Definitions

  • the invention relates to a folding and stapling machine for paper sheets with a folding device which folds the paper sheets in a folding position along a fold line, and with a stapling device which staples the sheets in the region of the fold.
  • Such machines are used, for example, to produce smaller brochures.
  • the sheets of paper which are superimposed flat and which are to be connected to one another are brought to a stapling position in which the stapling device connects the sheets to one another, and the sheets which have been stapled to one another are then brought into a folding position by a sliding movement lying in the plane of the paper, in which a folding sword, which is moved transversely to the plane of the paper, comes into contact with the paper on the folding line and moves the paper between pressure members which fold the paper around the folding sword.
  • it is difficult, particularly in the case of changing formats of the processed paper sheets to carry out the stitching exactly on the fold line, which is desirable per se.
  • the object of the invention is to avoid this disadvantage.
  • This object is achieved according to the invention in that at least one movable part of the stapling device is guided such that it engages the paper in the folding position or on the paper during or immediately after the folding process.
  • the advantage of the invention is that because between the stapling process and the folding process there is no sliding movement running in the plane of the paper, the stapling is always carried out exactly at the location of the folding line, without special adjustment measures being required.
  • the folding device is assumed below that it is such a folding device which is known in principle for stapling paper and in which a stapling head which is connected to a magazine for staples or in which the staples are bent out of wire are movable relative to a die, the die having guides for the ends of the staples that bend the free ends of the staples.
  • stapling devices are not excluded, in which the entire stapling device is only on one side of the stapling paper and in which, for example during the stapling process, the parts causing the ends of the staple to bend through the paper.
  • Devices of this type are known, for example, for closing cardboard boxes.
  • the above-mentioned movable part of the stapling device is therefore generally the stapling head or the die of the stapling device, that is to say a part which is required directly for the stapling process.
  • At least part of the stapling device is arranged in the path of a folding sword during the stapling process, which describes this path during folding.
  • the folding sword comes to rest on a part of the stapling device during or after the end of its movement causing the folding.
  • the part of the stapling device mentioned is a stapling head. In this embodiment, stapling is only after the beginning of the folding process.
  • the described embodiment of the invention includes the possibility that the folding sword comes into contact with the mentioned part of the stapling device while it is being folded, said part of the stapling device then covering a distance together with the in embodiments of the invention Can move the folding sword, and the possibility that the folding sword only comes to rest on the mentioned part of the stapling device at the end of its movement.
  • a die for bending the staples is arranged in the folding sword. It goes without saying that, depending on the number of staples to be attached, a corresponding number of dies must be provided. These matrices need only have a small width so that the folding sword can be relatively thin, although it contains part of the stapling device, namely the die.
  • a stapling head of the stapling device is guided such that it can be moved against the paper in the folding position.
  • the stapling process can therefore take place before the folding process has started and without any folding sword that may be present moving in the direction causing the folding.
  • embodiments are not excluded in which the folding process only takes place during a movement of the folding blade in the direction causing the folding.
  • the stitching head has an elongated staple channel, the free end of which is moved for stitching between the pressure members of the folding device.
  • the staple channel is only just long enough that it just holds the staples, for example fed from a magazine.
  • the extended clamp channel which only has to have a relatively small thickness, can be moved without difficulty, for example, between clamping rollers provided for folding, which are expediently spring-loaded. This has the advantage that the pinch rollers act on the entire length of the paper and can thereby fold it evenly.
  • the invention does not exclude embodiments in which the pressure members, for example pinch rollers, do not extend over the entire length of the fold line, but leave gaps through which a relatively thick stitching head can also be moved without the pressure rollers moving sideways have to.
  • the stitching head and the folding sword are firmly connected to one another, and both are guided in a direction essentially transverse to the plane of the paper to be folded and can be driven in a reciprocating movement. If the stapling head is moved against the paper to be folded, the stapling process is carried out, the folding sword being at a distance below the paper to be stapled; if the stitching head is moved in the opposite direction, the folding sword approaches the side of the paper facing away from the stitching head and moves it between the pressing members of the folding device. The length of the stroke which the stitching head and the folding sword perform must be greater than the distance between the stitching head and the folding sword.
  • the machine in FIG. 1 like all the other machines shown, has a table surface 1 which runs obliquely with respect to the horizontal, in the lower region of which a stop 2 is arranged, which can be adjustable and on which an electrical switch contact 3 is arranged.
  • the sheet of paper to be stapled and folded can be placed on the table surface 1 in the left area of FIG. 1 by hand or by a suitable device and then slide into the correct position for folding, in which it is held by the stop 2.
  • Below the table surface 1 there is a folding sword 5 which is linearly displaceable at right angles to the table plane and is guided in the indicated guides 6 and 7 and by a schematically indicated drive motor 8 which is provided with a gear; can be moved obliquely up and down via a gear 9.
  • a control device 10 is connected to the switch contact 3 and to an electrical, manually operated push-button switch 12, and in a manner not shown to the motor 8 and the other electric drives not yet mentioned.
  • the controller 10 effects the correct sequence of the individual movement processes and can either be triggered by the stapling the and to be folded paper layers on the switch contact 3 come to rest, or the work process is triggered by actuating the switch 12.
  • rollers 16 and 17 are rotatably mounted in a housing 15 with parallel axes of rotation, both of which are driven to rotate in the direction of rotation shown; 2 shows an electric drive motor 19 for the roller 16.
  • the roller 16 is also guided by means of a sliding guide 21, 22 on the wall 23 of the housing 15 in a direction parallel to the table surface 1, namely in the direction of the steepest slope, that is, in the drawing plane of FIG. 1, and by an electromagnet 25, which is fastened to the housing 15 by means of a holder 26, can be displaced from the position shown in FIG. 1, away from the roller 17, into a position closer to the roller 17.
  • two stapling heads 30 are fastened to a carrier 28 fastened to the housing 15, each of which has a magazine 31 for conventional staples (see FIG. 11) and a driver 33 designed as a sheet corresponding approximately to the thickness of the individual staples which, when it is moved obliquely downward to the left relative to the remaining stapling head 30, pushes a staple out of the magazine downwards.
  • the drivers 33 are fixed immovably on the carrier 28, a main part 35 of the stitching head 30 is connected to the carrier 28 via a compression spring 36, so that the stitching head 30 normally assumes its lowest position shown in FIG. 1. If the stapling head 30 is moved upward against the force of the compression spring 36, a staple is ejected because the Driver 33 is immobile.
  • the folding blade 5 contains two matrices 38 at a distance corresponding to the distance between the stitching heads 30. If the stop 2 is set so that when several sheets of paper lie against it, the folding line is located exactly above the free end of the folding blade 5, then When the folding blade 5 is moved upwards, the paper 40 is drawn between the rollers 16 and 17 in the manner indicated by the dot-dash line and is thereby folded. The folding sword 5 is moved upwards so far that it pushes the stapling head 30 against the force of the spring 36 so far that a staple penetrates the paper on the folding sword and is bent by the die 38 in a manner known per se.
  • the arrangement is such that after the completion of the stitching process, the folding blade 5 is moved down again into the position shown in FIG. 1, that the roller 16 is then moved to the roller 5, whereby the stapled and folded brochure is now through the rollers 16 and 17 is driven in an upward direction.
  • a deflection plate 42 which is pivotally mounted about a horizontal axis 43, the brochure is guided between two rollers 46 and 47, which are arranged at a relatively short distance from one another and are also driven in opposite directions by means of a motor 45, which further reinforce the fold and the brochure out of the machine eject, in the example the brochure 44 is placed on a conveyor belt 41 which is only indicated.
  • a guide plate 49 opposite the deflection plate 42 ensures that the brochure is securely in the Gap between the rollers 46 and 47 arrives.
  • the deflection plate 42 has recesses 48 in its lower region adjacent to the rollers 16 and 17, which are arranged as shown in FIG. 2 that during the stitching process in which the folding blade 5 moves upward, the baffle 42 can also be pivoted upward, so that it does not collide with the stitching heads 30 and does not hinder the stitching process thanks to its recesses 48.
  • the machine shown is a normal so-called block stitching machine, i.e. to staple without folding.
  • the paper is placed on a table surface 50 which runs parallel to the table surface 1 and ends above the roller 16 and is inserted below the stitching head 30 in this plane determined by this table surface 50.
  • the baffle 42 is swung up beforehand and locked in the swung-up position so that it is not in the path of the paper being inserted. There is no ejection via the rollers 46, 47.
  • the machine 53 again has the sloping table surface 1 with the stop 2.
  • the folding blade 55 is located below the table surface 1 and the stitching head 56 is located above it.

  • This machine also has two stitching heads 56 which are arranged one behind the other at a distance from one another and in the viewing direction of FIG. 3.
  • the stitching heads are connected to one another by a carrier 54 which is longer than the largest width of the paper to be processed measured perpendicular to the plane of the drawing in FIG. 3.

  • FIGS. 3 to 6 works as follows: In the position shown in FIG. 3, in which the folding sword 55 is located completely below the table surface 1 and the stitching head 56 is at a distance above the table surface 1 and even more above the rollers 63 and 64, the paper 40 can be slid into the machine from above on the table surface 1 and comes to rest at stop 2. The motor 8 then moves the rods 60 and thus the folding blade 55 and the stitching heads 56 downward until the end of the staple channel 57 presses the paper against the die 66.
  • the driver 58 is moved down by the motor 59 and drives a staple through the paper, thereby causing the stapling; 4 shows that position of the machine in which the stitching head 56 has reached its lowest position and at the same time the driver 58 is also in its lowest position. The paper already stapled is still completely flat at the time shown in FIG. 4.
  • the motor 8 simultaneously moves the stitching head and the folding blade upwards, to the extent that the folding blade projects upwards above the table surface 1 through a recess in the table surface 1 and thus brings the paper 40 between the rollers 63 and 64.

At this moment the driver 58 has reached its lowest position. Then the driver 58 is raised again and takes the stitching head 56 and the guide frame 107 with it as soon as the cross bar 5 comes to rest on the upper end of the slot 106. The guide frame 107 moves further upward, the folding sword 55 penetrates the plane of the table surface 1 and brings the stapled paper 40 between the two rollers 163 and 164, which are now again closely adjacent to one another and elastically by the tension spring 116 be pressed against each other. The paper 40 is thus folded between the rollers 163 and 164 and then deflected by a baffle 142 and thrown out of the machine.

  • FIG. 14 shows a further embodiment of the invention, in which, in contrast to the embodiments described above, no rollers are used for folding.
  • These Embodiment is particularly advantageous when folding relatively thick layers of paper, because when folding by means of rollers, the sharpness of the fold generally becomes worse the thicker the layer of paper to be folded. This is because the contact pressure of the rolls used for folding must not be too great, because otherwise the rolls can no longer grip the paper to be folded securely.

  • roller 226 actuates an angle lever 280, which in turn is supported on the cam disk 224 via a roller 281 and whose longer lever arm 282 acts on the free end of a push rod 283 which is mounted in the machine 201 so as to be displaceable in a horizontal direction and from which one Arm 284 protrudes downward, which carries the solenoid 278 and thus the ejector fingers 280.
  • a toothed rack 286 which engages with a toothed wheel 287 which is rotatably mounted about a fixed axis and which in turn is in engagement with a toothed rack 288 which engages on its underside, which is horizontally displaceably mounted and on the latter a downward arm 289 is arranged on the right end and carries ejector fingers 290 at its lower end.
  • the racks 286 and 288 therefore inevitably always move in the opposite direction because of the engagement in the gear 287. If the push rod 263 is moved to the right in the manner described, the ejector fingers 280 consequently move to the right in FIG.
  • the stapled and folded paper layer reaches a support surface 293 via a chute 292.
  • the pre-folded brochures can be removed from there or transported from there using a conveyor belt.
  • any other suitable measure or device can be used to produce a downward bulge in the paper web 202 in the region between the pairs of clamping jaws will; for example, the downward bulge can be generated by compressed air acting on the upper side of the paper web 202 or by a rod pressing downward acting on the upper side.
  • the ejector fingers 280 need only be raised per se when a new paper web 202 is inserted into the machine 201. In the exemplary embodiment, however, the ejector fingers 280 are lifted a short time after the push rod 283 has assumed its position that has been shifted furthest to the right.
