Abstract

The handling equipment uses a chain conveyor to displace mfd. goods etc. on a steeply inclined path without slippage. The path may be straight or may spiral upwards and each link has an upper bearing surface coated with nylon polyamide with a bristle length varying from 0.5 to 5 mm depending on the nature of the goods conveyed. The nylon is applied after sanding and glueing of the relevant face, and by an electrostatic process known as electrostatic flocking. The coefft. of friction of the bristled surface may be such that the inclination of the conveyor is up to three times greater than that of conventional equipment, and the bristles may have shock-absorbant characteristics reducing damage to fragile goods.

Description

La présente invention concerne le domaine de la manutention continue par convoyeurs à chaine. The present invention relates to the field of continuous handling by chain conveyors.

Dans les dispositifs connus de ce genre, une chaîne avec ou sans palette entraînée par un moyen mécanique telque moto réducteur et circulant sur des glissières dans tous les sens du plan horizontal ou d'un plan oblique (la chaine étant articulée) permet de transporter des pièces d'un point à un autre (entrepôt de stockage, alimentation de machines outils ect...). In known devices of this kind, a chain with or without a pallet driven by mechanical means such as a gear motor and circulating on slides in all directions in the horizontal plane or in an oblique plane (the chain being articulated) makes it possible to transport parts from one point to another (storage warehouse, supply of machine tools, etc.).

Le déplacement de cette chaine suivant un tracé hélicoidal permet d'élever ou de descendre les pièces à transpor- ter sur plusieurs niveaux ce qui permet de réaliser un stock tampon en mouvement (éventuellement). The movement of this chain along a helical path allows the pieces to be transported to be raised or lowered on several levels, which makes it possible to create a moving buffer stock (possibly).

La contrainte est la pente de la chaîne qui possède un bon coefficient de frottement, ce qui limite la pente possible sans glissement à 60 maximum suivant les produits convoyés. La transformation selon l'invention permet de remédier à cet inconvénient. The constraint is the slope of the chain which has a good coefficient of friction, which limits the possible slope without slipping to 60 maximum depending on the products conveyed. The transformation according to the invention overcomes this drawback.

Elle consiste en l'application sur la surface supérieure des maillons de la chaine qui reçoit les pièces ou produits à transporter, d'un revêtement par un procédé electro statique constitué de poils synthétiques tels que nylon, polyester ou autres de longueur allant de 0,5 à 5 millimètres suivant les différents cas d'utilisation (procédé d'application existant connu sous le nom de flockage électro statique). It consists in applying on the upper surface of the links of the chain which receives the parts or products to be transported, a coating by an electro static process consisting of synthetic bristles such as nylon, polyester or others of length ranging from 0, 5 to 5 millimeters depending on the different use cases (existing application process known as electro static flocking).

Le revêtement ainsi constitué confère à la chaîne un coefficient d'adhérence important qui permet d'augmenter la pente du convoyeur dans un rapport de trois fois celle pratiquée avec une chaîne non revêtue. The coating thus formed gives the chain a high coefficient of adhesion which makes it possible to increase the slope of the conveyor in a ratio of three times that practiced with an uncoated chain.

Le revêtement jnue également le rôle d'amortisseur en cas de chocs de pièces ou de produits posés brutalement (manuellement ou mécaniquement) sur la chaSne,évitant ainsi toute détérioration des pièces à transporter, ce qui s'applique particulièrement aux produits fragiles dans des domaines tels que bijouterie,verre,optique,électronique, laboratoires,audio- visuel,c'est à dire pour des transports de pièces propres. The coating also acts as a shock absorber in the event of parts or products impacting suddenly (manually or mechanically) on the chain, thus avoiding any deterioration of the parts to be transported, which applies particularly to fragile products in areas such as jewelry, glass, optics, electronics, laboratories, audio-visual, ie for transport of clean parts.

Le procédé s'applique également dans le domaine de 1' agro alimentaire, le revêtement pouvant être de qualité alimentaire donc sans inconvénient.  The process also applies in the field of food processing, the coating being able to be of food grade therefore without disadvantage.

Le revetement ne craint pas l'humidité,le nettoyage est possible même au jet d'eau et la température d'utilisation peut varier de - 200 C à + 650 C, il est anti-statique et anti déflagrant. The coating does not fear humidity, cleaning is possible even with a water jet and the temperature of use can vary from - 200 C to + 650 C, it is anti-static and explosion-proof.

L'augmentation importante de la pente permet une simplification du matériel mis en oeuvre et la fourniture d'un nombre moindre d'élélments ce qui se traduit par un prix de revient moins élevé lorsque la différence de niveau est grande (cas du convoyeur suivant tracé hélicoldal à usage d'ascenseur ou descenseur). De même lorsque le revêtement est usagé il peut être remplacé aprés décapage et nouvelle projection, opération d'un moindre coût que le remplacement de la chaîne. The significant increase in the slope allows a simplification of the material used and the supply of a fewer number of elements which results in a lower cost price when the difference in level is large (case of the conveyor following layout helicoidal for use as an elevator or descender). Similarly when the coating is used it can be replaced after stripping and re-spraying, an operation of lower cost than replacing the chain.

Lorsque les pièces à transporter sont en butée sur un moyen mécanique fixe ou mobile et que la channe est toujours en mouvement (cas du stock tampon) le frottement du revetement sur le dessous des pièces est sans inconvénient vu sa trés grande résistance à l'usure. En effet,la qualité du revêtement est adaptée aux produits à transporter et le revêtement ne modifie en aucun cas les caractéristiques mécaniques,physico-chimique du matériau de base de la channe. When the parts to be transported are in abutment on a fixed or mobile mechanical means and the chain is always in movement (case of the buffer stock) the friction of the coating on the underside of the parts is without disadvantage considering its very high resistance to wear . Indeed, the quality of the coating is adapted to the products to be transported and the coating does not in any way modify the mechanical, physico-chemical characteristics of the base material of the chain.
