DEPRAG SCHULZ GmbH from Amberg, Germany, is one of the global market leaders in the field of automated screw driving and feeding technology.
Their recipe for long-term success is the continued drive for evolution and innovation, combined with the development of intelligent and efficient system solutions. With this in mind, DEPRAG Schulz GmbH developed their complete CleanFeed concept with specific CleanFeed components to meet the requirements for technical cleanliness in feeding.
It includes elements for low abrasion part feeding to minimise the generation of damaging particles from the outset. Low abrasion sword feeders are particularly gentle at sorting, separating and suppling fasteners.
Sensors on the device automatically determine the number of strokes necessary so that stroke movement and therefore abrasion is kept to a minimum. Furthermore, hoppers help to keep a consistently low quantity of fasteners in the feeding system because fewer screws mean less contamination.
However, because the generation of particles cannot be entirely eliminated, suction systems are also an effective method of creating cleanroom conditions. The DEPRAG “Particle Killer” targets and removes dirt particles before assembly and ejects them through a filter.
The DEPRAG SFM-V vacuum screw driving module on the other hand, uses suction to remove residual dirt directly from the screw driving tool via additional vacuum sources.
As well as modifications to the hardware, particle contamination is also combatted by intelligent adjustments managed by the controller, such as a reduction in speed during bit engagement with the screw head, at the same time averting wear and tear on the tool.
