Definitions

  • the invention relates to a clamp for one Endless conveyor according to the generic term of Claims 1 and 4.
  • EP-A-03 86 442 is a generic one Clamping pliers for endless conveyors known, in which one first fixed jaw from an open position against the first jaw movable, pivoted second Jaw is arranged.
  • the swiveling jaw is on a first lever arm of a three-armed lever arranged.
  • On a second lever arm is one Actuating roller for actuating the jaw in your Open and closed positions stored.
  • a third Lever arm is part of an initiation device a clamping force is formed, the actuation of Jaw this device overcomes a dead center.
  • US-A-30 55 480 describes an endless conveyor for Paper products, where the paper products are between two Jaws are held by self-locking. A the jaw is opened by means of a lever operated directly.
  • the invention has for its object a To create clamping tongs for endless conveyors.
  • the movable jaw acts in a closed position on the jammed printed product. This means that the printed product to be transported cannot be pulled out and thus lost. Furthermore, the presence of the self-locking jaws means that large spring forces can be dispensed with. This results in a longer service life for the components of the clamp.
  • the clamp is designed without a housing.
  • Each Clamping pliers have a base of clamping pliers, which forms a stop for the products to be picked up. This stop ensures a gentle recording as well an error-free delivery of the goods to be transported Product.
  • a simple, component-friendly force curve having construction is achieved in that in one the lever carrying the jaw additionally one Actuating force and / or the clamping force initiated becomes.
  • a pair of pliers 1 for an endless conveyor for example a rotary printing machine.
  • B. chain conveyor consists essentially of a fixed to a chain link 2 of a traction means of the chain conveyor by means of a carrier 3 fixed first jaw 4 and a cooperating with the first jaw 4 second jaw 6.
  • the chain link 2 has at least on both ends a roller 5, which runs in a chain guide, not shown.
  • chains ropes, belts or toothed belts can also be used as traction means, for example.
  • the carrier 3 of the first jaw 4 is z. B. L-shaped educated.
  • a short leg 7 of the carrier 3 runs at right angles to a longitudinal axis 9 of the Chain link 2 and is connected to the chain link 2.
  • a long leg 8 of the carrier 3 is parallel to that Longitudinal axis 9 of the chain link 2 arranged.
  • An outside End 11 of the long leg 8 is V-shaped and connected to the first jaw 4.
  • One of them formed jaw base 10 has a radius r10 on. The radius r10 is larger than a radius of one Front edge 12 of one using the clamping pliers 1 transported goods, e.g. B. a printed product 13th (Fig. 2).
  • the carrier 3 has a right angle to the longitudinal axis 9 of the chain link 2 extending bore 14.
  • This bore 14 is a pivot axis 16 of a lever 17 arranged.
  • the lever 17 has a first lever arm 18 on which the adjustable, pivotable jaw 6 is attached and in which the operating forces be initiated.
  • the first lever arm 18 is on its extended, free end with a roller 19 for Actuation of the lever 17 provided.
  • the second lever arm 22 has a bearing pin 23 at its end, which as a force application point 24 for an end one as Lift mechanism designed tension spring 26 is used.
  • the Tension spring 26 has an abutment 27 at its other end, which with one at the end 11 of the long leg 8 located bearing pin 28 is operatively connected.
  • the carrier 3 which is L-shaped in cross section extends in a direction parallel to the swivel axis 16.
  • the carrier 3 has at least the width of one Chain link 2 on.
  • the first on the carrier 3 Clamping jaw 4 is wider, e.g. B. twice as wide as that Carrier 3.
  • the lever 17 can on the pivot axis 16 each arranged on both sides of the carrier 3 and by means of second jaw 6 may be connected. So are also two tension springs 26 are used and each of the first two Lever arms 18 carry a roller 19.
  • the second jaw 6 can be on your against the inside of the first Provide jaw 4 acting end with a radius his. This will cause unwanted imprints on Printed product 13 avoided.
  • a distance a1 between the end of the jaw 6, ie the contact zone of printed product 13, and the pivot axis 16 of the jaw 6 is preferably somewhat larger than the shortest distance between the pivot axis 16 and the inside of the jaw 4.
  • the clamping jaw 6 is placed against the printed product 13 in such a way that the printed product 13 is clamped between the two clamping jaws 4, 6.
  • Self-locking acts on the printed product 13 in the closed position.
  • a straight line 33 defined by the end of the clamping jaw 6 (ie the contact zone formed by the printed product 13 and the clamping jaw 6) and the pivot axis 16 of the clamping jaw 6 and one in a contact zone of The printed product 13 and the clamping jaw 4 created a tangent 34 an opening angle ⁇ (alpha).
  • this opening angle ⁇ is referred to below as the opening angle which is enclosed by the two clamping jaws 4, 6.
  • This opening angle ⁇ which is necessary for self-locking pointing away from the jaw base 10, depends on the coefficient of friction between the jaws 4, 6 and the printed product 13 and is greater than 45 °, preferably greater than 60 °, and less than 90 °.
  • a printed product 13 held between the end of the second jaw 6 and the inside of the first jaw 4 cannot be pulled out.
  • the function of the clamp 1 is as follows: The clamping tongs 1 arranged on a chain link 2 of the chain conveyor are initially in an open position A (FIG. 1). At a loading station, e.g. B. a paddle wheel of a folder, a printed product 13 is guided between the jaws 4, 6. As a result of the actuation of the first lever arm 18 in the clockwise direction of rotation D, the bearing pin 23 describes a circular arc around the pivot axis 16 with the force application point 24. The radius of the circular arc corresponds to the length of the lever arm 22.
  • the force application point 24 of the tension spring 26 passes from a stable position A below Coming from a dead center position B, a dead center position B. The tension spring is tensioned.
  • the dead center position B is represented by a straight line 29 which connects the force application point 24 of the tension spring 26, the pivot axis 16 of the lever 17 and the abutment 27 of the tension spring 26. After passing this dead center position B, the tension spring 26 contracts again. The free end of the second jaw 6 lies against the printed product 13 in the closed position C (FIG. 2).
  • the stable positions in open and closed positions A, C the second jaw 6 are achieved in that a distance between the force application point 24 and Abutment 27 of the tension spring 26 in open and Closed position A, C is less than the length of the Dead center distance, d. H. this distance in Dead center position B.
  • the jaw 6 is thus in the open and closed position and finally by the Lift mechanism 26 held, d. H. without permanent Actions z. B. a curve control.
  • the thickness of the Print product 13 can be between 0.1 mm and several Millimeters.
  • the first Lever arm 18 of a lever 32 another roller 31st assigned. This role 31 is between the first role 19 and the jaw 6 arranged.
  • the arrangement of an additional roller 31 to the roller 19 is advantageous in that the switching of the second jaw 6 in the end position A, C over different roles 19, 31 can be made.
  • lever 17, 31 having two lever arms can also be provided only a single lever arm. On this single lever arm is then the adjustable one Clamp 6 attached and it will be the Operating forces for the movement of the jaw 6 in their open and closed positions as well as the clamping forces initiated.
