  • the processing device according to the invention has a suction region of a suction device with an adjustable contour.
  • a suction opening with a variable, so adjustable width
  • it is particularly advantageous possible to change the geometry of the suction opening thus it is not constantly necessary to use the entire width z.
  • B. a wide belt sander, a brushing device or other processing devices, but it can be aspirated as needed in only one desired area. In this way, it is particularly advantageous possible to save aspirated air mass.
  • This extracted air mass must be produced under high energy use.
  • the device according to the invention allows energy-optimized and needs-based suck. It should be noted that in heated or cooled rooms, the extracted air volume must be supplied from the outside again and this is also to heat or cool again. Further reduces the noise level caused by the processing unit, since less air mass is sucked.
  • the processing device has a workpiece detection device, wherein the suction device communicates with the workpiece detection device.
  • the suction device communicates with the workpiece detection device.
  • the workpiece detection device is designed to start a suction operation of the suction device as soon as a workpiece is in a processing region and / or to end the suction operation of the suction device as soon as no workpiece is in the processing region. This makes it particularly advantageous possible to let the suction only take place when it is really needed. In this way, it is particularly advantageous possible to save energy.
  • the workpiece detection device is designed to detect the contour of the workpiece.
  • the workpiece detection device has sensing rollers and / or sensors, in particular optical sensors. This makes it particularly advantageous possible to convey the contours or the dimensions of the workpieces to the suction device. Alternatively, it is possible to obtain the data about the dimensions of the workpiece from, for example, dimensional data stored in a process flowchart.
  • the width of the suction region is adjustable as a function of the contour of the workpiece. By adjusting the width of the suction area to the contour of the workpiece, it is particularly advantageous possible to suck only in the area in which a workpiece is also located. In this way, it is particularly advantageous possible to save energy.
  • the width of the suction region is adjustable via a plurality of selectively switchable and disconnectable suction channels.
  • a suction channel segmented in its suction channel is formed with individually controllable segment locking elements, wherein the width of the suction region is variably adjustable.
  • a blow-off device in particular in the region of the suction device, is provided.
  • adhering particles in particular grinding dust
  • a blow-off device which has a plurality of selectively connectable or disconnectable blow-off nozzles.
  • By selective connection and disconnection of the blow-off nozzles it is possible to blow the blower, in coordination with the suction device, workpieces. It can thus be changed depending on the contour of the workpiece, both the width of the suction and the blowing area.
  • the change in the width of the blow-off is carried out by selectively switching on and off of the blow-off nozzles. This makes it particularly advantageous possible to save energy.
  • the invention further comprises a processing method for a processing apparatus according to any one of claims 1 to 11.
  • the workpiece is first detected by means of a workpiece detection device.
  • the suction device is switched on as soon as the workpiece is located approximately in a suction region of the suction device, wherein the width of the suction region corresponds approximately to the width of the workpiece detected by the workpiece detection device.
  • the suction device is switched off. This makes it particularly advantageous possible to suck only when a workpiece is in the detection range of the workpiece detection device and it is sucked only in the area in which a workpiece is located. This makes it particularly advantageous possible to save energy.
  • a suction channel segmented in its suction with individually controllable segment locking elements depending on the contour of the workpiece in the region of the workpiece opens the segment locking elements and thus able to suck in about this area. This makes it particularly advantageous possible to suck only in the area in which to be sucked and thus save energy.
  • a blower while the suction device is switched on, a blower is switched on.
  • the blower has several selectively switchable and turn-off nozzles.
  • the blower is formed approximately in the region of the suction device. In this way, it is possible to blow off adhering particles on the workpieces by means of the blower and then suck in by means of the suction device.
  • FIG. 1 and 2 show a processing device 12, in particular a wide-belt sanding machine, which has a processing device 12.
  • the processing device 12 has in the embodiment shown two suction devices 16 and a processing unit 30 with a grinding belt 13, wherein a suction device 16 is arranged in the conveying direction of the workpiece 15 in front of the grinding belt 13 and the other suction device 16 behind the grinding belt 13.
  • the suction devices 16 each have a suction opening 18, which extends over the entire suction area, in particular at least over the width of the conveying device 14 extending below the suction direction.
  • Suction ports 17 are formed on the suction device 16. By means of these suction connections 17, a negative pressure is generated in the interior of the suction device 16, as a result of which it is possible to suck off air having particles through the suction region 18.
  • a workpiece 15 is conveyed via the conveyor 14 (not shown) along the in Fig. 1 and 2 shown arrow moves in the direction of the processing device 12.
  • a workpiece detection device 20 recognizes the workpiece 15, it detects the contour, that is to say the geometric dimensions, of the workpiece and transmits these dimensions to the processing device 12.
  • the processing device 12 then adjusts the width of the suction region 18, depending on the dimensions of the workpiece 15. As soon as the workpiece detection device 20 detects that the workpiece 15 is in the suction region, the suction process is started. At the same time, the workpiece may be processed by the processing unit 30.
