Abstract

An arrangement for conveying an anode plate from one location to another, whereby said arrangement comprises gripping elements attached to a conveyor for gripping a plate-like piece. Elements are attached to the gripping element connection for the correction, at least partial, of any possible positional error of the anode to be transferred.

Claims

1. An arrangement for conveying an anode plate from one location to another, whereby said arrangement comprises gripping elements attached to a conveyor for gripping a plate-like piece, characterised in that the elements are attached to the connection of the gripping element for the correction, at least partial, of any possible positional error of the anode to be conveyed, wherein the elements for the correction of positional error comprise a gripping element gripper frame (11), to which gripper arms (12) are attached rotatably, and a fixing frame (15) or its like, where the gripping elements are fixed to the conveyor, and at least one support and/or spring element (18) attached between the fixing frame and the gripper frame and that a hinge element (16) is arranged between the gripper frame (11) and the fixing frame (15), which are movable with respect to each other in relation to said pivot.

2. An arrangement according to claim 1, characterised in that the arrangement comprises in addition at least one support and/or spring element (18).

3. An arrangement according to claims 1 or 2, characterised in that the gripper frame (11) is arranged together with the hinge element (16) using at least one support and/or spring element (18), in particular to correct at least partially, mainly with gravitation, any positional error with respect to the fixing frame (15) at least during the anode transfer stage.

4. An arrangement according to any of claims 1-3, characterised in that the grippers comprise grapple devices (13) on opposite edges of the anode, onto which are attached bearing surfaces (23) to carry the anode.

5. An arrangement according to any of claims 1-4, characterised in that the grippers also comprise at least one support surface (22) to support the anode on the opposite side of the anode compared with the bearing surfaces (23) of the grapple device.

6. An arrangement according to any of claims 1-5, characterised in that there are three support and/or spring elements (18).

7. An arrangement according to any of claims 1-6, characterised in that the support and/or spring element (18) is a rod, wire, chain or cable device.

8. An arrangement according to any of claims 1-6, characterised in that the support and/or spring element (18) is a spring device.
