YM Packaging R&D project: doypack bags
The R&D department of YM Packaging is developing in collaboration with ELEPACK (UK) a new machine model capable of making doypack bags from cushion bags. With this innovation we reduce by a very high percentage the number of bags with inert gas leaks, reducing production losses and problems at the end customer. This prototype will be operational soon and will serve as a first step for YM to develop a range of machines focused on perfecting the conservation of gas in the bags. The system is based on a carousel driven by a servomotor which is positioned in different stations and each one performs a function in order to reach a target speed of 40 bpm. This equipment is an independent machine, compatible with any vertical packaging machine on the market, as its electrical panel is also independent. The interface is managed by a 10-inch colour touch screen and can be linked to other upstream equipment (vertical packaging machine, preformed bag, etc.) as well as downstream equipment (metal detector, case packers, etc.). Safety The machine is designed under the UNE12100 standard, which guarantees minimum safety requirements for the user. On the other hand, the components used in this machine are top quality (Festo, Omron, Siemens...), to guarantee the correct operation of our machines. Operation The operating logic of the equipment is as follows: The first station is where the bag enters the carousel through a drop chute. The second station is where pressure testers check that the bags are tight and well sealed. The third station is where a load cell gripper checks the weight of the bag one by one to see if there is product inside. The fourth station is where a rejection claw is located, which is activated when it detects either a loss of pressure at station two or a lack of weight at station three. The fifth station is where there is a claw that shakes the bag to even out the product inside and level it. The sixth station is the folding station, where pneumatic actuators fold the bottom flaps of the bag and apply two dots of hot melt glue. The seventh station is where the bag extractor to the exit conveyor is located. This project has been co-funded by the Centre for the Development of Industrial Technology through the EXP 00102870 / IDI-20180020 file.
