Definitions
- the present invention relates to a semi-automatic device for continuously locating by an operator the X and Y coordinates of singular points within a surface such as for example a sheet, a film or fabric or a plate. rigid in motion, or their image on a screen.
- singular points is meant in particular local defects, especially within a fabric, such as for example defects in material, knitting or weaving or even color defects.
- the term “singular points” also denotes knots or other irregularities which may appear on a plate, in particular of wood, or even a local insert. In other words, we define by “singular points” any visible element which distinguishes itself in a uniform set.
- this device delivers a label on which are written the fabric code and the number of defects as well as their distribution according to the length.
- this device does not allow the location of faults to be listed exactly.
- the exact distribution of defects within a piece of fabric that is to say an overall estimate of the quality of the fabric, has an impact on the rationalization of its use.
- the cutting made within a piece of fabric is a function of the two-dimensional distribution of the defects within said piece.
- the present invention aims to overcome these drawbacks.
- its main goal is to allow location according to two coordinates, that is to say according to the coordinates of the plane observed.
- It relates more particularly to a device allowing the identification of faults on a piece of fabric and which, moreover, also allows the real localization of said faults after constitution of a mattress from this fabric to carry out manufacturing operations.
- the solution described in this document generally consists of scrolling the material to be inspected (tissue) on a control plane and of detecting faults by means of a system using a light source which is captured. by a receiving element arranged on the other side of the face of the textile. Consequently, depending on the amount of light transmitted, it is therefore possible, starting from an average level, to detect either an excessive transmission corresponding to a lighter hole or zone in the tissue, or, conversely, a transmission insufficient corresponding to more opaque areas.
- the invention proposes a device making it possible to locate the two coordinates of one of the singular points likely to appear on a surface and to record them in order to deliver an accurate statement of the two-dimensional distribution of said singular points.
- the following description relates to a device for locating local faults within a fabric or a fabric.
- the invention cannot be limited to this embodiment, and that any surface having singular points as defined in the preamble of this description, can be analyzed by a device of the same type, conforming to the invention, with a few structural adjustments.
- the locating device basically comprises a reading plane (1), slightly inclined, having an opening closed by a frosted glass (2). Behind this frosted glass is located a light source emitting through said frosted glass.
- Said inclined plane (1) comprises along two of its opposite edges two rollers (3,4) intended to allow the movement of the piece of fabric (10) controlled. These rollers (3) and (4) are conventionally driven by a motor, not shown;
- an input rule (5) is fixed (a rule consisting for example of 192 indicator lights located every centimeter), located transversely to the direction of travel of the piece of fabric to be checked.
- This seizure rule also comprises slides, not shown, allowing the attachment and adjustment in position of width sensors (8) and (9) serving as elements for controlling the width of the fabric.
- width sensors (8) and (9) serving as elements for controlling the width of the fabric.
- width sensors means the width of the piece of fabric.
- these sensors consist of a plurality of photoelectric cells having an average center distance of the order of five millimeters. The variations in width are recorded within the central unit (11) and, conventionally, only the minimum width, the maximum as well as the average width of said piece of fabric finally emerge.
- the gripping rule (5) further comprises at its forehead, that is to say at the level of the meeting of the piece of fabric which passes with said rule, a ramp of photodiodes (15), the lighting is controlled by a manipulator (12) located at a central input and recording unit (11), the latter being electrically connected to the input rule (5).
- a measuring wheel (6) intended to measure the length of the movement of the piece of fabric (10), is fixed by means of a support (7) to the grip rule (5).
- This metering wheel allows in particular to measure the length of each piece of fabric.
- the central input and recording unit (11) comprises a keyboard (13) making it possible to record the code or the reference of the controlled piece of fabric. It also includes a display (14) for viewing the reference of the piece of fabric as well as the code listing the identified fault. The selection of one or other of the indices of the code likely to be displayed on the member (14) is performed by the manipulator (12) by actuating it on one of its two degrees of freedom.
- the central recording and recording unit (11) comprises a printer which delivers, after checking each piece of fabric, a label intended to be affixed to said piece of fabric (10), said label. comprising in addition to the reference of said piece of fabric, the extremes and the average of the width of said pieces, the type of defect identified and for each of the faults their X and Y coordinates.
- the piece of fabric (10) to be controlled being in place on the control plane (1), its advancement is controlled by means of a pedal (not shown) actuated by the operator.
- a pedal not shown
- the control of the movement of the piece of fabric (10) can be ensured at the level of the manipulator (12) by simple rotation of said manipulator. In this case, the latter would then have three degrees of freedom.
- the operator When the operator sees a defect of any kind, it causes the positioning (displacement) of the visible mark constituted in the embodiment described by the illumination of one of the photodiodes constituting the ramp (15), and matches said visible reference with the observed defect.
- the defect When the defect is located directly above the photodiode, namely on the one hand the vertical alignment along the Y coordinate, that is to say along the transverse axis with respect to the direction of travel of the piece of fabric (10), but also plumb with the photodiode considered on the X coordinate, the operator presses the end of the manipulator (12), causing the immediate entry of the X, Y coordinates of the identified fault. This entry must then be stored in the central entry and recording unit (11).
- the operator actuates the manipulator (12) according to another degree of freedom in order to select the category of the identified fault.
- the operator also enters it by simply pressing the end of the manipulator (12).
- the category of the fault identified is then also recorded in the central data entry and recording unit.
- the operator then continues to check the pieces of fabric (10) by again scrolling said piece.
- the identification of faults within the piece of fabric is effected by a simple back-and-forth movement of the visible mark in this case constituted by photodiodes, thus transforming an activity particularly tedious in an almost fun activity.
- the exact two-dimensional determination of the distribution of defects within a part of fabric but also within any surface, or its image on a screen allows an optimization of their use where a significant saving.
- the device according to the invention is applied to locating singular points of any type of flat surface, and in particular in the textile industry in locating local faults.
- Such a fault identification system can, as illustrated by FIG. 2, be used to allow the actual location of said faults after constitution of a mattress.
