DESAUW® DeSawyer 2000


Since you may not be immediately aware of the DeSawyer 2000's features & operation, we would like to provide you with an overview of the first and only computerized, five-bladed component saw with a completely manual backup system.

The DeSawyer 2000 combines the versatility of the DeSauw design with the efficiency of automation. The DeSawyer 2000 will setup faster, maintain accuracy, live longer, and give you a better return on your saw investment than any other component saw available, worldwide!

II. DeSawyer 2000 Operation

A. Three operating modes:

1. Automatic Mode, Download Operation
  1. Every movement of the saw is automated through the computer; including the hold-downs¡¦ position, resetting the lumber counter, setting the lumber stop and board length and, of course, all blade positions.
  2. Download setups from LAN or diskette, The DeSawyer 2000 is designed to accept files through either a LAN, whereby a direct link is established to the engineering office, or by inserting a floppy disk into the saw to download files. Job files are sent into the DeSawyer 2000's onboard computer and made available to the sawyer through the Job List. This, of course, is a paperless system providing clear and concise job data, and does not require a printed cutting bill.

  1. The onboard computer provides a logical order of events for completing a downloaded setup. The DeSawyer 2000 applies each setup to its operating parameters and determines the best way to make the cut. If a particular cut cannot be made due to the safety limitations of the automated movements, the sawyer is notified immediately and is given the option to setup in the semi-auto mode. It doesn't allow the sawyer to waste precious time attempting setups that are unachievable.
  2. The sawyer may randomly choose any job, or piece to cut, by highlighting a setup on the list provided in the Automatic Job List. In addition, he may view each individual board within that job; identifying nominal length and grade needed to complete the component. This information may also be made available to the material picker for adequately supplying nominal lengths and grades to the DeSawyer 2000.
  3. Two diagrams of each piece are displayed. One display shows the relative shape of the setup, including the angles at either end of the board. The other shows the board shape again, including the lengths involved in completing the setup. These include the topside, centerline, bottom-side, length of cuts, and overall length of the component.
  4. Make a setup by Highlighting a Piece and pressing the [START SAW SETUP] field on the touch screen display.
  5. Setups are made directly from the saws current configuration. It does not travel back to a home position between setups. Setup times are minimized proportionately to the degree of variance between the current piece and the new piece being set up.
  6. The DeSawyer 2000 has a Manual Sequencing feature. Upon completion of the required number of pieces in the current setup, the DeSawyer 2000 notifies the operator and prompts him to shut down the blades. It then requires a new selection to be highlighted and started to advance to a new setup. There are two reasons for operating this way:
    (a) He may shut down the blades and make a new setup,
    (b) He may continue to cut additional pieces with the current setup,
    In either instance, the blades are stopped, while the setup is performed. We have chosen to include this method of operation, so that the operator may verify all safety requirements are met prior to manually starting the blades.

2. Semi- Auto, Touch Screen Setup Entry

  1. All 5 Blades, Hold-downs, Lumber Stop, and carriage, etc. are returned to specific places for verification of accuracy

3. Manual Mode, Backup Pushbutton Operation
a) Maintains Complete Functionality of All Movements via push button switches
b) Angulations are verified with Mechanical Counters (Indicator shows position to 1/10th of a degree) and frame scales are used to position blades.

c) When other saws experience a computer problem, their cutting stops! In a similar scenario, the DeSawyer 2000 will continue cutting components in the manual mode. The DeSawyer 2000 is the only fully automated component saw of its kind that will operate with the computer, or the PLCs disconnected.

B. Productivity Tracking

1. Monet's software accurately collects and records data from the time a sawyer begins operating the saw, and his production throughout the shift.
a) The sawyer logs into the computer by name at the beginning of the shift, and records his breaks, lunch, and meetings, etc.
b) Each job is given a time stamp and recorded. At the end of the shift, this data may be sent to a printer for management purposes.

2. The DeSawyer 2000 comes with a Production report monitoring software.

C. Self-Diagnostic Maintenance Monitor detects most electrical problems and proposes a solution.

1. Each functioning area of the saw is listed on one of three Maintenance Screens with a corresponding colored bullet, which indicates the status of the functioning areas of the saw.
a) A green bullet indicates that area is functioning properly.
b) When an item has a red bullet, this indicates the saw detects a problem with that respective function and is attempting to recommend the most likely solution.

D. Add On Features

1. Backside Screen Display An additional screen display on the backside of the saw is available for increasing communication between the sawyer and catcher.
(1) This monitor displays information to the catcher in real-time, just as the sawyer is operating and navigating the program.
(a) He may identify the boards moving through the saw, by the highlighted setup on the screen allowing him to function independently from the sawyer.
(b) Catcher gains exposure to the operating system, and becomes familiar with its operation.

III. Board Marking Systems

A. Ink Jet Marking Systems

1. Relatively inexpensive initially as far as marking systems are concerned, but requires replenishing consumable ink supply, daily purging & cleaning, stocking replacement nozzles, and rebuilding spray heads on a regular basis. Other considerations include damp wood applications, and conveyor speed regulation.

B. Laser Marking Systems

1. Pricey initially, but equals approximate operating costs throughout 5 yr. period with inkjet. Somewhat Maintenance-free equipment.

IV. Ensuring a Smooth Transition

A. Upon installation, our technicians and staff will provide adequate training to ensure proper operation and maintenance required of your DeSawyer 2000.

1. We will verify the transfer of data between the engineering office and the DeSawyer 2000 is operating correctly and that files are downloading. If you have a special software application other than the known plate suppliers engineering, we will assist in compatibility issues.

2. Upon installation, we will verify that your sawyers are competent with each of the three operating modes. We will also verify that they understand when to use each mode. We will verify they can operate the saw in the manual, push-button mode, the touch screen semiautomatic mode, and the fully automatic, download operation mode. We will verify they are familiar with the self-diagnostic system and the Maintenance Mode.

We would like to assure you that the DeSawyer 2000 is manufactured with Quality!
We invite you to begin realizing the advantages of using the DeSawyer 2000.
