Why Choose Fouk?
1. Fast pneumatic tool changer
The Fouk tool changer lets your workpiece switch tools in seconds—like changing grippers, welding torches, or other end effectors—using a standard interface. No complicated setup. No long downtime.
It helps your production line run more smoothly, reduces machine stoppage, and cuts down on manual work. The smallest model weighs only 0.4kg, it keeps the productlightweight while maintaining reliable performance.
2. Tool changer for light tasks and heavy-duty jobs with high torque
The crown pin locking system is built tough for real industrial use. It gives strong, stable connection every time, with a locking force range of 2500–31000 N to handle both light-duty and high-torque applications.
The electrical module is tested for over 1 million connections, so you can rely on it for long-term operation. When used with Amphenol connectors, plugging and unplugging becomes quick and easy—tool changes are fast and hassle-free. Suitable for robot payloads from 25–300 kg.
3. IP67 tool changer
Fouk robot automatic tool changer features a compact design—small size, low weight, but still strong and reliable. Supports electrical, pneumatic, and hydraulic modules, making it flexible for different needs.
With a protection level up to IP67, it effectively resists dust and water splashes, ensuring stable operation even in tough industrial environments.
Robot Tool Changer Selection and Configuration Example
Application Requirements
The application involves three different types of workpieces:
Short bar: Maximum weight 30 kg
Long bar: Maximum weight 50 kg
Disc-shaped workpiece: Maximum weight 40 kg
The robot needs to handle these workpieces using different grippers:
FR136 gripper for short bar handling
FR175 gripper for long bar handling
FZ160 gripper for disc-shaped workpiece handling
The grippers do not require sensors. When handling different types of workpieces, the robot needs to automatically change to the corresponding gripper.
The tool changer sensors must be PNP type.
Based on the above requirements, the suitable product configuration is selected as follows.
(1) Main Body Model Selection
Tool 1: FR136 Gripper + Short Bar Workpiece
Total payload calculation:
Workpiece weight + gripper weight + fingers weight
= 30 kg + 12.7 kg + 2 × 12 kg
= 66.7 kg
Tool 2: FR175 Gripper + Long Bar Workpiece
Total payload calculation:
= 50 kg + 27 kg + 2 × 18 kg
= 113 kg
Tool 3: FZ160 Gripper + Disc Workpiece
Total payload calculation:
= 40 kg + 10.5 kg + 3 × 6 kg
= 68.5 kg
Maximum Required Payload
The maximum payload among the three tools is:
113 kg
According to the product specifications:
Since:
100 kg < 113 kg < 150 kg
The selected model is:
QTC150 Robot Tool Changer
(2) Configuration Mode Selection
The robot needs to switch between three different grippers.
Therefore, the recommended configuration is:
1 Robot Side (M Plate) + 3 Tool Side (T Plates)
Configuration:
(3) Sensor Selection
The application requires PNP-type sensors.
According to Table 5.1 in the product manual, the QTC150 sensor configuration is as follows:
| Detection Function | Model | Quantity | Specification |
|---|
| Tool Changer Open/Close Detection | HS2-S04-P01 | 2 | PNP type, Normally Open (NO), 3-wire |
| Face Contact Detection | IPSD-2PS-0823-L3 | 1 | PNP type, Normally Open (NO), 3-wire |
(4) Pneumatic Module Selection
The pneumatic requirements for each gripper are:
FR136 gripper: 2 pneumatic circuits
FR175 gripper: 2 pneumatic circuits
FZ160 gripper: 2 pneumatic circuits
Total pneumatic circuit requirement:
2 + 2 + 2 = 6 circuits
According to Table 6.1:
QTC150 standard pneumatic pass-through:
9 × G3/8 ports
Since:
6 required circuits < 9 available circuits
No additional pneumatic module is required.
(5) Electrical Module Selection
The grippers do not use sensors.
Therefore:
No electrical module is required.
(6) Final Configuration List
| No. | Configuration Item | Model | Quantity | Remarks |
|---|
| 1 | Master Plate (M Plate) | QTC150-M | 1 |
|
| 2 | Tool Plate (T Plate) | QTC150-T | 3 |
|
| 3 | Open/Close Detection Sensor | HS2-S04-P01 | 2 | PNP type, Normally Open, 3-wire |
| 4 | Face Contact Detection Sensor | IPSD-2PS-0823-L3 | 1 | PNP type, Normally Open, 3-wire |
