11710/76-L C JTnomusONm Comm woAlth Govcrnmcnt Prnier. Canberra IA CODE BREAK MECHANISM FOR STACKING APPARATUS BACKGROUND OF THE INVENTION This invention relates to a code break mechanism for a stacking apparatus receiving a stream of articles, more particularly to a code break mechanism for producing discontinuities in the stacker article stream in accordance with a selected parameter change in the article stream.
In article processing systems, generally the last process step is the collection of processed articles. For i0 example, in a conventional mail processing system, a power stacker may be employed to collect envelopes ejected from a mailing machine. Generally, the power stacker receives the envelopes in a seriatim and uniform manner and stacks the envelopes. An operator periodically removes the accumulated envelope stack from the stacker for packaging in preparation for subsequent deposit with a mail forwarding agent, such as, the United States Postal Service (USPS).
Mail forwarding agents, such as, the USPS, offer to °o0 the mailers special postage discount rated for mail which is
O
2 0 presorted, for example, by zip code. Therefore, where the mail is processed in a presorted manner, for example, according to zip code, it would be advantageous to the S operator for the power stacker to include a means for visually marking zip code changes or breaks within the stacker received mail stream.
SUMMARY OF THE PRESENT INVENTION It is an object of the present invention to present a code break mechanism particularly suited for employment in a power stacker.
A particularly suited power stacker includes a deck fixably mounted to and supported by a housing such that the deck is position at a 150 rearward reclined angle. A registration wall is fixably mounted to the housing and extending generally perpendicular relative to the deck. A stack wall is slidably mounted to the housing at one end.
-2- The zip code break mechanism is comprised of a deflector plate pivotally mounted within a mating opening in the registration wall. The deflector plate in a first or normal position is located coplanar with the registration surface of the registration wall. A solenoid, responding to a control signal from a controller, is fixably mounted in the housing and communicates with the deflector plate through a linkage such that actuation of the solenoid causes pivotal displacement of the deflector plate from the first position to the second position. When the deflector plate is positioned in the second position, it can thereby laterally deflect the zip break envelope pursuant. The zip break envelope is thereby laterally misaligned with respect to the envelope stack allowing an operator to visually observe stack zip code breaks.

Referring to Fig. 2, a registration wall 145 is fixably mounted longitudinally along the rear wall 23 and o orientated generally perpendicular to the deck. The registration wall 145 includes a recess 147 angled generally S° perpendicular to the reclined surface 115 of stack wall 111.
^coo A brace 149 is fixably mounted to the back surface of the registration wall 145. The brace 149 includes a shaft 151 rotatively mounted therein such that the shaft 151 extends generally perpendicular to the recline surface 115 of the stack wall 111. A pulley 153 is fixably mounted to the of shaft 151. The pulley 153 is an endless belt 155 in driving communication with the pulley 91 mounted shaft 63. A threaded hub 157 is fixably mounted around the shaft 151.
The registration wall 145 further includes a slot 160. A yoke 165 is pivotally mounted in slot 160 to the registration wall 145. The yoke 165 carries a yoke wheel I 167 rotatively mounted between the forks of the yoke 165.
The yoke 165 is adjustable mounted in slot 160 such that the yoke wheel rests on the deck 31. Also fixably mounted to the back of the registration wall 145 is a guide rod 166 which extends slidably through a slide member 165 fixably mounted to the registration wall 145 and pivotally mounted at one end to the stack wall 111. A return spring assembly 166 having one end of its flex strip 168 fixably mounted to the stack wall ill. In like manner a second return spring assembly 170 is fixably mounted to base 13 having one end of it flex strip 172 fixably mounted to the stack wall 111.
Referring to Fig. 4, the code break mechanism, generally indicated as 200, includes a deflector plate 202 pivotally mounted in a matting opening 204 in the registration wall 145. A bracket 201 is fixably mounted to the back face of the registration wall 145. Pivotally mounted to the bracket 201 is a generally L-shaped link 206 oo having a first slot 208 and a second slot 210. A pin 212 is formed to the back face of the deflector plate 202 such that 000oo0 the pin 212 is captured in the slot 208 of the link 206.
A bracket 214 is fixably mounted to the underside of the deck 31 and fixably supports a rotary solenoid 216. The 0 output shaft 218 of the rotary solenoid 216 has fixably r mounted thereto to one end of a link 220. The link 220 extends through a aperture 222 in the rear wall 23 and has a o slot 224 formed in its other end. A second bracket 226 is fixably mounted to the rear wall 23. Slidably mounted through the brackets 201 and 226 is a link 228 having a hub H" oo 239 formed at one end slidably captured in slot 210 of link 206 and at the other end of link 228 a formed pin 232 is slidably captured in slot 224 of link 220. The link 228 includes a coupling 234. A spring 236 is coiled around the link 228 between the stop rim 234 and the bracket 201.
Referring further to Fig. 5, in operation, a suitable motor controller 171 is in electrical communication through line 173 with a envelope feed device 175, for example, a mailing machine, and through line 177 with the motor 49 and rotary solenoid 216 of the power stacker 12. The motor controller 171 synchronously controls the operating speed of S the power stacker 12, rotary solenoid 216 and the feed device 175 such that envelopes, for example, 5 inch envelope -6delivered by the feed device are received by the power stacker in a shingled fashion with approximately a .75 inch spacing between the leading edge of successive envelopes.
The envelopes are transported by the belts 55, 57 and 59, which are under the drive influence of motor 49 through belt 83 and shaft 63, under the yoke roller 167 such that the leading edge of the lead envelopes engages the stack wall facing 115 and is caused to assume a generally vertical position against the stack wall. The subsequent envelopes are caused to assume a generally parallel orientation relative to the lead envelope. The positioning of envelopes is assisted by the edge engagement of the envelopes with the threaded hubs 101, 2.03 and 157.
Upon activation by the motor controller 171 00e 00 occasioned by the presence of a code break letter being 0 0~ discharged from the feed device 175, the rotary solenoid 216 rotatively displaces link 220 in the direction of arrow A.
The displacement of link 220 is transmitted by link 228 to cause link 206 to pivotally displace. The displacement of link 206 causes the deflector plate 202 to pivotally o displace from a first position coplanar with the registration wall 145 to a second position whereupon the deflector plate 202 encounters the code break envelope in route. The code break envelope is consequentially displaced 250 laterally relative to the other stacker received envelopes.
00 As the envelopes are caused to vertically stack, edge engagement of the envelopes with the threaded hubs 101, 103 and 157 cause the stack wall to displace outwardly. The rods 117, 119, 121 and 160 support the stacked envelopes as the stack wall is displaced. During vertical stacking of the envelopes, the code braak envelope remains perceptively displaced laterally.
The afore description is of the preferred embodiment of the present invention and should not be viewed as limiting to the invention. The scope of the invention is defined by the appendix claims.
