Definitions
- Visual inspection device for objects made of flexible, flexible flat material, especially textiles.
- the invention relates to a visual inspection device for objects made of soft, flexible flat material, in particular textiles, clothing, laundry and the like, according to the preamble of patent claim 1. Laundry or textile inspection machines.
- a "dimmer" control is provided with which the operator can set the desired brightness.
- Such a laundry testing device consists of fluorescent tubes arranged in a housing, which are covered by a glass pane. This device has the disadvantage that it has a strong glare effect on the operating personnel, so that it is frequently switched off, which also affects the life of the fluorescent tubes.
- the object of the invention is to provide a test device of the type mentioned at the outset which is distinguished by ease of use, in particular by avoiding intense light nuisance or even glare to the operating personnel, with a simple and reliable construction.
- the achievement of this object is determined by the features of patent claim 1. Further developments of the invention are determined by the features of the subclaims.
- Fig.l a first embodiment of an inventive
- Test device in the form of a laundry tester with a rectangular, elongated test object holder in a perspective view
- FIG. 2 shows a vertical section of the device oriented in the longitudinal direction of the test object according to FIG. 1,
- FIG. 4 shows a second embodiment of a laundry testing device according to the invention in side view with a vertical partial section of the test object
- FIG. 5 shows a schematic block diagram of the control device of the device according to FIG. 4.
- the laundry tester 10 shown in FIG. 1, designated overall by 10, has a cuboid housing 12, in which fluorescent tubes 14 are arranged.
- the housing 12 is covered on its top with a glass pane 16, the other walls are made of opaque material.
- the glass pane 16 is designed as a frosted glass pane in order to reduce glare as much as possible.
- the light tubes are arranged in pairs next to one another in right and left groups 30, 32, which can be switched on and off separately. This means that a wider or narrower field can be used for laundry testing.
- the fluorescent tubes 14 can be set to a lighter and a darker value, the darker value being set in such a way that it does not dazzle the operating personnel but does not permit a laundry test.
- the lighter value is set so that it enables a laundry check but would blind the operating personnel.
- This brightness value, the test value is used for the laundry test.
- Proximity switches 24 are arranged on the front and rear sides of the glass pane 16, the feed side 20 and the discharge side 22, wherein each of the respective front or rear proximity switches can also consist of groups of switches. If the fluorescent tubes 14 are divided into groups 30, 32, a proximity switch can be provided on the feed side 20 and on the discharge side 22 for each group. The proximity switches are switched in such a way that when the proximity switches are covered with a piece of laundry, the brightness of the fluorescent tubes 14 on both the feed side 20 and the discharge side 22 is regulated to the larger of the set values, while only one of the proximity switches is uncovered the brightness is adjusted to the smaller value. It is thereby achieved that the greater brightness is set only when the glass pane is completely covered with a piece of laundry to be tested, whereby glare to the operating personnel is completely avoided.
- Fig. 3 shows the control and operating elements of the device.
- a mains connection 26 supplies the device with electrical energy, and it is switched on and off via a main switch 28.
- Groups 30 and 32 are switched via switches 34 and 36, light and dark control via a respective dark control regulator 38 and a hot control regulator 40.
- the brightness control of the fluorescent tubes allows them to be adjusted to the individually desired strength by the respective operating personnel, namely to a lighter test value and a darker standing value.
- the lighter test value is used to check a piece of laundry placed on the glass pane, while the darker stand value turns on when no piece of laundry is placed on the laundry tester.
- the test value and standing value can be fixed, but they can also be regulated separately from one another in order to enable the operating personnel to set the brightness values individually.
- proximity switches are arranged which generate a switching pulse when an object approaches. Switches which react to movement serve, for example, as such proximity switches.
- proximity switches for example, reflection light scanners can be used, which are preferably equipped with background suppression and thus respond to a narrow test area. B. on a test area of 10 to 20 mm.
- the proximity switches are switched in such a way that when the two proximity switches are covered, they set the brightness to the brighter test value, while when only one or none of the proximity switches is covered, the brightness is switched to the darker standard value. It is thereby achieved that only when the entire glass pane, which serves as a test field, is covered by a piece of laundry, is switched to the brighter test value, which enables the item of laundry to be checked. If the glass pane is only partially or not at all covered by a piece of laundry so that both proximity switches do not react, the brightness of the fluorescent tubes is reduced to the standard value, so that there is no blinding for the operating personnel.
- the glass pane can be designed as a frosted glass pane, which further reduces the glare for the operating personnel.
- the fluorescent tubes especially in the case of wide laundry testing devices, which are required for the testing of larger items of laundry, can be divided into two or more groups lying next to one another, which can be switched on and off separately, so that one group is switched off when smaller items of laundry are put on can and therefore no lateral glare can be caused.
- the housing of the laundry testing device can be laterally displaceable on guides, so that it can be moved laterally beyond the edge of the table on which it is attached or beyond its support so far that bags and the like can be seen from the side the test field can be drawn in order to enable the checking of laundry bags, covers and the like.
- the glass pane 16 forms a
- Object recording the upper side of which is designed as a test object support surface AF.
- the proximity switches 24 act as presence detectors for a test object 0 indicated in FIG. 2, here a piece of laundry.
- test objects are introduced into the working space R above the support surface and spread out on the support surface so that glare can no longer occur. This is monitored by the detectors mentioned, which - together with the associated control elements, which are not shown here - are a monitoring device UVa.
- the fluorescent tubes form an overall lighting device LV, which are in optical operative connection with the underside of the object holder. This itself has a visually diffusing effect and thus enables a flat view of the object.
- the proximity switches form an object detector device, with a group of adjacent proximity switches or proximity detectors of another, usually conventional type, being assigned to a part TF of the test object support surface AF and thus to a light unit 30 or 32 formed by two light tubes 24 is.
- These detector groups deliver an object presence signal assigned to the degree of coverage of the assigned part TF of the test object support surface AF by test object material.
- These signals are combined in a logic circuit which is customary per se and therefore not to be described in more detail to form a lighting control signal in such a way that a predetermined operating value, in particular a maximum value, of the lighting is activated on all detectors only when an object is present.
- the device can also be designed with technical advantages in such a way that the lighting device has a plurality of lighting units which can each be controlled individually - here, for example 30 and 32 -, each of which is assigned to a proximity detector or a group of proximity detectors logically conjunctively combined on the output side.
- the associated lighting unit is activated in accordance with a predetermined operating value, in particular a maximum value, of the lighting only when there is an object on the detector or group of detectors in question.
- a monitoring device UVb is provided with a brightness detector device HDV, which detects at least a part of the working space R or the test object support surface AF.
- the monitoring device further comprises a limit value / actual value comparison device GIV which is operatively connected to the output of the brightness detector device HDV, the output of which is in control connection with the lighting device LV
- the test object recording PA has a translucent, optically diffusing test object support surface AF, the brightness detector device HDV having a plurality of brightness detectors HD, which are assigned to a part TF of the test object support surface AF in a conventional manner. Each of these detectors is assigned to a part TF of the test object support surface AF by alignment and / or blanking. By arranging an appropriate number of detectors, the area resolution of the monitoring can be increased without great effort.
- the lighting device LV comprises a plurality of lighting units LE, each of which can be controlled individually, each of which is assigned to a brightness detector HD or a group of brightness detectors.
- the output of each brightness detector assigned to a lighting unit or the superimposed or averaged outputs of a group of such brightness detectors is connected to a limit value comparator GV of the limit value / actual value comparison device GIV.
- the limit value comparators GV and the associated lighting units are in a control connection which limits their intensity to a predeterminable maximum value.
- the test work can be continued without interruption, but with the exclusion of the surface area which is thus hidden. However, this is easily recognizable within the contact area and can be quickly re-included in the test by moving the test object.
- a separate, adjustable limit transmitter GG is expediently provided for each brightness detector HD and thus for each assigned partial area TF within the limit value / actual value comparison device GIV on the relevant limit value comparator GV.
- the subject of a special development of the invention is to use the control means already given to identify the dimmed lighting unit and thus the associated area by activating a spatially assigned optical signal transmitter of a conventional type.
