Description

Technical Field

[0001] The present invention relates to the technical field of cargo transportation devices, and in particular to an interval type stacker loading platform and a method thereof for storing and retrieving ton bag stacks. Background Art

[0002] A ton bag is a flexible container used to hold powdered or granular materials. In the warehousing system, the batch size of ton bags is relatively large. When using traditional stackers to load and unload ton bag pallets, they are all carried out on a single loading platform, which is not efficient. If large quantities of goods need to be loaded and unloaded, a single loading platform will be difficult to meet the actual needs of customers. In addition, ton bags are flexible. To ensure efficiency, ton bags are stacked in multiple layers, but they are prone to skew when stacked high. In addition, with the high-speed operation of the stacker, the excessively fast running speed can easily cause the ton bags to fall, further restricting the efficiency of ton bag materials in and out of the warehouse.

[0003] Chinese patent CN221215577U discloses a light-load stacker, which has a plurality of clamping arms arranged opposite to each other on both sides of the top of a loading platform, and infrared sensing devices are also arranged on both sides of the top of the loading platform, and the signal output end of the infrared sensing device is connected to the signal input end of the clamping arm; when the goods are forked onto the loading platform, the clamping arms will clamp the goods to ensure the stability of the goods on the loading platform, prevent them from tipping over or falling, and eliminate safety hazards.

[0004] The above-mentioned device limits the cargo by means of the clamping arms, thereby preventing the cargo from tipping over during high-speed movement. However, the number of loading stations is limited, which restricts the efficiency of cargo loading. Some existing devices improve the efficiency of warehousing and out-of-warehouse by setting up multiple loading stations at intervals. However, this will cause a waste of platform space during specific operations. When dealing with some larger cargoes, the use of existing devices will be limited. In summary, there is still room for improvement in the above-mentioned device.

[0005] Therefore, it is necessary to provide a spacing type stacker loading platform and method for storing and retrieving ton bag stacks to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0031] like Figure 1-Figure 6 As shown, a spacing type stacker loading platform and method for storing and retrieving ton bag stacks include a column 1. In actual use, the column 1 is installed at the lower cross beam of the stacker to facilitate the movement of the column 1 in the warehouse. A loading platform 3 is installed in the column 1, and the loading platform 3 can move in the vertical direction along the column 1. The specific connection structure between the column 1 and the loading platform 3 is a mature technical means in the stacker and will not be elaborated here.

[0032] A set of telescopic forks 4 are provided on both sides of the top of the loading platform 3, and through this structure, two groups of goods can be forked and transported at one time when in use;

[0033] Furthermore, in order to prevent the goods from tipping over during high-speed transportation, limit plates 2 can be arranged on both sides of the top of the loading platform 3 and between the two sets of telescopic forks 4. Figure 3 As shown, a hanger 8 is provided on the outer side of the limit plate 2, the hanger 8 is fixedly connected to the loading platform 3, and a driving unit matched with the limit plate 2 is fixedly installed on the hanger 8, and the driving unit can drive the limit plate 2 to move in the horizontal direction, so as to limit the goods and prevent them from tipping over. In actual use, the stacker is moved to the side of the goods to be forked, and the telescopic fork 4 is extended to the bottom of the pallet. The pallet and the goods on the top of the pallet are driven to the loading platform 3 by the telescopic fork 4, and the limit plate 2 is driven to move to one side of the goods by the driving unit to limit it, so as to prevent the goods from tipping over during movement.

[0034] Although the above structure can limit the position of two groups of goods when in use, in actual use, since the limiting plate 2 is arranged in the middle part of the loading platform 3, the utilization rate of the loading platform 3 is greatly reduced. When the lateral size of the goods is large, this device will be subject to certain restrictions when in use. Therefore, according to this problem, the above structure is further optimized. Specifically, the middle part of the loading platform 3 is sunken to form a concave portion 301. For details, please refer to Figure 2 As shown, a limiting component is arranged at the recessed portion 301. In actual use, when the limiting component is retracted, the cargo on the telescopic fork 4 can be squeezed and limited, and when the limiting component is expanded, the cargo can be released, thereby facilitating the removal of the cargo.

[0035] like Figure 4 As shown, the above-mentioned limiting assembly includes two groups of connecting rods 11, and the two groups of connecting rods 11 are arranged at the front and rear sides of the recessed portion 301. The number of each group of connecting rods 11 is set to multiple and cross-arranged. Specifically, the two connecting rods 11 on the same layer are cross-arranged and rotated at the center, while the connecting rods 11 of the upper and lower layers rotate at the ends, so that the overall connecting rods 11 have a scissor-type telescopic structure. A cross bar 5 is provided between the front and rear groups of connecting rods 11. Specifically, both ends of the cross bar 5 pass through the connecting rod 11 and rotate with it through bearings. In actual use, when the two connecting rods 11 at the bottom are away from each other, the multiple connecting rods 11 in the scissor-type telescopic structure will drive the cross bar 5 to move outward, thereby pressing against the side of the cargo, which is beneficial to limiting the cargo and preventing the cargo from tipping over during transportation.

[0036] like Figure 3-Figure 10 As shown, as a further optimization of the above scheme, a pressure plate 7 can be installed on the cross bar 5, the cross bar 5 passes through the pressure plate 7 and is fixedly matched with it, a positioning rod 17 is provided at one end of the connecting rod 11, and the cross section of the positioning rod 17 is set to be L-shaped, and a strip-shaped positioning groove 18 is opened on the side of the positioning rod 17 opposite to the cross bar 5, referring to Figure 8 As shown, a slider 19 is elastically installed at the end surface of one end of the cross bar 5 passing through the connecting rod 11 and close to the positioning rod 17, and a pressing block 20 is fixedly arranged at the end of the sliding block 19 away from the cross bar 5. The pressing block 20 is truncated cone-shaped, and the outer peripheral surface of the pressing block 20 is a conical surface 2001. Through this structure, when the limiting assembly is expanded to make the cross bar 5 gradually approach the positioning rod 17, the pressing block 20 can enter the positioning groove 18, and when the limiting assembly is contracted, the positioning rod 17 can be driven to move synchronously with the cross bar 5 in the horizontal direction through the pressing block 20. When the pressure between the pressing block 20 and the side edge of the positioning groove 18 increases, the pressing block 20 can be compressed into the sliding block 19 and finally led out of the positioning groove 18;

[0037] A gear 16 is fixedly sleeved on one end of the crossbar 5 close to the positioning rod 17, and a rack 15 meshing with the gear 16 is fixedly embedded on the side wall of the positioning rod 17;

[0038] Reference Figure 5 As shown, a fixing plate 14 is provided on one side of the stage 3 close to the positioning rod 17, the fixing plate 14 is fixedly connected to the stage 3, at least one through slot is provided on the fixing plate 14, and a guide block 12 is fixedly provided on one side of the positioning rod 17 close to the fixing plate 14, the guide block 12 is slidably provided in the through slot, specifically, a slide bar 13 is fixedly provided in the through slot, the slide bar 13 passes through the guide block 12 and slidably cooperates with the guide block 12, a limit spring is also sleeved on the outer side of the slide bar 13, the limit spring is located between the guide block 12 and the inner end face of the through slot, through this structure, the positioning rod 17 and the stage 3 can be elastically connected;

[0039] Reference Figure 5 As shown, a stopper 21 is fixedly provided on the inner bottom surface of the through groove, and the stopper 21 is located between the two guide blocks 12. In the initial state, the guide block 12 is in contact with the stopper 21. During the deployment of the limit assembly, the pressure block 20 can contact and squeeze the positioning rod 17, but the setting of the stopper 21 can prevent the positioning rod 17 from moving. When the pressure block 20 is placed in the positioning groove 18 and moves outward with the cross bar 5, the positioning rod 17 can be driven to move outward by the cooperation between the pressure block 20 and the positioning groove 18.

[0040] Reference Figure 7 As shown, the top surface of the pressing plate 7 is recessed inward to form a notch 701, while the bottom surfaces of the pressing plate 7 are recessed inward to form contraction portions 702. Fig. 9 As shown, the inner side surface of the pressure plate 7 is concave inward near the bottom end to form an inner recess 704. Through this structure, when the limiting assembly contracts to make the upper and lower adjacent cross bars 5 approach each other, the inner recess 704 on the pressure plate 7 can move down to the cross bar 5 below the pressure plate 7 and be placed on the outside of the cross bar 5. Afterwards, as the limiting assembly continues to contract, the cooperation of the upper and lower cross bars 5 can drive the pressure plate 7 to move to one side of the goods on the pallet and press the goods.

[0041] When two groups of goods need to be loaded on the loading platform 3, the stacker can drive the column 1 to move to the side of the goods, and move the pallet loaded with goods onto the loading platform 3 through one of the telescopic forks 4. At this time, the limit assembly can be retracted to allow the multiple cross bars 5 to move downward in the vertical direction. During this process, the inner concave portion 704 at the bottom end of the pressing plate 7 can move to the cross bar 5 below the pressing plate 7. Afterwards, as the cross bar 5 continues to move downward, the cooperation of the upper and lower adjacent cross bars 5 can drive the pressing plate 7 to move toward the direction close to the goods and finally press on the goods. At the same time, the limit plate 2 can be driven to press on one side of the goods through the driving unit;

[0042] When one group of goods is loaded, the stacker moves to the side of another group of goods, and then drives the limit assembly to expand upward to reserve space for loading goods. When the goods are moved to the loading platform 3 by another telescopic fork 4, the limit assembly can be retracted again. In this process, the pressure plate 7 on the cross bar 5 cooperates with the limit plate 2 to limit the goods to prevent them from tipping over during transportation.

[0043] When the cargo to be loaded is large and requires the two telescopic forks 4 to work together, the limit assembly can be expanded upward to the limit position. During this process, the pressure block 20 at one end of the cross bar 5 will contact the positioning rod 17. The positioning rod 17 squeezes the pressure block 20 so that the pressure block 20 can be retracted into the slider 19. When the pressure block 20 is aligned with the positioning groove 18, the pressure block 20 can pop out and insert into the positioning groove 18. At the same time, the gear 16 on the outside of the cross bar 5 can mesh with the rack 15 on the positioning rod 17. When the limit assembly is retracted, multiple cross bars 5 can move downward and gradually approach each other. During this process, the cross bar 5 will move outward, so that the positioning rod 17 can be driven to move outward through the pressure block 20. In the process of the cross bar 5 moving downward relative to the positioning rod 17, the gear 16 can be moved downward relative to the positioning rod 17. 6 is meshed with the rack 15 to drive the cross bar 5 to rotate, thereby driving the pressure plate 7 to deflect inward, so that the bottom end of the pressure plate 7 is placed on the inner side of the cross bar 5 below the pressure plate 7, and as the positioning rod 17 moves, the limit spring will be gradually compressed, so that the pressure between the pressure block 20 and the side edge of the positioning groove 18 increases, so that the pressure block 20 is compressed in the slider 19 and finally moves out of the positioning groove 18. At this time, the positioning rod 17 will be reset, but because the bottom end of the pressure plate 7 is already on the inner side of the lower cross bar 5, therefore, when multiple cross bars 5 shrink downward and approach, the pressure plate 7 is limited by the lower cross bar 5 and can be deflected in a direction parallel to the connecting rod 11, which is conducive to shrinking the cross bar 5, the connecting rod 11 and the pressure plate 7 into the recessed portion 301. At this time, large-sized goods can be transported through the cooperation of the two sets of telescopic forks 4.

[0044] In summary, this device can transport multiple groups of goods by means of two sets of telescopic forks 4, thereby improving the transportation efficiency, and the limiting assembly cooperates with the limiting plate 2 to limit the goods on the telescopic fork 4, and when transporting large-sized goods, the limiting assembly can be retracted into the recessed portion 301, thereby freeing up space on the loading platform 3 for loading large-sized goods, thereby expanding the overall use range of the device.

[0045] like Figure 1-Figure 5 , Figure 8 As shown, slide plates 6 are provided on both sides of the bottom of the inner cavity of the recessed portion 301, and the bottom cross bar 5 passes through the slide plate 6 and rotates therewith, a guide rod 10 is fixedly provided in the recessed portion 301, the guide rod 10 passes through the slide plate 6 and slides therewith, and a screw rod 9 is provided in the recessed portion 301, both ends of the screw rod 9 are smooth rod portions and rotate with the stage 3, the screw rod 9 passes through the slide plate 6 and is threadedly connected therewith, and a motor is installed below the stage 3, and the output shaft of the motor is transmission-connected to one end of the screw rod 9 passing through the recessed portion 301, so as to drive the slide plate 6 to move, thereby causing the limit assembly to expand or contract.

[0046] In actual use, the pressing plates 7 may not be installed at the two groups of cross bars 5 located at the lower layer, so as to avoid the pressing plates 7 from overlapping the pallets in the horizontal direction, so that the pressing plates 7 can be pressed tightly against one side of the goods.

[0047] The driving unit includes structures such as a cylinder or a hydraulic rod, and the telescopic end of the driving unit is fixedly connected to the limit plate 2, and the limit plate 2 can be driven to move through this structure.

[0048] The end of the cross bar 5 is provided with a sliding groove that slidably cooperates with the slider 19 , and a spring is fixedly arranged between the inner end surface of the sliding groove and the slider 19 .

[0049] Reference Fig. 9 As shown, an inclined guide surface 703 is provided on one side of the top wall of the contraction portion 702. Through this structure, as the multiple cross bars 5 gradually approach each other in the vertical direction, the pressure of the lower cross bar 5 on the pressure plate 7 enables the pressure plate 7 to deflect in a direction parallel to the connecting rod 11. During this process, the guide surface 703 on the upper pressure plate 7 can contact the top of the lower pressure plate 7, thereby avoiding interference between the two pressure plates 7.
