Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically to an automatic positioning labeling device. Background Technology

[0002] A flat labeling machine is a packaging device that automatically applies labels using adhesive. It belongs to the labeling machinery category and is widely used in industries such as food, daily chemicals, pharmaceuticals, and electronics. It is suitable for labeling flat or curved products such as cards, cartons, and bottles.

[0003] A search revealed that the patent, CN221624230U, entitled "Utility Model of a Flat Labeling Machine," includes a frame and a conveyor belt. Research and analysis revealed that while it can prevent one end of the label from lifting during use and improve the product labeling yield, it also has the following drawbacks to some extent.

[0004] For example, if it lacks auxiliary positioning function, it cannot correct tilted products caused by factors such as conveyor belt vibration and product placement deviation during the conveying process in real time, resulting in a significant decrease in labeling accuracy. Labels are prone to being crooked, offset, or even partially extending beyond the product edge, thus affecting the consistency and aesthetics of the product appearance. In order to solve the above technical problems, we have designed an automatic positioning labeling device. Utility Model Content

[0005] The purpose of this invention is to provide an automatic positioning labeling device that can correct tilted products in real time. This solves the problem that existing labeling machines cannot correct tilted products caused by factors such as conveyor belt vibration and product placement deviation during the transportation process, resulting in a significant decrease in labeling accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatically positioned labeling device, comprising a workbench, a labeling assembly bolted to the rear side of the top of the workbench, a belt conveyor bolted to the top of the workbench, a first support plate bolted to the front side of the top of the workbench, a first electric push rod bolted to the front side of the first support plate, the output end of the first electric push rod penetrating the first support plate and bolted to a movable plate, first pressure sensors bolted to both sides of the rear side of the movable plate, a calibration plate bolted to the rear side of the first pressure sensors, an infrared sensor embedded in the rear side of the calibration plate, a display screen bolted to the front side of the movable plate, and a rejection mechanism bolted to the rear side of the right side of the top of the workbench.

[0007] Preferably, the rejection mechanism includes a second support plate, the bottom of which is connected to the worktable by bolts, and a second electric push rod is connected to the rear side of the second support plate by bolts. The output end of the second electric push rod passes through the second support plate and is connected to an L-shaped plate by bolts. A bracket is riveted to the left side of the L-shaped plate, and a vision sensor is connected to the inside of the bracket by bolts.

[0008] Preferably, a third electric push rod is bolted to the front side of the top of the L-shaped plate, the output end of the third electric push rod passes through the L-shaped plate and is bolted to a second pressure sensor, and a pressure plate is bolted to the bottom of the second pressure sensor.

[0009] Preferably, a guide rod is riveted to the rear side of the L-shaped plate, and the rear end of the guide rod passes through the second support plate.

[0010] Preferably, a discharge plate is riveted to the right side of the front side of the workbench, and a discharge chute adapted to the discharge plate is opened on the right side of the front side of the belt conveyor.

[0011] Preferably, a guide plate is riveted to the left side of the correction plate, and a reinforcing rib is riveted to the bottom of the front side of the first support plate, with the bottom of the reinforcing rib riveted to the workbench.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has the advantage of positioning function through the cooperation of the first support plate, the first electric push rod, the movable plate, the first pressure sensor and the correction plate. When the belt conveyor transports the product to be labeled, the guide plate initially guides the product. The infrared sensor detects the product passing by. At this time, the external controller controls the first electric push rod to work. The output end of the first electric push rod drives the movable plate and the correction plate to move backward. The correction plate pushes the tilted product to the correct position, thereby facilitating the subsequent labeling operation.

[0014] 2. This utility model, through the cooperation of a second support plate, a second electric push rod, an L-shaped plate, a bracket, a vision sensor, a third electric push rod, a second pressure sensor, and a pressure plate, has the advantage of rejection function. After the product is labeled, the vision sensor identifies the markings on the product surface. When no marking is identified, the external controller controls the second electric push rod to work. The output end of the second electric push rod drives the L-shaped plate to move forward. The L-shaped plate pushes the product through the unloading groove to the surface of the unloading plate, thereby rejecting unqualified labeled products and preventing them from flowing into the next production process. If the labeling is detected as qualified, the external controller controls the third electric push rod to work. At this time, the pressure plate moves downward to press the markings tightly, making them adhere more tightly to the product. Attached Figure Description

[0021] Please see Figures 1-5 An automatic positioning labeling device includes a workbench 1, a labeling assembly 2 bolted to the rear side of the top of the workbench 1, a belt conveyor 3 bolted to the top of the workbench 1, a first support plate 4 bolted to the front side of the top of the workbench 1, a first electric push rod 5 bolted to the front side of the first support plate 4, the output end of the first electric push rod 5 passing through the first support plate 4 and bolted to a movable plate 6, first pressure sensors 7 bolted to both sides of the rear side of the movable plate 6, a correction plate 8 bolted to the rear side of the first pressure sensor 7, an infrared sensor 9 embedded in the rear side of the correction plate 8, a display screen 10 bolted to the front side of the movable plate 6, and a rejection mechanism 11 bolted to the rear side of the right side of the top of the workbench 1.

[0022] Please see Figure 4 and Figure 5 The rejection mechanism 11 includes a second support plate 12. The bottom of the second support plate 12 is connected to the worktable 1 by bolts. A second electric push rod 13 is connected to the rear side of the second support plate 12 by bolts. The output end of the second electric push rod 13 passes through the second support plate 12 and is connected to an L-shaped plate 14 by bolts. A bracket 15 is riveted to the left side of the L-shaped plate 14. A vision sensor 16 is connected to the inside of the bracket 15 by bolts.

[0023] Please see Figure 5A third electric push rod 17 is bolted to the front side of the top of the L-shaped plate 14. The output end of the third electric push rod 17 passes through the L-shaped plate 14 and is bolted to a second pressure sensor 18. A pressure plate 19 is bolted to the bottom of the second pressure sensor 18.

[0024] Please see Figure 4 A guide rod 20 is riveted to the rear side of the L-shaped plate 14, and the rear end of the guide rod 20 passes through the second support plate 12.

[0025] Please see Figure 1 A discharge plate 21 is riveted to the right side of the front side of the workbench 1, and a discharge chute adapted to the discharge plate 21 is opened on the right side of the front side of the belt conveyor 3.

[0026] Please see Figure 1 A guide plate 22 is riveted to the left side of the correction plate 8, and a reinforcing rib is riveted to the bottom of the front side of the first support plate 4. The bottom of the reinforcing rib is riveted to the workbench 1.

[0027] In use, this device is connected to an external power supply and controller. The external controller controls the belt conveyor 3, which transports the product to be labeled. The guide plate 22 initially guides the product, and the infrared sensor 9 detects the product passing by. At this time, the external controller controls the first electric push rod 5 to operate. The output end of the first electric push rod 5 drives the movable plate 6 and the correction plate 8 to move backward. The correction plate 8 pushes the tilted product so that the rear side of the product is in contact with the guard plate surface of the belt conveyor 3, thereby correcting the product and facilitating subsequent labeling operations. The first pressure sensor 7 monitors the pressure in real time to prevent excessive pushing force from damaging the product. Subsequently, the labeling assembly 2 applies labels to the corrected product surface. After labeling is completed... The product passes under the vision sensor 16, which identifies the markings on the product surface. If no marking is identified, the peripheral controller controls the second electric push rod 13 to work. The output end of the second electric push rod 13 drives the L-shaped plate 14 to move forward. The L-shaped plate 14 pushes the product through the unloading chute to the surface of the unloading plate 21, thereby rejecting unqualified labeled products and preventing them from flowing into the next production process. If the labeling is found to be qualified, the peripheral controller controls the third electric push rod 17 to work. The output end of the third electric push rod 17 drives the second pressure sensor 18 to move downward. The second pressure sensor 18 drives the pressure plate 19 to move downward. The pressure plate 19 moves downward to press the markings together, making them adhere more tightly to the product.

[0028] In summary, this automatic positioning labeling device, through the cooperation of the first support plate 4, the first electric push rod 5, the movable plate 6, the first pressure sensor 7, and the correction plate 8, solves the problem that existing labeling machines cannot correct tilted products caused by factors such as conveyor belt vibration and product placement deviation during the conveying process in real time, resulting in a significant decrease in labeling accuracy.
