Definitions

  • the invention relates to a shipping system of the type specified in the preamble of claim 1.
  • Such containers with a conical core which can be produced by winding on a conical winding core to form a truncated cone shaped like a truncated cone, are used in the wire and cable industry, since they have a relatively high intrinsic stability in regular continuous unwinding in a single position and during unwinding electrical line or the cable of the outer winding layer has a certain intrinsic stability due to the conical shape and the outer winding layer - and thus the entire container - does not collapse prematurely.
  • these containers are provided with a foil covering and / or with drawstrings at least on their tangential outer surface.
  • a disadvantage of the known containers is that an already partially unwound winding body which is to be transported inevitably deforms and collapses. As a result, it can then usually no longer be economically reshaped into a developable state using conventional devices. The remaining roll is usually lost when it is no longer possible to bring the remaining roll into a developable configuration and then to keep it in such a configuration.
  • a device for producing such packages on bobbins with a flange on one side is known from EP-A 0 398 682.
  • the known winding devices consist of a rotatable table on which conical winding cores are fixed. During winding, an upper guide plate is lowered onto the winding core and the material to be wound is wound into a winding body on the conical part of the winding core. After removing the guide plate, the winding body is removed from the winding core and is thus ready for dispatch.
  • the invention has for its object to provide a shipping system for a container of the type mentioned, in which the winding body can be transported safely but also an opened residual package always takes a stable arrangement and is therefore easy to implement.
  • the invention is based on the knowledge that a stable, transportable container is formed if, during the assembly, the conical winding core, on which the winding material has been wound into a winding body, does not remain with the winding device, but is removed and shipped together with the winding body from the winding device becomes.
  • the circumference of the winding body and Parts of the winding core are enclosed in a film wrapper before shipping.
  • This enclosing film covering is produced from a shrink tube, which is placed around the circumference of the winding body and shrinks when heated, so that it lies against the winding body and the winding core.
  • plastic fabric tapes are placed around the winding former and the winding core before the film wrapping, the ends of the tapes then being connected to one another by means of friction welding. Since the winding core according to the invention is widened like a flange at the lower end, the winding body not only lies against the conical part of the winding core but also sits on this flange-like widening.
  • the packaging device consists of the actual winding device and a downstream packaging device.
  • the winding device consists of a rotating table on which at least one winding core, which is then also rotatably mounted, can be placed. When the table rotates, the winding cores placed on the table are then positioned one after the other under the actual winding station of the winding device. In a further development of the winding device, it has a plurality of winding stations, so that a plurality of winding bodies can be produced simultaneously. An end plate is placed on the winding core before it is wound with material to be wound and coupled axially to the winding core.
  • the end plate can either be part of each winding station or can also be from a separate coupling device, through which the winding core passes before reaching the winding station, are placed on the winding core. If the end plate is part of a winding station, it can either be rotatably mounted but firmly connected to it, or it can be completely separated from the winding station. Then the winding follows, the material being wound being wound onto the winding core in a known manner. The end plate is then uncoupled from the winding core and raised. This can in turn either take place at the winding station itself or is carried out by a separate decoupling device through which the winding core passes after the winding.
  • the winding device has a further transport device with which the end plates are returned from the decoupling device to the coupling device in the sense of a circulation.
  • the winding core is then removed from the table at a removal station by the winding device.
  • the winding core having the winding body is then fed to the packaging device, which consists of a holder for the conical winding core, a binding device, a gripping device and a film feed device.
  • the winding core having the winding body is placed on a corresponding receiving holder, which is conically tapering and is designed in accordance with the inner cone of the winding core.
  • the receptacle holder is designed as a hollow cone slotted in the longitudinal direction, so that the plastic fabric tapes which the binding device around the winding core having winding core can be inserted from above into the hollow cone and from there can be bound around the winding body in the area of the slots.
  • the winding body bound in this way is then passed on to the film feed device, in which the film, which is used for the ready-to-ship packaging by the winding core having the winding body, is stored.
  • a gripping device takes the lower end of the film out of the film feeding device and leads it to the winding body, which is seated on the receiving holder.
  • the film is advantageously designed as a shrink film tube and the gripping device spreads the shrink film tube in order to put it over the winding core.
  • the shrink film tube is then cut off above the winding core and the shrink film tube shrinks when heat is applied and lies against the circumference of the winding body and at least partially against the winding core.
  • the end plate which can be completely separated from the winding station or from the coupling device and which serves to guide the winding material during winding is axially coupled to the winding core.
  • the winding core has an essentially circular opening at the upper end, which is provided with at least two opposite winding core approaches that reduce the opening radius.
  • the end plate which has an extension, the radius of which corresponds to the reduced opening radius of the opening in the winding core and with at least two end plate extensions, which are arranged opposite one another at the edge of the attachment, can be inserted into the upper opening of the winding core in the manner of a bayonet lock.
  • the rotatably mounted but firmly connected to the winding station end plate in contrast, has only a pin-shaped projection, the shape of which corresponds to the shape of the opening at the upper end of the winding core.
  • a closure plate which is connected to a flange-like guide plate for guiding the winding material during unwinding, can be placed on the winding core by means of a bayonet coupling.
  • the closure plate attachments are positioned like a bayonet lock under the reducing winding core approaches of the winding core opening.
  • the guide plate connected to the closure plate is designed in this way is that it has a diameter that is larger than the winding body diameter and because its underside lies on the winding core and thus on the winding body, the winding body arrangement is stable even after tearing open the film wrapping, since the winding body is now between the flange-like lower widening of the Winding core and the guide plate is clamped.
  • closure plate and the guide plate both have at least two bores arranged in a ring around their central axes, the arrangement of which corresponds to one another and in which a device for locking the two plates together is introduced.
  • the bores are provided with a thread and the locking device is designed as a screw which is resiliently supported on the guide plate and can be screwed into the bores.
  • the locking plate lugs which are positioned like a bayonet lock under the reducing winding core lugs, are always in contact with the winding core lugs due to the spring-loaded locking screw and thus form a locking mechanism that can no longer accidentally move in the radial direction.
  • the closure plate can also have a central bore to reduce weight, such a closure plate then being able to be inserted into the winding core with a telescoping bracket.
  • winding core is made of a thin-walled plastic, this is the case made sure that the packaging portion of the goods is kept as low as possible during shipping.
  • the winding cores which can be stacked easily when empty due to their hollow conical shape, form a small volume of return freight.
  • the winding core has at least two web-like ribs on its inner surface, which are located radially opposite one another and extend in the direction of the longitudinal axis of the winding core.
  • the ribs increase to a maximum height, which, however, never exceeds the maximum width of the reducing winding core approach, so that the ribs are always covered by the winding core approaches.
  • These ribs increase the inherent stability and the torsional rigidity of the winding core.
  • when stacking some winding cores on top of each other they are suitable as spacers in which a winding core that has been put on cannot be placed entirely on the lower winding core.
  • the attached winding core lies with the lower end face of its raised ribs on the upper end face of the other winding core.
  • the shipping system that has arrived at the place of use is easier to implement, since the lifting plate in the preferred embodiment has a centrally arranged eyelet as a connection for a lifting device has, which is either arranged fixedly on the lifting plate or can be firmly connected to it. In addition, it is designed with approaches that engage the ribs to further increase the stability of the lifting plate used.
  • the shipping system according to the invention has an unwinding hood which is dimensioned such that it can be placed over the winding core with the guide plate attached.
  • the unwinding hood is provided with at least one upper opening with rounded edges.
  • the opening is preferably designed as a ball bearing, the inner ring of the ball bearing having rounded edges with the largest possible radii.
  • the flange-like extension of an advantageously further developed winding core has an annular groove in the edge region.
  • the lower, ring-shaped edge of the unwinding hood can be inserted into this groove.
  • the unit consisting of the winding core, container, guide plate and unwinding hood is easy to implement.
  • the shipping system according to the invention also includes a movable base. This is formed in its preferred embodiment as a rollable base, the external dimensions of which correspond approximately to the lower flange-like extension and is provided with bolts. These bolts are inserted into the bores of the lower flange-like extension when the winding core is placed on the base and thus ensure that the winding core is mounted on the base in a manner that prevents rotation.
