[0002] Currently, the commonly used method in goods warehousing is to place the goods in a container, then classify the containers, set identifiers, and place the containers in different shelves according to the identifiers. Conveying equipment, such as stackers and shuttle cars, is used to convey the goods between different storage modules in the warehousing system. In the above-mentioned goods warehousing system, the erection of the shelves is cumbersome, the floor area is large, the classification and handling of the containers require a large amount of manpower, the conveying equipment is relatively expensive, and it also requires a considerable amount of operating space. Therefore, the above-mentioned goods warehousing system has the problems of cumbersome shelf erection and high costs of the shelves and conveying equipment.

[0003] Moreover, when such a goods warehousing system is applied to some industries where the goods are in the form of soft sheets, such as the clothing industry, multiple pieces of clothing have to be packed in the same container, which further causes the following problems: First, since the clothing is stacked in the container, it is easy to produce wrinkles. If the wrinkles are serious, it must be taken out for flattening before leaving the warehouse. Second, since multiple pieces of clothing are stacked in one container, when the clothing needs to be sorted or shipped out, the container must be opened for rummaging, which is time-consuming and laborious. Third, the work such as flattening and rummaging needs to be completed manually, so the labor cost is also increased.

[0004] Therefore, there is an urgent need for a fixed-shelf-free goods warehousing system that can keep the clothing flat and is easy to automate so as to reduce the labor cost. Correspondingly, there is also an urgent need for related components such as connecting tracks for connecting the conveying tracks in different regions and at different levels in such a fixed-shelf-free goods warehousing system.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the following takes a soft sheet storage system as an example, and specifically describes a connecting track and a fixed-shelf-free storage system of the present invention in combination with embodiments and drawings. Among them, the soft sheet storage system can be a clothing storage system, which uses hanging racks (i.e., clothes hangers) as cargo carriers.

[0034] <Embodiment>

[0035] Figure 1 It is the structural schematic diagram of the fixed-shelf-free storage system in the embodiment of the invention.

[0036] As Figure 1 shown, the fixed-shelf-free storage system 100 includes an inbound device 101, a storage device 102, a sorting device 103, an outbound device 104, and a plurality of connecting parts 105.

[0037] The warehousing device 101 is used to warehouse the hangers carrying clothes. The storage device 102 is used to store (or classify and store) the hangers. The sorting device 103 is used to classify and select the hangers output by the storage device 102. The outbound device 104 is used to outbound (or further classify and outbound) the goods carriers after being sorted by the sorting device 103. A plurality of connecting parts 105 are respectively arranged between these devices, and are used to connect the tracks of these devices so that the hangers can move between different devices through the connecting parts 105.

[0038] In this embodiment, the goods are stored and conveyed in the form of tracks both between and inside each device. Among them, three connecting parts 105 are provided, which are respectively denoted as the inbound-storage connecting part 105a, the storage-sorting connecting part 105b, and the sorting-outbound connecting part 105c. The structures of these three connecting parts 105 are the same. In this embodiment, the inbound-storage connecting part 105a is taken as an example for specific description.

[0039] Figure 2 Yes Figure 1 It is the structure diagram of the inner part of the middle frame A.

[0040] As Figure 2 shown, the goods carrier in this embodiment is a hanger 200, and the hanger 200 includes a hook 201 and a support part for placing clothes (not shown in the figure). The hook 201 has a hanging opening 201a, and the hook 200 is hung on each conveying track through the hanging opening 201a. Although Figure 2 only the structure of the hook 201 is shown in the figure, however, those skilled in the art can know the position of the hanger 200 and the clothes hung on the hanger 200 according to the position of the hook 201.

[0041] The inbound-storage connecting part 105a is connected between the inbound circular track 22 of the inbound device 101 and the storage-in circular track 23 of the storage device 102.

[0042] Figure 3 It is the structure diagram of the connecting part in the embodiment of the present invention.

[0043] As Figure 3 shown, the inbound-storage connecting part 105a includes a connecting track 72, a guiding and transferring member 712, and a turning guiding and connecting member 73.

[0044] The connecting track 72 has two ends, which are the upper-level end 721 and the lower-level end 722 respectively. The upper-level end 721 of the connecting track 72 is connected to the guiding and transferring member 712, and the lower-level end 722 of the connecting track 72 is connected to the turning guiding and connecting member 73.

[0045] Figure 4This is the structural diagram of the connecting track in the embodiment of the present invention. Figure 5 This is the structural diagram of the track body of the connecting track in the embodiment of the present invention. Figure 6 This is the front view of the track body in the embodiment of the present invention.

[0046] As Figures 4 - 6 shown, the connecting track 72 has a track body 55, a mounting portion 51, and two lining strips 52.

[0047] The track body 55 is a straight track section integrally formed by aluminum profiles. The track body 55 includes two side support portions 53 and a top support portion 54.

[0048] The two side support portions 53 are oppositely arranged, and their cross-sections are L-shaped. The included angle between the outer surfaces of the two side support portions 53 is 5.5°. The bottom spacing w1 between the outer surfaces of the two side support portions 53 is 21.3 mm, and the thickness of the two side support portions 53 gradually thickens from top to bottom, that is, the two side walls of the track body 55 gradually thicken from top to bottom, which makes the overall center of gravity of the track body 55 move downward and is more stable in use.

[0049] The two side support portions 53 respectively extend downward from the top support portion 54. Two flanges 553 are respectively arranged on the opposite inner surfaces of the two side support portions 53 and protrude inward. The thickness d2 of the flange 553 is 3.5 mm. Thus, a receiving cavity 552 extending through the length direction of the track body 55 and a through opening 551 communicating with the receiving cavity 552 are formed between the top support portion 54 and the two side support portions 53. The width w2 of the receiving cavity 552 is 16.5 mm. The width w3 of the through opening 551 is 8.2 mm and penetrates vertically downward. It can be seen that the width of the receiving cavity 552 is greater than the width of the through opening 551. The receiving cavity 552 and the through opening 551 form a tubular cavity and a limiting structure inside the track body 55. The tubular cavity can be used to place a cylinder, and the limiting structure can be used to fixedly install other components through bolts and nuts with matching shape and size.

[0050] The top support portion 54 is respectively combined with the top end portions of the two side support portions 53. The thickness d1 of the top support portion 54 is 1.8 mm. The top support portion 54 has two inclined plane portions 541 axially symmetrically distributed along the length direction of the track body 55, and a plane portion 542 located between the two inclined plane portions 541. The supplementary angle α of the included angle between the two inclined plane portions 541 is 40°, that is, the included angle between the two inclined plane portions 541 is 140°.

[0051] The mounting portion 51 is arranged on the top of the track body 55 and is integrally formed with the track body 55. The mounting portion 51 has two mounting grooves 503 and one positioning groove 504.

[0052] The two mounting grooves 503 are respectively arranged on the two inclined surface portions 541 and extend along the length direction of the track body 55. Therefore, the two mounting grooves 503 are also axially symmetrically distributed along the length direction of the track body 55.

[0053] The mounting groove 503 has an abutting surface 5032, an opening 5033 and two inner ends 5031. The abutting surface 5032 is located on the upper surface of the inclined surface portion 541, and the width w4 of the abutting surface 5032 = 5.9 mm. The opening 5033 penetrates upward, and the width w5 of the opening 5033 = 4.7 mm. The width of the opening 5033 is smaller than the width of the abutting surface 5032, thereby forming two inner ends 5031. The two inner ends 5031 are respectively located on both sides of the mounting groove 503, and the height h2 of the inner end 5031 = 1.4 mm.

[0054] The positioning groove 504 is arranged on the flat surface portion 542 and extends along the length direction of the track body 55. The distance h1 from the top of the positioning groove 504, that is, the top of the mounting portion 51 to the bottom of the track body 55 = 23 mm.

[0055] Figure 7 It is a structural diagram of the lining strip in the embodiment of the present invention. Figure 8 It is a front view of the lining strip in the embodiment of the present invention.

[0056] As Figure 7 and Figure 8 shown, the material of the lining strip 52 is PA66 plastic. The cross-section of the lining strip 52 is an inverted U shape, the bottom width w6 = 6 mm, and the height h3 = 6.5 mm. The lining strip 52 has a top 521 and two side walls 522.

[0057] The top 521 is in a semi-circular arc shape, the radius r1 of the outer surface of the semi-circular arc = 2.5 mm, and the radius r2 of the inner surface = 1.25 mm.

[0058] The two side walls 522 are respectively connected to the top 521 and extend downward. The bottom ends of the two side walls 522 respectively have abutting ends 5221 protruding outward. The thickness of the two side walls 522 is 1 mm, and the thickness d3 of the abutting end 5221 = 1.3 mm. As Figure 5 、 Figure 6 and Figure 8 shown, when the lining strip 52 is fitted and installed in the mounting groove 503 of the track body 55, the two abutting ends 5221 respectively abut against the two inner ends 5031.

[0059] A strip through-opening 523 is formed between two side walls 522, and the width w7 of the through-opening 523 is 3.2 mm. Since the material of the strip 52 is a plastic part, the top 521 is semi-circular, and there is a strip through-opening 523, therefore, the strip 52 of this shape has a certain elasticity in the width direction, and the distance between two abutting ends 5221 can be slightly reduced by an external force. The bottom width of the strip 52 is 6 mm, and the width of the abutting surface 5032 of the mounting groove 503 is 5.9 mm. Therefore, during the fitting installation, the distance between two abutting ends 5221 of the strip 52 is reduced by an external force and the strip 52 is fitted and installed into the mounting groove 503. After the fitting installation is completed, the structural restoring force of the strip 52 makes the fitting between the strip 52 and the mounting groove 503 more firm.

[0060] Two strips 52 are respectively fitted and installed in two mounting grooves 503, and the top 521 of the strip 52 protrudes outward from the mounting groove 503, and the height of the strip 52 protruding from the mounting groove 503 is 3.6 mm. Therefore, when the clothes hanger 200 slides on the connecting track 72, the clothes hanger 200 only contacts two strips 52. Since two strips 52 support the clothes hanger 200 at the same time, therefore, the clothes hanger 200 can move stably on the connecting track 72, is not easy to shake, and since the material of the strip 52 is PA66 plastic, the friction coefficient of the outer surface of the strip 52 is small, making the movement of the clothes hanger 200 on it smoother.

[0061] Figure 9 Yes Figure 1 Structural diagrams of different angles inside the middle frame A.

[0062] As Figure 9 As shown, the upper-stage end 721 of the connecting track 72 is connected to the off-track assembly 71 through a guiding transfer member 712, and is further connected to the incoming-storage annular track 22, and the lower-stage end 722 is connected to the carrying track 63 through a turning guiding connecting member 73, and is further connected to the storage-incoming annular track 23.

[0063] The incoming-storage annular track 22 is a closed annular track and is composed of a random conveying type conveying track. In this embodiment, the random conveying type conveying track is a format type conveying track, which includes a plurality of format members 212. The format members 212 are used to carry and convey the clothes hanger 200, the lower part of which is in a "G" shape matching the hook of the clothes hanger 200, and the upper part is a pulley (not shown in the figure) that can be accommodated in the track section of the placing track 211.

[0064] The storage entry circular track 23 is composed of a single-piece conveying type conveying track. In this embodiment, the single-piece conveying type conveying track is a bird hook type conveying track. The bird hook type conveying track includes a plurality of bird hook type conveying units 61, a guide rail 62 and a bearing rail 63. Among them, the bearing rail 63 is used to carry the hanger 200, and its part close to the storage room connection part 105a is linear. The bird hook type conveying unit 61 can hook the hook 201 of the hanger 200, and the guide rail 62 can drive the bird hook type conveying unit 61 to move, and drive the hanger 200 to move on the bearing rail 63 along the length direction of the bearing rail 63.

[0065] Figure 10 1 is a diagram of the connection structure between the connection track and the guide transfer component in an embodiment of the present invention.

[0066] like Figure 10 As shown, the upper end 721 of the connecting track 72 is connected to the off-track assembly 71 through the guide transfer member 712, and is further connected to the storage ring track 22. The hanger 200 on the format member 212 is detached from the format member 212 through the off-track assembly 71, and slides onto the connecting track 72 under the guidance of the guide transfer member 712.

[0067] Figure 11 2 is a structural diagram of a guide transfer component in an embodiment of the present invention.

[0068] like Figures 9 - 11 As shown, the guide transfer member 712 includes a first main guide section 81 , an introduction end portion 82 and a discharge end portion 83 .

[0069] The first main guide section 81 has a certain curvature and can guide the hanger 200 to turn. The first main guide section 81 has an upper portion 811 and a lower portion 812. The cross section of the upper portion 811 is a trapezoidal shape matching the hook shape of the hanger 200, and the cross section of the lower portion 812 is a rectangular shape. The introduction end portion 82 gradually widens along the conveying direction.

[0070] The lead-out end 83 has a support plate 833, a positioning protrusion 832 and two limiting plates 834. The support plate 833 is arranged at the lower portion 812 of the first main guide section 81, extending outward from the lower edge of the lower portion 812, and is provided with a mounting hole 833a; the positioning protrusion 832 is arranged at the upper portion 811 of the first main guide section 81, extending outward from the middle edge of the upper portion 811, and the shape of the positioning protrusion 832 matches the positioning groove 504 of the connecting track 72; the lower ends of the two limiting plates 834 are respectively connected to the support plate 833, and the width between the two limiting plates 834 is equal to the width of the connecting track 72.

[0071] When the upper-stage end 721 of the connecting rail 72 is connected to the leading-out end 83 of the guiding transfer member 712, the lower part of the upper-stage end 721 is placed on the pallet 833, and both sides of the upper-stage end 721 are fixed by two limiting plates 834, and bolts are installed through the mounting holes 833a for fixation. At the same time, the positioning protrusion 832 is embedded in the positioning groove 504 to further strengthen the connection.

[0072] Figure 12 It is the installation structure diagram of the bolt in the connecting rail in the embodiment of the present invention.

[0073] As Figure 11 and Figure 12 shown, the stud of the bolt 41 passes through the mounting hole 833a on the pallet 833 and the through-opening 551 of the connecting rail 72, the tail of the stud is located in the accommodation cavity 552, and the T-shaped nut 42 matching the bolt 41 is arranged in the accommodation cavity 552. The bolt 41 and the T-shaped nut 42 are adapted to the through-opening 551. The diameter of the stud of the bolt 41 is smaller than the width of the through-opening 551, so that the stud can pass through the through-opening 551 and there is no too large gap between the stud and the through-opening 551. The width of the T-shaped nut 42 is larger than the width of the through-opening 551, so that the T-shaped nut 42 can be supported by the two flanges 553 and will not fall out of the through-opening 551.

[0074] When the bolt 41 and the T-shaped nut 42 are tightened, both sides of the T-shaped nut 42 are closely attached to the upper surfaces of the two flanges 553, and the bolt head of the bolt 41 is closely attached to the lower surface of the pallet 833 through the washer 43, thereby fixedly connecting the upper-stage end 721 of the connecting rail 72 and the guiding transfer member 712.

[0075] In addition, there are two guiding protrusions 813 above the guiding transfer member 712. The guiding protrusions 813 extend along the length direction of the guiding transfer member 712, and the guiding protrusions 813 are matched with the settings of the mounting grooves 503 on the track main body 55. Therefore, as Figure 9 and Figure 10 shown, when the guiding transfer member 712 is connected to the connecting rail 72, the two guiding protrusions 811 are respectively aligned with the two lining strips 52. Therefore, the two guiding protrusions 813 and the two lining strips 52 can be connected together to form two continuous tracks, so that the hanger 200 can smoothly slide through the guiding transfer member 712 onto the connecting rail 72.

[0076] Figure 13 It is the connection structure diagram of the connecting rail and the turning guiding connection member in the embodiment of the present invention.

[0077] As Figure 13As shown, the lower-stage end 722 of the connecting track 72 is connected to the carrying track 63 through a turning guide connecting member 73. The clothes hanger 200 slides from the connecting track 72 to the turning guide connecting member 73, turns and slides onto the carrying track 63 under the guidance of the turning guide connecting member 73, and is further hooked by the bird-hook type conveying unit 61 and moves on the storage-in annular track 23.

[0078] Figure 14 It is a structural diagram of the turning guide connecting member in an embodiment of the present invention.

[0079] As Figure 10 、 Figure 13 and Figure 14 shown, the turning guide connecting member 73 includes a second main guide section 91 and two connecting ends 92.

[0080] The second main guide section 91 is bent in the length direction, so it can guide the clothes hanger 200 to turn. The second main guide section 91 has an upper part 911 and a lower part 912. The cross-section of the upper part 911 is in a trapezoidal shape matching the hook shape of the clothes hanger 200, and the cross-section shape of the lower part 912 is rectangular.

[0081] The two connecting ends 92 are respectively used to connect the connecting track 72 and the carrying track 63, and the structures and dimensions of the two connecting ends 92 are the same.

[0082] The connecting end 92 has a support plate 921, a positioning convex block 922 and two limiting plates 923. Among them, the support plate 921 is arranged on the lower part 912, extends outward from the lower side edge of the lower part 912, and is provided with an installation hole 921a thereon; the positioning convex block 922 is arranged on the upper part 911, extends outward from the middle edge of the upper part 911, and the shape of the positioning convex block 922 matches the positioning groove 504 of the connecting track 72; the lower ends of the two limiting plates 923 are respectively connected to the support plate 921, and the width between the two limiting plates 923 is equal to the width of the connecting track 72.

[0083] When the lower-stage end 722 of the connecting track 72 is connected to the connecting end 92 of the turning guide connecting member 73, the lower part of the lower-stage end 722 is placed on the support plate 921, the two sides of the lower-stage end 722 are fixed by the two limiting plates 923, and bolts are installed through the installation hole 921a for fixation. At the same time, the positioning convex block 922 is embedded in the positioning groove 504 to further strengthen the connection.

[0084] The upper surface of the second main guide section 91 also has two protrusions 913. The top ends of the protrusions 913 are arc-shaped and are consistent with the top shape of the lining strip 52. The protrusions 913 extend along the length direction of the turning guide connecting member 73, and the protrusions 913 match the setting of the installation groove 503 on the track main body 55. Therefore, asFigure 11 and Figure 12 As shown in Figure 12 , when the turning guide connection member 73 is connected to the connection track 72, the two protrusions 913 are also aligned with the two lining strips 52 respectively. Therefore, the two protrusions 913 and the two lining strips 52 can be connected together to form two continuous tracks, enabling the clothes hanger 200 to smoothly slide from the connection track 72 onto the turning guide connection member 73 and, after being guided by the turning guide connection member 73, turn and slide onto the bearing track 63.

[0085] Functions and effects of the embodiment

[0086] According to the connection track 72 and the fixed - free shelf storage system 100 involved in the present invention, the connection track 72 has a track main body 55, and thus can carry the clothes hanger 200. The track main body 55 has a mounting portion 51 provided at the top. The mounting portion 51 has a mounting groove 503 extending along the length direction of the track main body 55. This mounting groove 503 is used for fitting and mounting the lining strip 52, and the bottom of the lining strip 52 abuts against the mounting groove 503. The top 521 of the lining strip 52 protrudes outward from the mounting groove. Therefore, the lining strip 52 can be stably mounted in the mounting groove 503 and will not be displaced due to force. And when the clothes hanger 200 moves on the connection track 72, the lining strip 52 can support the clothes hanger 200. Since the track main body 55 also has a receiving portion, the receiving portion has a receiving cavity 552 and a through - opening 551 that is connected to the receiving cavity and is located at the bottom of the track main body 55, and both the receiving cavity 552 and the through - opening 551 extend along the length direction of the track main body 55. Therefore, the lower part of the track main body 55 can be embedded and installed with bolts 41 and T - nuts 42 that are adapted to the through - opening 551 through the through - opening 551, without the need for additional operations such as drilling and grooving, which is very convenient. The receiving cavity 552 inside the track main body 55 can be used to place structures such as driving cylinders. At the same time, such a structural design is also beneficial to reducing the self - weight of the track main body 55. In addition, since the track main body 55 and the mounting portion 51 of the connection track 72 are integrally formed, they are easy to process and also convenient for disassembly and replacement.

[0087] Specifically, the track body 55 has two side support portions 53 and a top support portion 54 respectively combined with the top end portions of the two side support portions 53. The top support portion 54 has two symmetrically distributed inclined plane portions 541 and a flat plane portion 542 located between the two inclined plane portions 541. Two mounting grooves 503 are respectively provided on the two inclined plane portions 541. Therefore, the two mounting grooves 503 and the two lining strips 52 respectively installed in the two mounting grooves 503 are also axially symmetrically distributed along the length direction of the track body 55. The top 521 of the lining strip 52 protrudes outward from the mounting groove 503, and the protruding height is 3.6 mm. Therefore, the two symmetrically distributed lining strips 52 can simultaneously support the clothes hanger 200, so that the clothes hanger 200 is not prone to shaking when moving on the connecting track 72.

[0088] Furthermore, the lining strip 52 has two abutting ends 5221, and the mounting groove 503 has two inner end portions 5031 matching the abutting ends 5221. Therefore, the lining strip 52 can be stably installed in the mounting groove 503 and will not be displaced due to force. The shape of the top 521 of the lining strip 52 is semi-circular, and the material of the lining strip 52 is PA66 plastic, which has a low friction coefficient. Therefore, the clothes hanger 200 moves very smoothly on the connecting track 72.

[0089] In addition, the two side support portions 53 respectively extend downward from the top support portion 54, and the lower ends of the side support portions 53 have flanges 553 protruding inward. Therefore, a receiving cavity 552 penetrating along the length direction of the track body 55 and a through opening 551 communicating with the receiving cavity 552 are formed between the top support portion 54 and the two side support portions 53.

[0090] In addition, the upper-stage end portion 721 of the connecting track 72 is connected to the off-track assembly 71 through the guiding transfer member 712 and further connected to the in-warehouse annular track 22. The guiding transfer member 712 has a leading-out end portion 83. The leading-out end portion 83 has a tray 833, a positioning projection 832, and two limiting plates 834. Therefore, when the upper-stage end portion 721 of the connecting track 72 is connected to the leading-out end portion 83 of the guiding transfer member 71, the upper-stage end portion 721 can be fixed by the tray 833 and the limiting plates 834, and the positioning projection 832 is embedded in the positioning groove 504 to further strengthen the connection. At the same time, the two guiding projections 813 above the guiding transfer member 712 are respectively aligned with the two lining strips 52, and the two guiding projections 813 are respectively connected to the two lining strips 52 to form a continuous track, so that the clothes hanger 200 can smoothly slide from the guiding transfer member 712 onto the connecting track 72.

[0091] In addition, the lower-stage end 722 of the connecting track 72 is connected to the carrying track 63 through the turning guide connecting member 73 and further connected to the annular track 23 for storing incoming items. The turning guide connecting member 73 has a connecting end 92. The connecting end 92 has a pallet 921, a positioning bump 922, and two limiting plates 923. Therefore, when the lower-stage end 722 of the connecting track 72 is connected to the connecting end 92 of the turning guide connecting member 73, the lower-stage end 722 can be fixed by the pallet 921 and the limiting plates 923, and the positioning bump 922 is embedded in the positioning groove 504 to further strengthen the connection. At the same time, the two protrusions 913 above the turning guide connecting member 73 are respectively aligned with the two lining strips 52, and the two protrusions 913 are respectively connected to the two lining strips 52 to form a continuous track, enabling the clothes hanger 200 to smoothly slide from the connecting track 72 onto the turning guide connecting member 73.

[0092] Furthermore, since the fixed-shelf-free warehousing system 100 provided by the present invention uses a track form for conveying and storing, there is no need to erect shelves, nor to equip conveying devices such as stackers and shuttle cars, which is easy to build and has a low cost.

[0093] The above embodiments are only used to illustrate the specific embodiments of the present invention, and the present invention is not limited to the description scope of the above embodiments.
