Abstract

The invention relates to the automatic mounting, at regular intervals, of drips on irrigation pipes. According to the invention, two irrigation pipes 1 are dealt with in parallel and in two principal phases which consist, firstly, in piercing 1 and in simultaneously picking up the drip 2 by a single movement of a table 4 and, secondly, in fitting 2 into the hole made on 1 in the previous phase after 4 has moved over the desired length. The finished product is intended for irrigating crops and, more particularly, trees.

Description

La présente invention a pour objet le montage automatique, à intervalles réguliers, de goutteurs sur des tubes d'irrigation et une machine pour la mise en oeuvre de ce procédé. The present invention relates to the automatic mounting, at regular intervals, of drippers on irrigation tubes and a machine for the implementation of this process.

Dans la demande française NO 84 14744 relative à une "machine automatique.pour le montage de microtubes sur des tubes d'irrigation, l'actuel demandeur avait automatisé, selon un dispositif original, des tâches qui jusqu'alors étaient effectuées manuellement et dans des conditions d'utilisation non acceptables. In French application NO 84 14744 relating to an "automatic machine. For the mounting of microtubes on irrigation tubes, the current applicant had automated, according to an original device, tasks which until then had been carried out manually and in conditions of use not acceptable.

Dans la présente demande d'invention, le demandeur a également conçu une machine, d'un principe totalement différent, permettant de pallier les inconvénients d'un travail manuel irrégulier et lent. En effet, l'automatisation du perçage des trous destinés à l'emboStement des goutteurs permet une mise en place plus régulière et fiable évitant ainsi toute fuite intempestive qui pourrait être néfaste aux cultures. De plus le principe choisi pour la tête du travail permet dune part de traiter deux tubes d'irrigation en parallèle et simultanément, et d'autre part d'accrottre l'efficacité de celle-ci. In the present invention application, the applicant has also designed a machine, of a completely different principle, making it possible to overcome the drawbacks of irregular and slow manual work. Indeed, the automation of the drilling of the holes intended for the nesting of the drippers allows a more regular and reliable installation thus avoiding any untimely leakage which could be harmful to the cultures. In addition, the principle chosen for the work head makes it possible on the one hand to treat two irrigation tubes in parallel and simultaneously, and on the other hand to increase the efficiency thereof.

Selon la présente invention, le procédé de mise en place des goutteurs sur les tubes d'irrigation s'effectue selon deux phases principales : - la première consistant, par un seul déplacement vertical de la table support d'une perceuse et d'une pince, à percer le tube d'irrigation et à prélever simultanément le goutteur de sa glissière d'alimentation - la deuxième consistant, après déplacement horizontal de la table support d'une longue#ur égale à l'entre-axe existant entre la perceuse et la pince, à embosser le goutteur dans le trou effectue sur le tube d'irrigation dans la phase précédente. According to the present invention, the method of placing the drippers on the irrigation tubes is carried out according to two main phases: - the first consisting, by a single vertical movement of the support table of a drill and a clamp , to pierce the irrigation tube and simultaneously remove the dripper from its feed slide - the second consisting, after horizontal displacement of the support table of a long # ur equal to the center distance between the drill and the pliers, to emboss the dripper in the hole made on the irrigation tube in the previous phase.

Ainsi, par un déplacement vertical et un autre horizontal de la table, on peut effectuer les tâches de perçage du tube, de prise et d'embottement des goutteurs. Thus, by moving the table vertically and horizontally, it is possible to carry out the tasks of drilling the tube, taking and sticking the drippers.

Selon une autre caractéristique du procédé, deux tubes d'irrigation sont traités simultanément par un seul déplacement de la table support qui comporte deux perceuses et deux pinces. According to another characteristic of the process, two irrigation tubes are treated simultaneously by a single movement of the support table which comprises two drills and two pliers.

Grâce à cette caractéristique, on peut doubler les caden ces de travail de la machine. Thanks to this characteristic, the working caden ces of the machine can be doubled.

D'autres caractéristiques et avantages apparattront à la lecture de la description détaillée qui suit d'un mode de réalisation préféré de l'invention donné ici à titre d'exemple et représenté aux dessins annexés. Other characteristics and advantages will appear on reading the following detailed description of a preferred embodiment of the invention given here by way of example and shown in the accompanying drawings.
