DISPOSITIF POUR MESURER L'EPAISSEUR SOUS DIFFERENTES
CHARGES D'UN MATERIAU EN PLAQUE, TEL QU'UN CARTON ONDULE.DEVICE FOR MEASURING THICKNESS UNDER DIFFERENT
LOADS OF PLATE MATERIAL, SUCH AS A CORRUGATED BOX.
L'invention concerne un dispositif pour mesurer l'épaisseur sous différentes charges d'un matériau en plaque, compressible notamment, tel que du carton ondulé, spécialement au milieu de ces plaques. The invention relates to a device for measuring the thickness under different loads of a plate material, compressible in particular, such as corrugated cardboard, especially in the middle of these plates.
I1 est bien connu de mesurer sous différentes charges l'épaisseur d'un matériau en plaque. Bien que dans la suite de la description, on fasse essentiellement référence à un matériau compressible et plus précisément à du carton ondulé, l'invention n'est nullement limitée à ce type de produit. It is well known to measure the thickness of a plate material under different loads. Although in the following description, reference is essentially made to a compressible material and more precisely to corrugated cardboard, the invention is in no way limited to this type of product.
Dans le domaine des cartons ondulés, on sait qu'il existe une corrélation entre les pertes d'épaisseur sous différentes charges prédéterminées et la perte de résistance à la compression verticale de ce carton causée par les écrasements à plat subis lors de sa fabrication et de sa transformation en caisse. In the field of corrugated cardboard, it is known that there is a correlation between the losses of thickness under different predetermined loads and the loss of resistance to vertical compression of this cardboard caused by the flat crushing undergone during its manufacture and its transformation into a cash register.
A ce jour, on mesure cette épaisseur à l'aide d'un appareil constitué d'une mâchoire en forme de U associée à un organe de lecture de l'enfoncement des mâchoires dans une éprouvette de ce carton, lesdites mâchoires recevant des charges prédéterminées. Bien que cet appareil soit largement répandu, il ne permet pas, du fait de la- faible profondeur du U (dix à quinze centimètres), de réaliser des mesures au milieu des plaques sans les rendre inutilisables. To date, this thickness is measured using an apparatus consisting of a U-shaped jaw associated with a member for reading the insertion of the jaws into a test piece of this carton, said jaws receiving predetermined loads. . Although this device is widely used, it does not, because of the shallow depth of the U (ten to fifteen centimeters), make measurements in the middle of the plates without making them unusable.
L'invention pallie ces inconvénients. Elle concerne un dispositif du type en question qui soit léger, facile à construire et -à manipuler, qui permette la mesure au milieu des plaques, même de grandes dimensions,sans les découper, donne des résultats fiables, et puisse être utilisé aussi bien en laboratoire que dans une atmosphère chaude et humide, comme on en rencontre souvent dans les ateliers. The invention overcomes these drawbacks. It relates to a device of the type in question which is light, easy to construct and to handle, which allows measurement in the middle of the plates, even of large dimensions, without cutting them, gives reliable results, and can be used both laboratory than in a hot and humid atmosphere, as we often find in workshops.
Ce dispositif pour mesurer l'épaisseur sous différentes charges d'un matériau en plaque, tel qu'un carton ondulé, constitué par
un ensemble destine à venir enserrer lléprou-
vette, formé de deux plaques paralleles, l'une
fixe, l'autre mobile, la plaque mobile étant
apte à recevoir des charges prédéterminées,
un organe de lecture destiné à mesurer l'en
foncement de la plaque mobile dans l'éprou
vette sous l'effet de charges prédéterminées, se caractérise :
- en ce que la plaque fixe comporte une aiguille dépassante
- et en ce que l'organe de lecture comporte des moyens aptes à déterminer la longueur de ladite aiguille qui dépasse de l'éprouvette comprimée par la plaque mobile chargée.This device for measuring the thickness under different loads of a plate material, such as corrugated cardboard, consisting of
a set intended to come and grip the test
vette, formed of two parallel plates, one
fixed, the other mobile, the mobile plate being
able to receive predetermined loads,
a reading device intended to measure the
darkening of the moving plate in the test piece
vette under the effect of predetermined loads, is characterized:
- in that the fixed plate has a protruding needle
- And in that the reading member comprises means capable of determining the length of said needle which protrudes from the test piece compressed by the loaded movable plate.
En d'autres termes, l'invention consiste à mesurer le dépassement à travers l'éprouvette d'une aiguille solidaire de la plaque fixe lorsque des charges prédéterminées sont appliquées sur la plaque mobile. In other words, the invention consists in measuring the protrusion through the test piece of a needle secured to the fixed plate when predetermined loads are applied to the movable plate.
Avantageusement, en pratique
- la longueur de dépassement à vide de l'aiguille est réglable en hauteur
- la plaque mobile est fixée à l'extrémité d'un bras articulé qui porte une charge prédéterminée et dont l'autre extrémité est articulée sur un bâti autour d'un axe disposé dans le plan horizontal de la plaque fixe
- ce bras chargé est retenu par un premeir levier fixé sur un montant solidaire du bâti
- ledit montant présente un second bras articulé sur ce montant, portant une deuxième charge prédéterminée, retenue par un deuxième levier fixé sur ce montant, ledit deuxième bras libéré venant s'appuyer sur le premier bras également libére
- le deuxième bras chargé est parallèle au montant et est libéré par le déplacement d'un second levier articulé sur ledit montant, ce second levier étant solidaire d'une câmessqui à son tour est solidaire d'un troisième bras articulé sur le deuxième bras, qui à son tour, sous 11 effet de l'action du deuxième levier, vient prendre appui sur le premier bras libéré
- les plaques sont circulaires et concentriques;
- le bâti a la forme d'un U couché dont le montant forme l'une des branches ;
- l'organe de lecture est un comparateur.Advantageously, in practice
- the protruding length of the needle when empty is adjustable in height
- the movable plate is fixed to the end of an articulated arm which carries a predetermined load and the other end of which is articulated on a frame around an axis disposed in the horizontal plane of the fixed plate
- this loaded arm is retained by a first lever fixed on an upright secured to the frame
- Said upright has a second arm articulated on this upright, carrying a second predetermined load, retained by a second lever fixed on this upright, said second released arm coming to bear on the first arm also released
the second loaded arm is parallel to the upright and is released by the displacement of a second lever articulated on said upright, this second lever being secured to a cam which in turn is secured to a third arm articulated on the second arm, which in turn, under the effect of the action of the second lever, comes to rest on the first released arm
- the plates are circular and concentric;
- the frame has the shape of a lying U whose amount forms one of the branches;
- the reading device is a comparator.

La figure 2 est une vue également en coupe de ce même dispositif,en action partielle. Figure 2 is a sectional view of the same device, in partial action.
La figure 3 est une vue de ce même dispositif, montré lorsque toutes les charges sont appliquées. Figure 3 is a view of this same device, shown when all the loads are applied.
Enfin la figure 4 est une vue de face de l'organe ne de lecture comparateur. Finally Figure 4 is a front view of the comparator reading member.
Le dispositif de mesure selon l'invention se composte essentiellement d'un bâti (1) en forme de U couché comprenant deux branches parallèles (2) et (3) formant montants. A l'extrémité du montant inférieur (3), on fixeune plaque circulaire (4) de surfacetarée . Au centre decette plaque, débouche une fine aiguille en acier (5),solidaire d'une vis (6) de réglage en hauteur, actionnable par-dessous le montant inférieur (3). Ainsi, on peut régler à des hauteurs variables la lonqueur prédéterminée de l'aiguille (5) qui dépasse ainsi de la plaque fixe (4) pour traverser l'éprouvette. The measuring device according to the invention essentially consists of a frame (1) in the shape of a coated U comprising two parallel branches (2) and (3) forming uprights. At the end of the lower upright (3), a circular surface plate (4) is fixed. In the center of this plate, a fine steel needle (5) opens, secured to a height adjustment screw (6), operable from below the lower upright (3). Thus, the predetermined length of the needle (5) can be adjusted at variable heights, which thus protrudes from the fixed plate (4) to pass through the test piece.
Un bras (6) articulé à une extrémité en (7) sur le bâti (1) autour de cet axe (7) disposé sensiblement dans le même plan horizontal que celui de la plaque fixe (4), porte à son autre extrémité une plaque mobile circulaire (8),également tarée,dont la surface correspond sensiblement à celle de la plaque fixe (4). Cette plaque mobile (8) est, lorsqu'elle vient en appui sur (4),concentrique à (4). Elle présente en son centre un orifice (9) dans lequel peut pénétrer l'aiguille (5). An arm (6) articulated at one end at (7) on the frame (1) around this axis (7) disposed substantially in the same horizontal plane as that of the fixed plate (4), carries at its other end a plate circular mobile (8), also tared, the surface of which corresponds substantially to that of the fixed plate (4). This movable plate (8) is, when it comes to bear on (4), concentric with (4). It has in its center an orifice (9) into which the needle (5) can penetrate.
Cette plaque mobile (8) est disposée à l'extrémité (10) du bras (6) unposé à l'axe d'articulation (7). Le bras (6) qui
Dorte en outre une charqe prédéterminée (11) présente, dans la portion comprise entre l'extrémité (10) et la plaque mobile (8), un comparateur (12) montré à la figure 4. Ce comparateur (12) est essentiellement constitué par une aiquille (13) qui, par des renvois classiques et appropriés,commande deux aiquilles de lecture (30) et (31) du comparateur (12).This movable plate (8) is disposed at the end (10) of the arm (6) which is placed on the hinge pin (7). The arm (6) which
Also carries a predetermined frame (11) present, in the portion between the end (10) and the movable plate (8), a comparator (12) shown in Figure 4. This comparator (12) consists essentially of a needle (13) which, by conventional and appropriate references, controls two reading needles (30) and (31) of the comparator (12).
L'aiguille mobile (13)'poussée Dar l'aiguille fixe (5) entraîne les aiguilles de lecture (30,31).The movable needle (13) 'pushed Dar the fixed needle (5) drives the reading needles (30,31).
Un premier levier (14) est articulé en (15) sur le montant supérieur (2). Ce levier (14) est associé à une biellette (16) qui par une tringle (17) qui est reliée à l'extrémité (10) du bras (6). A first lever (14) is articulated at (15) on the upper upright (2). This lever (14) is associated with a link (16) which by a rod (17) which is connected to the end (10) of the arm (6).
La référence (18) désigne l'éprouvette à mesurer par exemple de carton ondulé. On place cette éprouvette (18) sur la plaque fixe (4). L'aiguille (5) traverse cette éprouvette (18) d'une longueur prédéterminée correspondant au zéro du comparateur. On bascule ensuite le levier (14) comme indiqué à la figure 2. Ce mouvement de pivotement autour de l'axe (15) détend la tringle de retenue (17), ce qui sous l'effet de la charge (11) amene le bras (6) et plus précisément la plaque mobile (8) au contact de l'éprouvette (18). Sous lteffet de la pression exercée par cette première charge prédéterminée (11), la plaque mobile (8) s'enfonce d'une hauteur déterminable dans l'éprouvette (18). Ainsi, l'aiguille mobile (13) vient s'appuyer sur l'aiguille fixe (5) qui entraîne celles (30,31) du comparateur (12). Cela donne une première lecture. The reference (18) designates the test piece to be measured, for example of corrugated cardboard. This test piece (18) is placed on the fixed plate (4). The needle (5) passes through this test piece (18) of a predetermined length corresponding to the zero of the comparator. We then rock the lever (14) as shown in Figure 2. This pivoting movement around the axis (15) relaxes the retaining rod (17), which under the effect of the load (11) brings the arm (6) and more precisely the movable plate (8) in contact with the test piece (18). Under the effect of the pressure exerted by this first predetermined load (11), the movable plate (8) sinks a determinable height into the test piece (18). Thus, the movable needle (13) comes to bear on the fixed needle (5) which drives those (30,31) of the comparator (12). This gives a first reading.
Le dispositif comporte un second bras (19) articulé en (20) sur le montant supérieur (2) (figure 3). L'extrémité opposée à l'axe d'articulation (20) de ce bras (19) comporte des charges prédéterminées (21,22). Un levier (23) est articulé en (24) sur le montant supérieur (2). Ce levier est associé à unr câble (25), qui à son tour est solidaire d'un troisième bras (26) articulé en (27) sur le deuxième bras (19). Lorsque le levier (23) (voir figure 3) pivote dans le sens indiqué par la flèche à la figure 1 autour de l'axe (24), la câme (25) détend dans un premier temps le câble (28), ce qui entraîne le pivotement du bras (26). Ce bras (26) en pivotant vient alors se placer verticaiement au-dessus d'un méplat (32) prévu à cet effet à l'extrémité du bras (6). Puis, dans un deuxième temps, la câme (25) libère le bras (19).Ainsi, le bras (19) vient prendre appui par l'intermédiaire du bras (26) sur le premier bras (6), ce qui additionne les charges (21,22), amplifiées par l'effet de levier, à la charge (11), de sorte que l'ensemble est ainsi appliqué par la plaque mobile (8) sur l'échantillon (18) à mesurer. On obtient ainsi une deuxième mesure, sous une deuxième charge prédéterminée. The device comprises a second arm (19) articulated at (20) on the upper upright (2) (Figure 3). The end opposite the articulation axis (20) of this arm (19) has predetermined loads (21,22). A lever (23) is articulated at (24) on the upper upright (2). This lever is associated with a cable (25), which in turn is integral with a third arm (26) articulated at (27) on the second arm (19). When the lever (23) (see Figure 3) pivots in the direction indicated by the arrow in Figure 1 around the axis (24), the cable (25) initially relaxes the cable (28), which causes the arm (26) to pivot. This pivoting arm (26) is then placed vertically above a flat (32) provided for this purpose at the end of the arm (6). Then, in a second step, the cam (25) releases the arm (19). Thus, the arm (19) comes to bear via the arm (26) on the first arm (6), which adds the loads (21,22), amplified by the leverage, to the load (11), so that the assembly is thus applied by the movable plate (8) to the sample (18) to be measured. A second measurement is thus obtained, under a second predetermined load.
La comparaison entre la première mesure (figure 2) et la seconde mesure (figure 3) donne une indication de la résistance à la compression verticale. The comparison between the first measurement (Figure 2) and the second measurement (Figure 3) gives an indication of the resistance to vertical compression.

Le dispositif selon l'invention présente de nombreux avantages par rapport aux dispositifs analogues utilisés à ce jour. On peut citer
- sa simplicité de construction et de fonctionnement, même par du personnel non spécialisé
- sa légèreté, ce qui permet de le transporter facilement d'un point à un autre et même à proximité d'une machine
- le fait que l'échantillon (18) mesuré n'est pas détérioré ou détruit, si ce n'est le petit trou provoqué par l'aiguille ;
- sa fiabilité
- la possibilité d'être utilise aussi bien en laboratoire que dans des atmosphères chaudes et humides, telles que l'on en rencontre dans les ateliers

Ce dispositif peut donc être utilisé avec succès pour mesurer l'épaisseur sous différentes charges des cartons ondulés de toutes sortes, tels que par exemple double face, double double, etc.. Il peut être également utilisé avec d'autres matériaux facilement compressibles et transperçables, tels que par exemple des plaques de matière plastique en forme de mousse, des feutres, du cuir. This device can therefore be successfully used to measure the thickness under different loads of corrugated cardboard of all kinds, such as for example double-sided, double double, etc. It can also be used with other easily compressible and pierceable materials , such as for example plastic plates in the form of foam, felts, leather.
