,TagSPECI:FIELD OF THE INVENTION

The present invention relates to a silk reeling machine. More particularly, the present invention is directed to provide a pedal operated silk reeling machine which is a leg driven machine which helps in winding the silk thread passing through set of guiders by rotating the bobbin with the help of connecting rod, crank wheel and pinion gears. The longitudinal turning of silk thread is done with the help of cam traverse assembly. The crank wheel is mounted on a shaft which helps in rotating the bobbin with the help of pinion gears and also powers the cam traverse assembly to ensure narrow and long thread distribution along the bobbin reel. All the six spindles of the machine can be reeled at once with the same amount of force hence increasing the productivity of the workers by substantially reducing the menial work involved and providing good working conditions, thus would significantly benefit the artisans or workers who are involved in silk reeling process as livelihood in rural areas.

BACKGROUND OF THE INVENTION

Silk reeling is used for reeling together cocoon produced from silk worm into a single thread. At first, the Cocoon is treated with hot water to soften the sericin which helps in turning the single strand onto a fast moving bobbin resulted from unwinding the filaments at once from 4-8 cocoons. In the existing method of silk reeling, all the process involving rotation of bobbin, feeding of cocoon etc are done manually.

Presently, traditional silk reeling is done by using the charkha (spinning wheel) which is operated manually by a single person rotating the reeling wheel with one hand and feeding the cocoon with the other. This process is not smooth and consistent with lots of jerk resulting in substantial amount of idle time due to breakage of thread, requiring huge amount of time and exhausting physical labor which leads to low productivity.

In order to achieve successful silk reeling, operation needs to be smooth and consistent without jerking. This is generally not possible to achieve in traditional method which results in substantial amount of idle time due to breakage of thread, requiring huge amount of time and exhausting physical labor resulting in low productivity.

Two Indian patents could be traced which is related to silk reeling device but do not improve the efficiency and productivity of traditional silk reeling methodology to desired level with minimum manual effort.

Indian Patent No. 162271(498/MAS/1984) by DR. M S JOLLY disclosed a silk reeling charkha for reeling silk which used traditional charkha for reeling purpose.

Indian Patent No. 196267(572/MAS/1997) by CSTRI, Bangalore disclosed a silk reeling and twisting machine. This invention relates to a silk reeling cum twisting machine wherein the machine has a basin secured with the base frame near the top side at one end thereof. A jetteboute mounted above the basin is provided for easy casting to the yarn. Twisting means are provided at the top of the frame towards the basin side. Spindles are mounted on the top of the frame of the machine opposite to the twisting means. A fly wheel adapted to be driven by drive means is mounted rotatably at the bottom of the frame below said spindles. Driving means are provided at the bottom frame opposite to the fly wheel for rotating the fly wheel. A swift is mounted on the top of the frame at the basin end for converting the silk into the hankform.

It is observed that none of the prior art devices have the features and novelties that the proposed simple pedal crank operated silk reeling machine of the present invention has.

There has been therefore a persistent need in the related field to develop a silk reeling machine which would enable successful silk reeling operation in a smooth and consistent manner free of jerking avoiding substantial amount of idle time due to breakage of thread as found in traditional silk reeling using conventional charkha/spinning wheel, and thus eliminating consumption of huge amount of time and exhausting physical labor while ensuring superior quality of product.

It can be found in accompanying Figure 1 that the pedal operated silk reeling machine according the present invention comprises an articulated Frame(R) which is constructed by angled iron material on which all the above components are fixed and supported. There is a Pedal(A) mounted at the bottom portion of the Frame(R) and is angularly designed to reduce the leg movement to operate the machine. A Connecting Rod(B) is operatively connected to said pedal(A) that helps in converting the reciprocating motion of pedal to the rotational motion of a crank wheel(C) which is mounted on a shaft(E) and drives the shaft. The shaft(E) is used to transfer the power to connected components like cam, pinions, etc. A set of Pinion-gears(D) are connected with the shaft and used to rotate the bobbin and powers a cam traverse assembly. When the operator pedals the machine, the angular reciprocating motion of the pedal(A) is converted to the rotational motion of crank wheel(C) with the help of off-centered connecting rod(B).

A First Guider(G) mounted just above the cocoon feeding tray(F) comprising a set of first guiding rings through which the silk thread is passed. A Second Guider Wheel(H) comprises a set of guiding wheels on top through which the silk thread is next passed. A Wooden Cylindrical Log(I) is mounted below the second guiding wheel(H) and provides as a rough base from which the silk thread is passed ensuring minimal breakage. A Third Guider(J) comprises a set of third guiding rings through which the silk thread is passed and fed to the rotating bobbins(M) through traveler (K). Silk thread is passed through the Traveller(K) which rotates around the bobbin to wrap it completely at one plane wherein Travelling rings(L) act as a path for traveler. Bobbins(M) are mounted below the traveller and each bobbin is a reel onto which the silk thread is winded. Each Bobbin is mounted on bobbin pin(N) which rotates freely. Traverse Assembly(P) ensures narrow and long thread distribution along the bobbin reel. A Cam(Q) mounted on the shaft, powers the traverse assembly(P) to cause reciprocating motion of the traveler(K) along the length of the bobbin(M). A Flywheel(O) is mounted on the driven shaft to provide constant momentum to reduce the jerking action ensuring minimal breakage of the thread.

It is thus possible by way of the present invention to provide a pedal operated silk reeling machine which is a leg driven machine that helps in winding the silk thread passing through set of guiders by rotating the bobbin with the help of connecting rod, crank wheel and pinion gears. The longitudinal turning of silk thread is done with the help of a specially configured cam traverse assembly.
