  • the present invention relates to an apparatus for treating textile goods in a revolving perforated drum which is enclosed within a stationary housing and the peripheral wall of which is provided with a filling and discharge opening which is adapted to be closed by a door or cover. More particularly, the apparatus according to the present invention is intended for drying and loosening Washed, moist laundry, especially after the same has been spun and pressed to remove the greatest amount of moisture from the washing operation.
  • the known apparatus of this type are each provided with a drum which is open at both ends and rotatable about an inclined axis.
  • the textiles to be treated are inserted into this drum at the upper end and removed therefrom at the lower end.
  • hot air is passed into the drum through the perforated wall thereof.
  • These prior apparatus are rather inefficient, especially because of the insufficient utilization of the hot air, and they have also the disadvantage that, because of the rotation of the drum, longer textile pieces will be twisted together while emerging from the drum, and that the textiles will not be completely dried.
  • Another known apparatus of this type which is designed according to the principles of a concrete mixer and is used for loosening laundry has the disadvantage that it can only be filled and emptied by hand. Also, the cover of this drum is pivotable to the outside.
  • Another object of the present invention is to provide such an apparatus which permits the various operating steps thereof to be carried out partly automatically and partly by hand by a few very simple control movements, or entirely automatically according to a preset program.
  • the present invention provides a perforated drum which is rotatable about a horizontal axis and the peripheral wall of which is provided with an opening which is adapted to be closed or opened by a curved door which is automatically moved by the cooperation of control elements which are rotatable with the drum with other control elements which are stationary, and wherein these control elements, in turn, are controlled by a reversal of the direction of rotation of the drum so that the door will be closed when the drum rotates in one direction and opened when it rotates in the opposite direction.
  • the mentioned door may extend over the entire length of the drum and it may also be designed so as to be either slidable in the peripheral direction of the drum or to be pivotable into the drum about an axis extending longitudinally along the peripheral wall of the drum.
  • the opening and closing movements of the curved door may be effected by at least one driving mechanism which is mounted on one end wall of the drum and is controlled by a camlike member which is mounted on and rotatable with the drum.
  • a driving mechanism which is mounted on one end wall of the drum and is controlled by a camlike member which is mounted on and rotatable with the drum.
  • a resilient control lever which is mounted on the stationary housing of the drum and extends into the path of movement of the cam will then be pivoted by the cam from one end position to the other end position whereby the driving mechanism will be controlled to operate in one or the other direction.
  • This driving mechanism may be designed in the form of a pneumatic or hydraulic cylinder and piston unit.
  • the operating medium for this unit may be supplied to the drum by operatively associated elements which are disposed coaxially with the drum and one of which is rotatable with the drum, while the other element is mounted on the stationary housing.
  • the driving mechanism of the curved door may, however, also consist of an electric motor or by one or two solenoids which are supplied with current in the usual manner through the shaft of the drum by means of slip IlllgS.
  • the housing of the apparatus is provided with a discharge opening adjacent to the lower side of the drum. According to one preferred embodiment of the present invention this discharge opening may be closed or opened by a slide cover which may be controlled by a second driving mechanism. Underneath the discharge opening of the housing a conveying mechanism is preferably provided in the form of an endless conveyor belt which is adapted to receive the treated textiles when they are discharged from the drum and to convey them out of the housing to a suitable point away from the apparatus.
  • a discharge trough which covers the discharge opening of the housing when is is in its normal position and is adapted to be moved by swivel arms and roller tracks to a position outside of the housing in which it will then be tilted over to discharge the treated textiles, for example, upon a table.
  • the upper part of the housing is provided with a filling opening which may be brought into alignment with the opening of the drum which may be closed by the curved door, and this filling opening of the housing may also be closed by a cover.
  • the present invention further provides a trough for filling the textiles to be treated into the drum.
  • This filling trough may be pivoted from an inoperative position in a recess in the lower part of the housing to a position laterally adjacent to the housing, in which the opening of this trough is disposed at its upper side so as to permit the trough to be filled. Thereafter, the trough may be pivoted further upwardly to a position above the filling opening of the housing and during this part of the pivoting movement the trough will be automatically tilted so as to fill the textiles into the drum through the aligned filling openings in the housing and drum.
  • the cover of the filling opening of the housing and the filling trough are both controlled by one driving mechanism in such a manner that the cover will be automatically opened when the trough approaches the filling opening and closed when the trough moves away from the filling opening.
  • the air current which is discharged therefrom during its operation usually contains foreign substances such as threads, fibers, fuzz, and the like which are severed from the materials during the treatment. If the air is sucked through the apparatus and no special provision is made to prevent this, these foreign substances will pass into the suction mechanism and if an air strainer is provided in front of it, they will clog up this strainer very quickly and thereby reduce the eificiency of the suction mechanism or even render it entirely ineffective.
  • the present invention provides a special air filter which consists of a cylindrical sieve which is rotatably mounted and provided with one or more stationary brushes which are adapted to wipe the cylindrical surface and interstices of the sieve.
  • This cylindrical sieve is preferably combined with the suction fan to form a structural unit.
  • this air filter may be designed so that the shaft of the cylindrical sieve will be driven intermittently by a motor or by the driven part of an overriding clutch, the driving part of which is connected to the control mechanism for operating the cover of the" housing which closes the filling opening thereof.
  • the cylindrical sieve will be turned for apart of One revolution, while at the same time the suction fan will be stopped so that the foreign substances on the outer surface of the sieve will not be drawn tightly against the sieve but only adhere loosely thereto.

  • the direction of rotation of the drum 2 is reversed, so that the door 8 will be opened.
  • the opening of the drum is then brought into alignment with the discharge opening 15.
  • the four-way valve 136 is then actuated to pull the slide cover 16 to its open position so that the opening will be opened permitting the textiles to fall upon the conveyor belt 17 which will carry them out of the apparatus.
  • the treated textiles will drop into the discharge trough 71 which is moved to the discharging position according to FIG. 11, when the motor 89 is switched on, whereby pipes 84 are rotated about their axes so that the spindles 83 will be screwed outwardly to pivot the swivel arms 7 8 outwardly and then upwardly.
  • the rollers 73 and 75 will then at first run slightly downwardly along the rail portions 74a and 740, whereby the trough 71 will be moved away from the opening 15, and they will thereafter run upwardly along the Wide rail portion 74b until the rollers 75 are arrested by abutting against the stops 76, as shown in FIG. 10.
