United States Patent 3,172,656 SHEET JOGGING MECHANISM FOR BELT TRANSPORTFNG IVIEANS Luis Mestre, 305 E. 46th St., New York, N.Y. Filed Jan. 18, 1963, Ser. No. 252,529 31 Claims. (Cl. 271-48) The invention relates to a jogging mechanism for jogging a plurality or book of sheets to bring them into precise lateral alinement and to bring the ends of the book of sheets into more accurate end to end alinement. This jogging mechanism is used on the Mestre Collating Machine S.N. 191,141, filed April 30, 1962, now Patent No. 3,108,797, dated October 29, 1963. This collator provides a plurality of storage pockets, each containing a pile of one sheet, and ejects one sheet from each storage pocket and delivers this book of sheets in overlapping but spaced end to end relation to a transporting means having sheet stop means. The sheets of the book are brought into approximate end to end alinement at the stop. It is now desired to staple the book of sheets in at least one corner While the sheets are halted at the stop means before passing the book to a deposit platform. When the sheets are stapled on the transporting means at the stop, it is desirable that the sheet be brought into more precise lateral alinement and more precise end to end alinement. The jogging mechanism to be described herein efiects this more precise alinement.
It is an object of the invention to construct a jogging mechanism including a lateral jogging means and a longitudinal jogging means for a book of sheets which have been halted at a stop in the transporting means following collating of the sheets.
Another object of the invention is to provide jogging mechanism as above in which the lateral jogging means are adjustable laterally so that sheets of different widths may be accommodated.
Another object is to provide jogging mechanism in which the end or longitudinal jogging means is adjustable longitudinally so that sheets of different lengths may be accommodated.
Another object is to construct a combination of a roller longitudinal alining means and a longitudinal jogging means.
A further object is to construct an improved roller alining means for longitudinal alinement.
A still further object is to construct a jogging means for a book of sheets in which adjustability is made without change of the operating means which jogs the jogging means.
Another object is to provide a combination of the above means for both lateral and longitudinal jogging of a book of sheets.
Other objects of the invention will be more apparent from the following description when taken in connection with the accompanying drawings illustrating a preferred embodiment in which:
FIG. 1 is a front view of the transporting means of the collating machine and the lateral and vertical joggers;

FIG. 8 is a view showing the drive connection between sheets transporting belts.
In the collator above identified a plurality of storage pockets are provided, each of which has a different sheet or page of a book. Some of the numerals used herein are those used in the prior application for the same structure. Means are provided to eject one sheet from each pocket at the same or approximately the same time and feed the same in overlying relation but with their ends progressively spaced apart a distance less than sheet length such as two or three inches. These ejected sheets forming one book are fed in spaced overlapping relation to the sheet transporting means 22. A frame 21, 21a of necessary. form is provided, which carries pairs of feed belts 141 and 158, two pairs being shown. In the collator of the prior application the transporting means are preferably inclined. Each belt 141 passes over rollers 145 (FIG. 8) at the top of the frame 21 and over roller 147 at the bottom of the frame from which each belt passes to the collating operation and then back to roller 145. The belt is driven directly by roller 145. The set of feed belts 158 pass over a roller 159 around roller 142 at the top of the frame, over roller 145 and pass around roller 161 at the bottom. The inner span of the belts 153 are driven downwardly, as viewed in FIG. 1, by contact of each belt 158 with its cooperating belt 141 and particularly by the arcuate contact, provided between the belts around the driving roller 145. The path of the sheets is longitudinally between the belts 141 and the contacting portion or inner span of the belt 158. The roller 145 and hence the belts of the transporting means are continuously driven by means including a belt and pulley 153. A supporting plate 166 carried by the frame gives additional support to the sheets when being transported by the belts.
A stop operating means 165a controls a stop means 165 which is moved into and away from the path of movement of these sheets, which stop means is engaged by the lowermost or forward edge thereof and halts the sheets thereagainst. It is while the book of sheets are halted by the stop means that jogging for alinement and stapling takes place. Any form of stop means may be provided. Preferably the stop operating means 165a depresses the stop means from the path of the book of sheets so that the book may be advanced thereover by the transporting belts to a deposit platform at the end of the transporting means after having been jogged into alinement and stapled. This stop operating means is described in detail in the above identified prior application and so far as the jogging mechanism therein is concerned it need only be mentioned that the stop means is raised or brought into the path of the sheets until the book of sheets are jogged into alinement and stapled, after which the stop means is depressed or retracted out of the path of the sheets and the belts of the transporting means carries the book to a deposit platform. In the event that there is one or more sheets missing or one or more extra sheets included in the book, as determined by gaging means located at the stop position, the book is carried to a rejection bin.
The alining mechanism includes longitudinal jogging means and lateral jogging means. The longitudinal jogging means is mounted on a carriage 25, FIG. 6, desirably adjustably mounted on the frame 21 and particularly on side plates 21a forming a part of the frame. Clamps 27 lock the carriage in adjusted position. This carriage also carries a roller longitudinal alining means to be described hereinafter so that it too is adjusted longitudinally with the adjustment of the longitudinal jogging means.
The longitudinal jogging means includes a jogging finger 30, FIG. 3, which is mounted for vertical movement between the sides 31 of a bracket 32, carried by the carriage 25. This jogging finger carries a pin 33 which is in a slot 34 carried by a bell crank lever 35 which lever is pivotally mounted on a pivot 36 carried by a bracket 32. The arm 37 of this bell crank lever carries a roller 38 mounted upon a pin 39. The roller engages the edge of a finger operating bar 40 having a pair of spaced inclined slots 41 therein in which is received a pin 42 carried by the frame 21 or particularly by cross bars forming part of the frame, and a bracket 49. Upon vertical movement of the operating bar, it also moves laterally by virtue of the inclined slots and pivots the bell crank lever to move the jogger 30 longitudinally into engagement with the upper or rear edges of the sheets of the book and jog them into alincment against the stop means 165a. The inclined slots 41 may be carried by one of the parts including the finger operating bar 40 about the frame and the pins 42 carried by the other part.
Means are provided to move the operating bar longitudinally, as a consequence of which the operating bar moves laterally in a parallel motion through the camming action of the inclined slots 41 and the pins 42 received in the slots. This longitudinal movement of the operating bar 40 is secured by means of a link 45 secured to the bar at one end thereof by a pin 44 and the other end of the link is secured by pin 46 to a lever 47 carried by a pivot rod 48 and rotatably mounted in the frame 21a and a bracket 49 secured to the frame in any suitable manner. The shaft 48 carries a lever 50, which is oscillated in time sequence with respect to the other operations of the collator and particularly the stop means. The lever 56 carries a roller 51 on the end thereof.
An operating connection is provided between the lever and the drive or cam shaft 26 mounted in the collator frame 20 and driven by a collator motor, in order to oscillate the jogger in timed sequence with the other operations of the collator and particularly with the projection of the stop means 165 into and away from the path of movement of the sheets. In other words the longitudinal jogger is oscillated after the stop means 165 has been moved into stop position and before it is retracted from stop position. It is during the same period but after jogging that the book of sheets is stapled. The lever 50 is operated by a flange 54 carried by a link 55, one end of which is connected by a pivot pin 56 to a lever 57 pivotally mounted on a pivot 58 carried by the frame 21.
Connecting means is provided to pivot the lever 57 and this means is constructed so that the frame 21 may be swung away from the collator. The operating connection is secured by having a roller 59 carried by the lever 57 which is engaged by a lever 60 pivotally mounted on the collator frame 20 on pivot 61. The lever is connected through a pin 62 to a link 63, the lower end of which link carries a cam roller 64 which engages a cam 65 secured to the drive or cam shaft 26. The cam 65 is shown with a single raised portion so that one oscillation of the jogging mechanism occurs for each revolution of the shaft. The lower end of the link 63 is guided by a swing link 66 pivoted to the link by a pin 67 and the other end of the link is pivotally mounted on a pivot 68 carried by the frame.
Means are provided, FIG. 4, to move the longitudinal jogging means or finger into the path of movement of the sheets and after jogging is then retracted or depressed away therefrom so that the next book of sheets passes thereover. One of the parts including the fingers 30 and the bracket 31 includes an inclined slot means for moving the jogging finger away from or below the path of movement of the sheets and slot engaging means is carried by the other part engaging in the inclined slot means. In the construction illustrated the inclined slot means includes a slot 72 carried by each side 31 of the bracket means 32. The jogging finger 30 has spaced angularly extending flanges 73 received between the sides 31. The flanges carry a pin 74 each end of which engages its respective slot to form slot engaging means. This structure shifts the jogging finger 30 downwardly below the path of movement of the sheets in one direction of longitudinal movement of the finger and upwardly upon movement in the other direction. Preferably each inclined slot has a straight or parallel portion 75 at the end thereof so that when the jogging finger 30 has been brought fully into the path of movement of the sheets, the finger moves horizontally or parallel with the sheets in performing the. jogging of the sheets. The longitudinal jogging finger and" its connections are returned to initial position by a spring 76 connected between the finger lever and the bracket 32.
The lateral sheet jogging means, FIGS. 1 and 5, includes a pair of spaced jogging rails 79 extending longitudinally with respect to the transporting means. Each rail is secured to its slide bar 80, FIG. 5, by a flange 87. Each rail is oscillated outwardly and a spring 81 connected with the two slide bars pulls the bars and rails inwardly towards each other. Each slide bar carries an adjusting slot 82 in order to adjustably secure each jogging rail to its slidebar by means of suitable clamping means 83 engaging the flange 87, and slide bar. These jogging rails therefore may be spaced apart depending upon the width of the sheets to be jogged or alined. The slide bars are mounted for lateral movement on the frame 21 or particularly. on a cross bar 84 which carries guide pins 85 which are received in slots 86 carried by each slide bar 80. The cross bar 84is secured to the side plates 21a and hence forms a part of the frame.
Operating means is provided to oscillate each slide bar and its' rail laterally. The means particularly illustrated is a cam 89 pivotally mounted on a pivot 90 carried by the cross bar 84 which cam is located between spaced but adjacent inner ends of the slide bars 30. Upon turning of the cam both slide bars and their jogging rails are oscillated laterally outwardly and upon return of the cam to initial position the spring 31 pulls the slide bars and rails inwardly as well as maintaining the adjacent ends of the slide bars against the cam.
Cam operating means is provided to oscillate the lateral jogging cam 89, which means includes a link 93 pivotally secured by a pin 94 to the cam 89, which link is slidably mounted in a bushing 95 secured to a side plate 21a. The link 93 carries a roller 96 mounted on its end on a pin 97, which roller engages a bell crank lever 98. This lever is pivotally mounted on the frame on a pivot 99 carried by a bracket 102 secured to the frame and the other arm 100 of the bell crank lever carries a 0 pin 101 connecting the lever to the link 55. The oscillation of the jogging cam 89 and the jogging rails 79 is, therefore, secured from the same cam 65 which oscillates the longitudinal jogging finger 30. With a single projection on the cam 65, the lateral jogging occurs once for each revolution of the shaft 26.
It is desirable that the lateral jogging means have means to restrain the longitudinal edges of the sheets from displacement away from the other sheets. This edge restraining means includes a space bar 104 for each jogging rail which space bar is secured to its rail Why a screw 105. The space bar has its upper end angled outwardly to guide the longitudinal edges of the sheets between the jogging rail and the space bar. The space bar may be removed and substituted by a jogging unit with long studs to' provide for sheets narrower than the range of adjustment provided.
It has been mentioned that the collator delivers a book of sheets to the transporting means with the leading edges of the sheets in longitudinal spaced relation between the arraese feed belts 141 and the inner band or span of the feed belts 158. Since the first and the last sheet of a book of sheets is in direct contact with one of the feed belts, these sheets are positively moved thereby into contact with the stop means. Usually the frictional engagement between the sheets carries each of the intermediate sheets against or adjacent to the stop. This does not always occurs, however, so that a roller alining means, FIGS. 6, 7, is provided just beyond the trailing edge of the sheets. This roller alining means engages any sheet or sheets which may not have been fed into contact with or adjacent to the stop and feeds them into this position. This assures that the trailing edges of the sheets are not projecting rearwardly far enough to interfere with the more precise jogging of the longitudinal jogging finger 30. Preferably the roller advancing or alining means is driven by the feed belts 158. The roller alining means may be that described in the above identified application. The roller alining means to be described is an improvement on that of the earlier application. It is carried by the carriage 25, so that it is adjustable longitudinally with the longitudinal jogging finger in order to accommodate for sheets of greater or lesser length making up the book.
The roller alining means includes back-up roller means comprising a pair of rollers 111 rotatably mounted on a rod 112, which rod is mounted in slots 109carried by the carriage 25 for movement towards a drive roller. Springs 113 propel the rod and rollers upwardly as viewed in FIG. 6. The periphery of the back-up roller 111 is in the region of the level of the sheets positioned between the transporting belts 141 and 158. Alining or advancing roller means such as two rollers 114 are rotatably mounted such as on shaft 115 which is carried by a bracket 116 secured to the carriage 25. There is an advancing roller 114 for each of the back-up rollers 111 and in alignment or contact therewith. The sheets of the book pass between the rollers 111 and 114.
Advancing or feed rollers 114 are rotated by any suitable means and conveniently from the transporting belts. The roller 114 is suitably secured to a driving roller 117. This may be a direct connection, as shown or by securing both to the shaft 115. The driving roller 117 is smaller in diameter than the advancing roller 114 to provide clearance for the transporting belt 158. The driven roller 117 and hence the advancing roller 114 must be rotated in a direction to feed sheets downwardly between the transporting belts against the stop means or adjacent thereto. The rollers 111 and 114 are located just above the length of a sheet measuring from the stop means. Any sheet or sheets which have not been advanced by the transporting belts into contact with the stop means and hence project rearwardly therefrom are engaged by the advancing rollers and advanced toward the stop means. The advancing roller 114 may be rotated from the transporting belt 158 and particularly the upper pass or band of this belt. Since this upper pass is moving upwardly, the periphery of the advancing roller on the opposite side thereof is moving downwardly, as viewed in FIG. 8. The driving roller 117 is therefore held in engagement with the upper pass or band of this belt.
Means are provided to press the upper pass of the transporting belt 158 into contact with the periphery of the driving roller 117. This means includes a pressure roller means comprising a pair of spaced pressure rollers 121 rotatably mounted on a shaft 122, which shaft is carried by a pressure roller bracket 123. This bracket is pivotally mounted on the bracket 116 by pins 124. The pressure rollers 121 are spaced from the driving rollers 117 and shown particularly as forwardly thereof, so that the upper pass of the belt 158, in passing over the driving roller 117 and under the pressure roller 121 provides an arcuate contact of the belt 158 with the driving roller. Suitable means are provided to press the pressure roller 121 against the belt; that particularly shown includes a screw 125 carried by an arm 126 secured to the bracket 6 116 and located so that the screw engages the bracket 123. A pin 127 is carried by the bracket 116 adjacent to each roller 114 and the path of the sheets and assures that the sheets follow the transporting belts.
Any sheets which project beyond the trailing edge because they have not been brought into contact with the stop means or adjacent thereto are engaged by the feed rolls and advance into contact therewith or adjacent thereto. There are, therefore, no rearwardly projecting ends of the sheets in the path of the longitudinal jogging means to interfere therewith. As a consequence the longitudinal jogging means jogs the sheets so that the forward edges of the sheets are brought into contact with the stop means so that they are accurately alined to be stapled in this position.
In order to assist in guiding the carriage 25 for adjustt merit, a guide bar 130 is secured to each side plate 21a and engages an edge member 134 carried by the carriage. Preferably too, each guide bar has rack teeth 131 which are engaged by a gear 132 secured to a shaft 133 so that adjustment of the carriage is smoother. Also the supporting plate means 166 will have laterally extending grooves 135 to receive the ends of the jogging rails 79 to bring the end surface into alinement with the top of the supporting plate means 166.
This invention is presented to fill a need for improvements in a sheet jogging means. It is understood that various modifications in structure, as well as changes in mode of operation, assembly and manner of use, may and often do occur to those skilled in the art, especially after benefiting from the teachings of the invention.
