Document Type and Number:
Japanese Patent JP2731814
Kind Code:
B2
Abstract:
The invention relates to a monitoring system for knitting machines, in particular for such machines as are intended for the knitting of hosiery or socks, comprising a number of yarn guards allocated to each yarn intended for infeed into the machine, the guards each being operative, in response to a movement or absence of movement of the yarn, respectively, detected thereby, to generate and output signal to stop the machine in the event of, for example, yarn or thread breakage or other fault in the yarn infeed, by the intermediary of preferably electronic control unit connected to the yarn guards. The invention is primarily characterised in that the control unit includes memory and comparison means and is, in such instance, arranged to gather and memories, during an introductory, correct and approved working or report cycle of the machine, information representing the yarn infeed phase in the form of the actual pattern of output signals from the yarn guards. The control unit is further arranged thereafter to compare, during subsequent working or report cycles of the machine, the pattern of output signals thus registered and memorised during the introductory, correct and approved working or report cycle with the actual pattern of output signals registered during the current, subsequent working or report cycle in order, in the event of a discrepancy therebetween, to generate a fault signal for stopping the machine.
