2.2 UMC Zero Point Receiver - Installation

The dual zero point ready installation only needs to be done on machines that are ordering the 30kg RPL to be added to an existing machine. 

Note: For machines purchased with an RPL, the dual zero point ready is already installed on the machine. Skip this section if the machine already has the dual zero point ready kit installed.

This procedure applies to the following kits:

• 93-1001309 - Dual Zero Point Ready Kit UMC-1000
• 93-1001310 - Dual Zero Point Ready Kit UMC-750   
• 93-1001311 - Dual Zero Point Ready Kit UMC-500

The corresponding machine kit below will also need to be ordered to be able to do this procedure:

• 93-1001269 - RPL-30KG READY KIT UMC-500
• 93-1001270 - RPL-30KG READY KIT UMC-750
• 93-1001271 - RPL-30KG READY KIT UMC-1000

The purpose of the dual zero point ready kit is to allow for the pneumatics to be routed to the dual zero point clamp through the body of the tilt rotary. Installing this involves removing the platter and rotating the machine B-axis. Make sure this is possible before starting this procedure.

Note: The Robot Pallet Loader option also requires an auto window option to be installed. Refer to the UMC Auto Window - Installation - AD0663 to order and install this option on your machine.

Note: The only difference between these kits is the bottom cover panel for the TRT body on the different size machines.

Start by assembling the pneumatic manifold [1] that goes inside the C-body of the machine.

Attach each of the 2 ORB6M NPT 1/4" steel fittings [2] to a Brass 1/4" push connect fitting [3]. Once done, install each set of fittings onto the angeled ports on the manifold.

Tighten the last Brass 1/4" fitting [4] to the side port on the manifold.  

Install the 4 O-Ring 2-212 [5] into the grooves of the manifold. 

Connect the 3 Port Rotary Union Shaft to the 3 Port Rotary Union Shaft Extension using [2] SHCS 1/4-20 X 5/8 make sure the O-Ring 2-011 [1] are seated in the cavities of the shaft.

Torque the bolts to their required specs.

Press the dowel pin [1] into the anti-rotation block [2] until it bottoms out. 

Assemble the platter coupler [3] by placing the O-rings in position.

Place 3 of the 2-011 O-Rings [1] on the air ports shown in the image.

Place the larger 2-031 O-Ring [2] onto the middle groove of the coupler.

Rotate the B-axis +90 degrees and remove the cover [1]. Return the B-axis to its original position at 0 degrees.

This cover will be replaced by the cover included in the zero point ready field install kit.

Remove the platter by following the removal section of the UMC C-Axis Platter Replacement linked below.

 WARNING: IF YOU DO NOT DEPRESSURIZE THE SYSTEM BEFORE REMOVING THE PLATTER YOU CAN PERMANENTLY DAMAGE THE BRAKE BY REMOVING THE PLATTER.

Place the platter on a bench and bolt the coupler [1] to the platter using SHCS 1/4-20 X 5/8 [2].

While the platter is on the bench insert the felt strip included in the kit in the groove [3]

NOTE: If the UMC is not exchanging platters reuse the felt strip already in the groove. 

Torque the bolts to their required specs.

Install the coupler onto the shaft assembly [1] by using 1/4-20 X 1 1/4 bolts [3]. Make sure the O-Rings 2-011 [2] are in the cavaties of the shaft and not where the bolts attach.

Torque the bolts to their required specs.

Install the coupler and platter assembly [2] back onto the rotary using M12 bolts [1].

Tighten the bolts, but do not torque them down yet.

Follow the installation section of the UMC C-Axis Platter Replacement linked below for the full instruction on how to correctly re-install the platter.

Place 3 2-011 O-Rings [3] into the top of the coupler through the center bore in the platter.

The receiver is held in position by 4 T-nuts that are placed in the T-slots of the platter.

Use the 4 four bolts to fasten the pallet receiver [1] to the T-nuts [2]. 

Note: The spud is not shown in the image but should be located into the center bore in the platter. Make sure the ports on the spud align with the ports in the coupler when installing the dual zero point onto the platter.

Rotate the B-axis 90 degrees [1].

Attach the anti-rotation block [3] to the gearbox using the M6 bolts [4].

If the read head is in configuration [1] you will need to clock it to position [2]  this will require you to redo the compensations on the machine.

If the read head is in configuration [2] the compensations will not need to be redone.

Torque the bolts to their required specs.

Please contact service about borrowing a swivel checker.

Install the manifold assembly [2] from step 1 by inserting the anti-rotation dowel pin [1] into the pneumatic manifold.

After installing the shaft assembly to the pneumatic manifold make sure to install the snap ring [2] to the shaft groove [1].

Note: If the groove for the snap ring is not visible on the shaft, then some bolts may not be fully tightened, or the dowel pin needs to be pressed further into the manifold.

Close the air valve [1] at the bottom of the lube cabinet.

Bleed the remaining air out of the manifold by pulling on the air release [2]. Make sure the gauge on the manifold reads zero.

Install the Air Booster on the back of the machine using the magnets to attach it.

Route the zero point air lines through the black conduit that routes through the center bore and to the work holding manifold.

Route the opposite ends of the zero point air lines [1] to the Air Booster. 

Note: Make sure the hoses for the zero point are high pressure hoses.

Route the opposite end of the pallet air blast line [2] to the top of the lube cabinet. 

The unclamp hose denoted in green  [1] goes to the fittings as shown.

The clamp hose denoted in red [2] goes to the fitting as shown.

The air blast hose denoted in light gray [3] goes to the fitting as shown.

Connect the green hose to the unclamp port [1] of the solenoid denoted with a green zip tie on it.

Connect the red hose to the clamp port [2] of the solenoid denoted with a red zip tie on it.

Connect the air booster to the manifold [1] using the included HOSE 1/4 OD PE RED HIGH PRESSURE.

Connect the clear hose [2] for the Pallet Air Blast to the SOLENOID ASSY LS/AIR BLAST ZERO POINT.

This step is for machines with non-CAN lube panel:

Connect cable 33-1532 - Air Lube Solenoid cable to P35 on the IO PCB with the connector with the pigtail for Pallet Unclamp [16].

Route the cable to the lube panel to make the following connections to all the solenoid power cables. The color for each connector is listed:

[2] PulseJet Solenoid - White and Violet

[3] Auto Door  - Gray

[4] TRP Unclamp  - Yellow and Black

[5] Spindle Air - Violet

[6] Spindle Lube - White

[7] Min Lube Grease - White and Red

[8] Open Door Interlock - White and Brown

[9] Auto Air Gun (AAG) - Red

[10] TSC Purge - White and Orange and Yellow jumper to TAB Air [15]

[11] SMTC Pocket U/D - White and Black

[12] UMC Auto Window - White and Yellow

[13] Purge Solenoid - White and Gray

[14] Pallet Air Blast - White and Green

[15] Tool Air Blast Air (TAB) Yellow jumper from TSC Purge [10]

Connect cable 33-1307 CBL AIR VISE PRESS SWS PP ROBOT21FT to the pressure sensor as shown. 

Route the cable back to the I/O board and plug this into P13 using the adapter cable provided in the kit.

Note: The pressure sensor should be on the fitting where the red hose is connected. This sensor makes sure the zero point is clamped.

Connect cable 33-1306 to P36 [5] on the IO PCB. Connect the coolant refill to the pigtail if needed.

Route the other end directly to the Air Booster.

Connect the V-1 end [1] to the solenoid going to the zero point in the machine [4].

Connect the V-2 end [2] to the solenoid going to the load station zero point [3].

Reinstall the new cover [2] and return the rotary [1] to 0 degrees on the B axis.

After installing the Zero Point Receiver, MRZP needs to be done to account for the change in pallet height compared to the platter.

Assemble the zero point MRZP pallet [1].

Press the dowel pin [2] into the MRZP pallet.

Install the zero point pull stud [3] using the M10x20 SHCS [4].

Mount the MRZP artifact [5] to the zero point MRZP pallet using the 2 SHCS [6].

Go to the Recovery Page. Press [F2] [1] to unclamp the zero point pallet receiver [2] inside the machine.

Place the MRZP pallet assembly [3] with the artifact in the receiver. Make sure the dowel pin is aligned in the correct position.

Clamp the zero point receiver by pressing [F2] again.

Exit recovery and continue with doing MRZP. Refer to the UMC - MRZP and Safe zones page for more information on how to do MRZP.

Note: The center bore in the zero point calibration pallet can also be used for probing. The diameter of the center bore is 2 inches.

To test the clamp and unclamp of the zero point ready kit go to the Pallet Changer Recovery page.

Press [F2] [1] to unclamp the zero point pallet. 

Place a pallet [2] into the zero point receiver [3].

Note: Make sure that pallet is oriented correctly so that the dowel pin aligns with the zero point receiver.

Press [F2] again to clamp the zero point pallet.

Verify that the pallet is clamped to the receiver and that no alarms are generated.
