Description

Technical Field

[0001] This invention relates to the field of foreign object detection technology, specifically to a fully automated sausage casing foreign object detection device. Background Technology

[0002] Sausage casings are the outer packaging of sausages, and their basic function is to ensure that the sausages do not spoil under certain conditions and within a certain time to meet the needs of storage and distribution. This function is provided by the barrier properties of the casings. In existing technologies, casing detection and sorting are mostly carried out after the casing shrinking process. However, foreign objects inside the shrinked casing cannot be identified, affecting the identification results. On the other hand, unshrinked casings are too long, making them inconvenient for detection and sorting. Using ordinary pneumatic pushers to push them out directly or clamps to pick them up results in low accuracy and is very easy to cause mechanical damage to the casings during movement, affecting the barrier properties of the casings. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a fully automated sausage casing foreign object detection device, which solves the problem of difficult detection and sorting of sausage casings before shrinking.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic sausage casing foreign object detection device, comprising a workbench, wherein the workbench is divided into a detection area, a non-conforming area, and a conforming area, and further comprising:

[0005] The identifier is fixed in the detection area by a support frame 2;

[0006] A conveying assembly is mounted on a workbench, and a mounting box that can move with it is installed on the conveying assembly.

[0007] The sausage casing is mounted on the mounting box and can be evenly wound around its surface by rotating the sausage casing.

[0008] The sausage wrapping assembly includes a rotating cylinder, which is a transparent hollow structure with a light source inside. Multiple support rods are evenly arranged around the outside of the rotating cylinder. The rotating mechanism drives the rotating cylinder to rotate, which can control the support rods to move closer to or away from the axis of the rotating cylinder, so that the sausage wrapping assembly can rotate with different diameters, which facilitates the separation of the sausage casing from the support rods for feeding.

[0009] The deflection mechanism can drive the sausage casing assembly to deflect vertically through the mounting box, which facilitates the feeding of sausage casings.

[0010] Furthermore, the identifier includes a first detection identifier and a second detection identifier, wherein the first detection identifier is used for the first detection of the casing;

[0011] The identifier is provided with a diameter-changing drive assembly below it. The diameter-changing drive assembly cooperates with the rotating mechanism to make the drum rotate in the forward or reverse direction. The reverse rotation of the drum can change the contact position between the casing and the support rod.

[0012] The second detection and identification device is used to perform a second detection of the casing after the contact position between the casing and the support rod is changed.

[0013] Furthermore, a connecting rod is hinged between the rotating cylinder and each support rod, and a second rotating shaft is fixedly provided at one end of the rotating cylinder near the mounting box, and the second rotating shaft is rotatably mounted on the mounting box;

[0014] The intestinal coil assembly also includes:

[0015] A disc, which is rotatably mounted on a second rotating shaft and rotatably connected to a mounting box, and has damping;

[0016] The first slide groove is evenly opened on the surface of the disk along the circumference, and the end of the support rod near the disk is provided with a first slider that cooperates with the first slide groove.

[0017] By driving the drum to rotate in the forward or reverse direction, the diameter of the spiral assembly is different in the forward and reverse rotation states.

[0018] Furthermore, the rotating mechanism includes a small bevel gear, which is coaxial with the rotating drum, and a large bevel gear meshes with the small bevel gear externally. The rotating mechanism also includes an acceleration mechanism.

[0019] The variable diameter drive assembly includes a first lower rack and a second lower rack, with a gap between the first lower rack and the second lower rack. The gap is located between the first detector and the second detector. A third upper rack is provided above the gap. The first lower rack, the third upper rack, and the second lower rack can sequentially drive the acceleration mechanism to make the drum rotate in the forward or reverse direction.

[0020] Furthermore, the acceleration mechanism includes a small gear 1, which is coaxial with a large bevel gear. The small gear 1 is externally meshed with a large gear 1. A coaxial small gear 2 is provided on one side of the large gear 1, which is externally meshed with a large gear 2. The axis of the large gear 2 coincides with that of the small gear 1.

[0021] The mounting box has three through slots that mate with the second large gear, allowing the second large gear to be exposed in three directions.

[0022] Furthermore, the deflection mechanism includes:

[0023] The deflection gear has a third rotating shaft fixed at both ends of the mounting box, and the deflection gear is fixedly sleeved on the third rotating shaft.

[0024] The first deflection rack and the second deflection rack are fixed on the workbench at the position where the non-conforming area is entered by the support frame 2. The second deflection rack is fixed at the position where the non-conforming area is left. The first deflection rack and the deflection gear work together to drive the mounting box to deflect by an angle so that the spiral assembly is vertically downward. The second deflection rack and the deflection gear work together to drive the mounting box to deflect by an angle so that the spiral assembly is restored to a horizontal state.

[0025] Furthermore, both the defective and qualified areas are fixed with feeding racks that cooperate with the rotating mechanism via support frame two. The upper surface of support frame two is equipped with a cylinder, and the cylinder cooperates independently with each feeding rack.

[0026] A control system is provided on one side of the workbench;

[0027] The control system is electrically connected to the cylinder, the first detection and recognition device, and the second detection and recognition device. After the control system reads the detection signal of the recognition device, it controls the corresponding cylinder to start, so that the feeding rack descends and engages with the rotating mechanism, causing the diameter of the sausage casing to shrink, making it easier for the casing to fall off to the corresponding area.

[0028] Furthermore, a second slider is fixed at one end of the third rotating shaft, and a second slide groove that cooperates with the second slider is provided on the worktable. The second slide groove is provided with a third slide groove that corresponds to the positions of the first deflection rack and the second deflection rack. The third slide groove can accommodate the deflection angle of the second slider inside it.

[0029] Furthermore, the workbench is provided with material placement plates on both sides corresponding to the positions of the defective and qualified areas, and a discharge port is provided on the side plate of the workbench so that the defective and qualified areas are connected to the corresponding material placement plates.

[0030] Furthermore, the conveying assembly includes a first rotating shaft rotatably disposed at both ends of the worktable, with pulleys fixedly sleeved at both ends of the first rotating shaft, and a belt drivingly connecting the two pulleys; a motor capable of driving the first rotating shaft to rotate is fixedly disposed on the worktable.

[0031] The belt is fixed with a mounting component, and the mounting box and the mounting component are rotatably connected.

[0032] The present invention has the following beneficial effects:

[0033] 1. This fully automatic sausage casing foreign object detection device uses a winding assembly to evenly wrap long strips of sausage casing around its surface, facilitating foreign object detection. The winding assembly includes a rotating drum and a support rod. The rotating drum is a transparent hollow structure with an internal light source. The light source provides a stable and controllable illumination environment for identifying defects on or inside the sausage casing, eliminating blind spots, magnifying defect features, and improving detection results. The rotation of the rotating drum can control the support rod to move closer to or away from the axis of the rotating drum, making the diameter of the winding assembly variable. This allows the sausage casing to separate from the support rod, thereby enabling the corresponding sausage casing to be unloaded. At the same time, a deflection mechanism is set to drive the winding assembly to deflect vertically, facilitating the unloading of sausage casing.

[0034] 2. This fully automatic sausage casing foreign object detection device is equipped with a first detection identifier, a second detection identifier, a rotating mechanism, and a diameter-changing drive assembly. The diameter-changing drive assembly cooperates with the rotating mechanism to make the drum rotate in the forward or reverse direction. After the first detection, the drum rotates in the reverse direction to change the contact position between the sausage casing and the support rod, and then rotates in the forward direction to make the sausage casing supported by the sausage wrapping assembly. The second detection identifier performs a second detection on the sausage casing whose contact position with the support rod has changed. The second detection is to detect the position of the sausage casing that was covered by the support rod in the first detection to avoid missed detection.

[0035] 3. The fully automatic sausage casing foreign object detection device is equipped with a rotating mechanism, a diameter-changing drive assembly, a feeding rack, a deflection gear, a first deflection rack, and a second deflection rack. The diameter-changing drive assembly and the feeding rack cooperate with the rotating mechanism to enable the sausage casing assembly to rotate while moving horizontally. The first deflection rack and the second deflection rack cooperate with the deflection gear to enable the sausage casing assembly to deflect while moving horizontally.

[0036] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0051] The following is based on Figures 1-11 This invention describes a fully automated sausage casing foreign object detection device provided in an embodiment of the invention.

[0052] Please refer to Figures 1-2 This invention provides a fully automatic sausage casing foreign object detection device, including a workbench 3. The workbench 3 is divided into a detection area 10, a non-conforming area 11, and a conforming area 12. The workbench 3 has material placement plates 132 on both sides corresponding to the positions of the non-conforming area 11 and the conforming area 12. The workbench 3 also has a discharge port 131 on its side plate, so that the non-conforming area 11 and the conforming area 12 are connected to the corresponding material placement plates 132. The sausage casings undergo foreign object detection in the detection area 10, and the non-conforming casings fall into the non-conforming area 11. The worker transfers the non-conforming casings to the corresponding material placement plates 132 through the discharge port 131, while the conforming casings fall into the conforming area 12. The worker transfers the conforming casings to the corresponding material placement plates 132 through the discharge port 131, thus realizing the sorting of sausage casings.

[0053] Sausage casings are the outer packaging of sausages, and their basic function is to ensure that the sausages do not spoil under certain conditions and within a certain time to meet the needs of storage and distribution. This function is provided by the barrier properties of the casings. In existing technologies, casing detection and sorting are mostly carried out after the casing shrinking process. Foreign objects inside the shrinked casing cannot be identified, affecting the identification results. On the other hand, unshrinked casings are too long, making them inconvenient for detection and sorting. Using ordinary pneumatic pushers to push them out or clamps to pick them up results in low accuracy and is very easy to cause mechanical damage to the casings during movement, affecting the barrier properties of the casings.

[0054] Please refer to Figures 1-8 To facilitate foreign object detection on unshrinked long sausage casings, an identifier, a conveying assembly, and a sausage wrapping assembly 4 are provided. The identifier is fixed to the detection area 10 by a support frame 14. The identifier can perform high-precision detection of foreign objects on the surface of the sausage casing. The conveying assembly is located on the workbench 3, and a movable mounting box 6 is installed on the conveying assembly. The sausage wrapping assembly 4 is installed on the mounting box 6. The sausage wrapping assembly 4 moves with the conveying assembly, passing through the detection area 10, the unqualified area 11, and the qualified area 12 in sequence. By rotating the sausage wrapping assembly 4, the long sausage casing can be evenly wrapped around its surface. The sausage wrapping assembly 4 includes a rotating cylinder 41, which is a transparent hollow structure with a light source inside. The light source provides a stable and controllable lighting environment for the identification of defects on the surface or inside of the sausage casing, eliminating blind spots and amplifying defect features. It is a core auxiliary condition for achieving accurate and efficient detection. When the sausage wrapping assembly 4 passes the identifier, it can perform all-round accurate detection of the sausage casing on its surface.

[0055] To facilitate the sorting and unloading of unshrinked long sausage casings, multiple support rods 42 are evenly arranged circumferentially on the outside of the rotating drum 41. The rotating mechanism drives the rotating drum 41 to rotate, which can control the support rods 42 to move closer to or away from the axis of the rotating drum 41, so that the sausage winding assembly 4 can rotate with different diameters, which facilitates the separation and unloading of the sausage casing from the support rods 42. A deflection mechanism 7 is also provided. The deflection mechanism 7 can drive the sausage winding assembly 4 to deflect vertically through the mounting box 6, which facilitates the unloading of the sausage casing.

[0056] Specifically, multiple sausage casing assemblies 4 are mounted on mounting boxes 6, enabling simultaneous foreign object detection and sorting of multiple casings. The rotating mechanism is independent for each sausage casing assembly 4, allowing each assembly to rotate independently. The number of mounting boxes 6 on the conveyor assembly cannot affect the deflection of the sausage casing assembly 4 in the non-conforming area 11 and the conforming area 12 (e.g., ...). Figure 1 (As shown) There are two mounting boxes 6 here. Their meeting point as they move with the conveyor components is in the middle of the workbench 3, while the defective area 11 and the qualified area 12 are in the rear half of the workbench 3. Therefore, the two will not affect each other and can be alternately detected and sorted, improving efficiency.

[0057] In addition, a guide ring 15 is provided at one end of the workbench 3 near the detection area 10. The long strip of sausage casing passes through the guide ring 15 and wraps around the sausage wrapping assembly 4 to avoid sausage casing tangling.

[0058] However, when the casing is wrapped around the casing assembly 4, the contact position between the casing and the support rod 42 is fixed. During the subsequent foreign object detection process, the support rod 42 will continuously block the light at the contact position with the casing, resulting in limited detection effectiveness at the contact position and frequent missed detections.

[0059] Please refer to Figures 1-3 To this end, the identifier is equipped with a first detection identifier 1 and a second detection identifier 2. The first detection identifier 1, in conjunction with a light source, performs a first detection on the non-contact position between the casing and the support rod 42. A diameter-changing drive assembly 9 is provided below the identifier. The diameter-changing drive assembly 9 cooperates with the rotating mechanism to make the rotating drum 41 rotate in the forward or reverse direction. The reverse rotation of the rotating drum 41 can change the contact position between the casing and the support rod 42. Then, it rotates in the forward direction to make the casing-wrapping assembly 4 support the casing. The second detection identifier 2 is used to perform a second detection on the casing after changing the contact position between the casing and the support rod 42. The second detection is to detect the position of the casing that was covered by the support rod 42 in the first detection to avoid missed detection.

[0060] It should be noted that the angle of forward rotation of the above-mentioned sausage wrapping assembly 4 is smaller than that of reverse rotation, so that the sausage wrapping assembly 4 can support the sausage casing while changing the contact position between the sausage casing and the support rod 42.

[0061] Please refer to Figure 5 and Figure 8In order to achieve the connection between the rotating cylinder 41 and the support rod 42, a connecting rod 43 is hinged between the rotating cylinder 41 and each support rod 42. A second rotating shaft 47 is fixed at one end of the rotating cylinder 41 near the mounting box 6. The second rotating shaft 47 is rotatably mounted on the mounting box 6. Driving the second rotating shaft 47 will drive the rotating cylinder 41 to rotate.

[0062] To facilitate the rotation of the rotating drum 41 and control the support rod 42 to move closer to or away from the axis of the rotating drum 41, the sausage assembly 4 also includes a disc 44 and a first slide groove 45. The disc 44 is rotatably mounted on the second rotating shaft 47 and is rotatably connected to the mounting box 6 and has damping. The first slide groove 45 is evenly opened on the surface of the disc 44 along the circumference. The end of the support rod 42 near the disc 44 is provided with a first slider 46 that cooperates with the first slide groove 45. The distances from the two ends of the first slide groove 45 to the axis of the disc 44 are different. The rotation of the rotating drum 41 pushes the first slider 46 to slide in the first slide groove 45 to change the distance between the support rod 42 and the axis of the rotating drum 41, so that the diameter of the sausage assembly 4 can be changed. When the rotating drum 41 rotates in the forward or reverse direction, the first slider 46 will slide to one end of the first slide groove 45. When the rotating drum 41 continues to rotate in the forward or reverse direction, the sausage assembly 4 will continue to rotate with the maximum or minimum diameter.

[0063] Specifically, there is damping between the disc 44 and the mounting box 6, which allows the first slider 46 to slide within the first slide groove 45 without causing the disc 44 to rotate. Only when the first slider 46 slides to one end of the first slide groove 45 and continues to rotate in a fixed direction will it drive the disc 44 to rotate synchronously with the rotating cylinder 41.

[0064] Please refer to Figures 5-8 and Figure 11 To facilitate foreign object detection, the rotating mechanism includes a small bevel gear 51, which is coaxial with the rotating drum 41 and fixedly sleeved outside the second rotating shaft 47. A large bevel gear 52 meshes with the small bevel gear 51. The rotating mechanism also includes an acceleration mechanism. A variable diameter drive assembly 9 is located in and near the detection area 10 and can drive the rotating mechanism to rotate. The variable diameter drive assembly 9 includes a first lower rack 91 and a second lower rack 92. 92 is mounted on the workbench 3 via a support frame 94. There is a blank section between the first lower rack 91 and the second lower rack 92. The blank section is located between the first detector 1 and the second detector 2. A third upper rack 93 is provided above the blank section. The first lower rack 91, the third upper rack 93 and the second lower rack 92 can sequentially drive the acceleration mechanism to make the rotating drum 41 rotate in the forward or reverse direction. When the third upper rack 93 meshes with the acceleration mechanism, there is a blank section below the acceleration mechanism, and the first lower rack 91 and the second lower rack 92 will not mesh with the acceleration mechanism.

[0065] Specifically, the first lower rack 91 and the second lower rack 92 are used to drive the rotating mechanism to rotate forward. The rotating drum 41 rotates forward so that the sausage wrapping assembly 4 rotates at its maximum diameter, which can wrap the sausage casing to its surface and rotate during the detection process, so that the sausage casing is fully exposed to the identifier. The third upper rack 93 is used to drive the rotating mechanism to rotate in the opposite direction. The rotating drum 41 rotates in the opposite direction so that the sausage wrapping assembly 4 rotates a small distance at its minimum diameter. At this time, the support rod 42 separates from the sausage casing and rotates asynchronously. Then the rotating drum 41 rotates forward again so that the support rod 42 contacts the sausage casing. The contact position between the sausage casing and the support rod 42 changes, and the sausage wrapping assembly 4 continues to move. The second detection identifier 2 will perform a second detection on the sausage casing. The variable diameter drive assembly 9 and the rotating mechanism cooperate to make the sausage wrapping assembly 4 complete the rotation work while moving horizontally.

[0066] Furthermore, the acceleration mechanism is equipped with a pinion 53, which is coaxial with a large bevel gear 52. A large gear 54 meshes with the pinion 53 externally. A coaxial pinion 55 is provided on one side of the large gear 54, and a large gear 56 meshes with the pinion 55 externally. The axis of the large gear 56 coincides with that of the pinion 53. The first lower rack 91, the second lower rack 92, and the third upper rack 93 mesh with the large gear 56. During the horizontal movement of the spiral assembly 4, the first lower rack 91, the third upper rack 93, and the second lower rack 92 sequentially mesh with the large gear 56. 56 meshes, driving the large gear 2 56 to rotate in the forward or reverse direction. The rotation of the large gear 2 56 drives the small gear 2 55 to rotate. The rotation of the small gear 2 55 and the large gear 1 54 generate a meshing force, driving the large gear 1 54 to rotate. The large gear 1 54 then drives the small gear 1 53 to rotate. The rotation of the small gear 1 53 causes the large bevel gear 52 to rotate through the central shaft, causing the small bevel gear 51 to rotate. In turn, the rotating drum 41 rotates in the forward or reverse direction. The multiple gears of the acceleration mechanism enable the spiral assembly 4 to achieve rapid spiral work with limited horizontal movement distance, avoiding the worktable 3 from being too long.

[0067] It should be noted that the central shaft of pinion 53 and the central shaft of large bevel gear 52 are the same, while the central shaft of large gear 56, although it coincides with the central shaft axis of pinion 53, is not the same. All of the above central shafts are rotatably mounted on the mounting box 6.

[0068] Additionally, refer to Figure 7 and Figure 11 The mounting box 6 has three through slots 62 that mate with the large gear 56, so that the large gear 56 is exposed in three directions, allowing it to mesh with the first lower rack 91, the third upper rack 93, and the second lower rack 92 respectively.

[0069] Please refer to Figure 1 , Figure 4 and Figure 5To facilitate the vertical deflection of the sausage coil assembly 4 and make it easier to unload, the deflection mechanism 7 is equipped with a deflection gear 73, a first deflection rack 71, and a second deflection rack 72. The mounting box 6 has a third rotating shaft 61 fixed at both ends. The deflection gear 73 is fixedly sleeved on the third rotating shaft 61. The first deflection rack 71 is fixed on the workbench 3 at the position of entering the unqualified area 11 through the support frame 2 14. The second deflection rack 72 is fixed at the position of leaving the qualified area 12. The first deflection rack 71 and the deflection gear 73 work together to drive the mounting box 6 to deflect the angle so that the sausage coil assembly 4 is vertically downward. The second deflection rack 72 and the deflection gear 73 work together to drive the mounting box 6 to deflect the angle so that the sausage coil assembly 4 returns to a horizontal state.

[0070] Specifically, after being detected by the identifier, the sausage casing moves into the non-conforming area 11 along with the sausage winding assembly 4. The first deflecting rack 71 meshes with the deflecting gear 73, causing the deflecting gear 73 to rotate 90° in the opposite direction. This causes the mounting box 6 to deflect, causing the sausage winding assembly 4 to move vertically downward. When the diameter of the sausage winding assembly 4 decreases, the sausage casing on its surface can easily fall into the non-conforming area 11 or the conforming area 12. The sausage winding assembly 4 moves away from the conforming area 12, and the second deflecting rack 72 meshes with the deflecting gear 73, causing the deflecting gear 73 to rotate 90° in the forward direction. This causes the mounting box 6 to deflect, causing the sausage winding assembly 4 to return to a horizontal state.

[0071] It should be noted that the casing wrapped around the sausage coil assembly 4 is long enough and tightly packed. When the sausage coil assembly 4 is vertically downward and its diameter is still at its maximum, the casing will not separate directly from the sausage coil assembly 4.

[0072] Please refer to Figure 1 and Figure 4 To reduce the diameter of the sausage casing 4 in the corresponding area, a feeding rack 8 that cooperates with the rotating mechanism is fixed on both the defective area 11 and the qualified area 12 by a support frame 2 14. A cylinder 16 is provided on the upper surface of the support frame 2 14. The cylinder 16 and each feeding rack 8 are independently engaged. A control system 18 is provided on one side of the workbench 3. The control system 18 is electrically connected to the cylinder 16, the first detection identifier 1, and the second detection identifier 2. After the control system 18 reads the detection signal of the identifier, it controls the corresponding cylinder 16 to start, so that the feeding rack 8 descends and engages with the rotating mechanism, thereby reducing the diameter of the sausage casing 4, making it easier for the casing to fall off into the defective area 11 or the qualified area 12.

[0073] Specifically, the feeding rack 8 meshes with the large gear 56. The three through slots 62 on the mounting box 6 allow the large gear 56 to be exposed in three directions. After the spiral assembly 4 is vertically deflected, the feeding rack 8 can mesh with the large gear 56.

[0074] Please refer to Figure 1 and Figure 9To ensure the spiral assembly 4 remains stable in a vertical or horizontal position, a second slider 63 is fixed to one end of the third rotating shaft 61. A second groove 64 that mates with the second slider 63 is provided on the worktable 3. As the mounting box 6 moves with the conveying assembly, the second slider 63 slides stably within the second groove 64, ensuring the spiral assembly 4 remains stable in a vertical or horizontal position. The second groove 64 is provided with a third groove 641 that corresponds to the positions of the first deflection rack 71 and the second deflection rack 72. The third groove 641 can accommodate the deflection angle of the second slider 63 within it. When the deflection gear 73 meshes with the first deflection rack 71 and the second deflection rack 72, the second slider 63 can rotate within the third groove 641.

[0075] Specifically, the longitudinal section of the second slider 63 is approximately square, and it can slide stably within the second slide groove 64 before and after a 90° deflection. Furthermore, two sides of the second slider 63 are arc-shaped, allowing it to slide through the arc-shaped grooves at both ends of the second slide groove 64.

[0076] Please refer to Figure 10 To facilitate the installation of the mounting box 6, the transmission assembly here includes a first rotating shaft 31 rotatably mounted at both ends of the workbench 3. Pulleys 32 are fixedly sleeved at both ends of the first rotating shaft 31. A belt 33 is connected between the two pulleys 32. A motor 34 capable of driving the first rotating shaft 31 to rotate is fixed on the workbench 3. A mounting part 17 is fixed on the belt 33. The mounting box 6 and the mounting part 17 are rotatably connected.

[0077] Winding stage: The conveyor assembly is activated to move the sausage winding assembly 4 along with it, passing through the detection zone 10, the unqualified zone 11 and the qualified zone 12 in sequence. One end of the long strip of sausage casing is passed through the guide ring 15 and wound onto the sausage winding assembly 4. During the movement of the sausage winding assembly 4, the first lower rack 91 first meshes with the large gear 56, and drives the large bevel gear 52 to rotate rapidly through the acceleration mechanism, which in turn drives the small bevel gear 51 to rotate, causing the rotating drum 41 to rotate in the forward direction. The forward rotation of the rotating drum 41 causes the sausage winding assembly 4 to rotate at its maximum diameter, which can wind the sausage casing onto its surface.

[0078] Detection Phase: After winding is completed, the sausage casing assembly 4 moves below the first detection and identification device 1. The first detection and identification device 1, in conjunction with the light source, performs the first detection on the non-contact area between the casing and the support rod 42. During the detection process, the first lower rack 91 is always engaged with the second large gear 56, driving the sausage casing assembly 4 to rotate in the forward direction, so that the casing is fully exposed to the first detection and identification device 1. After the first detection is completed, the third upper rack 93 is engaged with the second large gear 56, driving the rotating drum 41 to rotate in the reverse direction, so that the sausage casing assembly 4 rotates a small distance with the smallest diameter. At this time, the support rod 4... 2. The casing separates from the casing and rotates asynchronously. Then, the rotating drum 41 rotates forward again, causing the support rod 42 to contact the casing, changing the contact position between the casing and the support rod 42. After the contact position between the casing and the support rod 42 changes, the casing winding assembly 4 continues to move. The second detection and identification device 2 will perform a second detection on the casing, that is, detect the position of the casing that was covered by the support rod 42 in the first detection, to avoid missed detection. During the detection process, the second lower rack 92 meshes with the large gear 2 56 to drive the casing winding assembly 4 to rotate forward, so that the casing is fully exposed to the second detection and identification device 2.

[0079] Sorting Stage: After being detected by the identifier, the sausage casings move into the non-conforming area 11 along with the sausage winding assembly 4. The first deflecting rack 71 first meshes with the deflecting gear 73, causing the deflecting gear 73 to rotate 90° in the opposite direction, thus causing the mounting box 6 to deflect and the sausage winding assembly 4 to move vertically downward. In the non-conforming area 11, the control system 18 reads the non-conforming signal from the identifier and controls the corresponding cylinder 16 to start, causing the feeding rack 8 to descend and mesh with the large gear 56, driving the rotating drum 41 of the non-conforming sausage casings to rotate in the opposite direction, thereby reducing the diameter of the corresponding sausage winding assembly 4, causing the non-conforming sausage casings to fall into the non-conforming area 11. In the conforming area 12, the control system 18 reads the conforming signal from the identifier and controls the corresponding cylinder 16 to start, causing the feeding rack 8 to descend and mesh with the large gear 56, driving the rotating drum 41 of the conforming sausage casings to rotate in the opposite direction, thereby reducing the diameter of the corresponding sausage winding assembly 4, causing the conforming sausage casings to fall into the conforming area 12, thus realizing the sorting of sausage casings.

[0080] The spiral assembly 4 moves away from the qualified area 12. The second deflection rack 72 meshes with the deflection gear 73, causing the deflection gear 73 to rotate 90° in the forward direction. This causes the mounting box 6 to deflect at an angle, which in turn causes the spiral assembly 4 to return to a horizontal state. The spiral assembly 4 continues to move with the conveyor assembly, waiting to participate in the next round of testing.
