    1515443 Automatic control POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 8 July 1976 [15 July 1975] 28397/76 Heading G3N [Also in Division B8] As suckers 2 feed sheets 3 to rollers 4, 5 the positioning of pivotally-mounted moving rollers 5, in their respective lowermost positions imposed by cam 7, is varied to take account of variations in thickness of the sheets 3. Each roller 5 is carried by an arm 22 pivoted on an adjustable member 14, and the arm 22 and member 14 are mutually insulated, except through contact surfaces 30, 31. If the roller 5 contacts a sheet 3 ahead of the currently set position the contacts open, and motor 17 moves member 14 with respect to body 12 and shaft 10. Preferably the apparatus is set to adjust itself when a new pile 1 of sheets 3 is placed in position, and acts to lower the rollers 5 until they contact the sheets. Adjustment then follows until the rollers 5 are within a set tolerance of an optimum positioning with respect to the particular sheets 3, so that they are fed in exact synchronism with the suckers 2. Alternatively the apparatus may be made to adjust itself to skew presentation of the sheets.

    short shaft 10 thanks to the wedge 13 located between the nannvn.
    On the side of the shaft 10, the double-shouldered lever 12 is connected by means of a bolt 14 with an adjusting lever 15. A lever 15 is pivotally connected with the lever 17 by means of small pox 16.
    On the lever 17 is placed the pressure roller 5.
    On the two-arm lever 12 there is a means for adjusting the relative three-armed and double-arm levers, made in 1M1 servo drive 18, mounted on crown gang 19. located in the lever 15. By means of the smallpox of the 20 servomotor 18 in one NLP in the other direction, it is possible to change the distance between the bolts 22 and 23 in one way or another.
    A snStem management tool for rsgulnirovann relative to the position of the three-arm and two-arm levers includes an irn wavelength 5.
    The levers 15 and 17 together form the shoulder of the two shoulders and the electrical lever are insulated from each other with the nominal bushings 24 and two insulating cables 25 and 26 between the control lever and 15 and 27 and the control lever 17 with the support 28 and the electric lever. the insulated screw 29 has a compression spring 30. Due to this, the contact surface 31 of the lever 17 is arranged at a nanotube of the contact surface 32 of the lever 15.
    Through the contact surfaces 31 and 32, when they are in contact, the earth potential passes through the adjusting lever 15, and the lever 17 passes, and from there it is brought further by means of the electrical conductor 33 (i. Fig. 1). An electrical wire 33 leads to the control device 34 via an all-compatible relay 35 to the switching contact 36 for the transport process n to the switching contact 37 for the installation drive. The control device 34 is connected to the servomotor 18. In this case, the auxiliary relay 35 is designed so that the UHF of the contact surfaces 31 and 32 of the control device 34 is given an L-signal, since both the switches 36 and 37 are closed.
    Loaded from auxiliary relay 35, contact 38 is given two contacts 39 and 40, through which the level of the L-signal is fed to a self-stability switch 41 and converted into a short I-signal. A periodically occurring signal 42 and a tolerance-dependent signal 43, which are directed to the control device 34, are supplied from a single-speed register shaft (not shown) connected to the single-speed shaft.
    occurs depending on the deviation of the suction air on the conveyor belts. Due to a mountable discharge of Yun1, to her system 44, this signal is maintained for a relatively long time. The tolerance-dependent digital input entered after a short selectable tolerance time is also held at the same time as the signal 42 by means of the monostable deviation of system 45.
    Both monostable deflecting systems 44 and 45 are connected to a non- or 46 cell and an H 47 cell. To a 46 cell and to the one-stage exhaust system 41, there is also an H 48 cell. The signal from this cell affects another one that has a detachable rear 49, 49, and another 49. The duration of which is controlled by the impulse of the amplifier 50 n through it, the relay 51. By means of the contacts of the relay 52, the servomotor 18 controls. otpnte.PzPo nazran: epp his vpP1enp, prp which bolts 22 p 23 is driven in the drive pane 21. Odnovrepempo when triggered contacts of the relay 52 opens the pin 39 so that during the adjustment the feed L-spee is fixed by the common lever, so the L-spee drive has all the same, all the same, and the drive 39, so that L-spp is set up. I 47 cells are received by the operator; 1 53. The lynn string is fed to the following one. Monostable outage of the junction system 54 does not correspond to its control time with another amplifier, myyuity 55 and through the switch, which is controlled by the servo drive. li nrotnvo Vrana olozhnom direction; EPR. During this time, depending on the action of the contacts 57, the relay 56 opens the contact 40, so that during this phase the signal from the universal relay 35 is not transmitted further.
    } About the time of installation of the pressing rollers 5 to the new thickness of the material switch PU1PY contact 37 for setting drive n switching contact 36 for sheet transport process that (in the case of pressing roller 5 pressed on the beginning of sheet 2, contact surfaces 31 and 32 are opened, the bullet thermal does not pass to the all-rounder relay 35. In this case, from the auxiliary relay 35 to the control valve 34 is supplied /.- signal, i.e. contact 38 of the omnipotent relay is closed. Contacts 39 and 40 are also closed in this case, and L- signal reaches mono 41, and from there the short-term sigal is transmitted further to the AND 48 cell. If, at this time, the signal 42 and the signal 43, depending on the tolerance, are not fed to the non-OR cell 46, then it will be sent to the cell H 48, this relay 51 is controlled through a monostable deflection system 49 and a power amplifier 50. In this case, the mounting roller 5 is for some time on a sheet that is idle for
    through the contact of relay 52, rearrange the corresponding servomotor 18 by one step in the direction in which by means of the spindle 21 the bolt 23 and the adjusting lever 15 move away from the bolt 22. Due to this, the pressure roller 5 rises to a certain height and then seizes the next incoming sheet. During this step, the contact 39, which may be mechanically connected to the contact of the relay 52, opens, during which time the L-signal may be interrupted at the auxiliary relay by the contact 39.
    As soon as this step is finished, the contact of the relay 52 is returned to its original position, the contact 39 is closed again, therefore, when the pressure roller 5 is still outside the tolerance zone, the L-sigals from the auxiliary relay 35 are transformed further as described. This continues until the signals are received simultaneously with the signals 42. In this case, the NOT-OR 46 cell receives the signal through the monostable deflection system 44, and the signal does not reach the cell 48 from this 46 cell. At the same time, the outcome is from the monostable the deflection system 44, the signal is superimposed on the AND 47 cell. At the same time, the L-signal reaches the AND 47 cell simultaneously. As long as an L-signal appears inside the tolerance zone, the tolerance-dependent signal 43 enters the monostable deflection system 45. Moreover, the signal from cell 47 does not flow further. This happens when the pressure roller 5 grabs the next sheet too late. Then the L-signal instantly affects the AND 47 cell, in which the signal 42 still remains and the signal 43, depending on tolerance, is already supplied through the monostable deflecting system 47. In this case, the relay 56 is controlled through the signal amplifier 53, my stable deflecting system 54n power amplifier 55. Due to this, the relay contact 57 is activated, at the same time contact 40 is opened and the corresponding servomotor maintains a pulse to perform installation in the direction in which the screw spindle 21 through the bolt 23 5 t does not have an adjusting lever in the direction of the servomotor 18, as a result of which the pressure roller 5 is lowered. In the case of two-way adjustment is carried out automatically.
