Definitions

  • the present invention relates to improved apparatus and methods forming spiral hose typically from polyurethane or polyamides such as nylon.
  • Spiral hose typically comprises tightly adjacent spiral loops of hose with the diameter of each of the spiral loops being substantially the same.
  • the hose may be expanded in length by pulling the adjacent spiral loops apart or contracted in length by allowing the spiral loops to flex back their free position of being closely adjacent each other.
  • Current methods and machinery for producing this type of hose involve lengthy, discontinuous and complicated procedures as a result of which such hoses are relatively expensive.
  • the objective of the present invention is to provide both a method and apparatus for producing such spirally wound hose, whether reinforced or not, which simplifies the production of same and reduces its cost of production.
  • the apparatus and method may involve continuous or semi-continuous production from initial extrusion of the hose through to final formation of the spirally wound hose sections.
  • this hose may be first produced as a desired length and subsequently processed in a batch wise process to form the desired length or lengths of spirally wound hose. It will of course be recognised that non- reinforced hose may be similarly processed if desired.
  • the present invention provides apparatus for producing spirally wound hoses including a rotating hose laying means through which the hose passes in a softened condition, said hose laying means having a discharge end which is adapted to rotate about an axis to form spiral loops of said hose adjacent one another while still warm and soft and a former means for holding said spiral loops for a period of time before being released.
  • the former means is adapted to move away from the discharge end of the hose laying means as the spiral loops are formed therein.
  • the apparatus may include an extruder for extruding polymer material in the form of a hose and a rotating calibrator for sizing the hose received from the extruder.
  • a length of previously formed hose may be placed in or passed through a heating means to heat the hose to a desired soft condition before being passed to the hose laying means.
  • a rotating drive means is provided for drawing the hose from a preceding stage and supplying same to the hose laying means.
  • the present invention provides a method of producing spirally wound hose including the steps of :-
  • the holding means is caused to move away from the discharge point of the hose laying means as the spiral loops are formed therein.
  • the hose is initially formed by extruding polymer material through an extrusion die and thereafter the hose thus formed is passed through a rotating calibrator for sizing the hose received from the extrusion die.
  • a length of previously formed hose may be placed in or passed through a heating means to heat the hose to a temperature sufficient to soften the hose to a desired condition.
  • a temperature is in the range of 140 to 180°C.
  • the hose is drawn by a rotating drive means before being delivered to the rotating hose laying means.
  • a rotating drive means for rotating the hose.
  • apparatus for producing longitudinally twisted tubular plastic material including a rotary drive means having first forward drive means to move said tubular plastics material forwardly in a longitudinal direction of the tubular plastics material, and second rotational drive means to impart a twisting motion to said tubular plastics material as said tubular plastics material moves in a forward direction, said second rotational drive means being adjustable to vary pitch of the twist imparted to said tubular plastics material independently of operation of the first forward drive means.
  • the first forward drive means includes a plurality of roller means, each having a circumferential edge engaging said tubular plastics material and configured to at least partially surround an outer surface of said tubular plastics material, said roller means being arranged in at least two groups with the roller means of each said group being located on opposite sides of said tubular plastics material, said roller means being rotationally driven to move said tubular plastics material forwardly in the longitudinal direction of the tubular plastics material, said roller means further being mounted from a common support means rotatable about a longitudinal axis of said tubular plastics material, said second rotational drive means being provided to drive said common support means to impart rotational movement thereto as the tubular plastics material is moved in said longitudinal direction.
  • FIG. 1 is a schematic view of apparatus capable of performing the present invention
  • FIG. 2 is a more detailed view of the rotating haul off mechanism for the extruded hose shown in FIG. 1 ;
  • FIG. 3 is a more detailed view of the rotating calibrator forming part of the apparatus of FIG. 1
  • FIG. 4 is a schematic view similar to FIG. 1 showing an alternative preferred form of apparatus for carrying out this invention
  • FIG. 5 is a section view taken along line N-N of FIG. 1 ;
  • FIG. 6 illustrates features of a potential variation to the embodiment illustrated in FIGS. 1 or 4;
  • FIG. 7 is a section view taken along line N-N of FIG. 6 and
  • FIG. 8 is a section view taken along line NI-NI of FIG. 6.
  • the apparatus generally disclosed in FIG. 1 includes an extruder 10 having an extruder die 11 for extruding polymer materials such as polyurethane or polyamide into a hose form 12.
  • the hose form 12 passes into a rotating calibrator 13 located within a cooling fluid (typically water) 14 held within a stationary vacuum tank 15.
  • the hose form 12 passes through the vacuum tank 15 to be drawn by a haul off arrangement 17 including a series of rollers 16 mounted in a rotating support structure 16 and thereafter delivered to a rotating flyer 18 to be laid in a spiral pattern in the longitudinally extending cavity 19 of circular cross-section formed between two adjacent legs of upper and lower caterpillar endless tracks 20, 21.
  • the thus spirally wound hose 12 is maintained within the cavity 19 for a time sufficient for the hose to set in this formation and be discharged as a complete spirally wound hose section at a discharge end of the caterpillar tracks 20, 21.
  • the flyer 18, the rotatable structure 17 of the haul off rollers 77 and the rotating calibrator all are conveniently driven rotationally from a common drive D.
  • the haul off rollers 77 are themselves driven by a separate variable speed motor.
  • the rotating calibrator 13, as shown in FIG. 1 and FIG. 3, preferably comprises a hollow perforated metal pipe 70 having a first narrow section 22 and a downstream wider section 23.
  • the first section 22 has an internal diameter equal to that of the hose 12 intended to be produced and acts to size the outer diameter of the hose 12.
  • Appropriate seals are provided between end walls 24, 25 of the tank 15 and the calibrator 13 to ensure water does not leak therefrom.
  • the perforations in the calibrator allow the water to contact and cool the hose and the vacuum conditions above the water ensures that the outer diameter of the hose is maintained both circular as well as at the desired dimension.
  • Appropriate bearings 26, 27 within the tank and/or end bearings 71, 72 may be provided for the calibrator 13 to support same during rotation within the tank 15.
  • the calibrator tube 70 may be rotated by gear or pulley means 63 connected to the tube 70 being rotated via drive line means 74 from a drive motor 75 (FIG. 2). It will of course be appreciated that other form of rotary calibrator might be used including those utilising a cooling fluid spray rather than a bath as described above.
  • the arrangement 17 includes a number of rollers 77 in a first aligned group 78 and a second group 79 of rollers 77 with each group being located on opposed sides of the hose 12.
  • the peripheral edge surfaces of the rollers 77 are concavely grooved to conform with at least a part of the external surface of the hose 12 whereby they contact same and, upon rotation, drive the hose in a forward direction longitudinally of the hose itself.
  • the support structure 76 for the rollers 77 is supported via suitable bearings for rotation about the longitudinal axis 28 of the hose.
  • the rotary flyer 18 is similar supported in bearings and appropriate drive line means 80 and 74 are provided from a drive motor 82 so that both are rotated synchronously with one another.
  • Each of the rollers 77 are driven via shafts 83 or 84 carrying suitable worm gears or the like.
  • timing belt drive arrangement may be utilized.
  • the drive shafts 83, 84 may in turn be driven by gearing, pulley drives or the like 85 rotatably mounted in the support structure 76 via the drive line 86 from a separate motor 87, conveniently independent from the drive motor 82.
  • the speed of the two motors 82, 87 may be controlled by a microprocessor 88 or the like to ensure that the rotational motion imparted by the motor 82 corresponds correctly to the forward movement of the hose 12 to ensure the spiral loops of hose are correctly formed as described hereinafter.
  • the rotary flyer 18 conveniently rotates about the central longitudinal axis 28 coincident with the axes of the extruder die 11 , the rotary calibrator 13, the rotary haul off structure 17 and the cavity 19 of the caterpillar tracks 20, 21.
  • the flyer 18 further includes a discharge end 29 radially spaced from the axis 28 such that hose leaving this end travels a circular path with its outer most surface approximating the distance the surface of the cavity 19 is spaced from the axis 28. In this manner the hose may be laid in closely adjacent spiral loops within the cavity 19.
  • the arrangement discussed above essentially produces a spiral hose of any desired length in a semi-continuous fashion. If desired, the length of spiral hose produced may be divided into shorter lengths.
  • Figure 4 illustrates a possible alternative to the apparatus shown in Figure 1 , particularly adapted to form previously manufactured hose into spirally wound hose as may be desired.
  • the hose may be either reinforced or not reinforced.
  • the heating means may be an oven or any other suitable means for heating the preformed hose to a desired softening temperature.
  • One possible embodiment may be to hold the preformed hose on a spool 61 which itself can rotate about its own horizontally arranged axis 62 and further is mounted on a turntable 63 for rotation about a vertical axis 64.
  • the turntable 63 is driven at an appropriate speed from the common drive D that also rotates the rotatable haul off structure 17 and the rotary flyer 18 similar to the arrangement of Figure 1. In this manner twisted softened hose 12 is delivered to the rotary flyer 18 in a similar condition to the hose 12 of Figure 1 and the formation of the spiral loops occurs in exactly the same manner as with Figure 1 and as further described hereinafter.
  • Figure 6 represents a portion of the caterpillar endless tracks 20 and 21 each formed by adjacent block members 30, 31.
  • Each of these block members has a semi-circular surface forming an inner recess 32 which together form an elongate cavity 33 similar to the cavity 19 of Figure 1 or 4.
  • the number of block members 30, 31 or alternatively the length of the cavity 33 formed by co-operating block members 30, 31 defines the length of the hose portion formed by adjacent spiral loops.
  • Each section of block members 30, 31 are interspaced by specially formed block members 40, 41 and 50, 51 as shown in Figure 6.
  • the block member 41 includes a downwardly directed recess or slot 42 having a width equivalent to the diameter of the rotary flyer 18.
  • the block members 50, 51 each include semi-circular recesses 52, 53 with the member 51 further including a downwardly extending slot 54 also having a width equivalent to the diameter of the rotary flyer 18.
  • the depth of the slots 42 and 54 are the same and are the same distance from the axis 28 as is the surface of the recesses 32.
  • the above described arrangement may operate as follows. With the flyer 18 rotating about axis 28, spiral loops are formed in the cavity 33 formed by a section of block members 30, 31 , members 30, 31 , for example, the right hand block members 30, 31 shown in Figure 6. At the same time, the calibrator and the hose haul off structure 17 are rotated as described above. Then, as block members 40, 41 approach the flyer 18, the flyer stops rotating at bottom dead centre so that the hose 12 engages within the slot 42. The speed of movement of the caterpillar tracks 20, 21 is then increased while the flyer 18 is stationary to compensate for the fact that no spiral hose loops are being laid. A desired length of straight hose 12 is then produced until block members 50, 51 come into position with the slot 54 engaging the straight length of hose.
  • the flyer 18 may again commence rotating such that a further spiral loop section is produced and the speed of the caterpillar tracks slow down to allow spiral loops to form.
  • the straight hose sections 12' can be cut or otherwise separated at an intermediate position to form respectively a straight tail and start portion.
  • the short straight sections extend longitudinally but adjacent the circumferential edge of the spiral loops. If it is desired for these straight sections to extend longitudinally but at or adjacent the central axis of the spiral loops, then the central circular apertures 52, 53 may be used to form the straight portion 12'.
