Description

Technical Field

[0001] The invention relates to the technical field of western medicine packaging machines, and in particular to a medicine box feeding mechanism for a chronic disease management system. Background Art

[0002] The existing western medicine packaging machine preheats the PVC coil during the flat transmission process, and then uses a mold and vacuum to suck the mold to shape it. After shaping, the machine puts the medicine in, then transmits it to the film sealing mechanism for sealing, and finally transmits it to the shearing mechanism for cutting.

[0003] This type of packaging machine is only suitable for packaging large quantities of the same type of drugs. In most cases, hospitals use whole packages or bottles of drugs for patients. Excessive drugs need to be manually packaged and distributed to patients in advance. This method has four defects. The first is that it occupies a large number of medical personnel for packaging work; the second is that manual packaging is inevitably prone to errors due to external environmental influences or personal reasons. When the drug is packaged incorrectly or the dosage exceeds the standard, it may even put the patient's life in danger; the third is that it is not easy to see whether the elderly take the medicine on time when using medicine bags or sealed bags, because it is difficult to distinguish multiple drugs together, and the elderly are prone to forgetfulness; the fourth is that when multiple granules of drugs are loaded into a sealed bag together, other drugs that are not taken temporarily will also be exposed to air and moisture when the bag is opened, affecting the efficacy of the drug.

[0004] In order to solve the above problems, our company invented a drug packaging machine for chronic disease management system, and the feeding mechanism is an indispensable part of the packaging machine. Summary of the invention

Specific implementation method 1

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the illustrative embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention.

[0027] like Figure 1As shown, a medicine box feeding mechanism for a chronic disease management system described in this specific embodiment includes a frame 1, a pallet lifting motor 2, a lifting belt 3, a medicine box lifting screw 4, a medicine box lifting screw slider 5, a medicine box pallet 6, a reciprocating motor 7, a driving wheel 8, a passive wheel 9, a reciprocating belt 10 and two fork medicine box devices 11; the pallet lifting motor 2, the medicine box lifting screw 4, the reciprocating motor 7, the driving wheel 8 and the passive wheel 9 are all installed on the frame 1; the medicine box pallet 6 is installed on the medicine box lifting screw slider 5, and the pallet lifting motor 2 drives the screw of the medicine box lifting screw 4 through the lifting belt 3 Rotation causes the medicine box lifting screw slider 5 to drive the medicine box support plate 6 to reciprocate up and down; the driving wheel 8 and the passive wheel 9 are distributed on both sides of the medicine box lifting screw 4, and the reciprocating motor 7 drives the driving wheel 8 and the passive wheel 9 to rotate; the two fork medicine box devices 11 are symmetrically distributed on both sides of the medicine box lifting screw 4, one fork medicine box device 11 is connected and fixed to the upper belt of the reciprocating belt 10, and the other fork medicine box device 11 is connected and fixed to the lower belt of the reciprocating belt 10, so that when the reciprocating motor 7 rotates forward, the two fork medicine box devices 11 move together synchronously, and when the reciprocating motor 7 rotates reversely, the two fork medicine box devices 11 move away from each other synchronously.

[0028] Combination Figure 1 , 2 / 5 and 6, the whole page of medicine boxes 13 falls onto the medicine box support plate 6 under the transmission of the medicine box conveying device 12, and the support plate lifting motor 2 drives the lifting belt 3 to rotate, thereby driving 4, the medicine box lifting screw slider 5 and the medicine box support plate 6 to lift the medicine box 13, and the travel distance is controlled by the microcomputer controller to control the rotation distance of the support plate lifting motor 2. When the medicine box support plate 6 rises to the set position, it stops rising; then the reciprocating motor 7 operates according to the program set by the microcomputer controller, at this time, the reciprocating belt 10 drives the two fork medicine box devices 11 to move closer to the middle, and the medicine box 13 sent up by the medicine box support plate 6 is received, and it is handed over to an external manipulator for transportation to the heat sealing mechanism. At the same time, the support plate lifting motor 2 rotates in the opposite direction under the setting of the microcomputer controller to restore the medicine box support plate 6 to Figure 5 The medicine box conveying device 12 conveys the medicine box forward one station; during the descent of the medicine box support plate 6, the external manipulator takes over the medicine box clamped by the two fork medicine box devices 11, and the microcomputer controller controls the reciprocating motor 7 to rotate in the opposite direction, and opens the two fork medicine box devices 11 again, so that the above actions can be repeated to complete the uninterrupted medicine box feeding work.

[0029] Since the medicine box conveying device 12 is not the part protected by this application, and this kind of stepping conveyor belt is very common in industry and is easy to control, it will not be introduced in detail again. The direct cooperation of a series of motors in this application is controlled by a microcomputer controller. This control method is easy to implement under the current intelligent control technology conditions, and the company has applied for the corresponding software copyright for this control program, so it will not be described in detail here. Only the pure mechanical part that this application requires to be protected is introduced in detail.

[0030] The fork medicine box device 11 here does not have strict requirements. It only needs an F-shaped or E-shaped component, one end of which can be fixed on the reciprocating belt 10 and the other end can hold up the medicine box 13. The medicine box itself is very light, and no special requirements are made on the structure of the fork medicine box device 11.

[0031] Preferably, the lifting belt 3 is a synchronous belt; the setting of the synchronous belt ensures that there is almost no slippage between the pallet lifting motor 2 and the lifting belt 3, which is conducive to controlling the rising accuracy of the medicine box pallet 6.

[0032] Preferably, the reciprocating belt 10 is a synchronous belt. The setting of the synchronous belt ensures that there is almost no slippage between the reciprocating motor 7 and the reciprocating belt 10, which is conducive to controlling the travel distance of the two fork medicine box devices 11.

[0033] Preferably, the pallet lifting motor 2 and the reciprocating motor 7 are stepping motors; stepping motors are conducive to controlling the travel accuracy by a microcomputer controller. Specific implementation method 2

[0035] like Figure 3 and 4As shown: In this embodiment, the fork medicine box device 11 is upgraded and improved, and the fork medicine box device 11 includes a fork frame lifting motor 11-1, a gear pair 11-2, a lifting frame 11-3, a fork frame lifting screw 11-4, a fork frame lifting slider 11-6, and a fork frame 11-7; the fork frame lifting motor 11-1 and the fork frame lifting screw 11-4 are installed on the lifting frame 11-3; the two gears of the gear pair are respectively installed on the lifting motor 11-1 and the fork frame lifting screw 11-4 The screw rod, the lifting motor 11-1 reciprocates, and the gear pair 11-2 pushes the fork frame lifting screw 11-4 to reciprocate up and down; the fork frame lifting slider 11-6 is installed on the fork frame lifting screw The top of the screw rod of the lever 11-4; the fork frame 11-7 is installed on the fork frame lifting slider 11-6; this design ensures that when multiple medicine boxes 13 are stacked, the medicine box support plate 6 can transport multiple medicine boxes at the same time, and the height of the fork frame 11-7 can be raised and lowered by the reciprocating motion of the fork frame lifting motor 11-1, and multiple medicine boxes can be taken out each time for multiple times. After taking each medicine box, the medicine box support plate 6 only needs to drive the remaining small amount of downward movement to make room for the operation of the external manipulator. This kind of microcomputer controller controls multiple stepper motors in coordination with each other, which can also be achieved by simple programming. Since our company has also applied for the corresponding software copyright, we will not go into details here.

[0036] At this time, the reciprocating belt 10 can be connected and fixed to one side of the lifting frame 11-3. Specific implementation method 3

[0038] like Figure 3 and 4As shown: This specific implementation is an improvement on the basis of implementation mode 2, and it also includes a travel switch 11-5 and a rotating shaft 11-8; the travel switch 11-5 is installed on the fork frame lifting slider 11-6; the fork frame 11-7 is hinged between the rotating shaft 11-8 and the fork frame lifting slider 11-6, and the bottom of the fork frame 11-7 under its own weight is against the travel switch 11-5 to close the travel switch 11-5, and when the fork frame 11-7 is lifted by the medicine box 13, the fork frame 11-7 rotates around the rotating shaft 11-8, and the bottom of the fork frame 11-7 is away from the travel switch 11-5, so that the travel switch 11-5 is opened. The travel switch 11-5 is designed to accurately control the lifting height of the medicine box 13. When multiple medicine boxes are transported at the same time, the rising height of the medicine box support plate 6 after taking away a medicine box needs to be set in the microcomputer controller to ensure that the support plate lifting motor 2 rises to the right position each time. After the travel switch 11-5 is set, no matter how many medicine boxes 13 are on the medicine box support plate 6, as long as the top medicine box hits the fork frame 11-7, the fork frame 11-7 can rotate around the shaft 11-8, and the shaft 11-8 leaves the travel switch. After the travel switch 11-5 reflects the signal to the microcomputer controller, the microcomputer controller controls the pallet lifting motor 2 to rotate in the opposite direction, the medicine box 13 descends, the fork frame 11-7 rotates in the opposite direction around the rotating shaft 11-8, and the fork frame 11-7 resets. At this time, the travel switch 11-5 is reconnected, and the travel switch 11-5 feeds back the signal to the microcomputer controller. At this time, the microcomputer controller can stop the rotation of the pallet lifting motor 2, and at the same time control the reciprocating motor 7 to drive the fork frame 11-7 to fork the medicine box 13. Since our company has applied for the corresponding software copyright for the above control program, we will not repeat it in detail again.

[0039] Preferably, the fork frame lifting motor 11-1 is a stepping motor, and the design of the stepping motor ensures that the up and down movement accuracy of the fork frame 11-7 can be easily controlled.

[0040] As a preferred embodiment, it also includes a proximity switch 11-9, which is installed on the lifting frame 11-3 and is used to detect whether the fork frame lifting slider 11-6 is in place. When the proximity switch senses that the fork frame lifting slider 11-6 is in place, it will send a signal to the microcomputer controller, and the microcomputer controller will match the set signal, and only after the match will the next step of reciprocating motor 7 operation be performed. Since the company has applied for the corresponding software copyright for the above control program, it will not be described in detail again.

[0041] Preferably, it further comprises a slide rail 11-10, the slideway of the slide rail 11-10 is mounted on the lifting frame 11-3, and the guide rail of the slide rail 11-10 is used to be mounted on the frame 1, and is used to limit the reciprocating belt 10 from driving the fork medicine box device 11 to move in the horizontal direction. The design of the slide rail 11-10 only affects the fork medicine box device 11 from moving up and down, and the left and right directions of the approaching and separating are still driven by the reciprocating belt 10, and the connection method can be kept the same as that in the specific embodiment 2.

[0042] After adopting the above structure, the beneficial effects of the present invention are as follows: the medicine box feeding mechanism for a chronic disease management system described in the present invention adopts a medicine box support plate design driven by a screw, which can transfer the medicine box of a single plate from the conveyor belt to the fork medicine box device, and the fork medicine box device picks it up and hands it over to the medication device, providing essential key support for the medicine dispenser of the chronic disease management system, and is an indispensable part of the medicine dispenser of the chronic disease management system.

[0043] This mechanism can transfer the medicine boxes of a single plate, providing support for the manufacture of medicine dispensing machines for chronic disease management systems by eliminating the need for PVC coil heating mechanisms, mold suction mechanisms, and shearing mechanisms.

[0044] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
