Definitions

  • An apparatus for sorting eggs or similar objects according to their weight comprises a plurality of juxtaposed balances, of
  • the invention relates to an apparatus for sorting eggs or similar objects according to their weight, in which the serially supplied objects are stepwise passed over and weighed on a plurality of juxtaposed balances of which the sorting apparatus is composed.
  • a sorting apparatus is characterized in that at least the first balance in the supply direction of the objects to be sorted is double-acting and adapted. for discharging in the same station both objects having a weight exceeding an adjusted maximum and having a weight below an adjusted minimum.
  • a sorting apparatus based on the above principle may have several structural designs. To explain the invention, two exemplary embodiments will be described, both limited to the double-acting balance to which a plurality of conventional balance are connected in the supply direction of the objects to be sorted.
  • FIG. 1 shows diagrammatically a front elevational view of the first exemplary embodiment of the double-acting balance
  • FIG. 2 is a section according to the line lI-Il in FIG. 1;
  • FIG. 3 is a section according to the line III-III in FIG. 1;
  • FIG. 4 shows diagrammatically a front elevational view of the second embodiment of the double-acting balance
  • FIG. 5 is a section according to the line VV in FIG. 4;
  • FIG. 6 is a section according to the line VlVI in FIG. 4.
  • the double-acting balance comprises a U-shaped standard 2 with a shaft 3, on which two balance levers 4 and 5 are journaled, the standard being mounted on a vertically reciprocating support rail 1.
  • the force arm of the balance lever 4 is provided with an adjustable weight 6, while on the load arm there is mounted a load scale 7 together with a finger 8, which extends across and some distance above the extremity of the load arm of the balance lever 5, the force arm of which is provided with an adjustable weight 9.
  • the balance lever 4 comprises an upwardly extending pin 10 and the balance lever 5 comprises an upwardly extending pin 11.
  • an ejector 'device comprising a carrier 12 for an arm 14 mounted thereon for rocking movement by means of a shaft 13.
  • This arm 14 has on the inner side a stop 15 with a recess 16 on the lower side, in which under certain conditions the upper end of the pin 10 of the balance lever 4 can engage, and a guide cam 17 with a recess 18, in which under certain conditions the upper end of the pin 11 of the balance lever 5 can engage.
  • each object 19 of a series of objects supplied by a conveyor chain 21 which is stepwise advanced over guide rails 20 is first subjected to a weighing by the double-acting balance heretofore described.
  • the carrier 1 When the carrier 1 is moved upwardly, the object 19 is lifted from the conveyor chain 21 'by the load scale 7. If the weight of the object is less than that to which the balance lever 4 has been adjusted by means of the adjusting weight 6, the balance lever 4 will not tip and the pins 10 and II will maintain their initial position.
  • the pin upon further upward movement of the carrier 1, the pin it will remain clear of the guide cam 17, but the upper end of the pin 10 will penetrate into the recess of the stop 15 and subsequently swing with arm 14 to the left,
  • the double-acting balance comprises two balance levers 23 and 24 joumaled on a stationary carrier 22, which carriers are respectively provided with an adjustable weight 25 and 26.
  • the balance lever 23 is provided with a load scale 27, a pin 28 constructed as a stop and a finger 29 extending across and some distance above the extremity of the balance lever 24.
  • an ejector device comprising an ejector 31 slidable in sleeve bearings 30, with ejector, through the medium of a compression spring 32, is axially reciprocated by a drive means 33 reciprocable'at periodic intervals.
  • a drive means 33 reciprocable'at periodic intervals.
  • an arm 34 On the ejector 31 there is mounted an arm 34 with a pin 35.
  • the objects are first one by one put on the load scale 27 of the above double balance by a carrier, not shown, which stepwise lifts the series of objects to be sorted, moves them in the supply direction of the series and drops them on the scales of the balances appurtenant to the sorting apparatus. If the weight of an object 36 dropped on the load scale 27 is less than the weight to which the balance lever 23 has been adjusted by means of the adjusting weight 25, the balance lever 23 maintains its initial position. As a result, upon the next operating stroke of the drive means 33, the ejector 31, whose pin 35 can freely passover the stop 28 of the balance lever 23, will push the object 36 from the load scale 27.
  • both the balance lever 23 and, through the medium of the finger 29, the balance lever 24 will tip. Consequently, the stop 28 of the balance lever 23 will swing upwardly, so that upon the operat ing stroke of the drive means 33 the ejector 31, whose pin 35 then passes under the stop 28, will push the object 36 from the load scale 27. If the weight of an object 36 placed on the load scale 27 ranges between the minimum and the maximum weight to which the double-acting balance has been adjusted, only the balance arm 23 will tip, but it will come to rest with the finger 29 on balance lever 24, which maintains its initial position.
  • the stop 28 will swing to such a position that its extremity comes to lie in the path of movement of the pin 35.
  • the movement of the ejector 31 will be arrested in that the pin 35 strikes the stop 28, and only the compression spring will be compressed.
  • the object 36 will remain on the load scale 27 to be brought to a next balance of the sorting apparatus.
  • a double acting balance for sorting eggs and similar objects by their weight for selecting objects within a predetermined weight range comprising:
  • balance levers mounted in side-by-sidc relation for rotation about substantially parallel axes and having weightedl'orce arms, a first of said levers having a load scale formed for receipt of an object to be sorted;
  • each balance lever is provided with a pin (10, II), which is adapted to coact with a stop l6. 18) of its own mounted on the ejector device for operating said ejector device.
