NovaStar, MP229, Roll Pack Machine with Hydraulic Press, 25 Tons, 2200x2200mm

NovaStar, MP229, Roll Pack Machine with Hydraulic Press, 25 Tons, 2200x2200mm

Description

  1. Overview
    1. Sturdy welded carbon-steel structure on which the following groups are mounted.
    2. Machine developed to roll/pack mattresses in latex, memory, viscolatex and polyurethane in order to reduce their volume and make handling and transport easier.
    3. Mattress is manually put in a polyethylene bag to be pressed and rolled.
    4. It is possible to adjust the diameter of the rolled mattress.
  2. Working Procedure
    1. Operator inserts the mattress into the proper polyethylene bag, puts it on the neutral roll conveyor and pulls it on the motorized conveyor belt that carries the mattress under the open press where a photocell controls its correct positioning.
    2. Press movable plate, driven by hydraulic cylinders, compresses the mattress to the thickness corresponding to the programmed pressing force and the welding bar, driven by pneumatic cylinders, presses the polyethylene films against the counterblade, welding them and sealing the bag.
    3. Press movable plate opens, the conveyor belt carries the compressed mattress towards the rolling-up unit where the roll-packing operation is executed.
    4. At the rolling-up phase end, a welding bar welds the tail of the polyethylene bag, securing the packing and the movable part of the rolling-up unit opens ejecting the roll-packed mattress.
  3. Machine Components
    1. Neutral roll conveyor positioned in entrance of the machine to support the mattress.
    2. Transversal welding-bar unit with pneumatic motion, length = 2500 mm. The bar is heated by an electric resistance; the temperature is controlled by a thermocouple. The welding bar is coated with teflon, granting an easy detachment of the plastic film and avoiding the sticking of film residuals which could compromise the welding area.
    3. Rolling-up unit. It is possible to roll only full pressed mattresses. It is composed by an entrance calander group that conveys the pressed mattress into a belt that gives the possibility to roll the mattress. This unit is provided of a welding hot bar to seal the plastic bag after the mattress has been rolled. The belt, driven by two pneumatic cylinders, can be opened for the automatic ejection of the roll-packed mattress. It is possible to adjust the diameter of the rolling mattress by action on the pressure of the dandy-roll.
    4. Electric cabinet unit with control panel. Memory of up to 99 work recipes to recall as function of the mattress to roll. The operator has to prepare one work recipe for each different model of mattress to roll.
  4. Technical Data
    1. Electrical supply: 400 volt – 50 Hz
    2. Electrical power: 12 kW about
    3. Pneumatic power: maximum 6 bar
    4. Maximum size of the mattresses: 2200 mm x 2200 mm x 400 mm
    5. Plastic bag size: the length of the plastic bag needs to be almost 80 mm longer than the size of the mattress.
    6. Cycle time: total time 30/50 sec.
    7. Press: maximum force 20 tons.
  5. Optional
    1. Neutral entrance rolls-conveyor
    2. Length 2000 mm
    3. Width 2000 mm
    4. Height 1000 mm
