With reference to Figure 1 , the yarn monitoring system comprises an input unit (200) embodied to permit entering of the information of the yarn provided in the feeding unit. In a possible embodiment of the present invention, said input unit (200) is a barcode reader used in reading the barcode of the yarn which is put to the feeding unit. With the help of said barcode reader, the identity information of the yarn is identified to the yarn quality monitoring system without needing manual entering. In a different possible embodiment of the present invention, the input unit (200) is a user interface arranged to permit manual data entering of the user. By means of said user interface, the yarn identity information can be identified to the system without needing barcode. Said user interface can comprise one of or a number of interface(s) which permit(s) entering of all data, like a touch-screen, keypad, etc. Moreover, in an exemplary embodiment of the present invention, in order to provide all of the described advantages, the user interface and the barcode reader are provided together.
The yarn monitoring system moreover has a control unit (100) comprising a processor unit (1 10) configured to receive the data entered to the user interface. Said control unit (100) comprises a memory unit (120) embodied to record data in a temporary and permanent manner. The control unit (100) moreover comprises a communication unit (130) embodied to realize wired and wireless communication with peripheral units.
An exemplary operation scenario of the present invention is described below;
An identity information of the yarn, provided in the yarn feeding unit which is ready to be used in the weaving loom, is entered to the input unit (200). Said IP identity information comprises at least one of the information of the yarn like the information of the supplier of the yarn, total unit amount of the yarn, thickness of the yarn, denier of the yarn, raw material of the yarn, yarn resistance, break-elongation number, break-extension number, tolerance values.
The yarn identity information taken from the input unit (200) are taken by the processor unit (1 10) and recorded in the memory unit (120). The output signals coming from the yarn break sensor (300) and indicating that the yarn is broken as from the time where the yarn is begun to be used in the weaving loom are received from the processor unit (1 10) and counted and recorded in the part of the memory unit (120) associated with the yarn identity information.
The processor unit (1 10) is embodied to access the reference breakage values associated with the yarn identity information. In a possible embodiment of the present invention, the reference break values comprise the permitted standard break values, determined according to the identity information of the yarn, and the permitted tolerance values. In an exemplary embodiment of the present invention, the reference break values may be provided beforehand in the memory unit (120) or said values may be taken by means of the communication unit (130) through a server.
The processor unit (1 10) compares the yarn break number recorded in the memory unit (120) and the reference break points, and when there is a predetermined deviation from the reference break number, the processor unit (1 10) generates an output signal indicating that the yarn quality is not suitable. In a possible embodiment of the present invention, the processor unit (1 10) is embodied to notify the predetermined persons and/or the supplier company by means of a communication unit (130) that the yarn quality is not suitable when the processor unit (1 10) determines that the yarn quality is not suitable.
