Definitions

  • the invention relates to a device for adjusting the oscillation amplitude of reciprocating guide channels on zigzag folding apparatus for webs of paper or other material.
  • Known folding apparatus for zigzag folding of webs of paper or other materials are normally connected directly to a printing machine, i.e., a printer for the production of forms from webs of indeterminant length. These folding apparatus fold a printed web of paper or other material so that the web can be bent along lines of perforations, disposed crosswise to the direction of travel. In this way a zigzag stack can be formed so that the individual parts of the web between the perforations are superimposed.
  • the perforations which extend crosswise to the direction of travel of the Web are generally applied in such a way that the imprint made on the web during the printing operation is located between two transverse lines of perforations. If imprints of different sizes are made, the transverse lines of perforations are arranged at a different prescribed distance from one another. Consequently, the stack formed at the output of the zigzag folding apparatus likewise presents different external dimensions. It is therefore necessary to correspondingly adapt the zigzag folding apparatus to the particular spacing of the transverse perforation lines or to the particular imprint size.
  • the folding apparatus must therefore be adjustable according to the format desired during a particular operation.
  • Such a prior art adjustable folding apparatus is disclosed in German Pat. No. 1,070,010 commonly owned herewith.
  • a folding apparatus in which a web of paper or the like to be folded is delivered by means of a movable pocket-like hopper, or a plurality of such hoppers, to the actual folding station. Movement of the hopper is effected by means of cams which may be shifted to adapt to different formats to be folded.
  • Such known device suffers from the drawback of permitting only one specific working speed. If such speed is exceeded, the web to be folded may deviate, for example, from its predetermined path, or there may be other undesired occurrences, so that a regular stack cannot effectively be formed.
  • the present invention is therefore addressed to the problem of avoiding the drawbacks of prior art machines known in this field.
  • a device is therefore provided making it possible to adjust the elements used in guiding the paper web with much greater accuracy and sensitivity than was heretofore made possible.
  • the invention solves this problem in that the cams corresponding to the number of reciprocating elements of the guide channel that control such elements and are displaceable with reference to their drive shafts, are disposed at either edge of the web to be folded and are interconnected in a form-locking manner to their drive shafts, in one or more predetermined positions. It is advantageous that the cams that control the various elements of the paper guide channel be provided with noses which extend into corresponding grooves provided on their drive shafts.
  • the cams controlling the various elements of the paper guide channel be joined to one structural member on one side of the web.
  • the surfaces opposing one another in the displacement of the cams with reference to their drive shafts may be corrugated. It is also possible, however, to provide such opposed areas with a roughened surface.
  • the displacement of the cam with reference to the drive shaft may be made adjustable by means of one or more side plates, each controlled by an additional cam.
  • the invention makes it possible to precisely guide the web to be folded, and to render the cams, that move the machine elements in a reciprocating motion and guide the web to be folded, adjustable on both sides of the web to the same desired degree during the particular operation. According to the invention there is the assurance that this eccentricity once set will be sustained exactly during the entire operation of the machine. Thus, high operating speed is made possible for the entire folding apparatus, an'd the printer connected upstream can therefore be run at' high speeds. Because of the present invention, it is'not necessary to run the printer at a reduced outputJ-The folding apparatus can be speeded up, so that the rate of the printer or its output is no longer limited.
  • the present invention offers a simple opportunity for regulation of the cams, i.e., to convert the folding apparatus from one format to another.
  • This regulation requires only a brief adjustment time and thereby involves only short stoppages for changeover of the entire machine from one format to another.
  • This advantage of the invention allows a further increase in output of both printer and folder.
  • FIG. 1 is a side elevational view, partly in section, of a device in a folding apparatus according to the invention, taken along line l] of FIG. 2;
  • FIG. 2 is a sectional view of the device according to the invention taken along line 2-2 of FIG. 1 and rotated
  • FIG. 3 is a view of the adjustment means taken along line 3-3 of FIG. 2;
  • FIG. 4 is an enlarged view at location 4 of FIG. 2.
  • Web 1 is generally shown in phantom lines in FIG. 1, and is bent in the area of one of its transverse perforations, e.g., at points 2, by means of a beater 3, to thereby form a zigzag stack 4.
  • web 1 passes through one or more pocket-like hoppers or guide channel devices 5 or 5'. The motion of these hoppers is produced by drive rods 6, 6' or 7, 7, in turn moved by cams 8, 8 and 9, 9'.
  • hopper 5 and 5' The tilting of hoppers 5 and 5' occurs because hopper 5 is pivoted about a stationary point 10 on the machine frame by means of drive rods 6 and 6', whereas hopper 5' is pivoted about a pin 11 located on hopper 5 by means of drive rods 7.
  • carns 8, 8 and 9, 9 are displaceable in slots 12, 12 and can be fixed in position by bolts 13, 13'.
  • cams 8 and 9 The drive of cams 8 and 9 is effected by means of a shaft l4located in the machine, the shaft having gear teeth thereon.
  • Shaft 14 rotates at an rpm that corresponds to the rpm of the printer.
  • -Gear 15 engages a gear 16 fixed on a shaft 17.
  • Shaft 17 is mounted for rotation on machine frame 18 and has an intermediate strip 19 mounted thereon along with cams 8 and 9 by means of a bolt 13.
  • cams 8 and 9' also is effected by shaft 17, a gear 20 being fixedly mounted thereon and cooperating with a gear 21 mounted on a shaft 22.
  • Shaft 22 is mounted for rotation on machine frame 18 or 18 and has a gear 23 fixedly mounted on its opposite end. Gear 23 cooperates with a gear 24 fixedly mounted on a shaft 25 which is mounted for rotation on machine frame 18'.
  • Shaft 25 is similar to shaft 17 in that it also has an intermediate strip 19 mounted thereon along with cams 8' and 9' by means of a bolt 13'.
  • cams 8, 9 and 8', 9' are the same so that, for the sake of simplicity, only the setting of cams 8 and 9 will be described.
  • shaft 17 has a flange 27 in which a I groove is provided having surfaces 28 and 29 (see FIG.
  • Strip 19 is located in-the groove for sliding movement in a lengthwise direction, and is fixed therein by means of bolts 30 and 31 engaging with flange 27.
  • the side of strip 19 facing toward cam 8 is provided with corrugations 32 extending perpendicular to walls 28, 29 of the groove.
  • a nose 33 (see FIGS. 2 and 4) of cam 8 extends into the groove of flange 27 and has teeth 34 thereon corresponding to teeth 32 of strip 19.
  • bolt 13 Upon loosening of bolt 13 it is possible to move cams 8 and 9 away from shaft 17 in the direction indicated by arrow A in FIG. 1, to such an extent that teeth 32 and 34 will be moved out of engagement. Nose 33 of cam 8 can then be shifted (in the direction indicated by arrow D in FIG. 1) in the groove defined by surfaces 28 and 29 until the desired setting of cam 8 or 9 is reached. Thereafter, bolt 13 is again tightened, whereby teeth 32 and 34 come into engagement in another relative position than before the adjustment. Obviously, the distribution of teeth 32 and 34 can be finer than that illustrated in FIG. 4.
  • cams 8 and 9 or 8' and 9' are not applied with exactly the same pressure against their respective shafts as a consequence of slight irregularities in the tightening bolts 13 and 13'. Any slight irregularity is thus prevented in the setting of cams 8 and 9 which would cause slantwise guidance, for example, of web 1, to yield a stack which would later be unusable.
  • a hollow shaft 35 is provided on which additional earns 36 and 36' are guided so as to be axially displaceable in the direction of arrows A and B.
  • Aside plate 37 is rotatably mounted on cam 36 which, in the end setting to theleft of cam 36 as in FIG. 2, engages a circular recess 38 of a'plate 39 mounted on cam 9.
  • an end switch 40 is actuated which, during engagement of plate 37 in recess 38, stops the main drive of the machine.
  • a handle 41 on shaft 35 permits it and cam 36 to be pivoted. As shown in FIG. 1, movement of handle 41 in the direction of arrow C causes a movement of side plate 37 in the direction of arrow D. Cams 8 and 9 may therefore be shifted with respect to strip 19 after bolt 13 is loosened.
  • cams 9 and 9' which control hopper 5 can be disposed on another side of the machine with respect to the entrance of web 1 into the folding apparatus as compared to cams 8 and 8' which control hopper 5'. It is also possible to dispose rods 6 and 7 or 6 and 7 on cams 8 and 9 or 8 and 9' which, during assembly of the folding apparatus, may be interconnected for example by bolts. Cams 8 and 9 or 8' and 9 can, however, as shown in the described embodiment, consist of a single structural part. It is also within the scope of the invention to provide a rough surface rather than teeth 32, 34 for the contacting surfaces of strips 19, 19' and cams 8, 8'. If cams 8, 8 and cams 9, 9' are on different sides with reference to web 1, obviously cams 9 and 9 must also be provided with noses which have ridges or a rough surface and which extend into grooves provided on the shafts which drive them.
  • a folding apparatus with the device of the invention may be utilized without upstream connection of a'printer that prints the forms, e.g., for folding a web of paper or the like, rolling off from a roll.
  • each hopper would be moved by a cam associated with it or by a pair on either side of the edges of the web to be folded.
  • a folding apparatus for printing machines including reciprocating guide channel devices for delivering a web of paper or other material downwardly from a web conveyor device in Zigzag folds, driving means for each guide channel device being provided at opposite side edges of the web, said driving means including rotatable cams supporting each said guide channel device for reciprocating same upon rotation of the cams, each cam being mounted on a drive shaft, gear means operatively interconnecting the drive shafts to effect synchronous rotation of the cams; drive means in operative engagement with at least one of said drive shafts; means connected with said guide channel devices for quickly and positively adjusting the oscillation amplitude thereof, each of said cams having an elongated opening extending therethrough, fastening means extending through said openings for mounting said cams to their respective drive shafts, a surface of each said cam adjoining a surface of its respective shaft when mounted thereto, the adjoining surfaces between said respective cams and said drive shafts being roughened, said surface of each of said drive shafts being provided with a groove extending parallel to said e
  • each said guide channel devices comprise at least two guide channels, and each said cam comprising at least two cam elements integrally connected together, each said channel of each said guide channel device being independently connected to a respective one of said cam elements.
  • said adjustment means includes rotatable cam members and side plates mounted thereon said plates being engaged with each said cam, respectively, said cam members being operatively interconnected by means of a movable shaft for sliding movement therealong and for rotational movement together therewith to effect synchronous adjustment of said cams with respect to their drive shafts.
