Abstract
Description
La présente invention a pour objet un dispositif de sortie par transfert et soudure différée disposé à la sortie des machines pour la fabrication de sacs en plastique. The present invention relates to an output device by transfer and deferred welding disposed at the outlet of the machines for the manufacture of plastic bags.
On connait des dispositifs de soudure et sortie dont une image est donnée dans la figure 1 et qui fonctionnent sur le principe cidessous décrit. Welding and output devices are known, an image of which is given in FIG. 1 and which operate on the principle below described.
Les rouleaux 1 et 1A sont solidaires et animés d'un mouvement de rotation du type marche-arrêt, la longueur du sac étant obtenue pendant la rotation des dits rouleaux. The rollers 1 and 1A are integral and driven in a rotation movement of the on-off type, the length of the bag being obtained during the rotation of said rollers.
Le mouvement de ces rouleaux est décomposé en trois parties
- Accélération
- Vitesse constante
- Décélération
Les mâchoires 2 et 2A son ouvertes pendant la rotation des rouleaux 1 et 1A et sont en contact entre elles pendant un temps légèrement inférieur au temps d'arrêt des rouleaux.The movement of these rollers is broken down into three parts
- Acceleration
- Constant speed
- Deceleration
The jaws 2 and 2A are open during the rotation of the rollers 1 and 1A and are in contact with each other for a time slightly less than the downtime of the rollers.
Lorsque les mâchoires sont fermées, le sac est en train de se souder. When the jaws are closed, the bag is being welded.
Le couteau 3 coupe la gaine pendant l'arrêt des rouleaux. The knife 3 cuts the sheath while the rollers stop.
Les sacs sont empilés dans un dispositif 4
Le cycle de fabrication du sac peut se décomposer de la façon suivante ( voir figure 2
- TLS - Obtention de la longueur du sac
- TM1 - Temps mort 1
- TSC = Soudure et coupe du sac
- TM2 = Temps mort 2

Le temps mort 1 est nécessaire pour éviter le contact entre les mâchoires avant l'arrêt effectif des rouleaux.The bags are stacked in a device 4
The bag manufacturing cycle can be broken down as follows (see Figure 2
- TLS - Obtaining the length of the bag
- TM1 - Dead time 1
- TSC = Welding and cutting of the bag
- TM2 = Dead time 2
It is the image of the position of the knife
CM is the image of the duration of contact

MF is the image of the duration of the position
closed jaws
R is the image of the movement of the rollers
RA is the image of the duration of the acceleration
rollers
RC is the image of the duration of the speed

RD is the image of the duration of the deceleration
rollers
Dead time 1 is necessary to avoid contact between the jaws before the rollers actually stop.
Le temps mort 2 est nécessaire pour assurer l'ouverture des mâchoires avant le début du défilement de la gaine. Dead time 2 is necessary to ensure the opening of the jaws before the sheath begins to run.
Si la longueur d'un cycle est représentée par 360 degrés, les ordres de grandeur des opération précédentes est le suivant:
Sortie Longueur ( SLC ) = 150 degrés
Temps mort 1 ( TM1 ) = 30 degrés
Soudure et coupe ( TSC ) = 150 degrés
Temps mort 2 ( TM2 ) = 30 degrés
Total = 360 degrés
Le début de la coupe (3) coincide avec le début du contact des mâchoires (2 et 2A); la durée de ce contact est de l'ordre de 50 degrés.If the length of a cycle is represented by 360 degrees, the orders of magnitude of the previous operations are as follows:
Exit Length (SLC) = 150 degrees
Dead time 1 (TM1) = 30 degrees
Welding and cutting (TSC) = 150 degrees
Dead time 2 (TM2) = 30 degrees
Total = 360 degrees
The start of the cut (3) coincides with the start of the contact of the jaws (2 and 2A); the duration of this contact is of the order of 50 degrees.
La durée du cycle étant le temps écoulé entre deux débuts de mouvement des rouleaux, la caractéristique de celui ci-dessus décrit est que le sac banal N est entièrement fabriqué dans le cycle N, c'està-dire le premier sac est entièrement fabriqué dans le premier cycle et le cent-vingt-huitième est entièrement fabriqué dans le cycle numéro cent-vingt-huit. The duration of the cycle being the time elapsed between two beginnings of movement of the rollers, the characteristic of the above described is that the standard bag N is entirely manufactured in the cycle N, i.e. the first bag is entirely manufactured in the first cycle and the one hundred and twenty-eighth is entirely made in cycle number one hundred and twenty-eight.
Les systèmes du type que nous venons de décrire présentent l'inconvénient de ne pas pouvoir augmenter la partie du cycle d'obtention de la longueur (TLS) sans diminuer la partie ccrrespondante à la soudure et coupe (TSC), et inverseinent de ne pas pouvoir augmenter la partie consacrée à la soudure fisc) sans diminuer celle pendant laquelle on obtient la longueur du sac ITLS). The systems of the type that we have just described have the disadvantage of not being able to increase the part of the cycle of obtaining the length (TLS) without decreasing the part corresponding to the welding and cutting (TSC), and inversely not to be able to increase the part devoted to tax welding) without decreasing that during which the length of the ITLS bag is obtained).
L'objet de la présente invention est d'augmenter simultanément et de façon très sensible et les deux parties du cycle pour obtenir (dans les mêmes caractéristiques de vitesse des rouleaux et température des mâchoires une augmentation ircrtant= de la production des machines (mesurée en mètres/minute) et de l'épaisseur de la gaine (mesuré en microns) et dont le principe consiste à terminer la fabrication du sac dans un cycle diffèrent de celui dans Icquel on a obtenu sa longueur. The object of the present invention is to simultaneously and very significantly increase both parts of the cycle to obtain (in the same characteristics of the speed of the rollers and temperature of the jaws a significant increase = in the production of the machines (measured in meters / minute) and the thickness of the sheath (measured in microns) and the principle of which consists in finishing the manufacture of the bag in a cycle different from that in which the length was obtained.
Un dispositif permettant la réalisation de ce principe est représenté dans la figure 3 . II n'est pas limitatif. A device allowing the realization of this principle is represented in FIG. 3. It is not limiting.
Dans cette figure les rouleaux (5 et 5A) sont animés d'un mouvement de rotation du type marche-arrêt: la longueur du sac est obtenue pendant le mouvement des dits rouleaux. In this figure the rollers (5 and 5A) are driven in a rotation movement of the on-off type: the length of the bag is obtained during the movement of said rollers.
A l'arrêt des rouleaux. le bras preneur (ü) qui est composé de deux supports latéraux pivotants (16) . d'une barre transversale (17) et d'un système de préhension (7). met le dispositif de préhension (7) au contact de la gaine. et rendent celle-ci solidaire du dit bras preneur (6). When the rollers stop. the gripper arm (ü) which is composed of two pivoting lateral supports (16). a crossbar (17) and a gripping system (7). puts the gripping device (7) in contact with the sheath. and make it integral with said taker arm (6).
Dans le cas présent ie dispositif de préhension est constitué par un système de ventouses; il n'est pas limitatif. In the present case, the gripping device is constituted by a system of suction cups; it is not limiting.
A ce moment la lame de coupe ( 8 ) coupe la gaine et nous obtenons alors un tube non soudé qui deviendra le sac si. At this moment the cutting blade (8) cuts the sheath and we then obtain an unwelded tube which will become the bag if.
Des la fin de la coupe. le bras preneur ( 6 ) descend et les rouleaux (5 et SA) recommencent leur mouvement pour donner une nouvelle longueur de gaine qui deviendra le sac s2. Le premier cycle est terminé et le cycle numéro deux commence. From the end of the cut. the gripper arm (6) goes down and the rollers (5 and SA) start again their movement to give a new length of sheath which will become the bag s2. The first cycle is complete and cycle number two begins.
Une chaine de transfert (9) prend en charge le sac sl par l'intermédiaire d'un autre système de préhension (1 0). lequel système est dans le cas présent constitué par des ventouses. et n'est pas limitatif. A transfer chain (9) takes care of the sl bag via another gripping system (1 0). which system is in the present case constituted by suction cups. and is not limiting.
Le sac sl se trouve alors dans la position sv l'aspiration des ventouses (7) est coupée et le bras preneur (6) remonte à sa position d'attente. The sl bag is then in the sv position the suction of the suction cups (7) is cut and the gripper arm (6) goes back to its standby position.
La chaîne de transfert exécute alors un mouvement ramenant l'extrémité du sac à souder de la position s11 à la position s 12. The transfer chain then performs a movement bringing the end of the welding bag from position s11 to position s 12.
Un jeu de mâchoires (11 et 11A) se fervent alors pour réaliser la soudure du sac et ne s'ouvriront que juste avant l'exécution d'un nouveau pas de la chaîne de transfert qui aura lieu au cycle numéro trois. A set of jaws (11 and 11A) are then used to weld the bag and will not open until just before the execution of a new step of the transfer chain which will take place in cycle number three.
Le pas suivant (position du sac s13) est utilisé pour laisser à la soudure le temps de refroidir avant de déposer l'extrémité du sac sur la pile de saoe en attente d'evacuation. The next step (bag position s13) is used to allow the weld to cool down before depositing the end of the bag on the pile of saoe awaiting evacuation.
Le sac est désolidarisé de la chaine de transfert par suppression de l'aspiration sur les ventouses (10) lorsque celles-ci se trouvent dans la position de dépose représenté par la position S14 du sac (Voir figure 4). The bag is detached from the transfer chain by removing the suction on the suction cups (10) when these are in the removal position represented by the position S14 of the bag (See Figure 4).
Les ventouses (10) sont fixées sur une barre (12) laquelle comporte un lisseur (15) constitué d'une une brosse rectiligne à poils souples et anti-statiques dont le rdle est de lisser le fond su sac supérieur de la pile avant la dépose du sac qui vient d'être terminé (figure 4).Ce systeme de lissage n'est pas limitatif. The suction cups (10) are fixed on a bar (12) which comprises a straightener (15) consisting of a rectilinear brush with flexible and anti-static bristles whose rdle is to smooth the bottom of the upper bag of the stack before the removal of the bag which has just been completed (figure 4). This smoothing system is not limiting.
Le dispositif comporte aussi une mâchoire de façonnage (18) équipée de poinçons (19) permettant la perforation de trous sur la totalité de la pile ou sac à sac et une lame (13) pouvant effectuer des coupes ou prédécoupes et qui est solidaire de la mâchoire (18), l'ensemble étant commandé par un jeu de vérins synchronisés avec l'arrêt de la chaîne de transfert (systeme de commande non limitatif)
Les poinçons (19) sont interchangeables en fonction de la forme et les dimensions souhaités.The device also comprises a shaping jaw (18) equipped with punches (19) allowing the perforation of holes on the whole of the stack or sack bag and a blade (13) capable of making cuts or precuts and which is integral with the jaw (18), the assembly being controlled by a set of jacks synchronized with the stopping of the transfer chain (non-limiting control system)
The punches (19) are interchangeable depending on the desired shape and dimensions.
La lame de découpe (13) peut être rendue inopérante par rapport à la mâchoire (18). The cutting blade (13) can be made inoperative relative to the jaw (18).
Une bande transporteuse (14) extrait la pile lorsque le nombre de sacs empilés égale le nombre de sacs présélectionné. A conveyor belt (14) extracts the stack when the number of bags stacked equals the preselected number of bags.
