Description

Technical Field

[0001] The present invention relates to the technical field of labeling machines, and more particularly to an automatic labeling machine. Background Art

[0002] Currently, in the production process of computers and other electronic equipment, based on the needs of downstream customers, corresponding labels need to be affixed to the products to facilitate traceability of the product models.

[0003] During the labeling process, the label on the material strip needs to be peeled off from the base paper first, and then the peeled label is picked up by a robot and attached to the corresponding position of the product; when the existing labeling machine peels the label from the base paper, the release force on the label is not stable enough during the process of pulling the base paper, which can easily cause the label to be incompletely peeled off or the label cannot smoothly reach the specified position of the label picking table, thereby affecting the subsequent picking of the label by the robot. Summary of the invention

[0014] As a further solution of the present invention: an L-shaped lever adapted to the swing frame is rotatably mounted on the vertical plate;

[0015] When the bottom paper passes through the active rolling teeth and the driven rolling teeth, the L-shaped lever is rotated to push the end of the swing frame away from the driven rolling teeth toward the top block, so that the driven rolling teeth are separated from the active rolling teeth.

[0016] As a further solution of the present invention: a hollow portion is opened in the label picking platform, a label conveyor belt is rotatably arranged in the hollow portion, an anti-sticking coating is arranged on the belt surface of the label conveyor belt, the upper end surface of the label conveyor belt is at the same height as the upper end surface of the label stripping platform, and a conveying motor for driving the label conveyor belt is installed on one side of the label picking platform.

[0023] As a further solution of the present invention: a main airway connected to the mounting rod is provided in the suction cup, a plurality of branch airways connected to the main airway are provided on the lower end surface of the suction cup, and a plug is installed at the open end of the main airway.

[0024] Beneficial effects of the present invention:

[0025] The present invention uses a material belt pulling component to pull the material belt, passes the base paper of the material belt through the label peeling seam from top to bottom, and rolls up the base paper, pulls the base paper, and makes a sharp turn at the label peeling seam. The label will not follow the turn of the base paper due to its own stiffness, so that under the action of the release force, the label and the base paper are stably separated, and the label and the base paper are prevented from sticking together.

[0026] When the label is separated from the backing paper, the label is completely separated from the backing paper under the traction of the label conveyor belt and moves to the center of the label picking platform with the label conveyor belt, so that the subsequent label picking and placing unit can pick up the label.

[0027] When the label picking and placing unit picks up a label from the label conveyor belt, the cylinder gradually extends out, driving the first sliding frame to move horizontally toward the driving roller. At the same time, under the tension of the tensioning spring, the second sliding frame always drives the tensioning roller to move toward the side away from the driven roller, thereby ensuring that the entire label conveyor belt is in a tensioned state, so that the label gradually separates from the upper end surface of the label conveyor belt, avoiding excessive adhesion between the label and the label conveyor belt and the inability to pick up the label smoothly.

[0053] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0054] See also Figure 1 and Figure 2The present invention discloses an automatic labeling machine, comprising a cabinet 100 and a product conveying unit 200 installed on the cabinet 100, wherein a plurality of groups of label supply units 300 are arranged in the cabinet 100, a mechanical arm 400 is arranged between the product conveying unit 200 and the label supply unit 300, and a label picking and placing unit 500 is connected to the output end of the mechanical arm 400; the mechanical arm 400 drives the label picking and placing unit 500 to pick up a label 391 on the label supply unit 300 and label the product 240 on the product conveying unit 200;

[0055] See also Figure 3 and Figure 4 The label supply unit 300 includes a slide rail 310 fixed in the cabinet 100, a vertical plate 320 slidably connected to the slide rail 310, and a material belt pulling assembly disposed on the vertical plate 320, wherein the material belt pulling assembly is used to pull the material belt 390 and reel the bottom paper 392 of the peeled label 391;

[0056] See also Figure 5 The vertical plate 320 is also provided with a label stripping platform 340 and a label taking platform 350, a label stripping seam 341 is provided between the label stripping platform 340 and the label taking platform 350, a wedge-shaped surface 342 is provided at the lower end of one side of the label stripping platform 340 close to the label stripping seam 341, and an anti-stick coating is provided on the upper end surface of the label taking platform 350;

[0057] When the backing paper 392 in the material strip 390 passes through the label peeling slit 341 , the label 391 on the material strip 390 is separated from the backing paper 392 by the release force and remains on the label taking platform 350 .

[0058] Specifically, see Figure 6 , the product 240 to be labeled is conveyed forward by the product conveying unit 200; the material belt 390 is pulled by the material belt pulling component, the bottom paper 392 of the material belt 390 passes through the peeling seam 341 from top to bottom and the bottom paper 392 is rolled up, and the bottom paper 392 is pulled, and the bottom paper 392 makes a sharp turn at the peeling seam 341. The label 391 will not turn with the bottom paper 392 due to its own stiffness, so that under the action of the release force, the label 391 is separated from the bottom paper 392, and the peeled label 391 is retained on the anti-sticking layer of the label picking platform 350; then the robot arm 400 drives the label picking and placing unit 500 to pick up the label 391 on the label picking platform 350, and sticks the label 391 on the corresponding position of the product 240.

[0059] It should be noted that the stiffness of the label 391 is the key to label peeling, so the surface material is required to have a certain strength and hardness. For soft film materials, the thickness should be appropriately increased, generally controlled to be above 100μm. The stiffness of the label 391 is related to the thickness and area of ​​the material. Poor stiffness of the label 391 will cause the label 391 to be unable to be separated from the base paper 392 smoothly, making the automatic label peeling ineffective;

[0060] The release force is the force required for the label 391 to separate from the backing paper 392, which is related to the type and thickness of the adhesive and the silicon coating on the surface of the backing paper 392. If the release force is too small, the label 391 will easily fall off during transportation, while if the release force is too large, it will be difficult to separate the label 391 from the backing paper 392.

[0061] The type of the anti-stick coating is not limited, and may be silicone anti-stick agent, synthetic silica, fluorocarbon polymer, polymer or copolymer containing long-chain alkyl group, Teflon and the like.

[0062] It is worth noting that in order to meet the labeling operations of multiple specifications, the label supply units 300 can be arranged in multiple groups in a linear array. Similarly, multiple groups of material belt traction components can be distributed up and down on each label supply unit 300, so as to achieve staggered labeling and improve labeling efficiency.

[0063] In one embodiment, see Figure 3 The material strip pulling assembly includes a material strip reel 330 and a bottom paper reel 370 rotatably mounted on the vertical plate 320, and a bottom paper pulling member 360 is provided between the bottom paper reel 370 and the outlet of the label stripping station 340;

[0064] Specifically, the material tape 390 on the material tape reel 330 is pulled out and the bottom paper 392 is passed through the label peeling slit 341, and the bottom paper 392 is pulled by the bottom paper pulling member 360 to realize the peeling of the label 391 and the bottom paper 392, and the label 391 is retained on the label taking platform 350, and the bottom paper 392 is rolled up on the bottom paper reel 370;

[0065] See also Figure 6 Considering the smoothness of the traction of the material belt 390 and the bottom paper 392, a first guide roller 321 is provided between the material belt reel 330 and the label stripping platform 340, a second guide roller 322 is provided between the label stripping platform 340 and the bottom paper traction member 360, and a third guide roller 323 is provided between the bottom paper traction member 360 and the bottom paper reel 370;

[0066] First, the material tape 390 pulled out from the material tape reel 330 is guided by the first guide roller 321, so that the material tape 390 horizontally transitions to the label stripping platform 340; then, the bottom paper 392 passing through the label stripping slit 341 is guided by the second guide roller 322, and the bottom paper 392 is guided to the bottom paper traction member 360; finally, the bottom paper 392 pulled out by the bottom paper traction member 360 is guided by the third guide roller 323, so that the bottom paper 392 is smoothly wound onto the bottom paper reel 370.

[0067] For further information, see Figure 3 , Figure 4 and Figure 7 The bottom paper traction member 360 includes a driving rolling tooth 361 and a driven rolling tooth 364 meshing with each other. A traction motor 380 is also installed on the vertical plate 320. The output end of the traction motor 380 is connected to a driving gear 381. The driving rolling tooth 361 is connected to a transmission gear 382 meshing with the driving gear 381. The traction motor 380 is connected to the bottom paper roll 370 through a transmission belt 383.

[0068] Specifically, the traction motor 380 drives the driving gear 381 to rotate, and under the meshing transmission of the driving gear 381 and the transmission gear 382, ​​the active reel 361 is driven to rotate, and the driven reel 364 is also meshed and rotated accordingly, so that the bottom paper 392 passes through the meshing gap between the active reel 361 and the driven reel 364, and the active reel 361 and the driven reel 364 are used to bite and pull the bottom paper 392. At the same time, the traction motor 380 drives the bottom paper roll 370 to rotate synchronously through the transmission belt 383, so that the bottom paper 392 pulled out by the bottom paper pulling member 360 is synchronously wound onto the bottom paper roll 370.

[0069] For further information, see Figure 4 In order to ensure the traction effect of the bottom paper traction member 360 on the bottom paper 392, a sleeve rod 362 and a top block 365 are fixed to the vertical plate 320 respectively, and a swing frame 363 is rotatably sleeved on the sleeve rod 362, and the driven rolling tooth 364 is rotatably installed on the end of the swing frame 363 close to the active rolling tooth 361, and a push spring 366 is arranged between the end of the swing frame 363 away from the driven rolling tooth 364 and the top block 365;

[0070] Specifically, under the elastic force of the push spring 366, the end of the swing frame 363 away from the driven rolling tooth 364 is pushed away from the top block 365, so that the swing frame 363 rotates around the sleeve rod 362, and the end of the swing frame 363 provided with the driven rolling tooth 364 swings toward the side of the active rolling tooth 361, so that the driven rolling tooth 364 is in close contact with the active rolling tooth 361, thereby increasing the bite force of the driven rolling tooth 364 and the active rolling tooth 361 on the bottom paper 392, avoiding the bottom paper 392 from slipping during the traction process, and ensuring the stability of the traction process of the bottom paper 392.

[0071] Also, see Figure 4 In order to facilitate the bottom paper 392 to pass through the gap between the active rolling teeth 361 and the driven rolling teeth 364, an L-shaped lever 367 adapted to the swing frame 363 is rotatably installed on the vertical plate 320; when the bottom paper 392 passes through the active rolling teeth 361 and the driven rolling teeth 364, the L-shaped lever 367 is rotated to push the end of the swing frame 363 away from the driven rolling teeth 364 toward the side of the top block 365, so that the driven rolling teeth 364 are separated from the active rolling teeth 361, and the bottom paper 392 can be conveniently passed between the active rolling teeth 361 and the driven rolling teeth 364.

[0072] In another embodiment, after the label 391 and the backing paper 392 are peeled off at the label stripping station 340, the label 391 moves toward the label taking station 350 only by the feeding inertia of the material belt 390, which may easily cause the label 391 to be not centered on the label taking station 350, or even cause the label 391 to only partially contact the label taking station 350 or produce wrinkles, causing the label 391 to be scrapped; for this reason, please refer to Figure 8 and Fig. 9 The label taking platform 350 is provided with a hollow portion, in which a label conveyor belt 359 is rotatably arranged, and a non-stick coating is arranged on the belt surface of the label conveyor belt 359. The upper end surface of the label conveyor belt 359 is in the same height as the upper end surface of the label stripping platform 340. A conveying motor 3511 for driving the label conveyor belt 359 is installed on one side of the label taking platform 350;

[0073] Specifically, the label conveyor belt 359 is driven to rotate by the conveying motor 3511, so that the upper end surface of the label conveyor belt 359 moves toward the side away from the label stripping table 340. When the label 391 is separated from the base paper 392, the side of the label 391 away from the label stripping table 340 contacts the label conveyor belt 359 and adheres to the anti-sticking coating of the label conveyor belt 359. Then, the label 391 can be completely separated from the base paper 392 under the traction of the label conveyor belt 359 and moves with the label conveyor belt 359 to the center of the label picking table 350, so as to facilitate the subsequent label picking and placing unit 500 to pick up the label 391.

[0074] It should be noted that, in the process of the label picking and placing unit 500 picking up the label 391, the anti-stick coating can prevent the adhesive layer on the label 391 from sticking to the label conveyor belt 359 when the label 391 is separated from the label conveyor belt 359; and in the process of the label conveyor belt 359 pulling the label 391, the friction between the anti-stick coating and the label 391 is sufficient to drive the label 391 to move horizontally to the center position of the label picking platform 350.

[0075] For further information, see Figure 8 and Fig. 9In order to enable the label 391 to be separated from the label conveyor belt 359 smoothly, a driving roller 351 and a driven roller 352 are rotatably installed on the side of the label taking platform 350 close to the label stripping platform 340, and a first sliding frame 353 and a second sliding frame 356 are horizontally slidably installed on the side of the label taking platform 350 away from the label stripping platform 340; a telescopic roller 354 is rotatably installed on the first sliding frame 353, and a cylinder 355 for driving the first sliding frame 353 is installed on the label taking platform 350; a tensioning roller 357 is rotatably installed on the second sliding frame 356, and a tensioning spring 358 abutting against the second sliding frame 356 is provided on the label taking platform 350;

[0076] The label conveyor belt 359 is wound around the driving roller 351, the driven roller 352, the tensioning roller 357 and the telescopic roller 354 in sequence; in the horizontal direction, the tensioning roller 357 is always located on the side of the telescopic roller 354 away from the driving roller 351;

[0077] Specifically, see Fig.10 , the overall extension profile of the label conveyor belt 359 is a right-angle trapezoid, that is, the belt surface between the telescopic roller 354 and the tensioning roller 357 is always in an inclined state; before the label pick-up and place unit 500 picks up the label 391 from the label conveyor belt 359, the cylinder 355 is in a retracted state, at which time the telescopic roller 354 is located on the side away from the driving roller 351, and the label 391 is located in the area between the driving roller 351 and the telescopic roller 354;

[0078] When the label picking and placing unit 500 picks up the label 391 from the label conveyor belt 359, the cylinder 355 gradually extends out, driving the first sliding frame 353 to move horizontally toward the side of the driving roller 351, so that the belt surface length between the driving roller 351 and the telescopic roller 354 is gradually reduced. At the same time, under the tension of the tensioning spring 358, the second sliding frame 356 always drives the tensioning roller 357 to move toward the side away from the driven roller 352, so that the belt surface length between the driven roller 352 and the tensioning roller 357 is gradually increased, thereby ensuring that the entire label conveyor belt 359 is in a tensioned state. In this way, the label 391 can be gradually separated from the upper end surface of the label conveyor belt 359, avoiding that the adhesion between the label 391 and the label conveyor belt 359 is too large and the label 391 cannot be picked up smoothly.

[0079] In addition, for the picking position of the label 391, a number of through slots 3510 can be opened on the label picking platform 350 or the label conveyor belt 359, and a sensor can be installed under the label picking platform 350. When the label 391 reaches the set picking position, the sensor can sense the label 391 through the corresponding through slot 3510, thereby controlling the label conveyor belt 359 to stop feeding.

[0080] In further embodiments, see Fig.11 and Fig.12 The label placement unit 500 includes a mounting frame 510 connected to the robot arm 400, a plurality of hollow rods 520 arranged on the mounting frame 510, and an adsorbent 530 detachably connected to the hollow rods 520; the hollow rods 520 are connected to an air pipe joint 540;

[0081] See also Fig.13 The adsorbent 530 includes a connecting sleeve 531 plugged into the hollow rod 520, a mounting rod 532 detachably connected to the connecting sleeve 531, and a suction cup 533 detachably connected to the mounting rod 532;

[0082] It should be noted that the air pipe joint 540, the hollow rod 520, the connecting sleeve 531, the mounting rod 532 and the suction cup 533 are interconnected to achieve gas transmission.

[0083] For further information, see Fig.14 and Fig.15 A plurality of elastic beads 534 are circumferentially arranged on the connecting sleeve 531, and a recessed portion 535 adapted to the elastic beads 534 is circumferentially opened on the mounting rod 532; the upper end of the mounting rod 532 is inserted into the connecting sleeve 531 so that the elastic beads 534 are stuck in the recessed portion 535, thereby realizing the quick assembly of the mounting rod 532 and the connecting sleeve 531.

[0084] Also, see Fig.13 , Fig.14 and Fig.15 The suction cup 533 has a main airway 536 in communication with the mounting rod 532, and the lower end surface of the suction cup 533 has a plurality of branch airways 537 in communication with the main airway 536, and a plug 538 is installed at the open end of the main airway 536;

[0085] After the lower end surface of the suction cup 533 contacts the label 391, air is sucked through the air pipe joint 540, so that negative pressure is generated at each bronchial passage 537 to achieve adsorption of the label 391;

[0086] It should be noted that an opening is provided at one end of the main airway 536 so as to facilitate the processing of the main airway 536 . After processing and forming, the open end of the main airway 536 can be sealed by a plug 538 .
