Defined interfaces for air and waterunderneath the machine bed allowprecise planning of medium supply andquicker installation duringEasy control of the processThe upright was redesigned due to theincreasing amount of servo- and controltechnology. Furthermore, thedevelopment of the housing wasexecuted in such a way that allcomponents can be accommodated andthe clean design maintained.

The HMI ensures quickdoes not only cover the Heye servocomponents, but also a query andadjustment possibility for the operatingpressures, the optional dead plateMonitoring of the valves for functionssuch as final blow is a big step towardsmaintenance and job safety. Theoperator does not need to take a riskwhen accessing difficult areas to controlthe pressure functions, and the pressurecheck can be done without lossesHowever, it not only monitors whetherthe valve works, but also precisely how itAll valves are electrically controlled sothat the extensive cascade via the valveblock is omitted. For this, the structurecontains cable ducts that guide thecables upright. The adapter plates areprepared for the use of proportionalClean DesignHACCP is the abbreviation for thePoints concept, and is required by allmajor food fillers.

Thus, a clear andclean design resulted which is not onlyeasy to clean but also offers the operatora clear view through the entire machinefrom the blank to the blow side.

By arranging the injectorsabove the valve-block the air pipes areno longer crossed by the injector rackand its pipe work underneath the block. generation is now compactly arranged inthe operators field of vision.Additionally, a rapid interchangeabilityand an exactly pre-adjusted capacitythat matches the lubrication point sizeare ensured. Conveyor cooling, cable ways anddead plate cooling are also now installedin the conveyor body, ensuring thecables are optimally protected andguided the shortest possible way.heye speedline - web_00_GI_0909 5/6/14 10:00 AM Page 20Glass International May 2014www.glass-international.comFormingFor improved cleaning, and asprotection against dirt and heat, thepushers are surrounded by casings.Furthermore, they offer the option ofconveyor body via the cable channel. By directly positioning the pushersocket at the machine conveyor in frontof each section, the pusher can be easilyexchanged as it is possible to remove theplug to uplift the unit with the cable tail. The dead plate position for each cavitycan be monitored by an infrared sensorunderneath the dead plate over thewhole cycle run of a section. If the heatradiation is abnormal or does not exist ata certain time, a failure in glass handlingor demoulding has occurred. In thatcase, the following gobs for this sectionwill be rejected.

For this reason, whencarrying out the design of the new bedthe flow paths were kept short andstraight. In addition, the exhaust air forthe plunger cooling and valve block isguided directly into the atmosphere. Thus, the flow resistance could bethe plunger increased. By omitting theexhaust air, the back pressure into thevalve block could be eliminated as thereare no more interactions possible.
