Abstract

The belt comprises a mechanical assembly constituted by a metal strip of very precise length, welded at its ends so as to form an endless belt. On the inside of one of the edges reference marks are cut or printed so as to constitute a length measurement indicator. The outside of the belt is coated with a nonskid layer. The inner part of a protection layer comprising two longitudinal guiding projections. The device according to the invention is in particular intended for the construction of an apparatus for measuring cables or long products, ribbons, plates, etc. The applications relate to the navy or merchant marine, petrochemical research, industrial fishing, the cable industry, the preparation of rollers and spools (coils), oceanography, etc.

Description

La présente invention concerne la mesure de précision de la longueur des câbles et de tous produits linéaires souples ou rigides en cours de défilement. The present invention relates to the precision measurement of the length of cables and of all flexible or rigid linear products during scrolling.

Dans les dispositifs connus soit à t8tes magnétiques, soit par enroulement, ou,semi-enroulement mécanique sur les poulies il existe une imprécision. Les produits à têtes magnétiques ne peuvent mesurer que des produits aimantables, ce qui exclue les cables synthétiques, nylons, Kevlar etc..les bois , les plastics
D'autre part à la suite d'un défilement très lent les systèmes à têtes magnétiques présentent un défaut s le signal est impossible à différencier du bruit de fond, toute mesure devient aléatoire.Dans les dispositifs mécaniques le report de deux circonférences superposées ne tient aucun compte de la valeur moyenne, mais seulement d'une longueur periphérique variable, par suite de la contrainte du produit mesuré dans sa masse.In known devices either with magnetic heads, or by winding, or, mechanical semi-winding on the pulleys, there is an imprecision. Products with magnetic heads can only measure magnetizable products, which excludes synthetic cables, nylons, Kevlar, etc., wood, plastics
On the other hand, following a very slow scrolling, the systems with magnetic heads have a defect s the signal is impossible to differentiate from the background noise, any measurement becomes random. In mechanical devices the transfer of two superimposed circumferences does not hold no account of the average value, but only of a variable peripheral length, due to the constraint of the product measured in its mass.

Même une courroie travaillant en inversion de sens, est soumise à la m8me Loi du report de circonférences. Even a belt working in reverse direction, is subject to the same Law of the transfer of circumferences.

Afin de s'affranchir de tous ces défauts il convient que la mesure s'effectue par la comparaison de deux lignes droites; le comptage s'opérant sur l'une des deux parties parfaitement symétrique à l'autre, aucune erreur n'est possible. In order to overcome all these faults, the measurement should be made by comparing two straight lines; since the counting takes place on one of the two parts perfectly symmetrical to the other, no error is possible.

Le dispositif obJet de l'invention se compose d'une courroie spéciale à texture metallique, sous forme d'un feuillard de longueur très précise. La partie superficielle de cette courroie est formée d'un caoutchouc rugueux anti-dérapant chargé d'assurer une parfaite adhérence avec le produit à mesurer: câbles, plaques,rubans, de quelques natures qu'ils soient. La partie interne de la courroie est revalue d'une couche de protection, soit caoutchouc, ou synthétique ou n'importe quel autre produit avec guidages latéraux. Cette partie du revêtement laisse une marge apparente sur un cBté de la courroie. Dans cette marge la partie comptage du feuillard formant la texture est laissée à nu. The object device of the invention consists of a special belt with metallic texture, in the form of a strip of very precise length. The surface part of this belt is formed of a rough non-slip rubber responsible for ensuring perfect adhesion with the product to be measured: cables, plates, tapes, whatever their nature. The internal part of the belt is revalued with a protective layer, either rubber, synthetic or any other product with lateral guides. This part of the coating leaves an apparent margin on one side of the belt. In this margin the counting part of the strip forming the texture is left bare.

Par un dispositif électronique à cellules infra-rouge placé face à la partie interne de la courroie, s'opère le comptage de la longueur défilée. Cette mê partie électronique assure le choix du'sens et assure le comptage ou dcompage suivant le cas. Saule demeure affichée la longueur exacte quels,que que soient le nombre et le sens des manoeuvres. By means of an electronic device with infrared cells placed opposite the internal part of the belt, the running length is counted. This same electronic part ensures the choice of the direction and ensures the counting or decompression according to the case. Willow remains displayed the exact length whatever the number and the direction of the maneuvers.

Grâce à cette courroie spéciale la longueur de défilement du produit à mesurer sera rigoureusement identique à la longueur de courroie ayant accompagné le produit dans son déplacement. Thanks to this special belt, the running length of the product to be measured will be exactly the same as the length of the belt that accompanied the product in its movement.

Le dessin Fig 1 illustre la composition de la courroie obJet de la présente invention. The drawing Fig 1 illustrates the composition of the object belt of the present invention.

Le dessin Fig 2 illustre à titre d'exemple non limitatif la construction d'un appareil équipé de cette courroie comparateur de mesure. L'appareil comprend un ensemble mécanique (1) supportant deux galets(2-2") montés sur des axes (33n) tounnant en rotation parfaitement libre. Sur les galets ( 2-2") circule une courroie spéciale obJet de la présente invention (4) à texture composée d'un feuillard compnr- tant les indications de mesure découpéesiou imprimées.Un dispositif lectronique (7) comportant deux détecteurs infrarouge (8-9) comptent le nombre de repères correspondant à une longueur pré-établie. Le dispositif électronique (7) tratte les signaux, détecte le sens du défilement, afin d' assurer la fonction comptage ou comptage suivant le cas et converti le résultat en chiffres que l'on peut lire sur untableau soit Joint soit sépare. The drawing Fig 2 illustrates by way of nonlimiting example the construction of a device equipped with this measuring comparator belt. The device comprises a mechanical assembly (1) supporting two rollers (2-2 ") mounted on axes (33n) rotating in perfectly free rotation. On the rollers (2-2") circulates a special belt object of the present invention (4) with a texture composed of a strip comprising the cut or printed measurement indications. An electronic device (7) comprising two infrared detectors (8-9) count the number of marks corresponding to a preset length. The electronic device (7) picks up the signals, detects the direction of travel, in order to perform the counting function or counting depending on the case and converts the result into figures which can be read on a table either joined or separated.

L'invention peut être utilisée en océanographle, pêche industrielle, recherche pétrolière, production ou débit des câbles ou produits de grande longueur. L'invention peut également être utilisée pour commander toutes sortes de manoeuvres liées à la mesure de longueur, telles que s tron çonnage, cisaillage,- confection de rouleaux et bobines etc. The invention can be used in oceanography, industrial fishing, petroleum research, production or flow of cables or products of great length. The invention can also be used to control all kinds of maneuvers related to length measurement, such as cutting, shearing, - making rolls and coils, etc.
