  • ABSTRACT A machine for the automatic formation of rolls of piece-fabrics having a pre-estab1ished length is pro vided with a winding up device, a plane on which the fabric is fed, a cutting device actuated by sensor means responsive to signals applied to the fabric or to a counting device, gripper means adapted to seize therebetween the fabric after the cutting operation and carry it to the winding up device, a feeder of card board tubes which are the core of the rolls, said feeder comprising means adapted to unwind a sheet of paper from each tube and means for positioning thereafter the tube on the winding up device so that the end of fabric drawn by said gripper means, held between the tube and the unwound sheet of paper, is the origin of a new roll of fabric.
  • An automatiic device for discarding the defective fabric is also provided, when the beginning and the end of each defective length of fabric is indicated by previously applied signals.
  • the above mentioned cutting device carries out two cutting operations and the two fabric edges are then joined together by overlapping and the winding up of the roll continued.
  • a device for counting the length of defective fabric is also preferably provided.
  • Said operation is carried out manually, i.e., a worker, after having established in any known manner that the length is the desired one, causes the machine to stop, cuts the fabric, removes the small roll formed, puts into the machine a new cardboard tube which constitutes the core of the roll whereonto he causes to be wound up another 50 m long piece ready for sale.
  • This sequence of operations obviously involves a considerable waste of time and labour, so that the advantages obtained by effecting the finishing operations on very long pieces of fabrics are considerably reduced.
  • the machine according to this invention essentially comprises a pair of grippers which are adapted to stop the fabric in the points where the piece has to be cut and, subsequently, to feed the fabric again; a cutting device for cutting the fabric in order to separate one piece from the other; a feeder of tubes on which the roll has to be formed; an automatic winding up device; and means for discarding the defective fabric.
  • FIG. 1 shows a schematic perspective view of a first embodiment of the machine according to this invention
  • FIG. 2 shows a second embodiment of the machine according to this invention
  • FIG. 3 shows a detail of FIG. 1 or FIG. 2;
  • FIG. 4 shows a schematic side-view of the machine according to FIG. 1 without the tube feeder and illustrating in particular the automatic winding up group;
  • FIG. 5 shows an end-view taken from the righthand side of FIG. 4
  • FIG. 6 represents a perspective view of the same machine in particular with reference to the automatic discarding device of the defective fabric
  • FIG. 7 represents a schematic side-view of a detail of FIG. 6 during a given operating moment.
  • FIG. 8 represents an enlarged perspective view of a detail of the machine as represented in FIG. 6.
  • the fabric 1 coming from the finishing machine and moving forward from the left-hand to the right-hand side along the direction of the arrow F.
  • the fabric in question consists of a plurality of big pieces joined together to expedite the finishing operation.
  • signaling means 6 which are normally self-sticking phosphorescent pieces of paper existing in trade and capable of exciting a photoelectric cell 7.
  • said signaling means 6 might also be different, such as e.g. magnetized or in general metal signals, i.e., elements which can be sensed by an electric, electronic or pneumatic sensing element 7..
  • the signaling plates 6 or the equivalent elements are placed every 500 m, i.e. at the point where the big pieces are joined together. Consequently, if only this signal should exist, the winding up machine would stop only every 500 m. Since on the contrary a cutting has to be performed every 50 m, another already known measuring apparatus, e.g., a
  • the fabric 1 when advancing from the left-hand side to the right-hand side in the sense of arrow F, the fabric 1 passes through a pair of open grippers 3 and 3, then over a plane 4 provided with two parallel slots 5 and 5' perpendicular to the advancement sense of the fabric, above which the sensing device 7 is arranged.
  • the cutting disks 8 and 8 can run in these slots, as they are caused to rotate by the motor 9 and driven along the width of the fabric on the supports 10 and 10 by a pneumatic or electric driving means, not shown in the figure. This constitutes the fabric cutting device.
  • the feeder of empty cardboard tubes constituting the core of the rolls to be formed includes a magazine of empty tubes 12 with an underlying feeding carriage 13 actuated by a pneumatic piston 14 and provided with a feeding slot 17.
  • a tube 16 coming from the container 12 falls into the slot 17.
  • the piston 14, moving towards the lefthand side brings the carriage to the position represented by a full line in FIG. 1, i.e., with the tube 14 in the position 16' inside the slot situated in 17.
  • a device for picking up the tubes consisting of a pneumatic piston 21 which bears centrally through a support 22 a bar 21a, along which two lever arms 18 and 18' can slide through two supports 22' and 22" under the action of two pistons 19 and 19'.
  • the lower end of each lever arms 18, 18' bears a conical mandrel 20 and 20' respectively.
  • the two pistons 19 and 19' cause the two lever arms 18 and 18' to close, so that the conical mandrels 20 and 20' are introduced into the two ends of the tube, while catching it strongly.
  • the piston 21 will come down, thus bringing the tube 16 into the position 16".
  • the pistons 19 and 19' will cause the two arms 18 and 18' to be removed, thus causing the mandrels to be disengaged from the ends of the tube which will fall into the tray 23 to be then seized again by the conical mandrel 24 of the winding up device. Thereafter, the tray 23 will come down in order not to interfere with the winding operation.
  • the mandrel indeed, not only has a translatory movement in the longitudinal sense of the tube, as indicated by the arrow H, but also has a rotatory movement in the sense of the arrow G imparted eg by a pulley connected to a motor, since besides having to hold the tube, it will also have to effect the winding operation in order to form the desired roll.
  • FIG. 3 better shows the grippers 3 and 3' opened, while the fabric 1 indicated by a dashed line passes between them.
  • the cutting disks 8 and 8' which, keyed on the shaft 27, enter the slots 5 and 5 respectively, and rotating whirlingly cut the fabric.
  • These cutting disks as indicated in FIG. 1, after having entered the working plane 4 to cut the fabric come out completely therefrom and are positioned outside of the path of the fabric.
  • FIG. 4 shows the grippers 3 and 3 closed which have pressed between them the fabric 1 as a result of the action of piston 25 which has pushed downwards the gripper 3.
  • the control impulse to piston 25 is given by the sensing device 7 or by the above-said means for measuring the length of the roll to be formed.
  • the part of plane 4 bearing such slots and which is pivotedly mounted on the fulcrum 26 rotates, under the action of a not represented pneumatic piston, in order not to hamper the following operations, and is positioned as indicated by the dashed line in FIG. 4.
  • the pneumatic piston 30 operates the supporting carriage 28 of the pair of grippers 3 and 3 and by causing it to slide along the guiding rail 29, brings it into the position indicated by 28 drawing with it the grippers 3 and 3' which still press between them the fabric 1.
  • the piece of fabric pressed by the grippers 3 and 3' will have to constitute the beginning of a new roll, the preceding roll being completed and separated by the cutting of the fabric. Once formed, the roll will have to be removed from the winding device, to permit the mandrel 24 to clasp a new tube 16" onto which the piece of fabric carried by the pair of grippers will have to be wound up.
  • the feeding carriage which is driven by the piston 14 conveys the tube 16 into the position 16', then, the conical mandrels 20 and 20 close under the action of the pistons 19 and 19, they clasp the tube and lift it while the carriage 13 returns to its backward position whereafter they lower it to the position 16", asexplained before.
  • a motor 35 through the pulleys 41 and 42, causes the mandrels 20 and 20', and consequently the cardboard tube held by them, to rotate in the opposite sense with respect to the normal winding up sense.
  • a plurality of nozzles 36, 36', 36" etc. direct a blow of compressed air tangentially onto the tube 16". Since on these tubes, already known in trade, there is commonly wound up a certain quantity of paper, the combined action with a contrary effect of the rotation imparted by the motor 35 and the air jets of the nozzles 36, causes the paper to be unwound.
  • the piece of paper which is unwound from the tube 16" falls down until it is sensed by the photoelectric cells 37 and 37' which send to the motor 35 an impulse causing it to stop.
  • a timer 38 which starts to count the time upon the entering into action of the motor 35. If, after a certain pre-established time length, the photoelectric cells 37 and 37 have not sensed the presence of the lower edge of the paper 39, this means that there is some defect which has prevented the paper from being unwound,'so that the timer 38 causes the stopping of the machine on which the intervention of an operator is required, the operator being called, if so devised, by an auxiliary acoustic or luminous alarm signal.
  • This type of safety device is very important in the operation of the machine of this invention.
  • the piston 21 immediately drives again upwards the bar 21a with the supports 22, 22' and 22" and thus also the arms 18 and 18' which are lifted leaving clear room for the following operations.
  • the mandrel 24 actuated by the piston 43 moves from the left-hand to the righthand side and holds the cardboard roll 16" which in the meantime rested free on the tray 23.
  • the tray 23 will preferably have a concave, in particular semicylindrical shape, to avoid that the tube 16" can roll away.
  • the grippers 3 and 3' pushed by the piston 30, had arrived into the position 28' of their supporting carriage, still keeping tightly between them the piece of fabric with which a new roll will have to begin.
  • the lower gripper 3 is provided with a cam in the form of a sloping plane 44 contrasting in the position 28' a fixed projection 45 having an opposite slope which causes the pair of grippers to stop and rotate. In this position, the fabric 1 is in contact with the roll 16" while the paper 39' unwound from the roll passes over the cylinder 47 which is integral with the tray 23.
  • the piston 46 causes the lowering of the edge of the tray situated in front of that on which the cylinder 47 is mounted and, since the tray 23 has its fulcrum in the central point 48, the cylinder 47 is lifted and presses the cardboard roll 16', so that the fabric 1 is compressed between the cardboard roll and the paper 39.
  • the grippers 3 and 3' open themselves and return to their initial position.
  • the motor 49 (FIG. 5) through the pulleys 50 and 51 causes the mandrel 24 to rotate, so that the cardboard tube 16" starts to rotate driving with it the fabric and the piece of paper and starts to form a new roll.
  • the piston 52 causes the lowering of the support 53 of the tray 23 to avoid that the roll which is being formed would collide against the latter owing to its growing diameter.
  • the plane 4 again rotates of upwards and takes again its initial position in front of the grippers 3 and 3 to make possible a further cutting operation of the fabric.
  • FIG. 2 a second embodiment of the machine is represented as in FIG. 1, wherein the grippers 3 for carrying the initial piece of fabric of each new roll are caused to move by a lever 28" instead of the carriage 28 thus simplifying the rotation of the pair of grippers at the end of their travel towards the winding up device.
  • the actual winding up device is slightly modified since 24 does not indicate a mandrel provided also with a translatory movement and adapted to hold the cardboard roll for the winding up operation, but simply is the shaft of a roll X on which there rests frictionally driven, the cardboard tube supported by the mandrel 20.
  • the automatic winding up machine has been represented taking particularly into account the device for discarding automatically the pieces of defective fabric.
  • signals indicating the beginning and the end of each defective piece.
  • Said sig nals can be sensed by appropriate sensing elements and are e.g., either phosphorescent papers capable of exciting a photoelectric cell situated in a fixed position or magnetic, metallic, etc., elements, which can be detected by any known means, so that, when the defective fabric arrives on or a little before the slot 5 of the advancement plane along which the fabric is cut, the signal detecting element (not shown in the figure) sends an impulse to the fabric feedirig device, causing it to stop and blocking the fabric 1 in this position for the cutting operation.
  • the blade 8 of the cutting device rolling over the slot 5 cuts the fabric, of which the portion pertaining to the piece being wound up falls down by gravity onto a roll 64 parallel to the cylinders X and 47 of the winding up device and situated in an intermediate position between these and the cutting device.
  • a series of suction members 62 connected through a flexible pipe 61 to a vacuum source 60. Said members 62 can slide over the fabric 1 through pairs of small rollers 67, under the action of a double-effect cylinder 63. Moreover, there is provided a pair of rollers 54 positioned transversely and on opposite parts with respect to the fabric so as to press it while effecting, if operated, a conveying action on thefabric.
  • a specific friction device blocks the winding up device, causing the stopping of the shaft 24 of the roll X, and consequently of the fabric already wound up on the tube 16, the cut-off portion of which, retained by the roll 64, falls vertically along a certain length.
  • the rollers 54 are operated and cause the defective fabric comprised between them to move forward, feeding it to the underlying container 68 (from the lefthand to the right-hand side in the drawing).
  • means suited to push the fabric downwards, into the container 68 can consist e.g., of jets of compressed air emitted by a number of nozzles 56 arranged along a conveying pipe 55, but could be made in any other known manner.
  • the end of defective piece will be detected by the presence of a signal of the fabric passing in front of an element which is sensing to said signal. A new impulse will therefore be given for stopping the fabric 1 and for operating the cutting device.
  • the cylinder 63 will actuate the advancing of the suction members 62, which, once they are in the position 5, will cause the fabric 1 to move forward, drawing it with them owing to the suction force applied.
  • the suction members 62 after having overcome the zone corresponding to the container 68, will bring the fabric into the position indicated in FIG. 7, i.e. with the end Y beyond the roll 64 on which the pairs of small rollers 67 are resting at the end of the travel of the series of suction numbers 62.
  • the suction in the members 62 stops, since they are disconnected from vacuum source 60.
  • connection may e.g., be assured by a normally closed valve having a push-button 65 for controlling the opening thereof, as indicated in FIG. 2, is operated only over a certain portion of the advancement travel of the suction group, e.g., by a contrast element 66 having a pre-established length.
  • the two ends of fabric are kept together by the reciprocal friction action effected during the winding up of the total length of the overlapping portion, corresponding to the distance between the roll 64 and the point Y to which it is to be added the length of the extreme piece which hangs vertically by gravity into the container 68. It should be noticed moreoever that the position Y wherein the front end of the fabric is left, drawn by the suction members 62, is rather close to the roll already wound up onto the cylinder 16, so that the winding up tension on the piece is soon added to the above said friction strength between the two layers of fabric.
  • the piston 63 controls the return of the members 62 (without suction) in the starting position represented in FIG. 6.
  • An appropriate measuring device e.g., a counting device C driven by advancement of fabric 1 and rendered operative upon sensing of the signal detecting element, had meanwhile measured the length of the discarded piece of defective fabric, which measurement is in any known manner memorized and will be taken into account by counting device C for recording the length of the fabric and for determining the cutting of the piece at each preestablished length.
  • auxiliary devices may be changed.
  • a different method may be used to bring the piece of fabric next to the winding roll without the rotation of the pressing grippers but for example by lowering first the pressure which is integral with the supporting tray of the roll and lifting it thereafter as said precedingly.
  • the controlling cylinders may not only pneumatic, but also hydraulic or oleodynamic or, if so desired, replaced by electromagnetic controlling devices. There will be provided moreover all connections, relays, limit switches, electrovalves for controlling the cylinder position systems, timers, etc., required to ensure coordination and synchronization of the various operating stages.
