Abstract

The table supports and guides a piece to be worked on (11) upstream or downstream of a production machine comprising a frame (16), a movable table (12) and rise/fall axles (15). A table support (1) can move vertically and assures a constant force on the movable table (12) via a flexible element (6) fixed on the opposite side of the table (12). Rollers (4, 17, 14) preferably assure the transmission of movement and the force between the tables (1, 12) via flexible element (6). A case (7) allows the adjustment of tension of the flexible element (6). USE/ADVANTAGE - Industrial production machines of which the work-table is movable vertically.

Description

TABLE SUIVE#USE
La présente invention concerne un dispositif destiné à guider et supporter une pièce à usiner en amont ou en aval d'une machine de production dont la table est mobile verticalement.FOLLOWING TABLE # USE
The present invention relates to a device intended to guide and support a workpiece upstream or downstream of a production machine whose table is vertically movable.

Les machines de type raboteuses ? ponceuses... ont des tables de travail mobiles verticalement.La position des pièces travaillées n est pas toujours centrée par rapport à la machine de production et dépasse souvent les extrémités de celle-ci,ce qui nécessite dans ce cas un soutien en amont ou en aval d'une ou plusieurs personnes.Ce soutien est généralement assisté par une table mobile verticalement réglée par l'opérateur visuellement,donc de manière peu précise. Planer type machines? sanders ... have vertically movable work tables. The position of the workpieces is not always centered relative to the production machine and often exceeds the ends of the machine, which in this case requires support upstream or downstream of one or more people. This support is generally assisted by a movable table vertically adjusted by the operator visually, therefore with little precision.

Le réglage ou le soutien est quelquefois solutionné par une table mobile mue par des vérins ou des moteurs et commandée par la machine de production. Adjustment or support is sometimes solved by a mobile table driven by jacks or motors and controlled by the production machine.

Le problème est que mème dans ce cas l'effort dû au poids de la pièce à travailler n'est pas constant sur chaque axe de montée/descente de la table mobile de la machine de production et peut occasionner une inclinaison de cette table due aux jeux de fonctionnement dans les axes lorsque la pièce à travailler est en position extrème.Ceci produit des usinages irréguliers sur la pièce. The problem is that even in this case the force due to the weight of the workpiece is not constant on each axis of ascent / descent of the movable table of the production machine and can cause an inclination of this table due to operating clearances in the axes when the workpiece is in the extreme position. This produces irregular machining on the workpiece.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

Il comporte une table mobile{1) sur laquelle sont fixées une ou plusieures tiges(3) solidaires de l'élément souple(6) par l'intermédiaire du boitier de réglage(7) et de la traverse(8).Tous ces éléments sont mobiles verticalement grâce au colones de guidage(9) solidaires d'un socle fixe(10).  It comprises a movable table {1) on which are fixed one or more rods (3) integral with the flexible element (6) by means of the adjustment box (7) and of the cross-member (8). are movable vertically thanks to the guide columns (9) secured to a fixed base (10).

L'élément souple(6) est relié à la la machine de production composée d'un bati(1t),d'axes de montée/descente(15) et d'une table mobile(19) par l'intermédiaire de la chape(13).  The flexible element (6) is connected to the production machine composed of a frame (1t), up / down axes (15) and a movable table (19) via the yoke (13).

La transmission du mouvement de la table(1^) à la table (il) et des efforts dûs au poids de la pièce(11) est assurée par l'élément souple(6) et les paliers(4$17?14)
Le palier(4) est fixé sur une barre(5) solidaire des colones de guidage(9). The transmission of the movement from the table (1 ^) to the table (it) and of the forces due to the weight of the part (11) is ensured by the flexible element (6) and the bearings (4 $ 17? 14)
The bearing (4) is fixed to a bar (5) integral with the guide columns (9).

Le boitier (7) permet d'assurer la tension et le réglage de l'élément souple(5).  The housing (7) ensures the tension and the adjustment of the flexible element (5).

Le plateau(2) assure la continuité du plan formé par la table mobile(12) de la machine de production et par la table(1). The plate (2) ensures the continuity of the plane formed by the movable table (12) of the production machine and by the table (1).

Le plateau(2) est composé d'un système d'entrainement type galet,rouleaux,tapis(non représenté) permettant le transfert de la pièce(11) latéralement ou en bout de ce plateau(2). The plate (2) is composed of a drive system such as a roller, rollers, carpet (not shown) allowing the transfer of the part (11) laterally or at the end of this plate (2).

L'effort exercé par le poids de l'ensemble étudié se répercute de manière constante sur les axes de montée/descente(15) Cela permet de ne pas déséquilibrer la table(l). The force exerted by the weight of the unit studied has a constant effect on the up / down axes (15). This makes it possible not to unbalance the table (l).

Lorsque que le centre de gravité de la pièce à travailler(l#) a dépassé l'axe de la machine de production lteffort dû au poids de cette pièce se répercute de manière sensiblement constante sur les axes de montée/descente(15) et ceci quelque soit la position de la pièce a travailler par rapport à la table(1).  When the center of gravity of the workpiece (l #) has exceeded the axis of the production machine lteffort due to the weight of this part is reflected in a substantially constant manner on the axes of ascent / descent (15) and this whatever the position of the workpiece relative to the table (1).

A titre d'exemple non limitatif,la table(1) plus le plateau(2) auront une longueur de 2.5m et une hauteur réglable de O.5 à lm.  By way of nonlimiting example, the table (1) plus the tray (2) will have a length of 2.5m and an adjustable height from O.5 to lm.

Le dispositif selon l'invention est particulièrement destiné aux machines de production de l'industrie dont la table de travail est mobile en hauteur.  The device according to the invention is particularly intended for industrial production machines whose work table is movable in height.
