Definitions
- the present invention relates to a device for Control of the thread lever of a braiding machine according to the generic term of claim 1 and a braiding machine according to the preamble of claim 9.
- limit speed One of the key parameters of a braiding machine is the limit speed. This depends on several factors namely the type of control of the thread lever and / or the Type of gear coupling between the drive elements, the reversing gear and the coil carriers.
- the thread lever must on the one hand above the weft bobbins be pivoted and on the other hand below the warp spools.
- the upper end of the thread lever must be over the Warp spools go that the associated weft can be taken over by a thread guide plate, which the Defines the area of movement of the weft thread above the warp thread.
- the control of the thread lever is usually controlled by the Combination of a circular, closed cam track with the associated sliding block.
- the cam track is arranged outside of that surface of revolution which the thread lever during the rotation of the weft spools circles.
- the cam track therefore covers the entire braiding machine.
- the reverse gear is on braiding machines with central tube essential part to the upper coil former one counter to the lower coil carriers Imprint rotary motion around the central tube.
- the advantage of this partial invention is that with a more compact design of the braiding machine, the weft and the warp spools are more accessible.
- the thread lever also executes on this surface of rotation the swivel movement that interweave between Warp and weft leads.
- the relative speed becomes on the one hand reduced between sliding block and curved track, because the circle of intervention between the sliding block and Cam track is on a smaller radius than if the Cam track would be arranged outside the rotation circle.
- the target group should be sought between the sliding block and the curve track within the inner circle of the circumscribed circle. This offers the additional possibility of the swivel axis of the To store the thread lever in a hole in the gear housing, where the sliding block and curve track can lie in an oil bath.
- the cam track can be used to simplify the construction be arranged on a ring console, which as a separate Component is rigidly connected to the central tube.
- the pivot axis can be tilted in such a way with its end facing the central pipe to the braiding point is inclined. This is practically the exit end of the meant to braid material from the central tube. This enables an effective swiveling movement over the warp thread bobbins and under the warp spools with low forces.
- the relevant critical angle - measured to the normal plane the central axis - is 45 degrees. This results in being permissible Angular range: 45 °> alpha> O °.
- this partial invention is based on the reverse effect, which is caused by the in the internal ring gear revolving pinion is caused.
- the internal ring gear is certain, the inner circumferential pinion is supported its point of engagement with the external ring gear with a small Pitch circle diameter on the output side of the gear unit, which causes the reversal of the direction of rotation.
- this planetary gear arrangement allows adjustment the speed ratios required for the braiding process are necessary.
- the figures show a braiding machine 1 in a schematic manner View.
- a central tube 3 is rigid on a machine frame 2 struck.
- the central tube 3 serves in the lower area of the receptacle a gear housing 5, which with a gear housing mounting 6 is rotatably arranged on the central tube 3.
- the gear housing 5 is rotated imprinted, which also with the gear housing 5 connected slideway carrier 7 performs.
- lower Bobbin carrier 8 In the lower area of the gear housing 5 are lower Bobbin carrier 8 arranged, each having a weft bobbin 9 wear.
- the weft thread is indicated by one not specified Breakthrough in the thread lever 10 and runs from there a deflection device 13, which is located at the upper end of the Thread lever 10 is located.
- the thread lever 10 is pivotable about a pivot axis 11, which is movable in a pivot axis bearing 12.
- the weft bobbins While the long goods 15 only in the vertical upward direction is promoted, the weft bobbins perform one Rotation in a predetermined direction of rotation around the central tube 3 around. This rotary movement is predetermined by the drive 4.
- a reversing gear 20 which consists of a gear ratio 23 and an idler gear 21 exists.
- the reverse gear serves the purpose of rotating the Gear housing 5 in an opposite to the first direction of rotation Convert direction of rotation and then the warp thread carriers 18 give up, each a warp bobbin 19th exhibit.
- the warp thread carriers 18 thus move in the direction of rotation opposite to the first direction of rotation 29a 29b around the central axis 50 and are thereby from the Slideway carriers 7 out, as well as the warp thread carriers 18 are only provided in segments.
- the reversing gear 20, which serves as essential component has the intermediate gear 21.
- the idler gear 21 is via the idler gear shaft 22 rigidly connected to the slide track carrier 7. It is about here around a bevel gear, which on the one hand with the warp thread carrier 18 and on the other hand with the inner ring 16 in a form-fitting manner Intervention is.
- the inner ring 16 is independent from the gearbox and also rotatable on the central tube 3 stored.
- the inner ring bearing 17 thus enables the Inner ring 16 independent of the transmission housing 5 around the central tube 3 turn around.
- gearbox 5 and inner ring 16 different Must have revs is according to 1 to 3 a translation stage 23 is also provided is supported on a ring bracket 24.
- the ring bracket 24 is rigid with the central tube 3 connected.
- the gear ratio 23 consists of an internal ring gear 25, rigid with the fixed ring console 24 connected is.
- the internal ring gear faces within the gear ratio 23 the largest pitch circle diameter.
- a pinion 26 rotates, which opens a rotational axis 28 is rotatably mounted.
- the revolving axis 28 is rigid with the gear housing 5 connected.
- the pinion 26 is consequently both with the internal ring gear 25 large pitch circle diameter as well as with the external ring gear 27 small pitch circle diameter in constant engagement and turns around together with the gear housing 5 the central axis 50 and on its orbital axis 28 because it by engaging the rigid internal ring gear 25 with its Gearing is forced to do so.
- the pivoting movement 35 takes place between the lower ones Pivot positions 33a and upper pivot positions 33b, while the thread lever 10 is guided around the central axis 50 becomes.
- Fig. 3 shows in addition, the sliding block sits 31 on a guide lever 44, which is of the geometric Pivot axis 45 of the pivot axis 11 has a distance.
- the Pivot axis 11 mounted in the gear housing 5.
- the cam track 30 sits in an outside of the Rotating surface 32 lying area of the braiding machine and points on the lateral surface facing the central tube 3 an engagement zone for the sliding block running there 31 on.
- the cam track 30 is part of a braiding machine comprehensive maturity, which is as compact as possible Design of the reversing gear in the embodiment according to 5 can have a relatively small diameter.
- the geometry of the gear housing 5 according to Figure 5 is not to scale.
- the actual volume of the gearbox 5 is considerably smaller and thus leaves the inside diameter of the tire with the cam track 30 accordingly shrink.
- the respective path-time law of the thread lever movement is predetermined by the basic contour of the thread guide plate 34.
- both the sliding block 31 and the cam track 30 lie within the surface of rotation 32 which the thread lever rotates around the central axis 50 circumscribes.
- the sliding block 31 and the cam track 30 within the inner end 36 of the Swivel axis 11 lie.
- the circle of intervention lies between sliding block 31 and curve track 30 within of the circle that from the inner end 36 of the Swivel axis 11 is circumscribed.
- Figures 1 and 4 show that the pivot axis 11 rotatable in a bore 37 of the gear housing 5 is stored.
- the gearbox is also intended to mount the gearbox on the central tube and on the outer circumference of the inner ring 16 and also the pivot bearing of the pivot axis 11 seal on the gearbox housing with radial seals 39a-c, the oil level 38 within the gear housing 5 Realize that sliding block 31 and cam track 30 in an oil bath lie.
- the oil-tight closed gear housing 5 can if necessary, be provided with a suitable drain plug.
- cam track 30 in turn on the ring bracket 24 attached, can thus be a wear-free and environmentally clean Permanent lubrication between sliding block 31 and Generate cam track 30, associated with the advantage clearly higher relative speeds and thus higher speeds for the braiding machine.
- the curve track be inclined by the same angle of inclination so that the Sliding block with the largest possible contact to the Walls of the cam track 30 attacks.
- This measure serves to compensate for changes in voltage in the weft, caused by the swiveling movement of the Thread lever 10 between the lower pivot position 33a and upper pivot position 33b are caused.
- This measure serves to avoid any bending moments on the bearing of the pinion axis, which together with the gear housing 5 rotates and therefore called the rotation axis 28 becomes.
- the idler gear sits on an idler gear shaft 22, which is rigidly connected to the gear housing 5 and lies above the radial plane 48, in which inner ring gear 25, rotating pinion 26 and external ring gear 27 with one another comb.
