Definitions

  • An output roller has filamentary material pulled off from it under tension so that the material can be applied to the workpiece.
  • One or more supply spools carry a supply of the filamentary material and are rotatable in response to the withdrawal of such material as it is being furnished to the output roller.
  • a braking arrangement including one roller about which the filamentary material passes and is displaceable between a first and a second operative mode in which it respectively permits and prevents the rotation of the supply spools and consequently the withdrawal of the filamentary material from them.
  • a loop-forming arrangement includes another roller about which the material also passes and permanently tends to move from an inoperative position to an operative position in which latter it forms a storage loop from a length of the filamentary material intermediate the output roller and the supply spools.
  • the loop-forming arrangement responds by moving to its operative position when the braking arrangement moves to its first operative mode in which it permits rotation of the supply spools.
  • the braking arrangement is automatically made to move back into its second mode, so that the output roller can now withdraw filamentary material only from the loop until the length of material making up the loop is used up whereupon the loop-forming arrangement returns to its inoperative position.
  • a release arrangement displaces the braking arrangement to the first mode of operation in automatic response to the movement of the loop-forming arrangement toward the inoperative position thereof.
  • a preventing arrangement prevents contact between the rollers irrespective of their relative positions.
  • the present invention relates generally to an apparatus for applying filamentary material to a workpiece, and more particularly to a winding apparatus for jacketing hoses, conduits, cables or the like with filamentary material, for instance wires.
  • Apparatus of this general type uses a winding support that rotates and carries pivot pins which are connected at one end on the winding support and which carry at their opposite free end a braking disc which can be moved towards and away from the winding support and thus into or out of engagement with the spools which are rotatably mounted on the respective pivot pins and from which the filamentary material is being withdrawn.
  • Another object of the invention is to provide such an apparatus wherein the degree of tension that has once been selected, will be varied neither as a result of changes in the package size of a spool from which the filamentary material is being withdrawn, nor as a result of other factors, such as weights or forces that might otherwise cause such an undue influence, for example at rapid rotation of the winding support.
  • one feature of the invention resides, in an apparatus for applying filamentary material to a workpiece, in a combination which comprises output means from which filamentary material is pulled off under tension to be applied to the workpiece.
  • Supply means carries a supply of the filamentary material and is rotatable in response to withdrawal of the material which is being furnished to the output means.
  • Braking means includes a roller about which the material is trained and is displaceable between a first and a second operative mode in which it respectively permits and prevents rotation of the supply means and withdrawal of the filamentary material from the same.
  • Loop-forming means also includes a roller about which the material is trained and permanently tends to move from an inoperative position to an operative position in which it forms a storage loop from a length of the filamentary material intermediate the output means and the supply means.
  • the loop-forming means is responsive with movement to the operative position to a displacement of the braking means into the first mode and it causes displacement of the braking means back into the second mode as a consequence of the formation of the loop.
  • the output means can withdraw filamentary material only from the loop, not from the supply means directly, and this withdrawal continues until the length of filamentary material making up the loop is used up, whereupon the loopforming means displaces the braking means into its first mode of operation in automatic response to movement of the loop-forming means toward the inoperative position.
  • Preventing means prevents contact between the rollers irrespective of their relative positions.
  • FIG. 1 is a partially sectioned somewhat diagrammatic side view, illustrating an apparatus embodying the invention
  • FIG. 2 is a fragmentary perspective view, illustrating a detail of the apparatus in FIG. 1;
  • FIG. 3 is a vertical section through FIG. 2, partly in elevation, illustrating details of that Figure
  • FIG. 4 is a diagrammatic side-elevation illustrating one operative position of the part of the apparatus that is shown in FIG. 2;
  • FIG. 5 is similar to FIG. 4, illustrating another operative position of the apparatus
  • FIG. 6 is a fragmentary section, taken on line VIVI of FIG. 3;
  • FIG. 7 is a rear view analogous to FIGS. 4 and 5, that is showing the apparatus as it would appear when looked at from the reverse side of FIGS. 4 and 5.
  • FIG. 1 shows in toto and designates with reference numeral 10 an apparatus for applying filamentary material to a workpiece, here illustrated as a hose or conduit 15 about which a jacket of filamentary material, here in for most steel wires 23, is to be applied.
  • a portion of the jacketed hose 15 is visible at the left-hand side of FIG. 1 and designated in diagrammatic illustration with reference numeral 25.
  • the direction of advance- 3 ment of the workpiece, that is the hose 15, is identified by the arrow 16.
  • the apparatus has a frame or support 12 on which a rotary support or winding frame 11 is mounted which is turnable in bearings 13.
  • the winding frame 11 is rotatable in a vertical plane and formed with the illustrated central passage extending along its axis of rotation and through which the workpiece 15 passes.
  • Filament guiding arrangements 14 are provided which are well known in the art and require no detailed discussion; they serve to guide the filaments onto the workpiece 15.
  • a motive means must be provided, for instance a non-illustrated pulloff, which advances the workpiece, that is the hose 15, in the direction of the arrow 16.
  • a gear 17 is fixedly connected with the winding frame 11 which is of essentially disc-shaped configuration, so that the winding frame 11 is driven from its gear 17 which in turn is rotated by engagement with a gear transmission 18 (not shown) located in the gear box 18 and which receives its input from the drive shaft 19 which may be driven by a motor.
  • a gear transmission 18 not shown located in the gear box 18 and which receives its input from the drive shaft 19 which may be driven by a motor.
  • Appropriate couplings may also be provided.
  • the winding frame 11 is formed at its side facing towards the thread guide arrangements 14 with a plurality of supply units 20 which are arranged on circles that are concentric with the axis of rotation of the winding frame 11 and which carry spools provided with supplies of filamentary material.
  • each of the units 20 has a carrier 21 and may have one, but usually a plurality of the spools 22 each of which carries a supply of thefilamentary material 23, which here will be assumed to be in form of steel wires but could of course be a different kind of material.
  • a thread tensioning arrangement 24 is associated with each of the units 20 and the several filaments 23 derived from the various spools 22 of the respective unit 20 pass jointly through the thread tensioning arrangement 24 before being supplied to the thread guiding devices 14 shown in FIG. 1, from where they are supplied at the desired angle of inclination onto the surface of the hose 15 so as to be applied to the latter as the winding frame 11 rotates about and with reference to the hose 15, to obtain the jacketed hose diagrammatically illustrated at 25 in FIG. 1.
  • the longitudinal axis of the pin 26 extends at right angles to the plane of the winding frame 11.
  • the invention is embodied in an apparatus for applying filamentary material to a hose or other workpiece not by winding, but by braiding, the lower end portion 27 of the pin 26 will be guided in a track of the braiding frame that would replace the winding frame 11.
  • the axis of the pins of the several units 20 are horizontally oriented, that is they extend in parallelism with the axis of rotation of the winding frame 11.
  • friction pads 28 the purpose of which is to provide sufficient friction to retard completely free rotation of the spools 22 with reference to one another and to the winding frame 11.
  • Axially adjacent ones of the spools 22 have the filamentary material 23 wound about them in mutually opposite directions. In other words, in FIGS.
  • the filamentary material 23 is wound about the upper and lowermost spool 22 in clockwise direction whereas it is wound about the intermediate spool in counterclockwise direction.
  • the advantage of this is that when filamentary material is withdrawn from any one of the spools 22, the axially adjacent spool or spools cannot be taken along by the rotary movement which the spool performs from which the filamentary material is being withdrawn, but are instead slightly biassed in the opposite rotational direction so as to tension the filamentary material thereon. This is particularly important in cases where the amount of filamentary material on different spools differs.
  • the filaments 23 withdrawn from the respective spools 22 of a unit 20 are guided over rollers 29 located at the level of the respective spool, and are then supplied to a collecting roller 43 of the thread tensioning arrangement 24, from whereon the several (here three) filaments 23 continue to travel in unison.
  • a braking member of disc 30 is located above the upper end of the spools 22 in the respective unit 20 and is provided with a friction pad or covering 33. It is mounted axially movable at the upper free end 31 of the pin 26. As indicated by the force vector P in FIG. 3, the brake disc 30 is moved in axial direction of the pin 26 to be pressed against the uppermost spool 22 in a manner and by means to be described subsequently. The extent of axial movement is very small, and need vary only within the range of wear of the pad 33 and the compressibility thereof.
  • a control arm 37 is provided the elongation of which is indicated by the broken line 38 in FIG. 3 and will be seen to extend parallel to the plane of the winding frame 11.
  • the brake disc 30 is connected rotatably at 36 with the arm 37, which latter is pivoted at two pivots 39 (note in FIG. 2 that the arm 37 in this embodiment is composed of two transversely spaced parts which are connected by a connector 41) to a support 40 which is fixed with reference to the pin 26 and in the illustrated embodiment is also carried by the winding frame 11.
  • the support 40 in this embodiment also carries thhe rollers 29 which have been mentioned earlier.
  • the braking disc 22 be made removable. This can be done by pivoting the control arm 37 in the direction of the arrow 83 (see FIG. 4) about the pivot axis 39, thus moving the control arm 37 which extends radially with respect to the winding frame l1upwardly in FIG. 3. The pull exerted thereby causes an automatic disengagement of the legs of the spring 36 from the pin 26, inasmuch as the legs flex outwardly and snap out of the circumferential groove 32. Of course, when the movement is subsequently reversed, these legs will snap back into the groove. When the control arm 37 has been thus pivoted upwardly, the spools 22 can readily be withdrawn from the pin 26 for replacement with full ones.
  • the control arm 37 is formed at its free end (the left end in FIG. 2) with a roller 47 which in the operative condition of the unit is located in the region of the thread tensioning device 24, as shown in FIG. 2.
  • the filaments which move around the roller 43 of the thread tensioning device 24, continue to an input roller 44 which is mounted for rotation in an inclined position. They thus move into that radial plane of the winding frame 11 in which the sensing roller 42 on the arm 37 is also located.
  • the filaments 23 then pass around the sensing roller 42 and further around a tensioning roller 46 which is turnably mounted on an arm 45 that can be pivoted in a manner still to be described. From the roller 46 the filaments travel via an output roller 47 to the final output roller 48 from where they are supplied to the filament guiding arrangements 14.
  • FIG. 6 shows most clearly that the roller 44 is formed with one or more circumferential grooves, as are the rollers 46 and 47. These grooves are located essentially in a common plane extending radially of the winding frame 11. Because of the manner in which the section of FIG. 6 is taken, the roller 44 would be invisible and it has therefore been shown in broken lines.
  • FIG. 6 Also shown in FIG. 6 is the fact that the pivot arm 45 carrying the tension roller 46 is connected with a sleeve 49 which is journaled at its opposite axial ends in bearings 50, 51 and thus makes possible the pivoting of the arm 45.
  • the output roller 47 is ring-shaped and is journaled on the sleeve 49 by means of roller bearings 52.
  • the sleeve 49 itself is accommodated in a housing of the device 24, which housing is composed of two parts 53 and 54 and is connected to the winding frame 11 in the illustrated embodiment.
  • a shaft 55 is accommodated in the housing 53, 54 and is surrounded in its middle portion by a torsion spring-56 which is accommodated over a substantial portion of its length in the sleeve 49.
  • a toothed blocking wheel 57 has a hub 59 which is of polygonal interior cross-section and into which one end portion of the shaft 55 extends matingly so that the two are connected for joint rotation.
  • the wheel 57 is located at the exterior of the housing portion 54 and is formed with a sleeve portion 58 which extends into a bore of the housing portion 54.
  • Located on the inner end of the sleeve portion 58 is the bearing 51 for the sleeve 49, and one end of the torsion spring 56 is fixedly connected in the region of the shoulder 60 with the shaft 55.
  • the other end of the torsion spring 56 is connected with a ring 64 which surrounds the shaft 55 and is slidable axially of the same.
  • the ring 64 has a radial guide pin 65 which extends into an elongated slot 66 formed in the sleeve 59 and extending axially of the latter. That end of the shaft 55 which is located in the region of the ring 64 is formed with a thread. A nut 61 is threaded onto this thread and serves to secure a cover 62 on the shaft 55 so that the cover turns with the shaft. The cover closes a bore in the housing portion 53 and is formed with a sleeve portion 63 on which the bearing 50 of the sleeve 49 is secured.
  • FIG. 7 Details of the wheel 57 are visible in the rear view of the arrangement that is shown in FIG. 7. It will be seen that a double-tooth pawl 67 is pivotably mounted adjacent the wheel 57 on the housing portion 54, by means of a screw 68. A spring 69 is connected with the pawl 67 and normally maintains one tooth of the pawl in engagement with the teeth of the wheel 57. It is clear, therefore, that the wheel 57 and the pawl 67 together form an escapement.
  • the pawl 67 is provided with a handle 70 by means of which an operator can manually pivot the pawl 67 about the pivot axis defined by the screw 68, counter to the force of the spring 69, to thereby move one tooth of the pawl 67 out of engagement with the teeth of the wheel 57 to permit the latter to turn in the direction of the arrow 71 and under the influence of the torsion spring 56, by the length of half a tooth in reverse direction. This is possible because at this time the other tooth of the pawl 67 will already engage again with the teeth of the wheel 57.
  • the handle is disengaged, the pawl 67 of course is urged by the spring 69 to the position shown in FIG.
  • the end portion of the torsion spring which is connected with the shaft 55 can be considered as the fixed end portion, whereas the other end portion connected with the ring 64 can be considered as the movable end portion.
  • FIGS. 4 and show the arrangement of FIGS. 2 and 3 in somewhat diagrammatic form.
  • the various rollers have been for the most part shown by broken lines, as if they were transparent, in order to be able to more clearly show the configuration assumed by the filaments 23.
  • FIG. 5 shows the arm 45 in a position representing the maximum displacement which can occur for the arm 55 under the urging of the torsion spring.
  • the filamentary material which is supplied to the thread guiding devices 14 from the device 24 will have a predetermined desired tension. Since the filamentary material is guided around the roller 46, the latter will always constitute the apex 74 of the loop formed from the filament portion or length 23. That part of the loop which is identified with reference numeral 75 is always straight until it comes in contact with the roller 47.
  • the other part of the loop is identified with reference numerals 76, 76 and hence composed of two sections.
  • These two sections 76, 76' will include with one another an angle that may vary between zero as shown in FIG. 8 and FIG. 4 and the maximum angle shown in FIG. 5, depending upon the position of the arm 45 and the roller 46.
  • the section 76 will to all intents and purposes always be located on the line 78 that has been shown for the purposes of explanation in FIGS. 4 and 5, whereas the section 76 will be angled to a greater or lesser degree as explained above.
  • the angle a which is included between the section 76, 76' will be the more pronounced, 76'farther the roller 46 on the arm 45 pivots away from the roller 44 (in clockwise direction in FIGS. 4 and 5). Conversely, the angle a will decrease as the arm 45 with the roller 46 moves in the opposite direction from the position of FIG. 5 back to or towards the position of FIG. 4, counter to the urging of the torsion spring 56.
  • the force acting upon the control arm 37 can be subdivided into two components, namely one component P which acts longitudinally of the control arm 37 in the direction of the line 38 and is absorbed at the pivot axis 39 and thus does not influence the movements of the control arm 37.
  • the second force component P produces upon the control arm 37 a turning movement which urges the control arm 37 in a direction in which it presses the brake disc 30 against the spools 22 with a force P which has been multiplied by the lever action of the arm 37.
  • the force P is so large with reference to the existing filament tension, that the filament tension is not sufficient to cause the spools 22 to rotate, so that the latter are precluded from such rotation and from paying-out of filamentary material.
  • the filaments 23 continue to be subjected to the tension imparted to them via the torsion spring 46, and in fact this tension has slightly increased with respect to the previous position of FIG. 5, because the torsion spring 56 has been tensioned somewhat more during the movement of the arm 45 to the position in FIG. 4.
  • This increase in tension is however minor and to all intents and purposes the previously elected level of tension is maintained unchanged.
  • This filament tension is sufficient to cause turning of the spools 22 in a sense paying out filamentary material from the latter.
  • the force acting via the spring 56 and the filamentary material upon the spools 22 will be sufficient to cause turning of the latter at the latest when the arm 45 has reached the position of FIG.
  • the length of the filament portion 23' forming the loop in FIG. can be determined, and this in turn determines the extent to which the arm 45 can pivot (in FIG. 5) in clockwise direction.
  • Another source of difficulty is the fact that the overall diameter of the respective spool 22, that is of the package of filamentary material wound onto the same, varies in dependence upon the amount of filamentary material that has already been withdrawn, thus varying the torque acting upon the spool when material is being withdrawn from the same.
  • an abutment is provided at the free end of the control arm 37, which serves to aid in lifting of the control arm.
  • This abutment can be variously constructed or configurated, but here uses a bolt 79 which is eccentrically mounted on the free end of the control arm 37 by means of a nut 40 and which carries the sensing roller 42.
  • the eccentricity of the bolt 79 makes possible a variation of the engagement of the bolt 79 with a cooperating abutment 81 which is formed on the arm 45 in the manner of a nose as shown in FIG. 3.
  • the bolt 79 extends into the path of movement of the abutment 81 as the arm 45 pivots, and in the illustrated embodiment the arrangement is so selected that the abutment 81 of the arm 45 begins to lift the control arm 37 via the abutment 39 thereof when the positon shown in FIG. 4 has been reached by the arm 45.
  • the abutments on the arm 37 and the arm 45 it is possible to obtain an earlier engagement of the two abutments, which means that under all circumstances the arm 37 will reliably lift the braking disc 40 off the associated spool 22 at the desired time, thus permitting rotation of the spools 22 in order to free another length of filamentary material.
  • the abutments constituted by the portions 79 and 81 are so arranged that when the arm 37 is lifted by their cooperation, the sensing roller 42 does not cause an undesired increase of the angle a included between the two sections 76, 76. Instead, the abutments serve to assure that the roller 46 will move rapidly once they cooperate with one another, and that thus the angle a cannot increase and may even further decrease, which reliably avoids excess tension in the filamentary material. In the exemplary embodiment this means that the arrangement of the rollers 44, 42 and 46 in a straight line will remain unchanged, even as the arm 37 continues to move upwardly as a result of the cooperation of the components 79 and 81. Fi-
  • the abutments in such a manner that when they do contact one another, they can do so only when the filament sections 76, 76' include with one another an angle of substantially i.e. when they have the orientation shown in FIG. 4.
  • the roller 42 is essentially free of any forces that might be transmitted to it by the filamentary material 23, so that the abutments need not counteract such forces when the arm 37 is displaced in a sense causing braking of the spools 22.
  • a combination comprising output means from which filamentary material is pulled off under tension to be applied to the workpiece; supply means carrying a supply of the filamentary material and being rotatable in response to withdrawal of such material which is being furnished to said output means; braking means displaceable between a first and a second operative mode in which it respectively permits and prevents rotation of said supply means and withdrawal of the filamentary material from the same, said braking means including a first roller about which said filamentary material is trained; loop-forming means including a second roller about which said filamentzry material is also trained and permanently tending to move with said second roller from an inoperative position to an operative position in which it forms a storage loop from a length of said filamentary material intermediate said output means and said supply means, said loop-forming means being responsive with movement to said operative position to a displacement of said braking means into said first mode and causing displacement of said braking means back into said second mode as a consequence of the formation of the loop, whereby said output means can
