45 Referring more in detail to the drawings:
I designates a machine for tip gluing adiacent edges of superimposed sheets of paper or like material as in the binding of books, insertion of plates in books, preparation of circulars,
50 and like articles.
The machine I includes a table portion 2 that is carried at its ends by pairs of legs 3, 4 and 5, 6 which are braced to longitudinal side flanges I of the table by diagonals 8. Carried 55 at one end of the table is a work supporting shelf 9 including a plurality of slats i extending in the longitudinal direction of thevtable and which are adapted to be interposed relatively to each. other for locating aguide strip II on. one of the slats in alignment with a tipping mechanism carried on the table portion of the machine, later described.
The work supporting shelf is preferably supported in horizontalalignment by braces [l2 connecting the shelf with the legs 3 and 4. Carried by the sides of the shelf are work sup- I porting wings I 3 and II which are adapted to carry stacks of material which are to be run through themachine.
The tipping mechanism includes a feeding head comprising upper and lower conveyor belts l5 and I6. arranged in the same vertical plane and having upper and lower runs I1 and I8 moving in contact with each other whereby the sheets to be tipped are moved through themachine and held in correct relationwhile the tipping mechanism is operating thereon to secure the sheets together. The lower conveyor belt has its upper run I! operating in a longitudinal slot I9 extending the length of the. tabletop 2 and is supported with its upper face in the plane. thereon on a series of rollers 2| thatare mounted on pins 22 having their ends supported in longitudinal flanges 23 and 24 dependingfrom the sides of the slot "L. as best shown into Figs. 4and 5. v i V Y The lower run l8 of the upper belt is retained in yielding contact with the upper run of the lower belt by a-series of rollers 26 carried by spaced longitudinal bars 21 and 23 wh ch are suspended over the table by means of goose neck brackets 29 and 30.. The intermediate rollers 26 are rotatably mounted on shafts 3| having their ends movably mounted in slots 32 of the longitudinal bars 21 and 23 and are yleldingly urged against the belts by spring prv sed plungers 33 and 34 slidably mounted in cores 35 and 36 in the bars and having ends engaging in sockets 31 of the ends of the shafts.
The springs are loosely supported in the bars and have one end engaging the tops of the plunger and their opposite ends engaging plugs 39 that are threaded in the open upper ends of the bores 35 and 33.
The bars 21 and 28 are spaced apart to ac- 5o commodate-the width'of the belt and rollers by means of 'U-shaped brackets 40 in which are rotatably mounted vertically positioned screw threaded shafts II that are threadedlysupported in the horizontal arms 42 of the brackets to feed the sheets through the machine, but they also clamp the sheets in position for tipping so that they will not become disarranged when the sheets are acted upon by the tipping mechanism.
Owing to the fact that the sheets are positioned on the shelf, so that the edge of one overlies the place on the other to which it is to be secured, it is necessary to provide means for raising the edges of the upper sheet while glue or other suitable adhesive is applied to the lower sheet. This is accomplished bya shoe '44, the
detail construction of which is best illustrated in Figs. 7, 8 and 9. The shoe is preferably formed of flat sheet metal and includes av horizontal flange portion 45 that is supported above the table top a sumcientdistance to permit passage of the lower sheet thereunder as it is being advanced by the conveyor belts while the upper sheet is moved over the'upper facethereof as later described.
Extending along the outer edge of the flange portion is a vertical portion terminating at its upper edge in a laterally extending wing 41 terminating adjacent the side bar 21 in an attaching'flange 4., the attaching flange 40 being provided with key-hole slots 4! to engage headed studs 50 projecting from the side face of the side bar as best shown in Pig. 1.
The end II of the flange portion 45 adjacent the work supporting shelf is preferably rounded and is so located that the respective sheets may be inserted under and above the flange prior to engagement of the feeding belts therewith so as to assure that the lower sheet moves under the flange while the upper sheet moves on top of the flange. The opposite end of the flange 45 extends beyond the vertical portion 48 of the ,shoe and the side thereof adjacent the outer edges of the sheets is cut away as at 52 to accommodate a glue applicator It later described, so that the glue applicator can operate directly on the lower sheet which is advanced under the flange 45.
The extending-portion of the flange is provided with a vertical guard rail 54 extending along the side of the applicator and having its end connected with the vertical portion of the shoe as at 55 to provide an inclined vertical guide 56 whereby the edge of the upper sheet is guided therealong and prevented from striking against the applicator. s
In order to compensate for the projecting edge of the upper sheet whichnormally would extend beyond the conflnes of the guard 54, the opposite edge of the flange 4! is flanged upwardly from a point adjacent the end of the vertical portion 46. to the terminal end thereofas-at 51 and the upper end of the flange terminates in an outwardly curved and downwardly extending rolled portion 58 to form a rounded ledge 59 over which the edge of the upper sheet is drawn in curved form so that the outer edge of the sheet is retained from engagement with the guard 54. The advance end" of the ridge is curved upwardly from the plane of the flange 45 so that the edge of the sheet is lifted thereby.
In order to assure that the edge of the sheet is drawn or draped in rounded form over the ledge. 59, we provide a retaining guard 6i including a horizontal bar 62 extending in parallel relation with the vertical flange portion 51 and having its ends bent laterally as at 83 and 64 toconnect with the vertical flange portions 54 and 46, respectively.
-The forward end of the guard is preferably curved upwardly to. provide free entrance of the upper sheet thereunder to assist the curved nose 60 of the ledge in guiding the edge of the sheet.
The glue applicator includes a knurled'wheel 65 which is adapted to move in rolling contact with the upperface of the lower sheet alongside the vertical flange portion 54 of the shoe and which has its upper periphery operating through a slot 66 in a glue pot 61 whereirom 69, the shaft Ill being'positively driven by a pulley fixed on the outer end thereof and which is actuated'through a belt 14 operating thereover and over an aligning pulley 15 on the shaft 16 that is connected in driving relation with one of the pulleys of the upper conveyor belt, as shown in Fig. 1.
Projecting laterally from-the side bar 21 are horizontally spaced studs 11 and 18 carrying eccentrically mounted hubs l9 and 80 which support flexible pressing plates BI and 82. The plates II and 82 are preferably constructed of flat spring material and have one end located in pressing contact with the; work advanced through the machine and their opposite ends fixed to the hub 80 in peripheral contact therewith so that when the hubs are rotated on their respective studs and secured by set screws 83, the pressure of the plates is varied to suit the nature of the work. For example, when the attached ends of the plates are caused to reach about the periphery of the hubs greater tension" is established in the plates to provide greater pressure on the work. Similar pressing plates 84 are located at the delivery end of the bar 21.
In order to assure smoothing out of the upper sheet over the glued portion of the lower. sheet, the first wiper plate is preferably the width of the portion of the sheets projecting outwardly from the sides of the conveyor belts as shown in Fig. 5.
The following wiper plate 82 is of narrower width to contact'only atthe outer edges of the sheets or. over the portion carrying the glue so that after the upper sheet has been spread flatly over the lower sheet, greater pressure is 55 opposite edge will be in tippin relation to the tipping mechanism.
After the machine has been started, a lower sheet is placed upon the shelf with one edge thereof in abutting relation with the guide H and the forward edge under the rounded horizontal flange portion SI of the shoe.
An upper sheet is then placed on the lower sheet with corresponding edges abutting against the guide II and its forward edge supported above the rounded flat portion of the shoe. The superimposed sheets .are then advanced by hand until they are engaged by the conveyor belts which retain them in aligned position while the sheets are being advanced along the table with the edge of one in underlying relation with the flange portion 45 of the shoe and the other-in overlying relation therewith.
When the upper sheet engages and rides over the forward curved nose 88 of the forming ridge an engages under the curved end of the rail 6|, it is moved downwardly thereby in rounded overlapping relation with the rail so that the outer edge thereof is shortened suiliciently to permit its ready passage by the vertical guard portion 58 of the shoe.
As the underlying sheet passes the cut away portion of the flange 85, it is exposed to the action of the glue applicating roller so that continued advancement of the sheets effects application of a strip of glue along the lower sheet.
When the sheets are driven off the end of the shoe the uppersheet follows into contact with the lower sheet as illustrated in Fig. 12 and the curvature formed therein will gradually settle out until the edge lies in contact with the strip of adhesive. The sheets then are engaged by the first pressing plate which smooths out any of the curvature that may remain in the upper sheet, as shown in Fig. 14. The sheets are then engaged by the second pressing plate which presses the edge of theupper sheet in positive sealing contact with the strip of glue on thelower sheet to complete the tipping operation whereby the upper and lower sheets are securely attached along their upper side edges as shown in Fig. 16.
In order to positively deliver the completed work pieces from the machine, the end of the table opposite the shelf 8 is'provided with an oil-take conveyor 85 that' is supported on a frame 86 carried by the legs 5 and 8 and supplementary legs 81 and 88 respectively, the
spaced belts operating over rollers 89 and 88 I carried at the respectiveends of the frame 88.
From the foregoing, it is apparent that we have provided a machine which is of simple construction and which provides for the continuous tipping of superimposed sheets which have been preliminarily positioned in proper relation by the hands of the operator and that the preliminarily positioned sheets when moving through the machine are retained in position by the belts so that the adhesive is applied in the proper place on the lower sheet while the upper sheet is being supported therefrom out of contact with the adhesive applicator and that the sheets are retained in their desired alignment while the edge of the upper sheet is being restored to normal position on the lower sheet and pressed into sealing contact with the adhesive.
