Description

Technical Field

[0001] The invention belongs to the technical field of livestock slaughtering line equipment, in particular to an automatic track changing mechanism for a livestock slaughtering line. Background Art

[0002] With the development of animal husbandry, the scale of slaughterhouses continues to expand, and the requirements for livestock slaughter efficiency are becoming increasingly higher. Livestock slaughter lines can effectively improve slaughtering efficiency and reduce labor intensity. In slaughter lines, carcasses are usually transported to different warehouses by classification. The pulley hooks holding the carcasses need to be transferred from the straight pipe track to the branch pipe track. When shipping, they need to be transferred from the branch pipe track back to the main pipe track. This requires an automatic track change mechanism to achieve fast and accurate track changes to improve the efficiency of the entire assembly line.

[0003] A Chinese invention patent publication numbered CN111646133A discloses an automatic track-changing mechanism for a livestock slaughtering assembly line, comprising an inlet straight guide rail, an outlet straight guide rail, an elbow, a swing arm, and a swing arm drive mechanism. The inlet straight guide rail and the outlet straight guide rail are in the same straight line, with their free ends arranged opposite to each other. The elbow is located on one side of the outlet straight guide rail. One end of the swing arm is movably connected to the end of the inlet straight guide rail and is free to swing relative to the inlet straight guide rail. When the swing arm swings to a first extreme position and a second extreme position, it is clamped and connected to the free end of the outlet straight guide rail and the free end of the elbow, respectively. The swing arm drive mechanism is placed on the side of the swing arm and is used to push the swing arm to swing freely back and forth between the first extreme position and the second extreme position. The livestock slaughtering assembly line effectively improves the accuracy and speed of track changing, thereby improving the production efficiency of the entire assembly line, and thus has high applicability.

[0004] However, the above technology often has the following defects: the swing arm drive mechanism it adopts is placed on the side of the swing arm and drives the swing arm to swing. After long-term use, this side drive method is prone to cause the swing arm swing trajectory to deviate due to uneven force. Moreover, the circulating tracks are mostly independent circulating structures. The livestock on each track can only run along the existing track and cannot switch freely between multiple tracks, which easily leads to the need for multiple repetitive construction in the construction of livestock tracks.

[0005] To this end, the present invention provides an automatic track changing mechanism for a livestock slaughtering production line. Summary of the Invention

[0012] One end of the traction rope extends into the conveying cavity inside the linear track, and the other end of the traction rope extends to the surface of the arc track. The outer arc surfaces of the two guide wheels are slidably connected to the inner wall of the linear track.

[0018] 1. The triangular transmission structure composed of a synchronous belt and a transmission wheel can transmit power stably and efficiently, driving the line components to move continuously, reducing the loss during power transmission, and ensuring the continuous operation of the slaughtering line. During the track change process, the coordination of the traction rope, torsion spring and rotating plate can quickly adjust the direction of the line components.

[0019] 2. Through the active connection between the L-shaped moving seat and the outer protruding edge of the synchronous belt, and the connection between the clamping teeth on the base and the ratchet groove of the outer protruding edge, the connection between the line component and the synchronous belt is enhanced, and slipping is avoided. The guide wheel rolls along the inner wall of the track during movement, which not only plays a guiding role, but also disperses gravity and impact force, reducing the wear of components. In addition, the swing blades and the annular wheel cooperate with the lock column and the notch to accurately limit the position of the guide assembly, ensuring the coordination of the movements of various components during the track change process, reducing the probability of safety hazards such as derailment, and ensuring the stability of the mechanism operation.

[0020] 3. The sensor in the guide assembly can detect the position of the line assembly in real time and trigger the track change action in time. The meshing transmission of gear A and gear B ensures the accuracy of power transmission. The cam drives the distribution plate to swing precisely through the moving groove. Its curved surface can exert accurate lateral thrust on the L-shaped moving seat, guiding the line assembly to change track according to the preset trajectory. The hook end of the convex cone plate is next to the moving path of the line assembly during track change, further assisting in positioning. Combined with the steering of the guide wheel driven by the rotating plate, precise switching from linear track to curved track or vice versa is achieved, effectively avoiding track change deviation.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figures 1 to 10 As shown, the embodiment of the present invention includes a linear track 1, the upper surface of the linear track 1 is provided with an L-shaped limit end 101, the bottom of the surface of the linear track 1 is provided with a receiving bottom surface 102, a conveying cavity is provided between the linear track 1 and the receiving bottom surface 102, the upper end surface of the receiving bottom surface 102 is abutted against the arc-shaped track 2, the lower surface of the arc-shaped track 2 is provided with a fitting surface 201, the lower surface of the fitting surface 201 is placed on the receiving bottom surface 102, a ring groove A105 is provided in the middle of one side surface of the linear track 1, a conveying wheel 3 is movably connected to the conveying cavity of the linear track 1 through a rotating shaft, the outer arc surface of the conveying wheel 3 is movably sleeved with a synchronous belt 4, and an outer protrusion 40 is provided at the edge of one side surface of the synchronous belt 4. 1. One end of the outer protrusion 401 is movably connected to the circuit assembly 5. The circuit assembly 5 includes an L-shaped movable seat 51 that is movably connected to the outer protrusion 401 on the surface of the synchronous belt 4. A connector 511 is provided on one end face of the L-shaped movable seat 51. A mounting groove is provided in the middle of the front of the connector 511. The upper surface of the connector 511 abuts against the lower surface of the supporting bottom surface 102. A base 52 is provided on the side of the L-shaped movable seat 51 away from the connector 511. A bottom groove is provided on one side of the upper surface of the base 52. Clamping teeth 522 are provided on both sides of the inner side wall of the bottom groove on the upper surface of the base 52. A ratchet groove is provided on one side of the clamping tooth 522. One side of the clamping tooth 522 is connected to the outer protrusion 401.

[0035] The linear track 1 mainly undertakes the linear conveying function and provides basic track support for the stable movement of the line component 5. The supporting bottom surface 102 at the bottom of its surface forms a conveying cavity with itself. The cavity provides space for the installation and movement of the conveying wheel 3, the synchronous belt 4 and the line component 5. The L-shaped limit end 101 on the upper surface can play a lateral limit role for the line component 5 during the movement process, preventing it from leaving the track due to shaking or uneven force during linear conveying. The outer arc surface of the guide wheel 53 of the line component 5 is slidably connected to the inner wall of the linear track 1, rolling along the inner wall, and cooperating with the drive of the synchronous belt 4, so that the line component 5 moves linearly along the linear track 1, thereby realizing stable conveying of the hook and carcass.

[0036] The function of the curved track 2 is to realize the turning of the line. The fitting surface 201 of its lower surface is placed on the supporting bottom surface 102 of the linear track 1, which ensures the stability of the connection with the linear track 1 and also determines the reference position of the turning. When it is necessary to change the track from the linear track 1 to the curved track 2, the line component 5 changes its direction under the action of the traction rope 57, the torsion spring 563 and the rotating plate 54. The guide wheel 53 gradually transitions from the inner wall of the linear track 1 to the inner wall of the curved track 2. The curvature of the curved track 2 is adapted to the turning trajectory of the guide wheel 53. The inner wall guides the guide wheel 53, forcing the line component 5 to move along the curved path, thereby driving the hook and the carcass to complete the transition from linear motion to curved motion, thereby realizing the change of track to the curved track 2.

[0037] In addition, a reference surface 103 is provided at the intersection of the linear track 1 and the curved track 2. The reference surface 103 provides an installation basis for the guide component 6, ensuring that the guide component 6 can accurately play a role at the intersection of the two tracks. When the line component 5 passes through the intersection, the respective track profiles of the linear track 1 and the curved track 2 provide a reference for the movement of guide components such as the distribution plate 69 and the convex cone plate 64, so that these components can accurately guide the line component 5 into the target track, ensuring the smoothness and accuracy of the track change process. When it is necessary to change tracks from the curved track 2 back to the linear track 1, the curved track 2 also guides the line component 5 to gradually adjust its direction through its track structure, and finally makes the guide wheel 53 re-enter the inner wall of the linear track 1, completing the transition from curved motion to linear motion.

[0038] like Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, there are three transmission wheels 3, two of which are symmetrically installed on both sides of the upper surface of the linear track 1, and the transmission wheel 3 on the other side is movably connected to the surface of the arc track 2 through a rotating shaft. The synchronous belt 4 is sleeved on the surface of the transmission wheel 3 to form a triangular structure. A guide wheel 53 is slidably abutted inside the conveying cavity of the linear track 1, and a rotating plate 54 is movably connected to the middle part of the lower surface of the guide wheel 53 through a rotating shaft. Two guide wheels 53 are connected to both sides of the upper surface of the rotating plate 54, and a U-shaped plate 55 is movably connected to the lower surface of the rotating plate 54 through a rotating shaft in the middle. Folding edges 551 are provided on both sides of the lower surface of the U-shaped plate 55, and the upper end surface of the folding edge 551 is fixed with a connecting bracket 56 by bolts. A vertical surface 561 is provided at the edge of one side surface of the bracket 56, and a shaft rod 562 is connected to the surface of one side of the vertical surface 561. A torsion spring 563 is sleeved on one side of the outer arc surface of the shaft rod 562. One end of the torsion spring 563 is fixedly installed on the connecting bracket 56, and the other end of the torsion spring 563 is fixedly installed on the rotating plate 54. A traction rope 57 is sleeved on the outer arc surface of the shaft rod 562, and a concave groove 564 is provided on the top of the back side of the connecting bracket 56. One end of the traction rope 57 passes through the outside of the concave groove 564, and one end of the traction rope 57 extends to the conveying cavity inside the linear track 1, and the other end of the traction rope 57 extends to the surface of the curved track 2. The outer arc surfaces of the two guide wheels 53 are slidably connected to the inner wall of the linear track 1.

[0039] The outer arc surface of the synchronous belt 4 is movably connected to the three transmission wheels 3 to form a triangular transmission structure. When the transmission wheels 3 rotate under the action of the driving device, the synchronous belt 4 is driven by friction to perform a circular motion, and the power is stably transmitted to the line component 5. The outer protrusion 401 at the edge of the surface of one side of the synchronous belt 4 is connected to the line component 5. It not only provides a clamping point for the L-shaped moving seat 51, but also cooperates with the ratchet groove of the clamping teeth 522 on the base 52 to form a firm transmission connection, ensuring that the movement of the synchronous belt 4 can be efficiently converted into the moving power of the line component 5, avoiding slippage or power loss, and ensuring the continuity and stability of the transportation process.

[0040] The line component 5 is the main body that carries and drives the hook and carcass to move. It is connected to the outer protrusion 401 through a movable clamp on the L-shaped moving seat 51, directly receiving the power transmitted by the synchronous belt 4, and driving the entire line component 5 to move along the track. The upper surface of the connecting head 511 abuts against the lower surface of the supporting bottom surface 102. On the one hand, it plays an auxiliary supporting role for the line component 5. On the other hand, it limits its up and down displacement through contact with the supporting bottom surface 102 to ensure a smooth movement process. The base 52 is tightly connected to the outer protrusion 401 through the clamping teeth 522, which further enhances the transmission stability between the line component 5 and the synchronous belt 4, and prevents relative displacement when carrying a heavier carcass.

[0041] The guide wheel 53 is a line component 5 whose outer arc surface is slidably connected to the inner wall of the track and rolls along the inner wall during movement. When the line component 5 moves along the linear track 1, the guide wheel 53 limits its lateral deviation by contacting the inner wall of the linear track 1, thereby ensuring the accuracy of linear transportation. During the track changing process, as the rotating plate 54 rotates, the guide wheel 53 transitions from the inner wall of the linear track 1 to the inner wall of the curved track 2. By fitting with the inner walls of different tracks, the line component 5 is guided to move along the contour of the target track, thereby achieving smooth switching of tracks.

[0042] When it is necessary to change tracks, the traction rope 57 is pulled or relaxed under the action of an external driving force, and the torsion spring 563 is deformed or reset through the shaft 562, thereby driving the rotating plate 54 to rotate around the rotating shaft connected to the U-shaped plate 55. The rotation of the rotating plate 54 changes the direction of the guide wheel 53, so that the line component 5 obtains the power and direction guidance for steering, and cooperates with the continuous drive of the synchronous belt 4 to realize the transition from linear motion to curved motion or vice versa. The elastic action of the torsion spring 563 can provide buffering and reset force when the tension of the traction rope 57 changes, thereby ensuring the smoothness of the steering process and avoiding damage to components or track deviation due to sudden force.

[0043] The synchronous belt 4 efficiently transmits power to the line component 5 through the outer protrusion 401, providing continuous driving force for its movement. The line component 5 receives power through the L-shaped moving seat 51 and the base 52, relies on the guide wheel 53 to achieve precise guidance, and completes the track switching with the help of the steering adjustment mechanism.

[0044] like Figure 7 and Figure 8As shown, a reference surface 103 is provided at the intersection of the linear track 1 and the arc track 2, and a guide assembly 6 is connected through the upper surface of the reference surface 103. The guide assembly 6 includes a gear A61 rotatably connected to the bottom of the reference surface 103, and the upper surface of the gear A61 is movably connected to a swinging wing 62 through a rotating shaft. An extension end is provided on one side of the outer arc surface of the swinging wing 62, and a lock column 621 is provided on the surface of the extended end of one side of the swinging wing 62. An annular wheel 63 is fixedly installed in the middle of the lower surface of the gear A61, and a notch 631 is provided on one side of the lower surface of the annular wheel 63. The inner arc surface of the notch 631 is movably engaged with the lock column 621, and the upper surface of the swinging wing 62 is connected to an outer convex cone plate 64, and a hook end 641 is provided on one side of the outer arc surface of the outer convex cone plate 64. A sensor 66 is fixedly installed on the surface of the end 641, and a shift post 642 is provided on the side of the upper surface of the convex cone plate 64 away from the bent hook end 641. The outer arc surface of the gear A61 is meshed with the gear B67, and the upper surface of the gear B67 is movably connected to the cam 68 through a rotating shaft. A movable groove 681 is provided in the upper surface of the cam 68, and a distribution plate 69 is slidably engaged with the inner arc surface of the movable groove 681. A curved surface 691 is provided on one side of the distribution plate 69, and an edge of one side of the distribution plate 69 is movably connected to the reference surface 103 through a rotating shaft. An arc groove 104 is provided on the surface of the reference surface 103 close to the convex cone plate 64. The shift post 642 passes through the reference surface 103 and is slidably engaged into the arc groove 104. The distribution plate 69 is adapted to the L-shaped movable seat 51.

[0045] When the line assembly 5 approaches the track intersection, the sensor 66 on the convex cone plate 64 detects a signal and transmits it to the control system. The control system drives gear A61 to rotate. Since gear A61 and gear B67 are engaged with each other, the rotation of gear A61 will drive gear B67 to rotate synchronously, transmitting power to the subsequent guide execution components, providing power support for the action of the entire guide assembly 6.

[0046] The swinging wing 62, the annular wheel 63 and the convex cone plate 64 jointly assume the functions of auxiliary positioning and preliminary guidance. When the gear A61 rotates, the annular wheel 63 on its lower surface rotates accordingly, and the notch 631 on the annular wheel 63 and the lock column 621 of the swinging wing 62 move relative to each other. When the lock column 621 slides into the notch 631, it will drive the swinging wing 62 to swing around the rotating shaft connected to the gear A61, and then make the convex cone plate 64 on the upper surface of the swinging wing 62 swing synchronously. The shifting post 642 on the convex cone plate 64 slides in the arc groove 104 of the reference surface 103 to limit the swing amplitude and trajectory, ensuring that the hook end 641 of the convex cone plate 64 can be accurately located next to the moving path of the line component 5. Through physical blocking and guidance, it provides preliminary direction guidance for the line component 5 to avoid its offset at the intersection.

[0047] When gear B67 rotates, the cam 68 on its upper surface rotates accordingly, and the moving groove 681 on the cam 68 slides and engages with the distribution plate 69. As the cam 68 rotates, the moving groove 681 pushes the distribution plate 69 to swing around the rotating shaft connected to the reference surface 103. When it is necessary to change tracks to the curved track 2, the distribution plate 69 swings in the direction of the curved track 2, and its curved surface 691 contacts the L-shaped moving seat 51 of the line component 5, guiding the L-shaped moving seat 51 to turn to the curved track 2 through lateral thrust. When it is necessary to change tracks to the linear track 1, the distribution plate 69 swings in the direction of the linear track 1, guiding the line component 5 to return to the linear track. The swing angle and timing of the distribution plate 69 precisely match the moving position of the line component 5, ensuring the accuracy of the track change direction.

[0048] Sensor 66 plays the role of signal detection and triggering in the guide component 6. It can detect the position information of the line component 5 in real time. When the line component 5 reaches the preset track change preparation position, the sensor 66 transmits the signal to the control system. The control system then drives gear A61 and gear B67 to rotate according to the track change requirements, thereby starting the guiding action of the entire guide component 6, realizing the automation and precise triggering of the track change process.

[0049] The guide assembly 6 transmits power to each actuator through gear transmission, uses the swinging blades 62 and the convex cone plate 64 for preliminary positioning and guidance, uses the cam 68 and the distribution plate 69 to achieve precise direction switching, and then realizes automatic triggering through the sensor 66. The various components work together to ensure the direction accuracy and stability of the line assembly 5 during the track change process.

[0050] like Figures 1 to 9 As shown, the specific working process:

[0051] In normal working state, the transmission wheel 3 is continuously rotated under the drive of the driving device. Since the outer arc surface of the synchronous belt 4 is movably sleeved on the three transmission wheels 3 and forms a triangular structure, the rotation of the transmission wheel 3 will smoothly drive the synchronous belt 4 to circulate. The outer protrusion 401 on the edge of the surface of one side of the synchronous belt 4 is movably engaged with the L-shaped moving seat 51 in the line component 5. At the same time, the clamping teeth 522 on the base 52 are tightly connected with the outer protrusion 401 through the ratchet groove. When the synchronous belt 4 moves, it can stably drive the line component 5 to move along the track as a whole. When the linear track 1 is moved, the upper surface of the connector 511 on one side of the L-shaped movable seat 51 abuts against the lower surface of the supporting bottom surface 102, and moves along the track direction with the movement of the synchronous belt 4, while the outer arc surfaces of the guide wheels 53 connected on both sides of the upper surface of the rotating plate 54 are slidably connected to the inner wall of the linear track 1. During the movement, the guide wheels 53 will roll along the inner wall of the linear track 1. On the one hand, it can accurately guide the movement of the line component 5 to prevent it from deviating from the track direction. On the other hand, it can also disperse the gravity and impact force on the line component 5 to ensure the stability of the overall movement.

[0052] When a track change operation is required, the external control system sends a track change signal from the linear track 1 to the curved track 2, and the traction device starts working, pulling the traction rope 57. The traction rope 57 is connected to the outer arc surface of the shaft 562, and one end of the traction rope extends to the surface of the curved track 2. Under the action of tension, the traction rope 57 drives the shaft 562 to rotate, thereby causing the torsion spring 563 on the shaft 562 to deform. Since one end of the torsion spring 563 is fixed to the connecting bracket 56 and the other end is fixed to the rotating plate 54, the deformation of the torsion spring 563 will generate a reverse force, which, in conjunction with the tension of the traction rope 57, drives the rotating plate 54 to rotate around the rotating shaft connected to the U-shaped plate 55. The rotation of the rotating plate 54 will change the direction of the guide wheel 53, thereby adjusting the overall direction of the line assembly 5, causing it to gradually deflect toward the curved track 2.

[0053] During this process, when the line component 5 approaches the intersection of the linear track 1 and the curved track 2, the sensor 66 on the convex cone plate 64 will detect the approach signal of the line component 5 and transmit the signal to the control system. The control system then drives gear A61 to start rotating, and gear A61 and gear B67 engage with each other. The rotation of gear A61 drives gear B67 to rotate synchronously. The cam 68 connected to the upper surface of gear B67 through the rotating shaft rotates with gear B67, and the movable groove 681 on the cam 68 slides and engages with the distribution plate 69. As the cam 68 rotates, the movable groove 681 will push the distribution plate 69 to swing upward with the rotating shaft connected to the reference surface 103 as the center, so that the curved surface 691 of the distribution plate 69 is facing the direction of the curved track 2.

[0054] At the same time, when the gear A61 rotates, the annular wheel 63 fixed in the middle of its lower surface also rotates accordingly. The notch 631 on the lower surface of the annular wheel 63 will move relative to the lock column 621 on the extended end surface of the swinging wing 62. When the lock column 621 slides from the non-notch 631 of the annular wheel 63 into the notch 631, it will drive the swinging wing 62 to swing around the rotating shaft connected to the gear A61. The convex cone plate 64 connected to the upper surface of the swinging wing 62 also swings accordingly. The shifting column 642 on the convex cone plate 64 slides in the arc groove 104 of the reference surface 103, which limits and guides the swinging of the swinging wing 62, so that the bent hook end 641 of the convex cone plate 64 is just next to the moving path of the line component 5, thereby helping to guide the direction of the line component 5.

[0055] At this time, the line component 5 continues to move driven by the synchronous belt 4. When the L-shaped moving seat 51 moves to the intersection, the distribution plate 69 will contact the L-shaped moving seat 51. Since the distribution plate 69 has swung toward the arc track 2, its curved surface 691 will generate a lateral thrust on the L-shaped moving seat 51, guiding the L-shaped moving seat 51 to gradually turn toward the arc track 2. At the same time, under the rotation of the rotating plate 54, the guide wheel 53 also gradually transitions from the inner wall of the linear track 1 to the inner wall of the arc track 2, further guiding the line component 5 into the arc track 2. In this process, the swinging blades 62 and the annular wheel 63 can accurately limit the position of the convex cone plate 64 through the cooperation of the lock column 621 and the notch 631, ensuring that it accurately guides the line component 5 and avoids deviation, thereby realizing precise track change from the linear track 1 to the arc track 2.

[0056] When it is necessary to change tracks from the curved track 2 back to the linear track 1, the process direction is reversed, the traction device relaxes the traction rope 57, the torsion spring 563 recovers its deformation, drives the rotating plate 54 to rotate in the opposite direction, and makes the guide wheel 53 turn towards the linear track 1. At the same time, after the sensor 66 detects the signal, the gear A61 and the gear B67 drive in the opposite direction, and the cam 68 drives the distribution plate 69 to swing toward the linear track 1, guiding the line component 5 to smoothly transition from the curved track 2 to the linear track 1.
