Definitions

  • the invention relates to a sheet retainer for a non-stop stack changer according to the preamble of the claim 1.
  • Such a so-called non-stop device can consist, for example, of a rake-like device that can be inserted into the stacking area of the sheet feeder.
  • the device adopts a remaining stack remaining from a sheet stack, the carrying device for the previously processed sheet stack being removed and provided with a new carrying device by a new sheet stack.
  • the non-stop device holds and lifts the remaining stack.
  • retainers in non-stop devices.
  • strip-like elements are arranged on the side or on the rear end side, which generate a supporting force with respect to the sheet stack or the interface between the remaining stack and sheet stack, so that the rake of the non-stop device can be produced without an offset in the interface of the stack , can be pulled from the stacking area.
  • EP 0 531 786 B1 is a sheet feeder known with a non-stop facility.
  • One is described Device for temporarily carrying a stack of leftover sheets by means of a computing grid.
  • the computing grid is by means of a lifting and driving device in the stacking area of the Insertable sheet feeder. When changing stacks, it will Computing grid for merging the remaining sheet stack and the main stack pulled out between the stack parts. To avoid of arc shifts at the union point a restraining rail against the remaining sheet stack and the main stack employed and held there with force, as long as that Grid is to be drawn.
  • the computing grid extends over the full stack width and must absorb high forces.
  • the aim of the invention is one or more retaining elements provide the optimal effect with the least effort produce.
  • the object of the invention is therefore in a device according to the preamble of claim 1 in the simplest Way to integrate retention elements that are low on the one hand Generate construction costs and secondly low Apply forces to the edges of the paper so that no damage are to be expected.
  • the retaining elements can be connected to any supporting bars.
  • Prefers can the corresponding support rods with a measuring system be connected so that by means of the retaining elements Format detection can be done on the sheet stack.
  • the retaining elements can be in different embodiments be provided. So it is possible to use the retention elements to only have an effect on the remaining stack.
  • FIG 1 is the assignment of a sheet processing machine 1 to a sheet feeder 2 shown.
  • the sheet feeder 2 is provided with a sheet stack S by means of a separating device 4 processed and in a stream of flakes is conveyed to a belt table 20.
  • the conveyor table 20 leads the shingled stream to the sheet-processing machine 1.
  • a non-stop device 3 is provided on the sheet feeder 2.
  • the non-stop device 3 is by means of a hoist 5 on lifting rails 8 integrated in the sheet feeder 2 and off moves.
  • the non-stop device 3 has a frame 6 provided, in the longitudinal direction support rods 7 are movable.
  • the support rods 7 can be driven into the stacking area by means of a drive the sheet feeder 2 and the sheet stack S be retracted. There you can take over a remaining stack, the through the extensive processing of the sheet stack S arose.
  • the hoist 5 ensures that the Remaining stack supporting rods 7 over the entire height of Stack area can be moved.
  • the basic function of the restraint device is shown in FIG.
  • a remaining stack R sits on the support rods 7; these in turn are touched by the sheet stack S from below.
  • a retaining element 10 is placed against the end faces of the remaining stack R and sheet stack S.
  • the retaining element 10 is connected to a guide rod 11.
  • the guide rod 11 has a toothing 12 on its side.
  • a drive pinion 13 of an actuator 14 engages in the toothing 12 of the guide rod 11.
  • the retaining element 10 can thus be both moved against the sheet stack and removed from it by means of the guide rod 11.
  • the stops are made against the front edges of the stack parts.
  • the retaining elements 10 are usually provided in at least two versions and have only a relatively small width.
  • the retaining element 10 is guided with its guide rod 11 in the same way as the normal supporting rods 7 of the non-stop device 3. These are in a guide device 31 below a crossbar 30 of the non-stop device 3 and are driven by individual drives 32, which are arranged in the crossmember 30, via gear wheels 33. To unite the stack, the retaining elements 10 are thus set against the end stack edges and the support rods 7 are pulled out of the area of the sheet stack S or the remaining stack R.
  • the stack edges cannot be moved.
  • This in addition to the effect of the retaining elements 10 causes the support rods 7 individually and staggered are pulled out of the stacking area and that the Support rods 7 also preferably formed in two stages could be.
  • the sheets of the remaining stack R are thus initially reduced to the takeover position Intermediate stage and then only with the sheet stack S united so that the stack parts continuously and not on to be united in one stroke. This results in much less Restraining forces than when pulling the support rods together 7 in one operation.
  • FIG 3 is a plan view of the arrangement of support rods 7 and a retaining element 10 are shown in detail.
  • the Support rods 7 are with individual drives 32 and the retaining element 10 is with one acting on the guide rod 11 Actuator 14 provided.
  • the actuator 14 of the retaining element 10 is connected to a reduction gear, that via a bevel gear 17 and a shaft 15 with two bevel gears, and a reversing gear with another bevel gear 16, and the drive pinion 13 is constructed. So that the Drive point from the crossmember 30 to the front more in the proximity of the working position of the retaining elements 10 relocated become. Furthermore, by reducing the gear given the opportunity to generate a higher retention force.
  • the guide rod 11 can be shorter than one of the support rods 7. This can ensure that the guide rods 11 are not in the rear work area the non-stop device 3 protrude and the operation hinder. Cover the shortened guide rods 11 in each case the working area of the retaining elements 10 for all sheet formats to be processed.
  • FIG. 4 shows a retaining element 10 together with its Drive shown again in more detail.
  • the actuator 14 is connected to a bevel gear 17.
  • This bevel gear 17 meshes with another bevel gear on the shaft 15, which in one with the crossbar 30 connected bracket 18 is mounted.
  • bracket 18 On the opposite side of the shaft 15 is a second one Bevel gear arranged, which in turn with the larger bevel gear 16 combs.
  • the larger bevel gear 16 steps down and steers the drive movement into the vertical and is with the Drive pinion 13 connected.
  • the drive pinion 13 and that Larger bevel gear 16 are also in the bracket 18 Anchored to shaft 15. They are arranged so that the drive pinion 13 in a side toothing on the guide rod 11 of the retaining element 10 engages.
  • the retention element 10 is in the illustrated embodiment in two parts. It is possible for the retaining element 10 in a slightly modified version so that only the upper half of the retaining element 10A on the Guide rod 11 is attached. Then the retaining element acts 10A only on the remaining stack R. This is for use cases useful where comparatively light and small Sheets of sheets to be processed.
  • a retaining element 10 of this type is shown in the device described at any position or possible in several positions, where support rods 7 are used are. It can be chosen so that even the smallest formats processable based on the sheet width by means of this device are. At the same time, it does not have to cover the entire width of the sheet stack S or the sheet feeder 2 a restraint be provided. This is also not necessary that the retention force is at a very low level lies and a correspondingly low pitch force required is.
  • the retaining elements 10 preferably on the thinner ones that only serve to form the distance Support rods 7 attached. It is no longer necessary there Continuous support across the entire stack width to ensure.
  • the guide rods 11 do not have to, as above described, be shorter than the support rods 7. It can in Difference to a then fixed position of the retaining elements 10, 10A also provided in the non-stop device 3 be that the retaining elements 10, 10A at any Support rods 7 can be attached interchangeably. To do this the retaining elements 10, 10A then, for example, with a simple clamp connection at the front end of the support rods 7 attachable or clampable. This also applies to the horizontal split version, which is described above.
