Description

Technical Field

[0001] This utility model relates to the field of labeling equipment technology, specifically to a labeling device with adjustable labeling angle. Background Technology

[0002] In the food, pharmaceutical, electronics, and daily chemical manufacturing industries, the labeling process is a key link in product packaging and information labeling. Its labeling accuracy, efficiency, and adaptability directly affect the product appearance quality, the accuracy of information transmission, and the overall production line capacity.

[0003] Most traditional labeling equipment can only achieve single-angle labeling and lacks an automatic rotation adjustment mechanism. When faced with the need for tilted or circumferential labeling, the angle of the nozzle or product clamp must be manually adjusted. This is not only cumbersome and time-consuming, but also has low accuracy due to low precision. It is easy to cause inconsistent labeling angles due to operational errors. Moreover, the nozzles of existing labeling equipment are mostly fixed structures. On the one hand, they lack stable negative pressure supply and air path control design, which can easily lead to problems such as label detachment or air bubbles and wrinkles during labeling. On the other hand, the up-and-down movement and angle adjustment of the nozzle cannot be linked. It cannot adaptively adjust according to the label feeding height when picking up the label, and it cannot fine-tune the angle according to the curvature of the product surface when labeling, resulting in problems with label flatness and adhesion.

[0004] Secondly, the conveying mechanism of traditional labeling equipment mostly relies on simple conveyor belt drive, lacking product positioning and arrival detection mechanism, and some equipment does not have blocking positioning components, so the product is prone to deviation due to inertia during the conveying process; although some are equipped with detection elements, their coordination with the conveying rhythm is poor, and it is impossible to confirm in real time whether the product has accurately arrived at the labeling station, resulting in front-back and left-right deviations in the labeling position.

[0005] To address this issue, we designed an adjustable labeling angle labeling device. Summary of the Invention

[0006] The purpose of this invention is to provide a labeling device with an adjustable labeling angle to solve the problems mentioned in the background art.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The up-and-down movement of the nozzle is driven by a motor that rotates the first drive wheel, which in turn drives the first driven wheel via a belt to raise and lower the Z-axis slider and the nozzle air rod on the Z-axis air rod mounting base. This, combined with the air nozzle connector, provides negative pressure to allow the nozzle body to pick up and apply labels, preventing labels from falling off or generating air bubbles. Simultaneously, a rotary motor drives a second drive wheel to rotate, which in turn drives the second driven wheel inside the mounting base via a belt. This, combined with the nozzle air rod, allows the nozzle body to rotate, adapting to tilted or circumferential labeling requirements.

[0019] 2. After the photoelectric sensor body on the photoelectric sensor fixing plate detects the signal of the product to be labeled, it feeds back to the control system to trigger the blocking cylinder body, which drives the blocking connector to extend and block the product, preventing the product from deviating due to inertia and ensuring that it stops accurately at the labeling processing position.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-11 This utility model provides a technical solution: an adjustable labeling angle labeling device, including a frame 1, on which a mounting plate 2 is fixed; a conveying mechanism 3, a label feeder 4, and a Y-axis moving mechanism 5 are fixed on the mounting plate 2. The conveying mechanism 3 is used to transport the product to be labeled to the processing position, and the label feeder 4 is used to provide labels; an X-axis moving mechanism 7 is connected to the Y-axis moving mechanism 5, and the X-axis moving mechanism 7 can slide back and forth along the guide rail of the Y-axis moving mechanism 5 to adjust the longitudinal position of the label; a Z-axis labeling mechanism 6 is connected to the X-axis moving mechanism 7, and the Z-axis labeling mechanism 6 can slide left and right along the guide rail of the X-axis moving mechanism 7. The Z-axis labeling mechanism 6 is provided with a suction mechanism with a suction nozzle body 625, which can move up and down and rotate to pick up labels, adjust the label angle, and complete the labeling action.

[0039] In practice, the conveying mechanism 3 transports the product to be labeled to the processing station, and the label feeder 4 provides the label; the Y-axis moving mechanism 5 carries the X-axis moving mechanism 7 to achieve longitudinal sliding, and the X-axis moving mechanism 7 carries the Z-axis labeling mechanism 6 to achieve lateral sliding. The suction nozzle mechanism on the Z-axis labeling mechanism 6 can simultaneously complete the up-and-down movement and rotation, thereby realizing the automated process of conveying, label picking, angle adjustment and labeling.

[0040] See Figure 1-11 The Y-axis moving mechanism 5 includes a left fixed base column 51 and a right fixed base column 52 fixed on the left and right sides of the mounting plate 2. A left fixed crossbeam 53 is fixed to the upper end of the left fixed base column 51, and a right fixed crossbeam 54 is fixed to the upper end of the right fixed base column 52. A front limit photoelectric sensor 64 and a rear limit photoelectric sensor 65 are fixed to the front and rear of the left fixed crossbeam 53, respectively. A left guide rail 62 is fixed on the left fixed crossbeam 53, and a left slider 63 is slidably mounted on the left guide rail 62. A left connector 66 is fixed on the left slider 63, and a front light shield 67 and a rear light shield 68 are fixed to the front and rear of the left connector 66, respectively. The front light shield 67 cooperates with the front limit photoelectric sensor 64, and the rear light shield 68 cooperates with the rear limit photoelectric sensor 65 to limit the forward and backward movement distance of the Y-axis moving mechanism 5.

[0041] In practice, the left fixed base column 51 and the right fixed base column 52 of the Y-axis are fixed on both sides of the mounting plate 2, supporting the left fixed crossbeam 53 and the right fixed crossbeam 54 of the Y-axis. When the left slider 63 of the Y-axis on the left guide rail 62 drives the left connecting piece 66 to slide, the front light shield 67 and the rear light shield 68 of the Y-axis on the left connecting piece 66 will move with the slider. When the light shield blocks the front limit photoelectric sensor 64 or the rear limit photoelectric sensor 65 of the Y-axis, the sensor triggers a signal to stop the Y-axis movement, thereby limiting the forward and backward movement distance.

[0042] See Figure 1-11 The X-axis moving mechanism 7 includes an X-axis grooved crossbeam 71 fixed on the left connecting member 66 and the right connecting member 59. An X-axis left limit photoelectric sensor 78 and an X-axis right limit photoelectric sensor 77 are fixed to the left and right sides of the X-axis grooved crossbeam 71, respectively. X-axis guide rails 75 are fixed to the upper and lower ends of the X-axis grooved crossbeam 71, and an X-axis slider 76 is slidably mounted on the X-axis guide rails 75.

The X-axis left light-shielding plate 607 cooperates with the X-axis left limit photoelectric sensor 78, and the X-axis right light-shielding plate 608 cooperates with the X-axis right limit photoelectric sensor 77, used to limit the left and right movement distance of the X-axis moving mechanism 7.

[0043] In practice, the X-axis grooved crossbeam 71 is fixed on the left connector 66 and the right connector 59. The left X-axis limit photoelectric sensor 78 and the right X-axis limit photoelectric sensor 77 on its left and right sides cooperate with the left X-axis light shield 607 and the right X-axis light shield 608 on both sides of the protective cover 606 on the Z-axis fixed plate 601. When the X-axis slider 76 drives the Z-axis labeling mechanism 6 to slide along the X-axis guide rail 75, the light shield blocks the sensor and triggers a stop signal, limiting the lateral movement range.

[0044] See Figure 1-11 The Z-axis labeling mechanism 6 has a Z-axis fixed plate 601 with a Z-axis guide rail 602, a Z-axis slider 603 slidably mounted on the Z-axis guide rail 602, a Z-axis light shield 619 fixed on the Z-axis slider 603, and a suction nozzle mechanism connected to the Z-axis slider 603. The Z-axis upper limit photoelectric sensor 604 and the Z-axis lower limit photoelectric sensor 605 are fixed on the left side of the Z-axis fixed plate 601. The Z-axis light shield 619 cooperates with the Z-axis upper limit photoelectric sensor 604 and the Z-axis lower limit photoelectric sensor 605 to detect the movement position of the Z-axis slider 603, thereby limiting the vertical movement range of the suction nozzle mechanism.

[0045] In practice, the X-axis grooved crossbeam 71 is fixed on the left connector 66 and the right connector 59. The left X-axis limit photoelectric sensor 78 and the right X-axis limit photoelectric sensor 77 on its left and right sides cooperate with the left X-axis light shield 607 and the right X-axis light shield 608 on both sides of the protective cover 606 on the Z-axis fixed plate 601. When the X-axis slider 76 drives the Z-axis labeling mechanism 6 to slide along the X-axis guide rail 75, the light shield blocks the sensor and triggers a stop signal, limiting the lateral movement range.

The lower end of the suction nozzle air rod 621 is fixed to the suction nozzle body 625 through the suction nozzle connecting shaft 624. It is used to drive the suction nozzle air rod 621 and the suction nozzle body 625 to move up and down through the suction nozzle up and down moving motor 614 and belt 617. At the same time, the air source is connected through the air nozzle connector 620 to provide negative pressure to the suction nozzle body 625, so as to realize the action of picking up the label from the label feeder 4 and labeling the product.

[0047] In practice, the up-and-down movement motor 614 drives the drive wheel 615 to rotate, which in turn drives the driven wheel 616 to rotate synchronously via the belt 617, thereby driving the Z-axis air rod fixing seat 618 on the Z-axis slider 603 to move along the Z-axis; the air rod 621 of the suction nozzle passes through the fixing seat, and the air nozzle connector 620 at its upper end is connected to the air source to provide negative pressure, while the lower end is fixed to the suction nozzle body 625 via the suction nozzle connecting shaft 624.

The lower end of the suction rod 621 is installed in the mounting hole of the driven shaft 2. It is used to drive the belt drive of the rotary motor 626 to drive the suction rod 621 and the suction body 625 to rotate, so as to realize the adjustment of the labeling angle and adapt to the labeling needs of products with different shapes.

[0049] In practice, the rotary motor 626 is fixed on the Z-axis fixing plate 601, driving the second drive wheel 627 to rotate, which in turn drives the second driven wheel 628 in the fixed base body 630 to rotate via the second belt 629; the lower end of the suction nozzle air rod 621 is installed in the mounting hole of the second driven wheel 628, and its suction nozzle air rod positioning plane 622 is matched with the positioning plane of the mounting hole to ensure rotation synchronization; at the same time, the suction nozzle air rod ridge surface 623 is matched with the bearing in the Z-axis air rod fixing base 618 to prevent the suction nozzle body 625 from rotating on its own.

An X-axis lead screw nut 74 is mounted on the X-axis lead screw 73, and the X-axis lead screw nut 74 is linked with the X-axis slider 76. It is used to drive the X-axis lead screw 73 to rotate through the X-axis motor 79, thereby driving the X-axis slider 76 and the Z-axis labeling mechanism 6 to move left and right along the X-axis guide rail 75 to adjust the lateral position of the label.

[0053] In practice, the X-axis motor 79 is fixed on the motor mounting base inside the X-axis slotted crossbeam 71, and its rotating shaft is connected to the front end of the X-axis lead screw 73 through the X-axis coupling; both ends of the X-axis lead screw 73 are fixed inside the X-axis rotating mounting base 72, and the X-axis lead screw nut 74 on it is linked with the X-axis slider 76; when the motor drives the lead screw to rotate, the nut drives the slider to slide smoothly along the X-axis guide rail 75, thereby realizing the lateral position adjustment of the Z-axis labeling mechanism 6.

The rotating shaft of the Y-axis motor 58 is connected and fixed to the front end of the Y-axis lead screw 56 through a Y-axis coupling. The two ends of the Y-axis lead screw 56 are respectively fixed in the Y-axis rotating mounting base 55. The Y-axis rotating mounting base 55 is fixed to the upper end of the right fixed base column 52 of the Y-axis. A Y-axis lead screw nut 57 is mounted on the Y-axis lead screw 56, and the Y-axis lead screw nut 57 is linked with the right connecting piece 59. The right connecting piece 59 is fixed on the right slider 61 of the Y-axis. The right slider 61 of the Y-axis is slidably mounted on the right guide rail 60 of the Y-axis. The right guide rail 60 of the Y-axis is fixed on the right fixed crossbeam 54 of the Y-axis. It is used to drive the Y-axis lead screw 56 to rotate through the Y-axis motor 58, thereby driving the left slider 63 of the Y-axis, the right slider 61 of the Y-axis, and the X-axis moving mechanism 7 to move back and forth along the Y-axis guide rail to adjust the longitudinal position of the label.

[0055] In practice, the Y-axis motor 58 is fixed on the motor mounting base at the upper end of the right fixed base column 52 of the Y-axis, and the rotating shaft is connected to the front end of the Y-axis lead screw 56 through the Y-axis coupling; both ends of the Y-axis lead screw 56 are fixed in the Y-axis rotating mounting base 55, and the Y-axis lead screw nut 57 on it is linked with the right connecting piece 59; the right connecting piece 59 is fixed on the right slider 61 of the Y-axis, and slides synchronously with the left slider 63 of the left Y-axis along the right guide rail 60 and the left guide rail 62 of the Y-axis, driving the X-axis grooved crossbeam 71 to move longitudinally.

[0056] See Figure 1-11 The Z-axis labeling mechanism 6 also has a camera mounting plate 610 fixed on the Z-axis mounting plate 601, a camera connecting plate 609 fixed on the camera mounting plate 610, and a camera 611 fixed on the camera connecting plate 609. The Z-axis mounting plate 601 also has a light source mounting plate 612 fixed on it, and a light source body 613 fixed on it. The light source body 613 is used to supplement light and cooperate with the camera 611 to identify the labeling position of the product to be labeled.

[0057] In practice, the light source fixing plate 612 on the Z-axis fixing plate 601 fixes the light source body 613 to provide supplementary light for the product to be labeled; the camera fixing plate 610 and the camera connecting plate 609 fix the camera 611 to capture the product labeling area in real time, identify the labeling position deviation, and feed back the signal to the control system to adjust the X-axis moving mechanism 7, the Y-axis moving mechanism 5 and the nozzle rotation mechanism to correct the labeling position and angle.

[0058] Working principle: Before use, all electrical appliances inside and outside this device need to be connected to an external power source, or a battery pack needs to be installed in an area outside this device that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0059] In use, the conveyor mechanism 3 fixed on the mounting plate 2 works, and the conveyor belt driven component 31 on the conveyor belt fixing plate 32 rotates to transport the product to be labeled from the feeding end to the labeling processing position. When the product approaches the processing position, the photoelectric sensor body 37 on the photoelectric sensor fixing plate 36 detects the product signal and feeds the signal back to the control system. The control system synchronously triggers the blocking cylinder body 34, and the blocking cylinder body 34 drives the blocking connector 35 to extend upward and block the product from the front of the product conveying direction, so that the product stops at the preset labeling processing position and avoids deviation due to inertia.

[0060] Subsequently, the Y-axis motor 58 on the right fixed base column 52 rotates, driving the Y-axis lead screw 56 to rotate through the coupling; the Y-axis lead screw nut 57 drives the right connecting piece 59 to slide along the right Y-axis guide rail 60, while the left Y-axis left slider 63 slides synchronously along the left Y-axis guide rail 62, jointly driving the X-axis grooved crossbeam 71 to move towards the label feeder 4. During the movement, if the Y-axis front light shield 67 or the Y-axis rear light shield 68 on the left connecting piece 66 blocks the Y-axis front limit photoelectric sensor 64 or the Y-axis rear limit photoelectric sensor 65, the Y-axis front limit photoelectric sensor 64 or the Y-axis rear limit photoelectric sensor 65 will be triggered to stop, preventing overtravel collision;

[0061] After the X-axis crossbeam is in position, the X-axis motor 79 inside the X-axis slotted crossbeam 71 rotates, driving the X-axis lead screw 73 to rotate via the coupling; the X-axis lead screw nut 74 drives the X-axis slider 76 to slide along the X-axis guide rail 75, thereby driving the Z-axis labeling mechanism 6 to move towards the label output port. During the movement, if the X-axis left light shield 607 and X-axis right light shield 608 on both sides of the protective cover 606 block the X-axis left limit photoelectric sensor 78 or the X-axis right limit photoelectric sensor 77, the X-axis left limit photoelectric sensor 78 or the X-axis right limit photoelectric sensor 77 will be triggered to stop, ensuring that the Z-axis mechanism stops directly above the label;

[0062] The nozzle-moving motor 614 on the Z-axis fixed plate 601 rotates, driving the drive wheel 615 to rotate. Through belt 617, it drives the driven wheel 616 to rotate synchronously, driving the Z-axis slider 603 to descend along the Z-axis guide rail 602, thereby bringing the nozzle air spring 621 and nozzle body 625 closer to the label. During descent, if the Z-axis light-shielding plate 619 blocks the Z-axis lower limit photoelectric sensor 605, the nozzle-moving motor 614 stops. After the nozzle body 625 reaches its position, the air nozzle connector 620 opens the negative pressure valve, providing a stable negative pressure to the nozzle body 625 to adsorb the label.

[0063] After labeling, the light source body 613 on the light source fixing plate 612 provides supplemental light, and the camera 611 on the camera connection plate 609 captures the product labeling area and transmits the image to the control system.

[0064] If tilting or wrapping labeling is required, the rotary motor 626 on the Z-axis fixed plate 601 rotates, driving the second drive wheel 627 to rotate; through the second belt 629, it drives the second driven wheel 628 in the fixed base body 630 to rotate; the suction nozzle air rod 621 rotates with the second driven wheel 628, driving the suction nozzle body 625 to rotate.
