Definitions

  • the present invention relates to a device for laying out, in particular, folded printed products according to the preamble of claim 1.
  • Such a device is known from EP-PS 0 059 873 or the corresponding US-PS 4,434,979.
  • This has a disk-shaped ejector wheel which is eccentrically mounted with respect to the impeller and which engages around the shaft of the impeller. Distributed around the circumference of the ejection wheel are twice as many stops as the paddle wheel has pockets. The ejection wheel is driven at half the speed of the paddle wheel, so that each pocket is assigned a stop for ejecting the printed products shot into the pockets.
  • a delivery conveyor is provided below the paddle wheel, which is driven at a speed which corresponds to the peripheral speed of the stops.
  • Each printed product shot into a pocket of the paddle wheel initially runs onto the relevant stop as a result of the relative speed between the stops and the pockets and is expelled from the pocket in the course of the further rotation of the paddle wheel and the ejection wheel and at a distance which is the distance between the stops corresponds, deposited in scale formation on the delivery conveyor.
  • a device for forming stacks from signature sheets ejected from a paddle wheel and conveying away these stacks in scale formation is known from EP-OS 0 179 992. This has a stationary stop, against which the signature sheets abut and are brought to a standstill, as seen in the direction of rotation of the impeller. The signature sheets ejected from the blades of the paddle wheel float in free fall onto a holding device or the signature sheets already placed thereon.
  • the holding device in each case holds back the bottom signature sheet of a stack against the frictional entrainment by the stack which has previously been formed and is to be transported away.
  • the Delivery conveyor and the paddle wheel are synchronized in such a way that the delivery conveyor in each case conveys away a stack as soon as it has the desired number of signature sheets.
  • the signature sheets are braked very strongly at the stop, which can damage them.
  • either one pocket of the paddle wheel can now be assigned a stop or two or more pockets can be assigned a common stop. If a stop acts on the printed product in a single pocket, the printed products are laid out individually, the distance between the leading edges of the printed products corresponding to the distance between the stops.
  • the number of ejection-effective stops it is now possible for the printed products arranged in two or more pockets to run onto a common stop and to be ejected from the paddle wheel lying one above the other. The desired formation is thus formed directly when the printed products are laid out without the aid of means provided outside the paddle wheel and the ejection arrangement.
  • the number of ejector-effective stops can be halved. This makes it possible to switch from laying out in a shed formation, in which each printed product is ejected individually from the paddle wheel, into a shed formation, in which two printed products are ejected together and one above the other, without changing the speed ratio between the paddle wheel and the ejection arrangement .
  • the ejection arrangement has two ejection wheels, each of which has the same number of stops. By aligning the stops of the two ejection wheels towards one another or by rotating the two stop wheels against one another by half a division of the stops, the number of stops which have an effect on ejection can be halved or doubled.
  • each printed product is braked in the same optimal manner by a first ejection wheel and the relevant bucket and guided to the stops of a second ejection wheel.
  • retrofitting of known devices for example a device according to EP-PS 0 059 873 or the corresponding US-PS 4,434,979, is possible without changing the paddle wheel or the ejection wheel.
  • a delivery conveyor according to claim 9 is provided below the paddle wheel.
  • the printed products are ejected from the paddle wheel and deposited on the delivery conveyor at essentially the same speed, seen in the conveying direction of the delivery conveyor, and placed on the delivery conveyor as they are transported away from the latter. There is therefore hardly any relative speed between the belt conveyor and the printed products to be placed on it, which leads to the formation of a particularly precise scale formation.
  • the device shown in FIGS. 1 and 2 has three paddle wheels 14 of a printing machine which are seated on a common shaft 10 in a rotationally fixed manner and are spaced apart in the direction of the axis 12 of the shaft 10.
  • the shaft 10 is freely rotatably mounted on stationary bearings 16 and driven in the direction of rotation U at the speed n1.
  • Each paddle wheel has ten pockets 18, which are open to the rear in the direction of arrow U and are separated from one another by blades 20 and are closed off in their leading region by a base 22.
  • the orbit of the trailing free ends 20 'of the blades 20 is indicated by dash-dotted lines and designated 20' '(Fig. 1).
  • An ejection arrangement 24 is provided in the area between each two paddle wheels 14. This has two ejection wheels 28, 30 driven in rotation around a dash-dot line of rotation 26 in the direction of arrow U.
  • the speed n2 of the ejection wheels 28, 30 is half the speed n1 of the paddle wheels 14.
  • the ejection wheels 28, 30 are disc-shaped, freely rotatably mounted on a common bearing arrangement 32 and encompass the shaft 10. The bearing arrangement 32 is further down in the 3 explained in more detail.
  • the two ejection wheels 28, 30 are of the same size and are sawtooth-shaped on their circumference.
  • the trailing flanks seen in the direction of rotation U form stops 34 for the printed products 36 shot into the pockets 18 for ejecting them from the paddle wheel 14.
  • Each ejection wheel 28, 30 has ten stops 34 evenly distributed on the circumference, the two ejection wheels 28, 30 are rotated by half a division of the stops 34 against each other.
  • the ejection arrangement 24 thus has twenty stops 34.
  • the flat flanks 38 leading in the direction of the arrow U have a kink 40 in their central region, the respective leading flank part 38 ', seen in the radial direction, with the circular movement path 40' of the kink 40 indicated by dash-dotted lines forming a larger angle than the trailing flank part 38 ''.
  • Both ejection wheels 28, 30 have two slot-shaped passages 42 diametrically opposite one another, running centrally to the axis of rotation 26.
  • a bolt-shaped fastening element 44 for releasably clamping the two ejection wheels 28, 30 runs through the corresponding passages 42 of both ejection wheels 28, 30.
  • the fastening element 44 is, for example, a screw-nut connection.

  • the distance between two stops 34 is indicated in FIG. 1 by the double arrow A and the distance between the folds 36 'of the printed products 36 laid out in scale formation S is denoted by A'. Since the speeds v1 and v2 are the same, the distance A corresponds to the distance A '.
  • FIG. 3 shows the bearing arrangement 32 for the two ejection wheels 28, 30 enlarged in a section along the line III-III of FIG. 1.
  • the paddle wheel 14 and the pinion 46 are seated on the shaft 10 in a rotationally fixed manner.

  • the ejector wheel 30 adjacent to the pinion 46 has on the side facing the pinion 46 has a round recess 54 which is central to the axis of rotation 26 and has internal teeth 56. This meshes with a corresponding toothing of pinion 46.
  • Fastening element 44 which is only indicated by dash-dotted lines in this figure, transmits the rotational movement of ejection wheel 30 to ejection wheel 28.
  • the reduction between pinion 36 and ejection wheels 28, 30 is designed such that the two ejection wheels 28, 30 are driven at half the speed with respect to shaft 10.
  • the two ejection wheels 28, 30 can be rotated relative to one another by half a tooth pitch of an ejection wheel 28 or 30.
  • the stops 34 of the two ejection wheels 28, 30 are aligned with one another.
  • the ejection arrangement 24 has only ten ejection-effective stops 34. All parts shown in these two figures correspond to the parts described above and shown in FIGS. 1 to 3. They are therefore only mentioned again to the extent that this is necessary for an understanding of FIGS. 4 and 5.

  • the two aligned ejection wheels 28, 30 rotate in the direction of arrow U around the schematically indicated axis of rotation 26 at the speed n2, which is half the speed n1 of the paddle wheel 14. This has the consequence that two pockets 18 each have a common stop 34 is assigned.
