PhATEN MODULE FOR A MODULAR MAILING MACHINE

BACKGROUND OF THE INVENTION
This invention relates to imprinting systems, such as, postage meter mailing machine, which systems are used to imprint information on a sheet-like median and, more particularly, to a postage meter mailing machine utilizing flat bed printing technics and employing a platen assembly.
In the mail processing field, it is most desirable for a system operator to be able to deliver to mail processing equipment a batch of "Mixed mail", that is, the batch is comprised of a large number of envelopes of varying dimensions, particularly thickness, and weight. The ability -of a mail processing system to process a large variety of -;
mixed mail eliminated the need of the system operator from performing the preliminary steps of presorting the mail. It -~
is further desirable for mail processing e~uipment to be able to weigh the individual envelopes and affix the appropriate postage value indicia in accordance with the envelope weight. It is generally considered advantageous if the mail processing equipment can imprint a quality indicia upon envelopes varying in thickness from that of a postcard to approximately a quarter (1/4) of an inch. It is also -~
considered advantageous for the mail processing equipment to possess the capability to imprint a postage indicia on tape strips which can be affixed to packages to large to be accepted by the mail processing equipment.
It is known to provide mail processing equipment comprised of a feeder for singularly delivering envelope in series to a transport assembly. The transport assembly deposits the envelope on the scale for weighing. After a sufficient time to assure a true scale reading of the envelope weight, commonly referred to as "weight on the pause", the transport assembly again assumes control over the envelope and delivers the envelope to the a mailing machine.
The mailing machine is most commonly comprised of a intègral transport assembly and attached rotatory print drum - 2 - ~
,' ' type postage meter. The mailing machine transport assembly assumes speed control over the envelope performing any necessary speed adjustments to the envelope required to match the envelopes traversing speed with the imprinting speed to ~ ~
the postage meter print drum to promote a quality indicia ~ `
print. It is known for the postage meter to include a value setting mechanism under the influence of the scale which causes the postage meter value setting mechanism to adjust ;
the postage meter printing mechanism for printing of the~;
appropriate postage rate on the approaching envelope according to the envelope weight as determined by the scale.
The mail processing system depicted above has as its primary objectives ~i) the capability to process a dimensionally wide variety of envelopes particularly with respect to thickness and weight (ii) as fast as possible in terms of envelope per second (iii) while applying a quality postal indicia. The described mail processing system has several limiting factors with respect to increasing throughput relative to system cost. One such limiting factor is represented by the time required in transporting the -~
envelopes from one process station to another. Another limiting factor is reflected in the time necessary to obtain an accurate weight from the scale. While such factors as;~
transport time and weighing time can conceivable be decreased by incorporating advance system techniques, the rule of;~
diminishing returns predicts that small improvements in system throughput by such an incorporation would be ~` `
achievable at disproportional increases in system cost.
In the aforedescribed system, postage meters utilization of flat bed printing technics are seldom -employed. That is, such postage meters require the envelope to stationary located in the postage meter in order to imprint the postage indicia. As a result, postage meters ~ ,., '~

~` 1 33o~07 utilizing flat bed printing technics in such mail processing equipment would conventionally introduce another interruption to the envelope process procedure ~ -and, hence, the preference for postage meter~ which employ rotary printing techniques.
One possible alternative means of increasing the throughput of such mail processing systems is to provide multiple scales and a suitable transport system such that the scales are placed in alternative use. Such an arrangement would conceivably allow overlapping of system process or function to achieve a significant increase system through. However, such an alternative represents added cost from both an equipment and system complexity standpoint.

A drive motor is mounted to and between parallel support brackets such that the rack posts are outboard of the respective brackets. The drive motor includes a drive shaft. The drive shaft has a gear mounted to its ends in constant mesh with a respective rack post. Actuation of the drive motor 97 can cause the rack post to elevate the platen plate to bring the elastomeric member into engagement with a ~-properly positioned envelope in the meter register projection ~ ~-area and, in so doing, cause an indicia to be imprinted on the envelope.
The mailing machine process station is comprised of an integral scale suitable adapted to accommodate the transport assembly, an envelope sealing assembly complimentary to the transport assembly is optionally provided, the vertically displaceable flat printing platen and a postage meter support assembly for supporting a suitably attached postage meter.
By employing a multiple function processing station the ,~
mailing machine throughput is substantially increased by facilitating minimum time lag between functional operations on each envelope and eliminating the transportation time required by multiple process station systems. Particularly, since the envelope is placed in a stationary position for weighing by suitable accommodation in the process station, it ;
is now preferable to utilize flat bed printing techniques facilitated by the platen module and a suitable meter module Generally the scale is isolation mounted to the mailing machine base and includes a plurality of slots in the ~ ;~

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The novel postage meter mailing machine particularly ... . .. ..
` suited for employment of the present invention employs a -~
novel modular architecture. That is, the mailing machine is comprised of subsystems which are not interdependent.
Therefor, the mailing machine can be configured to include only those subsystems modules necessary to meet particular operational needs for a given application environment or, alternatively, the mailing machine can be configured to ~': . .' '.;.:

7 ~-include the full array of subsystems modules providing maximum application flexibility. For example, where the -~
used environment is restricted to processing uniform mail, the scale module, subsequently described, may be omitted in substantial portion from the mailing machine without affect the system performance of remain modules or the system controller. ~ ~ ;
Referring to Figs. 1 ancl 2, a mailing machine, generally indicated as 11, employs a novel subsystems modular architecture comprising a scale module 13, a transport module 12, a postage meter module 15, a tape feed module 17, a inking module 19, and a platen module 21. The modules are located within the mailing machine -~ ~ , 11 such that the scale module 13 is located frontwardly of parallel support walls 33 and 35 of the mailing machine 11. The support walls 33 and 35 are fixably mounted to the mailing machine base 30 in lateral spaced apart relationship. Mounted to the base plate 30 between the support walls 33 and 35 is the ink module 19. Mounted above the ink module 19 to the support walls 33 and 35 is the postage meter module 15. The platen module 21 is mounted to the base 30 just below a registration portion of the postage meter 15, to be described mora fully later. In addition, the mailing machine has mounted to the wall 35 the tape feed module 17 of the present invention coactive in the preferred embodiment with a tape cutting mechanism 230. ~;~
Referring to Figs. 1 and 3, the scale module 13 most suited for the present invention is of the resilient type more fully described in U.S. Patent No.
4,778,018, entitled APPARATUS AND METHOD OF DETERMINING

dependent upon the total mass of the platforml and anything -connected thereto, such as, envelope residing on the platform, and the platform spring constant. As a result the ~-mass of an envelope residing on the platform can be determined and a weight assigned by comparing the oscillation ;
obtained subsequent to residence of the envelope with the known nominal oscillation. For the purpose of brevity, the heredescribed portion of the scale module 13 represents that portion of the res~lient type scale necessary to illustrate the scales' interrelationship with the mailing machine 11.
Referring particularly to Figs. 1, 2, and 3, the scale module 13 is of the resilient type and includes a weighing plate 37 supported by vertical beam members 40 at one of their respective ends. The other end of each beam member 40 is fixably mounted to a counter plate 42. The mailing machine base 30 includes a plurality of scale support post 36 each support post 36 including a flex member 34. Each flex ; member 34 is fixably mounted to the counter plate 42 in such -~
a way as to provide isolation mounting for the scale module 13 from the base 30.
The weighing plate 37 is generally rectangular in shape and includes a longitudinally extending recess 38 formed along the rearward side of the weighing plate 37 also formed in the weighing plate are a plurality of co-linearly aligned slots 41 ~not shown in Fig. 3 for the purpose of clarity). A
first generally C-configuration clamp 43 is fixably mounted along the rearward side of the weighing plate laterally to one side of the recess 38. A second generally C-configured ~
clamp 45 is fixably mounted to the rearward side of the `-weighing plate 37 laterally to the other side of the recess 38. A support beam 47 (shown in phantom in Fig. 3 for the -~
purpose of clarity) is fixably mounted at its ends to the -respective clamps 43 and 45. Rotatably mounted by conventional means to the support beam 47 is a plurality of clamping members 49 each of which is mounted such that it is positioned over a respective one of said slots 41. Each of the clamping members 49 includes a mounting arm 51 rotatably mounted to the support beam 47 at one end and biased downwardly by any conventional means such as a spring. The other end of the mounting arm 51 has fixably mounted thereto a generally arched flange member 53 laterally sized to prevent the flange member 53 from venturing into a respective slot 41.
It should be appreciated that to the extent that the weighing function is not desirecl to be included, the scale module as aforedescribed, inclusive of the functional capabilities cited in the applications herein incorporated, may be illuminated. The only modification or substitution necessary is the employment of a transport plate, of like construction to the weighing plate 37, which transport plate can be fixably mounted directly to mailing machine base 30 and including the clamps 43 and 45, support beam 47 and clamp members 49. The members 43, 45, 47 and 49, in the preferred embodiment of this invention, are maintained for interaction with the transport module in a manner hereafter described.
It is noted that as viewed in Figs. 1, 2, 3, and 4, the preferred embodiment of the present invention includes a sealing module, generally indicated as 42. The sealing module 30 is comprised of a generally L-shaped support member ` ;`~
44. The support member 44 is fixably mounted at one end to `
the mailing machine base 30. The other end of the support ~-member 44 rotatably supports a plurality of sealing members 46 biased downwardly by a respective spring 48. The sealing ~-;
members 46 are aligned longitudinally in a generally staggered relationship and include tab 56. A solenoid 50 is `
fixably mounted to the support member 44 such that the ~ -solenoid piston arm 52 abuts a portion of a transfer link 54 `~
slidably mounted to the support member 44. The transfer link 54 in part abuts the respective sealing member tab 56.
Actuation of the solenoid 50 causes the solenoid piston arm 52 to displace the transfer link 54 which thereby causes the sealing members 46 to rotate to a spaced apart relationship to the weighing plate 37 during the weighing process.
Referring to Figs. 3, 4, and 5, the transport module 12 i -is comprised of a plurality of first guide rollers 57 are rotatably mounted to a frame 58 (best shown in Figs. 3 and - :~.~.
"'.:,..,.,'', ...

- lo - ~ 330907 : ~

4). The frame 58 includes support seats 70, each seat 70 . ~ ~
having a resident seat 72. A plurality of generally L-shaped ~ .
support members 74 are fixably mounted at one end to the base ~:
30 such that they do not interfere with the counter plate 42 of the scale module. The other end of the support member 74 is receive in a respective seat 70 of the frame 58. Each support member 74 includes a seat 76 having a guide pin 78 : :
biased in the vertically upward direction by a spring 80 residing therein. A portion of the guide pin 78 also, in .
part, resides in the seat 72 of the respective frame seat 72.
Also rotatably mounted to the frame 5B is a plurality of rollers 61 positioned vertically downwardly from and between a adjacent guide rollers 57. Fixably mounted by any conventional means so as not to interfere with the operation of the scale module 13 to the base 30 of the mailing machine is a bi-directional drive motor 63 and associated drive train, generally indicated at 65. An endless belt 69 is placed in driving communication with the drive train 65 which includes a one way clutch arrangement, generally indicated as 67. The endless belt 69 is positioned in a serpentine manner , . , .: . . .
around rollers 57 and 61 thereby providing driving communication between the drive motor 63 and the roIlers 57.
When belt 69 is driven in the envelope feed direction of the mailing machine by the drive motor 63 as permitted by the one-way clutch 67, the frame 58 will assume the nominal : or first position pursuant to the urging of the spring biased .
guide pin 78. In the first position, the rollers 57 are - -: positioned by the frame 58 to extend through and slightly ;~
above a respective slot 41 in the weighing platform 37. When - : `
the belt 69 is driven in a reverse direction to the envelope .
feed direction, the one-way clutch prevents continues displacement of the belt 69 causing the belt 69 to impart a downward force on the frame 58 overcoming the biasing force of the springs 80. As a result, the frame 58 is displaced downward to a second position causing the rollers 57 to be withdrawn from the slots 41. It is noted that the drive train 65 includes a take-up roller 66 biased in a conventional manner such that when the frame 58 is in the . ~

~. .
second position the take-up maintains the belt 69 in a taut ~-condition.
It is now apparent that when the rollers 57 are withdrawn from the slots 41, the clamps 47 bias a envelope on the weighing plate thereagainst which facilitates the weighing process. When the rollers 57 are journeyed partially into the slots 41, the clamps 47 assist the transport function.
Referring to Figs. 1, 2, 4, and 12 and more particularly Fig. 6, as afore noted, the postage meter 15 is -mounted between the support walls 33 and 35. The postage meter includes a forwardly located registration area, generally indicated as 82. Mounted to the base 30 of the ;~
mailing machine just below the register area 82 of the postage meter 15 is the platen module 21. The platen module 21 includes a support wall 81 fixably mounted the base 30. A
plurality of C-brackets 83 and guide pins 85 are fixably --mounted to one face of the support wall 81 in vertical alignment to allow a platen guide rod 87 to vertically slide along a defined vertical path. A platen guide rod 87 is j -~- -laterally captured by the C-brackets 83 and guide pins 85 and ` ~-has fixably mounted to its top a platen plate 89. Also fixably mounted to the platen plate in laterally spaced relationship is a first and second rack post 91 and 93, respectively. Fixably mounted atop the platen plate 89 is a ~ -elastomeric material having a generally rectangular shape of `~
uniform thickness.
A drive motor 97 is mounted to and between parallel support brackets 99 such that the rack posts 91 and 93 are outboard of the respective brackets 99. The drive motor 97 includes a drive shaft 101 which extends axially through the drive motor 97. At each end of the drive shaft 101 is `-fixably mounted a gear 103 aligned to be in constant mesh with a respective rack post 91 and 93. It is now appreciated that actuation of the drive motor 97 can cause the rack post to elevate the platen plate 89 to bring the elastomeric member 95 into engagement with a properly positioned envelope ~"':, ' . .:, ., in the meter register projection area and, in so doing, cause an indicia to be imprinted on the envelope.
Referring now to Figs. 1, 7, and 12, the inking module 19 is located between the support walls 33 and 35 of the mailing machine 25. A mounting plate 111 is fixably mounted vertically to the base plate 30. A drive motor 113 is fixably mounted to the mounting plate 111 such that the output shaft 115 extends through the plate 111. Fixably -~
mounted around one end of the output shaft 115 outboard of the plate 111 is a gear 117. A second gear 119 is pivotally mounted to the base 30 in constant mesh with gear 117. A ~-linkage assembly comprised of a first link 121 is fixably mounted to the second gear 119 at one end. Fixably mounted along the first link 121 is a second link 123 and a third link 125 in spaced apart parallel orientation a fourth link 127 is pivotally mounted at its respective ends to a respective link 125 and 123. A first and second transfer link 129 and 130, respectively, are pivotally mounted in spaced apart relationship at one end to the fourth link 127.
Fixably mounted inboard to each of the support walls 33 and 35 is a first guide pin 135 and a second guide pin 137. -Each of the transfer links 129 and 130 extend respectively below a guide pin 135 and above a guide pin 137 such that the guide pins 135 and 137 act to guide the longitudinal displaceable path, respectively, of the transfer links 129 and 130. The guide pins 135 and 137 also provide vertical support. Fixably mounted to the forward end of each of the transfer links is a ink pad well 139 in which a ink ;~
pad resides (now shown). At the other end of each of the transfer links 129 and 130 is formed a tilting surface 141.
It can therefore be appreciated that upon actuation of the motor 113 the linkage assembly is driven forwardly. The pins ~ ~-135 are positioned such that when the ink pad tray 139 is positioned just below the register area 85 of the meter 15 the tilt surface 141 are brought into forced engagement with the pin 135 causing the transfer links 130 and 129 to be tilted upwardly elevating the ink pad well 139 into engaging contact with the register area 85 of meter 15.

~ I 3~0907 , Referring now to Figs. 1, 4, 8, 9, 10, and 12, the tape module 17 is slidably mounted to the wall 35 along a track 150 formed along the outboard side of the wall 35. The tape module consist of a rail 151 which is slidably mounted longitudinally to track 150 to define the longitundinal displacement path of the tape module 17. A bracket 155 is fixably mounted to the rail 153. A second bracket 157 having a generally vertically extended slot 159 is mounted to the -~
bracket 155. The bracket 155 includes a back wall 161 which ;~
has mounted thereto a first tape drive motor 163 and a second ~ ;
tape drive motor 165. The bracket 155 includes a first set of longitudinally aligned bracket flanges 167. Pivotally mounted to each of the flanges 167 is one end of a first pivot arm 169. The bracket 155 further includes a second set ~-of bracket flanges 171 which, in like manner, has pivotally `-mounted thereto, respectively, one end of a second pivot arm -173. The other end of each pivot arm 169 and 173 is - - `
pivotally mounted to a tape guide housing 175.
The tape guide housing 175 has an entrance 177 aligned opposite an exit 179. Fixably mounted in a cantilever fashion to the tape guide housing 175 to extend outwardly from the exit 179 of the tape guide housing 175 is a tape ~-~
track 181 having a wedged shape feed member 183 extending partially into the tape guide housing 175. The tape track -~ ;
181 and the feed member 183 are mounted to the side walls of ~ `
the housing 175 to laterally extend across the exit 179. It is noted that the tape track 181 is comprised of a first and second channeled side walls 174 and 176, respectively, having .,~ :
a strip member 178 supported by and longitudinally between the side walls' channel (ref. to Fig. 7a). Rotatably mounted in the tape guide housing 175 is a first and second tape drive roller 185 and 187, respectively. Rotatably mounted in the housing 175 opposite the first drive roller 185 is a first idler roller 187 and, in like manner, a second idler roller 191 is rotatably mounted opposite the second tape drive roller 187. A flexible shaft 193 communicates the first motor 163 to the first tape drive roller 185 and, in ~
like manner, a second flexible shaft 195 communicates the `

- 1 330~07 second tape drive motor 165 with the second tape drive roller 187.
The housing 175 further includes a flanged portion 197 having fixably mounted thereto a plurality of first guide pins 198 and a plurality of second guide pins 199. A dual tape support assembly 200 is fixably mounted to the base 30 and rotatably supports a first and a second roll of tape Z03 and 205, respectively. The first roll of tape 203 is threaded such the the guide pins align the tape 203 for ~-iourney into the housing 175 ancl tape track 181. The tape --203 is located in the tape track 181 so as to be captured ~ -between the channeled side walls 174 and 176 resting on the strip 178. As shown in Fig. 8 and in accordance with the ` ~-preferred embodiment of the invention, the tape 203 is a - -~
backing tape supplied with sufficient backing lead such that -`-the backing 180 will extend in a reverse direction below the strip 178 to and between the idle roller 191 and the drive roller 187 such that actuation of the drive roller 187 on the tape backing 180 causes the tape 203 to be advanced and the ; 20 backing pealed away. The tape 205 is journeyed around the pin 198 to pass between idle roller 198 and drive roller 185 and into the tape track 181 to rest on the tape 203 and ;~
captured between the channeled side walls 174 and 176.
Optionally, it may be desired for the tape 203 to be of the non-backing type. As indicated in phantom in Fig. 9, the -tape can be optionally threaded directly between rollers 187 and 191 of the track 181. -Referring more particularly to Figs. 10 and 12, the tape module 17 is slidable along a track 150 formed formed in wall 35 pursuant motivation of second bracket 157. It is noted that the tape module 17 is so positioned relative to the registration area 80 of the postage meter 15 and the platen module 21 such that the track 181 is located in a first position between the postage meter registration area 80 and the platen module 21. In a second position the track 181 is repositioned below the postage meter 15 clear of platen ~ ~;

~ 1 33~9()7 In order to motivate the second bracket 157 and, in -;
turn position the track 181 in the first (as indicated in phantom in Fig. 12) or second position, a motor 210 is fixably mounted to the mailing machine base 30. Fixably mounted around the output shaft of the motor 210 is a pulley ~ ~-212. Rotatably mounted to the wall 35 is a double pulley assembly 214 which includes a first pulley 216 and second -- --~
pulley 220. The first pulley 216 is in driven communication -with the motor 210 through an endless belt 218 journeyed between the pulleys 212 and 216. A crank assembly 222 is ; ~-;
rotatably mounted to the wall 35 and includes a pulley 224 in driven communication with the pulley 220 of the pulley assembly 214 through an endless belt 226. The crank assembly 214 also includes a crank arm 228 having a slide pin 230 residing in the slot 159 of the bracket 157 of the tape module 17.
Motivation of the tape module 17 along the track 150 is accomplished by causing the motor 212 to rotate the pulley 212 in the direction shown in Fig. 10. The rotation of pulley 212 is transferred to pulley 224 of the crank assembly 222 through the double pulley assembly 214 by belts 218 and 216. The rotation of pulley 224 through one-half revolutions causes the tape module 17 to displace from the first position `~
to the second position. Further actuation of the motor 210 causes the pulley 224 to further rotate to complete the revolution resulting in the tape module returning to the first position.
Referring to Fig. 11, the mailing machine may further include a tape cutter module 230. The tape cutter module 230 ~-~
is comprised of dual track 232 mounted outboard of the wall ~;
33. A member 234 is slidably mounted to track 232. A lever arm 236 having a vertically directed slot 238 is fixably mounted to the member 34. The lever arm 236 includes a portion 240 which extends in a horizontal cantilevered manner and has a rotary blade 242 rotatably mounted to the end of the lever portion 240. A cutter beam 244 is mounted to the wall 33 to cooperative act with the rotary blade 242.

Actuation of the cutter module 230 is provided by the motor 210. The double pulley 214 is fixable mounted centrally around a shaft 246 rotatably mounted to the wall 35 by any conventional means. The shaft 246 extends longitudinally to and is rotatably mounted in a support member 248 fixably mounted to the base 30 of the mailing machine. Fixably mounted around a portion of the shaft 246 generally adjacent to the member 248 is a crank arm 250. The crank arm 250 includes a pin 252 slidably captured in the slot 238 of the lever arm 236 sucb that upon initial one-half rotation the motor 210, acting through the double pulley sha~t 246 caused the lever arm 236 to be displaced by the crank arm pin 252 to a second position (indicated in phantom in Fig. 11).
Further actuation of the motor 210 causes the pulley 224 to further rotate to complete the revolution resulting in the rotary cutter blade in coaction with the beam 244 -~

It is intended that the mailing machine 11 operate such that the transport module 12 receives a envelope from a suitable feed mechanism (not shown). The ;
transport system properly positions the envelope on the weighing plate relative to the meter module 15. The transport rollers 57 are then caused to withdraw, in the manner aforedescribed, under the influence of the motor 63. Simultaneously, the inking module 19 has been ~ -actuated, in the manner aforedescribed, to apply imprinting ink to the registration area of the postage meter module 15 and withdrawn to the first position prior to the arrival of the envelope. Upon the arrival of the envelope in proper position at the process station and withdrawal of the transport rollers 57, scale module 13 will weight the envelope, in a manner ; described in U.S. Patent No. 4,778,018, and inform the meter for meter setting, in a manner described in U.S.
