Description

Technical Field

[0001] This invention relates to the field of overhead conveying technology, specifically to an intelligent overhead conveying system for the production and processing of log furniture. Background Technology

[0002] Suspended transport is a transportation method that utilizes vertical space to move workpieces at a specified height, serving as a means of aerial storage and saving ground space.

[0003] Chinese patent CN118183202A, authorized and published on June 14, 2024, discloses an intelligent suspended conveying system for the production and processing of log furniture. This system includes a ring-shaped suspension rail with multiple transport components engaged on its outer side. Each transport component includes two symmetrically arranged guide wheels engaged on the outer side of the suspension rail. A series arm is fixed between the bottoms of the two guide wheels, and a mechanical claw is connected to the bottom of the series arm. In the aforementioned application, when the equipment is activated, the mechanical claw cannot grasp cylindrical or curved workpieces, reducing the equipment's applicability. Furthermore, during unloading, workpieces are prone to falling directly, causing damage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent suspended conveying system for the production and processing of log furniture, solving the problems mentioned in the background section. To achieve the above objectives, this invention is implemented through the following technical solution: an intelligent suspended conveying system for the production and processing of log furniture, comprising:

[0005] An outer track has a roller movably connected inside; an inner track has a roller movably connected inside, and a C-shaped bracket is rotatably connected to the outside of the roller. An electric telescopic rod is fixedly connected to the bottom of the C-shaped bracket, and a stop block is fixedly connected to the bottom of the electric telescopic rod. A movable gripper device is hinged to the outside of the stop block; a hydraulic block is fixedly connected to the top of the stop block, and a push block is movably connected to the top of the hydraulic block. The interior of the hydraulic block is connected to the interior of a second hydraulic block via a hose. The second hydraulic block is fixedly connected to the movable gripper device via a fixed block. A push block is movably connected to the front of the second hydraulic block, and a positioning block is hinged to the front of the push block. A push block is fixedly connected to the rear of the positioning block, and a hydraulic block is movably connected to the rear of the push block. The outside of the third hydraulic block is movably connected to the positioning block. By setting up positioning block one and positioning block two, when the equipment starts the electric telescopic rod, positioning block one and positioning block two will automatically fit against the outer surface of the workpiece, so that the equipment can clamp cylindrical workpieces of different diameters, thereby increasing the range of use of the equipment and saving costs.

[0006] Preferably, the transmission component includes a second hose, a fourth hydraulic block, a fourth push block, a rotating block, a first rotating shaft, and a second fixed block. The third hydraulic block communicates with the interior of the fourth hydraulic block through the second hose. The bottom of the movable gripper device is fixedly connected to the second fixed block. The second fixed blocks are rotatably connected to the first rotating shaft through the first positioning block. The top of the first rotating shaft is fixedly connected to the rotating block. The outer side of the rotating block is fixedly connected to the fourth push block. The rear side of the fourth push block is movably connected to the fourth hydraulic block.

[0007] Preferably, a spring is fixedly connected between the bottom of the electric telescopic rod and the stop block, the outer side of the hydraulic block is fixedly connected to the movable gripper device, an auxiliary unloading assembly is movably connected inside the movable gripper device, and a lubrication assembly is movably connected to the top of the C-shaped bracket.

[0008] Preferably, there are two rollers, three push blocks, three hydraulic blocks, three hoses, three hydraulic blocks, three fixing blocks, three positioning blocks, three hydraulic blocks, three hydraulic blocks, three hoses, and six hydraulic blocks, with two hydraulic blocks forming a group. There are twelve fixing blocks, with four fixing blocks forming a group. There are six positioning blocks, with two positioning blocks forming a group.

[0009] Preferably, the auxiliary unloading assembly includes a telescopic rod base, a movable rod, a third fixed block, a second spring, a fourth fixed block, a second rotating shaft, and a second roller. The top of the telescopic rod base is fixedly connected to the outer surface of the movable gripper device. The movable rod is movably connected to the front side of the telescopic rod base. The third fixed block is fixedly connected to the side of the movable rod. The second spring is fixedly connected between the third fixed block and the inner side of the movable gripper device. Two fourth fixed blocks are fixedly connected to the front side of the movable rod. The two fourth fixed blocks are rotatably connected to the second roller via the second rotating shaft. By setting up the auxiliary unloading assembly, when the equipment starts unloading, the movable gripper device opens outward under the action of the abutment block. Due to the release of elastic potential energy by the second spring, the movable rod remains in an outward-extending state, keeping the second roller close to the outer side of the workpiece. Only when the movable gripper device is fully opened, causing the second roller to move away from the outer side of the workpiece, is unloading completed. This allows the equipment to delay unloading, giving the unloading personnel time to operate and preventing the workpiece from falling directly.

[0010] Preferably, the number of telescopic rod bases is three, each telescopic rod base is circumferentially distributed about the center of the abutment block, the number of movable rods is three, the number of fixed blocks three is three, the number of fixed blocks four is six, every two fixed blocks four form a group, and the number of rollers two is three.

[0011] Preferably, the movable gripper device is movably connected to the movable rod by having a movable groove inside.

[0012] Preferably, the lubrication assembly includes a hose three, a hydraulic block five, a push block five, a valve, an oil reservoir, an oil outlet, and an oil inlet. The side of the outer hydraulic block one is fixedly connected to one end of the hose three, and the other end of the hose three is fixedly connected to the outer side of the hydraulic block five. The bottom of the hydraulic block five is movably connected to the push block five, and the inner side of the push block five is fixedly connected to the valve. The top of the C-shaped bracket is fixedly connected to the oil reservoir, and the outer side of the oil reservoir is movably connected to the valve. The rear side of the oil reservoir is fixedly connected to the oil outlet, and the top of the oil reservoir is fixedly connected to the oil inlet. With this lubrication assembly, the valve automatically opens during loading or unloading, lubricating the rotating shaft of the roller one, thereby reducing manual maintenance and extending the equipment's service life.

[0013] Preferably, there are two hydraulic blocks, two push blocks, two valves, two oil storage tanks, two oil outlets, and two oil inlets.

[0014] Preferably, the top of the hose three is fixedly connected to two branch pipes, and the branch pipes are fixedly connected to the hydraulic block five.

[0015] This invention provides an intelligent suspended conveying system for the production and processing of log furniture. It has the following beneficial effects:

[0016] (1) When loading the intelligent suspended conveyor system for the production and processing of log furniture, the electric telescopic rod is started, and in conjunction with push block one, hydraulic block one, hose one, hydraulic block two, fixing block one, push block two, positioning block one, hydraulic block three, hose two, hydraulic block four, push block four, and rotating block, positioning block one moves inward to fit the side of the workpiece, and positioning block two rotates to fit the bottom side of the workpiece, so that the equipment fixes the columnar workpiece.

[0017] (2) When unloading, the intelligent suspended conveyor system for the production and processing of log furniture starts the electric telescopic rod, which works in conjunction with the movable gripper device, telescopic rod base, movable rod, spring two, and roller two to make the movable gripper device open outward under the action of the block. As spring two releases elastic potential energy, the movable rod remains in an outward extension state, and roller two is pressed tightly against the outside of the workpiece, so that the workpiece will not fall directly.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1, please refer to Figures 1-4 An intelligent overhead conveyor system for the production and processing of log furniture, comprising:

[0034] An outer track 100 is provided, with rollers 300 movably connected inside. The outer track 100 allows the equipment to move along its direction. An inner track 200 is provided, allowing the equipment to move along its direction while also making the movement more stable. Rollers 300 are movably connected inside the inner track 200, allowing the movable gripper device 600 to move along both the outer track 100 and the inner track 200. A C-shaped bracket 400 is rotatably connected to the outside of rollers 300, further stabilizing the movement of the equipment body. The bottom of the C-shaped bracket 400 is fixed. An electric telescopic rod 500 is fixedly connected. A spring 800 is fixedly connected between the bottom of the electric telescopic rod 500 and the stop block 700. The spring 800 is set to buffer the up and down movement of the stop block 700. The outer side of the hydraulic block 909 is fixedly connected to the movable gripper device 600. The movable gripper device 600 is set to allow the device to grip or put down the workpiece. An auxiliary unloading component 1000 is movably connected inside the movable gripper device 600. A lubrication component 1100 is movably connected to the top of the C-shaped bracket 400. The bottom of the electric telescopic rod 500 is fixedly connected to the stop block 700. The movable gripper device 600 is hinged to the outer side of the stop block 700.A hydraulic block 902 is fixedly connected to the top of the abutment block 700. A push block 901 is movably connected to the top of the hydraulic block 902. The interior of the hydraulic block 902 is connected to the interior of the hydraulic block 904 via a hose 903. The hydraulic block 904 is fixedly connected to the movable gripper device 600 via a fixed block 905. A push block 906 is movably connected to the front side of the hydraulic block 904. A positioning block 907 is hinged to the front side of the push block 906. A push block 908 is fixedly connected to the rear side of the positioning block 907. The rear side of the push block 908 is movably connected to... A hydraulic block 3 909 is connected, and the outer side of the hydraulic block 3 909 is movably connected to the positioning block 2 916 via a transmission component. The transmission component includes a hose 2 910, a hydraulic block 4 911, a push block 4 912, a rotating block 913, a rotating shaft 1 914, and a fixed block 2 915. The hydraulic block 3 909 communicates with the interior of the hydraulic block 4 911 via the hose 2 910. The bottom of the movable gripper device 600 is fixedly connected to the fixed block 2 915, and the fixed blocks 2 915 are rotatably connected to the positioning block 2 916 via the rotating shaft 1 914. The top of the rotating shaft 1 914 is fixed. A rotating block 913 is connected, and a push block 912 is fixedly connected to the outside of the rotating block 913. A hydraulic block 911 is movably connected to the rear side of the push block 912. There are two rollers 300, three push blocks 901, three hydraulic blocks 902, three hoses 903, three hydraulic blocks 904, three fixing blocks 905, three push blocks 906, three positioning blocks 907, three hydraulic blocks 909, and several hoses 910. The equipment consists of three hydraulic blocks (911, 4), six hydraulic blocks (911, 4), two fixed blocks (915, 2), twelve fixed blocks (915, 2), and six positioning blocks (916, 2), two positioning blocks (916, 2). Positioning blocks (907, 1) and (916, 2) are also included. When the electric telescopic rod (500) is activated, positioning blocks (907, 1) and (916, 2) automatically conform to the outer surface of the workpiece. This allows the equipment to clamp cylindrical workpieces of different diameters, increasing its applicability and saving costs.

[0035] During operation, when the equipment begins loading, the movable gripper device 600, driven by roller 300, moves along the outer track 100 and inner track 200 to the loading port. At this time, the electric telescopic rod 500 is activated, causing the stop block 700 to move upward, which in turn moves the hydraulic block 902 upward and the push block 901 to retract downward. This increases the internal pressure of the hydraulic block 902, which is then transmitted through hose 903 to the hydraulic block 904, further increasing the internal pressure. This causes the push block 906 to move inward, bringing the positioning block 907 into contact with the outer side of the workpiece. Simultaneously, positioning block 907 rotates inward until it is level with the outer side of the movable gripper device 600, causing push block 908 to move inward, increasing the internal pressure of hydraulic block 909. This internal pressure is then transmitted through hose 910 to hydraulic block 911, increasing the internal pressure of hydraulic block 911. This causes push block 912 to push outward, rotating block 913 to rotate, rotating shaft 914 to rotate, and positioning block 916 to rotate inward to clamp the bottom outer side of the cylindrical workpiece. This allows the device to clamp cylindrical workpieces of different diameters, increasing its applicability and saving costs.

[0036] Example 2, please refer to Figures 1-6Based on Embodiment 1, the auxiliary unloading assembly 1000 includes a telescopic rod base 1001, a movable rod 1002, a fixed block 3 1003, a spring 2 1004, a fixed block 4 1005, a rotating shaft 2 1006, and a roller 2 1007. The top of the telescopic rod base 1001 is fixedly connected to the outer surface of the movable gripper device 600, and the movable rod 1002 is movably connected to the front side of the telescopic rod base 1001. The movable gripper device 600 has a movable groove inside it that connects with... The movable rod 1002 is movably connected, and a fixing block 3 1003 is fixedly connected to the side of the movable rod 1002. A spring 2 1004 is fixedly connected between the fixing block 3 1003 and the inner side of the movable gripper device 600. The spring 2 1004 is configured to convert the force of the movable rod 1002 moving inward into the elastic potential energy of the spring 2 1004. Two fixing blocks 4 1005 are fixedly connected to the front side of the movable rod 1002. The two fixing blocks 4 1005 are connected to each other via a rotating shaft 2 1006. Roller 2 1007 is rotatably connected, and roller 2 1007 is set so that the outer surface of the workpiece is in contact with roller 2 1007. There are three telescopic rod bases 1001, and each telescopic rod base 1001 is circumferentially distributed about the center of the abutment block 700. There are three movable rods 1002, three fixed blocks 3 1003, and six fixed blocks 4 1005, with two fixed blocks 4 1005 forming a group. There are three rollers 2 1007, which are set to assist unloading. When component 1000 starts unloading, the movable gripper device 600 opens outward under the action of the stop block 700. As the spring 1004 releases its elastic potential energy, the movable rod 1002 remains in an outward-extending state, keeping the roller 1007 close to the outside of the workpiece. Only when the movable gripper device 600 is fully opened, and the roller 1007 moves away from the outside of the workpiece, is the unloading completed. This allows the equipment to delay unloading, giving the unloading personnel time to operate the unloading process and preventing the workpiece from falling directly.

[0037] In use, based on Example 1, when the equipment begins unloading, the electric telescopic rod 500 is activated, causing the stop block 700 to move downwards and the movable gripper device 600 to open outwards. At this time, the second spring 1004 releases its elastic potential energy, causing the movable rod 1002 to extend inwards from the telescopic rod base 1001, so that the second roller 1007 always clamps the surface of the workpiece. This prevents the workpiece from falling directly when the movable gripper device 600 opens outwards, thus protecting the workpiece. When the stop block 700 continues to move downwards, the movable gripper device 600 fully opens. At this time, due to the limited extension length of the movable rod 1002, the second roller 1007 begins to move away from the outside of the workpiece, causing the workpiece to fall. This allows the unloading personnel sufficient time to prepare for unloading before the workpiece falls, thereby protecting the workpiece and avoiding loss.

[0038] Example 3, please refer to Figures 1-8Based on Embodiments 1 and 2, the lubrication assembly 1100 includes a hose 1101, a hydraulic block 1102, a push block 1103, a valve 1104, an oil reservoir 1105, an oil outlet 1106, and an oil inlet 1107. The side of the outer hydraulic block 902 is fixedly connected to one end of the hose 1101, and the other end of the hose 1101 is fixedly connected to the outer side of the hydraulic block 1102. The hose 1101 is configured to allow communication between the interior of the hydraulic block 1102 and the interior of the hydraulic block 902. Two branch pipes are fixedly connected to the top of the hose 1101, and these branch pipes are fixedly connected to the hydraulic block 1102. The bottom of the hydraulic block 1102 is movably connected to the push block 1103, and the inner side of the push block 1103 is fixedly connected to the valve 1104. The top of the C-shaped bracket 400... An oil reservoir 1105 is fixedly connected, and a valve 1104 is movably connected to the outside of the oil reservoir 1105. An oil outlet 1106 is fixedly connected to the rear side of the oil reservoir 1105, and an oil inlet 1107 is fixedly connected to the top of the oil reservoir 1105. The oil inlet 1107 is provided to allow the lubricating oil in the oil reservoir 1105 to be replenished. There are two hydraulic blocks 1102, two push blocks 1103, two valves 1104, two oil reservoirs 1105, two oil outlets 1106, and two oil inlets 1107. A lubrication assembly 1100 is provided. When the equipment is loading or unloading, the valve 1104 automatically opens and closes to lubricate the rotating shaft of the roller 300, thereby reducing manual maintenance and extending the service life of the equipment.

[0039] In use, based on Embodiments 1 and 2, when the equipment begins loading, the electric telescopic rod 500 is activated, causing the stop block 700 to move upward, increasing the internal pressure of hydraulic block 902. Excess pressure in hydraulic block 902 is then transmitted through hose 3 1101 to hydraulic block 5 1102, further increasing its internal pressure. This causes push block 5 1103 to push outward, automatically closing valve 1104. When unloading, the electric telescopic rod 500 is activated, causing the stop block 700 to move downward, decreasing the internal pressure of hydraulic block 902. This pressure is then transmitted through hose 3 1101 to hydraulic block 5 1102, causing push block 5 1103 to retract inward, automatically opening valve 1104. This lubricates the rotating shaft of roller 300, reducing manual maintenance and extending the equipment's service life.

[0040] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
