YM Packaging R&D project: doypack bags

The R&D department of YM Packaging is developing in collaboration with ELEPACK (UK) a new model of machine capable of making doypack bags from pillow bags.

With this innovation we are reducing the number of bags with inert gas leaks by a very high percentage, reducing production losses and problems for 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 packer, etc.).

Security

The machine is designed according to the standard UNE12100, which guarantees minimum safety requirements for the user.

On the other hand, the components used in this machine are of the highest 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 via a drop chute.
• The second station is where pressure testers check that the bags are airtight 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 a claw is located to shake 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 we apply two dots of hot melt glue.
• The seventh station is where the bag extractor to the outfeed conveyor is located.
