In the letter distribution technology, the individual items are "set up" before the stamping process, d. H. uniformly arranged with regard to the location of their postage stamps. In automated letter distribution technology this process of dividing up machines is taken over, the task of which is to put all shipments in to bring such a situation that, for example, with the mark at the bottom in front of a subsequent one Reach stamp device. The prerequisite is that all items have the stamp in their right hand upper corner wear.

The invention relates to a conveying device for achieving a uniform position of letters or similar, preferably flat, on one of two opposite edges, such as. B. the long edges, standing individual pieces, the position of the individual pieces of the conveyed goods by scanning devices determined and then the necessary in the conveying direction by position correction devices Corrective movement is caused, the conveyor device having two series-connected by comprises a single channel interconnected sections each containing two branches, and wherein a switch is located at the entrance of each section, which the conveyed goods according to the result its scanning optionally passes over one or the other branch of the section.

In this known conveyor device (German patent specification 1 078 949), one branch of each section contains a position correction device, the other branch of each section is designed as a detour channel. A turning device is used as the position correction device in the first section to be traversed by the mail items, whereas a rotating device is used in the second section. At the merging of the second section, that is to say at the exit of the device, all mail items have a uniform position with regard to their postage stamp. In this context, a turning device is a device which rotates the mail items about an axis lying in the plane of the mail items and in the conveying direction; a device which rotates the mail items about an axis running perpendicular to the plane of the mail items is referred to as a rotary device. However, there are limits to increasing the transit speed of shipments through the previously known rotating devices. In these occur at very high throughput speeds for items of oversized format or with a content whose focus is not in the middle of the item, during the rotation process such centrifugal forces that the friction of the rollers on the conveyor to achieve a

overcome the broadcasts and the latter are thrown out of the rotating device.

The object of the invention was now to provide an erection device to create in which the position correction devices in two sections, each with two Branches, with these sections connected by a single channel, and at which it is possible, avoiding the use of a rotating device, the throughput speed to increase the broadcasts significantly and at the same time a favorable arrangement of the scanning devices to reach.

The solution to this problem posed by the invention is based on the knowledge that it is possible is, items that occupy the four named positions with respect to their postage, with one rotation to bring one of the three spatial axes into the desired position. There are three position correction devices for these measures to disposal; Rotating device, turning device, reversing device. The latter rotates around an axis that is in the plane of the consignment and perpendicular to the conveyor of the consignment fertilize stands. All three facilities connected in series would be a continuous broadcast on After turning the exit three times, bring it back to the position that the shipment at the entrance of the first Had position correction device. As a result, the programs that do not have the Assume the desired position, be possible with a maximum of two position correction devices the desired Location. From these considerations it also follows that two position correction units

directions, connected in series, the same change cause the position of a shipment, as the third position correction device would do alone.

On the basis of what has been said so far, the mode of operation of the device described above (FIG. 1) is without further ado. In channel K ₁ , the mail items to be placed arrive upright in one of the four possible positions: either the stamp - viewed in the direction of conveyance - is on the left-hand side at the bottom front or back at the top, or it is on the right-hand side at the top front or the bottom at the back. The scanning device A ₁ , which scans the upper and lower edges of the mail items passing by, now determines whether or not there is a mark on the right-hand side of the mail item as seen in the conveying direction. If the scanning device A ₁ detects a mark on the shipment - above or below - so the switch W ₁ is controlled by the scanning device with the aid of electronic and mechanical aids (not shown) so that this shipment enters the detour channel K _s . If, on the other hand, the scanning device does not find a mark on the shipment, either because this mark is on the other side of the shipment or because the shipment has no mark at all, it controls the switch W ₁ with the aid of the means mentioned so that the relevant shipment is rotated by the turning device WE ₁ about its axis lying in the conveying direction, so that at the exit of the turning device the mark is on the right side of the rotated shipment in the conveying direction. In channel 7, the mail items coming from channels K ₂ and K _{3 are brought} together again and pass the further scanning device A ₂ located on its right-hand side at the end of this channel . This checks the mail items both for the presence of a mark on the upper or lower edge and for the absence of a mark and the presence of marks on the upper and lower edge. If the scanning device detects a mark at the upper edge of a shipment - the mark can only be located at the top in front - it controls the switch W _{2 with the aid of electronic and mechanical aids (not shown) in} such a way that the shipment in question enters channel J ^ ₅ and thus reaches the turning device WE ₂ and is rotated by the latter about an axis which lies in the plane of the mail item and in the conveying direction. If, on the other hand, the scanning device A ₂ detects a mark at the lower edge of a shipment - the mark can only be located at the bottom at the rear - it causes the switch PF ₂ to be reversed into the other position via the aids mentioned, so that this shipment is in the Channel K _{1 reached} . There it is rotated by the reversing device UE ₁ about an axis that lies in the plane of the mail item and perpendicular to its conveying direction. After the merging of the channels K ± and K ₅ , the mark is on the left side of the mail items in the conveying direction at the bottom front of all mail items. In this position, the mail items then pass through the stamp device Si. Having in the program, however, that no mark or a mark on the top and bottom causes the scanning device by appropriate control of the switch W ₂ by the auxiliaries mentioned that these broadcasts first into the channel ₅ and K. The failure container AB pass via the switch W ₃ , which is reversed at the same time, via the A 'failure channel K _{s TO.}

The embodiment of FIG. 2 only differs from that in FIG. 1. in that the turning device WE _{1 is} replaced by a reversing device UE ₂ . All other components 4 Fi g. 1 are unchanged in Fig. 2 and are infplgedes.sen also provided with the same reference numerals. The scanning devices and the switch controls could remain unchanged by using a reversing device UE ₂ instead of the turning device WE ₁ , since these two devices are to be regarded as completely equivalent for the scanning devices and the type of switch controls.
