Description

Technical Field

[0001] This application relates to the field of logistics warehousing technology, and particularly to a three-dimensional warehouse for storing chemical fibers. Background Art

[0002] Chemical fiber materials are raw materials for fabrics. Before the production and sale of chemical fiber materials, it is necessary to pack and store the chemical fiber materials, and the warehousing of chemical fiber materials requires a large amount of space. An automated three-dimensional warehouse is a new warehousing facility. Using three-dimensional warehouse equipment, the rationalization of the high-rise of the warehouse, the automation of storage and retrieval, and the simplicity of operation can be realized; the main body of the automated three-dimensional warehouse consists of shelves, aisle stackers, inbound (outbound) workbenches, and automatic in (out) and operation control systems. The aisle stacker travels through the aisles between the shelves to complete the work of storing and retrieving goods.

[0003] In order to make full use of the warehousing space, there are three-dimensional warehouses with double-depth positions in the prior art. The double-depth three-dimensional warehouse can enable the stacker to stack two pieces of goods in the same direction, increasing the number of goods that each stacker can stack. However, when the stacker stacks the goods outside the stacker aisle, the extended arm length needs to be doubled, which greatly increases the working load of the stacker and increases the failure rate of the stacker. Summary of the Invention

[0004] In order to reduce the working load of the stacker for double-depth transportation in the three-dimensional warehouse for storing chemical fibers, this application provides a three-dimensional warehouse for storing chemical fibers.

[0005] A three-dimensional warehouse for storing chemical fibers provided by this application adopts the following technical solutions:

[0006] A three-dimensional warehouse for storing chemical fibers includes three-dimensional shelves and a stacker. The three-dimensional shelves are grouped in pairs, and an aisle for the stacker to move is formed between two three-dimensional shelves in the same group; the stacker includes a horizontal track device, a lifting frame device, and a cargo conveying device. The horizontal track device is used to drive the lifting frame device to move horizontally longitudinally in the aisle. The lifting frame device is used to drive the cargo conveying device to move up and down. The cargo conveying device is used to load goods and convey the goods to the storage positions of the three-dimensional shelves; the cargo conveying device includes a mounting frame, a bearing member, and a lateral driving mechanism. The lateral driving mechanism is installed on the mounting frame, and the bearing member is installed above the lateral driving mechanism; the three-dimensional shelves are arranged in a double-storage structure horizontally. In the double-storage positions of the three-dimensional shelves, the storage position close to the aisle is the inner storage position, and the storage position far from the aisle is the outer storage position. The outer storage position is higher than the inner storage position; when the cargo conveying device conveys goods to the inner storage position, the inner storage position can support the lateral driving mechanism.

[0007] By adopting the above technical solution, when the cargo conveying device conveys goods, the goods are loaded by the bearing member, and the bearing member is driven by the lateral driving mechanism to move laterally, so that the bearing member moves the goods to the corresponding storage position. When the bearing member conveys goods to the outer storage position, the lateral driving mechanism moves above the inner storage position, and the inner storage position is used to support the lateral driving mechanism, so that part of the gravity of the goods acts on the inner storage position through the lateral driving mechanism, which is beneficial to reducing the load borne by the lateral driving mechanism and reducing the failure rate of the cargo conveying device. When the lateral driving mechanism abuts against the inner storage position, it is beneficial to shorten the lever arm of the gravity of the goods, thereby reducing the load on the bearing member.

[0008] Optionally, both the outer storage position and the inner storage position have a plurality of mutually parallel cross beams for supporting the goods, and the space between two adjacent cross beams can accommodate the bearing member.

[0009] By adopting the above technical solution, when the bearing member places the goods on the outer storage position, the two cross beams of the outer storage position support the goods. At this time, the space between the two cross beams can accommodate the bearing member, enabling the bearing member to directly withdraw horizontally from the outer storage position.

[0010] Optionally, the mounting frame is provided with an auxiliary support mechanism, and the auxiliary support mechanism includes a sliding seat, a vertical telescopic member and a lateral translation driving member. The sliding seat is slidably connected to the mounting frame in the lateral direction. The vertical telescopic member is installed on the sliding seat, and the vertical support member is used to abut against the cross beam of the inner storage position.

[0011] By adopting the above technical solution, the vertical telescopic member of the auxiliary support mechanism can move onto the cross beam of the inner storage position under the drive of the lateral translation driving member. When the vertical telescopic member abuts against the cross beam, the weight of the goods can act on the inner storage position indirectly through the auxiliary support mechanism.

[0012] Optionally, the vertical telescopic member is provided with rollers, and the auxiliary support mechanism abuts against the lateral driving mechanism through the rollers.

[0013] By adopting the above technical solution, by providing rollers on the vertical telescopic member, the resistance of the auxiliary support mechanism moving on the cross beam can be reduced.

[0014] Optionally, the rollers are roller wheels, the axis of the roller wheels is along the longitudinal direction, a plurality of roller wheels are provided, and at least two roller wheels are arranged side by side in the lateral direction.

[0015] By adopting the above technical solution, two roller wheels are arranged side by side in the lateral direction, which can increase the contact range between the auxiliary support mechanism and the cross beam, thereby reducing the situation that the auxiliary support mechanism swings under the action of the moving resistance between it and the cross beam.

[0016] Optionally, a roller seat for installing the roller is provided at the lower end of the vertical telescopic member, and the roller seat can be used to support the carrier member.

[0017] By adopting the above technical solution, when the cargo conveying device conveys goods to the outer storage position of the stereoscopic shelf, first move the roller of the auxiliary support mechanism to the inner storage position, and then drive the carrier member to move outward to the outer storage position by the lateral drive mechanism. During this process, the carrier member passes over the roller of the auxiliary support mechanism and is supported by the roller, so that part of the gravity of the goods acts on the inner storage position through the roller.

[0018] Optionally, the lateral drive mechanism is provided with a distance sensor for detecting the inner storage position.

[0019] By adopting the above technical solution, when the lifting frame device drives the cargo conveying device to move downward so that the lateral drive mechanism abuts against the inner working position, the distance sensor is used to sense the distance between the lateral drive mechanism and the inner storage position, and the lateral drive mechanism moves at a reduced speed when it is about to abut against the inner working position, so as to reduce the impact between the lateral drive mechanism and the inner working position.

[0020] Optionally, the cargo conveying device further includes a suspension traction mechanism, which includes a stay cable and a fixed pulley. The fixed pulley is installed on the side of the mounting frame. One end of the stay cable is fixedly connected to the front end of the carrier member, and the other end of the stay cable is inclined upward and bypasses the fixed pulley to be connected to the mounting frame. A plurality of tension springs with different specifications are sleeved on the stay cable, and both ends of the tension spring are fixedly connected to the stay cable respectively. The part of the stay cable located inside the tension spring forms a buffer section with a zigzag extension, and the length of the buffer section in the straight state is less than the limit tensile size of the tension spring.

[0021] By adopting the above technical solution, when the cargo conveying device conveys goods, the carrier member moves under the driving action of the lateral drive mechanism. When the carrier member moves, the stay cable is subjected to a tensile force, causing the tension springs on the stay cable to undergo tensile deformation and the stay cable to elongate. During the elongation of the stay cable, each tension spring reaches the maximum tensile deformation amount in sequence according to different elastic moduli, and at the same time, the tensile force of the stay cable gradually increases to adapt to the change in the magnitude of the moment of the carrier member.

[0022] Optionally, the cargo conveying device can reach the three-dimensional shelves on both sides of the roadway within the range of the lateral movement stroke; there are two sets of the hanging traction mechanisms, and the two sets of the hanging traction mechanisms respectively correspond to the two ends of the bearing member along the transverse direction; the stay cable is detachably connected to the mounting frame through a hook assembly, the hook assembly includes a hook seat and a hook, the hook is connected to the stay cable, the hook seat is connected to the mounting frame, a magnet is embedded at the end of the hook, and the hook seat is provided with a hook slot for the hook to be hooked; a compression spring is arranged in the hook slot, and the compression spring is used to prevent the end of the hook from entering the hook slot, and the hook seat is provided with an electromagnet, and the magnetic attraction force between the electromagnet and the magnet can force the end of the hook to overcome the elastic force of the compression spring and enter the hook slot.

[0023] By adopting the above technical solution, when the cargo conveying device moves in the opposite direction of the lateral movement stroke, it can convey goods to different shelves. When the cargo conveying device conveys goods to the shelves on one side, the stay cable of one set of the hanging traction mechanisms is connected to the mounting frame through the hook assembly, and the hook assemblies of the other set of the hanging traction mechanisms remain in the unhooked state. When the hook assembly functions, the electromagnet is energized, so that the hook is hooked into the hook slot under the action of the magnetic attraction force between the magnet and the electromagnet. When the electromagnet is powered off, the hook is disengaged from the hook slot under the action of the compression spring, so that the hook assembly is in the unhooked state.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] When the cargo conveying device conveys goods, the lateral driving mechanism moves above the inner storage position, and the inner storage position is used to support the lateral driving mechanism, so that part of the gravity of the goods acts on the inner storage position through the lateral driving mechanism, which is beneficial to reducing the load borne by the lateral driving mechanism and reducing the failure rate of the cargo conveying device. When the lateral driving mechanism abuts against the inner storage position, it is beneficial to shorten the lever arm of the gravity of the goods, thereby reducing the load of the bearing member.

[0026] When the cargo conveying device conveys goods, the bearing member moves under the driving action of the lateral driving mechanism. When the bearing member moves, the stay cable is subjected to a tensile force, causing the tension spring on the stay cable to undergo tensile deformation, so that the stay cable elongates. During the elongation process of the stay cable, each tension spring reaches the maximum tensile deformation amount in sequence according to different elastic moduli, and at the same time, the tension of the stay cable gradually increases to adapt to the change in the magnitude of the moment of the bearing member.

Detailed implementation manners

[0036] The following further elaborates on this application in conjunction with the attached Figures 1 - 7 drawings for a more detailed description. Example 1

[0037] This application example discloses a chemical fiber storage three-dimensional warehouse. Refer to Figure 1 and Figure 2, the chemical fiber storage stereoscopic warehouse includes a stereoscopic shelf 1 and a stacker crane 2. The stereoscopic shelves 1 are grouped in pairs, and a lane 3 for the movement of the stacker crane 2 is formed between two stereoscopic shelves 1 in the same group; the stacker crane 2 includes a horizontal track device 21, a lifting frame device 22 and a cargo conveying device 23. The horizontal track device 21 is used to drive the lifting frame device 22 to move horizontally along the depth direction of the lane 3. The depth direction of the lane 3 is the longitudinal direction. The lifting frame device 22 is used to drive the cargo conveying device 23 to move up and down. The cargo conveying device 23 is used to load goods and convey the goods to the storage positions of the stereoscopic shelf 1. The cargo conveying device 23 can reach the stereoscopic shelves 1 on both sides of the lane 3 within the range of the lateral movement stroke.

[0038] Refer to Figure 1 , the stereoscopic shelf 1 is arranged in a double storage position structure along the transverse direction. Among the double storage positions of the stereoscopic shelf 1, the storage position close to the lane 3 is the inner storage position 11, and the storage position far from the lane 3 is the outer storage position 12. The outer storage position 12 is higher than the inner storage position 11. The outer storage position 12 has at least two cross beams 13. The cross beams 13 are used to support goods, and there is a height difference between adjacent cross beams 13 that can accommodate the carrier 233. The structure of the inner storage position 11 is the same as that of the outer storage position 12. When the goods are placed in the inner storage position 11 or the outer storage position 12, the two cross beams 13 support the goods. At this time, the carrier 233 can directly withdraw from the storage position where the goods are located without relying on a pallet.

[0039] Refer to Figure 2 , the cargo conveying device 23 includes a mounting frame 231, a lateral driving mechanism 232 and a carrier 233. The lateral driving mechanism 232 is mounted on the mounting frame 231, and the carrier 233 is mounted above the lateral driving mechanism 232. The carrier 233 in this embodiment is a horizontally arranged table board. In another embodiment, the carrier 233 can be replaced with a fork structure; when the cargo conveying device 23 conveys goods to the inner storage position 11, the inner storage position 11 can support the lateral driving mechanism 232. The lateral driving mechanism 232 is a combined driving mechanism of a motor combined with a gear-rack assembly group or a synchronous belt assembly.

[0040] The number of the cross beams 13 is set according to the structure of the carrier 233. When the carrier 233 is a table board structure, two cross beams 13 are provided. When the carrier 233 is a fork structure, the number of the cross beams 13 is set to three. The spaces between the three cross beams 13 can respectively accommodate the two fork arms of the fork.

[0041] A distance sensor is provided on the downward side of the lateral driving mechanism 232. The distance sensor is used to detect the inner storage position 11. The distance sensor senses the distance between the lateral driving mechanism 232 and the inner storage position 11, so that the lateral driving mechanism 232 decelerates when it is about to abut against the inner working position, so as to reduce the impact between the lateral driving mechanism 232 and the inner working position.

[0042] The implementation principle of a three-dimensional chemical fiber storage warehouse in an embodiment of the present application is as follows: When the cargo conveying device 23 conveys goods, the goods are loaded by the bearing member 233, and the bearing member 233 is driven by the lateral driving mechanism 232 to move laterally, so that the bearing member 233 moves the goods to the corresponding storage positions. When the bearing member 233 conveys goods to the outer storage position 12, the lateral driving mechanism 232 moves above the inner storage position 11, and the inner storage position 11 is used to support the lateral driving mechanism 232, so that part of the gravity of the goods acts on the inner storage position 11 through the lateral driving mechanism 232, which is beneficial to reducing the load on the lateral driving mechanism 232 and reducing the failure rate of the cargo conveying device 23. When the lateral driving mechanism 232 abuts against the inner storage position 11, it is beneficial to shorten the lever arm of the gravity of the goods, thereby reducing the load on the bearing member 233. After the goods are transported laterally to the position, the lateral driving mechanism 232 is then moved longitudinally, so that the lateral driving mechanism 232 leaves the cross beam 13 of the inner storage position 11, so that the lateral driving mechanism 232 and the bearing member 233 can move downward a short distance to unload the goods. Embodiment 2

[0043] Refer to Figure 3 and Figure 4 In this embodiment, the difference from Embodiment 1 is that the mounting frame 231 is provided with an auxiliary support mechanism 5. The auxiliary support mechanism 5 is located above the bearing member 233. There are two groups of the auxiliary support mechanism 5, and the two groups of the auxiliary support mechanism 5 are respectively located at both longitudinal ends of the mounting frame 231. Each group of the auxiliary support mechanism 5 has two, and the two in the same group of the auxiliary support mechanism 5 are symmetrically arranged. The two in the same group of the auxiliary support mechanism 5 are respectively located on both sides of the bearing member 233, that is, the four auxiliary support mechanisms 5 are distributed at the four corners.

[0044] The auxiliary support mechanism 5 includes a sliding seat 51, a vertical telescopic member 52 and a transverse driving member 53. The sliding seat 51 is slidably connected to the mounting frame 231 in the lateral direction. The sliding seat 51 is installed on the mounting frame 231 through a slide rail-slider assembly 54. The vertical telescopic member 52 is installed on the sliding seat 51, and the vertical telescopic member 52 is used to abut against the cross beam 13 of the inner storage position 11. The vertical telescopic member 52 is an oil cylinder or a linear module, and the transverse driving member 53 is a cylinder, a linear module or an electric cylinder. The vertical telescopic member 52 is installed on the sliding seat 51, and the transverse driving member 53 is used to drive the sliding seat 51 to reciprocate laterally.

[0045] A roller 55 is provided at the lower end of the vertical telescopic member 52. The roller 55 is a roller or a ball. In this embodiment, it is specifically a roller. The axis of the roller is along the longitudinal direction. There are two rollers, and the two rollers are arranged side by side in the lateral direction. The roller is installed at the lower end of the vertical telescopic member 52 through a roller seat 551. The auxiliary support mechanism 5 abuts against the cross beam 13 of the inner storage position 11 through the roller. The lifting movement trajectory of the roller seat 551 intersects with the side edge of the bearing member 233, so that the roller can be used to support the bearing member 233.

[0046] The implementation principle of a three-dimensional warehouse for storing chemical fibers in an embodiment of this application is as follows: During the process of the cargo conveying device 23 conveying goods to the outer storage position 12 of the three-dimensional shelf 1, before the carrier 233 moves to the inner storage position 11, the rollers of the auxiliary support mechanism 5 are first moved to the cross beam 13 of the inner storage position 11, and then the lateral drive mechanism 232 drives the carrier 233 to move towards the outer storage position 12. During this process, the carrier 233 passes through the rollers of the auxiliary support mechanism 5 and is supported by the rollers, so that part of the gravity of the goods acts on the inner storage position 11 through the rollers. When the carrier 233 abuts against the roller seat 551, the vertical telescopic member 52 can also perform telescopic adjustment, and the lateral movement drive member 53 can also drive the vertical telescopic member 52 to move laterally for adjustment. After the goods are placed, the carrier 233 is first retracted and reset laterally, and then the rollers of the auxiliary support mechanism 5 are raised and reset. Embodiment 3

[0047] Refer to Figures 5 - 7 In this embodiment, the difference from Embodiment 1 is that the cargo conveying device 23 further includes a suspension traction mechanism 6. There are two sets of suspension traction mechanisms 6, and the two sets of suspension traction mechanisms 6 respectively correspond to the two ends of the carrier 233 along the lateral direction. Each set of suspension traction mechanisms 6 has two, and the two suspension traction mechanisms 6 respectively correspond to the two sides of the same end of the carrier 233. The suspension traction mechanism 6 is used to apply a traction force to the front end of the carrier 233.

[0048] Refer to Figure 5 The suspension traction mechanism 6 includes a stay cable 61, a fixed pulley 62 and a hook assembly 63. The fixed pulley 62 is installed on the side of the mounting frame 231. One end of the stay cable 61 is fixedly connected to the front end of the carrier 233, and the other end of the stay cable 61 is inclined upward and bypasses the fixed pulley 62 and is connected to the mounting frame 231. A plurality of stretch springs 64 of different specifications are sleeved on the stay cable 61. The two ends of the stretch spring 64 are respectively connected to the stay cable 61. The two ends of the stretch spring 64 can be fixed to the stay cable 61 by wire rope clips or fixed to the stay cable 61 by wire bundling. When the stretch spring 64 is in a relaxed state, the part of the stay cable 61 located inside the stretch spring 64 forms a buffer section 611 with a zigzag extension, and the length of the buffer section 611 in the straight state is less than the limit stretching dimension of the stretch spring 64.

[0049] Refer to Figure 5 and Figure 6, the stay cable 61 is detachably connected to the mounting bracket 231 through a hook assembly 63. The hook assembly 63 includes a hook seat 631 and a hook 632. The hook 632 is connected to the stay cable 61, and the hook seat 631 is connected to the mounting bracket 231. A magnet 633 is embedded at the end of the hook 632, and the hook seat 631 is provided with a hook slot 634 for the hook 632 to hook into; a compression spring 635 is arranged in the hook slot 634. The compression spring 635 is used to prevent the end of the hook 632 from entering the hook slot 634. The hook seat 631 is provided with an electromagnet 636. The magnetic attraction force between the electromagnet 636 and the magnet 633 can force the end of the hook 632 to overcome the elastic force of the compression spring 635 and enter the hook slot 634.

[0050] The hook seat is provided with a guiding groove 637. The guiding groove 637 extends vertically, and the notch of the guiding groove 637 faces the horizontal direction. The guiding groove 637 is used to guide the hook 632 to the hook slot 634.

[0051] The implementation principle of an embodiment of a three-dimensional chemical fiber storage warehouse in this application is as follows: when the cargo conveying device 23 conveys goods, the bearing member 233 moves under the driving action of the lateral driving mechanism 232. When the stay cable 61 is connected to the mounting bracket 231, when the bearing member 233 moves, the stay cable 61 is subjected to a tensile force, causing the tension spring 64 on the stay cable 61 to undergo tensile deformation, causing the stay cable 61 to elongate. During the elongation process of the stay cable 61, according to the different elastic modulus specifications, each tension spring 64 reaches the maximum tensile deformation amount in sequence, and at the same time, the tensile force of the stay cable 61 gradually increases to adapt to the change in the magnitude of the moment of the bearing member 233.

[0052] When the cargo conveying device 23 moves in the opposite direction of the lateral movement stroke, it can convey goods to different shelves. When the cargo conveying device 23 conveys goods to one of the shelves, the stay cable 61 of one set of suspension traction mechanisms 6 is connected to the mounting bracket 231 through the hook assembly 63, and the hook assemblies 63 of the other set of suspension traction mechanisms 6 remain in a decoupled state. When the hook assembly 63 comes into play, the electromagnet 636 is energized, causing the hook 632 to hook into the hook slot 634 under the action of the magnetic attraction force between the magnet 633 and the electromagnet 636. When the electromagnet 636 is de-energized, the hook 632 is disengaged from the hook slot 634 under the action of the compression spring 635, putting the hook assembly 63 in a decoupled state. By controlling the energization and de-energization of the electromagnet 636, the connection state of different stay cables 61 can be controlled.

[0053] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
