Definitions

  • the present invention relates to a metal chain for chain conveyors, of the type indicated in the pre-characterising part of the main claim.
  • a piece of metal chain in accordance with the pre-characterising part of the main claim is shown in the accompanying Figures 1A and 1 B.
  • All known chains of the aforeindicated type present a gap between the opposing sides of one link and the preceding link. This gap is indicated by the letter G in Figures 1A and 1 B, and in the chains of best construction is currently between 1.5 and 2.8 mm. Gaps of 1.5 mm can however only be obtained in chains having large radii of curvature in their movement reversal parts.
  • An object of the present invention is to provide a metal chain in accordance with the pre-characterising part of the main claim which solves the aforestated technical problem, and in particular presents a surface between a link and the immediately adjacent link which when viewed from above is free of gaps, and hence improves the conveying of products by not damaging their base; a further object is to provide a chain which is of more reliable and easier assembly.
  • Figures 3A and 3B are enlarged schematic sections taken respectively on the lines A-A and B-B of Figure 1B.
  • each link comprising a substantially plate-like metal body 1A defining a support surface 2 for the products to be conveyed, said body 1A presenting on a rear side 3 (with respect to the direction of advancement of the chain, indicated by the arrow F in Figure 2A) at least one first element 4 for connecting a link to the preceding link, said first connection element 4 comprising a first portion 4A substantially coplanar with said support surface 2, and a second portion 4B provided below said support surface 2, said two portions being shaped to house a part of a pin 6 connecting together two successive links of said chain.
  • the body 1A presents in its front side 7, which is parallel to its rear side 3, at least one recessed seat 7A for housing the first portion 4A of the first connection element 4, and presents below the support surface 2 at least one connection counter-element 8 presenting at least two further portions 8A, each shaped to house a part of a pin 6 for connecting the links together, it also presenting between said two further portions the second portion 4B of the connection element for another link of the chain.
  • the surfaces defining the rear side 3 and front side 7 of the body of said links when connected together are mutually rounded, in such a manner as to form a chain with a support surface which when viewed from above appears substantially continuous, without vertical slits between the opposing parts of the sides of a link and those of the immediately succeeding and preceding links.
  • rear side 3 and front side 7 of a link which are immediately adjacent respectively to the respective front side 7 of a preceding link and to the rear side 3 of a successive link of the chain are rounded and shaped such that the slit created between said sides of the links is no longer vertical as in the known art, but extends as an arc such that the products conveyed by the chain encounter along the entire extension of the support surface of the chain a surface which, when viewed from above, appears closed and free of gaps.
  • the upper edge B1 ( Figure 3B) of the side of a link and the respective lower edge B2 of the immediately preceding or succeeding link appear superposed one on the other as shown in particular in Figures 3A and 3B.
  • the upper edge B1 substantially coplanar with the support surface 2 ( Figure 3B) 1 of the rear side (with respect to the chain advancement direction) 3 of a link M1 is superposed on the respective lower edge B2 of the front side 7 of the immediately succeeding (with respect to the chain advancement direction F) link M2.
  • the radius of curvature R2 of the rounded lateral surface of the rear side 3 of a link M1 ( Figure 3B) is greater than the radius of curvature R1 of the corresponding rounded lateral surface 7 of the immediately succeeding link M2, so that, if for any reason the conveyed products slide along the links (this can for example be due to a narrowing of the conveyor), they encounter a facilitation surface for their passage from one link to the next.
  • the side 10 ( Figures 3A and 2B) of the recessed seat 7A of the front side 7 of a link is also rounded and is shaped such that the upper edge B3, substantially coplanar with the support surface 2, of said side 10, is superposed on the point of vertical tangency B4 of said curved portion 4B.
  • the connection element 4 and the relative counter-elements 8A are constructed in one piece with the body of the chain.
  • a pressing process is used to form the curved surfaces along the adjacent sides of the links.
  • the link can be formed of any metal suitable for the purpose, for example of carbon steel (for example of C45 type), of standard steel (for example of AISI 430 type), or of austenitic steel (for example of AISI 304 type).
  • carbon steel for example of C45 type
  • standard steel for example of AISI 430 type
  • austenitic steel for example of AISI 304 type.
  • the surface 2 can also be provided with usual treatments or components for improving product entrainment.

Abstract

La présente invention concerne une chaîne en métal pour convoyeurs à chaîne, du type comprenant une pluralité de maillons en métal (1), chaque maillon comprenant un corps en métal sensiblement de type plaque (1A) définissant une surface de support plate (2) pour les produits à transporter, ledit corps (1A) présentant sur un premier côté (3) au moins un premier élément (4) pour raccorder un maillon au maillon précédent, et présentant sur un second côté (7), parallèle au premier, au moins un contre-élément de raccord (8A), les maillons de chaîne (1) étant raccordés en fixant de manière amovible l’élément de raccord d’un maillon aux contre-éléments d’un maillon adjacent, lesdits maillons ayant une forme telle que le second côté (7) et le premier côté (3) d’un premier maillon sont respectivement adjacents au premier côté (3) et au second côté (7) de deux maillons immédiatement adjacents au dit premier maillon, ces surfaces définissant lesdits côtés (7, 3) du corps (1A) desdits maillons (1) ayant une forme telle que, avec la chaîne assemblée, la surface desdits côtés (7, 3) d’un maillon est au moins partiellement superposée à la surface du côté adjacent correspondant (3, 7) du maillon adjacent, de sorte que les produits transportés par la chaîne rencontrent toujours le long de la chaîne une surface de support (2) qui, lorsqu’elle est observée d’en haut est fermée sur lesdits côtés adjacents (7, 3) des maillons adjacents de la chaîne.
