Definitions

  • the invention relates to a device for forming a sequence of underlapping, flat objects, in particular for forming a scale flow when conveying sheets cut from a paper web by means of an upstream cross-cutting device to the feed table of a sheet-processing machine, with a holding device arranged above a belt arrangement, with which the rear area of the successive objects can be brought into engagement by means of an associated lifting device, preferably by means of an associated lifting device, and with a pulling device which is arranged downstream of the belt arrangement and can be driven at a shingled stream speed.
  • a device of this type is known from DE 29 02 447 C3.
  • the holding device contains only a stationary suction box.
  • the belts of the belt arrangement overlapped by the suction box are simple conveyor belts on which the sheets to be transported merely rest. There is no need to take the sheets with you.
  • the holding device designed as a stationary suction box can therefore only come into action when the sheet in question has already been gripped by the subsequent pulling device and has accordingly already been braked to scale speed. There is therefore a risk that the sheet practically pushed by the belt arrangement will run onto the pulling device at high speed, which can lead to damage to the leading edge of the sheet and to inaccuracies. This danger becomes more acute with increasing machine speed.
  • the belt arrangement is designed as a towing device with revolving drivers which grasp the successive objects only in the region of its front end
  • the holding device has a braking device with revolving holding means which can be brought into engagement with the rear ends of the successive objects and which can be driven at variable speed initially corresponds to the transport speed of the drivers of the belt arrangement and, based on this, can be reduced to the scale flow speed.
  • the belts of the belt arrangement can be driven at a speed that is variable over their circulation, which, based on a speed corresponding to the speed of the arriving objects, increases to a transport speed that is higher than that and then synchronizes the drivers with the arriving objects accomplishing Return speed is adjustable.
  • a further expedient measure can consist in the fact that the belt arrangement has several, preferably two sets of belts which can be driven independently of one another, each with the same, temporally offset speed profile, and whose drivers can be brought into engagement alternately with successive objects.
  • An alternating use of this type advantageously facilitates the control of the drive devices assigned to the belts of the belt arrangement, even at extremely short cycle times, and at the same time ensures high accuracy with regard to the synchronization of the drivers with the respectively assigned objects.
  • a further, particularly preferred measure can consist in the fact that the belts of the towing device are designed as suction belts which are only partially provided over their circumference with suction holes arranged in the form of at least one suction hole field.
  • the suction belts forming the towing device can advantageously be driven in a form-fitting manner, preferably in the form of a toothed belt with teeth pointing inwards. This measure ensures high accuracy despite the required acceleration and deceleration of the belts forming the towing device.
  • the suction belts of the towing device can expediently be raised in the area of their suction fields. This measure proves to be particularly preferred when using a plurality of sets of tapes with mutually offset carriers, since this makes it possible to avoid contacts between the object carried by the respectively activated set of tapes and the tapes of the other set of tapes.
  • the belts of the towing device can be provided with their deflecting cams, which protrude upward and run ahead. These deflection cams also keep a gap open in the case of sagging bends into which the following bends can be dragged by the drivers of the towing device.
  • the pulling device can be paired with one of the rollers drivable drive rollers and preferably spring-loaded counter rollers limited clamping gap can be formed, against which the belts of the towing device are sunk.
  • a further advantageous embodiment of the superordinate measures can consist in the fact that the holding means of the braking device are designed as suction belts which can be driven all round and are provided with suction holes over their entire circumference. This advantageously results in simple self-control in such a way that the suction holes gradually pass over the end of the assigned suction channel.
  • the use of suction belts enables the speed of the belts of the braking device to be easily matched to the speed of the belts of the towing device.
  • the suction belts of the braking device can also be designed as form-fit drivable belts, preferably in the form of toothed belts with teeth pointing inwards, which ensures high accuracy without slipping losses.
  • the holding device can have a suction box which is arranged downstream of the braking device and is stationary during operation. This enables the inlet gap to be kept open even after the braking process has ended.
  • the complete holding device including the associated braking device can be arranged stationary during operation, which results in a high level of vibration security even with a large machine width.
  • the entire holding device and any associated lifting device can be adjustable depending on the format.
  • a sheet-processing machine such as a sheet-fed printing machine, is supplied with the sheet-shaped material in a manner known per se in the form of a stream of shingles, which is produced during the processing of sheet stacks during the processing of the stack.
  • a paper web 2 is unwound from a roll 1, from which sheets 4 are cut off by means of a cross-cutting device 3.
  • These are brought together to form a scale flow 5 by means of a scale unit to be explained in more detail below.
  • This can be introduced straight into the sheet feeder or, as indicated here at 6, after appropriate deflection, into a sheet feeder, which delivers the sheets fed to the sheet processing machine in cycles.
  • the above-mentioned dandruff unit contains, as can be seen from FIG. 2, a belt arrangement 7 adjoining the cross cutter (not shown here in more detail), through which the sheets separated from the paper web are transported such that the respective subsequent sheet 4a with its front end under the rear end of the leading sheet 4b is dragged in.
  • the sheet entrained by the belt arrangement 7 is first accelerated with respect to the speed of the paper web. This is then slowed down to the shingled stream speed. This is predetermined here by a pulling device 8, which is arranged at the front end of the towing distance covered by the belt arrangement 7.
  • the rear end of the respectively leading sheet 4b is raised with respect to the transport plane of the belt arrangement 7.
  • the preceding sheet 4b is braked to the shingled stream speed, so that the following sheet 4a shoots into the inlet gap.
  • a holding-up device 10 is provided above the belt arrangement 7, which sucks up the sheet located below, here the sheet 4b, holds it up and at the same time brakes it to the shingled stream speed.
  • the holding device 10 consists of two units arranged one behind the other in the form of a suction box 10a having a fixed suction surface and a braking device 10b arranged upstream thereof with movable braking members.
  • a lifting device 11 is used for this purpose, which brings the sheet to be lifted into engagement with the holding device 10, which in this case can be arranged stationary.
  • the lifting device can be a blowing device or, as shown here, a patch device, or a lifting suction device acting from above.
  • the braking device 10b could, for example, carry out a corresponding lifting movement.
  • the belts of the belt arrangement 7 are designed as suction belts 12 of the type best shown in FIG. 3.
  • Each such suction belt 12 is assigned a suction channel 13 formed by a hollow profile, on which the upper run of the suction belt 12 in question rests.
  • All suction channels 13 of the belt arrangement 7 are connected to a vacuum source, not shown here, via a common distributor chamber or, as here, via individual lines 14.
  • Each hollow profile containing a suction channel 13 is provided in the region of its upper wall with a preferably central suction opening, here in the form of a slot 15, or a row of bores, etc.
  • the suction belts 12 are provided with suction holes 16 communicating with the suction opening.
  • suction belts 12 are not provided with suction holes 16 over the entire length, but only partially. Accordingly, suction hole fields 17 are distributed evenly around the circumference and are spaced apart from one another form drivers which can grasp in the sheet that comes into engagement in the area of its front end and can be dragged.
  • the belt arrangement 7 accordingly functions as a towing device through which the sheets 4 are transported in a towing manner.
  • the suction hole fields 17 acting as drivers can have a length of 150 to 250 mm, preferably 200 mm. Between the individual suction hole fields 17, the suction belts 12, as can be seen in FIG. 3, have no suction holes. In the area of the suction hole fields 17, the suction belts 12, as can further be seen in FIG. 3, can have an elevation 18. This results in an increase in the contact surface of the sheet 4 captured by the relevant suction field 17, which is particularly desirable when the suction belt arrangement 7 has a plurality of sets of suction belts which are used alternately. As a result of the elevations 18, these do not come into contact with the sheets 4 towed by the other set of tapes, so that speed profiles offset from one another are possible without risk of damage.
  • the suction belts 12 are provided with deflection cams 19 which project upwards and are arranged in the region of the front ends of the suction hole fields 17.
  • a deflecting cam 19 also provides sufficient free space in the event of a sag of the sheet located above it, for example in the region of the front end region of the active towing section of the belt arrangement 7 which acts as the towing device and which is adjacent to the pulling device 8 for one sheets 4c which are already in engagement with the pulling device 8 and which are dragged from behind and overlap from behind, here sheets 4b.
  • the deflecting cams 19 can be formed as bumps which are molded onto the suction belts 12 and lead to the suction hole fields 17.
  • the suction belts 12 run into the pulling device 8, whereby, as FIG. 2 further shows, in the case of a clamping gap 20 there, the suction belts 12 are lowered at least by the height of the deflection cams 19 relative to the clamping gap 20, so that they do not collide with the clamping gap 20 forming elements, here in the form of driven drive rollers 8a and resiliently can be pressed against these pinch rollers 8b. At the same time, this also results in a leading edge for the incoming sheets.
  • a band kink or a band deflection is provided in the area of the pulling device 8 in order to accomplish the above-mentioned band lowering, wherein deflecting elements 21 which are arranged coaxially to the drive rollers 8a but have a smaller diameter are used, as can be seen from FIG.
  • the length of the active towing section of the belt arrangement 7 functioning as towing device is predetermined by the length of the suction opening, here in the form of the central slot 15, of the suction channels 13.
  • the suction belts 12 run at the speed of the paper web 2 at the time of picking up a sheet. After a sheet has been picked up, it accelerates to a higher speed Transport speed, so that there are gaps between the successive sheets. At this speed, the suction hole fields 17 acting as drivers drive over the front transfer point 15b. At the same time, however, the sheet released in this way is held at its rear end by means of the braking device 110b in such a way that braking to the scale flow speed predetermined by the pulling device 8 takes place.
  • the suction belts 12 in question move back in such a way that the next suction hole field 17 arrives in phase with the respectively assigned sheet at the takeover point 15a.
  • This return movement can be faster or slower than the transport speed.
  • the suction belts 12 of the belt arrangement 7 are accordingly driven over their circulation at a variable speed, so that a speed profile results over their circulation.
  • the suction belts 12 are designed as toothed belts with an inward direction Teeth 22 formed.
  • the drive or deflection wheels 21 are designed as toothed belt wheels.
  • slip losses are excluded.
  • the outside of the band opposite the teeth 22 acts as a flat contact surface.
  • suction holes 16 are provided only in the area of the belt center, which communicate with a central suction opening, here in the form of the slot 15, of the assigned suction channel 13.
  • a central suction opening here in the form of the slot 15, of the assigned suction channel 13.
  • widened surface recesses 23 are provided in the area of the suction hole areas 16, into which the suction holes 16 open.
  • the suction opening here in the form of the slot 15, is delimited by lateral sealing strips 24 on which the respectively assigned suction belt 12 runs.
  • the sealing strips 24 can be provided with expansion grooves. Outside the sealing strips 24 there are lateral grooves 25 for the teeth 22 of the respectively assigned suction tape 12. Accordingly, they do not go through the bandwidth here, but only form two rows of teeth lying on the outside.
  • running resistance increases. In the embodiment on which FIG. 4 is based In contrast, there is a comparatively low running resistance.
  • the belt arrangement 7 functioning as a towing device can have a plurality of sets of belts which are used alternately and whose speed profiles are accordingly offset in time from one another.
  • the belt arrangement 7 has two pairs of suction belts 7a, 7b which form a set of belts and which operate alternately, that is to say their speed profiles are temporally offset and their suction hole fields 17 which act as drivers are offset locally so that the successive sheets alternate from one or the other other bands 7a and 7b are detected.
  • a separate drive motor 26a or 26b is assigned to each pair of belts 7a or 7b, as FIG. 5 further shows.
  • the two drive motors 26a, b can be controlled by means of an associated control line 27a or 27b in such a way that the desired speed profile and the desired profile offset are achieved.
  • the drive motors 26a, b mentioned are each connected to a shaft 28 or 29 which receives the rear or front deflection members 21 of the suction belts 12 belonging to each belt set.
  • the deflection members assigned to a set of straps are fastened, as indicated at 30, and the deflection members assigned to the respective other set of straps are freely rotatable, as indicated at 31.
  • the deflection members fastened on the respectively assigned shaft act as drive wheels, the freely rotatable deflection members merely as deflection wheels.
  • the band elevations 18 provided in the area of the suction hole fields 17 have a positive effect, since this ensures that the other belts running at relative speed to the sheet 4 resting on such an elevation 18 do not touch the underside of the sheet.
  • a pulling device 32 without a gap is used.
  • This is a belt arrangement which is arranged downstream of the belt arrangement 7 functioning as a towing device and which has a plurality of conveyor belts 32a running uniformly at the shingled stream speed. These can be designed as suction belts with suction holes provided over their entire circumference.
  • the belts of the belt arrangement 7 are submerged below the transport plane of the belts of the belt arrangement forming the pulling device 32.
  • the bands of the band arrangement 7 are deflected downward in the region of a kink.
  • a roller 33 with protruding stops 33a can be provided in the region of the interface of the two transport planes, against which the leading edges of the incoming sheets braked by the braking device 10b of the holding device 10 can run.
  • the stops 33a run at the speed of the belts 32a and accordingly also at the shingled stream speed.
  • the pulling device 32 and the roller 33 provided with stops are driven, as can further be seen in FIG. 5, by means of a lateral longitudinal shaft 34 which, with the interposition of a reduction gear, is driven by a so-called single-speed shaft which runs in time with the sheet-processing machine.
  • the pulling device 8 which is based on FIG. 2 and is designed as a pair of rollers, can also be driven. The same applies to the lifting device 11 indicated in FIG. 2.
  • the holding device 10 consists, as has already been explained in connection with FIG. 2, of a suction box 10a which acts as a towing device and which acts as a towing device, which also holds the sheets sucked up when their front end has already been transferred to the pulling device, and one Upstream suction box 10a, d. H. opposite to the transport direction, there is a braking device 10b which brakes the sucked-in sheets so that they enter the tightening device at a shingled stream speed.
  • the braking device 10b is provided with circumferential braking members 35 which come into engagement with the successive sheets before the sheet is transferred to the pulling device.
  • the circumferential braking members 35 can be suction belts which can be provided with suction holes over their entire circumference. As can best be seen from FIG. 7, it is useful to provide a plurality of braking members 35 distributed uniformly over the machine width.
  • the suction belts forming the braking members 35 can be individually interconnected suction channels.
  • a common suction box 36 is provided which extends over all assigned suction belts and is connected to a vacuum source via a connecting line 37.
  • the suction box 36 is closed with a base plate on which the lower run of the suction belts forming the braking members 35 runs and which is accordingly provided with suction openings in the form of slots or rows of holes in the area of the tracks assigned to these suction belts.
  • the rotating suction belts forming the moving braking members 35 are driven via a countershaft 38 by means of an associated motor 39 accommodated on the frame of the braking device 10b or holding device 10.
  • this is a speed-controllable motor which can be controlled via a control line 39a in such a way that a desired speed profile can be achieved.
  • the lifting device 11 is adjusted so that the rear end of each sheet 4 is only brought into engagement with the braking members 35 when the associated belts of the towing device have reached the increased transport speed compared to the speed of the paper web.
  • the braking members 35 of the braking device 10b are driven at the same speed as the respectively active belts of the belt arrangement 7 functioning as a towing device.
  • the arc engagement of the braking device 10b accordingly takes place smoothly.
  • the speed of the braking members 35 is reduced in such a way that the scale flow speed is reached when the front end of the sheet reaches the pulling device running at the scale flow speed or shortly before. Since the suction holes 16 of the suction hole field 17 leading the relevant sheet in its front end extend towards the end of the towing distance beyond the front end 15b of the suction opening of the associated suction channel 13, the gradually released sheet in this area follows the suction belts of the braking device.
  • the belts of the lower belt arrangement 7 now only function as support belts which pass under the relevant sheet at a certain relative speed, so that the latter extends but enters the pulling device at the speed of the braking members 35, which corresponds to the scale flow speed.
  • the release of a rear arch end by the braking members 35 can accordingly take place if the associated front arch end has already run into the pulling device.
  • the distance of the braking device 10b from the pulling device which in turn is formed as a pair of rollers in FIG. 6 and is accordingly also designated 8, accordingly corresponds at most to the arc length and is preferably somewhat less.
  • the suction belts forming the braking members 35 are designed as toothed belts with inwardly directed teeth.
  • the associated deflection members 40 are accordingly designed as toothed belt pulleys.
  • a positive torque transmission is also provided in the area of the countershaft 38, likewise by means of a toothed belt or the like.

  • the inclination of the suction box 10a and preferably also the braking device 10b are adjustable. In the example shown in FIG. 6, the suction box 10a and the braking device 10b are set in such a way that the distance from the belt arrangement 7 in the transport direction is reduced.
  • the suction plate of the suction box 10a forms a stationary element with respect to the circumferential suction belts forming the braking members 35, by means of which the rear ends of the bow are held up when their front ends have already run into the pulling device 8, which results in a desired stretching of the sheet material.
  • the entire holding device 10 is adjustable in the conveying direction depending on the format.
  • the braking device including braking members and drive motor is received and on which, as can best be seen from FIG. 6, the suction box 10a is pivotally received by means of a lockable pivot bearing 43.

  • the carriage 42 On the other longitudinal spar of the frame 46, the carriage 42 is supported by rollers 47. This makes it possible not only to adjust the carriage 42 and, accordingly, the entire holding device 10 in and against the conveying direction, but also to pivot the guide bar 45 as a whole in order to make the belt arrangement 7 easily accessible, for example in the case of a stopper.
  • the lifting device 11 is adjustable together with the braking device 10b.
  • the lifting device 11 can also be received on the carriage 42.
  • the lifting device 11 is mounted on the frame 46 of the belt arrangement 7 and is connected to the carriage 42 by means of connecting elements, for example in the form of an articulated rod 48.
  • lateral threaded spindles 49 are provided, which can be operated either by motor or, as can be seen from FIG. 5, by means of a shaft provided with a handwheel 50.
  • the longitudinal shaft 34, from which the drive of the lifting device 11 adjustable with the carriage 42 is derived, is, as FIG. 7 further shows, expediently designed as a polygonal shaft on which the lifting device 11 assigned drive element 51 is slidably received. For this purpose, this can be mounted on a bearing lug attached to the displaceable frame.
  • the lifting device 11 on which FIGS. 2 and 6 and 7 are based consists of cam disks 53 which are received on a shaft 52 which can be driven by the longitudinal shaft 34 and which are arranged between the belts of the belt arrangement 7 which acts as a towing device.
  • the cam disks 53 have such a diameter outside of their cam that the bands of the band arrangement 7 are not exceeded. Only when the cam 52a comes up does it run over the surface of the belt, as a result of which the sheet going over it has a clumsy effect.
  • the shaft 52 passes through longitudinal slots 54 of the frame of the belt arrangement 7, which enables the desired adjustability.
  • the cam disks 52 are driven so that their circumference rolls on the sheet at approximately sheet speed.
  • the circumferential speed of the cam disks 53 is accordingly in the region of the cam 53a which is active for ratcheting up about the increased transport speed of the belts of the belt arrangement 7.
  • other high clogging elements for example in the form of swiveling cleats, could of course also be used.
  • blowing nozzles of the type indicated at 55 in FIG. These can, as indicated in FIG. 2 by dashed lines, be arranged pivotably and cooperate with an aperture 56 in such a way that an air jet only in the state not covered by the aperture 56 is exercised on the bow above.
  • Such an arrangement has the advantage that the blowing nozzles 55 can be permanently supplied with blowing air.
