Description

Dispositif de dépilage de plis de courrier par accélération
La présente invention concerne un dispositif de dépilage d'objets plats en particulier de plis de courrier notamment ouverts du type brochures publicitaires ou autres, comportant un chemin d'amenage d'une pile d'objets sur chant en butée contre une rive de taquage, un premier moyen de dépilage disposé devant le premier objet de la pile et constitué d'un organe de translation à une vitesse V1 perpendiculaire à la pile et un moyen de transfert de l'objet dépilé à une vitesse V3.
Unwinding device of mail folds by acceleration
The present invention relates to a device for unstacking flat objects, in particular mailpieces, especially open folds, such as advertising brochures or the like, comprising a feed path of a stack of objects on edge abutting against a jogging edge, first unstacking means arranged in front of the first object of the stack and consisting of a translation member at a speed V1 perpendicular to the stack and means for transferring the object stripped at a speed V3.

De tels dispositifs connus comportent en tant que moyen de dépilage un organe de mise en translation des plis constitué par exemple d'un tambour perforé rotatif dans lequel est créée une dépression et entraînant le premier pli à une vitesse V1. Un organe de transfert est disposé en aval de ce moyen de dépilage, cet organe de transfert étant à une vitesse V3, identique à V1. Un organe destiné à éviter les prises doubles est en général disposé entre ces deux organes, constitué d'un agencement de brosse ou de volet articulé. Such known devices comprise as unstacking means a translational member of the folds consisting for example of a rotary perforated drum in which a depression is created and causing the first fold at a speed V1. A transfer member is disposed downstream of this unstacking means, this transfer member being at a speed V3, identical to V1. An organ designed to avoid double taps is generally disposed between these two members, consisting of a brush arrangement or hinged flap.

De tels dispositifs entraînent une mise en vitesse trop brutale des plis et les organes anti-prises doubles posent des problèmes de fiabilité. Such devices cause a speed too sudden folds and double anti-catch members pose reliability problems.

C'est principalement le cas lorsque les plis traités sont des objets ouverts, du type brochures publicitaires ou autres. Ces brochures peuvent se composer par exemple d'une feuille pliée en plusieurs volets ou de quelques feuilles reliées tel un petit fascicule. Tout dispositif de dépilage classique, basé sur le freinage du pli partant en prise double est alors néfaste et provoque des bourrages ou des déchirements des plis dépilés. This is mainly the case when the treated folds are open objects, such as advertising brochures or others. These brochures can consist for example of a sheet folded in several parts or some sheets connected like a small booklet. Any conventional unstacking device, based on the braking of the fold starting in double grip is then harmful and causes jams or tearing of the folds depilated.

La présente invention résoud ces problèmes en agissant par accélération progressive du pli dépilé afin d'entraîner le glissement du pli partant en prise double et permet un dépilage correct. Il est en particulier parfaitement adapté au dépilage de plis ouverts tels que précédemment décrits, l'objet étant mis en vitesse de façon plus douce. The present invention solves these problems by acting by gradually accelerating the popped fold to cause the sliding of the fold to double engaging and allows proper unstacking. In particular, it is perfectly suitable for unstacking open folds as previously described, the object being speeded up more smoothly.

Pour ce faire, selon l'invention, au moins un second moyen de dépilage est intercalé entre le premier et l'organe de transfert, ce second moyen étant constitué également d'un organe de translation à une vitesse V2 perpendiculaire à la pile et en ce que les vitesses de translation sont différentes et progressives avec Vî < V2 t .... < V3. To do this, according to the invention, at least a second unstacking means is interposed between the first and the transfer member, this second means also consisting of a translation member at a speed V2 perpendicular to the stack and in the translation speeds are different and progressive with V <V2 t .... <V3.

Selon d'autres caractéristiques préférentielles de l'invention - le premier organe de translation est constitué d'une courroie perforée associée à une chambre à dépression permanente disposée derrière cette courroie, - le second organe de translation est constitué d'une courroie perforée associée à une chambre à dépression permanente disposée derrière cette courroie, la trajectoire de translation étant alignée à celle du premier organe de translation, - l'organe de transfert est constitué de deux courroies de convoyage par pincement, la trajectoire de convoyage étant alignée avec les trajectoires de translation des premier et second organes de translation, - les premier et second moyen de dépilage sont disposés de part et d'autre du plan de la rive de taquage, - une chambre à faible dépression permanente est disposée en amont du premier organe de translation. According to other preferred features of the invention - the first translation member consists of a perforated belt associated with a permanent vacuum chamber disposed behind this belt, - the second translation member consists of a perforated belt associated with a permanent vacuum chamber disposed behind this belt, the translation path being aligned with that of the first translation member, - the transfer member consists of two nip conveyor belts, the conveying path being aligned with the trajectories. translation of the first and second translation members, - the first and second unstacking means are disposed on either side of the plane of the jogging edge, - a low permanent vacuum chamber is arranged upstream of the first translation member.

Les fonctions et avantages de ces différentes caractéristiques apparaîtront à la lecture de la description suivante qui ne décrit qu'un mode de réalisation préférée de l'invention à l'aide des dessins. The functions and advantages of these various characteristics will appear on reading the following description which describes only a preferred embodiment of the invention with the help of the drawings.

La figure 1 est une vue de dessus du dispositif de dépilage conforme à l'invention. Figure 1 is a top view of the unstacking device according to the invention.

Les figures 2A et 2B sont des schémas qui permettront de déterminer les conditions de fonctionnement du dispositif selon la longueur des plis traités. Figures 2A and 2B are diagrams that will determine the operating conditions of the device according to the length of the treated folds.

Le dispositif se compose essentiellement - d'un chemin d'amenage sensiblement horizontal d'une pile de plis 1 sur chant en butée contre une rive de taquage 2 sensiblement verticale, - d'un premier organe de translation 3 à une vitesse V1 constitué d'une courroie perforée 6 guidée et actionnée par poulies et associée à une chambre 7 de dépression permanente disposée derrière la courroie 6, sur la trajectoire des plis 1, - d'un second organe de translation 5 à une vitesse V2 également constitué d'une courroie perforée 8 guidée et actionnée par poulies et associée à une chambre 9 de dépression permanente disposée derrière la courroie 8 sur la trajectoire des plis 1, - d'un moyen de transfert 4 à une vitesse V3 constitué de deux courroies 10, 11 guidées et actionnées par poulies et agissant par pincement des plis 1. The device essentially consists of a substantially horizontal feed path of a stack of folds 1 on edge abutting against a substantially vertical jogging edge 2 of a first translation member 3 at a speed V 1 consisting of a perforated belt 6 guided and actuated by pulleys and associated with a permanent vacuum chamber 7 disposed behind the belt 6, on the path of the folds 1, - a second translational member 5 at a speed V2 also consisting of a perforated belt 8 guided and actuated by pulleys and associated with a permanent depression chamber 9 disposed behind the belt 8 on the path of the folds 1, - a transfer means 4 at a speed V3 consisting of two belts 10, 11 guided and driven by pulleys and acting by pinching the folds 1.

Ces trois moyens 3, 4, 5 sont alignés de telle sorte que la trajectoire des plis dépilés soit dans un plan parallèle à celui des plis 1. En amont de celle-ci est disposée une chambre 12 à faible dépression permanente destinée au prépositionnement statique du pli à dépiler. These three means 3, 4, 5 are aligned so that the trajectory of the de-pleated folds is in a plane parallel to that of the folds 1. Upstream thereof is arranged a chamber 12 with a low permanent depression intended for the static prepositioning of the fold to unstack.

Cette chambre 12 ainsi que le premier moyen de translation 3 sont disposés en face de la pile de plis 1 amenée. This chamber 12 and the first translation means 3 are arranged in front of the stack of folds 1 brought.

Le second moyen de translation 5 et le moyen de transfert 4 sont disposés de l'autre côté du plan vertical contenant la rive de taquage 2.  The second translation means 5 and the transfer means 4 are arranged on the other side of the vertical plane containing the jogging edge 2.

Selon une caractéristique essentielle de l'invention, l'on a
V1 < V2 < V3-
A titre d'exemple
V1 = 1 m/s
V2 = 2 m/s
V3 = 3,2 m/s
Les chambres 7, 9 sont à une dépression d'environ 200 mbars et la chambre 12 d'environ 5 à 7 mbars.
According to an essential characteristic of the invention,
V1 <V2 <V3-
For exemple
V1 = 1 m / s
V2 = 2 m / s
V3 = 3.2 m / s
Rooms 7, 9 are at a depression of about 200 mbar and room 12 is about 5 to 7 mbar.

Le fonctionnement du dispositif est le suivant - un pli est poussé contre la chambre 12 et le premier moyen de dépilage 3 ; il est translaté à la vitesse V1, - dès qu'il est avancé, le pli suivant est prépositionné grâce à la chambre 12 à faible dépression, - le pli est accéléré à la vitesse V2 grâce au second moyen de dépilage 5 puis accéléré à la vitesse V3 grâce au moyen de transfert 4. Ces accélérations progressives du pli produisent le glissement du pli suivant partant éventuellement en prise double. The operation of the device is as follows - a fold is pushed against the chamber 12 and the first unstacking means 3; it is translated at the speed V1, - as soon as it is advanced, the next fold is prepositioned thanks to the chamber 12 at low vacuum, - the fold is accelerated to the speed V2 thanks to the second unstacking means 5 and then accelerated to the V3 velocity through the transfer means 4. These progressive acceleration of the fold produce the sliding of the next fold possibly starting in double grip.

Ce fonctionnement suppose que la force de traction du point de pincement l'emporte sur la force de retenue exercée par la chambre 9, cette force étant elle-même supérieure à celle exercée par la chambre 7. This operation assumes that the pulling force of the pinching point outweighs the holding force exerted by the chamber 9, this force being itself greater than that exerted by the chamber 7.

Suivant la longueur L des plis et compte tenu des dimensions a = distance entre la première chambre de dépression 7 et le plan de butée de la rive de taquage 2, b = distance entre la seconde chambre de dépression 9 et le plan de butée de la rive de taquage 2, c = distance entre le pincement du pli par le moyen de transfert 4 et le plan de butée de la rive de taquage 2,
deux cas sont à envisager 1/ le pli n+1 se met en mouvement à la vitesse V1 alors que le pli n est encore à la vitesse V2 (figure 2A), 2/ le pli n+l se met en mouvement à la vitesse V1 alors que le pli n est déjà à la vitesse V3 (figure 2B).
According to the length L of the folds and taking into account the dimensions a = distance between the first vacuum chamber 7 and the stop plane of the jogging edge 2, b = distance between the second vacuum chamber 9 and the stop plane of the jogging edge 2, c = distance between the nip of the fold by the transfer means 4 and the abutment plane of the jogging edge 2,
two cases are to consider 1 / the fold n + 1 starts moving at the speed V1 while the fold n is still at the speed V2 (Figure 2A), 2 / the fold n + 1 starts moving at the speed V1 while the fold n is already at the speed V3 (Figure 2B).

Il peut être calculé les écarts théoriques g entre plis et le débit théorique T. On obtient - dans le cas 1 (figure 2A)
g = (L-a-b) V3 + b V3 - L --L
T = 3600 V3/(L + g) - dans le cas 2 (figure 2B) V3 b (c-b) V3
g = (c-b) V2 + Vî -a-c
T = 3600 V3/(L + g).
It is possible to calculate the theoretical differences between folds and the theoretical flow rate T. We obtain - in case 1 (FIG. 2A)
g = (Lab) V3 + b V3 - L - L
T = 3600 V3 / (L + g) - in case 2 (FIG. 2B) V3 b (cb) V3
g = (cb) V2 + Vl -ac
T = 3600 V3 / (L + g).

Ces équations servent à déterminer les valeurs à donner à a, b, c,
V1, V2, (V3 étant en général fixé) pour avoir l'écart et le débit
3 souhaité.
These equations are used to determine the values to give to a, b, c,
V1, V2, (V3 being generally fixed) to have the gap and the flow
3 desired.

En général l'on cherche à avoir
g t 100 mm
T k 25000 plis/heures.
In general one seeks to have
100 mm
T k 25000 folds / hours.

A titre d'exemples numériques pour a = 0,05 m
b = 0,07 m
c = 0,18 m
V1 = 1 m/s
V2 = 2 m/s
V3= 3,2 m/s l'on obtient le tableau suivant

As numerical examples for a = 0.05 m
b = 0.07 m
c = 0.18 m
V1 = 1 m / s
V2 = 2 m / s
V3 = 3.2 m / s we obtain the following table
