[0064] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0065] First, in order to facilitate understanding of the body-in-white and skid conveying system provided by the present application, the following detailed explanation is now made: The existing body-in-white storage line is currently built in a fixed line form, and this layout lacks sufficient flexibility to support reverse storage operations, that is, it is impossible to flexibly arrange or adjust the inventory position, thereby limiting the functionality and efficiency of the storage line, especially when it is necessary to quickly respond to production changes or optimize inventory management. Another existing stereoscopic warehouse, although it can randomly select storage locations for different models to enter the warehouse, but because the body-in-white of commercial vehicles is higher, it requires a large height space in the workshop. For conventional workshops, on the one hand, it cannot meet the construction requirements; on the other hand, after the construction is successful, the storage capacity is small, and the stereoscopic warehouse equipment cost is high, the space utilization rate is low, and there is a lack of skid storage area. Therefore, it is not suitable for large-scale promotion.

[0066] The present application provides a body-in-white and skid conveying system, which realizes the classified storage problem of various different types of vehicles on a plane by utilizing aerially arranged lines, overcomes the limitations in design, and can flexibly adapt to the needs of classified storage of body-in-white of various types of vehicles. While having high flexibility and adaptability, it further improves the utilization rate of storage space and production efficiency.

[0067] like Figure 1 The body-in-white and sled conveying system shown in the figure comprises: a storage roller mechanism 1; one end of the storage roller mechanism 1 is respectively connected to the rough sorting warehouse 6 and the first transfer conveying mechanism 3, and the other end is connected to the sled return roller mechanism 8;

[0068] Wherein, a second transfer and conveying mechanism 4 is arranged on a side of the rough sorting storehouse 6 away from the first transfer and conveying mechanism 3;

[0069] The first transfer conveying mechanism 3 is arranged on the other side of the rough sorting storehouse 6, and is used to convey the parts from the storage roller mechanism 1 to the rough sorting storehouse 6; the other side of the first transfer conveying mechanism 3 away from the rough sorting storehouse 6 is connected to the third transfer conveying mechanism 5 through the fine sorting storehouse 2;

[0070] The third transfer conveying mechanism 5 is connected to the coating roller mechanism 7 and the sled return roller mechanism 8 respectively, and is used to transport the parts in the fine sorting warehouse 2 to the painting workshop through the coating roller mechanism 7 and to transfer the sled stored on the sled return roller mechanism 8 to the rough sorting warehouse 6.

[0071] Specifically, the warehousing roller mechanism 1 is used to transport the sled carrying parts (such as white body) to the fine sorting warehouse 2 through the first transfer conveying mechanism 3, or directly to the rough sorting warehouse 6; wherein, when directly transported to the rough sorting warehouse 6, the sled and the parts can be transported to the second transfer conveying mechanism 4 through a storage lane in the rough sorting warehouse 6, and then the sled and the parts are distributed and transported to other storage lanes of the rough sorting warehouse 6 through the second transfer conveying mechanism 4; then the sled carrying the parts is finally transported from the fine sorting warehouse 2 to the coating roller mechanism 7 through the third transfer conveying mechanism 5 until it is transported to the coating workshop.

[0072] In the paint shop, the unloading operation of the body-in-white on the sled is completed, and the unloaded sled is returned to the sled return roller mechanism 8 for storage, stacking and maintenance operations.

[0073] Furthermore, the storage roller structure 1 includes: a plurality of first friction roller beds 11 connected in series and a rotating roller bed 12; wherein the rotating roller bed 12 is arranged at one end close to the rough sorting warehouse 6 or the first transfer conveying mechanism 3, and the other end opposite to the rotating roller bed 12 is set as the parts storage end; the parts storage end is connected to one end of the slide return roller mechanism 8.

[0074] It can be understood that the present application first sequentially numbers the BIWs entering the storage roller structure; then, the numbered BIWs are transported to the first transfer conveying mechanism 3 or to the rough sorting warehouse 6 through the rotating roller bed.

[0075] The rotating roller bed 12 can realize the connection path between the storage roller structure and the first transfer conveying mechanism 3 and the rough sorting warehouse 6, which has high transportation flexibility and adaptability.

[0076] Furthermore, a slide removal mechanism 9 is provided on one side of the parts storage end; the slide removal mechanism 9 is used to transfer the slide without parts at the storage end position to an external welding workshop.

[0077] Specifically, the sled removal mechanism 9 is a lift; a transfer fork is installed on the lift; the lift is used to transport the sled without the body-in-white to the external welding workshop, and through the external welding workshop, the body-in-white is installed on the sled again, and then the product is put into storage through the storage roller mechanism 1.

[0078] Furthermore, the rough sorting library 6 comprises: a plurality of first storage lanes arranged in parallel; wherein the plurality of first storage lanes arranged in parallel are arranged between the first transfer conveying mechanism 3 and the second transfer conveying mechanism 4; wherein the first transfer conveying mechanism 3 and the second transfer conveying mechanism 4 are arranged in parallel and perpendicular to the arrangement direction of the plurality of first storage lanes;

[0079] Among the multiple first storage lanes, the first storage lane 66 close to the side of the storage roller mechanism 1 is set as the first reverse storage roller lane, and the first storage lane 61 away from the side of the storage roller mechanism 1 is set as a slide bidirectional roller lane; wherein each first storage lane includes a plurality of second friction roller beds connected in series.

[0080] In this embodiment, the rough sorting warehouse 6 includes six first storage lanes 61, 62, 63, 64, 65, and 66 arranged in parallel; among them, the first first storage lane 66 located on the front side is designed as a first reverse storage roller conveyor, and the first first storage lane 61 located on the rear side is designed as a sled bidirectional roller conveyor; the other four first storage lanes 62, 63, 64, and 65 can be used to store the body in white and / or the sled; at the same time, the six first storage lanes are arranged between the first transfer conveying mechanism 3 and the second transfer conveying mechanism 4; through the first transfer conveying mechanism 3 and the second transfer conveying mechanism 4, in cooperation with the first reverse storage roller conveyor and the sled bidirectional roller conveyor, the storage, scheduling and other operations of the body in white and / or the sled in and out of the warehouse are realized.

[0081] It should be noted that, in addition to their own functions, the first reverse storage roller conveyor and the slide bidirectional roller conveyor of the present application can also be used to store white bodies or slides.

[0082] Specifically, the design concept of the rough sorting warehouse 6 of the present application is that, first, it can store and remove the white body from the warehouse to the fine sorting warehouse 2; secondly, the white body can be roughly sorted or pre-stored through the rough sorting warehouse 6 (the sequential numbering of parts has a high degree of disorder); at the same time, it has a circular reverse warehouse function; in addition, the rough sorting warehouse 6 is used to store the skid and remove the skid.

[0083] Specifically, the design of the coarse sorting library 6 provides service support for the fine sorting library 2, and improves the flexibility and adaptability of the entire storage space, further improving space utilization and production efficiency; it can be understood that the layout of the coarse sorting library 6 has a certain compactness, and in actual applications, the length and number of the first storage channels can be adjusted according to the plane area, and is not limited to the embodiment of the six first storage channels in this embodiment.

[0084] Furthermore, the fine sorting library 2 is arranged and connected between the first transfer and conveying mechanism 3 and the third transfer and conveying mechanism 5; the fine sorting library 2 includes a plurality of second storage lanes arranged in parallel;

[0085] The second storage track 24 close to the storage roller track mechanism 1 among the plurality of the second storage tracks is set as the second reverse storage roller track; the second storage track 23 adjacent to the second reverse storage roller track is set as a fast roller track;

[0086] Each second storage track includes a plurality of third friction roller beds connected in series.

[0087] In this embodiment, the fine sorting warehouse 2 includes four second storage lanes 21, 22, 23, and 24 arranged in parallel, among which the first second storage lane 24 located on the front side is designed as a second reverse storage roller lane, and the second storage lane 23 adjacent to one side of the second reverse storage roller lane is designed as a fast roller lane; the other second storage lanes 21 and 22 are all used to store white bodies.

[0088] Specifically, the design concept of the fine sorting warehouse 2 adopted in the present application is: first, it can store and unload the BIW to the coating roller mechanism 7; second, it can accurately sort the BIW (that is, the sequence number of the parts has a high degree of continuity), and has a reverse storage function and a function of quickly unloading the BIW; in addition, it can transport the stacked skids to the rough sorting warehouse 6 for storage.

[0089] It can be understood that the fine sorting library 2, with the support and cooperation of the rough sorting library 6 and by utilizing its own structural design layout, has a faster response mechanism, and the space utilization and productivity have been significantly improved. The overall system has the characteristics of high flexibility, accuracy, reliability and efficiency.

[0090] Furthermore, the first friction roller bed 11, the second friction roller bed and the third friction roller bed of the present application have the same structure and are all used to drive the slide to move, and all include:

[0091] The frame 300; a plurality of friction wheels 301 are arranged at intervals in the length direction on both sides of the frame 300; wherein the front and rear ends of the friction wheel 301 located at the front side have limiting protrusions, and the friction wheel 301 located at the rear side has no limiting protrusions; the friction wheels 301 arranged at the corresponding ends are connected through a connecting rod 302; wherein the connecting rod 302 is provided with a belt guide part 303 at a position close to the rear friction wheel 301; two adjacent connecting rods 302 are connected by a transmission belt 304 wrapped around the belt guide part 303; the upper ends of the friction wheels 301 on both sides of the frame 300 can contact the slide;

[0092] The frame 300 is also equipped with a driving motor 305; the output shaft of the driving motor 305 is connected to the belt guide parts 303 on the left and right two adjacent connecting rods 302 through a transmission belt 304, thereby driving the friction wheels 301 on both sides of the frame 300 to roll, thereby driving the slide to move.

[0093] Furthermore, the frame 300 is also provided with a detection device 306 and an RFID reader; the stopping of the driving motor 305 is controlled by the feedback of the detection device 306; and the body-in-white vehicle model information on the skid is read by the RFID reader.

[0094] Furthermore, the first transfer and conveying mechanism 3, the second transfer and conveying mechanism 4 and the third transfer and conveying mechanism 5 have the same structure and include:

[0095] The rotary conveyor track 100 and the rotary conveyor 101 slidably connected to the rotary conveyor track 100; wherein the rotary conveyor tracks 100 included in the first transfer conveying mechanism 3, the second transfer conveying mechanism 4 and the third transfer conveying mechanism 5 are arranged in parallel with each other.

[0096] Furthermore, the slide return roller mechanism 8 comprises:

[0097] A first sled conveying roller 80; one end of the first sled conveying roller 80 is connected to the storage roller mechanism 1, and the other end is connected to one side of the first rotating roller bed 82;

[0098] The other side of the first rotating roller bed 82 is connected to the second sled conveying roller table 81;

[0099] One end of the second sled conveying roller 81 away from the first sled conveying roller 80 is connected to the second rotating roller bed 83;

[0100] One side of the second rotating roller bed 83 is connected to a sled return conveying roller 84 , and the other side can be connected to the rotating transfer machine 101 included in the third transfer conveying mechanism 5 through a third sled conveying roller 85 .

[0101] A sled maintenance mechanism is also provided between the first rotating roller bed 82 and the second sled conveying roller 81; the sled maintenance structure 86 includes: a third rotating roller bed located between the first rotating roller bed 82 and the second sled conveying roller 81; wherein one side of the third rotating roller bed is connected to the sled maintenance roller 861; and a sled dismantling stacker 87 is also provided on the third sled conveying roller 85.

[0102] The coating roller mechanism 7 , the first sled conveying roller 80 , the second sled conveying roller 81 , and the third sled conveying roller 85 all include a plurality of fourth friction roller beds connected in series; wherein the fourth friction roller bed has the same structure as the first friction roller bed 11 .

[0103] Specifically, the present application receives the sled that has completed the unloading of the white body from the paint shop through the sled return conveyor roller 84 included in the sled return roller mechanism 8; then stacks it through the sled destacker 87 on the sled return conveyor roller 84, and then passes through the fine sorting warehouse 2, and finally transports it to the rough sorting warehouse 6 for storage.

[0104] It can be understood that in the present application, whether the empty skid is to be sent out of the warehouse or put into the warehouse is determined based on the comparison result of the generation speed of the empty skid returned from the paint shop and the consumption speed of the empty skid; it can be understood that if the generation speed of the empty skid is lower than the consumption speed, then it enters the rough sorting warehouse 6 for storage; otherwise, the skid is sent out of the warehouse.

[0105] It is further explained that the skids repaired by the skid repair structure 86 or the skids stacked by the skid dismantling and stacking machine 87 can also be transported to an external welding workshop via another path (i.e., transported to an external welding workshop via the first skid conveying roller 80 through the skid removing mechanism 9).

[0106] It can be understood that the body-in-white and skid conveying system provided by the present application overcomes the technical problem that it is impossible to store multiple types of vehicles in a planar system; and by utilizing the aerial arrangement of wires, the utilization rate of the three-dimensional space is further improved; secondly, through the optimized layout of the body-in-white and skid conveying system, it has high flexibility and adaptability, the production efficiency has been greatly improved, and it has a lower cost.

[0107] On the other hand, the present application provides a method for conveying a body in white and a skid, comprising the following steps:

[0108] Based on the digital identification on the upper end of the sled of the storage roller mechanism 1, the vehicle model data of the first part on the upper end of the sled is sequentially obtained in a rolling manner;

[0109] Based on the comparison result between the first part information and the production plan, a target identification of the target part is generated; the target identification includes at least: part grouping information and sequence number information;

[0110] Based on the target identifier, corresponding warehousing and outbound tasks are executed according to different warehousing strategies; wherein the warehousing and outbound tasks at least include: a first warehousing task and a first outbound task.

[0111] Specifically, the body-in-white produced in the external welding shop is transported to the storage roller mechanism 1 by a skid;

[0112] The PLC control system reads the digital identification on the sled through the RFID reader to obtain the vehicle model data of the body-in-white on the sled, and sends the data to the central control system through network transmission;

[0113] The central control system compares the vehicle model data with the production plan and sequentially generates the target identification of the target; the target identification of each target part includes: part grouping information and unique sorting number information; among which, the sorting number information can be rolled in real time as the body-in-white is shipped out of the warehouse; for example, when a body-in-white is shipped out of the warehouse, the sorting number information of all the target parts that have been put online will automatically decrease by one.

[0114] The sled carrying the BIW passes through the RFID reader on the rotating roller bed included in the storage roller mechanism 1, and reads the BIW model data and sorting number in the digital identification (tag carrier) on the sled again, and sends the data to the central control system through network transmission again; the central control system analyzes different storage strategies according to the sorting number of the BIW.

[0115] The central control system issues different warehousing and outbound tasks according to different warehousing strategies.

[0116] Furthermore, the first warehousing task includes:

[0117] The steps for storing the refined sorting library include:

[0118] The slide and the parts on the upper end are sequentially conveyed to the fine sorting warehouse through the storage roller mechanism 1 and the first transfer conveying mechanism 3.

[0119] For example, the BIW is input into the fine sorting warehouse through the rotating roller bed of the storage roller mechanism 1 and the first transfer conveying mechanism 3 .

[0120] The steps of storing the rough sorting library 6 include:

[0121] The sled and the parts on the upper end of the sled are sequentially conveyed to the other first storage track of the rough sorting warehouse through the storage roller mechanism 1, the second reverse storage roller of the rough sorting warehouse and the second transfer conveying mechanism 4.

[0122] For example, the goods are directly put into the first inverted roller conveyor in the rough sorting warehouse through the rotating roller bed of the warehouse-in roller conveyor mechanism 1, and then transported to the rough sorting warehouse by the second transfer conveyor mechanism 4.

[0123] The steps for skid storage include:

[0124] The returned sled on the sled return roller mechanism 8 is transported to the sled destacker 87;

[0125] Control the rotary moving machine 101 included in the third transfer conveying mechanism 5 to move to the sled stacker 87 to perform the sled receiving machine operation;

[0126] The skid on the third transfer and conveying mechanism 5 that has completed the pick-up is transported to the rough sorting warehouse through the second inverting roller of the fine sorting warehouse and the first transfer and conveying mechanism in sequence.

[0127] For example, according to the instruction of the central control system, the empty skid returned on the skid return conveying roller 84 is transferred to the skid disassembling and stacking machine 87 through the second rotating roller bed 83;

[0128] The skid dismantling and stacking machine 87 stacks the transferred skids according to the instructions; for example, three skids are stacked together, occupying the plane position of one skid;

[0129] The central control system sends instructions to the rotary transfer machine included in the third transfer and conveying mechanism 5; the rotary transfer machine drives the servo motor through the intelligent servo technology to accurately reach the skid return conveying roller, and completes the machine receiving operation from the skid return conveying roller;

[0130] The third transfer conveying mechanism 5 includes a rotary transfer machine, which sends the skid with the body-in-white to the second inverted storage roller in the fine sorting warehouse according to the instruction, and transports it to the first transfer conveying mechanism via the second inverted storage roller, and finally sends it to the skid bidirectional roller in the rough sorting warehouse for storage.

[0131] Furthermore, the first outbound task includes:

[0132] Parts outbound steps include:

[0133] Based on the parts database detection, it is determined whether the fine sorting library and the rough sorting library have target parts with matching target sorting numbers;

[0134] If the detection result is none, then, within a preset time, the target sorting number data of the matching target part is included in the queue insertion sequence, and the digital identifiers in the fine sorting library and the rough sorting library are readjusted to obtain the target identifier that matches the target sorting number data;

[0135] If the adjusted target identifier includes a target identifier that matches the target sorting number, and the target part corresponding to the matching target identifier is located in the refined sorting library, then the storage location of the target part in the refined sorting library is obtained;

[0136] Based on the storage position of the target part in the fine sorting library, the target part is transported to the coating roller mechanism 7 via the third transport transfer mechanism;

[0137] If the adjusted target identifier includes a target identifier that matches the target sorting number, and the target part corresponding to the matched target identifier is located in the rough sorting library, then the storage location of the target part in the rough sorting library is obtained;

[0138] Based on the storage position of the target parts in the rough sorting warehouse, the target parts are transported from the rough sorting warehouse to the coating roller mechanism 7 through the first transfer conveying mechanism and the fine sorting warehouse in sequence.

[0139] Example

[0140] The central control system determines whether there is a body-in-white with a sorting number of 1 in the fine sorting library and the rough sorting library according to the database;

[0141] If there is no body-in-white numbered 1 in the database of the central control system's fine sorting library and the rough sorting library, the central control system will include the body-in-white model data corresponding to this target number in the queue-jumping queue after 5 minutes, and reduce the sorting numbers of all the body-in-white that have been online by 1. After the corresponding body-in-white in the queue-jumping queue comes online, it will be given priority to leave the warehouse.

[0142] If the adjusted target identifier includes a target identifier that matches the target sorting number, and the target part corresponding to the matching target identifier is located in the refined sorting warehouse, the sled carrying the BIW is transported from the refined sorting warehouse to the coating roller mechanism 7 through the third transfer conveying mechanism 5 to remove the BIW from the warehouse.

[0143] The first outbound task also includes a skid outbound step.

[0144] The steps of skid unloading include:

[0145] The first transfer conveying mechanism is controlled to transport the skids stored in the rough sorting warehouse to the skid return roller mechanism via the fast roller conveyor included in the fine sorting warehouse and the third transfer conveying mechanism, and the skids leaving the warehouse are destackered by the skid destacker.

[0146] The first outbound task also includes:

[0147] The steps of precise sorting and reversing include:

[0148] If the target part matching the target sorting number is located in the refined sorting library, then, based on the storage location of the target part, the first storage channel storing the target part is obtained, and the first storage channel storing the target part is defined as the designated target storage channel;

[0149] Controlling the rotary moving machine included in the third transfer and conveying mechanism to move to the designated target storage lane side;

[0150] If the digital identifier of the first storage part on the designated target storage lane does not match the target identifier of the target part, the precision sorting warehouse reverse operation is performed through the third transfer conveying mechanism until the digital identifier of the first storage part on the first target storage lane matches the target identifier of the target part, and the precision sorting warehouse reverse operation is completed; then, the target part is transported from the precision sorting warehouse to the coating roller mechanism 7 through the third transfer conveying mechanism, and the target part is transported to the coating roller mechanism 7 via the coating roller mechanism 7.

[0151] Steps for reversing the sorted library:

[0152] The third transfer conveying mechanism transports the unmatched first storage part on the designated target storage lane to the second storage roller track in the precision sorting library 2 through the rotary transfer machine 200 included in the third transfer conveying mechanism 5, and then returns to the designated target storage lane through the first transfer conveying mechanism 3, completing a cycle. When the digital identifier of the first storage part on the designated target storage lane matches the target identifier of the target part, the precision sorting storage operation step is completed.

[0153] The steps of rough sorting and reversing include:

[0154] If the target part matching the target sorting number is located in the coarse sorting library, then based on the storage location of the target part, a second storage channel storing the target part is obtained, and the second storage channel storing the target part is defined as a selected target storage channel;

[0155] Controlling the rotary moving machine included in the first transfer conveying mechanism to move to the side of the selected target storage lane;

[0156] If the digital identifier of the first storage part on the selected target storage lane does not match the target identifier of the target part, the rough sorting and reverse storage operation is performed through the first transfer conveying mechanism until the digital identifier of the first storage part on the second target storage lane matches the target identifier of the target part, and the rough sorting and reverse storage operation is completed; then, the target part is transported from the rough sorting warehouse to the fine sorting warehouse through the first transfer conveying mechanism, and then the target part is transported from the fine sorting warehouse to the coating roller mechanism 7 through the third transfer conveying mechanism, and the target part is transported to the coating workshop via the coating roller mechanism 7.

[0157] The steps of the rough sorting and reverse stocking operation include:

[0158] The first transfer conveying mechanism transports the unmatched first storage part on the selected target storage track through the rotating roller bed 12 of the storage roller mechanism 1, and then to the second transfer conveying mechanism 4 via the first reverse storage roller of the rough sorting library 6, and then transports the unmatched first storage part to the selected target storage track via the second transfer conveying mechanism 4, completing a cycle. When the digital identification of the first storage part on the selected target storage track matches the target identification of the target part, the rough sorting reverse storage operation is completed.

[0159] It can be understood that by implementing a grouping mechanism for the body-in-white and assigning sorting numbers to the body-in-white, the operations of warehousing, reversing and exiting are performed according to the sorting numbers, thereby improving the efficiency and accuracy of exiting the warehouse; secondly, by arranging plane lines in the air, the three-dimensional space is fully utilized, the utilization rate of the space is improved, and the investment cost is reduced.
