Definitions

  • the invention relates to a belt transport system for transporting sheet material according to the preamble of claim 1.
  • Belt transport systems for transporting sheet material are known in multiple embodiments.
  • DE-OS 27 29 830 mentions such a transport system for transporting documents, banknotes or the like, which consists of several round belts running in parallel.
  • the round belts are guided and driven via pairs of transport rollers.
  • the transport belts are positioned so that the sheet material to be transported is clamped between the belts, fixed and can be transported in this way.
  • the transport system is divided into several transport sections in which the transport belts, which are designed as endless belts, circulate. At the beginning and at the end of these transport sections, deflection rollers are provided through which the endless belts are returned.
  • the transport of the sheet material clamped between the belts is relatively unproblematic when it is in good condition, ie with smooth, undamaged sheets. If the condition is poor, especially if there are dog ears or tears, there is a risk that parts of the sheet material from the normal transport plane are bent behind the transport belts to such an extent that they become jammed between the transport belts and transport rollers during transport. If this happens, for example, in the area of the deflection rollers or in areas in which the running direction of the endless belts deviates from the transport direction of the sheet material, at least the part of the sheet material clamped between the transport roller and belt becomes out of the intended transport direction in the running direction of the transport belt forced.
  • baffles either the pinched part of the sheet is torn off or the sheet is pulled between the transport roller and baffle in such a way that the transport path is blocked and the function of the transport system is no longer guaranteed. If no guide plates or the like are provided in the deflection area, the clamped sheet follows the running direction of the belt and is thus removed from the transport path, which is equally to be avoided.
  • JP-A 63-230467 which corresponds to the preamble of claim 1, shows a belt transport system in which the sheet material is transported in the clamped state between two transport belts.
  • a serrated sheet is provided on the back of the conveyor belt. This is arranged in such a way that the parts of the sheet material protruding behind the transport belts run onto the serrated sheet during transport. The parts protruding behind the conveyor belts are either cut off by the "scraper" or folded inwards onto the sheet material.
  • the serrated sheet in particular the serrations in the form of surfaces which are oriented either perpendicularly or parallel to the transport plane, furthermore means that high forces occur when the parts projecting behind the transport belts are folded over. This is particularly likely to result in further damage to the sheet material, especially with sheets in poor condition and at higher transport speeds.
  • DE-PS 27 29 968 describes such a device for smoothing overturned corners on paper documents.
  • the solution to this problem is seen in the fact that the document is guided into a slit-shaped gap, the clear width of which only slightly exceeds the thickness of the document and the inlet flank of which runs at an acute angle to the transport direction. It can be seen from the description of the invention that the shape of the flanks of the gap is intended to fold back the dog's ear while the document is being pulled through the gap.
  • the object of the invention is therefore to propose a belt transport system which has means with which bent parts of the sheet material are at least so far removed from the area of the belt without damaging it that jamming between the transport roller and belt is prevented.
  • the measures according to the invention can be used regardless of the condition of the sheet material. Since the stripping elements are assigned to the individual transport belts and, in special embodiments, are also effective on both sides of the belt, not only can bent corners, but also dog ears in the inner region of the edges, i. H. in the area of tears. This means that the stripping elements can also be used successfully in multi-belt systems. The function of the stripping elements is ensured even at high transport speeds without damaging the sheet material. In addition, the manufacture of the elements is extremely inexpensive and can also be subsequently integrated into existing transport systems.
  • Fig. 1 shows a belt transport system in section, in which a sheet material 1 is transported clamped between the transport belt 2.
  • the transport belts 2 are guided by transport rollers 3. These are in turn attached to a mounting plate 4.
  • Fig. 2 shows a part of the transport system shown in Fig. 1 in plan view.
  • the sheet material 1 to be transported is transferred in the transport direction 5 from the end transport rollers of the transport section 6 to the input transport rollers of the transport section 7.
  • the transport belts are deflected in the area of the respective pairs of transport rollers and returned to the respective opposite end of the respective transport section.
  • baffles are provided between the two transport sections 6 and 7 to ensure the clean transfer of the sheet material, the dog's ear clamped in by the transport belt 2 is either torn off, since the rest of the sheet material is forced in the planned transport direction, or the sheet material in the area the baffles are deformed in such a way that trouble-free onward transport is no longer possible (jam formation).
  • FIG. 3 shows a detail from a further variant of a belt transport system, in which the transport belts are replaced on one side by transport rollers 11 and guide plates 12. Similar to FIG. 2, the transport belt 2 on the transport roller 3 is also deflected in FIG. 3. The transported goods 1 are transported between the transport roller 11 and the transport belt 2 in the direction of arrow 5.
  • the sheet material 1 has a dog's ear 13 which is bent over the transport belt so far behind the transport belt 2 that it could be pinched between the roller and the belt when the deflection roller 3 is reached without additional measures.
  • the stripping element 14 is now provided.
  • Fig. 4 and Fig. 5 three such stripping elements are shown attached to a mounting plate 18.
  • the stripping elements 14 are each arranged symmetrically on the back of the belt 2 to the belt. They have sliding grooves 19, in which the belt runs as close as possible, and symmetrically to the longitudinal axis of the transport belt, two stripping surfaces 17 with which dog-ears can be pressed out of the rear clamping area of the belt on both sides of the belt.
  • FIG. 4 The arrangement shown in FIG. 4 is expediently positioned analogously to FIG. 3, shortly before the deflection roller 3, in such a way that the smallest possible distance remains between the deflection roller 3 and the stripping element, so that a dog's ear 13 does not find any possibility until the deflection roller 3 is reached, to slide behind the conveyor belt. Since the transport belt dips into the stripping element and is therefore partially covered by the stripping element in the critical area, direct contact between the transport belt and the dog's ear is effectively avoided.
  • Fig. 6 shows the stripping element according to the invention in different views. It can be seen that the stripping element viewed from the transport direction of the application (see FIG. 4) is conical-pointed, the stripping surfaces 17 and the sliding groove 19 extending from the tip 20 along the element.
  • the sliding groove 19 digs deeper and deeper into the stripping element starting from the tip 20, so that the belt is viewed deeper and deeper by the stripping element when viewed from the tip 20.
  • the stripping surfaces 17 have an approximately triangular basic shape on, which, relative to the center line of the conveyor belt 2, are arranged parallel to the conveyor belt at a slightly increasing acute angle.
  • the stripping surfaces 17 are formed by correspondingly bent stripping angles 23 which are mounted on a mounting plate 22.
  • the brackets 23 are designed such that they bend the donkey ears 13 around the transport belt while moving past the oblique edge upwards and thus also push the donkey ear out of the clamping area of the transport belt 2.
  • the stripping angles 23 only detect the donkey ears coming from one side of the belt.
  • a mode of operation which is bilateral per transport belt is possible by means of a corresponding symmetrical structure, i. H. in the sense of FIG. 6 by providing two opposite stripping surfaces per conveyor belt.
  • a stripping angle 23 constructed symmetrically in this way therefore offers the same possibilities as the stripping element 14 shown in FIG. 6.
