Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and in particular to a container bag feeding system. Background Technology

[0002] FIBCs, also known as bulk bags or jumbo bags, are medium-sized flexible transport packaging containers. They offer advantages such as moisture resistance, dust protection, radiation resistance, and robust safety, and possess sufficient structural strength for efficient material loading. They are convenient for transporting large quantities of bulk powdery materials and also feature simple structure, large capacity, light weight, foldability, small space occupation when empty, easy loading and unloading, and low price. When used with cranes or forklifts, they can achieve unitized transport. Due to their ease of loading, unloading, and handling, FIBCs have seen rapid development in recent years. FIBCs are generally made of polyester fibers such as polypropylene and polyethylene.

[0003] Currently, the industry generally uses manual operation of lifting equipment to transport the FIBCs to the corresponding area. After that, the FIBCs are cut open by hand with a knife before the material is fed in. However, this method has the problem of inaccurate metering and counting, which may slow down the work process. At the same time, manual cutting of FIBCs will generate too much dust on site, which may pose a risk to the occupational health of the workers and is not conducive to long-term safe operation. Summary of the Invention

[0004] The purpose of this invention is to provide a container bag feeding system that can replace manual feeding, automatically complete the unpacking, avoid repeated counting and monitoring by operators, reduce labor intensity, ensure accurate counting, and improve work efficiency; at the same time, it avoids direct exposure of dust to the workers' workspace, protects the workers' respiratory health, and can be carried out safely and effectively for a long time.

[0005] To achieve this objective, the present invention adopts the following technical solution: The FIBC (Flexible Intermediate Bulk Container) feeding system includes: The transmission module includes a double-speed chain for carrying and differentially driving the container bags; The identification module includes a scanning device and a counting device. The scanning device can identify and input the material parameters of the container bag. The scanning device is communicatively connected to the counting device, and the counting device can count the number of container bags passing through the scanning device. The unpacking module includes an unpacking machine and a receiving machine. The unpacking machine has a discharge port at its bottom, which is connected to the receiving machine. The unpacking machine is equipped with a fixing device and a cutting device inside. The fixing device can pick up the container bags on the speed-up chain, and the cutting device can cut open the container bags picked up by the fixing device so that the material inside the container bags falls into the discharge port.

[0006] As an optional technical solution for the container bag feeding system, the transmission module also includes a weighing device, which is communicatively connected to the counting device. The weighing device can weigh the material in the container bag and send it to the counting device.

[0007] As an optional technical solution for the container bag feeding system, the fixing device includes a hook trolley and a feeding position, and the double-speed chain can drive the container bag to the feeding position; the hook trolley is set on the top of the unpacking machine, and the hook trolley can move between the feeding position and the unloading port; the hook trolley includes a lifting gripper and a sensor, and the sensor can control the lifting gripper to contact and grab the container bag.

[0008] As an optional technical solution for the container bag feeding system, the fixing device also includes an auxiliary transport wheel belt, which can synchronously transport the container bag to the discharge port with the grab hook trolley.

[0009] As an optional technical solution for the container bag feeding system, the cutting device includes a cutting blade, which is at least located on both sides of the unpacking machine in front of the feeding port.

[0010] As an optional technical solution for the container bag feeding system, the unpacking module also includes a dust collector, the top of which is provided with a dust collection port, and the dust collector is connected to the dust collection port under negative pressure.

[0011] As an optional technical solution for the container bag feeding system, the unpacking module also includes a scraper separator. The discharge port is connected to the scraper separator, which has multiple discharge ports. Each of the multiple discharge ports is connected to a corresponding reactor of the receiving machine.

[0012] As an optional technical solution for the container bag feeding system, the unpacking machine also includes a striking device. The striking device is located above the feeding port and fixed to the inner wall of the unpacking machine. The striking device includes a telescopic arm and a striking arm connected to each other. The telescopic arm can extend or shorten within a preset range so that the striking arm repeatedly impacts the container bag located above the feeding port.

[0013] As an optional technical solution for the container bag feeding system, the bottom of the unpacking machine is provided with a bag dropping port, which is located behind the feeding port, and the fixing device can drop the container bag that has lost material into the bag dropping port.

[0014] As an optional technical solution for the FIBC feeding system, the FIBC feeding system also includes a waste bag processing module, which includes a fiber cutting machine, a washing machine and a baling machine. The bag drop outlet is connected to the fiber cutting machine, which can cut the FIBC that has lost material and transfer it to the washing machine and the baling machine in sequence.

[0015] The beneficial effects of this invention are: The FIBC (Flexible Intermediate Bulk Container) feeding system provided by this invention includes a transmission module, an identification module, and an unpacking module. The transmission module includes a double-speed chain for carrying FIBCs, which are then distributed at differential speeds via the chain. The identification module includes a scanning device and a counting device. When a FIBC passes through the identification module, the scanning device automatically scans and identifies the information code on the FIBC to confirm the specific composition and specifications of the material.

The FIBC feeding system can be integrated with the overall material production line to control on-demand material input. Material input is automatically counted, and operation automatically stops when a set value is reached, avoiding repeated monitoring and reducing labor intensity for operators.

[0016] Using machines to replace manual feeding, the FIBCs (Flexible Intermediate Bulk Containers) are conveyed to the unpacking machine via a high-speed chain conveyor. The unpacking module includes an unpacking machine and a receiving machine. The unpacking machine has a discharge port at its bottom, which connects to the receiving machine. The unpacking machine is equipped with a fixing device and a cutting device. Inside the enclosed unpacking machine, the fixing device automatically picks up the FIBCs from the high-speed chain, completing the automatic bag hanging process. The cutting device cuts open the FIBCs picked up by the fixing device, completing the automatic unpacking. This avoids direct dust exposure to the workers' workspace, protecting their respiratory health and allowing for safe and long-term operation. The material inside the FIBC falls into the discharge port and enters the receiving machine. The receiving machine communicates with an identification module, allowing for the matching of container numbers used for receiving materials. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0020] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0023] like Figure 1As shown, this invention discloses a container bag feeding system, including a transmission module, an identification module, and an unpacking module 10. The transmission module includes a double-speed chain, which carries and differentially drives the container bags 20. The identification module includes a scanning device and a counting device. The scanning device can identify and input the material parameters of the container bags 20. The scanning device is communicatively connected to the counting device, which can count the number of container bags 20 passing through the scanning device. The unpacking module 10 includes an unpacking machine 100 and a receiving machine. The bottom of the unpacking machine 100 is provided with a discharge port 101, which is connected to the receiving machine. The unpacking machine 100 is internally provided with a fixing device 110 and a cutting device. The fixing device 110 can pick up the container bags 20 on the double-speed chain, and the cutting device can cut open the container bags 20 picked up by the fixing device 110 so that the material inside the container bags 20 falls into the discharge port 101.

[0024] The aforementioned FIBC (Flexible Intermediate Bulk Container) feeding system is applied to the processing of large quantities of FIBCs 20, such as those containing MHP (nickel cobalt hydroxide) and cobalt intermediates. MHP is generally obtained from laterite nickel ore through high-pressure acid leaching (HPAL), or it can be produced from battery black powder. MHP is a grayish-green powder, soluble in water, and belongs to nickel intermediates. It is generally used to produce nickel sulfate, refined nickel cobalt hydroxide, nickel plates, and other products. Multiple FIBCs 20 containing MHP are placed on the feeding position of the conveyor module by a European-style overhead crane. The unhooking of the FIBCs 20 is first manually checked. After confirming that all FIBCs 20 are completely unhooked, the double-speed chain conveyor is started, and the identification module is activated. The FIBCs 20 are then fed to the unpacking machine 100 via differential speed distribution via the double-speed chain. The conveying process of the container bag 20 containing cobalt intermediate material is not much different from that of the container bag 20 containing MHP material. If the material is heavy, the container bag 20 can be sorted at a low position first, and a forklift can be used to place the container bag 20 at the unloading position. After it is placed, the material is lifted to the same height as the unpacking machine 100 by the elevator.

[0025] When the FIBC 20 on the speed-conveying conveyor passes the identification module, the scanning device can automatically scan and input the information code on the FIBC 20 through a barcode scanner to confirm the specific composition and specifications of the material. Simultaneously, the counting device automatically counts the number of FIBCs 20 passing through the scanning device, ensuring accurate counting and improving operational efficiency. The FIBC feeding system, integrated with the overall material production line, can control the feeding of materials on demand. Material input is automatically counted, and operation automatically stops when a set value is reached, avoiding repeated monitoring and reducing labor intensity. Using machines to replace manual feeding, the FIBC 20 is conveyed by the speed-conveying conveyor to the unpacking machine 100. Inside the enclosed unpacking machine 100, the fixing device 110 picks up the FIBC 20 from the speed-conveying conveyor, completing the automatic bag hanging. The cutting device can cut open the FIBC 20 picked up by the fixing device 110, completing the automatic unpacking. This avoids direct dust exposure to the workers' workspace, protecting their respiratory health and allowing for safe and long-term operation. The material inside the container bag 20 falls into the discharge port 101 and enters the receiving machine. The receiving machine is connected to the identification module and can be set to match the container number used for receiving.

[0026] Furthermore, the unpacking machine 100 is configured as a sealed container with an internal negative pressure state. The unpacking module 10 also includes a dust collector 200. The top of the unpacking machine 100 is provided with a dust collection port, and the dust collector 200 is connected to the dust collection port, which enables the unpacking machine 100 to generate a continuous negative pressure, collect excess dust through the dust collector 200, ensure the cleanliness of the inside of the unpacking machine 100, and prevent dust accumulation from affecting the service life of the internal devices of the unpacking machine 100.

[0027] In this embodiment, the transmission module also includes a weighing device, which is communicatively connected to the counting device. The weighing device can weigh the material in the container bag 20 and send it to the counting device to further verify the total amount of material and perform comprehensive process management.

[0028] Specifically, the fixing device 110 includes a hook trolley 1110 and a loading position, and the double-speed chain can drive the container bag 20 to the loading position; the hook trolley 1110 is set on the top of the unpacking machine 100, and the hook trolley 1110 can move between the loading position and the unloading port 101; the hook trolley 1110 includes a lifting gripper 1111 and a sensor, and the sensor can control the lifting gripper 1111 to contact and grab the container bag 20. After the container bag 20 enters the unpacking machine 100, the hook trolley 1110 is positioned above the container bag 20. The lifting gripper 1111 descends. When the lifting gripper 1111 contacts the container bag 20, it triggers a sensor to generate a signal, thereby controlling the lifting gripper 1111 to stop descending and causing the lifting gripper 1111 to open its hook and penetrate into the container bag 20. This can fix the container bag 20 in place, allowing the container bag 20 to move together with the hook trolley 1110 to the discharge port 101.

[0029] Furthermore, the fixing device 110 also includes an auxiliary transport wheel 1120. The auxiliary transport wheel 1120 can transport the container bag 20 to the discharge port 101 synchronously with the grab hook trolley 1110. The auxiliary transport wheel 1120 is used to bear part of the weight of the container bag 20, avoiding the risk of the container bag 20 being worn out midway due to excessive friction. At the same time, the grab hook trolley 1110 and the auxiliary transport wheel 1120 move forward together to transport the container bag 20, which can help reduce the stress on the grab hook trolley 1110, reduce driving energy consumption, and extend the service life of the grab hook trolley 1110.

[0030] In this embodiment, the cutting device includes a cutting blade 121, which is at least positioned on both sides of the unpacking machine 100 in front of the discharge port 101 to fully unpack the bulk bag 20. For example, the cutting blade 121 can be positioned on three sides inside the unpacking machine 100 to cut the bulk bag 20 on three sides. After the grabbing trolley 1110 reaches the upper part of the discharge port 101, it stops for a period of time, waiting for all the material to fall into the receiving machine.

[0031] Understandably, the unpacking machine 100 also includes a striking device 130, which is located above the discharge port 101 and fixed to the inner wall of the unpacking machine 100. The striking device 130 includes a telescopic arm 131 and a striking arm 132 connected to each other. The telescopic arm 131 can extend or retract within a preset range so that the striking arm 132 repeatedly impacts the container bag 20 located above the discharge port 101. The striking arm 132 strikes the container bag 20, causing all the residual material in the container bag 20 to fall out.

[0032] Optionally, the unpacking machine 100 is equipped with a bag drop opening 102 at its bottom, located behind the discharge port 101. The fixing device 110 can drop the container bag 20 that has lost material into the bag drop opening 102. The grabbing trolley 1110 carries the container bag 20 to the bag drop opening 102, and the grabbing hook of the lifting grabber 1111 retracts, discarding the waste container bag 20. The container bag feeding system also includes a waste bag processing module, which includes a fiber cutter, a washing machine, and a baling machine. The bag drop opening 102 is connected to the fiber cutter, which can cut the container bag 20 that has lost material and transfer it to the washing machine and the baling machine in sequence. The cut waste bags are automatically collected, washed by the washing machine, and then baled by the baling machine, completing the collection and sorting of waste for material recycling. This container bag feeding system has the characteristics of being green and environmentally friendly.

[0033] Specifically, the unpacking module 10 also includes a scraper separator. The discharge port 101 is connected to the scraper separator, which has multiple discharge ports. These discharge ports are connected to multiple reaction vessels of the receiving machine. Therefore, this container bag feeding system can be applied to production lines of various materials, making it more widely applicable.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
