Cartesian take-out robot
Straight-line axes enter the open mould and carry parts to a defined destination. A beam, traverse carriage and vertical arm position the end-of-arm tool. Motions are coordinated with mould opening and ejection. Linear robots suit repeatable pick-and-place paths; layout and entry direction depend on the cell.
Interfaces
Machine cycle signals · Robot controller · End-of-arm tool · Conveyor or fixture
What to investigate
- Clearance around tie bars and ejectors
- Payload including tooling
- Repeatable deposit location
Six-axis articulated robot
Rotary joints orient a gripper for extraction, insertion, inspection and assembly. Serial joints give the tool more freedom of orientation than a basic Cartesian handler. A moulding cell may use this flexibility for inserts, reorientation or downstream operations. Each path still has to fit the real machine and tooling envelope.
Interfaces
Robot base · Joint drives · Wrist flange · Cell controller
What to investigate
- Reach at the required tool orientation
- Tool mass and offset
- Hose routing through the motion
End-of-arm tooling
The product-specific contact between the robot and the moulded part. A structural frame locates suction cups or mechanical gripping elements on surfaces that can support the part. The complete tool includes mounts and the services needed to hold, detect and release it.
Interfaces
Robot wrist flange · Part contact surfaces · Vacuum or pneumatic lines · Part-detection feedback
What to investigate
- Cup contact and sealing
- Support for a warm part
- Tool access to each cavity
Vacuum generator and sensing
Creates and monitors the pressure difference used by suction cups. A pneumatic ejector uses compressed-air flow through a Venturi nozzle to draw air from the cup circuit. Compact units can combine suction control, blow-off, sensing and air-saving regulation.
Interfaces
Compressed-air supply · Vacuum hose · Suction cups · Robot input/output
What to investigate
- Leaks at cups and hoses
- Time needed to establish grip
- Vacuum confirmation before transport
Desiccant dryer and drying hopper
Conditions hygroscopic resin before it reaches the barrel. Heated dry air passes through the pellet bed. Successful drying depends on resin-specific temperature and residence time, sufficient airflow, and suitably low dew point. A dew-point reading alone does not establish pellet dryness.
Interfaces
Dry-air supply and return · Pellet hopper · Material loader · Resin processing specification
What to investigate
- Residence time at actual throughput
- Air temperature at the hopper
- Airflow distribution and dew point
Vacuum material loader
Transfers pellets or permitted regrind into a hopper using an air stream. A self-contained loader provides suction at the destination. Material travels through a conveying hose, separates from the air and discharges into the receiving hopper. Central systems instead share vacuum generation among receivers.
Interfaces
Material pickup lance · Conveying hose · Filter · Hopper demand signal
What to investigate
- Correct material source
- Filter condition
- Conveying interruptions
Material receiver and discharge valve
Separates conveyed pellets from transport air and releases them into the hopper. The receiver sits above the consuming hopper. Its filter retains material while air continues towards the vacuum system; a discharge valve opens after the loading sequence. Fill or demand sensors coordinate replenishment.
Interfaces
Vacuum line · Material inlet · Hopper outlet · Level sensor
What to investigate
- Discharge bridging
- Filter loading
- A demand signal that never clears
Gravimetric blender
Combines measured ingredient masses into a repeatable batch. Metering valves feed virgin resin, permitted regrind and additives into a weigh bin. A mixing chamber combines the measured batch before discharge. Weight feedback distinguishes gravimetric dosing from a purely volumetric feeder.
Interfaces
Ingredient hoppers · Load cell and weigh bin · Mixer · Machine feed path
What to investigate
- Correct recipe and material
- Free movement of the weigh bin
- Stable batch weights
Volumetric additive feeder
Meters an additive by controlled displacement over time. A dosing cylinder or screw delivers material according to speed and operating time. The quantity delivered for a setting depends on the material and calibration; the cited WITTMANN unit uses a dosing cylinder.
Interfaces
Additive hopper · Metering drive · Machine cycle trigger · Feed throat
What to investigate
- Calibration after a material change
- Consistent feed
- Pulsing or bridging
Mould temperature controller
Circulates conditioned fluid to control mould temperature. A pump moves fluid through the mould circuit. A heater supplies energy during warm-up or when required, while a cooling system removes energy. The controller regulates the circuit around its setpoint; the cavity surface still has its own changing temperature.
Interfaces
Mould supply and return · Cooling-water service · Temperature sensor · Pump and heater
What to investigate
- Supply and return temperatures
- Circuit flow
- The distinction between fluid and cavity-wall temperature
Process chiller
Removes process heat through a refrigeration cycle. Coolant collects heat from the process and returns to the chiller. Refrigeration moves that heat to a heat-rejection system and provides coolant for recirculation. A TCU and chiller can perform different roles in the same cell.
Interfaces
Process-water loop · Refrigeration circuit · Air or water heat rejection · Pump and reservoir
What to investigate
- Heat load at operating conditions
- Supply and return temperatures
- Heat rejection and flow
Cooling manifold and flow monitor
Distributes coolant and makes individual mould circuits observable. Separate branches connect to cooling circuits. Depending on the device, flow and temperature can be indicated, monitored or regulated. Circuit-level readings help reveal an imbalance that a single overall supply reading can hide.
Interfaces
Main supply and return · Individual mould hoses · Flow sensor · Temperature sensor
What to investigate
- A changing branch flow
- Incorrect hose connections
- Differences between circuits
Beside-the-press granulator
Reduces runners or approved scrap to smaller particles. Cutting elements reduce feed into regrind that can be collected or conveyed. Granulator geometry and screens vary by design. Reuse suitability remains a material and product-quality decision, separate from the ability to grind a part.
Interfaces
Runner or scrap feed · Cutting chamber · Regrind collection · Material conveying
What to investigate
- Material identity
- Particle consistency and fines
- Separation of incompatible scrap
Conveyor and buffer station
Moves extracted parts through the cell and provides controlled accumulation. A conveyor links robotic unloading with inspection, cooling, assembly or packing. Buffer positions can decouple operations with different timing. Carriers or fixtures can preserve orientation for a later station.
Interfaces
Robot deposit point · Part carrier or belt · Downstream station · Presence sensors
What to investigate
- Part orientation
- Space for accumulation
- Downstream blockages
Vision inspection station
Uses controlled imaging to inspect a defined set of visible features. A camera observes the part at a repeatable position. Lighting, presentation and an inspection program determine what can be detected. The cited cell checks dimensions and flash; a camera cannot establish every material or internal property.
Interfaces
Part fixture · Camera and lighting · Inspection program · Reject or accept routing
What to investigate
- Lighting stability
- Repeatable presentation
- Traceability of inspection results
Robot–machine interface
Coordinates whether the machine and robot may proceed with their next motions. A defined interface exchanges states such as mould open, mould area free and permission to close. EUROMAP 67 includes electrical control and safety-related signals. This atlas illustrates the handshake concept, not an installation wiring scheme.
Interfaces
Machine controller · Robot controller · Safety-related circuits · Cycle permissions
What to investigate
- Agreement between physical position and reported state
- The order of permissions
- Fault-state behaviour
