Cobra Series-Inverter/Pneumatic-Driven Large Beam robotsCobra Series-Inverter/Pneumatic-Driven Large Beam robots
  • COBRA series is applicable to all types of horizontal injection molding machine ranging from 300t to 4000t for take-out of products and sprues. It has single stage and telescopic type; It can be added a sub-arm for 3-plates mold to grip products and sprue at the same time. Vertical stroke: 1200-3000mm, driven by pneumatic cylinder. For standard model, the traverse axle driven by inverter motor, AC servo motor is optional. Vertical and crosswise driven by pneumatic cylinder, cost-effective. According actual requirements, you can choose AC servo motor driven on product arm to increase efficiency. After installed Cobra robot, the productivity will be increased 20~30%, reduce defective rate, ensure safety of operators, reduce manpower and accurately control the output to reduce waste.
  • Structure
    • Traverse axle can be driven by rodless cylinder or inverter motor, AC servo motor is optional. Vertical and Crosswise driven by pneumatic cylinder. Traverse axle, crosswise and vertical arm are applied with advanced high rigidity linear slide rail, and light high rigidity alloy aluminum extrusion beam for Crosswise and Vertical axles. Integrating with linear guide and high rigidity bearing steel rod, it works with high speed, high efficiency, low vibration, and long use life. Optimum grouped design, high interchangeability between all parts and components.
  • Telescopic Type
    • Using high rigidity linear slide rail and alloy aluminum structure beam with special double-speed belt, substantially shortened the robot vertical height, and the full stroke can be achieved by half stroke of the cylinder. Thus it increased speed and stability of vertical axle. Furthermore, it can be applicable to low workshop.
  • Air Pressure Inspection
    • Automatically detecting air pressure. It will alarm and display while pressure is not enough, and twitch anti-drop cylinder automatically to prevent the arm from dropping.
  • End of arm Tooling (E-O-A-T)
    • Reserved pipeline and detecting signal, a vacuum circuit and a grip circuit, can be used for vacuum/grip tooling for different products with various actions. Swivel structure can take out products cooperated with mould and fixed mould, fixed swivel angle: 90 degrees.
  • Control box was combine with structure to save space:
    • Palm controller with dialogue type operation interface.
    • Easy to operate, and the display language is changeable.
    • Built-in programs enable easy operation in molding change. With L/U take out function can be integrated with placing methods, swiveling choosing, ejector setting and defect alarming, etc.
    • Automatically defecting, displaying and recording the failures.
    • Twenty groups of molding memorizing function.
    • Take out from fixed-mould side with various kinds of swivel actions.
    • Different placing method(traverse-out, traverse-in, out-side and place at the same time) are available.
    • All the Timer and Counter can be changed under AUTO MODE .
    • Grouped PC board design facilitates changing and maintenance; Pay special attention to safety connection with I.M.M, all I.M.M input and output signals of are dry contacts signals to avoid interference.
    • With standard interface can be connected with Vertical Transporter or conveyor.
    • Standard interface to connect the vertical transporter or the conveyer.
    • CE models are available, conformity with EUROMAP and SPI standard, enclosed standard connect interface.
    • Middle-Plate Inspection, Spray Device, Air Nipper and Safety Placing detecting are available to operated with automatic application of the factory.
  • Optional Function
    • Remote control adjustment for kick stroke and position: Kick position and stroke adjustment by AC motor to remote adjustment (one arm is added two motors), saving adjustment time and increasing operational safety.
    • Remote control adjustment for vertical stroke: Vertical stroke adjustment by AC motor to remote adjustment, saving adjustment time and increasing operational safety.
    • Traverse axle numerical control: Numerical controlled traverse stroke can be used to place products in multiple points (99 points at most) to stacking products.
    • Servo motor driven traverse stroke: Traverse axle can be driven by servo motor and applies precision planetary gear head reducer, fast and accurate. With positioning precision up to ±0.1mm, it can be used to precise take-out of the products.
    • Servo motor driven vertical axle: The vertical product arm is driven by AC servo motor, fast, time-effective and efficient. Different placing heights outside the mold can be achieved. The precision can be up to 0.2mm.
    • Spraying device: spraying number of molds and spraying time each time can be set. Spraying head can be installed on the arm or on the mold. Two devices at most can be installed.
    • Middle mold inspection: Position of the middle mold platen should be checked after mold opened end position, then runner arm can down to take-out a sprue. Avoid runner arm to hit middle-platen.
    • Photoelectric inspection on finished products: The sensor can be installed at conveyor. Place finished products on the conveyor to avoid hitting among products.
    • CE connectors: Connection with injection machine can be realized via EUROMAP 12 connectors.
    • Slow descending outside placing: avoid bruising to the operators.
    • Remarks: Only one function can be chosen among traverse axle numerical control, traverse axle servo motor driving and vertical axle servo motor driving.
