Definitions

  • the invention relates to a sheet depositing device for flexible flat material, in particular Paper, with at least one deflection wheel, which is at least one essentially has tangentially arranged receiving slot, a sheet feeder, which in the at least one receiving slot opens when it is in a receiving position is located and a sheet deposit stop in a position opposite the receiving position Area of the deflection wheel, this in a recess of the sheet deposit stop runs and the latter in a sheet deposit position at least on one side of a Recording slot is.
  • Such a sheet depositing device is known from DE 23 09 075 A1. At this A straight stack is created on the sheet stacker. Often there is Need for an offset in the sheet tray after a certain number of sheets is done in the stack. This can serve, for example, the total number of the leaves easier to grasp. However, this is particularly important if it is ongoing different sheets are printed that belong together. This is often the case with electrophotographic Printing presses the case. Then it is necessary that through a such a shift separates one job from the other.
  • the invention is therefore based on the object of a sheet depositing device at the beginning mentioned type in such a way that an offset in the laid out in a simple manner Stack can be generated.
  • the invention makes it possible with a simple further development, without interruption to create an offset of the sheet deposit at any time. That’s it For example, it is possible to separate one job from the other, even if the jobs are each have a different number of sheets. Furthermore, it is also possible for the invention to be used in a smaller setting area, the storage position of the sheets to regulate in order to correct deviations and thereby related sheets stack neatly on top of each other.
  • the function of the invention is that the flat material in the receiving slots runs and after 90 ° rotation is inclined by the same angle as the shaft with the deflection wheels. Now move the idler wheels and do it flat material to the sheet deposit stop, so there is a rotation of about 180 ° so that the blade is inclined at twice the angle of the shaft. If one stack part is to be moved relative to another, the shaft of their perpendicular position to the transport direction preferably once in one direction and slanted once in the other direction so that the offset is an angular offset one stack part compared to the other stack part, which is four times the Inclination of the shaft. Of course, the wave could also happen be aligned perpendicular to the transport direction and for the next stack part be inclined.
  • the sheets are turned at the same time by the sheet depositing device. This Advantage as well as some others relate to the sheet depositing device of the stand the technology, therefore reference is made to DE 23 09 075 A1.
  • the deflecting wheels are expediently designed in such a way that they each have two Have receptacle slots offset by 180 °. So the storage position is the one Receiving slots identical to the receiving position of the receiving slots offset by 180 °. In this way, the deflection wheels with every half turn pick up a new sheet and drop the previous sheet.
  • the deflection wheels with respect to their weight and the shaft with respect their storage are designed such that the deflection wheels through the feed of the flat good can be driven.
  • An alternative provides that a drive for the deflection wheels is provided. Then can be provided instead of the braking device that the drive is designed such that he stops the idler wheels in the receiving positions. For example, for this a stepper motor can be used.
  • the drive can drive the shaft even when it is inclined it is possible to arrange this directly on the shaft so that it is inclined participates.
  • the drive in the machine housing is arranged and is transmitted to the shaft.
  • the shaft pivoted about a pivot axis it can be provided that the Swivel axis is designed as a hollow shaft, in which there is a power transmission shaft of the drive.
  • the receiving slots are preferably V-shaped at the beginning of the slot. In this way it is ensured that the flat material is safely received and the receiving slot can be made so narrow after the beginning of the slot that the flat goods are held securely.
  • the slots should be be carried out as closely as possible.
  • at the at least one receiving slot Braking device for the flat material is provided, which this before the stop on The end of the slot deprives the speed so that there is no bouncing on the Attacks coming.
  • the braking device is designed as resilient tabs are, which are arranged in the region of the receiving slots and opposite the flat goods have friction. For example, rubber tabs can be provided his.
  • the Tabs are movable in the insertion path of the flat goods. This makes it possible to move them in the insertion position in the insertion path and in the storage position to remove from this so that the sheet deposit is not hindered. It will therefore proposed that the braking device for the flat material in the sheet deposit position is unlocked. Moving the braking device into the engagement and release position can be done, for example, by means of an eccentrically mounted weight, that transports the tabs in the insertion position into the insertion path and in the Storage position removed again from the area of the receiving slots.
  • the sheet deposit stop with respect to its angular position is adjustable. Then an adjustment corresponding to the inclination of the Wave can be made.
  • the angle setting the sheet deposit stop coupled with the angular setting of the shaft is that the inclination of the sheet tray stop is always twice the angle of the Inclination of the shaft corresponds. In this way the sheet tray stop has automatic the right position.
  • An alternative embodiment provides that the shaft from the perpendicular to the direction of transport is inclinable in both directions by a predetermined angle and that the sheet filing stop is V-shaped, each leg of the V each has twice the angle as the angle predetermined for the shaft. On In this way, the angular offset in the shelf is specified, however, one Setting of the sheet deposit stop saved, since one leg of the V-shaped one Training has the correct position at one of the predetermined angles.
  • a corresponding design of the sheet feed ensures that it always for exact positioning of the flat material in the receiving slots comes.
  • at least one transport roller can be located on the sheet feeder the flat good.
  • the sheet depositing device 1 essentially consists of a sheet feeder 5 and at least two deflection wheels 3, in this exemplary embodiment there are four, which are arranged on a shaft 9.
  • the deflection wheels 3 have receiving slots 4 arranged in the same position with respect to the rotation 25 (see FIG. 3), two receiving slots 4 being arranged offset by 180 ° for each deflecting wheel 3. Compared to the sheet feeder 5 offset by approximately 180 ° - this is the lower region of the deflection wheels 3 - there is a sheet storage stop 7 which has cutouts 8 in which the deflection wheels 3 move.
  • the sheet abuts against the sheet deposit stop 7 and becomes pushed out of the receiving slots 4 by the latter and on the filing stack 20 filed.
  • the sheet By reversing the sheet by 180 ° the doubles Inclination angle of the blade with respect to the inclination of the shaft 9, so that a corresponding angular misalignment in the stack 20 is achieved.
  • the shaft 9 turns out once in a direction of rotation with respect to the transport direction 10 pivoted out of their vertical position and to deposit one opposite first stack part 20 'offset stack part 20 "by the same angle in the other Swiveled direction, it is thereby achieved that stack parts 20 'and 20 "are formed, which have an angular offset by four times the inclined position of the shaft 9. If the shaft 9 is inclined by an angle ⁇ , then the inclination is the stack parts 20 'and 22' against each other four times the angle ⁇ .
  • the sheet deposit stop 7 extends laterally of the recess 8 in such a way that it lies to the side of the receiving slots 4 when they reach the sheet depositing position 17, whereby the sheets abut the stop 7 from the receiving slots 4 pushed out and put down. This is explained in more detail with reference to FIG. 3.
  • FIG. 2 shows a plan view of the sheet depositing device 1 shown in FIG. 1. It can be seen how the sheet feeder 5 is preferably equipped with transport rollers 19, which are located in areas of guide plates 21 which are tongue-like between the deflection wheels 3. This guarantees a safe transport of the sheets into the receiving slots 4 of the deflection wheels 3. Due to the lateral offset of the shaft 9 by the angle ⁇ by means of a pivoting about a pivot axis 13, a first inclination of the blades by the angle ⁇ is achieved, this angle ⁇ increasing due to the turning of the blades and when the blades are deposited on a blade tray 22 doubled an angle 2 ⁇ .
  • the sheet deposit stop 7 is V-shaped is, the two legs 18 from the perpendicular to the transport direction 10th each have an angle 2 ⁇ .
  • FIG. 3 shows a side view of an exemplary embodiment of the sheet depositing device 1 according to the invention with further functional elements.
  • the sheet feeder 5 was advanced somewhat counter to the transport direction 10 in order to be able to uncover the area of insertion of the flexible flat material 2 - that is to say the sheets - into the receiving slots 4.
  • a configuration as described for FIG. 2 is also expedient here.
  • the sheet depositing device 1 is in side view compared to FIG. 2 shown, a further functional element being a braking device 11 for the Deflection wheels 3 is arranged.
  • This consists of an arranged on the shaft 9 Cam 27, which has elevations 28. With this cam 27 acts a resilient element 29 together, which is arranged and designed such that it stops the deflection wheels 3 whenever the resilient element 29 against one of the Increases 28 runs.
  • the upper receiving slot 4 is in this position its receiving position symbolized by arrow 6 and the lower receiving slot 4 in its sheet deposit position symbolized by arrow 17.
  • a braking device 15 for the flat Goods 2 which consist of a tab 23 and an eccentrically mounted Weight 24 exist.
  • the weight 24 ensures that the tabs 23 are always up are directed and thereby the speed of a flexible, flat good 2 brake so that there is no bouncing on the attacks 16 is coming.
  • the flat good 2 was turned so that the former Sheet end 26 now lies at the front on sheet tray 22.
  • This illustration is also good visible how the receiving slots 4 are widened V-shaped at the beginning of the slot by one To ensure safe insertion of the flat goods 2.
  • Fig. 4 shows an embodiment of a sheet tray 22, the remaining parts already described are omitted to make the sheet tray 22 more visible.
  • the sheet deposit stop 7 is formed with legs 18 arranged in a V-shape, each offset by the angle 2 ⁇ , this is the double angle of the inclined position which is provided for the shaft 9. This results in a clean contact of the sheets 2 on the sheet deposit stop 7, since the sheets have already been brought into the angular offset 2 ⁇ by means of the deflection wheels 3.
  • the angular misalignment has been exaggerated, in fact a much smaller misalignment is required to achieve the purpose according to the invention described at the beginning.
  • Fig. 5 shows an embodiment of a drive 12 with shaft 9 and pivot axis 13.
  • the pivot axis 13 is designed as a hollow shaft in which a power transmission shaft 14, driven by the drive 12, runs centrally ,
  • the drive 12 is arranged in the machine housing 30 and the pivot axis 13 is rotatably mounted in the machine housing 30.
  • the power transmission of the power transmission shaft 14 to the shaft 9 takes place by means of a gear, two bevel gears 31, for example, being able to be arranged in order to transmit the rotational movement of the vertical power transmission shaft 14 to the horizontal shaft 9.
  • the swivel axis 13 is held in its swivel angle by means of a ring gear 32 and a gear wheel 33, the ring gear 32 and the gear wheel 33 also serving to carry out the swivel movement for the shaft 9.
  • a drive 12 can a braking device 11 can be combined or it is possible that the drive 12 does the positioning itself, for example by arranging a stepper motor becomes.
