Description

Technical Field

[0001] The invention relates to the technical field of label peeling machines, in particular to a label peeling machine and a working method thereof. Background Art

[0002] The label paper is transported through the label suction feeding mechanism to the transparent tape, and then the label paper and the release paper are peeled off through the label tearing action of the mechanical arm. At present, some customers require paperless production, so the label paper is cut before production, and then transported to the label tearing machine process through the product and the label paper. However, one difficulty is that the label paper has been cut. If it is to be torn off, it cannot be torn off by rolling and rewinding. Therefore, a roll of transparent tape must be used for the operation. The existing technology is that general labels are made into rolls, which cannot realize paperless processing, and the roll-type labeling can only be attached to one side of each package at a time. If multiple sides need to be labeled, the labeling process needs to be repeated, which is very inefficient. Therefore, considering that the robot arm performs multi-sided labeling, the traditional roll-type label paper cannot cooperate with the robot arm. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the invention

9. A working method of a label peeling machine, relating to a label peeling machine according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: The operator places the transparent tape onto the reel (273) through the tape roller (272), so that the middle of the transparent tape passes through the tensioning rod (276) of the tensioning cylinder (274), the pressing mechanism and the guide rod (277); Step 2: The operator places the label paper on the first conveyor belt (8). When the label paper passes the first proximity sensor (9), the rear stop cylinder (10) descends, and the label paper continues to move forward until it reaches the second conveyor belt (16). Step 3: The alignment cylinders (17) on both sides of the second frame (15) push the alignment plate (24) to adjust the label paper to the correct position on the second conveyor belt (16), and then the label suction plate (192) connected to the vacuum pump sucks air, and the label suction plate (192) is pressed down by the second lifting cylinder (193) so that the lower surface of the label suction plate (192) contacts the upper surface of the label paper, and the label paper is sucked up, and the second lifting cylinder (193) returns to its original position; Step 4: If the peeling assembly (27) on the upper surface of the third frame (26) is used, the first lifting cylinder (21) pushes the second frame (15) to rise until the upper surface of the second conveyor belt (16) is flush with the upper surface of the first support plate (275), and the sucked label paper is pushed forward through the first support plate (275) and moved to the second support plate (2710) by the horizontal push cylinder (18), and the second lifting cylinder (193) is pressed downward to connect the release paper on the lower surface of the label paper to the transparent tape; Step 5: The reel (273) drives the transparent tape and label paper forward, and after passing the rubber pressing roller (2711), the front end reaches the contact point of the second proximity sensor (279), the reel (273) stops rotating, and the suction plate at the end of the labeling robot arm presses on the frontmost label paper, driving the connection between the frontmost label paper and the next label paper to bend, and tearing off the frontmost label paper, and finally sticking it on the box body, repeating step 5 to complete the labeling of all label papers, and the peeled release paper and transparent tape move toward the reel (273) together and are wound on the reel (273).
