[0018] In current warehousing systems, some robots transport cartons to pickers, eliminating the need for personnel to move around the warehouse and improving picking efficiency. However, current robots are relatively low, often requiring pickers to bend over, which not only reduces picking efficiency but may also cause injury to operators over time. This specification provides a picking workstation and warehousing system to solve these technical problems.
[0019] like Figure 1 As shown, this application provides a picking workstation, including a base 10, a support assembly 20, and a power assembly 30. The base 10 can be connected to the ground to fix the picking workstation as a whole. The support assembly 20 includes a transmission member 21 and a support member 22. The transmission member 21 is movably mounted to the base 10. The support member 22 is fixed to the transmission member 21. The support member 22 is used to support the toy box.
[0020] The power unit 30 drives the transmission component 21 to move relative to the base 10. Since the support component 22 is fixed to the transmission component 21, it moves with the transmission component 21 to transport cartons containing goods to the pickers for picking, or to remove cartons after picking from the pickers. Driven by the transmission component 21, the support component 22 can generate a displacement at least opposite to the direction of gravity G.
[0021] This manual describes how the power assembly 30 drives the transmission component 21, enabling the support component 22 to generate a displacement opposite to the direction of gravity G, thereby raising the material box. This ergonomic design eliminates the need for pickers to bend over, thus improving the picking efficiency of the picking station.
[0022] In one embodiment, the base 10 is provided with an annular groove 100. The axial direction of the annular groove 100 is taken as a first direction X, which is perpendicular to the gravity direction G. Multiple support components 20 are provided, spaced apart along the annular groove 100.
[0023] By setting the annular groove 100, multiple support members 22 can move along the shape of the annular groove 100 on the base 10. During the movement, different support members 22 can perform different functions, such as placing, picking, or retrieving goods. This eliminates the need for multiple workstations, achieving functional integration, improving the integration level of the picking workstation, and reducing its footprint. Based on this, the flexibility of the picking workstation is also improved. On the one hand, the picking workstation in this specification is lightweight, facilitating transport between different work scenarios. On the other hand, the picking workstation in this specification can also meet the corresponding operational requirements for changes in work scenarios with different volumes.
[0024] In other embodiments, the way the transmission component 21 and the base 10 are movably mounted is not limited, as long as they can generate relative movement. For example, a lead screw mechanism, gear mechanism, or linkage mechanism can be formed between the transmission component 21 and the power component 30, so that the transmission component 21 drives the support component 22 to produce a displacement opposite to the direction of gravity G.
[0025] In embodiments where the base 10 is provided with an annular groove 100, the distribution spacing of the multiple support components 20 can be equal. By equidistantly arranging the support components 20, the spacing between workstations performing different operations is equal, and multiple steps in placing, picking, or retrieving goods can be performed simultaneously, thereby improving the operational efficiency of the picking workstation.
[0026] For example: In one embodiment, please refer to [the document / reference]. Figure 3 As shown, the annular groove 100 is rectangular. There are four supporting components 20. The base 10 is equipped with a loading station 401, a picking station 402, a retrieval station 403, and an idle station 404. Loading, picking, and retrieval can be performed simultaneously, significantly improving the picking efficiency of the picking station. Please refer to the following: Figure 4 and Figure 5 As shown, in this embodiment, during the picking process, three bins 40 are typically placed on the picking station, and the direction of movement of the bins is visible. Figure 5 As indicated by the dashed arrow.
[0027] The three bins 40 include a first bin 41, a second bin 42, and a third bin 43. The goods in the first bin 41 are unpicked. The goods in the second bin 42 are being picked. The goods in the third bin 43 have been picked. After one round of picking, multiple support assemblies 20 move along... Figure 5 Rotate clockwise in the indicated direction to switch the working positions of the first material box 41, the second material box 42 and the third material box 43.
[0028] Specifically, the first material box 41 along Figure 5 The goods are moved clockwise from the indicated location to the picking station 402, transporting unpicked goods to the operator. The second bin 42 also moves clockwise along this path. Figure 5 The robot moves clockwise from picking station 402 to pickup station 403, transporting the picked bins 40 to the pickup robot. After the third bin 43 is taken by the robot, the support component 20 at pickup station 403 moves to idle station 404. The support component 20 at the previously idle station 404 moves to placement station 401 for the robot to place the goods to be picked.
[0029] During this process, after placing the goods to be picked at the delivery station 401, the robot can directly move towards... Figure 5 The robot moves to the right of the indicated position. During the robot's movement, the picking operation is performed simultaneously. After one round of picking is completed, the bin 40 at picking station 402 moves clockwise to pickup station 403. At this time, the robot can simultaneously move to pickup station 403 and directly retrieve the picked bin 40 from pickup station 403, further improving the picking efficiency of picking workstation 1.
[0030] In other embodiments, the number of support components 20 is not limited. For example, there may be two support components 20, each moving vertically. During operation, one support component 20 is positioned below to place unpicked goods onto the robot, while the other support component 20 is positioned above to allow the operator to pick the goods. After one round of picking is completed, the robot retrieves the goods from the picking station, with the upper support component 20 moving downwards and the lower support component 20 moving upwards. Alternatively, there may be three support components 20, which move along a circular or equilateral triangular trajectory.
[0031] In an embodiment where the annular groove 100 is rectangular and the number of supporting components 20 is four, the long side of the annular groove 100 can be perpendicular to the direction of gravity G. That is, when the picking station is fixed to the ground, the long side of the annular groove 100 is parallel to the ground. On the one hand, because the robot is relatively low, in this configuration, the heights of the placement station 401 and the picking station 403 can be adapted to the height of the robot, improving operational efficiency. On the other hand, the picking station occupies less space in the direction of gravity, further improving the integration and flexibility of the picking station.
[0032] In one embodiment, the base 10 may include a rear substrate 11. The annular groove 100 includes a first annular groove 101 disposed on the rear substrate 11. Please refer to [further details omitted]. Figure 6 As shown, the transmission component 21 includes a transmission body 211 and a first shaft 212. The transmission body 211 is used to fix the support component 22. The first shaft 212 protrudes from the transmission body 211 toward the first annular groove 101 and is slidably mounted with the first annular groove 101. The relative sliding between the transmission component 21 and the base 10 is achieved by using a hole-shaft fit. The first annular groove 101 can limit the first shaft 212 perpendicular to the sliding direction, thereby improving the operational stability of the transmission component 21.
[0033] In this embodiment, the base 10 may further include a front substrate 12, and a rear substrate 11 is disposed opposite to the front substrate 12 in the first direction X. The annular groove 100 also includes a second annular groove 102 disposed on the front substrate 12. The transmission member 21 also includes a second shaft 213, which protrudes from the transmission body 211 toward the second annular groove 102 and is slidably mounted to the second annular groove 102. The first shaft 212 and the second shaft 213 extend from the transmission body 211 toward both sides along the first direction X, respectively, and both sides of the transmission member 21 are supported, thereby further improving the operational stability.
[0034] like Figure 1 and Figure 2As shown, the rear substrate 11 is provided with a rear annular protrusion 111, and a first annular groove 101 is provided in the rear annular protrusion 111. The front substrate 12 includes an outer side plate 121 and an inner side plate 122. The outer side plate 121 is annular, and the inner side plate 122 is provided in the hollow portion of the outer side plate 121. The outer side plate 121 is provided with an outer annular protrusion 123. The inner side plate 122 is provided with an inner annular protrusion 124. A second annular groove 102 is formed between the outer annular protrusion 123 and the inner annular protrusion 124.
[0035] In one embodiment, one side of the support assembly 20 is slidably mounted to the base 10 in a first direction X perpendicular to the direction of gravity G. The transmission component 21 and the support component 22 are mounted front and rear in the first direction. Since only one side of the support assembly 20 is slidably mounted to the base 10, the other side of the support assembly 20 is suspended and does not require connection of additional components, further reducing the volume occupied by the picking workstation.
[0036] In one embodiment, a support frame 13 is provided on the side of the base 10 away from the support assembly 20. The support frame 13 has fixing holes 130, the axis of which is parallel to the direction of gravity G. Since the support assembly 20 is connected to the base 10 on only one side, the force exerted by the support assembly 20 on the base 10 is concentrated on one side. By providing a support frame 13 on the side of the base 10 away from the support assembly 20 and fixing the support frame 13 with fixing holes 130, the force exerted by the support assembly 20 on the base 10 can be balanced, improving the stability of the picking station. The support frame 13 may include a base plate 131 and a support rod 132. The fixing holes 130 are provided in the base plate 131. The support rod 132 connects the base plate 131 and the rear base plate 11 to form a triangular support.
[0037] In one embodiment, the rear substrate 11 and the front substrate 12 are connected by a connecting post 14. The rear substrate 11 may be provided with a rear fixing slot 112. The front substrate 12 may be provided with a front fixing slot (not shown). The two ends of the connecting post 14 are respectively inserted into the rear fixing slot 112 and the front fixing slot.
[0038] In one embodiment, in the first direction X, the projection of the first annular groove 101 and the projection of the second annular groove 102 are at least partially offset. Please refer to [further details omitted]. Figure 6 As shown, the first shaft 212 and the second shaft 213 are also offset in the first direction X. That is, when viewed from the first direction X, the projection of the first annular groove 101 and the second annular groove 102 are not completely aligned.
[0039] If the first shaft 212 or the second shaft 213 needs to rotate, the first shaft 212 is limited by the first annular groove 101, and the second shaft 213 is limited by the second annular groove 102. Therefore, they can only rotate around their respective axes. Because the axes of the first shaft 212 and the second shaft 213 are misaligned, when one of them tends to rotate, the other will be limited by the groove structure. This ensures that the transmission component 21 as a whole remains horizontal, thereby ensuring that the support component 22 fixed to the transmission component 21 and the hopper placed on the support component 22 remain horizontal, improving the stability of the picking station.
[0040] Specifically, the projections of the first annular groove 101 and the second annular groove 102 can be offset in the gravitational direction G. In the first direction X, the projections of the first annular groove 101 and the second annular groove 102 have the same width, but the projection of the first annular groove 101 is lower than the projection of the second annular groove 102 in the gravitational direction G. The direction in which the projections of the first annular groove 101 and the second annular groove 102 are offset is not limited.
[0041] Please refer to the following: Figure 7 As shown, the transmission body 211 may include a first part 2111, a second part 2112, and an intermediate part 2113. The intermediate part 2113 connects the first part 2111 and the second part 2112. A first shaft 212 is disposed in the first part 2111. A second shaft 213 is disposed in the second part 2112. The first shaft 212 includes a cylindrical part 2121 and a semi-circular part 2122. The semi-circular part 2122 is used to connect to the support member 22, and the semi-circular hole-shaft fit is used to achieve limiting, so that the part placed on the support member 22 remains horizontal, further improving the stability of the picking station. The cylindrical part 2121 is fitted with a wear-resistant part 2123, which may be a rolling bearing, etc., and contacts the second annular groove 102.
[0042] In one embodiment, please refer to the following: Figure 8 As shown, the transmission body 211 is provided with guide rollers 214, the axis of which is perpendicular to the first direction X and the gravity direction G. When the support member 22 moves parallel to the gravity direction G, the guide rollers 214 abut against the rear substrate 11 and the front substrate 12 on both sides in the first direction X.
[0043] When the support member 22 moves perpendicular to the direction of gravity G, the annular groove 100 provides a supporting force to the transmission member 21 opposite to the direction of gravity G, thereby supporting the weight of the transmission member 21 and improving its operational stability. When the support member 22 moves parallel to the direction of gravity G, the annular groove 100 only provides a limit to the transmission member 21 in the direction perpendicular to gravity G. At this time, by providing guide rollers 214, the movement of the transmission member 21 parallel to the direction of gravity G can be guided to ensure the overall operational stability of the transmission member 21.
[0044] like Figure 1 and Figure 8 As shown, the support member 22 can be integrally plate-shaped, including a support base plate 221, limiting side plates 222, and guide plates 223. The limiting side plates 222 protrude from the support base plate 221 in the opposite direction of gravity G. There are three limiting side plates 222 to form a three-sided enclosure and limitation for the material box. The limiting side plates 222 form a loading / unloading opening 220 on the side away from the base 10, where the guide plates 223 are inclined downwards to facilitate the robot placing the material box on the support base plate 221.
[0045] like Figure 2 , Figure 8 and Figure 9 As shown, the power assembly 30 may include a chain 31 and multiple sprockets 32. The shape of the chain 31 is adapted to the shape of the annular groove 100. The inner side of the chain 31 is drivenly connected to the sprockets 32. The outer side of the chain 31 is rotatably connected to the transmission body 211. The sprocket and chain mechanism has high transmission stability, thereby improving the overall operational stability of the picking station. In an embodiment where the annular groove 100 is rectangular, the chain 31 may be rectangular, and the number of sprockets 32 may be four. The four sprockets 32 are distributed at the four corners of the inner side of the rectangular chain 31, one of which is the driving sprocket and the other three are driven sprockets.
[0046] In one embodiment, the size of the middle portion 2113 is smaller than that of the first portion 2111 and the second portion 2112 in the direction of gravity G. A lug 311 is provided on the outer side of the chain 31, extending between the first portion 2111 and the second portion 2112 and rotatably connected to the middle portion 2113. By setting the size of the middle portion 2113 to be smaller than that of the first portion 2111 and the second portion 2112, a certain clearance space is provided between the first portion 2111 and the second portion 2112. Placing the lug 311 within this clearance space improves structural compactness and further reduces the space occupied by the picking station.
[0047] This specification also provides a warehousing system, including the aforementioned picking station. Because the picking station in this specification has high picking efficiency, the warehousing system described herein has high operational efficiency.
