Definitions
- the invention relates to a disc brake for textile threads, with a vertical hollow plate axis, the two Brake plate supports and in a attached to a brake carrier Bearing plate swiveling, which supports the plate axis above the brake carrier and below the upper one Brakes outside surrounds.
- EP 0 529 429 A1 is known.
- the well-known plate axis is oscillating pivotally driven so that there is a brake plate or move both brake discs of the disc brake back and forth. It should be achieved that fluff and the like. in the field of Can not lock the brake plate, as that when stationary Brake actuators or rotary brake actuators of the would be the case.
- the accumulation of fiber would impair the braking force. This can be done with the disc brake with the aforementioned Features happen in a variety of ways. If form fiber accumulations in the hollow of the hollow plate axis, this can lead to the top plate and the above arranged load element can be raised. Thus breaks the adjustable thread tension together.
- the one from this disc brake braked textile thread does not have the required Tension and, as a result, of a variety of textile threads with a winding machine pulling off a creel wound up to low tension. A corresponding one is created Fault in the winding structure and possibly also the Unwinding operation, e.g. when the winding machine is stopped.
- the invention is therefore based on the object of a disc brake to improve with the features mentioned at the beginning, that pollution and especially internal pollution be avoided.
- the plate axis and the bearing plate has at least one air duct or have, on the one hand connected to a compressed air source and on the other hand at fiber dust collection points in the Area of the saucer opens.
- the plate axis and the bearing plate have an air duct with which under the saucer can be blown.
- the saucers are specially designed for the disc brake in the area of their plate axis and in the area of their Bearing plate. This allows the fiber dust below to blow off the saucer at those points which he caused by a global blowout of the disc brake above or through a global blowing of the disc brake from could not be removed below.
- the blowing of the disc brake in the area of the saucer, the construction of the disc brake be adjusted. In principle, therefore, it is possible for everyone to keep any part of the disc brake free of fiber.
- the disc brake Form it is important that this is essentially rotationally symmetrical is.
- the disc brake Form it is advantageous to use the disc brake Form so that the air duct has a sealed ring groove the plate axis is, the vertical, directly under the saucer has opening openings.
- the ring groove of the air duct can be at all required points on the disc brake be blown. That will be chosen by a suitable one Positioning of the outlet openings reached.
- the disc brake designed so that the underside of the saucer and the cavity of the plate axis with each other in terms of air flow are connected.
- the disc brake can be designed so that a Flexible, porous saucer ring from the outlet openings of the air duct is blown with compressed air. As a result, dust will accumulate in the area of this ring avoided. The ring cannot harden. Such a through Dust accumulation caused by hardening of the ring would result cause the saucer to no longer or no longer adequately could dodge if thread thickening or thread knots run through the brake plate. A hardening of the ring would lead to thread breaks. The risk of thread breakage is reduced by the compressed air cleaning of the porous ring avoided.
- the disc brake is designed so that on the ring groove radial, outside of that supporting the saucer Blow openings opening between this and the bearing plate connect, the disc brake is not only on the disc axis side cleaned, but also in the area between the plate axis and the surrounding bearing plate. The structural Effort due to the additional blow openings is low.
- the disc brake In order to supply the annular groove with compressed air from the outside, the disc brake is designed so that the air duct in the Bearing plate radial supply air slots for air supply in the Has ring groove. About the number and distribution of the air vents the compressed air supply to the annular groove can Cross-sectional dimensions without significant throttling losses be supplied.
- the disc brake designed so that the air vents with blow holes are connected, which is outside the supporting the saucer Blow around between them and the bearing plate.
- the plate brake is designed so that the Ring channel of the bearing plate with the ring groove of the plate axis over the supply air slots are connected. There is a structural simple arrangement.
- the disc brake can be designed so that in one horizontal brake carrier intended for further disc brakes an air feed line is arranged, the vertical Connection holes to the ring channels of the bearing plates of the Has disc brakes. It becomes the central compressed air supply achieved a variety of disc brakes, which a common Air supply line is assigned.
- the arrangement of the Air supply line in the brake carrier allows a constructive simple design of the entire compressed air supply, because the brake carrier in the form of an air feed line without further notice of compressed air lines if it does not is itself designed so that a hollow chamber, the air feed line forms.
- the air feed line is arranged in parallel Air feed line is associated with the first air feed line connected and / or provided with elastic blowpipes is, each a disc brake of a lower one Blow on the coil level.
- the further, parallel air feed line improves the compressed air supply to the disc brake if appropriate dimensioned, constant pressure compressed air source or them enables a complete blowing of another disc brake especially from above.
- the disc brake is designed so that the Air supply line at one end and / or in the area of field surges of the creel is fed.
- the thread 11 shown is one not shown Coil of a creel in the direction of arrow 11 ' withdrawn with a winding machine, for example with a Warping machine or with a slip machine.
- the thread 11 passes through the disc brake 10, which it for winding required thread tension issued.
- the disc brake 10 has an upper plate 14 which is on a lower plate 26 lies on. Both form one with the visible flattenings Plate gap 35 through which the thread 11 in and through the Disc brake 10 is pulled.
- the plates 14,26 are bowl-shaped pressed parts, the outer shell edges parallel to a central axis 41 point up or down.
- the plates also have 14.26 inner recesses formed by inner edges parallel to the outer edges 14 ', 26', so that the plates 14, 26 actually are circular.
- a disc brake 10 is with its plates 14,26 on one arranged horizontally extending brake carrier 12, the F-shaped shown in Figure 1 example Cross section. Above this brake carrier 12 or A bearing plate 36 is provided lying directly on this, which carries 39 eyelets 40 with bends, which on Height of the plate gap 35 are arranged and as a result of the illustrated Opposite arrangement the passage area of the thread 11 set by the thread brake 10.
- the bearing plate 36 carries a plate axis 13 for support the plate 14.26.
- the support is made with a resilient Ring 28, for example a foam ring. Consequently the lower plate 26 can move downwards, if a knot of thread 11 passes through.
- this ring 28 is stiff enough to be required by one Pressure device 20 applied to the upper plate 14 pressure forces to be able to support.
- the compliant ring 28 must in turn be direct or indirect are supported on the plate axis 13.
- the Plate axis 13 assembled with the bearing plate 36, on which Bearing plate of the ring 28 could be supported. That would in a design of the disc brake 10 without a drive Thread cleaning the case.
- the ring 28 is supported however indirectly via a bearing shaft 25 with which the lower one Plate 26 to be driven via the ring 28.
- the bearing shaft 25 has a shaft end 25 'that the brake carrier 12 interspersed.
- the bearing shaft 25 is supported however not directly on the brake carrier 12, but in one formed by the bearing plate 36 bearing recess 24, the is formed by an annular projection 42 of the bearing plate 36.
- This bearing recess 24 is above the brake carrier 12 and radially expanded within the bearing plate 36 so that the Bearing shaft 25, the ring 28 with an outer circumferential groove 25 '' can accommodate that the ring 28 radially spaced from the adjacent Has bearing plate 36 relative to which it rotates.
- a carrier parallel is used to drive the bearing shaft 25 Traversing rod 27, the back and forth vertically to the display plane can be moved. The extent of the movement is measured that the lower plate 26 rotates by more than 360 °. Consequently most thread abrasion parts are certain to be stripped without lumps forming in the area of the plates can. Wear on the pair of plates is also prevented.
- the traversing rod 27 engages with a Rack piece 27 'in the teeth 25' '' of the bearing shaft end 25 '.
- the drive of the bearing shaft 25 acts by means of the ring 28 only on the lower plate 26. So that the upper plate 14 swings back and forth to the same extent, there is a spring 29 which is formed from a piece of wire is. One end of which resiliently clamps in the hollow Bearing shaft 25.
- the inside diameter of the hollow bearing shaft 25 is dimensioned so large that the radial direction on the brake carrier 12 projecting inner plate rim in the bearing shaft 25 can engage.
- the other end of the piece of wire engages in the upper plate 14.
- the upper plate 14 is used to generate a braking force pressed onto the lower plate 26.
- a pressure device 20 is also described in EP 0 529 429 A1, whereupon hereby Reference is made.
- the plate brakes 10 shown in FIGS. 1, 2 are each designed so that they have an air duct 50, with the one or more fiber dust collection points 51 in the area the saucer 26 can be blown.
- a fiber dust collection point 51 is the cavity 55 to watch.
- the air duct 50 is continuous in FIGS thin lines that mark the course of the Illustrate air duct 50 below the saucer 26. The arrows of the thin lines symbolize the muzzle points of the air duct 50.
- the air duct 50 has in the area of the plate axis 13 or in the bearing shaft 25, an annular groove 52, which is opposite the Bearing plate 36 is sealed in a manner not shown.
- the annular groove 52 extends over the circumference of the plate axis 13 evenly distributed axial or vertical outlet openings 53, which is directly on the bottom 54 of the saucer 26 lead to.
- the air flows in from this underside 54 the cavity 55 of the plate axis 13. If for the air flow Connection of the passage cross section between the inner plate edge of the saucer 26 and the upper end 63 the bearing shaft 25 is not large enough, can be slot-like here Connection openings 64 are provided which are not in shown way evenly over the inner circumference of the bearing shaft 25 are distributed. With the help of those exiting here Compressed air can clean both the underside 54 of the plate 26 are blown, as is the cavity 55 of the plate axis 13.
- the dust blown out of the ring 28 enters a space 65 between the bearing shaft 25 and the ring 28 on the one hand and the bearing plate 36 on the other hand. From here on out any dust is blown upwards as shown, whereby there can also be blowing openings 56 which form the annular groove 52 connect to room 65.
- the Air from the air feed line 60 through the connection bore 66 in the ring channel 59 of the bearing plate 36. From there the air through the one or more air slots 57 into the annular space 52 of the plate axis 13.
- the annular space 52 is with one or more vertical outlet openings 53 provided. From the outlet openings 53 air flows against the underside 54 of the saucer 26 and is redirected there and flows into the cavity 55 of the plate axis 13 and on the other hand by the porous ring 28 in space 65.
- the supply air slots 57 are in turn from an annular channel 59 of the bearing plate 36 supplied.
- the supply air slots 57 are evenly distributed around the circumference of the bearing plate 36 and may be connected to blow holes 58 from the ring channel 59 with a short way into the room 65 between the bearing plate 36 and ring 28 blow for effective removal to cause existing fiber dust.
- the ring channel 59 of the bearing plate 36 is through a recess formed, which seals against the brake carrier 12 is and via a bore 66 with an air feed line 60 is in fluid communication.
- the air feed line 60 runs parallel within the brake carrier 12 and is fed in in a manner not shown.
- Another air feed line is parallel to the air feed line 60 61 shown with the air feed line 60 can be connected via a bore 67. It is then possible, both air supply lines 60,61 for compressed air supply of the air duct 50 and with accordingly large blowing volume to work.
- the air feed line 61 can but can also be used to apply a blowpipe 62, which blows onto a disc brake 10 'according to FIG is arranged below the disc brake 10, as shown in FIG. In this case, the air feed lines 60, 61 are as shown not connected.
- the air supply lines 60, 61 are fed in in each case at their ends or at one of their ends. But it is also possible to feed in fields. Then every field of a creel supplied separately, for example what then It is an advantage if the coil creel changes field by field he follows.
- the blowpipes 62 shown can be elastic and consequently hinder working on the Not when winding the bobbin. With field-wise feeding it is understood that the air feed lines 60.61 one Field at a field joint from the air feed lines 60.61 neighboring field must be separated.
- the feed of compressed air for a creel as a whole depends on the respective needs.
- the creel can run continuously can be supplied with compressed air, but it can also be in places and / or be supplied discontinuously with compressed air.
- the choice of the respective compressed air supply is electrical Aids adjustable.
