Definitions

  • the invention relates to a method and a device for transporting two flat objects.
  • the articles are in particular flexible items that are transported in a stacking tray.
  • a flat flexible mail sorting system transports each delivered mail and delivers them to one of several stackers.
  • the sorting system transports the items in a specific start direction. In order to eject those broadcasts that are to arrive in a specific stacker, these broadcasts are to be redirected from the start direction to a destination direction.
  • a method having the features of the preamble of claim 1 and an apparatus having the features of the preamble of claim 14 are made EP 0915051 B1 known. It describes how a shingled stream of overlapping broadcasts is generated. This shingled stream is diverted in the destination direction and transported into a stacking tray. Two consecutive shipments that are transported in the same stack tray overlap during transport in the destination direction.
  • the drive rollers of the other guide belts operate in a start-stop mode with short changeover times.
  • the other guide belts must be taut to transport the shipments safely.
  • the formation of the scale flow works as long as the shipments are sufficiently flat.
  • the end EP 0915051 B1 known method encounters limits when it is applied in a sorting system, which should be able to sort programs of very different thickness. Thick overlapping broadcasts can not do any more of the two be transported further guide belts. It would be technically impossible or at least uneconomical to movably support a drive roller of another guide belt, so that the distance between the two further guide belts becomes variable.
  • the invention has for its object to provide a method having the features of the preamble of claim 1 and an apparatus having the features of the preamble of claim 14, which avoids that one of the two objects during deflection or during transport in the destination direction in the guide device jammed.
  • two flat objects are first transported in succession in a starting direction. There is a gap between the objects during this transport.
  • the leading object is deflected in a target direction.
  • a guide device then transports the leading object in the target direction and then stops it.
  • the sum of the thicknesses of the two objects is determined. If the thickness sum is less than or equal to a predetermined thickness barrier, the following steps are carried out: As soon as the subsequent object reaches a certain position during transport in the start direction, the continuation of the transport of the preceding object is triggered. This triggering is done in such a way that the subsequent object impinges upon deflection on the leading object and during transport in the target direction overlaps the leading object at least temporarily.
  • the thickness sum is greater than the thickness barrier, so the continuation of the transport of the leading object is also triggered.
  • this triggering occurs in such a way that a gap remains between the leading and the following object. This gap is kept both during the deflection as well as the further transport in the target direction.
  • thick objects do not overlap. Just thicker objects, such. As letters, are usually more stable than thin, so that these thicker items need not be transported overlapping.
  • the invention makes it possible to redirect both thin and thick objects from the start direction to the target direction. It is not necessary to pre-sort or classify the objects to be transported and deflected according to their thickness. Furthermore, the invention saves the need to design the guide means so that it adapts to different thickness objects. Rather, the invention makes it possible to use the same guide device for different thicknesses of objects.
  • the differential treatment of thinner articles (the thickness sum less than or equal to the thickness barrier) and thicker articles is effected as follows: For thicker articles, the continuation of transport of the leading article is initiated earlier than for thinner articles.
  • the subsequent object does not "catch” the leading object, but rather causes a gap between the two objects during further transport in the target direction.
  • the subsequent object "caught” the leading, so that the two objects are transported overlapping in the target direction.
  • the method is preferably applied to a succession of successive objects, respectively a pair of contiguous objects. The subsequent object will after the deflection and the transport in the destination direction to the leading object, the others follow.
  • the objects to be transported are flat, flexible items.
  • the term "consignments" is understood in particular standard and large letters as well as postcards and flat consignments.
  • This sorting system transports each consignment and dispenses it into one of several stacking compartments.
  • the sorting system identifies the destination address of each item.
  • the stack in which a program is issued depends on the destination address.
  • the mailpieces are preferably stacked aligned on the leading and trailing edges. Shipments are stacked side by side with the surfaces.
  • the programs are to be stacked in the order in the stacking tray in which they pass through the guide belts and the other guide belts.
  • the sorting system initially transports the mail items in a specific start direction. In order to eject those broadcasts that are to arrive in a specific stacker, these broadcasts are to be redirected from the start direction to a destination direction. Between start direction and target direction is an acute angle ⁇ of z. B. 30 degrees. After being transported to the stacking tray, the mail items abut a wall of the stacking tray which is transverse to the destination direction. This aligns the leading edges of the programs.
  • a stacking spindle (a type of rotatable worm thread) moves the mail item after hitting the wall in a stacking direction perpendicular to the targeting direction.
  • a hook element or a rotary support pushes during the deflection temporarily between two consecutive programs. Nevertheless, it can happen that a subsequent shipment so bounces on the front of her shipment, that the leading or the subsequent shipment is kinked or twisted and damage to a shipment or a traffic jam occurs.
  • another method is used to avoid the risk of kinking or damage and yet achieve a high throughput: the formation of a shingled stream of overlapping shipments.
  • the consignments transport and sort consignments of different thicknesses. These shipments are not sorted according to their thicknesses, but depending on their destination addresses, eg. B. to allow a certain sequence of a mail delivery. Therefore, the thicknesses of successive programs - within certain limits - can vary as desired.
  • the invention saves the need to handle thicker shipments separately, in terms of time and would require effort. Rather, according to the invention, any desired sequence is diverted with thicker and thinner items.
  • Fig. 1 shows an arrangement for carrying out the invention. For clarity, a distance is shown between the drive rollers and the guide belts.
  • the arrangement comprises two rear endless guide belts 1, 2 seen in the start direction SR and two further endless guide belts 3, 4. These four endless guide belts are taut and made of an elastic material to transport flat items without slippage and without damage. Furthermore, the arrangement comprises a light barrier Li whose light beam is interrupted by transmissions when they are transported by the two guide belts 1,2 in the start direction SR. An in Fig. 1 The controller, not shown, receives measured values from the light barrier Li and controls the drive for the drive rollers of the further guide belts 3, 4.
  • a transverse wall 9 of a stacking tray is shown. This transverse wall 9 aligns several programs Se3, Se4.
  • a broadcast Se1 is first transported in the start direction S-R between the two rear endless guide belts 1, 2.
  • the program Se1 shoots past the two rear guide belts 1,2 and strikes the further tight endless guide belt 4. This redirects the program Se1 in the destination direction Z-R and carries them on.
  • the consignment Se1 is pulled between the two further guide belts 3, 4 and transported further. In this case, the program Se1 is bent around the rear drive roller 10 of the second further guide belt 3, in the target direction.
  • the shipment Se1 is stopped as soon as between the break point K (the center of the bent portion of the shipment Se1) and the trailing edge Hk1 of the shipment Se1 (as seen in the target direction ZR) is a predetermined distance s. This is achieved by stopping between the drive rollers of the further guide belts 3, 4.
  • the controlled stop causes the trailing edge Hk1 of a stopped shipment Se1 to always be in the same position.
  • the light barrier Li reports to the controller when the trailing edge Hk1 of the shipment Se1 has passed the light barrier Li. Because the transport speed is predetermined, it is clear when the preceding shipment Se1 the in Fig. 1 has reached shown position in which just the distance s occurs. After a predetermined period of time T0, the controller causes the further guide belts 3, 4 to stop the preceding transmission Se1. This period of time T0 begins at the moment when the trailing edge Hk1 of the preceding shipment Se1 has passed the light barrier Li1.
  • the rear portion which has the length s, only on the first further guide band 4.
  • the front portion is clamped between the two other guide bands 3, 4. Because the programs can have different lengths, the length of the front section also varies from length to length (eg, between 127 and 292 mm).
  • the stopped broadcast Se1 remains at least as long in the stopped and in Fig. 1 shown position until another shipment Se2 has passed the light barrier Li.
  • the stopped transmission Se1 functions as the preceding transmission, the further transmission Se2 as the subsequent transmission.
  • the thickness of each shipment is measured and buffered.
  • DE 4216146 C1 out DE 10319723 B3 and from US 2005280833 A1 Methods are known to measure the thickness of a moving flat transmission without contact. Other methods of thickness measurement can be used.
  • the thickness of each shipment is measured "at full speed", ie without slowing down the program.
  • the measured thicknesses d1, d2 of two successive transmissions Se1, Se2, which are both to be deflected in the destination direction ZR, are added together. This will calculate a thickness sum.
  • the thickness barrier DS can be adapted to different requirements, eg. As different consignment volume, adapt without having to modify other components of the requirement.
  • the two transmissions Se1, Se2 are deflected in such a way that they overlap each other during transport in the target direction.
  • the light barrier Li measures when a subsequent and not yet deflected program Se2 has passed the light barrier Li.
  • the triggering event for the continuation of the transport is that the leading edge Vk2 of Se2 passes through the light barrier Li.
  • the controller controls the drive of the further guide belts 3,4 so that the other guide belts work in a start-stop mode. At or after the triggering event, the controller restarts the drive. As a result, the further guide belts 3, 4 accelerate the preceding shipment Se 1 to a predetermined transport speed.
  • the following transmission Se2 is at the same time at the same transport speed initially in the start direction SR transported. It then hits with its front edge Vk2 on the moving leading shipment Se1, in such a way that between the point of impact and the trailing edge Hk1 of the leading consignment Se1 is a predetermined distance c.
  • the preceding transmission Se1 and the subsequent transmission Se2 describe the so-called bullet triangle.
  • the bullet triangle has an acute angle equal to the angle ⁇ between the start direction SR and the target direction ZR.
  • the leading and the following transmission overlap in a region of length c - measured in the target direction.
  • This overlapping area is delimited by the trailing edge Hk1 of the preceding shipment Se1 and the leading edge Vk2 of the subsequent shipment Se2.
  • the distance between trailing edge Hk1 and leading edge Vk2 is just c.
  • Fig. 2 shows the arrangement of Fig. 1 in the case of two thin transmissions at the moment in which the following transmission Se2 impinges on the preceding transmission Se1.
  • the leading consignment Se1 abuts against the taut further guide band 4, and between the start direction S-R and the target direction Z_R is an acute angle. Therefore, the moving leading broadcast Se1 redirects the subsequent broadcast Se2 to the destination direction Z-R.
  • the following transmission Se2 also gets between the two further guide belts 3, 4 and is transported in the destination direction Z-R.
  • a shingled stream of overlapping items is formed.
  • the shingled stream hits the wall of the stacking compartment.
  • the overlap prevents a collision between shipments when hitting the transverse wall 9 of the stacking tray.
  • This method is performed when the thickness sum is less than or equal to the thickness barrier.
  • the following transmission Se2 "catches" the preceding transmission Se1.
  • the further guide belts 3, 4 are started for this purpose so that the two programs Se1, Se2 overlap by c during transport through the two guide belts 3, 4.
  • the advantageous and technically feasible overlap is achieved as a scale flow.
  • a variation of the method just described is performed:
  • the further guide belts are not started immediately after the leading edge Vk2 of the subsequent transmission Se2 has reached the light barrier Li, but only after a predetermined time limit.
  • the measuring photocell Li is z. B. - seen in the start direction SR - compared to the embodiment in EP 0915051 B1 moved upriver.
  • the two further guide bands are started so early that the preceding program Se1 and the following program Se2 do not overlap. Rather, a gap arises between the two transmissions Se1, Se2 when the two further guide belts 3, 4 transport the two transmissions Se1, Se2 in the destination direction ZR. This gap can be as large as the gap in the previous transport in the start direction or differ from that gap.
  • Fig. 3 shows the arrangement of Fig. 1 in the case of two thick transmissions, at the moment when the subsequent transmission Se2 hits the preceding transmission Se1;
  • the shingled stream is formed to prevent the following:
  • the leading consignment Se1 abuts with its leading edge on the transverse wall 9 of the stacking tray.
  • the following consignment Se2 hits with its front edge Vk2 on the trailing edge of the adjacent leading consignment Se1.
  • This can in particular skew shipments. This can lead to buckling, jamming or even damage to shipments in the stacker. In particular, shipments with low inherent rigidity tend to buckling during stacking.
  • the invention provides that the overlap of two successive programs is not made only if the two programs are relatively thick. But these broadcasts are usually relatively stiff and do not buck. Especially such programs can therefore be transported without an overlap in the stacker and stacked there.
  • the sorting system comprises a controller which switches on and off the drive for rotating the further guide belts 3, 4.
  • the controller is connected to the light barrier Li and receives measurement signals from it. If the trailing edge Hk1 of the preceding consignment Se1 has passed the light barrier Li, the controller stops driving the further guide belts 3, 4. This stops the preceding consignment Se1 so that the distance s lies between its trailing edge and the break point.
  • the controller checks whether the thickness sum d1 + d2 is smaller or larger than the thickness barrier DS.
  • the controller preferably reads out the value d1 + d2 of the thickness sum from a data memory.
  • the controller switches on the drive of the further guide belts 3, 4 after the leading edge Vk2 has passed the light barrier Li.
  • the time between the time when the leading edge Vk2 has passed the photocell Li and the time at which the controller turns the drive on again depends on the thickness sum d1 + d2 and is set by the controller. If the thickness sum is less than or equal to the thickness barrier DS, the time span is equal to a predetermined first value T1. Otherwise, it is equal to a predetermined second value T2.
  • the controller automatically decides which value to apply depending on the thickness sum d1 + d2 and reads out the value to be used from a data memory.
  • the second value T2 is smaller than the first value T1. This causes the controller to do the following: With a large thickness sum d1 + d2, the drive is started earlier (after the lesser second period of time has elapsed), and the preceding shipment is transported earlier in the destination direction. The programs do not overlap. At a small thickness sum d1 + d2, the drive is started later (after the lapse of the larger first period of time), and the preceding shipment is later transported in the destination direction Z-R. The programs overlap.
  • a minimum gap L is specified. This minimum gap L should lie between two consecutive shipments, if these shipments are transported after redirecting in the destination direction. It is checked whether the leading consignment can be transported so far in the target direction that between the trailing edge of the leading consignment and the leading edge of the subsequent transmission, a gap of length L may arise.
