   PLATEAU CHARGEUR ET DECHARGEUR AUTOMATIQUE. 



   La présente invention se rapporte à un plateau qui, par sa propulsion, s'engage sous une charge et l'amène complètement et automatiquement sur lui. Ceci est obtenu par un dispositif mécanique qui permet d'engager sous la charge un élément mobile dont le mouvement est commandé par le mouvement pro pulseur du plateau et dont la direction est inverse de celle du plateau; le mouvement d'avancement du plateau et celui de l'élément mobile s'effectuant avec des vitesses égales. 



   La présente invention est caractérisée par l'emploi simultané et la disposition d'assemblage des éléments suivants représentés au dessin établi pour une charge de 5 kgs/dm2.:
1 ) deux ou plusieurs poutres cantilever (P) de section convenable sont encastrées dans un châssis métallique (M) et sont recouvertes d'une tôle métallique (T) ou en autre matière appropriée.

   Cette tôle est pourvue d'une ou de plusieurs rainures (R) et porte des rouleaux (B) tournant dans leurs logement so
2 ) les poutres reposent sur des roues ou sur des rouleaux de propulsion (W) qui par friction ou par engrenage entrainent dans leur mouvement,soit une courroie sans fin (C), soit un système de câble sans fin ou de chaînes sans fin -. par exemple la courroie (C) est disposée au dessus de la tôle (T) recouvre les rouleaux libres (B) puis s'enroule, partiellement, sur les rouleaux d'entraînement (A) et (W) et sur le ou les tendeurs de courroie (D), puis sur le rouleau (H) et rejoint son autre extrémité. 



   3 ) chaque poutre cantilever peut être munie à son extrémité d'un couteau ou éperon (E) à faible coefficient de frottement obtenu par adjonction de billes ou de rouleaux. Ce couteau ou éperon (E), en acier spécial ou en autre matière, borde le plateau à   l'avant.

 les chaines, ainsi qu'un dispositif de freinage automatique bloquant les mouvements des éléments du. plateau, peuvent être prévus et disposés, par exemple, sous le plateau, dans l'intervalle libre séparant les poutres principale Se 
5 ) le mouvement de propulsion peut être produit, soit par le   simple   roulement de l'appareil sur le sol ou sur appui fixe, soit par en- traînement mécanique. 



   6 ) la suspension du châssis (M) porteur du plateau est prévue de telle façon, que par rotation autour d'un axe central (0), le parallé- lisme   du   couteau-éperon (E) et de la surface d'appui de la charge, est assu- réo 
Le fonctionnement de l'appareil est le suivant : le plateau étant posé sur le sol est animé, par poussée, d'un mouvement dans le sens de la flèche (F), l'éperon (E) s'engage sous la charge qu'il   soulève,,   et qui, a- près roulement sur rouleaux (S) supérieurs de l'éperon, se trouve en prise avec la courroie (C) dont le mouvement suivant flèche (F 1) l'entraîne jus- qu'à ce qu'elle se trouve complètement sur le plateau.

   Le déchargement d'u- ne charge, à un endroit déterminé, s'effectue automatiquement par la simple action, en sens inverse, de la flèche (F), la courroie entraînant, de ce fait, la charge dans le sens opposé à (F 1).

   AUTOMATIC CHARGER AND UNLOADER PLATE.



   The present invention relates to a plate which, by its propulsion, engages under a load and brings it completely and automatically on it. This is obtained by a mechanical device which makes it possible to engage under the load a movable element whose movement is controlled by the propelling movement of the plate and whose direction is opposite to that of the plate; the movement of advance of the plate and that of the movable element being effected at equal speeds.



   The present invention is characterized by the simultaneous use and the assembly arrangement of the following elements shown in the drawing established for a load of 5 kgs / dm2 .:
1) two or more cantilever beams (P) of suitable section are embedded in a metal frame (M) and are covered with a metal sheet (T) or other suitable material.

   This sheet is provided with one or more grooves (R) and carries rollers (B) rotating in their housing so
2) the beams rest on wheels or on propulsion rollers (W) which by friction or by gearing lead in their movement, either an endless belt (C), or a system of endless cables or endless chains - . for example the belt (C) is placed above the sheet (T) covers the free rollers (B) then winds, partially, on the drive rollers (A) and (W) and on the tensioner (s) belt (D), then onto the roller (H) and join its other end.



   3) each cantilever beam can be fitted at its end with a knife or spur (E) with a low coefficient of friction obtained by adding balls or rollers. This knife or spur (E), in special steel or other material, borders the plate at the front.



   40) tensioning devices for the belt, cables or

 <Desc / Clms Page number 2>

 chains, as well as an automatic braking device blocking the movements of the elements of the. tray, can be provided and arranged, for example, under the tray, in the free space between the main beams Se
5) the propelling movement can be produced either by simply rolling the device on the ground or on a fixed support, or by mechanical drive.



   6) the suspension of the frame (M) carrying the plate is provided in such a way that by rotation about a central axis (0), the parallelism of the knife-spur (E) and the bearing surface of the load is insured
The operation of the device is as follows: the platform being placed on the ground is driven, by pushing, with a movement in the direction of the arrow (F), the spur (E) engages under the load that 'it lifts ,, and which, near the upper roller bearing (S) of the spur, is engaged with the belt (C), the movement of which according to arrow (F 1) drives it until what it sits completely on the shelf.

   The unloading of a load, at a determined place, is carried out automatically by the simple action, in opposite direction, of the arrow (F), the belt driving, therefore, the load in the direction opposite to ( F 1).

Claims

Use: loading and unloading of cement in bags in the cement industry, raw materials or in bales in the textile industry, etc. ABSTRACT : 1) a metal plate or other material supported by metal beams or not of suitable section provided with one or more rollers or translation wheels of the plate, these meshing directly or indirectly by teeth or by friction with a driven roller or a driven belt which can move between the beams, under the plate, and close on itself passing, through openings (R), above the plate, This belt, driven by a movement opposite to that of the driving roller, is supported by rollers or balls placed on or crimped on the plate. Plate fitted or not with a brake locking the moving parts in place.

2) a plate made as in 1) above, but whose rollers (W) attack one or more chains, or one or more cables, or another latching device in order to perform the movements indicated .

3) a plate made as in 1) above but whose rollers (B) directly support the load and are driven by pinions, chain, cable or rack.

4) a plate made as in 1) above, whether or not provided with a spur knife (E) which can engage under the load. This spur can be lined on its lower face and on its upper face with elements suitable for reducing its coefficient of friction by the use, for example, of balls or rollers.

5) a plate constituted as in 1) above, provided with a drive device, either mechanical, electrical or hydraulic, making it possible to obtain the movements necessary for the operation of the plate and its components, when the latter it does not touch the ground, or has no support on a fixed body.

6) a plate made as in 1) above, supported by a frame-apron mounted on a mechanical machine allowing the alignment of the alignments of the spur of the plate and of the load bearing surface. <Desc / Clms Page number 3>

7) a plate made as in 1) above, provided with a tensioning system for cables, chains or belts.

8) different arrangements can be made, and different materials can be used, without departing from the present invention, for example, the materials of the different parts can be other than metals, -if they have the qualities of mechanical resistance, physical and chemicals needed. For example, the beams, instead of being made of steel, can be made of reinforced synthetic material or the like, the belt can be either steel, or leather, or synthetic material, or the like, etc.

The principle of the apparatus forming the object of the present invention resides in the fact of simultaneously operating two movements, the first of which advances under the load, the second, in the opposite direction to the first, causing the load on the load. plate, and that, without there being translation, but only raising of the load and vice versa for the discharge of the plate. This principle alone should serve as a criterion.
