As shown in fig. 1 to 4, the embodiment of the present application provides a workstation 1, the workstation 1 including a sorting mechanism 3 and a buffer mechanism 2. Wherein the sorting mechanism 3 comprises a raw material box conveying line 4 and an order box conveying line 5. The raw material bin conveyor line 4 is configured to convey raw material bins for storing goods to be sorted. The order box transfer line 5 is configured to transfer order boxes for receiving goods sorted out from the stock boxes. The caching mechanism 2 is used for caching order boxes of incomplete picking tasks.

It will be appreciated that the tote conveyor line 4 has at least one pick-up location 40 and that the order tote conveyor line 5 has at least one delivery location 50, and that upon arrival of the tote at the pick-up location 40, the tote to be sorted within the tote is picked up and placed in the order tote at the delivery location 50.

In some embodiments, the buffer mechanism 2 is located laterally of the sorting mechanism 3 and delivers the order boxes to the delivery location 50 in a delivery order, which may be determined by the order in which the raw material boxes reach the pick-up location 40.

It should be noted that, after completing a sorting operation, the sorting mechanism 3 may switch the raw material boxes and the order boxes, and according to the allocated order tasks, there is a corresponding mapping relationship between the raw material boxes and the order boxes, and according to the order in which the raw material boxes reach the goods taking place 40, the corresponding order boxes may form a corresponding conveying order, so that the raw material boxes and the order boxes that are mapped mutually reach the goods taking place 40 and the delivery place 50 synchronously.

In the workstation 1 provided in this embodiment, after completing order picking, the order box will determine its next flow direction according to the specific situation, if all the order tasks corresponding to the order box have been picked, the order box may be output from the sorting mechanism 3, and if all the order tasks corresponding to the order box have not been picked, the order box may be transported to the buffer mechanism 2 for temporary storage, and the delivery position 50 may be switched to the next order box for sorting operation, without waiting for the order box that has not been picked up on the delivery position 50, thereby improving the overall logistics efficiency of the workstation 1.

In some embodiments, the caching mechanism 2 may include at least one of a stereoscopic storage mechanism 10 and a planar storage mechanism 20. For example, as shown in fig. 5 to 7, the caching mechanism 2 may include only the planar storage mechanism 20. Alternatively, as shown in fig. 8 to 10, the buffer mechanism 2 may include only the stereoscopic storage mechanism 10. Alternatively, as shown in fig. 2 to 4, the buffer mechanism 2 may include a stereoscopic storage mechanism 10 and a planar storage mechanism 20, which is not particularly limited in the embodiment of the present application.

The manner of setting the three-dimensional storage mechanism 10 will be described in detail below.

With continued reference to fig. 1-4, and fig. 23 and 24, the stereoscopic storage mechanism 10 may include a shelf including a storage layer 11 and a transport layer 12 arranged in a vertical direction. The storage layer 11 is used for temporarily storing the order boxes with incomplete picking tasks, and the conveying layer 12 is in butt joint with the order box conveying line 5.

It will be appreciated that in order box transfer lines 5, when an order box at delivery station 50 has not completed a picking order requiring temporary storage, the order box may be transferred to transfer layer 12, followed by transfer layer 12 to storage layer 11 for temporary storage.

Illustratively, the transport layer 12 has a warehouse entry port that interfaces upstream of the order box transport line 5 and a warehouse exit port that interfaces downstream of the order box transport line 5. When the order boxes with incomplete picking tasks are transferred to the downstream along the order box conveying line 5, the order boxes can enter the three-dimensional storage mechanism 10 through the warehouse entry port to be conveyed to the layer 12 and then be conveyed to the storage layer 11 by the conveying layer 12, and when the temporarily stored order boxes are required to be picked again, the target order boxes can be taken out from the storage layer 11, firstly conveyed to the conveying layer 12 and then conveyed to the upstream of the order box conveying line 5 through the warehouse exit port of the output layer 12, and the order boxes can flow to the delivery position 50 along the order box conveying line 5, so that the picking operation can be continued.

The transfer mechanisms are disposed at both ends of the order box transfer line 5 along the conveying direction, and the transfer mechanisms at both ends of the order box transfer line 5 are respectively opposite to the warehouse entry port and the warehouse exit port. The transfer mechanism may move the order boxes from the out-warehouse port of the transport layer 12 to the order box transfer line 5, or the transfer mechanism may move the order boxes from the order box transfer line 5 to the in-warehouse port of the transport layer 12.

Illustratively, the transfer mechanism may include one or more conveying structures such as a conveying roller, a conveying belt, and the like, and is driven by a motor, and the specific transmission form adopted by the transfer mechanism is not limited in the embodiment of the present application.

The manner in which the planar storage mechanism 20 is provided will be described in detail below.

With continued reference to fig. 1-4, in some embodiments, the flat storage facility 20 may include a candidate aisle 21 and the order box transfer line 5 may include a pick aisle 51 with the candidate aisle 21 being located laterally of the pick aisle 51 and the delivery locations 50 being disposed on the pick aisle 51.

Wherein candidate aisle 21 is used to place candidate order boxes for transfer to picking aisle 51 in the order of delivery. The candidate order boxes may include order boxes delivered directly from the delivery station 50 to the candidate aisle 21 or order boxes delivered from the stereoscopic storage mechanism 10 to the candidate aisle 21.

It will be appreciated that when the order box with the unfinished picking task is temporarily stored, the time of the next picking of the order box can be determined or estimated according to the specific order task content, if the time interval between the next picking is longer, the order box can be temporarily stored in the three-dimensional storage mechanism 10 with larger storage capacity, and when the order box is next picked, the order box can be taken out from the three-dimensional storage mechanism 10 and transferred to the candidate channel 21. If the time between picking of the order box is short, the order box can be directly conveyed to the candidate channel 21, so that the conveying time required for entering the delivery position 50 when the order box is picked next time can be shortened, and the logistics efficiency is improved.

It should be noted that, in the workstation 1 provided in this embodiment of the present application, when the three-dimensional storage mechanism 10 and the planar storage mechanism 20 are simultaneously provided, the order box that needs to be temporarily stored can be split, so that the efficiency of logistics is improved while the temporary storage space is fully utilized.

In some embodiments, the candidate aisle 21 and the picking aisle 51 are parallel to each other, and the candidate aisle 21 is provided with a transfer mechanism for transferring candidate order boxes to the picking aisle 51 in a direction perpendicular to the picking aisle 51 so that the candidate order boxes arrive at the delivery station 50 in the order of delivery.

It will be appreciated that the transfer mechanism is used to transfer and transfer order boxes between the candidate aisles 21 and the picking lanes 51, and that when the candidate aisles 21 and the picking lanes 51 are parallel to each other, the transfer mechanism transfers the order boxes in a direction perpendicular to the direction in which the candidate aisles 21 and the picking lanes 51 transfer the order boxes.

Illustratively, the transfer mechanism may include one or more conveying structures such as conveying rollers, conveying belts, etc., and the structure of the transfer mechanism may be the same as or similar to that of the foregoing transfer mechanism, which is not described herein.

In some embodiments, planar storage mechanism 20 may further include a queuing tunnel 22, where queuing tunnel 22 is located between candidate tunnel 21 and pick tunnel 51, where order boxes to be picked in candidate tunnel 21 are configured to pass through queuing tunnel 22 before entering pick tunnel 51.

It will be appreciated that since the order boxes need to be formed in a predetermined delivery sequence as they are delivered from candidate aisle 21 to picking aisle 51, the delivery sequence may be the same or different from the order boxes entering planar storage mechanism 20. Therefore, by setting the queuing channel 22, the order boxes can be regulated in order sequence and queuing position, so that when the order boxes enter the picking channel 51 from the candidate channel 21, a preset conveying sequence can be quickly and accurately formed, and the situation of box clamping or wrong sequencing is avoided.

Illustratively, the candidate aisle 21, the queuing aisle 22 and the picking aisle 51 are parallel to each other, and the candidate aisle 21 is provided with a transfer mechanism for transferring the candidate order boxes in a direction perpendicular to the queuing aisle 22 to queue the candidate order boxes in the queuing aisle 22 in the order of transfer, and sequentially from the queuing aisle 22 to the picking aisle 51.

It should be noted that, the specific structure and arrangement of the transfer mechanism between the candidate aisle 21 and the queuing aisle 22 may be the same as or similar to that between the candidate aisle 21 and the picking aisle 51, and will not be described here again.

Referring to fig. 2 to 4, in some embodiments, the workstation 1 provided in the embodiments of the present application may further include a return line 6, where the return line 6 is located at an end of the candidate aisle 21 and the picking aisle 51, and the return line 6 communicates with the candidate aisle 21 and the picking aisle 51. At least part of the order boxes for which picking tunnel 51 has not completed picking is returned to candidate tunnel 21 via return line 6.

It will be appreciated that an unfinished picked order box at the delivery location 50 will be transported in the direction of conveyance of the order box transport line 5 to the return line 6 and then flow along the return line 6 into the candidate aisle 21.

For example, the return line 6 may be perpendicular to the conveying direction of the candidate aisles 21 and the picking aisles 51.

In some embodiments, the workstation 1 provided by embodiments of the present application may further include an empty bin line 52 and a full bin line 53. Empty bin line 52 is connected to the input of picking tunnel 51 and is configured to deliver empty order bins to picking tunnel 51. Full bin line 53 interfaces with the output of picking lane 51 and is configured to receive a bin of orders picked in picking lane 51.

The empty box line 52 may be docked with a transfer robot, a transfer line, or the like, external to the workstation 1, to receive empty order boxes. The full box line 53 may also interface with a transfer robot, conveyor line, or the like, external to the workstation 1 to transfer the picked order boxes to the outside for a next logistics process, such as packaging, or the like. The specific extension length and arrangement orientation of the empty tank line 52 and the full tank line 53 may be set according to the actual layout of the workstation 1, which is not particularly limited in the embodiment of the present application.

Fig. 11 is a schematic structural diagram of a raw material box conveying line in a workstation according to an embodiment of the present application, and fig. 12 is a schematic structural diagram of a raw material box conveying line in a workstation according to an embodiment of the present application.

Referring to fig. 2-12, in some embodiments, the order box conveyor line 5 and the tote conveyor line 4 are both U-shaped and at least partially disposed around the caching mechanism 2. Thus, the space utilization of the workstation 1 can be improved, and the space occupation rate of the order box conveying line 5, the raw material box conveying line 4 and the three-dimensional storage structure can be reduced.

Wherein, when order case is carried along different directions on order case transfer chain 5, the different sides of order case are towards order case transfer chain 5's direction of conveyance. When the raw material box is conveyed on the raw material box conveying line 4 along different directions, different sides of the raw material box face the conveying direction of the raw material box conveying line 4.

Illustratively, the direction of conveyance of the order box conveyor line 5 is parallel to the direction of conveyance of the headbox conveyor line 4. Order case transfer chain 5 and raw materials case transfer chain 4 can be in the layering setting in vertical direction, reduce vertical projected area to improve space utilization.

The sorting mechanism 3 is provided with a sorting station 30 on the side facing away from the buffer mechanism 2. The sorting station 30 may be manually operated or a sorting robot may be provided to perform the sorting operation, as in the embodiments of the present application not specifically limited.

The specific structure of the sorting mechanism 3 is exemplarily described below.

Referring to fig. 14-16, in some embodiments, the tote conveyor lines 4 and the order tote conveyor lines 5 are spaced apart in a vertical direction, with the tote conveyor lines 4 being above the order tote conveyor lines 5.

Wherein, raw materials case transfer chain 4 and order case transfer chain 5 dislocation set in the horizontal direction to make the projection of order case in the vertical direction at least partially not coincide for the projection of raw materials case in the vertical direction. The distance from the sorting station 30 to the side of the raw material box transfer line 4 near the sorting station 30 is greater than the distance from the sorting station 30 to the side of the order box transfer line 5 near the sorting station 30.

It will be appreciated that the order box conveyor line 5 is not obscured in the vertical direction by the tote conveyor line 4 when the sorting personnel or the sorting robot at the sorting station 30 is performing a sorting operation, thereby improving the convenience of the sorting operation.

In some embodiments, the feedbox conveyor line 4 has a feedbox inlet 45 and a feedbox outlet 46, the feedbox inlet 45 and the feedbox outlet 46 being located at respective ends of the feedbox conveyor line 4. As shown in fig. 12, the workstation 1 may further include a reflow mechanism 41, both ends of the reflow mechanism 41 being respectively docked with the raw tank inlet 45 and the raw tank outlet 46.

Wherein, to the raw materials case that accomplishes the letter sorting task, still remain the goods in the raw materials case to corresponding goods corresponds the order task of other order casees that follow next, can be through the back flow mechanism 41 with this raw materials case follow raw materials case export 46 back to raw materials case entry 45, like this, this raw materials case can get back to goods position 40 again along raw materials case transfer chain 4, need not to send this raw materials case back to outside storage device, and then reduced the circulation path of this raw materials case, improved logistics efficiency.

Illustratively, a return sequencing area 42 is provided laterally of the raw material tank inlet 45, the return sequencing area 42 being provided with raw material tank temporary storage locations for adjusting the feed sequence of the raw material tanks. Therefore, the conveying sequence of the corresponding raw material boxes can be adjusted according to the conveying sequence of the formed order boxes, the condition that the raw material boxes are blocked and blocked is avoided, and the smoothness of raw material box circulation is improved.

In some embodiments, the tote conveyor line 4 and the order box conveyor line 5 extend in the same direction, with the sorting station 30 being located laterally of the sorting mechanism 3 opposite the pick-up station 40 and the delivery station 50.

Wherein the bin transfer line 4 is inclined with respect to the horizontal direction towards the sorting station 30. Because the raw material box conveying line 4 is located above the order box conveying line 5, and the distance between the raw material box conveying line 4 and the sorting position 30 is further, the raw material box on the raw material box conveying line 4 which is obliquely arranged can slide to a side close to the sorting position 30 by a certain distance by means of gravity. In this way, the sorting personnel or sorting robot at the sorting station 30 is facilitated to take out the goods from the stock bin.

In some embodiments, the sorting mechanism 3 may also include a plurality of support columns 31 with the order box transfer lines 5 connected between adjacent support columns 31. The raw material box conveying line 4 is positioned at the top of the supporting column 31 and is detachably connected with the supporting column 31.

Illustratively, the support columns 31 may be supported on the peripheral sides of the tote conveyor line 4 and the order box conveyor line 5. Wherein one or more support columns 31 may be provided at the end corner positions of the raw material box conveyor line 4 and the order box conveyor line 5, and at the side edge positions in the length direction, respectively.

The material of the support column 31 may be metal or alloy such as iron or aluminum, or engineering plastic with high structural strength, for example, the support column 31 may be a section bar made of aluminum alloy. Both the raw material box transfer line 4 and the order box transfer line 5 can be connected to the support column 31 by fasteners such as bolts and connecting members such as a tripod. The specific material type of the support column 31 is not limited in the embodiment of the present application.

Referring to fig. 17-22, in some embodiments, the sorting mechanism 3 may further include an adjustment member 32. The adjusting member 32 is connected to the support column 31, the raw bin transfer line 4 is connected to the adjusting member 32, and the adjusting member 32 is configured to adjust the position of the raw bin transfer line 4 relative to the order bin transfer line 5.

Wherein, be equipped with first connecting hole 33 on the regulating part 32, be equipped with a plurality of second connecting holes 34 of arranging along its width direction on the raw materials case transfer chain 4, when first connecting hole 33 and different second connecting holes 34 are relative, raw materials case transfer chain 4 is located different positions for order case transfer chain 5. The sorting mechanism 3 may further comprise a fastener passing through the first connection hole 33 and screwed with the second connection hole 34.

It will be appreciated that the first attachment hole 33 may be adjusted to oppose a different second attachment hole 34 on the tote conveyor line 4 by removing fasteners in different applications, thereby adjusting the relative position of the vertical projection of the tote conveyor line 4 to the vertical projection of the order tote conveyor line 5, i.e., the size of the portion of the order tote that is not obscured by the tote in the vertical direction may be adjusted. For example, if the items to be picked are of a larger size, the tote conveyor line 4 is moved away from the sort station 30 to provide a larger size of the unoccluded portion of the order box on the order box conveyor line 5 to allow sufficient space for placing the items in the order box. If the size of the goods to be picked is small, the bin conveyor line 4 is moved in a direction approaching the sorting station 30 so that the size of the unoccluded portion of the order bin conveyor line 5 is reduced, whereby the floor space of the workstation can be reduced.

In some embodiments, as shown in fig. 17-20, the tote conveyor line 4 may include a first conveyor 43, with the first conveyor 43 having a first baffle 44 at an end toward the sort station 30, and the first baffle 44 spaced from an end of the first conveyor 43. The order box transfer line 5 may include a second transfer member 54, with a second baffle 55 disposed at an end of the second transfer member 54 facing the sorting station 30, with the second baffle 55 spaced from an end of the second transfer member 54.

When the raw material box is located on the raw material box conveyor line 4, the raw material box is at least partially located outside the side of the first conveyor 43 close to the sorting station 30 and abuts against the first baffle 44. When the order box is located on the order box transfer line 5, the order box is at least partially located outside the side of the second transfer member 54 adjacent the sorting station 30 and abuts the second stop 55.

It will be appreciated that the first baffle 44 is located on the side of the tote conveyor line 4 closer to the sort station 30 and the second baffle 55 is located on the side of the order tote conveyor line 5 closer to the sort station 30, so that both the totes at the pick-up station 40 and the order totes at the delivery station 50 can be located closer to the sort station 30, thereby improving the convenience of the sorting operation.

For example, the distance between the first baffle 44 and the end of the first conveying member 43 facing the sorting position 30 may be 40mm or more and 50mm or less. For example, specific values of the distance of the first baffle 44 from the end of the first conveying member 43 toward the sorting station 30 may include, but are not limited to, 5mm, 10mm, 20mm, 30mm, 40mm, 41mm, 45mm, 49mm, 50mm, 60mm, 70mm, etc., which are not specifically limited in this embodiment.

Illustratively, the distance between the second baffle 55 and the end of the second conveying member 54 facing the sorting station 30 is greater than or equal to 40mm and less than or equal to 50mm. For example, specific values of the distance of the second baffle 55 from the end of the second conveyor 54 toward the sorting station 30 may include, but are not limited to, 5mm, 10mm, 20mm, 30mm, 40mm, 41mm, 45mm, 49mm, 50mm, 60mm, 70mm, etc., as the embodiments of the present application are not specifically limited thereto.

With continued reference to fig. 14-16, in some embodiments, the sorting mechanism 3 may further include a detection mechanism 7, the detection mechanism 7 being configured to detect the sorting status of the goods at the pick-up location 40 and the delivery location 50 to cause the pick-up location 40 to switch stock boxes or the delivery location 50 to switch order boxes.

It will be appreciated that the detection mechanism 7 may detect whether the goods in the stock box have been removed and whether there are goods placed in the order box. When it is detected that the goods in the stock box of the goods taking place 40 have been taken out, the goods taking place 40 can automatically perform the box cutting operation, and switch to the next stock box. When it is detected that goods are placed in the order boxes of the delivery station 50, the delivery station 50 can automatically perform a box-cutting operation and switch to the next order box. In this way, the logistic efficiency of the sorting mechanism 3 can be improved.

For example, the detection mechanism 7 may comprise a first weighing unit 71, the first weighing unit 71 being arranged at the picking position 40, the first weighing unit 71 being configured to detect weight information of the raw material boxes on the picking position 40, such that the picking position 40 switches the raw material boxes according to the weight information of the raw material boxes.

For example, the detection mechanism 7 may comprise a second weighing unit 72, the second weighing unit 72 being arranged at the delivery location 50, the second weighing unit 72 being configured to detect weight information of the order boxes on the delivery location 50, such that the delivery location 50 switches order boxes according to the weight information of the order boxes.

The detection mechanism 7 may comprise, for example, a first grating unit 73, the first grating unit 73 being arranged above the picking position 40 to form a detection area above the raw material tank of the picking position 40, the first grating unit 73 being configured to detect a cargo retrieval action of the raw material tank on the picking position 40 to cause the picking position 40 to switch the raw material tank after the cargo of the raw material tank has been retrieved.

For example, the detection mechanism 7 may comprise a second grating unit 74, the second grating unit 74 being arranged above the delivery location 50 to form a detection area above the order boxes of the delivery location 50, the second grating unit 74 being configured to detect a goods placement action of the order boxes on the delivery location 50 to cause the delivery location 50 to switch the order boxes after the goods are placed into the order boxes.

The first weighing unit 71 and the second weighing unit 72 may be pressure sensors or electronic scales having pressure sensors as main components. The first grating unit 73 and the second grating unit 74 may be infrared sensors or laser sensors, etc. The pickup place 40 may be provided with any one of the first weighing unit 71 and the first grating unit 73, or the pickup place 40 may be provided with the first weighing unit 71 and the first grating unit 73 at the same time to improve the accuracy of the detection result. The delivery station 50 may be provided with either the second weighing unit 72 or the second grating unit 74, or the delivery station 50 may be provided with both the second weighing unit 72 and the second grating unit 74 to increase the accuracy of the detection result. The embodiment of the present application is not particularly limited thereto.

With continued reference to fig. 14-16, in some embodiments, the side of the sorting mechanism 3 facing the sorting station 30 is provided with a cut box button 8, the cut box button 8 being configured to control the tote conveyor line 4 to switch the totes of the pick-up station 40 and/or to control the order box conveyor line 5 to switch the order boxes of the delivery station 50.

It will be appreciated that when the sorting station 30 is manually operated for sorting, after completing the sorting operation of the goods, the sorting personnel may perform the box-cutting operation by pressing the box-cutting button 8.

Illustratively, the cut box button 8 is located at the bottom of the sorting mechanism 3 so that the sorting personnel can press the cut box button 8 by foot. Alternatively, the cut box button 8 is located laterally of the sorting mechanism 3 so that the sorting person can press the cut box button 8 through the knee. Thus, the operator does not need to press the oblique cutting button by hand, so that the sorting operation of the operator by hand cannot be interfered, and the sorting efficiency is improved. For example, when the picker takes out the goods from the stock box, the goods can be put into the order box by hand while the stock box is cut by pressing the box cutting button 8 with the foot or knee. When the sorting personnel put the goods into the order box, the sorting personnel can take out the goods in the raw material box by hand while pushing the box cutting button 8 by feet or knees to cut the order box.

In some embodiments, the tote continues to move in the transport direction of the tote conveyor line 4 as it passes the pick site 40, thereby improving the transfer efficiency of the tote by removing the cargo from the tote by the operator of the sort site 30 during the tote pass through the pick site 40. When the order box passes through the delivery position 50, the order box continuously moves along the conveying direction of the order box conveying line 5, so that an operator of the sorting position 30 places goods into the order box in the process that the order box passes through the delivery position 50, and the circulation efficiency of the order box is improved.

It will be appreciated that the respective stock and order boxes may be synchronized through the pick-up location 40 and delivery location 50, respectively, while in circulation, or the order boxes may be slightly later than the stock boxes as a result of the pick operation prior to the put operation. The conveying speed of the raw material box along the raw material box conveying line 4 and the conveying speed of the order box along the order box conveying line 5 are not particularly limited, and only the operator or the manipulator at the sorting position 30 can finish the sorting operation in the time of passing through the goods taking position 40 and the delivery position 50.

It should be noted that the sorting station 30 has a sorting operating range that covers the pick-up station 40 and the delivery station 50. When the goods in the raw material box are not sorted to the order box and either of the raw material box and the order box exceeds the sorting operation range, the raw material box conveying line 4 stops conveying the raw material box and the order box conveying line 5 stops conveying the order box. For example, when there are multiple items in one stock bin at the pick-up location 40 that need to be simultaneously picked up and placed in an order bin at the delivery location 50, the sorting operation may not be performed for sufficient time at the sorting location 30, and the stock bin conveyor line 4 and the order bin conveyor line 5 may be suspended at this time so that the operator or robotic arm at the sorting location may complete the respective sorting operations. After the sorting operation is completed, the tote conveyor line 4 and the order tote conveyor line 5 may be started.

It should be noted that, the sorting mechanism that this application embodiment provided is through structural design and relative position's the overall arrangement to order case transfer chain and raw materials case transfer chain, when guaranteeing that the goods of raw materials case letter sorting to order case's process is smooth and easy not blockked, has shortened path and the flow that the goods need be transported in the letter sorting process, has improved the efficiency of goods letter sorting to the accuracy of letter sorting process has been guaranteed.

The specific structure of the stereoscopic storage mechanism will be described in detail below.

Referring to fig. 23 to 27, an embodiment of the present application provides a three-dimensional storage mechanism 10, where the three-dimensional storage mechanism 10 includes a first shelf 100, a second shelf 200, and a lifting device 300. The first shelf 100 and the second shelf 200 are used for storing goods, and the lifting device 300 can pick and place goods on the first shelf 100 or the second shelf 200. The first shelf 100 and the second shelf 200 are spaced apart, and a lifting channel 13 extending in the first direction is provided between the first shelf 100 and the second shelf 200, the lifting device 300 is located in the lifting channel 13, and the lifting device 300 can move along the lifting channel 13.

The first direction may be a vertical direction, the lifting channel 13 extends along the vertical direction, and the lifting device 300 may move up and down along the first direction, that is, the lifting device 300 may move up and down along the height direction of the first shelf 100 and the second shelf 200. The lifting device 300 may be movably connected with at least one of the first and second shelves 100, 200 such that the lifting device 300 climbs along the lifting channel 13 between the first and second shelves 100, 200.

In some embodiments, the first pallet 100 and the second pallet 200 each comprise a plurality of storage levels 11 and at least one transport level 12 arranged along a first direction. The transport layer 12 is configured to receive goods from a side facing away from the hoistway 13 or to transport goods to a side facing away from the hoistway 13.

It will be appreciated that the transport layer 12 may be either of the first pallet 100 and the second pallet 200, and that the side of the transport layer 12 facing away from the hoistway 13 may be the exit or entrance of the cargo. The stereoscopic storage mechanism 10 in the embodiment of the present application may receive the goods transported by the external device through the transport layer 12, or send the goods stored on the first shelf 100 and the second shelf 200 to other external devices through the transport layer 12.

For example, the lifting device 300 may interface with the first pallet 100, and the side of the lifting device 300 facing away from the first pallet 100 may have a slight clearance from the side of the second pallet 200 facing the lifting channel 13; alternatively, the lifting device 300 may interface with the second pallet 200, and the side of the lifting device 300 facing away from the second pallet 200 may have a slight clearance from the side of the first pallet 100 facing the lifting channel 13; alternatively still, opposite sides of the lifting device 300 may interface with the first and second shelves 100, 200, respectively, and the width of the lifting device 300 may match the width of the lifting channel 13.

It should be noted that, in the three-dimensional storage mechanism 10 provided in this embodiment of the present application, by forming the lifting channel 13 between the first shelf 100 and the second shelf 200, the lifting device 300 is utilized to move in the lifting channel 13 to pick and place the goods, and the shelf can directly receive or send out the goods through the conveying layer 12, so that under the condition that the occupied area of the three-dimensional storage mechanism 10 is smaller, the goods in-out efficiency of the three-dimensional storage mechanism 10 is improved, and the lawn effect of the three-dimensional storage mechanism 10 is improved. Of course, more shelves can be provided for the stereoscopic storage mechanism 10, and only the lifting device 300 needs to be provided between two adjacent shelves, which is not limited in the embodiment of the present application, and two shelves will be taken as examples for illustration and not be repeated.

Further, the storage layers 11 of the first pallet 100 and the second pallet 200 may be equal in layer height. The transport layers 12 of the first pallet 100 and the second pallet 200 may be located at the bottom, middle or top, while the transport layers 12 of the first pallet 100 and the second pallet 200 may have the same height in the first direction, e.g., the transport layers 12 on both are located at the bottom of the pallet. Alternatively, the conveying layers 12 of the first pallet 100 and the second pallet 200 may have different heights in the first direction, and only the sides of the conveying layers 12 of the first pallet 100 and the second pallet 200 facing away from the lifting channel 13 may be convenient for docking with external devices, for example, the sides of the conveying layers 12 facing away from the lifting channel 13 may be docking with external conveying lines, or docking with external conveying robots, or the like.

The first direction is defined as the X direction, the first direction is the height direction of the first shelf 100 and the second shelf 200, the second direction is defined as the Y direction, the second direction is the width direction of the elevating channel 13, the third direction is defined as the Z direction, and the third direction is the direction perpendicular to the XY plane.

The specific way and flow of the three-dimensional storage mechanism 10 will be described in detail first.

With continued reference to fig. 23-27, in some embodiments, when the lifting device 300 moves along the lifting channel 13 to be opposite to any storage tier 11, the lifting device 300 may remove the cargo from the storage tier 11 or place the cargo into the storage tier 11. When the lifting device 300 moves along the lifting channel 13 to be opposite to the transport layer 12, the lifting device 300 is configured to send goods into the transport layer 12 or to receive goods of the transport layer 12. In this way, the lifting device 300 can take out the goods in the storage layer 11 and send the goods out of the conveying layer 12, or store the goods in the conveying layer 12 in the storage layer 11, thereby improving the efficiency of the goods in and out.

It will be appreciated that the lifting device 300 may be moved along the lifting path 13 to the storage tier 11 where the target cargo is located and the target cargo removed from the storage tier 11 during the shipment process. Thereafter, the lifting device 300 may be moved along the lifting path 13 to be opposite to the transport layer 12, the transport layer 12 may be the transport layer 12 of the first pallet 100 or the transport layer 12 of the second pallet 200, and the lifting device 300 may place the target cargo onto the transport layer 12. The transport layer 12 may then transfer the target cargo to a side facing away from the lifting channel 13, completing the warehouse-out operation of the stereoscopic storage mechanism 10.

In the warehouse-in process, the upstream cargo may be fed into the transport layer 12 by a device such as a conveyor line or a transfer robot, and the transport layer 12 may be the transport layer 12 of the first pallet 100 or the transport layer 12 of the second pallet 200. Thereafter, the lifting device 300 may be moved along the lifting channel 13 to be opposite to the transport layer 12, and the transport layer 12 may autonomously transfer the goods onto the lifting device 300, or the goods may be taken out of the transport layer 12 by the lifting device 300. Subsequently, the lifting device 300 may be moved along the lifting path 13 to be opposite to the target storage layer 11 and put the goods into the target storage layer 11.

In order to further improve the efficiency of the warehouse-in and warehouse-out, the warehouse-in and warehouse-out processes can be performed simultaneously. The transport layers 12 of the first pallet 100 and the second pallet 200 are positioned at the same height, and when the lifting device 300 is moved to the height position where the transport layers 12 are positioned, both sides of the lifting device 300 are respectively opposite to the transport layers 12 on the first pallet 100 and the second pallet 200.

In some embodiments, the conveyor layer 12 of the first pallet 100 has a first conveyor line 110 and the conveyor layer 12 of the second pallet 200 has a second conveyor line 220, the conveyor directions of the first conveyor line 110 and the second conveyor line 220 being the same. One of the first conveyor line 110 and the second conveyor line 220 is configured to receive cargo from a side facing away from the hoistway 13, and the other of the first conveyor line 110 and the second conveyor line 220 is configured to convey cargo to a side facing away from the hoistway 13.

It is understood that the first conveying line 110 and the second conveying line 220 may be unidirectional conveying lines, one of which is responsible for warehousing, and the other of which is responsible for ex-warehouse, so that the efficiency of goods entering the shelves can be improved by unidirectional conveying of the goods.

Illustratively, the first conveying line 110 and the second conveying line 220 are relatively arranged, and when the lifting device 300 moves between the first conveying line 110 and the second conveying line 220, the first conveying line 110, the second conveying line 220 and the lifting device 300 jointly form the warehouse-in and warehouse-out channel 14, so that the synchronous shipment and the shipment of the warehouse goods can be realized, and the logistics efficiency is improved.

The following description will take, as an example, a first conveyor line 110 being responsible for the shipment and a second conveyor line 220 being responsible for the shipment.

When the in-out and in-out processes are performed simultaneously, the lifting device 300 may take out the goods to be in-out from the storage layer 11, and at the same time, the second conveyor line 220 receives the goods to be in-out sent from the outside and performs in-out waiting in the second conveyor line 220. Thereafter, the lifting device 300 moves along the lifting path 13 to be opposite to the two conveying floors 12, and the second conveying line 220 conveys the goods to be stocked into the lifting device 300 while the lifting device 300 conveys the goods to be stocked into the first conveying line 110. The first transfer line 110 may then send the goods to be taken out to an external device, and at the same time, the lifting device 300 may move along the lifting path 13 and place the goods to be taken in into the target storage layer 11. The above process is repeated, and the stereoscopic storage mechanism 10 can realize synchronous continuous goods input and output operation.

It should be noted that the access channel 14 may extend along the second direction, that is, the access channel 14 extends along the Y direction. The second direction is perpendicular to the first direction, which is the vertical direction, and the access duct 14 extends in the horizontal direction. Through the conveying layer 12, the three-dimensional storage mechanism 10 can put cargoes in and out in the horizontal direction, and the goods shelves are conveniently in butt joint with external conveying lines and other devices.

A specific driving structure of the elevating device 300 moving along the elevating path 13 will be described in detail.

Referring to fig. 28 to 30 in combination with fig. 23 to 27, in some embodiments, the stereoscopic storage mechanism 10 may further include a first driving assembly 400, where the first driving assembly 400 may be disposed on any one of the first shelf 100 and the second shelf 200, and the first driving assembly 400 is configured to drive the lifting device 300 to move along the lifting channel 13, so as to improve the efficiency of the lifting device 300 moving along the lifting channel 13.

It is understood that the first driving assembly 400 may be disposed on the first shelf 100 or the second shelf 200, the shelf on which the first driving assembly 400 is disposed is an active shelf, and the shelf on which the first driving assembly 400 is not disposed is a passive shelf. Alternatively, the first shelf 100 and the second shelf 200 are respectively provided with a first driving assembly 400 for driving the lifting device 300 synchronously, which is not particularly limited in the embodiment of the present application. The first drive assembly 400 is described in detail below as an example of being disposed on the first shelf 100.

In some embodiments, the first drive assembly 400 may include a first drive unit 410, a first flexible transmission 420, and a plurality of first drive wheels 430. The first driving wheels 430 are respectively disposed at two ends of the first shelf 100 along the first direction, the first flexible driving member 420 is wound around the first driving wheels 430, the first driving unit 410 is disposed on the first shelf 100 and configured to drive the first flexible driving member 420 to drive along the first direction, and the lifting device 300 is connected with the first flexible driving member 420, so as to drive the lifting device 300 to perform lifting motion through the first flexible driving member 420.

It will be appreciated that the plurality of first driving wheels 430 may be divided into four groups, each group having at least one first driving wheel 430, and the four groups of first driving wheels 430 may be disposed on the cross beams on both sides of the top of the first pallet 100 and on the cross beams on both sides of the bottom of the first pallet 100, respectively, such that the first flexible driving member 420 may form a closed loop around the first pallet 100 when wound around the plurality of first driving wheels 430. For example, referring to fig. 24, when the first flexible transmission member 420 is transmitted counterclockwise, the elevating device 300 is elevated; when the first flexible transmission member 420 is driven clockwise, the lifting device 300 descends, so that smoothness of movement of the lifting device 300 along the lifting channel 13 can be improved.

In addition, the first driving unit 410 may be disposed at a side of the first shelf 100 facing away from the lifting channel 13, and the plurality of first driving wheels 430 disposed at the top and bottom of the first shelf 100 may be driven wheels, and an output end of the first driving unit 410 may be connected with a driving wheel, and the first driving unit 410 may power transmission of the first flexible transmission member 420 through the driving wheel. The first driving unit 410 is disposed at a side facing away from the lifting channel 13, so that the first driving unit 410 can be prevented from occupying the space in the lifting channel 13, so that the lifting device 300 can fully utilize the space in the lifting channel 13, and the lawn effect of the stereoscopic storage mechanism 10 is improved.

The first driving unit 410 may be a motor, an output end of the motor may be provided with a speed reducer, the first flexible transmission member 420 may be a flexible component such as a belt, a synchronous belt, a wire rope, a chain, and the like, and the first driving wheel 430 may be a driving wheel such as a belt pulley, a synchronous wheel, a wire drum, a sprocket, and the like, which is not specifically limited in this embodiment of the present application. The output of the first driving unit 410 is provided with a driving wheel, the first flexible transmission member 420 can wind and pass through the driving wheel, and a pressing wheel can be arranged on one side, deviating from the driving wheel, of the first flexible transmission member 420, and the pressing wheel can be positioned to ensure that the first flexible transmission member 420 and the driving wheel are always in effective contact, so that slipping is avoided, and the accuracy of the moving position of the lifting device 300 is further ensured.

Wherein an order group includes one or more orders. For example, multiple orders to be sorted may be sorted into multiple order groups according to the rate of coincidence of the goods, and orders for the same order group may be assigned to the same workstation.

It will be appreciated that the cargo coincidence rate refers to the coincidence rate of target cargos of different orders being located in the same raw material box or raw material boxes with storage locations close to each other, and the controller of the workstation may preset a cargo coincidence rate threshold, for example, the cargo coincidence rates are 40%, 50%, 60%, 70%, 80%, etc., which is not limited in detail in the embodiments of the present application. When the received goods coincidence rate of the orders reaches or exceeds the threshold value, the corresponding orders are distributed to form an order group.

It should be noted that, a plurality of workstations may be provided in the warehouse system, and orders in an order group are distributed to the same workstation, so as to improve the processing efficiency of the orders, and when the raw material boxes corresponding to the orders in the order group are carried, the carrying times and the carrying paths may be reduced, and the logistics efficiency is improved.

S202, sending a plurality of carrying tasks to a carrying mechanism according to the goods information of the order to be sorted in the order group distributed by the workstation.

The handling equipment can be a handling robot or other movable automatic handling devices, and the controller of the workstation can send control instructions to the handling equipment in a wireless communication mode, wherein each control instruction can comprise one or more handling tasks.

In some embodiments, sending a plurality of transfer tasks to a transfer mechanism based on the cargo information of the order to be sorted in the order group assigned by the workstation may include the steps of:

step one: and obtaining the average line-to-order ratio and the average order coincidence rate of all the current orders of the workstation.

Step two: and determining the number of the carrying tasks according to the number of orders of the workstation, the average line-to-order ratio and the average order coincidence rate.

Wherein, the number of the transporting tasks can be calculated according to the formula m=n×r×α; m is the number of handling tasks, N is the number of orders, R is the average line-to-order ratio, and alpha is the average order coincidence rate. The average line-to-single ratio is the average of the line-to-single ratios of all orders, e.g., the line-to-single ratio of a single line order is 1 and the line-to-single ratio of two line orders is 2; the average order coincidence rate is the tie-down cargo coincidence rate of all orders.

S203, selecting a carrying task to be executed currently according to the number of empty library bits of the buffer mechanism of the workstation, and controlling the carrying mechanism to execute the carrying task to be executed currently; the caching mechanism is used for storing order boxes with incomplete picking tasks.

It can be understood that the number of the empty library bits of the buffer mechanism can be dynamically changed along with the sorting task of the workstation, and the controller of the workstation can acquire and monitor the number of the empty library bits of the buffer mechanism in real time, select a carrying task according to the real-time numerical value of the number of the empty library bits, and send the selected carrying task to the carrying mechanism in the form of a control instruction.

In some embodiments, selecting the currently performed transport task based on the number of empty library bits of the buffer mechanism of the workstation may include the steps of:

Judging whether the number of the empty warehouse bits of the buffer mechanism is larger than a dynamic warning value, if so, indifferently selecting a carrying task, and if not, selecting the carrying task which does not occupy the empty warehouse bits.

Therefore, when the number of the empty storage bits is larger than the dynamic warning value, the fact that enough empty storage bits in the buffer mechanism can be used for placing new order boxes is indicated, and therefore no difference in selection can be carried out on the carrying tasks. When the number of the empty warehouse bits is smaller than or equal to the dynamic warning value, the defect that the number of the empty warehouse bits in the buffer mechanism is insufficient is indicated, and if an order box corresponding to the selected transport task occupies a new empty warehouse bit, the buffer mechanism can be possibly full to explode, so that the transport task which does not occupy the empty warehouse bit is selected at the moment, the workstation can continuously and stably run, and the risk of explosion of the buffer mechanism can be avoided.

It should be noted that the dynamic alert value may be a preset value in the controller of the workstation, and may be set or adjusted according to a specific logistics rate of the workstation.

In some embodiments, when the order is a single line order, then multiple single line orders are combined into one aggregate order and the aggregate order is treated as one order, wherein the aggregate order includes a single line of aggregate orders and multiple lines of aggregate orders.

For example, the handling tasks that do not occupy the empty stock may include handling tasks corresponding to a single row of multiple orders or a single row of aggregate orders, and handling tasks corresponding to a plurality of rows of orders or a tail row and a middle row of aggregate orders.

It is understood that a single line of individual orders means that the order has only one target item. A single line multiple order means that the order has multiple target items and the multiple target items can be sorted by a single sorting operation, e.g., multiple target items are located in the same bin. Multiple line multiple piece orders refer to orders having multiple target items that require multiple sorting operations to complete sorting, e.g., multiple target items in multiple different bins, respectively.

In some embodiments, determining whether the number of empty library bits of the caching mechanism is greater than a dynamic alert value may specifically include the steps of:

step one: and acquiring the number of the empty warehouse positions of the buffer mechanism and the number of the empty warehouse positions to be generated after the current carrying task is sorted.

Step two: and determining a dynamic warning value according to the number of the empty library bits to be occupied and the number of the empty library bits to be generated.

Illustratively, determining the dynamic alert value based on the number of empty bank bits to be occupied and the number of empty bank bits to be generated specifically includes:

and determining the dynamic warning value according to a formula S-T=Q, wherein S is the number of empty storage bits of the buffer mechanism to be occupied after the current carrying task is sorted, T is the number of empty storage bits to be generated after the current carrying task is sorted, and Q is the dynamic warning value.

In the order processing method provided in the embodiment of the present application, after the handling mechanism is controlled to execute the handling task to be executed currently, the method further includes the following steps:

if the handling task is a handling task corresponding to a single-row multi-order or a single-row aggregate list, the control workstation acquires an empty order box, and after the single-row multi-order or the single-row aggregate list corresponding goods are delivered to the order box, the control workstation conveys the order box to a workstation outlet.

Wherein, single-row multiple orders or single-row aggregate orders can complete picking tasks only by one picking operation without temporary storage. The workstation outlet refers to a downstream outlet of the order conveying line along the conveying direction, and the order boxes flowing out of the workstation outlet can enter the next logistics process, such as packaging and the like.

It will be appreciated that a multi-line order or multi-line aggregate order may include a top line and a bottom line, or may include a top line, a middle line, and a bottom line, where each line of the order corresponds to a handling task when an order is picked, and the handling tasks corresponding to the top line, middle line, and bottom line may be performed sequentially.

For example, when a multi-line order or multi-line aggregate order includes a first line, a second line, a third line, and a fourth line, corresponding to four handling tasks, the first line acts as a first line, the second line acts as a third line acts as a middle line, and the fourth line acts as a last line.

If the handling task is a handling task corresponding to a plurality of rows of orders or a plurality of rows of collection orders, the control workstation acquires order boxes corresponding to the plurality of rows of orders or the plurality of rows of collection orders from the buffer mechanism, and after goods corresponding to the tail rows are delivered to the order boxes, the control workstation conveys the order boxes to a workstation outlet.

If the handling task is a handling task corresponding to a plurality of rows of orders or a plurality of rows of collection orders, the control workstation acquires an order box corresponding to the orders or the plurality of rows of collection orders from the buffer mechanism, and after goods corresponding to the middle row are delivered to the order box, the control workstation conveys the order box to the buffer mechanism for buffer storage.

If the transport task is the transport task corresponding to the first line of the multi-line order or the multi-line collection list, the control workstation acquires the empty order box, and after goods corresponding to the first line are delivered to the order box, the control workstation conveys the order box to the caching mechanism for caching.

In some embodiments, before sending the plurality of handling tasks to the handling mechanism according to the cargo information of the order to be sorted of the workstation, the method may further comprise the steps of:

step one: the sorting efficiency of the workstation and the carrying efficiency of the carrying mechanism are obtained.

Step two: and determining the number of the conveying mechanisms according to the sorting efficiency and the conveying efficiency.

It will be appreciated that the handling mechanisms may be of different types, different similar handling mechanisms may have different handling efficiencies, and combinations of different handling mechanisms may be employed in determining the number of handling mechanisms based on sorting efficiency and handling efficiency.

For example, when the average time for taking a raw material box to stay at the taking place is 6S, that is, when the workstation consumes one raw material box every 6S, the handling mechanism needs to complete one handling task within 6S, wherein the handling efficiency of the first handling mechanism is 80 boxes/h, that is, 45S/box, and the handling efficiency of the second handling mechanism is 20 boxes/h, that is, 180S/box, and 7.5 first handling mechanisms and 30 second handling mechanisms are required to meet the speed of the workstation 6S/box. In the practical process, 8 first conveying mechanisms and 30 second conveying mechanisms are distributed, so that the raw material box requirements of the workstation can be met. The specific raw material box consumption rate of the workstation and the carrying efficiency of the carrying mechanism are not particularly limited.

It should be noted that, the order processing method provided by the embodiment of the application can select a corresponding carrying task according to the dynamic change of the number of the empty warehouse bits of the caching mechanism, so that the situation that the caching mechanism explodes a warehouse in the cargo sorting process is avoided, the cargo delivery sorting process can be ensured to run continuously and efficiently, and the cargo sorting efficiency is improved.
