, Description:
FIELD OF THE INVENTION
The present invention relates to an overhead travelling cleaner in a textile machine. Particularly the present invention relates to an automatic electro-mechanic control mechanism for blowing pipe turning angle in overhead travelling cleaner.

BACKGROUND OF THE INVENTION
The cleaner is used in the spinning industries to collect the break yarn waste and fly dust from the machine and floor. The overhead travelling cleaner have blowing and suction hoses at both sides to clean the machine and deliver collected waste into the collection box which is fixed at end of the Ring frame. The piecing operation is the critical activities for Ring frame productivity. The Ring frame converts the roving into yarn and the drafting arrangement has four rollers to reduce the weight per unit length, in which roving is passed through these rollers to attain differential speed.

In Ring frame, the cotton is converted into yarn as the resultant yarn is produced in it. Yarn breakages are frequent occurrences due to the some of the parameters of yarn and spinning machine and the same is unavoidable in ring frame which is a major concern to be addressed then and there. Yarn breakage has to be continuously monitored by the monitor system and manually and broken yarn has to be pieced manually by the workers. The Ring frame machines are long and workers continuously monitors the yarn breakages and perform manual piecing of broken yarns round the clock walking along the pathway along the aisle of the ring frames. After piecing the broken yarn manually, yarn spinning sequence will be restarted then and there to avoid production downtime and yarn wastage.

For that, the overhead travelling cleaner nozzle can be placed very near to the zones of the ring frame for better cleaning efficiency. In this case, there is no need for the nozzles expansion /retraction arrangement due to there is no changes in the width of the Ring frames. The manual piecing has been done without any hindrance of the overhead travelling cleaners’ movement. Now a days the automatic piecing unit are developed by few manufacturers in spinning industry. The automatic piecing unit is a movable unit in vehicle form with wheels / rails / guides and stops in front of the respective spindle position which require piecing assistance. The piecing unit in general moves longitudinally over the machine frame aisles. Before initiating piecing operation, the piecing vehicle stops in front of the spindle and then the broken yarn end which is available in the spinning cop has to be found and picked. Normally in some types of yarns, the broken yarn gets entangled in the cop and it is not visible to naked eye. Also, it is very difficult for the workers / automatic piecing unit to find and pick the entangled broken yarn end from the cop to perform subsequent piecing operation. Now a days the few manufacturers have developed the separate automatic piecing unit and the same is fixed at both sides of the ring frame on its railing which is arranged at bottom of the ring frame.

The ring frame consists of two piecing units at both sides and the width of the ring frame is more compare to normal frame. Therefore, the standard overhead travelling cleaner cannot be used due to the blowing and suction pipes, nozzles are prone to hitting the piecing units and it will not allow to run the overhead travelling cleaner to the entire length of the machine and it causes the damage of both piecing units and overhead travelling cleaner.

Therefore, there remain a dire need to provide a solution for the above-mentioned technical problem by providing an improved arrangement for rotating / swinging mechanism of the blowing pipe when the overhead travelling cleaner reaches at automatic piecing unit to enable automatic rotation of the blowing pipe and nozzles in over hear travelling machine.

The travelling cleaner unit comprises a main chamber, blowing and suction pipes, Motors, fan and rollers. The main travelling unit have suction and blowing tube on both sides of the cleaning device. The body includes bottom plate, middle plate, middle assembly, top cover and fan. The dust collection basket is permanently installed at one end of the guide rail. Near end of the two guide rails are provided with angle plates to push the rollers.

The subject invention lies in a travelling cleaner system, referring Figures 1, 2 , 3 and 4 for cleaning textile machinery arranged in a textile mill comprising an overhead travelling cleaner unit (12) arranged along longitudinal axis of said textile machinery; including at least one suction pipe (5) and at least one blower pipe (3) on both sides of the cleaner unit (12); an automatic electro mechanic rotating/ swinging mechanism for rotating / turning of the blowing pipe; and at least two proximity sensor and three obstacle sensors for sensing signals from position sensors located at predetermined points on said machinery and transmitting said signals to a PLC Controller;
characterized in that the automatic electro mechanic control mechanism includes a movable bearing assembly with plate (6) operated by the stepper motor for rotating/swinging an angular gear assembly adapted to change the position of blowing pipe from 0 to 90 degree;
wherein said PLC Controller is configured to drive said stepped motor when said proximity sensors and obstacle sensors signals presence of any hindrance in the pathway of the cleaning unit, to further rotate said angular gears thereby rotating /swinging said movable bearing assembly with plate (6) resulting in the rotation / swinging of said at least one blowing pipe which is in physical contact with said assembly plate.

According to one of the embodiments of present invention, said automatic electromechanics control mechanism for blowing pipe turning/swinging operation comprises a stepper motor, an angular gear arrangement connected on a movable bearing assembly with plate and a signal sensor arrangement. During the process, the movable bearing assembly plate holds said angular gears with a slotted plate and the stepper motor is rotated in a direction opposite to the location of piecing units. Said stepper motor is adapted to rotate in clockwise and in anti-clock wise direction. During a reverse rotation of the gear, the mounting bearing assembly plate makes the rotary movement to change the direction of rotation of the at least one blowing pipe. When the travelling cleaner moves away from the piecing unit the blowing pipes gets back to maintain the standard width of the travelling cleaner unit. In order to avoid the hindrance effect on both sides of the piecing unit, the electro mechanic operating mechanism operate the gear mechanism to rotate the blowing pipe from the centre axis at specified distance by the electronic signal control.

In one of the embodiments of present invention, the rear ends of at least one suction pipe (5) and at least one blowing pipe (3) of each side of the travelling cleaner unit include nozzles for sucking and blowing air in said machinery.

In another embodiment of present invention, said at least two proximity sensor (11) and three obstacle sensors are located vertically at center of said movable bearing assembly plate (6).

In yet another embodiment of present invention, said angular gear assembly (2) is in physical contact with said movable bearing assembly plate (6) by means of a surface plate (7).

In a preferred embodiment of present invention, said movable bearing assembly plate (6) is in physical contact with said at least one blowing pipe (3) by means of a turning bush (8).

In a preferred embodiment, said automatic electro mechanic control mechanism is provided in both sides of the cleaner unit.

In another embodiment of present invention, said angular gear assembly (2) is directly connected with said stepper motor (1) shaft.

When the cleaner is running, the blowing pipe along with the nozzles are turned out and then return to its original position and there is no hitting to piecing unit. Because of this invention, the nozzles which are fixed with said blowing pipes are not disturbed the any direction and position for its next cycle of operation.

By using the turning bush arrangement and its mechanism, it gives the perfect sliding operation for every actuation of the stepper motor. Due to the surface contact, the dust will not enter into the surface of blowing unit and subsequently the free movements are ensured.

If the travelling unit runs without this automatic control mechanism, the nozzle and pipes hit in every cycle of travelling and it creates the marking, damages and it will not allow the working function of piecing unit. By using this mechanism, the problem can be eliminated.

By providing this automatic control mechanism in the Overhead travelling cleaner it improves the cleaning efficiency of the machine wherever using the piecing unit. Cleaning efficiency of this invention has been improved from the critical parts by providing the adjustable movement of the blowing pipe.

The automatic control mechanism for turning of blowing pipes also improves the quality of yarn. The drafting directly influences the strength and evenness of the yarn. The ring frame uses 3 x 3 drafting, with three top and three bottom rollers while the middle rollers are covered with apron. The top rollers coated with rubber are negatively driven, hence they have no drive. The bottom rollers are coated with steel and are positively driven. The top rollers are driven by the bottom rollers with the help of pressure arm. The pressure arm applies pressure on the top rollers which influences the bottom rollers to start moving. Drafting system makes important role at yarn quality and performance of the machine. It is essential to control fly liberation and fluff accumulation in drafting arrangement, not just for the life of rollers at drafting zone but also to maintain yarn quality. Some useful measures to control fly and fluff generation are required. Remedies for inadequate moisture in cotton and several measures to control fluff accumulation are considered before process in spinning machine. Effective distance of blowing through nozzle by use of overhead travelling cleaner is also an essential part to improve the quality of yarn. By using automatic electromechanical controlling mechanism, the blowing pipe with its nozzles are provided near to the functional parts of the Ring frame to blow on to remove the fly and fluffs accumulation continuously without hitting the piecing machine.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from scope of the invention. It is intended that present invention covers such modifications and variations disclosed in the description.
