A wire strapping or tying device (46) is provided having a rotatable pinion-type knotter assembly (56) for twist-knotting of a pair of adjacent wire sections (50a, 50b), together with a shiftable knotter cover (266) movable between a home position for maintaining the sections (50a, 50b) within the assembly (56) and a remote knotter access position allowing ready access to the knotter assembly (56). The cover (266) is supported by arms (268, 270) which are pivotal about an axis spaced from and generally parallel with the cover (266). The cover (266) may be manually shifted to the remote knotter access position through an arc of at least 45°. Also, the knotter assembly (56) includes a primary body (128) supporting a rotatable, slotted knotter pinion (178). The body (128) is pivotally secured to frame plates (68, 70), allowing the body (128) to be pivoted to a convenient position for servicing of pinion (178). Preferably, a mechanical operator assembly (198) is employed to sequentially operate all of the device components in a precise, timed sequence. A single drive assembly (196) preferably in the form of a piston and cylinder assembly (200) is used to actuate the assembly (198).
In a knotting device including a rotatable knotter operable to twist-knot a pair of adjacent wire sections, and a cover located adjacent said knotter for maintaining the wire sections within the knotter during feeding and knotting operations, the improvement which comprises a mount for said cover permitting the cover to be pivoted away from said knotter to a knotter access position remote from said wire-maintaining position and through a pivot arc of at least about 90°.
In a knotting device including a knotting assembly having a gripper for selectively gripping one of two adjacent wire sections, a rotatable knotter operable to twist-knot the two adjacent wire sections, a cutting element for cutting of the other of said adjacent wire sections after twist-knotting of the sections and a shiftable cover located adjacent said knotter for maintaining the wire sections within the knotter during feeding said twist-knotting and thereafter movable to a wire-clearing position permitting passage of the twist-knotted wire sections from the knotter, the improvement which comprises an operator assembly for timed operation of said gripper, knotter, cutting element and cover, and a single drive assembly coupled with said operator assembly for effecting said timed operation.
In a knotting device including a rotatable knotter operable in one position thereof to twist-knot a pair of adjacent wire sections, and a cover located adjacent said knotter for maintaining the wire sections within the knotter during feeding and knotting, the improvement which comprises a mount for said knotter permitting the knotter to be pivoted from said one position to an access position allowing servicing of the knotter.
