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 units of product which advance on a pair of discs provided with retaining slots which cooperate with separating pallets positioned inside the two discs are continuously counted and accumulated at the point of unloading. 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-up disks and to arrange them in packages, according to programmable values, use is generally made of horizontal reception and evacuation planes cooperating in various ways with movable extraction bars. These are high cost systems which do not allow rapid variability in the production programs because, to predispose a diversification of operation, it is necessary to replace their parts.

L'invention réalise un dispositif de conception nouvelle qui effectue en continu le prélèvement des unités de produit par une paire de disques de prélèvement, permet l'accumulation de manière horizontale ou verticale sur les points de comptage, permet la séparation de deux paquets au moyens de palettes de séparation lorsqu'on atteint le nombre désiré d'unités de produit, effectue l'extraction au moyen d'une chaîne de transport des paquets ainsi formés et permet l'envoi de manière continue à la machine empaqueteuse.The invention provides a device of new design which continuously performs the removal of the units of product by a pair of discs. sampling, allows horizontal or vertical accumulation on the counting points, allows the separation of two packages by means of separation pallets when the desired number of product units is reached, carries out the extraction by means of a chain for transporting the packages thus formed and enables them to be sent continuously to the packaging machine.

Une des particularités essentielles de l'invention est constituée par l'idée inventive de 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 vitesse constante jusqu'à la dernière unité de produit d'un paquet déterminé; dans cette position, elles sont soumises à une brusque augmentation de vitesse de sorte que 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.One of the essential features of the invention is constituted by the inventive idea of carrying 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 constant speed until the last unit of product in a given package; in this position, they are subjected to a sudden increase in speed so that the separation pallet is introduced between the last unit provided for the pack formed and the first unit of the pack in formation, thus successively determining the separation of the pack 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 ratio of rotation between the sampling discs and the support wheel of the separation pallets, it is possible to form packages of different numbers of units in order to adapt the device to the 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 formed adherent 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 in a uniform distribution and in superposition partial, a condition which makes it possible to reduce the speed of progression. Thus used, the units products 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 position of alignment 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 the 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 reception 9 of the packets formed 12 and transport the product to the packaging machine.

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 lamellae 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). We will thus obtain 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 by advancing the receiving plane 16 where the projecting elements 17 of the plane 16 reception and pushed by transport chains will sequentially free the reception and evacuation plan 16 and 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.

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 increases 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 which make up the package (12), the angular distance between two consecutive pallets is greater than that of the wheel in 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 product units 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 remedy these drawbacks, it is advantageously provided for to partially replace the guides (15) by corresponding bands (25), closed in rings, with the curvilinear upper branch and coplanar with the remaining guides (15) and with movement corresponding to 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).
