An arrangement for conveying plates (4) in particular mother plates with or without a deposited metal layer, in an electrolytic metal refining plant, wherein the plates are intended to be conveyed in the conveyor arrangement (25, 50) along at least one horizontal conveyor path with the plates orientated generally vertical and equidistant from one another therealong, characterized in that the conveyor arrangement is of the walking beam kind and includes fixed supports (28, 54) and at least one walking beam (30, 62) having movable supports (31, 67), wherein the walking beam is arranged to move in a cyclic pattern, including a lifting movement in which all the plates conveyed along the path are lifted by the movable supports from their fixed supports in a first position, a forward movement in which all plates are advanced simultaneously one step while resting on their movable supports, a lowering movement in which the plates are placed on fixed supports in a new, second position, and a return movement, wherein the length of one step corresponds to the plate spacing (PI; PII) along the path.
An arrangement for conveying plates (4) in particular mother plates with or without a deposited metal layer, in an electrolytic metal refining plant, wherein the plates are intended to be conveyed in the conveyor arrangement (25, 50) along at least one horizontal conveyor path with the plates oriented generally vertical and equidistant from one another in the conveyor path, characterized in that the conveyor arrangement is of the walking beam kind and includes fixed supports (28, 54) and at least one walking beam (30, 62) having movable supports (31, 67), wherein the walking beam is arranged to move in a cyclic pattern, including a lifting movement in which all the plates supported by the fixed supports are lifted by the movable supports, a forward movement in which all plates are advanced simultaneously one step while resting on their movable supports, a lowering movement in which the plates are placed on fixed supports in a new, second position, and a return movement, wherein the length of one step corresponds to the plate spacing (PI;
A plate conveyor line comprising at least two conveyor paths placed perpendicular to one another, comprising a first conveyor arrangement (25) by means of which the plates are moved essentially vertically perpendicular to the plane of said plates, and a second conveyor arrangement (50) by means of which the plates are moved essentially vertically to the plane of the plates, characterized in that the first conveyor arrangement (25), which includes two walking beams having supports which act against the projections on said plates, functions to deposit the plates in said second conveyor arrangement as the walking beams are lowered, with the bottom edges (57) of said plates resting on supports.
An arrangement for conveying plates (4) in particular mother plates with or without a deposited metal layer, in an electrolytic metal refining plant, wherein the plates are intended to be conveyed in the conveyor arrangement (25, 50) along at least one horizontal conveyor path with the plates oriented generally vertical and equidistant from one another in the conveyor path, characterized in that the conveyor arrangement is of the walking beam kind and includes fixed supports (28, 54) and at least one walking beam (30, 62) having movable supports (31, 67), wherein the walking beam is arranged to move in a cyclic pattern, including a lifting movement in which all the plates supported by the fixed supports are lifted by the movable supports, a forward movement in which all plates are advanced simultaneously one step while resting on their movable supports, a lowering movement in which the plates are placed on fixed supports in a new, second position, and a return movement, wherein the length of one step corresponds to the plate spacing (PI;
An arrangement for conveying generally vertically oriented plates, in particular mother plates with or without a deposited metal layer in an electrolytic metal refining plant, along a horizontal conveyor path wherein the conveying arrangement is a walking-beam conveyor and includes fixed supports spaced apart along the horizontal conveyor path at uniform spacing, a walking beam having movable supports spaced apart therealong at uniform spacing equal to the spacing of the fixed supports, a lifting beam on which the walking beam rests in sliding fashion, a lifting means for lifting and lowering the lifting beam and therewith also the walking beam, a means for restraining the lifting beam against longitudinal movement, and a means for guiding the walking beam to move in a cyclic pattern starting from a position in which the movable supports are below the fixed supports and the plates are in respective fixed supports, the cyclic pattern including a lifting phase in which the walking beam moves upwards from the starting position and the movable supports lift all the plates from their respective fixed supports, an advancing phase in which the walking beam moves longitudinally in a first direction by a predetermined distance equal to said uniform spacing and the movable supports advance the plates simultaneously by said predetermined distance, a lowering phase in which the walking beam moves downwards and the movable supports deposit the plates in respective fixed supports, and a returning phase in which the walking beam moves longitudinally back to said starting position.
An arrangement for conveying generally vertically oriented plates, in particular mother plates with or without a deposited metal layer in an electrolytic metal refining plant, along a horizontal conveyor path wherein the conveying arrangement is a walking-beam conveyor and includes fixed supports spaced apart along the horizontal conveyor path at uniform spacing, a walking beam having movable supports spaced apart therealong at uniform spacing equal to the spacing of the fixed supports, and a means for guiding the walking beam to move in a cyclic pattern starting from a position in which the movable supports are below the fixed supports and the plates are in respective fixed supports, the cyclic pattern including a lifting phase in which the walking beam moves upwards from the starting position and the movable supports lift all the plates from their respective fixed supports, an advancing phase in which the walking beam moves longitudinally in a first direction by a predetermined distance equal to said uniform spacing and the movable supports advance the plates simultaneously by said predetermined distance, a lowering phase in which the walking beam moves downwards and the movable supports deposit the plates in respective fixed supports, and a returning phase in which the walking beam moves longitudinally back to said starting position, and wherein each plate has a substantially horizontal bottom edge and two opposite vertical edges and the plates rest with their bottom edges on the fixed supports when the walking beam is in the first position and the bottom edge of the plate is substantially parallel to said longitudinal direction.
An arrangement for conveying generally vertically oriented plates, in particular mother plates with or without a deposited metal layer in an electrolytic metal refining plant, along a horizontal conveyor path wherein the conveying arrangement is a walking-beam conveyor and includes fixed supports spaced apart along the horizontal conveyor path at uniform spacing, a walking beam having movable supports spaced apart therealong at uniform spacing equal to the spacing of the fixed supports, and a means for guiding the walking beam to move in a cyclic pattern starting from a position in which the movable supports are below the fixed supports and the plates are in respective fixed supports, the cyclic pattern including a lifting phase in which the walking beam moves upwards from the starting position and the movable supports lift all the plates from their respective fixed supports, an advancing phase in which the walking beam moves longitudinally in a first direction by a predetermined distance equal to said uniform spacing and the movable supports advance the plates simultaneously by said predetermined distance, a lowering phase in which the walking beam moves downwards and the movable supports deposit the plates in respective fixed supports, and a returning phase in which the walking beam moves longitudinally back to said starting position, and wherein the arrangement further comprises upper and lower stop elements which limit vertical movement of the walking beam.
