Definitions

  • the present invention relates to a method for cutting board, in particular gypsum board.
  • the invention also relates a device for cutting of board, in particular in connection with the said method.
  • Figure 1 is a sideways sketch showing the major components of a cutting installation in which the method and the device according to the invention may be realised.
  • Figure 2 is a sideways sketch on a larger scale of a section of the installation as shown in Figure l, comprising additional elements.
  • Figure 3 is an end-on sketch of the installation as shown in Figure 1.
  • Figure 4 is a sketch looking in the direction of the arrows IV- IV in Figure 1.
  • a raw length which is cut into large lengths of board subsequently to be cut into at least two or more standard finished lengths.
  • Shown in Figure 1 and Figure 2 is one part of such a raw length 1, which is here cut into a larger length of board 2, the said length of board 2 having been placed on a base 3 comprising a plurality of platens or belts 4 which are appropriately communicating with a driving means 5 at one end of the base 3.
  • the said length of board 2 which has been cut from a raw length may have been dried in advance to a consistency which will allow cutting to be done, and it shall furthermore be understood that the length of board 2 may be brought onto the base 3 either in the lengthwise or the sideways direction.
  • the length of board 2 of suitable dryness will then according to the present invention be multi-cut across by means of an initial set of pre-adjusted cutting means 6n set at selectable intervals to each other of Ll, L2
  • the said initial set of cutting means 6n is part of a device 7 comprising at least one additional set of pre-adjustable cutting means 8n, see Figure 4, which acts as a back-up set or will come into effect when other sets of finished lengths Ll ... Lm are to be cut.
  • the said device 7 which supports the first set of pre-adjusted cutting means 6n, and the additional set of pre-adjustable cutting means 8n may comprise a rotatable, elongated supporting means 9, e.g. designed as a hollow pipe, or such like, extending along the whole length of what is relevant to the larger lengths of board 2.
  • the pipe shaped supporting means 9 is provided with e.g. a hydraulically driven rotating means 10 which serves to rotate the actual device 7, e.g. 90°, so that either the initial set of cutting means 6n, or the additional set of cutting means 8n, may come to have an effect in the area of the said length of board 2.
  • the initial set of cutting means 6n is arranged on a first line along or in parallel with a common rotation axis 11 of the said device 7 , while at the same time the at least one additional set of cutting means 8n is arranged on a second line or in parallel with the said rotation axis 11 of the device, yet at a rotation angle distance ⁇ chosen here to be 45°, which, however, may naturally be varied within a wide range, e.g. between 30° and 60°.
  • the device 7 is arranged so that according to the invention it may comprise a plurality of sets of cutting means, preferably arranged each on its own line along and at intervals around a rotation axis.
  • the pipe shaped rotatable supporting means 9 is provided with sets of means I2n, lengthwise adjustable, supporting cutting blades, the said means being glidingly adjustable along the said supporting means in order that they may be adjusted lengthwise at the said intervals Ll, L2 ... Lm between the respective cutting blades 6n and 8n, corresponding to the standard lengths to be cut, e.g. 2.40 m or 2.50 ra, or other suitable "standard" lengths.
  • the cutting unit consisting of a pipe supported at either end, and surrounding the pipe there is an enforcement frame.
  • the pipe being supported can rotate.
  • the saws are mounted at an angle of 90°.
  • the saws being mounted on the pipe may be moved individually in the lengthwise direction of the pipe.
  • the move may be done manually or automatically.
  • the saw pipe is also used as a shared exhaust from the saws .
  • each of the cutting blades may be implemented as substantially circular main saw blades, and even more appropriately each saw blade may on each side be implemented with an additional blade which will, when the respective length of board is intersected by the main saw blade, chamfer off the cutting edges simultaneously with the said intersection.
  • the larger length of board 2 may be guided sideways towards the cutting table or the base 3, and the said sideways guiding may appropriately be done by means of transverse belts comprising at least two separate drives, preferably one master drive driving an initial number of drive belts, and a slave drive driving the remaining belts .
  • a slave drive as stated may appropriately communicate with means sensing an inclined position so that when the means sense an inclined position of the guiding edge of the board relative to references given, the slave drive will over or under synchronise its drive relative to the master drive, to correct the said inclined position, i.e. perform a 90° check, respectively a diagonal check for precise cutting with the correct result.
  • the cutting means communicate with adjoining collecting table (s) for cut boards of standard length, the collecting table (s) com ⁇ prising subdivided belt sections with individually rever ⁇ sible drives, for transporting the cut boards in either one or two directions.
  • the two directions may then suitably depend on sections given a suitable standard length for subsequent stacking of identical lengths.
  • Maintenance may be carried out on the saws not in use, a preventive maintenance which reduces the number of times operations are interrupted.

Abstract

Cette invention concerne un procédé et un dispositif qui permettent de découper des plaques, notamment des plaques de plâtre. Ce procédé offre une technique qui permet d'obtenir une plus grande finesse et une plus grand précision lors de la découpe de longueurs de plaques standards (L1 ... Lm), et de limiter ainsi les chutes lors de ladite découpe. A cette fin, le dispositif et le système décrits dans la présente invention font appel à un premier ensemble de systèmes de coupe (6a). Ces systèmes de coupe peuvent être réglés à des intervalles qui correspondent à un premier ensemble de longueurs finies (L1 ... Lm), ceci de manière à effectuer une découpe multiple de ces longueurs. Ce dispositif comprend également un ensemble complémentaire de systèmes de coupe à préréglage (8n), lesquels jouent le rôle d'ensembles de support ou entrent en action lorsque l'on doit effectuer une découpe multiple pour d'autres ensembles de longueurs finies.
