[0001] The present invention relates to the technical field of medicine packaging, in particular to a special intelligent packaging device for medicines. Background Art

[0002] Hospital pharmacies or retail pharmacies are faced with a wide variety of drugs and their placement is scattered. The traditional sales and drug collection process relies on manual operations by pharmacy staff, who walk around the pharmacy to find and pick up drugs according to prescriptions, and then identify and scan them before packaging and distributing them. At present, in the existing drug packaging process, it is difficult to efficiently adjust the single and sequential delivery of a large number of drugs during the drug delivery process, resulting in low drug delivery efficiency and recognition efficiency, resulting in the need to start and stop the delivery of drugs multiple times, which easily causes the position of the drugs to change, resulting in a decrease in the recognition accuracy of the drugs, affecting the distribution and packaging of drugs.

[0003] Therefore, it is necessary to provide a special intelligent packaging device for medicines to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0023] Reference Figure 1-Figure 5The present invention provides a technical solution: a special intelligent packaging equipment for medicines, comprising a frame 1, a conveying belt 2 is installed on the frame 1, a strip groove 21 perpendicular to the conveying direction is provided on the surface of the conveying belt 2, a retaining device 3 is installed in the strip groove 21, the retaining device 3 comprises two symmetrically arranged retaining components 31, the retaining component 31 comprises a strip shell guide rail 32, a slide seat 1 34 and a slide seat 2 38 are respectively slidably arranged in the strip shell guide rail 32, a retaining strip 35 is hinged on the slide seat 1 34, a slideway 351 is provided on the retaining strip 35, and the slideway 3 A sliding shaft 36 is slidably mounted in the middle of the conveyor belt 51, and a connecting rod 37 is hingedly mounted on the sliding shaft 36. The connecting rod 37 is also hingedly connected to the second slide seat 38. A permanent magnet 39 is also mounted on the second slide seat 38. An electromagnet 310 corresponding to the permanent magnet 39 is mounted on one end of the strip guide rail 32. The other end of the strip guide rail 32 is connected to the first slide seat 34 through a spring 33. A front frame 4 and a rear frame 7 are sequentially mounted along the conveying direction of the conveyor belt 2. A guiding device 5 is mounted on the front frame 4, and an identification device 71 is mounted on the rear frame 7. After the retaining device 3 is embedded in the strip groove 21, it is connected to the first slide seat 34. The surface of the conveyor belt 2 is flush; when the retaining assembly 31 is in operation, the electromagnet 310 is started to generate a magnetic force that repels the permanent magnet 39, pushing the permanent magnet 39 to move, and the permanent magnet 39 pushes the connecting rod 37, and the connecting rod 37 pushes the retaining bar 35 to rotate on the slide 34, and at the same time, drives the slide 34 to move until the retaining bar 35 contacts and clamps the side of the medicine. By starting multiple retaining devices 3, the position of the medicine can be adjusted while retaining the medicine. For example, when the medicine is transported on the conveyor belt 2 at an angle, the retaining bar 35 is close to the medicine. During the process of close contact with the medicine, the first retaining strip 35 that comes into contact will have the effect of pushing the position of the medicine, and so on, until the side of the medicine is completely in contact with the retaining strip 35 within the range contained in the side of the medicine, thereby completing the retention of the medicine and the correction and adjustment of the position of the medicine, thereby preventing the medicine from sliding on the surface of the conveyor belt 2 when the conveyor belt 2 is started and stopped intermittently, thereby affecting the accuracy of the identification device 71 in identifying the medicine; and as a preferred embodiment, the moving distance of the retaining strip 35 can also be adjusted by adjusting the size of the magnetic force of the electromagnet 310.

[0024] In this embodiment, a limit stop bar 341 is provided on the slide 1 34 to limit the rotation angle of the retaining bar 35. In this embodiment, the limit stop bar 341 can limit the rotation of the retaining bar 35 by 90°, that is, the retaining bar 35 is rotated to be perpendicular to the surface of the conveyor belt 2. It should be noted that when the retaining component 31 is started, the retaining bar 35 is preferentially pushed by the connecting rod 37 to rotate to 90°, and then, it moves synchronously with the slide 1 34 and the slide 2 38 to approach the side contacting the medicine.

[0025] In this embodiment, a buffer washer 3101 is provided on the electromagnet 1 310 for buffering the movement of the permanent magnet 39, so as to reduce the collision effect between the permanent magnet 39 and the electromagnet 1 310 during the resetting process.

[0026] In this embodiment, a front infrared sensor 6 and a rear infrared sensor 8 are respectively provided on the rear sides of the front frame 4 and the rear frame 7. In this embodiment, the front infrared sensor 6 is used to trigger the start of the retaining device 3, and the rear infrared sensor 8 is used to trigger the closing of the retaining device 3. Specifically, when the retaining device 3 on the upper side of the conveyor belt 2 passes the front infrared sensor 6, the retained device 3 that has passed is triggered and started to retain the medicine so that the identification device 71 can identify and process it. When the retaining device 3 on the upper side of the conveyor belt 2 passes the rear infrared sensor 8, the retained device 3 that has been triggered and started is triggered to close, so that the identified medicine can be conveyed to the packaging box arranged outside.

[0027] In this embodiment, the guiding device 5 includes a plurality of flow-blocking assemblies 51 arranged at vertical intervals, and the flow-blocking assembly 51 includes a rotating plate 52 rotatably mounted on the front frame 4, a steel block 54 is mounted on the upper end of the rotating plate 52, and an electromagnet 2 55 corresponding to the steel block 54 is also mounted on the front frame 4, and a column 53 is mounted on the lower end of the rotating plate 52. In this embodiment, when the electromagnet 2 55 is turned off and the medicine touches the column 53, the medicine can push the column 53 to rotate and pass through the guiding device 5. When the electromagnet 2 55 is started, the electromagnet 2 55 is attracted to the steel block 54, and the column 53 can intercept the flow of medicine on the conveyor belt 2.

[0028] In this embodiment, the rotating plate 52 is further connected to the front frame 4 via a reset torsion spring 56, so that after the medicine pushes the rotating plate 52 to rotate, the rotating plate 52 can reset itself quickly.

[0029] In the present embodiment, the connecting line of the lower ends of the columns 53 in the plurality of the baffle assemblies 51 is an obtuse-angle structure. When there are drugs placed overlapping in a lateral position on the conveying belt 2 in a direction perpendicular to the conveying direction, the intercepted drugs are guided and moved to the baffle assembly 51 in the middle area through the interaction between the columns 53 and the conveying belt 2, thereby facilitating the subsequent control of the drugs through the columns 53 by the guiding device 5, avoiding the subsequent conveyance of drugs placed overlapping in a lateral position on the conveying belt 2, and avoiding the intercepted drugs from flowing out to the side of the conveying belt 2, thereby improving the working efficiency and working accuracy.

[0030] In this embodiment, the upper end of the column rod 53 is rotatably connected to the lower end of the rotating plate 52 to improve the smoothness and efficiency of guiding the movement of the medicine.

[0031] In this embodiment, a pressure sensor 521 for monitoring the pressure of the column 52 is installed on the rotating plate 52. When the column 52 touches the medicine, the pressure sensor 521 can detect that the medicine touches the column 52. The pressure sensor 521 feeds back to the electromagnet 2 55 to control the start and stop of the electromagnet 2 55.

[0032] In specific implementation, it includes the following steps:

[0033] Step 1: The conveyor belt 2 in front of the front rack 4 is used to input the medicines to be packaged, and the medicines can be placed at will, thereby improving the efficiency of putting the medicines on the conveyor belt 2;

[0034] Step 2: In the initial state, the second electromagnet 55 in the guide device 5 is in the start-up state, that is, the second electromagnet 55 absorbs the steel block 54. When the medicine on the conveyor belt 2 is transported to the guide device 5 area, the medicine touches the column 52, and the corresponding pressure sensor 521 feedback triggers the corresponding second electromagnet 55 to close. The second electromagnet 55 has no adsorption effect on the steel block 54, and the medicine can push the column 52 to tilt, so that the medicine is transported with the conveyor belt 2. After the medicine passes through the guide device 5, the column 52 is reset, and the second electromagnet 55 is triggered to open again;

[0035] Step 3: After passing through the front infrared sensor 6, the front infrared sensor 6 triggers the starting retention device 3 to calibrate and retain the medicine;

[0036] Step 4: Identification and processing by the identification device 71;

[0037] Step 5: After passing through the rear infrared sensor 8, the rear infrared sensor 8 triggers the closing of the retaining device 3 to facilitate the delivery and packaging of the medicine.

[0038] In this embodiment, in step 2, first of all, it is necessary to explain that when a drug passes through the guiding device 5, the phenomenon that a drug touches the column 52 it covers is that it touches the column 52 of the drug at the first time, and then the transported drug will touch the adjacent and continuous column 52 in sequence. Secondly, when the drug is transported on the conveying belt 2, the following operation procedures are performed. Procedure 1 is to monitor the first time that the column 52 touches the drug. After the column 52 is touched for the first time, the column 52 touched by the transported drug is presented as touching the adjacent and continuous situation in sequence, which indicates that in the process of this drug transportation, there are no other drugs placed in a horizontal position overlapping with the conveying direction in the direction perpendicular to the conveying direction. Procedure 2 is that after the column 52 is touched for the first time, the column 52 touched by the transported drug is presented as touching the adjacent and continuous situation in sequence. 2. If the drugs are touched in sequence in an adjacent and continuous manner, and in this process, the triggered rods 52 appear with gaps, it indicates that in the process of drug delivery, there are other drugs that are overlapped in the horizontal position in the direction perpendicular to the delivery direction. Therefore, when the triggered gapped rods 52 appear at any time in this process, the corresponding rods 52 stop feeding back to the corresponding electromagnet 2 52, that is, the triggered gapped rods 52 intercept the drugs here until the delivery of the drugs that touch at the first time is completed, and then the procedure 1 is performed; thereby efficiently controlling the drugs to avoid the presence of other drugs that are overlapped in the horizontal position in the direction perpendicular to the delivery direction, and ensuring that the drugs are transported and packaged after being identified one by one by the identification device 71.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the invention, which should be covered by the protection scope of the present invention.
