Abstract

The product dispenser consists of at least one screw (6, 7) with a substantially horizontal axis capable of being driven in rotation one revolution at a time so as to cause products placed between successive turns of the screw to be advanced one by one. The device also includes at least two elongated supports (10, 11) extending roughly parallel to the axis of the screw at such a height that the products placed between the turns of the screw are held by the supports and do not rest on the screw, thus providing for the advance of the products. Application especially to the automatic dispensing of relatively heavy and/or bulky products with shapes in the form of cylinders, parallelepipeds, etc. or contained in packaging with such shapes. <IMAGE>

Description

La présente invention se rapporte à un dispositif de distribution de produits comprenant au moins une hélice ou vis d'axe sensiblement horizontal susceptible d'être entraînée en rotation tour par tour pour distribuer un à un, à l'une de ses extrémités, les produits placés entre les spires consécutives de la vis.The present invention relates to a product distribution device comprising at least one helix or screw with a substantially horizontal axis capable of being rotated in turn to distribute one by one, at one of its ends, the products placed between the consecutive turns of the screw.

Des dispositifs de ce type sont utilisés dans des distributeurs automatiques de produits divers, par exemple de confiseries et de chocolats. Dans ces distributeurs connus, les produits sont placés entre les spires consécutives d'une vis (ou de plusieurs vis parallèles) en fil métallique, disposée(s) sur le fond horizontal d'un tiroir qui peut être retiré du distributeur pour permettre le rechargement de la vis en produits. Les produits reposent donc sur les les spires de la vis, ce qui provoque, lors de la rotation de la vis, un frottement entre les produits et la vis. Il est donc nécessaire de prévoir, pour l'entraînement de la vis, un moteur ayant une puissance tenant compte de ce frottement.Devices of this type are used in automatic dispensers for various products, for example confectionery and chocolates. In these known dispensers, the products are placed between the consecutive turns of a screw (or several parallel screws) made of metal wire, arranged on the horizontal bottom of a drawer which can be removed from the dispenser to allow reloading. of the screw into products. The products therefore rest on the turns of the screw, which causes, during the rotation of the screw, friction between the products and the screw. It is therefore necessary to provide, for driving the screw, a motor having a power which takes account of this friction.

Le brevet US 3 344 953 (Krakauer) et la demande de brevet français 2 266 231 (Rowe) décrivent des dispositifs de ce type dans lesquels chaque vis est munie, à l'intérieur des spires,d'éléments longitudinaux de support et de guidage pour les produits entraînés par les vis. Une seule vis, maintenue par son élément de support interne, est prévue pour chaque groupe de produits, guidés en outre par deux parois latérales.US Patent 3,344,953 (Krakauer) and French Patent Application 2,266,231 (Rowe) describe devices of this type in which each screw is provided, inside the turns, with longitudinal elements support and guide for products driven by the screws. A single screw, held by its internal support element, is provided for each group of products, further guided by two side walls.

Dans le brevet US 3 883 039 (Wittern) chaque vis est supportée à l'intérieur d'une sorte de gouttière longitudinale dont les rebords servent de support et de guidage au groupe de produits que véhicule la vis.In US Patent 3,883,039 (Wittern) each screw is supported inside a kind of longitudinal gutter whose edges serve as support and guide to the group of products that the screw carries.

Tous ces appareils connus sont adaptés à des produits légers et peu volumineux.All these known devices are suitable for light and not very bulky products.

Selon le poids et/ou la nature et/ou la consistance des produits à distribuer, ces distributeurs connus ne donnent pas toujours satisfaction, dans la mesure où ils impliquent l'utilisation de moteurs d'entraînement trop puissants et/ou provoquent une déformation, voire un endommagement ou un blocage des produits.Depending on the weight and / or the nature and / or the consistency of the products to be dispensed, these known dispensers are not always satisfactory, insofar as they involve the use of excessively powerful drive motors and / or cause deformation, or even damage or blockage of the products.

La présente invention a pour objet un dispositif de distribution du type à vis, permettant une distribution fiable même de produits dont le poids et/ou la nature et/ou la consistance posent des problèmes sur les dispositifs connus.The present invention relates to a screw type distribution device, allowing reliable distribution even of products whose weight and / or nature and / or consistency pose problems on known devices.

En particulier, l'invention a pour objet un tel dispositif de distribution à vis qui soit adapté à des produits lourds et volumineux, notamment des produits cylindriques allongés.In particular, the invention relates to such a screw dispensing device which is suitable for heavy and bulky products, in particular elongated cylindrical products.

Le dispositif conforme à l'invention de distribution de produits par entraînement d'une hélice ou vis d'axe sensiblement horizontal, susceptible d'être entraînée en rotation tour par tour pour faire avancer les produits placés entre les spires consécutives de la vis, les produits étant guidés par un support allongé s'étendant de façon sensiblement parallèle à l'axe de la vis, comprend deux vis parallèles et au moins deux supports placés à l'extérieur des spires des vis et s'étendant jusqu'à une hauteur telle qu'un produit ne soit pratiquement en contact qu'avec la portion supérieure des spires des deux vis.The device according to the invention for distributing products by driving a propeller or screw with a substantially horizontal axis, capable of being driven in rotation turn by turn to advance the products placed between the consecutive turns of the screw, the products being guided by an elongated support extending substantially parallel to the axis of the screw, comprises two parallel screws and at least two supports placed outside the turns of the screws and extending to a height such that a product is practically in contact only with the upper portion of the turns of the two screws.

Les deux fonctions d'avancement et de support des produits étant séparées, il est possible de réaliser chacun des éléments remplissant l'une de ces fonctions, à savoir les vis, d'une part, et les supports, d'autre part, de manière qu'ils puissent assumer de façon optimale leur fonction, compte tenu du produit à distribuer.The two advancement and product support functions being separate, it is possible to produce each of the elements fulfilling one of these functions, namely the screws, on the one hand, and the supports, on the other hand, of so that they can optimally assume their function, taking into account the product to be distributed.

Cette séparation des deux fonctions présente des avantages particuliers en cas de distribution de produits susceptibles de rouler (produits cylindriques ou ayant d'autres formes de révolution), dans la mesure où ces produits cylindriques, reposant sur les supports, peuvent rouler, c'est-à-dire être avancés pratiquement sans frottement sur ces supports. Cependant, cette séparation des deux fonctions est également avantageuse pour des produits non roulants qui sont avancés par glissement sur les supports. En effet, ces supports peuvent être conçus pour réduire à une valeur minimale le frottement qui se produit lors du glissement des produits sur les supports, par exemple grâce au fait que les supports présentent un profil et/ou sont réalisés en un matériau ou garnis d'un matériau réduisant au maximum le frottement entre les produits et les supports.This separation of the two functions has particular advantages in the case of distribution of products liable to roll (cylindrical products or having other forms of revolution), insofar as these cylindrical products, resting on the supports, can roll, ie to be advanced practically without friction on these supports. However, this separation of the two functions is also advantageous for non-rolling products which are advanced by sliding on the supports. Indeed, these supports can be designed to reduce to a minimum value the friction which occurs when the products slide on the supports, for example thanks to the fact that the supports have a profile and / or are made of a material or lined with '' a material that minimizes the friction between products and supports.

Les produits n'étant en contact qu'avec la partie supérieure des spires, le frottement est réduit, ce qui permet de distribuer des produits lourds et volumineux sans augmenter sensiblement la puissance des moteurs d'entraînement des vis.Since the products are only in contact with the upper part of the turns, friction is reduced, which makes it possible to distribute heavy and bulky products without significantly increasing the power of the screw drive motors.

Dans un mode de réalisation préféré, le dispositif de distribution comprend deux vis et deux supports disposés entre les deux vis.In a preferred embodiment, the dispensing device comprises two screws and two supports arranged between the two screws.

Suivant une variante, le dispositif peut comprendre deux vis et trois supports, à savoir un support disposé entre les deux vis et deux supports disposés de part et d'autre des deux vis.According to a variant, the device can comprise two screws and three supports, namely a support arranged between the two screws and two supports arranged on either side of the two screws.

Le sens du pas et le sens de la rotation des deux vis sont de préférence tels que les deux vis aient tendance à s'écarter l'une de l'autre, lors de leur rotation. Les deux vis n'ont donc pas besoin d'être maintenues ou guidées et elles ne risquent pas d'entrer en contact, ce qu'il convient bien entendu d'empêcher absolument.The direction of the pitch and the direction of rotation of the two screws are preferably such that the two screws tend to move away from one another, during their rotation. The two screws therefore do not need to be held or guided and they do not risk coming into contact, which should of course be absolutely prevented.

Le pas des vis est en outre, de préférence, supérieur à leur diamètre, en particulier de l'ordre de deux fois le diamètre. Ainsi, des objets volumineux peuvent être acceptés enter les spires et le déplacement latéral des vis reste limité.The pitch of the screws is also preferably greater than their diameter, in particular of the order of twice the diameter. Thus, bulky objects can be accepted between the turns and the lateral movement of the screws remains limited.

En se référant aux dessins annexés, on va décrire ci-après, plus en détail, plusieurs modes de réalisation illustratifs et non limitatifs d'un dispositif de distribution conforme à l'invention; sur les dessins :

  • la figure 1 est une vue en perspective d'un tiroir de distributeur automatique équipé d'un dispositif de distribution à deux vis et à deux supports;
  • la figure 2 est une vue du dispositif de la figure 1 prise dans le sens de la flèche II;
  • la figure 3 est une vue correspondant à celle de la figure 2 d'un autre mode de réalisation du dispositif conforme à l'invention; et
  • la figure 4 est une vue en coupe agrandie selon IV-IV de la figure 2.
Referring to the accompanying drawings, there will be described below, in more detail, several illustrative and non-limiting embodiments of a dispensing device according to the invention; on the drawings:
  • Figure 1 is a perspective view of an automatic dispenser drawer equipped with a dispensing device with two screws and two supports;
  • Figure 2 is a view of the device of Figure 1 taken in the direction of arrow II;
  • Figure 3 is a view corresponding to that of Figure 2 of another embodiment of the device according to the invention; and
  • FIG. 4 is an enlarged sectional view along line IV-IV of FIG. 2.

Selon la figure 1, un tiroir 1 d'un distributeur automatique de produits est formé d'un fond horizontal 2, d'une paroi verticale arrière 3 et de deux parois latérales verticales 4 et 5. A l'extrémité avant, le tiroir est ouvert, c'est-à-dire ne comporte pas de paroi verticale.According to FIG. 1, a drawer 1 of an automatic product dispenser is formed by a horizontal bottom 2, a rear vertical wall 3 and two vertical side walls 4 and 5. At the front end, the drawer is open, that is to say has no vertical wall.

Sur le tiroir 1, sont disposées deux hélices ou vis 6,7 s'étendant au-dessus du fond 2, chacune à proximité de l'une des parois latérales 4,5. Les vis 6,7 qui sont constituées par exemple de fil métallique et présentent un pas (distance entre deux spires consécutives) adapté à l'épaisseur des produits à distribuer, s'étendent depuis l'extrémité arrière du tiroir 1 (paroi arrière 3) jusqu'au bord avant 8 et même de préférence quelque peu au-delà du bord avant 8 du tiroir 1. L'extrémité opposée de chaque vis 6,7 traverse un trou 9 de la paroi arrière 3 en vue de l'entraînement en rotation de la vis 6,7 par un système d'entraînement, de préférence un motoréducteur à deux sorties entraînant simultanément les deux vis 6,7.On the slide 1, two propellers or screws 6,7 are arranged extending above the bottom 2, each near one of the side walls 4,5. The screws 6,7 which consist for example of metallic wire and have a pitch (distance between two consecutive turns) adapted to the thickness of the products to be dispensed, extend from the rear end of the drawer 1 (rear wall 3) up to the front edge 8 and even preferably somewhat beyond the front edge 8 of the drawer 1. The opposite end of each screw 6,7 passes through a hole 9 in the rear wall 3 for the purpose of driving in rotation of the screw 6.7 by a drive system, preferably a gearmotor with two outputs simultaneously driving the two screws 6.7.

Entre les deux vis 6,7, le fond 2 du tiroir 1 porte deux supports allongés 10,11 en forme de baguette plate, s'étendant sur toute la profondeur du tiroir 1, le long des deux vis 6,7.Between the two screws 6,7, the bottom 2 of the drawer 1 carries two elongated supports 10,11 in the form of a flat rod, extending over the entire depth of the drawer 1, along the two screws 6,7.

Comme le montre la figure 2, la hauteur des supports 10,11 est telle que les produits 12 placés entre les spires consécutives des deux vis 6,7 soient soutenus par les supports 10,11 et ne reposent pas sur les vis 6,7. Les produits 12 sont en contact uniquement avec la moitié supérieure des spires des vis 6 et 7 comme on le voit sur les figures 2 et 4.As shown in Figure 2, the height of the supports 10,11 is such that the products 12 placed between the consecutive turns of the two screws 6,7 are supported by the supports 10,11 and do not rest on the screws 6,7. The products 12 are in contact only with the upper half of the turns of the screws 6 and 7 as seen in FIGS. 2 and 4.

De ce fait, les vis 6,7 servent uniquement à faire avancer, mais non pas à supporter les produits 12, et le frottement est notablement réduit.Therefore, the screws 6,7 serve only to advance, but not to support the products 12, and the friction is significantly reduced.

Les supports 10 et 11 sont disposés à l'extérieur des spires des vis 6 et 7, entre ces dernières.The supports 10 and 11 are arranged outside the turns of the screws 6 and 7, between the latter.

La vis 6 présente un pas à gauche et est entraînée dans le sens inverse des aiguilles d'une montre selon la flèche 6a. La vis 7 présente un pas à droite et est entraînée dans le sens des aiguilles d'une montre selon la flèche 7a. Il en résulte que, lors de leur rotation simultanée faisant avancer le produit 12, les deux vis 6 et 7 qui reposent librement sur le fond 2, ont tendance à s'écarter l'une de l'autre. Ce mouvement faible constitue une sécurité du dispositif de l'invention, en particulier dans le cas où les deux supports 10 et 11 seraient placés non pas entre les vis 6 et 7 mais de l'autre côté, à l'extérieur des vis 6 et 7, laissant libre l'espace situé entre les vis 6 et 7.Screw 6 has a pitch to the left and is driven counter-clockwise shows according to arrow 6a. The screw 7 has a pitch to the right and is driven clockwise according to arrow 7a. It follows that, during their simultaneous rotation advancing the product 12, the two screws 6 and 7 which rest freely on the bottom 2, tend to move away from one another. This weak movement constitutes a security of the device of the invention, in particular in the case where the two supports 10 and 11 are placed not between the screws 6 and 7 but on the other side, outside the screws 6 and 7, leaving the space between the screws 6 and 7 free.

On comprend, en effet, qu'il convient d'éviter absolument tout contact entre les vis 6 et 7, contact qui pourrait alors se produire si lesdites vis avaient tendance à se rapprocher.It is understood, in fact, that absolutely any contact between the screws 6 and 7 should be avoided, contact which could then occur if the said screws tended to approach.

Selon la figure 3, un tiroir 1 d'un distributeur automatique comprend deux vis 13 et 14 espacées et trois supports 15,16,17, à savoir un support 15 s'étendant en position médiane entre les deux vis 13,14 et deux supports 16,17 disposés de part et d'autre des deux vis 13,14. A part cette modification, le dispositif est identique à celui de la figure 2.According to FIG. 3, a drawer 1 of an automatic dispenser comprises two spaced apart screws 13 and 14 and three supports 15,16,17, namely a support 15 extending in the middle position between the two screws 13,14 and two supports 16.17 arranged on either side of the two screws 13.14. Apart from this modification, the device is identical to that of FIG. 2.

Sur la figure 4, on voit que le produit 12, de forme cylindrique, est poussé vers la gauche par une spire arrière de la vis 6 en entrant en contact avec une partie supérieure de celle-ci. Le pas de la vis 6 est de l'ordre de deux fois son diamètre, de sorte que le produit 12 n'entre pas en contact avec la spire avant de la vis 6, compte tenu du fait que le produit 12 est supporté par les supports 10 et 11 environ au niveau du plan médian des vis 6 et 7.In Figure 4, we see that the product 12, of cylindrical shape, is pushed to the left by a rear turn of the screw 6 by coming into contact with an upper part thereof. The pitch of the screw 6 is of the order of twice its diameter, so that the product 12 does not come into contact with the turn before the screw 6, taking into account that the product 12 is supported by the supports 10 and 11 approximately at the median plane of the screws 6 and 7.

On a représenté sur la figure 4 en pointillés un autre produit 18 de section rectangulaire qui peut être poussé par la vis 6 en glissant sur les supports 10 et 11 alors que le produit 12 cylindrique peut rouler sur les supports 10 et 11.Another dashed product 18 is shown in FIG. 4 with a rectangular section which can be pushed by the screw 6 by sliding on the supports 10 and 11 while the cylindrical product 12 can roll. on supports 10 and 11.

Les vis 6,7,13,14, peuvent être constituées de fil métallique d'une épaisseur qui est fonction du poids des produits à distribuer et du nombre de produits susceptibles d'être distribués par chaque vis. Le pas des vis est fonction de l'épaisseur des produits à distribuer, de manière que chaque produit puisse être placé entre deux spires consécutives. Le pas des vis est cependant de préférence supérieur à leur diamètre, notamment de l'ordre de deux fois le diamètre, ce qui permet de recevoir des objets volumineux et de limiter le frottement.The screws 6,7,13,14, can be made of metal wire with a thickness which is a function of the weight of the products to be distributed and the number of products capable of being distributed by each screw. The pitch of the screws depends on the thickness of the products to be dispensed, so that each product can be placed between two consecutive turns. The pitch of the screws is however preferably greater than their diameter, in particular of the order of twice the diameter, which makes it possible to receive bulky objects and to limit friction.

Les supports 10,11,15,16,17 peuvent être constitués par exemple par des plats de tôle, comme représenté sur la figure 1, notamment lorsque les produits à distribuer sont de forme cylindrique et peuvent rouler sur les supports. Il est cependant possible également de donner aux supports des profils différents et/ou de les réaliser en des matériaux différents, notamment des matériaux à faible coefficient de frottement, ou de les garnir de tels matériaux, dans le cas où les produits à distribuer ne sont pas cylindriques et glissent donc sur les supports lors de leur avancement par les vis.The supports 10, 11, 15, 16, 17 can be constituted for example by sheet metal plates, as shown in FIG. 1, in particular when the products to be dispensed are of cylindrical shape and can roll on the supports. It is however also possible to give the supports different profiles and / or to produce them in different materials, in particular materials with a low coefficient of friction, or to garnish them with such materials, in the case where the products to be dispensed are not not cylindrical and therefore slide on the supports during their advancement by the screws.

L'invention peut être avantageusement utilisée pour distribuer des produits lourds et volumineux, en particulier des rouleaux cylindriques d'emballage pouvant contenir des produits divers et notamment des vêtements.The invention can advantageously be used to distribute heavy and bulky products, in particular cylindrical packaging rolls which may contain various products and in particular clothing.
