Definitions
- the invention relates to a feeder of a sheet processing machine with a blowing device according to the preamble of claim 1.
- Feeders are used on sheet-fed printing machines in order to separate sheets of different material that have been prepared on stacks and feed them to the printing machine.
- the sheets are separated and fed by so-called sheet separators.
- blowing devices are often provided by which the sheets can be subjected to blowing air from one side of the stack.
- a feeder of a sheet-fed printing press is known from DE 102017210247 A1, with blower elements, so-called side blowers, being provided on the longitudinal sides of the stack for pre-loosening the sheets.
- the side blowers can be adjusted in the longitudinal direction on a rail that extends in the sheet transport direction, e.g. B. by engagement with a threaded rod which can be driven in rotation by means of a servomotor hidden in the legs of the investor.
- US 2017/0174453 A1 relates to a sheet feeder and discloses side stops with blower air openings integrated into them for lateral loading of the stack of sheets. By operating side stops and a back stop, the sides of the stack and the back of the stack are aligned. Instead of being operated manually, it can also be actuated by a robot or a corresponding device.
- JP S63-315434 A relates to a device for separating adhesive sheets on a stack of sheets, with air being able to be blown in the direction of the stack from lateral positioning claws
- blown air is guided through a length-adjustable channel that passes under the stack and into a side stop, from which sheets in a stack can be blown from the side.
- US 2009/0014948 A1 relates to a sheet output chute of a printer, copier or the like, with the separation of the sheets being assisted by blowing the stack of sheets only below the topmost layer, by causing a negative force on the upper side of the sheets.
- JP H04-361929 A relates to a device for separating stacks of plates.
- the object of the invention is to create an improved feeder for a sheet processing machine with a blowing device.
- blowing device can be adjusted or at least preset in a simple and/or reliable manner, in particular in a defined and reproducible manner.
- a setting, or at least a presetting, for adjusting the lateral position of blow heads when the sheet format changes with a changed width and/or length can take place without manual intervention.
- the side blowers with format change can be adjusted or tracked without z. B. to collide with a likewise and/or simultaneously movable sheet separator and, if necessary, its device carrier or to avoid it by deformation.
- Coupling can basically be a purely control-technical coupling of the two coupled movements causing drive means, the two actuating movements are specified in a fixed, but possibly changeable relationship to each other, or in a z. B. more robust less susceptible to failure and / or electrotechnically less complex solution by mechanical coupling. In both cases, it can be advantageous if the respective movement takes place along a fixed or mechanically predetermined movement path.
- the side blowers in addition to being relocatable, also have a movable nozzle head, it may be possible and/or useful, after a defined and/or forced adjustment of the side blower position, to carry out a fine adjustment by appropriately adapting the course of flexible hose lines. In this case, however, due to the low need for adjustment, no hose lines that are flexible in length to the nozzle head are required.
- a blowing device is provided, through which sheets of a stack received in the feeder can be subjected to blowing air on a side flank, i.e. on a side of the stack running vertically and parallel to the transport direction, in the area of their sheet edge, with the blowing device preferably having at least one movement component in the transport direction is relocatably stored in or on the feeder.
- the blowing device is mounted in or on the feeder so that it can be displaced along a mechanically predetermined movement path with at least one movement component transverse to the transport direction.
- a drive means is provided, by means of which the displacement of the blower element can be brought about directly or indirectly.
- Adjusting means of the feeder preferably comprise a control-related or mechanical coupling such that the blowing device is adjusted transversely to the transport direction and adjusted in the transport direction in a positively coupled manner in a defined manner.
- a drive means is provided, by which the displacement of the blower element with at least the movement component transverse to the transport direction can be effected directly or indirectly, and a different drive means, by which the displacement of the blower device with at least the movement component in the transport direction, can be used for coupling control means be provided, which preset the drive means causing the two adjusting movements in a fixed relationship to one another.
- the blowing device and a stop element whose position can be adjusted transversely to the transport direction are mechanically coupled to one another in the feeder in such a way that the setting of the stop element and the displacement of the blowing device are forcibly coupled by the same actuator.
- it is a stop element that is spatially spaced apart from the blowing element in the transport direction and/or is mounted independently of the blowing element of the blowing device on or in the feeder.
- B. is a maximum of 200 mm behind the front edge of the stack - and possibly also includes a blowing element that can be moved together with this - and the single or foremost blowing element of the blowing device is further away from the front edge of the paper than the stop element.
- 1 shows a schematic side view of a feeder and a sheet feeder of a sheet-fed printing press arranged upstream of a printing unit; 2 shows an oblique view of an upper side of a stack of a first sheet format with sheet separators, side stops and blowing devices;
- FIG. 3 shows a plan view of the arrangement from FIG. 2 for the case of a first sheet format
- FIG. 4 shows a plan view of the arrangement from FIG. 2 for the case of a second sheet format which is considerably smaller than the first sheet format.
- FIG. 1 shows an example of a detail of a machine that treats or processes sheets 06 and is preferably embodied as a sheet-fed printing press. In principle, however, it can also be processed by another machine that treats or processes sheets 06, e.g. B. a punch, cutting, painting or other machine with the requirement of an input-side sheet separation can be formed.

- a stack 09 for example a stack of sheets 09, is placed on a stacking table 10 in feeder 01.
- the stacking table 10 can be adjusted in height with the aid of a lifting device 11 in order to raise the top sheet 06 of the stack of sheets 09 to a fixed or only slightly variable height, regardless of the number of sheets 06 in the stack 09, so that it is suitable for transferring the sheets 06 to the belt table 02 keep.
- a lifting device 11 in order to raise the top sheet 06 of the stack of sheets 09 to a fixed or only slightly variable height, regardless of the number of sheets 06 in the stack 09, so that it is suitable for transferring the sheets 06 to the belt table 02 keep.
- stacking table 10 could also contain a pallet on which stack 09 was transported to stacking table 10 and placed on it, and the height of which is not known, so that the position of lifting device 11 does not indicate the height of stack 09 or the number of sheets 06 contained in the stack 09 can be closed.
- a front stop 16 defines a vertical plane in which the front edges of the sheets 06 of the sheet stack 09 are positioned.
- a sheet flap 17 can be pivoted counterclockwise about a flap shaft 18 between the position shown in Fig. 1, in which the front stop 16 extends straight upwards, into a substantially approximately horizontal position, in which it supports the transport of the sheets 06 to the downstream belt table 02.
- the feeder 01 comprises various tools, combined here in a sheet separator 14, for dividing the stack 09 into individual sheets 06 and for transporting the sheets 06 away to the printing units 04 and possibly other units 04 of the sheet-fed printing press.
- These tools include, on the one hand, a plurality of so-called suction cups 12, in particular handling tools 12 embodied as separating or lifting suction cups 12, in particular lifting tools 12, which are arranged above a rear edge 05 of the stack 09 in the transport direction T of the sheets 06 and can be moved essentially in the vertical direction are.
- the separating suckers 12 each comprise a suction cup made of flexible plastic which is open at the bottom towards the stack 09 and is connected at its upper end to a common vacuum source. The negative pressure must be sufficient to allow the suction cups to adhere securely to the sheet 06 to be lifted from the stack 09, but it must not be so strong that it draws the sheet 06 into the suction cup and deforms it as a result.
- each sucker separator 12 can be movable relative to the sheet separator 14 with the aid of its own drive, in particular a linear actuator; a common frame in which all sucker separators 12 are held is preferably movable relative to the sheet separator 14 with the aid of a fast, powerful main actuator , in order to suck up the sheet 06 from the stack 09 and lift it along the rear edge 05 of the sheet 06, and to even out any unevenness on the upper side of the stack 09 and to ensure simultaneous contact of all suction separators 12 with the sheet 06 to be lifted, the suction separators 12 are Adjustable relative to the frame by means of auxiliary actuators, the latter of which can be slower and have a smaller stroke than the main actuator.
- auxiliary actuators the latter of which can be slower and have a smaller stroke than the main actuator.
- a further tool of sheet separator 14 can be a tool 15 embodied as a feeler foot 15, which can be provided between a holding position shown in Fig. 1, pressing along the edge 05 onto the stack 09, and a holding position that is raised relative to the holding position and opposite to the transport direction T behind the rear edge 05 of the sheet 06 offset rest position is movable.
- the tool 15, for example the feeler foot 15, is placed in the holding position when the top sheet 06 of the stack 09 has been lifted by the suction separators 12 along the rear edge 05, in order to prevent the underlying sheets 06 of the stack 09 from being whirled up when a blowing device 19 arranged behind the rear edge 05 at the level of the top of the stack 09 blows air into an open gap 07 between the lifted sheet 06 and the rest of the stack 09.
- suckers 13, in particular designed as transport suckers 13, handling tools 13, in particular transport tools 13, are provided which have a predominantly vertical movement in or against the Execute the transport direction T of the sheets 06.
- the transport suckers 13 have flexible suction bells, which, after the suction separators 12 have been raised, are subjected to a vacuum in order to pull the lifted sheet 06 towards them. At the same time, vacuum is no longer applied to suction separators 12, so that they release sheet 06.
- blower device 19 lifts sheet 06 over its entire surface from stack 09 and forms an air cushion under sheet 06, on which sheet 06, driven by the horizontal movement of transport suckers 13, over which the the horizontal pivoted sheet flap 17 is pushed away onto the belt table 02.
- Aforesaid sucker 12; 13 can alternatively also be designed as working according to the Bernoulli principle, in short as a so-called Bernoulli suction device.
- the above applies accordingly with the difference that they are connected to an overpressure source and are or are operated with air that is under overpressure compared to the environment.
- the belt table 02 downstream of the feeder 01 is designed as a suction belt table 02 in the exemplary embodiment. It preferably comprises two rollers 20; 21, for example a drive roller 20 and a deflection roller 21. Between the two rollers 20; 21 extends a one-part or multi-part table plate 22. The table plate 22 forms the multiple perforated upper side of a suction box 23.
- the drive roller 20 and the deflection roller 21 are wrapped by at least one conveyor belt 24 which, like the table plate 22 over which it extends, is perforated many times, so that it is not sucked onto the table plate 22, but a sheet 06 is sucked onto the conveyor belt 24.
- the circumferential speed of the conveyor belt 24 is generally lower than the ratio of the edge length of the sheets 06 to the cycle time of the sheet separator 14, so that when the transport suckers 13 begin to feed a new sheet 06 via the sheet flap 17 slide, the previous sheet 06 has not yet completely passed them.
- a shingled flow of sheets 06 is thus formed on the conveyor belt 24, in which the number of sheets 06 overlapping one another is variable depending on the circulation speed, edge length and cycle time.
- the sheet feeder 03 to which the sheets 06 are conveyed by the circulating conveyor belt 24, comprises a feed table 26 and, on a rear edge of the feed table 26 in the transport direction T of the sheets 06, stops 27, which are shown in FIG
- the stop position blocking the conveying path of the sheets 06 can be lowered in order to clear the path for a sheet 06 resting against the stops 27 to the following printing unit 04, of which a transfer drum 29, an impression cylinder 30 and a rubber blanket cylinder 31 are shown in Fig. 1.
