Under when regarding among the present invention the work of medicine packaging facilities bag medicine speed describe.
Length is generally between 1.2~1.6 meters in the medicament collection channel of legacy equipment, and relying on gravity is that the medicament of propulsion source falls in collection channel will be according to the free-falling body rule, and its shared time is:
Ts
2=2h/g
Wherein g is gravity acceleration value, and h is the height of medicament collection channel.In design, in order to guarantee reliability, the h value is the maximum height 1.6m of passage, the medicament lowering time Ts that draws thus
1Be about 0.57 second.
On the other hand, medicament has been accumulated kinetic energy when falling in collection channel, falling collection channel when bottom at medicament, generally is kinetic energy to be discharged through bouncing several times, and system need to wait that medicament is static to get off, just can be transported to next link, therefore, in this process, the energy drop away time of system arrangement medicament, namely so-called " bounce time " represents with Tp.Because this energy discharge is pressed Normal probability distribution, therefore, Tp can be expressed as:
Tp=P(N)
Wherein N is the kinetic energy that medicament has when dropping to the bottom Contact in collection channel, and according to free fall law, the height h before this kinetic energy and medicament fall is linear relationship, and therefore, Tp can also be expressed as:
Tp=P’(h)
In a large amount of statistical tests and practical application in industry, all show, in the situation that height h is 1.6m, bounce time Tp
2Value be about 0.33 second, although other flow process and action in the equipment work also occupy the regular hour separately, but, these other flow processs or move shared time or be very short (being designated as Tn) even negligible (time, medicament feeder drug time, the device for trapping of giving an order such as system stir time etc.), be to overlap (such as information printing, heat seal envelope, output etc.) of finishing in the time period of collecting flow process, finishing a used maximum duration of flow process action in the legacy equipment can be expressed as:
Ts
1+ Tp
1+ Tn=0.57+0.33+0.09=0.99 second
Wherein the Tn value is 0.09 second, and this time is the summation that time, medicament feeder drug time, device for trapping that system gives an order stir time etc.
In sum, legacy equipment can allow each flow process finish separately action within 1.0 second time, and therefore, the overall bag medicine of legacy equipment is fastest to be about per minute 60 bags.
, being kinetic energy section drop away time of medicament, total time is limited in about 1s.In addition, the drug action all can be controlled in the 1s, and the required action of other flow processs all can not surpass 0.1s, can realize very soon.
Realized the repeatedly collection of medicament in the technical scheme of medicine packaging facilities of the present invention by device for trapping 113, actv. has shortened collection channel.Two layers of structure that supplies medicine assembled unit 11 are set as example take medicine storage cabinet 1, the maximum height of the free-falling body of medicament is about 1/3rd of prior art, namely is no more than 0.5m, brings formula Ts into
2=2h/g and formula draw Ts
2Be 0.32 second, " bounce time " Tp=P ' (h) draws Tp for being approximately linear (this conclusion is verified as accurately by experiment test) under identical variance in 0.1~2.0 meter scope
2Be 0.1 second, finishing a used maximum duration of flow process action in the new installation of the present invention can be expressed as:
Ts
2+ Tp
2+ Tn=0.32+0.1+0.09=0.51 second
Wherein the Tn value still is 0.09 second, and this time is the summation that time, medicament feeder drug time, device for trapping that system gives an order stir time etc.
In sum, new installation of the present invention can allow each flow process finish separately action within 0.51 second time, and therefore, the overall bag medicine of new installation of the present invention is fastest to be reached about per minute 120 bags., be 2 times of bag medicine speed of the prior art.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
