Definitions

  • the invention relates to a device for merging (stacking) two different partial stacks of book pages.
  • This device is used to combine such partial stacks, each of which contains all the pages of a complete book block next to each other twice and the individual stack sheets are printed on both sides with two mutually opposite book pages and in each partial stack on one half of the stack sheets the pages of the book are continuously in in ascending order and on the other half the pages of the book in descending order.
  • every second partial stack is swiveled by 180 ° in itself about an axis standing at an angle of 90 ° to the sheet plane before being combined with the other tea stack.
  • the entire blocks are then cut in the middle, and you get two complete book blocks with the correct page order.
  • This known device is constructed in such a way that a tray is arranged for each sub-stack of similarly oriented stack sheets, also called signatures, and one of these conveyors is designed for rotating a sub-stack in its support plane by 180 ° and both conveyors in the merging area of the two sub-stacks are guided parallel to each other in the same conveying direction to the entire stack.
  • One conveyor device executes a 180 ° turn and is guided on one level, which is guided parallel and adjacent to the level of the other conveyor.
  • a plow-like guide is provided to combine the partial stacks.
  • the object of the invention is to provide such a device which performs the same work overall, but is of a simpler construction, in particular requires no two trays and no two conveying devices.
  • the device according to the invention should also be usable both for combining two partial stacks without twisting every second partial stack in itself, or else with such twisting, depending on the type of printed stacking sheets.
  • the space requirement of the device is to be reduced and the need for special types of folding apparatus, as are necessary in the known device, is to be avoided.
  • the conveyor which has the form of a conveyor chain provided with drivers, a rearrangement drum with a horizontal axis of rotation running transversely to the direction of movement of the conveyor chain is provided, which is driven synchronously with the running speed of the conveyor chain and which carries on its outer circumference a uniformly distributed plurality of tongs-like grippers for one partial stack each, of which each gripper grips a partial stack and, after rotation of the rearrangement drum by 360 °, sets it down next to the subsequent partial stack and releases it, and each gripper system during its rotation a gear in a speed ratio of 1: 1 to the axis of rotation of the rearrangement drum parallel axis is rotated such that the grippers always remain at the lowest point of the gripper system, projecting downwards.
  • gearbox that consists of a fixed sun gear, an intermediate gear rotating with each gripper system around the center line of the sun gear, and a planet gear fixed on the axis of rotation about which the gripper system is rotatably mounted in the rearrangement drum , wherein the number of teeth of the sun gear on the one hand and all planet gears on the other hand are the same for the purpose of achieving the desired speed ratio.
  • each gripper system of the rearrangement drum which in this case works as a reversing drum, is pivotally mounted on or in this drum and is pivoted in the upper region of its movement path about a vertical axis by 180 °.
  • each gripper system can be carried out by means of a friction wheel connected to it, which cooperates with a fixed friction rail, this friction rail being provided in the upper region of the movement path of each gripper system and the friction wheel being rotated together with the gripper system connected to it by running over this fixed friction rail.
  • the two positions of the gripper systems offset by 180 ° are expediently fixed by a catch sets. If such a device is now to be used in such a way that the partial stacks are not pivoted in themselves before they are combined, then this is possible in an extremely simple manner in that the friction rail can be moved into a position in which the friction wheels of the grippers don't come into contact with her.
  • such a friction gear can only extend over a relatively small circumferential angle, with the result that, particularly at higher operating speeds of the device, the pivoting of the partial stack by 180 ° about a vertical axis must be done quite quickly, and this can be too disturbing vibrations or flutter movements of the sub-blocks.
  • such a friction gear is exposed to certain wear and tear because it also contains transverse displacement movements perpendicular to the direction of frictional entrainment.
  • this friction gear can therefore also be replaced by a form-fitting motion transmission gear, for example in the form of a rack and pinion gear.
  • each gripper system is carried out by an output gear connected to it, which is provided with part-circular recesses (of more than 180 ° recess angle), which hold the cylindrical drive rods one on a shaft, which the gripper system with the Planetary gear connects, serve attached drive stick drive wheel, on the circumference of which drive sticks are attached distributed over 180%.
  • part-circular recesses of more than 180 ° recess angle
  • catches can be used to ensure that the two positions of the gripper systems offset by 180 ° are fixed by catches.
  • the drive shaft drive wheel is then expediently axially displaceably mounted on the shaft carrying this such that its drive sticks no longer come into engagement with the recesses of the drive wheel in the displacement position.
  • FIG. 1 shows a fixed sun gear 14, an intermediate gear 16 rotating together with one of the three gripper systems around the center line 15 and the planet gears 17 used to drive the gripper systems (not shown).
  • the number of teeth of the sun gear 14 and the planet gears 17 are the same, the suspension point A of the grippers always remains at the lowest point of the gripper systems.
  • the axes of rotation, parallel to the center line 15, of the gripper systems and thus of the planet gears 17 are denoted by 18.
  • a partial stack is picked up at point 1 during the rotary movement when it arrives there at the speed determined by the conveyor chain with its drivers. During the movement points 2, 3 and 4, the partial stack is still in the vertical position in which it was detected. When position 5 is reached, the partial stack begins to pivot about its vertical axis. This pivoting continues via point 6 to point 7, where a pivoting of 90 ° is then achieved.
  • the individual sheets of the first partial stack 19a shown below in the drawing are printed on one side with the book pages 1 and 24, on the other side with the pages 12 and 13. During transport between positions 1 and 5, the side printed with pages 1 and 24 faces forward.
  • FIG. 4 and 5 show that the rearrangement or turning drum consists of three firmly connected support arms 20, which are rotated together about the center line 15.
  • Each of the support arms 20 carries a gripper system, designated overall by 21.
  • a gripper system 21 is just about to grasp a partial stack 19a.
  • a gripper system is empty.
  • the third gripper system carries a partial stack 19a, which has already been rotated by 180 ° about a vertical axis, on its way to the release point.
  • the partial stack 19a in a gripper system 21 is rotated through 90 ° about its vertical axis.
  • Another gripper system is on the way to detecting a partial stack 19a.
  • a partial stack 19a is in the storage position, and another gripper system is on the way to picking up a partial stack.
  • each support arm 20 is rotatably mounted in the fixed frame 22 about the center line 15.
  • the fixed sun gear 14 is also attached to this frame.
  • the associated intermediate wheel 16 is rotatably mounted in each support arm 20.
  • a shaft 24, rotatable about a horizontal axis, is mounted in a tubular housing part 23 of the support arm 20 by means of two bearings.
  • a shaft 26 is rotatably supported about a vertical axis of rotation, which carries the actual grippers 27a and 27b.
  • This shaft also carries a friction wheel 28 which can be locked with the head 25 by a spring ball catch 29 in two rotational positions offset by 180 ° to one another.
  • the shaft 26 is not rotatably mounted directly in the head 25, but rather via a tubular sleeve 28 ⁇ integral with the friction wheel 28, in which the shaft 26 can be displaced by means of an adjusting screw 30 for adjustment to different heights of the partial stack 19a and can be locked in any position is.
  • the L-shaped guide track for the partial stacks 19a and 19b is designated.
  • the conveyor chain 32 runs in this guideway 31 and is provided with drivers 33 for the partial stacks 19a, 19b.
  • One gripper 27a is fixed, the other gripper 27b is movable for opening and closing.
  • the movable gripper 27b is connected to a pin 34 with head 35; the pin 34 is surrounded by a prestressed compression spring 36.
  • an angle lever 37 is provided which cooperates with the closing cam 38 in FIG. 4a in such a way that it releases the head 35 so that the compression spring 36 can press the gripper 27b against the partial stack 19a .
  • the opening cam 39 takes effect, as shown in FIG. 6a, this causes the angle lever 37 to grip behind the head 35 and to pull the pin 34 together with the gripper 27b firmly connected thereto against the force of the compression spring 36 and thus to open the gripper 27b.
  • each partial stack 19a about a vertical axis takes place through the interaction of the friction wheel 28 with a fixed friction rail 40 provided in the upper region of the orbit of the gripper systems 21, which, in the event that the partial stack 19a is deposited once without a 180 ° rotation the vertical axis is to take place, can be moved out of the movement path of the friction wheel 28 in a manner (not shown).
  • the fixed gripper 27a lies with its effective gripping surface, as can be seen in FIGS. 4a and in particular 6a, somewhat outside the vertical axis of rotation 26 of the gripper system in order to ensure that the part is put down without problems to enable stacks 19a next to the partial stack 19b located in the L-shaped guide 31.
  • the center shaft 15 of the support arms forming the drum is driven (see FIG. 4a) via a gear 41 fastened to the shaft 15 and a drive gear 42.
  • each gripper system 21 is rotated by 180 ° with its vertical shaft 26 with each rotation of the gripper system 21.
  • the two positions of the gripper system 21, which are offset by 180 ° relative to one another, can be precisely fixed and secured by (not shown) latches, as described above in connection with the friction gear.
