Technical Field

[0001] The invention relates to the technical field of packaging paper box production, in particular to a visual inspection machine for packaging paper box production. Background Art

[0002] Packaging cartons are devices used to pack items. They are mainly supported by corrugated paper. In the actual production process, in order to facilitate the viewing of product information, the surface of the packaging cartons is generally printed with relevant patterns and text descriptions. In order to ensure that the printed patterns or texts on the packaging boxes are clear and correct, visual inspection machines are often used to inspect the produced packaging cartons.

With the linked marking mechanism, the defective carton bodies can be marked for subsequent distinction. With the automatic ink replenishing structure, the clarity of the mark can be ensured. Specifically, the defective carton body can be pushed by the cylinder and the push plate, so that the defective carton body enters the collection box and is collected.

[0029] When using the visual inspection machine for packaging carton production, Figure 1-Figure 7 As shown, the carton body 3 to be inspected is placed on the left conveying mechanism 2, and the carton body 3 is moved from left to right through the left conveying mechanism 2. When the carton body 3 contacts the pressure roller 402 above the left conveying mechanism 2, the sliding action of the pressure roller 402 and the elastic action of the first spring 404 are coordinated, so that the pressure roller 402 generates a certain pressure on the carton body 3, thereby realizing the automatic flattening action of the carton body 3. At this time, the carton body 3 continues to move to the right. When the carton body 3 moves to below the industrial camera 502 on the upper side of the left conveying mechanism 2, the industrial camera 502 can realize the one-side inspection of the carton body 3.

The bracket 601 is fixed on the support frame 1, and the cylinder 602 is fixed on the bracket 601, and the push plate 603 is fixed on the output end of the cylinder 602, and the lower end surface of the push plate 603 is flush with the upper end surface of the transmission mechanism 2, and the support rod 609 is also fixed on the bracket 601; the push plate 603 is slidably connected to the movable frame 604, and the seal 605 is fixed on the movable frame 604, and the seal 605 and the push plate 603 are connected.

[0031] After the carton body 3 is detected, Figure 1-Figure 7As shown, when it is detected that the paper box body 3 has a defect, the defective paper box body 3 is moved to the front side of the unloading mechanism 6 through the transmission mechanism 2. At this time, the cylinder 602 extends to drive the push plate 603 to move forward, thereby synchronously driving the movable frame 604, the seal 605 and the slide bar 607 to move forward, and the contact and rolling action between the inking roller 611 and the seal 605 can realize the ink replenishing effect of the seal 605. When the slide bar 607 moves to contact the inclined surface of the inclined surface block 608, the seal 605 just moves to the front side of the ink cartridge 610. At this time, the push plate 603, the movable frame 604, the seal 605 and the slide bar 607 continue to move forward, and the sliding action between the slide bar 607 and the inclined surface of the inclined surface block 608 and the elastic action of the second spring 606 make the movable frame 604 and the seal 605 move downward, and when the seal 605 contacts the defective carton body 3, the marking effect of the defective carton body 3 can be achieved, and at this time, through the elastic effect of the second spring 606, the seal 605 produces a certain pressure on the carton body 3 to ensure the marking effect, and the push plate 603, the movable frame 604, the seal 605 and the slide bar 607 continue to move forward, and the push plate 603 can push the defective carton body 3 to move until the defective carton body 3 is separated from the transmission mechanism 2 and falls into the collection box 7 under the action of its own gravity to be collected, and the cylinder 602 contracts in time to drive the push plate 603, the movable frame 604, the seal 605 and the slide bar 607 to reset, thereby achieving the removal effect of the defective carton body 3;

[0032] The flip mechanism 8 includes a fixed plate 801, a semicircular block 802, a motor 803, a rotating box 804, a movable rod 805, a clamping plate 806, a silicone pad 807, a connecting rod 808, a movable part 809 and a third spring 810. The fixed plate 801 is fixed on the support frame 1. The fixed plate 801 is symmetrically fixed with fixed plates 801 on the left and right. The fixed plate 801 is also fixed with a motor 803. The output end of the motor 803 is fixed with a rotating box 804. The rotating box 804 bearing is connected to the fixed plate 801, and the rotating box 804 rotates 180° counterclockwise each time. , a movable rod 805 is slidably connected to the rotating box 804, a clamping plate 806 is fixed to the movable rod 805, and the length of the clamping plate 806 is less than the width of the paper box body 3, a silicone pad 807 is fixed to the clamping plate 806, the movable rod 805 is rotatably connected to one end of the connecting rod 808, and the other end of the connecting rod 808 is rotatably connected to the movable member 809, and the movable member 809 is slidably connected to the rotating box 804, and the movable member 809 contacts the semicircular block 802 to slide, and a third spring 810 is also fixed between the movable member 809 and the rotating box 804;

[0033] After the left industrial camera 502 detects one side of the carton body 3, if the carton body 3 is qualified, Figure 1-Figure 7As shown, at this time, the qualified paper box body 3 continues to move to the right under the action of the transmission mechanism 2. When the qualified paper box body 3 contacts the rotating box 804, the qualified paper box body 3 is located between the upper and lower clamping plates 806, and the rotating box 804 is driven by the motor 803 to rotate 180 degrees clockwise, thereby synchronously driving the clamping plate 806, the qualified paper box body 3 and the movable member 809 to rotate. During the rotation of the movable member 809, when the movable member 809 is separated from the semicircular block 802, at this time, under the elastic action of the third spring 810, the movable member 809 slides to the outside of the rotating box 804, and cooperates with the transmission action of the connecting rod 808, so that the upper and lower movable rods 805 move toward each other, thereby driving the clamping plate 806 to move, so that the silicone pad 807 on the clamping plate 806 contacts the qualified paper box body 3, thereby realizing the clamping and fixing effect of the qualified paper box body 3, and avoiding the qualified paper box body 3 from being turned over during the turning process. 804, the movable member 809 and the semicircular block 802 are just matched, so that the movable member 809 slides to the inside of the rotating box 804. According to the above principle, the silicone pad 807 on the clamping plate 806 is separated from the qualified carton body 3, and the clamping and fixing effect of the qualified carton body 3 is released. Moreover, since the length of the clamping plate 806 is less than the width of the carton body 3, it can be ensured that after the qualified carton body 3 is turned over, a part of the qualified carton body 3 falls on the right transmission mechanism 2. With the conveying effect of the right transmission mechanism 2, the qualified carton body 3 can be driven to continue to move to the right. With the effect of the flattening mechanism 4 and the detection mechanism 5 on the right transmission mechanism 2, the flattening and detection effect of the qualified carton body 3 can be realized, thereby realizing the double-sided detection of the carton body 3. This is the working principle of the visual inspection machine for packaging carton production.
