Abstract

The apparatus permits the forwarding of the product units by means of a pair of conveyor belts (1 and 2) which bring the said units onto a pair of take-off discs (5). The product units arrive in the pairs of lines of thin strips (6) and are retained in their slots (7) which permit their uniformly distributed and partially superposed arrangement. Used in this manner, the product units arrive, moving forward towards the expulsion bars (8) which enable them to be expelled from the retaining slots (7) and for them to be stored on a stationary reception and discharge plane (9) vertically in line with the take-off discs (5). Provided at the centre is a separating wheel (10) with separating blades (11) defining successive identical spaces for housing the formed packets (12) for inserting into the packing machine. When the prearranged number of product units for each packet is reached, the separating wheel (10) suddenly accelerates and brings its small blade (11), from the position of alignment with the pair of blades (6), so as to be inserted between the final unit provided for the packet and the following unit in storage phase. In this manner, the packets (12) will be separated by releasing the packet at the packet reception point. <IMAGE>

Description

La presente invention concerne un dispositif d'accumulation et de comptage d'objets en papier, tels que des mouchoirs en cellulose ou autre, qui est relié aux machines automatiques empaqueteuses.The present invention relates to a device for accumulating and counting paper objects, such as cellulose handkerchiefs or the like, which is connected to automatic packaging machines.

De manière principale, on effectue en continu le comptage et l'accumulation au point de déchargement des unités de produit qui avancent sur une paire de disques munis de fentes de retenue qui coopèrent avec des palettes de séparation positionnées à l'intérieur des deux disques de prélèvement, pour permettre d'envoyer facilement vers la phase de conditionnement des paquets comptés suivant les valeurs prédéterminées.Mainly, the counting and the accumulation at the unloading point are carried out continuously of the units of product which advance on a pair of discs provided with retaining slots which cooperate with separating pallets positioned inside the two discs of sampling, to allow easy sending to the packaging phase of the packages counted according to the predetermined values.

Actuellement, pour prélever les unités de produit des disques de prélèvement et réaliser leur dispositions en paquets, suivant des valeurs programmables, on utilise en général des plans de réception et d'évacuation horizontaux coopérant de diverse manière avec des barres d'extraction mobiles. Il s'agit de systèmes de coût élevé qui ne permettent pas une variabilité rapide dans les programmes de production du fait que, pour prédisposer une diversification de fonctionnement, il faut procéder au remplacement de leurs pièces.At present, in order to take the units of product from the picking discs and to carry out their arrangement in packages, according to programmable values, horizontal reception and evacuation planes are generally used which cooperate in various ways with mobile extraction bars. These are high cost systems which do not allow rapid variability in the production programs since, to predispose a diversification of operation, it is necessary to replace their parts.

On connaît d'après le brevet DE-B-1079078, un dispositif pour l'entraînement de paquets de papier dans une machine pour le conditionnement de feuilles de papier en paquets, lequel comprend un bras tournant autour d'un axe horizontal et muni d'une pluralité de palettes de réception des feuilles, lesquels sont alimentées par un transporteur à bande de manière à permettre le dépôt de celles-ci, en nombre prédéterminé, sur des plaques de support profilées correspondantes. Chacune de ces plaques est supportée et entraînée en mouvement par un bras correspondant, lequel, à l'extrémité opposée à celle de support de la plaque, est relié à un levier équipé d'un rouleau coulissant sur la piste d'une première et d'une deuxième came sous la commande d'un arbre moteur correspondant.DE-B-1079078 discloses a device for driving packets of paper in a machine for packaging sheets of paper in bundles, which comprises an arm rotating about a horizontal axis and provided with a plurality of pallets for receiving the sheets, which are fed by a conveyor belt so as to allow them to be deposited, in predetermined number, on corresponding profiled support plates. Each of these plates is supported and driven in movement by a corresponding arm, which, at the opposite end to that of support of the plate, is connected to a lever equipped with a roller sliding on the track of a first and d 'a second cam under the control of a corresponding motor shaft.

Mais avec ledit dispositif connu, en raison du positionnement de chaque plaque en correspondance du compartiment de réception du paquet de feuilles correspondantes, il peut se produire la sortie de la dernière feuille recueillie avant que celle-ci ne soit arrivée en correspondance du point de butée finale respectif, en raison d'une augmentation de volume due aux plis qui se forment et en raison de la vitesse de fonctionnement relativement élevée qui entraîne une déformation substantielle du produit. De ce fait, il n'est pas possible d'obtenir des productions au-delà d'une valeur prédéterminée. Par ailleurs, les différents paquets ne sont pas maintenus dans la position correcte de chaque côté, mais seulement en correspondance d'un côté.But with said known device, due to the positioning of each plate in correspondence of the receiving compartment of the packet of corresponding sheets, it can occur the exit of the last sheet collected before it has arrived in correspondence of the stop point respective final, due to an increase in volume due to the folds which form and due to the relatively high operating speed which causes substantial deformation of the product. As a result, it is not possible to obtain productions beyond a predetermined value. Furthermore, the different packages are not kept in the correct position on each side, but only in correspondence on one side.

On connaît également d'après le brevet DE-B-2461002, un dispositif pour la réception de produits en cellulose en paquets, prélevés au moyen d'une roue munie de plusieurs poches radiales pour recevoir les produits alimentés par un transporteur à bande, dans lequel, sur les deux côtés de la roue, sont montés plusieurs bras avec une plaque profilées de réception des feuilles, agissant en direction radiale par rapport à la roue et commandés par des moyens à came correspondants, de manière à permettre le regroupement d'un nombre prédéterminé et le transfert successif à une roue munie de plusieurs compartiments pour la réception des paquets ainsi formés. Lesdits moyens à coulissement radial sont montés sur le même arbre que la première roue, mais de manière que la vitesse angulaire respective soit inférieure. Mais dans ce cas également, la production est faible, du fait qu'il n'est pas possible d'augmenter excessivement la vitesse de fonctionnement desdits bras de par la présence des cames de commande respectives.Also known from patent DE-B-2461002, a device for receiving cellulose products in packages, taken by means of a wheel provided with several radial pockets to receive the products fed by a belt conveyor, in which, on the two sides of the wheel, are mounted several arms with a profiled receiving plate sheets, acting in a radial direction relative to the wheel and controlled by corresponding cam means, so as to allow the grouping of a predetermined number and the successive transfer to a wheel provided with several compartments for the reception of the packages thus formed . Said radial sliding means are mounted on the same shaft as the first wheel, but so that the respective angular speed is lower. But in this case also, the production is low, because it is not possible to excessively increase the operating speed of said arms due to the presence of the respective control cams.

Lesdits inconvénients tecniques sont résolus, conformément à la presente invention, en adoptant l'idée de réaliser un dispositif ayant les caractéristiques décrites dans la revendication 1. D'autres caractéristiques de l'invention sont objet des revendications 2 à 8.Said technical drawbacks are resolved, in accordance with the present invention, by adopting the idea of producing a device having the characteristics described in claim 1. Other characteristics of the invention are the subject of claims 2 to 8.

Conformément à l'invention, il est possible réaliser au moyen de palettes de séparation l'intervention de séparation sur les unités de produit en accumulation provenant de la paire de disques de prélèvement. Ces palettes de séparation, montées de manière équidistante sur une roue, tournent à un apte choisie vitesse angulaire de telle façon que chaque palette soit positionable entre la dernière unité d'un paquet d'unités de produit terminé et l'unité de produit suivante. Avantageusement lesdites palettes sont tournent à vitesse constante jusqu'à la dernière unité de produit d'un paquet déterminé; et dans cette position, elles sont avantageusement soumises à une choisie augmentation de vitesse. La palette de séparation est introduite entre la dernière unité prévue pour le paquet formé et la première unité du paquet en formation, en déterminant ainsi successivement la séparation du paquet ainsi formé qui, au moyen de chaînes de transport, est expulsé du point de comptage. De cette manière, en prédisposant les réglages angulaires et les paramètres des moyens qui déterminent les fentes de retenue sur les disques de prélèvement et des palettes de séparation, il est possible de parvenir techniquement au dispositif. Dans ledit dispositif, en modifiant de manière appropriée le rapport de rotation entre les disques de prélèvement et la roue de support des palettes de séparation, il est possible de former des paquets de différents nombres d'unités afin d'adapter le dispositif aux besoins spécifiques d'utilisation.According to the invention, it is possible to carry out by means of separation pallets the intervention of separation on the units of product in accumulation coming from the pair of sampling discs. These separation pallets, mounted equidistantly on a wheel, rotate at a suitable angle speed so that each pallet can be positioned between the last unit of a packet of finished product units and the next product unit. Advantageously, said pallets are rotated at constant speed until the last unit of product in a given package; and in this position, they are advantageously subjected to a chosen speed increase. The separation palette is introduced between the last unit provided for the packet formed and the first unit of the packet being formed, thereby successively determining the separation of the packet thus formed which, by means of transport chains, is expelled from the counting point. In this way, by predisposing the angular adjustments and the parameters of the means which determine the retaining slots on the sampling discs and separation pallets, it is possible to reach the device technically. In said device, by appropriately modifying the rotation ratio between the picking discs and the support wheel of the separation pallets, it is possible to form bundles of different numbers of units in order to adapt the device to specific needs of use.

Le dispositif peut prévoir l'acheminement des unités de produit au moyen d'une paire concomitante de bandes de transport 1 et 2 sur des rouleaux 3 et 4 qui alimentent lesdites unités sur une paire de disques de prélèvement 5 (comme représenté sur la fig. 1).The device can provide for the conveyance of the product units by means of a concomitant pair of conveyor belts 1 and 2 on rollers 3 and 4 which feed the said units on a pair of sampling discs 5 (as shown in FIG. 1).

Dans des types particuliers de machines plieuses, il n'est pas possible d'appliquer des bandes de transport des unités en progression, dans ce cas il est prévu le positionnement de la paire de disques de prélèvement 5 directement adjacent au cylindre de pliage 14 (comme représenté sur la fig. 4) qui maintient adhérentes les unités de produit déjà formées jusqu'au point de tangence des disques de prélèvement. Après la phase de libération, les segments en progression arriveront directement dans les fentes de retenue des disques de prélèvement. Le dispositif prévoit l'acheminement des unités de produit sur une paire de disques de prélèvement 5. Successivement, les unités de produit arrivent dans les paires de lignes de lamelles 6 et sont retenues dans leurs fentes 7 qui permettent leur disposition uniformément répartie et en superposition partielle, condition qui permet de réduire la vitesse de progression. Ainsi utilisées, les unités de produits arrivent en avançant aux barres d'expulsion 8 qui permettent leur expulsion hors des fentes de retenue 7 et leur accumulation sur un plan de réception et d'évacuation 9 fixe, disposé à la verticale des disques de prélèvement. Au centre, entre la paire de disques de prélèvement 5, il est prévu une roue de séparation 10 comportant sur sa circonférence un ensemble de palettes de séparation saillantes 11 uniformément réparties, disposées radialement, délimitant des espaces identiques en succession de logement des paquets formés à introduire dans la machine à empaqueter. Lorsque le nombre d'unités de produit prédisposé pour un paquet est atteint, on effectue une brusque accélération de la roue de séparation 10 qui amène sa palette 11 d'interférence (qui effectue la séparation) de la position d'alignement avec la paire de lignes de lamelle 6 sur les disques de prélèvement 5 à s'introduire entre la dernière unité prévue pour le paquet et l'unité suivante en phase d'accumulation. De cette manière, on obtiendra la séparation des paquets avec le relâchement successif du paquet formé sur le plain 9 de réception des paquets 12 et le maintien en suspension du paquet en formation sur la palette 11 jusqu'à ce la chaîne de transport 13 libère de manière séquentielle le plain de réception des paquets.
Les paquets ainsi formés sont poussés par des chaînes de transport 13 munies d'éléments 17 saillants du plan lui-même qui, en agissant de manière séquentielle, libèrent le plain de réception 9 des paquets formés 12 et transportent le produit jusqu'à la machine à empaqueter.In particular types of folding machines, it is not possible to apply conveyor belts for advancing units, in this case provision is made for positioning the pair of sampling discs 5 directly adjacent to the folding cylinder 14 ( as shown in Fig. 4) which keeps the product units already adherent formed up to the point of tangency of the sampling discs. After the release phase, the advancing segments will arrive directly in the retaining slots of the sampling discs. The device provides for the routing of the product units on a pair of sampling discs 5. Successively, the product units arrive in the pairs of strip lines 6 and are retained in their slots 7 which allow them to be arranged uniformly distributed and superimposed partial, a condition which makes it possible to reduce the speed of progression. Thus used, the product units arrive by advancing to the expulsion bars 8 which allow their expulsion out of the retaining slots 7 and their accumulation on a fixed receiving and evacuation plane 9, arranged vertically from the sampling discs. In the center, between the pair of picking discs 5, there is provided a separation wheel 10 comprising on its circumference a set of projecting separation pallets 11 uniformly distributed, arranged radially, delimiting identical spaces in succession for housing the packages formed at introduce into the packaging machine. When the number of units of product predisposed for a package is reached, there is a sudden acceleration of the separation wheel 10 which brings its interference pallet 11 (which performs the separation) from the alignment position with the pair of coverslip lines 6 on the sampling discs 5 to be introduced between the last unit provided for the package and the next unit in accumulation phase. In this way, the separation of the packages will be obtained with the successive release of the package formed on the plain 9 for receiving the packages 12 and the suspension of the package being formed on the pallet 11 until the transport chain 13 releases from sequentially the plain reception of packets.
The packages thus formed are pushed by transport chains 13 provided with elements 17 projecting from the plane itself which, by acting in a sequential manner, release the receiving plane 9 from the formed packages 12 and transport the product to the machine. to package.

Pour alimenter des machines empaqueteuses à entrée inclinée de 45° ou moins, on prédisposera le paquet de produit de manière verticale sur les guides d'extraction 15 (comme représenté sur la fig. 5) et, avec une rotation appropriée de la roue de séparation 10, on aura le maintien en position verticale du paquet en formation. A l'arrivée de la dernière unité sur le paquet en formation, on aura l'alignement de la palette de séparation 11 avec les lamelles 6 des disques de prélèvement 5, suivra ensuite une brusque accélération de la roue de séparation 10 en réalisant ainsi la séparation des paquets en formation (comme représenté sur la fig. 6). On obtiendra ainsi une alimentation en continu des paquets de produit qui, en appui sur les guides 15 et maintenus séparés par les palettes 11 placées sur la roue de séparation 10, atteindront en avançant le plan de réception 16 où les éléments 17 saillants du plan 16 de réception et poussés par des chaînes de transport permettront de manière séquentielle de libérer le plan de réception et d'évacuation 16 et de transférer le produit jusqu'à la machine à empaqueter. En particulier, avec le système selon l'invention, il est possible de positionner le plan 16 avec la chaîne 13 de transport avec différentes inclinaisons sans compromettre le fonctionnement correct du dispositif.To feed packaging machines with inclined entry of 45 ° or less, the product pack will be predisposed vertically on the extraction guides 15 (as shown in fig. 5) and, with an appropriate rotation of the separation wheel 10, we will maintain the vertical position of the package being formed. When the last unit arrives on the formation packet, the separation pallet 11 will be aligned with the lamellas 6 of the sampling discs 5, then a sudden acceleration of the separation wheel 10 will follow, thus achieving the separation of the packets in formation (as shown in fig. 6). There will thus be a continuous supply of product packages which, bearing on the guides 15 and kept separated by the pallets 11 placed on the separation wheel 10, will reach advancing the reception plane 16 where the projecting elements 17 of the reception plane 16 and pushed by transport chains will allow sequentially to release the reception and evacuation plan 16 and to transfer the product to the packaging machine . In particular, with the system according to the invention, it is possible to position the plane 16 with the transport chain 13 with different inclinations without compromising the correct functioning of the device.

Fig. 2 is a detailed view of the device of FIG. 1 to highlight the condition of alignment of the pallet 11 of the wheel 10 with the lamella 6 of the sampling disc 5 to allow, during the successive acceleration phase, the introduction of said pallet 11 between the last product unit of the package formed and the new package being formed. Fig. 3 is a top view of the device according to the invention in which a product unit 18 can be seen before arriving at the pair of sampling discs 5. In Table 2, FIG. 4 is a view of another system for transporting the product to the sampling discs 5 produced by means of a folding cylinder 14. FIG. 5 is a view in longitudinal section of the device intended for feeding packaging machines which use an inclined input chain. Fig. 6 is a detailed view of the device of FIG. 5 in the phase preceding the extraction of the product unit from the retaining slot 7 of a strip 6. We can see in this figure the condition of alignment of the separation pallet 11 with the strip 6. The device can be variously made and adapted in its diagram and its components to specific needs of use. In table 3 fig. 7 is a variant of the device of FIG. 5 and FIG. 8 is the view of the device of FIG. 7.

En particulier il est prévu, conformément à l'invention, de dimensionner le diamètre de la roue (10) de manière que, asservie à un mouvement de rotation constant, sa vitesse périphérique est telle qu'elle permet la dépassement d'une lamelle (6) des disques (5) de la part de la palette (11) de la roue (10) qui se trouve à chaque fois, dans le sens du mouvement, par derrière, c'est-à-dire après la dernière unité de produit qui compose le paquet (12). D'autre part, ceci entraîne l'augmentation du rayon de la roue (10) par rapport à celle de Fig. 5, ce qui entraîne, pour un même nombre de palettes (11) et des unités qui composent le paquet (12), la distance angulaire entre deux palette consécutives est supérieure à celle de la roue de la Fig.5, de sorte que les unités de produit ne sont plus maintenues serrées les unes avec les autres ni toutes disposées exactement perpendiculaires aux guides (15), mais diversement inclinées vers la droite; si les unités de produit étaient ainsi abandonnées, elles seraient ensuite transportées jusqu'à la machine de conditionnement de manière irrégulière et de plus des imperfections se produiraient dans le paquet emballé.In particular, provision is made, in accordance with the invention, to size the diameter of the wheel (10) so that, subject to a constant rotational movement, its peripheral speed is such that it allows a blade to be passed ( 6) discs (5) on the part of the pallet (11) of the wheel (10) which is each time, in the direction of movement, from behind, that is to say after the last unit of product that makes up the package (12). On the other hand, this results in an increase in the radius of the wheel (10) compared to that of FIG. 5, which results, for the same number of pallets (11) and of the units that make up the package (12), the angular distance between two consecutive pallet is greater than that of the wheel of Fig.5, so that the product units are no longer held tight with each other or all arranged exactly perpendicular to the guides (15), but variously inclined to the right; if the units of product were thus abandoned, they would then be transported to the packaging machine irregularly and moreover imperfections would occur in the packaged package.

Pour remédier à ces inconvénients, il est avantageusement prévu de remplacer en partie les guides (15) par des bandes (25) correspondantes, fermées en anneaux, avec la branche supérieure curviligne et coplanaire avec les guides restantes (15) et avec mouvement concordant avec celui de la roue (10), mais avec une vitesse légèrement supérieure à celle que la roue possède en correspondance de la courbe d'appui des unités de produit. De cette manière, le pied de chaque unité de produit du paquet (12) en formation et de ceux déjà terminés est poussé vers l'avant et contre la palette (11) correspondante qui précède le paquet (12) de manière que chaque unité se maintient correctement perpendiculaire à la bande (25) et ainsi jusqu'à ce son dépôt sur le plan d'évacuation (16).To overcome these drawbacks, it is advantageously planned to partially replace the guides (15) with corresponding bands (25), closed in rings, with the curvilinear upper branch and coplanar with the remaining guides (15) and with movement concordant with that of the wheel (10), but with a speed slightly higher than that which the wheel has in correspondence with the support curve of the product units. In this way, the foot of each unit of product of the package (12) in formation and those already finished is pushed forward and against the corresponding pallet (11) which precedes the package (12) so that each unit is correctly maintains perpendicular to the strip (25) and thus until it is deposited on the evacuation plane (16).

Claims (8)

  1. Apparatus for accumulating and counting objects of paper (18) (product units), comprising:
    - means for extracting different units produced continuously by a folding machine with a pair of discs (5), rotating integrally with a continuous movement about a horizontal axis, which are provided with a plurality of curvilinear peripheral laminations (6) arranged tangentially, adjacent to one another and partially superimposed in such a way that the space (7) between two consecutive laminae (6) of each disc is designed to receive a product unit, the same product unit this being supported by the lamina of one disc and that of the other;
    - means (10) for separating product units into packages of the same number, positioned between the two discs (5);
    - transport means (9) for the packages (12) of finished product units, positioned after the aforementioned separating means (10), these transport means comprising a mobile discharge surface (9) conveying the packages (12) to a packing machine; characterised by the fact that the separating means consist of a wheel (10) having a horizontal axis and provided with a plurality of peripheral blades (11) positioned radially which are angularly equidistant and which in conjunction with the wheel (10) delimit successive spaces accommodating the packages (12) to be formed, each package (12) being formed on the blades (11) and part of the circumference of the wheel, the said wheel rotating between the two aforementioned discs and in the same direction as these latter with a variable movement in such a way that one blade (11) after another inserts itself between the last unit of a finished package (12) of product units and the subsequent product unit, the discharge surface being connected to a chain (13) which performs an intermittent movement and which is fitted with a number of equidistant pairs of prongs (17) positioned in such a way as to intercept the finished package (12) by its rear part and push it as far as the packing machine.
