Definitions

  • the invention relates to a device for transporting and guiding individual, flat sheets, in particular isolated paper products in a circular shape, with at least one belt or chain-shaped conveyor.
  • corner deflection of lying flat structures in particular paper products, be it in the form of scales or in isolated form.
  • These corner deflections can be provided on the one hand for reasons of space, but on the other hand also for transporting the current to another treatment stage.
  • the distance between the individual treatment stages should be kept as small as possible in a compact construction of the entire treatment system.
  • the invention has for its object to provide a device of the type mentioned, in which a treatment of the fabrics, especially the paper products, on more than two sides in the shortest possible time stood apart from each other.
  • the object is achieved in a device of the type mentioned in the invention that according to the invention for punctiform detection of the flat structures at two spaced-apart locations on two conveyors running in approximately parallel circular sections with one another, pushbutton-shaped pins, bolts or the like. provided and the conveyors are each driven at the same speed.
  • the lateral treatment or processing of the paper products can be changed in the shortest possible way. For example, it is possible to treat a paper product trimmed on two opposite sides immediately after leaving the device on a third or on both other sides, e.g. to prune.
  • a preferred embodiment of the invention consists in that the conveyors are each in pairs and are designed as endless conveyors and are tangential at least at the inlet into the circular section.
  • a detection of the flat structures, in particular of the paper products, before the entry into the circular section is particularly preferable because this ensures a rotation-free guidance from the beginning of the circular section.
  • the endless conveyors are preferably in the form of roller chains or the like. educated.
  • the roller chains can on one side with driver pin or the like. be provided.
  • the pins or the like attached to an endless conveyor. as needles or the like which can be lowered onto the flat structures. and abutment with associated holes provided on the opposite endless conveyor.
  • the button-shaped pins or the like. formed with its abutment as a rotatable point bearing; the spring-loaded pins or the like pressing on the flat structures. on the one hand are formed on an endless roller chain conveyor and the pin-shaped abutments, which have a rotatable ball tip, are formed on the other endless roller chain conveyor.
  • the paired endless roller chain conveyors are expediently each on a frame or the like. appropriate.
  • all four conveyors are driven together; the two pairs of conveyors can be adjustable in both directions.
  • the frames or the like are preferably. on radially extending rods, rails or the like. slidable.
  • the spaced apart locations can be provided at diagonally opposite corners of the sheets.
  • a device for transporting and guiding multi-layer, optionally folded or trimmed or trimmed or trimmed or trimmed paper products in the size of 30 x 23 cm is shown, the paper products at two opposite point-shaped locations 2 and 3 - as further described in more detail below - are held and occasionally guided by an arc angle of 90 ° in such a way that the respective long sides form the transverse sides after the "corner deflection".
  • the inner radius 5 of the breakpoints 3 is, for example, 1 m.
  • the breakpoints 3 describe exactly one circular shape around the center point 6 in the corner deflection.
  • the outer breakpoints 2 describe a path which deviates from a possibly concentric circle to the circle 7, since its center 8 - as can be seen in FIG. 1 - is shifted to the top right.
  • the stopping point 2 again describes a circle 12, which, however, does not run parallel to the circle 7.
  • the circle 12 - likewise extending to 90 ° degrees of arc - extends from a transition point 10 to a transition point 11, with straight sections of the conveyors used being provided before or after these transition points.
  • the respective paper product is recorded at the latest at point 10 or point 13, while the paper products are released at the earliest at points 14 or 15.
  • the stops 2 and 3 connected by the dashed line 16 correspond to the respective centers 6 and 8 of the two quarter circles, so that these two centers determine the respective paths of the stops from the starting position to the starting position.
  • the outline of the paper product 1 ' is shown schematically with dashed lines.
  • a device for fixing the sheet or the paper product at the stop 3 is shown in more detail.
  • Holders 21, 22 are attached at short intervals to an example of a plate 20 bent according to the circle 7, which bear pins 23 and 24 in bores, each of which is assigned to a link chain or a roller chain 30 or 31.
  • the roller chain 30 belongs to an endless conveyor, the lower section of which represents the return thereof, while the roller chain 31 belongs to an endless conveyor, the upper returning part of which is not shown.
  • Block-shaped holders 35 for needles 36 are held on flat plates 33, 34 of the upper endless conveyor in accordance with DIN 8187 or DIN 8188.
  • At the bottom endless conveyor are over flat tabs 37, 38 block-shaped receptacles 39 are attached, each of which has holes 40 assigned to the needle tip.
  • the two endless conveyors of the roller chains 30 and 31 run synchronously and are also synchronized with the two endless conveyors on the right-hand side, that is to say in accordance with the circle 12. All endless conveyors run at the same speed.
  • the endless conveyors must extend at least from point 13 to point 15 in the inner circle and from point 10 to point 14 in the outer "circle".
  • an extended design of the endless conveyors is preferred in order to ensure the straight inlet and the straight outlet.
  • pairs of holders 51 and 52 for the upper endless roller chain are respectively attached to the inner quarter-circularly bent sheet metal 50, while the lower endless roller chain is carried by pairs of holders 53, 54.
  • pins 58 which are supported by springs 57 and have a rounded tip 59 are held on the respective flat tabs 55, 56.
  • the paper product or the like. 60 is held between the tip 59 and a rotatable ball 61 which is supported by the lower flat plates 62, 63.
  • the right part of the transport and guiding device is supported by two plates 70, 71 to which the holders for the two endless conveyors are attached. Outside the path, which corresponds to the semicircle 12, the two plate-shaped holders are e.g. firmly connected to one another by struts 72.
  • roller chain other, but non-slip, conveying means can also be used and that the roller chain is guided via the pins 23, 24.
  • a common drive 84 can be provided for all four endless conveyors; the power is then transmitted in the usual way by synchronous drive, e.g. all four idler gears on one side.
