[0030] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, a material label screening and detection device includes a frame mechanism 1, a material conveying mechanism 2, a workstation conveying mechanism 3, a qualified product pushing mechanism 7, and a defective product discharging mechanism 8.

[0031] Both the material conveying mechanism 2 and the workstation conveying mechanism 3 are mounted on the frame mechanism 1, and the material outlet of the material conveying mechanism 2 is connected to the material inlet of the workstation conveying mechanism 3.

The frame mechanism 1 is provided with a qualified product pushing mechanism 7 and a defective product discharging mechanism 8 on the outside of the detection and sorting station 6.

[0033] The material is conveyed to the inlet of the feeding station 4 through the material conveying mechanism 2. The material is then conveyed to the transition station 5 and the inspection and sorting station 6 in sequence through the station chain plate 32. The material is inspected at the inspection and sorting station 6. If the material is qualified, it is pushed by the qualified product pushing mechanism 7. If the material is defective, it is discharged and recycled by the defective product discharge mechanism 8.

[0034] like Figure 3 , 4 As shown in Figures 5 and 6, to make the structure more reasonable and to facilitate the delivery of materials from the conveying mechanism 2 to the workstation conveying mechanism 3, the material conveying mechanism 2 includes a first motor 21, a conveyor belt 22, and baffles 23. The first motor 21 is mounted on the frame mechanism 1. The conveyor belt 22 is driven by rotating shafts located at both ends of the frame mechanism 1 and is arranged perpendicularly to the workstation chain plate 32. The output shaft of the first motor 21 is driven by one of the rotating shafts. Baffles 23 are respectively provided on the frame mechanism 1 on both sides of the conveyor belt 22. One end of the conveyor belt 22 is the material outlet and is connected to the inlet of the feeding station 4 on one side of the workstation chain plate 32. In use, the first motor 21 drives the conveyor belt 22 to transport the material on the conveyor belt 22 to the workstation chain plate 32 and into the inlet of the feeding station 4.

[0035] like Figure 2 , 3As shown in Figure 4, to ensure the stability and accuracy of the conveying of the station chain plate 32, the power source 31 includes a servo motor 33 and a reducer 34. Both the servo motor 33 and the reducer 34 are mounted on the frame mechanism 1. The power output shaft of the servo motor 33 is drive-connected to the input shaft of the reducer 34. The station conveying mechanism 3 also includes nylon rollers 35 and transition rollers 36. The frame mechanism 1 has multiple nylon rollers 35 and transition rollers 36 rotatably connected to them. The station chain plate 32 is drive-connected to the nylon rollers 35 and transition rollers 36. The power output shaft of the reducer 34 is drive-connected to one of the nylon rollers 35. This invention controls the station chain plate 32 to move precisely each time through the servo motor 33 and the reducer 34, enabling the material on the station chain plate 32 to accurately enter different workstations.

[0036] like Figure 3 , 5 As shown in Figure 6, to facilitate the detection of whether material enters the station chain plate 32, the feeding station 4 includes a first photoelectric sensor 41 and a first photoelectric sensor mounting base 42. The first photoelectric sensor mounting base 42 is mounted on the frame mechanism 1 and located outside the station chain plate 32. The first photoelectric sensor 41 is fixed on the first photoelectric sensor mounting base 42, and the sensing head of the first photoelectric sensor 41 is aligned with the entrance of the feeding station 4 to detect whether material enters. If material enters, the first photoelectric sensor 41 emits a photoelectric signal.

[0037] like Figure 3 , 5 As shown, to ensure the seamless connection between the material entering the feeding station 4 and the inspection and sorting station 6, the transition station 5 includes baffles 51 on both sides of the station chain plate 32. The baffles 51 are located between the feeding station 4 and the inspection and sorting station 6, and are L-shaped. Each baffle 51 has an oval through hole. The present invention allows for adjustment of the baffle 51's installation position according to actual production needs, and its fixed connection to the frame mechanism 1.

[0038] like Figure 5 , 6As shown, in order to detect whether materials meet product requirements, the detection and sorting station 6 includes a second photoelectric sensor 61, a second photoelectric sensor mounting base 62, a displacement sensor 63, a mounting base 64, an adjusting block 65, and a material pusher plate 66. The second photoelectric sensor mounting base 62 and the mounting base 64 are respectively located on both sides of the station chain plate 32. The second photoelectric sensor 61 is mounted on the second photoelectric sensor mounting base 62 and located above the station chain plate 32. The adjusting block 65 is fixed to the mounting base 64 by fasteners. The displacement sensor 63 is located on the adjusting block 65, and the sensing head of the displacement sensor 63 is fixedly connected to the material pusher plate 66. In use, when materials enter the detection and sorting station 6, the second photoelectric sensor 61 detects whether there is a label on the material. The sensing head of the displacement sensor 63 drives the material pusher plate 66 to move together. The size of the material is determined based on the position detected by the displacement sensor 63 to determine whether it meets the technical requirements. The second photoelectric sensor mounting base 62 of this invention is equipped with a vision system, which detects whether the materials meet the qualified product requirements. The adjusting block 65 can be adjusted in position on the mounting base 64 according to production requirements.

[0039] like Figure 6 As shown, in order to make the structure more reasonable and to ensure the linearity of the material pusher plate 66, a bracket 67 is provided on the second photoelectric sensor mounting base 62, the second photoelectric sensor 61 is mounted on the bracket 67, guide sleeves 68 are provided at both ends of the adjusting block 65, and guide posts 69 are provided at both ends of the material pusher plate 66. The guide posts 69 are inserted into the guide sleeves 68 and slide with them.

[0040] like Figure 6 As shown, in order to achieve automatic sorting of qualified products after material inspection, the qualified product pushing mechanism 7 includes a second motor 71, an eccentric power disk 72, a linkage rod 73, a qualified product push plate 74, a qualified product transfer plate 75, and a guide rail 76. The second motor 71 is mounted on the frame mechanism 1 and located on one side of the station chain plate 32. The eccentric power disk 72 is connected to the power output shaft of the second motor 71. The eccentric power disk 72 is integrated with the qualified product push plate 74 through the linkage rod 73. The qualified product push plate 74 is slidably engaged with the guide rail 76 mounted on the frame mechanism 10. The qualified product transfer plate 75 is located on the other side of the station chain plate 32 and is arranged opposite to the qualified product push plate 74. When in use, if the material is qualified, the second motor 71 drives the eccentric power disk 72 to rotate, and at the same time, through the action of the linkage rod 73, it drives the qualified product push plate 74 to slide along the guide rail 76, so that the qualified product push plate 74 pushes the qualified product on the station chain plate 32 into the qualified product transfer plate 75.

[0041] like Figure 5As shown, in order to achieve automatic sorting of defective products after material inspection, the defective product discharge mechanism 8 includes a receiving hopper 81 located at one end of the frame mechanism 1. If the material is defective, it will be conveyed by the station chain plate 32 and fall into the receiving hopper 81 for discharge and recycling. In use, if the material on the station chain plate 32 is defective after inspection, the station chain plate 32 will continuously move the defective product, and after moving to the end of the station chain plate 32, it will fall freely into the receiving hopper 81 for discharge and recycling.

[0042] like Figure 6 As shown, in order to position the material on the station chain plate 32 so that the subsequent feeding station can detect whether there is material and the detection and sorting station 6 can detect whether the material meets the product requirements, the station chain plate 32 is provided with multiple material positioning blocks 321 arranged at equal intervals. In order to detect the accuracy of the moving distance of the station chain plate 32 in real time and to adjust the moving speed of the station chain plate 32 in real time, a displacement sensor is provided on one side of the station chain plate 32 and outside the detection and sorting station 6.

[0043] The working process of this invention: Before use, the invention is set between the labeling machine and the bundle packaging machine;

[0044] Material conveying: During operation, after a single material is labeled and coated on the labeling machine, it enters the material conveying mechanism 2 through the discharge port of the labeling machine. The first motor 21 drives the conveyor belt 22 to move the material on the conveyor belt 22. The baffles 23 on both sides of the conveyor belt 22 can ensure that the material does not move in the radial direction during the conveying process of the conveyor belt 22.

[0045] Feeding: The conveyor belt 22 transports the material to the station chain plate 32 of the station conveying mechanism 3 arranged perpendicular to it. The servo motor 33 drives the station chain plate 32 to transmit through the reducer 34 and enter the inlet of the feeding station 4. If material enters, the first photoelectric sensor 41 emits a photoelectric signal and the material continues to move to the transition station 5.

[0046] Sorting: The material enters the inspection and sorting station 6 from the transition station 6. When the material enters the inspection and sorting station 6, the second photoelectric sensor 61 detects whether there is a label on the material. The sensing head of the displacement sensor 63 drives the material push plate 66 to move together. Based on the position detected by the displacement sensor 63, it is determined whether the size of the material meets the technical requirements. If the material is qualified, the second motor 71 drives the eccentric power disk 72 to rotate. At the same time, through the action of the linkage rod 73, the qualified product push plate 74 slides along the guide rail 76, so that the qualified product push plate 74 pushes the qualified product on the station chain plate 32 into the qualified product transfer plate 75 and then into the feeding inlet of the cluster packaging machine. If the defective product is on the station chain plate 32, the station chain plate 32 drives the defective product to move continuously and then falls freely into the receiving hopper 81 for discharge and recycling after moving to the end of the station chain plate 32.

[0047] This invention is used in conjunction with a film applicator and a bundled packaging machine to form an automated and highly integrated production line, which greatly improves the automation level of material packaging and replaces the manual sorting and transfer of qualified products in existing technologies. It can not only automatically screen and inspect materials, but also has high production efficiency, replacing manual sorting and reducing labor intensity.

[0048] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
