Description

Technical Field

[0001] This invention belongs to the field of packaging, specifically relating to an acousto-magnetic label applicator and a labeling method. Background Technology

[0002] In the packaging industry, acousto-magnetic (AM) tags are electronic anti-theft tags that use the principle of magnetic field induction to prevent theft. They are affixed to the outer packaging of products to serve an anti-theft function.

[0003] Currently, there are two methods for acousto-magnetic (AM) labeling: one is manual labeling, where the label is peeled off from the backing paper and then affixed to the product or other item that needs protection; the other is machine labeling, where a suction cup holds the label, peels it off from the backing paper, and then a conveyor mechanism affixes the label held by the suction cup to the product or other item that needs protection.

[0004] Both of the above methods suffer from low labeling efficiency. Moreover, with existing machine labeling, the separation and application of the label occur in two separate locations. After the label is separated from the label backing paper, it still needs to be moved to the location where it needs to be labeled, which is a rather cumbersome process. Summary of the Invention

[0005] The purpose of this invention is to provide an acousto-magnetic label applicator and a labeling method that realizes continuous actions of unwinding the label roll, peeling off the label, pasting the label, and rewinding the label backing paper, thereby improving the labeling efficiency of acousto-magnetic labels.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: an acousto-magnetic label applicator, comprising a label applicator working part and a label applicator base, wherein the label applicator working part is mounted on the label applicator base, and the label applicator working part includes: The unwinding reel is used to mount the label roll to be used. The unwinding reel is driven to rotate by the unwinding servo module. The take-up reel is used to take up the label tape after the label has been removed. The take-up reel is driven to rotate by the take-up servo module. The label peeling blade has a peeling angle of less than 15° at its front end. When the label tape with the acousto-magnetic label passes around the peeling angle from bottom to top, the acousto-magnetic label separates from the label tape. The pusher head and the pusher head drive mechanism are connected to the lower part of the pusher head, which drives the pusher head to move up and down in a linear motion. The upper surface of the pusher head is provided with a negative pressure hole and an optical fiber detection hole. Several guide shafts and tensioning rings are provided between the unwinding roller and the label peeling blade. The tensioning rings are located at the lowest point, and the label tape passes under the tensioning rings. An elastic tensioning scraper is provided on one side of the guide shaft at the highest point. The tensioning scraper is used to press the label tape onto the adjacent guide shaft. A label tape clamping mechanism is provided between the label peeling blade and the winding wheel to tension the label tape above the label peeling blade.

[0007] The pusher drive mechanism includes a pusher servo module and a crank pusher. The output shaft of the pusher servo module drives the crank pusher to move up and down. The upper end of the crank pusher is connected to the lower end of the pusher.

[0008] The pusher drive mechanism includes a servo electric cylinder and a push rod. The servo electric cylinder is connected to the lower end of the push rod, and the upper end of the push rod is connected to the lower end of the pusher.

[0009] The peeling angle of the label-stripping blade is 11-12°.

[0010] The tensioning ring slides along the vertical groove on the working part of the labeling machine, and a tensioning ring counterweight is connected to the tensioning ring.

[0011] The pusher and pusher drive mechanism are mounted on the mounting plate. The upper part of the mounting plate is provided with a left limiting block and a right limiting block that are mirror images of each other. The left limiting block and the right limiting block are located on both sides of the pusher. The outer edges of the opposite end faces of the upper part of the left limiting block and the right limiting block are provided with baffles to serve as label baffles. When the pusher is in the lowest position, the upper ends of the left limiting block and the right limiting block are higher than the pusher, forming a label space to accommodate the separated acousto-magnetic label.

[0012] The lower parts of the left and right limiting blocks are rotatably mounted on the mounting plate. A raceway is provided on the opposite sides of the left and right limiting blocks, and the bottom of the raceway is a recessed part. A roller is provided on each of the left and right sides of the push head. When the push head moves from bottom to top, the rollers on both sides roll along the raceway, causing the left and right limiting blocks to rotate and separate to the sides. A return spring is provided between the upper part of the left and right limiting blocks and the mounting plate, so that when the push head moves downward, the left and right limiting blocks return to their original positions.

[0013] The label tape clamping mechanism includes a first pressure roller, a second pressure roller, and a pressure rod. The first and second pressure rollers are respectively mounted on corresponding axles, and a gap is left between the first and second pressure rollers for the label tape after the acousto-magnetic label is removed to pass through. One end of the pressure rod is rotatably mounted on the axle of the second pressure roller, and the other end is provided with a groove that can be engaged on the axle of the first pressure roller. When the pressure rod is engaged on the axle of the first pressure roller, the first and second pressure rollers clamp the label tape. The axle of the first pressure roller is connected to the axle of the take-up roller through a synchronous belt mechanism.

[0014] The labeling machine base is equipped with a screw lifting mechanism for adjusting the height of the working part of the labeling machine.

[0015] This invention further proposes an acousto-magnetic labeling method, wherein the acousto-magnetic labeling machine described in this method includes the following steps: Step 1: Install the label roll with the acousto-magnetic label on the unwinding wheel, manually pull out the label tape and pass it around the guide shaft and tension ring, then around the label peeling blade, and through the label tape clamping mechanism to fix it on the take-up wheel. At this time, the label tape is in a tensioned state. Step two: The take-up servo module and the unwind servo module work simultaneously to pull the label roll. When the label tape passes the label peeling blade, the acousto-magnetic label is peeled off and attracted by the negative pressure hole on the pusher head, adhering to the pusher head. Step 3: After the fiber optic detection hole on the pusher head detects the acousto-magnetic label on the pusher head, the pusher head driving mechanism moves the pusher head to the highest position, attaches the acousto-magnetic label to the product, and at the same time disconnects the negative pressure of the negative pressure hole on the pusher head, so that the pusher head separates from the attached acousto-magnetic label. Step four: The pusher drive mechanism moves the pusher from the highest position to the lowest position, completing one labeling cycle; Step 5: Repeat steps 2 through 4 to complete the acousto-magnetic labeling process.

[0016] The beneficial effects of this invention are as follows: This invention utilizes the difference between acousto-magnetic labels and label tapes, employing a peeling blade with a special peeling angle. As the taut label tape passes over the peeling blade, the harder acousto-magnetic label automatically rises to a certain height and is attracted by the negative pressure of the pusher head's negative pressure holes, adhering to the pusher head. The pusher head then moves the acousto-magnetic label upwards and adheres it to the product above. Therefore, this invention, through continuous winding and unwinding actions, can achieve label tape tensioning, automatic peeling of the acousto-magnetic label, and acousto-magnetic label adhesion, effectively improving the labeling efficiency of acousto-magnetic labels.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the invention in any way.

[0029] Example 1: Refer to Appendix Figure 1-2 As shown, an acousto-magnetic label applicator includes a working part 1 and a base 2. A screw lifting mechanism 10 is provided on the base 2. The slider of the screw lifting mechanism 10 is connected to the screw, and the slider is also slidably sleeved on the guide rods on both sides of the screw. The fixing plate of the working part 1 is fixedly connected to the slider. Thus, rotating the handwheel at the end of the screw can adjust the height of the working part 1.

[0030] Continue to refer to Figure 1 , 2 On the front of the fixed plate of the working part 1 of the labeling machine, there are unwinding rollers 15 and rewinding rollers 12. The label rolls 3 to be used are installed on the unwinding rollers 15, and the rewinding rollers 12 are used to rewind the label tape rolls 4 after the labels have been peeled off.

[0031] The back of the fixing plate of the labeling machine working part 1 is provided with an unwinding servo module 14 and a rewinding servo module 13 that control the rotation of the unwinding wheel 15 and the rewinding wheel 12. Both the unwinding servo module 14 and the rewinding servo module 13 are servo motors, which can precisely control the peeling length of the acousto-magnetic label.

[0032] like Figure 1 , 3 As shown, a label peeling and pasting mechanism is provided on the edge of the front side of the fixed plate of the labeling machine working part 1. The label peeling and pasting mechanism includes a mounting plate perpendicular to the fixed plate. A label peeling blade 7 is fixed on the fixed plate above the mounting plate. The front end of the label peeling blade 7 is provided with a peeling angle of less than 15°. In this embodiment, the peeling angle is 11-12°. A gap is left between the label peeling blade 7 and the mounting plate for the label tape to pass through. The mounting plate is provided with a push head 18, a crank push rod 17, and a push head servo module 8. The lower end of the crank push rod 17 is connected to the push head servo module 8, and the upper end is connected to the push head 18. The push head servo module 8 drives the crank push rod 17 to move up and down linearly, thereby driving the push head 18 to move up and down linearly.

[0033] When the label peeler 7 peels off the acousto-magnetic label from the label strip 100, the label strip 100 on both sides of the peeling angle needs to be tensioned. Therefore, the following structural configuration is adopted: Figure 1 , 8 As shown, the front of the fixing plate of the labeling machine working part 1 is also provided with a guide shaft 29, a tensioning ring 9, a label tape clamping mechanism 5 and a tensioning scraper 6, which tension the label tape 100 on the upper and lower sides of the label peeling corner.

[0034] like Figure 8 As shown, multiple guide shafts 29 are provided, and one tensioning ring 9 is provided. The tensioning ring 9 is slidably disposed in a vertical groove on the fixed plate and is connected to a tensioning ring counterweight 16 provided on the back of the fixed plate, as shown. Figure 2 As shown. A tensioning scraper 6 is also provided on one side of the uppermost guide shaft 29. The tensioning scraper 6 is rotatably mounted on the mounting post of the fixed plate via a torsion spring. With the help of the torsion spring's elasticity, the tensioning scraper 6 presses firmly onto the label tape 100. This structural design can tension the label tape 100 below the label peeler plate 7.

[0035] The label tape clamping mechanism is as follows Figure 10As shown, it includes a first pressure roller 32 and a second pressure roller 33, which are respectively mounted on corresponding axles; one end of the pressure rod 34 is rotatably connected to the axle of the second pressure roller 33, and the other end is provided with a groove. When the groove is engaged with the axle 36 of the first pressure roller 32, it can press the first pressure roller 32 and the second pressure roller 33, as well as the label strip 100 that passes through the two pressure rollers and has its label removed, together; when the pressure rod 34 is lifted, a gap is created between the first pressure roller 32 and the second pressure roller 33 for the label strip 100 to pass through. After the label strip 100 with its label removed passes through the two pressure rollers, the pressure rod 34 presses the two pressure rollers together again.

[0036] The labeling machine's working part 1 has a timing belt mechanism 11 on its back side, including a timing pulley 35, a timing belt 37, and a friction plate 38. The timing pulley 35 is mounted on the axle 36 of the first pressure roller 32, driving the first pressure roller 32 to rotate. The friction plate 38 is mounted on the axle of the take-up roller 12. The timing belt 37 is mounted on the output end of the timing pulley 35, the friction plate 38, and the take-up servo module 13. When the take-up servo module 13 is working, it drives the take-up roller 12 and the first pressure roller 32 to rotate synchronously through the timing belt 37, so as to pull the label tape 100 to be taken up.

[0037] The label roll 3, mounted on the unwinding reel 15, leads out a label strip 100 with an acousto-magnetic label. Guided by the guide shaft 29, it passes under the tensioning ring 9, then, guided by the uppermost guide shaft 29 and pressed by the tensioning scraper 6, it passes from bottom to top around the peeling angle of the peeling blade 7, then passes between the first pressure roller 32 and the second pressure roller 33, and finally winds onto the take-up reel 12. In this way, the tensioning scraper 6 can tighten the label strip 100 below the peeling blade 7, and the two pressure rollers can tighten the label strip 100 above the peeling blade 7. Because the acousto-magnetic label has a certain thickness and hardness compared to the label strip, when the acousto-magnetic label passes over a small peeling angle, it will automatically lift off the label strip 100, making it easier for the pusher head 18 to push the lifted acousto-magnetic label upwards and stick it onto the product.

[0038] Furthermore, such as Figure 5 As shown, the pusher head 18 has a negative pressure hole 21 and an optical fiber detection hole 22 on its end face facing the label peeling blade 7. The negative pressure hole 21 can attract the acousto-magnetic label to be peeled off, and the optical fiber detection hole 22 can detect whether an acousto-magnetic label is attracted on the pusher head 18. When an acousto-magnetic label is detected on the pusher head 18, the pusher head servo module 8 drives the crank push rod 17 and the pusher head 18 to move upward in a linear motion, sticking the acousto-magnetic label on the pusher head 18 onto the product.

[0039] In this invention, the crank structure in the crank push rod has the characteristics of having the highest and lowest positions during circular motion, which makes the pusher and the pointer more stable.

[0040] In other embodiments, a servo cylinder and push rod can be used instead of the push head servo module and crank push rod, which can also drive the push head to move linearly up and down.

[0041] Example 2: As Figure 3 As shown, based on Embodiment 1, a left limiting block 19 and a right limiting block 20 are further provided on both sides of the push head 18. The two limiting blocks are rotatably mounted on the mounting plate, and the space between the two limiting blocks provides room for the push head 18 to move up and down. The structures of the left limiting block 19 and the right limiting block 20 are mirror images of each other. Figure 6 , 7 As shown, a raceway 27 is provided on the side of any limiting block facing the pusher head 18, and a recess is provided at the bottom of the raceway 27; baffles are provided on the outer edges of the opposite upper end faces of the left limiting block 19 and the right limiting block 20, serving as label guard edges 25 to prevent the acousto-magnetic label from exceeding the pusher head; spring stops 26 are also provided on the left limiting block 19 and the right limiting block 20. After the left limiting block 19 is rotatably mounted on the mounting plate, a left return spring 23 is provided between the spring stop 26 and the mounting plate. Similarly, a right return spring 24 is provided between the spring stop 26 of the right limiting block 20 and the mounting plate. The elastic force of the two return springs can keep the label guard edges 25 of the left and right limiting blocks abutting against the sides of the pusher head 18.

[0042] Furthermore, such as Figure 9 As shown, the push head 18 has a left roller 30 and a right roller 31 on its left and right sides, respectively. The left roller 30 rolls along the raceway 27 on the left limiting block 19, and the right roller 31 rolls along the raceway 27 on the right limiting block 20. The raceway 27 has a recessed portion at its lower part. In the initial state, the left roller 30 and the right roller 31 fall into the recessed portion of their respective raceways 27. When the push head 18 moves upward, the rollers on both sides roll upward along the raceways 27, pushing the left and right limiting blocks open to the sides, making it easier for the push head 18 to attach the label to the product.

[0043] like Figure 8 As shown, in the initial state, the pusher 18 is in the lowest position, and the tops of the left limiting block 19 and the right limiting block 20 are higher than the top of the pusher 18. Therefore, the left limiting block 19, the right limiting block 20 and the pusher 18 form a tag space 28 to accommodate the peeled acousto-magnetic tag. The tag space 28 is located in front of the tag peeling blade 7.

[0044] The setting of the limiting block can constrain the movement direction of the pusher, ensuring that the pusher moves in a straight line up and down. At the same time, the label space formed by the limiting block and the pusher can also ensure the accurate position of the label.

[0045] Example 3: Based on Example 2, the labeling method includes the following steps:

[0046] Step 1, Label roll installation and label tape tensioning: Install the label roll 3 with the acousto-magnetic label on the unwinding wheel 15, manually pull out the label tape 100 and pass it around the guide shaft 29 and tensioning ring 9, then around the label peeling blade 7, and through the first pressure roller 32 and the second pressure roller 33, and fix it on the take-up wheel 12. Close the pressure rod 34 and ensure that the tensioning scraper 6 presses the label tape 100 tightly on the adjacent guide shaft 29. At this time, the label tape 100 is in a tensioned state.

[0047] Step 2: The winding servo module 13 and the unwinding servo module 14 work simultaneously to pull the label roll. When the label tape 100 passes the label peeling blade 7, the acousto-magnetic label is separated from the label tape 100 due to the peeling angle. The separated acousto-magnetic label is located in the label space 28 and is attracted by the negative pressure hole 21 on the push head 18 and adheres to the push head 18.

[0048] Step 3: After the fiber optic detection hole 22 on the pusher head 18 detects the acoustomagnetic label on the pusher head 18, the pusher head servo module 8 is started, driving the crank push rod 17 to move upward, which in turn drives the pusher head 18 to move upward. During the upward movement, the rollers on both sides of the pusher head 18 push the right limit block 20 to separate from the left limit block 19. When the crank push rod 17 reaches the highest position, the pusher head 18 will move the acoustomagnetic label to the product above and stick it on the product. At the same time, the negative pressure of the negative pressure hole 21 on the pusher head 18 is disconnected, so that the pusher head 18 is separated from the sticked acoustomagnetic label.

[0049] Step 4: As the pusher servo module 8 continues to operate, the crank pusher 17 moves from the highest position to the lowest position. When the crank pusher 17 returns to the lowest position, one labeling cycle is completed.

[0050] Step 5: Repeat steps 2, 3, and 4 to complete the acousto-magnetic label application.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of the present invention with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are within the protection scope of the pending claims.
