EXcProXP microprocessor control Long processing units IC ® Intracool apc ® air power cooling Cincinnati Extrusion argos 3 ARGOS The argos concept Novel gearing Solution The argos extruders are the first machines worldwide with a four-shaft drive mechanism, a solution offering decisive advantages over the conventional three-shaft gearing mechanisms with a simple 1:1 split of the dri- ving torque. In the four-shaft solution, the torque for the second screw is split again in a 1:1 ratio to drive two auxiliary shafts at levels above and below the se- 4-shaft gearbox cond screw shank. This way, the individual pair of ge- ars driving the screw has to take merely 25 % of the overall torque. The extreme loadability connected with this type of gear train enables to work with the kind of torques required to achieve high output rates at low screw speed. argos transmission systems are equipped with highly efficient plate heat exchangers. The close control of oil 5 28 x D temperature provides maximum lubrication security. 28D processing Unit The long processing unit with an effective screw length from the feeding port’s front edge of 28D is a core feature of the new argos range of twin-screw extruders. Optimal temperature-mediated control of the process and a unique processing latitude are the 7 4 6 3 2 1 benefits for the user.

The processing unit with an effective L/D ratio of 28:1 keeps stress on the raw material at a minimum by efficient heat transfer guaranteed by an optimal residence time spectrum and large internal surfaces. argos extruders are designed for utmost mechanical reliability. An innovative four-shaft concept is used for the distributor drive and enables to work with high torque at low screw speed. Overheating is safely avoided so that top product quality is consistently ensured. Additional safety is built in by the driver’s large centre distances.

With the high L/D ratio, more than tripling of the residence time in the pre-heating zones is achieved - greatly improving the processing performance.

The motors are mounted alongside the distribu- tion gearbox to save space. The argos 72-28D has the main motor flange moun- ted directly to the reduction gearbox. All other extruder drives are mounted on the extruder frame. The degassing system and the optional external screw temperature control system are positioned directly be- low the barrel. argos DC-drive units Configuration argos extruders use modular design concepts. De- pending on the application, the machines feature an L/D ration of 23:1, 26:1 or 28:1 and purpose-tailored motor power corresponding with the particular reduc- tion gear ratio and screw speed maximum. The control cabinet with the rotating operating termi- nal is mounted on the left side of the extruders. The standard screw centre height is 1100 mm. Special versions with non-standard extrusion height or stand- alone control cabinet are offered upon request. argos AC-drive units Optimal plasticizing units - processing length and tempera- ture control save energy Vented unit Cincinnati Extrusion argos 7 ARGOS Extruder versions Parallel twin screw extruder argos 114 8 Cincinnati Extrusion argos APPLICATION TECHNOLOGY Pipe (R), profile (P) and sheet (PL) versions of the argos extruders are available.

Screw configurations were developed which ensure optimal processing characteristics for the particular application. Profile Extrusion Fully flighted variable pitch screws are used which process impact modified PVC with minimal stress and yield perfectly homogenous extrudates. Pipe Extrusion The large number of flights in the pre-heating zone of Fully flighted twin-screw the pipe screws creates the kind of large internal sur- face area which ensures that the required energy can be input without excessive compression and stress on the material. Sheet Extrusion Configuration and make of the sheet screws ensure perfect homogenisation of the melt, a crucial capabili- ty in sheet production. Over 1.000 kg of the top quali- ty sheet without any flow lines can be reached per Pre-plasticising zone with a high number of flights hour by the argos 132.

Vertical dosing Unit (synchronized) Especially designed for non free flowing or highly fil- led U-PVC-formulations. The vertical dosing unit con- sists of a hopper with a vertical dosing screw. It is mounted over the barrel feed port, and may be pivo- ted away from the barrel for emptying, access, etc. Metering unit Vertical dosing unit 12 Cincinnati Extrusion argos TECHNOLOGY Depending on the properties of the material and other requirements, the customer can choose between a variety of feeding variants. Direct gate-controlled feeding from the full hopper or a metering unit can be used. Additionally special vertical dosing units and crammer feeders for poor flowing formulations are available. Crammer Feeder (synchronized) This is used to feed poor flowing P-PVC formulations. Paddle-type agitators prevent material bridging inside the hopper. Gravimetric feeding (synchronized) For continuous throughput measuring, and resulting control to minimize fluctuations in output and/or me- tre weight. Can be used in conjunction with a dosing feeder. The additives can be incorporated by additional Crammer feeder dosing units.

The proven HELIOS automation modules from Cincinnati Extrusion are also available for the new EXc PRO-XP control with improved performance and en- hanced user-friendliness. Temperature Control Dramatic improvements have been made to tempera- ture control since the last version. Shorter settling ti- mes could be achieved without loss in stability and the accuracy of temperature control could be pushed up to its physical bounds. With the new EXc PRO-XP systems, supreme quality of temperature control does not have any special skills and abilities of the machine operator as a precondition. All temperature controllers of the system are based on the most ad- vanced control algorithms and are self-optimising. 14 Cincinnati Extrusion argos CONTROL A suitable control system makes it possible to operate an extruder even more economically. A new control generation has been developed that embodies current trends and developments in the field of personal computers (PCs) and programmable logic control (PLC).

The modem nee- ded and the Internet account are shipped as standard with every CET-extruder featuring EXcPRO-XP con- trol. Tele-servicing permits not only data copying and display - it also provides genuine remote operation, including control/process diagnosis. Consequently, program modifications, such as activation or adapta- tion, can be made easily. Tele-servicing via the Internet with the possibility of simultaneous access by several engineers offers unique advantages. For example, a process engineer may carry out a process diagnosis through the remote control functions provided while a software specialist, who may even be located in a different place, uses programming tools to diagnose and perhaps modify the visualisation/PLC software directly.
