  • the second conveying line 22 denotes a second conveying line, for example of the roller type, arranged for example immediately downstream of the cutting machine 20.
  • the second conveying line 22 is provided with a stop 23 for cutting to size, preferably movable in both senses in a direction parallel to the first feeding direction A1.

  • feeding is interrupted and cutting is performed, resulting in an intermediate layer S3 which lies on the second conveying line 22.
  • the first series of evacuation belts 24a moves upwards and separates the intermediate layer S3 from the second conveying line 22, moving it out of the volume of said second conveying line. Then the first series of evacuation belts 24a moves downwards, returning into the initial position so that the second conveying line 22 is able to receive a new layer.

At least one of the two uprights is movable in a vertical direction with respect to the other one so that, if the projecting cross members 40b are aligned in the same horizontal plane, the rack defines as many support surfaces 42 as there are projecting cross members 40b for each upright 40a, whereas if the two series of projecting cross members 40b are staggered, the rack defines a number of support surfaces 42 twice the number of projecting cross members for each upright 40a.
  • FIG. 15 An example of staggered racks is also illustrated in Figure 15, in which the right-hand oven has the two uprights staggered in the vertical direction with respect to the left-hand oven. This allows double the number of support surfaces to be obtained, arranged at a smaller distance from each other.
  • a door 43 which opens and closes off access into the oven is envisaged.

  • the transfer device 92 and in particular the framework 96 moves upwards, being displaced in the direction Z, therefore raising the layers.
  • a further displacement of the trolley 94 along the axis X brings the layers opposite the conveying line 88; the framework 96 moves downwards so that the layer on the surface 72b is positioned on said conveying line.
  • the framework 96 moves down further until the layer of the surface 72c is positioned. Lowering of the framework continues until all the layers of the raised surfaces are resting on the conveying line 88.
  • the plant 10 comprises a packaging area 100 able to receive the layers for example supplied by the conveying lines 86, 88.
  • the packaging area 100 corresponds substantially to the detail XIII in Figure 1 and is further illustrated in Figures 13 and 14.
  • the packaging area 100 comprises at least one packaging station.
  • the example illustrated envisages two packaging stations 102, 104 in which the operation is performed manually.
  • the conveying lines 86, 88 on which the strips are supplied have the possibility of stopping at one of the above mentioned packaging stations.
  • transverse conveyor belts which are operationally connected to raising means, not shown, which raise or lower the transverse conveyor belts with respect to the conveying lines 86, 88.
  • These transverse conveyor belts are able to transfer selectively the layers from the conveying lines 86, 88 to the packaging stations 102, 104.
  • the conveyor belts 106 transfer the layers from the conveying line 88 to the packaging stations
  • the conveyor belts 107 transfer the layers from the conveying line 86 to the conveying line 88, defining means for transfer of a layer of sections between two conveying lines arranged alongside each other.
  • the conveyor belts 107 define an evacuation line able to receive the layer and move it in an evacuation direction arranged transversely with respect to the two conveying lines.
  • the layers advance from the preceding area, for example the by-pass area, to the packaging area, travelling on the conveying lines 86, 88. Both the layers which travel along the conveying line 88 and those which travel along the conveying line 86 are able to stop selectively in front of one of the packaging stations 102, 104.
  • the transverse belts 106 move upwards and raise the layer, transferring it directly to the packaging station where the operator may package the required sections.
  • the conveyor belts 106 move downwards, allowing the possibility for another layer to advance along the respective conveying line and stop at one of the packaging stations.
  • the transverse belts 107 move upwards and raise the layer, transferring it to the conveying line 88 where they are picked up by the conveyor belts 106 so as to be finally transferred to the packaging station where the operator is able to package the required sections.
  • both the transverse belts 106 and the transverse belts 107 move downwards, allowing the possibility for another layer to advance along the respective conveying line and stop at one of the packaging stations.
  • a further advantage of the plant according to the invention consists in its unusual structural simplicity which allows it to be produced at a very low cost with maximum automation of the individual steps.
  • a layer treatment zone which is very versatile and compact and which may be modified modularly in order to satisfy different production requirements.
  • the different working areas illustrated in Figure 1 may also be provided individually inside a plant in particular for the production of metal sections.
  • FIGS 15-19 illustrate a possible embodiment of the trolley 44 or trolley 58.
  • 108 denotes a structure formed by uprights 108a and cross members 108b. Wheels 110 mounted on the bottom end of the uprights are able to travel on bottom rails 45 and are operationally connected to actuating means 112.
  • FIG. 114 denotes cross members movable in a vertical direction with respect to the structure 108 and defining a substantially horizontal plane.
  • Figure 15 illustrates a cross member 114 both in a bottom position and in a high position.
  • the movable cross members 114 are integrally joined to chains 116 (only partially illustrated in Figures 15 and 16) wound around toothed pulleys 118, one of which is operationally connected to actuating means 120.
  • the support surface 44a of the trolley 44 is defined by a series of rollers 122a and 122b.
  • the first and last rollers of the trolley 44 which are denoted by the reference number 122a, are mounted idle, whereas the central rollers, denoted by the reference number 122b, are made to rotate preferably by means of a single drive system which transmits the movement to the rollers 122b by means of a chain drive 124.
  • 126 denotes elements for supporting the rollers 122a and 122b in turn supported by additional cross members 128.
  • 130 denotes means for raising and lowering the additional cross members 128 operationally situated in between the cross members 128 and the cross members 114.
  • the means 130 comprise levers 132 having ends hinged respectively with the movable cross member 114 and the additional cross member 128.
  • one or more rollers 122b are alternated with the movable arms 46.
  • a movable arm 46 is situated between every two rollers 122b.
  • a movable arm 46 comprises a section 134 sliding with respect to a support 136 mounted on the movable cross member 114.
  • Each end of the movable arm 46 comprises a tooth 138 which projects transversely with respect to the extension of the arm 46.
  • the movable arm 46 comprises roller wheels 140 mounted idle on said arm and interacting with the support 136 so that the movable arm 46 is slidable.
  • the movable arm 46 comprises at least one pair of roller wheels 140 arranged on opposite sides of a portion of the support 136.
  • the means 142 denotes means for displacing the movable arm 46 with respect to the support 136, in both directions with respect to the structure 108.
  • the means 142 comprise a chain drive mounted on the support 136 and operationally connected to the movable arm 46.
