Definitions

  • the invention relates to a roll cutting machine of the backup roll type with an automatic feeding of winding tubes.
  • a feed bar must be provided for each of the two winding stations arranged on the side of the support roller (s). which extend across the entire machine width, which can be eight to ten meters, and are supported 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 each other, the two channels lie so close to each other 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 feed bar end onto the trough of one or the other feed bar and pushed in their entirety along the two troughs into the takeover positions corresponding to the positions of the winding device by means of a slide.
  • the distribution of the winding cores on the two channels belonging to each of the winding stations is thus already done when the channels 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 tubes, 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 that receives them from a first to a second stable position, where they are prevented from rolling out of the gutter by a stop that can be pivoted in turn.
  • the stoppers are pivotally attached to the feed beam under spring force, so that the stopper plate located in the region of the support arms of the winding devices can avoid the support arms.
  • This known feed device has three disadvantages in particular: First, there is the risk that when the winding tubes roll from one to the other stable position, the momentum (momentum) of the rolling winding tubes becomes so great that the rounded stopper plates cannot stop this rolling movement. This risk exists especially in the case of winding cores with a relatively large diameter and / or a relatively large weight. Secondly, the adjustment of the winding sleeves with respect 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 process. After all, it is difficult to move the winding cores exactly on their different positions in their transfer positions.
  • 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 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 rollers both from below and from above.
  • the straight-line 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 have to 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 inclination angles of the linear transport movement can be small in terms of the preferred, pure vertical movement; Both measures (lifting and inclining the clothes) 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 elements, ie. H. from such transport devices which carry out a straight-line movement sequence, as is the case with the, to that extent preferred, piston / cylinder arrangements, spindle drives, linear motors and similar linear transport devices.
  • the transport movement takes place only in a straight line, i. 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.
  • a certain transport device is preferably assigned to each of the winding devices of a slitter-winder. It is basically 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 and is arranged to be movable together with it; then a transport device in each case consists of two lifting or lowering elements arranged spatially separated from one another.
  • each winding station i. 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 elements for the winding cores provided for the machine side in question on a traverse moved jointly by the two lifting / lowering elements without the. Leaving basic ideas of the invention.
  • the axes of all the winding tubes lie on a common straight line or, if the winding tubes have different diameters, the winding tube axes lie 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 tubes are pushed into the "gutter" from one end of the machine, there is still no division into the two sides of the machine, ie. H. on the two winding stations, as required by DE 38 00 702 A1.
  • the takeover of the winding tubes from the "groove” by the receiving members of the lifting / lowering members is now preferably carried out (claim 4) in that the winding tube receiving elements of the individual transport devices are arranged in their winding tube receiving position so that they "catch” the "dropped” winding tubes.
  • the “dropping" of the winding tubes on the "groove” is already known from DE 37 37 503 A1 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 become laterally spaced from one another.
  • the "catching" of these winding cores by the receiving members 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 make the division of the winding tubes 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 approximately into the positions of the winding tubes, in which the winding tubes are located in the "groove", in order to directly there the respective winding tube, for. 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 (based on 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, if appropriate, 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.
  • 10 as a whole denotes an unwinding station for at least one wide roll 11 of a web 12 of paper or the like.
  • the unwound, but still undivided web 12 is a cutting station designated as a whole by 20, which u. a. a plurality of rollers 21, 22, (rollers) ... has at least one slitter 23 and other known organs supplied.
  • the partial webs 24,... Created in the cutting station 20 by longitudinal division of the web 12 are fed to a support roller 30 which extends over the entire machine width and which, if appropriate, can have a vacuum suction facility for holding partial web ends.
  • a winding station 40, 50 each consisting of at least one, preferably a plurality of winding devices 41, 51.
  • Each winding device 41 and 51 consists (in the core) of a pair of support arms 42 and 52, which are provided with tensioning devices 43 and 53 at their free ends.
  • the tensioning devices 43 and 53 can engage in tubular winding sleeves 44 and 54 from the ends of the winding sleeves, can be clamped in a rotationally fixed manner with the winding sleeves and can be driven in the direction of rotation (center winder) - see also FIGS. 7 to 10.

  • the pivoting path of the winding axis is shown as a dash-dotted line 46 or 56.
  • the pivoting process of the support arms 42 and 52 takes place by means of piston / cylinder devices 47 and 57, which in turn are pivotally mounted about axes 48 and 58, respectively.

  • the support roller 30 is supported by a frame formed from sections 31 shown in detail and a crossbeam not shown. -
  • the components described above are known per se in reel cutting machines and therefore do not require any further detailed explanation.
  • All of the winding sleeves 44 and 54 forming a set, which are required for a winding operation, are fed to the slitter rewinder via a feed device 60 which is known with regard to its general function, and to the individual winding devices 41 and 51 there.

  • the transport devices 70 are lifting / lowering members with a - in the exemplary embodiment, double-armed receiving member 71, which is attached to the upper end of each lifting / lowering member and a positionally accurate receiving and storage during transport into the clamping position along the dash-and-dot line 72 allows.

Characterized in that the curved lines of movement of the winding axes of the support arms 42, 52 are cut in the clamping position from the straight lines of movement of the winding tube axes, the transport devices only have to stop at predetermined points so that tubes of different thicknesses can be moved precisely centered into the clamping position.

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.
