Technical Field

[0001] The invention relates to the field of logistics transportation, and in particular to a layer door mechanism of a vertical sorting machine and a logistics transportation system. Background Art

[0002] As modern hospitals are becoming larger and smarter, and as the transportation of hospital materials (drugs, infusions, consumables, etc.) requires high timeliness, the traditional mode of transporting materials in hospitals is no longer compatible with the needs of hospitals. Based on this, the use of automated logistics transportation systems in hospitals has gradually become popular. In the prior art, automated logistics transportation systems generally include vertical transportation and sorting equipment (sorting machines), horizontal transportation equipment, and transportation carriers. The vertical transportation and sorting equipment is provided with floor doors on each floor, and the horizontal transportation equipment is vertically connected to the vertical transportation and sorting equipment at the door of each floor.

[0003] At present, many sorting equipments are double-layered, with the upper and lower layers transmitting in opposite directions. Generally, the upper layer is used to transmit items, and the lower layer is used to receive items. However, when the transmission volume in one direction is relatively large and the transmission volume in the other direction is relatively small, the transmission efficiency of the logistics conveying system is relatively low in this case, which cannot meet the needs of customers. Summary of the invention

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0025] In the prior art of logistics conveying systems, a double-layer car module is provided in the car of a vertical sorting machine (vertical conveying and sorting equipment), and a double-layer station module is correspondingly provided in the horizontal conveying equipment. The car module has its own forward and reverse transmission function, that is, the two-layer car module can not only transmit items to the station module, but also receive the transmitted items from the station module. The transmission direction of the station module is fixed. Generally, the upper station module is used to transmit items (transmit items to the car module), and the lower station module is used to recover items (receive items transmitted from the car module). Therefore, the upper layer of the corresponding car module is set to receive items, and the lower car module is set to transmit items.

[0026] However, when a station has a large number of items to be transported but relatively few items to be recycled, or when a station has a large number of items to be recycled but relatively few items to be transported, the utilization rate of the two-layer modules is relatively low, and the transportation efficiency of the entire logistics transportation system is low.

[0027] The simplest method is to change the transmission direction of the station module and the car module at the same time. For example, when a station needs to transmit more items but relatively few items to be recycled, both the double-layer station modules are used to transmit items, and the corresponding double-layer car modules are used to receive items. Or when a station needs to recycle a lot of items but relatively few items to be transmitted, both the double-layer station modules are used to recycle items, and the corresponding double-layer car modules are used to transmit items. However, this solution brings two problems: first, the cost of changing the transportation direction of the station module is high; second, the frequent change of the transportation direction of the station module will cause the staff to not know which layer to place the items to be transmitted.

[0028] Therefore, the present invention provides a layer door mechanism of a vertical sorting machine, which greatly improves the transportation efficiency of the entire logistics transportation system by changing the structure of the layer door, has low cost, and does not need to change the transportation direction of the station module. Figure 1 As shown, the landing door mechanism 20 includes a landing door body 21, a door lock device (not shown), a plurality of unlocking devices 22, and a connecting device 24 arranged between at least one unlocking device 22 and the door lock device. Among them, the plurality of unlocking devices 22 are arranged on the landing door body 21, and the plurality of unlocking devices 22 are arranged in sequence in the vertical direction of the landing door body 21, so that when the car 11 of the vertical sorting machine 10 is at different positions of the landing door body 21 in the vertical direction, the door knife 12 arranged on the top of the car 11 can drive different unlocking devices 22 to rotate. When the unlocking device 22 rotates, the unlocking device 22 drives the connecting device 24 to unlock the door lock device.

[0029] It should be noted that the landing door mechanism of the present invention has multiple unlocking devices in the vertical direction. When the unlocking device 22 rotates, the door lock device can be directly unlocked, so that the landing door body 21 can be opened. When the unlocking device 22 is far away from the door lock device, the connecting device 24 can be used to unlock the door lock device when the unlocking device 22 rotates. Therefore, when the car 11 is at different positions of the landing door body 21, the landing door body 21 can be opened, that is, the landing door body 21 has multiple door opening points.

[0030] In a specific embodiment, Figure 1 As shown, the landing door mechanism 20 is provided with three unlocking devices 22, that is, the landing door body 21 has three door opening points. Figure 2As shown, when the car 11 is located at the door opening point A, the door knife 12 on the top of the car 11 can drive the first unlocking device 22 to rotate and open the door locking device, so that the landing door body 21 can be opened when the car 11 is located at the door opening point A. At this time, the station module and the car module are staggered and docked, the station upper module 31 is docked with the car lower module 14, and the station upper module 31 can transfer items to the car lower module 14.

[0031] like Figure 3 As shown, when the car 11 is located at the door opening point B, the door knife 12 on the top of the car 11 can drive the second unlocking device 22 to rotate and open the door locking device, so that the floor door body 21 can be opened when the car 11 is located at the door opening point B. At this time, the station module and the car module are normally docked, that is, the station upper and lower modules 31 and 32 are docked with the car upper and lower modules 13 and 14 respectively, the station upper module 31 transfers the objects to the car upper module 13, and the station lower module 32 receives the objects transferred from the car lower module 14.

[0032] like Figure 4 As shown, when the car 11 is located at the door opening point C, the door knife 12 on the top of the car 11 can drive the third unlocking device 22 to rotate and open the door locking device, so that the landing door body 21 can be opened when the car 11 is located at the door opening point C. At this time, the station module and the car module are staggered and docked, the station lower module 32 is docked with the car upper module 13, and the station lower module 32 can receive the objects transmitted from the car upper module 13.

[0033] Therefore, when a station needs to deliver more items and relatively fewer items to be recovered, a double-layer car module can be set up to receive items, and the car 11 stops at the door opening point A and the door opening point B respectively, and the station upper module 31 delivers the items to the upper and lower modules 13 and 14 of the car. If the car can only receive 2 boxes of items at a time under normal circumstances, the car of the solution of the present invention can receive 4 boxes at a time, doubling the transmission efficiency.

[0034] Similarly, when a station needs to recycle a lot of items but needs to transfer relatively few items, a double-layer car module can be set up to transfer items, the car 11 stops at the door opening point B and the door opening point C respectively, and the upper and lower modules 13 and 14 of the car transfer all the items to the station lower module 32. If the car can only transfer 2 boxes of items at a time under normal circumstances, the car of the solution of the present invention can transfer 4 boxes at a time, doubling the transfer efficiency.

[0035] Therefore, the floor door mechanism of the vertical sorting machine of the present invention installs unlocking devices at different positions in the vertical direction of the floor door body, so that the cars located at different positions of the floor door body can open the floor door body, so that the double-layer car module used to transport items in the car and the double-layer station module of the horizontal conveying equipment can be staggered and docked, thereby greatly improving the transportation efficiency through low-cost changes to meet customer needs.

[0036] In a preferred embodiment, the unlocking device 22 includes a door wheel. When the door knife 12 drives the door wheel to rotate, the door wheel drives the connecting device 24 to unlock the door locking device.

[0037] It should be noted that if the door wheel is directly installed on the floor door body 21, it is necessary to drill holes and install screws on the floor door body 21, which affects the aesthetics of the floor door body 21 on the side of the horizontal transmission equipment 30. Therefore, the floor door mechanism 20 preferably also includes a base plate 23 for installing the door wheel, and the base plate 23 is fixed to the floor door body 21 by welding, which will not affect the aesthetics of the floor door body 21 on the side of the horizontal transmission equipment 30.

[0038] In another preferred embodiment, the connecting device 24 is a serial rod, and when the door knife 12 drives the unlocking device 22 to rotate, the unlocking device 22 drives the serial rod to unlock the door locking device.

[0039] In addition, the vertical distance between adjacent unlocking devices is related to the inter-layer distance of the double-deck car modules arranged in the car, and can be equal to the inter-layer distance between the upper car module 13 and the lower car module 14 (i.e., the inter-layer distance of the double-deck car modules), or the distance difference with the inter-layer distance of the double-deck car modules can be controlled within a certain range.

[0040] It should be noted that, since a plurality of unlocking devices 22 are disposed on the landing door body 21 , the landing door body 21 is relatively high. In order to increase the firmness of the landing door body, a plurality of reinforcing ribs 25 are preferably disposed on the landing door body 21 .

[0041] In addition, in order to meet the fire protection requirements of the landing door body 21 , it is preferred to provide a fireproof coating on the outer surface of the landing door body 21 .

[0042] In a specific embodiment, the floor door mechanism 20 includes a floor door body 21, a door lock device (not shown), three door wheels, and a series rod arranged between two door wheels and the door lock device. Among them, the three door wheels are arranged in sequence in the vertical direction of the floor door body 21, and the distance between adjacent door wheels in the vertical direction is equal to the inter-layer distance of the double-layer car module. When the car is located at the door opening point A, the door knife drives the first door wheel to rotate to unlock the door lock device, thereby opening the floor door body. When the car is located at the door opening point B or the door opening point C, the door knife drives the second or third door wheel to rotate, and the second or third door wheel drives the series rod to unlock the door lock device, thereby opening the floor door body. At the same time, a plurality of reinforcing ribs are arranged on the floor door body, the outer surface of the floor door body is provided with a fireproof coating, and a bottom plate is welded on the floor door body for installing door wheels.

[0043] like Figure 5 As shown, the present invention further provides a logistics conveying system, which includes a vertical sorting machine 10 and a horizontal conveying device 30. The vertical sorting machine is provided with a floor door mechanism described in any of the above schemes on each floor.

[0044] In a specific embodiment, the vertical sorting machine 10 is provided with a car 11 that moves in the vertical direction, and a door knife 12 is provided on the top of the car 11, and the door knife 12 can drive the unlocking device 22 of the floor door mechanism 20 to open the door locking device of the floor door mechanism 20. A double-layer car module for conveying articles is provided in the car, and the conveyor belt of the double-layer car module has forward and reverse functions. The horizontal conveying equipment 30 is provided with a double-layer station module, the upper module 31 of the station is used to convey articles to the car module, and the lower module 32 of the station is used to receive articles conveyed from the car module.

[0045] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0046] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
