Micro Piezo Inline Feeder ZEP090

NEW!!  The next generation of screwfeeding technology using Piezo crystals instead of the old coil based technology. The new Micro Linear range accommodates small and micro sized fasteners and gently pre-sorts the fastener orientation prior to allowing them to load into a buffer, ready for escapement and delivery. The Piezo unit is extremely quiet and compact in footprint making it an excellent choice for workplaces with high value real estate around the process areas. The noise levels are extremely low and the unit has a vibration which is much less aggressive than 60Hz or 120Hz coil devices which means significantly less abrasion and damage to fasteners and their finish.

What makes these different:

This new concept in micro-screwfeeding has only two moving assemblies and they are both controlled by applying a voltage across a set of Piezo crystals which oscillate in reaction to this voltage. The crystals and angular flat springs perform the conversion into a linear motion. This vibration does away with the old electromagnetic coils which required tuning and tighter controls to get that sweet spot which allowed vibration to be transferred into the parts being fed. There was also the issue of heat generation and electromagnetic field generation which sometime could be problematic. This product is now driven by two Piezo crystals which results in a non-magnetic, light weight, high performance and extremely controllable feed mechanism. Frequencies can range from 140 to 400hz range and lends itself to smaller light mass fasteners and parts. This technology offers very high feed rates and it has become much easier to offer aligned screws, pins, studs and other small parts to be delivered in the correct orientation for the customers demands.
