Abstract
The process includes an initial phase in which pieces of fruit in a line are lifted by suction and the line of fruit is then transferred to the packing case with one piece of fruit situated in the central zone of the line being displaced angularly and the remainder of the fruit either side of this central piece being displaced towards the center of the line prior to the entry of the line of fruit into the case. After entry, the pieces of fruit resume their initial position and are deposited in the case and the suction is discontinued. The machinery includes a mechanism having a plurality of vacuum operated suction pads of which the central suction pad can be moved angularly and the remainder have the means to be displaced laterally.
Claims11
A process for the automated placing of fruit in packing cases comprising the steps of:
- (a) applying suction to a plurality of pieces of fruit arranged in a line equivalent to a quantity required to fill a corresponding line in a case that is to be filled with fruit and in the identical relative positions with respect to each other;
- (b) carrying said line of pieces of fruit first in an ascending vertical trajectory followed by a curvilinear path and a further vertical descending path towards the packing case
- (c) angularly displacing one piece of fruit situated in a central zone of said line of pieces of fruit;
- (d) linearly displacing the other pieces of fruit on either side of the angularly displaced piece of fruit toward the central zone such that the length of the line of fruit is reduced by an amount that allows the fruit to enter the packing case opening;
- (e) depositing the fruit within the case in their initial linear arrangement;
- and
- (f) ceasing the suction operation once the fruit has been placed in the case.
An apparatus for automatically placing fruit in packing cases comprising:
- means for individually applying a gripping force to each of a plurality of pieces of fruit, said plurality of pieces of fruit being arranged linearly and in predetermined quantities;
- means for carrying said pieces of fruit first in an ascending vertical trajectory, then in a curvilinear path, and then in a vertical descending trajectory towards said packing case;
- means for angularly displacing one piece of fruit in said linear arrangement with respect to the remaining pieces of fruit;
- means for linearly displacing the remaining pieces of fruit and filling a gap left by the angularly displaced piece of fruit, wherein the length of said linearly arranged pieces of fruit is reduced by an amount equal to that of said angularly displaced piece of fruit;
- means for depositing said fruit within said packing case in the initial linear arrangement;
- and
- means for releasing said individually applied gripping force on each of said plurality of pieces of fruit.
An apparatus for automatically placing fruit in packing cases according to claim 9, wherein said means for individually applying a gripping force includes a plurality of suction pads connected to a transverse beam suspended directly from an articulated arm, and further including two shorter beams located below the transverse suspended beam and joined thereto by at least two pairs of connecting members forming two articulated parallelograms having lower members for supporting the suction pads, and an articulated member positioned between the two parallelograms from which an independent suction pad is rotatably supported with respect to the axis of the transverse suspended beam and being displaceable on a plane perpendicular to the plane of the parallelograms.
