Definitions

  • the invention relates to a storage device for storing rod-shaped articles of the tobacco-processing industry, in particular filter rods, aligned cross-axially and parallel, comprising a magazine section with a feed area and a removal area, with the feed area being assigned at least one feed device which is designed to supply the storage device with the rod-shaped articles Feed articles transversely.
  • the invention further relates to a method for loading a corresponding memory device.
  • Such a storage device is known, for example, from EP 1 920 668 B1, the disclosure of which is incorporated herein by reference.
  • Such storage devices also known as filter magazines, are used in cigarette manufacture as temporary storage for the multiple-length filter rods that are manufactured, for example, in a filter rod unit and are cut to length from the endless filter rod in multiple use lengths.
  • the filter rods pass through one or several feeding devices in the filter magazine.
  • clocked-driven conveying drums with troughs are used for this purpose, into which the filter rods are initially injected longitudinally and parallel to the axis of rotation of the conveying drums, and then switched to cross-axial conveying by clocked rotation of the conveying drum.
  • the cross-axially conveyed filter rods then enter the magazine section of the storage device, where they are temporarily stored in a cross-axial parallel orientation.
  • Corresponding feeding devices are known, for example, from EP 1 397 966 A1, the disclosure of which is also referred to here in its entirety.
  • the rod-shaped articles are temporarily stored as a mass in a large number of horizontal layers one above the other. The removal takes place from below, the supply from the side, into the mass of rod-shaped articles.
  • the rod-shaped articles already present therein are partially displaced upwards, so that due to the dead weight of the stored rod-shaped articles, a pressure dependent on the filling level in the magazine section is exerted on the rod-shaped articles stored in the lower part of the magazine section article works. This pressure increases as more rod-shaped articles are fed into the magazine section, which can result in damage to the stored rod-shaped articles.
  • this problem is solved by introducing a relief unit for reducing a local pressure acting on the rod-shaped articles in the magazine section, which is designed as a transport element with an at least essentially vertically upward conveying path.
  • Rod-shaped articles are removed from the filled lower part of the magazine section and transported to the overlying parts of the storage stack, regardless of whether rod-shaped articles are removed from the store or not. This efficiently relieves the lower section and counteracts the build-up of high local pressure.
  • the stored rod-shaped articles are shaken and moved in a shaking manner, so that local pressure differences within the entire filling area over the entire fill level can be effectively dissipated, regardless of where the feed section is located.
  • the object of the present inventions is to make the filling of a storage device with rod-shaped articles from the tobacco processing industry even safer than was previously possible.
  • a loosening unit with at least one rotary element is arranged in the direction of the outlet of the at least one feed device, which has a rotary profile with a cross-section deviating from a circular shape, wherein an axis of rotation of the at least one rotary element is aligned parallel to the alignment of the rod-shaped articles in the storage device, wherein the loosening unit comprises a drive which transmits a rotary motion to the at least one rotary element.
  • the invention is based on the finding that with the known storage device, despite the relief unit, high local pressures can still occur in the feed area from the feed device or feed devices, which can lead to damage to the rod-shaped articles. This is due to the fact that the relief unit is usually located on the opposite side of the
  • Magazine section is arranged and thus the relieving effect in the opposite area, in which rod-shaped articles are supplied, has already greatly or completely subsided.
  • a rotary element with a rotary profile is arranged at the output of the at least one feed device, which is arranged with a rotation about an axis of rotation that is arranged parallel to the orientation of the temporarily stored rod-shaped articles. This reduces the local pressure in the feed area, so that the subsequent stick-shaped articles are fed into the magazine section with less pressure and thus less risk of being damaged.
  • the speed of rotation of the rotary profile can be adapted to the conditions of the storage device and the filling by simple tests and should be a maximum Do not exceed speed that would damage the rod-shaped items.
  • the rotary profile has at least two wings in cross section. Viewed in cross-section, the wings are arranged in such a way that they are in two-, three-, or four-fold symmetry with one another.
  • the turning profile is approximately triangular in cross-section, with the tips of such a “triangle”, which form the wings, being rounded off to protect the material and the sides of the triangle being drawn in towards the center of the triangle.
  • four wings can be arranged approximately in the shape of a cross.
  • the cross-section of the turning profile has an essentially oval or rounded, double-wedge-like shape. The rotary profile is thus essentially convex in cross-section, so that the rotary profile only displaces the rod-shaped article, but does not take it with it or transport it.
  • the loosening principle is based on the displacement of the rod-shaped articles.
  • the outermost points of the rotation profile describe a maximum circumference circle within which the rotation profile is located.
  • a circumferential circle around the turning profile is 3 to 15 times the diameter of the rod-shaped articles away from an outlet of the at least one feed device. This range of values ensures that the rotary profiles are not so far away from the at least one feed device that they no longer have a relieving effect, but are also not arranged so close to the outlet of the feed device that the newly fed rods in between are in the form of rods Articles are crushed by the rotating profiles.
  • the rotary profile has a diameter of its circumferential circle which is 2 to 20 times the diameter of the rod-shaped article.
  • each feed device in particular being assigned a rotary element, in particular of the same type.
  • the rotating profiles of the several rotating elements are preferably rotated through 90° to one another. This prevents the gaps between the turning profiles from becoming dangerously narrow and thus protects the rod-shaped articles.
  • the several rotary elements are connected to the drive via a chain, with the drive and/or the rotary elements being/are connected to the chain in particular via a slipping clutch or via slipping clutches or via one or more switchable clutches.
  • a single drive is sufficient for the multiple rotary elements.
  • the slipping clutch or slipping clutches stop the individual rotary elements in the event of a fault and ensure that they are not too high
  • switchable clutches makes it possible to switch the rotation of the rotating element or, in the case of several rotating elements, the rotation of individual rotating elements, on and off very quickly, which allows a faster reaction than switching off the drive itself.
  • the rotating elements can also be switched individually , so that it is possible to react individually to faults in the area of the outlets of individual feed devices without interrupting the operation of the other feed devices and rotary elements.
  • the fluffing unit is fastened to a sheet metal that is a wall of the magazine section, with the drive on the back of the wall outside of the magazine section and the at least a turning profile are arranged on the front of the wall section within the magazine section.
  • a loosening unit can also be retrofitted to existing storage devices.
  • the object on which the invention is based is also achieved by a method for filling an above-described storage device according to the invention, with rod-shaped articles from the tobacco processing industry being conveyed transversely axially by means of at least one supply device transversely axially through a supply area into a magazine section of the storage device.
