System Description
 

Standard system consist of a three degree of freedom cartesian robot, polyurethane machine, low pressure dynamic mixing head, fixed table and temperature conditioning unit.

 

HS10 was designed especially for high speed and precise three dimensional dispensing of sealants, glues or encapsulants.

 

Common base frame for controls and polyurethane machine, and welded steel body construction of the robot, makes HS10 as robust as possible.

 

System mechanics consist of maintenance-free ball circulating linear guides for extended life time, rack-and-pinion drives for high speed and high acceleration/deceleration rates, maintenance free servo motors and precision gearboxes.

 

The system control is based on powerful industrial CNC unit with linear, circular, and helical interpolation ability. The CNC unit is programmed in G code according to DIN 66025 and special software for enclosure cabinets is also supplied. The modular architecture of the CNC control unit allows easy integration in existing production lines. The system has Industrial operator panel with 12“ colour touch display and membrane keypad as an operator friendly interface for programming, running and controlling the machine. All the operating parameters, such as output, dispensing values, speed and acceleration/deceleration ramps can be monitored and controlled through extensively visualized menus.

MH2C07 low pressure dynamics mixing head

 

 Mixing head

 

MH2C07 is a compact, low pressure dynamic mixing system for precise meter, mix and dispensing for liquid to high viscous polymeric reactive materials. Flexibility of the mixing head makes it suitable for dispensing of complex parts and applications. Modular design and the consequent separation of valve group and mixing chamber make the MH2C07 maintenance friendly. The mixing head is equipped with two pneumatic actuated needle seat valves for materials, one flushing and one blowing valve. The mixer and the mixing chamber are made of stainless steel. Tungsten Carbide axial face seal isolates the mixing chamber and the mixer shaft. All mixing chambers have cooling and heating systems for stabilizing the temperature.

 

Mixing head output capacity ranges, regulated by the respective configuration of pumps from 0.3 to 100 g/s with a dosing accuracy of +/– 1%, thus covering a wide field of applications. The stirrer speed can be electronically adjusted between 0-9000 rpm to optimize the production process. Specific stirrer design, environmentally friendly recirculating cleaning system and the maintenance free anti-drip nozzle shut-off device makes up for perfect construction.

  

Environmentally friendly cleaning system

 

Biodegradable cleaning agent is used for mixing head cleaning system which separated out from the waste, recycled after the flushing and used several times. It is a real proven alternative to cleaning systems with methylene chloride in terms of performance, economy and greatly improved environmental health and safety.
