Field Of Invention
The present invention relates to the field of textile industry and in particular to the manual processes of jacquard card punching involved in the textile industry.Background of the Invention
Textile has been one of India's major sources of income since yore. The Textile Industry has been one of the oldest and most important sectors of the Indian Economy. The potential of Textile Industry is tremendous as India is the third largest producer of cotton in the world. India stands at the first place in terms of area under cultivation; as such India has the potential to become the largest producer of cotton. Our labor is easier and cheaper. Over and above there is a culture of textiles in India. India's inherited textile culture and craftsmanship are only the reasons for Indian textiles to survive the global competition but not the technology. If there is technological up gradation with adequate policy implementation, it can be said without hesitation that India can be on the top of the global list.
The dispensing equipments in use in the textile industry have inherent drawbacks of large size, heavy weight and immobility, thereby affecting the operation efficiency, as well as accuracy of measurements. This harnesses significant progress and exploitation of the Indian textile industry potential. In this world of rapid technological development, it is necessary for executives and operatives in the textile industry to be familiar with the modern methods and employ automated systems, which have now become indispensable to achieve significant progress. Due to increased demand and the need to cater the requirements of a much wider clientele drawn from all sections of society, textile products have been more diverse and the quality has declined as the product has increased.The present day methodology for textile pattern designing development is completely manual. The textile industry presently uses Jacquard cards that are a type of perforated cards. The perforated cards were passed over needles pressed against the card. Whenever a hole came up the needle would go through the hole activating the threading mechanism. The pattern of holes on the cards determined the pattern that would be produced on the resulting textile.
The manual method demands high cost in terms of time and money. A system is needed to make the textile processes of Jacquard card development simple, faster, better as well as to get rid of cumbersome old methods.Objects and Summary of the Invention.It is an object of the present invention to overcome the aforementioned drawbacks and provide an automated system for jacquard card punching.It is another object of the present invention to develop an automated system that works in unison with the existing handloom/ powerloom machines.It is yet another object of present invention to develop Jacquards automatically for both 200 and 400 capacity machines.It is further an object of present invention to automatically punch wooden cards.
To achieve the aforementioned objectives the invention provides a system that automates the manual textile process of Jacquard card development.

COMPLETE SPECIFICATION

Field of Invention
The present invention relates to a method and system for electronic replacement of wooden jacquard cards. It generally relates to the field of textile.
Background of Invention
The textile industry has been using Jacquard looms since 19th century. It was developed by Joseph-Marie Jacquard and could produce complex patterns as easily as earlier machines had produced plain cloth. The weaving of cloth on the Jacquard loom was controlled by punch cards that enabled the loom to weave any pattern automatically. In his loom a series of connected perforated cards were passed over needles pressed against the card. Whenever a hole came up the needle would go through the hole activating the threading mechanism. The pattern of holes on the cards determined the pattern that would be produced on the resulting textile.
The introduction of Jacquard cards was a revolution in the field of textile. Any complex design could be easily weaved. This affected the speed and efficiency but still there was a limitation. A jacquard is either of the type 25 X 8 or 50 X 8, so at a time only a maximum of 400 threads can be controlled. This limits the speed of the weaving process. Moreover the mechanical system used to mount the jacquards is very bulky and occupies a large amount of space.
The prior art in this field comprises many patents. US5275211 relates to electromagnetically activated jacquard control arrangement. It comprises a plurality of control elements each combined with a lifter element (16) and each provided with an electromagnet (19) with an armature (21). The mechanics used here is very different and this does not solve the problem addressed in the instant invention.
There has been no invention that can actually replace the wooden jacquard cards in an efficient manner.
The dispensing equipments in use in the textile industry have inherent drawbacks of large size, heavy weight and immobility, thereby affecting the operation efficiency, as well as accuracy of measurements. This harnesses significant progress and exploitation of the Indian textile industry potential.
Objects and Summary of the Invention
It is an object of the present invention to overcome the aforementioned drawbacks and provide a system for replacing jacquard cards.
It is another object of present invention to control more threads at a time.
It is further an object of present invention to improve the speed of the weaving process.
It is yet another object of present invention to develop Jacquards automatically for both 200 and 400 capacity machines.
It is yet another object of present invention to replace the bulky mechanical systems mounting wooden jacquards.It is still another object of present invention to avoid the need of large number of jacquards.
To achieve the aforementioned objectives the invention provides a system that overcomes the need of wooden jacquard cards. According to present invention, the system creates a soft jacquard file out of the weave pattern. The soft jacquard file controls the movement of electromagnets in the system that act as jacquards.
The present invention relates to,
A system for electronic replacement of wooden jacquard card comprising:
software means for creating a weave pattern,

computer means for generating a soft Jacquard file from said weave pattern, an electronic circuit controlled by said soft jacquard file,
said electronic circuit having electromagnets and an array of relays to control said electromagnets for developing said weave pattern.
This invention further relates to a method for electronic replacement of wooden jacquard cards comprising the steps:
creating a weave pattern on a computing system,
generating a soft jacquard file from said weave pattern,
controlling an electronic circuit having electromagnets and an array of relays, by
said jacquard file and,
developing said weave pattern by said electromagnets.Brief Description of Accompanying DrawingsFigure 1 shows the flow diagram for replacing wooden jacquard cards.
Figure 2 shows the electronic circuit for the instant invention.Detailed description of Drawings
The present invention provides a system where the punched cards are replaced by electromagnets. The system contains means to develop a processed image tile (10>. means to develop a jacquard file from said weave pattern (11), an electronic circuit (12) containing electromagnets that replace jacquard cards and an array of relays to control the electromagnets. Figure 1 illustrates a flow diagram for the working of the present system. A weave pattern (10) can be either a pattern developed with the aid of a package or can be obtained by scanning an image. Scanning serves as the easiest way to bring a paper based design to computer that can be fed to the present invention. The image is fed to a PC (11). The computer creates a soft jacquard file on basis of the weave pattern. The output of the PC (1 i) is connected to an electronic circuit 12. The electronic circuit
contains an array of relay and electromagnets. The position of relays (ON/OFF) determines whether the electromagnets are to be ON/OFF. According to presenl invention, a hole is simulated with an ON position. Any number of threads can be controlled at any time. Also since the electromagnets take less space, at a time many electromagnets can be mounted, thereby reducing the time of weaving.
The above method is implemented through a circuit an example of which is described below. A man skilled in the art would appreciate that another circuit with the same objective can be designed.
Figure 2 shows an electronic circuit, which is connected to electromagnets. The electromagnets here are a substitute for the bulky jacquard cards. The soft jacquard file is input to the circuit at the input means (20). An amplifier (21) operates according to the instructions in the soft jacquard file. The output from the amplifier operates a relay device (23). A relay would be in an ON or OFF state depending on the output of the amplifier. The relay in turn is connected to electromagnet. The electromagnets turn ON or OFF depending on the state of the relay devices. In a design pattern, the electromagnets would be ON where a hole would have been punched in the Jacquard caret and the electromagnets would be OFF where a hole is not needed in the jacquard card The ON/OFF of an electromagnet controls the motion of a spring loaded pin. The pin is spring loaded to maxe it come back to the original position once the electromagnet is switched off. The resistor (22) controls the voltage of the circuit. The circuit of the relay device is not shown, as it is known to a person skilled in the art.
The above mentioned relay devices are arranged in an array, just like jacquard cards are conventionally arranged. Each relay device in the array is controlled by a circuit.
It will readily be appreciated by those skilled in the art that the present invention is not limited to the specific embodiments shown herein. Thus variations may be made within the scope and spirit of the accompanying claims without sacrificing the principal advantages of the invention.
