Abstract
On leaving a dry pressing or ironing machine, each piece of linen or washing is folded on a folding arm performing a reciprocating movement. The folding arm then bears on an entrance end of a conveyor (28), which is then driven (F2), so as to move the folded piece of linen towards a recovery tank. A freewheel mechanism (52) is simultaneously brought into a disengaged state, which has the effect of lowering a pressing roller (40) and rotating the latter by means of a belt (62). Driving the conveyor (28) in the reverse direction (F3) then brings the pressing roller (40) into the raised position, by means of the freewheel (52), a crank (54) and a rod (56).
Claims6
Device for folding and discharging linen, which is to be installed downstream of a linen exit area on a dry pressing machine, said device being characterized in that it comprises:
- a conveyor, whose entrance end is to be placed substantially facing said exit area, said conveyor being able to move in one or other direction under the action of drive means,
- a folding arm, whose upper end can perform a reciprocating movement between two extreme positions located beneath the exit area and on either side of the latter under the action of control means, one of these extreme positions corresponding to a bearing of the folding arm against the entrance end of the conveyor,
- a pressing roller displaceable between a lower position, where it rests by gravity on the entrance end of the conveyor, and an upper position, under the action of a mechanism permanently linking the pressing roller with the drive means, via unidirectional engagement means, which are disengaged in order to maintain the pressing roller in the lower position, when the conveyor passes in a linen discharge direction, and engaged for bringing the pressing roller into the upper position when the conveyor moves in the reverse direction.
Drive pressing machine comprising:
- a rotary pressing cylinder,
- at least one endless belt, in contact with the cylinder over part of its circumference, so as to define a linen entrance area and exit area,
- a conveyor, whose entrance end is to be placed substantially facing said exit area, said conveyor being able to move in one or other direction under the action of drive means,
- a folding arm, whose upper end can perform a reciprocating movement between two extreme positions located beneath the exit area and on either side of the latter under the action of control means, one of these extreme positions corresponding to a bearing of the folding arm against the entrance end of the conveyor,
- a pressing roller displaceable between a lower position, where it rests by gravity on the entrance end of the conveyor, and an upper position, under the action of a mechanism permanently linking the pressing roller with the drive means, via unidirectional engagement means, which are disengaged in order to maintain the pressing roller in the lower position, when the conveyor passes in a linen discharge direction, and engaged for bringing the pressing roller into the upper position when the conveyor moves in the reverse direction.
