PROCESS IDENTIFICATION SYSTEM FOR SPINNING MACHINES

FIELD OF THE INVENTION

The present invention relates in general to textile machines. Particularly the present invention relates to a method and apparatus to avoid process/product mix-up through an improved process identification system for spinning preparatory machines. Still particularly, the present invention relates to an apparatus and method for process identification and an loT enabled wireless network communication system to monitor the process through online especially for spinning preparatory machines.

BACKGROUND OF THE INVENTION

The spinning preparatory machines such as carding, lap formers, combing machines, draw frames and speed frames are involved in a process to remove the short fibres and impurities present in the raw cotton, parallelise and converting the fibres in the form of thin strand of fibres so called sliver or roving. Normally, in a spinning mill, different types of materials are processed in different machines at the same time.

In the existing art, "Colour coding system" is the most commonly used method for identifying the different materials. For example, from raw material to finished product, same colour of containers are used to identify a particular process. For this method, a greater number of containers in different colours are required in each department. Alternatively, colour bands and labels are used as identification means in the plain containers especially cans with white in colour in spinning preparatory machines. The conventional colour coding system requires manual operations, extreme care, high investment and more storage space. Also, the existing methods are not suitable for the operators with colour blindness. Although the drawbacks are recognised by various machine

manufacturers, no fool proof system for process identification has so far been introduced which would satisfy all the requirements by the mills.

A patent application WO2018051362A1 filed by the applicant discloses a process and product identification system for spinning preparatory machines. Said process identification apparatus comprising a decoding and encoding arrangement, a driving arrangement, said decoding/encoding device comprises a control unit, plurality of sensing means, decoding/encoding device with a driving means and said control units are connected with wireless communication network system. Said process identification apparatus, is mounted in the delivery zone of the spinning preparatory machines. The containers with transponders are decoded and encoded with process data and said containers are monitored by electronic receivers mounted in the creel zone of the spinning machines. The data from all control units and electronic receivers are sent to Internet of things (loT) enabled wireless communication system.

The above system uses pneumatic or hydraulic operated pistons to move the encoding device. The constructions of encoding and decoding apparatus have not clearly explained. The working method and said encoding and decoding devices are not disclosed.

Another Indian 201941011630 filed by the applicant as a patent of Addition for the above patent application discloses an apparatus and method for process identification system for spinning machines. Said patent application discloses an encoder apparatus which is mounted on the delivery portion of the machine and said encoder uses the driving arrangement of the machines to rotate the Cans. The encoder is identified when the containers are rotated using the machine driving arrangement. Also, this system is connected with the machine’s control unit to collect and communicate the desired data. Though the system is

successful, the permission from machinery manufacturer to implement the changes in their machines.
