HEATING MEANS FOR CASING-IN MACHINE Filed Oct. 4, 1962 INVEN TOR. JAMES H. THORP ATTORNEYS United States Patent 3,201,810 HEATING MEANS FOR CASING-IN MACHINE James H. Thorp, Hartford, Conn, assignor to The Smyth Manufacturing Company, Bloomfield, Conm, a corporation of Connecticut Filed Oct. 4, 1%2, Scr. No. 228,498 Claims. (Cl. 11-3) This invention relates generally to casing-in machines wherein book components comprising fillers and cases are assembled and secured together. More particularly, the invention is directed to the problem of slow set up or drying of the adhesive employed to secure fillers and cases in assembled relationship.

In conventional casing-in machines, book cases and fillers are automatically assembled with adhesive therebetween and the assembled books are then pressed at least for a short time to maintain the books shape while the adhesive begins to set. The time available for this pressing operation in casing-in machines is usually quite limited and the books are ordinarily passed to a pressing and forming machine wherein substantial time elapses in the complete or substantially complete set up or drying of the adhesive. The time delay in set up or drying has been a vexing problem in that the use of relatively bulky and complex pressing and forming machines has been necessary and yet detrimental effects have been encountered in the over-all time required for the manufacture of books.

It is the general object of the present invention to provide a casing-in machine including one or more heating means adapted to heat book components prior to discharge from the machine whereby to expedite set up of the aforesaid adhesive and thus to substantially lessen the task of an associated pressing and forming machine and to reduce over-all set up time.

A further and more specific object of the invention resides in the provision in a casing-in machine of heating means adapted to heat at least one component of each book prior to assembly of the book components.

A still further object of the invention resides in the provision of a casing-in machine of the type mentioned wherein heating means is provided for heating both components, case and filler, of each book prior to assembly.

The drawing shows a preferred embodiment of the invention and such embodiment will be described, but it will be understood that various changes may be made from the construction disclosed, and that the drawing and description are not to be construed as defining or limiting the scope of the invention, the claims forming a part of this specification being relied upon for that purpose.

' Of the drawing:

The single figure of the drawing is a diagrammatic view of a casing-in machine including heating means in accordance with the present invention.

The invention is equally adaptable for use in other types of casing-in machines but its advantages are particularly well illustrated in a casing-in machine of the type disclosed in the Schramm and Clark Patent No. 1,765,349 dated July 17, 1930 and entitled Casing-In Machine. Accordingly, the diagrammatic illustration of the drawing is based upon the type of machine disclosed in Patent 1,765,349 and only elements of the casing-in machine operable directly on book components are shown therein. The disclosure of the patent is relied upon for description and illustration of operating means for the elements shown in the drawing and for description and illustration of other portions of the machine which may be deemed necessary for a full understanding of the invention.

Referring now particularly to the drawing, it will be observed that a case storing magazine is indicated generally at It The magazine 10 is adapted to hold a plural- 3,201,8lh Patented Aug. 24, 1965 ity of cases 12, 12 in vertically stacked relationship with their inner sides facing downwardly and said magazine includes four vertically extending corner members 14a, 11, c and d partially shown in the drawing. Means for supporting the cases 12, 12 in the magazine 10 is provided at the bottom of the stack and said means may comprise a pair of spaced parallel and generally horizontally extending guide and support bars 16, 16.

The guide and support bars 16, 16 extend forwardly from the case storing magazine It) to a case Forming and reasing Station A so that cases may be successively advanced therealong from the bottom of the stack in the magazine 15). As will be seen the guide and support bars 16, 16 serve to support advanced cases at the Forming and Creasing Station A. From the Forming and Creasing Station A, the guide and support bars 16, 16 may extend forwardly to an assembly Station B for the successive advance of cases therealong.

Means for successively advancing cases along the bars 16, 16 comprise a first pair of

pusher elements

18, 18, one shown, each comprising a head 29 and a pin 22. Each pin 22 has associated therewith a biasing spring 24 which urges the pin and its head upwardly with respect to a driving rack 26. As shown, the head 20 is in engagement with a lowermost case 12a and the pin and head are in their upper positions. The rack 26 is reciprocated generally forwardly and rearwardly by pinion means not shown whereby to cause the

pusher elements

18, 18 to advance a case such as 12a to the Forming and Creasing Station A and to return for the subsequent advance of a succeeding case. On a return stroke of a pusher element its head and pin 20, 22 may be depressed by engagement with the succeeding or lowermost case in the magazine 10 whereby to pass therebeneath and to engage the trailing edge thereof.

For advancing cases such as a case 12b from the Forming and Creasing Station A to the Assembly Station B, a second pair of pusher elements 23, 28 are provided. The

elements

28, 28 are or may be substantially identical with the aforesaid elements 13, 13 and said elements may include heads 30, 39, pins 32, 32, and

springs

34, 34 and have associated therewith

racks

36, 36. Reciprocation of the

racks

36, 36 by pinions not shown will obviously provide for forward and return or working and idle strokes of the said pusher elements.

At the Forming and Creasing Station A, a case such as 12b is formed and creased along its back portion by means of a vertically movable mandrel 38 disposed therebeneath and vertically

movable creaser bars

40, 40 disposed there above. The case may be supported at least initially by the aforesaid guide and support bars 16, 16.

On completion of the forming and creasing operation, a case such as 12b is advanced to the position of the case at the Assembly Station B by means of the

pusher elements

28, 28. At the Assembly Station B, a case such as 120 may be supported in readiness for assembly with a filler by means of spaced generally U-shaped horizontally extending

members

42, 42. The

members

42, 42 have

lower portions

44, 44 respectively supporting opposite side edge portions of the case 120 and

upper portions

46, 46 of said members may serve as an initial hold-down device for said side edge portions as will be seen.

Fillers, adapted for assembly with cases such as 12c, are supplied to the Assembly Station B by

saddle plates

48, 48 intermittently and in timed relationship with the aforesaid means for advancing the cases to said Station. The lowermost saddle plate 48 is shown with a filler 5t] mounted thereon and is indicated as being movable upwardly along a substantially vertical path by arrow 52. Appropriate loading means, not shown, successively load fillers such as 50 on

saddle plates

48, 48 at a loading Station disposed beneath the lowermost plate shown. The plates are then moved upwardly as by means of an upwardly moving run of a sprocket chain indicated diagrammatically at 54 whereby to provide for the application of adhesive to the fillers and for assembly of the pasted fillers with cases at the Assembly Station B. Paste rolls indicated generally at 56, 56 are adapted for inward and outward movement along generally horizontal lines whereby to engage the sides of fillers such as 50 and to apply paste thereto.

A pasted filler such as 50, in upward movement of its associated saddle plate 48 engages a case such as 120 at the Assembly Station B. As mentioned, the side edge portions of the case are held down at least initially by the

portions

46, 46 of the

aforesaid bars

42, 42. Thus, the case begins to fold about the filler. Generally U- shaped folding bars 58, 53 further tend to hold down the side portions of the case as the filler progresses upwardly whereupon the case is completely folded about the filler in asembled relationship therewith.

With case and filler in assembled relationship, further upward movement of a saddle plate 48 at the urging of the sprocket chain 54 causes an assembled book such as 60 on the uppermost saddle plate 48 to pass between similar

opposing presser rolls

62, 62. The

presser rolls

62, 62 may be spring biased inwardly as shown diagrammatically at 64, 64 whereby to automatically engage and press opposite sides of the case of an assembled book in passage therebetween.

After passage through the

presser rolls

62, 62, books may be removed from

saddle plates

48, 48 by means of suitable unloading means, not shown, and thereupon discharged from the casing-in machine.

Now from the foregoing it will be apparent that a casing-in machine generally described above and fully disclosed in the aforesaid patent includes means for successively transporting fillers along a first predetermined and generally vertical path to an Assembly Station. The machine also includes means for successively transporting cases along a second predetermined and generally horizontal path to the Assembly Station and, finally, a

means is provided for successively transporting assembled books away from the Assembly Station. In accordance with the present invention, at least one component of each assembled book is heated in a casing-in machine whereby to expedite set up of the adhesive employed to secure the components of the book in assembled relationship. More specifically, heating means is provided adjacent at least one of the aforesaid predetermined paths of component and book movement and, in the embodiment of the invention shown, a plurality of heating means is employed whereby each component of each book is heated prior to assembly and the assembled book is thereafter heated prior to discharge from the machine. The heating means employed may vary widely within the scope of the invention but quartz lamps are utilized in each of several locations in accordance with the presently preferred practice.

Heating means indicated generally at 66 comprises a bank of quartz lamps 68, 68 disposed generally horizontally beneath the aforementioned magazine 10. As will be apparent, the inner side of the lowermost case (such as 1211) will be heated by the said lamps. The lamps are so arranged as to heat substantially the entire surface of the innerside of each case prior to advancement of the same to the Forming and Creasing Station A.

At the Forming and Creasing Station A, there is provided a heating means indicated generally at 70 and comprising quartz lamps 72, 72. The lamps 72, 72 are also arranged to heat substantially the entire inner surface of each case and yet not interfere with the aforementioned forming and creasing means.

At the Assembly Station B, there is provided a heating means indicated generally at 73 and comprising quartz lamps 74, 74. Lamps 74, 74 are aranged to heat substantially the entire inner surface of each case at the said Station.

Adjacent the lowermost saddle plate 48 there is provided a heating means indicated generally at 76, 76 and which comprises

quartz lamps

78, 78 aranged in opposing pairs to heat substantially the entire outer side surface of each filler 50.

Finally, heating means 80, 80 disposed above the

aforementioned presser rolls

62, 62 include

quartz lamps

82, 82 arranged in opposing pairs to heat substantially the entire outer side surface of each assembled book 60.
