Description

Technical Field

[0001] The utility model belongs to the field of packaging, and in particular relates to an acoustic-magnetic labeling machine. Background Art

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

[0003] Currently, there are two ways to label acoustic magnetic labels. One is manual labeling, which involves peeling the label off the separation backing paper manually and then sticking it on the goods or other items that need protection. The other is machine labeling, which involves sucking the label with a suction cup, peeling the label off the separation backing paper, and using a carrying mechanism to stick the label sucked by the suction cup on the goods or other items that need protection.

[0004] Both of the above methods have the problem of low labeling efficiency. In addition, in existing machine labeling, the separation and pasting of labels are located at two positions. After the label is separated from the label backing paper, it needs to be moved to the position where the label needs to be pasted, and the process is relatively cumbersome. Utility Model Content

[0010] A plurality of guide shafts and tension rings are arranged between the unwinding wheel and the label stripping blade. The tension ring is located at the lowest position, and the label belt passes under the tension ring. An elastic tension scraper is arranged on one side of the guide shaft located at the highest position, and the tension scraper is used to press the label belt onto the adjacent guide shaft.

[0016] The push head and the push head driving mechanism are arranged on the mounting plate, and the upper part of the mounting plate is provided with a left limit block and a right limit block with mirror-image structures, and the left limit block and the right limit block are located on both sides of the push head; the outer edges of the opposite end surfaces of the upper parts of the left limit block and the right limit block are provided with baffles to serve as label baffles. When the push head is in the lowest position, the upper ends of the left limit block and the right limit block are higher than the push head, forming a label space for accommodating the separated acoustic and magnetic labels.

[0017] The lower parts of the left limit block and the right limit block are rotatably mounted on the mounting plate, and a section of roller track is respectively arranged on the opposite sides of the left limit block and the right limit block, and the bottom of the roller track is a recessed part. A roller is respectively arranged on 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 roller track, so that the left limit block and the right limit block are rotated and separated to both sides; reset springs are respectively arranged between the upper parts of the left limit block and the right limit block and the mounting plate, so that the left limit block and the right limit block are reset when the push head moves downward.

[0020] The beneficial effect of the utility model is as follows: the utility model utilizes the difference between the acoustic magnetic label and the label tape, and adopts a label peeling blade with a special label peeling angle, so that when the label tape in a tensioned state passes over the label peeling blade, the harder acoustic magnetic label automatically rises to a certain height, and is attracted by the negative pressure hole of the push head to adhere to the push head, and then the push head moves the acoustic magnetic label up and sticks it to the product above. Therefore, the utility model can realize the tensioning of the label tape, the automatic peeling of the acoustic magnetic label, and the sticking of the acoustic magnetic label through the continuous action of winding and unwinding, effectively improving the labeling efficiency of the acoustic magnetic label.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0033] Embodiment 1: refer to the attached Figure 1-2 As shown, an acoustic magnetic label labeling machine includes a labeling machine working part 1 and a labeling machine base 2, a screw lifting mechanism 10 is arranged on the labeling machine base 2, a 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, and the fixed plate of the labeling machine working part 1 is fixedly connected to the slider, so that the height of the labeling machine working part 1 can be adjusted by rotating the hand wheel at the end of the screw.

[0034] Continue to refer Figure 1 , 2 A discharge wheel 15 and a reel wheel 12 are arranged on the front of the fixed plate of the working part 1 of the labeling machine. The label roll 3 to be used is installed on the discharge wheel 15, and the reel wheel 12 is used to reel in the label tape roll 4 after the label is peeled off.

[0035] The back side of the fixed plate of the working part 1 of the labeling machine is provided with an unwinding servo module 14 and a rewinding servo module 13 for controlling 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 accurately control the peeling length of the acoustic magnetic label.

[0036] like Figure 1 , 3As shown, a label peeling and pasting mechanism is arranged at the edge of the front side of the fixed plate of the working part 1 of the labeling machine. The label peeling and pasting mechanism includes a mounting plate perpendicular to the fixed plate. A peeling knife plate 7 fixed on the fixed plate is arranged above the mounting plate. The front end of the peeling knife plate 7 is provided with a peeling angle of less than 15°. The peeling angle of this embodiment is 11-12°. A gap is left between the peeling knife plate 7 and the mounting plate for the label tape to pass through. A push head 18, a crank push rod 17 and a push head servo module 8 are arranged on the mounting plate. 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 linearly up and down, thereby driving the push head 18 to move linearly up and down.

[0037] When the label stripping blade 7 strips the acoustic magnetic label on the label tape 100, the label tape 100 on both sides of the label stripping angle needs to be tightened. Therefore, the following structure is adopted: Figure 1 , 8 As shown, the front side of the fixed plate of the working part 1 of the labeling machine is also provided with a guide shaft 29, a tensioning ring 9, a label band clamping mechanism 5 and a tensioning scraper 6, through which the label band 100 on the upper and lower sides of the stripping corner is tensioned.

[0038] like Figure 8 As shown, the guide shaft 29 is provided with a plurality of, the tensioning ring 9 is provided with a single, the tensioning ring 9 is slidably provided in a vertical slide groove on the fixed plate, and is connected to the tensioning ring counterweight 16 provided on the back of the fixed plate, as shown in FIG. Figure 2 A tensioning scraper 6 is also provided on one side of the top guide shaft 29. The tensioning scraper 6 is rotatably mounted on the mounting column of the fixed plate through a torsion spring. With the elastic force of the torsion spring, the tensioning scraper 6 is pressed against the label belt 100. This structural design can tension the label belt 100 below the stripping blade 7.

[0039] The label tape clamping mechanism is as follows Fig.10 As shown, it includes a first pressing wheel 32 and a second pressing wheel 33, which are respectively installed on corresponding wheel axles; one end of a pressing rod 34 is rotatably connected to the wheel axle of the second pressing wheel 33, and the other end is provided with a groove. When the groove is stuck on the wheel axle 36 of the first pressing wheel 32, the first pressing wheel 32 and the second pressing wheel 33 as well as the label tape 100 with the label removed passing between the two pressing wheels can be pressed; when the pressing rod 34 is lifted, a gap is generated between the first pressing wheel 32 and the second pressing wheel 33 for the label tape 100 to pass through. After the label tape 100 with the label removed passes between the two pressing wheels, the two pressing wheels are pressed by the pressing rod 34.

[0040] A synchronous belt mechanism 11 is provided on the back of the fixed plate of the working part 1 of the labeling machine, including a synchronous wheel 35, a synchronous belt 37 and a friction plate 38. The synchronous wheel 35 is installed on the wheel shaft 36 of the first pressure wheel 32 to drive the first pressure wheel 32 to rotate; the friction plate 38 is installed on the wheel shaft of the winding wheel 12, and the synchronous belt 37 is installed on the output end of the synchronous wheel 35, the friction plate 38 and the winding servo module 13. When the winding servo module 13 is working, it is driven by the synchronous belt 37 to drive the winding wheel 12 and the first pressure wheel 32 to rotate synchronously to pull the label tape 100 to be wound.

[0041] The label roll 3 installed on the unwinding wheel 15 leads out the label tape 100 with the acoustic magnetic label, and is guided by the guide shaft 29, passes around the tensioning ring 9 from below the tensioning ring 9, and then is guided by the top guide shaft 29 and pressed by the tensioning scraper 6, passes around the stripping angle of the stripping blade 7 from bottom to top, and then passes between the first pressure wheel 32 and the second pressure wheel 33, and finally is wound on the winding wheel 12. In this way, the tensioning scraper 6 can tighten the label tape 100 below the stripping blade 7, and the label tape 100 above the stripping blade 7 can be tightened after the two pressure wheels are pressed. Since the acoustic magnetic label has a certain thickness and hardness compared to the label tape, the acoustic magnetic label will automatically rise from the label tape 100 when it passes the smaller stripping angle, so that the push head 18 can push the raised acoustic magnetic label upward and stick it on the product.

[0042] Further, such as Figure 5 As shown, the end surface of the push head 18 facing the label stripping blade 7 is provided with a negative pressure hole 21 and an optical fiber detection hole 22. The stripped acoustic magnetic label can be adsorbed through the negative pressure hole 21, and whether the acoustic magnetic label is adsorbed on the push head 18 can be detected through the optical fiber detection hole 22. When the acoustic magnetic label is detected on the push head 18, the push head servo module 8 drives the crank push rod 17 and the push head 18 to move linearly upward, and the acoustic magnetic label on the push head 18 is attached to the product.

[0043] In the utility model, the crank structure in the crank push rod has the characteristics of the highest position and the lowest position in the circular motion, so that the push head pushes the mark more stably.

[0044] In other embodiments, a servo electric cylinder and a push rod may be used to replace the push head servo module and the crank push rod, which can also play the role of driving the push head to move up and down in a straight line.

[0045] Example 2: Figure 3 As shown, on the basis of embodiment 1, further, a left limit block 19 and a right limit block 20 are respectively arranged on both sides of the push head 18, and the two limit blocks are respectively rotatably mounted on the mounting plate, and a space for the push head 18 to move up and down is provided between the two limit blocks. The structures of the left limit block 19 and the right limit block 20 are mirror images, as shown in FIG. Figure 6, 7 As shown, a raceway 27 is provided on one side of any limit block toward the push head 18, and a recess is provided at the bottom of the raceway 27; a baffle is provided on the outer edge of the end surface opposite to the upper part of the left limit block 19 and the right limit block 20, as a label baffle 25, to prevent the acoustic magnetic label from exceeding the push head; a spring baffle 26 is also provided on the left limit block 19 and the right limit block 20, and after the left limit block 19 is rotatably mounted on the mounting plate, a left return spring 23 is provided between the spring baffle 26 and the mounting plate, and similarly, a right return spring 24 is provided between the spring baffle 26 of the right limit block 20 and the mounting plate. The elastic force of the two return springs can keep the label baffles 25 of the left and right limit blocks against the sides of the push head 18 respectively.

[0046] Further, if Fig. 9 As shown, the left and right sides of the push head 18 are respectively provided with a left roller 30 and a right roller 31, the left roller 30 rolls along the roller track 27 on the left limit block 19, and the right roller 31 rolls along the roller track 27 on the right limit block 20. A recessed portion is provided at the lower part of the roller track 27. In the initial state, the left roller 30 and the right roller 31 fall into the recessed portions of the corresponding roller track 27 respectively. When the push head 18 moves upward, the rollers on both sides roll upward along the roller track 27, pushing the left and right limit blocks to both sides, so that the push head 18 can stick the label on the product.

[0047] like Figure 8 As shown, in the initial state, the push head 18 is in the lowest position, and the top ends of the left limit block 19 and the right limit block 20 are higher than the top end of the push head 18. Therefore, the left limit block 19, the right limit block 20 and the push head 18 form a label space 28 for accommodating the peeled acoustic magnetic label, and the label space 28 is located in front of the peeling knife plate 7.

[0048] The movement direction of the push head can be constrained by setting the limit block to ensure the push head to move up and down in a straight line. At the same time, the label space formed by the limit block and the push head can also ensure the accurate position of the label.

[0049] Embodiment 3: A labeling method using the labeling machine described in Embodiment 2 comprises the following steps:

[0050] Step 1, installation of label roll and tensioning of label tape: install the label roll 3 with the acoustic magnetic label on the unwinding wheel 15, manually pull out the label tape 100 and pass it around the guide shaft 29 and the tensioning ring 9, and then pass it around the label stripping blade 7, pass it through the first pressing wheel 32 and the second pressing wheel 33, and fix it on the winding wheel 12, close the pressing rod 34, and ensure that the tensioning scraper 6 presses the label tape 100 on the adjacent guide shaft 29, at this time, the label tape 100 is in a tensioned state;

[0051] Step 2: The reeling servo module 13 and the unreeling servo module 14 work simultaneously to pull the label roll. When the label tape 100 passes through the label peeling blade 7, the acoustic magnetic label is separated from the label tape 100 due to the label peeling angle. The separated acoustic magnetic label is located in the label space 28 and is adsorbed by the negative pressure hole 21 on the push head 18 and adhered to the push head 18.

[0052] Step three, after the optical fiber detection hole 22 on the push head 18 detects that there is an acoustic magnetic label on the push head 18, the push head servo module 8 is started, driving the crank push rod 17 to move upward, driving the push head 18 to move upward, and during the upward movement, the rollers on both sides of the push head 18 push the right limit block 20 and the left limit block 19 to separate. When the crank push rod 17 runs to the highest position, the push head 18 will move the acoustic magnetic label to the upper product and stick it on the product, and at the same time disconnect the negative pressure of the negative pressure hole 21 on the push head 18, so that the push head 18 is separated from the stuck acoustic magnetic label;

[0053] Step 4: As the push head servo module 8 continues to operate, the crank push rod 17 moves from the highest position to the lowest position. When the crank push rod 17 returns to the lowest position, a labeling cycle is completed;

[0054] Step 5: Repeat steps 2, 3, and 4 to complete the labeling of the acoustic magnetic label.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
