Description

Technical Field

[0001] The utility model relates to automated warehousing logistics, in particular to a conveying device for a mother-and-child pallet. Background Art

[0002] The incoming pallets of some cargo units cannot be directly used on the conveyor line and the three-dimensional warehouse shelves. When entering the warehouse, they need to be placed on the mother pallet for transportation, that is, the mother-child pallet is combined. In the process of entering the warehouse, the goods are basically placed on the mother pallet on the conveyor line by manual forklift. The position of the mother-child pallet is aligned by manual forklift during the release process, and then the goods are entered into the warehouse through the conveyor line.

[0003] Manual forklifts are relatively untidy in placing goods, and often fail to meet the requirements for the flatness of all four sides of pallet goods for automated warehousing. When the size of the mother pallet and the child pallet are similar, the probability of the pallet being placed sideways increases. As a result, goods are prone to collision during transportation on the pallet, causing unnecessary safety accidents. At the same time, due to the uneven placement of the pallets, it is not convenient for the pallets to enter the conveyor line of the automated equipment. When placing the belt-carrying cargo unit on the mother pallet on the conveyor line, it is easy to tilt and dislocate, resulting in out-of-tolerance appearance, which affects the intelligent transportation and warehousing of the pallet cargo unit.

[0025] like Figure 2 As shown, the horizontal traction mechanism 2 includes a translation frame 21, a traction motor 22, a synchronous belt 24, a synchronous wheel 23, and a linear guide rail 25. The linear guide rail 25 and the synchronous wheel 23 are connected to the main frame 1. The synchronous wheel 23 is connected with the synchronous belt 24. The translation frame 21 is slidably connected to the linear guide rail 25, the translation frame 21 is fixedly connected to the synchronous belt 24, and the traction motor 22 is connected to and drives the synchronous wheel 231. The translation frame 21 is provided with a synchronous belt pressing block 29, and the synchronous belt pressing block 29 is fixedly connected to the synchronous belt 24. The traction motor 22 is preferably a reduction motor.

[0026] The horizontal traction mechanism 2 also includes a transmission shaft 26. The two ends of the top of the main frame 1 are connected to a linear guide 25 and a group of synchronous wheels 23.

[0027] The horizontal traction mechanism 2 also includes a tensioning assembly 28 for adjusting the tightness of the synchronous belt 24, and the tensioning assembly 28 is installed on the synchronous wheel 23. The tensioning assembly 28 can fine-tune the position of the synchronous wheel 23 on the main frame 1, thereby adjusting the spacing between the two synchronous wheels 23 on the synchronous belt 24, and then adjusting the tightness of the synchronous belt 24.

[0028] The horizontal traction mechanism 2 uses a reduction motor to drive two synchronous belts 24 with the same transmission shaft 26, and cooperates with the linear guide rail 25 to support and guide to achieve horizontal movement of the translation frame 21, ensuring the accuracy of horizontal positioning when transporting the pallet. The translation frame 21 is mainly used to fix the lifting mechanism 3 and is connected to the horizontal traction mechanism 2 through the synchronous belt 24.

[0029] The horizontal traction mechanism 2 consists of Figure 2 The key parts shown in the figure are composed of a traction motor 22 as the power output of the horizontal traction mechanism 2, which drives a synchronous belt 24 through a synchronous wheel 23, and the synchronous belt 24 connects the translation frame 21 and provides horizontal traction power for it, a linear guide rail 25 provides support and guidance for the translation frame 21, and the main frame 1 provides support for the entire mechanism, and the driven synchronous wheel 232 is driven to rotate by the driving synchronous wheel 231 and the synchronous belt 24, and the tensioning assembly 28 can adjust the tightness of the synchronous belt 24, and the bearing and the transmission support seat 11 fix the transmission shaft 26, and the coupling 27 connects the transmission shaft 26 and transmits power.

The horizontal traction mechanism 2 has accurate positioning and can meet the needs of automatic handling of sub-pallets.

[0030] like Figure 3 As shown, the lifting mechanism 3 includes a lifting support frame 31, a screw rod 33, a lifting motor 32, a fixed nut seat 34, and a support nut seat 35. The rotating fork mechanism 4 includes a fork support frame 41. The lifting motor 32, the fixed nut seat 34, and the support nut seat 35 are all connected to the lifting support frame 31. The two ends of the screw rod 33 are respectively connected to the fixed nut seat 34 and the support nut seat 35. The output end of the lifting motor 32 is connected to one end of the screw rod 33. The fork support frame 41 is provided with a lifting nut seat 42, and the lifting nut seat 42 is threadedly connected to the middle part of the screw rod 33. The lifting motor 32 is preferably a reduction motor, and the screw rod 33 is preferably a ball screw 33.

[0031] A lifting rail 36 is provided on the lifting support frame 31 , and the lifting rail 36 is parallel to the screw rod 33 . A lifting slider 43 is provided on the fork support frame 41 , and the lifting slider 43 is cooperatively connected with the lifting rail 36 .

[0032] The lifting mechanism 3 uses a reduction motor to drive the ball screw 33, which cooperates with the linear guide 25 to guide and drive the rotating fork mechanism 4 to perform lifting and lowering movements. Figure 3The key parts shown are as follows. The lifting motor 32, the fixed nut seat 34, the support nut seat 35, and the lifting slide rail 36 are fixed on the lifting support frame 31. The lifting motor 32 is the power output of the lifting mechanism 3. The power is transmitted to the fork base 44 through the screw rod 33 to drive it to rise and fall. The fixed nut seat 34 and the support nut seat 35 play a supporting and fixing role on the screw rod 33. The lifting slide rail 36 serves as a guide mechanism to prevent the fork base 44 from tilting during lifting and falling. The lifting support frame 31 is fixed on the translation frame 21. When the lifting motor 32 drives the screw rod 33 to rotate, the screw rod 33 and the lifting nut seat 42 are matched with each other to convert the rotational motion of the screw rod 33 into the lifting and falling linear motion of the fork support frame 41. When the entire mechanism is in a descending state, the rotating fork mechanism 4 is at the lowest position. When the goods need to be lifted, the lifting mechanism 3 rises and drives the fork base 44 to rise to the highest point. The lifting mechanism 3 has a compact structure and can effectively save the height of the equipment. The entire lifting mechanism 3 can move horizontally with the horizontal traction mechanism 2 to transport the goods to the mother pallet of the conveyor line.

[0033] like Figure 4 As shown, the rotary fork mechanism 4 includes a fork base 44, a fork motor 45, a lever 46, and a telescopic plug plate 47. The fork motor 45 is connected to the fork base 44.

The guide column 461 is movably connected in the telescopic guide hole 471. The fork motor 45 drives the lever 46 to rotate so that the guide column 461 rotates around the circumference. The lever 46 converts the circular motion of the lever 46 into the linear motion of the telescopic plug plate 47 by cooperating with the telescopic guide hole 471, thereby realizing the telescopic motion of the telescopic plug plate 47 relative to the fork base 44. The fork motor 45 is preferably a reduction motor.

[0034] The rotary fork mechanism 4 further includes a telescopic slide rail 48 and a telescopic slider 49 . The telescopic slide rail 48 is fixed on the fork base 44 , and the telescopic slider 49 is fixed on the telescopic plug plate 47 . The telescopic slider 49 is cooperatively connected with the telescopic slide rail 48 .

[0035] The rotating fork mechanism 4 drives the fork rod to rotate through the reduction motor, and cooperates with the linear guide rail 25 to guide the fork arm to extend and retract. Figure 4 The key parts are shown in the figure. The fork motor 45 provides power to drive the lever 46 to rotate, the telescopic slide rail 48 limits and guides the telescopic plug plate 47, the lever 46 pushes the telescopic plug plate 47 to make linear reciprocating motion, and the fork base 44 supports and fixes the entire mechanism. At the same time, the fork base 44 is connected to the lifting mechanism 3, so that the lifting mechanism 3 can drive the rotating fork mechanism 4 to rise and fall. The mechanism is simple and practical in structure, high in telescopic efficiency, and suitable for a variety of pallets.
