System description
The intelligent paper roll conveying system is mainly responsible for the transportation and management of the raw paper required on the corrugated production line. It is divided into the paper roll conveying part, the paper roll feeding part, and the paper roll transport part and paper roll discharge part. It consists of mechanical hardware and control software, which truly realizes intelligence, efficiency, it is very helpful to improve the overall speed of the whole corrugated line, and also reduces labor costs and intensity.
The system is an advanced one. The buyer only needs to be responsible for the pre-embedded parts, pipelines, air supply, communication cables and power cables. The supplier is responsible for designing the complete transportation system and providing the equipment system and control system, software systems, pneumatic systems, hydraulic systems, foundation pit cover production and guidance installation and training.
paper roll in-feeding platform
1.the paper storage platform can store 2 to 3 paper rolls according to the size, and automatically distribute each base paper to the original paperboard chain conveyor through the paper separator;
2.improve the efficiency of holding the car and reduce the fuel consumption of the car; no need for the workers to push the paper, reducing the labor intensity of the workers;
3.into the original paper platform away from the workers' work area, greatly improve the safety of the workshop;
paper centering equipment
1.It is not only used as a conveying channel, but also used for base paper turning, which is convenient for conveying process needs
2.Realize the unmanned automatic operation of the system
board chain turntable
1.each section of the original cardboard chain conveyor can store 1 or 2 pcs of paper roll under static conditions. According to the signal from Corrugated line tract, the original paper is automatically kicked over, which is very helpful for improving the speed of the vehicle;
2. reduce the loss of the paper roll and reduce the running cost
3.realize the unmanned automatic operation.
In-feeding board chain conveyor
1.each section of the original cardboard chain conveyor can store 1 or 2 pcs of paper roll under static conditions. According to the signal from Corrugated line tract, the original paper is automatically kicked over, which is very helpful for improving the speed of the vehicle;
2. reduce the loss of the paper roll and reduce the running cost;
3. realize the unmanned automatic operation.
paper roll discharge terminal
After weighing, the rest paper of the paper roll passes through the out-feeding conveyor line, and automatically stops at the center of the out-feeding. According to the original paper information, the paper roll is pushed out of the out-feeding conveying line through the kicking arm, and enters the discharging paper platform. Be easy to hold the paper quickly
automatic labeling machine
1.after the production line, the residual paper roll passes through the weighing system, and the actual weight is displayed on the meter. Erp reads the weight data of through rs232 communication and prints the label by itself, or the data is fed back to the paper roll conveying management software. The labeling machine is connected, and the label of all the information of the paper roll is automatically printed and attached to the original paper;
2.
it is convenient for ERP to analyze and calculate the loss of the paper roll to control the production cost;
3.Managing the stock of raw paper in time
4.
Before returning the paper roll to the weighing board chain, the out-feeding control system is connected with the paper roll conveying management software. The software reads the information and weight of the original paper, then send to the automatic labeling system, and the label is attached to the round surface of the original paper, which realizes the unmanned and convenient data management. This labeling system can also prints the current weight of the paper roll and attaches the label to the paper roll, even if no conveying management software.
automatic control system
1.Adopts Siemens 1500 series PLC, which uses independent processing communication data and logic program to support high-speed counting, pulse transmission, DP bus, ethernet communication and other functions;
2. the main equipment of the system include: plc control cabinet, inverter cabinet, field control box, emergency stop button box, photoelectric switch, proximity switch, various control switches and signal lights and buzzer alarms.
3.
this system adopts automatic control, with automatic/manual switching function and closed loop self-correction function.
4.the system has self-diagnosis and operation fault alarm function; the CPU module of the plc will automatically diagnose the operation of the plc module. When the equipment in the conveyor system fails during operation, the system will give an audible and visual alarm signal to remind the user, and the cause of the fault will be automatically displayed on the alarm screen of the touch screen, which is convenient for self-control maintenance personnel to overhaul. The emergency stop device, after the emergency stop on the site is pressed, disconnects the corresponding main circuit to ensure safe production.
5.the system has a remote supervision function, which requires the customer to provide the external network to the control cabinet;
layout of main equipment
the direction of the original paper stick drive.
brief description of process: (the process is based on the final design)
1.In-feeding paper roll process:
The paper roll to be conveyed is placed on the automatic paper feeding platform according to the arrangement list, and the paper roll is smoothly fixed on the board chain conveyor through the automatic paper feeding platform and the pneumatic paper holder. After the original paper is conveyed through each of the turntable and transported to each conveyor lines, and automatically sent to appointed place of the Single facer according to signal. The operator controls and remove the paper roll from the chain line.
2.Out-feeding paper roll process
After the raw paper of the production line is taken off the shelf, it is sent to the six-plate chain conveyor line, and then the horizontal paper is transferred to the paper-back conveying line through the original paper turntable. When the original paper roll reaches the end-plate chain conveyor, the weighing system works and weighs. After the paper roll information is transferred to the original paper conveying management system, the new label is attached to the round surface of the paper roll. After the completion, the original paper is kicked out and stored in the storage area, which is convenient for holding.
