Abstract: A new chick production method and a new chick production system are obtained which are different from a conventional method in which all live eggs are collectively accommodated in a hatcher tray to develop chicks. The chick production method of the present invention divides mid-hatch eggs into a plurality of groups based on physical information measured for the mid-hatch eggs during a period from when the eggs are accommodated in a setter tray to when the eggs are transferred to a hatcher tray, and accommodates the mid-hatch eggs in the hatcher tray to develop chicks. In addition, a chick production system of the present invention includes a measurement unit, a sorting unit, and an accommodation unit, and the chicks are developed by each of a plurality of hatcher trays.

Abstract: A hatching egg inspection apparatus includes: a plurality of light emitter, the light emitter being disposed two dimensionally at prescribed positions; light receiver, which are provided in a one-to-one relationship with the light emitter and each of which receives light from the corresponding light emitter; and an egg container, which is for arraying in advance a hatching egg between each of the light emitter and the light receiver corresponding thereto. Each hatching egg is inspected by the corresponding light receiver that receives, among the lights from all the light emitter, transmitted light that transmitted through the interior of the hatching egg. When one light emitter of the plurality of light emitter is emitting light, other of the light emitter within a prescribed range centered on the one light emitter do not emit light.

Abstract: A device for monitoring the normal operation of weighing instruments (X1, X2, and X3) for chicken eggs used in a weight grading apparatus A for chicken eggs has a judging device 12 for monitoring the normal and abnormal operation of the weighing instruments (X1, X2, and X3) depending on whether or not the weight detected by the weighing instruments (X1, X2, and X3) indicates a predetermined state, as well as a display 13 for outputting a result of judgement by the judging device 12.

Abstract: An apparatus for sorting and packaging articles includes: a pair of distributing conveyors which are respectively translated and convey articles; a pair of primary accommodating mechanisms each adapted to accommodate in a row articles distributed and released from each of the distributing conveyors; a pair of standby accommodating mechanisms each adapted to accommodate by types of groups of transferred articles in one or more groups those groups of articles which are each transferred collectively from each of the primary accommodating mechanisms; a pair of transferring mechanisms each adapted to receive the group of articles from each of the standby accommodating mechanisms; and a common filling mechanism for filling the groups of articles received from each of the transferring mechanisms into a predetermined container.

Abstract: A warm water supply spot is located near a top end of an egg conveyance device and the degree of slope for the device is increased in the region from the water supply spot to the top end, so that the water dammed by the egg moving up the egg conveyance device does not overflow at the top end. The water is used efficiently without waste.

Abstract: An article collecting device comprising: feed unit 5 for feeding a set of articles smaller in quantity than a target quantity for collection; a recirculating conveyer 2 for conveying a set of articles fed by the feed unit 5; an operation unit 14 for combining at least two sets of articles fed during conveyance of the set of articles by the conveyer and determining whether a target quantity of articles as a preset collection unit is obtained; and an opening unit 12 for discharging the sets of articles combined as the target quantity from the conveyer to a bagging and packaging unit 13 as the result of the combination by the operation unit.
