Title; Automatic binding device for guide wires for plants, in particular for hops

The invention relates to an automatic binding device for guide wires of plants, especially for hops.

When hanging up hop guide wires, which is one of the most difficult spring jobs in hop gardens, suspension wires have mainly been used so far, to which the hop guide wire must first be tied, whereupon the hook together with the hop guide wire is hung on a row wire in the hop garden, which is mostly done by hand. There are also

such types of semi-automatic hanging devices known for hop guide wires, which mostly use the same suspension hooks. This complicates them Construction of the suspension device and complicates the later mechanized hop-picking, as the hooks often get into the picking drums, whose picking fingers break off and thus cause a reduction in the quality and yield of the hop harvest.

For this reason, the demand has recently been made to fix the guide wires directly by tying them to the row wire of the hop framework, i.e. h _e without hanging hook to hang up. If knotters are used for this work, the guide wire must first be inserted into them and pulled through the knot organ, which only then carries it up and attaches it there. The insertion and pulling of the guide wire into the actual knotter has so far had to be carried out by hand, which reduces the achievable performance of the machine and makes it dependent on the skill and effort of the operator.

The invention is based on the object of eliminating these disadvantages by creating a fully automatic device, welohe the guide wire, which is a for the beginning of the work is always inserted into the facility, then even after being carried up on the row wire on these

and which is able to repeat this work without further manual insertion of stats · The The facility therefore offers the prerequisite for a significant increase in the work performance of the entire suspension device, whereby they depend on the skill of the operator and any manual labor completely eliminated.

This object is achieved according to the invention in that above a fixed frame provided with a knife a movable frame is arranged which carries a hollow shaft through which the guide wire passes, wherein at the upper end of the hollow shaft an arm firmly connected to the hollow shaft and a rocker arm above the hollow shaft is provided, under the end of which the guide wire passes to the knife.

An embodiment of the invention is shown in the drawing and is described in more detail below. It demonstrate:

Fig. 1 is a kinematic diagram of the device in front view and

Fig. 2 is an elevation of the actual construction of the device.

109884/1208

The device consists of a movable frame 1 in which a threaded rotatable hollow shaft 2 is mounted at its lower end, on which a screw nut 3 connected to a lifting rope 4 or a chain, belt or the like is movably arranged. The screw nut 3 slides on a guide rod 5 _f which prevents the rotation of the screw nut and is therefore firmly connected at its lower end to the movable frame 1, while the upper end of the guide rod 5 is in an articulated connection with a rocking lever 6. This lever is also articulated with a tie rod 7

The lower part of the tie rod 7 passes through the movable frame 1, in which it is displaceable is arranged. The rocker arm 6 is connected to the movable frame 1 by a spring 8. on a fixed frame 9, which is provided with a stop 16 for the pull rod 7, is a in its upper part Movable knife 10 articulated on a rod 11 is pivotably mounted. The rod 11 is with one to the fixed frame 9 articulated lower lever 12 in an articulated connection.

Above the arm of the lower lever 12 remote from the rod 11, a stop 13 is attached to the

- 5 -109884/1206

movable frame 1 is firmly connected. An arm 14 is attached to the upper part of the hollow shaft 2. Through the with a screw thread provided hollow shaft 2, a guide wire 15 is pushed through, which is also below the lower End of the rocker arm 6 and between the movable knife 10 and the fixed frame 9 passes. Instead of the screw nut 3 can, for example, on the hollow shaft 2 by means of a transmission (e.g. gear transmission) be attached to the rope 4 connected gear (not shown).

The device according to the invention works as follows:

Before starting work, the guide wire 15 is pushed up through the hollow shaft 2 from below and at the top The end of the hollow shaft 2 is fastened by bending by means of the rocker arm 6, the screw nut 3 being in located near the upper end of the hollow shaft 2. (In Fig. 1 shown in dashed lines). After commissioning the hanging machine, not shown, begins to be attached to the lifting rope 4 of the device movable frame 1 to move upwards, wherein the guide wire 15 is also carried up.

After the upper turning point is reached, the rope 4 begins to move downwards with the knotter, the

1098ÖW1206

Rocker arm 6, against which the guide wire 15 is supported, on the row wire, not shown of the hop frame rests and the movable frame with the guide wire 15 remain on the row wire of the hop frame hang on the rocker arm 6. The rope 4 moves continuously downwards and guides the nut 3 with, through the action of which the hollow shaft 2 provided with a screw thread is set in rotation The arm 14 strikes the end of the guide wire and rotates (finely) it around the one emerging from the hollow shaft 2 Part of the guide wire 15 after the nut 2 rests on the movable frame 1, is exerted by the further movement of the rope 4, a pressure on the movable lame 1, against which the Tensile force of spring 8 acts

As soon as the pressure of the nut 3 against the movable frame 1 reaches a higher value than the preload of the spring 8, the rocker arm 6 swings out and the movable frame 1 begins to move again together with the rope 4, with the attached wire on the row wire Guide wire 15 gets stuck · During the downward movement, the movable frame 1 is carried along by the corresponding movement of the cable 4 and is simultaneously guided through the guide wire 10 passing through the hollow shaft 2.

■ - 7 109884/1200

Before the lower turning point is reached, the movable frame 1 sinks either by its own weight or by the train of a spring, not shown, down so that the nut 3 again to the top the hollow shaft 2 arrives. In the lower turning point or close gate of its achievement hits against the fewten Frame 9, first of all, the tie rod 7. By this impact and by means of the spring 8, the rocker arm 6 is pivoted out. During this movement, the guide wire 15 is bent again, the lower end of the just suspended Guide wire 15 passes between the knife 10 and the fixed frame 9.

So that when the tie rod 7 is hit, it does not lead to a premature Displacement of the screw nut 3 and thereby the rotation of the hollow shaft 2 provided with the arm 14 comes, the knotter can with any securing device, not shown, against displacement of the nut 3 are equipped, such. B, with an elastic planchette or a spring-loaded lever, which are pressed against the nut 3. When the lower turning point is reached, the stop hits 13 on the lower lever 12, which actuates the movable knife by means of the rod 11, whereby the guide wire is cut off. After cutting off, the movable frame 1 with the rope 4 starts up again to move and the whole process repeats itself.

As already mentioned, the rotation of the hollow shaft 2 not just by shifting the nut 3 are caused along the thread of the hollow shaft 2, but the hollow shaft 2 does not need any thread at all to be provided and can also by means of a translation by the movement of the rope 4 in Rotation are offset, z. B. by means of a gear attached to the hollow shaft 2.
