Description

Technical Field

[0001] This invention relates to the field of automated storage and retrieval systems (AS / RS), specifically to a complex automated storage and retrieval system based on a swappable fork stacker crane. Background Technology

[0002] Multi-variety, small-batch production has become a major trend. Improving the flexibility of current automated storage and retrieval systems (AS / RS) to adapt to this trend and increase efficiency is a key challenge. Existing AS / RS systems are equipped with multiple stacker cranes, each with different types of forks. This results in high investment costs without significantly improving inbound and outbound efficiency, and also wastes stacker crane resources.

[0003] Therefore, how to provide a complex automated storage and retrieval system based on a swappable fork stacker is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a complex automated storage and retrieval system based on a replaceable forklift stacker crane, which can be widely applied to the automated logistics distribution center warehousing field of a wide variety of products such as cigarettes, tea, food, daily necessities, and small household appliances, with small inbound and outbound flow. It solves the inbound and outbound needs of products with many specifications and small batches, with relatively low investment costs and high efficiency in inbound and outbound operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a complex automated three-dimensional warehouse system based on a replaceable fork stacker, comprising: storage racks, wherein multiple rows of storage racks are arranged at intervals, and aisle tracks are provided between adjacent rows of storage racks, and each row of storage racks is provided with multiple storage compartments.

[0006] A stacker crane, at least one stacker crane and running on the aisle track, wherein the stacker crane has a conveying mechanism and a fork locking mechanism on its lifting platform, the conveying mechanism is used to move the telescopic forks in and out, and the fork locking mechanism is located on the side of the conveying mechanism and is used to restrict the telescopic forks in the working position of the conveying mechanism.

[0007] The forklift storage room is located at one end of the storage rack and is arranged near the aisle rail. The forklift storage room has multiple fork storage positions for storing telescopic forks of different specifications. The fork storage positions are equipped with roller conveyor lines for the telescopic forks to enter and exit. The stacker crane is located near the forklift storage room and can replace the telescopic forks.

[0008] The inbound and outbound logistics line is located on the bottom or side of the forklift warehouse and close to the aisle track. The inbound and outbound logistics line is used for the entry and exit of various specifications of standardized packaged materials. Different specifications of materials are picked up and placed by stacker cranes and corresponding specifications of telescopic forks.

[0009] The control center is electrically connected to the stacker crane, conveyor mechanism, fork locking mechanism, roller conveyor line, inbound / outbound logistics line and telescopic forks to coordinate the inbound / outbound operations of materials of various specifications.

[0010] The beneficial technical effects of this invention are as follows: Storage racks are the foundation of automated warehouses. Their multi-row arrangement optimizes storage space. Unit compartments can be divided and marked according to different storage needs, facilitating the corresponding retrieval and placement of goods by stacker cranes. Stacker cranes are equipped with at least one set based on actual needs and workload. They travel on aisle rails. The stacker crane's lifting platform is equipped with a conveying mechanism and a fork locking mechanism. The conveying mechanism is used to move the telescopic forks in and out, facilitating subsequent fork replacement. The fork locking mechanism restricts the telescopic forks in the working position of the conveying mechanism, thereby ensuring the reliable and stable operation of the stacker crane. In specific implementation, telescopic forks are available in different specifications, which can be replaced by the stacker crane as needed, thereby reducing the number of stacker cranes required, reducing investment costs and space occupation. The equipped fork magazine facilitates fork replacement for the stacker crane. The inbound and outbound logistics line is connected to the rails, facilitating the stacker crane's gripping of goods in and out of the warehouse. The control center issues operation instructions, and related components can work collaboratively based on the control center to realize the automated inbound and outbound process of materials.

[0011] Preferably, the storage rack is a three-dimensional rack with multiple storage areas on both the upper and lower levels. Each storage area is divided into multiple storage compartments, and the multiple storage compartments may have the same or different sizes and shapes.

[0012] The resulting technical effect is that the three-dimensional rack can be set up with multiple storage areas in layers, and the storage units in the storage area will store materials of different specifications and shapes. Different storage units are designed in combination in the same aisle (on both sides of the aisle or on the same side), which can meet the storage needs of multiple specifications of materials and facilitate the inbound and outbound operations of materials.

[0013] Preferably, there are multiple tunnel tracks, which are connected in series by forklifts, allowing the stacker crane to travel on any of the tunnel tracks.

[0014] The resulting technical effect is that at least one stacker crane is set up according to the workload, which can reach the target aisle track at will, meeting the storage and retrieval needs of the entire automated warehouse.

[0015] Preferably, the fork storage is provided with a fork locking mechanism on the side of the roller conveyor line corresponding to the fork storage, and the fork locking mechanism is used to restrict the working position of the telescopic forks on the roller conveyor line.

[0016] The resulting technical effect is that the roller conveyor on the fork magazine assists in the entry and exit of telescopic forks, making it easier for the stacker crane to replace forks, and the fork locking mechanism on it can also lock the telescopic forks in a stable storage state in the fork magazine.

[0017] Preferably, the conveying mechanism consists of two rows of spaced roller conveyor lines. Each row of roller conveyor lines has a guide bar arranged on its top outer edge. The spaced roller conveyor lines are used to avoid obstructing the power attachment of the telescopic fork. The base of the telescopic fork is provided on both sides with a wing platform. The two roller conveyor lines move the telescopic fork by supporting the wing platforms on the corresponding sides. The sidewall of the wing platform slides against the guide bar. The fork locking mechanism is located on the outer edge of the two roller conveyor lines and is used to press against the wing platform.

[0018] The resulting technical effect is that the movement and positioning of the telescopic forks rely on the wing platforms on both sides. The telescopic forks of different specifications have the same structure and all require the setting of wing platforms to facilitate subsequent connection with the stacker crane's lifting platform.

[0019] Preferably, the inner support of the roller conveyor line is equipped with a slip-on type electric contact and communication device, and the bottom side of the telescopic fork corresponding to the wing platform is provided with a conductive slide bar. The slip-on type electric contact and communication device is connected to the conductive slide bar and used to control the operating state of the telescopic fork.

[0020] The resulting technical effect is that the telescopic forks are independent units, and the use of slip-on power supply facilitates their connection with the stacker crane and the main system. Telescopic forks of any size can be connected to the main system for control operations after being in place.

[0021] Preferably, the lifting platform is provided with a cargo frame on its side, and the cargo frame is equipped with a sensor for detecting the telescopic forks. The sensor is electrically connected to the controller of the roller conveyor line, and the roller conveyor line controls its operating status based on the detection signal of the sensor.

[0022] The resulting technical effect is that the cargo rack improves the safety of picking up and placing goods. The sensor can be an infrared sensor, which is used to detect the position of the telescopic forks and link them with the roller conveyor line on the stacker crane to facilitate the telescopic forks entering and exiting the lifting platform.

[0023] Preferably, the fork locking mechanism includes a cam lift assembly and a positioning plate. The positioning plate is horizontally disposed at the lifting end of the cam lift assembly. The positioning plate is used to press against the wing platforms on both sides of the telescopic fork and restrict the position of the telescopic fork on the roller conveyor line.

[0024] The resulting technical effect is that the fork locking mechanism is actually a lifting mechanism, which controls the horizontal movement of the positioning plate to restrict or release the position of the telescopic forks on the roller conveyor line.

[0025] Preferably, the outbound and inbound logistics lines include outbound logistics lines and inbound logistics lines arranged side by side, and the outbound and inbound logistics lines are provided in at least one layer.

[0026] The resulting technical effect is that the inbound and outbound logistics lines are actually conveyor lines, which can be set up in layers or arranged side by side. Specifically, the inbound and outbound logistics lines can be set up in multiple layers to improve the efficiency of material entry and exit.

[0027] Preferably, when goods are received into the warehouse, the control center first determines whether the telescopic forks on the stacker crane meet the operational requirements. If they do, the stacker crane travels to the corresponding inbound logistics line, retrieves the goods using its telescopic forks, and automatically stores them in the corresponding storage unit allocated by the control center.

[0028] If the telescopic forks on the stacker crane cannot meet the operational needs, the stacker crane travels to the corresponding position in the fork warehouse, unloads the onboard forks through the fork locking mechanism and conveying mechanism, and then the lifting platform is aligned with the fork storage position where the forks to be replaced are to be placed. The roller conveyor line of the corresponding fork storage position moves the telescopic forks out and into the conveying mechanism of the lifting platform. After being moved into place, the fork locking mechanism locks and positions them. Then the stacker crane automatically travels to the corresponding inbound logistics line to pick up the goods, and the subsequent storage is placed in the corresponding storage unit allocated by the control center.

[0029] When goods are out of the warehouse, the control center determines whether the telescopic forks on the stacker crane meet the operational requirements. If they do, the stacker crane carries the telescopic forks to the corresponding storage unit to retrieve the goods and automatically transports them to the corresponding outbound logistics line.

[0030] If the telescopic forks on the stacker crane cannot meet the operational needs, the stacker crane will travel to the corresponding position in the fork warehouse, unload the onboard forks, and then travel to the fork storage position of the required telescopic forks to replace them with telescopic forks of the corresponding specifications. The stacker crane will then carry the replaced telescopic forks to the corresponding storage unit to retrieve the goods and automatically transport them to the corresponding outbound logistics line.

[0031] The resulting technical effect is that, based on the collaborative control of the control center, the present invention first determines whether the onboard forks meet the operational requirements. If they do, the machine will retrieve and place goods at the target location. If they do not meet the requirements, the stacker crane needs to go to the corresponding position in the fork warehouse to replace the forks before retrieving and placing goods at the target location. The present invention has a simple structure and a high degree of automation, and can be widely applied to the field of automated unit storage of materials of various specifications and varieties in small and medium-sized enterprises.

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] See the appendix of this invention. Figures 1 to 9 According to an embodiment of the present invention, a complex automated three-dimensional warehouse system based on a replaceable fork stacker crane is provided, which includes: storage racks 1, multiple rows of storage racks 1 are arranged at intervals, and aisle rails 3 are provided on the ground between adjacent rows of storage racks 1, and each row of storage racks 1 is provided with multiple storage units 2.

[0044] Stacker crane 4, which can be a double-column aisle stacker crane or a single-column aisle stacker crane; stacker crane 4 has at least one set and runs on the aisle ground rail 3. The lifting platform 41 of stacker crane 4 is equipped with a conveying mechanism 5 and a fork locking mechanism 6. The conveying mechanism 5 is used to move the telescopic forks 7 in and out. The fork locking mechanism 6 is located on the side of the conveying mechanism 5 and is used to restrict the telescopic forks 7 in the working position of the conveying mechanism 5. The fork locking mechanism can also ensure the stable operation of the telescopic forks on the stacker crane.

[0045] Forklift storage 8 is located at one end of storage rack 1 and close to aisle rail 3. Forklift storage 8 has multiple fork storage positions. The multiple fork storage positions are used to store telescopic forks 7 of different specifications. The fork storage positions are equipped with roller conveyor lines 81 for the telescopic forks to enter and exit. Stacker crane 4 is close to forklift storage 8 and can replace telescopic forks. Different operating conditions require matching telescopic forks of the corresponding specifications (single row forks, double row forks, multi row forks, etc.), otherwise goods cannot be effectively picked up and put down.

[0046] The inbound / outbound logistics line 9 is located on the bottom or side of the forklift warehouse 8 and close to the aisle rail 3, reducing transfer time and allowing for convenient fork replacement for picking and placing goods. The inbound / outbound logistics line 9 is used for the entry and exit of various specifications of packaged materials 10. Different specifications of materials are picked up and placed by stacker cranes and corresponding telescopic forks. In specific implementation, one end of the inbound / outbound logistics line is the platform end, and the stacker crane is close to the platform end to pick up and place goods or materials on the inbound / outbound logistics line.

[0047] The control center is the central hub for operation control and an interactive platform for the coordinated operation of multiple components. The control center is electrically connected to the stacker crane 4, conveyor mechanism 5, fork locking mechanism 6, roller conveyor line 81, inbound and outbound logistics line 9, and telescopic forks 7 to coordinate the inbound and outbound operations of materials of various specifications.

[0048] In other embodiments, the storage rack 1 is a three-dimensional rack with multiple storage areas arranged in upper and lower layers. Each storage area is divided into multiple storage compartments 2. The multiple storage compartments 2 have the same or different sizes and shapes, and can have multiple depths to store longer goods. The complex combination design of the storage area is used to meet the storage needs of materials of different specifications. Materials of corresponding specifications are stored in the corresponding storage compartments. For example, the first type of material is stored in the first storage compartment, the second type of material is stored in the second storage compartment, and so on.

[0049] In other specific embodiments, there are multiple aisle rails 3, which are connected in series by fork rail components, allowing the stacker crane 4 to travel on any aisle rail 3, thus satisfying the stacker crane's full-area operation of the automated warehouse.

[0050] In some other embodiments, the fork magazine 8 is provided with a fork locking mechanism 6 on the side corresponding to the roller conveyor line 81. The fork locking mechanism 6 is used to restrict the working position of the telescopic forks 7 on the roller conveyor line 81 to ensure the stable storage of the telescopic forks in the fork magazine.

[0051] In some other specific embodiments, the conveying mechanism 5 is a roller conveyor line arranged at intervals. Each roller conveyor line has a guide bar 11 arranged on the top outer edge. The two roller conveyor lines arranged at intervals are used to avoid the power attachment of the telescopic fork 7. The base of the telescopic fork 7 is provided on both sides of the base. The two roller conveyor lines cause the telescopic fork 7 to move by supporting the corresponding side of the wing platform 71. The side wall of the wing platform 71 slides against the guide bar 11. The fork locking mechanism 6 is provided on the outer edge of the two roller conveyor lines and is used to press against the wing platform 71.

[0052] It should be noted that the conveying mechanism and fork locking mechanism on the stacker crane are actually the same as the structural layout on the fork magazine, which is intended to facilitate the transfer of telescopic forks between the lifting platform and the fork storage position.

[0053] In some other embodiments, the inner support of the roller conveyor is provided with a slipper-type contact and communication device 12, and the telescopic fork 7 is provided with a conductive slide bar 72 on the bottom side of the corresponding wing platform. The slipper-type contact and communication device 12 is connected to the conductive slide bar 72 and is used to control the operating status of the telescopic fork 7.

[0054] In other embodiments, a cargo frame 13 is provided on the side of the lifting platform 41. The cargo frame 13 is equipped with a sensor for detecting the telescopic forks. The sensor's electrical signal is connected to the controller of the roller conveyor line. The roller conveyor line controls its operating status based on the sensor's detection signal feedback.

[0055] In some other embodiments, the fork locking mechanism 6 includes a cam lift assembly 61 and a positioning plate 62. The positioning plate 62 is horizontally disposed at the lifting end of the cam lift assembly 61. The positioning plate 62 is used to press against the wing platforms on both sides of the telescopic fork and restrict the position of the telescopic fork 7 on the roller conveyor line.

[0056] In other embodiments, the inbound and outbound logistics line 9 includes outbound logistics lines and inbound logistics lines arranged side by side, with at least one layer of outbound and inbound logistics lines.

[0057] In practice, multiple inbound and outbound logistics lines can be set up to simultaneously handle inbound and outbound operations for materials of various specifications.

[0058] Specifically, when goods are received into the warehouse, the control center first determines whether the telescopic forks on the stacker crane meet the operational requirements. If they do, the stacker crane travels to the corresponding inbound logistics line, retrieves the goods using its telescopic forks, and automatically stores them in the corresponding storage unit assigned by the control center.

[0059] If the telescopic forks on the stacker crane cannot meet the operational needs, the stacker crane travels to the corresponding position in the fork warehouse, unloads the onboard forks through the fork locking mechanism and conveying mechanism, and then the lifting platform is aligned with the fork storage position where the forks to be replaced are to be placed. The roller conveyor line of the corresponding fork storage position moves the telescopic forks out and into the conveying mechanism of the lifting platform. After being moved into place, the fork locking mechanism locks and positions them. Then the stacker crane automatically travels to the corresponding inbound logistics line to pick up the goods, and the subsequent storage is placed in the corresponding storage unit allocated by the control center.

[0060] When goods are out of the warehouse, the control center determines whether the telescopic forks on the stacker crane meet the operational requirements. If they do, the stacker crane carries the telescopic forks to the corresponding storage unit to retrieve the goods and automatically transports them to the corresponding outbound logistics line.

[0061] If the telescopic forks on the stacker crane cannot meet the operational needs, the stacker crane will travel to the corresponding position in the fork warehouse, unload the onboard forks, and then travel to the fork storage position of the required telescopic forks to replace them with telescopic forks of the corresponding specifications. The stacker crane will then carry the replaced telescopic forks to the corresponding storage unit to retrieve the goods and automatically transport them to the corresponding outbound logistics line.

[0062] In the automated storage and retrieval system of this invention, after a stacker crane completes its goods storage and retrieval process, it can generally remain in its designated position to await the next processing step. If multiple stacker cranes are operating simultaneously, and remaining in their current position does not interfere with the operation of other equipment, they can remain in place to await the next processing step. If remaining in their current position does interfere with the operation of other equipment, the control center needs to assign a suitable standby position for the crane to proceed to the next processing step. This process is repeated cyclically.

[0063] The process of installing and replacing the forks of a stacker crane:

[0064] When installing forks on a stacker crane, the crane automatically travels to the location where the telescopic forks need to be installed. The lifting platform rises to the same height as the telescopic fork storage position (the conveyor mechanism on the lifting platform is at the same height as the roller conveyor line of the corresponding storage position). The telescopic forks are conveyed out and into the lifting platform. Sensors detect the forks, and the conveyor mechanism starts. Under the combined action of guide wheels or guide bars, the forks are conveyed to the required position on the stacker crane. The drive motor of the fork locking mechanism drives the cam to rotate to the low position through the transmission chain, and the positioning pressure plate presses down, achieving precise positioning and fixing of the forks. Thus, the stacker crane's preparation for storing and retrieving goods is completed.

[0065] When the stacker crane needs to remove the forks, it automatically travels to the location of the telescopic forks to be replaced, and the lifting platform rises to the same height as the telescopic fork storage position. The drive motor of the fork locking mechanism drives the cam to rotate to the high position via the transmission chain, the positioning plate rises, releasing the positioning and fixing of the telescopic forks, the conveying mechanism starts, and the forks to be replaced are conveyed from the stacker crane and sent to the empty fork placement platform.

[0066] The present invention has a simple and practical structure, saving construction and maintenance costs; it can be applied to the needs of small and medium-sized enterprises with a wide variety of materials and specifications and small outbound flow, making it convenient for small and medium-sized enterprises to automate their logistics and warehousing operations; it can be widely used in various logistics and distribution center warehouses such as chemical, tobacco, pharmaceutical, furniture, and agricultural products, with a wide range of applications.

[0067] The apparatus and methods disclosed in the embodiments are described simply because they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the method section.

[0068] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
