Description

Technical Field

[0001] The present invention relates to the technical field of warehousing, and particularly to a multi-layer warehousing system with multi-level screening. Background Art

[0002] After the production of clothes is completed, according to the actual production requirements, supply deadlines, etc., it is possible to selectively implement immediate packing and storage or enter the hanging warehousing system for storage. After entering the warehousing system, it can be batch-output according to the supply demand.

[0003] However, the current warehousing system is a single-layer structure. The planar structure occupies a large amount of warehouse space, while the vertical structure occupies a relatively small amount of warehouse space, resulting in low space utilization. When implementing the warehousing function for goods, the throughput is small. For a large number of goods, multiple warehouses are often required to complete the effective warehousing or out-warehousing of a single batch of order goods. The warehousing / out-warehousing of goods requires multiple individual warehousing systems to query and cooperate for invocation, which is rather wasteful of manpower and material resources. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a multi-layer warehousing system with multi-level screening, which makes full use of the space in the warehouse to set up a multi-layer warehousing structure, greatly increases the throughput of a single warehouse, and performs multi-level screening on the carriers in the warehousing system to achieve efficient and accurate goods warehousing and out-warehousing operations.

[0005] The technical solution for the present invention to solve the problem is to provide a multi-layer warehousing system with multi-level screening, including an in-warehouse lifting track, a sorting in-warehouse track, a secondary in-warehouse track, a multi-layer storage track, a secondary out-warehouse track, and a sorting out-warehouse track. The secondary in-warehouse track and the secondary out-warehouse track are respectively arranged at both ends of the multi-layer storage track. The secondary in-warehouse track and the secondary out-warehouse track are vertical multi-layer ring tracks, and each layer of track in the multi-layer ring track is correspondingly connected to each layer of storage track in the multi-layer storage track. The in-warehouse lifting track extends from the in-warehouse area to the warehousing area and is connected to one end of the sorting in-warehouse track. The other end of the sorting in-warehouse track is unidirectionally input-connected to the secondary in-warehouse track, so that the carrier can enter the multi-layer storage track from the in-warehouse area to complete in-warehouse storage. There is a unidirectional input connection between the secondary out-warehouse track and the sorting out-warehouse track located in the warehousing area. The sorting out-warehouse track extends from the warehousing area to the out-warehouse area, so that the carrier can be transported from the multi-layer storage track to the out-warehouse area to complete out-warehousing.

There is a one-way input connection between the downward section of the convex part of the out-warehouse sorting loop track and the secondary in-warehouse track, so that the vehicle on the sorting and in-warehouse track can be input into the secondary in-warehouse track.

[0009] Preferably, an in-warehouse identification device and an out-warehouse detection device are respectively provided at both ends of the temporary track. The in-warehouse identification device includes a passive induction identification module and a visual identification module. The out-warehouse detection device includes a passive induction identification module.

[0010] Further, an in-warehouse lifting section is provided on the track on the side of the high-position part of the in-warehouse lifting track close to the convex part of the in-warehouse sorting loop track. There is a one-way input connection between the high position of the downward section of the in-warehouse lifting section and the low position of the downward section of the convex part of the in-warehouse sorting loop track.

[0011] Further, the one-way input connection is realized through a sorting slide rail. One end of the sorting slide rail is provided with a sorting structure and is docked with the high-position track, and the other end of the sorting slide rail is merged with the low-position track, so that the vehicle on the high-position track can slide down through the sorting structure and be merged onto the low-position track.

[0012] Preferably, the sorting structure can be a sorting device or a rail-splitting structure. Among them, the sorting device has a sorting effect and can identify and sort vehicles, sorting the required vehicles into the track. The rail-splitting structure does not have a substantial sorting effect and puts all the passing vehicles into the track.

[0013] Further, the multi-layer storage track includes at least two layers of storage tracks. A plurality of single tracks are arranged in parallel in each layer of storage track. An in-warehouse identification device and an out-warehouse detection device are respectively provided at both ends of the single track. The in-warehouse identification device includes a passive induction identification module and a visual identification module. The out-warehouse detection device includes a passive induction identification module.

[0014] Further, the secondary incoming storage track and the secondary outgoing storage track are vertical multi-layer ring tracks, and the secondary incoming storage track and the secondary outgoing storage track are symmetrically arranged at both ends of the multi-layer storage track; the multi-layer ring track includes at least two horizontal straight tracks for docking with the single-track, and semi-circular large curved tracks and small curved tracks are respectively arranged at both ends of the horizontal straight tracks at the top layer and the bottom layer, and the large curved tracks at the top layer and the large curved tracks at the bottom layer are respectively located at two side ends of the horizontal straight track; small curved tracks are arranged at both ends of the horizontal straight track at the middle layer; the large curved track at the top layer is connected to the large curved track at the bottom layer through an inclined track, and the remaining small curved tracks are sequentially connected through inclined tracks from the top layer to the bottom layer to form the multi-layer ring track.

[0015] Further, an abnormal sorting track is also arranged in the storage area, and the incoming storage sorting ring track, the outgoing storage sorting ring track, the secondary incoming storage track, and the secondary outgoing storage track are sequentially connected to the abnormal sorting track in a one-way input manner through a plurality of sorting sliding rails.

[0016] Further, an outgoing storage lifting section is arranged on one side of the sorting outgoing storage track close to the secondary outgoing storage track in the storage area, and the secondary outgoing storage track is connected to the downward section of the outgoing storage lifting section in a one-way input manner, so that the carrier on the secondary outgoing storage track can slide down to the sorting outgoing storage track; a plurality of outgoing storage sliding rails are arranged on the sorting outgoing storage track in the outgoing storage area.

[0017] Preferably, an arc-shaped sliding rail can be erected between the incoming storage sorting ring track and the temporary track. The upper end of the arc-shaped sliding rail is docked with the main track from the lower side of the main track of the incoming storage sorting ring track, and a telescopic structure is arranged on the main track behind the docking position. When the telescopic structure retracts, there is a gap in the main track, and the carrier slides down along the arc-shaped sliding rail; when the telescopic structure extends, the main track is closed, and the carrier runs along the main track. The lower end of the arc-shaped sliding rail is directly docked with the temporary track, so that the carrier can slide down and enter the temporary track.

[0018] The carrier on the temporary track can be limited and conveyed by a bird hook.

[0019] A guiding sliding rail is arranged between the temporary track and the outgoing storage sorting ring track to guide the carrier on the temporary track to fall onto the outgoing storage sorting ring track.

[0020] Preferably, the secondary incoming storage track, the secondary outgoing storage track and the single-track can be arranged in the same way as the incoming storage sorting ring track, the outgoing storage sorting ring track and the temporary track.

[0021] The beneficial effects of the present invention are as follows:

[0022] The present invention is a multi-level screening multi-layer storage system, which designs a multi-layer storage structure to store incoming goods, and based on the storage track design, multi-level screening is carried out to control the incoming and outgoing of the carrier, which is beneficial to the automated management operation of the system.

[0023] At both ends of the multi-layer storage structure, loop tracks of multi-layer structures are designed. For the storage tracks on each layer, loading and unloading operations are carried out, and the goods on the multi-layer storage structure are integrated for unified output or batch output.

[0024] There is line-of-sight obstruction between multi-layer storage structures. In this application, online detection is set on each single track with storage function to replace manual visual inspection; if it is a double-layer structure, the single tracks in the storage area can be misaligned to provide a certain visual inspection adjustment, which can be used in conjunction with online detection.

Detailed Embodiments

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0035] To solve the above problems, the present invention proposes a multi-level screening multi-layer storage system. Please refer to Figure 1 、 Figure 2 、 Figure 3 , which mainly includes an in-warehouse lifting track 2, a sorting in-warehouse track 3, a secondary in-warehouse track 4, a multi-layer storage track 5, a secondary out-warehouse track 6, and a sorting out-warehouse track 7. The secondary in-warehouse track 4 and the secondary out-warehouse track 6 are respectively arranged at both ends of the multi-layer storage track 5. The secondary in-warehouse track 4 and the secondary out-warehouse track 6 are vertical multi-layer ring tracks, and each layer of the track in the multi-layer ring track is correspondingly connected to each layer of the storage track in the multi-layer storage track 5. The in-warehouse lifting track 2 extends from the in-warehouse area to the storage area and is connected to one end of the sorting in-warehouse track 3. The other end of the sorting in-warehouse track 3 is unidirectionally input-connected to the secondary in-warehouse track 4, so that the carrier can enter the multi-layer storage track 5 from the in-warehouse area to complete in-warehouse storage. There is a unidirectional input connection between the secondary out-warehouse track 6 and the sorting out-warehouse track 7 located in the storage area. The sorting out-warehouse track 7 extends from the storage area to the out-warehouse area, so that the carrier can be transported from the multi-layer storage track 5 to the out-warehouse area to complete out-warehouse.

[0036] Please refer to Figure 1 . In this application, the interior of the warehouse is basically divided into three areas: an in-warehouse area, an out-warehouse area, and a storage area. Among them, the in-warehouse area and the out-warehouse area are parallel and located on both sides of the warehouse entrance for easy inbound and outbound. The storage area is located inside, behind the in-warehouse area and the out-warehouse area.

[0037] As shown in Figure 1 of this application, the combined form of each area in the warehouse is generally in an "L" shape. Thus, two warehouses can be combined in a complementary form to form a "cuboid". The warehouse entrances face different directions, and the occupied area of the warehouse can be arranged with the "cuboid" as the basic unit, leaving corresponding access roads, without wasting limited surface space and maximizing the use of storage space.

[0038] In the embodiments of this application, the in-warehouse lifting track 2 extends from the in-warehouse area to the storage area, gradually increasing the track height, so that the carrier and clothing entering from the shelving point can be transported to a high enough position and enter the storage system for storage.

[0039] Specifically, the in-warehouse lifting track 2 includes a low-position part, a lifting part, and a high-position part. The low-position part is located in the in-warehouse area, the high-position part is located in the storage area, and the lifting part is located between the low-position part and the high-position part.

[0040] The track of the lifting part is set to slope upward, and the height gradually increases from the low-position part to the high-position part to lift the height of the vehicle.

[0041] The low-position part is close to the ground and is in an overall horizontal state. As a loading point, multiple in-warehouse elevators 1 can be set to assist in loading the vehicle.

[0042] The high-position part is far from the ground and is used to connect to the sorting and in-warehouse track 3. A local protrusion is provided on one side close to the sorting and in-warehouse track 3, in a trapezoidal shape, forming an in-warehouse lifting section 21, which can further lift the running height of the vehicle and perform track separation operations during the downward movement of the vehicle, separating the vehicle and conveying it to the in-warehouse sorting loop track 31, and relying on the self-weight and inertia of the vehicle to complete track separation, realizing the one-way input connection from the in-warehouse lifting track 2 to the sorting and in-warehouse track 3.

[0043] Exemplarily, an in-warehouse lifting section 21 is provided on the track on the side of the protrusion of the high-position part of the in-warehouse lifting track 2 close to the in-warehouse sorting loop track 31, in a trapezoidal shape, and specifically includes an upward section, a horizontal section, and a downward section. Based on the running direction of the in-warehouse lifting track 2, the vehicle is first lifted in height through the upward section, maintains the height through the horizontal section, and performs track separation operations during the downward section; there is a one-way input connection between the high position of the downward section of the in-warehouse lifting section 21 and the low position of the downward section of the protrusion of the in-warehouse sorting loop track 31. It can be understood that the heights of the downward section of the in-warehouse lifting section 21 and the downward section of the protrusion of the in-warehouse sorting loop track 31 are basically the same, and there is a sufficient height difference from the high position to the low position of the downward section, which can enable the vehicle to complete track separation and sliding relying on its self-weight and inertia.

[0044] It can be understood that the in-warehouse lifting track 2 is in the form of a loop track, and the hooks used to hang the vehicle on it can be recycled.

[0045] In a specific embodiment, the sorting and in-warehouse track 3 specifically includes a temporary storage track and in-warehouse sorting loop tracks 31 and out-warehouse sorting loop tracks 32 provided at both ends of the temporary storage track. The temporary storage track includes multiple single-piece temporary tracks arranged in parallel. A protrusion is provided on the track structure on the side of the in-warehouse sorting loop track 31 close to the in-warehouse lifting section 21, in a trapezoidal shape; on the side of the track structure far from the in-warehouse lifting section 21 corresponding to the temporary storage track, a horizontal part is provided. A protrusion is provided on the track on the side of the out-warehouse sorting loop track 32 close to the secondary in-warehouse track 4, in a trapezoidal shape; on the side of the track structure far from the secondary in-warehouse track 4 corresponding to the temporary storage track, a horizontal part is provided.

[0046] For the relative height relationship among the in-warehouse sorting loop track 31, the temporary storage track, and the out-warehouse sorting loop track 32, please refer toFigure 3 The front end of the temporary track is docked with the horizontal part of the high-level incoming sorting loop track 31, and the rear end of the temporary track is docked with the horizontal part of the low-level outgoing sorting loop track 32.

[0047] There is a one-way input connection between the high-level part (the high level of the descending section) of the incoming lifting track 2 and the descending section (the low level) of the raised part of the incoming sorting loop track 31, so that the vehicle passing through the high-level part can be input into the sorting incoming track 3; the descending section of the raised part of the outgoing sorting loop track 32 is connected to the secondary incoming track 4 in a one-way input manner, so that the vehicle on the sorting incoming track 3 can be input into the secondary incoming track 4.

[0048] It can be understood that an incoming recognition device and an outgoing detection device are respectively arranged at both ends of the temporary track. The incoming recognition device includes a passive induction recognition module and a visual recognition module; the outgoing detection device includes a passive induction recognition module. The passive induction recognition module can be composed of a passive chip carried on the vehicle and an inductor arranged on the track to realize the recognition and detection of the vehicle; the visual recognition module can capture photos of the clothes carried on the vehicle based on a visual camera to provide the basic conditions for visual recognition and detection.

[0049] In the embodiment of the present application, the multi-layer storage track 5 includes at least two layers of storage tracks, and multiple single tracks are arranged in parallel in each layer of storage track. In the present application, two layers of storage tracks are taken as an example for illustration:

[0050] The storage track located at the high level is referred to as the high-level track for short, and the storage track located at the low level is referred to as the low-level track for short. When only two layers of storage tracks are included, the high level is the top layer and the low level is the bottom layer.

[0051] The high-level track and the low-level track can be arranged in alignment, and each single track is aligned up and down. After the vehicle enters the track, the line of sight of the high-level track is blocked by the low-level track, and it does not have good visual inspection conditions. Therefore, an incoming recognition device and an outgoing detection device can be respectively arranged at both ends of the single track. The incoming recognition device includes a passive induction recognition module and a visual recognition module; the outgoing detection device includes a passive induction recognition module. The visual recognition module can replace manual visual inspection for visual recognition and detection to form an online visual inspection. As another implementation manner, the high-level track and the low-level track can be arranged in a staggered manner to reserve a certain visual inspection space to provide visual inspection conditions for the staff.

[0052] The secondary entry rail 4 and the secondary exit rail 6 are vertical multi-layer ring rails, and the secondary entry rail 4 and the secondary exit rail 6 are symmetrically arranged at the two ends of the multi-layer storage rail 5; the multi-layer ring rail includes at least two layers of horizontal straight rails for docking with the single rail, and semi-circular large curved rails and small curved rails are respectively arranged at the two ends of the horizontal straight rails located at the top layer and the bottom layer, and the large curved rails of the top layer and the large curved rails of the bottom layer are respectively located at the two side ends of the horizontal straight rails; for example, the large curved rail of the horizontal straight rail of the top layer is located on the left side, and the small curved rail is located on the right side, and the large curved rail of the horizontal straight rail of the bottom layer is located on the right side, and the small curved rail is located on the left side; small curved rails are arranged at both ends of the horizontal straight rails located in the middle layer; the large curved rail of the top layer is connected to the large curved rail of the bottom layer by an inclined rail, and the remaining small curved rails are connected from the top layer to the bottom layer by inclined rails in sequence, thereby forming a multi-layer ring rail.

[0053] It can be understood that the number of layers of the multi-layer loop rail corresponds to the number of layers of the multi-layer storage rail, preferably two to three layers, and the secondary warehouse entry rail 4 and the secondary warehouse exit rail 6 can maintain a high operating efficiency to perform warehouse entry and exit operations. When the number of layers of the multi-layer storage rail is two layers, there is no middle layer, and the small curved rail of the top layer rail is directly connected to the small curved rail of the bottom layer through an inclined rail, such as Figure 7 shown.

[0054] In an embodiment of the present application, the sorting and unloading rail 7 includes a high portion, a descending portion, and a low portion, wherein the high portion is located in the storage area, the low portion is located in the unloading area, and the descending portion is located between the high portion and the low portion to lower the height of the carrier.

[0055] The high position of the sorting and unloading rail 7 in the storage area is higher than the ground. A trapezoidal exit lifting section 71 is arranged on the rail structure on the side close to the secondary exit rail 6. The secondary exit rail 6 is connected to the descending section of the exit lifting section 71 in a one-way input manner, so that the carrier on the secondary exit rail 6 can slide down to the sorting and unloading rail 7.

[0056] The distance between the sorting and unloading rails 7 and the ground is relatively low in the low position of the unloading area, and a lowering point can be set. A plurality of unloading slide rails 8 are arranged in parallel to lower the carriers on the sorting and unloading rails 7 for packaging.

[0057] In the embodiments of the present application, the one-way input connection between the entry lifting rail 2 and the entry sorting ring rail 31, the exit sorting ring rail 32 and the secondary entry rail 4, and the secondary exit rail 6 and the sorting exit rail 7 can all be achieved through the sorting slide rail 9.

[0058] Specifically, the sorting slide rail 9 performs a bridging function and is installed and used in an inclined manner as a whole. A sorting structure is arranged at one end (high end) of the sorting slide rail 9 and docked with the track at the high position, and the other end (low end) of the sorting slide rail 9 is combined with the track at the low position, so that the carrier on the high track can slide down through the sorting structure and merge onto the track at the low position. Figure 5 shown.

[0059] The sorting structure can be an electrically controlled sorting device or a fixed rail-splitting structure. Among them, the sorting device has a sorting effect, can identify and sort carriers, sort the required carriers into the track, and has a clear purpose to identify and sort carriers; the rail-splitting structure does not have a substantial sorting effect, separates and sorts all carriers passing through this place into the track, and directly transfers all carriers to different tracks, as Figure 6 shown in

[0060] In a specific embodiment, an arc-shaped slide rail can be installed between the inbound sorting loop rail 31 and the temporary rail. The upper end of the arc-shaped slide rail is docked with the main rail (horizontal part) of the inbound sorting loop rail 31 from the lower side of the main rail (horizontal part), and a telescopic structure is arranged on the main rail behind the docking position, as Figure 4 shown. When the telescopic structure retracts, there is a gap in the main rail, allowing the carrier to slide down along the arc-shaped slide rail; when the telescopic structure extends, the main rail closes, and the carrier runs along the main rail. The lower end of the arc-shaped slide rail is directly docked with the temporary rail, enabling the carrier to slide down into the temporary rail.

[0061] The carrier on the temporary rail can be limited and conveyed by a bird hook. A guiding slide rail is arranged between the temporary rail and the outbound sorting loop rail 4 to guide the carrier on the temporary rail to fall onto the outbound sorting loop rail 4.

[0062] It can be understood that the secondary inbound rail, secondary outbound rail and single-track can be set in the same way as the inbound sorting loop rail, outbound sorting loop rail and temporary rail mentioned above.

[0063] In the embodiment of the present application, for carriers with problems, they can be not sorted into different tracks. Problem carriers may appear on the inbound sorting loop rail 31, outbound sorting loop rail 32, secondary inbound rail 4, and secondary outbound rail 6. These problem carriers can be transferred through the abnormal sorting rail 10 to avoid the influence of the accumulation of a large number of problem carriers on the load of the loop rail.

[0064] Specifically, an abnormal sorting rail 10 is also set in the storage area. Based on the layout of the inbound sorting loop rail 31, outbound sorting loop rail 32, secondary inbound rail 4, and secondary outbound rail 6, it is overall linear. The inbound sorting loop rail 31, outbound sorting loop rail 32, secondary inbound rail 4, and secondary outbound rail 6 are sequentially connected to the abnormal sorting rail 10 in a one-way input manner through multiple sorting slide rails 9. The high-position ends of the multiple sorting slide rails 9 are docked with the above-mentioned respective rails, and the low-position ends of the sorting slide rails 9 are docked with the abnormal sorting rail 10.

[0065] It can be understood that based on the running directions of the respective rails, the sorting slide rail 9 can be selectively connected to the inner rail or outer rail of the abnormal sorting rail 10, as Figure 1 shown in. A processing station can be set at one end of the abnormal sorting rail 10 to process the abnormal carriers on it.

[0066] The content described above can be implemented alone or in various combinations, and these variant ways are all within the protection scope of the present invention.

[0067] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.
