Definitions

  • the present invention relates to a machine for folding and stacking laundry items, in particular sheets, mounted following a calender of an installation for drying and ironing such laundry items.
  • Such machines are already known which make it possible to carry out several successive folds of the same piece of linen in the longitudinal direction and possibly a final folding in the transverse direction.
  • Such machines are described for example in patents DE-A-2 815 599, BE-A-568 116, FR-A-2 413 495 and US-A-3 702 696.
  • These known machines generally include a conveyor belt endless parallel on which the pieces of linen to be folded are placed and which pass these linen through one or more stations of longitudinal folding. After having been folded one or more times on itself, each piece of laundry can arrive at a transverse folding station, as described in US Pat. No. 3,702,696.
  • the piece of laundry In this station the piece of laundry, already folded twice on itself in the longitudinal direction, extends transversely between two parallel conveyors and is then taken from below, substantially in its middle part, by a longitudinal transport rod which is raised and which carries the piece of laundry upwards, forming a vertical fold open downwards, then towards a lateral platform, in order to form a stack of folded laundry items on this platform, after which the stack of folded laundry items is discharged by an auxiliary transporter.
  • a transverse folding station has the disadvantage that each piece of laundry is simply lifted in the middle, by the transport rod, and therefore the piece of laundry hangs freely on either side of this rod.
  • the transport rod is animated by a cyclic movement constituted by two rotations around an axis, in opposite directions, with two intermediate phases of translations, in the opposite direction parallel to this axis and therefore such a mechanism does not lend itself to obtaining a high folding rate.
  • the machine is fully automated, in no way requiring the intervention of personnel because it is controlled by detectors, preferably pneumatic, which signal the arrival and passage, in front of each member of the machine, of a part of linen to be folded and control the start-up for the necessary time, the stopping and waiting for the arrival of the next piece of linen, for all the moving parts of the machine.
  • detectors preferably pneumatic, which signal the arrival and passage, in front of each member of the machine, of a part of linen to be folded and control the start-up for the necessary time, the stopping and waiting for the arrival of the next piece of linen, for all the moving parts of the machine.
  • the conveyor is provided, in the longitudinal direction relative to the outlet of the grille 2, with a return pulley 4 at each of its ends, the upstream pulley 4 being mounted below the spout 2 of the radiator grille, in order to receive the length of the piece of laundry 5 leaving the spout of the drying and ironing installation (FIG. 1).
  • the device then comprises, along the conveyor belt A and in the direction of longitudinal movement of its belt according to arrow F1, an air jet detector 6 of the arrival of the laundry 5, then a first station 7 for folding the linen in the longitudinal direction which is described in more detail below.
  • the device After this first longitudinal folding station 7 and still in the direction of longitudinal movement of the belt conveyor A, the device comprises a roller 8 for flattening the fold produced by this first longitudinal folding station 7, associated, below the band of the conveyor A, with a counter-support roller 9. These two rollers roll in opposite directions, practically bearing on the opposite faces of the strip.
  • the first longitudinal folding station 7 and the second longitudinal folding station 12 are formed in the same way. We will therefore describe, therefore, only one of these longitudinal folding stations.
  • a folding station firstly comprises a fixed casing 15, placed above the conveyor belt A, at a certain height in order to allow the folding of the linen and its transport by the conveyor belt.
  • This housing 15 carries, at its lower part and upstream relative to the direction of movement of the conveyor belt, a fixed jaw 16.
  • the housing 15 also carries at its lower part a rake 17 in the form of the rectangular grid, articulated, at its upper end, on the downstream part of the housing 15, using a hinge 18 of horizontal and transverse axis.
  • the rake 17 carries, at its lower end, a movable jaw 19 in the form of a roller, which can rotate about a transverse axis supported by the rake 17, located at its upstream end relative to the direction of movement of the strip of the carrier indicated by arrow F1.
  • the two fixed 16 and movable jaws 19 have a length equal to the width of the conveyor belt A.
  • the rake 17 can rotate around the hinge 18, as shown in the drawing by the arrow F2, or in the opposite direction to this arrow, under the action of a lever 20 (FIG. 6) actuated by a jack 21. Under the action of the jack 21, the rake 17 can come to occupy one of three different angular positions , namely an extreme lowered position, as shown in FIG. 1 of the drawing, an extreme high position, as shown in FIG. 2 of the drawing and a waiting position, intermediate between the two preceding ones, as shown in the Figure 3 of the drawing.
  • the folding station 7 or 12 also comprises two fingers 22 placed below the conveyor belt A, on either side of this band, which can tilt according to the arrow F3, around a horizontal and transverse axis 23, also under the control of a cylinder, not shown in the drawing in order to simplify it.
  • the fingers 22, under the action of their jacks, can be retracted below the conveyor belt, or protrude with their downstream end portions above the belt to lift the laundry circulating on the belt, as shown on Figure 1.
  • the housing 15 contains the cylinder 21, as well as a device 26 for adjusting the angular stroke of the rake 17.
  • This adjustment device 26 comprises a threaded bar 27, four nuts 28, a control bar for the cylinder 29 and two springs of tension 30.
  • Such an adjustment device makes it possible to adjust both the low position of the rake 17 as its high position or the intermediate position, as well as the amplitude of rotation of the rake 17 around its hinge 18.
  • the transverse folding station 14 is placed, with respect to the belt conveyors ABCD, with its longitudinal square axis, as shown in FIGS. 4 and 5.
  • This transverse folding station 14 comprises an upper clamp 31 opening, under the control of a jack not shown, in a vertical plane transverse to the longitudinal direction of the ABCD conveyors.
  • This clamp 31 is placed above the conveyor belts and its jaws 32, extending downward, terminate, at their lower end portions, by jaws 33.
  • the station 14 also comprises a lower harrow 34 constituted by a number of vertical plates 35 which are located on each lateral side of each of the conveyor belts, each plate 35 being situated in a plane parallel to the longitudinal direction of the ABCD conveyors.
  • a lower harrow 34 constituted by a number of vertical plates 35 which are located on each lateral side of each of the conveyor belts, each plate 35 being situated in a plane parallel to the longitudinal direction of the ABCD conveyors.
  • there are four plates 35 the plate between the two central carriers B and C missing.
  • These plates 35 are joined rigidly, at their lower parts, by a base plate 36 extending transversely under the four carriers ABCD.
  • the vertical plate 35 which should be in the middle of the harrow 34 is replaced by a guillotine 37 constituted by a vertical plate independent of the harrow 34 and extending between the two central conveyors B and C.
  • the guillotine 37 can in turn also move in a vertical plane parallel to that of the plates 35 of the harrow 34, between a low position (as shown in FIG. 4), with its upper edge 37a in the same plane as the upper edges 35a of the plates 35, and a high position (FIG. 5) in which its upper edge 37a is at the level of the jaws 33 of the clamp 31.
  • the station thus described also comprises means 40 for adjusting the rise of the harrow 34; these means comprising threaded rods screwed into nuts and springs associated with support plates for jacks 38.
  • the operation of the machine according to the invention is as follows: When a piece of linen 3 to be folded arrives through the spout 2 of the radiator grille, it spreads over the strips of the ABCD conveyors traveling in synchronism to pass it through the folding machine 1. By this movement, the piece of laundry 3 reaches, by its downstream front edge, in the direction of movement on the conveyor belts, the air jet of the air jet detector 6 which it cuts, which causes the first folding station 7, simultaneously for the four belt conveyors ABCD. As soon as the downstream edge of the outgoing piece of laundry 5 reaches the fingers 22, these tilt upwards and orient the edge of the piece of laundry 5 towards and on the rake 17, which is in its low position, the movable jaw 19 rolling on the strip of each transporter ( Figure 1).
  • the first fold is thus formed and the piece of linen takes the form indicated at 11.
  • the rake 17 then comes to occupy the intermediate waiting position (FIG. 3), in order to allow free passage to the linen 11 once folded by the continuation of the operations.
  • the rake 17 remains in this position while waiting for a next piece of linen 5 to arrive and again cuts off the air jet from the detector 6 so that, under its control, it descends again with its movable jaw 19 in contact from the conveyor belt to pick up the new piece of laundry that arrives.
  • the piece of linen 11 folded once on itself is brought, by the strips of the ABCD conveyors, under the roller 8, so that the fold formed is well flattened and it continues to be moved towards the station 12 for forming the second fold .
  • This station being shaped in the same way as the station 7 for forming the first fold, the operations are repeated as already described.
  • the piece of laundry 13 comes out folded twice on itself, therefore in four, as shown in Figures 1,2 and 3, both times in the longitudinal direction of its movement by the strips of ABCD conveyors.
  • the piece of laundry 13 thus folded continues to move to reach the transverse folding station 14 ( Figures 4 and 5).
  • the piece of laundry 13 is, with respect to this transverse folding station, flat, as shown in FIG. 4 of the drawing, and it cuts off the air jet from the air jet detector 39, which controls the putting this station into operation 14.
