Definitions
- the invention relates to a sheet feeder with a height-adjustable sheet stacking device containing the sheets to be printed in a rotary printing press.
- a sheet feeder of this type is known from DE-B-17 86 545.
- DE-B-1 013 156 shows a device in which sheets can be transferred in batches from a supply stack to an inclined stack. Sheet pack transfer belt systems and a slide are used for this.
- GB-A-2 012 731 also shows a sheet transfer device with which individual sheets can be transferred from a first stack to a second stack, the sheets also being turned during the transfer.
- the first-mentioned device is complex and can only be used if there is a sufficient height difference which is bridged by the slide. With the second device, the sheets are forced to turn, which is often not desirable.
- the single sheet transport requires a considerable amount of time.
- waste paper packs had to be placed by hand on the sheet stack containing the good sheets, if e.g. Good sheets should be saved for printing or when so-called stoppers occur.
- the invention has for its object to provide a sheet feeder in which an automatic transfer of waste sheets to the sheet stack containing the sheets to be printed is possible.
- a second sheet stacking device for storing a waste sheet stack parallel to the edge is arranged, that at least one separating tongue which can be inserted into the waste sheet stack between two waste sheet sheets is provided for dividing the waste sheet stack for the purpose of transferring a waste sheet stack to the sheet stack, and in that can be pulled or pushed onto the sheet stack by the waste sheet transport means of the waste sheet packs.
- An advantage of the invention lies in the possibility of individually controlling the waste sheet transfer by a central control unit, for example by a computer, depending on various operating conditions.
- a central control unit for example by a computer
- the printing costs can be kept low, since automatic and timely transfer of waste sheets is possible, so that these are available for the setup process of the machine instead of unprinted paper.
- stoppers when printing interruptions occur, e.g. after so-called stoppers, the material costs are reduced, since the required number of waste sheets is also available in such cases.
- pressure differences occur, which can originate from the inking unit and / or from the dampening unit, which can be caught by means of waste sheets, and after the waste sheets have been processed, the printing of the good sheets is continued without machine interruption.
- the time-consuming laying on of the waste paper messengers can thus be completely dispensed with during the machine standstill, so that at least one person of the operating team is available for other work during this time.
- the waste sheet stack By controlling the waste sheet stack to the level of the good sheet stack, the number of waste sheets to be transferred in one pack can be influenced, at least in the order of magnitude, in an advantageous manner.
- the use of a blower makes the introduction of the sheet gripper for removing a waste sheet pack much easier.
- FIG. 1 schematically shows a sheet stacking device 1 of a sheet feeder that contains the sheets to be printed in a rotary printing machine.
- a waste paper stacking device 2 is arranged on one of the three accessible sides of the sheet stacking device 1, preferably laterally, parallel to the sheet stacking device 1.
- the stack of good sheets 3 is raised by means of chains 5 and 6, which can be driven by a drive (not shown in detail), so that the uppermost sheet of the stack of good sheets 3 is each in a position which does not supply it to one shown feed table allowed.
- a drive not shown in detail
- a waste sheet pack 4a is to be transferred from the waste sheet stack 4 to the good sheet stack 3 for the proofing or for preparatory work on a printing press or when functional errors occur during production, for example by so-called stoppers, in order to save good sheets, the waste sheet stack 4 is to be transferred to the top edge waste sheet packs 4a raised to the level of the good sheet stack 3 by a sheet gripper 9, which can be designed, for example, as a tong gripper and whose lower part 9a serves as a separating tongue, and by swiveling the sheet gripper 9 by suitable drive means (not shown in FIG. 1), two transport rollers 10 and 11, fed through which the waste sheet pack is grasped and pushed completely over the stack of good sheets 3. After the waste sheet pack 4a has been transferred to the good sheet stack 3, the sheet gripper 9 can be moved back again.
- the control of the waste sheet transfer is preferably by a central control unit 12 which, for. B. can consist of a microprocessor performed.
- Fig. 2 shows a block diagram of the control circuit.
- the control unit 12 controls a stack motor 13 for driving the chains 5, 6 of the sheet stacking device 1 and a stack motor 14 for driving the chains 7, 8 of the waste paper stacking device 2.
- a blower motor 15 is connected to the control unit 12 (FIGS. 2 and 4), with the aid of which air is blown against a side of the waste sheet stack 4 by means of a suitable blower, so that the introduction of the sheet gripper is facilitated.
- a gripper drive device 16 which is not shown in detail in FIG. 1, controls the sheet gripper 9 in a timely and path-oriented manner.
- a printing and / or sheet transport monitoring circuit 17 can be used to detect the operating conditions or operating states by means of which the supply of waste sheets is necessary.
- the control unit 12 can also be addressed via a control panel 18, which is equipped with an appropriate keyboard (not shown / equipped in detail), so that the introduction of a waste sheet transfer is possible manually.
- the control unit 12 becomes a transport roller drive motor 19 for the transport rollers 10 and 11 controlled.
- Fig. 3 shows a second embodiment of a waste sheet transport device.
- the sheet gripper 9 is fastened to a carriage 20 which can be moved along a guide rail 21 over the sheet stack 3.
- a threaded spindle 22 is used, which can be rotated in both directions by means of a motor 23.
- the carriage 20 and thus the sheet gripper 9, which detects a waste sheet pack 4a can be moved over the sheet stack 3, i.e. H. from right to left and then from left to right.
- the transport rollers 10 and 11 used in FIG. 1 are in the embodiment according to FIG . 3 not absolutely necessary, since the entire transfer process can be carried out by the sheet gripper 9 alone.
- the motor 23 used here for driving the spindle 22 can also be controlled by a central control unit, as was described in connection with the exemplary embodiment 1 in FIG. 2.
- the carriage 20 with the bow gripper 9 can be moved past the side of the suction head lock 25 by a suitable arrangement of the spindle 22 in an existing free passage.
- the sheet gripper 9 is lifted by a lifting means, for. B. by an attached to a controllable telescopic arm electromagnet 24, on an excessive path back to the waste sheet stack 4, so that touching the top sheet on the sheet stack 3 is avoided during the return movement of the sheet gripper 9.
- FIG. 4 shows a further exemplary embodiment in which a waste sheet pack 4a can be pushed onto the stack of good sheets 3 by a sheet gripper 26 designed as a slide, the lower part 26a of which acts as a separating tongue.
- the sheet gripper 26 is fastened to a slide 27 which can be moved from left to right and vice versa on a guide rail 28.
- a threaded spindle 29 is used, which can be driven by a motor 30 in both directions.
- the sheet gripper 26 can be returned to the right starting position by an appropriate device, for example by fastening it to a telescopic arm, in an excessive way after the waste sheet pack 4a has been dispensed .
- a hold-down device 34 which can be displaced in terms of height on a side wall and which, after gripping the waste sheet pack 4a to be transferred, can be pushed in or swung in below the sheet gripper 26 and thus holds the remaining waste sheets on the waste sheet stack 4.
- This arrangement with the hold-down 34 can also be used in principle in all of the exemplary embodiments.
- the sheet gripper 26 pushes a waste sheet pack 4a to be transferred to the left, so that it reaches the area of influence of two conveyor belts 32 and 33, in the place of which conventional transport rollers can be used.
- the complete transfer of the waste sheet pack 4a to the good sheet stack 3 is then carried out with the aid of the conveyor belts 32 and 33.
- the stack of waste sheets 4 can be slightly inclined to facilitate the handing over of a waste sheet pack 4a, which is indicated by the inclined plane 35. This is easily possible with the help of chains 7 and 8. This reduces the coefficient of friction to be overcome when handing over a waste sheet pack.
- the spindle 29 over the entire waste sheet stack 4, d. H. extends to the left side wall of the waste paper stack 4. In this case, the use of transport rollers or conveyor belts can be dispensed with, in particular when the waste sheet stack 4 is brought into the inclined plane 35.
- patchers On both sides of the sheet stack 3 shown in FIGS. 1, 3 and 4 and, if desired, also front and rear are so-called patchers, e.g. B. in the form of alignment plates, which are connected to a vibrator, by means of which the upper sheet ees sheet stack 3 can be aligned.
- patchers e.g. B. in the form of alignment plates, which are connected to a vibrator, by means of which the upper sheet ees sheet stack 3 can be aligned.
- a compensation plate 36 with a vibrator 37 is only indicated schematically in FIG. 1.
