Definitions

  • the present invention relates to a book block tongs for clamping and transporting book blocks in book block processing machines according to the preamble of claim 1.
  • the book block processing machines have a transport system, which is composed of a plurality of equally spaced from each other, in a closed orbit continuously movable book block pliers. These run in a guideway and are drivingly connected to a transport chain.
  • the outer jaw of the book block pliers is horizontally and at right angles to the direction of movement of the book block pliers, the book block pliers between a closed position for clamping and an open position for executing or feeding the book block are controllable.
  • a book block tongs of the type mentioned is shown for example in DE-OS 21 10 836.
  • This carries at the ends of its outer jaw racks, which are longitudinally displaceable axially in the inner jaw and which are engaged with pinion end of a mounted in the inner jaw parallel to the outer jaw axis.
  • the two racks are brought together behind the inner jaw by a bracket, which causes the movement to open and close by running on a cam roller.
  • the clamping force is applied to hold the book block.
  • the torsion spring spans with increasing distance between the jaws, whereby an effective clamping force of the book block pliers is set depending on the block thickness.
  • the application of a defined, independent of the block thickness clamping force is not possible.
  • To hold the open position of the clamping device ultimately serves a backstop in the form of another, arranged on the axis of the coil spring.
  • Another book block pliers is provided in DE 32 07 102 C2 under protection, which provides parallel guided jaws.
  • the outer jaw is guided freely displaceably via a sliding guide on a guide rod, which is located on one side of the inner jaw.
  • the outer jaw itself consists of a Clamping plate, which is received by means of a parallel link arrangement of the sliding guide.
  • a compression spring which exerts a clamping force on the book block, wherein the clamping force increases with increasing deflection of a defined biasing force to the maximum force.
  • the contact pressure on the freely displaceable on the guide outer jaw takes place from a side of the path of movement of the rotating book block pliers installed closing curve, on which a cam roller of the sliding guide of the outer jaw strikes.
  • the distance of the closing curve to the inner jaw can be adjusted according to the book block thickness or the desired applied clamping force.
  • a self-locking eccentric lock is located on the sliding guide and locks the outer clamping jaw on the guide when an outward-acting force occurs.
  • the opening stroke of the book block pliers to be kept to a minimum.
  • a maximum opening stroke is provided which is designed for a book block with voluminous paper and maximum block thickness.
  • To reduce the opening stroke only a partial stroke of the respective curve is used, wherein the cam roller meets a rising curve edge and thereby triggers a corresponding shock and jerk in the opener and / or closing movement.
  • book block processing machines are known in which the book block pliers are always operated with the full turn of the curve, the cam roller starts smoothly and smoothly to the curve.

  • the inventive idea is that the outer jaw of the book block pliers is associated with a support member which is movable by control means in a position spaced parallel to the outer jaw, whereby the opening width of the book block pliers is reduced, while the distance between the inner and the outer jaw remains unchanged ,
  • the separate control of the opening width allows reliable and perfect guidance of unstable layers and / or folded sheets unbound book block, while the opening and / or closing movement of the outer jaw is still controlled by a fixed, larger operating stroke.
  • the reduction of the opening width of the book block pliers is preferably carried out in the import area of the book block processing machine at a time when at least one block corner of the supplied book block is located between the open jaws of the book block pliers.
  • the book block pliers for inserting the block corner is wide open, while their opening width is set in the further course of the feed according to the unclamped block thickness for safe lateral guidance of the layers and / or single sheets.
  • the support element is pressed by a against the outer jaw supporting spring against the outer jaw. Without the action of the control means is thereby the support element on the outer jaw, for example, to exercise a force acting directly on the book block clamping force through the outer jaw.
  • the control means is a control cam which acts on a cam roller of the support element.
  • the opening width for the supply of the book blocks is set.
  • the adjustment of the opening width can also be effected in that the control cam is connected to a ⁇ ffner- or closing curve of the outer jaw, wherein the distance of the control cam to the relevant ⁇ ffner- or closing curve is adjustable. It is almost the additional opening dimension of the book block tongs to the set block thickness at Feeding the book blocks set. The reduction of the opening width is dependent on the difference between the clamped and unclamped block thickness.
  • control cam has an inlet section with a variable, adjustable to the extent of the opening width reduction curve.
  • the cam roller of the support element thereby runs shock and jerk-free to the control cam.
  • the inlet section can be formed from an elastic support which is fixedly connected to the control cam and which is received at the end by a cantilever of the opener or closing cam. This eliminates a further separate adjustment.
  • the outer jaw is restricted tilted guided to the inner jaw.
  • the support element is expediently designed to be elastic, wherein it has a longitudinal stiffening.
  • the support element has a plurality of bolts oriented perpendicular to the support surface and guided in spherical bearings of the outer clamping jaw, wherein a centrally arranged guide rod is linearly guided.
  • the above-mentioned cam roller of the support element is arranged at the end of this centrally arranged guide rod.
  • the book block processing machine has a transport system which is composed of a plurality of mutually equally spaced, in a closed orbit continuously movable book block pliers 1.
  • the book block tongs 1 run in a guideway and are with a Transport chain 3 drivingly connected. They consist essentially of an inner jaw 5 with horizontal and vertical guide rollers 4 a and 4 b and a parallel to this and arranged to the inner jaw 5 relatively movable outer jaw 6, wherein book block 2 by applying a clamping force between the two jaws 5 and 6 are clamped.
  • the outer jaw 6 is guided freely displaceably via a sliding guide 8 on a guide rod 7, which is located on one side of the inner jaw 5.
  • the outer jaw 6 itself consists of a clamping plate 11 which is received by means of a parallel link arrangement 9 of the sliding guide 8. Between the parallel link assembly 9 and the clamping plate 11 is a compression spring 10 which exerts a clamping force on the book block 2, wherein the clamping force increases with increasing deflection of a defined biasing force on the maximum force.
  • the contact pressure on the freely displaceable on the guide rod 7 outer jaw 6 takes place from a laterally the movement path of the circulating book block pliers 1 installed closing curve 13, on which a cam roller 12 of the sliding guide 8 of the outer jaw 6 applies.
