Indexing refers to the motion of bottles or other containers into and from the fill region of a liquid filling machine. Once the bottles are in position, they will be held until the fill is complete. The bottles will then be discharged to move along the power conveyor into the next packaging machine. Without proper indexing, a packager can anticipate inconsistent fills, bottle jams, spills and other unwanted occurrences. Fortunately almost all automatic liquid fillers feature settings in the PLC and operator interface to make finding the suitable indexing settings easy.
Before we get to set the actual indexing times, there are several physical adjustments that will need to be created when conducting a bottle or container initially, or when switching from one bottle to another on the filling machine. The guide rails about the electricity conveyors that move the bottles to the fill region will need to be adjusted for the container being used. Guiderails which are too tight may hinder the progress of containers onto a conveyor, slowing down indexing occasions. Set the guide rails at an excessive width and containers can tip or lineup liberally beneath the fill mind e juice filling machine. This adjustment can be made simply by setting the container to be run on the conveyor belt and using hand knobs to adjust the manual rail width and height along with the conveyor system. The guide rails should offer support whilst at the same time enabling the bottles to maneuver freely down the line, simply touching a place of the bottle that will offer the required stability.
Once these power conveyors are corrected, bottles should be wrapped up in the fill area and under the fill heads. If moving from one bottle to another, the fill head position may need to be corrected. This, again, is easy enough to reach by loosening a hand and sliding the fill head into position over the line of bottles before re-securing the nozzle. As an example, if using pin indexing, the entrance and exit gates will need to be relocated behind the very first bottle and in the front of the previous bottle. These gates hold the bottles to be filled in position, but a different bottle or container shapes and dimensions will require unique locations for the pins. This is usually accomplished by means of a bolt to slide the pin into place. Starwheel and twist indexing systems might require altering out one-star wheel or screw for one of another size. Again, this is normally accomplished with the tightening and firming of a couple bolts.
Finally, once the indexing system has been set up, and with bottles still in place, the operator must add one additional bottle to the entrance aspect of the filling machine. The counting sensor reads each bottle as it passes into the fill region. When the right number of bottles have been”counted” the machine will activate the indexing method to prevent bottles in the correct position and begin each fill cycle.
Once the physical aspects of the indexing program are adjusted, the operator of the filling machine must come across the indexing time to get your container being run on the packing system. Most automatic filling machines may include several different screens on the operator interface. There are a few settings to check before setting the true index period. The operator interface will incorporate an Infeed Container Count Preset, typically under an Adjust Presets screen. This is the range of bottles counted for each fill cycle. However, with star wheel indexing, it’s normally set to one-half of the fill heads since the star wheel count functions together with the pins onto the star wheel. Under the Filler Set Up display, find the indexing type selection and be certain that the right indexing is chosen (pin, star wheel, etc.).
The final step, then, would be to set the true indexing time, which on most automatic filling machines requires significantly less time than the alterations mentioned above. With containers lined up to the electricity conveyor, one per fill head and one extra conveyor, the operator will visit the automobile Index Set-Up Menu. Once in the sub-menu, indexing times could be set to your particular container by pressing the Start ASU Index button. Containers will indicator through the machine and the detector will shut the gate to prevent indexing once the correct amount of containers has now passed. This indexing time can then be stored or the automatic set up could be conducted again to get a different moment.
Fortunately, operators of a liquid filling machine only need to go through this procedure once for every bottle to be conducted. Once the indexing instances are set they can be stored into a Recipe Screen to be recalled whenever that same bottle or container is run. In this way, the PLC and operator interface help cut down on changeover times and permit greater production on a daily basis.
