Definitions

  • the present invention relates to a sheet separation method which separates a sheet one by one from a bundle of sheets and a sheet separation mechanism and moreover, relates to a sheet feeder having such sheet separation mechanism.
  • a sheet separation mechanism which separates a sheet one by one from a bundle of sheets is known. These sheets are for example, postal matters such as postcards, letters and envelopes. Such sheet separation mechanism feeds a separated sheet to a processing step or a processing apparatus in a succeeding stage (i.e. next stage).
  • a sheet feeder shown in Fig. 18 includes a mounting table 101, a feeding conveyor 102 and a sheet separation mechanism 103.
  • the mounting table 101 is a table on which a bundle 10 of sheets 11 is placed in an upright position.
  • the feeding conveyor 102 conveys the bundle 10 of sheets 11 placed on the mounting table 101 toward a next stage.
  • the sheet separation mechanism 103 separates the sheet 11 one by one from the bundle 10 that has been conveyed to an end part of the feeding conveyor 102 and feeds the separated sheet 11 to a processing apparatus in the stage.
  • a posture of the bundle 10 of sheets 11 placed on the mounting table 101 is maintained in an upright position by a compartment 104 provided for the feeding conveyor 102.
  • the bundle 10 is conveyed toward the sheet separation mechanism 103 by the compartment 104 and a bottom belt 105 (i.e. in a direction of an arrow D11 in Fig.18 ) while keeping the upright posture.
  • the sheets 11 are suctioned in order, from a top sheet, by a vacuum suction chamber 107 via a suction belt 106 having a plurality of through-holes therein.
  • the suctioned sheet 11 is fed one by one in a predetermined conveying direction (in a direction of an arrow D12 in Fig. 18 ) according to a revolution of the suction belt 106.
  • the sheet separation mechanism 103 employing such suction belt, if the bundle 10 includes the sheets 11 which are attached firmly to each other, it is quite likely that the sheets 11 cannot be separated one by one. In such case, a bundle including two or more sheets 11 is fed to a processing apparatus in a next stage. For example, when the sheets 11 whose surface is vinyl-coated are stacked, the sheets 11 are firmly adhered to each other. In the above mentioned related art, since sheets cannot be properly separated through a suction/conveying operation of the suction belt 106, a plurality of sheets are simultaneously fed to a next stage.
  • the sheet separation mechanism includes a suction/pulling unit (i.e. capture unit), a separation unit (i.e. detachment unit) and a conveying unit.
  • the suction/pulling unit sucks and pulls an edge part of a sheet apart from a bundle of sheets using a movable suction head (i.e. sucker).
  • the separation unit separates a sheet whose edge part has been palled apart from the bundle.
  • the conveying unit conveys the sheet separated from the bundle toward a processing unit in a next stage. Since such sheet separation mechanism suctions an edge part of a sheet to pull the sheet apart from the bundle, the sheet, separation mechanism has a good performance for separating for a sheet compared with a sheet separation mechanism employing a suction belt.
  • EP-A-0 368 166 discloses an automatic strip and sheet loader system.
  • the system is used for successively feeding the topmost sheet of plural stacked sheets on command.
  • the system comprises magazine means for supporting plural stacked sheets, pickup head means mounted on said magazine means for lifting one end of said topmost sheet, separator means mounted on said magazine means to complete the separation of said topmost sheet from the remaining stacked sheets, drive roll means contacting said raised forward end of said topmost sheet and control system means for sequentially effecting their operation in response to demand and start control signals in accord with predetermined instructions and conditions.
  • a suction head of a sheet separation mechanism of such related art only moves linearly in a vertical direction to a surface of a sheet. Therefore, even when such suction head is used, a sheet is not separated from a bundle of sheets if edge parts of the sheets are strongly attached to each other.
  • An object of the present invention is to provide a sheet separation method, a sheet separation mechanism, and a sheet feeder in which a sheet can be certainly separated one by one even when stacked sheets are firmly contacted each other. This object is achieved with the features of the claims.
  • Fig. 1 is a plan view of a sheet feeder in an exemplary embodiment according to the present invention.
  • Fig. 2 is a front view of the sheet feeder in the exemplary embodiment according to the present invention.
  • a sheet feeder in the exemplary embodiment according to the present invention includes a sheet conveying mechanism 20 and a sheet separation mechanism 30.
  • the sheet conveying mechanism 20 conveys a bundle 10 of sheets 11, placed in an upright position, toward the sheet separation mechanism 30 (in a direction of an arrow D1 in Fig. 1 ).
  • the sheet separation mechanism 30 separates a sheet 11 one by one from the bundle 10 that is conveyed to an end part of the sheet conveying mechanism 20 and feeds the separated sheet 11 to a processing step or a processing apparatus (not shown) in a next stage (in a sheet feeding direction of an arrow D2 in Fig.1 ).

  • the sheet conveying mechanism 20 includes a mounting table 21, an end plate 22, an upright position maintaining/conveying unit 23 and a posture controlling/conveying unit 24.
  • the mounting table 21 is a table on which the bundle 10 of sheets 11 is placed in an upright position.
  • the end plate 22 moves in a direction of an arrow D1 and applies a pressure to the bundle 10 of sheets 11 to convey it, while keeping a posture of the bundle 10.
  • the upright position maintaining/conveying unit 23 conveys the bundle 10 in the direction of the arrow D1 while keeping the bundle 10 in an upright position.
  • the upright position maintaining/conveying unit 23 includes conveying belts 25 having teeth engaged with a bottom end of the sheet 11. Two conveying belts 25 are arranged side by side along the mounting table 21, and the belts 25 are driven at almost the same speed as that of the end plate 22. By the driving operation, the bundle 10 of sheets 11 is conveyed to the posture controlling/conveying unit 24 while maintaining an upright position.
  • the posture controlling/conveying unit 24 controls a posture of the bundle 10 which is conveyed to an end part of the upright position maintaining/conveying unit 23 while conveying the bundle 10 toward the sheet separation mechanism 30.
  • the posture controlling/conveying unit 24 includes two conveying belts 26 having teeth engaged with a bottom end of the sheet 11 and angle detection sensors 27 which detect a posture of the bundle 10 of the sheets 11-
  • the conveying belts 26 are arranged side by side so that the bundle 10 of the sheet 11 can be smoothly caught from the conveying belts 25.
  • the angle detection sensors 27 are arranged at both sides of a conveying path of the posture controlling/conveying unit 24 to detect an angle of the sheets 11.
  • a target angle in a posture control of the sheets 11 is 30 degrees
  • three angle detection sensors 27 are arranged on a straight line at an angle of 30 degrees with respect to a conveying direction (i.e. arrow direction D1) of the sheets 11 in Fig. 4 .
  • An angle detection of the sheets 11 is performed based on a detection timing of the angle detection sensors 27.
  • the bundle 10 of sheets 11 is placed on the conveying belts 25 of the mounting table 21 in an upright position as shown in Fig. 3 and Fig. 4 . Then, the end plate 22 and the conveying belts 25 convey the bundle 10 of sheets 11 toward a next stage (direction D1) while maintaining an upright position.
  • a conveyance of the bundle 10 of sheets 11 is taken over from the conveying belts 25 to the conveying belts 26 as shown in Fig. 5 and Fig. 6 .
  • the conveying belts 26 drive at a higher speed than the conveying belts 25 and the end plate 22, the bundle 10 is further conveyed while changing an angle of an upright position.
  • the angle of the bundle 10 is detected by the angle detection sensors 27 and a driving speed of the conveying belt 25 (or 26) is controlled by feedback-control.
  • the angle of the bundle 10 can be adjusted to an arbitrary value.
  • a driving speed of the conveying belt 25 (or 26) is feedback-controlled so that the target angle of the bundle 10 at an end part of the conveying belt 26 becomes 30 degrees.

Because of such movements of the suction head 34, an only suctioned edge part of the sheet 11 is bent, curled or curved. That is, the suctioned edge part of the sheet is pulled apart from the bundle 10 to generate a gap between the (first positioned) sheet 11 and the bundle 10 (i.e., the remaining sheets).

  • the conveying unit 33 includes a conveying roller 39. As mentioned below, the conveying roller 39 rotates on its axis while the sheet 11 is located between the conveying roller 39 and the separation, roller 36c.
