Definitions

  • the invention relates to a method for the automatic feeding of winding cores into a roll cutting machine of the support roller type according to the generic features of claim 1 and a roll cutting machine for performing this method.
  • a feed bar is provided for each of the two winding stations arranged on the side of the support roller (s). watch that extend over the entire width of the machine, which can be eight to ten meters, and are carried on the front of the machine by swivel arms. Both feed bars each have a trough for receiving the winding tubes.
  • the two feed bars When the two feed bars are swiveled towards each other and stand close to one another, the two channels lie so close to one another that there is only space for a single winding tube in each length section of the feed bar.
  • the winding sleeves which have already been cut to length, can be placed alternately from one end of the feed bar onto the trough of one or the other feed bar and pushed in their entirety along the two troughs into the transfer positions corresponding to the positions of the winding device by means of a slide.
  • the winding sleeves are thus divided into the two channels belonging to one of the winding stations as soon as they are pushed into the channels. In this case, a reliable division is difficult.
  • the feed bars In order to equip the individual winding devices with new winding sleeves, the feed bars must be pivoted on a circular arc in the direction of the pairs of support arms of the winding devices. During this swiveling process, the winding tubes roll in the gutter receiving them from a first to a second stable position, where they are prevented from rolling out of the gutter by a stop which in turn is pivotable.
  • the stoppers are pivotally attached to the feed bar under spring force, so that the stopper plate located in the area of the support arms of the winding devices can yield to the support arms.
  • This known feeding device has three disadvantages in particular: first, there is the risk that when the winding tubes roll from one to the other the stable position (momentum) of the rolling winding tubes becomes so great that the surface-rounded stopper plate does not stop this rolling movement can. This danger exists especially in the case of winding cores with a relatively large diameter and / or a relatively large weight.
  • the adjustment of the winding sleeves in relation to the clamping heads of the winding devices is particularly complex when the winding sleeve diameter is to be changed and / or even Sleeves of different diameters are to be wound during a single winding operation. After all, it is difficult to move the winding cores exactly on their different positions in their transfer positions.
  • This known winding tube feed device requires a relatively large number of movable parts.
  • the adjustment effort when changing the part web widths and / or the winding tube diameter is considerable.
  • the gripper arms when changing the width of the partial web, the gripper arms must independently, i. H. readjusted separately from the winding devices.
  • a box girder that extends across the entire width of the machine with side guide rails and slides that can be moved thereon must be provided.
  • the object of the invention is to create a method and a device of the type mentioned at the outset by which the automatic winding tube feed to the winding devices is simplified.
  • the invention u. a. accomplished that
  • the stopping point of the transport device in the clamping position can be adjusted simply and precisely, in particular programmably, so that sleeves with different diameters can be processed without problems, d. H. Both different sleeves on different winding devices and - fundamentally - different sleeves from winding operation to winding operation on the same winding device, this operation being able to run fully automatically.
  • the transport devices according to the invention can be used both in reel cutting machines with a single back-up roll and in reel cutting machines with two back-up rolls; Likewise, the partial webs can be fed to the support rolls both from below and from above.
  • the rectilinear movement according to the invention which is a lifting or lowering movement, does not have to be vertical, but can also be carried out obliquely, ie with a clear horizontal component; this is regularly necessary when the winding tubes are fed in a position above the one or both support rollers, that is to say that the partial webs are then usually fed to the support roller (s) from below. In these cases, the winding sleeves must be lowered from the transfer position into the clamping position by the transport devices.
  • the feed device for the winding sleeves is arranged below the, preferably single, or below the two support rollers, the winding sleeves are lifted from the transfer position into the clamping position by the transport devices and the angle of inclination can be adjusted the linear transport movement be kept small with respect to the preferred, pure vertical movement; Both measures (lifting and small angle of inclination) are advantageous for a calm and secure position of the winding tubes in the receiving elements on the transport devices.
  • the transport devices consist of lifting or lowering devices, ie. H. from such transport devices which carry out a straight-line movement sequence, as is the case with the preferred piston / cylinder arrangements, spindle drives, linear motors and similar straight-line working sports devices.
  • the transport movement takes place only in a straight line, ie. H. that the angular position of the transport devices with respect to the vertical direction remains constant during the entire lifting or lowering process. In principle, however, it is also possible to superimpose a certain pivoting movement of the transport device on the lifting or lowering movement.
  • Each of the winding devices of a slitter-winder is preferably assigned a specific transport device, it being particularly preferred that the winding device and the transport devices assigned to it are always movable together (claim 8). It is fundamentally possible to provide only a single lifting or lowering element for each transport device; it is preferred, however, that each side of each winding device, ie in particular each support arm, is assigned its own transport device, in particular is arranged to be movable together with it; then a transport device consists of two lifting or lowering devices arranged spatially separated from each other.
  • each winding station ie. H. to provide only a single pair of lifting or lowering elements on each side of the support roller (s), and to arrange all of the receiving organs for the winding cores provided for the relevant machine side on a traverse moved jointly by the two lifting / lowering elements without the basic idea to leave the invention.
  • the axes of all the winding cores lie on a common straight line or, if the winding cores have different diameters, the winding cores are located in a common vertical plane; this is already the case with the "gutter” known from DE 37 37 503 A1 and has the advantage that when the winding tube is pushed into the "gutter" from one end of the machine, there is still no subdivision on the two sides of the machine, ie. H. on the two winding stations, as required by DE 38 00 702 AI.
  • the take-over of the winding tubes from the "groove" by the receiving elements of the lifting / lowering elements is now preferably carried out ( Claim 4) in that the winding tube receptacles of the individual transport devices in their winding tube receiving position are arranged laterally of the channel in such a way that they "catch” the "dropped” winding tubes.
  • the “dropping" of the winding tubes on the "groove” is already known from DE 37 37 503 AI and includes that the winding tubes z. B at least one inclined plane is fed to each side of the machine, over which they roll due to their gravity, where they lose height and that the sleeves assigned to the two winding stations attain lateral spacing from one another.
  • the "catching" of these winding cores by the receiving elements according to the invention therefore means that the winding cores, which move freely after the division into the two machine sides, return to a defined position.
  • the lifting / lowering elements according to the invention to divide the winding cores over the two sides of the machine. This would be e.g. B. possible in that the receiving members of the lifting / lowering members are moved exactly or roughly into the positions of the winding sleeve, in which the winding sleeves are located in the "groove" in order to directly, there, the respective winding sleeve. B. by lifting the Take over the winding tube from the gutter.
  • a pivoting process of the lifting / lowering elements could pivot them into the angular position (relative to the vertical direction) that corresponds to the angular position for the transfer of the winding tubes into their clamping position; in particular, all lifting / lowering elements of one machine side could be pivoted together, while the lifting / lowering movement of each transport device and possibly also a method transverse to the direction of movement of the partial webs could be carried out separately, in particular programmed, for each lifting / lowering element.

Abstract

Dans un procédé et un dispositif pour l'insertion automatique de mandrins dans des machines à découper à roulettes du type à cylindre d'appui, une large bande (12) de papier ou similaire est déroulée d'un large rouleau (11) au niveau d'un poste de débobinage (10). Dans un poste de découpage (20), cette large bande (12) est divisée dans le sens la longueur en au moins deux bandes partielles (24) plus étroites. Dans deux postes de bobinage (40, 50) disposés chacun sur un côté du ou des cylindres d'appui (30) et constitués chacun d'au moins un enrouleur (41, 51), les bandes partielles (24) plus étroites sont enroulées avec utilisation de mandrins (44, 54) de telle manière que chaque bande partielle (24) voisine soit enroulée sur des postes de bobinage (40 ou 50) différents. Dans un dispositif d'insertion (60), les mandrins (44, 54) sont glissés successivement, en fonction des enrouleurs (41, 51) à équiper, dans une position de réception parallèle au cylindre d'appui (30) ou aux cylindres d'appui, répartis des deux côtés du ou des cylindres d'appui depuis leur position de réception et transportés dans une position de tension des enrouleurs (41, 51) pour y être tendus afin de recevoir ensuite la bande partielle correspondante. Les mandrins (44, 54) se trouvant dans leur position de réception et répartis des deux côtés du ou des cylindres d'appui sont repris par le dispositif de transport (70) associé à chaque enrouleur (41, 51) et soulevés ou abaissés en position de tension suivant un parcours essentiellement rectiligne. De cette manière, l'insertion automatique des mandrins est sensiblement améliorée, étant donné que le recours à des dispositifs mécaniques est relativement faible, en dépit d'une suppression d'importants travaux d'ajustage, d'une réduction des temps de préparation et d'une économie de personnel d'entretien.
