Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] A two-way transfer device for a logistics box according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0024] See also Figure 1-Figure 15 According to an embodiment of the present application, a two-way transfer device for a logistics material box includes: a trolley main body mechanism 1, a telescopic adjustment mechanism 2, a middle connection mechanism 3, an object movement limiting mechanism 4, a first guide rail portion 5 and a second guide rail portion 6.

[0025] The trolley main body 1 moves to the area where goods need to be loaded and unloaded, and through the cooperation of the telescopic adjustment mechanism 2, the middle connection mechanism 3, the object movement limit mechanism 4, the first guide rail part 5 and the second guide rail part 6, the material box on the platform on one side of the trolley main body 1 can be loaded, or the material box above the trolley main body 1 can be unloaded. Both sides of the trolley main body 1 can load and unload material boxes, which improves the convenience of the trolley in loading and unloading material boxes.

[0026] See also Figure 1-Figure 7 , two sets of telescopic adjustment mechanisms 2 are respectively installed on opposite sides of the cargo space area in the middle of the trolley main body mechanism 1. The telescopic adjustment mechanism 2 includes a back plate 21 and a mobile drive assembly 22. The back plate 21 is fixed on the trolley main body mechanism 1, and the mobile drive assembly 22 is installed on one side of the back plate 21. The side of the back plate 21 is respectively provided with a first notch 23 and a second notch 24. The middle connecting mechanism 3 includes a vertical plate 31, a first connecting belt 34 and a second connecting belt 35. The mobile drive assembly 22 drives the vertical plate 31 above to move. The vertical plate 31 is respectively provided with a first guide wheel 32 and a second guide wheel 33. The first connecting belt 34 slides outside the first guide wheel 32, and one end of the first connecting belt 34 passes through the first notch 23 and is connected to the back plate 21. The second connecting belt 35 slides outside the second guide wheel 33, and one end of the second connecting belt 35 passes through the second notch 24 and is connected to the back plate 21. The object movement limiting mechanism 4 includes a panel 41, a seat shell 42 and a limiting assembly 43. The panel 41 is located in front of the vertical plate 31, and the seat shell 42 is fixed to the top rear side of the panel 41 by bolts. The other end of the first connecting belt 34 and the other end of the second connecting belt 35 are respectively connected to the back of the panel 41, and two sets of limit assemblies 43 are respectively installed at both ends of the seat shell 42. The first guide rail portion 5 connects the back plate 21 and the vertical plate 31, and the second guide rail portion 6 connects the vertical plate 31 and the panel 41.

[0027] When loading the material box on the platform: the main body mechanism 1 of the trolley moves to one side of the platform, and the mobile drive assembly 22 in the telescopic adjustment mechanism 2 drives the upper vertical plate 31 to move. When the vertical plate 31 moves, the second guide wheel 33 and the first guide wheel 32 on it will also move. When the first guide wheel 32 and the second guide wheel 33 move; if it moves toward one end of the first guide wheel 32, the moving first guide wheel 32 drives the panel 41 to move to one side through the first connecting belt 34; if it moves toward one end of the second guide wheel 33, the moving second guide wheel 33 drives the panel 41 to move to the other side through the second connecting belt 35, and the panel 41 that finally moves is longer than the vertical plate 31. The seat shell 42 and the limit assembly 43 also move together with the panel 41. When the panel 41 moves so that the material box is located between the two sets of limit assemblies 43, the limit assembly 43 changes from a vertical position to a horizontal position to limit the material box above the platform. The mobile drive assembly 22 moves in the reverse direction to transfer the material box above the platform to the article-carrying area above the trolley main body mechanism 1. During the process of the trolley moving and transferring the material box, the limiting assembly 43 is always in a lowered parallel state to limit the transferred material box.

[0028] When transferring the material box on the trolley to the top of the platform: the trolley main body 1 moves to one side of the platform, the mobile drive assembly 22 drives the panel 41 and the limit assembly 43 to move, and the moving limit assembly 43 pushes the material box on the top of the trolley to the top of the platform. The transfer equipment trolley can load and unload material boxes on both sides, without the need for manual handling, and the transfer of storage material boxes is more efficient and quick.

[0029] For specific settings, see Figure 1 The main body mechanism 1 of the trolley includes a frame 11 and wheels 12, and the wheels 12 are installed on both sides of the frame 11. The main body mechanism 1 of the trolley also includes a drive control system. The drive control system controls the movement of the wheels 12 to drive the frame 11 to move, that is, the transfer device moves as a whole. Among them, the control system of the trolley is a commonly used wheel and motor drive control system in the field, which is already a prior art and is known to those skilled in the art. The specific structure inside the system will not be repeated here.

[0030] Furthermore, the vehicle main body 1 further comprises anti-collision wheels 13, and four sets of anti-collision wheels 13 are respectively arranged at the four corners of the vehicle frame 11. The anti-collision wheels 13 at the four corners play an anti-collision protection role for the vehicle main body 1.

[0031] For details, please refer to Figure 4The mobile driving assembly 22 includes a rack belt 221, a pulley 222 and a first motor 223. The two pulleys 222 are respectively rotatably arranged on one side of the back plate 21, the rack belt 221 is arranged outside the two pulleys 222, and the first motor 223 is installed on one side of the back plate 21 to drive one pulley 222 to rotate. The middle connecting mechanism 3 also includes a rack plate 36, which is fixed at the bottom of the vertical plate 31 and cooperates with the rack belt 221. The first motor 223 in the mobile driving assembly 22 drives the pulley 222 to rotate, and the rotating pulley 222 will drive the rack belt 221 to move, and the moving rack belt 221 will drive the upper rack plate 36 to move, that is, drive the vertical plate 31 to move. The mobile driving assembly 22 also includes a supporting plate 224, which is located between the two pulleys 222 to support the upper section of the rack belt 221, and the supporting plate 224 is fixed to the back plate 21 by bolts. The supporting plate 224 is used to support the rack plate 36 above, so that the rack plate 36 and the rack belt 221 are more stable when engaged with each other.

[0032] For specific settings, see Figure 8 The limiting assembly 43 includes a fixing seat 431, a second motor 432 and a limiting rod 433. The fixing seat 431 is installed at the end of the seat shell 42. The second motor 432 is arranged on one side of the fixing seat 431 to drive the limiting rod 433 on the other side to rotate. The rotating second motor 432 will drive the limiting rod 433 to adjust and change positions in the vertical direction and the horizontal direction. When the limiting rod 433 is in the vertical position, the notch at the seat shell 42 is used to limit the limiting rod 433 in the vertical position; when the limiting rod 433 is in the horizontal position, the notch at the panel 41 is used to limit the limiting rod 433 to stabilize in the horizontal position.

[0033] The existing commonly used guide rails are prone to serious wear of the internal balls during long-term use, which affects the smoothness of the guide rails. It is also not convenient to add lubricating oil to the inside of the guide rails at a later stage.

[0034] In the above specific implementation, please refer to Figure 9-13, the first guide rail part 5 and the second guide rail part 6 have the same structural specifications. The first guide rail part 5 includes a guide rail shell 51, a guide rail strip 52, an end cover 53, a steel ball 54 and a support member 55. The end cover 53 is fixed to the end of the guide rail shell 51 by bolts, and the guide rail shell 51 and the guide rail strip 52 are slidably arranged. A plurality of steel balls 54 and a support member 55 are arranged in a groove on the inner side of the guide rail shell 51 at intervals, a transverse channel 511 is arranged inside the guide rail shell 51, and a mounting groove 512 is arranged between the transverse channel 511 and the groove. One end of the support member 55 is connected and arranged inside the mounting groove 512, a guide channel 531 connected to the transverse channel 511 is arranged inside the end cover 53, and an oil injection hole 532 connected to the guide channel 531 is arranged at the bottom of the end cover 53. The support member 55 includes a square tube 551 and a positioning column 552. The top of the square tube 551 is installed inside the installation groove 512, and oil inlet holes 553 connected to the horizontal channel 511 are arranged on both sides of the square tube 551, a cavity is arranged inside the positioning column 552, and the cavity inside the positioning column 552 is connected to the square tube 551, ball grooves matching with the steel ball 54 are arranged at both ends of the positioning column 552, and the bottom wall of the ball groove is provided with an oil outlet hole 554 connected to the cavity.

[0035] Lubricating oil is directly applied to the surface of the steel ball 54 inside the guide rail shell 51 from the oil injection hole 532 at the bottom of the end cover 53 regularly. The specific working principle is as follows: lubricating oil is injected from the oil injection hole 532, and the lubricating oil enters the inside of the transverse channel 511 of the guide rail shell 51 through the guide channel 531 inside the end cover 53. The lubricating oil inside the transverse channel 511 then enters the inside of the square tube 551 through the oil inlet hole 553, and the transverse channel 511 is connected to the oil inlet hole 553. The lubricating oil inside the square tube 551 then falls into the cavity inside the positioning column 552, and is finally discharged from the oil outlet hole 554 at one end to the surface of the steel ball 54. When the guide rail moves, the steel ball 54 rolls, and at the same time, the lubricating oil discharged from the oil outlet hole 554 covers the surface of the steel ball 54 and the groove of the guide rail shell 51, which not only has a good anti-friction protection effect on the ball, but also can keep the guide rail shell 51 and the guide rail strip 52 lubricated for a long time. That is, the oil injection structure of the guide rail can realize rapid oil injection of the guide rail and ensure that the guide rail can be lubricated for long-term use.

[0036] The guide rail oiling structure in the above-mentioned two-way transfer device of the logistics material box can realize rapid oiling and lubrication from the inside of the guide rail to the surface of the steel ball 54, but each oiling needs to be added manually. If the lubricating oil can be added by itself, it will make the guide rail lubricating oil addition and use more convenient.

[0037] See also Fig. 9 , Fig.14 and Fig.15The two-way transfer device of the material box also includes an oil storage and oil filling mechanism 7, which includes an oil storage box 71, a box cover 72, a piston plate 73, a pressure plate 74, a second spring 76 and a connecting pipe 78. The box cover 72, the oil storage box 71 and the guide rail housing 51 are fixedly installed by fixing bolts 75. The piston plate 73 is located inside the oil storage box 71, and the piston plate 73 movably penetrates the screw of the fixing bolt 75, and the screw of the fixing bolt 75 above the piston plate 73 is sleeved with an elastic sleeve 77, and the elastic sleeve 77 can be a flexible sleeve made of rubber. One end of the connecting pipe 78 is connected to the oil filling hole 532, and the other end of the connecting pipe 78 is connected to the oil storage box 71, and the second spring 76 is sleeved on the outside of the screw of the fixing bolt 75 located between the piston plate 73 and the bottom wall of the oil storage box 71. The bottom of the pressing plate 74 is fixed to the piston plate 73, and the pressing plate 74 movably penetrates the box cover 72. The bottom of the guide strip 52 is provided with a pressing block 56 located above the pressing plate 74, and the bottom of the pressing block 56 is an arc structure. The top surface of the pressing plate 74 is convex in the middle and gradually tilted downwards towards both ends.

[0038] Fill the oil storage box 71 below the piston plate 73 with lubricating oil in advance. The oil storage box 71 may be additionally provided with an oil filling port and a cover for adding lubricating oil to the oil storage box 71. The second spring 76 outside the fixing bolt 75 is used to elastically support the piston plate 73 above. When the guide rail strip 52 and the guide rail shell 51 move relative to each other, the pressing block 56 at the bottom of the guide rail strip 52 gradually moves and finally presses on the top protrusion of the pressing plate 74, and the pressing plate 74 drives the piston plate 73 to move downward together, and at the same time the second spring 76 is further compressed. The piston plate 73 moving downward compresses the space inside the oil storage box 71, so that part of the lubricating oil inside the oil storage box 71 is squeezed into the guide channel 531 in the end cover 53 through the connecting pipe 78, and then enters the square tube 551 through the transverse channel 511 and the oil inlet hole 553, and finally is discharged from the oil outlet hole 554 at the end of the positioning column 552 and smeared on the surface of the steel ball 54. The lubricating oil stored in the oil storage box 71 can be automatically applied with lubricating oil each time the guide rail strip 52 moves.

[0039] When the guide rail strip 52 is reset, under the elastic force of the second spring 76, the second spring 76 elastically supports the piston plate 73 and the pressing plate 74 to reset, so that the pressing plate 74 can be repeatedly pressed down to load lubricating oil. The elastic sleeve 77 is used to limit the relative distance between the top of the piston plate 73 and the box cover 72. The amount of lubricating oil applied each time can be adjusted according to the relative distance between the vertical position of the pressing block 56 and the pressing plate 74. That is, the outside of the fixing bolt 75 is provided with elastic sleeves 77 of different heights to adjust the relative position between the pressing plate 74 and the pressing block 56 in the vertical direction.

[0040] There are many installation grooves 512 in the guide rail shell 51 of the two-way transfer device of the logistics box. When the lubricating oil enters the horizontal channel 511, it will first flow into the positioning column 552 close to the oil storage box 71, so that the surface of the steel ball 54 close to the oil storage box 71 is pre-coated with lubricating oil, and the steel ball 54 far away from the oil storage box 71 is coated with less lubricating oil, resulting in uneven flow of lubricating oil.

[0041] In the above specific implementation, please refer to Fig.13 The support member 55 further includes a connecting piece 555, a bending piece 556, a positioning rod 557 and a first spring 558. The connecting piece 555 is fixed to the inner wall of the square tube 551 below the oil inlet hole 553, and the connecting piece 555 and the square tube 551 are fixed by welding. One end of the bending piece 556 of the arc structure is connected to the top of the connecting piece 555, and the bending piece 556 and the connecting piece 555 are integrally formed, and the other end of the bending piece 556 is tightly against the other side wall of the square tube 551. The connecting piece 555 and the bending piece 556 block the opening inside the square tube 551. An arc groove 559 is provided on the upper surface of the bending piece 556 near the side wall of the square tube 551. The first spring 558 is provided between the connecting piece 555 and the bending piece 556. The positioning rod 557 is located inside the first spring 558, and one end of the positioning rod 557 is fixed to the connecting piece 555, and a gap is reserved between the other end of the positioning rod 557 and the bending piece 556.

[0042] The lubricating oil inside the oil storage box 71 enters the guide channel 531 in the end cover 53 through the connecting pipe 78, and then enters the square tube 551 close to the oil storage box 71 through the square tube 551 and the oil inlet hole 553. Since the connecting piece 555 and the bending piece 556 inside the square tube 551 play a certain blocking role, when the first square tube 551 close to the end cover 53 is filled with lubricating oil above the bending piece 556, excess lubricating oil will enter the next square tube 551 through the oil inlet hole 553 and the square tube 551, until every square tube 551 in the guide rail shell 51 is filled with lubricating oil. Subsequently, as the pressure block 56 continues to squeeze the pressure plate 74, the lubricating oil inside the transverse channel 511 continues to be pressurized, and finally the pressurized lubricating oil inside the transverse channel 511 simultaneously breaks through the gap between the bending piece 556 and the square tube 551 and enters the cavity inside the positioning column 552, so that the oil outlet holes 554 at the end of each positioning column 552 can simultaneously discharge oil to smear the steel balls 54 on both sides, further improving the uniformity of the lubricating oil smearing on the steel balls 54, that is, further improving the lubrication performance of the guide rail.
