Abstract

Transport device with cyclic movement for granular, powder or pasty products. The invention relates to a device permitting transportation of movable products by means of an assembly of combined systems comprising a flexible blade 5 and a rigid comb 4, this system being integral with a movable chassis 2 driven in a cyclic to-and-fro movement through a drive member 1. In the movement according to position 9, the flexible blade rises over the material whilst the comb is displaced in the material without displacing it significantly. In the movement according to position 10, the end of the flexible blade is embedded in the material, is displaced progressively towards the comb in order finally to bear against it completely. In this configuration, the combined inertia of the blade and of the comb gives rise to the displacement of the material (positions 11 and 12). The device according to the invention is intended particularly for transporting granular or powder or pasty products.

Description

La présente invention concerne un dispositif de transport par mouvement cyclique de produits granuleux ou en poudre ou pateux.  The present invention relates to a device for the transport by cyclic movement of granular or powdered or pasty products.

Dans les systèmes généralement existants utilisant des éléments impulseurs, il est fait appel à des volets mobiles aptes à pivoter dans un sens autour d'axes transversaux et des butées fixes ou mobiles par rapport aux dits axes. In generally existing systems using impeller elements, mobile shutters capable of pivoting in one direction around transverse axes and fixed or mobile stops relative to said axes are used.

L'utilisation de ces systèmes en milieux agressifs (chimiques ou mécaniques) entraine des usures au niveau des articulations et impliquent donc des opérations de régtages et remplacements périodiques pour compenser les dites usures. The use of these systems in aggressive media (chemical or mechanical) causes wear on the joints and therefore involves periodic adjustment and replacement operations to compensate for said wear.

Le dispositif selon l'invention permet de supprimer ces inconvénients tout en présentant une plus grande simplicité de réalisation et de montage. The device according to the invention makes it possible to eliminate these drawbacks while presenting greater simplicity of construction and assembly.

Le transporteur selon l'invention est constitué d'un chassis mobile animé d'un mouvement cyclique de va et vient au travers d'un organe moteur. Selon la figure 1 ci-aprés, le transporteur est normalement prévu pour un trajet rectiligne horizontal; il pourra etre prévu pour des trajets différents selon des variantes décrites ci-aprés. The conveyor according to the invention consists of a movable chassis animated by a cyclic movement back and forth through a motor member. According to Figure 1 below, the conveyor is normally provided for a horizontal straight path; it may be provided for different routes according to variants described below.

Dans le cas de la figure 1 le mouvement rectiligne alternatif est obtenu au travers de l'action d'un vérin (1) alimenté pour fonctionner alternativement dans un sens ou dans l'autre. In the case of Figure 1 the reciprocating rectilinear movement is obtained through the action of a jack (1) supplied to operate alternately in one direction or the other.

L'ensemble du chassis mobile (2) est supporté et guidé par des glissières solidaires du chassis (2) et galets (8) solidaires du couloir fixe (3). On verra dans la description des variantes ci-aprés que le systéme de guidage peut être différent. The entire movable chassis (2) is supported and guided by slides integral with the chassis (2) and rollers (8) integral with the fixed corridor (3). It will be seen in the description of the variants below that the guidance system may be different.

Sur le chassis (2) sont disposées des supports - entretoises (6) rendues solidaires de celui-ci. Le systéme combiné peigne rigide (4) et lame flexible (5) est rendu solidaire du support entretoise (6) par l'intermédiaire des fixations (7). Les dites fixations n'intéressent que la partie supérieure de la lame flexible. On the chassis (2) are arranged supports - spacers (6) made integral with the latter. The combined rigid comb (4) and flexible blade (5) system is made integral with the spacer support (6) by means of the fasteners (7). Said fasteners only concern the upper part of the flexible blade.

Selon figure 1, l'extrémité de la lame flexible (5) se place naturellement au contact du fond du couloir fixe (3) lorsqu'il n'y a pas présence de matière sur le dit fond. According to Figure 1, the end of the flexible blade (5) is placed naturally in contact with the bottom of the fixed passage (3) when there is no presence of material on said bottom.

Selon figure 2, l'extrémité des dents du peigne (4) est prévue nettement dégagée du fond du couloir (5) de façon à permettre un fonctionnement sans risque de blocage sur un fond de couloir qui ne présenterait pas une surface parfaitement plane.  According to Figure 2, the end of the teeth of the comb (4) is provided clearly disengaged from the bottom of the corridor (5) so as to allow operation without risk of blocking on a bottom of the corridor which would not have a perfectly flat surface.

L'espace entre les dents du peigne est prévu trés supérieur à 'l'épaisseur des dites dents afin d'éviter l'entrainement de matière lors du mouvement retour. The space between the teeth of the comb is provided very much greater than the thickness of said teeth in order to avoid the entrainment of material during the return movement.

Selon figure 3 :
- selon disposition (9) durant le mouvement retour la lame (5) fléchit et se soulève sur la matière. Ce déplacement résulte de l'effet combiné de l'inertie de la matière et de la flexibilité de la lame (5). Les dents du peigne rigide (4) pénétrent dans la matière sans engendrer un déplacement notable.According to figure 3:
- according to arrangement (9) during the return movement the blade (5) flexes and lifts up on the material. This displacement results from the combined effect of the inertia of the material and the flexibility of the blade (5). The teeth of the rigid comb (4) penetrate the material without causing a noticeable displacement.

- selon disposition (10) lors du mouvement aller, l'extrémité de la lame (5) pénétre progressivement dans la matière par l'effet combiné de ressort de lame (5) et de l'inertie de la matière. - According to arrangement (10) during the forward movement, the end of the blade (5) gradually penetrates into the material by the combined effect of leaf spring (5) and the inertia of the material.

- selon disposition (11) la lame (5) s'est déplacée progressivement jusqu'à venir prendre appui sur les dents du peigne (4). Les appuis des dent du peigne (4) sur la lame (5) lui conférent une rigidité suffisante pour vaincre l'inertie de la matière et déplacer cette dernière dans le sens du transport. - According to arrangement (11) the blade (5) has moved gradually until it comes to bear on the teeth of the comb (4). The support of the comb teeth (4) on the blade (5) gives it sufficient rigidity to overcome the inertia of the material and move the latter in the direction of transport.

- selon disposition (12) la matière est évacuée du couloir (3) à son extrémité. - according to arrangement (12) the material is evacuated from the corridor (3) at its end.

Le dispositif selon description est susceptible de se prêter à de nombreuses variantes. The device according to description is likely to lend itself to numerous variants.

Le supportage et le guidage du chassis mobile peuvent être assurés par roulement (galets et glissières) ou par glissement (patins et glissières). The support and guidance of the mobile chassis can be ensured by rolling (rollers and slides) or by sliding (pads and slides).

Le trajet du chassis mobile décrit comme rectiligne horizontal peut être prévu courbe et/ou incliné (ascendant ou descendant). The path of the mobile chassis described as horizontal rectilinear can be provided curved and / or inclined (ascending or descending).

Le mouvement du chassis peut être actionné par vérin pneumatique, hydraulique ou électrique (rectitigne ou rotatif), par systéme biellemanivelle ou par tout autre élément moteur compatible avec le trajet désiré. The movement of the chassis can be actuated by pneumatic, hydraulic or electric actuator (straight or rotary), by a rod-crank system or by any other motor element compatible with the desired path.

Le montage des lames flexibles et des peignes peut être réalisé de l'un oul'autre côté du support entretoise de sorte que l'avancement de la matière peut s'effectuer vers l'une ou l'autre extrémité (ou les deux à la fois) du transporteur, ou même converger on un ou plusieurs points intermédiaires. The flexible blades and the combs can be mounted on one or the other side of the spacer support so that the advancement of the material can take place towards one or the other end (or both at the times) of the transporter, or even converge on one or more intermediate points.

Toutes ces variantes ainsi que celles obtenues par substitution d'éléments techniquement équivalents dans la description ci-dessus rentrent dans le cadre de l'invention.  All of these variants, as well as those obtained by substitution of technically equivalent elements in the description above, fall within the scope of the invention.
