Description

Technical Field

[0001] This utility model relates to the field of ton bag unloading technology, specifically providing a ton bag suction device. Background Technology

[0002] BOOM (Bulk Interchange Bag), also known as a flexible container or FIBC, is a type of flexible packaging container commonly used for packaging and transporting bulk materials such as powders and granules. In the production processes of many industries, including chemical, food, pharmaceutical, and plastics, it is frequently necessary to transfer materials stored in BOOMs to subsequent processing equipment or storage facilities.

[0003] Traditional ton bag unloading methods are mostly manual, such as opening the bottom discharge port of the ton bag or directly lifting and tilting the bag to transfer materials. This method is not only labor-intensive and inefficient, but also easily causes dust to fly when handling materials with high dust content, polluting the working environment, endangering the health of operators, and resulting in material waste. To overcome the problems of manual unloading, the industry has gradually adopted ton bag suction equipment. Existing ton bag suction equipment usually uses negative pressure airflow to suck the material out of the ton bag. However, existing ton bag suction equipment still has significant shortcomings in terms of automation; for example, it cannot detect whether the ton bag has been properly lifted or properly positioned.

If a dependency and / or order is required, it will be explicitly stated in the context, or it will be obvious to those skilled in the art when understanding the specific embodiments.

[0021] Traditional ton bag unloading methods are mostly manual, such as opening the bottom discharge port of the ton bag or directly lifting and tilting the bag to transfer materials. This method is not only labor-intensive and inefficient, but also easily causes dust to fly when handling materials with high dust content, polluting the working environment, endangering the health of operators, and resulting in material waste. To overcome the problems of manual unloading, the industry has gradually adopted ton bag suction equipment. Existing ton bag suction equipment usually uses negative pressure airflow to suck the material out of the ton bag. However, existing ton bag suction equipment still has significant shortcomings in terms of automation; for example, it cannot detect whether the ton bag has been properly lifted or properly positioned.

[0022] To address the significant shortcomings in automation levels of existing ton bag suction equipment, this utility model provides a ton bag suction device, such as... Figure 1 As shown, the ton bag suction equipment includes a frame assembly 1, a suction assembly 2, and multiple lifting assemblies 3, etc.

[0023] like Figure 2As shown, the frame assembly 1 includes a frame body 11 and a suction frame 12. An inner space 111 is formed on the inner side of the frame body 11, and the suction frame 12 is disposed on the upper side of the frame body 11. Each of the lifting components 3 includes a suction mechanism 21 and a moving mechanism 22. The suction mechanism 21 is used to suck out the material from the ton bag 5. The moving mechanism 22 is disposed on the suction frame 12 and connected to the suction mechanism 21. The moving mechanism 22 is used to drive the suction end of the suction mechanism 21 to move into or out of the ton bag 5. Multiple lifting components 3 are respectively disposed on the frame body 11 and located on both sides of the frame body 11 in the width direction. Each lifting component 3 includes a lifting mechanism 31 and a connecting mechanism 32. The connecting mechanism 32 is disposed on the frame body 11 through the lifting mechanism 31 and is used to detachably connect to the ton bag 5. The lifting mechanism 31 is used to drive the ton bag 5 to move up and down along the height direction of the frame body 11 through the connecting mechanism 32. In actual use, the connecting mechanism 32 of each lifting component 3 is connected to the ton bag 5, and then the lifting mechanism 31 drives the ton bag 5 to rise or lower.

[0024] Continue to refer to Figure 2 The inner space 111 of the frame body 11 includes a first ton bag space portion 1111, a second ton bag space portion 1112, and a pallet space portion 1113. Both the first ton bag space portion 1111 and the second ton bag space portion 1112 are used to accommodate ton bags 5, and the pallet space portion 1113 is used to accommodate pallets 6. The second ton bag space portion 1112 is located directly above the first ton bag space portion 1111, and the pallet space portion 1113 is located directly below the first ton bag space portion 1111. It should be noted that when the inner space 111 accommodates two ton bags 5 stacked on a pallet 6, the pallet 6 is placed within the pallet space portion 1113, the first (lower) ton bag 5 on the pallet 6 is placed within the first ton bag space portion 1111, and the second (upper) ton bag 5 on the pallet 6 is placed within the second ton bag space portion 1112.

[0025] like Figures 2 to 4 As shown, the frame body 11 is equipped with a first ton bag detection device 41 and a second ton bag detection device 42. The first ton bag detection device 41 is used to detect whether there is a ton bag 5 in the lower area of ​​the first ton bag space 1111, and the second ton bag detection device 42 is used to detect whether there is a ton bag 5 in the lower area of ​​the second ton bag space 1112. Specifically, as... Figure 3As shown, both the first ton bag detection device 41 and the second ton bag detection device 42 are through-beam photoelectric sensors. The transmitter and receiver of the first ton bag detection device 41 are respectively mounted on the frame body 11 and located on both sides of its width direction. The transmitter and receiver of the second ton bag detection device 42 are respectively mounted on the frame body 11 and located on both sides of its width direction, and are located above the first ton bag detection device 41.

[0026] It should be noted that, as Figure 2 As shown, when the inner space 111 contains two ton bags 5 stacked on the pallet 6, if the ton bag 5 on the second layer is lifted normally to the preset height by each lifting component 3, the ton bag 5 will completely leave the detection area of ​​the second ton bag detection device 42, and the detection result of the second ton bag detection device 42 on the lower area of ​​the second ton bag space 1112 will be that there is no ton bag 5. If the ton bag 5 on the second layer does not rise normally to the preset height, for example, if a certain lifting component 3 fails to operate normally, the lower part of the ton bag 5 will still be within the detection area of ​​the second ton bag detection device 42, and thus can be detected by the second ton bag detection device 42. That is, the detection result in this case is that there is a ton bag 5, which needs to be adjusted and checked by the staff.

[0027] Similarly, if the inner space 111 contains a ton bag 5 placed on a tray 6: if the ton bag 5 is lifted normally to the preset height by each lifting component 3, the ton bag 5 will completely leave the detection area of ​​the first ton bag detection device 41, and the detection result of the first ton bag detection device 41 on the lower area of ​​the first ton bag space 1111 will be that the ton bag 5 does not exist; if the ton bag 5 does not rise normally to the preset height, the lower part of the ton bag 5 will still be within the detection area of ​​the first ton bag detection device 41, and thus can be detected by the first ton bag detection device 41. That is, the detection result in this case is that the ton bag 5 exists, and the staff needs to adjust and check it.

[0028] The ton bag suction device provided in this embodiment of the utility model can automatically detect whether there is a ton bag 5 in the lower area of ​​the ton bag space by setting a ton bag detection device, thereby monitoring in real time whether the ton bag 5 is pulled up or in place normally, effectively avoiding operation interruption or failure caused by abnormal lifting of the ton bag 5, and significantly improving the automation level and operational reliability of the equipment.

[0029] Continue to refer to Figures 2 to 4 In this embodiment of the invention, the frame body 11 is further provided with a pallet detection device 47. There are two pallet detection devices 47, which are used to detect whether a pallet 6 exists within the pallet space portion 1113. Specifically, as... Figure 3As shown, the pallet detection device 47 is a through-beam photoelectric sensor. The transmitter and receiver of the through-beam photoelectric sensor are respectively mounted on the frame body 11 and located on both sides of its width direction. It should be noted that if both pallet detection devices 47 can detect the pallet 6, it means that the pallet 6 is completely placed within the pallet space portion 1113, and the detection result is that the pallet 6 exists; if at least one of the two pallet detection devices 47 cannot detect the pallet 6, it means that the pallet 6 is not completely placed within the pallet space portion 1113, and the detection result is that the pallet 6 does not exist, requiring adjustment and inspection by personnel.

[0030] The ton bag suction device provided in this embodiment of the utility model can accurately determine whether the pallet 6 is fully in place by setting a pallet detection device 47, which replaces the inefficient and error-prone manual confirmation, thereby avoiding operation interruption or failure that may be caused by the pallet 6 being offset or not fully in place, and further improving the automation level and operational reliability of the equipment.

[0031] like Figure 3 and Figure 4 As shown, the frame body 11 of this embodiment of the invention has a first gantry section 112 and a second gantry section 113 respectively constructed on its front and rear sides. A first gantry gate 1121 is formed on the inner side of the first gantry section 112, and a second gantry gate 1131 is formed on the inner side of the second gantry section 113. Both the first gantry gate 1121 and the second gantry gate 1131 are used to allow the ton bag 5 to pass through so that it can enter the inner space 111. In actual use, the ton bag 5 can be selected to be fed into the inner space 111 from either the first gantry gate 1121 or the second gantry gate 1131, depending on the actual usage.

[0032] Further reference Figure 3 and Figure 4The first gantry section 112 is equipped with a first grating sensor 43 and a second grating sensor 44. The first grating sensor 43 is used to detect whether the ton bags 5 on the first layer of the pallet 6 pass through the first gantry gate 1121, and the second grating sensor 44 is used to detect whether the ton bags 5 on the second layer of the pallet 6 pass through the first gantry gate 1121. The second gantry section 113 is equipped with a third grating sensor 45 and a fourth grating sensor 46. The third grating sensor 45 is used to detect whether the ton bags 5 on the first layer of the pallet 6 pass through the second gantry gate 1131, and the fourth grating sensor 46 is used to detect whether the ton bags 5 on the second layer of the pallet 6 pass through the second gantry gate 1131. Specifically, the transmitters and receivers of the first grating sensor 43 and the second grating sensor 44 are respectively located on the first gantry section 112 and on both sides of the width direction of the frame body 11, and the transmitters and receivers of the third grating sensor 45 and the fourth grating sensor 46 are respectively located on the second gantry section 113 and on both sides of the width direction of the frame body 11.

[0033] It should be noted that if both the first grating sensor 43 and the second grating sensor 44 detect that a ton bag 5 has passed through, it is determined that two layers (two) of ton bags 5 have passed through the first gate 1121. If the first grating sensor 43 detects that a ton bag 5 has passed through but the second grating sensor 44 detects that no ton bag 5 has passed through, it is determined that a single layer (single) of ton bag 5 has passed through the first gate 1121. If both the first grating sensor 43 and the second grating sensor 44 detect that no ton bag 5 has passed through, it is determined that no ton bag 5 has passed through the first gate 1121. If the first grating sensor 43 detects that no ton bag 5 has passed through but the second grating sensor 44 detects that a ton bag 5 has passed through, it is determined that an abnormality has occurred and staff need to adjust and check it.

[0034] Similarly, if both the third grating sensor 45 and the fourth grating sensor 46 detect that a ton bag 5 has passed through, it is determined that two layers (two) of ton bags 5 have passed through the second gate 1131. If the third grating sensor 45 detects that a ton bag 5 has passed through and the fourth grating sensor 46 detects that no ton bag 5 has passed through, it is determined that a single layer (single) of ton bag 5 has passed through the second gate 1131. If both the third grating sensor 45 and the fourth grating sensor 46 detect that no ton bag 5 has passed through, it is determined that no ton bag 5 has passed through the second gate 1131. If the third grating sensor 45 detects that no ton bag 5 has passed through and the fourth grating sensor 46 detects that a ton bag 5 has passed through, it is determined that an abnormality has occurred and staff need to adjust and check it.

[0035] The ton bag feeding device provided in this embodiment of the utility model achieves precise monitoring of the passing status of the ton bags 5 by setting up grating sensors. In addition, the grating sensors are arranged in layers, enabling the device to accurately identify the number and layer height of the feeding ton bags 5. Furthermore, based on the detection signals of the grating sensors, the device can provide reliable initial operating conditions for subsequent ton bag 5 lifting, precise positioning, and feeding processes, thereby achieving smooth and precise automated connection between each process, further improving the automation level and operational reliability of the device.

[0036] like Figure 5 As shown, the movable mechanism 22 of this embodiment includes a first drive motor 221, a lead screw 222, a lead screw nut 223, a first guide rod 224, and a first slider 225. The first drive motor 221 is disposed on the upper side of the suction frame 12, and its rotation axis is arranged along the height direction of the frame body 11. The lead screw 222 is arranged along the height direction of the frame body 11. The upper end of the lead screw 222 is drivenly connected to the rotation axis of the first drive motor 221 through a coupling. The lower end of the lead screw 222 is rotatably disposed on the lower side of the suction frame 12. The lead screw nut 223 is threaded onto the lead screw 222 and connected to the sleeve 212 of the suction mechanism 21. The two ends of the first guide rod 224 are respectively fixedly disposed on the suction frame 12 and arranged parallel to the lead screw 222. The first slider 225 is sleeved on the first guide rod 224 and connected to the sleeve 212 of the suction mechanism 21. The first drive motor 221 drives the lead screw 222 to rotate, causing the lead screw nut 223 to move up and down along the height direction of the frame body 11. This, in turn, drives the suction mechanism 21 to move up and down through the first slider 225, thereby causing the suction end of the suction mechanism 21 to move into or out of the ton bag 5.

[0037] like Figure 5 and Figure 6 As shown, the suction mechanism 21 of this utility model embodiment includes a suction pipe 211 and a sleeve 212. The inner side of the suction pipe 211 is constructed with a suction channel 2111. The lower end of the suction pipe 211 has a suction port 2112 that communicates with the suction channel 2111. The suction port 2112 is the suction end of the suction mechanism 21. The upper end of the suction pipe 211 has a discharge port 2113 that communicates with the suction channel 2111. The discharge port 2113 is connected to a material pipeline outside the equipment so that the material in the ton bag 5 can be transported to the subsequent processing equipment or storage device through the suction channel 2111.

[0038] Further reference Figure 5 and Figure 6A sleeve 212 is fitted over the outside of the suction pipe 211. The space between the wall of the sleeve 212 and the wall of the suction pipe 211 forms a reinforcing channel 213. A reinforcing hole 2114 is provided on the wall of the suction pipe 211 near its lower end. A filter screen (not shown) is provided at the reinforcing hole 2114 to prevent material from entering the reinforcing channel 213. The reinforcing channel 213 is connected to the suction channel 2111 through the reinforcing hole 2114. There are multiple reinforcing holes 2114, and these holes are arranged circumferentially at intervals on the inner side of the lower end of the suction pipe 211. The upper end of the sleeve 212 is provided with multiple connection ports 214 that communicate with the reinforcing channel 213. The multiple connection ports 214 are used to communicate with the negative pressure vacuum system outside the equipment, so that negative pressure can be formed at the reinforcing hole 2114, which enhances the suction capacity of the suction port 2112 and avoids the suction port 2112 being blocked by materials or insufficient suction force when suctioning materials.

[0039] Continue to refer to Figure 5 and Figure 6 A support frame 215 is provided on the outer side of the lower end of the suction pipe 211. The support frame 215 extends downward beyond the suction port 2112 to open the bag opening of the ton bag 5 during suction. This design effectively prevents the bag opening of the ton bag 5 from being sucked onto the suction port 2112 during suction, thus preventing the suction port 2112 from being blocked due to the bag opening sticking together, and improving the reliability of equipment operation.

[0040] Further reference Figure 5 and Figure 6 A magnetic rod 216 is installed on the support frame 215, and the magnetic rod 216 is located directly below the suction port 2112. This arrangement allows the magnetic rod 216 to adsorb ferromagnetic materials contained in the material, thereby removing impurities and improving the purity of the material.

[0041] like Figure 7 and Figure 8As shown, the lifting mechanism 31 of this embodiment includes a second drive motor 311, a drive wheel 312, a driven wheel 313, a transmission belt 314, a second guide rod 315, and a second slider 316. The second drive motor 311 is disposed on the upper side of the frame body 11, with its rotation axis arranged along the length of the frame body 11. The drive wheel 312 and driven wheel 313 are respectively disposed on the upper and lower sides of the frame body 11, with the driven wheel 313 located directly below the drive wheel 312. The second drive motor 311 is correspondingly disposed to the drive wheel 312, and its rotation axis is connected to the drive. The transmission belt 314 is respectively sleeved on the drive wheel 312 and the driven wheel 313. The second guide rod 315 is arranged along the height direction of the frame body 11, with its two ends fixedly disposed on the upper and lower sides of the frame body 11. The second slider 316 is sleeved on the second guide rod 315 and fixedly disposed on the transmission belt 314. A connecting mechanism 32 is disposed on the second slider 316. The second drive motor 311 drives the drive wheel 312 to rotate, causing the conveyor belt to run along the height direction of the frame body 11, thereby causing the second slider 316 to move up and down along the height direction of the frame body 11, which in turn enables the connecting mechanism 32 to drive the ton bag 5 to move up and down along the height direction of the frame body 11, so as to raise or lower the ton bag 5.

[0042] Continue to refer to Figure 7 and Figure 8 The connecting mechanism 32 includes a hook 321 and a weighing sensor 322. The hook 321 is mounted on the second end of the second slider 316, and the weighing sensor 322 is mounted on the hook 321 to detect the load borne by the hook 321. This configuration enables the equipment to accurately monitor the weight change of the ton bag 5 during the material feeding process. It not only achieves real-time sensing and operational control of the ton bag 5's status but also provides data support for overload prevention and process metering, further improving the equipment's automation level and operational reliability.

[0043] The working principle of the ton bag suction device in this embodiment of the utility model is as follows: First, a pallet 6 loaded with ton bags 5 is fed into the inner space 111 of the frame body 11 through the first gantry gate 1121 or the second gantry gate 1131. During this process, the grating sensor at the gantry gate can detect whether a single layer of ton bags 5 or two layers of stacked ton bags 5 are entering; at the same time, the pallet detection device 47 can detect whether the pallet 6 is completely placed in the pallet space portion 1113. When it is detected that the pallet 6 is completely placed in the pallet space, the hooks 321 of each lifting component 3 are connected to the ton bags 5, and then the lifting mechanism 31 drives the ton bags 5 to rise. During this process, the ton bag 5 sensor can detect whether the ton bags 5 are normally raised to the preset height. When the ton bags 5 are normally raised to the preset height, the suction process is executed, so that the suction port 2112 of the suction pipe 211 is moved into the ton bag 5, so that the material in the ton bag 5 is transferred to the subsequent processing equipment or storage device by negative pressure suction. During this process, the weighing sensor 322 on the hook 321 can detect the weight change of the ton bag 5 in real time, thereby determining the current material suction progress. Finally, after the material suction process is completed, the suction port 2112 of the suction pipe 211 is removed from the ton bag 5, and the ton bag 5 is lowered to the initial position by the lifting mechanism 31, completing one work cycle.
