Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail.
The inventive method relate to fall bottle and Cancellation Missed detection device install reflective photoelectric switch as sensor,
Often the set detection of falling bottle device uses two same model photoswitches arranged vertically, and one, top photoswitch is swept
Retouching bottleneck and go up most edge, following photoswitch scanning body, scanning height is equal to body radius.Work as bottleneck
When producing certain inclination angle, being separated from beyond directly over body test point once bottleneck, detection device is i.e.
Think on conveyer belt with the presence of bottle, then send alarm or shut down.The installation site of the detection of falling bottle sensor is such as
Shown in Fig. 1.
The detection height of the present invention and the determination method at detection inclination angle include:
Empty bottle inspection scan line is at bottleneck peak, and this is minimum for ensureing detection inclination angle, and accuracy of detection is the highest；
Body detection scan line body radial height at the bottom of bottle.When the bottleneck of bottle is just off corkage body detection
Time beyond directly over Dian, it is judged as down bottle, with reference to the size marking of Fig. 1, calculates the minimum angle-of-incidence of bottle
α is:
In formula, R is body radius, and r is bottleneck radius, and H is the height of bottle.With 500ml standard medicated beer
Bottle (R=75mm, r=26mm, H=238mm) is as the criterion, and the detection inclination angle of calculating is about 15 degree, the most just
It is to say that when angle of inclination is more than 15 degree, this device can detect down bottle.Actual test is when bottle inclination angle is less than 20 degree
Shi Chongxin still at the bottom of bottle with inner, can just return voluntarily by action of gravity bottle, when inclination angle is more than 20 degree center of gravity from
The corkage end then bottle can fall down, and more than the 20 degree real bottles that fall are bound to be detected by this device, when inclination angle exists
During 15～20 degree of scopes, actually bottle is in serious vibrating state, and this device can alert bottle, although
Belong to by mistake alarm, but more than 15 degree to rock ratio more serious, this by seriously rocking shifting to an earlier date of initiation
Alarm just one desired as a result, it is possible to guarantee the credibility of apparatus of the present invention testing result.
The processing method of the two-way photoswitch detection signal of the present invention includes:
Two-way detection signal gives a quaternary enumerator being made up of two-way d type flip flop, body detection letter
Number as the count pulse of enumerator, empty bottle inspection signal is as the reset signal of enumerator.One bottle meeting
Two pulse signals being detected, when bottle edge just starts to block laser beam, photoswitch turns on, signal quilt
Dragging down, when bottle center being detected, signal transmission is equivalent to no bottle, and now signal reverts to height, when in bottle
When the heart leaves laser beam, signal is pulled low again, and when bottle just leaves laser beam, signal reverts to height,
Body detection signal negates process finally by audion as signal.
Detection device normally works and the time of falling bottle detects the waveform of signal as shown in Figure 2.According to whether occur to fall
Bottle or Cancellation Missed, do and process as follows:
(1) occur without bottle/Cancellation Missed, then enumerator be in " counting > reset > counting > clear
Zero " cyclic process, at most meter is to 1；
(2) if having down bottle or Cancellation Missed, then enumerator is in continuous counter state, when bottleneck has exceeded bottle
During body sweep limits, no matter swinging to that direction, a bottle also can make enumerator with regard to accounting to 2, then count
Device meter alerts and self-locking after 2 immediately, and externally output open and close two-way relay signal, can connect main frame control
Circuit processed causes shutdown, or connects the only alarm such as alarm indicator, buzzer and do not shut down, and once alerts
Only by releasing by releasing alarm switch.
The mentality of designing of the Cancellation Missed detection device that apparatus of the present invention relate to is similar to the detection of falling bottle device.The most still
The photoswitch scanning body that old use is identical with the detection of falling bottle, the difference of two devices is that bottle is detected in top
Mouth is not photoswitch, but the proximity switch of special detection metal object.Proximity switch just going up at bottleneck
Side, normally complete filling liquid and press the bottle of bottle cap on a moving belt by time, body detection light is established by cable
Closing to rolling counters forward pulse signal, bottleneck proximity switch, to counter O reset pulse signal, makes at enumerator
In " counting > reset counting > reset " reciprocation cycle process, if there being the bottle of Cancellation Missed, then one
Bottle counter counting does not resets for 2 times, count down to when 2 send alarm, instruction conveyer belt has Cancellation Missed
Bottle, alarm self-locking is until artificial removing, and Cancellation Missed detection device normally works and signal waveform such as Fig. 3 during Cancellation Missed
Shown in.
The main devices type selecting of apparatus of the present invention is based on low cost, the starting point of use economy, selected main device
Part includes photoswitch, proximity switch, d type flip flop, audion, expansion stream chip, relay and externally
Control output interface.
Concrete type selecting case:
Autonic company of Korea S direct reflective switch BEN300-DDT selected by photoswitch；
Proximity switch selects the PR18-8DN belonging to Autonic company together；
2 road d type flip flop chip 74LS74 are selected to be barricaded as quaternary enumerator；
Select audion realize not gate and with door；
Select ULN2003 as diffuser part；
Select OMRON company MY3N-D2 relay as alarm self-locking with to outer control output interface.
Owing to photoswitch waveform there are differences, enumerator alarming threshold takes 2 and still takes 3 needs according to reality
Demand is set, and circuit does compatible design, retains the output of enumerator low level and controls audion 0 Europe electricity in parallel
Resistance (or jumper cap) position, takes 2 and makees to weld 0 Europe resistance during warning value and do not weld 8050, takes 3 when making warning value
0 Europe resistance is not welded in weldering 8050, and hardware configuration and annexation are as shown in Figure 4.Package unit uses monolayer
PCB design can realize.
The mounting design principle of apparatus of the present invention includes:
Can be rest directly upon in conveyer belt static shelving, for ensureing reliability and improving efficiency, reduce bottle
The impact that enterprise is produced by event, can hold at the entrance of conveyer belt, outlet, turning etc. according to enterprise requirements
Occur the local of the problem of falling bottle installs a few set detection device more, once there is bottle, alert immediately, pass through people
Work cleaning releases alarm, recovers just producing product；
Before entering the fine equipment such as fill, a set of detection device is installed, once bottle be detected down, the most urgent
Shut down, it is to avoid the bottle equipment of being involved in that falls not processed in time causes equipment fault, leads to bigger problem；
After Cancellation Missed detection device is placed on cap pressing process, after Cancellation Missed being detected at timely alarm notification staff
Reason, the Cancellation Missed of falling bottle detection device typical case's application scenarios is shown in Fig. 5.
