Description

Technical Field

[0001] This invention relates to the technical field of logistics warehousing and transportation, and in particular to an intelligent transfer and transportation device for logistics warehousing. Background Technology

[0002] With the rapid development of e-commerce and the postal express industry, modern logistics warehousing centers need to handle a large number of soft and thin goods, such as express bags, document bags, and flat parcels. These goods are generally characterized by their soft texture, easy deformation, thinness, and irregular surface (often containing wrinkles or bulges).

[0003] In automated storage and retrieval systems (AS / RS), the typical transit process for such goods includes: transporting them to the racking area via conveyor lines, transferring them through a transfer device, and then storing them on higher racks by a stacker crane or elevator; outbound shipments follow the reverse process. However, most of the transfer devices currently used are designed for rigid, regular goods (such as crates and cartons), and they exhibit significant inadequacies and inherent defects when handling soft, thin goods, mainly including:

[0004] 1. Thin document bags are lightweight and lack sufficient friction and support between individual items when stacked, making it difficult for robotic arms or stacker cranes to achieve stable and separate gripping. Especially when gripping express bags and document bags, since the force is usually applied from both sides to the middle, the goods are prone to slipping from the middle or deforming due to pressure in the middle of the goods.

[0005] 2. Traditional gripping methods can easily scratch, tear, or wrinkle the surface of soft and thin goods, threatening the safety of the contents and increasing the risk of damage.

[0006] 3. Robotic arms or stacker cranes usually need to complete the transfer of the current goods before they can perform the next grab, resulting in a long operation cycle and low overall turnover efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent transfer and conveying device for logistics warehousing, which aims to solve the problems in the prior art.

[0021] Preferably, a transfer motor is installed at the end of the specification adjustment frame, and a fourth lead screw is installed inside the motor via a bearing. The fourth lead screw is connected to the output shaft of the transfer motor.

[0022] The fourth lead screw is threaded with two fourth connecting blocks, and the negative pressure suction head is installed on the fourth connecting blocks.

[0023] Preferably, a flip motor is also installed in one of the two fourth connecting blocks on the side away from the pickup rack.

[0049] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0050] In this embodiment:

[0051] Reference Figures 1-3 The diagram shows a preferred embodiment of the present invention.

[0052] This embodiment provides an intelligent transfer and conveying device for logistics warehousing, including a transfer device 2 installed on a storage rack 1 and cooperating with a conveying device 3 for transfer and conveying.

[0053] The transfer device 2 includes a truss 21 mounted on the top of the storage rack 1. A vertical frame 22 is mounted on the truss 21 in the X direction. A support plate 24 is mounted on the vertical frame 22 in the Y direction. A guide rail 25 is provided on the support plate 24 in the Z direction and extends into or out of the storage rack 1.

[0054] Two sets of specification adjustment frames 26 and two sets of pickup frames 27 are installed on the guide rail 25. The specification adjustment frame 26 is provided with a negative pressure suction head 264 that moves along the Z direction, which is used to transfer goods between the pickup frame 27 and the storage rack 1.

[0055] The pickup rack 27 is used to stack and store multiple goods or release goods one by one, and through the combined movement of the truss 21, the upright 22 and the guide rail 25, the goods are transferred between the conveying device 3 and the storage rack 1.

[0056] The truss 21 is equipped with an X-axis motor 211 at its end. The truss 21 has a first lead screw 212 inside. The output shaft of the X-axis motor 211 is connected to the first lead screw 212. The upper end of the upright 22 is provided with a first connecting block 224 that is threadedly engaged with the first lead screw 212. Driven by the output shaft of the X-axis motor 211, the first lead screw 212 rotates in both directions, thereby driving the upright 22 with the first connecting block 224 to move in the X direction at the front edge of the transfer device 2.

[0057] Furthermore, the upright frame 22 is U-shaped, with a Y-axis motor 222 installed at its top. A second lead screw 223 is provided in the vertical part of the upright frame 22, and the second lead screw 223 is connected to the output shaft of the Y-axis motor 222. Both sides of the support plate 24 are provided with second connecting blocks 242 that are threadedly engaged with the second lead screw 223. The bottom of the upright frame 22 is also equipped with casters 221. Driven by the output shaft of the Y-axis motor 222, the two second lead screws 223 rotate synchronously under the action of the belt, thereby driving the support plate 24 with the second connecting blocks 242 to move along the Y direction on the upright frame 22.

[0058] Furthermore, the bottom of both sides of the support plate 24 is provided with guide grooves, and a number of guide wheels 244 are provided in the guide grooves. The support plate 24 is also equipped with a Z-axis motor 243 for driving the guide wheels 244. The guide rail 25 is H-shaped, and its vertical part is mounted on the guide wheels 244. It is driven by the Z-axis motor 243 to slide along the guide groove. Under the drive of the output shaft of the Z-axis motor 243, the guide wheels 244 on both sides of the support plate 24 synchronously drive the guide rail 25 mounted on it to move along the Z-axis inside and outside the storage rack 1.

[0059] Limit sensors are provided at both ends of the guide rail 25 so that the guide rail 25 can stop sliding when it travels to the two ends in the guide groove of the support plate 24. The end of the guide rail 25 is in contact with the side of the support plate 24 away from the guide wheel 244 to prevent the guide rail 25 from tilting due to the weight of the other end when it reaches the end of the support plate 24, and to facilitate the return of the guide rail 25 to its original position.

[0060] Normally, when the support plate 24 is moving in the X and Y directions, the guide rail 25 is driven by the Z-axis motor 243 to extend to the outside of the storage rack 1 to avoid affecting the movement of the support plate 24.

[0061] It is worth noting that, such as Figures 4-6As shown, an interval adjustment plate 253 is rotatably mounted on the horizontal part of the guide rail 25. An interval adjustment motor 254 is located in the middle of the interval adjustment plate 253, and a third lead screw 255 driven by the interval adjustment motor 254 is also located inside it. A helical gear meshes between the output shaft of the motor and the third lead screw 255. The third lead screw 255 has threads with opposite directions at both ends, and each is threadedly connected to a third connecting block 256. The two specification adjustment brackets 26 are respectively installed through the two third connecting blocks 256. The third connecting blocks 256 are positioned at intervals... Under the constraint of the adjusting plate 253, it can only slide inside it. Driven by the output shaft of the interval adjusting motor 254, the third lead screw 255 drives the two third connecting blocks 256 in opposite directions through the forward and reverse threads at both ends to achieve synchronous transmission, so as to adjust the distance between the two specification adjusting frames 26. According to the different widths of goods, the distance between the negative pressure suction head 264 and the picking frame 27 between the two specification adjusting frames 26 can be adjusted so that different specifications of goods can be picked up by the negative pressure suction head 264 and different specifications of goods can be lifted by the pallet 273, thus improving versatility.

[0062] The guide rail 25 has a connecting shaft 252 rotatably mounted at the center of its horizontal section. A deflection motor 251 is provided on one side of the guide rail 25. The interval adjustment plate 253 is fixed to the connecting shaft 252. The connecting shaft 252 is driven by the output shaft of the deflection motor 251. This allows the interval adjustment plate 253 to deflect around the connecting shaft 252 at a certain angle under the drive of the output shaft of the deflection motor 251, thereby adjusting the tilt of the negative pressure suction head 264 and the pallet 273 for gripping goods that are placed or conveyed at an angle on the storage rack 1 or the conveying device 3.

[0063] Meanwhile, when the guide rail 25 extends to the outside of the storage rack 1 by being driven by the Z-axis motor 243, the direction of the interval adjustment plate 253 can be reversed by the deflection motor 251, so that the negative pressure suction head 264 and the pickup rack 27 can exchange directions, so that the negative pressure suction head 264 can grab the goods located on the conveyor 3, or the pickup rack 27 can continuously place the goods on the conveyor 3.

[0064] A transfer motor 261 is installed at the end of the specification adjustment frame 26, and a fourth lead screw 262 is installed inside the motor via bearings. The fourth lead screw 262 is connected to the output shaft of the transfer motor 261. Two fourth connecting blocks 263 are threaded onto the fourth lead screw 262. The fourth connecting blocks 263 can only slide within the specification adjustment frame 26 due to its constraint. The negative pressure suction head 264 is installed on the fourth connecting blocks 263. Driven by the output shaft of the transfer motor 261, the negative pressure suction head 264 equipped with the fourth connecting blocks 263 moves on the specification adjustment frame 26 so that it can grab goods and send them to the top of the pickup rack 27 for stacking and storage. In addition, the negative pressure suction head 264 can also grab goods on the pickup rack 27 one by one and send them one by one onto the storage rack 1 or the conveyor device 3.

[0065] The two pickup racks 27 are respectively installed at the ends of the specification adjustment rack 26. The pickup rack 27 includes vertically distributed conveyor belts 272 and pickup motors 271 for driving the two sets of conveyor belts 272 to drive synchronous transmission in opposite directions. Several pallets 273 are evenly distributed on the surface of the conveyor belts 272. Under the synchronous drive of the two pickup motors 271, the two conveyor belts 272 drive the pallets 273 on opposite sides to rise and fall synchronously, so that the two adjacent pallets 273 can lift or release goods one by one, thereby forming a temporary and efficient storage mechanism to achieve the goal of transferring multiple goods at a time and effectively improve work efficiency.

[0066] Furthermore, such as Figure 8 As shown, a flip motor 265 is also installed in the two fourth connecting blocks 263 on the side away from the pickup rack 27. The negative pressure suction head 264 is connected to the output shaft of the flip motor 265 and is used to drive the negative pressure suction head 264 to rotate synchronously along the pickup rack 27. The two negative pressure suction heads 264 away from the pickup rack 27 adsorb one end of the goods and drive them to turn by the flip motor 265 so that the pickup code or identification code on the surface of the goods is placed facing upwards, which is convenient for automated sorting operation.

[0067] Furthermore, the negative pressure suction head 264 is also inclinedly installed with an air nozzle 266 away from the pickup rack 27. The air nozzle 266 is connected to the air outlet of the negative pressure pump 241. During the flipping process, it blows air to the other end of the goods to improve the flipping efficiency. At the same time, it can blow air on the surface of the goods during the flipping process to avoid the pickup code or identification code being blocked by the wrinkles on the surface of the flexible goods express bag.

[0068] In this embodiment, a power controller 23 is provided at the top of the truss 21, and a negative pressure pump 241 and a positioning probe 245 are respectively installed on the top and one side of the support plate 24. The power controller 23 contains a PLC and is electrically connected to each electrical component. It is used to program and realize real-time control of each motor so as to automate the grabbing and transfer of goods. The positioning probe 245 is a combination of an industrial barcode reader and an industrial camera (such as the Keyence CV-X / XM series vision system, which can simultaneously complete barcode recognition, pattern detection and high-precision size measurement. It is a well-known prior art and will not be described in detail here). It is used to locate the position of the goods to be grabbed or stored according to the label on the transfer device 2 (the label indicates the type and location of the goods) and can identify the goods. The positioning probe 245 can capture the barcode or pattern on the label of the goods conveyed on the conveyor device 3, identify the corresponding goods type by comparing it with the background database, and at the same time, the positioning probe 245 can capture the side image of the goods and determine the width of the goods through the PLC programming in the power controller 23 so as to drive the negative pressure suction head 264 to achieve precise positioning of the four corners of the goods. The goods in each compartment of the storage rack 1 are stacked in a uniform manner, which makes it easy to temporarily store the goods in the same compartment through the pick-up rack 27. When other sizes of goods need to be stored, it is only necessary to empty the goods on the pick-up rack 27, and the positioning probe 245 can identify the label of goods type and the width of the goods in the required transfer compartment from the side. The spacing of the two sets of specification adjustment racks 26 can be adjusted to control the spacing of the negative pressure suction head 264.

[0069] The negative pressure pump 241 provides negative pressure to the negative pressure suction head 264, enabling the negative pressure suction head 264 to adsorb the four corners of the goods under negative pressure, which is especially suitable for gripping light and thin goods.

[0070] Among them, the part of the negative pressure suction head 264 that contacts the goods is a silicone suction cup, which is less likely to damage the surface of the goods.

[0071] During use, the transfer device 2 achieves precise movement of the negative pressure suction head 264 and the pickup rack 27 in the X and Y directions through the truss 21, upright 22 and support plate 24 installed on the storage rack 1. The negative pressure suction head 264 and the pickup rack 27 are carried into the rack in the Z direction by the guide rail 25. After the negative pressure suction head 264 absorbs the goods, it flips or transfers them to the pickup rack 27. The pickup rack 27 drives the pallet 273 through two sets of reverse synchronous transmission conveyor belts 272 to realize the layer-by-layer stacking and release of goods. Then, driven by the truss 21 and upright 22, the efficient and automated transfer of goods between the conveyor device 3 and the storage rack 1 is completed.

[0072] During this process, the positioning probe 245 is used to locate the type of goods and the position of the goods to be picked up and placed, and the negative pressure pump 241 is used to provide negative pressure suction to the negative pressure suction head 264;

[0073] Driven by the deflection motor 251, the negative pressure suction head 264 and the pickup frame 27 can be deflected at a certain angle around the axis of the connecting shaft 252, which is used to grab goods that are placed or transported at an angle on the storage rack 1 or the conveyor device 3.

[0074] like Figure 7 As shown, the intelligent transfer and conveying device provided by the present invention addresses the issues of gripping stability, cargo safety, and operational efficiency of soft, thin, and easily deformable goods (express bags, document bags, and flat parcels) during the transfer process.

[0075] The 264 negative pressure suction head picks up goods by adsorption, avoiding surface mechanical damage and effectively reducing the risk of scratches, tears and wrinkles.

[0076] The pickup rack 27 utilizes the layered lifting and releasing mechanism of the pallet 273 to achieve stable stacking and reliable separation of lightweight and thin goods, solving the problem of unstable gripping caused by the light weight of goods and insufficient friction after stacking in traditional equipment.

[0077] Meanwhile, the device supports the continuous stacking and transfer of multiple items at a time, reducing the operation cycle of the transfer process. Furthermore, the gripping of multiple items is less likely to cause slippage due to the smooth surface, thus improving the efficiency and adaptability of the logistics warehousing system in handling soft and thin items.

[0078] This embodiment also includes a transfer and transportation method, which specifically includes the following steps:

[0079] First, the power controller 23 is started, putting the entire intelligent transfer and conveying device into standby mode. At this time, the positioning probe 245 begins to scan the labels on the storage rack 1, identify the type and location information of the goods, and transmit the data to the PLC in the power controller 23.

[0080] Next, based on the information fed back by the positioning probe 245, the PLC program controls the X-axis motor 211, Y-axis motor 222 and Z-axis motor 243 to work together to drive the upright 22, support plate 24 and guide rail 25 to move, so that the negative pressure suction head 264 and the pickup rack 27 accurately reach the target goods.

[0081] After the negative pressure suction head 264 reaches above the goods, the negative pressure pump 241 starts to provide negative pressure suction to the negative pressure suction head 264. The negative pressure suction head 264 uses silicone suction cups to adhere to the four corners of the goods, ensuring that even thin and light goods can be stably gripped.

[0082] Subsequently, the transfer motor 261 starts, driving the fourth lead screw 262 to rotate, which in turn drives the negative pressure suction head 264 to move on the specification adjustment frame 26, sending the goods to the top of the pickup frame 27. The conveyor belt 272 on the pickup frame 27 is driven by the pickup motor 271 to drive the reverse synchronous transmission, which drives the pallet 273 to rise and lift the goods.

[0083] If it is necessary to pick up goods that are placed or transported at an angle, the bias motor 251 is started, driving the interval adjustment plate 253 to deflect around the connecting shaft 252 at a certain angle, so that the negative pressure suction head 264 and the pickup frame 27 are tilted accordingly to adapt to the tilting state of the goods.

[0084] When goods with pickup codes or identification codes need to be placed face up, the two negative pressure suction heads 264, which are away from the pickup rack 27, are driven to pick up one end of the goods and the flip motor 265 is used to turn the goods so as to facilitate automated sorting and processing.

[0085] When goods need to be transferred from storage rack 1 to conveying device 3, truss 21, upright frame 22 and guide rail 25 move together under the drive of each motor to send the goods on the pickup rack 27 to the top of the conveying device 3. The pickup motor 271 reverses, and the conveyor belt 272 drives the pallet 273 to descend, releasing the goods one by one onto the conveying device 3.

[0086] If it is necessary to adjust the distance between the two adjustable frames 26 to accommodate goods of different widths, the interval adjustment motor 254 is started, driving the third lead screw 255 to rotate, which drives the two third connecting blocks 256 to drive in opposite synchronous transmission, thereby adjusting the distance between the two adjustable frames 26 so that the negative pressure suction head 264 and the pickup frame 27 can adapt to goods of different sizes.

[0087] Throughout the entire transfer and transportation process, the positioning probe 245 works continuously, not only for initial positioning, but also for real-time monitoring of the cargo position during cargo transfer to ensure accurate handling and placement of cargo. At the same time, the PLC in the power controller 23 adjusts the operating status of each motor in real time according to the information fed back by the positioning probe 245 and the preset program, so as to realize automated and intelligent cargo transfer and transportation.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
