Cards pile comb drive system in machines for the textile industry.

摘要

trigger mechanism for combs staccavelo in machinery for the textile industry of the type comprising a structure of combs (27) mounted so as to oscillate around a position of rest, i knowall the point of elastic media (23 and 24) accumulators of mechanical energy, and associated with means for electric motor (20) of the type which on rotation can be reversed with the variation of degnale electric.the motor means (20) are associated with a detector (31) of the instantaneous angular position of the shaft (30) of the engine (20) and, consequently, the instantaneous angular position of the structureto comb (23, 26 and 27).the detector (31) is connected to a feeding unit (21) of the engine (20) in order to establish a system of persistent fluctuations on the variable component of the engine (22) and, as a resulton the structure of combs. the motor means (20) may be represented by an engine of the type "brush - less" or from an engine in continuous current with constant field excitation.among the advantages of the invention are those that use a structure of electric motor is proportionate to the work that must be done by the combs staccavelo and permbe a more precise adjustment of the operational parameters of the combs staccavelo to adapt the motion to the various work situations.
