Installing the vacuum valve set 3-64
The installation procedure is detailed below.
1) Move the J3 axis to the top end with a jog operation and shut off the controller's power supply. This is
necessary for space standard settings when feeding the air hose and hand input cable through the inside of
the shaft.
2) Remove the screws fixing the No. 2 arm cover U, and remove the No. 2 arm cover U.
3) Fix the vacuum valve to the mounting bracket in the position indicated in
. Place it so that the vac
-
uum valve's primary piping connection joints (PV, PS, V ports) are located on the right hand side, and fix it
securely using the attachment M4 screws (tightening torque: 1.39 to 1.89N ・ m).
When using a 2 sets vacuum valve, two vacuum valves are jointly fastened to the mounting bracket with
screws.
4) Connect supplied cables and air hoses. The cables are connected to the vacuum valve by using the following
connector.
1 set: connector S1 and V1
2 sets: connector of S1, S2, V1, and V2
5) Connect the hand input/output signal connection connectors (GR1, HC1, and HC2) of the vacuum valve
with hand input/output signal connection connectors of robot arm side (GR1, HC1, and HC2). Connect with
the same names.
The hand output signal cables of the robot arm side are located close to where the vacuum valve is
installed and are tied up with cable tie. Pull out and connect them to the connectors.
6) Connect the primary piping air hose (φ6). The air hoses are located close to where the vacuum valve is
installed and are tied up with cable tie. Cut the cable tie and connect them. Of the two air hoses, connect
the one marked “AIR IN” to the vacuum valve's PS port, and the one marked “RETURN” to the PV port.
7) Connect the secondary piping air hose (φ4).
8) Pass the secondary piping air hose through the shaft.
9) The silicon rubber is supplied together with the vacuum valve to prevent bending the air hose. Wrap a sec
-
ondary piping air hose in the silicon rubber and fix them with supplied cable tie at (b) portion shown in
.
10) Carry out piping on the tool side.
Fix the air hose to the hand side. Check again that the highest point of the
curved section of the air hose reaches the height of the fixing plate upper end,
and then fix the air hose at the tool side. If the air hose is not long enough or
too long, when the robot operates, excessive bending and friction with the shaft
upper end or the cover may result in a break or abnormal operations of the tool
(hand).
11) Apply silicon grease to the contact surface between the air hose of the fixing plate, the air hose sliding
portion from the shaft upper end to the fixed portion, and the opening on the shaft upper end.
12) If the air hose have excess length, fix the excess section of the air hose at the plate with the cable tie.
13) Power on the controller, perform the jog operation for the J3 and J4 axes, and check that the air hose do
not interfere with other components.
14) Turn off the controller’s power supply, then install the No.2 arm cover U securely as before with fixing
screws (tightening torque: 1.39 to 1.89 Nm).
Note) The installation surface of the cover is using sealing material. In the event that the sealing mate
-
rial has been removed or has been bent or broken to the extent that it cannot be return to the
original form, be sure to replace the sealing material. Please contact dealer when the sealing
material needs to be replaced.
The installing of the solenoid valve set is completed.
