First, the vertical packaging machine overview
The vertical packaging machine is a machine in which a roll-shaped flexible packaging material is made into a bag cylinder, and after filling the material, sealing is performed, and 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.
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.
Second, the characteristics of vertical packaging machine
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.
Third, the vertical packaging machine works
The film of the roll placed on the supporting device is wound around the guide bar set and the tensioning device, and the position of the trademark pattern on the packaging material is detected by the photoelectric detecting control device, and then rolled into a film cylinder through the former to wrap the filling tube surface. 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 tube bag.
Fourth, PLC: OMRON multifunction machine CP1H (analog type)
Advantages:
Built-in USB programming port, and can be configured with RS232, RS485 communication serial port, so that PLC can connect man-machine interface, thermostat or inverter at the same time. It can use FB (function block) function to communicate with OMRON's thermostat or inverter, saving the tedious 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 horizontal seal, etc., no additional positioning module is needed, saving cost for customers
CP1H's powerful interrupt function can be used to write the program of the color code fixed length in the input interrupt program without the influence of the cycle scan time and right, increasing the real-time performance of the servo start and stop.
HMI: OMRON color touch screen NS series
Advantages:
Rich variety of screens
Extremely compatible with OMRON controllers
Rich SaP library function, communication with some devices of OMRON factory (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, up to 16 languages ​​in one screen
Supports up to 1000 recipe functions
Servo: OMRON Smartstep Z Series Servo
Advantages:
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)
Advantages:
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 PLC or man-machine interface can directly call the function block without user programming
External SSR models can directly open larger capacities
Sensor: E3X-DaC Fiber Sensor
Advantages:
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 impact of the misoperation judgment caused by the interval change.
With white LED, it is not necessary to replace the light source for all kinds of inspection workpieces, so it can be detected more easily, safely and correctly.
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 were saved, but also the overall performance of the machine was greatly improved.
Precision Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.
Convex Aspheric elements are used to reduce aberrations, apheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
VIS coating option provides less than 1.5% reflection from 425 – 675nm. NIR coating option provides less than 1.5% reflection from 600 – 1050nm. Contact us for volume pricing of the custom aspheric lenses.
