Description

  The present invention relates to a method and a

  positive handling of paper rolls for a rotary printing machine which is provided for this purpose with several separate supports for receiving the coils; these come from a reserve store and are transported in a known manner by a transport system, to a preparation station disposed before each of the aforementioned carriers; each coil is then introduced into the corresponding support, then removed from the support after consumption, to be taken to a

  deposit planned for the reels consumed.

  Handling methods are known to thereby bring paper rolls up to the supports provided for

  In the conventional mode of handling the reels to serve the supports provided for receiving them, it operates with a known means of transport to take an unwrapped reel at the location of a preparation station, and bring it facing the support o it is a question of introducing it; Then, the coil is loaded by rolling it between

machine uses.

  In another known method, there is a reel preparation station in the transport system which serves to convey the reels from the magazine to the machine feed support. But the

  With an installation carried out in order to implement the proposed method, it is possible to carry out automatically the elementary maneuvers for setting up the new coils and for unloading the coils.

of the printing machine.

  We will now describe the process according to

  the invention, to ensure the handling of the bobbins

  paper sleeves used by a rotary printing machine, with reference to the single figure of the drawing

  Annex, which represents, by way of example, no

  tative, an embodiment of the corresponding device.

  Schematised in the figure a series of sup-

  ports 9 for paper rolls, provided, for example, under a rotary printing machine, with several

  printing units, to power this machine with

bins of paper.

  The system under consideration comprises five transport lines a, b, c, d and e, for unloading and placing the reels. Each of the lines a, b, c, d, e, is associated with a turntable 1, which is part of a transport loop 2 on which the coils are moved by means of rails 3, which serve the transport lines a. , b, c, d, e, and carriages 4 which roll on the rails. The carriages 4 serve to bring the new coils 5 from a magazine (according to the arrow 6),

  to convey them through a turntable

  1 to one of the transport lines a, b, c, d, e.

  Each of the lines a, b, c, d, e comprises a transfer station 7, a transfer system 8 for the coils, a support 9 for receiving these, a plateau

  sliding lift 10, and a discharge system

  11 to evacuate each consumed coil 17.

  The transhipment station 7 has two rollers

  12 and 13, whose axes are parallel to that of the

  paper 16 to move. These two rollers can lift, and one has a rotational drive device, which allows to rotate a little the coil of

  new paper carried by the two rollers 12, 13.

  The transfer system 8 which serves to evacuate each

  consumed coil 17, includes rails 14 on the

  which rolls carriages 15, provided with a drive device. The support 9 is provided to receive two coils and for this purpose has sufficient space and a system

  which makes it possible to connect the bands of pa-

  pier of both coils, by gluing, in a known manner.

  The sliding lifting plate 10 serves to take the new spool 16 discharged from the carriage 15, to bring it

  under the arms of the associated support 9, and to lift

  following the reel up to the necessary height. Similarly,

  the support 9 is unloaded from the residual part 17 of each

  the reel consumed, to ensure that it is removed at least once

reels consumed.

  The unloading system 11 has a mechanism

  pushbutton 18, which serves to pass each coil con

  summed 17 on the carriage 4 of the transport loop 2, to

  from the carriage 21 which is part of the transmission system.

  8. Between the transfer station 7 and the sliding lift plate 10, a

additional waiting 19.

  Before starting the printing machine, all the paper rolls are prepared. For this purpose, he

  must have two coils in each support 9 corres-

  laying on one of the transport lines a, b, c, d, e,

  one of these coils being provided with a bonding zone.

  On the carriage 15 which is in the waiting location 19, a coil 16 has been loaded, the gluing area of which has been prepared. The rollers 12 and 13 of the transfer station 7, which also serves as a waiting station, have been placed in the upright position after having loaded a

  paper reel also provided with a zone of colla-

  ge. It is in this starting situation that we begin

  to operate the printing machine.

  When the first coil of the support 9 has been

  When fully consumed, the beginning of the second reel tape is automatically connected by gluing to the end of the tape of the first reel. We do

  then rotate 180 the shafts of support 9, and the first

  first consumed coil 17 is then next to the

  sliding lift plate 10 of the transmission line

  corresponding port, such as line "a" in the figure.

  The carriage 21 is brought onto the sliding lifting plate 10; the tray carrying the carriage 21 is then

  brought under the axis of the consumed coil 17, and it is

  raise to take this consumed coil. We lower

  following the plateau 10 to its starting position, and the

  carriage 21 carrying the consumed spool 17 moves

  the unloading system 11, where the push mechanism

  evening 18 intervenes to pass the consumed coil 17 of the carriage 21 to the carriage 22, as schematized on

the transport line "b".

  The paper reel 23 which has been prepared the bonding area is ready on the carriage 24, at the location of the waiting station 19. It is then advanced to the sliding lifting plate 10, and it raises to be able to engage the clamping pins of the arms of the support 9 in the hub of this new coil 23. This lifting movement of the tray can be monitored

  slide 10 by means of a photocell system

  31. Then, the tray 10 is lowered

  to its starting position. At the same time, the evacuation carriage 22 carrying the consumed spool 20 passes

  the turntable 34, to pass on the transmission loop.

  The carriage 26 starts from the slidable lifting platform, so that it can be placed under the reel 27 which rests on the rollers 12, 13, of the transfer station 7, where it has been placed in the upright position. these two rollers which at the same time ensure the correct axial orientation of the coil 27. The carriage 26 then takes this coil which

  has a bonding zone, and moves to the position

port "a".

  The carriage 28 then brings a new reel of paper 29 from the reserve magazine, and passes the

  by the ramp 30 terminating in lane 31, where

  riot 28 is brought into an unloading system 11 so

  take a consumed coil 17 to evacuate in turn.

  This operation occurs, for example, on the line of

  of the printing machine. We know, moreover, that

  it does not consume paper reels at intervals

  In order to ensure the entirely automatic operation of the installation just described, it is necessary to incorporate monitoring devices in a known manner so as, for example, to monitor on a board the sequence of events. of those operations that are
