A method for detecting the impurity (broken glass) in the bottle of powder injection is characterized by that said bottle is vibrated and the collision wave between impurity and bottle is sensed. Its apparatus is composed of bottle holder, vibration generator, collision sensor and signal processor. Its advantages are simple structure and high correctness.
Description
Technical field: the present invention relates to a kind of detect the method that whether has residual quarrels such as cullet in the medical powder injection bottle and this method special-purpose pick-up unit.
Background technology: medical powder injection is when carrying out operations such as medicine bottle cleaning, sterilization, drying, medicinal powder can, sealing, because the phenomenon that collide mutually between bottle and the bottle, the vial fragmentation can appear in extruding, broken quarrel enters in the medicine bottle sometimes, though have special operation can remove the broken quarrel of exhausted major part, still also can have broken quarrel in indivedual bottles.Because the production of powder-injection is carried out with pipelining technique, output is very big, how to detect whether have a great problem that broken quarrel becomes puzzlement manufacturer in the medical vials.Some units attempted multiple detection method at the problems referred to above, as: adopt optical method, Weighing method.Optical method is because the medicinal powder in the bottle and the effect of vial wall are difficult to prove effective, and the weight method false drop rate is high, thereby is difficult to carry out.And still do not have at present a kind of device that is used to detect powder pin foreign matter in bottles.
Summary of the invention: the detection method and the pick-up unit that the invention provides a kind of impurity in medical powder injection bottle.This method has solved the false drop rate height of existing detection method existence, the problem of detection weak effect, and this pick-up unit is suitable for automated production, has simple in structure, advantage of high production efficiency.Detection method of the present invention is: medicine bottle is applied vibration, and with broken quarrel in the sensor bottle and the percussion wave that bottle wall bump produces, detect the medicine bottle that shock wave is arranged, be the medicine bottle that has broken quarrel.The optimum frequency that medicine bottle is applied vibration is 1～20Hz, and best amplitude is 0.5～10cm.Used sensor is vibration transducer or acceleration transducer.Aborning, size through the foreign matters such as cullet in the medicine bottle after the special operation removing is not very little, when the medicine bottle to-and-fro movement, behind the bottle wall bump of cullet and medicine bottle, can produce shock wave, can detect this impact with sensor, whether according to signal of sensor, can judge has the broken quarrel of glass to exist in the bottle.Pick-up unit of the present invention comprises a clamper 1 that medicine bottle is clamped and unclamp, applies the vibration machine 2 of vibration to clamper 1, also comprise the sensor 3 that broken quarrel is impacted in the induction medicine bottle, the signal processor 4 that is connected with sensor 3, sensor 3 is installed on the clamper 1.At first medicine bottle is clamped during use with clamper 1; Make clamper 1 produce vibration with vibration machine 2 again, whether the impact of broken quarrel is arranged in the sensor 3 induction medicine bottles simultaneously; Sensor 3 is passed to signal processor 4 with signal, and signal processor 4 is with after the signal Processing, and whether show has the broken quarrel of glass to exist in the medicine bottle; Last clamper 1 unclamps, and detected medicine bottle is put down.Pick-up unit of the present invention is simple in structure, easy to operate, be suitable for automated production, efficient height.Method of the present invention can medicine bottle clean and sterilization after any station carry out, can be arranged in outside the desinfection chamber for existing production line, carry out before the packing, have conveniently, flexibly, accuracy rate is high, detect good effectiveness.
