Technical Field

[0001] The present application relates to the technical field of warehousing logistics, and in particular to an elevator for multi-directional cargo entry and exit. Background Art

[0002] The three-dimensional shelves realize the multi-layer storage of goods, which improves the space utilization rate of warehouses in warehousing logistics. When storing goods on the three-dimensional shelves, it is necessary to use a hoist to realize the circulation of goods between different layers.

[0003] The existing elevator connects the logistics conveying equipment or cargo storage cavity on different layers of the three-dimensional shelf through the two sides of the liftable platform directly opposite. The logistics conveying equipment or cargo storage cavity transports the goods to the liftable platform. The liftable platform drives the goods to be lifted and lowered, and the goods are transported and placed on the logistics conveying equipment or cargo storage cavity on another layer of the three-dimensional shelf, so that the goods can be circulated or directly stored between different layers.

[0004] The elevator transfers goods between the two sides facing it, which reduces the docking effect between the elevator and the three-dimensional shelf, which is not conducive to fully utilizing the storage advantages of the three-dimensional shelf. Summary of the invention

[0005] In order to improve the docking effect between the elevator and the three-dimensional shelf, the present application provides an elevator for multi-directional entry and exit of goods.

[0006] The present application provides a multi-directional cargo elevator, which adopts the following technical solution: A multi-directional cargo elevator, comprising: The frame is provided with an even number of inlet and outlet ports along the circumference, and the number of the inlet and outlet ports is at least four, and all the inlet and outlet ports are arranged opposite to each other in pairs; A lifting platform, slidably arranged in the frame; There are at least four shipping components, all of which are located on the lifting platform. The shipping components correspond to the cargo inlet and outlet one by one, and include a push rod, a cargo pushing part, and a swinging part. Wherein, one end of the push rod is slidably arranged in a cargo pushing chute provided on the lifting platform, and the sliding direction is consistent with the direction of cargo in and out of the cargo inlet and outlet; The pushing part is arranged on the lifting platform and is used to drive the push rod to slide relative to the lifting platform; The swinging part is connected between the push rod and the cargo pushing part, and is used to make the push rod in a swinging state with the cargo pushing part when it is located at the end of the cargo pushing chute, and is used to make the push rod in a fixed state with the cargo pushing part when it slides in the cargo pushing chute.

[0007] By adopting the above technical scheme, more than four inlet and outlet ports on the frame increase the docking interface between the elevator and the three-dimensional shelf, enhance the docking performance between the elevator and the three-dimensional shelf, and the logistics conveying equipment or the cargo storage cavity can transport the goods from any inlet and outlet to the lifting platform. The swing part enables the push rod to swing relative to the pushing part when it is at the end of the pushing chute, so that the goods can enter the lifting platform by pushing the push rod to swing. When unloading is required, the pushing part can push the push rod to slide along the pushing chute, and under the action of the swing part, the push rod and the pushing part are in a fixed state, and the push rod can push the goods to slide out of the lifting platform, so that the goods can be transported from any inlet and outlet to the logistics conveying equipment or the cargo storage cavity, so that the elevator can have multiple interfaces to arbitrarily input and output goods, thereby improving the docking effect between the elevator and the three-dimensional shelf.

[0008] Optionally, the shipping components corresponding to each pair of opposing loading and unloading ports are located in the same cargo pushing chute, and the cargo pushing part includes a slider, which is slidably arranged in a driving chute opened on the side wall of the cargo pushing chute, and is connected to the push rod through the swing part, and a first electromagnet is fixedly provided on the side wall on which the slider and the end of the driving chute are close to each other, and a second electromagnet is fixedly provided on the end of the slider away from the first electromagnet.

[0009] By adopting the above technical solution, the two first electromagnets at the ends of the slider and the driving slide groove can drive the slider to slide back and forth through magnetic thrust and magnetic attraction. At the same time, the second electromagnet between the two sliders can assist the slider to slide back and forth through magnetic thrust and magnetic attraction, so that the slider can easily drive the push rod to move along the driving slide groove, so that the push rod can push the goods out of the lifting platform, thereby making it easy for the goods to be moved out of the lifting platform from any entry and exit port.

[0010] Optionally, the swinging part includes a swinging plate and a return spring. The swinging plate is penetrated through a portion of the slider that is opposite to the cargo pushing chute and is rotatably connected to the slider. The push rod is fixedly penetrated through the swinging plate. The return spring is arranged between the push rod and the slider and is used to drive the push rod to return to its original position after swinging.

[0011] By adopting the above technical solution, the push rod can swing relative to the slider through the swing plate, and under the elastic force of the reset spring, the push rod can automatically reset after swinging, so that the goods can easily push the push rod to swing, so that the push rod is not easy to affect the movement of the goods in or out of the lifting platform under the condition that it can push the goods.

[0012] Optionally, the swinging part also includes a fixed rod, which is fixed to one end of the push rod located in the cargo pushing chute, and a fixed chute for sliding the end of the fixed rod is provided on the side wall of the cargo pushing chute, and a swinging groove for swinging the fixed rod is provided at the end.

[0013] By adopting the above technical solution, when the push rod is located at the end of the cargo pushing chute, the fixed rod can swing with the push rod in the swinging groove, so that the fixed rod is not easy to affect the swing of the push rod; when the push rod drives the fixed rod to slide into the fixed chute, under the restriction of the fixed chute, the push rod is difficult to swing, so that the push rod can be relatively fixed to the sliding block when pushing the cargo.

[0014] Optionally, a plurality of bull's eye wheels are fixedly provided on the lifting platform.

[0015] By adopting the above technical solution, the goods can be placed on the bull's eye wheels after being moved to the lifting platform, thereby reducing the friction between the goods and the lifting platform, making it easy to move the goods into or out of the lifting platform.

[0016] Optionally, one end of the push rod located outside the cargo pushing chute is symmetrically rotatably connected to two transition rollers, and the axial directions of the two transition rollers are perpendicular to the sliding direction of the push rod.

[0017] By adopting the above technical solution, the two transition rollers on the push rod can cooperate with the push rod to stably push the goods to move, and on the other hand, when the goods are moved in or out of the lifting platform, the transition rollers swing with the push rod, and the rotatable transition rollers can move the goods to the bull's eye wheel in a rolling manner, thereby making it easy to move the goods to the bull's eye wheel, and during the movement process, the transition rollers can play a connecting role.

[0018] Optionally, a control component is provided between each pair of the two groups of the delivery components corresponding to the opposite delivery ports, and the control component is used to control the swing direction of the push rods in the two groups of the delivery components when they are located at the ends of the cargo pushing chute; When the push rods of the two groups of the delivery components are both located at the ends of the cargo pushing chute, the control component controls the swing directions of the two push rods to only be toward the inner side of the lifting platform; When the push rod of one group of the shipping components slides and the push rod of the other group of the shipping components is located at the end of the cargo pushing chute, the control component controls the swinging direction of the push rod located at the end of the cargo pushing chute to be in a free state during the initial sliding stage of the sliding push rod.

[0019] By adopting the above technical scheme, the control component can control the swinging direction of the push rod at the end of the cargo pushing chute; when there is no need to push the cargo, the control component controls the push rod to swing only toward the inside of the lifting platform, so that the cargo is easy to move into the lifting platform and difficult to move out of the lifting platform, so that the cargo is not easy to slip when following the lifting platform; when it is necessary to push the cargo out of the lifting platform, the push rod in the cargo moving out direction can swing freely under the control of the control component, so that the cargo is not easily blocked by the push rod in its own moving out direction when moving out of the lifting platform.

[0020] Optionally, the control component includes two control units, wherein one group of the delivery components controls the swing direction of the push rods in another group of the delivery components through one of the control units, and the other group of the delivery components controls the swing direction of the push rods in one group of the delivery components through another control unit; In one of the control units, the control unit includes a driving cylinder, a control cylinder, a limit block and a control block; The driving oil cylinder is embedded in the side wall of the driving slide and is located at one end of the driving slide close to the slider in one group of the shipping components. The two ends of the slider close to the driving oil cylinder are inclined in a direction away from each other, and the movable end of the driving oil cylinder abuts against the inclined surface of the slider close to the center of the lifting platform. The control oil cylinder is embedded on the slide block in another group of the delivery components and is located on one side of the swing plate close to the center of the lifting platform; The limit block is fixed on the movable end of the control oil cylinder and is slidably arranged in the control slide groove provided on the slide block. The side of the limit block close to the swing plate is in an arc shape and fits with the side wall of the swing plate. The control block is fixedly arranged on a side of the swing plate close to the fixed rod, and abuts against an end of the limit block close to the fixed rod; Hydraulic oil flows between the rodless chamber of the driving oil cylinder and the rod chamber of the control oil cylinder through the control oil pipe.

[0021] By adopting the above technical solution, the two control units respectively realize the control of the swing direction of the push rods in the two groups of shipping components. When one of the push rods pushes the goods out of the lifting platform, the swing direction of the other push rod located in the direction of the goods moving out can swing freely.

[0022] When one of the sliders drives the push rod to push the goods, the slider squeezes the active end of the driving cylinder through its own inclined surface to contract, so that the hydraulic oil in the rodless chamber of the driving cylinder flows into the rod chamber of the control cylinder through the control oil pipe. The hydraulic oil pushes the active end of the control cylinder to contract, and the control cylinder drives the limit block to slide away from the swing plate, and provides sliding space for the control block on the swing plate, so that the control block can slide into the control slide groove, thereby allowing the push rod to swing in a direction away from the center of the lifting platform.

[0023] Optionally, a control spring for driving the limit block to reset is arranged in the rodless cavity of the control oil cylinder.

[0024] By adopting the above technical solution, when the slider is reset, the control spring can drive the control cylinder to extend through its own elastic force, and the control cylinder drives the limit block to fit again with the swing plate, so that the limit block limits the control block again.

[0025] Optionally, a lifting assembly is arranged between the lifting platform and the frame, and the lifting assembly includes a lead screw, a lifting gear, a driving gear and a lifting motor. At least two lead screws are provided and are threaded through the edge of the lifting platform. The lead screw is rotatably connected to the frame. At least two lifting gears are provided and correspond one-to-one to the lead screws. The lifting gear is coaxially fixed to the end of the lead screw. The driving gear is meshed with all the lifting gears and is rotatably connected to the frame. The lifting motor is fixedly connected to the frame, and the output shaft of the lifting motor is coaxially fixed to the driving gear.

[0026] By adopting the above technical solution, the lifting motor drives the driving gear to rotate, the driving gear drives all the lifting gears to rotate, the lifting gear drives the lead screw to rotate, and the lead screw drives the lifting platform to lift and lower, thereby relying on the lead screw drive method to make it easy to move goods into or out of the lifting platform from any entry and exit port.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: By opening more than four inlet and outlet ports and setting push rods, sliders, swing plates and fixed rods, goods can be moved into or out of the lifting platform from any inlet and outlet port, thereby improving the docking effect between the elevator and the three-dimensional shelf; By setting bull's eye wheels and transition rollers, the goods can be easily slid in or out of the lifting platform; By arranging a driving oil cylinder, a control oil cylinder, a limit block and a control block, the swing direction of the push rod located in the direction of moving out the goods can be easily automatically regulated.
