Definitions

  • the invention relates to a device for receiving and unrolling rolls made of strip-shaped or wire-shaped material (coil) according to the preamble of claim 1.
  • Cassettes and manipulators for rolls made of strip-shaped or wire-shaped material are known and used in a wide variety of embodiments.
  • Known coil cassettes are usually designed for "just-in-time" production, i.e. a coil is stored in the cassette, on a processing machine, e.g. promoted a press; there part of the wound tape or wire is drawn off; the cassette with the partially used or unwound coil is then brought back into a storage rack.
  • Such coils and storage methods for coils are e.g. known from the following publications: DE-AS 2842448, DE-OS-3435215, 3417130, 2639427 and EP-A1-267357.
  • cassettes with unwinding and storage devices e.g. are designed for vertical storage and also for pulling off the strip material, they must be of stable construction in accordance with the task.
  • the space required for such cassettes is correspondingly large, the cassettes are complex and expensive to manufacture.
  • the cassettes mostly follow the outer configuration of the coil, i.e. they are round and therefore difficult to manipulate and store.
  • the object of the invention is to improve the previous disadvantages, in particular to create an inexpensive, simple system which improves the storage and handling options for coils, and above all the automation of storage and handling is facilitated. According to the invention, this is achieved by a device with the features described in the characterizing part of claim 1.
  • the coil can simply be stored in the trough or removed from the trough.
  • the coil can be raised in the tub for rolling and stored on a separate roller or bearing arrangement while the strip material is being pulled off the coil, without the coil having to be removed from the base element.
  • Sufficient static strength can be achieved in a simple manner by a stiffening arrangement in the edge region of the floor element. This makes it possible, for example, for the receiving device to be pushed onto a rail-like support which engages the stiffening arrangement on both sides. This can save space, e.g. be stored on a shelf with support rails arranged vertically one above the other.
  • this stiffening arrangement is designed as a frame, tie straps can be fastened to it, preferably diagonally and on the surface of the frame, which serve to hold the coil. This achieves an extremely low weight with sufficient stability for the cassette.
  • support elements should preferably be provided. That comes on their flat surface Coil itself or a coil support disc lying in between, while the underside of these support elements, which are designed in particular in the form of a U-profile, is adapted accordingly to the sag of the drawstrings. This can also be achieved by suitably shaped insert wedges that fit into the U-profile of the support elements.
  • this latter embodiment has the great advantage that the pick-up device can be used in the same way for coils with different bandwidths.
  • a centering device for the coil is provided in the base element.
  • the centering device can be designed such that it contributes to stiffening the base element. This is particularly simple if the centering device is designed, for example, as a raised edge or as a bead.
  • the centering device is provided in the middle thereof, preferably having a raised, bead-shaped edge with which it engages in the inside diameter of the coil, and - for unrolling the coil - the allows centering insertion of a dome.
  • the centering device can, however, not only be provided on the receiving device itself, but can also be introduced into it, for example for unrolling, through an opening in the floor or from above such that the coil is supported in the center when unrolling. In this way it can be achieved that the receiving device itself is not stressed by the tensile forces occurring when the strip-like material is unrolled or pulled off.
  • an opening is provided in a simple manner in the base element or in the center of the drawstrings and the support elements, through which an opening
  • the mandrel can be inserted in such a way that the mandrel lies in the center of the coil and supports it when pulling off or unrolling, which is of particular interest when the coil is unwinding vertically.
  • the centering device for the coil is therefore conceivable in different ways, be it as a mandrel, bead, bead or bush in the base element or the coil support disk, or as a mandrel engaging therein or simply in a central opening, or also as a combination of two or more of the elements mentioned.
  • a particularly high rigidity of the floor element - and this in a simple manner - is achieved by designing the reinforcement arrangement as a laterally raised edge of the floor element and / or as a stiffening of the beads in the floor area.
  • the bottom element can be relieved of all tensile and bearing forces in an advantageously simple manner if openings are provided in it, through which suitable elements for lifting the coil act when inserting, removing or rolling off the coil or on its support disk.
  • openings are three or four radially running slots through which rollers or rollers can be introduced from below.
  • this penetration of rollers or rollers is even easier, namely in the free spaces between the drawstrings.
  • a mandrel can also be provided as the holding element, which passes through an opening in the middle of the base element, possibly spreads in the inside diameter of the coil, and thereby raises the coil and rotatably supports it. So that the mandrel can be inserted into the center of the centering device as easily as possible, this centering device is advantageously provided to be radially displaceable, this displaceability being given relative to the base element of the cassette or the coil support disc.
  • stiffening arrangement is designed as a laterally raised edge, a slot or, in order to remain independent of the bandwidth of the coil, an upwardly open gap for the passage of the band-shaped or wire-shaped material in the side wall of the base element is advantageously provided.
  • a securing bracket should be attached, preferably around the outside diameter of the coil, in order to prevent the generally relatively stiff coil strips from springing open is arranged and in turn has a slot or open gap for the passage of the coil strip.
  • securing brackets are advantageous which prevent the coil band from jamming between the openings of the base element and the rollers.
  • a strip clamping device should be provided.
  • the band is clamped between two clamping jaws, which are moved relative to one another via a toggle lever system, which is preferably articulated on the stiffening arrangement.
  • this strip clamping device When lifting the coil, in order to avoid deformation of the coil strip, this strip clamping device must also be lifted. This is possible in a simple manner if it is attached to the stiffening arrangement. It can then be lifted up together with the coil using specially provided brackets. As shown above, rollers or rollers can be used for lifting and also unrolling the coil.
  • the receiving device according to the invention is particularly advantageously suitable for horizontal storage and manipulation, applications are also conceivable in which the receiving device is erected vertically together with the coil and pushed onto a horizontal winding mandrel.
  • a controlled hold-down device can be used which supports the coil during erection, manipulation and processing.
  • the floor element used can be rationally manufactured from metal using the bending, drawing-welding technique or in a combined manufacturing process; it can also be made of plastic, e.g. using injection molding technology.
