CRG 30

Collaborative gripper with IO-Link

For the collaborative use, Weiss Robotics offers with the CRG 30 a compact servo-electric gripping module with integrated control and IO-Link, which is particularly suitable for small parts handling. The CRG 30 gripper has an integrated gripping force unit with an absolute measuring system, which prevents the workpiece from falling out when the power supply is interrupted.

Collaborative gripper

Teamworker

The CRG 30 has been spe­ci­al­ly deve­lo­ped for the col­la­bo­ra­ti­on of humans and robots. Roun­ded edges and safe grip­ping force make the CRG 30 a fle­xi­ble tool for col­la­bo­ra­ti­ve robots, which alre­ady meets the DGUV recom­men­da­ti­ons for col­la­bo­ra­ti­ve robotic sys­tems as well as the requi­re­ments of the ISO / TS 15066 stan­dard. This great­ly sim­pli­fies the risk assess­ment of your col­la­bo­ra­ti­ve robot app­li­ca­ti­on and let you reach your goals fas­ter.

Sensorless gripping force control

Sensitive gripping

With the sen­sor­less force con­trol, the CRG 30 also hand­les britt­le, fra­gi­le or com­pli­ant parts effort­less­ly and ensu­res a con­sistent­ly repro­du­ci­ble grip result. Using sta­te-of-the-art model-based algo­rithms, the cur­rent grip­ping force from the dri­ve sta­te is deter­mi­ned and con­trol­led to the pre­de­ter­mi­ned value. This tech­ni­que gua­ran­tees a repro­du­ci­ble grip­ping result even under chan­ging ambi­ent con­di­ti­ons. Both the grip­ping ran­ge and the grip­ping force can be fle­xi­b­ly defi­ned for each grip and thus opti­mal­ly matched to the grip­ping part. In addi­ti­on, the CRG 30 sup­ports pre­de­fi­ned grip con­fi­gu­ra­ti­ons, which can be easi­ly selec­ted by the sys­tem con­trol­ler.

Communication via IO-Link

Good connections

Para­me­te­ri­za­ti­on and con­trol of the CRG 30 grip­per are car­ri­ed out using the wide­ly used indus­tri­al stan­dard IO-Link. This crea­tes fle­xi­bi­li­ty, becau­se IO-Link not only sim­pli­fies the con­nec­tion to the pro­cess con­trol, but also faci­li­ta­tes the para­me­te­ri­za­ti­on and dia­gno­sis in the plant via a stan­dar­di­zed pro­to­col. This way, you always have your pro­cess under con­trol.

Gripping part detection integrated

Forget external proximity switches!

The CRG 30 has a built-in grip­ping con­trol with grip­ping part detec­tion and grip moni­to­ring. This ensu­res safe hand­ling even in dif­fi­cult situa­ti­ons. Thanks to its pre­cise ser­vo-elec­tric dri­ve, the jaws can be fle­xi­b­ly pre-posi­tio­ned and thus dif­fe­rent work­pie­ces can be grip­ped without retoo­ling. The other­wi­se necessa­ry exter­nal sen­sors are not requi­red, which mini­mi­zes the inter­fe­ring con­tour of the grip­per and con­s­i­der­ab­ly increa­ses the pro­cess relia­bi­li­ty.

Position measuring system

Absolute precision

With the new abso­lu­te mea­su­ring sys­tem, the CRG 30 knows its fin­ger posi­ti­on during start­up even without a refe­rence move­ment. This allows you to sim­ply con­ti­nue the grip­ping pro­cess, even if the ope­ra­ting vol­ta­ge has been inter­rup­ted by an emer­gen­cy stop or a restart of the sys­tem pro­gram.

Reliable technology

Made in Germany

With the CRG 30, you rely on the hig­hest qua­li­ty and sta­te-of-the-art tech­no­lo­gy. The main­ten­an­ce-free and fric­tion-free rol­ler bea­ring gui­des with FDA-com­pli­ant lub­ri­ca­ti­on make the grip­pers very robust and enab­le pre­cise and sen­si­ti­ve grip­ping over the ent­i­re stro­ke. Due to the uni­que dou­ble bea­ring of the base jaws, the grip­ping force is almost inde­pen­dent of the fin­ger length. The main­ten­an­ce-free brush­less DC motor pro­vi­des a high agi­li­ty and gua­ran­tees a long life­time.
