Definitions

  • the present invention relates to paper sheet y separating and feeding machines wherein the sheets are separated one by one from a pack and each so separated sheet delivered to a printing press or other machine.
  • and feeding machines are usually provided with a single set of sheet grippers, preferably of the suction type, which are operatively connected together in unison through a system of links and cams to a driven shaft all of which limit the speed of delivery to the printing press and a primary object of the present invention is to generally improve sheet separating and feeding machines of this character whereby the sheets may be delivered in a more rapid manner.
  • Another equally important object of the invention is to arrange sheet grippers in sets upon a conventional separating and feeding machine and alternate the movement of each set of sheet grippers whereupon as one set of grippers move a sheet forward upon a pack towards the printing press another set of grippers will simultaneously seize or grip the next succeeding sheet of paper upon the pack and in this manner accelerate the delivery of the sheets of paper to the printing press without increasing the speed of the machine or exerting any undue strains upon the system of links and cams thereof.
  • Fig. 1 is a fragmental vertical sectional view of the machine embodying the invention as arranged above a pile or pack of paper sheets and,
  • Fig. 2 is a detail top plan view of the same.
  • I designates a pile or pack of paper sheets to be delivered to the feed rollers B of a conveyor and which latter in turn delivers the sheets to a printing press or other machines.
  • the shaft I has keyed thereto four cams indicated by the reference characters 3a, 3b, 3c and 3d. Whereas, these cams are each arranged upon the shaft in spaced relation the cams 3a and 3d are set at 180 in relation to the cams 3b and 3c. Also keyed to this shaft 2 are cams 5a, 5b, 5c, and 5d and the cams 5a, and 5d are set at 180 in relation to the cams 5b and 5c.
  • the cams 3a, 3d and 5a and 5d have a striking action at the same period of time, whereas the cams 3b,
  • Such sheet separating H CFI 2 3c, 5b and 5c also strike at the same time, but only after the shaft 2 rotates 180 after the cams 3a, 3d, 5a and 5d have struck or upon each complete rotation of the shaft 2 each set of cams is presented for striking action.
  • crank levers Pivotally supported upon the fixed shaft 'I are four bell crank levers each having a downwardly extending long arm indicated by the reference characters 8a, 8b, 8c and 8d. Pivotally connected to the lower end of each long arm of the bell. crank levers is a bar and the latterare indicatedv by the reference characters Illa, I0b, vlilo and Iild.Y Carried by the outer extremity of each bar is a, suction cup or foot indicated by the reference: characters 9a, 9b, 9c and 9d. Journalled upon the long arm of each bell crank lever is a roller IIa, Ilb, IIc and Ild.
  • a coil spring is connected to the short arm of each bell crank lever and is indicated by the reference characters I2a, I2b,l I2c and
  • Connected ⁇ to each bar is one end of a link and these links are indicated by the reference characters I3a, I3b, I3c ⁇ and I3d.
  • the opposite end of each link is pivotally connected to a crank arm rotatably mounted upon the shaft I5 and is herein indicated by the reference characters Illa, IIb, I4c and Idd.
  • the cams 5a and 5d will permit the suction cups Ba and 9d to grasp a single sheet of paper upon the top of the pile I and then the cams 3a and 3d will strike the rollers Ila and IId for advancing the so gripped sheet of paper until it assumes the position as indicated by the letter A in Figure 1 of the drawings.
  • the cams 5b and 5c will then permit the suction cups 9b and 9c to engage the exposed end of the next sheet of paper upon the pile I and as the cups 9b and 9c grasp this latter sheet of paper the vacuum within the cups 9a and 9d will be broken to release the sheet A.
  • An apparatus for separating sheets from a stack of horizontally disposed sheets and moving the separated sheets across said stack in quick succession comprising a rotary drive shaft, a A.pair of cam ⁇ sets -flxedly ⁇ ,mounted on .said shaft ,with a angle between each set, a plurality of vertically extending bell crank levers pivotally mounted with each lever contacting one of said cams lfor being pivoted thereby, resilient means retaining .each lever -in contact with its respective cam, a plurality of horizontal arms each piv- Votallyconnected to one of said levers, a plurality of.suction cups each carried by one of said arms, a second pair of camsets fixedly mounted on said shaft with an 180 angle between each set and with each set having the same striking position as 'one set of said rst mentioned group of cams, a second plurality of horizontal arms each bearingononefof-said second group of cams, a y.plu- 2ijality of-link
