Description

Technical Field

[0001] This utility model relates to the field of label pasting equipment technology, and more specifically, to a self-adhesive label pasting equipment with intelligent counting function. Background Technology

[0002] Self-adhesive labels are a type of waterproof and convenient label. They achieve a waterproof effect through printing with PP material. The bottom of the label is coated with adhesive. The label is pasted onto the carrier paper and can be peeled off the carrier paper to stick to the product. No glue or paste is needed, resulting in no pollution and saving labeling time. Self-adhesive labeling equipment is a key auxiliary equipment in the packaging and manufacturing industries. Its operating efficiency and counting accuracy directly affect the continuity of the production process and the stability of product quality.

[0003] Chinese Patent Announcement No. CN222081117U discloses a self-adhesive label applicator. This design incorporates a conveyor belt, a packaging box, a pressure plate, and two springs. During operation, the conveyor belt rotates, moving the packaging box so that after the self-adhesive label is applied, it contacts the inclined surface of the pressure plate, causing the pressure plate to move upwards. This upward movement compresses two springs, bringing the bottom surface of the pressure plate into contact with the top surface of the packaging box. As the packaging box continues to move, the pressure plate moves relative to the box, thus flattening the newly applied self-adhesive label. However, a drawback exists in its implementation: the applicator cannot count the number of labeled products during operation.

[0004] Therefore, a self-adhesive labeling device with intelligent counting function is proposed to address the above problems. Utility Model Content

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution uses a counting mechanism and a dual counting verification mechanism of light sensing and gravity detection to realize intelligent counting of labeled products. The light emitter and light sensor work together to trigger a counting signal when the product blocks the light. At the same time, the gravity sensor detects the weight of the product and compares the weight signal with the preset range to verify the validity of the counting signal. This dual verification mechanism can effectively eliminate counting errors caused by external stray light interference, product conveying deviation and other factors. At the same time, it can identify unqualified products with abnormal weight, avoid unqualified products from being included in the statistical data, and ensure the accuracy and reliability of the counting results.

[0018] (2) This solution, by setting an adjustment mechanism, facilitates flexible adjustment of the horizontal and vertical positions of the labeling components. It can quickly adjust the labeling position according to the size and shape differences of the products to be labeled, without disassembling and reassembling equipment parts, which greatly shortens the equipment adjustment time. This enables the equipment to complete the labeling operation of different products and improves the adaptability of the equipment to multi-variety and small-batch production scenarios.

[0030] Example 1:

[0031] Please see Figure 1 - Figure 4A self-adhesive label applicator with intelligent counting function includes a support plate 1, a support frame 2 fixedly connected to the lower end of the support plate 1, an L-shaped plate 3 fixedly connected to the upper end of the support plate 1, a hydraulic cylinder 4 fixedly connected to one side of the L-shaped plate 3, a push plate 5 fixedly connected to the output end of the hydraulic cylinder 4 via a coupling, a label applicator 6 fixedly connected to the upper end of the support plate 1, an adjustment mechanism 7 fixedly connected to the upper end of the support plate 1, and a counting mechanism 8 fixedly connected to the upper end of the support plate 1. The counting mechanism 8 includes a U-shaped plate 81. Multiple pads 82 are fixedly connected to the lower end of U-shaped plate 81. The pads 82 are fixedly installed on the upper end of support plate 1. A motor 3 83 is fixedly connected to one side of U-shaped plate 81. The output end of motor 3 83 is fixedly connected to drive roller 2 84 through a coupling. A conveyor belt 85 is rotatably connected to the outer surface of drive roller 2 84. A support roller 2 86 is rotatably connected to the inner surface of conveyor belt 85. The support roller 2 86 is fixedly installed inside U-shaped plate 81. A counting component 87 is fixedly connected inside U-shaped plate 81.

[0032] The hydraulic cylinder 4 is an HSG series engineering hydraulic cylinder, which can drive the push plate 5 to move in a straight line until the push plate 5 contacts the product to be labeled and applies stable pressure, pushing the product toward the labeling component 79 to complete the labeling operation.

[0033] Motor 3 83 is a Y-series three-phase asynchronous motor, which can provide power for the operation of conveyor belt 85. It drives drive roller 2 84 to rotate through the coupling. Drive roller 2 84 drives conveyor belt 85 to run by friction with conveyor belt 85, realizing the transportation of products to be labeled and products already labeled.

[0034] The counting component 87 includes a second U-shaped plate 871, which is fixedly installed inside the first U-shaped plate 81. A pad 872 is fixedly connected to the bottom wall of the inner cavity of the second U-shaped plate 871. A gravity sensor 873 is embedded inside the pad 872. A light emitter 874 is fixedly connected to one side of the pad 872, and a light sensor 875 is fixedly connected to the other side of the pad 872. A red filter is attached to the outer surface of the light sensor 875.

[0035] The gravity sensor 873 uses an HXC series high-precision gravity sensor, which is embedded inside the pad 872 of the counting component 87. It is used to detect the weight of the labeled products passing through the counting component 87. The detected weight signal is converted into an electrical signal and sent to the PLC controller. The PLC controller compares the signal with the preset product weight range to determine whether the product is qualified: if the weight is within the preset range, the count is confirmed to be valid; if the weight exceeds the preset range, it is determined to be an abnormal product and the count is not accumulated.

[0036] The light emitter 874 is an Everlight IR204-A universal infrared light emitter, which is fixed on one side of the U-shaped plate 871 in the counting component 87. It continuously emits stable infrared light to the light sensor 875 on the opposite side, forming an infrared detection light path to provide a basic detection signal for product counting.

[0037] The light sensor 875 uses an Everlight PT204-6B universal infrared light sensor. A red filter is attached to its outer surface and fixed to the other side of the U-shaped plate 871 in the counting component 87, opposite to the light emitter 874. It is used to receive the infrared light emitted by the light emitter 874. When the labeled product passes through the counting component 87, it will block the infrared light path, and the light sensor 875 will not receive the light signal. It will then generate a trigger electrical signal and send it to the PLC controller to trigger the counting logic. The red filter on the outer surface can filter out external stray light interference, ensuring that the light sensor 875 only receives infrared light of a specific wavelength, improving the stability of the detection signal and the counting accuracy.

[0038] This solution starts the motor 83, which drives the drive roller 84 to rotate. The drive roller 84 drives the conveyor belt 85 to run through friction. The conveyor belt 85 runs smoothly under the support of the support roller 86. It can transport the products to be labeled to the labeling component 79, and at the same time transport the labeled products to the counting component 87.

[0039] When the labeled product passes through the U-shaped plate 871 of the counting component 87, it blocks the red light emitted by the light emitter 874. The light sensor 875, unable to receive the light signal, sends a trigger signal to the PLC controller. Simultaneously, after the labeled product passes through the pad 872, the gravity sensor 873 inside the pad 872 detects the product's weight and sends a weight signal to the PLC controller. When the PLC controller receives both the trigger signal from the light sensor 875 and the weight signal from the gravity sensor 873, and the weight signal is within the product's set range, it controls its integrated counter to accumulate the count. If the weight signal exceeds the preset weight range, the PLC controller determines the product as abnormal and does not accumulate the count, thus performing an intelligent counting function.

[0040] Please see Figure 5 - Figure 6The adjustment mechanism 7 includes a U-shaped frame 71, which is fixedly installed on the upper end of the support plate 1. Two slide rails 72 are fixedly connected to the inner cavity of the U-shaped frame 71. A motor 73 is fixedly connected to the upper end of the U-shaped frame 71. A lead screw 73 is fixedly connected to the output end of the motor 73 through a coupling. A moving plate 74 is threadedly connected to the outer surface of the lead screw 74. A U-shaped rod 75 is fixedly connected to one side of the moving plate 74. An internally threaded tube 76 is fixedly connected to the inner surface of the moving plate 74. A lead screw 77 is threadedly connected to the inner surface of the internally threaded tube 76. A handle 78 is fixedly connected to the outer surface of the lead screw 77. A connecting block is rotatably connected to the outer surface of the lead screw 77. A labeling component 79 is fixedly connected to the front end of the connecting block. Two guide rods are slidably connected to the inner surface of the moving plate 74.

[0041] Motor 73 is a Panasonic A6 series servo motor, which can provide power for the lateral position adjustment of the moving plate 74 in the adjustment mechanism. It drives the lead screw to rotate through the coupling, converting the rotational motion into the linear motion of the moving plate 74 along the slide rail 72, so as to realize the precise adjustment of the lateral position of the labeling component 79 and meet the labeling height position requirements of different product specifications.

[0042] The labeling assembly 79 includes a connecting strip 791, a connecting block fixedly installed on one side of the connecting strip 791, two guide rods fixedly installed on one side of the connecting strip 791, a connecting frame 792 fixedly connected to the inner surface of the connecting strip 791, a mounting frame 793 fixedly connected to the inside of the connecting strip 791 by bolts, a second motor 794 fixedly connected to the upper end of the mounting frame 793, a first drive roller 795 fixedly connected to the output end of the second motor 794 by a coupling, a labeling tape 796 rotatably connected to the outer surface of the first drive roller 795, and a first support roller 797 rotatably connected to the inner surface of the labeling tape 796.

[0043] Motor 2 794 uses a Leadshine DM542 stepper motor to provide power for the conveying of labeling tape 796. Under the coordinated action of PLC controller and stepper driver, it drives drive roller 1 795 to rotate through coupling. The friction between drive roller 1 795 and labeling tape 796 drives labeling tape 796 to run. After labeling machine 6 completes the label peeling operation, labeling tape 796 can accurately affix the label to the product surface.

[0044] This solution starts motor 73, whose output drives lead screw 1 to rotate via coupling. Since lead screw 1 is threadedly connected to moving plate 74, and moving plate 74 is slidably connected to slide rail 72 via slider, the rotation of lead screw 1 is converted into linear movement of moving plate 74 along slide rail 72 until moving plate 74 reaches the target position, thus completing the height adjustment of labeling component 79. If fine-tuning of the longitudinal position of labeling component 79 is required, the operator can manually rotate handle 78, which drives lead screw 2 77 to rotate. Since lead screw 2 77 is threadedly connected to internal threaded pipe 76, and connecting block is slidably connected to moving plate 74 via guide rod, the rotation of lead screw 2 77 is converted into linear movement of labeling component 79 along guide rod via connecting block, achieving fine-tuning of the longitudinal position of labeling component 79 and ensuring accurate matching of the labeling position to the labeling requirements of the product to be labeled.

[0045] It should be noted that the motor 3 (83), motor 1 (73), motor 2 (794), light emitter (874), light sensor (875), and gravity sensor (873) in this utility model are powered by a power supply and controlled by a PLC controller.

[0046] The PLC controller selected is a Siemens S7-200SMART series PLC, which serves as the control core of the equipment. It is responsible for receiving signals from various sensors and sending control commands to various execution components to achieve coordinated scheduling of the overall operation of the equipment. The internally integrated counter is a COUNTER type counter, which exists as a built-in functional module of the PLC controller, forming an integrated design with the PLC controller.

[0047] It should be noted that the specific installation methods, circuit connection methods, oil circuit connection methods, and control methods of motor 3 83, motor 1 73, motor 2 794, light emitter 874, light sensor 875, gravity sensor 873, and hydraulic cylinder 4 in this utility model are all conventional designs, and this utility model will not elaborate on them in detail.

[0048] Working principle:

[0049] The labeling component 79 can be adjusted to change its position. The PLC controller sends a position control command to the servo driver of motor 73 based on the target position of the moving plate 74. Upon receiving the command, the servo driver drives motor 73 to rotate. The output of motor 73 drives the lead screw to rotate via a coupling. Since the lead screw is threadedly connected to the moving plate 74, and the moving plate 74 is slidably connected to the slide rail 72 via a slider, the rotation of the lead screw is converted into linear motion of the moving plate 74 along the slide rail 72. During this movement, the servo driver continuously feeds back the actual position signal of motor 73 to the PLC controller. The controller compares the actual position with the target position. If there is a deviation, the rotation direction and angle of motor 73 are adjusted until the moving plate 74 reaches the target position, thus completing the lateral position adjustment of the labeling component 79. If fine adjustment of the longitudinal position of the labeling component 79 is required, the operator can manually rotate the handle 78. The handle 78 drives the lead screw 77 to rotate. Since the lead screw 77 is threadedly connected to the internal threaded tube 76, and the connecting block is slidably connected to the moving plate 74 through the guide rod, the rotation of the lead screw 77 is converted into the connecting block driving the labeling component 79 to move linearly along the guide rod, thereby realizing the fine adjustment of the longitudinal position of the labeling component 79 and ensuring that the labeling position accurately matches the labeling requirements of the product to be labeled.

[0050] Product conveying and labeling: The operator places the product to be labeled at the designated starting position on the support plate 1. The PLC controller, based on the set conveyor belt speed 85, controls the contactor of motor 3 83 to close, starting motor 3 83 and driving drive roller 2 84 to rotate. Drive roller 2 84 drives the conveyor belt 85 through friction. The conveyor belt 85, supported by support roller 2 86, maintains stable operation, conveying the product to be labeled towards the labeling assembly 79. When the product reaches the designated labeling position between push plate 5 and labeling belt 796, the PLC controller controls hydraulic cylinder 4 to start. The piston rod of hydraulic cylinder 4 extends, allowing push plate 5 to push the product to be labeled toward and adhere it to labeling tape 796. Simultaneously, the PLC controller sends a pulse signal to the stepper driver of motor 2 794, which drives motor 2 794 to rotate. Motor 2 794 drives drive roller 1 795 to rotate, and drive roller 1 795 drives labeling tape 796 through friction. Labeling tape 796 cooperates with label-picking plate of labeling machine 6 to peel off the label and stick it to the designated position on the product to be labeled, completing the labeling action. After labeling is completed, the PLC controller controls the piston rod of hydraulic cylinder 4 to retract, driving push plate 5 to reset.

[0051] Product Labeling Counting: Labeled products continue to be conveyed towards the counting component 87 of the counting mechanism 8 under the drive of the conveyor belt 85. When the labeled product passes through the U-shaped plate 871 of the counting component 87, it first blocks the red light emitted by the light emitter 874. Since the light sensor 875 does not receive the light signal, it sends a trigger electrical signal to the PLC controller. At the same time, after the labeled product passes through the pad 872, the gravity sensor 873 inside the pad 872 detects the weight of the product and sends a weight electrical signal to the PLC controller. When the PLC controller receives both the trigger signal from the light sensor 875 and the weight signal from the gravity sensor 873, and the weight signal is within the set range of the product, it will control the internal integrated counter to accumulate the count. If the weight signal exceeds the preset weight range, the PLC controller determines that the product is an abnormal product and does not accumulate the count, thus achieving the function of intelligent counting. By repeating the above labeling and counting process, the same product can be continuously labeled.

[0052] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
