Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to an automatic medicine box sorting system and a sorting method thereof. Background Art

[0002] The main way of sorting medicines in hospital pharmacies and medical stores is to sort them in pieces. The domestic technical means in this field are relatively backward, and the relevant technologies are not intelligent and reliable enough. They are mainly based on manual selection, and manual electronic barcode scanning guns are used to scan and record the chaotic medicine boxes for sorting. This selection method is not only inefficient, labor-intensive, and prone to errors, but also leads to many conflicts between doctors and patients in society. At present, with the improvement of my country's comprehensive national strength and the development of medical and health care and social security, the pace of informatization construction of medical institutions is accelerating, and the demand for automatic drug sorting technology is becoming more and more urgent. To this end, we propose an automatic sorting system for medicine boxes, which can realize automatic arrangement of medicine boxes and further realize automatic scanning and automatic vending. Compared with traditional manual operations, it has high production efficiency, good effect, and low production cost, and can be widely used in the field of automatic drug vending. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic medicine box sorting system and a sorting method thereof, and the technical problem to be solved is that in the existing medicine box sorting method, the disordered medicine boxes are manually picked up and sorted, and the operation efficiency is low. The automatic arrangement of medicine boxes is realized, and the operation efficiency is high.

[0004] The present invention is achieved through the following technical solutions:

[0005] An automatic medicine box sorting system and a sorting method thereof include a rotating drum, a driving device, and a transmission device. The circumferential wall of the rotating drum is provided with a plurality of notches connected to the interior of the rotating drum, and the circumferential inner wall of the rotating drum is provided with a plurality of protrusions, which are located beside the notches. The rotating drum is connected to the driving device through the transmission device, and the driving device drives the rotating drum to rotate.

[0006] In the above structure, the drum is a part that realizes the orderly arrangement of scattered medicine boxes, which is realized by the rotation of the drum. The medicine boxes fall from the notches by opening a plurality of notches connected to the inside on the circumferential inner wall of the drum and a plurality of protrusions arranged on the circumferential inner wall. When the drum rotates, by controlling the rotation direction of the drum, the medicine boxes rotate along the rotation direction and fall into the notches under the action of the protrusions when passing through the notches. The protrusions on the circumferential inner wall of the drum have a form, and the medicine boxes are arranged in an orderly manner by the combined action of a plurality of protrusions and notches. The rotation of the drum is driven by a driving device, and the two are connected by a transmission device.

[0007] Furthermore, the driving device includes a stepping motor and a reducer. By selecting the reducer, the rotation speed of the drum is made more stable. Furthermore, the reducer can be a 1:15 reducer.

[0008] Furthermore, the transmission device includes a conveyor belt, a disc, and a driving pulley. The disc is connected to the rotating drum, and the driving pulley is arranged on the driving device. The disc and the driving pulley are both matched with the conveyor belt.

[0009] Furthermore, the notch is an inclined notch, and the specific inclined notch is a right-angled trapezoid. By setting the inclined notch, the medicine boxes will flow to the notch in sequence due to gravity and fall from the notch.

[0010] Furthermore, the protrusions include protrusions of various forms, one of which is a row of evenly arranged protrusion plates, the inclination direction of the protrusions is opposite to the inclination direction of the inclined grooves, and another protrusion is an arcuate protrusion arranged along the inner wall of the circle, the plan view of the arcuate protrusion and the inner wall of the circle where the arcuate protrusion is located after unfolding is a rectangle, the arcuate protrusion is the diagonal of the rectangle, and the medicine box flows into the notch along the arcuate protrusion.

[0011] Furthermore, it also includes a conveying device, which includes a conveying motor, a conveyor belt, a driving roller, and a driven roller. The output shaft of the conveying motor is connected to the driving roller, and the driving roller and the driven roller are both matched with the conveyor belt. The conveying device is arranged below the gap. When the medicine boxes fall from the gap, the medicine boxes are arranged in order on the conveyor belt and fall above the conveyor belt. Then the conveyor belt transports the medicine boxes to the coding device.

[0012] Furthermore, a detection device is also included, the detection device includes an infrared sensor, a cylindrical shell, and a controller. The cylindrical shell wraps the rotating drum, and a rectangular notch is opened on the circumferential wall of the cylindrical shell. The infrared sensor is arranged at the rectangular notch of the cylindrical shell, and the infrared sensor is connected to the controller, and the controller is connected to the driving device. When a medicine box goes out of the notch of the rotating drum, the conveyor belt will transport it to a designated position, and the infrared sensor arranged at the notch of the rotating drum will receive a signal, and then the controller controls the driving device to stop the rotating drum from rotating, thereby preventing multiple medicine boxes from flowing out at the same time.

[0013] Furthermore, it also includes a counting device, which includes a Hall element and a magnetic sheet. The magnetic sheet is arranged on the outer side of the circumferential wall of the drum, and the Hall element is arranged on the circumferential inner wall of the drum shell. Every time the drum rotates one circle, the Hall element senses once and the magnetic sheet records once. When the infrared sensor is not working, the count of the Hall sensor will not be reset, but will continue to record. When a certain value is recorded, the machine will automatically stop; this design is to facilitate operation and detection, reduce the operation steps of workers, and the equipment can automatically stop when there is no medicine box in the drum.

[0014] A sorting method for an automatic medicine box sorting system

[0015] The specific steps are as follows:

[0016] S. Place the medicine box into the rotating drum;

[0017] S, start the switch, the driving device drives the transmission device to rotate, the transmission device drives the drum to rotate, and the sorting starts; when the driving device is started, the conveying device is started;

[0018] S. The detection device is started. When the infrared sensor detects that the medicine box falls from the gap, the controller controls the drum to pause. After the pause, the drum continues to rotate; when the infrared sensor does not detect that the medicine box falls from the gap, the drum continues to rotate;

[0019] S. The counting device detects whether the number of idling times of the drum reaches the set value. When the set value is reached, the controller controls the drum to stop running.

[0020] The present invention has the following beneficial effects:

[0021] 1. Through the drum, driving device, transmission device, and the notches and protrusions on the inner wall of the drum, the medicine boxes fall from the notches under the action of gravity during the rotation of the drum, thereby realizing automatic sorting of the medicine boxes with high operating efficiency.

[0022] 2. Through the establishment of the conveying device, the medicine boxes falling from the gap are arranged in order on the conveyor belt. By controlling the conveyor belt speed, the production efficiency of the device is improved, and the medicine boxes are transported to the coding device for coding.
