UMC Conveyor Spillway Extension - Installation

AD0565

Introduction

1

This procedure will explain how to install the chip conveyor spillway extension kits for the UMC Series Machines.

Use the following link to identify your conveyor. UMC CONVEYOR IDENTIFICATION

The kits come with components to help reduce chip overflow and reduce chip build up that can cause coolant blockage around the conveyor.

The components are for the following kits (Top Image):

  1. The Spillway
  2. The Mating Bracket
  3. The Wing Extensions

Service Kits:

Machines built before 06/01/2021 will order:

  • 93-3326 CHIP CONVEYOR KIT KEYARROW UMC 500
  • 93-3327 CHIP CONVEYOR KIT JORGENSON UMC-500
  • 93-3328 CHIP CONVEYOR KIT HENNIG UMC 500

The components are for the following kits (Bottom Image):    

      4. The Spillway

      5. Adapter Brackets (2x)

Service Kits:

Machines built before 02/24/2022 will order:

  • ­93-3921: CHIP EVAC KIT SHORT SPILL UMC-500

Machines built between 02/24/2022 and 10/15/2023 will order:

  • 93-3928: CHIP EVAC KIT LONG SPILL UMC-500..

 

NOTE: For servicing UMC-750/1000/1250/1500 Please refer to the following document AD-0732

 NOTE: For UMC-500's built before November 2019 the provided mating bracket [2] may interfere with the sheet metal. The original mating bracket [2] can be used in place of the new one.

 NOTE: For UMC-750/1000's built from October 2017 to February 2020 the spillway [1] may interfere with the enclosure. The original spillway [1] can be used in place of the new one.

 NOTE: The kit needed for the UMC-500 will depend on which conveyor brand is on the machine. For the UMC-750/1000 93-3409 will work for all brand conveyors. 

Installation

1

Remove the bolts attaching the conveyor to the enclosure [1].

2

Pull out the conveyor far enough so that the spillway can be removed and the mating bracket is exposed. 

3

Remove the spillway from the conveyor, it should start falling out when the conveyor is pulled out. Replace it with the spillway supplied in the kit [1].

4

With the wing exposed remove the 4 bolts holding the mating bracket to the conveyor. Replace it with the mating bracket supplied in the kit [1].

NOTE: The UMC-1000 does not use a mating bracket, this portion of the procedure only applies to the UMC-500/7500.

 

__________

For Service Kits:

  • 93-3921: CHIP EVAC KIT SHORT SPILL UMC-500
  • 93-3928: CHIP EVAC KIT LONG SPILL UMC-500 

Remove the adapter brackets currently on the machine and replace them the following way.

Bolt [1] the new adapter brackets [2] for the extended spillway loosely so that the spillway can be installed with ease.

5

The mating bracket for the UMC-500 will differ depending on which brand of conveyor is on the machine. Make sure the proper mating bracket is being installed according to the image:

  1. Keyarrow
  2. Jorgenson
  3. Hennig

NOTE: Machines that were made before 11/2019 may contain an older sheet metal that may interfere, if the sheet metal interferes contact Haas Service for further instructions. 

NOTE: 93-3409, CONV CHIP MANAGEMENT KIT UMC 750/1000, will have a mating bracket that fits all brands of conveyors for the UMC-750. 

__________

For Service Kits:

  • 93-3921: CHIP EVAC KIT SHORT SPILL UMC-500
  • 93-3928: CHIP EVAC KIT LONG SPILL UMC-500 

Loosely screw in 1/4 - 20 bolts to Drain Pan Spillway in both left and right sides shown in the second image. 

 

6

For Service Kits:

  • 93-3326 CHIP CONVEYOR KIT KEYARROW UMC 500
  • 93-3327 CHIP CONVEYOR KIT JORGENSON UMC-500
  • 93-3328 CHIP CONVEYOR KIT HENNIG UMC 500

Once the spillway and mating bracket have been replaced push the conveyor back inside the machine.

Do not bolt the brackets to the enclosure yet. 

 

 

 

 

 

 

__________

For Service Kits:

  • 93-3921: CHIP EVAC KIT SHORT SPILL UMC-500
  • 93-3928: CHIP EVAC KIT LONG SPILL UMC-500 

Mount the Adapter brackets onto the enclosure loosely with the conveyor in the machine. Insert the drain pan onto the ¼ bolts from the previous step.

Align the pan laterally with respect to the spill way. Tighten the upper bolts on both sides.

The edge of the drain pan must be aligned just below the spillway edge, indicated by the arrows, to allow for adequate chip flow but not below the end of the casting.

The lower flange of the drain pan should be in contact with the base’s spillway.  

7

With the conveyor in the machine have someone push on the conveyor to create a gap between the conveyor and the casting.

Insert wing brackets [1] between the top of the conveyor and the casting. make sure the shoulder of the mating bracket is against the wing brackets.  

With the brackets in place install self tapping screws at the TOP of the slots in the brackets. This will allow you to bring the brackets upward to meet the casting if necessary. 

NOTE: Make sure the bracket is wedged between the casting and conveyor to create a seal so chips do not leak through the gaps.

8

Reinstall the bolts attaching the conveyor to the enclosure [1].
