Abstract
Description
Appareil à affûter, pour l'affûtage de la lame de coupe sur une machine à tisser le velours double nappe. Sharpening device, for sharpening the cutting blade on a double ply velor weaving machine.
La présente invention concerne un appareil à affûter pour affûter la lame de coupe qui sert à trancher les deux nappes d'un tissu velours chaîne. The present invention relates to a sharpening device for sharpening the cutting blade which is used to slice the two plies of a warp velvet fabric.
Pour le tissage du velours double nappe sur une machine à tisser, la séparation des deux nappes se fait généralement sur la machine elle-meme. For the weaving of double ply velvet on a weaving machine, the separation of the two plies is generally done on the machine itself.
Une lame coupante est montée sur un chariot de coupe qui, lui-même repose sur une glissière ; ledit chariot est animé d'un mouvement de va-et-vient et permet à la lame de trancher les fils poil reliant les deux nappes entre elles. A cutting blade is mounted on a cutting carriage which itself rests on a slide; said carriage is driven back and forth and allows the blade to cut the pile son connecting the two layers together.
Il va de soi qu'une lame affûtée au départ ne peut assurer une coupe parfaite du poil après quelques mètres tissés. It goes without saying that a blade sharpened at the start cannot ensure a perfect cut of the hair after a few meters woven.
Ainsi est associé à la lame de coupe mobile au moins un appareil à affûter, généralement un appareil à droite et un appareil à gauche de la laize, dans le but d'entretenir le fil de la lame toujours en parfait état de coupe, sur les deux faces de la lame. Thus is associated with the mobile cutting blade at least one sharpening device, generally a device on the right and a device on the left of the width, in order to maintain the edge of the blade always in perfect cutting condition, on the two sides of the blade.
Jusqu'à présent, chaque appareil à affûter comprenait comme organe d'affûtage une, et plus généralement, deux pierres à affûter,l'une de ces pierres affûtant la lame de coupe sur le dessus, tandis que la deuxième l'affûte par en dessous. Until now, each sharpening device has comprised as sharpening member one, and more generally, two sharpening stones, one of these stones sharpening the cutting blade on the top, while the second sharpens it by below.
Pour diminuer les chocs et les rebondissements de pierres au contact de la lame qui détériorent le tranchant de la lame, on montait les pierres sur des supports équilibrés formant bascule et on essayait de réduire l'inertie des pierres et de leurs supports. To reduce the shocks and twists of stones in contact with the blade which deteriorate the edge of the blade, the stones were mounted on balanced supports forming a rocker and we tried to reduce the inertia of the stones and their supports.
Cependant, sur les machines modernes à tisser le velours à grande vitesse, par exemple de l'ordre de 250 coups/minute, les appareils d'affûtage classiques à pierres entraînent, malgré les systèmes d'amortissement d'équilibrage, une usure rapide de la lame de coupe, qui est affûtée à grande vitesse, généralement deux fois par cycle de tissage. De plus, l'angle d'attaque de la lame prend une forme dissymétrique difficile à corriger. However, on modern machines for weaving velvet at high speed, for example of the order of 250 strokes / minute, conventional stone sharpening machines cause, despite the balancing damping systems, rapid wear of the cutting blade, which is sharpened at high speed, generally twice per weaving cycle. In addition, the angle of attack of the blade takes on an asymmetrical shape which is difficult to correct.
La présente invention a pour but de remédier à ces inconvénients. The present invention aims to remedy these drawbacks.
L'invention consiste à -utiliser, comme organe d'affûtage de la lame de coupe, non plus une pierre à affûter, mais un tronçon de fusil à affiler, dit "fusil de boucher". The invention consists in using, as a member for sharpening the cutting blade, no longer a sharpening stone, but a section of sharpening steel, said "butcher's rifle".
Suivant une forme préférée de réalisation, on monte deux de ces tronçons, face à face, en orientation croisée, chacun de ces tronçons étant supporté par une lame de ressort. According to a preferred embodiment, two of these sections are mounted, face to face, in cross orientation, each of these sections being supported by a leaf spring.
La demanderesse a pu observer que, grâce à ce système d'affûtage, la lame de coupe a une durée de vie plus longue, sur les machines à tisser à grande vitesse, tout en conservant le tranchant nécessaire. The Applicant has been able to observe that, thanks to this sharpening system, the cutting blade has a longer service life, on weaving machines at high speed, while retaining the necessary cutting edge.
L'invention sera mieux comprise à l'aide de la description et des dessins qui suivent. Sur ces dessins
la figure 1 est une vue en élévation, partiellement en coupe de l'appareil à affûter et de la lame- de coupe,
la figure 2 est une vue en plan du même appareil,
la figure 3 est une vue schématique en perspective montrant la disposition croisée des deux tronçons de fusil de boucher.The invention will be better understood with the aid of the description and the drawings which follow. On these drawings
FIG. 1 is an elevation view, partially in section, of the sharpening apparatus and of the cutting blade,
FIG. 2 is a plan view of the same device,
Figure 3 is a schematic perspective view showing the crossed arrangement of the two sections of butcher's rifle.
Sur la figure 1, on a représenté la lame de coupe 2 d'une machine à tisser le velours double nappe, qui est fixée sur un chariot 4 coulissant sur une glissière transversale 6 solidaire du bâti 8 de la machine, ainsi qu'il est bien connu. In Figure 1, there is shown the cutting blade 2 of a double-ply velvet weaving machine, which is fixed on a carriage 4 sliding on a transverse slide 6 secured to the frame 8 of the machine, as it is well known.
L'appareil à affûter, qui porte la référence générale 10, a pour fonction d'affiler les faces supérieure 12 et inférieure 12' du tranchant de la lame de coupe 2. The function of the sharpening device, which has the general reference 10, is to sharpen the upper 12 and lower 12 ′ faces of the cutting edge of the cutting blade 2.
L'appareil 10 comprend deux tronçons 14-14' de fusil à affiler, dit '!fusil de boucher", dont chacun est fixé à l'extrémité d'une lame de ressort 16-16' dont les extrémités opposées sont fixées, au moyen de vis 18-18' sur un support 20 solidaire du bâti 8 de la machine. The apparatus 10 comprises two sections 14-14 'of sharpening steel, called'! Butcher's rifle ', each of which is fixed to the end of a leaf spring 16-16' whose opposite ends are fixed, to the screw means 18-18 'on a support 20 secured to the frame 8 of the machine.
Comme on le voit sur la figure 1, les lames de ressort 16-16' et les tronçons de fusil 14-14' qui y sont fixés font entre eux, vus suivant le plan vertical de la figure 1, un angle alpha sensiblement identique à l'angle des tranchants 12-12' de la lame de coupe Mais, comme on le voit sur les figures 2 et 3, les tronçons de fusil 14-14' sont également croisés entre eux, vus suivant un plan horizontal, de façon à porter l'un contre l'autre au voisinage de leurs extrémités, dans la zone d'affûtage de la lame. As can be seen in FIG. 1, the leaf springs 16-16 ′ and the sections of rifle 14-14 ′ which are attached to them make between them, seen along the vertical plane of FIG. 1, an angle alpha substantially identical to the angle of the cutting edges 12-12 ′ of the cutting blade But, as can be seen in FIGS. 2 and 3, the rifle sections 14-14 ′ are also crossed between them, seen in a horizontal plane, so as to wear one against the other near their ends, in the sharpening area of the blade.
Des moyens de réglage de la position et de i'orientation des lames de ressort 16-16' sont prévus pour permettre d'ajuster la position des tronçons de fusil 14-14' par rapport à la lame. Ces moyens peuvent etre constitués par les vis de fixation 18-18' qui passent dans des boutonnières 22-22' ménagés dans les lames 16-16'. Means for adjusting the position and orientation of the spring blades 16-16 'are provided to allow the position of the rifle sections 14-14' to be adjusted relative to the blade. These means can be constituted by the fixing screws 18-18 'which pass through buttonholes 22-22' formed in the blades 16-16 '.
Comme on le voit sur la figure 3, on peut utiliser des tronçons 14-14' pris dans un fusil de boucher de section demi-ronde, mais une section demi-ovale convient également. La demanderesse a observé qu'elle obtenait des résultats satisfaisants avec des tronçons pris dans un fusil de 14mm de diamètre présentant des stries fines d'affilage, dans le sens longitudinal, espacées de 0,1 à 0,2mm. As seen in Figure 3, one can use sections 14-14 'taken in a butcher rifle with a half-round section, but a half-oval section is also suitable. The Applicant has observed that it obtains satisfactory results with sections taken in a rifle of 14mm in diameter having fine streaks of sharpening, in the longitudinal direction, spaced from 0.1 to 0.2mm.
Comme on le voit d'après ce qui précède, l'inertie des deux parties de l'appareil d'affûtage est très réduite, ce qui diminue les risques de chocs et de rebondissements à la rencontre des fusils avec la lame. D'autre part, l'aiguisage au fusil n'enlève que très peu de matière pour maintenir le tranchant, si bien qu'on obtient une durée de vie plus longue des lames qu'avec les appareils à affûter à pierres et la fréquence des réglages de la lame est diminuée, ce qui est particulièrement avantageux sur les machines à tisser à grande vitesse. As can be seen from the above, the inertia of the two parts of the sharpening device is very small, which reduces the risk of shocks and twists when the rifles meet the blade. On the other hand, sharpening with a rifle removes very little material to maintain the cutting edge, so that the blades have a longer lifespan than with stone sharpeners and the frequency of blade settings is decreased, which is particularly advantageous on high speed weaving machines.
