Description

Technical Field

[0001] This utility model belongs to the technical field of material handling machines, specifically a control system for a material handling machine. Background Technology

[0002] In the fireworks and firecrackers production industry, the material sorting machine is the core equipment of the automated production line for fireworks tubes. Its main function is to precisely arrange, sort, or organize disordered stacked fireworks tubes (usually small-diameter, long strips of paper tubes) according to process requirements, providing an orderly material flow for subsequent processes. The quality of the material sorting of fireworks tubes directly affects the safety and production efficiency of subsequent processes—if the arrangement is not neat, it may lead to uneven charge during loading, insecure sealing, or even explosion accidents; if the material sorting efficiency is low, it will restrict the capacity of the entire production line. Traditional material sorting machines, due to problems such as poor vibration parameter adaptability, insufficient multi-channel coordination, low sorting accuracy, lack of status monitoring, and unstable power supply, can no longer meet the material sorting requirements of fireworks tube production. Therefore, it is urgent to design a material sorting machine control system specifically for the characteristics of fireworks tubes, which can solve the above-mentioned technical problems through intelligent parameter adjustment, real-time collaborative control, and feedback. Utility Model Content

[0003] To address the above problems, this utility model provides a control system for a material handling machine, which solves the technical problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A control system for a material handling machine includes a controller, and a feeding control module, a vibration material handling drive module, a multi-channel material conveying monitoring module, a material handling sorting adjustment module, and a feedback adjustment module electrically connected to the controller. The feeding control module is used to control the speed and opening / closing state of the baffle belt conveyor to achieve smooth material conveying from the hopper to the vibrating material handling device. The vibration feeding drive module is used to transmit vibration power to the drive component, control the vibration frequency and intensity of the swing frame, and realize the feeding of materials. The multi-channel material conveying monitoring module is used to distribute the sorted material to different channels and gather it to the next level through a fixed inclined channel, while adjusting the conveying speed of each upper guide section to achieve effective distribution and gathering of materials in different channels. The material sorting and adjustment module is used to adjust the running speed of the belt segment and the action of the telescopic device, control the back-and-forth shaking of the partition, and sort and align the materials. The status monitoring module is used to monitor the status of each fixed component and the connection point with the frame, and feeds the feedback to the controller to ensure the stability of the device. The feedback adjustment module is used to acquire material conveying and sorting image information at the observation window and feed it back to the controller to dynamically adjust the working status of each component.

[0005] As a further improvement to the above solution, the feeding control module includes a motor driver electrically connected to the baffle belt conveyor drive motor, which is used to receive controller commands and adjust the speed of the drive motor, thereby controlling the conveying speed of the baffle belt conveyor.

[0006] As a further improvement to the above solution, the vibration material handling drive module includes a vibration driver electrically connected to the rotating shaft of the drive component; the vibration driver receives pulse signals or current adjustment commands from the controller to control the magnitude and frequency of the vibration power transmitted by the drive component to the rotating shaft, thereby adjusting the vibration intensity of the swing frame.

[0007] As a further improvement to the above solution, the multi-channel material conveying monitoring module includes: Flow monitoring unit: An ultrasonic flow sensor or weighing sensor (electrically connected to the controller) installed on the side wall of the collecting tank is used to monitor the total flow rate of materials passing through the collecting tank. As a further improvement to the above solution, the material sorting and adjustment module includes: a motor speed controller electrically connected to the belt segment drive motor, used to receive controller commands and adjust the speed of the drive motor to control the running speed of the belt segment; An electromagnetic reversing valve electrically connected to the telescopic device (such as a cylinder) is used to receive controller commands and control the frequency and stroke of the cylinder's telescopic movement, thereby driving the second partition to vibrate back and forth.

[0008] As a further improvement to the above solution, the feedback adjustment module includes: A camera positioned at the observation window is used to collect real-time image information of material conveying and handling. An image processor electrically connected to the camera is used to analyze image information (such as identifying material arrangement density and offset) and generate a status feedback signal. The image processor transmits feedback signals to the controller, which then adjusts the operating parameters (such as belt speed and guide section angle) of the feeding control module, vibration material handling drive module, multi-channel material conveying monitoring module, or material handling sorting adjustment module based on the signals.

[0009] As a further improvement to the above solution, the controller is a programmable logic controller (PLC) or a microcontroller unit (MCU). As a further improvement to the above solution, a power supply module is also included to provide a stable DC or AC operating voltage for the controller and other modules.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application constructs a fully automated material handling control system by integrating a controller with modules for coordinated feeding control, vibration-driven material handling, multi-channel material conveying monitoring, material handling sorting adjustment, status monitoring, and feedback adjustment. This solves the problems of traditional material handling machines relying on manual intervention, low adjustment accuracy, and poor stability. The controller acts as the central hub to uniformly schedule all modules, significantly improving material handling efficiency and product consistency while reducing labor costs.

[0011] The feeding control module controls the conveying speed of the baffle belt conveyor through an electrical connection between the motor driver and the drive motor. Speed ​​commands sent by the controller allow for real-time adjustment of the drive motor speed, preventing hopper blockage due to excessive feeding speed or idle running of the vibrating feeder due to excessively slow feeding speed.

[0012] The vibration feeding drive module achieves dynamic adjustment of the vibration frequency and intensity of the sway frame through the electrical connection between the vibration driver and the drive component shaft. Vibration parameters can be adjusted in real time according to material characteristics, significantly improving the flexibility and adaptability of the feeding process.

[0013] The multi-channel material conveying monitoring module monitors the material flow rate in the collection tank through ultrasonic flow sensors or weighing sensors, enabling real-time sensing of the multi-channel material conveying status.

[0014] The material handling and sorting adjustment module controls the belt speed and partition vibration through a motor speed controller and an electromagnetic reversing valve, respectively, to achieve precise coordination of material conveying and sorting.

[0015] The feedback adjustment module uses a camera and image processor to provide visual feedback and dynamic adjustment of the material status, thus constructing a closed-loop system of "monitoring-analysis-control". The power module provides a stable voltage to the controller and other modules, which is the fundamental guarantee for the reliable operation of the system. A stable power supply reduces heat loss and aging rate of electronic components, extends the service life of the controller and sensors, and reduces equipment maintenance costs, providing strong support for the long-term stable operation of the material handling machine.

It is responsible for receiving feedback signals from each module (such as flow rate, image, vibration parameters) and sending control commands (such as motor speed, vibration frequency) to each execution module to realize the full-process automated control of the material handling machine.

[0022] (2) Feed control module 200 The feeding control module 200 is used to control the speed of the baffle belt conveyor 1 to achieve smooth conveying of the firework tubes from the hopper to the vibrating material handling device 2.

[0023] Composition: Includes a motor driver that is electrically connected to the drive motor of the baffle belt conveyor 1.

[0024] Working logic: The controller 100 sends a speed command to the motor driver based on the upstream material feed speed (such as the feedback from the hopper weighing sensor), which drives the motor to adjust the conveying speed of the baffle belt conveyor 1, ensuring that the material enters the vibrating material handling device 2 at a uniform speed, and avoiding blockage caused by feeding too fast or idling caused by feeding too slow.

Image processor: Based on the YOLOv8 target detection algorithm, it identifies the arrangement of the gun barrels and generates a status feedback signal; (7) Power module 700 The power supply module 700 is used to provide a stable DC or AC operating voltage (such as 24V DC or 220V AC) for the controller 100 and each module.

[0038] Composition: Includes an AC-DC switching power supply (input 220VAC, output 24VDC / 10A), a filter (to suppress mains harmonics), and a voltage regulator circuit (output voltage fluctuation ≤ ±5%).

[0039] Functions: Stable power supply ensures reliable operation of controller 100, sensors (such as ultrasonic flow sensors), and actuators (such as motor drivers), extends the life of electronic components (extends the life of controller 100 from 3 years to 5 years), and reduces maintenance costs (annual maintenance costs are reduced by 25%).

[0040] 3. Workflow Example Taking the material handling process of a 15cm long paper firework tube as an example, the workflow of the control circuit is as follows: Feeding stage: The cannon barrel in the hopper is conveyed to the vibrating material handling device 2 by the baffle belt conveyor 1.

[0042] Multi-channel material conveying stage: After being straightened, the barrel enters the collection tank through the upper guide section 301, and the ultrasonic flow sensor monitors the flow rate of each channel.

[0043] Material sorting stage: The barrel enters the belt section 401, the motor speed controller adjusts the belt speed (0.6m / s) to match the output speed of the vibratory material sorting; the electromagnetic reversing valve controls the cylinder 403 to vibrate (frequency 2Hz, stroke 100mm), driving the partition 402 to align the barrel.

[0044] Feedback and adjustment phase: The camera captures images, the image processor detects a slight blockage in a cannon barrel, the controller 100 increases the vibration frequency of the baffle 402, and the adjustment is completed within 3 seconds, and the blockage is cleared.
