Description

Technical Field

[0001] This invention relates to the field of material conveying equipment technology, specifically an automatic conveying and turning device for multi-station cured meat hanging racks. Background Technology

[0002] As a traditional cured meat product with distinctive regional characteristics in my country, the preparation process of cured meat mainly includes key processing steps such as curing, air drying, smoking, and aging. In the overall processing of cured meat, the workpiece must be placed in a hanging manner throughout the process, and it is necessary to regularly turn it over and adjust its position to ensure that the overall degree of air drying, smoking color, and flavor absorption of the cured meat remain uniform. This operation method is an important process condition to ensure the quality of the finished cured meat and improve the consistency of product processing.

[0003] Generally, in the automated processing and conveying of cured meat, the cured meat is usually suspended on a fixed rack. A monorail conveyor mechanism carries the rack and the cured meat workpiece to each designated processing station to complete the corresponding processing operations.

[0004] However, existing cured meat hanging rack conveying devices have some problems. For example, while the suspended rack can be easily moved by sliding on a single rail, it is prone to swaying and positional deviation when moving on the rail, which affects the stability of the cured meat rack movement. Furthermore, it is inconvenient to lock and fix the cured meat rack after angle adjustment during the cured meat turning process, lacking a self-locking function. This makes the rack prone to secondary swinging during processing, causing the cured meat hanging position to shift and affecting the quality of the finished cured meat. Therefore, to address the above problems, a multi-station automatic conveying and turning device for cured meat racks is proposed. Summary of the Invention

[0039] 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.

[0040] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail. Example 1

[0041] This application discloses an automatic conveying and flipping device for multi-station cured meat hanging racks. (Refer to...) Figures 1-9 An automatic conveying and turning device for multi-station cured meat racks includes: a frame 1 and a suspension frame 23. An electrical control box is fixedly installed on the frame 1, and a PLC controller is installed in the electrical control box. The electrical control box is electrically connected to the electrical components in the device. The electrical components in the device are connected to an external power source through wires to provide power to the electrical components in the device. This is prior art and will not be described in detail here.

[0042] A support frame 2 is fixedly installed above the frame 1. The support frame 2 is equipped with a marinating station 3, an air-drying station 4, a smoking station 5, and a cooking station 6 in sequence. It is used to continuously transport the cured meat rack to meet the processing requirements of the cured meat. The corresponding station is equipped with a positioning sensor and a station trigger switch. When the walking base 7 moves to the corresponding station, the corresponding positioning sensor triggers a signal, thereby controlling the variable frequency motor to stop and realize the stopping at the corresponding station, so as to realize the processing of cured meat at each station.

[0043] The annular suspension conveyor mechanism is mounted on the support frame 2. The annular suspension conveyor mechanism includes an annular suspension conveyor rail 22 and a drive assembly. The annular suspension conveyor rail 22 is configured as a closed loop, and the drive assembly is located inside the area enclosed by the annular suspension conveyor rail 22.

[0044] The suspended travel mechanism includes multiple sets of independent bracket assemblies, each of which is slidably connected to the annular suspended conveyor rail 22.

[0045] The suspension frame 23 includes a walking base 7, a connecting arm 8, and a bearing seat 9. The walking base 7, the connecting arm 8, and the bearing seat 9 are integrally formed to achieve the integrity and stability of the suspension frame 23 structure. The connecting arm 8 is fixedly installed on the walking base 7, and the bearing seat 9 is fixedly installed at the lower end of the connecting arm 8. The bearing seat 9 has a cavity 10, so that the self-locking flipping drive component is installed in the cavity 10. Compared with the existing device, there is no need for an external independent device to transport and flip the multi-layer suspension frame. It realizes integrated transportation and self-locking flipping of the multi-layer suspension frame, ensuring the effect of transporting the cured meat rack.

[0046] A self-locking tilting drive assembly is mounted on the cavity 10. The assembly includes a drive motor 11, a reducer 12, a rotating base 13, an electric push rod 14, a positioning post 15, and self-locking holes 16. The output end of the drive motor 11 is connected to the reducer 12 via a coupling. The rotating base 13 is located below the bearing seat 9, and the output end of the reducer 12 is connected to the rotating base 13. The electric push rod 14 is located in the cavity 10, and the output end of the electric push rod 14 passes through the cavity 10 and is connected to the positioning post 15. Multiple self-locking holes 16 are evenly distributed on the rotating base 13 in a circular array. An angle sensor 17 is installed below the rotating seat 13. The angle sensor 17 monitors the rotation angle of the rotating seat 13 in real time and sends an electrical signal to the electrical control box. The electrical signal is processed to control the operation of the corresponding drive motor 11 to rotate the rotating seat 13, thereby rotating the cured meat hanging on the multi-layer hanging rack. When the rotating seat 13 rotates to a suitable angle, the electric push rod 14 is controlled to push the positioning post 15 down, so that the lower end of the positioning post 15 is locked into the corresponding self-locking hole 16, thereby ensuring the positioning and self-locking of the rotating seat 13.

[0047] The multi-layer hanging rack is used to hang cured meat. The multi-layer hanging rack is detachably installed below the turntable 13. The multi-layer hanging rack is made of high-quality steel and can be used to hang cured meat.

[0048] Reference Figure 1The drive assembly includes a drive gear 18, a driven gear 19, a variable frequency motor 20, and a closed-loop transmission chain 21. The drive gear 18 and the driven gear 19 are rotatably mounted on the upper sides of the support frame 2, and the drive gear 18, the driven gear 19 and the closed-loop transmission chain 21 mesh with each other. The variable frequency motor 20 is located below the support frame 2. The output end of the variable frequency motor 20 is connected to the drive gear 18 through a coupling. Through this structure, the closed-loop transmission chain 21 is driven.

[0049] Reference Figure 1 and Figure 9 The annular suspension conveyor rail 22 and the closed-loop transmission chain 21 are structurally set in proportion to the side profile of the support frame 2, which ensures that the traveling base 7 moves smoothly on the annular suspension conveyor rail 22 and that the limiting bracket 29 can move smoothly at the edge of the support frame 2.

[0050] Reference Figure 2 and Figure 5 The bracket assembly includes a suspension frame 23, a connector 24, a mounting base 25, and an anti-sway limit wheel 26;

[0051] A connector 24 is fixedly installed on the walking base 7. The connector 24 is fixedly connected to the closed-loop transmission chain 21. A mounting base 25 is installed below the walking base 7, located on both sides of the annular suspension conveyor rail 22. Multiple sets of anti-sway limit wheels 26 are evenly arranged on the mounting base 25. The anti-sway limit wheels 26 are in contact with the side of the annular suspension conveyor rail 22. Through this structure, the stability of the walking base 7 in moving on the annular suspension conveyor rail 22 is ensured, and the suspension frame 23 is prevented from shaking and shifting position, thereby affecting the stability of the cured meat hanging rack.

[0052] Reference Figure 1 and Figure 6 An annular rail groove 27 is provided above the annular suspension conveyor rail 22, and a slide 28 is fixedly provided below the traveling base 7. The slide 28 is slidably connected to the annular rail groove 27 to improve the stability of the traveling base 7 moving on the annular suspension conveyor rail 22.

[0053] Reference Figure 1 and Figure 7 A limiting bracket 29 is fixedly installed on the connecting arm 8. The limiting bracket 29 is arranged in a U-shape and is slidably connected to the edge of the support frame 2. A rotating roller 30 is rotatably installed on the inner side of the limiting bracket 29. The rotating roller 30 can fit and rotate with the side of the support frame 2. By moving the limiting bracket 29 at the edge of the support frame 2, the swaying and positional displacement of the suspension frame 23 are prevented, thereby affecting the stability of the movement of the cured meat hanging rack.

[0054] Reference Figure 5The bottom of the bearing seat 9 is provided with an annular groove 31, and multiple sliding columns 32 are fixedly provided on the rotating seat 13. The upper end of the sliding column 32 is slidably connected to the annular groove 31. This structure improves the stability of the rotating seat 13 in angle adjustment. Example 2

[0055] Reference Figure 2 and Figure 5 A photoelectric positioning receiver 33 is provided on one side of the self-locking hole 16, and a photoelectric positioning sensor 34 is provided on the positioning post 15. The photoelectric positioning receiver 33 and the photoelectric positioning sensor 34 are electrically connected. The rotation angle of the turntable can be preset. Through the structure of the angle sensor 17, the rotation angle of the turntable 13 is monitored in real time, and an electrical signal is sent to the electrical control box. By processing the electrical signal, the operation of the corresponding drive motor 11 is controlled to rotate the turntable 13, thereby angling the cured meat hanging on the multi-layer hanging rack. The rotation process involves rotating the turntable 13 to a suitable angle. When the photoelectric positioning sensor 34 and the photoelectric positioning receiver 33 on the corresponding self-locking hole 16 side are detected and identified, the electric push rod 14 is controlled to move, thereby pushing the positioning column 15 down and locking the lower end of the positioning column 15 into the corresponding self-locking hole 16. This ensures the self-locking of the turntable 13 and the self-locking of the cured meat hanging rack, preventing secondary swinging of the multi-layer hanging rack during processing, which could cause the cured meat hanging position to shift and affect the quality of the finished cured meat.

[0056] Reference Figure 3 and Figure 4 The multi-layer suspension frame includes a top plate 35, support rods 36, sliding sleeves 37, suspension crossbars 38, and cured meat hooks 39. The top plate 35 is detachably mounted below the turntable 13 by fasteners. Multiple sliding sleeves 37 are slidably connected to the outer side of the support rods 36. Multiple suspension crossbars 38 are evenly arranged on the sliding sleeves 37. Multiple cured meat hooks 39 are evenly arranged on the suspension crossbars 38. Insertion holes 40 are opened on the suspension crossbars 38. Multiple limiting supports 41 are fixedly installed below the top plate 35. Insertion holes 40 on the same vertical plane are slidably connected to the corresponding limiting supports 41. Through the structure of the multi-layer suspension frame, the spacing between the suspension crossbars 38 can be adjusted. Furthermore, the suspension crossbars 38 slide on the insertion holes 40 on the corresponding limiting supports 41 to ensure the stability of the movement adjustment of the suspension crossbars 38.

[0057] Reference Figure 3 and Figure 4The support rod 36 has multiple adjustment holes 42 evenly distributed in the vertical direction, and the sliding sleeve 37 has a positioning hole 43. The adjusted positioning hole 43 is connected to the adjustment hole 42 by fasteners. With this structure, the position of the sliding sleeve 37 can be flexibly adjusted, so that the corresponding multiple suspension crossbars 38 on the sliding sleeve 37 can be moved, thereby meeting the needs of hanging cured meat of different sizes.

[0058] Working principle: By arranging four major processing stations in sequence along the material conveying direction on the support frame 2, namely the marinating station 3, the air drying station 4, the smoking station 5, and the cooking station 6, a continuous processing line for cured meat is formed.

[0059] Through the structural design of the annular suspension conveyor mechanism, the annular suspension conveyor rail 22 is a closed-loop structure. The drive component is integrated inside the enclosed area of ​​the annular suspension conveyor rail 22. During operation, the variable frequency motor 20 receives the control signal transmitted from the control box and drives the drive gear plate 18 to rotate through the coupling. The drive gear plate 18 and the driven gear plate 19 mesh with the closed-loop transmission chain 21 to realize the operation of the closed-loop transmission chain 21.

[0060] Among them, the annular suspension conveyor rail 22, the closed-loop transmission chain 21 and the side contour of the support frame 2 are set in proportion to ensure that each hanger component is transported smoothly along the annular suspension conveyor rail 22.

[0061] The suspension walking mechanism ensures smooth movement of the hanger components throughout the entire process. Multiple independent hanger components can transport their corresponding multi-layer suspension frames. The walking base 7, connecting arm 8, and bearing seat 9 are integrally formed to constitute the suspension frame body 23, resulting in high overall structural strength and stability. The walking base 7 is connected to the closed-loop transmission chain 21 via the connector 24 and can move synchronously along the annular suspension conveyor rail 22 following the closed-loop transmission chain 21. A slide 28 is provided below the walking base 7, which slides and fits into the annular groove 27 at the top of the annular suspension conveyor rail 22, realizing the sliding and limiting of the walking base 7. In addition, multiple anti-sway limiting wheels 26 are arranged on the mounting seats 25 on both sides of the walking base 7. The anti-sway limiting wheels 26 slide against the side of the annular suspension conveyor rail 22 to prevent deviation and limit the movement of the walking base 7.

[0062] Furthermore, a U-shaped limiting bracket 29 is fixedly installed on the connecting arm 8. The limiting bracket 29 slides with the edge of the support frame 2, and a rotating roller 30 is rotatably installed on its inner side. The rotating roller 30 rolls against the side of the support frame 2 to avoid swaying and deviation during the movement of the suspended frame 23. When the walking base 7 moves the workpiece to any station, the positioning sensor of the corresponding station detects the workpiece signal and triggers the station trigger switch. After receiving the signal, the PLC controller controls the variable frequency motor 20 to stop, so that the workpiece can stop at the pickling station 3, the air drying station 4, the smoking station 5, and the cooking station 6.

[0063] A self-locking flipping drive assembly is integrated within the cavity 10 of the support seat 9, replacing the traditional external flipping device. This achieves integrated conveying and flipping operation, allowing for multi-angle processing of the hung cured meat. When stopped at a designated workstation, the drive motor 11 drives the reducer 12 via a coupling. The output of the reducer 12 drives the rotating seat 13 to rotate. Multiple sets of sliding columns 32 fixed at the bottom of the rotating seat 13 slide and engage within the annular groove 31 at the bottom of the support seat 9, ensuring smooth and seamless angle adjustment of the rotating seat 13. During the flipping process of the multi-layer suspension frame, the angle sensor 17 below the rotating seat 13 collects rotation angle data in real time and transmits the electrical signal in real time. The data is sent to the electrical control box for analysis and processing. When the rotary table 13 rotates to the preset processing angle, the photoelectric positioning receiver 33 on the side of the self-locking hole 16 and the photoelectric positioning sensor 34 on the positioning column 15 complete the sensing and identification. The electrical control box immediately controls the drive motor 11 to stop. At the same time, the electric push rod 14 inside the cavity 10 runs. The electric push rod 14 drives the output end to push the positioning column 15 downward, so that the lower end of the positioning column 15 is accurately locked into the corresponding self-locking hole 16 on the rotary table 13, realizing the mechanical self-locking of the rotary table 13. This avoids the problem of secondary swinging and displacement of the rotary table 13 and the workpiece suspended below during the processing, and ensures the angle of the cured meat processing position.

[0064] A multi-layer hanging rack can be detachably installed below the rotating base 13. The multi-layer hanging rack can be used to hang cured meat. The top plate 35 of the rack is fixed to the bottom of the rotating base 13 with fasteners, which facilitates the disassembly and assembly of the multi-layer hanging rack later. When hanging cured meat of different sizes, the corresponding multiple hanging crossbars 38 on the sliding sleeve 37 can be moved to adjust the spacing of the hanging crossbars 38. The staff can adjust the vertical spacing of the hanging crossbars 38 by sliding the sliding sleeve 37 up and down according to the size of the cured meat. After adjustment, the fasteners are fixed and locked through the positioning hole 43 and the corresponding adjustment hole 42. At the same time, the hanging crossbars 38 have insertion holes 40. The limiting support rod 41 is fixed below the top plate 35 of the rack. The limiting support rod 41 slides with the insertion hole 40 to ensure the stability of the structure after the hanging crossbars 38 are adjusted and the meat is hung, and to avoid lateral displacement.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
