VERVANGINGSMONDSTUK VOOR EEN VACUUEM SCHROEFAS EN INRICHTING VOOR HET UITVOEREN VAN DE VERVANGING.

摘要

An adapter is attached to the end of a vacuum spindle in order to facilitate automated fastening and unfastening therewith of various vacuum nozzles. During fastening of a nozzle, vacuum is utilized to pull and hold the adapter and nozzle together with a force which is much greater than the mechanical detenting which is conventional in this art. The various nozzles may have component engaging tips of different sizes and configuration such that each nozzle is selectable as appropriate to the size and contour of the component to be held by vacuum drawn through the spindle. A novel reservoir housing a multiplicity of replaceable vacuum nozzles is also disclosed whereby the nozzles may be exchanged without any external separation or attachment force supplied by the downward or upward movement of the spindle.
