Definitions

  • the invention relates to an automatic machine for cutting, folding and packaging sheets of flexible materials, cut into wound strips.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims, solves the problem of producing strips of flexible material, cut, folded, cut and packaged continuously on a machine comprising means for positive drive of the strips, means for air guidance of the bands towards cutting members acting periodically between two of the means for bending the thickness of the bands, and arrangements for guiding and transferring the folded and cut bands towards storage, stacking and / or d 'bagging; all these workstations being controlled automatically and adjustable, by a motor driving variable speed drives, transmission means and means for driving and guiding the bands.
  • the general speed of the machine is given by a motor 1 articulated in 2 to one of the uprights 3 or frame, and carried by a pivoting plate 4.
  • the speed of the motor which is transmitted to the organs of the machine is variable by system screw-nut 5 connected to a handwheel 6, to act on a variator composed of a pulley with variable diameters 7, wedged at the end of the motor output shaft 1 and connected by toothed belt 8, to a pulley 9 of larger diameter, wedged on a shaft 10 integral with the upper part of the upright 3.
  • the pinion 11 meshes with a pinion 13 of larger diameter, wedged on a shaft 14 integral with the upright 3 on which is also wedged a pulley 15 which is one of the elements of a movement transmission assembly constituted by a toothed belt 33, wound on pulleys 16, 17, 18, 19, wedged on shafts 20, 21, 22, 23, crossing the two uprights 3, 3a.
  • This assembly being in adjustable tension by a tensioner pulley 24.
  • the pulley 12 wedged on the shaft 10 is connected by toothed belt 25, to a pulley of smaller diameter 26, wedged on the input shaft of a second variable speed drive 27, with adjustment 28, which is integral with the upright 3 and the output shaft of which carries a pulley of small diameter 29, connected by a toothed belt 30 to a pulley of large diameter 31, wedged on a shaft 32 passing through the uprights 3, 3a. All of these elements emerge clearly from FIGS. 5, 6 and 7 of the drawings.
  • the shaft 32 receives at its other end external to the upright 3a, a pulley 34 responsible for transmitting by toothed belt 35, the movement given by the shaft 32, with three pulleys 36, 37, 38, rotating on axes 39.40 , 41, fixed at the amount 3a.
  • the three aforementioned pulleys have on their internal face, hollow profiles forming a cam, to cooperate with rollers 42 or similar means, carried by levers 43 and rods 44, connected to the shafts 39, 40, 41, as can be seen. better in FIGS. 2, 3 and 4.
  • the position of the rollers 42 in the cams can be adjusted by vernier 45 to precisely adjust the control as a function of the desired folds in the strip of material, which are carried out under the conditions set out below. afterwards, by sheets or benders proper 46, 47, 48, carried at the end of the rods 44.
  • the toothed belt 35 is also wound on a tensioner pulley 49 then on a pulley 50 oriented relative to the upright 3a and the internal face of which has a boss 50a suitably profiled to pass under each lever 51 articulated at 52 to the upright 3a and the other end of which, in the form of a fork 51a, is inserted between two elements of a cone clutch 53, as shown in FIGS. 8 and 10.
  • a pinion 53a of the clutch can mesh with another pinion 54 carried at one end of a shaft 55 integral with the upright 3a and whose other end inside the two uprights, receives another similar sprocket 56 which can in turn drive two pinions in direct drive 57, 58, wedged at the end of two cylinders 59, 60 carried by flanges 61 integral with the uprights.
  • the cylinders 59, 60 receive over their entire length, flexible cutting blades 62 which are engaged in helical slots 59a, 60a of the cylinders, and held firmly at the bottom of their slot, by helical wedges of the same pitch, 63, placed in pressure against the blades, by multiple corners 64 housed in recesses 59b, 60b of the cylinders and fixed by screws 65, as can be seen in FIG. 12. Note that the screws 65 pass through nuts 66 made integral with the corners 64, to ensure the ascent of said corners, upon disassembly.
  • One of the two cutting cylinders has internally a prestressed torsion bar, the adjustment housing 67 of which can be seen in FIG. 11, intended to keep the blade of said cylinder in pressure against the other blade, throughout the duration of the cut. .
  • the torsion shaft In the standby or rest position of the cylinders (when the clutch 53 does not act), the torsion shaft is wedged back on an internal stop.
  • the other cutting cylinder has at one end a roller 68 in contact with a cam 69 of the first cylinder, at the start of the contact of the two blades (as illustrated in FIG. 11). Then, when the two blades are in continuous contact during the entire cut, the roller 68 escapes from the cam.
  • the clutch 53 is connected to the shaft 20 driven by the pulley 16.
  • This shaft 20 also carries between the uprights 3, 3a, a cylinder 70 with multiple grooves 70a, in which are engaged curved pallets 71 integral with a bar 72 pivotally mounted on the uprights ( Figures 13, 14) and whose utility will become apparent from the following description.
  • the cylinder 70 is part of a set of means for continuously driving the strips of material to be folded and cut, the path of which will now be described with particular reference to FIGS. 1 to 6.
  • the strips M of materials are generally folded longitudinally before winding on a reel B. Otherwise, the longitudinal folds can be carried out in a conventional manner, by folding arms, between the reel B and entry into the machine.
  • the folded strip is positively driven by take-up rollers 73-74 aligned vertically, then by take-up rollers 75-76 aligned horizontally.
  • the roller 75 is formed on the shaft 23 carrying at the end the pulley 19 forming part of the transmission assembly mentioned above. Therefore, it is motor and transmits its movement to the roller 76 on the one hand, and to the rollers 73-74 on the other hand, by pinions 77, 78, 79, 80, 81, as illustrated in FIGS. 5 and 6 .
  • take-up rollers 74, 76 are applied under pressure against the rollers 73, 75, by any means such as eccentric levers, symbolized in the drawings by arrows (FIG. 1).
  • the strip thus called descends vertically between the walls of a chamber 82 tightly contiguous under the rollers 75-76, in order to avoid the winding of the strip on the take-up rollers, and connected to a circuit more particularly illustrated in FIG. 15 where we see a suction turbine 83 with electric motor 84, which sends air in a box 85 communicating with a humidifier 86.
  • the humidified air is directed by one or two pipes 87, in the chamber 82, in order to correctly guide the strip M by effect of blower and also of suction by the manifold 88 positioned below and connected to the turbine 83 by a pipe 89.
  • a hygrostat 90 inserted in the suction manifold, controls the percentage of humidity to be obtained.
  • the strip M then engages between the cutting cylinders 59, 60 in the standby position, then is directed by appropriate lanes, against the cylinder 70 whose pallets 71 are retracted into the grooves 70a, as illustrated in broken lines at Figure 13.
  • smooth rollers 91, 92 and a third smooth roller 93 is also applied under pressure against the roller 92. These rollers are called subsequently, respectively: rolls of the first ply, the second fold and the third fold.
  • the folded bands pass between two pressure or ironing rollers 96, 97) one of which, the roller 96 for example, is driven by its mounting on the shaft 22 connected by the pulley 18 to the transmission belt 33, and the other, the roller 97, is in adjustable pressure against the first, by a lever and eccentric device for example, as for the take-up rollers.
  • the strip arriving against the cylinder 70 is applied between this cylinder and the roller of the first ply 91, by the sheet metal or bender 46 controlled from the cam pulley 36, by the assembly 42, 43, 44.
  • the blade cylinders 59, 60 actuated by the clutch 53, cut the strip to the desired length.
  • the second folder 47 pushes the strip between the cylinder 70 and the roll 92, in order to make the second fold (FIG. 3).
  • the next strip which is in the process of forming the first fold is separated from the previous by protruding from the pallets 71 controlled from their pivoting bar 72, by rods and levers 98, 99, articulated on the roller 92 of the second fold ( figure 13).
  • a receiving plate 100 is provided, placed above the rollers 92, 93 and quickly retractable by any means associated with the third folder when it acts on the strip (Figure 3).
  • the folded belts can be treated in different ways.
  • FIGS. 16 and 17 There is illustrated in FIGS. 16 and 17, an automatic strip stacking device, intended to easily sort a determined number of strips, for their packaging.
  • the folded bands released from the ironing rollers 96, 97, are pressed onto the conveyor belts by a retaining plate 101 articulated on rods 102 mounted for rotation and controlled sliding on the pivot axis 103 of a first comb 104 which, in the rest position, extends substantially in the direction of travel of the belts up to the proximity of the roller 96.
  • the comb 104 is controlled by any suitable means, to pivot on its axis, in the direction of a magazine 105, by driving the folded strip between it and the retaining ring 101, as can be seen in broken lines in FIG. 16.
  • a second offset comb 106 articulated by lever and cam 107 to a shaft 108 controlled in any known manner, passes through the crenellated ends 105a of the magazine, to separate the stack of strips formed in a corridor, from the strip which will be deposited.
  • the second comb 106 pulled by its link 107, retracts then rises behind the first comb by hooking the rods 102 of the retaining plate 101 which in turn pivots and thus frees the folded strip (Figure 17).
  • the first comb 104 then returns to the position for taking up the strip, while the second comb 106 is replaced in the entrance to the magazine.
  • a cam and electromagnet device (not shown), associated with a preselection counter, acts on the first comb 104 when it is in the strip gripping position, to move it slightly upwards (arrow F1, figure 17), so that it takes the folded strip earlier. As a result, the strip will be dropped in the magazine offset upwards, which easily delimits a stack of strips of the next, for packaging.
  • the folded and cut strips are bagged directly in an automatic manner.
  • end roller 95 there is at the end of the end roller 95, conveyor belts 94, take-up rollers 109, 110 for upper and lower strips of paper P1, P2, wound in reels 81, B2.
  • the lower take-up roller 109 is driven in rotation by a gear train (arrow F2, FIG. 18), from a differential shown diagrammatically at 111 and connected on one side with the shaft 21 of the third ply, by means of pulleys 112, 113, toothed belt 114 and tensioner pulley 115, while the upper roller 110 is preferably articulated under pressure on the other.
  • the lower rollers 117 are driven in rotation from the differential 111, by means of a gear train (shown diagrammatically by the arrow F3, FIG. 18), while the upper rollers 116 are driven from the lower rollers, by pinions .
  • the paper strips are then engaged between two knurls 118, 119 meshing together, each consisting of a cylinder preferably equipped with three active helical and equidistant parts, 118a, 119a, intended to weld transversely along two close lines b, the strips of paper, between the folded strips M, so as to close the front and back, the bags S.
  • the upper wheel 118 is connected to a step-by-step control 120, with braking similar to that of the clutch (by rollers and notches), by means of a bevel gear 121; said control 120 being itself connected to the differential 111 and to the shaft 32 for controlling the folding cams driven by the variator 27, this by means of pulleys 122, 123, a toothed belt 124 and a pulley tensioner 125.
  • the paper strips are called up positively by two other call rollers 126, 127, pressurized against each other and whose upper roller 126 is rotated from the roll 110, by chain transmission 128 or similar.
  • the strips of paper closed on four sides are cut between two lines b, by two cylinders 129, 130 one of which, the upper cylinder 129, is equipped with three equidistant cutting blades 129a, arranged in a helix, and it is connected to the differential and to the control step by step, by a second bevel gear 131 at the end of the same connecting shaft 132.
  • the lower cylinder 130 is smooth and not controlled.
  • transverse welding knobs 118, 119 and the cylinders 129, 130 are mounted adjustable longitudinally by bearings 133 sliding on parallel uprights (not shown), to adjust the welding and the cut to the lengths of sachets chosen.
  • these four elements are inclined transversely with respect to the movement of the paper strips, at the same angle as the pitch of the propeller, in order to make a cross-border moletago ot a section perpendicular to the direction of df ⁇ t)! C ment .
  • a speed is obtained at the output of the differential as many times lower as there are folds to be produced in the strips M, that the spacing between two folded strips to be bagged is introduced by the ratio given to the camshaft 32 for controlling the folding cams, and that the linear speed of the transverse welding knobs and of the cutting cylinders is equal to the speed of movement of the paper strips.
  • the strip M can be folded in any number of times, in thickness; it is enough to arrange the organs accordingly.
