Abstract

A portable rotary tubing straightener apparatus comprises a mobile console with spool mounting assembly. A motor is supported on the console and drives a shaft which mounts a drive roller. An adjustable tensioner assembly has a tension roller positionable opposite the drive roller. The drive and tension rollers are engageable at opposed locations of a continuous tubing. A rotary straightener assembly is disposed on the console. A motor carried by the console is activatable to rotate the rotary straightener assembly. A spool with metal tubing is mounted to the spool mounting assembly and passes tubing through the rotary assembly and between the rollers. Upon activating the motors, the tubing unwinds from the spool and exits in a continuous straightened condition from the drive and tension rollers. A rotary handle is employed for adjusting the tension in the tension roller.

  • DETAILED DESCRIPTION
  • [0028]
    With reference to the drawings wherein like numerals represent like parts throughout the several figures, a portable rotary tubing straightener apparatus is generally designated by the numeral 10. The straightener apparatus is adapted to receive and mount a spool 12 of tubing 14 and to feed the tubing in the feed direction indicated to automatically straighten the tubing for usage. The tubing 14 typically has a continuous long-length configuration of uniform diameter and is manufactured from various metal and steel alloys. The tubing 14 has numerous usages, such as high pressure fuel lines and hydraulic controls. The tubing 14 is typically wound onto spools for storage and transport.
  • [0029]
    The portable straightener apparatus 10 comprises a mobile console 20 having a cabinet form with a heavy duty base 21 supported by omni-directional caster wheels 22. The caster wheels 22 have a manually settable brake 23 for immobilizing the wheels. In the illustrated embodiment, there are six caster wheels. The console 20 has side panels 24, 25 and 26, a front panel 28 and a rear panel 29. Panel 25 is perforated to provide ventilation. Representative dimensions in inches for one embodiment are indicated in FIGS. 3-5 and 9.
  • [0030]
    A spool support stand unwinder assembly 40 is mounted at the rear of the console. The unwinder assembly 40 functions to facilitate the rotation of spool 12 to unwind the tubing 14. The spool support stand assembly includes a laterally projecting axle 42 for receiving the spool and a retainer cap 44 for locking the received spool 12 to the axle 42.
  • [0031]
    The console 20 includes an upper platform 30 which mounts and receives a safety cover assembly 50. The cover assembly 50 encloses a rotatable elongated rotary straightener assembly 60. The rotation of the rotary assembly 60 acts to progressively alleviate coiling in the tubing. The safety cover assembly 50 includes a lower rear aperture 51 and a frontal aperture 53 through which the tubing to be straightened is passed. The safety cover assembly 50 includes an open box-like enclosure with a pair of handles 52 for lifting same from the platform for removal when desired.
  • [0032]
    With reference to FIG. 11, the rotary straightener assembly 60 comprises an elongated arbor 130 which includes access openings 132, 134 and 136. Pegs 142, 144 and 146 are adjusted essentially radially relative to the arbor and are respectively secured by three nuts 148. The pegs 142, 144 and 146 have a generally flat base and are inverted and inserted into the respective openings 132, 134 and 136 and secured by the nuts 148. The pegs are specifically designed for a given tubing size and progressively elastically deform the tubing to make it straight. A tool 150 applies torque to adjust the nuts 148 which are threaded to the arbor.
  • [0033]
    Two substantially identical, spaced upright tube guides 54 and 56 are mounted to the platform 30 forwardly of the cover assembly 50. The guides 54 and 56 have eyes 57 and 59, respectively, for slidably receiving the tubing 14. The guides 54, 56 and eyes 55, 57 align with the apertures 53. A third guide 58 with an eye 59 is mounted rearwardly of the cover assembly 50 to guide the tubing to the rotary straightener assembly 60.
  • [0034]
    With additional reference to FIG. 3B, a projecting latch 64 is secured by a side lock mechanism 66 for securely maintaining the safety cover assembly in a fixed locked position to the top of the platform 30. A safety interlock switch 68 is mounted to a sensor mount 69 to ensure that the safety cover 50 is locked in position while the apparatus is operating.
  • [0035]
    The guides 56 and 58 respectively support the aligned eyes 57 and 59 which slidably receive and guide the tubing for passage to the straightener drive subassembly 80 (best illustrated in FIG. 2). The straightener sub-assembly 80 is mounted to the platform 30 at a forward location.
  • [0036]
    With reference to FIG. 3, the console 20 has an interior support shelf 32 which mounts a motor 70. The motor 70 is preferably a 10 horsepower 3 phase 1200 RPM induction motor which drives a timing belt 72. The timing belt 72 ultimately rotatably drives the rotary assembly 60. A control module 34 for the motor is mounted to the side of the console. The opposing side of the console includes a vent 36 and a ventilator fan 38 for the motor 70.
  • [0037]
    With reference to FIG. 2, the straightener drive subassembly 80 comprises a pair of supports 82 which mount a 3 horsepower, 3 phase 1800 RPM induction motor 90. The motor drives a drive wheel shaft 92 which mounts a heavy duty drive wheel 94. A mounting plate 96 supports an adjustable tensioner assembly 100. The tensioner assembly 100 employs a pivotal tension arm 102 which in turn mounts a heavy duty idler roller 104. The drive roller 94 and idler roller 104 are positioned in opposed relationship. The tubing 14 is captured between the rollers 94 and 104 and propelled linearly outwardly therefrom.
  • [0038]
    A screw shaft 108 having a rotary handle 110 is variably positionable to regulate the tension applied by the idler roller 104 against the tubing. The actuation and operation of the motor 90 causes the rollers to engage opposite sides of the tubing 14 and to progressively payout the tubing 14 in a straight linear fashion as tubing is unwound from the spool.
  • [0039]
    A module 34 houses a PLC, breakers, a transformer, a power supply and a contactor (not illustrated).
  • [0040]
    With reference to FIG. 10, the console has a control panel 120. The control panel includes a rotary dial 122 which via a potentiometer regulates the speed of motor 70 and a second rotary dial 124 which via a potentiometer regulates the speed of motor 90. The motors are turned on and off by a switch 126. An emergency stop button 128 is also supplied to stop the motors in an emergency situation. Upon turning on the on/off switch 126, a ventilation fan 38 is also activated. The fan is activated to control the temperature within the console in the vicinity of the motor 70.
  • [0041]
    The speeds of the motors 70 and 90 are synchronized so that the straightening at the straightener assembly 60 and the drive sub-assembly 80 and the unwinding of the spool is coordinated. The tension on the tubing 14 between the rollers 94 and 104 is adjusted by the handle 110 to provide the proper opposed drive engagement.
  • [0042]
    While a preferred embodiment has been described, the foregoing description should not be deemed a limitation of the invention. Accordingly, various adaptations, modifications and alternatives may be provided without departing from the spirit and the scope of the present invention.
