Description

Technical Field

[0001] This invention relates to the field of flat labeling technology, specifically a fully automatic double-head flat labeling machine. Background Technology

[0002] A flat labeling machine is an industrial automated packaging equipment specifically designed for automatically affixing labels to the surfaces of various flat or slightly curved products. It belongs to the labeling machinery category, and its core function is to replace traditional manual labeling through automation.

[0003] Existing flat labeling machines typically use sensors to continuously monitor the position of the product to be labeled and feed the signal back to the PLC control system in real time. The system then precisely drives the label feeding mechanism, causing the label tape to automatically separate from the backing paper due to a sharp turn at the peeling plate. The separated label is then precisely applied to the designated surface of the product by rollers or suction heads. The entire process is coordinated by the control system to achieve continuous, high-speed, and high-precision automated labeling operations.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that existing flat labeling machines, limited by single-station or simple mechanical structures, often rely on manual assistance in step-by-step operation or secondary positioning when products need to be labeled on multiple sides, making it difficult to meet the continuous high-speed production needs of assembly lines. Summary of the Invention

[0005] This invention provides a fully automatic dual-head flat labeling machine, which solves the problem of products being unable to be labeled on multiple sides, and achieves the effect of labeling different parts of the product or two sides of the same product.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a fully automatic double-head flat labeling machine, comprising a cabinet, a human-machine interface installed on one side of the cabinet, a conveying mechanism installed inside the cabinet, a label adjustment mechanism installed inside the cabinet, and a labeling mechanism installed on one side of the label adjustment mechanism, wherein two sets of the label adjustment mechanism and the labeling mechanism are provided. The label adjustment mechanism moves in a straight line perpendicular to the cabinet along the labeling mechanism. The human-machine interface is used for human-machine dialogue and parameter adjustment.

[0007] By adopting the above technical solutions, the compact layout of the dual workstations significantly reduces the ineffective waiting area on the conveyor line, ensuring that in high-speed continuous operation, the phenomenon of missed or empty labeling caused by the delay of equipment return action is eliminated, and the material flow balance rate of the entire production line is significantly improved.

[0008] Preferably, the labeling mechanism includes a mounting plate, a feeding mechanism rotatably connected to one side of the mounting plate, a brake mounted on one side of the mounting plate, a roller and a label pressing mechanism rotatably connected to one side of the mounting plate, an photoelectric sensor frame mounted on the other side of the mounting plate, a label peeling plate mounted on the bottom of the mounting plate, a traction mechanism mounted on one side of the mounting plate, and a receiving mechanism mounted on one side of the mounting plate.

[0009] Preferably, the header adjustment mechanism includes left and right adjustment rods, which are disposed on the top of the cabinet. Up and down adjustment rods are fixedly connected to the top of the left and right adjustment rods, and front and rear adjustment rods are disposed outside the up and down adjustment rods.

[0010] Preferably, a centering mechanism is fixedly connected to the top of the cabinet, a flipping mechanism is fixedly connected to one side of the centering mechanism, the centering mechanism includes a power component, a guide component is fixedly connected to the output end of the power component, an adaptive component is fixedly connected inside the guide component, and a guide conveyor belt is fixedly connected to one side of the guide component.

[0011] Preferably, the power assembly includes a mounting bracket, and an electric actuator is mounted on the top of the mounting bracket.

[0012] Preferably, the guiding assembly includes an outer block, which is fixedly connected to an electric push rod. A guide rod is fixedly connected inside the outer block, and an inner slider is fixedly connected to the output end of the guide rod. One side of the inner slider is fixedly connected to the guide conveyor belt.

[0013] Preferably, the adaptive component includes a pressure chamber, which is fixedly connected to the inside of the external block. A piston block is slidably connected inside the pressure chamber. One side of the piston block is fixedly connected to an inner slider. One side of the pressure chamber is connected to an air pipe, and one end of the air pipe is connected to a pressure sensor.

[0014] Preferably, the flipping mechanism includes a movable component and an abutting component, and the movable component and the abutting component are fixedly connected.

[0015] Preferably, the active component includes a motor frame, which is fixedly connected to one side of the external block. A servo motor is mounted on one side of the motor frame, and the output end of the servo motor is fixedly connected to a rotating rod through the motor frame.

[0016] Preferably, the abutting assembly includes an abutting tube, which is fixedly connected inside the rotating rod. An abutting piston is slidably connected inside the abutting tube. An abutting rod is fixedly connected to one side of the abutting piston. One side of the abutting tube is connected to the other end of the air tube.

[0017] By adopting the above technical solution, when the inner slider is displaced due to clamping products of different widths, the minute change in the air chamber volume is immediately converted into a quantifiable differential air pressure signal, which is then transmitted to the pressure sensor in real time through a precision air tube. This, in conjunction with the power component, enables the product to be positioned in the center.

[0018] This invention provides a fully automatic dual-head flat labeling machine. It has the following advantages: 1. This invention achieves dual-station collaborative labeling operation by setting up two sets of label adjustment mechanisms and two sets of labeling mechanisms. Compared with the traditional single-station or manual assistance labeling method, the dual-station design can simultaneously label different parts of the product or two sides of the same product, effectively improving labeling efficiency. At the same time, the two sets of labeling mechanisms can be configured with different types of labels to meet diverse labeling needs. The dual-station design makes the labeling process more reasonable and compact, ensuring that all products on the production line are labeled and avoiding omissions.

[0019] 2. This invention achieves adaptive clamping and centering of the product to be labeled by setting an adaptive component in the centering mechanism. Precise positioning can be achieved without manual forced edge application. The piston block in the pressure chamber moves with the inner slider, and the air pressure change is transmitted to the pressure sensor through the air pipe, providing real-time feedback on the clamping force. Compared with the defects of the prior art that requires manual adjustment or forced edge application to ensure positioning, the closed-loop feedback of the pressure sensor can automatically adjust the clamping force and centering position according to the product size, achieving adaptive centering clamping for products of different specifications. This ensures that the product is always in the center position of the conveyor belt during the conveying process, avoiding labeling deviation caused by product offset and improving labeling accuracy.

[0020] 3. This invention achieves fully automatic double-sided labeling by setting up air circuit linkage between the flipping mechanism and the centering mechanism, in conjunction with two sets of labeling mechanisms. This produces a synergistic effect. Compared with the independent control of clamping and flipping in traditional labeling equipment, the adaptive clamping and flipping actions are interconnected. After the product is accurately positioned in the first labeling process, the labeled product is immediately flipped without the need for additional sensor triggering or manual intervention. The flipped product is then labeled on the reverse side by the second set of labeling mechanisms. This, in conjunction with the first set of labeling mechanisms, achieves fully automatic labeling on both sides of the product. At the same time, it provides a stable attitude reference for the flipping action, ensuring that the reverse labeling after flipping also maintains high precision. Attached Figure Description
