Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and particularly to a multi-directional box-type logistics transfer station and a conveying method thereof. Background Art

[0002] Automated logistics systems are mainly applied in industries such as banks, hospitals, restaurants, and administrative centers. Taking the application in a hospital as an example, boxes containing medicines or medical devices are transported to each nurse station or pharmacy through a conveying channel, and then are taken by doctors and nurses. However, the space of the nurse station and the pharmacy is limited and cannot store a large number of medicines or medical devices. Moreover, the location of incoming goods is too far from the nurse station and the pharmacy, so it is easy that when doctors and nurses need medicines, the medicines or medical devices have not yet reached the nurse station or the pharmacy.

[0003] Therefore, a transfer station is needed to store the boxes of medicines or medical devices. However, because of the traditional transfer station, there is only a single conveying channel and can only achieve one-way conveying. In the actual use process of the transfer station, taking a hospital as an example again, there are surplus or wrong medicines at the nurse station or the pharmacy that cannot be recycled into the transfer station. Summary of the Invention

[0044] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] As Figure 1 shown, the multi-directional box-type logistics transfer station includes a transfer rack 100, a placement rack device 110 evenly distributed on the transfer rack 100, a vertical lifting device 120 arranged in the middle of the transfer rack 100, and a transfer device 130 arranged at the bottom of the transfer rack 100. The box-type article 400 is sent in through the transfer device 130. The vertical lifting device 120 is used to grab the box-type article 400 for movement, and the placement rack device 110 is used to place the box-type article 400. Among them, the transfer device 130 includes a lifting mechanism 200, a telescopic mechanism 300, and a fixed transfer mechanism 131 arranged on the lower sides of the lifting mechanism 200 and the telescopic mechanism 300. Both the lifting mechanism 200 and the telescopic mechanism 300 are movably connected to the transfer rack 100. The fixed transfer mechanism 131 is fixedly screwed to the transfer rack 100. Door devices 500 are provided at one end of the telescopic mechanism 300 and the fixed transfer mechanism 131 away from the lifting mechanism 200, which are used to close the door devices 500 when the transfer station is not in use to prevent dust from entering.

[0046] As Figure 1 shown, the transfer rack 100 is wrapped with an outer shell 140. The outer shell 140 has access openings 141 at both ends of the lifting mechanism 200, the telescopic mechanism 300, and the fixed transfer mechanism 131. The door device 500 is arranged on the transfer rack 100 inside one of the access openings 141.

[0047] As Figure 2As shown, the door device 500 includes a door panel 510 and a synchronous belt mechanism 520 for driving the door panel 510. The door panel 510 is fixed to the synchronous belt of the synchronous belt mechanism 520, and the left and right door panels 510 are respectively fixed to the upper and lower sides of the synchronous belt of the synchronous belt mechanism 520, so that the door panel 510 will move following the synchronous belt mechanism 520 to open and close the loading and unloading port 141. The driving pulley 521 and the driven pulley 522 of the synchronous belt mechanism 520 are fixed to the transfer rack 100 by pedestal bearings 101. A door motor 523 is bolted to the transfer rack 100 at the position of the driving pulley 521. The synchronous belt mechanism 520 is driven by the door motor 523. Door rails 102 are screwed to the transfer rack 100 at the top and bottom positions of the door panel 510. Door sliders 511 are screwed to the top and bottom of the door panel 510. The door sliders 511 are installed on the door rails 102, so that the door sliders 511 can move along the door rails 102.

[0048] As Figure 3 shown, the lifting mechanism 200 includes a conveyor roller structure 600 and a swing arm mechanism 210 arranged on the lower side of the conveyor roller structure 600. Both sides of the swing arm mechanism 210 are installed on the transfer rack 100, and the swing arm mechanism 210 is hinged to the conveyor roller structure 600.

[0049] Specifically, the swing arm mechanism 210 includes a swing arm cylinder 211, a driving swing arm shaft 212, a driven swing arm shaft 213 and a fixed shaft 214. The two ends of the fixed shaft 214 are screwed to the transfer rack 100. The two ends of the driving swing arm shaft 212 and the driven swing arm shaft 213 are both installed on the transfer rack 100 by pedestal bearings 101, and the driving swing arm shaft 212 and the driven swing arm shaft 213 are respectively arranged on both sides of the fixed shaft 214. The two ends of the swing arm cylinder 211 are respectively pin-hinged to the fixed shaft 214 and the driving swing arm shaft 212. The driving swing arm shaft 212 and the driven swing arm shaft 213 are both pin-hinged to the conveyor roller structure 600. Swing arm plates 201 are welded and fixed at the hinge joints of the driving swing arm shaft 212, the driven swing arm shaft 213 and the fixed shaft 214 for hinging.

[0050] When the lifting mechanism 200 rises and the swing arm cylinder 211 extends, it will push the driving swing arm shaft 212 to move counterclockwise, and then push the conveyor roller structure 600 of the lifting mechanism 200 to move upward. At the same time, the driven swing arm shaft 213 is driven to rotate counterclockwise.

[0051] As Figure 3-4As shown in the figure, the telescopic mechanism 300 includes a conveyor roller structure 600 and fixed rods 310 disposed on both sides of the conveyor roller structure 600. The transfer frame 100 is located on both sides of the telescopic mechanism 300 and has a telescopic track 103 fixed by screws. The fixed rods 310 have telescopic sliders 311 fixed by screws. The telescopic sliders 311 are installed on the telescopic tracks 103, enabling the telescopic sliders 311 to move along the telescopic tracks 103. A telescopic motor 320 is bolted to the transfer frame 100 at the lower side position of the conveyor roller structure 600. A rack 330 parallel to the telescopic track 103 is fixed by screws at the lower side of the conveyor roller structure 600. The telescopic motor 320 is connected to the rack 330 by a gear 321, thereby being able to drive the conveyor roller structure 600 of the telescopic mechanism 300 to move.

[0052] As Figure 5 shown in the figure, both the conveyor roller structure 600 and the fixed conveyor mechanism 131 include two fixing plates 610 and roller shafts 620 evenly distributed between the two fixing plates 610. One end of adjacent roller shafts 620 is connected by a conveyor belt 621, and the other end of any one of the roller shafts 620 is connected to a conveyor motor 622.

[0053] Specifically, the conveyor motor 622 of the telescopic mechanism 300 is bolted to the fixed rod 310, the conveyor motor 622 of the lifting mechanism 200 is bolted to the fixing plate 610, and the conveyor motor 622 of the fixed conveyor mechanism 131 is bolted to the transfer frame 100.

[0054] As Figure 6 shown in the figure, the lifting mechanism 200 and the telescopic mechanism 300 are provided with guide plates 104 on both sides at the position directly below the vertical lifting device 120. The guide plates 104 are fixed to the transfer frame 100 by screws. The guide plates 104 are used to adjust the position of the box-shaped article 400 to facilitate the vertical lifting device 120 to grab.

[0055] As Figure 6 shown in the figure, the lifting mechanism 200 and the telescopic mechanism 300 are provided with a photoelectric switch 105 at the position between the door device 500 and the vertical lifting device 120. The photoelectric switch 105 is fixed to the transfer frame 100 by glue. Sensors 106 are provided at the mutually remote ends of the telescopic mechanism 300 and the lifting mechanism 200 for sensing the box-shaped article 400.

[0056] As Figure 7-8 shown in the figure, a limiting mechanism 340 is provided on the telescopic mechanism 300. The limiting mechanism 340 includes two limiters 341 and an induction sheet 342. The induction sheet 342 is fixed to the fixed rod 310 of the telescopic mechanism 300 by screws. The two limiters 341 are fixed to the transfer frame 100 by glue, and the distance between the two limiters 341 is the moving stroke of the telescopic mechanism 300. The induction sheet 342 will pass through the induction position of the corresponding limiter 341.

[0057] As Figure 9 shown, a control system is connected to a placement rack device 110, a vertical lifting device 120, a fixed conveyor mechanism 131, a lifting mechanism 200, a telescopic mechanism 300, a door device 500, a photoelectric switch 105, a sensor 106, and a stopper 341. The control system controls the operation of the placement rack device 110, the vertical lifting device 120, the fixed conveyor mechanism 131, and the door device 500. The control system controls the operation of the lifting mechanism 200 and the telescopic mechanism 300 through the photoelectric switch 105, the sensor 106, and the stopper 341. Specifically, the photoelectric switch 105 and the sensor 106 on the telescopic mechanism 300 are used to sense the position of the box-shaped article 400 on the telescopic mechanism 300, and the photoelectric switch 105 and the sensor 106 on the lifting mechanism 200 are used to sense the position of the box-shaped article 400 on the lifting mechanism 200, and the stopper 341 is used to limit the moving distance of the telescopic mechanism 300. The control system is a commonly used control system for an automated logistics system, enabling the transfer station to be integrated into the entire automated logistics system.

[0058] A conveying method for a multi-directional box-shaped logistics transfer station includes:

[0059] Temporary storage for incoming goods:

[0060] The box-shaped article 400 enters the lifting mechanism 200. The control system controls the lifting mechanism 200 to lift, and the control system controls the operation of the placement rack device 110 and the vertical lifting device 120 to place the box-shaped article 400 on the placement rack device 110.

[0061] Specifically, when the lifting mechanism 200 is not lifted:

[0062] The box-shaped article 400 enters the lifting mechanism 200. The control system senses the box-shaped article 400 through the sensor 106 at the lifting mechanism 200, and then controls the lifting mechanism 200 to convey the box-shaped article 400 to directly below the vertical lifting device 120. When the photoelectric switch 105 senses the box-shaped article 400, the lifting mechanism 200 stops conveying, and then the control system controls the lifting mechanism 200 to rise to a position flush with the telescopic mechanism 300 and stop.

[0063] The control system controls the operation of the placement rack device 110 and the vertical lifting device 120 to place the box-shaped article 400 on the placement rack device 110, and then the lifting mechanism 200 resets.

[0064] When the lifting mechanism 200 has been lifted:

[0065] The steps are the same as above, except that the control system does not need to control the lifting mechanism 200 to rise to a position flush with the telescopic mechanism 300 and stop.

[0066] Furthermore, the transfer station realizes the storage of the box-shaped articles 400 conveyed from two cargo lanes.

[0067] Temporary storage and shipment:

[0068] The control system controls the telescopic mechanism 300 to move towards the lifting mechanism 200 side, and then the control system controls the placement rack device 110 and the vertical lifting device 120 to work, and places the boxed item 400 on the telescopic mechanism 300; the control system controls the telescopic mechanism 300 to move away from the lifting mechanism 200 side, and then the control system controls the telescopic mechanism 200 to convey the boxed item 400 away from the transfer station.

[0069] Specifically, the front lifting mechanism 200 must be in a non-lifted state. The control system controls the telescopic mechanism 300 to move towards the lifting mechanism 200 side until the sensing piece 342 enters the sensing position of the limiter 341 and the telescopic mechanism 300 stops moving. Then the control system controls the placement rack device 110 and the vertical lifting device 120 to work, and places the boxed item 400 on the telescopic mechanism 300; then the control system controls the telescopic mechanism 300 to move away from the lifting mechanism 200 side until the sensing piece 342 enters the sensing position of the limiter 341 and the telescopic mechanism 300 stops moving. Then the control system controls the telescopic mechanism 300 to convey the boxed item 400 away from the transfer station.

[0070] Item return storage:

[0071] The boxed item 400 enters the telescopic mechanism 300. The control system controls the telescopic mechanism 300 to convey the boxed item 400 towards the vertical lifting device 120 side, and then the control system controls the telescopic mechanism 300 to move towards the lifting mechanism 200 side, so that the boxed item 400 is located directly below the vertical lifting mechanism 120; the control system controls the placement rack device 110 and the vertical lifting device 120 to work, and places the boxed item 400 on the placement rack device 110.

[0072] Specifically, the front lifting mechanism 200 must be in a non-lifted state. The boxed item 400 enters the telescopic mechanism 300. The control system senses the boxed item 400 through the sensor 106 at the telescopic mechanism 300, and then controls the telescopic mechanism 300 to convey the boxed item 400 towards the vertical lifting device 120 side until the photoelectric switch 105 senses the boxed item 400 and the telescopic mechanism 300 stops conveying. Then the control system controls the telescopic mechanism 300 to move towards the lifting mechanism 200 side until the sensing piece 342 enters the sensing position of the limiter 341 and the telescopic mechanism 300 stops moving.

[0073] The control system controls the operation of the placement rack device 110 and the vertical lifting device 120 to place the boxed item 400 on the placement rack device 110. Finally, the control system controls the telescopic mechanism 300 to move towards the side away from the lifting mechanism 200 until the sensing piece 342 enters the sensing position of the stopper 341 and the telescopic mechanism 300 stops moving.

[0074] Direct shipping and receiving:

[0075] The control system controls the fixed conveyor mechanism 131 to convey the boxed item 400 to one side, enabling the boxed item to directly pass through the transfer station to achieve shipping and receiving.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
