Description

Technical Field

[0001] This utility model relates to the field of intelligent packaging production line technology, specifically to an intelligent packaging production line with high accuracy. Background Technology

[0002] With the increasing demand for packaging materials such as granules, flakes, capsules, and toy building blocks, intelligent packaging production lines are now widely used in the market. Existing intelligent packaging production lines generally include a circulating line and an elevator and packaging machine located at the end of the circulation. Multiple feeding machines are placed on both sides of the circulating line, and multiple storage hoppers are placed on the conveyor belt of the circulating line. The storage hoppers rotate with the conveyor belt to collect the materials released by the multiple feeding machines. After the storage hoppers have collected enough materials, they are lifted by the elevator and poured into the packaging machine for packaging, finally producing finished product packages.

[0003] However, in actual production, sometimes material leakage, excess material, and discrepancies between the material type and actual needs occur. This phenomenon is caused by several factors. First, static electricity between the feeding plate of the feeding machine and the material causes material to stick. Second, after the feeding machine lowers the material into the storage hopper, the material bounces out of the storage hopper due to collision. Finally, static electricity between the storage hopper and the material causes the material to adhere to the storage hopper when it is poured into the packaging machine. Utility Model Content

[0004] To address the existing problems, this utility model proposes a highly accurate intelligent packaging production line, which greatly improves the accuracy of the quantity and type of materials in the finished product packaging.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A high-accuracy intelligent packaging production line includes a circulating line, an elevator, a packaging machine, multiple feeding units, and multiple storage hoppers. The feeding units, storage hoppers, elevator, and packaging machine are located on both sides, above, and at the end of the circulating line, respectively. The line is characterized by further including a material feeding visual inspection mechanism and a material unloading visual inspection mechanism. Each feeding unit includes a feeding mechanism, the feeding inlet of which is equipped with a counting sensor, and the feeding outlet of which is equipped with an anti-jump limit frame.

[0013] Furthermore, the sorting and conveying device includes a sorting chamber, a rotating mechanism, a waste discharge channel, and a finished product channel. The rotating mechanism can connect the sorting chamber to the waste discharge channel or to the finished product channel.

[0014] Furthermore, the rotating bucket includes a rotating driver, a rotating lever, and a rotating bracket. The rotating driver is fixed to the circulation line via the rotating bracket, and the driving end of the rotating driver is driven by the rotating lever.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 7 The diagram shows a high-accuracy intelligent packaging production line provided by this utility model, including a circulating line 1, an elevator 2, a packaging machine 3, multiple feeding units 4, and multiple storage hoppers 5. In this embodiment, the feeding units can be either vibrating disc feeding units or lifting feeding units, such as... Figure 1 As shown, multiple feeding machines 4 are located on both sides of the circulating line 1. Multiple storage hoppers 5 are conveyed on the circulating line 1 to sequentially receive the materials released by the multiple feeding machines 4. The elevator 2 and the packaging machine 3 are both located at the end of the circulating line 1. When the storage hopper 5 is conveyed to the end of the circulating line 1, the elevator 2 will drive the storage hopper 5 to rise. The packaging machine 3 is located below the top of the elevator 2. Driven by the elevator 2, the storage hopper 5 pours material from the top of the elevator 2 to the packaging machine 3. The packaging machine 3 packages the material into material bags. Then the storage hopper 5 returns to the circulating line 1 for the next cycle. Multiple storage hoppers 5 operate in this way, thereby outputting material bags in batches.

[0033] like Figure 2As shown, the intelligent packaging production line also includes a material feeding visual inspection mechanism 6 and a material pouring visual inspection mechanism 7. The feeding unit 4 includes a material feeding mechanism 41. The feeding port of the material feeding mechanism 41 is equipped with a counting sensor 42 to count the material entering the material feeding mechanism 41 and transmit the information to the industrial control system of the feeding unit 4. The feeding port of the material feeding mechanism 41 is equipped with an anti-jump limit frame 43. The material feeding visual inspection mechanism 6 is set on the anti-jump limit frame 43. The material feeding visual inspection mechanism 6 can capture and process images of the material falling into the storage hopper 5 through the anti-jump limit frame 43 and transmit the information to the industrial control system of the feeding unit 4.

[0034] like Figure 3 As 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.

[0035] like Figure 1 and Figure 2 As shown, the circulating production line 1 is equipped with multiple rotating baffles 8, which are located below the anti-jump limit frame 43. That is, each feeding machine 4 is equipped with one rotating baffle 8. The rotating baffle 8 positions the storage hopper 5 so that the anti-jump limit frame 43 is aligned with the storage hopper 5. Specifically, each feeding machine 4, rotating baffle 8, and packaging machine 3 establish a batch tracking system for the storage hopper 5. During the conveying process of the packaging production line, the rotating baffle 8 and packaging machine 3 detect the storage hopper 5 through the batch tracking system and record the batch information of the storage hopper 5 in real time. During operation, the storage hopper 5 is conveyed on the circulating line 1. When the storage hopper batch tracking system of the first rotating baffle 8 detects the storage hopper 5, it will block the forward conveying of the storage hopper 5. At this time, the anti-jump limit frame 43 of the feeding mechanism 41 of the feeding unit 4 is aligned with the storage hopper 5. After the feeding unit 4 releases the material, the first rotating baffle 8 releases the storage hopper 5 to continue forward so that it is conveyed to the next feeding unit 4. Each rotating baffle 8 can operate on each storage hopper 5 in this way, ensuring the accuracy of material release of each feeding unit 4.

[0036] The packaging machine has a sorting device below the three-sealed bag opening. The sorting device includes a sorting chamber, a rotating mechanism, a waste discharge channel, and a finished product channel. The rotating mechanism can connect the sorting chamber to the waste discharge channel or the finished product channel. That is, the sorting device can sort non-finished material bags and finished material bags to ensure the accuracy of the output material bags.

[0037] During operation, the main control system of the packaging production line first scans and collects material images, processes and analyzes them to generate material type X. i(i=1,2,…,n) Information BOM table, and allocate the information to each feeding machine 4. The corresponding type of material is poured into each feeding machine 4 manually. When the material enters the unloading mechanism 41, the counting sensor 42 on each feeding machine 4 will count to determine the quantity N of each type of material entering the unloading mechanism 41. i (i=1,2,…,n),X i (i=1,2,…,n) and N i (i=1,2,…,n) represents the feed information;

[0038] Next, the material in the feeding mechanism 41 falls into the storage hopper 5 through the anti-jump limit frame 43. During this process, the feeding vision detection mechanism 6 captures images of the passing material and, combined with an algorithm, identifies the type Y of material being fed by each feeding unit 4. i (i=1,2,…,n), and count the number M of each type of material passing through the visual inspection mechanism 6. i (i=1,2,…,n),Y i (i=1,2,…,n) and M i (i=1,2,…,n) represents the output information. The industrial control system of each feeding machine (4 units) processes the X values ​​in the feeding and output information. i and Y i M i and N i The two sets of data are compared and analyzed in real time, and the analysis information is transmitted to the main control system of the packaging production line.

[0039] After receiving material from multiple feeding units 4, the material hopper 5 is lifted by the elevator 2 at the end of the circulation line 1, and finally unloaded and packaged at the unloading hopper 31. The unloading vision detection mechanism 7 captures images of the materials passing through during the unloading process, identifies the total material types K using an algorithm, and counts the total material quantity Q; K and Q are the unloading information. The main control system of the packaging production line monitors Q and the M of the same storage hopper 5. i The totals are compared and analyzed; the quantitative analysis relationship is as follows: ;

[0040] During the operation of the packaging production line, the main control system records the material status of all batches in hopper 5 and analyzes the data: if all Y materials in hopper 5 of the same batch are... i =X i (i=1,2,…,n) and all M i =N i(i=1,2,…,n), and satisfying the quantitative analysis relationship, when all three conditions are met, the material bag output from hopper 5 of this batch of information will be considered to meet the requirements of the finished product bag, and the main control system will control the sorting device to rotate this material bag to the finished product channel and output the finished product bag; if in hopper 5 of the same batch of information, Y i ≠X i or M i ≠N i Or the quantity analysis relationship is not satisfied, that is, there exists a material type Y of one of the feeding machines 4. i and X i The material quantity M of one of the feeders is mismatched or is not specified. i and N i If the quantities are not equal or do not meet the quantitative analysis formula, as long as one of the three conditions is met, the material bag output from the storage hopper 5 of this batch of information will be regarded as not meeting the requirements of the finished product bag. The main control system will control the sorting device to rotate the corresponding material bag to the impurity discharge channel to complete the impurity discharge of the non-finished product bag.

[0041] Finally, after the finished product packages and non-finished product packages are sorted out, the storage hopper 5 returns to the circulation line 1. At the same time, the main control system will clear the material analysis results corresponding to the batch information of the storage hopper 5, so as to avoid the overlap of the material analysis results corresponding to the batch information of the storage hopper 5 in the next cycle and the previous cycle, and further improve the accuracy of the data.

[0042] Throughout the process, the feeding and discharging information is compared and analyzed by the industrial control system of the feeding unit 4, and the discharging information and the discharging information of multiple feeding units 4 are summarized and compared by the main control system of the packaging production line. This dual comparison and analysis greatly improves the accuracy of the quantity and type of materials in the finished product packages. In addition, the batch tracking system of the storage hopper 5 is established to ensure that the batch information of the same storage hopper 5 can be traced throughout the operation of the packaging production line. This allows for accurate determination of whether the package output by the storage hopper 5 of a certain batch is a finished product package or a non-finished product package.

[0043] Furthermore, such as Figure 4 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.

[0044] Furthermore, such as Figure 6 and Figure 7As 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 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 through and transmits the information to the main control system. The transition structure 73 can disperse the material first, which can avoid the stacking of material affecting the subsequent detection of the second camera 71, thus improving the accuracy of visual inspection to a certain extent.

[0045] 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.

[0046] Furthermore, such as Figure 5 As shown, the rotating hopper 8 includes a rotating driver 81, a rotating stop bar 82, and a rotating bracket 83. The rotating driver 81 is fixed to the circulating line 1 via the rotating bracket 83. The driving end of the rotating driver 81 is drivenly connected to the rotating stop bar 82. Specifically, the hopper batch tracking system has two modes. When the hopper batch tracking system senses the hopper 5, it activates the blocking mode, that is, the rotating driver 81 drives the rotating stop bar 82 to rotate, thereby blocking the hopper 5 from being conveyed forward. When the industrial control system executes the material release command, the hopper batch tracking system activates the releasing mode, that is, the rotating driver 81 drives the rotating stop bar 82 to rotate to the initial state, thereby releasing the hopper 5 so that it can be conveyed forward to the next feeding unit 4.

[0047] Furthermore, the packaging machine 3 is equipped with a material bag barcode system at the sealing opening for scanning and reading the barcode on the material bag. The material bag barcode system converts the read information into a digital signal and transmits it to the main control system. When the same batch of information is stored in the storage hopper 5, Y i ≠X i or N i ≠M iIf the quantity analysis relationship is not met, the corresponding feeder single machine 4 industrial control system will determine the specific missing or extra material types and corresponding quantities during the conveying process, and the main control system will determine the specific missing or extra material types and corresponding 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.

[0048] 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 single machine 4 industrial control system will determine that there is no shortage or excess of material during the conveying process, and the main control system will determine that there is no shortage or excess of material during the unloading process. Finally, the main control system will link the absence of shortage or excess of material to the barcode of the corresponding material bag, and this material bag will be identified as a finished product material bag.

[0049] Finally, a manual barcode scanner is used to scan the barcode of the non-finished material package to read and query information on whether the non-finished material package is missing or has excess material. Based on the output information, the material type and quantity are supplemented, thus turning the non-finished material package into a finished material package.

[0050] In other embodiments, the feeding unit 4 is equipped with a feeding vision inspection mechanism in front of the feeding port of the unloading mechanism 41. Therefore, in this embodiment, the material type X i The information is obtained by capturing images of the material to be fed into the feed inlet of the unloading mechanism 41 through each feeding vision inspection unit and combining them with an algorithm for identification.

[0051] In summary, in this utility model, the feeding port of the feeding mechanism 41 is equipped with an anti-jump limit frame 43 to prevent the material from bouncing out of the storage hopper 5 due to collision after being placed into the storage hopper 5; the feeding port of the feeding mechanism 41 is designed with a counting sensor 42 to count the incoming material; the anti-jump limit frame 43 is equipped with a feeding visual inspection mechanism 6 to capture and process images of the passing material; the industrial control system of the feeding unit 4 compares and analyzes the feeding information and the output information to ensure that the two match; and the unloading hopper 31 between the top of the packaging machine 3 and the elevator 2 is equipped with an unloading visual inspection mechanism. The measuring mechanism 7 captures and processes images of the passing materials. The main control system of the packaging production line summarizes and compares the material pouring information and the output information of multiple feeding machines 4 to ensure that the two match. This dual comparison and analysis greatly improves the accuracy of the quantity and type of materials in the finished product packages. Secondly, each feeding machine 4 is equipped with a rotating baffle 8 to position the storage hopper 5, so that the materials can be accurately placed into the storage hopper 5. In addition, a sorting device is provided below the sealing opening of the packaging machine 3 to exclude non-finished product packages, further ensuring the accuracy of the finished product packages.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
