Description

Machine à échancrer et rainer le carton ondulé pour la confection de caisses.Machine for scoring and creasing corrugated cardboard for making boxes.

L'invention a pour objet une machine capable d'échancrer et de rainer en vue de la confection de caisses des feuilles ou des plaques en carton préalablement découpées aux dimensions générales voulues, en séries de petites quantités.The subject of the invention is a machine capable of scoring and grooving for the preparation of boxes of sheets or cardboard plates previously cut to the desired general dimensions, in series of small quantities.

Il existe des machines importantes qui sont conçues pour préparer des feuilles échancrées et rainées en très grandes séries. Ces machines sont aptes à produire ces feuilles à une vitesse très élevée mais à une dimension déterminée. Leur réglage pour la confection de feuilles à d'autres dimensions demande beaucoup de temps, quand il est possible.There are large machines which are designed to prepare scalloped and grooved sheets in very large series. These machines are capable of producing these sheets at a very high speed but at a determined size. Adjusting them for making sheets of other sizes is time consuming, when possible.

L'invention ne se rapporte pas à ces machines qui sont utilisées par les transformateurs du carton ondulé qui vendent les feuilles préparées pour la confection de caisses ayant des dimensions normalisées.The invention does not relate to these machines which are used by the processors of corrugated cardboard which sell the sheets prepared for the manufacture of cases having standardized dimensions.

L'invention concerne une machine destinée aux utilisateurs des caisses et des boîtes en carton ondulé qui confectionnent eux-mêmes leurs caisses aux dimensions qui leur conviennent à partir de plaques en carton. Les machines de ce type doivent permettre un réglage rapide et simple d'adaptation à des caisses différentes dont les quantités nécessaires sont, à chaque fois, peu importantes.The invention relates to a machine for users of corrugated boxes and boxes which themselves make their boxes to the dimensions which suit them from cardboard plates. The machines of this type must allow a quick and simple adjustment of adaptation to different cases whose quantities required are, each time, insignificant.

L'état de la technique dans ce domaine est illustré par le brevet français n° 2 076 763 qui décrit une machine conçue pour la fabrication de petites séries de feuilles en carton échancrées et rainées. Cette machine comprend essentiellement une table de travail au-dessus de laquelle s'étend une traverse mobile en sens vertical animée de mouvements de montée et de descente. Cette traverse porte une pince à deux mors en regard d'une nervure prévue sur la table et un couteau mobile d'échancrage est disposé entre les mors de cette pince. Des moyens non décrits saisissent successivement chaque feuille a découper et à rainer et des moyens d'entraînement la déplacent le long de la table de travail. Le positionnement précis de la feuille est assuré par des butées échelonnées, réglables et éclipsables qui sont portées par un arbre longitudinal relié à l'arbre de commande des mouvements verticaux de la traverse.The state of the art in this area is illustrated by French Patent No. 2,076,763 which describes a machine designed for the manufacture of small series of scalloped and grooved cardboard sheets. This machine essentially comprises a work table above which extends a cross member movable in the vertical direction animated by up and down movements. This crosspiece carries a clamp with two jaws opposite a rib provided on the table and a movable scoring knife is disposed between the jaws of this clamp. Means not described successively grip each sheet to be cut and creased and drive means move it along the work table. The precise positioning of the sheet is ensured by staggered, adjustable and eclipsable stops which are carried by a longitudinal shaft connected to the shaft for controlling the vertical movements of the crosspiece.

L'invention a pour but principal d'apporter une simplification considérable à la machine du type décrit dans le brevet cité; cette simplification se traduit par un coût moindre de sa construction et par une plus grande rapidité de réglage pour le changement d'une dimension de caisse à une autre dimension.The main object of the invention is to bring considerable simplification to the machine of the type described in the cited patent; this simplification results in a lower cost of its construction and a greater speed of adjustment for the change from one box dimension to another dimension.

Une machine selon l'invention comprend un magasin à plateau élévateur de feuilles ou de plaques empilées à plat de carton ondulé, la feuille supérieure étant toujours mise à un niveau prédéterminé. Ce magasin est suivi d'un bâti comprenant deux joues espacées parallèles longitudinales qui portent entre elles trois paires de deux arbres parallèles transversaux, tenues espacées dans le sens du déplacement des feuilles. Chaque arbre de chaque paire est pourvu de deux roues d'entraînement espacées en sens transversal et coopérant deux à deux pour entraîner entre elles une feuille en carton. Les roues d'entraînement associées deux à deux définissent un plan de travail situé sensiblement au niveau prédéterminé de la feuille supérieure.A machine according to the invention comprises a magazine with a lifting platform for sheets or plates stacked flat with corrugated cardboard, the upper sheet always being brought to a predetermined level. This store is followed by a frame comprising two spaced longitudinal parallel cheeks which carry between them three pairs of two transverse parallel shafts, held spaced in the direction of movement of the leaves. Each shaft of each pair is provided with two drive wheels spaced transversely and cooperating in pairs to drive between them a cardboard sheet. The drive wheels associated two by two define a work plane located substantially at the predetermined level of the top sheet.

Un cylindre de séparation et d'alimentation est disposé au-dessus des feuilles empilées et il exerce sur la première feuille une pression constante et réglable; sa surface extérieure présente des reliefs. De préférence il est monté sur un arbre transversal porté par un bras en porte à faux articulé sur le bâti par une de ses extrémités et associé à un moyen de soutien. Ce cylindre est entraîné en rotation par l'intermédiaire d'un mécanisme à roue libre.A separating and feeding cylinder is placed above the stacked sheets and exerts on the first sheet a constant and adjustable pressure; its outer surface has reliefs. Preferably it is mounted on a transverse shaft carried by a cantilever arm articulated on the frame by one of its ends and associated with a support means. This cylinder is rotated by a freewheel mechanism.

Sur la première paire d'arbres qui suit le magasin sont montés des galets pour l'exécution des rainages longitudinaux. Entre la première et la deuxième paire d'arbres les joues du bâti supportent des glissières verticales entre lesquelles est montée déplaçable verticalement une traverse pourvue de couteaux transversaux et d'éléments raineurs transversaux réglables en position. Un organe antagoniste s'étend transversalement entre les joues du bâti en dessous du plan de travail, sous la traverse.On the first pair of shafts following the magazine, rollers are mounted for performing the longitudinal grooves. Between the first and the second pair of shafts the cheeks of the frame support vertical slides between which is mounted vertically displaceable a crosspiece provided with transverse knives and transverse grooving elements adjustable in position. An opposing member extends transversely between the cheeks of the frame below the work surface, under the crosspiece.

Tous les arbres transversaux sont pourvus chacun d'un galet denté; un moteur est supporté par le bâti et l'arbre de ce moteur est muni d'une roue dentée. Une même chaîne passe autour de cette roue dentée et de tous les galets. Le moteur comprend un rotor à faible inertie; son fonctionnement est asservi à un circuit électronique comprenant des organes d'affichage de cotes en fonction des caisses à confectionner et des capteurs de présence des feuilles de carton.All the transverse shafts are each provided with a toothed roller; a motor is supported by the frame and the shaft of this motor is provided with a toothed wheel. The same chain goes around this gear wheel and all the rollers. The motor includes a rotor with low inertia; its operation is controlled by an electronic circuit comprising members for displaying dimensions as a function of the boxes to be made and sensors for the presence of the cardboard sheets.

Dans un mode de réalisation de l'invention, entre la deuxième et la troisième paire d'arbres est placé un support horizontal, en dessous du plan de travail, et le bâti présente dans cette zone des moyens de fixation d'une unité d'impression.In one embodiment of the invention, between the second and the third pair of shafts is placed a horizontal support, below the work surface, and the frame has in this area means for fixing a unit of impression.

On donnera maintenant, sans intention limitative, une description d'un exemple de réalisation de l'invention. On se reportera aux dessins annexés dans lesquels :

  • - la figure 1 est une vue en élévation et en coupe par un plan longitudinal d'une machineselon l'invention
  • - la figure 2 est une vue de dessus de la machine de la figure 1 ,
  • - la figure 3 est une vue de détail montrant la traverse de découpage et de rainage et son organe antagoniste ,
  • - la figure 4 est une vue en coupe selon IV-IV de la figure 3.
A description will now be given, without any limiting intention, of an exemplary embodiment of the invention. Reference is made to the appended drawings in which:
  • - Figure 1 is an elevational view in section through a longitudinal plane of a machine according to the invention

  • FIG. 3 is a detail view showing the cutting and creasing cross member and its opposing member,
  • - Figure 4 is a sectional view along IV-IV of Figure 3.

Le mérite de l'invention réside dans la conception générale et dans l'architecture de la machine. Les moyens combinés pour sa réalisation sont connus individuellement. La description qui suit sera donc limitée à la disposition nouvelle des organes et à la description des organes nouveaux quand ceux-ci diffèrent des organes courants. Pour des raisons de clarté du dessin, toutes les pièces ne sont pas représentées sur toutes les figures.The merit of the invention lies in the general design and the architecture of the machine. The combined means for its realization are known individually. The description which follows will therefore be limited to the new arrangement of the organs and to the description of the new organs when these differ from the current organs. For reasons of clarity of the drawing, not all of the parts are shown in all of the figures.

Une machine conforme à l'invention comprend un magasin 1 ayant un plateau élévateur 2 sur lequel sont déposées à plat les feuilles de carton à découper et à rainer. Ce genre de magasin est connu en soi; il a pour rôle d'élever la pile des feuilles de carton à chaque prise de l'une d'elles et de tenir la première feuille à un niveau prédétermine N.A machine according to the invention comprises a magazine 1 having a lifting plate 2 on which are laid flat the cardboard sheets to be cut and creased. This kind of store is known per se; its role is to raise the stack of cardboard sheets each time one of them is taken and to hold the first sheet at a predetermined level N.

Le magasin 1 est suivi d'un bâti général 3 qui comprend deux joues 4A, 4B parallèles, espacées d'une distance légèrement supérieure à celle du magasin 1. Une joue 4A porte par une extrémité un bras oscillant 5 qui s'étend en porte à faux jusqu'à un-niveau supérieur au niveau prédéterminé N et ce bras 5 est pourvu à son extrémité opposée d'un palier 6 à partir duquel un arbre 7 s'étend transversalement au-dessus du plateau 2 et au-dessus des cartons empilés sur ce dernier. Sur cet arbre 7 est calé en rotation un cylindre 8 de séparation et d'alimentation qui présente à sa surface de nombreux reliefs. De préférence, le cylindre 8 est garni d'une couche extérieure en caoutchouc qui montre à sa surface de nombreux têtons distincts les uns des autres. L'arbre 7 est équipé à l'extérieur du palier 6 d'un galet denté 9 sur lequel passe une chaîne 10 dont une extrémité est attachée à une extrémité d'un ressort de rappel 11 et dont l'extrémité opposée est attachée à la tige de piston d'un vérin 12. Le ressort 11 et le vérin 12 sont portés par le bras 5 auquel ils sont fixés. La disposition est telle que toute traction exercée par le vérin 12 sur la chaîne 10 provoque une rotation du cylindre 8 dans le sens indiqué par une flèche F sur la figure 1 qui correspond à la prise de la feuille supérieure de la pile et à son déplacement vers les organes suivants de la machine. L'entraînement en rotation du cylindre 8 à partir du vérin 12 se fait par l'intermédiaire d'un mécanisme à roue libre (non représenté) de sorte que le ressort 11 peut rappeler la tige de piston du vérin 12 à sa position initiale sans agir sur le cylindre 8. En outre, ce dernier peut être mû par la feuille de carton quand celle--ci est tirée par les organes suivants de la machine sans opposer de résistance gênante. Le cylindre 8 est m0 par intermittence par le vérin 12 qui sert de moteur d'alimentation.The magazine 1 is followed by a general frame 3 which comprises two parallel cheeks 4A, 4B, spaced a distance slightly greater than that of the magazine 1. A cheek 4A carries at one end a swinging arm 5 which extends into the door false up to a level higher than the predetermined level N and this arm 5 is provided at its opposite end with a bearing 6 from which a shaft 7 extends transversely above the plate 2 and above the cartons stacked on the latter. On this shaft 7 is fixed in rotation a cylinder 8 of separation and supply which has on its surface many reliefs. Preferably, the cylinder 8 is lined with an outer layer of rubber which shows on its surface many nipples distinct from each other. The shaft 7 is equipped on the outside of the bearing 6 with a toothed roller 9 over which passes a chain 10, one end of which is attached to one end of a return spring 11 and the opposite end of which is attached to the piston rod of a jack 12. The spring 11 and the jack 12 are carried by the arm 5 to which they are fixed. The arrangement is such that any traction exerted by the jack 12 on the chain 10 causes a rotation of the cylinder 8 in the direction indicated by an arrow F in FIG. 1 which corresponds to the grip of the top sheet of the stack and to its movement to the following parts of the machine. The cylinder 8 is driven in rotation from the jack 12 by means of a freewheel mechanism (not shown) so that the spring 11 can return the piston rod of the jack 12 to its initial position without act on the cylinder 8. In addition, the latter can be moved by the sheet of cardboard when the latter is pulled by the following members of the machine without opposing any troublesome resistance. The cylinder 8 is intermittently m0 by the jack 12 which serves as a feed motor.

Le bras 5 est monté en porte à faux; le poids de l'ensemble est reporté par le cylindre 8 sur la première feuille de la pile. Cette force de pression est donc constante. Il peut arriver que, pour certains cartons, cette force soit excessive. Un moyen de soutien est donc associé au bras 5. Ce dernier est monté oscillant autour d'un axe 13 porté par la joue 4A et il est prolongé au-delà de cet axe par une extension 14 qui a un trou 15 de passage d'une tige filetée 16 articulée par une extrémité 16A sur la joue 4A. Un ressort de compression 17 entoure la tige 16 et s'appuie contre l'extension 14. Un écrou 18 se visse sur la tige et permet de régler la compression du ressort 17. Ce dernier agit en sens opposé au poids qui pèse sur la dernière feuille de la pile. On peut régler à une valeur convenable, qui reste constante, la pression du cylindre 8 sur les cartons.The arm 5 is mounted cantilevered; the weight of the assembly is reported by the cylinder 8 on the first sheet of the stack. This pressure force is therefore constant. It may happen that, for certain boxes, this force is excessive. A support means is therefore associated with the arm 5. The latter is mounted oscillating around an axis 13 carried by the cheek 4A and it is extended beyond this axis by an extension 14 which has a hole 15 for passage of a threaded rod 16 articulated by an end 16A on the cheek 4A. A compression spring 17 surrounds the rod 16 and bears against the extension 14. A nut 18 screws onto the rod and makes it possible to adjust the compression of the spring 17. The latter acts in the opposite direction to the weight which weighs on the last stack sheet. The pressure of cylinder 8 on the cartons can be adjusted to a suitable value, which remains constant.

La combinaison du magasin l à plateau élévateur 2 et du cylindre 8 supporté en porte à faux avec un moyen de réglage de la pression exercée sur la pile des cartons est une solution simple et de fonctionnement sûr et précis. L'emploi d'un mécanisme à roue libre avec le cylindre 8 assure une combinaison de fonctionnement avec les organes suivants que l'on décrira maintenant.The combination of the magazine 1 with a lifting platform 2 and the cylinder 8 supported in cantilever with a means of adjusting the pressure exerted on the stack of cartons is a simple solution and of safe and precise operation. The use of a freewheel mechanism with the cylinder 8 ensures a combination of operation with the following members which will now be described.

Entre les joues 4A et 4B du bâti 3 sont montés, en sens transversal parallèle à l'arbre 7 du cylindre 8, trois paires de deux arbres parallèles associés deux à deux. Ces trois paires, respectivement 19, 20, 21, sont espacées dans le sens longitudinal de la machine qui est le sens de déplacement des cartons. Dans chaque paire les deux arbres sont disposés l'un au-dessus de l'autre. L'arbre supérieur (19A, 20A, 21A) et l'arbre inférieur (19B, 20B: 21B) portent chacun deux roues d'entraînement 22, 23, 24. Ces roues sont calées en rotation sur les arbres et sont espacées dans le sens transversal de la machine. Elles ont une surface striée pour assurer l'entraînement de chaque feuille de carton. Chaque arbre supérieur 19A, 29A, 21A est monté mobile en sens vertical dans ses paliers afin que les roues d'entraînement 22, 23, 24 s'accommodent des variations d'épaisseur des cartons.Between the cheeks 4A and 4B of the frame 3 are mounted, in transverse direction parallel to the shaft 7 of the cylinder 8, three pairs of two parallel shafts associated two by two. These three pairs, respectively 19, 20, 21, are spaced in the longitudinal direction of the machine which is the direction of movement of the cartons. In each pair the two trees are arranged one above the other. The upper shaft (19A, 20A, 21A) and the lower shaft (19B, 20B: 21B) each carry two drive wheels 22, 23, 24. These wheels are set in rotation on the shafts and are spaced in the transverse direction of the machine. They have a ridged surface to ensure the drive of each sheet of cardboard. Each upper shaft 19A, 29A, 21A is mounted to move vertically in its bearings so that the drive wheels 22, 23, 24 accommodate variations in the thickness of the cartons.

Les intervalles entre les deux roues 22, 23, 24 de chaque paire définissent un plan de travail horizontal qui est le plan dans lequel les diverses opérations sont exécutées sur les cartons. Ce plan, représenté par un trait mixte et désigné par la référence P sur la figure 1, est situé sensiblement au niveau N mentionné précédemment. Quand la première feuille de la pile des cartons a été séparée des autres et déplacée par le cylindre 8 jusqu'à ce que son bord avant arrive à être saisi par les roues d'entraînement 22, ce sont ces dernières qui assurent le déplacement de cette feuille, grâce à la roue libre du cylindre 8.The intervals between the two wheels 22, 23, 24 of each pair define a horizontal work plane which is the plane in which the various operations are carried out on the cartons. This plane, represented by a dashed line and designated by the reference P in Figure 1, is located substantially at level N mentioned above. When the first sheet of the stack of cartons has been separated from the others and moved by the cylinder 8 until its front edge comes to be gripped by the drive wheels 22, it is the latter which ensure the movement of this sheet, thanks to the free wheel of cylinder 8.

Tous les arbres 19A, 19B, 20A, 20B et 21A, 21B sont également pourvus chacun d'un galet denté 25, 26, 27. Un moteur 28 est supporté entre les joues 4A, 4B par un profilé transversal 29. Sur l'arbre de ce moteur est calée une roue dentée 30. Une même chaîne 31 passe autour de la roue dentée 30 et des pignons dentés 25, 26, 27. Selon l'invention, le moteur 28 est du type à rotor à faible inertie et son fonctionnement est asservi à un circuit électronique qui détermine sa vitesse de rotation et la durée de sa marche en fonction de données qui dépendent des dimensions et du type des cartons et des boites.All the shafts 19A, 19B, 20A, 20B and 21A, 21B are also each provided with a toothed roller 25, 26, 27. A motor 28 is supported between the cheeks 4A, 4B by a transverse profile 29. On the shaft a toothed wheel 30 is propped up with this motor. The same chain 31 passes around the toothed wheel 30 and toothed pinions 25, 26, 27. According to the invention, the motor 28 is of the rotor type with low inertia and its operation is slaved to an electronic circuit which determines its speed of rotation and the duration of its march according to data which depend on the dimensions and the type of cartons and boxes.

Sur les arbres 19A, 19B de la première paire 19 qui suit le cylindre 8 sont montés des galets 32 qui exécutent les rainages longitudinaux sur les feuilles de carton pendant leur déplacement. Ces galets 32 sont aisément réglables en position le long des arbres qui les portent en fonction des boites à confectionner.On the shafts 19A, 19B of the first pair 19 which follows the cylinder 8 are mounted rollers 32 which execute the longitudinal creases on the cardboard sheets during their movement. These rollers 32 are easily adjustable in position along the shafts which carry them according to the boxes to be made.

Sur l'arbre supérieur 20A de la deuxième paire 20 est monté un galet découpeur 33 associé à une contre-lame portée par l'arbre inférieur 20B et à un déflecteur 34. Celui-ci est tenu en place grâce à une plaque transversale 35 qui présente une fente allongée 36. La position de l'ensemble découpeur et du déflecteur 34 est facile à régler selon la largeur finale désirée des feuilles de carton. Ces dernières circulent en étant guidées par la joue 4B contre laquelle frotte un de leurs bords longitudinaux et le galet 33 les découpe à la largeur voulue par rapport à cette joue 4B.On the upper shaft 20A of the second pair 20 is mounted a cutting roller 33 associated with a counter blade carried by the lower shaft 20B and with a deflector 34. This is held in place by virtue of a transverse plate 35 which has an elongated slot 36. The position of the cutter assembly and the deflector 34 is easy to adjust according to the desired final width of the cardboard sheets. The latter circulate while being guided by the cheek 4B against which one of their longitudinal edges rubs and the roller 33 cuts them to the desired width relative to this cheek 4B.

Entre la première paire 19 et la seconde paire 20 des arbres, les joues 4A et 4B supportent des glissières verticales 37 entre lesquelles une traverse 38 est montée déplaçable verticalement, en sens alternés. Les glissières 37 s'élèvent au-dessus du plan P et en dessous de ce dernier se trouve un organe de soutien antagoniste 39 qui soutient la feuille de carton, de façon connue, pour permettre l'exécution correcte des découpes et des rainages transversaux. La traverse 38 comprend des moyens de mise en place et de fixation, avec possibilité de réglage en position, de couteaux 40 et d'éléments raineurs 41. Tout moyen connu peut être utilisé à cette fin. De préférence, les couteaux 40 et. les éléments raineurs 41 ont .un talon 42 qui se loge dans une rainure correspondante 43 ménagée dans la traverse 38 et des plaques de maintien 44 sont appliquées par des vis 45 contre la traverse et contre les couteaux et les éléments raineurs. Les couteaux 40 ont un profil longitudinal en V inversé qui ne crée dans la feuille de carton pendant le découpage aucune force de réaction transversale.Between the first pair 19 and the second pair 20 of the shafts, the cheeks 4A and 4B support vertical slides 37 between which a cross member 38 is mounted movable vertically, in alternating directions. The slides 37 rise above the plane P and below the latter there is an opposing support member 39 which supports the cardboard sheet, in a known manner, to allow the correct execution of the cuts and the transverse grooves. The crosspiece 38 comprises means for positioning and fixing, with the possibility of adjustment in position, knives 40 and creasing elements 41. Any known means can be used for this purpose. Preferably, the knives 40 and. the creasing elements 41 have a heel 42 which is housed in a corresponding groove 43 formed in the cross-member 38 and retaining plates 44 are applied by screws 45 against the cross-member and against the knives and the creasing elements. The knives 40 have an inverted longitudinal V profile which creates no transverse reaction force in the cardboard sheet during cutting.

Un moteur 46 supporté entre les joues 4A et 4B a son arbre 47 réuni par une biellette 48 à un mécanisme 49 à excentration réglable qui est réuni à son tour par une bielle 50 à la traverse 38. Celle-ci exécute donc des mouvements alternés de montée et de descente à une amplitude facilement réglable. Le moteur 46 est également du type à moteur à faible inertie; son fonctionnement est conjugué avec celui du moteur 28.A motor 46 supported between the cheeks 4A and 4B has its shaft 47 joined by a link 48 to a mechanism 49 with adjustable eccentricity which is in turn joined by a link 50 to the crosspiece 38. The latter therefore performs alternating movements of rise and fall at an easily adjustable amplitude. The motor 46 is also of the type with a low inertia motor; its operation is combined with that of the motor 28.

Certaines caisses comportent des pattes d'agrafage prédécoupées. Selon l'invention, entre la première paire 19 et la seconde paire 20 d'arbres, une tige transversale 51 est supportée entre les joues 4A et 4B, avec une liberté d'oscillation. Elle est pourvue à une extrémité d'un bras 52 qui est attelé à la tige de piston d'un vérin 53 qui est articulé à son extrémité opposée sur la joue 4A. Sur la tige 51 sont calées des biellettes 54 qui sont munies à leur extrémité libre d'un galet 55 de découpage des pattes d'agrafage. Les biellettes 54 sont réglables en position le long de la tige 51. Au repos les galets 55 sont espacés vers le haut du plan de travail P. Quand le vérin 53 est mis en service, il provoque la mise en contact des galets 55 avec la feuille de carton. Un organe antagoniste approprié 56, connu en soi, est supporté entre les joues 4A, 4B, en dessous du plan de tra-, vail P.Some boxes have pre-cut stapling tabs. According to the invention, between the first pair 19 and the second pair 20 of shafts, a transverse rod 51 is supported between the cheeks 4A and 4B, with freedom of oscillation. It is provided at one end with an arm 52 which is coupled to the piston rod of a jack 53 which is articulated at its opposite end on the cheek 4A. On the rod 51 are fixed rods 54 which are provided at their free end with a roller 55 for cutting the stapling tabs. The rods 54 are adjustable in position along the rod 51. At rest the rollers 55 are spaced upwards from the work surface P. When the jack 53 is put into service, it brings the rollers 55 into contact with the cardboard sheet. An appropriate antagonist member 56, known per se, is supported between the cheeks 4A, 4B, below the work plane P.

Entre la deuxième paire 20 et la troisième paire 21 d'arbres les joues 4A, 4B s'étendent verticalement au-dessus du plan de travail P et elles sont pourvues d'un moyen de fixation, par exemple une fente allongée '57: dans cette zone, en dessous du plan de travail P entre les joues 4A, 4B est disposé un support horizontal 58. De cette façon, on peut fixer facilement aux joues 4A, 4B, au-dessus du support 58 et du plan de travail P,une unité d'impression (non représentée) capable d'imprimer sur chaque feuille des inscriptions voulues. Cette unité d'impression est commandée pour fonctionner en même temps que la traverse 38.Between the second pair 20 and the third pair 21 of trees cheeks 4A, 4B extend vertically above the work plane P and they are provided with a fastening means, for example an elongated slot "57: in this area, below the work plane P between the cheeks 4A, 4B, is arranged a horizontal support 58. In this way, it is easy to fix to the cheeks 4A, 4B, above the support 58 and the work plane P, a printing unit (not shown) capable of printing the desired inscriptions on each sheet. This printing unit is controlled to operate at the same time as the cross member 38.

La machine de l'invention est réduite aux éléments essentiels qui sont indispensables et dont la position et est facilement réglable. Son fonctionnement approprié au type/ aux dimensions des feuilles ne dépend pas de la mise en place convenable de butées dont le réglage est souvent long et incertain. Au contraire, les déplacements et les arrêts des feuilles sont déterminés par la marche du moteur 28. Il est facile de commander ce dernier, ainsi que le moteur 46 de la traverse 38 et l'unité d'impression, à partir d'un programme qui incorpore les dimensions des feuilles, des échancrures et des rainages à réaliser. Il suffit d'afficher ces dimensions en rapport avec une caisse à confectionner pour que le réglage des avances et des arrêts successifs des feuilles de carton soit effectué. La conception de la machine permet donc un gain de temps appréciable à chaque changement de type de caisse. Seuls quelques capteurs de sécurité, à position fixe, sont nécessaires pour signaler l'absence accidentelle de feuille à certains emplacements de la machine.The machine of the invention is reduced to the essential elements which are essential and whose position and is easily adjustable. Its proper functioning for the type / dimensions of the sheets does not depend on the proper placement of stops, the adjustment of which is often long and uncertain. On the contrary, the movements and stops of the sheets are determined by the running of the motor 28. It is easy to control the latter, as well as the motor 46 of the cross-member 38 and the printing unit, from a program. which incorporates the dimensions of the sheets, notches and creases to be produced. It suffices to display these dimensions in relation to a box to be made for the adjustment of the advances and successive stops of the cardboard sheets to be carried out. The design of the machine therefore saves appreciable time each time the type of box is changed. Only a few fixed position safety sensors are needed to signal the accidental absence of sheets at certain locations on the machine.
