Patent number: 6003653Abstract: A "fruit cup" (1) which is shaped to receive articles, for example single pieces of fruit of produce such as apples. The articles rest in a space on a support between the back plate (7) of a "U" shaped bracket and a rotatable bow-tie roller (2) positioned between the arms (4, 5) of the bracket. The support sits on a mounting to which it is coupled while being allowed limited relative movement therebetween. The relative movement between the support and the mounting allows the support to be tilted, lifting the roller (2), enabling it to be rotated to ensure that the "fruit cup" (1) contains only one article. The support is also able to be tipped to either side, to discharge the article contained therein, and to later be repositioned atop the mounting. In use, the base (13, 14) of the mounting is attached to an endless chain conveyor so that a number of "fruit cups" form an endless circuit in an article grading/packaging/sorting system which may have a number of adjacent circuits.Type: GrantFiled: July 27, 1995Date of Patent: December 21, 1999Assignee: Horticultural Automation LimitedInventors: Hamish Nigel Alexander Kennedy, Gavin Brian Reeve, Peter Samuel Short, Philip William Poore
