Description

Technical Field

[0001] The utility model is applied to the technical field of physical error prevention in transportation, and particularly relates to a physical unlocking error prevention hoist. Background Art

[0002] In the process of automated production, products need to be transferred via pallets. Transferring via pallets can facilitate the production, assembly and testing of products. During the transfer process, inaccurate positioning may occur, causing the pallet to enter the lifting position in advance and fall off. At present, the loading and unloading of pallets is mainly controlled manually. After one pallet is loaded, the next pallet is loaded. This method has high labor costs and cannot guarantee the spacing between pallets. It is easy for the pallet spacing to be small, resulting in the lifting mechanism not being lifted into place during the transfer process. The pallet enters the top lifting position and causes the pallet to fall. In addition, some products are heavy, and it is impossible to manually move the pallet to the conveyor line at one time. External lifting tools are required for loading, which is inefficient, or blocked by traditional cylinders. However, the existing technology can only ensure the effectiveness and safety of the hoist transporting pallets when there are no bugs in the PLC program and the pneumatic stop components and electronic components are not damaged. If a physical unlocking and error-proofing hoist with a simple structure, mechanical structure to limit the pallet, physical unlocking and error-proofing, and higher safety can be designed, the above problems can be solved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a physical unlocking and error-proof hoist with a simple structure, which limits the pallet through a mechanical structure, physically unlocks and prevents errors, and has higher safety.

[0004] The technical solution adopted by the utility model is: the utility model includes a lifting component and a first conveying component, the lifting component includes a frame and a lifting module, the lifting module includes a supporting base and a second conveying component, the second conveying component is arranged on the supporting base, the frame is provided with a plurality of slide rail modules, the connecting side of the supporting base is connected with a plurality of movable ends of the slide rail modules, the first conveying component is arranged in connection with the frame and cooperates with the second conveying component, both ends of the first conveying component are provided with blocking and error-proofing mechanisms, the blocking end of the blocking and error-proofing mechanism cooperates with the tray on the first conveying component, and an unlocking block is provided on the corresponding side of the supporting base, and the unlocking block cooperates with the lifting end of the blocking and error-proofing mechanism.

[0005] Furthermore, a lifting motor is provided at the upper end of the frame, and a transmission belt assembly is provided at one side of the frame. The movable end of the lifting motor cooperates with the transmission belt assembly, and the support base is clamped with the belt end of the transmission belt assembly. The lifting motor drives the transmission belt assembly to move by forward or reverse rotation to make the support base rise or fall.

[0006] Furthermore, the blocking and error-proofing mechanism includes a mounting seat and a blocking rod, a rotating shaft is provided in the middle of the blocking rod, the rotating shaft divides the blocking rod into a blocking rod lifting part and a blocking rod blocking part, and the blocking rod is rotatably matched with the mounting seat via the rotating shaft.

[0007] Furthermore, the mounting seat is provided with a limiting column, the upper end surface of the blocking portion of the blocking rod is limitedly matched with the limiting column, and the blocking portion of the blocking rod is matched with an edge of one side of the tray.

[0008] Furthermore, a lifting extension rod is provided at the end of the lifting portion of the barrier rod, and the unlocking block cooperates with the lower end surface of the lifting extension rod.

[0009] Furthermore, a limiting ring is provided between the blocking rod and the rotating shaft.

[0010] Furthermore, the frame is provided with a protective baffle.

[0011] Furthermore, both ends of the first conveying component can cooperate with the lifting component.

[0012] The beneficial effect of the utility model is as follows: the utility model uses a simple mechanical structure to rotate the baffle rod through the rotating shaft to fit on the inner side of the feeding end of the first conveying component, and the rotating shaft divides the baffle rod into two parts of different lengths. Under the action of gravity, the lifting part of the baffle rod is longer and will perform free fall motion, causing the baffle rod to rotate as a whole, and the blocking part of the baffle rod will block the pallet, preventing the pallet from entering the lifting position. When the lifting module is lifted into place, the unlocking block will lift the lifting part of the baffle rod, allowing the pallet to pass smoothly. The structure is simple and the performance is stable. The mechanical structure will not be affected by the bug of the PLC program, thereby ensuring smooth pallet transfer and lifting.

[0019] like Figures 1 to 6 As shown, in this embodiment, the utility model includes a lifting component 1 and a first conveying component 2, the lifting component 1 includes a frame 3 and a lifting module 4, the lifting module 4 includes a supporting base 41 and a second conveying component 42, the second conveying component 42 is arranged on the supporting base 41, the frame 3 is provided with a plurality of slide rail modules 5, the connecting side of the supporting base 41 is connected to the movable ends of the plurality of slide rail modules 5, the first conveying component 2 is arranged in connection with the frame 3 and cooperates with the second conveying component 42, both ends of the first conveying component 2 are provided with blocking and error-proofing mechanisms 6, the blocking end of the blocking and error-proofing mechanism 6 cooperates with the tray 7 on the first conveying component 2, and the corresponding side of the supporting base 41 is provided with an unlocking block 8, the unlocking block 8 cooperates with the lifting end of the blocking and error-proofing mechanism 6. It can be seen that the pallet 7 is conveyed to the lifting component 1 through the first conveying component 2, and the blocking and error-proofing mechanism 6 at the loading end is in a blocking state when the lifting module 4 is not lifted into place. The pallet 7 cannot enter the lifting module 4 through the first conveying component 2, thereby achieving an error-proofing effect. When the lifting module 4 is lifted into place, the unlocking block 8 unlocks the blocking and error-proofing mechanism 6, so that the pallet 7 can pass smoothly.

[0020] like Figure 1 As shown, in this embodiment, a lifting motor 9 is provided at the upper end of the frame 3, and a transmission belt assembly 10 is provided at one side of the frame 3. The movable end of the lifting motor 9 cooperates with the transmission belt assembly 10, and the support base 41 is clamped with the belt end of the transmission belt assembly 10. The lifting motor 9 drives the transmission belt assembly 10 to move by forward or reverse rotation to make the support base 41 rise or fall. It can be seen that the lifting motor 9 rotates to drive the transmission belt assembly 10 to move, and the support base 41 is connected to the transmission belt assembly 10 to lift or fall the second transmission assembly 42.

[0021] like Figures 4 to 6As shown, in this embodiment, the blocking and error-proofing mechanism 6 includes a mounting seat 61 and a blocking rod 62. A rotating shaft 63 is provided in the middle of the blocking rod 62. The rotating shaft 63 divides the blocking rod 62 into a blocking rod lifting portion 64 and a blocking rod blocking portion 65. The blocking rod 62 is rotatably matched with the mounting seat 61 through the rotating shaft 63. It can be seen that the blocking rod lifting portion 64 and the blocking rod blocking portion 65 are different in length. The blocking rod lifting portion 64 is longer. In the initial state, the blocking lifting portion 64 is rotated and descended to a low position under the action of gravity, and the blocking rod blocking portion 65 is in a high position to achieve a blocking effect. When the unlocking block 8 is lifted into place, the blocking rod lifting portion 64 and the blocking rod blocking portion 65 are in a parallel state, so that the tray 7 can pass smoothly.

[0022] like Figures 4 to 6 As shown, in this embodiment, the mounting seat 61 is provided with a limiting column 66, the upper end surface of the blocking rod blocking portion 65 is limitedly matched with the limiting column 66, and the blocking rod blocking portion 65 is matched with a side edge of the tray 7. It can be seen that the limiting column 66 can make the blocking rod blocking portion 65 at a blocking angle in the initial state to block the tray 7 from passing.

[0023] like Figures 4 to 6 As shown, in this embodiment, a lifting extension rod 67 is provided at the end of the barrier rod lifting portion 64, and the unlocking block 8 cooperates with the lower end surface of the lifting extension rod 67. It can be seen that the lifting extension rod 67 of different sizes and specifications can be provided according to different usage scenarios. Since the barrier rod lifting portion 64 is in an oblique downward state in the initial state, the lifting extension rod 67 with a deflection angle to the barrier rod lifting portion 64 can make the unlocking block 8 lift more smoothly without scratches and scratches.

[0024] like Figure 4 As shown, in this embodiment, a limiting ring 68 is further provided between the blocking rod 62 and the rotating shaft 63. It can be seen that the limiting ring 68 can ensure that the blocking rod 62 does not deviate during the rotation process, making the lifting process more stable.

[0025] like Figure 1 As shown, in this embodiment, the frame 3 is provided with a protective baffle 11. It can be seen that the protective baffle 11 provides a protective function during the lifting process.

[0026] like Figure 1 As shown, in this embodiment, both ends of the first conveying component 2 can be matched with the lifting component 1. It can be seen that both ends of the first conveying component 2 can be provided with the lifting component 1, which can meet the requirements of loading and unloading at the same time.

[0027] The working principle of the utility model is as follows: before starting the equipment, the pallet 7 is placed into the feed end of the first conveying component 2, the pallet 7 enters the blocking position, the blocking rod 62 is tilted at a certain angle under the action of gravity, so that the blocking rod blocking part 65 blocks the pallet 7, and when the second conveying component 42 is lifted into place, the unlocking block 8 contacts and lifts the lifting extension rod 67, so that the blocking rod lifting part 64 rotates around the rotating shaft 63, the blocking rod lifting part 64 and the blocking rod blocking part 65 are in a parallel state, the pallet 7 enters the second conveying component 42 through the first conveying component 2 and descends to complete the unloading, and the above steps can be repeated to realize the physical unlocking and error-proof lifting of the pallet for automatic transfer.
