Definitions

  • the invention relates to a sheet feeder with a stack associated with stationary front stops, with holders accommodated on a longitudinal guide running transversely to the transport direction for side stops adjustable on the stack side edges, and preferably side blowers, with a longitudinal guide taken in a transport direction, on the latter depending on the stack rear edge definable suction head, with a conveyor table which receives the sheets lifted off the stack in the form of a shingled stream, on which at least one row of pressure rollers interacting with surrounding belts is received, the distance of which from the front marks provided at the front end of the conveyor table depending on the sheets format length is adjustable and with at least one provided in the area of the conveyor table, recorded on a longitudinal guide extending transversely to the transport direction, adjustable to the sheet format width.
  • the settings of the suction head, the side stops, the pressure rollers and the side mark necessary when changing the format must be carried out manually. This proves to be very cumbersome and time consuming. In addition, this requires appropriate accessibility to the units to be adjusted.
  • the manual adjustment of the pressure rollers assigned to the belts of the conveyor table can be particularly disadvantageous, since these are distributed over the entire width of the conveyor table and therefore cannot be reached from a common side, so that several adjustment processes are carried out from both sides of the conveyor table to set all the pressure rollers.
  • the front row of the pressure rollers must be set so that the sheets passing over the conveying table are out of engagement with the pressure rollers when they reach the front mark in order to prevent the sheets from being compressed.
  • the pressure rollers should not be set too far back to ensure reliable transport of the sheets to the front marks. This requires a high degree of accuracy in the setting of the pressure rollers, which in the case of manual setting requires multiple corrections. Overall, therefore, in the known arrangements with manual format setting, there are high overall set-up times.
  • At least the pressure rollers and / or the suction head and / or the holder of the side stops and / or the side mark or marks are adjustable by means of a respectively assigned servomotor and that this servomotor or these servomotors are adjusted by means of a computer can be set depending on the format values that can be entered in these.
  • the automatic setting of the pressure rollers advantageously results in a very great simplification of the format setting. Since this involves several units, the machine setting of the pressure rollers together can already reduce the set-up times considerably.
  • the mechanical setting advantageously also results in a high level of accuracy, so that compression of the sheets running against the front marks is avoided and at the same time reliable transport is ensured, which has an overall advantageous effect on avoiding operational malfunctions and achieving high quality.
  • the mechanical adjustment of the pressure rollers already makes work much easier, the mechanical format adjustment of all units to be adjusted when changing the format results in a further increase in user-friendliness and a further reduction in set-up times. If in addition to the pressure rollers, the suction head, the holder assigned to the side stops and the side marks are set mechanically, this advantageously results in a practically fully mechanized format setting, any manual setting being omitted.
  • the servomotors can be designed as drive motors of a respectively assigned threaded spindle which is supported in the axial direction on the frame side and which is in threaded engagement with the respective unit or units to be adjusted. This measure results in a simple and clear structure as well as a robust and maintenance-friendly construction.
  • the pressure rollers arranged next to one another are each received on a common carrier, the pressure roller carriers located one behind the other being in threaded engagement with sections having gradients which are stepped from front to rear with respect to one another of a threaded spindle serving all pressure roller carriers.
  • the use of a carrier which extends over the machine width to accommodate pressure rollers arranged next to one another ensures that practically one spindle with an assigned servomotor is sufficient to operate all pressure rollers, which simplifies the construction and reduces the effort required.
  • the use of a stepped lead screw ensures that the rear pressure rollers are adjusted to a lesser extent than the front pressure rollers, which is advantageous in ensuring reliable sheet transport affects every setting.
  • the threaded spindle assigned to the side stops is provided with opposing threads assigned to the two side stops. This allows the side stops provided on both sides to be adjusted together symmetrically to the longitudinal axis of the feeder.
  • a further expedient measure consists in that the threaded spindle assigned to the side stops and the associated longitudinal guide are accommodated on a frame which is displaceably mounted in the feeder frame between two end positions transversely to the transport direction and preferably by means of a remote-controlled actuator in the off-center end position opposite the side of the activated side mark can be brought.
  • the side stops can preferably be adjusted by hand with the side blowers on the associated holder which interacts with the associated threaded spindle and is guided on the associated longitudinal guide be included.
  • This measure enables manual adjustment of the side stops and side blowers, which can be desirable in particular in the event of irregularities in the area of the stack side edges.
  • the drive device can expediently have a double bevel gear transmission, which is accommodated in a housing, which is preferably displaceably arranged by means of a remote-controlled actuator, with a shaft driven by the motor accommodated on the housing and two drive shafts aligned with the associated threaded spindle.
  • the displaceability of the housing accommodating a countershaft and the servomotor enables simple design of the couplings on both sides.
  • the bevel gear used advantageously results in a reversal of the direction of rotation, so that synchronous threaded spindles can be used on both sides and a reversal of the servomotor is not required.
  • a further advantageous measure can consist in the fact that the side marks in an associated, transverse to the transport direction, in the area of the för dertician provided channel are arranged, which is covered by means of an extendable, approximately at the level of the conveyor table, with its ends on the one hand side mark side and on the other hand table side attached cover.
  • the pull-out cover provides a precise arch support in the area of the side marks.
  • the threaded spindle assigned to the suction head can be mounted on the longitudinal guide receiving the suction head and can engage in a threaded sleeve of the suction head which projects over the longitudinal guide.
  • FIG. 1 shows a stack 1 which is received on a stacking table 2.
  • the stacking table 2 is suspended on lifting chains 3, which are guided by chain wheels 5 which can be driven step by step by means of a motor 4.
  • the height of the stack is set as a function of the height of the front edge of the stack resting against stationary front stops 6.
  • a mechanical button 7 is provided, which intermittently scans the upper side of the front edge of the stack approximately in the area of the feeder center longitudinal plane, which, via a linkage, has two switches 8 opposite one another, forming a two-point control acts via which the motor 4 can be activated or passivated.
  • the intermittent stacking engagement of the button 7 is accomplished by two cam disks 9 which produce a lifting movement or a pivoting movement and are driven in time with the sheet feeder.
  • the button 7 is accordingly attached to a rocker arm 10 which is pivotally mounted on a lifting rod 11, the lower end of which cooperates with the switches 8.
  • a suction head 12 is arranged, which is provided with lifting suction devices 13 for lifting the top sheet in each case and drag suction devices 14 for the forward transport of the respectively lifted sheet, as well as with a presser foot 15 placed on the trailing edge of the sheet at every cycle.
  • the suction head 12 is displaceably guided on a horizontally oriented longitudinal guide 16 which runs parallel to the sheet transport direction and is formed by a square rail fastened to the feeder frame and can therefore be adjusted each time the format is changed so that its presser foot 15 precisely scans the trailing edge of the stack.
  • the suction head 12 is clamped to the longitudinal guide 16 by a tensioning device 20 indicated in FIG.
  • the clamping device 20 can simply be designed as a pneumatically actuated cylinder-piston unit.
  • the working height of the suction head 12 can be adjusted according to the height of the rear edge of the stack, which can differ from the height of the front edge of the stack.
  • the longitudinal guide 16 assigned to the suction head 12 together with the associated threaded spindle 18 with the servomotor 17 is accommodated on threaded spindles 21 which are accommodated perpendicular to the sheet transport plane on the feeder frame and which can be driven via a respectively assigned bevel gear countershaft 22.
  • the two bevel gear countershaft 22 are connected to one another via a shaft 23 which is parallel to the longitudinal guide and which is connected via an associated one Actuator 24 can be driven.
  • the control of the servomotor 24 takes place via the presser foot 15 acting as a button, which is received on two parallel rockers 25, one of which interacts with two opposing switches 26 forming a two-point control, by means of which the servomotor 24 can be activated or passivated.
  • the stack 1 lies with its front edge against the stationary front stops 6 formed by strips attached to the feeder frame.
  • the side edges of the stack 1 are located between side stops 27 which practically form a paper guide.
  • so-called side blowers 28 can be located which are connected to a blown air source.
  • the position of the stack side edges changes with the format, as can be seen from FIG. 2 by comparing the solid and dashed outline edges of the stack 1 or 1a.
  • the side stops 27 and side blowers 28, like the suction head 12, can therefore be adjusted to the respective sheet format.
  • a longitudinal guide 29 running transversely to the sheet transport direction is provided, on which two holders 30 receiving the side stops 27 and side blowers 28 on both sides are slidably mounted.
  • a threaded spindle 31 which runs parallel to the associated longitudinal guide, is used to adjust the holder 30, which engages with opposite threaded sections, each with a holder 30, and can be driven by means of a servomotor 32.
  • a servomotor 32 To achieve a fine adjustment of the side stops 27 and side blowers 28, these are connected to the respectively assigned holder 30 via a manually operable adjusting screw 33.
  • the threaded spindle 31 and parallel longitudinal guide 29 are combined by side end plates 34 to form a frame 35.
  • the end shields 34 are slidably mounted in the feeder frame with guide pins 36 which run parallel to the longitudinal guide, that is to say transversely to the transport direction, so that the entire frame 35, as can further be seen in FIG. 2, can be brought from a right-hand to a left-hand end position and vice versa.
  • a remotely controllable actuator 37 is provided, which in the exemplary embodiment shown is designed as a pneumatically actuated cylinder-piston unit.
  • the lateral adjustability of the frame 35 enables the stack 1 to be positioned so far to the left or right with respect to the longitudinal plane of the feeder that the sheets can be placed exactly in the middle before being transferred to a processing machine by means of side drawing marks 39 arranged in the region of a conveyor table 38 arranged downstream of the stack receiving area .
  • the sheet lifted by the lifting suction devices 13 and transferred to the drag suction devices 14 is passed through these to transport rollers 40 arranged in front of the front stops 6 and passes via these onto the conveyor table 38, which is normally slightly inclined forward. This is covered by transport belts 41 distributed over its width , which are assigned pressure rollers 42. At the front end of the conveying table 38, pivotable front marks 43 are arranged, on which the leading edge of the sheet is aligned.
  • the pressure rollers 42 must be in every format change can be set so that the sheet lying on the front marks 43 is just out of engagement with the front row of pressure rollers and is therefore not compressed.
  • the pressure rollers 42 arranged next to one another are received on a common support 44 formed by a rail running across the entire width of the machine and are jointly adjustable by means of this.
  • a threaded spindle 46 can be driven by means of a servomotor 45, which is axially supported on the feeder frame and is in engagement with the carrier 44 or the carriers 44 assigned to the rows of pressure roller rows, provided that the rear pressure rollers are also adjusted, as in the exemplary embodiment shown should be.
  • the rear rows of pressure rollers are each received on a common carrier 44 which is in engagement with the threaded spindle 46, as can be clearly seen in FIG.
  • the threaded spindle 46 has threaded sections associated with the brackets 44 arranged one behind the other with a stepped pitch.
  • the slope of the rear threaded section is smaller than the slope of the front threaded section, which leads to a smaller adjustment path in the area of the rear pressure rollers 42 than in the area of the front pressure rollers. This ensures that the rear pressure rollers are approximately in the area between the front pressure rollers and the transport rollers 40 with each adjustment of the front pressure rollers 42, which results in a reliable sheet transport.
  • the side drawing marks 39 Upstream from the front marks 43 there are two in the region of the conveyor table 38 with respect to the feeder center longitudinal plane mutually opposite side drawing marks 39 are provided, one of which is activated for the lateral alignment of the sheets.
  • the side pulling marks 39 come into engagement with the lateral sheet edge and, like the side stops 27, can accordingly be adjusted to the sheet format width.
  • the side drawing marks 39 are received on a longitudinal guide 47, which is formed by a rail running across the machine width and runs transversely to the sheet transport direction.
  • a threaded spindle 48 is assigned to each side mark 39.
  • the two threaded spindles 48 are arranged in alignment in the axial direction with a central spacing next to one another.
  • the drive unit 49 has a gear box 51 which is displaceably received on the longitudinal guide 47 and to which the servomotor 50 is fastened and in which a double bevel gear 52 which can be driven by means of the servomotor 50 and has two output shafts is arranged.
  • the driven shaft of the double bevel gear 52 running in the sheet transport direction is fixedly connected to the actuator 50 attached to the gear box 51.
  • the two output shafts 53 of the double bevel gear 52 are aligned with the two threaded spindles 48 and each provided with a coupling element 54 which can be brought into engagement with an opposite coupling element 55 fastened on the threaded spindle side.
  • a remote-controlled actuator 56 is provided for moving the gear box 51 simply designed as a pneumatically actuated cylinder-piston unit. Instead of shifting the drive device, it would also be possible to provide only an electrical or pneumatic activation of the left or right shaft coupling.
  • the side pulling marks 39 are located in a channel 57 of the conveyor table 38 lying in front of the front deflection rollers of the conveyor belts 41.
  • the latter can be covered by means of covers 58 that can be covered with bellows, which cover on the one hand on the inwardly facing edge of the housing a side pull mark 39 and, on the other hand, are fastened to the outwardly facing edge of a centrally arranged cover plate 59 which overlaps the displaceable gear box 51.
  • the actuators 4 and 24 which can be activated as a function of the height of the front or rear edge of the stack can, as already mentioned above, be activated or passivated by means of the associated switches 8 and 26.
  • the servomotors provided for setting the format here the servomotors 17, 32, 45, 50 can, as is also indicated in FIG. 1, be controlled by means of a computer 60, into which the respective sheet format can be entered in the form of a length and width dimension.
  • the computer 60 is provided with a keyboard 61 for preselecting the format and a digital display 62 for displaying the entered format length and format width, and is connected to the servomotors 17, 32, 45 and 50 to be controlled by signal lines 63.
  • the length and width of the format sheet are entered on a keyboard.
  • the units provided with servomotors By pressing a start button, the units provided with servomotors, such as the suction head and side stops, etc., move to the entered format. Often required, certain format dimensions can be saved in the computer and are then assigned a code no. available at any time. The individual units such as the suction head and side stops etc. then move to the positions defined in the memory.
  • Another possibility for input is that all the formats are run through in a search run displayed on the digital display 62 and the search run is simply stopped at the desired value in order to enter the desired format.
  • the individual servomotors can be controlled uniformly. Here the control should take place in such a way that the desired position is first approached in an overdrive and then set precisely in a slow gear.
  • the servomotors are accordingly designed as multi-speed motors. From the control value for the suction head 12 (format length) that for the pressure rollers 42 and from the control value for the side stops 27 (format width) that for the side mark 39 can be derived, which simplifie
  • the positioning of the individual units is indicated with solid lines in a comparatively large sheet format and with dashed lines in a relatively small sheet format.
  • the changeover is made simply by entering the new format into the computer 60 by stopping the search at the desired length or width dimension.
  • the set dimension is indicated by the digital display 62 displayed, here 720 length dimension and 1040 width dimension.
