Definitions

  • the invention relates to a device for clamping the partial strips of a strip longitudinally divided in a splitting system, consisting of two clamping jaws and pressure means acting on them.
  • the invention has for its object to provide a device of the type mentioned, with which the required spreading of the partial strips can be carried out better than by hand.
  • At least one of the clamping jaws consists of a plurality of clamping stones arranged next to one another in series, which can be expanded by a thrust crank or wedge mechanism acted upon by the pressure means.
  • the device according to the invention it is possible to detect the partial strips directly at the exit of the scissors. This ensures that the partial strips with respect their position can be precisely grasped. Since the spreading takes place when the partial strips are clamped in, it is also ensured that the new position of the partial strips on the take-up reel is reached very precisely. The entire distance between the shear and the reel is available for the spreading process. The spreading process can therefore take place at a point where the partial strips can be easily separated.
  • the construction of the device is low, since both the clamping force and the force required for the expansion process are applied and transmitted with the same pressure medium.
  • the thrust crank mechanism consists of one or more articulated chains, of which each chain link is articulated to a clamping block with its first articulation point and is articulated on the back of the clamping jaw with its second articulation point to the second articulation point of the next chain link, the pressure means acting on the second articulation points.
  • the chain links of the two articulated chains preferably cross, whereby they are connected to one another in an articulated manner at the crossing points (parallel crank mechanism).
  • the second articulation points carry freely rotatable rollers on articulation pins, on which the pressure means engage. Rollers can also be assigned to the pressure means, each of which engages at two adjacent articulation points. Alternatively, wedges can be assigned to the pressure means, the wedge surfaces of which on two adjacent second ones Attack articulation points.
  • rollers on the hinge pin and / or of wedges or rollers has the advantage that the friction between the pressure media and the chain is reduced and the force components are introduced more cheaply.
  • Friction reducing also has an effect if the wedges or rollers are supported on a slide or roller track of the pressure medium.
  • the traction means can be an elastic drawstring fastened to the clamping stones.
  • both clamping jaws have the same structure, the individual clamping stones being arranged opposite one another as pairs.
  • the splitting system has a decoiler 1 with coiled tape 2, a decoiler 3 with a receiving slot 4, a pair of scissors 5 in the form of several pairs of circular knives, a brake 8 which can be moved apart in the form of a pair of rollers and a device 7 for clamping, spreading, transporting and pushing in the partial strips 6 of the slit band 2.
  • the device 7 for clamping can be moved between the scissors 5 (FIG. 1) and the reel 3 (FIG. 2). Trolleys known per se can be used to move the device 7.
  • the partial strips 6 emerging from the scissors 5 are gripped by the clamping device 7, so that the front Project ends 6 '.
  • the partial strips are then clamped and moved by the device 7 in the direction of the reel 3. In doing so, they are spread, that is, placed at a mutual distance.
  • the device 7 pushes the partial strips 6 into the receiving slot 4 of the reel, where they are fastened. Then the winding process can begin.
  • the device 7 is retracted and the brake is brought into the functional position so that the individual partial strips 6 can be wound onto the reel 3 to form bundles 9 with a lateral spacing.
  • the clamping device 7 carries two clamping jaws 10, 11 in a housing, which form a passage gap 12 for the partial strips 6 between them.
  • the structure of the jaws 10, 11 is the same, with the exception that the lower jaw can be moved against the other jaws 11 by a pressure medium in the form of a bellows 13 which can be filled with a pressure medium.
  • the further description of the jaws 10, 11 can therefore be referred to Limit description of the jaw 10.
  • the clamping jaws consist of a plurality of clamping stones 14 arranged next to one another, which are connected to one another via the links of an articulated chain 15 in such a way that the first common articulation point 16 of two adjacent articulated links 17, 18 act on the clamping stone 14, while the second articulation points 19, 20 of the chain links coincide with the second articulation points of the adjacent chain links 21, 22.
  • These second pivot points 19, 20 are supported on a roller conveyor 23.
  • the first and second hinge points 17, 18, 19 are formed by hinge pins.
  • the hinge pins of the first hinge points 16 are fastened in lateral legs 24 of the clamping stones 14 which are U-shaped in cross section, while the hinge pins of the second hinge points 18, 19 carry freely rotatable rollers 25, 26 which interact with the roller conveyor 23.
  • the hinge pins of the first hinge points can also carry rollers, as is generally the case with a hinge chain and is also shown in the drawing, but these have no function in the exemplary embodiment.
  • the clamping blocks 14 and the articulated chain 15 with the articulated bolts are designed such that they are guided in a guide body 27, as shown in FIG. 5.
  • the clamping stones 14 are pretensioned by a pressure medium 28 which acts in the longitudinal direction of the clamping jaw 10 and which acts on the outer clamping stone with a stamp 29.
  • the push crank mechanism in the form of the articulated chain 15 becomes effective.
  • the chain links 17, 18 attempt to evade the further pressurization by adopting a more and more stretched position and thereby placing the clamping stones 14 at a mutual distance, as shown in FIG. 6.
  • the force of the pressure medium 28 must of course also be overcome. So that the spreading process is not initiated immediately, but only the clamping force is initially applied, it is necessary that the pressure medium 28 acting as an abutment is able to absorb the reaction force.
  • FIGS. 8 and 9 differs from the described embodiment only in that the rollers on the hinge pin do not roll directly on the roller tracks, but that free roller bodies 30 are arranged between the rollers.
  • the free rollers 30 penetrating into the gusset between two rollers arranged on bearing pins, the chain links and thus also the clamping stones are brought at a mutual distance. Due to the wedge effect of the free rollers 30, the spreading process is facilitated.
  • FIGS. 10 to 13 differs from that of FIGS. 4 to 7 in that two link chains are assigned to each clamping jaw, the crossing chain links of the two link chains being articulated to one another at their crossing points 31. With two link chains, the chain links are arranged less steeply than with a link chain. This is advantageous for the spreading process and for the guidance.
  • FIGS. 14 and 15 differs significantly from that of the previously described embodiments. It shows a device for clamping with a wedge gear. Instead of the chain links of the previous exemplary embodiments, free roller bodies 32 are provided which lie in the gusset of wedge surfaces 33, 34 of adjacent clamping blocks 35, 36 and are supported on rollers 37 which, like the rollers 25, 26 or 30, are assigned a roller conveyor 38. Otherwise, this embodiment corresponds to the described embodiments.
