The speed problem is also the design difficulty of the horizontal filling and sealing machine. Especially the design of the single-axis process packaging machine will affect the output. In this traditional design, all the main components - product conveyor, wing seal, etc. ——It is driven by the spindle under the action of high horsepower motor and mechanical cam. However, mechanical gears and large motors can cause sudden stop and start up difficulties. Other challenges facing control systems are:
â—† Quickly complete the film changing process;
â—† Adjust the action configuration in the stop state to adjust the position of the product or film;
â—† Keep the precise positioning of the film when the machine speed is increased;
â—† Maintain consistent film tension and accurately cut and seal the film;
â—† Ensure accurate inspection and removal of waste products;
â—† Generate machine designs that can be easily changed according to consumer and product requirements.
Rockwell Automation's solution integration architecture allows engineers to assemble machines that are fast and efficient to operate because of:
The Ultra300 drive independently controls and powers each major component, breaking the limits of single-axis equipment for OEMs and users.
The motion commands provide phase adjustment for the interrelationship of various transmission mechanisms and cam systems.
The high speed positioning cycle (less than 50 microseconds) provides advanced control of the machine disc cutter.
High-resolution feedback devices (up to 2M/rev) support provide high bandwidth servo response.
The registration flag of the Logix system allows you to enter the position of any physical axis and also select the time of occurrence. This time can be used to determine the exact location of any other physical and imaginary axes in the system, helping to control precise film positioning.
The Logix control system—combined with product tracking technology (shift registers) and output cams – accurately triggers the waste handling mechanism without burdening the controller.
Horizontal filling and sealing machine design difficulties
It is very important to design the accuracy of the horizontal filling and sealing machine: the conveyor speed and the sealing shear function must be synchronized so that the two products are of the same grade, and small calculation errors and time errors may lead to unnecessary waste. In addition, conveyor belts that are separated by a certain gap must be coordinated to ensure that the product is positioned in the proper position; at the same time, the film must be centered so that the product name and logo are in a visible position.
