Abstract
There is provided a method and apparatus whereby pieces of timber are sorted into lots on supporting arms which are suspended by flexible and extensible members. As the timber is added, the arms are lowered and finally extend down to a conveyor apparatus. The arms then open to discharge the timber on to the conveyor apparatus and are then drawn up, are closed and reach the start position where a new lot of timber is received.

A method for the use of timber sorting compartments, in which method a sorting compartment is filled with timber pieces (a,), after which the sorting compartment is opened and the accumulated timber lot (T.sub.2) is allowed to discharge onto take-up equipment (15), by means of which the timber lot is then carried on to be further processed, after which the compartment is closed to be ready to receive the next timber lot;
- wherein the method comprises the steps of:
- accumulating the timber lot (T.sub.2) upon rigid supporting arms (12a,12b) suspended and extended by pairs of flexible suspending means (10a,10b), these means being located on both sides of the accumulated timber lot (T.sub.2);
- lengthening the pairs of flexible suspending means (10a,10b), then opening or allowing the supporting arms (12a,12b) to open;
- lifting the supporting arms (12a",12b") independently and by separate paths to a top position by shortening the pairs of flexible suspending means (10a,10b);
- locking the supporting arms (12a"',12b"') to form a closed bottom of the compartment for receiving pieces of the next timber lot, and repeating the phases for the next timber lot.
A sorting compartment of a timber sorting installation, comprising:
- flexible supporter means (10a,10b), connected at the top ends thereof with winding equipment, rigid supporting arms, fastened to lower ends of said supporters, locking means (14,19,35b,36,37) connected to adjacent ends of said supporting arms, a take-up conveyor,
- means (16) positioned beneath the level of the take-up conveyor (15) for unlocking said locking means, and guide means at the top of the compartment (23,27) for guiding said supporting arms so that said supporting arms (12a"',12b"') are locked by said locking means in a position in which they form the closed bottom of a compartment when the supporting arms are in their top position.
A sorting compartment of a timber sorting installation, comprising:
- flexible supporter means (10a,10b), connected at the top ends thereof with winding equipment, rigid supporting arms (12a,12b), fastened to lower ends of said supporters, locking means (14,19,35b,36,37) connected to adjacent ends of said supporting arms, a take-up conveyor,
- means (16) positioned beneath the level of the take-up conveyor (15) for unlocking said locking means, and guide means at the top of the compartment (23,27) for guiding said supporting arms (12a,12b) so that said supporting arms (12a"',12b"') are locked by said locking means in a position in which they form the closed bottom of a compartment when the supporting arms are in their top position;
- and
- flanges (35a,35b) at the inner ends of respective supporting arms and corresponding flanges (25) associated with the outer ends of said supporting arms (12a,12b) in an oblique position relative to the longitudinal direction of the supporting arms (12a,12b), so that the supporting arms are locked, pair by pair, to form an acute angle (a), seen in profile.
