Description

Technical Field

[0001] The utility model relates to the technical field of bagged fertilizer palletizing and depalletizing devices, and particularly relates to a rapid bagged fertilizer depalletizing device. Background Art

[0002] In the process of fertilizer production, the depalletizing of bagged fertilizers is a link with high labor intensity and low efficiency. The traditional manual depalletizing method is not only inefficient but also prone to causing occupational diseases of workers, such as pneumoconiosis. With the development of automation technology, various depalletizing devices have emerged on the market.

[0003] Currently, most of the existing bagged fertilizer depalletizing devices rely on single suction cups or simple grippers to perform depalletizing operations. The limitation of this method is that its single-operation ability is limited, and it is easy to drop or damage the bags. Some depalletizing tasks usually require workers to repeatedly perform operations such as grasping, transporting, and placing, resulting in low efficiency. At the same time, the dust generated during the depalletizing process can harm the health of workers, and improper handling may cause an explosion. Moreover, the size of fertilizer bags may vary due to factors such as production batches and packaging materials, and traditional depalletizing methods often have difficulty adapting to such changes.

[0004] Based on this, the utility model designs a rapid bagged fertilizer depalletizing device to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a rapid bagged fertilizer depalletizing device.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A rapid bagged fertilizer depalletizing device, including a fixed frame, a suction cup vacuum monitoring instrument, a connecting flange, a mounting frame, a suction cup mechanism, a slide rail, and a sliding mechanism. The suction cup vacuum monitoring instrument and the connecting flange are fixedly arranged at the center of the upper end of the fixed frame. Slide rails are symmetrically and fixedly connected to the left and right sides of the two crossbeams of the fixed frame. A sliding mechanism is movably connected to the slide rails. The lower ends of the sliding mechanisms are fixedly installed with suction cup mechanisms. The mounting frame is fixedly connected to the center of the lower end of the fixed frame, and a suction cup mechanism is also fixedly installed at the lower end of the mounting frame.

[0007] As a preferred technical solution of the utility model, the sliding mechanism includes a mounting platform, sliders, and positioning pins. Sliders are fixedly connected to the four corners of the upper end of the mounting platform. The sliders are respectively slidably connected to the corresponding slide rails. Positioning pins are arranged on all four sliders, and the sliders are fixed to the slide rails through the positioning pins.

[0008] As a preferred technical solution of the present utility model, the sucker mechanism includes a fixing plate, a connection component, a control device, a sucker fixture and an air pump. The fixing plate is fixedly connected to the upper end of the control device. Connection components are fixedly connected to the four corners of the upper end of the fixing plate, and the tops of the four connection components are fixedly connected to the installation platform of the sliding mechanism.

[0009] As a preferred technical solution of the present utility model, the sucker fixture is fixedly connected to the lower end of the control device, and an air pump is fixedly installed on the front surface of the control device.

[0010] As a preferred technical solution of the present utility model, the sucker fixture includes a housing body, a surrounding air intake channel, a barb device and a buffer mechanism. A surrounding air intake channel is arranged at the inner top of the housing body, and a barb device is arranged on the inner ring of the housing body.

[0011] As a preferred technical solution of the present utility model, an annular groove is opened at the lower end of the housing body, and a buffer mechanism is arranged inside the annular groove.

[0012] As a preferred technical solution of the present utility model, a vacuum channel is opened inside the control device, and the vacuum channel is communicated with the inner cavity of the sucker fixture.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By optimizing the existing fixed sucker fixture, the present utility model designs three sucker mechanisms. Each sucker mechanism is independently controlled and the distance between them can be adjusted, enabling the simultaneous adsorption and grasping of three packages of bagged fertilizers. Through the adsorption and grasping, the breaking of packages during palletizing can be avoided. And through the vacuum degree inspection instrument installed on the fixed frame, not only can the vacuum degree be monitored in real time to ensure the stability of adsorption, but also fault warning and maintenance can be carried out to avoid adverse consequences caused by faults. This device adopts a highly integrated automatic design, without manual intervention, greatly improving the palletizing efficiency of bagged fertilizers and avoiding the harm of dust to workers' health during palletizing;

[0015] 2. Through the structural design of the built-in barbs and surrounding air intake of the sucker fixture, the barb device designed on the inner ring of the material contact end of the sucker fixture can maintain the pressure of the vacuum cavity. And by adopting the sucker fixture with a surrounding air intake design, air or gas can be introduced more evenly during the adsorption process, improving the adsorption effect and stability, further enhancing the adsorption capacity of the sucker fixture, thereby preventing the fertilizer bags from falling, being applicable to the palletizing of fertilizer bags of different sizes, having good practicability, and reducing the cost investment of the equipment.

Positioning pins 703 are provided on all four sliders 702, and the sliders 702 are fixed to the slide rails 6 through the positioning pins 703.

[0026] Through the two movable suction cup mechanisms 5 and one fixed suction cup mechanism 5 provided on the fixed frame 1, the simultaneous grasping of three-pack bagged fertilizers can be achieved. And through the connection structure formed by the fixed frame 1, the slide rails 6, the sliding mechanism 7, and the suction cup mechanism 5, the distance between the two suction cup mechanisms 5 can be adjusted according to the usage situation to meet the requirements of palletizing and depalletizing. And through the suction cup vacuum monitoring instrument 2 provided on the fixed frame 1, the vacuum degree can be monitored in real time to ensure the stability of adsorption, which is convenient for fault warning.

[0027] Please refer to Figure 2 、 Figure 3 and Figure 4 The suction cup mechanism 5 includes a fixed plate 501, a connection component 502, a control device 503, a suction cup fixture 504, and an air pump 505. The fixed plate 501 is fixedly connected to the upper end of the control device 503. At the four corners of the upper end of the fixed plate 501, connection components 502 are fixedly connected. The tops of the four connection components 502 are fixedly connected to the installation platform 701 of the sliding mechanism 7.

[0028] The suction cup fixture 504 is fixedly connected to the lower end of the control device 503, and an air pump 505 is fixedly installed on the front surface of the control device 503.

[0029] The suction cup fixture 504 includes an outer shell 5041, a peripheral air intake channel 5042, a barb device 5043, and a buffer mechanism 5044. A peripheral air intake channel 5042 is provided at the inner top of the outer shell 5041, and a barb device 5043 is provided on the inner ring of the outer shell 5041.

Then it is moved to the position below the fertilizer bags to be grabbed and lowered. After the suction cup fixture 504 contacts the fertilizer bags, it continues to lower until the suction cup vacuum monitoring instrument 2 detects that the vacuum degree inside the suction cup fixture 504 reaches the preset value and then stops lowering. Then the vacuum partition control system starts to distribute the solenoid valves, enabling the suction cup mechanisms 5 that need to work to have the condition of receiving vacuum supply, thus achieving the grasping of the fertilizer bags. Then the fertilizer bags are moved to the placement area, and the suction cup mechanisms 5 place the fertilizer bags on the material rack. The solenoid valve for breaking the vacuum is activated, blowing positive pressure air into the suction cup fixture 504 to achieve the purpose of breaking the vacuum, enabling the fertilizer bags to smoothly separate from the suction cup fixture 504 and realizing the rapid depalletizing of the fertilizer bags.
