Description

Technical Field

[0001] This invention belongs to the field of geotechnical material manufacturing technology, and relates to the processing equipment and methods for geocells, specifically a production quality traceability system and production and traceability method for geocells and geocell sheets. Background Technology

[0002] In the manufacturing process of geocells, since geocells are composed of multiple sheets through welding, injection molding, and other methods, the quality of the sheets directly affects the quality of the finished product. A typical geocell is formed from 6-80 sheets welded and injection molded together. The sheets are then extruded, calendered, and cut. Assuming an extrusion capacity of 3 tons / day, and a sheet thickness × height × length of 1mm × 100mm × 7.5m, with 10 sheets produced per cut, the daily production capacity is approximately 4100 sheets, or about 170 sheets per hour. This demonstrates the large quantity of geocells produced.

[0003] The use of cell sheets is also quite diverse. Sometimes cell sheets are used immediately after production for the final product, sometimes they are stored, and sometimes a mixture of cell sheets that are in stock and those that are immediately off the production line are used in production.

[0004] As we all know, QC has traceability requirements. On the one hand, when problems occur, it is easier to find the cause and analyze it, so as to take corrective measures; on the other hand, when the product is unqualified due to problems such as raw materials, it is necessary to find out the products produced using these raw materials. The geocell sheet can be considered as the "raw material" for making geocell products.

[0005] In addition, there is another situation where 5-10 or even more grid panels are cut at a time, and due to various reasons, the quality of certain grid panels in certain fixed positions is problematic for a period of time. In this case, it is necessary to find out the products produced from these grid panels.

[0006] If it is not possible to accurately identify the products produced from the problematic "raw materials," it will lead to missed inspections and ultimately quality problems in the use of the products. Another possibility is that the range of products produced from the substandard "raw materials" will be expanded, resulting in a huge waste when dealing with these products.

[0007] Currently, the "raw material" cell plates used in products in the industry are usually represented by process cards, which simply identify a period of time or even a shift of cell plate information; or there are no records at all, which makes traceability very difficult, and even impossible to some extent.

[0008] In summary, traditional batch confusion and quality traceability methods suffer from low efficiency and poor accuracy, making it difficult to meet the stringent requirements of modern manufacturing for product quality control.

[0009] Therefore, designing and developing a production quality traceability system and production and traceability method for geocells and geocell sheets that can effectively solve problems such as batch confusion and difficulty in quality traceability, help improve product traceability, ensure product quality, and enhance market competitiveness has become an urgent need for industry development. Summary of the Invention

[0010] This invention addresses the problems and shortcomings of existing technologies by providing a production quality traceability system and method for geocells and geocell sheets. This system enables precise traceability and quality control of geocell sheets, effectively solving problems such as batch confusion and difficulty in quality traceability, thus improving product traceability and ensuring product quality.

[0011] The objective of this invention is achieved through the following technical solution: a production quality traceability system for geocells and geocell sheets, comprising an extruder, a shearing machine, a geocell sheet assembly device, and a control system. A sheet cutting and conveying device and a geocell sheet conveying device are respectively installed before and after the shearing machine. The sheet cutting and conveying device is used to cut the sheet output from the extruder into strip-shaped sheets and convey them to the shearing machine. The geocell sheet conveying device is used to output the geocell sheets formed after the shearing machine cuts the strip-shaped sheets. The geocell sheet assembly device is used to partially connect several geocell sheets one by one to form a geocell. The invention is characterized by the installation of a coding device or marking device on the shearing machine. A marking device is installed on one end of the geocell sheet to form a unique identification code on each geocell sheet, including the production time and the sequence number along the width of the equipment. A geocell marking device is installed on the geocell sheet assembly to form a product identification code on the last geocell sheet in the geocell production process. An image acquisition device is installed on the geocell sheet assembly to collect and identify the identification codes of each geocell sheet in the geocell production process. The marking device, the image acquisition device, and the geocell marking device are respectively connected to the control system. The control system includes a database for storing the identification codes on the geocell sheets and the product identification codes on the geocells.

[0012] Improvements to the above technical solution: The cell panel bonding device adopts a welding machine or an injection molding machine, and the welding machine includes a welding head, a frame and an upper track.

[0013] Further improvements to the above technical solution: The image acquisition device is installed at one end of the upper track of the welding machine, and the geocell coding device is installed on the frame near the first welding head of the welding machine. It is used to code the last geocell sheet to form a unique product identification code. The product identification code includes a batch number and a serial number. The batch number is the order number for this batch of products, and the serial number is the quantity counted at the start of production for this batch of products. The image acquisition device identifies the identification code on the geocell sheet and compares it with the database. If the geocell sheet cannot be used for the production of this batch of products, an alarm is triggered; otherwise, the identification code is recorded in the database and corresponds to the product identification code.

[0014] Further improvements to the above technical solution: The grid coding device includes a nozzle and a mounting bracket assembly. The mounting bracket assembly is mounted on the frame of the welding machine, and the nozzle is mounted on the mounting bracket assembly. The mounting bracket assembly is used to adjust the spraying angle, height, and range of the nozzle.

[0015] Further improvements to the above technical solution: The cell sheet conveying device includes a conveying frame and a drive roller and conveyor belt on the conveying frame; the sheet slitting and conveying device includes a driven frame, a driven roller on the driven frame, a traction device and an adjustable cutter, the adjustable cutter includes a cutter mounting frame and multiple adjustable-spacing slitting cutters on the cutter mounting frame, the cutter mounting frame is laterally arranged on one end of the driven frame, and a pair of traction rollers at the output end of the extruder are located on the other end of the driven frame; a cutting blade is arranged in the middle of the shearing machine, and an adjustable bracket is laterally arranged at the rear of the shearing machine near the cutting blade, the inkjet printer or coding device is mounted on the adjustable bracket.

[0016] The present invention discloses a production and traceability method for the production quality traceability system of the above-mentioned geocells and sheets, characterized in that it includes a production method and a traceability method, wherein the production method includes the following steps:

[0017] Step 1: The sheet produced by the extruder is conveyed to the sheet slitting and conveying device to be slitted into strip sheets and then conveyed to the shearing machine. The shearing machine cuts the strip sheets into several compartment sheets. After inkjet printing or coding at one end of each compartment sheet, a unique identification code is formed. The identification code includes the production time and the sequential number along the width of the equipment.

[0018] Step 2: The geocell sheets with marking codes are transported out by the geocell sheet conveying device for use in the fabrication of geocells;

[0019] Step 3: When the welding machine or injection molding machine starts producing a batch of geocells for an order, the control system sets the number of geocell sheets N used per geocell and inputs the product batch number into the control system.

[0020] Step 4: Place the first geocell sheet with the identification code on the processing station of the welding machine or injection molding machine, with the identification code facing upwards and close to the image acquisition device. Click "Start". The control system generates a unique product identification code for each geocell produced. The product identification code includes the product batch number and the serial number. The product batch number is the order number for this batch of products, and the serial number is the quantity of geocells produced in this batch of products. The database in the control system stores the product identification codes. The image acquisition device identifies the identification code on the geocell sheet and compares it with the database. If the geocell sheet cannot be used for the production of this batch of products, an alarm is triggered; otherwise, the identification code is recorded in the database and corresponds to the product identification code.

[0021] Step 5: Place the next cell sheet with the identification code on the processing position of the welding machine or injection molding machine, above the previous cell sheet, with the identification code facing upwards and close to the image acquisition device. Click "Start". The image acquisition device identifies the identification code on the cell sheet and compares it with the database. If the cell sheet cannot be used for the production of this batch of products, an alarm will be triggered; otherwise, the identification code will be recorded in the database and matched with the product identification code. Then, the upper cell sheet will be intermittently fixed to the lower cell sheet.

[0022] Step 6: Following the method in Step 5, weld or injection mold the remaining cell panels one by one until the Nth cell panel is welded or injection molded. Record all the identification codes on each cell panel into the database. Finally, use a cell marking device to spray the product identification code on one end of the Nth cell panel.

[0023] Step 7: After the geocell product comes off the production line, both sides are neatly cut. The identification codes of each cell are cut off, leaving only the product identification code of the geocell. This completes one geocell product.

[0024] Improvements to the above technical solution: In step 1, an identification code is sprayed on one side of the geocell sheet, 5-10cm from end 3 of the shearing machine. The identification code consists of 14 digits, the first 8 digits are the date the geocell sheet is produced, the middle 4 digits are the specific time and minute the geocell sheet is produced, and the last two digits are the sequence number, which is the order from one side of the shearing machine to the other side. The database of the control system stores the raw materials, production process and inspection results of the geocell sheets used in the geocell products, as well as the production process and inspection results of the geocell products.

[0025] Further improvements to the above technical solution: Each grid cell is 2-8 meters long and 0.05-0.30 meters wide.

[0026] The present invention discloses a production and traceability method for the production quality traceability system of the above-mentioned geocells and sheets, characterized in that the traceability method includes at least one or more of the following traceability modes:

[0027] Traceability Method 1: Geocell Product Traceability of Cell Sheets: Traceability of single or multiple geocell products: Input the identification code of a single or multiple products to display the production date and time of the geocell product, as well as the identification codes and welding sequence of all the cell sheets used in the geocell product, thereby obtaining the production date, time and location of the cell sheets used in the geocell product;

[0028] Traceability Method 2: Traceability of Geocell Products by Cell Sheet: Enter the identification code of the geocell sheet you want to find, and the product identification code, production time, and position of the geocell sheet in the geocell product will be displayed.

[0029] Traceability Method 3: Geocell Sheet Offline Time and Production Usage Time: Select geocell sheets for a certain period of time, and a histogram will show the time interval between these geocell sheets leaving the production line and the production of geocells; select the geocell product production range, and a histogram will show the time interval between the geocell sheets used in the production of these geocell products leaving the production line and the production usage time.

[0030] Further improvements: In the first traceability method, the traceability results are output as a file and saved; the traceability content also includes: obtaining the raw materials, production processes, and inspection and testing results used in the production of the geocell sheets used in the geocell products;

[0031] In the second traceability method, the traceability results are output as a file and saved; the traceability content also includes the production process and inspection and testing results of the geocell products.

[0032] Compared with the prior art, the advantages and positive effects of the present invention are:

[0033] 1. This invention achieves fast and accurate coding or inkjet coding of formatted films through laser coding or inkjet coding technology, resulting in high production efficiency.

[0034] 2. This invention combines image recognition technology to achieve automatic identification and recording of format slice information, reducing errors and omissions caused by manual operation.

[0044] To further understand the invention's content, features, and effects, the following embodiments are provided and described in detail with reference to the accompanying drawings:

[0045] See Figures 1-6This invention discloses an embodiment of a production quality traceability system for geocells and geocell sheets, comprising an extruder, a shearing machine 4, a geocell sheet bonding device, and a control system. A sheet cutting and conveying device and a geocell sheet conveying device are respectively installed before and after the shearing machine 4. The sheet cutting and conveying device cuts the sheet output from the extruder into strips and conveys them to the shearing machine. The geocell sheet conveying device outputs the geocell sheets formed after the shearing machine cuts the strips. The geocell sheet bonding device connects several geocell sheets piece by piece to form geocells. A coding device or marking device is installed on the shearing machine 4. The coding device or marking device is used to print or mark codes on one end of each geocell sheet, forming a unique identification code on each geocell sheet including the production time and a sequential number along the width of the equipment. A cell coding device 13 is installed on the cell assembly device to form a product identification code on the last cell piece in the geocell assembly. An image acquisition device 10 is installed on the cell assembly device to collect and identify the identification codes of each cell piece in the geocell assembly. The coding device, the image acquisition device 10, and the cell coding device 13 are respectively connected to the control system. The control system includes a database for storing the identification codes on the cell pieces and the product identification codes on the geocells.

[0046] Furthermore, the above-mentioned cell panel assembly device uses a welding machine or an injection molding machine. The welding machine includes an upper rail 11 of the welding production line, a frame 9, and a number of welding heads 8 arranged sequentially on the upper rail 11.

[0047] Furthermore, the aforementioned geocell marking device 13 is installed on the frame 9 near the first welding head 8 of the welding machine. It is used to mark the last geocell sheet to form a unique product identification code. The product identification code includes a batch number and a serial number. The batch number is the order number for this batch of products, and the serial number is the quantity counted at the start of production for this batch. The aforementioned control system includes a database for storing product identification codes. The image acquisition device 10 identifies the identification code on the geocell sheet and compares it with the database. If the geocell sheet cannot be used for production of this batch of products, an alarm is triggered; otherwise, the identification code is recorded in the database and correlated with the product identification code. Figure 4 The image acquisition range 10.1 of the image acquisition device 10 is shown in the image acquisition device 10.

[0048] Furthermore, the aforementioned grid coding device 13 includes a printhead and a mounting bracket assembly. The mounting bracket assembly is mounted on the frame 9, and the printhead is mounted on the mounting bracket assembly. The mounting bracket assembly is used to adjust the spray angle and range of the printhead. Specifically, the mounting bracket assembly is assembled from a front and rear adjusting rod 14, a vertical adjusting rod 15, a fixing clamp 16, and a suction cup base 17. Figure 4 As shown.

[0049] Furthermore, the aforementioned cell sheet conveying device includes a conveying frame 6 and a drive roller and conveyor belt on the conveying frame 6; the aforementioned sheet slitting and conveying device includes a driven frame 2, driven rollers on the driven frame 2, a traction device 5, and an adjustable cutter 3. The adjustable cutter 3 includes a cutter mounting frame and multiple adjustable-spacing slitting cutters on the cutter mounting frame. The cutter mounting frame is laterally arranged on one end of the driven frame 2, and a pair of traction rollers 1 at the output end of the extruder are located on the other end of the driven frame 2; a cutting blade is provided in the middle of the shearing machine, and an adjustable bracket 7 is laterally arranged at the rear of the shearing machine near the cutting blade. The inkjet printing device or coding device is installed on the adjustable bracket 7.

[0050] See Figures 1-6 An embodiment of the production and traceability method of the above-mentioned geocell and sheet production quality traceability system of the present invention includes a production method and a traceability method. The production method includes the following steps:

[0051] Step 1: The sheet produced by the extruder is conveyed to the sheet slitting and conveying device to be slitted into strip sheets and then conveyed to the shearing machine. The shearing machine 4 cuts the strip sheets into several compartment sheets. After inkjet printing or coding at one end of each compartment sheet, a unique identification code is formed. The identification code includes the production time and the sequential number along the width of the equipment.

[0052] Step 2: The geocell sheets with marking codes are conveyed out by the geocell sheet conveying device for use in the welding machine to process geocells;

[0053] Step 3: When the welding machine or injection molding machine starts producing a batch of geocells for an order, the control system sets the number of geocell sheets N used per geocell and inputs the product batch number into the control system.

[0054] Step 4: Place the first geocell sheet with the identification code on the processing station of the welding machine or injection molding machine, with the identification code facing upwards and close to the image acquisition device. Click "Start". The control system generates a unique product identification code for each geocell produced. The product identification code includes the product batch number and the serial number. The product batch number is the order number for this batch of products, and the serial number is the quantity of geocells produced in this batch of products. The database in the control system stores the product identification codes. The image acquisition device identifies the identification code on the geocell sheet and compares it with the database. If the geocell sheet cannot be used for the production of this batch of products, an alarm is triggered; otherwise, the identification code is recorded in the database and corresponds to the product identification code.

[0055] Step 5: Place the next cell sheet with the identification code on top of the previous cell sheet in the processing position of the welding machine or injection molding machine, so that the cell sheet (i.e., Figure 2With the label code of the grid piece 12 to be welded facing upwards and close to the image acquisition device, click start. The image acquisition device identifies the label code on the grid piece and compares it with the database. If the grid piece cannot be used for the production of this batch of products, an alarm will be triggered; otherwise, the label code will be recorded in the database and corresponded with the product label code. Then, the upper grid piece and the lower grid piece will be intermittently fixed together.

[0056] Step 6: Following the method in Step 5, weld or injection mold the remaining cell panels one by one until the Nth cell panel is welded or injection molded. Record all the identification codes on each cell panel into the database. Finally, use a cell marking device to spray the product identification code on one end of the Nth cell panel.

[0057] Step 7: The geocell product comes off the production line. The sides are neatly trimmed, and the identification codes for each cell are cut off, leaving only the product identification code for the geocell. This completes one geocell product (18). Figure 5 As shown.

[0058] Further, in step 1 above, an identification code is sprayed on one side of the grid sheet, 5-10cm from the end of the shearing machine 4. The identification code consists of 14 digits: the first 8 digits represent the date the grid sheet was produced, the middle 4 digits represent the specific time of production, and the last two digits are the sequence number, indicating the order from one side of the shearing machine 4 to the other. Preferably, in step 6 above, the product identification code is located within 5cm of the outermost weld joint.

[0059] The database of the control system stores the raw materials, production process and inspection results of the geocell sheets used in the geocell products, as well as the production process and inspection results of the geocell products.

[0060] For example, if the date of the cell panel's production line is September 6, 2024, then it is "20240906". The middle four digits are the production time of the cell panel, such as 22:10, which is "2210". The last two digits are the sequence number, which is the third piece counted from the left if the left side of the equipment is defined as the start. The identification code of this cell panel is "20240906221003".

[0061] For example: The product identification code includes the product batch number and the serial number. The product batch number is the order number for that batch of products, and the serial number is the quantity of geocells produced in that batch of products. The product batch number is entered during the first production run, and the serial number starts at 0001 by default and increases sequentially. For example, if the product batch number is 2024-09-10 and the serial number is 0001, then the product identification code is: 202409100001.

[0062] During processing and manufacturing, each cell panel is typically 2-8 meters long and 0.05-0.30 meters wide.

[0063] Furthermore, the traceability method includes at least one or more of the following traceability techniques:

[0064] Traceability Method 1: Geocell Product Traceability of Cell Sheets: Traceability of single or multiple geocell products: Input the identification code of a single or multiple products to display the production date and time of the geocell product, as well as the identification codes and welding sequence of all the cell sheets used in the geocell product, thereby obtaining the production date, time and location of the cell sheets used in the geocell product.

[0065] Traceability Method 2: Traceability of Geocell Products by Cell Sheet: Enter the identification code of the geocell sheet you want to find, and the product identification code of the geocell produced by that geocell sheet, the production date, and its position in the geocell product list will be displayed.

[0066] Traceability Method 3: Geocell Sheet Offline Time and Production Usage Time: Select geocell sheets for a certain period of time, and a histogram will show the time interval between these geocell sheets leaving the production line and the production of geocells; select the geocell product production range, and a histogram will show the time interval between the geocell sheets used in the production of these geocell products leaving the production line and the production usage time.

[0067] Further improvements: In the first traceability method, the traceability results are output as a file and saved; the traceability content also includes: obtaining the raw materials, production processes, and inspection and testing results used in the production of the geocell sheets used in the geocell products;

[0068] In the second traceability method, the traceability results are output as a file and saved; the traceability content also includes the production process and inspection and testing results of the geocell products.

[0069] For example: 1. By tracing the geocell sheets through geocell products, if a user discovers a quality problem with a geocell product after it has been sold, and the product identification code on the geocell product is 202409100001, the user can provide this product identification code to the manufacturer. The manufacturer can then query the control system database by entering 202409100001 to display the production date and time of the geocell product, as well as the identification codes and welding sequence of all the geocell sheets used in the product. This allows the manufacturer to quickly trace the product's origin, facilitating product quality control and adjustment.

[0070] 2. Trace geocell products by geocell sheet: Enter the identification code of the geocell sheet you want to find, 20240906221003, and you can see the product identification code of the geocell produced by that geocell sheet (e.g., 202409100001), the production date, and its position in the geocell products.

[0071] The control system of the present invention also has the following functions:

[0072] 1. The control system can select or input cell plates that cannot be used for production.

[0073] 2. The control system's database can output data analysis, such as the production time of the cell panels and the time spent on welding.

[0074] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.

The production methods include the following steps: Step 1: The sheet produced by the extruder is conveyed to the sheet slitting and conveying device to be slitted into strip sheets and then conveyed to the shearing machine. The shearing machine cuts the strip sheets into several compartment sheets. After inkjet printing or coding at one end of each compartment sheet, a unique identification code is formed. The identification code includes the production time and the sequential number along the width of the equipment. Step 2: The geocell sheets with marking codes are transported out by the geocell sheet conveying device for use in the fabrication of geocells; Step 3: When the welding machine or injection molding machine starts producing a batch of geocells for an order, the control system sets the number of geocell sheets N used per geocell and inputs the product batch number into the control system. Step 4: Place the first geocell sheet with the identification code on the processing position of the welding machine or injection molding machine, with the identification code facing upwards and close to the image acquisition device. Click "Start". The control system generates a unique product identification code for each geocell produced by welding. The product identification code includes the product batch number and the serial number. The product batch number is the order number for this batch of products, and the serial number is the quantity of geocells produced in this batch of products. The database in the control system stores the product identification codes. The image acquisition device identifies the identification code on the geocell sheet and compares it with the database. If the geocell sheet cannot be used for the production of this batch of products, an alarm is triggered; otherwise, the identification code is recorded in the database and corresponds to the product identification code. Step 5: Place the next cell sheet with the identification code on the processing position of the welding machine or injection molding machine, above the previous cell sheet, with the identification code facing upwards and close to the image acquisition device. Click "Start". The image acquisition device identifies the identification code on the cell sheet and compares it with the database. If the cell sheet cannot be used for the production of this batch of products, an alarm will be triggered; otherwise, the identification code will be recorded in the database and matched with the product identification code. Then, the upper cell sheet will be intermittently fixed to the lower cell sheet. Step 6: Following the method in Step 5, weld or injection mold the remaining cell panels one by one until the Nth cell panel is welded or injection molded. Record all the identification codes on each cell panel into the database. Finally, use a cell marking device to spray the product identification code on one end of the Nth cell panel. Step 7: After the geocell product comes off the production line, both sides are neatly cut. The identification codes of each cell are cut off, leaving only the product identification code of the geocell. This completes one geocell product.

5. The production and traceability method of the geocell and sheet production quality traceability system according to claim 4, characterized in that, In step 1, an identification code is sprayed on one side of the geocell sheet, 5-10cm from the shearing machine end. The identification code consists of 14 digits: the first 8 digits are the date the geocell sheet is produced, the middle 4 digits are the specific time and minute the geocell sheet is produced, and the last two digits are the sequence number, which is the order from one side of the shearing machine to the other. The database of the control system stores the raw materials, production process and inspection and testing results of the geocell sheets used in the geocell products, as well as the production process and inspection and testing results of the geocell products.
