Definitions

  • the present invention relates to a book clamping device in a book binding machine, in particular a book clamp device for clamping books along with them Length of varying thickness is suitable.
  • book clamping devices are usually used previously collected from a bundle of individual signatures or sheets existing book, brochure, magazine or magazine, hereinafter commonly referred to as a book, clamp tightly to the variety of sheets or signatures before the next step of binding by applying glue on to hold the spine together.
  • the sheets or signatures are held so firmly that they can be transported through the binding machine in which a number of to Binding the book necessary processing steps are carried out.
  • Such a clamping device is such.
  • B. is known from US 3,702,129.
  • In this Document describes a bookbinding machine that has a variety of together coupled and driven by an endless chain along a trajectory Includes clamping devices.
  • Each of the clamps includes an outer one Clamping arrangement which can be pivoted on a horizontal axis inner clamp assembly is attached.
  • these clamping devices cannot adapt to slight fluctuations in the thickness of the books along their length, such as, for. B. caused by inserts inserted into the book that are of a different length than that Have sheets or signatures of the book.
  • the object of the present invention is to provide a book clamping device, in particular to create a book clamping device for a binding machine, the one sufficient clamping force over the entire length of the clamped book section exercises, even if the thickness of the clamped book section varies.
  • the book clamping device according to the invention for a book binding machine comprises preferably a first clamping element and one adapted to the first clamping element second clamping element which is connected to a first flexible spring plate.
  • the book clamping device comprises for a bookbinding machine, preferably a first clamping element and one with the first Clamping element connected second clamping element on which a first and a second flexible spring plate are attached.
  • the second clamping element Book clamping device By attaching a flexible spring plate to the second clamping element Book clamping device, it is possible to adjust the clamping force to slight fluctuations in thickness Adjust the length of the book along its length, especially by inserting inserts can be caused in the book that are smaller than the sheets or signatures of the Book.
  • the shape of the spring plates makes contacting the book in two enables contact lines running parallel to the direction of the spine, which creates a pressing force orthogonal to the direction of the spine is generated, which increases the frictional force significantly and therefore a very safe Holds the book in the clamp.
  • a book clamping device according to the invention is shown, the first Clamping element 10 and one in a hinge point 14 on the first clamping element 10 includes pivotally attached second clamping element 12.
  • the second clamping element 12 is preferably on the pressure element 16 a spring plate 18 attached.
  • a book 20 which is a variety of sheets or Signatures can include.
  • the outer clamping element 12 does not contact the book 20 directly, but only via the spring plate 18.
  • This spring plate 18 is, as already mentioned, on outer clamping element 12 attached.
  • the spring plate 18 can advantageously in particular be arranged on a pressing element 16 which forms part of the outer Clamping element 12 forms or is connected to the outer clamping element 12.
  • Fig. 2 shows a schematic side view of the pressing element 16 of the second Clamping element 12.
  • the pressure element 16 can have a pressure plate 17 that a Be part of the pressure element 16 itself or be attached to the pressure element 16 can.
  • At the end of the pressure plate 17 facing the book 20 there is a spring plate 18 attached.
  • the spring plate 18 has a convex cross section and contacts the book 20 accordingly in the side view in the two contact points 22, 24. Due to an insert 26, the book 20 is thickened in the area indicated by the route A. If that Book 20 is gripped by the clamping device, the spring plate 18 touches the book in the touch points 22, 24.
  • the pressure exerted on the book 20 is accordingly regardless of the thickness of the book 20 and any changes in thickness in y- or x-direction of the book 20. In this way, changes in thickness in y- or x-direction of the book 20 by attaching the flexible spring plate 18 to the Pressure plate 17 or generally compensated for on the second clamping element.
  • Fig. 3 shows a schematic, perspective view of the second clamping element of the Book clamping device.
  • the second clamping element 12 (FIG. 1) comprises the pressing element 16 with a flexible spring plate 18, which is a substantially concave, on the edges 28, 30, however, has a convexly curved cross section. Due to this slightly convex curved edges become pressure marks or other damage to the book 20 avoided during the clamping process.
  • the spring plate 18 can by means Fasteners 32, e.g. B. rivets or screws, preferably countersunk or recessed screws, attached to the pressure element 16.
  • the flexible Spring plate 18 also have a different, for example polygonal, cross section.
  • the spring plate 18 having a polygonal cross section comprises a plurality of straight sections represented as sections C, D, E, F and G. It is however, it is important that the different sections of the polygon are so interconnected are that they form a flexible spring plate 18 which is concavely attached to the pressing element 16 can be.
  • FIG. 5 shows a further embodiment of the present invention.
  • the in the The previously described embodiments of the spring plates are generally by means of fastening means 32 preferably arranged in the middle of the spring plate, for example rivets or screws, attached to the pressing element 16.
  • fastening means 32 preferably arranged in the middle of the spring plate, for example rivets or screws, attached to the pressing element 16.
  • fasteners 32 e.g. B. rivets or recessed screws
  • the first spring plate 34 is fastened to the pressing element 16 in such a way that that between the surface 13 of the pressing element 16 and the first spring plate 34 Angle ⁇ is formed.
  • the second spring plate 36 is fastened to the pressing element 16 in such a way that that the surface 13 of the pressing element 16 and the spring plate 36 form an angle ⁇ form, which is greater than the angle ⁇ .
  • the angle ⁇ is less than 45 °, preferably less than 30 °, and is in particular between 1 ° and 10 °.
  • the angle ⁇ is less than 60 °, preferably less than 40 ° and is in particular between 2 ° and 15 °.
  • the flexible spring plates 34, 36, 18 described above can be made from any suitable material, for example made of a polymer such as polyethylene, Polypropylene, polystyrene etc., or from a metal, e.g. B. a bent metal sheet.
  • the flexible spring plates can be used with the second Be connected to the clamping element and in particular by means of rivets or screws on this be attached.
  • two spring plates preferably different sizes or different shapes and preferably attached to the same fastening points on the second clamping element 12, by z. B. at an attachment point the same screw or rivet for attachment both spring plates is used.
  • the compression force of the first and second Pressure element can be selected by choosing the appropriate material or different Thicknesses can be changed. Since one of the spring plates is usually shorter than the other, it can also be made thinner since it has a shorter lever arm.
