DOUBLE-KNOT TWINE-KNOTTER UNIT FOR LARGE BALE PRESSES HAVING A PLURALITY OF DOUBLE-KNOT TWINE KNOTTERS COMBINED ON ONE KNOTTER DRIVE SHAFT

摘要

A double-knot twine-knotter unit for a large bale press with twine tying having a plurality of double-knot twine knotters (10) combined on one knotter drive shaft. Each double-knot twine knotter (10) comprises at least one knotter drive disc (20), a knotter chassis (12), a knotter assembly (30) and a blade lever (4). The knotter drive disc (20) is fastened fixedly on the knotter drive shaft (14) which can be driven about its axis, so as to rotate with it. The knotter chassis (12) is assigned to the knotter drive disc (20) in such a way that the knotter chassis (12) is held in a spatially stationary manner at one end with regard to a press channel (P) and at the other end by the knotter drive shaft (14). The knotter chassis (12) carries a knotter assembly (30), which forms two knots following one another, and the blade lever (4) which is driven by a cam track (26) of the knotter drive disc (20). The knotter assembly (30) comprises at least one twine holder (8) which is driven by a first drive toothing system (22) of the knotter drive disc (20), and a knotter hook (6) which is driven by a second drive toothing system (24) of the knotter drive disc (20). The knotter assembly (30) is arranged offset axially overall with regard to the hub (18) of the knotter drive disc (20) and the drive shaft-side end of the knotter chassis (12). Said knotter assembly (30) is arranged so as to overlap in the axial direction of the knotter drive shaft (14) with the knotter drive disc (20) of the adjacent double-knot twine knotter (10) on a part length of the knotter assembly.
