Definitions

  • the present invention relates to a method and apparatus for examining eggs.
  • the present invention relates in particular to a method and apparatus for determining eggshell characteristics of eggs.
  • the method according to the present invention comprises:
  • the deformation contact time is inversely proportional to the shell stiffness (and the eggshell strength). The shorter the deformation contact time, the better (higher) the shell stiffness and the higher the eggshell strength. By determining the deformation contact time, thus, relatively simply, an estimate can be provided of the eggshell stiffness (and shell strength).
  • the deformation contact time mentioned is also called the impact duration, i.e. the time duration during which the two impacting elements (i.e. the egg and the deformer) are in direct mechanical contact (touch each other).
  • a quality parameter such as the strength and/or stiffness can be determined.
  • Such a method of detection can be suitably applied to sorting machines for eggs.
  • the method comprises, for instance, determining, during deforming (of a part of the egg), the deformation contact time.
  • the method according to the invention has one or more of the characteristics:
  • a deformer initial contact velocity is preferably used together with the deformation contact time mentioned for determining the eggshell stiffness (and/or eggshell strength), which appears to lead to particularly good results.
  • the present invention further provides an apparatus for examining eggs, in particular for determining eggshell characteristics of eggs, the apparatus comprising:
  • the apparatus has one or more of the following characteristics:
  • the apparatus can be configured, for instance, to use a deformer initial contact velocity (together with the deformation contact time) in determining the shell stiffness and/or the eggshell strength.
  • this method or this apparatus can be directly used and applied in sorting eggs.
  • a roller conveyor is a main element of sorting machines known to any skilled person, mostly as part of a sorting system.
  • FIG. 1 schematically shows an example of an apparatus according to the invention
  • FIG. 2 shows an example of a detection signal for determining the shell stiffness (and/or shell strength) of an egg.
  • FIG. 1 gives a schematic view of a roller conveyor 1 as is generally known and used in sorting machines for eggs.
  • An egg E rests on rollers 2 , the rollers 2 forming at least one row, these rollers 2 being usually provided on axles (in this schematic drawing perpendicular to the plane of the drawing), and these rollers being usually mutually connected at the ends of the axles by endless chains that are guided over end wheels and are driven at one of the ends.
  • axles in this schematic drawing perpendicular to the plane of the drawing
  • an excitation member or deformer 3 and an optical detector 4 are indicated.
  • Such an excitation member or deformer is known in this field of technology and described in, for instance, EP738888 mentioned hereinabove, and in EP1198708 and in EP1238582.
  • contact times upon tapping or impacting can be determined.
  • a hammer as mentioned in EP1238582 can be provided with an accelerometer, for instance a piezo element, for measuring such a contact time.
  • Such accelerometers can be of the type that energizes the inflation of air bags in automobiles upon collision.
  • the use of the detector according to EP738888 will be described in further detail on the basis of FIG. 2 .
  • the optical detector 4 can be a camera for taking rapid shots, or also a laser vibrometer or measuring optics generally known. Such optical equipment allows determination of times, distances and velocities over very short time durations and is therefore highly suitable for carrying out such detection in the above mentioned sorting machines.
  • a signal is represented that is produced by the detector as is extensively described in EP738888.
  • This signal shape shows how a ball bounces on an egg several times. More particularly, there is shown the interval of time of the sound intensity I that is measured by a microphone in the column of which the bouncing ball forms the end. Four collisions between the ball and the egg can be seen and hence also four bouncing movements.
  • the shape of the signal for one single bouncing movement is the result of the standing wave in the air column between the ball and the microphone, and is damped.
  • a time duration ti is indicated. This time duration is measured between two successive zero axis crossings of the first maximum intensity to be recognized for each bounce, and is substantially equal to the earlier mentioned contact time between the ball and an egg. Deviations thereof should be attributed to the construction of the detector, i.e. the distances to the microphone and the characteristics of the microphone. If required, this can be corrected for.
  • time duration of such a single reciprocating movement also to be called bounce time ⁇ t.
  • This time duration makes it possible, with the control that is applied to the ball, i.e. in the field of gravity in combination with an electromagnetic field, to determine the velocity (V n0 ) of the ball at the time of impact, the initial contact velocity.
  • V n0 the velocity of the ball at the time of impact
  • ⁇ t is the bouncing time (s) and K1 and K2 are empirically determinable constants.
  • the initial contact velocity can also be determined in another manner (for instance by processing optical measuring data), which will be clear to the skilled person.
  • the apparatus can be configured, for instance, for carrying out/controlling the bouncing such that a predetermined initial contact velocity (v c ) is achieved.
  • the above-mentioned determinations make it possible to determine a shell stiffness parameter which parameter is derived with the Hertz model for such an egg-ball system. It is known to any skilled person how such a parameter relates to the above-mentioned shell stiffness or eggshell strength as determined according to the above-mentioned compression methodology, or also a specific stiffness determined in another way.
  • K H ( c ⁇ ) 5 / 2 ⁇ v n ⁇ ⁇ 0 - 1 / 2 ⁇ m ( 2 )
  • K H is the Hertz stiffness (N/m 3/2 )
  • v n0 is the initial contact velocity (m/s)
  • ⁇ is the deformation contact time (s)
  • m is the effective mass of the system, (kg), i.e.:
  • m 1 is the mass of the deformer (in this case the bouncing ball) and m 2 is the mass of the respective egg.
  • apparatuses can be used where tapping is carried out not with a ball but with a pin or a needle.
  • tapping is carried out not with a ball but with a pin or a needle.
