Description

Technical Field

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

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

[0003] The double-layer parts conveyor is a highly efficient material conveying equipment, usually composed of a multi-layer conveying structure, a drive device, a support frame and a supporting control system. Its main function is to achieve efficient material transfer and transportation within a limited space.

[0004] Existing parts conveying devices make it difficult to sort and convey different parts, resulting in manual sorting in the later stage, which reduces the production speed. At the same time, it causes uneven load on the conveyor belt and chain, affecting the overall conveying efficiency. When facing heavier parts, the conveyor belt cannot adaptively adjust the tension and relaxation, which aggravates the wear of the device and causes slippage and deviation, resulting in unstable conveying speed. In addition, continuous conveying operations will increase the friction of the rotating shaft, and components such as motor belts will generate a large amount of heat energy, which will significantly reduce the service life and operating efficiency of the device. Therefore, this application provides a double-layer parts conveying device to meet the needs. Summary of the Invention

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, the accuracy of sorting and conveying is improved by setting up a calibration weighing component. The calibration plate uses mechanical guidance to ensure that the parts are conveyed in the center, reducing the jamming problem caused by offset, making the weighing detection more stable, and avoiding uneven force. The weighing sensor then identifies the weight difference of the parts in real time and transmits the signal to the lifting platform to provide a quantitative basis for sorting. The conveying channel is dynamically allocated based on weight data to avoid the concentration of parts of different weights on the same conveyor belt, reducing the risk of wear of the conveyor belt's feed wheels. The lifting platform conveys the parts according to weight classification to the conveyor belt of corresponding power, which can reduce the overload and heating of the motor on the conveyor belt. Automated sorting reduces manual intervention, increases the sorting speed, and at the same time reduces the rework loss caused by mixing.

[0019] By setting up a tension adjustment component and linking it with the calibration weighing component, the operating distance of the cylinder and the moving distance of the casing can be adjusted in real time. The conveyor belt tension is adjusted according to the weight of the parts to maintain the optimal friction coefficient when conveying heavy parts, reduce wear between the conveyor belts, and avoid slipping of the conveyor belt due to overweight parts during conveyor belt transportation. In addition, adaptive tensioning can reduce abnormal friction between the pulley and the conveyor belt, extend the service life of the device, reduce motor load fluctuations, avoid slipping and offset, maintain the stability of the conveyor device, reduce maintenance costs, and reduce the risk of sudden belt breakage.

[0020] By setting up a heat dissipation and lubrication component, automatic lubrication of the rotating shaft during shutdown can reduce dry friction between metals, reduce bearing wear rate, ensure effective protection of the rotating shaft in high temperature environments, and increase service life. At the same time, the forced heat dissipation of the fan box can reduce the surface temperature of the motor belt, avoid the risk of breakage caused by rubber aging, and simultaneously reduce the overall temperature of the transmission system, improving operational stability. Regular lubrication and heat dissipation can prevent sudden jamming, extend the continuous operation time of the conveyor, reduce the number of over-temperature protection shutdowns triggered by overheating, and ensure production continuity. The automatic lubrication and heat dissipation system can reduce the frequency of manual maintenance and save maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] As an implementation method in this embodiment, Figures 3 to 6As shown, the calibration weighing assembly 6 includes an insert plate 61, which is plugged and installed on the top of the roller bracket 4. There are multiple groups of insert plates 61, which are respectively arranged above the auxiliary bracket 3. A rotating shaft 62 is rotatably installed on one side of the insert plate 61, and a calibration plate 63 is installed on the surface of the rotating shaft 62. A first spring 64 is installed on one side of the calibration plate 63, and the other end of the first spring 64 is installed on the surface of the insert plate 61. A mounting plate 65 is installed on the inner wall of the roller bracket 4. The mounting plate 65 is arranged between the conveyor belts 5. An elastic frame 66 is installed on the surface of the mounting plate 65. The elastic frame 66 is arranged around the mounting 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 aligned with the conveyor belt 5. The inner walls fit together, and a weighing sensor 68 is provided at the bottom of the weighing arc plate 67. When the parts start to be conveyed, the calibration weighing assembly 6 starts to run. First, multiple sets of plug plates 61 are inserted into the roller bracket 4 installed on the top of the auxiliary bracket 3. Then, during the transportation of the conveyor belt 5, the parts first come into contact with the calibration plate 63. After the calibration plate 63 comes into contact with the parts, it begins to fold around the rotating shaft 62. At this time, the first spring 64 is squeezed and contracted by the end of the calibration plate 63. At this time, since the flipping angle of the calibration plate 63 is limited, when the calibration plate 63 on one side is folded to the maximum angle, the parts are subjected to the top push of the calibration plate 63 and the conveying force of the conveyor belt 5, and begin to come into contact with the calibration plate 63 at the other end during the movement, and then pass through The opening between the two sets of calibration plates 63 continues to be transported in the direction of the glass support 2. Subsequently, during the transportation 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, and then the weighing arc plate 67 is pressed downward. At this time, the elastic frame 66 installed at the bottom of the weighing arc plate 67 shrinks on the top of the mounting plate 65. At the same time, the weighing sensor 68 is pressed down to obtain weight data, which is then transmitted to the control center 10 based on the weight data. The control center 10 then transmits the command to the drive chain 15, and then the parts continue to be transported on the conveyor belt 5, contacting and calibrating with the second set of calibration plates 63, and then the parts come into contact with the auxiliary roller 16 until they are transmitted to the lifting position. The surface of the lowering conveying platform 9 is then driven, and the chain 15 is then driven to transport the heavier parts to the second conveyor belt 18 at the bottom of the double-layer lifting bracket 1 through the lifting conveying platform 9 according to the instructions. Subsequently, the conveyor belt 5 equipped with the calibration weighing component 6 weighs the lighter parts, and the lighter parts are then directly conveyed to the surface of the lifting conveying platform 9 through the conveyor belt 5. The driving chain 15 does not need to be driven, so that the lifting conveying platform 9 and the first conveyor belt 17 at the top of the double-layer lifting bracket 1 are kept horizontal, and then the lighter parts are transported from the surface of the lifting conveying platform 9 to the first conveyor belt 17 at the top of the double-layer lifting bracket 1 for conveying the lighter parts, thereby realizing the sorting and conveying of heavier parts and lighter parts.

[0044] As an implementation method in this embodiment, Figures 7 to 10 As shown, the tensioning adjustment assembly 7 includes a cylinder 71, which is mounted at one end of the roller bracket 4, and the output end of the cylinder 71 is rotatably connected to a piston sleeve cylinder 72, and a rotating shaft 73 is inserted into the interior of the piston sleeve cylinder 72, and the other end of the rotating shaft 73 is rotatably mounted inside the roller bracket 4, and a sleeve 74 is sleeved on the surface of the rotating shaft 73, and a long strip 75 is mounted on the surface of the sleeve 74, and multiple groups of long strips 75 are arranged around the surface of the sleeve 74, and one side of the long strip 75 is rotatably connected to a rotating plate 76, and multiple groups of rotating plates 76 are arranged on one side of the long strip 75, and one end of the rotating plate 76 is rotatably connected to a connecting strip 77, and a belt arc plate 78 is mounted on the end of the connecting strip 77. The surface of the belt arc plate 78 The surface is provided with an anti-slip pad, and one end surface of the connecting strip 77 is provided with two groups of blocks 79, and the inner walls of the two groups of blocks 79 are slidably connected with a slide cross 710, and a rotating seat 712 is installed on one side of the slide cross 710. The rotating seat 712 is installed inside the roller bracket 4, and the end of the rotating shaft 73 is rollingly connected with the rotating seat 712. A roller 711 is installed on one side of the block 79, and a partition is provided on the edge of the roller 711. One end of the belt 14 is sleeved on the surface of multiple groups of rollers 711. When the weighing sensor 68 measures the weight of the parts, the tensioning adjustment component 7 starts to run. First, the cylinder 71 is started, and the motor 11 drives the belt 14 to operate, and according to the weight of the parts The moving distance of the output end of the cylinder 71 is adjusted in amount so that the second conveyor belt 18 reaches the optimal tensioning degree. At this time, when the output end of the cylinder 71 moves, it drives the piston sleeve cylinder 72 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 in the direction of the bellows 13. When the sleeve 74 is pushed, the multiple groups of long blocks 75 installed on the surface of the sleeve 74 move with the sleeve 74. At the same time, the movement of the long block 75 drives the rotating plate 76 to move together. When the rotating plate 76 connected to one end of the long block 75 rotates, the rotating plate 76 connected to the other end of the rotating plate 76 The connecting bar 77 is acted upon by the block 79 installed on the end surface, and slides around inside the slide cross 710 until it stops at the output end of the cylinder 71. When the connecting bar 77 slides in the slide cross 710, the belt supporting arc plate 78 installed at the end of the connecting bar 77 pushes the second conveyor belt 18 on the surface to expand around. At this time, the second conveyor belt 18 becomes tight, and at the same time, the sliding of the connecting bar 77 causes the roller 711 to move around synchronously. At this time, the belt 14 sleeved on the surface of the roller 711 is expanding synchronously, and the drive of the motor 11 is faster, causing the rotating shaft 73 to rotate in the rotating seat 712, ensuring that the second conveyor belt 18 can also operate stably when the components are heavier.

[0045] As an implementation method in this embodiment, Figures 8 to 12 As shown, the heat dissipation and lubrication assembly 8 includes a hoop bracket 81, the hoop bracket 81 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 slide cross 710, one end of the hoop bracket 81 is installed with a cylindrical oil storage barrel 82, the cylindrical oil storage barrel 82 is sleeved on the surface of the rotating shaft 73, one end of the cylindrical oil storage barrel 82 is installed with an oil inlet 83, the bottom of the cylindrical oil storage barrel 82 is installed with an oil outlet 84, the open end of the oil outlet 84 is installed with an oil guide pipe 85, the other end of the oil guide pipe 85 is installed with an annular oil pipe rack 86, and the annular oil pipe rack 86 is installed At the end of the sleeve 74, the inner sliding connection of the cylindrical oil storage barrel 82 is provided with an oil push plate 810, and the end of the oil push plate 810 is provided with a force push plate 89, and a second spring 88 is provided between the force push plate 89 and the cylindrical oil storage barrel 82. The inner wall of the annular oil delivery pipe rack 86 is provided with multiple groups of oil nozzles 87. 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 delivery pipe rack 86 installed at the end of the sleeve 74 to move together. As the annular oil delivery pipe rack 86 moves, it starts to contact with the force push plate 89. When the force push plate 89 is subjected to the annular force, the oil delivery pipe rack 86 is pressed against the annular oil delivery pipe rack 86. When the oil pipe rack 86 is squeezed and pushed, the oil pushing plate 810 installed at one end of the force-bearing pushing 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-bearing pushing plate 89. However, due to the fixing effect of the clamp bracket 81 installed at one end of the slide cross 710, the cylindrical oil storage barrel 82 does not move. When the oil pushing plate 810 moves, the oil flows out through the bottom oil outlet 84 of the cylindrical oil storage barrel 82. The outflowing oil is transported to the annular oil delivery pipe rack 86 through the oil guide pipe 85, and then passes through the annular oil delivery pipe rack 86. Multiple groups of oil nozzles 87 installed on the inner wall spray oil onto the surface of the rotating shaft 73. When the output end of the cylinder 71 is pushed continuously, the oil nozzles 87 spray oil onto the rotating shaft 73 continuously. When the conveying device stops running, the cylinder 71 is reset. At the same time, the force-bearing push plate 89 is reset by the elastic force of the second spring 88. At the same time, the annular oil pipeline rack 86 is pushed to move together during the reset. At this time, the sleeve 74 and the force-bearing push plate 89 move the oil sprayed on the rotating shaft 73 together, which plays a role in maintaining the rotating shaft 73. The oil is then replenished through the oil inlet 83 to prepare for the next transportation of parts.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] When using this device, first check the stability between the double-layer lifting bracket 1, the glass bracket 2, the auxiliary bracket 3 and the roller bracket 4, then open the belt protective cover 12 to check whether the connection between the motor 11 and the belt 14 is loose, then clean the bellows 13 to ensure the internal cleanliness, then start the conveying device, set the parameters through the control center 10, and start the transportation of parts.

[0048] When the parts start to be transported, the calibration weighing assembly 6 starts to run. First, multiple sets of plug plates 61 are inserted into the roller bracket 4 installed on the top of the auxiliary bracket 3. Then, during the transportation of the parts on the conveyor belt 5, the parts first come into contact with the calibration plate 63. After the calibration plate 63 comes into contact with the parts, it begins to fold around the rotating shaft 62. At this time, the first spring 64 is squeezed and contracted by the end of the calibration plate 63. At this time, since the flip angle of the calibration plate 63 is limited, when one side of the calibration plate 63 is folded to the maximum angle, the parts are affected by the calibration plate. The pushing force of 63 and the conveying force of the conveyor belt 5 start to contact the other end of the calibration plate 63 during the movement, and then continue to be conveyed to the direction of the glass support 2 through the opening between the two sets of calibration plates 63. Subsequently, during the conveying process, the weight of the parts themselves presses down, causing the conveyor belt 5 carrying the parts to contact the weighing arc plate 67, and then the weighing arc plate 67 is pressed downward. At this time, the elastic frame 66 installed at the bottom of the weighing arc plate 67 contracts on the top of the installation fixing plate 65, and the weighing sensor 6 8 is pressed down to obtain weight data, and then transmits it to the control center 10 according to the weight data, and then the control center 10 transmits the instruction to the drive chain 15, and then the parts continue to be conveyed on the conveyor belt 5, contact and calibrate with the second set of calibration plates 63, 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, and then the drive chain 15 transports the heavier parts through the lifting and conveying platform 9 to the second conveyor belt 18 at the bottom of the double-layer lifting bracket 1 according to the instruction, and then the conveyor belt 5 equipped with the calibration weighing component 6 weighs the lighter parts, and the lighter parts are directly conveyed to the surface of the lifting and conveying platform 9 through the conveyor belt 5, and 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, and then the lighter parts are transported 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 conveying the lighter parts, thereby realizing the sorting and conveying of heavier parts and lighter parts.

[0049] When the weighing sensor 68 measures the weight of the parts, the tensioning adjustment assembly 7 starts to operate. First, the cylinder 71 is started, and the motor 11 drives the belt 14 to operate 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 optimal tension. At this time, when the output end of the cylinder 71 moves, it drives the piston sleeve cylinder 72 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 in the direction of the bellows 13. When the sleeve 74 is pushed, the multiple groups of long blocks 75 installed on the surface of the sleeve 74 move with the sleeve 74. At the same time, the movement of the long blocks 75 drives the rotating plate 76 to move together, and when 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 is affected by the stop block 79 installed on the end surface, and slides around inside the slide groove cross 710 until the output end of the cylinder 71 stops. When the connecting strip 77 slides in the slide 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, and the sliding of the connecting strip 77 causes the roller 711 to move around synchronously. At this time, the belt 14 sleeved on the surface of the roller 711 is expanded synchronously, and the drive of the motor 11 is faster, causing the rotating shaft 73 to rotate in the rotating seat 712, ensuring that the second conveyor belt 18 can also run stably when the parts are heavier.

[0050] 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 pipeline rack 86 installed at the end of the sleeve 74 to move together. As the annular oil pipeline rack 86 moves, it begins to contact the force-bearing push plate 89. When the force-bearing push plate 89 is squeezed by the annular oil pipeline rack 86, the oil push plate 810 installed at one end of the force-bearing 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-bearing push plate 89, and is affected by the fixing effect of the clamp bracket 81 installed at one end of the slide cross 710, the cylindrical oil storage barrel 82 does not move. When the oil push plate 810 moves, the oil passes through the cylindrical oil storage barrel 82. The oil flows out from the bottom outlet 84, and the outflowing oil is transported to the annular oil delivery pipe rack 86 through the oil guide pipe 85, and then sprayed onto the surface of the rotating shaft 73 through multiple groups of oil nozzles 87 installed on the inner wall of the annular oil delivery pipe rack 86. When the output end of the cylinder 71 is constantly pushing, the oil nozzles 87 are constantly spraying onto the rotating shaft 73. When the conveying device stops running, the cylinder 71 is reset. At the same time, the force-bearing push plate 89 is reset by the elastic force of the second spring 88, and at the same time, the annular oil delivery pipe rack 86 is pushed to move together during the reset. At this time, the sleeve 74 and the force-bearing push plate 89 move the oil sprayed on the rotating shaft 73 together, which plays a role in maintaining the rotating shaft 73. The oil is then replenished through the oil inlet 83 to prepare for the next transportation of parts.
