Description

Technical Field

[0001] The present invention relates to the field of transportation technology, and in particular to a track transportation system and method. Background Art

[0002] In the garment industry, a track conveyor system consisting of multiple tracks is usually used to complete the processes of shelving, storage, screening and packaging of garments. Figure 1 As shown, in the existing track conveyor 100, finished garments, such as tops and pants (not shown), enter the main storage track 110 through the top rack track 101 and the pants rack track 102, and then enter the storage tracks 111. Since the tops and pants are produced on different production lines and enter the main storage track 110 in different orders, the tops and pants are not arranged in the order of pairing, but are mixed and stored on the storage tracks 103. When it is necessary to package the tops and pants that are paired (for example, with the same size, color or style) together, the tops and pants need to be screened and paired.

[0003] In the existing track conveying system 100, the tops and pants entering the warehouse can be hung on carriers (not shown) such as hangers and hooks, and the carriers are provided with identification information related to the tops or pants carried (for example, bar codes, QR codes, RFID chips, etc. regarding size, color, style, etc.). When screening and pairing are required, the clothes stored on each storage track 111 can enter the main track 120 for outbound storage, and then enter each screening track 121. A screening reader 122 and a screening entry device 123 are provided at the connection between each screening track 121 and the main track 120 for outbound storage, which can read the information on the carrier and allow the tops and pants that meet the set order to enter each screening track 121. For example, Figure 1The upper three of the six screening tracks 121 shown in the figure are used to store tops in a set order of "1, 2, 3...", and the lower three are used to store pants in the same order. A packaging reader 103 and a packaging entry device 104 can be set at the connection between each packaging track 105 and the output main track 130, which can read the information on the carrier and allow the tops and pants to be screened to enter the packaging track 105. When it is necessary to screen out the paired tops and pants (for example, the tops and pants in the order of "3"), the tops and pants in the order of "1", "2" and "3" on the corresponding screening track 121 can be transported to the output main track 130. When the package reader 103 reads that the paired tops and pants with the sequence "3" arrive at the packaging track 105, the packaging entry device 104 allows them to enter the packaging track 105, while the tops and pants with the sequences "1" and "2" continue to move on the output main track 130, and can return to the outbound main track 120 via the screening return track 125, and can enter each screening track 121 again.

[0004] In the above-mentioned existing track conveying system, the main tracks on both sides of each screening track 121 need to be occupied, that is, the outbound main track 120 and the output main track 130, and the carrier needs to run on these tracks for many times, which makes the pressure on the main tracks on both sides too large, affecting the entry of new carriers on the main tracks, and the running time is long, the work efficiency is low, and it is impossible to meet the fast processing rhythm. In particular, when there are more categories, styles, colors, and sizes of ready-made clothes stored and they need to be screened and matched, the pressure on the main track is greater, and the reduction in work efficiency is more obvious.

[0005] In addition to the garment industry, similar problems also exist in other industries that use rail conveyor systems to convey other items and need to screen and pair them. For example, in the logistics industry, multiple items from multiple tracks belonging to the same order need to be packaged together at the same packaging station. In the manufacturing industry, parts from multiple tracks belonging to the same product need to be assembled together at the same station. Therefore, it is necessary to improve the existing rail conveyor system and method so as to reduce the pressure on the main track while achieving item screening and pairing, shorten the operating time, and improve work efficiency.

[0040] It should be noted that, in this article, "articles" may refer to articles that can be transported on a track by various carriers such as hooks, hanging baskets, hangers, suction cups, trays, etc., wherein the article itself may or may not have such a carrier. In the case where the article itself does not have such a carrier, an appropriate carrier (e.g., a hanger) may be attached to the article or the article may be placed in a carrier (e.g., a hanging basket). The article itself or the carrier may be provided with identification information related to the article (e.g., a barcode, a QR code, an RFID chip, etc.). In the following, only ready-made clothes (e.g., tops, pants, etc.) hanging on hangers are described as examples of articles, but the articles described herein may include any articles that can be transported on a track, such as food to be packaged, medicines, and parts to be assembled.

[0041] It should also be pointed out that, in this article, words such as "first", "second", etc. are only used for descriptive purposes to distinguish one entity from another, and should not be understood as indicating or implying the relative importance between each other or implicitly representing the order and quantity of related technical features.

[0042] Reference below Figures 2 to 5To describe the track conveyor system of the present invention.

[0043] like Figure 2 As shown, the track conveying system 200 of the present invention may include an input main track 210, an output main track 220, and a plurality of screening tracks 230. The input main track 210 may be configured to receive a plurality of objects with corresponding identification information, the output main track 220 may be configured to output one or more of the objects, and the plurality of screening tracks 230 may be disposed between the input main track 210 and the output main track 220, and may be configured to receive a plurality of objects from the input main track 210 and to convey one or more of the objects to be screened out to the output main track 220. In addition, the track conveying system 200 of the present invention may further include a control unit (not shown), which may be configured to control a plurality of objects to enter the plurality of screening tracks 230 from the input main track 210 and to release one or more of the objects to be screened out from the plurality of screening tracks 230 to the output main track 220.

[0044] It should be noted that for the sake of clarity and simplicity, Figures 2 to 5 In the figure, only a few items on some tracks are schematically shown in the form of short vertical lines, and different identification information of the items is represented by numbers, but the present invention is not limited to the content of the figure, and this simplification does not affect the understanding of the concept of the present invention. In addition, Figures 2 to 5 The arrows in the figure indicate the direction in which the items move on the corresponding track.

[0045] According to an exemplary embodiment of the present invention, Figure 2 As shown, located Figure 2 The three screening tracks 230 at the lower part include a first circular track 240. The first circular track 240 may be configured to allow a plurality of articles to circulate on the first circular track 240. The first circular track 240 may have a first entry member 241 and a first release member 242, wherein the first entry member 241 is connected to the input main track 210, the first release member 242 is connected to the output main track 220, and a first circular track reader 243 is provided at the first release member 242. It should be noted that although Figure 2 Only three of the four screening tracks are shown to include the first annular track 240, but the present invention is not limited thereto, but may include 1, 2, 3, 5, 6 or more screening tracks, and there may be fewer or more screening tracks including the first annular track 240. For example, according to the amount of identification information such as product category, style, color and size to be conveyed, the number of screening tracks that may include the first annular track 240 may be appropriately adjusted. In summary, the effect of the present invention can be achieved if at least one screening track 230 includes the first annular track 240.

[0046] In the track conveying system 200 of the present invention, the control unit can be configured to output instructions, which may include identification information of one or more items to be screened out from the multiple items, and the control unit can also be configured to cause the multiple items to move in a circular motion on the first circular track 240, and allow one or more items to be screened out from the multiple items to be released from the first circular track 240 by reading the identification information of one or more items to be screened out from the multiple items by the first circular track reader 243.

[0047] For example, in the example of the track conveying system 200 being used in the clothing industry, the items may refer to ready-made clothes (e.g., tops / pants), which may be conveyed to the input main track 210, for example, through the top rack track 101 / pants rack track 102, and then enter the first circular track 240 of each screening track 230 in an indefinite order. Figure 2 For example, when the control unit outputs an instruction to filter out the garments with identification information such as "6", the garments can be moved cyclically on the first circular track 240. When the garment with identification information "6" moves to the first release member 242 of the first circular track 240, the first circular track reader 243 can read that the identification information of the garment is "6". Therefore, the control unit can control the first release member 242 to release the garment with identification information "6" from the first circular track 240, thereby realizing the screening function. The filtered garments with identification information "6" can be transported to the output main track 220, and then transported to the packaging track 105 for packaging.

[0048] Therefore, by using a circular track that is independent of the main track, the specified garments can be screened out without occupying the input main track 210 and the output main track 220 on both sides, thereby reducing the burden on the main track, shortening the operating time and improving work efficiency.

[0049] In addition, when the articles are circulated on the first annular track 240, the effects of blowing and dehumidification can be achieved. For example, in the clothing industry, the clothes can be independently circulated on the first annular track 240 to achieve the effects of blowing and dehumidification without affecting the work of other tracks. In addition, compared with the linear track, more articles can be stored on the first annular track 240, so the dedicated storage track can be omitted, and the screening track plays the functions of storage and screening, so that the structure of the entire track conveying system is more compact.

[0050] Continuing with the example of the track conveying system 200 used in the clothing industry, the ready-made clothing may include a plurality of tops (which may be referred to as first items) and a plurality of pants (which may be referred to as second items) that can be paired, and the plurality of screening tracks 230 may include a first screening track 231 and a second screening track 232, such as Figure 2As shown. The first screening track 231 can be configured to receive a plurality of tops, and the second screening track 232 can be configured to receive a plurality of trousers. Therefore, different articles can be transported to different screening tracks for separate screening, thereby improving the screening efficiency.

[0051] by Figure 2 Taking the following two screening tracks shown in as an example, the first screening track 231 and the second screening track 232 each include a first circular track 240. When it is necessary to screen out the paired tops and trousers, the control unit can output an instruction containing the identification information of the paired tops and trousers to be screened out. As described above, the control unit can make the tops and trousers circulate on the corresponding first circular tracks 240 of the first screening track 231 and the second screening track 232, respectively, and allow the paired tops and trousers to be screened to be released from the first circular track 240 of the first screening track 231 and the first circular track 240 of the second screening track 232, respectively, by reading the identification information of the paired tops and trousers to be screened out by the corresponding first circular track reader 243, and the control unit can be configured to allow the paired tops and trousers to be screened to be released alternately from the first screening track 231 and the second screening track 232. Therefore, the paired tops and trousers can be screened out, and advantages such as improved efficiency, cyclic dehumidification and storage of a large number of items can be achieved.

[0052] like Figure 2 As shown, the track conveying system 200 of the present invention may include a plurality of screening tracks 230 of different structures. Figure 2 Taking the above two screening tracks in the example, the first screening track 231 may include a first circular track 240, and the second screening track 232 is formed in the form of a linear track. Therefore, the first circular track 240 allows a plurality of first objects to move cyclically thereon, while the second screening track is configured to allow a plurality of second objects to move one way thereon.

[0053] It should be noted that, in this article, a circular track refers to a track that is connected end to end to form a closed circular path, but the geometric shape of the circular track is not limited to a circular ring. For example, tracks that are connected end to end to form a closed path such as an ellipse or a rectangle can be considered as circular tracks. In addition, in this article, a linear track refers to a track that is not connected end to end to form a one-way path, but the geometric shape of the linear track is not limited to a straight line. For example, a linear track can be a track in the shape of a curve, a broken line, etc.

[0054] like Figure 2 As shown in the two screening tracks above, the identification information and arrangement order of the plurality of second objects conveyed to the second screening track 232 can be recorded by the control unit. For example, a plurality of pants are arranged in the order of identification information "1, 2, 3...". It should be noted that Figure 2 The sequence of identification information "1, 2, 3..." shown in the figure is only for the purpose of illustration and does not limit the technical solution of the present invention to be implemented in the sequence shown in the figure. In fact, the arrangement sequence can be obtained by recording the identification information of the plurality of second objects transported to the second screening track 232 in sequence. Therefore, the plurality of second objects on the second screening track 232 in the form of a linear track can be released in the arrangement sequence.

[0055] In this case, the instruction output by the control unit may include identification information of a plurality of first items and a plurality of second items that can be paired in batches and the corresponding relationship between them. For example, a top and pants with the same identification information can be paired. Moreover, the control unit may be configured to allow the plurality of first items to be released from the first circular track 240 in the above arrangement order by reading the identification information of the plurality of first items that can be paired in batches with the plurality of second items by the first circular track reader 243 in the above arrangement order. For example, the pants on the second screening track 232 are arranged in the order of "1, 2, 3...", while the tops on the first screening track 231 are arranged in an indefinite order in the first circular track 240. When the control unit outputs the instruction, the plurality of tops move cyclically on the first circular track 240, and when the top with the identification information "1" that meets the above arrangement order moves to the first release member 242, the first circular track reader 243 may read the identification information of the top as "1", so the control unit may control the first release member 242 to release the top with the identification information "1" from the first circular track 240. Subsequently, when the top with the identification information "2" that conforms to the above arrangement sequence moves to the first release member 242, the first circular track reader 243 can read the identification information of the top as "2", so the control unit can control the first release member 242 to release the top with the identification information "2" from the first circular track 240. By analogy, the multiple tops on the first circular track 240 can be released in the arrangement sequence with the trousers on the second screening track 232. Based on the above release process, the control unit can be configured to allow the multiple tops and multiple trousers that can be paired to be alternately released from the first screening track 231 and the second screening track 232 in the above arrangement sequence, so that screening pairing can be achieved.

[0056] It should be pointed out that in Figure 2 In the embodiment shown, two different sets of screening tracks appear, namely, the two screening tracks of the lower set have the same structure, each having a circular track, while the two screening tracks of the upper set have different structures, one having a circular track and the other in the form of a linear track. However, the present application is not limited thereto, but screening tracks of the lower set or the upper set may also be used.

[0057] According to another exemplary embodiment of the present invention, the track conveying system 200 of the present invention may further include a plurality of screening tracks 230 of additional configuration. Figure 3 Taking the above two screening tracks in the example, the first screening track 231 includes a second circular track 250 in addition to the first circular track 240. The second circular track 250 is configured to allow a plurality of first objects to circulate on the second circular track 250, and the second circular track 250 has a second entry member 251 and a second release member 252. The second entry member 251 is connected to the first release member 242 of the first circular track 240, and the second release member 252 is connected to the output main track 220, and a second circular track reader 253 is provided at the second release member 252. In the track conveying system of such a structure, a plurality of first objects released from the first circular track 240 in the above arrangement order can be conveyed to the second circular track 250 and arranged in the above arrangement order on the second circular track 250.

[0058] Therefore, by allowing the plurality of first objects to circulate on the first circular track 240, the plurality of first objects in order can be temporarily stored on the second circular track 250. That is, the arrangement order of the plurality of first objects on the second circular track 250 corresponds to the arrangement order of the plurality of second objects on the second screening track 232. When batch pairing is required, the control unit can be configured to allow the plurality of first objects and the plurality of second objects in batch pairing to be released alternately from the first screening track 231 and the second screening track 232 according to the above arrangement order, so that efficient batch screening pairing can be achieved.

[0059] Alternatively, Figure 3 Taking the following two screening tracks in the example, the first screening track 231 includes not only the first circular track 240 but also the first linear track 260, and the first linear track 260 is configured to allow a plurality of first objects to move one-way on the first linear track 260, wherein the first end of the first linear track 260 is connected to the first release member 242 of the first circular track 240, and the second end is connected to the output main track 220. In the track conveying system of such structure, the plurality of first objects released from the first circular track 240 in the above arrangement sequence can be conveyed to the first linear track 260 and arranged in the above arrangement sequence on the first linear track 260. Therefore, the plurality of first objects in the order can be temporarily stored on the first linear track 260. When batch pairing is required, the control unit can be configured to allow the plurality of first objects and the plurality of second objects to be paired in batches to be alternately released from the first screening track 231 and the second screening track 232 in the above arrangement sequence, so that efficient batch screening pairing can be achieved.

[0060] At once Figure 3For the two sets of screening tracks shown in FIG, the second circular track 250 can store more items than the first linear track 260. Figure 3 In the embodiment shown, two different screening tracks appear, that is, the first screening track 231 in the lower screening track has a first circular track 240 and a first linear track 260, while the first screening track 231 in the upper screening track has a first circular track 240 and a second circular track 250, and the second screening tracks 232 in both groups are in the form of linear tracks. However, the present application is not limited thereto, but the screening tracks in the form of the lower group or the upper group can also be used, or can be combined with Figure 2 Either or a combination of the two sets of screening tracks shown in .

[0061] like Figure 2 and Figure 3 As shown, the track conveying system 200 may also include a plurality of packaging tracks 105, and each of the plurality of packaging tracks 105 may be configured to receive a paired first article and a second article having corresponding identification information and package them together. Accordingly, the package reader 103 and the package entry device 104 disposed at the connection between each packaging track 105 and the output main track 130 may read the identification information of the paired first article and the second article and allow them to enter the packaging track 105.

[0062] like Figure 2 and Figure 3 As shown, the track conveying system 200 may also include a plurality of entry devices 212 and a plurality of release devices 222. The plurality of entry devices 212 may be arranged at the connection between each of the plurality of screening tracks 230 and the input main track 210 and may allow a plurality of articles to enter the corresponding screening track from the input main track 210 according to the instruction of the control unit. The plurality of release devices 222 may be arranged at the connection between each of the plurality of screening tracks 230 and the output main track 220 and may allow one or more of the plurality of articles to be screened to be released from the corresponding screening track to the output main track 220 according to the instruction of the control unit. For example, the entry device 212 and the release device 222 may be a commonly used turnout mechanism. Since there are many similar devices in the prior art, this article will not further describe them in detail.

[0063] In order to allow different objects to enter different screening tracks, the track conveying system 200 may further include a plurality of first screening readers 211 and a plurality of second screening readers 221 for reading identification information of a plurality of objects, wherein the plurality of first screening readers 211 are arranged at the connection between the plurality of screening tracks 230 and the input main track 210, and the plurality of second screening readers 221 are arranged at the connection between the plurality of screening tracks 230 and the output main track 220. By combining the screening readers with the entry device and the release device, the identification information and arrangement order of the objects entering and discharged from the plurality of screening tracks 230 can be effectively controlled.

[0064] Although the rail transport system 200 is provided as a separate system in the above-described embodiment, it can also be combined with an existing rail transport system to achieve technical transformation of the existing rail system. Figure 4 and Figure 5 As shown, the rail conveying system 200 of the present invention can be installed downstream of an existing rail conveying system without major modifications to the existing rail conveying system.

[0065] Therefore, according to another exemplary embodiment of the present invention, the rail conveying system 200 may further include: an inbound main rail 110, a plurality of storage rails 111, and an outbound rail 120, wherein the inbound main rail 110 is configured to receive a plurality of articles, the plurality of storage rails 111 are configured to receive a plurality of articles from the inbound main rail 110 and store the plurality of articles on the plurality of storage rails 111, and the outbound main rail 120 is configured to receive a plurality of articles from the plurality of storage rails 111 and convey the plurality of articles to the input main rail 210. In such a modified rail conveying system, the storage rails and the screening rails of the existing rail conveying system may be used together as storage rails.

[0066] The track conveying system 200 described above can be used to implement the track conveying method of the present invention, so as to more effectively implement the screening and pairing of multiple items. Figures 2 to 5 Based on the combination Figures 6 to 8 The track transportation method S100 of the present invention is described.

[0067] like Figure 6 As shown, the track conveying method of the present invention is in step S10 (as shown in Figure 6Starting from the dotted box in the middle, multiple items are received by inputting the main track 210. In step S10, the following sub-steps may be included: reading identification information of the item (sub-step S11) and determining whether the item needs to enter the screening track (sub-step S12). If the item needs to enter the screening track, the next step S20 is entered: the multiple items are allowed to enter at least one of the multiple screening tracks 230. Otherwise, the items may be allowed to pass directly (sub-step S13).

[0068] As described above, at least one of the plurality of screening tracks 230 includes a first annular track 240, the first annular track 240 includes a first entry member 241 and a first release member 242, the first entry member 241 is connected to the input main track 210, the first release member 242 is connected to the output main track 220, and the first annular track 240 is configured to allow a plurality of articles to circulate on the first annular track 240. For further details about the plurality of screening tracks, please refer to the above.

[0069] At step S30, the control unit outputs an instruction, wherein the instruction includes identification information of one or more items to be screened out from the plurality of items.

[0070] At step S40 , the plurality of objects are moved cyclically on the first circular track 240 , and at step S50 , the identification information of the plurality of objects is read by using the first circular track reader 243 disposed at the first release member 242 of the first circular track 240 .

[0071] At step S60, by reading the identification information of one or more items to be screened out from the multiple items, one or more of the items are released from the first circular track 240. Specifically, step S60 may include a sub-step S61 of determining whether the identification information of the current item corresponds to the identification information included in the instruction. If yes, the current item is released from the first circular track 240 (sub-step S62), otherwise, the current item continues to move on the first circular track 240 (sub-step S63).

[0072] At step S70, the current article can be released from at least one of the plurality of screening tracks 230 to the output main track 220. Then, at step S90, one or more articles with corresponding identification information are sent to the packaging track 105 through the output main track 220.

[0073] Therefore, it can be seen from the above method steps that by utilizing the first circular track that circulates independently of the main track, designated items can be screened out without occupying the main tracks on both sides, thereby reducing the burden on the main track, shortening the operating time and improving work efficiency.

[0074] According to another exemplary embodiment of the present invention, the track conveying method of the present invention can be applied to the screening and pairing of multiple items. Specifically, the multiple items include multiple first items and multiple second items that can be paired, and the multiple screening tracks 230 include a first screening track 231 and a second screening track 232, the first screening track 231 is configured to receive multiple first items, and the second screening track 232 is configured to receive multiple second items.

[0075] In this embodiment, the first screening track 231 and the second screening track 232 may each include a first circular track 240, wherein the instruction output by the control unit may include identification information of the paired first and second items to be screened out. Figure 7 As shown, the track transport method S100 in this embodiment may include Figure 6 The steps of the track conveying method S100 of the embodiment are similar to those of the embodiment shown in FIG. 1 , except that individual steps need to be adjusted accordingly. Therefore, repeated descriptions of similar steps will be omitted. Specifically, in step S10 (such as Figure 7 Starting from the dotted box in the middle, a plurality of first items and a plurality of second items are received by inputting the main track 210. In step S10, the following sub-steps may be included: reading identification information of the item (sub-step S11) and determining whether the item needs to enter the screening track (sub-step S12), if the item needs to enter the screening track, proceed to the next sub-step S14, otherwise, the item can be directly passed (sub-step S13): at sub-step S14, determining whether the current item is the first item or the second item, if it is the first item, making it enter the first screening track 231 (sub-step S21), otherwise making it enter the second screening track 232 (sub-step S22), wherein sub-steps S21 and S22 may constitute step S20.

[0076] Similarly, at step S30, the control unit outputs an instruction, wherein the instruction includes identification information of the paired first and second items to be screened. At step S40, the plurality of first items and the plurality of second items are respectively moved cyclically on the corresponding first circular tracks 240, and at step S50, the identification information of the plurality of first items and the plurality of second items is read by using the corresponding first circular track readers 243 disposed at the first release member 242 of the first circular track 240.

[0077] In step S60 , the first circular track reader 243 is used to read identification information of multiple first objects cyclically moving on the first circular track 240 of the first screening track 231 , and identification information of multiple second objects cyclically moving on the first circular track 240 of the second screening track 232 .

[0078] Then, at step S60, the identification information of the paired first and second items to be screened is read to allow them to be alternately released from the first circular track 240 of the first screening track 231 and the first circular track 240 of the second screening track 232. Specifically, step S60 may include a sub-step S61 of determining whether the identification information of the current item (first item / second item) corresponds to the identification information included in the instruction. If yes, the current item (first item / second item) is released from the corresponding first circular track 240 (sub-step S62), otherwise the current item continues to move on the corresponding first circular track 240 (sub-step S63).

[0079] Then, at step S70, the paired first items and the second items to be screened are alternately released from the first screening track 231 and the second screening track 232, and at step S90, the paired first items and the second items with corresponding identification information can be sent to the packaging track 105 through the output main track 220.

[0080] According to another exemplary embodiment of the present invention, the track conveying method S100 of the present invention can be applied to batch screening and pairing of multiple items. Specifically, the first screening track 231 includes a first circular track 240, and the second screening track 232 is formed in the form of a linear track and is configured to allow multiple second items to move one-way on the second screening track 232, wherein the instruction output by the control unit includes the identification information of multiple first items that can be paired in batches and the identification information of multiple second items and the corresponding relationship between them. Figure 8 As shown, the track transport method S100 in this embodiment may include Figure 7 The steps of the track conveying method shown in FIG. 100 are similar to those of the track conveying method shown in FIG. 100 , except that individual steps need to be adjusted accordingly. Therefore, repeated descriptions of similar steps will be omitted. Specifically, the track conveying method S100 also includes: recording the identification information and arrangement order of the plurality of second objects conveyed to the second screening track 232 (step S23). In addition, at step S50, the identification information of the plurality of first objects that are circulated and moved on the first circular track 240 of the first screening track 231 is read by the first circular track reader 243. Then in step S60, the identification information of the plurality of first objects that can be batch-paired with the plurality of second objects is read by the first circular track reader 243 in accordance with the above arrangement order, so that the plurality of first objects are released from the first circular track 240 in accordance with the above arrangement order. Similarly, step S60 may also include the above-mentioned sub-steps S61, S62 and S63.

[0081] Then, at step S70, the batch paired first items and second items to be screened are alternately released from the first screening track 231 and the second screening track 232, and at step S90, the paired first items and second items with corresponding identification information can be sent to the packaging track 105 through the output main track 220.

In this embodiment, the track conveying method S100 can also include step S81 (such as Figure 8 : The plurality of first objects released from the first circular track 240 in the above arrangement sequence are transported to the second circular track 250 and arranged in the above arrangement sequence on the second circular track 250.

[0083] Alternatively, the second circular track 250 may be replaced by a first linear track 260, which is configured to allow a plurality of first objects to move one-way on the first linear track 260, wherein a first end of the first linear track 260 is connected to the first release member 242 of the first circular track 240, and a second end of the first linear track 260 is connected to the output main track 220. Similarly, the track transport method S100 may further include step S82 (e.g., Figure 8 : The plurality of first objects released from the first circular track 240 in the above arrangement order are conveyed to the first linear track 260 and arranged on the first linear track 250 in the above arrangement order.

[0084] Then, at step S90 , the batch-paired plurality of first objects and the plurality of second objects having corresponding identification information may be sent to the packaging track 105 through the output main track 220 .

[0085] It should be noted that some of the steps described above may be performed in a different order or simultaneously.

[0086] According to the above description, the track conveying system and method of the present invention utilizes a ring track that circulates independently of the main track, and can realize the screening and pairing of items without occupying the main tracks on both sides, thereby reducing the burden on the main track, shortening the operating time and improving work efficiency.
