Definitions

  • This invention relates to an apparatus for loading flat articles of clothing into a laundry processing unit, such as an ironing or folding machine, flat clothing being understood to mean table and household linen, and hospital and catering linen etc., such as table cloths, napkins, sheets, towels, and others.
  • a loading method that can be implemented using the above apparatus.
  • processing units such as ironing and folding machines for clothing are used, into which the flat articles of clothing must be introduced in a spread out condition on a mobile conveyor belt.
  • apparatuses are known for loading flat articles of clothing into such laundy processing units.
  • Patent EP-A-0554205 describes one of such loading apparatuses, including a frame with an entrance opposite one reception end of a conveyor belt and one or more loading posts located in front of said entrance.
  • Each loading post is controlled and served by an operator, and includes a first pair of clamps in which said operator can catch the ends of a flat article of clothing, and lifting means adapted to move said first pair of clamps, with the article of clothing hanging down, to a higher position in which the first pair of clamps transfers the ends of the flat article of clothing to a second pair of clamps associated with the spreading out means mounted on the frame.
  • Said spreading out means includes a pair of carriages running on respective guide rails extending above and next to the reception end of the conveyor belt transverse to the transport direction thereof.
  • Each clamp in said second pair of clamps is mounted on one respective carriage of said pair of carriages, and a driving means is configured and arranged to move each carriage independently, separating them from one another, between positions in front of the loading post, where the transfer took place, and suitable positions with respect to the centre of the conveyor belt in order to spread out the flat article of clothing sufficiently.
  • the flat article of clothing is held by the top ends thereof by the second pair of clamps and hangs down vertically. Blowing and suction means help to place one end of the flat article of clothing spread out over said reception end of the conveyor belt at the same time as the second pair of clamps release the article.
  • the trajectory of the said movement of said first pair of clamps to a higher position is a tilted rectilinear trajectory, with a loading end positioned at a lower level and more external that the opposite transfer end.
  • both clamps in the first pair of clamps simultaneously carry out translation movements along parallel trajectories from the loading position to the transfer position and subsequently translation movements in the opposite direction upon returning to the loading position.
  • An aim of this invention is to provide an apparatus and a method for loading flat articles of clothing into a laundry processing unit including the above-mentioned improvements regarding speed and ergonomic design.
  • an apparatus for loading flat articles of clothing into a laundry processing unit such as an ironing or folding machine, of the type including a frame having an entrance opposite one reception end of a conveyor belt, at least one loading post controlled by an operator, with a first pair of clamps in which said operator can catch the ends of a flat article of clothing, and lifting means adapted to move said first pair of clamps to a higher position in which the flat article of clothing is transferred to a second pair of clamps associated with spreading out means including at least one pair of carriages running along respective guide rails transverse to the transport direction of said conveyor belt, each clamp in said second pair being mounted on a respective carriage of said pair of carriages, driving means being arranged to move each carriage in said pair of carriages independently, separating them from one another, between positions in front of the loading post, of which there is at least one, and suitable positions with respect to the centre of the conveyor belt to place one end of the flat, article of clothing stretched out on said reception end of
  • the apparatus is characterised in that said lifting means for moving said first pair of clamps in the loading post include at least one pivoting arm supporting at one end the first pair of clamps and which is connected at the other end in a pivoting manner to a slide slidably mounted on one or more rectilinear guide rails having one end higher than the other, rotating driving means for the pivoting arm and translation driving means for the slide being arranged and adapted to move the first pair of clamps in a combined translation and rotation trajectory.
  • the apparatus also includes a suction device having a suction mouth adjacent to a lower part of the reception end of the conveyor belt to attract the flat article of clothing by means of a suction jet towards said reception end of the conveyor belt and towards a longitudinal roller located next to a lower edge of said suction mouth.
  • Said longitudinal roller is driven to rotate at a relatively high speed so as to cooperate with the suction device and quickly drag the hanging part of the article of clothing into a box of the device from where the article of clothing is dragged by the conveyor belt while mobile brushes moving longitudinally in divergent directions next to the suction mouth remove any possible wrinkles from the article of clothing.
  • the method includes the conventional steps of: manually catching the ends of a flat article of clothing in a first pair of clamps arranged in at least one loading post controlled by an operator; moving said first pair of clamps towards a higher position using lifting means associated with said loading post; transferring the flat article of clothing to a second pair of clamps associated with spreading out means including at least one pair of carriages running on respective guide rails transverse to the transport direction of said conveyor belt, each clamp in said second pair of clamps being mounted on one respective carriage of said pair of carriages; spreading out the flat article of clothing by means of the independent movement, produced by driving means, of the pair of carriages, separating them from one another, between positions in front of the loading post, of which there are at least one, and symmetrical positions with respect to the centre of the conveyor belt; and placing one end
  • the method of the invention is characterised in that the said step of moving the first pair of clamps to a higher position using said lifting means includes moving the first pair of clamps in a combined translation and rotation trajectory by means of at least one rotation, produced by rotation driving means, of at least one pivoting arm supporting at one ends the first pair of clamps, and at least one translation, pproduced by translation means, of a slide slidably mounted on rectilinear guide rails and to which the pivoting arm is connected at its other end.
  • the combined translation and rotation trajectory of the first pair of clamps allows a greater overall movement of the first pair of clamps than with just a translation or just a rotation movement, whereby the loading position is further away from the transfer position and therefore further away from the reception end at the entrance to the frame. Also, the greater movement of the combined trajectory can be produced proportionally more quickly than an equivalent movement with just translation.
  • the combined translation and rotation trajectory allows the first pair of clamps to go beyond the second pair of clamps immediately after transferring the flat article of clothing so that the second pair of clamps start to move without having to wait for the first pair of clamps to return to the loading position, which means an additional saving in time.
  • the combined translation and rotation trajectory means that the first pair of clamps support the article of clothing in a raised waiting position, after the translation and before the rotation, so that the article of clothing remains uninfluenced by the suction device associated with the conveyor belt.
  • various operating units of the apparatus of this invention are incorporated in a series of modular units provided with pivoting and/or collapsible driving means to enable different operating modes and also to allow a folding operation conferring a suitable apparatus volume that is appropriate for being packaged in a box of degradable or reuseable material, such as wood, adapted to be introduced into a standard container.
  • the apparatus includes a frame 1 with an entrance opposite a reception end 31 of a conveyor belt 30 (see also Figs. 2 , 4 and 5 ).
  • each loading post 2 includes a first pair of clamps 3, 4 in which the corresponding operator can catch adjacent ends of a flat article of clothing.
  • Lifting means associated with each loading post 2 are adapted to move said first pair of clamps 3, 4, with the article caught in said clamps, to a higher position in which the flat article of clothing is transferred to a second pair of clamps 5, 6 associated with spreading out means (shown in dotted lines in Fig.
  • each clamp 5, 6 is mounted on one respective carriage of said pair of carriages 7, 8, and driving means are arranged to independently move each carriage 7, 8 and respective second clamps 5, 6 along their respective guide rail 9, 10. This movement is produced under the guidance of an electronic control programmed to move second clamps 5, 6, in which respective ends of the article of clothing transferred from the first pair of clamps 3, 4, are caught, separating them from one another, between positions in front of the loading post 2 in question, where the transfer takes place, and suitable positions with respect to the centre of conveyor belt 30, so that the article of clothing is spread out and hung vertically.
  • blowing and suction means including a bar 61 mounted on pivoting arms and provided with suction holes and a endstop bar 62 mounted on pivoting arms and provided with blowing nozzles.
  • the apparatus includes only one pair of guide rails for a single second pair of clamps, according to this invention it would be possible to include two or more pairs of guide rails for an equal number of pairs of second clamps adapted for independently serving different loading post units.
  • the said lifting means arranged to move said first pair of clamps 3, 4 in loading post 2 include a pivoting arm 11 supporting at one end the first pair of clamps 3, 4. Said arm 11 is connected in a pivoting manner at the other end to a slide 12 slidably mounted on one or more rectilinear guide rails 13, generally tilted, with one end being higher than the other.
  • the lifting means includes rotation driving means for rotating pivoting arm 11 in both directions with respect to slide 12 and translation driving means for moving slide 12 along guide rails 13 in both directions. This way, the rotation and translation driving means is adapted to move the first pair of clamps 3, 4 in a combined translation and rotation trajectory.
  • Figs. 3A-3D said combined trajectory of the first pair of clamps 3, 4 is described during a loading cycle.
  • slide 12 is positioned at the lower end of guide 13 and pivoting arm 11 is in an initial position extending downwards.
  • the first pair of clamps 3, 4 (only one of which is shown in Figs. 3A, 3D ) is in a suitable ergonomic position for an operator to be able to comfortably catch two adjacent ends of a flat article of clothing, each in a respective clamp of the first pair of clamps 3, 4.
  • the rotation driving means of pivoting arm 11 and the translation driving means of slide 12 are ready to start, following an order from the operator, a sequence of operations for producing the following movements.
  • slide 12 makes a first movement, pivoting arm 11 being in an initial position extending downwards, from a lower or loading position ( Fig. 3A ) to an upper or transfer position ( Fig. 3B ).
  • the flat article of clothing A is dragged upwards and hangs vertically.
  • pivoting arm 11 makes a first rotation from the said initial position to a final position extending upwards and inwards ( Fig. 3C ) while slide 12 remains is said transfer position.
  • this first rotation of the pivoting arm takes place while the second pair of clamps 5, 6 is in a reception position, which is suitably related to the trajectory of the first pair of clamps 3, 4 so that the flat article of clothing A is automatically transferred from the first pair of clamps 3, 4 to the second pair of clamps 5, 6 during said first rotation of pivoting arm 11.
  • the first and second pairs of clamps are driven in a conventional manner during the transfer and the description thereof is omitted.
  • the transfer takes place in a predetermined position (indicated in dotted lines in Fig. 3C ) during the first rotation of pivoting arm 11, when the pivoting arm has performed only a part of its first rotation.
  • pivoting arm 11 reaches the final position after the transfer (indicated in solid lines in Fig. 3C )
  • the first pair of clamps 3, 4 reaches a position beyond the position of the second pair of clamps 5, 6.
  • slide 12 can start a second translation movement, in the opposite direction, but maintaining pivoting arm 11 in said final position ( Fig. 3D ).
  • the trajectory of the first pair of clamps 3, 4 (the maximum position of which is indicated by solid lines in Fig. 3D ) is free from interferring with the second pair of clamps 5, 6 during said second translation movement of slide 12 from the transfer position to the new loading position.
  • the second translation movement can be performed irrespective of the position of the second pair of clamps.
  • pivoting arm 11 performs a second rotation in the opposite direction, from the final position to the starting position again.
  • This second rotation can be performed during the second translation movement of slide 12 and once the position of the first pair of clamps 3, 4 has passed the position of the second pair of clamps 5, 6, or once slide 12 has reached the loading position, in which case a pressure regulator regulates the operating pressure of a cylinder 20 so that arm 11 and the first pair of clamps 3, 4 cannot harm the operator. It may occur that an operator issues an order to activate the lifting means while the second pair of clamps 5, 6 is busy serving another loading post. In this case, the lifting means can interrupt slide 12 in the transfer position, with pivoting arm 11 in the initial position ( Fig. 3B ), long enough for the second pair of clamps 5, 6 to adopt the reception position, and then continue with the second rotation of pivoting arm 11 and transfer clothing article A to the second pair of clamps 5, 6 as described above in relation to Fig. 3C .
  • the rotation driving means of pivoting arm 11 include a fluid dynamics actuator 20, such as a pneumatic cylinder with rod mounted in slide 12 and connected to pivoting arm 11.
  • a pneumatic rotary actuator with blades could be used for the same purpose.
  • the translation driving means of slide 12 includes a linear fluid dynamic actuator 21, such as a pneumatic cylinder without rod, which also performs the function of rectilinear guide rails 13.
  • rectilinear guide rails 13 could be independent and cooperate with another type of linear fluid dynamic actuator with an equivalent result.
  • the translation driving means of slide 12, including rectilinear guide rails 13, is connected to regulating means adapted to move the whole translation driving means ensemble of slide 12 up and down, and with it loading post 2, in order to place the first pair of clamps 3, 4 of loading post 2 at a floor height that is adapted to the height of the operator.
  • Said regulating means includes, in the exemplary embodiment shown, a linear fluid dynamic actuator 27, without rod, to which pneumatic cylinder 21 without rod is connected, the latter forming the translation driving means of slide 12.
  • a drive command from said actuator 27 allows the user to conveniently regulate the height of the work post.
  • Each loading post 2 includes, in a place that the operator can easily access, controls 25 (not shown in Figs. 3A-3D ) including, as well as said height regulating control, a control for activating the driving means for running the loading cycle.
  • This action control is driven by the operator when he has finished manually loading an article of clothing on clamps 3, 4 in his particular loading post 2.
  • the action control includes a photocell that is activated simply by the operator passing his hand above or in front of it, which saves time and reduces operator fatigue.
  • the electronic control establishes an order of precedence for consecutively activating the driving means in each case, according to programmed maximum efficiency parameters.
  • the electronic control means controls the driving means so that the various first pairs of clamps 3, 4 corresponding to the various loading posts 2 alternate in transferring the corresponding flat articles of clothing to said second pair of clamps 5, 6 (or second pairs of clamps 5, 6, when there are more than one) depending on the order of precedence in which the operators have given the action orders via their respective action controls and finally depending on the maximum efficiency parameters programmed in the control means.
  • the apparatus includes a suction device 50 having a suction mouth 51 adjacent to a lower part of reception end 31 of conveyor belt 30 in order to attrach the flat article of clothing by means of a suction jet towards said reception end 31 of conveyor belt 30 and towards a longitudinal roller 52 located next to a lower edge of said suction mouth 51.
  • Said longitudinal roller 52 is driven to rotate at a relatively high speed so as to quickly introduce the hanging part of the article of clothing into box 53 of the suction device. This way, as conveyor belt 30 pulls the top part of the article of clothing, the part contained in box 53 is dragged outwards and towards the belt while mobile brushes 28 moving longitudinally in divergent directions next to suction mouth 51 remove any possible wrinkles from the article of clothing.
  • Figs. 1 and 2 show the apparatus of the invention in a loading mode suitable for loading flat, large size articles of clothing using the lifting means associated with loading posts 2.
  • another characteristic of the apparatus of this invention is that it includes a system whereby conveyor belt 30 can be collapsed so that reception end 31 thereof drops to a suitable height for at least one operator to directly and manually load flat, small size articles of clothing.
  • Fig. 4 schematically shows the same apparatus of Figs. 1 and 2 in said loading mode suitable for manual loading.
  • conveyor belt 30 is mounted on a chassis 26 that is mounted so that it can pivot around an axis in relation to frame 1
  • suction device 50 is mounted in a box 53 that is mounted so that it can pivot around another axis, separate from the pivoting axis of conveyor belt 30, in relation to frame 1.
  • a linking means is included between chassis 26 of conveyor belt 30 and box 53 of suction device 50 for releasably linking a pivoting movement of chassis 26 of conveyor belt 30 to a pivoting movement of box 53 of suction device 50 maintaining a relative, suitable position between reception end 31 and suction mouth 51.
  • Said linking means can, for example, be made up of connecting rods 29.
  • a driving means 22, such as, for example, fluid dynamic cylinders is adapted to pivot conveyor belt 30.
  • said linking means When said linking means is activated, the pivoting action of the conveyor belt causes suction device 50 to perform a corresponding pivoting action in order to alternate between the automatic loading mode ( Fig. 2 ), wherein reception end 31 is at a suitable height for loading flat, large size articles of clothing using lifting and spreading out means, and the manual loading mode ( Fig. 4 ) wherein reception end 31 is at a suitable height for at least one operator to directly load flat, small size articles of clothing.
  • Said pivoting axis of chassis 26 lies at a rear end thereof, near a delivery end 32 of conveyor belt 30.
  • Fluid dynamics cylinders 22 connect the front end of chassis 26 to frame 1, whereby an extension or withdrawal of fluid dynamic cylinders 22 causes chassis 26 to tilt with the whole ensemble of conveyor belt 30 so that delivery end 32 remains substantially in the same place.
  • loading posts 2 and the spreading out means 5, 6, 7, 8 are mounted on a mobile support structure 14 slidably mounted with respect to said frame 1 and associated with movement means, for example, an electric motor or fluid dynamic cylinders, enabling loading posts 2 and spreading out 5, 6, 7, 8 to move backwards beyond reception end 31 of conveyor belt 30, and above same, when reception end 31 is collapsed.
  • the apparatus includes retracting means allowing loading posts 2 to be retracted upwards, in the direction of rectilinear guide rails 13, until a lower end of the loading posts is arranged above reception end 31 of conveyor belt 30, when said end is collapsed in the manual loading mode, in order to provide enough space for an operator to be able to comfortably position, arrange and see a flat article of clothing on conveyor belt 30.
  • Said retracting means can be provided by the same linear fluid dynamic actuator 27, without rod, which activates the above-mentioned height regulating means of the first pair of clamps 3, 4 with respect to the floor, or by a specific actuator.
  • the apparatus includes an exit conveyor belt 40 having a reception end 41 arranged to receive flat articles of clothing from delivery end 32 of conveyor belt 30 and a delivery end adapted to load flat, conveniently spread out articles of clothing into a laundry processing unit, such as an ironing or folding machine serially connected to the apparatus.
  • delivery end 32 remains in the same position when conveyor belt 30 is collapsed, which facilitates the permanent link with reception end 41 of exit conveyor belt 40.
  • Said mobile support structure 14 is mounted on a top chassis 15 articulated with respect to a structural element 16 of frame 1.
  • Said top chassis 15 can be collapsed so that mobile support structure 14 drops downwards and loading posts 2 withdraw inwards, as shown in Fig. 5 , which reduces the overall volume of the apparatus. Since the rotation driving of top chassis 15 is only performed occassionally, dedicated driving means have not been provided, but instead the same fluid dynamic cylinders 22 used to drive chassis 26 of conveyor belt 30 are used, by temporarily using connecting rods or bars (not shown) between chassis 26 and top chassis 15.
  • exit conveyor belt 40 is also installed in a rear chassis 43 that is mounted so that it can pivot around an axis in relation to frame 1. Said pivoting axis of rear chassis 43 of exit conveyor belt 40 is near to said reception end 41, whereby reception end 41 does not substantially vary its position when exit conveyor belt 40 is pivoted. Pivoting driving means 23 make it possible to move rear chassis 43 of exit conveyor belt 40 between an operating position, extending outwards, and a folded position, backing on to the rear part of frame 1, which folded position, as well as providing access to a laundry processing unit connected on-line to the apparatus exit, reduces the overall volume of the apparatus.
  • a collapsed position of said top chassis 15 of frame 1 together with a folded position of exit conveyor belt 40, and additionally dismantling some cowling elements 19, 24, provides an apparatus volume that is suitable for being packaged in a box 17 of degradable or reuseable material, such as wood, said box 17 being adapted to be placed into a standard container 18, as shown in Fig. 5 .
  • the conveyor belt optionally includes two parallel conveyor belts, or more commonly two units of parallel conveyor belts associated with independent driving means or at least provided with independent transmissions.
  • the control means is adapted to activate together the driving of both belts or belt units to transport flat, large size articles of clothing to a central position, or to independently activate the driving of one or another belt or belt unit to transport flat, medium or small size articles of clothing on each of said belts or belt units.
  • a pair of second clamps 5, 6 is adapted to serve two of said loading posts 2 located at the right of the appparatus and the other pair of second clamps 5, 6 is adapted to serve the other two loading posts 2 located at the left of the apparatus.
  • a detection means is arranged to detect the size of the article of clothing held by each of the second pairs of clamps 5, 6 and the control means is adapted to activate the drive mechanism of the belts or belt units of conveyor belt 30, as a whole or independently, depending on the result of said detection.
  • the apparatus includes one or more connected control boxes for issuing orders to a laundry processing unit connected on line to the apparatus exit.
  • Said control box or boxes are arranged in chassis 26 of conveyor belt 30, near reception end 31, in a position or positions suitable for not interferring with any action or mechanisms when conveyor belt 30 is in said automatic loading mode, and for remaining comfortably at the disposition of the operator or operators when conveyor belt 30 is in said manual loading mode.
  • an operator can, for example, give different types of folding orders to a folding machine connected on line to the apparatus exit depending on the type of article of clothing spread out on conveyor belt 30, or that the article is not folded when an abnormal situation is detected, such as for example a stain.
  • the apparatus according to this invention described above allows a new method to be implemented for loading flat articles of clothing into a laundry processing unit, such as an ironing or folding machine.
  • the method includes, as is usual, the steps of manually catching the ends of a flat article of clothing in a first pair of clamps 3, 4 arranged in at least one loading post 2 controlled by an operator; moving said first pair of clamps 3, 4 to a higher position using lifting means associated with said loading post 2; transferring the flat article of clothing to a second pair of clamps 5, 6 associated with spreading out means including at least one pair of carriages 7, 8 running on respective guide rails 9, 10 transversal to the transport direction of said conveyor belt 30; spreading out the flat article of clothing by independently moving the pair of carriages 7, 8 carrying the second pair of clamps 5, 6, separating them from one another, between positions in front of loading post 2, of which there is at least one, and suitable positions with respect to the centre of conveyor belt 30; and placing one end of the flat, spread out article of clothing on said receptionend 31 of conveyor belt 30 with the help of blowing
  • the method of this invention is characterised in that the said step of moving the first pair of clamps 3, 4 to a higher position using said lifting means includes moving the first pair of clamps 3, 4 in a combined translation and rotation trajectory by means of at least one rotation, driven by rotation driving means, of at least one pivoting arm 11 supporting at one end the first pair of clamps 3, 4; and at least one translation movement, driven by translation driving means, of a slide 12 slidably mounted on rectilinear guide rails 13 and to which pivoting arm 11 is connected at its other end.
