Description

TECHNICAL FIELD

[0001] The present application relates to the field of stereoscopic storage, and more particularly to a stacking device for automatic storage and retrieval of long heavy materials and a stereoscopic storage system. BACKGROUND

[0002] Long heavy profiles are widely used in enterprises such as wind power generation and ship equipment manufacturing, and are indispensable materials in large-span, heavy-load and rapid construction scenarios. They often have multiple models, specifications and thicknesses, which greatly increase the difficulty of storage and retrieval. In a flat yard, multiple searches will be required for stacking, resulting in low space utilization, low storage and retrieval efficiency, and damage to the profiles during the search process. Large-scale automatic stereoscopic storage has emerged to significantly improve space utilization and storage and retrieval efficiency. However, the existing storage and retrieval methods still have the following shortcomings:

[0003] The existing long-stroke telescopic gear shaping adopts a belt drive to solve the two-stage telescopic problem, but the belt drive has the problem of poor synchronization of multiple mechanisms in series, and is prone to slipping under heavy load, making it difficult to meet the super heavy load working condition.

[0004] The gear shaping mechanism is connected to the chain and the translation mechanism, and the vertical movement is completed by the chain, which is flexible. After the gear shaping mechanism inserts and retrieves heavy load profiles, it is easily tilted due to the eccentricity of gravity. Therefore, the ordinary gear shaping mechanism can only insert and retrieve lighter profiles. SUMMARY

[0010] As a further improvement of the present application, the fixed base comprises a left base and a right base, the left base and the right base are arranged with a spacing therebetween, and a receiving groove is formed between the left base and the right base for receiving the driven large gear, the second linkage gear rack is arranged on the upper side of the left base and the right base, a waist-shaped hole is arranged on the left base and the right base along the length direction thereof, and the connecting rod is arranged in the waist-shaped hole.

[0011] As a further improvement of the present application, the driving mechanism comprises two driving gears, a first gear rack is arranged on the lower side of the first sliding rod, the first gear rack is engaged with the driving gears, so that the first sliding rod is driven by the driving gears to slide back and forth on the fixed base, and the driving gears are arranged at the middle part of the fixed base.

[0012] Another aspect of the present application provides a stereoscopic storage system, comprising a moving frame, a translation mechanism, a vertical conveying platform and a plurality of storage racks, the plurality of storage racks are arranged in the moving frame, the translation mechanism is arranged on the moving frame and above the storage racks in a translatable manner, the vertical conveying platform is arranged below the translation mechanism in a vertically movable manner through chain transmission, the moving frame is provided with an in-out storage buffer rack near the bottom, and the vertical conveying platform is provided with a plurality of stacking devices for automatic storage and retrieval of long and heavy materials as described in any one of the above.

[0013] As a further improvement of the stereoscopic storage system, the warehousing operation of the storage system comprises the following steps:

[0014] Step one, the profile to be warehoused can be conveyed to the in-out storage buffer rack through an external roller conveyor;

[0015] Step two, the translation mechanism tightens the chain to lift the vertical conveying platform to the top of the moving frame, then the translation mechanism translates along the track on the moving frame to above the in-out storage buffer rack, then the chain is released to lower the vertical conveying platform to the lower part of the profile to be warehoused, and the first-order and second-order sliding rods on the stacking device for automatic storage and retrieval of long and heavy materials on the vertical conveying platform are extended;

[0019] Wherein, the out-of-warehouse operation steps are executed in reverse of the above-mentioned warehousing steps.

[0020] The beneficial effects of this invention are that it utilizes the differential transmission principle to achieve two-stage extension of the first-order and second-order sliding rods, which serve as the shaping teeth. The two-stage shaping teeth are driven purely by gears, achieving linkage between the first and second-order shaping teeth. This pure gear transmission scheme significantly enhances the heavy-load capacity of the shaping tooth mechanism and improves the synchronization of multiple shaping tooth mechanisms in series. The extension ratio of the first and second-order shaping teeth can be adjusted by changing the preset transmission ratio of the differential gears. Single or multiple material insertions can be achieved by controlling the extension length. Simultaneously, the shaping tooth mechanism adopts a one-drive-multiple-action design, meaning that one motor can connect multiple shaping tooth mechanisms in series via a transmission shaft, achieving synchronous drive of multiple shaping tooth mechanisms and improving reliability and accuracy. Furthermore, by controlling the forward and reverse rotation of the transmission shaft, bidirectional extension and retraction of the shaping teeth can be achieved, improving the flexibility of the shaping tooth mechanism. This also enables the flexible insertion and removal of materials on both sides of the aisle using a single shaping tooth mechanism, contributing to weight reduction and further optimizing the layout of the automated warehouse. Various limiting structures, such as limiting grooves, are rationally set between the components of the shaping tooth mechanism, limiting the stroke while improving the reliability of the shaping tooth mechanism. In addition, limiting measures are adopted in the up-and-down movement of the toothed mechanism via the chain to prevent tipping after inserting or picking up heavy materials.

[0027] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0028] Reference Figure 1As shown, the stacking device for automatic storage and retrieval of long heavy materials in the embodiment comprises a fixed base 4, a first sliding rod 2 and a second sliding rod 1.

The fixed base 4 is provided with a driving mechanism, which is linked with the first sliding rod 2 to drive the first sliding rod 2 to slide on the fixed base 4. The first sliding rod 2 is provided with a driven mechanism, which is linked with the first sliding rod 2 and the second sliding rod 1 to drive the second sliding rod 1 to slide on the first sliding rod 2 when the first sliding rod 2 slides along the fixed base 4, and the upper side of the second sliding rod 1 is a fork rod bearing surface. In the working process, the driving mechanism provides power to move the first sliding rod 2 on the fixed base 4, and the driven mechanism drives the second sliding rod 1 to move on the first sliding rod 2 by using the power generated by the movement of the first sliding rod 2, thereby realizing the bearing and movement of the goods. Compared with the poor synchronization and easy slipping of heavy load in the background technology, the device adopts the driven mechanism as the driving mode of the second sliding rod 1, so that the rigid transmission mode such as gear and rack can better meet the super heavy load working condition and improve the stability and reliability of the device.

[0029] Further, referring to Figure 1 and Figure 3 , the driving mechanism comprises two driving gears 5, and the lower side of the first sliding rod 2 is provided with a first rack 21, which is engaged with the driving gear 5 to drive the first sliding rod 2 to slide back and forth on the fixed base 4, and the driving gear 5 is located at the middle part of the fixed base 4. The driving gear 5 rotates under the driving of the power source, and converts the rotary motion into the linear motion of the first sliding rod 2 through the engagement with the first rack 21. Compared with the belt transmission in the background technology, this driving mode avoids slipping and enhances the transmission stability, and can bear larger load.

[0030] Further, referring to Figure 1 , Figure 2 and Figure 3As shown, the driven mechanism includes a driven large gear 301 and a driven small gear 302, the driven small gear 302 is coaxially fixed on the end face of the driven large gear 301, the lower side of the second-order sliding rod 1 is provided with a second-order rack 11, the side wall of the first-order sliding rod 2 is provided with a first-order linkage rack 22 near the upper side, the upper side of the fixed base 4 is provided with a second-order linkage rack 41, the driven small gear 302 is rollably arranged between the first-order sliding rod 2 and the fixed base 4, and is in meshing with the second-order linkage rack 41 and the first-order linkage rack 22, and the driven large gear 301 is in meshing with the second-order rack 11. When the first-order sliding rod 2 moves on the fixed base 4, the driven small gear 302 is driven to rotate, the driven small gear 302 drives the coaxial driven large gear 301 to rotate, and the driven large gear 301 drives the second-order sliding rod 1 to move in meshing with the second-order rack 11. Compared with the background art, the driven mechanism design can accurately realize the synchronization of two-stage sliding, and better adapt to the super heavy load working condition.

[0031] Further, referring to Figure 4 and Figure 5 As shown, the cross section of the second-order sliding rod 1 is in a portal frame structure, the second-order rack 11 is arranged at the middle position of the top of the portal frame structure, the first-order sliding rod 2 includes a left rod 23 and a right rod 24 and a connecting rod 25, the two ends of the connecting rod 25 are fixed with the inner side walls of the left rod 23 and the right rod 24 respectively, so as to connect the left rod 23 and the right rod 24 to each other and form a channel for the driven large gear 301 to pass through between the left rod 23 and the right rod 24, the first-order rack 21 is arranged on the lower side of the left rod 23 and the right rod 24, a plurality of sliding columns are arranged on the inner side wall of the second-order sliding rod 1 near the lower side, and a plurality of sliding grooves are arranged on the outer side wall of the first-order sliding rod 2 near the upper side, and the plurality of sliding columns are arranged in the sliding grooves, so that the second-order sliding rod 1 is slidably arranged on the first-order sliding rod 2. The structure design provides space for the movement of the driven large gear 301, ensures the stability of the first-order sliding rod 2 and the second-order sliding rod 1, enhances the overall carrying capacity of the device, solves the problem of easy deformation of the structure under heavy load in the background art, and effectively realizes the slidable arrangement of the second-order sliding rod 1 on the first-order sliding rod 2 by using the combined structure of the sliding column and the sliding groove.

[0032] Further, referring to Figure 1 , Figure 2 and Figure 3As shown, the fixed base 4 includes a left base 42 and a right base 43, which are spaced apart from each other and form a containing groove containing the driven gear 301 therebetween, the two-order linkage rack 41 is arranged on the upper side of the left base 42 and the right base 43, the left base 42 and the right base 43 are both provided with a waist-shaped hole 44 extending along the length direction thereof, and the connecting rod 25 is arranged in the waist-shaped hole 44. The left base 42 and the right base 43 can provide space for containing the driven gear 301, and the combination of the waist-shaped hole 44 and the connecting rod 25 can limit the connecting rod 25 through the waist-shaped hole 44, thereby limiting the sliding of the first-order sliding rod 2.

The main transmission shaft 6 synchronously drives the two drive gears 5, ensures that the forces on both sides of the first-order sliding rod 2 are uniform, and more stably moves under the condition of super heavy load, thereby avoiding the movement deviation caused by uneven force.

[0034] Further, referring to Figure 6 As shown, a three-dimensional storage system includes a moving frame 14, a translation mechanism 7, a vertical conveying platform 8, and a plurality of storage racks 10. The plurality of storage racks 10 are arranged in the moving frame 14, the translation mechanism 7 is arranged on the moving frame 14 in a translatable manner and above the storage racks 10, the vertical conveying platform 8 is arranged below the translation mechanism 7 in a lifting manner through chain transmission, the moving frame 14 is provided with an in-out storage buffer rack 12 at a position close to the bottom, and the vertical conveying platform 8 is provided with a plurality of the above-mentioned stacking devices for automatically storing and taking long and heavy materials.

Compared with the background art, the problems of difficult storage and taking, low space utilization, low efficiency, and easy damage of long and heavy materials in storage are solved.

[0035] Further, the storage system includes the following steps:

[0036] Step one, the storage profile can be conveyed to the in-out storage buffer rack 12 through the external roller way. This step realizes the preliminary buffering of the profile and prepares for the subsequent transfer.

[0037] Step two, the chain of the translation mechanism 7 is tightened to lift the vertical conveying platform 8 to the top of the moving frame 14, then the translation mechanism 7 is translated along the track on the moving frame 14 to above the in-out storage buffer frame 12, then the chain is loosened to lower the vertical conveying platform 8 to the lower part of the profile to be stored, and the first-order sliding rod 2 and the second-order sliding rod 1 on the long heavy material automatic storage and retrieval facing the stacking device extend. Through the cooperation of the translation mechanism 7 and the chain, the vertical conveying platform 8 is accurately moved to the profile position, and the long heavy material automatic storage and retrieval facing the stacking device is extended to prepare for carrying the profile.

[0038] Step three, the chain of the translation mechanism 7 is tightened for a short distance to lift the vertical conveying platform 8, so that the profile to be stored is separated from the in-out storage buffer frame 12 and placed on the fork rod bearing surface on the upper side of the second-order sliding rod 1, then the first-order sliding rod 2 and the second-order sliding rod 1 are retracted, the profile to be stored is transferred to the center of the vertical conveying platform 8, and the chain of the translation mechanism 7 is further tightened to lift the vertical conveying platform 8 to the top of the moving frame 14. The transfer of the profile from the buffer frame to the vertical conveying platform 8 is realized, and the profile is adjusted to the appropriate position for transportation to the rack 10.

[0039] Step four, the translation mechanism 7 moves to above the aisle where the rack 10 to be stored is located, the chain below lowers the vertical conveying platform 8 to above the rack 10 to be stored, the first-order sliding rod 2 and the second-order sliding rod 1 on the long heavy material automatic storage and retrieval facing the stacking device on the vertical conveying platform 8 extend, and the profile to be stored thereon is translated to above the rack 10. The profile is accurately transported to above the corresponding rack 10, and the long heavy material automatic storage and retrieval facing the stacking device is extended to prepare for placing the profile.

[0040] Step five, the translation mechanism 7 further loosens the chain to lower the vertical conveying platform 8 for a short distance, and the profile to be stored is placed on the rack 10, then the first-order sliding rod 2 and the second-order sliding rod 1 are retracted to complete the storage work.
