Description
Technical Field
[0001] The utility model relates to the technical field of transportation devices, in particular to a lifting and transferring machine. Background Art
[0002] The lifting and transferring machine is a key device used to change the direction of goods conveying in the automated logistics system. It is mainly used to send goods from the branch line to the main line or from the main line to the branch line, or for right-angle steering. This equipment has the characteristics of large carrying capacity, simple structure, stability and reliability. For different use environments, there are many forms of common lifting and transferring machines, such as cylinder lifting mechanism, screw lifting mechanism, scissor-type lifting mechanism, connecting rod lifting mechanism, single cam lifting mechanism, etc. The cylinder lifting mechanism is easy to shake and unstable when the workpiece range (i.e., lifting table) is relatively large and the lifting height is relatively large. Moreover, due to the limitation of the cylinder output force, the lifting table (including the weight of the workpiece) cannot be too heavy, that is, it cannot be used for lifting operations of heavy workpieces. The screw lifting mechanism has high processing and installation precision requirements and high cost, and is not suitable for occasions where cost control is required. The scissor-type lifting mechanism needs to be equipped with a hydraulic system to accurately control the lifting stroke, which increases the cost and requires more installation space. In addition, the joint shaft is subjected to great stress, which leads to great wear and high maintenance costs. The connecting rod lifting mechanism has a complex structure, complex torque transmission, and low energy efficiency, and is only suitable for light loads and small occasions. For the single cam lifting mechanism, when the lifting range (i.e., the lifting table) is relatively large, since there is only a cam in the middle of the equipment, if it is an irregular workpiece, the center of gravity of the lifting table is greatly offset, and the lifting is unstable, which is manifested in the inaccurate control of the distance from the lifting to the high position and the step of the front and rear conveyor docking. Therefore, there is an urgent need for a lifting and transferring machine that is suitable for large and heavy workpieces and has a more stable lifting. Utility Model Content

[0026] It is easily understandable that, according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following specific embodiments and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.
[0027] According to Figures 1 to 2 As shown, the present utility model provides a lifting and transferring machine 100, which includes a fixed support frame 10, a lifting frame 20, a transmission mechanism 30, a driving mechanism 40, a guiding mechanism 50, and a conveying mechanism 60.
[0028] Among them, the fixed support frame 10 is adapted to be supported on the ground. The lifting frame 20 is movably arranged on the fixed support frame 10 along the up and down direction, and limiting grooves 21 are arranged around the bottom of the lifting frame 20. The transmission mechanism 30 includes a pair of transmission shafts 31 and eccentric wheels 32 fixedly arranged at both ends of the pair of transmission shafts 31. The pair of transmission shafts 31 are spaced apart and arranged on the fixed support frame 10 and span across the bottom of the lifting frame 20. A rotating wheel 33 is arranged on the eccentric wheel 32 through a rotating shaft, and the rotating wheel 33 is movably matched with the limiting groove 21. The driving mechanism 40 is configured to be adapted to drive the pair of transmission shafts 31 to rotate synchronously, so that the lifting frame 20 moves relative to the fixed support frame 10 along the up and down direction. The guiding mechanism 50 is configured to be adapted to guide the lifting frame 20 in the up and down direction. The conveying mechanism 60 is arranged on the lifting frame 20 and is configured to be adapted to convey the workpiece supported on the lifting frame 20.
[0029] Since there are rotating wheels 33 movably matched with the limiting grooves 21 at the four corners of the lifting frame 20, the rotating wheels 33 serve as both the support points of the lifting frame 20 and the force transmission points for the lifting power of the lifting frame 20. In this way, even if the range of the lifting frame 20 is relatively large or the center of gravity of the lifting frame 20 is offset, very smooth movement can be achieved. It is suitable for the lifting and transferring operations of large and heavy workpieces. By providing the guiding mechanism 50 to provide the guiding effect for the lifting frame 20 during lifting, it is avoided that the lifting frame 20 is offset, tilted, etc. during the lifting process, so that the lifting frame 20 can lift and convey the workpiece more smoothly, and the smoothness is better.
[0030] Specifically, in the present embodiment, a pair of transmission shafts 31 are arranged on the fixed support frame 10 at intervals along a first direction, and a pair of transmission shafts 31 extend along a second direction perpendicular to the first direction, and the conveying mechanism 60 is constructed to be suitable for conveying the workpiece supported on the lifting frame 20 along the first direction. Among them, the first direction is a direction extending along the front and back, and the second direction is a direction extending along the left and right. The layout structure in which the transmission shaft 31 and the conveying mechanism 60 are perpendicular to each other can make the lifting frame 20 more balanced in force and obtain better stability. In other embodiments, the first direction can also be a direction extending along the left and right, and the second direction can also be a direction extending along the front and back. Alternatively, the extension direction of the transmission shaft 31 can also be arranged at an angle or in parallel with the conveying direction of the conveying mechanism 60, without specific limitation.
[0031] according to Figure 2 As shown, the driving mechanism 40 includes a driving motor 41, a driving wheel 42 drivingly connected to the driving motor 41, a driven wheel 43 mounted on a pair of transmission shafts 31, and a synchronous transmission member (not shown in the figure) connected between the driving wheel 42 and the driven wheel 43. Specifically in this embodiment, the driving motor 41 can be a reduction motor, the driving wheel 42 and the driven wheel 43 can be sprockets respectively, and the synchronous transmission member can also be a synchronous chain accordingly. In other embodiments, the driving wheel 42 and the driven wheel 43 can also be pulleys, synchronous wheels, etc., and the synchronous transmission member can also be a belt, a toothed belt, etc., without specific limitation.
[0032] By using a reduction motor as the power, the weight of the workpiece being transported can be very large, and it is suitable for both light-load and heavy-load occasions.
[0033] A synchronous transmission member is used to drive a pair of transmission shafts 31 to rotate synchronously, so that a driving motor 41 drives two transmission shafts 31 to rotate synchronously, which can not only simplify the driving mechanism 40, but also ensure that the lifting frame 20 can be lifted and moved synchronously in the up and down directions relative to the fixed support frame 10.
[0034] The driving motor 41 is fixedly supported on the ground, and the driving motor 41 is connected to a driving shaft 44, and the driving wheel 42 is fixedly mounted on the driving shaft 44. Since the driving motor 41 is generally large in size, it will take up a large space if it is directly mounted on the fixed support frame 10. Such a configuration can make the space utilization rate on the fixed support frame 10 higher. In other embodiments, the driving motor 41 can also be fixedly mounted on the fixed support frame 10, which is not specifically limited.
[0035] The guiding mechanism 50 includes a guiding rod 51 and a pair of guiding wheels 52. The pair of guiding wheels 52 are installed on the fixed support frame 10. One end of the guiding rod 51 is fixedly arranged on the lifting frame 20, and the other end of the guiding rod 51 extends downward and is slidably engaged between the pair of guiding wheels 52. When the lifting frame 20 is driven to move up and down, the guiding rod 51 on the lifting frame 20 is slidably engaged with the pair of guiding wheels 52 on the fixed support frame 10, preventing the lifting frame 20 from shifting, tilting, etc. during the lifting movement.
[0036] Due to the provision of the guiding mechanism 50, the lifting frame 20 will not tilt when the workpiece is just introduced into the transfer machine. During the jacking process, it further ensures that the lifting movement trajectory is vertical movement without lateral yaw, which can guarantee the smooth movement of the transfer machine when docking with the front and rear conveyor belt devices on the production line.
[0037] There are two guiding mechanisms 50, and the two guiding mechanisms 50 are arranged on the opposite side parts of the fixed support frame 10. In other embodiments, only one guiding mechanism 50 may be provided or guiding mechanisms 50 may be arranged around the lifting frame 20, and there is no specific limitation.
[0038] The conveying mechanism 60 includes a conveying shaft 61 rotatably arranged on the lifting frame 20, a conveying wheel 62 installed on the conveying shaft 61, a follower wheel 63 rotatably arranged on the lifting frame 20, a transmission member (not shown in the figure) connected between the conveying wheel 62 and the follower wheel 63, and a conveying motor 64 arranged on the lifting frame 20 and drivingly connected to the conveying shaft 61. In this embodiment, the conveying wheel 62 and the follower wheel 63 can be sprockets, and the transmission member can correspondingly adopt a synchronous chain. In other embodiments, the conveying wheel 62 and the follower wheel 63 can also adopt pulley wheels, synchronous wheels, and the transmission member can also adopt a belt, toothed belt, etc., and there is no specific limitation.
[0039] In other embodiments, the conveying mechanism 60 can also adopt a roller conveying structure, and there is no specific limitation.
[0040] The conveying mechanism 60 further includes limit support wings 65 arranged at the opposite ends of the lifting frame 20. A conveying channel 66 is formed between the two limit support wings 65, enabling the conveying mechanism 60 to convey workpieces with larger volume and weight.
[0041] The technical scope of the present utility model is not limited to the content in the above specification. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the protection scope of the present utility model.
