Abstract

In a device for feeding rolled material to a glue preparation station, the problem lies in the simple way of bringing rolled material of different diameters and lengths to a central glue preparation station. According to the invention, this is done by the fact that each time a pair of support arms (36, 38) intended to receive a paper roll (43; 62) is arranged, movable longitudinally (A) and transversely, on a support, in a transport frame (11) resting on support posts (1, 2, 3, 4) or that a couple of pivoting arms is disposed between two lateral frames.

Description

A Method and device for feeding rolled material to a

  The invention relates to a method of a device for feeding roll material, for example a roll of paper, to

  a glue point preparation station.

  Roller changer devices are known

  double arm with automatic operation, in which a support arm, mounted halfway along an axis, carries at each of its ends a rollers, the new paper strip being placed on the finishing paper strip, as a result of a rotation of the roll changer around its axis and by means of an adhesive device The change of roll and thus of the paper strip is carried out in such a way that a newly received roll of paper is rotated and accelerated so that when the peripheral speeds of the new roller and the finishing roller are equal, a bonding of the new strip takes place on the finishing strip. To allow such a change of roller on the fly, it is necessary to prepare the

  glue tips from a new reserve roll.

  Such preparation of the adhesive and an associated device are described in DE 38 11 138 Ai Here, the leader of the paper strip is cut obliquely from a new reserve roll and fixed, by a fastener, on the sub-strip. overlying, in order to prevent automatic opening of the leader of the paper strip; When the production of rotary printing machines is in progress, there is a high consumption of new reserve rolls, prepared with such glue tips. For this reason, it is necessary to associate an adhesive preparation station with each automatic roll changer. The object of the invention is to create a device for bringing a material in strips, having different diameters and widths of rolls, having a small construction volume, to an adhesive preparation station, as well as to create an associated process, by means of which one can load or feed several roller changing devices. According to the invention, this problem is solved by a method characterized in that the roll of paper is transferred, for example from a driverless transport system to a lifting device, at a place where it is lifted by means of this lifting device and positioned in relation to a longitudinal displacement device or a pivoting device, then is gripped by this longitudinal displacement device or this pivoting device and brought to a known adhesive preparation station, until the paper roll comes into tangential contact with this glue preparation station and the paper roll is then moved in rotation, the glue tips then being produced The problem is also solved by a device characterized in that each time a couple of hanging support arms, intended to receive a roll of paper is arranged, movable longitudinally and transversely, on a suppo rt, in a transport frame resting on support posts, in that a known adhesive preparation station is arranged, fixed to the frame, between the support posts and by a device characterized in that each time a couple of arms pivoting, intended to receive a roll of paper is arranged in a frame resting on feet, being subjected in rotation to a swivel shaft in the frame, in that the shaft has at its ends legs locked in rotation, in that that the pivoting arms are capable of pivoting at an angle, by means of jacks

  arranged between the side frames and the legs.

  When using the invention, the following advantages are obtained in particular: By supplying several automatic roller changing devices, equipped with new paper rolls with glue tips prepared by a central glue preparation station , the size of the construction of the printing machine is not changed. The device according to the invention, installed in an off-center manner, the construction of which is compact, can be introduced simply into an existing transport system. of the device according to the invention, it is possible to prepare the adhesive layers at a high rate, independent of the operating state of the roller changer The diameter as well as the width of the rollers

  paper to prepare can be changed.

  The degree of use of a glue station arranged in a decentralized manner is significantly higher than for stations associated with each roll changer. A decentralized embodiment has the advantage that in the case of several devices of this type, being in there is always the possibility of change. The invention is explained in more detail using several embodiments In the accompanying drawings Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Figure 9 shows a front view of a device according to the invention; shows the side view of Figure 1; shows the top view of Figures 1 and 2; shows the front view of a second alternative embodiment of a device according to the invention; shows a side view of Figure 4; shows a top view of Figures 4 and; shows the front view of a third alternative embodiment of a device according to the invention; shows a side view of Figure 7; represents a top view of FIGS. 7 and 8.

IV shows a position for waiting for the support arm 36; 38 shown in dotted lines, position for which a carriage 63; 64 loaded with a roll of paper can enter or exit, in the direction of arrow B, without entering

  collision with the support arms 36 to 39 (Figure 2).

  The device works as follows: A carriage 63 of the driverless transport system moves a roll of paper 43 through the induction loop system 68 represented in FIG. 3, to go to the axial position III represented The arms supports 36; 37 (the support arm 37 is not shown in FIG. 1) are in the waiting position IV, near the support posts 1; 5 Now, the support arms 36; 37 are moved in the direction of arrow A, by means of the drive 33, to pass to the receiving position II The lifting table 69 of the carriage 63 is lifted by the value of the level difference between III and II, up to '' that the photocells 44 identify the reaching of

  position II using the position of the socket 42.

  After the lifting table 69 has moved the paper roll 43 to position II, with its bush 42 disposed axially, the support arms 36; 37 approach each other by means of the drives 51; 52, so that they engage by their cones 41 in the socket 42 Now the drive 33 moves the support arms 36; 37 in the direction of arrow A, in the axial position I, in which the paper roll 43 is in tangential contact

  with the device 56 for preparing the glue tips.

  The device 56 works in the manner indicated in DE 38 11 138 Ai The geared motor 59 then puts the paper roll 43 in rotation, as necessary After constitution of the adhesive bridges, the paper roll 43 is successively placed in the positions I and III The support arms 36; 37 move away from the

  direction B and take the waiting position IV again.

  The carriage 63 moves the paper roll 43 provided with a glue point to another location. The device 56 can meanwhile be provided in a similar manner with another paper roll 62, for example a smaller paper roll. An embodiment of a device according to the invention is shown in Figures 4 to 6 There are differences here in the variant shown in Figures 1 to 3 of the shortened embodiment of the supports 11; 12 and in the arrangement of the external support posts 1; 4; 6; 9 This device is thus of a more compact embodiment. The carriages 63; 64 must penetrate in the longitudinal direction A and receive from the induction loop 68 scrolling in the direction B an impulse, in order to move in the direction A It is not necessary to have a waiting position IV of the support arms 36 to 39 The same reference numbers are used

than in Figures 1 to 3.
