At least those collets of the conveyor device that are in the area of the rear workpiece edge are in the lowered working position and the collets are open.
  • Step b. comprises accelerating the movement of the conveyor device in the conveying direction. The acceleration preferably begins when it is determined that the collets are in the area or near the rear workpiece edge. Due to the accelerated movement of the conveyor device on the one hand and the mass inertia of the workpiece lying on the feed table on the other hand, the rear workpiece edge is moved in the direction of a contact surface of a respective collet. At least two collets can each have a sensor device from whose signals a position of the rear workpiece edge can be determined. relative to the contact surface of the respective collet can be determined.
  • the feed table can have a braking device which, when the workpiece is moved in the conveying direction, exerts a force on the workpiece that acts in the opposite direction to the conveying direction.

  • Step c. comprises clamping the area adjacent to the rear edge of the workpiece by the at least two collets when a distance of the rear edge of the workpiece relative to the respective contact surfaces of at least two collets falls below at least a first limit value. In this way, it is ensured that the edge of the workpiece is only clamped by the collets when there is a sufficient overlap defined by the first limit value between the clamping jaws of the respective collet and the rear edge of the workpiece or when such an overlap can be assumed.
  • the distance of the rear edge of the workpiece from the respective contact surfaces is measured by a corresponding sensor device of the at least two collets.
  • the sensor device comprises a distance sensor which is arranged in such a way that the rear edge of the workpiece is detected independently of a plate thickness and a plate format.
  • the sensor device can comprise an ultrasonic sensor.
  • other measuring methods can also be used, for example tactile sensors, optical sensors, capacitive sensors or proximity sensors. With all of these sensor devices, it can be very easily detected how well or whether the workpiece with a rear workpiece edge is already resting on the contact surface of the respective collet or is located in the area of this contact surface.
  • the distance of the rear edge of the workpiece relative to the contact surface of the at least two collets falls below a second limit value.
  • the second limit value is therefore selected in such a way that when it is reached and/or fallen below, it can be assumed that the rear edge of the workpiece is at the contact surface the respective collet.
  • the workpiece is thus aligned with the rear edge of the workpiece on the contact surfaces of at least two collets, so that alignment on an alignment device in the area of the machine table is not necessary. In this way, the loading time is shortened even further.
  • the second limit value is smaller than the first limit value, preferably that the second limit value is approximately zero.
  • This further development comprises both that two different limit values are present, wherein the first limit value ensures that the workpiece is sufficiently clamped by the corresponding collet, whereas the second limit value ensures that the rear edge of the workpiece is aligned with the contact surfaces of the at least two collets.
  • the collets can still be closed. This means that the alignment process cannot be skipped, but the workpiece can be pushed in at high speed, i.e. moved towards the machine table. After braking the Before the conveyor device or the workpiece reaches an alignment device arranged in the area of the machine table, the collets are then opened again so that the material can then be aligned positively on the alignment device as before.
  • this further development also includes the fact that the two limit values are not different, but that they are essentially one and the same limit value, which in this case is preferably close to zero. With such a limit value, both sufficient clamping of the area adjacent to the rear edge of the workpiece by the collets is ensured, as well as alignment of the rear edge of the workpiece on the contact surfaces of the collets.
  • the second limit value is automatically determined depending on a raw plate tolerance and/or a planned dividing plan for the workpiece.
  • this limit value can also be adjusted dynamically from the empirical values for the raw plate tolerance and the cuts planned in the dividing plan. For example, a workpiece whose cutting plan contains very large cuts does not have to be aligned as precisely as a workpiece whose cutting pattern contains very small cuts.

  • at least one sensor device can be installed in the machine table or in the vicinity of the machine table, with which the front edge, i.e. a front workpiece edge as seen in the conveying direction, of the workpiece can be detected during movement through the conveyor device towards the machine table and thus, as an alternative to form-fitting alignment, an actual dimension of the workpiece as seen in the conveying direction can be at least roughly measured.
  • This at least one sensor device can, for example, be used as a distance sensor or as a proximity sensor with tactile, optical, capacitive or ultrasonic detection.
  • the sensor device can comprise a 2D laser scanner which is arranged parallel to a plane of the feed table and which can be used to detect a position and at least one dimension of the workpiece.
