Abstract

The invention relates to the device for guiding a truck, serving as a work station. This device avoids getting the truck down in order to guide it. This guidance device makes it possible, on the one hand, to guide the truck automatically with the aid of a front guide head (R5) in the event of forwards operation, which is applied through the use of a lever (R2), of a linkage (R3) and of an arm (R1) onto a single non-supporting rail (R6) and thus guides the guiding wheels (R8). Simultaneously, the rear guide head (R5) detaches from the rail (R6). In the event of operating in reverse the principle is reversed. This guidance device makes it possible, on the other hand, to eliminate the automatic guidance of the truck by means of a neutral position of the guide heads (R5), both detached from the rail (R6): the steering wheel (R7) then orientates the guiding wheels (R8). The device according to the invention is particularly intended for trucks acting as a work station in crops grown in rows.

Description

Dispositif de guidage pour chariot avec rail ou sans rail, quelque soit le sens de déplacement du chariot.Guide device for trolley with rail or without rail, whatever the direction of movement of the trolley.

La prénte invention concerne un dispositif de guidage d'un chariot servant de poste de travail* avec rail ou sans rail. Ce dispositif évite de descendre du chariot pour le guider. Il fonctionne dans n'importe quel sens de ddplace- ment du chariot. The present invention relates to a device for guiding a carriage serving as a work station * with rail or without rail. This device avoids getting off the carriage to guide it. It works in any direction of movement of the carriage.

Dans les cultures alignées, il existe un problème li au déplacement du per- sonnel d'intervention. En effet, pour libérer le personnel, les engins motorisés utilisés doivent être autoguidés à l'intérieur d'une zune d'intervention, soit entre deux rangs de cultures. Le passage d'une mone d'intervention b une autre zone d'intervention, se fait par suppression de l'autoguidage. In aligned cultures, there is a problem related to the movement of intervention staff. To free the staff, the motorized vehicles used must be self-guided within an intervention zone, that is to say between two rows of crops. The transition from an intervention zone to another intervention zone is done by eliminating the autoguiding.

À ce Jour, l'engin utilisé est un chariot guidé par un système de rails porteurs. To date, the machine used is a trolley guided by a system of supporting rails.

Ce système ne donne pas pleinement satisfaction pour deux raisons .ssentielles -d'une part l'encombrement dù
au nombre de rails necessaires
-à leur dimension à B leur hauteur par rapport au sol
à B la multiplication dea porte-rails et des traverses de pazallélisme - d'autre part, le m vienent du chariot en passant d'une zone d'intervention à une autre. Pour cela en effet, l'opérateur doit descendre du chariot servant de poste de travail et agir sur celui-ci à la manière du pousse-pousse ou de la brouette pour le remettre sur un système de rails porteurs.This system is not fully satisfactory for two essential reasons - firstly the bulk
the number of rails required
-to their dimension at B their height from the ground
at B the multiplication of rail carriers and crosspieces of pazallelism - on the other hand, the movement comes from the carriage passing from one intervention zone to another. For this indeed, the operator must get off the cart serving as a work station and act on it like a rickshaw or wheelbarrow to put it back on a system of carrier rails.

Le dispositif suivant l'invention, permet le guidage des roues directrices avec un unique rail non porteur (autoguidage) ou sans rail de guidage (sans autoguidage), quelque soit le sens de déplacement du chariot;
- b guidage avec rail (autoguidage) par l'intermédiaire d'un levier, l'utilisateur agit simultanément sur deux bras mobiles reliés aux roues directrices par articulation et portant chacun une tête de guidage. Cette action a pour effet d'appliquer sur le rail la tête de guidage située du coté du sens de la marche, tout en décollant du rail la teste de guidage située du coté opposé au sens de marche.The device according to the invention allows the guide wheels to be guided with a single non-load-bearing rail (autoguiding) or without guide rail (without autoguiding), whatever the direction of movement of the carriage;
- b guide with rail (autoguiding) by means of a lever, the user acts simultaneously on two mobile arms connected to the steered wheels by articulation and each carrying a guide head. This action has the effect of applying to the rail the guide head located on the side of the direction of travel, while taking off from the rail the guide test located on the side opposite to the direction of travel.

- Le guidage sans rail (sans autoguidage): par le même levier, l'utilisateur agit sur les deux bras portant les tStes de guidage qui se décollent alors simul- tannent du rail et periattent dès lors d'assurer le guidage du chariot par l'in- termédiaire d'un volant qui commande l'orientation des roues directrices. - Guidance without rail (without autoguiding): by the same lever, the user acts on the two arms carrying the guiding tStes which then peel off simultaneously from the rail and therefore periattent ensure the guiding of the carriage by l 'via a steering wheel which controls the orientation of the steered wheels.

Selon une autre forme de réalisation , levier et volant peuvent constituer une même commande.  According to another embodiment, lever and flywheel can constitute the same control.

En références à ces dessina, le dispositif de guidage du chariot comporte selon la figure 1, un levier (rep. 2) manié par l'utiliaAteur permet trois posi tions liées au déplacement AV, N1, Ar et agit sur une tringle (rep.3) ou cable (rep.3) qui transmet le mouvement au bras (rep.1). Les têtes de guidage (rep.5) portés par les bras s'appliquent sur le rail (rep.6) ou s'en détachent selon le cas. Le volant de commande (rep.7) permet l'orientation des quatre roues directrices; selon la figure 2 (2a), le levier (rep.2) en narche AV, le chariot se déplace dans le sens de la flèche.La tête de guidage (rep. 5) à l'avant du chariot est appliquée sur le rail (rep.6). La tête de guidage à l'arrière du chariot est détachée du rail selon la figure 2 (2b), le levier (rep.2) en position marche arrière (AR), le chariot se déplace dans le sens de la flèche.
