Abstract
Description
Technical Field
[0001] This application relates to the field of logistics and warehousing system technology, and in particular to a picking station and warehousing system. Background Technology
[0002] In the logistics and warehousing field, picking is an essential part. In related technologies, transport robots move boxes containing materials from the shelving area to the picking station, where they are sorted by humans or other robots. After sorting, transport robots then return the boxes to the shelving area. Once a transport robot picks up a box from the shelving area, it becomes bound to that box until it is returned. Because the picking process at the picking station takes a long time, queues and congestion of transport robots are common. These queues prevent robots carrying already picked boxes from leaving the picking station in time, and prevent robots carrying boxes to be picked from entering the station promptly, thus reducing the picking efficiency and creating a vicious cycle. Utility Model Content
[0003] This application aims to address one of the technical problems in related technologies to a certain extent. To this end, this application provides a picking station and warehousing system that can solve the congestion problem of transport robots at the picking station and improve work efficiency.
[0004] To achieve the above objectives, this application adopts the following technical solution: a picking station capable of handing over toy boxes to a transport robot, including a first lifting device, a second lifting device, and a toy box translation device. The first lifting device includes a first bearing component and a first lifting channel. The first lifting channel includes a first handover position and a first buffer position for accommodating the toy box. The first bearing component is capable of transporting the toy box between the first handover position and the first buffer position.
[0005] The second lifting device includes a second bearing component and a second lifting channel. The second lifting channel includes a second transfer position and a second buffer position for accommodating the material box. The second bearing component is capable of transporting the material box between the second transfer position and the second buffer position.
[0006] The hopper translation device includes a third bearing component and a hopper translation channel. The hopper translation channel is respectively connected to the first lifting channel and the second lifting channel at the first buffer position and the second buffer position. The third bearing component can transport the hopper along the hopper translation channel between the first buffer position and the second buffer position.
[0007] In this technical solution, the transport robot transports the bin to the first or second handover position of the first or second lifting device. One of the first or second lifting devices moves the bin carried on the transport robot from the first or second handover position to the first or second buffer position. The bin translation device picks up and transfers the bin from the first or second buffer position. The bin can be picked up during its movement on the bin translation device. The picked bin is then transported to the other of the first or second buffer positions via the bin translation device. The other of the first or second lifting device then transports the bin from the buffer position to the handover position and performs a bin handover with the transport robot. After picking up the bin, the transport robot leaves the picking station. By implementing the above settings, the transport robot can detach from the picking box after transporting it to the picking station. It no longer needs to wait with the box for the picking operation to complete, reducing the waiting time of the transport robot. This reduces the number of transport robots required, avoids queues and congestion at the picking station, improves the utilization or turnover rate of the transport robots, saves costs, and also improves the work efficiency of the sorting station.
[0008] Preferably, the material box translation channel is provided with a plurality of sorting positions for accommodating the material box, the plurality of sorting positions being located between the first buffer position and the second buffer position, and the plurality of sorting positions, the first buffer position and the second buffer position being able to accommodate the material box without interfering with each other.
[0009] Preferably, the picking station further includes a passageway for the transport robot to pass through, the passageway connecting the first handover position and the second handover position, the first bearing component and the second bearing component respectively handing over the material box to the transport robot at the first handover position and the second handover position.
[0010] Preferably, both the first and second bearing components include two sets of vertically paired slide rails, with a first clamping arm and a second clamping arm slidably connected within each set of slide rails. The first and second clamping arms are arranged opposite each other in the horizontal direction and can slide synchronously within the slide rails.
[0011] Preferably, the first clamping arm and the second clamping arm can form a first connection state and a second connection state relative to the slide rail and slide within the slide rail. When the first clamping arm and the second clamping arm form a first connection state relative to the slide rail, the first clamping arm and the second clamping arm can move relative to the material box along both sides of the material box. When the first clamping arm and the second clamping arm form a second connection state relative to the slide rail, the first clamping arm and the second clamping arm can support the material box and drive the material box to move along the slide rail.
[0012] Preferably, both the first clamping arm and the second clamping arm include a support arm arranged in a horizontal direction. Both ends of the support arm are hinged to a first connecting rod. Each set of slide rails includes a first slide rail and a second slide rail arranged opposite to each other. A slider is provided in both the first slide rail and the second slide rail. The first connecting rod is hinged to the slider. The slider is also slidably connected to a second connecting rod. The second connecting rod is also hinged to either the first connecting rod or the support arm.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this application and should not be construed as limiting it.

The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.
[0027] In related technologies, transport robots are required to constantly carry boxes into the picking station for manual or other picking robots to pick, and then transport the boxes to designated locations after picking. This easily leads to queuing and congestion of transport robots at the picking station, resulting in low utilization or turnover rates, wasted transport resources, and reduced efficiency of picking operations. To address these issues, the inventors of this application devised a method to convert the ground queuing of transport robots into spatial queuing at the picking station. Furthermore, the transport robot's task is divided into two independent stages: first, the transport robot picks up the boxes to be picked at a designated location and transports them to the picking station for picking; second, the transport robot picks up the already picked boxes at the picking station and transports them to designated locations. The transport robot does not need to wait for the boxes it brought into the picking station to be picked; it only needs to pick up another already picked box at the picking station to begin the next transport task. This reduces the waiting time of the transport robots, improves their utilization and turnover rates, and consequently reduces the number of transport robots required, thereby increasing work efficiency while reducing costs.
[0028] like Figure 1-2As shown, a picking station capable of exchanging bins 400 with a transport robot includes a first lifting device 100, a second lifting device 200, and a bin translation device 300. The first lifting device 100 includes a first carrying component 120 and a first lifting channel. The first lifting channel includes a first transfer position 111 and a first buffer position 112 for accommodating the bins 400. The first carrying component 120 is capable of transporting the bins 400 between the first transfer position 111 and the first buffer position 112.
[0029] The second lifting device 200 includes a second bearing component 220 and a second lifting channel. The second lifting channel includes a second junction position 211 and a second buffer position 212 for accommodating the material box 400. The second bearing component 220 is capable of transporting the material box 400 between the second junction position 211 and the second buffer position 212.
[0030] The hopper translation device 300 includes a third bearing component 310 and a hopper translation channel. The hopper translation channel is respectively connected to the first lifting channel and the second lifting channel at the first buffer position 112 and the second buffer position 212. The third bearing component 310 can transport the hopper 400 along the hopper translation channel between the first buffer position 112 and the second buffer position 212.
[0031] In this embodiment, both the first lifting device 100 and the second lifting device 200 can be used for lifting or lowering the material box 400. For ease of explanation, in the following embodiments, the first lifting device 100 is used for lifting the material box 400, and the second lifting device 200 is used for lowering the material box 400. Furthermore, there is a height difference between the first transfer position 111, the second transfer position 211, the first buffer position 112, and the second buffer position 212. However, the height relationship between them can be determined according to specific usage requirements. For example, if the transport robot travels on the ground and the picking station is located above the ground, then the first buffer position 112 and the second buffer position 212 are higher than the first transfer position 111 and the second transfer position 211. In special cases, such as when the warehousing system has a multi-layered spatial structure, the picking station is located on the bottom layer, and the transport robot can travel on the upper layer, then the first transfer position 111 and the second transfer position 211 are higher than the first buffer position 112 and the second buffer position 212. For ease of explanation, in the following embodiments, the transport robot travels on the ground, the picking station is set above the ground, and the first buffer position 112 and the second buffer position 212 are higher than the first handover position 111 and the second handover position 211.
[0032] In this embodiment, the transport robot transports the box 400 to the first handover position 111 of the first lifting device 100. The first bearing component 120 of the first lifting device 100 moves the box 400 carried on the transport robot from the first handover position 111 to the first buffer position 112. The box translation device 300 picks up and transfers the box 400 from the first buffer position 112. The box 400 can be picked up during its movement on the box translation device 300. The picked box 400 is transported to the second buffer position 212 by the box translation device 300. The second lifting device 200 then transports the box 400 from the second buffer position 212 to the second handover position 211 and hands it over to the transport robot. After picking up the box 400 at the second handover position 211, the transport robot carries it away from the picking station. By using the above method, the transport robot can be decoupled from the material box 400 after transporting it to the picking station. It no longer needs to wait with the material box 400 for the picking operation to be completed, reducing the waiting time of the transport robot. This reduces the number of transport robots used, avoids queuing and congestion of transport robots at the picking station, improves the utilization rate or turnover rate of transport robots, saves costs, and also improves the working efficiency of the sorting station.
[0033] In some embodiments, such as Figure 1 As shown, the hopper translation channel is provided with a plurality of sorting positions 320 for accommodating hoppers 400. These sorting positions 320 are located between the first buffer position 112 and the second buffer position 212, and the sorting positions 320, the first buffer position 112, and the second buffer position 212 can accommodate the hoppers 400 without interfering with each other. When the hopper 400 is located at a sorting position 320, a picking operation can be performed. There can be one or more sorting positions 320. It is understandable that when there are multiple sorting stations 320, the sorting stations 320 can also be used as buffer positions for temporary storage bins 400. The bins 400 on multiple sorting stations 320 can be picked simultaneously, or only the bins 400 on one sorting station 320 can be picked, and the remaining sorting stations 320 are used as temporary storage bins 400. The temporary storage bins 400 include bins 400 temporarily stored for picking and bins 400 temporarily stored for picking and ready to leave the station. The sorting station 320 is provided with at least one bin 400 that can be accommodated without interfering with the first buffer position 112 and the second buffer position 212. That is, the sorting station 320, the first buffer position 112 and the second buffer position 212 can each carry at least one bin 400 at the same time, so as to ensure that the first lifting device 100, the second lifting device 200 and the bin translation device 300 can operate simultaneously without interfering with each other.
[0034] In some embodiments, such as Figure 1As shown, the picking station also includes a passageway for the transport robot to pass through. The passageway connects the first handover position 111 and the second handover position 211. The first carrier component 120 and the second carrier component 220 respectively hand over the material box 400 to the transport robot at the first handover position 111 and the second handover position 211. The first handover position 111 is used for the first carrier component 120 to hand over the material box 400 to the transport robot, and the second handover position 211 is used for the second carrier component 220 to hand over the material box 400 to the transport robot. For example, the first handover position 111 is used for the first carrier component 120 to pick up the material box 400 from the transport robot, and the second handover position 211 is used for the second carrier component 220 to place the material box 400 on the transport robot. The passageway is a spatial channel through which the transport robot can pass. The passageway between the first handover position 111 and the second handover position 211 allows the transport robot to hand over the material box 400 to be picked. After reaching the first carrying component 120, the robot quickly moves to the second handover position 211 to pick up another picked box 400. Specifically, the transport robot transports the box 400 to be picked to the first handover position 111. During this process, the first carrying component 120 removes the box 400 from the transport robot and moves it to the first buffer position 112. Simultaneously, the transport robot moves along the passageway from the first handover position 111 to the second handover position 211. After the transport robot reaches its position, the second carrying component 220 places another picked box 400 onto the transport robot, which then transports the box 400 to the designated location. By setting up a passageway, the transport robot can easily enter the second handover position 211 to perform its transport task, thus improving efficiency.
[0035] In some embodiments, both the first support component 120 and the second support component 220 include two sets of vertically paired slide rails 224. A first clamping arm and a second clamping arm are slidably connected within each of the two sets of slide rails 224. The first clamping arm and the second clamping arm are arranged opposite each other in the horizontal direction and can slide synchronously within the slide rails 224. Both the first support component 120 and the second support component 220 include a set of robotic arms that slide within the slide rails 224. In this embodiment, the first support component 120 and the second support component 220 are designed with the same structure. The first clamping arm and the second clamping arm are arranged opposite each other and have the same structure. The first clamping arm and the second clamping arm respectively support the two sides or the two sides of the bottom of the material box 400. The material box 400 is moved by the synchronous sliding of the first clamping arm and the second clamping arm along the vertical slide rails 224.
[0036] In some embodiments, such as Figure 3As shown, the first clamping arm and the second clamping arm can form a first connection state and a second connection state relative to the slide rail 224 and slide within the slide rail 224. When the first clamping arm and the second clamping arm form the first connection state relative to the slide rail 224, the first clamping arm and the second clamping arm can move relative to the material box 400 along both sides of the material box 400. When the first clamping arm and the second clamping arm form the second connection state relative to the slide rail 224, the first clamping arm and the second clamping arm can support the material box 400 and drive the material box 400 to move along the slide rail 224. To enable the first and second gripping arms to vertically transport the material box 400, they must first be slidably connected to the slide rail 224. Furthermore, when the transport robot is positioned at the first handover position 111 carrying the material box 400, the first and second gripping arms need to move from above the material box 400 to its bottom or side. During this movement, it is crucial to ensure that the first and second gripping arms can avoid interfering with the material box 400. When the first and second gripping arms are supporting the material box 400 from its bottom or side and moving upwards, the first gripping arm... The first clamping arm and the second clamping arm abut against the bottom or side of the material box 400. Therefore, the first clamping arm and the second clamping arm need to form at least two relative positional relationships with the slide rail 224. That is, the first connection state in which the first clamping arm and the second clamping arm can move relative to the material box 400 along both sides of the material box 400, and the second connection state in which the first clamping arm and the second clamping arm can support the material box 400 and drive the material box 400 to move along the slide rail 224. By setting a connecting mechanism, the first clamping arm and the second clamping arm can form the first connection state and the second connection state relative to the slide rail 224 and can switch between the two states.
[0037] Specifically, such as Figure 3As shown, both the first clamping arm and the second clamping arm include a support arm 221 arranged in a horizontal direction. Both ends of the support arm 221 are hinged to a first connecting rod 222. Each set of slide rails 224 includes a first slide rail 224 and a second slide rail 224 arranged opposite to each other. A slider 225 is provided in both the first slide rail 224 and the second slide rail 224. The first connecting rod 222 is hinged to the slider 225. The slider 225 is also slidably connected to a second connecting rod 223. The second connecting rod 223 is also hinged to either the first connecting rod 222 or the support arm 221. By setting a first connecting rod 222 that is hinged to the support arm 221 and the slider 225 respectively, the support arm 221 and the slide rail 224 (slider 225) can form a first connection state and a second connection state. By setting a second connecting rod 223 that is slidably connected to the slider 225 and hinged to the support rod or the first connecting rod 222, the support arm 221 can be positioned in the first connection state and the slide rail 224 and can switch between the two connection states. By controlling the tilt angle of the second connecting rod 223, the position of the support arm 221 relative to the slide rail 224 can be controlled. For example, if the second connecting rod 223 is controlled to coincide with the slide rail 224 in the vertical plane, the support arm 221 will be constricted between the two slide rails 224. If the second connecting rod 223 is controlled to form the maximum included angle with the slide rail 224, the support arm 221 will be away from the slide rail 224 and can abut against the material box 400.
[0038] In some embodiments, the support arm 221 includes a drive mechanism for driving the hopper 400 to move horizontally, enabling the first support assembly 120 or the second support assembly 220 to transfer the hopper 400 to the third support assembly 310, and enabling the third support assembly 310 to transfer the hopper 400 to the first support assembly 120 or the second support assembly 220. By providing a drive mechanism on the support arm 221, after transporting the hopper 400 to the first buffer position 112, the support arm 221 can drive the hopper 400 horizontally to the hopper translation channel, and enable the support arm 221 to pick up the hopper 400 from the hopper translation channel and fully enter the second buffer position 212. Specifically, the drive mechanism includes a conveyor belt and / or conveyor rollers 2211, and the third support assembly 310 includes a conveyor line. By docking the conveyor belt or conveyor rollers 2211 with the conveyor line, the hopper 400 can be transferred between them. Figure 4 The driving mechanism includes several conveying rollers 2211 arranged along the extension direction of the support arm 221. The conveying rollers 2211 are driven to rotate by a drive motor and transmission gears, and the rotation of the conveying rollers 2211 causes the material box 400 carried on the support arm 221 to move.
[0039] In addition, to achieve the above objectives, such as Figure 1As shown, this application also provides a warehousing system, including a picking station and a transport robot. The picking station is configured as described in any of the above embodiments. The transport robot is capable of entering the first lifting channel and the second lifting channel of the picking station, and is capable of transferring the material box 400 to the first bearing component 120 at the first handover position 111, and receiving the material box 400 transferred by the second bearing component 220 at the second handover position 211.
[0040] In this embodiment, after the transport robot enters the first lifting channel, it can deliver the box to the first handover position of the first carrier component without stopping to wait for the picking operation; thereafter, it can directly enter the second lifting channel and pick up another box that has been picked from the second handover position of the second carrier component, thus decoupling the transport robot from the picking station operation process.
[0041] In summary, the picking station and warehousing system of this embodiment can improve the utilization and turnover rate of transport robots, increase sorting efficiency, and save costs.
