Definitions

  • the present invention concerns so-called reel cones which are used toform a connection between the tube forming the central support for a roll of printing paper and a controllable rotary member incorporated in a reel stand.
  • Reel stands are made in various forms and usually include a rotation controlling device such as a friction brake and/or a torque motor;
  • An object of the present invention is to provide a reel cone which obviates the foregoing disadvantages, avoiding damage to the tube and thereby enabling its re-use time after time.
  • the expandible tubeengaging means is preferably substantially cylindrical in its contracted condition and may for example be of rubber.
  • the expansion in diameter may conveniently be accompanied by an axial displacement and/or cont-raction which on tightening may serve to improve or maintain endwise engagement between the tube and a conical surface of the reel cone whilst when loosened serves to effect disengagement therebetween.
  • Expansion is preferably effected by axially compressing a cylindrical rubber member constituting the tube engaging means, by action of a screw operating between two relatively displaceable rigid parts of the reel cone.
  • Means are also preferably included for limiting the amount of such axial compression and there may be other means for preventing complete separation by disengagement of the screw.
  • Figure 1 is an axial longitudinal section on the line I-I of Fig. 2, partly in elevation;
  • Fig. 2 is a left hand end view
  • Fig. 3 is a right hand end view
  • Fig. 4 is a section on the line IV--IV of Fig. 1.
  • a reel cone constructed in accordance with the present invention comprises a hollow flanged body 12 adapted to be engaged on the spindle end 13a forming part of the rotary member of a reel stand 13, and an expandible rubber cylinder 14. carried by the body 12.
  • the reel cone is adapted to fit freely within the outer end portion of a tube 15, upon which aroll of paper (not shown) has been wound, when the cylinder 14 is in a contracted condition as shown in full lines in Fig. 1.
  • the rubber cylinder 14 On expansion to a position indicated by chain dotted lines, in a manner to be described, the rubber cylinder 14 is engaged firmly within. the tube 15 over a substantial area of contact.
  • the body 12 is flanged externally at 12a and adjacent to this flange presents an externally frusto-conical surface 125.
  • the flange 12a is interrupted by two chordal. flats 12c which. enable the body 12 to be gripped such. as when engaging or disengaging the body with or from the reel centre or reel stand rotary member...
  • the body is axially bored at 12d with an axial counterbore 12a, is radially bored at 12 and provided with three tapped. bores 12g which extend in a direction parallel to the axis of the body. Beyond the frusto-conical portion 12b the body is externally cylindrical at 12h, the diameter of this portion being slightly less than the internal diameter of the tube 15.
  • a compression screw 16 having a square. head 16a, a smaller cylindrical end portion 16b, 8. larger cylindrical end portion and a cylindrical shank 16d is retained in the axial position shown, relative to the body 12 by a retaining plate 17 having a bore through which the screw shank 16d passes freely and which is secured to the body by means of three Allen screws 18.
  • the screw 16 is preferably acme-threaded.
  • the dimensioning of the screw portions 16b and 160 relative to that of the bores 12d and 12a in the body is such that the screw is freely rotatable within the body by means of a key or spanner applied to its head 16a but is substantially incapable of axial displacement therein.
  • the radial bore 12 serves as an oil introduction hole.
  • the plate 17 In addition to three counterbored bores receiving the attachment screws 18 the plate 17 also has three tapped bores in which are engaged threaded end portions of guide rods 19 which are spaced at equal angular intervals on a pitch circle coaxial with the body 12 alternately with the screws 18.
  • the rubber cylinder 14 has an axial bore to accept the screw shank 16d and three bores disposed at spaced intervals around a coaxial pitch circle and dimensioned to accept the guide rods 19 freely fitting therein.
  • An end plate 20 has an axial tapped bore 20a within which the screw 16 engages, this bore being counterbored at 2011 to accept part of the axial length of the screw shank 16:1.
  • the end plate also has three bores 20c appropriately positioned to receive the end portions of the three guide rods 19.
  • This end plate has an externally cylindrical surface 20d of a diameter substantially less than that of the tube 15 and a frusto-conical end portion 20c.
  • a stop nut 21 is secured by a pin 22 at the end of the screw 16.
  • the reel cone in the contracted condition as shown, is introduced into the end portion of the tube forming the center of the roll of paper.
  • a box spanner is applied to the square end 16a of the screw which is rotated within the body thereby drawing the end plate, which is prevented from rotating relative to the body by the guide rods, towards the body until a terminal position of the shank 16d within the counterbore 20b obtains.
  • This movement of the end plate applies axial compression to the rubber cylinder 14 deforming its initially cylindrical external surface into-a larger. diameter as shown in chain-dotted lines most of which bears firmly upon the interior surface of the tube 15.
  • a threaded driving pin 23 engaged in a radial tapped bore in the body 12 may be provided for ensuring positive engagement between the body and the rotary member of the reel stand.
  • a reel cone for connecting the central tube in a paper roll to a rotary member on a reel stand, said reel cone comprising a body member of smaller diameter at one end than the other, which latter end is adapted for connection to said rotary member, an end plate carried by said smaller diameter end of said body member in spaced relation therewith, a cylindrical expandible tube-engaging element mounted between said smaller diameter end of said body member and said end plate and adapted, together with said smaller diameter end and said plate for insertion within the central tube in a paper roll, guide means extending from said body member and projecting through said element to said end plate to prevent relative rotation between said member and said plate, and displacement means also extending from said body member through said element and projecting into said end plate and arranged for actuation to move said plate along said guide means to alter the spacing of said plate from said body member, whereby, on insertion of the reel cone in the central tube of a paper roll, actuation of said displacement means causes said element to be compressed between said smaller diameter end of said body member and said end plate and thereby to
