Definitions

  • the invention relates to a device for changing the direction of movement of letters arriving in the direction of the long edges and similar rectangular items such that they emerge in the direction of the short edges.
  • the mail items are either in the direction of their long or in Transported towards their short edges.
  • the latter has the advantage that the desired distribution capacity (in letters per unit of time) can be achieved with a lower conveying speed, since then with the same gap between the letters, instead of the length, their height is decisive for the throughput.
  • the initially stacked letters are usually pulled (separated) from the stack in the direction of their long edges, a device is required in this case in which the position or the direction of movement of the letters is changed accordingly.
  • a device for changing the direction of movement of the mail items in the manner mentioned at the beginning relates, for example, to DE-AS 11 99 697.
  • the mail items moving in an upright conveying path in the direction of their long edges run there against a fixed stop and are then guided vertically upward, that is to say in the direction of their short edges.
  • the vertical conveying path contains fingers which are arranged at regular intervals and which grip the letter that has come in and is brought to a standstill on its lower longitudinal edge.
  • This device can therefore only be used for synchronous transport, i.e. the consignments must arrive at the same leading edge distances and in a certain time relationship to the position of the fingers.
  • the invention has for its object to provide a device of the type mentioned that allows any, "asynchronous" sequence of the programs, does not cause wear or noise problems and in the event that the lowest possible deceleration or acceleration forces are exerted on the programs running through , so that the operation of the device is relatively independent of the respective mechanical properties of the mail items (eg weight, rigidity and center of gravity) even at high conveying speeds.
  • the device according to the invention consists of the succession of the functional groups characterized in claim 1.
  • the mailpieces (letters) 1 to be processed are initially in the stack of a separator 2, by means of which they are individually pulled off to the right in the direction of their long edges and fed upright to a first conveyor line 10.
  • This runs in one first direction I and contains at its exit a first conveyor section 10a, in which the mail items are not carried rigidly in the usual manner, but are displaceable, and a conveyor device 10b in front of them.
  • the task of the conveyor 10b is to feed the mail items 1 in the first direction I such that their plane is essentially horizontal and that one of the long edges moves along a predetermined reference line 11 before entering the conveyor section 10a. Their design therefore depends on the original position in which the mail items enter the device.
  • the conveying device 10b contains a straightening section 3, in which the mail items entering on edge are aligned with their lower long edge at a reference plane 4, and a turning path 5, in which the mail items are recorded immovably and by a predetermined one, in the plane of the mail items and axis parallel to conveying direction I can be turned by 90 °. They are then such that their original lower edge now moves along the reference line 11.
  • the turning section 5 is also known in various forms. In FIG. 1, it consists of a first endless belt 6, which is guided around a vertical roller 7 and a horizontal roller 8, and an endless belt 6 ′, which is adjacent to the former, which is guided around a vertical roller 7 ′ and one below the roller 8 lying further horizontal roll is guided.
  • the first conveyor section 10a is explained below with reference to FIGS. 2 to 4. This is followed by a first deflection device 20 with conveying means, which detects the mail items 1 at the front edge and laterally lead away from the first conveying section with parallel displacement in a second direction II, which includes an acute angle ⁇ ⁇ 45 ° with the first direction I.
  • a second conveyor line 30 runs, from which the mail items that are carried away are detected and the output of which forms a second conveyor section 30 a, in which the mail items are displaceably carried.
  • the device according to the invention contains a second deflection device 40 with conveying means, which detects the mail items at the leading long edge and laterally lead away from the second conveying section 30a with parallel displacement according to FIG. 7 in a third direction III, which is at an angle ⁇ of 1 with the first direction I. essentially includes 90 0 - which achieves the desired change in the direction of movement of the mail items.
  • FIG. 1 shows, in a further embodiment of the invention, a third conveyor section 50 ', a delay device 60 and a conveyor device 70, the purpose of which is explained below.
  • FIGS. 2, 7 and 8 show a number of mail items 1 in positions which are characteristic of the mode of operation of the device, a small and a large size mail item being shown as if the mail items were transparent.
  • Figure 4 shows a modification in which the belt 15 'is guided with the aid of deflection rollers 17 and 18 and the roller 14' so that it runs parallel to the conveyor belt 13 at a short distance. Although there is generally no contact between the belt 15 'and the mail items, this belt also increases the security of entrainment in the conveying direction I by generating or maintaining a corresponding air flow. In the embodiment according to FIGS. 2 and 3, it may be expedient to attach a guide surface 19 over the uncovered end of the conveyor belt 13.
  • the first deflection device 20 contains a plurality of driven conveyor rollers which interact in pairs and are aligned in accordance with a second conveying direction II. At least two pairs of conveyor rollers 21 and 22 are arranged in the conveying path of the mail items 1 in such a way that they essentially simultaneously detect the front edge of the mail item being brought up. In addition, at least one further pair of conveyor rollers 23 are arranged for engagement on the long edge so that their detection area (i.e. the line on which the rollers touch) is at a small lateral distance d from the reference line 11. If the formats of the mailpieces to be processed are very different, the pairs of conveyor rollers mentioned can be supplemented by further pairs, of which the roller 24 or a further roller are shown in FIG. 2 or 3 with dashed lines.
  • the front edge of the consignment 1 does not run against a fixed stop, but instead moves in the conveying direction I within the first conveying section 10a into the detection area of the two pairs of conveying rollers 21 and 22, the peripheral speed of which second direction II in any case has a significant speed component in the first direction I.
  • this conveying speed in such a way that the said speed component is equal to the original conveying speed in the first direction I.
  • the conveying speed of the first deflection device 20 as well as that of the second deflection device 40 are selected empirically in such a way that overall an optimal operating behavior results.
  • the consignment 1 is forcibly moved out of the conveyor section 10a and laterally with a parallel displacement in the direction II. Shortly thereafter, the originally lower long edge also comes into the detection area of the conveyor rollers 23 (or 23 and 24), which support the forwarding of the mail item into the second conveyor line 30.
  • the conveyor section 30 contains a conveyor belt 33 guided around rollers 31 and 32 and a belt 37 guided above it by means of rollers 34, 35 and 36.
  • the latter rollers are arranged such that the incoming mail items initially in the area of the roller 35 are gripped relatively rigidly, while they are displaceably carried in the region of the outlet forming the second conveyor section 30a.
  • the second deflection device 40 consists of three pairs of conveyor rollers 41, 42 and 43 which are arranged such that their detection area (ie the connecting straight line of their contact lines) runs essentially parallel to the reference line 11. As soon as the consignment 1 with its leading long edge comes into this detection area, it is laterally pulled away from the second conveying section 30a with parallel displacement in the third direction III by the aforementioned conveying rollers.
  • FIG. 2 shows a third conveyor section 50, which also continues in the third direction III in continuation of the path of the mail items carried away by the deflection device 40 and, according to FIG. 6, consists of two conveyor belts 53 and 54 guided around rollers 51 and 52. These conveyor belts are guided with the aid of a support roller 55 in such a way that the consignments fed are rigidly recorded and also continued.
  • the described two-way deflection of the mail items is generally sufficient to solve the task at hand, it can be advantageous in particularly unfavorable operating conditions - in particular with regard to the nature of the mail items - between the second conveying section 30 a and the second deflection device 40 according to FIG. 8 to insert a further deflection device 20a, with conveying means (such as, in particular, pairs of conveying rollers) which capture the mail items at the approaching long edge and laterally move them out of the second conveying section with parallel displacement in a direction IIa which lies between the directions II and III.
  • the direction IIa thus includes an angle r with the original conveying direction I, for which the relationship ⁇ ⁇ ⁇ p applies.
  • Another deflection section would then follow the deflection device 20a, in which the mail items are carried displaceably in the direction IIa.
  • a stop surface 45 in the region of the second deflection device 40 or further deflection device 20a. It is arranged at the point where the short front edge of the mail items 1 is when its long edge comes into the detection area of the conveyor roller pairs 41 to 43 or other conveying means that lead away to the side. This stop may prevent particularly heavy mail items or those with an unfavorable position of the center of gravity from reaching an undesired position due to inertial forces. In a further embodiment, it is possible to design this stop surface as a conveyor belt 48 guided around rollers 46 and 47.
  • an additional alignment of the items carried away under parallel displacement can also be achieved within the scope of the invention by the fact that in the second deflection device 40 the peripheral speed of the conveyor roller pairs 41 to 43 is lower than the component related to the third direction III the conveying speed in the second conveying direction II. The same lower conveying speed then exists in the third conveying section 50 which follows in accordance with FIGS. 2 and 6.
  • the conveyor rollers 21 to 24, 41 to 43 and 61 to 63 of the deflection devices 20, 20a and 40 or the deceleration device 60 must have a surface with a high coefficient of friction and that they can adapt to different letter thicknesses in a known manner .
  • the latter can be achieved, for example, in that the shaft of the respective lower roller of a pair of rollers is rigid and the shaft of the upper roller is mounted on a rocker. It may also be sufficient if the upper rollers are provided with a thick, elastic covering when they are firmly supported.
  • the respective lower rollers can be mounted on a common shaft and the upper rollers individually on rockers or - if they have a thick elastic covering - also on a common shaft.
  • the aforementioned rollers are generally driven in such a way that the rollers belonging to one and the same deflection device have the same circumferential speed, it would also be possible within the scope of the invention, for example the roller pairs 21 to 24 of the first deflection device 20, to adapt to specific working conditions with coordinated, slightly different peripheral speeds.
