Abstract

Described herein is a method for breaking out a pattern (1) embedded in loose particulate matter (2), whereby the pattern (1) is arranged on a platform (4) movable at least vertically. At least during breakout, the movable platform (4) is enclosed in a container (3) that is open at least in the upward direction as viewed from the platform (4) towards the pattern (1). The platform (4) is displaced at the desired settable speed upwards in the direction of the pattern (1) and the loose particulate matter (2) is removed simultaneously.

Claims

1. A method for breaking out a pattern embedded in loose particulate matter, whereby the pattern is arranged on a platform movable at least vertically, which at least during breakout is enclosed in a container that is open at least in the upward direction as viewed from the platform towards the pattern,

characterised in that

the platform (4) is displaced at the desired settable speed upwards in the direction of the pattern (1) and the loose particulate matter (2) is removed simultaneously.

2. The device according to claim 1,

characterised in that

the displacement of the platform (4) occurs stepwise.

3. The device according to claims 1 or 2,

characterised in that

the loose particulate matter (2) is removed through vacuuming.

4. The device according to one of the foregoing claims,

characterised in that

the loose particulate matter (2) is removed through brushing.

5. The device according to one of the foregoing claims,

characterised in that

the loose particulate matter (2) is removed only from above the pattern (1).

6. A device for breaking out a pattern embedded in loose particulate matter, whereby the pattern is arranged on a platform movable at least vertically, which at least during breakout is enclosed in a container that is open at least in the upward direction as viewed from the platform towards the pattern, especially for application in a method according to one of the foregoing claims,

characterised in that

the container (3) has a grating (6) arranged at least partially around it.

7. The device according to claim 6,

characterised in that

under the grating (6) are drawers (7) for collecting the loose particulate matter (2).

8. The device according to claims 6 or 7,

characterised in that

the platform (4) is transported on at least one roller conveyor (8).

9. The device according to claim 8,

characterised in that

at least one step deck (5) is arranged across the roller conveyor (8).

10. The device according to claims 6 to 9,

characterised in that

at least one operating console (11) is provided to enable the platform (4) to be displaced at the desired settable speed.

11. The device according to claims 6 to 10,

characterised in that

an operating console (11) for displacing the platform (4) is provided on at least two sides of the device.
