Tips About Pipe Cutlery Injection Robot Selection

Axis Definition

injection robot

Tips: To select a suitable injection robot for your cutlery injection project, the speed and the cavities of the mould would be the key parameters for a selection of a suitable robot. The more of the mold cavities, the larger would be the size of the EOAT and which means an increase of the robot size and payload. Especially for an cutlery production system of multi-pcs box/bag packing.

Robot Sizing

injection robot
  • L: The max length of the robot
  • Z: The max distance where the parts to be dropped
  • Y: The max distance movabel of the robot arm from the standby position to the mold center
  • W: The width of the robot
  • H: The height of the robot
  • Hs: The height of the robot stand
  • YM1: The height from the standby position to the top of the machine
  • YM2: The distance from the Machine top to the mold center
  • X1: The max distance of the main arm from the mold platen
  • X2: The working stroke of the main arm
  • X3: The Min distance between the main arm and the sub arm of the robot
  • X4: The Max working stroke of the sub arm
  • X5: The Min distance from the sub arm to the mold platen

Robot Installation

injection robot
  • A -- Non-operator side installation of the robot
  • B -- Operator side installation of the robot
  • L -- The height of the crane
  • E -- The distance from the floor to the mold center
  • G -- The distance from the floor to the safe door rail
  • N -- The height from the top of the injection molding machine to the mold center
  • H/J -- Distance between the tia-bars
  • The Height of the Safe Door -- D-N

Tips: The primary principle of selecting a robot for your injection automatio project is that to make sure:

  • Picked: The robot arm can reach the mold center to pick the parts
  • Pickable: The robot has sufficient payload to carry the parts + EOAT
  • Pick out: There's enough in mold space to pick the parts out
  • Placeable: The parts can be carried over the safe door of the injection molding machine
  • Speed: The robot must be fast enough to match the injectio cycle
  • Arms: Choose single or double arms according to the mold type
  • Arm Type: Choose standard or telescopic arm according to the height of the crane
  • EOAT: For complex structure plastic parts, a set of custom made EOAT would be necessary
  • Special Requirement: For the robots to be integrated into an automation system, some special requirements would be requested, a custom made robot would be in this case

Q & A About A Cutlery Packing Automation System
  1. Will a cold runner cutlery mold suitable for an auto-packing system?

    There're two kind of cold runner molds for cutlery:

    The standard cold runner mold which the cutlery would be picked out with the runner, for this kind of mold it's not suitable for an auto-packing solution because of the unpredicatable deformation of the runner, it'll make the successful cutting of the runner impossible.

    The cold runner mold with submarine gate, for this kind of mold it's possible to seperate the cutlery from the runner in mold before robot picking, it's suitable for an auto-packing system, and most of the low budget cutlery auto-packing systems now are based on these kind of mold. It's an econonic solution of cutlery auto-packing system.

  2. Round mould layout or rectangular mold layout?

    Again it'll depends on your budget and your technical team:

    A round layout mould have a better runner balance but it's not friendly to a gantry robot to remove the well stacked cutlery to the packing machine, it means a more complex stacking system or have an articular robot to carry the well stacked cutlery to the packing machine.

    A rectangular layout mould is friendly to a two gantry robots cutlery packing system and most of the low budget cutlery packing system is based on this kind of mold design.

  3. Will there ba a auto-pcking system suitable for the packing of knifes, forks and spoons?

    The sharing of one automation system for different products is the common expectation of many small and medium producers of cutlery, but it's not easy to make it come true because of the different shape between these products. The solution is to make an independent collecting station and EOAT for each products and have them replaced in every mold changing.

  4. For a cutlery packing automation solution, what information to be provided to ensure a success of the project?

    For a cutlery packing automation system, the information what we need would be:

    1. The layout drawing of the mold
    2. The 3D drawing of the cutlery
    3. The details of the injection molding machine
    4. How do you want the cutlery to be packed
    5. The total cycle time
