Definitions

  • the invention relates to a method for at least partially unpacking a paper roll according to the preamble of claim 1 and an apparatus for performing the method.
  • Paper used for printing, in particular, newspapers is supplied to the printer in the form of paper rolls wound on a central sleeve made of solid cardboard, the weight of which can be several tons.
  • the rolls are protected by packaging made of strong wrapping paper, which is usually supplemented by cardboard side plates on the front sides.
  • sleeve cores are inserted under the side plates to protect the sleeve in the ends.
  • the invention has for its object to solve these difficulties and to provide a method with which a fully automatic unpacking of paper rolls is possible regardless of the dimensions of the same and the type of packaging and an apparatus for performing the method.
  • the invention provides a method in which the difficulties described above are avoided by unpacking the roll by opening the packaging at the center of the end face is where it can be pierced without any danger to the paper roll, because a corresponding tool either hits a core of the sleeve, which is then gripped and removed or pushes into the hollow sleeve.
  • the packaging is torn open by the same or by the core of the sleeve, so that a free area is created on which a cutting tool can be attached. From this starting point, the packaging can then be removed without major difficulties.
  • the dimensions of the roll - length and diameter - are automatically taken into account in the method according to the invention.
  • the unpacking device comprises a frame 1 fastened to the floor, on which a portal 2 is movably mounted.
  • a lifting platform 3 for a paper roll 4 is recessed in the floor with two support rollers 5a, b, which are aligned parallel to the portal 2 and are arranged next to one another at a distance. which can be raised and lowered and at least one of which can be driven.
  • the lifting platform 3 is connected to an automatic underfloor transport device, as has been known for a long time for the paper roll transport.
  • the paper roll 4 lies on the support rolls 5a, b, its axis is aligned parallel to the portal 2, its direction is referred to below as the longitudinal direction.
  • the portal 2 comprises two side beams 6a, b, with support arms 7a, b projecting against the lifting platform 3, which are connected by a longitudinal beam 8 designed as a double-T beam.
  • a longitudinal beam 8 designed as a double-T beam.
  • two slides 10a, b which can be advanced and retracted against the center of the portal by means of belt drives 9a, b, are mounted, each comprising a vertical beam 11, along which a crossbeam 12, which carries a first button 13 designed as a roller, by means of a compressed air piston 14 is movable.
  • a horizontal arm 15 which is connected to the crossbar 12 via a vertical spindle 16, so that the arm 15 is moved with the beam 12, but the vertical distance between them can be changed by means of the spindle 16.
  • the arm 15 also carries a tear-open device 17 directly below the first button 13, the structure and function of which are explained below (FIGS. 7a-d, 8a, b, 9) and at the opposite end a second button 18, which is designed as a guide roller and is displaceable to a limited extent along the arm 15 and is acted upon by a spring with a force directed against the carrier 11.
  • the arm 15 also carries a side knife 19 (FIGS. 7a-d, 10a, b) which can be displaced along the same by means of a drivable belt 20 (FIGS. 3, 6).
  • a photocell 21 is attached in the longitudinal direction next to the first button 13, which by upstream aperture has a pronounced directional characteristic, so that it only responds to the incidence of light obliquely from below, from a direction that includes a scanning angle of 45 ° with the vertical. It acts with a light source 22, z. B. an infrared light emitting diode together, which emits an obliquely upward directed beam of light, the direction of which includes the scanning angle of 45 ° with the vertical.
  • the slides 10a, b are also equipped with feeler rollers (not shown) which are rotatable about axes directed transversely to the longitudinal direction and are advanced somewhat towards the center of the portal.
  • a jacket cutting device 23 is attached to the longitudinal beam 8 and can be displaced in the longitudinal direction by means of a belt drive. It comprises a sheath knife 24, the construction of which is explained in more detail below (FIG. 11) and a compressed air piston 25, by means of which the position of the sheath knife 24 can be adjusted transversely to the longitudinal direction.
  • the longitudinal member 8 also carries an adhesive device 26, which need not be discussed in more detail here.
  • a plurality of drivable belts 27 arranged next to one another are installed for removing the paper roll packaging, to which drivable belts 28 are connected, which are directed obliquely upwards in two groups, which form a narrow slot 29 between them. They lead to a winding device 30, which is described in detail in EP-A-0 557 725.
  • the ripping device 17 fastened to the arm 15 (FIGS. 7a, 9) comprises a mandrel 31 which is fastened to a holder 32 which can be moved in the longitudinal direction by means of a compressed air piston 33, so that the mandrel 31 can be advanced and retracted towards the center of the portal.
  • the mandrel 31 consists of a sleeve 34 which is closed at the end by a bolt 35 with a conical tip and a locking rod 36 which is displaceably mounted in the interior thereof and which can be slightly advanced and retracted in the sleeve 34 by means of a compressed air piston 37.
  • the locking rod 36 carries (FIG.
  • the mandrel 31 is surrounded by a sleeve 41 which is acted upon by a spiral spring 42 supported on the arm 15 with a force acting in the retraction direction.
  • the cuff 41 has an indentation in the area of its front end, with which the latches 38a, b can engage. On the outside, the front end area is provided with a plurality of protruding rings arranged in short succession in the longitudinal direction.
  • the side knife 19 (Fig. 10a, b) consists of a radial knife 43 designed as a plow knife with a base plate 44 and a radial wedge 45, to which a radial cutting disk 46 is rotatably fastened, and a circumferential knife 47 oriented perpendicular thereto with a peripheral wedge 48 and a peripheral cutting disk 49, which is rotatably attached to the base plate 44 and protrudes into the angle formed between the same and the peripheral wedge 48.
  • the sheath knife 24 (FIG. 11) is fastened to a holder 50 which is suspended in a spring-loaded manner by means of a parallelogram suspension 51. It is designed as a plate which ends in a tip 52, the upper edge of which forms a cutting edge 53.
  • a positioning roller 54 is attached to the holder 50 somewhat in front of the tip 52, the axis of which is mounted eccentrically, i. H. in turn can be rotated about a slightly offset positioning axis, so that the height of the positioning roller 54 relative to the sheath knife 24 can be changed by rotating the roller axis about the positioning axis.
  • a brush 55 is rotatably suspended in such a way that in the basic position shown in FIG. 11 it lies slightly in front of the tip 52, but can be folded out of the area thereof against the force of a tension spring 56.
  • the paper roll 4 is a cylindrical wrap placed on a solid cardboard tube 57 with two end faces 58a, b and a lateral surface 59.
  • core cores 60 which are used as rings such as rings, are usually inserted into the same, but not with each type of roll.
  • B. are made of chipboard material with a central opening 61.
  • the end faces 58a, b of the paper roll 4 are mostly covered by circular side plates 62 made of cardboard.
  • the paper roll 4, possibly including side plates and sleeve cores, is surrounded on all sides by a sleeve 63 made of strong wrapping paper.
  • the packed paper roll 4 is transported to the lifting platform 3 by the underfloor transport device.
  • the support rollers 5a, b are then raised until the Paper roll 4 rests on them and they take them further into the position shown in FIG. 1. Since the support rollers 5a, b lie parallel at the same height, the intersection points of the axis of the paper roller 4 with the end faces 58a, b each lie in a vertical plane which lies centrally between the support rollers 5a, 5b.
  • the portal 2 is moved against the lifting platform 3 (arrow a in FIG. 4) until the first button 13 lies exactly in the said plane.
  • the slides 10a, b are positioned in the end regions of the portal 2 so that they do not collide with the paper roll 4. They are now advanced by means of the belt drives 9a, b against the center of the portal until their sensing rollers (not shown) touch the end faces 58a, b of the paper roll 4, as a result of which the carriages 10a, b are stopped.
  • the crossbar 12 is lowered vertically by the compressed air piston 14 along the support 11 (arrow b in FIG.
  • the arm 15 is lowered from its upper limit position by means of the spindle 16, as a result of which the second button 18 is pressed down and, as a guide roller acted upon by a force acting against the lateral surface 59 of the paper roll 4, rolls along it until the light beam from the light source 22 hits the photocell 21 at a scanning angle of 45 ° to the vertical and causes it to emit an output signal which exceeds a response threshold and an immediate one Aborting the movement of the spindle 16 and thus stopping the arm 15 causes.
  • the first button 13, the second button 18 and the center of the end face 58a or 58b now form an isosceles right-angled triangle, ie the center is at the same height as the second button 18 and directly below the first button 13.
  • This process of determining the centers of the end faces 58a and 58b can be modified in that in the starting position the arm 15 is in the lower limit position and can be raised by the spindle 16 until the photocell 21 responds.
  • the function of the tear-open device 17 differs depending on whether or not the paper roll 4 belongs to a type provided with sleeve cores 60. The first-mentioned case is explained below with reference to FIGS. 7a-d.
  • the mandrel 31 is retracted by the compressed air piston 33 with the latches 38a, b folded in - they are retracted relative to the slots 39a, b to such an extent that they cannot unfold - from the starting position (FIG. 7a) in which it is retracted into the sleeve 41 , advanced, pierces the sleeve 63 and the side plate 62 and is pushed through the central opening 61 of the sleeve core 60 into the interior of the cardboard sleeve 57.
  • the locking rod 36 is then pushed slightly forward by the compressed air piston 37, so that the bolts 38a, b are spread out by the transverse pin 40 and project laterally outwards through the slots 40a, b (FIG. 7b).
  • the latches 38a, b are then folded in by pulling back the locking rod 36 by means of the compressed air piston 37 and the mandrel 31 is pulled back into the starting position by the compressed air piston 33 (FIG. 7d).
  • the sleeve core 60 falls into a container (not shown).
  • FIGS. 8a, b The corresponding process for a paper roll 4 without a core is shown in FIGS. 8a, b.
  • the bolts 38a, b are spread by advancing the locking rod 36 so that they engage with the entry of the sleeve 41.
  • the sleeve 41 is therefore taken against the force of the spiral spring 42 and pierces the sheath 63 and the side plate 62 (FIG. 8a).
  • the mandrel 31 is then pulled back by the compressed air piston 33 and the sleeve 41 by the spiral spring 42.
  • the sleeve 41 has a large diameter due to the rings protruding from its outside, which comes close to that of a sleeve core, so that it likewise tears a large hole in the sleeve 63 and the side plate 62 and exposes the end face 58a in the vicinity of the center.
  • the side knife 19 can now be attached to the center of the end face 58a, where the packaging has been removed. It is supported by a belt 20 along the Arms 15 are pulled radially outward, the base plate 44 of the radial knife 43 sliding directly along the end face 58a and the package being raised by the radial wedge 45 so that it either tears or comes into contact with the radial cutting disk 46 and is cut through.
  • the side knife 19 reaches the edge of the end face 58a, it abuts an inductive sensor (not shown) connected to the second button 18 and is stopped.
  • the paper roll 4 is then set in rotation by the driven support roller 5a or 5b (arrow a in FIG. 5), so that the packaging is torn open at the edge of the end face 58a by the peripheral wedge 48 of the peripheral knife 47 or cut open by the peripheral cutting disk 49. After a complete rotation of the paper roll 4, the end packaging is completely separated.
  • the movement in the longitudinal direction is then resumed, the holder 50 being raised somewhat by the positioning roller 54.
  • the brush 55 abuts the paper roll 4 in the edge area on the end face 58a, as a result of which it is pressed upwards, thereby gripping the jacket part of the sleeve 63 and lifting it slightly off the paper roll 4, so that the jacket knife 24 with the tip 52 under the Cover 63 can grip.
  • the position of the casing knife 24 relative to the casing surface 59 of the paper roll 4 can be adjusted by means of the positioning roll 54, also in such a way that it is not only under the sleeve 63 but also under the outermost paper layers the role grips and separates them with.
  • the jacket knife 24 is guided along a jacket line of the paper roll 4 and tears or cuts the cover 63 there by means of the cutting edge 53 and possibly, as said, also some paper layers over the entire length of the paper roll 4 on.
  • the sheath knife 24 is then pulled back by the compressed air piston 25 and the sheath cutting device 23 is returned to the starting position.
  • the material separated from the jacket of the paper roll 4 is now unwound and placed on the belt 27 (arrow b in FIG. 5), from which it is transported to the belt 28. where it is drawn into the slot 29 and fed to the take-up device 30, in which it is rolled into a roll which is then ejected in the axial direction.
  • the mandrel 31 of the tear-open device 17 is preferably pushed back into the cardboard sleeve 57, corresponding to that shown in FIG Fig. 8a position and then retracted into the position shown in Fig. 8b.
  • the crossbar 12 is raised by the compressed air piston 14 and the arm 15 is carried along with the tear-open device 17, the panes of the end packaging being caught on the sleeves 41 due to the protruding rings thereof and being lifted with them.
  • the Carriage 10a, b withdrawn against the portal ends and the portal 2 itself moved into the waiting position shown in FIG. 1.
  • the method and device can of course be modified in many ways. For example, it is conceivable not to cut open the casing part of the packaging and not to provide the corresponding device parts, but to carry out this step in a separate device.
