Definitions

  • an object of the present invention to pro vide an apparatus of the above mentioned type which operates with photoelectric cells and light sources, and in which the precise adjustment of the controls in conformity with the conveyor speed of the folding table can be effected by a simple adjustment of the light source and photoelectric cell, uniformly for all clamping plates arranged in series in a row.
  • FIG. 4 shows the position of the apparatus after the laundry piece has been moved over the light beam of the first control unit so that the light beam is interrupted.
  • PEG. 5 shows the apparatus according to the invention in a position according to which the laundry piece has been placed upon the clamping plate and after the light beam for the second photoelectric cell of the second control unit has been interrupted.
  • FIG. 6 is a cross section taken along the line VI-VI of FIG. 3.
  • FIG. 7 illustrates a cross section of a control unit equipped with a light source and photoelectric cell.
  • control unit housings arranged below the folding table are adjustable and arrestable in the feeding direction. Furthermore, the control units arranged in housings below the clamping plates are adjustable individually in the longitudinal direction of the folding table for releasing all clamping plates arranged adjacent to each other.
  • a still further feature of the invention consists in that between each two control units arranged below the clamping plates, preferably in front of said control units when looking in feeding direction, there is provided a photoelectric control unit serving as preselector, by means of w h a photoelectric cell controlling a clamping plate is connected with a current supply line which behind the relay pertaining thereto leads to the respective directly adjacent photoelectric cell controlling a clamping plate.
  • a photoelectric control unit serving as preselector, by means of w h a photoelectric cell controlling a clamping plate is connected with a current supply line which behind the relay pertaining thereto leads to the respective directly adjacent photoelectric cell controlling a clamping plate.
  • the bridge box is furthermore provided with a plurality of abutmen'is 17 for the clamping plates 15 (see FIGS. 1, 3, 4 and the abutments 17 preferably consisting of elastic material, as for instance rubber.
  • the clamping plates are by means of their arm 13 and bolt 21 pivotally connected to the piston rod w of aizid pressure cylinder 2%
  • a longitudinal adjustment of the piston rod 19 may be effected by a counter nut
  • the piston 23 of the pressure fluid cylinder 29 is continuously acted upon by a spring 2
  • the pre sure fluid cylinder 29 is tiltable about a bolt of a bearing for the folding bridge 13.
  • the actuation of piston 23 by means of compressed air is controlled by a magnetic valve 26 of any standard design.
  • Pressure fluid cylinder 26% and magnetic valve 26 are arranged preferably coaxially with regard to each other.
  • the adjustment of the magnetic valve 26 is effected by a relay 27 which in its turn is controlled by a control unit comprising a photoelectric cell and a light source.
  • the photoelectric cell 29 and a light source 30 are arranged in a housing 28 below the folding table 11.
  • the light source 30 emanates its light beams through a lens 3 1 to a transparent mirror 32.
  • a further lens 33 in the direction 34 the light beams are passed to a reflector plate 35 (FIG. 3) arranged above the folding table 11.
  • the reflector plate 35 for instance a mirror, the light beams, as indicated in FIG. 7 by the arrow 3;" are passed through the transparent mirror 32 and through a lens 37 to the photoelectric cell 2?.
  • lens 37 is provided with a red filter.
  • control unit arranged in housing 28 and comprising the light source, photoelectric cell and lens is arranged ahead of the clamping plate 15, a similar unit arranged in housing 23a is arranged below the clamping plate 15 and the table opening 39 pertaining thereto.
  • the clamping plate 15 may by two superimposed plates 15!; be designed as hollow body so that it will be torsion resistant.
  • the ing plates have their front edges 15a. in ti; ir lower tion arranged at a dis ance above the conveyor belts the fold .c table Ill, w ch distance corresponds in or to at least the thickness of the laundry piece to be folded.
  • the front edges 42a of the wires 42 are located approximately at the height of the front edges 1&1 of the clamping plates and are arranged ahead of the front edges 15a of the clamping plates at a distance corresponding approximately to the thickness of the respective laundry piece.
  • the control of relay 27 either for two adiacent or three adjacent or more clamping plates 15 arranged adjacent to each other in pairs may be actuated by each preselector unit 51, so-called key head.
  • each preselector unit 51 so-called key head.
  • a plurality of clamping plates 15 is made effective or ineffective by the key heads 51 in the circuit of relay 27. in this way it is possible, as already mentioned above, simultaneously to fold either two laundry pieces of the same size, as for instance bed sheets, a narnow laundry piece, such as a towel, together with a particularly wide bed sheet, or also three laundry pieces of approximately the same Width, as for instance three towels.
  • control units 51 serving as preselectors are adjustable individually on the transverse beam 47 and in the longitudinal direction of the table.
  • the preselector unit 51 ma be so arranged that only after afinal advance of the laundry piece 16 onto the clamping plates 15, the final switching on and switching off of the relay for the clamping position will be effected.
  • a folding apparatus for transversely folding laundry articles which comprises: a folding table provided with a plurality of groups of passage means therethrough for the passage of light beams, a plurality of conveyor means arranged above said table and spaced from each other in transverse direction thereof for receiving and conveying laundry articles to be folded, the individual passage means in each said group of passage means in said table being spaced from each other in the direction of movement of said conveyor means and being located laterally between said conveyor means, a plurality of laterally aligned independent clamping means respectively arranged above said conveyor means for temporarily grasping and holding the front portion of the laundry article to be folded, each said clamping means also being provided with passage means therethrough about midway the ends thereof for the passage of light beams, and aligned with one of the individual passage means of one of said groups of passage means, a control unit associated with each of said individual passage means and controllable by laundry articles on said conveyor means in the region of the respective clamping means for controlling the respective one of said clamping means, said control units being respectively arranged below said passage means in said folding
  • an additional control means is provided in the region between each two adjacent individual clamping means and operable in response to movement of a laundry piece into the said region to cause actuation of both of said adjacent individual clamping means in response to the detection of a laundry piece by the control unit of either of the said clamping means.
  • control units below the passage means in said clamping means are individually adjustable in longitudinal direction of said table.
  • a folding apparatus for transversely folding laundry articles which comprises: a folding table provided with passage means therethrough for the passage of light beams, a plurality of conveyor means arranged above said table and spaced from each other in transverse direction thereof for receiving and conveying laundry articles to be folded, said passage means in said table being spaced from each other in the direction of movement of said conveyor means, a plurality of clamping means respectively arranged above said conveyor means for temporarily grasping and holding the front portion of the laundry article to be folded, said clamping means also being provided with passage means therethrough for the passage of light beams, a plurality of control units associated with said clamping means and controllable by laundry articles on said conveyor means for controlling said clamping means, said control units being respectively arranged below said passage means in said folding table and between said conveyor means and including a photoelectric cell and a light source and also a transparent mirror and lens means, some of said passage means in said table being in alignment with the passage means in said clamping means, reflector means respectively arranged above the passage means in said table and in said clamping means,
