[0001] The utility model relates to the technical field of pallet lifting, in particular to a pallet lifting and transferring device. Background Art

[0002] The pallet lifting and transferring machine is mainly composed of an upper transferring component (roller conveyor) and a lower lifting part. The structural form of the transferring component is the same as that of the roller conveyor. It is mainly used to change the direction of cargo transportation, and to send or move cargo such as car seats, tires, bumpers, etc. into or out of the main conveyor line, thereby realizing automatic transmission of cargo between conveyor lines.

[0003] The dual-drive component and four-guide rod structure jacking and transferring equipment used in the prior art often has a slight tolerance that causes the two drive components and the four guide rods to be non-parallel, which can lead to jamming. The equipment itself is blocked and cannot be used normally. In addition, the drive components are lifted vertically and have a relatively small load-bearing capacity. If the workpiece being transported is seriously overloaded, the compressed air will be compressed and the single-side drive component will retract slightly, causing the guide rod to be jammed, resulting in severe wear and abnormal equipment operation.

[0004] Therefore, the present application has developed a pallet lifting and transferring device to solve the problems existing in the prior art. Utility Model Content

[0033] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0034] like Figure 1-Figure 3As shown, a pallet lifting and transferring device comprises a fixed support seat 1, an upper lifting mechanism 2, a lifting mechanism 3, a guide rod 4, and a connecting rod 5; the lifting mechanism 3 is arranged between the fixed support seat 1 and the upper lifting mechanism 2, and the lifting mechanism 3 comprises a driving member 31, a sliding assembly 32, and a guiding assembly 33. When the driving member 31 is in an initial position, it is arranged parallel to the fixed support seat 1, and the sliding assembly 32 is provided with a guiding assembly 33 parallel to the sliding assembly 32. The sliding assembly 32 comprises a roller shaft 321 and a rolling member 33 assembled on the roller shaft 321. The same side ends of multiple connecting rods 5 are connected by the roller shaft 321, and the output end of the driving member 31 is connected to any roller shaft 32. 1 is fixedly connected, the fixed end of the driving member 31 is hinged with the fixed support seat 1, the driving member 31 moves to push the sliding assembly 32 so that the sliding assembly 32 slides on the guide plate 34 and the guide support rail 35, and lifts the upper lifting mechanism 2. The sliding assembly 32 slides on the guide plate 34, and supports the upper lifting mechanism 2 at multiple positions, so that the upper lifting mechanism 2 can be lifted smoothly, and because the sliding assembly 32 moves as a whole, it will not cause one side to deviate, resulting in imbalance. At the same time, because there is only one driving member 31, and it is not vertically set to perform the lifting action, but is lifted by the movement of the sliding assembly 32, thereby avoiding the jamming caused by the imbalance of air pressure.

[0035] In this embodiment, the lifting upper mechanism 2 includes a lifting plate 21 and a transport component 22. The transport component 22 is fixed on the lifting plate 21 and respectively arranged at both ends of the lifting plate 21. The driving mechanism 23 is directly connected to the transport component 22 through a driving shaft or through but not limited to belts, chains, etc. Preferably, a chain is used to connect the driving mechanism 23 and the transport component 22. When the lifting upper mechanism 2 is lifted, the chain can move in any direction without affecting the lifting of the lifting upper mechanism 2, and the driving mechanism 23 will not rise with the lifting mechanism, thereby reducing the load on the lifting upper mechanism 2. At the same time, there is no need to consider the weight and inertia of the load of the lifting upper mechanism 2, thereby improving the accuracy and stability of the lifting. Because the driving mechanism 23 is not directly connected to the transport component 22, the risk of equipment shutdown due to failure of mechanical connectors or transmission systems is reduced.

[0036] In one embodiment, if Figure 2-Figure 3As shown, the guide assembly 33 includes a guide plate 34 and a guide support rail 35, a plurality of guide support rails 35 are fixed on the lifting plate 21, and the plurality of guide support rails 35 are slidably connected with the corresponding plurality of guide plates 34 through rolling members 332; the guide plate 34 is fixed on the fixed support seat 1, and the plurality of guide plates 34 are respectively slidably arranged at the connection positions of the plurality of roller shafts 321 and the corresponding plurality of connecting rods 5 through rolling members 332. Specifically, the two guide support rails 35 are symmetrically arranged on both sides of the driving member 31, and the guide plates 34 are correspondingly arranged below the guide support rails 35, and the guide plates 34 are parallel to the guide support rails 35, so that the connecting rod 5 passes through the rolling members 332. When the lifting plate 21 moves, it can move in the same direction at the same time. The guide plate 34, the rolling element 332 and the guide support rail 35 support the lifting plate 21 in the same direction. By supporting the lifting plate 21 at different positions, the bearing capacity of the lifting upper mechanism 2 is improved, so that the lifting upper mechanism 2 can move smoothly. Among them, the length of the connecting rod 5 is equal to the distance between the same side surfaces of the two guide plates 34 in the extension direction of the connecting rod 5, so that the two rollers 321 can move to the bottom of the corresponding inclined surface 343 at the same time, instead of making the two ends of the lifting plate 21 different in height when the inclined surface 343 moves, affecting the stability of the equipment or even damaging the equipment.

[0037] Furthermore, if Figure 2-Figure 4 As shown, the guide plate 34 includes a first surface 341, a second surface 342 and an inclined surface 343 connecting the first surface 341 and the second surface 342. The first surface 341 is closer to the surface of the fixed support seat 1 as the initial position of the roller 321, and the second surface 342 is farther from the fixed support seat as the terminal position of the roller 321. The roller 321 slides from the first surface 341 through the inclined surface 343 to the second surface 342 so that the lifting upper mechanism 2 is lifted. Specifically, the first surface 341 and the second surface 342 are parallel to the surface of the fixed support seat 1, so that the roller 321 can stay stably on the first surface 341 and the second surface 342; the multiple inclined surfaces 343 are all inclined in one direction and have the same inclination angle, so that the roller 321 is more stable when passing through the inclined surface 343, and will not tilt or be unstable during movement due to the different heights or inclination angles of a certain inclined surface 343.

[0038] In another embodiment, a plurality of guide support rails 35 are fixed on the fixed support seat 1, and are slidably connected to the corresponding plurality of guide plates 34 through rolling members 332; the plurality of guide plates 34 are fixed on the lifting plate 21; the roller shaft 321 slides on the corresponding guide plates 34 and the guide support rails 35, and moves from the first surface 341 to the second surface 342 to lift the upper lifting mechanism 2.

[0039] As a further explanation, a plurality of guide support rails 35 and corresponding plurality of guide plates 34 can be arranged between the lifting upper mechanism 2 and the fixed support seat 1, and roller shafts 321 are correspondingly arranged between the plurality of guide support rails 35 and the plurality of guide plates 34 via rolling members 332. The driving member 31 is connected to any roller shaft 321, and pushes the sliding assembly 32 to move by pushing the roller shaft 321. The driving member 31 does not need to be arranged only between the plurality of connecting rods 5, nor does it need to be arranged with only two guide support rails 35 and two connecting rods 5 and two roller shafts 321. It is only necessary that the extension directions of the corresponding guide support rails 35, guide plates 34 and connecting rods 5 remain consistent. When the driving member 31 pushes the roller shaft 321, the roller shaft 321 approaches the corresponding inclined surface 343, so that the sliding assembly 32 moves from the first surface 341 to the second surface 342, thereby lifting the lifting upper mechanism 2.

[0040] Furthermore, if Figure 2 As shown, the guide rod 4 includes a sleeve 41 and a guide shaft 42. The lifting height of the guide shaft 42 is greater than the vertical distance between the first surface 341 and the second surface 342, so as to prevent the guide shaft 42 from moving to the end when the sliding component 32 moves on the inclined surface 343, resulting in the sliding component 32 not moving to the second surface 342, so that the lifting upper mechanism 2 cannot remain stable, affecting the stability of the equipment; the two guide rods 4 are respectively located at the diagonal positions of the jacking plate 21, which can balance and disperse the weight of the load during the jacking process, reduce the inclination and shaking of the lifting upper mechanism 2, thereby improving the stability and safety of the equipment, and also enable the lifting upper mechanism 2 to remain horizontal and vertical during the movement, avoiding deflection or loss of control, thereby improving the accuracy and reliability of the jacking process; compared with the arrangement of four guide rods 4, the arrangement of two guide rods 4 is simpler, reduces the number and complexity of components, thereby reducing manufacturing costs and maintenance difficulties.

[0041] The implementation principle of the embodiment of this application:

[0042] During the transportation process, the material moves to the top of the chain assembly 24. After the driving member 31 is started, it pushes the roller 321 to move and drives the sliding assembly 32 to slide. After the driving member 31 is started, the roller 321 slides between the guide plate 34 and the guide support rail 35 through the rolling member 332. The roller 321 starts to slide from the first surface 341, slides to the second surface 342 through the inclined surface 343 and stops. Because the height of the second surface 342 is higher than the height of the first surface 341, the lifting upper mechanism 2 is gradually lifted, and the roller 321 supports the lifting upper mechanism 2 at different positions through the rolling member 332, thereby improving the supporting force and stability during operation. After lifting, the driving mechanism 23 rotates to rotate a pair of transport components 22, thereby moving the material on the transport components 22.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
