Definitions

  • the invention relates to a method for cutting parts (cuts) from a material web, in particular a fabric web, according to the preamble of claim 1.
  • Such a procedure is common when cutting fabric panels.
  • a material web of limited length or a package of such material webs arranged one above the other is arranged on a cutting table, the material web dimensions being dimensioned within the surface area of the cutting surface of the cutting table.
  • fabric webs it is customary to arrange an air-impermeable film forming the cutting pattern over the fabric web or the package of the fabric webs, and to suck the overall arrangement by means of vacuum against the cutting surface of the cutting table in order to enable a precise cutting. A precise cut is required to reduce the amount of waste in order to optimally arrange the cuts close together.
  • the invention is further developed by the features of the subclaims. Furthermore, the method according to the invention is also optimized.
  • the method according to the invention ensures, on the one hand, that when the blanks which have already been cut and the waste which is inevitably formed are removed, the remaining material web which has not yet been cut remains unchanged and that the optimized cutting start point is reliably reached for the actual cutting start when this remaining material web is transported.
  • this can be achieved automatically in an automatically operating cutting device that is computer-controlled, using the computer.
  • this facilitates the operation of the cutting table, especially since it is expediently transported in such a way that a sealing lip corresponds to table-side sealing slides or similar sealing devices after the end of the transport.
  • the required vacuum output can be reduced.
  • the invention is explained on the basis of an exemplary embodiment in which strips of fabric arranged one above the other are cut together with an air-impermeable cover sheet in the manner customary in fabric cutting machines.
  • a single fabric web 10 the longitudinal dimension of which is significantly larger than that of the cutting surface 17 of a cutting table 16 which is conventional per se.
  • the cutting table 16 is arranged between a clearing station 18 and a buffer 19, the buffer 19 being, for example, a laying table , a feed table or the like.
  • the fabric 10 shown is finite in length, but it is also possible to pull a fabric directly from a bale (not shown).
  • This fabric web 10 is placed on the cutting surface 17 in such a way that it can be processed on the basis of a cutting pattern with a conventional cutting device, such as a butt knife machine or a cutting head or the like.
  • a separating cut 14 is provided in the exemplary embodiment, which is carried out over the entire width of the fabric web 10 in such a way that a first partial surface 11 is formed in which all the blanks 1 to 5 that have already been cut are located , and in such a way that a second partial surface 12 adjoins it, which extends over the feed-side end 21 of the cutting surface 17 extends to the buffer 19. If it can be optimized by the arrangement of the blanks, it is advantageous if there are no longer completely feasible blanks in the remaining surface 13 on the cutting surface 17.
  • a reference point 15 is first defined in the second partial area 12, preferably in the remaining area 13, this reference point 15 expediently corresponding to the starting point for the cutting of the second partial area 12.
  • the second partial surface 12 of the material web 10 is fixed in the exemplary embodiment, preferably by means of a retaining clamp 20, which acts on the second partial surface 12 outside the cutting surface 17 of the cutting table 16.
  • the rest of the surface 13 is expediently fixed in its position in relation to the transport device without activation of a transport device operating by suction, and the holding clamp 20 is then released and the second partial surface 12 is opened by means of the movement of the transport device the cutting surface 17 is moved.
  • reference point 15 is retrieved. On the one hand, this can be done manually, namely by tracking the cutting device to the defined reference point 15 on the second partial surface 12. This can also be done automatically by the cutting device looking for the marked reference point 15. This is particularly expedient if the reference point 15 coincides with the cutting start point for the second partial surface 12.
  • the above-mentioned data obtained for the reference point 15 can be updated depending on the transport movement, so that the information about the reference point 15 is available in every position of the second partial surface 12 on the cutting surface 17 for the cutting device and so that it can also be evaluated for the cutting process, which can shorten the search process considerably.
  • the method according to the invention can be used several times in succession if, after the first partial surface 11 has been cut, the remaining surface of the fabric web 10 is still too large to find space entirely within the cutting surface 17 of the cutting table 16.
  • the invention is therefore suitable not only for the formation of new cutting tables 16, but also for upgrading existing cutting tables 16, the cutting surfaces 17 of which have predetermined dimensions.
  • the invention is also applicable when proceeding without a cut 14. Then, after performing the cuts in a section corresponding to the first partial surface 11, the reference point 15 is determined and marked, which can then also be near the end of the first partial surface 11 on the feed side. This is followed by the joint transport of the machined partial area and the unmachined material web, fixing the position of this unmachined material web, locating the reference point 15, etc.
  • FIG 3 shows a side view of a raised cutting table 22 with a circumferential bristle band 24.
  • the bristle band 24 runs over transport rollers 27 and 28 mounted at the end, the drive device of which is not shown.
  • Sealing slides 29 and 30 are provided near these transport rollers 27, 28 in the region of the upper side of the cutting table 22.
  • a vacuum device not shown, is provided, which draws air in through the bristle band 24 in a manner known per se.
  • an air-permeable material web for example a multi-layer material web, which is covered by an air-impermeable film, lies on the section of the bristle band 24 between the sealing slides 29, 30, this is firmly sucked in and can be moved easily and without displacement of the individual layers with one another by means of a cutting device, not shown get cut.
  • Such cutting tables 22 are basically known with different designs. For example, reference is made to DE-PS 36 30 363.
  • the bristle band 24 consists of individual bristle elements that are even interchangeably arranged on a carrier.
  • sealing lips 26 are formed on the one hand so that they can be cut through by the cutting device and on the other hand designed so that they can be replaced after several such cuts.
  • the entire cutting table 22 has a length of approximately 12.28 m and the distance between the sealing slides 29.30 is approximately 10.36 m.
  • the distance between adjacent sealing lips 26 is selected so that a total of three such bristle band sections 25 correspond to the distance between the two sealing slides 29,30. That is, with such a cutting table 22, a cutting section corresponding to three bristle band sections 25 is available (cf. FIG. 4).
  • Fig. 4 shows in a first partial surface 11 blanks 1 ', 2', 3 ', 4' and 5 ', which are highlighted by cross hatching.
  • Individual cuts 6 'and 7' exceed the area of a sealing lip 25, it being assumed that this is the sealing lip 25 at the end of a first cutting section. Therefore, this should not be cut. Rather, a separating cut 14 'is to be provided on the side in the transport direction and also to be provided on the side of the sealing lip 25, which in this first cutting section is at the end of the entire first cutting section on the side in the transport direction.
  • the number of bristle band sections 25 assigned to a cutting section can be greater than the number shown, but it is expedient to choose this number not less than 3.
