Description

La présente invention à pour objet un dispositif pour aligner des découpes de boîtes dans une machine les travaillant notamment dans une plieuse-colleuse.The present invention relates to a device for aligning cutouts of boxes in a machine working in particular in a folder-gluer.

Les plieuses-colleuses que l'on connaît à ce jour sont des machines dans lesquelles on prend les découpes de boîtes, une à une du dessous d'une pile, et qu'on transporte ensuite aux différentes sections de la machine à l'aide de convoyeurs à courroie, pour les recevoir, en fin de processus, "pliées à plat" et collées dans une station terminale. Il est bien entendu que la découpe de boîte va subir plusieurs opérations successives qui s'effectuent tout au long de son déplacement en machine. Par ordre chronologique, ces opérations sont les suivantes :

  • Dans une première section, précassage du premier et troisième plis de la découpe avec réouverture de celle-ci de façon à la présenter "à plat" dans une deuxième section,
  • La section d'encollage d'où la découpe sera acheminée vers une troisième section,
  • La section de pliage, dans laquelle la découpe sera pliée le long de son deuxième et quatrième plis.
  • La découpe sera ensuite transportée dans une cinquième section de pressage et d'éjection à la sortie de laquelle, chaque découpe, pliée, sera empilée sur l'entrée d'une sixième section, le section de réception.
The folder-gluers that we know today are machines in which we take the box cutouts, one by one from the bottom of a pile, and then transport them to the different sections of the machine using belt conveyors, to receive them, at the end of the process, "folded flat" and glued in a terminal station. It is understood that the box cutting will undergo several successive operations which are carried out throughout its movement in the machine. In chronological order, these operations are as follows:
  • In a first section, pre-crushing of the first and third folds of the cut with reopening of the latter so as to present it "flat" in a second section,
  • The gluing section from where the cut will be routed to a third section,
  • The folding section, in which the cutout will be folded along its second and fourth folds.
  • The cut will then be transported in a fifth pressing and ejection section at the exit of which, each folded cut, will be stacked on the entry of a sixth section, the receiving section.

Afin d'obtenir un pliage précis suivant chacune des ligne de pliage, il est nécessaire que le transport des découpes de boîtes au travers de la machine s'effectue sans glissement, tant latéral que longitudinal. A cet effet, on utilise en combinaison des transporteurs à courroie inférieurs et supérieurs ainsi que, dans certains cas, la combinaison d'un ou plusieurs transporteurs inférieurs à courroie avec des rampes supérieures de galets presseurs.In order to obtain a precise folding along each folding line, it is necessary that the transport of the box blanks through the machine is carried out without sliding, both lateral and longitudinal. For this purpose, lower and upper belt conveyors are used in combination as well as, in some cases, the combination of one or more lower belt conveyors with upper ramps of pressure rollers.

L'un des problèmes importants rencontré dans les plieuses-colleuses réside dans le fait de l'imprécision fonctionnelle des dispositifs d'introduction des découpes dans la machine. Ces dispositifs d'introduction se composent généralement d'un transporteur inférieur à courroies multiples, associé, d'une part, à une jauge frontale laissant, entre les courroies des transporteurs, un espace suffisant pour ne laisser passer qu'une découpe à la fois et, d'autre part, à des joues latérales, réglables en fonction du format des découpes à introduire. L'alimentation séquentielle des découpes peut être obtenue à l'aide d'organes agissant de façon à obturer, partiellement et momentanément, l'espace existant entre les courroies des transporteurs et l'extrémité inférieure de la jauge frontale, empêchant de ce fait le départ de la découpe inférieure de la pile de découpes placées sur le dispositif d'introduction. L'entraînement de la découpe à introduire s'explique donc par le fait que l'adhérence entre sa face inférieure et les courroies des transporteurs est beaucoup plus importante que le frottement de sa face supérieure contre la découpe suivante de la pile.One of the major problems encountered in folder-gluers lies in the fact that the devices for inserting the blanks into the machine are imprecise. These introduction devices generally consist of a lower conveyor with multiple belts, associated, on the one hand, with a front gauge leaving, between the conveyor belts, sufficient space to allow only one cut to pass at a time. and, on the other hand, to side cheeks, adjustable according to the format of the cuts to be introduced. The sequential feeding of the blanks can be obtained by means of members acting so as to close, partially and momentarily, the space existing between the conveyor belts and the lower end of the front gauge, thereby preventing the start of the lower cutout from the stack of cutouts placed on the introducer. The drive of the cut to be introduced is therefore explained by the fact that the adhesion between its lower face and the conveyor belts is much greater than the friction of its upper face against the next cut of the stack.

Cependant, en raison même de cette adhérence et de ce frottement, il se peut que, dans certains cas, l'entraînement de la découpe ne soit pas uniforme à tous les endroits de celle-ci. L'encrassement des courroies peut provoquer cette différence d'adhérence, ce qui a pour effet que la découpe est introduite de travers dans la machine, rendant, de ce fait, très aléatoire son pliage subséquent suivant les lignes de pliage imposées.However, due to this very adhesion and friction, it may be that, in certain cases, the drive of the cutout is not uniform at all places thereof. The fouling of the belts can cause this difference in adhesion, which has the effect that the cutout is introduced at an angle in the machine, thereby making its subsequent folding very random along the imposed folding lines.

Des dispositifs de correction de ce mauvais alignement des découpes existent déjà. On les place, de préférence, dans une section située juste après le dispositif d'introduction. Dans certains cas, on choisit de les substituer à la première section de précassage des plis. L'un des dispositifs de correction d'alignement connus de la pratique consiste en un rectificateur comprenant une série de rouleaux inférieurs et supérieurs disposés en quinconce sur une poutrelle inférieure et une poutrelle supérieure que l'on peut éloigner, l'une de l'autre, de façon à tenir compte de l'épaisseur de la découpe passant entre les rouleaux supérieurs et inférieurs. Le dispositif permettant d'éloigner les poutrelles l'une de l'autre comporte, en outre, un dispositif assurant une pression permanente et variable des rouleaux supérieurs sur la face supérieure de la découpe. Les poutrelles supérieure et inférieure sont, d'autre part, agencées de façon à pouvoir être disposées suivant un angle défini et invariable par rapport à l'axe longitudinal de la machine.Devices for correcting this poor alignment of the cuts already exist. They are preferably placed in a section located just after the introducer. In some cases, we choose to substitute them for the first crease pre-crushing section. One of the alignment correction devices known in the art consists of a rectifier comprising a series of lower and upper rollers staggered on a lower beam and an upper beam which can be moved away, one of the other, so as to take into account the thickness of the cutout passing between the upper and lower rollers. The device making it possible to move the beams apart from one another further comprises a device ensuring permanent and variable pressure of the upper rollers on the upper face of the blank. The upper and lower beams are, on the other hand, arranged so that they can be arranged at a defined and invariable angle relative to the longitudinal axis of the machine.

L'ensemble ainsi constitué agit conjointement avec un rail longitudinal de guidage. De ce fait, en choisissant une inclinaison correcte du rectificateur, l'action des rouleaux de celui-ci, sur l'un des côtés de chacune des découpes, va appliquer leur tranche contre le rail longitudinal de guidage et provoquera, au cours du déplacement des découpes, l'équerrage de chacune d'entre elles, ce qui aura pour effet de placer les découpes dans une position telle que leurs lignes de pliage respectives seront parfaitement parallèles à l'axe longitudinal de la machine.The assembly thus formed acts jointly with a longitudinal guide rail. Therefore, by choosing a correct inclination of the rectifier, the action of the rollers thereof, on one of the sides of each of the cuts, will apply their edge against the longitudinal guide rail and will cause, during the movement of the cuts, the squareness of each of them , which will have the effect of placing the blanks in a position such that their respective fold lines will be perfectly parallel to the longitudinal axis of the machine.

Les rouleaux de chacune des poutrelles supérieure et inférieure sont entraînés au moyen d'une courroie plate transmettant son mouvement auxdits rouleaux par l'intermédiaire de poulies montées sur les axes de chacun des rouleaux des poutrelles supérieure et inférieure. La disposition en quinconce des rouleaux autorise, de ce fait, un déplacement vertical de la poutrelle supérieure, de façon à pouvoir tenir compte de l'épaisseur des découpes à travailler, sans pour autant pincer la courroie d'entraînement entre deux poulies, ce qui serait le cas si la disposition en quinconce n'était pas choisie.The rollers of each of the upper and lower beams are driven by means of a flat belt transmitting its movement to said rollers by means of pulleys mounted on the axes of each of the rollers of the upper and lower beams. The staggered arrangement of the rollers allows, therefore, a vertical displacement of the upper beam, so as to be able to take into account the thickness of the cuts to be worked, without pinching the drive belt between two pulleys, which would be the case if the staggered arrangement was not chosen.

La solution qui consiste à placer les rouleaux du rectificateur sur des poutrelles supérieure et inférieure, inclinées par rapport à l'axe longitudinal de la machine, implique de ménager, à l'entrée du rectificateur, un jeu d'environ 2 millimètres entre le bord de la découpe et le rail longitudinal de guidage, de façon à ce qu'à la sortie du rectificateur, le bord de la découpe soit appliqué contre le rail longitudinal et que, par conséquent, les lignes de pliage des découpes successives se trouvent toujours à la même position par rapport aux organes de pliage ultérieurs. On crée ainsi un effet "d'entonnoir" qui, dans certains cas, applique trop fortement le bord de la découpe contre le rail longitudinal de guidage et provoque sa détérioration. D'autre part, le jeu laissé à l'entrée du rectificateur entre le bord de la découpe et le rail longitudinal de guidage demande un ajustement transversal précis du rectificateur par rapport aux organes d'introduction et, comme ce jeu peut être variable en fonction de la qualité des découpes à travailler, il est nécessaire de procéder manuellement à ce réglage excluant, par là, toute automatisation du réglage latéral des différents organes de la machine. Un autre inconvénient de ce type de rectificateurs réside dans le fait que l'action sur la découpe, par les rouleaux supérieurs, s'effectue entre les rouleaux inférieurs et non dans leur axe vertical ce qui, en cas de pression excessive nécessitée par une découpe très lisse et glissante, par exemple une découpe recouverte d'une impression sur l'une de ses faces et d'une enduction d'étanchéité sur l'autre, va provoquer une ondulation de la découpe, peut-être légère, mais suffisante pour empêcher son équerrage ou, tout au moins, pour perturber cette opération. De plus, ce genre de rectificateur doit être retiré de la machine dans le cas où les découpes de boîtes travaillées n'autorisent pas son utilisation. Il en résulte une grande perte de temps en démontage et en transformation de la section de la plieuse-colleuse concernée.The solution which consists in placing the rollers of the rectifier on upper and lower beams, inclined with respect to the longitudinal axis of the machine, involves providing, at the entrance of the rectifier, a clearance of approximately 2 millimeters between the edge of the cutout and the longitudinal guide rail, so that at the outlet of the rectifier, the edge of the cutout is applied against the longitudinal rail and, therefore, the fold lines of the successive cutouts are always at the same position relative to the subsequent folding members. This creates a "funnel" effect which, in some cases, applies the edge of the cut too strongly against the longitudinal guide rail and causes its deterioration. On the other hand, the clearance left at the entrance of the rectifier between the edge of the cutout and the longitudinal guide rail requires precise transverse adjustment of the rectifier with respect to the insertion members and, as this clearance can be variable depending on of the quality of the cuts to be worked, it is necessary to make this adjustment manually, thereby excluding any automation of the lateral adjustment of the various parts of the machine. Another disadvantage of this type of rectifier lies in the fact that the action on the cut, by the upper rollers, takes place between the lower rollers and not in their vertical axis which, in the event of excessive pressure required by a cut very smooth and slippery, for example a cut covered with a print on one of its faces and a sealing coating on the other, will cause an undulation of the cut, perhaps slight, but sufficient for prevent its squaring or, at least, to disrupt this operation. In addition, this kind of rectifier must be removed from the machine in the event that the cutouts of the worked boxes do not allow its use. This results in a great loss of time in disassembly and transformation of the section of the folder-gluer concerned.

Le but de la présente invention consiste à fournir un dispositif pour aligner des découpes de boîtes, qui supprime les inconvénients précités, améliore les temps utilisés pour le réglage des organes successifs de la plieuse-colleuse et autorise son automatisation optimale.The object of the present invention is to provide a device for aligning box cutouts, which eliminates the aforementioned drawbacks, improves the times used for the adjustment of the successive members of the folder-gluer and allows its optimal automation.

A cet effet, la présente invention est définie en conformité avec ce qu'énonce la revendication 1.To this end, the present invention is defined in accordance with what is stated in claim 1.

Le dispositif pour aligner des découpes de boîtes représenté sur la figure 1 comporte un organe de rectification supérieur 1 et un organe de rectification inférieur 2. L'organe de rectification supérieur 1 comporte un longeron fixe 3 relié à une potence 4 [voir fig. 2] de la plieuse-colleuse à l'aide de deux étriers 5 fixés, à l'une de leurs extrémités, au moyen des vis six pans 7, dans la partie inférieure d'une tige de réglage 6 maintenue dans un support 8 monté à l'aide des vis 9 contre l'une des faces de la potence 4 [voir figures 2 et 3]. L'étrier 5 est fixé, à son autre extrémité, contre l'une des faces latérales du longeron fixe 3 au moyen des vis 10. Le blocage de la tige de réglage 6 est obtenu à l'aide d'un plot 11 ayant une largeur sensiblement plus faible que celle du support 8 permettant, lors du serrage des vis 12, de provoquer le blocage vertical de la tige de réglage dans une position désirée [voir aussi figures 2 et 3]. Le longeron fixe 3 comporte une série d'alésages 13 dans lesquels sont chassées des douilles 14, de préférence autolubrifiantes, destinées à recevoir un tourrillon 15 servant de point de pivotement pour les supports 16 des leviers pivotants 17. Le longeron fixe 3 comporte aussi des perçages 18 au travers desquels passent les tiges de guidage 19 des ressorts 20. Ces tiges de guidage 19 sont fixées, à l'une de leurs extrémités, dans une rampe 21 à l'aide d'une goupille élastique 22 [voir aussi figure 4]. A leur autre extrémité, chacune des tiges de guidage 19 possède une portée 23 sur laquelle est guidée la partie supérieure du ressort 20 alors que sa partie inférieure prend appui dans une fraisure 24 aménagée dans le levier pivotant 17. La rampe 21 est assujettie, par ses extrémités, au longeron fixe 3 au moyen d'une tige filetée de réglage 25 vissée à l'une de ses extrémités dans le longeron fixe 3, alors que son autre extrémité est pourvue de deux poulets moletés 26 destinés à assurer le réglage de la pression des organes de rectification supérieurs 1 sur la découpe de boîte. A cet effet, on a prévu de monter, autour de la tige filetée de réglage 25 et entre le longeron fixe 3 et la rampe 21, un ressort de compression 27. Ce ressort de compression 27 est guidé dans un alésage 28 usiné dans la face inférieure de la rampe 21. Ainsi, suivant que l'on visse ou dévisse le premier poulet moleté 26, on augmente ou libère la pression des organes de rectification supérieurs 1 sur la découpe de boîte, ladite pression étant de ce fait assurée, d'une part, par les ressorts 20 et, d'autre part, par les ressorts de compression 27.The device for aligning box cutouts shown in FIG. 1 comprises an upper rectification member 1 and a lower rectification member 2. The upper rectification member 1 comprises a fixed spar 3 connected to a bracket 4 [see fig. 2] of the folder-gluer using two stirrups 5 fixed, at one of their ends, by means of the hexagon screws 7, in the lower part of an adjustment rod 6 held in a support 8 mounted using the screws 9 against one of the faces of the bracket 4 [see Figures 2 and 3]. The stirrup 5 is fixed, at its other end, against one of the lateral faces of the fixed spar 3 by means of the screws 10. The locking of the adjustment rod 6 is obtained using a stud 11 having a width substantially smaller than that of the support 8 allowing, when tightening the screws 12, to cause the vertical locking of the adjustment rod in a desired position [see also Figures 2 and 3]. The fixed spar 3 comprises a series of bores 13 in which bushings 14, preferably self-lubricating, are driven, intended to receive a swivel 15 serving as a pivot point for the supports 16 of the pivoting levers 17. The fixed spar 3 also includes holes 18 through which the guide rods 19 of the springs 20 pass. These guide rods 19 are fixed, at one of their ends, in a ramp 21 using an elastic pin 22 [see also FIG. 4 ]. At their other end, each of the guide rods 19 has a bearing surface 23 on which the upper part of the spring 20 is guided while its lower part is supported in a countersink 24 arranged in the pivoting lever 17. The ramp 21 is secured, by its ends to the fixed spar 3 by means of a threaded adjustment rod 25 screwed at one of its ends into the fixed spar 3, while its other end is provided with two knurled chickens 26 intended to adjust the pressure of the upper rectifying members 1 on the box cutout. To this end, provision has been made to mount, around the adjusting threaded rod 25 and between the fixed spar 3 and the ramp 21, a spring of compression 27. This compression spring 27 is guided in a bore 28 machined in the underside of the ramp 21. Thus, depending on whether the first knurled chicken 26 is screwed or unscrewed, the pressure of the rectifying members is increased or released upper 1 on the box cutout, said pressure being therefore ensured, on the one hand, by the springs 20 and, on the other hand, by the compression springs 27.

Les leviers pivotants 17 sont portés par un axe 29 situé dans le support 16, de façon à ce que leur pivotement intervienne dans un plan vertical. Cet axe 29 est constitué par une douille filetée 30 maintenue, dans le support 16, à l'aide d'une vis 31 vissée à l'une de ses extrémités et par une organe flexible 32 vissé à son autre extrémité. L'organe flexible 32 est constitué, de préférence, par un cylindre de caoutchouc 33 auquel on a fixé, d'une part, une tige filetée 34 et, d'autre part, une bague filetée 35. L'extrémité inférieure du levier pivotant 17 est équipée d'un galet 36 constitué par un roulement à billes fixé, au levier, au moyen d'une vis 37 et d'un écrou 38. Afin d'améliorer l'adhérence du galet 36 sur la découpe, on pourrait aisément imaginer de le recouvrir d'un matériau tel que du caoutchouc.The pivoting levers 17 are carried by an axis 29 located in the support 16, so that their pivoting occurs in a vertical plane. This axis 29 is constituted by a threaded sleeve 30 held in the support 16, using a screw 31 screwed at one of its ends and by a flexible member 32 screwed at its other end. The flexible member 32 is preferably made up of a rubber cylinder 33 to which a threaded rod 34 is attached, on the one hand, and a threaded ring 35, on the other hand. The lower end of the pivoting lever 17 is equipped with a roller 36 consisting of a ball bearing fixed to the lever by means of a screw 37 and a nut 38. In order to improve the adhesion of the roller 36 on the cutout, it could easily be imagine covering it with a material such as rubber.

Le support 16 est, d'autre part, agencé de façon à laisser un passage 39 pour le ressort 20. Ce passage 39 est en fait un perçage d'un diamètre suffisamment grand pour que ses parois ne touchent pas le ressort lors du pivotement dans le plan horizontal du support 16.The support 16 is, on the other hand, arranged so as to leave a passage 39 for the spring 20. This passage 39 is in fact a bore of a diameter large enough so that its walls do not touch the spring during pivoting in the horizontal plane of the support 16.

Chaque organe flexible 32, vissé à l'extrémité de la douille filetée 30, est relié à une cornière 40 déplaçable, dans un plan horizontal par rapport au longeron fixe 3, par une, vis 66 s'engageant dans la bague filetée 35. Cette cornière 40 est munie de deux pattes 41 et 42 au travers desquelles passe une tige filetée 43, respectivement 44. Chacune de ces tiges filetées 43 et 44 est vissée au travers du longeron fixe 3 et assurée en position à l'aide d'un écrou 45, respectivement 46. Des poulets moletés 47 et 48 sont montés sur la tige filetée 43 ou 44, de façon à permettre le déplacement, dans le plan horizontal, de la cornière 40.Each flexible member 32, screwed to the end of the threaded sleeve 30, is connected to a movable angle iron 40, in a horizontal plane relative to the fixed spar 3, by a, screw 66 engaging in the threaded ring 35. This angle iron 40 is provided with two tabs 41 and 42 through which a threaded rod 43, respectively 44 passes. Each of these threaded rods 43 and 44 is screwed through the fixed spar 3 and secured in position using a nut 45, respectively 46. Knurled chickens 47 and 48 are mounted on the threaded rod 43 or 44, so as to allow the displacement, in the horizontal plane, of the angle iron 40.

Des rondelles 49 et 50 assurent un bon contact entre la patte 41 ou 42 et les poulets moletés 47 et 48. Un dispositif de transport 51, pivotant et réglable en pression, est prévu à l'entrée des organes de rectification supérieurs 1 et inférieurs 2. Ce dispositif, étant accessoire et destiné en fait à assurer le transport de la découpe des organes d'introduction au dispositif d'alignement, ne sera pas décrit plus en détail.Washers 49 and 50 ensure good contact between the tab 41 or 42 and the knurled chickens 47 and 48. A transport device 51, swivel and adjustable in pressure, is provided at the inlet of the upper 1 and lower 2 grinding members This device, being accessory and in fact intended to ensure the transport of the cutout of the introduction members to the alignment device, will not be described in more detail.

Les organes de rectification inférieurs 2 sont disposés dans l'alignement des organes de rectification supérieurs 1. Ils sont constitués par une courroie sans fin 52 entraînée, passant autour d'une poulie 53 et étant supportée par une série de galets 54 dont les axes sont alignés avec les axes des galets 36 des organes de rectification supérieurs 1. Ces galets 54 de support de la courroie sans fin 52 sont avantageusement réalisés en utilisant deux roulements à billes placés, côte à côte, entre deux joues latérales 55 et 56. L'une de ces deux joues latérales 55 ou 56 étant fixée au longeron inférieur 57 de la plieuse-colleuse à l'aide de vis 58.The lower rectifying members 2 are arranged in alignment with the upper rectifying members 1. They consist of an endless belt 52 driven, passing around a pulley 53 and being supported by a series of rollers 54 whose axes are aligned with the axes of the rollers 36 of the upper rectifying members 1. These rollers 54 for supporting the endless belt 52 are advantageously produced by using two ball bearings placed side by side between two side cheeks 55 and 56. One of these two side cheeks 55 or 56 being fixed to the lower spar 57 of the folder-gluer using screws 58.

La potence 4 est, d'autre part, fixée par l'intermédiaire d'un bras 59 audit longeron inférieur 57.The bracket 4 is, on the other hand, fixed by means of an arm 59 to said lower beam 57.

Les moyens d'alignement longitudinal 60 comprennent un rail longitudinal de guidage 61 soudé sur deux supports 62 aménagés de façon à ce que l'on puisse déplacer l'ensemble ainsi constitué dans un plan horizontal. Le blocage en position des moyens d'alignement longitudinal 60 est assuré par la vis 63 passant dans une fente 64 agencée dans les supports 62. Le serrage de la vis 63 permet de bloquer les moyens d'alignement longitudinal 60 sur les bras 59 supportant chacun une potence 4. Sur les figures 2 et 3, on a représenté, en traits mixtes, la course que peuvent effectuer les moyens d'alignement longitudinal 60.The longitudinal alignment means 60 comprise a longitudinal guide rail 61 welded to two supports 62 arranged so that the assembly thus formed can be moved in a horizontal plane. The longitudinal alignment means 60 are locked in position by the screw 63 passing through a slot 64 arranged in the supports 62. The tightening of the screw 63 makes it possible to block the longitudinal alignment means 60 on the arms 59 each supporting a bracket 4. In FIGS. 2 and 3, the stroke which the longitudinal alignment means 60 can perform is shown in dashed lines.

La figure 5 est une vue selon A de la figure 4 montrant l'un des éléments des organes de rectification supérieurs 1 en position neutre. Dans cette figure, le levier pivotant 17 et, par conséquent, le galet 36 sont dans une position parfaitement parallèle par rapport à l'axe longitudinal de la plieuse-colleuse, et les découpes se déplaçant dans le sens indiqué par la flèche 65 ne subiront aucun déplacement latéral. En d'autres termes, sans démontage et rien qu'en amenant la cornière 40 dans une position neutre, nous aurons transformé le dispositif pour aligner les découpes de boîte en un simple dispositif de transport de découpes.Figure 5 is a view along A of Figure 4 showing one of the elements of the upper rectifying members 1 in the neutral position. In this figure, the pivoting lever 17 and, consequently, the roller 36 are in a perfectly parallel position with respect to the longitudinal axis of the folder-gluer, and the cutouts moving in the direction indicated by the arrow 65 will not undergo no lateral displacement. In other words, without dismantling and just by bringing the angle iron 40 in a neutral position, we will have transformed the device for aligning the box blanks into a simple blank transport device.

La figure 6 est une vue selon A de la figure 4 montrant l'un des éléments des organes de rectification supérieurs 1 en position de travail, c'est-à-dire dans la position qu'il occupe lorsque l'on désire aligner les découpes de boîtes successives contre la face du rail longitudinal de guidage 61. Pour arriver à faire prendre une position inclinée, dans un sens ou dans l'autre, au levier pivotant 17, il suffit de déplacer, horizontalement, la cornière 40 à l'aide des poulets moletés 47 et 48 [voir fig. 2]. Ce déplacement fera pivoter le support 16 autour de son tourillon 15 et déformera l'organe flexible 32. Il sera donc possible de choisir très précisement l'angle que l'on désire donner au support 16 en fonction de la rectification à effectuer et de la qualité de la découpe de boîte à travailler. On contrôlera ainsi la force d'application des bords des découpes contre le rail longitudinal de guidage 61.FIG. 6 is a view along A of FIG. 4 showing one of the elements of the upper rectifying members 1 in the working position, that is to say in the position which it occupies when it is desired to align the successive box cuts against the face of the longitudinal guide rail 61. To achieve an inclined position, in one direction or the other, with the pivoting lever 17, it suffices to move, horizontally, the angle 40 using knurled chickens 47 and 48 [see fig. 2]. This movement will rotate the support 16 around its pin 15 and deform the flexible member 32. It will therefore be possible to very precisely choose the angle that one wishes to give to the support 16 depending on the correction to be made and quality of the box cut to work. This will control the force of application of the edges of the cutouts against the longitudinal guide rail 61.

Il est évident que si l'on désire automatiser le dispositif, on pourra aisément remplacer les poulets moletés 47 et 48 par une fourchette motorisée agissant sur les pattes 41 et 42 de la cornière 40.It is obvious that if it is desired to automate the device, it is easy to replace the knurled chickens 47 and 48 by a motorized fork acting on the legs 41 and 42 of the angle 40.

En raison de la possibilité de faire pivoter le support 16 indifféremment vers la gauche ou la droite par rapport au sens de défilement des découpes de boîtes, il est clair que, dans certaines conditions, par exemple lorsque l'on traite une découpe de faible largeur, on utilisera le dispositif d'alignement sans avoir à le démonter d'un côté de la plieuse-colleuse pour le remonter sur l'autre côté, cela pour bénéficier de la plus longue partie de la découpe pour l'opération d'alignement.Because of the possibility of pivoting the support 16 either to the left or to the right with respect to the direction of travel of the box blanks, it is clear that, under certain conditions, for example when treating a small width blank , we will use the alignment device without having to disassemble it on one side of the folder-gluer to reassemble it on the other side, this to benefit from the longest part of the cutout for the alignment operation.

Un dispositif, tel que celui que nous venons de décrire, présente ainsi l'avantage de réduire les temps de réglage de la plieuse-colleuse en cas de changement de travail, tout en pouvant être utilisé, indifféremment et sans démontage, comme rectificateur ou comme simple organe de transport de découpes de boîtes.A device such as that which we have just described thus has the advantage of reducing the adjustment times of the folder-gluer in the event of a change of work, while being able to be used, indifferently and without dismantling, as a rectifier or as simple transport device for box cutouts.
