Description

Technical Field

[0001] The present invention relates to the technical field of medicine sorting, and in particular to a medicine cold chain sterilization and sorting device. Background Art

[0002] Cold chain disinfection refers to the disinfection of tablets and their packaging, transportation vehicles, storage environment, etc. in order to control and reduce the contamination of pathogens (such as bacteria, viruses and other microorganisms) and ensure the safety of drugs during the cold chain logistics process. This process is of great significance for preventing drugs from being contaminated, ensuring drug safety, and complying with medical and health regulations. Tablets are a common drug dosage form. They are tablet preparations made by mixing drugs and excipients and then pressing them. Ozone disinfection is a way of cold chain disinfection. After the tablets are produced, the use of ozone for disinfection is a common sterilization method. Ozone decomposes into oxygen during the disinfection process and will not leave harmful residues in the tablets or the production environment. Therefore, it is called a pollution-free disinfectant.

[0003] When sterilizing existing tablets, in order to maintain the subsequent sorting and bottling work, multiple sterilization work will be carried out in batches according to categories. If the number of tablets in each batch is small, the sterilization resources of the equipment will be wasted and the sterilization efficiency will be reduced. A stable sorting device can help solve this problem. Therefore, a drug cold chain sterilization and sorting device is needed. Summary of the invention

The ozone will follow the air permeable net to uniformly disinfect the tablets of different sizes on the inclined plate. The tablets gradually enter the cylinder along the inclined plate, and then the motor is started. The gear 1 on the driving end driven by the motor rotates, and at the same time drives another gear 1 connected to the driving shaft and the connected pulley 1 to rotate. The pulley 1 is connected to the other pulley 1 connected to the rotating wheel through the belt drive and rotates synchronously. The rotating wheel drives the entire column frame to rotate and displace. The tablets in the stacked cylinder are subjected to slight vibrations under the influence of the rotation of the rotating wheel, changing the stacking state. The tablets at the bottom layer are arranged vertically and enter the arranging frame. When they move to the through slot of the cylinder, they fall into the sorting channel and roll along the slope in the sorting channel. The tablets that meet the specifications during rolling enter the sorting slot inside the sorting channel. The tablets that are larger than the sorting slot at this position continue to roll until they enter the corresponding sorting slot and fall into the guide frame along the discharge port. The metering valve on the guide frame controls the opening and closing of the output end to pour the tablets into the medicine bottles transported by the medicine bottle conveyor belt. During the unloading period, the medicine bottle conveyor belt stops conveying to cooperate with the unloading. After the unloading medicine bottle is transported to the end of the medicine bottle conveyor belt, it falls on the belt body. When the rear end gear roller driven by the rotating drive shaft rotates, the synchronous transmission The belt body is displaced, and the toothed roller at the front end connected to the rotating shaft is rotated. The rotating shaft drives the transmission shaft and the missing gear 1 in turn through the meshing bevel gear to rotate. The missing gear 1 indirectly meshes with the gear 2 connected to the feeding disk to rotate. After the medicine bottle on the belt body is stuck in the groove on the feeding disk, the rotating feeding disk drives the medicine bottle to be displaced through the groove and detaches from the top side of the belt body. The next vacant groove continues to receive the material. The medicine bottle passes through the bottom side of the bottle cap feeder and the bottle cap tightening device in turn to be packaged. A set of pulleys 2 driven by the rotating shaft using a cross belt will drive the missing gear 2 to rotate, indirectly meshing with the rack connected to the piston 1, causing the piston 1 to move downward, compressing the connected The spring squeezes the air in the piston cylinder, causing the air to squeeze from one air cavity into another air cavity, lifting the piston 2 in the other air cavity, and the piston 2 together with the abutment frame connected thereto rises, and the inclined surface structure on the bottom side of the abutment frame releases the abutment against the inclined surface of the abutment member, thereby causing the abutment member to move outward under the push of the compressed spring, releasing the abutment and fixation on the bottle cap inside the storage basket, so that the bottle cap falls on the medicine bottle, and after the medicine bottle subsequently moves to the bottom side of the bottle cap tightening device, the bottle cap tightening device connected to the piston 1 moves downward and rotates to tighten the bottle cap, completing the packaging, and the packaged medicine bottle is transported back to the belt body by the feeding tray, and the belt body transports the medicine bottle to the end, and falls into the feed port and is collected by the collection box. The excess low-temperature ozone gas for disinfection in the storage tank will also enter the gas channel connected to the transparent frame through the pipeline, and the medicine bottles in the collection box in the transparent frame will be disinfected again.

[0022] The present invention provides a drug cold chain sterilization and sorting device. It has the following beneficial effects:

[0023] 1. The present invention arranges the tablets into a vertical rolling posture so that the tablets can be transported inside the sorting channel 5 and the size is determined when the tablets roll through the sorting slot. The tablets that meet the size of the sorting slot will be sorted by falling from the entrance of the sorting slot, and the loading work is completed, thereby improving the work efficiency and the efficiency and accuracy of sorting.

[0024] 2. The present invention integrates the cold chain disinfection, sorting and bottling of tablets, and can uniformly disinfect tablets of different specifications, avoiding the need to sterilize tablets in batches due to specifications, thereby reducing tedious work and improving work efficiency.

[0025] 3.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0045] The embodiment of the present invention provides a drug cold chain sterilization and sorting device, comprising:

[0046] Please see attached Figure 1 , Attachment Figure 3 and attached Figure 4, a storage tank 1, a cylinder 2 is fixedly connected to the right side of the storage tank 1, an inclined plate loaded with an air-permeable net is arranged inside the storage tank 1, and low-temperature ozone for cold chain disinfection is poured into the air inlet on the bottom side of the storage tank 1, which is used to introduce the tablets into the cylinder 2, and the tablets are introduced into the sorting channel 5 for sorting through the collecting wheel rotating inside the cylinder 2, the top side of the sorting channel 5 is connected to the bottom side of the cylinder 2, and the bottom sides of multiple output ends of the sorting channel 5 are fixedly connected with a material guide frame 6, and a metering valve 7 for controlling the flow of materials is installed at the output end of the material guide frame 6, and a medicine bottle conveyor belt 8 for transporting empty medicine bottles is arranged on the bottom side of the metering valve 7, so that the tablets can be filled into the medicine bottles through the opening and closing of the metering valve 7, and the lengths of the multiple medicine bottle conveyor belts 8 are different to cooperate with the assembly lines at different positions for unloading, and the output ends of the multiple medicine bottle conveyor belts 8 are fixedly connected with anti-tilt rings 9;

[0047] Specifically, a feeding port is provided on the top side of the storage tank 1, and a sealing cover is provided to reduce the consumption and waste of ozone disinfection. The tablets loaded in the storage tank 1 are filled with ozone for cold chain disinfection through the air inlet on the bottom side of the storage tank 1. The ozone will uniformly disinfect the tablets of different sizes on the inclined plate along the breathable net. The unified disinfection of tablets of different specifications reduces the multi-batch disinfection process, thereby reducing the tedious work and improving the work efficiency. The tablets in the storage tank 1 also gradually enter the cylinder 2 along the inclined plate.

[0048] Please see attached Figure 5 -Attached Figure 7 The collecting wheel is composed of a rotating wheel 3 rotatably connected to the inside of the cylinder 2 and an alignment frame 4 arranged around the outer wall of the rotating wheel 3. A guiding inclined surface is arranged at the inner opening of the alignment frame 4. A through groove is arranged on the bottom side of the cylinder 2. The through groove is located on the side close to the rotating wheel 3 and the sorting channel 5. A rolling cavity is arranged inside the sorting channel 5. A sorting slot connected to multiple output ends of the sorting channel 5 is arranged on the bottom side of the rolling cavity. The specifications of the multiple sorting slots are different. The channels, through grooves, rolling grooves for rolling tablets inside the sorting channel 5 and the space of the sorting slots are relatively narrow to prevent the tablets from lying flat and being blocked. The size of the sorting slots increases from the back to the front to prevent small-sized tablets from falling into large-sized sorting slots.

[0049] Specifically, the guiding slope helps the stacked tablets on the alignment frame 4 to tilt at the opening, and with the help of the slight vibration generated by the rotation of the wheel 3, it is easier to enter the opening in a vertical state. When the wheel 3 drives the alignment frame 4 to rotate and displace, the tablets in the stacked cylinder 2 are subjected to slight vibrations under the influence of the rotation of the wheel 3, changing the stacking state, so that some of the tablets at the bottom are arranged vertically and enter the alignment frame 4, and when they are displaced to the through groove of the cylinder 2, they fall into the sorting channel 5, and roll along the slope inside the sorting channel 5. During the rolling process, the tablets that meet the specifications enter the sorting slot inside the sorting channel 5, and the tablets that are larger than the sorting slot at this position continue to roll until they enter the corresponding sorting slot and fall into the guide frame 6 along the discharge port. The metering valve 7 on the guide frame 6 controls the opening and closing of the output end, and the tablets are poured into the medicine bottles transported by the medicine bottle conveyor belt 8. By arranging the tablets into a vertical rollable posture, the size of the tablets is determined when the tablets roll through the sorting slot during transportation inside the sorting channel 5. The tablets that meet the size of the sorting slot will be sorted by falling from the entrance of the sorting slot. The tablets can be sorted quickly and the loading work can be completed, which improves the work efficiency and the efficiency and accuracy of sorting.

[0050] Please see attached Fig.16 During the unloading period, the medicine bottle conveyor belt 8 will stop conveying to cooperate with the unloading. After the unloading of the medicine bottle is transported to the end of the medicine bottle conveyor belt 8, it falls on the belt body 12. The anti-tilt ring 9 is located on the top side of the belt body 12, so that the medicine bottle can fall along the anti-tilt ring 9 after being transported to the end of the medicine bottle conveyor belt 8, thereby avoiding the phenomenon of the medicine bottle tipping over and spilling the tablets.

[0051] Please see attached Fig. 9 -Attached Fig.11, multiple guardrail frames 10, the left end of the guardrail frame 10 is provided with a conveyor belt for conveying medicine bottles filled with tablets, the conveyor belt is composed of toothed rollers 11 and belt bodies 12 which are rotatably connected to the front and rear ends of the guardrail frame 10 respectively, the front toothed roller 11 is fixedly connected to the outer wall of the rotating shaft 14, the rear toothed roller 11 is fixedly connected to the outer wall of the driving shaft 13, the toothed rollers 11 at both ends are connected through the belt body 12, the belt body 12 is meshed with the toothed rollers 11 at both ends through the teeth on the inner periphery, and a feeding tray 17 is rotatably connected to the right side of the front end of the guardrail frame 10, and a plurality of grooves for receiving medicine bottles are provided on the outer periphery of the feeding tray 17. As the feeding tray 17 rotates To drive the medicine bottles to perform packaging operations, the rear ends of the multiple conveyor belts are connected through a driving shaft 13, and the front ends of the multiple conveyor belts are connected through a rotating shaft 14 to synchronize the transmission progress and efficiency. The transmission shaft 18 located at the bottom side of the feeding tray 17 is connected to the right side of the guardrail frame 10, and the front end of the transmission shaft 18 is connected to the rotating shaft 14 through two meshing bevel gears, and the rear end of the transmission shaft 18 is connected to a missing gear 19 through two meshing bevel gears. A gear 2 20 is provided on the rear side of the missing gear 19, and the top side of the missing gear 19 is rotationally connected to the guardrail frame 10, and the gear 2 20 is fixedly connected to the bottom side of the feeding tray 17;

[0052] Specifically, the belt body 12 is divided into a two-layer structure. The inner layer is used for transmission and is provided with teeth. The outer layer has a rough surface to increase the friction with the medicine bottles. The belt body 12 is in a taut state and has a certain thickness. It can stably bear the weight of a large number of medicine bottles without bending. The belt body 12 is displaced, and the toothed roller 11 at the front end connected to the rotating shaft 14 is rotated. The rotating shaft 14 sequentially drives the transmission shaft 18 and the missing gear 19 to rotate through the meshing bevel gears. The missing gear 19 indirectly meshes with the gear 20 connected to the feeding tray 17 to rotate. After the medicine bottle on the belt body 12 is stuck in the groove on the feeding tray 17, the rotating feeding tray 17 drives the medicine bottle to be displaced through the groove and detaches from the top side of the belt body 12. The next vacant groove continues to receive the material. The medicine bottle passes through the bottom side of the bottle cap feeder and the bottle cap tightening device 23 in turn to be packaged. The packaged medicine bottle is transported back to the belt body 12 by the feeding tray 17, and the belt body 12 transports the medicine bottle to the end.

[0053] Please see attached Fig.10 and attached Fig.12 , a piston cylinder 21, wherein two interconnected air chambers are provided inside the piston cylinder 21, wherein a piston 1 22 is slidably connected inside one of the air chambers, and a piston 26 is slidably connected inside the other air chamber, wherein the piston 1 22 is supported by a spring, and a bottle cap tightening device 23 for sealing and tightening the bottle cap of the medicine bottle is installed on the top side of the piston 1 22, and a missing gear 25 is arranged on the rear side of a rack 24 fixedly connected to the rear side of the piston 1 22, and the missing gear 25 is connected to the rotating shaft 14 by two pulleys 1 driven by the inner side of a cross belt;

[0054] Specifically, a group of pulleys 2 driven by a cross belt on the rotating shaft 14 will drive the missing gear 25 to rotate, indirectly meshing with the rack 24 connected to the piston 1 22, causing the piston 1 22 to move downward, and the bottle cap tightening device 23 connected to the piston 1 22 moves downward and rotates to tighten the bottle cap. The downwardly displaced piston 1 22 compresses the connected spring and the air in the extrusion piston cylinder 21, so that the air is squeezed from one air cavity into another air cavity, and the piston 26 in the other air cavity is lifted up. The sliding parts of the piston 1 22 and the piston 2 26 are both anti-rotation special-shaped structures, and a rubber ring is provided at the bottom to avoid air leakage and maintain the squeezing and retraction of the gas. When the missing gear 25 is separated from the rack 24, the compressed spring will lift and reset the piston 1 22 again, and the gas is drawn back into the original air cavity to reset the piston 26.

[0055] Please see attached Fig.13 and attached Fig.15 The rear side of the top end of the piston 26 is fixedly connected with a resistance frame 27 for triggering the bottle cap feeder to lower the bottle cap. The inside of the material storage basket 28 located at the rear side of the piston cylinder 21 is slidably connected with a pressure plate 29 through a spring. The front right side of the material storage basket 28 is slidably connected with a resistance member 30 through a spring. The resistance frame 27 is located at the top side of the resistance member 30. The resistance frame 27 and the resistance member 30 are both provided with inclined surfaces on the side close to each other. The two inclined surfaces abut against each other. The left side of the resistance member 30 passes through the inner wall of the material storage basket 28.

[0056] Specifically, the storage basket 28 contains multiple rows of neatly stacked bottle caps, which are pressed tightly by multiple pressure plates 29 connected to springs to prevent tipping. When a part of the frontmost row is vacant, the pressure plate 29 at that height is refilled under the push of the compressed spring. The rising piston 26 rises together with the resistance frame 27 connected to it, and the inclined surface structure on the bottom side of the resistance frame 27 releases the contact with the inclined surface of the resistance member 30. The spring connected to the resistance member 30 is normally in a compressed state. When the inclined surface structure on the bottom side of the resistance frame 27 gradually releases the contact with the inclined surface of the resistance member 30, the compressed spring will push the resistance member 30 to move outward, releasing the contact and fixation of the bottle caps inside the material storage basket 28, so that the bottle caps fall on the medicine bottles, and the subsequent bottle caps continue to be stacked on the fallen bottle caps. Before the medicine bottles move away, the reset piston 26 drives the resistance frame 27 to reset, thereby causing the inclined surface structure on the bottom side of the resistance frame 27 to press down the inclined surface of the resistance member 30 again, so that the resistance member 30 again presses against the bottle caps at the discharge port of the material storage basket 28.

[0057] Please see attached Figure 2 and attached Figure 3The bottom sides of the storage tank 1, the cylinder 2, the guardrail frame 10, and the bottle cap feeder are all fixed to the top side of the base. The rear end of the base is equipped with a motor 15 as a driving source. The motor 15 synchronously drives the collecting wheel and the driving shaft 13 to rotate synchronously through a transmission member. The transmission member is composed of two mutually meshing gears 16 and two pulleys 2, one of which is fixedly connected to the outer wall of the driving shaft 13, and the left side of the other gear 16 is connected to the driving end of the motor 15, and the other gear 16 is connected to the rotating wheel 3 by two pulleys 2 driven by the inner side of the belt;

[0058] Specifically, when the motor 15 is started, the motor 15 will drive the gear 16 on the driving end to rotate, and at the same time drive another gear 16 connected to the driving shaft 13 to rotate and the connected pulley 1 to rotate. The pulley 1 is synchronously rotated with another pulley 1 connected to the rotating wheel 3 through a belt drive to drive the rotating wheel 3 to rotate. When the rear end toothed roller 11 driven by the rotating driving shaft 13 rotates, the synchronous transmission belt body 12 is displaced, and the front end toothed roller 11 connected to the rotating shaft 14 is rotated.

[0059] Please see attached Figure 1 and attached Fig.17 The transparent frame 31 is made of transparent hard plastic as raw material, and the transparent frame 31 is fixedly connected to the front side of the base. A plurality of collection boxes 33 are arranged inside the transparent frame 31. The transparent frame 31 can better observe the situation of the collection box 33 inside, and then judge whether the collection box 33 is full of medicine bottles. The top rear end of the transparent frame 31 is fixedly connected with a feeding port 32, and the feeding port 32 is located on the side close to the front end of the belt body 12 and the collection box 33. The top front end of the transparent frame 31 is fixedly connected with a gas channel 34, and the gas channel 34 is connected with the interior of the transparent frame 31. The air inlet of the rotating shaft 14 is connected to the air outlet of the storage tank 1 through a pipeline. The medicine bottles transported to the end of the belt body 12 will fall into the feeding port 32 and be collected by the collection box 33. The full collection box 33 can be pulled out to replace the idle collection box 33. The excess low-temperature ozone gas for disinfection in the storage tank 1 will also enter the gas channel 34 connected to the transparent frame 31 through the pipeline, and disinfect the medicine bottles in the collection box 33 in the transparent frame 31 again, thereby increasing the utilization rate of ozone and reducing ozone consumption.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
