The turning supporting plate 921B is arranged on the lower portion 912, extends outwards from the lower side edge of the lower portion 912, and is provided with a turning mounting hole 924B; corner locating tabs 922B are provided on the upper portion 911 and extend outwardly from the edge at the middle of the upper portion 911.

The track structure of the carrying track 63 is the same as that of the connecting track 72, and the difference between the two is only in the arrangement of the tracks. The carrier rails 63 are thus likewise provided with two underwires 108a, 108b at the top, and a positioning slot, designated carrier positioning slot 108c, provided between the underwires 108a and 108 b.

The lower-stage end 722 of the connecting rail 72 is placed on the corner blade 921A of the upstream connecting end 92A of the corner guide connecting member 73 and is bolted to the bottom of the connecting rail 72 through the corner mounting hole 924 a. Meanwhile, two sides of the next-stage end portion 722 are also abutted against the two turning limiting plates 923A, and the connecting positioning groove 504 is connected with the turning positioning lug 922A in an embedded manner.

The first end 63a of the bearing rail 63 is placed on the corner bracket 921B of the downstream connecting end 92B of the corner guide joining member 73, and the bottom thereof is bolted to the corner mounting hole 924B of the corner guide joining member 73. Meanwhile, two sides of the first end 63a are also abutted against the two turning limiting plates 923B, and the bearing positioning groove 108c is connected with the turning positioning lug 922B in an embedded manner.

Furthermore, the two underwires 108a, 108b of the carrier rail 63 are of the same shape as the projections 911a, 911b of the second main guide section 91 and the two underwires 52a, 52b of the connecting rail 72, and when the carrier rail 63 and the connecting rail 72 are connected to the corner guide connecting member 73, the two underwires 108a, 108b are aligned with the two guide projections 811, respectively, and the two guide projections 811 are also aligned with the two underwires 52a, 52b, respectively, to form a continuous strip-like holding structure.

As shown in fig. 3 to 5, the magazine entrance-side joining track segment 65 is divided into a next-stage upstream track segment portion 651a and a next-stage downstream track segment portion 651b in the conveying direction D4 with reference to the position of the turn guide joining member 73. Accordingly, the carrying rail 63 corresponding to the entry-side connecting rail segment 213 is divided into an upstream carrying rail segment portion 632a corresponding to the next-stage upstream rail segment portion 651a and a downstream carrying rail segment portion 632b corresponding to the next-stage downstream rail segment portion 651 b. The bottom end of upstream bearing track segment portion 632a is second end 63b, the top end of downstream bearing track segment portion 632b is first end 63a, and second end 63b is above first end 63 a.

As above, since the upper stage upstream track segment portion 213a is positioned higher than the movable derailing assembly 71, the movable derailing assembly 71 is positioned higher than the corner guide connecting member 73, the connecting track 72 is obliquely connected to the movable derailing assembly 71 and the corner guide connecting member 73, the corner guide connecting member 73 is positioned higher than the downstream bearing track segment portion 632b, the hangers 200 conveyed to the upstream rail segment portion 213a of the upper stage can depend on gravity and are guided out by the movable derailing assembly 71, still relying on gravity alone, can slide down the connecting track 72, guided by the turn-guiding connecting member 73, onto the downstream carrier track segment portion 632b of the entry ring track 23, thereby realizing the transfer of the clothes hanger 200 from the circular rail 21 for warehousing to the circular rail 23 for entering, and the transfer process only depends on gravity and does not need additional driving force. The hanger 200 hangs with the opening 201a facing out of the loop of the circular track 23 for entry as it rides on the downstream carrier track section 632 b.

The bird hook type conveying unit 61 is used for driving the clothes rack 200 to move on the bearing rail 63. The guide rails 62 are arranged in a loop for guiding the moving direction of the bird hook conveyor unit 61. In this embodiment, a plurality of bird hook conveyor units 61 are continuously distributed on the guide rail 62, and both constitute a bird hook closed loop mounting rail.

Thus, the entrance endless track 23 can convey the clothes hanger 200 in the direction indicated by the arrow D4 in fig. 3. In the following description, the front and rear directions refer to the front and rear directions in the conveyance direction D4, the left and right directions refer to the left and right directions when facing the conveyance direction D4 (i.e., the direction facing D4), and the up and down directions refer to the up and down directions when actually mounted.

FIG. 9 is a schematic illustration of a plurality of bird hook conveyor units coupled together in an embodiment of the present invention; FIG. 10 is an exploded view of an embodiment of a bird hook conveyor unit in accordance with the present invention;

as shown in fig. 9 and 10, the bird hook conveyor unit 61 includes a bird hook 11, a bird hook base 12, a restoring member 13, a connecting member 14, and a moving member 15.

The bird hook 11 includes a bird hook body 111, a pull groove 111a provided in the rear portion of the bird hook body 111, and a shaft hole 112, a stopper hole 113, and an accommodation hole 114 provided in the front portion of the bird hook body 111.

The length direction of the bird hook 111 is substantially the same as the conveying direction D1, and the length is 140 mm. In addition, the front lower edge of the bird hook body 111 is a slanted edge that gradually inclines backward from top to bottom.

The pull groove 111a is used for hooking the hook of the hanger 200, and has a shape corresponding to the hook.

The shaft hole 112 is a circular hole that penetrates the bird hook body 111 in the left-right direction, and is located closer to the end edge of the bird hook 11 than the stopper hole 113. The stopper hole 113 is an elliptical hole that penetrates the bird hook body 111 in the left-right direction, and the long axis direction of the elliptical shape is substantially the same as the up-down direction. The receiving hole 114 extends inward from the top surface of the bird hook body 111 in a direction that coincides with the long axis direction of the stopper hole 113.

The bird hook base 12 of the present embodiment is used for mounting the bird hook 11, and has a bar-shaped base body 121, a mounting portion, and two connecting ends 122.

Wherein, the pedestal 121 is strip-shaped, and its length direction is unanimous with fore-and-aft direction, and specific length is 200 mm. The mounting portion includes two mounting plates 123 extending downward from both sides of the bottom of the housing 121. Four mounting holes 124 are formed in each mounting plate 123, and meanwhile the mounting holes 124 in the two mounting plates 123 are arranged oppositely, namely four pairs of mounting holes 124 are formed in the two mounting plates 123.

The bird hook 11 is mounted through the two pairs of mounting holes 124 in the front. Specifically, when the bird hook 11 is mounted with the bird hook base 12, the shaft hole 112 is hinged to the front one of the two pairs of mounting holes 124 through the rotating shaft 125, so that the body 111 can rotate around the shaft hole 112. Meanwhile, two limiting columns (not shown in the figure) are respectively and fixedly installed on the more rear pair of the two pairs of mounting holes 124, and the end portions of the limiting columns extend inwards to extend into the limiting holes 113, so that the rotation degree of the bird hook body 111 is limited. That is, the pivotal movement of the bird hook 11 is restricted to the positions corresponding to both ends of the stopper hole 113 in the longitudinal direction.

The return member 13 is a spring, one end of which is fixed to the bottom surface of the seat body 121 at a position between the two mounting plates 123 and the other end of which abuts against the bottom of the accommodation hole 114. The return element 13 provides a downward force to the bird hook body 11 by its spring force, whereby the bird hook body 11, when not subjected to an external force, abuts against the underlying carrier rail 63 by the spring force of the return element 13.

When the hanger 200 enters the carrying rail 63 from the connecting rail 105, once the bird hook 11 moves forward from the rear side of the hanger 200, the hanger 200 hook will abut against the front lower edge of the bird hook body 111; since the lower edge of the front portion of the bird hook body 111 is a beveled edge that gradually inclines from top to bottom, the bird hook body 111 does not drive the clothes hanger 200 to move forward, but can tilt upward around the shaft hole 112 (i.e., the end where the pulling groove 111a is located tilts upward). When the bird hook 11 continues to move forward and the pull groove 111a reaches the clothes rack 200 and no other clothes rack 200 exists on the bearing rail 63 at the lower side of the bird hook body 111, the spring force of the reset piece 13 makes the bird hook 11 rotate downward, so that the hook of the clothes rack 200 is hooked by the pull groove 111a, and the bird hook 11 can move forward under the pull. In addition, since the size of the pull-out groove 111a matches the size of the hook of the hanger 200, it can only catch one hanger 200 at a time and pull it forward, and the hanger 200 which is not pulled away will remain in place to be pulled away by the next bird hook 11.

The two connecting ends 122 are respectively located at the front and rear ends of the seat body 121, and are respectively used for connecting two bird hook seats 12 adjacent to the bird hook seat 12 in the conveying direction. Wherein, the connecting end 122 located at the front end of the seat body 121 is marked as a front connecting end 122A, and the connecting end 122 located at the rear end of the seat body 121 is marked as a rear connecting end 122B.

Front connection end 122A has two front end connecting plates 1221A, and these two front end connecting plates 1221A set up side by side along the up-down direction, and the two are equipped with front end connecting hole 1222A that runs through along the up-down direction.

Rear connection end 122B has two rear end connecting plates 1221B, and these two rear end connecting plates 1221B set up side by side along the left-right direction, and the two all are equipped with the rear end connecting hole 1222B that runs through along the left-right direction.

When a plurality of bird hook conveying units 61 are connected in sequence, the bird hook seats 12 of two adjacent bird hook conveying units 61 are connected by the connecting member 14. Meanwhile, the moving assembly 15 is also provided at the connecting member 62.

The connection member 14 is disposed at the front connection end 122A and includes a front end coupling plate 141 and a rear end coupling plate 142. The front end coupling plate 141 is provided with a front end coupling hole 143, the rear end coupling plate 142 is provided with a rear end coupling hole 144, and the center line directions of the front end coupling hole 143 and the rear end coupling hole 144 are perpendicular to each other.

The moving member 15 is provided at the front connection end 12A of the bird hook base 12, and includes a roller frame 151 and a roller assembly mounted on the roller frame 151. Wherein, the bottom end of the roller frame 151 is provided with a central through shaft 152 extending downwards, and the bottom end of the central through shaft 152 is provided with an external thread.

When two adjacent bird hook conveying units 61 are connected, the front connecting end 122A of the next bird hook conveying unit 61 is connected to the rear connecting end 122B of the previous bird hook conveying unit 61 via the connecting member 14 and the center through shaft 152.

Specifically, the rear end combination plate 142 extends between two rear end connection plates 1221B of the previous bird hook base 12, and passes through the rear end combination hole 144 and the rear end connection hole 1222B through a connection part such as a bolt and is fixedly connected with a nut, so that the rear end combination plate 142 and the rear connection end 122B can be rotatably connected. Meanwhile, the front end combination plate 141 extends into between two front end connection plates 1221A of the rear bird hook base 12, and the central through shaft 152 sequentially passes through the front end connection hole 1222A on the upper side, the front end combination hole 143, and the front end combination hole 1222B on the lower side and then is in threaded connection with the nut, so that the rotary connection between the front end combination plate 141 and the front connection end 122A is realized.

Since the front end connection holes 1222A penetrate the front end connection plate 1221A in the vertical direction, the front end coupling plate 141 and the front connection end 122A are rotatably connected by the center penetration shaft 152, and the two adjacent bird hook seats 12 can rotate left and right. Since the rear connection holes 1222B penetrate the rear connection plate 1221B in the left-right direction, the two adjacent bird hook seats 12 can rotate up and down by the rotation connection of the rear connection plate 142 and the rear connection end 122B. Therefore, two adjacent bird hook seats 12 can simultaneously rotate left and right and up and down, that is, the relative rotation between the two bird hook seats has two degrees of freedom.

Fig. 11 is a schematic structural diagram of the second driving portion in a state where the moving member is engaged with the guide rail in the embodiment of the present invention.

As shown in fig. 11, the moving member 15 functions to move the bird hook base 12, wherein the roller assembly includes a load bearing roller 153, a moving wheel shaft 154, a guide roller 155, and a guide wheel mounting portion 156.

The movable wheel axle 154 is disposed on the top of the wheel frame 151 and extends in the left-right direction. The number of the bearing rollers 153 is two, and the two bearing rollers are respectively installed on both sides of the movable wheel axle 154, and the central axes of the two bearing rollers are along the left-right direction.

The number of the guide wheel mounting portions 156 is two, and the two guide wheel mounting portions 156 are provided at the middle of the roller frame 151 and arranged in the front-rear direction. The guide rollers 155 are also two in number, and are respectively mounted on the guide roller mounting portions 156 with their axes in the up-down direction.

The lower portion of the guide rail 62 has an opening with inwardly extending bearing flanges 621 on both sides of the opening. The two bearing flanges 621 are distributed on the guide rail 62 in the front-rear direction, and the two bearing rollers 153 are respectively located on the two bearing flanges 621 and can slide on the bearing flanges 621 in the front-rear direction.

The inner sides of the two bearing flanges 621 are respectively provided with a guide flange 622 extending downwards, and the guide roller 155 is located between the two guide flanges 622 and can contact with the guide flanges 622, so that the displacement of the moving member 15 is not easily generated.

The entry endless track 23 of the present embodiment is further provided with a second driving unit 64 for driving the movement of each bird hook conveying unit 61, and the second driving unit 64 includes a driving motor 641, a first driving wheel 642, and a second driving wheel 643.

The driving motor 641 is fixedly mounted near the guide rail 62 (in fig. 11, the mounting bracket and the like are omitted for clarity of the structure).

The first driving wheel 642 and the second driving wheel 643 are respectively installed on both sides of the rail 62, and the central axes of the two are along the vertical direction; meanwhile, the surfaces of the first drive wheel 642 and the second drive wheel 643 respectively abut against the two side surfaces of the bird hook base 12, so that the bird hook base 12 is "sandwiched" from both sides by the first drive wheel 642 and the second drive wheel 643. The first driving wheel 642 is connected to an output shaft of the driving motor 641 through a transmission mechanism, and can rotate under the driving of the driving motor 641, when the first driving wheel 642 rotates, the bird hook base 12 in contact therewith is driven to move by friction, and when the next bird hook base 12 moves, the next bird hook base continues to abut against the first driving wheel 642, so that the next bird hook base continues to be driven to move by the first driving wheel 642. During the movement, the second driving wheel 643 abuts against the bird hook base 12 from the opposite side of the first driving wheel 642, and is rotated together by the friction force of the bird hook base 12, thereby stabilizing the bird hook base 12.

In this embodiment, since the moving member 15 is coupled to the connecting member 14 through the central through shaft 152, and the connecting member 14 connects two adjacent bird hook bases 12, when each of the bearing rollers 153 is driven by the second driving portion 64 to move forward, each of the bird hook bases 12 is driven to move forward, and the bird hook 11 is driven to move forward, so that the clothes hanger 200 can be hooked and pulled forward. The first driving unit has the same structure as the second driving unit 64.

The structure of the delivery endless track 24 is the same as that of the warehousing endless track 21, and is also a format type conveying track, and therefore, it will not be described in detail. The stock line 25 and the return rail 29 are provided between the entry endless rail 23 and the exit endless rail 24.

As shown in fig. 13, a plurality of notches 631 are provided in the carrier rail 63 of the entry ring rail 23. The bearing track 63 has a notch front end 6311 and a notch rear end 6312 corresponding to each notch 631, wherein the notch front end 6311 is located in front of the notch 631 and the notch rear end 6312 is located behind the notch 631.

The number of the storage lines 25 is the same as the number of the diversion assemblies 26 and the number of the notches 631, and the three are arranged in a one-to-one correspondence. A plurality of storage lines 25 are disposed substantially in parallel between the entry endless track 23 and the exit endless track 24. The storage line 25 has a strip-shaped guide rail and is formed by another bird-hook type conveying track, which is denoted as a second bird-hook type conveying track. The second bird hook type conveying track is a bird hook type conveying track in the prior art, and comprises a second bird hook 251 and a hanger rail 252 arranged below the second bird hook 251 and used for bearing a hanger 200, wherein the working principle of the second bird hook 251 is the same as that of the bird hook 11, and a bird hook driving part (not shown in the figure) is further arranged on the second bird hook type conveying track, and the bird hook driving part is of a motor-driven and chain-driven structure in the prior art. The hanger rail 252 is of the same construction as the connecting rail 72, is disposed on one side of the strip track, and has an upstream storage end 2521 and a downstream storage end 2522.

As shown in fig. 12 and 16, the guide unit 27 includes a storage guide connecting member 271 and a storage connecting rail 272. The storage guide coupling member 271 and the turn guide coupling member 73 have the same structure, and the storage coupling rail 272 and the hanger rail 252 have the same structure. The storage guide coupling member 271 has one end coupled to the downstream storage end 2522 of the hanger rail 252 and the other end coupled to one end of the storage coupling rail 272. The other end of the connecting rail 272 is formed in a pointed shape and its pointed edge is disposed above the format member 212 'of the "G" type of the discharging endless rail 24 for guiding the hanger 200 into the format member 212'. In addition, the hanger rail 252 is positioned higher than the format member 212', and the entire guide assembly 27 is disposed obliquely in the vertical direction, so that the hanger 200 can freely slide down along the guide assembly 27 onto the discharging circular rail 24 under the self-gravity.

As shown in fig. 12 and 16, the number of the blocking assemblies 28 is the same as the number of the stocker lines 25, and the plurality of blocking assemblies 28 are disposed on the plurality of stocker lines 25 in a one-to-one correspondence. Specifically, the blocking assembly 28 is disposed on the storage line 25 proximate the downstream storage end 2522. The blocking assembly 28 has a motor driven lever 281. When the stop lever 281 is in the blocking position shown in fig. 15, the stop lever 281 is transversely arranged on the hanger rail 252, when the second bird hook 251 hooks the hanger 200 and passes through the stop lever 281, the front part of the second bird hook 251 is blocked by the stop lever 281 to be lifted upwards, and the hanger 200 is not dragged by the rear part of the second bird hook 251 and stays on the hanger rail 252; when the lever 281 is out of the blocking position, the clothes hanger 200 can smoothly enter the output circular rail 24 via the guide member 27.

As shown in fig. 12, the return rail 29 is for returning the hanger 200 on the outgoing endless rail 24 to the incoming endless rail 23, and has a downstream return end 291 and an upstream return end 292. The downstream return end 291 is close to the output endless track 24, and the upstream return end 292 is close to the entrance endless track 23.

The downstream return end 291 is provided with a return derailing unit 293 having the same structure as the movable derailing unit 71, and is connected to the output endless track 24 via the return derailing unit 293. Further, a code reader corresponding to the return off-rail assembly 293 is provided on the output endless rail 24, and the code reader is provided upstream of a portion of the output endless rail 24 corresponding to the return off-rail assembly 293, for reading a code of the passing hanger 200, thereby indicating whether or not the return off-rail assembly 293 allows the hanger 200 to enter the return rail 29.

The upstream return end portion 292 is provided with a return curved guide connecting member 294, which is connected to the entry endless track 23 via the return curved guide connecting member 294, and which has the same structure as the curved guide connecting member 73.

In the present embodiment, the return rail 29 is substantially parallel to the storage line 25, and the portion of the output endless rail 24 connected to the downstream return end 291 is located upstream of the portion of the output endless rail 24 connected to the storage line 25, and the portion of the entry endless rail 23 connected to the upstream return end 292 is located upstream of the notch 631.

The return rail 29 is further provided with a return driving portion (not shown) for driving the hanger 200 to perform a return movement along the return rail 29 (the direction of the return movement is indicated by a dotted arrow in fig. 12). The structure of the return driving part is the same as that of the bird hook driving part, and is the prior art, and is not described herein again.

The output endless track 24 is used to guide the hangers 200 on the magazine line 25 to be output from the first stocker 102 a. The outgoing endless track 24 may also guide the hangers 200 on the magazine line 25 back to the incoming endless track 23 via the return track 29 for re-delivery to the other magazine lines 25 of the first stocker 102 a.

As shown in fig. 1, the second stocker 102b has substantially the same structure as the first stocker 102a, except that the number of the stocker lines 25 of the two apparatuses is different, and the other structures are completely the same. The first stocker 102a is the stocker 102 located most upstream in the conveying direction of the hangers 200, and the stocker lines 25 thereof are arranged at 50 to 80, preferably 60. The number of the stocker lines 25 of the second stocker 102b is 15 to 30, preferably 20. The second stocker 102b is used to sort and store the hangers 200 received from the first stocker 102 a.

The entrance circular rail 23 of the second stocker 102b is connected to the exit circular rail 24 of the first stocker 102a by the second connection portion 105 b. The second connection portion 105b has the same structure as the first connection portion 105a, the second connection portion 105b and the circular track 23 for entry of the second stocker 102b are connected in the same manner as the first connection portion 105a and the circular track 23 for entry of the first stocker 102b, and the second connection portion 105b and the circular track 24 for output of the first stocker 102a are connected in the same manner as the first connection portion 105a and the circular track 21 for warehousing. The second connection portion 105b functions to guide the hangers 200 on the outgoing circular rail 24 of the first stocker 102a to freely move to the incoming circular rail 23 of the second stocker 102b by its own weight.

The delivery device 104 includes a delivery circular rail 30 and a delivery line 31.

The delivery endless track 30 is a bird-hook type conveying track having the same structure as the entry endless track 23. The outgoing endless track 30 is connected to the outgoing endless track 24 of the second stocker 102b via a third connection portion 105 c. The third connection portion 105c has the same structure as the connection portion 105b between the warehousing storage, and the third connection portion 105c and the circular track 23 for output have the same connection manner as the first connection portion 105a and the circular track 23 for entry of the first warehousing equipment 102b, and the third connection portion 105c and the circular track 24 for output of the second warehousing equipment 102b have the same connection manner as the first connection portion 105a and the circular track 21 for warehousing. The third connection portion 105c serves to guide the hangers 200 on the output circular rail 24 of the second stocker 102b to freely move to the delivery circular rail 30 by its own weight.

The delivery line 31 is similar in construction to the storage line 25 and the delivery line 31 is similarly connected to the goods delivery endless track 30 by the same construction as the diverter assembly 26. The unloading line 31 is used for unloading the clothes hangers 200 from the circular track 30 for goods unloading. The number of the ex-warehouse lines 31 is at least one. In the present embodiment, the number of the delivery lines 31 is three, and the purpose of sorting output can be achieved by these three delivery lines 31.

The working principle of the warehouse sorting system 100 without fixed shelves is as follows:

a plurality of clothes hangers 200 are put in storage in sequence by the storage facility 101.

The hangers 200 are then conveyed to the first connecting portion 105a and then respectively enter the corresponding stockers 25 of the first stocker 102a through the plurality of diversion assemblies 26 provided on the entry endless track 23.

When it is desired to store a hanger 200 on the first magazine 102a, the stop lever 281 of the blocking assembly 28 on the magazine line 25 is in the blocking position so that the hanger 200 remains on the magazine line 25.

When it is not necessary to store the clothes hangers 200 in the first stocker 102a, the blocking lever 281 of the blocking assembly 28 is moved out of the blocking position, so that the clothes hangers 200 on the stocker line 25 can be smoothly conveyed to the second stocker 102b through the second connecting portion 105b and then respectively enter the corresponding stocker line 25 of the second stocker 102b through the plurality of diverting assemblies 26 provided on the entering endless track 23 of the second stocker 102 b.

The process of sorted storage and departure of the hangers 200 at the second stocker 102b is the same as the process of sorted storage and departure of the hangers 200 at the first stocker 102 a.

When the hangers 200 in the second stocker 102b enter the unloading facility 104 through the third connecting portion 105c, they enter the corresponding unloading line 31 through the plurality of diverter assemblies provided on the unloading endless track 24, respectively, and are sorted out (sorted out).

In the above process, there may be a case where the wrong magazine line 25 is entered when the clothes hanger 200 enters the stocker 102, and at this time, the clothes hanger 200 may be returned from the feeding endless track 24 to the feeding endless track 23 through the return track 29 to be re-entered into the magazine line 25.

Therefore, the warehousing equipment 102 can not only realize the sorting and storing functions, but also quickly convey and transfer the stored clothes racks 200 to the next warehousing equipment 102 or the ex-warehouse equipment 108. The classification storage process can be automatically realized without manual operation, and the whole equipment does not relate to a fixed goods shelf at all.

Further, since the conveying direction of the entrance endless track 23 is opposite to the conveying direction of the exit endless track 24, and the stocker 102 further includes the return track 29, the return track 29 is provided between the entrance endless track 23 and the exit endless track 24, the hangers 200 on the exit endless track 24 can be returned to the entrance endless track 23. Therefore, once the sorting and storage problems occur in the storage line, the clothes hangers 200 can be returned to the entering circular rail 23 through the output circular rail 24 and the return circular rail 29, and then the storage line 25 is re-entered to realize the sorting and storage, so that the sorting accuracy of each storage device 102 is ensured, and the sorting and storage level of the whole storage system 100 without the fixed shelves is improved.

In addition, because the non-fixed-rack warehousing and sorting system 100 of the embodiment adopts a rail form for conveying and storing, fixed racks do not need to be erected, conveying equipment such as a stacker and a shuttle vehicle does not need to be equipped, and the non-fixed-rack warehousing and sorting system is easy to construct and low in cost.

Further, since the return rail 29 has a downstream return end portion 291 and an upstream return end portion 292, the downstream return end portion 291 is provided with a return off-rail assembly 293 and connected to the output endless rail 24 via the return off-rail assembly 293, and the upstream return end portion 292 is provided with a return turn guide connecting member 294 and connected to the entry endless rail 23 via the return turn guide connecting member 294. The hangers 200 on the outgoing endless track 24 can be returned to the incoming endless track 23 through the return track 29. Further, since the incoming circular rail 23 has the carrying rail 63 carrying the hangers 200, and the stocker 102 further has a plurality of diverting assemblies 26 corresponding to the plurality of stocker lines 25 one by one, the diverting assemblies 26 are disposed on the corresponding stocker lines 25 and incoming circular rail 23, the hangers 200 on the incoming circular rail 23 can be guided to different stocker lines 25 by the plurality of diverting assemblies 26 to be sorted and stored.

Further, since the return rail 29 is also provided with a return movement driving part for driving the hanger 200 to perform the return movement, the return movement driving part can drive the hanger 200 to perform the return movement on the return rail 29. The magazine line 25 is further provided with a blocking assembly 28, and the blocking assembly 28 can control whether the clothes hangers 200 on the magazine line 25 enter the circular track 24 for output.

Since the output endless track 24 is constituted by a format type conveying track, the purpose of random conveyance can be well achieved; since the entry endless track 23 is constituted by a bird-hook type conveying track, the object of single piece conveying can be well achieved. Since the conveying direction of the outgoing endless track 24 is opposite to the conveying direction of the incoming endless track 23, the hanging opening 201a of the hook 201 on the outgoing endless track 24 faces the inside of the outgoing endless track 24, and the hanging opening 201a of the hook 201 on the incoming endless track 23 faces the outside of the inside of the incoming endless track 23, the hanger 200 can be smoothly transferred from the outgoing endless track 24 of the one-stage stocker 102 to the incoming endless track 23 of the next-stage stocker 102 and conveyed.

In addition, since the non-fixed rack warehousing sorting system 100 further includes the warehousing equipment 101, the ex-warehouse equipment 104 and a plurality of connecting parts 105, and the warehousing equipment 101 and the first warehousing equipment 102a, the first warehousing equipment 102a and the second warehousing equipment 102b, and the second warehousing equipment 102b and the ex-warehouse equipment 104 are connected through the connecting parts 105, the movement of the hanger 200 between the two corresponding equipments can be smoothly realized through the connecting parts 105.

Further, since the one-piece conveying type conveying rail (the entry endless rail 23, the exit endless rail 30) has the carrying rail 63 carrying the hangers 200, the connecting rail 72 has the upper stage end portion 721 and the lower stage end portion 722, the upper stage end portion 721 is connected to the corresponding random conveying type conveying rail (the entry endless rail 21, the exit endless rail 24) by the movable off-rail assembly 71, and the lower stage end portion 722 is connected to the carrying rail 63 by the turn guide connecting member 73, the hangers 200 on the random conveying type conveying rail can be easily transferred to the carrying rail 63 of the lower stage conveying rail (for example, the) by the movable off-rail assembly 71, the connecting rail 72, and the turn guide connecting member 73.

Further, since the endless track 24 for output has the upstream-stage upstream track segment portion 213a which is upstream in the conveying direction D1 of the hanger 200 and the downstream-stage upstream track segment portion 213b which is downstream from the corresponding movable off-track assembly 71, the upstream-stage upstream track segment portion 213a is higher than the downstream-stage downstream track segment portion 213b, the hanger 200 conveyed to the upstream-stage upstream track segment portion 213a in the conveying direction D1 can be guided by the movable off-track assembly 71 to exit the upstream-stage upstream track segment portion 213a by its own weight.

Further, since the entry endless track 23 has the next-stage upstream track segment portion 651a and the next-stage downstream track segment portion 651b which are upstream and downstream in the conveying direction D4 of the hanger 200 as compared with the curve guide linking member 73, the next-stage upstream track segment portion 651a is higher than the next-stage downstream track segment portion 651b, the movable derailing assembly 71 is higher than the curve guide linking member 73, therefore, the clothes hanger 200 guided by the movable derailing assembly 71 can still slide down along the connecting rail 72 by gravity only and be guided by the turn guide connecting member 73, enters the next-stage downstream track segment portion 651b of the first entering endless track 23a, thereby, the transfer of the clothes hanger 200 from the first discharging endless track 24a to the first entering endless track 23a is achieved, and the transfer process is dependent on only gravity and does not require additional driving force.

The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.

For example, in the present embodiment, the number of the stockers 102 is two, and in actual use, the number of the stockers 102 may be one, that is, only the first stocker 102a is provided, and in this case, the output circular track 24 of the first stocker 102a is directly connected to the ex-warehouse 104 through the connection portion 105. In addition, in practical use, the number of the warehousing equipment 102 may be set to be more than two, wherein the warehousing lines 25 of the warehousing equipment 102 located at the most upstream are set to be 50 to 80, the number of the rest warehousing equipment 102 is set to be 15 to 30, and the number of the rest warehousing equipment 102 may be the same or different from each other.
