Description

Technical Field

[0001] The present invention belongs to the field of goods storage, and particularly relates to a bird hook type conveying unit, a bird hook type closed-loop installation track containing the bird hook type conveying unit, and a goods storage system. Background Art

[0002] Existing goods storage systems generally adopt the method of combining storage bins with shelves to achieve goods storage, and use conveying equipment such as stacker cranes and shuttle cars to convey goods between different storage modules in the storage system.

[0003] The above-mentioned goods storage system has problems such as cumbersome construction of shelves and high costs of shelves and conveying equipment. In addition, when such a goods storage system is applied to industries where goods are in the form of soft sheets, such as the clothing industry, since multiple pieces of clothing have to be packed in the same storage bin during the conveying and storage processes, the clothing is prone to wrinkling in the storage bin, and when the wrinkling is severe, it needs to be flattened before leaving the warehouse. Moreover, since single-piece storage and single-piece conveying cannot be achieved, once it is necessary to re-sort or classify and store the clothing according to its attributes, the storage bin needs to be opened, and then manually rummaged through and sorted, which is very inconvenient and not conducive to automation, resulting in high labor costs.

[0004] Therefore, a fixed-shelf-free goods storage system that does not require the construction of shelves, can avoid the stacking of clothing, and is easy to achieve single-piece storage and conveying, thereby facilitating automation and reducing labor costs, has become an urgent need at present. Among them, if single-piece conveying can be achieved in the storage system, it can not only prevent the mutual stacking and extrusion of clothing, but also facilitate sorting or classified storage according to different attributes. Therefore, there is an especially urgent need for a conveying mechanism that can effectively achieve single-piece conveying. Summary of the Invention

Detailed implementation manner

[0034] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the following takes a flexible sheet material storage system as an example, and specifically describes a guiding transfer member and a goods storage system of the present invention in conjunction with the drawings. Among them, the flexible sheet material storage system can be a clothing storage system, which uses a hanging rack (i.e., a hanger) as a goods carrier.

[0035] Embodiment

[0036] Figure 1 is a schematic structural diagram of the goods storage system in this embodiment.

[0037] As Figure 1 shown, the goods storage system 100 of this embodiment is a fixed-shelf-free storage system that uses tracks to convey and store goods carriers carrying goods, and includes an inbound module 101, a storage module 102, a sorting module 103, an outbound module 104, and multiple connecting tracks 105.

[0038] The inbound module 101 is used to put the goods carrier into storage, the storage module 102 is used to store (or classify and store) the goods carrier, the sorting module 103 is used to classify and select the goods carrier output by the storage module 102, and the outbound module 104 is used to take the goods carrier sorted by the sorting module 103 out of storage (or further classify and take it out of storage).

[0039] In this embodiment, the number of connecting tracks 105 is three, which are respectively arranged between the warehousing module 101 and the storage module 102, between the storage module 102 and the sorting module 103, and between the sorting module 103 and the outbound module 104, and are used to connect the tracks of these modules so that the goods carrier can move between different modules through the connecting tracks.

[0040] Among them, the storage module 102 includes a storage receiving track 106 and multiple storage tracks 107. The storage tracks 106 are all linear, and the storage tracks 106 are arranged side by side, and are used to store the goods carrier. The storage receiving track 106 is annular, and is used to receive the goods carrier from the warehousing module 101 and convey these goods carriers to different storage tracks 107 for storage. Thus, the storage module 102 has the ability to achieve classified storage (that is, the goods carriers carrying different types of goods can be conveyed to different storage tracks 107 according to needs). In addition, it can also be seen from Figure 1 that the sorting module 103 and the outbound module 104 also have a structure combining an annular track and a linear track, and the annular track located upstream of the linear track also plays a role in conveying the goods carrier to different linear tracks; correspondingly, the functions of classified picking and classified outbound can be realized.

[0041] That is to say, in this embodiment, there are multiple conveying tracks for conveying the goods carrier to different linear tracks, and these conveying tracks are all annular. In this embodiment, these annular conveying tracks for conveying the goods carrier to different linear tracks are bird-hook type conveying tracks. The following takes Figure 1 the part inside frame A (that is, a section of the storage receiving track 106) as an example for specific description.

[0042] Figure 2 is Figure 1 the structure diagram of the part inside frame A.

[0043] As Figure 2 shown, the storage receiving track 106 is used to convey the clothes hanger 200 as a goods carrier, and includes a plurality of bird-hook type conveying units 61, a guide rail 62, and a bearing track 63.

[0044] Among them, the carrying track 63 has a shape matching the hook of the clothes hanger 200 and is used to carry the clothes hanger 200. In this embodiment, the structure of the connecting track 105 is the same as that of the carrying track 63. The carrying track 63 is set to be non-circular, and its end is connected to the connecting track 105, so that the clothes hanger 200 can be received from the connecting track 105 by the warehousing module 101. In addition, the carrying track 63 is respectively connected to the storage tracks 107 through a plurality of shunting components, so as to introduce the goods carrier into different storage tracks 107 through the shunting components. The shunting components in this embodiment adopt the disconnection or closing track shunting components in the prior art, and will not be elaborated herein specifically.

[0045] The bird hook type conveying unit 61 is used to drive the clothes hanger 200 to move on the carrying track 63. The guide rail 62 is arranged in a ring shape and is used to guide the moving direction of the bird hook type conveying unit 61. In this embodiment, a plurality of bird hook type conveying units 61 are continuously distributed on the guide rail 62, and the two constitute a bird hook type closed-loop installation track.

[0046] Thus, the storage receiving track 106 can realize the conveying of the clothes hanger 200, and its conveying direction is Figure 2 the direction shown by the arrow D1 in the figure. In the following description, the front and rear directions both refer to the front and rear directions in the conveying direction, the left and right directions both refer to the left and right directions when facing the conveying direction (i.e., facing the direction indicated by D1), and the up and down directions both refer to the up and down directions during actual installation.

[0047] Figure 3 is the structural diagram of the bird hook type conveying unit in the embodiment of the present invention, Figure 4 is the exploded structural diagram of the bird hook type conveying unit in the embodiment of the present invention.

[0048] As Figure 3 and Figure 4 shown, the bird hook type conveying unit 61 includes a bird hook 11, a bird hook seat 12, a reset member 13, a connecting member 14, and a moving member 15.

[0049] Figure 5 is the structural diagram of the bird hook in the embodiment of the present invention.

[0050] As Figure 5 shown, the bird hook 11 has a bird hook body 111, a pulling groove 111a arranged at the rear part of the bird hook body 111, and a shaft hole 112, a limiting hole 113, and a receiving hole 114 arranged at the front part of the bird hook body 111.

[0051] Among them, the length direction of the bird hook 111 is basically consistent with the conveying direction D1, and the length is 140 mm. In addition, the lower edge of the front part of the bird hook body 111 is an inclined edge that gradually inclines backward from top to bottom.

[0052] The pulling groove 111a is used to hook the hook of the clothes hanger 200, and its shape is adapted to the hook.

[0053] The shaft hole 112 is a circular hole penetrating the bird hook body 111 in the left - right direction, and is located at a position closer to the end edge of the bird hook 11 than the limit hole 113. The limit hole 113 is an oval hole penetrating the bird hook body 111 in the left - right direction, and the long axis direction of its oval 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, and its extending direction is the same as the long axis direction of the limit hole 113.

[0054] Figure 6 is a perspective view of an angle of the bird hook seat according to an embodiment of the present invention, Figure 7 is a perspective view of another angle of the bird hook seat of the present invention.

[0055] As Figure 3-4 、 Figure 6-7 shown, the bird hook seat 12 of this embodiment is used to install the bird hook 11, and has a seat body 121, a mounting portion, and two connection ends 122.

[0056] Among them, the seat body 121 is strip - shaped, and its length direction is consistent with the front - back direction, and the specific length is 200 mm.

[0057] The mounting portion includes two mounting plates 123 respectively extending downward from both sides of the bottom of the seat body 121. Four mounting holes 124 are provided on each mounting plate 123. At the same time, the mounting holes 124 on the two mounting plates 123 are arranged opposite to each other, that is, a total of four pairs of mounting holes 124 are provided on the two mounting plates 123. In this embodiment, the four pairs of mounting holes 124 are symmetrically distributed with the vertical center line of the seat body 121 in the length direction as the center, and the bird hook 11 is installed through the front two pairs of mounting holes 124.

[0058] Figure 8 is a cross - sectional view of the bird hook and the bird hook seat in the installed state according to an embodiment of the present invention.

[0059] As Figure 3-4 、 Figure 8 shown, when the bird hook 11 is installed with the bird hook seat 12, the shaft hole 112 is hinged to the more forward pair of the front two pairs of mounting holes 124 through the rotating shaft 125, so that the body 111 can rotate around the shaft hole 112. At the same time, two limit posts (not shown in the figure) are respectively fixedly installed on the more rearward pair of the two pairs of mounting holes 124, and the ends of the limit posts extend inward to extend into the limit hole 113, thereby restricting the rotation degree of the bird hook body 111. That is, the rotatable degree of the bird hook 11 is restricted within the positions corresponding to both ends of the long axis direction of the limit hole 113.

[0060] The reset member 13 is a spring, one end of which is fixed at a position between two mounting plates 123 on the bottom surface of the seat body 121, and the other end abuts against the bottom of the receiving hole 114. The reset member 13 provides a downward force to the hook body 11 through its spring force. Thus, when the hook 11 is not subject to an external force, it abuts against the carrying track 63 below it due to the spring force of the reset member 13.

[0061] When the clothes hanger 200 enters the carrying track 63 from the connecting track 105, once the hook 11 moves forward from the rear side of the clothes hanger 200, the hook of the clothes hanger 200 will abut against the lower front edge of the hook body 111; since the lower front edge of the hook body 111 is an inclined edge that gradually inclines backward from top to bottom, the hook body 111 will not drive the clothes hanger 200 to move forward, but will tilt upward around the shaft hole 112 (i.e., the end where the pulling groove 111a is located tilts upward). When the hook 11 continues to move forward, when the pulling groove 111a reaches the clothes hanger 200 and there is no other clothes hanger 200 on the carrying track 63 below the hook body 111, the spring force of the reset member 13 causes the hook 11 to rotate downward, so that the hook of the clothes hanger 200 is hooked by the pulling groove 111a, and thus can be pulled forward by the hook 11. In addition, since the size of the pulling groove 111a matches the hook of the clothes hanger 200, it can only hook one clothes hanger 200 at a time and pull it forward, and the clothes hanger 200 that has not been pulled away will stay in place and be pulled away by the next hook 11.

[0062] As Figure 6 、 Figure 7 shown, the two connecting ends 122 are respectively located at the front and rear ends of the seat body 121, and are respectively used to connect two hook seats 12 adjacent to the hook seat 12 in the conveying direction. Among them, the connecting end 122 located at the front end of the seat body 121 is denoted as the front connecting end 122A, and the connecting end 122 located at the rear end of the seat body 121 is denoted as the rear connecting end 122B.

[0063] The front connecting end 122A has two front connecting plates 1221A, the two front connecting plates 1221A are arranged side by side in the up-down direction, and both are provided with front connecting holes 1222A penetrating in the up-down direction.

[0064] The rear connecting end 122B has two rear connecting plates 1221B, the two rear connecting plates 1221B are arranged side by side in the left-right direction, and both are provided with rear connecting holes 1222B penetrating in the left-right direction.

[0065] Figure 9 is a structural diagram of the sequential connection state of multiple hook conveying units. Figure 9 The carrying track 63 and the guide rail 62 are omitted in

[0066] As Figure 9As shown, when multiple bird hook conveying units 61 are connected in sequence, the bird hook seats 12 in two adjacent bird hook conveying units 61 are connected by a connecting member 14. At the same time, the moving assembly 15 is also arranged at the connecting member 62.

[0067] Figure 10 It is a structural diagram of the connecting member of the present invention.

[0068] As Figure 3-4 、 Figure 9-10 shown, the connecting member 14 is arranged at the front connecting end 122A and includes a front end bonding plate 141 and a rear end bonding plate 142. In this embodiment, the extending directions of the front end bonding plate 141 and the rear end bonding plate 142 are perpendicular to each other. A front end bonding hole 143 is provided on the front end bonding plate 141, and a rear end bonding hole 144 is provided on the rear end bonding plate 142. The center line directions of the front end bonding hole 143 and the rear end bonding hole 144 are also perpendicular to each other. Thus, the front end bonding plate 141 and the front end bonding hole 143 constitute a front end bonding portion for bonding with the front connecting end 122A, and the rear end bonding plate 142 and the rear end bonding hole 144 constitute a rear end bonding portion for bonding with the rear connecting end 122B.

[0069] Figure 11 It is a structural diagram of the moving member of the embodiment of the present invention.

[0070] As Figure 11 shown, the moving member 15 is arranged at the front connecting end 12A of the bird hook seat 12 and includes a roller frame 151 and a roller assembly mounted on the roller frame 151. Among them, the bottom end of the roller frame 151 has a central through shaft 152 extending downward, and the bottom end of the central through shaft 152 has an external thread.

[0071] Figure 12 It is an exploded view of the connection structure of two adjacent bird hook conveying units of the embodiment of the present invention.

[0072] As Figure 9 、 Figure 12 shown, when two adjacent bird hook conveying units 61 are connected, the front connecting end 122A of the latter bird hook conveying unit 61 is connected to the rear connecting end 122B of the former bird hook conveying unit 61 via the connecting member 14 and the central through shaft 152.

[0073] Specifically, the rear end coupling plate 142 extends into the space between the two rear end connection plates 1221B of the previous bird hook seat 12. By passing connection components such as bolts through the rear end coupling holes 144 and the rear end connection holes 1222B and fixedly connecting them with nuts, the rotational connection between the rear end coupling plate 142 and the rear connection end 122B can be achieved. At the same time, the front end coupling plate 141 extends into the space between the two front end connection plates 1221A of the subsequent bird hook seat 12. The central through shaft 152 sequentially passes through the upper front end connection hole 1222A, the front end coupling hole 143, and the lower front end coupling hole 1222B and is threadedly connected with a nut, thereby realizing the rotational connection between the front end coupling plate 141 and the front connection end 122A.

[0074] Since the front end connection holes 1222A penetrate the front end connection plates 1221A in the up and down direction, through the central through shaft 152, the rotational connection between the front end coupling plate 141 and the front connection end 122A enables the adjacent two bird hook seats 12 to rotate left and right. Since the rear end connection holes 1222B penetrate the rear end connection plates 1221B in the left and right direction, through the rotational connection between the rear end coupling plate 142 and the rear connection end 122B, the adjacent two bird hook seats 12 can rotate up and down. Thus, the adjacent two bird hook seats 12 can rotate left and right and up and down simultaneously, that is, the relative rotation between them has two degrees of freedom.

[0075] Figure 13 It is a diagram showing the cooperation state of the moving member and the guide rail in the embodiment of the present invention. Figure 13 In the figure, the bird hook 11, the bird hook seat 12, and the bearing track 63 are omitted.

[0076] As Figure 11 、 Figure 13 shown, the function of the moving member 15 is to move the bird hook seat 12. The roller assembly therein includes a load-bearing roller 153, a moving wheel shaft 154, a guiding roller 155, and a guiding wheel mounting portion 156.

[0077] Among them, the moving wheel shaft 154 is arranged at the top of the roller frame 151 and extends in the left and right direction. The number of load-bearing rollers 153 is two, which are respectively installed on both sides of the moving wheel shaft 154, and the central axes of both are in the left and right direction.

[0078] The number of guiding wheel mounting portions 156 is two, and these two guiding wheel mounting portions 156 are arranged in the middle of the roller frame 151 and in the front and rear direction. The number of guiding rollers 155 is also two, which are respectively installed on the guiding wheel mounting portions 156, and the axes of both are in the up and down direction.

[0079] As Figure 13As shown, the lower part of the guide rail 62 has an opening, and on both sides of the opening, there are load-bearing flanges 621 extending inwards. The two load-bearing flanges 621 are distributed on the guide rail 62 in the front-rear direction, and the two load-bearing rollers 153 are respectively located on the two load-bearing flanges 621 and can slide in the front-rear direction on the load-bearing flanges 621. Thus, the two load-bearing rollers 153 constitute a load-bearing member part that enables the moving member 62 to move forward along the guide rail 62, and the central axes of the two load-bearing rollers 153 form a moving central axis perpendicular to the conveying direction D1.

[0080] On the inner sides of the two load-bearing flanges 621, there are also guide flanges 622 extending downwards respectively. The guide rollers 155 are located between the two guide flanges 622 and can be in contact with the guide flanges 622, so that the moving member 15 is not prone to deviation during movement. Thus, the two guide rollers 155 constitute a guide member part that guides the moving process of the moving member 62. The central axes of both are guide central axes, and the guide central axis is in the up-down direction and is also perpendicular to the conveying direction D1.

[0081] As Figure 2 and Figure 9 shown, in this embodiment, since the moving member 15 is connected to the connecting member 14 through the central through shaft 152, and the connecting member 14 connects two adjacent hook seats 12, when each load-bearing roller 153 moves forward under the drive of the drive mechanism, it drives each hook seat 12 to move forward and makes the hook 11 move forward, so as to be able to hook the clothes hanger 200 and pull it forward.

[0082] Figure 14 It is a structural diagram of the drive device of an embodiment of the present invention.

[0083] As Figure 14 shown, the storage and receiving track 106 of this embodiment further includes a drive device 64 that drives the movement of each hook conveying unit 61. The drive device 64 includes a drive motor 641, a first drive wheel 642, and a second drive wheel 643.

[0084] The drive motor 641 is fixedly installed near the guide rail 62 ( Figure 14 in the figure, for clearly showing the structure, structures such as mounting brackets are omitted).

[0085] The first driving wheel 642 and the second driving wheel 643 are respectively installed on both sides of the guide rail 62, and the central axes of both are along the vertical direction. At the same time, the surfaces of the first driving wheel 642 and the second driving wheel 643 respectively abut against both side surfaces of the hook seat 12, so that the hook seat 12 is "clamped" from both sides by the first driving wheel 642 and the second driving wheel 643. The first driving wheel 642 is connected to the output shaft of the driving motor 641 through a transmission mechanism and can rotate under the drive of the driving motor 641. When the first driving wheel 642 rotates, it drives the hook seat 12 in contact with it to move through friction. When the next hook seat 12 moves, it continues to abut against the first driving wheel 642 and is thus continuously driven by the first driving wheel 642 to move. During the movement, the second driving wheel 643 abuts against the hook seat 12 from the opposite side of the first driving wheel 642 and is driven to rotate together by the friction of the hook seat 12, playing a role in stabilizing the hook seat 12.

[0086] Functions and effects of the embodiment

[0087] According to the hook-type conveying unit 61 provided in this embodiment, since the hook seat 12 has two connection ends 122 in the length direction, and the connecting member 14 is arranged at one of the connection ends 122 and is connected to the hook seat 12 in the adjacent hook-type conveying unit 61, the hook seats 12 with hooks 11 installed can be connected in sequence, so that the hooks 11 are arranged at a predetermined interval (i.e., the interval corresponding to the length of the hook seat 12) in the conveying direction in sequence. Thus, the hook-type installation track containing the hook-type conveying unit 11 of this embodiment can convey the clothes hangers 200 individually at a predetermined interval. On the one hand, problems such as clothing stacking will not occur during the conveying process. On the other hand, the clothes hangers 200 can move individually and can also enter the storage track 107 individually. Therefore, by controlling the connection or disconnection of the track section at the connection of the storage track 107 and the bearing track 63, it is easy to realize the control of the movement path of individual pieces of clothing and sorting and picking, etc., and it is easy to realize automation and reduce labor costs.

[0088] In addition, since the hook 11 is directly installed on the hook seat 12, and at the same time the moving member 15 is also arranged on the hook seat 12, and the connecting member 14 connects the adjacent hook seats 12 to form a continuous arrangement, the installation, movement and arrangement of the hook 11 can be realized simultaneously by these several components, without too many components, and it is easy to realize assembly and maintenance.

[0089] In the embodiment, since the front joint plate 141 cooperates with the front connection end 122A to enable the bird hook seats 12 to rotate left and right, and the rear joint plate 142 cooperates with the rear connection end 122B to enable the bird hook seats 12 to rotate up and down, therefore, the rotation between the bird hook seats 12 has two degrees of freedom and can adapt to different extending directions of the guide rail 62. In addition, since the moving member 15 has a load-bearing member part and also has a guide member part containing guide rollers 155, and the guide rail 63 has a load-bearing flange 621 and also has a guide flange 622 that cooperates with the guide rollers 155, therefore, the moving member 15 can cooperate with the guide rail 62 to move the bird hook seats 12 and the bird hooks 11 forward without skew during the moving process.

[0090] In the embodiment, since the moving member 15 has a central through shaft 152 extending downward, and the central through shaft 152 rotatably connects the front joint plate 141 and the front connection end 122A, therefore, not only can the rotational connection between the bird hook seats 12 be realized, but also the moving member 15 can be exactly located between the two bird hook seats 12, and can drive the bird hook seats 12 to move when moving so as to realize the movement of the bird hooks 11. Since the moving member 15 also has two guide rollers 155 and the guide rail 62 also has a guide flange 622, therefore, the moving member 15 is not prone to offset during the moving process.

[0091] The bird hook conveying unit 61 of this embodiment includes a reset member 13, which can provide a spring force for resetting the bird hook 11; at the same time, the lower side edge of the front part of the bird hook body 111 is an inclined edge, therefore, the bird hook body 111 can be lifted upward by the abutting action of the hook of the clothes hanger 200, and can be reset by the action of the reset member 13 to firmly hook the clothes hanger 200. Thus, the bird hook type conveying unit 61 of this embodiment can pull the clothes hanger 200 to move the clothes hanger 200 along the conveying direction.

[0092] In addition, the length of the bird hook seat 12 in this embodiment is 200 mm, and the length of the bird hook body 111 is 140 mm. Therefore, the length of the bird hook body 111 is shorter than that of the bird hook seat 12, so that the bird hook 11 is completely located inside the bird hook seat 12 in the length direction after installation, and it is not easy for the bird hook 11 to be interfered by other bird hooks 11 during the process of pulling a clothes hanger 200 (especially when the clothes hanger enters the pulling groove 111a). At the same time, therefore, the distance between the pulling grooves 111a on each bird hook 11 is about 200 mm, and this distance is greater than the thickness of various clothes. Therefore, when conveying the clothes hanger 200 with clothes hanging on it, the adjacent clothes will not be squeezed against each other, and can be conveyed in a flat hanging state without wrinkles.

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

[0094] For example, in the embodiment, the connecting member 14 is located at the front connecting end 12A, and there is a rotational connection for left - right rotation between the front end joint portion and the front connecting end 12A, and a rotational connection for up - down rotation between the rear end joint portion and the hook seat 12 in another hook conveying unit 61. However, in the present invention, the connecting member 14 can also be located at the rear connecting end 12B, and a rotational connection is formed between the rear end joint portion and the rear connecting end 12B, and at the same time, a rotational connection is formed between the front end joint portion and the hook seat 12 in another hook conveying unit 61. In addition, the rotational connection relationship between the front end joint portion and the rear end joint portion can also be interchanged, as long as one of them is for up - down rotation and the other is for left - right rotation: for example, there is up - down rotation between the front end joint portion and the front connecting end 12A, and at the same time, there is left - right rotation between the rear end joint portion and the rear connecting end 12B.

[0095] In this embodiment, the length of the hook body 111 is 140 mm, and the length of the seat body 121 of the hook seat 12 is 200 mm. In the present invention, the length of the hook body 111 can also be any length within the range of 80 mm to 300 mm, and the length of the seat body 121 can also be any length within the range of 100 mm to 400 mm, as long as the length of the hook body 111 is shorter than that of the seat body 121.

[0096] In addition, in the embodiment, the driving device 64 can be arranged at any position of the storage receiving track 106, as long as it can cooperate with the hook seat 12, etc. to play a driving role. At the same time, multiple driving devices 64 can also be arranged, distributed at different positions of the storage receiving track 106 to drive simultaneously, so as to enhance the driving force. In addition, a driving motor can also be arranged at the second driving wheel 643 to drive the second driving wheel 643, so that the hook seat 12 can be driven simultaneously from both sides.
