Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly relates to a double-layer conveying device for components. Background Art

[0002] Components are various parts that make up industrial products, including the collective name of parts and components. For example, in the mechanical field, components include bearings, gears, hydraulic components, etc.; in the automotive field, components cover engines, suspension systems, braking systems, etc.

[0003] The double-layer conveying device for components is an efficient material conveying equipment, usually composed of multiple-layer conveying structures, driving devices, supporting frames, and supporting control systems. Its main function is to achieve efficient material transfer and conveying within a limited space.

[0004] For existing component conveying devices, it is difficult to sort and convey different components, resulting in the need for manual sorting in the later stage, which reduces the production speed. At the same time, it causes uneven loads on the conveyor belt and the chain, affecting the overall conveying efficiency. When facing heavier components, the conveyor belt cannot adaptively adjust the tension, exacerbating device wear and causing slipping and deviation phenomena, resulting in unstable conveying speed. In addition, continuous conveying operations will increase the friction of the rotating shaft, and components such as the motor belt generate a large amount of heat energy, significantly reducing the service life and operating efficiency of the device. Therefore, this application provides a double-layer conveying device for components to meet the requirements. Summary of the Invention

[0028] Such as Figures 1 to 12As shown in the figure, an embodiment of the present invention provides a double-layer conveyor device for parts, including a double-layer lifting bracket 1. One end of the double-layer lifting bracket 1 is installed with a glass bracket 2. One end of the glass bracket 2 is installed with an auxiliary bracket 3. The top of the auxiliary bracket 3 is installed with a conveyor belt 5. Two groups of roller brackets 4 are installed at the end of the double-layer lifting bracket 1. The top of the double-layer lifting bracket 1 is installed with a first conveyor belt 17. The bottom of the double-layer lifting bracket 1 is installed with a second conveyor belt 18. A driving chain 15 is slidably installed on the inner wall of the glass bracket 2. One end of the driving chain 15 is installed with a lifting and conveying platform 9. The bottom of the roller bracket 4 is installed with a control center 10. One side of the double-layer lifting bracket 1 is installed with a motor 11.

One end of the belt protection case 12 is installed with an air box 13. One end of the lifting and conveying platform 9 is installed with an auxiliary roller 16; A positioning and weighing assembly 6 is arranged above the auxiliary bracket 3. The positioning and weighing assembly 6 is used for weighing different types of parts; A tension adjusting assembly 7 is rotatably connected to the inner wall of the second conveyor belt 18. The tension adjusting assembly 7 is used for adjusting the tension degree of the second conveyor belt 18; One end of the tension adjusting assembly 7 is sleeved with a heat dissipation and lubrication assembly 8. The heat dissipation and lubrication assembly 8 is used for lubricating and cooling the machine after it stops; One end of the positioning and weighing assembly 6 is installed with a tension adjusting assembly 7. One end of the tension adjusting assembly 7 is installed with a heat dissipation and lubrication assembly 8.

[0029] As an implementation manner in this embodiment, as Figures 3 to 6As shown in the figure, the alignment and weighing assembly 6 includes a plug board 61, which is plugged and installed on the top of the idler bracket 4. There are multiple groups of plug boards 61, which are respectively arranged above the auxiliary bracket 3. A rotating shaft 62 is rotatably installed on one side of the plug board 61. An alignment plate 63 is installed on the surface of the rotating shaft 62. A first spring 64 is installed on one side of the alignment plate 63, and the other end of the first spring 64 is installed on the surface of the plug board 61. An installation fixing plate 65 is installed on the inner wall of the idler bracket 4. The installation fixing plate 65 is arranged between the conveyor belts 5. An elastic frame 66 is installed on the surface of the installation fixing plate 65. The elastic frame 66 is arranged around the installation fixing plate 65. A weighing arc plate 67 is installed on the top of the elastic frame 66. The upper surface of the weighing arc plate 67 is in contact with the inner wall of the conveyor belt 5. A weighing sensor 68 is arranged at the bottom of the weighing arc plate 67. When the parts start to be conveyed, the alignment and weighing assembly 6 starts to operate. First, multiple groups of plug boards 61 are plugged into the idler bracket 4 installed on the top of the auxiliary bracket 3. Then, during the conveying process of the parts on the conveyor belt 5, they first come into contact with the alignment plate 63. When the alignment plate 63 comes into contact with the parts, it starts to fold around the rotating shaft 62. At this time, the first spring 64 is compressed by the end of the alignment plate 63 and contracts. At this time, since the flipping angle of the alignment plate 63 is limited, when one side of the alignment plate 63 is folded to the maximum angle, the parts are subjected to the pushing force of the alignment plate 63 and the conveying force of the conveyor belt 5, and start to come into contact with the other end alignment plate 63 during the movement process. Then, through the opening between the two alignment plates 63, they continue to be conveyed in the direction of the glass bracket 2. Subsequently, during the conveying process, the weight of the parts themselves presses down, causing the conveyor belt 5 carrying the parts to come into contact with the weighing arc plate 67. Then the weighing arc plate 67 is pressed and moves downward. At this time, the elastic frame 66 installed at the bottom around the weighing arc plate 67 contracts on the top of the installation fixing plate 65. At the same time, the weighing sensor 68 is pressed to obtain the weight data. Then, according to this weight data, it is transmitted to the control center 10. Then the control center 10 transmits the instruction to the drive chain 15. Then the parts continue to be conveyed on the conveyor belt 5, come into contact with the second group of alignment plates 63 for alignment, and then the parts come into contact with the auxiliary rollers 16 until they are transmitted to the surface of the lifting and conveying platform 9. Subsequently, the drive chain 15 transports the heavier parts to the second conveyor belt 18 at the bottom of the double-layer lifting bracket 1 through the lifting and conveying platform 9 according to the instruction. Subsequently, after the conveyor belt 5 equipped with the alignment and weighing assembly 6 weighs the lighter parts, the lighter parts are directly conveyed to the surface of the lifting and conveying platform 9 through the conveyor belt 5. The drive chain 15 does not need to be driven, so that the lifting and conveying platform 9 and the first conveyor belt 17 at the top of the double-layer lifting bracket 1 are kept horizontal. Then the lighter parts continue to be conveyed from the surface of the lifting and conveying platform 9 to the first conveyor belt 17 at the top of the double-layer lifting bracket 1 for the conveying of the lighter parts, so as to realize the sorting and conveying of the heavier parts and the lighter parts.

[0030] As an implementation mode in this embodiment, as Figures 7 to 10 shown, the tension adjustment assembly 7 includes a cylinder 71. The cylinder 71 is installed at one end of the idler bracket 4. The output end of the cylinder 71 is rotatably connected with a piston sleeve cylinder 72. A rotating shaft 73 is inserted into the piston sleeve cylinder 72. The other end of the rotating shaft 73 is rotatably installed inside the idler bracket 4. A sleeve 74 is sleeved on the surface of the rotating shaft 73. A long strip 75 is installed on the surface of the sleeve 74. Multiple groups of long strips 75 are arranged around the surface of the sleeve 74. One side of the long strip 75 is rotatably connected with a rotating plate 76. Multiple groups of rotating plates 76 are arranged on one side of the long strip 75. One end of the rotating plate 76 is rotatably connected with a connecting strip 77. A belt supporting arc plate 78 is installed at the end of the connecting strip 77. An anti-slip strip is installed on the surface of the belt supporting arc plate 78. Two blocks 79 are installed on the surface of one end of the connecting strip 77. A sliding groove cross 710 is slidably connected to the inner walls of the two blocks 79. A rotating seat 712 is installed on one side of the sliding groove cross 710. The rotating seat 712 is installed inside the idler bracket 4. The end of the rotating shaft 73 is in rolling connection with the rotating seat 712. A roller 711 is installed on one side of the block 79. A partition is arranged at the edge of the roller 711. One end of the belt 14 is sleeved on the surfaces of multiple rollers 711. When the weighing sensor 68 measures the weight of the parts, the tension adjustment assembly 7 starts to operate. First, the cylinder 71 is started. The motor 11 drives the belt 14 to rotate, and adjusts the moving distance of the output end of the cylinder 71 according to the weight of the parts, so that the second conveyor belt 18 reaches the best tension degree. At this time, when the output end of the cylinder 71 moves, it drives the piston sleeve cylinder 72 rotatably connected to the output end of the cylinder 71 to move together. At the same time, the rotating shaft 73 rotates while moving inside the piston sleeve cylinder 72. When the piston sleeve cylinder 72 contacts the sleeve 74, it continues to push towards the direction of the air box 13. When the sleeve 74 is pushed, the multiple long strips 75 installed on the surface of the sleeve 74 move together with the sleeve 74. At the same time, the movement of the long strip 75 drives the rotating plate 76 to move together. When the rotating plate 76 connected to one end of the long strip 75 rotates, the connecting strip 77 connected to the other end of the rotating plate 76 slides around inside the sliding groove cross 710 under the action of the block 79 installed on the surface of the end until the output end of the cylinder 71 stops. When the connecting strip 77 slides in the sliding groove cross 710, the belt supporting arc plate 78 installed at the end of the connecting strip 77 pushes the second conveyor belt 18 on the surface to expand around. At this time, the second conveyor belt 18 becomes tight. At the same time, the sliding of the connecting strip 77 makes the roller 711 move around synchronously. At this time, the belt 14 sleeved on the surface of the roller 711 expands synchronously. The driving of the motor 11 is faster, so that the rotating shaft 73 rotates in the rotating seat 712, ensuring that the second conveyor belt 18 can also operate stably under the condition of heavier parts.

[0031] As an implementation mode in this embodiment, asFigures 8 to 12 As shown in the figure, the heat dissipation and lubrication assembly 8 includes a hoop bracket 81, which is sleeved on the surface of the end of the rotating shaft 73. The hoop bracket 81 is fixedly connected to the surface of the chute cross 710. One end of the hoop bracket 81 is provided with a cylindrical oil storage barrel 82, which is sleeved on the surface of the rotating shaft 73. One end of the cylindrical oil storage barrel 82 is provided with an oil inlet 83, and the bottom of the cylindrical oil storage barrel 82 is provided with an oil outlet 84. The opening end of the oil outlet 84 is provided with an oil guide pipe 85, and the other end of the oil guide pipe 85 is provided with an annular oil pipe rack 86, which is installed at the end of the sleeve 74. A push oil plate 810 is slidably connected inside the cylindrical oil storage barrel 82. One end of the push oil plate 810 is provided with a force-receiving push plate 89. A second spring 88 is installed between the force-receiving push plate 89 and the cylindrical oil storage barrel 82. A plurality of injection nozzles 87 are installed on the inner wall of the annular oil pipe rack 86. When the sleeve 74 moves, the heat dissipation and lubrication assembly 8 starts to operate. At this time, the movement of the sleeve 74 drives the annular oil pipe rack 86 installed at the end of the sleeve 74 to move together. As the annular oil pipe rack 86 moves, it begins to contact the force-receiving push plate 89. When the force-receiving push plate 89 is squeezed by the annular oil pipe rack 86, the push oil plate 810 installed at one end of the force-receiving push plate 89 begins to slide inside the cylindrical oil storage barrel 82. At the same time, the second spring 88 contracts between the cylindrical oil storage barrel 82 and the force-receiving push plate 89. Affected by the fixing effect of the hoop bracket 81 installed at one end of the chute cross 710, the cylindrical oil storage barrel 82 does not move. When the push oil plate 810 moves, the oil liquid flows out through the oil outlet 84 at the bottom of the cylindrical oil storage barrel 82. The flowing oil liquid is transported to the annular oil pipe rack 86 through the oil guide pipe 85, and then is sprayed onto the surface of the rotating shaft 73 through a plurality of injection nozzles 87 installed on the inner wall of the annular oil pipe rack 86. When the output end of the air cylinder 71 keeps pushing, the injection nozzles 87 keep spraying onto the rotating shaft 73. When the conveying device stops operating, the air cylinder 71 resets. At the same time, the force-receiving push plate 89 is reset by the elastic force of the second spring 88. At the same time, when resetting, it pushes the annular oil pipe rack 86 to move together. At this time, the sleeve 74 and the force-receiving push plate 89 move the oil liquid sprayed on the rotating shaft 73 together, playing a role in maintaining the rotating shaft 73. Then, the oil liquid is replenished through the oil inlet 83 for the next conveying of parts.

[0032] The working principle of the technical solution provided by the present invention is as follows: When using this device, first check the stability among the double-layer lifting bracket 1, the glass bracket 2, the auxiliary bracket 3 and the roller bracket 4. Then open the belt protection case 12 to check whether the connection between the motor 11 and the belt 14 is loose. Then clean the air box 13 to ensure the internal cleanliness. Subsequently, start the conveying device. After setting parameters through the control center 10, start the conveying of parts.

[0033] When the parts start to be conveyed, the alignment and weighing assembly 6 starts to operate. First, multiple groups of plug plates 61 are inserted into the roller brackets 4 installed on the top of the auxiliary bracket 3. Then, during the conveyance of the parts on the conveyor belt 5, the parts first come into contact with the alignment plate 63. When the alignment plate 63 contacts the parts, it starts to fold around the rotating shaft 62. At this time, the first spring 64 is compressed by the end of the alignment plate 63 and contracts. Since the flipping angle of the alignment plate 63 is limited, when one side of the alignment plate 63 is folded to the maximum angle, the parts are subjected to the pushing force of the alignment plate 63 and the conveying force of the conveyor belt 5, and start to contact the other end of the alignment plate 63 during the movement. Then, through the opening between the two groups of alignment plates 63, the parts continue to be conveyed in the direction of the glass bracket 2. Subsequently, during the conveying process, the weight of the parts themselves presses down, causing the section of the conveyor belt 5 carrying the parts to come into contact with the weighing arc plate 67. Then, the weighing arc plate 67 is pressed and moves downward. At this time, the elastic frames 66 installed at the bottom around the weighing arc plate 67 contract on the top of the installation fixing plate 65. At the same time, the weighing sensor 68 is pressed to obtain weight data, and then this weight data is transmitted to the control center 10. Then, the control center 10 transmits an instruction to the drive chain 15. Then, the parts continue to be conveyed on the conveyor belt 5, contact and are aligned with the second group of alignment plates 63, and then the parts come into contact with the auxiliary rollers 16 until they are conveyed to the surface of the lifting and conveying platform 9. Subsequently, the drive chain 15 transports the heavier parts to the second conveyor belt 18 at the bottom of the double-layer lifting bracket 1 through the lifting and conveying platform 9 according to the instruction. Then, after the conveyor belt 5 equipped with the alignment and weighing assembly 6 weighs the lighter parts, the lighter parts are directly conveyed to the surface of the lifting and conveying platform 9 through the conveyor belt 5. The drive chain 15 does not need to be driven, so that the lifting and conveying platform 9 is kept horizontal with the first conveyor belt 17 at the top of the double-layer lifting bracket 1. Then, the lighter parts are continuously conveyed from the surface of the lifting and conveying platform 9 to the first conveyor belt 17 at the top of the double-layer lifting bracket 1 for the conveyance of the lighter parts, so as to realize the sorting and conveyance of the heavier parts and the lighter parts.

[0034] When the load cell 68 measures the weight of the component, the tension adjustment assembly 7 starts to operate. First, the air cylinder 71 is activated, and the motor 11 drives the belt 14 to rotate, and adjusts the moving distance of the output end of the air cylinder 71 according to the weight of the component, so that the second conveyor belt 18 reaches the optimal tension level. At this time, when the output end of the air cylinder 71 moves, it drives the piston sleeve cylinder 72 rotatably connected to the output end of the air cylinder 71 to move together. At the same time, the rotating shaft 73 rotates while moving inside the piston sleeve cylinder 72. When the piston sleeve cylinder 72 comes into contact with the sleeve 74, it continues to push towards the direction of the air box 13. When the sleeve 74 is pushed, multiple groups of long strip blocks 75 installed on the surface of the sleeve 74 move together with the sleeve 74. At the same time, the movement of the long strip blocks 75 drives the rotating plate 76 to move together. When the rotating plate 76 connected to one end of the long strip block 75 rotates, the connecting strip 77 connected to the other end of the rotating plate 76 slides around inside the chute cross 710 under the action of the stopper 79 installed on the end surface, until the output end of the air cylinder 71 stops. When the connecting strip 77 slides in the chute cross 710, the belt supporting arc plate 78 installed at the end of the connecting strip 77 pushes the second conveyor belt 18 on the surface to expand around. At this time, the second conveyor belt 18 becomes tight. At the same time, the sliding of the connecting strip 77 also makes the roller 711 move around synchronously. At this time, the belt 14 sleeved on the surface of the roller 711 expands synchronously. The drive of the motor 11 is faster, so that the rotating shaft 73 rotates in the rotating seat 712, ensuring that the second conveyor belt 18 can also operate stably under the condition of heavier components.

[0035] When the sleeve 74 moves, the heat dissipation lubrication assembly 8 starts to operate. At this time, the movement of the sleeve 74 drives the annular oil pipe rack 86 installed at the end of the sleeve 74 to move together. As the annular oil pipe rack 86 moves, it begins to contact the force-receiving push plate 89. When the force-receiving push plate 89 is squeezed by the annular oil pipe rack 86, the oil-pushing plate 810 installed at one end of the force-receiving push plate 89 starts to slide inside the cylindrical oil storage barrel 82. At the same time, the second spring 88 contracts between the cylindrical oil storage barrel 82 and the force-receiving push plate 89. Affected by the fixing effect of the hoop bracket 81 installed at one end of the chute cross 710, the cylindrical oil storage barrel 82 does not move. When the oil-pushing plate 810 moves, the oil liquid flows out through the bottom oil outlet 84 of the cylindrical oil storage barrel 82. The flowing oil liquid is transported to the annular oil pipe rack 86 through the oil guide pipe 85, and then sprayed onto the surface of the rotating shaft 73 through multiple nozzle 87 installed on the inner wall of the annular oil pipe rack 86. When the output end of the cylinder 71 keeps pushing, the nozzle 87 keeps spraying onto the rotating shaft 73. When the conveying device stops operating, the cylinder 71 resets. At the same time, the force-receiving push plate 89 is reset by the elastic force of the second spring 88. At the same time, when resetting, it pushes the annular oil pipe rack 86 to move together. At this time, the sleeve 74 and the force-receiving push plate 89 move the oil liquid sprayed on the rotating shaft 73 together, playing a role in maintaining the rotating shaft 73. Then, the oil liquid is replenished through the oil inlet 83 for the next transportation of parts.
