Definitions

  • This invention relates to apparatus for renewing rolls of paper or similar material which are being fed to an apparatus using the material continuously. More particularly, it relates to apparatus for removing a nearly exhausted roll from its support without interfering with the rotation of the roll and for uniting the end of the nearly exhausted roll with a full roll placed upon the original support from which the nearly exhausted roll was taken.
  • Figure 1 is a partial end elevation of apparatus embodying the invention, with the parts in position for removing a partly exhausted roll;
  • Fig. 2 is similar to Fig. 1, but shows the parts in the position assumed when the partly exhausted roll is lifted from its original support;
  • Fig. 3 is a view similar to Figs. 1 and 2, but showing the partly exhausted roll removed from its original sup port and replaced by a full roll;
  • Fig. 4 is a partial plan view of the apparatus in the position disclosed in Fig. 3;
  • Fig. 5 is a detail view showing the end of the material on the full roll;
  • Fig. 6 is a detail view with the material in the full roll;
  • Fig. 7 isa detail View showing the exhausted roll core ready for removal.
  • the roll supporting shaft is mounted in end frames 16, one of which is shown in the drawings.
  • the end frame is provided with a bearing 17 "having rollers 18 upon which the shaft rests, so that the roll may be rotated easily.
  • the apparatus is particularly suitable for use with such devices as tube formers, where a sheet of paper is drawn from a roll and formed into a tube, and is very useful where a plurality of such sheets are superposed and formed into a multi-ply-tube. In such cases the position of the roll laterally of the sheet is important, in order that the sheets of paper may be properly superposed.
  • the shaft is formed with a groove 19.
  • a latch 20 is .adapted to fit in groove 19 when the shaft is properly positioned longitudinally, and to maintain this proper longitudinal position of the shaft, the latch is pivoted at 21 upon a carrying-head 22.
  • A. screw 23 passes through the carrying-head, and may be turned by means of a crank 24 in order to vary the position of the latch longitudinally during running of the apparatus, or to adjust the position of the roll at any time when necessary.
  • a spring 25 normally presses the latch upward against the shaft, so that it rises into the notch as soon as the shaft is in proper position.
  • a lever 26 is fulcrumed at 27 upon the frame of the apparatus and carries at one end a pedal 28 by means of which the lever may be operated.
  • a roll shifting device is supported upon legs 29 pivoted at 30 upon the end of lever 26. It will be understood that legs 29 are duplicated for each side of the apparatus, but one being shown in the drawings.
  • each leg 29 there is a bearing 31 provided with rollers 32 upon which the shaft of the roll may rest when the device is in operation- Supported upon leg 29 there is a latch 33.
  • the latch ' is supported adjustably so that it may be moved towards or from the leg as necessary in order to position it in the same plane with latch 20.
  • 'Leg 29 also carries brake arms 34 and 35, there being a link 36 pivoted to arm 34 and adapted to rest in arm 35, and carrying a nut 37 by which the arm may be tightened against a shaft supported upon rollers 32.
  • the maximum distance of the leg from the end frame may be adjustably fixed.
  • a stop 48 in position to limit the movement of the shifter leg, as shown in Figs. 1 and 2, so that thevbearing of the shifter is in proper position to raise the shaft.
  • retarding mechanism In order to prevent over-running of the roll upon slowing up or stopping the machine some form of retarding mechanism is customarily used. Preferably, this takes the form of a strip, or similar means, resting upon the roll and so exerting substantially uniform friction thereon at all times. No such means is shown in the drawings, but will be readily understood.
  • some similar retarding means When the roll is shifted from its normal position, some similar retarding means must be provided, and the brake consisting of arms 34, 35 with link 36 and nut 37 is provided for furnishing the necessary amountof retardation. Other means might be substituted therefor.
  • the two sheets may be allowed to move along together until roll 10 is completely exhausted, or the fabric may be out if desired, leaving a certain amount of unexhausted fabric upon the core.
  • latch 33 is thrown back, the brake is opened, placing the apparatus in condition for the removal of the exhausted .roll, as
  • a shaft supporting a roll of fabric and having a groove therein a support for the shaft having a'latch adapted to enter one side of the groove, a shifting device adapted to lift the shaft from the said support and move it to one side thereof Without interfering with its rotation, and a latch on the shifter adapted to enter the other side of said groove.
  • a support for a roll of fabric means to lift the roll from its support and shift it radially therefrom without interfering with the rotation of the roll, means to position the shifting apparatus so as to deliver fabric from the roll in a path sufliciently far from the original position of the roll to avoid contact with a full roll placed in the original position of said shifted roll, and means to move the fabric running from said shifted roll against the outer surface of a full roll placed in the original position of said shifted roll, said means comprising a flexible sheet adapted to yieldingly contact the fabric running from said shifted roll.
  • a support for a roll of fabric means to lift the roll from its support and shift it radially therefrom Without interfering with the rotation of the roll, means to position the shifting apparatus so as to deliver fabric from the roll in a path sufficiently far from the original position of the roll to avoid contact with a full roll placed in the original position of said shifted roll, and means to move the fabric running from said shifted roll against the outer surface of a full roll placed in the original position of said shifted roll, said means comprising arms carrying loops of stiff fabric such as leather and in position to contact the fabric from the shifted roll.
