    An apparatus for destacking a stack of flexible flat structures, especially unfolded or folded sheets or printed products, comprising a stack support composed of revolving driven rolls and contact rails disposed above the stack support for defining a stack support surface. A separation device is arranged below the stack support and revolvingly driven in cycle or rhythm with the arriving rolls in order to continuously downwardly remove an edge of the momentarily lowermost flat structure between the arriving rolls. A conveyor device engages below the stack support for the removal of the printed products which have arrived beneath the stack support. The stack support surface is arranged to be at an inclination or directed obliquely at one of its corners towards the direction of movement of the rolls. The separation device comprises a single pre-separation element and guide means in order to displace the separation element at the region of said corner of the stack support surface from the top towards the bottom to thereafter remove such in the revolving direction out of the region of the stack support surface. The conveyor device possesses an endless, continuously driven conveyor element.

    (54) DEVICE FOR DISASSEMBLY OF STOPS OF SHEET
    Materials with cones of separating rollers 3, Chain 7 is driven in arrow 8 by means of sprockets 9, Common shaft 10 carries chain sprocket 11, which is connected to the drive gear of the electric motor by means of chain 12. The guides of the chains 7 have an inclined section 13 located in front of the supporting bars 1. The supporting surface 5 of the foot 2 is located at an angle to the direction of movement of the separating rollers 3. The vacuum suction device 4 is mounted on one shoulder of the double-arm lever 14, the free end of which with a roller 15 is connected to the wings liS. At the same time, the 17 double-arm lever 14 has a rotating support that is eccentrically mounted on the movable gear 18 of the planetary mechanism. The gear 18 is in engagement with the gear wheel 19 and rotates with the carrier 20. As a result of the rotation of the carrier 20, the gear 18 rolls along the inner surface of the gear 19, which rotates in the direction of the arrow 21 relative to its own axis. The pivot bearing (dot) 17 moves along a path in the form of a hypocycloid 22 (cf. fig.9). ..-.: -. Accordingly, the trajectory of movement of the pivot bearing (point) 17 moves the vacuum suction 4 along the trajectories 23 (see FIG. 4), which is similar to hypocycloid 22 but has one elongated side due to it due to the linear passage of one arm of lever 14. The trajectory 23 of movement It has a section 2 that extends from the upper side of the support to the lower side of the foot 5 of the foot 2 and moves along the path of the foot 25 that goes out of the foot of the foot 5 of the foot 2. Therefore, the vacuum suction cup The dead position (see Fig. 4) enters the supporting surface 5, then, during its movement along section 24, falls onto the lower side of the supporting surface 5 of the foot 2 and then along its path 25 leaves the zone of the supporting surface of the foot 1 in lateral, dead position. Plot 26 of the movement trajectory returns the suction cup 4 again to its dead position. The vacuum suction device 4 is actuated in time with the rollers 3 moving past it in such a way that after the passage of one roller 3 enters the opening 27 between this roller and the next one (see figure 4) and then leaves in time to clear the way.

    :: shhhhhhh:. roller (see Fig.5). Then, the vacuum suction device 4 returns again to the next after the above mentioned roller in its upper dead position. The vacuum suction device 4 in its upper dead point is connected to the source of rarefaction, but is disconnected from it in its lower dead point. Consequently, the vacuum suction device 4 is active during the passage of the section 24 of its path of movement, and passive during the rest of the movement. In its upper dead position, the vacuum suction device 4 sucks the angle of the lowest part 28 of the foot 2 facing the direction of movement and when moving to the lower dead position t there is no captured angle from the upper side of the supporting surface 5 of the foot 2 through the opening. The next roller 29 (see Fig. 5) can now go to the bent corner of part 28 of the foot (see Fig. B). The vacuum suction device 4 is immediately disconnected from the source of discharge and continues to move along its path, and, moving away from the angle of part 28 of the foot that is held by the roller 29 in the bent position, again falls into the upper dead position to grab the corresponding angle of the lowest part now. 30 of the foot 2 and enter the angle into the opening between the roller 29 and the next roller 31. The roller 31 slides over the bent corner of part 30 of the foot, and the vacuum suction 4 continues to move along its path. During the movement, the rollers 29 and 31 (see FIG. 8) gradually disconnect parts 28 and 30 of the foot 2. In parallel, the base of the support bars 1 for the feet 2 is located receiving platform 32, located under the same an angle to the axis of the separating rollers 3. The sheets detached from the foot 2 fall onto the conveyor 32 and are transported in the direction of the arrow 33. The rollers 2 perform not only the carrier function, but also the separation function regardless of the weight of the foot

    2. The double-shouldered lever 14 has a console 34, through the opening 35 of which the vacuum suction device 4 is connected to the suction pipe 36 connected through the valve system 37 to the source of discharge. The drive behind the vacuum suction 4 is connected to the electric motor with the help of the shaft 39. The shaft 39 is placed in a stationary 40 and carries a disk 41, in which a shaft 42 is mounted eccentrically relative to the shaft 39, on which gear wheel 16 is fixedly mounted. The swivel bearing (point) P is fixed on the supporting arm 43 with support 44, which is ostrino lena eccentric with respect to shaft 42 so that the axis of the support pin 44 intersects the run-in circle of gear 18 and that the pin 44 moves along the hypocycloid trajectory 22, From this geometrically defined trajectory 22 of the support pin 44 with the help of a two-arm lever 14 and roller 15 scenes 16, the trajectory of movement of the vacuum suction device 4, claims 1. An apparatus for disassembling a stack of sheet materials comprising support plates for a foot, a means for separating sheets including a vacuum suction device and separating rollers with water located under the support bars, and receiving a conveyor, which means, in order to increase the productivity of the device, the means for separating the sheets are equipped with a planetary mechanism, a two-arm lever, eccentrically mounted on a moving gear plane tare mechanism, and a vacuum suction cup is mounted on one lever arm, and the second lever arm is mounted in the guides using a roller. 2, The device according to claim 1, wherein the drive of the separation rollers is designed as an endless chain with guides, kinematically connected with the planet carrier of the planetary mechanism. 3, The device according to claim 2, wherein the chain guides have an inclined section located in front of the support planks for the foot, with the suction suction mounted below the other inclined section and its inclination is directed in the direction opposite to the movement of the chain . 4. Device according to Claims 1 and 2, differing in that the base of the foot support plates is located at an angle to the axis. separating rollers. 5. A device according to Claim 1, characterized in that the receiving conveyor is arranged parallel to the base of the support bars at an angle to the OSI of the separating rollers. Sources of information taken into account in the expert examination 1. Accepted application of the Federal Republic of Germany No. 1137746; cl. 15 E 8/11, 1962.
