Definitions

  • the present invention relates to a device and a method for forming a multi-part strip coil from a plurality of individual strip coils according to the independent claims.
  • a multi-part strip coil includes, for example, what is known as a PUP coil ("piece under piece coil"), which is so called because the individual strip coils in the PUP coil are arranged one inside the other, for example nested inside one another.
  • a multi-part strip coil formed with the device according to the invention for example a PUP coil, is formed, among other things, in coil-processing plants from smaller strip coils, which occur, for example, as cutting residues when processing large strip coils. These multi-part strip coils are then fed into other manufacturing processes. For this purpose, they are often packaged and sent to other companies for further processing.
  • FR'296 and US'557 disclose reels which can rotatably mount a strip coil in the coil eye via a spreadable mandrel.
  • US'688 and FR'991 disclose devices for cutting and winding strip material. The object of the present invention is to make the forming of a multi-part strip coil simpler, faster and safer.
  • the invention solves this problem with the features in the characterizing part of the independent device claim.
  • the device in this case has a untwisting unit, wherein a strip coil with its Bandcoilinnenseite can be positioned around the untwisting unit, wherein the device is set up to a bring about relative rotation between the untwisting unit and a strip coil, and the untwisting unit can exert a radially directed compressive force against a strip coil inside during a relative rotation between the untwisting unit and the strip coil.
  • the untwisting unit which can exert a radially directed compressive force against the inside of a strip coil during relative rotation between the untwisting unit and the strip coil, makes it possible to increase the inner diameter of strip coils by untwisting the strip coils expand and thereby create space for positioning further strip coils between the untwisting unit and the inside of the enlarged strip coils.
  • the compressive force during rotation against the inside of a strip coil allows the untwisting unit to untwist a strip coil, since the strip coil to be untwisted experiences both a radial force and a rotational force due to the friction between the untwisting unit and the inside of the strip coil.
  • the device according to the invention has a limiting structure which is arranged in the radial direction in relation to the untwisting unit and against which the untwisting unit can press a strip coil from the inside of the strip coil.
  • This limiting structure makes it possible to create a defined stop for the radially outermost strip coil of the multi-part strip coil to be formed.
  • the restraining structure can thus decelerate or hold stationary the outermost coil of tape, thus facilitating untwisting.
  • the delimiting structure allows a pressing compression of the individual strip coils of the multi-part strip coil.
  • the delimiting structure can enclose the untwisting unit in the radial direction.
  • a defined stop can thus be created for several points on the outermost strip coil.
  • the outer dimensions, for example the outer diameter, of the multi-part strip coil to be formed can thus be easily defined.
  • the untwisting unit can have an axis of rotation and the untwisting unit can be set up to rotate in different radii around the axis of rotation and to exert a radially directed compressive force against an inner side of the strip coil as the radius increases.
  • the untwisting unit can be of columnar design in a basic position, in particular tapered at a free end.
  • the untwisting unit can be aligned with its axis of rotation vertically.
  • a strip coil positioned around the untwisting unit is also positioned with its coil eye vertically upwards and can thus be untwisted very evenly and easily radially in the horizontal direction.
  • the untwisting unit can have a force and movement conversion mechanism, which converts a force and/or movement introduced in the untwisting unit in the direction of the axis of rotation into a radial compressive force and/or movement of the untwisting unit.
  • a force and movement conversion mechanism which converts a force and/or movement introduced in the untwisting unit in the direction of the axis of rotation into a radial compressive force and/or movement of the untwisting unit.
  • the force and movement conversion mechanism can have a linear actuator acting in the direction of the axis of rotation and a radially acting scissor mechanism. This combination allows a particularly compact, for example columnar, and reliable design of the untwisting unit.
  • the untwisting unit can have at least one extendable arm for pressing against an inner side of a strip coil, in particular at least one extendable and rotatable arm.
  • Such an embodiment enables a controllable pressing against an inside of the strip coil.
  • An optional extendable and rotatable design of the boom also allows the boom to simultaneously apply a compressive force and a rotational force against the inside of a strip coil.
  • the at least one cantilever can have a shield at its free end, which is set up to press against the inside of a strip coil and to slide along the inside of a strip coil with friction during rotation.
  • the shield advantageously allows a flat pressing against the inside of the strip coil while at the same time applying a rotational force against the inside of the strip coil.
  • a first end of the scissor mechanism on the rotation axis side can be articulated in a stationary manner and a second, movable end of the scissor mechanism on the rotation axis side can be articulated on the linear actuator, and two ends of the scissor mechanism facing away from the axis of rotation can be articulated on the shield, wherein one of the ends on the shield side can be articulated on the shield so as to be displaceable in the direction of the axis of rotation.
  • linear actuator advantageously combines the advantages and functions previously mentioned in connection with these features. Furthermore, such an arrangement enables, for example, when a constant force is introduced into the linear actuator, the compressive force of the cantilever against the inner side of the strip coil increases with increasing radius.
  • the untwisting unit can have a plurality of extendable, preferably also rotatable, arms which are arranged in the circumferential direction around the axis of rotation of the untwisting unit, in particular at equal distances from one another in the circumferential direction.
  • the delimiting structure can be reversibly detachable from the device.
  • the delimiting structure can advantageously be designed as part of a detachable coil transport means, in particular as a side wall of a detachable coil transport container.
  • the untwisting unit can protrude through a through-hole of the detachable coil transport means, in particular the Coil transport containers have a bottom and a side wall, and the untwisting unit protrudes into the coil transport container through a through-hole in the bottom of the coil transport container.
  • This special arrangement between the untwisting unit and the coil transport means makes it easy to shape the multi-part strip coil on the coil transport means.
  • the special, optional design between the unwinding unit and a coil transport container is particularly advantageous here.
  • the coil transport container can be open at the top. This allows easy introduction of the individual strip coils into the coil transport container and thus into the device, and also later easy lifting of the formed multi-part strip coil out of the coil transport container.
  • the coil transport container can be opened and closed laterally. This allows easy side access to the formed multi-piece strip coil, for example with a forklift.
  • a removable transport pallet with a through hole can be provided on the bottom of the coil transport container, and the through hole in the transport pallet and the through hole in the coil transport container are aligned with the axis of rotation of the twisting unit and can be dimensioned in such a way that the coil transport container together with the transport pallet are in the direction of the axis of rotation is detachable from the rest of the device.
  • This arrangement enables simple and reliable forming of a multi-part strip coil lying on a transport pallet in a coil transport container, with the multi-part strip coil already being particularly advantageously prepared for subsequent processing and transport steps.
  • Method for forming a multi-part strip coil from a number of individual strip coils characterized by positioning at least one strip coil with its inside around a untwisting unit, rotating the untwisting unit and the at least one strip coil relative to one another, pressing the untwisting unit against the inside of the at least a strip coil until the inside diameter of the at least one strip coil is enlarged.
  • the method according to the invention includes positioning at least one additional strip coil between the untwisting unit and the at least one enlarged strip coil, rotating the untwisting unit and the at least one additional strip coil relative to one another, pressing the untwisting unit against the inside of the at least one additional strip coil to the inner diameter of the at least one further strip coil is increased.
  • the method according to the invention also includes pressing the at least one further strip coil against the inside of the enlarged at least one strip coil.
  • the formed multi-part strip coil is compressed.
  • the at least one strip coil is pressed in the radial direction against a delimiting structure.
  • the limiting structure can consequently brake the outermost strip coil at this point against rotation or keep it stationary and thus facilitate turning. Furthermore, the delimitation structure allows a better pressing compaction of the individual strip coils in the multi-part strip coil by the untwisting unit.
  • the untwisting unit rotates, in particular about a vertical axis of rotation.
  • the relative rotation can be brought about solely by the untwisting unit, while the at least one coil of tape need not be rotated independently.
  • a vertical axis of rotation enables a strip coil to be positioned in relation to the unwinding unit with its coil eye also pointing vertically upwards.
  • the strip coil can be untwisted very evenly and easily by the untwisting unit in a radial, horizontal direction.
  • the untwisting unit is rotated about an axis of rotation in variable radii and, as the radius increases, is pressed against the inside of the at least one strip coil.
  • a force and/or movement introduced in the untwisting unit is converted into a radial compressive force and/or movement against an inner side of the strip coil.
  • the force and/or movement introduced can also undergo a desired change in amount, for example an increase or decrease, during the conversion.
  • the introduced force and/or movement can be converted into a radial force and/or movement by a combination of linear actuator and scissor mechanism.
  • This combination allows a particularly compact, for example columnar, and reliable design of the untwisting unit.
  • At least one radially extendable extension arm of the untwisting unit is rotated and, in the process, presses against the inside of the at least one strip coil with an increasing radius.
  • Such an embodiment reliably enables controllable pressing and rotating against the inside of the at least one strip coil.
  • the cantilever also enables a compressive force and a rotational force to be applied simultaneously by the cantilever against an inside of the at least one strip coil.
  • a plurality of radially extendable extension arms of the untwisting unit rotate and press against an inside of the at least one strip coil with increasing radii, in particular with the same radii simultaneously increasing.
  • the inside of the at least one strip coil can be radially pressed at several points at the same time, which allows the at least one strip coil to be untwisted more evenly. Simultaneously increasing the same radii enables simultaneous and equally strong pressing at several points on the inside of the at least one strip coil, and thereby easier and more uniform untwisting as well as uniform radial compression of the formed multi-part strip coil.
  • all cantilevers rotate at the same speed.
  • the inside of the at least one strip coil experiences the same rotational force from all the arms.
  • the cantilevers rotate in the circumferential direction at equal distances from one another about the axis of rotation.
  • the multi-part strip coil is formed on a coil transport means, in particular formed in a coil transport container.
  • the multi-part strip coil is already on a coil transport means for subsequent further processing.
  • the optional forming in a coil transport container protects the worker from the individual strip coils.

  • the multi-part strip coil can be formed lying on the coil transport means and can be easily transported to subsequent work steps.
