Definitions

• the invention relates to a method for feeding a paper roll into a station for preparing a paper roll start for later connection to a running paper web and a device for carrying out the method according to the preamble of patent claim 1.
• the invention has for its object to provide a method for feeding paper rolls into a station for preparing a paper roll start of a paper roll]: for later connecting this start with a running paper web and a device for performing the method.
• FIG. 1 is a front view of a device according to the invention
• FIG. 1 is a side view of FIG. 1,
• FIG. 2nd is an enlarged view of FIG. 2nd
• a portal consisting of four vertical supports 2, 3 and two horizontally extending supports 47, 48 forms a station for preparing a paper web start of the paper roll for later gluing to a running paper web - briefly in the following
• Paper roll preparation station 1 and has two vertically arranged running tracks 4, 6 on two left supports 2, 3.
• the carriage 5 is height-adjustable in the Y direction by means of a drive.
• the drive consists of a motor 13 which is connected via shafts 14, 15 and spur gears with vertically arranged threaded spindles 17, 18, which are operatively connected to brackets 19, 21 which are firmly connected to the end face parts 7, 8 and have threaded bores.
• Support arms 23, 24 are arranged on the traverse 12 extending in the axial Z direction and can be adjusted to the width b of the paper rolls 11 in the axial Z direction.
• the support arms 23, 24 have drivable cones 26, 27 at their ends remote from the crossbeam, which cooperate in openings in a sleeve of the paper roll 11 when it is received.
• One of the cones 26, 27 can be driven by a motor, not shown.
• the support arms 23, 24 are fastened at right angles to support plates 28, 29, which in turn can be moved in the axial Z direction with the support arms 23, 24 on the crossmember 12. Between the support plates 28, 29 and the cross member 12 bearings or rollers, not shown, are arranged so that they cannot tip over.
• a pick-up bracket 31, 32 is connected to a threaded bore, which projects through slots 33, 34 extending in the axial Z direction in the cross member 12 and is provided with threaded holes outside the slots 33, 34. Threads of the threaded spindles engage in these threaded bores of the pick-up blocks 31, 32 36, 37, which are mounted in truss-fixed bearings 38. On the threaded spindles 36, 37, pulleys 39; 41 fastened, which are connected via belt drives 42, 43 to crossbar-fixed motors 44, 46, so that the support arms 23, 24 fastened on the support plates 28, 29 are adjustable in the axial Z direction.
• two rollers 53 are fastened on both sides of an upper side of the preparation device 52, which run in the horizontally extending supports 49, 51, e.g. B. double T-beams, ⁇ es portal 1 have their tread.
• the drive for displacing the preparation device 52 in the horizontal X direction is carried out by a motor 54, which, via shafts and gears (not shown), has a connection to a gear wheel 56, 57, which is attached to each carrier 49, 51 and is in a horizontal X.
• -Direction extending rack 5b, 59 meshes, so that the preparatory device 52 is movable in the horizontal X direction to the paper roll 11.
• Retract paper roll preparation station 1 The axis of rotation of the paper roll 11 then takes a position with the coordinates X., Y.
• the carriage 5 with its two support arms 23, 24 then moves from a waiting position z. B. upper, the free retraction of a paper roll 11 with for the paper roll preparation station 1 max. permissible diameter allowed when the motor 13 is actuated in the vertical Y direction downwards until the axes of rotation of the cones 26, 27 have reached the position X1, Y1.
• a known opto / electronic device is provided which determines the center of the sleeve and controls the vertical movement of the carriage 5 or the support arms 23, 24 jointly or individually so that the paper roll receiving cones 26, 27 can be retracted in the correct position.
• the support arms 23, 24 with the cones 26, 27 are moved along the coordinates X1, Y1 of the axis of rotation of the cones 26, 27 in the axial Z direction by actuating the motors 44, 46 until the cones 26, 27 of the support arms 23, 24 have securely engaged in the sleeve openings of the paper roll 11 with the width b.
• the preparation device 52 is moved in the horizontal X direction onto the paper roll 11 until the preparation device 52 comes into contact with the periphery of the paper roll 11 in a preparation position V.
• the paper roll 11 is subsequently driven by means of the driven cones 26 , 27 set in slow rotation and z. B. generated an adhesive tip by the preparation device 52.
• the processes take place in the reverse order until the prepared paper roll 11 is prepared at its beginning of the paper roll for later adhering to a running paper web. That is, he will - e.g. B. cut smooth or into a certain shape, coated with glue and connected to the first layer of the paper roll -, put back on the carriage 61 and by means of the driverless transport system a central warehouse or a paper roll 11 processing machine, eg. B. fed press.
• a simple transport device e.g. B. a so-called "von-Roll-System” can be used, so that the position of the paper roll 11 during loading in the paper roll preparation station 1 even further below the position X., Y. towards the floor, in an alternative position X, Y comes to rest.
• the device can be operated from a known control panel (not shown).
