Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo conveying technology, specifically a lifting and indexing conveyor. Background Technology
[0002] Existing rotary conveyors are prone to misalignment during rotation, resulting in inaccurate docking of conveyor lines and potential damage to products; furthermore, they can only be used for docking between two conveyor lines at the same height, greatly limiting their application range.
[0003] The utility model patent with authorization announcement number CN209480660U discloses a precision positioning rotary lifting conveyor, comprising a motor cabinet containing a rotary motor, a lower base plate on the motor cabinet, and a divider on the lower base plate; an upper base plate on the upper end of the divider, and a sliding groove at the bottom of the upper base plate; a frame and a movable frame on the upper base plate, with a conveying guide bar and a conveying motor on the frame, and a movable roller on the movable frame; two conveying guide bars are provided, connected at one end by a drive shaft; a conveying motor is located at one end of the conveying guide bar and connected to a conveying sprocket; one end of the drive shaft is connected to a driven conveying wheel, and a synchronous sprocket is provided between the drive shaft and the conveying guide bar; two synchronous pulleys are provided on the drive shaft and connected to a transition plate; a tilting shaft is provided between the two transition plates and connected to a tilting cylinder; a lifting cylinder and a guide column are provided on the upper base plate, and the lifting cylinder and guide column are connected to the movable frame.
[0004] However, existing conveyors achieve lifting and lowering through lifting cylinders and guide columns, but lack a dedicated load-bearing structure designed for heavy-load palletized goods. When conveying loads exceeding 2 tons, the following problems may occur: insufficient output force of the lifting cylinder may cause lifting and lowering to stall, or the guide columns may bend and deform due to excessive load, affecting lifting accuracy. The connection structure between the tilting cylinder and the tilting shaft may wobble during heavy-load rotation, causing goods to shift during rotation and affecting docking accuracy. Furthermore, existing conveyors rely on dividers and rotary motors for rotation, but lack high-precision position detection devices, making it impossible to dynamically adjust the angle according to actual needs, and lacking real-time angle feedback. This may lead to accumulated rotational deviations due to divider wear. Goods positioning relies solely on conveyor guides and moving rollers, without goods arrival detection sensors, which can easily result in lifting starting before the goods are fully in place, leading to mechanical gear failure or goods tipping over. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a lifting and indexing conveyor that solves the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting and indexing conveyor, comprising:

[0015] Preferably, the cam mechanism includes a lifting reduction motor, a drive shaft, a driven sprocket, and a chain. The lifting reduction motor drives the drive shaft to rotate.

[0018] Beneficial effects
[0019] This utility model provides a lifting and indexing conveyor. Compared with the prior art, it has the following advantages:
[0020] 1. This lifting and indexing conveyor integrates the traditional "conveyor-lifting-indexing" function, which requires 2-3 pieces of equipment, into a single device through the integrated design of the conveying mechanism, gear-rack mechanism, cam mechanism, and rotary support mechanism. This eliminates positioning errors when multiple devices are connected and ensures the positional accuracy of goods during lifting and indexing by real-time calibration of the actions of each mechanism through detection devices. This avoids damage to goods or interruption of the process due to equipment mismatch.
[0021] 2. This lifting and indexing conveyor uses a hybrid connection method with a cam mechanism to ensure reduced horizontality error of the cross-lifting support, avoiding the support tilting caused by traditional double-key connections. It adapts to smooth lifting under heavy loads. At the same time, it automatically matches the power and speed of the reduction motor according to the weight of the goods and the lifting height, and monitors the lifting height in real time with a proximity switch to achieve load adaptive control, significantly improving the stability and accuracy of heavy load transfer. Compared with existing technologies, it is more suitable for automated handling of heavy goods. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-3 This utility model provides two technical solutions:
[0028] First embodiment: A lifting and indexing conveyor, including a conveying mechanism, a gear-rack mechanism, a cam mechanism, a rotary support mechanism, a guiding mechanism, a cross lifting bracket and a detection device.
[0029] The conveying mechanism is used to transport heavy-load goods. The conveying mechanism includes a conveying roller 8 and a conveying geared motor 3. The conveying geared motor 3 is driven and connected to the conveying roller 8. The conveying geared motor 3 is connected to the conveying roller 8 through a sprocket 15, a chain 10 or a gear transmission system. The motor power is intelligently matched according to the weight of the goods and the transportation speed requirements to ensure the smooth transportation of heavy-load goods.
[0030] The guiding mechanism includes baffle guide structures set on both sides of the conveying mechanism. They are made of high-strength steel or polyurethane material and are used to transport goods to the top of the cross lifting support and to limit their movement laterally. The spacing can be adjusted by screws to accommodate palletized goods of different sizes and prevent goods from shifting or tipping over during transportation.
[0031] The gear-rack mechanism includes a geared motor 4, a gear 13, and a rack 14. The geared motor 4 drives the gear 13 to rotate and meshes with the rack 14 for transmission. The baffle connected to the rack 14 moves up and down within the path defined by the linear guide rail or slide of the guide mechanism to form a mechanical stop for the cargo. The geared motor 4 drives the gear 13 to rotate, and the rack 14 meshing with the gear 13 moves linearly in the vertical direction, causing the connected baffle to rise or fall. The surface of the baffle is covered with an anti-slip rubber layer. When rising, it contacts the bottom or side of the cargo to form a rigid stop and prevent the cargo from moving. When falling, it disengages from the cargo and releases the limit. The guide mechanism uses a linear guide rail or slide to cooperate with the rack 14 to avoid the risk of jamming due to tilting.
[0032] The cam mechanism includes a lifting reduction motor 1, a drive shaft 16, a driven sprocket, and a chain 10. The lifting reduction motor 1 drives the drive shaft 16 to rotate. The drive shaft 16 is connected to the driven sprocket via a key connection and a shrink sleeve connection, respectively. The chain 10 transmits torque to the cross lifting bracket to lift the goods to a preset height. The key connection provides stable torque transmission, and the shrink sleeve connection can finely adjust the coaxiality, solving the problem of horizontal deviation of the bracket caused by traditional double key connections and ensuring that the four ends of the cross lifting bracket are raised and lowered synchronously.
[0033] The slewing support mechanism includes a rotary gear motor 2, a drive gear 6, and a slewing support 7. The rotary gear motor 2 drives the drive gear 6 to mesh with the slewing support 7. The slewing support 7 is connected to the cross lifting bracket and is used to drive the cross lifting bracket and the cargo to rotate 90° or 180°. The rotary gear motor 2 drives the drive gear 6 to mesh with the internal or external gear ring of the slewing support 7, thereby driving the slewing support 7 to rotate. The slewing support 7 adopts high-precision crossed roller bearings or four-point contact ball bearings, which have strong load-bearing capacity and ensure the stability of heavy-load cargo rotation.
[0034] The second implementation differs from the first implementation in that the detection device includes a through-beam photoelectric sensor 12 and a proximity switch 11. The through-beam photoelectric sensor 12 is used to detect the position of the goods and trigger the action of the conveying mechanism. The proximity switch 11 is used to detect the lifting height and rotation angle of the goods to control the start and stop of each mechanism. The through-beam photoelectric sensor 12 is installed at key positions such as the inlet end of the conveying roller 8 and above the cross lifting bracket. It uses the infrared through-beam principle to detect whether the goods are in place or deviated, and triggers the start and stop of the conveying reduction motor 3 and the action of the gear-rack mechanism in real time. The proximity switch 11 includes a lifting height detection switch and a rotation angle detection switch. Through electromagnetic induction or photoelectric principle, it accurately feeds back the height of the bracket and the rotation angle to ensure that each mechanism starts and stops according to the preset logic.
[0035] During operation, the heavy-load goods to be transferred are placed onto the conveyor rollers 8 of the conveyor by an external conveying device. Through-beam photoelectric sensors 12 located on both sides of rollers 8 detect the goods' position in real time. Once the goods have fully entered the conveying area, the conveyor reduction motor 3 starts, driving the conveyor rollers 8 to rotate via sprockets 15 and chains 10, smoothly transporting the goods directly above the cross-shaped lifting support. During this process, the guide mechanisms (baffle guide structures) on both sides of the conveying mechanism laterally limit the goods, ensuring they are transported in a straight line and preventing deviation. After the goods reach above the cross-shaped lifting support, the through-beam photoelectric sensors 12 detect the arrival signal, triggering the reduction motor 4 of the gear-rack mechanism to start. The reduction motor 4 drives the gear 13 to rotate, and the rack 14 meshing with the gear 13 rises vertically along the linear guide rail of the guide mechanism, causing the connected baffles to rise synchronously, forming mechanical stops on both sides of the goods, preventing further movement and completing the positioning.
[0036] At this point, the goods are accurately secured within the bearing area of the cross-shaped lifting support. The lifting reduction motor 1 transmits power to the drive shaft 16 via gears and chains, based on the weight of the goods and the preset lifting height. Both ends of the drive shaft 16 are connected to the driven sprockets via key connections and expansion sleeves, respectively. This hybrid connection method avoids the horizontal deviation problem that may occur with traditional double-key connections, ensuring smooth lifting of the support. When the cross-shaped lifting support lifts the goods to the preset height, the proximity switch 11 detects the arrival signal, the lifting reduction motor 1 stops working, and the goods are suspended and lifted, detaching from the conveyor roller 8, preparing for the indexing operation. The indexing reduction motor 2 starts, driving the slewing support 7 to rotate via the drive gear 6, causing the cross-shaped lifting support and the goods to rotate synchronously.
[0037] The proximity switch 11 monitors the rotation angle in real time. When the load is detected to have rotated to 90° or 180° (preset angle), the rotation reduction motor 2 stops, and the slewing support 7 locks its current position. During this process, the slewing support mechanism provides stable rotational support, ensuring the balance and accuracy of the heavy load during rotation. After rotation is complete, the lifting reduction motor 1 reverses its rotation, driving the cross lifting bracket to slowly descend until the load smoothly falls back onto the conveyor roller 8. Simultaneously, the gear-rack mechanism's reduction motor 4 starts in reverse, and the rack 14 drives the baffle to descend and retract to its mechanical stop position.
[0038] The conveyor geared motor 3 restarts, driving the roller 8 to transport the rotated goods to the next process, completing the entire transfer process. The through-beam photoelectric sensor 12 monitors the goods' position throughout the process, triggering the start and stop of each mechanism; the proximity switch 11 accurately detects the lifting height and rotation angle, ensuring the accuracy of each action node. The control system intelligently matches the output power of the geared motors required for conveying, lifting, and rotation based on parameters such as goods weight and running speed, achieving adaptive adjustment of the equipment. The entire process, through the coordination of mechanical mechanisms and detection devices, avoids deviations caused by multiple devices working together, improving transfer efficiency and stability.
