Technical Field

[0001] This utility model belongs to the field of automated production line equipment, and in particular to a branch track merging system for a traditional Chinese medicine outer packaging production line. Background Technology

[0002] In existing Chinese medicine paper box packaging production lines, packaged medicine boxes need to be conveyed by two conveyor belts, and then merged into one conveyor belt at the parallel point for subsequent processes such as laser printing and electronic monitoring coding. The traditional paralleling method usually uses cylinder pushing, which is easily affected by air pressure and conveyor belt speed, causing the medicine boxes to be squeezed and deformed, resulting in cost waste, high failure rate, and affecting production line efficiency. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a branch track merging system for a Chinese medicine outer packaging production line, so as to solve the problems in the existing technology, reduce equipment failure rate, improve production efficiency, reduce labor costs, and reduce the risk of damage to medicine boxes.

[0013] Adjust the length of the side plate by adjusting the number of medicine boxes that can be gripped as needed.

[0014] Furthermore, it also includes a PLC, which is connected to the motor, cylinder, and two material detection photoelectric sensors.

[0015] Furthermore, it also includes a touch screen that connects to the PLC for sending control commands, allowing operators to set operating parameters via the touch screen.

[0016] Furthermore, it also includes a left limit switch and a right limit switch, which are installed at both ends of the slide rod.

[0017] Furthermore, the left and right limit switches are connected to the PLC to control the action of the servo motor, ensuring that the clamping box is clamped in the correct position.

[0021] Figure 1 This is a schematic diagram of the system structure.

[0022] In the diagram: 1 is the first conveyor belt, 2 is the third conveyor belt, 3 is the second conveyor belt, 4 is the servo motor, 5 is the slide bar, 6 is the slider, 7 is the cylinder, 8 is the gripping baffle, and 9 is the medicine box. Detailed Implementation

[0023] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0024] like Figure 1 The aforementioned branch track merging system for the Chinese medicine outer packaging production line includes: two independent conveyor belts, one merged conveyor belt, a linear motion mechanism, a cylinder that moves up and down, a gripping baffle, and two material detection photoelectric sensors.

[0025] Two independent conveyor belts, namely the first conveyor belt 1 and the second conveyor belt 3, are arranged in parallel and are used to transport the medicine boxes to be paralleled. These two conveyor belts are responsible for transporting the medicine boxes from the packaging station to the paralleling device, ensuring that the medicine boxes can enter the paralleling system smoothly and continuously.

[0026] A third conveyor belt 2 is formed by merging the first and second conveyor belts. The third conveyor belt is located between the first and second conveyor belts and is used to receive and transport the merged medicine boxes. The third conveyor belt is responsible for transporting the merged medicine boxes to subsequent processes such as laser printing and electronic supervision coding, so as to realize the continuous flow of medicine boxes.

[0027] The linear motion mechanism includes a servo motor 4, a slide bar 5, and a slider 6, which are used to control the movement of the clamping box. The slide bar is mounted above the three conveyor belts. The servo slider module is used to achieve high-precision motion control of the clamping box, ensuring the smoothness and accuracy of the pushing process.

[0028] The cylinder 7, which moves up and down, is mounted on the slider and is used to control the gripping and releasing action of the medicine box. The action of the cylinder is controlled by the PLC to ensure accurate gripping and releasing of the medicine box and reduce the risk of damage to the medicine box.

[0029] The gripping baffle 8 is used to grasp and release the medicine box 9. The gripping baffle consists of a top plate and two side plates, with the top two ends connected to the side plates. The top surface of the top plate is connected to a cylinder. The length of the side plates is adjusted to accommodate different sizes of cardboard boxes as needed, allowing for the control of the number of medicine boxes gripped. The design of the gripping baffle ensures the stability of the medicine box during gripping and release, reducing damage to the medicine box.

[0030] Two material detection photoelectric sensors are installed at the ends of two independent conveyor belts to detect the presence of medicine boxes. Using photoelectric or vision sensors, the position and quantity of the boxes are detected in real time to ensure the accuracy of the pushing operation. The material detection photoelectric sensors ensure that the system will only perform a gripping action when the medicine box reaches the predetermined position, improving operational safety and accuracy.

[0031] Left and right limit switches are installed at both ends of the slide bar, and a home switch is installed in the middle position to detect the initial position of the gripper box. These switches ensure that the gripper box is gripped and released in the correct position, improving the stability and reliability of the system.

[0032] This system is controlled by a PLC, which is connected to the motor, cylinder, two material detection photoelectric sensors, two limit switches, and a home switch. It achieves precise control over the movement of the clamping box, sensor signal processing, and cylinder actions. The PLC control system enables automated control of the entire paralleling process, improving production efficiency and ease of operation.

[0033] The PLC is connected to a touchscreen, which is used to send control commands. Operators set operating parameters (such as push quantity, delay time, speed, etc.) through the touchscreen. The touchscreen provides a user-friendly interface, allowing operators to easily adjust operating parameters to adapt to different production needs, thus improving the system's flexibility and adaptability.

[0034] The workflow of this system is as follows:

[0035] The medicine box is conveyed to the input end of the gripping baffle by the first and second conveyor belts. After the material detection photoelectric sensor detects the medicine box, it sends a signal to the PLC. The PLC controls the servo motor to move the gripping baffle above the medicine box based on the signal. Once the servo motor reaches the set position, the PLC controls the cylinder to actuate, and the gripping baffle picks up the medicine box. The gripping baffle places the medicine box onto the third conveyor belt. The third conveyor belt then transports the medicine box to the subsequent process. The operator sets the operating parameters and controls the entire operation of the device via a touchscreen.

[0036] Through the specific implementation methods described above, this system can efficiently merge the branch tracks of the traditional Chinese medicine outer packaging production line, improve production efficiency, reduce the risk of medicine box damage, and lower labor costs. Furthermore, the system has a high degree of automation, is easy to operate, and can adapt to the packaging needs of medicine boxes of different sizes and quantities, thus having broad application prospects.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model, and these all fall within the protection scope of the present utility model.
