Definitions

  • the present invention relates to a star conveyor for transferring containers, of the type able to be associated to a container receiving station equipped with means for gripping said containers.
  • the star comprises at least a discoidal element movable by rotation and provided with a plurality of peripheral sectors defining an equal number of recesses so shaped as to house individual containers to be transferred and at least a guide, external to the discoidal element, positioned peripherally thereto, to hold the containers in position inside the recesses during their transfer to the receiving station.
  • Said star is provided with at least a pair of terminal guides to convey the containers towards the gripping means, one of said terminal guides being positioned in correspondence with at least a peripheral sector and the other one being substantially aligned with the external guide.
  • star conveyors are used in bottling plants, in particular to feed containers towards automatic rotary machines, such as filler machines, rinsing machines, labelling machines or to transfer containers to a linear conveyor or to non rotary automatic machines.
  • Star conveyors are known, comprising a rotating body peripherally provided with a plurality of recesses for housing and transporting the containers, retained externally by a guide which prevents them from egressing the conveyor.
  • current star conveyors are provided with a plurality of peripheral recesses that house gripping means, typically pairs of jaws commanded by cams, for retaining containers.
  • current star conveyors are provided with a disk whereon are obtained peripheral recesses for conveying containers, one for each recess, with the aid of an external guide and of a lower support platform whereon the containers bear and are driven.
  • star conveyors are associated with rotary machines, they are positioned in such a way that the recesses, during the transfer of the containers, geometrically coincide with gripping means present on a carrousel of said machines.
  • the pitch line of the transferring star crosses, for a certain angle of rotation, the pitch line of the carrousel, thereby enabling the containers to be transferred without geometric interference.
  • said star containers are used to transfer containers to linear machines or conveyors, it is not possible to obtain the geometric coincidence between the recesses and the gripping means present on said machine or conveyor.
  • sliding guides are required to convey the containers, once they are released by the recesses, to the gripping means, forcing them to enter therein.
  • the star conveyors briefly described above, when they are used in combination with linear machines or conveyors have the important drawback of causing the erroneous positioning of the containers during the transfer thereof from the recesses to the gripping means.
  • the containers frequently and randomly get stuck between the sliding guides and the gripping means, causing them to be damaged and even to be broken down, due to the simultaneous crushing of said containers against said gripping means brought about by the rotation of the star.
  • the aim of the present invention is to eliminate the aforesaid drawbacks making available a star conveyor for transferring containers, which is able to be associated to linear machines or other conveyors and to prevent damage to the gripping means present on said machines or conveyor due to anomalous bulks caused by the erroneous positioning of the containers.
  • the star conveyor for transferring containers of the present invention, which is characterised by the contents of the claims set out below and in particular in that the terminal guide positioned in correspondence with at least a peripheral sectors and the peripheral sectors themselves are so shaped as to be retractable in a direction that is substantially radial to the discoidal element, by effect of forces exerted by any erroneous positions of a container which hinder its transfer to the gripping means of the receiving station.
  • the terminal guide positioned in correspondence with at least a peripheral sectors and the peripheral sectors themselves are so shaped as to be retractable in a direction that is substantially radial to the discoidal element, by effect of forces exerted by any erroneous positions of a container which hinder its transfer to the gripping means of the receiving station.
