Abstract
Description
L'invention a pour objet un dispositif pour mesurer et contrôler la tension d'une courroie utilisant une déformation constante avec mesure de la force exercée sur un moyen faisant office de jauge de contrainte.The invention relates to a device for measuring and controlling the tension of a belt using constant deformation with measurement of the force exerted on a means acting as a strain gauge.
Ledit dispositif est indépendant de l'épaisseur de la courroie à mesurer et/ou à contrer. Said device is independent of the thickness of the belt to be measured and / or countered.
L'état de la technique peut être défini par les brevets suivants - Demande de Brevet d'invention déposée le 26 juin 1987 sous le n 87 09110 par la Société SUD-EST ELECTRO-MECANIQUE S.E.E.M. Le dispositif est composé d'un châssis boîtier sur lequel est montée une presse qui applique une déformation constante sur le support de la jauge de contrainte, ledit support est monte pivotant sur un axe et est en contact, d'une part, avec la presse et, d'autre part, avec une face de la courroie, ladite courroie à mesurer étant maintenue dans un triangle, entre le point de contact avec le support de ladite jauge sur une face et deux galets sur l'autre face, ladite jauge de contrainte est reliée électriquement à un microprocesseur. The state of the art can be defined by the following patents - Patent application filed June 26, 1987 under number 87 09 110 by the company SUD-EST ELECTRO-MECANIQUE S.E.E.M. The device is composed of a box chassis on which is mounted a press which applies a constant deformation on the support of the strain gauge, said support is mounted to pivot on an axis and is in contact, on the one hand, with the press and, on the other hand, with one side of the belt, said belt to be measured being held in a triangle, between the point of contact with the support of said gauge on one side and two rollers on the other side, said gauge constraint is electrically connected to a microprocessor.
On peut noter également le brevet US.A.3.653.258 (H.KING). We can also note the patent US.A.3.653.258 (H.KING).
Ces dispositifs présentent un inconvénient majeur. La mesure ou le contrôle de la tension s'effectue par trois points de contact, deux galets et le moyen de la mécanisation de la contrainte. Les deux galets se trouvent sur une face de la courroie et la jauge de contrainte sur l'-autre face. These devices have a major drawback. The measurement or the control of the tension is carried out by three points of contact, two rollers and by the means of the mechanization of the stress. The two rollers are on one side of the belt and the strain gauge on the other side.
Les dispositifs impliquent une grande précision dans l'étalonnage. The devices imply great accuracy in calibration.
Pour chaque type de courroie, le fabricant du dispositif indique l'action à exercer sur la vis qui fait office de presse. Selon la fiche technique du constructeur du dispositif, ladite courroie doit être tendue à un indice donné que l'utilisateur règle au niveau de la courroie après avoir mesuré ladite tension. For each type of belt, the manufacturer of the device indicates the action to be exerted on the screw which acts as a press. According to the technical sheet of the manufacturer of the device, said belt must be tensioned to a given index that the user adjusts at the level of the belt after having measured said tension.
En fait, pour un menue type de courroie, les caractéristiques techniques de fabrication varient légèrement, notamment au niveau de l'épaisseur de la courroie. In fact, for a small type of belt, the technical characteristics of manufacturing vary slightly, especially in terms of the thickness of the belt.
Ainsi, par exemple, pour une courroie d'un meme type et d'une épaisseur de - dl=7,2 mm : la différence peut etre de +0,3 mm - d2=7,5 mm . la différence peut être de +0,3 ;zz.. tm
+0,5 mm - d3=8 mn. la différence peut être de +0,2 mn
Du fait de la disposition des trois points de contact, l'importance de l'épaisseur de la courroie à mesurer est considérable. Thus, for example, for a belt of the same type and with a thickness of - dl = 7.2 mm: the difference may be +0.3 mm - d2 = 7.5 mm. the difference can be +0.3; zz .. tm
+0.5 mm - d3 = 8 min. the difference can be +0.2 min
Due to the arrangement of the three contact points, the importance of the thickness of the belt to be measured is considerable.
L'invention tend à éviter tous ces inconvénients. The invention tends to avoid all these drawbacks.
Elle permet d'appliquer une déformation constante pour chaque type de courroie et de mesurer et/ou de contrôler la tension de ladite courroie et ce, indépendamment des variations d'épaisseur dues à la fabrication pour un même type de courroie. It makes it possible to apply a constant deformation for each type of belt and to measure and / or control the tension of said belt, regardless of variations in thickness due to manufacturing for the same type of belt.
A cet effet, le dispositif, selon l'invention, utilise un châssis boîtier sur lequel on obtient une déformation constante avec mesure de la force exercée sur une jauge de contrainte ; le point de contact de la mécanisation de la jauge de contrainte est disposé sur la même face de la courroie que deux galets ou références fixes ; le point de contact de la mécanisation de la jauge de contrainte est disposé entre les deux galets. To this end, the device according to the invention uses a box chassis on which a constant deformation is obtained with measurement of the force exerted on a strain gauge; the point of contact of the mechanization of the strain gauge is arranged on the same face of the belt as two rollers or fixed references; the point of contact for the mechanization of the strain gauge is disposed between the two rollers.
Sur l'autre face de la courroie, deux doigts presseurs viennent en regard des deux galets. Lesdits doigts presseurs peuvent etre animés par une presse hydro pneumatique.On the other side of the belt, two pressing fingers come opposite the two rollers. Said pressing fingers can be animated by a hydro pneumatic press.
Ladite jauge de contrainte est reliée électriquement à un microprocesseur intégré dans le boîtier. Un ensemble de diodes luminescentes permet de visualiser le niveau de tension de la courroie. Said strain gauge is electrically connected to a microprocessor integrated in the housing. A set of light-emitting diodes makes it possible to visualize the tension level of the belt.
Une prise électrique permet de relier l'ensemble de ce boîtier à d'autres appareil s de cominande et/ou de mesure.An electrical outlet makes it possible to connect the whole of this box to other control and / or measurement devices.
