Abstract

The invention relates to a device enabling thin flexible sheets to be introduced between two rollers which are intended to fold them. This device consists of a bar r with blow jets supplied with compressed fluid via a remote-control valve v of a control device i opening and closing the valve at the desired moment. The device according to the invention is particularly intended for folding pancakes.

Description

Dispositif séquentiel destiné à plier tout objet mince et souple de forme géométrique définie. Sequential device for folding any thin and flexible object of defined geometric shape.

La présente invention concerne--un dispositif séquentiel destiné à plier une ou plusieurs fois des objets minces et soupies et plus généralement ayant une faible tenue mécanique,de forme géométrique définie,notemment,decrêpes,des feuilles de papier,de pla tique,e.t.c.  The present invention relates to - a sequential device intended to fold one or more times thin and soupy objects and more generally having a low mechanical strength, of defined geometric shape, notably, pancakes, sheets of paper, plastics, etc.

Le pliage de ces objets,est généralement effectué par des moyens mécaniques,qui présentent l'inconvénient de nécessiter pour fonctionner correctement,une homogénéité parfaite dans le temps et dans l'espace des caractéristiques mécaniques des objets à plier,ces conditions étant difficilement réalisables dans la pratique.La presente invention remédie à cet inconvénient. The folding of these objects is generally carried out by mechanical means, which have the drawback of requiring, in order to function correctly, perfect homogeneity over time and in space of the mechanical characteristics of the objects to be folded, these conditions being difficult to achieve in The present invention overcomes this drawback.

Le dispositif utilisé,comprend une commande actionnée par l'objet à plier.Cette commande,peut être unlinterrupteur électrique,pneumatique,hydraulique à commande mécanique,optique, pneumatique,hydraulique ou tout autre.Cette commande,envoie un signal qui ouvre une vanne.Le circuit ainsi auvert,alimente en fluide sous pression une rampe de distribution qui envoie un ou plusieurs jets de forme et de direction appropriées qui pousse l'objet à plier entre deux cylindres qui entrainent l'objet plié.Lorsque ltobjet à plier n'actionne plus le dispositif de commande,la vanne se ferme et coupe le circuit de fluide comprimé et le dispositif est pret pour une nouvelle opération. The device used includes a command actuated by the object to be bent. This command can be an electrical, pneumatic, hydraulic switch with mechanical, optical, pneumatic, hydraulic or any other command. This command sends a signal which opens a valve. The circuit thus open, supplies pressurized fluid to a distribution manifold which sends one or more jets of suitable shape and direction which pushes the object to bend between two cylinders which drive the folded object. When the object to be folded does not operate plus the control device, the valve closes and cuts off the compressed fluid circuit and the device is ready for a new operation.

Sur une même machine,le dispositif peut être installé plusieurs fois dans différentes positions,afin de plier de façon divers les objets.On the same machine, the device can be installed several times in different positions, in order to bend objects in different ways.

A titre d'exemple non limitatif, le dispositif est utilisé dans une machine effectuant le pliage des crêpes fabriquées industriellement. By way of nonlimiting example, the device is used in a machine performing the folding of industrially manufactured pancakes.

La crêpe provenant des plaques de cuisson et du traitement destiné à lui donner la consistance voulue,est acheminée sur un transporteur "a",stengage dans une fente b" selon la figure ;,payse devant les deux cylindres destinés au pliage, descend d'une longueur égale au demi diamétre de la crêpe ( figure2) elle actionne alors le levier de commande d'un inirupteur "it' qui ouvre une électrovanne à air comprimé "v" qui souffle dans une rampe de distribution "r" qui pousse la crêpe entre les deux rouleaux plieurs "c" (figure 3).quand la crêpe est prise par les rouleaux "c",son bord inférieur remonte,et relache la commande de l'interrupteur "i",l'électrovanne "v" se ferme et coupe 1' arrivée d'air (figure 4).La crêpe pliéeen deux est entrainnée par un autre transporteur"a"' (figure 1) et commande un autre interrupteur "i"' semblable au minirupteur "i" commandant une deuxiéme électrovanne "v"' (figure 2).Cette électrovanne ouvre un deuxiéme circuit d'air comprimé qui alimente une rampe 'Zrin qui envoie des jets d'air de telle maniére qu'ils poussent la crêpe entre deux autres cylindres "c"' qui effectuent un autre pliage à angle droit du premier (figures 3 et 4).La crêpe se trouve alors pliée en quatre,ce qui est la présentation habituelle de ce produit.Une variente du procédé,consiste à faire effectuer sur un transporteur intermédiaire 1/4 de tour à la crêpe,et d'effectuer le deuxiéme pliage de la même maniére que le premier.  The pancake from the cooking plates and the treatment intended to give it the desired consistency, is conveyed on a conveyor "a", stengage in a slot b "according to the figure;, paid in front of the two cylinders intended for folding, descends from a length equal to half the diameter of the pancake (figure2) it then actuates the control lever of an inirupteur "it" which opens a compressed air solenoid valve "v" which blows in a distribution ramp "r" which pushes the pancake between the two folding rollers "c" (figure 3). when the pancake is taken up by the rollers "c", its lower edge rises, and releases the control of the switch "i", the solenoid valve "v" closes and cuts the air supply (figure 4). The pancake folded in half is driven by another conveyor "a" '(figure 1) and controls another switch "i" "similar to the microswitch" i "controlling a second solenoid valve "v" '(figure 2). This solenoid valve opens a second compressed air circuit which feeds a' Zri ramp n which sends air jets in such a way that they push the pancake between two other cylinders "c" 'which perform another folding at right angles to the first (Figures 3 and 4). The pancake is then folded in four , which is the usual presentation of this product. One variation of the process, consists in having an intermediate conveyor perform 1/4 turn with the pancake, and performing the second folding in the same way as the first.
