Definitions

  • the present invention relates to a method for processing in particular for Preparation of batch delivered flat goods containing a variety of flat individual pieces, in particular of letters, comprising, wherein the individual pieces transported in a row and with an edge against a conveyor belt fitting be, with the individual pieces at least partially overlapping shingles abut one another and wherein the overlapping individual pieces by the following Process steps further separated (fanned).
  • the invention relates also a device for processing flat material, wherein the device a conveyor belt for transporting the upright on an edge flat goods , wherein the conveyor belt via a guide path on both sides of Leitpatenteden is limited, wherein the conveyor belt and the lead structures a Train transport channel.
  • the object of the present invention is now to provide a method for to prepare for the preparation of standing flat goods, which is technically simple and thus inexpensive to implement and the high Service life and processing speeds with further staff savings allows.
  • the basic idea of the method according to the invention lies ultimately in the flat material rising on the conveyor belt formed as underfloor belt continue to fan out during transport by double-sided loading and thus prepare for isolation. It is essential that first Slowing down the batch of letters arriving in the row, the shingles lie one above the other. According to the invention, this series of individual pieces, while it is driven from below through the lower conveyor belt, on the one hand by braked the braking device and on the other hand by the laterally arranged Taken drive device and accelerated to the individual deduction. By the negative acceleration on the one hand attacking the flat goods Brake device and the positive acceleration on the other hand to the Flat material attacking drive device become the shingle juxtaposed individual pieces fanned to another piece.
  • the conveyed by the conveyor belt flat material is doing especially before Reaching the single trigger with a flat side against the brake device guided. While the conveyor belt doing the letters of the middle layers of the Flat goods initially forwarded, which are connected to the braking device applying letters relative to the conveying speed of the conveyor belt braked. So shingles the individual pieces even further (“shingling") than it is up that was already the case. On the opposite side is the flat product According to the invention of a further drive device, in particular a driven sideband, so gripped that a gripped single piece for Single trigger is accelerated towards. This measure also contributes to another Fanning out. It is not necessary that both measures at the same time be exercised on the same section of the conveyor belt. You can also act on the letters in a row.
  • the device according to the invention in particular for carrying out the Method is appropriate, characterized by a side of the Conveyor belt arranged braking device, which thus part of one of mentioned leading structures and the one in the respective outer layer of the Flat good single item, which applies to the brake device, in Decelerates ratio to the speed of the conveyor belt.
  • the invention is the arranged on the other side of the conveyor belt Leit Modell of the drive device formed on the other outside of the Flat good single piece in relation to the speed of the Speeds conveyor belt.
  • the device in the parameters with regard to deceleration (negative acceleration) and / or (positive) Acceleration and / or the transport speed can be adjusted that the superimposed individual pieces fanned to another piece be, with the distance between the leading edges of the individual pieces and thus the dimension the fanning out after processing an adjustable minimum not below.
  • the mentioned parameters are adjusted so that the distance of the leading edges at the end of the processing is at least 5 cm.
  • the single piece located at the top of the row formed by the slab has a projection of at least 5 cm before the following single piece before it is deducted from the individual deduction from the series. This is a reliable one Single print possible, without causing multiple copies.
  • flat goods means a stack of flat objects (individual pieces), such as Letters are subsumed, with the individual pieces not overlapping one another lie, but - as in the case of the letters to be conveyed observe - is processed in a row offset from one another. On impact they are brought only with respect to their lower edge (orientation edge), on the they rest. The series can be more or less fanned out (shingles) be. As a “single piece” is a part of the amount “slab” called. If single pieces from the original pile are meant to be without Overlap to be transported to a neighbor, they are also considered as such designated.
  • the advantages of the invention are that both with the method and with the device at this "sensitive" point of transport and sorting of letters a high throughput while avoiding the known problems is guaranteed. At the same time, processing speeds of at least 3 to 4 m / sec and a throughput of up to 40,000 letters per hour, the device does not yet reach its limits with these settings.
  • the invention guarantees a special at this stage of processing Flexibility against different formats to be processed and Weights within the flat goods, especially within the usual Mixed mail, occur.
  • the Braking device formed by a wall with high friction, against the The located on one side of the flat items with a Site.
  • the wall of a plate member or a Be formed baffle whose surface is provided with a friction lining.
  • Friction lining may be a rubber-like material to which the letters hang stay. It should be noted that the larger the contact surface between Single piece and wall is, the greater is the braking force, with the Strength of the clamping, so the pressure on the wall, also an essential Role play.
  • Such a braking device is so far self-regulating, as in a thick pile of flat goods the outer unique pieces because of the higher Clamp further brakes, which, as needed in this case, to a stronger shingling and a larger buffering effect. Leaves the contact pressure with the Reduction of the stack after, so come the attached letters free and are transported in the direction of the individual deduction.
  • the braking device can be formed by a slow-moving sideband be whose surface has a high coefficient of friction. That's good for to guarantee the uniform wear of the surface and thus the To increase service life.
  • the braking effect can be supported by the fact that the wall about is mounted displaceably or pivotally perpendicular to the transport direction.
  • the displacement of the wall can be caused by appropriate means be, with a regulation on the amount of slab to be processed is to be provided. It is particularly simple and inexpensive, however, if the Movement is caused by a spring force in the direction of the Conveyor belt acts. Thus, the transport channel widens on arrival of a thick stack automatically and the contact pressure remains through the tracking the wall also during the reduction of the pile.
  • the strength of Spring force is advantageously adjustable. It is also beneficial if the Movement of the brake device in the direction of the conveyor belt by a stop is limited, so that the channel always has a certain cross section.
  • the Displacement of the wall can operate switches and / or sensors to be watched.
  • Singulation is particularly effective when the two-sided lead structures, in particular the sideband and the wall of the braking device, in one acute angles of a few degrees, in particular from 1 to 5 degrees to each other are arranged, wherein the guide structures in the transport direction funnel-shaped to merge.
  • the angle and the distance is advantageous adjustable.
  • the incoming slab is braked in a kind of funnel, whereby from the one side accelerates the letters of the drive belt become.
  • the two-sided guide structures are present single deduction up to the average expected strength of a few, especially less than three, have approached individual pieces. This is how it is Wedge effect reached at the end of the freewheeling track.
  • the method described in the context of this application, as well as the device can be particularly beneficial at a very early stage of processing of mail, which today is essentially manual labor is accomplished.
  • the letters come directly from the Mailbox in bags delivered, the contents of which is poured onto a conveyor belt.
  • From this mixed mail delivered as piled flat goods are first manual large format shipments sorted out.
  • the remaining shipments then have to be bundled and with respect to their longitudinal edges (orientation edges) packed in suitably formatted and standardized boxes.
  • the Letters that are properly combined in the boxes can then be further processed become.
  • the letters for the Preparing to bring in the box ready This work has been done by hand so far executed.
  • the device according to the invention is ready for stack-preparation heaps of flat goods delivered, in particular letter packs 1, shown before singling to individual letters.
  • the device has a Underfloor belt 2 ( Figure 2) as a conveyor belt, on which the on the sub-perspective the longitudinal edge (orientation edge) upstanding letters 1 in the direction of the arrow A (letter-line).
  • the conveyor belt 2 is over a guide path bounded on both sides by guide structures, wherein the Conveyor belt and the guide structures form a transport channel 3, in the the letters 1 are held against falling over.
  • the letter pack is 1 in the transport channel 3 to a series of shingles superimposed letters fanned.
  • the guide line ends up in a single deduction 4, each of which arrives at the head of the series incoming letter 5 and subtracts.
  • the arranged in this case on the right side lead structure is of a Braking device 6 is formed, the one on this side of the letter box. 1 located letter in relation to the speed of the conveyor belt 2 decelerating.
  • the braking device 6 has a wall with a high coefficient of friction, against which the letters located on the right side of the letter box 1 Create offset.
  • the wall 6 is held on a mounting plate 7, which is through running in slots 8 screws 9 in a direction of transport A inclined tip angle can be adjusted.
  • the holder of the wall 6 happens by means of two elements 10, which held displaceably in the direction of arrows B. are. These elements 10 are acted upon by springs 11 so that the Wall 6 can automatically adjust to different levels.
