QING series features automatic machines for packing plastic, metal, cardboard or glass containers.wraparound packers run up to 30 packs per minute, depending on the product handled and on the packing pattern.Diferent pack collations can be formed according to the container’s shape, capacity and dimensions; themost popular formats on the market are 2x3, 3x4 and 4x6.OING series packers are equipped with a mechanical product-grouping system and manual formatchangeover.
At the machine infeed, a group of guides lines up loose containers along a conveyor belt featuring low-friction chains made of thermoplastic material. In the pack-forming unit, products are grouped in the chosen packing pattern by means of an alternate-motion pneumatic device.
A sheet of corrugated cardboard is picked from the blank magazine by an alternate-motion picker with vacuum suction cups; the cardboard blank is carried along the blank ramp and positioned under the incoming pack collation with short leading side. The box/tray former operates in continuous motion with a wraparound system.
Later on, flap-folding devices fold first side flaps and then upper/lower flaps on both the front and the back of the pack. A gun sprays a thin layer of hotmelt glue on the flaps to ensure perfect endurance of the box.
At the machine outlet, the case walls are pressed by special guides. Such system ensures perfect and durable pack squaring, if compared to pressing systems with rotating chains (which cannot provide the same quality standard).
