Description

PREPARATION MACHINE FOR RECTIFICATION OF A TEXTILE MACHINE'S
ROLLERS
Technical Field of the Invention The present invention relates to a machine for separating rollers of a ring spinning textile machine from air guides connected thereto in an automated manner.
Background of the Invention
Various textile machines from a plurality of textile machinery manufacturers are presently operated in the country of the present applicant. It is known that ring spinning machines and in particular compact spinning machines provided substantial improvements in the yarn structure in recent years. DE10040073 discloses a ring spinning machine in which a condensing device is disposed between a drafting arrangement and a spinning device. In compact spinning, the drafting system has an aerodynamic condensing mechanism. The fibers at the delivery roller are additionally captured by means of a vacuum in the nip, and are compacted immediately afterwards. Fibers lie much closer together and parallel with each other. Therefore the spinning triangle is reduced to the compacting width. In order to condense the fibers after the main draft, the bottom delivery roller of the drafting unit has been replaced by a perforated drum. Inside each drum is a stationary insert with a specially shaped suction opening connected to the machine's suction system. The air current created by the vacuum condenses the fibers on their way over the perforated drum. The condensation zone fully controls the fibers all the way from the drafting system to the nipping line. An additional pressure cylinder (nip roller) prevents the twist from being propagated into the condensing zone. Compacting efficiency is enhanced by a specially designed air guide element.
Textile machines of the above-mentioned type require regular maintenance and rectification of the machine parts such as rollers. The air guide elements that are connected to the nip rollers need to be separated from said rollers for maintenance. According to the present invention a vibratory vessel is provided to advance rollers to an air guide separation position. Such vibratory vessels are known in the art. For example US3955336 discloses such a vessel.
The present invention proposes an automated process specially adapted for shortening maintenance procedure of a ring spinning machine in which rollers are separated from said air guides and fiber fluff is removed from around the axles of said rollers, which are arranged orderly to be reinstalled thereafter.
Objects of the Invention
One of the objects of the present invention is to provide an automated process in which rollers of a spinning machine are separated from air guides and fiber fluff is removed from around their axles and said rollers are arranged in order to be reinstalled thereafter.
Summary of the Invention The present invention proposes a machine having a vibratory feeding receptacle for receiving a plurality of rollers having air guides attached to the axles thereof. Said rollers are then advanced in conjunction with said vibratory feeding receptacle for delivering rollers from such receptacle through an article guide arrangement to an air guide separation device. Separated rollers are arranged in rows in a manner to be easily re-installed after maintenance. The apparatus further carries out a cleaning process for cleaning fiber fluff around the axles of the rollers. The present invention therefore substantially shortens maintenance procedure of a ring spinning machine.

Detailed Description of the Invention
Referring now to the figures outlined above, the present invention proposes a maintenance machine (11 ) for automated separation of rollers (22) of a ring spinning machine from the air guides (25) being connected to the axles of said rollers (22). For example compact spinning machines such as K44 and K45 manufactured by the company Rieter comprise such rollers (22) with air guides (25).
The maintenance machine (11 ) according to the present invention comprises a vibratory vessel (12) conventionally advancing a plurality of articles in a predetermined trajectory (13). Said trajectory (13) may conventionally have a gradually elevated peripheral base delimited by the outer wall of said vibratory vessel (12), leading to an exit opening (14). Said exit opening (14) itself leads to a conveyor (15), transferring said rollers (22) to a final position. The separation device (16) in Fig. 2 is shown in detail in Fig. 3.
Referring now to Fig. 3 and 4, the separation device according to the present invention comprises a carrier (17) in the form of two leafs (17a, 17b) being longitudinally hinged for receiving a roller (22) in its final position. A roller (22) is generally in the form of a barbell, i.e. with cylindrical portions (23) at both ends of the axle (24) and with an air guide (25) having planar plates (26) at both ends of a longitudinal rod (27), said rod (27) being releasably attached to the axle of said roller. A roller (22) transferred to the carrier (17) extends longitudinally on said carrier (17) along the hinge portion (18).
Said separation device (16) further comprises a lining plate (19) advancing back and forth on a shaft (20) to push a roller item on said carrier (17) against a vertical support (21 ) on the opposite side of said carrier (17). When a roller (22) is transferred to said carrier (17) by said conveyor (15), said lining plate (19) ensures -A- that the roller (22) is properly positioned. Further, an air guide orientation tip (28) rotates to take the air guide (25) portion of said roller (22) from a position on said carrier leaf (17b) to a position on the other carrier leaf (17a), while said roller (22) maintaining its position. In the event that said conveyor (15) transfers said roller (22) with said air guide (25) the latter being properly oriented, i.e. already on the carrier leaf (17a), said air guide orientation tip (28) will run idle.
When said air guide (25) is properly oriented with respect to the hinge portion (18), said lining plate (19) is for a second time advanced in the direction of said carrier (17) to push said roller (22) against said vertical support (21 ). Said roller (22) hence properly positioned, a separation head (29) is lowered to detach said roller (22) from said air guide (25).
Said separation head (29) according to the present invention is specially designed to have a tip portion with an intermediary surface portion (30) facing said carrier (17), said intermediary surface portion (30) being neighbored by two surface portions (31 and 32) at both sides thereof on an axis drawn between two carrier leaves (17a, 17b) perpendicular to said hinge portion's (18) axis. A first neighboring surface (31 ) on the side of the carrier leaf 17b has a greater surface inclination with respect to the longitudinal axis of the separation head (29) than that of the second neighboring surface (32).
Said separation head's (29) intermediary surface portion (30) presses on an opening portion (34) between the two arms (35) of said air guide (25) connecting the same to the axle (24) of said roller (22). Further an outwardly curved member (33) provides the effect that its curved tip limits movement of the roller (22) on said carrier (17) while the detached air guide (25) is allowed to fall in a separate receptacle.
The maintenance machine (11 ) according to the present invention further comprises a roller (22) axle (24) cleaning device. Fiber fluff accumulated around the axle (24) of the rollers (22) is cleaned by means of a cleaning device (39) according to the present invention. Fig. 7 demonstrates said cleaning device (39) cleaning fiber fluff around the axle (24) of a roller (22) lying on the carrier (17) of the separation device
(16). A cleaning tip (42) is installed on a first platform (40) of said cleaning device (39) such that it is rotatable around the axis A-A of a first motion inducing means
(43). Said cleaning tip (42) is also movable a certain distance laterally in the direction of the arrows B-B' (Fig. 8) by a second motion inducing means (44) while at the same time rotating around its own axis to enable said cleaning tip (42) to clean the axle (24) portion remaining between the two cylindrical portions (23) of the roller (22). Rotation of said cleaning tip (42) around its own axis provides the effect that the fluff is entirely drawn from around said axle (24). Said first platform (40) is also movable on a second platform (41 ) in the direction of the arrows C-C to draw said cleaning tip (42) near said separation device (16).
A roller transfer piston (36) on said separation device (16) then lowers said carrier leaf 17b to allow transfer of the roller (22) from said carrier (17) to a guideway (37) having a suitable slope for effecting orderly placement of said roller (22) on a roller carrier (38). While Figures 1 to 4 demonstrate the maintenance machine (11 ) according to the present invention with the separation device (16) alone, Fig. 7 and 8 demonstrate both separation and cleaning devices (respectively 16 and 39).
In sum, the present invention proposes a maintenance machine (11 ) for separating rollers (22) of a compact spinning textile machine from air guides (27) attached to the axles (24) of said rollers (22) and for cleaning fluff from said axles (24) of said rollers (22). Said machine (11 ) comprises a vibratory vessel (12) for receiving a plurality of rollers (22). Said vibratory vessel (12) has an opening (14) associated with a conveyor (15) transferring said rollers (22) to a position on a carrier (17) of a separation device (16). Said separation device (16) comprises a separation head (29) detaching a roller (22) from said an air guide (25). Said maintenance machine (1 1 ) further comprises a cleaning device (39) cleaning fluff accumulated around the axle (24) of the rollers (22).
