990-HQ Service Manual

Overview of the 990-HQ Door Hanging System

The 990-HQ entry door pre-hanging system produces machined doors with one or two cylindrical

locks and either three or four hinges attached to the door edge and hinge jamb. Hinges can be

mounted with or without hinge pins inserted.

In operation, the machine automatically adjusts to incoming door width and positions the door

against the appropriate index point for selected door swing and length, then clamps. Simultane-

ously an operator inserts a blank hinge jamb and clamps it in place with an electric foot-pedal.

Pressing a button starts the hinge routing and lock detailing sequence which takes less than 20

seconds including drilling screw holes for hinges as well as routing lock face plates. Afterwards

three 8 shooter screw guns gang feed screws and fasten three hinges. Overall cycle for a three

hinge doors produced one after another is less than 40 seconds even with two locks.

Doors requiring four hinges are processed with an extra step. After completion of the three hinge

sequence described above, the left or right routing head (depending on swing) will unclamp from

the door and jamb, then shift sideways to re-clamp and process a fourth hinge pocket. The direc-

tion of shift from the third hinge depends on door length, and will match Hume specifications of

approximately 100mm each direction. The gap between hinges is programmable. One eight

shooter screw-driving head is used to fasten the fourth hinge, and the door is automatically fed out

of the machine. Overall door to door cycle for four hinge units is less than 70 seconds.

Design features:

Lock Detailing: Includes a servo driven ball screw and programming to automatically position

and process one or two cylinder locks during the machine sequence. The touch screen panel pro-

vides multiple standard lock layouts or custom locations from the numeric key pad. The lock

machining mechanism includes heavy duty drill motors mounted above and below the door to

eliminate chipping door faces, a separate side drill for latch holes, and high frequency spindle

router for lock face plates.

Hinge Detailing: Three hinge heads, each with separate XYZ motion control to precisely rout and

drill hinge pockets in door and jamb. Each head has standard rotation spindle, reverse rotation

spindle, single point drill spindle and for corner square chisels. Motions are smooth and precise

with programming selected at the touch screen for a variety of hinge sizes and drill patterns,

including square hinges.

Hinge Locations: Each hinge head, jamb clamp fixture, door and jamb index stop and each screw-

driving heads is mounted on either 15mm or 25mm box bearings with ball screws and servo

motors to automatically adjust hinge locations to a variety of door and jamb sizes and positions

matching Hume specifications. Similar to lock locations, hinge layouts can be pre-programmed

and selected at the touch screen. The machine already includes 11 servo motor/ball screws for

lock and hinge processing. Adding programmable movements for machine adjustment adds 6

more: two for outside hinge heads, two for outside jamb clamps, two to adjust outside 8 shooters

to match heads.

Hinge attachment: three eight shooter screw guns are provided. Each unit is hydraulically driven

with ample power to drive screws even in hard-wood applications. Screws are fed eight a time

from an overhead sorting hopper down to the spring loaded guides. In operation, after placing a

hinge on the magnetic hinge blocks, pressing a button shifts the center and right guns laterally,

then all three guns travel downwards and index into “H” block fixtures at each hinge location, and

fasten the hinges simultaneously. A fourth hinge can be added afterwards as described earlier with

an extra hinge machining sequence. One hinge is placed on the appropriate screw-driving head

and sequenced to fasten the fourth hinge.

This machine is equipped with a solid state touch screen and industrial PC. The touch screen also

includes the capability to view the status of the various photo eyes and switches for quick diagno-

sis when needed, without having to open the electrical panel or for the operator to leave his work

station. The Touch Screen logic also includes management functions such as Daily and Lifetime

Totals. When connected to the internet, the PC allows remote support and monitoring of machine

functions from Kval in Petaluma, CA.

Door and jamb clamp reference: The door will clamp downwards rather than upwards and the

jamb reference will be to jamb stop (top of H block not staging block for jamb edge). This pro-

vides a consistent dimension between jamb weather strip and door face when the door is closed.

Minor variations in door thickness will be seen instead between the jamb edge and door face – a

thin door for instance will be spaced inside the frame slightly. Removable spacers will be fabri-

cated to insert in the top of each “H” block to compensate for jambs with weather stripping, or for

jambs without weather stripping, and to reference jambs with 38mm backset for 35mm doors.

Note: spacers will need to be chamfered on outside "H" blocks to protect weather stripping during

shift for fourth hinge.

teria to understand before operating the machine. It is highly recommended that personnel operat-

ing, working on a machine meet the criteria listed in this sheet. It is recommended the sheet be

signed and kept for records. See “Safety Sign-Off Sheet” on page 1-19.

Safety Terminology of Labels

In addition to the nameplate, KVAL machines may have other warning labels or decals that pro-

vide safety information to operators. Safety labels should be clearly visible to the operator and

must be replaced if missing, damaged, or illegible.

There are three types of warning labels or decals:

• DANGER means if the danger is not avoided, it will cause death or serious injury.

• WARNING means if the warning is not heeded, it can cause death or serious

injury.

• CAUTION means if the precaution is not taken, it may cause minor or moderate

injury.
