Definitions

  • the invention relates to a device for spreading or smoothing soft flexible flat material, in particular natural leather in the form of whole skins, according to the preamble of claim 1.
  • Natural leather is used extensively as a covering material for upholstered furniture, among other things, especially in the furniture industry.
  • the leather is printed during the manufacturing process. Since the natural leather follows the animal's body surface, a flat layer of skin required for printing is not readily given, even if it lies on a flat surface. The skins must therefore be spread out without wrinkles or smoothed or spread out or stretched immediately before printing.
  • the object of the invention thus consists in creating a spreading or smoothing device which is characterized by particularly intensive effectiveness and is particularly suitable for the production of a wrinkle-free state in the case of larger pieces of flat material, especially natural leather skins, in continuous operation.
  • the solution to this problem according to the invention is characterized in a device of the type mentioned at the outset by the features of claim 1.
  • the spreading or smoothing tools which are accordingly arranged on both sides of the longitudinal center line and act in opposite directions on the flat material with a brushing movement, not only progressively and transversely pull the material across the length of the flat material, but also cover practically the entire width of the material from the inside to progressive, slight contact and flexing deformation. As detailed tests have shown, this leads to an excellent degree of freedom from wrinkles even for very large material widths.
  • spreading or smoothing tools are provided with driven coating members movably mounted and driven along an orbit, at least one section of the orbit traversed by these coating members to the outside of the support surface running essentially parallel to the support surface.
  • the circumferential coating members can be arranged in sufficient number or with a small mutual distance and can be moved over the flat material at a sufficiently high speed so that there is a uniform and intensive stretching effect.
  • the spreading or smoothing device downstream processing station for example a printing or ironing or embossing station
  • a pair of inlet rollers on the inlet side which forms an inlet gusset tapering in the feed direction.
  • the coating members are then not restricted in their movement by parts of the processing station which overhang in the inlet area and can be brought close to the printing zone.
  • the coating members can engage in the feed zone of the rollers in the active zone of their orbit and can thus be guided particularly close to the pressure zone.
  • the spreading effect has the prerequisite that the streak members are only effective in their orbit in the direction from the longitudinal central axis to the outside. In principle, this can be achieved by lifting off the strikers during the return section of their orbital movement, for example with the aid of a gate control of a conventional type.
  • the one-sided direction of action is, however, particularly simple and therefore advantageous, according to a further development of the invention, in that the orbit is one of the contact surfaces receives inclined position, in the interest of the close-up already mentioned guide to the pressure zone or in the inlet gusset preferably a position inclined in the feed direction against the support surface.
  • rear and front transport rollers 3 and 4 are mounted on side parts 1 and 2 of a machine frame, via which a conveyor belt 6 runs in the direction of arrow 5 as a feed device to a downstream printing station.
  • the upper run of the conveyor belt 6 forms a Support surface for flat material pieces, not shown, here natural leather skins.
  • the rear transport roller which is located on the feed side I of the device, is assigned three feed rollers 7 for the application of such flat material pieces.
  • an inlet and printing roller 8 of this station cooperate.
  • the roller 8 rotates in the direction of the arrow 9, ie in the opposite direction to the transport roller 4.
  • an inking device 10 which interacts with the printing roller 8 is part of the printing station (see FIG. 3).
  • Spreading and smoothing tools are provided on both sides of the longitudinal center axis LL of the device, which have finger-shaped, driven moving members 12 which are movably mounted and driven on a closed orbit.
  • the latter are resiliently pivotably mounted on an endlessly circulating link chain 13 as a supporting member and each lie on their movement section (arrows 11) directed outward from the longitudinal central axis LL (arrows 11) with a predetermined contact pressure on a conveyor belt 6 carried in the feed direction (arrow 5) by the support surface (arrow 5) shown) piece of material and stretch this by opposing brushing and flexing action transversely to the feed direction.
  • the level of the link chain 13 or the orbit is arranged so that it slopes downward in the feed direction against the support surface of the conveyor belt 6, so that the coating links 12 are automatically lifted off the flat material on their inward-moving section.
  • Each link chain 13 runs over guide or drive sprockets 14, which are each supported at the corner points of a guide frame 15, which in turn consists of longitudinal members 16, 17 and cross members 18, 19 and with its frame level determines the orbital plane of the coating members 12.
  • a drive unit 20 for the associated link chain, which acts on one of the chain wheels 14, is arranged on each guide frame 15.
  • Each guide frame 15 is fastened by a lifting device 21, which has a cylinder-piston unit 22, to a crossmember 23 which extends across the conveyor belt 6 between the side parts 1 and 2 of the machine frame.
  • a lifting device 21 which has a cylinder-piston unit 22, to a crossmember 23 which extends across the conveyor belt 6 between the side parts 1 and 2 of the machine frame.
  • the two guide frames and thus the orbital planes of the coating members are arranged inclined to the flat material support surface in the manner already mentioned.
  • the guide frame 15 and thus in each case the entire spreading or smoothing tool are also pivotally mounted on the crossmember 23 by means of the lifting device 21, so that the circumferential plane inclination angle and thus also the angle of attack of the coating members within their orbital effective section, that is to say in the respective lower run the link chain 13, with respect to the flat material contact surface is cash.
  • the elongated coating members 12 can be brought into a position essentially parallel to the bearing surface within their effective orbital section and thus into a system with the flat material that extends over their entire length.
  • the feed device is guided by a conveyor belt 60 with a contact surface AF on the upper run, which is guided up to just before the inlet gusset EZ of the rollers 4 and 8 forms.
  • the contact surface moved in the direction of arrow 5 leads to a flat material piece FM, indicated by a dot-dash line, to the inlet gusset EZ, where a spreading tool WZ1 with bristle-shaped coating members 120 rotating about an inclined axis XX is arranged.
  • the latter rotate under the action of a drive unit AT in an orbit plane UE which is inclined towards the support surface AF in the feed direction (arrow 5) and engage in the lower region of the orbit transversely to the feed direction on the flat material, namely, as not shown here, on both silks of the longitudinal central axis in each case in the direction of the side edges of the support surface or the conveyor belt 60.
  • the brush of the spreading tool brings about a relatively gentle stretching of the flat material which is gentle on the surface. Otherwise, this embodiment is characterized by advantageous simplicity.
  • the desired engagement of the coating members in the inlet gusset of the downstream rollers can also be achieved here with a simple construction of the device.
  • FIG. 5 shows, in conjunction with a feed device, namely a conveyor belt 6, and a roller arrangement 4, 8 according to FIG. 1, a spreading tool WZ2 in the form of an endlessly rotating brush belt via deflection and drive rollers W transverse to the feed direction (arrow 5) with bristle coating members 220 running in vertical planes.
  • This design is also characterized by great structural simplicity and correspondingly low construction costs, as well as by a large-area, soft attack of the spreading forces on the flat material FM.
  • the intervention in the inlet gusset of the rollers 4, 8 is, however, only possible to a limited extent here.
