Definitions

  • the invention relates to a separating suction device for a feeder of a printing machine with suction pads for lifting the top sheet of a stack of sheets and for transferring the sheet that has been lifted off to transport means for conveying the respective sheet that is lifted off in a direction of sheet travel in the direction of a printing unit of the printing machine, the suction pads in the Are arranged near the trailing edge of a respective sheet above the sheet stack and the suction grippers first capture the uppermost sheet in each case when they are acted upon by suction air and then carry out a self-lift to a first height, as well as with a lifting gear which carries a horizontal, to the trailing sheet edge parallel support axis, against which the suction pads are aligned, in a respective upward stroke and a respective downward stroke in time with the printing press on a substantially straight, vertical path so raises and lowers t that the suction cups are raised to a second level above the first level during an upward stroke.
  • Such a device is known for example from DE-AS 19 29 714.
  • the suction pads are clamped in particular on the support axis such that they can be pivoted in and against the direction of sheet travel.
  • the fact is taken into account in the prior art that the surface of the sheet stack at its stack edges deviate from a horizontal plane and can be convex or concave in a direction perpendicular to this plane, the trailing sheet edge being deeper in the case of convex curvature and in the case concave curvature is higher than the areas of the stack surface located towards the center of the sheet.
  • Stacking edges of the described convex shape occur, for example, when printed sheets with non-printing edges are stacked in large numbers.
  • the clamping of the suction grippers is released in the known device and their rotationally fixed connection to the supporting axis is restored in a swivel position of the suction grippers adapted to the curvature of the stack surface.
  • This is intended to ensure that, in particular, sheets with a relatively high basis weight can also be separated from a stack of the form described without interference. Without adapting the inclination of the suction pads to the surface of the stacking edge, such disturbances can occur that the sheets are not reliably grasped by the suction pads.
  • a separating suction device is known from DE-OS 36 09 549, the suction grippers of which can also be pivoted during operation of the printing press in the sense of adaptation to curved stack edges.
  • This device has guides that can be pivoted about a stationary horizontal support axis in and against the direction of sheet travel, in which the suction pads execute an upward stroke following the respective pivoting direction of the guides after the top sheet has been gripped.
  • the stroke distance to be covered depends in particular on the format and the weight per unit area of the stack bow to be lifted. Sheets with a large format and high basis weight require a correspondingly longer stroke distance than sheets with a smaller format and lower basis weight.
  • the sheets gripped by the suction grippers are already transported in the area of the respective sheet in or against the sheet running direction when the guides are inclined in or against the sheet running direction during the lift-off, that is to say before they are handed over to suction cups.
  • a sheet lifted near a trailing edge of a sheet from an underlying sheet of the stack can exert a thrust force acting in the sheet running direction on the sheet below with its areas still lying on the sheet below if the lifted sheet is transported in the sheet running direction with the aid of drag suction devices .
  • this pushing force can also result in the sheet lying under the uppermost sheet also being transported in the sheet running direction, however, unintentionally, and thus being fed to the printing machine in an unprogrammed manner.
  • the uppermost sheet is taken along by the suction cups before it is taken over by the suction cups in the direction of sheet travel, the uppermost sheet bulges in the area of its leading edge at the stops of the flap shaft that have not yet been folded away and can therefore result in bend this area downwards during the further transport of this sheet by the suction cups, so that the subsequent areas of the sheet roll over and disturbances in sheet transport are caused.
  • Such disturbances can occur in particular in that the separating suction cups are mounted in inclined guides, the inclination of which gives the uppermost sheet a not insignificant movement in the direction of sheet travel during the lifting of this sheet.
  • the object of the invention is to propose a universally usable separating suction device which, when the separating suction devices are inclined in or against the sheet running direction, does not have any disruptive influences on the transport of the sheet in the sheet running direction following the lifting of the uppermost sheet from a stack and which changes it enables the suction cups to be tilted while the printing press is running without any major operating effort.
  • the separating suction device described at the outset is designed in such a way that the supporting axis can be pivoted about its longitudinal axis in the lifting gear and is connected in a rotationally fixed manner to a handlebar of a pivoting device for the selectable pivoting positions, which is guided essentially parallel to itself in selectable pivoting positions.
  • the lifting gear provided makes it possible to provide suction pads in the form of so-called suction cups, which generally have a shorter internal stroke than so-called drop suction cups, even in the case of larger formats. This, however, also creates favorable conditions for processing so-called absorbent papers, in which otherwise there would be the danger, when using suction cups with a generally longer self-stroke, that further sheets located under the top sheet together with the top sheet from the suction pads are lifted off, causing disruptions in sheet transport.
  • this swivel device is formed from the handlebar, from a vertical first straight guide for an end of the handlebar facing away from the supporting axis, from a second straight guide parallel to the direction of sheet travel for the first straight guide and from adjusting means by means of which the first straight guide both in and is displaceable against the direction of sheet travel on the second straight guide.
  • the parallel guidance of the handlebar in selectable swivel positions is realized with simple construction elements and is attributed to a mere horizontal displacement of a vertical straight guide.
  • the actuating means can be designed in a correspondingly simple manner, which, in a further embodiment of the invention, have an actuating spindle articulated on the second straight guide and an axially lockable spindle nut which cooperates with the actuating spindle.
  • the vertical straight guide has two guide surfaces that are perpendicular to the direction of sheet travel and spaced apart from one another, between which a roller is guided, which is mounted on the end of the handlebar that is remote from the supporting axis and is freely rotatable about a roller axis that is parallel to the supporting axis.
  • Means designed in this way for parallel guidance of the handlebar in its selectable pivoting positions have a wear-reducing effect on the pivoting device and furthermore prevent possible tilting of the handlebar during its lifting movements.
  • the spindle nut is connected in a rotationally fixed manner to a rotary knob.
  • this knob By pressing this knob in one of the two Direction of rotation of the spindle nut, the inclination of the suction pads can be easily adapted to the respective requirements.
  • the spindle nut is in rotary connection with automatic reversible drive means.
  • the reversible drive means are connected to manually operated switching means for selecting the direction of rotation and the number of revolutions of the spindle nut.
  • the switching means are expediently provided with information on the direction of the inclination of the suction pads.
  • the continuously required adjustment of the inclination of the suction pads can be simplified in a further embodiment of the subject matter of the invention by providing a scanning device equipped with at least one first and at least one second sensor, by means of which a curved surface of an edge region of the sheet stack associated with the trailing sheet edge on at least one first and a second measuring location one behind the other in the sheet running direction can be scanned, and that the reversible drive means can be controlled by means of the scanning device as a function of a height difference between the first and the second measuring location.
  • Another embodiment of the invention is characterized by the fact that sensors work in a contactless manner are provided. This opens up the possibility, in particular, of arranging conventional sensors such as reflected light sensors or dynamic pressure nozzles opposite one side surface of the sheet stack, so that a further embodiment of the invention is characterized in that the contactless sensors face a side surface of the sheet stack which is made up of edges of the edges running in the direction of sheet travel Arch stack forming arch is formed.
  • Such an arrangement of the sensors has the advantage that the lifting of the uppermost sheet is not hindered by the scanning device.
  • a scanning device arranged directly above the sheet stack would have to be pivoted away from the sheet stack at least temporarily, in order not to hinder the lifting of the top sheet in each case.
  • the first and the second sensor measured in the direction of sheet travel, are arranged at a mutual distance forming the distance between the measurement locations, and at least one of the sensors is vertically adjustable relative to the other sensor.
  • the sheet stack is usually tracked during the printing process in such a way that the uppermost sheet is at approximately the same height
  • equipping the scanning device with a rigid and a vertically adjustable sensor enables a reduction in the effort required for the scanning device.
  • a sensor which is rigidly arranged in the scanning device can be adjusted to a selectable working height by means of an adjusting device for the scanning device.
  • a further embodiment of the invention proves to be particularly expedient, in which the first and the second sensor can be adjusted vertically relative to the other.
  • the equipment of the separating suction device with a scanning device according to the invention enables a reduction in the operating effort until the inclination of the separating suction devices is automatically adjusted to the curvature of the stack edge.
  • the supporting axis 1 is mounted in the lifting gear 2 so as to be pivotable about its longitudinal axis.
  • the lifting gear 2 corresponds to a known version (DE-AS 19 29 714) of a suction head, of which a side wall 3 is shown in detail in FIG. 1.
  • both ends of the support shaft 1 are equipped with suction pads 4, the suction pads 4 are aligned with the support shaft 1 and the connection nipple 5 of the suction pads 4 is connected to the interior via a flexible tube (not shown) 6 of the support shaft 1 designed as a tube, the interior of which in turn is connected to a controllable vacuum source (not shown).
  • the support shaft 1 For the pivotable about its longitudinal axis of the support shaft 1 in the lifting gear 2, the support shaft 1 according to FIG. 2 is pivotally mounted in a sleeve 8, which in turn via a clamp connection with the lower rod end 9 of a vertically arranged lifting rod 10 of the between the side walls 3 and 3 ' the suction head arranged lifting gear 2 is connected.
  • the link 11 is rotatably connected at one end to the supporting axle 1 and guided at its end facing away from the supporting axle 1 on a vertical straight guide 12, which in turn is guided on a horizontal straight guide 13.
  • the horizontal straight guide 13 is arranged so that it guides the vertical straight guide 12 parallel to the direction of sheet travel.
  • the handlebar 11 In a defined position of the vertical straight guide 12 with respect to the horizontal straight guide 13, the handlebar 11 remains essentially parallel to itself regardless of an instantaneous height of the support axle 1 raised and lowered by the lifting gear during the lifting movements communicated to the handlebar 11 by the support axle 1. Accordingly, the suction gripper with selectable inclination in or against the sheet travel direction is raised and lowered in or against the sheet travel direction without a directional component which has a detrimental effect on the sheet transport.
  • the inclination of the suction pads can be selected by displacing the vertical straight guide 12 relative to the horizontal straight guide 13. Such a shift is also possible during the lifting movements of the lifting gear 2, that is to say while the printing press is running.
  • a lug 14 of the vertical straight guide 12 engages in a horizontal slot in the side wall 3.
  • the nose 14 is secured against falling out of the slot of the horizontal straight guide 13.
  • an adjusting spindle 15 is articulated thereon.
  • the pivoting of the handlebar 11 and its guidance at its end facing away from the supporting axle 1 takes place via the mutually parallel guide surfaces 12a and 12b of the vertical straight guide 12, between which a roller 20 is guided, which can be freely rotated at the end of the handlebar 11 facing away from the supporting axle 1 is mounted around a roller axis 21 parallel to the supporting axis 1.
  • the adjusting spindle 15 works together with a spindle nut 16 which is axially locked between two angles 17 and 18 fastened to the side wall 3.
  • the spindle nut 16 is connected to a rotary knob 22 via a grub screw 19.
  • the spindle nut 16 is connected in a rotationally fixed manner by means of a feather key 23 to the shaft 24 of a geared motor 25 which is flanged to the bracket 18 fastened to the side wall 3.
  • the automatic adjustment of the inclination of the suction pads to the curvature of the stack edge associated with the trailing sheet edge is carried out in accordance with an exemplary embodiment shown schematically in FIG. 5 by means of a scanning device 26.
  • This scans the stack edge with two sensors 27 and 28 at two measurement locations 29 and 30 of Sheet stack 31 and delivers a control signal dependent on the height difference 62 of these measuring locations, with which the geared motor 25 with the spindle nut 16 connected to it is controlled such that the suction pads are inclined so that they are essentially perpendicular to the connecting line of the two measuring locations 29 and 30 stand.
  • a scanning device with non-contact sensors is particularly suitable for automatically adjusting the inclination of the suction cups during the operation of the printing press.
  • a scanning device 26 ' is shown schematically.
  • the non-contact sensors 27 ', 28' can be designed, for example, as reflective light probes or as dynamic pressure nozzles and face a side surface 35 of the sheet stack, where they do not impede the lifting of the top sheet.
  • the sensors 27 ', 28' as well as the sensors 27, 28 are arranged as shown in FIG. 5 in the sheet running direction at a mutual distance 34, which corresponds to the distance between the measuring locations 29, 30. With a setting device, not shown in the drawing, the scanning device 26, 26 'can be moved vertically.
  • a rigidly in the scanning device 26, 26 'arranged sensor 27, 27' can thereby be set to a working height 36.

  • the scanning device 26, 26 ' also has adjustment means (not shown) with which the sensor 28, 28' vertically adjustable relative to the sensor 27, 27 'is automatically adjustable so that it is at the measuring point 30 under a height difference 62 to rigid in the Scanning device arranged sensor 27, 27 'is located.
  • the sensor 28 ' is also located directly below the surface of the sheet stack 31, that is, like the sensor 27', in a position in which, when the sensors 27 ', 28' are designed as reflective light probes, the sensor 28 ' is just covered by the sheet stack.
  • the adjusting means with which the automatically adjustable sensor 28 'is set to the height difference 62' with respect to the rigid sensor 27 ', can be created on the basis of the teachings of DE-OS 32 10 943 and installed in the scanner 26' so that a there is no need to go into detail about this.
