circulating line body 1, and when the first rotating block hopper 8 detects the storage hopper 5, the storage hopper 5 is blocked from conveying forward. At this time, the anti-jumping limiting frame 43 of the discharging mechanism 41 of the feeding single machine 4 is aligned with the storage hopper 5. After the feeding single machine 4 discharges materials, the first rotating block hopper 8 releases the storage hopper 5 to continue conveying to the next feeding single machine 4. Each rotating block hopper 8 can operate on each storage hopper 5 in this way to ensure the accuracy of material discharge of each feeding single machine 4.

[0043] As shown in the figures, Figure 4As shown, a hopper 31 is provided between the top of the packaging machine 3 and the elevator 2. A material discharge vision detection mechanism 7 is installed on the hopper 31. The material discharge vision detection mechanism 7 can capture and process images of the material passing through during the discharge process and transmit the information to the main control system.

[0044] The packaging machine has a sorting device below the three-seal bag opening. The sorting device can sort non-finished material bags and finished material bags to ensure the accuracy of the output material bags.

[0045] Furthermore, such as Figure 5 As shown, the material unloading visual inspection mechanism 6 includes a first camera 61 and a first light source 62. The first camera 61 and the first light source 62 are located on both sides of the anti-jump limit frame 43. Light-absorbing material is adhered around the anti-jump limit frame 43. The light-absorbing material can absorb the light emitted by the first light source 62, so that the material and the surrounding environment form a dark contrast, which improves the imaging effect of the material captured by the first camera 61, thereby improving the accuracy of visual inspection.

[0046] Furthermore, such as Figure 8 As shown, the material pouring visual inspection mechanism 7 includes a second camera 71, a second light source 72, and a transition structure 73. In this embodiment, the transition structure 73 is a transition material distribution plate, which is inclinedly arranged on one side of the pouring hopper 31. The discharge port 74 formed by the transition material distribution plate and the other side wall of the pouring hopper 31 is connected to the discharge port of the pouring hopper 31. The second camera 71 and the second light source 72 are located between the discharge port 74 and the discharge port. When the storage hopper 5 rotates to pour material, the material first falls onto the transition material distribution plate to disperse the material. Then, the material falls along the slope into the discharge port 74 and falls from the discharge port of the pouring hopper 31 into the packaging machine 3 for packaging. During this process, the second camera 71 captures and processes images of the material passing by and transmits the information to the main control system.

[0047] Furthermore, the sorting device includes a sorting cavity, a rotating mechanism, a waste discharge channel, and a finished product channel. The rotating mechanism can connect the sorting cavity with the waste discharge channel or with the finished product channel. Specifically, in this embodiment, the rotating mechanism is a chain plate conveying mechanism, which includes a chain plate with partitions. The sorting cavity is located between two adjacent partitions. Rotating the chain plate to one side of the chain plate conveying mechanism can connect the sorting cavity with the waste discharge channel, and rotating the chain plate to the other side of the chain plate conveying mechanism can connect the sorting cavity with the finished product channel.

[0048] Furthermore, such as Figure 6 As shown, the rotating baffle 8 includes a rotating driver 81, a rotating baffle 82, and a rotating bracket 83. The rotating driver 81 is fixed on the circulation line 1 through the rotating bracket 83, and the driving end of the rotating driver 81 is drivenly connected to the rotating baffle 82.

[0049] like Figure 1As shown, the present application also provides a counting control method of the above intelligent packaging production line, which comprises the following steps:

[0050] S1: Each feeding unit 4 obtains the material type X i (i=1, 2, …, n) information, and manually pours the material of the corresponding type of each feeding unit 4 into the feeding unit 4. When the material enters the discharging mechanism 41, the counting sensor 42 on each feeding unit 4 counts it to determine the number N of each type of material entering the discharging mechanism 41 i (i=1, 2, …, n).

[0051] S2: The industrial control system of each feeding unit 4 outputs a material discharging command. The discharging visual detection mechanism 6 captures the material image dropped into the storage hopper 5 through the anti-jumping limiting frame 43, identifies the material type Y discharged by each feeding unit 4 through algorithm, and counts the number M of each type of material passing through the discharging visual detection mechanism 6 i (i=1, 2, …, n). i (i=1, 2, …, n); the industrial control system of each feeding unit 4 analyzes the two groups of data X i and Y i , M i and N i in real time, and transmits the analysis information to the main control system of the packaging production line.

[0052] S3: After the storage hopper 5 receives multiple feeding units, it is lifted at the end of the circulating line body 1 by the elevator 2, and finally realizes material pouring and packaging at the pouring hopper 31. The pouring visual detection mechanism 7 captures the material image passing through during the pouring process, identifies the total material type K through algorithm, and counts the total material quantity Q. The main control system of the packaging production line analyzes the sum of Q and M i of the same storage hopper 5, and the quantity analysis relationship is as follows:

[0053]

[0054] S4: The rotating baffle hopper 8 and the packaging machine 3 of each feeding unit 4 establish a storage hopper batch tracking system. During the conveying process of the packaging production line, the rotating baffle hopper 8 and the packaging machine 3 detect the storage hopper 5 through the storage hopper batch tracking system, record the batch information of the storage hopper 5 in real time, and transmit the batch information to the main control system, so as to ensure that the batch information of the same storage hopper 5 can be traced throughout the packaging production line.

[0055] S5: During the operation of the packaging production line, the main control system records the material conditions of the storage hopper 5 receiving all batch information throughout the packaging production line, and combines the analysis: if all Y i =X i(i = 1, 2, …, n) and all M i = N i (i = 1, 2, …, n) and satisfy the quantity analysis relationship, when all three are satisfied, the material package output from the storage hopper 5 of this batch information will be considered to meet the requirements of the finished product material package, and the main control system will control the sorting device to rotate the material package to the finished product channel to output the finished product material package; if the storage hopper 5 of the same batch information, or or does not satisfy the quantity analysis relationship, that is, there is a material type Y i and X i of one of the material supply machines 4 does not match or the material quantity M i and N i of one of the material supply machines 4 is not equal, or does not satisfy the quantity analysis relationship, as long as one of the three conditions is met, the material package output from the storage hopper 5 of this batch information will be considered to not meet the requirements of the finished product material package, and the main control system will control the sorting device to rotate the corresponding material package to the impurity removal channel to complete the impurity removal of the non-finished product material package.

[0056] Further, in the present embodiment, the way for each material supply machine 4 in S1 to obtain the material type X i information is to establish a material ERP system, the main control system communicates with the material ERP system, and the main control system realizes the collection and storage of the material type X i information by extracting the material type X i information from the material BOM table derived from the material ERP system, and finally distributes the information to each material supply machine 4.

[0057] In other embodiments, the way for each material supply machine 4 in S1 to obtain the material type X i information is that the main control system can generate the material type X i information BOM table by scanning and collecting material images and processing and analyzing, and distribute the information to each material supply machine 4.

[0058] In other embodiments, the method for each material supply machine 4 in S1 to obtain the material type X i information is to set a feeding visual detection mechanism in front of the feeding inlet of the feeding mechanism 41 of each material supply machine 4, capture material images through each feeding visual detection mechanism, and identify the material type X i information by combining algorithms.

[0059] Furthermore, the batch tracking system for the storage hopper has two modes. When the batch tracking system for the storage hopper detects the storage hopper 5, it activates the blocking mode for the storage hopper 5, that is, the rotary driver 81 drives the rotary stop lever 82 to rotate, so as to block the storage hopper 5 from being conveyed forward. When the industrial control system executes the material release command, the batch tracking system for the storage hopper activates the releasing mode for the storage hopper 5, that is, the rotary driver 81 drives the rotary stop lever 82 to rotate to the initial state, so as to release the storage hopper 5 and allow it to be conveyed forward to the next feeding unit 4.

[0060] Furthermore, the counting control method also includes establishing a material bag barcode system in the packaging machine 3. The material bag barcode system reads the barcodes on the material bags, converts the read information into digital signals, and transmits them to the main control system. When the same batch of information is stored in the hopper 5, or If the quantity analysis relationship is not met, the corresponding feeder single machine 4 industrial control system determines the specific missing or extra material types and corresponding material quantities during the conveying process, and the main control system determines the specific missing or extra material types and corresponding material quantities during the unloading process. Finally, the main control system summarizes the above information and links the summarized information to the barcode of the corresponding material bag. This material bag is identified as a non-finished product material bag.

[0061] In the same batch of information, in hopper 5, all Y i =X i (i=1,2,…,n) and all M i =N i (i=1,2,…,n), and under the condition that the quantity analysis relationship is satisfied, the corresponding feeding unit 4 industrial control system will determine that there is no shortage or excess material during the conveying process, and the main control system will determine that there is no shortage or excess material during the unloading process. Finally, the main control system will link the absence of shortage or excess material to the barcode of the corresponding material bag, and this material bag will be identified as a finished product material bag.

[0062] Furthermore, the counting control method also includes manually scanning the barcode of the non-finished material package with a barcode scanner, reading and querying the information of whether the non-finished material package is missing or has excess material, and supplementing the material type and quantity according to the output information, that is, supplementing the non-finished material package into a finished material package.

[0063] Furthermore, after sorting out finished product packages and non-finished product packages, the main control system will clear the material analysis results corresponding to the 5 batches of information in the storage hopper, so as to avoid the overlap of the material analysis results corresponding to the 5 batches of information in the storage hopper in the next cycle and the previous cycle, thereby further improving the accuracy of the data.

[0064] In summary, in this invention, the material type X obtained by each feeding machine 4 is controlled by the industrial control system of each feeding machine 4. i The material type Y is captured and identified by each of the 6 visual inspection units for material feeding.i This first set of data, along with the counting sensor 42 determining the quantity N of each type of material entering the feeding mechanism 41, i And the quantity M of each type of material passing through the visual inspection mechanism 6. i This second set of data is analyzed to determine whether all values ​​are equal, and the total quantity Q and M of materials passing through the material unloading process are captured by the main control system's visual inspection mechanism 7 during the unloading process. i The system analyzes and judges whether the sums are equal, and through double comparison analysis, it greatly improves the accuracy of the quantity and type of materials in the finished product packages. Secondly, each feeding machine 4 rotating hopper 8 and packaging machine 3 establishes a batch tracking system for the storage hoppers, ensuring that the same batch of storage hoppers 5 in the packaging production line is traceable throughout the process. This allows for accurate determination of whether the material package output by storage hopper 5 for a certain batch is a finished product package or a non-finished product package, improving the accuracy of the information. In addition, a sorting device is installed below the sealing opening of the packaging machine 3 to exclude non-finished product packages, further ensuring the accuracy of finished product packages. Finally, after sorting out finished product packages and non-finished product packages, the main control system will clear the material analysis results corresponding to the batch information of storage hopper 5, avoiding overlap between the material analysis results of storage hopper 5 in the next cycle and the previous cycle, further improving the accuracy of the data.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
