Automatic screw feeding with controlled tightening
From bulk screws to a finished joint: each screw is separated, fed and tightened automatically by a controlled Ingersoll Rand electric spindle.
New standard solution from Ingersoll Rand with screw feeder, feed hose and screwdriving head for a robot or XYZ manipulator.
The challenge
When every screw is picked and placed by hand, the work is slow, cycle times vary and the station is hard to automate.
The solution
A bowl or step feeder separates and orients the screws. Each screw is blown through a 4 m hose to the screwdriving head, where a sensor confirms that it has passed. The head holds the screw in position and a controlled Ingersoll Rand electric spindle tightens the joint. The system connects to factory PLCs and other automation.
Technical data
| Screws | Typically M3–M10, subject to a screw review. Also nuts and inserts |
|---|---|
| Feeding | From about 2 s per screw |
| Cycle time | About 3 s in suitable applications |
| Tool | Ingersoll Rand electric tools and spindles, e.g. IQi and QM. The tool is selected for the application |
| Monitoring | Sensor confirms every screw in the hose |
| Feed hose | 4 m |
| Mounting | On a robot or XYZ manipulator (robot not included) |
| Controls | Electrical and pneumatic schematics, PLC flowchart and a Siemens PLC template |
| Options | 5-litre hopper and a control box if the station has no other control system |
| Testing | Standard feeders are tested with 40,000 consecutive screws |
These figures apply to the standard design. Ingersoll Rand assesses every application from the screw drawing, a 3D model of the assembled part, the required cycle time and sample screws (at least 20 with the order). Price and delivery time are stated in the quote.
Describe your task
Tell us about the screw, the part and the required cycle time. Attach the screw drawing and a 3D model of the assembled part if you have them (PDF, STEP, DWG or DXF). At least 20 sample screws are needed with the order.
