For illustration, and as will be explained in more detail below, the control circuit(s) 36 may be operative to
The bird vaccination system 30 may comprise a camera 50 for image data acquisition. The camera 50 may be operative to capture a 2D image, a 3D image (i.e., an image having depth information for each one of a plurality of pixels), and/or an infrared (IR) image.

The camera 50 may be provided separately from the support 31 or may be mounted on the support. Providing the camera 50 separately from the support 31 provides enhanced versatility. Mounting the camera 50 on the support 31 provides enhanced convenience for the user.
The camera 50 is positioned generally upstream, along the first direction 101, of the applicator carrier 41. I.e., the camera 50 and applicator carrier 41 are arranged such that the bird 100 passes the camera 50 before it passes the applicator carrier 41.

The camera 50 and/or control circuit(s) 36 may be operative to post-process captured image data. For illustration, 3D surface contour data may be derived from the image data captured by the image sensor 51.
Alternatively, a stereo-camera may be used to captured 3D image data.
As illustrated in
At step 71, image data acquisition is performed. Image data acquisition may comprise capturing 3D and/or IR image information. Image data acquisition may comprise capturing 3D surface contour information of the bird, using a structured-light 3D camera.
At step 72, a target position is identified at which the fluid discharge opening is to impinge on the bird. Identifying the target position may comprise one or several of: determining, using the image data acquired at step 71, a position of the bird 100 relative to a retaining bracket on which the bird 100 is retained and/or physiological characteristics of the bird 100; and identifying the target position of the fluid discharge opening responsive to the position of the bird 100 relative to the retaining bracket 22 and/or the physiological characteristics of the bird 100.
At step 73, the actuator 33 may be controlled responsive to the target position identified at step 72.

The actuator 33 may be controlled in such a manner that,
Steps 71-73 may be repeated in an iterative manner to successively administer fluid (e.g., vaccination fluid) to birds. The repetition rate may be fairly high to, e.g., accommodate vaccination of at least 1000, at least 2000, at least 3000, at least 4000, at least 5000, or at least 6000 birds per hour.
The fluid delivery device 60 with the fluid discharge opening 61 may perform a reciprocating movement 106 along the first direction 101, to return the fluid delivery device 60 to an initial position once a vaccination has been completed.
The velocity profile in the first time interval 75 is dependent on the acquired image data. For illustration, the applicator carrier 41 with the fluid discharge opening 61 may need to be displaced faster or slower than the travel speed vt at which the bird is being moved, in order to ensure that the fluid discharge opening 61 is positioned in a manner that depends on the position and/or size of the bird, as reflected by the image data.
The velocity in the second time interval 76 may be substantially constant and equal to the travel speed vt at which the bird is being moved by the conveying mechanism 20.
The velocity in the third time interval 77 may be independent of the image data and may cause the applicator carrier 41 to be returned to an initial position before a next operating cycle starts.
The abutment member 42 and the fluid delivery device with the fluid discharge opening 61 may be actively pushed against the bird 100 when the applicator carrier 41 is positioned as desired for administering the fluid. The abutment member 42 may have a contoured surface 44 that is shaped to abuttingly receive a portion of the bird's body, such as breast, wing, or head of the bird 100.
The abutment member 42 may be reversibly releasable attached to the applicator carrier 41. The bird vaccination system 30 may comprise one or several additional abutment members that are all reversibly releasably attachable to the applicator carrier 41. The different abutment members may correspond to different sizes, shapes, and/or body portions of the birds, depending on the birds that are being vaccinated (e.g., following grading of the birds) and/or depending on the part of the body to which fluid is to be administered (e.g., breast, wing, eye).
The abutment member 42 may be arranged so as to be displaceable relative to the applicator carrier 41. The abutment member 42 may be displaceable relative to the applicator carrier 41 along at least a third direction 103 which is orthogonal to the first direction 101 (along which the bird 100 is being moved past the bird vaccination system 30) and the second direction 102 (which is the vertical direction). The abutment member 42 and/or the applicator carrier 41 may comprise a linear guide mechanism 45 that may include tubular sections and rods matingly received in the tubular sections.
The bird vaccination system 30 may comprise one or several bias member(s) 46 that bias the abutment member 42 to a rest position. For fluid administration, the abutment member 42 must be displaced against the bias of the bias member(s) 46.
A fluid delivery assembly 62 is mounted on the applicator carrier 41. The fluid delivery assembly 62 may include one or several syringe barrel(s) and/or one or several needle(s) for administering fluid. The fluid delivery assembly 62 may be mounted on the applicator carrier 41 via a suspension 64. The suspension 64 may allow the fluid discharge opening(s) 61 to pivot relative to the applicator carrier 41, to better conform to the bird's body. The suspension 64 may allow the fluid discharge opening(s) 61 to pivot about a first pivot axis 65 and, optionally, about a second pivot axis. The suspension 64 may be a cardanic suspension.
The fluid delivery assembly 62 may include two or more than two fluid discharge openings (e.g., more than two needle tips). Each of the different fluid discharge openings may be operative to dispense a different one of several fluids.
The fluid delivery assembly 62 may comprise connectors 66 for receiving and/or dispensing fluid, such as vaccination fluid. Reservoirs for the fluid may be provided locally in the fluid delivery assembly 62 and/or separately from the vaccination head 40. Different ones of the connectors 66 may be in fluid communication with different ones of the fluid discharge openings.
A housing 38 may be arranged on the support 31 for accommodating various electronic components, such as the control circuit(s) 36, the interface (37), and, optionally, at least an image sensor 51 and/or a structured light projector 52 of the camera 50.
A computer of the conveying mechanism 20 may be communicatively coupled to the bird vaccination system 10. Information on, e.g., the weight of one or several bird(s) may be communicated from the computer of the conveying mechanism 20 to the control circuit(s) 36 of the bird vaccination system for dosage adjustment or other purposes. Information on the vaccination may be communicated form the vaccination system 10 to the conveying mechanism 20 for use in, e.g., grading or determining the position at which a bird is to be released from the conveying mechanism 20.
Various effects and advantages are attained by the systems and methods according to embodiments. The systems and methods afford efficient positioning of the fluid discharge opening for administering fluid(s) to a bird. Fluid(s), such as vaccination fluids, can be administered to a bird in an efficient manner. Differences in bird position relative to its retaining bracket and/or differences in bird physiology may be taken into consideration when controlling an actuator for positioning the fluid discharge opening. The control of the actuator may be performed in a fully or at least partially automated manner, affording high throughput and fast process times.
While embodiments may use 3D surface contour information for performing control operations in a fluid administration system, the systems and methods may process IR images to determine how a fluid discharge opening is to be positioned.
While embodiments may use 3D surface contour information for performing control operations in a fluid administration system, the systems and methods may perform a feature extraction based on 2D or 3D images to determine how a fluid discharge opening is to be positioned.
While embodiments may be used in association with vaccination systems, the systems and methods may generally be used for administering various therapeutic or non-therapeutic fluids.
