Description

Technical Field

[0001] This utility model relates to the field of logistics and warehousing technology, specifically to a fully automatic rack and pinion reciprocating lifting device for goods. Background Technology

[0002] In existing logistics and warehousing systems, multi-level conveyor lines are typically used to improve cargo handling efficiency, making full use of vertical space and enabling efficient transfer of goods between different floors or areas. However, in multi-level conveyor systems, pallet changing operations have become a critical technical aspect.

[0003] Currently, the pallet-changing equipment used in logistics warehousing systems is mostly semi-automatic or fully automatic reciprocating pallet-changing elevators. While these elevators achieve vertical pallet transport to some extent, they still have many shortcomings.

[0004] First, semi-automatic pallet-changing elevators require manual operation to complete the pallet-changing process. This not only increases labor costs but also reduces the automation level of the entire logistics system. Manual operation can also lead to inconsistencies, affecting conveying efficiency and accuracy. Furthermore, manual operation poses certain safety hazards, such as potential injury to personnel or damage to goods due to improper operation.

[0005] Secondly, while fully automatic reciprocating floor-changing elevators achieve a certain degree of automation, some problems still exist in practical applications. For example, the control system of these elevators may not be intelligent enough to flexibly adjust the operating speed and stopping position according to actual needs. Furthermore, due to structural design limitations, these elevators may generate significant impact and noise during floor-changing, potentially damaging the equipment and goods.

[0039] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] like Figures 1 to 4 As shown in the first aspect embodiment of the present invention, a fully automatic rack and pinion reciprocating lifting device for goods includes an outer frame 1. Inside the outer frame 1, a car conveying device 2, a counterweight device 3, a sensing device 4, and a buffer device 5 are respectively arranged. The car conveying device 2 can carry goods and move up and down autonomously inside the outer frame 1. The counterweight device 3 is connected to the car conveying device 2 and can follow the car conveying device 2 to move up and down in the opposite direction. The sensing device 4 has several sensing components and can monitor and control the position of the car conveying device 2. The buffer device 5 is installed at the bottom of the outer frame 1 and can offset the impact force generated when the car conveying device 2 descends to the lowest position.

[0041] The car conveying device 2 includes rails 21 symmetrically installed on both sides of the outer frame 1, and several toothed plates 22 symmetrically installed at the corners of the outer frame 1. The car 23 is slidably connected between the rails 21. A motor drive device 25 is installed at the bottom of the car 23. The motor drive device 25 can provide the car 23 with the power to lift and lower. A conveying device 26 is installed and fixed inside the car 23. The conveying device 26 is preferably a double-speed chain. When picking up and putting down goods, the double-speed chain plays the role of conveying the pallet 27 and the goods. The specific structure and principle of the double-speed chain are existing known technologies and will not be described in detail here. The pallet 27 for carrying goods is placed on the conveying end of the conveying device 26.

[0042] Guide wheel sets 24 are installed on both sides of the car 23. The guide wheel sets 24 are engaged with the outside of the track 21. During the lifting and lowering process, the guide wheel sets 24 roll along the direction of the track 21, which can greatly improve the stability of the car 23 during the lifting and lowering process.

[0043] The motor transmission device 25 includes a drive motor 251 installed at the bottom of the car 23 and several reducers 252. Each reducer 252 has one power input end and two power output ends. The drive end of the drive motor 251 is connected and fixed to the power input end of one of the reducers 252. The power output ends and power input ends of two adjacent reducers 252 are connected by a transmission shaft 254. A gear 253 is installed on the other power output end of the reducer 252. The gear 253 meshes with the gear plate 22.

[0044] The counterweight device 3 includes a second track 31 symmetrically installed on the side of the outer frame 1, and several sprockets 32 installed on the top of the outer frame 1. The counterweight frame body 33 is slidably connected inside the second track 31. Several counterweight blocks 34 are stacked inside the counterweight frame body 33. The top of the counterweight frame body 33 is connected to a chain 35. The end of the chain 35 passes around several sprockets 32 and is connected to the top of the car 23.

[0045] The sensing device 4 includes, from top to bottom, an upper limit switch 41, an upper position photoelectric sensor 42, an upper trigger deceleration photoelectric sensor 43, a lower trigger deceleration photoelectric sensor 44, a lower position photoelectric sensor 45, and a lower limit switch 46, all mounted on the outer frame 1. The upper position photoelectric sensor 42 controls the motor drive device 25 to shut down when the car conveyor 2 reaches the loading docking position; the lower position photoelectric sensor 45 controls the motor drive device 25 to shut down when the car conveyor 2 reaches the unloading docking position; the upper trigger deceleration photoelectric sensor 43 and the lower trigger deceleration photoelectric sensor 44 both control the motor drive device 25 to decelerate; the upper limit switch 41 controls the motor drive device 25 to shut down when the car conveyor 2 exceeds the loading docking position; and the lower limit switch 46 controls the motor drive device 25 to shut down when the car conveyor 2 exceeds the unloading docking position.

[0046] The buffer device 5 consists of a base and several dampers. When the car conveyor 2 descends to its lowest position, the bottom of the car conveyor 2 will abut against the dampers. Through the combined action of several dampers, the impact force is reduced.

[0047] When the equipment is working, several drive shafts 254 drive motors 251 to drive several reducers 252 to work synchronously, thereby causing several gears 253 to rotate synchronously. At this time, the gears 253 will rotate and move along the direction of the toothed plate 22, so that the car 23, motor drive device 25, conveying device 26, and pallet 27 are raised and lowered synchronously. During the process of the car 23 rising and falling along the track 21, because of the counterweight device 3, when the car 23 rises, the two chains 35 are supported by the counterweight frame 33 and the counterweight. The entire block 34 is dragged along and moves. Similarly, when the car 23 descends, the two chains 35 are dragged along and move. The corresponding counterweight frame 33 and counterweight block 34 also rise along with it. When the car 23 reaches each height, the upper limit switch 41, the upper position photoelectric sensor 42, the upper trigger deceleration photoelectric sensor 43, the lower trigger deceleration photoelectric sensor 44, the lower position photoelectric sensor 45, and the lower limit switch 46 will all monitor it. And according to their positions, they can also adjust the motor transmission device 25.

[0048] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
