  • the movable clamping jaw is held in its closed position by means of a ratchet coupling.
  • a ratchet wheel is connected in a rotationally fixed manner to the movable clamping jaw.
  • a spring-loaded pawl that swivels in the housing engages in the ratchet wheel in the latched position.
  • the disadvantage of this device is its complicated structure and the fact that two different levers have to be actuated for opening and closing the clamping pliers.
  • a corresponding device in accordance with EP-OS 241 631, in which a helical spring lock is provided instead of a jack coupling, is no less complex with regard to construction and operation.
  • the present invention has for its object to provide a clamp for chain transporters of the type mentioned, in which the locking of the movable jaw - in its closed position and its opening is carried out by a simple mechanism without additional springs, actuating levers and other complicated parts.
  • clamping pliers according to the invention have the advantage that the closing force of the resilient force transmission element connecting the lever to the movable clamping jaw after the dead center of the pivoting lever has been overcome, the lever in its closed position of the movable one
  • Clamping jaw holds the appropriate end position.
  • a dead center mechanism for the lever requires only a few simple elements, for example a separate shaft for the lever and a knee joint or a locking curve in connection with the lever.
  • FIG. 1 shows a plan view of a first embodiment of the clamping tongs according to the invention with a knee joint, the clamping tongs being shown in their closed position;
  • Fig. 2 is a side view, partially in section, the

  • FIG. 6 shows a side view of the clamping pliers of FIG. 4 in their closed position according to FIG. 1.
  • the clamping pliers shown have a substantially rectangular, box-shaped and upwardly open housing 1 made of a plastic.
  • the clamping pliers have a clamping jaw 4 fastened to the housing base 2 with screws 3, a pivotably movable clamping jaw 5 and an actuating lever 6.
  • the plate-shaped jaws 4 and 5 are shown interrupted in Fig. 1 for clarity.
  • the screws 3 can at the same time also serve to fasten the clamping pliers on a chain conveyor (not shown).
  • the lever 6 is provided with a roller 7 for its actuation by an external organ.
  • the lever 6 is pivotally mounted on a shaft 8 arranged in the housing 1, specifically in a corner cutout 9 of the housing 1 (FIG. 1).
  • the lever 6 is formed with two arms and has on its lever arm 10 opposite the roller 7 a shoulder 11 which comes to rest on the inside of the base 2 in the closed position of the clamping pliers (FIG. 3) and thus the pivoting movement of the Lever 6 limited around the shaft 8 in one pivoting direction.
  • the lever arm 10 is provided with a lug 12 having a bore.
  • a bearing pin 13 is also arranged parallel to the shaft 8.
  • the bearing pin 13 carries a first, on this rotatable sleeve part 14 and, axially separated from the sleeve part 14, a second, on the bearing pin 13 rotatable sleeve part 15.
  • the two independently rotatable sleeve parts 14 and 15 are by a coaxial coil spring 16 (Fig. 1st ) connected to each other, the helical spring 16 being inserted at one end 17 into a nose 18 of the second sleeve part 15 and at its other end 19 (FIG. 1) into the first sleeve part 14.
  • a second coaxial coil spring 20 is arranged as a return spring, which is inserted at one end 21 into a side wall 22 of the housing 1 and at its other end 23 into a nose 24 of the first sleeve part 14.
  • the movable clamping jaw 5 is firmly anchored to a projection 25 of the first sleeve part 14 (FIGS. 2, 3) by means of screws 26 (FIG. 2). It is thus on the bearing pin 13 against the force of the helical spring 20 from the open position according to FIG. 2 to the closed position according to FIG.
  • Fig. 3 pivotable.
  • the open position of the jaw 5 is limited in that the jaw 5 comes to rest on an upper housing edge 27 (FIGS. 2, 3).
  • the lever 6 is with the second sleeve part 15 via a
  • the nose 12 of the lever arm 10 is rotatably mounted in a slot 29 of the tab 28 by means of a bolt 30.
  • the other end of the tab 28 is supported in a slot 31 in the nose 18 of the second sleeve part 15 by means of the end 17 of the helical spring 16.
  • a rotary movement of the lever 6 thus causes a rotation of the second sleeve part 15 or a rotary movement of the helical spring 16 via the tab 28.
  • the return spring 20 acts from the first sleeve part 14 via the first coil spring 16 and via the tab 28 also on the lever 6 and holds it in the position shown in FIG. 2.
  • the coil spring 16 is to be regarded as a quasi-rigid connection between the first sleeve part 14 and the lever 6.
  • the movable jaw 5 encounters a substantially fixed obstacle during its pivoting movement, which, according to FIG. 3, either the fixed jaw 4 or an object lying between the fixed and the movable jaw 4 or 5, for example a folded object
  • the lever 6 is pivoted in a simple manner in the opposite direction to the arrow 32, the helical spring 16 first opening the movable clamping jaw 5 and pressing the lever 6 downward and including the return spring 20 for a complete opening the pivoting of the lever 6 in its position according to FIG. 2.
  • FIGS. 4 to 6 The further embodiment of the clamping pliers according to the invention shown in FIGS. 4 to 6 makes use of another dead center mechanism, namely a locking curve instead of a knee joint.
  • the clamping pliers in turn have an approximately rectangular, box-shaped housing 41 with a housing base 42, to which a clamping jaw 44, shown broken off in FIG. 4, is fastened by means of screws 43.
  • a pivotably movable jaw 45 the design and arrangement of which will be explained in the following, is designed in the form of a wire. det.
  • the clamping pliers again have a lever 46 for their actuation, which is provided with a roller 47.
  • the lever 46 is connected to a first shaft 48 which is rotatably mounted in the housing 41 and which is subjected to the force of a coaxial restoring spring 49 which is supported on the housing base 42 and which thus shows the lever 46 in the position shown in FIG. 5 Position presses against a housing stop 50.
  • a second shaft 51 which is designed as a hollow shaft and, like the housing 41, is made of plastic, is rotatably mounted.
  • the shaft 51 is provided in the interior of the housing 41 with a longitudinal slot 52.
  • the shaft 51 projects beyond it and is provided with an integrally formed lever arm 53.
  • the lever arm 53 has a straight longitudinal groove 54 which is open at the radially outer end and has a sharp-angled bend 55 in its radially outer end region and a curvature 56 on the other side (FIGS. 5, 6).
  • the lever 46 is provided on its side opposite the groove 54 with a roller 57 which is guided in the groove 54. A pivoting movement of the lever 46 thus causes the shaft 51 to rotate.
  • the wire-shaped, movable clamping jaw 45 is wound inside the housing 41 with its two side parts 58 and 59 around the shaft 51 and with its ends 60 and 61 in the slot 52 of the shaft 51 inserted.
  • the winding sections of the movable clamping jaw 45 thus each form a helical spring 62 or 63, which connect the clamping jaw 45 to the lever 46 via the shaft 51 and the lever arm 53.
  • the operation of the clamping pliers shown is explained as follows with reference to FIGS. 5, 6. 5, the return spring 49 presses the lever 46 against the housing stop 50.
  • the jaw 45 is held in the open position shown via the roller 57, the groove 54 of the lever arm 53 and the shaft 51 because there is no a resistance of the jaw 45, the helical springs 62, 63 form a quasi-rigid connection of the lever 46 to the jaw 45.
  • An obstacle namely the fixed jaw 44 or an object such as a newspaper or the like, which is not shown in FIGS. 5 and 6 and is located between the two jaws 44, 45, becomes when the lever 46 is pivoted further the two in the direction of arrow 64
  • Coil springs 62 and 63 tensioned.
  • the clamping jaw 45 exerts a corresponding clamping force on the one hand, while on the other hand the same force tends to reset the lever 46.

Abstract

Une pince-étau comporte un carter (1) qui peut être relié au transporteur à chaîne et dans lequel sont disposées une mâchoire de serrage (4) solidaire du carter et une mâchoire de serrage (5) montée pivotante qui peut être déplacée depuis une position ouverte vers la mâchoire (4) solidaire du carter. Un levier (6) monté dans le carter (1) peut pivoter entre deux positions terminales qui correspondent aux positions ouverte et fermée, respectivement, de la mâchoire mobile (5), par rapport à la mâchoire (4) solidaire du carter. Le levier (6) est relié à la mâchoire mobile (5) via un élément de transmission élastique (16) dont l'élasticité oppose un mouvement relatif entre la mâchoire mobile (5) et le levier (6) lors de leurs mouvements de fermeture. Pour fermer et ouvrir la mâchoire mobile (5), le levier (6) pivote entre ses deux positions terminales en passant par le point mort d'un mécanisme de point mort (12, 18) disposé entre le levier (6) et l'élément de transmission élastique (16).
