Description

Technical Field

[0001] The present application relates to the technical field of drug packaging, and in particular to a packaging mechanism of an automatic dispensing system for oral medications in the sepsis recovery period. Background Art

[0002] Sepsis is a systemic inflammatory response syndrome caused by infection and is an extremely dangerous condition. Even if the patient survives the critical period and enters the recovery period, systemic treatment with oral medication is still required. At this stage, the use of antibiotics is still critical - doctors will accurately select sensitive antibiotics based on the results of pathogen culture and drug sensitivity tests, and administer them orally in small doses over a long course of treatment. The type and dosage of drugs must be strictly controlled. In the routine process, nurses need to go to the pharmacy to pick up the drugs. Manual preparation is not only inefficient and difficult to achieve mass customization, but also prone to dosage errors, drug mismatches and other problems. To this end, the existing technology proposes the establishment of an automatic drug dispensing system to solve the problems of drug dispensing efficiency and drug mismatches. The system includes a drug storage unit, a metering unit and a packaging mechanism. The packaging mechanism of the traditional automatic medicine dispensing system is equipped with a hot-melt packaging structure, which is consistent with the structure of the existing food packaging machine and is mainly composed of a feeding part, a transverse heat-sealing part and a longitudinal heat-sealing part; the existing packaging mechanism will also add an image detection part at the end for identifying medicines. This image detection part is built based on existing conventional machine vision technology. It uses a high-definition camera to collect image information at the exit of the packaging mechanism in real time and dynamically monitor the number of tablets in the packaging bag.

[0003] However, in the actual process of taking medicine, it is often the case that multiple medical staff take medicine at the same time. The sheet medicine is packaged by the hot-melt packaging structure and then exported to the outside. When the packaging bag has problems such as its own quality problems or the hot-melt packaging structure has been running at too high a temperature for a long time, the packaging bag may break and get stuck, and the medicine cannot be discharged normally, and then the tablets fall into the machine and cause waste; if the packaging bag breaks, if the fault is not triggered and maintained quickly in time, the broken packaging bag and residual medicine will accumulate and become extremely difficult to clean up. The long subsequent downtime for maintenance will easily affect the speed at which medical staff take medicine. Therefore, there is an urgent need to add a detection structure in the packaging mechanism to identify the stuck state of the packaging bag. Summary of the Invention

[0004] This device provides a packaging mechanism for an automatic dispensing system for oral medications during the sepsis recovery period. The specific implementation is as follows:

[0005] The packaging mechanism of the automatic dispensing system for oral medication in the sepsis recovery period includes:

[0006] A support and a conveyor belt structure provided on the support;

[0007] A detection wheel structure is provided above the conveyor belt structure, and both the detection wheel structure and the conveyor belt structure are connected to the motor through a synchronous transmission structure;

[0008] A proximity switch is provided on the side of the bracket, and the detection wheel structure includes a hinged plate that is vertically connected to the side of the bracket. One end of the hinged plate is connected to the crimping wheel through a rotating shaft. The synchronous transmission structure is used to drive the rotating shaft to rotate. The other end of the hinged plate is adapted to be connected with the proximity switch. When a packaging bag passes between the crimping wheel and the conveyor belt structure, the crimping wheel is lifted, the proximity switch does not generate a signal, and the motor operates normally. When no packaging bag passes between the crimping wheel and the conveyor belt structure, the crimping wheel falls, the proximity switch generates a signal, and the motor stops running.

[0009] Based on the above technical solution, during the feeding and conveying process of the packaging bags, idling detection is achieved by setting up a synchronously running crimping wheel, that is, when the packaging bags are not fed normally, the proximity switch is not triggered, and the motor is shut down, as well as regular alarm reminders and remote prompts to ensure the safety of the packaging mechanism operation; the crimping wheel is made of sponge material, and is set to have a wavy pattern along the circumference.

[0010] Preferably, the bracket includes a first frame body and a second frame body that are rotatably connected to each other, and a telescopic cylinder for adjusting the angle is provided between the first frame body and the second frame body.

[0011] Preferably, a locking cylinder is hingedly provided at the air arm end of the telescopic cylinder, and the inner end surface of the locking cylinder is movably abutted against the end surface of the cylinder body of the telescopic cylinder.

[0012] Based on the above technical solution, the air arm end of the telescopic cylinder is hingedly provided with a locking cylinder, which can be flipped down and sleeved on the air arm. After the air arm is extended, the end of the locking cylinder abuts against the end face of the cylinder body of the telescopic cylinder, so that the air arm of the telescopic cylinder is locked to the first frame after it is extended.

[0013] The second conveyor belt, the third conveyor belt and the first conveyor belt are arranged in sequence, one end of the second conveyor belt corresponds to the outlet of the hot melt packaging structure, and there is an angle between the second conveyor belt and the third conveyor belt, and between the third conveyor belt and the first conveyor belt, and the crimping wheel is located at the angle.

[0014] Preferably, the side of the second frame is provided with a first transmission shaft, a third transmission shaft and a second transmission shaft that are meshed with each other through gears. The second transmission shaft and the output end of the motor, and the first transmission shaft and the first conveyor belt are connected through belt transmission, and the second transmission shaft is coaxially connected to the second conveyor belt and the third conveyor belt.

[0015] Based on the above technical solution, a single motor is used to control the synchronous rotation of the first conveyor belt, the second conveyor belt and the third conveyor belt, and the three conveyor belts are composed of a number of sub-conveyor belts arranged at equal intervals along their width direction; the crimping wheel can not only perform a lifting operation, but also limit the feeding packaging bags at this angle.

[0016] Preferably, a fixed shaft is further provided on the side of the second frame, and the fixed shaft is rotatably connected to the hinge plate.

[0017] Preferably, a first rotating cylinder and a second rotating cylinder are respectively rotatably provided on the inner sides of both ends of the hinged plate, and the first rotating cylinder and the second rotating cylinder are connected by a first transmission belt; the first rotating cylinder is coaxially connected to the rotating shaft, the second rotating cylinder is coaxially connected to the fixed shaft, and the second rotating cylinder and the third transmission shaft are connected by belt transmission.

[0018] Based on the above technical solution, a single motor is used to not only drive the conveyor belt, but also synchronously drive the crimping wheel, ensuring that the speeds of the two are consistent.

[0019] Preferably, a pressure plate structure and a pressure wheel structure acting on the thermoplastic position of the packaging bag are respectively provided above the first conveyor belt along its width direction; the pressure wheel includes a small corrugated wheel and a large corrugated wheel arranged coaxially, both of which are installed on the rotating shaft through a locking pin, and the large corrugated wheel acts on the thermoplastic position of the packaging bag.

[0020] Based on the above technical solution, the pressure wheel structure cooperates with the first conveyor belt to extrude and feed the thermoplastic line position of the packaging bag. The pressure plate structure includes a pressure plate and a second torsion spring. The pressure plate structure smoothes the drug-containing packaging bag during the feeding process so that the tablets in the packaging bag are flat for subsequent re-inspection by the image detection unit.

[0021] Preferably, the proximity switch has a U-shaped opening structure, a photoelectric switch is provided in the opening, and the trigger plate is actively matched with the opening.

[0022] Preferably, a torsion spring structure is provided at the rotation point between the bracket and the hinge plate, which assists the hinge plate to automatically fall when no packaging bag passes by. When a packaging bag passes by, the hinge plate and the crimping wheel are lifted and the torsion spring structure is deformed.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. This utility model provides a detection wheel structure at the end of the hot melt packaging structure. When a packaging bag passes by, the crimping wheel rises. If the packaging bag breaks and cannot enter the conveyor belt structure, the crimping wheel lowers and triggers the proximity switch to respond. The motor stops in time, avoiding the loss of a large number of tablets due to continued dispensing.

[0025] 2. The utility model uses a single motor and a synchronous transmission structure to achieve synchronous driving of the first, second, and third conveyor belts. This not only enables the synchronous conveying of pharmaceutical bags, but also forms a U-shaped matching angle between the three conveyor belts and the crimping wheel, making it easier for the crimping wheel to push the bags outward, and also rationally utilizing the internal space of the packaging mechanism as a whole.

[0026] 3. The utility model has a simple structure. Through a single motor and a synchronous transmission structure, the detection wheel structure and the conveyor belt structure can rotate synchronously. That is, the crimping speed of the crimping wheel on the packaging bag is consistent with the feeding speed of the packaging bag, effectively avoiding the deviation of the packaging bag caused by the speed difference.

[0027] 4. The utility model realizes the adjustment of the packaging unloading angle of the first conveyor belt by setting the bracket into two sections with the help of a telescopic cylinder, and the telescopic cylinder is provided with a locking cylinder for locking the angle.

[0047] The following is combined with Figure 1-8 This application is described in further detail.

[0048] The embodiments of the present application disclose a packaging mechanism of an automatic dispensing system for oral medications in the sepsis recovery period.

One end of the hinged plate 203 is connected to the crimping wheel 201 through the rotating shaft 202, and the other end is adapted to be connected to the proximity switch 5 through the trigger plate 204. When a packaging bag passes between the crimping wheel 201 and the conveyor belt structure 8, the crimping wheel 201 is lifted and the motor 4 operates normally. When no packaging bag passes between the crimping wheel 201 and the conveyor belt structure 8, the crimping wheel 201 falls and the motor 4 stops running.

When the packaging bag breaks, the tension is lost, and the pressing wheel 201 is quickly reset under the action of the torsion spring structure, thereby realizing the rapid triggering of the proximity switch 5 when the bag breaks.

[0052] Combine Figures 5 to 7 The side of the second frame 102 is also provided with a fixed shaft 306, which is rotatably connected to the hinge plate 203.

[0054] The specific implementation process is as follows: after the hot-melt packaging structure seals the tablets in the packaging bag, the packaging bag forms several independent cavities with tablets along its length; after the motor 4 is started, the first conveyor belt 801, the second conveyor belt 802 and the third conveyor belt 803 rotate synchronously to convey the sealed packaging bag to the side close to the image detection unit 10; during this period, the packaging bag passes through the crimping wheel 201 and is lifted with the help of the hinge plate 203, while the trigger plate 204 at the other end of the hinge plate 203 descends; when the packaging bag breaks, no packaging bag passes through the crimping wheel 201, the crimping wheel 201 falls, and the trigger plate 204 flips up, triggering the response of the proximity switch 5.
