DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a packaging apparatus for packaging hen's eggs, fruits, etc., into the packs containing a predetermined number of pieces of said commodities.
BACKGROUND ART
According to the weight standards for hen's eggs for instance, they are classified by weight into the following divisions: SS (40 g to not greater than 46 g), S (46 g to not greater than 52 g), MS (52 g to not greater than 58 g), M (58 g to not greater than 64 g), L (64 g to not greater than 70 g), 2L (70 g to not greater than 76 g) and substandard division. According t the conventional packaging machines, only the eggs having the weights within one weight division have been packed in one packaging container. Generally, there is a tendency that the consumers buy the packs of eggs of certain weight divisions. Consequently, there arises a situation where the packs containing the eggs of certain weight divisions, for example, L and M divisions, have a good sale while the packs of eggs of other divisions do not have a good sale, with the result that the commercial value of the eggs of other weight divisions than L and M drops.
In order to eliminate such impropriety, it is suggested to contain the eggs of various weight divisions in one pack in such a way that the individual packs will become substantially equal to each other in weight and to put such packs on sale. However, no packaging apparatus capable of making such packs has yet been proposed.
DISCLOSURE OF THE INVENTION
According to the present invention, there is provided a packaging apparatus by which the commodities of the same kind but differing in physical characteristics can be contained mixedly in one pack and the produced individual packs have substantially no difference from each other in weight.
More specifically, in accordance with this invention, there is provided said type of packaging apparatus comprising means for successively conveying the commodities to be packed, means for successively detecting the physical characteristics of said commodities conveyed by said conveyance means, means for sorting out said conveyed commodities according to the physical characteristics detected by said detecting means, plural means for accumulating the respective commodities sorted out by said sorting means, means for taking out a predetermined number of pieces of commodities accumulated in each of said accumulating means and forming a set of a predetermined number of pieces of commodities to be packed, and means for putting into a packaging container each of the sets of commodities to be packed formed by said forming means.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a preferred embodiment of the present invention;
FIG. 2 shows the details of a container for conveying an egg in the apparatus shown in FIG. 1; and
FIG. 3 shows an electric control circuitry adapted in the apparatus shown in FIG. 1.
BEST MODE FOR CARRYING OUT THE INVENTION
In FIGS. 1 to 3, the containers 2 each holding hen's egg 1 as commodity to be packed are carried in the direction A on belt conveyors 3, 4, 5 operated by an electric motor 6. Conveyor 4 is provided with a detector 7 for detecting the weight of each egg 1 being carried, and the detected weight of each egg 1 is supplied to a control unit 8 comprising micro-computers. Always one egg 1 held in container 2 is transferred from conveyor 3 onto said conveyor 4. After the weight of the egg 1 has been detected by said detector 7, said egg 1 is then transferred onto the next conveyor 5. A series of belt conveyors 9-14 are provided along and transversely to said conveyor 5, said conveyors 9-14 being operated by an electric motor not shown. At one end of each of said conveyors 9-14 is provided sorting-out gates (15-20) each of which is operated to make a turn (open) by a corresponding electric motor (21-26). When any one of said gates 15-20 is operated to open, the container 2 holding an egg 1 transferred by said conveyor 5 is transferred onto a transverse conveyor corresponding to said particular gate. The operation of said g
