Returning to the initial state.

And (3) charging and mounting:

Opening a cover plate of a medicine bag box, orderly placing a certain number of continuous medicine bags into the medicine bag box, taking out one end of the continuous medicine bags, opening a front cover of a medicine bag taking machine, placing one end of the continuous medicine bags on a conveying device of the medicine bag taking machine, enabling an upper conveying belt and a lower conveying belt of the medicine bag taking machine to clamp the medicine bags (note that the end heads of the medicine bags cannot exceed the conveying device so as to prevent a correlation counting device of a shearing device), covering the front cover of the medicine bag taking machine, assembling the medicine bag taking machine and the medicine bag box, covering a medicine bag box cover plate (mounting the assembled medicine cabinet of a continuous medicine bag discharging unit onto a designated position of a rack, pushing the medicine cabinet of the continuous medicine bag discharging unit into the designated position to enable the medicine cabinet of the continuous medicine bag discharging unit to be successfully butted with a connector of a socket lock box), and finishing the medicine filling and mounting work.

The working process comprises the following steps:

1. The medicine taking process includes that after a unit medicine cabinet control board receives a medicine picking instruction sent by an upper system, a medicine outlet door motor is controlled by a unit medicine cabinet control board driving program to reversely rotate to open the medicine outlet door, when the medicine outlet door is completely opened and a baffle plate 1 of a motor connecting piece is inserted into a correlation sensor, the medicine outlet door motor stops rotating, and the medicine outlet door is kept in a completely opened state, meanwhile, a conveying belt motor is controlled by the unit medicine cabinet control board driving program to start working, the conveying belt motor drives a gear set to drive an upper conveying belt and a lower conveying belt to synchronously act, medicine bags are smoothly and uniformly sent to a shearing device, the correlation sensor on the shearing device counts the medicine bags passing through the shearing opening, and after the count reaches the medicine bag number of the medicine picking instruction, the conveying device stops working and waits for the shearing device to shear the medicine bags.

2. And (3) shearing and discharging medicines, namely after the unit medicine cabinet control board receives a medicine discharging instruction sent by the upper system, controlling the shearing device motor to start working by the unit medicine cabinet control board driving program, driving the rotating board to rotate clockwise by the shearing device motor, pressing the pressing rod downwards by the deflector rod on the rotating board, simultaneously driving the pressing plate to downwards press, and gradually pressing the cut position of the medicine bag. When the rotary plate deflector rod presses the pressure lever to contact the pressure lever buckle inclined plane 1, the pressure lever buckle is pushed to move backwards along with the downward sliding of the pressure lever on the pressure lever buckle inclined plane 1, when the pressure lever is pressed to the pressure lever buckle vertical plane 1 below the pressure lever buckle inclined plane 1, the rotary plate just rotates to the pressure lever buckle vertical plane 2, the pressure lever just moves downwards to be separated from the pressure lever buckle vertical plane 1 along with the rotary plate deflector rod rotating to the bottom, and at the moment, the pressure lever buckle also moves back to the innermost position. When the rotating plate shifting lever presses the pressure lever to the bottom, the rotating plate shifting lever also enters the tool apron clamping groove, but at the moment, the pressure lever buckle is propped by the rotating plate and does not clamp the pressure lever yet. As the rotating plate continues to rotate from the bottom, the rotating plate enters the pressure bar buckling inclined surface 2, at this time, the pressure bar buckling gradually stretches to the upper surface of the pressure bar along with the sliding of the rotating plate on the pressure bar buckling inclined surface 2 under the thrust action of the spring, and the pressure bar is clamped. In order to prevent the pressing rod from moving upwards along with the rotation of the rotating plate shifting lever, the section of the rotating plate shifting lever, which presses the pressing rod, is provided with a raised eccentric cylindrical section so as to ensure that the rotating plate can continuously press the pressing rod at a stable height in the rotating sliding process of the inclined plane 2 of the pressing rod buckle, thereby ensuring that the pressing rod buckle can extend to the upper edge of the pressing rod completely, pressing the pressing rod, preventing the rotating plate shifting lever from moving backwards along with the rotation of the rotating plate after leaving the pressing rod, and keeping the pressing plate to have continuous and stable pressure on the medicine bag incision so as to ensure the success of cutting the medicine bag. Then, the rotating plate deflector rod drives the knife holder to move upwards, so that the knife blade shears the medicine bag, after the medicine bag is sheared, the knife holder also moves to a position touching the limit switch, and when the knife holder touches the limit switch, the unit medicine cabinet control panel controls the motor of the shearing device to rotate anticlockwise. The motor of the shearing device drives the rotating plate to reversely rotate, the rotating plate deflector rod drives the tool apron to move downwards, and the rotating plate deflector rod withdraws from the tool apron clamping groove after the tool apron returns to the bottom. When the rotating plate rotates anticlockwise to contact with the inclined plane 2 of the pressing rod buckle, the pressing rod buckle starts to push the pressing rod buckle to retreat to separate from the pressing rod, and when the rotating plate rotates to the bottom, the rotating plate slides to the vertical plane 2 of the pressing rod buckle, and the pressing rod buckle is pushed to separate from the pressing rod completely. When the rotating plate rotates to the bottom, the rotating plate deflector rod enters the pressure rod clamping groove, and the rotating plate deflector rod drives the pressure rod to move upwards along with the continuous anticlockwise rotation of the rotating plate, and meanwhile drives the pressure plate to move upwards. When the pressing plate moves upwards, the pressed medicine bag is loosened, and the cut medicine bag falls into the medicine tray below by self weight. Thus, the medicine is sheared out once. Then, the unit medicine cabinet control panel driving program controls the medicine outlet door motor to rotate forwards to close the medicine outlet door, when the medicine outlet door is completely closed and the baffle plate 2 of the motor connecting piece is inserted into the correlation sensor, the medicine outlet door motor stops rotating, and the medicine outlet door is kept in a closed state and waits for taking out medicine next time.

6. A control method for the medicine bag dispensing machine according to any one of claims 1 to 5, characterized in that it comprises the following steps:

1. Picking medicine: When the unit medicine cabinet control board receives the medicine picking instruction sent by the superior system, the unit medicine cabinet control board driver controls the medicine dispensing door motor to rotate in the opposite direction to open the medicine dispensing door. When the medicine dispensing door is fully opened and the baffle 1 of the motor connector is inserted into the through-shooting sensor, the medicine dispensing door motor stops rotating and the medicine dispensing door remains fully open. At the same time, the unit medicine cabinet control board driver controls the conveyor belt motor to start working, and the conveyor belt motor drives the gear set to drive the upper and lower conveyor belts to move synchronously, and the medicine bags are sent to the shearing device evenly and smoothly. The through-shooting sensor on the shearing device counts the medicine bags passing through the shearing port. When the count reaches the number of medicine bags in the medicine picking instruction, the conveyor device stops working and waits for the shearing device to cut the medicine bags and take out the medicine.

2. Cutting out medicine: When the unit medicine cabinet control panel receives the medicine dispensing instruction sent by the superior system, the unit medicine cabinet control panel driver controls the shearing device motor to start working, and the shearing device motor drives the rotating plate to rotate clockwise. The lever on the rotating plate presses the pressure rod downward, and at the same time drives the pressure plate downward, gradually tightening the incision position of the medicine bag. When the rotating plate lever presses the pressure rod to contact the pressure rod buckle inclined surface 1, as the pressure rod slides downward on the pressure rod buckle inclined surface 1, the pressure rod buckle moves backward. When the pressure rod is pressed to the pressure rod buckle vertical surface 1 below the pressure rod buckle inclined surface 1, the rotating plate just rotates to the pressure rod buckle vertical surface 2. As the rotating plate lever rotates to the bottom, the pressure rod just moves down and disengages from the pressure rod buckle vertical surface 1. The rotating plate rotates to the middle of the pressure rod buckle vertical surface 2. At this time, the pressure rod buckle also retreats to the innermost position. When the turn plate lever presses the pressure bar to the bottom, the turn plate lever also enters the knife seat slot, but at this time, the pressure bar buckle is held by the turn plate and has not yet clamped the pressure bar. As the turn plate continues to rotate from the bottom, the turn plate enters the pressure bar buckle inclined surface 2. At this time, the pressure bar buckle gradually extends to the top of the pressure bar under the thrust of the spring as the turn plate slides on the pressure bar buckle inclined surface 2, clamping the pressure bar. In order to prevent the pressure bar from moving upward with the rotation of the turn plate lever, the section of the turn plate lever that presses the pressure bar is provided with a raised eccentric cylindrical section to ensure that the turn plate will continue to press the pressure bar at a stable height during the rotation and sliding of the pressure bar buckle inclined surface 2, thereby ensuring that the pressure bar buckle can fully extend to the top of the pressure bar, press the pressure bar, and prevent the turn plate lever from leaving the pressure bar as the turn plate rotates and the pressure bar moves back, thereby maintaining a continuous and stable pressure on the medicine bag incision to ensure the success of the medicine bag shearing. Then, the rotating plate lever drives the knife holder to move upward, so that the blade cuts the medicine bag. After the medicine bag is cut, the knife holder also moves to the position of touching the limit switch. When the knife holder touches the limit switch, the unit medicine cabinet control panel controls the shearing device motor to rotate counterclockwise. The shearing device motor drives the rotating plate to rotate in the opposite direction, and the rotating plate lever drives the knife holder to move downward. When the knife holder returns to the bottom, the rotating plate lever exits the knife holder slot. When the rotating plate rotates counterclockwise to contact the inclined surface 2 of the pressure bar buckle, it starts to push the pressure bar buckle backward and retreat from the pressure bar, until the rotating plate rotates to the bottom, the rotating plate slides to the vertical surface 2 of the pressure bar buckle, and the pressure bar buckle is completely pushed away from the pressure bar. When the rotating plate rotates to the bottom, the rotating plate lever enters the pressure bar slot. As the rotating plate continues to rotate counterclockwise, the rotating plate lever drives the pressure bar to move upward, and at the same time drives the pressure plate to move upward. When the pressure plate touches the upper limit switch, the motor stops working, completing a complete shearing movement. When the pressing plate moves upward, the compressed medicine bag is released, and the cut medicine bag falls into the medicine tray below by its own weight. At this point, one cutting and discharging of medicine is completed. Then, the unit medicine cabinet control board driver controls the medicine discharging door motor to rotate forward to close the medicine discharging door. When the medicine discharging door is completely closed and the baffle 2 of the motor connector is inserted into the cross-shooting sensor, the medicine discharging door motor stops rotating, and the medicine discharging door remains closed, waiting for the next medicine to be taken out.
