Definitions

  • the present invention relates to an apparatus for spreading and feeding of articles of flatwork comprising a conveyor, at the upstream end of which a beam with a pair of clamps is supported, the clamps being suited to hold a corner of an article each and to move apart until the edge of the article is tight and thereafter release the article onto the conveyor.
  • the beam is adapted to be reciprocated in such a way that the article during its insertion with the corners in the clamps is freely suspended in front of the conveyor, but when released is placed over the upstream end of the conveyor.
  • the clamps thereby perform a complex combined movement, being at first moved apart and thereafter moved in synchronization with the conveyor, over which the releasing takes place at the end of the latter movement. For this combined movement a certain amount of time is consumed in which the operator is not able to insert another article.
  • the complicated construction of the reciprocable beam and the considerable movable masses in it it is a drawback for the operator to see the beam reciprocate just in front of him or her.
  • the apparatus is characterized in that above the upstream end of the conveyor and below the beam a plate is arranged, said plate being reciprocable from a first position in which the upstream end of the conveyor is covered and a second position in which the interspace between the beam and the conveyor is free.
  • the plate is in its first position and stays in this position during the moving apart of the clamps.
  • the upper edge of the article is tight and the article is suspended over the edge of the plate, it is moved quickly to the second position simultaneously with the releasing of the clamps.
  • the article will then drop partly on the conveyor and partly on the plate, the latter of which will, however, during its movement transfer and smoothe the leading edge of the article upon its delivery to the conveyor.
  • the movement of the plate takes place with a speed, which according to the invention is substantially greater than the speed of the conveyor.
  • the clamps are moved together and the plate returns to its first position, and the apparatus is ready for a new cycle.
  • the apparatus will be more comfortable for the operator.
  • a pair of belts are usually provided in front of the conveyor, the outward facing parts running from the center of the apparatus to the sides.
  • the plate has a third position behind the first one and into which the plate is moved during the moving apart of the clamps, and in which third position the conveyor is covered, whereas the oppositely-moving belts are free.
  • this drawback has been eliminated in an embodiment, in which a roller is placed in front of the upstream edge of the conveyor and provided with driving means, said means being arranged to rotate the roller during the releasing of the clamps in a direction opposite the conveyor over a predetermined angle and thereafter to rotate the roller synchroneously with the conveyor.
  • the roller in front of the conveyor will prevent the weight of the article hanging freely in front of the apparatus from slipping out of the apparatus, and by the opposite rotation it will pull the article out of the clamps without folds.
  • the roller is driven with a speed, which is substantially synchroneous with the conveyor, whereby the article will be transported without folds by the conveyor.
  • the apparatus comprises as shown in Fig. 1 a frame with side plates 1 connected at their upper edges by means of a beam 2. Between the side plates a conveyor 3 is mounted, on which conveyor articles of flatwork is spread and fed into a subsequent treatment, for example in an ironing machine or folding apparatus. On the beam a pair of slidable clamps 4,4' are mounted, each adapted to receive a corner of the article to be spread out and transferred to the conveyor 3. The two clamps are arranged to move apart along the beam 2 after the insertion of the article until the edge of the article is drawn tightly and thereafter to release the article.
  • a slidable plate 5 is arranged, which during the insertion of the article may serve as a working surface and onto which the article after being spread out is transferred.
  • the plate 5 is adapted to perform a quick movement in the direction of the conveyor, by which movement the space under the beam is made free, whereby the article falls down onto the conveyor.
  • the plate may be returned to the first position over the article, which is transported on the conveyor 3 under the plate.
  • the clamps 4,4' have returned to the position close to each other, the operator may insert another article in the clamps, even if the trailing edge of the first article has not passed under the plate.
  • a pair of oppositely driven belts 6,7 is arranged, the portions facing outwards running from the center to the sides.
  • Fig. 2 the apparatus is ready for the insertion of the corners of the article of flatwork in the pair of clamps 4.
  • the plate 5 is in its first position, in which its front edge is in front of the conveyor 3 and the pair of belts 6,7.
  • the apparatus starts the spreading procedure.
  • the plate 5 is moved a short distance in the direction of the conveyor as shown in i Fig. 3, in which an article is inserted in the clamps, in order to free the belts, which are uncovered by the front edge of the plate.
  • the pair of clamps 4 are moved apart until the edge of the article is drawn tightly.
  • Sensing means for example a photo cell, detects when the upper edge of the article is drawn tightly and releases the clamps 4, dropping the article T on the plate 5,which thereafter performs a quick movement backwards over the conveyour 3, thereby transferring the article to the conveyor as shown in Fig. 4.
  • the plate immediately thereafter returns to the first position - the starting position - the clamps being simultaneously moved together at the center.
  • Fig. 5 a driving arrangement for the pair of clamps 4 is shown. It may be preferred that the path of the clamps forms an angle allowing the clamps to be situated further up the conveyor when moved apart than in the position, wherein the insertion takes place.
  • the clamps in the pair of clamps 4 are fastened to different portions of a cable loop 8, which is quided by a number of freerunning pulleys 9 in such a way that the clamps move symmetrically in respect of each other.
  • the cable is further passing over a number of freely running pulleys arranged on a slide 10 in such a way that a conversion ratio is obtained between the movement of the slide and the pair of clamps.
  • the slide may be driven by means of for example a pneumatic cylinder 11.
  • Fig. 6 a longitudinal section through a modified apparatus according to the invention is shown.
  • the construction corresponds to the apparatus described above, apart from a roller 12 arranged in front of the upstream edge of the conveyor.
  • the other parts correspond to the elements in the above apparatus and consequently have the same reference numbers.
  • the roller 12 is arranged to be driven substantially synchroneously with the conveyor, which may be arranged by a common chain driving the roller via a friction clutch.
  • the roller is furthermore arranged to be stopped and to be driven through a predetermined angle in the opposite direction.
  • the driving means for this opposite drive may be a brake, the moment arm of which is provided with driving means for the opposite drive, for example by connecting the moment arm 13 with the frame by means of a pneumatic cylinder 14.
  • the operation of the apparatus according to the invention is that the roller 12 is stopped after the clamps 4 have moved apart.
  • the plate 5 is moved a short distance in the direction of the conveyor, whereby the roller is uncovered, said roller is rotated oppositely through an angle corresponding to a linear movement of 2 - 10 cm.
  • the clamps are simultaneously released, the article T dropping onto the plate 5 when the plate is reaching the position in which the interspace between the beam and the conveyor is free, the synchroneous drive of the roller 12 is started, the article being conveyed through the apparatus.
  • the plate is then.returned to its starting position, while the trailing edge of the article is transported under the plate 5 as described above in connection with the Figs. 1 - 4.
