    The letters are placed in a pile (1') in the machine, the uppermost contacting the underside of a continuous belt (25). This top letter is picked up by the belt and moved horizontally between a pair of continuous belts (48, 49) placed next to the pile. The letters are conveyed for further processing. Underneath the belts are banks (71, 72, 73) of photoelectric cells. These are connected into a control unit (60) containing a logic circuit and controlling operation of the belts. As each leading or trailing edge of a letter obscures these cells, belts are energised to ensure correct spacing of the letters.

    Which device, including the control unit, is a top view. In the device (Fig. 1), the lower belt 2 passing through the rolls 3 and 4 is used as the substrate for the pack 1. The supports 5 serve for the flashing axes 6 and 7 of these rolls on the base plate 8. The engine 9 is driven. switch 1O. so that, if necessary, drives the lower belt in the direction of arrow A. The rear end of the bundle 1 abuts against the supporting sgen 11 provided with a handle 12, the wall 11 being fixed to the head 13 by means of a sleeve 14 with the possibility of turning and advancing parallel to the lower belt 2. The chain wheels 15 and 16, which are located on axles 6 and 7, pass a chain 17, which from above engages the protrusion of the supporting wall 11. When starting up the tube and the belt in its movement with the same speed, part of the supporting wall. If additional parcels are inserted in a pack, then the supporting wall ootvetstvenn moved away as a result of its pr1shodnimani by handle 12, whereby the tripping of the chain 1 in FIG. 1 also shows the continuation 18 of the base and the tip 19 of the sleeve 14. On the base plate 8 (FIGS. 1 and 2), the shaft 2O is mounted on which the roller 21 is mounted. The shaft 2O is also slouxit for swivel mounting of the rocker arm 22, which carries the axle 23 of the withdrawal roller 24. On the roller 21 and the withdrawal roller 24, there is a stretching element, a stretching taping element - a conveyor 25, the outer surface of which has a large coefficient of friction. The yoke 22 rests on the base plate 8 by means of the spring 26 in such a way that its position each time depends on the pressing force of the pack 1. The free end of the rocker arm acts on the lever 27 of the microswitch YL If the nakkmnny power of the pack 1 is small, the microswitch contact closes , as a result, it drives the motor 9. It promotes the tape 2, and the rollers in the compulsory order of the sub-score further. In addition, the rollers 21 and 24 are guide rollers for belt conveyors 28 and 29, which further envelop the guide rollers 30 and 31. Driven roller 32 is fixed on the base plate 8, roller 33 can be elastically fixed, for example, pivot arm. Behind the stop wall 34, the first measuring section 35 is located along the supply direction, and upon further passage, according to the measurement in the supply direction by a distance of 4 (Fig. 2), the second measuring section 36. According to the invention, these measuring sections are designed in such a way that their output signals serve as a measure for the lengths of these measuring sections traveled by the edge of the consignment. In the first exemplary embodiment (Fig. 1), both measuring sections 35 and 36 consist of seven consecutive photo cells, where each receiver is indicated by a corresponding high sign 37 and 38 and, respectively, 39 and 4O. In this form of execution, so-called diode cells can be optimally used as receivers of light. Corresponding light sources are designated respectively 41 and 42. Except -. In addition, there is a photo cell 43 with a source of light 44, which controls the pick-up area of the rollers 32 and 33. Mailings should be made in the delivery direction with the same clearance, i.e. when the distance 8 remains unchanged between the leading edge of the unit of departure and the trailing edge of the previously issued unit of departure. In the known separation devices of the named type, when the sending unit is extended from the pack to the standby position, then at least one more, the next unit of mail, which stops somewhere in the area of the pressing mechanism, moves out to the pickup area of the permanently operating rollers. Thanks to the invention, it is possible to push the dispensed units from this random position directly into the gripping area of the permanently working skinny rollers 32 and 33, so that they fall on the supply path, separated from the base edge of the previously issued mailing unit with a predetermined distance. This is possible with the use of measuring sections 35 and 36 and a correspondingly complete control unit 45 (Fig. 3). The control unit 45 is executed in such a way that the drive of the belt conveyor 25 is put into operation at that moment, as soon as the track segment on the second measuring section 36, traversed by the trailing edge of the previously sent unit of departure, becomes equal to the segment the length of which is extended by the added unit of mail on the first measuring section. 35. The principle of operation of the node 45 is that the comparison of the lengths of the path traversed by the named edges of one after another units of mailing is carried out by means of a logical connection of the output signals of the corresponding photo cells of both measuring sections 35 and 36. Seven elements are used for this And 46, which are individually designated as 47 and 48, inverter 49, element OR 50. Photo cells 37-40 and 43 output logical 1 as an output signal, if they are illuminated, and logical O, if they are darkened. Both inputs of elements And 47 and 48 are connected in series with the photo by cells 37 and 39 to 38 and 40, the inputs of the last element And 48 through inverter 49 are connected to the photo by cell 38 and directly with photo by cell 140. The outputs of elements And 46 are connected through the element OR 50. The next element is AND. 51; receives a signal from the photocell 43 and the element OR 50, and the element 52 receives a signal 1 from the element AND 51 and from the photo cell 37. Through the element 53 and through a power amplifier (not shown), this 1 is given as a control signal the brake clutch 54 until the second input of the element I 53 is prepared by the Operation signal supplied to the terminal 55, and the conveyor 25 is driven by the roller 24. The second example of execution (Fig. 4) differs from the first (Fig. 1) first of all by the fact that in this case the unit of departure must with edovat at a predetermined distance C on the leading edge of a previously sent insult of unity (and not on its trailing edge) along the feed path. Accordingly, the correspondingly located points of the measuring sections 56 and 57 are characterized by this segment C. That time, as in the first example of completion (Fig. 1-3), the covered sections of both measuring sections are marked by a certain number of successive sensitive elements, in the second embodiment (Fig. 4), measuring sections 56 and 57 are each formed by one single sensitive element whose output signal, in its amplitude value, serves as a measure for the performed Comparison of segments. These sensitive elements can be, in particular, photoelectric receivers, which are illuminated by sources 58 and 59 of light and whose output signals in accordance with the darkened one a ra sent by the segments depend on the illuminated surface. In accordance with this, the control node 45 of the separation node is designed in such a way that it sends an alignment signal for the excitement of the brake clutch 54 as soon as aNmrarrynHoe the output value of the U3tv epUTej Lbth section 56 is equalized with the amplitude value of the output signal of the measuring section 57. Otherwise, the printing of the operation of this executive example corresponds to the design of the operation of the example of the HQ implementation of FIG. 1-3. The principle of operation of the device after switching on is as follows. Assumed to be 1 m advanced by the conveyor .25 the first unit of the postal sender 1 just got into the capture area constantly acting on the rollers 32 and 33, then gala photo cell 43, as a result of which the excitation from the brake clutch -54 was removed due to the blocking element And 51 The conveyor drive then stops. Rollers 32 and 33 remove the postal unit from the area of the stopped conveyor 25, while the next unit of delivery, taken out of the pack simultaneously with the postal unit being considered, remains in the designated position under the action of the scraper so that it is pushed up to one of the photo of the cells of the first measuring section 35. Upon further advancement of the postal sender, on the way 28 and 29 of the submission, one after the other, the posterior edges of this mailing {1 37 and 38 of the first of r frontline plot 35, photo cell 43 and photo cell 39
    and 4O. As soon as one of the photo cells of section 35 becomes illuminated, and as a result, the second and measured) section 36, traversed by the trailing edge of the sending unit, becomes equal to the segment, the length of which was preceded by the previous sending unit on the first measuring section 35 (Fig. 2 ), one of the elements AND 46 outputs 1. As a result, through the element OR 50, through the photocell 43 prepared by the element And 51 and through the elements 52 and 53 and the brake clutch 54 a control signal is given. The conveyor drive 25 begins to function again, and the output unit shipped to the pick-up area of the rollers 32 and 33. As soon as its forward edge has darkened, the photo of the cell
    43, the initial connection is established again and the following cycles are repeated until the Operation signal is applied to terminal 55.
    In the event that, when outputting a single postal item, the sending unit was pushed out with it, the sending unit was pushed up to the photo of the cell 38 of the first measuring section 35, a light signal, usually fed to the last element And 48 by the next photocell of the measuring section 35 and, case, the missing one is
    : after the appearance of light in the photo cell 40, the element And 48 gives out.
    It may also be obtained so that when the first unit of departure is output, the next unit of delivery is not accidentally captured from the stove 1 and after that it moves to the first measuring section 35.
    The following execution of the sixth provides for such a type of assembly 45 that the conveyor is additionally activated if the output signal of the first measuring section 35 implies that the situation exists. In the example of execution on {) ig. 3, this is achieved in that the photo output of the cell 37 is directly connected to the element OR 52 in this way.
    that, regardless of the state of all the other photo cells, it gives 1, while the fato cell 37 is illuminated.
    If measuring sections 35 and 3 (Fig. 1 and 2) are formed by successive photo cells or similar photosensitive elements, the control node G can be executed in such a way that the comparison of both segments occurs when comparing the number of photo cells passed on the first and in the second measuring section.
    The use of the invention makes it possible to increase the sorting efficiency of postal items.
