[0038] Furthermore, in a preferred embodiment, the servo positioning and correction module 9 includes a servo motor and a push plate. The servo motor is mounted inside the frame 1 and connected to a PLC controller. The push plate is located above the roller conveyor, and the output end of the servo motor is connected to the push plate via a support plate. Furthermore, the push plate can cooperate with the positioning cylinder module 2 to push the carton to a predetermined position.
[0039] Furthermore, as a preferred embodiment, the servo motor is mounted on the side wall of the frame 1 via a motor mount.
[0040] Furthermore, as a preferred embodiment, the support plate passes through the gap between two adjacent rollers 11 and is connected to the push plate; the number of support plates can be set as needed.
[0041] The working principle of this utility model is as follows: First, the carton is placed on the roller conveyor. The carton will move along the extension direction of the roller conveyor as the roller 11 rolls. When the carton moves to the vicinity of the first labeling module 4, the carton will first contact the first position sensor on the baffle 31. The first position sensor sends a signal to the PLC controller. The PLC controller controls the servo motor to drive the push plate to move closer to the carton, so as to push the carton to move and contact the third position sensor on the first positioning cylinder 21. After the third position sensor on the first positioning cylinder 21 detects the position information of the carton, it sends the relevant signal to the PLC controller. At this time, the servo motor stops working. The baffle 31, the output end of the first positioning cylinder 21, and the push plate all abut against the outer wall of the carton to fix its position. Then, the PLC controller controls the output end of the first labeling cylinder 42 to extend towards the carton and affix the label with a QR code printed by the first printer 41 to one side of the carton. After affixing, the PLC controller controls the output end of the first labeling cylinder 42 to retract away from the carton. The PLC controller controls the output end of the positioning blocking cylinder to retract downward, thereby causing the baffle 31 to move downward and controlling the servo motor to drive the push plate to reset. The baffle 31 can enter the interior of the frame 1 through the gap between the two rollers. The carton can continue moving on the same roller conveyor to another. Due to the carton's inertia, it will move a certain distance on the other roller conveyor. Then, the stopping cylinder controls the baffle 31 to rise and extend out of the frame 1. The other roller conveyor first drives the carton to move in the opposite direction (towards the baffle 31) and contact the second position sensor on the baffle 31. The second position sensor sends a signal to the PLC controller, which then controls the servo motor to drive the pusher plate to move towards the carton, pushing it to contact the third position sensor on the second stopping cylinder 22. The third position sensor on the second stopping cylinder 22 detects the carton's position. After receiving the information, the relevant signals are sent to the PLC controller. At this time, the servo motor stops working. The output end of the baffle 31, the second positioning cylinder 22, and the push plate are all against the outer wall of the carton, thus fixing the position of the carton. Then, the PLC controller controls the output end of the second labeling cylinder 52 to extend towards the carton and affix the label with the QR code printed by the second printer 51 to one side of the carton. After affixing, the PLC controller controls the output end of the second labeling cylinder 52 to retract away from the carton and controls the servo motor to drive the push plate to reset. Then, the other roller line rotates in the opposite direction, driving the carton to move away from the baffle 31.
[0042] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
