Definitions

  • the invention relates to a device for collecting digitally, preferably sequentially printed, printed products fed from an axis, comprising a drive device, holding means for holding and releasing the printed products collected at the periphery of the collecting cylinder, and an actuator for controlling the holding means Actuating means cooperates with a stationary first curve, wherein the stationary first curve for releasing the holding means has a deviating curved portion which is at least approximately canceled by a second Kurvabites a second curve.
  • a device of this kind is known in the art from DE 103 15 443 A known.
  • printed products such as printed sheets for producing, for example, a newspaper on the circumference of the collecting cylinder can be collected.
  • the collected products can then be dispensed together and fed to a folder, for example.
  • the collection cylinder can also simultaneously as a folding cylinder be formed and have folding blades on its periphery.
  • this holding means for example puncturing needles, which are extendable with respect to the circumference of the collecting cylinder. Since the necessary movements of the holding means for collecting and delivering the printed matter are not the same for each revolution of the collecting cylinder, these movements can not be controlled with a single curve.
  • a rotating cover disc is therefore provided in addition to a stationary curve, which is scanned by the control lever.
  • the cover plate has two sections of different radius and is rotatable about the same axis as the collector cylinder.
  • the control lever has two mutually movable, each carrying a role arms. One of these rollers follows the contour of the cover disc. The control of the cover plate and the curve is relatively expensive.
  • the invention is based on the object to provide a simple and functionally reliable device of the type mentioned, can be processed with the digitally printed sheet to a one or more partial products printed product, the individual sub-products may have different page numbers or formats.
  • Digital printing of printed products has the advantage over conventional methods that the content of two successive printed products can be changed. Another advantage arises from the elimination of time-consuming transport of the printed products over long distances, if they can be printed digitally near their destination.
  • the object is achieved in a generic device characterized in that the second curve between an ineffective, releasing the holding means and a deviating extending curve portion at least approximately canceling, the holding means in effect holding position, can be delivered.
  • a delivery movement of the second curve is required in the inventive device.
  • Such a movement can, for example, take place parallel or radially to the axis of rotation of the collecting cylinder or by pivoting about an axis parallel to the axis of rotation of the collecting cylinder. It has been shown that the rapid delivery of the curve with the inventive device, a particularly high performance is possible.
  • the device according to the invention is particularly suitable for collecting printed sheets which are printed sequentially in a digital printing press.
  • a digital press is capable of printing with different formats and page numbers without manual intervention.
  • the device according to the invention is particularly suitable for gathering so-called plano sheets, which are collected on the collecting cylinder and folded in a folding unit after further transport. It is possible in this case to process an alternating number of printed products and in particular of sheets, which may also have different formats. It is essential here that the collection of the printed products on the collecting cylinder can be completely separated from other functions, for example from cross-cutting and folding.
  • a particularly simple embodiment results when, according to a development of the invention, the second curve of a curve segment is formed.
  • a curve segment can be brought linearly or by pivoting into the operative position with a predetermined stroke.
  • a positioning cylinder and preferably a pneumatic cylinder with which the curve, or the curve segment, approximately linearly displaced or pivoted about an axis is.
  • the lever for controlling the holding means is a double roller lever, a first roller cooperating with the first curve and a second roller with the second curve. Both roles are firmly connected.
  • the deliverable second curve for actuating the holding means is electrically controlled by a controller which also controls the units of the device according to the invention, for example a digital printing press and a cross cutter.
  • a controller which also controls the units of the device according to the invention, for example a digital printing press and a cross cutter.
  • a development of the invention provides that for the further transport of the collected printed products on the circumference of the collecting cylinder a controlled switch is arranged, which engages in the collecting cylinder as soon as the holding means have released the sheets. With such a switch, it is possible to lift the collected printed products very quickly and safely from the collecting cylinder and fed by means of a conveyor to a folder.
  • the switch is according to an embodiment of the invention between a first position in which the printed products on the collecting cylinder be collected, and a second position in which the collected printed products are discharged pivoted.
  • the inventive device allows a particularly fast and safe switching of the switch, which must be done in each case in a small gap between the collecting cylinder or the collected on the collecting cylinder sheet.
  • the switch is controlled by a co-rotating with the collecting cylinder control member. This makes it possible in a simple and safe way to control the switch angle synchronous to the collecting cylinder.
  • the control member has a control cam, such that the switch moves up and down between an incoming printed product and a printed product located on the collecting cylinder.
  • the control of the switch is preferably carried out with an actuating element which has a support roller which cooperates with said control member.
  • the latching is particularly simple and safe if, according to a development of the invention for latching the switch a pawl is provided which has an ineffective and an effective position.
  • a particularly rapid switching of the pawl is possible if it is fixed according to an embodiment of the invention by an actuator, preferably by a pneumatic actuating cylinder in the operative position.
  • the fixation can be particularly easily done with a stop, by the piston rod of the pneumatic cylinder is formed.
  • the actuator is preferably controlled by the above-mentioned control, so that a clock-synchronous switching of the switch is guaranteed.

  • the drive motor 13 also drives via the toothed belt 14 and a toothed belt 15 to a lower conveyor belt 44, which is placed over rollers 45 and 46.
  • a counter-pressure roller 12 is engaged with both the timing belt 14 and the timing belt 15. Furthermore, the drive motor 13 drives an acceleration element 11 via the toothed belt 14, which cooperates with the counterpressure roller 12 to accelerate a printed product 17 to be collected.
  • the acceleration member 11 has at its periphery a surface 49 which rotates in the direction of the arrow 48 about an axis 47.
  • the drive motor 13 drives via the toothed belt 14 and a toothed belt 59 to an upper wheel 51, which is a spur gear, which engages in a lower wheel 52 of a conveyor 6, which is also a spur gear.
  • the upper wheel 51 drives an upper conveyor belt 10 and the lower wheel drives a belt 53.
  • the collecting cylinder 2, the accelerating member 11 and provided for transport belts 10, 44 and 53 are thus clocked and driven at the same speed via the drive motor 13.
  • the required information receives the drive motor 13 from the controller 16, which in Fig. 1 is indicated and which is also a printing press 56, which is preferably a digital printing machine, and a cross cutter 57 controls.
  • the in Fig. 1 also merely indicated and known cross cutter 57 cuts the printed by the printing machine 56 paper web 67 transversely to the transport direction into individual printed products 17.
  • the transport of the printed products 17 takes place in Fig. 1 according to arrow 50 from left to right.
  • the speed of the cross cutter 57 which has at its periphery a blade merely indicated here, corresponds exactly to the rotational speed of the accelerating member 11, or half the rotational speed of the collecting cylinder 2, which can form two sheet stacks 18 and 18 'on its cylinder circumference.
  • the collecting cylinder 2 thus has two so-called benefits. It is also conceivable, however, an embodiment in which the collecting cylinder 2 is formed only for one or more than two benefits.
  • the holding means (5) may be formed, for example, as a puncturing needles, each according to Fig. 3 are attached to the end of a lever 4.
  • the acceleration element 11 and the puncturing needles on the collecting cylinder 2 are adjusted to one another such that the printed products 17 are impaled by the extended puncturing needles about 1 cm behind a leading edge.
  • the lever 4 dive with the holding means 5 and collected to a sheet stack 18 printed products 17 are released on the collecting cylinder 2.
  • a last printed product 17 is placed directly on the collected on the collecting cylinder 2 sheet stack 18 without this is held by the holding means 5 and guided around the collecting cylinder 2.
  • FIG. 1 the position of the holding means 5 and the lever 4 is shown in solid lines, in which the holding means 5 for collecting printed products 17 in effect.
  • the retracted position in which these collected print products 17 are free on the collecting drum 2 is in FIG Fig. 1 shown with dashed lines.
  • the levers 4 are at a distance from the holding means 5 fixed to the in Fig. 3 shown shaft 28 connected.
  • This shaft 28 is rotatably mounted in the collecting cylinder 2.
  • an actuating element 19 is attached, which according to the Figures 2 and 3 has two cam rollers 20 at a distance from the shaft 28.
  • the cam follower 20a shown on the right runs at least partially on a path 21a of a curve 23 and the cam roller 20b on a path 21b of a curve 24.
  • the curves 23 and the curve 24 are stationary, ie they do not rotate with the collecting cylinder 2.
  • the curve 24 is For example, axially displaceable, with the in Fig. 3 shown stroke.

  • the second curve 24 is pivotally mounted about the axis of rotation 22 or about an axis parallel to the axis of rotation 22.
  • the curve 23 is not displaceable, it is fastened with a plurality of bolts 27 on the machine frame 30. If the curve 24 is delivered in the axial direction, it is guided linearly by a guide element 25.
  • the drive for the axial movement takes place with a pneumatic cylinder 26 which is fixed to the machine frame 30.

If the curve 23 in the in Fig. 3 shown with solid lines, extended position, so the different curve portion 23a is not effective because the actuator 19 is raised in the region of this deviating curve section 23a with the cam roller 20b on the curved portion 24a of the curve 24. The deviant curve section 23a is thus at least approximately canceled by the curve 24. In the Fig. 2 the corresponding position of the lever 19 is shown in solid lines.
