Abstract
A process and device for treating sheet objects, especially fragile sheet objects, by rotation through a liquid bath. The objects are disposed in radial slots in a rotating disk, retained therein by a flexible element moving synchronously with the disk, and by a retaining element mounted adjacent the disk and spaced therefrom along its axis of rotation.
Claims28
A process for treatment of sheet objects, comprising the steps of:
- supplying the objects to a container containing a treatment fluid by a conveyor belt;
- rotating the objects through the fluid by means of at least one disk rotated about a rotational axis with alignment of the objects about the rotational axis, thereby treating the objects;
- retaining the objects during the treatment in slots of the at least one disk that are radial relative to the rotational axis, by a retaining element adjacent said rotation device and spaced therefrom along said axis of rotation, and further retaining the objects in a receptacle during passage through the fluid by a flexible securing element that is moved synchronously with the rotation device adjacent the rotation device at its periphery, the flexible securing element preventing relative movement of objects retained in the slots and the securing element;
- moving the treated objects translationally after the treatment;
- and
- supplying the treated objects to at least one washing and/or drying step.
3 more elements
Device for treatment of sheet objects, comprising:
- a container constructed and arranged for filling with fluid bath for treatment of the objects;
- a feed device arranged upstream of the bath;
- a conveying device passing the objects through the bath, the conveying device comprising at least one disk with radial slots therein constructed and arranged to receive the objects, and means for rotating the at least one disk about an axis of rotation;
- a securing element disposed within the container and extending in a peripheral area of the receptacles for retaining the objects in the slots, the securing element comprising a flexible element moving synchronously with the at least one disk, and preventing relative movement of objects retained in the slots and the securing element;
- a retaining element adjacent the at least one disk and spaced therefrom along the axis of rotation;
- a removal device arranged downstream of the container, and
- washing and/or drying means arranged downstream of the bath with associated transport means for conveying the sheet objects thereto.
