Definitions

  • the invention relates to a pit cover for covering a gap region between a sheet conveying device and a printing machine with at least one perpendicular to a sheet conveying direction extending guide element for guiding at least one movable an adjustable lateral stop for paper sheets forming side member and a plurality of individual, sliding support members, wherein the support elements and the at least one side element cover the gap region in variable width.
  • Such a pit cover is for example from the DE 42 40 660 C1 known.
  • This document discloses an arch support device with two transversely extending to the conveying direction parallel trusses on which a plurality of guide bridges is mounted. These guide bridges have on at least one side surface an elastic bending spring, which is supported on an adjacent guide bridge.
  • a similar pit cover is also from the EP 0268 693 B1 known, in which the individual receiving elements are formed of thin deformable plate material in U- or V-shape, wherein the legs of adjacent receiving elements touch each other.
  • the receiving elements themselves also form the springs. It also applies in this embodiment, the elastic limit of the receiving elements when pushed together not overwrite, so that here too the adjustment is limited.
  • the object of the invention is to provide a pit cover in which the adjustment between minimum and maximum width is improved and the construction is as simple as possible.
  • This object is achieved in that the at least one side member and the support members are connected to each other, in particular fixed, that at a displacement of a side member to a larger width by means of at least one connecting element, a tensile force on the support members exercisable.
  • the pit cover In the pit cover according to the invention, it is provided to guide at least one stop-forming side member and a plurality of support elements on or by means of at least one guide element transversely to the conveying direction of a sheet slidably to set different stops for sheets with the sliding side member and the gap area between a printing press with the support elements and an apparatus for supplying sheets and to support the sheets.
  • the carrying elements and the at least one side element can also be guided on or by means of a plurality of, in particular two guide elements, especially in the form of two parallel rails.
  • These may for example be formed by a frame which constitutes an essential element of the pit cover, and whose two opposite frame parts form two guide elements on which the support elements can be stored.
  • the manner of displaceably guiding the support elements by means of the guide elements is essentially known from the prior art.
  • An essential advantage of the invention is that the individual support elements and the side elements are connected to each other by at least one connecting element, in particular with each other.
  • the one or more connecting elements are constructed and / or arranged such that by means of one or two opposing side elements, the individual support elements can be pushed towards each other. Due to an elimination of constructive spring elements between the individual support elements they can be pushed together in the ideal case to direct contact with each other. As a result, the minimum adjustable width of the pit cover over the prior art can be significantly reduced.
  • a maximum distance between adjacent support elements or between a side element and a support element is defined by at least one connecting element. This is achieved in particular when a connecting element can not be stretched to over a maximum length, but can be compressed when the supporting elements are pushed together.
  • a connecting element flexible, but in terms of its maximum length in essential nonelastic.
  • Such a connection element can for example also be telescopic.
  • a preferred connecting element may e.g. be formed by a rope or tape or wire, which extends in the direction of displacement between a side member and an opposing region of the pit cover, in particular a second side member, wherein each support member is fixed to the connecting element.
  • Such a connecting element may be referred to the width, e.g. be attached at one end of the pit cover in this and in the width direction, i. Pull transversely to the conveying direction of an arc through the pit cover and be attached to a side member at the other end.
  • the connecting element can be fastened between them.
  • a side member can be easily moved in the direction of lesser widths, but is stopped in the direction of larger widths when reaching the maximum extension of the connecting element in the manner of a stop.
  • the individual support elements may preferably be fixed equidistantly or at any distance on or on the connecting element.
  • fixing the support elements to a connecting element the person skilled in the art can e.g. take any known action known to him.
  • a support element has a bore or recess through which such an abovementioned connecting element, that is, for example, a flexible cable is threaded through.
  • a fixation between the support element and the connecting element is achieved, for example, the connecting element in the bore or recess glued, clamped, soldered, welded or otherwise secured.
  • rope-shaped fasteners a knot at least in the direction of pull in front of a support element, but preferably on both sides of a support element.
  • a support element has at its outermost lateral edge at least one slot into which a rope or band-like connecting element can be firmly clamped.
  • several slots in a lateral edge can be arranged one above the other, wherein a connecting element is passed successively in S-shape through the slots and so a self-locking is achieved.
  • a side element If a side element is now displaced in the direction of greater width, then it will move away from the support element arranged next to it until the maximum possible distance between these elements is established on the basis of the at least one connecting element.
  • the connecting element When the connecting element is maximally stretched between two adjacent elements, the tensile force of the side element is transferred to the next support element and this entrained and so on, until that the connecting element between all support elements is maximally stretched. In this case, the maximum adjustable width is reached.
  • At least two parallel juxtaposed connecting elements in particular in the manner of a rope or band are provided in the displacement direction. This ensures that the force effect is equalized when pulling on the support elements, in particular right and left side is the same, so that the support elements maintain a preferred orientation perpendicular to the direction of displacement.
  • two, in particular ribbon or rope-like connecting elements parallel to each other through the pit cover.
  • a support element in the form of a plane oriented perpendicular to the displacement surface element, in particular in the form of a sheet is formed.
  • Support elements of this form can be made very thin, so that with maximum collapse of all support elements a minimum pit width is adjustable.
  • a support element has at least one projecting area and a recessed area, wherein a projecting area of a support element is recessed Area of an adjacent support element rests. In this way, a stabilizing loose connection of the individual support elements can be achieved with each other.
  • a support element as a surface element, for example made of sheet metal
  • at least one area in the form of a tab is bent out of the surface of a surface element in the direction of displacement and rests in the resulting recess a corresponding tab of an adjacent surface element.
  • Such a flared tab can be achieved e.g. by a U-shaped punching or a U-shaped cut (for example by means of laser) which results in a flap in the flat material which can continue to be exposed at the remaining connecting edge to the surface element from the surface at any angle.
  • a deployment angle of 60 degrees.
  • a planar support element to arrange two such abovementioned tabs next to one another, in particular wherein the respective bending edges are assigned to one another or lie next to one another.
  • FIG. 1 shows a support member 1 in the form of a thin sheet.
  • two opposing recesses or grooves 2 and 3 are provided within the support member 1 right and left, by means of which the support member 1 can be guided and stored on spring-shaped projecting rails 4 of the pit cover or the guide elements 5 provided therein.
  • the guide elements 5 extend with respect to the FIG. 1 perpendicular to the sheet plane in the longitudinal direction of the pit cover.
  • three bores 6 are provided through which, for example, a connecting cable 7 or band can be passed as a connecting element, so that all supporting elements 1 pit cover are strung on this band or rope in succession, such as the FIGS. 2a and 2 B demonstrate.
  • a connecting cable 7 or band can be passed as a connecting element, so that all supporting elements 1 pit cover are strung on this band or rope in succession, such as the FIGS. 2a and 2 B demonstrate.
  • the support element 1 can be fixed on / on the cable 7.
  • the cable 7 through the three holes 6 in various ways forward and back, for example, to guide S-shaped through the holes, resulting in a self-locking.
  • a cable 7 coming from the upper bore 6 of a support member 1 c go through the lower bore 6 of an adjacent support element 1 d, again through the central bore 6 of the Tragierisl d be returned to then again after passing through the upper hole. 6 of the support element 1 d to reach the next support element 1e.
  • an S-shaped deflection is achieved.
  • the bores 6 are respectively arranged in the vicinity of the rail-shaped guide elements 5, to ensure a uniform application of force when pulling through a not shown side member on both end portions right and left of a support member 1 and to prevent so that the support elements 1 in the guide at an angle move.
  • FIG. 1 It is in the same way FIG. 1 to recognize that from the surface of the support element 1 two adjacent tabs 8 are angled, each taking a preferred angle of eg 60 degrees to the surface.
  • the tabs 8 can be made for example by punching or cutting and subsequent folding and leave in the sheet material when kinking ever a recess 9, which can serve to receive a tab 8 of an adjacent support element 1.
  • the nesting of the support elements 1 with the individual tabs 8 is in the FIGS. 2a and 2 B particularly recognizable.
  • FIGS. 2a and 2 B each show an overall view of a pit cover with a plurality of support elements 1, which here have a maximum possible distance from each other, which is given by the cable attachment. Between the support members 1 extends close to the outer guide rails 5, which in the FIGS. 2a and 2 B not shown are the rope or band 7, to which the support elements 1 are respectively attached.
  • the maximum distance is set here so that the end portion of a tab 8 of a support element 1 is still at maximum distance in the recess 9 of an adjacent support element 1 rests, or preferably penetrates through this recess 9. This will be with reference to FIG. 2b achieved stability against bending of all support elements 1 perpendicular to the page level.
  • the support elements 1 a and 1 b at the respective end portions have a different construction, for. can be fastened with screws to side elements, not shown, which serve as side stops for sheets, e.g. Can serve paper sheets.
  • the screws or similar fasteners may be arranged such that when pushed together the recesses 9 of the support elements 1 put over the screw heads 10 of the element 1 a and / or the heads of the screws 11 between the lugs 8 of the element 1 b are arranged.
  • FIG. 3 shows the individual support elements 1 in the fully pushed together state. It can be seen that the support elements can be pushed together to the smallest distance, in the ideal case, even directly on top of each other. Optionally, the distance may be given by the thickness of the connecting cable 8, which may lie in the collapsed state between the support elements 1.
  • a connecting cable is attached to the outer edges on the right and left of the support elements 1 and in the collapsed state is adjacent to the support elements 1.
  • the support elements 1 can touch the entire surface.
  • the pit cover according to the invention has the advantage that the minimum pit width (apart from the end elements or side elements) can essentially correspond to the sum of the thicknesses of all the individual support elements 1.
