Definitions

  • the present invention relates to a device for separating sheets into packages in an office machine such as a facsimile machine, and more particularly such a device comprising, in a known manner, an extraction roller, a support member pressed elastically in the direction of the roller. , and a stop limiting the maximum distance between the extraction roller and the support member, as well as a method for adjusting the stop of this device.
  • the sheets of paper to be treated can be presented in a packet, at least two, in a feeder, each above the others, against an extraction roller on the one hand, and a retaining pad on the other.
  • the rubber roller is arranged to drive these sheets one by one, those which are above the extracted sheet being retained by the pad also made of rubber. During its movement, and beyond the roller, a sheet passes between rollers of a drive rolling mill which bring it to its processing station.
  • the shoe In order to allow a sheet of paper to pass, the shoe must be able to move away from the extraction roller. This spacing must however be limited in order to prevent the passage of several sheets simultaneously between the roller and the shoe. To this end, provision is made, in known manner, for pressing the shoe in the direction of the extraction roller by means of a support member urged by elastic means, and to limit the movement of this support member using a stop.
  • This stop has the drawback of requiring very delicate adjustment, both during assembly of the machine and during maintenance operations.
  • the present invention aims to overcome these drawbacks.
  • the invention firstly relates to a device for separating sheets in packages in an office machine such as a fax machine, comprising an extraction roller, a support member pressed elastically in the direction of the roller, and a stop limiting the maximum distance between the extraction roller and the support member, characterized in that the stop is slidably mounted in a support piece in the direction of the support member, means elastic being provided to push said stopper in this direction, and locking means being provided to prevent said sliding.
  • the stop is substantially cylindrical and the elastic means comprise a helical spring bearing on the one hand on the support piece and, on the other hand, on a shoulder of the stop.
  • the locking means may in particular comprise a flange enclosing said stop.
  • the support member is itself slidably mounted on the support part.
  • This support member may more particularly comprise two lateral projections each engaged in a groove in the support piece.
  • the support piece may in particular comprise means for snapping onto the frame of said office machine.
  • the device according to the invention therefore reduces the adjustment of the stop to a minimum of operations.
  • the calibrated wedge whose thickness is equal to the clearance that the one wishes for the support member.
  • the locking means are then loosened, thus releasing the stop which, under the action of the elastic means, comes into contact with the support member and presses it against the wedge, itself in contact with the extraction roller.
  • the adjustment operation therefore consists solely in setting up the calibrated shim and in loosening and then tightening the means for blocking the stop.
  • the precision of the adjustment of the stop is therefore the precision obtained on the thickness of the shim. It is thus possible to improve the operation of the sheet separation device.
  • the invention also saves time during assembly of the office machine comprising the device.
  • the device shown in Figure 1 comprises a support piece 1, provided with tabs 2 for snapping onto the frame 3 of an office machine such as a fax machine.
  • the support piece 1 forms a tubular housing 4 inside which is disposed a cylindrical stopper 5.
  • the stopper 5 comprises a tail 6 of smaller diameter forming a shoulder 7 and delimiting with the tubular housing 4 an annular space 8, in which a helical spring 9 is disposed bearing on the one hand on the shoulder 7 and, on the other hand, on a wall 10 at the end of the housing 4, the tail 6 of the stop 5 passing through this wall 10.
  • a flange 11 produced here in one piece with the support piece 1 makes it possible to block the stop 5 in translation in its housing 4.
  • the flange 11 surrounds the stop 5 and its end is tightened using 'a screw 12 engaged in a hole 13 of the part 1.
  • the device according to the invention also comprises a support member 14 with a V section, also slidingly mounted in the support part 1.
  • the support member 14 comprises two lateral projections 15 each engaged between the two branches 16 a hairpin piece integral with the support piece 1, the two branches 16 of each hairpin defining between them a sliding groove for the corresponding projection 15.
  • a helical spring 17 disposed around the stop 5 is supported, on the one hand on the support part 1 and, on the other hand, on the support member 14 which it biases in the direction of a roller d extraction of sheets 18 mounted on the frame 3.
  • the support member 14 is therefore sliding between two stop positions, one where it is in support on the stop 5 away from the roller 18, and the other where it is in support on the parts. hairpin near the roller 18.
  • the support member 14 and the spring 17 are put in place in the support piece as well as the spring 9 and the stopper 5.
  • the latter is brought into its position shown at FIG. 2, with the compressed spring 9, position in which it is held in place by tightening the screw 12.
  • the assembly thus configured is snapped onto the frame 3 of the machine with the support member 14 facing the extraction roller 18.
  • a shim 19 of thickness e equal to the clearance which it is desired to obtain for the support member 14 is then disposed between this support member and the extraction roller 18. The assembly is held in this position by the spring 17 which pushes the support piece 14 against the calibrated wedge 19, itself bearing on the roller 18.
  • the adjustment of the stop 5 is carried out by loosening the screw 12, which has the effect of releasing the blocking of the stop 5 by the flange 11, the stop 5 then being brought by the spring 9 bearing on the member d 'support 14.
  • the screw 12 is then tightened to maintain the stop 5 in the position thus obtained and the calibrated shim 19 can be removed, the spring 17 then bringing the support member 14 into abutment against the roller 18, the member 14 thus having in this position a possible clearance equal to e.
