Description
Technical Field
[0001] The invention relates to the technical field of elderly-assisting machinery, in particular to a turnover-type medicine dispensing device suitable for bottled tablets. Background Art
[0002] In today's daily life, almost everyone needs to take medicine to restore their health at some point in time. However, in most families in China, the organization and placement of medicines rely heavily on manual memory and labor. Among them, the elderly have a greater demand for taking medicine and are also one of the main target groups for medicines. However, some elderly people may forget to take medicine or forget where to put the medicine due to memory loss and other reasons. Even some elderly patients with hand diseases find it difficult to unscrew the bottle cap to take medicine. Existing elderly-assisting machines are far from meeting the elderly's needs for taking medicine on time, automatically dispensing medicine, and controlling the amount of medicine taken, and their popularity is far from enough. Therefore, the present invention is designed to realize functions such as mobile phone WiFi on-time reminders, hands-free opening of medicine bottles, and automatic classification and dispensing of medicines to better assist the elderly in taking medicine. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, the present invention provides a flip-type medicine dispensing mechanism suitable for bottled tablets, which has the advantages of small size, low production cost, easy use, high working efficiency and good stability.
[0004] The technical solution adopted by the present invention to solve its technical problem is:
[0005] A flip-type medicine dispensing mechanism suitable for bottled tablets comprises a box, a medicine box, a photoelectric switch, a chain-driven medicine storage mechanism, a flip-type gradient hole medicine dispensing mechanism and a stepping motor bottle cap screwing module. The chain-driven medicine storage mechanism, the flip-type gradient hole medicine dispensing mechanism and the stepping motor bottle cap screwing module are mounted on the box. The chain-driven medicine storage mechanism controls the position of the medicine bottle. The medicine bottle first moves to the bottom of the stepping motor bottle cap screwing module. After the bottle cap is screwed off, the medicine bottle moves to the bottom of the flip-type gradient hole medicine dispensing mechanism. The servo motor chain drives the medicine bottle. The entire flip-type gradient hole medicine dispensing mechanism, together with an in-line damping shaft, a tray, a shaking table clamp, and the medicine bottle, flips 180 degrees so that the bottle mouth faces downward to dispense the medicine.
[0006] Furthermore, the chain-driven medicine storage mechanism includes a servo motor 1, a sprocket A, a chain, a straight damping shaft, a tray, a shaking table clamp, a medicine bottle, a driven shaft, a bearing and a sprocket B. The retractable shaking table clamp clamps the medicine bottle placed on the tray, and the tray is connected to the chain through a straight damping shaft. The servo motor is controlled to drive the sprocket to rotate, and the sprocket drives the chain to move to drive the tray. The servo motor is controlled to rotate and the tray and the medicine bottle are brought to two designated positions in turn, namely, below the two-way bottle cap screwing mechanism of the stepping motor bottle cap screwing module and below the oblique mouth medicine discharge cap of the gradient hole medicine discharge mechanism of the flip gradient hole medicine discharge mechanism.
[0007] Furthermore, the stepper motor bottle cap tightening module includes a guide shaft, a stepper motor, a screw rod, a screw rod nut, a connecting plate, a bidirectional bottle cap tightening mechanism, a bilateral clamp with a rack, a bilateral clamp with a rack, a gear, a fixed crossbeam plate, a bottle cap tightening housing, a steering wheel C, a servo C, an L-shaped bracket B and a multi-functional bracket C. When the medicine bottle is transferred to the bottom of the bidirectional bottle cap tightening mechanism of the stepper motor bottle cap tightening module by the chain drive medicine storage mechanism, the stepper motor bottle cap tightening module starts to move until the fixed crossbeam plate of the bidirectional bottle cap tightening mechanism is against the bottle cap, and the bidirectional bottle cap tightening mechanism executes the bottle cap unscrewing process and resets after the execution is completed.
[0008] The flip-type gradient hole medicine dispensing mechanism includes a base, a multi-functional bracket A, a steering gear A, a steering wheel A, a steering wheel connector, a linear motor, a linear motor module connector and a gradient hole medicine dispensing mechanism. When the gradient hole medicine dispensing mechanism starts to perform the medicine dispensing action, the steering gear B drives the gradient hole medicine dispensing mechanism to move. After dropping a specified target number of drops, the gradient hole medicine dispensing mechanism is closed. After the medicine is taken, the steering gear steering wheel A rotates 180° in the opposite direction, causing the flip-type gradient hole medicine dispensing mechanism to flip back, and the linear motor moves upward to the initial position.
[0009] The gradient hole medicine discharging mechanism includes an oblique mouth medicine discharging cover installed on the medicine discharging gradient hole shell, the gradient hole turntable cooperates with it and is connected to the steering wheel B, a height-limited pre-push medicine trough, a long connecting plate and a short connecting plate are installed on the medicine discharging gradient hole shell, a micro push-pull electromagnet is installed on the long connecting plate, an electromagnet medicine pushing connector is installed on the micro push-pull electromagnet and cooperates with the height-limited concave groove of the height-limited pre-push medicine trough, a steering gear B is connected to the steering wheel B, a multifunctional bracket B is connected to the steering gear B, and an L-shaped connecting bracket A is installed on the multifunctional bracket B; the rotation of the steering gear B changes the size of the hole between the gradient hole turntable and the oblique mouth medicine discharging cover, and the movement between the electromagnet medicine pushing connector and the height-limited pre-push medicine trough enables the tablets to fall out one by one.
[0010] The lower part of the oblique-mouth medicine outlet cover is a circular stretched baffle ring, which is used to drive the rotation of the bottle medicine - a straight damping shaft. There is an oblique hole with a portion cut off in the center. The cut-off portion of the oblique hole is connected with an elastic material combination. The lower bottom surface of the oblique hole, that is, the plane where the baffle ring is located, cuts a thin gap with the baffle ring. The lower bottom surface of the shell wrapped outside the oblique hole does not contact the upper top surface of the baffle ring, leaving a distance of 3mm to 5mm. This structure can realize the change in the opening of the oblique hole caused by the advancement and retreat of the linear motor, so that tablets or capsules can fall down smoothly without being stuck. At the same time, the design of the oblique mouth can also allow capsules to fall out one by one.
[0011] The described mechanism comprises a combination of a miniature push-pull electromagnet, an electromagnet medicine-pushing connector, and a height-limited pre-push medicine trough. The height-limited pre-push medicine trough has a reserved space of only the height of one tablet of most tablets. When a tablet falls into the height-limited pre-push medicine trough, the second tablet is above the first tablet, and most of its volume is still in the medicine outlet. The upper front end portion of the push rod of the electromagnet medicine-pushing connector is arc-shaped. When the miniature push-pull electromagnet loses power and the push rod of the electromagnet medicine-pushing connector is pushed out, only one tablet falls, and the other tablets are completely pushed back into the medicine outlet.
[0012] The beneficial effects of the present invention are mainly manifested in: effectively solving the problems of opening and closing bottles of bottled tablets, quickly dispensing medicines, storing medicines at a fixed location, and controlling the amount of medicines dispensed. The invention has made significant innovations in solving the problem of dispensing medicines from bottled tablets. It is equipped with a timing function to remind the elderly to take medicines on time, and the actions of "unscrewing" and "screwing back" simulated by human hands are simple and efficient. The invention has the characteristics of small size, low production cost, easy use, high working efficiency, good stability, etc. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] Reference Figures 1 to 10A flip-type medicine dispensing mechanism suitable for bottled tablets includes a box 1, a medicine box 2, a photoelectric switch 3, a chain-driven medicine storage mechanism 4, a servo motor 401, a sprocket A 402, a chain 403, a straight damping shaft 404, a tray 405, a shaking table fixture 406, a medicine bottle 407, a driven shaft 408, a bearing 409, a sprocket B 410, a flip-type gradient hole medicine dispensing mechanism 5, a base 501, a multifunctional bracket A 502, a steering gear A 503, a steering wheel A 504, a steering wheel connector 505, a linear motor 506, a linear motor module connector 507, a gradient hole medicine dispensing mechanism 508, an oblique mouth medicine dispensing cover 50801, a medicine dispensing gradient hole housing 50802, a gradient hole turntable 50803, and a steering wheel B. 50804, long connecting plate 50805, short connecting plate 50806, miniature push-pull electromagnet 50807, electromagnet drug push connector 50808, height-limited pre-drug slot 50809, servo B 50810, L-shaped connecting bracket A 50811, multi-function bracket B 50812, gradient port 50813, stepper motor bottle cap screwing module 6, guide shaft 601, stepper motor 602, lead screw 603, lead screw nut 604, connecting plate 605, bidirectional bottle cap screwing mechanism 606, bilateral clamp with rack (top) 60601, bilateral clamp with rack (bottom) 60602, gear 60603, fixed crossbeam plate 60604, bottle cap screwing housing 60605, steering wheel C 60606, servo C 60607, L-shaped bracket B 60608, multi-function bracket C 60609.
[0026] See also Figure 4 In the embodiment of the present invention, the chain-driven medicine storage mechanism 4 includes a servo motor 401, a sprocket A 402, a chain 403, a straight damping shaft 404, a tray 405, a shaking table clamp 406, a medicine bottle 407, a driven shaft 408, a bearing 409 and a sprocket B 410. First, place the medicine bottle on tray 405 and clamp it with the retractable shaker clamp 406. Tray 405 is connected to chain 403 via a straight damping shaft 1203. Chain 403 engages sprocket A 402 and sprocket B 410. Servo motor 401 is mounted on housing 1. The motor shaft engages sprocket B 410 via a keyed connection. Sprocket A 402 engages driven shaft 408 via a keyed connection. The servo motor 401 is controlled to rotate the sprocket, which in turn drives the chain, which in turn drives tray 1202. The servo motor's rotation angle is controlled to sequentially bring tray 405 and medicine bottle 407 to two designated positions: below the bidirectional capping mechanism 606 of the stepper motor capping module 601 and below the oblique dispensing cap 50802 of the gradient-hole dispensing mechanism 508 of the flip-type gradient-hole dispensing mechanism 501. Wait for further operation.
[0027] See also Figures 8 and 9The stepper motor bottle cap tightening module 6 in this embodiment of the present invention can perform functions such as unscrewing, re-screwing, and retracting a bottle cap. This stepper motor bottle cap tightening module 6 includes a guide shaft 601, a stepper motor 602, a screw 603, a screw nut 604, a connecting plate 605, a bidirectional bottle cap tightening mechanism 606, a double-sided clamp (upper) with a rack 60601, a double-sided clamp (lower) with a rack 60602, a gear 60603, a fixed crossbeam 60604, a bottle cap tightening housing 60605, a steering wheel C 60606, a steering gear C 60607, an L-shaped bracket B 60608, and a multifunctional bracket C 60609. Due to its complex structure, it is described in two separate sections: one describing the general structure and operation of the stepper motor bottle cap tightening module 6, and the other describing the detailed structure and operation of the key bidirectional bottle cap tightening mechanism 606.
[0028] See also Figure 8 In the overall structure of module 6, the stepper motor 602 and the guide shaft 601 are fixed on the box body 1. The output shaft of the stepper motor is a screw rod 603. The screw rod 603 is equipped with a screw nut 604. The screw nut 604 is equipped with a connecting plate 605. The connecting plate is connected to the L-shaped bracket B 60608 in the two-way bottle cap screwing mechanism 606. The overall mechanism operates as follows: to remove the bottle cap, when the medicine bottle is transferred by the chain-driven medicine storage mechanism 4 to the bottom of the bidirectional capping mechanism 606 of the stepper motor capping module 601, the stepper motor capping module 6 begins to move. The stepper motor rotates, the output screw rotates, and its upper screw nut moves downward until the fixed crossbar 60604 of the bidirectional capping mechanism 606 abuts the bottle cap and the strain gauge (very thin) on the fixed crossbar 60604 is abutted. When the stepper motor outputs a signal, the bidirectional capping mechanism 606 stops, and the bidirectional capping mechanism 606 performs the cap removal process. The stepper motor slowly reverses during the cap removal process (retracting the cap). After the process is complete, the stepper motor quickly reverses, driving the bidirectional capping mechanism 606 to reset. To recap, all actions are the same, except that the stepper motor slowly rotates forward during the cap recapping process (retracting the cap).
[0029] See also Figure 9, and then describe in detail the structural composition of the key mechanism, the two-way bottle cap screwing mechanism 606, wherein the bilateral clamp with a rack (upper) 60601 and the bilateral clamp with a rack (lower) 60602 are dynamically connected to the bottle cap screwing shell 60605 through the slide groove, and then the gear 60603 is engaged with the rack and embedded in the bottle cap screwing shell 60605, and the servo C60607 is installed on the multi-function bracket C60609 and the L-shaped bracket B 60608, and then the servo C 60607 passes through the bottle cap screwing shell 60605 and is connected to the gear 60603 by screws through the steering wheel C 60606, and finally the fixed crossbeam plate 60604 is installed on the corresponding mounting groove of the bottle cap screwing shell 60605 and fastened with screws and nuts through the mounting holes; as shown in FIG. Figure 3 The illustrated rack-mounted double-sided clamp (upper) 60601 and rack-mounted double-sided clamp (lower) 60602 have one L-shaped (concave) and one 7-shaped (flat) clamping edge in the same direction. A slight gap exists between the two clamping edges to prevent collision and wear during their opposing movements. In this embodiment, the servo 60607 and the chute of the two-way cap-tightening mechanism face downward, connecting to the other mechanisms. This mechanism primarily realizes the functions of unscrewing and re-screwing the bottle cap. When the entire bidirectional bottle cap-twisting mechanism 606 moves downward and its fixed crossbeam 60604 abuts against the top of the bottle cap, the mechanism begins to operate. The servo C 60607 rotates counterclockwise, driving the gear 60603 to rotate. At this time, the bottle cap-twisting housing 60605 remains stationary. The gears drive the bilateral clamp (upper) 60601 with a rack and the bilateral clamp (lower) 60602 with a rack to move in opposite directions. The pair of concave clamping edges of the rack clamp clamp the medicine bottle cap. At this time, the servo C 60607 continues to rotate counterclockwise, starting to drive the bottle cap-twisting housing 60605 to rotate. At the same time, the stepping motor 602 and the screw rod 603 outside the bidirectional bottle cap-twisting mechanism 606 slowly rotate in the opposite direction, driving the bidirectional bottle cap-twisting mechanism 606 to slowly move upward, gradually unscrewing and pulling up the bottle cap. When the medicine is taken out, the medicine bottle is again transferred to the bottom of the two-way bottle cap screwing mechanism 606 by the chain drive. The entire two-way bottle cap screwing mechanism 606 moves downward again, and the bottle cap contacts the bottle mouth. The pressure sensor detects a signal, and the servo C 60607 rotates clockwise. At this time, the other pair of flat clamping edges of the two-way clamp with rack (upper) 60601 and the two-way clamp with rack (lower) 60602 clamp the medicine bottle cap tightly, screwing the bottle cap back.
[0030] See also Figures 5 to 7 In the embodiment of the present invention, the flip-type gradual hole medicine dispensing mechanism 5 can theoretically complete the function of dropping most of the bottled medicines one by one and the function of flipping and reversing to the original position. Figures 5 and 6This mechanism includes a base 501, a multifunctional bracket A 502, a steering gear A 503, a steering wheel A 504, a steering wheel connector 505, a linear motor 506, a linear motor module connector 507, a gradient-hole drug dispensing mechanism 508, an oblique-mouth drug dispensing cover 50801, a drug dispensing gradient-hole housing 50802, a gradient-hole turntable 50803, a steering gear B 50804, a long connecting plate 50805, a miniature push-pull electromagnet 50807, an electromagnet drug-pushing connector 50808, a height-limited pre-drug-pushing slot 50809, a steering gear B 50810, an L-shaped connecting bracket A 50811, a multifunctional bracket B 50812, and a gradient-hole 50813. Due to its complex structure, it is described in two separate parts: one focusing on the overall structure and motion of the flip-type gradient-hole drug dispensing mechanism 5, and the other on the detailed structure and motion of the key mechanism, the gradient-hole drug dispensing mechanism 508.
[0031] See also Figure 5 In terms of the overall structure of the flip-type gradient hole medicine dispensing mechanism 5, the entire mechanism is connected and fixed to the box via a multifunctional bracket A502. The servo A503 is connected to the multifunctional bracket A502, and the steering wheel A504 is installed on the servo A503. The linear motor is installed in the base and connected to the steering wheel A504 via the base's steering wheel connector 505. The linear motor module connector 507 is installed on the top of the linear motor, and the linear motor module connector 507 is connected to the gradient hole medicine dispensing mechanism 508. The overall mechanism moves as follows: when the uncapped medicine bottle is transported by the chain drive medicine storage mechanism 4 to the bottom of the oblique medicine dispensing cover 50802 of the gradient hole medicine dispensing mechanism 508 of the flip-type gradient hole medicine dispensing mechanism 501, the flip-type gradient hole medicine dispensing mechanism 5 begins to move. The linear motor shortens and drives the gradient hole medicine dispensing mechanism 508 downward until the oblique medicine dispensing cover 508501 of the gradient hole medicine dispensing mechanism 508 fits the bottle mouth. The servo steering wheel A504 is installed on the servo A503. 504 rotates 180°. Since the tray 405 and the chain 403 are connected by a straight damping shaft 404, the oblique mouth medicine dispensing cover 50801 drives the tray 4 with the medicine bottle model 407 to rotate 180°. The gradient hole medicine dispensing mechanism 508 begins to perform the medicine dispensing action. After the photoelectric switch 3 detects the signal count, the gradient hole medicine dispensing mechanism 508 is closed after the specified target number of drops is dropped. The medicine box 2 below temporarily stores the medicine. The drawer outside the medicine box 2 is pulled to complete the medicine dispensing. After the medicine is taken, the steering wheel A504 of the servo rotates 180° in the opposite direction, causing the flip-type gradient hole medicine dispensing mechanism 5 to flip back, and the linear motor moves upward to the initial position. This completes a complete action process of the flip-type gradient hole medicine dispensing mechanism 5.
[0032] See also Figures 6 and 7The structure of the key mechanism, the gradual-hole medicine dispensing mechanism 508, is described in detail. The oblique-mouth medicine dispensing cover 50801 is connected to the medicine dispensing gradual-hole housing 50802 with screws and nuts through the holes on the circular surface. The servo B 50810 is connected to the gradual-hole rotating disk 50803 via its upper steering wheel B 50804. The center portion of one circular surface of the gradual-hole rotating disk 50803 is fixed to the steering wheel B 50804 of the servo B 50810, so that the gradual-hole rotating disk 50803 rotates with the steering wheel. The other circular surface is close to the inner circular surface of the medicine dispensing gradual-hole housing 50802 but does not hinder the rotation of the gradual-hole rotating disk 50803 (the distance is about 0.5 mm). The multifunctional bracket B 50812 on which the servo B 50810 is mounted is connected to the medicine dispensing gradual-hole housing 50802 by a short connecting plate 50806 and a long connecting plate 50805. The corresponding parts are fixed with bolts, and the height-limiting pre-push medicine trough plate 50809 is installed on the side of the medicine outlet gradient housing 50802 closer to the bevel by means of screws and nuts, with its arc-shaped groove part aligned with the medicine outlet hole. The miniature push-pull electromagnet 50807 is installed on the long connecting plate 50805, and the hole end of the electromagnet medicine pushing connector 50808 is connected to the push rod of the miniature push-pull electromagnet 50807, and its cross-section is a double-arc-shaped part that cooperates with the arc-shaped groove part of the height-limiting pre-push medicine trough plate 50809. The L-shaped connecting bracket A 50811 is connected to the multi-functional bracket B 50812, and is connected to the line motor module connector 507. When the gradient hole medicine dispensing mechanism 508 is brought downward to the medicine bottle, the oblique mouth medicine dispensing cover 50801 of the gradient hole medicine dispensing mechanism 508 is attached to the mouth of the medicine bottle and is completely turned over to the medicine bottle and the gradient hole medicine dispensing mechanism 508 is downward, the mechanism starts to operate. First, the micro push-pull electromagnet 50807 is energized, and its push rod and electromagnet medicine pushing connector 50808 are retracted, followed by the push rod servo B. 50807 drives the gradual mouth turntable 50803 at a slower speed, so that the relative size of the gap between the gradual mouth turntable 50803 and the oblique mouth medicine outlet cover 50801 becomes larger, causing the medicine to fall out of the arc groove of the height-limited pre-pushing medicine slot plate 50809. Then, since the height of the reserved space in the arc groove is the height of most tablets, the micro push-pull electromagnet 50807 loses power at this time, and the electromagnet medicine pushing connector 50808 is pushed by the micro push-pull electromagnet 50807 to reset, so that only one tablet falls out and the excess medicine is pushed back; the photoelectric switch 3 is fixed below the medicine outlet (such as Figure 2 As shown, it is fixed on the box body. When the falling tablet is detected by the photoelectric sensor 3, the servo B50807 rotates in the opposite direction quickly, causing the relative size of the opening of the gradient-mouth turntable 50803 and the oblique-mouth medicine dispensing cover 50801 to quickly decrease, causing the mechanism to temporarily stop dispensing medicine. At this time, a pill falls out and falls into the medicine box 2, completing one pill dropping action. The number of completed pill dropping actions is the target number of pills dropped.
[0033] The overall working principle of the present invention is as follows: first, the medicine bottle 407 is placed on the tray 405 and clamped by the shaking table clamp 406, and the servo motor 401 drives the chain transmission to bring the tray 405 and the medicine bottle 407 to the bottom of the two-way bottle cap screwing mechanism 606 of the stepper motor bottle cap screwing module 601; the stepper motor 602 rotates forward, so that the transmission of the screw rod and the screw rod nut drives the two-way bottle cap screwing mechanism 606 to move downward to reach the specified position (above the bottle cap of the medicine bottle), the servo C 60607 drives the two-way bottle cap screwing mechanism 606 to open the bottle cap and carry the bottle cap, and the stepper motor 602 moves upward to reset; the servo motor 401 drives the chain transmission to bring the tray 405 and the medicine bottle 407 to the bottom of the oblique mouth medicine dispensing cover 50801 of the gradient hole medicine dispensing mechanism 508 of the flip-type gradient hole medicine dispensing mechanism 501.
[0034] The linear motor 506 moves downward until the oblique mouth medicine dispensing cover 50801 of the gradient hole medicine dispensing mechanism 508 fits the mouth of the medicine bottle, and the servo steering wheel A 504 rotates 180 degrees. Since the tray 405 and the chain 403 are connected by a straight damping shaft 404, the oblique mouth medicine dispensing cover 50801 drives the tray 1202 with the medicine bottle model 407 to all parts between the chain 403 to rotate 180 degrees; the gradient hole medicine dispensing mechanism 508 starts to perform the medicine dispensing action. The servo B 50810 drives the gradient hole medicine dispensing mechanism 507 to move and the micro push-pull electromagnet 50807 to be energized and de-energized, and the medicine pellets fall out. After the photoelectric switch 13 detects the signal and counts, the gradient hole medicine dispensing mechanism 508 is closed after the specified target number of drops is reached, and the medicine box 2 below temporarily stores the medicine. The drawer outside the medicine box 2 is pulled to complete the medicine dispensing. After the medicine is taken out, the servo steering wheel A 504 rotates 180° in the opposite direction, causing the flip-type gradient-hole dispensing mechanism 5 to flip back, and the linear motor 506 moves upward to its initial position. The medicine bottle 407 is again transferred by the chain drive to the bottom of the two-way bottle capping mechanism 606. The stepper motor 602 rotates forward, causing the screw and screw nut to drive the two-way bottle capping mechanism 606 downward until it contacts the bottle mouth. The servo C 60607 in the two-way bottle capping mechanism 606 rotates in the opposite direction to tighten the bottle cap. The servo C 60607 is slightly rotated to loosen the two-way bottle capping mechanism 606, and the stepper motor rotates in the opposite direction, returning the two-way bottle capping mechanism 606 to its initial position. This completes one process.
[0035] The embodiments of the present invention are not exclusive, and the above embodiments are intended to be illustrative. The present invention can change the parameters and movement steps through program control to achieve different movement combinations that meet different needs.
