Description

Technical Field

[0001] The present invention relates to the field of logistics technology, and in particular to an intelligent warehousing system and a method of using the same. Background Art

[0002] Warehouse shelves are a type of equipment used to store goods. In order to accommodate more goods, modern warehouses are usually equipped with tall shelves. A shelf is vertically equipped with multiple layers of partitions for placing goods. Because the shelves are relatively tall, they need to be equipped with large lifting equipment. With the help of large lifting equipment, goods can be placed on the upper floors of the shelves. When picking up goods, large lifting equipment is also needed to take down the goods placed on the upper floors of the shelves. This makes it more troublesome to store and retrieve goods, and the need to be equipped with large lifting equipment greatly increases the cost. In addition, the distance between the upper and lower layers of traditional shelves is large, and the space utilization rate is low.

[0003] For example: Chinese patent publication number CN105730955A, the invention name is a three-dimensional warehouse, which discloses a three-dimensional warehouse, including: several rows of shelves arranged closely together; any row of the shelves is provided with several layers of placement boards for placing items; a stacker body that can be moved to the position of any row of the shelves; the stacker body includes a fork that can move up and down to pick up and put items on any layer of the placement board, the stacker body also includes a column that can be slidably connected to the fork for the vertical movement of the fork, and the stacker body also includes a ground rail that can be slidably connected to the bottom of the column for the horizontal movement of the column. In this invention, since the shelves are relatively tall, large-scale lifting equipment is required. With the help of large-scale lifting equipment, the goods placed on the high-level shelves can be placed. When picking up the goods, large-scale lifting equipment is also required to take down the goods placed on the high-level shelves, which makes the storage and access of goods more troublesome, and the cost is greatly increased due to the need to be equipped with large-scale lifting equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in existing warehouses, due to the relatively tall shelves, large-scale lifting equipment is needed. With the help of large-scale lifting equipment, goods can be placed on the upper floors of the shelves. When picking up goods, large-scale lifting equipment is also needed to take down the goods placed on the upper floors of the shelves, which makes the storage and retrieval of goods more troublesome and the space utilization rate is low. An intelligent warehousing system is provided to effectively solve the above problems.

[0005] The object of the present invention is achieved through the following technical solution: an intelligent storage system, characterized in that:

[0006] Storage boxes for storing goods;

[0007] The shelf assembly is composed of a plurality of shelf units that can stack the storage boxes vertically, and each shelf unit is provided with an inlet and outlet at the bottom for the storage boxes to pass through;

[0008] The stopper mechanism is arranged at the entrance and exit of the bottom of the shelf unit, and is used to hold the stored storage box when the storage box is stored in, and to hold the storage box above the storage box when the storage box is taken out;

[0009] The mobile transport vehicle is provided with a lifting pallet which can be moved vertically and is used for storing storage boxes one by one from the bottom of the shelf unit into the shelf unit or taking out the storage boxes one by one from the bottom of the shelf unit.

[0010] In the present invention, the shelf assembly adopts a modular design and is composed of a number of shelf units combined in a rectangular array. The number of shelf units can be determined according to the size of the warehouse. The storage boxes are placed in the shelf unit in a vertical stack, with the upper and lower storage boxes close to each other, which improves the space utilization in the vertical direction and enables more storage boxes to be stored in one shelf unit. In the present invention, the storage boxes enter and exit from the bottom of the shelf unit, which greatly reduces the height that the storage boxes need to rise when they are stored and retrieved. The storage boxes can be sent into the shelf unit or taken out by moving the lifting pallet on the transport vehicle, which avoids the problem of traditional warehouses requiring large lifting equipment to put goods into high-rise containers, effectively improving the convenience of storing and retrieving goods, and also reducing the cost of the warehouse. When storing goods, the mobile transport vehicle equipped with storage boxes drives to the bottom of the designated shelf unit, and uses the lifting pallet to send the storage boxes into the shelf unit assembly through the entrance and exit. The stop mechanism set at the bottom of the shelf unit can hold the storage box just stored. After the storage box is held, the lifting pallet can be lowered, and the mobile transport vehicle can also leave and carry the next storage box. When picking up goods, the mobile vehicle drives to the bottom of the shelf unit, and the lifting pallet holds the storage box at the bottom and lifts it up for a distance, and then descends. During the descent process, the stop mechanism automatically holds the storage box above the storage box so that the storage box at the bottom can be taken out. The taken out storage box can be transported to the side or stored in other shelf units according to the steps when storing goods, and then the above steps are repeated to take out all the storage boxes below the required storage box. The storage box position is synchronized to the server until the required storage box is taken, and then it is transported to the designated location. In the present invention, the mobile transport vehicle is wirelessly connected to the control server, and the movement of the mobile transport vehicle can be controlled manually or automatically by tracking guidance in conjunction with a guidance device (such as a magnetic block, a QR code) set on the ground and a control server.

[0011] Preferably, the blocking mechanism comprises a flap rotatably connected to the edge of the inlet and outlet and capable of flipping upward, the flap cantilevering toward the center of the inlet and outlet; a notch corresponding to the flap is provided at the upper or lower end of the storage box; the area of ​​the lifting support plate is greater than or equal to the bottom area of ​​the storage box, and a lifting support plate capable of vertical movement is provided on the lifting support plate. The flap is automatically flipped to a horizontal state under the action of gravity in a natural state. When storing goods, the lifting pallet lifts the storage box upwards and stops when it rises to the bottom of the flap. Then the lifting pallet continues to lift the storage box upwards. During the upward lifting process, the storage box will contact the flap, and the flap will flip upward under the push of the storage box. When the storage box rises to a certain height, the flap is separated from the storage box and flipped to a horizontal state under the action of gravity. At this time, the lifting pallet stops rising and starts to descend to the initial state. During the descent, the storage box will be supported by the flap, and the area of ​​the lifting flap is smaller than the area of ​​the bottom of the storage box. The lifting flap will not contact the flap when passing through the entrance and exit, and can pass through the entrance and exit smoothly. When taking out the storage box at the bottom, the mobile transport trolley first drives to the bottom of the shelf unit, and then lifts the lifting pallet. When the lifting pallet passes through the entrance and exit, the flap will contact the lifting pallet and flip up under the push of the lifting pallet. After the flap flips to a certain angle, the front end of the flap is just flush with the side of the storage box. At this time, the flap cannot hold the storage box, and the storage box falls onto the lifting pallet. Then the lifting pallet descends to the initial position. During the descent, the front end of the flap slides close to the side of the storage box. Due to the gravity, the flap has a tendency to flip downward. When the front end of the flap slides to the notch position, the flap will flip down and get stuck in the notch, thereby holding the storage box above the bottom storage box, and the storage box at the bottom can be taken out through the entrance and exit. The blocking mechanism has a simple and ingenious structure, is easy to manufacture, and has a purely mechanical structure with low manufacturing cost.

[0012] Preferably, the lower end of the flap is sloped.

[0013] Preferably, the blocking mechanism includes a slide groove arranged at the edge of the inlet and outlet, the opening direction of the slide groove is toward the center of the inlet and outlet, a movable card block is slidably connected in the slide groove, one end of the movable card block extends out of the slide groove, a spring is arranged between the other end of the movable card block and the end of the slide groove, and the movable card block extends to the bottom of the end outside the slide groove in a slope shape; a notch corresponding to the movable card block is arranged at the upper end of the storage box; the area of ​​the lifting support plate is greater than or equal to the bottom area of ​​the storage box, and a lifting support plate that can be moved vertically is arranged on the lifting support plate. When storing goods, the lifting pallet lifts the storage box upwards and stops when it rises to the bottom of the moving card block. The lifting pallet then continues to lift the storage box upwards. During the upward lifting process, the storage box will contact the lower end surface of the moving card block, and the moving card block will move away from the storage box under the push of the storage box. When the moving card block moves to the front end flush with the side of the storage box, the storage box can pass through the entrance and exit. When the storage box rises to the point where the moving card block is disengaged, the moving card block moves to the initial position under the action of the spring. At this time, the lifting pallet stops rising and begins to descend to the initial state. During the descent, the storage box will be supported by the moving card block, and the area of ​​the lifting pallet is smaller than the area of ​​the bottom of the storage box. The lifting pallet will not contact the moving card block when passing through the entrance and exit and can pass through the entrance and exit smoothly. When taking out the storage box at the bottom, the mobile transport trolley first drives to the bottom of the shelf unit and then raises the lifting pallet. When the lifting pallet passes through the entrance and exit, the moving card block will contact the lifting pallet and move in the direction away from the storage box under the push of the lifting pallet. When the moving card block moves to the front end flush with the side of the storage box, the storage box can pass through the entrance and exit. At this time, the moving card block can no longer support the storage box, and the storage box falls onto the lifting pallet. Then the lifting pallet descends to its initial position. During the descent, the front end of the moving card block slides close to the side of the storage box. When the front end of the moving card block slides to the notch position at the upper end of the storage box, the moving card block will be stuck in the notch under the action of the spring, thereby supporting the upper storage box, and the storage box at the bottom can be taken out through the entrance and exit.

[0014] Preferably, the mobile transport vehicle comprises a mobile chassis, a first lifting device for driving the lifting pallet to move vertically is arranged on the mobile chassis, and a second lifting device for driving the lifting pallet to move vertically is arranged on the lifting pallet. The first lifting device and the second lifting device can adopt any one of a hydraulic cylinder, a pneumatic cylinder or an electric push rod.

[0015] Preferably, the mobile transport vehicle is provided with a docking device, and the lifting platform is provided with a conveyor belt. The two mobile transport vehicles can be docked through the docking device, and after docking, the storage box on one mobile transport vehicle can be transported to the other mobile transport vehicle through the conveyor belt provided on the lifting platform, so as to realize the transfer of goods between the two vehicles.

[0016] Preferably, the docking device includes an electromagnet and a proximity sensor arranged on the side of the lifting support plate, and the proximity sensor and the electromagnet are electrically connected to a control device arranged in the mobile chassis. The proximity sensor and the electromagnet are connected to a control system arranged in the mobile chassis. When docking, the proximity sensor can detect the distance between the two vehicles in real time. When the two vehicles approach the set docking distance, the electromagnet on the vehicle is turned on and attracts the electromagnet of the opposite vehicle, thereby completing the docking. When canceling the docking, the electromagnet is turned off and the two vehicles can be separated.

[0017] Preferably, an information storage device is provided at the bottom of the storage box, and an information acquisition device capable of reading the information storage device is provided at the upper end of the lifting plate. The information storage device is a QR code, and the information acquisition device is a code scanning device. The QR code records the corresponding weight, cargo and other information of the storage box. The code scanning device can scan the QR code at the bottom of the storage box to obtain specific information of the storage box.

[0018] A method for using an intelligent warehousing system includes the following specific steps:

[0019] 1) Construction: According to the space area and volume, the shelf units are constructed into a shelf assembly in the form of a matrix, and a shelf channel for mobile transport vehicles is set under the shelf assembly;

[0020] 2) Establish a database: divide the shelf aisle into several target areas, each of which is located directly below the shelf unit. Encode the address and space height of each target area, and establish a corresponding address database to the control server; mark each storage box, and set a corresponding information storage device at the bottom of the storage box, and establish data to the control server;

[0021] 3) Loading: Place the storage box on the mobile transport vehicle, read the information storage device at the bottom of the storage box through the information acquisition device on the mobile transport vehicle, transmit the scanned data to the cloud server, and establish database information; the mobile transport vehicle moves to the target area below the relative shelf unit, and stores the storage box in the shelf unit from the entrance and exit below the shelf unit, and uploads the information obtained from the storage box and the address code information of the target area to the cloud server, and establishes database information;

[0022] 4) Picking up goods: The mobile truck moves to the target area under the corresponding shelf unit, takes out the storage boxes below the required storage boxes above the mobile truck one by one, and directly transports the taken out storage boxes one by one to other shelf units that are not full, or hands them over to other mobile trucks, which then put the storage boxes into other shelf units that are not full, until the required storage boxes are taken out and transported to the designated location, and the information is transmitted to the control server in real time, and the database is synchronized.

[0023] The beneficial effects of the present invention are as follows: in the present invention, the storage box enters and exits from the bottom of the shelf unit, which greatly reduces the height that the storage box needs to rise when storing and accessing. The storage box can be sent into the shelf unit or taken out by moving the lifting pallet on the transport vehicle, avoiding the problem of needing to rely on large lifting equipment to put goods into high-rise containers in traditional warehouses, effectively improving the convenience of storing and accessing goods, and also reducing warehouse costs.

[0036] The mobile transport vehicle 3 includes a mobile chassis 10, a first lifting device 11, a lifting pallet 12, a second lifting device, and a lifting pallet 13. The mobile chassis 10 is a prior art. The specific structure of the mobile chassis 10 can be found in the invention patent with application number CN201711136340.7, which is named as an AGV autonomous tracking intelligent vehicle for an unmanned warehouse. The first lifting device 11 is arranged on the mobile chassis 10. The first lifting device 11 is arranged vertically.

During docking, the proximity sensor 17 can detect the distance between the two vehicles in real time. When the two vehicles approach the set docking distance, the electromagnet 18 on the vehicle is turned on and attracts the electromagnet 18 of the opposite vehicle, thereby completing the docking. When the docking is canceled, the electromagnet 18 is turned off and the two vehicles can be separated.

[0037] The storage box 2 is used to place goods. The storage box 2 is placed in the shelf unit 1 in a vertical stacking manner, with the upper and lower storage boxes 2 close to each other. The upper end of the storage box 2 is provided with a notch 19 corresponding to the flap 8. The lower end of the storage box 2 is provided with a groove 20. The area of ​​the groove 20 is the same as that of the lifting pallet 13. An information storage device is provided at the bottom of the groove 20, and the information storage device is a QR code 21. The QR code 21 corresponds to the weight, type of goods and other information of each storage box. In actual use, a magnetic stripe or other induction method can also be used to record and read the information of the storage box, store the information of the storage box in the magnetic stripe, attach the magnetic stripe to the bottom of the groove of the storage box, and set a magnetic stripe reader corresponding to the magnetic stripe at the upper end of the lifting pallet 13, and read the information of the magnetic stripe through the magnetic stripe reader.

[0038] The method of using the intelligent warehousing system includes the following specific steps:

[0039] 1) Construction: According to the space area and volume, the shelf units are constructed into a shelf assembly in the form of a matrix, and a shelf channel for mobile transport vehicles is set under the shelf assembly;

[0040] 2) Establish a database: Divide the shelf aisle into several target areas, each of which is located directly below the shelf unit. Encode the address and space height of each target area, and establish a corresponding address database to the control server; mark each storage box, and affix the corresponding QR code to the bottom of the storage box, and establish data to the control server;

[0041] 3) Loading: Place the storage box on the mobile truck, scan the QR code on the bottom of the storage box through the code scanning device on the mobile truck, transmit the scanned data to the cloud server, and establish database information; the mobile truck moves to the target area below the shelf unit, and stores the storage box in the shelf unit from the entrance and exit below the shelf unit, and uploads the QR code information obtained by scanning the storage box and the address code information of the target area to the cloud server, and establishes database information;

[0042] 4) Picking up goods: The mobile truck moves to the target area under the corresponding shelf unit, takes out the storage boxes under the required storage boxes one by one, and directly puts them into other shelf units that are not yet full, or hands over the taken out storage boxes one by one to other mobile trucks, which then put the storage boxes into other shelf units that are not yet full, until the required storage boxes are taken out and transported to the designated location, and the information is transmitted to the control server in real time, and the database is synchronized.

[0043] The specific process of storing and retrieving the storage box is as follows: when storing goods, the lifting pallet lifts the storage box upward, and stops when the lifting pallet rises to the bottom of the moving card block. The storage box is then continued to be lifted upward by the lifting pallet. During the upward lifting process, the storage box will contact the lower end surface of the moving card block, and the moving card block will move away from the storage box under the push of the storage box. When the moving card block moves to the front end flush with the side of the storage box, the storage box can pass through the entrance and exit. When the storage box rises to the point where the moving card block is disengaged, the moving card block moves to the initial position under the action of the spring. At this time, the lifting pallet stops rising and begins to descend to the initial state. During the descent, the storage box will be supported by the moving card block, and the area of ​​the lifting pallet is smaller than the area of ​​the bottom of the storage box. The lifting pallet will not contact the moving card block when passing through the entrance and exit, and can pass through the entrance and exit smoothly. When taking out the storage box at the bottom, the mobile transport trolley first drives to the bottom of the shelf unit and then raises the lifting pallet. When the lifting pallet passes through the entrance and exit, the moving card block will contact the lifting pallet and move in the direction away from the storage box under the push of the lifting pallet. When the moving card block moves to the front end flush with the side of the storage box, the storage box can pass through the entrance and exit. At this time, the moving card block can no longer support the storage box, and the storage box falls onto the lifting pallet. Then the lifting pallet descends to its initial position. During the descent, the front end of the moving card block slides close to the side of the storage box. When the front end of the moving card block slides to the notch position at the upper end of the storage box, the moving card block will be stuck in the notch under the action of the spring, thereby supporting the upper storage box, and the storage box at the bottom can be taken out through the entrance and exit.

[0044] In the present invention, the shelf assembly adopts a modular design and is composed of a number of shelf units combined in a rectangular array. The number of shelf units can be determined according to the size of the warehouse. The storage boxes are placed in the shelf unit in a vertical stacking manner, and the upper and lower storage boxes are close to each other, which improves the space utilization in the vertical direction and enables more storage boxes to be stored in one shelf unit. In the present invention, the storage boxes enter and exit from the bottom of the shelf unit, which greatly reduces the height that the storage boxes need to rise when they are stored and retrieved. The storage boxes can be sent into the shelf unit or taken out by moving the lifting pallet on the transport vehicle, which avoids the problem of traditional warehouses requiring large lifting equipment to put goods into high-rise containers, effectively improving the convenience of goods storage and retrieval, and also reducing the cost of the warehouse. When storing goods, the mobile transport vehicle equipped with storage boxes drives to the bottom of the designated shelf unit, and uses the lifting pallet to send the storage boxes into the shelf unit through the entrance and exit. The stop mechanism set at the bottom of the shelf unit can hold the storage box just stored. After the storage box is held, the lifting pallet can be lowered, and the mobile transport vehicle can also leave and carry the next storage box. When picking up goods, the mobile vehicle drives to the bottom of the shelf unit, and the lifting pallet holds the storage box at the bottom and lifts it up for a distance, and then descends. During the descent process, the stop mechanism automatically holds the storage box above the storage box so that the storage box at the bottom can be taken out. The taken out storage box can be transported to the side or stored in other shelf units according to the steps when storing goods, and then the above steps are repeated to take out all the storage boxes below the required storage box until the required storage box is taken out and then transported to the designated location. In the present invention, the mobile transport vehicle is wirelessly connected to the control server, and the movement of the mobile transport vehicle can be controlled manually or automatically by tracking guidance in conjunction with a guidance device (such as a magnetic block, a QR code) set on the ground and a control server.

[0045] Embodiment 2:

[0046] like Figure 6 As shown, the difference between Example 2 and Example 1 is that in Example 2, the notch 19 is arranged at the lower end of the storage box 2 and at a position corresponding to the flap 8, and the rest of the structure is the same as that of Example 1.

[0047] Embodiment 3:

[0048] like Figure 6 As shown, Figure 7-8As shown, the difference between Example 3 and Example 1 is that: in Example 3, the blocking mechanism includes a slide groove 23 arranged at the edge of the inlet and outlet, the opening direction of the slide groove 23 is toward the center of the inlet and outlet, and a moving block 22 is slidably connected in the slide groove 23, one end of the moving block 22 extends to the outside of the slide groove 23, and a spring 24 is arranged between the other end of the moving block 22 and the end of the slide groove 23, and the moving block 22 extends to the bottom of the end outside the slide groove 23 in a slope shape, and the rest of the structure is the same as that of Example 1. When storing goods, the lifting pallet lifts the storage box upwards and stops when it rises to the bottom of the moving card block. The lifting pallet then continues to lift the storage box upwards. During the upward lifting process, the storage box will contact the lower end surface of the moving card block, and the moving card block will move away from the storage box under the push of the storage box. When the moving card block moves to the front end flush with the side of the storage box, the storage box can pass through the entrance and exit. When the storage box rises to the point where the moving card block is disengaged, the moving card block moves to the initial position under the action of the spring. At this time, the lifting pallet stops rising and begins to descend to the initial state. During the descent, the storage box will be supported by the moving card block, and the area of ​​the lifting pallet is smaller than the area of ​​the bottom of the storage box. The lifting pallet will not contact the moving card block when passing through the entrance and exit and can pass through the entrance and exit smoothly. When taking out the storage box at the bottom, the mobile transport trolley first drives to the bottom of the shelf unit and then raises the lifting pallet. When the lifting pallet passes through the entrance and exit, the moving card block will contact the lifting pallet and move in the direction away from the storage box under the push of the lifting pallet. When the moving card block moves to the front end flush with the side of the storage box, the storage box can pass through the entrance and exit. At this time, the moving card block can no longer support the storage box, and the storage box falls onto the lifting pallet. Then the lifting pallet descends to its initial position. During the descent, the front end of the moving card block slides close to the side of the storage box. When the front end of the moving card block slides to the notch position at the upper end of the storage box, the moving card block will be stuck in the notch under the action of the spring, thereby supporting the upper storage box, and the storage box at the bottom can be taken out through the entrance and exit.
