Description

Technical Field

[0001] This application relates to the technical field of carton production, and in particular to a carton machine for automatic inkjet coding and inspection. Background Art

[0002] When some cartons are processed, in order to play an anti-counterfeiting role, two-dimensional codes generally need to be sprayed on the inner side of the cardboard, and users can scan the codes to check whether the packaged products are counterfeit.

[0003] The existing method generally sprays codes on cartons through automatic inkjet coding equipment. After the coding is completed, it is also necessary to detect through inspection equipment whether the sprayed two-dimensional code is unclear and cannot be scanned. The process is complex, which greatly reduces the production efficiency of cartons. Utility Model Content

[0004] The purpose of the present utility model is to solve or at least alleviate the problem that the steps of inkjet coding on cartons and two-dimensional code detection in the existing method are carried out separately, the process is complex, and the production efficiency of cartons is greatly reduced.

[0005] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0006] A carton machine for automatic inkjet coding and inspection includes a distribution box fixedly connected to a workbench at the top. One end of the upper surface of the distribution box is provided with a feeding component. The discharging end of the feeding component is provided with a feeding structure. Two brackets are fixedly connected to the workbench outside the feeding structure. The top of the bracket close to the feeding component is fixedly connected with an inkjet printer, and the top of the other bracket is fixedly connected with a camera. A material distribution component is arranged on the feeding structure inside the camera. A programmable logic controller for controlling the inkjet printer, the camera and the material distribution component is also installed on the distribution box.

[0007] By adopting the above technical solutions, during use, the user first drives two groups of feeding wheels to rotate in opposite directions through a motor to transport the cardboard to the feeding plate, so that the cardboard moves along the guiding groove. When the cardboard moves to the inkjet printer, the programmable logic controller controls the inkjet printer to start spraying two-dimensional codes on the cardboard. The sprayed cardboard continues to move along the guiding groove under the pushing action of the subsequent cardboard until it enters the detection range of the camera. At this time, the camera captures and identifies the sprayed two-dimensional code for quality inspection, and automatically distributes the cardboard with qualified and unqualified two-dimensional codes through the material distribution component. Since the inkjet coding and quality inspection are carried out on the same production line, it avoids as much as possible the problem that the steps of inkjet coding cartons and two-dimensional code detection in the existing method are carried out separately, the process is complex, and the production efficiency of cartons is greatly reduced.

[0008] Optionally, the loading assembly includes a support plate vertically fixedly connected to the upper surface of the workbench, and two groups of loading wheels with opposite rotation directions are rotatably connected to the support plate. Each loading wheel is provided with an annular groove, and a motor for driving the loading wheel to rotate is fixedly connected to the back of the support plate.

[0009] By adopting the above technical solution, when in use, the cardboard is placed in the gap between the two sets of feeding wheels, and then the motor is started, and the two sets of feeding wheels are driven by the motor to rotate in opposite directions, and the cardboard is transported in the direction of the feeding structure through the friction action box.

[0010] Optionally, gears are fixedly connected to the back of multiple loading wheels in each group, the same inner gear ring is mounted on the multiple gears in the same group, the multiple gears in the same group are meshed and transmission connected with the inner gear ring, and the output end of the motor passes through the support plate and is fixedly connected to the center of one of the gears.

[0011] By adopting the above technical solution, gears and inner gear rings are set, so that the multiple loading wheels in each group are connected to each other through gears and inner gear rings, so that when the motor drives one of the gears to rotate, it can drive the multiple loading wheels in each group to rotate synchronously, which facilitates loading.

[0012] Optionally, the feeding structure includes a feeding plate fixedly connected to the support plate via a connecting piece, and upper and lower side walls of the feeding plate are bent outward to form a guide groove, and the spacing between the two guide grooves is equal to the width of the cardboard to be coded.

[0013] By adopting the above technical solution, after the cardboard is output from between the two sets of feeding wheels, the upper and lower side walls of the cardboard respectively enter the guide grooves formed by the upper and lower bends on the feeding plate, and the cardboard is guided by the guide grooves. Under the push of the subsequent cardboard, the cardboard that first enters the guide groove is pushed forward until the cardboard is pushed to the inkjet printer for coding.

[0014] Optionally, the connecting member includes a connecting seat welded on the back side of one end of the conveying plate close to the supporting plate, and bolts are passed through both ends of the connecting seat. The bolts penetrate the connecting seat and are screwed to the supporting plate.

[0015] By adopting the above technical solution, a connecting seat is provided to facilitate the alignment of the guide groove with the annular groove provided on the feeding wheel, and a bolted connection method is adopted, which not only ensures a stable connection, but also facilitates the user to install and disassemble the feed plate.

[0016] Optionally, the height of the inkjet printer's coding position and the height of the camera's detection position are located on the same horizontal line.

[0017] By adopting the above technical solution, the two-dimensional code sprayed on the cardboard by the inkjet printer will inevitably pass by the camera as the cardboard moves along the feed plate, which is convenient for the camera to perform quality inspection on the two-dimensional code.

[0018] In summary, the beneficial effects of this application are as follows:

[0019] Through the coordinated setting of structures such as the feeding wheel, material conveying plate, guiding groove, inkjet printer, and camera, the cardboard is conveyed by the feeding wheel to the guiding groove formed by the bending on both sides of the material conveying plate. First, it passes through the inkjet printer for inkjetting, and under the push of the subsequent cardboard, the inkjet - printed cardboard is pushed to the camera for quality inspection. Finally, the programmable logic controller controls the telescopic movement of the electric telescopic rod to sort the qualified products and defective products. Since the inkjetting and quality inspection are carried out on the same production line, it avoids as much as possible the problem that the existing method separates the inkjetting of cartons and the two - dimensional code detection steps, with complex processes and greatly reducing the production efficiency of cartons.

Detailed Description of the Embodiment

[0024] The following will further elaborate on this application in conjunction with the attached Figures 1 - 3 drawings.

[0025] Please refer to Figures 1 - 3 , an automatic inkjet - printing and inspecting carton machine, including a distribution box 2 fixedly connected to the top of a workbench 1. An upper - feeding component is installed on the upper surface at one end of the workbench 1, and a material - conveying structure is installed at the discharging end of the upper - feeding component. When in use, the cardboard inspected by an external product inspection machine enters the upper - feeding component, and the upper - feeding component conveys the cardboard into the material - conveying structure and conveys the cardboard along the material - conveying structure.

[0026] Two supporting brackets 14 are fixedly connected to the workbench 1 outside the material - conveying structure. The inkjet printer 15 is fixedly connected to the top of the bracket 14 closer to the upper - feeding component. When the cardboard is conveyed along the material - conveying structure to the inkjet - printing position of the inkjet printer 15, the inkjet printer 15 is started to spray the two - dimensional code for anti - counterfeiting on the inner wall of the cardboard.

[0027] A camera 16 for identifying the QR code sprayed by the inkjet printer 15 is fixedly connected to the top of another bracket 14. The coded cardboard continues to move along the feeding structure under the push of subsequent cardboard. When the sprayed QR code moves to the detection position of the camera 16, the camera 16 can detect and identify the QR code and perform quality inspection on the sprayed QR code.

[0028] A material separation component is provided on the feeding structure inside the camera 16, and the material separation component is used to automatically separate the two-dimensional code cardboards that pass the quality inspection and those that fail the quality inspection, so as to facilitate the user and improve the sorting efficiency.

[0029] The distribution box 2 is also equipped with a programmable controller 18 for controlling the inkjet printer 15, the camera 16 and the material distribution assembly.

[0030] Reference Figure 1 The feeding assembly includes a support plate 3 vertically fixedly connected to the upper surface of the workbench 1, and two groups of feeding wheels 4 rotating in opposite directions are rotatably connected to the support plate 3. An annular groove 5 is provided on each feeding wheel 4, and a motor 8 for driving the feeding wheels 4 to rotate is fixedly connected to the back of the support plate 3. When in use, the cardboard is placed in the gap between the two groups of feeding wheels 4, and then the motor 8 is started, and the two groups of feeding wheels 4 are driven by the motor 8 to rotate in opposite directions, and the cardboard is transported in the direction of the feeding structure through the friction action box.

[0031] Reference Figure 2 , the back of the multiple feeding wheels 4 in each group are fixedly connected with a gear 6, the multiple gears 6 in the same group are sleeved with the same inner gear ring 7, the multiple gears 6 in the same group are meshed and connected with the inner gear ring 7, and the output end of the motor 8 passes through the support plate 3 and is fixedly connected with the center of one of the gears 6. The gear 6 and the inner gear ring 7 are arranged so that the multiple feeding wheels 4 in each group are connected with each other through the gear 6 and the inner gear ring 7, so that when the motor 8 drives one of the gears 6 to rotate, it can drive the multiple feeding wheels 4 in each group to rotate synchronously, which is convenient for feeding.

[0032] Reference Figure 3 The feeding structure includes a feeding plate 9 fixedly connected to the support plate 3 through a connecting piece. The upper and lower side walls of the feeding plate 9 are bent outward to form a guide groove 12. The distance between the two guide grooves 12 is equal to the width of the cardboard to be coded. After the cardboard is fed from between the two sets of feeding wheels 4, the upper and lower side walls of the cardboard enter the guide grooves 12 formed by the upper and lower sides of the feeding plate 9 respectively. The cardboard is guided by the guide grooves 12, and the cardboard that enters the guide groove 12 first is pushed forward by the subsequent cardboard until the cardboard is pushed to the inkjet printer 15 for coding.

[0033] Reference Figure 3The connecting piece includes a connecting seat 10 welded on the back of one end of the feed plate 9 close to the support plate 3, and bolts 11 are penetrated at both ends of the connecting seat 10. The bolts 11 penetrate the connecting seat 10 and are screwed to the support plate 3. The connecting seat 10 is provided to facilitate the alignment of the guide groove 12 with the annular groove 5 provided on the feeding wheel 4. The screw connection method of the bolt 11 is adopted, which is not only stable, but also convenient for users to install and disassemble the feed plate 9.

[0034] Reference Figure 1 The height of the inkjet printer 15 and the height of the detection position of the camera 16 are located on the same horizontal line. The two-dimensional code formed by the inkjet printer 15 on the cardboard will inevitably pass the camera 16 as the cardboard moves along the feed plate 9, which is convenient for the camera 16 to perform quality inspection on the two-dimensional code.

[0035] Reference Figure 1 The material separation component includes a material separation port 13 provided on the material feeding plate 9 inside the camera 16, and also includes an electric telescopic rod 17 fixedly connected to the bracket 14 on which the camera 16 is installed. The electric telescopic rod 17 is perpendicular to the material feeding plate 9, and the output end of the electric telescopic rod 17 is directly opposite to the center of the material separation port 13. When the camera 16 cannot recognize the QR code on the cardboard and transmits the information to the programmable controller 18, the programmable controller 18 immediately starts the electric telescopic rod 17 to extend, push the cardboard to bend and deform, and push out the unqualified cardboard from the material separation port 13, while the cardboard that can be recognized by the camera 16 is discharged from the end of the material feeding plate 9 away from the feeding component under the pushing action of the subsequent cardboard, so as to realize the material separation of the cardboard.

[0036] The implementation principle of the present application is as follows: when in use, the user first drives the two sets of feeding wheels 4 to rotate in opposite directions through the motor 8, transfers the cardboard to the feeding plate 9, and moves the cardboard along the guide groove 12. When the cardboard moves to the inkjet printer 15, the programmable controller 18 controls the inkjet printer 15 to start spraying a two-dimensional code on the cardboard. The cardboard after coding continues to move along the guide groove 12 under the push of subsequent cardboards until it enters the detection range of the camera 16. At this time, the camera 16 captures and identifies the sprayed two-dimensional code for quality inspection, and automatically separates the two-dimensional code cardboards that pass the quality inspection and those that fail the quality inspection through the material separation component. Since coding and quality inspection are carried out on the same assembly line, the existing method of separating the carton coding and the two-dimensional code detection steps is avoided as much as possible, which makes the process complicated and greatly reduces the problem of carton production efficiency.
