Definitions

  • the invention relates to a device for processing leather, furs, furs and similar materials according to the preamble of claim 1 or 3 or 4 or 7.
  • Such pass-through devices include known for leather drying purposes. They preferably work in continuous cycle operation, but are also fundamentally suitable for continuous operation, and are characterized by high throughput in relation to the processed leather surface.
  • a first object of the invention is therefore the creation of a construction for pass-through devices of the present type which, given a given working path length, allows a reduced space requirement without impairing the trouble-free passage of the leather by the design of the working path or the arrangement of the work stations.
  • the solution to this problem according to the invention is determined by the features of claim 1 or 3 or 4 or 7.
  • the solution according to claim 1 generally favors a space-saving design in the area of drying stations, which are known to generally require treatment of the leather on both sides (e.g. heating on one side and suction on the other side).
  • the guiding of the leather between the conveyor belt and the gas-permeable or highly heat-conducting auxiliary belt provides an optimal position securing and thus a trouble-free passage without obstructing the drying process, regardless of the position of the drying station.
  • the arrangement of the station can therefore be freely chosen according to high utilization of space and, if necessary, functional.
  • the solution according to claim 7 is particularly suitable in combination with that according to claim 4, but in principle also independently of it.
  • the machining means heatating, suction, etc.
  • it allows the machining means (heating, suction, etc.) to be attacked, possibly preferred or also necessary, directly on the leather and, on the other hand, the advantage of the safe leather guidance in the other sections of the continuous path, particularly on the Redirections.
  • the solutions mentioned each offer significant progress in themselves, but functional advantages combine to bring about particular advantages.
  • FIG. 1 illustrates, in the form of a side view, a cycle flow device according to the invention.
  • the continuous path for pieces of leather L to be processed is formed by a conveyor belt TB which rotates endlessly over drive or deflection rollers 1, 2.
  • a lay-up station AST, a combined stretch-drying station STS and a first drying station TRS1 are arranged on the upper or forward section AI of this continuous path.
  • the aforementioned work stations are of a type known per se and are therefore not shown in detail in detail.
  • Pieces of leather L spread out at the lay-up station AST are successively subjected to the corresponding operations, preferably in cyclical operation with the conveyor belt at rest during the operations. Between the rest or work cycles, the leather pieces are conveyed at high speed from the lay-up station to the stretch-drying station or from there to the drying station.
  • a membrane M spanning the leather forms an airtight gap with the contact surface, each of which accommodates one or more pieces of leather and which is connected to an ASV suction device. The negative pressure created by the suction in the gap space causes the membrane to be pressed evenly against the material, thus creating a frictional frictional connection.
  • the membrane area is increased by a predetermined amount, the pressed leather being stretched between the friction-effective underside of the membrane and the conveyor belt, which is made of sliding-friendly material, by being carried along on the membrane.
  • the material to support the stretching process is heated from below via the heat-conducting material of the conveyor belt by a heating device HZV distributed over a large area. The heating is measured so that the leather moisture is evaporated. The steam formed in this way is discharged through the suction device and suction openings correspondingly distributed over the membrane surface, so that there is a predrying effect.
  • a first main drying step then follows in the station TRS1, which is designed in a manner known per se as a vacuum dryer with a heating device HZV on the underside and an ASV suction device on the top.
  • the leather is heated through the highly heat-conducting conveyor belt.
  • An essential element of the embodiment of the invention shown is an endlessly circulating auxiliary belt HB which interacts with the conveyor belt TB and is at least partially gas-permeable and / or highly heat-conductive, which is guided over additional deflection or drive rollers, which are not described in any more detail.
  • the functionally essential part of this auxiliary belt extends from the exit of the station TRS1 along the conveyor belt and in abutment thereon over the deflection section ULA of the continuous path, ie over the circumference of the deflecting roller 2, and also along the underflow or return section A2 of the continuous path bi to the underside of the drive roller 1 of the conveyor belt located at the entrance to the device.
  • the leather is guided between the conveyor belt and the auxiliary belt or with light pressure on both sides and is therefore absolutely safe against wrinkling. This is particularly important in the deflection area.
  • the leather transported in the return section to the entrance area arrives at a take-off station ABS with take-off conveyor belt AB via guide elements LE, which ensure a smooth transfer of the leather.
  • a particularly compact and space-saving design now results from the fact that a further work station, here for example a second drying station TRS2, is arranged in the return section A2. If necessary, several such can be advantageous additional workstations can be provided in the return section.
  • a further work station here for example a second drying station TRS2
  • Utilization for additional workstations is particularly suitable for regions of the continuous path that run horizontally or at an acute angle to the horizontal. This results in an upper section of the conveyor belt and a lower section of the auxiliary belt, which favors a smooth leather run. In principle, however, because the leather is guided on both sides between the transport and auxiliary ban, a corresponding arrangement is also advantageously possible for steep or vertical sections of the leather passageway.
  • auxiliary belt is adapted to the requirements of the workstations.
  • an at least partially or sectionally gas-permeable and / or highly heat-conducting auxiliary belt is used.
  • the suction device ASV of the station TRS2 is also arranged on the underside of the pass-through path.
  • the auxiliary band is designed to be sufficiently gas-permeable, for example by means of a corresponding porosity or a large number of openings or by means of a lattice-like training.
  • the heat for drying is provided here by the highly heat-conducting conveyor belt. If necessary, an inverted arrangement of the heating and suction device with a correspondingly inverted design of the conveyor and auxiliary belt can also be considered. However, a highly heat-conducting conveyor belt is often provided in any case for devices of the present type, so that the exemplary embodiment shown is preferably used.
  • the main working area of another embodiment of the invention is shown in a side view in FIG.
  • This main area comprises a large number of drying stations TRS connected in series with heating device HZV and suction device ASV.
  • an input or preprocessing area which precedes the main area at the point marked X-X in FIG. 2 and which is easily understandable e.g. can be designed in the manner of the flow device according to Fig.l.
  • a meandering course with at least three working sections AS that run at least partially parallel or at an acute angle to one another and deflection sections US arranged between them is essential for the design of the leather continuous path in the main work area. At least a part of these work sections - in the example all work sections - At least one - in the example one - workstation is assigned to each.
  • a circumferential auxiliary belt HB is provided, which extends along the leather continuous path in the entire main work area.
  • the leather is guided here in all working and deflecting sections, that is to say also lying within the drying stations TRS between the conveyor belt and auxiliary belt.
  • Each of these drying stations in turn comprises a heating device HZV and a suction device ASV - arranged opposite each other on both sides of the continuous path.
  • the conveyor belt is highly heat-conducting and the auxiliary belt is gas-permeable. Accordingly, the heating device is arranged on the side of the conveyor belt and the suction device on the side of the auxiliary belt.
  • the heating device is fixed to the frame and the suction device is adjustable according to the double arrows entered between a working position with contact with the auxiliary belt and a raised rest position.
  • the suction device assumes its rest position during the transport movement.
  • auxiliary belts HB arranged on the outside on the deflection sections US of the leather pass-through path which are convex with respect to the continuous leather are provided for safe deflection guidance of the leather, while the pass-through path in the region of the work stations TRS is free of auxiliary belts, that is to say is formed only by the conveyor belt TB.
  • Such an embodiment is particularly advantageous, for example, if - for reasons of accessibility of the reader in the work area - a continuous auxiliary belt is not desired.
  • a longitudinal guide section LFA which conveys the leather L now located on the underside of the conveyor belt TB to the next following deflection, is connected at the outlet end of one of two successive deflection sections US within the orbit of the auxiliary belt HB in question.
  • the longitudinal guide section LFA is a wedge-shaped deflection ULE provided for the auxiliary belt at Auslauende that edge into a deflecting UK runs with a small radius. This deflection edge can be arranged comparatively far reaching into the entry angle between the conveyor belt and deflection roller, so that an only narrow gap between the successive guide elements and thus a reliable transfer of the leather is achieved.
  • a knife-like lifting element AHE which is in contact with the circumference of the deflecting roller and is known per se, is provided on the outlet side of the deflection point preceding each work station. This prevents the leather from sticking to the guide roller and ensures trouble-free entry into the work station.
  • a continuous auxiliary belt HB which interacts with the conveyor belt TB, is again provided for guiding the leather.
  • the auxiliary belt is, however, at a distance from the leather pass-through path and on the back of a part that is operatively connected to the leather, here e.g. a suction device ASV, the workstation.
