Definitions

  • a guard encircles the lower portion of the capstan and the coil of discharged strand, and preferably rotates with the receiving tray and capstan. After the desired amount of strand has been drawn and deposited on the tray, the receiving tray is lowered and the coil of drawn strand is removed.
  • This invention relates .to a continuous strand drawing apparatus and more particularly to an apparatus in which rela tively stiff strands such as long lengths of metal tubing, rod or wire are drawn through a die by a capstan large enough to prevent damage to the product as it is bent around the capstan, after which the strand is discharged from the capstan onto a receiving tray.
  • One type of widely used prior apparatus comprises a capstan that is mounted from one end for rotation about a vertical axis and has its other and lower end free; As the capstan rotates, the strand passes from a suitable source such as a payoff coil or reel through a drawing die to a location on the capstan near its upper supported end, on which the strand is wound for several turns for traction; the turns of strand move axially of the capstan and discharge over its free end until all of the strand has passed over the capstan. Since the capstan usually rotates at high speed, means must be provided to catch the turns of drawn strand that discharge from the free end of the capstan, collect them in a coil, and permit removal of the coil.
  • One such commonly used means comprises an annular basket positioned below the capstan, which basket is rotated at approximately the capstan speed. After the basket is filled with a coil of drawn strand, it is then moved laterally to the payoff position of the apparatus to locate the coil for subsequent redrawing passes.
  • This-type of apparatus has disadvantages because a large number of these baskets inust be used in the drawing process at any given time, with resulting considerable investment in baskets, handling equipment, and considerable plant space.
  • Another means that has been used to collect drawn strands is a receiving tray, having a circumferential wall, that performs the same general function as the basket mentioned above, ex-
  • Apparatus embodying the invention preferably comprises stationary supporting means; a drum mounted on the supporting means so the drum is rotatable about a generally upright axis and has a lower free end, the drum having a periphery on which turns of strand are wound, the drum being adapted to discharge turns of strand from its free end; and means for collecting the discharged turns of strand in the form of a coil comprising a strand-collecting member having a strand-collecting upper surface extending generally radially of such axis of rotation, movable supporting means for raising the collect ing member to an upper position where its upper surface is in proximity to the free end of the drum and to lower it to a position in which a coil on the upper surface of the collecting member will clear the free end of said drum, the collecting member being rotatable on the movable supporting means essentially about theaxis of rotation of the drum at substantially the same speed as the drum when the collecting member is in its upper position.
  • guard means surrounding and radially spaced from the drum, the guard means extending upwardly from the collecting member when it is in its upper position and substantially overlapping the free-end portion of the drum, the guard means being rotatable essentially about the axis of the drum at a rotational speed essentially the same as that of the drum, so that turns of strand can discharge from the drum onto the collecting member within the guard means and form a coil of strand on the collecting member.
  • An object of the invention is the provision of apparatus for receiving strand turns discharged over the end of a drawing capstan and readily, safely and rapidly collecting them in a coil which may be readily and rapidly removed without damage to the strand or equipment and with safety to employees,
  • FIG. 1 is a side elevation of apparatus embodying the invention for drawing a strand and collecting the drawn strand in the form of a coil, parts of the apparatus being shown in section for the purpose of clearness, the receiving tray being shown in full lines in its elevated position where it can receive the coil and inbroken lines in its lower position from which the coil can be removed, and means for pushing the coil off thetray shown in broken lines;

  • FIG. 3 is a section, to larger scale, generally along line 3-3 of FIG. 2, showing in particular the capstan structure and its supporting means, the inclined rotating plow that moves turns of strand axially along the capstan, the gripper, and the receiving tray and movable guard;
  • FIG. 4 is a plan generally along line 4-4 of FIG. I but to larger scale, showing the capstan, the roller for holding strand turns on the capstan, the gripper, its latch means, strand severing means, and the stationary guard;
  • FIG. 5 is a detail along line 5-5 of FIG. 4 but to larger scale, of the latch means for holding the gripper;
  • FIG. 6 is a detail along line 6-6 of FIG. 4 but to larger scale, of the strand severing means
  • FIG. 7 diagrammatically illustrates the relationship of parts of the apparatus before start-up
  • FIG. 8 diagrammatically shows the beginning of start-up in which the lead end of the strand is passed through the die and grasped by the capstan gripper, the receiving tray being in its uppermost position and the die being in its lowermost position;
  • FIG. 9 diagrammatically illustrates completion of the initial winding of the strand on the capstan
  • FIG. 10 diagrammatically shows the drawing operation in which the strand level winds on the capstan and strand turns discharge from the free end of the capstan onto the receiving tray;
  • FIG. 11 diagrammatically illustrates another step in the drawing operation when the strand on the payoff tray is becoming exhausted
  • FIG. 12 diagrammatically shows conditions at the completion of the drawing operation, after the receiving tray carrying the coil of drawn strand has moved downwardly;
  • FIG. I3 diagrammatically illustrates the removal of the coil of drawn strand off the payoff tray onto a conveyor.
  • the illustrated apparatus (FIGS. 1, 2, 3 and 4) comprises a base 1 supporting a power rotated drum or capstan 2 for rotation about a vertical axis A at automatically controlled speeds and cycles of starting and stopping.
  • a strand S to be drawn passes to the capstan from a suitable source, such as a coil C on a conventional payoff tray 3 that is supported for rotation about a generally vertical axis to permit the strand to unwind from coil C.
  • Strand collecting means extending generally radially of and rotatable about axis A is provided below the capstan; in this embodiment it is a receiving tray 4 rotatable I about the axis A and adapted to be raised to the position shown in full lines 4 and lowered to a position shown in broken lines 4' in FIG. 1.
  • the apparatus also includes die means 5 for reducing the cross section of the strand, movable vertically between an uppermost position shown in full lines and a lowermost positionshown in broken lines in FIG. 1.
  • Base 1 also carries guide means 6 that carries the die means for vertical movement.
  • the capstan is positively rotated as required by anelectric motor that drives the capstan through a suitable gear box 8.
  • Turns T of strand are wound on the capstan in number suffi' cient to cause the strand to engage the capstan'with enough friction to prevent slippage as the strand is drawn through the die means 5.
  • a gripper 11 is mounted on the capstan. The gripper is adapted to grasp firmly the leading end of the strand S after it is passed through the die means, and hold it on the capstan as it is rotated a predetermined numberof times by conventional means to wind the desired number of helical turns of strand in a single layer on the capstan.
  • the die means 5 the position of which is shown in broken lines 5' in FIG. 1 when the gripper first grasps the leading end of the strand, is caused to 'move upwardly in a path parallel to the axis of the capstan at a rapid rate, to cause a number of widely spaced turns of strand to wind initially in a single layer on the capstan (FIG. 9).
  • the die means 5 is then in the position shown in full lines in FIG. 1 in which the strand leaving die means 5 travels in a straight path to the capstan in a path lying essentially in a-plane normal to the axis A of the capstan.
  • a rotating plow 12 is mounted to rotate with and about the capstan in a plane at an angle other than normal to the axis of rotation of the capstan. This plow forces the turns away from the location on which they first contact the capstan, so that each increment of strand winding onto the capstan directly engages the surface of the plow, and so abutting tu'rns are level wound on the capstan and pushed toward the free end of the capstan by the action of the plow acting through all turns on the capstan.
  • a snubber roller 13 (FIG. 2) is provided to be moved toward and engage the turns of strand on the capstan so that after the gripper has released the strand the turns of the strand will be maintained properly on the capstan.
  • the receiving tray 4 has been raised until its upper surface 14 contacts and frictionally engages the lowermost surface 15 at the free end of the capstan so tray 4 rotates with the capstan.
  • the capstan issurrounded by a stationary guard 16 that is appropriately apertured to clear the die means 5, the snubber roller 13, and other parts.
  • the lower end of the stationary guard carries a movable guard 17 that is capable of rotating with the receiving tray 4 relative to the stationary guard 16 when the bottom of the movable guard frictionally engages the top of the raised receiving tray and is lifted by this tray from its supporting means l8 on the stationary guard 16 so movable guard 17 can rotate freely.
  • the strand is then released from gripper 11, preferably by severing the strand adjacent the gripper.
  • the drawn strand leaving die means 5 is-level wound on the rotating capstan in a single layer of turns which abut and are forced axially of the capstan toward its free end by plow 12; the turns discharge over the free end of the capstan, the capstan portion 19 adjacent its free end preferably being smaller in cross section to facilitate this.
  • the discharged turns of strand drop onto the receiving tray where they are caused to form a coil D (FIGS. 11-13) in the space between the smaller end portion 19 of the capstan and the rotating guard 17.
  • the receiving tray carrying the coil D of drawn strand is then lowered to its lowermost position 4. While in this position, the coil is pushed off the receiving tray onto a suitable conveyor 20 (FIGS. 12, 13) by pusher means 21.
  • the die means 5 comprises a conventional holder 22 that carries adjustable straightening rolls 23 and a die box 24 holding a manually changeable draw die 25 and guide 26 (FIG. 2).
  • Holder 22 is mounted in a known manner for limited movements on a member 27 that CAPSTAN AND ASSOCIATED MECHANISM FIGS. 1, 2, 3 and 4 illustrate the capstan 2 and its supporting and driving means.
  • the capstan is supported by a shaft 3! that is journaled in the base 1 and has a tapered outboard end 32.

Portions 35, 36 and 19 are rigidly connected.
  • the gripper 11 is of known construction and comprises a member 37 pivotally mounted on the capstan within its larger portion 35, and a member 38 pivotally mounted on member 37.
  • Member 38 carries movable gripper jaws "39 that are suitably actuated by know means to grip the leading end of the strand as required.
  • member 37 can swing to position 37' where it projects beyond the periphery of wall 35, stop means 40, 41 limiting such swing, and member 38 can swing to position 38' relative to member 37, stop means 42, 43 limiting such swing relative to member 37; a tension spring 44 biases the member 38 to its straight position relative to member 37.
  • Latch means 45 (FIGS. 4 and 5) operating between the gripper member 38 and capstan 2 normally holds the member 38 and its supporting member 37 in their innermost positions. It comprises a latch member 46 (FIGS. 4 and 5) pivotally mounted on a bracket 47 fixed inside capstan 2 and having a latch 48 that normally engages a keeper 49 on gripper member 38.
  • the latch member is normally held engaged by member 51 biased by compression spring 52, but can be pushed into unlocked position shown in broken lines in FIG. 5 by piston rod 53 of fluid cylinder 54. Once released by the latch means, gripper members 37 and 38 may be pushed to their extended positions 37', 38' by fluid cylinder 55 controlled by conventional means.
  • Strand severing means 56 (FIGS. 4 and 6) is provided in the capstan to sever the 'end of the strand in the gripper from the remainder of the strand when the strand is to be released from the gripper.
  • This means includes a bracket 57 mounted in the capstan and having a portion through which the strand passes to the gripper between two normally open pivotally mounted cutting blades 58 and 59 (FIG. 6). At the appropriate time, these blades are brought together to cut the strand, as by a suitable linkage actuated by fluid cylinder 60 controlled by suitable known means.

  • the roller 13 is long enough to extend substantially over the entire length of the portion of the larger diametered surface of the capstan that carries the wound strand turns.
  • the roller is mounted for rotation about an axis parallel to the capstan, on an arm structure 62 that is pivotally supported by the base of the apparatus and can be moved at appropriate timesso the snubber roller engages the strand turns on the capstan and so the snubber roller is positioned at 13' away from the capstan, by a piston rod 63 of a fluid cylinder 64 (FIGS.

  • the rotating plow 12 (FIGS. 1, 3, and 7-13), comprises an annular continuous plow ring 75 located outside of and around the large portion 35.0f the capstan near its supported end.
  • This ring is supported by a generally radial member 76 mounted on a hub 77 that is supported by suitable bearing means 78 so that member 76 and the ring 75 rotate about an axis that is inclined to the axis A of the capstan shaft.
  • Ring 75 and member 76 are caused to rotate with the capstan by a pin 79 mounted in a bracket 80 in the capstan and projecting through an opening 82 in member 76.
  • the plow ring therefore, always rotates in a fixed plane that is inclined to the axis of rotation of the capstan, the position, direction, and degree of inclination being such that when the strand S is passing to the capstan in a plane normal to the axis of rotation A of the capstan, the first turn of strand winding on the capstan clears the plow ring 75 at the location where the strand first contacts the capstan but thereafter is engaged by the plow ring and pushed axially of the capstan toward its free end.
  • Each turn also pushes the next adjacent previously applied turn and so that in turn is mounted on the piston rods 93 and 94 oftwo associated fluid cylinders 95 and 96 that cooperate to raise and lower the receiving tray while preventing rotation of supporton, so that all turns are moved axially of the capstan as it rotates and additional strand turns are wound on it, until the turns are discharged from over the free end of the capstan.
  • the stationary guard 16 (FIGS. 1, 2 and 3) has a generally cylindrical inside surface and is fixed to a support 83 supported by base 1 above the capstan. This guard is suitably apertured to clear the die means and its supporting means, and the snubber roller. As shown in FIGS. 2 and 4 the arm 62 for the snubber roller also carries a guard 84 that cooperates with the stationary guard to close the opening for the snubber roller and its supporting means when the snubber roller is in its retracted position for safety during winding of the initial strand turns on the capstan. Guard 16 carries, circumferentially spaced around its lower portion, brackets 18 each having an inwardly facing groove 86.
  • Members 18 support and guide the lower movable guard 17, which has a generally cylindrical inner surface, by an outwardly facing annular ring member 87 fixed to the top of guard 17 and slidably fitting in grooves 86.
  • Members 18 and 87 are formed of materials, preferably metals, that are wear resistant and have low friction.
  • the lower edge of guard 17 also rigidly carries a ring member 88 formed of wear-resistant material providing high friction on engagement with the top of the receiving tray 4, and which fits over the outer edge of the receiving tray to prevent any gap through which a strand turn might escape or become jammed.
  • the receiving tray 4 has a top table portion 89 with flat outer edges, which is reinforced by frame members 90 and supported for rotation on a member 92 ing member 92.
  • Fluid cylinder 95 is supplied with fluid to cause the desired raising and lowering at the appropriate times by suitable conventional means not shown.
