Omron the application of laser measurement system in tobacco equipment

At present, with the tobacco industry is more and more strict laser tobacco equipment application Omron with laser tobacco equipment application Omron the quality of products, the tobacco industry to enhance competitiveness, improve the production efficiency, and have introduced a large number of fully automated test equipment backward artificial sampling method instead of the original. Such as machine vision <a href="/searchfanan.html?search=system&select=7">system has been in many key lengths on the occasion, omron products of machine vision in the packaging machine also packet inspection, article big appearance appearance on topics such as a wide range of applications. But cigarette factory for a long time for roll machine YanZhi accumulation error and did not have a good online testing way, still adopt the method of artificial sampling, lead to the production efficiency is low. For this topic recently, omron joint famous German rainbow (HAUNI) tobacco machinery manufacturer, to develop the automatic measurement system based on laser displacement sensor.

YanZhi volume in the charter at the same time there will be about 4000 branches (or filter) into a YanZhi storage (Tray). YanZhi is staggered arrangement, look from the device, the overall accumulation effect like a beehive. Germany rainbow company earlier COMFLEX cigarette storage transport system developed by the Tray plate machine and discharging machine two major part, main effect is to roll the unit and flexible packaging unit linked stable, complete cigarette storage function. When volume by units or packaging units output does not match, can be done automatically YanZhi storage and supplement. But in the process of YanZhi filled or empty, also can have a variety of problems, such as a full storage likely to cause YanZhi damage, leading to packing can't keep consistency; Storage tank is empty, sometimes, on the other hand, there may be vibration YanZhi bounce, causing the top YanZhi YanZhi not in parallel with the lower, so in the transport chute, the top askew YanZhi will hinder other YanZhi into, such as site operation personnel is not found in time and solve these heterogeneous, can only stop cleared, the serious influence production efficiency.

In more common solution is to use machine vision products for automatic detection, but also on the application of machine vision products weakness, such as vulnerable to environmental disturbance, set system is complex, the price more expensive, and so on. Omron now united Germany rainbow company have successfully developed a system solution based on laser displacement sensor, using two sets of laser displacement sensor (ZX - LDA41 + ZX - LD100L) attached to the store on parallel are at opposite ends of the machine arm. When the arm seized storage machine, two sets of laser sensor automatic YanZhi to the top of a real-time detection sensor of vertical height, the depth of the detection range covers the whole storage. The other with a simple calculation unit (ZX - CAL) with two sets of sensors measured height value is presupposed, if placed YanZhi is correct, then the height of the measured values should be the same on both sides of the, calculus unit of impairment should be 0, meaning that everything is ok. If there are YanZhi asymmetric skew namely is put to be able to get readings, then one of the sensor motor drive mechanical arm started to send the number of pulses storage until another sensor to stop signal is given. The pulse number shows the arrangement of storage tank top condition, such as the previously set value, the storage tank that is marked as can enter the next process, on the other hand, by the measured height value can also know how much is the amount of the storage tank has been stored. So the scheme can be used to real-time monitor each empty storage YanZhi storage conditions.
