    Description [0001] The present invention relates to a modular apparatus for the automatic determination of characteristics of elongated textile samples such as yarns, threads, ribbons and the like.
    [0002] The quality control of a yarn is of fundamental importance to check both the production processes and the subsequent processing processes.
    [0003] In general, the quality control of a yarn consists in determining different structural and / or physical-mechanical characteristics. More specifically, the yarn is subjected to various tests designed to verify its structural characteristics, such as for example the linear mass (titer), the number of twists, the hairiness, the linear regularity, ie the constancy of the structural characteristics along its development longitudinal, and the physical-mechanical characteristics, such as for example the dynamometric characteristics of the type of elongation at break by traction, of the tensile strength (ie the maximum tensile strength), of the elastic tensile modulus and the relative tension curve /deformation.
    [0004] Automatic or semi-automatic devices are known for determining individual structural or physical-mechanical characteristics of the yarns.
    [0005] For example, automatic or semi-automatic devices are known for determining the linear mass (the so-called "titrators" or hairiness (the so-called "pelosimeters") or the linear regularity (the so-called "regularity") or dynamometric characteristics (the so-called "dynamometers").
    [0006] The complete characterization of the yarns requires the determination of a plurality of such characteristics; it is therefore necessary to have a corresponding plurality of such devices on each of which the tests must be individually performed often with the assistance of an operator assigned to loading the individual yarns to be tested.
    [0007] The results of the various tests must also be collected, correlated and processed in order to obtain a complete definition of the individual yarns to be compared with reference standards.
    [0008] This operating mode requires the installation and management of various devices, is particularly laborious, complex and long and often requires the intervention or assistance of an operator.
    [0009] Multifunctional automatic or semiautomatic apparatuses are also known, that is, they perform multiple tests, even simultaneously, on the same sample of yarn or even on samples of yarns which are different from each other.
    [0010] Examples of such automatic or semi-automatic equipment are described in US 8 079 255, US 5 842 373 or in US 4 843 879. US 4 843 879 describes an apparatus provided with two measuring stations: a first station, in correspondence with of which there is a device for determining the titer and a device for determining the linear regularity of a yarn sample under test, and a second station, at which there is a device for determining the torsion and / or of the dynamometric characteristics of a sample of yarn under test. The two measuring stations can operate subsequently or simultaneously on the same yarn sample or on different yarn samples.
    [0011] The apparatus is fed at the entrance by a plurality of packages (bobbins, bobbins, spindles, etc.) supported by a creel; a pneumatic system recalls the yarns of each package entering the equipment.
    [0012] The ends of the yarns entering the apparatus are arranged manually between respective gripping members, which are arranged along an arc of circumference and together form a loader device.
    [0013] A manipulator arm with three degrees of freedom and provided with a head provided with a gripper member and a cutting member is arranged to take the yarn inlet ends from the loading device and distribute them in the two measuring stations.
    [0014] Each of the two measuring stations is governed by a respective microprocessor so as to be able to operate independently of one another; these microprocessors are connected to a central control and command unit and data processing unit detected during each test.
    [0015] A suction device withdraws and evacuates the tested textile samples.
    [0016] Although this apparatus has proved to be particularly advantageous, it has certain disadvantages inherent, in particular, in the device for loading and handling textile samples.
    [0017] The inlet ends of the textile samples are taken from the respective gripping members by the manipulator and from there inserted in one of the test devices following a path which is at most defined by transmission rollers having fixed positions; each textile sample then follows a different path along which it is subjected to uncontrollable tensile and / or friction forces which influence the individual tests as well as being able to damage or in any way alter the individual sample under test.
    [0018] The cutting of the textile samples already tested is then performed by the manipulator and the stretch of the tested textile sample is evacuated by a common suction device. This, on the one hand, slows down the operation of the equipment and, on the other hand, makes the correct removal of the tested textile sample which could get tangled in the various components of the equipment problematic. Automatic or semi-automatic devices are also known for measuring dynamometric characteristics marketed by the company USTER Technologies AG such as "Uster® Tensorapid 4", which are equipped with a loading device consisting of a plurality of grippers of the free end of a respective textile sample fed by a corresponding package (cone, reel, spindle, etc.) supported by a creel. These gripping members are supported in succession to one another by a motorized chain or belt which arranges them individually and successively at a fixed inlet device comprising guide and return rollers, a cutting assembly and a group of aspiration.
    [0019] A manipulator arm takes the end of the textile sample to be tested from the respective gripping members, which have been previously aligned with the input device, and inserts it into the actual dynamometer making it pass through the input device.
    [0020] In this case, the tests are performed on one textile sample at a time. Tests on different textile samples are carried out in the same order and in the same sequence in which the textile samples are inserted in the gripping devices of the loader device; these gripping members, in fact, are individually arranged, one after the other, at the inlet device.
    [0021] Furthermore, a loader device of this kind is not suitable for being applied to equipment capable of simultaneously performing two or more tests on two different samples.
    [0022] The object of the present invention is to overcome the drawbacks of the prior art.
    [0023] Within the scope of this general purpose, a particular object of the present invention is to provide a modular apparatus for the automatic determination of characteristics of elongated textile samples of the type of yarns, threads, ribbons and the like, which allows to feed and manipulate the individual textile samples to be tested so as to be able to check possible pre-loads due to the friction or traction forces exerted on them and thus obtain more precise and accurate measurements.
    [0024] Another object of the present invention is to provide a modular apparatus for the automatic determination of characteristics of elongated textile samples of the type of yarns, threads, ribbons and the like, which allows to manage in a versatile manner the loading and the feeding of the single textile samples to be tested and allowing two or more textile samples to be loaded and fed simultaneously, avoiding friction and pre-loading.
    [0025] Yet another object of the present invention is to provide a modular apparatus for the automatic determination of characteristics of elongated textile samples of the type of yarns, threads, ribbons and the like, which allows to perform in an integrated manner two or more measurements of structural and / or physical-mechanical characteristics of textile samples subsequently or simultaneously on the same sample or on different samples.
    [0026] Yet another object of the present invention is to provide a modular and modular apparatus for the automatic determination of characteristics of elongated textile samples of the type of yarns, threads, ribbons and the like, simple, functional and of low cost.
    [0027] These and other objects are still achieved by a modular apparatus for the automatic determination of characteristics of elongated textile samples such as yarns, threads, ribbons and the like, as defined in claim 1.
    [0028] Further characteristics are defined in the dependent claims.
    [0029] The characteristics and advantages of a modular apparatus for the automatic determination of characteristics of elongated textile samples of the type of yarns, threads, ribbons and the like according to the present invention will become more evident from the following description, given as an example and not for limiting purposes, referring to schematic drawings attached in which: fig. 1 is a front elevation view of a modular automatic apparatus for the automatic determination of characteristics of textile samples; fig. 2 and 3 are axonometric views, respectively from the front side and from the rear side, of the loading module of the apparatus of fig. 1; fig. 4 is an axonometric view of a carriage of the loading module of fig. 1; fig. 5 is an axonometric view of a detail of the trolley of fig. 4; fig. 6 is a front view of fig. 5; fig. 7 and 8 are sections respectively according to planes VII-VII and VIII-V of fig. 6; fig. 9 shows a partial cutaway view of the gripping members of the loading module of the apparatus in fig. 1.
    [0030] With particular reference to the accompanying figures, 100 indicates as a whole a modular apparatus for automatically determining characteristics of elongated textile samples of the type of yarns, threads, ribbons and the like.
    [0031] In the following description reference will be made to the apparatus 100 considered in its usual use configuration in which it is resting on the ground and reference will be made to a Cartesian XYZ system as indicated in figure 1 in which the XY plane indicates the floor support on the ground or horizontal plane.
    [0032] The apparatus 100 comprises a housing 101 to which are associated: - a loading module 102 of the ends of a plurality of textile samples to be tested / characterized, each of which is wrapped in a corresponding supply package of the type of a coil, a bobbin, a spindle or the like, supported by a creel or other equivalent support to be associated to the apparatus 100 and not shown, - at least one measurement module 103, 104 of at least one structural or physical-mechanical characteristic of a textile sample, - manipulator means (i.e. manipulator) 105 for manipulating the textile samples between the loading module 102 and the at least one measuring module 103, 104, - a central unit of programmable type (not shown) for management and control of the loading module 102, of the at least one measuring module 103, 104 and of the manipulating means 105 and for processing the measurements made by the at least u n measurement module 103, 104.
    [0033] Advantageously, the apparatus 100 comprises: - at least a first measuring module 103 for measuring at least a first structural characteristic of the textile samples, and - at least a second measuring module 104 for measuring at least one second physical characteristic -mechanical of textile samples, in which the at least one measuring module 103 and the at least one second measuring module 104 are able to operate subsequently or simultaneously on a same textile sample or on two different textile samples.
    The apparatus 100 may further comprise at least one third measurement module 106 for the measurement of a further structural feature of the textile samples and / or a fourth measurement module 107 for measuring a characteristic of textile samples of the type of manually inserted wicks in it. The various measurement modules 103, 104, 106 and 107 can also operate simultaneously and in parallel on the same or different samples.
    [0035] The first measurement module 103 is able to measure at least one structural characteristic of the textile samples chosen between the regularity of the linear mass (i.e. the regularity of the titer) and the hairiness, advantageously both. The first measuring module 103, therefore, comprises a hairiness measuring device 130 and a device for measuring the regularity (regularity of the linear mass) 131 which are arranged one above the other and substantially aligned with each other or in any case aligned. along a sliding path P of the textile sample and driving means 132 aligned or in any case aligned with the path P and which are arranged below the hairiness measuring device 130 and of the regularity measuring device 131 and which are configured to slide the textile sample along the route P.
    [0036] The second measurement module 104 is able to measure at least one physical-mechanical characteristic of the textile samples and, in particular, a dynamometric characteristic of the type of elongation at break by traction, of the tensile strength (ie the maximum load of tensile failure) and the related tension / deformation curve and, in the embodiment shown in fig. 1, it is constituted by a measuring device 140 of the type of a dynamometer which, advantageously, is of the type object of a simultaneous patent application in the name of the same owner and which is referred to here in its entirety.
    [0037] In general terms, the measuring device 140 comprises a pair of clamps 141, 142 arranged vertically one above the other and of which the one at the lower level 142 is movable in translation towards and away from the upper one 141. Each terminal 141, 142 comprises a fixed jaw and a movable jaw in translation along a horizontal direction (axis Y) with respect to the fixed jaw to clamp and release a corresponding portion of a textile sample. The upper clamp 141 is coupled to means for detecting the force to detect the traction force applied to the textile sample under test, while the relative displacement between the two clamps 141, 142 is detected directly or indirectly by transducer means.
    [0038] The third measurement module 106 is adapted to measure a physical characteristic of the type of linear mass (title) of the textile samples. The third measuring module 106 is therefore constituted by a so-called "titrator".
    [0039] The first measuring module 103, the second measuring module 104 and the possible third and fourth measuring modules 106 and 107 are not described in detail being of a type known to the person skilled in the art, except for the characteristics of the shape of realization of the second measurement module 104 object of the aforementioned simultaneous patent application in the name of the same owner.
    [0040] In completely general terms, the first measuring module 103 comprises a hairiness measuring device 130 as for example described in the patent application IT 1 413 638 and a regularity measuring device 131 of the type for example capacitive. In order to align the inlet opening of the hairiness measuring device 130 with that of the regularity measuring device 131, the first is supported by a movable slide with a command along a horizontal direction orthogonal to the path P.
    [0041] The driving means 132 comprise a pair of rotatable rollers in opposite directions and at controlled speeds and between which the textile sample under test is dragged. Also the driving means 132 are supported by a movable slide with a command along a horizontal direction orthogonal to the path P to align with the inlet opening of the hairiness measuring device 130 and with that of the regularity measuring device 131.
    [0042] The third measuring module 106 comprises, in general terms, its own driving means 161 of the textile sample similar to the driving means 132, cutting means 162 of a section of the textile sample whose length is indirectly determined by motion measurements of the driving means 161, braking means (i.e. means for applying to the textile sample a determinable and controllable friction force) 163 of the textile sample, suction means 164 of the section of cut sample and weighing means housed inside the housing 101 and not shown in the attached figures.
    [0043] The fourth measurement module 107 is of the type of a capacitive regulator of a known type.
    [0044] The third measuring module 106 and the first measuring module 103 are aligned one above the other in a first measurement zone M1.
    [0045] The second measurement module 104 is arranged in a second measurement zone M2 distinct from the first measurement zone M1. The possible fourth measurement module 107 is arranged in a third measurement zone M3 different from the first and second measurement zones M1 and M2 and not reached by the manipulator means 105.
    [0046] The manipulator means 105 are movable between the loading module 102, the first measurement zone M1 and the second measurement zone M2; they are designed to perform movements of translation and / or rotation around the three XYZ axes.
    [0047] In the embodiment shown in the accompanying figures, the manipulator means 105 comprise a quadrilateral articulated structure movable in the vertical plane (i.e. the ZY plane as indicated in Fig. 1) and which has a cylindrical joint 150 coupled to non-actuating means visible and the cylindrical joint 151 opposite it provided with a manipulation head 152 able to rotate around the axis X and provided with pincer means for gripping and releasing the textile samples (the manipulation head 152 is however without cutting means of the yarn). Advantageously, the gripper means of the manipulation head 152 are configured to apply a pressure proportional to the tensile strength of the textile samples under test, tensile strength which is estimated on the basis of the title of the textile samples themselves. This prevents the individual textile samples being tested from being damaged or broken.
    [0048] Advantageously, moreover, the arms which form the articulated quadrilateral of the manipulator means 105 are made of carbon fiber. This makes it possible to contain the overall weight of the manipulator means 105 and, therefore, limit its inertia which causes positioning inaccuracies of the relative manipulation head 152. Furthermore, the realization of these carbon fiber arms gives the manipulator means 105 high dimensional stability, to the advantage of a high precision of positioning of the relative manipulation head 152. The manipulator means 105 are not further described since they are of a type immediately understandable to the person skilled in the art.
    [0049] According to an aspect of the present invention, the loading module 102 comprises a plurality of gripping members 200 for locking the inlet ends of a corresponding plurality of textile samples to be tested, each of which is wrapped in a corresponding packaging of the type of a bobbin, a bobbin, a spindle or the like and supported by a creel not shown.
    [0050] The gripping members 200 are aligned along an advantageously vertical loading direction DC (i.e. parallel to the axis Z) and are individually movable between a locking position and an unlocking position of the inlet end of a respective textile sample .
    [0051] Furthermore, the loading module 102 comprises one or more, advantageously two, carriages 201, each of which is individually movable in translation in both directions along a direction parallel to the loading direction DC so as to be able to align in such a way selective to one of the grip members 200.
    [0052] Each carriage 201 is provided with at least one operating group selected from the group comprising: a cutting assembly, a brake assembly, a guide-transmission assembly and an aspiration assembly of a textile sample; such at least one operating unit is arranged at the side of the gripping members 200 facing the measuring modules 103, 104, 106.
    [0053] Each carriage 201 is further provided with at least one auxiliary operating group selected from the group comprising: a guide-transmission unit and a brake assembly; this at least one auxiliary operating unit is arranged at the side of the gripping members 200 opposite to that facing the measuring modules 103, 104 and 106.
    [0054] Each carriage 201 is then coupled to its own motor means 202 which activate its translation movement; the central unit is adapted to control and control the motor means 202 for controlling and controlling the movement of the respective trolley 201 so as to place it selectively in correspondence with one of the gripping members 200.
    [0055] In greater detail and with particular reference to the embodiment shown in the accompanying figures, each carriage 201 comprises a base body 203 which is guided, by means of a rectilinear guide 204, in translation in both directions along a direction parallel to the DC loading direction.
    [0056] The base body 203 is associated with the respective motor means 202 by means of means for converting the rotary motion of the first into translational motion of the second of the type, for example, with pinion 205 and rack 206, being immediately understandable for the a person skilled in the art who the motor means 202 and / or the means for converting and transmitting the motion can have different and completely equivalent embodiments.
    [0057] The base body 203 supports at least one first support body 207 which is arranged at the side of the gripping members 200 facing the measuring modules 103, 104, 106 and which supports at least one operating group selected among a group cutting unit, a brake assembly, a suction unit and a group for returning a textile sample.
    [0058] The first support body 207 is supported by the base body 203 in a way movable in a direction orthogonal to the sliding plane of the trolley 201 (i.e. along the axis X); a first linear actuator 208 is also supported by the base body 203 to actuate the motion of the first support body 207 approaching or moving away from the sliding plane of the carriage 201 (plane ZY) so as to be able to align the supported operating groups from the first support body 207 to the height, with respect to the ZY plane, of the textile sample to be picked up and removed from the respective gripping members so as to avoid sliding friction of the first on the latter, frictions which would alter and damage the textile sample, for example, increasing hairiness or reducing mechanical strength.
    [0059] The first support body 207 supports in succession starting from the inlet end (i.e. the end facing the gripping members) towards the outlet end (i.e. the end facing the measurement modules) along a sliding path P1 of the input textile sample: a first guide-transmission assembly 209, a cutting unit 210, a brake assembly 211, an intake assembly 212 and a second guide-transmission group 213.
    [0060] The first guide-transmission unit 209 comprises a grooved-type wheel or roller 214 which is rotatably supported by means of a shaft from the first support body 207; the roller 214 is arranged with its own axis of rotation parallel to the loading direction DC.
    [0061] The cutting unit 210 comprises a blade 216 and a check plate 217 the one relatively mobile in approaching and moving away from the other by means of a respective linear actuator 218 of the type with double pneumatic cylinder-piston effect.
    [0062] The brake assembly 211 comprises a pair of yarn braking discs 219, 220 of which one is relatively mobile in approaching and away from each other by means of a respective linear actuator 221 of the pneumatic piston-cylinder type double-acting.
    [0063] The suction unit 212 comprises a suction mouth 222 which is connected to a venturimeter suction device not shown being of a known type.
    [0064] The second guiding-guide assembly 213 comprises a pair of wheels 223 and 224 which are rotatably mounted about a respective axis orthogonal to the plane ZY; along an arc of circumference of each of the two wheels 223 and 224 facing the measurement modules an invitation profile 225 and 226 of the textile sample is arranged towards the measurement modules.
    [0065] The fittings 215 with a pneumatic circuit are also provided on the first support body 207.
    [0066] Advantageously, the base body 203 of each trolley 201 also supports a second support body 227 which is arranged at the side of the grip members 200 facing the feed (creel) of the textile samples and which supports at least one auxiliary operating group selected between a brake assembly and a guide-transmission unit of the textile sample.
    [0067] In the embodiment shown, the second support body 227 is coupled to the base body 203 in a way movable in a direction orthogonal to the sliding plane of the trolley 201 (i.e. axis X); a second linear actuator 228 is also supported by the base body 203 to actuate the motion of the second support body 227 approaching or away from the sliding plane of the carriage 201 (plane ZY) so as to be able to modify the share of the groups auxiliary operating elements supported by the second support body 226 with respect to the level with respect to the ZY plane of the textile sample to be picked up and removed from the respective sample members so as to avoid sliding friction of the first on the latter, frictions which would alter and damage the sample textile, for example increasing its hairiness or reducing its mechanical resistance. The second support body 227 supports a brake and / or guide-transmission assembly consisting of a wheel 229, advantageously of the grooved type, rotatable about a vertical axis (axis Z, parallel to the sliding direction DC); by changing the height of the wheel 229 with respect to the sliding plane of the carriage 201, the entry trajectory of the textile sample is modified and the sliding resistance exerted thereon.
    [0068] Each carriage 201 also comprises actuator means 230 for the actuation of the grip members 200 between their locking position and their unlocking position.
    [0069] Each gripping member 200, in fact, comprises a pair of grippers 231a, 231b aligned with one another along a coplanar direction and orthogonal to the loading direction DC for taking two corresponding portions of the inlet end of a respective textile sample.
    [0070] Each pincer 231 a, 231 b comprises a first element 232 fixed with respect to the housing 201 and a second element 233 which is coupled to the first element 232 in a movable manner in contrast to elastic means 234 between an approached position, for gripping and the locking between them of the respective portion of the inlet end of the respective textile sample, and a position moved away, for release and release, of the respective portion of the inlet end of the respective textile sample.
    [0071] In the embodiment shown in the accompanying figures, the first element 232 is constituted by a hollow pin and the second element 233 is constituted by a stem inserted in a movable manner in the first element 232 and provided at one end with a head 235 which rests on a corresponding end of the hollow pin and at the opposite end of an abutment 236 of the elastic means 234.
    [0072] The textile sample is clamped between the head 235 and the hollow pin.
    [0073] The actuator means 230 comprise a pair of pneumatically actuated push rods able to act on the second elements 233 of each pair of pincers 231 a, 231 b in contrast to the elastic means 234 to force them into their release and release position.
    [0074] The measurement modules, the loading module and the manipulator means are equipped with their own microprocessor connected to the central unit, this makes the equipment 100 modular and modular according to different needs.
    [0075] For the person skilled in the art, the operation of the apparatus 100 is immediately understandable from the above description and from the attached figures.
    [0076] An operator manually arranges the input ends of the samples to be tested between the pairs of pincers 231 a, 231 b of the gripping members 200.
    [0077] The central unit, as set and programmed, controls and controls the various components of the equipment 100 for the execution of one or more tests on the loaded textile samples.
    [0078] Depending on which textile sample is to be tested, one of the two carriages 201 is positioned next to the respective pair of pincers 231a, 231b which holds its respective inlet end. The first support body 207 and the second support body 227 are arranged at the desired height with respect to the sliding plane of the respective trolley 201. The manipulator means 105 are arranged with the gripping head at the inlet end of the textile sample from picking up and picking it up as soon as it is released from the respective pair of grippers 231a, 231 which are in turn pushed into their release and release position by the actuator means 230 supported by the trolley 201.
    [0079] The manipulation means 105 arrange the end of the textile sample thus withdrawn at the input of the operating groups supported by the first support body 207 of the trolley 201, dragging it along the path P1 and subsequently inserting it in the measuring module 103, 104 or 106 pre-set, which then executes the respective test one or more times as planned.
    [0080] During the execution of the test, the textile sample is kept in a position detached from the respective pair of grippers, is guided and supported by the first guide-transmission unit 209 and by the second guide-transmission group 213 and possibly braked by the group brake 212 of the respective carriage 201.
    [0081] While a textile sample is tested by one of the measurement modules 103, 104 and 106, another textile sample can be simultaneously tested in another of the measurement modules 103,104 and 106. The measurements can thus also be carried out in parallel on modules of different measurement. Similarly, it is possible to conduct a test on a wick by means of the fourth measurement module 107 simultaneously and parallel to the tests performed on one or two textile samples by means of one of the measurement modules 103, 104 and 106.
    [0082] At the end of the tests, the textile sample is, where necessary, cut by the cutting unit 210 of the respective trolley 201.11 suction unit 212 together with the suction units which are locally provided in correspondence with the individual measuring modules remove the sections of the textile sample thus cut or in any case separated, without the need for the manipulator means 105.
    [0083] It should be noted that the carriages 201 can be arranged in a selective manner next to any of the gripping members 200 and that the two carriages 201 are independent of each other.
    [0084] The apparatus is completed with 100 safety barriers such as photocells.
    [0085] The apparatus of the present invention has the advantage of allowing the removal of one or more textile samples and their supply to the measuring modules of which it is equipped in a simple, rapid and flexible manner.
