Definitions

the invention relates to a device for aligning sheet stacks in the feeder of sheet-processing machines according to the preamble of claim 1 and a method for aligning sheet stacks according to the preamble of claim 8.
the DE 196 27 241 C2 describes a device for forming a sheet pile in the boom of a sheet-fed press.
the alignment is done with the aid of vibrating plates, which are connected to vibration exciters.
the vibration exciter vibrates independently of the Auslegetakt.
the DE 42 20 074 A1 shows a device for rattling a stack. For Geradrichen while a bumper is used, which points in the direction of the stack and has at its one end a bumper.
the two devices mentioned have in common that the shock or shaking movement is purely translational.
a device with a swinging movement of an alignment plate is in the DE 198 52 365 C2 described.
a side fence for aligning sheets on delivery stacks in outriggers of printing presses has an alignment plate.
the alignment plate is mounted in a pivot bearing.
the pivot bearing acts as a pivot around which the alignment plate is rotated at a small angle. At its maximum angle of rotation, the alignment plate abuts the delivery stack and aligns it. Subsequently, the alignment plate is pivoted back to its original position.
the vibration excitation of the alignment plate happens via a pneumatic drive.
the object of the present invention is therefore to automatically align the sheet stack in the feeder during a continuous stacking upward movement. According to the invention, this object is achieved by a device for aligning sheet stacks with the characterizing features of claim 1 and by a method having the characterizing features of claim 8.
the device according to the invention allows sheet stacks in the feeder both exactly, d. H. accurate to the edge, as well as gentle, d. H. without damaging the arch, align.
the careful alignment is achieved in that the alignment plate of the device for aligning sheet stacks in the feeder of sheet-processing machines describes approximately a circular path.
the alignment plate remains parallel to the side surface of the investor sheet stack and the top edge of the alignment plate is aligned parallel to the top edge of the investor sheet stack.
a motion converter Between a motor drive and the alignment plate is a motion converter. This transforms the provided on the motor drive rotational movement and forces the alignment plate on a movement which describes approximately a circular path.
the motion converter has in an advantageous embodiment, at least one toothed belt pulley, to which the rotational movement of the motor drive is transmitted via a toothed belt.
the rotational movement of the motor drive can also be transmitted either via a circulating toothed belt or else via a plurality of toothed belts.
the toothed belt pulleys are each flanged on a rotatably mounted shaft. At its one end or at both ends, each shaft is fixedly connected, each with a lever in a first pivot point of the respective lever. In a second pivot point of the respective lever, the alignment plate is rotatably supported by means of a respective bolt.
the motion converter still has an element for vertical guidance of the alignment plate.
the device for aligning sheet stacks has a motion converter with two toothed belt pulleys.
the two horizontally spaced levers of the motion converter are arranged exactly parallel to each other to allow a synchronous rotational movement of the two levers and thus an approximately circular movement of the alignment plate.
the vertical guide of the alignment plate is given by their storage in the two pivot points of the lever.
the motor drive of the device for aligning sheet stacks may be, for example, a servomotor or a frequency-controlled three-phase motor.
a respective device for aligning sheet stacks on both sides of the investor ie fixed in the sheet transport direction right and left to the frame of the investor.
the device for aligning sheet stacks is mounted on the investor frame so that the alignment plate is at the height of the top edge of the feeder sheet pile. This ensures that the upper part of the stack of sheets is laterally aligned and the sheets of the sheet processing machine can be accurately fed.
the inventive device with the Approximately circular motion of the alignment plate as opposed to the predominantly translatory motion of prior art alignment plates, prevents interference from the upward movement of the feeder stack with the sideways jogging motion of the alignment plate.
the speed of the alignment plate can be regulated as a function of the machine speed.
the speed adjustment of the alignment plate is automatically made by the machine control.
the movement of the alignment plate also has a horizontal component of movement. This causes an impact movement of the alignment plate and thus the alignment of the sheet stack.
FIG. 1 the basic structure of a sheet punching and embossing machine 100 for punching, breaking and depositing sheets 1 of paper, cardboard and the like is shown.
the punching and embossing machine 100 has a feeder 10, a punching station 2, a breaking station 3 and a boom 4, which are supported and enclosed by a common machine housing 5.
the feeder 10 is a manual non-stop feeder 10 provided with means for introducing a new main stack (in Fig. 1 not shown).
the figure shows a feeder stack 11 located on a pallet 12.
the feeder 10 has a device for moving the feeder stack 11 clocked upwards (in FIG Fig. 1 not shown).
a device 20 is attached, which has an alignment plate 21 for aligning the sheet 1 of the feeder stack 11.
the sheets 1 are separated by a feeder 10 from a feeder pile 11 and fed via a feed table 6 of the sheet punching and embossing machine 100 and by a transport system 7 with gripper carriage 9 in the sheet transport direction T through the various stations 2, 3 and 4 of the punching and Embossing machine 100 pulled through.
the punching station 2 consists of a lower table and an upper table.
the undertable is fixedly mounted in the machine frame and provided with a counter plate to the punching knife.
the upper table is vertically moved back and forth.
the gripper carriage 9 transport the sheet 1 of the punching and embossing station 2 in the subsequent breaking station 3, which is equipped with breakout tools.
the break-out station 3 the unwanted pieces of waste are pushed out of the sheet 1 downwards with the aid of the break-off tools, whereby the waste pieces fall into a container-like carriage inserted below the station.
the boom 4 may also include a pallet on which the individual sheets are stacked in the form of a stack, so that after reaching a certain stack height, the pallets can be moved away with the stacked sheets 1 from the area of the punching and embossing machine 100.
Fig. 2 shows an inventive device for aligning sheet 20. This is attached to the feeder 10.
the sheet aligning device 20 is comprised of a motor drive 22, an alignment plate 21, and a motion converter 27 disposed therebetween.
the motion converter 27 converts the rotational motion of the motor drive 22 and forces the alignment plate 21 to move in an approximately circular manner.
the rotational movement of the motor drive 22 is transmitted via a toothed belt 23 to two toothed belt pulleys 24.
the toothed belt pulleys 24 are each flanged on a shaft 25.
a lever 28 is attached.
the alignment plate 21 is connected to the levers 28.
lever 28 are mounted firmly.
the alignment plate 21 is thus secured by means of a respective bolt 26 on one of four levers 28.
Out Fig. 3 and 4 shows that the alignment plate 21 is aligned parallel to the side surface of the investor sheet stack 11.
Fig. 4 shows that vertically spaced levers 28 are each aligned exactly parallel to each other.
Figure 5 shows the movement of the alignment plate 21 within a cycle of movement.
the different positions of the alignment plate 21 and the two are visible Bolt 26 indicated by dash-dotted lines.
the circular path on which a bolt 26 moves and the circular path on which the alignment plate 21 moves are also indicated.
the operation of the motion converter 27 is clear from this illustration:
the timing belt 23 By the timing belt 23, the two pulleys 24 (in Fig. 5 not drawn) in a rotational movement.
the toothed belt pulleys 24 are firmly flanged on the shafts 25.
the levers 28 are rotatably mounted on the shafts 25. Common pivot point of shaft 25, timing pulley 24 and lever 28 is the first pivot point D1.
the alignment plate 21 is connected via bolts 26 with the levers 28 and rotatably mounted in the bolt 26 in a second pivot point D2.
First pivot point D1 and second pivot point D2 are spaced apart. The size of the distance determines the circular motion, which is imposed on the alignment plate 21.
