Definitions

  • the present invention relates to the folding of a flexible rectangular piece, in particular textile, and more particularly the formation of successive folds in the same direction, parallel to one of the edges of the piece.
  • the packaging of large rectangular pieces, such as sheets, blankets, requires folding the piece before being placed in its final packaging.
  • the folding operation is well known in the making, and various methods and devices have been developed for folding pieces, in particular rectangular pieces.
  • a process is known for the formation of two successive folds in a direction parallel to one of the edges of the part. This process consists in placing the part to be bent on a flat surface above a slot positioned so that the bending axis of the part is in line with the slot, in making the part penetrate between two first sheets under the action of a rigid plate, then the plate being raised to penetrate the folded part into a second slot between two second sheets perpendicular to the first.
  • the part is first folded in half then, in double thickness, it is again folded in two in the same direction parallel to one of the edges of the part.
  • the above method has significant drawbacks. It is limited to a succession of two folds, and above all it requires for its implementation a very bulky installation comprising a feed table on which must be placed flat the part to be folded.
  • Also known from American patent US-A-3,190,512 is an apparatus for forming folds on a textile sheet material.
  • the apparatus includes folding stations each having a plurality of channels and a plurality of movable members cooperating with each other so that the movable members move vertically within the channels correspondents according to an adapted sequencing.
  • the apparatus described in this patent is used for pleating drapery articles and the folds formed are then stapled to keep the folds in shape.
  • the above installation has the advantage of being able to operate in hidden time.
  • the first quadrant is intended for the blocking operation of the front edge of the part on the external face of the first housing, this face being horizontal.
  • the second quadrant is intended for the operation of penetration of the part into the various housings, it is the actual folding.
  • the third quadrant is intended for entering and extracting the part.
  • the installation according to the invention is advantageously automatic and includes rotation means, controlling the rotation of a quarter turn of the frame supporting the 4 sets of n housings, as soon as the longest operation, either blocking or folding , or extraction is complete.
  • the folding installation illustrated in FIG. 4 is an automatic folding installation according to the invention operating in masked time.
  • the central frame 13 is mounted, movable in rotation, around the horizontal axis 14.
  • This frame 13 has a substantially square cross section.
  • Each of the faces of the frame, delimiting a quadrant, supports a set of 3 boxes (1a, 1b and 1c).
  • In the second quadrant (B in Figure 4) is placed a set of three movable blades (3a, 3b and 3c) opposite the boxes (1a, 1b, 1c) fixed on the frame.
  • In the third quadrant (C in Figure 4) is placed a set of four movable clamps (11a to 11d), opposite the recesses made in the walls of the boxes.
  • Figure 1 shows the part of the installation corresponding to the second quadrant B.
  • the three boxes 1a, 1b and 1c are attached to each other and have a U-shaped cross section, the boxes being open on the upper face and a side face (not shown in figure 1).
  • the boxes are joined, the box 1b having a common wall with the box 1a on the one hand and the box 1c on the other hand. All the walls have along the short side 2 ′ the same recess 2.
  • the blades are connected by rods 4a, 4b and 4c to their own translation means, not shown, for example double-acting hydraulic cylinders connected by fluid connections to a unit controlling the distribution of fluid according to a program corresponding to the operations described below. .
  • the translation of a blade the data is such that in the rest position (as shown in Figure 1) - for example the corresponding cylinder being retracted rod - it is external to the box 1a, and that in the folding position - by example the corresponding jack being rod extended - it is penetrated into the box and near the bottom 5a thereof, without however touching either the walls or the bottom of the box 1a.
  • the cylinder stroke is adjustable to vary the penetration depth, depending on the desired folding width.
  • the shoe 6 is the entire length of the box 1a. It is connected by the rod 7 to its own translation means, not shown, for example a double-acting hydraulic cylinder.
  • the translation of the pad 6 is such that in the locking position (as shown in FIG. 1) - rod of the jack extended - it is applied over the entire length of the external face of the box 1a, and that rest position - cylinder rod retracted - it is far from the box.
  • the axis of rotation 14 is connected to a motor and to a control system, controlling the rotation of the axis a quarter of a turn at a time, with an intermediate delay.
  • the duration of this time delay is at least equal to the duration of the longest operation, as defined according to the operating conditions specific to the part to be bent and to the industrial environment.
  • the operation of the installation is as follows.
  • the operator places the front edge of the part 8 on the plate 15 formed by the upper face of the first wall of the box 1a located in quadrant A. He introduces the front edge under the pad 6, so that the front edge of the part is parallel to the axis of rotation 14.
  • the jack controlling the pad 6 is actuated, the pad 6 is applied to the piece which is then blocked by its front edge. The piece hangs along the caissons.
  • the first blade 3a descends into the box 1a and forms the first fold, then successively the blades 3b and 3c.
  • the blade 3a drives the part to enter the box 1a to the bottom 5a of said box. This penetration causes the displacement of the rest of the part 8 resting on the other boxes in the direction of the arrow D.
  • the other blades 2b then 2c are then actuated successively (FIGS. 2c and 2d).
  • Piece 8 follows a baffled path between the walls of the boxes and the blades, thus forming the sought-after accordion folds.
  • the part 8 being fully folded, all the blades 3 are actuated in the rest position (FIG. 2e).
  • the depth of the boxes and the number of these are chosen according to the total length of the piece 8 to be folded, so that all the blades having penetrated all the boxes the piece is entirely inside the boxes or possibly the rear edge of the part is in contact with the outside face of the last box 1c.
  • the plate 15 is again cleared and the operator can place the next part, then control a rotation of a quarter turn of the axis of rotation 14, which drives the part of quadrant B in quadrant C.
  • each clamp 11 Opposite the recesses 2 formed in the four walls of the three boxes are positioned four clamps 11 connected by rods 12 to their own translation means, not shown, for example double-acting hydraulic cylinders.
  • the translation of a given clamp 11 is such that in the rest position (as shown in FIG. 3a) - rod of the jack retracted - it is outside the casing 1a, and that in the gripping position - rod of the jack extended - it is in the recess 2a.
  • Each clamp of a known type, comprises for example two jaws, at least one of which is movable relative to the other and means for moving these jaws, between a first position where the jaws are open and a second position where they are closed and capable of gripping room 8.
  • the set of four clamps 11a to 11d is actuated so that the latter, jaws open, advance and penetrate at the level of the recesses 2 formed in the walls of the boxes.
  • the closing of the jaws being controlled the part is gripped by the four pliers simultaneously then the four pliers, jaws closed, are moved into the extraction position as indicated in FIGS. 3c and 3d in the direction of arrow D and the part folded in successive folds is deposited on the support 12 after opening the jaws and removing the clamps 11.
  • the depth and the number of boxes depend on the size of the part to be folded, as well as the number of folds desired.
  • the distance between two blades which is equal to the width of a box depends on the structure of the constituent material of the part and in particular of its thickness. Thus this distance may be small, of the order of 20 millimeters, for a sheet, but it will be greater, of the order of 30 millimeters for a blanket.
  • the part leaving the installation described above and deposited on the support 12 comprises a succession of folds, in accordion, parallel to the front and rear edges of the part.
  • This piece, thus folded, can be transported, manually or better automatically, to another installation or another device of the same type in order to be folded in accordion in successive folds but in the direction of the other edges of the piece.
  • the penetration means can take various forms other than blades, for example rods sliding at each end in rails fixed along the caissons, or pneumatic means pushing the part back into the caisson by action of an air jet.
  • the extraction of the part which has been described above by the small side 2 ′ of the boxes can also be carried out by the face opposite the bottom 5 of the box.
  • the recesses are made on the corresponding side of the walls, and the extraction means are placed opposite said recesses.
