Automatic Lines for Valve Bags

Automatic Valve Bag Filler Machine

The valve bag fillers are just machines that fill the product into the bag.

  • In this case the product has been already pre-weight by a net weigher (weigh hopper) above the filler.
  • There is a wide range of valve fillers according to the specific product to pack.

<p><strong>Automatic line that fills the bag with the product and weighs it simultaneously, until the bag reaches the programmed weight.</strong></p> <p>TECNO weighing-bagging machines are equipped with a screw feeder bag filling system. This versatile system is ideal for products with dusty or floury characteristics, yet they are also suited to granular or pelletized products. All product feed systems are equipped with dual phase filling modes (COURSE feed and FINE feed) to ensure precise dosing of the product.</p> <p>According to the product to be bagged, the machine may be equipped with one of the feeding systems: gravity, turbine, belt, screw feeder, double screw feeder, vibrating channel.  The bagging head – which receives the product from the dosing system – together with the whole filling structure (such as the screw feeder, bag-positioning device, etc…) is connected to the weighing system, which stands alone from the rest of the machine.</p> <p>The output of TECNO MT machines varies from 150 – 200 bags/hour.</p> <p>The electronic weighing systems feature a filling assembly that is supported by load cell and connected to the electronic weight controller. The weight controller it is composed by:</p> <ul> <li>A 7” colour graphic display that allows the visualization of the bag weights and may other parameters;</li> <li>An internal CPU to process all the weighing data.</li> </ul> <p>The main advantage of this electronic systems lies in their ability to constantly self-monitor and automatically correct for any changes product properties.</p> <p><strong>Optional:</strong></p> <ul> <li>TRANSFER automatic bag plácer;</li> <li>Automatic bag support height adjustment;</li> <li>Automatic bag kick-off on bag evacuation conveyor;</li> <li>Movable version on castors;</li> <li>SON SEAL ultrasonic bag sealer.</li> </ul>

Automatic weighing-bagging machine for valve bags TECNO

<p><strong>The empty bag, stacked on the bag magazine, is taken from the robotic arm, it opens the bag’s valve and position it on the fill spout, where a double detection device checks the proper placing to enable the packer to fill the bag.</strong></p> <p>The Transfer is so famous for its proven simplicity and reliability. At today we’ve sold and installed more than 2000 of those around the world.</p> <p><strong>It can reach a max speed of 400 bags/h. </strong></p> <p>The new TRANSFER – the further evolution of the industry recognized optimal automated bag placer for valve bags. Recently it was redesigned by adopting the latest actuation technologies further improving the automation. The implementation of closed-loop hydraulics renders all the various rotating and tilting movements especially smooth.</p> <p>Unlike conventional pneumatics, the hydraulics deliver a shock absorbing action, boosting fluidity in bag retrieval and bag feeding. Articulation is progressive and servo-like with no abrupt movement and impact against mechanical stops typical of conventional pneumatic actuation. Vibration is eliminated.</p> <p>The automation is completely silent: hydraulics does not require any cyclical discharges which usually generate noise due to the use of pneumatics. Empty bags are picked up by a specially designed pneumatic cylinder featuring a drilled shaft through which vacuum is drawn by a high reliable and maintenance free vacuum generator. This solution facilitated saving 50% energy over older designs, as the system works only when necessary.</p>

Automatic Bag Placer TRANSFER

<p><strong>The aesthetic appearance of the closed bag together with the valve sealing warranty are the requirements fulfilled with the newest technologies. </strong></p> <p>The system includes the employment of external valve-type bags with tab made of pre-glued polyethylene-coated paper to be sealed. It was conceived to be paired with any kind of bagging machine; in case of multiple bagging stations, each bagging machine shall be equipped with this device. The sewing phase occurs at the end of bagging action, and before re leasing the bag onto the outfeed conveyor belt.</p> <p><strong>Advantages:</strong></p> <p>Internal cleaning of the valve No contamination of the environment due to powder release.</p> <p>Sealing grippers closing control through electronic control (sealing intensity and closing time).</p>
