[0002] As the number of patients in major hospitals increases, the demand for medicines also increases. Each hospital needs to increase the area of ​​the pharmacy and the number of staff in the pharmacy to meet the increasingly busy work, which leads to a sharp increase in costs. At present, the medicines stored in the pharmacy are stored in batches according to the category of medicines. After the doctor prescribes the medicine and charges, the patient hands over the medicine prescription to the pharmacy, and the pharmacist in the hospital pharmacy puts the corresponding medicine on the tray according to the medicine prescription, and sends the tray to the medicine pick-up window to complete the delivery of the medicine.

[0003] However, when faced with a large number of prescriptions to be picked up, this method of dispensing requires the pharmacist to take out the corresponding drugs from the drug storage area according to the prescriptions, and deliver the taken-out drugs to the corresponding drug pickup windows to give them to the patients. This requires the pharmacist to constantly travel back and forth between the drug storage area and the drug pickup windows, which is labor-intensive and has low work efficiency.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention transports an empty tray to the pharmacist by setting a first conveyor belt, and raises the tray to the top of the second conveyor belt through a lifting frame, so that the empty tray stays on the top of the placement component.

[0020] 3. In the present invention, as the movable roller rolls on the top of the buffer pad, the T-frame rotates at the lower end of the buffer frame, and the T-frame presses one end of the movable inner rod, so that the movable inner rod presses the internal return spring inside the rotating sleeve, thereby achieving buffering when the fixed frame is tilted, avoiding vibration of the tray on the top of the fixed frame, and preventing damage to the bottled medicines due to collision.

[0021] 4. When the present invention moves an empty pallet to between the pressing rollers via the first conveyor belt, the rotating motor controls the rotating block to rotate, causing the rotating block to rotate and pull the moving frame via the rotating support rod, causing the moving frame to slide on the top of the sliding track, causing the pressing rollers to move towards each other, thereby limiting and correcting the empty pallet, preventing the empty pallet from tilting and causing the pallet to slip off the first conveyor belt.

[0022] 5. The present invention controls the extension and retraction of the electric telescopic rod to make the rotating rod rotate on the side of the supporting frame. When the rotating rod rotates, it pushes the fixed roller to move inside the arc groove, thereby controlling one end of the third conveyor belt to rise and fall. When the tray is transported to the side of the pharmacist at the window, it can be automatically transported to different heights according to the height of the pharmacist, which is convenient for the pharmacist to take the tray and has high flexibility.

[0041] Second embodiment

[0042] As attached Figure 1 To Attachment Figure 4 , attached Figure 6 and attached Figure 7In one embodiment of the present invention, when the fixed handle 45 is pulled to make the movable rod 43 slide inside the support block 42, the fixed rack 413 moves to the top of the fixed gear 482, and the fixed gear 482 engages with the fixed rack 413, so that the fixed gear 482 drives the fixed frame 48 to rotate, so that the empty tray is tilted at a certain angle, which is convenient for the pharmacist to place the medicine inside the empty tray. At the same time, fixed gears 482 are provided at both ends of the fixed frame 48, so that the fixed frame 48 can be tilted in two directions on the top of the fixed plate 41, which is convenient for the pharmacist to place the medicine and improves the convenience of placing the conveying device.

[0043] As attached Figure 7 As shown, the placement component 4 includes a fixed plate 41 fixedly installed on the upper end of the fixed frame 11, support blocks 42 are fixedly installed at both ends of the top of the fixed plate 41, a movable rod 43 is movably sleeved inside the support block 42, fixed blocks 44 are fixedly installed on both sides of the movable rod 43, fixed handles 45 are fixedly installed on the sides of the fixed block 44, connecting blocks 411 are fixedly installed on the other two sides of the top of the fixed plate 41, roller frames 46 are fixedly installed on the sides of the connecting blocks 411 on both sides, and a plurality of support rollers 47 are rotatably installed inside the roller frames 46.

[0044] Buffer blocks 414 are fixedly installed at both ends of the side of the roller frame 46 , a groove 412 is opened on the top of the connecting block 411 , and a fixing frame 48 is arranged on the top of the fixing plate 41 .

[0045] In this embodiment, when the fixed handle 45 is pulled, the movable rod 43 slides inside the support block 42. At this time, the fixed rack 413 moves to the top of the fixed gear 482. The fixed gear 482 engages with the fixed rack 413, and the fixed gear 482 drives the fixed frame 48 next to the pulled fixed handle 45 to rotate inside the groove 412. The fixed gear 482 away from the pulled fixed handle 45 is disengaged from the inside of the groove 412, so that the empty tray is tilted at a certain angle, which is convenient for the pharmacist to place the medicine inside the empty tray. At the same time, fixed gears 482 are provided at both ends of the fixed frame 48, so that the fixed frame 48 can be tilted in two directions at the top of the fixed plate 41.

[0046] As attached Figure 8 and attached Fig. 9As shown, baffles 49 are fixedly installed on both ends of the top of the fixed frame 48, and fixed gears 482 are fixedly installed on both sides of the baffle 49. One side of the fixed gear 482 is rotatably installed inside the groove 412.

Since the right side of the buffer block 414 is an inclined surface and the left side of the buffer block 414 is an arc shape, as the movable roller 486 rolls on the top of the buffer block 414, the T-frame 485 rotates at the lower end of the buffer frame 481, and the T-frame 485 presses on one end of the movable inner rod 484, so that the movable inner rod 484 is pressed against the internal return spring inside the rotating sleeve 483, thereby achieving buffering when the fixed frame 48 falls over, avoiding vibration of the tray on the top of the fixed frame 48, and preventing damage to the bottled medicines due to collision.

[0049] Third embodiment

[0050] As attached Figure 1 To Attachment Fig. 9 In one embodiment of the present invention, after the pharmacist gives the medicine to the patient, the pharmacist pushes the empty tray from the feed plate 52 to the top of the first conveyor belt 13. When the empty tray is moved to between the pressing rollers 59 through the first conveyor belt 13, the rotating motor 54 controls the rotating block 55 to rotate, so that the rotating block 55 rotates and pulls the moving frame 58 through the rotating support rod 56, so that the moving frame 58 slides on the top of the sliding track 57, and the pressing rollers 59 move towards each other, thereby limiting and correcting the empty tray to prevent the empty tray from tilting and causing the tray to slide off the first conveyor belt 13.

[0051] As attached Figure 5As shown, the straightening device 5 includes a feed rack 51, and feed plates 52 are fixedly installed at both ends of the top of the right side of the feed rack 51, and a fixed support plate 53 is fixedly installed on the left side of the feed rack 51, and a rotating motor 54 is fixedly installed on the bottom of the fixed support plate 53, and a rotating block 55 is fixedly installed on the top of the rotating motor 54.

A pressing roller 59 is rotatably installed on the top of the moving frame 58, and the interior of the moving frame 58 is rotatably connected to one end of the rotating support rod 56.

[0052] Among them, the two side feed plates 52 are respectively located on both sides of the right end of the first conveyor belt 13, and their height is flush with the first conveyor belt 13. The rotating support rod 56 and the rotating block 55 are rotatably installed at the bottom of the first conveyor belt 13, and the pressing roller 59 is movably installed on both sides of the first conveyor belt 13.

[0053] The sum of the lengths of the second conveyor belt 17 , the placement component 4 and the third conveyor belt 19 is the same as the length of the first conveyor belt 13 .

[0054] In this embodiment, the rotating block 55 is controlled by the rotating motor 54 to swing back and forth on the top of the fixed support plate 53, so that the rotating block 55 rotates ninety degrees clockwise on the top of the fixed support plate 53, and then rotates ninety degrees counterclockwise. This reciprocating motion causes the rotating block 55 to rotate, and then controls the moving frame 58 to move back and forth on the sliding track 57, and the pressing rollers 59 on both sides move toward each other to correct the empty tray.

[0055] Fourth embodiment

[0056] As attached Figure 1 To Attachment Fig.10 This is an embodiment of the present invention. By controlling the extension and retraction of the electric telescopic rod 26, the rotating rod 23 is rotated on the side of the supporting frame 21. When the rotating rod 23 rotates, it pushes the fixed roller 24 to move inside the arc groove 22, and then controls one end of the third conveyor belt 19 to rise and fall. When the tray is transported to the side of the pharmacist at the window, it can be automatically transported to different heights according to the height of the pharmacist, which is convenient for the pharmacist to take the tray, and has high flexibility.

[0057] As attached Fig.10As shown, the adjustment component 2 includes a support frame 21, which is fixedly installed on the right side of the fixed frame 11. Arc grooves 22 are provided on both sides of the upper end of the support frame 21. Rotating rods 23 are rotatably installed on the upper ends of both sides of the support frame 21. An electric telescopic rod 26 is rotatably installed on the upper end of the support frame 21. One end of the electric telescopic rod 26 is rotatably installed on one side of the rotating rod 23. One end of the rotating rod 23 is fixedly connected to a fixed roller 24, and the fixed roller 24 is slidably installed inside the arc groove 22. The upper end of the support frame 21 is fixedly connected to a positioning frame 25.

[0058] In this embodiment, by controlling the extension and retraction of the electric telescopic rod 26, the rotating rod 23 is rotated on the side of the support frame 21. When the rotating rod 23 rotates, the fixed roller 24 is pushed to move inside the arc groove 22, and the height of the conveying terminal of the third conveyor belt 19 is adjusted according to the height of the fixed roller 24, so as to facilitate the pharmacist to take it.

[0059] Working principle of the present invention: when in use, the pharmacist at the window places the medicine list in an empty tray, pushes it to the top of the first conveyor belt 13 through the feed plate 52, and when the empty tray is moved between the pressing rollers 59 through the first conveyor belt 13, the rotating motor 54 controls the rotating block 55 to rotate, so that the rotating block 55 rotates and pulls the moving frame 58 through the rotating support rod 56, so that the moving frame 58 slides on the top of the sliding track 57, so that the pressing rollers 59 move toward each other, and the empty tray is limited and corrected to avoid the empty tray from tilting and causing the tray to slide off the first conveyor belt 13;

[0060] When the first conveyor belt 13 transports the empty tray to the lifting device 3, the empty tray slides into the inside of the lifting frame 311, and the photoelectric sensor 14 detects the passage of the empty tray. Through the electrical signal, the lifting motor 33 is controlled to start, so that the lifting screw 34 rotates inside the lifting slot 35, and the lifting plate 36 is controlled to rise, so that the lifting frame 311 drives the empty tray to rise. Due to the limit of the rotating wheel 313 inside the limiting slot 15, when the rotating wheel 313 rises to the top of the limiting slot 15, the lifting frame 311 rotates at the upper end of the lifting plate 36 through the limit of the limiting slot 15, so that the support rod 310 rotates, the lifting block 39 descends, and the pressing spring 38 is pressed, the lifting frame 311 rotates and is in a tilted state, so that the empty tray slides to the top of the second conveyor belt 17, and then the tray moves to the top of the placement component 4. Since there is no power transmission on the placement component 4, the tray with the medicine list will automatically stop at the top of the placement component 4.

[0061] At this time, the fixed handle 45 is pulled to make the movable rod 43 slide inside the support block 42. At this time, the fixed rack 413 moves to the top of the fixed gear 482. The fixed gear 482 meshes with the fixed rack 413, and the fixed gear 482 drives the fixed frame 48 next to the pulled fixed handle 45 to rotate inside the groove 412. The fixed gear 482 away from the pulled fixed handle 45 is separated from the inside of the groove 412, so that the empty tray is tilted at a certain angle, which is convenient for the pharmacist to place the medicine inside the empty tray. At the same time, fixed gears 482 are provided at both ends of the fixed frame 48, so that the fixed frame 48 can be tilted in two directions on the top of the fixed plate 41, which is convenient for the pharmacist to place the medicine.

[0062] After the medicines are placed, the tray containing the medicines is pushed and transported to the medicine dispensing window through the third conveyor belt 19. The pharmacist at the window takes the tray off and puts it in the list of other patients again, and repeats the above steps to complete the delivery of the medicines;

[0063] In addition, by controlling the extension and retraction of the electric telescopic rod 26, the rotating rod 23 is rotated on the side of the supporting frame 21. When the rotating rod 23 rotates, the fixed roller 24 is pushed to move inside the arc groove 22, thereby controlling one end of the third conveyor belt 19 to rise and fall. When the tray is transported to the side of the pharmacist at the window, it can be automatically transported to different heights according to the height of the pharmacist, which is convenient for the pharmacist to take the tray, and has high flexibility.
