I. Amarya ta Gargaɗi​
Wannan gargaɗin yana neman a kan rubutuwa masu taurari, ƙarfi da kuma mai kyau na kontrolin jikin don mekanismi na kai automata na safiya na aiki. A cikin wani abubuwan safiya na aiki, muhimmancinta na wannan mekanismi shine kai wasu aiki daga babban gida zuwa takamakon matarayya, ba su zama a haka tsawo lokacin da aka sani, sannan bayyana su zuwa mafi girma na aiki. Kukaɗanta na gargaɗin shine zaɓe waɗanda ake amfani da relay ta lokaci na DC electromagnetic don samun kontrolin lokaci na 2 detar daidai ga aiki a takamakon matarayya, domin ya tabbatar da ƙarfin aiki na aiki.

​II. Zaɓe da Kula da Tushen Masu Amfani Da Su​

​Relay ta Lokaci (Kukaɗanta na Kontrolin)​​

• Zaɓe: Relay ta lokaci na DC electromagnetic.
• Dalilai zaɓe:
• ​Ta hanyar:​​ Mekanismi na kai na safiya na aiki na da taurari da koyarwa masu kiyaye. Relay ta lokaci na DC electromagnetic, da sabon sauran, tsakiyar ƙarfi, da kuma adadin fadada da ake iya koyar da shi, yana da ma'ana da wannan buƙatun koyarwa.
• ​Kudin:​​ Daga baya da relays na motor na synchronus, shi ne da kudin da yake yarda, domin ya haɗa take tsara a cikin kudin na ƙasa.
• ​Matsayin Tsari:​​ Lokacin da aka bukata na 2 detar daidai yana cikin yadda ake amfani da shi (0.3–5.5 detar), da kuma kula da shi a lokacin da aka rasa asibiti shine matsayin da ake amfani da shi a cikin relay ta lokaci na DC electromagnetic.

​Haɗin Kula:​​ A cikin wannan gargaɗin, ana amfani da shi a lokacin da aka rasa asibiti. Idan aiki na cylinder na kai tana faru (signal na faɗa tana zama), ake rasa asibiti na relay ta lokaci, sannan contacts na lokacin da aka rasa asibiti sun faru. Ba lokacin da 2 detar daidai, contacts suka yi aiki, sun bayyana signal don karshen koyarwa ko bayyana mekanismi na kai.

​Cylinder da Magnetic Switch (Kula da Tushen Position da Actuator)​​

• ​Aiki:​​ Yana daidaita a canza positions na piston na cylinders na kai da kuma clamping (limits na gaba da gaba), sun bayyana feedback signals zuwa PLC ko circuit na kontrolin, ya kunshi tushen tsari na aiki na aiki.
• ​Muhimman Abubuwa:​​ Yana da sauransu da kuma hanyar sauran, da points na canza sun set da sliding da tightening bolts; wire na blue yana ɗauka zuwa common terminal, wire na brown zuwa signal terminal, da kula da standards na wiring.

​Single Solenoid-Controlled Directional Valve (Kula da Tushen Kontrolin Direction)​​

• ​Aiki:​​ Yana bayyana signals na kontrolin don koyar direction na airflow na compressed, domin ya kontrola extension da retraction na cylinders na kai da kuma clamping.
• ​Haɗin Kula:​​ Idan coil na solenoid yana ɗaukar asibiti, yana koyar spool, domin ya koyar cylinder; idan aka rasa asibiti, spring yana reset spool, domin ya koyar cylinder zuwa hakan ko ya ciwo a matsayin.

​Proximity Sensor (Kula da Tushen Canza)​​

• ​Aiki:​​ Yana amfani da shi don canza idan akwai workpiece a takamakon matarayya, domin ya bayyana trigger signal don relay ta lokaci don faru timing ko bayyana signal na safety verification ba lokacin da timing an faru.

​III. Haɗin Kula da Logic na Kontrolin na Mekanismi na Kai​
Daga cikin komponentoi na biyu, aikin automata na mekanismi na kai yana da haɗin kula:

1. ​Haɗin Kula Na Biyu:​​ Babban gidan yana da workpieces; piston rod na cylinder na kai yana ciwo (a tsohon gidan), da kuma piston rod na cylinder na clamping yana ciwo.
2. ​Trigger Clamping:​​ Safiya na aiki tana faru, valve na directional na single solenoid-controlled tana aktifar piston rod na cylinder na clamping zuwa gaba, domin ya kawo sub-layer workpiece domin ya kawo duk abubuwan da suka gaba.
3. ​Execute Pushing:​​ Ba lokacin da clamping an tabbatar (canzawa magnetic switch), valve na directional na single solenoid-controlled na biyu tana aktifar piston rod na cylinder na kai zuwa gaba, domin ya kai bottom-layer workpiece zuwa takamakon matarayya.
4. ​Pushing Return:​​ Idan cylinder na kai yana ci gaba (canzawa magnetic switch), solenoid valve tana rasa asibiti, da kuma piston rod na cylinder tana ciwo automatic.
5. ​Delay Start:​​ Ba lokacin da cylinder na kai tana ciwo (magnetic switch na rear tana canza signal), tana zama input signal na relay ta lokaci. Relay ta lokaci tana faru 2-second delay na rasa asibiti.
6. ​Release and Feeding:​​ A lokacin da delay na relay ta lokaci, workpiece tana ci hakan a takamakon matarayya, domin ya tabbatar da requirement na stabilization time na 2 seconds. Ba lokacin da delay an faru, contacts na delay na relay ta lokaci tana faru.
• ​Option A (Interlocked Control):​​ Wannan signal tana amfani don rasa asibiti na solenoid valve na cylinder na clamping, domin ya ciwo piston rod na release workpiece.
• ​Option B (Sequential Control):​​ Wannan signal tana amfani don trigger condition na karshen aiki (misali, start conveying mechanism ko initiate feeding cycle na biyu).
7. ​Cycle Completion:​​ Ba lokacin da cylinder na clamping tana release, duk abubuwan tana ci gaba da tsarin gravity, da bottom-layer workpiece tana ci hakan. Mekanismi tana ci haɗin kula na biyu, tare da shiga signal na biyu, da kuma cycle tana faru.

​IV. Muhimman Roli na Relay ta Lokaci​
A cikin circuit na kontrolin wannan gargaɗin, relay ta lokaci yana da muhimmanci wajen samun ƙarfin tsari:

• ​Implementation na Aiki:​​ Yana daidaita wajen tabbatar da requirement na process na "maintaining the workpiece on the material platform for 2 seconds."
• ​Operation Mode:​​ Yana amfani da power-off delay mode. Timing tana faru lokacin da cylinder na kai tana tabbatar da ciwo (signal tana zama) da kuma an faru 2 seconds later da output signal don kontrol karshen aiki.
• ​Advantage:​​ Wannan design tana tabbatar da delay tana faru ba lokacin da workpiece tana kai da kuma cylinder na kai tana ciwo safe, domin ya tabbatar da logic tana da ƙarfi, ƙarfi, da kuma mai kyau.
