According to the intelligent medicine cabinet, the vertical screw rod unit of the medicine taking mechanism can control the horizontal screw rod unit to ascend and descend, the horizontal screw rod unit can control the medicine hopper unit to move in the left and right directions, so that the medicine hopper unit can reach any required position in a vertical plane in front of the medicine placing rack, the medicine hopper is close to the medicine placing bin, the risk of breakage caused by multiple falling or high falling of glass-packaged medicines is prevented, the medicine hopper is required to be attached to the medicine placing rack during medicine taking, the medicines are prevented from falling from the space between the medicine hopper and the medicine placing rack, interference with the vertical screw rod is prevented during horizontal movement, the medicine hopper is fixed on an output rotating shaft of a fourth speed reducing motor, the problem is solved ingeniously by rotating the medicine hopper, and the problems of medicine feeding modes and counting are solved well by adopting the matching of a conveying belt and a correlation sensor, when placing the medicine, only need open the cabinet door, with the medicine from the back push can, the medicine of phase is in the front, this time medicine is in the back, easy and simple to handle and can prevent to appear owing to put the unreasonable condition that leads to the phase medicine to appear overdue, this scheme can once only be got according to setting for the order with all medicines through the input or sweep the sign indicating number, it is very convenient to use, is applicable to the hospital and doctorses and nurses and gets medicine and the patient independently gets it filled.
Furthermore, locate medicine holding chamber front end both sides the correlation sensor is located the below that corresponds conveyer, and the purpose of doing so falls one, calculates one, prevents that the medicine from hugging closely and the detection error that leads to, and in addition, the correlation sensor is established at medicine holding chamber front end, can in time feed back, and in time control conveyer belt stops to carry, prevents to go out more medicine.
Further, bagging-off mechanism has included snatching of medicine bag, it is fixed, functions such as strut and translation, the medicine bag snatchs the back, second electric putter upwards is according to establishing the distance roof pressure under PLC controller control, in order to guarantee the height of superiors 'medicine bag, guarantee to snatch the effect, whole bagging-off mechanism's structure is very ingenious, the medicine fill removes to required position after getting it filled, pour into the medicine and lie in below open-ended medicine bag, the user stretches out hand and takes the sack like this, need not one and pick up, when conveniently carrying, the time of getting it filled has significantly reduced, also prevent medicine and the contact of basket of getting it filled, the basket of getting it filled need not touched even the user, greatly reduced get the contaminated probability of medicine basket and medicine.
Further, the medicine fill is that the cross-section is positive tetragonal hourglass hopper-shaped, make things convenient for drawing in of medicine, be equipped with out the medicine hole on the medicine fill leading flank, be equipped with eighth gear motor on the medicine fill leading flank, set firmly the baffle that is used for switching out the medicine hole in eighth gear motor's the output pivot, rotate medicine fill and baffle respectively during the use, just can adjust out the best play medicine position, set up out the medicine hole, the height drop between medicine and the medicine bag has been reduced, further reduce the glass bottle and pouring into the cracked probability of medicine bag, and it compares the little many of port on the medicine fill to go out the medicine hole, pour the medicine into the medicine bag more easily.
Furthermore, a packaging mechanism is arranged, and the medicine bag is subjected to hot melting packaging under the matching of the packaging mechanism, so that medicine pollution is further avoided, and even in a high risk period, a user only needs to disinfect the medicine bag after taking medicine, so that the possibility of epidemic disease propagation is greatly reduced.
Furthermore, a pressure spring is arranged between the two cylinders, and after the first pneumatic sucker and the second pneumatic sucker are separated from the medicine bag, the two cylinders are pushed to move in the left-right direction through elasticity, so that the upper openings of the medicine bag are combined again, and the medicine bag can conveniently enter the packaging mechanism for packaging.
Furthermore, the rear of getting it filled the basket is equipped with the fifth electric putter that will get it filled the basket and release and pull back the cabinet body, is equipped with the ultraviolet ray disinfection lamp on the inner wall of the front panel of the basket top of getting it filled, has made things convenient for the user to get it filled like this, and after the user got it filled, it was internal that the PLC controller will get it filled the basket and pull back the cabinet through fifth electric putter, avoided getting it filled the basket and disinfected the basket of getting it filled through the ultraviolet ray disinfection lamp.
Utilize the method of getting it filled of above-mentioned structure intelligence medicine cabinet, multiple medicine is once got to completion that can be fine, and it is light simple to get it filled, prevents that the bottled medicine of glass is cracked, conveniently places the medicine in medicine holding chamber from the back forward.
Furthermore, the packaging and the packaging are convenient, and the spreading risk of epidemic diseases is reduced.
