Description

Technical Field

[0001] This application relates to the field of intelligent equipment for power material storage, and more specifically to a drawer-type storage cage adapted to an intelligent storage system and its control method. Background Technology

[0002] Existing warehousing systems primarily rely on pallet racks for storage. This method is impractical for applications with fragmented materials, such as power equipment warehouses and material transfer zones, where storage requires meticulous categorization and layer-by-layer matching based on different levels of classification. If a power equipment warehouse system were to directly adopt the existing pallet rack system, it would require allocating separate pallet space for each category of materials. In other words, under the current method, material retrieval would be done pallet-by-pallet. Each model of power equipment would require its own independent storage space. Different models and specifications of the same type of equipment in the power system would need to occupy several independent storage locations for accurate retrieval. This means that the existing warehousing system requires a larger storage space to effectively identify different sizes of power equipment. If different models and specifications of the same type of equipment are placed on the same pallet, when retrieving materials only from a specific sub-category pallet, a four-way trolley or similar handling equipment would first lift the entire pallet and transport it to the retrieval point for manual sorting. After manual retrieval, the remaining materials would be returned to their corresponding storage locations. This extraction method is inefficient, and when the same type of material is delivered to different extraction ports each time, it is necessary to wait for the pallet to return before extraction can be carried out. Summary of the Invention

[0003] This application addresses the shortcomings of existing technologies by providing a drawer-type storage cage and its control method adapted to intelligent warehousing systems. This application uses a drawer-type storage cage to store different subcategories and models of materials within the same major category, respectively, in different drawer layers of the cage. When retrieving materials, the actuating devices in each drawer layer of the storage cage can precisely retrieve the goods, thereby directly extracting various types of scattered materials in a single operation path. This application effectively improves material retrieval efficiency, reduces storage space, and is suitable for applications such as power material warehousing management systems that require frequent retrieval of different types of materials. The specific technical solution adopted in this application is as follows.

[0006] Optionally, the drawer-type storage cage adapted to the intelligent warehousing system as described above, wherein the drawer is made of wire mesh, or the drawer is provided with a connecting rod at least at its front end; the hook of the suspension rope is made of magnetic material; an electromagnetic coil is wound on the wire or connecting rod at the front of the drawer, the electromagnetic coil being triggered by the response signal of the RFID tag to attract the hook of the suspension rope, keeping the hook pulling the drawer upward; the electromagnetic coil also releases the attraction on the hook when the drawer reaches the top of the four-way shuttle, causing the hook to disengage from the drawer.

[0007] Optionally, as described above, a drawer-type storage cage adapted to an intelligent warehousing system is provided, wherein the suspension ropes are connected to the left and right sides of the front end of each drawer via hooks.

[0008] Optionally, the drawer-type storage cage adapted to the intelligent warehousing system as described above, wherein a power supply device is also installed in the bottom plate, and the radio frequency tag, drive system and lifting auxiliary device are electrically connected to the power supply device respectively.

[0010] Optionally, in the drawer-type storage cage adapted to the intelligent warehousing system as described above, the supporting slide rail and the auxiliary groove are respectively embedded with power supply contact lines, and the slider and lifting wheel are embedded with power supply receiving terminals. The power supply receiving terminals are electrically connected to the power supply contact lines during the movement of the drawer to maintain power supply to the electromagnetic coil at the front end of the drawer.

[0011] Meanwhile, to achieve the above objectives, this application also provides a control method for a drawer-type storage cage adapted to an intelligent warehousing system. The steps include: an RFID tag responding to the RFID signal radiated by a four-way shuttle triggering a response signal; a drive system responding to the response signal of the RFID tag on the corresponding drawer pushes the drawer forward along the support rail and simultaneously releases the suspension rope in the lifting auxiliary device; when the drawer disengages from the support rail, the lifting wheel at the rear end of the drawer is triggered to open outward, so that the lifting wheel abuts against the auxiliary groove at the front end of the support column; the lifting auxiliary device is driven to gradually release the suspension rope, so that the drawer moves downward along the auxiliary groove until it lands on the four-way shuttle waiting to be transported in front of the base plate.

[0012] Optionally, as described above, the control method for a drawer-type storage cage adapted to an intelligent warehousing system includes the following: during the downward movement of the drawer, the electromagnetic coil on the front wire or connecting rod of the drawer is maintained to maintain the attraction to the hook at the end of the suspension rope, thereby keeping the hook pulling the drawer upward.

[0016] Beneficial effects

[0017] This application provides a drawer-type storage cage adapted to an intelligent warehousing system and its control method. It utilizes RFID tags to identify electrical components within different drawers, then triggers a drive system to push out the drawer containing the corresponding type of electrical component. A lifting auxiliary device then smoothly transfers the drawer to a four-way shuttle vehicle for retrieval of the electrical component. This application allows for the individual storage of different types of electrical components using the same storage space through drawer stacking. This effectively reduces the need for separate storage spaces for different types of electrical components, simplifies the retrieval process, and improves the efficiency of storing and retrieving electrical components.

[0023] To make the objectives and technical solutions of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless defined as herein.

[0025] In this application, "inner" and "outer" refer to directions pointing inwards from the drawer-type storage cage itself, and vice versa; rather than specific limitations on the device mechanism of this application.

[0026] The terms "left" and "right" as used in this application refer to the user's left side as the left and the user's right side as the right when the user is facing the direction in which the drawer-type storage cage is being moved out, and do not constitute a specific limitation on the device mechanism of this application.

[0027] The term "connection" as used in this application can mean a direct connection between components or an indirect connection between components through other components.

[0028] The terms "up" and "down" as used in this application refer to the direction from the bottom plate to the RFID tag when the user is facing the drawer-type storage cage, which is up, and the direction from the bogie to the track system, which is down, rather than a specific limitation on the device mechanism of this application.

[0029] Figure 1 A drawer-type storage cage adapted to an intelligent warehousing system according to this application includes:

[0030] The base plate 1 has support columns 2 at its four corners, and support slide rails 3 are connected between the support columns.

[0031] Drawer 4 has a slider 5 on its outside that can slide along the support slide rail 3, and lifting auxiliary devices are provided at the front and rear ends of the sliding direction respectively.

[0032] Radio frequency tags 6 are respectively installed on the top of the support column 2 to mark the types of materials stored in each drawer 4;

[0033] The drive system, which is located at the bottom of each drawer 4, is used to respond to the response signal of the radio frequency tag 6, push the drawer 4 forward to the support slide rail 3, and then trigger the lifting auxiliary device to lower the drawer 4 to the four-way shuttle car waiting to be transported in front of the base plate 1.

[0034] The radio frequency tag 6 on the top of the drawer-type storage cage responds to the radio frequency signal radiated outward by the four-way shuttle, sends a response signal back to the four-way shuttle, and triggers the drive system in the drawer-type storage cage through the response signal. The drive system responds to the response signal and outputs a drive to the drawer 4 of the corresponding layer, causing the drawer of that layer to be pushed forward along the support slide rail 3. During the process of the drawer being pushed out, the suspension rope 22 in the lifting auxiliary device is released simultaneously.

[0035] When drawer 4 continues to move forward and is pushed out of the support slide rail 3, the lifting wheel 41 at the rear end of the drawer is triggered to open outward, so that the rim of the lifting wheel 41 abuts against the auxiliary groove 21 at the front end of the support column 2 and rolls along the auxiliary groove 21.

[0036] The lifting auxiliary device can gradually loosen the suspension rope 22 in conjunction with the downward sliding of the drawer, so that the drawer 4 moves downward along the auxiliary groove 21 until it lands on the four-way shuttle waiting to be transported in front of the base plate 1.

[0037] Therefore, this application enables the separate storage of different models of the same type of electrical equipment in different drawers of the same drawer-type storage cage, with the storage location of each model of equipment marked by RFID tags. When a specific model of electrical equipment needs to be retrieved, the four-way shuttle is driven to the corresponding drawer-type storage cage, the storage layer of the equipment is determined by the RFID tag, and then the drive system behind the drawer is triggered to move that layer of drawer forward. Finally, the suspension system smoothly lowers the equipment onto the four-way shuttle.

[0038] To ensure smooth drawer lifting, this application preferably includes the lifting auxiliary device comprising: Figure 2 Shown:

[0039] Auxiliary groove 21 is provided on the front side wall of the front support column 2;

[0040] The lifting wheel 41 is located on the rear end face of the drawer 4. It can be opened outward after the drawer 4 is pushed forward outward along the support slide rail 3, and then abut against the auxiliary groove 21 and run along the auxiliary groove 21.

[0041] The suspension rope 22 is connected between the top of the support column 2 and the front end of the drawer 4. It is used to gradually release the rope after the drawer 4 pushes forward onto the support slide rail 3, so that the drawer 4 gradually descends along the auxiliary groove 21 onto the four-way shuttle.

[0042] To ensure that the hook at the bottom of the suspension rope can maintain the drawer in a horizontal position and descend stably during the drawer lifting and lowering process, this application preferably sets the drawer 4 to be made of wire mesh, or sets a corresponding connecting rod 42 at the front end of the drawer 4, winds an electromagnetic coil on the wire or connecting rod 42 at the front of the drawer 4, and sets the hook of the suspension rope 22 to a magnetic material accordingly.

[0043] Thus, the electromagnetic coil can be triggered by the response signal of the radio frequency tag 6 to attract the hook of the suspension rope 22, keeping the hook pulling the drawer 4 upward. Through the cooperation of the hook and the rear lifting wheel, the drawer is kept in a horizontal position during the descent. The electromagnetic coil can also release the attraction force on the hook after the drawer 4 reaches the top of the four-way shuttle, causing the hook to detach from the drawer 4.

[0044] The four-way shuttle of this application can also be equipped with a rotatable gimbal structure in its body, with its cargo lifting frame mounted on the gimbal. Thus, when retrieving goods requires returning the drawer to its original storage position, the drawer can first be placed on the cargo lifting frame of the four-way shuttle, and the four-way shuttle can be driven back to the front of the drawer-type storage cage. The gimbal then rotates the drawer's installation direction, turning the connecting rod 42 to the front of the auxiliary slot of the drawer-type storage cage. Next, the drawer-type storage cage is driven to lower the hook corresponding to that drawer level, the electromagnetic coil is driven to attract the hook, and the suspension rope 22 is retracted. After the hook is suspended and attracted to the connecting rod 42, the gimbal is driven to rotate, turning the lifting wheel 41 at the rear of the drawer structure to the front of the auxiliary slot. Therefore, the drawer-type storage cage can continue to retract the suspension rope 22 to bring the lifting wheel 41 into the auxiliary groove, and lift the drawer back into the drawer-type storage cage through the suspension rope 22; or additional hooks can be further suspended to the connecting rod 42 on the rear side of the drawer and magnetically attracted to the rear end of the drawer, so that the drawer can be lifted along the auxiliary groove and returned to the support slide rail 3 through the hooks on the front and rear sides of the drawer at the same time.

[0045] To ensure smooth and synchronous movement of the left and right sides during drawer lifting, this application preferably configures the suspension ropes 22 to be connected to the left and right sides of the front end of each drawer via hooks. The magnetic field of the electromagnetic coil on the wire or connecting rod 42 at the front of the drawer 4 is maintained to retain the attraction to the hooks at the end of the suspension ropes 22, thus keeping the hooks pulling the drawer 4 upwards. A torque device can also be provided in the hooks to ensure that the hooks always rotate upwards to hook the connecting rod 42 and stably lift the drawer when it is being pulled up.

[0046] The suspension rope 22 of this application can be adjusted during the forward movement of drawer 4 according to... The length is gradually relaxed, where Δx represents the forward movement distance of drawer 4 relative to support column 2, and h represents the height of drawer 4 from the top of suspension rope 22;

[0047] The suspension rope 22 can move up and down along the auxiliary groove of the drawer 4 according to... Gradually retract upwards or release downwards. Here, x represents the total length of drawer 4, and Δh represents the descent height of drawer 4 relative to the top of the suspension rope 22.

[0048] To ensure the stable operation of the aforementioned drawer-type storage cage, this application preferably further installs a corresponding power supply device in the base plate 1. The power supply device can be directly configured as a removable and replaceable or repeatedly charged and discharged battery system, or it can be configured as a wireless charging module. Thus, the RFID tag 6, the drive system, and the lifting auxiliary device are electrically connected to the power supply device, which provides the power supply.

[0049] Specifically, the power supply device in this application may be configured to include: a receiving coil that responds to power supply from a wireless charging coil in the storage compartment floor, a rectifier structure connected to the receiving coil, and a power supply circuit that adjusts the rectified signal to achieve power supply, wherein the power supply circuit is respectively connected to the RFID tag 6, the drive system, and the lifting auxiliary device.

[0050] To achieve power supply, this application preferably embeds corresponding power supply contact lines in the support slide rail 3 and the auxiliary groove 21, and embeds corresponding power supply receiving terminals in the slider 5 and the lifting wheel 41. Thus, the power supply receiving terminals can maintain electrical connection with the power supply contact lines during the movement of the drawer 4, thereby maintaining power supply to the electromagnetic coil at the front end of the drawer 4.

[0051] Furthermore, to ensure that the hook can be attracted by the electromagnetic coil around the connecting rod 42 and hook the drawer upwards during the drawer's return to the drawer-type storage cage, this application can also provide an electrical connection terminal between the bottom of each drawer and the contact surface of the four-way shuttle's cargo lifting frame. This allows the four-way shuttle's battery to supply power to the drawer bottom plate, driving the electromagnetic coil at the drawer end to attract the hook. When the hook lifts the drawer as the suspension rope 22 retracts, the drawer can then receive power through the power supply contact line and power supply receiving terminal between the auxiliary slot 21 and the lifting wheel 41, maintaining the drive of the electromagnetic coil on the connecting rod 42 and thus keeping the hook stably lifting the drawer.

[0052] In this application, the lifting wheel 41 is preferably mounted on the elastic telescopic bracket. The bottom of the elastic telescopic bracket 43 is fixed to the rear end of the drawer, and it can be deflected inward by the abutment of the inner wall of the support slide rail 3. The support slide rail 3 can be provided with a transition surface at its front end that connects to the bottom of the auxiliary groove 21, thereby guiding the lifting wheel 41 to open the telescopic bracket at the transition surface so that the lifting wheel 41 can abut against the bottom of the auxiliary groove 21 through the guidance of the transition surface and rotate up and down along the auxiliary groove 21.

[0053] To prevent the lifting wheel 41 from slipping at the bottom of the auxiliary slot 21, this application also preferably provides anti-slip structures such as micro suction cups and nano adhesive strips on the surface of the lifting wheel 41 to provide sufficient friction to prevent the drawer from slipping and tipping over during lifting or lowering.

[0054] The above are merely embodiments of this application, and their descriptions are quite specific and detailed, but they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
