Description

Technical Field

[0001] The present invention relates to the technical field of stacker production, and more particularly to an automatic stacker. Background Art

[0002] Stacking is the pinyin of stacking, which refers to the accumulation of items, or the regular placement of items to form a stack. Stacking has various forms according to the basic performance and appearance of the goods. The basic forms include overlapping, crisscross, supine, seam-pressed, pagoda, ventilation, column, fish scale, cushion and shelf.

[0003] According to the patent document: CN114524389A discloses a stacker for an automated stereoscopic warehouse, comprising a mobile frame, a loading assembly is slidably arranged inside the mobile frame, a telescopic mechanism for supporting goods is arranged on the inner top of the loading assembly, the loading assembly comprises a base plate and a surrounding plate fixedly connected to the top of the base plate, the telescopic mechanism comprises a telescopic fork arranged on the top of the base plate, one end of the bottom fork of the telescopic fork is hinged to the base plate, and the other end of the bottom fork is movably connected to the base plate; the telescopic fork is retracted by a power mechanism, and the telescopic fork is still in a tilted state at this time, which is conducive to maintaining the stability of the goods during transportation and avoiding the goods from being separated from the telescopic fork, and when the front fork is retracted, the goods have slid to a position close to the middle of the telescopic fork, so the pressure applied to the front fork has been greatly reduced, thereby avoiding excessive torque on the front fork to cause damage to it.

[0004] Most stackers are basically used for stacking goods in supermarket warehouses. However, most of the existing stackers still face some challenges in stacking goods in supermarket warehouses. Although there are some automated stackers, in the process of stacking goods, especially when handling goods of different shapes, sizes and weights, such as the stacking of rice, since rice is packed in rice bags, when rice bags are transported by trucks, they are basically bundled together in the form of bundles. Generally, stackers basically lift the rice bags from the bottom by forklifts and then move them to designated locations for stacking. However, this method is easy to slip during transportation because the surface of the rice bags is relatively smooth, resulting in unstable goods and increasing the risk of goods slipping during transportation.

[0005] In addition, most stackers do not limit the lifting frame during the process of grabbing and stacking goods, which may cause the lifting frame to shift during the lifting process, resulting in inaccurate grabbing of goods, thereby affecting the stacking efficiency. Summary of the invention

[0036] When the rice bags need to be transferred from the truck to the warehouse for stacking, first, the double-axis motor 64 is started. The double-axis motor 64 drives the two conical teeth 65 to rotate. The conical teeth 65 drive the screw rod 67 to rotate through the meshing action with the second conical teeth 66. The rotation of the screw rod 67 causes the two transmission blocks 72 to move up and down along the outer wall of the screw rod 67, thereby driving the grabbing clamp connecting frame 7 to slide on the lifting frame vertical plate 62. As the grabbing clamp connecting frame 7 is lifted and lowered, the slide bar 74 slides in the lifting slide 69 until the grabbing clamp connecting frame 7 reaches a predetermined height position, so that the grabbing clamp 8 and the rice bag are at a suitable grabbing distance. At this time, the second double-axis motor 81 is started, and the third conical teeth 82 are meshed with the fourth conical teeth 83 to drive the rotating rod 84 to rotate. The rotation of the rotating rod 84 causes the gear 85 to move up and down along the lifting frame vertical plate 62. The rotation of the gear plate 86 drives the push-pull slide bar 87 to slide, and the sliding of the push-pull slide bar 87 makes the second push-pull plate 815 move to one side of the clamping plate 813. At the same time, the rotation of the gear 85 also drives the second gear plate 89 to drive the second limiting slide bar 811 to slide, so that the push-pull plate 812 moves to one side of the second push-pull plate 815. In this way, the two clamping plates 813 are pushed by the push-pull plate 812 and the second push-pull plate 815 to gradually approach and clamp the rice bag. At the same time, due to the design of the cargo grabbing clamp 814, the grabbing clamp 8141 and the side clamping plate 8144 can adaptively fit the shape of the rice bag through the action of the rotating rod 8142 and the rotating rod spring 8143 to ensure stable grabbing. The setting of the bottom support rod 8145 can support the bottom of the rice bag to prevent the rice bag from slipping during transportation.

[0037] After the grabbing clamp 8 clamps the rice bag, the double-axis motor 64 is started again, and the grabbing clamp connecting frame 7 drives the grabbing clamp 8 and the rice bag to rise through the rotation of the screw rod 67, and then moves to the other side of the transmission platform through the transmission platform 1, and then is fixedly connected to the lifting frame stand 62 through the central axis of the turntable 5. Therefore, when the central axis rotates, the entire lifting frame stand 62 and the grabbing clamp 8 and the rice bag thereon will also rotate together, and the other side of the transmission platform will transport the rice bag to the target position. During the transportation process, the slide bar 74 and the lifting slide The sliding connection of the frame 69 ensures the smooth lifting of the grabbing clamp 8. When the rice bag is transferred to the target position, the second double-axis motor 81 is started again. Through the rotation of the gear 85, the tooth plate 86 and the second tooth plate 89 are driven to respectively drive the push-pull slide bar 87 and the second limit slide bar 811 to slide in the opposite direction, so that the second push-pull plate 815 and the push-pull plate 812 are respectively separated. At this time, the grabbing clamp 8141 and the side clamp 8144 gradually loosen the rice bag under the action of the rotating rod spring 8143, completing the release of the rice bag;

[0038] During the entire transfer process, the device realizes automatic grabbing, transfer and release of rice bags through precise motor control and mechanical structure design, greatly improving work efficiency and reducing labor costs;

[0039] During the rotation process, it is necessary to ensure that the grabbing clamp 8 stably holds the rice bag to prevent the rice bag from slipping or breaking during the transportation process. At this time, the design of the cargo grabbing clamp 814 plays a key role. Its adaptive fit to the shape of the rice bag can ensure stability during the rotation process;

[0040] In addition, in order to ensure the stability and safety of the transfer process, the entire transfer device is also equipped with necessary sensors and safety protection devices. For example, by installing pressure sensors on the grabbing clamp 8 and the cargo grabbing clamp 814, the grabbing force can be monitored in real time to prevent the rice bags from being excessively squeezed or damaged during the transfer process. At the same time, the transfer device is also equipped with an emergency stop button and an alarm device. Once an abnormal situation occurs, the transfer can be stopped immediately and an alarm can be sounded to ensure the safety of the operator.

[0041] like Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Fig.10As shown, the transmission platform 1 includes a transmission platform bottom plate 11, and the left and right sides of the top of the transmission platform bottom plate 11 are respectively fixedly connected with an I-shaped frame 12, the tops of the two I-shaped frames 12 are fixedly connected with a slide plate 13, the tops of the two slide plates 13 are slidably connected with a moving plate 14, the opposite sides of the two moving plates 14 are fixedly connected with a lifting frame connecting plate 15, the opposite sides of the two slide plates 13 are fixedly connected with a rack 16, the opposite sides of the two lifting frame connecting plates 15 are fixedly connected with a transmission gear motor 17, the output ends of the two transmission gear motors 17 are fixedly connected with a transmission platform gear 18, and the outer walls of the two transmission platform gears 18 are meshed with the opposite sides of the rack 16, and the four limiting frames 2 include a limiting frame vertical plate 21, and the opposite sides of the four limiting frame vertical plates 21 are fixedly connected with a U-shaped connecting frame 22, and the opposite sides of the four U-shaped connecting frames 22 are respectively fixedly connected to the front and rear sides of the left and right sides of the transmission platform bottom plate 11. One side of the positioning frame upright plate 21 is provided with a limiting groove 23 that penetrates to both sides of the limiting frame upright plate 21. The two limiting plates 9 include a limiting plate bottom plate 91. The opposite surfaces of the two limiting plate bottom plates 91 are respectively fixedly connected to the left and right sides of the lifting frame bottom plate 61. The top of the two limiting plate bottom plates 91 is fixedly connected to the limiting plate upright plate 92 on one side away from the lifting frame bottom plate 61. The inner walls of the two limiting plate upright plates 92 are slidably connected with a clamping rod 93. The opposite surfaces of the two clamping rods 93 are fixedly connected with an inclined plate 94. The opposite surfaces of the two inclined plates 94 are respectively fixedly connected with two inclined plate sliding rods 95. The opposite surfaces of the two clamping rods 93 respectively penetrate the opposite surfaces of the two limiting plate upright plates 92 and the outer walls are fixedly connected with spring connecting blocks 96. The two clamping rods 93 penetrate the outer walls of the opposite surfaces of the two limiting plate upright plates 92 and are covered with springs 97. The opposite ends of the two springs 97 are respectively fixedly connected to the opposite surfaces of the two spring connecting blocks 96.

[0042] When grabbing the rice bag, the setting of the limit frame 2 further enhances the stability during the grabbing process. When the grabbing clamp connecting frame 7 drives the grabbing clamp 8 to move downward, it drives the reverse inclined plate 75 to move downward and drives the reverse inclined plate 75 and the opened reverse inclined plate slide groove 76 and the inclined plate 94 to overlap with the inclined plate slide rod 95, so that the inclined plate 94 drives the inclined plate slide rod 95 to move toward the inside of the limit plate vertical plate 92 under the push of the reverse inclined plate 75. At the same time, the inclined plate 94 drives the clamping rod 93 to move toward the inside of the limit plate vertical plate 92, and stretches the spring 97, so that the clamping rod 93 moves to the inside of the limit groove 23 to limit the lifting frame 6. The anti-grabbing clamp 8 shakes or deflects during the grabbing process, which ensures the stability of the rice bag when grabbing. After the rice bag is grabbed, when the grabbing clamp connecting frame 7 is raised, the anti-inclined plate 75 will move upward with the grabbing clamp connecting frame 7, thereby breaking away from the overlapping state with the inclined plate 94 and the inclined plate slide bar 95. At this time, under the pulling force of the spring 97, the clamping rod 93 will slide outward along the inside of the limit plate vertical plate 92, and finally return to the initial position, thereby releasing the limit on the lifting frame 6. This design not only ensures the stability during the grabbing process, but also ensures the flexibility during the transportation process, making the entire transportation process smoother and more efficient.

[0043] When it is necessary to move the lifting frame 6 to the other side of the transmission platform, the transmission gear motor 17 is started to drive the transmission platform gear 18 to rotate. Due to the meshing action of the transmission platform gear 18 and the rack 16, the moving plate 14 moves to the other side of the transmission platform on the slide plate 13, and at the same time drives the lifting frame 6 and the grabbing clamp 8 to move together. When moving to the target position, the transmission gear motor 17 stops working. At this time, the lifting frame 6, the grabbing clamp 8 and the rice bag have all been accurately moved to the target position, ready for the subsequent stacking operation.

[0044] Working principle of the present invention: when it is necessary to transfer the rice bags from the truck to the warehouse for stacking, first, start the double-axis motor 64, the double-axis motor 64 drives the two conical teeth 65 to rotate, the conical teeth 65 drive the screw rod 67 to rotate through the meshing action with the second conical teeth 66, the rotation of the screw rod 67 makes the two transmission blocks 72 move up and down along the outer wall of the screw rod 67, thereby driving the grabbing clamp connecting frame 7 to slide on the lifting frame vertical plate 62, with the lifting and lowering of the grabbing clamp connecting frame 7, the slide bar 74 slides in the lifting slide 69 until the grabbing clamp connecting frame 7 reaches a predetermined height position, so that the grabbing clamp 8 and the rice bag are at a suitable grabbing distance, at this time, the second The double-axis motor 81 is started, and the third conical tooth 82 is meshed with the fourth conical tooth 83 to drive the rotating rod 84 to rotate. The rotation of the rotating rod 84 causes the gear 85 to rotate accordingly, thereby driving the tooth plate 86 to drive the push-pull slide bar 87 to slide. The sliding of the push-pull slide bar 87 causes the second push-pull plate 815 to move toward one side of the clamping plate 813. At the same time, the rotation of the gear 85 also drives the second tooth plate 89 to drive the second limiting slide bar 811 to slide, so that the push-pull plate 812 moves toward one side of the second push-pull plate 815. In this way, the two clamping plates 813 are pushed by the push-pull plates 812 and the second push-pull plates 815 to gradually approach and clamp the rice bag. At the same time, due to the cargo grasping The design of the grabbing clamp 814, the grabbing clamp plate 8141 and the side clamp plate 8144 can adaptively fit the shape of the rice bag through the action of the rotating rod 8142 and the rotating rod spring 8143 to ensure stable grabbing, and the setting of the bottom support rod 8145 can support the bottom of the rice bag to prevent the rice bag from slipping during transportation. After the grabbing clamp 8 clamps the rice bag, the double-axis motor 64 is started again, and the grabbing clamp connecting frame 7 drives the grabbing clamp 8 and the rice bag to rise through the rotation of the screw rod 67, and then moves to the other side of the transmission platform 1 through the transmission platform, and then is fixedly connected to the lifting frame upright plate 62 through the central axis of the turntable 5. Therefore, when the central axis rotates, the entire lifting frame upright plate 62 and The grabbing clamp 8 and the rice bag thereon will also rotate together, and the other side of the transmission platform will transport the rice bag to the target position. During the transportation process, the sliding connection between the slide bar 74 and the lifting slide 69 ensures the smooth lifting of the grabbing clamp 8. When the rice bag is transported to the target position, the second double-axis motor 81 is started again, and the gear plate 86 and the second gear plate 89 are driven to respectively drive the push-pull slide bar 87 and the second limit slide bar 811 to slide in the opposite direction through the rotation of the gear 85, so that the second push-pull plate 815 and the push-pull plate 812 are respectively separated. At this time, the grabbing clamp plate 8141 and the side clamp plate 8144 gradually loosen the rice bag under the action of the rotating rod spring 8143, and the rice bag is released;

[0045] When the bag is grabbed, the setting of the limit frame 2 further enhances the stability of the grabbing process. When the grabbing clamp connecting frame 7 drives the grabbing clamp 8 to move downward, it drives the reverse inclined plate 75 to move downward and drives the reverse inclined plate 75 and the reverse inclined plate slide groove 76 and the inclined plate 94 to overlap with the inclined plate slide bar 95, so that the inclined plate 94 drives the inclined plate slide bar 95 to move toward the inside of the limit plate vertical plate 92 under the push of the reverse inclined plate 75. At the same time, the inclined plate 94 drives the clamping rod 93 to move toward the inside of the limit plate vertical plate 92 and stretch the spring 97. The clamping rod 93 moves to the inside of the limit groove 23 to limit the lifting frame 6, preventing the grabbing clamp 8 from shaking or deflecting during the grabbing process, thereby ensuring the stability of the bag when grabbing. After the bag is grabbed, when the grabbing clamp connecting frame 7 is raised, the reverse inclined plate 75 will move upward with the grabbing clamp connecting frame 7, thereby disengaging from the inclined plate 94 and the inclined plate slide When the lifting frame 6 is in the overlapped state, the rod 95 is in the overlapped state. At this time, under the pulling force of the spring 97, the card rod 93 will slide outward along the inside of the limit plate vertical plate 92, and finally return to the initial position, thereby releasing the limit on the lifting frame 6. This design not only ensures the stability during the grabbing process, but also ensures the flexibility during the transportation process, making the entire transportation process smoother and more efficient. When it is necessary to move the lifting frame 6 to the other side of the transmission platform, the transmission gear motor 17 is started to drive the transmission platform gear 18 to rotate. Due to the meshing action of the transmission platform gear 18 and the rack 16, the moving plate 14 moves to the other side of the transmission platform on the slide plate 13, and at the same time drives the lifting frame 6 and the grabbing clamp 8 to move together. When moving to the target position, the transmission gear motor 17 stops working. At this time, the lifting frame 6, the grabbing clamp 8 and the rice bag have all been accurately moved to the target position, ready for the subsequent stacking operation.
