Definitions

  • the invention relates to a device for positionally accurate feeding of flat sorting pieces to one Input device for a sorting conveyor.
  • Such a device is usually in one Sorting conveyor used for post automation, like a such as in the European patent application EP 827 786 A1.
  • this has Sorting conveyor via so-called bullet devices, the the flat sorting pieces in pockets of a revolving Shoot in the conveyor. These bags become the flat ones Sort pieces on the assigned to them physical destinations and can are subsequently brought to their destination.
  • Such direct mail items are usually, but also other flat sorting pieces in horizontally stored stacks placed in the feeder mentioned at the beginning and have to be subtracted individually from these stacks, what to and technically also very much in itself is challenging task. So that these flatten themselves out in the Usually horizontal sorting pieces but with a Bullet device in the rotating sorting conveyor can be fed in, it is necessary to this Set up sorting pieces vertically. This setting up does however, it in turn required the sorting pieces previously positioned very precisely on the device for Setting up the sorting pieces can be introduced. in this connection aggravates the fact that the little are rigid and little homogeneous sorting pieces, e.g. the above Direct mail, particularly difficult to handle and therefore usually cannot be fed automatically, but manually from an entry place on the Feeder must be positioned, what a represents a significant cost factor.
  • the invention is therefore based on the object Device for the precise feeding of flat Sort pieces to an input device for one Specify sorting conveyor that makes it possible in particular also the above-mentioned particularly problematic Sorting pieces are sufficiently precise for further processing supply.
  • a comparatively stable edge for example the folded edge, when the sorting piece is later placed underneath can be arranged.
  • the sorting pieces that have a preferred edge, in stacks in the take-off unit can be stored and with the preferred edge at the front Are conveyable.
  • the trigger unit comprises a drum-like, rotatable unit which has suction cups and a transport securing element, an attack on one of the drums with the suction cups closest sorting piece is provided and then an edge with the transport securing element, in particular the preferred edge that engages with the suction cups standing sorting piece can be brought into engagement.
  • the suction cups can be placed at the bottom of the stack Aspirate sorting piece near the edge and because of the Circular path of the drum from the sorting pieces above separate. Then this affects the circular movement controlled transport securing element, for example a that Sorting piece with the edge pressing against a counter bearing Lever, the sorting piece, which is now out of the stack pulled out and on the circular path in a suitable position is promoted.
  • Sorting piece is particularly useful if to store the Sorting piece on the conveyor line according to each predeterminable Rotational angular distance the vacuum of the suction cups again degradable and the transport securing element from the edge is removable.
  • the sorting piece is thus freely conveyable the conveyor line, which does not necessarily mean that the sorting piece is placed in a horizontal position because the circular movement of the drum-like unit too also allows other locations.
  • the predetermined funding location through one of the conveyor line assigned light barrier and / or by one of the Re presents the contact distance associated contact sensor his. Additionally or alternatively, the predefined one Funding location at the same time or alternatively also by the end of the Conveyor line to be represented.
  • a mechanically particularly reliable and simple to operate constructed feed unit results when the feed unit a telescopic unit with a movable carriage comprises, the sled with reaching the Extends sorting piece at the specified location, and where the defined feed the predetermined extension path equivalent.
  • This can extend and that subsequent retraction by electric motor, but for example be pneumatically activated. According to the control of this Activation elements can therefore be the pull-out path within appropriate limits are changed so that the pull-out route can be quite shorter than the length of the available standing pull-out means, e.g. an extension rail.
  • the slide of the telescopic unit is adjusted so that he has returned to his resting position before that ejected sorting piece following sorting piece predetermined funding location reached. It is the hint here allows the next sorting piece to do so above the retracting slide of the telescope unit the predetermined location can be transported. The only important thing is that the sled at least to that Time has returned to its rest position when that Sorting piece has reached the predetermined funding point and thus taking over the sorting piece on the sled imminent.
  • the telescope unit can the slide of the telescopic unit over a rotating Conveyor belt dispose, but not during the extension movement driven and driven during the insertion movement. So it is possible that the position of the sorting piece during the The extension movement relative to the slide remains unchanged and with a suitable movement during the insertion movement Drive of the conveyor belt depositing / transferring the Sorting piece on / to the input device is supported.
  • This backward insertion is relative to that Sorting piece equalized if a drive element for the Conveyor belt of the sled to the movement of the sled is coupled, with a free-wheel for the extension movement is provided and in the insertion movement At least the speed of the conveyor belt largely to the speed of the insertion movement is adjusted, but has an opposite sign.
  • the sorting piece particularly well from the conveyor line to be able to transfer the sled can both Conveyor path at least in the rest position of the Slide the telescopic unit as well as the slide comprise strip-shaped spaced conveyor belts, the strip-shaped conveyor belts of the conveyor line and the Telescopic extract are arranged alternately. On this creates a kind of transfer zone, so to speak at the same time (final) component of the conveyor line and the Is sled.
  • the sorting pieces can also be used in a suitable manner on the sledge - if not in the strict sense held - held. For this, the Sort pieces until reaching the predetermined funding location brought into engagement with a roller-mounted spring element which the sorting piece on the or the tapes of the Slides (lightly) press.
  • a different solution provides an embodiment of the Feed unit with a disc-like, rotating, not rotationally symmetrical conveying element in front, with its areas away from the axis on the sorting pieces, which the have reached the specified funding location, attacks and on this Way brings the feed to the input device until the areas closer to the axis attack the sorting piece to lose.
  • the sorts are as long pulled along by the conveying element, like those remote from the axis Attack areas on the sorting piece so that too in this way a defined feed can be achieved.
  • one can Height adjustment for the conveying element may be provided, so that the result is sorting pieces of different thickness nevertheless in engagement with the conveying element stay.
  • Swashplate may be provided due to its unbalance also only for one specific rotation Time in engagement with the sorting piece and thus ensures a defined feed of the sorting piece.
  • Figure 1 shows a schematic representation of a top view a first positioning device 2, with which flat in a horizontal stack 4 located sorting pieces 6 an input device 8 shown in sections be handed over exactly.
  • the precise handover is extremely important because the sorting pieces 6 then in the part of the Input device 8 from the horizontal to the vertical Location can be rotated and then not with one here shown bullet device in pockets one here sorting conveyor, also not shown be shot. Because of the above Process steps for sorting the sorting pieces 6 with one comparatively high sorting speed, it therefore makes sense that the sorting pieces 6 at any time must be very precisely manageable.
  • the flat sorting pieces 6 are in the embodiment in Format DIN A4 folded brochures in which one or several loose inserts are inserted.
  • the prospectus are not stapled, but only as a loose-leaf collection interlaid. It is easy to see that such Sorting pieces 6 are extremely difficult to handle because they are with the exception of the folded edge, which is hereinafter referred to as Preferred edge 14 is designated, otherwise none Attack points for a positionally automated Deliver transportation.
  • sorting pieces 6 are now in the stack 4 above one Separating drum 16 placed on a shelf 18.
  • the Separating stream is a component of one Trigger unit 15, which is within the dashed lines in Figure 2 removed enlarged for better understanding is shown.
  • the sorting item at the bottom 6a is then by means of suction cups 20 which are rotating on the Singling drum 16 are arranged, active from below sucked in and so from the stack 4 down first distracted.
  • the sucked-in sorting piece 6a its preferred edge 14 by means of a lever 22 on one at the Separating drum 16 arranged counter bearing 24 pressed so that the suctioned and with the lever 22nd pinched sorting piece 6a now the circular movement of the Singling drum 16 follows.
  • the telescope unit 30 is in the individual below Figures 7 and 8 described. At this point, Explanation just said so much that a movable sled 32 of the telescopic unit 30 at the speed of strip-shaped arranged last in the conveyor section 26 Extends belts 28 'of the conveyor section 26, i.e. so one Extending movement takes place when the preferred edge 14 of the Sorting piece 6a reaches a light barrier 34.
  • the Carriage 32 which is also strip-shaped Conveyor belt systems 38 has a defined Feed path and sets when entering, i.e.
  • the Sorting piece 6a on a conveyor belt 36 Input device 8 from where it is then in to the previous Direction of conveyance perpendicular direction in the input device 8 transported and rotated into the vertical. It is In addition, a rolling element 42 is provided, which is always on the conveyor belt 36 presses when the sorting piece 6a is filed, what to further preserve the exact Storage location for the sorting piece 6a contributes.
  • the sorting piece 6a on the conveyor belt 6 To put the sorting piece 6a on the conveyor belt 6 to be able to carry out precisely, i.e. in detail that the Preferred edge 14 always comes to rest in the same place, it is provided during the insertion movement that the backward movement of the carriage 32 by a Rolling of the conveyor belt systems 38 over that of the preferred edge 14 nearby leading edge 40 is equalized. It is with it a particular essence of the present invention that the relative position of the preferred edge 14 to the front edge 40 of the Carriage 32 remains unchanged during the extension movement and the front edge 40 relative to the insertion movement Preferred edge 14 retracts, but this is for the sorting piece 6a through the conveyor belt system rolling over the front edge 40 38 is equalized relatively. In this way the exact position of the sorting piece 6a also remains the insertion movement of the sled get what for Further promotion of the sorting piece 6a of great importance and an essential with the positioning device 2 intended goal is.
  • the third positioning device 12 can, according to FIGS. 5 and 6 clearly recognize that the sorting piece 6a here in perpendicularly falling direction on the slide 32 of the Telescope unit 30 is passed.
  • This variant enables the To simplify the input device 8 in that the Conveying section for rotating the sorting pieces 6a from the horizontal to vertical position has become obsolete.
  • the extension movement of the carriage 32 also changes with this variant basically nothing compared to the previous two variants.
  • FIGS. 7 and 8 A particularly preferred embodiment for the Telescope unit 30 show FIGS. 7 and 8 in schematic representation.
  • the telescopic unit 30 comprises a plurality of conveyor belt systems 38, each of which represents a conveyor belt strip. Based one of these conveyor belt systems 38 will function explained below.
  • Each conveyor belt system 38 has two pairs of rollers coupled by a closed band 38 ' 48, 50 with two rollers 48a and 48b or 50a and 50b includes. The relative position of the two rollers 48a and 48b or 50a and 50b within a pair of rollers 48, 50 fixed to each other.
  • the pair of rollers 48 is stationary on the Telescope unit 30 arranged and the other pair of rollers 50th is attached to the carriage 32 which the extension movement in the direction of an arrow 52 and the insertion movement in Direction of an arrow 54 takes place.
  • the rollers 48b and 50b each have a freewheel on, with the roller 48b counterclockwise and the roller 50b are locked clockwise. From this the result is that when the slide 32 is extended, the band 38 ' only via the rollers 48a and 48b of the stationary pair of rollers 48 rolls, with both rollers 48a and 48b clockwise roll. In this way, the sorting piece 6a changes when once it has reached the light barrier 34, its location no longer relative to the roller 50a during the extension movement, which is highly intended. Desirably different is this constellation in the insertion movement, in the the band 38 'only attached to the carriage 32 Rolls rolls 50a and 50b, the roll 50a in Run clockwise and roller 50b counterclockwise.
  • the sorting piece 6a "feels" during the insertion movement not the same at all, but keeps his with the Extension movement achieves end position as requested.
  • the Preferred edge 14 of the sorting piece 6a thus always comes exactly at the desired location on the input device 8 for Lie.
  • rollers 56 mounted spring plate 58 provided that Sorting piece 6a slightly on the extension movement Adhesive conveyor belt 38 'presses and at the Insertion movement over the sorting piece 6a - with no friction the sorting piece 6a - rolls back.
  • This area can therefore be used as a kind of transfer zone for the transition from the Conveyor path 26 to the telescope unit 30 can be viewed.
