It is helically wound around in example accompanying drawing for a driving wheel 5, thin diameter section 11 on driving wheel 5, it is ensured that select the stability of pearl bar 1.Certainly it is thick
Driving wheel 5 is may also set up in footpath section 12.
In pearl screening process, because wide section 12 or pearl endoporus are not clean smooth enough, pearl is surprisingly stuck in wide section
On 12, cause pearl be accumulate to thickness footpath combination screening at, the first detector 31 will be reported by mistake, photos and sending messages to control device,
So that the pearl at the broken screening point of the continuous uninterrupted mistakenly hit of Sui Zhu mechanisms 2, therefore as optimization, testing agency also includes setting
Be placed in select on the wide section 12 of pearl bar 1 or particle size screening point under the 3rd detector 33.
Wherein, first, second, third detector 31,32,33 is both preferably one, and one detectable to select on pearl bar 1 one
The pearl of point position, detects that signal persistently transmits the corresponding time and is used as separation by the point, realizes corresponding control information
Switching.And multiple detectors can be used to detect the one section of pearl selected on pearl bar 1, the upper and lower test point of one section of pearl is used as switching
The separation for transmitting different information realizes the switching of corresponding control information.
First, second, third detector 31,32,33 includes the stroke device 34 for pressing close to select pearl bar 1 to monitor pearl and detection row
The stroke inductor 35 of the location status of journey device 34.Preferably, detector may include to press close to the runner 36 of the contact of stroke device 34,
Pearl bar 1 is selected to be held between the contact of stroke device 34 and runner 36, the circumference of the one or both ends of runner 36 is provided with can jack-up stroke
The projection 37 of the contact of device 34, projection 37 is provided with gap with pearl in the axial direction, not influence the activity of pearl.Projection 37 can
Make the regular swing of stroke device 34, prevent stroke device 34 because unexpected situation is cohesive and slow in reacting.Stroke device 34 can be inspection
Resetting sliding block or can resetting in swing rod, the implementation case by taking swing rod as an example for position signalling is surveyed, stroke device 34 can be answered including one
Position swing rod 34a, be arranged at the arcuation projection 36a that coordinates swing rod 34a on runner 36 as contact, swing rod 34a ends provided with
The convex tail 34b that inductor 35 coordinates.In order to more accurate sensitive detection pearl.
With reference to the use of present device, the inventive method is further explained.
Pearl equipment is selected in startup, and beading mechanism 4 starts a beading and the string for the thin diameter section 11 for selecting pearl bar 1 is delivered to by output end
Pearl one end, continues to convey composition bead string, mobile pearl can stir the swing rod 34a of the stroke device 34 of the second detector 32 first,
Make its swing accomplished continuously or intermittently, stroke inductor 35 is by the signal transmission detected to control device, and this kind of signal is preset
The signal of the normal work of beading mechanism 4 is judged for control device.If the pearl accumulation bunchiness on thin diameter section 11, and highly exceed
The test position point of second detector 32 of the top of thin diameter section 11, the then bead string constituted persistently pushes up the swing rod 34a for starting journey device 34, OK
Journey inductor 35 continues to transmit this kind of signal for a period of time accordingly, then control device judges not needing a beading, will suspend a beading
The beading of mechanism 4, until the bead string on thin diameter section 11 is consumed to the test position point less than the second detector 32.Treat the second detector
The 32 swing rod 34a of stroke device 34 continues or done only on runner 36 under arcuation projection 36a driving regular swing, stroke sensing
Device 35 transmits this kind of signal, then control device judges to need a beading, starts beading mechanism 4 and continues a beading until pearl is accumulated again
More than the position of the second inductor 34.
Pearl further convey it is descending, can be delivered to reference to driving wheel 5 thickness footpath junction screening, internal orifice dimension meet require
Pearl then continued traveling downwardly by thickness footpath junction to discharge and select pearl bar 1.The underproof pearl of internal orifice dimension can be then stagnated in thick
Thin footpath junction, follow-up pearl can then be forced to stagnate accumulation.The Cleaning Principle of first detector 31 can be with the second detector 32
Principle, i.e. normal signal, Sui Zhu mechanisms 2 do not work.When the swing rod 34a of the stroke device 34 of the first detector 31 continues to be opened by top
For a period of time, the stroke inductor 35 of the detector 31, by the signal transmission to control device, control device then judges internal orifice dimension
Underproof pearl is stagnated in thickness footpath junction, and drives the action of Sui Zhu mechanisms 2 to smash the underproof pearl.Follow-up pearl
Son will continue through screening point, wait to be screened, filter out the qualified pearl of internal orifice dimension.
The Cleaning Principle of 3rd detector 33 is with first, second detector concept.During work, i.e., when the pearl on wide section 12
Normal through wide section and pass, the 3rd detector 33 is operating normally, control device judges that no pearl is trapped in wide section 12
On.There is pearl to block stop when the 3rd detector 33 does not detect the corresponding position of wide section 12, and only the first detector
31 when detecting pearl not by the screening point of thickness footpath junction, and control device can just drive Sui Zhu mechanisms 2 to smash internal orifice dimension
Real underproof pearl;Otherwise the firstth, the 3rd detector 31,33 detects to select respectively the corresponding position of pearl bar 1 have pearl stagnation, control
Device processed will not then drive the mistakenly hit screening point pearl of Sui Zhu mechanisms 2, until the pearl on wide section 12 normally passes beading bar.
