Definitions

  • the present invention relates to a quilting device for leaf-like materials according to the preamble of claim 1 (DE-B-2 507 453).
  • the quilting operation consists of superimposing several folds of leaf-like material of a given length on a support generally consisting of a table.
  • a quilting carriage is used for this purpose.
  • an improved quilting device is used according to the invention.
  • the device comprises a fixed table on which is slidably mounted a carriage carrying a roll of fabric mounted in free rotation on a support and kept in pressure against at least one elastic band without end of drive mounted on two rollers arranged parallel and in a vertical plane, said rollers being driven in rotation by a motor member controlled in position and speed, the fabric being unrolled and descending freely vertically to be lying on the quilting table.
  • the device according to the invention has a contact force, between the fabric and the endless elastic bands for driving the fabric roll, which is precisely adjustable and which is independent of the weight of the fabric roll.
  • the loading of the fabric roll can be fully automated.
  • the tangential drive of the fabric roll allows very precise control of the unwinding.
  • the fabric falls of its own weight, vertically from the lower roller on which the drive belts are mounted and therefore the fabric can be treated directly by the measuring and guiding members.
  • the trolley is provided with means for controlling the edge of the fabric width, which consists of two optoelectronic cells between which the fabric passes and which move on a slide arranged parallel to the fabric. , the displacement of these cells being such that the spacing between them is always centered on a longitudinal axis of the table.
  • the device according to the invention provides perfect centering of the width on a longitudinal axis of the machine and this minimizes the internal stresses of the fabric.
  • the device according to the invention allows very precise dosing of the movements of the carriage and the simultaneous unwinding of the fabric; in particular, it is possible to vary the accelerations and speeds as a function of the different fabrics and thus obtain a perfect deposition.
  • FIG. 1 is an elevational view of an embodiment of the quilting device for leafy materials according to the invention
  • FIG. 2 is a plan view of the means for controlling the edge of the fabric
  • Figures 3 to 3b are diagrams showing the control of the position of the edge of the fabric
  • Figures 4 to 4d are diagrams showing the different operations of quilting performed with the device according to the invention
  • Figures 5 to 5d are diagrams showing the production of a first type of quilting
  • Figures 6 to 6b are diagrams of a second type of padding
  • Figures 7 to 7f are diagrams of a third type of padding
  • Figures 8 to 8d are diagrams of a fourth type of quilting.
  • FIG. 1 there is shown a support member consisting in particular of a fixed table 1, on which is disposed a mattress 2 consisting of several overlapping plies of leaf-like material of a given length, said table 1 being supported by a frame main not shown in the drawing on which is guided in translation via rails a quilting carriage 3.
  • the carriage 3 is driven by a motor 4 controlled in position and speed so as to control very precisely all his movements.
  • the carriage 3 which moves above the fabric mattress 2 is provided at its upper part with a turret 5 which is pivotally mounted on the carriage along a vertical axis by means of a bearing 6. This turret 5 can pivot by report to the carriage 3 around the axis X-X1 centered on the point of fall of the fabric, thus making it possible to create all the types of mattress as will be described later.
  • the turret 5 comprises slides 7 on which are slidably mounted supports 8 in V which receive an axis 9 of a roll of fabric 10, the axis 9 being completely free to rotate on the supports 8 in V.
  • the endless belts 14 are mounted at regular intervals with one another on two rollers 15, 15a arranged in parallel and in a vertical plane, at a fixed position relative to the turret 5. At least one of the rollers 15 is connected by a transmission 16 to a motor 17 fixed on the turret and ensuring the rotation drive of the rollers and the translation of the endless bands 14 which drive the fabric roller 10 when the latter is in contact with said bands under the action of the jack 12.
  • the motor 17 is controlled in position and in speed.
  • a servo means 18 for the edge of the fabric which makes it possible to deposit the width of fabric still centered on a longitudinal axis of the table 1.
  • said means consists ( Figures 1 and 2) of two optoelectronic cells 19, 19a which are fixed on two carriages 20, 20a moving on a slide 21 arranged parallel to the fabric, said carriages carrying nuts 22, 22a which are engaged on a rod 23 threaded on the right and on the left, said rod 23 being rotatably mounted in bearings provided for ends of the slide and driven by a motor 24.
  • the displacement of the cells 19, 19a is such that the spacing between them is always centered on a longitudinal axis of the machine.
  • the cells 19, 19a are arranged in such a way that the tissue 25 passes between them just at the exit of the unwinding system.
  • the cells act via an electronic computer on a motor (not shown) allowing the transverse displacement of the turret 5 via the slides 6.
  • a motor not shown
  • a means for removing the fabric 26 which is vertically movable along the double arrow F and actuated by a motor member controlled in position. This means allows during the vertical descent of the fabric to lie it on the quilting table 1.
  • This means for depositing the fabric 26 comprises a feeler 27 actuated by a jack 28 and which makes it possible to position the means for depositing the fabric 26 at a constant height relative to the upper fold of the mattress 2.
  • the removal means comprises at its upper part an optoelectronic cell 29 making it possible to very precisely stop the end of the tissue 25 at a given height depending on the position of the probe 27.
  • elements 30, 30a for deflecting the path of the fabric 25 and eliminating the folds. These elements are capable of being discarded to allow free passage when the fabric descends between said elements. Two elements 30, 30a are used in order to be able to deposit in both directions.
  • These elements can consist of banana rollers, rollers with jets of compressed air, etc.
  • Each knife is offset from the drop point of the fabric. It is therefore necessary to advance the carriage 3 beyond the end of the mattress by a value equal to the offset so that the knife is above the end of the mattress 2.
  • the slide supporting the knife 31, 31a is capable of moving vertically along arrow F1, so that by lowering the cutting assembly, it comes to bear on the mattress 2 and the knife cuts the fold of fabric flush with the end of the mattress.
  • the quilting device operates as follows: as shown in FIG. 4, the fabric roll, with its central axis 9, (FIG. 1) is placed on the V-shaped supports 8, the jack 12 being in the retracted position.
  • the pressure is reversed in the jack 12 so that the supports 8 slide in the direction of the endless bands 14 to bring the roll of fabric 10 into contact with them.
  • the pressure of the compressed air in the jack is adjusted so as not to obtain a crushing of the fabric or too great an elongation of the endless bands 14.
  • the carriage 3 being immobilized in a place such that the drop point of the fabric is located exactly above the start of the mattress 2 (FIG. 4a), the fabric is slowly unwound and it passes through the cells 19, 19a of servo-control edge until it reaches the optoelectronic cell 29.
  • the elements 30, 30a are in the separated position. We know exactly the distance d between the cell 29 and the upper surface of the mattress which is indicated by the probe 27.
  • the guide elements 30, 30a are then brought together.
  • quilting can be carried out.
  • the carriage 3 moves and simultaneously, in perfect synchronism, the fabric 25 is unwound so as to be deposited on the mattress 2 without constraint (FIG. 4c).
  • the selvage control means ensures the centering of the fabric on the table.
  • the optoelectronic cells 19, 19a are moved apart as much as possible (FIG. 2) and then the tissue is lowered between said cells.
  • the cells 19, 19a are slowly brought together and as soon as one of them meets the tissue, the roll of tissue 10 is moved in the opposite direction (FIGS. 3a, 3b) to return the tissue to the centering position shown in the figure 3.
  • the computer compares the covered surfaces and acts on the tissue so as to balance them.
  • This means allows the width of the width to be measured in real time and this value can be communicated to the central computer and used as a parameter for managing and controlling the operation of the machine.
  • the fabric is rewound up to the level of the cell 29, the carriage 3 is moved above the other end of the mattress 2 and a new fold is deposited.
  • FIG. 5d there is shown a first type of quilting in which the pattern of the fabric is always oriented at the upper part of the mattress, the folds 33 and 33a being arranged as shown in FIG. 5a and the unwinding of the fabric taking place as shown in FIG. 5.
  • a first ply 33 is deposited on the mattress (FIG. 5b) while the return after the ply 33 has been cut is carried out empty (FIG. 5c). Then, the carriage 3 performs a second forward movement during which it deposits a second fold 33a on the fold 33 (FIG. 5d). This displacement after a cut at the end of the mattress is followed by a second vacuum return (FIG. 5c) and so on.
  • the carriage 3 makes a first outward journey during which it deposits a fold 34 on the mattress (FIG. 6a). After a cut at the end of the mattress, the carriage carries out a return journey during which it deposits a second ply 34a on the ply 34 (FIG. 6b). The operation is thus repeated after cutting the folds at each end of the mattress.
  • FIGS. 7 to 7f a third type of quilting is shown in which the carriage makes a first outward movement (FIG. 7a) during which a fold 35 is deposited on the mattress. After cutting at the end of the fabric, the carriage 3 returns empty to its starting point (FIG. 7b) where the turret 5 is rotated by 180 ° (FIG. 7c).
  • the carriage then performs a second forward movement (FIG. 7d) during which it deposits a ply of fabric 36 on the ply 35 and after cutting at the end a second vacuum return (FIG. 7e).
  • FIGs 8 to 8d there is shown a fourth type of padding in which a first ply 36 is deposited on the mattress during a first go ( Figure 8a).
