Abstract

A trolley for moving textile pieces between workstations comprises a clamp with two parallel branches. One branch can be maneuvered by means of a perpendicular arm associated with another ratchet. The other is fixed and coaxial with a disk associated with a ratchet whereby its orientation may be varied. The clamp is mounted on a crossmember of a movable member of a vertical jack. The jack is disposed between two tubular columns which guide the crossmember and one of which has at its upper end a quick-release connector. This is used to connect the jack to a compressed air supply.

Description

Chariot de manutention pour pièces textiles entre postes de travail.Handling cart for textile parts between work stations.

L'invention a pour objet un chariot perfectionné spécialement conçu pour la manutention entre des postes de travail successifs de pièces textiles utilisées pour la confection de vêtements.The subject of the invention is an improved trolley specially designed for the handling between successive workstations of textile parts used for making clothes.

On sait que dans la confection en série des vêtements, on découpe des pièces dans des matelas de nombreuses étoffes superposées puis on assemble ensuite ces pièces en travaillant sur des lots qui sont déplacés de poste en poste. La manière la plus primitive d'assurer un tel déplacement discontinu consiste à se servir de paniers que l'on porte; ensuite, on a employé des chariots ordinaires. L'évolution se poursuivant on a abouti à des chaînes sans fin à circulation continue des pièces suspendues à des pinces, avec des branches de dérivation à chaque poste de travail. Une telle installation automatisée est coûteuse; elle ne se justifie pas au point de vue économique dans les ateliers de confection de dimensions plutôt faibles et de capacité de production relativement réduite.We know that in the mass production of clothes, pieces are cut from mattresses of many superimposed fabrics and then these pieces are assembled by working on batches which are moved from post to post. The most primitive way of ensuring such a discontinuous movement consists in using the baskets which one carries; then we used ordinary carts. As the evolution continued, we ended up with endless chains with continuous circulation of the pieces suspended from clamps, with branch branches at each work station. Such an automated installation is expensive; it is not justified from the economic point of view in garment workshops of rather small dimensions and relatively reduced production capacity.

Le document FR-A-1 448 956 décrit un chariot roulant comprenant une plateforme au-dessus de laquelle s'étendent horizontalement les deux branches antagonistes d'une pince; celle-ci est montée sur un élément vertical télescopique réglable manuellement en hauteur et qui occupe toujours une même orientation de sorte que la pince elle-même n'est pas orientable en position autour d'un axe horizontal.Document FR-A-1 448 956 describes a rolling carriage comprising a platform above which the two opposing arms of a clamp extend horizontally; it is mounted on a telescopic vertical element manually adjustable in height and which always occupies the same orientation so that the clamp itself cannot be oriented in position around a horizontal axis.

Le but principal de l'invention est donc d'apporter un chariot de manutention perfectionné de façon qu'il permette la plus grande commodité d'emploi et de réduction des gestes et, par conséquent, la plus grande économie de temps sur les opérations de manutention entre les postes de travail, en particulier par l'orientation possible de la pince et, en supplément, par le soulevement motorisé et non plus manuel, de cette pince.The main object of the invention is therefore to provide an improved handling trolley so that it allows the greatest convenience of use and reduction of gestures and, consequently, the greatest saving of time on the operations of handling between workstations, in particular by the possible orientation of the clamp and, in addition, by the motorized lifting and no longer manual, of this clamp.

A partir d'un chariot comprenant une plateforme montée sur roues, un vérin supporté par cette plateforme à une position essentiellement verticale, un élément mobile en montée et en descente faisant partie du vérin, une pince fixée à l'extrémité libre de l'élément mobile et comprenant d'une part deux branches antagonistes s'étendant substantiellement au-dessus de la plateforme parallèlement à celle-ci, d'autre part un moyen de manoeuvre de rapprochement et d'éloignement l'une de l'autre des branches antagonistes, l'une des branches étant réunie à l'élément mobile, un bras étant fixé à l'autre branche perpendiculairement à celle-ci et monté libre en coulissement dans son sens longitudinal par rapport audit élément mobile, un moyen de blocage étant prévu pour immobiliser ce bras en position par rapport à cet élément mobile, selon l'invention ledit élément mobile porte un arbre substantiellement parallèle à la plateforme, libre en rotation dans cet élément mobile et portant un support auquel est fixée l'une des branches et dans lequel est monté coulissant le bras, cependant qu'un moyen de blocage est prévu pour immobiliser ledit arbre à une position quelconque de sa rotation.From a carriage comprising a platform mounted on wheels, a jack supported by this platform in an essentially vertical position, a movable element going up and down forming part of the jack, a clamp fixed to the free end of the element mobile and comprising on the one hand two antagonistic branches extending substantially above the platform parallel to the latter, on the other hand a means of maneuver bringing the antagonistic branches towards and away from each other , one of the branches being joined to the mobile element, an arm being fixed to the other branch perpendicular thereto and mounted to slide freely in its longitudinal direction relative to said mobile element, a locking means being provided for immobilize this arm in position relative to this mobile element, according to the invention said mobile element carries a shaft substantially parallel to the platform, free to rotate in this mobile element and carrying a support auqu el is fixed one of the branches and in which is slidably mounted the arm, however that a locking means is provided to immobilize said shaft at any position of its rotation.

De préférence, le support est un disque ayant à sa périphérie des encoches espacées circonférentiellement destinées à recevoir une extrémité d'un cliquet monté sur l'élément mobile, ce disque constituant le moyen de guidage en coulissement longitudinal du bras portant à une extrémité une branche de la pince, l'autre branche de celle-ci étant fixée à ce disque coaxialement à l'arbre, des dépressions étant espacées longitudinalement sur une face du bras et un petit cliquet étant prévu en correspondance sur le disque.Preferably, the support is a disc having at its periphery circumferentially spaced notches intended to receive one end of a pawl mounted on the mobile element, this disc constituting the guide means in longitudinal sliding of the arm carrying at one end a branch of the clamp, the other branch of the latter being fixed to this disc coaxially with the shaft, depressions being spaced longitudinally on one face of the arm and a small pawl being provided correspondingly on the disc.

De préférence encore, le petit cliquet est monté à l'intérieur d'un logement creusé dans le disque et débouchant dans une ouverture diamétrale de coulissement du bras, ce petit cliquet étant en outre porté par un arbre traversant le disque et accessible extérieurement à ce dernier.More preferably, the small pawl is mounted inside a housing hollowed out in the disc and opening into a diametrical sliding opening of the arm, this small pawl also being carried by a shaft passing through the disc and accessible from outside. latest.

Selon un perfectionnement de l'invention, le vérin est un vérin pneumatique disposé entre deux colonnes tubulaires verticales. L'élément mobile est pourvu de deux coulisseaux montés coulissant respectivement chacun sur une colonne tubulaire. A son extrémité supérieure libre éloignée de la plateforme, l'une des colonnes est munie d'un embout de raccordement rapide à un réseau d'air comprimé; à son extrémité inférieure, cette colonne est raccordée au cylindre du vérin par l'intermédiaire d'un distributeur d'alimentation et d'échappement à élément de commande. De préférence, cet élément de commande est relié à un bouton de commande monté à l'extrémité supérieure de l'autre colonne tubulaire.According to an improvement of the invention, the jack is a pneumatic jack arranged between two vertical tubular columns. The movable element is provided with two slides mounted to slide each on a tubular column, respectively. At its free upper end remote from the platform, one of the columns is provided with a nozzle for quick connection to a compressed air network; at its lower end, this column is connected to the cylinder of the jack via a supply and exhaust distributor with control element. Preferably, this control element is connected to a control button mounted at the upper end of the other tubular column.

De manière avantageuse, la partie extrême du bras se prolongeant au-delà du moyen de guidage est terminée par une poignée.Advantageously, the end part of the arm extending beyond the guide means is terminated by a handle.

On donnera maintenant, sans intention limitative et sans exclure aucune variante, une description d'un exemple de réalisation. On se rapportera aux dessins annexés dans lesquels:

  • la figure 1 est une vue générale en perspective de dessus d'un chariot de manutention conforme à l'invention,
  • la figure 2 est une représentation schématique du même chariot permettant de mieux en expliquer la constitution,
  • la figure 3 est une vue agrandie de détail montrant en coupe par un plan passant par l'axe les deux encliquetages combinés d'une part du serrage de la pince, d'autre part de son orientation.
We will now give, without limiting intention and without excluding any variant, a description of an exemplary embodiment. Reference will be made to the appended drawings in which:
  • FIG. 1 is a general perspective view from above of a handling trolley according to the invention,
  • FIG. 2 is a schematic representation of the same carriage making it possible to better explain its constitution,
  • Figure 3 is an enlarged detail view showing in section through a plane passing through the axis the two combined snaps on the one hand of the clamp clamp, on the other hand its orientation.

Un chariot conforme à l'invention comprend une plateforme 1 montée sur quatre roues orientables 2 et supportant sur un de ses bords un vérin vertical 3 qui est de préférence un vérin pneumatique. Ce dernier comprend un élément 4 mobile verticalement en montée et en descente à l'extrémité libre de laquelle est montée une pince 5. Celle-ci a deux branches antagonistes 6A, 6B, allongées parallèles, s'étendant au-dessus de la plateforme 1. Ces deux branches 6A, 6B peuvent être rapporchées et éloignés l'une de l'autre par un moyen de manouvre pour pouvoir tenir serré entre elles un lot de pièces d'étoffe ou de vêtements en cours de confection comme ou peut le voir sur la figure 1.A trolley according to the invention comprises a platform 1 mounted on four steerable wheels 2 and supporting on one of its edges a vertical cylinder 3 which is preferably a pneumatic cylinder. The latter comprises an element 4 movable vertically up and down at the free end of which is mounted a clamp 5. This has two opposing branches 6A, 6B, elongated parallel, extending above the platform 1 These two branches 6A, 6B can be brought together and separated from each other by a maneuvering means in order to be able to hold tightly together a batch of pieces of fabric or of clothing being made as or can be seen on Figure 1.

Le vérin 3 est dressé entre deux colonnes tubulaires verticales 7, 8 sur chacune desquelles est monté coulissant un coulisseau 7A, 7B respectivement. Ces derniers sont reliés par une traverse 9 qui fait partie de l'élément 4 mobile verticalement. On obtient ainsi un bon guidage de ce dernier.The jack 3 is erected between two vertical tubular columns 7, 8 on each of which is slidably mounted a slide 7A, 7B respectively. These are connected by a cross member 9 which is part of the vertically movable element 4. This gives good guidance of the latter.

A l'intérieur de la traverse 9 (figure 3) est monté un arbre 10, parallèle à la plateforme 1, libre en rotation, dont une extrémité OA dirigée du côté de la pince 5 porte un disque 11 cylindrique à la périphérie ex- rieure duquel sont creusées huit encoches 12 espacées circonférentiellement dans des plans radiaux. Au sommet de la traverse 9 est prévue une fente longitudinale 13 dans laquelle est montée pivotante autour d'un axe 14transversal à cette fente 13 un cliquet 15. Ce dernier a une première extrémité 15A conformée et dimensionnée pour pouvoir s'engager dans les encoches 12 du disque 11; la seconde extrémité opposée 15B du cliquet 15 déborde de la traverse 9 et peut être saisie facilement. Un ressort (non représenté) tient élastiquement le cliquet 15 engagé dans l'une quelconque des encoches 12. En abaissant l'extrémité 15B de ce cliquet 1 on fait sortir son extrémité 15A de l'encoche 12 dans laquelle elle est engagée et on peut donner au disque 11 une orientation différente.Inside the cross-member 9 (FIG. 3) is mounted a shaft 10, parallel to the platform 1, free to rotate, of which one end OA directed towards the side of the clamp 5 carries a cylindrical disc 11 at the outer periphery from which eight notches 12 are hollowed out circumferentially spaced in radial planes. At the top of the cross member 9 is provided a longitudinal slot 13 in which is pivotally mounted about an axis 14 transverse to this slot 13 a pawl 15. The latter has a first end 15A shaped and dimensioned to be able to engage in the notches 12 disc 11; the second opposite end 15B of the pawl 15 projects beyond the cross-member 9 and can be grasped easily. A spring (not shown) resiliently holds the pawl 15 engaged in any one of the notches 12. By lowering the end 15B of this pawl 1, its end 15A comes out of the notch 12 in which it is engaged and it is possible to give disc 11 a different orientation.

Le disque 11 sert aussi de moyen de guidage en coulissement à un bras 17 grâce à une ouverture diamétrale 16 ménagée dans son épaisseur et dont le profil et les dimensions correspondent à ceux de ce bras 17. Ce dernier est muni à une extrémité de la branche 6A, qui lui est perpendiculaire, de la pince 5 et à son extrémité opposée d'une poignée 18 qui facilite sa préhension pour le faire coulisser à travers le disque 11.The disc 11 also serves as a sliding guide means for an arm 17 thanks to a diametrical opening 16 formed in its thickness and whose profile and dimensions correspond to those of this arm 17. The latter is provided at one end of the branch 6A, which is perpendicular thereto, of the clamp 5 and at its opposite end of a handle 18 which facilitates its gripping in order to make it slide through the disc 11.

Sur sa face extrême libre 11A, le disque 11 est muni de la branche 6B de la pince 5; cette branche 6B s'étend perpendiculairement au disque 11, coaxialement à l'arbre 10. Elle est fixe, par opposition à la branche antagoniste 6A qui peut être déplacée parallèlement à elle-même au moyen du bras 17. Un moyen de blocage en position de ce bras 17 est constitué de préférence de la façon suivante. Dans la face latérale du bras 17 située du côté de l'arbre 10 et de la traverse 9 sont prévues des dépressions successives 19 espacées régulièrement dans le sens de la longueur de ce bras 17. Dans le disque 11 est creusé un logement 20 qui s'ouvre dans l'ouverture diamétrale 1 sur le trajet suivi par les dépressions 19 quand le bras 17 coulisse. Dans le logement 20 est disposé un petit cliquet 21 porté par un arbre 22 qui traverse le logement 20 et le disque 11 grâce à un trou 23 percé à travers ce dernier orthogonalement à son axe géométrique. L'arbre 22 est accessible à une extrémité du trou 23 et il est mobile en rotation contre l'effet d'un ressort de rappel (non représenté). Le petit cliquet 21 est repoussé sous l'action de ce ressort à une première position, visible sur la figure 3, où sa partie extrême est engagée dans l'une quelconque des encoches 19. En agissant sur l'arbre 22, on peut mettre le petit cliquet 21 à sa seconde position où il est totalement escamoté dans le logement 20 de sorte qu'il laisse le bras 17 libre de coulisser dans l'ouverture diamétrale 16.On its free end face 11A, the disc 11 is provided with the branch 6B of the clamp 5; this branch 6B extends perpendicular to the disc 11, coaxially with the shaft 10. It is fixed, as opposed to the opposing branch 6A which can be moved parallel to itself by means of the arm 17. A locking means in position this arm 17 is preferably made up as follows. In the lateral face of the arm 17 located on the side of the shaft 10 and of the cross-member 9 are provided successive depressions 19 regularly spaced in the direction of the length of this arm 17. In the disc 11 is hollowed out a housing 20 which s 'opens in the diametrical opening 1 on the path followed by the depressions 19 when the arm 17 slides. In the housing 20 is disposed a small pawl 21 carried by a shaft 22 which passes through the housing 20 and the disc 11 by means of a hole 23 drilled through the latter orthogonally to its geometric axis. The shaft 22 is accessible at one end of the hole 23 and it is movable in rotation against the effect of a return spring (not shown). The small pawl 21 is pushed back under the action of this spring to a first position, visible in FIG. 3, where its end part is engaged in any one of the notches 19. By acting on the shaft 22, it is possible to put the small pawl 21 in its second position where it is completely retracted into the housing 20 so that it leaves the arm 17 free to slide in the diametrical opening 16.

De préférence, les dépressions 19 ont une face 19A inclinée qui permet de faire battre le petit cliquet 21 quand on tire sur le bras 17 pour rapprocher la branche 6A de la branche 6B de la pince 5 afin de serrer des vêtements dans celle-ci. Les dépressions 19 ont une autre face 19B inclinée pour que le petit cliquet 21 vienne buter contre elle par sa partie extrême 21 A quand elle n'a pas été escamotée dans le logement 20 par la rotation de l'arbre 22. La compression et le poids des vêtements serrés dans la pince 5 ne peuvent donc pas provoquer son ouverture, quelle que soit l'orientation que l'on donne à cette pince 5 en faisant tourner la branche 6B et l'arbre 10. Dans cet exemple, le petit cliquet 21 est une pièce ronde visible sur la figure 2, engagée partiellement dans une fente correspondante 24 prévue dans l'arbre 22.Preferably, the depressions 19 have an inclined face 19A which makes it possible to cause the small pawl 21 to beat when one pulls on the arm 17 in order to bring the branch 6A of the branch 6B of the clamp 5 in order to tighten clothes therein. The depressions 19 have another inclined face 19B so that the small pawl 21 abuts against it by its end portion 21 A when it has not been retracted into the housing 20 by the rotation of the shaft 22. The compression and the weight of the clothes tightened in the clamp 5 cannot therefore cause it to open, whatever the orientation that this clip 5 is given by rotating the branch 6B and the shaft 10. In this example, the small pawl 21 is a round part visible in FIG. 2, partially engaged in a corresponding slot 24 provided in the shaft 22.

La colonne tubulaire verticale 7 est munie à son extrémité supérieure libre d'un embout 25 permettant son raccordement rapide à une canalisation d'alimentation en air sous pression; elle est étanche et son extrémité inférieure est reliée par une tubulure 26 à l'extrémité inférieure du vérin 3 par l'intermédiaire d'un distributeur 27 ayant un élément de commande et un orifice d'échappement d'air situés à l'extrémité inférieure de la colonne tubulaire verticale 6. A l'intérieur de celle-ci une tringle 28 relie l'élément de commande du distributeur 27 à un bouton 29 situé au sommet de cette colonne tubulaire 6.The vertical tubular column 7 is provided at its free upper end with a nozzle 25 allowing its rapid connection to a pipe for supplying air under pressure; it is sealed and its lower end is connected by a tube 26 to the lower end of the jack 3 by means of a distributor 27 having a control element and an air exhaust orifice situated at the lower end of the vertical tubular column 6. Inside thereof a rod 28 connects the control element of the distributor 27 to a button 29 located at the top of this tubular column 6.

Le chariot de l'invention permet de serrer et de desserrer rapidement un lot de pièces à coudre, ou de vêtements en cours de confection, dans la pince 5, d'orienter facilement celle-ci à-la position la plus favorable au travail.
