Definitions

  • the present invention relates to a method and a Device for lifting printed matter from one Stack according to the preamble of claim 1 or 2.
  • From DE-C-27 32 591 is a device for dismantling a stack known from printed matter of this type, in which the Suction head along a drive mechanism closed orbit is moved, the shape of a Hypocycloid is similar. At an upper turning point the suction head captures a corner of the lowest printed product in the stack and takes this corner to the next lower reversal point with.
  • the Drive mechanism that one with a drive motor with planetary gear connected at constant speed, is primarily there to move the suction head along the mentioned, having a certain shape trajectory to move. Although the speed of the Suction head during its movement along the trajectory, yet the occurring speed changes to the construction of the drive mechanism and thus bound the shape of the trajectory.
  • the present invention is based on the object a method and an apparatus of the aforementioned To create the kind that enables the Speed of the suction head during its movement along its path in wide limits and regardless of to vary the shape of the trajectory.
  • 1 denotes a stack that is formed by folded printed products 2.
  • the latter are in a by a feed conveyor 3 Shed formation S in which each Printed product 2 on the trailing Printed product rests.
  • the printed products 2 are from below pushed into the stack, as in EP-A-0 551 601 is explained in more detail.
  • a suction head shown only schematically 4 available the periodically in a manner known per se a vacuum source, not shown can be connected.
  • the suction head 4 is by means of a Drive mechanism 5 along a closed, pear-shaped orbit 6 moves.
  • the suction head 4 detects the top one Printed product 2 in the area of its folded edge 2a and lifts the captured printed product during the movement along section 6a of orbit 6 from stack 1 from.
  • the delivery point designated by 8 is by Switching off the negative pressure the entrained Printed product 2 delivered.
  • the Suction head 4 continues in the direction of rotation U. That in each case
  • the printed product 2 is delivered by a conveyor taken over, like that in the already mentioned EP-A-0 551 601 in more detail is described.
  • the suction head 4 is on attached to a support tube 9, which does not have a shown hose line with the already mentioned and switchable vacuum source is connected.
  • This Support tube 9 is on one arm 10a of a two-armed lever 10 attached, the other arm 10b opposite the arm 10a is angled.
  • the arm 10b forms the coupling one Crank arm 11 and is via a joint 12, the
  • the pivot pin is designated 12a, with a crank 13 connected.
  • the latter sits on one in the direction of the arrow
  • a rotating shaft 14, which in a bearing 15 is rotatably mounted.
  • the shaft 14, the longitudinal axis with 14 ' is designated by one with reference to Figures 3 and 4 driven drive device to be described.
  • the arm 10b of the lever 10 is over one Joint 16, whose pivot pin is designated 16a with a rocker 17 connected.
  • the latter is on a wave 18 attached, which is freely rotatable in a bearing 19 is.
  • the longitudinal axis of this shaft 18 is designated 18 '.
  • the rocker 17 is between the rotating crank 13 two end positions, dash-dotted in Figure 1 are shown and include an angle ⁇ , back and forth pivoted here.
  • the two end positions of the rocker 17 are by the positions of 16a 'and 16a' ' Designated pivot pin 16a.
  • the these end positions 16a 'and 16a '' are assigned positions of the pivot pin 12a designated 12a 'and 12a' '.
  • the suction head 4 As already mentioned by the Takeover point 7 along section 6a of the Orbit 6 moved up to delivery point 8. Between The take-over point 7 and delivery point 8 is the suction head 4 as already mentioned connected to the vacuum source and takes the top printed product 2 of the stack 1 with. After switching off the vacuum source and the thereby releasing the taken away Printed product 2, the suction head 4 is further in Moved in the direction of arrow U along orbit 6 until he got back to takeover point 7, where the next one Printed product 2 is detected.
  • This intermediate gear 20 which in the present case is designed as a crank gear and in particular as a revolving crank loop, has a drive member 21 which is driven by a drive motor 22, shown only schematically, at constant speed, ie at constant angular velocity ⁇ 1 .
  • the drive member 21 is mounted in a housing 24 via bearings 23 rotatable about its axis 21 '.
  • the longitudinal axis 25 'of the driving element 25 runs parallel to the axis of rotation 21' of the drive member 21 and is offset by the distance r from the latter. In other words, the driving element 25 is arranged eccentrically.
  • the driving element 25 is guided in a transverse groove 26 which is formed in an output member 27.
  • This Output member 27 is seated with a connecting part 27a the shaft 14 of the drive mechanism 5.
  • the axis of rotation 27 ' of the output member 27 is thus aligned with the axis of rotation 14 ' the shaft 14, however, is opposite the axis of rotation 21 'of the Drive member 21 offset by the amount e.
  • the intermediate gear 20 designed as a rotating crank loop now converts the constant drive speed of the motor 22 into a periodically changing drive speed for the drive mechanism 5.
  • 5 shows the course of the angular velocity ⁇ as a function of the time t by the curve 28. While the angular velocity ⁇ 1 at the input of the intermediate gear 20 is constant, the angular velocity ⁇ 2 with which the shaft 14 of the drive mechanism 5 is driven changes between a minimum value 28a and a maximum value 28b.
  • 29a and 29b indicate the positions of the intermediate gear 20 in which the minimum (position 29a) and the maximum (position 29b) of the angular velocity ⁇ 2 occur. It goes without saying that the positions of the positions 29a, 29b can be chosen as desired.
  • the speed profile generated by the intermediate gear 20 as described thus becomes the speed curve overlaid by the construction of the Drive mechanism 5 is determined.
  • This The speed overlap is now such that the Movement speed of the suction head 4 in the area of Takeover point 7, i.e. when immediately capturing subsequent lifting of a printed product 2, is minimal and then increases. This makes one flawless detection of the top one Secured printed product 2 of the stack 1 and on the other hand avoided that when lifting the captured Printed matter 2 the following Printed product 2 is entrained as a result of suction.
  • the suction head 4 is also attached to a support tube 30, which is only indicated schematically and which, as described with reference to FIGS. 1 and 2, is connected to a vacuum source via a hose line (not shown).
  • This support arm 30 is connected to a drive mechanism 31 which has a lever 32 with which the support tube 30 is fixedly connected.
  • This lever 32 is connected at both ends via joints 33 and 34 to other levers.
  • the joint 33 the lever 32 is connected to a lever 35 which is pivotally mounted in a bearing 36.
  • the lever 32 is connected to a two-armed lever 37, which is pivotably mounted in a bearing 38.
  • the two-armed lever 37 is connected at the other end via a further joint 39 to the coupling 40 of a crank drive, which is connected to a crank 42 via a joint 41.
  • the latter is seated on a shaft 43, which is only indicated schematically and which is connected to the output member 27 of the intermediate gear 20.
  • the crank 42 thus rotates at the angular velocity ⁇ 2 , the course of which is shown in FIG. 5, in the direction of the arrow B.
  • the connecting joint 41 between the crank 42 and the Accordingly, dome 40 runs along a circular path Orbit 44 around.
  • the lever 37 performs a pivoting movement around the axis of its bearing 38.
  • the two end positions of the Levers 37 are on the one hand with a solid line and on the other hand, shown with a dash-dotted line.
  • the two joints 34 and 39 of the lever 37 move thereby along the lanes 45 and 46 between points I and II back and forth.
  • the lever 35 swings with one solid line shown position in the dash-dotted position and back again, the hinge 33 along the path 47 between the Points I 'and II' moved back and forth.
  • the solution according to the invention can also be used for Use embodiments in which the Printed matter not as described above by be lifted off the top of the stack, but from below Stacks are withdrawn, such as e.g. in DE-C-27 32 591 is described.
