Definitions

  • the present invention relates to a device allowing the insertion of pieces of linen, such as sheets, in particular in an ironing machine. More particularly, this device is of the type of those comprising a conveyor at the upstream end of which is provided at least one pair of grippers, movable transversely to the direction of advance of the conveyor, and capable of gripping a piece of laundry by two of its angles, means being provided for driving the two clamps of each pair, in order to separate them from one another in order to tension the piece of laundry grasped, and to bring this piece of laundry into position centered by relative to a defined axis of advance, which is not necessarily the axis of the conveyor.
  • the present invention overcomes this drawback by providing an improved device, of the kind defined above, in which the drive means of the two clamps of each pair are arranged so as to move, in a first phase, a single clamp up to that the piece of laundry is stretched, and then simultaneously move the two clamps, in a second phase, until bringing them in a symmetrical position relative to the centering axis under the control of means detecting the movement of the first clamp and reacting to the tensioning of the piece of laundry.
  • the means for detecting the displacement of the first clamp translate this displacement into pulses, exploited using a counter which counts one pulse out of two during the first phase, that is to say between the start of the first clamp and the instant when the piece of laundry is stretched, and which counts all the pulses during the second phase, that is to say from the moment when the piece of laundry is stretched and when the second clamp is also driven, the content of the counter being compared with a fixed value such that at the time when equality is obtained, the two clamps have reached their symmetrical position with respect to the centering axis.
  • the counter can operate by counting down, and in this case it is advantageous to provide that its initial content is equal to the difference between, on the one hand, the distance separating the rest position of the second clamp and the centering axis, and on the other hand, half of the initial spacing of the two clamps, so that the centering is obtained at the precise instant when the content of the counter cancels out, as will be demonstrated below.
  • the means for detecting the displacement of the first clamp consist, for example, of an optical pulse generator, associated with the drive means of this first clamp.
  • the two clamps of the same pair are driven by means of endless transmission elements, from two separate motors, the optical pulse generator being mounted so as to detecting the movement of the transmission element causing the first clamp, while the second clamp cooperates, in the rest position, with a presence detector. This detector reacts, to modify the counting mode of the pulses, at the moment when, the sheet being stretched, the first clamp begins to pull the second through the sheet.
  • the two clamps can be connected, in particular by means of endless cables passing over idler pulleys, to two electric brake motors.
  • only the first clamp of each pair is driven, by means of an endless transmission element, from a motor, the second clamp being provided with means allowing its locking on said transmission element, during the second operating phase.
  • the drive system can thus be further simplified.
  • the device visible in FIG. 1, intended to supply laundry items, such as sheets, an ironing machine placed downstream, not shown, comprises a conveyor 1 bringing the laundry items to said machine.
  • pressure discs 2 and especially two pairs of pliers 3, 4 and 5, 6 are provided, located upstream of the rear end of the conveyor 1. All these clamps 3 to 6 are movable transversely to the direction of advance of the conveyor 1, along a sliding rail 7 (see FIG. 2), and the present invention is more particularly concerned with the mechanism drive these pliers.
  • Each of the clamps 3 to 6 consists of a carriage 9 rolling on the rail 7, and two jaws 10 constituting the clamp itself, designed so as to be able to tighten for example the angle of a sheet.
  • the carriage 9 of the clamp 3 is secured with an endless drive cable 11 shown in dotted lines. This cable 11 passes over various return pulleys 12 to 17, as well as over a drive pulley 18 coupled to a first brake motor 19. Similarly, the carriage 9 of the clamp 4 is secured with an endless drive cable 20 , shown in phantom; this cable 20 passes over various return pulleys 21 to 26, as well as over a drive pulley 27 coupled to a second brake motor 28.
  • the cable 11 used to drive the clamp 3 passes over an additional pulley 29, coupled to an optical pulse generator 30.
  • This generator associated with an electronic pulse counter, measures the movement of the cable 11, therefore the clamp 3.
  • the other clamp 4 cooperates with an electrical contact 31 placed at the end of the rail 7, and detecting the presence or absence of this clamp 4 at its stop station.
  • the two motors 19 and 28, the generator-pulse counter 30 and the presence contact 31 are connected to a central control unit 32.
  • the operator introduces two angles of the sheet into the jaws 10 of the two clamps 3 and 4, initially stored near the left end of the rail 7.
  • the brake motor 19 is started, while the engine brake 28 is released.
  • the clamp 3 is thus moved, in the direction of its distance from the clamp 4 which initially remains stationary, at its stop station.
  • the sheet therefore deploys and, when stretched, it starts to drive the clamp 4 which then leaves its stop position and causes the actuation of the presence contact 31.
  • the motor 28 starts up for a very short time, to give its speed to the clamp 4.
  • the clamp 3 then drives the clamp 4, by means of the stretched sheet, until the two clamps 3 and 4 are centered, that is to say arrive in positions in principle symmetrical with respect to the axis 8.
  • the two motors 19 and 28 are, at this time, braked so as to immobilize the two cables d drive 11 and 20, as well as the two clamps 3 and 4, and the sheet is itself centered, in the stretched position. This sheet can then be spread on the conveyor 1 and separated from the jaws 10.
  • the content of the pulse counter is initially equal to a preset value P.
  • a countdown begins and is carried out as follows: content C of the counter decreases by one for the reception of two pulses from the optical pulse generator 30.
  • the content of the counter is given by the formula:
  • the contact 31 for the presence of prince 4 causes, at this instant, a change in the countdown mode: all the pulses emitted by the generator 30 are counted down, therefore the content of the counter is given by the formula:
  • the motor 28 of the second clamp 4, as well as the corresponding drive cable 20 are eliminated.
  • This clamp 4 is then provided with mechanical locking means on the drive cable 11 of the first clamp 3, these means being triggered when the second clamp 4 begins to be pulled by the first clamp 3, by means of the stretched sheet .
  • the principle of measurement by pulse counting is not changed.
  • This variant has the advantage of allowing the second clamp to be automatically locked, when it leaves its stop station, and it also allows said clamp to unlock itself, when it returns to the station. stop.
  • the two clamps are thus driven by a single mechanism, which provides a very great simplification in comparison with the existing systems, and which always allows automatic operation, including to return the two clamps to their starting position.
