Description

The invention relates to a knotter apparatus according to the Deering system for balers, mower binders, Plant bundle machine or the like with a rotating Knotter hook, with one pivotably mounted on the knotter hook, via one on a guide curve on the knotter frame unrolling roll controllable knotter tongue and with a spring pressure standing, having a conductive path for the knot tongue rolls and these out. ' part of the knotter hook rotation Hook-lock (pressure thumb) pressing against the guideway.

The hook closer has the task of turning of the knotter hook at a certain point by pressing the knotter tongue. which is formed from the knotter tongue and the knotter hook, to close and thus the formation of the knot initiate. The knotting process consists of a series of processes that take place in a certain Zcittakt expire. Should faults occur during the knotting process occur in the Prcßkanal through which the Preßkolbcn in could be damaged in any way, so was the case with the previously known press guides so-called "piston stop" for the standstill of the pressure piston. and / was at a point from which a There is still a sufficient safety distance to the binding needles that may still be in the press room. which lead the twine across the press channel is present. The stop of movement of the plunger was made by shearing off a shear pin in the Shark drive disk of the baler causes. To For the shear lift, the piston of the flywheel was usually turned back by hand. because then the piston slab is also in its starting position returns. Any malfunctions in the press channel could then be investigated. Due to the only in A single-directional coupling remained the drive for the knotting apparatus and binding needles disengaged when the flywheel is turned back. Only when turning in the normal drive direction was then the movement of the plunger is synchronized again with the rotation of the binding screw from a certain point.

In recent times, efforts have been made to drive the plunger and the binding shaft by appropriate means Connecting links to be connected to one another so that with a backward movement of the press piston without prior to reaching a dead position the binding shaft "· rotates in the opposite direction at the same time. This requires a binding shaft coupling that works in both directions of rotation and a knotter apparatus, which allows both directions of rotation.

However, the previously known knotter apparatus based on the i ⁽⁾ Deering system only allow the knotter tongue roll to pass through in one direction. During reverse rotation of the bill hook, it could happen that the freely oscillating knotter tongue came with its role on the outer side of the hook closer to ι ⁵ system and the further reverse rotation of the K blocks nüpferhakens

The object of the invention is to provide a knotter apparatus

to be designed according to the Deering system in such a way that the knotter hook can be rotated in both directions of rotation.

To solve this problem is according to the invention on Hooks close an additional track for the reverse rotation of the bill hook, which corresponding to the position of the knotter tongue role when the knotter tongue swings out as far as possible

In the reverse rotation of the knotter ungenrolle not hit / as be ^'f the known embodiments on the hook closer to the outside. but ^{he) ()} passes so that the Knüpfhaken be allowed into the additional interconnect in the reverse direction in the usual way and rotate the Knüpfcr / ugenrolle after they traveled a certain distance below the Hakenschlicßer against the Arbeitsrichiung '' has, by itself runs into the correct channel for the working direction.

In other types of knotter apparatus, such. B. McCormick. Piano etc. occurs the problem of F.rfindung does not appear and the possibility of reversing the direction of rotation is known per se.

An exemplary embodiment of the invention is shown in the drawing.
