Definitions
- the invention relates to a clamp for an end los f örde re r according to the preamble of claims 1 and 4.
- EP 03 86 442 A2 discloses a generic clamping pliers for end-to-end conveying, in which a first fixed jaw is arranged from an open position against the first jaw and is pivotally mounted second jaw.
- the pivotable jaw is arranged on a first lever arm of a three-armed lever.
- An actuating roller for actuating the clamping jaw in its open and closed position is mounted on a second lever arm.
- a third lever arm is designed as part of a device for introducing a clamping force, this device overcoming a dead center when the clamping jaw is actuated.
- the invention has for its object to provide a clamp for End los f örde re r.
- Clamping jaw in the closed position acts on the jammed printed product.
- the clamp is designed without a housing.
- Each clamp has a base, which forms a stop for the products to be picked up. This stop ensures a gentle pick-up as well as an error-free delivery of the product to be transported.
- a simple, component-conserving force curve design is achieved in that an additional in a lever carrying the jaw
- Fig. 1 is a schematic representation of a
- Figure 2 is a schematic representation of the side view of the clamp in the closed position.
- Fig. 3 is a representation analogous to FIG. 2, but with a variant of the actuating lever.
- a pair of pliers 1 for an end downstream of a rotary printing press, for example, for. 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.
- the carrier 3 of the first jaw 4 is z. B. L-shaped.
- 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 arranged parallel to the longitudinal axis 9 of the chain link 2.
- An outer end 11 of the long leg 8 is V-shaped and connected to the first jaw 4.
- a jaw base 10 formed in this way has a radius r10.
- the radius r10 is larger than a radius of a front edge 12 of a good transported by means of the clamp 1, e.g. B. a printed product 13 (Fig. 2).
- the carrier 3 has a bore 14 running at right angles to the longitudinal axis 9 of the chain link 2.
- this bore 14 is a pivot axis 16 of a lever
- the lever 17 has a first lever arm
- the first lever arm 18 is provided at its extended, free end with a roller 19 for actuating the lever 17.
- the second lever arm 22 has at its end a bearing pin 23, which serves as a force application point 24 for one end of a tension spring 26 designed as a force-feeding device.
- the tension spring 26 has at its other end an abutment 27 which is operatively connected to a bearing pin 28 located at the end 11 of the long leg 8.
- the carrier 3, which is L-shaped in cross section extends in a direction parallel to the pivot axis 16.
- the carrier 3 has at least the width of a chain link 2.
- the first jaw 4 located on the carrier 3 is wider, e.g. B. twice as wide as the inertia r 3.
- the lever 17 can be arranged on the pivot axis 16 on both sides of the carrier 3 and connected by means of the second clamping jaw 6.
- two tension springs 26 are also used and each of the two first lever arms 18 carries a roller 19.
- the second clamping jaw 6 can be provided with a radius at its end acting against the inside of the first clamping jaw 4. This avoids undesired embossing on the printed product 13.
- a distance a1 between the end of the jaw 6, i. H. the contact zone of the printed product 13, and the pivot axis 16 of the clamping jaw 6 is preferably somewhat larger than the shortest distance between the pivot axis 16 and the inside of the clamping 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.
- This includes 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 one Contact zone of the printed product 13 and the clamping jaw 4 created tangent 34 an opening angle alpha.
- this opening angle alpha is referred to below as the opening angle enclosed by the two clamping jaws 4, 6.
- This opening angle alpha which is necessary for self-locking pointing away from the clamping jaw base 10, depends on the coefficient of friction between the clamping jaws 4, 6 and the printed product 13 and is greater than 45 °, preferably greater than 60 °, and less than 90 °. Thus, 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).
- a loading station e.g. B. a paddle wheel of a folder
- a printed product 13 is guided between the jaws 4, 6.
- 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 a dead center position B coming, 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 the open and closed position A, C of the second clamping jaw 6 are achieved in that a distance between the force application point 24 and the abutment 27 of the tension spring 26 in the open and closed position A, C is smaller than the length of the dead point st rec ke , d. H. of this distance in dead center position B.
- the clamping jaw 6 is thus held in the open and closed position and finally by the power supply rather 26, d. H. without permanent influences e.g. B. a curve control.
- the thickness of the printed product 13 can lie between 0.1 mm and several millimeters.
- a further roller 31 is assigned to the first lever arm 18 of a lever 32.
- This roller 31 is arranged between the first roller 19 and the jaw 6.
- the arrangement of a roller 31 which is additional to the roller 19 is advantageous in that the switching of the second clamping jaw 6 into the end position A, C can be carried out via different rollers 19, 31.
- lever 17, 31 having two lever arms
- only a single lever arm can also be provided.
- the adjustable clamping jaw 6 is then attached to this single lever arm and the actuating forces for the movement of the clamping jaw 6 into its open and closed positions as well as the clamping forces are introduced.
