AUTOMATIC BAG PLACER
Automatic bag placer model ILERSAC A has been designed to handle paper, PE or woven PP open mouth bags, reaching capacities up to 720 bags/hour.

It can incorporate any product dosing type on top depending on the product to be bagged either in gross or net weight configuration.

STATIONS

• Empty bags magazine
  It has two trays where empty bags are stacked. It incorporates adjustment for different bag sizes. It has a total autonomy of 250-300 units depending on thickness and bag type.
  Change of tray is done automatically once one of them is empty. This is detected by a photocell. Driving is done pneumatically guided. Motion is smooth, silent and without vibrations. An acoustic alarm sounds during changing process.
• Bag catching group
  It is formed by a main body where different vacuum cups are located. They can be easily adjusted on guides.
  Frame is driven by pneumatic cylinder with two movements to proceed with the complete catching cycle.
  • Vertical: system goes up and down to take the empty bag and raise it from the stack.
  • Frontal tilting: system tilts and delivers the empty bag at the level of main frame where bag opening station is located.
• Bag opening station
  Frontal vacuum cups tilt up once empty bag is delivered into the opening station for a pre-opening action. A lower cup acts at the same time. Both simultaneous actions allow the opening arm to enter into the bag mouth and take it by pressure at both inner sides of bag.
• Placing arms
  Placing arms have the bag caught by its sides and tilt 90º up to deliver it open to the filling spout.
• Filling spout
  Inner opening pneumatic filling spout adjusts to different bag sizes by pressure detector. Side dams permit tightness during product discharge.
• Bag mouth stretching and flattening
  Two pneumatic fingers enter into the bag mouth and stretch both sides outwards once product discharge is over and filled bag is released from filling spout. Then, a squared plate flattens the bag mouth and delivers this guided to the closing equipment.
• Quick exit belt conveyor
  Filled bag is removed from filling area by means of a short belt conveyor driven by frequency inverter. This belt runs at high speed allowing fast placing for next empty bag.
• Closing belt
  It is a motorized belt conveyor placed after quick exit belt. This is also equipped with frequency inverter for synchronization with closing equipment – stitching, sealing or gluing -.
• Height adjustment for exit belts
  Both quick and closing belts are supported onto an only main frame with height adjustment by wheel. There is an only adjusting point this way.
• 90º bag pusher
  This pneumatic pusher is placed at the end of closing conveyor. Pushing action is done parallel to the belt level – bag bottom – to avoid adjustment for different sizes. Pusher delivers bags 90º with bottom ahead for a right later conditioning – product spreading inside the bag - by means of bag flattener or any other system.

APPLICATIONS
Open mouth sacks: paper, polyethylene, woven polypropylene

OPTIONS

• Side kicker
  Bag placer can be equipped with a pneumatic side kicking device for product settling inside the bag. This is mainly useful for flour-type products.
• Motorised height adjustment for exit belts
  Motorized height adjustment makes easier lifting belts. It also allows including all parameters at touch-screen to work trough recipes.
• Tight-proof filling spout
  It is suitable for fine products. It includes the necessary tight adjustment to avoid any product leakage during filling process. Side adjustments incorporate de-dusting nozzles to be connected to filter.
• Bag lifter for quick exit belt
  It is suitable for fine products. Bag is not release from filling spout but quick belt goes up to pick it in order to avoid powder generation by impact when unloading.
• Bottom vibration
  Quick exit belt can be equipped with a vibrating system to settle product inside the bag.
• Motorized bag top guiding system
  It is suitable for fine products. Once bag is filled, stretched and flattened by its mouth, this is taken by a set of motorised belts that take it and deliver it to the closing system infeed belts. Horizontal delivery of bag is assured this way, otherwise bag becomes unstable and right delivery to closing system cannot be guaranteed.
• Kit for handling of side-gusseted bags
  
  • It is composed by 3 modules:
  • _Bag catching station: it incorporates side separators that act once the bag on top of the pile is lifted up. It impedes that bottom side of bag mouth collisions against main frame during transfer to opening station.
  • _Side pincers at filling spout. They keep the gussets closed to deliver them this way to the guiding for its later closing.
  • _Motorized bag top guiding system. It assures right position of gussets during transfer for its later closing.
• ATEX Version
  It is equipped with homologated and certified components to work into ATEX 21-22 Classified Area. It is suitable for handling of products with low ignition temperature such as wheat flours or starches.
• Anti-corrosion version
  It is equipped with components and materials prepared for handling products with high corrosion level such as salt or fertilisers.
