    The invention relates to a device for inspecting laundry items according to the preamble of claim 1. Furthermore, the invention relates to a device for folding laundry items according to the preamble of claim 10 and a method for inspecting laundry items according to the preamble of claim 14.
    It is common in commercial laundries in particular to inspect laundry items for errors or to control. This is especially true for so-called flat linen such as tablecloths, sheets, duvet covers or the like.
    It is known to inspect laundry items before folding. The laundry is then already washed and mangled. Thereafter, any stains remaining in the laundry and even holes or other defects can be visually recognized. So far, the inspection of laundry items is done manually on so-called control tables on which operators hang up the laundry item manually spread. For better recognition of errors, the inspection of the laundry items is often on illuminated tables, so that the laundry items to be inspected are durchleuchtbar. The manual inspection of the laundry is also very labor intensive when it is done on illuminated tables.
    The invention has for its object to provide a method and a device for inspecting laundry items and such a device having device for folding laundry items, whereby the manual effort for inspecting or controlling the laundry items can be reduced.
    A device for achieving this object has the features of claim 1. In this device, it is provided to raise and spread the laundry item on a surface inspection by a spreader beam with two movable brackets. The operator thus needs only to hook opposite corners of a leading edge of the laundry in the brackets of the spreader bar. All other activities, in particular the strenuous spreading and mounting of the item of laundry on the inspection surface, are done by the machine according to the invention.
    The spreader beam is preferably designed so that the two brackets after the manual hooking the corners of the laundry are synchronously moved apart in opposite directions for spreading or stretching a held between the brackets held by the corners located leading edge of the laundry article. The operator can easily enter the corners of the garment when the staples are moved together because they do not need to stretch the leading edge of the garment. The hooking of the corners of the laundry item into the clamps that have moved together can be carried out ergonomically and without tiring.
    Preferably, the spreader beam is movable over opposite longitudinal edges of the inspection surface. The opposite longitudinal edges of the inspection surface thereby form guides for driving over the spreading surface extending transversely to the direction of the drawing of the item of laundry over the inspection surface. For this purpose, rails, in particular guide rails, can be assigned to the opposite longitudinal edges of the inspection surface, on which rollers or carriages can be moved at opposite ends of the expansion beam.
    A preferred development of the device, it provides that a rear or upper transverse edge of the inspection surface is assigned a turning conveyor. With the turning conveyor, the laundry item can be transported away from the inspection surface after inspection or inspection in the extended state. Preferably, the turning conveyor is designed so that it passes the laundry at a rear or upper end of the inspection surface, turns it and after turning the laundry in the spread state under the inspection surface along transported back into the region of the front and bottom transverse edge of the inspection surface where the corners of the garment have been manually hung in the collapsed brackets of the spreader beam prior to inspection. From here, the spread laundry may be supplied to a subsequent laundry treatment device, in particular a folding device such as a folding machine. This can be done without significant modification of the folding device, because the respective inspected laundry item is transported back in the spread state back to the starting position by the turning conveyor, where it was manually entered into the device for inspecting the laundry item (inspection device).
    The turning conveyor is formed in a preferred embodiment of the invention as a sandwich conveyor. The sandwich conveyor has two belt conveyors with partially spaced runs. Between these contiguous runs, between the belt conveyors forming the sandwich conveyor, the inspected laundry is carried away from the inspection surface by turning and returning below the inspection surface.
    According to a preferred embodiment of the turning conveyor additionally has a feed belt conveyor, which forms an inlet gap at the rear, upper end of the inspection surface. The inspected item of laundry is drawn through the inlet gap in the turning conveyor and transported back by this below the inspection surface or inspection plate. In the intake gap, the front edge of the spread laundry article with an adjoining edge region of the brackets of Spreizbalkens is hineintransportierbar. It is done by the brackets, a transfer of the front edge region of the spread inspected garment to the turning conveyor.
    Preferably, the two conveyor belt forming the sandwich conveyor over the width of the inspection surface. The belt conveyors can therefore take over the spread on the inspection surface garment in the extended state and convey back to a starting position at the front or lower transverse edge of the inspection surface. By contrast, the intake belt conveyor is narrower, so that it comprises only a central region of the spread laundry article. In this way, the serving for the delivery of the spread laundry article to the turning conveyor clamps pass on opposite edges of the narrower Einzugsgurtförderers and thereby enter the leading edge of the laundry in still stretched or expanded state in the intake nip, in particular insert.
    A serving for solving the task device for folding laundry items (folding device) has the features of claim 10. Accordingly, the folding device is associated with a device referred to below as an inspection device for inspecting laundry items. The inspection device can be an additional device, with which a conventional folding device can be retrofitted. The items of laundry can thus be visually inspected or checked on the folding device. Thereafter, the laundry items can be treated individually depending on the result of the check. In particular, during the check, laundry items which have been found to be in order are then folded by the folding device in the usual way, ie conventionally.
    Preferably, the inspection device over the folding device, in particular over the folding of the same, arranged. In this case, the inspection device is preferably pivotable about a particular horizontal axis of rotation. As a result, the inspection device can be swung down to save space when not in use. By pivoting up into a position of use, the inspection surface is pivoted in front of the field of view of the at least one person taking control. As a result, the person can visually inspect or inspect a piece of laundry which has been spread completely on the inspection surface in unattended posture.
    In a particularly advantageous embodiment of the invention, the pivot axis, to which the inspection device is pivotable relative to the folding device, a lower or front transverse edge of the inspection device, in particular the inspection surface assigned. This makes it possible for the person performing the inspection to bring the inspection surface into the desired ergonomically favorable position by corresponding pivoting of the inspection device about the lower pivot axis.
    The assignment of the inspection device to the folding machine is preferably made such that an output end of a turning conveyor transfers the laundry item to a feed conveyor of the folding device. In particular, the laundry item from the discharge end of the turning conveyor of the inspection device can be placed on the feed conveyor of the folding device, in the extended or extended state in which the turning conveyor takes over the inspected laundry item from the inspection surface. In this way, the folding device need not have any modifications for the inspection device. Rather, the inspection device is designed so that it passes the spread laundry article after inspection to a conventional folding device, just as happens in a folding device without an upstream inspection device in which the laundry is also laid out spread by an operator on the feed conveyor.
    The folding device associated with the inspection device is preferably formed according to one or more of the directed on the inspection device (device for inspecting laundry) claims 1 to 8 or further developed.
    A method for inspecting laundry items to solve the problem has the measures of claim 14. In this method, it is provided that a front edge of the laundry item is stretched by two brackets of a Spreizbalkens and raised by the spreader on the inspection surface. This method makes it possible to automatically apply the laundry in the spread or spread state on the inspection surface. A laborious manual spreading and placing the laundry on the inspection surface is unnecessary.
    Preferably, it is provided that during the inspection or inspection of the laundry opposite corners of the front edge of the laundry remain held by the brackets. The laundry item is thus stretched on the one hand reliably and spread out fixed on the inspection surface. On the other hand, the laundry item can be pulled down by the clamps after the inspection of the inspection area or transferred to a subsequent conveyor, such as a turning conveyor.
    A preferred embodiment of the method provides it, to transport back from the turning conveyor the spread laundry under the inspection surface in the region of a lower or front transverse edge of the inspection surface. The controlled piece of laundry passes so behind and / or below the inspection area along near the starting position in which the laundry item has been hung with opposite corners of the leading edge manually in the brackets of Spreizbalkens. From here, the laundry may be transferred in a conventional manner to a feed conveyor of a folding device.
    A preferred embodiment of the invention will be explained in more detail with reference to the drawing. In this show:<Tb> FIG. 1 <SEP> is a schematic side view of a device for folding items of laundry with one of these associated device for inspecting laundry items in a raised operating position of the device,<Tb> FIG. 2 <SEP> a side view of the device for inspecting laundry items,<Tb> FIG. 3 <SEP> an enlarged detail III of the device for inspecting laundry according to the Fig. 2, and<Tb> FIG. 4 is a plan view of an inspection surface of the laundry inspection device.
    In Fig. 1 is a device for folding laundry items 10, namely a folding device 11, with a fixedly arranged means for inspecting the laundry items 10, namely an inspection device 12, is shown. The laundry items 10 are preferably flat items such as tablecloths, napkins, sheets, duvet covers, pillowcases, or the like.
    The folding device 11 is preferably such a conventional type. There are thus no constructive adjustments of the folding device 11 to the associated inspection device 12 is required. The folding device 11 has at the beginning of a feed conveyor 13, which each transported a single spread laundry article 10 to a folding section of the folding device 11, not shown in detail. The folding path is used for at least one time transverse folding and / or longitudinal folding of the laundry 10. This is done by conventional, the folding line associated folding blades, folding conveyor or folding flaps. At the end of the folding path, the folding device 11 has at least one dispensing means, for example a stacking device 14. In addition, the folding device 11 is provided for the removal of laundry items 10, which have turned out to be faulty in the inspection, for example, have holes or stains.
    The inspection device 12 is arranged with vertical support arms 15 fixed above the folding device 11. This arrangement is such that the inspection device 12 about a horizontal pivot axis 16 relative to the folding device 11 by at least one, preferably two, pressure medium cylinder 17 is pivotable. The pressure medium cylinders 17 may be pneumatic cylinders. The pivot axis is arranged in the vicinity of the lower or front, horizontal transverse edge 18 of the inspection device 12, above the feed conveyor 13 in front of the folding device 11. In the raised position shown in FIG. 1, the inspection device 12 is ready for operation. In an unillustrated, downwardly pivoted rest position, the inspection device 12 is flat, preferably approximately horizontally, above the folding device 11. The inspection device 12 releases the feed conveyor 13 at the beginning of the folding device 11 for the manual direct storage of laundry items 10 on the feed conveyor 13.
    The inspection device 12 has a rectangular inspection surface 19, which corresponds in size to the largest to be folded, spread laundry 10. This ensures that every item of laundry 10 to be folded can fit on the inspection surface 19 in the extended state. In the case of the inspection device 12 shown here, the inspection surface 19 is designed to be translucent or translucent. Accordingly, the inspection surface 19 is located on a flat, box-like light table 20 of the inspection device 12. The light table 20 makes it possible to illuminate the inspection surface 19 at the back, so that the lying on the inspection surface 19 lying laundry 10 from the light table 20 is transilluminable.
    Above the inspection surface 19 of the inspection device 12, a movable elongated spreader beam 21 is arranged. The spreader beam 21 extends transversely over the inspection surface 19, that is parallel to the transverse edge 18 of the inspection surface 19. Opposite ends of the spreader beam 21 are movably mounted on parallel rails 22. The rails 22 are mounted on the parallel longitudinal edges 23 of the inspection surface 19 and the light table 20. Along the rails 22, the transverse spreading bar 21 is movable over the inspection surface 19, from front to back or from bottom to top, that is from the front transverse edge 18 of the inspection surface 19 to the rear (upper) transverse edge 24 of the inspection surface 19 and beyond ,
    The spreader bar 21 has two brackets 25 for forming a pair of clips. In the brackets 25 are manually opposite corner areas or corners of a front edge 26 of the laundry item 10 can be suspended. The brackets 25 are along the Spreizbalkens 21 in opposite directions together and moved apart. In the collapsed brackets 25, the two the leading edge 26 delimiting corners of the laundry item 10 are entered manually. By opposing moving apart of the brackets 25, the front edge 26 of the laundry item 10 is spread. By moving the Spreizbalkens 21 on the rails 22 to the rear, upper transverse edge 24 of the light table 20, the laundry item 10 is mounted in the extended state on the inspection surface 19 and held by the brackets 25 of the spreader 21.
    Viewed in the mounting direction of the laundry article 10 on the inspection surface 19, a turning conveyor 27 is disposed behind the inspection surface 19 and below the light table 20. The turning conveyor 27 has a sandwich conveyor comprising two endless belt conveyors 28 and 29 and an endless draw belt conveyor 30. The belt conveyors 28 and 29 and the draw belt conveyor 30 have a plurality of narrow endless conveyor belts 31, 32 and 33 adjacent to each other at close intervals. The number and the width the conveyor belts 31, 32 and 33 is selected so that the belt conveyors 28 and 29 extend over the entire width of the inspection surface 19, the Einzugsgurtförderer 30 but is narrower, namely extends only over a central portion of the inspection surface 19, preferably about half as wide as the inspection surface 19 is.
    Both belt conveyors 28 and 29 have a double opposing angled, so about Z-shaped course. For this purpose, the conveyor belts 31 of an upper belt conveyor 28 facing the light table 20 are guided by six deflection drums 34 to 39. One of these deflecting drums 34 to 39 is driven. A first deflecting drum 34 is located approximately at the level of the inspection surface 19 directly behind the upper or rear leading edge 26 of the inspection surface 19. From here, the conveyor belt 31 is seen in the direction of rotation 40 deflected by an approximately vertical underlying deflection drum 35 by 90 °. From here, the conveyor belt 31 extends below the light table 20 along the deflection drum 36. An underlying deflection drum 37 forms a feed conveyor 13 of the folding device 11 facing belt loop with approximately vertical or slightly oblique course of the conveyor belts 31. From the guide drum 37, the conveyor belts 31 again led to a tail pulley 38, from which the conveyor belts 31 are led back in parallel under the light table 20 to a tail pulley 39. From this, the conveyor belts 31 are again led up to the deflection drum 34 behind the transverse edge 24 of the inspection surface 19. The parallel between the idler pulleys 35 and 36 Under the light table 20 extending portion of the conveyor belts 31 forms a Untertrum 41 of the upper belt conveyor 28. Between the deflecting drums 34 and 35 a decking 42 of the belt conveyor 28 is formed.
    The forming together with the upper belt conveyor 28 the sandwich conveyor lower belt conveyor 29 also has a double angled course. The conveyor belts 32 of the belt conveyor 29 are guided around their own deflection drums 43 to 46 and the deflection drums 35 and 36 of the belt conveyor 28. Preferably, one of the deflection drums 43 to 46 is driven. The uppermost deflection drum 43 of the belt conveyor 29 is spaced from the upper deflection drum 34 of the belt conveyor 28, so that behind the inspection surface 19, an upwardly open V-shaped gap between the deflection drums 34 and 43 is formed. Of the tail pulley 43 of the conveyor belt 32 runs in the direction of rotation 47 seen to the tail pulley 35, to which also the conveyor belt 31 of the belt conveyor 28 is deflected. Together with the lower run 41 of the conveyor belt 31 of the belt conveyor 28, an upper run 48 of the belt conveyor 29 passes under the light table 20 along the guide drum 36, at which the conveyor belt 31 of the belt conveyor 28 is deflected. From here, the conveyor belt 32 of the belt conveyor 29 is deflected down to the deflection drum 44, which is spaced from the deflection drum 37 to form a downwardly open V-shaped gap. From the tail pulley 44, the conveyor belts 32 of the belt conveyor 29 are returned to the tail pulley 45 and the tail pulley 46 to the upper rear tail pulley 43.
    The narrow feed belt conveyor 30 is guided around a horizontal own tail pulley 49 and the deflection drums 35, 36, 44, 45, 46 and 43 for the lower belt conveyor 29 and the lower run 41 of the upper belt conveyor 28. A tail pulley of the intake belt conveyor is preferably also driven. The deflection drum 49 is arranged at a distance above the deflection drum 34 behind the rear transverse edge 24 of the inspection surface 19. This creates behind the transverse edge 24 of the inspection surface 29 a tapering with increasing distance to the transverse edge 24 inlet gap 50 for an inspected, spread laundry 10. The laundry 10 is passed from the inlet gap 50 to the tail pulley 34 approximately vertically downwards between the deck 42 of On the tail pulley 35 runs the upper run 48 of the conveyor belts 32 of the lower belt conveyor 29 against the conveyor belts 33 of the Einzugsgurtförderers 30. Between the deflection drums 35 and 36, the laundry item is 10th transported further under the light table 20, the laundry item 10 in the driven state between the lower run 41 of the upper belt conveyor 28, the conveyor belts 33 of the narrower Einzugsgurtförderers 30 and the opposite to the edges of the narrower Einzugsgurtförderers 30 on both sides above rtrum 48 of the lower belt conveyor 29 sandwiched sandwiched or covered on both sides. After passing through the deflection drums 36, the conveyor belts 31 of the belt conveyor 28 are moved apart by deflecting the guide drum 37 and the conveyor belts 32 and 33 of the lower belt conveyor 29 and the Einzugsgurtförderers 30 to the tail pulley 44 and thereby between the conveyor belts 31 on the one hand and the conveyor belts 32nd and 33 on the other hand to the tail pulley 36 trapped on both sides laundry 10 released so that it can reach on the under the idler pulleys 37 and 44 located feed conveyor 13 of the folding device 11.
    The belt conveyors 28, 29 and the Einzugsgurtförderer 30 are driven to turn the inspection area 19 leaving garment 10 equally fast, so that there is no delay in the sandwich between the deflection drums 34 and 35 and the idler pulleys 35 and 36 between the Conveyor belts 31, 32 and 33 spread trapped or trapped garment comes. It is conceivable to drive the belt conveyors 28, 29 and the intake belt conveyor 30 continuously, that is, continuously. It can also be provided to drive the belt conveyors 28 and 29 and the intake belt conveyor 30 only when an inspected laundry item 10 is to be supplied from the inspection surface 19 of the folding device 11.
    The method according to the invention will be described in more detail below with reference to the previously described folding device 11 and inspection device 12:
    Each one to be inspected or controlled and to be folded garment 10 is hooked by an operator with opposite corner regions of a leading edge 26 in the contracted brackets 25 of the Spreizbalkens 21. Thereafter, the laundry item 10 is mounted on the inspection surface 19 of the light table 20 after a start signal of the operator. For this purpose, the brackets 25 are moved apart in opposite directions until the front edge 26 of the laundry item 10 is spread or stretched and the spreader beam 21 raised with the brackets 25 on or on the rails 22 to the upper transverse edge 24 of the inspection surface 19. The method of Spreizbalkens 21st and the brackets 25 may be sequential, but also synchronous. When the spreader beam 21 is raised and the clamps 25 are moved apart, the laundry item 10 to be inspected is spread out on the inspection surface 19. The operator can swivel the inspection device 12 as far as desired, in such a way that they control the laundry item 10 on the inspection surface 19 in a position that is comfortable for them can.
    From the light table 20, the laid out lying on the inspection surface 19 laundry item 10 is illuminated while the operator of the control of the laundry item 10 for errors, such as holes or stains made. During inspection, the laundry item 10 continues to hang on the brackets 25 of the spreader bar 21. Due to the inspection device 12 pivoted up during the inspection, the spread laundry article 10 hangs down on the brackets 25 during control, whereby it also spreads in the longitudinal direction due to gravity . outstretched on the inspection surface 19 is located.
    If no error is found in the control of the laundry item 10, the laundry item 10 of the folding device 11 is supplied. For this purpose, first the spreading bar 21 is moved over the upper transverse edge 24 of the inspection surface 19 upwards. In this case, the opposite corners of the front edge 26 of the laundry 10 holding brackets 25 pass the opposite longitudinal edges of the narrower Einzugsgurtförderers 30. The brackets 25 overtake the beginning of the Einzugsgurtförderers 30 and the tail pulley 49. In addition, the brackets 25 move with the front edge 26 of the garment 10 here over the tail pulley 34 and the conveyor belts 31 of the upper, wider belt conveyor 28 along. In the method of the brackets 25 on opposite edges of the Einzugsgurtförderers 30 over there is the introduction of a subsequent to the leading edge 26 front portion of the laundry article 10 in the inlet gap 50 of the turning conveyor 27. The front portion of the laundry article 10 can now be sandwiched between the Decktrum 42 of Belt conveyor 28 and the cover strand 51 of the Einzugsgurtförderers 30 detected and transported in the direction of rotation 40 of the conveyor belts 31 and 33 first behind the light table 20 down and then parallel to the bottom of the light table 20 under the same along to the tail pulley 36. On the way between the idler pulleys 35 and 36 is the laundry 10 between the lower run 41 of the upper Gurtförderers 28 on the one hand and the conveyor belts 33 of the Einzugsgurtförderers 30 and on opposite sides of the conveyor belts 33 laterally projecting upper run 48 of the lower belt conveyor 29 on the other.
    From the tail pulley 36, the conveyor belts 31 of the belt conveyor 28 and the conveyor belts 32 and 33 of the belt conveyor 29 and the Einzugsgurtförderers 30 run in opposite directions, so that a vertically downwardly open, V-shaped widening gap arises. The garment 10 is released on both sides of the conveyor belts 31, 32 and 33, whereby it can hang down vertically. In this case, the laundry item 10 with the extended front edge 26 advances to the feed conveyor 13 of the folding device 11 located below the V-shaped gap. The transport speed of the feed conveyor 13 is preferably coupled to the speed of the belt conveyors 28 and 29 and the intake belt conveyor 30 or slightly larger, so that the laundry item 10 to the same extent, in which it leaves the outlet gap between the belt conveyors 28, 29 and the Einzugsgurtförderer 30, via the feed conveyor 13 of the folding path of the folding device 11 can be fed, preferably continuously.
    The turning conveyor 27 also causes the top of the stretched out on the inspection surface 19 laundry item 11 is reversed when deflecting the upper transverse edge 24 of the inspection surface 19, so that the top is directed at the back transport under the light table 20 down, when the laundry item 10 is conveyed back on the way from the deflection drum 35 to the deflection drum 36 between the conveyor belts 31, 32 and 33 under the light table 20 in the direction of the front transverse edge 18 of the inspection surface 19th
    In the foregoing, the procedure has been described in the context of a garment 10 found to be in order during the inspection. If, during the inspection of the item of laundry 10, it is ascertained that this item has at least one stain, it is transported to the folding apparatus 10 in exactly the same way as a defect-free item of laundry 10 in the manner described above. The laundry item 10 then passes through the folding device 11 despite the stain and is folded by the latter in the intended manner, namely according to a corresponding program. Only after folding the stained garment 10 is sorted out, preferably before it is stored on a stack of faultless folded garment 10. Alternatively, it is conceivable that a piece of laundry 10 having a stain is ejected even before folding, for example in the region of the feed conveyor 13, for example, by conveying it off a faulty piece of laundry 10 in another direction, so that the laundry item 10 having at least one stain does not get to the folding line.
    In the case of a laundry item 10 having at least one hole, the procedure is such that the respective hole or other defective location is marked in front of a post-processing to eliminate the error. This is done manually by the operator of the inspection device 12. For this purpose, the laundry article 10 is lowered by retracting the Spreizbalkens 21 in the direction of the lower transverse edge 18 of the inspection surface 11 as much as necessary. The brackets 25 remain apart, so that the laundry item 10 freely hangs down in the extended state before the inspection surface 10, at least partially. The laundry item 10 is lowered by the spreader bar 21 so far that the operator can easily mark the respective defective location. This can also be done so that always a part of the laundry article 10 remains on the inspection surface 19 and only an upper part of the laundry article 10 is lowered by shutting down the clamp beam 21 on a lower portion of the inspection surface 19, which is better accessible by the operator. The inspection surface 19 then forms a support for marking the damaged spot by the operator.
    After the faulty location, such as a hole is marked by the operator, the laundry item 10 is raised from the clamp bar 10 in the still spread state over the upper transverse edge 24 of the inspection surface 19 away, so that the laundry item 10 in the inlet gap 50 of the turning conveyor 27 passes and from this under the inspection device 12 along the feed conveyor 13 of the folding device 11 can be fed. Also, the marked error, such as holes, having laundry 10 is in the folding device 11 as usual, namely according to the proposed folding scheme or folding program, folded and then sorted out, before it is placed on the stack of faultless laundry items 10. Optionally, laundry items 10 with marked holes or other errors in the area of the feed conveyor 13 can be sorted out or removed.
