Description

Technical Field

[0001] The utility model relates to a conveying device, in particular to an inserting roller type high-efficiency loading and unloading machine. Background Art

[0002] In industrial production, for workpieces that need to be automatically loaded and unloaded, for workpieces arranged in a single layer on a beam frame, they can be directly moved above the workpieces by a manipulator for grasping and then transferred, or a lifting mechanism can be used to lift the workpieces upward from below the beam frame for transfer. In order to improve production efficiency, there is currently a situation where multiple layers of workpieces are arranged vertically on the beam frame. However, due to the structural interference of the beam frame, it is difficult for the current manipulator or lifting mechanism to move into the positions where each layer of workpieces is located. Therefore, there is an urgent need for a loading and unloading machine that can load and unload multiple layers of workpieces on the beam frame. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an inserting roller type high-efficiency loading and unloading machine to solve one or more technical problems in the prior art and at least provide a beneficial option or create conditions.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] An inserting roller type high-efficiency loading and unloading machine, comprising: a frame; a lifting frame that can move up and down in the frame; a roller type conveying device, including a sliding frame, a conveying roller and a roller block, the roller block is rotatably connected to one side of the lifting frame to be, the conveying roller is rotatably connected to the sliding frame, wherein the sliding frame can move in a direction close to the roller block so that the end of the conveying roller is cooperatively connected to the roller block; or the sliding frame can move in a direction away from the roller block so that the end of the conveying roller is disengaged from the roller block, and a plurality of the conveying rollers and the roller blocks are respectively arranged at intervals along a straight line direction.

[0006] The technical solution has at least the following beneficial effects: The peripheral beam with multiple layers of workpieces above and below is transferred into the frame and located between the idler blocks and the conveyor rollers. When it is necessary to take out the multiple layers of workpieces on the beam, the lifting frame first moves below the beam, and then the carriage moves towards the idler block, so that the end of the conveyor roller close to the idler block is cooperatively connected to the idler block facing it. At this time, the conveyor roller is located below the lowermost layer of workpieces. Then the lifting frame moves upward, so that the multiple conveyor rollers push the lowermost layer of workpieces upward away from the beam. Then the conveyor roller rotates to translate the workpiece out of the beam. After the transfer of this layer of workpiece is completed, the lifting frame moves upward, so that the conveyor roller moves up one layer. At this time, the conveyor roller will not interfere with the beam. Repeating the above operation can realize the blanking of each layer of workpieces. In this way, the conveyor rollers used for workpiece transfer are disassembled and moved up and down to different layers, and then the conveyor rollers are reassembled in place, so that different layer positions can be reached, and the loading and unloading of multiple layers of workpieces can be realized, which is beneficial to realize the automatic loading and unloading of multiple layers of workpieces and improve production efficiency.

[0007] As a further improvement of the above technical solution, a conical protrusion is formed at the end of the idler block facing the conveyor roller. The end of the conveyor roller facing the idler block is a hollow structure, and the carriage can move in the direction close to the idler block so that the conical protrusion is relatively inserted into the conveyor roller. The conical protrusion on the idler block can play a guiding role. When the carriage moves in the direction close to the idler block, the conical protrusion is inserted into the hollow end of the conveyor roller to ensure the cooperation between the idler block and the conveyor roller, and is beneficial to ensure that the idler block and the conveyor roller are on the same axis, so that both ends of the conveyor roller have rotational support during operation, improving the stability of the conveyor roller during rotation. When it is necessary to release the cooperation between the conveyor roller and the idler block, the conveyor roller can be moved away from the idler block.

[0008] As a further improvement of the above technical solution, a connecting sleeve is connected inside the end of the conveyor roller facing the idler block, and the carriage can move in the direction close to the idler block so that the conical protrusion is relatively inserted into the connecting sleeve. When the conical protrusion is inserted into the hollow conveyor roller, the connecting sleeve first contacts the outer surface of the conical protrusion. The use of the connecting sleeve can strengthen the structural strength of the end of the conveyor roller, reduce the wear of the conical protrusion on the end of the conveyor roller, and is beneficial to improving the structural stability of the conveyor roller during long-term use.

[0009] As a further improvement of the above technical solution, idler wheels are respectively rotatably connected below the multiple conveyor rollers on the carriage, and the multiple idler wheels respectively support the bottom sides of the multiple conveyor rollers. The idler wheels can assist in supporting the conveyor roller, reducing the stress on the connection between the end of the conveyor roller and the carriage, and reducing the risk of deformation of the conveyor roller, improving the service life of the conveyor roller. When the conveyor roller moves in the direction close to or away from the idler block, the conveyor roller can drive the idler wheel to rotate, thereby reducing the friction between the two and making the movement of the conveyor roller smoother.

[0010] As a further improvement of the above technical solution, annular grooves are respectively formed around the outer circumferences of the plurality of carrier rollers, and the plurality of conveyor rollers are respectively clamped into the annular grooves. The carrier rollers can surround and fit the bottom sides of the conveyor rollers by using the positions of the annular grooves, thereby increasing the contact area between the carrier rollers and the conveyor rollers, and preventing the conveyor rollers from horizontally shifting during the translation process, and further improving the stability of supporting the conveyor rollers.

[0011] As a further improvement of the above technical solution, limiting grooves are respectively connected below the plurality of conveyor rollers on the carriage, and both sides of the plurality of limiting grooves extend upward to both sides of the conveyor rollers facing them. The two sides of the limiting groove extend upward to block and limit the deviation of the conveyor roller at the two sides of the conveyor roller, so as to further improve the stability of the conveyor roller during the translation process, effectively prevent the conveyor roller from deviating from the support of the carrier roller, and improve the overall working stability.

[0012] As a further improvement of the above technical solution, the carriage is slidably connected to the lifting frame, a first motor is connected to the bottom side of the carriage, the first motor is drivingly connected with a gear, a rack is connected to the lifting frame, and the gear meshes with the rack. When the carriage needs to approach or move away from the roller block, the first motor drives the gear to rotate. By using the meshing of the gear and the rack, the gear can walk on the rack, thereby realizing the translational movement of the carriage on the lifting frame.

[0013] As a further improvement of the above technical solution, the lifting frame is slidably connected in the machine frame in the up and down direction, a second motor is connected to the machine frame, a transmission unit is arranged between the lifting frame and the machine frame, the transmission unit includes a transmission shaft, a sprocket, a chain and a counterweight plate, the transmission shaft is rotatably connected to the machine frame, the second motor is drivingly connected to the transmission shaft, a sprocket is connected to the transmission shaft, one end of the chain is connected to the counterweight plate, and the other end of the counterweight plate bypasses the sprocket and is connected to the lifting frame. When the lifting frame needs to move up and down, the second motor works to drive the sprocket to rotate through the transmission shaft. Since the sprocket and the chain cooperate with each other, and their two ends are respectively connected to the counterweight plate and the lifting frame to straighten the chain. When the sprocket rotates forward, the lifting frame can be driven to move upward through the chain, and at this time the counterweight plate moves downward; when the sprocket rotates reversely, the lifting frame can be driven to move downward through the chain, and at this time the counterweight plate moves upward, so that the lifting frame can be driven to move up and down.

[0014] As a further improvement of the above technical solution, the number of the transmission units is not less than two, and the second motors are respectively drivingly connected to a plurality of the transmission shafts. The transmission units are respectively arranged between a plurality of positions of the frame and the lifting frame, which can improve the stability of the up-and-down movement of the lifting frame, and the power is respectively transmitted by the second motors through a plurality of transmission shafts, so as to provide a driving force for the synchronous up-and-down movement of the lifting frame at different positions, and enable the lifting frame to move up and down smoothly.

[0015] As a further improvement of the above technical solution, a plurality of transition rollers are arranged on the downstream side of the conveying roller on the lifting frame. The plurality of transition rollers can fill the space between the conveying roller and the next working station. After the workpiece is removed by the plurality of conveying rollers, the workpiece is supported by the plurality of transition rollers and transferred to the next working station under the action of inertia.

[0025] Referring to Figure 1 and Figure 2 , an inserting roller type high-efficiency loading and unloading machine, comprising a frame 100, a lifting frame 200 and a roller conveying device. Among them, the lifting frame 200 can move up and down in the frame 100; the roller conveying device includes a sliding frame 310, a conveying roller 320 and a roller block 330. The roller block 330 is rotatably connected to one side of the lifting frame 200 to be lifted, and the conveying roller 320 is rotatably connected to the sliding frame 310. Among them, the sliding frame 310 can move in a direction close to the roller block 330 so that the end of the conveying roller 320 is cooperatively connected to the roller block 330; or the sliding frame 310 can move in a direction away from the roller block 330 so that the end of the conveying roller 320 is disengaged from the roller block 330. The conveying roller 320 and the roller block 330 are respectively arranged at intervals in a straight line direction with multiple ones.

[0026] As described above, the peripheral beam frame with multiple layers of workpieces is transferred into the frame 100 and located between the roller blocks 330 and the conveyor rollers 320. When it is necessary to take out the multiple layers of workpieces on the beam frame, the lifting frame 200 first moves to the lower part of the beam frame, and then the carriage 310 moves towards the roller block 330, so that the end of the conveyor roller 320 close to the roller block 330 is cooperatively connected to the roller block 330 facing it. At this time, the conveyor roller 320 is located below the lowermost layer of workpieces. Then, the lifting frame 200 moves upward, so that the multiple conveyor rollers 320 push the lowermost layer of workpieces upward away from the beam frame. Then, the conveyor roller 320 rotates to translate the workpiece out of the beam frame. After the transfer of this layer of workpiece is completed, the lifting frame 200 moves upward, so that the conveyor roller 320 moves up one layer. At this time, the conveyor roller 320 will not interfere with the beam frame. By repeating the above operations, the blanking of each layer of workpieces can be realized. In this way, the conveyor rollers 320 used for workpiece transfer are disassembled and moved up and down to different layers, and then the conveyor rollers 320 are reassembled in place, so as to reach different layer positions and realize the loading and unloading of multiple layers of workpieces, which is beneficial to realizing the automatic loading and unloading of multiple layers of workpieces and improving production efficiency.

[0027] Naturally, a drive source for driving the conveyor roller 320 is configured on the carriage 310 to drive the conveyor roller 320 to rotate on the carriage 310. For example, a drive motor is connected to the carriage 310. Taking the rotation direction of the conveyor roller 320 in the horizontal direction as the first direction and the direction in which the conveyor rollers 320 are arranged at intervals along the horizontal straight line direction as the second direction, a plurality of rotating seats are arranged on the frame 100 along the second direction. At this time, the end parts of the plurality of conveyor rollers 320 are respectively rotatably connected to the plurality of rotating seats, and transmission wheels are respectively connected to the plurality of transmission rollers. The drive motor is drivingly connected with a driving wheel, and a transmission chain 343 is meshed between the plurality of transmission wheels and the driving wheel. The drive motor drives the transmission chain 343 to perform a rotary motion through the driving wheel, so as to drive the plurality of transmission wheels to rotate.

[0028] When the conveyor roller 320 approaches the roller block 330, a stable connection is formed between the roller block 330 and the end of the conveyor roller 320, so as to stabilize the conveyor roller 320. There can be various ways of cooperative connection between the two. For example, the end of the conveyor roller 320 is connected to the roller block 330 by means of a buckle. In this embodiment, as Figure 3As shown, a conical protrusion 331 is formed at the end of the idler block 330 facing the conveyor roller 320. The end of the conveyor roller 320 facing the idler block 330 is a hollow structure. The carriage 310 can move in the direction close to the idler block 330, so that the conical protrusion 331 is relatively inserted into the conveyor roller 320. In practical applications, the conical protrusion 331 and the idler block 330 are integrally formed. The shape of the conical protrusion 331 is conical, and its outer diameter gradually decreases in the direction close to the conveyor roller 320. The conical protrusion 331 on the idler block 330 can play a guiding role. When the carriage 310 moves in the direction close to the idler block 330, the conical protrusion 331 is inserted into the hollow end of the conveyor roller 320, ensuring the mutual cooperation between the idler block 330 and the conveyor roller 320, and facilitating the alignment of the idler block 330 and the conveyor roller 320 on the same axis, so that both ends of the conveyor roller 320 have rotational support during operation, improving the stability of the conveyor roller 320 during rotation. When it is necessary to release the cooperation between the conveyor roller 320 and the idler block 330, the conveyor roller 320 can be moved in the direction away from the idler block 330.

[0029] The conveyor roller 320 is a hollow structure, and its end can be directly matched with the conical protrusion 331. In order to reduce the inner diameter of the hollow part of the conveyor roller 320 and reduce the direct friction with the end of the conveyor roller 320, in this embodiment, a connecting sleeve 321 is connected inside the end of the conveyor roller 320 facing the idler block 330. The carriage 310 can move in the direction close to the idler block 330, so that the conical protrusion 331 is relatively inserted into the connecting sleeve 321. When the conical protrusion 331 is inserted into the hollow conveyor roller 320, the connecting sleeve 321 first contacts the outer surface of the conical protrusion 331. Using the connecting sleeve 321 can strengthen the structural strength of the end of the conveyor roller 320, reduce the wear of the conical protrusion 331 on the end of the conveyor roller 320, and is beneficial to improving the structural stability of the conveyor roller 320 during long-term use.

[0030] In order to improve the stability of the conveyor roller 320 when approaching or moving away from the idler block 330, in this embodiment, a supporting wheel 311 is rotatably connected below each of the conveyor rollers 320 on the carriage 310. The length direction of the rotation axis of the idler block 330 is the first direction, and the supporting wheels 311 respectively support the bottom sides of the conveyor rollers 320. The supporting wheels 311 can assist in supporting the conveyor roller 320, reducing the stress on the connection between the end of the conveyor roller 320 and the carriage 310, and reducing the risk of deformation of the conveyor roller 320, improving the service life of the conveyor roller 320. When the conveyor roller 320 moves in the direction close to or away from the idler block 330, the conveyor roller 320 can drive the supporting wheel 311 to rotate, thereby reducing the friction between the two and making the movement of the conveyor roller 320 smoother.

[0031] The outer periphery of the supporting roller 311 can be an annular surface. However, when the conveying roller 320 moves relative to the supporting roller 311, relative slippage is likely to occur between the conveying roller 320 and the supporting roller 311, that is, the conveying roller 320 moves relative to the supporting roller 311 along the second direction. To improve the stability of supporting the conveying roller 320, annular grooves are respectively provided around the outer peripheries of the plurality of supporting rollers 311, and the plurality of conveying rollers 320 are respectively engaged in the annular grooves. The supporting roller 311 can surround and fit the bottom side of the conveying roller 320 by using the position of the annular groove, thereby increasing the contact area between the supporting roller 311 and the conveying roller 320, and preventing the conveying roller 320 from horizontally shifting during translation, further improving the stability of supporting the conveying roller 320. Further, the cross-sectional shape of the annular groove is similar to the cross-sectional shape of the bottom side of the conveying roller 320, so that the conveying roller 320 can better fit with the annular groove on the outer periphery of the supporting roller 311.

[0032] Further, to better prevent the conveying roller 320 from disengaging from the supporting roller 311, in this embodiment, limiting grooves are respectively connected below the plurality of conveying rollers 320 on the carriage 310, and both sides of the plurality of limiting grooves extend upward to both sides of the conveying roller 320 opposite thereto. The two sides of the limiting groove extend upward to block and limit the offset of the conveying roller 320 at both sides of the conveying roller 320, so as to further improve the stability of the conveying roller 320 during translation, effectively prevent the conveying roller 320 from deviating from the support of the supporting roller 311, and improve the overall working stability. In practical applications, the limiting groove is a U-shaped frame structure, forming a groove structure with an upward groove opening, and the two side plates of the limiting groove can extend upward respectively, so as to form two side plates spaced apart on both sides of the conveying roller 320. When the conveying roller 320 displaces too much along the second direction, it will be blocked by the side plates, thus effectively preventing the conveying roller 320 from disengaging.

[0033] A structure for driving the carriage 310 to reciprocate linearly is provided inside the lifting frame 200, and there are various structural forms, such as cylinders, electric lead screws or hydraulic cylinders, etc. When the moving stroke of the carriage 310 is large, the lengths of the required cylinders, electric lead screws or hydraulic cylinders are also large, and at this time, a large space volume will be occupied. In order to optimize the internal structure design, in this embodiment, the carriage 310 is slidably connected to the lifting frame 200, a first motor 210 is connected to the bottom side of the carriage 310, the first motor 210 is drivingly connected with a gear 220, a rack 230 is connected to the lifting frame 200, and the gear 220 meshes with the rack 230. When the carriage 310 needs to approach or move away from the roller block 330, the first motor 210 drives the gear 220 to rotate. By utilizing the meshing of the gear 220 and the rack 230, the gear 220 can be made to move on the rack 230, thereby realizing the translational movement of the carriage 310 on the lifting frame 200. In practical applications, taking one gear 220 and one rack 230 as the transmission components of the carriage 310, at least two sets of carriage 310 transmission components can be provided between the carriage 310 and the lifting frame 200 along the second direction, so as to provide driving forces in all directions of the carriage 310 and improve the stability of the sliding of the carriage 310. And for multiple sets of carriage 310 transmission components, the first motor 210 provides the output power, so as to realize the synchronous rotation of multiple gears 220.

[0034] A structure for driving the lifting frame 200 to move up and down is provided inside the frame 100, such as a cylinder, an electric lead screw, or a hydraulic cylinder, etc. Similarly, when the stroke of the lifting frame 200 moving in the up and down direction is relatively large, the length of the required cylinder, electric lead screw, or hydraulic cylinder is also relatively large. At this time, it will occupy a relatively large space volume. To optimize the internal structure design, in this embodiment, the lifting frame 200 is slidably connected to the inside of the frame 100 in the up and down direction. A second motor 350 is connected to the frame 100. A transmission unit is provided between the lifting frame 200 and the frame 100. The transmission unit includes a transmission shaft 341, a sprocket 342, a chain 343, and a counterweight plate 344. The transmission shaft 341 is rotatably connected to the frame 100. The second motor 350 is drivingly connected to the transmission shaft 341. A sprocket 342 is connected to the transmission shaft 341. One end of the chain 343 is connected to the counterweight plate 344. The other end of the counterweight plate 344 bypasses the sprocket 342 and is connected to the lifting frame 200. In practical applications, the counterweight plate 344 can also be slidably connected to the inside of the lifting frame 200 in the up and down direction, thereby improving the stability of its movement. When the lifting frame 200 needs to move up and down, the second motor 350 works, drives the sprocket 342 to rotate through the transmission shaft 341. Since the sprocket 342 cooperates with the chain 343, and its two ends are respectively connected to the counterweight plate 344 and the lifting frame 200, the chain 343 is straightened. When the sprocket 342 rotates forward, the lifting frame 200 can be driven to move upward through the chain 343. At this time, the counterweight plate 344 moves downward; when the sprocket 342 rotates reversely, the lifting frame 200 can be driven to move downward through the chain 343. At this time, the counterweight plate 344 moves upward. In this way, the lifting frame 200 can be driven to move up and down.

[0035] When the number of transmission units is one, when the overall load of the lifting frame 200 is relatively large, the stability of driving the lifting frame 200 to move by a single transmission unit is somewhat lacking. Therefore, in this embodiment, the number of transmission units is not less than two, and the second motor 350 is respectively drivingly connected to a plurality of the transmission shafts 341. Transmission units are respectively arranged between multiple positions of the frame 100 and the lifting frame 200, which can improve the stability of the lifting frame 200 moving up and down. And the power is respectively transmitted by the second motor 350 through a plurality of transmission shafts 341, so as to provide a driving force for the synchronous up and down movement of the lifting frame 200 at different positions, so that the lifting frame 200 moves up and down smoothly.

[0036] In some embodiments, the number of drive units is four. Two drive units are arranged along the first direction respectively, and taking the two drive units arranged along the first direction as a lifting drive assembly, two lifting drive assemblies can be arranged along the second direction. In this way, the four drive units apply forces to the lifting frame 200 from the four corner positions respectively, effectively improving the stability of the lifting frame 200. At this time, the second motor 350 first outputs power to a rotating shaft, and at each end of the rotating shaft, the power is transmitted to the transmission shafts 341 in the two drive units through the gears 220 respectively to achieve power transmission.

[0037] When the distance between the conveyor roller 320 on the downstream side of the conveyor and the frame 100 is small and the volume of the workpiece is large, the workpiece can be directly output outward without transfer. When the distance between them is large or the volume of the workpiece is small, a structure for outward transfer of the workpiece is required. Specifically, a plurality of transition rollers 240 are arranged on the downstream side of the conveyor roller 320 on the lifting frame 200. The plurality of transition rollers 240 can fill the space between the conveyor roller 320 and the next working station. After the plurality of conveyor rollers 320 move out the workpiece, the workpiece is supported by the plurality of transition rollers 240 and transferred to the next working station under the action of inertia. Therefore, the lifting frame 200 drives the conveyor roller 320 to reach different layers, and can quickly send out products on different layers. After all products are conveyed, the conveyor roller 320 is withdrawn, and the lifting frame 200 is lifted to the top, then the beam frame can be moved out.

[0038] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
