Sprue pickers

The SPARK and PIRANHA model manipulators have both been designed mainly to extract sprues from moulds: using these devices allows both the automatic separation of the sprue, as well as the immediate recycling of the material. Moreover it is guaranteed that the sprue will not remain inside the mould when it closes.

The high speed of movement allows a significant lengthening of the cycle time, especially when using the PIRANHA model.

The main difference between the two models is related to the axis movement: with pneumatic cylinders in the case of SPARK, and 3 brushless motors for PIRANHA.

With the PIRANHA model it is also possible to simultaneously extract the moulded piece and the sprue, then release them at different points.

TECHNICAL FEATURES MOD. “SPARK” (PNEUMATIC)

  • Very sturdy structure,
  • Hydraulic limit shock absorbers,
  • Movements on prismatic guides with recirculating ball bearings that ensure the absence of play over time,
  • Very easy to use,
  • Mounted on a fixed surface,
  • Height adjustment via a micrometer screw,
  • Quick adjustment of the sprue extraction point via a release lever,
  • Possibility to choose the side of sprue release (operator side or the opposite side),
  • Possibility of working with three-plate moulds,
  • Lateral rotation of the entire manipulator to facilitate mould changing,
  • Handheld keypad with backlit display,
  • Choice of various of program types,
  • Monitoring of all inputs and outputs of the microprocessor,
  • Possibility of introducing pause times at each point of the working cycle,
  • Displays alarm messages,
  • Resettable cycle counter.

OPTIONAL FEATURES

  • Vacuum generator kit,
  • Clamp rotation kit.

TECHNICAL FEATURES MOD. “PIRANHA” (ELECTRIC)

  • Movement of the three axes with brushless servomotors,
  • High speed axes,
  • Free guided programming (FGP), via copy/paste “actions” taken from a specific library,
  • Remote control keypad, 7” colour touch screen display,
  • Very easy to use,
  • Work programs can be stored on a USB pendrive,
  • Displays alarm messages,
  • Interpolation and superposition of the axis movements,
  • Movements on prismatic guides with recirculating ball bearings that ensure the absence of play over time,
  • As standard: rotation of the gripper and the vacuum circuit,
  • Ability to perform various movements with any sequence and with strokes that can be set as desired,
  • Ability to extract the workpieces and the sprue at the same time and then release them in separate locations,
  • Mounted on a fixed surface,
  • Possibility to work both towards the operator side and towards the opposite side,
  • Possibility of working with three-plate moulds,
  • Lateral rotation of the entire manipulator to facilitate mounting the mould,
