Patent ID: 8607729

Claim:
A line for dip coating objects comprising: at least one dip tank, which is capable of being filled to a certain level with coating fluid; a conveyor system, which conveys the objects to be coated towards the at least one dip tank, into the at least one dip tank, out of the at least one dip tank and away from the at least one dip tank, and which has a guide device and at least one transport carriage which is capable of being moved along the guide device and which in turn comprises: a drive motor for a movement along the guide device; a holding frame to which at least one object is capable of being fixed; an immersion device which has at least one rotational or pivot axis and to which the holding frame is fixed; a control device in which a set immersion curve of the at least one object fixed to the holding frame is stored and which controls a movement of the at least one object fixed to the holding frame; a collision prevention system which comprises: a position transducer for measuring an absolute value for each possible degree of freedom of movement of the at least one object-fixed to the holding frame; a memory in which a course of a first boundary surface or boundary line is stored, which reproduces a course of hard structures along a movement path of the at least one object; a memory in which a course of a second boundary surface or boundary line is stored, which runs at a distance from the first boundary surface or boundary line, wherein an anti-collision area is formed between the first boundary surface or boundary line and the second boundary surface or boundary line; a memory in which a course of a contour is stored, which represents a course of a contour of the at least one object fixed to the holding frame; and, wherein the control device, from signals delivered to the control device by the position transducer and the stored data relating to the course of the second boundary surface or boundary line and relating to the contour representing the at least one object fixed to the holding frame, calculates a position of the boundary line continuously or at particular time intervals and whether the contour penetrates the anti-collision area or not and, in the first case, stops a further movement of the object.
