Definitions

  • the invention relates to a machine for treating and preparing bands, and in particular bandages, after their manufacture.
  • the object of the invention relates in particular to the technical sectors of the handling of strip materials and the treatment of textiles after manufacture.
  • the machine according to the invention is essentially composed of a succession of stations according to which, the strips stored on the mat, are unwound at constant voltage by electromagnetic couplers associated with the drive motors and with continuous latching strips of different materials, then brought either to a means of shrinking by vaporization under reduced tension, by means of at least one donor or store device; either directly to a drying and shrinking enclosure, then the dried strips pass through a variable reserve of strips by alternating windings, before being wound up in determined lengths with permanent quality control, permanent control and adjustment of the lengths, and means of 'winding of the strips and ejection of the coils formed; all these stations working in synchronism under the control of a control means of the programmable automaton type.
  • the machine comprises in the nonlimiting example illustrated, two supply stations (Al - A2), a retraction station (B), a drying station (C) and a winding station (D) separated from the station (C) by a variable tape reserve device (E).
  • Two feeding stations (Al - A2) are provided for simultaneously delivering two adjoining strips (bl - b2) to the retraction station.
  • the mats (1 S 2) mounted on the station (Al) are transversely offset with respect to the mats (3 - 4) mounted on the station (A2).
  • Each station consists of a mechanically welded frame comprising a rear support structure (5 - 6) for mounting the mat and a front support structure (7 - 8) for the donor or store device (F - G). These two structures can be integral or independent.
  • Each mat is carried in free rotation by a support pin (9) connected to a braking device of the electromagnetic powder coupler type (10) to ensure a constant tension unwinding between the mat and its drive motor (11) shown schematically at the end of the support axis in Figure 2.
  • the bands (bl - b2) wound on the mat (2 and 4) are developed successively on internal alignment rollers (12) and on upper alignment rollers (13) carried in free rotation by mechanically welded brackets (14 -15) which are connected to the supporting structures (7 - 8). Then said bands pass through the donor device which essentially comprises a carriage (16) constituted by two triangular flanges (16a), connected axially to each other by a drum (16b) mounted for free rotation on the flanges, by bearings (16c) or similar organs.
  • the flanges carry free rotation by bearings (16d) or the equivalent, pinions (16th).
  • the flanges (16a) are oriented so that for each flange two pinions mesh simultaneously with racks (17) carried by the rear uprights (7a or 8a) of the front structure (7 or 8), while the third pinions mesh with opposite racks (18) carried by front uprights (7b or 8b).
  • the latter are mounted on the uprights by means of angle profiles (19) adjustable relative to these uprights.
  • the strips (bl - b2) coming from the upper roller (s) (13) are wound on the drum (16b) of the carriage, after having passed through a deflection roller (20): After their winding on the drum (16b), the bands (bl - b2) go up to be wound on another deflection roller (21) and are directed towards the retraction station.
  • the rollers (20 - 21) are respectively rotated freely at the top of the front and rear uprights (7a - 7b) or (8a - 8b).
  • the bands (bl - b2) then pass into the retraction station which aims to make them extensible or to increase their elastic capacity.
  • the bands pass between a drive roller (22) and a pressure roller (23) carried by arms (24) articulated at (25) on the uprights of the frame (26), with springs (27) of elastic return .
  • the roller (22) is connected to a variable speed motor-reducer assembly (28) for driving the bands which then pass horizontally through an insulating enclosure (29) equipped with nozzles (30) distributing water vapor without significant pressure (figure 4).
  • the enclosure (29) is formed of a cover (29a) in double slope and of a base (29b) of general U-shape.
  • the two parts of the enclosure between which the strips pass are constituted by an envelope enclosing an insulating material (31), and troughs (29c) collect the drops of condensation (Figure 5) outside the path of the strips.
  • the strips are guided through the vaporization enclosure by sliding on support pins (32) arranged at regular intervals and which are mounted very freely in rotation, so as not to modify the conditions of retraction of the bands (figure-4).
  • the retracted bands are wound on a fixed deflection roller (33) and around a motor roller (34) associated with a variable speed motor-reducer assembly (35), intended to compensate the difference in length of the strips between the inlet and the outlet of the shrinking station.
  • the strips (bl - b2) then pass through the drying station (C) to remove the humidity due to vaporization and to perfect the retraction.
  • the strips pass under an oven or an insulating enclosure (36) carried by a frame (37) and equipped with infrared lamps (38) or other similar means ( Figures 6 and 7).
  • the dried strips (bl - b2) are then conveyed to the winding station (D) passing beforehand by the variable reserve device (E), and possibly by a third motor-reducer drive assembly, disposed at the outlet of the oven.
  • variable band reserve device (E) illustrated in FIGS. 1, 2, 11 and 12 comprises a frame (39) whose four uprights (39a) receive a rack (40) with adjustable positioning by angle profiles (41 ).
  • the strips (bl - b2) leaving the oven (36) pass on a deflection roller (48) carried by the rear uprights (39a), then wind successively on the upper rollers (46) and the lower rollers (47) before being routed to the winding station (D).
  • alternating windings are intended to absorb long lengths of strip and ensure continuous running while the strips are being cut and wound.
  • counterweights (49) are suitably tared and connected by flexible link (49a) and pulleys (49b) to the flanges of the carriage.
  • the carriage (42) has a control controlling the speed of the motor-reduction unit (35) to slow it down if the carriage descends, or to accelerate it if the carriage ascends, this to compensate for the advances or delays detected. downstream, that is to say at the level of the conditioning of the wound strips.
  • the bands (bl - b2) pass under a camera (50), with lighting (51) under these bands, responsible for controlling their quality (with storage of the 'location of the defect) and to detect the additions of bands, with a view to eliminating them by winding, as will be seen below.
  • the strips (bl - b2) After passing under the camera, the strips (bl - b2) are directed by an input roller (52) carried by a bracket (53a) of the general frame (53) constituting the station (D), towards the winding means proper ( Figures 13 and 14).
  • the ends of the bands are engaged at the start, between spaced axes (54) which are carried at the end of a spindle (55) associated with a motor-variator-brake (56).
  • Another spindle (57) carrying two spaced axes (58) is also connected to a motor-variator-brake (59).
  • These two drive members are carried diametrically opposite, by a flange (60) linked to a central axis (61) turn nant in a sleeve (62) integral with the frame and connected by a coupling (63) to a rotary actuator (64) ensuring the rotations of the flange according to a half-turn.
  • the upper spindle (55) is rotated on itself, in order to carry out the winding and simultaneously, the rotary actuator (64) is actuated to control the rotation of the flange (60) by one half -turn, in order to bring the spindle (57), therefore the axes (58), in the high position, to produce the next coil.
  • the spindle (55) is stopped (by the brake) with the pins (54) replaced one above the other, and a blade (65) carried at the end of a jack ( 66) secured to the frame (broken lines, Figure 13), is advanced to engage the strips in the axes (58), until the loops thus formed have exceeded said axes.
  • plating cylinders (67) in the form of elastic support (67a) are advanced against the coils formed on the spindle (55).
  • the spindle (57) is then driven in rotation to produce the second winding, while the spindle (55) is also driven to finish winding the end of the cut strips.
  • the plating jacks (67) are moved back and a pallet (71) is engaged by an articulated jack (72), behind the finished coils, in order to evacuate them by the action of another jack (73), on an electronic balance (74) fixed on an independent chassis (75), in order to avoid vibrations.
  • the balance checks the length of the wound tapes by weighing it according to their known density. If the weight does not correspond, a correction is made automatically, by a photo cell (not shown) cooperating with a toothed disc, in order to modify the counting of the teeth by the cell.
  • the identified coil (s) are ejected laterally from the scale, by cylinders (76) in the form of a support, while the correct coils are ejected towards a packaging means, by a pallet ( 77) engaged behind said coils placed on the scale, by an articulated cylinder (78) and a thrust cylinder (79).
  • a device is carried carried by the bracket (14 or 15) secured to the uprights (7a or 8a) of the stores or donors, and on which the rollers are mounted with free rotation. alignment (12 - 13) of the bands (bl - b2), as seen above.
  • the bracket is extended by a support (14a or 15a), the lower end of which carries an alignment roller (80) for the bands (b3 - b4) unrolled from the mat (1 and 3), to fix their free ends fitted with a double sided tape, on a workpiece-catching surface (81) seal the skin type, for example, which may for this purpose take laterally relative 'to its support-guide (82) carried by an arm ( 83) articulated in (84) at the gallows.
  • the arm (83) is also connected by a link (85) to another arm (86) developing behind the alignment roller (13) which is articulated at (87) to the bracket.
  • the arm (83) still carries behind the support guide (82) a support element (88) for a resistance (89); the arm (83) - support (88) assembly, being returned to the rear position by a return spring (90) attached to the extension (14a or 15a).
  • the lower end of the arm (86) carries a resistor (91) and these two resistors are intended to act alternately to cut the end bands of the mat, after hooking up the unrolled bands of the new mats.
  • an electromagnet (92) or other similar means to push fixed on the extension (14a or 15a).
  • the second side of the adhesive ensures the bonding of the waiting strips (b3 - b4), while the arm (86) brought back against the strips ( bl - b2) by the effect of the arm and link joints, allows the resistance (91) which is supplied to cut the strips (bl - b2) behind the bonding
