  • Detail

The innovation of packaging machinery comes from the control system

a rich and advanced automatic product system is used by Hensen packaging technology and equipment company to manufacture the most modern beverage packaging machinery

Hensen packaging technology and Equipment Co., Ltd. (HPC), located in Bremen, Germany, has 25 years of experience in the field of manufacturing advanced packaging machinery. The advanced and easy-to-operate control system built by Rockwell Automation integration system makes the packaging machinery design obtain continuous innovation ability

packaging machinery calls for automatic control

hpc company is famous in the world for its filling and sealing machinery. Its products include a series of standard machinery and special machinery, which can meet different market needs and applications. HPC company is a professional manufacturer providing filling and sealing machinery for vertical cartons and soft bags. The corresponding field of its products is transitioning from refillable packaging bags to constantly updated fast-moving consumer goods. HPC also carries out carton processing and mechanical assembly, and has the manufacturing capacity of the whole packaging system production line. The use function of Hensen machinery can be flexibly adjusted, and this type of equipment is easy to maintain, and it can still maintain stable performance when running at high speed, and can quickly change the type and model of products

hpc's customers are mostly manufacturers that produce and package fast-moving consumer goods such as beverages. They face fierce market competition, so they need to constantly develop new products to attract consumers' attention. In Germany, vertical cartons and soft bags are used as the main refillable packaging, but in North America and the Far East, resealable vertical soft bags are currently the main packaging forms of liquids such as energy, sports drinks, laundry fluids and personal care fluids. This kind of vertical soft bag used for the outer packaging of sports drinks is very eye-catching on the shelf because of its soft curve and hand-held pattern. People who are thirsty after sports can drink drinks more conveniently and smoothly. Today's high-speed and fully automated packaging machinery needs to have the most modern hardware and software control systems. Such control systems include precise motion control system, convenient human-machine interface and powerful logic control system

choose an integrated supplier

as a supplier with customers all over the world, according to the Mongolian Minister of culture, tourism and sports, Olympic Geller, HPC needs a well functioning automation equipment manufacturer to provide it with first-class, global technical support and parts supply. HPC also hopes to cooperate with experts who have made achievements in the field of high-end automation to speed up the upgrading of plastic granulator technology, and develop an advanced control system for a new generation of packaging machinery with the help of professional knowledge and rich experience

after carefully investigating some automation equipment suppliers, HPC finally chose Rockwell Automation as its supplier, and took Allen Bradley Logix automatic control platform as the standard accessory of its latest packaging machinery. Logix is a brand of programmable logic controller (PLC) series, including a series of brands from powerful ControlLogix to compact FlexLogix. Because Logix series provides a variety of specific models of controller PLC to choose from, HPC can always choose the appropriate controller to be applied to different occasions, from small machinery to large production systems. Because all Allen Bradley PLCs use the same Logix control core, they all use the same easy-to-use rslogix5000 software language to program. HPC engineers only need to be familiar with this development tool to be competent. A set of codes can be common among PLCs of different models in this series

convenience and flexibility are even more powerful

controllogix integrates logic and motion control into one control system, and can use the same set of development tools for these two controls, namely rslogix5000 language, to program conveniently. In addition to this general development environment, Logix series PLC also uses NetLinx's unique Allen Bradley network protocol with open software interface to ensure the effective flow of data. Using NetLinx protocol, as using DeviceNet, ControlNet, ethernet/ip and other protocols, data can be transmitted easily; And because these networks use the open CIP internet protocol, they can be directly connected to the manufacturer's ERP (Enterprise Resource Management) and other business IT systems

because of the fully open transmission protocol, NetLinx ensures that the machine can be set from any input port of the machine. Engineers can program the equipment through the network without direct physical connection with the controller, which greatly shortens the time of equipment debugging and commissioning

similarly, the maintenance engineer can diagnose, debug and modify the program in the control room without going to the machine. Through the use of Internet technology, this concept has been further developed. When installing an Allen Bradley 9300, users should remember to turn off the controller and computer rades modem, so that they can dial from anywhere in the world to connect the entire control network based on NetLinx protocol

NetLinx protocol is the key of Rockwell automatic control integration system. It ensures that the hardware and software in this system can be perfectly combined when leaving the factory, cooperate with each other and work together. The integrated system provides many benefits to machine manufacturers such as HPC. For example, it greatly shortens the time of designing and building control systems, and improves the operating performance of the whole machine, making the machine easier to maintain and more reliable, while improving the production efficiency and profitability of manufacturers

another benefit of using Allen Bradley platform DeviceNet is that fully automated device replacement (ADR) can be achieved. The ADR function enables the replacement of devices such as Allen Bradley PowerFlex drives without shutting down the network. In the event of a system crash, the downtime can be minimized

controllogix uses SERCOS digital interface and high-speed optical fiber network to realize data transmission between controller and servo driver. Optical fiber network replaces large bundles of wires, and it can also send and receive driver status information. The benefits of using SERCOS also include more convenient machine debugging, higher accuracy of operation, and more stable system operation performance

hpc also adopts Allen Bradley GUARDMASTER machine safety system of Rockwell Automation Company as standard accessories. This safety system provides a complete set of safety products, from simple interlocking devices to shielding systems using laser scanners and light curtains. The GUARDMASTER system meets all the safety requirements of HPC and ensures the compatibility with Allen Bradley control system

the advantages of Rockwell Automation's integrated system are embodied in HPC's latest packaging machine ho auto. This packaging machine adopts an integrated motion and logic control system to realize the following functions: insert a nozzle into a carton and seal the seams

machines using ControlLogix controllers can quickly and easily handle cartons of different sizes or specifications. When the size of the nozzle inserted into the carton needs to be changed, the key components of the machine need to be changed; When relocating the key components of the machine, compared with the traditional machine, the control component PLC of the new machine adopts DeviceNet protocol to send instructions to the servo driver, which greatly shortens the time required to complete this process

the operator can select the required machine settings through the Allen Bradley PanelView man-machine interface, and then complete the remaining work through ControlLogix. Allen Bradley flex i/o modules are distributed in different parts of the machine. Through this module, the control of the water pressure valve can be realized, and the signal of the sensor can be fed back; It uses DeviceNet to realize data exchange with PLC. In the past, a considerable number of wires were used to transmit signals to the console, but now the number of wires is greatly reduced. After this process is completed, the carton can be transferred to the next production link through the conveyor belt or track

hpc also applied the motion control system of Rockwell Automation Company to its CMF filling and sealing machine equipment. This continuous operation machine can handle up to 250 cartons per minute. These cartons can be provided by the track system or directly by the ho auto carton forming machine. The carton is sent to the CMF by an index system that will push up the price of domestic wood pulp and pass the patent, and is guided to the loader

here the carton is guided onto a rotating conveyor belt with 12 filling and sealing stations. This process can also achieve enhanced sealing

the filling position on each CMF rotating conveyor belt is equipped with an Allen Bradley MP series low inertia servo motor, which is controlled by an Allen Bradley ultra3000 digital servo driver. Because MP series motors have a high torque/size ratio, they only occupy a very small space on the transmission belt and are easy to install. The ultra3000 drive is also installed on the conveyor belt and connected to the ControlLogix PLC through the SERCOS interface. The conveyor belt is connected to other parts of the machine through the slip ring, so that the DeviceNet and SERCOS networks can operate seamlessly through the rotating node

the cartons filled and sealed are sent to the last packaging process through the conveyor belt controlled by PowerFlex adjustable speed drive

"the perfect integration between network and servo technology realized by Logix greatly shortens the engineering time" Jorg von mallotkie, a programmer of HPC, said: "this is because a program can be used to set the machine from a single point of the machine. In the debugging and commissioning stages, fault diagnosis can also be carried out through a single point interface, which greatly shortens the installation and debugging time of the machine."
