Definitions

  • the present invention relates generally to sheet feeding devices and more particularly, a device feeding, positioning and turning documents from one side to the other.
  • the devices of the prior art turning sheets from one side to the other are generally bulky and / or unreliable. Many of these devices use multiple endless drive belts and associated pulleys to drive and orient documents on the desired feed path. Other devices use spring arms to grip the edge of the sheets at the periphery of a roll. These devices often have to be subject to precise mechanical adjustments with regard to the force with which they seize the documents as well as with regard to their release.
  • the present invention consists of a simple and efficient structure for turning over documents, comprising a rotary cylindrical transfer element having slots for receiving the leading edge of the sheets to be turned over, a retaining means closing the receiving slots for retaining the edge of the sheet during part of the rotation of the cylindrical element, said retaining means being designed to open the reception slot when the latter is in the document reception position and when the cylindrical element has been rotated in document release position, said document cylindrical element which can rotate freely and the slit being designed so that the force applied by the document penetrating the slit against the bottom thereof, initiates the rotation of the cylindrical element and causes it to rotate 180 ° through the application of additional force by a feed roller.
  • FIGS 1 and 2 are schematic representations of the preferred embodiment of the device of the present invention.
  • a sheet feeding path 15 receives a sheet to be returned from the output of a printing device or a reproduction machine not shown.
  • the feed path 15 can be made of a metallic fabric or a rigid material, for example sheet metal or plastic.
  • the sheet to be turned over arrives from the left side of the feed path 15 and is stressed by the drive roller 4 and the guide roller 5 which may be continuous cylindrical rollers of length equal to or less than the width of the path 15.
  • the drive roller 4 and the guide roller 5 are single rollers, these could be cylindrical rollers multiples mounted one after the other but separated by a certain interval, on a shaft arranged over the entire width of the feed path 15.
  • the drive roller 4 is mounted coaxially with the pinion 9 on the shaft 25.
  • the force driving the roller 4 is applied to the shaft 25 by the pinion 9 itself driven by the main control unit 16 which may consist of a pinion mounted on the shaft of an electric motor, or the pinion 9 can be driven by any other drive device of the system not shown in the figure.
  • the guide roller 5 is biased against the drive roller 4 by the spring 17, one end of which is fixed to the arm carrying the shaft on which the guide roller is mounted 5.
  • This guide roller support arm is pivotally mounted in 26.
  • the drive roller 4 in combination with the guide roller 5 drives the sheets into the turning roller 6.
  • the turning roller 6 is composed of a number of cylindrical rollers mounted one after the other but separated by a certain interval, on a shaft.
  • Each turning roller 6 has two slots 18, 18 ′ with flared entry and separated by 180 ° on the periphery of said turning roller in which the edge of the sheets to be turned is engaged.
  • the flared entry of each of the slots 18, 18 ′ has a more open side 23, 23 ′ which acts as a guide surface for the edge of the sheet penetrating into the slot.
  • the slots 18, 18 'with flared opening are machined in the mass of the turning rollers 6, so that the force applied against their closed end 19, 19' by the engaged sheet has the same effect as a tangential force applied to the surface of the turning rollers 6 to start their rotation.
  • the turning rollers 6 are fixed to a shaft which rotates freely and they normally occupy position A.
  • the shaft can also be mounted in a fixed position and the rollers rotate freely on the shaft.
  • a feed roller 7 is mounted on a shaft in a position adjacent to the turning rollers 6 and is carried by a pivoting arm 8 which rotates freely on the shaft 25 of the drive roller.
  • the feed roller 7 is driven by the pinion 24 which meshes with the pinion 9 of the drive roller.
  • the gear ratio of the feed roller pinion 24 and the drive roller pinion 9 is chosen so that the peripheral speed of the feed roller 24 is equal to or slightly lower than that of the drive roller 4.
  • the feed roller 7 is biased against the turning rollers 6 by the spring 17 and the eccentric stop 10 prevents it from biasing the flared side 23 of the slots 19 machined in the turning rollers.
  • the feed roller 7 consists of a single cylindrical roller of a length allowing the loading of all the turning rollers 6.
  • the feed rollers 7 could be composed of several rollers mounted one at a time. following the others and adjacent to the turning rollers 6.
  • An element 11 for retaining the edge of the sheets introduced into the slots 18 is fixed to the end of each turning roller 6 and slides while being guided by the pins 20 and 21.
  • the retaining element 11 has elongated buttonholes in which are housed the pins 20 and 21 as well as the shaft of the turning rollers, and is movable in translation until its race is stopped by one of the edges of each slot 18 opposite the flared sides 23.
  • a flexible blade 12 is arranged so that its inclined end 12 'bears against the circular guide surface 22 projecting from each retaining element 11 and tends to slide the retaining element as soon as it has exceeded an angular position corresponding to the 'angle of the inclined end 12' of the blade 12 (position B).
  • the flexible blade 12 also acts as the front wall of the output bin 13 and tends to release the edge of the sheet 14 from the slot 18 of the return roller. once the turnaround has been executed.
  • the sheet 14 arrives via the feed path 15 and is gripped between the drive roller 4 and the guide roller 5.
  • the turning rollers 6 are arranged at A and the drive roller 4 drives the sheet 14 in the slot 18 with a flared opening, formed in the turning rollers 6.
  • the roller 4 continues to push the sheet 14, which causes rotation turning rollers 6 at position B.
  • the feed roller 7 urges their outer surface via the sheet 14. The feed roller 7 rotates the turning rollers 6 and the sheet 14 to position C.
  • the retaining element 11 is tilted in the high position by the bent part 12 'of the flexible blade 12 in order to block the edge of the sheet 14 against the e upper rectilinear edge of the slot 18 in order to hold said sheet 14 there.
  • the feed roller 7 is released from their periphery due to the flared side 23 of the slot 18 which arrives in a position adjacent to the feed roller 7 and the eccentric stop 10 prohibited any movement of the arm 8.
  • the turning rollers 6 are then no longer driven by the roller 7, but the driving roller 4 continues to push the sheet 14 until the rear edge of the latter has exceeded this roller .
  • the front edge of the sheet 14 is now always retained in the slot 18 of the turning rollers 6 while the rest of the sheet rests on the stack of the output tray 13.
  • the end 12 ′ of the flexible blade 12 causes the element to slide. retaining ment 11 as soon as it has exceeded the angular position B to block the second sheet in the second slot 18 and at the same time to release the first sheet resting on the top of the stack of the output bin 13. Simultaneously, the front edge of the first sheet resting on the top of the stack of the output bin 13 and which is still in the first slot 18, bears against the flexible blade 12, which releases it from said first slot 18. This operation is repeated for each sheet to be returned arriving by the feed path.
