Un servomoteur entraîne la vis à billes par l'intermédiaire d'une courroie crantée, qui déplace linéairement les mors de base reliées aux écrous de broche et aux patins à profilé.

Individually configurable stroke
The stroke per jaw can be configured to customer specifications between 100 mm and 400 mm per jaw with millimeter precision. (For size 10, the stroke is limited to 300 mm)

Finger version
The gripper is available in two finger versions. In addition to the basic variant for short finger lengths, a variant with a long finger length can also be configured for corresponding applications.

-
Short finger length with two guiding carriages per base jaw
- 2
-
Long finger length with four guiding carriages per base jaw
Synchronization
The gripper can be configured as a synchronous and asynchronous variant. In the synchronous variant, the two base jaws are jointly controlled by a servomotor, with the jaw movement being synchronized by a counter-rotating ball screw. With the asynchronous variant, the two base jaws can be controlled independently and separately from each other. In this variant, one base jaw each is connected to one of the two required servomotors via the ball screw and the toothed belt.

Gripper mounting
The gripper offers different options for mounting on robots or gantries.

Adapter plate, complete (gripper side + blank)
- 3
-
Adapter plate, complete for screw connection according to EN ISO 9409
Position clamping
The electric holding brake prevents the movement of the ball screw, thereby clamping the position of the base jaws. Two brakes are required for the asynchronous variant. One fast switching module (ROBA®-brake-checker) is required for each holding brake (ROBA-stop®). This is included in the scope of delivery of the gripper.

Lateral mounting options
Optional mounting options on the gripper for customized additional attachments such as cameras, sensor distributors or blow-out nozzles. This option cannot be combined with the "weight-optimized design" option.

重量最適化
側壁を切り抜いたことで、グリッパーの重量を最大15％削減しました。このオプションは、オプション「側面取り付けオプション」と組み合わせることはできません。

カバープレート
カバープレートで、アタッチメント側のグリッパーを閉じます。これにより、グリッパーを外的な影響を受けないようにすることができます。それに伴い、モーターは接続が切断されます。
