Definitions

  • the invention relates to a method for cutting blanks from material webs which are moved over a cutting table and which are cut by means of cutting means, the blanks resulting in sectional position images which are shorter or longer than the cutting table.
  • the respective layer lengths must be a certain amount of safety (usually 3 to 5 cm) larger than the cut length to be cut in order to obtain a clean cut line at the end of each individual contour and also any tolerances when laying on the individual layers on the pallets or in the cutting tool setting.
  • a disadvantage of both methods is that the placement of the layers outside the cutting area results in high cycle times and the necessary safety additions require a high amount of waste for each layer, which not only increases the manufacturing costs, but also more or less depending on the type of material used causes high environmental pollution with the necessary waste disposal.
  • DE-AS 23 01 736 discloses a device for cutting a flat material, with which a more efficient way of working is possible, but the cutting method to be carried out with this device has the disadvantage that the material web always Equal distances are fed regardless of the cut to be cut. This results in long cycle times and a large machine length.
  • the invention is based on the object of specifying a method for cutting blanks from material webs with which low cycle times can be realized and which also makes it possible to dispense with the safety zone in the individual layers and to provide a device for carrying out the method.
  • FIG. 1 shows the cutting device, which essentially consists of the cutting system 2, the upstream laying station 9 and the downstream clearing station 10.
  • the laying station 9 contains the roll changer 1, a plurality of pallets P and the stationary clamping beam 5 and one or more carriages W1 ... Wn which are mounted so as to be longitudinally displaceable on the pallets P and on which the material rolls D1 ... Dn can be rotatably attached.
  • the clearing stations 10 serve to remove the cut-out patterns.
  • the portal 11 of the cutting system 2 is provided with a limit switch, not shown, which responds when a pallet P has entered the cutting area A and passes this switch.
  • material rolls D are loaded onto the trolleys W in accordance with the desired layer thickness of the material web 7.
  • the material rolls D are rotatably attached to the carriage W and these are applied to the roll changer 1 via the loading and unloading carriage 8 at each point X and material on the roll is passed under the tensioning bars 5, 6 (“threaded”).
  • the carriage W (in the drawing) is pushed to the left, so that it assumes the position X1 not previously occupied and the support point X becomes free again.
  • the entire sectional image SB is divided into individual segments S, the length of the individual segments S corresponding to the length of the cutting area A.
  • the individual patterns to be cut out are distributed within the overall sectional image SB taking into account the respective material width b in such a way that only a minimal waste remains. Possible methods for this are known from DE-OS 36 27 110. By using the method described below, it is irrelevant whether the contours to be cut extend beyond the segment boundaries SG or not, ie whether they are inside or still outside the cutting area A.
  • the cutting is started from the direction of the clearing station 10 to the laying station 9. It can be done with a double portal or as shown be worked with a mono cutting system.
  • the path-controlled cutting can be carried out by means of a conventional retraction control, wherein the individual contour data can be stored in the working memory of the control unit (how this can be done is shown in DE-OS 36 27 110 and DE-AS 23 01 736).
  • a contour cut K is made over the full width b of the material web 7, so that it is separated from the rolls.
  • this contour cut K does not take place in a straight line, but rather — as shown — encloses the patterns lying within the cutting area A, which extend beyond the respective limit of the currently cut segment S.
  • Patterns M1, M2, M3, which extend over two adjacent segments S, are therefore only partially cut out.
  • the NC-controlled cutting portal 11 moves back to the point Z of the partially cut-out pattern, which extends as far as possible into the cutting area A. This is necessary so that, as will be explained further below, the pallet P2 can be guided under the partially cut contours.
  • the stationary clamping bar 5 is lowered onto the material web 7 still connected to the rollers D, so that it is held on the laying station 9.
  • the subsequent pallet P2 is transported so far forward that it (almost) abuts the pallet P1 located in the cutting area A.
  • the fixation by means of the clamping bar 5 ensures that the material web 7 does not crease when it comes into contact with the pallet 2.
  • Both pallets P1 and P2 are moved to the right at the same speed (in the drawing) until the pallet P2 passes the limit switch (not shown) on the cutting portal 11 and the further transport is interrupted. Now it is ensured that all partially cut out patterns M1 or M2 or M3 have come to rest completely on the pallet P2.
  • the clamping bar 6 is lowered while the fixed clamping bar 5 is released, as a result of which the material web 7 is fixed on the pallet 2, and both pallets P1, P2 are transported further until the pallet P1 has completely reached the clearing station 10 and the pallet P2 in the cutting area A. is.
  • the clamping bar 6 is released and returned to its starting point.
  • the clamping bar 6 can be provided with its own drive, which runs synchronously with the feed device.
  • a suitable control program makes it possible to convert the coordinates (x / y) of the point Z into the current coordinates (xo / y) and the cutting portal 11 can move to the point at which the pattern has already been partially cut, and with the further cutting is continued again from the direction of the clearing station 10 to the laying station 9; at the end again a contour cut K over the complete Width b of the material web 7 is carried out and the process described so far begins again.
  • the cut-out patterns can be removed at the clearing station 10 during the cutting program.
