CHECK FEEDING AND ALINING MECHANISM 3 Sheets-Sheet 3 Filed Nov. 1, 1960 FIG.5
m T TR EE E MnNP N N m A o NBN "H wwm A NN mm mm H JF United states This invention relates to material-handling devices and more particularly relates to an improved means for the feeding and reversing of bank checks and means for stacking the checks in a predetermined position.
The invention is applied to a data-processing system of the type employed in a bank or other financial institution. Under this system, checks that are received are encoded with the amount of the check and a transaction code to allow for the processing of the checks by data-processing equipment. The checks are then stacked in bundles in a prearranged position for insertion into a check sorter for further processing operation. The use of prior means for feeding and stacking the checks after an encoding operation resulted in the checks being stacked on an edge which was opposite to the way they were to be inserted into the sorter. Also, the checks were sometimes mixed and turned over, requiring the operator to jog the checks so as to aline the edges of each of the checks and to arrange the checks in the position that is required for insertion into the check sorter. In most cases, this required the checks to be reversed. Thus it is an object of this invention to provide an improved material-handling device which will reverse the position of the material handled during a feeding operation.
It is another object of this invention to provide an improved material-feeding device which will feed and aline the material in a prearranged position.
It is another object of this invention to provide an improved record-feeding device which will have positive control of the record material throughout the feeding operation.
It is a further object of this invention to provide jamatent detecting means which will lock up the parent machine upon the jamming of a check in the stacker, thereby warning the operator of such an occurrence.
It is another object of this invention to provide means for controlling the feeding of the checks so that they may be directed into either of two different receptacle means.
It is still another object of this invention to provide a material-feeding device which is simple to operate, compact, and capable of feeding material at a high rate of speed.
With these and other, incidental, objects in View, the. invention includes certain novel features of construction feeding device, showing the driving means for the feed rollers.

3 1 00,1 13 Patented Aug. 6, 1963 FIG. 6 is a sectional View taken along the lines 66 of FIG. 1, illustrating the details of the means for feeding and stacking the checks in an alined position.
Referring now to FIG. 1, there is shown the check stacker enclosed within a cabinet having a back panel 99 and side panels 100 and 101. As shown more clearly in FIG. 6, it may be seen that the stacker has a rear panel 98, which forms with the back panel 99 a compartment within which is located the driving apparatus for the stacking means, shown more clearly in FIG. 2. The stacker normally has two front panels. One front panel covers the top portion of the stacker, while the other front panel covers the lower part of the stacker. The center section of the stacker is open to facilitate the removal of the checks from the stacking bins, described more fully hereinafter. Located in the right side panel 101 is an aperture 102, through which extends one end of a check feed guide 103. The check feed guide 103 is formed by a top guide 104 and a lower guide 105. Checks are fed into the check guide 103 to be reversed and stacked after a printing operation has occurred in the parent machine.
The stacker is normally associated with a self-contained printing mechanism of the type disclosed in United States Patent No. 2,935,934, issued to Paul H. Williams et al. on May 10, 1960. As disclosed in that patent, the printing mechanism is under the control of a keyboard device which when operated will imprint on the check in magnetic characters the amount of the check. After the printing operation has occurred, the check is fed into the check guide 103, where it is successively engaged between two sets of rollers, each set being composed of a feed roller 107 and a pressure roller 108. As shown more clearly in FIG. 4, the pressure roller 108 consists of a central portion and a pair of side plates 179, which are slightly larger in diameter than the central portion. The pressure roller 108 is rotatably supported on a yoke member 109 (FIG. 1), the other end of which is biased in an upward direction by a spring 110, supported on the top guide 104. The yoke member 109 is rotatably attached to a support 111, so that, upon the engagement of a check by the rollers, the pressure roller 108 will be rotated in an upward direction against the urging of the spring 110. By this construction, the roller 108 will urge the check into engagement with its associated feed roller 107. Associated with the yoke is an adjustment arm 112, rotatably mounted on the support 111 and having a slot 113. A stud 114, mounted on the yoke 109, is positioned within By this arrangement, the pressure roller 108 is positioned adjacent to but not in contact with its associated feed roller 107. This is required because the central portion of the pressure roller 108 is constructed of nylon, while the feed roller 107 is made of rubber. Contact between these two rollers would result in the destruction of the rubber roller. It will be seen from FIG. 4 that the side plates 179 of the roller 108 overlap the peripheral surface of the feed roller 107 when the pressure roller 108 is positioned in the above-described manner. Thus, when a check or other record document is engaged between the roller 107 and the side plates 179, the record document will be bowed towards the roller 108 and forced into engagement with the feed roller 107 due to the pressure exerted by the side plates 179 on the record material.
After the check has been fed through the first two feed stations, the check enters the reversing section of the stacker by engaging the pressure roller 116 and the feed roller 115 (FIGS. 1 and 3). The construction and action of the pressure roller 116 are similar to those of the pressure roller 108. As shown, the pressure roller 116 is rotatably supported intermediate the ends of a follower arm 117, which in turn is rot-atably supported on a stud 118, mounted on the back panel 99. One end of the follower arm 117 rotatably supports another pressure roller 119, while the other end of the follower arm has a flange portion 120, which is engaged by a tension spring 121, supported by the top guide 104. An adjustment screw 122, supported by the flange 120, is used to adjust the tension which is applied to the follower arm by the spring 121. It will be seen from FIGS. 1 and 3 that the pressure roller 116 is positioned in relation to the feed roller 115 by the position of the pressure roller 119 on the follower arm 117. The pressure roller 119 does not require any side plates, due to the fact that both the pressure roller 119 and its associated feed roller 123 are made of nylon. Thus, when the pressure roller 119 is in contact with the feed roller 123, the pressure roller 116 will be positioned adjacent to but not in contact with the feed roller 115. In this position, the side plates of the pressure roller 116 will overlap the feed roller 115, thus engaging any record material that is fed through the check guide 103.
Referring to FIG. 3, it will be seen more clearly that, as the check engages the pressure roller 116, the roller and the follower arm 117 will be rocked clockwise upwardly against the tension exerted by the spring 121. This rotation of the follower arm will also rock the pressure roller 119 from engagement with the feed roller 123 to a position shown in solid lines in FIG. 3, thus allowing the check to follow a path indicated by the line 18 4. The check will continue along a path between the top guide 104 and a lower guide 124. This direction of feed will continue as long as the check is engaged by the feed roller 115 and the pressure roller 116. As soon as the check has passed these rollers, the pressure roller 116 will rotate counter-clockwise to its non-operating position under the influence of the tension spring 121. This movement will simultaneously rock the pressure roller 119 into engagement with the check, forcing the check into contact with the feed roller 123. The feed roller 123 is driven in a direction opposite to that of the feed roller 115, which results in the reversal of the direction of feed of the check as it leaves the feeding influence of the roller 115. Since the feed roller 123 is rotating in the opposite direction to that of the feed roller 115, the reversing action of the check will occur immediately after the check has passed the feed roller 115. As a practical matter, the check will be in contact with the feed roller 123 intermittently as it is being fed by the feed roller 115, due to the fact that the distance separating the two feed rollers is less than the normal length of the check being fed. Since the pressure roller 119 is out of contact with the check, the roller 123 has no effect until the pressure roller 119 forces the check into contact with the roller 123 upon the disengagament of the check from the rollers 115 and 116, as explained previously.
As shown in FIG. 3, the means for driving the feed roller 123 consists of an intermediate gear 125 and a pressure roller 126, which is driven by the feed roller 115. Referring to FIG. 1, the intermediate gear 125 is shown rotatably supported on a stud 127, mounted on the back panel 99. Also rotatably supported on the stud 127 is an arm 128, one end of which is biased in a counterclockwise direction by a spring 129, attached to a stud 130, mounted on the back panel 99. The other end of the arm 128 rotatably supports the pressure roller 126. Due to the biasing action of the spring 129, the pressure roller 126 is continuously urged into contact with the feed roller 115. Also mounted on the feed roller 123 and the pressure roller 126 are gears 175, which are engaged by the intermediate gear 125. From this arrangement, it will be seen that, when a check is disengaged from the rollers 115 and 116, the feed roller 123, cooperating with the pressure roller 119, will feed the check into engagement with the pressure roller 126 and the feed roller 115. Thus the check is fed in a direction opposite from its original direction and is now ready to be fed into a collecting bin.
Located immediately below the rollers and 1 26 is a check deflector 131, mounted on a shaft 132. The shaft 132 is journaled in the back panel 99. Referring to FIG. 2, there is shown attached to the shaft 132 an arm 133, the other end of which has attached thereto a link 134. The link extends horizontally across the back panel, where it engages a lever 135, pivotally supported on a stud 136, mounted on the back panel 99. In FIG. 1, there is shown located below the check guide a solenoid 106, mounted to the back panel 99 by means of screws 137. The plunger of the solenoid 106 is connected to a link 138, the other end of which is pivotally connected to the lever 135 through a slot 139, located in the back panel. The solenoid is controlled from the parent machine and, when energized, will rotate the check deflector 131 by means of the linkage described above to a position which will deflect the check either into an upper check bin, formed by the side panels 140, or into a lower check bin, formed by the side panels 141.
Referring to FIG. 1, the check deflector is shown in a position to deflect the checks into the upper bin. Since the constructions of both bins are identical, the description in this application will be limited to the upper bin only.
The check, after being deflected by the deflector 131, enters the upper check bin through a check chute comprising a top guide 143 and a bottom guide 144. As shown in FIG. 6, the outer edge 145 of the top guide 143 is canted to the left, While the lower guide 144 is substantially cut away, leaving only a narrow ridge, on which the check is guided to a stacked position.
Located adjacent the top guide 143 are two feed rollers, 146 and 148. The first feed roller, 146, cooperates with a pressure roller 147, similar in construction to the pressure roller 108, described previously. As shown in FIG. 6, the feed roller 146 is olfset in relation to the direction of feed of the checks as they leave the check deflector 131. Due to this arrangement, the checks, when engaged by the feed roller 146, will be urged into engagement with the back panel 99, thus providing positive control over the feeding of the checks by the roller 146. The checks are then fed into contact with the feed roller 148. It will be ntoed that the feed roller 146 has a flat surface 180. By this construction, the feed roller 146 will intermittently feed the checks until they are engaged by the feed roller 148, at which time the flat portion of the roller 146 will allow the checks to be positioned by the feed roller 148.
Referring to FIG. 6, it will be seen that the feed roller 148 is so positioned in relation to the direction of travel of the checks that, once the checks are engaged by the roller 148, they will be rotated counter-clockwise and positioned on a check shoe 149 ('FIG. 1). As seen in FIG. 1, the check shoe 149 is slidably supported at one end by a pair of cross links 150, while the other end of the shoe is attached to a pair of cross links 151. A spring 152 (-FIG. 5), mounted on the cross links, urges the check shoe into engagement with the feed roller 148. Thus, as the checks are fed onto the shoe, they will be urged into engagement with the roller 148, thereby allowing the roller to exert a more positive control over the positioning of the checks. Under the guidance of the roller 148, the checks will be so positioned on the shoe 149 that their leading edges will abut the side panel 153 of the check bin, while the inside edges abut the back panel 99. This provides for the alinement of the edges of the checks as they are stacked on the shoe. It will be seen that, due to the rotation of the check as it reaches the end of the full length of travel, interference from the checks stacked previously will be reduced to a minimum, thus insuring that the checks will be aligned on their leading edges, as required.
It should be noted from FIG. 1 that, as the checks are stacked on the shoe 149, the loose end of a check will droop over the edge of the shoe, due to the fact that the length of the shoe is much shorter than the length of the check. Because of this construction, any check which is crumpled or bent will not interfere wtih the stacking of a succeeding check. Thus the checks will be stacked, and their leading edges will be alined, in such a manner that they may be removed from the stacker and inserted into a sorter without the requirement of jogging the checks to insure that the checks are in the required position.
Referring to FIG. 1, there is shown located in the check chute a sensing arm 154, attached to the switch arm 155 of a micro-switch 156, mounted on the back panel 99. The function of this switch is to act as a jam detector signalling the jamming of a check in the check chute. Each time a check is fed through the check chute, the arm 154 will be rotated clockwise to open the switch 156, which drops out a relay (not shown) located in the parent machine. In order for the next check to be processed, the relay must be energized, which normally occurs as the switch 156 is closed upon the passing of a check over the arm 154. When a check becomes jammed in the chute, the switch 156 will remain open, thus preventing operation of the parent machine. Such a condition will give suflicient notice to the operator of the jammed condition of the stacker, thus allowing the operator to take steps to eliminate this condition.
In the case where the check deflector 131 is positioned to deflect the check into the lower bin, the checks will enter a check chute formed by a top guide 157 and a lower guide 158. The check will be transported along the chute by the feed rollers 107, 146, and 148 in the manner described in connection with the upper bin. Also located in the chute is a jam detector device, of the same construction as that disclosed above.
Referring to FIG. 2, there is shown the driving means of the feed rollers utilized in the stacker. Located hori zontally at the top of the stacker is a coupling shaft 159, one end of which is connected to the drive shaft of a motor (not shown) located on the parent machine. The coupling shaft is rotatably supported by a plurality of support blocks 160, each block being mounted on the back panel 99. Mounted on the coupling shaft are a series of bevel gears 161. Each bevel gear 161 drives another bevel gear 162, pinned to one end of a shaft 163 (FIG. 1), the other end of which supports a feed roller. Operation of the coupling shaft by the motor will drive each feed roller through the above gear arrangement. Another bevel gear, 181, also located on the coupling shaft 159, drives a gear 182, which is mounted on a shaft 164, to which is connected a pulley 165. It will be seen from FIG. 2 that each of the feed rollers associated with the feeding of the check after it has left the check deflector has a similar pulley 166. As shown, one set of pulleys is driven by means of a belt 167, while the other set of pulleys is driven by a belt 168. Associated with these two belt systems are a pair of idler pulleys 169, with slide means '170 for adjusting the tensions of the belt systems. Thus each feed roller is driven at a constant speed by the motor located in the parent machine.
