Device for controlling the operation of machines, particularly textile machines, able to self-learn the operating cycle of these latter and to correct its own errors during this self-learning stage

Claim 1

A device for controlling the operation of machines, particularly textile machines, of a type able to self-learn an operating cycle of these latter and comprising means for monitoring movement of yarns used for forming fabric, means for sensing commencement of a machine production cycle, means for measuring an operational velocity of a machine, means for memorizing data or information regarding yarn movements required to produce a master fabric, comparator means for comparing yarn movements during fabric production with the master yarn movements, means for detecting any error between the yarn movements relating to the master fabric and subsequent movements, and means for halting the machine when such an error is determined, said device being characterised in that the memory means are connected to comparison means arranged to compare the master data with the instantaneous data relative to fabric under production, said data or information being generated by sensor means located in positions corresponding with said yarns, said comparison means being connected to control means arranged to act on the machine, to interrupt its operation, following an error signal emitted by the comparison means, said control means establishing which sensor means has emitted a real data item dissimilar to the corresponding master data item and how many times said sensor means has generated said data item, said control means then modifying said master data item fed into the memory means if the error or the real data dissimilarity is repeated constantly with time.

Claim 2

A device for controlling the operation of machines, particularly textile machines, of a type able to self-learn an operating cycle of these latter and comprising means for monitoring movement of yarns used for forming fabric, means for sensing commencement of a machine production cycle, means for measuring an operational velocity of a machine, means for memorizing data or information regarding yarn movements required to produce a master fabric, comparator means for comparing yarn movements during fabric production with the master yarn movements, means for detecting any error between the yarn movements relating to the master fabric and subsequent movements, and means for halting the machine when such an error is determined, said device being characterised in that the memory means are connected to comparison means arranged to compare the master data with the instantaneous data relative to fabric under production, said data or information being generated by sensor means located in positions corresponding with said yarns, said comparison means being connected to control means arranged to act on the machine, to interrupt its operation, following an error signal emitted by the comparison means, said control means establishing which sensor means has emitted a real data item dissimilar to the corresponding master data item and how many times said sensor means has generated said data item, said control means then modifying said master data item fed into the memory means if the error or the real data dissimilarity is repeated constantly with time.
