Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

The logistics trolley diversion device 100 according to the embodiment of the invention is described below with reference to fig. 1-5.

As shown in fig. 1, 2 and 3, the logistics trolley diversion device 100 according to the embodiment of the invention comprises a base 1, a moving rail 2, a lead screw nut assembly 3 and a bearing seat 4.

Specifically, the screw nut assembly 3 includes a screw 31 and a nut 32, the screw 31 is disposed on the base 1, and the nut 32 is disposed on the moving track 2, so that when the driving device drives the screw 31 to rotate, the nut 32 can reciprocate along the axis of the screw 31, so that the moving track 2 connected to the nut 32 reciprocates along the axis of the screw 31, which is simple in structure and convenient in operation, specifically as shown in fig. 1, the screw 31 extends in the front-back direction, the moving track 2 can move from front to back and can also move from back to front, so that the moving track 2 can be correspondingly matched with different fixed tracks 9 in the front-back direction, so that the logistics trolley can move from the moving track 2 to different fixed tracks 9, and can also move from different fixed tracks 9 to the moving track 2.

As shown in fig. 1, the logistics trolley can move from the fixed rail 9 on the front side to the moving rail 2, and then the moving rail 2 moves from front to back, so that the moving rail 2 corresponds to the fixed rail 9 on the rear side, and at this time, the logistics trolley can move from the moving rail 2 to the fixed rail 9 on the rear side.

However, when the screw nut assembly 3 is used to drive the moving rail 2, the requirement on the coaxiality of the two ends of the screw rod 31 is high, when the coaxiality of the two ends of the screw rod 31 is different, both the moving rail 9 and the screw rod 31 are easily damaged, which is not beneficial to driving, and meanwhile, the screw rod 31 is also easily stuck by the moving rail 2 in the driving process, which causes the bidirectional damage of the moving rail 2 and the screw rod 31.

Based on this, in the present application, in order to reduce the requirement of coaxiality of two ends of the lead screw 31, so that two ends of the lead screw 31 are respectively installed on the base 1 through the bearing seats 4, for example, as shown in fig. 1, the lead screw 31 extends in the front-back direction, the lead screw 31 can be rotated around the axis of the lead screw 31 relative to the bearing seats 4 by arranging the bearing seats 4 between the lead screw 31 and the base 1, and during the rotation of the lead screw 31 around the axis of the lead screw 31, the lead screw 31 can also be rotated around the direction perpendicular to the line where the axis of the lead screw 31 is located relative to the bearing seats 4, specifically, the lead screw 31 can be rotated around the line where the left-right direction is located, or the lead screw 31 can be rotated around the line where the up-down direction is perpendicular to the left-right direction and also perpendicular to the front-back direction, where the up-down direction, the left-right direction, and the front-back direction are only described for convenience, and not as restrictive.

The structure of the bearing housing 4 is described in detail below with reference to fig. 5:

the bearing seat 4 comprises a first inner shaft 41 and a first outer shaft 42, the first outer shaft 42 is sleeved on the first inner shaft 41, the first inner shaft 41 is sleeved on the screw rod 31, the first outer shaft 42 is fixedly connected with the base 1, the screw rod 31 rotates around the axis of the screw rod 31 along a first rotating direction relative to the first inner shaft 41 or the first outer shaft 42, and the first inner shaft 41 rotates around a straight line perpendicular to the axis of the screw rod 31 along a second rotating direction relative to the first outer shaft 42. Here, it should be noted that, in order to better describe the rotation direction of the lead screw 31, the direction of the lead screw 31 around the axis of the lead screw 31 is taken as a first rotation direction, and the direction of the lead screw 31 around the axis perpendicular to the axis is taken as a second rotation direction. Further, in order to better describe the second rotation direction of the lead screw 31 of the present application, in an example, the lead screw 31 uses the bearing seat 4 as a center of a circle, and the lead screw 31 is used as a radius, and can swing in the left-right direction as shown in fig. 1, so that when two ends of the lead screw 31 are not on the same axis, the lead screw 31 can rotate better through the adjustment of the bearing seats 4 at the two ends, thereby reducing the requirement of coaxiality of the two ends of the lead screw 31, and simultaneously reducing the machining precision of the two ends of the lead screw 31, thereby reducing the production difficulty and reducing the production cost.

In addition, it can be understood that both ends of the screw rod 31 can be adjusted to a certain degree, so that both ends of the screw rod 31 have higher degrees of freedom, and the influence caused by machining errors and installation errors can be eliminated, thereby reducing the assembly difficulty and improving the assembly efficiency.

Therefore, according to the logistics trolley turnaround device 100 provided by the embodiment of the invention, the bearing seats 4 are respectively arranged at the two ends of the lead screw 31, so that the two ends of the lead screw 31 have higher degrees of freedom, the requirement on the coaxiality of the two ends of the lead screw 31 can be reduced, the machining precision of the two ends of the lead screw 31 can also be reduced, the production difficulty and the production cost are reduced, the influence caused by machining errors and installation errors can be eliminated, the assembly difficulty is reduced, the assembly efficiency is improved, meanwhile, the lead screw 31 is not easy to be stuck due to the higher degrees of freedom at the two ends of the lead screw 31 in the transmission process, and the transmission effect is good.

In some embodiments of the invention the first inner shaft 41 may be rotatable relative to the first outer shaft 42 about the axis of the screw 31 such that the screw 31 may be rotated about the axis of the screw 31 in a first rotational direction, and in other embodiments of the invention there may be a ball bearing between the first inner shaft 41 and the screw 31, thereby allowing the screw 31 to be rotated relative to the inner shaft about the axis of the screw 31 in the first rotational direction.

In some embodiments of the present invention, in the second rotation direction, the inner wall of the first outer axle 42 is formed with a first arc surface 421 and/or a second arc surface along which the first inner axle 41 rotates along the first arc surface 421 or the first inner axle 41 rotates along the second arc surface. In one example, the inner wall of the first outer axle 42 is formed with a first arc surface 421, and the first inner axle 41 can slide along the first arc surface 421, so that the first inner axle 41 rotates relative to the first outer axle 42 in the second rotation direction; in another example, the inner wall of the first outer axle 42 is formed with a second arc surface along which the first inner axle 41 can slide, thereby rotating the first inner axle 41 relative to the first outer axle 42 in a second direction; in a further example, the inner wall of the first outer axle 42 is formed with a first arc surface 421 and a second arc surface, wherein the first arc surface 421 and the second arc surface are symmetrically disposed on the inner wall of the first outer axle 42, and the symmetry plane is a plane of a middle line in the thickness direction of the first outer axle 42, so that when the first inner axle 41 slides along the first arc surface 421, the first inner axle 41 can rotate relative to the first outer axle 42 in the second rotation direction, and when the first inner axle 41 slides along the second arc surface, the first inner axle 41 can rotate relative to the first outer axle 42 in the opposite direction of the second rotation direction.

In a specific example, the inner wall of the first outer shaft 42 is formed with a first arc surface 421 and a second arc surface, so that when the lead screw 31 is centered at the left bearing seat 4, the lead screw 31 can reciprocally swing in the left-right direction and also reciprocally swing in the up-down direction, thereby enabling the left end of the lead screw 31 to have a higher degree of freedom of rotation, and similarly, the right end of the lead screw 31 can also have a higher degree of freedom of rotation, so as to better reduce the requirement of coaxiality of two ends of the lead screw 31, thereby reducing the production difficulty and the assembly difficulty.

In some embodiments of the present invention, the inner wall of the first outer axle 42 is formed with a first arc surface 421 and a second arc surface, the first arc surface 421 and the second arc surface are symmetrically disposed on the inner wall of the first outer axle 42, and the outer wall of the first inner axle 41 is a plane, that is, as shown in fig. 5, it is possible to make the first inner axle 41 better slide along the first arc surface 421 or the first inner axle 41 better slide along the second arc surface.

Alternatively, the outer wall of the first inner shaft 41 may also be formed as a circular arc surface, so that the first inner shaft 41 can better slide along the first arc surface 421, or the first inner shaft 41 can slide along the second arc surface.

In other examples, the inner wall surface of the first outer axle 42 may have a mating surface with other shapes, and is not limited herein.

In some embodiments of the present invention, as shown in fig. 1 and 2, the logistics trolley diversion device 100 further comprises a floating assembly 5, the floating assembly 5 is disposed between the moving track 2 and the base 1, and the relative position between the moving track 2 and the base 1 can be limited to a certain extent by the arrangement of the floating assembly 5, so that the moving track 2 can better move under the driving action of the lead screw nut assembly 3. Specifically, the floating assembly 5 includes a first frame 51 and a slider 52, the first frame 51 is fixedly connected with the base 1, a sliding slot 511 extending along the axial direction of the lead screw 31 is formed on the first frame 51, the slider 52 is connected with the moving track 2, and the slider 52 is matched with the sliding slot 511. Therefore, when the movable rail 2 moves along the lead screw 31, the movable rail 2 can be well restrained by the engagement between the slider 52 and the slide groove 511.

Further, the slider 52 is movable relative to the sliding slot 511 in a direction perpendicular to the axis of the lead screw 31, where the direction perpendicular to the axis of the lead screw 31 may be a left-right direction or an up-down direction, where in a specific example, the slider 52 is in clearance fit with the sliding slot 511, that is, in the left-right direction, there is a fitting clearance between the slider 52 and the sliding slot 511, and in the up-down direction, there is a fitting clearance between the slider 52 and the sliding slot 511.

In a further example, there is an assembly gap between the slider 52 and the chute 511 in the left-right direction, so that the slider 52 and the chute 511 can move relatively in the left-right direction, and thus, when the screw 31 swings in the left-right direction, the moving rail 2 can swing in the left-right direction, and through the cooperation between the slider 52 and the chute 511, even if the moving rail 2 swings in the left-right direction, the moving rail 2 cannot be jammed in the process of reciprocating in the front-back direction, and the flexibility is good. Further, arc-shaped surfaces which are matched with each other may be formed on the outer wall of the slider 52 and the inner wall of the slide groove 511, respectively, whereby the relative rotation between the slider and the slide groove 511 can be made well.

In some embodiments of the present invention, as shown in fig. 2, the floating assembly 5 further includes a first connecting plate 53, a first mounting block 54 and a second mounting block 55, the first connecting plate 53 is fixedly connected to the moving rail 2, the first mounting block 54 is fixed to the first connecting plate 53, and the second mounting block 55 is connected to the first mounting block 54 to restrain the floating block 52 between the first mounting block 54 and the second mounting block 55.

In the example shown in fig. 1 and 2, the first connecting plate 53 is mounted on the lower end of the moving rail 2, the first connecting plate 53 is assembled by screws, the first mounting block 54 is fixed on the first connecting plate 53 by screws, corresponding bolt holes are formed in the first mounting block 54, the slider 52 and the second mounting block 55 respectively, bolts can sequentially pass through the bolt holes in the first mounting block 54, the slider 52 and the second mounting block 55, and the slider 52 and the second mounting block 55 are fixed on the first mounting block 54.

In another example, the floating block 52 is movably disposed between the first mounting block 54 and the second mounting block 55, for example, as shown in the figure, one end of the floating block 52 is movably disposed in the sliding slot 511, and the other end of the floating block 52 is movably disposed between the first mounting block 54 and the second mounting block 55, thereby further increasing the moving space of the floating block 52 and further reducing the possibility of the moving rail 2 being stuck.

In some embodiments of the present invention, the floating assembly 5 is disposed on at least one side of the moving rail 2 perpendicular to the linear direction of the axis of the lead screw 31. It should be noted here that the direction of the straight line perpendicular to the axis of the lead screw 31 is the left-right direction in fig. 2, and thus, the floating assembly 5 may be disposed below the left end of the moving rail 2, may be disposed below the right end of the moving rail 2, may be disposed below the left end of the moving rail 2 and below the right end of the moving rail 2 at the same time, and may be disposed according to actual circumstances, and is not limited here.

In some embodiments of the present invention, as shown in fig. 1 and 2, the logistics trolley diversion apparatus 100 further includes a slide rail assembly 6, the floating assembly 5 is disposed on one side of the moving rail 2 perpendicular to the linear direction of the axis of the lead screw 31, and the slide rail assembly 6 is disposed on the other side of the moving rail 2 perpendicular to the linear direction of the axis of the lead screw 31. That is, in one example, the slide rail assembly 6 may be disposed below the left end of the moving rail 2, and the floating assembly 5 may be disposed below the right end of the moving rail 2, and in another example, the slide rail assembly 6 may be disposed below the right end of the moving rail 2, and the floating assembly 5 may be disposed below the left end of the moving rail 2. It can be understood that, through setting up slide rail set spare 6, can fix a position moving rail 2's one end betterly to make moving rail 2 can be more stable when along fore-and-aft direction reciprocating motion, be difficult for deviating, can prevent from moving rail 2 and fixed orbit in the in-process that removes and bump, can avoid moving rail 2's damage.

Regarding the slide rail assembly 6, specifically, the slide rail assembly 6 includes a second connecting plate 61 and a second frame 62, the second connecting plate 61 is fixedly connected with the moving rail 2, a sliding block 611 is formed on the second connecting plate 61, a slide rail 621 matched with the sliding block 611 is formed on the second frame 62, and the slide rail 621 extends along the axial direction of the lead screw 31, so that the second connecting plate 61 and the second frame 62 can be well limited by the matching of the slide rail 621 and the sliding block 611.

In the example shown in fig. 1 and fig. 2, in the left-to-right direction of the slide rail 621, the upper surface of the slide rail 621 inclines from top to bottom and then inclines from bottom to top, the shape of the upper surface of the slide rail 621 and the shape of the lower surface of the slide rail 621 are symmetrically arranged, and the upper surface of the slide groove 511 and the lower surface of the slide groove 511 which are correspondingly matched with the upper surface of the slide rail 621 and the lower surface of the slide rail 621 are formed on the slider 611, so that the slide rail 621 and the slide groove 511 can be better matched.

In some embodiments of the present invention, as shown in fig. 1, 3 and 4, the sliding rail assembly 6 further includes a movable block 7, the movable block 7 is disposed between the upper second connecting plate 61 and the nut 32, the movable block 7 includes a nut seat 71, a connecting bearing 72 and a guide rod 73, the nut 32 is fixedly connected to the nut seat 71, the connecting bearing 72 is fixedly connected to the second connecting plate 61, one end of the guide rod 73 is engaged with the nut seat 71, and the other end of the guide rod 73 is rotatably disposed in the connecting bearing 72. Therefore, when the assembly position of the screw 31 in the up-down direction is inclined, the nut 32 engaged with the screw 31 is also inclined in the up-down direction, and at this time, since the guide rod 73 is engaged with the nut seat 71, here, in one example, the nut seat 71 may be fixedly engaged with the guide rod 73, and thus, the moving rail 2 may not be easily stuck when the moving rail 2 reciprocates in the front-back direction by the relative rotation between the guide rod 73 and the connection bearing 72; in another example, the nut seat 71 and the guide rod 73 can rotate relatively, so that the problem that the moving track 2 is not easy to be jammed when the lead screw 31 is inclined can be solved only by the relative rotation between the nut seat 71 and the guide rod 73. In another example, when the two ends of the guide rod 73 can rotate relatively to the nut seat 71 and the connecting bearing 72, the movable block 7 can have a high degree of freedom of rotation, so as to better prevent the moving rail 2 from being locked during the forward and backward movement.

Alternatively, the guide rod 73 and the nut holder 71, and/or the guide rod 73 and the connection bearing 72 are adapted to be relatively slidable in the axial direction of the guide rod 73. That is, in one example, the guide rod 73 and the nut holder 71 may relatively slide in the left-right direction as shown in fig. 1, in another example, the guide rod 73 and the connection bearing 72 may relatively slide in the left-right direction as shown in fig. 1, and in still another example, one end of the guide rod 73 is engaged with the nut holder 71, the guide rod 73 and the nut holder 71 may relatively slide in the left-right direction as shown in fig. 1, the other end of the guide rod 73 may be engaged with the connection bearing 72, and the other end of the guide rod 73 and the connection bearing 72 may relatively slide in the left-right direction as shown in fig. 1.

In a further example, the diameter of the guide rod 73 of the portion where the guide rod 73 is matched with the nut seat 71 is different from the diameter of the guide rod 73 of the portion where the guide rod 73 is matched with the connecting bearing 72, so that the difference in the diameters of the two ends of the guide rod 73 can better determine the rotation direction of the guide rod 73, and simultaneously, the sliding distance between the guide rod 73 and the nut seat 71 and the sliding distance between the guide rod 73 and the connecting bearing 72 can be better limited.

It can be understood that, when the guide rod 73 and the nut seat 71 can slide relatively in the left-right direction, or the guide rod 73 and the connecting bearing 72 can slide relatively in the left-right direction, when the position of the lead screw 31 changes in the left-right direction, the moving rail 2 can not be locked without changing the position in the left-right direction, so as to meet the moving requirement of the moving rail 2.

Optionally, the connecting bearing 72 comprises a second inner shaft 721 and a second outer shaft 722, the second inner shaft 721 and the second outer shaft 722 being adapted to rotate around an axis perpendicular to the second outer shaft 722, wherein the second inner shaft 721 is engaged with the guide rod 73 and the second outer shaft 722 is engaged with the second connecting plate 61. Here, it should be noted that the axial direction of the second outer shaft 722 may refer to the left-right direction shown in the drawing, for example, the second outer shaft 722 and the second inner shaft 721 may rotate around a straight line in the front-back direction, or the second outer shaft 722 and the second inner shaft 721 may rotate around a straight line in the up-down direction, and of course, there may be other rotating directions, which are not described herein too much.

In some embodiments of the present invention, as shown in fig. 1 and 2, the logistics trolley diversion device 100 further includes a drag chain 8, one end of the drag chain 8 is fixedly connected to the base 1, and the other end of the drag chain 8 is fixedly connected to the moving track 2. Therefore, the position of the movable rail 2 can be well limited by arranging the drag chain 8 between the base 1 and the movable rail 2. Specifically, as shown in the figure, the left end of the moving track 2 is positioned through the sliding rail assembly 6, the right end of the moving track 2 is matched through the floating assembly 5, so that the moving track 2 is prevented from being stuck in the moving process, meanwhile, the drag chain 8 is arranged on one side, adjacent to the floating assembly 5, of the moving track 2 to limit the relative position between the base 1 and the moving track 2, and the moving track 2 can better reciprocate along the front-back direction.

The structure and operation of the logistics trolley diversion device 100 according to one embodiment of the invention are described below with reference to the accompanying drawings.

As shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, the logistics trolley turnaround device 100 includes a base 1, a first frame 51 and a second frame 62 are arranged on the base 1 in the left-right direction, the first frame 51 is located on the right side of the base 1, the second frame 62 is located on the left side of the base 1, wherein a plurality of installation slots are arranged on the first frame 51 in the up-down direction, and a sliding rail 621 can be assembled on each installation slot, so that the height of the sliding rail 621 can be adjusted as required, and a plurality of sliding slots 511 are arranged on the second frame 62 in the up-down direction.

Further, the first frame 51 can be matched with the moving rail 2 through the first connecting plate 53, wherein a mounting hole is formed in the first connecting plate 53, a bolt can be matched with the mounting hole to assemble the first mounting block 54 on the first connecting plate 53, and corresponding bolt holes are formed in the first mounting block 54 and the second mounting block 55, so that the floating block 52 can be installed between the first mounting block 54 and the second mounting block 55 through the matching of the bolt holes and the first mounting block 54 and the second mounting block 55, and therefore the floating block 52 can be fixed between the first mounting block 54 and the second mounting block 55, the assembly and disassembly of the floating block 52 can be facilitated, meanwhile, floating blocks 52 with different sizes can be assembled, and the practicability is high.

Further, the slider 52 may be inserted into the sliding slot 511 to be in clearance fit with the sliding slot 511, so that the slider 52 may slide in the up-down direction or the left-right direction with respect to the sliding slot 511, thereby adjusting the relative position between the left end of the moving rail 2 and the first frame 51, and preventing the moving rail 2 from being jammed during the reciprocating movement in the front-rear direction.
