VTC-100, Automatic Offset Coil Spring Transfer Machine, 4-5 and 4-4 Knotting Systems (New)

Description

  1. Overview
    1. The company has developed the machine with the aspiration to provide a robust machine that can serve for many years for mattress and spring units manufacturers.
    2. It can handle an unlimited range of different offset coil spring units for all kinds of mattresses and furniture thanks to its great flexibility.
    3. This machine is built to achieve the highest productivity with the maximum speed in the production of offset coil spring units.
    4. Offset coil production in 5 steps: the steel wire gets formed to a spring in the coiling machine; the springs are getting knotted at both ends; the springs get heat treated between two electrodes; the springs are getting transferred to the assembly machine; a spiral wire assembles the springs to get a finished spring unit.
  2. Highlights
    1. Consistent high performance: maximum speed for any type of offset coil spring unit; no slowdown during production of spring units for furniture.
    2. Improved transfer mechanism: patented technology; faster springs turning from horizontal to vertical position.
    3. More flexible production: simple production of different spring unit types; changeover within few seconds on the touchscreen display; very flexible and quick setting of the spring unit width.
    4. Full automated program: automation program ensures the production of different spring unit types without intervention; number of the requested spring units can be easily set on the touchscreen display; the automation program increases the productivity of spring unit manufacturers.
    5. Optimized design for furniture spring units: system offers the production of L-type spring units; the system allows the production of spring unit with no corners in certain areas for furniture spring units.
  3. Spiral Knotting Options
    1. 4-5 knotting system: the 4-5 knotting of the spiral wire allows the production of spring units with maximum firmness; this system reduces the range of motion for the offset coil springs.
    2. 4-4 knotting system: the 4-4 knotting of the spiral wire ensures the production of spring units with medium firmness; this system allows a small degree of motion for the offset coil springs; the working range of this knotting system is for springs in the diameter between 80-96 mm and wire diameter between 1.9 – 2.4 mm.
    3. 4-3 knotting system: the 4-3 spiral wire knotting provides the production of offset coil springs with maximum range of motion; this knotting system is designed for mini offset coil springs in the diameter 70-78 mm and the wire diameter 1.9 – 2.2 mm; this system offers the ideal solution to increase the number of springs on offset coil spring units.
  4. Automatic Lubrication System
    1. The automatic lubrication system ensures a periodic oiling of 22 points on the machine.
    2. The time frame for the periodic lubrication can be easily set up on the display.
  5. Digital Heat Treatment
    1. The digital heat treatment provides maximum durability to the offset coil springs.
    2. The temperature can be easily set up on the display.
    3. The heat treatment ensures that every spring is stress-relieved and strengthened.
    4. This process eliminates spring sag.
  6. Easy Height Settings
    1. The machine offers the easiest height setting technology which can be adjusted on the touchscreen display.
    2. This feature enables spring height adjustment completely automatically.
    3. Spring height adjustments are made on the precise linear adjustment tool.
  7. Easy Handling and High Security Standards
    1. The simple accessibility allows for more adjustments on the jaw system.
    2. The opening system of the assembly part is working completely automatic and there is no need to push or pull on the machine.
    3. The safety light curtains protect the operator of the machine.
    4. During the adjustments by operator the safety system does not allow the closing of the assembly part of the machine.
  8. Operation
    1. The machine produces and assembles offset coil springs into spring units automatically in a high production speed.
    2. The steel wire is located at the wire basket; this wire gets unwounded, coiled and cut to a raw spring; this raw spring is afterwards getting knotted at both ends and heat treated.
    3. In the next step the springs are swung from a horizontal to a vertical position and at the same time rotated around their axes and inserted into a belt conveyor; in this way all springs are ready to be assembled row by row.
    4. If programmed spring unit width is reached by necessary number of springs, the belt conveyor stops and all springs of one row are pushed by loading slides into the jaws of assembly machine.
    5. The jaw system is getting closed and two spiral wires connecting the springs on the top and bottom to form a spring unit; both spiral wires are being cut and bent at both ends joining this and the previous row.
    6. When the cycle of one spring row is concluded, the spring unit is getting pushed one step forward.
    7. This machine works without compressed air; it works with a clearly structured concept with an integrated motion control unit which is able to demonstrate, report and follow all product parameters and features on touchscreen control panel.
    8. Each jaw may be used as a knuckling jaw which allows a quick change-over to different spring unit widths up to 2000 mm.
  9. Equipment
    1. The automatic offset coil transfer machine includes 6 main parts: a heavy-duty swift basket useable for up to 1,000 kg of wire, including safety cage and switches; an automatic offset coil coiling machine with two knotting systems and a heat treatment unit, automatic lubrication system and a safety cage; a transfer mechanism; a conveyor system with safety cage and loading equipment includes 23 loading sliders; an automatic assembly machine with a maximum working width of up to 2000 mm and 23 jaws; an electronic system with Mitsubishi motion control system which works with 8 servo motors.
