Definitions

  • the invention relates to a folding machine for folding large-format cardboard blanks consisting of heavy corrugated or solid cardboard according to the preamble of claim 1.
  • the adjustment to cardboard blanks of different lengths or depths is made by adjusting the stops against which the inserted blank strikes with the leading edge of the side parts to be folded.
  • the folding rail is only tightened a considerable distance behind the leading edge of the blank in the case of cardboard blanks that are less long.
  • the band-shaped folding rail must also be made stronger and therefore relatively thick in the direction of its smallest moment of inertia. Otherwise, the blank to be folded would only be clamped on the trailing edge, that is to say on the inlet-side end of the folding rail.
  • a thick folding rail must be moved further inwards than a thin folding rail so that it does not hinder the folding in of the side parts of the blank in the fold.
  • the thickness of the folding rail is not increased, it may not be possible to ensure that the blank is held firmly in place if the side parts of the blank come free from the stops when folded in and can no longer be guided there. In this case, the blank can then slip slightly under the folding rails, which is just as detrimental to the precision of the folding as a recessed folding rail.
  • a good hold on the blank is also absolutely necessary for the effectiveness of the postforming devices that are intended to postform the folded edge, because otherwise the folded blank will slip when the postforming device is put on and therefore only an incomplete result will be achieved.
  • the object of the invention is to develop the known folding machine in such a way that blanks of different lengths can also be folded with greater accuracy.
  • the folding rail can be clamped just in front of the leading edge of the blank, so that even with relatively very thin folding rails a perfect clamping of the blank is achieved on the leading and also on the trailing edge.
  • the thin folding rail can be moved closer to the edge to be folded, which enables two effects to be achieved, which support each other in terms of improving the precision of folding:
  • the perfect clamping of the blank effectively prevents the blank from slipping even when the partially folded side parts have already been released from their stops, while the folding rails which have been pushed out as far as possible can serve as a ruler for the formation of the fold when folded.
  • a further reduction in the necessary contact pressure can be achieved with flat contact surfaces, because this creates large contact surfaces with the folding rails, which lead to high static friction with low force. It is particularly advantageous here if the contact surfaces are mounted and guided in the fixing devices in such a way that the contact surfaces run substantially parallel to the associated folding rail, at least when it is in contact with the rear side thereof. It is even more favorable if the contact surfaces lie parallel to the back of the folding rail over their entire stroke, since then even with different thicknesses of material there is a tight contact of the contact surfaces on the rear sides of the folding rails.
  • a storage of the contact surfaces which meets the above conditions, and at the same time is able to absorb considerable lateral forces with a simple structure, is to provide each contact surface on a holder on which two parallelogram links are articulated on one end, the other ends in the Fixing device are pivotally mounted, such; that the contact surfaces can be moved towards or away from the back of the folding rails essentially vertically.
  • This type of storage also has the advantage of being low and therefore does not have to protrude too far beyond the back of the folding rail.
  • the one parallelogram link is designed as a two-armed lever, one arm of which leads to the holder and the other arm of which protrudes beyond the bearing point in the fixing device, the pressure medium cylinder can be coupled to the protruding end and can be attached next to or below it.
  • a cheap material for the contact surface, which on the one hand creates sufficient friction and on the other hand does not damage the back of the folding rail, is made of polyamide.
  • Adjusting the folding machine to different cut sizes is made easier if the on Impacts are arranged directly on the fixing devices, because this means that the manufacturer's favorable offset between the contact surface and the adjacent stop is always maintained without additional settings.
  • the associated contact surfaces for the folding rail are set back so far relative to the stop seated on the fixing device that the edge of the contact surface adjacent to the inserted blank is opposite the stop or the adjacent edge of the introduced blank jumps back.
  • the amount by which the corresponding edge of the contact surface springs back is advantageously between 0.5 and 5 cm.
  • FIG. 1 shows a section of a folding machine 1 with its folding station or folding device 2.
  • the illustration is made in such a way that only the part of the folding station 2 or the folding machine 1 is illustrated which produces the folding edge of the corresponding inserted cardboard blank facing the viewer, while the other part of the folding station 2, which the Folded edge facing away from viewer is omitted; this part is a mirror image of the part shown in FIGS. 1, 4, 5 and 6.
  • the folding station 2 contains two parallel supports 4 and 5 (see FIG. 2), which are arranged in a machine frame 3 and can be adjusted towards each other according to the width of the blank, the upper sides of which lie in a common plane.
  • the folding rails 6 and 7 are attached to associated actuating devices in the form of double-acting pressure medium cylinders.
  • the front end of the folding rail 6 is coupled to the pressure medium cylinder 8 arranged in the machine frame 3, the working direction of which is perpendicular to the plane spanned by the supports 4 and 5.
  • fixation devices are used, of which the fixation device 9 is visible in FIG. 1 and in a view opposite the direction of travel in FIG. 3 the cut is shown on an enlarged scale.
  • the fixing device for the other folding rail 7 is constructed in mirror image.
  • the fixing device 9 has a housing 11 which is approximately H-shaped in cross section and has two vertically extending legs 12 and 13 which are connected to one another by a crossbeam 14. In relation to the center of the machine, the fixing devices 9 can be seen to extend outwards from the folding rails 6, 7 and can be extended along the supports 4, 5.
  • a pressure member 15 is mounted in the housing part 12 so that it can be moved up and down by means of parallelogram links 16 and 17.
  • the parallelogram links 16 and 17 are pivotally connected to a support 21 at articulation points 18 and 19 and to the housing part 12 at articulation points 22 and 23.
  • the articulation points 22 and 23 are arranged one above the other along a vertical line and their axes run parallel to one another or parallel to the longitudinal extent of the folding rails 6 and 7. Since the parallelogram links 16 and 17 have the same length and also the distance between the articulation points 18 and 19 is equal to the distance of the articulation points 22 and 23, the pressure member 15 performs a purely translational movement when the parallelogram links 16 and 17 are pivoted.
  • a polyamide block 24 is fastened, the flat underside 25 of which forms a contact surface which, due to the parallelogram link arrangement, always runs parallel to the back of the folding rail 6 or the folding rail 7 and, when pressed on, can lie snugly against said back.
  • a double-acting pressure medium cylinder 26 is provided in the housing part 12, the piston rod 27 of which is articulated to an extension 28 of the parallelogram link 16, which projects beyond the articulation point 22.
  • the pressure medium cylinder 26 is seated in an abutment 28 within the housing part 12, which extends essentially vertically next to the associated folding rail 6 or 7.
  • a longitudinal guide 31 consisting of two rotatably mounted rollers 32 and 33, is provided.
  • the longitudinal guide 31 engages around a frame-fixed guide rail 34, so that the rollers 32 and 33 are on the upper and un tere narrow sides of the guide rail with a rectangular cross section can roll off.
  • the guide rail 34 itself is fixed to the frame outside the corresponding adjacent support 4 or 5 running parallel to this.
  • a roller guide 35 is also provided at the lower end of the housing part 13, which also runs along corresponding rails, not shown. These rails for the guide device 35 run parallel to the rails 34 on the outside of the machine.
  • one of the support rails, the support rail 36 can be designed as a rack, in which a pinion 37 engages, which by means of a handwheel 38 mounted in the housing part 13 and corresponding gear devices, not shown in detail, in Is to be rotated in order to move the entire fixing device 9, possibly also with the pressing surfaces 25 pressed onto the folding rails 6 and 7, along the folding rails 6 and 7 or the supports 4 and 5.
  • the fixing device 9 can be fixed in the appropriate position by means of clamping devices, not shown in detail.
  • a stop 39 is attached on the side of the housing which is adjacent to it when the blank is inserted.
  • the stop 39 forms a flat stop surface which lies in a plane which is penetrated vertically by the supports 4 and 5 or the folding rails 6 and 7.
  • the stop 39 is advanced by a certain amount in relation to the contact surface 25, or conversely the contact surface 25 jumps in relation to the stop surface of the stop 39 by a certain amount between 0.5 and approximately 5 cm back so that when the blank is inserted, the pressure member together with the pressure surface 25 is out of the swivel range of the side part of the blank to be folded.
  • the stops 39 of the two fixing devices 9 extend, starting from a region in the vicinity of the associated folding rail 6, 7 or support 4, 5, towards the outside of the machine, i.e. away from the folding rail, the distance between the stop surface of the stop 39 and the corresponding folding rail 6, 7 being so large that when the side part is folded in, the blank is free of the corresponding stop 39 and is readily on the inside of the pressing member 15 when it is raised Housing part 12 can pull down from the folding rails 6 and 7.
  • a total of four folding arms or folding levers are provided in the folding station 2 for the edges to be folded, of which only the two folding levers 41 and 42 are illustrated in FIG. 2, which one of the folding edges facing the viewer are assigned to be cut.
  • the two folding arms 41 and 42 sit on a shaft 43 which is rotatably mounted in the machine frame 3 and which extends parallel to the associated adjacent support 4 next to its side facing the outside of the machine. In their initial or resting state, the two folding arms 41 and 42, which are arranged on the shaft 43 so as to be displaceable and clampable, point outwards and are located below the level defined by the supports 4 and 5, thereby removing one from the transport path to be fed are cut out.
  • the fixing device 9 contains corresponding openings on its side of the housing part 12 facing the inside of the machine, so that the fixing device 9 can be pushed unhindered by the shaft 43 in the direction of the front end of the folding rail 6 or 7.
  • a post-forming device 44 which has a shaft 45 which runs parallel to the shaft 43 and is rotatably mounted in the machine frame 3 between the shaft 43 and the support 4 (FIG. 14). contains. Attached to the shaft 45 is a bar or flap 46 which can be pivoted through it and extends practically over the entire length of the folding station 2.
  • the strip 46 In the initial or idle state, the strip 46 is located outside the transport path of a blank to be fed and is folded approximately vertically upward after folding, as described below, as shown in FIGS. 5 and 14. So that the flap 46 cannot rub against the housing part 12 of the fixing device 9 or is even blocked by it, the clearance profile of the side of the housing part 12 facing the inside of the machine is contoured accordingly.
  • the part of the folding station 2 which is not illustrated is designed as a mirror image of the part shown in FIG. 1 and also contains corresponding components.
  • the folding station 2 is first set to the width of the completely folded blank 47 shown in FIG. 14, in such a way that when the post-forming device 44 is folded up, the distance between the two strips 46 is exactly the desired distance between the two running fold edges 48 and 49 of the folded blank 47 corresponds. Because of the spatial assignment and the corresponding mechanical connection with one another, the supports 4 and 5 are accordingly closer to one another, so that they are closer to one another than the folded edges 48 and 49 and are within the limit defined thereby. The folding rails 6 and 7 have migrated accordingly with the supports 4 and 5 and are largely above this.
  • folding rails 6 and 7 serve at the same time as a ruler for the actual folding, it is expedient if they come as close as possible to the inside edge of the folding edges 48 and 49 within the angular space created after the folding.
  • the shaft 43 for the folding arms 41 and 42 is also laterally shifted accordingly.
  • a creasing device formed by rollers 51 a and 51 places the blank 47 in the correct place, namely along fold lines 52 and 53, grooves, which in turn are aligned with corresponding incisions 54 and 55.
  • the correct lateral position of the blank 47 is ensured by a correspondingly set side stop 56 which is attached in front of the folding station 2.
  • upper transport rollers 57 are raised by a pressure medium cylinder 58 coupled to it.
  • Auxiliary stops 59 are raised and are in the path of movement of the blank 47 presented.
  • Spring-loaded transport pawls 61 of an auxiliary transport device 62 are erected and brought into the foremost position by associated drive devices.
  • the two folding rails 6 and 7 are raised from the associated supports 4 and 5 with the aid of the associated pressing devices, namely the pressure medium cylinder 8.
  • the pressure surface 25 is also raised and is at a distance from the corresponding folding rail 6 or 7, which, as shown in FIG. 7 in a somewhat exaggerated representation, starting from the pressure medium cylinder 8 until it rests on the associated support 4 or 5 hangs down.
  • pivoting flaps attached to the stops 59 trigger the electrical control of the folding machine via associated switches, as a result of which, as shown in FIG Pressure medium cylinder 58, the upper transport rollers 57 are lowered.
  • the drive device, not shown, for the stops 59 pulls them downward out of the path of movement of the blank 47, whereupon the drive device, also not shown, for lower transport rollers 64, against which the blank 47 is pressed by the upper transport rollers 57, then starts.
  • the blank 47 lies over the front transport rollers 64 of the transport device when it is placed against the stops 59, so that when the drive is switched on in the direction of an arrow 65 into the folding station 2 is drawn in.
  • the leading or leading edge of the blank 47 forwards the spring-loaded pivotable pawls 61 of the auxiliary transport device 62, which consequently do not hinder the pull-in movement of the blank 47.
  • the blank 47 When the blank 47 is drawn into the folding station 2, the blank is also pre-grooved by means of the creasing devices 51 a and 51 b along the folding lines 52 and 53, which separate the side parts 66 and 67 to be folded in from the center piece 68 lying on the supports 4 and 5.
  • the blank 47 is now pushed through the transport device 57, 64 onto the supports 4 and 5 until the rear edge, i.e. the trailing edge of the blank 47 has come free from the rear transport rollers 64.
  • the trailing edge of the blank 47 has already passed the foldable pawls 61, which, due to the spring prestressing force, can straighten up again into the starting position, in which their upper edge extends into the transport path of the blank 47. As soon as this position shown in FIG.
  • the drive devices are started in the form of a corresponding pressure medium cylinder 69, which then prefers the pawls 61 in the direction of the supports 4 and 5.
  • the pawls 61 come into engagement with the trailing edge of the blank 47, which is thus advanced by the pawls 61 until the front edge of the blank 47 abuts the stops 39 of the fixing devices 9. This position is illustrated in Fig. 11.
  • the pressure medium cylinders 26 are set in motion, which, via the lever and parallelogram gears 16, 17, 28, move the pressure members 15 downward in the direction of the associated folding rail 6 or 7, until the contact surfaces 25 on the rear side of the folding rails 6, 7 lie on it and press it down with a predetermined force.
  • the pressing surface 25 engages the folding rail 6 or 7 just next to the front edge of the blank 47 and presses it down in the immediate vicinity. Even if the folding rail 6 or 7 consists of very thin elastic band steel, this small distance between the contact surface 25 and the edge of the blank 47 produces a sufficient contact force to clamp this leading edge at this point on the supports 4 and 5, respectively.
  • FIG. 12 After the operating position shown in FIG. 12 has been reached, which is also illustrated in a perspective view in FIG. 4, the folding arms 41 and 42 are pivoted via the shaft 43 from their rest position in FIG. 2 towards the inside of the folding machine 1 and fold the corresponding side part 66 or 67 projecting outwards beyond the respective folding rail 6, 7, ie the side parts are turned over by not quite 180 ° almost immediately around the outer edge of the folding rail 6 or 7.
  • the blank 47 will ver on the supports 4 and 5 during the further folding of the side parts 66 and 67.
  • the pressure medium cylinders 8 and 26 are actuated in the sense of lifting the folding rails 6, 7, i.e. the folding rails 6, 7 are raised at their front end, while at their rear end, which is located in front of the front edge of the finished folded blank 47, they rest loosely only on account of their own weight on the associated support 4 or 5.
  • the finished folded blank can now be transported out of the folding station 2 according to FIG. 13 by means of a conveyor chain 71 and a stop 72 attached to it and into a subsequent stapling or gluing station which is not further described.
  • the free rear ends of the folding rails 6 and 7 slide out of the resulting flat box hose or the box hose is pulled down from the folding rails 6, 7 under the lifted contact surfaces, whereby it remains lying on the supports 4 and 5.
  • stops 39 only engage in the area of the side parts 66 and 67 to be folded over on the front edge of the blank 47 which is still lying flat, after the blank 47 has been folded, its pushing out of the folding station 2 is not impeded by the stops 39 and the box tube is between the fixing devices 9 pulled out.
