At present, the vertical packaging machine on the market can basically run at 120bpm (bags/min), and the speed can reach 60-80bpm with the on-line metering and filling machine.
Process Description:
The vertical packaging machine is characterized in that the feeding cylinder of the packaged material is arranged inside the bag maker, and the bag making and filling materials are carried out in the vertical direction from top to bottom. The vertical packaging machine is mainly composed of a measuring device, a transmission system, a horizontal sealing and vertical sealing device, a molding device, a filling tube and a film pulling and feeding mechanism.
The working principle is as follows: the film of the roll placed on the supporting device, the group of the guiding rods and the tensioning device are passed through, and the position of the trademark pattern on the packaging material is detected by the photoelectric detecting and controlling device, and then rolled into a film cylinder through the shaper. Wrap on the surface of the filling tube. First, the film of the interface portion rolled into a cylinder is longitudinally heat-sealed by a longitudinal heat sealer to obtain a sealed tube, and then the tubular film is moved to a transverse heat sealer for transverse sealing to form a package bag. The metering device fills the metered item into the package through the upper filling tube, and then heat seals by the transverse heat sealer and cuts it in the center to form the package unit body, and at the same time forms the bottom seal of the next package.
PLC: OMRON multifunction machine CP1H (analog type)
Advantage:
Built-in USB programming port, and can be configured with RS232, RS485 communication serial port, so that PLC can connect man-machine interface, temperature controller or inverter at the same time. It can use FB (function block) function to communicate with OMRON's thermostat or inverter, eliminating the need to write cumbersome 485 communication program.
Built-in four-way 100kHz high-speed pulse output, control four-way servo system, realize precise positioning and speed control of pulling film traction. When it is necessary to expand servo function such as cross-sealing, no additional positioning module is needed, saving cost for customers.
CP1H's powerful interrupt function can be used to write the program with fixed color length in the input interrupt program, without the influence of the length of the cyclic scan, increasing the real-time performance of the servo start and stop.
HMI: OMRON color touch screen NS series
Advantage:
Rich variety of screens
Extremely compatible with OMRON controllers
Rich SAP library function, communication with some devices of OMRON (such as thermostat) only from the SAP library
Paste the part on the screen, no need to make a picture or ladder
Support for languages ​​in 41 countries, one screen can display 16 languages
Supports up to 1000 recipe functions
Servo: OMRON Smartstep Z Series Servo
Advantage:
It is equipped with a further automatic gain adjustment function. The parameter setting is simple. The content to be set is almost the same as that of the stepping motor. Compared with the stepping motor, it has a higher torque vortex flowmeter.
All adjustments are done automatically by the servo drive
Temperature control scheme: E5â–¡Z series thermostat + G3NA series solid state relay (SSR)
Advantage:
The E5â–¡Z series thermostats are automatically adjustable and self-adjusting. Automatic adjustment even when self-adjustment is being performed
RS485 serial communication with OMRON's PLC or HMI can directly call the function block without user programming
External SSR models can directly open larger capacities
Sensor: E3X-DAC fiber optic sensor
Advantage:
Equipped with a color sensing engine, the color information of the workpiece itself is processed by RGB three primary colors to achieve the purpose of detecting the workpiece.
Enhance the ability to detect the deviation of the workpiece in the field against the workpiece detection, and reduce the influence of the misoperation judgment caused by the distance change.
The white LED is used to detect various workpieces without replacing the light source, making it easier, safer and more accurate.
OMRON's complete product system covers almost all the industrial control products required for vertical packaging machinery, and each product has its own independent advantages and has very high compatibility between our products. Customers use OMRON complete system to solve After the solution, not only the workload and development cost are saved, but also the overall performance of the machine is greatly improved.
The overall solution for vertical packaging machines
The vertical packaging machine is a machine that makes a roll of flexible packaging material into a bag, fills the material, and seals it, and the three functions are automatically and continuously completed. In conjunction with the above-mentioned metering and filling machinery, vertical packaging machines are often used for packaging blocks, sheets, granules, stems, powders, and fluid and semi-fluid materials.
