FIELD OF THE INVENTION

The present invention relates to ring spinning and twisting machine, more particularly to a cleaning arrangement of the peg trays arranged as a closed loop and carries a plurality of pegs provided for the transport of empty conical tubes from the tube loading zone to the spinning positions and the cops from the spinning positions to the unloading zone of the ring spinning and twisting machine.

According to the invention, the peg itself act as a cleaning element for the removal of dust, fly, lint and other small waste matters accumulated over the peg tray during every doffing cycle.

BACKGROUND OF THE INVENTION

Most of the modern ring spinning machines are provided with auto doffers for the exchange of cops with empty conical tubes at the end of the cop built up cycle. Pegs are arranged in peg tray and are being displaceable in a closed loop in between the tube loading zone and the cop unloading zone. It Is necessary to provide equal number empty conical tubes arranged on pegs underneath the spindle rails before the end of the cop built up. The pegs carrying the cops are transported to the unloading zone of the ring spinning machine where the cops are unloaded and the empty pegs alone are displaced to the tube loading zone of the ring spinning machine. Tube loaders forms part of the auto doffer which is provided with means for stacking empty conical tubes. The tube loaders are further provided with means for loading the empty conical tubes on to the empty pegs one after the other. The pegs loaded with the empty conical tubes are subsequently displaced underneath the spindle rail for exchange with the cops by the auto doffer of the ring spinning machine at the end of the cop built up cycle.

The outer diameter of the pegs corresponds to the spindle pitch distance and are designed with slots/recess at bottom, to accommodate the displacement member such as pusher provided with hooks to displace the pegs in the peg tray path on both sides of the machine. Pusher rods connected with pneumatic cylinders are employed under the peg trays at the bottom of the pegs over the entire machine length on both sides. Each pusher rods carries a plurality of pusher hooks provided to move the pegs during forward displacement and a plurality of stopper hooks for holding the pegs at their position during the backward displacement of pusher rods.

The accumulation of dust particles such as cotton fly prevalent in the textile mill get deposited on the peg moving area of the peg tray over a period of working of the machine. This obstruct the free flow of the pegs in the peg tray resulting in improper movement of the pegs as well as resulting-in the requirement of additional power for the displacement of the pegs in the peg tray. Frequent cleaning is required in order to keep the peg trays free from the accumulation of the fly which calls for additional effort. More over certain zone of the peg tray Is not easily reachable for cleaning.

OBJECTS OF THE INVENTION
The principal object of the present invention is to provide an arrangement that will keep the peg tray substantially free from the accumulation of the fly lint and other small waste matters.

Another object of this invention is to provide an automatic cleaning arrangement that will keep the peg trays free from the accumulation of dust, fly, lint and other small waste matters .

A further object of the invention is to provide an arrangement for the removal of dust, fly, lint and other small waste matters during the transportation of peg itself without the requirement of additional device and stoppage of the machine for cleaning of the peg trays.

SUMMARY OF INVENTION

According to one aspect of the present invention there is provided a peg tray cleaning arrangement in a textile machine, said arrangement comprising the plurality of pegs (1') arranged in between predetermined number of pegs (1) as a closed loop in peg tray assembly (2) are displaceable in between the tube loading zone and the cop unloading zone, for cleaning the dust, fly and other waste particles accumulated in the peg tray; wherein the pegs (1'} are provided with cleaning members {1g') on its bottom horizontal surface (1a'), top horizontal surface (1b') and the cylindrical guide surface (1c').

An another aspect of the present invention directed to said peg tray cleaning arrangement wherein the number of pegs (1') with cleaning members (1g'} in combination with peg (1) can be adopted as per requirement to ensure effective cleaning of peg tray assembly (2).

In accordance with another aspect of the present invention the said peg tray cleaning arrangement wherein the pegs (1') disposes the gathered dust, fly and other waste particles from the cleaning members (1g') at the curved portion of the peg tray assembly (2) and this facilitates the effective cleaning of peg tray during every cycle of doffing.

A still further aspect of the present invention of said peg tray cleaning arrangement wherein the cleaning of peg tray assembly (2) carried out by the pegs (1') itself automatically without use of additional device or energy and without stopping the machine.

The present invention and its objects and advantages are described hereunder in greater detail with reference to the following exemplary non-limiting illustrative figures.

Figure 5 of the drawings schematically illustrate the perspective view peg tray loaded with pegs and cleaning pegs of the invention.

BRIEF DESCRIPTION OF THE INVENTION

The peg (1,1') illustrated in figure 1 and 2 of the drawings comprises bottom horizontal surface (1a,1a'), top horizontal surface {Ib.lb'), cylindrical guide surface (Ic.lc'), cylindrical neck surface {1d,1d'), cylindrical stem surface {1e,1e') and cylindrical bottom recess surface (1f, 1f').

The peg tray assembly (2) illustrated in figure 3, 4 and 5 of the drawings comprises inner peg tray (2a) and outer peg tray {2b) shown fastened to the peg tray holder (3) which is rigidly fitted to the frame member (4). A plurality of peg tray holder (3) fitted to the frame member (4) along with a plurality of inner and outer peg tray (2a ,2b) constitute the peg tray assembly (2).

The inner peg tray (2a) and outer peg tray (2b) comprises horizontal surfaces (2a', 2b') and (2a", 2b") the distance between them corresponds to the height of the cylindrical guide surface (1c,1c') of the peg (1,1') with pre determined clearance. The inner peg tray {2a) and outer peg tray (2b) further comprises vertical surfaces (2a'", 2b'") and the distance (D1) between them corresponds to the diameter of the cylindrical guide surface {1c,1c') of the peg (1,1') with pre determined clearance while fitted on the peg tray holder (3). The fixing of the peg tray (2a, 2b) on the peg tray holder (3) give raise to a pre determined intervening gap (G1) for the passage of the cylindrical neck surface (1d,1d') of the peg (1,1') with pre determined clearance. The cylindrical bottom recess surface (If.lf) is provided for accommodating the pusher hooks which are operated by suitable means, for example by pneumatic cylinders for the displacement of the peg (1,1') in the peg tray (2).

According to the invention, a plurality of pegs (1') are arranged in between pre determined number of pegs (1). The pegs (1') being provided with suitable cleaning member (1g') such as bristles on its bottom horizontal surface (la'), top horizontal surface (lb') and the cylindrical guide surface (1c'). The empty conical tubes / cops as the case may be loaded on the pegs (1, 1') and are displaced in the peg tray (2) to facilitate the transportation of the pegs carrying the empty conical tubes underneath the spindle rail for exchange with the cops by the auto doffer of the ring spinning machine at the end of the cop built up cycle. Also the displacement of the pegs facilitate the displacement to the cops loaded on them to the unloading zone.

During the displacement of the pegs (T), the cleaning member {1g') attached to the pegs (1') wipe up and collect the dust, fly and other waste particles that got accumulated within the peg tray along with them. This facilitates the cleaning of the peg tray automatically with out the requirement of additional cleaning. The collected wastes may be extracted at the curved portion of the peg tray arrangement, where the pegs may tend to turn them selves slightly. The usage of the number of pegs (1') with cleaning element in combination with peg(1) can be adopted as per requirement to ensures effective cleaning of peg tray arrangement.
