A method and apparatus for cyclically shielding a work chamber opening (25) when loading and unloading workpieces using a conveyor device (10) that passes through the work chamber opening. A first shielding element (21) is placed at a workpiece loading station (11.1), and a second shielding element
A method and apparatus for cyclically shielding a work chamber opening (25) when loading and unloading workpieces using a conveyor device (10) that passes through the work chamber opening. A first shielding element (21) is placed at a workpiece loading station (11.1), and a second shielding element (22) is placed behind a second workpiece placement location (11.2), as viewed in the conveying direction. When the first workpiece is loaded into the work chamber (20), the first shielding element (21) is placed at or in the work chamber opening (25) by advancing the conveyor device (10). The first shielding element (21) is then removed from the work chamber opening (25) and placed behind the second shielding element (22). These steps are repeated with subsequent workpiece placement locations (11.2, 11.3, . . . ) of the conveyor device (10) and with respective cross-over changes of the shielding elements (21, 22).

1. A method for cyclically shielding an inlet opening in a work chamber when loading workpieces into said chamber using a conveyor device having a succession of workpiece placement locations that cyclically move through a workpiece loading station located outside of said chamber adjacent said openin
1. A method for cyclically shielding an inlet opening in a work chamber when loading workpieces into said chamber using a conveyor device having a succession of workpiece placement locations that cyclically move through a workpiece loading station located outside of said chamber adjacent said opening and thereafter pass through the work chamber, said method comprising the following steps: (a) placing a first workpiece on a workpiece placement location of the conveyor device at the workpiece loading station;(b) placing a first shielding element on the conveyor device in front of the first workpiece placed thereon, as viewed in the conveying direction;(c) placing a second shielding element on the conveyor device behind the first workpiece placed thereon, as viewed in the conveying direction;(d) loading the first workpiece that was placed on the conveyor into the work chamber and placing the second shielding element at the work chamber opening by advancing the conveyor device;(e) placing a second workpiece on a workpiece placement location of the conveyor device at the workpiece loading station;(f) removing the first shielding element from the conveyor device and placing the same on the conveyor device behind the second workpiece that was placed thereon, as viewed in the conveying direction, by using a transporting device; and(g) repeating steps (d) (e) and (f) with successive workpiece placements on the conveyor device at the workpiece loading station and with respective cross-over changes of the shielding elements. 2. A method as in claim 1, wherein the shielding elements are positioned between the workpiece placement locations and the workpieces placed there. 3. A method as in claim 1, wherein container-shaped shielding elements are used that are positioned on the workpiece placement locations and are put over the workpieces placed there. 4. A method as in claim 1, wherein the shielding elements are set onto the conveyor device. 5. A method as in claim 1, wherein the shielding elements are inserted into the upper side of the conveyor device. 6. A method as in claim 1, wherein a continuous conveyor device is used that leads into a first work chamber through a first work chamber opening and leads out of it at a second work chamber opening. 7. A method as in claim 6, wherein a rotating satellite table is used as the conveyor device, where the workpiece placement locations are arranged in a circular, ring-shaped area. 8. A method for cyclically shielding an outlet opening in a work chamber when unloading workpieces from said chamber using a conveyor device having a succession of workpiece placement locations that cyclically pass through the chamber and thereafter move past a workpiece unloading station located outside of said adjacent said opening, said method comprising the following steps: (a) placing a first shielding element on the conveyor device at the work chamber opening;(b) one moving a workpiece that is positioned on a first workpiece placement location of the conveyor device through the work chamber opening, and advancing the first shielding element, by advancing the conveyor device;(c) placing a second shielding element on the conveyor device at the work chamber opening behind the first shielding element, as viewed in the conveying direction, and behind the first workpiece placement location using a transporting device;(d) removing the workpiece from the conveyor device at the workpiece unloading station; andrepeating steps (b), (c) and (d) with regard to the additional, successive workpiece placement locations and with cross-over changes of the shielding elements. 9. A method as in claim 8, wherein the shielding elements are positioned between the workpiece placement locations and the workpieces placed there. 10. A method as in claim 8, wherein container-shaped shielding elements are used that are positioned on the workpiece placement locations and are put over the workpieces placed there. 11. A method as in claim 8, wherein the shielding elements are set onto the conveyor device. 12. A method as in claim 8, wherein the shielding elements are inserted into the upper side of the conveyor device. 13. A method as in claim 8, wherein a continuous conveyor device is used that leads into a first work chamber through a first work chamber opening and leads out of it at a second work chamber opening. 14. A method as in claim 13, wherein a rotating satellite table is used as the conveyor device, where the workpiece placement locations are arranged in a circular, ring-shaped area. 15. A work chamber for blasting treatment of workpieces comprising: at least one blasting agent source disposed in the interior of the work chamber for blasting workpieces with abrasive or surface-compacting particles;an inlet gate having an inlet opening and a first and a second shielding device, each shielding device having at least one deflector surface;an outlet gate having an on open in and a first and a second shielding device, each shielding device having at least one deflector surface;a convey device extending through the inlet and outlet gates of the work chamber and having multiple workpiece placement locations, where at least one receptacle is provided for each of the shielding elements; anda transporting device arranged in each of said inlet gate and in said outlet gate, each transporting device having a lifting device for raising and lowering a gripping device configured to receive the shielding elements and a transfer device for moving the lifting device along the conveyor device;wherein each transporting device is operative to place the shielding devices in the respective inlet and outlet opening, such that the direct trajectory of the particles from the blasting agent source is intercepted by the deflector surfaces. 16. A work chamber as in claim 15, wherein the shielding elements have at least one pin at their bottom side that can be inserted into a receptacle in the upper side of the conveyor device. 17. A work chamber as in claim 15, wherein the shielding elements each have at their upper side at least one catch element, on which at least one coupling element is arranged. 18. A work chamber as in claim 17, wherein the catch element is designed in the shape of a bar and extends through a stationary sliding guide. 19. A work chamber as in claim 18, wherein the sliding guide has an H-shaped design with two cross-slots oriented perpendicular to the conveying direction into which the shielding elements can be moved and with a longitudinal slot that leads into the cross-slots and in which the catch element can travel. 20. A work chamber as in claim 17, wherein the coupling element has a prismatic design at its upper side and wherein the gripping device has a catch element that is compatible thereto. 21. A work chamber as in claim 17, wherein the coupling element is rounded at its bottom side and wherein the gripping device has concave claws.
