  • the set of these profiling heads is a set of profiling heads that is adapted to a specific profile.
  • machines have been proposed comprising the plurality of sets of profiling heads that can be changed by lateral translation parallel to the profiling line.
  • profiling profilers with drawers allow a quick change of sets of profiling heads but have the disadvantage of having a very large footprint. Indeed, it is necessary to provide next to the profiling line itself a space for receiving the profiling heads that are not used and a space for receiving handling means profiling heads.
  • the document JP-A-59159224 discloses a roll forming machine for profiling a sheet comprising a plurality of profiling heads for changing sets of profiling heads by rotation of a turret. This type of profiler has a large footprint.
  • the object of the present invention is to overcome this disadvantage by proposing a profiling machine which makes it possible to make rapid changes of sets of profiling heads, while having a very small footprint.

  • Each of the profiling heads belongs to a particular set of profiling heads which is intended to form a particular profile.
  • These forming heads each belonging to a particular game are mobile as will be seen later between service positions and erased positions, which allows to put into operation or out of service each profiling head sets and therefore to pass from one set of profiling heads to another set of profiling heads.
  • the module generally marked by 2 comprises a first group 3A of pairs 31A and 32A profiling heads 311A and 312A for the first pair 31A and 321A and 322A for the second pair 32A.
  • the second group of pairs of profiling heads 3B similarly comprises a first pair 31B of profiling heads and a second pair 32B of profiling heads which will not be described in more detail since they are quite similar to the pairs previous profiling heads.
  • each profiling head comprises a pair of profiling shafts generally identified by 7 and consisting of two shafts 71A and 72B parallel to each other.
  • Each shaft carries rollers 72A and 72B respectively and against rollers 73A and 73B respectively, separated by spacers 74A and 74B respectively.

  • the profiling head 321A of the pair 32A is in this service position
  • the second profiling head 322A of the same pair 32A is in the second erasing position E2 located below the profiling plane P.
  • the two profiling heads 311A and 312A of the second pair 31A of the profiling head are in the first erasing positions E1 located below the plane P, and are at the same height.
  • profiling heads By moving the profiling heads parallel to themselves perpendicularly to the profiling plane, it is possible to put into service one of the four profiling heads of the first set 3A of two pairs. profiling heads.
  • one of the heads of the second group 3B of profiling head pair can be put into service, the other profiling heads being erased and thus allowing the sheet to pass only between the profiling heads which are in position. service.
  • the two profiling heads of the groups of the pair of profiling heads that are not in service are in a first erasure position in which they can serve as support for the sheet being profiled.
  • This number of profiles that can be achieved corresponds to the distance between two successive profiling heads that are in use. Indeed, the distance between two profiling heads should not be too great to prevent too much length of sheet is not supported. Conversely, this distance should not be too short either. As a result, the distance between two successive heads which may for example be between 500 mm and 1 m possibly makes it possible to interpose one or three profiling heads between two profiling heads in use. This leads, in one case to two separate games, or two distinct profiles and, in the other, to four separate games, four profiles.
  • This actuation system comprises a chain 314 whose ends are fixed on the one hand to the head profiling 311 and secondly to the profiling head 312, which wraps around a gear 315 carried by a shaft 318 on which is mounted a gear wheel 316 which cooperates with a rack 317.
  • the rack 317 is actuated and moved in one direction or the other, it drives the gear wheel 316 which through the shaft 318 drives the gear 315.
  • the rotation of the gear 315 moves the chain 314 by raising or lowering the gear 314. down the two profiling heads 311 and 312, one of the heads up while the other descends and vice versa.
  • the rack 317 is driven by a motorized drive means 319 visible on the figure 5 but which is not necessarily provided on the module 2 shown.
  • the shaft 318 which extends over the width of the profiling machine, parallel to the profiling heads, carries two toothed wheels 315 each driving a chain 314.
  • the two chains 314 are arranged on either side of the line of passage of the sheets to be profiled.
  • the toothed wheel 316 'driven by the rack 317' which is intended to drive the second pair of profiling heads of the group of profiling heads considered.
  • the rack 317 drives the gears which make it possible to raise and lower the profiling heads of a first pair 31A of the first group 3A and a first pair 31B of the second group 3B of profiling heads and the second pair rack 317 'can separately drive the gears which can handle the second pairs 32A and 32B groups 3A and 3B.
  • the racks 317, 317 ' are driven by means 319, 319' respectively, comprising a motor and a gear wheel, which the skilled person knows how to achieve.
  • the profiling head 311 which has two shafts 71A and 71B comprises a gear motor 3113 for driving the shafts 71A and 71B.
  • This gear motor 3113 is connected by an electric cable 3114 to an electrical control cabinet 3115.
  • the cable 3114 is of sufficient length to absorb the effects of vertical displacements of the profiling head 311.
  • This figure also shows locking means in the service position of the profiling head.
  • These locking means are on the one hand shims 41 and 42 disposed on the uprights 4 on either side of the passage of the profiling head and on the other hand rollers 3111 and 3112 which are disposed on the outer faces 3110 and 3110 'of the profiling head 311.
  • the rollers 3111 which comprise a peripheral groove and the shims 41, intended to cooperate with the rollers 3111, comprise a ridge of complementary shape to that of the groove of the rollers 3111 so as to be able to penetrate inside the groove when the forming head arrives in the service position and thus block the position of the profiling head both in a direction parallel to the axis of rotation of the cylinders 71 of the profiling head and secondly in a perpendicular direction.
  • the cylindrical rollers 3112 disposed on the outer face 3110 'of the profiling head located on the other side of the line of passage of the profile sheet cooperate with shims 42 planes.
  • the profiling head when the profiling head is in the service position, it is wedged by the wedges 41 and shims 42 in a precisely defined position, which ensures a good adjustment of the profiling head.
  • the rollers 3111 and 3112 are mounted on eccentrics which make it possible to move the rollers from a jamming position to a relaxed position and vice versa.
  • the profiling machine comprises a plurality of profiling modules, such as those which have just been described and which are arranged one after the other. These profiling modules, once assembled, are traversed over their entire length by racks, a first rack disposed on one side of the profiling machine is intended to handle a first set of pair of profiling heads and, on the other side, on the other edge of the profiling machine, a second rack for moving the second set of pairs of profiling heads.
  • the first series of pairs of profiling heads constitute two sets of profiling heads making it possible to produce two profiles
  • the second series constitutes two other games making it possible to produce two other profiles.
  • this machine which has the advantage of having a bulk width limited as it does not extend beyond the width that is strictly necessary to achieve a profiling line of a strip or sheet scrolling , also has the advantage of making it possible to make very rapid changes of sets of profiling heads, for example in less than 30 seconds, which makes it possible to substantially increase the productivity of the machine.
  • it can be moved and mounted very quickly since it is sufficient to prepare the series of independent modules with four pairs of profiling heads. These modules can be moved separately and installed individually, then secured and finally electrically connected to a control system, which allows to easily mount the profileuse (16 hours with 4 operators).
  • this machine has a cost of manufacturing and installation that can be reduced by 30 to 35% and disassembly and assembly operations to change sites are extremely fast.
  • a slide profiling machine as just described has compared with a profileuse with drawers in which the profiling heads are moved laterally to the advantages of having a floor area divided by 4, and of allow module manufacturing with very simple assemblies by four screws for the frames, and two for the racks, with electrical connections by pin plugs very easy to put in place or remove.
  • the assembly can be performed within a few days by two technicians, which leads to divide by 10 installation installation costs.
  • the machine which has just been described consists of modules each comprising four pairs of profiling heads grouped into two groups. However, those skilled in the art will understand that other arrangements are possible: the modules may comprise a greater or lesser number of pairs of profiling heads, the modules of the same machine may not all have the same number of profiling heads, the machine can also be in one piece.
