Definitions
- the invention relates to a single sheet filing device for printing or copying devices for building a stack of single sheets.
- Fast printing devices for printing single sheets e.g. are known from WO-89/08282 contain filing devices for filing the printed single sheets.
- these filing devices which can be part of filing containers, the printed sheet is deposited with the printed side down and thus a stack of printed single sheets is formed. This means that in the stack the first printed side is at the bottom and the last printed side is at the top.
- the printing device contains two or more independent output units with automatic switching.
- EP-B1 0 213 426 describes a paper stacking device for preformed continuous paper, in which the paper web is fed to a storage table from below and the paper stack builds up from below.
- WO 92/11668 discloses a single-sheet depositing device for printing devices for building a stack of single sheets.
- the stack is shaped by two Transport systems for single sheets constructed from roller cages.
- Each of the roller cages has, on its circumference, roller-shaped transport elements which extend in the axial direction of the roller cages and are spaced apart by gaps. They individually wrap separate partial storage areas of a common inner storage surface that snaps through the two roller cages to accommodate the single sheets to be deposited.
- the roller cages grip the individual sheets to be stacked in the middle and transport them to a storage position arranged above or below the roller cages.
- the transport elements designed as transport rollers roll on the single sheets or on sheet packs from single sheets.
- the filing device for single sheets thus formed is universally suitable both for stacking from below and from above, but comprises a relatively large number of components, such as, for example, roller bearings and drives, which require regular maintenance in order to work without interference.
- the invention is based on the object, a single sheet filing device for printing or copying devices for building a stack from a single sheet of the type mentioned in such a way that it is possible to build a stack of single sheets so that it grows from the bottom up, so that the single sheets can be removed at any time and without interrupting the batch operation.
- the single-sheet depositing device should be simple and trouble-free and should enable the single sheets to be deposited continuously. This task is solved in a storage device of the type mentioned at the outset in accordance with the features of patent claim 1. Advantageous embodiments of the invention are characterized in the subclaims.
- the single sheets From the single-sheet transport path, on which the emzelo leaves are transported, for example, between pairs of rollers, the single sheets arrive in the single-sheet discharge area of the single-sheet depositing device.
- the individual sheets are accelerated accordingly by the last pair of transport rollers in such a way that they are guided by this energy supply by means of individual sheet aligning means into their desired position on the single sheet take-up table.
- the surface of the single sheet receiving table is smaller than the area of the single or multiple inserted single sheets, so that in the desired position the edge areas of the single sheets protrude on all sides over the single sheet receiving table.
- the single sheet cassette is arranged in the stacking direction above the single sheet take-up table.
- the cross section of the cut sheet cassette is at least as large as the area of a cut sheet.
- An opening is made in the side of the single sheet cassette facing the single sheet receiving table.
- a support means that reduces the cross section of the opening is arranged.
- the cross section of the opening which is determined by the inner circumference of the support means, is adapted to the shape of a single sheet and is smaller than the area of a single sheet.
- Crosspieces surrounding the opening serve as support means. These webs can form a closed ring, which can also be interrupted one or more times. It should only be noted that the edge areas of a single sheet printed last from the single sheet receiving table through the opening of the single sheet cassette and thus past the support means can be supported on the mounting device in such a way that they can no longer get from the single sheet cassette through the opening into the single sheet sausage area.
- the stacking direction is selected so that it always counteracts a portion of the weight of the already stacked single sheets.
- Preferred angles of the stacking direction to the horizontal are 90 °, 45 ° and 30 °. However, any other angle is possible.
- the angle of the stacking direction to the plane, in which the cut sheets rest on the support means of the cut sheet cassette, is approximately 90 °.
- the single sheet receiving table must always lift the single sheet stack already in the single sheet cassette against its weight in the stacking direction. This leads to a shock, the intensity of which depends on the size of the weight. To reduce the impact, the angle of the distance to the horizontal must be kept as small as possible.
- the single sheets can be transported individually or in groups by moving the single sheet receiving table in the stacking direction through the opening m of the single sheet cassette out of the single sheet area. As the stack of single sheets grows from below, single sheets can be removed from the top of the stack at any time.
- a particularly simple and low-maintenance drive tur the single sheet receiving table can be realized by a motor and a shaft driven by the motor, on which an eccentric disc is attached, which is coupled to the single sheet receiving table, for example via a slide or roller bearing.
- Other drive options are articulated rod drives, transmission drives, chain drives, etc.
- the single sheets transported from the last pair of rollers into the single-sheet insertion area are guided laterally through guide rails that are arranged in parallel in the direction of throw-in and braked by an end stop directed perpendicular to the direction of the down-stream.
- This is a particularly effective and very simple and therefore low-maintenance alignment agent.
- the storage accuracy of the single sheets on the single sheet receiving table can be further increased.
- damping material such as e.g. Foam rubber, foam, etc. must be brought up.
- a counter stop is provided diametrically opposite the end stop. The distance between the end stop and the counter stop is adapted to the length of a single sheet. An inserted single sheet hits the damping material, which dampens a possible rebound of the single sheet and ensures that the single sheet is placed safely on the single sheet receiving table together with the counter stop. After insertion, the single sheet lies in a defined position on the single sheet receiving table surrounded by the guide rails, the end stop and the counter stop.
- At least one Langioch directed in the direction of throwing can be introduced into the single-sheet receiving table or in an area upstream of the single-sheet receiving table in the infeed direction.
- an embossing nose which protrudes from the surface of the single sheet receiving table, is movably arranged.
- the smallest possible distance between the end stop and the insertion lug is adapted to the length of a single sheet.
- the embossing nose is coupled to the drive device for the single sheet receiving table in such a way that an inserted single sheet which comes to lie in front of the current position of the embossing nose is then pushed by the embossing nose in the direction of the end stop over the single sheet receiving table.
- the single sheet then lies exactly positioned on the single sheet receiving table between the guide rails, the end stop and the embossing lug.
- This functional unit can be displaced in the insertion direction and / or transversely to it with the aid of a sliding device coupled to the functional unit, which is implemented, for example, by a lifting magnet or a servomotor, in such a way that the subsequent single sheets are deposited laterally offset from the previously stored single sheets.
- the single sheet stacks are stacked from below in a single sheet cassette. This makes it possible to remove single sheets at any time and without interrupting printing. To enable this removal, the single sheet cassette can be designed differently. In the case of corresponding requirements, it may be sufficient to provide two fixed, adjacent side walls in the stacking direction, while the other two sides are open. The single sheets can then be removed from two sides.
- the single sheet cassette is formed by four side walls, at least one of which can be folded down and one can be moved.
- the foldable page gives access to single sheet removal.
- the sliding side wall enables the cut sheet cassette to be adapted to different cut sheet formats.
- the foldable side wall of the single sheet cassette can be used same stacking accuracy can be dispensed with in that a spring means is attached to the boundary of the displaceable side wall directed in the stacking direction, which does not adjoin a fixed side wall.
- This spring means acts at an angle of approx. 45 ° to the fixed side walls against the stack of single sheets.
- a leaf spring or a foldable part printed against the single sheet stack by a torsion or spiral spring serves as spring means.
- a weight for example a flat plate
- the weight can consist of transparent material, for example plexiglass, so that a viewer can see at any time whether a single sheet is already in the single sheet cassette.
- the format of the single sheets can also change for different jobs.
- the single sheet receiving table can be composed of several partial tables. Each sub-table is coupled to a selectively activatable drive device. This makes it possible to start up the individual dividing tables only when they are required in accordance with the format of a single sheet.

- a single-sheet page printing device which works according to the electrographic principle, as is known, for example, from WO 89/08282, has a depositing device for single sheets 2 for constructing a stack of single sheets 2.
- the single sheets 2 are fed to this depositing device from a single sheet transport device of the printing device.
- a pair of transport rollers 1 is arranged at the end of the transport path the single sheets 2 detected by him are accelerated so that they reach an insertion area 3 of the depositing device.
- the single-sheet depositing device contains a single-sheet receiving table 4 which can be moved in the vertical direction by a drive device 5, 6, 7, that is to say in a stacking direction 55 oriented at an angle of 90 ° to the horizontal.
- the drive device contains a motor b, ⁇ er drives a shaft 8 on which an eccentric 6 is attached.
- the eccentric disc 6 is located in an opening in an actuating rod 7.
- the actuating rod 7 acts directly on the single sheet receiving table 4, with the underside of which one end of the actuating rod 7 is connected.
- the single sheet receiving table 4 is surrounded by single sheet alignment means 11, 12, 13 and forms a functional unit with these.
- the functional unit consists of a rectangular base plate 14, on which guide rails 11 are attached on both sides in the insertion direction, from the base plate 14 to a single sheet cassette 1b.
- the guide rails 11 are connected at their ends by flat surfaces standing at right angles to the guide rails 11 and projecting from the base plate 14 in the direction of the single sheet cassette 15.
- the flat surface which marks the end of the insertion area 3, forms an end stop 12 for the inserted single sheet 2.
- Diametrically opposite the end stop 12, the second flat surface protrudes from the base plate 14 to the single sheet cassette 15. This second flat surface forms a counter stop 13 for the inserted single sheet 2.
- the single sheet 2 passes between the upper edge of the counter-stop 13 and the lower edge of the single-sheet cassette 15 into the insertion area 3. There it slides over the surface of the single-sheet receiving table 4 to the end stop 12.
- a damping material for example a foam rubber surface ge, angry. Due to the damping effect of this damping material 16, the thrown-in single sheet 2 is braked and slides over the upper edge of the counter-stop 13 m through the throwing-in area 3.
- the throwing-off area 3 is delimited on all sides by the single-sheet aligning means 11, 12, 13.
- the distance between the lateral guide rails 11 is adapted to the width of a single sheet 2 and the distance between the damping material 16 of the end stop 12 and the counter-stop 13 is adapted to the length of a single sheet 2.
- the orientation of the single sheet 2 on the embedding table 4 is precisely defined.
- the single sheet receiving table 4 is movably guided in the base plate 14 in the vertical direction.
- the actuating rod 7 is surrounded by a bush 10 which is introduced into a vertical penetration of the base plate 14.
- An additional guide is achieved by a guide rod 9 projecting perpendicularly from the underside of the single sheet receiving table 4. This guide rod 9 is guided vertically in a second opening 17 of the base plate 14.
- the single sheet receiving table 4 is moved upward in the direction of the single sheet cassette 15 by rotating the eccentric disk 6.
- the single sheet receiving table 4 penetrates the single sheet cassette 15.
- the single-sheet cassette 15 has an opening on its underside facing the functional unit.
- Support means 18 are arranged in the periphery of this opening. These bearing means 18 are formed by a flat sheet metal frame 18.
- the sheet metal frame 18 is fixed, for example by bending or spot welding, with two adjacent vertical vertical rare walls 19, 20.
- the sheet metal frame 18 allows a Single sheet with each of its edge areas on the sheet metal frame 18.
- the cross section of the opening in the single sheet cassette 15 is accordingly reduced by the sheet metal frame 18 so that it is smaller than the area of a single sheet 2.
- the area of the single sheet receiving table 4 is in turn smaller than the cross section of the Opening.
- FIGS. 4 to 5 show the sequence of a process in which a single sheet 2 is pressed from the single sheet receiving table 4 through the opening in the single sheet cassette 15 and thus through the sheet metal frame 18.
- the single sheet receiving table 4 moves upwards in the vertical direction, its surface reaches the plane formed by the sheet metal frame 18.
- the single sheet 2 protrudes on all sides above the single sheet receiving table 4.
- the area of the single sheet 2 is larger than the opening in the sheet metal frame 18, while the area of the single sheet receiving table 4 is smaller than the cross section of the opening in the sheet metal frame 18.
- the edge regions of the single sheet 2 which protrude above the single sheet receiving table 4 are printed downward by the sheet metal frame 18.
- the single sheet 2 is printed flat from the single sheet receiving table 4 against a single sheet stack 21 already present in the single sheet cassette 1b. This has the effect that the single sheet 2 rests non-slip on the single sheet receiving table 4.
- the single sheet receiving table 4 is now moved further upwards by its drive device 6, 7, 8.
- the Emzelblattstapei 21 is raised until the edge areas of the single sheet 2 are released from the sheet metal frame 1b and can relax in the direction of the single sheet stack 21.
- the edges of the single sheet 2 are then above the top of the sheet metal frame 18.
- the single sheet receiving table 4 is then moved downward in the vertical direction.
- the single sheet stack 21 lowers onto the sheet metal frame 1b.
- the edge areas of the single sheet 2 last printed by the single sheet recording table 4 through the opening of the single sheet cassette 15 are supported on the surface of the Sheet metal frame 18.
- the single sheet receiving table 4 is again in its lowest position, in which a further single sheet 2 can be inserted into the single sheet discharge area 3.
- the weight is 22 m of the single sheet cassette 15 intended.
- the weight 22 is vertically movable in an elongated hole 30 which is made in one of the side walls 20.
- the weight 22 thus ensures the functional reliability of the depositing device at the beginning of the depositing work.
- a printing device should be able to process several jobs in succession. It is desirable that a single sheet stack 21 which is assigned to a specific job can be easily distinguished from another single sheet stack 24 which is assigned to another job. This is achieved by a so-called job offset 28 of the single sheet stacks 21, 24.
- the single sheet filing device according to the invention is capable of generating such a job offset 28 of the individual sheet stacks 21, 24.
- the functional unit has a second support means 23, which is essentially congruent with the support means 18 of the single-sheet cassette 15.
- This support means 23 is firmly connected to the guide rails 11 and the end stop 12 of the functional unit.
- an insertion slot 25 is formed through which the single sheets 2 m pass through the insertion area 3.
- the first support means 18 and the second support means 23 are congruent with one exception. This exception is represented by the distance between the regions of the support means 18, 23 located above the end stop 12 and above the counter stop 13. With the second support means 23, this distance is smaller by the job offset 28 than with the first support means 18.
- FIGS. 1 and 2 show the two possible positions of the functional unit relative to the single sheet cassette 15.
- the functional unit can be displaced by the job offset 2b in a displacement direction 27 which is aligned with the insertion direction by means of a displacement device 26.
- the displacement device 26 consists of a lifting magnet which is coupled to the functional unit via a lifting rod 29.
- the displacement device 26 can also be realized by an actuator or a hand lever, which act in the displacement direction 27.
- the functional unit slides, for example, in suitable guide rails, which are fixed to the frame in the single-sheet depositing device.
- the motor b, the shaft 8 and the eccentric 6 are also fixed to the frame m of the single sheet depositing device.
- the actuating rod 7, in the recess of which the eccentric disc 6 is located, slides during the shifting process in the axial direction over the eccentric disc 6.
- the thickness of the eccentric disc 6 is selected accordingly so that in both possible positions of the functional unit the actuating rod 7 does not have one of the two axial ends the eccentric 6 protrudes.
- the displacement device 26 is actuated either by a control signal generated by the printing device or by a person operating the printing device.
- the functional unit is displaced in the opposite direction of displacement 27 and thus reaches the other position.
- those stored in this position Single sheets 2 are placed flush with the fixed side wall 20 of the single sheet cassette 15, in which the elongated hole 30 for guiding the weight 22 is placed.
- the areas of the support means 1b, 23 arranged above the counter-stop 13 have inner edges aligned with one another in this position.
- the areas of the support means 18, 23 arranged above the end stop 12 have offset inner edges. The offset corresponds to the job offset 2b.
- the inner edge of the corresponding area of the second support means 23 projects beyond the inner edge of the corresponding area of the first support means 18.
- the single sheets 2 are deposited at the job offset distance 28 from the fixed side wall 20, which has the elongated hole 30.
- the inner edges of the regions of the support means 18, 23 arranged above the end stop 12 are aligned.
- the regions of the support means 18, 23 which are located above the counter stop 13 have mutually offset inner edges.
- the inner edge of the second support means 23 protrudes beyond the inner edge of the first support means 18.
- a further horizontal job offset 28 perpendicular to the displacement direction 27 can be realized in accordance with the job offset 28 m of the displacement direction 27.
- the individual sheet stacks 21, 24 are not offset in the direction perpendicular to the direction of displacement 27 but are placed flush (see FIG. 3) on the fixed side wall 19 not having the elongated hole 30.
- FIGS. 7 to 9 show further embodiments of the single-sheet depositing device.
- the single sheet filing device according to FIG. 7 contains a rectangular single sheet cassette 15 which has four side walls, three of which are fixed and one side wall 31 can be folded down. The distances between the side walls are such that the gesta pelt single sheets 2 lie flush on at least three of the four side walls.
- the hinged side wall 31 is rotatably supported at its lower end about a horizontal axis of a joint 32. With the aid of a knob 33 projecting outwards, which is connected to the foldable side wall 31 and additionally actuates a locking device (not shown), the side wall 31 can be flipped outwards. When the side wall 31 is folded away, the single sheets 2 can be removed.
- the single sheet throwing area 3 is delimited by the lateral guide rails 11a and the end stop 12.
- the lateral guide rails 11a and the end stop 12 are part of the single-sheet cassette 15.
- the side walls of the single-sheet cassette 15 are projecting inwards. These projections have a U-shaped profile, the open side of this profile facing the center of the opening of the single sheet cassette 1b facing the single sheet receiving table 4.
- the single sheets 2 are guided laterally between the legs of the U-profile when they are thrown into the sausage area 3.
- the end stop 12 also has a U-profile aligned with the center of the opening. However, this U-profile extends only over a relatively small area centered between the two lateral guide rails 11a.
- the single sheet receiving table 4 consists of a flat sheet metal, which is bent on its four sides to vertical table walls 34. These table walls 34 are used for vertical guidance of the single sheet receiving table 4a.
- a shaft ba runs below the table surface parallel to the table surface and perpendicular to the lateral guide rails 11a.
- This shaft 8a is axially coupled to the motor 5a via a clutch 34.
- the ends of the shaft 8a are rotatably gela in frames 35 fixed to the frame via bushings 36 device.
- the shaft 8a penetrates the table walls 34 perpendicular to the shaft 8a. In the penetration area, the table walls 34 have vertical table slots 38. The width of the table slots 38 corresponds approximately to the diameter of the shaft ba.
- the single-sheet receiving table 4a is fixed in the axial direction of the shaft 8a by means of locking rings 37 which are axially immovably pushed over the shaft 8a directly next to the opposite table walls 34.
- An eccentric disk 6a is fastened on the shaft 8a between the retaining rings 37 in the vicinity of a table wall 34.
- the two eccentric disks 6a slide on the underside of the single sheet receiving table 4a and move it in the vertical direction.
- the single sheet receiving table 4a is guided by the shaft 8a, which slides in the elongated table holes 38 and through the remaining table walls 34 on supporting means 39 attached to the outside.
- the support means 39 are formed by frame-fixed sliding surfaces provided near the table wall 34.
- FIG. 8 shows the section through the single sheet depositing device shown in FIG. 7.
- the single sheet receiving table 4 consists of two partial tables 4a, 4c, a drive device 6a, 6c acting selectively on each partial table 4a, 4c.
- the surface of this single sheet receiving table 4a, 4c is vertically inclined in the infeed direction 40 of the single sheets 2. Starting from the insertion slot 25, the surface of the single sheet receiving table 4a, 4c rises continuously up to the end stop 12. As a result, an inserted single sheet 2 is braked on the one hand, and on the other hand the impact against a single sheet stack in the single sheet cassette 1b is alleviated because the surface of the single sheet receiving table 4a, 4c does not abut the single sheet stack in its full area.
- a drive device consisting of a motor ba, a shaft 8a, 8c and an eccentric disk 6a, 6c, is assigned to each of the subtables 4a, 4c.
- the drive devices can be rigidly coupled to one another, then a second motor 5c is omitted, or else coupled to one another in such a way that a sub-table 4a, 4c is only moved when the size of the single sheet 2 so requires.
- the two sub-tables 4a, 4c are not immediately adjacent.
- a support means 39 is arranged between them, which serves for the vertical guidance of the two partial tables 4a, 4c. In addition, this support means above the single sheet receiving table 4a, 4c clears an area m that the single sheet receiving table 4a, 4c does not penetrate.
- a removable or displaceable side wall 41 can optionally be introduced into this area. This is necessary, for example, if, instead of a single sheet format of the large DIN A3, a single sheet format of the large DIN A4 is to be stacked by the single sheet filing device.
- the removable or displaceable side wall 41 like the possibly fixed side wall 42, which is used to store the single sheet format DIN A3, has a single sheet support means 18a at its lower end.
- a further support means 43 is arranged in front of the two subtables 4a, 4c of the single sheet receiving table 4 in the single sheet throw direction 40. On the one hand, this support means 43 serves to guide the partial table 4c vertically, on the other hand it extends the surface of the single sheet receiving table 4 counter to the direction of insertion 40.
- the supporting means 43 thus forms a plane upstream of the single sheet receiving table 4.
- An elongated recess 44 is introduced into this plane in the insertion direction 40.
- an insertion nose 4b which is movable in the insertion direction 40 and protrudes beyond the surface of the support center 43, is arranged.
- the thrust nose 4b is coupled to the shaft bc of the drive device of the dividing table 4c.
- An inserted single sheet 2 is gripped on its rear side by the insertion nose 45 and pushed up to the end stop 12. The smallest possible distance between the end stop 12 and the insertion nose 45 is adapted to the length of a single sheet 2.
- FIG. 9 shows a single-sheet cassette 15 which has two adjoining test side walls 47, 48, is open to one side and has on one side a displaceable side wall 51, the vertical boundary of which is not adjacent to a fixed side wall 47, 48 by means of an angle of about 45 ° to the fixed rare walls spring means 46 is formed.
- the individual sheet stacks lie flush against the fixed side walls 47, 48.
- the removable and the fixed side wall 41, 42 from FIG. 8 are replaced by the sliding side wall 51.
- the displaceable side wall 51 is coupled to a side wall displacement device 50.
- this side wall shifting device 50 which is formed from corresponding guide means and a manual or automatic adjusting device, the shiftable side wall bl can be shifted parallel to the fixed side wall 48 opposite it.
- the single sheet cassette 15 can thus be continuously adjusted to the length of a single sheet 2 to be deposited.
- the displaceable side wall 51 is not fully formed. Rather, it consists of a support frame 52 and two eccentric rollers 53, 54 located at the opposite ends of the support frame.
- the axis of rotation of the eccentric rollers 53, 54 is directed vertically. With the help of the eccentric rollers 53, 54, the distance between the fixed side wall 48 and the displaceable side wall 51 on both sides of the supporting frame mens 52 can be finely adjusted. A high storage quality can thus be achieved.
- the spring means 46 designed as a leaf spring is fastened to the end of the support frame 52 facing away from the fixed side wall 47. Due to the resilient effect of the spring means 46, removal of the single sheet stack in the removal direction 49 is possible in a simple manner.
