[0002] In modern industrial production, the use of labels is ubiquitous. Whether it is product identification, tracking or promotion, it is inseparable from the precise labeling process. Labels are usually made of a base paper and a label body bonded together by adhesive. According to different application scenarios and label characteristics, the form of labels can be divided into two types: sheet and roll. Among them, roll labels have been widely used in automated production lines due to their continuity and ease of automated processing.

[0044] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] See also Figures 1 to 13 As shown, the present invention provides a label peeling mechanism, which includes: a driving part 21; a peeling part 22, the peeling part 22 is located on the conveying path of the label 30 to be peeled off, one end of the driving part 21 is drivingly connected to the peeling part 22 to drive the peeling part 22 to move along a first direction, and the peeling part 22 has a bearing surface for bearing the label 30 to be peeled off; and a guiding part 23, the guiding part 23 is located on the recovery path of the label base paper, part of the label base paper is wound on the guiding part 23, and the guiding part 23 is constructed to be able to move synchronously with the peeling part 22.

[0046] In this embodiment, the first direction refers to the conveying direction of the label 30 to be peeled off at the position of the carrying surface. The peeling section 22 is located on the conveying path of the label 30 to be peeled off, and the portion of the label 30 to be peeled off that is conveyed to the position of the peeling section 22 is carried by the carrying surface. The guide section 23 is located on the recycling path of the label backing paper. The portion of the label backing paper after the label is peeled off is wound around the guide section 23 and guided to the location of the subsequent label backing paper recycling device through the guide section 23. Figure 4 As shown, the label is in an unpeeled state. At this time, the label 30 to be peeled does not move and is in a static state, that is, the label 30 to be peeled is relatively static with the carrying surface. When the peeling operation is performed, the label taking mechanism 70 moves to the position of the label 30 to be peeled, and fixes the label 30 to be peeled by adsorption or a material taking pad with a certain viscosity. Then, the driving part 21 drives the peeling part 22 to move along the first direction toward the driving part 21. Since the guide part 23 and the peeling part 22 move synchronously, at this time, the guide part 23 and the peeling part 22 move synchronously and pull the label backing paper to separate the label from the label backing paper. As can be seen from the above, in the process of peeling the label, the position of the label 30 to be peeled does not change, and the peeling part 22, the guide part 23 and the label backing paper are displaced. Compared with the labeling device of the prior art, in the process of taking the label, the label is slowly torn off the backing paper by the label taking mechanism 70. The position of the label of the present application does not change during the peeling process, which can effectively prevent the displacement of the label during the peeling process, thereby significantly improving the labeling accuracy.

[0047] In one embodiment of the present invention, the driving portion 21 is drivingly connected to the guiding portion 23 to drive the guiding portion 23 to move synchronously with the stripping portion 22 along the first direction.

[0048] In this embodiment, the guide part 23 and the stripping part 22 are both connected to the driving part 21, and under the drive of the driving part 21, the two can achieve synchronous movement. This setting can simplify the control logic of the equipment, reduce the control requirements for multiple independent moving parts, and reduce the design complexity and cost of the control system.

[0049] In one embodiment, the driving part 21 can be a double-acting cylinder, and the piston rod of the cylinder extends from both ends of the cylinder. When moving, one end of the piston rod gradually moves away from the center of the cylinder, and the other end gradually approaches the center of the cylinder; or, the driving part 21 can also include two electric push rods and a synchronous controller, one of the electric push rods is used to drive the stripping part 22, and the other electric push rod is used to drive the guide part 23. The two electric push rods achieve synchronous movement through the synchronous controller, thereby enabling the stripping part 22 and the guide part 23 to achieve synchronous movement.

[0053] In this embodiment, the first telescopic structure 212 is movably arranged on the driving body 211 along the first direction. Since the first mounting seat 221 is connected to the end of the first telescopic structure 212 away from the guide portion 23, the first mounting seat 221 can be moved along the first direction. Since the bearing platform 223 is arranged on the first mounting seat 221, the bearing platform 223 can be moved along the first direction. Along the second direction, the bearing platform 223 has a first side and a second side that are arranged opposite to each other. The first side of the bearing platform 223 is provided with a limiting baffle 82, and the limiting structure 222 is arranged on the second side of the bearing platform 223.

[0059] In this embodiment, the first guide roller 2261 guides and supports the label backing paper, and the second guide roller 2262 and the far end of the carrier 223 form a material transfer channel 413. The label backing paper after the label is peeled off passes through the material transfer channel 413 and reaches the position of the first guide roller 2261. The first guide roller 2261 supports and guides the label backing paper to ensure that the label backing paper can smoothly reach the guide portion 23. Through the cooperation of the first guide roller 2261 and the second guide roller 2262, a continuous guide path is formed to ensure that the label backing paper can smoothly reach the guide portion 23.

[0062] In this embodiment, the label backing paper at the position where the label 30 to be peeled is located is located on the side where the tip is away from the first mounting seat 221, and the label backing paper from which the label has been peeled is located on the side where the tip is close to the first mounting seat 221. Under the support of the tip, the label backing paper forms a sharp angle, and the edge of the end of the tip away from the driving part 21 is used as the starting point for the label and the label backing paper to begin to separate, so that the driving part 21 drives the peeling part 22 and the guide part 23 to move synchronously along the first direction away from the tip and pull the label backing paper, so that the label and the label backing paper begin to separate at the edge of the tip position.

The function of the clamping structure 42 is to stably clamp the labels 30 to be peeled off after the identification unit 41 completes the positioning of the labels 30 to be peeled off, so that the conveying of the labels 30 to be peeled off is suspended. Through the above-mentioned setting, the discharge length of the labels 30 to be peeled off can be accurately controlled. After the feeding is in place, the clamping structure 42 clamps the labels 30 to be peeled off, and the feeding process ends.

[0069] See also Figures 1 to 13 As shown, in one embodiment of the present invention, the identification part 41 includes a main structure 411 and a sensor device 412 arranged on the main structure 411, the main structure 411 has a feed channel 413, the label 30 to be peeled off can pass through the feed channel 413, and the sensor device 412 is arranged toward the label 30 to be peeled off.

[0070] In this embodiment, the sensor device 412 on the main structure 411 is set toward the label 30 to be peeled off to identify the positioning mark on the label 30 to be peeled off and accurately control the discharge length. The feed channel 413 provides a conveying path for the label 30 to be peeled off.

[0071] In one embodiment, the sensing device 412 uses an optical fiber counter-radiation sensor.

The first clamping plate 422 is fixedly connected to the second mounting seat 10, and the second clamping plate 423 is drivingly connected to the third driving structure 421. The third driving structure 421 can drive the second clamping plate 423 to move toward or away from the first clamping plate 422 to clamp or release the label 30 to be peeled off. The third driving structure 421 is in communication connection with the optical fiber counter-radiation sensor.

[0072] The optical fiber counter-beam sensor includes a transmitter and a receiver. The transmitter is used to generate and emit a light beam. When the light beam directly reaches the receiver from the transmitter without obstruction, the receiver will generate a signal indicating that the light beam path is continuous. The transmitter and the sensor are respectively arranged on opposite sides of the material passage 413. When the label 30 to be peeled enters the material passage 413, the label 30 to be peeled is located between the transmitter and the sensor. The positioning mark on the label 30 to be peeled is a through hole 31. When the label 30 to be peeled with the through hole 31 moves to the light beam path of the optical fiber counter-beam sensor, the light beam will pass through the through hole 31 and continue to be received by the receiver. At this time, the optical fiber counter-beam sensor will generate a control signal, so that the third driving structure 421 drives the second clamping plate 423 to move in the direction close to the first clamping plate 422 until the label 30 to be peeled is clamped.

When performing the peeling operation, the label taking mechanism moves to the position of the label to be peeled off, and fixes the label to be peeled off by adsorption or a material taking pad with a certain viscosity, and then the driving part drives the peeling part to move along the first direction toward the driving part. Since the guiding part and the peeling part move synchronously, at this time, the guiding part and the peeling part move synchronously and pull the label backing paper to separate the label from the label backing paper. In the process of peeling the label, the position of the label to be peeled off does not change, and the displacement occurs in the peeling part, the guiding part and the label backing paper. Compared with the labeling device of the prior art, in the process of taking the label, the label is slowly torn off the backing paper by the label taking mechanism. The position of the label of the present application does not change during the peeling process, which can effectively prevent the displacement of the label during the peeling process, thereby significantly improving the labeling accuracy.
