• the present invention relates to a portable electric tying machine for the binding of plants, in particular the binding of the vine.
• the field of the invention is the field of portable electric tying machines for the binding of plants, in particular the binding of the vine.
• tying machines are known for tying plants, in particular tying vines.
• tying machines comprise a tying head, a mechanism for twisting a wire on a branch to be tied and a system for driving said wire into the tying head and up to a position to be twisted.
• the current portable electric tying machines for binding plants are not without limitations. Indeed, current tying machines have reliability problems. For example, it is common for the tie wire to get stuck in the body of the tying machine. The tying machine therefore needs to be maintained and repaired regularly.
• An object of the present invention is to remedy at least one of the aforementioned drawbacks.
• Another object of the present invention is to provide a more reliable tying machine allowing a better work rate.
• the invention makes it possible to achieve at least one of these goals by means of a portable electric tying machine for the binding of plants, in particular the binding of the vine, comprising:
• tie head disposed at a distal end of said body, said tie head comprising a guide path for a tie wire
• said drive system comprises:
• the invention thus proposes a tying machine comprising two separate mechanisms for driving a tie wire.
• the first mechanism makes it possible to push the tie wire into the tie head and the second mechanism makes it possible to fetch one end of said wire at the level of the tie head and then to pull it to a position to be twisted .
• the first mechanism can only be used to push the tie wire into said tie head and does not have to be used to position the tie wire in the twisting position.
• the first mechanism of the tying machine according to the invention is used to position the wire in the intermediate position but does not need to be used to position the wire in the twisting position.
• the positioning of the wire in the intermediate position known as the pre-loading phase, can thus be carried out between two fasteners and at a moderate driving speed.
• the tying machine according to the invention therefore allows training of the tie wire to be more easily controlled.
• the wire is thus less likely to slip or jam in the drive mechanism.
• the tying machine according to the invention is thus more reliable than the solutions of the art.
• the tying machine comprises a stationary tying head, which allows greater robustness and reduces the maintenance of the tying machine.
• the tie head comes into contact with plants, such as vines, during tying operations, which constitutes a high risk of damage to a mobile tie head, and to its mechanism, in known binders.
• the tying machine provides a second mechanism, distinct from the first mechanism, to fetch one end of said yarn in the tying head and then pull it to a position to be twisted.
• the invention allows positioning of the tie wire in the twisting position more reliably than the solutions of the art pushing the tie wire to the twisting position. Therefore, the tying machine makes tying more reliable.
• the tying machine allows a better rate of work because it is rarer for a user to have to do it twice to properly perform a tie.
• the attachment head may be in the form of a beak, comprising a housing provided for positioning therein a branch of a plant, in particular a vine branch, to be attached.
• a branch to be attached can be positioned in the housing of said spout of the immobile attachment head so that the second mobile mechanism can pick up a attachment wire present in the head. attachment at the intermediate position and bring it into a twisting position without the second mechanism being hindered by said branch to be attached.
• the use of a beak-shaped tie head makes it possible to have a guide path for a tie wire of greater length and thus to reduce the distance between the position intermediate and the so-called twisting position. Consequently, the distance to be traveled by the second mobile mechanism to fetch one end of said yarn at the tie head and then to pull it to the position to be twisted is reduced. Thus, the time required for the second mechanism to fetch one end of said yarn at the tie head and then to pull it to the position to be twisted is also reduced.

• a second roller called pressure roller, designed to press said tie wire against said motor roller, so that said rollers drive the tie wire when they are in motion.
• a motorized roller may be a roller driven by a motor of said tying machine.
• a pressure roller can be mounted on a movable support, such as a lever, in contact with a spring bearing on an element of the body of the tying machine so that it applies a force on the movable support and allows said pressure roller to press the tie wire against said motor roller.
• a movable support such as a lever
• a non-limiting example of a mobile support can be a lever, preferably non-removable, designed to pivot sufficiently, for example more than 90°, to allow a user to access the motor roller during a lifting operation. tying machine maintenance.
• the use of a pinch roller makes it possible to accommodate a variation in the distance between a center of rotation of the motor roller and a center of rotation of the pinch roller, which makes it possible to drive the attachment wires of different thicknesses or to drive a thread whose thickness is variable, for example when the latter is twisted.

• the drive roller is capable of driving the pressure roller in a synchronized manner even when the distance between a center of rotation of the drive roller and a center of rotation of the pressure roller varies, in particular to accommodate the passage of a spin in the driven wire.
