    A known device is unreliable in operation. 20
    In order to increase the reliability of the device, the axis of installation of the cutter is located on the side opposite to the bevel of the cutter, and the means for pressing is located between two parallel 25 vertical planes, one of which passes through the axis of the cutter and the other through its bevel.
    Means for pressing contains a compression spring associated with the compartment.
    Means for pressing contains compression springs, one of which is connected with the cutter, and the other with the guide lever.
    In FIG. 1 shows a device, a General view; in FIG. 2-section aa in FIG. 1; in FIG. 3 (a, b, c, d) - cut-off in different operating positions, in FIG. 4-5 - cutter, options; in FIG. 6 - device, embodiment.
    A device for transporting flat objects contains a magazine 1 for flat objects guided along the guide plate 2.
    On one side of the conveyance path, separating conveyors 3 are arranged axially one with the other. Separating conveyors 3 are guided by rollers 4 and 5, seated on axles 6 and 7, located on the base 8. To drive the separating conveyors 3, the roller 4 has working surfaces 9 separated by annular grooves 10.
    On the path of the transportation line, the separated flat objects are transmitted by two contacting conveyors and 12, enveloping the rollers 13 and 14.
    To detain double flat objects on the transportation path, cutoffs 15 are installed.
    Each cutter 15 has a working surface with a bevel facing the magazine 1 for flat objects, and is mounted on an axis 16 parallel to 3 of the working surface of the separating conveyor 3.
    Each cutter 15 is located on the guide lever 17, sitting ... on the axis 18, mounted on the base-. ' and nii 8.
    The cutters 15 have friction linings 19 and holders 20 and are located at such a level (see, Fig. 2) that the end surfaces of the friction 15 linings 19 are opposite the plane between the two separating conveyors 3.
    The connection between the guide levers 17 and the cutter 15 is carried out. 20 is axis 16 located near the outlet region B of the cutoff.
    The cutter 15 has a means for pressing, located between two parallel vertical plane-35 th, one of which passes through the axis 16 of the cutter 15, and the other through its bevel.
    The clamping means comprises compression springs 21 and 22. The spring 21 is connected with the guide lever 17, and the spring 22 is connected to the cutter 15. The spring 22 acts near the inlet region E of the cutter 15.
    The spring 21 rests on a plate 23 mounted on a rack 24.
    On the contrary, each cutter 15 in the plane between the respective separating conveyors 3 is a thrust pin 25, which is a continuation of the lever 26 located 40 with the possibility of rotation on the axis 27, mounted on the base 8.
    Each lever 26 is coupled to a tension spring 28 suspended on a roller 29. A follower roller 30 is rotatably mounted on each lever 26.
    From the store 1 (Fig. 3, a) separating conveyor 3 is removed a flat object 31 ,. which captures the other ; goy flat object 32. The cutter 15 'is in the resting position, in which it is adjacent to the thrust pin 25 in the plane of the working surface 33 of the separating conveyor 3.
    When starting the forwarded flat pre-5 meta towards the inlet area E, the cutter 15 is shifted by the forwarded flat object 31 against the action of the pressing force of the spring 22 (Fig. 3, b). In this case, the cutter 60 15 rotates around the axis 16. Since the spring 22 acts between the cutter 15 and the guide lever 17, the force of the spring 21 acting through the axis 16 on the outlet region A of the compartment 15 is reduced accordingly by the ratio of the shoulders of the guide lever 17.
    The flat object 31 (Fig. 3c) has already reached the inlet region E of the cutter 15, due to which, in addition to the force of the spring 22, another force acts due to the friction between the 'flat object 31 and the cutter' 15 in the exhaust region A, a torque is generated about the axis 16.
    This additional clamp force in the inlet region E also acts in the operation phase (FIG. 3, d), in which in the outlet region A there is still only the trailing edge of the flat object 31. Only after it leaves the cutter 15, the torque relative to the axis 16 is weakened, as well as additional pressing force in the inlet region E, as a result of which the entrance to the zone E of the flat object 32 is not difficult.
    The switched force acting on the cutter 15 (Fig. 4) is generated by the force Fj applied to the guide lever 17, as well as by the second force F 2 applied to the cutter 15 near the inlet region E and thereby creates a torque relative to the axis 16 in the direction acting in the inlet area E of the shifting force. Since the force F 2 can be applied to the guide lever 17, it can also be created by means of a torsion spring acting between the cutter 15 and the guide lever 17.
    The forces F ^ and F ^ (Fig. 5) can be replaced by the resultant force Fj acting on the cutter 15 in the zone located between the axis 16 and the inlet region E of the cutter.
    The guide lever 17 (Fig. 6) of the shut-off device 15 is provided with a stop surface 34 cooperating with a stop 35 fixed on the base 8, whereby the resting position of the guide lever 17 and the axis 16 can be determined.
    To set the position of the cutter 15 relative to the guide lever 17 is a rod 36, coupled with the cutter 15 by means of the axis 37 and resting with the help of the installation nut 38 on the guide lever.

    [1]
    For stopping the double flat objects on the transport route, cutters 15 are installed. Each cutter 15 has a working surface with a skid facing the magazine 1 for flat objects and is mounted on an axis 16 parallel to the working surface of the separating trater 3. Each cutter 15 is located on guide lever 17, sitting on an axis 18 fixed to the base 8. The cutters 15 have friction linings 19 and holders 20 and are located at such a level (see FIG. 2) so that the end surfaces of the friction linings 19 are opposite the plane between the two separating conveyors 3. The connection between the guides of the levers 17 and the isolator 15 is made by an axis 16 located near the outlet region B of the isolator. The cutter 15 has a means for clamping, located between two parallel vertical planes, one of which passes through the axis 16 of the cutter 15, and the other through its bevel. The pressing means contains compression springs 21 and 22. The spring 21 is connected with the guide lever 17, and the spring 22 is connected with a cutter 15. The spring acts on 22 operates near the inlet region E of the shutter 15. The spring 21 rests on the plate 23 mounted on the stand 24. In the turn of each shutter 15 in the plane between the respective section The conveyors 3 have a stop finger 25, which is a continuation of the lever 26, which is rotatably mounted on an axis 27 mounted on the base 8. Each lever 26 is engaged with an extension spring 28 suspended on a shaft 29. On each lever 26 it is located opportunity w rotating follower roller 30. From the magazine 1 (Fig. 3a) severing conveyor 3 is removed plbski object 31 ,. which picks up another flat object 32. The cutter 1 is in a resting position, in which it lies against the stop finger 2 in the plane of the working surface 33 of the separating conveyor 3. When starting to send flat items towards the inlet region E, the cutter 15 is displaced by the sent flat subject 31 against the action of the force of the spring 22 (Fig. 3, b). The cut-off device 15 rotates around the axis 16. As the spring 22 acts between the cut-off device 15 and the guide lever 17, the force of the spring 21, acting on the axis 16 on the outlet region A of the body 15, is reduced by the ratio of the arms of the guide lever 17. The flat object 31 (Fig. 3, c) has already reached the inlet region E of the trimmer 15, due to which in addition to the force of the spring 22 there acts another force, due to the fact that by means of friction between the flat object 31 and the isolator 15 in the outlet region A you create with a torque about axis 16. This additional force of yrizhima in the inlet region E also acts in the work phase (FIG. 3, d), B of which only the rear edge of the flat object 31 is in the outlet region A. Only after it leaves the trimmer 15, the torque is weakened with respect to axis 16, as well as the additional pressing force TO of the inlet region E, as a result of which the entrance into the zone E of the flat object 32 does not impede. The repositioned force acting on the cutter 15 (Fig. 4) is formed by the force F; f applied to the guide lever 17, as well as the second force p2 applied to the cutter 15 near the inlet region E and thereby creating a torque about the axis 16 in the direction acting in the inlet region E permutation effort. Since force F can be applied to guide lever 17, it can also be created by means of a torsion spring acting between cutter 15 and turning the lever 17. The forces F and F (Fig. 5) can be replaced by the resultant force Fj acting on cutter 15 the area located between the axis 16 and the inlet region E of the trimmer. The guide lever 17 (Fig. 6) of the shutter 15 is provided with a stop surface 34 cooperating with a stop 35 fixed on the base 8, so that the position of the rest of the guide lever 17 and the axis 16 can be determined. To set the position of the shutter 15 relative to the guide lever 17 serves as a cable 36, coupled with a cut-off 15 by means of an axis 37 and an anchor with c by means of an adjusting nut 38 on a guide lever.
