TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rolling coaster mechanism for nozzle tilting used in overhead travelling cleaner which is used for Ring frame in order to maintain the constant cleaning efficiency of the drafting zone and avoid the damages of the offend and gear end panel of the ring frame.

BACKGROUND OF THE INVENTION
The overhead travelling 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 has 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 drafting arrangement is the critical part of the Ring frame. The Ring frame converts the roving into yarn. 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. The width of the ring frame at both ends are higher when compare to the width of the drafting zone. In order to proper clean at drafting area, the overhead travelling cleaner nozzle should be placed very near to the zone for better cleaning efficiency. In this case, the nozzle hits the ends of the ring frame cabin which was provided at both ends of the machined while the overhead travelling cleaner running to the entire length of the machine and it causes the damage of the ring frame.

Therefore, there remain a need for a nozzle tilting mechanism for overhead travelling cleaner to overcome the above mentioned difficulties and shortcomings.

The present invention relates to a nozzle tilting mechanism for an overhead travelling cleaner comprising;
a tilting roller adapted to tilt in an angular direction, disposed in one end of a tilting plate pivoted in other end by means of a connecting rod;
said connecting rod coupled to said nozzle;
a pair of oscillating plates bridged by a tension spring, connected to a pair of mounting plates;
a pair of sliding roller sliding through said pair of oscillating plates; said rollers are positioned in both ends of a roller plate fixedly connected with said tilting plate;
wherein, when said tilting roller encounters any hindrance in its pathway, it tilts in an angular direction thereby tilting said tilting plate resulting in movement of said connecting rod, said connecting rod moving said nozzle in another direction to avoid any hindrance at the end of the spinning frames.

The travelling cleaner unit comprising a main chamber, blowing channel, round tube 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 travelling unit consists of main chamber (1) and nozzle tilting mechanism/ rolling coaster (5). Nozzle tilting mechanism/ rolling coaster includes oscillating plate (5) roller plate (6) tilting rollers (7) mounting plate (8) connecting rod (9) coupling (10) supporting frame (11) revolving duct (not indicated in figures), blowing reservoir (not indicated in figures), bottom coupling (not indicated in figures), timing pulley (not indicated in figures) and bottom connecting rod (not indicated in figures). The overhead travelling unit have both sides nozzle tilting (Rolling coaster tilting) mechanism equipped with the sliding roller arrangement. The rolling coaster tilting mechanism tilts 300-600 and sliding rollers are located outside the main rolling element. The tilting unit has the blowing reservoir and revolving duct which are directly connected with connecting rod. When the travelling unit reaches at end of the machines on both sides, it freely moves direction to avoid hindrances. The spring-loaded roller plate with tensile spring is located horizontally at center of the coaster assembly. The sliding rollers helps to slide the rolling element unit when the travelling unit reaches the end of the machine both head and tail ends of the ring frame.

The present invention of nozzle tilting (rolling coaster tilting) mechanism clearly provides following outcomes:

1. Nozzle location and position not changed.
In this invention, the nozzle tilting (rolling coaster tilting) mechanism is introduced in Overhead travelling cleaner at both sides. The rolling coaster elements are sliding on the guide plate which is in surface contact with the angle and sliding to the opposite direction by the tilting roller which is assembled with the attachment pipe. The tensile springs are placed with oscillating plates. When the travelling cleaner reaches at end of the machine, the rolling coaster assembly mechanism actuated by tilting roller and its oscillating plate, one end of the connecting rod is directly connected with timing pulley and other end is coupled with tilting plate assembly. The timing pulley assembly is directly connected with revolving duct and blowing reservoir. When the cleaner is running, the blowing reservoir along with the nozzles are tilted out and then return to its original position. Thus, there is no hitting to surface of the machine. Because of this invention, the nozzles which are fixed with the blowing reservoir, is not disturbed for its next cycle of operation.

2. Eliminate the struck -up sliding movement
By using the rolling coaster tilting mechanism, it acts as a surface contact on the guide angle and it gives the perfect sliding operation for every cycle of operation. Due to the rolling contact, the dust will not enter into the connecting rod and subsequently the free movements are ensured.

3. Eliminate the damages of machines
If the travelling machine runs without rolling coaster tilting mechanism, the nozzle and hoses hits in every cycle of travelling and it creates the marking and damages on the surface at both offend and panel end of the machine. By using this mechanism, the problem can be eliminated.

4. Improved in quality of yarn
To reduce the weight per unit length, the roving is passed through three to four drafting rollers to attain differential speed. It is the most important part in the ring spinning process. 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 is 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 blowing by use of overhead travelling cleaner is also an essential part to improve the quality of yarn. By using rolling coaster tilting mechanism, the blowing reservoir with nozzle is provided near to the drafting arrangement to blow on to remove the fly and fluffs accumulation continuously without hitting the machine. Due to the blowing reservoir, the constant pressure also maintained and delivered into the drafting zone.

5. Maintenance cost
The installation of rolling coaster tilting mechanism is used continuously when the travelling cleaner is reached at end of the railing without any disturbing and mis location of nozzles. We can eliminate the maintenance cost and time to adjust the blowing pipe and nozzles in every cycle of operation.

6. Improvement in performance.
By providing the Rolling coaster tilting mechanism in the Overhead travelling cleaner and it improves the cleaning efficiency of the machine. Wastes accumulated inside drafting rollers and other critical parts of the ring frame creates the reduction in delivery of yarn with imperfection. Due to the lack in improper blowing on this part, the overall machine cleaning efficiency also reduces. Cleaning efficiency of this invention has been improved from the critical parts by providing the blowing reservoir and nozzles near to the parts of the ring frame.

Advantages of the present invention.
1) Constant blowing pressure is maintained on drafting and parts.
2) Improve the cleaning efficiency on drafting rollers.
3) Quality of yarn is improved.
4) Average cleaning time is less.
5) Easy to assemble and less construction cost
6) Eliminate the damages of ring frame.
