Definitions
- the present invention relates to a separation station poses of a cutting press, including a upper cradle for a separating device and clip bars for transporting the sheets in job.
- the front edges of the respective sheets remain pinched in the clamps of the barbell pliers of the device for transporting leaves and waste of the leaf, after separation of the poses, is driven by the clamp bar to the waste disposal station.
- the sheet is dropped by the bar tongs and received to be stacked on a single storage stack formed between vertical storage stops set in the sheet format to be stacked.
- both modes of operation mentioned above require specific respective bodies and therefore can not be implemented on a station comprising polyvalent organs.
- the device for receiving full leaves requires the presence of a movable organ for the output of the sheets of the clamps and their guidance to inside a storage frame.
- this body mobile must be able to go below the level of the clamp bar and as he has to hold back and push the edges before leaves when opening the tongs of the clamp bar, it must have a comb shape for pass between the clamps and the profile of the bar that holds these tongs.
- This mobile unit for receiving the sheets must therefore be moved relative to the cradle so that actuating means must be provided to move this moving member according to the movement of the cradle upper part of the separation station.
- the object of the present invention is to provide a solution likely to allow, on the same station of a cutting press, to perform as necessary, the separation poses or receipt of the full sheets.
- the subject of the present invention is a station separating the poses of a cutting press according to claim 1.
- the main advantage of this invention is that of make the use of the cutting press more flexible. This solution leads to an economy of investment and leads to an optimal use of the production capacity of the machine.
- FIGS. 1 and 2 represent basically a device for the reception of solid sheets mounted on the separation station cut by the cutting press.
- This device for receiving full sheets has a rectangular frame 1 slidably mounted in a slide 2a of an element of a frame or upper cradle 2 of the separation station, of which only this element is represented in Figure 2.
- the rectangular frame 1 can thus be placed laterally in place or removed from the separation, from the driver's side of the machine according to that we want to collect the cut leaves with the poses cut out linked to each other in order to submit these leaves to one or more operations in another machine, or that one wants to separate the cut poses and the collect as separate piles or packages.
- the frame 1 must be removed and another frame, or the tool "plate” of separation of the poses, must be slipped into the slides 2a of the upper cradle 2.
- This other frame or tool "board” was not shown since it is static and so it's simply moved by the movements vertical upright of the upper cradle 2 ordered by the drive mechanism of the cutting press. This frame of separation of poses is therefore not distinguishable from a traditional setting.
- the frame 1 of the sheet receiving device filled with an ejector member 3 which extends over any the length of the front transverse side of frame 1, relative to in the direction of displacement of the cut sheets 4, transported by the clip bar 23 (FIG. 2) driven by usual way by two chains (not represented) in loops endlessly arranged respectively on both sides of the cutting press to which both ends are attached of the clip bar 23.
- the ejector member 3 is integral with two elements articulation 5a, 5b (FIG. 1) pivotally mounted around a transverse axis 6.
- Each articulation element 5a, 5b comprises a roller 7a, 7b pressed by a tension spring 8a, 8b against a cam 9a, 9b, secured to a pivot shaft 10a, 10b.
- Each cam 9a, 9b has an arm 11a, 11b to which is fixed an end of a return spring 12a, 12b whose other end is attached to a fastening member 13a, 13b, pivotally mounted about the pivot shaft 10a, 10b of the respective cams 9a, 9b.
- Each attachment member 13a, 13b is connected to the shaft 14 of a crank 15 by a connecting arm 16a, 16b, of which one end is articulated to the attachment member 13a, respectively 13b and whose other end is articulated to an axis 17a, 17b separate from the shaft 14 of the crank 15.
- a stop 18a, 18b integral with the cam 9a, respectively 9b extends in the trajectory of the fastening member 13a, 13b.
- a movable stop 19a, 19b eccentric with respect to the shaft 14 extending to the crank 15 is bound by the hinge axis 17a, 17b at each connecting arm 16a, respectively 16b.
- a fixed stop 20a, 20b fixed by spacers 1a, 1b to the frame 1 is disposed in the path of each movable stop 19a, 19b, limiting the displacement of each fastening member 13a, 13b under the effect of pulling the return spring 12a, respectively 12b.
- Each shaft 10a, 10b is still secured to a lever 21a, 21b which ends with a roller intended come into contact with a horizontal bearing surface of bearing 22a, 22b.
- the upper cradle 2 rotates the drive levers 21a, 21b, in the clockwise when the upper cradle 2 goes down and the pull springs 12a, 12b make them rotate in the opposite direction as it rises, the movement of driving levers in the opposite direction resulting from the relaxation return springs 12a, 12b which have been armed during the displacement of the trees 10a, 10b.
- These directions of rotation are those that are observed with reference to FIGS. and 3.
- the cams 9a, 9b are driven in the same direction. Since the radii of the parts of these cams 9a, 9b against which the rollers 7a, respectively 7b press decreases, when have been driven maximum angle of drive levers 21a, 21b, the articulation members 5a, 5b both pivot under the force of the springs of tractions 8a, 8b. Therefore, the ejector member 3 rotates during the descent of the upper cradle 2 to be brought in the position illustrated in phantom in FIG.
- This movement of the ejector member 3 comb-shaped must be accurately synchronized with the movement of right to left ( Figure 2) of the clip bar 23 and with the opening of the tongs 23a.
- This opening is made of the usual way in this type of machine, by a cam 24 ( Figure 2) arranged in the path of the roller lever 23b opening the clamps 23a of the clamp bar 23.
- the teeth of the comb formed by the ejector member 3 pass between the clamps 23a of the clamp bar 23, so that the front edge of sheet 4 is pushed by the ejector member 3 as soon as it is released by the bar of clips 23.
- the clamps 23a of the clip bar must not be open, to allow the clip bar 23 to evacuate the remaining waste after the separation of poses, the cams 24 must be capable of being removed during the transformation of the receiving station.
- the angular displacement of the drive levers 21a, 21b is limited by the horizontal bearing surfaces 22a, 22b, so that if we want to slide the frame 1 of the solid sheet receiving device for remove it from the upper cradle 2 to replace it with the poses separation device (not shown), it is necessary to neutralize the tension springs 12a, 12b which rotate the drive levers 21a, 21b and the cams 9a, 9b secured to the same shaft 10a, respectively 10b and prevent the output of the frame 1 of the receiving device.
- the receiving device 1 of the solid sheets 4 is still provided with a plurality of members 25 to accelerate the descent leaves 4 after opening the clamps 23a.
- These organs are static and spread over the entire surface of the receiving device. They are at a level below that of Box 1, so as to come into contact with the surface of the sheet 4 received, after the opening of the clamps 23a of the clamp bar 23.
- the receiving station still has a device for lifting a portion of the guide-chain 26 on the driver's side of the press cut out, located in front of the opening cam of the clamps 23a of the gripper bar 23.
- This device is represented by Figure 4.
- the guide-chain 26 has a portion mobile hanging from a vertical rod 27 pressed towards its position illustrated in solid lines, by a spring of 28.
- a control crank 29 is attached to a pivot shaft 30 extending in a parallel direction to the direction of displacement of the cut sheets 4, so that the crank moves in a transverse plane.
- Two respective ends of two arms 31 are hinged at a point eccentric to the tree 30.
- the two other respective ends of these two arms are articulated with two other arms 32, of which two other extremities respective ones are articulated on the same elements of supports 33 on which is rotated the shaft 30 of the crank 29.
- Two rollers 34 are rotated on the same axis on which two arms 31, 32 are hinged to each other. Pulling the crank 29 against him, compared to the figure 4, which represents this crank 29 as it stands relative to the driver, the two arms 31, 32 raise the rollers 34 which come at the end of the race lift a scope of the stem 27 (not visible because hidden behind a spacer 33a between the two elements 33), on which presses the compression spring 28.
- This rod 27 is raised in the position shown in phantom on the FIG. 4, so that the opening cam 24 of the clamps 23a of the clamp bar 23 is disengaged.
- This device it is possible to remove storage guides 35 sheets 4 received and stacked, guides on which are fixed the opening cams 24 clamps 23a of the clamp bar 23.

Description
La présente invention se rapporte à une station de séparation des poses d'une presse à découper, comprenant un berceau supérieur pour un dispositif de séparation des poses et des barres de pinces pour le transport des feuilles en travail.The present invention relates to a separation station poses of a cutting press, including a upper cradle for a separating device and clip bars for transporting the sheets in job.
Lors du découpage de feuilles dans une presse à découper, on peut, suivant le genre de travail effectué sur la presse, recueillir les poses séparément sous la forme de piles distinctes ou réceptionner la feuille pleine si celle-ci doit encore passer dans une autre machine pour y subir une autre opération, avant ou après découpage de la feuille et avant la séparation des poses.When cutting leaves in a cutting press, Depending on the kind of work done on the press, collect the poses separately in the form of separate batteries or receive the full sheet if it must still go into another machine to undergo another operation, before or after cutting the sheet and before the separation of the poses.
Dans le premier cas, les bords avants des feuilles respectives restent pincés dans les pinces de la barre de pinces du dispositif de transport des feuilles et le déchet de la feuille, après séparation des poses, est entraíné par la barre de pinces vers le poste d'évacuation des déchets.In the first case, the front edges of the respective sheets remain pinched in the clamps of the barbell pliers of the device for transporting leaves and waste of the leaf, after separation of the poses, is driven by the clamp bar to the waste disposal station.
Dans le second cas, la feuille est lâchée par la barre de pinces et réceptionnée pour être empilée sur une seule pile de stockage formée entre des butées de rangement verticales réglées au format des feuilles à empiler.In the second case, the sheet is dropped by the bar tongs and received to be stacked on a single storage stack formed between vertical storage stops set in the sheet format to be stacked.
Comme on peut le constater, les deux modes opératoires susmentionnés nécessitent des organes respectifs spécifiques et ne peuvent donc pas être mis en oeuvre sur une station comportant des organes polyvalents. De plus, si la séparation des poses ne nécessite qu'un outil statique animé par les déplacements alternatifs du berceau supérieur de la station de séparation des poses, le dispositif de réception de feuilles pleines nécessite la présence d'un organe mobile pour la sortie des feuilles des pinces et leur guidage à l'intérieur d'un cadre de rangement. En effet cet organe mobile doit pouvoir descendre au-dessous du niveau de la barre de pince et comme il doit retenir et pousser les bords avant des feuilles lors de l'ouverture des pinces de la barre de pince, il doit présenter une forme de peigne pour passer entre les pinces et le profil de la barre qui tient ces pinces. Cet organe mobile de réception des feuilles doit donc être déplacé par rapport au berceau en sorte que des moyens d'actionnement doivent être prévus pour déplacer cet organe mobile en fonction du déplacement du berceau supérieur de la station de séparation.As can be seen, both modes of operation mentioned above require specific respective bodies and therefore can not be implemented on a station comprising polyvalent organs. Moreover, if the separation poses only requires a static tool animated by alternative movements of the station's upper cradle separation of the poses, the device for receiving full leaves requires the presence of a movable organ for the output of the sheets of the clamps and their guidance to inside a storage frame. Indeed this body mobile must be able to go below the level of the clamp bar and as he has to hold back and push the edges before leaves when opening the tongs of the clamp bar, it must have a comb shape for pass between the clamps and the profile of the bar that holds these tongs. This mobile unit for receiving the sheets must therefore be moved relative to the cradle so that actuating means must be provided to move this moving member according to the movement of the cradle upper part of the separation station.
Le but de la présente invention est d'apporter une solution susceptible de permettre, sur une même station d'une presse à découper, d'effectuer selon le besoin, la séparation des poses ou la réception des feuilles pleines.The object of the present invention is to provide a solution likely to allow, on the same station of a cutting press, to perform as necessary, the separation poses or receipt of the full sheets.
A cet effet, la présente invention a pour objet une
station de séparation des poses d'une presse à découper
selon la revendication 1.For this purpose, the subject of the present invention is a
station separating the poses of a cutting press
according to
L'avantage principal de cette invention est celui de rendre plus flexible l'utilisation de la presse à découper. Cette solution conduit à une économie d'investissement et conduit à une utilisation optimale de la capacité de production de la machine.The main advantage of this invention is that of make the use of the cutting press more flexible. This solution leads to an economy of investment and leads to an optimal use of the production capacity of the machine.
D'autres particularités et avantages de l'invention
apparaítront à la lecture de la description qui suit et qui
sera faite à l'aide des dessins annexés qui illustrent,
schématiquement et à titre d'exemple, une forme d'exécution
de la station de séparation d'une presse à découper, objet
de la présente invention.
En se référant aux figures 1 et 2, ces figures représentent essentiellement un dispositif pour la réception des feuilles pleines monté sur la station de séparation des poses découpées par la presse à découper.Referring to Figures 1 and 2, these figures represent basically a device for the reception of solid sheets mounted on the separation station cut by the cutting press.
Ce dispositif pour la réception des feuilles pleines
comporte un cadre rectangulaire 1 monté coulissant dans une
coulisse 2a d'un élément d'un châssis ou berceau supérieur 2
de la station de séparation, dont seul cet élément est représenté
sur la figure 2. Le cadre rectangulaire 1 peut
ainsi être mis latéralement en place ou enlevé du poste de
séparation, depuis le côté conducteur de la machine selon
que l'on veut recueillir les feuilles découpées avec les poses
découpées liées les unes aux autres en vue de soumettre
ces feuilles à une ou plusieurs opérations dans une autre
machine, ou que l'on veut séparer les poses découpées et les
recueillir sous forme de piles ou paquets distincts. Dans ce
cas, le cadre 1 doit être retiré et un autre cadre, ou l'outil
"planche" de séparation des poses, doit être glissé dans
les glissières 2a du berceau supérieur 2. Cet autre cadre ou
outil "planche" n'a pas été représenté étant donné qu'il est
statique et qu'il est donc simplement déplacé par les mouvements
verticaux alternatifs du berceau supérieur 2 commandé
par le mécanisme d'entraínement de la presse à découper. Ce
cadre de séparation des poses ne se distingue donc pas d'un
cadre traditionnel.This device for receiving full sheets
has a
Contrairement au cadre du dispositif de séparation des
poses, le cadre 1 du dispositif de réception de feuilles
pleines comporte un organe éjecteur 3 qui s'étend sur toute
la longueur du côté transversal avant du cadre 1, par rapport
au sens de déplacement des feuilles découpées 4, transportées
par la barre de pinces 23 (figure 2) entraínée de
façon habituelle par deux chaínes (non représentées) en boucles
sans fin disposées respectivement des deux côtés de la
presse à découper auxquelles sont fixées les deux extrémités
de la barre de pinces 23.Unlike the framework of the separation
poses, the
L'organe éjecteur 3 est solidaire de deux éléments
d'articulation 5a, 5b (figure 1) montés pivotant autour d'un
axe transversal 6. Chaque élément d'articulation 5a, 5b comporte
un galet 7a, 7b pressé par un ressort de traction 8a,
8b contre une came 9a, 9b, solidaire d'un arbre de pivotement
10a, 10b. Chaque came 9a, 9b présente un bras 11a, 11b
auquel est fixée une extrémité d'un ressort de rappel 12a,
12b dont l'autre extrémité est fixée à un organe d'accrochage
13a, 13b, monté pivotant autour de l'arbre de pivotement
10a, 10b des cames respectives 9a, 9b.The
Chaque organe d'accrochage 13a, 13b est relié à l'arbre
14 d'une manivelle 15 par un bras de liaison 16a, 16b, dont
une extrémité est articulée à l'organe d'accrochage 13a,
respectivement 13b et dont l'autre extrémité est articulée à
un axe 17a, 17b distinct de l'arbre 14 de la manivelle 15.
Une butée 18a, 18b solidaire de la came 9a, respectivement
9b s'étend dans la trajectoire de l'organe d'accrochage 13a,
13b. Une butée mobile 19a, 19b excentrée par rapport à l'arbre
14 se prolongeant jusqu'à la manivelle 15 est lié par
l'axe d'articulation 17a, 17b à chaque bras de liaison 16a,
respectivement 16b. Une butée fixe 20a, 20b fixée par des
entretoises 1a, 1b au cadre 1 est disposée dans la trajectoire
de chaque butée mobile 19a, 19b, limitant le déplacement
de chaque organe d'accrochage 13a, 13b sous l'effet de
la traction du ressort de rappel 12a, respectivement 12b. Each
Chaque arbre 10a, 10b est encore solidaire d'un levier
d'entraínement 21a, 21b qui se termine par un galet destiné
à venir en contact avec une surface d'appui horizontale de
roulement 22a, 22b. En se déplaçant verticalement alternativement
de haut en bas et inversement, le berceau supérieur 2
fait pivoter les levier d'entraínement 21a, 21b, dans le
sens des aiguilles de la montre lorsque le berceau supérieur
2 descend et les ressorts de traction 12a, 12b les font
pivoter en sens inverse lorsqu'il remonte, le mouvement des
leviers d'entraínement en sens inverse résultant de la détente
des ressorts de rappel 12a, 12b qui ont été armés pendant
le déplacement des arbres 10a, 10b. Ces sens de rotation
sont ceux que l'on observe en se référant aux figures 2
et 3.Each
Au cours du déplacement des leviers d'entraínement 21a,
21b dans le sens des aiguilles de la montre, les cames 9a,
9b sont entraínées dans le même sens. Etant donné que les
rayons des parties de ces cames 9a, 9b contre lesquelles les
galets 7a, respectivement 7b appuient diminue, lorsqu'elles
ont été entraínées de l'angle d'entraínement maximum des leviers
d'entraínement 21a, 21b, les organes d'articulation
5a, 5b pivotent tous deux sous la force des ressorts de
tractions 8a, 8b. Par conséquent, l'organe éjecteur 3 tourne
pendant la descente du berceau supérieur 2 pour être amené
dans la position illustrée en traits mixtes par la figure 2.During the movement of the
Ce mouvement de l'organe éjecteur 3 en forme de peigne
doit être synchronisé avec précision avec le déplacement de
droite à gauche (figure 2) de la barre de pinces 23 et avec
l'ouverture des pinces 23a. Cette ouverture est réalisée de
la façon habituelle dans ce type de machine, par une came 24
(figure 2) disposée dans la trajectoire du levier à galet
23b d'ouverture des pinces 23a de la barre de pinces 23.
Ainsi, les dents du peigne que forme l'organe éjecteur 3
passent entre les pinces 23a de la barre de pinces 23, en
sorte que le bord avant de la feuille 4 est poussé par
l'organe éjecteur 3 dès qu'elle est lâchée par la barre de
pinces 23.This movement of the
Etant donné que dans le cas où la station de réception
des feuilles pleines est transformée en station de séparation
des poses, les pinces 23a de la barre de pinces ne doivent
pas être ouvertes, pour permettre à la barre de pinces
23 d'évacuer les déchets restant après la séparation des
poses, les cames 24 doivent pouvoir être enlevées lors de la
transformation du poste de réception.Since in the case where the receiving station
solid sheets are transformed into a separation station
poses, the
Comme on peut le constater notamment sur la figure 2,
le déplacement angulaire des leviers d'entraínement 21a, 21b
est limité par les surfaces d'appui horizontales de roulement
22a, 22b, de sorte que si on veut faire coulisser le
cadre 1 du dispositif de réception de feuilles pleines pour
l'enlever du berceau supérieur 2 pour le remplacer par le
dispositif de séparation des poses (non représenté), il est
nécessaire de neutraliser les ressorts de traction 12a, 12b
qui font tourner les leviers d'entraínement 21a, 21b et les
cames 9a, 9b solidaires du même arbre 10a, respectivement
10b et empêchent la sortie du cadre 1 du dispositif de réception.As can be seen in particular in FIG.
the angular displacement of the drive levers 21a, 21b
is limited by the horizontal bearing
Pour obtenir ce résultat, il suffit de tourner la manivelle
15 solidaire de l'arbre 14 de 180° dans le sens des
aiguilles d'une montre pour la faire passer de la position
des figures 1, 2 à celle illustrée par la figure 3. Dans un
premier temps, il faudra vaincre la force des ressorts de
traction 12a, 12b qui appliquent les butées mobiles 19a, 19b
solidaires des bras de liaison 16a, 16b contre les butées
fixes 20a, 20b. Ce mouvement de la manivelle a pour effet de
faire légèrement tourner les organes d'accrochage 13a, 13b
des ressorts 12a, 12b dans le sens inverse de celui des aiguilles
d'une montre. Une fois la traction du ressort vaincue,
elle agit dans le sens de rotation de la manivelle 15
jusqu'à ce que les organes d'accrochage 13a, 13b rencontrent
les butées 18a, 18b solidaires des cames 9a, 9b et des
leviers d'entraínement 21a, 21b (figure 1) neutralisant la
traction des ressorts 12a, 12b sur la manivelle 15. En terminant
la demi rotation de cette manivelle 15, les leviers
d'entraínement 21a, 21b sont dégagés des surfaces d'appui
horizontales 22a, 22b, comme on peut le constater sur la
figure 3, ce qui permet l'enlèvement du cadre 1 du dispositif
de réception sans interférence des leviers d'entraínement
21a, 21b.To achieve this result, simply turn the
Le dispositif de réception 1 des feuilles pleines 4 est
encore muni d'une pluralité d'organes 25 pour accélérer la
descente des feuilles 4 après l'ouverture des pinces 23a.
Ces organes 25 sont statiques et répartis sur toute la
surface du dispositif de réception. Ils se situent à un
niveau inférieur à celui du cadre 1, de manière à venir en
contact avec la surface de la feuille 4 réceptionnée, après
l'ouverture des pinces 23a de la barre de pinces 23.The
En complément du dispositif de "réception pleine feuille",
la station de réception selon la présente invention
comporte encore un dispositif de soulèvement d'une portion
du guide-chaíne 26 du côté conducteur de la presse à
découper, située devant la came d'ouverture des pinces 23a
de la barre de pinces 23. Ce dispositif est représenté par
la figure 4.In addition to the "full sheet receiving" device,
the receiving station according to the present invention
still has a device for lifting a portion
of the guide-
A cet effet, le guide-chaíne 26 présente une portion
mobile suspendue à une tige verticale 27 pressée vers sa position
basse illustrée en trait plein, par un ressort de
compression 28. Une manivelle de commande 29 est fixée à un
arbre de pivotement 30 s'étendant dans une direction parallèle
à la direction de déplacement des feuilles 4 découpées,
en sorte que la manivelle se déplace dans un plan transversal.For this purpose, the guide-
Deux extrémités respectives de deux bras 31 sont articulées
en un point excentré par rapport à l'arbre 30. Les
deux autres extrémités respectives de ces deux bras sont
articulées à deux autres bras 32, dont deux autres extrémités
respectives sont articulées sur les mêmes éléments de
supports 33 sur lesquels est pivoté l'arbre 30 de la manivelle
29. Deux galets 34 sont pivotés sur le même axe sur
lequel les deux bras 31, 32 sont articulés l'un à l'autre.
En tirant la manivelle 29 contre lui, par rapport à la figure
4, qui représente cette manivelle 29 comme elle se situe
par rapport au conducteur, les deux bras 31, 32 font monter
les galets 34 qui viennent en fin de course soulever une
portée de la tige 27 (non visible parce que cachée derrière
une entretoise 33a entre les deux éléments 33), sur laquelle
appuie le ressort de compression 28. Cette tige 27 est soulevée
dans la position illustrée en traits mixtes sur la
figure 4, en sorte que la came 24 d'ouverture des pinces 23a
de la barre de pinces 23 est dégagée.Two respective ends of two
Grâce à ce dispositif, il est possible d'enlever les
guides de rangement 35 des feuilles 4 réceptionnées et empilées,
guides sur lesquels sont fixées les cames d'ouverture
24 des pinces 23a de la barre de pinces 23. Ce dispositif
n'est cependant pas indispensable, mais il évite le démontage
des cames d'ouverture 24 et permet ainsi un gain de
temps.Thanks to this device, it is possible to remove
