DDS Hot Melt Adhesive Supply Unit
The DDS Series adhesive supply units (ASU) are computer-controlled hot-melt supply units designed on metric standards. Their “all-icon” control panels, with choice of display languages, are internationally operator friendly.
Available in two hopper sizes and with a choice of dual or single gear pumps, the DDS ASU uses a microprocessor temperature control to closely control the temperature of hot-melt adhesive for up to six hoses and six heads. The operator selects temperature set points for up to 15 zones, the system provides warnings and alarms for operator errors and system malfunctions.
Its DynaControl controller provides accurate, proportionate temperature control for the hopper, hoses and applicators. Sequential heating delays provide a program for turn-on of the hoses and heads. A “standby” temperature maintains the temperature zones at a lower temperature when the ASU is not in active use, enabling rapid return to normal operation. A seven-day scheduler allows advance programming of daily On/ Off times throughout the workweek.
With these flexible temperature program features, the DDS system increases adhesive life by eliminating prolonged high adhesive temperatures. It reduces energy consumption and brings the system up to normal operating temperatures in the shortest possible time.
A four-layered, shielded CPU board protects the microprocessor from external interference. The temperature control can interlock the parent machine with pre selected adhesive temperatures so that production automatically begins when adhesive temperatures are correct for the application. All system temperature values can easily and quickly be programmed.
The system provides digital readout of system conditions and optional external audible signals or lights to alert the operator to alarm conditions. A security code can restrict access to system programs and parameters. The CPU monitors the electronic circuitry and provides alarms for error conditions.
A choice of single or dual gear pumps, from 0.584 to 8.5 cc/rev, is available to assure a smooth and highly precise adhesive flow. The pumps may be driven by a single or dual drive.
The DDS’s teflon-coated hopper accepts adhesive in all popular forms, including pellets, slugs and blocks. The ASU can accommodate air-actuated automatic applicators (heads), electric applicators, hand-held applicators and/or special applicators. Options available include pressure gauge or transducer, drop-in grid, level control, Zenith gear pumps, digital RPM readout and casters.
