Definitions
- the present invention relates to a driving device for an automatic maintenance machine on spinning or twisting machines, this automatic maintenance machine traveling on a rail system to work stations of the machine and having to go through a track curve on the front side of the machine as a result of necessary changes on the machine side.
- the maintenance machine is a closed assembly which, for technological reasons, has to be positioned in a movement plane at locally different locations on the textile machine.
- the maintenance machine is mounted on a running rail system.
- the running rail system which consists of the outer and inner running rails, is attached to the machine frame by means of supports.
- the maintenance machine is supported on the inner running rail with guide rollers attached to a boom, while the running and guide rollers of the automatic maintenance machine are guided on the outer running rail.
- the undercarriage of the automatic walker must therefore ensure precise guidance to the work stations of the textile machine and when cornering on the outer track.
- the critical transport movement of the maintenance machine occurs when the track is traveling. As a result of the relatively high speed with large weight and volume of the maintenance machine, there is a braking and restless transport movement when cornering.
- an impeller is rigidly arranged on both ends of the chassis of the maintenance machine, where the fork of the impeller is rotatably supported by means of ball pins.
- the formation of a flange on both sides is required on the impellers to ensure the directional stability during transport.
- this impeller is equipped with wheel flanges on both sides, which are rotatably supported against each other independently of the impeller. Nevertheless, this solution does not avoid wear at the friction points and spontaneous braking effects.
- Another device according to DE-OS 38 33 739 dispenses with flange members on the impeller.
- three guide rollers with axes parallel to the steering axis of the wheel are arranged on the sides of the track.
- a special feature is that at least two guide rollers run on one edge side of the curve in different radial planes and the curve has two different radii. 'However, since further comprises at least two running wheels are rigidly coupled over a defined distance miteinenander, a sliding friction to the Laufziern- is maintained, the advantage not have sufficient quiet running of the automatic maintenance device garan ⁇ .
- the maintenance machine has a chassis above the support rail, which has guide rollers on its underside, which hold the maintenance vehicle on the rail. It is provided that a chassis is arranged on each of the two edges of the chassis located transversely to the rail.
- the chassis contains the support wheel, which is mounted in a movable fork.
- the axis of the pivot bearing runs in the central vertical plane of the support wheel.
- guide wheels are arranged in pairs on both sides of the rail wall, the axis of rotation of which is parallel to the axis of the rotary bearing.
- the pivot bearing is connected to the pivot bearing via the connecting web.
- the swivel bearing is in turn connected to the chassis. When the running gear moves linearly, the connecting web is locked on both sides parallel to the direction of travel.
- a rigidly fixed stop from the chassis prevents the connecting bridge from swiveling transversely to the rail and away from the machine.
- the chassis also includes a feeler wheel, which is connected via a linkage that runs vertically to the pawl and is rotatably mounted at the intersection with it.
- a cam the length of the distance between the two feeler wheels is arranged on the side of the track facing away from the machine and along the direction of travel.
- the pivot bearing is connected to a pivot bearing via a connecting web, so that the support wheel is enabled to pivot horizontally with respect to the longitudinal axis of the chassis.
- this rotatable change in position is only made possible when, at the beginning of the track curve, the first feeler wheel lifts the pawl upwards by forced movement of the cams via the linkage rotatably mounted on the pawl, sets the pawl on the narrow side of the connecting web and thus releases the locking mechanism on one side, so that the support wheel of the curved track can pivot relative to the chassis.
- auxiliary roller and auxiliary rail support the maintenance machine in this transition zone of the track and prevent a jerky transition to the track arch.
- the arrangement at the entrance of the track arch is installed in the same way at the exit of the track arch in order to carry out support and locking functions there.
- the following feeler wheel of the second running gear slides on the cam and likewise releases the one-sided locking of the connecting web for the associated supporting wheel, and the supporting wheel can move according to the rail curvature from the linear direction of travel and relative to the driving ⁇ frame. Swivel, the roller of the chassis rolling on the inclined plane of the auxiliary cam. Depending on the radius of curvature, the subsequent key wheel slides prematurely from the web of the cam. Therefore, the outer edge of the middle of the upper web of the cam is chamfered to make it easier for the cam to leave the web prematurely.
- the respective pawl remains open until the corresponding feeler wheel hits another cam at the track curve exit and raises the pawl in question and locks it.
- FIG. 1 View of the chassis I with chassis
- FIG. 3 Overall view from below on track with chassis, chassis I and chassis II
- Figure 4 Arrangement for locking the connecting web of the rotary and pivot bearings
- FIG. 5 Bottom view of the chassis to show the mechanism auxiliary rail and auxiliary roller
- FIG. 1 illustrates that the maintenance machine (15) has to be guided on a track curve at a rapid speed with the lowest sliding friction and without tilting the undercarriage in order to change the machine side.
- FIG. 3 shows essential features of the invention.
- the swiveling of both the chassis I and the chassis II with respect to the chassis (1) is documented in FIG. 3.
- the example of the chassis (1) shows that this is in the track curve in the plane of the track surface relative to the longitudinal axis of the chassis ( 1) can pivot by a swivel angle ⁇ .
- Chassis I and chassis II are unlocked. This was only possible because by means of cams (7) and a retracting feeler wheel (6) via the linkage (11) the one-sided locking of the connecting web (9) was unlocked by the pawl (10). This also applies to chassis II.
- the cams (7) which cause the pawl (10) to unlock when the feeler wheel (6) is opened, are attached in the linear track wall section before and after the end of the track curve.
- the direction of travel of the maintenance machine is freely selectable.
- the feeler wheel locks its connecting web first via the latch mechanism of the respective front undercarriage.
- the connecting web of the following undercarriage is also locked via its feeler wheel and ratchet mechanism.
- the chassis swivels with the front by the swivel angle ( ⁇ ) such that the subsequent feeler wheel already leaves the cam laterally after unlocking the second connecting web and the edge of the cam is chamfered to facilitate the transition.
- Figure 4 shows how the connecting web (9) is locked in cross section by the stop (8) and the pawl (10). With Unlocking, the latch nose is stored on the back of the connecting web (9). The width of the connecting web (9) is dimensioned such that the pawl nose cannot leave the connecting web (9) at the maximum swivel angle ⁇ .
- the connecting web is relocked by leading the connecting web to the stop (8) again as the vehicle begins to drive straight ahead, and the pawl nose is guided beyond the back of the connecting web and engages in the locking position.
