Definitions

  • the object of the invention relates in particular to the technical sector of the methods, means and devices for manufacturing, assembling and orderly grouping of various assemblies produced from a support strip and at least one component which is generally a flexible sheet, but not exclusively, these sets considered in continuity or separated, being susce p patible of applications, many and varied uses, for example, the manufacture of forms, office machinery diet, "printers "combined with computer processing equipment ...
  • component we generally mean one or more concerned sheets of paper, plastic or other flexible material, which are pre-printed or not. It is not excluded that the component is a semi-rigid plate, printed or not.
  • the two continuous support strips are flexible or semi-rigid strips, generally made of paper, without excluding any other souble material. or semi-rigid, suitable (plastic material, etc.).
  • the two support strips have on the edge, in a manner known per se, a "Caroll" type perforating liana intended for driving said strips and their assemblies, on the processing and use machines.
  • the method is remarkable in that two support bands are used. of small width, instead of a single strip of width necessarily greater than the component, these support strips having transverse lines of inverted pre-folding; the support bands are pulled by a gripping means simultaneously with a component located at the base of a stack, so that the component is superimposed on the support bands with the lateral medium of the support bands in correspondence with the lateral edges the component which has been previously punctually heated; pressure is exerted between the support strips and the component, by pulling the component and passing over rollers; this pressure combined with the heat absorbed by the component operating the bonding of the component on the support strips having, for this purpose, bonding means; the support strips are folded on the pre-folding lines and the component extracted from the eye is deposited and fixed in the accordion nlis.
  • the means for implementing the method successively comprise a deflection roller.
  • pairs of pressers for applying the component extract against the pairs of support bands, and an orderly receiving tray for the bands support-component.
  • the assemblies produced according to this process are constituted by components comprising at least one and generally several sheets assembled at the head to form bundles, and by drive bands or support bands with longitudinal perforations assembled with the edges from the bottom sheet of the components, over the entire length thereof, the perforations of the strips lying beyond the edges of the bottom sheet; the drive belts with transverse lines of inverted pre-folding and the lower sheets of the components also profiled transversely, are presented after assembly of the bands and the components, in the form of an accordion pile, while the leaf or leaves of the components, other that the lower sheet, are unfolded, that is to say flat and extend substantially beyond the transverse lines of pre-folding of the lower sheets and the drive belts.
  • the support bands (la) are cut from pairs of flange coils (3) mounted on a hub (18) clamped on a support shaft (2) fitted with a permanent brake.
  • the connection between coil and hub is ensured by a spring (19) of constant tension of the support bands.
  • the support strips are also provided at the edge of a line of longitudinal perforations (1c) intended for training on the processing and use machine. Alternatively, the perforations can be performed on the machine itself. These perforation lines are known as "Caroll perforation".
  • the cut support strips pass first on a fixed deflection roller (4), then between two complementary shapes (5a and 5b) intended to form inverted pre-folding lines (1d), FIG. 5; these two complementary forms are controlled by an electromagnet (10) and are of the male V-type - female V-type for example.
  • the support strips (1a) having passed through the device (5) are then wound on a second roller (6) adjustable in position. Said strips again pass through a device (5) superimposed on the parts of the first pass strips. Pre-folding is thus carried out on two thicknesses at the same time.
  • the device (5) is adjustable in position in order to adjust the position of the pre-folds (1d) relative to the component (1b).
  • rollers (9) adjustable in spacing and provided with spikes angularly distributed so that they correspond to the pitch of the holes making up the line of longitudinal perforations, these rollers are kinematically linked to a cylinder rotatable by means of a gear (24); the support strips are therefore perfectly positioned relative to the rotary cylinder.
  • the rotary cylinder (8) covered with a slightly flexible material (rubber for example), is pierced with holes and mounted on a shaft (36) not rotating but oscillating.
  • This shaft acts as both a pivot axis and an air distributor, with a suction part adjustable by translation of two sealed tubes (26a), while the blowing part, not adjustable in width, is connected to air supply tubes (26b).
  • the support strips and the component are therefore pulled together and in the same direction, one by winding on the cylinder, the other by pulling the cylinder (8) in the suction phase.
  • the rotary cylinder (8) must be able to rotate periodically in order to give successive advances corresponding to the length of a component (1b).
  • the movement is then transmitted to the cylinder by a pair of gears (27) and (28) whose ratio is equal to one, passing through an intermediate gear (17).
  • the clutch and braking action is controlled by a photoelectric cell (34) which detects a certain number of graduations of a disc (29), graduations which rotate at the same time as the cylinder and which correspond to advances. useful bands-support-component.
  • This number of graduations is totaled in an electronic counter-totalizer (32) which stops the cylinder net according to the figure displayed on this device.
  • An electronic timer (33) then allows the necessary stop time for the cylinder (8) to vacuum the component. Then the cycle begins again.
  • the rate depends on the time delay.
  • the angular speed of the cylinder depends on the speed of the engine.
  • connecting rods (11), articulated on the shaft (17a), are resiliently recalled by a spring (46) against a stop (47), in the front position, when the action on the brake of the pinion (40).
  • the component suction device is now described.
  • the cylinder (37) is tightly closed at both ends ends by plugs (48) and the hollow shaft (44) communicates with the interior of the cylinder by multiple orifices (44a).
  • the hollow shaft made of material which does not conduct magnetism, are tightly mounted and spaced apart electromagnets (49) which are supplied individually to act on a variable number of micro-valves (50) equipping the multiple orifices (37b) of the cylinder, figures 7, 8, 9.
  • the micro-valves (50) are composed of a curved elastic blade (5Oa), one branch of which is fixed on the internal wall of the cylinder (37) with its orifice (5Ob) in agreement with an orifice (37b) of the cylinder, while on the other branch, is fixed an elastomer block (50c) which, at rest, closes the orifice (37b).
  • the branch carrying the shutter block is attracted and thus allows the passage of the suction air coming from the hollow shaft.
  • the components are stacked in the magazine with their head part (assembly side between the sheets of the component) on the side of a suction device (12) creating a vacuum between the co-components, in order to avoid defects of scrolling during the aspiration of the components when these form a bundle.
  • the component is pressed on the support strips using two pressure rollers (15), this in order to adhere to the support strips the half length of component, on the side of its head portion; the component was previously heated only over its half length, on the head part side.
  • the aspiration of the component located under the pile is carried out by the rotary cylinder provided with aspiration holes, the contact line between the cylinder and the component is located in this first phase, towards the end of the foot portion of the component. (about five millimeters), in order to draw it to its extreme part, without detaching it from the other components.
  • the lower components of the stack adhere to each other by creating a vacuum between the components (over a height of about ten millimeters), this thanks to the suction element (12).
  • the component is sucked in by the rotary cylinder through an appropriate opening in the magazine (7).
  • the cylinder (8) is driven by a rotational movement programmed by the totalizing counter (32), this, depending on the length of the component.
  • the suction cylinder pulls simultaneously on the support strips and the component.
  • the non-rotating but oscillating shaft (36) mounted on the two connecting rods (11) can oscillate freely without mechanical connection;
  • the rotary cylinder (8) mounted on the shaft (36) is, on the other hand, kinematically connected to the system of successive rotations, by the gears (28), (17), (27).
  • This oscillation brings about a displacement of the contact line, cylinder-component towards the lower component which is thus wound on the cylinder (8) and is detached from the stack; the other lower components being glued together by vacuum, only the first component being peeled off.
  • the top sheet of the component a little longer than the other sheets (for example, three millimeters).
  • Heating resistors (13) placed against the stack of components are used both as a guide for placing the components and as a spot heating of the edge of the components.
  • the magazine (7) is preferably inclined 30 ° relative to the vertical and in the direction of advance of the support strip, in order to transfer part of the weight of the stack of components to the wall (14 ), thus avoiding pressing too hard on the extracting component.
  • the assemblies obtained according to this method and these means illustrated in FIGS. 1 to 4, include, as can be seen in FIG. 5.
  • the tray (51) is equipped with an automatic lowering device, in order to maintain the top of the stack at the same height.
  • This device can be constituted by any means such as a ratchet brake (52) cooperating by pinion (53) with a rack (54) fixed on an upright (55) of the machine, FIG. 6, or alternatively, by a device such as described above in the embodiment according to FIGS. 1 to 4.
  • the assembly of the components and the drive strips is effected by heating the strips before or during the separation operation of the components, when the strips are coated with a hot-melt or hot-melt adhesive.
  • FIGS. 14, 15 and 16 illustrate the assemblies obtained according to the method and the means described above.
  • FIGS. 15 and 16 we see the assemblies presented flat with the foot parts of the free sheets of the components slightly overlapping on the head parts of the preceding components, in order to facilitate passage through the machines for treating the assemblies (according to arrow f ).
