Definitions

  • the invention relates to an apparatus for folding a flat piece of laundry, such as a tablecloth, comprising feeding and discharging means for the piece of laundry, first and second auxiliary conveying means for the piece of laundry arranged consecutively in the supply direction of the piece of laundry near the feeding and discharging means, and first and second direction changing means for the piece of laundry to direct the piece of laundry over the first and the second auxiliary conveying means.
  • the invention also relates to a method for folding a flat piece of laundry with the help of the apparatus according to the invention.
  • a suchlike apparatus is known and is marketed by the applicant, so that laundries, for instance, can fold flat linen, such as tablecloths or sheets, twice in half after washing and mangling.
  • the cloth is fed with the help of feeding and discharging means and when the front edge reaches the first auxiliary conveying means it is lead by the first direction-changing means over the first auxiliary conveying means.
  • the first direction-changing means are deactivated and the direction of movement of the first auxiliary conveying means is reversed, so that the cloth is conveyed between the feeding and discharging means and the first auxiliary conveying means folded in half upon itself and is carried along by the feeding and discharging means.
  • This known apparatus has the disadvantage that the laundry can only be folded once or twice in half or be provided with a French fold.
  • the apparatus comprises means able to hold the piece of laundry against the first auxiliary conveying means.
  • the holding means By arranging the holding means it is possible to hold a piece of laundry, the front portion of which has in part already passed the first auxiliary conveying means, behind this front portion against the first auxiliary conveying means, as a result of which the first auxiliary conveying means can pull back the front portion of the piece of laundry counter to the direction of movement of the feeding and discharging means and can guide it onto the first auxiliary conveying means, so that a double-folded portion of the piece of laundry is made on the first auxiliary conveying means.
  • the holding means it is therefore possible to fold the piece of laundry in an alternative manner, for instance in a W-shaped fold, as will be described below. It is therefore possible with the invention either to obtain a piece of laundry which is folded over twice or provided with a French fold in the known way, or, alternatively, to obtain a piece of laundry folded in a W-shape.
  • the holding means are formed by pressure means so as to press the piece of laundry against the first auxiliary conveying means, which pressure means preferably comprise a pressure roll, to press the piece of laundry against the first auxiliary conveying means without slipping.
  • the pressure means comprise a double-acting pneumatic cylinder in order to press the pressure roll against the first auxiliary conveying means as desired, so that the pressure roll can be activated or deactivated quickly and at the correct moment.
  • the pressure means are preferably arranged at the location at which the first auxiliary conveying means approach closest to the feeding and discharging means, so that they can be arranged at the other side of the feeding and discharging means with regard to the first auxiliary conveying means and do not obstruct the transit of a piece of laundry.
  • the invention also relates to a method for folding a flat piece of laundry, such as a tablecloth, in the shape of a W, with the help of an apparatus according to any one of the preceding claims, the following steps being performed:
  • the method is preferably carried out with an apparatus according to the invention which is provided with first and second blowing means according to claim 6, in which at the start of step c an air pulsation is applied to the piece of laundry with the help of the first blowing means and in which at the start of step f an air pulsation is applied to the piece of laundry with the help of the second blowing means, so as to press the piece of laundry on the respective auxiliary conveying means, so that the piece of laundry is carried along with certainty when reversing the direction of movement of the auxiliary conveying means and the piece of laundry will not slip or slide over the auxiliary conveying means.
  • Figure 1 shows a preferred embodiment of the folding apparatus according to the invention in side view.
  • the figures 2 to 5 show the folding apparatus according to figure 1 at various stages of the folding process of a piece of laundry.
  • FIG. 1 shows the preferred embodiment of the folding apparatus 1 according to the invention in side view.
  • the folding apparatus 1 consists of feeding and discharging means 10, first auxiliary conveying means 30, second auxiliary conveying means 40, direction-changing means 20 and blowing means 50 and 51.
  • the feeding and discharging means 10 consist of endless belt strips 11, of which a great number are led in a parallel and spaced fashion over guide rolls 12. During operation the belt strips 11 are driven by a driving apparatus, not shown, at a constant speed in the direction shown by arrow A.
  • the first auxiliary conveying means 30 consist of a frame 35 with end rolls 32 and 33 on two opposite ends, about which an endless conveyor belt 31 is arranged. During operation the end rolls 32 and 33 are driven by a driving apparatus 34, and the endless conveyor belt 31 is also driven thus.
  • the endless conveyor belt 31 is movable in two directions according to arrow B.
  • the end roll 32 is arranged in the direct vicinity of the belt strips 11, in such a way that a piece of laundry can pass without difficulty between the belt strips 11 and the conveyor belt 31 over the end roll 32.
  • the second auxiliary conveying means 40 are identical to the first auxiliary conveying means 30, the reference numerals of corresponding components being increased by 10.
  • the first direction-changing means consist of a frame 22 with guide fingers 21 on it, in which a double-acting pneumatic cylinder 23 can swivel the frame 22 around a swivelling point between a position in which the fingers 21 are contained under the belt strips 11, as in figure 1, and a position in which the guide fingers 21 project obliquely between the belt strips 11.
  • the second direction-changing means with the guide fingers 24, the frame 25 and the cylinder 26 are correspondingly made.
  • the direction-changing means are placed such that when the guide fingers project obliquely between the belt strips 11, a piece of laundry is led to the first or second conveyor belt 31 and 41, respectively.
  • the blowing means 50 and 51 respectively comprise a blow pipe with openings through which air can be blown in the direction of the transition between the belt strips 11 and the conveyor belt 31 and the conveyor belt 41, respectively.
  • the blow pipes are attached in a non-described manner to the frame of the apparatus which is not shown.
  • a pressure roll 27 is arranged which is swivable with the help of a double-acting pneumatic cylinder 28 with which the pressure roll can be placed in a position in which it is spaced under the belt strips 11, and a position in which not specifically shown circular grooves on the driving roll 27 press against the end roll 32 of the first auxiliary conveying means 30 in between the belt strips 11.
  • the second blow pipe 51 applies an air pulsation in order to press the front portion of the cloth against the second conveyor belt 41, so that this portion is carried along with certainty when reversing the direction of movement and the risk that it slips or slides over conveyor belt 41 is avoided.
  • control of the apparatus is executed by control means known per se, while the apparatus can be provided with sensors (not shown) for detecting the front or rear edge of the piece of laundry, for instance.
