Definitions

  • ABSTRACT A clamping mechanism for clamping upon a rotatable shaft a split rotary anvil or the like and comprising c0- operating male and female clamping members provided on respective mating ends of the anvil, each male member being pivotally attached to its mating end and having a camming surface engageable by camming means of the respective mating end having a female member.
  • the present invention relates generaliy to rotary die cutting, and particularly relates to clamping mechanisms for clamping split rotary anvils, split heads and the like to rotatable shafts.
  • material to be cut is fed into the nip of a pair of rotating rollers wherein one roller is equipped with radially extending cutting edges (the rotary die), and the other roller (the anvil) is equipped with a surface upon which the cutting edges qf the die may bear during the cutting operation.
  • the surface of the anvil may be of metal, but more desirably is a replaceable cover of resilient material such as polyurethane plastic and the like.
  • the anvil upon which such a resilient cover may be placed is clamped onto a rotatable shaft, rotational slip between the anvil and the shaft being prevented by the use of slot pins, tongue-and-groove assemblies, or the clamping action alone of the anvil.
  • the rotary die may be fastened to split head members (commonly called T slot heads) which in turn are mounted in similar fashion to a rotatable shaft. See, for example, U.S. Pat. Nos. 3,274,873; 3,282,142 and 3,285,642.
  • a rotatable shaft may be provided with one or more anvils, T slot heads and the like clamped in succession along its length, and it is important that these members individually be capable of quick and easy removal from the shaft. To accomplish this, these members may be provided in two or more portions (e.g. split" portions). Although rotary movement of such members with respect to the shaft may be constrained by the aforesaid tongue-and-groove assembly or the like, it is also of important that they be clamped securely and tightly to the shaft so as to prevent any rotary or axial movement thereof with respect to the shaft and to permit extremely accurate positioning thereof on the shaft.
  • U.S. Pat. No. 3,285,642 lmer alia describes split rotary anvils wherein the clamping mechanism includes a hook-spaced latching link, clamping being accomplished by bringing the split anvil members together, hooking the latching link attached to one arcuate anvil portion about a fixed member of an adjacent arcuate anvil portion, and urging by means of a camming device, the arcuate portion into a clamped position about the rotatable shaft. Locking the clamping device, as a safety measure so the anvil cannot accidentaly loosen and come off the shaft, is accomplished by actuating a second camming shaft against the top of the hook shaped latching link.
  • the split anvil sections should be capable of being clamped together upon a shaft with accuracy and strength, and shouid further be capable of being loosened for movement along the shaft or removed altogether easily and without binding or other problems associated with prior art clamping devices, and should include a lock for locking the clamping mechanism to prevent accidental loosening thereof.
  • FIG. I is a perspective view of a rotatable shaft with an anvil and cover of the present invention clamped thereto;
  • FIG. 2 is a perspective view of respective mating ends of a split anvil of the present invention;
  • FIG. 3 is an axial view of mating, arcuate portions of the split anvil of the invention ready to be clamped together;
  • FIG. 4 is a view, partially in cross section and partially broken away, taken along lines 4-4 of FIG. 3, showing the device of the present invention in the open, or un-clamped, position;
  • FIG. 5 is an axial view, in cross section, taken along lines 5-5 of FIG. 4;
  • FIG. 6 is a plan view of a rotary camming member shown also in FIGS. 4 and 5',
  • FIG. 7 is a cross sectional view taken along the lines 77 of FIG. 6;
  • FIG. 8 is an enlarged cross sectional view taken along lines 88 of FIG. 6.
  • the present invention relates to a clamping mechanism for clamping together respective mating ends of a split rotary anvil or the like upon a rotatable shaft.
  • the mechanism comprises cooperating male and female clamping members carried by said respective mating ends.
  • Each male member is pivotally attached to its respective mating end and has a camming surface so positioned as to tend to draw the male member from its pivotal attachment when force is applied to the camming surface.
  • Each female member is adapted to receive a respective male member and includes camming means adapted to engage and apply force to the camming surface of the male member thereby clamping the mating ends together.
  • the female members also preferably include locking means operatively coupled to the camming means for preventing movement of the latter after mating ends have been clamped together.
  • the respective mating ends include respective contact surfaces such that juxtaposition of the contact surfaces together upon clamping tends to bias opposed mating ends apart.
  • rotatable shaft 10 is provided with split rotary anvil I2 comprising arcuate portions 14 and 16, the latter being provided with slot 18 to receive key 20 of the rotatable shaft.
  • a resilient covering which may be polyurethane plastic
  • Mating ends 24 and 26 (FIG. 2) of arcuate anvil portions I4 and 16 are provided, respectively, with female and male locking memhers designated as orifice 28 and pin 30.
  • the outer periphery of the anvil may be provided with slots 32 for receiving appropriately shaped portions of the resilient covering.
  • Pin 30 has an annular notch or groove 34 therein adjacent its protruding end 36 to provide a camming surface 38 (as shown best in FIG.
  • Arcuate anvil portion 16 has an orifice 40 in its mating end 26 within which one end 42 of pin 30 is pivotally attached by means of transverse peg 44 which in turn is press-fitted into transverse hole 46 (FIGS. 4 and 5).
  • orifice 40 With reference to the axis of rotation of the rotation of the rotatable shaft 10, orifice 40 is slightly larger in the radial direction than in the axial direction, thereby permitting the pin 30, prior to insertion into orifice 28, to pivot axially about peg 4-4 as shown by arrow 48.
  • the protruding end 36 of the pin 30 is preferably provided with a slight taper or rounding to permit easy insertion thereof into orifice 28.
  • orifice 40 limits the pivotal motion of the pin 30.
  • the amount of pivotal motion allowed pin 30 is limited so that the protruding end 36 thereof will remain sufficiently within the entrance periphery 52 of orifice 28 so as to permit the tapered end 36 to be guided into the orifice 28 when mating, arcuate anvil portions 14 and 16 are brought together about the rotatable shaft 10.
  • the pivotal movement of pin 30 is limited so that the chord of the arc subtended by the protruding end 36 of the pin upon pivotal movement thereof is no greater than (and preferably from about to about 70 percent of) the diameter of the orifice 28 adapted to receive the pin.
  • the pivotal motion of pin 30 is critical to the present invention. This feature, for example, permits the arcuate anvil portions 14 and 16 to be clamped together and removed without significant binding of the pin 30 in the orifice 28.
  • the pivotal motion of pin 30 provides just enough play to make it easy for even an unskilled worker to quickly mount and remove an anvil of the invention from a rotatable shaft.
  • the pin 30 may be provided with a slightly smaller diameter throughout the leading (distal) portion of the protruding end, as shown in FIG.
  • mating ends 24 and 26 are preferably provided with respective cooperating contact surfaces shown as planar surfaces 57 and 58 which diverge outwardly from each other when the anvil is clamped about the rotatable shaft.
  • the contact surfaces 57 and 58 are positioned adjacent the inner periphery 61 of the anvil such that clamping of mating ends 24 and 26 together by means of pin 30 tends to pivot surfaces 57 and 58 into planar contact, thus urging opposed matings ends (not shown) of arcuate portions 14 and 16 on the opposite side of the rotatable shaft to separate.
  • the inner diameter of the anvil passing through at least one pair of juxtaposed mating ends be greater than the diameter normal thereto.
  • the mating ends of the arcuate portions will be separated by a small gap, which may, for example, be about 20 mils in width for anvil having about a l2 inch inner diameter.
  • Mating end 24 of arcuate anvil portion 14 is provided with a through-hole 59 transversely therethrough (axially with respect to shaft 10) bearing a rotatable dowel 60, the ends 62 and 64 of which dowel have hexagonal recesses 66 and 68 therein to receive an Allen wrench to facilitate rotation of dowel.
  • the transverse through hole 59 preferably is enlarged at its ends, the enlarged section accommodating ends 62 and 64 of the dowel being shown generally as 70 and 72, respectively.
  • the dowel 60 bears a geared surface 82, the purpose of which be explained below.
  • slots 74 and 76 are provided respectively in the ends of the dowel 60 to accommodate retaining springs 78 and 80 for retaining the dowel in the through-hole.
  • mating surface 1 14 of arcuate end portion 24 is provided with an internally threaded hole extending inwardly to dowel 60 at a point wherein the dowel has a circumferential groove such as slot 76.
  • the internally threaded hole is provided with a screw member threaded therein. The internal end of the screw member is adapted to ride within the circumferential groove in the dowel and to thus restrain the dowel from axial movement thereof within through-hole 59.
  • the external end of the screw member is adapted to extend outwardly from surface 114 a short distance (e.g., /4 inch).
  • the surface of arcuate end portion 26 which mates with surface 114 is provided with a recess therein adapted to loosely accommodate the external end of the screw member.
  • a two-piece split anvil having two separate mating halves
  • only one pair of mating surfaces is provided with the thus-described screw member and recess, thereby insuring that the same mating surfaces are oriented together when the anvil is clamped about a shaft.

Section 90 has a circular periphery 9! which acts as a camming surface and has a annular transverse groove 96 therein which preferably has a radius approximately the same as the radius of orifice 28.
  • the axis 94 of the dowel 60, the axis 98 of the orifice 28, and the circular groove 96 are preferably so positioned as to permit the surface of the annular groove 96 to become substantially co-planar with the inner circular surface 1000f the orifice 28 when the dowel is rotated to a predetermined position, as d igcus sed more fully below.
  • the surface of the dowel 60 is also provided at a point along its length adjacent end 62 thereof with circular detent depressions 102 and 104 therein.
