Description

Technical Field

[0001] The invention relates to the technical field of warehousing logistics equipment, in particular to an ultra-high and heavy-load stacker. Background Art

[0002] In modern warehouse management, stackers, as the core logistics equipment of automated high-bay warehouses, shuttle back and forth in the aisles of shelves, and are used in conjunction with shelves to achieve cargo distribution management. With the modernization and intelligentization of China's industry, the logistics industry has also developed rapidly. Traditional stackers can no longer meet the needs of modern cargo storage management in current industrial plants. Ultra-high high-bay warehouses are the inevitable product of the modernization of warehousing and logistics.

[0003] Due to technical reasons, the ultra-high stacker used in ultra-high stereoscopic warehouses has an ultra-high overall structure, with a column height of about 30 meters. The structural dimensions of the stacker are not only large but also heavy. The rigidity, strength and stability of the whole machine are poor. Especially when the operating speed and acceleration are high during the storage and retrieval of goods, the stacker is prone to excessive inertia, and its metal structure will have a large deflection deformation, resulting in inaccurate equipment positioning, unbalanced operation, and long positioning time during operation, which seriously affects the efficiency of warehousing.

[0004] After searching, the patent number of the aisle stacker top braking device and method is CN201910773346.8, which proposes a new electromagnetic clutch-controlled braking device, which controls and changes the different friction modes of the roller at the end of the brake shaft on the guide rail surface through the electromagnetic clutch, thereby realizing point braking and continuous braking under high-speed operation, achieving the design purpose of both improving the braking efficiency and reducing the impact force on the shelf when the stacker starts and stops.

[0005] Another patent retrieved is a super-high stacker column structure with patent number CN202122418029.X. This structure has a cross beam arranged through two main beams, and a diagonal bracing beam is arranged between the cross beams. The main beam, the cross beam and the diagonal bracing beam form a hollow triangular structure. The triangular structure has strong stability, so that the column structure composed of the main beam, the cross beam and the diagonal bracing beam is stronger than a single rectangular tube column structure. The main beam, the cross beam and the diagonal bracing beam are all rectangular tubes with a hollow structure, so that the overall mass of the column structure is less than the column structure welded by steel plates and steel sections.

[0006] However, although the top brake device can reduce the shaking of the stacker when parking to a certain extent, it cannot ensure the stability of the stacker when parking quickly due to the defect of inconsistent control of the top and bottom rails;

[0007] The above-mentioned stacker column structure is welded by main beams, cross beams and diagonal bracing beams, which has a complex structure, is not easy to mass produce, has high cost, and is not suitable for heavy-load stackers.

[0027] 1. The present invention adopts an optimized design of setting a travel motor on the upper beam. The travel motors of the upper and lower beams accelerate and decelerate at the same time, which suppresses the swing of the upper part of the column and greatly reduces the deformation of the main structure. It satisfies the stacker to start and stop quickly with a large acceleration, run smoothly on the guide rail, have faster positioning, and improve efficiency.

The pull beam and the columns cooperate effectively, and under the comprehensive effect, the left and right shaking amount of the columns when the fork is picking up and releasing goods is significantly reduced, thereby achieving precise alignment and meeting the requirements for accurate storage and retrieval of goods.

[0029] 3. The present invention can effectively distribute the compressive stress by designing the side guide wheels with a double-wheel structure, which can reduce the selection of the wall thickness of the column and the wear of the guide surface. On the other hand, the column of the super-high stacker is formed by splicing multiple columns. When there are gaps and unevenness at the joints, the side guide wheels with a double-wheel structure can effectively reduce vibration and noise when passing.

[0030] 4. The present invention can fully detect the presence, size, height and other information of the cargo by arranging multiple cargo detectors on the cargo rack to ensure that the cargo is always in a qualified and standardized position. In addition, the auxiliary limit plates on both sides of the telescopic fork can automatically correct the position of the pallet when extended to prevent cargo damage or access failure caused by pallet tilt or offset. This intelligent design not only improves the safety of the operation, but also reduces the need for manual intervention.

[0031] 5. The present invention places the drag chain in a drag chain frame, and effectively restricts the drag chain through the drag chain frame, thereby preventing the drag chain from shaking significantly when the equipment moves, reducing the impact of the shaking on the drag chain, and ensuring the service life of the drag chain. At the same time, by arranging a shock-absorbing and sound-absorbing sponge strip on the inner side of the drag chain frame, the risk of the drag chain hitting the inner side of the drag chain frame to generate noise and damage the drag chain is further reduced.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] For example, see Figure 1-9 , an ultra-high and heavy-load stacker, comprising a stacker bracket 1, two columns 11 are symmetrically installed on the top of the stacker bracket 1, guide rails 15 are laid on the top and bottom of the two columns 11, displacement components are arranged on the two columns 11, and a cargo platform component 3 for moving goods with an auxiliary displacement component is also arranged between the two columns 11, the displacement component comprises an upper crossbeam component 2 installed on the top of the two columns 11 and a lower crossbeam component 4 installed at the bottom of the two columns 11, and the lower crossbeam component 4 is also provided with a lifting mechanism for lifting the pallet storing goods with the auxiliary cargo platform component 3, an electric control box 12 is also arranged on one of the stacker brackets 1, a plurality of maintenance tables 13 for workers to conveniently inspect are also arranged on one side of one of the columns 11, a plurality of pulling beams 14 for increasing the stability of the columns 11 are also arranged between the two columns 11, and a drag chain frame is also arranged on the column 11 close to the electric control box 12, a drag chain is arranged in the drag chain frame, and the moving end of the drag chain is fixed to the cargo rack 31;

[0045] When in use, first start the upper beam assembly 2 and the lower beam assembly 4, and use the upper beam assembly 2 and the lower beam assembly 4 to move the stacker bracket 1 along the guide rail 15, so that the two columns 11 drive the cargo platform assembly 3 to move at the same time. When it moves to the specified position, close the upper beam assembly 2 and the lower beam assembly 4, start the lifting assembly, and drive the cargo platform assembly 3 to move through the lifting assembly, lift the cargo platform assembly 3 to the height where the goods are, and move the goods from the shelf or onto the shelf through the cargo platform assembly 3 to complete the stacking work;

[0046] At the same time, by placing the drag chain in the drag chain frame, the risk of long-distance drag chains swaying during the movement of the stacker is avoided. Shock-absorbing and sound-absorbing sponge strips are pasted on the inside of the drag chain frame to further reduce the risk of the drag chain hitting the inside of the drag chain frame to generate noise and damage the drag chain.

[0047] For example 2, please refer to Figure 1 , Figure 2 and Figure 3 The upper crossbeam assembly 2 includes an upper beam frame 21, the two ends of the upper beam frame 21 are respectively fixed to the tops of the two columns 11, a fixed frame is installed on one end of the upper beam frame 21, and an upper crossbeam travel motor 22 is installed at the bottom of the fixed frame. The output end of the upper crossbeam travel motor 22 is fixedly connected to the upper crossbeam travel driving wheel 23 through a coupling, and the fixed frame is also rotatably connected to the upper crossbeam travel driven wheel 24. The upper crossbeam travel driving wheel 23 and the upper crossbeam travel driven wheel 24 are respectively located on both sides of the top guide rail 15, and the upper crossbeam travel driving wheel 23 and the upper crossbeam travel driven wheel 24 are in contact with the side wall of the guide rail 15. Two upper crossbeams are also arranged on the fixed frame. Travel guide wheels 26, two upper beam travel guide wheels 26 are respectively located on both sides of the guide rail 15, and a torque limiter 25 for adjusting the friction between the upper beam travel active wheel 23 and the upper beam travel driven wheel 24 and the guide rail 15 is also provided on the fixed frame, and an upper beam laser rangefinder 27 is also provided on the upper beam frame 21, and the lower beam assembly 4 includes a lower beam frame 41, and the lower beam frame 41 is provided with a lower beam travel motor 42, and the output end of the lower beam travel motor 42 is connected to the lower beam travel wheel, and the lower beam travel wheel is in contact with the bottom guide rail 15, and a lower beam laser rangefinder 43 is also provided on the lower beam frame 41;

[0048] When in use, first start the upper beam travel motor 22 on the upper beam frame 21 and the lower beam travel motor 42 on the lower beam frame 41, so that the upper beam travel motor 22 drives the upper beam travel active wheel 23 and the upper beam travel driven wheel 24 to slide on the upper guide rail 15, and the lower beam travel motor 42 drives the lower beam travel wheel to slide on the lower guide rail 15, so that the upper beam frame 21 and the lower beam frame 41 move synchronously. By setting the upper beam travel motor 22 on the upper beam frame 21, when in use, by accelerating and decelerating the upper beam travel motor 22 and the lower beam travel motor 42 at the same time, the swing of the column 11 during movement is greatly reduced, and the stability of the overall device is greatly increased;

[0049] By setting a torque limiter 25 between the upper beam travel driving wheel 23 and the upper beam travel driven wheel 24, the pressure between the upper beam travel driving wheel 23 and the upper beam travel driven wheel 24 and the guide rail 15 is adjusted by adjusting the extrusion force of the torsion spring on the torque limiter 25 during use, thereby changing the friction between the upper beam travel driving wheel 23 and the torque limiter 25 and the guide rail 15, so that the upper beam travel driving wheel 23, the upper beam travel driven wheel 24 and the guide rail 15 always maintain a suitable friction, making the overall operation more stable. At the same time, the setting of the torque limiter 25 can prevent the upper beam travel motor 22 from locking due to accidents and causing damage to the equipment;

[0050] At the same time, when in use, the distance meter set on the upper beam frame 21 and the lower beam frame 41 further ensures the synchronization of the upper and lower beams during operation and accurate positioning.

[0051] For example 3, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The cargo platform assembly 3 includes a cargo rack 31, and multiple side guide wheel assemblies 5 are arranged on both sides of the cargo rack 31. The multiple side guide wheel assemblies 5 are respectively slidably connected to the two columns 11. The cargo rack 31 is connected to the two columns 11 through the side guide wheel assemblies 5 on both sides. A pulley 33 is also arranged on one side of the cargo rack 31, and the pulley 33 is connected to the output end of the lifting mechanism. An emergency brake switch is also arranged on the pulley 33. A plurality of multi-stage telescopic forks 32 are also arranged on the cargo rack 31, and each multi-stage telescopic fork 32 is also provided with a transmission mechanism, which is composed of a transmission chain, a driving wheel, and a sprocket shaft. A driving motor is arranged on the cargo rack 31, and the output end of the driving motor is connected to the driving wheel through a coupling. The multi-stage telescopic fork 32 is telescoped through the transmission chain, the driving wheel, and the sprocket shaft. The multiple multi-stage telescopic forks 32 are all arranged on the top of the cargo rack 31. The cargo rack 31 is also equipped with a plurality of forks for detecting the cargo on the multi-stage telescopic forks 32. A cargo detector 34 for detecting the position of the cargo, each multi-stage telescopic fork 32 is also provided with an auxiliary positioning mechanism, the side guide wheel assembly 5 includes a side guide wheel bracket 51, two side guide wheel bodies 52 are rotatably connected in the side guide wheel bracket 51, the arc surfaces of the two side guide wheel bodies 52 are in contact with one side of the column 11, and a side guide wheel eccentric shaft 53 is also provided on the side of the side guide wheel bracket 51 close to the loading rack 31, and the other end of the side guide wheel eccentric shaft 53 passes through the side wall of the loading rack 31 and extends to On the inner side of the cargo rack 31, an extended end of the side guide wheel eccentric shaft 53 is installed with an axis end fixing plate 55, and a plurality of anti-rotation limit holes 56 are provided on the axis end fixing plate 55. The side guide wheel eccentric shaft 53 is also provided with an eccentric shaft adjustment hole 54 for assisting the side guide wheel eccentric shaft 53 to adjust the side guide wheel body 52. ​​The lifting mechanism includes a hoist 6 installed on one side of the column 11, and a steel cable 61 is provided on the hoist 6. The other end of the steel cable 61 extends to the pulley 33 on the cargo rack 31.

[0052] When using the cargo platform assembly 3, first start the hoist 6 so that the steel cable 61 drives the cargo rack 31 to slide up and down between the two columns 11 through the multiple sets of side guide wheel assemblies 5, so that the cargo rack 31 slides to the height of the cargo, and then start the driving motor on the cargo rack 31. The driving motor drives the transmission chain, the driving wheel, and the sprocket shaft to cooperate with each other to make the multi-stage telescopic fork 32 extend outward to the bottom of the pallet inserted under the cargo (the telescopic principle of this part is the prior art, which can be realized by the prior art means and will not be described in detail here), lift the cargo rack 31 upward so that the multi-stage telescopic fork 32 contacts the bottom of the pallet, retract the multi-stage telescopic fork 32, and the pallet and the cargo on the pallet are removed from the shelf, and wait for the next step to move the cargo to the desired position;

[0053] When the carrier 31 slides on the column 11, the side guide wheel bodies 52 in the side guide wheel brackets 51 arranged on both sides of the carrier 31 slide along the side walls of the column 11, making the sliding of the carrier 31 more stable. At the same time, the double wheel structure can effectively distribute the pressure and reduce the wear on the guide surface. At the same time, the column 11 in the device is formed by splicing multiple pieces. When there are gaps and unevenness at the joints, the double wheel structure can effectively reduce vibration and noise when passing through.

[0054] The connecting section between the side guide wheel eccentric shaft 53 and the side guide wheel bracket 51 and the shaft section installed on the frame of the cargo rack 31 are eccentrically designed, and the two shaft centers are not in a straight line. The eccentric design can facilitate the adjustment of the gap between the side guide wheel body 52 and the left and right columns 11. When adjustment is needed, tools are used to insert the eccentric shaft adjustment holes 54 of the side guide wheel assembly 5 respectively, and the side guide wheel eccentric shaft 53 is rotated to make the side guide wheel body 52 close to the left and right columns 11. In order to prevent the side guide wheel eccentric shaft 53 from reversing and loosening, a shaft end fixing plate 55 is set at the shaft end of the side guide wheel eccentric shaft 53, and the shaft end fixing plate 55 is provided with an anti-rotation limit hole 56. When the side guide wheel eccentric shaft 53 is rotated to a suitable position, a screw is passed through the anti-rotation limit hole 56 to fix the shaft end fixing plate 55, which effectively prevents the side guide wheel eccentric shaft 53 from rotating and loosening.

[0055] By means of the auxiliary positioning assembly provided on the multi-stage telescopic fork 32, when the multi-stage telescopic fork 32 is extended outward, the auxiliary positioning assembly provided on the multi-stage telescopic fork 32 simultaneously moves with the multi-stage telescopic fork 32 and contacts the crossbeam at the bottom of the pallet, and the position of the pallet is adjusted by the multi-stage telescopic fork 32;

[0056] By setting up multiple cargo detectors 34 on the loading rack 31, when in use, the multiple cargo detectors 34 can detect whether there is cargo, whether the cargo is too wide, too long, too high, etc., which is convenient to use.

[0057] Example 4, please refer to Figure 4 , Figure 5 and Figure 6The auxiliary positioning mechanism includes auxiliary limiting plates 36 installed on both sides of the multi-stage telescopic fork 32, and multiple evenly distributed supporting ears are installed on both sides of each multi-stage telescopic fork 32, each supporting ear is hinged with a connecting rod through a rotating shaft, and a torsion spring is arranged in the rotating shaft, and the other ends of multiple connecting rods on the same side are hinged with adjacent auxiliary limiting plates 36, and each auxiliary limiting plate 36 is rotatably connected to a plurality of adjusting wheels 39 on the side away from the adjacent loading rack 31, and the top of the loading rack 31 is also provided with a plurality of groups of sockets 35, and each group of sockets 35 is respectively on the same axis as the adjacent multi-stage telescopic fork 32, and each group of sockets 35 is slidably plugged with a plug rod 37, and a rotating rod is also arranged on the supporting ears near the plug rod 37 on each multi-stage telescopic fork 32, and the top of each rotating rod is fixed to the adjacent connecting rod, and a connecting rope 38 is wound around each rotating rod, and the other ends of the plurality of connecting ropes 38 are respectively fixed to the adjacent plug rod 37;

[0058] When the multi-stage telescopic fork 32 is extended outwards under the action of the transmission mechanism, the auxiliary limit plates 36 on both sides of the multi-stage telescopic fork 32 are extended outwards along with the multi-stage telescopic fork 32 at the same time. When the multi-stage telescopic fork 32 is extended outwards, the connecting rope 38 is tightened under the action of the multi-stage telescopic fork 32. When the multi-stage telescopic fork 32 continues to be extended outwards, the tightened connecting rope 38 starts to drive the rotating rod at the other end to rotate, and the rotating rod drives the connecting rod to rotate, so that the connecting rod drives the auxiliary limit plates 36 to expand outwards, and at the same time, the torsion spring in the rotating shaft is contracted under force;

[0059] When the multi-stage telescopic fork 32 is inserted into the bottom of the pallet, the multiple adjustment wheels 39 provided on the side of the auxiliary limit plate 36 contact the crossbeam at the bottom of the pallet, and push the pallet straight as the auxiliary limit plate 36 is continuously expanded outward. When the multi-stage telescopic fork 32 is retracted, the torsion spring in the rotating shaft drives the rotating shaft to rotate in the opposite direction, so that the connecting rod drives the auxiliary limit plate 36 to rotate in the opposite direction and retract.

[0060] By opening a plurality of insertion holes 35 at the top of the carrier 31, the amount of the auxiliary limit plate 36 to be unfolded each time can be adjusted according to the different sizes of the pallets during use. When adjusting, it is only necessary to pull the insertion rod 37 out of the insertion hole 35 and insert it into another hole in the same group. When the insertion rod 37 is closer to the multi-stage telescopic fork 32, the width of the auxiliary limit plate 36 to be unfolded will be smaller, and vice versa.

[0061] The working principle of the present invention is: when in use, the lower beam travel motor 42 drives the lower beam assembly 4 to move linearly along the guide rail 15, and at the same time, the upper beam travel motor 22 is started to drive the upper beam travel driving wheel 23 and the upper beam travel driven wheel 24 to move along the upper guide rail 15, and the lower beam travel motor 42 and the upper beam travel motor 22 are synchronously controlled and driven to ensure that the upper and lower beams are in step with each other during the process of starting, running and stopping of the device;

[0062] After the two uprights 11 are parked at the set position, the lifting mechanism is also driven by the hoist 6 to lift the load rack 31 to the storage and retrieval position corresponding to the rack through the steel cable 61, and the multi-stage telescopic fork 32 with the goods placed on it is extended through the transmission mechanism, and the load rack 31 is lowered to store the goods with the pallet at the corresponding shelf position, and then the multi-stage telescopic fork 32 is retracted;

[0063] Or the multi-stage telescopic fork 32 is extended to lift the carrier 31, and the goods are placed on the multi-stage telescopic fork 32 along with the pallet, and then the multi-stage telescopic fork 32 is retracted to wait for instructions to perform the next step of walking and storing and retrieving goods, and this is repeated to achieve the lifting, lowering, storing and retrieving of the carrier 31;

[0064] At the same time, when the multi-stage telescopic fork 32 is extended outward, the auxiliary limit plates 36 on both sides of the multi-stage telescopic fork 32 are extended outward along with the multi-stage telescopic fork 32 at the same time, and the connecting rope 38 is tightened under the action of the multi-stage telescopic fork 32. The tightened connecting rope 38 starts to drive the rotating rod at the other end to rotate, and the rotating rod drives the connecting rod to rotate, so that the connecting rod drives the auxiliary limit plates 36 to expand outward, and the multiple adjustment wheels 39 provided on the side of the auxiliary limit plates 36 contact the crossbeam at the bottom of the pallet, and push the pallet straight in the process of the auxiliary limit plates 36 continuously expanding outward;
