Definitions

  • This invention relates to a conveyor system, and more particularly, but not exclusively, a conveyor system for a baking oven.
  • the conveyor system may also be used in a prover for proving of bakery products and in other environments not associated with the bakery industry.
  • the invention relates to a continuous system whereby trays, pans, boards and like devices, and hereinafter generally referred to as trays, of product, such as bakery products, to be baked are continuously fed onto the conveyor system and at the same time are continuously discharged from the system.
  • trays of product may be loaded onto a continuous conveyor system externally of the prover and carried by the conveyor syste into the prover to move therethrough to an exit therefrom, whereafter the trays are removed.
  • the length of the conveyor system within the prover and the speed at which the conveyor moves determines the proving time.
  • the product After the product has been proved, it is transferred to an oven so that the product can be baked.
  • An object of a first aspect of this invention is to provide a conveying system which provides for transfer of product and the conveying of product without substantial buffeting of the product.
  • the invention may be said to reside in a conveying system for conveying a product
  • a continuous product support conveyor defining a conveying path for the product
  • a loading and unloading conveyor means having a first continuous conveyor for supporting a portion of said product and extending from a loading station onto said product support conveyor so as to be supported by the product support conveyor along said conveying path to an unloading station, a second continuous conveyor at said loading station spaced from said first continuous conveyor for supporting a second portion of said product, a third continuous conveyor at said unloading station spaced from said first continuous conveyor for supporting the second portion of the product when the product arrives at the unloading station; wherein, in use, said product is loaded onto said first continuous conveyor and said second continuous conveyor at the loading station so that the product is supported at the first and second portions and is conveyed onto the product support conveyor so that the first portion of the product remains supported on the first continuous conveyor as the first continuous conveyor is supported by the product support conveyor and moves along said conveying path, and with other portions of the product being supported by the product support
  • the conveyor system includes the loading and unloading conveyor having the first, second and third continuous conveyors, the product is smoothly transferred from the loading station onto the product support conveyor for movement along the conveying path so that the product can be treated or processed as is necessary and is smoothly unloaded from the product support conveyor at the unloading station. Since transition from the loading station onto the product support conveyor is smooth there is no buffeting or vibration created wiich could deteriorate the product.
  • the product support conveyor includes a drive system for driving the product support conveyor and a plurality of spaced apart support means extending away from one side of the drive system in cantilever fashion.
  • the first continuous conveyor, second continuous conveyor and third continuous conveyor comprise flexible chain belts.
  • the path traversed by the product support conveyor within said system comprises a first spiral path portion extending vertically upwardly, and at least one further spiral portion extending vertically downwardly, and wherein the said first and further spiral portions are connected to provide the continuous product support conveyor.
  • the preferred conveyor path configured as described above a large portion of the length is contained within the spiral portions of its path and thus the floor area occupied by such portions is significantly less than would be occupied by an equivalent length of a non-spiral configuration.
  • the number of changes of direction at transitions between circular to linear paths is reduced to a minimum, i.e. two such changes in direction for those parts of the conveyor system on which objects reside, and which thus reduces disturbance to, and subsequent disarray of, the objects being conveyed, such as trays supporting the product to be proved and which are supported on the conveyor system.
  • all the supporting structure for the conveyor system can be contained within, and between, the spirals, which once again contributes to reducing the floor area required.

  • a system of the type described above in utilising a constant velocity cam which exerts a push/pull action on the chain drive avoids the need for chain tensioning and due to the continuous sliding engagement between the surfaces of the constant velocity cam and the chain drive members the "polygonal" action normally associated with chain drive sprockets is avoided and the continuity of driving engagement is not effected by any variations in chain pitch which might occur through wear.
  • This aspect of the invention may be said to reside in a conveying system for conveying containers and for automatically closing said containers, said system comprising: a continuous product support conveyor for conveying said containers along a conveying path; closure means supported by said product support conveyor for movement with said product support conveyor above said containers when said containers are conveyed by the product support conveyor; actuating means for selectively moving said closure means from a first position away from said containers wherein said containers are open to a second position wherein said containers are closed by the closure means.

  • said actuating means comprises a movable cam fixed relative to said conveying system and links pivotally coupled to said conveyor system and engaging said arms such that when said cam is moved into an actuating position said links engage said cam as the conveyor moves past said cam to cause the links to pivot relative to the conveying system and move the arms from the first position to the second position.
  • the closure means may comprise a plurality of overlapping plates supported by said arms so as to provide a continuous lid above said conveying system.
  • said conveying system includes closure opening means downstream of said actuating means for moving said closure means from the first position where it closes the containers to a second position in which the containers are open.
  • the closure opening means comprises a cam fixed relative to said conveying means which engages said links to move the links to, in turn, move the arms into their first position.
  • a further aspect of the invention resides in a baking oven for baking a product comprising: a baking chamber containing a conveying system for conveying the product within the enclosure; partitioning means within said baking chamber for partitioning the baking chamber into a plurality of compartments with said conveying system extending through each of said compartments.

Abstract

Un système d'acheminement automatique destiné à un four de boulangerie se compose d'un convoyeur continu supportant des produits (12) disposé en deux tours (15a) et (15b). Une station de chargement L et une station de déchargement U sont installées adjacentes au bas des tours respectivement (15a) et (15b). La station de chargement L est constituée d'un premier convoyeur continu (70) qui est plus étroit que le convoyeur support (12) et s'étend de la station de chargement L jusqu'au convoyeur (12) et à la station de déchargement U. La station de chargement L est également constituée d'un second convoyeur continu (72) qui est espacé du premier convoyeur continu (70) et s'étend jusqu'au-dessous de la spirale inférieure de la tour (15b). Un troisième convoyeur continu (74) est installé à la station de déchargement U à partir du premier convoyeur (70). Le produit placé sur le système d'acheminement est transferé de la station de chargement L au convoyeur continu (12) tout en étant toujours supporté par le premier convoyeur (70) et est transféré du convoyeur continu (12) à la station de déchargement U tout en étant toujours supporté par le premier convoyeur (70). Le transfert de produits depuis une station de chargemnt L à un convoyeur (12) et depuis ledit convoyeur (12) à une station de déchargement U se fait par conséquent sans à-coups. Un bras (84) supporte un élément de couverture (90) qui peut se déplacer de manière à couvrir ou à découvrir de manière sélective les produits soutenus par le convoyeur continu (12). La chambre de cuisson (150) dans laquelle se trouvent les tours (15a) et (15b) peut être cloisonnée par une cloison (180) de façon à ce que ladite chambre (150) soit divisée en compartiments.
