Definitions

  • the present invention relates to a machine for folding the planes and more precisely a machine for folding according to the so-called “single hinged wallet folding" folding, hereinafter referred to as wallet folding, a plane or similar surface already folded in accordion.
  • French patent N ° 71 00338 which explains the problem to be solved.
  • the plan or similar surface is first folded in alternating folds so as to obtain a strip folded in accordion, the width of a fold being equal to one of the sides of the format, in general the short side. This operation can be carried out in a correct manner with the machine described with reference to FIG. 1 of French patent No. 71 00338. It is then necessary to carry out a "portfolio" folding to fold the band folded in first for itself.
  • the downward movement of the blade 6 is controlled by the abutment of the front end of the strip folded in accordion against a stop 11 located at a distance 2L from the blade, L being the length of the side of the format to be produced, this stop controlling contacts under the action of the pushing of the strip.
  • the strip thus folded for the first time is received on a second table 12 similar to the first but whose stop 13 is only at a distance L from the blade 14, which ensures the second folding by engagement of the strip already folded for the first time. through a slot 15 between pinch rollers 1 6 and 17 cooperating with deflection rollers 18 and 19 which direct the plane thus folded in the portfolio on a conveyor belt for evacuation 20.
  • the object of the present invention is to remedy these drawbacks and its subject is a machine for portfolio folding to a determined format of a strip of length greater than twice the length of the format in the direction of the length of this strip.
  • the strip from its introduction to the first folding blade, always flows in the same direction, being pulled and not pushed. It is therefore possible to guide it positively, if necessary, between belts or pressing cylinders as close as possible to the point of formation of the fold.
  • the length of strip, the detection of which determines the fixing of the fold, is pulled and not pushed, which avoids all the disadvantages of the prior machine.
  • the double folding is carried out in two substantially perpendicular directions, the strip brought horizontally and folded a first time being moved vertically then folded a second time to then be moved substantially horizontally according to a direction opposite to that in which it is brought to the unfolded state.
  • This characteristic makes it possible to ensure the entire portfolio folding with the rear part of the strip corresponding to the folding format, that is to say in practice the cartridge, in guide contact with a positively driven continuous conveyor element.
  • This continuous conveyor element can be constituted by an endless belt or belts, guided on rollers or pulleys or by multiple rollers arranged in the same layout.
  • Said oscillating drive element may consist of a roller or a belt or endless belts. It can be positively driven or be mounted free.
  • the machine according to the invention comprises a feed surface of which at least the part adjacent to the line of action of the folding blade is constituted by a positive drive element of the strip to be folded with at least one guide element holding said strip in abutment the positive drive element, a folding blade movable in a direction substantially perpendicular to that of the supply surface to engage the fold of the strip to be folded formed by this blade, in the above direction, between an element positive drive element and a guide element holding the folded strip in abutment against the latter positive drive element, a second folding blade movable in a direction substantially parallel to that of the feed surface to engage the fold of the strip formed by this blade, in the above direction, between a positive drive element and a guide element holding the folded strip in abutment against the latter positive drive element and evacuation means one of the folded strip in the portfolio thus obtained.
  • the machine in the embodiment illustrated in Figures 2 to 4 comprises a feed table 21 which could be constituted by an endless belt or a sheet of parallel endless belts 3. Rollers 22 driven ensure the progression of the band. Pressure elements, rollers or endless strip (not shown) could keep the strip 23 to be folded resting on the table, the strip 23 moving in the direction of the arrow F.
  • the main conveyor element in contact with which the surface of the cartridge is in contact during all of the folding is constituted by an endless band 24 guided on rollers 25.
  • Said band comprises a strand 24a which extends the table 21, then, after a quarter turn around the cylinder 25a, a substantially vertical strand 24b then, after a quarter turn around a cylinder 25b, a substantially horizontal strand 24c and finally after passing around a cylinder 25c a strand back towards the strand 24a .
  • the guide of the folded strip 23 in contact with the strip 24 and also the flattening of the folds are ensured, in the embodiment shown, by a cylinder 26 which supports it in line with the upper generatrix of the cylinder 25a, by a endless band 27, cooperating with the vertical strand 24a and which is guided by an upper cylinder 28 spaced from the cylinder 25a above to leave a wedge gap 30 between the strands 24b and 27b of the two pressure bands, but positioned in such a way so that its upper surface is lower than the upper surface of the cylinder 25a in order to allow the strip 23 to pass on the way out, by a cylinder 29 which supports the strand 27b against the strand 24b, by a cylinder 30 which elastically supports the strip 27 against the strip 24 in line with the cylinder 25b and a return cylinder 31 (the strip 27 is driven at the same speed as the strip 24 in the direction F ') and finally by an endless strip 32 which is guided on a cylinder 33 to the right of cylinder 2 5b to form a
  • the folding blades comprise a first blade 36 carried by a frame 37 mounted oscillating about an axis 38 and controlled so as to descend to push the strip to be folded 23 towards the endless strip 24 along a line slightly beyond the generator upper of cylinder 25a.
  • the frame 37 also carries a cylinder 39, which can be driven in the direction of the arrow F "', and which, at the end of the descent of the folding blade 36, comes to tighten the part 23' or tail of the strip to bend against the endless belt 27 in line with the cylinder 28. It should be noted that the part 23 ′ or tail of the band is free and only supported in the event of excessive bending by an inclined plate 40.
  • the second folding blade ensuring the portfolio folding has the same elements designated by the same references with the premium but its stroke is horizontal and it brings a transverse line of the already folded strip and the first fold of which descends freely being guided between vertical plates 41, in contact with the strip 24 in the vicinity of the lower generatrix of the cylinder 25b.
  • the cylinder 39 'clamps the upper end of the folded strip engaged between the plates 41 against the strip 32 which rotates in the direction of the arrow F ".
  • the folded strip is therefore forced by driving its two parts located from on either side of the fold initiated by the blade 36 'in the corner space 34. If the tail has a length less than L, its free edge 42 is between the plates 41 but because of the guidance provided by these plates the fold 43 cannot open and its surface is reapplied against the part 23a of the strip to be folded during the engagement between the strip 32 and the cylinder 39 '. If the tail 23' has a length greater than L, it will found folded by the blade 36 'when the fold 43' is formed.
  • the detectors of the position of the rear end 44 of the strip can be of the mechanical, optical or other type.
  • a first detector 45 is placed at a distance 2L from the line of action of the blade 36 and its position is adjustable with precision as a function of the driving speed of the strip to be folded and the delay of the known means, not shown, controlling the oscillation of the frame 37 and the blade 36.
  • the second detector 46 is located at a distance L, measured along the path followed by the strip to be folded 23 along the table and the strip 24 of the line of action of the folding blade 36 '. Its position is also adjustable with precision and it can be corrected according to the results obtained. It is true that the adjustment of the folding format can also be carried out easily by adjusting the positions of the detectors 45 and 46.
  • a tray 47 which can be a transporter receives the folded plans in the portfolio.
  • the feed surface is constituted by a table 100 inclined at 45 ° onto which the strip 23 is brought manually or mechanically.
  • a toothed belt 101 driven in rotation at the same tangential speed as the endless strip 24 drives under the effect of its own weight the strip 23 towards the cylinders 26 and 25a in order to carry out the first folding as mentioned above.
  • the sidewall 103 serves to prevent the strip 23 folded in accordion from opening too much.
