DESC:TECHNICAL FIELD OF THE INVENTION
The present invention relates to the waxing device for textile machines. Particularly the invention relates to the waxing device for yarn winding arrangement of textile machines like cone winding, cheese winding and air jet spinning machines.

BACKGROUND OF THE INVENTION
In textile yarn winding machines, generally a wax or paraffin layer is applied over the running yarn before the said yarn is wound on the package to reduce the coefficient of friction while processing the yarn in applications like knitting. In a wax or paraffin coating device, the yarn is to be provided with said wax coating when it runs over a fixed waxing element which is rotatably mounted, whereby its rotational axis is perpendicular to the running direction of the yarn. The delivered yarn is guided over the front of the waxing element so that a thin layer of wax is applied to the yarn. For an even and uniform wax application, it is necessary that the waxing element remains always in the same position relative to the course of the yarn. In order to ensure this, the waxing element is mounted on its rotational axis so that it can be displaced in axial direction. A stop is provided in that case against which it is pressed in the direction of the yarn by means of a spring. The contact between the yarn and the waxing element is on the front of the latter.

In the waxing device according to US patent publication US5879455A, rollers are used as path limitation means, which, rolling laterally on the end face of the waxing element, specify the respective working position of the waxing element. The rollers are mounted in this case, with their rotary pins are mounted wherein the holding sleeve supported eccentrically in a hole of a bearing housing. By adjusting the angular position of the holding sleeve in the hole of the bearing housing, the position of the path limitation rollers, and therefore the axial working position of the waxing element can be adjusted.

Furthermore, in waxing device according to German patent publication DE102006018838, plurality of path limitation means can be adjusted in defined manner on pivot pin. The pivoting flap has a plurality of stops of different heights defining specific working positions of the paraffin wax body.

In the known waxing devices, there is a drawback that the wax body is relatively freely arranged in the installation position because of the complicated and unsecured construction and therefore tends to soiling owing to fibre fly. Moreover, the known waxing devices, lead to non-uniform application of wax over the yarn. Also the known waxing devices are designed in a relatively expensive manner.

OBJECTS OF THE INVENTION
The object of the present invention is to overcome the above-mentioned drawbacks and to provide an adjustable waxing apparatus that can be fixed in various working positions to offer an even and effective wax application on the yarn.

It is another object of this invention to provide an adjustable waxing device that provides simple construction and offers an easy replacement of wax element.

Yet another object of the present invention is to provide an adjustable waxing device that provides great stability to the wax holder to keep the wax element in a secured position.

The present invention discloses a waxing device for winding machines comprising a stationary housing; a wax body is placed inside the stationary housing through a wax axle on the wax holder, the said wax holder is pushed forward by spring against the running yarn and is driven radially and axially by the motor wherein a setting ring which acts as a adjusting means is mounted on the stationary housing with the screws.

The waxing device according to the present invention is represented in figures 1 to 3. The said waxing device comprises stationary housing (2) in which the paraffin wax body (1) is inserted through wax axle (9). The motor (4) is provided whose shaft acts as a wax axle (9) is used for driving wax (1) mounted on a wax holder (14). The setting ring (3) is mounted on the stationary housing (2) with the screws. The limiting lid (5) is hinged on the housing (2) and is opened in loading position for inserting new wax body (1) and is closed in operating position. The said limiting lid (5) acts as the stop for the wax body (1) in which wax body (1) rest its end face. The plurality of magnetic catch (6) is provided on the inner side of the limiting lid (5) and it is used to stay intact with the steel setting ring (3) in operating position. The lid locator (7) is provided for locating the limiting lid (5) on the housing (2). The traverse guide (8), made of ceramic or steel, is provided on the upper part of the housing (2) for guiding the yarn.

According to the invention, as shown in figure 4, the setting ring (3) consists of three combinations of variable depth holes used as the path limitation means for wax penetration control on the running yarn. The required amount of penetration can be achieved by positioning the setting ring (3) such that the setting index position number (11) in bottom is visible through the limiting lid (5) as shown in figure 5.

1. The position number 1 (Pos 1) corresponds to the combination of three holes each separated at 120° from the other hole with same depth (i.e. 0.5 mm) is to be mounted on the housing using the screws.
2. The position number 2 (Pos 2) corresponds to the next combination of three holes each separated at 120° from the other with same depth (i.e. 1 mm).
3. The position number 3 (Pos 3) corresponds to the third combination of three holes each separated at 120° from the other with same depth (i.e. 1.5 mm).

And therefore the wax contact will be more in position number1 when compared to position number 2 and is minimum at position number 3, said setting index position number 1 will be having 1.5 mm paraffin wax body extending between the traverse guide (8) and limiting lid (5) and is applied on the running yarn and similarly the setting index position number 2 and 3 will be having 1mm and 0.5mm of the wax body respectively extending between the traverse guide (8) and limiting lid (5) and is applied on the running yarn.The setting ring (3) is mounted on the ring mounting position (10) on the housing (2) with screws with the required setting based on the yarn type.

The wax (1) is placed inside the housing (2) through the wax axle or motor shaft (9). The wax holder (14) with spikes is provided for receiving the wax body (1). The wax holder (14) is pushed forward by the spring (15) present inside the housing (2). The said spring support (16) is provided for supporting the spring (15) such that the spring (15) pushes the wax holder (14) forward which in turn drives the wax body (1) axially towards the limiting lid (5). The wax holder (14) is mounted on the motor shaft (9) so the wax holder (14) rotates when the motor (4) runs, resulting in rotating the wax body (1). The wax body (1) is driven radially and axially with the aid of the motor (4) and the spring (15) respectively. Said continuous pushing and constant rotating action provides a constant pressure of wax surface onto the running yarn. So that the required amount of waxing is applied uniformly on the yarn surface, before the yarn is being wound on the package.

The sensing magnet (12) and the wax exhaust sensor (13) is provided on the waxing device for monitoring the wax body (1). The sensors (13) are connected to the winding machine computer. The wax exhaust sensor (13) is provided inside the stationary housing (2). The waxing device on applying the wax (1) to the running yarn, tends to move forward by the spring force and when it reaches near end position,the sensing magnet (12) placed on the wax holder (14) is sensed by the wax exhaust sensor (13) and the sensor transmits the signals to the winding machine computer which in turn actuates the alarm at set time period on both winding module indication lamp and HMI (not shown) before stopping the winding module.
