Zahradnik, North Riverside, lill., assigner to A. B. Dick Company, Chicago, Ill., a corporation of Illinois Filed Get. 19, 1961, Ser. No. 146,285 12 Claims. (Cl. 27d-68) This invention relates to a scoring mechanism, and it relates more particularly to a scoring mechanism which is adapted to be integrated directly with a folding machine whereby paper and similar products passing from the folding machine will be scored simultaneously with the folding operation.
It has been the practice of the art to score paper and similar materials in order to facilitate bending of the materials during use and in order to provide a means for accurate folding of the paper along specific lines. It has also been found to be desirable in many cases to score paper and other materials which have been previouslyy folded. Existing means for accomplishing scoring have, however, been provided independently of a folding operation. Prior art devices have been associated with folding machines for the scoring of paper, but only as separate mechanisms with no essential cooperation existing between the folding and scoring operation.
It is an object of this invention to provide an improved scoring mechanism which will produce scoring marks in paper and similar materials in a highly eilicient manner.
It is a more particular object of this invention to provide a scoring mechanism which is adapted to be directly integrated with a folding machine whereby paper and similar materials passing from the folding machine can be scored in conjunction with the folding operation.
These and other objects of this invention will appear hereinafter and for purposes of illustration, but not of limitation, specific embodiments of this invention are shown in the accompanying drawings in which:
FIGURE l is a plan v-iew of an improved folding machine which is adapted to score paper or other material at the same time the material is being folded;
FIGURE 2 is a vertical section of the apparatus .of FIGURE 1;
FIGURE 3 is a detail View of guiding means employed in the device of this invention;
FIGURE 4 is a detail side view of the guide means shown in FIGURE 3;
FIGURE 5 is a detail side View of an improved scoring ring employed with the apparatus of this invention;
FIGURE 6 is an end view of the scoring ring shown in FIGURE 5; and
FIGURE 7 is an enlarged fragmentary section taken about the line 7 7 of FIGURE 4.
The present invention provides a sco-ring mechanism which generally includes a ring mounted on a pair of rollers which are used for transfer of material. The ring is provided with a diameter slightly in excess of the roller upon which it is mounted, and a ridge is formed in the ring for scoring of the materials as they pass between the rollers. A guide means is provided for adjusting and maintaining the position of the ring on the rollers. The guide means cooperates with the ring whereby the ring can be canted slightly with respect to its associated roller and driven laterally on the rotating roller in response to pressure on the guide means.
The guide means preferably comprises a Wheel positioned adjacent the ring and mounted for movement transversely of the rollers. A recess in the wheel interfts with the scoring ridge lon the ring whereby lateral pressure on the guide means will be transmitted to the ring and the ring canted thereby. It will be apparent that two or more of the scoring rings of this invention 3,157,398 Patented Nov. 17, 1964 ICC can be associated with one of the rollers which are adapte to transfer the material.
As noted, the scoring mechanism of this invention is eminently suitable for use in conjunction with a folding machine. The invention is particularly valuable when integrated with a folding machine of the type wherein material is passed into the machine, is buckled and then passed through a pair of rollers for folding of the paper. A machine of this type is described by Boblit et al., United States Patent No. 2,688,482, issued September 7, 1954. By providing the ring of this invention in a folding machine of this type, scoring of material can be easily accomplished Without in any way disrupting the normal folding operation and by making only a simple modification of the apparatus.
In the accompanying drawings, particularly FIGURES l and 2, there is shown a folding machine 10 of the buckle type. The machine includes a feed chute 12 which is provided for passing of paper into the folding unit feed rollers 14. The feed rollers 14 then transfer the paper into the folding unit generally designated I6. The folding unit includes a first pair of rollers 18 and 20 and a first fold plate 22 mounted in the construction by means of the bracket 23. The folding unit 22 includes a paper receiving channel 24 which terminates in a closed end 25.
A first pair of folding rollers are made up of the roller 20 and the roller 26. A second pair of folding rollers comprises the roller 26 and a roller 28. Intermediate the pairs of folding rollers there is provided a second fold plate 3@ mounted on the bracket 3l. This fold plate includes an open channel 32 terminating in a closed end 33.
A tinsel brush '54 is preferably provided between the second folding rollers and the runout belts 36. As is conventional, the brush removes static electricity from the paper prior to its transfer by the belts 36 onto the receiving tray 37.
Operation of the buckle type folder is provided by means of the motor 38 and belt itl adapted to drive the respective rollers. Paper fed from the chute 12 is adapted to pass between rollers 14 into the folding unit 16. The folding unit rollers 1S and 20 direct the paper into the channel 24 of the fold plate 22. The paper will buckle when the leading end strikes the closure 25 and the buckle will pass between rollers 2d and 26 proh viding a first fold in the paper. The folded portion of the paper will then become the leading end thereof and if a second fold is desired, the leading end will pass into fold plate 3d. Upon striking the closure 33, the paper will again buckle and this buckle will pass between rollers 26 and 2S and thence onto the runout table. If only a single fold is desired, a suitable baffle can be provided for blocking off fold plate Sil and for directing the first folded end between the rollers 26 and 28.
The scoring mechanism of this invention, which is adapted to cooperate directly in the folding operation, is shown in detail in FIGURES 3 through 7. The mechanism comprises a scoring ring 42 which is adapted to iit #around a roller 44. The ring is provided with an inner diameter slightly greater than the outer diameter of the roller.
The outer surface of the ring is formed with a ridge 46, the ridge having a rounded outer edge. The sides 48 of the ring taper toward the ring edges whereby the ring will be progressively thinner from the center to the side edges.
A guide means is adapted to ride on la cross bar 52 which is positioned parallel with respect to the roller upon which the ring is provided. The guide means comprises a bracket 54 which is movably mounted on the bar 52 and which can be releasably fixed with respect to the bar by means of a set screw 56. A spring 58 is secured to the underside of the bracket by means of fasteners 60. The spring terminates in a pair of downwardly extending portions 62 which are provided with openings 64, these openings serving as journals for a shaft A guide wheel 63 is secured to the shaft and is provi-:led with a recess 70 for engagement with the ridge 45.
The scoring mechanism of this invention is ideally suited for use in conjunction with the folding machine above described. In the embodiment shown, a pair of rings 42 are associated with the upper' roller 28 of the folding unit. The bar 52 is provided in the construction to extend across the machine in parallel with the roller 28. The guide means 50 is thus positioned above the roller 28 in such a manner that a pair or" wheels 63 can be brought into engagement with rings 42 and resiliently pressed `against the rings due to the action of the spring S8.
It will be apparent that during operation of the folding machine paper passing between the exit rollers 26 and 28 can be scored by one or more rings which are positioned in the path of the paper as is the ring 42 shown in dotted lines in FGURE 1. t will be apparent that the scoring results can be accomplished concurrently with the folding operation and without interrupting in any way the progress of the paper. Furthermore, the necessity for an independent scoring mechanism is eliminated, and it will be apparent that the ring and guide means described can be easily incorporated into existing folding units.
The ring and cooperating guide means of this invention are of a particularly unique construction, since they are readily adjustable with respect to the roller with which they are associated. In the embodiment illustrated, the rings 42 can assume any position on the roller 2S by operation of the guide means S0. Specifically, when the set screw 56 is loosened with respect to the bar 52 the set screw will serve as a. handle for moving the guide means and associated ring. This invention provides for movement of the ring and guide means in a simple and etiicient manner if the positioning is carried out while the rollers 26 and 28 are in operation. The movement of the ring results due to the slight difference between the inner diameter of the ring 42 and the outer diameter of the roller 28. With this dimensional difference, lateral pressure applied to the handle 56 will slightly cant the ring 42 with respect to the roller 28 and the `action of the roller will actually drive the ring laterally until the pressure is released. Only a slight amount of finger tip pressure is necessary, and the movement of the ring to any position can be easily and quickly accomplished. When the ring or rings are positioned as desired, the set screw making up the handle 56 is tightened to prevent riding of the ring out of position or accidental movement thereof.
The particular design of the ring 42 is important in order that the desired score mark will be produced without damage to the paper and in order to avoid marking or the paper by a portion of the ring other than the ridge 46. For this reason the ridge 46 is provided with a rounded top whereby a sharp edge will not be presented to the paper. In addition, the outer surface of the ring is tapered toward the side edges whereby contact of the paper with the ring beyond the ridge will not damage the paper. In the embodiment shown, the portion of the outer ring surface which is tapered includes the areas on either side of the ridge beginning midway between the ridge and the edges of the ring. Withthis design the ring will leave only the desired score mark without the presence ot undesirable marks.
A specic example of a suitable ring is a ring with an inner diameter between 1.529 and 1.533 inches. Such a ring, when used in conjunction with 1a roller having an outer diameter between 1.490 and 1.497 inches, has been found to be practical. Other dimensions of the ring include a width of 0.5 inch with a taper of 6 extending from the midpoint on either side of the upstanding ridge to the edges of the ring. The ring has a thickness of 4 0.050 inch wat the ridge point, the ridge itself being 0.020 inch high.
It will be apparent that the dimensions given are provided only for purposes of illustration and that changes in the various dimensions will be necessary for different size rollers, etc. The various size relationships given will provide smooth operation, but obviously other operable relationships are possible.
The character of the scoring ring and guide means described provides many distinct advantages. These means are simple and can be readily adapted into existing units. There is no need to replace any mechanisms when scoring is not desired, since the scoring rings can be easily moved out of the path of the paper as shown in FIGURE 2. The use of a separate scoring mechanism and repeated assembly and disassembly of parts is eliminated by means of this invention. Furthermore, in light of the simple character of the described mechanisms, it will be obvious that integration with existing units can be easily accomplished without a major modification of such units.
it will be understood that various modilications may be made in he above described scoring mechanism which provide the characteristics of this invention without departing from the spirit thereof, particularly as defined in the following claims.
