Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically a labeling machine with a mislabeling alarm. Background Technology

[0002] A labeling machine is an automated device primarily used to accurately affix labels to product surfaces or packaging. It completes its operation through core steps such as conveying, positioning, label picking, and application, and is widely used in various industries including food, pharmaceuticals, daily chemicals, and logistics. Its working principle is as follows: after the product is conveyed to the designated position via a conveyor belt, a sensor triggers the label feeding device, the label is peeled off and picked up by a robotic arm or vacuum suction cup, and then affixed to the predetermined position on the product under set pressure. Some models also have auxiliary functions such as smoothing and detecting label position. Based on the degree of automation, labeling machines can be divided into three categories: manual, semi-automatic, and fully automatic. Among them, fully automatic models have become the mainstream choice for large-scale production due to their high efficiency and stability. Compared to manual labeling, it can significantly improve production efficiency, reduce labor costs, and ensure the consistency and standardization of label application, making it an indispensable key piece of equipment in modern packaging production lines.

[0003] Existing devices lack a ribbon detection mechanism, making it difficult for labeling machines to automatically stop when the ribbon runs out. Operators must actively observe and execute the shutdown procedure. Operators need to check the labels for batch numbers at the front of the machine to detect when the ribbon at the back of the machine is exhausted and then stop the machine to replace it. This process not only results in a significant waste of operating time but also easily leads to products without batch numbers being mixed into subsequent processes or even entering the market, causing quality incidents. In view of this, we provide a labeling machine with a mislabeling alarm. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a labeling machine with a mislabeling alarm.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a labeling machine with a mislabeling alarm, comprising a desktop, a first riser mounted on one side of the top surface of the desktop, and a second riser mounted on the other side of the desktop, an extension bracket fixedly connected to one side of the top surface of the desktop, and a linear motor fixedly connected to the center of the top surface of the extension bracket, multiple transition rollers rotatably connected to the center of the top surface of the first riser via a rotating shaft, and a damping roller fixedly connected to one side of the top surface of the first riser via a rotating shaft, a first stepper motor fixedly connected to one side of the bottom surface of the first riser, and a take-up roller fixedly connected to the output end of the first stepper motor, a relay module fixedly connected to one side of the outer wall of the first riser, and a photoelectric sensor mounted at the center of the outer wall of the relay module, a release paper peeling plate fixedly connected to one side of the top surface of the first riser, and a red and green flashing indicator light fixedly connected to the center of the top surface of the desktop.

[0006] As mentioned above, the outer wall of the damping roller is fitted with a release paper tray.

[0007] As mentioned above, release paper is sleeved on the outer wall of the multiple transition rollers, winding rollers and release paper peeling plates, and the photoelectric sensor is aligned with the movement trajectory of the release paper.

[0008] As described above, a second stepper motor is fixedly connected to one side of the bottom surface of the second heightening frame, and multiple rotating rollers are rotatably connected inside the second heightening frame via a rotating shaft. A rubber belt is sleeved on the outer wall of the multiple rotating rollers, and one end of one of the rotating rollers is fixedly connected to the output end of the second stepper motor. One side of the outer wall of the rubber belt is close to the release paper peeling plate.

[0009] As described above, a label monitor is fixedly connected to one side of the top surface of the extension bracket, and the label monitor faces the outer wall of the release paper peeling plate.

[0010] As described above, the linear motor telescopic end is bolted to a U-shaped bracket, and multiple movable rollers are rotatably connected to both sides of the U-shaped bracket via rotating shafts. The U-shaped bracket and the multiple movable rollers are all located on one side of the rubber belt.

[0011] As described above, an information processing chip is installed in the center of the relay module, and the relay module, photoelectric sensor, red and green flashing indicator light, first stepper motor, second stepper motor and linear motor are connected by wires.

[0012] Compared with existing technologies, this labeling machine with mislabeling alarm has the following advantages:

[0013] This invention uses a photoelectric sensor to monitor the movement trajectory of the release paper between the release paper tray and the transition roller, thereby monitoring the ribbon status in real time. When the ribbon on the release paper tray is exhausted, the photoelectric sensor immediately transmits the signal to the information processing chip inside the relay module. After the information processing chip quickly analyzes the signal, it sends a stop command, cutting off the power supply to the device and simultaneously causing the red and green flashing indicator lights to emit a red light to remind the operator that the ribbon inside the release paper tray has been exhausted. Thus, when the ribbon is exhausted, the machine stops operating and alerts nearby operators to prevent products without batch numbers from being mixed into subsequent processes due to ribbon exhaustion.

[0014] This invention uses a label monitor on one side of a linear motor to capture products on the labeling production line. When a product with an unlabeled or incorrectly labeled product is captured by the label monitor, the label monitor immediately sends an abnormal signal to the relay module. After the information processing chip analyzes the signal, it synchronously cuts off the conveying power of the device, pausing the unlabeled or incorrectly labeled product at the work station on the labeling production line, thereby further reducing the possibility of unlabeled or incorrectly labeled products being mixed into subsequent processes.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] 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.

[0025] like Figure 1-4As shown, this utility model provides a technical solution: a labeling machine with a mislabeling alarm, including a desktop 1, a first riser 2 installed on one side of the top surface of the desktop 1, and a second riser 3 installed on the other side of the desktop 1, an extension bracket 4 fixedly connected to one side of the top surface of the desktop 1, and a linear motor 401 fixedly connected to the center of the top surface of the extension bracket 4, multiple transition rollers 201 rotatably connected to the center of the top surface of the first riser 2 via a rotating shaft, and a damping roller 202 fixedly connected to one side of the top surface of the first riser 2 via a rotating shaft, a first stepper motor 203 fixedly connected to one side of the bottom surface of the first riser 2, and a take-up roller 204 fixedly connected to the output end of the first stepper motor 203, a relay module 205 fixedly connected to one side of the outer wall of the first riser 2, and a photoelectric sensor 2051 installed at the center of the outer wall of the relay module 205, a release paper peeling plate 206 fixedly connected to one side of the top surface of the first riser 2, and a red and green flashing indicator light 101 fixedly connected to the center of the top surface of the desktop 1.

[0026] The photoelectric sensor 2051 is aligned with the release paper movement trajectory between the release paper tray 2021 and the transition roller 201 to monitor the ribbon status in real time. When the ribbon on the release paper tray 2021 is exhausted, the photoelectric sensor 2051 immediately transmits the signal to the information processing chip inside the relay module 205. After the information processing chip quickly analyzes the signal, it sends a stop command, cuts off the power supply to the device, and at the same time makes the red and green flashing indicator light 101 emit a red light to remind the operator that the ribbon inside the release paper tray 2021 has been exhausted.

[0027] like Figure 1 and Figure 3 As shown, the outer wall of the damping roller 202 is fitted with a release paper tray 2021.

[0028] After the release paper tray 2021 is fitted onto the outer wall of the rear damping roller 202, the tension of the release paper surface is kept stable by constant damping, preventing it from loosening during the conveying of the ribbon label.

[0029] like Figure 2-3 As shown, release paper is sleeved on the outer walls of multiple transition rollers 201, winding rollers 204 and release paper peeling plates 206. Photoelectric sensor 2051 detects the direction and the movement trajectory of the release paper.

[0030] The transition roller 201, the take-up roller 204, and the release paper peeling plate 206 jointly support the release paper conveying. When the release paper moves along the inclined surface of the release paper peeling plate 206 to the tip, the label is separated from the release paper by the acute tip of the release paper peeling plate 206. The photoelectric sensor 2051 detects the movement trajectory of the release paper and can directly capture the ribbon. When the ribbon is used up, the unobstructed signal is immediately transmitted to the relay module 205 to ensure the reliability of the ribbon monitoring.

[0031] like Figure 3As shown, a second stepper motor 301 is fixedly connected to one side of the bottom surface of the second heightening frame 3, and multiple rotating rollers 302 are rotatably connected inside the second heightening frame 3 via a rotating shaft. A rubber belt 303 is sleeved on the outer wall of the multiple rotating rollers 302, and one end of one of the rotating rollers 302 is fixedly connected to the output end of the second stepper motor 301. One side of the outer wall of the rubber belt 303 is close to the release paper peeling plate 206.

[0032] The second stepper motor 301 of the second riser 3 drives the rotating roller 302 and the rubber belt 303 to control the rotation speed of the product. In conjunction with the release paper peeling plate 206, the peeled label is tightly attached to the outside of the product.

[0033] like Figure 3 As shown, a label monitor 4011 is fixedly connected to one side of the top surface of the extension bracket 4, and the label monitor 4011 faces the outer wall of the release paper peeling plate 206.

[0034] When the label monitor 4011 detects a product with an unlabeled or incorrectly labeled product, the label monitor 4011 immediately sends an abnormal signal to the relay module 205. After the information processing chip analyzes the signal, it synchronously cuts off the conveyor power of the device, pausing the unlabeled or incorrectly labeled product at the labeling production line station.

[0035] like Figure 3-4 As shown, the telescopic end of the linear motor 401 is bolted to a U-shaped bracket 402, and both sides of the U-shaped bracket 402 are rotatably connected to multiple movable rollers 403 via rotating shafts. The U-shaped bracket 402 and the multiple movable rollers 403 are all located on one side of the rubber belt 303.

[0036] The linear motor 401 drives the U-shaped bracket 402 and the movable roller 403 to move outside the rubber belt 303. The movable roller 403 assists in supporting the product. The telescopic end of the linear motor 401 drives the movable roller 403 to rotate on one side of the rubber belt 303 through the U-shaped bracket 402 to assist in supporting the product, ensuring that the product does not shift when labeling.

[0037] like Figure 1-4 As shown, an information processing chip is installed in the center of the relay module 205, and the relay module 205, photoelectric sensor 2051, red and green flashing indicator light 101, first stepper motor 203, second stepper motor 301 and linear motor 401 are connected by wires.

[0038] The relay module 205 has a built-in information processing chip and is connected to the photoelectric sensor 2051 and the red and green flashing indicator light 101 via wires to ensure that the alarm is triggered and the machine stops in the shortest possible time after the ribbon is exhausted, thus ensuring timely interruption during the labeling process.

[0039] It should be noted that the tip of the release liner 206 is not sharp but has a rounded corner with a radius of 5mm. This creates a smooth transition when the release liner passes through, avoiding tearing or wear on the release liner edge caused by excessive sharpness, and ensuring the continuous stability of the ribbon during the conveying process.

[0040] The label monitor 4011 is an industrial camera. The industrial camera takes pictures of the product surface and uses image algorithms to compare it with the "standard label template". If the label outline is not identified (not affixed) or the outline offset exceeds the threshold (incorrectly affixed), it is judged as abnormal and an abnormal signal is output to the relay module 205, thereby cutting off the conveying power of the device and pausing the missing or incorrectly affixed products on the labeling production line.

[0041] Working Principle: On the labeling production line for round bottles, the conveyor belt is located between the U-shaped support 402 and the rubber belt 303. The end of the ribbon released from the release paper tray 2021 is guided by multiple transition rollers 201 and finally fixed to the outer wall of the take-up roller 204. At this time, the photoelectric sensor 2051 is aligned with the release paper path for real-time detection. When the ribbon is supplied normally, the photoelectric sensor 2051 continuously sends a sufficient ribbon signal to the relay module 205 and maintains continuous operation of the equipment. The red and green flashing indicator light 101 shows a solid green light. When the ribbon in the release paper tray 2021 is completely exhausted, the photoelectric sensor 2051, due to the loss of obstruction, sends a ribbon shortage signal to the relay module 205. The signal is analyzed by the information processing chip inside the relay module 205, which immediately cuts off the power supply to the device to achieve automatic shutdown, and simultaneously controls the red and green flashing indicator light 101 to switch to green. When the red indicator light 101 flashes red, the operator can quickly determine that the color tape behind is exhausted by observing the change in the status of the red and green flashing indicator light 101 above the equipment. This allows for timely replacement of the release paper tray 2021 to resume production. Simultaneously, the lens of the label monitor 4011 is vertically pointed towards the release paper path on the outer wall of the release paper peeling plate 206, capturing the labeling status of the products in real time. When information such as missing or incorrect labeling is detected in the captured image, the label monitor 4011 immediately sends an abnormal signal of missing or incorrect labeling to the relay module 205. After the information processing chip analyzes the signal, it cuts off the conveyor power of the labeling production line to stop the production. At the same time, it controls the red and green flashing indicator light 101 to switch to alternating red and green flashing, prompting the operator that there are missing or incorrect labels on the products on the labeling production line, requiring immediate inspection to prevent missing or incorrectly labeled products from being mixed into subsequent processing steps and causing more serious consequences.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
