Definitions

  • the present invention relates to a flat machine for flattening sheets of paper or paper-like sheet material, according to the preamble of claim 1.
  • such machines are equipped with a plurality of folding rollers, each of which is functionally assigned to one another in pairs, a fold being formed between a pair of rollers per pass of the sheet to be folded.
  • folding rollers are made of steel and have a corrugated or otherwise machined surface; if necessary, individual surface areas of the rollers can also be formed by rubber pads or the like.
  • the two rollers of a cooperating pair of folding rollers must not be arranged rigidly to one another, because such a machine must be able to process sheets of paper or similar sheet material in different thicknesses.
  • the thickness can vary within certain limits, that irregularities, e.g. B. inclusions or the like in the sheet material, or that two or more sheets accidentally get between the rollers at the same time.
  • An, albeit adjustable, but rigid bearing of the rollers could lead to impermissibly high loads with possible destruction or damage to the roller bearings, since paper and similar bale material is known to be very hard. It is therefore necessary to resiliently mount at least one of the rollers of a cooperating pair of rollers in the radial direction.
  • Previously known flat machines of the type described at the outset generally have a machine frame which comprises two parallel bearing plates which are arranged at a distance from one another and between which the rollers are mounted on projecting shaft journals on both sides. These bearing plates serve at the same time to accommodate the necessary adjusting members or the resilient support device. Even to replace only one roller, it is necessary to disassemble or disassemble the entire roller assembly, i.e. to loosen and remove one of the bearing plates. Since such a machine usually comprises several rollers, such disassembly and in particular the subsequent assembly and adjustment of the rollers are relatively complicated and therefore time-consuming. The replacement of a roller or several rollers could also only be carried out by qualified specialists, which had a disadvantageous effect, in particular with regard to the amount of maintenance costs and the period of machine failure.
  • the design of the respective bearing member can be different.
  • To replace the drive roller it is thus easy to remove the bearing member and to pull the roller out, if necessary after loosening the drive means.
  • the bearing member comprises an anchoring part which is detachably fastened to the machine frame and a guide part which receives the shaft end of the roller and overlaps the assigned opening.
  • the guide part of the bearing member is expediently detachable and adjustable in terms of distance to the anchoring part of the bearing member. This measure makes it possible to detach the guide part from the anchoring part for the purpose of replacing the roller in question, to pull the former away from the shaft end of the roller and to remove the roller in the axial direction through the opening.
  • the joint opening provided according to the invention allows a design simplification, while at the same time ensuring that each individual of the rollers, after removal of the guide part, can be pulled out through this common opening.
  • the guide part is provided with a bearing bore which has a bearing bush which receives the shaft end of the associated roller.
  • a spindle is expediently provided, which is detachably received at one end in the guide part in a threaded bore running perpendicular to the bearing bore, which spindle also extends through a central bore in the anchoring part and which at the other end carries an actuating button.
  • the central bore in the anchoring part can at least partially have a larger diameter than the mentioned spindle and can accommodate a spring which is supported against a locking sleeve which is slidably inserted into the end of the central bore and is screwed onto the spindle.
  • the associated roller can be displaced in the simplest way with respect to the center distance of the other roller of this roller pair by axial displacement of the spindle, where appropriate suitable spacers between the actuating lever and Front of the anchoring part can be used to fix the center distance to a predetermined dimension.
  • the roller unit 1 shows a schematic side view of the roller unit, generally designated 1, together with the feed table 2 for sheets of paper or the like to be flattened, with a first folding pocket 3 and a second folding pocket 4.
  • the roller unit 1 has two lateral bearing plates 5, of which only one can be seen from FIG. 1.
  • the second bearing plate 5 is arranged parallel to it at a distance corresponding essentially to the roll width and is rigidly connected to the first bearing plate 5 by means of connecting struts (not shown) which are anchored to the bearing plates 5 with a number of screws 6.
  • the feed table 2, the first folding pocket 3 and the second folding pocket 4 are also fastened to the two bearing plates 5 by means not shown in detail.
  • the roller assembly 1 also includes a plurality of folding rollers, four in the present exemplary embodiment, namely a driven folding roller 7 and three further folding rollers 8, 9 and 10. These four folding rollers form three functionally associated folding roller pairs, as follows will be explained.
  • the driven flap 7 is rotatably anchored to the bearing plate 5 by means of a bearing element 11, while the folding roller 8 is rotatably supported on the bearing plate 5 by means of a bearing element 12, the folding rollers 9 by means of a bearing element 13 and the folding roller 10 by means of a bearing element 14. It goes without saying that an identical arrangement can be provided in the aforementioned second bearing plate 5, or is advantageously provided.
  • a sheet to be folded is inserted through the feed table 2 between the rollers 8 and 9 in a manner not shown; the two rollers 8 and 9 thus form a first functional pair.
  • The. leading edge of the sheet enters the first folding pocket 3 and is against the stop 15 which is adjustably arranged therein bump.
  • the folded sheet is now conveyed further by the rollers 7 and 8 and now comes with the falcon edge first into the second folding pocket 4 until the previously formed folding edge abuts the stop 16, which is also arranged to be adjustable.
  • the sheet section at this moment in the area of the rollers 7 and 10 is gripped by these rollers, so that the second fold is formed while the sheet runs between these two rollers 7 and 10; these two latter form the third, functional pair of rollers.
  • the sheet folded twice in this way is ejected behind the rollers 7 and 10.
  • rollers 8, 9 and 10 are each rotatably supported by means of two bearing members 12, 13 and 14, these bearing members mentioned having an anchoring part 12a, 13a, 14a fixedly attached to the bearing plates 5 and a displaceable relative to the anchoring parts , With respect to the distance adjustable and resiliently supported guide part 12b, 13b, 14b.
  • the detailed training of the last-mentioned bearing members and their components will also be discussed in more detail below.
  • the bearing plates 5 are provided with an opening 17, along the edge of which the individual bearing members 11 and 12 to 14 are fastened.
  • a single opening 17 is provided per bearing plate 5, the size of which is dimensioned such that it supports the axial side projection of all the rollers 7 to 10, including existing auxiliary elements such as, for. B. gears for mutual drive coupling of the individual rollers.
  • auxiliary elements such as, for. B. gears for mutual drive coupling of the individual rollers.
  • an anchoring part 11a is connected to the bearing plates 5, while an area 11b projects beyond the opening 17 and supports the roller 7.
  • the anchoring part 12a, 13a and 14a is fastened to the bearing plates 5, while the guide part 12b, 13b and 14b projects above the opening 17 and rotatably receives the respectively assigned rollers 8, 9 and 10.
  • FIG. 2 shows a view of the driven roller 7 along with a sectional illustration of the associated mounting of the roller 7.
  • the roller 7 is rotatably received in the two bearing plates 5 arranged parallel to one another, with the aid of the bearing members 11.
  • the bearing members 11 generally have a prismatic, elongated shape and are divided into an anchoring area 11a and a guide area 11b.
  • the anchoring area 11a is fastened to the associated bearing plate 5 by means of two screws 18, the screws 18 being screwed into an anchor plate 19.
  • guide sleeves 20 can be provided which are inserted into appropriately dimensioned bores 21 of the anchoring part 11a and of the bearing plates 5.
  • the guide part 11b of the bearing members 11 engages over the opening 17 and is provided in the region of its free end with a respective bearing bush 22 which rotatably receives the shaft end 23 of the roller 7.
  • the one of the two shaft ends 23 has an extension 23a which receives a drive wheel 24 for driving the roller 7.
  • the roller 7 is equipped with a gear 25 which meshes with a correspondingly arranged gear, not shown in FIG. 2, on the roller 8 and with a gear arranged on the roller 10, in order to drive it.
  • Fig. 3 is a roller driven by the roller 7, z. B. the folding roller 8, shown in a view with the associated storage in section. It goes without saying that, although in the following only reference is made to the mounting of the roller 8, the same applies analogously to the folding rollers 9 and 10 and their mounting.
  • the roller 8 is also equipped with two projecting shaft ends 23, which are generally rotatably accommodated in two bearing members 12; the latter are anchored to the associated bearing plates 5 by means of bonnets 26.
  • the roller 8 carries a gear 27 which meshes with the gear 25 of the roller 7, so that the roller 8 is set in rotation by the driven roller 7.
  • the bearing member 12 comprises an anchoring part 12a, which is fastened to the bearing plate 5 by means of the screws 26, and a guide part 12b, which receives the shaft end 23.
  • the latter is provided with a bearing bush 28 which is received in a bore 29 coaxial with the roller 8.
  • a screw 31 is screwed into a threaded bore 30, which runs perpendicular to the bore 29, which extends through a longitudinal bore 32 in the anchoring part 12a of the bearing member 12 and which carries an adjusting knob 33 at its upper end.
  • a locking sleeve 34 designed as a counter nut and screwed onto the spindle 31 is releasably clamped against the guide part 12b.
  • a cylindrical extension 34a of the locking sleeve 34 is slidably received in the bore 32, it being possible, if necessary, to provide a bearing bush 35 for guiding said extension 34a without play.
  • a part of the bore 32 in the anchoring part 12a is enlarged in diameter and receives a spring 36 which is supported on the one hand against the end of the cylindrical extension 34a of the locking sleeve and on the other hand against the final end region 37 of the anchoring part 12a.
  • the spring 36 thus endeavors to press the locking sleeve 34 together with the spindle 31 and the guide part 12b attached thereto. This displacement path is limited by the setting of the adjusting button 33 against the upper end face of the anchoring part 12a.
  • a cranked lever 38 is inserted in the area of its shorter lever arm 38a under the adjusting knob 33, so that actuating the longer lever arm 38b can cause the adjusting knob 33 to be lifted off the anchoring part 12a, so that a spacer plate (not shown) can be inserted in between to adjust the radial one To change or adjust the position of the axis of the roller 8.
  • the locking sleeve 34 is loosened somewhat, so that the spindle 31 can be removed from the threaded bore 30 of the guide part 12b by turning the adjusting knob 33. Now this guide part 12b can be pulled off the shaft end 23 and the roller 8 can be easily removed through the opening 17 in the axial direction.
  • the assembly of a new roller 8 takes place in the corresponding reverse order, it being only necessary to adjust it by actuating the adjusting knob 33 by screwing the spindle 31 into the threaded bore 30 by the correct amount and then tightening the locking sleeve 34 again against the guide part 12b.
