Description

Technical Field

[0001] The present application relates to the technical field of logistics packaging and transportation, and in particular to a blocking mechanism, a shelf, and a goods in-and-out storage system. Background Art

[0002] With the development of science and technology, the automated three-dimensional warehouse in the intelligent logistics system is booming. The automated three-dimensional warehouse uses multi-layer shelves to store goods. The shuttle car is the most important equipment that automatically performs the storage and handling operations of goods in and out of the warehouse. In order to realize the handling operations of the shuttle car between different layers, it is necessary to use the layer-changing elevator to realize the switching of the shuttle car between different layers in the shelf. When the shuttle car changes layers, it drives away from the shelf track and drives into the docking platform on the layer-changing elevator cargo platform. When the cargo platform reaches the designated shelf layer, the shuttle car drives away from the docking platform on the layer-changing elevator cargo platform and drives into the shelf track. In order to prevent the shuttle car from losing control and rushing out of the track and falling when running at the entrance and exit of the shelf track, causing damage to the equipment and even threatening the personal safety of on-site personnel, it is necessary to consider the problem of preventing the shuttle car from losing control and falling.

[0003] There are currently two main solutions in the industry for the problem of shuttle vehicles falling out of control;

[0004] The first solution: an anti-uncontrolled fall device based on the collaborative operation of the shuttle's internal control system requires the installation of mechanisms on both the shuttle and the shelf track system. This solution is only used in a small number of shuttles because of the complexity of the control system, high cost, and easy misoperation, and it cannot completely prevent uncontrolled falls.

[0005] The second solution: install anti-loss-of-control devices on the shelf tracks and the layer-changing elevators, combined with Figure 1 As shown, a structure corresponding to this scheme is given, the blocking device includes a support 1', a blocking structure 2' and a power mechanism 3', the blocking structure 2' and the support 1' are hinged, the power mechanism 3' is arranged on the support 1', and the power mechanism 3' is driven and connected to the blocking structure 2', and the blocking structure 2' can rotate relative to the support 1' under the drive of the power mechanism 3' to switch between the blocking position and the non-blocking position. When the blocking structure 2' is in the blocking position, it can intercept the shuttle car to prevent the shuttle car from running out of control and falling off the track. When the blocking structure 2' is in the non-blocking position, the shuttle car can normally change the layer from the shelf track to the lifting platform or transfer from the platform to the shelf track. Although this scheme is more reliable, such devices in the industry are either more complicated and inconvenient to install, or the installation size and space occupied are large, especially occupying the space above and below the track, resulting in a large minimum distance between each layer of the track of the stereoscopic warehouse and the adjacent upper and lower tracks, thereby reducing the storage capacity of the stereoscopic warehouse at the same height.

[0006] Therefore, there is an urgent need for a blocking mechanism to solve the technical problems existing in the prior art to a certain extent. Utility Model Content

[0061] Embodiment 1

[0062] like Figures 2 to 9 As shown, in this embodiment, a blocking mechanism is provided, which is used for the track level connection between the docking platform and the shelf 5.

[0063] The blocking mechanism includes a housing, a driving member and a blocking member.

[0064] Specifically, the driving member and the blocking member are both arranged in the housing; that is, the housing is surrounded by a receiving space, and the driving member and the blocking member are both arranged in the receiving space; further, the shape of the housing can be Figure 2 The rectangular structure in the embodiment is a rectangular parallelepiped structure, but the present application is not limited to the rectangular parallelepiped shell, and other structures can also be used.

[0065] Specifically, the driving member extends along the first direction 10 , the blocking member extends along the second direction 11 , and the blocking member includes a blocking portion and a reset portion.

[0066] Applying force to the driving member can cause the driving member to overcome the force of the resetting part and move along the first direction 10. When the driving member moves along the first direction 10, it can drive the blocking part to move along the second direction 11 to a non-blocking position, so that the part to be blocked can move along the first direction 10; when the force applied to the driving member is cancelled, the resetting part is reset, and can drive the blocking part to move in a direction opposite to the second direction 11 to a blocking position, and block the part to be blocked from moving along the first direction 10.

[0067] It should be noted that the first direction 10 and the second direction 11 are perpendicular to each other, and the object to be blocked in this embodiment refers to a shuttle.

[0068] In this embodiment, combined with Figure 2 , Figure 3 and Figure 4 As shown, the driving member includes a driving plate 12, a first gear 13 and a gear shaft 14; the blocking member includes a second gear 15, a spring seat 16, a blocking plate 17 that can serve as a blocking portion, and a spring 18 and a guide rod 181 that can serve as a reset portion.

[0069] Specifically, the driving plate 12 extends along the first direction 10, the blocking plate 17 extends along the second direction 11, and the driving plate 12 and the blocking plate 17 are arranged at intervals along the third direction 19, and the first gear 13 and the second gear 15 are sleeved on the gear shaft 14 at intervals along the third direction 19;

[0070] It should be noted that the first direction 10, the second direction 11 and the third direction 19 here just constitute a spatial rectangular coordinate system. Taking this embodiment as an example, the first direction 10 is equivalent to the X-axis direction, the second direction 11 is equivalent to the Y-axis direction, and the third direction 19 is equivalent to the Z-axis direction; further, the driving plate 12 is arranged above the blocking plate 17, and the first gear 13 is arranged above the second gear 15. The driving plate 12 corresponds to the first gear 13, and the blocking plate 17 corresponds to the second gear 15.

[0071] Specifically, the side wall of the driving plate 12 facing the first gear 13 is provided with first gear teeth 20, and the driving plate 12 can be meshed and connected with the first gear 13 through the first gear teeth 20; the side wall of the blocking plate 17 facing the second gear 15 is provided with second gear teeth 21, and the blocking plate 17 can be meshed and connected with the second gear 15 through the second gear teeth 21.

[0072] The bottom of the blocking plate 17 is provided with a receiving cavity 171 arranged along the length direction thereof, the guide rod 181 is arranged in the receiving cavity 171, and both ends of the guide rod 181 are connected to the ends of the receiving cavity 171 in the length direction, the spring seat 16 is connected to the bottom of the housing, and the spring seat 16 has a protrusion 161 that can extend into the interior of the receiving cavity 171, and the protrusion 161 is provided with a hole for inserting the guide rod 181;

[0073] The spring 18 is sleeved on the guide rod 181 , one end of the spring 18 abuts against the side surface of the protruding portion 161 , and the other end of the spring 18 abuts against the end of the accommodating cavity 171 .

[0074] Furthermore, an end plate 45 is provided at the end of the driving plate 12 extending out of the housing, and the end plate 45 is connected to the driving plate 12 via a third connecting member 46. Furthermore, the cross-sectional area of ​​the end plate 45 is larger than the cross-sectional area of ​​the driving plate 12, so that the end plate 45 is advantageously used for contact with external forces. Preferably, the third connecting member 46 is a bolt.

[0075] During actual use, in the static state, that is, when the blocking mechanism is not in use, the drive plate 12 and the blocking plate 17 are both extended out of the shell (the blocking plate 17 is in the blocking position at this time). When the drive plate 12 is driven to retract into the shell along the first direction 10 with a preset force, due to the meshing action of the first gear teeth 20 and the first gear 13, the gear shaft 14 overcomes the elastic force of the spring 18 (at this time, the spring 18 changes from a natural state to a compressed state) and rotates clockwise. The clockwise rotating gear shaft 14 will drive the second gear 15 to rotate clockwise, and due to the meshing action of the second gear 15 and the second gear teeth 21, the blocking plate 17 will be retracted into the shell (the position of the blocking plate 17 when it is retracted into the shell is the non-blocking position). When the preset force applied to the drive plate 12 is released, the spring 18 will reset (at this time, the spring 18 will change from a compressed state to a natural state). The reset of the spring 18 causes the blocking plate 17 to extend out of the housing. Due to the meshing of the second gear teeth 21 and the second gear 15, the second gear 15 and the gear shaft 14 will rotate counterclockwise. The counterclockwise rotating gear shaft 14 will drive the first gear 13 to rotate counterclockwise. Since the first gear 13 is meshed with the first gear teeth 20, the drive plate 12 will also be driven to extend out of the housing.

[0076] In summary, the driving plate 12 and the blocking plate 17 realize the transmission of 90-degree motion under the action of the first gear 13 and the second gear 15, and the transmission ratio is constant, ensuring that the blocking mechanism switches between the blocking position and the non-blocking position, so that the blocking mechanism obtains higher stability and reliability, and the first gear 13 and the second gear 15 are fixed on the same gear shaft 14, ensuring high accuracy of motion transmission, compact structure, and does not occupy the space between the track layers of the shelf.

[0077] In this embodiment, combined Figure 3 As shown, the first gear 13 and the second gear 15 are fixed to the gear shaft 14 through a flat key 23 , and the first gear 13 and the second gear 15 are axially positioned by shaft shoulders on the gear shaft 14 .

[0078] In this embodiment, combined Figure 3 As shown, the blocking member further includes a deep groove ball bearing 24 and a flange bearing 25 .

[0079] Specifically, the deep groove ball bearing 24 is disposed at the end of the gear shaft 14 close to the second gear 15 , and the deep groove ball bearing 24 is spaced apart from the second gear 15 via a thin spacer sleeve 26 .

[0080] Specifically, the flange bearing 25 is disposed at the end of the gear shaft 14 close to the first gear 13 , and the flange of the flange bearing 25 contacts the end surface of the first gear 13 .

[0081] In this embodiment, the shell includes a seat plate 27; specifically, the upper wall surface of the seat plate 27 is provided with a first groove 28 extending along the first direction 10, and the drive plate 12 can be retracted in the first groove 28 or extended from the seat plate 27 along the first direction 10 under the action of a preset force.

[0082] Specifically, a second groove 29 extending along the second direction 11 is defined on the lower wall surface of the seat plate 27 , and the blocking plate 17 can be retracted in the second groove 29 or extended from the seat plate 27 along the second direction 11 under the action of the driving plate 12 .

[0083] Specifically, a through hole 30 is further provided on the seat plate 27 along the third direction 19 , and the through hole 30 is used to accommodate the gear shaft 14 , the first gear 13 and the second gear 15 .

[0084] More specifically, the housing further includes a top plate 31 and a bottom plate; the top plate 31 is buckled on the upper wall surface of the seat plate 27 and fixedly connected by a first connecting member 48, and the top plate 31 can limit the driving plate 12 in the first groove 28 (the limiting here does not mean that the driving plate 12 is completely fixed in the first groove 28; in fact, there is a certain gap between the top plate 31 and the driving plate 12) to prevent the driving plate 12 from falling. The bottom plate is buckled on the lower wall surface of the seat plate 27 and fixedly connected by a second connecting member 47, and the bottom plate can limit the blocking plate 17 in the second groove 29 (the limiting here does not mean that the blocking plate 17 is completely fixed in the second groove 29; in fact, there is a certain gap between the bottom plate and the blocking plate 17) to prevent the blocking plate 17 from falling.

[0085] Furthermore, the bottom plate includes a first pressing plate 43 and a second pressing plate 44 , and the first pressing plate 43 and the second pressing plate 44 are connected to the base via a second connecting member 47 .

[0086] Preferably, the first connecting member 48 and the second connecting member 47 are both bolts.

[0087] In summary, the deep groove ball bearing 24 is separated from the second gear 15 by a thin spacer sleeve 26, and they are all connected in series at the bottom of the gear shaft 14 in a shaft-hole matching manner. The flange bearing 25 is installed on the top of the gear shaft 14 through shaft-hole matching, wherein the flange of the flange bearing 25 contacts the end face of the first gear 13 to form a shaft system assembly together. The entire shaft system assembly is connected to the inner hole on the seat plate 27 through the deep groove ball bearing 24 at the bottom, and is matched with the hole of the top plate 31 through the top flange bearing 25 to form a rotating shaft.

[0088] Embodiment 2

[0089] In this embodiment, a shelf 5 is provided, comprising a track 33 and the above-mentioned blocking mechanism.

[0090] Specifically, refer to Figures 5 to 8Two rails 33 are arranged in parallel to provide a movement path for the blocking member.

[0091] Specifically, the blocking mechanism is disposed at a position of the track 33 corresponding to the input port 35 ; it should be noted that the first direction 10 is the length direction of the track 33 , and the second direction 11 is the width direction of the track 33 .

[0092] In actual use, the shelf 5 is used in an intelligent logistics in-and-out system. The shelf 5 in the intelligent logistics in-and-out system is provided with multi-layer tracks 33 , and the multi-layer tracks 33 are arranged at intervals in the vertical direction.

[0093] When it is necessary to put goods on a certain layer of the shelf 5 or to take goods out of the shelf 5, the shuttle 49 is needed. When the shuttle 49 enters the track 33 of a certain layer of the shelf 5, the blocking plate 17 of the blocking mechanism of the track 33 of that layer is in a non-blocking position under the action of the driving plate 12, that is, the blocking plate 17 is retracted into the shell body, which will not affect the shuttle 49 from entering the track 33 of that layer of the shelf 5; when the shuttle 49 moves on the track 33 of the shelf 5, in order to prevent the shuttle 49 from sliding off the track 33 on the shelf 5, the preset force applied to the driving plate 12 can be canceled at this time, so that the blocking plate 17 is in the blocking position, that is, the blocking plate 17 extends (protrudes) from the shell body toward the inner side of the track 33, thereby blocking the shuttle 49 and preventing the shuttle 49 from sliding off the track 33.

[0094] After the operation of placing or removing the goods on this layer is completed, the shuttle 49 needs to drive out from the shelf 5. At this time, the following operations are performed: the preset force is reapplied to the drive plate 12, so that the drive plate 12 retracts into the shell, and at the same time the blocking plate 17 also retracts until the shell moves to the non-blocking position, that is, the blocking plate 17 no longer blocks the shuttle 49 at this time, and the shuttle 49 can drive out smoothly from the track 33 of the shelf 5.

[0095] In summary, the switching between the non-blocking position and the blocking position of the blocking mechanism can ensure that the shuttle 49 can smoothly enter the shelf 5 or leave the track 33 of the shelf 5, and ensure that when the shuttle 49 is on the track 33 of the shelf 5, the risk of slipping is avoided.

[0096] Embodiment 3

[0097] In this embodiment, a cargo storage system is provided, which includes a layer-changing elevator 4, a cargo platform 39, a docking platform 37, a guide wheel assembly 36 and the shelf 5 in the above-mentioned second embodiment.

[0098] Specifically, the layer-changing elevator 4 is arranged on the opposite side of the input port 35 of the shelf 5, the cargo platform is connected to the layer-changing elevator 4, and the docking platform 37 is connected to the cargo platform 39 through a sliding mechanism 38. The layer-changing elevator 4 is used to transport the parts to be blocked on the docking platform 37 to different inter-layer heights of the shelf 5.

[0099] Specifically, combined Figure 7 and Figure 8 As shown, the guide wheel assembly 36 is connected to the side of the layer-changing elevator 4 facing the shelf 5 through a connecting frame, and corresponds to the blocking member in the first direction 10. A pushing plate 51 is connected to the connecting frame.

[0100] When in use, when the docking platform 37 moves toward the shelf 5, the pushing plate body 51 contacts the end plate 45 on the driving blocking mechanism, pushing the driving plate 12 to move in the first direction, thereby driving the blocking plate 17 (the blocking plate 17 is equivalent to the blocking switch) to overcome the reset spring 18 and retract, and the blocking mechanism is switched from the blocking state to the non-blocking state at this time; when the pushing plate body 51 gradually loses contact with the end plate 45 of the blocking mechanism, under the action of the reset spring 18, the blocking plate 17 is reset, and the blocking mechanism is switched to the blocking state again.

[0101] During actual use, the pushing plate 51 acts as a force-applying member. When the docking platform 37 moves toward the track 33 of the shelf 5, the pushing plate 51 pushes the end plate 45 to move along the first direction 10, so that the blocking member is in a non-blocking position. When the blocking member is in the non-blocking position, the shuttle 49 can move from the docking platform 37 to the track 33 of the shelf 5 or from the track 33 of the shelf 5 to the docking platform 37.

[0102] Combination Figure 5 and Figure 6 As shown, when the shuttle 49 is on the track 33 of the shelf 5, the docking platform 37 moves away from the shelf 5, pushing the plate 51 away from the driving component, and the blocking component is in the blocking position to block the shuttle 49 on the track 33 of the shelf 5 to prevent the shuttle 49 from sliding down.

[0103] In this embodiment, both sides of the docking platform 37 are slidably connected to the cargo platform 39 through a sliding mechanism 38; the sliding mechanism 38 can adopt a structural form of a slide rail and a slider, the electric cylinder 40 is arranged on the cargo platform 39 and connected to the docking platform 37, and the docking platform 37 is driven to slide along the first direction 10 by the telescopic rod of the electric cylinder 40.

[0104] In this embodiment, combined with Fig. 9 As shown, the cargo storage and retrieval system also includes a guide positioning pad 52, a guide positioning C-type plate 41 and a docking wheel set 50.

[0105] The track 33 of the shelf 5 is set as a C-shaped track, and the guide positioning pad 52 is connected to the inner wall of the track 33 by bolts;

[0106] When the blocking mechanism is assembled with the track 33 , the seat plate 27 of the housing in the blocking mechanism is connected to the two side walls of the track 33 by bolts.

[0107] When the push plate 51 moves toward the driving member, the guide wheel assembly 36 can move in the space enclosed by the C-shaped track and the guide positioning pad 52;

[0108] Specifically, the guide positioning C-shaped plate 41 is arranged on the outer side of the track 33 near the entrance, the docking wheel group 50 is connected to the outer side of the docking platform 37 through a bracket, and the guide positioning C-shaped plate 41 corresponds to the position of the docking wheel group 50 in the first direction 10.

[0109] When the docking platform 37 moves toward the track 33 of the shelf 5, the docking wheel set 50 can move in the space surrounded by the guide positioning C-shaped plate 41;

[0110] In addition, the axis of the guide wheel assembly 36 is parallel to the third direction, and the axis of the docking wheel assembly 50 is parallel to the second direction. The guide wheel assembly 36 is used in combination with the space enclosed by the C-shaped track and the guide positioning pad 52, and the docking wheel assembly 50 is used in combination with the space enclosed by the guide positioning C-shaped plate 41, thereby playing a guiding role in both the horizontal and vertical directions, thereby achieving a smooth docking between the docking platform 37 and the track 33 of the shelf 5.

[0111] Specifically, the end of the guide positioning pad 52 is provided with a chamfered angle to guide the guide wheel assembly 36;

[0112] In addition, one side of the guiding and positioning C-shaped plate 41 is configured as a bell mouth, so as to play a guiding role in the up-and-down direction when contacting with the docking wheel set 50 .
