System M5 is a state of the art automatic spreader system for one, two or three component adhesives. The machine will automatically apply the adhesive over a programmed surface area meanwhile the workers prepare the next layer or inserts the insulation into the panel as the machine moves down the panel length. M5 is specifically designed for an efficient manufacturing of large sandwich panels and with a wide variety of options and design flexibility the system will be customized to match your production.
The M5 machine services a multiple of press/lay-up tables placed on either side of the machine track. The track can extend up to 100m to service a large set of tables. From the machine an arm extends out to the side above the press table. On the arm a trolley carries the adhesive spreader and moves it perpendicular to the track. The adhesive is applied through the spreader across the width of the panel.
The surface area can be programmed and stored as a recipe. The machine system will be designed and programmed to match your material flow, plant layout, products, selection of adhesive and environment.
The adhesive components are pumped through pipes and hoses laid down in an energy chain at the side of the machine track with the pump station positioned at the side of the production line. The pumps are of air driven piston type and the mixing ratio metering is done by mechanically linked measuring cylinders. The spreader is of steel and can be made at any width up to 600 mm.
When the work is complete the spreader is cleaned in a flush and cleaning station. For an one component adhesive system the spreader is automatically immersed and protected in an oil tray protecting the spreader from contact with the surrounding moisture in the air.
The operator programs the surface dimensions into the machines control system and then jogs the machine into starting position by guiding a laser marker. To simplify the operation the commands are performed using a hand held remote control. When in position the operator presses the start button and the machine applies the adhesive automatically on the surface area in accordance with the chosen programming and the operator can attend to preparing the next layer (or place the core material as the machine moves along the track). After the first adhesive layer is complete the process is mirrored by turning the direction switch.
When the work is complete the operator removes the spreader and mixer tube from the machine and clean them in the flush station. After reassembling the mixer and spreader onto the machine the system is ready for use again.
