Definitions

  • the present invention relates to a sex determination device.
  • the traditional method for sexing chicks is the feather identification method, which involves determining the sex of chicks based on the state of their feathers shortly after hatching.
  • a sexing device that uses this feather identification method involves moving chicks on an inclined conveyor, capturing images of the chicks with their wings spread, and then determining the sex of the chicks from the captured images.
  • the present invention was made to solve the above problems, and aims to enable chicks to spread their wings using a simple structure and accurately distinguish between male and female chicks.
  • the sex discriminating device is a sex discriminating device for discriminating the sex of chicks, and is characterized by comprising a dropping mechanism for dropping the chicks, an imaging unit for imaging the chicks dropped by the dropping mechanism, and a discrimination unit for discriminating the sex of the chicks based on the image captured by the imaging unit.
  • This sex determination device takes advantage of the tendency of chicks to spread their wings as they fall, so that the chicks will undoubtedly spread their wings when they fall.
  • By capturing an image of the chick as it falls using the falling mechanism it is possible to reliably capture an image of the chick's feathers.
  • the image captured by the imaging unit makes it possible to determine the state of feathering of the chick and to determine whether it is male or female.
  • the dropping mechanism it is desirable to have a transport section for transporting the chicks, and to drop the chicks from a terminal end of the transport section in the transport direction. With this configuration, the transportation, dropping and sexing of chicks can be carried out continuously.
  • the sex determining device of the present invention desirably has a discharge section which forms a landing surface for the chicks dropped by the dropping mechanism and which discharges the dropped chicks.
  • the dropped chicks can be removed as they are. Also, the chicks can be separated into males and females at the removal section.
  • the present invention allows the chicks' wings to be spread with a simple structure, and the sex of the chicks can be accurately determined.
  • FIG. 13 is a plan view showing a schematic configuration of a sex determining device according to a modified embodiment.
  • FIG. 13 is a plan view showing a schematic configuration of a sex determining device according to a modified embodiment.
  • FIG. 13 is a front view showing a schematic configuration of a sex determining device according to a modified embodiment.
  • the sex discriminating device 100 of this embodiment utilizes the habit of chicks C spreading their feathers C1 when they fall.
  • the chicks C to be discriminated are those on the first or second day after hatching, and there is a large difference in the growth rate of feathers between males and females of these chicks C.
  • the sex discriminating device 100 includes a drop mechanism 2 that drops the chicks C, an image capturing unit 3 that captures an image of the chicks C dropped by the drop mechanism 2, and a discrimination unit 4 that discriminates the sex of the chicks C based on the image captured by the image capturing unit 3.
  • the dropping mechanism 2 drops the chicks C during transport.
  • the dropping mechanism 2 has a transport section 21 that transports the chicks C, and a discharge section 22 that transports the chicks C. Both the transport section 21 and the discharge section 22 can be constructed using belt conveyors.
  • the transport section 21 is also provided with a mechanism for transporting the chicks C one by one.
  • the conveying direction terminal end 21x of the conveying section 21 is located at a higher position than the discharge section 22. With this configuration, the chicks C fall from the conveying direction terminal end 21x of the conveying section 21.
  • the discharge section 22 forms a landing surface 22x for the chicks C that have fallen from the conveying direction terminal end 21x, and discharges the fallen chicks C.
  • the landing surface 22x is formed by the upper surface of the belt conveyor that constitutes the discharge section 22.
  • the end 21x of the conveying section 21 in the conveying direction is located at a height of 100 mm to 200 mm above the landing surface 22x of the discharge section 22.
  • the falling distance of the chick C is 100 mm to 200 mm.
  • the imaging unit 3 captures images of the chicks C that are dropped and landed by the drop mechanism 2. This imaging unit 3 captures images of the chicks C that fall from the transport direction terminal end 21x from vertically above. Specifically, the imaging unit 3 is provided above the transport direction terminal end 21x of the transport section 21, facing the landing surface 22x of the discharge section 22.
  • the imaging format of the imaging unit 3 may be either a moving image or a still image. If it is a moving image, it is possible to continuously image the chick C from the end 21x of the transport direction until after it lands on the landing surface 22x, and it is possible to reliably image the feathers of the wing C1 of the chick C. Even if it is a still image, it is possible to reliably image the feathers of the wing C1 of the chick C by capturing multiple images from the end 21x of the transport direction until after the chick C lands on the landing surface 22x.
  • the discrimination unit 4 discriminates the sex of the dropped chicks C based on the captured image obtained by the imaging unit 3.
  • the discrimination unit 4 can be configured as a computer having a CPU, memory, an input/output interface, an AD converter, a display device, an input device, etc.
  • the discrimination unit 4 discriminates the sex of the dropped chick C based on previously created reference data (reference data for discriminating between male and female chicks) and the captured image captured by the imaging unit 3.
  • a machine learning model can be used for the discrimination unit 4.
  • This machine learning model is a model trained by machine learning using training data consisting of captured images of the feathers C1 of a male chick C and captured images of the feathers C1 of a female chick C.
  • This machine learning model is generated in advance and stored in memory.
  • the discrimination unit 4 can then input the captured images captured by the imaging unit 3 into this machine learning model, thereby discriminating between the male and female of the fallen chick C.
  • the sexing device 100 of this embodiment utilizes the tendency of chicks C to spread their wings C1 when they fall, so that the chicks C will reliably spread their wings C1 when they fall. Then, by capturing an image of the chick C that has fallen using the falling mechanism 2, it is possible to reliably capture an image of the feathers C1 of the chick C. As a result, the state of feather growth of the chick C can be determined from the image captured by the imaging unit 3, and the sex of the chick can be determined.
  • the falling chick C is imaged from vertically above, so the feathers C1 of the chick C can be reliably imaged regardless of the direction the chick C is facing.
  • the transport section 21 and the discharge section 22 can be arranged to intersect.
  • multiple transport sections 21 can be provided for one discharge section 22, improving the efficiency of identifying chicks C.
  • the discharge section 22 may have a removal section 23 that separates and removes one of the chicks that has been sexed from the discharge section 22.
  • This removal section 23 may be configured to remove the male chick from the discharge section 22 if the dropped chick is determined to be a male.
  • the removal section 23 may be configured to push the male chick on the discharge section 22 out of the discharge section 22 by, for example, an air cylinder.
  • the male chick pushed out of the discharge section 22 is stored in the male chick storage section 24.
  • the female chicks are discharged by the discharge section 22 to the female chick storage section 25.
  • the transport direction terminal end 21x of the transport unit 21 may be inclined, for example, in the width direction.
  • the chick C will lose its posture as it falls at the transport direction terminal end 21x.
  • the chick C will then lose its posture as it lands, which can extend the time it spends spreading its wings C1. This makes it easier for the imaging unit 3 to capture an image of the chick C with its wings spread.
  • the landing surface 22x of the discharge section 22 may also be inclined. By inclining the landing surface 22x, the chick C loses its posture when it lands, and the time for which it spreads its wings C1 can be extended. This makes it easier for the imaging unit 3 to capture an image of the chick C with its wings C1 spread.
  • the configuration of the dropping mechanism 2 is not limited to the above embodiment, and is not limited to a configuration in which the chicks are dropped from the end 21x of the conveying section 21 in the conveying direction, but may be a configuration in which the chicks are dropped midway through the conveying section 21.
  • the chicks C may be dropped by opening up part of the conveying surface of the conveying section 21.
  • the dropping mechanism 2 may also be configured using a lifting table. In this case, the chicks are placed on the lifting table, and the lifting table is lowered in this state, causing the chicks to drop on the spot and land on the lowered lifting table.
  • the landing surface 22x is formed by the discharge section 22, as shown in FIG. 4, the landing surface 22x may be formed by the stage 26.
  • the stage 26 may be provided with a sorting mechanism 27 for separating males and females.
  • This sorting mechanism 27 sorts the chicks C based on the discrimination results by the discrimination section 4. For example, the sorting mechanism 27 sorts the chicks C that are discriminated as male to the male chick storage section 28 (or discharge section) and sorts the chicks C that are discriminated as female to the discharge section 22 (or female chick storage section).
  • the imaging unit 3 captures images of the chicks C falling from the end 21x of the conveying direction from vertically above, but instead of capturing images from vertically above, it may capture images of the falling chicks C from diagonally above, or from the side.
