Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to an automated warehouse standard stacker crane. Background Technology

[0002] In the field of automated warehousing, stacker cranes, as standardized goods storage and retrieval equipment, are used in chain retail central warehouses, conventional e-commerce warehouses, and general raw material warehouses in the manufacturing industry due to their advantages of fixed parameters, efficient deployment, and adaptability to general warehousing scenarios. Their core function is to complete the lifting, horizontal movement, and rack storage and retrieval operations of goods along preset tracks to achieve automation and efficiency in the warehousing process.

[0003] Currently, mainstream automated warehouse stacker cranes are designed for standardized goods, and their racking structure is an L-shaped clamp-arm structure. During operation, the clamps support the bottom of the goods, and together with the lifting mechanism and the track running mechanism, the goods are transferred between different racking levels. However, because the top of the racking of existing stacker cranes is generally open, when the stacker crane's transfer height is high, the center of gravity of the goods shifts, or there is slight vibration during operation, the limited bottom support is insufficient to effectively restrain the goods, and the goods are prone to longitudinal movement or lateral slippage. Therefore, there is a need to design an automated warehouse stacker crane.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides an automated warehouse stacker crane to solve the problem that when using an L-shaped clamp arm to support the bottom of goods for transfer, the goods are prone to shifting and sliding during high-speed transfers, when the center of gravity is off-center, or when there is vibration.

[0006] This utility model embodiment adopts the following technical solution: an automated warehouse stacker crane. It mainly includes a support unit, which includes two sets of mounting frames. A connecting frame is fixedly connected between the two sets of mounting frames. A mounting plate is fixed on the connecting frame. A lifting unit is provided on the mounting plate. The lifting unit includes a support frame fixed on the mounting plate. A lead screw is bearing-connected between the support frame and the connecting frame. A mounting back plate is threaded onto the lead screw. A clamping assembly is provided on the lifting unit. The clamping assembly includes two sets of fixed parts fixed on the lifting unit and used to provide a mounting base and movement space. The fixed parts are provided with clamping parts for providing an adjustable support base for clamping goods. The clamping parts are provided with folding parts for clamping goods on both sides. The lifting unit is provided with a transmission part for adjusting the position of the folding parts to adapt to the clamping requirements of goods of different sizes.

[0007] Furthermore, the fixing part includes mounting boxes fixed to both sides of the mounting back plate. Each mounting box has an opening. A bidirectional lead screw is movably arranged between the two sets of mounting boxes. The bidirectional lead screw has two sets of threaded grooves with opposite directions of rotation. The two sets of threaded grooves are respectively located in the two sets of mounting boxes. The two ends of the bidirectional lead screw are movably connected to the ends farther from the inner walls of the two sets of mounting boxes. The bidirectional lead screw movably passes through the support frame and the mounting back plate. The support frame has waist grooves on both sides for the bidirectional lead screw to move.

[0008] Furthermore, the clamping part includes a sliding seat threadedly connected to two sets of threaded grooves on the bidirectional lead screw, an L-shaped auxiliary plate fixed to the side of the sliding seat, a guide rail fixed to the upper surface of the mounting box, and a slider adapted to slide on the guide rail fixed to the bottom surface of the horizontal end of the auxiliary plate.

[0009] Furthermore, the folding part includes a concave frame fixed to the vertical end of the auxiliary plate. A second motor is fixed on the concave frame. The output end of the second motor passes through the concave frame and is fixed with a rotating shaft. One end of the rotating shaft is connected to a bearing on the bottom surface of the inner wall of the concave frame. A concave structure mounting cover is fixedly sleeved on the rotating shaft. The upper and lower surfaces of the mounting cover are in contact with the upper and lower surfaces of the inner wall of the concave frame. A horizontally arranged connecting shaft is connected to a bearing on the mounting cover. One end of the connecting shaft has a second bevel gear. A first bevel gear that meshes with the second bevel gear is fixedly sleeved on the rotating shaft. A fixing block is fixed to one end of the connecting shaft, and a clamping arm is fixed to one end of the fixing block.

[0010] Furthermore, a pressure sensor is embedded on the side of the clamping arm closest to the cargo.

[0011] Furthermore, the transmission unit includes a motor three fixedly mounted on the back of the mounting plate, a bevel gear four fixedly mounted on the output end of the motor three, and a bevel gear three fixedly mounted on the bidirectional lead screw that meshes with the bevel gear four.

[0012] Furthermore, the mounting plate is equipped with control devices.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: An automated warehouse stacker crane provides a foundation through a support unit and utilizes a screw drive in the lifting unit to smoothly raise and lower the mounting backplate and goods. Simultaneously, the fixing part in the clamping assembly provides installation and movement space for related components. The clamping part provides stable support for goods clamping through an adjustable structure, and the stacking part can effectively clamp goods from both sides. Combined with the transmission unit, the clamping position can be adjusted according to the size of the goods, solving the problems of existing stacker cranes that only have bottom support and are prone to longitudinal movement or lateral slippage of goods. The overall structure, through the combination of bottom support and side clamping, can restrain the goods when the transfer height is high, the center of gravity of the goods shifts, or there is vibration during operation.

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-2 and Figure 4 As shown in the figure, an automated warehouse stacker crane provided by this utility model includes a stacker crane 1. The stacker crane 1 includes a support part, and the support part includes two sets of mounting frames 11. A connecting frame 13 is connected and fixed between the two sets of mounting frames 11. A caster wheel 12 is provided at one end of the two sets of mounting frames 11. A caster wheel 15 is fixed on the bottom surface of the connecting frame 13, so as to enable the stacker crane 1 to move flexibly in the warehouse aisle and facilitate the staff to transfer the stacker crane 1 to different goods storage areas. A mounting plate 14 is fixed to the connecting frame 13, and a control device 16 is provided on the mounting plate 14. In actual operation, the operation of the stacker crane 1 is controlled by the control device 16, such as controlling the lifting, moving and other actions of the stacker crane 1, which is very convenient. A lifting part is provided on the mounting plate 14, which includes a support frame 141 fixed on the mounting plate 14. The support frame 141 has an inner groove, and a lead screw 17 is bearing-connected between the support frame 141 and the connecting frame 13. 7 is threadedly connected to a mounting back plate 110. Two sets of support arms 111 with spacing are fixed on the mounting back plate 110. The support arms 111 are used to support the goods. Sliding plates 113 are fixed on both sides of the mounting back plate 110. Pulleys 114 are provided on the side of the sliding plate 113 near the inner wall of the support frame 141. At the same time, guide grooves (not shown in the figure) are provided on both sides of the inner wall of the support frame 141 for the pulleys 114 to slide vertically, so as to make the mounting back plate 110 more stable during the lifting process. A drive unit is provided on the connecting frame 13. The drive unit includes a motor (not shown in the figure) fixed on the mounting plate 14 and located inside the housing of the control device 16. In actual operation, the motor provides power, and a gear part 18 is fixed at the output end of the motor. At the same time, a gear part 19 that meshes with the gear part 18 is fixedly sleeved on the lead screw 17. Through the meshing transmission of the gears, the power of the motor is transmitted to the lead screw 17, which drives the lead screw 17 to rotate, thereby realizing the lifting and lowering of the mounting back plate 110. A handle 112 is provided on the mounting plate 14, which can be held by the operator to push the stacker crane 1, making the operation more labor-saving.

[0020] like Figures 4-7 As shown, in warehousing operations, to better handle goods and prevent them from falling during lifting or movement, a clamping assembly 2 is provided on the mounting back plate 110. The clamping assembly 2 includes two sets of fixing parts, each consisting of a mounting box 21 fixed to both sides of the mounting back plate 110. Each mounting box 21 has an opening, and a bidirectional lead screw 22 is movably arranged between the two sets of mounting boxes 21. The bidirectional lead screw 22 has two sets of threaded grooves with opposite directions of rotation, which are located inside the two sets of mounting boxes 21. Both ends of the bidirectional lead screw 22 are movably connected to the ends furthest from the inner walls of the two sets of mounting boxes 21, ensuring that the bidirectional lead screw 22 can rotate stably. The bidirectional lead screw 22 is movably inserted through the support frame 141 and the mounting back plate 110. At the same time, waist grooves (not shown in the figure) are provided on both sides of the support frame 141 for the bidirectional lead screw 22 to move, so that the bidirectional lead screw 22 has room to move when it is lifted and lowered with the mounting back plate 110.

[0021] Furthermore, clamping parts are connected to both sets of threaded grooves on the bidirectional lead screw 22. Each clamping part includes a sliding seat 23 threadedly connected to the two sets of threaded grooves on the bidirectional lead screw 22. When the bidirectional lead screw 22 rotates, the sliding seat 23 moves linearly along the opening of the mounting box 21 through the threaded grooves. An L-shaped auxiliary plate 24 is fixed to the side of the sliding seat 23. At the same time, a guide rail 214 is fixed to the upper surface of the mounting box 21. A slider 213 adapted to slide with the guide rail 214 is fixed to the bottom surface of the horizontal end of the auxiliary plate 24. Through the cooperation of the guide rail 214 and the slider 213, the auxiliary plate 24 can move more smoothly and steadily. A folding section is provided on the auxiliary plate 24. This folding section includes a concave frame 25 fixed to the vertical end of the auxiliary plate 24, and a second motor 212 is fixed on the concave frame 25. The output end of the second motor 212 passes through the concave frame 25 and is fixed with a rotating shaft 26. One end of the rotating shaft 26 is connected to a bearing on the bottom surface of the inner wall of the concave frame 25 to ensure stable rotation of the rotating shaft 26. A concave structure mounting cover 28 is fixedly sleeved on the rotating shaft 26. The upper and lower surfaces of the mounting cover 28 are in contact with the upper and lower surfaces of the inner wall of the concave frame 25. A horizontally arranged connecting shaft 210 is connected to the mounting cover 28 with a bearing. One end of the connecting shaft 210 has a second bevel gear 29. A first bevel gear 27 that meshes with the second bevel gear 29 is fixedly sleeved on the rotating shaft 26. Through the meshing transmission of the bevel gears, the power of the second motor 212 can be transmitted to realize the rotation of the connecting shaft 210.

[0022] A fixing block 211 is fixed at one end of the connecting shaft 210, and a clamping arm 215 is fixed at one end of the fixing block 211. In actual use, the folding part can fold or unfold the clamping arm 215, and the clamping arm 215 is suitable for contacting the two sides of the goods to clamp them. A pressure sensor is embedded on the side of the clamping arm 215 near the goods. The pressure sensor is used to detect the clamping force of the clamping arm 215 on the goods. This can avoid the goods being damaged by excessive clamping force or the goods falling off due to insufficient clamping force. The clamping force can be controlled by the control device 16 based on the feedback from the pressure sensor.

[0023] Meanwhile, a transmission unit is provided on the back of the mounting back plate 110. The transmission unit includes a motor 216 fixedly mounted on the back of the mounting back plate 110. A bevel gear 218 is fixed to the output end of the motor 216. A bevel gear 217 that meshes with the bevel gear 218 is fixed on the bidirectional lead screw 22. When the motor 216 is running, the meshing of the bevel gear 217 and the bevel gear 218 drives the bidirectional lead screw 22 to rotate, thereby moving the sliding seat 23 and adjusting the position of the clamping arm 215 to accommodate goods of different sizes.

[0024] It should be noted that in actual use, the folding part is activated first, so that the clamping arm 215 rotates 90 degrees counterclockwise along the axis of the connecting shaft 210. Simultaneously, the clamping arm 215 rotates 90 degrees counterclockwise along the axis of the rotating shaft 26 via the mounting cover 28. At this time, the two sets of clamping arms 215 are on both sides of the support arm 111 and are parallel to each other. This folding method can fold up the clamping arm 215 when it is not necessary to clamp the goods, without affecting other operations such as the support arm 111 lifting the goods.

[0025] Working Principle: When using the stacker crane 1 for cargo handling, the operator first holds the handle 112 and, with the help of casters 12 and 15, moves the stacker crane 1 flexibly to the location of the cargo to be handled in the warehouse. If the cargo is placed at a suitable height for the support arm 111 to lift, it can be directly supported by inserting the support arm 111 into the bottom of the cargo. If the cargo height is not suitable, the motor 1 of the drive unit can be started. The output end of the motor 1 drives the gear part 18 to rotate. The gear part 18 meshes with the gear part 19 on the lead screw 17, thereby driving the lead screw 17 to rotate. When the lead screw 17 rotates, the mounting back plate 110, which is threadedly connected to the lead screw 17, moves vertically along the guide grooves on both sides of the inner wall of the support frame 141. The pulleys 114 on the sliding plates 113 on both sides of the mounting back plate 110 slide in the guide grooves, ensuring that the mounting back plate 110 rises and falls smoothly, thereby adjusting the height of the support arm 111 so that it can be smoothly inserted into the bottom of the cargo to support it. If clamping operations are required, first start motor 212 in the stacking section. After motor 212 starts running, its output end drives the rotating shaft 26 to rotate, and the bevel gear 27 on the rotating shaft 26 rotates accordingly. Since bevel gear 27 meshes with bevel gear 29 at one end of the connecting shaft 210, bevel gear 29 will drive the connecting shaft 210 to rotate, thereby causing the clamping arm 215 to rotate 90 degrees counterclockwise along the axial direction of the connecting shaft 210. At the same time, the rotation of the rotating shaft 26 will also drive the mounting cover 28 to rotate, and the clamping arm 215 will rotate 90 degrees counterclockwise along the axial direction of the rotating shaft 26 through the mounting cover 28. Finally, the two sets of clamping arms 215 unfold to both sides of the support arm 111 and are parallel to each other, preparing for subsequent clamping of goods.

[0026] Next, the motor 3 216 of the transmission unit is started. The output end of the motor 3 216 drives the bevel gear 4 218 to rotate. The bevel gear 4 218 meshes with the bevel gear 3 217 on the double-acting lead screw 22, thereby driving the double-acting lead screw 22 to rotate. Since the double-acting lead screw 22 has two sets of threaded grooves with opposite directions of rotation, the sliding seat 23 threadedly connected to the threaded groove will move in opposite directions along the opening of the mounting box 21, thereby driving the clamping arm 215 to move through the auxiliary plate 24, adjusting the distance between the two sets of clamping arms 215 to adapt to the width of the goods. During the clamping process, the pressure sensor on the side of the clamping arm 215 near the goods will detect the clamping force in real time and feed the signal back to the control device 16. The control device 16 controls the operation of the motor 3 216 according to the feedback signal to control the clamping force, avoiding excessive clamping force that damages the goods or insufficient clamping force that causes the goods to fall.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
