By applying pressure to the opposing drive pistons, the multi-tooth guided base jaws are directly driven via a drive type fastening. The jaw stroke is synchronized by means of rack-and-pinion kinematics. This ensures powerful and centric opening and closing of the gripper.

Gripping force maintenance version AS/IS
Conventional gripping force maintenance via springs also ensures a minimum gripping force in case of a pressure drop. In the AS variant this acts as a closing force, and in the IS variant as an opening force. The image shows the AS variant. The gripping force maintenance can also be used to increase the gripping force or for single actuated gripping.

Gripping force maintenance by means of a pressure spring
Conventional gripping force maintenance via springs also ensures a minimum gripping force in case of a pressure drop. In the AS variant this acts as a closing force, and in the IS variant as an opening force. The image shows the AS variant. The gripping force maintenance can also be used to increase the gripping force or for single actuated gripping.
GripGuard: secure, certified gripping force maintenance version ASC/ISC
Secure GripGuard gripping force maintenance also ensures a permanent min. gripping force of 80%, even in case of a pressure drop. In the ASC variant this acts as a closing force, in the ISC variant as an opening force. Compared to conventional gripping force maintenance via springs, this GripGuard variant thereby ensures a significantly higher gripping force. In addition, the gripping force maintenance is constant over the entire jaw stroke. There is also no risk of injury with this gripper, as the base jaws do not move uncontrollably in the event of pressure drop. This simplifies the risk assessment, since gripping force maintenance is already certified as a safety function (PLd Cat. 3).

Pinion shaft
The one-piece pinion shaft connects the pinion of the jaw synchronization with the mechanics of safe gripping force maintenance. - 8
-
Clamping element
In the event of a pressure drop where a workpiece is not gripped, the clamping element will prevent the pinion from rotating. This prevents any potentially dangerous movements of the gripper fingers. - 9
-
Elastomer
In the event of a pressure drop while gripping the workpiece, the gripping force accumulated in the elastomer (energy storage) will retain the workpiece securely. The clamping element prevents the gripper fingers from opening in such cases. - 10
-
Spring-loaded pneumatic piston
In normal gripper operation, the pneumatic piston is always actuated with compressed air. This does not require a separate air supply. In the event of a malfunction, i.e. a sudden pressure drop, the piston is pushed back via the spring assembly and the clamping element blocks the pinion shaft so that movement of the gripper fingers is no longer possible - 11
-
Pressure compensating valve
The pressure compensation valve ensures any excess pressure that has accumulated inside can escape to the outside. At the same time, it prevents dirt or liquids from entering the inside from the outside.
Certified gripping force maintenance
The certificate was issued by the German Social Accident Insurance (DGUV). The DGUV test certificate confirms the secure GripGuard gripping force maintenance in case of a power failure for the gripper series PGL-plus-P in the versions ASC and ISC. The gripping systems comply with the relevant provisions of Directive 2006/42/EC (Machinery Directive). The safety function is implemented with category 3 and PLd according to EN ISO 13849-1:2015.
Integrated sensor system IOL
The gripper variant "IOL" with integrated sensor system enables precise and process-reliable monitoring of the complete gripper stroke via IO-Link. There is no longer any need for separate procurement, installation and adjustment of additional, externally mounted sensors. In addition to IO-Link standards such as temperature display and process parameters, this integrated sensor system offers two additional modes as standard that are perfectly tailored to gripping applications: Gripping Point Mode and Gripping Range Mode. Up to eight workpieces (positions or ranges) can be stored directly in the sensor profile. Tolerance and hysteresis values are already stored in the sensor profile, but can be set individually if required. However, due to the default values, this is not necessary in most cases.
使用磁性传感器的外部传感器系统
机械手已配备两个传感器插槽,用于安装磁性传感器。用户可选择不同的传感器:单点式、多点式或其他可装于 C 型槽的紧凑型模拟量传感器。该图显示了采用两个 MMS 22 传感器进行 “机械手打开” 和 “机械手关闭” 位置查询。
使用感应式接近传感器的外部传感器系统
“IN” 型机械手随附两个感应接近开关的预装套件。已预设“机械手打开” 和 “机械手关闭” 两个位置。必须分别订购接近开关,并将其插入外壳滑槽,直至到达止挡并被夹持住。两个传感器均可单独设置以监控任何位置,例如“工件被抓取”。此外,还可以在机械手背面额外安装两个感应接近开关的连接件,这样总共可安装四个传感器。
精密型号 P
对于 “P” 精密型机械手,基爪在完全组装好的机械手上进行了再加工。通过此方式能够补偿与公差相关的偏差,并实现精确定位、塑型和位置公差。可适用高精度的抓取应用或极为精确机械手更换,无需重新对准。
定制化附件的可选安装选项
在机械手顶部,还有四个螺纹和安装件可供选择。如有需要,它们可用于固定其他定制化的配件或实现额外功能。该图显示了采用额外定心或工件支撑的应用示例。

Kromě běžných manipulačních procesů lze k držení obrobků během jednoduchých obráběcích operací použít také robustní univerzální chapadlo PGL-plus-P chráněné proti nečistotám. Ve znázorněném příkladu je obrobek držen mezi uchopovacími prsty. Robot pohybuje obrobkem podél stackonárního odjehlovacího vřetena pro odjehlení. Připojený závěrný vzduch zabraňuje proniknutí nečistot do chapadla.
