Description

Technical Field

[0001] The present application relates to the technical field of material unpacking, and more specifically, to an automatic ton bag unpacking machine. Background Art

[0002] Ton bags, also known as flexible bulk bags, bulk bags, space bags, etc., are a type of medium-sized bulk container and a type of container unit equipment. In recent years, with the rapid development of the new energy lithium battery industry, the efficiency requirements for lithium battery production equipment have become increasingly higher. The main loading method for lithium battery material ton bags on the market is semi-automatic unpacking plus manual operation, and the loading efficiency is relatively low.

[0003] The unpacking machine is a machine used to dismantle ton bags of materials. At present, semi-automatic unpacking is often used for ton bags of lithium battery powder. Semi-automatic unpacking uses an overhead crane electric hoist or a forklift to transport the ton bags of lithium battery powder to the designated loading area, and then uses the overhead crane electric hoist of the semi-automatic unpacking machine to lift the ton bags of lithium battery powder and transport them to the inside of the feeding bin. The manual button closes the hatch, and the personnel operate the electric hoist to lower the ton bag, breaking the bottom of the ton bag to allow the lithium battery powder to flow out. After the lithium battery powder flows out, the manual button opens the hatch, and the overhead crane lifts out the waste empty bags, which are manually removed and sent to the waste bag area. This unpacking method is relatively cumbersome to operate, making it inconvenient to unpack ton bags of lithium battery powder, increasing the labor intensity of workers, and reducing the unpacking efficiency of the unpacking machine. At the same time, there is a lot of residual lithium battery powder after unpacking, which causes a certain amount of waste.

[0004] Without breaking the ton bag, when loading the ton bag of lithium battery materials, the operator needs to lift the ton bag of lithium battery materials with an electric hoist and transport it to the loading area. Inside the closed loading bin, the operator manually unties the rope tied to the mouth of the ton bag, and then operates the electric hoist to shake up and down to make the lithium battery materials in the ton bag flow out. After all the materials flow out, the closed bin is opened, and the empty ton bag is lifted out with an electric hoist, and then manually removed and transported to the waste bag area. The whole unpacking process is very cumbersome and inefficient. At the same time, the ton bag is heavy, and the operator needs to spend a lot of effort to untie the ton bag. The labor intensity is high, time-consuming and labor-intensive, which affects production efficiency. Therefore, there is an urgent need for an automatic unpacking machine to reduce the labor intensity of operators and improve production efficiency. Summary of the invention

[0041] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] refer to Figure 1 and Figure 2 , Figure 1 It is an overall perspective view of the automatic unpacking machine 1 according to the present application. Figure 2It is a perspective view of the automatic unpacking machine 1 according to the present application with the dust cover 8 and the automatic lifting door 9 removed. In one embodiment of the present application, the automatic unpacking machine 1 includes a conveying mechanism, a flipping and dumping mechanism 3, a bag breaking mechanism 4 and a material receiving mechanism 5, wherein the conveying mechanism cooperates with the flipping and dumping mechanism 3, and the conveying mechanism includes a first conveying line 21 and a driving device such as a motor. Specifically, the first conveying line 21 includes a roller conveying line, and the first conveying line 21 is configured to be driven by a motor to convey the ton bag 11 to the flipping and dumping mechanism 3. The flipping and dumping mechanism 3 is configured to clamp and fix the ton bag 11 and flip it. The bag breaking mechanism 4 can be located on the first side of the flipping and dumping mechanism 3, and the bag breaking mechanism is configured to break the clamped ton bag 11 from the side. The material receiving mechanism 5 can be located below the flipping and dumping mechanism 3. In a preferred embodiment, the material receiving mechanism 5 can be located directly below the flipping and dumping mechanism 3. According to the automatic bag unpacking machine 1 of the present application, it is possible to realize automatic conveying, clamping, bag breaking and receiving of materials in ton bags.

[0043] In addition, the automatic unpacking machine 1 according to the present application may also include a controller. The present application generally adopts a programmable logic controller (PLC) as the controller, which has the characteristics of high reliability, high flexibility and high scalability. The PLC can be programmed according to the specific needs of the unpacking machine to implement complex control logic and algorithms. The controller can be connected to various sensors for real-time monitoring of information such as the position and status of the ton bag 11. In addition, the controller is usually equipped with interfaces such as Ethernet and wireless communication, so that data exchange and linkage control can be performed with other devices. For example, the controller can be connected to equipment such as a conveying mechanism, a flipping and dumping mechanism 3, and a bag breaking mechanism 4 to achieve automatic control of the entire unpacking process.

[0044] In addition, the automatic unpacking machine 1 according to the present application may also include a plurality of sensors, such as photoelectric sensors, pressure sensors, and proximity sensors, etc. A pressure sensor may be provided on the first conveyor line 21, and the pressure sensor may sense the pressure on the first conveyor line 21, so that when there is no ton bag 11 on the first conveyor line 21, the controller may deactivate the motor driving the first conveyor line 21 based on the signal of the pressure sensor indicating that there is no ton bag 11, and when there is a ton bag 11 on the first conveyor line 21, the controller may enable the motor driving the first conveyor line 21 based on the signal of the pressure sensor indicating that there is a ton bag 11. In addition to the presence of a sensor on the first conveyor line 21, the overturning and dumping mechanism 3 may also be configured with a sensor, such as a photoelectric sensor and / or a proximity sensor, for detecting the presence and positioning of the ton bag 11.

[0045] In one embodiment of the present application, the overturning and dumping mechanism 3 includes a frame 31, an overturning assembly 32 and a clamping assembly 33, and the overturning and dumping mechanism 3 has the following features: Figure 3In the first initial position shown, in other words, in the first initial position, the flipping and dumping mechanism 3 is in a non-flipped state. Figure 3 and Figure 4 , Figure 3 It is a schematic diagram showing that the clamping assembly 33 of the overturning and dumping mechanism 3 of the automatic bag unpacking machine 1 of the present application clamps and fixes the ton bag 11 so that the bag breaking mechanism 4 can break the bag. Figure 4 It is a schematic diagram showing that the overturning assembly 32 of the overturning and dumping mechanism 3 of the automatic bag unpacking machine according to the present application overturns and dumps the clamped and broken ton bag 11.

[0046] In one embodiment of the present application, the clamping assembly 33 has a second initial position in a fully retracted state, and the clamping assembly 33 includes a plurality of clamping devices and a clamping device driver. When the overturning and dumping mechanism 3 is in the first initial position, the clamping assembly 33 is arranged on the frame 31 on the upper side of the overturning and dumping mechanism 3 and on the second side opposite to the first side where the bag breaking mechanism 4 is located. The clamping assembly 33 is a key component to ensure that the ton bag 11 is stably and safely positioned during the unpacking process, and is mainly used to prevent the movement and vibration of the ton bag 11 during the unpacking process, and to ensure the stability and accuracy of the unpacking operation. The clamping device driver is a driver used to drive the clamping device to generate a clamping force, and the driver generally includes pneumatic, electric, hydraulic, and the like.

[0047] The clamping device driver can drive multiple clamping devices to provide a clamping force sufficient to ensure that the ton bag 11 is firmly clamped. In one embodiment of the present application, a cylinder is used as a clamping device driver. As a transmission device, the cylinder can quickly respond to instructions from the controller and push multiple clamping devices to move quickly to the specified position to achieve accurate and efficient clamping. In one embodiment of the present application, after the flipping and dumping mechanism 3 flips back to the first initial position, the clamping assembly 33 retracts to the second initial position so that the above operation can be repeated for subsequent ton bags 11.

[0048] It is worth noting that the above-mentioned multiple clamping devices include at least two clamping devices. In one embodiment of the present application, the multiple clamping devices include four clamping devices, wherein two clamping devices are provided on the upper side of the flipping and dumping mechanism 3 and on the second side opposite to the first side where the bag breaking mechanism 4 is located. It should be understood that there may be more or fewer clamping devices. An example of a clamping device has a finger-shaped clamping head. It should be understood that the clamping device may include a clamping head having any other shape suitable for clamping the ton bag 11, such as a U-shaped or V-shaped clamping head, as long as the clamping head is capable of clamping the ton bag.

[0049] Additionally or optionally, the clamping assembly 33 may further include an intermediate transmission device, located between the clamping device and the clamping device driver, for transmitting the force generated by the clamping device driver to the clamping device, and changing the magnitude and direction of the force during the force transmission process, thereby being able to clamp the ton bag 11 more flexibly and stably.

[0050] In one embodiment of the present application, the above-mentioned flip assembly 32 includes a sprocket transmission structure, which includes a sprocket, a chain and a motor. The sprocket is meshed with the chain on the frame 31 of the flipping and dumping mechanism 3, so that the controller sends a control signal to the motor in response to the bag breaking mechanism 4 completing the bag breaking operation, so that the motor rotates the sprocket, thereby driving the entire flipping and dumping mechanism 3 to rotate slowly, such as Figure 4 As shown, the material in the ton bag 11 gradually flows out and flows to the material receiving mechanism 5 below. Afterwards, the controller sends a control signal to the motor in response to the overturning and dumping mechanism 3 being overturned by more than 90°, so that the motor alternately rotates forward and reverse within a certain angle, so that the overturning and dumping mechanism 3 swings back and forth several times, so that the material in the ton bag 11 is unloaded as much as possible. Then, the controller sends a control signal to the motor, so that the motor drives the overturning and dumping mechanism 3 to overturn back to the first initial position.

[0051] In one embodiment of the present application, Figure 3 and Figure 4 As shown in , the overturning and dumping mechanism 3 also includes a conveying correction device 2 installed on the frame 31. Specifically, the conveying correction device 2 includes, for example, a third conveyor line, and the third conveyor line may also include a roller conveyor line. In addition, the conveying correction device 2 may also include a sensor and a motor, the sensor is used to detect the position and posture of the ton bag 11, and the motor is used to drive the third conveyor line to move. In one embodiment of the present application, the sensor includes a photoelectric sensor, and the photoelectric sensor can be set in front of the ton bag 11, on the upper side, and on one or both sides of the left or right side.

[0052] The conveying deviation correction device 2 cooperates with the conveying mechanism when the overturning and dumping mechanism 3 is in the first initial position, and is used to convey the ton bag 11 conveyed by the conveying mechanism to the overturning and dumping mechanism 3 to the designated position on the third conveying line. After the ton bag 11 reaches the designated position, the photoelectric sensor detects the position and posture of the ton bag 11. When the posture of the ton bag 11 deviates too much from the posture required for the subsequent clamping component 33 to clamp, the motor of the conveying deviation correction device 2 can alternately rotate forward and reverse under the control of the controller, and the frequency of the motor's forward and reverse rotation can be controlled, so that when the motor rotates forward and reverse, the ton bag 11 on the conveyor belt driven by the motor will adjust its posture to a posture suitable for being clamped and fixed by the clamping component 33 through its own inertia. It should be understood that the ton bag 11 does not need to be completely straightened here, because the subsequent clamping component 33 and the bag breaking component 41 will force the ton bag 11 to be straightened in the process of squeezing the ton bag 11, so it is acceptable that the posture of the ton bag 11 is slightly skewed, which can reduce the complexity of the deviation correction system.

[0053] like Figure 2 As shown, the first conveyor line 21 is aligned with the conveying correction device 2 when the overturning and dumping mechanism 3 is in the first initial position, so that the ton bag 11 conveyed on the first conveyor line 21 can be seamlessly transferred to the conveying correction device 2. In one embodiment, the conveying correction device 2 is fixedly mounted on the frame 31 of the overturning and dumping mechanism 3, so that the conveying correction device 2 can be turned over together with the overturning and dumping mechanism 3, so that when the material in the ton bag 11 falls into the material receiving mechanism 5, there is no obstacle between the ton bag 11 and the material receiving mechanism 5.

[0054] like Figure 3 As shown in FIG. , the bag breaking mechanism 4 is arranged on one side of the flipping and dumping mechanism 3 and has the following Figure 3 The third initial position shown, in other words, the bag breaking mechanism 4 in the third initial position is in a fully retracted state. The bag breaking mechanism 4 includes a bag breaking assembly 41, which is configured to break the clamped ton bag 11 from the side when the ton bag 11 is clamped and fixed by the flipping and dumping mechanism 3, and then retreat to the third initial position, so as to repeat the above operation on the subsequent ton bag 11. The bag breaking assembly 41 includes a bag breaking component and a corresponding driver mechanically connected thereto. Specifically, in one embodiment, the bag breaking component is a cutter 42 and the corresponding driver is a cylinder (not shown). The cylinder can quickly respond to instructions from the controller, push the cutter 42 to move quickly to the specified position, and achieve accurate and efficient cutting. This fast response feature makes the bag breaking process of the ton bag 11 faster and improves work efficiency.

[0055] After the ton bag 11 is in the proper position defined by the overturning and dumping mechanism 3, the cylinder drives the cutter 42 to cut directly from the side of the ton bag 11. After completely breaking the entire side of the ton bag 11, the cylinder drives the cutter 42 to retreat to the position as shown in FIG. Figure 3 In one embodiment, the cutter 42 is in an "X" shape. The cutter 42 is made of high-quality steel, and after precision processing and special treatment, it has extremely high hardness, wear resistance and corrosion resistance, and can maintain a long service life even in harsh working environments.

[0056] The cylinder of the bag breaking assembly 41 is a rodless cylinder. The cutter 42 controlled by the cylinder moves more smoothly and with higher precision. This stability ensures the accuracy and consistency of cutting, further improving the bag breaking efficiency. Moreover, the high reliability and easy maintenance of the rodless cylinder also reduce the equipment failure rate and maintenance costs, and improve the safety of the workplace.

[0057] In the present application, a cylinder is used as a driver in both the clamping assembly 33 and the bag breaking assembly 41, and a cutter 42 controlled by a cylinder is used in the bag breaking mechanism 4 to reduce the need for manual operation and isolate the direct contact between the personnel and the cutting mechanism. This not only reduces the labor intensity of the workers, but also achieves the purpose of protecting the safety of the operators. In addition, the cylinder can well control the movement and stop of the cutter 42, effectively avoiding safety accidents caused by human operating errors. This automated control reduces the possibility of accidents and improves the safety of the workplace.

[0058] In addition, since the power of the cylinder comes from compressed air, its driving force is large and the friction is small. Therefore, the cutter 42 using the cylinder will not produce excessive friction during operation, reducing the wear and aging of the cutting mechanism, thereby extending the service life of the equipment. As an advanced transmission device, the cylinder has a more complex and precise internal structure and operation method. This complexity enables the cylinder to effectively avoid the problem of increased failure rate caused by factors such as old equipment, weak materials, and operating errors.

[0059] like Figure 3 and Figure 4 As best shown in FIG. 1 , the material receiving mechanism 5 is arranged below the overturning and dumping mechanism 3. In a preferred embodiment, the material receiving mechanism 5 is arranged directly below the overturning and dumping mechanism 3 so as to receive all the materials in the ton bag 11 to the greatest extent. In one embodiment, the material receiving mechanism 5 is, for example, a container in the shape of a square or round funnel. It should be understood that the material receiving mechanism 5 can be any container with a certain capacity and shape suitable for receiving the materials flowing out of the ton bag 11. The size of the opening of the material receiving mechanism 5 is designed to be able to receive substantially all the materials flowing out of the ton bag 11.

[0060] In another embodiment, the receiving mechanism 5 may further include a dust suction device and a filtering device, wherein the dust suction device is mainly used to collect and process the dust generated during the unpacking process. Its working principle is generally based on negative pressure dust suction technology. The dust generated during the unpacking process is sucked into the dust suction duct through the high-speed airflow generated by the fan, and transmitted to the receiving mechanism 5. The filtering device is mainly used to filter and clean the sucked dust to ensure that the exhausted air is clean and dust-free. Its working principle is generally based on the adsorption and interception effect of the filter material. The dust suction device and the filtering device together constitute a complete dust treatment system, which can effectively collect and process the dust generated during the unpacking process to ensure the cleanliness and dust-freeness of the operating environment. By adopting these two devices in the receiving mechanism 5, it is of great significance to improve the unpacking efficiency and reduce environmental pollution.

[0061] Return to reference Figure 2 In another embodiment of the present application, the automatic unpacking machine 1 further includes a waste bag recovery mechanism 6. By adding the waste bag recovery mechanism, the waste bags can be recovered for reuse. The waste bag recovery mechanism 6 is, for example, a box-shaped container as a whole. It should be understood that the waste bag recovery mechanism 6 can be any other container suitable for accommodating ton bags 11. The waste bag recovery mechanism 6 can be open. In an improved embodiment, the waste bag recovery mechanism 6 can be covered to further reduce dust pollution. It is worth noting that in the case of a cover, the cover of the waste bag recovery mechanism 6 can be controlled by a controller so that the cover can be opened and closed at the appropriate time to minimize dust leakage.

[0062] In this embodiment, the conveying mechanism further includes a second conveying line 22. After the overturning and dumping mechanism 3 is overturned back to the first initial position, the clamping assembly 33 is retracted, causing the discarded ton bags 11 to fall on the third conveying line of the conveying and correcting device 2, and the third conveying line conveys the discarded ton bags 11 to the second conveying line 22. The second conveying line 22 is configured to convey the discarded ton bags 11 to the waste bag recycling mechanism 6, and the discarded ton bags 11 can be collected in the waste bag recycling mechanism 6 and wait for further processing. Figure 2 As shown, in one embodiment, the second conveyor line 22 is also aligned with the conveyor deviation correction device 2 when the overturning and dumping mechanism 3 is in the first initial position, so that the conveyor deviation correction device 2 can seamlessly transfer the discarded ton bags 11 to the second conveyor line 22. Moreover, an example of the second conveyor line 22 may also include a roller conveyor line.

[0063] As described above, one or more of the first conveyor line 21, the second conveyor line 22 and the third conveyor line may include a roller conveyor line. Compared with conventional belt conveyor lines and chain conveyor lines, roller conveyor lines transmit articles through continuously rolling rollers, which ensures the stable and rapid advancement of articles on the conveyor line, thereby greatly improving the conveying efficiency. Compared with belt conveyor lines and chain conveyor lines, roller conveyor lines have a more efficient rolling mechanism when dealing with heavier articles, while belt conveyor lines have limited carrying capacity and the belts are easily worn. The roller conveyor line is very stable during operation, and articles are not easily damaged or overturned during transportation. This stability ensures the safety and integrity of articles during transportation, and the mechanical noise of the roller conveyor line is small, while the mechanical noise of the chain conveyor line is large, and the later maintenance requirements are high. In addition, the structure of the roller conveyor line is relatively simple, mainly consisting of a roller, a bracket, a drive device, etc., which makes it easy to maintain and maintain. At the same time, the modular design of the roller conveyor line also makes it more convenient to replace components.

[0064] Return to reference Figure 1 In one embodiment of the present application, the automatic unpacking machine 1 also includes a dust shield 8 and an automatic lifting door 9. In one embodiment, the dust shield 8 is used to enclose the unpacking area including the flipping and dumping mechanism 3, the bag breaking mechanism 4 and the material receiving mechanism 5. The dust shield 8 can detachably surround the unpacking area. The dust shield 8 is mainly used to protect the operator from dust. During the unpacking process, the material may generate a large amount of dust. If there are no effective protective measures, the dust may cause harm to the health of the operator. The dust shield 8 usually has the characteristics of fire resistance, corrosion resistance, and high temperature resistance. In addition, the surface of the dust shield 8 should be smooth and burr-free to ensure the safety of the operator.

[0065] The automatic lifting door 9 is arranged on the dust shield 8 and is configured to control the access to the unpacking area. Specifically, the automatic lifting door 9 is arranged on the dust shield 8 between the first conveyor line 21 and the overturning and dumping mechanism 3 and between the overturning and dumping mechanism 3 and the second conveyor line 22, and is located above the first conveyor line 21 and the second conveyor line 22 entering and exiting the dust shield 8. The automatic lifting door 9 is mainly used to control the isolation and connection between the internal and external environments of the automatic unpacking machine 1. During the unpacking process, the automatic lifting door 9 can be automatically opened or closed as needed to ensure the smooth progress of the materials during the conveying and unpacking process. At the same time, it can also prevent dust from escaping and keep the working environment clean. For example, when the ton bag 11 is fed into the dust shield 8 by the first conveyor line 21 and when the discarded ton bag 11 is sent out of the dust shield 8 by the third conveyor line, the automatic lifting door 9 is opened. When the ton bag 11 enters the dust shield 8, the two automatic lifting doors 9 are closed, thereby closing the entire unpacking area to prevent dust from escaping.

[0066] like Figure 3, Figure 4 and Figure 5 As shown in , in one embodiment of the present application, the automatic unpacking machine 1 may further include a blanking conveyor belt component 7. The blanking conveyor belt component 7 may be arranged below the overturning and dumping mechanism 3, and the blanking conveyor belt component 7 may include a driving device such as a motor and a conveying device such as a belt. The controller may start the motor of the blanking conveyor belt component 7 in advance in response to the clamping assembly 33 clamping and fixing the ton bag 11, so that when the bag breaking mechanism 4 cuts the ton bag 11 and when the overturning and dumping mechanism 3 is overturned, the blanking conveyor belt component 7 can convey a part of the material that escapes from the ton bag 11 and is scattered on the belt to the receiving mechanism 5. The blanking conveyor belt component 7 can be used to maximize the reception of materials by the receiving mechanism 5 and minimize the loss of materials during the unpacking process.

[0067] According to the multiple components of the automatic unpacking machine 1 of the present application (for example, the first conveyor line 21 and the second conveyor line 22 of the conveying mechanism; the flipping assembly 32, the clamping assembly 33 and the conveying correction device 2 of the flipping and dumping mechanism 3; the bag breaking assembly 41 of the bag breaking mechanism 4; the automatic lifting door 9; the blanking conveyor belt component 7; the cover of the covered waste bag recovery box, etc.) are automatically controlled by a controller, and the controller can be programmed in a conventional manner by a technician in this field. Since the present application is mainly used to protect mechanical devices, the present application will no longer explain the control method and circuit connection of the controller in detail.

[0068] The automatic unpacking machine according to the present application realizes the full automation of the ton bag unpacking process, greatly simplifies the operator's work flow during the unpacking process, and fundamentally reduces the operator's labor intensity compared to the semi-automatic process of the prior art. In addition, all unpacking actions are completed in a closed dustproof shield, which effectively prevents the leakage of dust, reduces the direct contact between the operator and the dust, reduces the risk of the operator inhaling dust, and maintains a relatively clean working environment for the operator. Moreover, by flipping and swinging back and forth through the flipping and dumping mechanism, the material in the ton bag can be unloaded as cleanly as possible. By including a blanking conveyor belt component, the loss of materials during the unpacking process can be minimized.
