Description

Technical Field

[0001] This invention relates to the field of poultry wing detection, and in particular to a device and method for detecting residual wings. Background Technology

[0002] After poultry undergoes processes such as feather removal to become carcasses, their legs are hooked and they are suspended upside down along a conveyor line into various cutting units for cutting according to the parts of the poultry.

[0003] Inevitably, poultry wing bones will break during various processing steps. Broken wing fragments have different values ​​than normal, unbroken wing parts, so it is necessary to distinguish between broken and normal wing parts to facilitate subsequent separate sales according to value.

[0004] Existing technology uses X-rays to photograph the wings to detect whether the internal bones are broken. However, the high price of X-ray detection equipment results in an excessively high total cost for wing defect detection devices. Summary of the Invention

[0005] The present invention aims to solve the above problems by providing a wing-defect detection device and method, which solves the problem of excessive cost of wing-defect detection devices.

[0006] A residual wing detection device includes: a first limiting element, a moving element, a resistance element, a detection element, and a frame. The first limiting element is fixed in position relative to the frame and is used to limit the displacement of the bird's wing. The moving element is in contact with the bird's wing. The resistance element is used to provide resistance to the moving element, which hinders the movement of the bird's wing along the direction of the first limiting element. The detection element is used to detect the movement of the moving element.

[0007] Furthermore, a channel is formed between the two first limiting elements on the left and right sides, allowing birds to move from front to back, and the moving elements on the left and right sides of the channel extend into the channel respectively.

[0008] Furthermore, it also includes a second limiting element, which is connected to the frame and is used to limit the movement trajectory of the moving element.

[0009] Furthermore, the first limiting element includes an upper guide rod in the middle of the wing and a lower guide rod in the middle of the wing. The upper guide rod in the middle of the wing is located above the lower guide rod in the middle of the wing, and the upper guide rod in the middle of the wing and the lower guide rod in the middle of the wing are in contact with the upper and lower sides of the wing, respectively.

[0010] The first limiting element also includes a neck guide rod, with two neck guide rods located between two lower wing guide rods, the neck guide rods being used to limit the neck of the poultry;

[0011] The first limiting element also includes a wingtip guide plate, which is located outside the upper guide rod and the lower guide rod in the middle of the wing, and is used to limit the wingtip.

[0012] Furthermore, the motion element also includes a rotating rod, the second limiting element is a vertical shaft, the rotating rod rotates about the second limiting element as an axis, one end of the rotating rod extends into the channel, and the other end is fixedly connected to a detection plate, the detection element is used to detect the position of the detection plate, the detection element is fixedly connected to the frame, and the second limiting element is fixedly or rotatably connected to the frame;

[0013] The rotating rod also includes a limiting rod, which is fixedly connected to the front side of the rotating rod. An angle is formed between the limiting rod and the rotating rod. The limiting rod is used to limit the position of the wingtip.

[0014] It also includes a limiting post, which is fixedly or rotatably connected to the frame, and the limiting post is used to limit the initial position of the rotating rod under the drive of the resistance element.

[0015] Furthermore, the resistance element includes a weight, a steel wire, and a roller. The roller is rotatably connected to the frame. The two ends of the steel wire are respectively connected to a rotating rod and a weight. The steel wire is in contact with the roller. The roller is used to support and guide the steel wire. The roller is rotatably connected to the frame.

[0016] The resistance element also includes a turntable, which is coaxial with the second limiting element. The moving element is fixedly connected to the turntable, and the turntable rotates about the second limiting element as an axis. The end of the steel wire is connected to the turntable.

[0017] The resistance element further includes a cage connected to the weight, the cage restricting the horizontal movement of the weight;

[0018] The resistance element also includes a mounting rod, with the upper end of the steel wire connected to the end of the steel wire, and the weight being detachably connected to the mounting rod.

[0019] Furthermore, the detection element is a photoelectric sensor or a limit switch; the detection element is connected to the control device.

[0020] Furthermore, it also includes a drive device and a push plate. The drive device is located below the channel, and the push plate is connected to the drive device. The drive device drives the push plate to move linearly from front to back in the channel. The push plate contacts the shoulder of the poultry to limit the position of the poultry's shoulder.

[0021] Furthermore, the position of the first limiting element relative to the frame is adjustable.

[0022] A detection and processing method using the aforementioned residual wing detection device includes the following steps:

[0023] Step S1: The poultry enters between the two first limiting elements from the front end. The first limiting elements limit the poultry, causing the poultry to move from front to back along the first limiting elements.

[0024] Step S2: The bird's wing comes into contact with the motion element located in the initial position. When the bones of the wing root and the middle of the wing are not broken, the motion element driven by the middle of the wing overcomes the resistance of the resistance element and moves the motion element to the detection position. When the bones of the wing root and the middle of the wing are broken, the motion element driven by the middle of the wing cannot completely overcome the resistance of the resistance element and the motion element cannot move to the detection position.

[0025] Step S3: The detection element detects whether the moving element has moved to the detection position. When the moving element is detected, it transmits a first signal to the control device; when the moving element is not detected, it transmits a second signal to the control device, and then the control device transmits a signal to the disengagement device or the marking device.

[0026] Step S4: The bird disengages from the moving element, and the moving element returns to or maintains its initial position;

[0027] Step S5: The detachment device or marking device processes the poultry corresponding to the second signal.

[0028] The present invention has the following advantages: the resistance element provides resistance to the moving element, the detection element checks the position of the moving element, and by detecting whether the strength of the wing is sufficient to drive the moving element to the designated position, it can be determined whether the bone in the wing is broken. The detection success rate is high and the cost is low, which solves the problem of excessive cost of residual wing detection devices; the first limiting element limits the wing and other parts of the bird, so that the wing can accurately reach the moving element, while reducing shaking and improving the accuracy of the position of the moving element during movement, thereby improving the accuracy of the detection element in detecting residual wing.

Therefore, they should not be construed as limitations on this invention.

[0040] Example 1:

[0041] like Figures 1 to 5As shown, a residual wing detection device includes: a first limiting element 1, a moving element 2, a resistance element 3, a detection element 4, and a frame 7. The first limiting element 1 is fixed relative to the frame 7 and is used to restrict the displacement of the wing of a bird 9. The moving element 2 contacts the wing of the bird 9. The resistance element 3 provides resistance to the moving element 2, preventing the wing of the bird 9 from moving along the direction of the first limiting element 1. The detection element 4 detects the movement of the moving element 2. The first limiting element 1 ensures that the wing of the bird accurately reaches the area in contact with the moving element 2, preventing the wing from wobbling or deflecting around the joint axis after encountering resistance, thereby improving the accuracy of the detection.

[0042] Furthermore, a through channel 10 is formed between the two left and right first limiting elements 1, allowing the poultry 9 to move from front to back. Motion elements 2 on the left and right sides of the channel 10 extend into the channel 10. It should be noted that the legs of the poultry 9 are connected to hooks. In the prior art, a conveyor line drives the hooks to suspend the poultry 9. This conveyor line is located above the channel 10, and it suspends the poultry 9 from front to back through the channel 10.

[0043] Furthermore, it also includes a second limiting element 8, which is connected to the frame 7. The second limiting element 8 is used to limit the movement trajectory of the moving element 2. The second limiting element 8 ensures that the moving element 2 can only move back and forth in the forward and reverse directions under a fixed movement trajectory, so as to avoid the moving element 2 from moving in other directions and affecting the detection element 4's detection of its position.

[0044] Furthermore, the first limiting element 1 includes an upper wing guide rod 11 and a lower wing guide rod 12. The upper wing guide rod 11 is located above the lower wing guide rod 12. The upper wing guide rod 11 and the lower wing guide rod 12 are in contact with the upper and lower sides of the joint between the wing midsection 92 and the wing root 91, respectively. The upper wing guide rod 11 and the lower wing guide rod 12 play a guiding and limiting role when the wing moves, reducing the left and right swaying of the wing midsection 92 and the rotation of the joint with the wing root 91.

[0045] Preferably, the first limiting element 1 further includes a neck guide rod 13, with two neck guide rods 13 located between two lower wing guide rods 12. The neck guide rods 13 are used to limit the neck of the poultry 9. The neck of the poultry 9 extends between the two neck guide rods 13. By limiting the position of the neck, the swaying amplitude of the neck is controlled, thereby reducing the overall swaying amplitude of the poultry 9 during movement.

[0046] Preferably, the first limiting element 1 further includes a wingtip guide plate 14, which is located outside the upper guide rod 11 and the lower guide rod 12 in the middle of the wing. The wingtip guide plate 14 is used to limit the wingtip 93 so that the wingtip 93 can smoothly enter the angle formed between the limiting rod 22 and the rotating rod 21 after it is released from contact with the wingtip guide plate 14.

[0047] Furthermore, the motion element 2 also includes a rotating rod 21, the second limiting element 8 is a vertical shaft, the rotating rod 21 rotates about the second limiting element 8 as an axis, one end of the rotating rod 21 extends into the channel 10, and the other end is fixedly connected to a detection plate 23. The detection plate 23 is used to increase the area, so that the detection element 4 can more easily detect the position of the detection plate 23 when using a photoelectric sensor. The detection element 4 is fixedly connected to the frame 7, and the second limiting element 8 is fixedly or rotatably connected to the frame 7.

[0048] Preferably, the rotating rod 21 further includes a limiting rod 22, which is fixedly connected to the front side of the rotating rod 21. An angle is formed between the limiting rod 22 and the rotating rod 21. The limiting rod 22 is used to limit the position of the wingtip 93 to prevent the wingtip 93 from shaking and affecting the detection results.

[0049] Preferably, it also includes a limiting post 24, which is fixedly or rotatably connected to the frame 7, and the limiting post 24 is used to limit the initial position of the rotating rod 21 under the drive of the resistance element 3.

[0050] Furthermore, the resistance element 3 includes a weight 31, a steel wire 32, and a roller 34. The roller 34 is rotatably connected to the frame 7. The two ends of the steel wire 32 are connected to the rotating rod 21 and the weight 31, respectively. The steel wire 32 is in contact with the roller 34. The roller 34 is used to support and guide the steel wire 32 and reduces frictional resistance. The roller 34 is rotatably connected to the frame 7. The resistance provided by the weight 31 to the moving element 2 is constant. Compared with the different forces generated by the spring due to different compression, the weight 31 provides a more stable force, which is conducive to making the moving element 2 move more accurately, thereby improving the detection accuracy.

[0051] Preferably, the resistance element 3 further includes a turntable 33, which is coaxial with the second limiting element 8. The motion element 2 is fixedly connected to the turntable 33, and the turntable 33 rotates about the second limiting element 8. The end of the steel wire 32 is connected to the turntable 33 (rotating, hooking, or fixing).

[0052] Preferably, the resistance element 3 further includes a retainer 35, which is connected to the weight 31. The retainer 35 restricts the horizontal movement of the weight 31 to avoid unstable resistance caused by the swaying of the weight 31.

[0053] Preferably, the resistance element 3 further includes a mounting rod 36, the upper end of the steel wire 32 is connected to the end of the steel wire 32, and the weight 31 is detachably connected to the mounting rod 36. By changing the number or mass of the weight 31, the magnitude of the resistance is changed to adapt to the wings of poultry 9 of different body shapes or breeds.

[0054] Furthermore, the detection element 4 is a photoelectric sensor or a limit switch; the detection element 4 is connected to a control device, which is a computer.

[0055] Preferably, the photoelectric sensor is a through-beam photoelectric sensor.

[0056] Furthermore, it also includes a drive device 6 and a pusher plate 61. The drive device 6 is located below the channel 10, and the pusher plate 61 is connected to the drive device 6. The drive device 6 drives the pusher plate 61 to move linearly from front to back in the channel 10. The pusher plate 61 contacts the shoulder of the poultry 9 to limit the position of the poultry 9's shoulder and reduce the swaying generated at the shoulder of the poultry 9. The drive device 6 can be a chain conveyor.

[0057] Furthermore, the position of the first limiting element 1 relative to the frame 7 is adjustable, thereby adapting to the wings and necks of poultry 9 of different body sizes or breeds. The wings of the poultry 9 include the wing root 91, the wing midsection 92, and the wing tip 93.

[0058] Furthermore, the frame 7 includes a mounting plate 5, which is used to mount the motion element 2, the resistance element 3, the detection element 4, and the second limiting element 8.

[0059] During operation, the hook moves along the conveyor line from front to back, allowing the poultry 9 to pass through the channel 10. Under the guidance structure at the front end of the first limiting element 1, the wings and neck of the poultry 9 enter the first limiting element 1. The wings of the poultry 9 are limited by the upper wing guide rod 11, the lower wing guide rod 12, and the wingtip guide plate 14; the neck of the poultry 9 is limited by two neck guide rods 13; and the shoulders of the poultry 9 are limited by the push plate 61. The push plate 61 moves synchronously with the hook in the channel 10.

[0060] The wing midpiece 92 of the bird 9 is in contact with the rotating rod 21.

[0061] If the bones of the wing midpiece 92 and wing root 91 are not broken, the entire wing has sufficient strength to overcome the resistance of the resistance element 3. The wing will drive the rotating rod 21 to rotate from the initial position to the detection position. The detection element 4 detects the detection plate 23 and transmits the first signal to the control device, which marks it as a normal wing. The wing drives the rotating rod 21 to rotate away from the channel 10. The wing disengages from the rotating rod 21 at the rotating rod 21. Under the drive of the weight 31, the rotating rod 21 returns to contact with the limiting post 24.

[0062] If the bones in the wing midpiece 92 and wing root 91 of the wing are broken, the overall strength of the wing is insufficient to drive the rotating rod 21 to move, or the rotating rod 21 rotates slightly but does not reach the detection position. The detection element 4 does not detect the detection plate 23 and transmits the second signal to the control device, which marks it as a damaged wing. The wing, compressed by the rotating rod 21, bends and deforms at the bone fracture point, thus allowing it to pass smoothly through the rotating rod 21.

[0063] Example 2:

[0064] like Figures 3 to 6 As shown, a residual wing detection device includes: a first limiting element 1, a moving element 2, a resistance element 3, a detection element 4, and a frame 7. The first limiting element 1 is fixed relative to the frame 7 and is used to restrict the displacement of the wing of a bird 9. The moving element 2 contacts the wing of the bird 9. The resistance element 3 provides resistance to the moving element 2, preventing the wing of the bird 9 from moving along the direction of the first limiting element 1. The detection element 4 detects the movement of the moving element 2. The first limiting element 1 ensures that the wing of the bird accurately reaches the area in contact with the moving element 2, preventing the wing from wobbling or deflecting around the joint axis after encountering resistance, thereby improving the accuracy of the detection.

[0065] Furthermore, a through channel 10 is formed between the two left and right first limiting elements 1, allowing the poultry 9 to move from front to back. The moving elements 2 on the left and right sides of the channel 10 extend into the channel 10 respectively. It should be noted that the legs of the poultry 9 are connected to a conveyor line of the prior art, which is located above the channel 10. The conveyor line hoists the poultry 9 from front to back through the channel 10.

[0066] Furthermore, it also includes a second limiting element 8, which is fixedly connected to the frame 7. The second limiting element 8 is used to limit the movement trajectory of the moving element 2. The second limiting element 8 ensures that the moving element 2 can only move back and forth in the forward and reverse directions under a fixed movement trajectory, so as to avoid the moving element 2 from moving in other directions and affecting the detection element 4's detection of its position.

[0067] It should be noted that the motion element 2, resistance element 3, and second limiting element 8 in this embodiment are different from those in Embodiment 1, but the rest of the principles are the same as those in Embodiment 1.

[0068] Furthermore, the second limiting element 8 is a cylindrical body, the moving element 2 is slidably connected to the second limiting element 8, the second limiting element 8 is fixedly connected to the frame 7, the two ends of the resistance element 3 are in contact with the moving element 2 and the second limiting element 8 respectively, and the resistance element 3 has elasticity.

[0069] Furthermore, the detection element 4 is located inside the second limiting element 8 and is fixedly connected to the second limiting element 8. Preferably, the detection element 4 is a photoelectric sensor or a limit switch.

[0070] Furthermore, the resistance element 3 is a spring.

[0071] Furthermore, the motion element 2 has a guide slope 201 formed on its front side.

[0072] During operation, the hook moves along the conveyor line from front to back, allowing the poultry 9 to pass through the channel 10. Under the guidance structure at the front end of the first limiting element 1, the wings and neck of the poultry 9 enter the first limiting element 1. The wings of the poultry 9 are limited by the upper wing guide rod 11, the lower wing guide rod 12, and the wingtip guide plate 14; the neck of the poultry 9 is limited by two neck guide rods 13; and the shoulders of the poultry 9 are limited by the push plate 61. The push plate 61 moves synchronously with the hook in the channel 10.

[0073] The wing 92 of the bird 9 contacts the guide slope 201 of the motion element 2. The force on the guide slope 201 is divided into two components: front-back and left-right. The left-right component will drive the motion element 2 to move.

[0074] If the bones of the wing midpiece 92 and wing root 91 are not broken, the entire wing has sufficient strength to overcome the resistance of the resistance element 3, pushing the drive motion element 2 from the initial position to the detection position. The detection element 4 detects that the motion element 2 has reached the detection position and transmits a first signal to the control device, which marks it as a normal wing. The wing drives the motion element 2 away from the channel 10, and the bird, after passing between the two motion elements 2, disengages from the motion elements 2. Under the elastic force of the resistance element 3, the motion element 2 returns to its initial position.

[0075] If the bones in the wing midpiece 92 and wing root 91 of the wing are fractured, the overall strength of the wing is insufficient to drive the motion element 2, or the motion element 2 slides slightly but does not reach the detection position. The detection element 4 does not detect the motion element 2 reaching the detection position and transmits a second signal to the control device, which marks it as a damaged wing. The wing, compressed by the motion element 2, bends and deforms at the fractured bone, thus allowing it to pass smoothly through the motion element 2.

[0076] Example 3:

[0077] A detection and processing method using the residual wing detection device as described in Embodiment 1 or 2 includes the following steps:

[0078] Step S1: The poultry 9 enters between the two first limiting elements 1 from the front end. The first limiting elements 1 limit the poultry 9, causing the poultry 9 to move from front to back along the first limiting elements 1.

[0079] Step S2: The wings of the bird 9 come into contact with the motion element 2 located in the initial position. When the bones of the wing root 91 and the middle of the wing 92 are not broken, the middle of the wing 92 drives the motion element 2 to overcome the resistance of the resistance element 3, so that the motion element 2 moves to the detection position. When the bones of the wing root 91 and the middle of the wing 92 are broken, the motion element 2 driven by the middle of the wing 92 cannot completely overcome the resistance of the resistance element 3, so that the motion element 2 cannot move to the detection position.

[0080] Step S3: The detection element 4 detects whether the moving element 2 has moved to the detection position. When the moving element 2 is detected, it transmits a first signal to the control device; when the moving element 2 is not detected, it transmits a second signal to the control device, and then the control device transmits a signal to the disengagement device or the marking device.

[0081] Step S4: The bird 9 disengages from the motion element 2, and the motion element 2 returns to or maintains its initial position;

[0082] Step S5: The detachment device or marking device processes the poultry 9 corresponding to the second signal.

[0083] When the detachment device is used, it drives the bird marked with vestigial wings 9 to detach from the hook when it is transported to the designated position on the conveyor line (after leaving the detection device).

[0084] When a marking device is used, it physically marks the birds 9 marked as having vestigial wings when they are transported to the designated location on the conveyor line (after leaving the detection device). Afterwards, the birds 9 marked as having vestigial wings are removed from the hook manually or mechanically.

[0085] This avoids mixing birds with normal wings and birds with damaged wings.

[0086] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
