[0003] With the continuous development of science and technology in our country, the scale of industrial production is getting larger and larger, and it is gradually improved towards automation. Therefore, in the process of modern industrial production, it is often necessary to connect multiple production and processing procedures together to form a complete process flow. After the previous process is completed, there is a process of transporting the workpiece to the processing equipment of the next process. Especially in the process of lifting the workpiece, manual operation is often required to ensure accurate transportation. In the current tooling box processing industry, the material lifting and tooling box unstacking processes are all completed by manual operation. Manually lifting the tooling box or other materials from a low place to a high place and separating the tooling boxes one by one not only has a high labor intensity and low efficiency, but also requires multiple people and multiple shifts for long-term production operations, resulting in high labor costs.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments: As Figures 1 to 6 shown:

[0031] An automatic lifting and progressive transportation device includes a jacking mechanism 1, a lifting mechanism 2, a bilateral transportation belt mechanism 3 and a progressive mechanism 4. The jacking mechanism 1, the lifting mechanism 2 and the bilateral transportation belt mechanism 3 are arranged inside the automatic lifting and progressive transportation device.

[0032] The bilateral transportation belt mechanism 3 includes a belt line 31, belt pulleys 32, axle shafts 33, a reduction motor 34 and a mounting frame 35. The bilateral transportation belt mechanism 3 is provided with two axle shafts 33. Belt pulleys 32 are installed at both ends of the axle shafts 33. The belt line 31 is installed on the belt pulleys 32. The two axle shafts 33 are connected by the belt pulleys 32 and the belt line 31 on both sides. A wheel axle gear 36 is arranged on one side of the axle shaft 33.

[0033] The reduction motor 34 is fixedly connected to the mounting frame 35. The reduction motor 34 is arranged below the axle shaft 33. A motor gear 38 is arranged on the motor shaft of the reduction motor 34. The motor gear 38 is meshed with the wheel axle gear 36 through a chain.

[0034] The mounting frame 35 is arranged at the bottom of the bilateral transportation belt mechanism 3. The mounting frame 35 is welded by square tubes. The mounting frame 35 is fixedly installed on the lifting mechanism 2. The mounting frame 35 rises or falls following the lifting mechanism 2.

[0035] The rotation of the reduction motor 34 drives the motor gear 38 on the motor shaft to rotate. The motor gear 38 drives the meshed wheel axle gear 36 to rotate through the chain, thereby driving the axle shafts 33, the belt pulleys 32 and the belt line 31 to operate, realizing the transportation of the tooling box stack on the belt line 31 and transporting the tooling box stack into the lifting mechanism 2.

[0036] The lifting mechanism 1 includes a lifting plate 11, a lifting cylinder 12, a linear slide rail 13, and a lifting mounting plate 14. The lifting mechanism 1 is installed between the two axles 33 of the bilateral conveyor belt mechanism 3, and the lifting mounting plate 14 is fixedly connected to the mounting frame 35 of the bilateral conveyor belt mechanism 3.

[0037] There are two sets of lifting cylinders 12, two sets of linear slide rails 13, two sets of sliders 15, and two sets of lifting plates 11 provided on the lifting mounting plate 14.

[0038] The lifting cylinder 12 and the linear slide rail 13 are installed on the lifting mounting plate 14. There is a slider 15 on the linear slide rail 13, and the slider 15 is connected to the telescopic part of the lifting cylinder 12.

[0039] The lifting plate 11 is connected to the slider 15. The lifting plate 11 is of a triangular structure, and the top of the lifting plate 11 is of a planar structure. The lifting plate 11 is used to lift the tooling box.

[0040] When the lifting cylinder 12 expands and contracts, it drives the lifting plate 11 to slide up and down along the linear slide rail 13, realizing the lifting of the tooling box on the bilateral conveyor belt mechanism 3. The lifting mechanism 1 is arranged in the middle of the bilateral conveyor belt mechanism 3 to ensure the stability of the lifted tooling box.

[0041] The progressive mechanism 4 includes a module 41, a box loading frame 42, a box pushing cylinder 43, and a cylinder fixing frame 44. The module 41 is fixedly installed on the cylinder fixing frame 44. The module 41 is connected to the box loading frame 42, and the cylinder fixing frame 44 is fixedly connected to the high-level conveyor belt line.

[0042] The box loading frame 42 is of a cubic structure. There are side plates on the left and right sides of the box loading frame 42, and one side of the box loading frame 42 is fixedly connected to the moving part of the module 41.

[0043] Two fixing blocks 421 are respectively provided on both sides of the bottom of the box loading frame 42. A rotating shaft 422 is installed between the fixing blocks 421 on the same side, and a wedge-shaped rotating block 423 is provided on the rotating shaft 422.

[0044] The cross-section of the wedge-shaped rotating block 423 is of a triangular structure, and the connection of the straight sides of the triangular structure is rounded.

[0045] The wedge-shaped rotating block 423 can rotate upward by 90 degrees around the rotating shaft 422. When the lifting mechanism 1 lifts the stack of tooling boxes into the interior of the box loading frame 42, it pushes the wedge-shaped rotating block 423 to rotate upward. When the stack of tooling boxes is higher than the wedge-shaped rotating block 423, the wedge-shaped rotating block 423 automatically rotates downward under the action of gravity to restore the horizontal state. The lifting mechanism 1 descends, and the stack of tooling boxes stops above the wedge-shaped rotating block 423.

[0046] The pushing box cylinder 43 is connected to the cylinder fixing frame 44, and the telescopic part of the pushing box cylinder 43 faces the box loading frame 42.

[0047] The automatic lifting and progressive transportation device is controlled by a PLC programmable controller. A number of sensors are provided inside the automatic lifting and progressive transportation device, and the sensors are connected to the PLC programmable controller.

[0048] The sensors are used to sense whether the tooling box stack reaches the entrance position of the lifting mechanism 2 and whether the tooling box stack completely enters the inside of the lifting mechanism 2.

[0049] When the tooling box stack reaches the entrance of the lifting mechanism 2, the sensors sense the tooling box stack, transmit the signal to the PLC programmable controller, and the PLC controls the deceleration motor 34 of the bilateral transportation belt mechanism 3 to actuate, driving the belt line 31 to operate, and sending the tooling box stack on the belt 31 into the lifting mechanism 2.

[0050] When the sensors sense that the work box stack completely enters the inside of the lifting mechanism 2, the sensors transmit the signal to the PLC programmable controller, and the PLC controls the lifting mechanism 2 to start rising, lifting the height of the bilateral transportation belt mechanism 3 and the tooling box stack.

[0051] The working principle of the present invention: The tooling box stack is transported to the entrance of the lifting mechanism 2. The sensors sense the position of the tooling box stack and transmit the signal to the PLC control system. The PLC control system controls the deceleration motor 34 of the bilateral transportation belt mechanism 3 to start. The deceleration motor 34 rotates to drive the motor gear 38 on the motor shaft to rotate, thereby driving the wheel shaft 33, the belt pulley 32 and the belt line 31 to operate, and transporting the tooling box stack into the inside of the lifting mechanism 2. After the sensors sense that the tooling box stack completely enters the inside of the lifting mechanism 2, they transmit the signal to the PLC control system. The PLC control system controls the lifting mechanism 2 to start rising, lifting the bilateral transportation belt mechanism 3 together with the tooling box stack to a high place. When the tooling box stack is lifted to the bottom of the box loading frame 42, the PLC control system controls the jacking cylinder 12 of the jacking mechanism 1 to actuate, jacking up the tooling box stack and jacking the tooling box stack into the inside of the box loading frame 42, while pushing the wedge-shaped rotating block 423 to rotate upward. When the tooling box stack is higher than the wedge-shaped rotating block 423, the tooling box stack completely enters the inside of the box loading frame 42. The wedge-shaped rotating block 423 automatically rotates downward under the action of gravity and returns to the horizontal state. The jacking mechanism 1 descends, and the tooling box stack stops above the wedge-shaped rotating block 423. The module 41 controls the box loading frame 42 to drive the tooling box stack to rise in sequence. When the uppermost work box rises to the highest point, the pushing box cylinder 43 acts to push the uppermost work box onto the high belt line. Then, the module 41 drives the box loading frame 42 and the tooling box stack to rise one grid again, and the pushing box cylinder 43 acts again to push the uppermost work box onto the belt line, and so on, until all the work boxes are pushed and completed.

[0052] Main functions of the present invention: The device uses a bilateral conveyor belt mechanism to horizontally transport the tooling box stack, uses a lifting mechanism to stably lift the bilateral conveyor belt mechanism and the tooling box stack to a high place, uses a jacking mechanism to realize the separation and lifting of the tooling box stack from the bilateral conveyor belt, uses the modules of the progressive mechanism to drive the box loading frames to rise in sequence, realizes the sequential elevation of the tooling box stacks in the box loading frames, and finally uses a box pushing cylinder to sequentially deliver the tooling boxes. Through the mutual cooperation among the bilateral conveyor belt mechanism, the lifting mechanism, the jacking mechanism and the progressive mechanism, and using a PLC control system to control each mechanism, the automatic and stable lifting, progressive transportation and sequential unstacking processes of the tooling boxes are realized. It replaces manual handling operations, effectively reduces the labor intensity, reduces the labor cost, and improves the production efficiency.

[0053] In summary, after reading the present invention document, various other corresponding transformation schemes made by those of ordinary skill in the art without creative mental labor according to the technical solutions and technical concepts of the present invention all fall within the scope protected by the present invention.
