Description

Technical Field

[0001] The invention relates to the technical field of suspension conveying, and in particular to an intelligent suspension conveying system for food packaging. Background Art

[0002] A suspended conveyor is a material conveying equipment that mainly uses a conveying device suspended on an overhead track to transport items. In a food processing plant, it can transport raw materials such as meat and poultry, and it can also transport packaged food. This suspended conveying method is cleaner than the conveyor belt conveying method. Food can contact the conveying equipment in a small area to avoid contamination of the food by pollutants remaining on the conveying equipment, thereby ensuring the quality and safety of food processing.

[0003] In the process of hanging and conveying food packaging, most of the existing conveying devices are irregular tracks to adapt to different conveying scenarios. In order to facilitate hanging and conveying, there will be turns. The turn is a key part of the conveying device to change the direction of the conveying route. During the hanging and conveying of food packaging, due to inertia problems, the food packaging bags will swing toward the outer circle of the bend, which will cause the food packaging bags to shake continuously, easily affecting the stability of the food packaging bag conveying, and excessive shaking will cause the food packaging bags to be unhooked from the hook, causing the food packaging bags to fall, causing damage to the food packaging bags and food.

Fixed blocks are rotatably connected inside the two hinges. Torsion springs are fixedly connected on both sides of the fixed blocks. The torsion spring is fixedly connected to the hinge at one end away from the connection with the fixed block. The fixed block is fixedly connected to a protective plate at one end away from the connection with the hinge. The material of the protective plate is lightweight plastic.

[0006] Furthermore, the guide rail is composed of vertical bar rings and horizontal bar rings, and its cross-section is an inverted T-shape, each set of pulleys is symmetrically arranged with respect to the vertical bar rings of the guide rail, and the connecting frame is composed of two triangular vertical plates and a C-shaped plate.

[0007] Furthermore, a stabilizing assembly is provided on the connecting frame, and the stabilizing assembly includes two abutment frames fixedly connected to both sides of the connecting frame, and two abutment wheels are rotatably connected to both ends of the tops of the two abutment frames.

[0008] Furthermore, the two contact wheels on each contact frame are located on both sides of the corresponding pulley, and the contact wheels both contact with the surface of the vertical bar ring of the guide rail.

[0009] Furthermore, a locking assembly is provided at the bottom of the connecting frame, and the locking assembly includes a fixing frame fixedly connected to the bottom of the connecting frame, four sliding grooves are opened on the fixing frame, two double-headed servo motors are fixedly connected to the middle part of the fixing frame, threaded rods are fixedly connected to the two output ends of the double-headed servo motors, two sliders are slidably connected between the two sliding grooves, and the bottoms of the two sliders are fixedly connected with resistance blocks, the inner ring surface of the hook is provided with a contact switch 1, and the outer surface of the protective plate is fixedly connected with a contact switch 2.

[0010] Furthermore, threaded holes are provided at both ends of the two sliders, and the threaded holes of the two sliders are threadably matched with the threaded rods.

[0011] Furthermore, the hook is provided with an anti-drop component for preventing the food packaging bag from falling, the anti-drop component includes a boss fixedly connected to the hook, movable grooves are provided on both sides of the boss, spring 1 is fixedly connected to the inside of the movable groove, the end of the spring 1 away from the movable groove is fixedly connected to a sliding rod, the end of the sliding rod away from the spring 1 is fixedly connected to a connecting plate, the side of the connecting plate away from the boss is fixedly connected to a fixing tube, the end of the connecting plate away from the boss is fixedly connected to a spring 2, the end of the spring 2 away from the connecting plate is fixedly connected to a resistance rod, the end of the resistance rod close to the spring 2 slides inside the fixing tube, and the outer side of the sliding rod is fixedly connected to a locking block.

[0013] As described above, the beneficial effects of the intelligent suspension conveying system for food packaging in the present invention are as follows: The two protective plates are used to resist the two sides of the food packaging bag, which can reduce the shaking amplitude of the food packaging bag during transportation and prevent the food packaging bag from swinging excessively due to the bending of the conveying track during transportation. At the same time, the protective plates are pushed and unfolded by the food packaging bag when it is hung on the hook, so that it can adapt to different food packaging bags. The slider allows the abutment block to only abut against the outer side of the protective plate, thereby limiting the protective plate. The protection plate can effectively limit the food packaging bag from swinging during transportation, thereby ensuring the stable transportation of the food packaging bag and preventing the food packaging bag from being damaged by collision during transportation. The locking block blocks the hook opening of the hook, which can prevent the packaging bag from falling off the hook. Compared with the existing anti-drop device on the hook, the locking block blocks the hook opening of the hook without occupying the size of the hook opening, and thus will not affect the hanging of the food packaging bag into the hook. When the spring drives the slide bar to move, the locking block will no longer block the hook opening, thereby achieving a quick unblocking effect. Compared with the existing anti-drop device on the hook, it can reduce unnecessary pressing operations, and the anti-drop device will not affect the taking of the food packaging bag. By having the resistance wheel always resist the surface of the vertical bar ring of the guide rail, the misalignment of the pulley can be calibrated to prevent the pulley from being misaligned, thereby preventing the pulley from being worn due to the swinging of the food packaging bag, further reducing the deformation of the pulley, and ensuring the smoothness of the food packaging bag transportation. In addition, it can also reduce the damage caused by wear, thereby reducing the maintenance cost caused by wear, and further reducing the transportation cost of the food packaging bag.

The outer sides of the two pulleys 36 of each group are rotatably connected with a connecting frame 37, and the connecting frame 37 is composed of two triangular vertical plates and a C-shaped plate. The bottom of the C-shaped plate of the connecting frame 37 is rotatably connected with a hook 38, and the inner sides of the inner sides of the C-shaped plates of the multiple connecting frames 37 are commonly fixedly connected with a chain 39, and the chain 39 is transmission-connected with the shift block 33; It should be noted that the guide rail 35 is a simple example of a suspension conveying rail, and the actual suspension conveying rail may be designed in different styles depending on the site.

[0018] Both sides of the connecting frame 37 are provided with protection components for protecting the suspended packages, and the protection components include hinges 41 symmetrically fixedly connected to the two sides of the bottom of the connecting frame 37, and the interiors of the two hinges 41 are rotatably connected to fixed blocks 43, and both sides of the fixed blocks 43 are fixedly connected to torsion springs 42, and the torsion spring 42 is fixedly connected to the hinge 41 at one end away from the connection with the fixed block 43, and the fixed block 43 is fixedly connected to the protection plate 44 at one end away from the connection with the hinge 41. The material of the protection plate 44 is lightweight plastic, which can easily push the protection plate 44 when the food packaging bag is skewed.

[0019] like Figures 6 to 8 and Fig.10 As shown, a stabilizing component for preventing the pulley 36 from being misplaced is provided on the connecting frame 37, and the stabilizing component includes two abutment frames 51 fixedly connected to both sides of the connecting frame 37, and two abutment wheels 52 are rotatably connected to both ends of the tops of the two abutment frames 51, and the two abutment wheels 52 on each abutment frame 51 are located on both sides of the corresponding pulley 36, and the abutment wheels 52 abut against the surface of the vertical bar ring of the guide rail 35.

[0020] like Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, a locking assembly for smoothly conveying food packaging bags is provided at the bottom of the connecting frame 37, and the locking assembly includes a fixing frame 61 fixedly connected to the bottom of the connecting frame 37, four slide grooves 62 are provided on the fixing frame 61, and two double-headed servo motors 63 are fixedly connected to the middle of the fixing frame 61, and threaded rods 64 are fixedly connected to the two output ends of the double-headed servo motors 63, and two sliders 65 symmetrical to the connecting frame 37 are slidably connected between the two slide grooves 62, and threaded holes corresponding to the positions of the threaded rods 64 are provided at both ends of the two sliders 65, and the threaded holes of the two sliders 65 are threadedly matched with the threaded rods 64, and the bottoms of the two sliders 65 are fixedly connected with resistance blocks 66, and the inner ring surface of the hook 38 is provided with a contact switch 1 67, and the outer surface of the protective plate 44 is fixedly connected with a contact switch 2 68.

[0021] like Figure 6 , Figure 7 and Fig.10 As shown, the hook 38 is provided with an anti-drop component for preventing the food packaging bag from falling, and the anti-drop component includes a boss 71 fixedly connected to the hook 38, and movable grooves 72 are provided on both sides of the boss 71. The interior of the movable groove 72 is fixedly connected with a spring 73, and the end of the spring 73 away from the movable groove 72 is fixedly connected to a slide bar 74, and the slide bar 74 slides in the movable groove 72. The end of the slide bar 74 away from the spring 73 is fixedly connected to a connecting plate 75, and the side of the connecting plate 75 away from the boss 71 is fixedly connected A fixing tube 76 is connected, and a spring 2 77 is fixedly connected to one end of the connecting plate 75 away from the boss 71. The spring 2 77 is located inside the fixing tube 76. The elastic force of the spring 2 77 is greater than the elastic force of the spring 1 73. A resistance rod 78 is fixedly connected to one end of the spring 2 77 away from the connecting plate 75. The end of the resistance rod 78 close to the spring 2 77 slides inside the fixing tube 76. A locking block 79 is fixedly connected to the outer side of the sliding rod 74. An opening 710 is provided on one of the protective plates 44 for the resistance rod 78 and the fixing tube 76 to move.

[0022] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: The protective plate 44 is in a naturally drooping state, and the torsion spring 42 is not twisted and tightened by the fixed block 43. The two sliders 65 are on the side of the slide slot 62 away from the connecting frame 37. The two resistance blocks 66 are located at symmetrical positions on the fixed frame 61 with the connecting frame 37 as the center. The resistance blocks 66 do not resist the resistance rod 78, and thus the spring 2 77 is not compressed by the resistance rod 78. The slide rod 74 does not compress the spring 1 73. At this time, the slide rod 74 prevents the locking block 79 from blocking the hook mouth of the hook 38.

[0023] The working status is: The staff starts the driving motor 31, and the output shaft of the driving motor 31 drives the driving disk 32 to rotate. The driving disk 32 drives the chain 39 to transmit through the shift block 33. During the transmission process, the chain 39 will drive multiple connecting frames 37 to move synchronously. The connecting frame 37 will move along the shape of the guide rail 35 as the trajectory due to the rolling of the pulley 36 on the horizontal groove of the guide rail 35. The connecting frame 37 drives the hook 38 to move synchronously. At this time, the staff can hang the food packaging bag that needs to be suspended and transported on the hook 38, and the movement of the hook 38 drives the food packaging bag to move synchronously, thereby realizing the hanging and transportation of the food packaging bag.

[0024] The protective component protects the food packaging bag: When the food packaging bag is hung on the hook 38, the food packaging bag will touch the protective plate 44, and when the food packaging bag is completely hung on the hook 38, the food packaging bag will push the protective plate 44 to drive the fixed block 43 to rotate upward with the hinge 41 as the axis. The fixed block 43 will twist the torsion spring 42 during the rotation, so that the torsion spring 42 gradually deforms and tightens. Under the elastic reset action of the torsion spring 42 after tightening, the fixed block 43 drives the protective plate 44 to always contact the food packaging bag. The two protective plates 44 contact the two sides of the food packaging bag, which can reduce the shaking amplitude of the food packaging bag during transportation, and avoid excessive swinging of the food packaging bag due to the bending of the conveying track during transportation. At the same time, the protective plate 44 is pushed and unfolded by the food packaging bag when it is hung on the hook 38, so as to adapt to food packaging bags of different sizes.

[0025] The stabilizing assembly stabilizes the rolling of the pulley 36 on the guide rail 35: Because the food packaging bag swings at the bent position of the guide rail 35, the food packaging bag only applies a vertical downward pulling force to the connecting frame 37 through the hook 38 during normal movement. The swinging of the food packaging bag will cause the downward pulling force of the connecting frame 37 through the hook 38 to become skew, which can easily cause the pulley 36 to be misaligned when rolling on the guide rail 35, resulting in friction between the side of the pulley 36 and the vertical bar ring of the guide rail 35. If the pulley 36 is excessively worn, it will cause the pulley 36 to deform, which not only affects the smoothness of the pulley 36 in conveying the food packaging bag, but also affects the service life of the pulley 36, thereby increasing the cost of conveying the food packaging bag.

[0026] By having the resistance wheel 52 always resist the surface of the vertical bar ring of the guide rail 35, the misalignment of the pulley 36 can be calibrated to prevent the pulley 36 from being misaligned, thereby preventing the pulley 36 from being worn due to the swinging of the food packaging bag, and further reducing the deformation of the pulley 36, thereby ensuring the smoothness of the food packaging bag transportation. In addition, it can also reduce the damage caused by wear, thereby reducing the maintenance cost caused by wear, and further reducing the transportation cost of the food packaging bag.

[0027] The anti-drop assembly restricts the packaging bag to the hook 38: In the process of the food packaging bag being hung on the hook 38, the handle of the food packaging bag will be placed on the inner ring surface of the hook 38, and then the food packaging bag will press the contact switch 1 67 by its own weight, and the contact switch 1 67 will control the double-headed servo motor 63 to start, and the output shaft of the double-headed servo motor 63 will drive the threaded rod 64 thereon to rotate, and when the threaded rod 64 rotates, it drives the slider 65 in the slide groove 62 to move toward the side close to the connecting frame 37 through the threaded hole, and the slider 65 drives the resistance block 66 to move toward the side close to the connecting frame 37, and the resistance block 66 will push the resistance rod 78 to move during the movement, and at this time, the resistance rod 78 will push the connecting plate 75 to move through the spring 2 77, and the connecting plate 75 will push the slide rod 74 to move inside the movable groove 72 and compress the spring 1 The movement of the slide bar 74 will drive the locking block 79 to move synchronously. When the locking block 79 blocks the hook opening of the hook 38, the connecting plate 75 also moves synchronously to the interference position with the boss 71. Because the connecting plate 75 has already interfered with the connecting plate 75 and cannot move, the interference block 66 will continue to push the interference rod 78 under the pushing action of the continued movement of the interference block 66. The interference rod 78 will move inside the fixed tube 76 toward the side close to the connecting plate 75 and compress the spring 2 77. The locking block 79 blocks the hook opening of the hook 38, which can prevent the packaging bag from falling off the hook 38. At the same time, compared with the existing anti-drop device on the hook, the method of blocking the hook opening of the hook 38 by the locking block 79 will not occupy the size of the hook opening, and will not affect the hanging of the food packaging bag into the inside of the hook 38.

[0028] In addition, if a food packaging bag is taken, the handle of the food packaging bag will no longer contact the contact switch 1 67 during the process of taking the food packaging bag, and the contact switch 1 67 will control the output shaft of the double-headed servo motor 63 to rotate in the opposite direction, and the output shaft of the double-headed servo motor 63 will drive the threaded rod 64 to rotate in the opposite direction, and the threaded rod 64 will drive the slider 65 to move inside the double-headed servo motor 63 to the side away from the connecting frame 37, and the slider 65 will drive the contact block 66 to move synchronously to the side away from the connecting frame 37. At this time, under the elastic reset action of the spring 2 77, the spring 2 77 will make the contact block 66 move in the opposite direction. The lever 78 is always in conflict with the conflicting block 66. When the conflicting rod 78 moves the fixing tube 76 away from one end of the connecting plate 75, the sliding rod 74 drives the conflicting rod 78 on the spring 2 77 to always conflict with the conflicting block 66 through the connecting plate 75 under the elastic restoring action of the spring 1 73. In the process of the sliding rod 74 being driven by the spring 1 73 to move, the locking block 79 will no longer block the hook mouth of the hook 38, thereby achieving the effect of quickly releasing the blocking. Compared with the existing anti-dropping device on the hook, it can reduce unnecessary pressing operations, and at the same time, the anti-dropping device will not affect the taking of the food packaging bag.

[0029] The locking assembly ensures stability when transporting the food packaging bag through the protective plate 44: As the above-mentioned resistance block 66 continues to move, it will resist the protective plate 44. Under the resistance of the resistance block 66 on the protective plate 44, the protective plate 44 cannot be expanded outward. At the same time, after the resistance block 66 resists the contact switch 2 68 on the protective plate 44, the contact switch 2 68 can control the double-headed servo motor 63 to stop driving the slider 65 to move through its output shaft. The slider 65 makes the resistance block 66 only resist the outer side of the protective plate 44, thereby restricting the protective plate 44. In this way, the protection plate 44 is restricted to the food packaging bag, which effectively avoids the problem of swinging of the food packaging bag during transportation, thereby ensuring the stable transportation of the food packaging bag.

[0030] It should be noted that the protective plate 44 has different unfolding positions after being supported by food packaging bags of different sizes. Through the extended resistance rod 78, the resistance block 66 can push the resistance rod 78 when the protective plate 44 is unfolded at different angles, thereby avoiding the problem that the protective plate 44 is unfolded at too large an angle and cannot push the resistance rod 78. If the unfolding angle of the protective plate 44 is too small, the resistance block 66 pushes the resistance rod 78, causing the resistance rod 78 to compress the spring 2 77 and slide into the fixed tube 76. At this time, the resistance block 66 can also resist the protective plate 44, thereby limiting the protective plate 44.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
