Description
La présente invention a pour objet un dispositif pour le traitement des produits manufacturés tubulaires tricotés, spéciallement bas.The subject of the present invention is a device for processing products knitted tubular products, specially low.
Il est connu que les bas sont fabriqués à partir d'un élément tubulaire tricoté avec les extrémités ouvertes et que, par la suite, un'extrémité de l'élément, c'est-à-dire la pointe du pied, est cousue. La couture de la pointe du pied est réalisée avec une machine à coudre les pointes ou "toe closer" comprenante une pluralité du tubes de support des produits manufacturés à traiter lesquels sont montés sur une structure à caroussel tournante à intermittence ou en continu entre une première station de chargement, renversement et positionnement du produit manufacturé, une deuxième station de positionnement de la pointe à coudre selon la courbure voulue obtenir, une troisième station où est réalisée la couture veritable de la pointe du produit manufacturé et un successive station de déchargement des produits manufacturés ainsi traités.It is known that stockings are made from of a tubular element knitted with the ends open and that thereafter an end of the element, i.e. tiptoe, is sewn. The toe seam is made with a needle sewing machine or "toe closer" including a plurality of the tubes support of manufactured products to be processed which are mounted on a carousel structure intermittently or continuously between a first loading station, overturning and positioning of the manufactured product, a second sewing point positioning station depending on the desired curvature, a third station where the real sewing of the advanced manufactured product and a successive unloading station for manufactured products thus treated.
Il est aussi connu que dans certains cas il est
demandé de réaliser, dans une station
opérationnelle séparée, une coupe longitudinale
desdits produits manufacturés, du côté opposé à
celui de la pointe, le long d'une section de
longueur prédéterminée, pour en permettre
l'accouplement au moyen d'une couture réalisé à la
main en correspondance des bords des bas ainsi
coupés, de manière à en obtenir un collant. Ladite
coupe et ladite couture d'union des deux bas
doivent être opportunement orientées selon un point
de repère local, comme par exemple une direction
prédéterminée par rapport à la ligne de couture de
chaque pointe pour garantir l'adaptation du
vêtement.
Tout ce-ci comporte un temps de réalisation
eccessif par rapport aux exigences actuelles de la
production et oblige à l'emploi de moyens et
personnel préposés spécifiquement à la coupe et au
replacement des produits manufacturés en dehors de
la machine à coudre les pointes.
Le but principal de la présente invention est
celui d'éliminer les précités inconvénients.
Les documents US-A-4 538 534, US-A-3 900 899 et FR-E 95 588
décrivent des procédés pour le traitement de produits manufacturés tubulaires.
A ce résultat on est parvenu, conformément à
l'invention, en adoptant
un dispositif ayant les caractéristiques décrites
dans la partie caractérisante de la revendication 1.
D'autres caractéristiques font l'objet des
revendications dépendantes.It is also known that in certain cases it is required to carry out, in a separate operational station, a longitudinal section of said manufactured products, on the side opposite to that of the point, along a section of predetermined length, to allow the 'coupling by means of a seam made by hand in correspondence with the edges of the stockings thus cut, so as to obtain a pantyhose. Said cut and said seam of union of the two stockings must be suitably oriented according to a local reference point, such as for example a predetermined direction relative to the seam line of each point to guarantee the adaptation of the garment.
All of this involves an excessively long production time in relation to current production requirements and requires the use of means and personnel specifically responsible for cutting and replacing manufactured products outside the spike sewing machine.
The main object of the present invention is to eliminate the aforementioned drawbacks.
Documents US-A-4,538,534, US-A-3,900,899 and FR-E 95,588 describe methods for the treatment of tubular manufactured products. This result has been achieved, in accordance with the invention, by adopting a device having the characteristics described in the characterizing part of claim 1. Other characteristics are the subject of the dependent claims.
Les avantages qui dérivent de la présente invention consistent essentiellement en ce que il est possible obtenir une forte réduction du temps et du coût de fabrication, outre à une forte simplification de la procedure d'ensemble de traitement des produits manufacturés étant éliminée la phase de réplacement des mêmes après la couture des pointes; qu'il est possible mettre une marque sur le tissu pour singaler la zone d'insertion d'un eventuel gousset périnéal; qu'un dispositif conformément à l'invention est de fabrication simple, économique et fiable même après un temps prolongé d'utilisation.The advantages which derive from the present invention basically consist of what it is possible get a big reduction in time and manufacturing cost, in addition to a high simplification of the overall procedure of processing of manufactured goods being eliminated the replacement phase of the same after sewing points; that it is possible to put a mark on the fabric to mark the insertion area of a possible perineal gusset; that a device according to the invention is manufacturing simple, economical and reliable even after a while extended use.
Ces avantages et caractéristiques de l'invention ainsi que d'autres seront plus et mieux compris de chaque homme du métier à la lumière de la description qui va suivre et à l'aide des dessins annexés donnés à titre d'exemplification pratique d'une forme concrète de réalisation, mais à ne pas considérer dans le sens limitatif, sur lesquels: la fig. 1 représente schématiquement un dispositif conformément à l'invention, en position de coupe d'un produit manufacturé tubulaire investi sur un tube renverseur respectif de support; la fig. 2 représente schématiquement une vue en plan du dispositif de la fig. 1; la fig. 3 représente schématiquement une vue de derrière du dispositif de la fig. 2.These advantages and characteristics of the invention as well as others will be more and better understood of each skilled person in light of the description which follows and using the drawings attached given as a practical example of a concrete form of realization, but not to consider in the limiting sense, on which: fig. 1 schematically represents a device according to the invention, in the cutting position of a tubular manufactured product invested in a respective support reversing tube; fig. 2 schematically represents a plan view of the device of fig. 1; fig. 3 represents schematically a rear view of the device of fig. 2.
Réduit à sa structure essentielle et en reférence aux figures des dessins annexés, un procédè pour le traitement de produits manufacturés tubulaires avec les deux extrémités ouvertes, comme bas pour collant, conformément à l'invention comprend les phases de charger chaque produit manufacturé, un par un, sur un tube correspondant renverseur pneumatique de support dans une machine à coudre les pointes, de renverser ledit produit manufacturé sur le tube de support respectif et le placer en position de couture de la pointe, d'en coudre la pointe selon une ligne de couture orientée selon une position prédéterminée et de décharger le produit manufacturé avec la pointe ainsi coussue, où est prevu de réaliser sur le produit manufacturé supporté par le tube respectif, une coupe de longueur prédéterminée selon une direction parallèle à son axe longitudinal, en amont de la station de déchargement du produit manufacturé, dans la même machine.Reduced to its essential structure and referenced in the figures of the appended drawings, a process for the processing of tubular manufactured products with both ends open, like bottom for sticky, according to the invention includes phases of loading each manufactured product, a by one, on a corresponding reversing tube support tire in a sewing machine spikes, to spill said manufactured product on the respective support tube and place it in sewing position of the tip, sew the point along a seam line oriented along a predetermined position and unload the manufactured product with the point thus sewn, where is planned to perform on the manufactured product supported by the respective tube, a cut of predetermined length in one direction parallel to its longitudinal axis, upstream of the unloading station for the manufactured product, in the same machine.
Avantageusement, conformément à l'invention, il est
prevu de réaliser ladite coupe longitudinale du
produit manufacturé dans une station successive à
celle de couture de la pointe.
En alternative, ladite coupe peut être réalisée en
amont de la station de couture de la pointe.
Il est aussi avantageusement prevu de mettre une
marque, en forme de n'importe quel signe apte, au
tissu du produit manufacturé placé en position de
coupe longitudinale, pour permettre l'application
successive d'un gousset périnéal dans une station
opérationnelle séparée.Advantageously, in accordance with the invention, it is planned to make said longitudinal cut of the manufactured product in a station successive to that of stitching the tip.
As an alternative, said cutting can be carried out upstream of the point sewing station.
It is also advantageously provided to put a mark, in the form of any suitable sign, on the fabric of the manufactured product placed in the longitudinal cutting position, to allow the successive application of a perineal gusset in a separate operational station.
Pour ce qui concerne le dispositif de réalisation du précité procédé opérationnel, ce-ci comprend une structure de base (1) fixe, c'est-à-dire solidaire à part fixe de la machine à coudre les pointes (2), laquelle est placée en amont de la station de déchargement des produits manufacturés de ladite machine (2) et présente deux tiges (3) parallèles entre elles et développées parallèlement aux tubes (4) de support des produits manufacturés (5), de manière à constituer un corps de guidage pour un chariot (6) pourvu de moyens de coupe avec un groupe ou unité lame - contrelame (7) et obtenir, au moyen du mouvement du chariot (6) le long de la direction des tiges de guidage (3), la coupe longitudinale du produit manufacturé (5) investi sur un tube (4) placé en correspondance de la structure (1), le long d'une section de longueur prédéterminée et correspondante à la course du chariot (6).Regarding the implementation device of the aforementioned operational process, this includes a fixed base structure (1), that is to say integral apart from the sewing machine (2), which is placed upstream of the unloading of manufactured goods from said machine (2) and has two parallel rods (3) between them and developed parallel to the tubes (4) to support manufactured products (5), so as to constitute a guide body for a carriage (6) provided with cutting means with a group or unit blade - counterblade (7) and obtain, by means of the movement of the carriage (6) along the direction of the guide rods (3), cutting longitudinal of the manufactured product (5) invested on a tube (4) placed in correspondence with the structure (1), along a length section predetermined and corresponding to the course of the carriage (6).
Avantageusemnet, conformément à l'invention, ledit
chariot (6) est asservi à des moyens de mouvement
correspondants comprenants un cylindre opérationnel
(60) à double effet, de manière à en permettre la
course selon l'axe respectif, dans les deux sens.
En outre, avantageusement, ledit group lame-contrelame
(7) est monté oscillant autour à l'axe
(e-e) d'un pivot excentrique (8) porté par ledit
chariot (6), à commande d'un cylindre réalisateur
(9) correspondant lequel est supporté par le
chariot même. De cette façon, la lame (7) est
placée en position de coupe du produit manufacturé
(5) lorsque le tube relatif (4) est dans la station
de coupe, c'est-à-dire en correspondance de la
structure (1), et en position de repos lorsque le
tube est acheminé à la station successive de la
machine (2), à la fin de l'opération de coupe.
Ledit pivot (8) est avantageusement monté tournant
autour à l'axe longitudinal respectif (e-e) et
partiellement appuié sur un guide rectiligne fixe
(80) solidaire à la structure de base (1), de
manière que l'unité (7) résulte montée en bosselage
sur le guide (80) et que le glissement du chariot
(6) résulte facilité.Advantageously, in accordance with the invention, said carriage (6) is slaved to corresponding movement means comprising an operational cylinder (60) with double effect, so as to allow it to travel along the respective axis, in both directions.
In addition, advantageously, said blade-counterblade group (7) is mounted oscillating around the axis (ee) of an eccentric pivot (8) carried by said carriage (6), controlled by a producing cylinder (9). which is supported by the cart itself. In this way, the blade (7) is placed in the position for cutting the manufactured product (5) when the relative tube (4) is in the cutting station, that is to say in correspondence with the structure (1). , and in the rest position when the tube is routed to the successive station of the machine (2), at the end of the cutting operation.
Said pivot (8) is advantageously mounted rotating around the respective longitudinal axis (ee) and partially supported on a fixed rectilinear guide (80) integral with the base structure (1), so that the unit (7) results embossed on the guide (80) and that the sliding of the carriage (6) results facilitated.
La structure fonctionnelle d'une machine à coudre le pointe, comme celle des moyens de commande et contrôle respectifs, sont en soi dejà connus par les hommes du métier et pour ce-ci ne sont pas décrits ici avec d'autres détails. Les brevets EP 33039 et US 4192242 décrivent des machines pour coudre les pointes des bas.The functional structure of a sewing machine the tip, like that of the control means and respective control, are in themselves already known by those skilled in the art and for this one are not described here with further details. EP patents 33039 and US 4192242 describe machines for sew the ends of the stockings.
Le functionnement du dispositif décrit est le
suivant. Quand le produit manufacturé (5) avec le
tube respectif (4) de support arrive en
correspondance de la structure (1), provenant par
exemple de la station de couture de la pointe, le
cylindre (9) est activé qui ainsi détermine la
rotation de l'unité (7) autour à l'axe du pivot
(8), de manière à la placer en position de coupe.
Ensuite, est activé le cylindre (60) qui détermine
le mouvement du chariot (6) avec l'unité de coupe
(7) ainsi placée, pour une course de longueur
correspondante à celle de la coupe voulue obtenir.
A la fin de la course du chariot (6) - laquelle est
peut être contrôlée de façon mécanique avec
l'emploi d'un fin de course ou électroniquement en
utilisant des moyens optiques en soi déjà connus -
le cylindre (9) commande la rotation inversée de
l'unité (7) et le cylindre (60) ramène le chariot
(6) dans sa position initiale. Successivement, le
tube (4) avec le produit manufacturé ainsi traité
est acheminé vers la station de déchargement de la
machine (2).
Pour réaliser ladite coupe longitudinale du produit
manufacturé (5) il n'est pas neccessaire de
réplacer ce dernier par rapport à un point de
repère local, comme par contre il advient dans le
cas des techniques conventionnelles.
Il va de soi, en outre, que pour réaliser ladite
coupe peuvent être adoptés des moyens capables
d'effectuer une function équivalente à celle de
l'unité en lame (7). Par exemple, au lieu de la
lame (7) peut être prevue une résistance
électrique, pour simplification ne pas repprésentée
dans les figures des dessins annexés, montée de la
même façon sur le chariot (6).The function of the device described is as follows. When the manufactured product (5) with the respective support tube (4) arrives in correspondence with the structure (1), coming for example from the tip sewing station, the cylinder (9) is activated which thus determines the rotation of the unit (7) around the axis of the pivot (8), so as to place it in the cutting position. Then activated the cylinder (60) which determines the movement of the carriage (6) with the cutting unit (7) thus placed, for a stroke of length corresponding to that of the desired cut. At the end of the carriage stroke (6) - which can be controlled mechanically with the use of a limit switch or electronically using optical means per se already known - the cylinder (9) controls the rotation reversed from the unit (7) and the cylinder (60) returns the carriage (6) to its initial position. Subsequently, the tube (4) with the manufactured product thus treated is sent to the unloading station of the machine (2).
To make said longitudinal cut of the manufactured product (5), it is not necessary to replace the latter with respect to a local benchmark, as, on the other hand, it happens in the case of conventional techniques.
It goes without saying, moreover, that for making said cut can be adopted means capable of performing a function equivalent to that of the blade unit (7). For example, instead of the blade (7) can be provided an electrical resistance, for simplicity not shown in the figures of the accompanying drawings, mounted in the same way on the carriage (6).
