Definitions

  • the present invention relates to a unit for selecting and separating reams from a stack of sheets of paper or similar.
  • the present invention relates to a unit for selecting and separating reams from a stack of sheets, of the type comprising a television camera movable in a substantially vertical direction along the stack to acquire images of the sheets at a given scanning region; and a separating member which is inserted inside the stack to separate the reams successively from the stack.
  • the images acquired by the television camera are used by an electronic central control unit to control the movement of the separating member in said vertical direction, to count the number of sheets in a ream during said movement of the separating member, and to arrest the separating member at the last sheet in the ream to be removed.
  • the separating member is moved into contact with the stack at a given insertion region, and is inserted inside the stack to separate the ream from the stack.
  • Known units of the type described above have various drawbacks, mainly on account of the television camera and the separating member being so oriented with respect to each other that the scanning region, where the television camera acquires the sheet images used by the electronic central control unit to count the sheets as the separating member moves in the vertical direction, and the insertion region, where the separating member is inserted inside the stack, are distinct regions located a given distance apart.
  • the unit only operates correctly, i.e. the insertion region is only positioned correctly at the last sheet in the ream to be removed, when the sheets have a perfectly flat profile.
  • the separating member may be inserted inside the stack at a sheet other than the one counted as the last sheet in the ream at the scanning region, and so remove a ream comprising more or fewer than the correct number of sheets.
  • a unit for selecting and separating reams from a stack of sheets of paper or similar as claimed in Claim 1.
  • Number 1 in the accompanying drawings indicates as a whole a unit for selecting and separating reams 2 from a stack 3 of sheets 4 supported on a pallet 5 and comprising a number of sheets 4 stacked in a vertical direction 6.
  • Unit 1 comprises an optical image-acquisition device 7 positioned facing a front face 8 of stack 3, and in turn comprising a first slide (not shown) movable in direction 6; a second slide (not shown) connected in known manner to the first slide (not shown) to move linearly in a horizontal direction 9 crosswise to direction 6; and a television camera 10 mounted on the second slide (not shown), having an optical axis 11 parallel to direction 9, and for covering a given portion of face 8.
  • the portion of face 8 covered by television camera 10 can be varied to define, on face 8, a given scanning region 12 which can be illuminated by a light source 13.
  • direction 9 and, therefore, axis 11 form an angle a of other than 0° with a horizontal direction 14 perpendicular to face 8, which, unless otherwise stated, will be considered a flat face parallel to direction 6.
  • Unit 1 also comprises a separating device 15 for separating reams 2 from stack 3, and which in turn comprises a first slide (not shown) movable in direction 6; a second slide (not shown) connected in known manner to the first slide (not shown) to move linearly in direction 14; and a separating member 16 mounted on the second slide (not shown).
  • a separating device 15 for separating reams 2 from stack 3, and which in turn comprises a first slide (not shown) movable in direction 6; a second slide (not shown) connected in known manner to the first slide (not shown) to move linearly in direction 14; and a separating member 16 mounted on the second slide (not shown).
  • Member 16 is defined by a substantially flat, wedge-shaped blade 17 which is inserted inside stack 3 at a substantially spot-shaped insertion region 18 lying in scanning region 12 of television camera 10, and whose location on face 8 is indicated, when blade 17 is located a given distance from face 8, by a laser pointing device 19 integral with member 16 and for illuminating a portion of face 8 coincident with region 18.
  • television camera 10 is moved in direction 6 to acquire, within scanning region 12, the images of a number of sheets 4 normally approximating in excess the number of sheets 4 in a ream 2.
  • the images acquired by television camera 10 are used by an electronic central control unit 20 to control the movement of blade 17 and, therefore, of insertion region 18 in direction 6, to count sheets 4 as blade 17 moves in direction 6, and to arrest blade 17 in direction 6 once blade 17 is positioned at the last sheet 4 in the ream 2 to be selected and removed.
  • blade 17 is moved in direction 14 and inserted inside stack 3 at region 18 to separate the ream 2 considered from stack 3.
  • insertion region 18 is always located within the portion of face 8 covered by television camera 10. Consequently, when blade 17 is arrested in direction 6, insertion region 18 is always located correctly at the last sheet 4 in the ream 2 to be removed, regardless of the shape of sheets 4, i.e. regardless of whether the profile of sheets 4 is perfectly flat or undulated.
  • central control unit 20 also provides, as television camera 10 moves in direction 6, for continuously feedback-controlling the movement of television camera 10 in direction 9 in response to a signal from a distance sensor 21 integral with television camera 10.
  • Moving television camera 10 in direction 9 provides for maintaining a substantially constant distance, measured parallel to direction 9, between face 8 and television camera 10, and so enabling television camera 10 to acquire correct images of region 12, i.e. to correctly focus the images of region 12.
