Definitions

  • the present invention relates to a coiler for depositing elongated flexible material such as bare or coated wires, or strands of wires into a barrel-like container; more particularly, the invention relates to a coiler which deposits such material in a rosetta-shaped configuration, layer upon layer, in a suitable container.
  • French Patent No. 1,237,747 corresponding approximately to U. S. Pat. No. 3,093,339 discloses a coiler wherein wire is wound upon a drum by meansof a winding or coiling head.
  • the drum has configuration of a horizontally disposed disc, and the coiling head deposits loop above loop onto the periphery of that drum or disc. The loops are progressively pushed down so that the respective lowest loop drops into a barrel.
  • German Patent No. 1,031,252 it is suggested to provide a deflecting member which is, so to speak, in the way of a dropping loop and which rotates slowly (slower than the coiling head).
  • the respective dropping loop obtains a preferred direction of extension, as far as loop configuration is concerned, i.e., it is eliptically distorted.
  • the rotation of the deflecting member that the loops which-drop progressively downward undergo an angular precession or phase shift as to eliptical orientation and that in turn results in a rosettashaped configuration.
  • U. S. Pat. No. 2,991956 is likewise of interest in this respect.
  • the number of revolutions of the coiling head determines the number of loops per unit time that are deposited in the barrel; the considerably lower speed of rotation of the deflecting member determines the angular precession, he the phase shift among the rosetta or elipse peaks, around the axis.
  • the coilers operate properly as long as the bare or coated wires are free from torsional strain.
  • Torsion is particularly prevelant if the elongated material to be coiled is actually stranded or twisted or otherwise intertwined. Even if stranded wires are jacketed, for example, by a shield or the like, they stillare not free from torsional strain.
  • the loops upon dropping, do not retain the particular loop configuration 9Particularly as far as elipse orientation is concerned). They may be twisted in the process which may cause kinking or other damaging to the strand.
  • a pair of pulleys is provided to serve as a slowly revolving deflecting member, whereby at least one pulley is driven so that its circumferential speed is larger than the propagation or pay-in speed of the elongated material as it enters the coiler.
  • the pair of pulleys is guided along a track at a revolving speed equal to the revolving speed of the coiling head, but the track has excentric position to the axis of the drum and revolves by itself about the axis; preferably that track is a circular one with an off-center position.
  • the carriage and holder for the pulleys may be driven by separate drive; however, it is simpler and equally suitable to couple the. carriage and holder to the revolving coiling head. This is particularly carried out by having the holder for the pair of pulleys. linked pivotably to the arm that carries the coiling head to offset the excentricity of the pulley or the holder. This way the pair of pulleys will indeed follow the circular track as it is excentrically positioned in relation to the axis of the drum, and synchronization with the coupling process is insured.
  • FIG. 1 illustrates a side elevation of a coiler constructed in accordance with the preferred embodiment of the present invention.
  • FIG. 2 shows somewhat schematically a resulting loop pattern in a barrel in which the coiler deposit the several loops of elongated material.
  • FIG. 1 a stand or frame '1 journalling a hollow shaft 2.
  • the shaft 2 is driven by means of a drive that is not illustrated but engages a gear 3 on the shaft.
  • Hollow shaft 2 has a slot 4, and a first guide pulley 5 extends partially into that slot.
  • Pulley 5 has a horizontally oriented axis, and the position of the guide pulley is elected so that the axis of shaft 2 is tangent to the periphery of pulley 5.
  • Elongated, flexible material, such as bare or coated wire 6 runs into the hollow shaft 2 as is, for example, shown in US. Pat. No.
  • the revolving coiler proper includes a circumferential housing that is positively connected to shaft 2 and rotates therewith.
  • housing 10 supports the obliquely positioned pulley 27, i.e. that pulley is journalled for free rotation, on an arm 101 that extends from housing 10.
  • housing 10 includes bearings for a shaft 11 that is disposed eccentrically to the axis of hollow shaft 2.
  • Shaft 11 carries a pinion 9 that meshes in statinary pinion 8, pinion 8 being mounted on frame 1 and being stationary accordingly. Therefore, upon rotation of housing 10, shaft 11 revolves about the common axis of housing 10 and shaft 2. Since pinion 9 meshes stationary pinion 8, the shaft 11 (l) revolves around the axis of shaft 2 and (2) rotates about its own axis.
  • a drum 7 is provided to receive the loops of elongated material as the coiling pulley 27 revolves about the axis of shaft 2.
  • the drum 7 is provided as a hollow element and is rotatably positioned on shaft 2.
  • gearing of the type disclosed in the aboveidentified corresponding U. S. and French patents, that gearing cooperates with the pair of pinions 8 and 9, and shaft 11 actually causes the drum 7 to remain dynamically stationary.
  • a wobble ring 12 is provided which can likewise be constructed as is taught in the above-identified three patents.
  • the wobble ring rotates about the system axis and causes loops 14 as they are wound upon the periphery of the drum to be pushed down, so that free winding space is always available on the periphery of drum 7 for receiving another loop of stranded material as it runs off pulley 27.
  • hollow drum 7 includes a planetary gear for driving a drum 13 which is coaxial to the several elements mentioned above (axis of shaft 2) and which is relatively suspended from drum 7.
  • Drum 13 serves as a spacer for the dropping loops.
  • the state of the art includes also a deflecting member that reaches into the path of the dropping loops, such as disclosed, for example, in the German Patent No. l,03 l ,252. (See also co-pending application No. 155,804).
  • the particular construction of the deflection member, as disclosed in this specification, is the novel aspect of the invention.
  • a dropping loop does not fall freely, but the string of material is guided by a pair of pulleys 15 and 16.
  • a spring 17 urges pulley 15 towards pulley 16; a holder 21 is provided and having a post 152, traversing a bore in a mount 151 and carrying spring 17.
  • the mount 151 is suspended from the post by the spring 17, which urges the mount in down direction.
  • Pulley 15 is journalled on an arm that extends from mount 151.
  • a post 162 extends from holder 21 and traverses a bore in a mount 161.
  • a spring 18 is interposed to urge mount 161 in up direction.
  • the pulley 16 is journalled on the mount.
  • a traction roller is coupled to pulley 16 and serves as drive thereof.
  • the traction roller 160 runs on a surface of a disc 19 that is mounted on drum 13.
  • the two pulleys 15 and 16 have grooved periphery to positively engage the elongated, flexible material 6 as it passes through.
  • At least one of the two pulleys l5 and 16 is driven, namely pulley 16.
  • the peripheral speed imparted upon pulley 16 by traction roller 160 is larger than the speed of the material that passes the duct established by the grooves on pulleys 15 and 16.
  • This excess speed of the pulley causes exertion of a pulling force upon the elongated material as it runs off drum 7.
  • engagement of the material by faster moving pulley or pulleys establishes an exact definition of the point from which the material is permitted to drop freely, and that in turn suppresses the effect of internal torsion in the elongated, flexible material. As a consequence, the material drops freely into the barrel or other suitable container 100.
  • cylindrical body 13 is drivingly geared to shaft 2 and drum 7 so that it is provided with a very low speed, i.e., it revolves at a very low speed.
  • Disc member 19, as carried by drum 13 is provided with a circular groove 20.
  • the circular groove 20 is disposed eccentric to the common axis of the system, i.e. the groove 20 extends eccentric to shaft 2.
  • Holder 21 for the pair of pulleys 15 and 16 is provided with a roll 22 that engages the top of disc 19 and runs thereon.
  • Holder 21 in addition is provided with a carriage-like construction 23 that guides the holder and the pair of pulleys along the circular track 20.
  • a bolt or pin 24 extends from an arm 241 which in turn extends from housing 10.
  • a lever extends horizontally from the lower end of pin 24 and is freely pivotable on the pin.
  • a guide post 26 extends from mount 151 and is received by an aperture in the end of lever 25.
  • auxiliary pulleys may urge the loops 14 onto the periphery of drum 7.
  • pulleys may be provided which support and guide the'axial advance of the several loops in down direction along the periphery of drum 7.
  • Still additional pulleys may be arranged in pairs and positioned to engage the material along the path from the drum to the particular pair of pulleys l5 and 16 so as to support the material portion from its dropping off the drum, up to the point of engagement with the particular pair of torsioning pulleys 15 and 16.
  • pulley 16 is driven through frictional engagement of roller 160 with disc 19. That disc rotates quite slowly as compared with the revolving speed of coiler and deflection assembly (15, 16, 21, etc.).
  • the diameter of roller 160 determines the number of revolutions of the pulley, and that in turn determines its peripheral speed to follow the rule outlined above.
  • the number of loops deposited into the container l00per unit time is determined basically by the revolving speed of coiler and pulley pair 15-16.
  • the angular precesion of the rosettas as deposited in container 18 is determined by the speed reduction imparted upon cylinder 13 which determines the slow rotational speed of disc 19 and that in turn determines the speed with which the eccentrical track 20 revolves about the axis of shaft 2.
  • L'Apparatus for depositing elongated, flexible material in a container and in a rosetta-shaped pattern therein, the material having a particular pay-in speed
  • the apparatus including a drum having an axis and a coiling head revolving about the axis for sequentially winding loops of the material onto the drum, additionally there being means for pushing the loops axially down for the respective lowest loop to drop into the container, the improvement comprising:
  • first means including a carrier for the pair of pulleys for revolving the pair of pulleys about the drum on the axis thereof;
  • third means for providingand defining an closed loop guiding track for the carrier the carrier having means engaging the track for guiding the disposition of the pair of pulleys in accordance with the track, the track having eccentric disposition in relation to said axis;
  • the third means including a disc that includes said track and revolves about the axis of the drum, the second means including friction means driven by the disc for driving one of the pulleys of the pair.
  • the first means including a pivotal link between the carrier and the coiling head to compensate the eccenticity of the path of the pair of pulleys by operation of the third means.
  • the third means being a disc, eccentricity positioned to the axis of rotation of the revolving coiling head, the disc having an annular groove, the carrier for the pair of pulleys including a carriage that runs in said groove.
