Description

Technical Field

[0001] The present invention relates to the technical field of intelligent drug sub-packaging machines, and particularly to a traction device for measuring the traction synchronization degree of medicine bags of an intelligent drug sub-packaging machine. Background Art

[0002] With the rapid development of the pharmaceutical industry, the traditional manual medicine dispensing method is difficult to meet the improvement of hospital pharmacy management level and the requirements for pharmacy work in the new century. The new medicine dispensing mode fully reflects the overall strength of the hospital, ensures more accurate medicine dispensing, can provide more comprehensive and high-quality services for clinical departments, improves service quality and work efficiency, and can provide reliable data basis for high-level pharmacy management. The Automatic Tablet Dispensing System (ATDPS), which is an innovative pharmacy solution, realizes safe and stable automated operation through new hospital and pharmacy management and the use of efficient and accurate data processing processes. From selecting the correct drugs to storing, counting, filling, and packaging the drugs, the ATDPS can fully automate all operations of the medicine dispensing process. Moreover, after inputting the medication order (MO) provided by the hospital or pharmacy into the system, relevant information and medication instructions can be printed according to the patient's MO to better serve the patients.

[0003] At present, when the intelligent drug sub-packaging machine used in the market is in use, since the heat generated by the heat-sealing mechanism will cause a certain deformation of the medicine bag, and the medicine bag has no deformation when the printing mechanism prints first or later, it will cause an error in the pulling stroke of the printer on the medicine bag and the pulling stroke of the hot air blower on the medicine bag. When the error is small, it can be temporarily not adjusted, but when the errors accumulate, it will cause the printer to print on other medicine bags, or the heat-sealing position of the heat-sealing mechanism is inaccurate, resulting in unsealed medicine bags and inaccurate cutting.

[0004] If it prints on other medicine bags, the drug information will be inaccurate, and patients will take the wrong medicine, causing serious doctor-patient problems; if the heat-sealing and cutting are inaccurate, the drugs cannot be packaged.

[0005] Under the current situation, when the error is slightly larger, the above problems can only be solved by stopping the machine for manual correction and adjusting the initial position of the medicine bag. In view of the above problems, our company has developed a synchronization degree measurement traction device to provide digital signals to the upper computer and assist in solving the problem of automated synchronization adjustment. Summary of the Invention

[0006] The object of the present invention is to provide an intelligent medicine sub-packaging machine medicine bag traction synchronization measurement and traction device with a simple structure, reasonable design and convenient use in view of the defects and deficiencies of the prior art. It includes a bracket, a bearing, two guide shafts, a magnet, a Hall PCB board, a tension spring pull rod, a tension spring, a hanging rod, a tension shaft, a rotating shaft, and a tension shaft bottom plate; the bearing, the guide shaft, the Hall PCB board and the hanging rod are all installed on the bracket; a rotating shaft is installed in the bearing, the tension shaft bottom plate is fixed on the rotating shaft, one end of the tension spring pull rod is installed at the bottom of the rotating shaft, and the other end is elastically connected between the tension spring and the hanging rod; the magnet is pasted at the bottom of the tension spring pull rod, and the Hall PCB board is located below the magnet for detecting the rotation angle of the magnet; the tension shaft is installed on the tension shaft bottom plate. When the tension shaft is located between the connecting lines of the two guide shafts, the tension spring deforms, and without external interference, it pulls the tension spring pull rod and the rotating shaft to drive the tension shaft bottom plate and the tension shaft to rotate around the center of the rotating shaft, and at the same time drives the magnet to rotate.

[0007] The intelligent medicine sub-packaging machine medicine bag traction synchronization measurement and traction device described in the present invention is installed between the medicine bag sealing mechanism and the medicine bag printer. When in use, the medicine bag is passed through between the two guide shafts and the tension shaft, and the reset force of the tension spring is used to pull the medicine bag through the tension shaft to form an S shape, combined with the traction forces of the medicine bag sealing mechanism and the printer to form a force balance. When the printer and the medicine bag sealing mechanism have different traction distances due to deformation caused by heat sealing, the tension of the medicine bag will change, resulting in the rotation of the tension shaft around the rotating shaft. The rotating shaft drives the magnet to rotate, and the magnetic pole position of the magnet changes. The Hall PCB board can detect the change angle of the magnetic pole, and thus transmit the variable to the upper computer. The upper computer calculates the variable of the medicine bag displacement through the angle change, that is, the traction error between the printer and the medicine bag sealing mechanism. The upper computer can send an instruction to drive the printer to unidirectionally adjust the traction length to make up for the above error, so that the traction of the printer and the medicine bag sealing mechanism is restored to the initial synchronous position. After adopting the above structure, the beneficial effect of the present invention is that it solves the problem of asynchronous traction of the medicine bag by the printer and the medicine bag sealing mechanism of the intelligent medicine sub-packaging machine, and can complete automatic synchronous correction without stopping the machine, greatly improving the working efficiency of the sub-packaging machine.

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions are only used to explain the present invention, but not to limit the present invention.

[0015] As Figures 1-3 shown, the medicine bag traction synchronization measurement traction device of the intelligent medicine sub - packaging machine described in this specific implementation manner includes a bracket 1, a bearing 2, two guide shafts 3, a magnet 4, a Hall PCB board 5, a tension spring pull rod 6, a tension spring 7, a hanging rod 8, a tensioning shaft 9, a rotating shaft 10, and a tensioning shaft bottom plate 11; the bearing 2, the guide shaft 3, the Hall PCB board 5, and the hanging rod 8 are all installed on the bracket 1; the rotating shaft 10 is installed in the bearing 2, the tensioning shaft bottom plate 11 is fixed on the rotating shaft 10, one end of the tension spring pull rod 6 is installed at the bottom of the rotating shaft 10, and the other end is elastically connected between the tension spring 7 and the hanging rod 8; the magnet 4 is pasted at the bottom of the tension spring pull rod 6, and the Hall PCB board 5 is located below the magnet 4 for detecting the rotation angle of the magnet 4; the tensioning shaft 9 is installed on the tensioning shaft bottom plate 11. When the tensioning shaft 9 is located between the connection lines of the two guide shafts 3, the tension spring 7 deforms, and without external interference, it pulls the tension spring pull rod 6 and the rotating shaft 10 to drive the tensioning shaft bottom plate 11 and the tensioning shaft 9 to rotate around the center of the rotating shaft 10, and at the same time drives the magnet 4 to rotate.

[0016] The medicine bag traction synchronization measurement traction device of the intelligent medicine sub - packaging machine described in this specific implementation manner is installed on the medicine sub - packaging machine frame with the bracket 1 during use, located between the medicine bag printer and the sealing mechanism of the medicine sub - packaging machine. With the assistance of external force, the tensioning shaft 9 is pushed to rotate around the rotating shaft 10. Manually pass the medicine bag 100 through the printer and then through between the two guide shafts 3 and the tensioning shaft 9. At this time, refer to Figure 2 ; then pass the medicine bag into the sealing mechanism. After both ends of the medicine bag are tightened by the printer and the sealing machine, release the tensioning shaft 9. The tension spring 7 pulls the tension spring pull rod 6 to rotate around the rotating shaft 10, driving the tensioning shaft bottom plate 11 and the tensioning shaft 9 to reset. At this time, under the combined action of the pulling force of the tension spring 7 and the pulling forces at both ends of the medicine bag 100, the medicine bag 100 and the tensioning shaft 9 are relatively stable, as Figure 3; Then, pull the medicine bag 100 to adjust the initial printing position and the initial heat-sealing position of the medicine bag 100. After starting the machine, the printer and the heat-sealing machine synchronously pull the medicine bag 100. First, print the name of the medicine. After the medicine bag 100 passes through this traction device, receive the medicine and then seal and cut it by the heat-sealing machine.

[0017] Whether due to the self-transmission error of the printer or the heat-sealing machine, or because of the thermal expansion and contraction error of the medicine bag 100 during heat-sealing, there are only two cases of asynchronous transmission:

[0018] 1. The pushing distance of the printer on the medicine bag 100 exceeds the pulling distance of the heat-sealing machine. At this time, the medicine bag between the printer and the heat-sealing machine will become loose. At this time, the pulling force of the medicine bag 100 on the tension shaft 9 changes. The tension shaft 9 rotates counterclockwise around the rotating shaft 10 under the pulling force of the tension spring 7. At the same time, the magnet 4 attached under the tension spring rod 6 also rotates counterclockwise, and the magnetic pole position changes. The Hall PCB board 5 detects the change of the magnetic pole position and transmits the signal to the upper computer. The upper computer controls the printer to retract the medicine bag 100 according to the set instructions to correct the error. The actual retraction length can be calculated according to the rotation angle of the magnetic pole. Since the company has applied for the corresponding software copyright for the program control part, it will not be elaborated in detail here.

[0019] 2. The pushing distance of the printer on the medicine bag 100 is less than the pulling distance of the heat-sealing machine. At this time, the medicine bag between the printer and the heat-sealing machine will be tightened. Since the medicine bag 100 is tightened, the pulling force of the medicine bag 100 on the tension shaft 9 changes. At this time, the tension shaft 9 rotates clockwise around the rotating shaft 10. At the same time, the magnet 4 attached under the tension spring rod 6 also rotates clockwise, and the magnetic pole position changes. The Hall PCB board 5 detects the change of the magnetic pole position and transmits the signal to the upper computer. The upper computer controls the printer to push an additional section of the medicine bag 100 according to the set instructions to correct the error. The actual additional pushing length can be calculated according to the rotation angle of the magnetic pole. Since the company has applied for the corresponding software copyright for the program control part, it will not be elaborated in detail here.

[0020] Preferably: A rubber sleeve is provided on the outer surface of the tension shaft 9. The rubber sleeve increases the friction between the tension shaft 9 and the medicine bag 100 to prevent the medicine bag 100 from slipping.

[0021] The medicine bag traction synchronization measurement and traction device of the intelligent medicine sub-packaging machine described in the present invention solves the problem of asynchronous traction of the medicine bag by the printer and the medicine bag sealing mechanism of the intelligent medicine sub-packaging machine, and can complete automatic synchronization correction without stopping the machine for correction, greatly improving the working efficiency of the sub-packaging machine.

[0022] The above is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
