Also presented at the show will be a digital central lubrication unit with Bluetooth data transmission retro- fittable to all central granulators to - gether with a new edge trimming system for use in extrusion which is now servomotor-driven, so enabling optimum control. Hellweg has added a hardwaremod- ule to the Smart Control system that is capable of storing the power con- sumption of the machine it is fitted to over the long term, for example over a financial year, and providing it for analysis. Together with the ability to display power peaks, it provides valu- able data for optimizing energy use. The software itself now has the op- tion of controlling granulator speed in increments of one, so giving the user even more flexibility in tailoring ma - chine parameters exactly to require - ments. The SECURE+ package for the control system adds safety features. As soon as it detects imminent granu- lator overloads on the basis of motor current and torque values, it counter- acts them so that rotor blockages can virtually be avoided. Hellweg can nowoptionally equip all central granulators from the 260 series upwards which are used for grinding sprues, sheets, molded parts, sprue slugs and hollow items with a new cen- tral lubrication unit. Using a Bluetooth interface, the unit provides the opera- tor with all relevant data, such as bat- tery voltage, temperature, delivered lubricant volume as well as the time since the most recent pump stroke, operating time and number of pump strokes. The integrated, active report- ing system enables the operator to de- tect irregularities at an early stage and nip them in the bud. With an eye to sustainability, Hellweg also offers the option of refilling empty cartridges as part of its exchange service. The new R 200/20 Servo edge trim- ming system, a joint development with BREYER Extrusion, complements Hellweg's range of systems of this type, also known as guillotines or chippers. When trimming film webs, it pre-shreds one or two edge strips, which are then fed to a granulator for further processing. Its servo gear mo- tor means that cutting cycle times can be freely specified. The operator can use the touch display to select the cut- ting frequency for the trimming and so specify the length of the chopped edge strips at a constant cutting speed.
