Description
π η&ι ,D>ma τηνηι , p\>>n >Λ D>Q* i o riiDiyQ A SYSTEM FOR SORTING OF OBJECTS BY WEIGHT, PARTICULARLY FLOWERS, AND METHOD A SYSTEM FOR SORTING OBJECTS BY WEIGHT, : PARTICULARLY FLOWERS, AND METHOD BACKGROUND OF THE INVENTION The present invention relates to the art of sorting or classifying of objects, and more particularly to sorting of flowers by their weight.
Sorting of flowers is a major requirement in the relevant industry and is presently accomplished manually, namely by placing the flowers on weighting apparatus, reading the scale and accordingly classifying the flowers into groups of different weight. This process is, of course, time-consuming and inefficient.
It is thus the object of the invention to provide a method and a system for automatically sorting flowers in a continuous process according to prerdetermined weight categories.
It is a further object of the present invention to utilize a blowing process for the displacement of the flowers from the weighting device platform into suitable collecting trays or receptacles, SUMMARYiOF THE INVENTION Thus provided according to one aspect of the present invention is a system for sorting objects by weight, particularly flowers, comprising a weighting apparatus onto which the objects are adapted to be placed one by one for weighting, means for converting the weight of the object into. electronic signalsj means for processing the signals to identify an amount of ί · - . weight greater/smaller than a pre-determined value, pressurized air blowing means in juxtaposition with the weighting apparatus, operable.to blow the object off the apparatus in one direction or the opposite direction relative, thereto, and means governed by the processing means for controlling the blowing means depending upon the weight amount being greater or smaller than the pre-determined value.
The weighting apparatus preferably comprise a platform onto which the objects are placed, said blowing means comprise a pair of nozzled tubes extending along both sides of the platform, the pressurized air supplied to each tube being controlled by said control means.
According;to a modified embodiment of the invention, the system further comprises at-least a second weighting apparatus onto which the objects are blown off the first weighting apparatus, the objects being collected by three elongated receptacles, one extending along one side of the first weight apparatus and second and third receptacles extending along opposite sides of the second weighting apparatus, The objects are preferably supplied onto the weighting apparatus platform in a continuous ma ner, e.g., by conveying means. i According to another aspect of the invention there is provided a method of sorting objects by weight, particularly flowers,- comprising the steps of providing an electronic weight apparatus having a top surface, placing the object on the surface for weighting, converting the weight into an electronic signal and processing the signal to actuate pressurized air supply i first blowing means adapted to blow the object off the top surface ir a first direction if the signal represents a weight greater than a pre-determined value, or to second blowing means adapted to blow the object off the top . surface in a second direction if the signal represents a weight less than the pre-determined value.
BRIEF DESCRIPTION OF THE DRAWINGS Further objects and additional advantages of the invention will be appreciated with reference to the ensuing description of preferred embodiments of the invention, given by way of example only, with reference to the j , . , . . . . , , accompanying drawings, wherein, Fig. 1 is a general, schematic, three-dimensional view of a system featuring i j . ■ : . .. . . " '. . , ·■ . . . . · '. the characteristics of the present invention, in a first basic embodiment thereof; Fig. 2 is a schematic representation of the system of Fig. 1 ; Fig. 3 is a further developed embodiment of the system of Fig. 1 ; and Fig. 4 is a still further developed embodiment.
DETAILEDj DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to Figs.1 and 2 there is shown that the system" essentially comprises an electronic weighting apparatus or scale generally denoted A1 , comprising a platform a1_ onto which the processed objects, e.g. flowers a2, are placed for processing.
Further comprised in the system is a pair of trough-like elongated receptacles B1 and B2 extending along, and at a lower level with respect to the I · · weighting apparatus A1. ί ' ' ■ ' .■ . ' ■ ' . · A pair of. nozzled tubes C1 and C2 are installed alongside and at a somewhat elevated level with respect to the platform a of the: apparatus A1. The tubes C1 and C2 are connected to a pressurized air source D, namely a . compressor.
The compressor supplies pressurized air through electrically actuated valve £1 to conduit El leading to tube C ; similarly, conduit E2Jncludes similar valve F2 leading to tube C2 .
The arrangement is such that once a value greater then a pre-determined amount XI is sensed by the computerized unit G., the valve F1_becomes actuated to open the air supply to tube CI , and if the sensed value is less than XI - the other valve F2 will become opened and air will be supplied to nozzled tube C2. The applied air-pressure, as well as other parameters such as the sizes, number, size and/or rate of deployment of the nozzles along the tubes are suitably designed so as to enable the blowing the flower away from the respective tube . . ! . . . ■ - .· . . . & ■ - ·' ■ · . = ·· : ■ ·' ' · : . .
The operation of- the system so far described is thus performed in the following manner.' Flowers (or other objects) are continuously fed to the weighting apparatus A1 , e.g. by conveyor H. (Fig. 2). Each cycle of sorting comprises the * sensing of the flower weight being less or above a pre-determiried weight (X1 ) programmed into the unit G. Accordingly, air jets will be ejected from either one of the tubes C1 or C2 to blow off the flower into either one of the receptacles B2 or B1 , respectively, | Hence, blowing tube C2 will cause the object to fall into -receptacle B1 and vice-versa. > ~ The system!of Fig. 3 exemplifies a first, simple development of the basic -embodiment described above. Hence, the first weighting apparatus AT supplies the sorted flowers either to a receptacle B1 at one side thereof, or to a second weighting apparatus _A2. The weighting apparatus A2 is associated with an · electronic system similar to the one described above with reference to Fig. 1 , to effect the sorting of the objects relative to a value X2, namely that objects weighting more tjien X2 will be supplied to receptacle B3 and those weighting less then X2 will become collected in receptacle B4. The bulk of the flowers will thus be sorted into three groups. .
Fig. 4 is a still further extrapolated embodiment, where a pair of sub-sorting weighting apparatus A2 and A3 are provided, thus sorting the flowers into four groups collected in receptacles B3, B4, B5 and B6., as the case may be.
It is thus seen that the sorting method and system are extremely simple and low-cost, assuring a speedy, streamlined process of automatic sorting. 1/941 While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as exemplification of the preferred embodiments., Those skilled in the art will envision other possible variations that are within its scope. Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents. /941
