Description

Technical Field

[0001] The present invention relates to the technical field of intelligent drug sub-packaging machines, and particularly to a printing and heat-sealing assembly 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, improve 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] Currently, when the intelligent drug sub-packaging machine used in the market is in use, since the heat generated by the heat-sealing assembly causes a certain deformation of the medicine bag, and the medicine bag has no deformation when the printing mechanism prints first or later, it leads to errors 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 assembly seals the bag at an inaccurate position, resulting in unsealed medicine bags and inaccurate shearing.

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

[0005] Currently, 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. Summary of the Invention

[0006] The object of the present invention is to provide an intelligent medicine sub-packaging machine printing and heat-sealing assembly in view of the defects and deficiencies of the prior art. It includes a printer, a medicine dropping gate assembly, a heat-sealing assembly, and a medicine bag shearing device; after the medicine bag is printed by the printer, it passes under the medicine dropping gate assembly, catches the medicine dropped by the medicine dropping gate assembly, and then undergoes heat-sealing packaging through the heat-sealing assembly, and then is pressed and cut by the medicine bag shearing device; it also includes a medicine bag synchronization measurement device, which is installed between the printer and the heat-sealing assembly and is used to detect the traction distance difference of the medicine bag between the printer and the heat-sealing assembly. The medicine bag synchronization measurement device includes a first 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 first bracket; the 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 and is used to detect 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 force 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] In the intelligent medicine sub-packaging machine printing and heat-sealing assembly of the present invention, its medicine bag synchronization measurement device is installed between the printer and the heat-sealing assembly. When the traction distances of the printer and the heat-sealing assembly for the medicine bag are asynchronous, it detects the change in the tightness of the medicine bag between the printer and the heat-sealing assembly. The medicine bag synchronization measurement device bends and stresses the medicine bag. When the tightness of the medicine bag changes, the detection unit of the medicine bag synchronization measurement device can detect the corresponding change amount, that is, detect the traction distance difference of the medicine bag between the printer and the heat-sealing assembly. Then the medicine bag synchronization measurement device feeds back the signal to the upper computer, and the upper computer controls the printer to correct the position of the medicine bag.

[0008] After adopting the above structure, the beneficial effect of the present invention is as follows: The intelligent medicine sub-packaging machine printing and heat-sealing assembly of the present invention solves the problem of asynchronous traction of the medicine bag between the printer of the intelligent medicine sub-packaging machine and the medicine bag heat-sealing assembly, and can complete automatic synchronous correction without stopping the machine, greatly improving the working efficiency of the sub-packaging machine.

Detailed implementation manners

[0020] The present invention will be described in detail below in conjunction with the drawings and specific embodiments, in which the schematic embodiments and descriptions are only used to explain the present invention, but not to limit the present invention.

[0021] Such as Figure 1As shown in the figure, the printing and heat-sealing assembly of the intelligent medicine sub-packaging machine described in this specific embodiment includes a printer 1, a medicine dropping gate assembly 3, a heat-sealing assembly 4, and a medicine bag cutting device 5; after the medicine bag 100 is printed by the printer 1, it passes under the medicine dropping gate assembly 3, catches the medicine dropped by the medicine dropping gate assembly 3, and then undergoes heat-sealing packaging through the heat-sealing assembly 4, and then is cut by the medicine bag cutting device 5; it further includes a medicine bag synchronization measurement device 2, which is installed between the printer 1 and the heat-sealing assembly 4 and is used to detect the difference in the traction distance of the medicine bag 100 by the printer 1 and the heat-sealing assembly 4.

[0022] For the printing and heat-sealing assembly of the intelligent medicine sub-packaging machine described in the present invention, its medicine bag synchronization measurement device 2 is installed between the printer 1 and the heat-sealing assembly 4. When the traction distances of the printer 1 and the heat-sealing assembly 4 for the medicine bag 100 are asynchronous, it detects the change in the tightness of the medicine bag 100 between the printer 1 and the heat-sealing assembly 4. The medicine bag synchronization measurement device 2 bends and applies force to the medicine bag 100. When the tightness of the medicine bag 100 changes, the detection unit of the medicine bag synchronization measurement device 2 can detect the corresponding change amount, that is, detect the difference in the traction distance of the medicine bag 100 by the printer 1 and the heat-sealing assembly 4. Then the medicine bag synchronization measurement device 2 feeds back the signal to the upper computer, and the upper computer controls the printer 11 to correct the position of the medicine bag 100. The corresponding software copyright for this electronic control program part has been applied for by our company and will not be elaborated here.

[0023] Preferably: as Figures 2-4 , the medicine bag synchronization measurement device 2 includes a first bracket 2-1, a bearing 2-2, two guide shafts 2-3, a magnet 2-4, a Hall PCB board 2-5, a spring pull rod 2-6, a spring 2-7, a hanging rod 2-8, a tensioning shaft 2-9, a rotating shaft 2-10, and a tensioning shaft bottom plate 2-11; the bearing 2-2, the guide shafts 2-3, the Hall PCB board 2-5, and the hanging rod 2-8 are all installed on the first bracket 2-1; the rotating shaft 2-10 is installed in the bearing 2-2, the tensioning shaft bottom plate 2-11 is fixed on the rotating shaft 2-10, one end of the spring pull rod 2-6 is installed at the bottom of the rotating shaft 2-10, and the other end is elastically connected between the spring 2-7 and the hanging rod 2-8; the magnet 2-4 is pasted at the bottom of the spring pull rod 2-6, and the Hall PCB board 2-5 is located below the magnet 2-4 and is used to detect the rotation angle of the magnet 2-4; the tensioning shaft 2-9 is installed on the tensioning shaft bottom plate 2-11. When the tensioning shaft 2-9 is located between the connection lines of the two guide shafts 2-3, the spring 2-7 deforms, and without external force interference, it pulls the spring pull rod 2-6 and the rotating shaft 2-10 to drive the tensioning shaft bottom plate 2-11 and the tensioning shaft 2-9 to rotate around the center of the rotating shaft 2-10, and at the same time drives the magnet 2-4 to rotate.

[0024] When in use, it is installed on the medicine sub-packaging machine frame by the bracket 2-1, located between the medicine bag printer 1 and the heat-sealing assembly 4 of the medicine sub-packaging machine. With the assistance of external force, the tensioning shaft 2-9 is pushed to rotate around the rotating shaft 2-10. Manually pass the medicine bag 100 through the printer 1 and then through the two guide shafts 2-3 and the tensioning shaft 2-9. At this time, refer to Figures 2-4 ; then pass the medicine bag 100 into the heat-sealing assembly 4. After both ends of the medicine bag are tightened by the printer 1 and the heat-sealing assembly 4, release the tensioning shaft 2-9. The tension spring 2-7 pulls the tension spring pull rod 2-6 to rotate around the rotating shaft 2-10, driving the tensioning shaft bottom plate 2-11 and the tensioning shaft 2-9 to reset. At this time, under the combined action of the tension of the tension spring 2-7 and the tensions at both ends of the medicine bag 100, the medicine bag 100 and the tensioning shaft 2-9 are relatively stable, as Figure 4 ; 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 1 and the heat-sealing assembly 4 synchronously pull the medicine bag 100, first print the medicine name. After the medicine bag 100 passes through the medicine bag synchronization measurement device 2, it receives the medicine and then is sealed by the heat-sealing assembly 4 and cut by the medicine bag cutting device 5.

[0025] Whether it is due to the self-transmission error of the printer 1 or the heat-sealing assembly 4, or because of the thermal expansion and contraction error of the medicine bag 100 during heat-sealing, there are only two situations for transmission non-synchronization:

[0026] 1. The pushing distance of the printer 1 for the medicine bag 100 exceeds the pulling distance of the heat-sealing assembly 4. At this time, the medicine bag 100 between the printer 1 and the heat-sealing assembly 4 will become loose. At this time, the tension of the medicine bag 100 on the tensioning shaft 2-9 changes. The tensioning shaft 2-9 rotates counterclockwise around the rotating shaft 2-10 under the tension of the tension spring 2-7. At the same time, the magnet 2-4 attached under the tension spring pull rod 2-6 also rotates counterclockwise, and the pole position changes. The Hall PCB board 2-5 detects the change of the pole position and transmits the signal to the upper computer. The upper computer controls the printer 1 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 pole. Since the company has applied for the corresponding software copyright for the program control part, it will not be elaborated in detail here.

[0027] 2. The pushing distance of the printer 1 to the medicine bag 100 is less than the pulling distance of the heat-sealing assembly 4. At this time, the medicine bag 100 between the printer 1 and the heat-sealing assembly 4 will be tightened. Since the medicine bag 100 is tightened, the tension of the medicine bag 100 on the tensioning shaft 2-9 changes. At this time, the tensioning shaft 2-9 rotates clockwise around the rotating shaft 2-10. At the same time, the magnet 2-4 attached under the tension spring rod 2-6 also rotates clockwise, and the magnetic pole position changes. The Hall PCB board 2-5 detects the change of the magnetic pole and transmits the signal to the host computer. The host 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 length of the additional push 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.

One end of the motor arm 3-3 is fixed on the rotating shaft of the gate motor 3-1, and the other end is hinged to the gate connecting rod 3-4; the other end of the gate connecting rod 3-4 is hinged to the gate 3-5; a chute corresponding to the gate 3-5 is provided in the gate bracket 3-7. The gate motor 3-1 pulls the gate 3-5 to reciprocate in the chute of the gate bracket 3-7 through the motor arm 3-3 and the gate connecting rod 3-4, so as to cut off and open the medicine dropping channel 3-8 provided in the gate bracket 3-7.

[0029] When the medicine bag 100 is in place below the gate 3-5, the gate motor 3-1 drives the motor arm 3-3 to rotate, and pulls open the gate 3-5 through the gate connecting rod 3-4. As Figure 6 in the state, the medicine feeding mechanism at the upper part of the medicine dropping gate assembly 3 drops the medicine into the medicine bag 100; the advantage of this design is that even if the medicine bag 100 is not in place and the gate 3-5 is not opened, the medicine will not drop when the medicine feeding mechanism misfeeds the medicine.

[0030] Preferably: As Figures 5-6 , the medicine dropping gate assembly 3 further includes a photoelectric detection device 3-2. The signal shielding disc of the photoelectric detection device 3-2 is installed on the rotating shaft of the gate motor 3-1, and the signal transmitting and receiving unit of the photoelectric detection device 3-2 is installed on the gate bracket 3-7. A notch corresponding to the signal transmitting and receiving unit is provided on the signal shielding disc of the photoelectric detection device 3-2. The gate motor 3-1 drives the shielding disc to rotate, and changes the signal on-off between the transmitting and receiving units through the displacement of the notch on the shielding disc.

[0031] This design can verify whether the gate 3-5 is opened and closed. Refer to Figure 5When the time notch is located at the transmitting and receiving units, the signal can pass through, and at this time, the gate 3-5 is completely closed; refer to Figure 6 When the time notch is far away from the transmitting and receiving units, the signal is blocked, and at this time, the gate 3-5 is opened.

[0032] Preferably: as Figures 5-6 , the medicine dropping gate assembly 3 further includes a guiding funnel 3-6, and the guiding funnel 3-6 is installed below the medicine dropping channel 3-8. The medicine dropping channel 3-8 plays a guiding role for the medicine grains.

[0033] Preferably: as Figures 7-8 , the medicine bag cutting device 5 includes a motor 5-1, a rotating arm 5-2, a connecting arm 5-3, a pull rod 5-4, a scissor blade connecting piece 5-5, a half-threaded bolt 5-6, scissor blades 5-7, and a second bracket 5-8; the motor 5-1 is installed on the second bracket 5-8, the rotating arm 5-2 is installed on the motor rotating shaft, the eccentric position of the rotating arm 5-2 is hinged to one end of the connecting arm 5-3, and the other end of the connecting arm 5-3 is hinged to the pull rod 5-4; the ends of the two scissor blades 5-7 are respectively hinged to the other end of the pull rod 5-4 through the scissor blade connecting piece 5-5; after the half-threaded bolt 5-6 passes through the shaft holes of the two scissor blades 5-7, it is threadedly fixed to the second bracket 5-8; when the motor 5-1 drives the rotating arm 5-2 to rotate, when the hinge pin of the rotating arm 5-2 and the connecting arm 5-3 is farthest from the half-threaded bolt 5-6, the two scissor blades 5-7 bite; when the hinge pin of the rotating arm 5-2 and the connecting arm 5-3 is closest to the half-threaded bolt 5-6, the two scissor blades 5-7 separate. It uses a unidirectionally rotating motor 5-1 to drive the rotating arm 5-2 to rotate. Through the eccentric installation design, when the rotating arm 5-2 rotates, the pull rod 5-4 is pulled up and down through the connecting arm 5-3. When the pull rod 5-4 moves up and down, the scissor blades are driven to close and open through the closing and opening of the connecting piece, so as to realize the function of cutting the medicine bag.

[0034] Preferably: as Figures 7-8 , the motor 5-1 is a DC reduction motor. The design of using a DC reduction motor has low vibration, low noise, and can also save energy.

[0035] Preferably: as Figures 7-8 , it further includes a linear bearing 5-9. The linear bearing 5-9 is installed on the second bracket 5-8, and the pull rod 5-4 passes through the linear bearing 5-9; the design of the linear bearing 5-9 can stabilize the pull rod 5-4 to move only in one direction, preventing the pull rod 5-4 from shaking and affecting the service life of the motor.

[0036] Preferably: as Figure 8, which includes a cover plate 5-10. The cover plate 5-10 is installed on the second bracket 5-8 and is used to protect the hinged part at the end of the scissor blade 5-7. The design of the cover plate 5-10 can provide a certain degree of protection for the driving part of the scissor blade 5-7 and prevent foreign objects from being wound in.

[0037] Preferably: As Figure 7 , which includes a compression spring 5-11. The compression spring 5-11 is sleeved on the semi-threaded bolt 5-6 and is used to press the scissor blade 5-7. The compression spring 5-11 can keep the two scissor blades 5-7 in contact with each other, making it easy to cut the medicine bag.

[0038] For the printing and heat-sealing assembly of the intelligent medicine sub-packaging machine described in the present invention, its medicine bag synchronization measurement device 2 is installed between the printer 1 and the heat-sealing assembly 4. When the traction distances of the printer 1 and the heat-sealing assembly 4 for the medicine bag 100 are out of sync, it detects the change in the tightness of the medicine bag 100 between the printer 1 and the heat-sealing assembly 4. The medicine bag synchronization measurement device 2 bends and applies force to the medicine bag 100. When the tightness of the medicine bag 100 changes, the detection unit of the medicine bag synchronization measurement device 2 can detect the corresponding change amount, that is, detect the traction distance difference between the printer 1 and the heat-sealing assembly 4 for the medicine bag 100.
