label for every package on the conveyor. Finally, these
requirements effectively limit the speed with which packages
can be conveyed past the labeling station.
SUMM~RY OF T~E INVENTION
The present invention provides an apparatus for labeling
moving packages in which a carriage mounted, integrated
printer-applicator head prints and applies the package label.
In the preferred application, labeling information is
input for a package which is then placed on conveyor system
~ for transpoxt. Sensors check the package geometry or
~onfiguration and its location on the conveyor. An edge
sensor signals when
the package has reached a predetermined position on the
conveyor.
~ The package locatlon and configuration data along with the
`~; labeling information are transmitted to a controller which
receives and correlates the data. The controller produces a
label control signal which is tran~itted to the labeling
ZO station. Vertical and latera~ drive motors position the
;~ carriage mounted, integrated printer-applicator assembly in
response to the label co~trol signal. The printer-applicator
(P-A~ assembly both prints and applies the required label to
the package. ~
The controller stores the P-A assembly position so that
the P-A assembly moves directly to the next desired position
asjthe sequence described abov~ lS repeated. T~ avoid impacts
with packages that have shifted or turned as they traveled
along the conveyor, sensors are provided to slgnal the P-A
ass mbly to ~ranslate vertically.
It is an object of this invention to provide a system tha~
will quickly and accurately label moving packages.
an o~ject of this invention to provide a label
applicator which does not require that it return to a fixed
~ home po~ition between labels.
3~23292 ~ PCT/US93/04556
It is an object of this inven~ion to provide a label
applicator that moves vertically and laterally in a fixed
plane normal to the diretion of package movement.

Tne assembly 51 is comprised of an open framework 63 which
straddles the conveyor belt 3. The framework 63 is comprised
of four vertical frame members 133, 134, 135 and 136 which
. define the four corners of the framework support assembly 63.
The vertical frame members 133-136 are flxed in posi.tion on
the sides of the conveyor 3 at 137. The longitudinal frame
members 139 and 140 are respectively affixed to the vertical
frame members 133 and 34 at upper and lower positions. A
~;~ second pair of longitudinal frame members 141 and 142 are
affixed to the second pair of vertical frame me?~bers 136 and
¦~` 137 in like fashion. Straddling the conveyor belt 3 are the
cross membe~rs 144 and 145. The cross member 144 connects the
- top vertical frame members 133 and 135. The cross member 145
~ connects the tops of ~he vertical frame members 134 and 136.
'!1` ;~ 15 An intermediate cross member 143 also connects the vertlcal
frame members :133 and 135 at an intermediate position which
above the maximum expected package height.
As can be seen~from the: above~, the framework 63 is
essentially a box frame which straddles the conveyor 3. While
2~0 ~ the spe;ci~ic construction is not important, it must be
remembered that the frame 63 has to withstand rapid movement
of the P-~A as~embly: and:must be sturdy enough to permit
: positive location~of the P-A assembly over the con~eyor 3.
The linear actuators~ 146 and 147 are affixed to the
~} ~, :
respective lo~gitudinal frame members 139 and l~O, and 141 and
142, on~either side of the conveyor a~d in front of the
respective vertlcal~frame member 133 and 13~. The linear
actuator 172 is horizontally attached, via a pair of mounts
~: 173, to the vertical linear actuators 146 and 147. In the
pré~erred embo?~imen~', the linear actuators 14~, 147`and'1t2
are Part NO. 1251001 from Macron Dynamics, Inc. t 405 Caredean
Drive, Horsham, PA.
The carriage assembly 170, rides on the horizon~al linear
actuator 172 and i9 moved acro~s the conveyor 3 by the lateral
direction drive motor 178. Mount~d on the lateral drive motor
178 is a rotary encodex or position sensor 179 which
: csn~inually transmits the position of the carriage assembly
170 ~o it can ~e tracked by the secsndary controller 160. In

Kishwaukee Street, P.O. Box 106, Rockford, IL 61105-0106.
~l~ 5 The horizontal l~near actuator 172 and the carriage
assembly ~70 are raised and lowered on the vertical linear
actuators 146 and 147 by the vertical drive motor 150 which
is attached to the support assembly 63 by a motor $upport
bracket 148. The dri~e pulley 151 on the vertical drive motor
is coupled to the shaft pulley 156 by bel~ 158. This
combi.nation drives a transverse shaft 154 which engayes the
upper ends of vertical linear actuators 146 and 147. -Rotary
- :encoder or position sensor 157 tracks the turning of the
~:~ transverse shaft 154 for: the secondary con~roller 160 which
~: 15 controls`the vertical dri~e motor 150. An electric brake 153
is attached:to the opposing end of the transver e shaft as a
safety feature~. In the~ preferred embod1ment, the ~ertical
;drive motor lSO and rotary encoder 157 are Pacific Scientific,
:Motor and~Control Dlvision, Part No. R65HENA-R2-NS-~S~00. The

25~ assembly 200. The~printer~controller~202, Figure:4,~ is aIso
attached ::to the carriage :assembly 170. ~ Mounted on the
printer-applicator support bracket 174:above~the P-A assembly
2:00 are a label supply reel 18~4,~which~supplies labels on a

200. If a package has shiftedl the strike sensors signal'the
secondary controller to raise the P-A assembly 200 to avoid
possible damage to the assembly andjor the package.
If for any reason a label l91 cannot be applied to a
package, such as strike sensors 180 indicating that ~he
package has exceeded the height limitation, the controller 13
activates the air cylinder 211 to swing the catch plate ~16
into position under the label dispenser 207. The label 191
is then blown onto the catch plate 216. I~ the catch pIate
0 '216 is full, photo eye~ 224 signals the controller that
operator assistance is required.
Because the P-~ assèmbly 200 can both print and apply a
shipping label, it is not necessary to have the P-A assembly
, 200 return to a retracted or home position befor'e printing and
15~ ~ ~ applying~a label~to the next package,on the conveyor 3. The
P-A~àssembly~;2~00;proceeds~directly from~its last'position to
