Description

Technical Field

[0001] The invention belongs to the technical field of boxed medicine sorting, and in particular relates to a system for automatically sorting multiple varieties of boxed medicines in a warehouse at the same time. Background Art

[0002] In the past, the research and development of drug sorting technology has focused on automatic drug vending machines in pharmacies and automated systems in hospital pharmacies. The automatic drug vending machines use a coordinate manual sorting mode, which was originally designed to meet the instant drug purchase needs of individual consumers in retail drug stores. However, this mode has significant limitations. Due to the large scale and complex layout of drug storage in warehouses, its small operating space and relatively simple sorting logic cannot adapt to the sorting tasks of massive drugs in warehouses.

[0003] Hospital unmanned automatic pharmacies are designed to cope with the situation where there are relatively few varieties of drugs in hospitals, limited customer demand, and high requirements for timely drug collection. Such pharmacies usually reserve common drugs, lack flexibility in drug reserve types, storage quantities, and response to large-scale order fluctuations, and cannot be transplanted to the complex environment of large drug warehouses.

[0004] In the past, the operation mode of large-scale pharmaceutical warehouses was relatively extensive, and the shipments were mainly whole pieces, with less split pieces, and the problem of sorting efficiency was not prominent. However, in recent years, with the change of market consumption habits, especially the booming of modern pharmaceutical e-commerce, the consumer end has shown a trend of small-batch and diversified purchases, which has directly led to a sharp increase in the number of split-piece orders in large warehouses, while the proportion of whole piece orders has dropped significantly. At present, even though some warehouses have adopted a relatively advanced order drug location and quantity light prompt system, which has reduced the time for manual search for drugs to a certain extent, it still relies on manual sorting in essence. After sorting, the order is placed on the conveyor belt and sent to the review table. Although this method has improved efficiency to a certain extent, it has not fundamentally solved the bottleneck of sorting efficiency. Problems such as time-consuming walking movement and hand-eye coordination errors that are difficult to avoid in manual operations still exist. Problems such as quantity counting errors, batch number confusion, mismatch of origin information, and violation of the first-in-first-out principle resulting in the last-in-first-out of goods frequently occur, which brings great trouble to drug quality control and logistics operations. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention closely coordinates and highly automates each link from order reception, drug storage, sorting and grabbing to review and packaging, and strives to meet the growing complex sorting needs of large-scale pharmaceutical warehouses with the least manpower input, the highest accuracy and the fastest speed.

[0006] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: the present invention provides a system for automatically sorting multiple varieties of boxed medicines in a warehouse at the same time, which is composed of an order system, an order drive system, multiple groups of shelves, multi-layer medicine troughs, sorting hands, guide deceleration cloth bags, summary transmission belts and composite packaging tables, wherein the multi-layer medicine trough includes an export rotating pallet, which is arranged at the front end of the multi-layer medicine trough, and rotating pallet stops are arranged at both ends of the export rotating pallet. The front end of the multi-layer medicine trough is arranged on the export electric eye, and the lower part of the export rotating pallet is provided with a back hinge and a pallet spring. The export rotating pallet is connected to the export width and narrow switching plate through the pallet spring. A plurality of cargo electric eyes are arranged at equal intervals on the outer side of the multi-layer medicine trough, and a medicine trough conveyor belt is also arranged inside the multi-layer medicine trough. The rear end of the multi-layer medicine trough is provided with a tail medicine box propulsion body, and the tail medicine box propulsion body is arranged above the medicine trough conveyor belt. The rear end of the multi-layer medicine trough is provided with a cargo display light, an export light, a replenishment light, a forward button, a backward button, a no cargo light and a replenishment key.

[0007] Furthermore, the plurality of groups of shelves may be arranged in hundreds or thousands of groups according to needs.

[0008] Furthermore, the multi-layer medicine trough is arranged within a height of 10 layers to facilitate replenishment.

[0009] Furthermore, the length is 6 meters, which ensures that 80% of the varieties of medicines in a box can be fully loaded into the medicine trough at one time, and the rear end of the multi-layer medicine trough can replenish medicines, and the front end of the multi-layer medicine trough can discharge medicines.

[0010] Furthermore, the width of the outlet of the multi-layer medicine trough is achieved by an outlet width-changing plate, ensuring that the outlet width is larger than one box of medicine and smaller than two boxes of medicine.

[0011] Furthermore, the elastic force of the support plate spring can be adjusted, and the elastic force of the support plate spring is greater than the weight of boxes of medicine.

[0012] Furthermore, a stepper motor is provided on one side of the sorting hand, and an output end of the stepper motor is connected to the sorting hand and drives the sorting hand to rotate.

[0013] Furthermore, an order collection box is provided at the bottom of a section of the running direction of the summary transmission belt, and the box medicines are transmitted to the order collection box through the summary transmission belt.

[0014] Furthermore, an order outbound verification box is provided on the composite packaging table, and the order outbound verification box receives the box medicines from the order collection box.

[0015] Furthermore, the composite packaging table performs order packaging operations and is used to place packaged orders.

[0016] The beneficial effects of the present invention are as follows: the core of the system is that the sorting process is automatically performed by highly intelligent sorting hands. Relying on advanced control systems and precision mechanical structures, it can simultaneously cope with the sorting tasks of multiple varieties or even dozens or hundreds of drugs, and maintain an extremely high accuracy rate throughout the whole process, which is stable at more than 99.9%. In terms of efficiency improvement, compared with traditional manual sorting, the efficiency improvement is more than 5 times, while greatly saving labor costs, and at least reducing labor input by 50%. From the overall operation level, the system not only significantly improves the speed and accuracy of drug sorting, but also optimizes the warehouse logistics process, providing solid and powerful technical support for large pharmaceutical companies to cope with complex and changeable market demands.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Unless otherwise defined, all professional and scientific terms used herein have the same meanings as those familiar to those skilled in the art. In addition, any methods and materials similar or equivalent to those described herein may be applied to the present invention. The preferred implementation methods and materials described herein are for demonstration purposes only and are not intended to limit the content of this application.

[0024] The experimental methods in the following examples are conventional methods unless otherwise specified, and the experimental materials used in the following examples are purchased from commercial channels unless otherwise specified.

[0025] Example

[0026] A system for automatically sorting multiple varieties of boxed medicines in a warehouse at the same time, comprising an order system 1, an order drive system 2, multiple groups of shelves 3 (hundreds or thousands of groups can be arranged as required), multi-layer medicine troughs 4 (arranged within 10 layers for easy replenishment), sorting arms 5, guide speed reduction cloth bags 6, a collection transmission belt 7 and a composite packaging table 8.

[0027] The multi-layer medicine trough 4 includes an outlet rotating support plate 401, which is arranged at the front end of the multi-layer medicine trough 4, and a rotating support plate stopper 403 is arranged at both ends thereof. An outlet electric eye 402 is also arranged at the front end of the multi-layer medicine trough 4. The outlet rotating support plate 401 plays a key transitional role, which facilitates the smooth exit of the medicine box from the medicine trough into the next link. The lower part of the outlet rotating support plate 401 is provided with a back hinge 406 and a support plate spring 405. The outlet rotating support plate 401 is connected to an outlet width switching plate 404 through the support plate spring 405. The outlet width switching plate 404 can adjust the width of the outlet of the multi-layer medicine trough 4, ensuring that the outlet width is greater than one box of medicine and less than two boxes of medicine, so that only one box of medicine can be accurately controlled to pass through the outlet each time, avoiding confusion caused by the simultaneous extrusion of multiple boxes of medicine. In addition, the elastic force of the support plate spring 405 can be adjusted, and its elastic force is greater than the weight of a box of medicine. This ensures that when the box of medicine is pushed out of the medicine trough and the outlet rotating support plate 401 is pushed open, the support plate spring 405 can provide sufficient supporting force to ensure that the outlet rotating support plate 401 opens normally. After the box of medicine leaves, the outlet rotating support plate 401 can quickly return to its original position by relying on the elastic force, which is convenient for subsequent use. At the same time, the outlet electric eye 402 can promptly detect whether there is a box of medicine at the outlet. When it is detected that there is no box of medicine, the medicine trough conveyor belt 408 will automatically move forward to replenish the medicine. Once the box of medicine reaches the position of the outlet electric eye 402 again, the conveyor belt will stop to ensure the orderly flow of medicine in the medicine trough.

[0028] The outer side of the multi-layer medicine trough 4 is equidistantly arranged with a plurality of cargo quantity electric eyes 407, which can monitor the quantity of medicines in the medicine trough in real time, and provide accurate data reference for replenishment and other operations. The multi-layer medicine trough 4 is also provided with a medicine trough conveyor belt 408, which is an important power source for the movement of medicines in the medicine trough, and pushes the medicines to move toward the exit direction. The rear end of the multi-layer medicine trough 4 is provided with a tail medicine box propulsion body 409, which is arranged above the medicine trough conveyor belt 408 and plays a key role in the replenishment operation. The rear end of the multi-layer medicine trough 4 is provided with a cargo quantity display light 410, an exit light 411, a replenishment light 412, a forward button 413, a reverse button 414, a no cargo light 415 and a replenishment key 416, each of which has a clear functional indication. For example, when the system is running, first fill the medicine box from the rear end of the medicine slot (you can also force the medicine box to be filled during operation). When the replenishment key 416 is pressed, the replenishment light 412 lights up, which means that the order work for this medicine slot is completed and priority is obtained. At this time, press the back key to get the rear medicine box propeller and start to replenish the medicine slot. Then you can use the forward key 413 to fill the medicine slot, or directly fill it in one piece, and then place the medicine box propeller close to the last medicine box to ensure that the last box of medicine can also be sorted out. Then press the forward key until the exit light 411 lights up, proving that the medicine box has arrived at the exit. Lift the replenishment key and the replenishment light 412 goes out, and the replenishment of this medicine slot is completed. Moreover, all varieties are slotted according to the medicine slot number corresponding to the system number, ensuring the orderliness and accuracy of the entire sorting process.

[0029] The length of the multi-layer medicine trough 4 is 6 meters. Such a length design can ensure that 80% of the varieties of medicines in a box can be fully loaded into the medicine trough at one time, and the medicines are replenished at the rear end of the medicine trough and discharged from the front end of the medicine trough. There is one medicine trough for each variety. When each medicine trough is placed on the shelf, the sorting end is 0.15 meters forward of the lower layer to ensure that the guide deceleration bag 6 is installed in an orderly manner, so that the boxed medicine can smoothly enter the guide deceleration bag 6 after leaving the medicine trough, further ensuring the continuity of the entire sorting process.

[0030] A stepper motor 501 is provided on one side of the sorting hand 5, and the output end of the stepper motor 501 is connected to the sorting hand 5 and drives the sorting hand 5 to rotate. During operation, the order drive system 2 receives an instruction and drives all the medicine slot sorting hands 5 in the corresponding order to work simultaneously according to the instruction. Two sorting hands 5 on each medicine slot move once (180 degrees, 0.5 seconds and 0.5 seconds). Through such regular movements, a box of medicine is pushed down from the medicine slot, and the box of medicine is forced to move to push the exit rotating support plate 401 until it leaves the support plate and then falls into the guide deceleration bag 6. The whole process is carried out at a speed of one box per second, and the variety with the largest number is sorted last, that is, all orders are sorted.

[0031] An order collection box 701 is provided at the bottom of a section in the running direction of the summary transmission belt 7, and the boxed medicines are transmitted to the order collection box 701 through the summary transmission belt 7. Then, the order collection box 701 is manually moved to the composite packaging table 8, and an order outbound verification box 801 is provided on the composite packaging table 8. The order outbound verification box 801 receives the boxed medicines in the order collection box 701, performs order packaging operation on the composite packaging table 8, and is used to place the packaged orders 802, thus completing the entire process of automatic sorting and packaging of multiple varieties of boxed medicines at the same time.

[0032] How it works

[0033] The system consists of an order system 1, an order drive system 2, multiple groups of shelves 3, multi-layer medicine troughs 4, sorting arms 5, guided deceleration bags 6, a collection conveyor belt 7 and a review and packaging table 8.

[0034] Before starting the system, it is necessary to ensure that all components are operating normally. The corresponding drugs are loaded into the multi-layer medicine slots 4 in sequence according to the drug varieties. Each variety corresponds to a medicine slot, and the length of the medicine slot is 6 meters, which can ensure that 80% of the varieties of drugs in a box can be loaded at one time. At the same time, the elastic force of the lower support plate spring 405 of the outlet rotating support plate 401 is adjusted to be greater than the weight of a box of drugs, and the outlet width switching plate 404 is set to the initial width to ensure that the outlet width is greater than one box and less than two boxes.

[0035] At the beginning of the work, first fill the medicine boxes from the rear end of the medicine slot. If necessary, you can also force the filling of medicine boxes during the operation. When the replenishment button is pressed, the replenishment light 412 lights up, the work of this medicine slot order is completed and priority is obtained, press the back button, remove the tail medicine box pusher 409, and the staff will fill the medicine slot with replenishment. You can choose to use the forward button 413 to fill the medicine slot as needed, or directly fill it in one piece, and then place the medicine box pusher close to the last medicine box to ensure that the last medicine box can also be sorted out. Press the forward button until the exit light 411 lights up, indicating that the medicine box has arrived at the exit. Lift the replenishment button and the replenishment light 41 goes out, and the replenishment of this medicine slot is completed. At this point, all varieties have been loaded into the slot according to the medicine slot number corresponding to the system number.

[0036] After the order is placed, the order drive system 2 receives the instruction and drives all the medicine slot sorting hands 5 in the corresponding order to work simultaneously according to the instruction. Driven by the stepper motor 501, the two sorting hands 5 on each medicine slot move once at a rhythm of 180 degrees, 0.5 seconds to rotate and stop for 0.5 seconds, pushing a box of medicine down from the medicine slot. The box of medicine is pushed open by the exit rotating support plate 401. Since the elastic force of the support plate spring 405 is greater than the weight of a box of medicine, the support plate opens to allow the box of medicine to pass through. After the box of medicine leaves the exit rotating support plate 401 (at this time, the exit rotating support plate 401 quickly returns to its original position under the action of the support plate spring 405), the exit electric eye 402 detects that there is no box of medicine, triggering the medicine slot conveyor belt 408 to move forward to replenish the medicine. Once the box of medicine reaches the exit electric eye 402 position again, the conveyor belt stops. After the box medicine leaves the exit rotating pallet 401, it falls into the guide deceleration bag 6 and slides along the bag to the collection conveyor belt 7. The whole process is carried out steadily at a speed of one box per second and follows the rule that the variety with the largest number is sorted last, ensuring that all medicines in an order are sorted.

[0037] When an order is completely sorted, the collection conveyor belt starts running to transport all the medicines in this order to the order collection box 701. Then the order collection box 701 is manually moved to the review and packaging table 8. The order outbound review box 801 on the review and packaging table 8 receives these boxes of medicines for manual review. Then the staff performs the order packaging operation here. After completion, the packaged order 802 is placed at the designated position of the composite packaging table 8, waiting for subsequent transportation or warehousing. At this point, the entire sorting and packaging process is completed, and the system is ready to proceed to the next order task.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0039] The present invention and its implementation methods are described above, which is not restrictive. The drawings are only one of the implementation methods of the present invention, and the actual application is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
