Description

Technical Field

[0001] This application relates to the field of ton bag unloading technology, specifically to a ton bag unpacking device and unpacking system. Background Technology

[0002] Ton bags are a type of flexible transport packaging container with advantages such as large volume, light weight, high structural strength, easy loading and unloading, moisture protection, dust protection, and radiation resistance. They are typically used to transport large quantities of bulk powdery materials, such as various powdery raw materials required for battery manufacturing.

[0003] Once the bulk bags carrying powder are transported to the designated area, they need to be unpacked to remove and transfer the powder. Currently, the unpacking method typically involves manually operating a crane to lift the bags above the feeding port, followed by manual unpacking and unloading. This method has low automation, high labor costs, and exposes unpacking personnel to occupational health risks due to prolonged exposure to the powder environment. Furthermore, the unpacking and unloading process can easily lead to dust explosions and other safety accidents due to dust spillage. Utility Model Content

[0004] The main purpose of this application is to provide a ton bag unpacking device, which aims to solve the technical problems of low automation, high labor costs, threats to the health of unpacking personnel, and certain safety hazards in existing powder ton bag unpacking methods.

[0005] To achieve the above objectives, the ton bag unpacking device proposed in this application includes:

[0006] A fixed support, which is gantry-shaped, is used to place the target ton bag below the crossbeam structure of the fixed support;

[0007] A bag-breaking assembly is mounted on the crossbeam structure; the bag-breaking assembly is used to puncture the target ton bag to form a suction port at the top of the target ton bag;

[0008] A suction assembly is mounted on the crossbeam structure; the suction assembly extends into the suction port and is used to draw powder from inside the target ton bag into the target container under negative pressure.

[0009] The technical solution of this embodiment utilizes a bag-breaking component to puncture the top of the target ton bag, allowing the suction component to directly reach inside the bag and extract the powder, collecting and transferring it to the target container. This process eliminates the need for the powder to fall under gravity, making the powder transfer from the inside of the ton bag more controllable and avoiding severe dust generation during the falling process. This solution improves the automation of unpacking and retrieving powder from the ton bag, reduces labor costs, and minimizes powder spillage during unpacking and retrieving, thereby reducing the threat of dust to the health of operators and lowering the risk of dust explosions and other safety accidents.

[0010] In some embodiments, the ton bag unpacking device further includes a bag hanging assembly, which is mounted on the column structure of the fixed bracket; the bag hanging assembly includes a hook and a bag hanging drive device, the hook being connected to the bag hanging drive device; the bag hanging drive device is used to drive the hook to rotate to a first angle so that the hook passes through the mounting opening of the lifting strap of the target ton bag, thereby hooking the lifting strap onto the concave side of the hook.

[0011] By setting up a bag-hanging assembly, the automatic hanging operation of the target ton bag can be realized. The hook and the sling are used to limit the target ton bag and prevent it from twisting or shifting during the subsequent puncture and powder suction operation. This maintains the positional stability of the target ton bag and allows for efficient completion of the puncture and powder suction operation.

[0012] In some embodiments, the bag hanging assembly further includes a stop bar, which is disposed opposite to the concave side of the hook; when the hook is rotated to the first angle, the stop bar and the concave side of the hook enclose a hanging space.

[0013] By setting a stop bar, after the hook has completed the bag-hanging operation, the stop bar can block the opening of the hook, preventing the already hung sling from coming out of the opening and causing the target ton bag to fall.

[0014] In some embodiments, the bag hanging assembly further includes a limiting mechanism; when the hook rotates to the first angle, the movable part of the limiting mechanism extends and abuts against the hook to prevent the hook from rotating.

[0015] By setting a limiting mechanism, an additional limiting effect can be applied to the hook after the bag hanging operation is completed, preventing the hook from rotating on its own due to insufficient self-locking force of the bag hanging drive device or other external factors, which could lead to unstable hanging of the sling or even detachment.

[0016] In some embodiments, the ton bag unpacking device further includes a lifting component, which is mounted on the crossbeam structure and connected to the bag hanging component. The lifting component is used to drive the bag hanging component to rise after the sling is attached, so as to bring the top of the target ton bag into contact with the bag breaking component to complete the puncture.

[0017] By setting up a lifting component, the target ton bag can be moved upwards to the bag-breaking component after the bag hanging operation is completed, so that the bag can be punctured and broken. In this way, the lifting of the hooks can ensure that each sling is suspended on the corresponding hook. When the target ton bag is in a suspended state, it can be ensured that the powder inside the target ton bag is deposited to the bottom of the ton bag under the action of gravity, rather than being scattered in the corners of the target ton bag. This is more conducive to the subsequent powder suction operation, which can improve the fullness of powder suction and reduce the amount of powder residue in the target ton bag.

[0018] In some embodiments, the target ton bag has at least two oppositely arranged lifting straps, and the ton bag unpacking device includes at least two lifting components and at least two bag hanging components. The at least two lifting components are connected to the at least two bag hanging components in a one-to-one correspondence, and the at least two bag hanging components are used to hook the at least two lifting straps in a one-to-one correspondence.

[0019] Based on the independent drive of each sling of the target ton bag, the current posture of the target ton bag can be adjusted more flexibly. In practical applications, when the lifting component uses a drive device with a variable drive stroke, such as a servo motor, the target ton bag can be kept in a state of constant shaking or swaying by repeatedly changing the height position of each sling within a short period of time. This can prevent some powder from accumulating at the corners of the target ton bag, allowing the suction end of the suction component to fully contact the powder, thereby further improving the fullness of powder suction.

[0020] In some embodiments, the suction assembly includes a suction drive mechanism and a suction gun. The suction drive mechanism is mounted on the crossbeam structure and connected to the suction gun. The upper port of the suction gun is used to connect to the target container. The suction drive mechanism is used to drive the suction gun to move downward so that the lower port of the suction gun extends into the suction port to perform powder suction operation.

[0021] Before performing the powder suction operation on the target ton bag, the suction drive mechanism can drive the suction gun to move upward to a higher position to avoid interference between the suction gun and the target ton bag and the bag breaking component; after the bag breaking operation is completed, the suction drive mechanism can drive the suction gun to move downward until the lower end of the suction gun extends into the suction port, and then the suction gun can be used to perform negative pressure suction of the powder in the target ton bag.

[0022] In some embodiments, the bag-breaking assembly includes a bag-breaking blade tube that extends vertically and surrounds the suction gun. The lower end of the bag-breaking blade tube has a serrated structure for piercing the top of the target ton bag to form the suction port. The suction driving mechanism is used to drive the suction gun to move upward and be housed in the inner cavity of the bag-breaking blade tube.

[0023] By placing the suction gun within the surrounding area of ​​the bag-breaking knife tube, it is possible to conveniently house the suction gun within the inner cavity of the bag-breaking knife tube, avoiding interference with the puncture and bag-breaking operation of the serrated structure. On the other hand, it ensures that the suction gun is within the orthogonal projection range of the suction port formed by the puncture of the serrated structure, that is, to ensure that the suction port and the suction gun are directly opposite each other. This ensures that the lower end of the suction gun can accurately extend into the suction port and complete the powder suction operation after moving downward.

[0024] In some embodiments, the lower end face of the bag-breaking knife tube is provided with a plurality of serrated structures, and the plurality of serrated structures are arranged in a semi-encircling shape along the circumference.

[0025] By arranging multiple serrated structures into a semi-enclosed "C" shape, the serrated structure can avoid directly cutting off a portion of the target ton bag during puncture, thus preventing the waste material from being mixed into the powder and affecting the powder quality.

[0026] In some embodiments, the suction gun includes an inner pipe and an outer pipe. The upper port of the inner pipe is used to connect to the target container, and the lower port of the inner pipe is used to extend into the suction port for powder suction. The outer pipe covers the surface of the inner pipe, and a flow chamber is formed between the inner wall of the outer pipe and the outer wall of the inner pipe. An air supply hole is provided on the upper side of the outer pipe, and the air supply hole communicates with the flow chamber. An air inlet hole is provided on the lower side of the inner pipe, and the air inlet hole communicates with the flow chamber and the inner cavity of the inner pipe.

[0027] When the inner pipe becomes blocked during the powder extraction process, air can be supplied to the air inlet through the air supply device. The supplied gas passes through the flow chamber and the air inlet in sequence before reaching the inner cavity of the inner pipe. In this way, the air pressure can be used to clear the inner pipe, achieving the effect of air replenishment and pipe cleaning, and ensuring the smooth flow of the inner pipe.

[0028] In some embodiments, the suction assembly further includes an anti-clogging cover, which covers the lower port of the suction gun. The inner cavity of the anti-clogging cover is connected to the inner cavity of the suction gun. The surface of the anti-clogging cover is provided with a plurality of suction channels, which are connected to the inner cavity of the anti-clogging cover.

[0029] By limiting the size of the suction channel, large clumps of powder can be blocked, and the bag body of the target ton bag can be prevented from being directly sucked into the inner cavity of the suction gun, thus achieving a filtration effect and effectively preventing the suction gun from clogging.

[0030] In some embodiments, the suction drive mechanism includes a suction drive device and a transmission screw. The suction drive device is mounted on the crossbeam structure and connected to the transmission screw. The suction gun moves along the threaded helical surface of the transmission screw. The suction drive device is used to drive the transmission screw to rotate, thereby driving the suction gun to move up and down.

[0031] The transmission screw can convert rotary motion into linear motion. Thus, the suction drive device only needs to use a rotary motor or other rotary drive device that does not occupy too much height space. In addition, the suction drive device can use the deceleration effect of the transmission screw to drive the suction gun to move downward at a slower speed, which can avoid the problem of powder overflow caused by the lower end of the suction gun impacting the powder at a faster moving speed.

[0032] In some embodiments, the ton bag unpacking device further includes a barcode scanning component, which is mounted on the column structure of the fixed bracket and is used to scan the identification code on the target ton bag.

[0033] The barcode scanning component is electrically connected to the bag breaking component and the material suction component; the barcode scanning component is used to send a stop signal to the bag breaking component and the material suction component when the result of the barcode scanning operation is not successful, so as to trigger the bag breaking component and the material suction component to stop operating.

[0034] When the identification code on the target ton bag is incorrect or cannot be identified, that is, when the scanning operation fails, it can be determined that the current target ton bag is being dispensed incorrectly. At this time, the scanning component can automatically trigger the bag breaking component and the material suction component to stop performing subsequent operations by sending an electrical signal. This can ensure the accuracy of material dispensing and avoid irreversible consequences caused by performing puncture and bag breaking operations and powder suction operations when the material is dispensed incorrectly.

[0035] In some embodiments, the ton bag unpacking device further includes a prompting component, which is electrically connected to the barcode scanning component; the barcode scanning component is used to send an error signal to the prompting component when the result of the barcode scanning operation is unsuccessful, so as to trigger the prompting component to perform an alarm operation.

[0036] By setting up a prompt component, an alarm can be triggered to alert on-site personnel to intervene in a timely manner when the target ton bag is incorrectly placed, thereby improving the timeliness of response and preventing prolonged equipment downtime due to incorrect material placement.

[0037] This application also proposes an unpacking system, which includes a target ton bag and a ton bag unpacking device as described above; the target ton bag is placed below the crossbeam structure, the bag breaking component is used to puncture the top of the target ton bag to form a suction port, and the suction component is used to extend into the suction port to perform a powder suction operation.

[0038] The technical solution of this embodiment utilizes a bag-breaking component to puncture the top of the target ton bag, allowing the suction component to directly reach inside the bag and extract the powder, collecting and transferring it to the target container. This process eliminates the need for the powder to fall under gravity, making the powder transfer from the inside of the ton bag more controllable and avoiding severe dust generation during the falling process. This solution improves the automation of unpacking and retrieving powder from the ton bag, reduces labor costs, and minimizes powder spillage during unpacking and retrieving, thereby reducing the threat of dust to the health of operators and lowering the risk of dust explosions and other safety accidents.

[0039] In some embodiments, the target ton bag includes a ton bag body and a lifting strap; the two ends of the lifting strap are connected at intervals to the upper side of the ton bag body to form a mounting opening above the ton bag body for hanging the bag.

[0040] The sling has at least one fold, which is twisted 180°.

[0041] When there is at least one 180° twisted fold on the sling, the fold makes it easier for the sling to maintain a stable and upright state and prevent it from sagging. This allows the hook of the bag hanging assembly to pass through the hanging opening formed by the sling more smoothly, thereby improving the success rate of automatic bag hanging operation.

[0042] In some embodiments, the target ton bag further includes a waist belt that surrounds the upper edge of the ton bag body and is fitted to the surface of the lifting strap.

[0043] By setting up a waist belt, on the one hand, the shape of the upper edge of the ton bag body can be maintained, the structural strength of the upper part of the ton bag body can be enhanced, and the ton bag body is not easy to deform; on the other hand, it can also provide a certain protective support for the lifting strap, making it easier for the lifting strap to maintain a stable and upright state and not easy to sag, so that the hook of the bag hanging component can pass through the hanging opening formed by the lifting strap more smoothly, thereby improving the success rate of automatic bag hanging operation.

[0044] In some embodiments, the target ton bag includes an outer bag body, an inner bag body, and a sealing strip. The outer bag body is a woven bag, and the inner bag body is an aluminum-plastic bag. The outer bag body covers the surface of the inner bag body, and the top of the outer bag body has a material passage opening. The sealing strip is attached to the surface of the outer bag body by Velcro and seals the material passage opening. The bag-breaking assembly is used to puncture the top of the inner bag body after passing through the material passage opening to form the suction port.

[0045] By designing the target ton bag with a double-layer structure, the advantages of aluminum-plastic bags in terms of barrier properties, moisture resistance, and temperature resistance can be utilized to provide better moisture and dust protection for the internal powder. Simultaneously, the high tensile strength and impact resistance of woven bags can enhance the structural strength of the target ton bag, making it less prone to damage during transportation and handling. Furthermore, by opening a material passage at the top of the outer bag, the passage can be easily sealed using a Velcro-sealed cap during transportation. Once the target ton bag is transported to the unpacking and retrieval area below the beam structure, the operator can tear open the cap. The subsequent bag-breaking component only needs to puncture the inner bag, eliminating the need to puncture the outer bag, which is more prone to generating debris and carrying foreign objects. This effectively prevents product quality incidents caused by debris and foreign objects from puncturing and mixing into the powder.

[0046] In some embodiments, the bottom surface of the target ton bag is configured as a planar structure.

[0047] By setting the target ton bag to a flat bottom structure, the production process of the target ton bag can be simplified, the production cost of the target ton bag can be reduced, and the placement stability of the target ton bag can be improved. Attached Figure Description

[0069] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0072] Ton bags are a type of flexible transport packaging container with advantages such as large volume, light weight, high structural strength, easy loading and unloading, moisture protection, dust protection, and radiation resistance. They are typically used to transport large quantities of bulk powdery materials, such as various powdery raw materials required for battery manufacturing.

[0073] Once the bulk bags carrying powder are transported to the designated area, they need to be unpacked to remove and transfer the powder. Currently, the unpacking method typically involves manually operating a crane to lift the bags above the feeding port, followed by manual unpacking and unloading. This method has low automation, high labor costs, and exposes unpacking personnel to occupational health risks due to prolonged exposure to the powder environment. Furthermore, the unpacking and unloading process can easily lead to dust explosions and other safety accidents due to dust spillage.

[0074] Due to the aforementioned drawbacks of manual unpacking and material handling, the industry has begun to adopt automated methods for unpacking and handling powder ton bags. However, after investigation and research, the researchers of this application found that existing automated solutions generally use bottom-breaking to complete the unpacking and material handling. That is, after a robotic arm grabs the ton bag to a certain height, a blade is used to cut open the bottom of the ton bag, allowing the powder inside to fall out under gravity. Then, negative pressure suction or other methods are used to collect the fallen powder and transport it to the target area. This method also has the problem of serious dust generation during the material falling process, and there is a risk of dust explosion due to the uncontrollable spillage of powder.

[0075] To address the aforementioned issues and improve the automation of unpacking and unloading powder ton bags, thereby reducing labor costs and mitigating the risk of powder spillage, this application provides a ton bag unpacking device. Please refer to [link to relevant documentation]. Figure 1 The ton bag unpacking equipment includes:

[0076] Fixed bracket 1, fixed bracket 1 is gantry-shaped, and the crossbeam structure 11 of fixed bracket 1 is used to place target ton bag 2 below;

[0077] The bag-breaking assembly 3 is installed on the crossbeam structure 11; the bag-breaking assembly 3 is used to puncture the target ton bag 2 to form a suction port 211 at the top of the target ton bag 2.

[0078] Suction assembly 4 is installed on the crossbeam structure 11; suction assembly 4 is used to extend into suction port 211 and to suck the powder inside the target ton bag 2 into the target container under negative pressure.

[0079] In this embodiment, the fixed bracket 1 can be welded from several steel structural parts and sheet metal parts. The fixed bracket 1 includes a crossbeam structure 11 and two column structures 12. The left and right ends of the crossbeam structure 11 are respectively mounted on a column structure 12 to form a through channel below the crossbeam structure 11. This facilitates the transport of the target ton bag 2 to be unpacked to the unpacking and material handling area below the crossbeam structure 11 by using an automated transport device such as an AGV (Automated Guided Vehicle). The bag breaking assembly 3 may include a driving device and sharp components such as blades, serrations, and hooks for piercing. The driving device can drive the sharp components to pierce the target ton bag 2 from top to bottom through a corresponding transmission mechanism to form a suction port 211 at the top of the target ton bag 2, so that the powder loaded inside the target ton bag 2 can communicate with the outside through the suction port 211. The suction assembly 4 may include a drive device and a suction device for generating negative pressure. After the bag breaking assembly 3 completes the puncture and bag breaking operation, the drive device can drive the suction device through the corresponding transmission mechanism to extend into the target ton bag 2 from top to bottom through the suction port 211, so as to draw the powder in the target ton bag 2 into the target container outside under the action of negative pressure, thereby completing the powder taking and collection transfer.

[0080] Therefore, in this embodiment, after the bag-breaking component 3 punctures the top of the target ton bag 2, the suction component 4 can directly reach inside the target ton bag 2 to suck up the powder, collect the powder, and transfer it to the target container. The above operation process does not require the powder to fall under gravity, and the process of transferring the powder from inside the target ton bag 2 to the outside is more controllable, avoiding the problem of serious dust generation during the powder falling process. The above solution improves the automation level of the powder ton bag unpacking and material retrieval operation, reduces labor costs, and reduces the degree of powder spillage during the unpacking and material retrieval process, thereby reducing the threat of dust to the health of operators and reducing the risk of safety accidents such as dust explosions.

[0081] In some embodiments, refer to Figure 1 , Figure 2 and Figure 9 The ton bag unpacking equipment also includes a bag hanging assembly 5, which is installed on the column structure 12 of the fixed bracket 1. The bag hanging assembly 5 includes a hook 51 and a bag hanging drive device 52. The hook 51 is connected to the bag hanging drive device 52. The bag hanging drive device 52 is used to drive the hook 51 to rotate to a first angle so that the hook 51 passes through the mounting opening of the lifting strap 22 of the target ton bag 2, thereby hooking the lifting strap 22 onto the concave side of the hook 51.

[0082] The lifting straps 22 of the target ton bag 2 are usually set to multiple and distributed on the upper side of the target ton bag 2. Taking two lifting straps 22 as an example, the two lifting straps 22 are usually distributed on opposite sides of the upper side of the target ton bag 2. When the AGV (Automated Guided Vehicle) or other automatic transportation device transports the target ton bag 2 to be unpacked to the unpacking and material picking area below the crossbeam structure 11, the two lifting straps 22 are respectively opposite to the two column structures 12 of the fixed bracket 1. At this time, the bag hanging assembly 5 installed on the column structure 12 can conveniently perform automatic bag hanging operation on the corresponding lifting straps 22.

[0083] Specifically, each sling 22 is as follows Figure 9 The enclosure shown forms a mounting opening, with hook 51 positioned as follows: Figure 2 The arc-shaped structure shown has a hook 51 whose first end is connected to the bag-hanging drive device 52. During the process of the target ton bag 2 entering the unpacking and material-retrieving area, the position of the hook 51 does not obstruct the lifting strap 22. After the target ton bag 2 is in place, the bag-hanging drive device 52 can drive the hook 51 to rotate around its first end, so that the second end of the hook 51 passes laterally through the loading opening of the lifting strap 22. When the hook 51 rotates to the first angle, the middle part of the hook 51 has completely passed through the loading opening. At this time, the upper part of the lifting strap 22 is hooked onto the concave side of the middle part of the hook 51, thus realizing the automatic bag-hanging operation of the target ton bag 2. The bag-hanging drive device 52 can be a rotary cylinder, etc., and is not limited here.

[0084] Based on the above settings, the automatic bag hanging operation of the target ton bag 2 can be realized. The hook 51 and the sling 22 are used to limit the target ton bag 2, so as to prevent the target ton bag 2 from twisting or shifting during the subsequent puncture and bag breaking operation and powder suction operation, and maintain the positional stability of the target ton bag 2. Thus, the puncture and bag breaking operation and powder suction operation can be completed efficiently.

[0085] In some embodiments, refer to Figure 1 , Figure 2 and Figure 9 The bag hanging assembly 5 also includes a stop bar 53, which is disposed opposite to the concave side of the hook 51; when the hook 51 is rotated to the first angle, the stop bar 53 and the concave side of the hook 51 enclose and form a hanging space.

[0086] Specifically, the first end of the hook 51 is rotatably connected to the column structure 12 directly or indirectly, and the first end of the stop bar 53 is also directly or indirectly connected to the column structure 12. When the hook 51 rotates to the first angle under the drive of the bag-hanging drive device 52, the second end of the hook 51 abuts against or has a slight gap with the second end of the stop bar 53. At this time, the stop bar 53 and the concave side of the hook 51 enclose a hanging space, and the lifting strap 22 of the target ton bag 2 passes through this hanging space. By setting the stop bar 53, after the hook 51 completes the bag-hanging operation, the stop bar 53 can block the opening of the hook 51, preventing the lifting strap 22 that has been hung from coming out of the opening and causing the target ton bag 2 to fall.

[0087] In some embodiments, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 The bag assembly 5 also includes a limiting mechanism 54; when the hook 51 rotates to the first angle, the movable part of the limiting mechanism 54 extends and abuts against the hook 51 to prevent the hook 51 from rotating.

[0088] By setting a limiting mechanism 54, an additional limiting effect can be provided on the hook 51 after the bag hanging operation is completed, preventing the hook 51 from rotating independently due to insufficient self-locking force of the bag hanging drive device 52 or other external factors, which could lead to unstable attachment or even detachment of the sling 22. Specifically, taking a cylinder as an example, the piston of the cylinder constitutes the moving part of the limiting mechanism 54, and the first end of the hook 51 can be... Figure 3 and Figure 4 The corresponding limiting hole 511 is provided as shown. The piston of the cylinder can be inserted into the limiting hole 511 after it is extended, so as to achieve a stable limiting of the hook 51.

[0089] Preferably, the limiting mechanism 54 can be electrically connected to the bag-hanging drive device 52 directly or indirectly. When the bag-hanging drive device 52 drives the hook 51 to rotate to the first angle, it can trigger the limiting mechanism 54 to perform a limiting operation by sending an electrical signal. For example, both the limiting mechanism 54 and the bag-hanging drive device 52 can be electrically connected to a controller. When the controller receives the rotation signal sent by the bag-hanging drive device 52, it can send a limiting drive signal to the limiting mechanism 54 to trigger the movable part of the limiting mechanism 54 to extend and abut against the hook 51. Based on this electrical signal driving method, the bag-hanging operation and the limiting operation can be completed automatically without manual intervention, and the tightness and accuracy of the action coordination can be improved.

[0090] In some embodiments, refer to Figure 1The ton bag unpacking equipment also includes a lifting component 6, which is installed on the crossbeam structure 11 and connected to the bag hanging component 5. The lifting component 6 is used to drive the bag hanging component 5 to rise after the lifting strap 22 is attached, so as to drive the top of the target ton bag 2 to contact the bag breaking component 3 and complete the puncture.

[0091] By setting up the lifting component 6, the target ton bag 2 can be moved upwards to the bag breaking component 3 after the bag hanging operation is completed, so that the bag breaking operation can be completed. In this way, the lifting of the hook 51 can ensure that each lifting strap 22 is suspended on the corresponding hook 51. When the target ton bag 2 is in a suspended state, it can be ensured that the powder in the target ton bag 2 is deposited to the bottom of the ton bag under the action of gravity, rather than being scattered in the corners of the target ton bag 2. This is more conducive to the subsequent powder suction operation, which can improve the fullness of powder suction and reduce the amount of powder residue in the target ton bag 2. The lifting component 6 may include a drive device such as a servo motor. The drive device can be installed on the crossbeam structure 11 and drive the bag hanging component 5 below to complete the lifting operation through transmission devices such as transmission chains and transmission belts.

[0092] In some embodiments, refer to Figure 1 and Figure 9 The target ton bag 2 has at least two oppositely arranged lifting straps 22. The ton bag unpacking device includes at least two lifting components 6 and at least two bag hanging components 5. The at least two lifting components 6 are connected to the at least two bag hanging components 5 in a one-to-one correspondence. The at least two bag hanging components 5 are used to hang the at least two lifting straps 22 in a one-to-one correspondence.

[0093] In this embodiment, each sling 22 on the target ton bag 2 is equipped with a separate bag hanging assembly 5 and a lifting assembly 6. This allows each sling 22 to be driven independently. For example, one sling 22 can be pulled upwards to a first height position, and another sling 22 can be pulled upwards to a second height position. There can be a height difference between the first and second height positions. Based on this driving method, the current posture of the target ton bag 2 can be adjusted more flexibly. In practical applications, when the lifting assembly 6 uses a drive device with an indefinite drive stroke, such as a servo motor, the target ton bag 2 can be kept in a state of continuous shaking or swaying by repeatedly changing the height position of each sling 22 within a short period of time. This can prevent some powder from accumulating at the corners of the target ton bag 2, allowing the suction end of the suction assembly 4 to fully contact the powder, thereby further improving the fullness of powder suction.

[0094] In some embodiments, refer to Figure 1 and Figure 5The suction assembly 4 includes a suction drive mechanism 41 and a suction gun 42. The suction drive mechanism 41 is mounted on the crossbeam structure 11 and is connected to the suction gun 42. The upper port of the suction gun 42 is used to connect to the target container. The suction drive mechanism 41 is used to drive the suction gun 42 to move downward so that the lower port of the suction gun 42 extends into the suction port 211 to perform powder suction operation.

[0095] Specifically, the upper port of the suction gun 42 can be connected to the negative pressure device and the target container through a corresponding pipe. Before performing the powder suction operation on the target ton bag 2, the suction drive mechanism 41 can drive the suction gun 42 to move upward to a higher position to avoid the suction gun 42 interfering with the target ton bag 2 and the bag breaking component 3; after the bag breaking operation is completed, the suction drive mechanism 41 can drive the suction gun 42 to move downward until the lower port of the suction gun 42 extends into the suction port 211, and then the suction gun 42 can be used to perform negative pressure suction of the powder in the target ton bag 2.

[0096] The material suction drive mechanism 41 may include a drive device and a transmission mechanism used in conjunction with it, which are not limited here.

[0097] In some embodiments, refer to Figure 1 and Figure 5 The bag breaking assembly 3 includes a bag breaking knife tube 31, which extends vertically and surrounds the suction gun 42. The lower end of the bag breaking knife tube 31 is provided with a serrated structure 311, which is used to puncture the top of the target ton bag 2 to form a suction port 211. The suction driving mechanism 41 is used to drive the suction gun 42 to move upward and be housed in the inner cavity of the bag breaking knife tube 31.

[0098] Specifically, a clearance through hole can be opened on the crossbeam structure 11 in the vertical direction, the upper end of the bag-breaking knife tube 31 can be installed on the lower side of the crossbeam structure 11, the inner cavity of the bag-breaking knife tube 31 is connected to the clearance through hole, the suction drive mechanism 41 is installed on the upper side of the crossbeam structure 11, and the suction drive mechanism 41 can drive the tubular suction gun 42 to move up and down in the clearance through hole and the inner cavity of the bag-breaking knife tube 31.

[0099] Based on the above settings, before performing the powder suction operation on the target ton bag 2, the suction drive mechanism 41 can drive the suction gun 42 to move upward until the suction gun 42 is completely housed in the inner cavity of the bag-breaking knife tube 31, so as to avoid the suction gun 42 interfering with the target ton bag 2 entering the unpacking and material-taking area; then the hanging bag assembly 5 can be used to hang the lifting strap 22 of the target ton bag 2; after the bag hanging operation is completed, the lifting assembly 6 drives the target ton bag 2 to move upward until the top of the target ton bag 2 contacts the serrated structure 311 to complete the puncture and bag-breaking operation; finally, the suction drive mechanism 41 drives the suction gun 42 to extend downward from the lower end of the bag-breaking knife tube 31 until the lower port of the suction gun 42 extends into the suction port 211 and completes the powder suction operation.

[0100] In this embodiment, the suction gun 42 is placed in the surrounding area of ​​the bag-breaking knife tube 31. On the one hand, this makes it easy to store the suction gun 42 in the inner cavity of the bag-breaking knife tube 31, avoiding interference of the suction gun 42 with the piercing and bag-breaking operation of the serrated structure 311. On the other hand, it ensures that the suction gun 42 is within the orthogonal projection range of the suction port 211 formed by the piercing of the serrated structure 311, that is, it ensures that the suction port 211 is directly opposite the suction gun 42. This ensures that the lower end of the suction gun 42 can accurately extend into the suction port 211 and complete the powder suction operation after moving downward.

[0101] In some embodiments, refer to Figure 1 and Figure 5 The lower end face of the bag-breaking knife tube 31 is provided with multiple serrated structures 311, which are arranged in a semi-enclosed shape along the circumference. Specifically, the multiple serrated structures 311 are arranged to form a semi-enclosed "C" shape, which avoids the serrated structures 311 directly cutting off a part of the target ton bag 2 during puncture, thereby avoiding the problem of the waste material that is cut off being mixed into the powder and affecting the quality of the powder.

[0102] In some embodiments, refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 The suction gun 42 includes an inner pipe 421 and an outer pipe 422. The upper port of the inner pipe 421 is used to connect to the target container, and the lower port of the inner pipe 421 is used to extend into the suction port 211 for powder suction operation. The outer pipe 422 covers the surface of the inner pipe 421. The inner wall of the outer pipe 422 and the outer wall of the inner pipe 421 form a flow chamber 4221. An air supply hole 4222 is provided on the upper side of the outer pipe 422, which is connected to the flow chamber 4221. An air inlet hole 4211 is provided on the lower side of the inner pipe 421, which is connected to the flow chamber 4221 and the inner cavity of the inner pipe 421.

[0103] In this embodiment, the upper port of the inner pipe 421 can be connected to the negative pressure device and the target container through a corresponding pipe. Under normal working conditions, the powder is mainly sucked through the inner pipe 421, so that the powder in the target ton bag 2 reaches the target container through the inner pipe 421 under negative pressure. The outer pipe 422 covers the surface of the inner pipe 421, and the upper and lower ends of the outer pipe 422 are sealed to the outer wall of the inner pipe 421. This forms a flow chamber 4221 surrounding the inner pipe 421. The air supply holes 4222 can be configured as one or more and arranged circumferentially along the outer pipe 422. The air inlet holes 4211 can also be configured as one or more and arranged circumferentially along the inner pipe 421. Based on this configuration, when the inner pipe 421 becomes blocked during powder suction, air can be supplied to the air supply holes 4222 through the air supply device. The supplied gas passes through the flow chamber 4221 and the air inlet holes 4211 in sequence and reaches the inner cavity of the inner pipe 421. In this way, the air pressure can be used to clear the inner pipe 421, achieving the effect of air supply and pipe cleaning, and ensuring the smooth flow of the inner pipe 421.

[0104] In some embodiments, refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The suction assembly 4 also includes an anti-sucking cover 43, which covers the lower port of the suction gun 42. The inner cavity of the anti-sucking cover 43 is connected to the inner cavity of the suction gun 42. Multiple suction channels are opened on the surface of the anti-sucking cover 43, and the multiple suction channels are connected to the inner cavity of the anti-sucking cover 43.

[0105] In this embodiment, by limiting the size of the suction channel, large clumps of powder with a large volume can be blocked, and the bag body of the target ton bag 2 can be prevented from being directly sucked into the inner cavity of the suction gun 42, thereby achieving a filtering effect and effectively preventing the suction gun 42 from becoming blocked.

[0106] In one exemplary embodiment, the anti-suction hood 43 can be formed by connecting multiple strip-shaped components in a certain arrangement, and the gaps between the multiple strip-shaped components form a suction channel; specifically as follows: Figure 8As shown, the anti-suction hood 43 may include a first annular member 431, a second annular member 432, a first straight member 433, and a plurality of second straight members 434. The diameter of the first annular member 431 is smaller than the diameter of the second annular member 432, and the first annular member 431 is located above the second annular member 432. The two ends of the first straight member 433 are respectively connected to the opposite sides of the second annular member 432 to divide the enclosed area of ​​the second annular member 432 into two semi-circular areas. The first annular member 431 and the second annular member 432 are connected by a plurality of second straight members 434 arranged circumferentially to form a funnel. The structure is as follows: Taking the suction gun 42, which includes the inner pipe 421 and the outer pipe 422 in the above embodiment, as an example, the opening formed by the first annular member 431 is connected to the lower port of the inner pipe 421. The multiple fan-shaped openings arranged circumferentially between the first annular member 431, the second straight member 434, and the second annular member 432 constitute suction channels. The two semi-circular areas formed between the second annular member 432 and the first straight member 433 also constitute suction channels. In the actual suction process, the powder in the target ton bag 2 can enter the inner cavity of the inner pipe 421 through the above multiple suction channels under negative pressure.

[0107] In some embodiments, refer to Figure 1 and Figure 5 The material suction drive mechanism 41 includes a material suction drive device 411 and a transmission screw 412. The material suction drive device 411 is mounted on the crossbeam structure 11 and is connected to the transmission screw 412. The material suction gun 42 moves along the threaded helical surface of the transmission screw 412. The material suction drive device 411 is used to drive the transmission screw 412 to rotate, so as to drive the material suction gun 42 to move up and down.

[0108] The transmission screw 412 can convert rotary motion into linear motion. Thus, the suction drive device 411 only needs to use a rotary motor or other rotary drive device that does not occupy too much height space. Furthermore, the suction drive device 411 can use the deceleration effect of the transmission screw 412 to drive the suction gun 42 to move downward at a slower speed, which can avoid the problem of powder overflow caused by the lower end of the suction gun 42 impacting the powder at a faster moving speed.

[0109] Preferably, refer to Figure 5 The suction assembly 4 also includes a dust cover 44, which can be installed at the connection gap between the suction drive device 411 and the transmission screw 412. The dust cover 44 can also be installed at the connection gap between the suction gun 42 and the transmission screw 412, so as to prevent the suctioned powder from overflowing from the gap and to prevent external impurities from entering from the gap and contaminating the powder.

[0110] In some embodiments, refer to Figure 1 The ton bag unpacking equipment also includes a barcode scanning component 7, which is installed on the column structure 12 of the fixed bracket 1. The barcode scanning component 7 is used to scan the identification code on the target ton bag 2.

[0111] The barcode scanning component 7 is electrically connected to the bag breaking component 3 and the material suction component 4. The barcode scanning component 7 is used to send a stop signal to the bag breaking component 3 and the material suction component 4 when the result of the barcode scanning operation is not passed, so as to trigger the bag breaking component 3 and the material suction component 4 to stop operating.

[0112] In practical applications, each target ton bag 2 is equipped with a different identification code, which can be a barcode or a QR code. When the target ton bag 2 is transported to the unpacking and material handling area below the beam structure 11 by an AGV or other automated transport device, the scanning component 7 can scan the identification code on the side of the target ton bag 2. If the identification code on the target ton bag 2 is incorrect or cannot be recognized, that is, if the scanning operation results in failure, it can be determined that the current target ton bag 2 has been incorrectly placed. At this time, the scanning component 7 can automatically trigger the bag breaking component 3 and the material suction component 4 to stop performing subsequent operations by sending an electrical signal. This can ensure the accuracy of material feeding and avoid irreparable consequences caused by performing puncture and bag breaking operations and powder suction operations when the material feeding is incorrect.

[0113] In some embodiments, refer to Figure 1 The ton bag unpacking equipment also includes a prompting component (not shown in the figure), which is electrically connected to the barcode scanning component 7. The barcode scanning component 7 sends an error signal to the prompting component when the scanning operation fails, triggering an alarm operation. This alarm operation alerts on-site personnel to intervene promptly, improving response timeliness and preventing prolonged equipment downtime due to incorrect material feeding. The prompting component can use alarm lights, buzzers, or other devices that emit alarm signals through sound, light, images, or text; no limitation is made here.

[0114] Specifically, the barcode scanning component 7 can be electrically connected to the bag breaking component 3, the material suction component 4, and the prompting component via the controller. The barcode scanning component 7 has a pre-stored correct target identification code. When the barcode scanning component 7 obtains the identification code image on the side of the target ton bag 2 through the barcode scanning operation, it will compare the identification code image with the pre-stored target identification code. If the comparison results are consistent, it is determined that the feeding is correct, and the barcode scanning component 7 will not interfere with subsequent operations. However, if the comparison results are inconsistent, it indicates that the feeding is incorrect. At this time, the barcode scanning component 7 sends an error signal to the controller. After receiving the error signal, the controller will send a stop signal to the bag breaking component 3 and the material suction component 4, and at the same time send an alarm signal to the prompting component to trigger the bag breaking component 3 and the material suction component 4 to stop performing subsequent operations, and trigger the prompting component to perform an alarm operation.

[0115] This application also provides an unpacking system; please refer to [link / reference]. Figures 1 to 10 The unpacking system includes a target ton bag 2 and a ton bag unpacking device in any of the above embodiments; the target ton bag 2 is placed below the crossbeam structure 11, the bag breaking component 3 is used to puncture the top of the target ton bag 2 to form a suction port 211, and the suction component 4 is used to extend into the suction port 211 to perform powder suction operation.

[0116] For specific details regarding the setup of the ton bag unpacking equipment, please refer to the above embodiments. Since this unpacking system employs all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments. Specifically, after the bag-breaking component 3 punctures the top of the target ton bag 2, the suction component 4 can directly penetrate into the target ton bag 2 to suck up the powder, collecting and transferring the powder to the target container. This operation eliminates the need for the powder to fall under gravity, making the process of transferring the powder from inside the target ton bag 2 to the outside more controllable and avoiding the problem of severe dust generation during the powder falling process. The above solution improves the automation level of the powder ton bag unpacking and material retrieval operation, reduces labor costs, and reduces the degree of powder spillage during the unpacking and material retrieval process, thereby reducing the threat of dust to the health of operators and lowering the risk of safety accidents such as dust explosions.

[0117] In some embodiments, refer to Figure 9 The target ton bag 2 includes a ton bag body 21 and a lifting strap 22; the two ends of the lifting strap 22 are connected at intervals to the upper side of the ton bag body 21 to form a hanging opening above the ton bag body 21 for hanging bag operation.

[0118] The sling 22 has at least one fold 221, which is twisted 180°.

[0119] When there is at least one fold 221 with a 180° twist on the sling 22, the fold 221 makes it easier for the sling 22 to maintain a stable and upright state and prevents it from sagging. This allows the hook 51 of the bag hanging assembly 5 to pass through the hanging opening formed by the sling 22 more smoothly, thereby improving the success rate of automatic bag hanging operation.

[0120] In some embodiments, refer to Figure 9 The target ton bag 2 also includes a waist belt 23, which is arranged around the upper edge of the ton bag body 21 and is attached to the surface of the lifting strap 22.

[0121] By setting the waist belt 23, on the one hand, the shape of the upper edge of the ton bag body 21 can be maintained, the structural strength of the upper part of the ton bag body 21 can be enhanced, and the ton bag body 21 is not easy to deform; on the other hand, it can also provide a certain protective support for the lifting strap 22, making it easier for the lifting strap 22 to maintain a stable upright state and not easy to sag, so that the hook 51 of the bag hanging assembly 5 can pass through the hanging opening formed by the lifting strap 22 more smoothly, thereby improving the success rate of automatic bag hanging operation.

[0122] In some embodiments, refer to Figure 9 The target ton bag 2 includes an outer bag body (not shown in the figure), an inner bag body (not shown in the figure), and a sealing strip 24. The outer bag body is a woven bag, and the inner bag body is an aluminum-plastic bag. The outer bag body covers the surface of the inner bag body. The top of the outer bag body is provided with a material passage opening. The sealing strip 24 is attached to the surface of the outer bag body by Velcro and seals the material passage opening. The bag breaking component 3 is used to puncture the top of the inner bag body after passing through the material passage opening to form a suction port 211.

[0123] By setting the target ton bag 2 to a double-layer structure, the advantages of aluminum-plastic bags in terms of barrier properties, moisture resistance and temperature resistance can be used to better prevent moisture and dust from the powder inside. At the same time, the high tensile strength and impact resistance of woven bags can be used to improve the structural strength of the target ton bag 2, making the target ton bag 2 less prone to damage during transportation and handling.

[0124] For the double-layered target ton bag 2, if both the outer and inner layers are punctured simultaneously during the puncture and breaking process, the resulting debris and foreign matter carried by the bag can easily mix into the powder, potentially leading to product quality issues. To address this problem, this embodiment features a material passage opening at the top of the outer layer. During the transport of the target ton bag 2, the material passage opening can be easily sealed using a Velcro-attached sealing strip 24. Once the target ton bag 2 is transported to the unpacking and material handling area below the beam structure 11, the operator can tear open the sealing strip 24. The subsequent bag-breaking component 3 only needs to puncture the inner layer, eliminating the need to puncture the outer layer, which is more prone to generating debris and carrying foreign matter. This effectively prevents product quality issues caused by debris and foreign matter mixed into the powder during puncture.

[0125] In some embodiments, refer to Figure 9 The bottom surface of target ton bag 2 is set as a flat structure.

[0126] Specifically, since the solution of this application does not require puncturing the bottom of the target ton bag 2, the target ton bag 2 can be set as a flat bottom structure without considering the bag breaking requirements. This simplifies the production process of the target ton bag 2, reduces the production cost of the target ton bag 2, and improves the placement stability of the target ton bag 2.

[0127] Based on the improvements to the unpacking system in the above embodiments, referring to... Figure 1 and Figure 10 The complete unpacking and material handling process of target ton bag 2 in this unpacking system is as follows:

[0128] The target ton bag 2 to be unpacked is placed on the pallet 8, and an automated transport device such as an AGV (Automated Guided Vehicle) transports the pallet 8 to the unpacking and material handling area below the beam structure 11. After the target ton bag 2 enters the unpacking and material handling area with the pallet 8, the barcode scanning component 7 scans the identification code on the side of the target ton bag 2. If the scanning result shows that the target ton bag 2 has been correctly placed, the bag hanging component 5 begins to automatically attach the various straps 22 of the target ton bag 2. After the automatic bag hanging operation is completed, the lifting component 6 drives the bag hanging component 5 to move upwards, thereby moving the target ton bag 2 upwards until the top of the target ton bag 2 contacts the piercing end of the bag breaking component 3, completing the piercing and breaking of the bag, forming a... The suction port 211 is used for material suction. Then, the suction end of the suction component 4 extends from top to bottom into the target ton bag 2 through the suction port 211, and under negative pressure, it sucks the powder in the target ton bag 2 into the target container outside. After the automatic powder suction operation is completed, the lifting component 6 drives the bag hanging component 5 to move downward until the target ton bag 2 is placed back on the pallet 8. The bag hanging component 5 then releases the attachment to the lifting strap 22. Finally, the automatic transport device can move the pallet 8 and the target ton bag 2 that has been unpacked and picked up from the unpacking and picking area outward, and transport the new target ton bag 2 to the unpacking and picking area to perform the above unpacking and picking operation. This cycle is repeated.

The bag hanging assembly 5 includes a hook 51 and a bag hanging drive device 52. The hook 51 is connected to the bag hanging drive device 52. The bag hanging drive device 52 is used to drive the hook 51 to rotate to a first angle so that the hook 51 passes through the loading port of the lifting strap 22 of the target ton bag 2, thereby hooking the lifting strap 22 onto the concave side of the hook 51. The bag hanging assembly 5 also includes a stop bar 53, which is arranged opposite to the concave side of the hook 51. When the hook 51 rotates to the first angle, the stop bar 53 and the concave side of the hook 51 enclose a loading space. The bag hanging assembly 5 also includes a limiting mechanism 54. When the hook 51 rotates to the first angle, the movable part of the limiting mechanism 54 extends and abuts against the hook 51 to prevent the hook 51 from rotating.

The bag-breaking assembly 3 includes a bag-breaking blade 31, which extends vertically and surrounds the suction gun 42. The lower end of the blade 31 has a serrated structure 311, which punctures the top of the target ton bag 2 to form a suction port 211.

The lower end face of the blade 31 has multiple serrated structures 311, which are arranged in a semi-encircling shape along the circumference. The suction gun 42 includes an inner pipe 421 and an outer pipe 422. The upper end of the inner pipe 421 is used to connect to the target container, and the lower end of the inner pipe 421 is used to extend into the suction port 211 for powder suction operation. The outer pipe 422 covers the surface of the inner pipe 421. The inner wall of the outer pipe 422 and the outer wall of the inner pipe 421 form a flow chamber 4221.
