Description
La présente invention concerne les dispositifs destinés à immobiliser le bétail pour le solliciter à s'alimenter, que l'on appelle généralement Cornadis. The present invention relates to devices intended to immobilize the cattle to solicit them for food, which is generally called Cornadis.
Ces dispositifs comprennent une barrière, que l'on interpose devant un poste d'alimentation. La barrière est munie d'un bras mobile, que la tête de l'animal doit déplacer pour que ce dernier puisse accéder à sa nourriture ; et le bras est verrouillable pour immobiliser alors la tête de l'animal devant l'aliment. Le verrou est par exemple mis en place ou armé par pivotement sous l'effet d'un mécanisme balancier à contrepoids. These devices include a barrier, which is interposed in front of a feeding station. The barrier is provided with a movable arm, which the animal's head must move so that the latter can access its food; and the arm is lockable to immobilize the head of the animal in front of the food. The lock is, for example, put in place or armed by pivoting under the effect of a counterbalanced balance mechanism.
Jusqu'à présent, ce verrouillage était purement manuel, et L'éleveur devait revenir sur les lieux pour libérer les animaux, lorsqu'il estimait qu'ils avaient passé devant la nourriture un temps suffisant pour s'être alimentés de la manière requise. I1 fallait donc que l'éleveur revienne libérer les animaux après leur repas, ce qui implique un nouveau déplacement, et une sujétion importante sur son emploi du temps. Corrélativement, l'éleveur risquait d'oublier cette tâche, et de laisser beaucoup trop longtemps les animaux en position entravée. Until now, this locking was purely manual, and the breeder had to come back to the scene to free the animals, when he felt that they had passed in front of the food enough time to have eaten as required. It was therefore necessary for the breeder to come back to free the animals after their meal, which implies a new movement, and a significant subjection to his timetable. At the same time, the breeder risked forgetting this task, and leaving the animals in a hampered position for far too long.
La présente invention vient porter remède a ces inconvénients. The present invention remedies these drawbacks.
Selon l'invention, il est prévu un moyen chronométrique pour desarmer ou escamoter le verrou au bout d'un temps prédétermine. According to the invention, a chronometric means is provided for disarming or retracting the lock after a predetermined time.
Dans un mode de réalisation préférentiel, le verrou est armé par relevage du contrepoids, qui est avantageusement pivotant, et le balancier a contrepoids est maintenu en position relevée par un électro-aimant normalement inactif en 1 'absence dElimentation. Ceci évite une immobilisation excessive de 1'animal en cas de disparition du courant secteur. In a preferred embodiment, the latch is armed by raising the counterweight, which is advantageously pivotable, and the counterbalanced pendulum is held in the raised position by an electromagnet normally inactive in the absence of power. This avoids excessive immobilization of the animal in the event of loss of mains power.
De préférence, le moyen chronométrique est un circuit électronique compte-temps, programmable de quart d'heure en quart d'heure. Preferably, the chronometric means is an electronic time-counting circuit, programmable from quarter-hour to quarter-hour.
En pratique, il est prévu une commande manuelle telle qu'un bouton-poussoir pour faire démarrer le comptage de temps. Une seconde commande manuelle permet avantageusement de déverrouiller le contrepoids indépendamment du comptage de temPs. In practice, there is a manual control such as a push button to start the time counting. A second manual control advantageously makes it possible to unlock the counterweight independently of the temPs counting.
D'autres caractéristiques et avantages de l'in vention apparaitront a la lecture de la description détaillée qui va suivre, faite en référence aux dessins annexés, donnés uniquement pour illustrer a titre non limitatif un mode de réalisation préférentiel de l'invention, et sur lesquels
- les figures 1 et 2 illustrent respectiveiilent en élévation et en vue latérale le dispositif selon 1'ir- vention a l'état déverrouillé; et
- les figures 3 et 4 sont des vues qui correspondent respectivement a celles des figures 1 et 2, mais en position verrouillée.Other characteristics and advantages of the invention will appear on reading the detailed description which follows, made with reference to the appended drawings, given solely to illustrate, without limitation, a preferred embodiment of the invention, and on which
- Figures 1 and 2 respectively illustrate in elevation and in side view the device according to the invention in the unlocked state; and
- Figures 3 and 4 are views which correspond respectively to those of Figures 1 and 2, but in the locked position.
Dans un Cornadis, un élément vertical formant bâti 1 reçoit une barrière désignée généralement par 2, et constituée par exemple de deux montants horizontaux 21 et 22, réunis par des éléments verticaux tels que 23 et 24. Un troisième élément vertical 25 est disposé dans sa partie basse comme les éléments 23 et 24, sensiblement jusqu'a la moitié de sa hauteur. A partir de la, il vient par une partie inclinée 26 rejoindre par exemple l'extré- mité supérieure de l'élément 24.Au niveau de son coude entre les parties 25 et 26, cet élément reçoit une char nière 27, qui supporte un élément oblique 30, muni a son tour en partie haute d'une extrémité oblique 31. te poste d'alimentation (non représenté) se place pratiquement entre l'élément 23 et l'élément 25, dans leur partie basse ou ils sont parallèles.Si l'on se reporte a la figure 1, l'animal va donc-introduire sa tête en haut, entre 14élément 23 et l'élément 30, puis i'abaisser pour accéder a sa nourriture, ce qui se traduit par le basculement de l'élément 30 autour de sa charnière 27. I1 est connu d'utiliser alors un verrou qui vient maintenir cet élément 30 en position verticale, comme le montre la figure 3, et l'éleveur vient réaliser le déverrouillage, lorsqu'il estime que l'animal a suffisamment mangé. In a feed fence, a vertical element forming a frame 1 receives a barrier generally designated by 2, and consisting for example of two horizontal uprights 21 and 22, joined by vertical elements such as 23 and 24. A third vertical element 25 is arranged in its lower part like elements 23 and 24, substantially up to half of its height. From there, it comes by an inclined part 26 to join for example the upper end of the element 24. At its elbow between the parts 25 and 26, this element receives a hinge 27, which supports a oblique element 30, in turn provided in the upper part with an oblique end 31. the feeding station (not shown) is placed practically between element 23 and element 25, in their lower part or they are parallel. If we refer to FIG. 1, the animal will therefore introduce its head at the top, between element 23 and element 30, then lower it to access its food, which results in the tilting of the element 30 around its hinge 27. I1 is known to use a lock which keeps this element 30 in a vertical position, as shown in FIG. 3, and the breeder comes to perform the unlocking, when he considers that the animal has eaten enough.
Généralement, le montant horizontal supérieur 21 porte deux anneaux 35 et 36 dans lesquels vient pivoter autour d'un axe horizontal une barre 40 munie de l'élément 42. Cette barre 40 est solidaire d'un balancier transversal 43, muni a son extrémité d'une ou plusieurs charges formant contrepoids 44. Generally, the upper horizontal upright 21 carries two rings 35 and 36 in which a bar 40 provided with the element 42 pivots about a horizontal axis. This bar 40 is integral with a transverse balance 43, provided at its end with one or more loads forming a counterweight 44.
Selon l'invention, le bras 43 porte en plus une pièce métallique 45,destinée à coopérer avec l'electro-aimant 50. According to the invention, the arm 43 also carries a metal part 45, intended to cooperate with the electromagnet 50.
Dans la position illustrée sur les figures 1 et 2, le contrepoids 44 est en position basse, et le basculement du bras 30 est libre. Au contraire, dans la position illustrée sur les figures 3 et 4, le contrepoids 44 est en position haute, et la pièce 45 est sollicitée par l'electro- aimant 50. On voit alors que la butée 42 se situe du côté supérieur de la barre 40i et peut venir immobiliser une tige 32 solidaire de l'extrémité libre de la partie coulée 31 du baiar.cier 30. Ainsi, une fois que l'animal est venu en position d'alimentation, il y demeure bloqué par le fait que le levier 32 vient s'immobiliser sur la butée 42. Ceci demeurera tant que le contrepoids 44 est maintenu en position haute par le jeu de l'électro-aimant 50 sur la pièce 45. In the position illustrated in Figures 1 and 2, the counterweight 44 is in the low position, and the tilting of the arm 30 is free. On the contrary, in the position illustrated in FIGS. 3 and 4, the counterweight 44 is in the high position, and the part 45 is biased by the electromagnet 50. It can then be seen that the stop 42 is located on the upper side of the bar 40i and can come to immobilize a rod 32 secured to the free end of the casting part 31 of the baiar.cier 30. Thus, once the animal has come to the feeding position, it remains blocked therein by the fact that the lever 32 comes to stop on the stop 42. This will remain as long as the counterweight 44 is held in the high position by the play of the electromagnet 50 on the part 45.
De son côté, l'électro-aimant 50 est alimenté par un moyen chronométrique 60, tel qu'un circuit électronique compteur de temps programmable de quart'd'heure en quart d'heure. Un tel circuit peut aisément être réalisé par exemple à l'aide du circuit intégré Xr2240, vendu par la société EXAR. For its part, the electromagnet 50 is supplied by a chronometric means 60, such as an electronic time counter programmable from quarter to fifteen minutes. Such a circuit can easily be produced for example using the integrated circuit Xr2240, sold by the company EXAR.
Si l'on se réfère a la figure 3, un boutonpoussoir 65 permet le démarrage du dispositif chronométrique 60, et l'excitation de l'electro-aimant 50, l'éleveur relevant en meme temps le contrepoids 44 pour qu'il soit maintenu en position haute sous l'effet de l'électro-aimant. Referring to Figure 3, a push button 65 allows the starting of the chronometric device 60, and the excitation of the electromagnet 50, the breeder raising at the same time the counterweight 44 so that it is maintained in the high position under the effect of the electromagnet.
Un ou plusieurs boutons-poussoir 67 permettent la programmation du temps de verrouillage, de quart d'heure en quart d'heure, par exemple jusqu'a une durée maximale de 2 heures.One or more push buttons 67 allow programming of the locking time, from quarter-hour to quarter-hour, for example up to a maximum duration of 2 hours.
Les animaux peuvent alors venir s'alimenter, et y resteront nécessairement le temps choisi par l'éleveur, sans que celui-ci ait a revenir sur les lieux pour déverrouiller les Cornadis. The animals can then come to feed, and will necessarily remain there for the time chosen by the breeder, without the latter having to come back to the scene to unlock the locks.
On notera qu'en cas de disparition du courant secteur, l'électrowaimant 50 perd automatiquement sa force attractive, ce qui. laisse retomber le contrepoids 44, et rend a l'animal toute liberté de consommation. Par ailleurs, si l'éleveur le désire, il peut de toute façon revenir, et agir sur le bouton-poussoir 66 pour désexciter l'électroaimant 50, et libérer l'animal avant le terme du temps programmé. De même, un verrou mécanique ( non représenté) peut assurer le blocage du contrepoids en position haute si dans certains cas l'éleveur ne désire pas se servir du dispositif électrcinique temps programmé. It will be noted that in the event of the mains current disappearing, the electromagnet 50 automatically loses its attractive force, which. drops the counterweight 44, and gives the animal complete freedom of consumption. Furthermore, if the breeder so desires, he can return anyway, and act on the push button 66 to de-energize the electromagnet 50, and release the animal before the end of the programmed time. Likewise, a mechanical lock (not shown) can block the counterweight in the high position if in certain cases the breeder does not wish to use the programmed time electro-kinetic device.
Bien entendu, la présente invention n'est pas limitée au mode de réalisation décrit, mais s'étend a toute variante conforme a son esprit. Of course, the present invention is not limited to the embodiment described, but extends to any variant in accordance with its spirit.
