detailed description

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. Please refer to FIGS. 1 to 3, which are preferred embodiments of the present invention.

Please refer to Figures 1 to 3, the present invention provides a logistics lifting system 100, which includes a sending station 1 and a plurality of receiving stations (not shown) arranged in an up-and-down direction. The vertical lifting mechanism 2 that receives the transmission between the receiving stations, and the control unit that controls the operation of the logistics lifting system 100.

In the present invention, a logistics lifting system 100 that transports logistics boxes containing medicines and other materials between various floors in a hospital is used as an example for specific explanation. Generally, the sending site 1 is located on the first floor, and multiple The receiving station is located on the first floor and above; but it should be noted that the technical spirit involved in the following embodiments can be alternatively applied to material transportation in other occasions.

The control unit can follow the control unit in the existing logistics lifting system, such as the programmable logic control unit PLC, which will not be repeated here.

Specifically, the sending station 1 has an output line 11 for outputting the full-contained logistics box at the sending station 1 to the vertical lifting mechanism 2, and the output line 11 has an output direction along the output line 11. A plurality of first roller wires 111 arranged at intervals, a first motor (not shown) for driving the first roller wires 111 to rotate, and the first motor is communicatively connected with the control unit. When the first motor drives the first roller line 111 to rotate, it can drive the logistics box on the output line 11 to move toward the direction where the vertical lifting mechanism 2 is located, so as to be able to move the logistics box to the direction where the vertical lifting mechanism 2 is located. The box is transported into the vertical lifting mechanism 2 and then lifted to the corresponding receiving station by the vertical lifting mechanism 2 for medical personnel to take.

In a specific embodiment, the sending site 1 also has an empty container state in the receiving site recovered by the vertical lifting mechanism 2 to transport and recover the empty container status to the input line 12 in the sending site 1, and at the same time The input line 12 is located on the lower side of the output line 11. It can be understood that the conveying direction of the output line 11 and the input line 12 are opposite.

Specifically, the structure of the input line 12 can follow the structure of the output line 11, that is, the difference between the input line 12 and the output line 11 is only in the conveying direction, and the others are the same. Go into details.

Further, the vertical lifting mechanism 2 includes at least two storage layers 21 arranged at intervals along the vertical direction to increase the storage capacity of the vertical lifting mechanism 2.

The structure of the vertical lifting mechanism 2 can follow the existing car structure, which will not be repeated here. It can be understood that the vertical lifting mechanism 2 has an opening that is open toward the sending station 1 to receive or output a logistics box through the opening.

Specifically, in this embodiment, each storage layer 21 includes a plurality of second roller lines 211 arranged at intervals along the output direction of the output line 11, and a second roller line 211 that drives the second roller line 211 to rotate. Two motors (not shown), the second motor is in communication with the control unit, and the control unit controls the second motor according to specific requirements to drive the second roller line through the second motor 211 rotation.

It is understandable that the second motor can adjust the conveying direction of the logistics box located in the storage layer 21 by changing the rotation direction of the second roller line 211, that is, the logistics box can be fed into the vertical lifting mechanism 2 Or output the logistics box to the vertical lifting mechanism 2.

In a specific embodiment, the number of the storage layer 21 is two layers, namely the upper storage layer 212 and the lower storage layer 213; of course, it is not limited to this.

It can be understood that when the vertical lifting mechanism 2 is located at the sending site 1, and the upper storage layer 212 is opposite to the output line 11, the lower storage layer 213 is opposite to the input line 12, that is, In the prior art, the upper storage layer 212 is generally used to place the full-contained logistics boxes sent from the sending site 1, and the lower storage layer 213 is used to place the empty containers recovered from the receiving site. The logistics box can be recycled to the sending site. As a result, when the vertical lifting mechanism 2 lifts the transporting logistics box from the sending site 1 to the receiving site, only the upper storage layer 212 can be used to place the full-box logistics box. The efficiency is slower.

In the present invention, the control unit can control the vertical lifting mechanism 2 at the sending site 1 to move up and down so that the at least two storage layers 21 can correspond to the output lines 11 respectively, that is, the The vertical lifting mechanism 2 can stay at a position where any one of the at least two storage layers 21 corresponds to the output line 11, so that the output can pass through the at least two storage layers 21 The line 11 is placed with full-packed logistics boxes, which increases the single conveying capacity of the vertical lifting mechanism 2 and improves the conveying efficiency, which meets the existing requirements for the timeliness of material conveying in the hospital.

Specifically, in the embodiment in which the vertical lifting mechanism 2 has an upper storage layer 212 and a lower storage layer 213, the control unit first controls the vertical lifting mechanism 2 to move to and stay on the upper storage layer 212 and At the position corresponding to the output line 11, after the logistics box in the state of full box is filled through the output line 11 in the upper storage layer 212, the vertical lifting mechanism 2 is then controlled to move up a preset distance so that The lower storage layer 213 corresponds to the output line 11, and the lower storage layer 213 can also be filled with a full container through the output line 11, thereby increasing the vertical lifting mechanism 2 The single delivery volume improves the delivery efficiency and meets the existing requirements for the timeliness of material delivery in the hospital.

Further, each storage layer 21 has N storage positions arranged along the output direction of the output line 11, that is, each storage layer 21 can place N full containers at a time for transportation. To the corresponding receiving site.

Wherein, the N is a positive integer, and the N≧2.

In a specific embodiment, each of the storage layers 21 has two storage locations, which are a first storage location 214 and a second storage location 215, respectively. The first storage location 214 is located in the second storage location 215. Inside, that is, the second storage position 215 is closer to the opening than the first storage position 214. When the output line 11 outputs the logistics box, the logistics box continues to move through the second storage position 215 To the first storage location 214, when the logistics box on the first storage location 214 needs to be output, the logistics box needs to pass through the second storage location 215 to output the vertical lifting mechanism 2 again.

Specifically, in this embodiment, each storage location is set as an independent roller line structure, that is, each storage location has a plurality of second roller lines 211 and drives the second roller The second motor that rotates on the line 211, each of the second motors is communicatively connected with the control unit, so as to be able to individually control the start and stop of the roller line structure of each storage position, so as to accurately control the parking position of the logistics box; of course; , Not limited to this.

Further, the output line 11 has N output positions arranged close to the vertical lifting mechanism 2 and arranged along its output direction. The logistics lifting system 100 further includes (N -1) A one-to-one buffer area 3 corresponding to the output location, a transplanting device 4 used to transfer between the buffer area 3 and the corresponding output location, and an identification set at the Nth output location The device 5, the transplanting device 4 and the identification device 5 are all communicatively connected with the control unit.

In a specific embodiment, each of the logistics boxes is affixed with a barcode storing the receiving site information corresponding to the logistics box, and the identification device 5 is a code scanner for identifying the barcode on the logistics box, The control unit controls the output line 11 and the transplanting device 4 according to the receiving site information of the logistics box fed back by the identification device 5 so that the logistics boxes on the output line 11 enter the vertical Lifting mechanism 2 inside.

It is understandable that in the process of the output line 11 conveying the logistics boxes to the vertical lifting mechanism 2, each of the logistics boxes will pass through the Nth output position before continuing to the vertical lifting mechanism. 2 move in the direction where the logistics box is located; when the logistics box is located at the Nth said output position, the identification device 5 recognizes the barcode on the logistics box and feeds back the corresponding receiving site information to the control unit; at the Nth logistics box, it is transported to At the Nth output location, the control unit obtains and compares the receiving site information of the N logistics boxes located at the N output locations, so as to transport the N logistics boxes to the corresponding storage layer 21 in a preset order That is, the N logistics boxes on the storage layer 21 are arranged in a preset order, so that they can be transported to the corresponding receiving station in the preset order, which further improves the transmission efficiency of the logistics improvement system.

In this embodiment, the above-mentioned preset sequence refers to the order of arrival at the receiving station, that is, the logistics boxes that arrive at the corresponding receiving station during the lifting process of the vertical lifting mechanism 2 are first transported to the vertical lifting mechanism 2, therefore, the N logistics boxes located on the storage layer 21 on the first floor are arranged in order of arrival at the receiving station. During the lifting process of the vertical lifting mechanism 2, the logistics boxes at the corresponding receiving station are first reached. The vertical lifting mechanism 2 is delivered first to further improve the transmission efficiency of the logistics lifting system.

Specifically, in this embodiment, each output position is set as an independent roller line structure, that is, each output position has a plurality of first roller lines 111 and drives the first roller line. The first motor that rotates on the line 111, each of the first motors is communicatively connected with the control unit, so as to be able to individually control the start and stop of the roller line structure at each output position, so as to precisely control the transportation of the logistics box; of course, Not limited to this.

In the following, taking the N=2 as an example, the workflow of the logistics improvement system 100 in the present invention will be described in detail:

At this time, it is defined that the output line 11 has a first output position 112 close to the vertical lifting mechanism 2 and a second output position 113 located at an end of the first output position 112 away from the vertical lifting mechanism 2; The buffer area 3 is located at one side of the first output location 112, and the identification device 5 is provided at the second output location 113.

After controlling the vertical lifting mechanism 2 to move so that one layer of the storage layer 21 corresponds to the output line 11, the output line 11 is controlled to start, and the logistics box A is first transported to the second output position 113, and the identification device 5 Recognize the barcode of logistics box A and feed it back to the control unit, and then the output line 11 continues to start, transporting the logistics box A to the first output location 112, and at the same time transporting the logistics box B to the second output location 113, and the identification device 5 identifies the logistics box The barcode of B is fed back to the control unit, and the control unit compares the receiving site information of logistics box A and logistics box B. If the logistics box A arrives at the corresponding receiving site first during the lifting process of the vertical lifting mechanism 2, then, Control the transplanting device 4 to transplant the logistics box A to the buffer area 3, and then control the output line 11 to start, first output the logistics box B to the first storage location 214 in the corresponding storage layer 21, and then control the transplanting device 4 The logistics box A is transplanted to the first output position 112, and the output line 11 is controlled to output the logistics box A to the second storage position 215 in the corresponding storage layer 21, so that the vertical lifting mechanism 2 is lifted upward In the process, the logistics box A that first arrives at the corresponding receiving site can be output to the vertical lifting mechanism 2, and after the logistics box A is transported, continue to be lifted up to the receiving station corresponding to the logistics box B, and then the logistics box B can be output To the corresponding receiving station; if the logistics box B first arrives at the corresponding receiving station during the lifting process of the vertical lifting mechanism 2, the output line 11 is directly controlled to start, and the logistics boxes A and B are delivered to In the corresponding storage layer 21, the logistics box A is located at the first storage position 214, and the logistics box B is located at the second storage position 215. During the upward lifting process of the vertical lifting mechanism 2, it can reach the corresponding receiving site first. The logistics box B outputs the vertical lifting mechanism 2. After the logistics box B is transported, it continues to be lifted up to the receiving station corresponding to the logistics box A, and then the logistics box A can be output to the corresponding receiving station, so that the vertical lifting During the lifting and conveying process of the mechanism 2, there is no need to repeat up and down conveying, which further improves the transmission efficiency of the logistics lifting system 100.

It is understandable that the above workflow only specifically describes the output process of outputting logistics boxes to one of the storage layers 21 through the output line 11, and the output line 11 outputs logistics boxes to the other storage layers 21. The output process is the same as the above-mentioned output process, and will not be repeated here.

In a specific embodiment, the buffer area 3 includes a plurality of third roller lines 31 arranged at intervals, and the arrangement direction of the plurality of third roller lines 31 is the same as the arrangement direction of the first roller lines 111 The same, and the buffer area is set on the side of the corresponding output location, so as not to affect the transportation of the logistics box located on the output line 11; of course, it is not limited to this.

Specifically, the transplanting device 4 includes a transplanting roller line group (not numbered) having a plurality of transplanting roller lines 41, and a lifting motor (not shown) that drives the transplanting roller line group up and down. A rotating motor (not shown) that drives the transplanting roller line 41 to rotate to transfer the logistics box between the buffer area 3 and the corresponding output position.

Specifically, the multiple transplanting roller lines 41 are distributed between the adjacent first roller lines 111 at the corresponding output positions and the adjacent third roller lines in the buffer area 3 corresponding to them. 31, when the logistics box needs to be transferred between the buffer area 3 and the corresponding output position, the lifting motor is controlled to drive the transplanting roller line group to rise to lift up the corresponding logistics box, so that it is located at the output position A plurality of the transplanting roller lines 41 pass through the gap between the adjacent first roller lines 111 and protrude from the upper side of the first roller line 111, and are located in the buffer area 3 The transplanting roller line 41 passes through the gap between the adjacent third roller lines 31 and protrudes from the upper side of the third roller line 31, and then the transplanting roller line 41 is controlled to rotate to achieve The logistics box is transferred between the buffer area 3 and the corresponding output position; after the transfer is completed, the lifting motor is controlled to drive the roller line group down, so that a plurality of the transplanting roller lines 41 located at the output position Passing through the gap between the adjacent first roller lines 111 and located on the lower side of the first roller line 111, a plurality of the transplanting roller lines 41 located in the buffer area 3 pass through the adjacent The gap between the third roller line 31 is located on the lower side of the third roller line 31, so that the transplanting roller line 41 does not interfere with the first roller line 111 to transport the logistics box, and at the same time, The logistics box can be placed in the output location or the buffer area 3.

Further, the present invention also provides a control method for controlling the aforementioned logistics lifting system 100, which includes the following steps:

Therefore, the at least two storage layers 21 can be filled with logistics boxes through the output line 11, which increases the single conveying capacity of the vertical lifting mechanism 2, improves the conveying efficiency, and satisfies the existing requirements. The requirements for the timeliness of the delivery of materials in the hospital.

In a specific embodiment, the vertical lifting mechanism 2 has an upper storage layer 212 and a lower storage layer 213, and the control unit can control the vertical lifting mechanism 2 located at the sending site 1 to move up and down. When 212 corresponds to the output line 11, the full container can be transported to the upper storage layer 212 through the output line 11. When the lower storage layer 213 corresponds to the output line 11, it can pass through the output line 11. The full-box logistics box is transported to the lower storage layer 213, so that both the upper storage layer 212 and the lower storage layer 213 can place the full-box logistics box through the output line 11, which increases the The single conveying volume of the vertical lifting mechanism 2 improves the conveying efficiency and meets the existing requirements for the timeliness of material conveying in the hospital.

In the embodiment in which the vertical lifting mechanism 2 has an upper storage layer 212 and a lower storage layer 213, the above-mentioned steps are specifically as follows:

Control the vertical lifting mechanism 2 to move to and stay at a position corresponding to the upper storage layer 212 and the output line 11, and then control the output line 11 to start transporting the logistics boxes into the upper storage layer 212;

Then control the vertical lifting mechanism 2 to move up a preset distance so that the lower storage layer 213 corresponds to the output line 11, and then control the output line 11 to start transporting the logistics boxes into the lower storage layer 213.

Further, each of the storage layers 21 has N storage positions arranged along the output direction of the output line 11, and the output lines 11 have N storage positions arranged close to the vertical lifting mechanism 2 and arranged along the output direction. N output positions. The logistics lifting system 100 further includes a buffer area 3 corresponding to the (N-1) output positions close to the vertical lifting mechanism 2 in one-to-one correspondence. The transplanting device 4 that transmits between the output positions of, and the identification device 5 arranged at the Nth output position, the transplanting device 4 and the identification device 5 are both communicatively connected with the control unit. Wherein, the N is a positive integer, and the N≥2;

After the storage layer corresponds to the output line, the step of controlling the output line to start to output the logistics box into the storage layer specifically includes the following steps:

It can be understood that the aforementioned N logistics boxes to be transported to the corresponding storage layer refer to N logistics boxes located at N output positions.

By controlling the N logistics boxes to be output to the corresponding storage layer in a preset order, the N logistics boxes are arranged in the N storage positions of the storage layer in a preset order, so that the N logistics boxes can be output to the storage layer in a preset order. The corresponding receiving site.

Specifically, each of the logistics boxes is affixed with a barcode storing the receiving site information corresponding to the logistics box, the identification device 5 is a code scanner for identifying the barcode on the logistics box, and the control unit Control the output line 11 and the transplanting device 4 according to the receiving site information of the logistics box fed back by the identification device 5 so that the logistics boxes on the output line 11 enter the vertical lifting mechanism 2 in a preset order .

In this embodiment, the above-mentioned preset sequence refers to the sequence in which the logistics boxes arrive at the receiving station during the lifting process of the vertical lifting mechanism 2, that is, they will arrive at the corresponding receiving station after the vertical lifting mechanism 2 is lifting. The logistics boxes of the station are first transported to the vertical lifting mechanism 2 so that the N logistics boxes located on the storage layer 21 on the first floor are arranged in order of arrival at the receiving station. During the lifting process of the vertical lifting mechanism 2 In the above, the logistics box that first arrives at the corresponding receiving station is first transported out of the vertical lifting mechanism 2 to further improve the transmission efficiency of the logistics lifting system.

In the following, taking the N=2 as an example, the step of controlling the output line to start after the storage layer corresponds to the output line to output the logistics box to the storage layer is specifically explained:

At this time, it is defined that each of the storage layers 21 has a first storage location 214 and a second storage location 215, wherein the first storage location 214 is located inside the second storage location 215; the output line 11 has a The first output position 112 of the vertical lifting mechanism 2 and the second output position 113 at an end of the first output position 112 away from the vertical lifting mechanism 2; the buffer area 3 is located at the first output position 112 On one side, the identification device 5 is provided at the second output position 113.

At the same time, it is assumed that the logistics boxes to be output from the output line 11 to the corresponding storage layer 21 are logistics box A and logistics box B.

The above steps after the storage layer corresponds to the output line, controlling the output line to start to output the logistics box into the storage layer specifically includes the following steps:

After controlling the vertical lifting mechanism 2 to move so that one layer of the storage layer 21 corresponds to the output line 11, the output line 11 is controlled to start, and the logistics box A is first transported to the second output position 113, and the identification device 5 Recognize the barcode of logistics box A and feed it back to the control unit, and then the output line 11 continues to start, transporting the logistics box A to the first output location 112, and at the same time transporting the logistics box B to the second output location 113, and the identification device 5 identifies the logistics box The bar code of B is fed back to the control unit. The control unit compares the receiving site information of logistics box A and logistics box B, and determines whether the order of logistics box A and logistics box B needs to be exchanged; if so, it controls the transplanting device 4 to transfer the logistics Box A is transplanted to the buffer area 3, and then the output line 11 is controlled to start, and the logistics box B is first output to the first storage location 214 in the corresponding storage layer 21, and then the transplanting device 4 is controlled to transplant the logistics box A to At the first output position 112, the output line 11 is controlled to start to output the logistics box A to the second storage location 215 in the corresponding storage layer 21; if not, the output line 11 is controlled to start, and the logistics boxes A and B are sequentially It is transported to the corresponding storage layer 21 so that the logistics box A is located at the first storage location 214 and the logistics box B is located at the second storage location 215.

It is understandable that if the control unit determines that during the lifting process of the vertical lifting mechanism 2, the logistics box A first arrives at the corresponding receiving station, the order of logistics box A and logistics box B needs to be exchanged; thus, During the upward lifting of the vertical lifting mechanism 2, the logistics box A that first arrives at the corresponding receiving site can be output to the vertical lifting mechanism 2, and after the logistics box A is transported, it continues to be lifted up to the corresponding logistics box B At the receiving station, the logistics box B can be output to the corresponding receiving station; if the control unit determines that during the lifting process of the vertical lifting mechanism 2, the logistics box B arrives at the corresponding receiving station first, then there is no need to exchange The sequence of logistics box A and logistics box B is such that logistics box A is located at the first storage position 214, and logistics box B is located at the second storage position 215. When the vertical lifting mechanism 2 is lifted upwards, it will arrive first. The logistics box B of the corresponding receiving station outputs the vertical lifting mechanism 2, and after the logistics box B is transported, it continues to be lifted up to the receiving station corresponding to the logistics box A, and then the logistics box A can be output to the corresponding receiving station.

Therefore, the vertical lifting mechanism 2 does not need to be repeatedly conveyed up and down during the lifting and conveying process, and the conveying efficiency of the logistics lifting system 100 is further improved.

Correspondingly, the at least two storage layers 21 can be filled with logistics boxes through the output line 11, which increases the single conveyance of the vertical lifting mechanism 2 and improves the conveying efficiency. Meet the existing requirements for the timeliness of the delivery of materials in the hospital.
