Detailed Implementation
[0046] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.
[0047] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0048] Furthermore, in this application, directional terms such as "upper," "lower," "inner," and "outer" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.
[0049] Figure 1 This is a schematic diagram of the structure of a warehousing system provided in an embodiment of this application.
[0050] like Figure 1 As shown, the warehousing system may include a storage area 100 and a picking area 200.
[0051] In some examples, storage area 100 may include multiple vehicles 110 to store items.
[0052] In some examples, vehicle 110 may have multiple storage layers, each of which may include multiple storage slots, each capable of holding items. This allows for efficient use of the space in storage area 100 to accommodate more items.
[0053] It should be noted that the items placed in the storage location may include, but are not limited to, goods, containers containing goods (such as bins), pallets, packages containing goods, and original packaging boxes containing goods.
[0054] In some examples, vehicle 110 can be a stationary vehicle 110 or a mobile vehicle 110. This increases the flexibility of item storage.
[0055] For example, the carrier 110 can be a shelf, support frame, etc. Storage positions, cache positions, and temporary storage positions can be formed on the shelf or support frame.
[0056] In some examples, picking area 200 is used to complete picking or sorting operations.
[0057] In some examples, picking or sorting can be done by stocking, which means selecting and classifying items of the same type and then placing them on shelves so that multiple items of the same type can be quickly retrieved and stocked during the next outbound shipment.
[0058] In some examples, picking or sorting can be outbound picking, that is, the items in an order can be selected and sorted based on order requirements in order to facilitate order delivery.
[0059] It should be noted that picking or sorting work can also be the sorting of items such as unpacking and replenishing, which is not specifically limited in this embodiment.
[0060] In some examples, picking area 200 includes at least one workstation 300, each of which is capable of independent picking operations. Having multiple workstations 300 in picking area 200 can effectively improve picking efficiency, respond promptly to order demands, and increase order delivery efficiency.
[0061] Figure 2 This is a partial structural diagram of a workstation provided in an embodiment of this application.
[0062] Figure 3 This is a schematic diagram of a workstation without a fall protection platform, provided in an embodiment of this application.
[0063] Combination Figure 2 and Figure 3As shown, workstation 300 includes sorting station 310 and fall protection platform 320.
[0064] like Figure 3 As shown, for example, all sorting stations 310 can be used to hold the first container 301. The first container 301 is used to place the target item, which may be an item sorted from the storage area 100.
[0065] In some examples, sorting stations 310 can be set on sorting platform 330, which can have two sorting stations 310, each capable of holding one first container 301. This allows two first containers 301 to be placed on the sorting platform 330, enabling simultaneous sorting of different orders and improving sorting efficiency.
[0066] Combination Figure 2 and Figure 3 As shown, for example, the anti-fall platform 320 can be installed above the sorting station 310, and each sorting station 310 is provided with a sorting port 321. In this way, during item sorting, the target item can enter the first container 301 through the sorting port 321. Simultaneously, during the transfer of the target item, the anti-fall platform 320 can catch any falling target items, preventing them from accidentally falling to the sorting station 310 or other locations in the workstation 300 and affecting subsequent operations. The anti-fall platform 320 effectively prevents target items from accidentally falling from the picking equipment 380 due to improper operation or equipment malfunction during the picking process, thus avoiding damage to items or chaos in the work area, improving the safety of the workstation 300 and the efficiency of the picking operation.
[0067] In some examples, the size of the sorting port 321 is often smaller than the size of the first container 301. In other words, the first container 301 cannot directly leave or enter the sorting station 310 from the sorting port 321. Therefore, there is an opening 331 between the fall arrestor platform 320 and the sorting station 310, through which the first container 301 can enter or leave the sorting station 310.
[0068] For example, the opening 331 can be set on either side of the sorting station 310 between the bearing surface of the first container 301 and the anti-fall platform 320.
[0069] Figure 4 This is a schematic diagram of the sorting platform provided in the embodiments of this application.
[0070] like Figure 4 As shown, for example, when multiple sorting stations 310 are set on the sorting platform 330, the multiple sorting stations 310 can be arranged along the length direction of the sorting platform 330 (e.g., ...). Figure 4 The openings 331 can be arranged side-by-side along the width direction of the sorting platform 330 (e.g., along the x-axis). Figure 4 The opening 331 is located on one side of the y-axis direction. Thus, the opening 331 corresponds to each sorting station 310, and the first container 301 at each sorting station 310 can leave or enter the sorting station 310 through the opening 331. Simultaneously, the opening 331 covers each sorting station 310 and prevents the entry and exit of the first containers 301 at each sorting station 310 from interfering with each other. That is, the first containers 301 at each sorting station 310 can enter and exit the sorting station 310 independently, thereby improving sorting efficiency.
[0071] In other examples, opening 331 may also be provided along the length of sorting platform 330 (e.g., ...). Figure 4 (in the x-axis direction). At this time, the first container 301 on multiple sorting stations 310 needs to enter or leave the sorting station 310 one by one.
[0072] During the sorting process, workers may accidentally crawl into the opening 331. In other words, workers may enter the area between the sorting station 310 and the fall arrestor platform 320 through the opening 331. At this time, the workers located between the sorting station 310 and the fall arrestor platform 320 may become stuck, or other equipment in the workstation 300 may injure the workers through the sorting opening 321 while it is operating, thus endangering the safety of the workers.
[0073] Combination Figure 2 and Figure 4 As shown, to avoid the aforementioned situation, workstation 300 further includes a first detection component 341 and a control system (not shown in the figure). The first detection component 341 can be configured to correspond to the opening 331, enabling it to detect whether an object passes through or approaches the opening 331. Simultaneously, the control system can be communicatively connected to the first detection component 341. When the first detection component 341 detects that an object has passed through or approached the opening 331, the control system can send control commands to some working devices within workstation 300 to cause those devices to perform corresponding actions.
[0074] For example, the control system can be the control center or management system of a warehousing system.
[0075] In one example, the control command could be an instruction to stop the work equipment from operating. This allows the work equipment to stop operating based on the control command, thus preventing harm to workers.
[0076] In another example, the control command could be an instruction to reduce the operating speed of the work equipment. In this way, the work equipment can reduce its operating speed based on the control command to avoid causing harm to the workers.
[0077] In another example, the control command could be an instruction to control the working device to operate within a safe working range. In this way, the working device can operate within a safe range (such as a range maintaining a safe distance from opening 331) based on the control command.
[0078] In another example, the control command could be an instruction to move the work equipment to a safe position. In this way, the work equipment can move to a preset safe position based on the control command, thereby avoiding harm to the worker.
[0079] It is understood that control commands can also be other related commands used to protect the safety of staff, and no limitation is made to control commands in this embodiment.
[0080] In addition, some of the working equipment within workstation 300 may include the sorting platform 330 or other equipment within workstation 300, which is not limited in this embodiment.
[0081] In the workstation 300 provided in this embodiment, a first detection component 341 is installed at an opening 331 to detect whether an object passes through or approaches the opening 331. If the first detection component 341 detects an object passing through or approaching the opening 331, a worker may crawl into the opening 331, posing a safety hazard. In this case, the control system can send control commands to some working devices within the workstation 300 based on the detection results of the first detection component 341, causing the working devices to perform corresponding actions. This prevents the working devices within the workstation 300 from causing harm to the worker's personal safety, thus protecting the worker. In this way, through the coordinated setup of the first detection component 341 and the control system, safety protection for the workstation 300 can be achieved, improving the safety of workstation operations.
[0082] In one example, the worker may pass through opening 331 with part of their body (such as an arm) to enter the area between sorting station 310 and fall arrest platform 320. Alternatively, the worker may pass through opening 331 with their entire body to enter the area between sorting station 310 and fall arrest platform 320. In this embodiment, the specific form in which the worker passes through opening 331 is not limited.
[0083] In another example, a worker can approach the opening 331 when the distance between the worker's body and the opening 331 is less than a preset distance threshold. In this case, it can be confirmed that the worker has approached the opening 331.
[0084] For example, the first detection component 341 may include a safety light curtain.
[0085] For example, taking the detection of whether an object is passing through an opening using a safety light curtain, the safety light curtain is an array of paired infrared beams.
[0086] In one example, the safety light curtain may include a transmitter and a receiver, with the transmitter and receiver positioned opposite each other on either side of the opening 331. The transmitter is configured to output an array of infrared beams, and the receiver is configured to receive the array of infrared beams.
[0087] In this way, the infrared beam array forms a "light wall" between the transmitter and the receiver. When there is no obstruction between the transmitter and receiver, the receiver can receive all the infrared beams emitted by the transmitter, thus determining that no object has passed through opening 331. When there is an obstruction between the transmitter and receiver, the receiver cannot receive all the infrared beams emitted by the transmitter, thus determining that an object has passed through opening 331.
[0088] In other examples, the first detection component 341 may also be one or more of a detection camera, a security lidar, a security ultrasonic radar, a security radio frequency identification (RFID) detector, or other security detection equipment, and this application does not limit this.
[0089] It should be noted that when the first detection component 341 is a safety light curtain, a detection camera, or a safety lidar, in addition to detecting the position directly opposite the opening 331, it can also emit detection waves within a certain range to detect the distance between the object and the opening 331, thereby determining whether an object is approaching the opening 331 based on a preset distance threshold. In other words, the detection of whether an object has passed through or approached the opening 331 by the first detection component 341 can be achieved by adjusting the detection range of the detection device, which is not limited in this embodiment.
[0090] In some examples, when the first container 301 passes through the opening 331, the first detection component 341 can be in a closed state for a preset time period. In this way, when the first container 301 passes through the opening 331, the first detection component 341 does not need to detect whether an object is passing through, thereby avoiding false alarms caused by the first container 301 passing through the opening 331, so as to avoid affecting work efficiency.
[0091] For example, the preset time period can be determined based on the time required for the first container 301 to pass through the opening 331, specifically it can be 1s, 3s, 5s, etc., and is not limited in this embodiment.
[0092] Figure 5 This is a structural schematic diagram of the sorting platform, loading and unloading equipment, and seeding wall provided in the embodiments of this application.
[0093] Combination Figure 2 , Figure 3 and Figure 5 As shown, in some examples, workstation 300 also includes seeding wall 350 and loading / unloading equipment 360.
[0094] For example, the seeding wall 350 of the workstation 300 can be used to place the first container 301. The first container 301 can be an empty container without any items, or it can be a fully loaded container filled with items, or it can be a container between an empty state and a fully loaded state.
[0095] For example, the seeding wall 350 can be a carrier. The seeding wall 350 can have multiple storage layers, each storage layer having multiple storage slots to store more first containers 301.
[0096] For example, the seeding wall 350 may also have a buffer space for placing the first container 301 that is ready for transfer.
[0097] In some examples, the loading and unloading equipment 360 is able to transfer the first container 301 between the seed wall 350 and the sorting station 310.
[0098] For example, the loading and unloading equipment 360 is arranged adjacent to the sorting platform 330. The loading and unloading equipment 360 can transfer the first container 301 that is already full of items on the sorting platform 330 to the seeding wall 350, or the loading and unloading equipment 360 can also transfer the first container 301 on the seeding wall 350 to the sorting platform 330.
[0099] For example, a coordinate system is established with the height direction of the seeding wall 350 as the z-axis direction, the length direction of the seeding wall 350 as the x-axis direction, and the width direction of the seeding wall 350 as the y-axis direction for illustration.
[0100] For example, along the y-axis, the seeding wall 350, the loading / unloading device 360, and the sorting platform 330 are arranged sequentially. This allows the loading / unloading device 360, located between the sorting platform 330 and the seeding wall 350, to facilitate the transfer of the first container 301. Simultaneously, the loading / unloading device 360 can be arranged adjacent to the opening 331 of the sorting platform 330. In this case, the first detection component 341 can be positioned on the loading / unloading device 360 corresponding to the opening 331.
[0101] In some examples, the first detection component 341 is in a closed state during the process of the loading and unloading equipment 360 placing the first container 301 on the sorting station 310 and during the process of the loading and unloading equipment 360 removing the first container 301 from the sorting station 310. In this way, the first detection component 341 is in a closed state when the first container 301 passes through the opening 331, thereby avoiding false alarms.
[0102] Combination Figure 5 As shown, in some examples, loading and unloading equipment 360 may include a support frame 361 and a pick-and-place device 362.
[0103] For example, the first detection component 341 may be disposed on the support frame 361. Alternatively, the first detection component 341 may also be disposed on the sorting platform 330, without limitation.
[0104] For example, the pick-and-place device 362 is disposed on the support frame 361, and the pick-and-place device 362 can move relative to the support frame 361 along a first direction and a second direction. In this way, the pick-and-place device 362 can move relative to the support frame 361 to the opening 331 to pick up or place the first container 301. The first direction and the second direction are different directions.
[0105] For example, the first direction can be the z-axis direction, and the second direction can be the x-axis direction of the seeding wall 350. In this way, the picking and placing device 362 can perform lifting and translating movements relative to the support frame 361, so as to move to the position corresponding to the designated storage position on the seeding wall 350, thereby enabling the first container 301 to be placed on the designated storage position or the first container 301 to be taken out from the designated storage position.
[0106] For example, the pick-and-place device 362 can pick up and place the first container 301 using at least one of the following structures: suction cup, gripping fork, hook, finger, and magnetic structure. In this embodiment, the specific structure of the pick-and-place device 362 is not limited.
[0107] In some examples, the loading / unloading device 360 may also include a second detection component (not shown). The second detection component is capable of detecting whether the loading / unloading device 362 is close to the opening 331, so that the first detection component 341 can switch its operating state based on the detection result of the second detection component.
[0108] For example, when the second detection component detects that the pick-and-place device 362 is approaching the opening 331, it indicates that the pick-and-place device 362 is about to pick up or place the first container 301. At this time, the first detection component 341 can be in a closed state to avoid false alarms when the pick-and-place device 362 and the first container 301 pass through the opening 331.
[0109] For example, when the second detection component does not detect the pick-up and put-down device 362 approaching the opening 331, it means that the first container 301 will not pass through the opening 331 at this time. At this time, the first detection component 341 can be in the open state to detect objects passing through the opening 331.
[0110] For example, the second detection component may be a displacement sensor, a pressure sensor, etc.
[0111] Taking the second detection component as a pressure sensor as an example, the pressure sensor can be set on the support frame 361 and corresponding to the opening 331. When the pick-and-place device 362 needs to move to the position of the opening 331, the pressure of the pick-and-place device 362 on the support frame 361 corresponding to the position of the opening 331 will change. At this time, it can be determined whether the pick-and-place device 362 is close to the opening 331 based on the pressure change of the pressure sensor.
[0112] It should be noted that the second detection component can also be an infrared sensor, a detection camera, etc., and is not limited in this embodiment.
[0113] In some examples, in order to raise workers’ awareness of safe operation, safety signs can be set on the surface of the fall arrestor platform 320 away from the first container 301 to remind workers to be careful of getting their hands caught or not to step on it, thereby achieving the purpose of reminding workers of safety.
[0114] For example, security identifiers may include image identifiers, text identifiers, and combinations of image and text identifiers, etc. In this embodiment, the specific form of security identifiers is not limited.
[0115] Please refer to it again. Figures 1 to 3 In some examples, workstation 300 may also include transport equipment 370.
[0116] In some examples, transport equipment 370 can transport items to be sorted in storage area 100 to docking position 303 in workstation 300.
[0117] In some examples, when transporting items to be sorted, the transport equipment 370 can carry them in a second container 302, so that the transport equipment 370 can transport multiple items to be sorted in one transport process to improve transport efficiency.
[0118] In some examples, the second container 302 may be transported to the storage area 100 by the transport device 370 to hold items stored in the storage area 100. Alternatively, the second container 302 may be stored in the storage area 100 and be an empty container. Or, it may be stored in the storage area 100 and contain items. In this embodiment, the source of the second container 302 is not limited.
[0119] In some examples, the second container 302 may be a storage box. Alternatively, in other examples, the second container 302 may be a pallet, carton, or other structure capable of carrying items, which is not limited in this embodiment.
[0120] In some examples, transport equipment 370 can be a conveyor line, such as a conveyor line formed by a conveyor structure such as a conveyor belt or conveyor chain.
[0121] For example, the conveyor inlet of the conveyor line may be located in storage area 100.
[0122] In some examples, the delivery outlet may be located at docking station 303 of workstation 300. In this case, the second container 302 transported to docking station 303 can be moved back to storage area 100, moved to another workstation 300, or moved to another location by a robot.
[0123] In other examples, the conveyor line can also transport the second container 302. The conveyor line can transport the second container 302 to the picking area 200. At this point, the conveyor line can pause, and the items in the second container 302 can be picked. After picking is complete, the conveyor line can continue operating to transport the second container 302 away.
[0124] For example, after picking is completed, the conveyor line can directly transport the second container 302 back to the storage area 100 or to another picking area 200. In this way, the subsequent handling of the second container 302 after picking can be eliminated, thereby improving transportation and picking efficiency.
[0125] Furthermore, a conveyor line can pass through one or more picking areas 200. In this way, a single conveyor line can simultaneously transport the second container 302 to each picking area 200, thereby further improving transport and picking efficiency.
[0126] Figure 6 This is a structural schematic diagram of a transportation device provided in an embodiment of this application.
[0127] Combination Figure 6 As shown, in other examples, transport equipment 370 may include a transport robot.
[0128] For example, the transport robot may include a mobile chassis 371 and a carrying mechanism 372.
[0129] In some examples, the mobile chassis 371 can move the carrier mechanism 372 between the workstations 300 in the storage area 100 and the picking area 200.
[0130] For example, the mobile chassis 371 can be a chassis capable of four-way movement or a chassis capable of omnidirectional movement; this embodiment is not limited to any particular type.
[0131] In some examples, the carrying mechanism 372 includes a carrying component 3721 and a lifting component 3722. One end of the lifting component 3722 is connected to the mobile chassis 371, and the other end is connected to the carrying component 3721. The lifting component 3722 can drive the carrying component 3721 to rise and fall relative to the mobile chassis 371. The carrying component 3721 can be used to carry a second container 302 containing items to be sorted. Thus, when the transport equipment 370 is transporting items, the lifting component 3722 can lower the second container 302 to reduce the center of gravity and improve stability. After the transport equipment 370 transports the items to the workstation 300, the lifting component 3722 can raise the second container 302 relative to the mobile chassis 371, thereby elevating the second container 302 to facilitate sorting.
[0132] Figure 7 This is a top view of the first type of workstation provided in the embodiments of this application.
[0133] Combination Figure 2 , Figure 3 and Figure 7 As shown, in some examples, workstation 300 may also include picking equipment 380, which is disposed adjacent to sorting station 310, and docking station 303 is disposed adjacent to picking equipment 380, so as to facilitate the sorting of items to be sorted into first container 301 on sorting station 310. In this way, the working range of picking equipment 380 can cover sorting station 310 and docking station 303.
[0134] In some examples, the docking station 303 may also be set adjacent to the picking device 380, which makes it easier for the picking device 380 to sort the items to be sorted in the first container 301 into the first container 301.
[0135] For example, the docking position 303 can be located on one side of the picking device 380 along the x-axis. In this way, when the picking device 380 moves between the first container 301 and the second container 302, the rotation angle is smaller, which can improve the transfer speed of items.
[0136] In some examples, the picking device 380 can pick up and place items to be sorted in the first container 301 using at least one of the following structures: suction cup, gripper fork, hook, finger pick, and magnetic structure.
[0137] Compared to the workstation 300 where sorting is done by operators, the sorting equipment 380 enables 24-hour uninterrupted sorting, timely order response, and improved sorting efficiency.
[0138] In some examples, the picking device 380 can be a robotic arm. After the robotic arm picks up the target item at the picking port 322, it can sort the target item into the first container 301 at the target location by rotating at different angles.
[0139] In some examples, the picking device 380 may also be a mechanism similar to the loading and unloading device 360. It is understood that in this embodiment, the picking device 380 is only described as a robotic arm and is not intended to be a specific limitation.
[0140] It should be noted that in other examples, workstation 300 may not be equipped with picking equipment 380, and the target items may be picked by staff.
[0141] In this embodiment, the work equipment in workstation 300 may include loading and unloading equipment 360, picking equipment 380, and transport equipment 370, etc. Preventing workers from accidentally entering opening 331 can avoid injury to workers during operation by these work equipment, thereby achieving safe operation.
[0142] Figure 8 This is a simplified side view of a fall-prevention platform, transportation equipment, and a second container provided in an embodiment of this application.
[0143] Combination Figure 2 , Figure 3 and Figure 7 and Figure 8 As shown, the anti-fall platform 320 can also be installed above the docking position 303, and the anti-fall platform 320 is provided with a picking port 322 corresponding to the docking position 303. In this case, the target item in the second container 302 can be picked out through the picking port 322. During the process of picking the target item from the second container 302 to the first container 301, the anti-fall platform 320 can catch the falling target item, thereby preventing the target item from falling onto the transport path of the transport equipment 370 and affecting the normal operation of the transport equipment 370, thus improving sorting efficiency.
[0144] In some examples, the transport device 370 can transport the second container 302 to the docking position 303, positioning the second container 302 below the picking port 322. A gap may be provided between the fall arrestor platform 320 and the second container 302, providing a safety margin for workers or robotic arms. This gap prevents the second container 302 from contacting the worker's hand if the worker's hand passes through the picking port 322, thus preventing injury to the worker's hand from the moving second container 302 during transport device 370 operation.
[0145] For example, the gap can be 20mm to 35mm. Specifically, it can be 20mm, 25mm, 30mm, 35mm, etc., so as to allow for a safety margin while avoiding an excessively large gap, thereby facilitating the picking of target items from the second container 302.
[0146] For example, when workstation 300 is not in operation, it may be under maintenance or inspection, and picking port 322 connects the workspace of workstation 300 with the transport space of transport equipment 370. At this time, if a worker enters the transport space of transport equipment 370 through picking port 322, the operation of transport equipment 370 may pose a threat to the worker's safety.
[0147] In some examples, workstation 300 also includes a third detection component 342, which is configured corresponding to the picking port 322. The third detection component 342 is activated when workstation 300 is not in operation and detects whether an object passes by or approaches the picking port 322. Thus, even when workstation 300 is not in operation, the third detection component 342 can detect whether an object passes by or approaches the picking port 322. Simultaneously, the third detection component 342 can communicate with the control system, allowing the control system to send control commands to the transport equipment 370 when the third detection component 342 detects that an object has passed by or approached, thereby controlling the transport equipment to perform corresponding actions.
[0148] In one example, the control command could be an instruction to stop the transport equipment 370 from operating. This way, if a transport equipment 370 is in operation, it can be controlled to stop, thereby preventing the operating transport equipment 370 from causing harm to workers passing through the picking gate 322, thus protecting the workers.
[0149] In another example, the control command could be an instruction to reduce the operating speed of the transport equipment 370. In this way, if a transport equipment 370 is in operation, its operating speed can be reduced, thereby preventing the rapidly operating transport equipment 370 from causing harm to workers passing through the picking gate 322, thus protecting the workers.
[0150] In another example, the control command could be an instruction to control the transport equipment 370 to operate within a safe range. Thus, if a transport equipment 370 is in operation, it can be controlled to operate within a safe range, thereby preventing the operating transport equipment 370 from causing harm to workers passing through the picking gate 322, thus protecting the workers.
[0151] In another example, the control command could be an instruction to control the transport equipment 370 to move to a designated position. In this way, if a transport equipment 370 is in operation, it can be controlled to move to a designated position, thereby preventing the operating transport equipment 370 from causing harm to workers passing through the picking gate 322, thus protecting the workers. The designated position could include the position corresponding to other workstations 300; or it could be the location of a storage area; or it could be the maintenance position of the transport equipment 370, etc., which is not limited in this embodiment.
[0152] It is understood that the control commands can also be other related commands for the purpose of protecting the safety of the staff, and this embodiment does not limit them.
[0153] In one example, the worker passing through the picking port 322 may be the worker's entire body passing through the picking port 322, or part of the worker's body (such as an arm or a leg) passing through the picking port 322. In this embodiment, the specific form of the worker passing through the picking port 322 is not limited.
[0154] In another example, a worker approaching the picking port 322 can be when the distance between the worker and the picking port 322 is less than a preset distance threshold.
[0155] For example, when the workstation 300 is in normal working condition, the third detection component 342 is in the off state. This can prevent the third detection component 342 from mistaking the target items passing through the picking port 322 for staff members, thereby reducing the possibility of false alarms.
[0156] For example, the third detection component 342 may be one or more of a grating, a detection camera, a security lidar, a security ultrasonic radar, a security radio frequency identification detector, or other security detection equipment, and this application does not limit it.
[0157] It should be noted that the specific detection principle of the third detection component 342 regarding passing or approaching can be referred to the description of the first detection component 341, and will not be repeated here.
[0158] Figure 9 This is a top view of a fourth detection component and a second container (transport robot) provided in an embodiment of this application.
[0159] Combination Figure 8 , Figure 9 As shown, in some examples, workstation 300 also includes a fourth detection component 343, which is configured corresponding to docking position 303. Thus, the fourth detection component 343 can detect whether docking position 303 has a second container 302.
[0160] For example, when workstation 300 needs maintenance or inspection, if the fourth detection component 343 detects that the docking position 303 has a second container 302, it means that the transport equipment 370 has already transported the second container 302 to below the picking port 322. To prevent injury to the worker's arm or robotic arm from movement of the second container 302 when it passes through the picking port 322, the transport equipment 370 can be stopped by the control system, thereby protecting the worker and the robotic arm.
[0161] Figure 10 This is a top view of a simplified diagram of the second type of workstation provided in this application embodiment.
[0162] Combination Figure 8 , Figure 9 and Figure 10 As shown, in some examples, workstation 300 also includes a security unit 390. The security unit 390 can be communicatively connected to the third detection component 342 and the fourth detection component 343.
[0163] For example, the safety unit 390 may be a button box located outside the workspace of workstation 300. The button box may include an emergency stop button and a safety lock. The emergency stop button can control workstation 300 to stop working in an emergency, and the safety lock, in conjunction with a safety key, allows personnel to change the state of the safety lock using the safety key when they wish to enter the workspace of workstation 300, thereby controlling the relevant equipment to stop operating.
[0164] In other examples, the security unit 390 may also be a security touch panel, but this embodiment is not limited to that.
[0165] For example, the safety unit 390 includes a silent state (off state) and an open state (on state). When the working equipment in the workstation 300 is operating normally and the workstation 300 is in normal working condition, the safety unit 390 can be in the silent state; when the working equipment in the workstation 300 is not operating normally, that is, when the workstation 300 is in a stopped working state, if the staff needs to enter the workspace of the workstation 300 for inspection and maintenance, then the staff can open the safety unit 390.
[0166] Accordingly, when the safety unit 390 is in a silent state, the third detection component 342 and the fourth detection component 343 can be in a closed state. This means that the equipment within the workstation 300 can perform normal sorting operations without requiring the third detection component 342 and the fourth detection component 343 to perform safety checks. When the safety unit 390 is in an open state, it indicates that personnel need to enter the workspace of the workstation 300 for inspection and maintenance. In this case, the third detection component 342 and the fourth detection component 343 can be activated to initiate safety checks and protect the safety of the personnel.
[0167] In some examples, the safety unit 390 is communicatively connected to the control system.
[0168] For example, the transport equipment 370 may include a transport robot, and the warehousing system may have multiple transport robots, with each workstation 300 corresponding to multiple transport robots to transport the second container 302.
[0169] In some examples, when safety unit 390 is in the open state, the control system can stop the transport robot located at docking position 303 and simultaneously relocate transport robots not at docking position 303 to designated locations (such as other workstations, storage areas, etc.). This way, when workers are performing maintenance or inspections within workstation 300, there are no moving transport robots near picking port 322, thus preventing damage to workers or robotic arms.
[0170] In some examples, workstation 300 may include a security fence 391.
[0171] like Figure 10 As shown, for example, the safety fence 391 can enclose the perimeter of the workstation 300, that is, the space enclosed by the safety fence 391 can include the space where each device is located within the workstation 300 and the first operating area 304. In this way, the safety fence 391 can separate the device space within the workstation 300 and the first operating area 304 from the second operating area 305.
[0172] Meanwhile, passageways for transport robots to enter and exit can be set on opposite sides of the safety fence 391, and the fifth detection component 344 can be set at the passage position of the safety fence 391 to detect whether a transport robot is moving between the first operating area 304 and the second operating area 305.
[0173] For example, the fourth detection component 343 may be mounted on the safety fence 391.
[0174] In some examples, workstation 300 may also include a safety door 392 mounted on a safety fence 391. This allows workers to enter and exit the workspace of workstation 300 through the safety door 392.
[0175] For example, when the safety unit 390 is in a silent state, the safety door 392 can be in a closed state, meaning that the equipment in the workstation 300 is performing sorting work normally, and personnel do not need to enter the workstation 300 to work. When the safety unit 390 is in an open state, the safety door 392 can be in an open state, at which time personnel can enter the workspace of the workstation 300 through the safety door 392 to perform inspections and maintenance.
[0176] For example, the fourth detection component 343 may be disposed on the ground corresponding to the location of the dock 303.
[0177] like Figure 9 As shown, exemplarily, the fourth detection component 343 includes a first sensor 3431 and a second sensor 3432, which are arranged adjacent to each other, and both the first sensor 3431 and the second sensor 3432 correspond to the docking position 303. It can be seen that the first sensor 3431 and the second sensor 3432 correspond to two different positions of the docking position 303. Thus, the presence of an object in the docking position 303 can be determined based on the detection results of the first sensor 3431 and the second sensor 3432, thereby improving the accuracy of detecting whether an object exists in the docking position 303.
[0178] For example, when the safety door 392 is in the open state, the first sensor 3431 and the second sensor 3432 can detect whether there is an object in the parking position 303.
[0179] Simultaneously, by using the first sensor 3431 and the second sensor 3432 to jointly detect the docking position 303, it is also possible to determine whether the transport robot has moved into place. For example, if the first sensor 3431 and the second sensor 3432 simultaneously detect an object in the docking position 303, it indicates that the transport robot has completely moved into the docking position 303. At this time, the second container 302 on the transport robot corresponds exactly to the picking port 322. If only the first sensor 3431 or the second sensor 3432 detects an object in the docking position 303, it indicates that part of the transport robot's structure is in the docking position 303, but not completely. In this case, the second container 302 on the transport robot does not completely correspond to the picking port 322, and the transport robot may be moving.
[0180] In some examples, the first sensor 3431 and the second sensor 3432 are communicatively connected to the control system. Thus, the control system can shut down the third detection component 342 when both the first sensor 3431 and the second sensor 3432 detect an object at the docking position 303. That is, when both the first sensor 3431 and the second sensor 3432 detect an object at the docking position 303, it indicates that the second container 302 on the transport robot corresponds precisely to the picking port 322, suggesting that picking may be in progress. The third detection component 342 can be shut down to prevent the target item being picked from being detected as a worker's arm, thereby reducing the possibility of false alarms.
[0181] In some examples, if at least one of the first sensor 3431 and the second sensor 3432 fails to detect an object at the docking position 303, the control system can activate the third detection component 342. That is, when the first sensor 3431 and / or the second sensor 3432 fails to detect an object at the docking position 303, it indicates that a portion of the transport robot's structure is located at the docking position 303 and the transport robot is showing a tendency to move, or that the transport robot is not at the docking position 303. In this case, the third detection component 342 is activated to prevent workers from being injured by the moving transport robot.
[0182] For example, the fourth detection component 343 may be one or more of a grating, a detection camera, a security lidar, a security ultrasonic radar, a security radio frequency identification detector, or other security detection equipment, and this application does not limit it.
[0183] It should be noted that the specific detection principle of the fourth detection component 343 can be referred to the description of the first detection component 341, and will not be repeated here.
[0184] like Figure 10 As shown, the warehousing system may include a first operating area 304 and a second operating area 305 for transport robots to operate in. The first operating area 304 can be the operating area for a transport robot corresponding to a workstation 300; that is, the first operating area 304 can be the operating area near the target workstation 300 when the transport robot approaches the target workstation 300. The second operating area 305 can be the operating area for transport robots corresponding to other workstations 300 or aisles; that is, the second operating area 305 can be any area in the warehousing system other than the first operating area 304 that is available for transport robots to operate in.
[0185] For example, when safety unit 390 is in the open state, the control system can stop the transport robot located in the first operating area 304 to avoid harm to personnel within workstation 300. Meanwhile, the transport robot in the second operating area 305 can operate normally within that area. Thus, when one workstation 300 malfunctions, other workstations can continue operating normally, thereby reducing the impact of the malfunction on the sorting efficiency of other workstations.
[0186] In some examples, workstation 300 also includes a fifth detection component 344. The fifth detection component 344 is positioned between the first operating area 304 and the second operating area 305, specifically at the boundary between the two areas. When the safety unit 390 is activated, the fifth detection component 344 detects whether an object is moving between the first and second operating areas 304 and 305. This allows workstation 300 to perform sorting control on the transport robot in case of a malfunction, reducing the impact on work efficiency.
[0187] For example, if the fifth detection component 344 detects an object moving between the first operating area 304 and the second operating area 305, on the one hand, it indicates that the transport robot in the first operating area 304 may have failed to execute the stop command and moved into the second operating area 305; on the other hand, it indicates that the transport robot in the second operating area 305 may have failed to execute the command to operate in the second operating area 305 and moved into the first operating area 304. In this case, there may be a situation of chaotic control commands for the transport robots in the warehousing system. The control system can then control all transport robots to stop operating, thereby preventing harm to workers.
[0188] For example, the fifth detection component 344 may be one or more of a grating, a detection camera, a security lidar, a security ultrasonic radar, a security radio frequency identification detector, or other security detection equipment, and this application does not limit it.
[0189] It should be noted that the specific detection principle of the fifth detection component 344 can be referred to the description of the first detection component 341, and will not be repeated here.
[0190] Figure 11 This is a top view of a third type of workstation provided in the embodiments of this application.
[0191] like Figure 11 As shown, the safety fence 391 can enclose the outer perimeter of the sorting station 310, the seeding wall 350, the loading and unloading equipment 360 and the picking equipment 380 to form the workspace of the workstation 300.
[0192] For example, the safety unit 390 can be installed on the safety fence 391, and the safety unit 390 can be installed adjacent to the safety door 392 and outside the workspace. In this way, before an employee needs to enter the workspace of the workstation 300 through the safety door 392, the employee can operate the safety unit 390 from outside the safety door 392 to shut down the relevant equipment and activate the corresponding detection components.
[0193] For example, the opening and closing of the safety door 392 can also be controlled by the safety unit 390. Alternatively, the opening and closing of the safety door 392 can also be controlled by other structures, which are not limited in this embodiment.
[0194] For example, the security door 392 can be a security door controlled by a mechanical lock or a security door controlled by an electromagnetic lock, and is not limited in this embodiment.
[0195] In some examples, the space where the seeding wall 350 and the picking device 380 are located can be connected, so that workers can pass through this connecting passage (e.g., Figure 11 (As shown by the dashed arrow in the image) Enter the space where the seeding wall 350 and the loading and unloading equipment 360 are located, so that it is convenient to inspect and maintain the loading and unloading equipment 360 and the seeding wall 350.
[0196] Figure 12 This is a top view of the fourth type of workstation provided in the embodiments of this application.
[0197] like Figure 12 As shown, in some examples, the workspace includes a first space 306 and a second space 307, which are separated by a sorting station 310. In this case, the sorting station 310 is located in the first space 306, while the seeding wall 350 and loading / unloading equipment 360 are located in the second space 307. This eliminates the need for connecting passageways within the workspace, thereby reducing the space occupied by a single workstation 300 and facilitating the setup of other workstations 300 or structures within the warehousing system.
[0198] For example, safety door 392 may include a first safety door 3921 and a second safety door 3922. The first safety door 3921 is located at the position of safety fence 391 corresponding to the first space 306, and the second safety door 3922 is located at the position of safety fence 391 corresponding to the second space 307. Thus, personnel can enter and exit the first space 306 through the first safety door 3921 to inspect and maintain the equipment located within the first space 306. Simultaneously, personnel can enter and exit the second space 307 through the second safety door 3922 to inspect and maintain the equipment located within the second space 307.
[0199] It should be noted that, upon considering the specification and practicing the application disclosed herein, those skilled in the art will readily conceive of other embodiments of this application. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
