Definitions

  • the invention relates to a device for manually generating a spiral-shaped packaging material.
  • the packaging material is wound into a roll, it can be wound and / or withdrawn generically from either the outside or the inside of the roll. In the invention, the packaging material is unwound from the inside of a roll and / or peeled off.
  • a carrying device in the form of a movable dresser is described.
  • the dresser has a console on the side near the bottom, on which a first roll with vertical winding axis is placed.
  • the top of the dresser has two semi-circular ribs, in which a second roll with a horizontal winding axis is inserted.
  • Packaging material can be unwound by the user from the insides of both rolls by passing the stocking material from the first roll through the second and then draping the material from both rolls tubularly.
  • a cutting device Adjacent to the second roller, there is provided on the top of the dresser a cutting device, which is realized by a hand lever shears to divide a withdrawn packaging material tube into individual sections.
  • the user must first open the scissor lever with one hand, then pass the packaging material with the other hand through the opened scissors and then operate the scissors lever.
  • This is cumbersome and dangerous because the user has to reach with one hand through the opened shear area and peel off the packaging material, with each passing risk of injury, especially if the user is careless and releases or moves the scissors lever.
  • the chest of drawers takes up a lot of space and can only be positioned adjacent to the working surface of the user with a static output direction.
  • the well-known dresser is also disadvantageous in that for providing dense packaging material two rolls of paper be needed, which increases the cost of the device.
  • Annielder the need has been recognized to provide a device for manually generating a spiral-shaped packaging material, which should consume as little space in the workspace of the user.
  • the packaging material should be provided in close proximity to the user's work surface, and that the user be free to choose the position and orientation of the material output and also change it during use.
  • an apparatus for manually producing a packaging material comprises a receptacle and an adjoining axial holder with a dispensing opening and a tapered inner wall portion.
  • the packaging material can be, for example, paper, waste paper, soda kraft paper, soda-blended paper or roll corrugated cardboard.
  • the receptacle allows at least partially circumferentially encompassing a fiber material web roll, which defines an axial direction and forms an inner side from which the fiber material web is drawn off to form the packaging material.
  • the inside of the roll is formed by the innermost winding of the fibrous material web and includes the end of the fibrous material web which is withdrawn from the roll to form the packaging material.
  • the other, opposite end of the fiber material web is located on the outer periphery.
  • An Axialhalterung connects to the recording, where a front in the withdrawal direction axial end face of the fiber material web roll is held. When the fibrous material web roll is in the receptacle, it is supported radially on the receptacle and axially on the inside of the axial mount.
  • a discharge port for discharging the packaging material is formed in the axial direction.
  • the winding axis of the fibrous material web roll preferably extends through the dispensing opening.
  • the dispensing opening can also be configured slot-shaped, for example, and can not be arranged in alignment with the winding axis of the fibrous material web roll.
  • the windings of the fibrous material web roll are formed approximately circularly around the winding axis of the roll, which predetermines the orientation of the axial direction.
  • the axial holder has an inner wall section facing the front side of the fibrous material web roll, which tapers towards the dispensing opening.
  • the fiber material web roll resting on the inner wall section is preformed in the discharge direction, so that the innermost winding of the fiber material web roll is offset in the axial direction from the second and to every other, in particular the outermost, winding.
  • the fiber material web is guided to the discharge opening during removal so that the web drawn off to form the packaging material does not first undergo a change in direction directly at the delivery opening, but the change in direction has already been initiated beforehand so as to avoid unwanted tearing off of the fiber material web or of the packaging material ,
  • the inner wall section preferably tapers in a funnel shape in the axial direction towards the dispensing opening.
  • the funnel shape can taper constantly, increasingly, or decrease, that is to say preferably be conical or frustoconical, trumpet-shaped or bulbous.
  • the rejuvenation can for example also have a straight or crooked pyramidal shape.
  • the Axialhalterung may also have a plurality of tapered inner wall sections, which have different shape.
  • the inner wall section is rotationally symmetrical.
  • the entire axial support may be substantially rotationally symmetrical and / or have a substantially constant wall thickness.
  • a rotationally symmetrical, frusto-conical funnel shape is particularly easy to manufacture and thus particularly cost-effective.
  • a funnel-shaped inner wall portion of an axial support allows a well-defined guidance of the fiber material web roll or the withdrawn packaging material from the roll to the discharge opening, so that Premature tearing off of the fiber material web due to an unmediated strong change in direction of the web at the dispensing opening is avoided.
  • the opening angle of the inner wall portion is at most 150 °, in particular at most 100 ° and at least 30 °, in particular at least 70 °.
  • a small opening angle of the inner wall portion allows the paper web to be accurately guided toward the discharge opening and causes the packaging material to be spiral after peeling, whereby the packaging material is already compact and precompressed when it is dispensed so that it is particularly easy to provide a dense packaging material.
  • a large opening angle of the inner wall portion of, for example, 135 ° causes the packaging material to emerge from the dispensing opening in an increasingly elongated form, as the spiral turns move farther and farther apart, which is particularly suitable for providing packaging material that is rather flat.
  • a large opening angle of the inner wall portion has the advantage that when aligned means for manually producing a packaging material with output direction down, the mass of the fibrous material web roll is at least partially supported by the inner wall portion can be avoided by a large opening angle that the paper web of the roll alone their mass and gravity slips through the dispensing opening without a user deliberately pulling off packaging material.
  • the opening angle of the inner wall portion between 85 ° and 95 °, in particular about 90 ° is large.
  • an opening angle of the inner wall portion in the range between 85 ° and 95 °, in particular 90 ° is sufficiently large, in order to avoid even with oblique to vertical arrangement of the recording that the fiber material web roll unrolls independently and falls out of the discharge opening.
  • the receptacle on the axial support is in particular releasably attached.
  • recording and Axialhalterung be carried out in one piece, which simplifies the assembly, or be releasably connected to each other, so that the Axialhalterung can be replaced.

  • the rear mounting collar engages over the receptacle at least partially.
  • This allows a particularly simple and quick mountability of the axial support on the receptacle and allows the user to switch between different axial supports as required or to separate an axial support from the receptacle to simplify the assembly of the recording with a new fiber material web roll.
  • a mounting collar adjoins the inner wall section in the axial direction, so that further components, such as a blade for cutting off the packaging material, can be arranged in extension to the inner wall section.
  • a mounting collar is substantially cylindrical, thereby preventing the paper web from colliding with an edge of a mounting collar when unwinding from the circular roller.
  • the invention has a mounting collar on a backdrop that forms with a movable bolt, for example, the recording a bayonet and / or a snap connection.
  • a snap connection allows easy installation.
  • a bayonet lock is easy to assemble and provides, for example, in the axial direction increased restoring forces, which is particularly suitable for devices in which the packaging material down we deducted, since when the Axialhalterung is fixed with a bayonet lock on the recording, is easily avoided in that the axial support bearing the roller drops or slips off the receptacle.
  • the inner wall section may be fastened to the receptacle with a first fastening collar with a bayonet closure suggested above, and opposite to the mounting. take a blade around the dispensing opening of the axial holder to be bolted to a second mounting collar.

  • the inner circumference may, for example, have other shapes than a circular shape. If a cutting edge is arranged on the inner circumference of the dispensing opening, the device is particularly compact. If the cutting edge does not cover the entire inner circumference, the risk of injury to the user is particularly low and it is avoided that the fiber material web unintentionally comes into contact with the cutting edge during removal and accidentally tears off.
  • a ring knife allows a particularly rapid production of packaging material with the device, for example, because the user can move a paper web in any direction away from the dispensing opening to separate it from the roll.
  • the cutting edge has a plurality of teeth.
  • the teeth may for example be integrated into the axial holder, for example when the axial holder is a plastic injection-molded part.
  • the teeth may preferably extend at least partially radially inward and / or axially in the dispensing direction, in particular at an angle of approximately 45 ° to the axial direction.
  • the cutting edge has a mounting ring, which is realized in particular as a metal ring, which is externally mounted on the Axialhalterung.
  • a mounting ring allows the user to quickly and easily replace a worn cutting edge with a new one.
  • the mounting ring can be releasably mounted on the front of a mounting collar, preferably with at least one screw, in particular with three or four.
