Overview of the Endeavor System

Central Operator’s Station

A central computer and KvalCAM software to is used to operate the

entire door line. Door file creation software is included and allows

locks, lights, viewers and edge detailing to be combined into a single

door file referenced from the screen, a bar-code label or (optional)

chip embedded in the door . Extensive machine diagnostics are

included, as well as internet support and connectivity for remote sup-

port via our offices in Petaluma.

ON-3 Feeder

The KVAL ON-3 Door Feeder automatically lifts individual doors from a

stack up to 7 feet high and places the door onto a powered roll table

where the door can be fed to the next machine manually with a

'Call Door' switch or automatically fed when the next machine

in the line is ready to receive a door. Cycle time is approxi-

mately 20 seconds.

The door stacking mechanisms are based on a standard KVAL

ON-3 Door Stacker which includes a power roll conveyor and

pick and place door lift, but using Schmalz vacuum platens rather

than the standard end gripper.

Wire guards are attached to the ON-3 frame on three sides. A slot opening

will be provided to allow the door to be fed to the next machine. (Optional)

Note: Minimum ceiling height required for clearance for the

clamp assembly is at maximum

Maximum door stack height will be 84".

A variable speed drive is installed, with controls, to match the feed speed of the machine line.

KVAL Service Manual

DL-NCD and Invert Station

The DL-NCD is a Numerically-Controlled Door Light Cut-Out Machine

equipped with AC servo control for all three axes of cutting, ‘X’ (Length

of the door), ‘Y’ (width of the door), and ‘Z’ (Depth into the face

of the door). The ‘Z’ axis servo control makes it simple to

program for security locks where the face bore is

machined to a precise depth. The operator may

reduce the plunge speed to minimize tear-out in the

bottom face when machining small diameter holes.

When the DL-NCD is used as a drill, de-burring on the

bottom face may be required.

The DL-NCD is equipped with an automatic feed and width

adjust system to automatically receive doors, position the door

against the stop, clamp the door and start the machining sequence if

the instructions have been downloaded. The DL-NCD can process doors

that vary in height from 6’-6” to 8’-0”, 12” to 3’-6” in width and 1-3/4” in

thickness. Minimum distance from edge of cutout to edge of door is 1-1/2" on both

sides.

The direct drive high frequency spindle motor for cutting the door is equipped with an automatic

tool changer and access to eight (8) additional tool holders which are placed in a fixture along the

fixed side of the machine. Programs can call for an automatic tool change and RPM adjustment

for wood, fiberglass or steel doors. Individual door light patterns are created at the machine con-

sole, or remotely using a standard PC. The DL-NCD includes an industrial PC with a standard

Ethernet connection for file transfer and library backup, as well as occasional internet support and

updates from KVAL.

All DL-NCD installations require that the integrated PC computer has access to broadband inter-

net for real-time diagnostics and program updates. On-board diagnostic programs allow the user

to determine the source of operating errors and failures, even after they have occurred. A tool

holder stand and torque wrench are included so tool changes may be done quickly and accurately.

STANDARD ORIENTATION: Standing at the fixed fence, the DL-NCD feeds from left to right.

Entry doors are oriented sill end leading, with the lock side against the fixed fence. Doors are usu-

ally aligned so the lock side of the door is against the fixed fence to ensure the lock bore backset

is accurate.

Overview of the Endeavor System

KVAL Service Manual

Automatic Door Invert Station (Option for DL-NCD)

A fully automatic door station designed to invert door slabs after the

DL-NCD door processor. After auto in-feed with powered

rolls, the door is inverted sideways and realigned for

reverse feed back into the DL-NCD.

Endeavor

The ENDEAVOR is a fully automatic computer controlled door

machine capable of simultaneously routing both the lock stile

and hinge stile. Corner squaring chisels are standard for hinge

pockets and lock face plates. Pilot hole drilling is also

standard for hinges, and is available as an option

for lock face plates.

Machine orientation allows the

Endeavor to work directly in line with the

KVAL DL-NCD: The lock side is fixed

while the hinge side adjusts to match door

width.

Normally door specifications are automatically

transferred to the machine’s computer just as a door

enters from a KVAL DL-NCD, so no operator intervention

is required. All functions are automatic including adjustment

for door thickness, width, length, door positioning, setting head angle at 0 degree or 3

degree, clamping, and detection of exact door top location on both lock stile and hinge stile. The

automatic cycle includes all machining operations, followed by unclamp and out-feed.

For the lock side, the machining carriage features three heavy duty three phase spindle routers: a

12HP motor for mortise lock and cylinder bores, and two 7-1/2 HP motors, with one motor with

left had rotation and the second motor with right hand rotation to process hardware templates

requiring routing through the top or bottom door faces – such as T strikes, or through the stile end

for an auto flush bolt. The entire head pivots from zero to three degrees on precision Timken bear-

ings as part of the automatic sequence.

Overview of the Endeavor System

1-5

KVAL Service Manual

The lock carriage X axis travel is 122", the Y axis travel is 20" and Z axis travel is

9-1/2". Feed speeds up to 2400 inches per minute can be programmed. This 'X' axis travel allows

the head to machine the full length of the lock stile for top and bottom flush bolts or multi-point

lock hardware on a 10'-0" door.

For hinge side machining, two additional independent carriages simultaneously process hinge

mortises while the lock is being detailed. Each carriage includes two heavy duty 3 HP 3 phase

high frequency motors which also pivot either for 0 or 3 degree bevel, again with precision Tim-

ken bearings. One motor is right hand rotation and the second motor is left hand rotation. The

computer automatically selects the proper motor to cut into the door to eliminate chip-out and

then switches to the second motor to prevent chip-out at the other end of the hinge. Programming

is available for Soss hinges and intermediate pivots.

Each hinge routing carriage also includes a pre-drilling motor for hinge screws and corner squar-

ing chisels for square hinges. The pre-drill motor on each carriage is a high frequency 23,000

RPM spindle equipped with a quick change chuck. Programmed drill motion processes pilot holes

in succession for a variety of hinge sizes. The corner squaring chisels can be selected to automati-

cally square the corners of hinge pockets machined with a 1/2" router bit.

Almost any combination of hinge spacing can be easily programmed with both carriages simulta-

neously machining two hinge pockets and automatically machining the third pocket, or fourth

pocket, in a second operation. Typical overall cycle time for doors with four hinges, squared and

drilled for screws, and including lock detailing for either a cylinder or mortise lock will be under

sixty seconds door to door. The cycle will be slightly higher when door width changes, and up to

twice as long for doors with a T strike combined with a top and bottom flush bolt.

ON-3 Stacker (Option TD)

This station combines the functions of a door stacker with a packaging

machine, dispensing and cutting two strips of polyethylene foam

between each door. Foam width is assumed to be approximately

4”.

The door stacking mechanisms are based on a standard

KVAL ON3 Door Stacker which includes a power roll con-

veyor and pick and place door lift, but using Schmalz vac-

uum platens rather than the standard end gripper. The

vacuum system avoids gripping clamps on the door ends

that conflict with the foam dispensers, and eliminates prob-

lems with door positioning when door width varies. Doors

are lifted from the conveyer, then lowered and stacked along-

side the outside of the conveyor.

This version adds mechanism and programming to automatically lay

two strips of polyethylene foam as each door is stacked, automatically

adjusting foam positions to the door width, so strips are consistently located along the outside

of the door face.

All doors regardless of length will be stacked flush to one end towards the off-feed end of the

power conveyor. Door width is also stacked flush along one edge. Foam length will be auto-

matically determined based on the length of the next door waiting to be stacked. If a longer

door is stacked above a shorter door then excess tape will be cut to avoid mechanical conflict

between the foam strip pulling shuttle and the next door.

For simplicity, a heavy duty scissor lift is also incorporated in the design so each door is stacked at

a fixed height. The lift lowers by one door thickness each time a new door is added to the stack.

This eliminates the need raise and lower the roll dispensers, foam clamps, hot knives and the foam

strip pulling shuttle. It is also assumed that door stacks will be no more than 40 doors high.

The foam dispensing system is very similar in design to the newest Esse 2 packaging machine at

Wausau Supply, but with two dispensers to lay two strips. The inside strip, closest to the power

conveyor frame work is fixed in position aligned with the fixed long edge of the door stack. The

outside roll assembly will auto adjust to agree with the next door on the conveyor if the next door

is the same width or wider, but if the next is narrower, then the tape will be applied inwards to

support the narrow door about to be stacked.returns across the door pulling foam from the reels,

then stopping just beyond the door end. The next door is lowered on top of the foam, and while it

remains under tension, the hot knives cut the foam to length – and the cycle repeats.

After a door is placed on the stack, and the vacuum lifter returns above the conveyor, a foam

clamp shuttle will move from the far end of the door stack across the door of the ends of foam

tape clamped just inside the hot knives. This movement is via servo motor control and Brecoflex

belting, supported on precision rail bearings on the outside face of the conveyor table framework.

The tape ends are clamped, and the shuttle
