Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical processing, and particularly relates to a tablet grooving device for the production of avanafil. Background Art

[0002] Avanafil is a highly selective oral phosphodiesterase 5 inhibitor. Compared with other phosphodiesterase 5 inhibitors for the treatment of erectile dysfunction, avanafil has the characteristics of rapid onset, short duration of action, and fewer adverse reactions, and has good clinical efficacy and safety. A tablet grooving device is a device used to manufacture tablets, and its function is to open grooves or score lines on the tablets. These grooves or score lines help to divide the tablets into equal doses and can help patients accurately divide and take the medicine.

[0003] In the production process of drugs such as avanafil, tablet grooving is an important processing link, and its precision and efficiency directly affect the drug quality and production efficiency. Existing tablet grooving devices have many deficiencies in actual applications: on the one hand, during the tablet conveying process, stacking or tipping of tablets is likely to occur, resulting in individual tablets being unable to stably enter the processing station, which not only affects the production rhythm but also may cause material loss and pollution risks due to manual intervention; on the other hand, if the drug chips generated during the grooving process cannot be cleaned in time, they are likely to accumulate in the processing area, affecting the grooving precision and equipment hygiene. Traditional chip removal structures often rely on single gravity or simple air flow, with low chip removal efficiency and inconvenient cleaning, and it is difficult to meet the hygiene standards of drug production. In addition, the detection of the grooving quality of existing devices for tablets mostly adopts contact or manual sampling inspection methods, with low detection precision and slow speed, and it is impossible to reject unqualified products in real time, resulting in defective products flowing into subsequent processes and affecting the product qualification rate. Summary of the Invention

The pressing tongue and the blocking member form a limiting space to prevent the tablet from tipping over during the pushing process; a correction mechanism is provided at a position on the input machine close to the discharge port. The correction mechanism is used to prevent the tablets from stacking during the conveying process. The correction mechanism consists of a correction frame, a buffer rod, a pressing plate, and a buffer spring.

One end of the pressing plate facing the direction where the tablets are sent is in an upturned structure. Buffer springs are sleeved on the buffer rods. Only a single horizontally lying tablet can pass through the conveying channel below the pressing plate.

[0007] Optionally, a corresponding material receiving port is provided at the position where the slotted slide is connected to the discharge port, and a photoelectric sensor is vertically provided on the slotted slide inside the material receiving port, and the photoelectric sensor is used to detect whether there are tablets entering, and receiving ends are respectively provided at the positions corresponding to the slotting position and the detection position on the side wall of the slotted slide facing the material control and shifting rack, and a chip removal guide groove is longitudinally provided on the side of the slotted slide at the detection position close to the slotted frame, and the chip removal guide groove is a structure inclined from the slotted slide to the lower side of the slotted frame, and the end of the chip removal guide groove is above the medicine chip collection rack, and a medicine chip collection tray is provided at the upper end of the medicine chip collection rack for collecting medicine chips discharged from the chip removal guide groove, and the medicine chip collection tray is stuck between the upper end of the medicine chip collection rack and the bottom of the slotted slide in a drawer-drawn manner from one side; receiving ends are respectively provided on the side wall of the slotted slide facing the material control and shifting rack at the corresponding detection position and the slotting position.

[0008] Optionally, the two-axis displacement mechanism is composed of a transverse frame, a transverse motor, a screw rod, a longitudinal cylinder, a material plate, a fork, a photoelectric limit switch and a transmitting end. The transverse frame is parallel to the slotted slide, and the transverse motor is fixedly installed at one end of the transverse frame. The screw rod is rotatably installed in the transverse frame. The transverse motor drives the screw rod to rotate, and the longitudinal cylinder is longitudinally slidably installed on the transverse frame and is screwed vertically and rotatably connected to the screw rod. The rotation of the screw rod drives the longitudinal cylinder to move laterally on the transverse frame. The end of the piston rod of the longitudinal cylinder is fixedly connected to the Y-shaped material plate toward the slotted slide, and forks for accommodating a single tablet are respectively provided at both ends of the wide side of the material plate. A photoelectric limit switch is fixedly installed downward on the material plate at the root of the fork near one end of the output machine, and the transmitting end of the photoelectric limit switch faces the slotted slide, and the transmitting end corresponds to the receiving end on the side wall of the slotted slide. The photoelectric sensor is interlocked with the transverse motor and the longitudinal cylinder. In the initial state, the The fork near the input machine is at the receiving port to receive the tablets, and the other fork is at the waiting position. After the photoelectric sensor sends a tablet entry signal, the transverse motor works to drive the material plate to move to one side of the output machine. After the transmitting end is aligned with the receiving end of the slotting position, the transverse motor stops, and the slotting mechanism works to slot the tablets at the slotting position. After the slotting mechanism finishes working, the transverse motor continues to work, and the material plate continues to move. After the transmitting end is aligned with the receiving end of the detection, the transverse motor stops, and the detection mechanism works. If the tablets are qualified, the piston rod of the longitudinal cylinder contracts, driving the material plate to withdraw from the slotting slide, and the transverse motor resets to enter a cycle. The tablets at the detection position are waiting for the end of the material plate to move horizontally for the next action and are pushed into the output machine for output. If the tablets are unqualified, the steering mechanism and the unloading mechanism work to send the tablets at the detection position into the waste rejection pipe and discharge them into the defective product tray below.

[0009] Optionally, the grooving mechanism is composed of a grooving cylinder, a hanging seat, a grooving saw blade, a grooving motor, an accompanying blower, a chip blowing air pipe, and a baffle. The end of the piston rod of the grooving cylinder faces the grooving slideway and is fixedly connected to the hanging seat. The grooving saw blade is rotatably installed at the lower end of the hanging seat. An arc-shaped baffle is arranged outside the upper end of the grooving saw blade. A grooving motor for driving its rotation is fixedly installed on the hanging seat on one side of the grooving saw blade. An accompanying blower is arranged on the hanging seat on the other side. The accompanying blower and the grooving saw blade are coaxial and fixedly connected to the rotating shaft of the grooving motor. The air outlet end of the accompanying blower is fixedly connected to the chip blowing air pipe. The chip blowing air pipe is installed at one end of the baffle far away from the grooving rack. The outlet of the chip blowing air pipe is obliquely downward towards the chip discharging guide groove. The grooving saw blade moves along the chip discharging guide groove. The grooving cylinder and the grooving motor are synchronously interlocked. When the grooving cylinder moves horizontally to push the hanging seat part towards the grooving slideway, the grooving saw blade rotates to groove the upper end of the tablet at the grooving position. The chips cut by the rotation of the grooving saw blade are shot towards the chip discharging guide groove. The airflow generated by the synchronous rotation of the accompanying blower is ejected through the chip blowing air pipe to assist the chips to be smoothly discharged from the chip discharging guide groove into the chip collection tray.

[0010] Optionally, the detection mechanism includes a detection frame and a CCD camera. The CCD camera is arranged at the upper end of the detection frame. The CCD camera faces the detection position below. The CCD camera collects images and sends them to the controller for processing to judge the integrity and grooving condition of the tablets. Both broken tablets and incomplete grooving are judged as unqualified.

[0011] Optionally, the steering mechanism is composed of a steering cylinder, a rack, a steering shaft, a gear, and a detection caddy. The steering cylinder is horizontally installed on the steering frame. The end of the piston rod of the steering cylinder is fixedly connected to a horizontal rack.

The detection caddy is provided with a card slot for accommodating a single tablet. The bottom of the card slot is flush with the bottom of the cavity of the grooving slideway. A gear is fixedly arranged at the position of the steering shaft corresponding to the rack. The gear meshes with the rack. When the tablet is qualified, the card slot of the detection caddy is in the same direction as the channels of the grooving slideway and the output machine. When the tablet is unqualified, the steering cylinder works, drives the rack to move, and the steering shaft rotates 90 degrees. The card slot of the detection caddy faces the waste removal pipe.

[0012] Optionally, the discharging mechanism is composed of a compressed air pipe, a control ball valve, and a discharging pipe. One end of the compressed air pipe is connected to an external compressed air pump, and the other end of the compressed air pipe is fixedly connected to the control ball valve. The control ball valve is fixedly installed on the bogie below the steering shaft, and the valve core rotating shaft of the control ball valve is fixedly connected to the lower end of the steering shaft. The other end of the control ball valve is connected to the discharging pipe. The discharging pipe penetrates into the detection position of the slotted slide from the side frame at the output end of the machine. The end of the discharging pipe faces the inlet of the waste rejection pipe. When the slot of the detection bracket faces the waste rejection pipe, that is, the control ball valve is also opened synchronously, and compressed air is ejected from the discharging pipe to blow the tablets and debris in the detection bracket into the waste rejection pipe synchronously. The steering cylinder resets, the detection bracket resets, and the control ball valve closes.

[0013] The present invention provides a tablet slotting device for the production of avanafil, which has the following beneficial effects:

[0014] Through the collaborative design and linkage control of each mechanism, the present invention realizes the high efficiency, precision, and automation of the avanafil tablet slotting process, significantly improving the production quality and stability. The feeding mechanism and the rectifying mechanism of the input machine ensure that the tablets enter the slotted slide in an orderly manner in a single horizontal lying posture through the elastic guidance of the tongue pressing limit space and the pressing plate, avoiding stacking and side turning during the conveying process, providing a stable material input basis for subsequent processes, and reducing manual intervention and material loss. The slotted slide, in cooperation with the photoelectric sensors, receiving end, and transmitting end of the two-axis displacement mechanism, realizes the precise positioning and orderly transfer of the tablets at the waiting position, slotting position, and detection position, making the actions of each working station connect smoothly and significantly improving the controllability of the production beat.

[0015] In the slotting mechanism, the coaxial design of the slotting saw blade and the accompanying blower blows the drug debris into the drug debris collection tray along the inclined chip discharge guide groove through the chip blowing air pipe while slotting. This structure not only reduces the influence of drug debris residue on the slotting accuracy, but also facilitates subsequent cleaning through the drawer-type tray design, ensuring the cleanliness inside the device and meeting the hygiene standards of drug production. The detection mechanism uses non-contact image detection with a CCD camera, which can quickly and accurately judge the integrity and slotting quality of the tablets. Combined with the pneumatic interlock control of the steering mechanism and the discharging mechanism, it realizes the automatic reverse rejection of unqualified products, avoiding defective products from flowing into the next process and effectively improving the product qualification rate.

[0016] In addition, the vertical cylinder structure design of the suspension seat in the second embodiment can flexibly control the slotting depth by adjusting the cylinder stroke, enabling the device to adapt to the slotting requirements of different specifications of tablets, and significantly improving the versatility and processing adaptability of the equipment. Overall, through the deep integration of mechanical structure, sensing detection, and pneumatic control, the device constructs a full-process automation system from tablet input, slotting processing, quality inspection to rejection of defective products. While improving production efficiency, it ensures high precision and high reliability in pharmaceutical production, with significant technological progress and practical value.

Both broken tablets and incomplete grooving are judged as unqualified.

[0052] Among them, the steering mechanism is composed of a steering cylinder 1201, a rack 1202, a steering shaft 1203, a gear 1204, and a detection bracket 1205. The steering cylinder 1201 is horizontally installed on the bogie 12. The end of the piston rod of the steering cylinder 1201 is fixedly connected to a horizontal rack 1202. The rack 1202 is slidably clamped on the bogie 12. The outer side of the tooth groove end of the rack 1202 is a vertical steering shaft 1203. The upper end of the steering shaft 1203 vertically rotates through the detection position and is fixedly connected to a detection bracket 1205. The detection bracket 1205 is provided with a card slot for accommodating a single tablet. The bottom of the card slot is flush with the bottom of the cavity of the slotted slideway 4. A gear 1204 is fixedly provided at a position corresponding to the rack 1202 on the steering shaft 1203. The gear 1204 meshes with the rack 1202. When the tablet is qualified, the card slot of the detection bracket 1205 is in the same direction as the slotted slideway 4 and the channel of the output machine 5. When the tablet is unqualified, the steering cylinder 1201 works, driving the rack 1202 to move, and the steering shaft 1203 rotates 90 degrees. The card slot of the detection bracket 1205 faces the waste removal pipe 9.

[0053] Among them, the unloading mechanism is composed of a compressed air pipe 13, a control ball valve 1301, and an unloading pipe 1302. One end of the compressed air pipe 13 is communicated with an external compressed air pump. The other end of the compressed air pipe 13 is fixedly connected to the control ball valve 1301. The control ball valve 1301 is fixedly installed on the bogie 12 below the steering shaft 1203. The valve core rotating shaft of the control ball valve 1301 is fixedly connected to the lower end of the steering shaft 1203. The other end of the control ball valve 1301 is connected to the unloading pipe 1302. The unloading pipe 1302 penetrates into the detection position of the slotted slideway 4 from the side frame at the output machine 5 end. The end of the unloading pipe 1302 faces the inlet of the waste removal pipe 9. When the card slot of the detection bracket 1205 faces the waste removal pipe 9, that is, the control ball valve 1301 is also opened synchronously. Compressed air is ejected from the unloading pipe 1302 to blow the tablet and debris in the detection bracket 1205 into the waste removal pipe 9 synchronously. The steering cylinder 1201 resets, the detection bracket 1205 resets, and the control ball valve 1301 closes.

[0054] Embodiment 2, on the basis of Embodiment 1, the suspension seat 802 can also be a vertically arranged cylinder structure. The end of the cylinder is connected to the slotted saw blade 803, the slotted motor 804, the accompanying blower 805, the chip blowing air pipe 8051, and the baffle 806 through a connecting seat, so that the slotted depth can be controlled and adjusted.

[0055] The following is a further explanation and description of the above structures for those skilled in the art to better understand the technical solutions:

[0056] In the tablet grooving device for the production of avanafil, the feeding mechanism at the end of the input machine 3 and the correction mechanism cooperate to ensure the orderly transportation of tablets. In the feeding mechanism, the feeding cylinder 302 drives the blocking member 303 to reciprocate through the piston rod. When the piston rod contracts, the end of the blocking member 303 is flush with the inner wall of the conveying channel of the input machine 3, which can block the forward movement of subsequent tablets. When the piston rod extends, the pressing tongue 3031 at the end of the blocking member 303 forms a limiting space with the inner wall of the conveying channel, which can prevent the pushed tablets from tipping over when passing through the discharge port 301, ensuring that a single tablet enters the grooving slideway 4 stably. The correction frame 304 of the correction mechanism straddles the upper part of the conveying channel. The pressing plate 3042 at the lower end of the buffer rod 3041 is pressed down under the action of the buffer spring 3043. The upturned structure at its front end can guide the stacked tablets, and cooperate with the channel below that only allows a single horizontally lying tablet to pass through, effectively avoiding the stacking of tablets during transportation and providing an orderly tablet input for subsequent processes.

[0057] As the core channel for tablet processing, the photoelectric sensor 401 at the material receiving port 403 of the grooving slideway 4 detects in real time whether the tablets enter, providing a trigger signal for the action of the two-axis displacement mechanism. On the side wall of the material control and displacement frame 6, the receiving end 402 set corresponding to the grooving position and the detection position cooperates with the transmitting end 6061 of the two-axis displacement mechanism to achieve precise positioning of the position of the material plate 605. The chip removal guide groove 404 at the detection position is of an inclined structure. The chips cut by the grooving saw blade 803 slide along the chip removal guide groove 404 to the chip collection tray 1001 under the action of the air flow generated by the associated blower 805 and its own gravity. The tray is designed in a drawer type for easy cleaning, keeping the inside of the device clean and avoiding chip accumulation from affecting production.

[0058] The two-axis displacement mechanism on the material control and displacement frame 6 undertakes the task of transferring tablets between different workstations. The transverse movement motor 602 drives the lead screw 603 to rotate, driving the longitudinal movement cylinder 604 to move horizontally along the transverse movement frame 601. The fork openings 6051 at both ends of the material plate 605 can respectively accommodate a single tablet. In the initial state, the fork opening 6051 close to the input machine 3 picks up the tablet at the material receiving port 403, and the other fork opening 6051 is in the waiting position; when the photoelectric sensor 401 detects the entry of the tablet, the transverse movement motor 602 works, and the material plate 605 moves. It stops when the transmitting end 6061 is aligned with the receiving end 402 at the grooving position, so that the tablet is accurately at the grooving position to receive the grooving operation; after grooving, it continues to move to the detection position. The qualified tablets are pushed into the output machine 5 by the subsequent material plate 605, and the unqualified ones trigger the steering and unloading mechanism. Through precise displacement control, this mechanism realizes the orderly stay and transfer of tablets at the waiting, grooving, and detection workstations, ensuring the smooth connection of each process.

[0059] The grooving mechanism is installed on the grooving machine frame 8. The grooving cylinder 801 drives the suspension seat 802 to approach or move away from the grooving slideway 4. The grooving motor 804 drives the grooving saw blade 803 to rotate at a high speed, and grooves the upper end of the tablet at the grooving position. The arc-shaped baffle 806 can limit the range of chip splashing, facilitating collection. The accompanying blower 805 rotates coaxially with the grooving motor 804, and the generated air flow is sprayed onto the chip discharge guide groove 404 through the chip blowing air pipe 8051, assisting in quickly discharging the chips generated during the grooving process. With the inclined design of the chip discharge guide groove 404, the chip collection efficiency is improved, the influence of chips on the grooving accuracy is reduced, and the grooving quality is guaranteed.

[0060] The detection mechanism consists of a detection frame 901 and a CCD camera 902. The CCD camera 902 is installed at the upper end of the detection frame 901, facing the detection position to collect tablet images in real time. The image signals are transmitted to the controller 2 for processing and analysis to determine whether the tablet is complete and whether the grooving meets the requirements. The damaged or incompletely grooved tablets are determined as unqualified products. This non-contact detection method features high detection accuracy and fast speed, ensuring that unqualified products are promptly identified and prevented from flowing into the next process.

[0061] For the detected unqualified products, the steering mechanism and the discharging mechanism are linked to achieve the rejection function. The steering cylinder 1201 drives the rack 1202 to move horizontally. Through the meshing transmission of the gear 1204 and the steering shaft 1203, the detection caddy 1205 rotates by ninety degrees, and its card slot changes from being in the same direction as the grooving slideway 4 to facing the waste rejection pipe 9. At the same time, the control ball valve 1301 at the lower end of the steering shaft 1203 rotates synchronously with the steering shaft 1203. When the card slot aligns with the waste rejection pipe 9, the control ball valve 1301 opens, and the compressed air in the compressed air pipe 13 is sprayed out through the discharge pipe 1302, blowing the unqualified tablets and chips in the detection caddy 1205 into the waste rejection pipe 9 and falling into the defective product tray 11 below. This mechanism realizes the automatic commutation and rejection of unqualified products through the interlocking control of mechanical and pneumatic components, ensuring that only qualified tablets are output by the output machine 5 and improving the consistency of product quality.

[0062] Working principle: During the operation of the tablet grooving device for avanafil production, the input machine 3 first pre-treats the ungrooved tablets. When the tablets in the conveying channel of the input machine 3 move forward, the correction mechanism near the discharge port 301 comes into play. The pressing plate 3042 on the correction frame 304 presses down with adjustable pressure through the cooperation of the buffer rod 3041 and the buffer spring 3043. The upturned structure at its front end guides the possibly stacked tablets, enabling the tablets to pass through the conveying channel in a single horizontal lying posture. When the tablets reach near the discharge port 301, the piston rod of the pushing cylinder 302 of the pushing mechanism extends, driving the blocking member 303 to move forward. The pressing tongue 3031 at the end forms a limiting space with the inner wall of the conveying channel, smoothly pushing a single tablet into the receiving port 403 of the grooving slideway 4, while one side of the blocking member 303 blocks the entry of the next tablet. When the piston rod retracts, the end of the blocking member 303 is flush with the inner wall of the channel, allowing the next tablet to enter below the pressing tongue 3031, ensuring that only a single tablet is pushed each time.

[0063] After the tablet enters the receiving port 403, the photoelectric sensor 401 in the grooving slideway 4 detects a signal, triggering the action of the two-axis displacement mechanism on the material control and displacement frame 6. The transverse movement motor 602 drives the lead screw 603 to rotate, driving the longitudinal movement cylinder 604 and the material plate 605 to move horizontally along the transverse movement frame 601. The fork openings 6051 at both ends of the material plate 605 are respectively used for receiving and transferring materials. In the initial state, the fork opening 6051 near the input machine 3 catches the tablet at the receiving port 403, and the other fork opening 6051 is in the waiting position; when the material plate 605 moves to align the transmitting end 6061 with the receiving end 402 of the grooving position, the transverse movement motor 602 stops, and at this time the tablet is in the grooving position. The grooving cylinder 801 of the grooving mechanism drives the suspension seat 802 to move towards the grooving slideway 4 (if the suspension seat 802 is a vertical cylinder structure, the grooving depth can be controlled by adjusting the cylinder stroke). The grooving motor 804 drives the grooving saw blade 803 to rotate at high speed, grooving the upper end of the tablet. The arc-shaped baffle 806 blocks the splashing of chips. The accompanying blower 805 rotates coaxially with the grooving motor 804, and the generated air flow is sprayed towards the chip discharge guide groove 404 through the chip blowing air pipe 8051, blowing the chips generated by grooving along the inclined chip discharge guide groove 404 into the chip collection tray 1001.

[0064] After the grooving is completed, the transverse movement motor 602 continues to work, and the material plate 605 moves to align with the receiving end 402 of the detection position at the transmitting end 6061. The CCD camera 902 of the detection mechanism collects images of the tablets at the detection position, and the signals are transmitted to the controller 2 for analyzing and judging the integrity of the tablets and the grooving quality. If the tablets are qualified, the piston rod of the longitudinal movement cylinder 604 contracts to drive the material plate 605 to withdraw from the grooving slideway 4, the transverse movement motor 602 resets, and when the subsequent material plate 605 moves, the qualified tablets at the detection position are pushed into the output machine 5; if the tablets are unqualified, the steering cylinder 1201 works, and through the meshing transmission of the rack 1202 and the gear 1204, the steering shaft 1203 rotates by ninety degrees, and the card slot of the detection card holder 1205 changes from the forward grooving slideway 4 to face the waste removal pipeline 9. At the same time, the control ball valve 1301 at the lower end of the steering shaft 1203 is synchronously opened, and the compressed gas in the compressed air pipe 13 is ejected through the discharge pipe 1302, blowing the unqualified tablets and debris into the waste removal pipeline 9 and falling into the lower defective product tray 11. After the steering cylinder 1201 resets, the detection card holder 1205 and the control ball valve 1301 return to the initial state, waiting for the next action. During the whole process, the two-axis displacement mechanism realizes the orderly transfer of the tablets at the waiting position, grooving position, and detection position through precise transverse and longitudinal movement control. Each mechanism ensures the automation and high efficiency of the tablet grooving, detection, rejection, and output processes through the interlocking cooperation of sensor detection, motor drive, and pneumatic control.
