Description

  

   <EMI ID=1.1> 

  
La présente invention est relative à des perfectionnements apportés aux machines coupeuses refouleusen pour produits en bandes ou en feuilles, notamment aux machines de ce "enre utilisées dans l'industrie du carton ondule.

  
Comme on le sait, ces machines servent à couper ou :3 entailler et/ou a refouler le produit en bandes ou en feuilles suivant des lignes parallèles à la direction d'avancement du produit dans la machine.

  
Lorsque les nécessités de la fabrication imposent une modification dans la position de ces lignes, il faut arrêter l'alimentation de la machine en produit pendant un temps appréciable, correspondant au changement des outils. Cette immobilisation ne permet, pas de bénéficier des avantages qui pourraient découler d'une alimentation pratiquement continue et, dans le cas particulier du carton ondule, provoque une surchauffe du produit dans l'installation de séchape précédant la machine avec, pour conséquence, une altération des qualités du carton,

  
La présente invention se propose de remédier à cet état de choses en supprimant l'obligation de cet arrêt dans l'alimentation.

  
L'invention consiste principalement a munir la machine coupeuse refouleusc de deux jeux d'outils

  
 <EMI ID=2.1> 

  
ment, et d'un mécanisme, comprenant au moins un vérin, mettant en position de travail l'un des jeux et en position de repos l'autre jeu, les outils étant mis en

  
 <EMI ID=3.1> 

  
position de travail.

  
L'invention consiste encore en certaines autres dispositions mentionnées ci-après et employées., de préférence, en même temps que la disposition principale ci-des sus énoncée.

  
L'invention vise plus particulièrement certains modes d'application et- de réalisât ion de ces dispositions ; elle vise plus particulièrement

  
 <EMI ID=4.1> 

  
 <EMI ID=5.1> 

  
comprenant ces machines. 

  
A simple titre d'exemnle et pour faciliter la compréhension de l'invention, il est donné ci-après une description de modes particuliers de réalisation

  
 <EMI ID=6.1>

La firure 2, analorue a la figure 1, repré-  sente cette machine au moment du passade en position de travail du deuxième ieu d'outils ;

  
 <EMI ID=7.1>   <EMI ID=8.1> 

  
bande 1 passe dans une cisaille, par exemple entre deux rouleaux coupeurs 2, 3, normalement inactive et dont le rôle cera précise plus loin.

  
La machine comprend des jeux d'outils tour-

Les rouleaux coupeurs 2, 3 redevenant inactifs, le vérin 22 rend horizontal le guide 14. La

  
 <EMI ID=14.1>  en service les outils du support 8 après un réglage éventuel de ces outils.

  
Le cas échéant, certains des guides précités pourront être montés élastiquement ou comprendre des parties élastiques pour permettre un début de déplacement des supports d'outils alors que la bande

  
 <EMI ID=15.1> 

  
par un moteur, le bâti 26 peut être déplacé perpendiculairement à la direction d'avancement de la bande 1 dans la machine.

  
 <EMI ID=16.1> 

  
inférieurs, tels que 31, tournants dans des paliers solidaires de supports mobiles pouvant être élevés ou abaissé, sous l'action d'un ou de plusieurs vérins. Avantageusement, les arbres supérieurs, destinés à recevoir des couteaux, sont, en position de travail,

  
 <EMI ID=17.1> 

  
nière que les couteaux de ces arbres soient pressés contre les couteaux correspondants des arbres inférieurs.

  
 <EMI ID=18.1>  figure 3, le bâti 26 est placé au droit de la bande 1 qui passe entre les outils portés par les arbres

  
30 et 31, ce dernier arbre étant en position haute. Dans cette situation, des tenons 32, 33, respectivement solidaires de la poutre en porte-à-faux 34 et de la base 35 du bâti 26, pénètrent et s'ajustent dans des logements d'une pièce 36. Cette pièce assure ainsi

  
une liaison de l'extrémité libre de la poutre 34

  
avec la base 35 du bâti 26, empêche toute flexion appréciable de cette poutre 34 et maintient, de la sorte, le parallélisme des arbres 30, 31. Un verrou, comprenant un crochet à fourche 37, articulé en 38

  
sur la base 35, et un tenon 39, fixé à la pièce 36, s'oppose à toute séparation de la pièce 36 dû bâti.26.

  
Dans cette position de travail, les arbres

  
30, 31 sont actionnés à partir d'un accouplement coulis-

  
 <EMI ID=19.1> 

  
le bâti 42, fixe par rapport aux rails ?9 ; de plus, les supports mobiles 43 de l'arbre 31 sont en position haute.

  
Afin que les outils puissent suivre les petits déplacements transversaux de la bande 1, la pièce 36

  
 <EMI ID=20.1>  au crochet à fourche 37, la pièce 36 fait rouler,

  
 <EMI ID=21.1> 

  
Pour mettre le dispositif, ci-dessus décrit, à la position de repos des outils, il suffit d'abaisser les supports 43 maintenant les arbres tels que 31. La bande 1 passe alors librement entre les outils. On arrête le mouvement de l'arbre 41 et, en relevant le crochet 37, on désolidarise le bâti

  
 <EMI ID=22.1> 

  
latéralement en le faisant rouler sur les rails 29, l'ouverture 27 et l'accouplement coulissant 40 autorisant ce déplacement.

  
Avant la mise à la position de repos des outils du bâti 26, un autre bâti 45 équipé d'une manière ana-

  
 <EMI ID=23.1>

 <EMI ID=24.1> 

  
de cette bande en mettant en service les outils

  
 <EMI ID=25.1>  

  
Le réglage des outils se fait lorsque les bâtis sont dégagés latéralement de la bande. Bien entendu, la machine peut comprendre plut de deux bâtis de l'espèce.

  
En autre variante, la machine peut avoir deux. jeux d'outils 46, 47 portés par un bâti 48 pouvant

  
 <EMI ID=26.1> 

  
jeux en position de travail et l'autre au repos. Un vérin 50 à double effet provoque le basculement

  
 <EMI ID=27.1> 

  
nécessite une cisaille 51 pour couper une ou plusieurs feuilles dans la bande 1 au moment du basculement du bâti 48, Un volet 52 dirige vers le bas les feuilles

  
 <EMI ID=28.1> 

  
des 53, 54 sont solidaires du bâti 48 ; les guides

  
55 et 56 sont fixes par rapport à ce bâti. Cette variante peut être étendue aux cas où le bâti porte plus de deux jeux d'outils et pivote autour d'un axe pour mettre en position de travail l'un quelconque

  
de ces jeux.

  
La machine coupeuse refouleuse, conforme à l'invention, peut être munie d'un dispositif de programme commandant le passage automatique d'un jeu d'outils à un autre après passade, à l'entrée de la machine, d'une longueur déterminée de bande ou d'un nombre fixe de feuilles. Sans qu'il soit nécessaire de reprendre le détail des opérations, ce dispositif, selon la variante de machine, mettra en rotation les outils réglés, agira sur les vérins 10, 13 ou 50,  actionnera les moteurs des galets 28 des bâtis 26

  
et 45 et les vérins des supports 43. Ces diverses actions, déclenchées automatiquement, peuvent

   <EMI ID = 1.1>

  
The present invention relates to improvements made to upsetting cutting machines for products in strips or in sheets, in particular to machines of this type used in the corrugated cardboard industry.

  
As is known, these machines are used to cut or: 3 notch and / or to push the product into strips or sheets along lines parallel to the direction of advance of the product in the machine.

  
When manufacturing requirements require a modification in the position of these lines, it is necessary to stop the supply of product to the machine for an appreciable time, corresponding to the change of tools. This immobilization does not make it possible to benefit from the advantages which could result from a practically continuous supply and, in the particular case of corrugated cardboard, causes overheating of the product in the drying installation preceding the machine with, for consequence, an alteration. the qualities of the cardboard,

  
The present invention proposes to remedy this state of affairs by eliminating the obligation of this stop in the power supply.

  
The invention consists mainly in providing the upsetting cutting machine with two sets of tools

  
 <EMI ID = 2.1>

  
ment, and a mechanism, comprising at least one jack, placing one of the sets in the working position and the other set in the rest position, the tools being put in

  
 <EMI ID = 3.1>

  
working position.

  
The invention also consists of certain other arrangements mentioned below and used, preferably, at the same time as the main arrangement mentioned above.

  
The invention relates more particularly to certain modes of application and- realization of these arrangements; it aims more particularly

  
 <EMI ID = 4.1>

  
 <EMI ID = 5.1>

  
including these machines.

  
By way of example and to facilitate understanding of the invention, a description of particular embodiments is given below.

  
 <EMI ID = 6.1>

  
longitudinal vertical, a upsetting cutting machine, produced according to the invention, a first set of tools "both in the working position;

  
Firure 2, analogous to FIG. 1, represents this machine at the moment when the second tool passes into the working position;

  
 <EMI ID = 7.1> <EMI ID = 8.1>

  
strip 1 passes through a shear, for example between two cutting rollers 2, 3, normally inactive and the role of which will be specified later.

  
The machine includes lathe tool sets

  
 <EMI ID = 9.1>

  
the direction of travel of the strip 1.

  
The ieu of the support 8. being in the working position

  
 <EMI ID = 10.1>

  
in the.

  
during this phase of operation, the

  
 <EMI ID = 11.1>

  
To pack the work carried out by the tool set ': from the support 8 this one provided for the tools

  
 <EMI ID = 12.1> <EMI ID = 13.1>

  
cut sheet 21 which falls into 24,

  
The cutting rollers 2, 3 becoming inactive again, the jack 22 makes the guide 14 horizontal.

  
 <EMI ID = 14.1> activate the tools of support 8 after any adjustment of these tools.

  
Where appropriate, some of the aforementioned guides may be resiliently mounted or include elastic parts to allow the start of movement of the tool supports while the band

  
 <EMI ID = 15.1>

  
by a motor, the frame 26 can be moved perpendicularly to the direction of advance of the strip 1 in the machine.

  
 <EMI ID = 16.1>

  
lower, such as 31, rotating in bearings integral with movable supports which can be raised or lowered, under the action of one or more jacks. Advantageously, the upper shafts, intended to receive knives, are, in the working position,

  
 <EMI ID = 17.1>

  
nure that the knives of these trees are pressed against the corresponding knives of the lower shafts.

  
 <EMI ID = 18.1> figure 3, the frame 26 is placed to the right of the strip 1 which passes between the tools carried by the shafts

  
30 and 31, the latter shaft being in the high position. In this situation, tenons 32, 33, respectively integral with the cantilever beam 34 and the base 35 of the frame 26, penetrate and fit into one-piece housings 36. This piece thus ensures

  
a connection of the free end of the beam 34

  
with the base 35 of the frame 26, prevents any appreciable bending of this beam 34 and thus maintains the parallelism of the shafts 30, 31. A lock, comprising a fork hook 37, articulated at 38

  
on the base 35, and a tenon 39, fixed to the part 36, opposes any separation of the part 36 from the frame. 26.

  
In this working position, the trees

  
30, 31 are actuated from a sliding coupling

  
 <EMI ID = 19.1>

  
the frame 42, fixed relative to the rails? 9; in addition, the movable supports 43 of the shaft 31 are in the high position.

  
So that the tools can follow the small transverse displacements of the belt 1, part 36

  
 <EMI ID = 20.1> at fork hook 37, part 36 rolls,

  
 <EMI ID = 21.1>

  
To put the device, described above, in the rest position of the tools, it suffices to lower the supports 43 holding the shafts such as 31. The strip 1 then passes freely between the tools. The movement of the shaft 41 is stopped and, by raising the hook 37, the frame is detached

  
 <EMI ID = 22.1>

  
laterally by making it roll on the rails 29, the opening 27 and the sliding coupling 40 allowing this movement.

  
Before putting the tools of the frame 26 in the rest position, another frame 45 equipped in a similar manner.

  
 <EMI ID = 23.1>

  
put in working position when those of the frame
26 move to the rest position so that there is no interruption in production.

  
 <EMI ID = 24.1>

  
of this band by putting the tools into service

  
 <EMI ID = 25.1>

  
The tools are adjusted when the frames are released laterally from the belt. Of course, the machine may include more than two such frames.

  
Alternatively, the machine can have two. sets of tools 46, 47 carried by a frame 48 which can

  
 <EMI ID = 26.1>

  
games in working position and the other at rest. A double-acting cylinder 50 causes the tilting

  
 <EMI ID = 27.1>

  
requires a shear 51 to cut one or more sheets in the strip 1 when tilting the frame 48, A flap 52 directs the sheets down

  
 <EMI ID = 28.1>

  
53, 54 are integral with the frame 48; the guides

  
55 and 56 are fixed relative to this frame. This variant can be extended to cases where the frame carries more than two sets of tools and pivots around an axis to put any one

  
of these games.

  
The upsetting cutting machine, according to the invention, can be provided with a program device controlling the automatic passage from one set of tools to another after passing, at the entrance of the machine, of a determined length. tape or a fixed number of sheets. Without having to go into the details of the operations, this device, depending on the machine variant, will set the adjusted tools in rotation, will act on the jacks 10, 13 or 50, will activate the motors of the rollers 28 of the frames 26

  
and 45 and the support jacks 43. These various actions, triggered automatically, can

8 or 11 does not accomplish too slowly or in an incomplete way.

  
 <EMI ID = 31.1>

  
lowered for their adjustment, this lowering having the effect of engaging the above-mentioned safety device. On the other hand, if the machine is fitted with an input shear, this shear is actuated as long as the tools are not in the pre-position.

  
 <EMI ID = 32.1>

  
as limit switches.

  
Finally, in; the case of maneuvering mechanisms described by two hydraulic cylinders 59, 60 acting simultaneously to move, parallel to itself

  
 <EMI ID = 33.1>

  
hydraulic positive compensation, comprising piston! ', double-acting 64 and 65, respectively secured to the pulls of the pintons 62 and 63. The pistons

  
64, 65 move in the cylinders 66, 67 by delimiting variable volumes 68, 69, 70,: 71, filled with liquid. Pipelines 72 and 73, connecting

  
 <EMI ID = 34.1>

  
69 and 70, ensure the desired equality of movements of the pistons 62, 63. Pressure gauges 74 and 75, connected to. the pipes 72 and? 3, allow the operation of the jacks to be controlled.
