Description
Technical field
The present invention relates to a kind of method and system that can automatically detect solid impurity in the bottling liquid.
Background technology
What present various injections, medicament, oral liquid medicine used in a large number is vial or transparent plastic bottle; in order to detect whether sneak into glass particle or other solid impurity in the production run in the liquid pharmaceutical, need carry out impurity to each bottle medicament on the production line and detect.Chinese patent application (number of patent application: 03124859.4, publication number 1529165) a kind of " full-automatic bottling medicament machines " disclosed, this machines is utilized conveying device, advance a bottle screw rod, advance bottle star-wheel bottled medicament is sent into working rotary table, mechanical arm on the working rotary table is picked up it, after soft band friction-driven, the vial retrograde rotation, when vial arrives the check point of being made up of light source generator and Digital Video, scratch diskette is done that moment pauses and is formed vial and stop operating, and the state that the medicament in the bottle is still rotatablely moving, Digital Video is sent image into system software and is analyzed and detect, and substandard product is rejected.There is following shortcoming in this machines:
1, detection speed is slow.When the vial of this machines arrives check point, scratch diskette must pause moment, reach liquid phase rotatablely moving and the stationary state of the relative video camera of vial to vial, so that video camera carries out camera work, all vials all will stop operating with respect to the scratch diskette axle center on the scratch diskette at this moment, treat to rotate again after shooting finishes, in order to reduce the moment of inertia of system again, the velocity of rotation of scratch diskette can not be fast, causes the detection speed of system very slow.
2, system architecture complexity.Scratch diskette moment pause requires the associated transmission system of whole machines all will carry out corresponding pause, and corresponding system architecture is very complicated.
3, the detection quality is low.Scratch diskette moment pause, cause the vial with soft band friction rotation to quicken moment or to slow down, and liquid phase is when rotating to bottle, the asynchronous rotation of liquid and produce bubble before and after unexpected acceleration or deceleration can cause, the existence of bubble can influence the accuracy of detection of system, even produces flase drop.
4, range of application is little.Mechanical arm is because the restriction of structure can only be used for the extracting of common oral liquid bottle, and for ampoule, mechanical arm is difficult to grasp bottle, and for the asparate infusion bottle of 500mL, mechanical arm is difficult to fixedly bottle.
5, detection light source be provided with unreasonable.For columned bottle, the light of simple incident from the side, greatly by diffusion, the light of diffusion enters video camera through after the reflection of other vials, cause the difficulty of systematic analysis.

The principle of the invention:
Tested bottle uniform acceleration starts, at the uniform velocity keeps and the fast braking principle: the bubble that produces when reducing bottle interior liquid in rotation as far as possible, the acceleration of the boost phase of tested bottle rotation should be consistent, at the uniform velocity keep the regular hour then, again fast braking.The rear supporting roller of system of the present invention can be according to the contact pressure edge and belt vertical direction back and forth movement of the belt between two engaged wheels with the friction pulley that enters accelerating region, thereby adjusting belt automatically is constant to the friction force of friction pulley, guarantees that belt starts and keep the uniform rotation in district at the uniform acceleration of accelerating region; The pressure rail of clamping device is arranged in the friction zone, when being the friction pulley contact belt on the clamping head, the roller of driving lever end is pressed rail to compress into inwards, drive the axle surface of the friction disc at passive bar middle part away from friction pulley surface or friction pulley, this moment, friction pulley can be by the belt driven rotary, thereby driving the clamping head that is connected with it rotates, when friction pulley leaves friction zone, pressing rail to stop pair roller exerting pressure, driving lever outwards moves under the effect of compression spring, drive the axle surface of friction disc pressing friction wheel surface or friction pulley, realize the braking fully of clamping head, reenter friction zone until another tested bottle of clamping head clamping, friction disc just unclamps again.Because the present invention can automatically detect ampoule, infusion bottle and the oral liquid bottle of 1mL to 500mL, so quicken rotation is to adopt one-level driving acceleration or multistage driving to quicken, the tested bottle of general capacity adopts one-level to drive and quickens, and the tested bottle of the special capacity of part adopts two-stage drive to quicken; The even acceleration time of the tested bottle of general capacity is 0.5～5 second, and speed setting value is 300～2000 rev/mins, and at the uniform velocity Xuan Zhuan time is 0.5～5 second, and the time of fast braking is 0.02～0.08 second.
The continuous detecting principle of work: the rotary table speed of gyration is regulated by the production line pace, synchronous follow-up device comprise be arranged on the testing platform with the outer one to one shackle member of clamping head and be arranged on an interior shackle member on the camera work platform, interior shackle member on the camera work platform can be periodically flexible, when interior shackle member is stretched out, outer shackle member and the mutual clamping of interior shackle member, thus the testing platform drives the at the uniform velocity revolution synchronously of camera work platform.When clamping device drives tested bottle and arrives camera position, the liquid emission that the light beam that detection light source is sent rotates in bottle also produces diffusion, camera work platform this moment and tested bottle advanced in unison, static relatively, video camera begins the continuous several times shooting, after shooting is finished, interior shackle member withdrawal, the camera work platform returns back to the original position backward under the extension spring effect, until run into next clamping device corresponding outside shackle member, driven once more forward and rotated, the tested bottle of the next one is made a video recording synchronously.In the shooting process, do not need rotary table to do moment and pause, so system of the present invention testing process is the continuous working process.The continuous detecting process of straight line worktable is similar to rotary table.
Go out the bottle principle of work: when the tested bottle of having made a video recording enters out bottle, if it is substandard product that image comparison result shows this bottle, then the analysis and Control module sends a rejecting instruction to going out bottle, go out separation turnover panel in the bottle stirs the specification product travelling belt from the entry position of rejecting the product travelling belt entry position, then the separated turnover panel of this tested bottle blocks, and can only enter to reject the product travelling belt; If specification product, the analysis and Control module is not sent any instruction, and the separation turnover panel retaining that goes out in the bottle is the original position in the entry position of rejecting the product travelling belt, and this tested bottle enters the specification product travelling belt.
