Definitions
- the present invention relates to a device for removing a Surface layer, in particular primer of coated sheets and for marking the sheets with a removal unit and a Marking tool.
- a portal machine for example by means of a portal machine can be moved over the sheet in the X-Y direction, can One of the primer line-shaped with a width of 50 - 60 mm away and at the same time subsequently in the area of the free-radiated Line with the marking tool a mark on the Sheet metal to be applied. In a subsequent operation can then in the free-radiated, so clean sheet metal area another Component applied to the mark and then welded to the sheet become.
- Fig. 1 shows, while the Abtragdüse (blasting head 10) on the carriage 11 a Portal machine 12 attached as well as right and left of the blasting head 10th in each case a marking tool 13, 14 fixedly arranged.
- the unit, consisting from the blasting head 10 and the marking tools 13, 14 can thus only work in double arrow 15, 16, while moving of the jet head 10 in the direction of arrow 15, the marking tool 13 is turned off is and the marking tool 14 is working.
- the marking tool 14 is turned off and marking tool 13 operates, i. the jet head is running always ahead of the marking tool.
- the object of the present invention is to provide a device which does not have these disadvantages.
- the invention proposes that the marking tool around the Abtragdüse (jet nozzle) rotatable is. It will be through this rotatable arrangement easiest possible, on the one hand with only one marking tool both in To mark arrow 15 as well as in the direction of arrow 16. It's just a turning of the marking tool by 180 ° around the jet nozzle necessary.
- the NachFEen can be simplest be effected by a motor, which has corresponding signals a machine control is controlled.
- the beam-marking unit 26 has, according to FIG. 3, a removal / jet nozzle 28 on, the lines not shown with a sand blasting unit 29 is connected, which is shown schematically in Fig. 2 is and is preferably moved together with the carriage 20.
- the nozzle 28 is fixedly provided in a holder 30, the Querlauf- 7 carriage 11 is attached.
- the holder 30 is of a rotatable sleeve 31, 31b surrounded, in which a Pulvermarkierwerkmaschine 32 is attached and whose rear part 31b as gas distribution for the powder marking tool 32 serves.
- the sleeve 31 is about ball bearings 42, 43 and tapered roller bearings 44 rotatably mounted relative to the holder and the jet nozzle.
- the Sleeve 31 is connected to a holder 33 mounted on the engine 33 via transmission 34 in operative connection.
- the motor 33 is not on signals from the controlled machine control of the gantry machine, wherein the machine control and motors for the carriage 19, 20 and the cross carriage 11 according to the desired line course controls.
- On the holder 30 is also a gas supply 35 for the Pulvermarkierwerkmaschine provided in the oxygen inlet with 36 and the fuel gas inlet are designated 37.
- the powder feed is not shown in detail.
- the marking tool 32 rotated in the direction of arrow 38 or 39, so that any Straight lines as well as arbitrary curves are blasted and simultaneously can be marked.
- the marking tool 32 falls Central axis of the sand blasting nozzle 28 with the rotation axis 40 together and the marking tool 32 is running with an offset 41 (see Fig. 3) and the sandblasting nozzle.
- This embodiment is with large sand blasting nozzles especially advantageous.
- For smaller jet nozzles is also a reverse arrangement of jet nozzle around the marking tool conceivable. In this case, then the jet nozzle of the Marking tool turned.
