Definitions

  • the invention relates to a front cover storage and feed arrangement for a roll packaging device.
  • the storage spaces for end covers of different diameters are formed by plates which are attached one above the other on a column.
  • the plate with the front cover size just required is pivoted from the rest position into a working position, where a transport device removes the front cover and transports it to the docking station.
  • EP-A-56 237 has an end cover storage and feed device with a plurality of end cover storage locations, a lay-on station in which a front cover is fed to the end faces of a roll by a respective application head, and a transport device , which transports the end covers from the storage locations to the docking station.
  • the storage spaces are formed by drawers, which are arranged one above the other on a shelf and pulled out during use and tilted down by 90 °.
  • the transport device can remove the end cover in a vertical position and transport it to the landing station.
  • the transport device has a height-adjustable holding head which is provided with a multiplicity of suction openings with which a front cover can be removed from the drawer which has been folded out.
  • the holding head can be lowered to the height of the axis of the roller and moved axially up to the roller. Then two plugs can be pushed from opposite sides through the end caps into the sleeve of the roller.
  • DE-B-12 72 810 shows a device for wrapping paper rolls, in which a paper roll to be packed is also supplied with end covers.
  • a plurality of end cover storage locations, a placement station in which a front cover is fed to the end faces of a roll by means of a placement head, and a transport device which transports the end covers from the storage locations to the placement station are provided.
  • the end cover stacks are stacked on a lifting device that can be moved vertically in a frame.
  • the suction devices can be adjusted to the correct stack of cover plates.
  • the suction devices place the end covers on tracks on which they can slide up to a stop. From there they are removed with the help of the application heads.
  • the invention has for its object to provide a front cover storage and feeding device of the type described, in which the effort for refilling the storage spaces can be significantly reduced.
  • the storage spaces are formed by pallets carrying end covers.
  • the pallets on which the end covers are delivered can be used as a removable storage space without any repacking.
  • At least one storage space more than the number of different end cover sizes. This allows continuous operation because the additional storage space can always be filled with a stack of those end covers whose previous storage space is next to be empty.
  • the storage space lines assigned to the two end faces are arranged next to one another and the transport unit transports two end covers for the two end faces of a roll.
  • the joint transport of the end covers required at the same time with only one transport unit results in considerable design savings.
  • the transport unit runs on a lower path and is guided on an upper path.
  • the transport unit supported at the bottom and secured against tipping at the top is particularly suitable for high stacking of end covers.
  • An alternative is that the transport unit runs hanging on an upper track.
  • a lifting element which carries a suction gripping device prefferably carries a suction gripping device to be vertically adjustable on the transport unit.
  • the movement to remove a front cover is therefore made up of a vertical and a horizontal movement.
  • the transport unit can be movable next to the storage locations and can have at least one boom with the suction gripping device that spans the storage locations.
  • the transport unit can be movable next to the storage locations and can have at least one boom with the suction gripping device that spans the storage locations.
  • the suction gripping device has a plurality of suction grippers that are height-adjustable relative to the lifting element. This enables adaptation to different pallet heights.
  • the alignment station preferably has an alignment surface provided with centering stops, on which an end cover supplied by the transport unit can be displaced into the centering position.
  • the desired centering is obtained by pushing the front cover against the centering stops.
  • a particularly simple construction results from the fact that the placement station has two parallel horizontal supports for the roller and that the centering stops represent at least approximately an image of the effective support surface of the supports.
  • the end cover is given a centering position which corresponds to that of the roller on the supports. All that is then required is a translational movement to align the end cover with the roller end face.
  • the supports are preferably formed by a pair of rollers. This makes feeding the roll easier.
  • two centering stops with a convexly curved surface can be provided. This forms the effective support surface of the pair of rollers.
  • centering stops are formed by two flat surfaces at an angle to one another. In many cases this is also sufficient for centering.
  • the alignment surface can be tilted from a horizontal position into a vertical position, the centering stops being on the lower side. This tilting movement automatically moves the front cover into the correct centering position.
  • the alignment surface can also be assigned a friction-driving device which engages on the top of the front cover and moves the front cover in the direction of the centering stops.
  • the alignment surface can be formed by the contact plate.
  • the centering stops should be retractable into the surface.
  • the front cover can be transferred directly from the transport unit to the contact plate.
  • the alignment surface can be tilted into a vertical position, in which it points in the same direction as the end face of the roller, and that the application head held in a vertical position from a first position in the area of the alignment station, where it takes over the end cover , can be moved into a second position in the area of the lay-on station, where he places the end cover on the end face of the roller.
  • the front cover must first be transferred from the transport unit to the alignment surface and from there to the contact plate.
  • the movement control of the contact plate is considerably simplified since it constantly maintains its vertical position.
  • the transport unit can fetch the next front cover while the previous front cover is placed on the roll.
  • the contact plate can be attached to a lever which effects the movement from the first to the second position
  • the pivot axis of the lever can be attached to a stand in a height-adjustable manner
  • the stand can be fastened to a support which can be moved in the direction of the roller axis.
  • the contact plate can also be provided in the center with a fastening clip. In this way, the end cover can be attached to a stopper in the paper roll sleeve.
  • the operation of the drives for longitudinal, transverse and lifting movements is preferably controlled with the aid of a computer which has access to enter the diameter of the roll to be packed.
  • the transport unit controls the storage space with the appropriate end caps. If one of the transport movements is dependent on this diameter, it is specified accordingly.
  • Each storage location carries a pallet 1 with a stack 2 of end covers 3, which, as shown in FIG. 2, have different diameters.
  • the ninth storage locations S 9 and S 19 are reserve locations. As soon as the supply of end covers at a storage space pair runs out, the reserve storage spaces are filled with a new supply of this end cover size, so that continuous operation is possible.
  • the delivery pallets can be used as pallets 1. They can be transported in and out with a forklift.
  • the stack height can be up to 1.8 m, which, depending on the thickness, corresponds to up to 600 end covers.
  • a transport unit 4 runs on an upper path 5, which is arranged between the two rows of storage spaces. It can be moved back and forth along these rows in the direction of the double arrow V 1.
  • the motor for the movement V 1 is located in the transport unit 4 and is not illustrated in more detail.
  • the transport unit 4 travels to the desired storage locations, picks up a pair of end covers and transports them to an alignment station 12 or 12 '. Since these two stations are identical to one another, only the alignment station 12 is described.
  • An alignment surface 13 extends horizontally and is provided with centering stops 14, 15 in the form of surfaces standing at an angle to one another.
  • the front cover 3 transported by the suction gripper 9 is placed on this centering surface 13.
  • the alignment surface 13 is pivoted about an axis 16 into a vertical position.
  • Fig. 1 shows the alignment surface 13 during this movement.
  • the front cover 3 slides against the stops 14, 15 by gravity, so that it has a precisely defined position. In the centering position, the front cover 3 is held on the alignment surface 13 by suction.
  • a roll 20 to be packed can be placed on two rollers 18 and 19.
  • a roller 20a of smaller diameter is illustrated in dash-dot lines.
  • the centering stops 14 and 15 are arranged so that they are in the vertical position of the aligning surface 13 at the level of the rollers 18, 19 and that their stop surfaces approximately represent the contact surfaces between the rollers 18, 19 and the roller 20 placed thereon.
  • a longitudinal transport carriage 21 can be moved in the direction of the double arrow V 3 in the longitudinal direction from the fully extended position of FIG. 2 to the position 21 ′ shown in broken lines. During this movement, the alignment surface 13 comes in front of the end surface of the roller 20. The end cover then has the position 3 '.
  • a transverse transport carriage 22 can be moved in the transverse direction, that is to say in the direction of arrow V 4, on the longitudinal transport carriage 21. Since this transverse transport carriage 22 carries the alignment surface 13, the end cover can be brought up to the end surface of the roller 20 in this way.
  • the alignment surface 13 therefore also serves as an application head.
  • the end cover 3 After the end cover 3 has been attached to the roller 20, the latter is fed out of the arrangement in the direction of the arrow V 5 and fed to a further processing point. If inner covers have been attached in the arrangement shown, the roll is moved into the packaging station. The supports 18 and 19 are ready for the next roll of paper.
  • the stops 14 and 15 can be countersunk in the alignment surface 13, so that they do not interfere with the end cover being placed on the roller.
  • a transport unit 104 runs with rollers 23 on a lower track 24, which simplifies maintenance. It is also guided with rollers 25 on an upper track 26.
  • a lifting element 106 can be moved along a stand 27 in the vertical direction V 2. The drive is via a belt drive 28.
  • the lifting element 106 carries two arms 107, 108, each of which carries a suction gripping device 109 or 110 with the interposition of a pneumatic cylinder 29.
  • the suction gripping device has a plurality of suction grippers 30 on a circle.
  • a limit switch 31 is provided, which ends the lowering movement when the stack surface is reached.
  • the pneumatic cylinder 29 can be used to adapt to different pallet heights if the two pallets have one Couple do not match.
  • a tiltable plate 32 in the alignment station 112, the upper side of which forms the alignment surface 113.
  • the pneumatic cylinder 33 With the aid of the pneumatic cylinder 33, it can be pivoted from the horizontal position illustrated in FIG. 5 into the vertical position illustrated in FIG. 6.
  • It carries two centering stops 114 and 115, the surfaces of which are 34 partial cylindrical surfaces which correspond to the shape of the rollers 18, 19 in terms of diameter and mutual spacing.
  • two friction driving devices 35 and 36 are illustrated. As shown in FIG. 6, these each have a band 37 with a rough surface, which is guided over two deflection rollers 38 and 39, one of which is driven. These bands move in the direction of arrows V 6. Between the two friction-driving devices there are two suction holes 40.
  • the end covers held by the suction gripping devices 109, 110 are placed on the horizontally arranged alignment surface 113. Then they are pushed by the friction-driving devices 35, 36 against the centering stops 114, 115. The suction openings 40 are then activated and the alignment surface 113 is placed vertically.
  • a contact head 41 is provided on each side and is attached to a lever 42.
  • This can be pivoted about an axis 43 such that the center of the application head 41 moves on the circular path indicated by the arrow V 7.
  • the pivot axis 43 is attached to the actuator 44 of a lifting element 45, so that the lever 42 can be changed in height, as shown by the dashed position 42 '.
  • the lever 42 is therefore adjustable in the direction of arrow V 8.
  • Actuator 44 can be the piston of a pneumatic or hydraulic cylinder or the spindle of a spindle motor; it can also be designed in other ways.
  • the lifting element 45 is seated on a stand 46 which can be moved on a transverse transport carriage 47 in the direction of the arrow V 4.
  • the application head 41 has a series of suction holes 48 on the working side.
  • a fastening clip driving device 49 is provided, which has two outlet openings 50 and 51 with impact pistons arranged behind it, as well as associated shafts 52 and 53 for feeding the clip.
  • Fig. 8 clearly shows that the centering stops 114 and 115 coincide with the contact surfaces of the rollers 18 and 19.
  • the contact head 41 is moved to the front cover 3 by means of the transverse transport carriage 47.
  • the suction openings 48 are activated while the suction pressure from the openings 40 of the alignment surface 113 is switched off.
  • the cross transport carriage 47 moves a bit outwards. There follows the pivoting movement along the arrow V 7 over 180 °. Now the end cover 3 is located exactly in front of the end face of the roller 20. By another transverse movement of the carriage 47, the end face of the roller is pressed. In this position, the end cover can be fastened to a plug inserted into the sleeve of the roller 20 with the aid of the fastening clip drive-in device 49.
  • a smaller end cover 3a is fed in and aligned with the centering stops 114, 115.
  • the feed head 41 is lowered so far that it can grip the smaller end cover 3a.
  • the end cover in turn comes exactly in front of the end face of the roller 20.
  • the entire arrangement is controlled by a computer 54. This is entered via an input 55, the front cover sizes located in each memory location.
  • An input 56 is used to enter further data.
  • the diameter of the roll to be packaged is entered via an input 57, be it on the basis of a measurement or on the basis of a predetermined program.
  • the computer has a large number of outputs for the individual measures to be carried out one after the other.
  • An output 58 controls the motor for the transport unit 104, thus monitors the movement in the direction of the arrow V 1.
  • An output 59 ensures the lifting movement of the lifting element 104, which corresponds to the movement in the direction of the arrow V 2.
  • An output 60 outputs a correction signal to the pneumatic cylinder 29.
  • An output 61 switches the suction pressure to the suction pads 30.
  • An outlet 62 controls the pneumatic cylinder 33 and thus the tilting movement of the alignment surface 113.
  • An outlet 63 relates to the drive of the friction driving devices 35 and 36.
  • An outlet 64 controls the suction pressure at the suction openings 40.
  • Another output 65 is responsible for the actuation of the lifting element 45, that is to say the height adjustment in the direction of the arrow V 8.
  • An output 66 controls the pivoting movement in the direction of arrow V 7.
  • An output 67 is responsible for the transverse transport in the direction of arrow V 4.
  • An outlet 68 controls the suction pressure in the openings 48.
  • An outlet 69 controls the mounting bracket striker 49.
  • the outlets 58 and 65 must operate in accordance with the end cap diameter entered at the inlet 57.
  • the feed heads move outwards and swivel 90 ° into a middle position.
  • the paper roll 20 with its end caps can move out in the direction of the arrow V 5 and at the same time a new roll can be inserted either from the other side in the same direction or transversely to the rollers 18, 19.
  • the new end covers have been taken to alignment station 112, where they can then be taken over by the feed head.
  • the end covers are provided on normal pallets as they come from the delivery plant. They are roughly aligned using a hand pallet truck. This is possible without spending time and without physical effort. By using the reserve space, empty pallets can be exchanged for full ones without having to interrupt the operation. This simple provision of large quantities of lids makes work much easier.
  • the end caps had a minimum diameter of 850 mm and a maximum diameter of 1500 mm.
  • the stack height was 1800 mm.
  • the arrangements shown can be varied in many ways without departing from the basic idea of the invention. This means that all travel and lifting movements can be carried out not only pneumatically but also hydraulically or by electric motor.
  • the end covers do not have to be fastened to sleeve plugs with steel clips. They can also be clipped onto the sleeve wall. If the end covers are fed in a winding or folding station, they can be held by the feed head until the folding is finished.
  • the centering stops 14, 15 or 114, 115 can be adjustable. The shifting of the end caps required for centering can also take place in that the stops 14, 15 are pushed from an outer position into the centering position.
  • the storage locations can also be arranged on a curved line instead of on a straight line.
  • the guidance on an upper track 26 can be dispensed with. Mechanical guides on the floor or optical guides in the room can be used.
