Definitions
- the invention relates to an apparatus and method for the transport of web-like material, in particular printed webs or packets of printed webs fed from a fold former positioned downstream of a printing machine with a roll that can be driven and against which pressure-application rolls can be adjustably pressed.

Abstract
Description
- This application claims the priority of German Patent Document No. 10 2005 042 439.2, filed Sep. 7, 2005, the disclosure of which is expressly incorporated by reference herein.
- The invention relates to an apparatus and method for the transport of web-like material, in particular printed webs or packets of printed webs fed from a fold former positioned downstream of a printing machine with a roll that can be driven and against which pressure-application rolls can be adjustably pressed.
- The pressure-application rolls together with the driven draw-rolls, form an in-draw gap. It is necessary, therefore, to take measures to effectively prevent the risk of fingers being crushed. In the known arrangements a protective hood is provided for the pressure application rollers. This certainly offers adequate protection against the risk of fingers being crushed. It is a disadvantage, however, that the protective hood prevents a clear view being obtained of the in-draw gap and of the transported web material. A quite special disadvantage is that the space between a protective hood and a pressure-application roll can become smaller which leads to the pressure-application roller being blocked. Experience has shown that when webs of paper are being processed so-called spaghetti-formation often develops as a consequence of the faulty adjustment of slitting knives, etc., in that the spaghetti collects between one or more protective hoods and the associated pressure-application rolls and block them after a period of time. This results in the affected pressure-application rolls grinding on the driven draw-rolls which leads to the flattening and, consequently, to the destruction of the pressure-application rolls.
- Taking this as a starting point, it is therefore the object of the present invention to improve an arrangement of the type described above with simple and economic means such that the use of a protective hood can be dispensed with while nevertheless providing adequate protection against the risk of fingers being crushed.
- This objective is achieved according to the invention in that the pressure-application rolls are carried by a relevant assigned position-setting assembly which exhibits at least one actuating element capable of receiving an impulse from a pressure-applying agent, where the impulse from the pressure-applying agent can be controlled according to a pre-settable timing sequence by a control device.
- These measures offer the possibility in an advantageous manner that the position-setting procedure does not have to operate suddenly as before but rather that it can proceed comparatively slowly and/or in several stages. This ensures that that an operator, who when adjusting the setting of the pressure-application rolls—an activity which in many cases requires direct vision of the relevant pressure-application roll—must insert his/her fingers into the danger area to detect the adjustment movement of the pressure-application roll, has sufficient time to withdraw his/her fingers before the position-setting procedure is completed or the full application of pressure takes effect. It is possible, therefore, advantageously to dispense with all other protective measures. Also advantageously, there is consequently no longer any danger that a pressure-application roll can be blocked in the event of spaghetti build-up and destroyed as a result. In addition to providing a high level of working safety, the measures according to the invention accordingly guarantee a high level of process security and freedom from the risk of breakdown which has a beneficial effect upon the overall economic situation.
- Thus, the control device can expediently exhibit a control valve which is designed as a proportioning valve and arranged in a supply line which provides a pressure-applying agent and is assigned to the position-setting assembly. With the assistance of a proportioning valve it is possible to achieve in an advantageous manner not only any desired timing sequence but also any desired final level of applied pressure—and to do so in a simple way.
- A further extension of the present invention is that the control valve can be controlled by a memory-endowed computer in which the desired timing sequence together with, preferably the desired level of applied pressure is stored. This ensures an automatic implementation of the position-setting procedure. A further advantage is that in the event of a change in the desired timing sequence, etc., only the relevant software needs to be amended. It is therefore possible to adapt to the circumstances of the individual situation in a simple manner.
- In a further extension of the present invention, the position-setting assembly can exhibit a housing block with two projectable pistons where each one seals off a working space which can receive an impulse from a pressure-applying agent and where the ends protruding out of the housing block are connected by a yoke upon which is securely mounted at least one appropriate axle carrying at least one pressure-application roll. The twin pistons provided here with the yoke carrying the axle provide a high degree of stability and consequently very smooth running of the pressure-application roller. In addition, the integration of the cylinder-piston frame in a housing block results in a very compact arrangement.
- A further expedient advantage can be that at least one return positioning spring in the housing block is assigned to the yoke. Consequently, the piston can be designed as simple operating pistons which permits a simple form of construction.
- Further advantageous developments and expedient extensions of the overriding measures of the present invention are provided in greater detail in the example description below and by reference to the drawings.
- In the accompanying drawings:
-
FIG. 1 shows a partial view of the upper part of a folding section with a fold former and an associated in-draw arrangement; -
FIG. 2 shows a pressure-application roll with an associated position-setting assembly in the fully engaged position; -
FIG. 3 shows the arrangement according toFIG. 2 in the disengaged position; -
FIG. 4 shows an applied pressure/time diagram; and -
FIG. 5 shows a view of a pressure-application roller arranged so as to be laterally displaceable. -
FIG. 1 illustrates a fold former 2 arranged in theupper part 1 of a folding section to which a web packet consisting of several webs imposed upon one another is directed and which come from an upstream printing machines not shown in any greater detail here. For this purpose, the individual webs leaving the printing machine run over a so-called harp consisting of several in-feed rolls 3, thedeflection rolls 4 and the in-draw devices 5 arranged successively. Each of the in-draw devices 5 consists of a draw-roll 7 extending the full width of the machine and powered by an assigneddrive motor 6 where adjustable pressure-application rolls (trolleys) 8 can be pushed against the draw-roll. The pressure-application rolls 8 are mounted on freely rotating bearings and rotate solely under the influence of friction. - The pressure-
application rolls 8 can be positioned against or away from the relevant assigned draw-roll 7. All the pressure-application rolls 8 or selected pressure-application rolls may be involved. To serve this purpose, the pressure-application rolls 8 are mounted in a position-setting assembly 9 which permits the pressure-application roll 8 to move at right angles to its axis. As can be seen fromFIGS. 2 and 3 each position-setting assembly 9 contains ahousing block 10 with an integrated cylinder-piston arrangement to effect the desired adjustment of the assigned pressure-application roll 8. To that end, thehousing block 10 is provided with two bored holes which run in the engaged and disengaged position-setting direction. These holes are closed at the rear by afitting 11 and each of them is penetrated internally by a length of shaft functioning as a piston 12 which together with the fitting 11 demarcates a workingspace 14 which can be dynamically filled through asupply line 13 by a pressure medium, preferably compressed air. The ends of the pistons 12 remote from theworking space 14 protrude out of thehousing block 10 and they are connected to one another by ayoke 15 forming a portal-like configuration which guarantees high stability. A protrudingaxle 16 is secured to theyoke 15 on which the relevant assigned pressure-application roll 8 is mounted in a manner permitting free rotation. Theaxle 16 is flatted where it sits on theyoke 15 to provide plane contact surfaces. - The pistons 12 are designed as simple working pistons which when pressure is applied to the relevant assigned
working space 14 are pushed away from the basic driven-in position illustrated inFIG. 3 to the basic driven-out position illustrated inFIG. 2 . The reverse motion is effected by a return positioning spring 17. To facilitate this thehousing block 10 is provided with a centralbored hole 18 into which apin 19 attached to theyoke 15 penetrates. The yoke side of thebored hole 18 is closed by a fitting 20 which is pierced by thepin 19. The side of thepin 19 that is remote from the yoke is provided with aspring plate 21. The return spring 17 is supported on one side by the fitting 20 and on the other side by thespring plate 21. In the course of the position-setting procedure, i.e., when driving out the pistons 12, the return positioning spring 17 is compressed. As soon as the pressure in theworking spaces 14 drops, the return positioning spring 17 pushes back theyoke 15 and the pressure-application roll 8 carried upon it from the basic engaged position shown inFIG. 2 to the basic disengaged position shown inFIG. 3 in which the pistons 12 are driven up to the stop on the rear-mountedfittings 11 in thehousing block 10. - In order to prevent any risk of fingers being crushed, the position-setting movement of the pressure-
application rolls 8 does not take place suddenly, but rather, slowly and or in several stages with increasing speed. To that end, as depicted inFIG. 2 , acontrol valve 22 is arranged in thecommon supply line 13 from a source of pressure which is not illustrated in any more detail to the twoworking spaces 14 in thehousing block 10. Expediently, this valve is designed as a proportioning valve and by its use the generation of pressure in theworking spaces 14 can be controlled such that a desired timing sequence is obtained for the generation of pressure in the working spaces and, consequently, of the setting and application of pressure upon the pressure-application rolls 8. Acontrol device 23 is provided to activate thecontrol valve 22, which control device expediently contains a computer into the memory of which the desired timing sequence can be stored. - As mentioned above, the generation of pressure in the
working spaces 14 and, correspondingly, the execution of the position-setting procedure can proceed slowly or in several stages. A multistage position-setting and pressure-application procedure is illustrated inFIG. 4 . Thefunction 24 depicted schematically inFIG. 4 schematically shows the course of the level of applied pressure with time. - In a first stage here, the pressure-
application roll 8 is placed against the assigned draw-roll 7 with no or negligible force. In a second stage there is a progressive increase in the level of applied pressure up to a desired norm value which develops in a linear or slow manner. It is expedient if in the first stage the level of applied pressure is only slightly higher than the return force exerted by the return positioning spring 17. The selected norm value for the second stage, i.e., the final application pressure, can also be stored in the memory of the computer. In the case of different product situations, e.g., wide format or tabloid format, different norm values can be stored so that the norm value can also vary. - The first stage can be started by a switching procedure where the pressure rises comparatively quickly to the abovementioned strength of the return positioning spring 17, which is indicated by the stage “s”. Continued switching from the first to the second stage can result from a time-function element in the
control device 23 which is initiated at the beginning of the first stage and continues the switching procedure at the end of the second stage. It is also conceivable to arrange for the further switching procedure from the first to the second stage to be dependent upon the operating circumstances of the printing machine, for example, the instant of the first instruction to run, i.e., the commencement of printing. To achieve this, thecontrol device 23 can be connected to the control system of the printing machine as is indicated by aninput 25. To facilitate a manual start the control device is provided with aninput 27 connected to aswitch 26. The first stage can also be started by this means. It is also conceivable to start the first stage automatically in dependence upon the operating circumstances of the printing machine, for example at the completion of the feed-through operation. - Once the second stage has commenced, the pressure rises comparatively slowly along the ramp “r” to the abovementioned norm value. In the illustrated example the ramp r is linear. A non-linear or stepped rise is, however, also conceivable.
- The pressure-application rolls 8 are positioned only in the pressure-free areas of the relevant web in motion. Correspondingly, the pressure-application rolls 8 can be arranged to be adjustable over the width of the machine. To that end and as can be seen from
FIGS. 1 and 5 , each position-settingassembly 9 which carries a pressure-application roll 8 is provided with acarriage 28 which accepts theappropriate housing block 10 and which is displaceably mounted on atraverse 29 extending across the width of the machine. The position of thecarriages 28 can be changed either manually or by powered means, for example by a motor-driven threaded shaft, and then locked in the desired position. This is effected by a clamping device which is shown inFIG. 5 only by itsactivation lever 30. - In the illustrated example the clamping device for locking the relevant assigned
carriage 28 is operated manually by theactivation lever 30. In the case of motorized adjustment of the position of thecarriage 28 it is also possible to provide mechanically operated locking by, for example, an electromagnetic device. -
