Definitions

  • This invention relates to apparatus for changing the po. sition of bar stock moving over a roll table.
  • the stock moves between two rollers, each carried on the end of a tong arm the two arms being pivotable about a common horizontal axis.
  • the arms can either be fixed in relation to the table or mounted on a bearer mounted for vertical movement in a truck movable along a gap below the roll table across the general direction of movement of the stock.
  • the tong arms have only been capable of pivoting through about 90- and have been moved by means of connecting rods involving a large number of links and levers.
  • such apparatus comprises a pair of tong arms each having a roller at its end whereby the stock may pass between the rollers, each arm being mounted so as to be rotatable through 180 about an axis common to both arms and perpendicular to the axes of the rollers, and having associated with it a rope or chain for rotating that arm independently of the other.
  • each arm is mounted on a wheel, the two wheels being rotatable about a common supporting shaft, and each wheel has the respective rope or chain extending around part of its periphery.
  • each rope or chain is endless and passes around a rotatable roller
  • the endless member includes a link in the form of a piston mounted to work within a cylinder fixed in relation to the member and having means whereby fluid may be introduced to each end to move the piston in opposite directions and thus rotate the associated arm in opposite senses.
  • FIGURE 1 is a side elevation, partly in section, of the apparatus
  • FIGURE 2 is similar to FIGURE 1 but with the section taken on a different plane along the line 11-11 in FIG. 3;
  • FIGURE 2a is similar to FIG. 2 but with the section taken on a different plane so as to show the hydraulic system;
  • FIGURE 3 is a vertical cross-section through the apparatus
  • FIGURE 4 is a plan view of part of the apparatus on an enlarged scale.
  • FIGURES S, 6 and 7 show the tong arms of the apparatus handling bar stock in various positions.
  • the apparatus is carrie on a truck 1 having wheels 2 and 2a which run on tracl in a gap below the roll table.
  • the roll table as such is n( shown, but one roller of the table is shown at 17 in FIG URES to '7, and it will be seen from these figures the the truck can be moved parallel to the axis of the rolle1 of the table, and thus transverse to the direction of mov ment of the bar stock over the table.
  • the wheel 2a of th truck is driven by a motor 3 through worm gearing 4.
  • the truck carries a bearer 5 which is mounted so th: said bearer can be moved vertically with respect to tl'. truck by means of hydraulic pressure.
  • the bearer is formed with a cylinder 6, and a piston 7 rigidly secured to a portion 1' of the truck by way of piston rod 7a passing through a gland in the bottom of ti cylinder.
  • the portion 1 of the truck extends through vertical slot 5' formed in bearer 5.
  • the bearer At its top end the bearer carries two tong arms 9 an 9', and both are mounted so as to be rotatable throng 180 about a common shaft 8.
  • the tong arms can rollers 10 and 10' respectively at their free ends in tl conventional manner.
  • Each arm is mounted on a who or pulley 11 and 11' respectively as can be seen in FK URES 2 and 3, and an endless flexible tension member i the form of a draw rope or chain 12 extends around di: 11, while a corresponding rope or chain 12' extends aroun the disc 11.
  • an endless flexible tension member i the form of a draw rope or chain 12 extends around di: 11, while a corresponding rope or chain 12' extends aroun the disc 11.
  • Each draw rope 12, 12' respectively pass around a rotatable roller 13, 13' at the lower end of ti bearer 5 and is connected to one end of a piston 14, 14 The other end of each piston is connected to a further fre end of the respective rope so that each rope and pistc together form an endless member.
  • the pistons 14 at 14' work in cylinders 15 and 15 respectively, and tl cylinders are rigidly connected to the bearer.
  • Fluid c2 be admitted to each end of either cylinder and the dimer sions of the pistons and cylinders are such that the pistol can move so far in either direction from their central pot tion that the wheel to which they are connected is rotate through in either sense, thus allowing each of the tor arms a possible rotation of
  • In order to grip the bar stock between the tong arms is necessary for them to be rotated independently so th they can be moved apart, and then together again to clan the stock between them.
  • tl arms must of course be moved together.
  • the two rollers 13 at 13 can be coupled to rotate together by way of a magnet coupling 16.
  • FIGURES 5 to 7 show how bar stock of various cros sections moving over a roll table can be picked up in at desired direction from below or from either side at turned through a complete semi-circle to be guided bar on to the roll table in any required angular position.
  • the bearer instead of moving rectilinear with respect to the truck 1 can be one arm of a bent leve the other arm of which is pivotally mounted on the trui about a horizontal axis parallel with the axles of the ru ning wheels 2 and 2a.
  • the draw ropes 1 tlHS extend by way of deflecting rollers as far as the arm unted in the truck 1, and their hydraulic drive can n be mounted on or in this arm.
  • a bearer constructed this way is particularly useful when the head room ow the roll table is small, or when the apparatus is posed not on a special truck as shown, but on a shifting aight edge.
  • the draw ropes or chains can alter- :ively be moved by rotation of the roller 13 or 13' and this case they are preferably fixed to the periphery this roller so that slipping cannot occur.
  • a pair of tong arms each ving a roller at one end freely rotatable about an axis ending substantially in the longitudinal direction of the pective arm, and a flexible tension member operatively mected to each of said arms for independently pivoting d arms with respect to each other through an angle of 3 about a pivot axis common to both arms, said pivot .s being perpendicular to the axes of said rollers and iidistant therefrom sothat the bar stock can be guided :ween said rollers as it moves over the roll table.
  • each flexible ,sion member is endless and passes around a rotatable ler.
  • Apparatus according to claim 2 in which the endless mber includes a link in the form of a piston mounted work within a cylinder fixed in relation to the member 1 having means whereby fluid may be introduced to :11 end to move the piston in opposite directions and IS pivot the associated arm in opposite senses.
  • the arms are 'otably supported by a bearer mounted on a truck having :ans whereby it can be moved along a track below a gap nsverse to the general direction of movement of the ck over the roll table, and means are provided for movthe bearer relative to the truck in a direction substanlly perpendicular to the plane of the surface of the roll ale. 5.
  • Apparatus according to claim 1 wherein said arms mounted on respective pulleyspivotable on a common sporting shaft, said shaft having an axis coinciding with d pivot axis, and said flexible tension members extend )und part of the periphery of the respective pulleys.
