Operation monitoring system

Claim 1

A system for monitoring the operation of a multispindle textile winding frame having one or more banks of spindles to determine the efficiency of the operation and the number of yarn breaks, comprising: a plurality of one-shot multivibrator circuits associated one each with respective ones of said spindles in said bank or banks of spindles for providing a series of scan pulses of predetermined length and repetition rate; a plurality of switches located one each at said spindles and in circuit with respective ones of said one-shot multivibrator circuits, each of said switches operable to normally be in a first condition when no break in the yarn associated therewith exists and to be in a second condition when a break in the yarn associated therewith does exist; a plurality of bistable multivibrator circuits in circuit with respective ones of said switches, each of said bistable multivibrators normally being in a first conductive condition when no yarn breaks exist and respective ones of said bistable multivibrators being in a second conductive condition when breaks exist in the yarns associated with said respective ones of said bistable multivibrators; a first counter driver circuit coupled to said plurality of switches; a first counter in circuit with said first counter driver circuit for counting the number of scan pulses passed by the switches when the switches are in said first condition; a second counter driver circuit coupled to said bistable multivibrator circuits; and a second counter in circuit with said second counter drive circuit for counting the number of times said bistable multivibrator circuits change from said first conductive condition to said second conductive condition.

Claim 2

A system for monitoring the operation of a multispindle textile winding frame having one or more banks of spindles to determine the efficiency of the operation and the number of yarn breaks, comprising: a plurality of one-shot multivibrator circuits associated one each with respective ones of said spindles in said bank or banks of spindles for providing a series of scan pulses of predetermined length and repetition rate; a plurality of switches located one each at said spindles and in circuit with respective ones of said one-shot multivibrator circuits, each of said switches operable to normally be in a first condition when no break in the yarn associated therewith exists and to be in a second condition when a break in the yarn associated therewith does exist; a plurality of bistable multivibrator circuits in circuit with respective ones of said switches, each of said bistable multivibrators normally being in a first conductive condition when no yarn breaks exist and respective ones of said bistable multivibrators being in a second conductive condition when breaks exist in the yarns associated with said respective ones of said bistable multivibrators; a first counter driver circuit coupled to said plurality of switches; a first counter in circuit with said first counter driver circuit for counting the number of scan pulses passed by the switches when the switches are in said first condition; a second counter driver circuit coupled to said bistable multivibrator circuits; and a second counter in circuit with said second counter drive circuit for counting the number of times said bistable multivibrator circuits change from said first conductive condition to said second conductive condition.

Claim 7

A system for monitoring the operation of a multi-spindle textile winding frame having one or more banks of spindles to determine the number of yarn breaks comprising: means for generating a series of electrical pulses of predetermined length and repetition rate, switch means associated with each spindle, having a first position when the associated spindle has a yarn break and having a second position when the associated spindle does not have a yarn break, means connected to said generating means and to each of said switch means so that each of said pulses is successively coupled to a different one of said switch means, and means connected to each said switch means for producing a given electrical signal when that switch means is in said first condition and a pulse is coupled to that switch means so that manual operation of said switch means when a pulse is not coupled will not produce said given signal.

Claim 8

A system for monitoring the operation of a multi-spindle textile winding frame having one or more banks of spindles to determine the number of yarn breaks comprising: means for generating a series of electrical pulses of predetermined length and repetition rate, switch means associated with each spindle, having a first position when the associated spindle has a yarn break and having a second position when the associated spindle does not have a yarn break, means connected to said generating means and to each of said switch means so that each of said pulses is successively coupled to a different one of said switch means, and means connected to each said switch means for producing a given electrical signal when that switch means is in said first condition and a pulse is coupled to that switch means so that manual operation of said switch means when a pulse is not coupled will not produce said given signal.

Claim 9

A system for monitoring the operation of a multi-spindle textile winding frame having one or more banks of spindles to determine the number of yarn breaks comprising: a plurality of switch means, each associated with a different spindle, each having a first position when the associated spindle has a yarn break and each having a second position when the associated spindle does not have a yarn break, interrogation means for applying a given electrical signal to each of said switch means, means connected to each said switch means for producing an electrical signal indicating a yarn break when that switch means is in said first position and said given electrical signal is being applied to that switch means so that manual operation of said switch when said given signal is not being applied to that switch means will not cause said indicating signal to be produced.

Claim 10

A system for monitoring the operation of a multi-spindle textile winding frame having one or more banks of spindles to determine the number of yarn breaks comprising: a plurality of switch means, each associated with a different spindle, each having a first position when the associated spindle has a yarn break and each having a second position when the associated spindle does not have a yarn break, interrogation means for applying a given electrical signal to each of said switch means, means connected to each said switch means for producing an electrical signal indicating a yarn break when that switch means is in said first position and said given electrical signal is being applied to that switch means so that manual operation of said switch when said given signal is not being applied to that switch means will not cause said indicating signal to be produced.
