Bag Making Part

The bags are produced in a 4-up operation, the port end of the bag can be fitted with one (1) or two(2) components which are loaded.
The film is transported step by step through the presses by the indexing unit.
At the same time, the ports are transported via a special chain system.
In the first printing press, the next step are side welding. In the second welding press, of the ports is welded. The position of the presses cannot be changed.
The machine consists of the following components:

1. Material Unwinding Frame

• Roll diameter : max. 800 mm
  
• Roll width : max. 350 mm
  
• Number of Rolls : 1 working rolls, 1 spare roll
  
• Film : double-wound
  The film is drawn-off the roll by free driven dancing rollers.
  The working rolls are checked via a film sensor which stops the machine before the film runs-out

2. Printing station (Hot stamp) - Mounted on the machine frame, for printing of the bags

3. Ionized cleaner device

• Bag cleaning with total elimination of static electricity
  As through and reliable as series units are, air-wash type container cleaning alone isn't enough for certain applications.
  This is particularly true where bag are involved, because the molecular movement of synthetic materials charges particles in the air and causes particles in the air and cause them to stick to the bag.
  This can be a problem for any filling and packaging operation where clean room procedures, or simply a clean product, are required The reason: any bag supporting a static change will attract contamination in the form of microscopic dust particles.
  
• How FAC ionization keeps bag particle-free
  An ionizing device in the blower nozzles emits quantities of negative of a static charged object, such as the bottle being filled. Following the principle that opposites attract, the charged object takes on a sufficient number of negative or positive ions (whichever is required) to neutralize the static charge.
  Ionized bag cleaners are a most efficient, effective and economical way of keeping your product free from the contamination static charges can cause.

4. Port welding press

• Press force
  
• Infinitely adjustable to : max. 20 kN
  
• Upper press stroke : max. 15 mm
  
• Lower press stroke : max. 100 mm
  
• Welding area : approx. 140 x 350 mm x 4 set or other
  The press is quipped with an pneumatic drive. It is executed as a 4 column press with a centrally drive electrode upper plate which is quided via double V-guides the bottom table plate is driven pneumatically via a toggle lever system.
  When the press is closed, the ports are welded in two steps with the use of electric Heater (100 ~ 250deg. C.) adjustable.
  The top and bottom plates of the press are equipped with a tempering plate.

5. Electric heater welding press

• 1 Press force : max. 30 kN
  
• Press stroke : max. 100 mm
  
• Welding area : approx. 140 x 350 mm
  The press is equipped with an Pneumatic drive.
  It is executed as a 4 column press with a centrally driven electrode upper plate which is guided via double V-guides
  The top and bottom plates of the press are equipped with a tempering plate.

6. Lower press frame

• Consisting of a frame with rails mounted on the top, on which the indexing carriage executed with pneumatically actuated grippers moves.
  The indexing carriage is driven by electric motor.

7. Transport for ports

• To supply the automatic affixed components into the port pick up finger.
  Consisting of a horizontally move device with mandrel holders for one or two mandrels. To switch the production of bags from one to two ports or vice versa The chain is moved synchronously to the index movement.

8. Pneumatic equipment with exhaust system

• For the collection of the outgoing air of the pneumatic units so that it is possible to remove the polluted air (oil and particles) from the area.

9. Mandrel retraction device.

• Installed in the area of the peripheral welding press, pneumatically actuated, for retracting the mandrels from the welded ports.

10. Electrical control

• Built into a free-standing control cabinet, free programmable controller, Type Master K-1000.
• Brief description
  a. Machine specific required values such as
  Temperatures
  Pressures
  Are digitally stored
  b. Display of all set and actual values (LCD display)
  c. Functions of the machine via soft keys
  d. Error diagnostics in normal text
  e. Real-time clock

11. Safety guards - For the entire machine, consisting of safety doors with P. C glass.

12. Tempering units - For consistent electrode temperatures in the welding presses

13. Scrap station

• The scrap station is mounted on the extended frame rail.
  Mechanical grippers on the carriage of the Pneumatic cylinder unit across the machine at a 45deg. angle, the grid is dropped onto a scrap material box.
• Finished parts remover
  The welded bags are picked up by the vacuum suction cups and transported to a conveyor belt.

14. Sets port welding die - Consisting of upper and lower die for one and two port bags.

15. Peripheral welding die - Consisting of an upper die (upper die equipped with tear edges).
