This further decreases the opening and closing time of the gripper.

5 HS GRIPPING FORCE The graphs show the gripping force on each jaw, as a function of the operating pressure, of the gripper finger length (Z) and of the overhanging of the gripping point (X). The force shown in these graphs refers to one jaw. The total force is double. GRIPPING FORCE N x = lbf PRESSURE bar x 14.5 = psi opening closing opening closing (87 psi) (87 psi) Gripping Force Gripping Force Fx s 80 N 150 N Fy s 60 N 100 N Mx s 4 Nm 8 Nm My s 4 Nm 8 Nm Mz s 4 Nm 8 Nm Fx d 1 N 2 N Fy d 1 N 2 N Mx d 4 Ncm 8 Ncm My d 4 Ncm 8 Ncm Mz d 4 Ncm 8 Ncm m 50 g 100 g opening Gripping Force Gripping Force closing opening (87 psi) closing (87 psi) SAFETY LOADS Check the table for maximum permitted loads. Excessive forces or torques can damage the gripper, cause malfunctions and endanger the safety of the operator. Fx s, Fy s, Mx s, My s, Mz s, are the maximum permitted loads under static conditions when the jaws are not moving. Fx d, Fy d, Mx d, My d, Mz d, are the maximum permitted loads under dynamic conditions when the jaws are moving. m is the maximum permitted weight of each gripper finger, when the gripper is used without speed adjustment. If the weight of the fingers exceeds the permitted value, it is necessary to decrease the speed of the jaws by using flow controllers (not supplied). 212

6 by HS GRIPPER MOUNTING The gripper can be mounted to a static or a moving part. When on a moving part, attention must be paid to the inertial force which the gripper and its load are subjected to. To mount the gripper use: the two tapped holes (A) and the two dowel pin holes (B) on the side of the gripper body; or the two tapped holes (A) and the two dowel pin holes (B) on the bottom of the gripper body; In the latter case, allow room (E) for the sensors. A M4 x 6 mm M4 x 8 mm B Ø3H8 x 6 mm Ø4H8 x 6.5 mm E 4 mm 5 mm MOUNTING GRIPPER FINGERS The fingers must be as short and light as possible. Fit them to the jaws by centering the calibrated profile (D) and locking with a screw through the middle threaded hole (C). C M5 x 7.5 mm M5 x 9 mm D x mm x mm 213

7 HS SENSORS The operating position is detected by one or more magnetic proximity sensors (optional) through a magnet placed on the piston. Magnetic proximity sensors should not be used in the vicinity of large masses of ferromagnetic material or intense magnetic fields as this may cause detection problems and jeopardize proper operation. The sensors that can be used are: OUT PNP Magneto-resistive SS... NPN SS OUT SS4N225Y PNP 2.5m cable $26.14 SS4M225Y NPN 2.5m cable $26.14 SS3N203Y PNP M8 snap plug connector $29.96 SS3M203Y NPN M8 snap plug connector $29.96 They are all provided with a flat three-wire cable and a LED. 214 SS... + SS

by HS PIPING THE UNIT The gripper is pressurized from the side ports (P and R) using proper fittings and tubing (not supplied). Compressed air in P: gripper opening.

8 by HS PIPING THE UNIT The gripper is pressurized from the side ports (P and R) using proper fittings and tubing (not supplied). Compressed air in P: gripper opening. Compressed air in R: gripper closing. The compressed air must be filtered using a 5 to 40 micorn filter. The initial choice on air lubrication (lubricated or not) must be kept for the entire service life of the gripper. The pneumatic circuit must be pressurized progressively to avoid uncontrolled movements. R P PNEUMATIC CIRCUIT Possible problems on a compressed air circuit: 1- Pressure variations. 2- Pressurizing the empty gripper at start-up. 3- Sudden lack of pressure. 4- Excessive drive speed. Possible solutions to the above issues: 1- External compressed air storage (A). 2- Start-up valve (B). 3- Safety valves (C). 4- Flow controllers (D). 215

9 HS CAUTION Never let the gripper come into contact with corrosive substances, powders, or soldering or welding spatter as they will damage the gripper. Never let non-authorized persons or objects be within the operating range of the gripper. Never operate the gripper on a machine that does not comply with the safety standards and laws of your country. MAINTENANCE The gripper must be lubricated every 30 million cycles, using the following products: Molykote DX (metal parts). Molykote PG75 (gaskets). The figure below shows the jaw backlash. 216
