Description

A kind of mechanism that quantitatively gets it filled

Technical field

The present invention relates to a kind of mechanism that quantitatively gets it filled, specifically can limit the people that gets it filled, belong to field of medical according to the quantity of the doctor's advice regulation medicine of taking.

Background technology

Medical industry all can run into the problem of management of numb poison article and costly medicine, generally all is now to adopt cabinet special to add special messenger's rules for storage, the transition issue that resultant personnel's changing shifts causes, and the problems that artificial wrong report is lied about can't solve.

Summary of the invention

The objective of the invention is to overcome above-mentioned weak point, thereby a kind of mechanism that quantitatively gets it filled is provided, be used for management and deposit the special medicine of hospital.

According to technical scheme provided by the invention; A kind of mechanism that quantitatively gets it filled comprises motor, base and drawer; Said motor is fixed on the base, it is characterized in that: also comprise drive screw, revolution counter sensor, blanking disc, anti-dazzling screen, first limiting photoelectric switch, second limiting photoelectric switch and nut, said drive screw is connected on the motor; Blanking disc is positioned on the drive screw, and the revolution counter sensor is fixed on the blanking disc top; Said first limiting photoelectric switch is positioned at drive screw left end below, and second limiting photoelectric switch is positioned at drive screw right-hand member below; Said drawer is positioned at the drive screw top, is connected with drive screw through the nut below the drawer.

Said drive screw is connected the motor right-hand member through being coupling; Said nut is welded on the drawer lower surface, and nut and drive screw are through being threaded; Said nut lower end is connected with anti-dazzling screen; Be provided with at least one dividing plate in the said drawer; Be provided with sealing baffle around the said drawer.

Compared with present technology the present invention has the following advantages:

The present invention is simple, compact and reasonable for structure; Operating personnel are carried out identification and the process of getting it filled is controlled through computer, having stopped the people is mistake and the leak that causes, and really realizes the control of quantitatively getting it filled of overall process, with other control medicines the hardware assurance is provided for using numb poison article safely.

The specific embodiment

Following the present invention will combine the embodiment in the accompanying drawing to further describe:

The present invention mainly comprises motor 1, base 2 anddrawer 11; Said motor 1 is fixed on the base 2; Also comprise drive screw 7, revolution counter sensor 5, blanking disc 6, anti-dazzling screen 8, first limiting photoelectric switch 3, second limiting photoelectric switch 10 and nut 9; Said drive screw 6 is connected on the motor 1, and blanking disc 6 is positioned on the drive screw 7, and revolution counter sensor 5 is fixed on blanking disc 6 tops; Said first limiting photoelectric switch 3 is positioned at drive screw 6 left ends below, and second limiting photoelectric switch 10 is positioned at drive screw 7 right-hand members below; Saiddrawer 11 is positioned at drive screw 7 tops, and the nut 9 throughdrawer 11 belows is connected with drive screw 7.

Said drive screw 74 is connected the motor right-hand member through being coupling; Said nut 9 is welded ondrawer 11 lower surfaces, and nut 9 and drive screw 7 are through being threaded; Said nut 9 lower ends are connected with anti-dazzling screen 8; Be provided with at least one dividing plate 11-1 in the saiddrawer 11; Be provided with sealingbaffle 12 around the saiddrawer 11.

Operation principle of the present invention:

Saiddrawer 11 is used to deposit medicine, through dividing plate 11-1drawer 11 is divided at least two little lattice, deposits the medicine of a unit in each little lattice.Withbaffle plate 12 sealings, the opening and closing ofdrawer 11 are controlled by computer around thedrawer 11, and the people that gets it filled can't open drawer.When getting it filled, motor 1 drives the nut 9 that drive screw 7 rotates and drive screw 7 links together that is coupling together and receives screw thread torsion and move right, and nut 9drives drawer 11 again moves right, anddrawer 11 is opened; If motor 1 counter-rotating, thendrawer 11 is to left movement,drawer 11 closures.The blanking disc 6 that is positioned on the drive screw 7 is driven by drive screw 7; Drive screw 7 rotates a circle; Blanking disc 6 just rotates a circle; The revolution counter sensor 5 that is positioned at blanking disc 6 tops just records a signal, then signal is passed to the control computer, and motor 1 stops operating when the length ofdrawer 11 unlatchings reaches necessary requirement.Whendrawer 11 arrived the left end extreme position, the anti-dazzling screen 8 of nut 9 belows covered the light source of first limiting photoelectric switch 3, and first limiting photoelectric switch 3 is transmitted signal and given computer, and computer control motor 1 stops operating, anddrawer 11 is with regard to stop motion; Whendrawer 11 arrived extreme right position, the anti-dazzling screen 8 of nut 9 belows covered the light source of second limiting photoelectric switch 10, and the secondth limiting photoelectric switch 10 is transmitted signal and given computer, and computer control motor 1 stops operating, anddrawer 11 is with regard to stop motion.
