- the shape is constituted by two pairs of parallel rods, each pair comprising a fixed rod and a transversely movable rod, that the pantyhose is introduced manually on this form, that the two movable rods then move apart to stretch the pantyhose transversely, that after visual control of the pantyhose the movable rods return to their original position and that the pantyhose is finally ejected by a jet compressed air directed inside.
- the performance of such devices is low because of the need for complete manual introduction of the tights onto the form.
- DE-A-1 410 870 certainly offers a control device in which pressurized air curtains are provided to activate the placement of stockings on forms for their control.
- the output can then be very improved, but the control lacks reliability, because two air curtains act obliquely from top to bottom on either side of the forms on which the stockings are themselves introduced vertically from top to bottom. It turns out in fact that this vertical introduction from top to bottom is harmful, because the speed of fitting the stockings leads to the formation of "pockets" in the stockings.
- the stockings may therefore not be completely and sufficiently stretched, which makes rigorous control impossible.
- the invention eliminates these drawbacks. It relates to an apparatus which is of the type comprising, on the one hand, in front of a light table, an extendable shape constituted by two pairs of arms, two arms of which fixed and two transversely movable arms, and on the other hand means triggering the formation of a curtain of pressurized air acting obliquely on the tights or other textile article in the direction of the high or open side end of this article, for drag it and insert it automatically and completely on the form.
- the light table is traversed over its entire thickness by oblique holes which open into a box or into a common channel of compressed air located behind the table and which serve as nozzles for the formation of a air curtain directed obliquely in front of the table and from bottom to top, in the direction of insertion of the stockings on the form.
- holes are preferably located along two parallel lines disposed in front of the fixed arms of the two forms, and the spacing of the holes is advantageously irregular from one to the other on the same line, this spacing increasing from the free end of each arm of the form in the direction of its fixed end.
- the nozzles for the formation of the compressed air curtain are provided in a fixed member of the form.
- means are provided for connecting the nozzles to a source of compressed air which intervenes automatically when a sticker is presented manually on the device.
- the oblique curtain of compressed air then alone achieves the complete transfer of the tights to the form.
- This clearance can be obtained in various ways. If the light table is vertical or is placed in an inclined plane close to the vertical, the sticky can descend under the simple effect of gravity, while advantageously being sucked into a box located at the bottom of the device and in which a vacuum reigns periodically. It is however also possible to accelerate the release of the pantyhose by an oblique compressed air jet acting on the pantyhose in the direction opposite to that of the air curtain used for the introduction of the pantyhose on the form.
- the device is in the general form of a box-shaped box which, placed in a plane close to the vertical, is generally designated by 1.
- the inclination of this the desk is also advantageously adjustable at the whim of the person carrying out the quality control of the tights.
- This desk essentially comprises a light table 2 constituted by a translucent surface behind which are placed lighting tubes not visible in the drawing. In front of this light table is placed the shape to receive one by one the tights to be checked.
- This shape which is generally designated by 3, consists of four transparent glass blades, arranged in two pairs, namely for each pair a fixed blade and a movable blade.
- the two fixed blades are designated by 4 and 5.
- the two movable blades are designated by 6 and 7; they are parallel to the two fixed blades 4 and 5; they are located in front of them and they can be moved laterally in the direction of the outside with respect to the two fixed blades 4 and 5.
- Supports not shown in the drawing are provided at the top to support the four blades of the shape .
- the supports of the two movable blades 6 and 7 make it possible to give them the movements necessary successively for their spacing and their approximation relative to the corresponding fixed blades 4 and 5.
- holes 8 are arranged in the plate 2 serving as a light table. These holes 8 are oblique; and their obliquity is such that these holes go up from the rear towards the front of the light table; they therefore go up in the direction of the form 4, 5, 6, 7. These holes 8 open out on the front face of the light table 2; and they emerge by their rear end either in a box, or in a pipe, box or pipe which is not shown in the drawing, but in which compressed air is admitted automatically and programmed.
- the holes 8 are arranged in two parallel lines visible in Figure 5, behind the two fixed blades 4 and 5 of the shape.
- the spacing of the holes 8 on each line is not regular; on the contrary, it is irregular, increasing from the bottom to the top of the shape.
- FIG. 2 illustrates this phase from which, from the moment when manually the introduction of the tights has been initiated on the form, the compressed air is admitted through the holes 8 of the light table 2. This results in the forming an oblique sheet of compressed air 11.
- This sheet which moves from bottom to top drives the tights up until the closed ends of the tights, that is to say the ends of the two legs, come to rest on the base of the form.
- This is the position shown in Figure 3, position in which the two legs of the pantyhose respectively cover one of the blades 4 and 6 of the shape and the other the blades 5 and 7 of the shape.

- this device is suitable for transferring these products for ironing.
Abstract
Description
Il est habituel de contrôler la qualité des bas, des collants et autres articles similaires après leur fabrication, mais avant leur conditionnement, voir par exemple US-A-3 730 405. Ce contrôle est le plus souvent fait visuellement après que l'article ait été introduit sur une forme permettant de l'étirer transversalement, en avant d'une plaque ou table lumineuse grâce à laquelle il est possible de déceler les défauts éventuels de cet article.It is usual to check the quality of the stockings, tights and other similar articles after their manufacture, but before their packaging, see for example US-A-3,730,405. This check is most often done visually after the article has was introduced on a form allowing to stretch it transversely, in front of a light plate or table thanks to which it is possible to detect the possible defects of this article.
Divers moyens sont utilisés pour permettre l'introduction de l'article sur la forme, l'extension transversale de la forme et le dégagement de l'article après son contrôle.Various means are used to allow the article to be introduced onto the form, the transverse extension of the form and the release of the article after it has been checked.
Dans le but d'illustrer l'état antérieur de la technique, il est rappelé que dans certains appareils pour le contrôle des collants, la forme est constituée par deux paires de tiges parallèles, chaque paire comportant une tige fixe et une tige transversalement mobile, que le collant est introduit manuellement sur cette forme, que les deux tiges mobiles s'écartent ensuite pour étirer transversalement le collant, qu'après contrôle visuel du collant les tiges mobiles reviennent à leur position primitive et que le collant est finalement éjecté par un jet d'air comprimé dirigé à son intérieur. Le rendement de tels appareils est faible à cause de la nécessité d'introduction manuelle complète du collant sur la forme.With the aim of illustrating the prior art, it is recalled that in certain devices for the control of tights, the shape is constituted by two pairs of parallel rods, each pair comprising a fixed rod and a transversely movable rod, that the pantyhose is introduced manually on this form, that the two movable rods then move apart to stretch the pantyhose transversely, that after visual control of the pantyhose the movable rods return to their original position and that the pantyhose is finally ejected by a jet compressed air directed inside. The performance of such devices is low because of the need for complete manual introduction of the tights onto the form.
Le DE-A-1 410 870 propose certes un appareil de contrôle dans lequel des rideaux d'air sous pression sont prévus pour activer la mise en place de bas sur des formes en vue de leur contrôle. Le rendement peut alors être très amélioré, mais le contrôle manque de fiabilité, car deux rideaux d'air agissent obliquement de haut en bas de part et d'autre des formes sur lesquelles les bas sont eux-mêmes introduits verticalement de haut en bas. Il s'avère en fait que cette introduction verticale de haut en bas est néfaste, car la rapidité de mise en place des bas amène la formation de "poches" dans les bas. Les bas risquent donc de ne pas être complètement et suffisamment tendus, ce qui rend alors impossible un contrôle rigoureux.DE-A-1 410 870 certainly offers a control device in which pressurized air curtains are provided to activate the placement of stockings on forms for their control. The output can then be very improved, but the control lacks reliability, because two air curtains act obliquely from top to bottom on either side of the forms on which the stockings are themselves introduced vertically from top to bottom. It turns out in fact that this vertical introduction from top to bottom is harmful, because the speed of fitting the stockings leads to the formation of "pockets" in the stockings. The stockings may therefore not be completely and sufficiently stretched, which makes rigorous control impossible.
L'invention écarte ces inconvénients. Elle a pour objet un appareil qui est du type comportant, d'une part, en avant d'une table lumineuse une forme extensible constituée par deux paires de bras, dont deux bras fixes et deux bras transversalement mobiles, et d'autre part des moyens déclenchant la formation d'un rideau d'air sous pression agissant obliquement sur le collant ou autre article textile en direction de l'extrémité côté haut ou ouvert de cet article, pour le faire glisser et l'introduire automatiquement et totalement sur la forme. Selon l'invention, la table lumineuse est traversée sur toute son épaisseur par des perçages obliques qui débouchent dans un caisson ou dans un canal commun d'air comprimé situé en arrière de la table et qui servent d'ajutages pour la formation d'un rideau d'air dirigé obliquement en avant de la table et de bas en haut, dans le sens d'introduction des bas sur la forme.The invention eliminates these drawbacks. It relates to an apparatus which is of the type comprising, on the one hand, in front of a light table, an extendable shape constituted by two pairs of arms, two arms of which fixed and two transversely movable arms, and on the other hand means triggering the formation of a curtain of pressurized air acting obliquely on the tights or other textile article in the direction of the high or open side end of this article, for drag it and insert it automatically and completely on the form. According to the invention, the light table is traversed over its entire thickness by oblique holes which open into a box or into a common channel of compressed air located behind the table and which serve as nozzles for the formation of a air curtain directed obliquely in front of the table and from bottom to top, in the direction of insertion of the stockings on the form.
Ces perçages sont de préférence situés suivant deux lignes parallèles disposées en avant des bras fixes des deux formes, et l'écartement des perçages est avantageusement irrégulier de l'un à l'autre sur une même ligne, cet écartement allant en augmentant à partir de l'extrémité libre de chaque bras de la forme en direction de son extrémité fixe.These holes are preferably located along two parallel lines disposed in front of the fixed arms of the two forms, and the spacing of the holes is advantageously irregular from one to the other on the same line, this spacing increasing from the free end of each arm of the form in the direction of its fixed end.
Suivant une variante d'exécution de l'invention, les ajutages pour la formation du rideau d'air comprimé sont prévus dans un organe fixe de la forme.According to an alternative embodiment of the invention, the nozzles for the formation of the compressed air curtain are provided in a fixed member of the form.
Quelle que soit la forme d'exécution, des moyens sont prévus pour raccorder les ajutages à une source d'air comprimé intervenant automatiquement lorsqu'un collant est présenté manuellement sur l'appareil. Le rideau oblique d'air comprimé réalise alors à lui seul le transfert complet du collant sur la forme. Lorsque le collant a ainsi été totalement mis en place, la forme s'ouvre en étirant transversalement le collant qui peut ainsi être contrôlé; et à l'issue de ce contrôle, la forme se resserre et le collant se dégage de la forme.Whatever the embodiment, means are provided for connecting the nozzles to a source of compressed air which intervenes automatically when a sticker is presented manually on the device. The oblique curtain of compressed air then alone achieves the complete transfer of the tights to the form. When the pantyhose has thus been completely put in place, the shape opens by stretching the pantyhose transversely which can thus be checked; and at the end of this control, the shape tightens and the tights are released from the shape.
Ce dégagement peut être obtenu de diverses façons. Si la table lumineuse est verticale ou est placée dans un plan incliné proche de la verticale, le collant peut redescendre sous le simple effet de la gravité, tout en étant avantageusement aspiré dans un caisson situé en bas de l'appareil et dans lequel une dépression règne périodiquement. Il est toutefois aussi possible d'accélérer le dégagement du collant par un jet d'air comprimé oblique agissant sur le collant en direction opposée à celle du rideau d'air utilisé pour l'introduction du collant sur la forme.This clearance can be obtained in various ways. If the light table is vertical or is placed in an inclined plane close to the vertical, the sticky can descend under the simple effect of gravity, while advantageously being sucked into a box located at the bottom of the device and in which a vacuum reigns periodically. It is however also possible to accelerate the release of the pantyhose by an oblique compressed air jet acting on the pantyhose in the direction opposite to that of the air curtain used for the introduction of the pantyhose on the form.
L'invention sera bien comprise d'ailleurs à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de cet appareil, dans le cas où il est destiné au contrôle visuel de la qualité de collants:
- Figure 1 en est une vue générale en perspective en position de repos;
- Figures 2, 3 et 4 sont des vues en perspective illustrant diverses phases de son fonctionnement;
- Figure 5 en est une vue de face avant, et
- Figure 6 en est, à plus grande échelle, une vue en coupe verticale.
- Figure 1 is a general perspective view in the rest position;
- Figures 2, 3 and 4 are perspective views illustrating various phases of its operation;
- Figure 5 is a front view, and
- Figure 6 is, on a larger scale, a vertical sectional view.
Comme le montrent les figures 1 à 4, l'appareil se présente sous la forme générale d'un caisson en forme de pupitre qui, placé dans un plan proche de la verticale, est désigné de façon générale par 1. L'inclinaison de ce pupitre est d'ailleurs avantageusement réglable au gré de la personne effectuant le contrôle de la qualité des collants. Ce pupitre comporte essentiellement une table lumineuse 2 constituée par une surface translucide en arrière de laquelle sont placés des tubes d'éclairage non visibles au dessin. En avant de cette table lumineuse est placée la forme devant recevoir un à un les collants à contrôler.As shown in Figures 1 to 4, the device is in the general form of a box-shaped box which, placed in a plane close to the vertical, is generally designated by 1. The inclination of this the desk is also advantageously adjustable at the whim of the person carrying out the quality control of the tights. This desk essentially comprises a light table 2 constituted by a translucent surface behind which are placed lighting tubes not visible in the drawing. In front of this light table is placed the shape to receive one by one the tights to be checked.
Cette forme, qui est désignée de façon générale par 3, est constituée par quatre lames en verre transparent, disposées suivant deux paires, à savoir pour chaque paire une lame fixe et une lame mobile. Les deux lames fixes sont désignées par 4 et 5. Les deux lames mobiles sont désignées par 6 et 7; elles sont parallèles aux deux lames fixes 4 et 5; elles sont situées en avant par rapport à elles et elles sont déplaçables latéralement en direction de l'extérieur par rapport aux deux lames fixes 4 et 5. Des supports non représentés au dessin sont prévus à la partie supérieure pour soutenir les quatre lames de la forme. Les supports des deux lames mobiles 6 et 7 permettent de leur donner les mouvements nécessaires successivement à leur écartement et à leur rapprochement par rapport aux lames fixes correspondantes 4 et 5.This shape, which is generally designated by 3, consists of four transparent glass blades, arranged in two pairs, namely for each pair a fixed blade and a movable blade. The two fixed blades are designated by 4 and 5. The two movable blades are designated by 6 and 7; they are parallel to the two
Selon une caractéristique essentielle de l'invention, des perçages 8 sont aménagés dans la plaque 2 servant de table lumineuse. Ces perçages 8 sont obliques; et leur obliquité est telle que ces perçages vont en montant de l'arrière en direction de l'avant de la table lumineuse; ils vont donc en montant en direction de la forme 4, 5, 6, 7. Ces perçages 8 débouchent à l'extérieur sur la face avant de la table lumineuse 2; et ils débouchent par leur extrémité arrière soit dans un caisson, soit dans une canalisation, caisson ou canalisation qui n'est pas représenté au dessin, mais dans lequel de l'air comprimé est admis de façon automatique et programmée.According to an essential characteristic of the invention, holes 8 are arranged in the
Les perçages 8 sont disposés suivant deux lignes parallèles visibles sur la figure 5, en arrière des deux lames fixes 4 et 5 de la forme. L'écartement des perçages 8 sur chaque ligne n'est pas régulier; il est au contraire irrégulier, allant en augmentant de la partie inférieure à la partie supérieure de la forme.The holes 8 are arranged in two parallel lines visible in Figure 5, behind the two
Lorsque l'appareil est au repos, les deux lames mobiles 6 et 7 de la forme sont placées en avant, en superposition par rapport aux deux lames fixes 4 et 5; c'est la position représentée à la figure 1.When the device is at rest, the two
Dans cette position peut être introduit un collant désigné de façon générale par 9. L'introduction du collant est faite manuellement sur la forme 4, 5, 6, 7 à partir de la partie supérieure du collant, c'est-à-dire sa partie culotte. La figure 2 illustre cette phase à partir de laquelle, dès l'instant où manuellement l'introduction du collant a été amorcée sur la forme, l'air comprimé est admis au travers des perçages 8 de la table lumineuse 2. Il en résulte la formation d'une nappe oblique d'air comprimé 11. Cette nappe qui va en se déplaçant de bas en haut entraîne le collant vers le haut jusqu'à ce que les extrémitéss fermées du collant, c'est-à-dire les extrémités des deux jambes, arrivent en appui sur la base de la forme. C'est la position représentée à la figure 3, position dans laquelle les deux jambes du collant recouvrent respectivement l'une les lames 4 et 6 de la forme et l'autre les lames 5 et 7 de la forme.In this position can be introduced a pantyhose generally designated by 9. The introduction of the pantyhose is done manually on the
Lorsque le collant a ainsi atteint la position visible à la figure 3, les deux lames 6 et 7 de la forme se déplacent latéralement jusqu'à atteindre la position représentée en traits discontinus à la figure 5. Ce mouvement d'ouverture de la forme conduit à une extension transversale du collant. C'est la position représentée à la figure 4, position dans laquelle le contrôle visuel du collant peut être fait en avant de la table lumineuse 2.When the tights have thus reached the position visible in FIG. 3, the two
Lorsque le contrôle est terminé, les deux lames 6 et 7 de la forme reviennent à leur position primitive de la figure 3. Le collant 9 redescend alors sous le simple effet de la pesanteur. Il est toutefois à noter que le dégagement du collant hors de la forme peut avantageusement être accéléré par un jet d'air envoyé de haut en bas sur le collant au travers d'un perçage 10 aménagé dans la table lumineuse 2 en direction inverse des perçages 8.When the control is finished, the two
Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cet appareil de contrôle qui a été ci-dessus indiquée à titre d'exemple; elle en embrasse, au contraire, toutes les variantes de réalisation, quels que soient notamment les moyens utilisés pour créer le rideau oblique d'air sous pression permettant l'introduction rapide et totale du collant sur la forme, ainsi que l'agencement de la forme, et les moyens de contrôle proprement dits, le contrôle pouvant être fait non pas visuellement, mais de façon automatique; et elle étend bien entendu son champ d'application au cas où la forme ne serait composée que de deux lames, soit l'une fixe et l'autre mobile, soit toutes deux mobiles, en vue du contrôle de la qualité de bas et non pas de collants.It goes without saying that the invention is not limited to the single form execution of this recording device which has been indicated above by way of example; on the contrary, it embraces all the variant embodiments thereof, whatever in particular the means used to create the oblique curtain of pressurized air allowing the rapid and total introduction of the tights onto the form, as well as the arrangement of the form, and the means of control proper, the control can be done not visually, but automatically; and it of course extends its field of application to the case where the shape would only be composed of two blades, one fixed and the other mobile, or both mobile, for the purpose of quality control from below and not no tights.
Il est enfin à observer qu'un appareil conforme à l'invention peut être utilisé pour des opérations autres que le visitage de bas ou de collants en vue du contrôle de leur qualité. C'est ainsi par exemple que cet appareil convient au transfert de ces produits en vue de leur repassage.Finally, it should be observed that a device in accordance with the invention can be used for operations other than visiting stockings or tights for the purpose of quality control. For example, this device is suitable for transferring these products for ironing.
