Definitions

  • closure v 269/481 means consists of a resilient body arranged, when actuated by an axially displaceable pressure rod to effect [56] References Cited closure or exposure of channels leading to said hoses.
  • the central body of the reeling-up drum is formed with grooves of T-shaped cross-sectional configuration, each one of these grooves housing a rubber hose which, when inflated, urge a longitudinally extending pressure element inserted in the groove radially outwards into engagement with the winding sleeve.
  • a roll sprindle or drum of this kind possesses a considerable load-bearing capacity.
  • the attachment of the roll on the spindle or drum is effected in that the pressure elements are urged with considerable force into the winding sleeve such that the pressure elements fix the roll relative to the longitudinal axis of the reeling-up drum.
  • air will, however, be pressed from the upper rubber hoses to those positioned at a lower level.
  • a pumping effect will arise resulting in deterioration of the retainment of the roll and displacement of the roll from the drive shaft centre.
  • valves mounted in connecting or junction channels in the reeling-up spindle so as to communicate with the hoses, these valves being normally closed but, upon actuation of operation means, being made to open to enable inflation of the hoses.
  • it has proved a complicated task to mount reliably operating closure valves in these junction channels in the reeling-up drum, and in addition, they make the roll spindle considerably more expensive.
  • the reeling-up drum comprises a means arranged for movement in said axial channel and adapted upon movement in one direction to close the inner end of all said radial junction channels.
  • FIG. 1 is a broken side view of a reeling-up drum, shown partly in longitudinal section, the reeling-up drum being provided with ajunction channel leading to one of the hoses as well as with a closure means in accordance with the invention.
  • FIG. 2 illustrates on an enlarged scale a crosssection through the reeling-up drum along line IIII of FIG. 1, the reeling-up drum pressure elements being in their radially outer position,
  • FIG. 3 shows a similar cross-sectional view with the pressure elements being in an inoperative position
  • FIG. 4 illustrates on an enlarged scale as compared with FIG. 1 a longitudinal section through the righthand trunnion of the reeling-up drum, the closure means being in operative (closed) position
  • FIG. 5 is a similar longitudinal section, the closure means being designed in accordance with a second embodiment and shown in its inoperative (open) position, and
  • FIG. 6 is a longitudinal section through a further embodiment with the closure means in its open position.
  • the central body 2 of the reelingup drum 1 illus trated in the drawings is formed with three longitudinally extending grooves 3, 4, and 5 each one of which houses a longitudinally extending rail member 6 forming the reeling-up drum pressure elements.
  • inflatable rubber hoses 7 which, when in flated, function to urge the rail members 6 radially outwards (FIG. 2).
  • the hoses 7 are sealingly compressed and urged against the bottom of their respective groove 3, 4, 0r 5 by means of a pressure plate 8 and a screw 9 passing through said plate.
  • a nipple I0 is inserted into one end of each hose.
  • the nipple extends into a radial channel 11 formed in the central body 2.
  • three such channels 11 debouch into one common, axially extending channel 12 which debouches at the outer end of the trunnion l3.
  • each rail member 6 is formed with stopping ribs 14, upon displacement radially outwards of the rail member these ribs will abut against abutment ribs 15 formed at the periphery of the reeling-up drum and engaging in the associated groove.
  • a rod-like pressure member 20 is axially displaceable in the channel 12, said rod having an axial bore 21 debouching via a radial channel 22 in a peripherally extending notch 23 in the rod-like pressure member 20.
  • a cylindrically formed plug 29 of rubber or similar resilient material is arranged at the inner end of the pressure rod 20, said plug being threaded onto an axial prolongation portion 30 of the pressure rod.
  • a washer 31 is axially displaceable on said prolongation portion 30 and by means of a helical spring 32 is urged against the inner end surface of the resilient body 29. This compresses the resilient body 29 somewhat in the axial direction such that it will abut peripherally against the jacket face of the channel 12 closing oi? the inner end of the junction channels 11.
  • the pressure rod 20 When the pressure rod 20 is displaced inwards against the action of the spring 32 the inner openings of the channels 11 are exposed, it being then possible to inflate the hoses 7 with pressurized air.
  • the hoses expand and displace the rail member 6 radially outwards into engagement with the winding sleeve 28, for instance a paper roll (not illustrated) which is threaded on the reeling-up drum 1.
  • the air pressure will remain at the same level in all hoses 7 ensuring good centering of the winding sleeve 28 during the reeling-up operation.
  • the rod together with the closure body 29 will be moved under the action of the spring 32 into the closure position illustrated in FIG. 4, in which position the communication between the hoses is interrupted.
  • the pressure rod 20 it is likewise possible to displace the pressure rod 20 to its various positions by manipulating the sleeve 26 by means of the fingers of one hand.
  • FIG. 5 A simplified embodiment of the invention is illustrated in FIG. 5.
  • the closure means consists of a cylindrical body 33 made from rubber or a similar resilient material and in serted into the inner end of the channel 12.
  • the diameter of the closure body 33 is slightly less than that of channel 12 whereby air is allowed to pass into the an nular gap thus formed between the closure body and the jacket surface of the channel 12.
  • the pressure rod 20 is provided with a threaded portion 34 the external threads of which mate with internal threads 35 at the outer end of the trunnion 13'. When the pressure rod 20' is screwed into the channel 12 the resilient body 33 is compressed and then closes the inner end of the channels 11, thus interrupting the communication between the hoses 7.
  • the outer end of the pressure rod may be provided with a non-return valve 36 ofa nature permitting sealing against a seat at the occurrence of an internal pressure inside the hoses 7.
  • a non-return valve 36 ofa nature permitting sealing against a seat at the occurrence of an internal pressure inside the hoses 7.
  • FIG. 6 An improved embodiment of the drum of FIG. providing for simplified inflation of the reeling-up drum is illustrated in FIG. 6.
  • the rod-like pressure member 20" in accordance with this embodiment is provided at one of its ends with a piston 37 and a sealing 43 therefor.
  • the piston is movable in a cylindrical chamber 40 formed in the trunnion 13''.
  • a compression spring 38 At the axially outer side of the piston 37 is positioned a compression spring 38, held between the piston and an end plug 39.
  • closure means to interrupt the connection with the hoses after inflation of the latter may be constructively altered in a variety of ways within the scope of the appended claims. Opening and interruption of the communication between the hoses may be effected through rotating the rod 20 instead of displacing it radially if the closure means and the inner rod end are designed accordingly.
