• Welding set is mounted on linear rails, for easy movements.
• Each welding unit is used for welding of only one longitudinal bar to the cross bar.
• Cascade welding is possible as option in the control unit

TRANSVERSAL WIRE FEEDER

• Structural steel section
• Automatic loader for dispensing the bars, inclusive of unit for fast positioning of the bars at the welding position.
  
  

WIRE MESH PULLING DEVICE/TRANSVERSAL WIRE POSITIONING UNIT

This group is composed of a structural steel section with following components included:

• Structural steel construction
• Linear guide system - 6m long
• Servo positioning cart with pneumatic grippers
• 12 m long table for supporting of finished mesh

ELECTRIC, ELECTRONIC EQUIPMENT, CABLE & INSTALLATION ACCESSORIES

 Subdivided in:

• Switch cup-board
• Control board
• Security push button
• Set of various motors in quantity and characteristics in conformity to the plant
• Cable and installation of the accessories set for the interconnection between switch cup-board and the machine.

Options:

EVACUATION OF MESH PANELS AND POSITIONING:

• Evacuation of mesh being produced, by a cart system with finger-gripper-system to take and guide the mesh panels out of the mesh welding machine and position it on a table made by steel structure, with motorized rollers to bring the mesh complete out and to the end of the table.
• Collecting table made in solid steel structure.
• 10/11 chain conveyor which move up and down at the receiving table (last part of evacuation table) as well as the side table where the mesh will be delivered. The chain conveyors are integrated in the table and come in action once the mesh is produced and at the end position.
• All electrical wiring and el motors/el-servo motors to control all movements of the system
• Control unit integrated in the mesh welding line control panel.

EVACUATION OF MESH PANELS AND VERTICAL BENDING

• Evacuation of mesh being produced, by a cart system with finger-gripper-system to take and guide the mesh panels out of the mesh welding machine and position it on the receiving table
• Collecting table made in steel structure, with free-wheeling rollers to limit the frictions
• Hydraulic lifting of the mesh panel, with grippers which hold the mesh firm and in position Pos 9 until the robot arms pos 12 and 13 takes over the mesh.
• Robot arms are placed on a solid steel structure with guidelines on top for robot arms Pos 11
• After the mesh is positioned in robot arms 12 and 13, the mesh is moved forward into the vertical mesh bender and an automatic mesh bending is taken placed as pre-programmed – pos 14. A support with rollers are placed under the mesh to support it during bending. After the mesh has been bend, a crane must remove the bended mesh
• All electrical wiring and el motors/el-servo motors to control all movements of the system
• Control unit integrated in the mesh welding line control panel, where the positioning’s are given by operator, i.e. height between 2 mesh panels
