Description

Technical Field

[0001] The present invention relates to logistics equipment, and particularly to a turnover device used in cooperation with a flexible intermediate bulk container and a logistics method implemented thereby. Background Art

[0002] A pallet is a device for horizontally placing goods used for containerization, stacking, handling, and transportation. A flexible intermediate bulk container, also known as a ton bag or a bulk bag, is a flexible packaging container, which is mostly applied to industries in the upper reaches of the industrial chain, such as the packaging and transportation of bulk commodities such as mineral products, chemical products, grains, and cement. It is a packaging with low cost and large capacity, suitable for quick loading and unloading, and has been widely used for nearly two decades.

[0003] Currently, with the increase in the costs of labor and land factors, the upgrading of warehousing logistics in many enterprises has accelerated, and the demand for the construction of automated stereoscopic warehouses has exploded. Some large enterprises have established an intelligent logistics system covering the entire process of packaging, palletizing, film covering, warehousing, storage, loading and unloading, etc. The whole process uses pallets as storage units and metering unit media for integrated through-transportation to improve the overall supply chain management efficiency, reduce logistics costs, and enhance product competitiveness; the pallets of the vast majority of enterprises are circulated within the enterprises, while outside the enterprises, due to factors such as non-uniform pallet specifications, difficult recycling, and reduction of loading space by pallet transportation, pallets cannot be circulated and used in the logistics operation chain.

[0004] In order to solve the problems in the circulation link, there are currently two solutions:

[0005] 1. Using inexpensive disposable pallets in the logistics chain, replacing the in-plant pallets with out-plant pallets before the products are shipped out for pallet turnover operations; however, this solution requires additional purchase of out-plant pallets, increasing the pallet purchase cost; and disposable pallets will cause waste in the logistics chain, which is contrary to the concept of circular economy advocated by the country; the management of multiple pallets also brings management efficiency problems.

[0006] 2. Removing the pallet by using a turnover device and equipping a pusher on the forklift to load the pallet-free goods into the logistics vehicle; this solution requires additional purchase of a forklift pusher, increasing the loading and unloading cost; the pallet-free goods cannot perform mechanized forklift operations in the next logistics link, increasing the labor and loading and unloading costs downstream. Summary of the Invention

[0007] The present invention provides a flipping device for use in conjunction with a flexible intermediate bulk container (FIBC), which can replace a pallet with an FIBC, reduce the loading and unloading costs in the logistics process of downstream enterprises, and has a simple structure. The cooperation between the mechanical gripper and the silo realizes automatic flipping, which is convenient to operate. In addition, the present invention also provides a logistics method implemented by using this flipping device. In this method, the pallet is replaced with an FIBC by using the FIBC flipping device, which is convenient for handling by a forklift, and the FIBC is relatively easy to recycle and reuse, thereby reducing the logistics costs of goods in the industrial chain.

[0008] To solve the above technical problems, the present invention discloses a flipping device for use in conjunction with an FIBC, comprising: a frame body and a silo; an installation area is provided on one side of the frame body, and the silo is rotatably arranged on the frame body and can be driven by a rotation drive assembly to realize flipping; the silo includes a connecting side plate, a slip-limiting side plate, a fixed support plate and a movable support plate; the connecting side plate is rotatably connected to the frame body, the fixed support plate and the movable support plate are respectively arranged at both ends of the connecting side plate, the fixed support plate is fixedly connected to the connecting side plate, the movable support plate can slide relative to the connecting side plate so as to change the distance between it and the fixed support plate, and the slip-limiting side plate is fixedly arranged on one side of the connecting side plate, thereby forming a receiving area for placing goods; in addition, a mechanical gripper assembly for locking the sling loop of the FIBC is provided outside the fixed support plate.

[0009] In the technical solution of the present invention, the opening of the installation area and the receiving area can respectively accommodate and place the silo and the FIBC goods, reducing the occupation of the overall space; the mechanical gripper assembly can hoist and transport the sling loop of the FIBC after flipping, eliminating the traditional method of adding a pallet at the bottom of the goods for transportation and loading and unloading. By loading and transporting the FIBC and the goods together, the labor costs and loading and unloading costs in the downstream logistics process can be reduced. The overall structure is simple, and it is convenient for forklift handling and loading and unloading; the fixed support plate and the movable support plate respectively play a role in supporting and compressing the FIBC goods, preventing the FIBC goods from scattering during the flipping process.

[0010] As an optimization, the mechanical gripper assembly includes: a connecting rod and a locking hook; the connecting rod is fixedly arranged in a "cross" shape on the fixed support plate, and a locking hook is respectively arranged at each of the four end portions of the connecting rod.

[0011] In the technical solution of the present invention, the connecting rod and the locking hook correspond to the sling loop of the FIBC when the FIBC goods are loaded onto the silo. The locking hook locks the sling loop to realize the hanging of the FIBC goods after flipping. The structure of the mechanical gripper assembly is reasonably arranged, and the cooperation with the forklift and the FIBC effectively reduces the loading and unloading costs.

[0012] As an optimization, the locking hook includes: a fixed seat, a rotating locking hook, and a fixed locking hook; the fixed seat is fixedly arranged on the connecting rod, a cavity is formed on one side of the fixed seat away from the connecting rod, the fixed locking hook is located in the cavity and is fixedly arranged on the inner side of the fixed seat, and the rotating locking hook is located in the cavity and is rotatably arranged on the inner side of the fixed seat by a first cylinder.

[0013] In the technical solution of the present invention, the fixed seat, the rotating locking hook, and the fixed locking hook are installed on the connecting rod. The cooperation between the rotating locking hook and the fixed locking hook locks and releases the sling of the container bag, and lifts the container bag goods after the silo is overturned to cooperate with the external forklift for loading and unloading operations.

[0014] As an optimization, the first cylinder is fixedly arranged on the connecting rod, and one end of the push rod of the first cylinder is hinged to one end of the rotating locking hook, and one end of the fixed locking hook is hinged to the rotating locking hook.

[0015] In the technical solution of the present invention, the rotation of the rotating locking hook driven by the first cylinder makes the overall structure simple. With the cooperation of the control program, automatic operation can be realized, manual operation is reduced, and the loading and unloading efficiency is improved.

[0016] As an optimization, the fixed pallet is square, and there is an opening at each of the four corner positions, and the four locking hooks are respectively arranged at the four openings.

[0017] In the technical solution of the present invention, the anti-slip side plate plays a role in preventing slipping and blocking during the overturning process of the container bag goods, and the connecting side plate plays a role in supporting during the overturning process of the container bag goods, effectively avoiding scattering during the overturning process of the container bag goods. The opening design enables the sling of the container bag to cooperate with the mechanical claw assembly to realize the locking of the two, avoiding the influence of the setting of the fixed pallet on the hanging of the container bag, and the internal structure is reasonably arranged.

[0018] As an optimization, the rotary drive assembly includes a rotary assembly and a drive element. The drive element includes a drive motor. The rotary assembly includes a drive gear and a connecting gear; the drive motor is fixedly arranged on one side of the frame body, the drive gear is arranged on the output shaft of the drive motor, one side of the connecting gear is rotatably arranged on the frame body, and the other side is fixedly connected to the connecting side plate, and the drive gear meshes with the connecting gear. The drive gear and the connecting gear form a gear reduction mechanism. In the technical solution of the present invention, the drive motor drives the drive gear and the connecting gear to realize a 180-degree overturning of the silo on the frame body. At the same time, the reduction mechanism formed by the drive gear and the connecting gear can reduce the load of the drive motor and improve the service life of the drive motor to a certain extent.

[0019] As an optimization, the movable pallet is connected to the piston rod of a fixedly arranged second cylinder. In the technical solution of the present invention, the second cylinder controls the movable pallet to rise or fall, thereby realizing the compression or release of the space in the accommodating area.

[0020] The present invention also discloses a logistics method, which is realized by the above-mentioned turnover device used in cooperation with the flexible intermediate bulk container (FIBC), specifically as follows: For the goods placed on the pallet, the FIBC is put on the goods in an upside-down manner, so that the pallet and the FIBC lifting rings are located at the same end of the goods. Then, the forklift is used to move the pallet together with the goods and the FIBC into the accommodating area of the silo and unload them onto the fixed pallet; Then, the mechanical gripper assembly is used to lock the FIBC lifting rings; The rotary drive assembly works to rotate the silo by a certain degree. After the goods are turned over with the silo, the FIBC lifting rings are hung on the mechanical gripper assembly; Next, the forklift forks are inserted into the inner side of the FIBC lifting rings, and then the mechanical gripper assembly is released so that the FIBC lifting rings are hung on the forklift forks. Then, the forklift drives away from the turnover device, transports the goods to the next designated location, unloads them, and the pallet located on the top of the goods is removed manually. In the subsequent logistics process, the forklift forks are inserted into the FIBC lugs to lift the goods to realize the transfer of the goods.

[0021] In the technical solution of the present invention, the FIBC is put on the goods in an upside-down manner and is turned over by the drive of the rotary drive assembly, so that the mechanical gripper assembly cooperates with the lifting rings to hang the FIBC goods. After turning over, the FIBC goods are forklifted and loaded and unloaded by the forklift. The turning-over method and the forklift loading and unloading method are simple, abandoning the traditional one-time pallet use method, improving the utilization rate of the goods pallet, and replacing the pallet with the FIBC through the FIBC turnover device, which is convenient for using the forklift to carry, and the FIBC is relatively easy to recycle and reuse, so that the logistics cost of the goods in the industrial chain is reduced.

[0022] As an optimization, before the rotary drive assembly drives the silo to turn over, the second cylinder drives the movable pallet to move downward to compress the space of the silo and press the goods tightly in the accommodating area; After the rotary drive assembly drives the silo to turn over, the second cylinder drives the movable pallet to move downward to release the compressed space in the silo.

[0023] In the technical solution of the present invention, the fixed pallet compacts the FIBC goods before turning over, so that the goods in the FIBC are not easily scattered when the silo turns over and remain in a tight state. After turning over, the movable pallet moves downward to release the compacted goods, so that the lifting rings are hung on the mechanical gripper assembly to facilitate the work of the forklift. The forklift loads and unloads the FIBC and the goods together, abandoning the method of manual loading and unloading in the downstream enterprise logistics link in the existing solution, replacing the pallet with the FIBC through the FIBC turnover device, which is convenient for using the forklift to carry, and the FIBC is relatively easy to recycle and reuse, so that the logistics cost of the goods in the industrial chain is reduced.

[0024] The advantages of the technical solution of the present invention over the prior art also lie in: it can effectively reduce the packaging cost of goods (transporting with pallets, since the pallets themselves need to occupy the space of the truck, which will increase the transportation cost, and theoretically the increase in freight can reach 30%-40%); it can improve the packaging safety of goods through the high strength and durability of the flexible intermediate bulk container, and avoid the risk of damage during the forklift transportation process (the traditional method uses cold stretch film for packaging, which has limited strength and low puncture resistance and is easily damaged during transportation); it can improve the logistics transportation efficiency, eliminate the use of traditional pallets in the logistics link, and carry out loading and unloading operations through the lifting lugs of the flexible intermediate bulk container and the forklift, with convenient operation and high work efficiency; in addition, it can implement the recycling plan of the flexible intermediate bulk container, and the recycling of the flexible intermediate bulk container is more convenient compared with the recycling of pallets, which is more conducive to the green promotion and low-carbon development of the supply chain.

Detailed implementation manners

[0038] The following will further describe in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention. The content not described in detail below all belongs to the common general knowledge in the art.

[0039] Refer to Figures 1 to 12 , a turnover device for use in conjunction with a flexible intermediate bulk container, comprising: a frame body 1 and a silo 2; an installation area 101 is provided on one side of the frame body 1, and the silo 2 is rotatably arranged on the frame body 1 and can be driven by a rotary drive assembly 3 to achieve turnover; the silo 2 includes a connecting side plate 202, an anti-slip side plate 203, a fixed support plate 204 and a movable support plate 205; the connecting side plate 202 is rotatably connected to the frame body 1, the fixed support plate 204 and the movable support plate 205 are respectively arranged at both ends of the connecting side plate 202, the fixed support plate 204 is fixedly connected to the connecting side plate 202, and the movable support plate 205 can slide relative to the connecting side plate 202 so as to change the distance between it and the fixed support plate 204. The anti-slip side plate 203 is fixedly arranged on one side of the connecting side plate 202, thereby forming an accommodating area 201 for placing goods; in addition, a mechanical gripper assembly 5 for locking the sling of the flexible intermediate bulk container is provided outside the fixed support plate 204.

[0040] Thus, one side of the frame body 1 is "L"-shaped, the other side is triangular, the size of the space of the accommodating area 201 is adjusted by the movable support plate 205, when the space of the accommodating area 201 is compressed, the goods in the flexible intermediate bulk container are compacted, and vice versa, the goods in the flexible intermediate bulk container are released; the opening of the installation area 101 and the accommodating area 201 can respectively accommodate and place the silo 2 and the goods in the flexible intermediate bulk container, reducing the occupation of the overall space; the mechanical gripper assembly 5 can hoist and transport the sling of the flexible intermediate bulk container after turnover, eliminating the traditional method of adding a pallet at the bottom of the goods for transportation and loading and unloading. The overall structure is simple, and the forklift handling and loading and unloading are convenient; the movable support plate 205 and the fixed support plate 204 play a role in supporting and compressing the goods in the flexible intermediate bulk container, avoiding the scattering of the goods in the flexible intermediate bulk container during the turnover process.

[0041] Refer to Figure 3 , Figure 4 and Figure 5, the mechanical gripper assembly 5 includes: a connecting rod 501 and a locking hook 502; the connecting rod 501 is fixedly arranged on the fixed support plate 204 in a "cross" shape, and the locking hooks 502 are respectively arranged at the four ends of the connecting rod 501.

[0042] Thus, the opening direction of the locking mouth of the locking hook 502 corresponds to the fixed support plate 204. When the containerized bag goods are placed in the silo 2, its lifting rings are aligned with the locking hooks 502, and the hanging and locking are achieved through the locking hooks 502. The connecting rod 501 and the locking hooks 502 are aligned with the lifting rings of the containerized bag when the containerized bag goods are loaded onto the silo 2. The lifting rings are locked by the locking hooks 502 to realize the hanging of the containerized bag goods after flipping. The structure of the mechanical gripper assembly 5 is reasonably arranged, and when used in combination with a forklift and a containerized bag, the handling cost can be effectively reduced.

[0043] Refer to Figure 7 and Figure 8 , the locking hook 502 includes: a fixed seat 512, a rotating locking hook 522, and a fixed locking hook 532; the fixed seat 512 is fixedly arranged on the connecting rod 501. A cavity 4 is formed on the side of the fixed seat 512 away from the connecting rod 501. The fixed locking hook 532 is located in the cavity 4 and is fixedly arranged on the inner side of the fixed seat 512. The rotating locking hook 522 is located in the cavity 4 and is rotatably arranged on the inner side of the fixed seat 512 through a first cylinder 801.

[0044] Thus, one end of the first cylinder 801 and the rotating locking hook 522 are connected through a connecting member 10. The first cylinder 801, the connecting member 10, and the rotating locking hook 522 form a three-link structure. The first cylinder 801 pushes the connecting member 10 outwards to drive the rotating locking hook 522 to open outwards; when the fixed seat 512, the rotating locking hook 522, and the fixed locking hook 532 are installed on the connecting rod 501, the cooperation between the rotating locking hook 522 and the fixed locking hook 532 locks and releases the lifting rings of the containerized bag, and the containerized bag goods are lifted after the silo 2 is flipped to cooperate with the external forklift handling operation.

[0045] Refer to Figure 1 and Figure 7 , the first cylinder 801 is fixedly arranged on the connecting rod 501, and one end of the push rod 811 of the first cylinder 801 is hinged to one end of the rotating locking hook 522. One end of the fixed locking hook 532 is hinged to the rotating locking hook 522; the movable support plate 205 is connected to the piston rod of the fixedly arranged second cylinder 802.

[0046] Thus, before the silo 2 is turned over, the movable pallet 205 is located above the frame 1. After the container bag goods are loaded into the silo 2, the second cylinder 802 drives the bottom plate 6 to move downward to compress the container bag goods. After the silo 2 is turned over, the movable pallet 205 is located below the frame 1. After the mechanical claw assembly 5 hooks the sling of the container bag, the movable pallet 205 moves downward through the second cylinder 802 to release the container bag goods. By driving the rotating hook 522 to rotate through the first cylinder 801, the overall structure is simple, and it can achieve automatic operation in cooperation with the control program, reducing manual operation and improving the loading and unloading efficiency.

[0047] Refer to Figures 1 to 6 , the fixed pallet 204 is square, and there is an opening 9 at each of its four corner positions. Four hooks 502 are respectively arranged at the four openings 9.

[0048] Thus, the connecting side plate 202 and the anti-slip side plate 203 are respectively vertically arranged on the fixed pallet 204, and the connecting side plate 202 and the anti-slip side plate 203 are arranged at a vertical angle; the connecting side plate 202 and the anti-slip side plate 203 play a role in supporting the container bag goods, effectively avoiding scattering during the turning process of the container bag goods. The design of the opening 9 enables the sling of the container bag to cooperate with the mechanical claw assembly 5 to achieve the hooking of the two. The opening 9 is diamond-shaped (the opening 9 can also be any shape such as circular, rectangular, etc. Any form that can achieve the cooperation between the sling and the hook is the protected content of the present invention).

[0049] Refer to Figures 9 to 12 , the rotation drive assembly 3 includes a rotation assembly and a drive element. The drive element includes a drive motor 301, and the rotation assembly includes a drive gear 302 and a connecting gear 303; the drive motor 301 is fixedly arranged on one side of the frame 1, the drive gear 302 is arranged on the output shaft of the drive motor 301, one side of the connecting gear 303 is rotatably arranged on the frame 1, and the other side is fixedly connected to the connecting side plate 202, and the drive gear 302 meshes with the connecting gear 303. The drive gear 302 and the connecting gear 303 form a gear reduction mechanism.

[0050] Thus, when the drive motor 301 works, it drives the drive gear 302 to rotate. The drive gear 302 and the drive motor 301 are respectively located on both sides of the frame 1. One side of the connecting gear 303 is rotatably arranged on the frame 1 through a bearing, and the other end is fixedly connected to the silo 2. The rotation of the drive gear 302 causes the connecting gear 303 to rotate on the frame 1, thereby synchronously driving the silo 2 to turn over.

[0051] In this embodiment, after the goods are packaged in a flexible intermediate bulk container (FIBC), they are flipped on the silo and the mechanical gripper assembly 5 hooks the FIBC, which facilitates the transportation and loading / unloading of the FIBC goods by an external forklift. The use of traditional pallets is eliminated, and replacing them with FIBCs can reduce the pallet usage cost, and at the same time reduce the labor cost and loading / unloading cost of downstream enterprises. The flipping device has a simple structure, and the cooperation between the mechanical gripper assembly 5 and the silo realizes automatic flipping, which is convenient to operate.

[0052] Refer to Figure 2 and Figure 3 , a logistics method implemented by a flipping device for use with an FIBC is as follows: For goods placed on a pallet, the FIBC is put on the goods in an upside-down manner so that the pallet and the FIBC lifting rings are at the same end of the goods. Then, the forklift is used to move the pallet together with the goods and the FIBC into the accommodation area 201 of the silo 2 and unload them onto the fixed pallet 204. Then, the mechanical gripper assembly 5 is used to lock the FIBC lifting rings. The rotation drive assembly 3 operates to rotate the silo 2 by 180 degrees. After the goods are flipped with the silo 2, the FIBC lifting rings are hooked on the mechanical gripper assembly 5. Next, the forklift forks are inserted into the inside of the FIBC lifting rings, and then the mechanical gripper assembly 5 is released so that the FIBC lifting rings are hung on the forklift forks. Then the forklift drives away from the flipping device, transports the goods to the next designated location, unloads them, and the pallet at the top of the goods is removed manually. In the subsequent logistics process, the forklift forks are inserted into the FIBC lugs to lift the goods to achieve the transfer of the goods.

[0053] Thus, the FIBC is inverted on the goods and flipped by the rotation assembly 3, so that the mechanical gripper assembly 5 cooperates with the lifting rings to hang the FIBC goods. After flipping, the FIBC goods are forked and loaded / unloaded by the forklift. The flipping method and the forking and loading / unloading method are simple, effectively reducing the loading / unloading cost.

[0054] Refer to Figure 2 and Figure 3 , before the rotation drive assembly 3 drives the silo 2 to flip, the second cylinder 802 drives the movable pallet 205 to move downward, compressing the space of the silo 2 and pressing the goods tightly in the accommodation area 201. After the rotation drive assembly 3 drives the silo 2 to flip, the second cylinder 802 drives the movable pallet 205 to move downward, releasing the compressed space in the silo 2.

[0055] Thus, the movable pallet 205 compacts the FIBC goods before flipping, so that the goods in the FIBC are not easily scattered when the silo flips and remain in a tight state. After flipping, the movable pallet 205 moves downward to release the compacted goods, so that the lifting rings are hooked on the mechanical gripper assembly to facilitate the work of the forklift.

[0056] In this embodiment, the pallet is replaced with a flexible intermediate bulk container (FIBC). Before the goods are flipped, the goods are nested upside down. After the silo is flipped, an external forklift is used to fork and remove the lifting rings of the FIBC, realizing the synchronous transportation of the FIBC and the goods. This can effectively reduce the pallet cost in the logistics link and at the same time reduce the loading and unloading cost of downstream enterprises in the logistics link. The second cylinder drives the movable pallet to compact and release the FIBC goods. The overall way of flipping the goods is simple, convenient to operate and use, and effectively reduces waste and cost in the loading, unloading and transportation processes.

[0057] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.

A logistics implementation method using the turnover device for use in conjunction with a flexible intermediate bulk container described in claim 1, characterized in that specifically as follows: For the goods placed on the pallet, the flexible intermediate bulk container is put on the goods in an upside-down manner, so that the pallet and the flexible intermediate bulk container sling are located at the same end of the goods. Then, the pallet together with the goods and the flexible intermediate bulk container are carried into the accommodation area (201) of the silo (2) by a forklift and unloaded onto the fixed pallet (204). Then, the mechanical gripper assembly (5) is used to lock the flexible intermediate bulk container sling. When the rotation drive assembly (3) operates to rotate the silo (2) by 180 degrees, after the goods are turned over with the silo (2), the flexible intermediate bulk container sling is hung on the mechanical gripper assembly (5). Next, the forklift forks are inserted into the inner side of the flexible intermediate bulk container sling, and then the mechanical gripper assembly (5) is released so that the flexible intermediate bulk container sling is hung on the forklift forks. Then the forklift drives away from the turnover device, transports the goods to the next designated location, unloads them, and the pallet located at the top of the goods is removed manually. In the subsequent logistics process, the forklift forks are inserted into the flexible intermediate bulk container lugs to lift the goods to achieve the transfer of the goods.

8. The logistics implementation method according to claim 7, characterized in that before the rotation drive assembly (3) drives the silo (2) to turn over, the second cylinder (802) drives the movable pallet (205) to move downward to compress the space of the silo (2) and press the goods tightly in the accommodation area (201). After the rotation drive assembly (3) drives the silo (2) to turn over, the second cylinder (802) drives the movable pallet (205) to move downward to release the compressed space in the silo (2).
