[0091] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings. Example embodiments, however, can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and thus description of the same will be simplified or omitted.

[0092] As shown in Figure 1 and Figure 2 , the multi-pass warehouse system 1 of the embodiment of the present application comprises a first base 11, a second base 12, and a track connection device 13, the track connection device 13 is arranged between the first base 11 and the second base 12, and is used to bridge the first base 11 and the second base 12, so that a walking device can move back and forth between the first base 11 and the second base 12 through the track connection device 13.

[0093] In the embodiment of the present application, the first base 11 is a shelf of the multi-pass warehouse system 1, and the second base 12 is a hoist of the multi-pass warehouse system 1. Of course, in other embodiments, when the track connection device 13 is applied to other scenarios, the first base 11 and the second base 12 can also be other components, which will not be described here.

[0094] It can be understood that the terms "comprising" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally also include steps or units not listed, or can optionally also include other steps or components inherent to these processes, methods, products or devices.

[0095] As an example, the walking device comprises a shuttle. Of course, in other embodiments, the walking device can also be other devices capable of moving along the track, which will not be described here.

[0096] As shown in Figures 3 to 5 , the track connection device 13 comprises a first track 200, a second track 400, a first stop component 600, and a second stop component 800. The first track 200 is connected to the first base 11, and the second track 400 is connected to the second base 12.

[0097] The positions between the second track 400 and the first track 200 include a separated position and a docked position. In the separated position, the second track 400 is separated from the first track 200. In the docked position, the second track 400 is docked with the first track 200 and forms a continuous track for the walking device to walk on.

[0098] In the embodiment of the present application, the first track 200 is a fixed track and the second track 400 is a movable track. Further, the first track 200 is fixedly connected to the first base 11 and the second track 400 is movably connected to the second base 12.

[0099] Of course, in other embodiments, the first track 200 and the second track 400 can also be arranged in the following manners: the first track 200 is movably connected to the first base 11 and the second track 400 is fixedly connected to the second base 12; or the first track 200 is movably connected to the first base 11 and the second track 400 is movably connected to the second base 12.

[0100] The first stop component 600 is connected to the first track 200 for stopping the walking device from walking along the first track 200 towards the second track 400 when the second track 400 and the first track 200 are in the separated position. The second stop component 800 is connected to the second track 400 for stopping the walking device from walking along the second track 400 towards the first track 200 when the second track 400 and the first track 200 are in the separated position.

[0101] It can be understood that the track connection device 13 of the embodiment of the present application includes the first track 200, the second track 400, the first stop component 600 and the second stop component 800. The first stop component 600 is connected to the first track 200 for stopping the walking device from walking along the first track 200 towards the second track 400 when the second track 400 and the first track 200 are in the separated position. The second stop component 800 is connected to the second track 400 for stopping the walking device from walking along the second track 400 towards the first track 200 when the second track 400 and the first track 200 are in the separated position. In this way, the first stop component 600 and the second stop component 800 respectively function as stop components for the walking device when the first track 200 and the second track 400 are in the separated position, preventing the walking device from falling from the gap between the first track 200 and the second track 400 and causing safety problems.

[0102] As Figure 5 and Figure 6As shown, the first stop assembly 600 includes a first mount 610 and a first stop 620. The first mount 610 is mounted to the first rail 200, and the first stop 620 is movably connected to the first mount 610. The position of the first stop 620 relative to the first rail 200 includes a first release position and a first stop position. In the first stop position, at least a portion of the first stop 620 extends beyond the first rail 200 toward the first load bearing surface 210 of the walking device. In the first release position, the first stop 620 does not extend beyond the first load bearing surface 210.

[0103] The second stop assembly 800 includes a second mount 810 and a second stop 820. The second mount 810 is mounted to the second rail 400, and the second stop 820 is movably connected to the second mount 810. The position of the second stop 820 relative to the second rail 400 includes a second release position and a second stop position. In the second stop position, at least a portion of the second stop 820 extends beyond the second rail 400 toward the second load bearing surface 410 of the walking device. In the second release position, the second stop 820 does not extend beyond the second load bearing surface 410.

[0104] In the embodiment, the first stop 620 is movable relative to the first mount 610 between the first stop position and the first release position, and the second stop 820 is movable relative to the second mount 810 between the second stop position and the second release position. When the second rail 400 is in the separated position relative to the first rail 200, the first stop 620 is in the first stop position to prevent movement of the walking device along the first rail 200 toward the second rail 400, and the second stop 820 is in the second stop position to prevent movement of the walking device along the second rail 400 toward the first rail 200. When the second rail 400 is in the docked position relative to the first rail 200, the first stop 620 is in the first release position to allow movement of the walking device along the first rail 200 toward the second rail 400, and the second stop 820 is in the second release position to allow movement of the walking device along the second rail 400 toward the first rail 200.

[0105] In the embodiment, the first stop 620 is movable relative to the first mount 610 between the first stop position and the first release position, and the second stop 820 is movable relative to the second mount 810 between the second stop position and the second release position. When the second rail 400 is in the separated position relative to the first rail 200, the first stop 620 is in the first stop position to prevent movement of the walking device along the first rail 200 toward the second rail 400, and the second stop 820 is in the second stop position to prevent movement of the walking device along the second rail 400 toward the first rail 200. When the second rail 400 is in the docked position relative to the first rail 200, the first stop 620 is in the first release position to allow movement of the walking device along the first rail 200 toward the second rail 400, and the second stop 820 is in the second release position to allow movement of the walking device along the second rail 400 toward the first rail 200.

[0106] Thus, in the embodiment of the present application, by moving the first stopper 620 and the second stopper 820, the first track 200 and the second track 400 can be limited to the walking device before the first track 200 and the second track 400 are connected, and the first track 200 and the second track 400 can be released from the limitation to the walking device after the first track 200 and the second track 400 are connected, so that the walking device can walk on the continuous track formed by the first track 200 and the second track 400.

[0107] As shown in Figure 5 , the first mounting seat 610 is mounted on the bottom surface of the first track 200, and the second mounting seat 810 is mounted on the bottom surface of the second track 400. Of course, in other embodiments, the first mounting seat 610 can also be mounted on the side surface of the first track 200, and the second mounting seat 810 can also be mounted on the side surface of the second track 400. In addition, the first mounting seat 610 and the second mounting seat 810 are not limited to be mounted on the same side of the track, for example, the first mounting seat 610 is mounted on the bottom surface of the first track 200, and the second mounting seat 810 is mounted on the side surface of the second track 400, as long as the function of stopping the walking device can be achieved.

[0108] As shown in Figure 5 , the first stopper 620 is movably connected to the first mounting seat 610 in a direction perpendicular to the extension direction of the first track 200. The second stopper 820 is movably connected to the second mounting seat 810 in a direction perpendicular to the extension direction of the second track 400.

[0109] When the first stopper 620 is in the first stop position, at least part of the first stopper 620 protrudes from the first mounting seat 610 and protrudes from the first bearing surface 210 of the first track 200. When the first stopper 620 is in the first release position, the first stopper 620 is retracted into the first mounting seat 610, and the first stopper 620 does not protrude from the first bearing surface 210.

[0110] When the second stopper 820 is in the second stop position, at least part of the second stopper 820 protrudes from the second mounting seat 810 and protrudes from the second bearing surface 410 of the second track 400. When the second stopper 820 is in the second release position, the second stopper 820 is retracted into the second mounting seat 810, and the second stopper 820 does not protrude from the second bearing surface 410.

[0111] As shown in Figure 5 and Figure 6As shown, the first rail 200 is provided with a first through hole 220 penetrating the first bearing surface 210, the first mounting seat 610 is provided with a third through hole 611 corresponding to the first through hole 220, and the first stopper 620 is movably penetrated in the first through hole 220 and the third through hole 611. When the first stopper 620 is in the first stop position, at least part of the first stopper 620 extends out of the first bearing surface 210 through the third through hole 611 and the first through hole 220.

[0112] The second rail 400 is provided with a second through hole 420 penetrating the second bearing surface 410, the second mounting seat 810 is provided with a fourth through hole 811 corresponding to the second through hole 420, and the second stopper 820 is movably penetrated in the second through hole 420 and the fourth through hole 811. When the second stopper 820 is in the second stop position, at least part of the second stopper 820 extends out of the second bearing surface 410 through the fourth through hole 811 and the second through hole 420.

[0113] It can be understood that the moving track of the first stopper 620 can be rotation relative to the first mounting seat 610 in addition to moving along the direction perpendicular to the extending direction of the first rail 200. Similarly, the moving track of the second stopper 820 can be rotation relative to the second mounting seat 810 in addition to moving along the direction perpendicular to the extending direction of the second rail 400.

[0114] As shown in Figure 6 and Figure 7 The first stopper assembly 600 further comprises a first elastic member 630 and a pressing member 640. The first elastic member 630 is used to provide an elastic force to the first stopper 620 to move to the first stop position. The pressing member 640 is mounted on the second mounting seat 810 and is used to press the first stopper 620 when the second rail 400 moves to the first rail 200, so that the first stopper 620 moves from the first stop position to the first release position against the elastic force of the first elastic member 630.

[0115] The second stopper assembly 800 further comprises a second elastic member 830 and a guide member 840. The second elastic member 830 is used to provide an elastic force to the second stopper 820 to move to the second release position. The guide member 840 is fixedly connected to the second base 12 and is used to abut with the second stopper 820 to guide the second stopper 820 to move from the second stop position to the second release position when the second rail 400 moves to the first rail 200.

[0116] In this embodiment, the first stop member 620 is driven to move from the first stop position to the first release position by the pressure exerted by the pressing member 640 on the first stop member 620, and the first stop member 620 is driven to move from the first release position to the first stop position by the elastic force exerted by the first elastic member 630 on the first stop member 620. The pressing member 640 is mounted on the second mounting base 810, which is connected to the second track 400. Therefore, when the second track 400 moves towards the first track 200, the pressing member 640 can press the first stop member 620 to move towards the first release position. When the second track 400 moves away from the first track 200, the pressure exerted by the first stop member 620 disappears, and under the action of the first elastic member 630, the first stop member 620 returns to the first stop position.

[0117] For the second stop 820, the elastic force exerted by the second elastic member 830 on the second stop 820 drives the second stop 820 to move from the second stop position to the second release position, and the abutment of the guide member 840 drives the second stop 820 to move from the second release position to the second stop position. The guide member 840 is fixedly connected to the second base 12, and the second track 400 is movable relative to the second base 12, so the second track 400 can move relative to the guide member 840. When the second track 400 moves from the separation position to the first track 200, the second mounting base 810 drives the second stop 820 and the second elastic member 830 to move together, and move relative to the guide member 840. Thus, under the action of the second elastic member 830, the second stop 820 moves along the guide member 840 from the second stop position to the second release position. When the second track 400 moves away from the docking position away from the first track 200, the second mounting base 810 also drives the second stop 820 and the second elastic member 830 to move, and moves relative to the guide member 840. In this way, the guide member 840 abuts against the second stop 820, overcomes the elastic force of the second elastic member 830, and moves from the second release position to the second stop position.

[0118] In one embodiment, the first elastic element 630 and the second elastic element 830 may be springs, but are not limited thereto.

[0119] like Figure 6 and Figure 7As shown, the abutting member 640 is provided with a first inclined surface 641 which is inclined upwardly towards the direction close to the first track 200, and the first inclined surface 641 is used to abut against the first stop member 620 so that the abutting force of the abutting member 640 on the first stop member 620 generates an abutting component force along the moving direction of the first stop member 620 relative to the first mounting base 610, so as to move the first stop member 620 from the first stop position to the first release position. When the second track 400 moves away from the first track 200, the first stop member 620 is moved from the first release position to the first stop position along the first inclined surface 641 of the abutting member 640 under the action of the first elastic member 630.

[0120] The guide member 840 is provided with a second inclined surface 841 which is inclined downwardly towards the direction close to the first track 200, and the second inclined surface 841 is used to abut against the second stop member 820 so that when the second track 400 moves towards the first track 200, the second mounting base 810 and the guide member 840 generate relative movement, and the elastic force of the second elastic member 830 drives the second stop member 820 to move along the second inclined surface 841 so as to move the second stop member 820 from the second stop position to the second release position. When the second track 400 moves away from the first track 200, the second stop member 820 is abutted by the second inclined surface 841 and is moved from the second release position to the second stop position against the elastic force of the second elastic member 830.

[0121] As shown in Figure 7 , the abutting member 640 further comprises a first flat surface 642 which is connected with the first inclined surface 641, and the first flat surface 642 is used to abut against the first stop member 620 when the first track 200 and the second track 400 are located at the docking position, so as to keep the first stop member 620 at the first release position.

[0122] As shown in Figure 8 , the guide member 840 further comprises a second flat surface 842 which is connected with the second inclined surface 841, and the second flat surface 842 is used to abut against the second stop member 820 when the first track 200 and the second track 400 are located at the separation position, so as to keep the second stop member 820 at the second stop position.

[0123] Referring back to Figure 6 , the first mounting base 610 is provided with a first guide groove 612 which extends along the moving direction of the first stop member 620 relative to the first mounting base 610. The second mounting base 810 is provided with a second guide groove 812 which extends along the moving direction of the second stop member 820 relative to the second mounting base 810.

[0124] The first stopper 620 comprises a first stopper rod 621, a first connecting rod 622 and a first stopper ring 623. The first connecting rod 622 is transversely arranged in the first guide slot 612 and is movable along the first guide slot 612. The first connecting rod 622 is used to abut against the pressing member 640. When the first stopper rod 621 is in the first release position, the first connecting rod 622 abuts against the first flat surface 642. When the first stopper rod 621 is switched between the first release position and the first stop position, the first connecting rod 622 abuts against the first inclined surface 641.

[0125] The first stopper rod 621 is connected to the first connecting rod 622. The first stopper rod 621 is used to stop the walking device from walking along the first track 200 towards the second track 400 when the second track 400 and the first track 200 are in the separated position. When the first stopper 620 is in the first stop position, part of the first stopper rod 621 extends out of the first bearing surface 210 of the first track 200 through the third through hole 611 and the first through hole 220. When the first stopper 620 is in the first release position, the first stopper rod 621 is retracted into the first mounting seat 610.

[0126] The first stopper ring 623 is sleeved on the outer periphery of the first stopper rod 621. The two ends of the first elastic member 630 abut against the first mounting seat 610 and the first stopper ring 623 respectively. It can be understood that in order to make the first elastic member 630 have an elastic force for moving the first stopper 620 to the first stop position, the upper end of the first elastic member 630 abuts against the first stopper ring 623, and the lower end of the second elastic member 830 abuts against the lower part of the first mounting seat 610.

[0127] Continuing to refer to Figure 6 The second stopper 820 comprises a second stopper rod 821, a second connecting rod 822 and a second stopper ring 823. The second connecting rod 822 is transversely arranged in the second guide slot 812 and is movable along the second guide slot 812. The second connecting rod 822 is used to abut against the guide member 840. When the second stopper rod 821 is in the second stop position, the second connecting rod 822 abuts against the second flat surface 842. When the second stopper rod 821 is switched between the second release position and the second stop position, the second connecting rod 822 abuts against the second inclined surface 841.

[0128] The second stop lever 821 is connected to the second connecting rod 822, and is used to stop the walking device from walking along the second track 400 towards the first track 200 when the second track 400 and the first track 200 are in the separated position. When the second stopper 820 is in the second stop position, part of the second stop lever 821 extends out of the second bearing surface 410 of the second track 400 through the fourth through hole 811 and the second through hole 420. When the second stopper 820 is in the second release position, the second stop lever 821 is retracted into the second mounting seat 810.

[0129] The second stop ring 823 is sleeved on the outer periphery of the second stop lever 821. The two ends of the second elastic member 830 abut against the second mounting seat 810 and the second stop ring 823 respectively. It can be understood that, in order to enable the second elastic member 830 to provide an elastic force for moving the second stopper 820 to the second release position, the upper end of the second elastic member 830 abuts against the upper part of the second mounting seat 810, and the lower end of the second elastic member 830 abuts against the second stop ring 823.

[0130] As shown in Figs. Figure 7 and Figure 9 The track connection device 13 further comprises a guide assembly 900 arranged on the first track 200 and / or the second track 400, and used to guide the second track 400 and the first track 200 to switch between the connected position and the separated position. By arranging the guide assembly 900, the first track 200 and the second track 400 can be more easily connected, the first bearing surface 210 of the first track 200 and the second bearing surface 410 of the second track 400 can be ensured to be flush, and the walking of the walking device on the track can be ensured.

[0131] It can be understood that the guide assembly 900 can be arranged on the first track 200, or can be arranged on the second track 400, or can be arranged on both the first track 200 and the second track 400.

[0132] As an example, the guide assembly 900 comprises a guide member 910 and a pair of guide strips 920. The guide member 910 is arranged on one of the first stop assembly 600 and the second stop assembly 800. The pair of guide strips 920 is arranged on the other of the first stop assembly 600 and the second stop assembly 800. The pair of guide strips 920 forms a guide groove 922 therebetween, and the guide groove 922 extends along the moving direction of the second track 400 and the first track 200 relative to each other. The guide member 910 is used to be inserted into the guide groove 922.

[0133] In the embodiment of the present application, the guide member 910 is arranged on the outer side of the second mounting seat 810, and the pair of guide strips 920 is arranged on the outer side of the first mounting seat 610.

[0134] Each guide strip 920 is provided with a guide inclined surface 921 at one end close to the guide member 910, and the two guide inclined surfaces 921 extend in a direction away from each other and towards the guide member 910. In other words, the two guide inclined surfaces 921 of the two guide strips 920 have an outwardly expanding structure. When the second track 400 is connected to the first track 200, the two guide inclined surfaces 921 guide the guide member 910, so that the guide member 910 is more easily inserted into the guide groove 922, thereby achieving the guiding effect.

[0135] The guide member 910 includes a guide rod 911 and a guide wheel 912, and the guide rod 911 is arranged on one of the first stop component 600 and the second stop component 800. The guide wheel 912 is rotatably connected to the guide rod 911. In the embodiment, the guide rod 911 is arranged on the outer side of the second mounting seat 810. When the guide member 910 is inserted into or pulled out of the guide groove 922, the guide wheel 912 is in rolling contact with the two guide strips 920, thereby reducing the friction between the guide member 910 and the guide strips 920 and reducing the wear of the guide member 910 and the guide strips 920.

[0136] In other embodiments, the first stop component 600 and the second stop component 800 can have the same structure, which can be the structure of the first stop component 600 in the above embodiment or the structure of the second stop component 800 in the above embodiment.

[0137] In other embodiments, only one of the first stop component 600 and the second stop component 800 can exist, and not both. For example, when the track is a one-way track, i.e., the walking device always transitions from the first track to the second track in one direction, only the first stop component is needed.

[0138] It can be understood that when the track connection device of the embodiment includes only one stop component, the stop component can be arranged on the first track 200 or the second track 400. Meanwhile, the stop component can be the first stop component 600 of the above embodiment or the second stop component 800 of the above embodiment.

[0139] When the stop component is the first stop component 600 of the above embodiment, the pressing member 640 of the first stop component 600 can be fixedly installed on the second track 400. When the stop component is the second stop component 800 of the above embodiment, the guide member 840 of the second stop component 800 can be fixedly installed on the second base 12.
