[0037] The following describes a label stripping device 100 and a labeling apparatus according to an embodiment of the present invention with reference to the accompanying drawings.

[0038] Reference Figures 1 to 3According to a first embodiment of the present invention, a label peeling device 100 includes a fixed frame 140, a fixed assembly 170, and a label peeling assembly. The fixed assembly 170 is mounted on the fixed frame 140 and includes a first fixing member 220 and a second fixing member 200. The first fixing member 220 has a first side surface 230 and a second side surface 240 facing each other. The first side surface 230 is used to support the label paper 180, and the second fixing member 200 is used to fix the label paper 180 to the first side surface 230. The label peeling assembly includes a first driver 120, a second driver 110, and a peeling member 190. The first driver 120 is used to drive the peeling member 190 to move along the Z-axis, and the second driver 110 is used to drive the peeling member 190 to move along the Y-axis. The peeling member 190 is provided with a supporting portion 250, which is used to abut the label paper 180 to bend one end of the label paper 180 about the X-axis to the second side surface 240. This embodiment of the label peeling device 100 can improve the success rate of label 270 peeling.

[0039] Specifically, the first driver 120 and the second driver 110 can be conventional linear motors or drive cylinders in the art, as long as they can drive the stripping member 190 to move along the Z-axis and the Y-axis. The first driver 120 is mounted on the fixed frame 140, the second driver 110 is mounted on the output end of the first driver 120, and the stripping member 190 is fixed to the output end of the second driver 110. Alternatively, the second driver 110 is mounted on the fixed frame 140, the first driver 120 is mounted on the output end of the second driver 110, and the stripping member 190 is fixed to the output end of the first driver 120.

[0040] To peel the label 270 from the label paper 180, the label paper 180 is first placed on the first side 230. After adjusting the label 270 to the appropriate position, the second fixing member 200 is used to press the label paper 180 against the first side 230. The first fixing member 220 and the second fixing member 200 are then fixed relative to each other to secure the label paper 180. The first actuator 120 is then activated, driving the peeling member 190 to gradually approach and abut against the label paper 180 in the negative Z-axis direction, causing the label paper 180 to move in the negative Z-axis direction, thereby bending the label paper 180. When the upper surface of the peeling member 190 moves below the second side 240, the first actuator 120 is deactivated, and the second actuator 110 is activated, driving the peeling member 190 to move in the positive Y-axis direction, causing the label paper 180 to move in the positive Y-axis direction, thereby bending the label paper 180 to the second side 240, completing the label peeling operation.

[0041] Compared with the prior art method of only bending along the negative direction of the Z axis, bending the label paper 180 again along the positive direction of the Y axis can increase the bending angle of the label paper 180 to increase the bending force exerted on the label paper 180, thereby increasing the success rate of peeling the label 270 from the release paper, and better peeling small labels 270 and labels 270 with strong adhesion.

[0042] Reference Figure 4 According to some embodiments of the present invention, the peeling member 190 further includes a first boss 320 disposed on the upper surface of the abutting portion 250. The first boss 320 is configured to abut the label paper 180, so that a portion of the label paper 180 is closely attached to the end surface of the first fixing member 220 facing the peeling member 190. The provision of the first boss 320 enables the label paper 180 to further adhere to the first fixing member 220.

[0043] Specifically, after one end of the label paper 180 is bent around the X-axis to the second side surface 240 under the support of the supporting portion 250, the peeling member 190 continues to move along the Y-axis until the left end face of the first boss 320 abuts against the right end face of the second fixing member 200, clamping the label paper 180 between the left end face of the first boss 320 and the right end face of the second fixing member 200, so that the label paper 180 is further adhered to the first fixing member 220, ensuring the bending angle of the label paper 180, reducing the situation where the bent surface and the first fixing member 220 are not adhered due to the elasticity of the label paper 180 itself, and ensuring the peeling effect of the label peeling device 100.

[0044] Reference Figure 4 According to some embodiments of the present invention, the second side surface 240 is further provided with a first inclined surface 300, and the supporting portion 250 is further provided with a second inclined surface 310. The second inclined surface 310 is used to allow a portion of the label paper 180 to adhere to the first inclined surface 300. The provision of the first inclined surface 300 and the second inclined surface 310 further increases the bending force on the label paper 180.

[0045] Specifically, after the abutting portion 250 moves along the negative direction of the Z axis until the first inclined surface 300 and the second inclined surface 310 are aligned, the first driver 120 stops operating, and the second driver 110 drives the abutting portion 250 to move along the positive direction of the Y axis until the abutting portion 250 abuts and clamps the label paper 180 against the first inclined surface 300. Since the label paper 180 is clamped at this time, it has an effect similar to pulling and tightening, further increasing the bending force applied to the label paper 180. In addition, the provision of the first inclined surface 300 further increases the bending angle of the label paper 180 and also increases the bending force applied to the label paper 180.

[0046] According to some embodiments of the present invention, the included angle between the first inclined surface 300 and the first side surface 230 is set between 30 degrees and 60 degrees.

[0047] Specifically, the angle between the first bevel 300 and the first side surface 230 can be set to 30 degrees, 40 degrees, 45 degrees, 50 degrees or 60 degrees. When the angle between the first bevel 300 and the first side surface 230 is less than 30 degrees, although the bending angle of the label paper 180 is relatively large, due to the small angle, the supporting effect of the supporting portion 250 on the label 270 is not obvious and is easy to slip, which is not conducive to manipulation during production. When the angle between the first bevel 300 and the first side surface 230 is greater than 60 degrees, the bending angle of the label paper 180 is relatively small, and the bending force that can be increased is limited. Therefore, setting the angle between the first bevel 300 and the first side surface 230 between 30 degrees and 60 degrees has a better bending effect.

[0048] Reference Figure 3 According to some embodiments of the present invention, the abutting portion 250 is further provided with an escape groove 260, which is used to escape the label 270 on the label paper 180. The provision of the escape groove 260 makes it easier to separate the label 270 from the label paper 180.

[0049] Specifically, the shape and size of the relief groove 260 are determined by the size of the label 270 being peeled. If the abutting portion 250 lacks the relief groove 260, the abutting portion 250 and the label 270 directly contact each other, potentially damaging the label 270. By providing the relief groove 260 in the abutting portion 250, the bending force can be shifted from the right side of the label 270 to the corners of the label 270. The corners of the label 270 typically have sharp points, making it easier to separate the label 270 from the label paper 180 from the corners than to peel from the entire side of the label 270.

[0050] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the first fixing member 220 is further provided with a second boss 210. The second boss 210 is provided on the first side surface 230. The second boss 210 is used to abut against the label paper 180 to define the fixed position of the label paper 180 on the first side surface 230. The provision of the second boss 210 can improve the positioning efficiency and positioning accuracy of the label paper 180 on the first side surface 230.

[0051] Specifically, in actual production, labels 270 of the same specifications are usually printed on label paper 180 of the same specifications, that is, the dimensions of each label paper 180 are the same, and the positions of the labels 270 on the label paper 180 are also approximately the same. By providing the second protrusion 210 to abut against the label paper 180, one end of the label paper 180 is positioned at the correct peeling position when abutting against the second protrusion 210. Compared to manual alignment, this improves the efficiency and accuracy of positioning the label paper 180 on the first side surface 230.

[0052] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the fixing assembly 170 further includes a third driver 160. The third driver 160 is mounted on the fixing bracket 140. The first fixing member 220 and the second fixing member 200 are mounted on the output end of the third driver 160. The third driver 160 is used to drive the first fixing member 220 and the second fixing member 200 to move toward or away from each other. The provision of the third driver 160 can improve the efficiency of fixing and releasing the label paper 180.

[0053] Specifically, the third actuator 160 can be a conventional drive motor or drive cylinder in the art. The third actuator 160 can drive only the first fixing member 220 or the second fixing member 200 to move, or can simultaneously drive the first fixing member 220 and the second fixing member 200 toward or away from each other. By providing the third actuator 160, the label paper 180 can be automatically clamped after it is positioned on the first side surface 230, and automatically released after peeling is completed, thereby improving the efficiency of the label paper 180 fixing and releasing, making the production process more compact.

[0054] Reference Figure 1 According to some embodiments of the present invention, the fixing assembly 170 further includes a fourth actuator 130 mounted on the fixing bracket 140. The third actuator 160 is fixed to the output end of the fourth actuator 130. The fourth actuator 130 is used to drive the first fixing member 220 and the second fixing member 200 to move along the Y-axis or the X-axis. The provision of the fourth actuator 130 enables the label stripping device 100 to automatically approach the printed label paper 180.

[0055] Specifically, the fourth actuator 130 is configured to drive the first and second fixing members 220 and 200 to move along the Y-axis or the X-axis, allowing the first and second fixing members 220 and 200 to extend and retract. After the printer prints the label 270 and ejects the label paper 180, the fourth actuator 130 drives the first and second fixing members 220 and 200 toward the label paper 180. When the label paper 180 is positioned on the first side 230, the third actuator 160 drives the first and second fixing members 220 and 200 toward each other to clamp the label paper 180 to the first side 230. The fourth actuator 130 then drives the first and second fixing members 220 and 200 back to their original positions, cooperating with the peeling member 190 to perform the label peeling operation. The provision of the fourth actuator 130 enables the label peeling device 100 to automatically approach and clamp the printed label paper 180, eliminating the need for manual transfer of the label paper 180 to the first side 230, reducing labor costs and improving process efficiency.

[0056] When the fourth driver 130 is provided, the second boss 210 is provided at the same time, which can improve the positioning accuracy of the label paper 180 on the first side 230, reduce the probability of the label 270 deviating from the peeling area when the label 270 is automatically clamped, compensate for CNC errors, and further reduce the number of manual corrections.

[0057] Reference Figure 5 According to some embodiments of the present invention, the fixing assembly 170 further includes a sensor 400, which is mounted on the first fixing member 220 or the second fixing member 200. The sensor 400 is used to detect whether a label paper 180 is placed on the first side 230. The provision of the sensor 400 can further reduce manual operation and reduce the possibility of empty clamping of the first fixing member 220 and the second fixing member 200.

[0058] Specifically, the sensor 400 can be a photoelectric sensor or a visual sensor. By providing the sensor 400, it is possible to determine whether a label sheet 180 is placed on the first side 230 by observing changes in brightness or contour on the first side 230. When the first and second fixing members 220 and 200 move to the position of the label sheet 180 and the label sheet 180 is located on the first side 230, the sensor 400 senses that the label sheet 180 has reached the set position. The sensor 400 then provides a signal to the operator or control system. Upon receiving the signal, the operator or control system drives the third actuator 160 to clamp and secure the label sheet 180. After the clamping operation is completed, the fourth actuator 130 is driven to return the first and second fixing members 220 and 200 to their original peeling positions. The provision of the sensor 400 further reduces manual operation and the possibility of un-clamping the first and second fixing members 220 and 200, thereby improving the automation level of the label stripping device 100.

[0059] Reference Figure 5 According to some embodiments of the present invention, the label peeling device 100 further includes a recycling frame 430 and a fan 410. The fan 410 is disposed on one side of the first fixing member 220. The fan 410 is configured to blow the label paper 180 away from the first side surface 230 so that the label paper 180 falls into the recycling frame 430. By providing the recycling frame 430 and the fan 410, the peeled label paper 180 can be quickly recycled.

[0060] Specifically, the fan 410 is disposed on the left or right side of the first fixing member 220, with the air outlet of the fan 410 facing the first fixing member 220. After the label stripping device 100 completes the label stripping operation on the label paper 180, the first fixing member 220 and the second fixing member 200 are released to release the label paper 180. At this time, the fan 410 is turned on to blow the label paper 180 away from the first side surface 230 and into the recycling box 430 for recycling, thereby improving the recycling efficiency of the discarded label paper 180.

[0061] When the label peeling position of the first fixing member 220 is higher, a shielding cover 420 can be set on the fixing frame 140 to limit and guide the falling label paper 180 and guide the label paper 180 into the recycling frame 430 to reduce the possibility of the label paper 180 scattering.

[0062] Furthermore, a second sensor can be provided in the recycling box 430 or at the mouth of the recycling box 430. The second sensor can be selected as a through-beam sensor, an infrared sensor or the like to detect the amount of label paper 180 in the recycling box 430 to prevent the label paper 180 in the recycling box 430 from overflowing.

[0063] The labeling device according to the second embodiment of the present invention includes the label peeling device 100 of the first embodiment of the present invention, and also includes a printer and a label picking device, the printer is used to print and output label paper 180, the label picking device includes a clamp and a fifth driver 150, the fifth driver 150 is used to drive the clamp to clamp the peeled label 270.

[0064] Specifically, after the printer prints label paper 180, it secures the label paper 180 between the first securing member 220 and the second securing member 200. After the securing operation is completed, the label stripping member begins to move, peeling the label 270. After the label 270 is peeled, the fifth actuator 150 drives the clamping jaws to remove the peeled label 270 for subsequent labeling. By applying the label stripping device 100 according to the first embodiment of the present invention, the success rate of label 270 peeling can be improved, and small labels 270 and labels 270 with strong adhesion can be better peeled.

[0065] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
