## Background
TECHNICAL FIELD
The present invention relates to equipment for feeding laundry articles onto a conveyor system from which they are fed into subsequent processing machinery such as ironing machines, dryer, folding machines or the like.
The auxiliary device of this invention is intended to be installed in a machine for spreading out and loading flat clothing articles to a laundry processing unit, the machine including two or more loading stations served by respective operators for spreading and loading large flat clothing articles, such as sheets or tablecloths, in a semiautomatic loading mode, and alternatively allows spreading and loading small flat clothing articles, such as napkins, pillowcases, cloths or tablecloths in a manual loading mode.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 472,918 discloses a laundry feeding machine including a conveyor moving through a suction induction tunnel. Articles are held at their upper edges by an automatically releasing clamp to hang in front of the induction tunnel. Upon release of the clamp, a valving system is immediately actuated to apply suction to suck the article in to lie flat on the conveyor to be transported thereby. FIGS. 10 and 11 show an embodiment particularly adapted to the handling of very wide articles such as bed sheets including a transverse suction chamber that is evacuated by a blower at either end. The conveyor belts pass immediately over the top of the suction chamber. A nip roller 92 is positioned close to the end of the tunnel 94 to provide an adequate air seal to insure that the flow of air from the tunnel inlet 96 is confined to flow into the suction chamber.
U.S. Pat. No. 5,172,502 describes a feeding aid for assisting in the feeding of laundry flatwork to laundry processing equipment such as an ironer.
EP-A1-2584087 discloses a machine for spreading out and loading flat clothing articles onto a conveyor belt 30. The machine comprises a separator element 9 in the shape of a plate located above the conveyor belt 30 and the suction chamber. This separator element is moved by driving means in coordination with the movements of a protective cover 11 (associated to spreading clamps) between a separating position (FIG. 9) corresponding with the free passage position of the protective cover 11, and a refracted position (FIG. 10) corresponding with the retaining position of the protective cover 11. In the mentioned separating position (FIG. 9), a separating edge 9a of said separator element 9 is at a distance from the protective cover 11, which is located in its free passage position. This distance is sufficient to allow the passage of a first, second and third flat clothing articles A1, A2, A3 (A1 in FIG. 9) held and moved by the first or second spreading clamps 4a, 4b; 5a, 5b between their receiving and spread out positions but insufficient to allow the access of the hands of an operator to dangerous areas of the machine where the spreading clamps move at high speed.
However the embodiments of the prior art still are deficient in the transfer of the flat clothing articles as linen from the spreading clamps when being blow pushed onto the conveyor, mainly at the loading end or entrance of the conveyor and in the transition area. The following problems have been detected:

    
    
        loads due to undulation parts of the flat clothing while released by the clamps should be relieved
        the fall of the article should be better mastered;
        efficiently flat positioning of the article on the conveyor loading end is needed;
        a suitable cutch up of the corners is required;
        avoid interference between the pieces of clothing transferred and the newly arrived;
        reduce the friction of the clothing.
    
    


The present invention addresses all these problems and provides a suitable solution thereof.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
FIGS. 1a to 6 show an auxiliary device for a machine for spreading out and loading flat clothing articles according to this invention.
The machine comprises a conveyor belt 30 having a considerably horizontal or slightly inclined upper section moving in a loading direction D, and several pairs of clamps 20 installed on corresponding carriages which are independently moved by driving means along a guide rail, transverse to said loading direction D, between a receiving position, in which said first spreading clamps 20 are adjacent to one another in a loading station, and in which it receives contiguous corners of flat clothing articles A loaded manually by operators, and a spread out position, in which the spreading clamps 20 are separated from one another and positioned facing the loading end of the conveyor belt 30, spreading the flat clothing article A.
The auxiliary device of this invention helps in the transfer of said flat clothing article A from said position facing the loading end, and held by the spreading clamps 20, to an extended position with upper part of the flat clothing article A placed on the conveyor belt loading end 30a. 
According to a preferred embodiment illustrated on FIG. 1a to 7, the auxiliary device comprises a roof plate 13 located over the loading end 30a, and extended and articulated around a pivot axis 14 transverse to the loading direction D. Said pivot axis 14 allows said roof plate 13 to tilt between a first position (FIGS. 1a, 2 and 3), in which the roof plate 13 and its front end 13a are separated from the conveyor belt 30 leading end 30a, defining a wide opening for reception of the flat clothing articles A, and a second position (FIGS. 4, 5, 6 and 7), in which the roof plate 13 and its front end 13a are close to the conveyor belt 30 loading end 30a, allowing a passage of the flat clothing article A extended on said conveyor belt 30.
The roof plate 13 includes a spoil 16 attached at a rear part of it, being said spoil 16 able to tilt around the pivot axis 14 between a first position (FIGS. 4, 5, 6 and 7), in which the spoil 16 and its front end 16a are separated from the conveyor belt 30, defining a wide opening, and a second position (FIGS. 1a, 2 and 3), in which the spoil 16 and its front end 16a are close to the conveyor belt 30, allowing a passage of the flat clothing article A on said conveyor belt 30.
The roof plate 13 and the spoil 16 tilt around the pivot axis 14 at the same time because its attachment, and are configured to be on opposite positions, so when the roof plate 13 is on the first position, the spoil 16 is on the second position, and vice versa.
The pivot axis 14 rotation is activated by driving means, as for example: an electric motor, a hydraulic piston, a servomotor, a lineal motor, an electromagnetic pusher, etc.
The roof plate 13, the pivot axis 14, the driving means, and the spoil 16 are linked to guides 17, along which all of them can slide. Said guides 17 are not parallel regarding the conveyor belt 30 upper said, so sliding said devices on said guides 17, the distance between the pivot axis 14 and the conveyor belt 30 is increased, and the auxiliary device is disabled allowing for a manual loading operation mode (shown on FIG. 1b). This retired position of the roof plate 13 is the thereafter called third position.
The sliding movement along said guides 17 is achieved, on the preferred embodiment illustrated on FIG. 1a to FIG. 7, by a driving means 18 illustrated as a piston, but any other driving mean is contemplated, as a lineal motor, a threaded shaft, or any other well known in the state of art. The manual operation of said sliding movement is also contemplated.
In the illustrated example on FIG. 1a to 6, deposition means include blowing nozzles 12 fixed to the protective cover 11 and arranged to blow an airflow on an upper part of the flat clothing article A comprised between the loading end 30a and the pair of spreading clamps 20,
An additional blowing nozzle 15 is attached to the roof plate 13 placed on the lower side thereof, in an area close to the front end 13a, and directed against the conveyor belt 30 in the loading direction D, so that the airflow blown by said additional blowing nozzle 15, produces a further extension of the flat clothing article A loading edge, preventing undesirable folds of the flat clothing article A while in the transition movement to be placed against the conveyor end 30a. 
In order to prevent the fall of the flat clothing article A, after the release of the spreading clamps 20, and before its extension on the conveyor belt 30, two different embodiments are illustrated. On FIG. 1a to 6, a first embodiment is illustrated, in which a rotating roll 19 is placed confronted to the conveyor belt 30 front end 30a, existing a wide gap between them. When the flat clothing article A is gripped on the spreading clamps 20, said flat clothing article A is partially supported on said rotating roll 19, lying on it. By the rotation of the rotating roll 19, the flat clothing article A pending portion is partially lifted and introduced on said wide gap, so the majority of the flat clothing article A weight is supported on the rotating roll 19, and the loading end 30a only supports the weight of the flat clothing article A portion introduced on said wide gap.
On FIGS. 2 to 7 a suction box 21 placed under the loading end 30a of the conveyor belt 30 is detailed, so that the flat clothing article A gripped by the spreading clamps 20 is pending in front of said suction box 21, and the suction produced supports partially the weight of the pending flat clothing article A. The same suction box 21 also helps the rotating roll 19 to introduce the flat clothing article A inside the wide gap.
Thereafter the flat clothing article A transfer process from the spreading clamps 20 to the conveyor belt 30, using the auxiliary device is described.
In a first step illustrated on FIG. 2, the spreading clamps 20 have spread out a flat clothing article A in front of the loading end 30a, being the roof plate 13 on the second position RP2, and being the spoil in the first position SP1.
In a second step illustrated on FIG. 3, the spreading clamps 20 release the flat clothing article A corners, and the airflow produced by the blow nozzle 12 and the additional blow nozzle 15 attached to roof plate 13 introduces and extends a portion of said flat clothing article A on the conveyor belt 30 loading end 30a. 
The rotating roll 19 introduces a portion of the flat clothing article A inside the wide gap, and the blow nozzle 12 produces an airflow which pushes the flat clothing article A upper segment against the loading end 30a. 
FIG. 4 is a third step showing the transition of the flat clothing article A towards the conveyor belt loading end 30a pushed by both nozzles 12 and 15.
In FIG. 5, the fourth step is illustrated, in which the roof plate 13 is rotated towards RP1 position regarding the pivot axis 14, by said driving means, and the front end 13a of said roof plate 13 is placed slightly above the conveyor belt 30, so that the additional blow nozzle 15 blows close to the flat clothing article A, ensuring its proper extension.
In a fifth step, illustrated in FIG. 6, when the flat clothing article A is mostly loaded on the conveyor belt 30, the flat clothing article A lower edge has exceeded the rotating roll 19, and is pending in the wide gap, the roof plate 13 stays on the first position, and a cover 13b is extended covering the wide gap, so that an additional flat clothing article A gripped on the spreading clamps 20, can be placed confronted to the loading end 30a of the conveyor belt 30 before the complete load operation of the preceding flat clothing article A, because the additional flat clothing article A cannot interfere with the flat clothing article A which is being loaded on the conveyor belt, thanks said cover extension, on which the additional flat clothing article A lies during said fifth step.
The extension and retraction of said cover 13b can be achieved by a driving means, as a motor, a piston, a lineal motor, a magnetic pusher, etc.
The fifth step is followed by the first step so that the operation cycle is restarted.
It should be noted that during the second step (FIG. 3), in which the roof plate 13 is placed on the first position RP1, the previous flat clothing article A is still being transferred on the conveyor belt 30, and the spoil 16 is placed on the second position SP2, ensuring that the lower edge of the previously loaded flat clothing article A has been perfectly extended on the conveyor belt, and preventing the lifting and bending of said lower edge due the airflow blown from the nozzles 12 and the additional blowing nozzles 15. The spoil shape is designed to deflect in the second position SP2 said airflow away from said lower edge.
In an alternative embodiment spoil 16 can be driven by own driving means.
In FIG. 7 a second embodiment is illustrated without rotating roll 19. In this case another suction box 40 is foreseen to attack lower section of the flat clothing article A close to the loading end 30a, partially supporting the weight of said flat clothing article previous to its transfer onto the conveyor belt 30.
