Description
Introduction to the invention 1. Field of the invention The present invention relates to a yarn monitoring device and a yarn winding machine. 2. Description of the prior art [0002] A yarn monitoring device, such as a yarn clearer, is arranged in the yarn winding machines to detect a state of a yarn, such as the thickness of a yarn. An example of such a yarn monitoring device is disclosed, for example, in the published Japanese patent application n. 2000-327 226. This yarn monitoring device comprises a light-emitting element, such as a light-emitting diode (LED), which emits a light on a moving yarn, and a light-receiving element, such as a photodiode (PD), which detects light reflected from the yarn and / or a light that has passed through the yarn.
[0003] At the same time, since in the monitoring device of a yarn as explained above the light-emitting element and the light-receiving element are arranged so as to be in front of the sliding region of the yarn, it is difficult mounting both the light emitting element and the light receiving element on the same control substrate. Therefore, electric cables are generally used to electrically connect the light-emitting element and / or the light-receiving element to the control substrate.
[0004] When the electric cables are used as above mentioned, however, it is necessary to weld the electric cables to the pins of the light-emitting element and / or of the light-receiving element and then cover the connecting parts between the feet and electrical cables with an insulating element such as a heat-shrink tube. This can lead to a reduction in the assemblability. Moreover, when it is necessary to bend the electric cables with strong angles due to space limitations, the connection parts between the feet and the electric cables are subjected to stress. This can lead to a reduction in durability.
Summary of the invention [0005] In view of the above, an object of the present invention consists in presenting a monitoring device for a yarn having improved assemblability and durability, and in presenting a yarn winding machine which includes such a device. yarn monitoring. This object is achieved with a yarn monitoring device according to claim 1.

The first electronic component and the second electronic component, when viewed from a direction of sliding of the yarn that runs in the sliding region, are arranged in different positions around the sliding region. The yarn monitoring device comprises a circuit substrate. The circuit substrate comprises a first mounting element, a second mounting element and a first wiring element. The terminals of the first electronic component are connected to the first mounting element. The terminals of the second electronic component are connected to the second mounting element. The first wiring element electrically connects the first mounting element to the second mounting element.
[0007] According to a preferred embodiment of the present invention, a monitoring device for a yarn which detects a state of a yarn which slides in a sliding region comprises a first electronic component arranged around the sliding region, a second component electronic arranged around the sliding region and a rigid-flexible substrate disposed around the sliding region. The first electronic component and the second electronic component are electrically connected to the rigid-flexible substrate. The state of the yarn is detected by a combined action of the first electronic component and the second electronic component.
[0008] According to a further aspect of the present invention, a machine for winding a yarn which forms a bobbin by winding a yarn comprises the aforementioned device for monitoring a yarn.

Detailed description of some of the embodiments of the present invention with reference to the attached drawings are described in detail below. The same reference numbers have been attributed to the same or similar structural components in the drawings and a double explanation of the same has been omitted.
First embodiment [0012] As shown in fig. 1, a spinning unit 1 forms a bobbin P by winding a yarn Y. In the spinning unit 1, a traction device 2, a spinning device 3, a yarn feeding device 4, a yarn splicing device 6, a yarn monitoring device 50 and a winding device 7 are arranged in this order from top to bottom along a sliding path of the yarn Y. The spinning unit 1 also comprises a controller 8 which controls the operation of the entire spinning unit 1. Several winding units 1 of this type are arranged next to each other to form a spinning machine (a yarn winding machine) 10. In this configuration, the junction device of the thread 6 is arranged in a movable way with respect to the various spinning units 1 and the junction device of the thread 6 performs the operation of joining the thread in the spinning unit 1 in which the thread occurred. interruption of yarn. It should be noted that it is possible to arrange a junction device of the thread 6 for each spinning unit 1. The interruption of the yarn can occur for various reasons, for example when the yarn Y breaks for some reason or when the yarn Y is cut for eliminate a yarn defect.
[0013] The traction device 2 comprises a pair of rear rollers 11, a pair of third rollers 12, a pair of intermediate rollers 14 around which a conveyor belt 13 and a pair of front rollers 15 are loaded. traction 2, a belt S contained in a belt for collecting the belt 16 is pulled and stretched using the pairs of rollers 11, 12, 14 and 15 to form a bundle of fibers F.
[0014] The spinning device 3 is an air spinning device which forms the yarn Y by applying a twist to the bundle of fibers F formed by the traction device 2 using a vortex flow of air. Specifically, the spinning device 3 comprises (although not specifically illustrated) a spinning chamber, a fiber guide section, a vortex flow generating air outlet and a hollow guide shaft element. The fiber guide section guides the fiber bundle F formed by the traction device 2 towards the inside of the spinning chamber. The vortex flow generation of air generates the swirling air flow inside the spinning chamber. Consequently the direction of the ends of the fibers guided towards the inside of the spinning chamber is reversed and also the ends of the fibers perform a whirling motion. The hollow guide shaft element guides the yarn Y from the spinning chamber towards the outside of the spinning device 3.
[0015] The yarn feeding device 4 comprises an exit roller 17 and a pressure roller 18. The yarn feeding device 4 advances the yarn Y formed by the spinning device 3 towards the winding device 7 compressing the yarn Y between the exit roller 17 and the pressure roller 18.
[0016] The yarn monitoring device 50 detects a state of the yarn Y in movement. As soon as it detects a yarn defect in the moving yarn Y, the yarn monitoring device 50 cuts the yarn Y with a cutter not shown included in the yarn monitoring device 50. Cutting of the yarn Y can be performed with interruption or similar of the vortex flow of air inside the spinning device 3 instead of using the cutter.
[0017] The junction device of the thread 6 comprises a suction tube 21, a suction mouth 22 and a splicer 23. The suction tube 21 is rotatably supported and grips one end of the thread of the yarn Y from the device of spinning 3 and guides the end of the thread gripped towards the splicer 23. The suction mouth 22 is also rotatably supported and grasps one end of the thread of the yarn Y from the winding device 7 and guides the end of the thread gripped towards the splicer 23. Splicer 23 joins the ends of the wire guided towards it from the suction pipe 21 and the suction mouth 22.
[0018] The joint 23 constitutes a junction section of the thread which uses a vortex flow of air. The splicer 23 comprises a twisting section 23a which, in the case of cutting of the yarn Y, removes the end of the thread of the yarn Y coming from the spinning device 3 and the end of the thread of the yarn Y coming from the winding device 7, and a twist section 23b which twists the non-twisted ends of the wire using the swirling air flow. As an alternative to the air splicer 23 it is possible to use a disc splicer or a knotter.
[0019] The winding device 7 forms the bobbin P by winding the yarn Y. The winding device 7 comprises a housing arm 24, a winding cylinder 25 and a translating device 26. Supporting the bobbin P rotatably, the housing arm 24 causes the surface of the bobbin P to contact the surface of the winding cylinder 25 with an appropriate pressure. Consequently, when the winding cylinder 25 rotates, also the bobbin P which is in contact with the winding cylinder 25 rotates due to the action of the housing arm 24. The translating device 26 translates the yarn Y over a predetermined width on the bobbin P, which wheel thanks to the winding cylinder 25. The shape of the cone P is not restricted to a cylindrical shape, and the cone P can have other shapes, including a conical shape. Between the spinning device 3 and the winding device 7 there is arranged an accumulation section of the yarn which accumulates the yarn Y. The yarn accumulation section can be a yarn accumulator roller. When a yarn accumulator roll is used as the yarn accumulation section, the yarn supply device 4 can be omitted.
[0020] The monitoring device of a yarn 50 according to the first embodiment is explained in detail below. As illustrated in fig. 2, the monitoring device of a yarn 50 comprises a detection module 51, a control substrate 52 and a housing 53. The control substrate 52 is arranged so that a mounting surface 52s thereof is orthogonal to the direction of sliding of the yarn Y. The housing 53 houses the control substrate 52 and the detection module 51.
[0021] As shown in fig. 3, in fig. 4 and in fig. 5, the detection module 51 comprises a support (support element) 54. The support 54 has a sliding region R1 through which the yarn Y is made to slide and an introduction region R2 from which the yarn Y is introduced by the outside in the sliding region R1. The sliding region R1 is a space extending along the sliding path of the yarn Y. The introduction region R2 is a space which opens towards the front side of the sliding region R1 (the side from which the end of the yarn of the yarn Y coming from the winding device 7 is guided by the suction mouth 22 in the case of cutting of the yarn Y). This means that the introduction region R2 is a space from which the yarn Y is introduced into the sliding region R1, and it is also a space that connects the sliding region R1 with an outer space. The sliding region R1 and the introduction region R2 are continuous with each other.
[0022] The support 54 comprises a first wall element 55, a second wall element 56 and an inner wall element 57. The first wall element 55 and the second wall element 56 are facing each other. another on the opposite sides of the sliding region R1. The inner wall element 57 connects the first wall element 55 to the second wall element 56. The inner wall element 57 is in front of the introduction region R2 on the other side of the sliding region R1. The first wall element 55, the second wall element 56 and the inner wall element 57 are integrally made, for example, of resin. The shape of each of the first wall element 55, the second wall element 56 and the inner wall element 57 is not restricted to the shape of a plate; that is, these wall elements may have other shapes.
[0023] As shown in fig. 3 and in fig. 4, the support 54 supports a light-emitting element 61, consisting of an LED and the like, and of the light-receiving elements 62, 63, 64, consisting of photodiodes and the like, in a part 54a arranged upstream of the direction of sliding of the yarn Y. The light-emitting element 61 and the light-receiving elements 62, 63, 64 are each arranged so as to be able to detect the state of the yarn Y flowing in the sliding region R1. The light-emitting element 61 and the light-receiving elements 62, 63, 64 are each arranged in a different position around the sliding region R1, when observed from the sliding direction of the yarn Y. The state of the yarn Y is detected by a combined action of the light-emitting element 61 and the light-receiving elements 62, 63, 64.
[0024] When the light-emitting element 61 is caused to emit a light and the yarn Y flowing in the sliding region R1 is radiated with this light, a reflected light which is reflected by the yarn Y as part of the entire light emitted is received by the light receiving element 62 and the light receiving element 64, and a transmitted light which passes through the yarn Y as part of the entire emitted light is received by the light receiving element 63. When the yarn Y contains a foreign substance, the yarn monitoring device 50 detects the foreign substance on the basis of the optical intensities of the reflected lights picked up by each of the light-receiving element 62 and the light-receiving element 64. When the light-emitting element 61 emits a blue light, for example, it is possible to detect a foreign substance that is lighter (whitish, transparent and the like) than the Y yarn. Based on the The optical intensity of the transmitted light captured by the light receiving element 63 it is also possible to detect a thickness of the yarn Y, as observed from a direction orthogonal to the sliding direction of the yarn Y.
[0025] The light-emitting element 61 has a pair of feet (terminals) 61 a. The pins 61a extend in the opposite direction with respect to the sliding region R1 and are aligned along the sliding direction of the yarn Y. The light-receiving element 62 has a pair of feet (terminals) 62a. Similarly, the light-receiving element 63 has a pair of pins (terminals) 63a and the light-receiving element 64 has a pair of pins (terminals) 64a. The tips of the pins 62a are bent so as to extend in the opposite direction with respect to the sliding region R1 and are also aligned along the sliding direction of the yarn Y. The same applies to the feet 63a and the feet 64a.
[0026] As shown in fig. 3 and in fig. 5, the support 54 also supports the light-emitting elements 65 and 66, consisting of LEDs and the like, and the light-receiving elements 67 and 68, consisting of photodiodes and the like, in a part 54b arranged downstream of the direction for sliding the yarn Y. The light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 are arranged so as to detect the state of the yarn Y flowing in the sliding region R1. Each of the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 is arranged in a different position around the sliding region R1, when observed from the direction of sliding of the yarn Y. The state of the yarn Y is detected by a combined action of the light-emitting elements 65 and 66 and of the light-receiving elements 67 and 68.
[0027] The group of components consisting of the light-emitting element 61 and the light-receiving elements 62, 63, 64 is arranged in such a way that the relative optical axes fall into a plane orthogonal to the sliding direction of the yarn Y Furthermore, the group of components consisting of the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 is arranged so that the relative optical axes fall into a different plane orthogonal to the sliding direction of the yarn Y This means that, when observed from the direction orthogonal to the direction of sliding of the yarn Y, the group of components constituted by the light-emitting elements 65 and 66 and by the light-receiving elements 67 and 68 is arranged at a different level with respect to the level of the component group consisting of the light-emitting element 61 and the light-receiving elements 62,63,64. In this way, when observed from the direction orthogonal to the direction of sliding of the yarn Y, the group of components constituted by the light-emitting element 61 and the light-receiving elements 62, 63, 64 and the group of components constituted by the elements of light emission 65 and 66 and from the light receiving elements 67 and 68 are arranged at different levels to each other. This means that the yarn monitoring device 50 has a two-stage configuration. The group of components consisting of the light-emitting element 61 and the light-receiving elements 62, 63, 64 and the group of components consisting of the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 , when observed from the sliding direction of the yarn Y, they are arranged inside a region which is surrounded by a circuit substrate 70 around the sliding region R1.
[0028] The light-emitting element 65 and the light-emitting element 66 are emitted in alternating phases. When the light-emitting element 65 is induced to emit light and the yarn Y flowing in the sliding region R1 is irradiated with this light, a reflected light which is reflected by the yarn Y as part of the entire emitted light is received by the light receiving member 67, and transmitted light passing through yarn Y as part of the entire emitted light is received by the light receiving element 68. On the other hand, when the light emitting element 66 is induced to emit light and the yarn Y flowing in the sliding region R1 is irradiated with this light, a reflected light which is reflected by the yarn Y as part of the entire emitted light is received at the light receiving element 68, and a transmitted light passing through the yarn Y as part of the entire emitted light is received by the light-receiving element 67. When the yarn Y contains a foreign substance, the device yarn monitoring facility 50 detects the foreign substance based on the optical intensities of the reflected lights picked up by the light receiving element 67 and the light receiving element 68. When the light emitting element 65 is the element of light emission 66 they emit yellow lights, for example, it is possible to detect a foreign substance that is darker (blackish and similar) than yarn Y. Based on the optical intensities of the transmitted lights captured by the light-receiving element 67 and by the the light receiving element 68 it is also possible to detect the thicknesses of the yarn Y, as observed from two directions orthogonal to the sliding direction of the yarn Y.
[0029] The light-emitting element 65 has a pair of feet (terminals) 65a and the light-emitting element 66 has a pair of feet (terminals) 66a. The pins 65a extend in the opposite direction with respect to the sliding region R1 and are aligned along the sliding direction of the yarn Y. The same applies to the pins 66a. The light receiving element 67 has a pair of feet (terminals) 67a and the light receiving element 68 has a pair of feet (terminals) 68a. The tips of the pins 67a are bent so as to extend in the opposite direction with respect to the sliding region R1 and are also aligned along the sliding direction of the yarn Y. The same applies to the pins 68a.
[0030] As shown in fig. 3, in fig. 4 and in fig. 5, the detection module 51 comprises the circuit substrate 70. The circuit substrate 70, when viewed from the direction of sliding of the yarn Y in a condition in which the introduction region R2 is open, is arranged so as to surround the first wall element 55, the second wall element 56 and the inner wall element 57. The circuit substrate 70, when viewed from the direction of sliding of the yarn Y, is arranged around the sliding region R1. Specifically, the circuit substrate 70, when viewed from the direction of sliding of the yarn Y, is arranged so as to surround a part of the sliding region R1. It is permissible not to surround at least one part of each between the first wall element 55 and the second wall element 56 facing the introduction region R2 with the circuit substrate 70. In this way, the circuit substrate 70, when viewed from the sliding direction of the yarn Y, does not necessarily have to surround the entire sliding region R1. Moreover, the circuit substrate 70, when viewed from the direction orthogonal to the sliding direction of the yarn Y, does not necessarily have to surround the entire sliding region R1.
[0031] As shown in fig. 3 and in fig. 4, the mounting elements 71,72, 73, 74 of the circuit substrate 70 are fixed with screws and the like in the part 54a located upstream in the support 54.1 pins 61 a of the light-emitting element (first electronic component) 61 are connected by welding and similar to the mounting element (first mounting element) 71. The pins 62a of the light receiving element (second electronic component) 62 are connected by welding and similar to the mounting element (second mounting element ) 72.1 pins 63a of the light receiving element 63 are connected by welding and similar to the mounting element 73. the pins 64a of the light receiving element 64 are connected by welding and similar to the mounting element 74. In this way , the light-emitting element 61 and the light-receiving elements 62, 63, 64 are mounted respectively on the mounting elements 71,72, 73, 74.
[0032] The mounting element 71 is electrically connected to the mounting element 72 with a wiring element (first wiring element) 81. The mounting element 71 is electrically connected to the mounting element 74 with an element of wiring 82. The mounting element 74 is electrically connected to the mounting element 73 with a wiring element 83.
[0033] As shown in fig. 3 and in fig. 5, the mounting elements 75, 76, 77, 78 of the circuit substrate 70 are fixed with screws and the like in the part 54b located downstream in the support 54. The pins 65a of the light-emitting element (third electronic component) 65 are connected by welding and the like to the mounting element (third mounting element) 75.1 the legs 66a of the light-emitting element 66 are connected by welding and similar to the mounting element 76. The pins 67a of the receiving element of the light (fourth electronic component) 67 are welded and similar to the mounting element (fourth mounting element) 77. The pins 68a of the light receiving element 68 are connected by welding and similar to the mounting element 78. In this way, the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 are respectively mounted on the mounting elements 75, 76, 77, 78.
[0034] The mounting element 75 is electrically connected to the mounting element 77 with a wiring element (second wiring element) 84. The mounting element 75 is electrically connected to the mounting element 76 with an element of wiring 85. The mounting element 76 is electrically connected to the mounting element 78 with a wiring element 86.
[0035] As shown in fig. 3, in fig. 4 and in fig. 5, each of the mounting elements 72.73, 74.76, 77, 78 constitutes a distinct rigid substrate (rigid element). The mounting element 71 and the mounting element 75 are aligned along the sliding direction of the yarn Y and are also arranged on a plane parallel to the sliding direction of the yarn Y. In this condition, the mounting element 71 and the mounting element 75 is arranged on a shared substrate 79 consisting of a shared rigid substrate (rigid element). A mounting surface 79s of the shared substrate 79 is substantially orthogonal to the mounting surface 52s of the control substrate 52 (see FIG. 2). Each of the wiring elements 81,82, 83, 84, 85, 86 forms a separate flexible substrate (flexible element). In this way, in the circuit substrate 70, a rigid substrate is connected by a flexible substrate to the part of the shared substrate 79 which is upstream with respect to the sliding direction of the yarn Y, and a rigid substrate is connected by a flexible substrate to the part of the shared substrate 79 which is located downstream of the direction of sliding of the yarn Y.
[0036] As a circuit substrate 70 it is possible to use a so-called rigid-flexible substrate. A rigid-flexible substrate is a substrate obtained by integrating together a rigid substrate, on which a connection scheme and through holes have been obtained, and a flexible substrate, on which a connection scheme has been obtained. The rigid substrate is made of a material with a high rigidity, such as epoxy glass. The flexible substrate is made of a material with high flexibility and flexibility, such as polyimide. Alternatively, the rigid substrate and the flexible substrate can be made of the same material, and the rigid substrate can be made thicker than the flexible substrate by increasing the number of layers in the rigid substrate. In summary, it is sufficient that the flexibility and the flexibility of the flexible substrate are greater than the flexibility and the flexibility of the rigid substrate.
[0037] The part of the circuit substrate 70 which surrounds the sliding region R1 (the mounting elements 71, 72, 73, 74, 75, 76, 77, 78 and the wiring elements 81, 82, 83, 84, 85, 86) is arranged so as to be parallel to the direction of sliding of the yarn Y. In this explanation, "parallel to the direction of flow of the yarn Y" means, with reference to components such as the wiring elements 81,82,83, 84, 85,86 which are curved, that a plane tangent to a curved surface of these components is parallel to the sliding direction of the yarn Y.
[0038] As shown in fig. 2, the circuit substrate 70 comprises a wiring element (third wiring element) 87 and a relay substrate 88 which electrically connects the shared substrate 79 to the control substrate 52. The wiring element 87 is connected to a marginal part (a marginal part upstream from the direction of flow of the yarn Y in the first embodiment) of the shared substrate 79 and a part (an edge part of the shared substrate 79) of a marginal part (a marginal part upstream with respect to the direction of sliding of the yarn Y in the first embodiment) of the wiring element 82. The relay substrate 88 is connected to the edge of the wiring element 87 facing the control substrate 52. The circuit substrate 70 is electrically connected to the substrate of control 52 connecting a connecting element 88a arranged on the relay substrate 88 to a connecting element 52a mounted on the control substrate 5 2. In this structure, through the circuit substrate 70, the control substrate 52 performs the input / output of electrical signals to / from a group of components consisting of the light-emitting element 61 and the light-receiving elements 62, 63, 64, as well as to / from a group of components consisting of the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68, and processes the electrical signals. It should be noted that only the connecting element 88a or only the connecting element 88a and a resistance element can be mounted on the relay substrate 88. Moreover, the wiring element 87 can be mounted only on the marginal part (the marginal part upstream with respect to the direction of sliding of the yarn Y in the first embodiment) of the shared substrate 79.
[0039] By way of reference, the detection module 51 having the configuration shown above can be assembled as explained below. First, for example, the various elements 61 to 68 are fixed to the support 54 by inserting the elements 61 to 68 in the recesses and / or holes formed in the support 54. Subsequently the circuit substrate 70 is placed around the support 54 and the feet are inserted from 61 to 68a of the elements 61 to 68 in the corresponding holes formed in each of the mounting elements 71 to 78. In this condition, the mounting elements 71 to 78 are fixed to the support 54 by means of screws and the like. If the holes in the mounting elements 71 to 78 are formed so as to extend in the direction (a direction from which the circuit substrate 70 surrounds the sliding region R1) which is orthogonal to the sliding direction of the yarn Y, the The operation of inserting the pins 61 to 68a of the elements 61 to 68 into the corresponding holes of the mounting elements 71 to 78 is easy to perform. Furthermore, creating around the support 54 a projection which serves to prevent rotation and obtaining in each of the mounting elements 71 to 78 a notch and / or a hole in which the projection can be inserted, it is possible to avoid the co-rotation of the elements. assembly 71 to 78 when the mounting elements 71 to 78 are fixed to the support 54 by means of screws and the like. Finally, the feet 61 to 68a of the elements 61 to 68 are connected to the connection diagrams of the assembly elements 71 to 78 by welding and the like.
[0040] As already explained, in the monitoring device of a yarn 50 according to the first embodiment, the light-emitting element 61 and the light-receiving elements 62, 63, 64 are respectively mounted on the mounting elements 71, 72, 73, 74 of the circuit substrate 70. Similarly, the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 are respectively mounted on the mounting elements 75, 76, 77, 78 of the circuit substrate 70. Therefore it is superfluous to weld the electrical cables to the feet of the elements and cover the connecting parts between the element feet and the electrical cables with an insulating element such as a heat-shrink tube. It is also possible to avoid an undesired situation in which the connecting parts between the feet of the elements and the electric cables are subjected to stress. The assemblability and durability of the monitoring device of a yarn 50 are therefore improved.
[0041] In this way, in the monitoring device of a yarn 50 according to the first embodiment, it is possible to efficiently carry out the installation and wiring of the various elements from 61 to 68 positioned on different planes. Moreover, since the detection module 51, in which the different elements 61 to 68, the circuit substrate 70 and the support 54 are formed in a single module, can be easily attached / detached to / from the control substrate 52, it is it is possible to easily perform inspection and / or replacement of the detection module 51.

Thanks to this configuration it is possible to easily position the elements 61 to 68 and to suitably maintain the mutual positions of the elements 61 to 68.
[0049] In the monitoring device of a yarn 50 according to the first embodiment, the circuit substrate 70, when viewed from the direction of sliding of the yarn Y in a condition in which the introduction region R2 is open, is arranged in such a way to surround the first wall element 55, the second wall element 56 and the inner wall element 57.

Thanks to this configuration, by arranging the introduction region R2 as well as the sliding region R1 on the support 54, it is possible to effectively arrange the elements 61 to 68 on the support 54. Moreover , since the light-emitting element 61 and the light-emitting element 65 can be mounted on the shared substrate 79, it is possible to easily perform the connection operation (welding and the like) of the pins 61 a and 65a of the emission elements of ports 61 and 65 to the shared substrate 79.

[0054] The spinning unit 1 which constitutes the spinning machine 10 which consists of the winding machine of a yarn according to the first embodiment comprises the illustrated device for monitoring a yarn 50 according to the first embodiment.

As illustrated in fig. 6, excluding the fact that both the part 54a placed upstream and the part 54b located downstream in the support 54 of the detection module 51 according to the second embodiment have the same configuration (ie the configuration which includes the emission elements of the light 65 and 66 and the light receiving elements 67 and 68, as well as the mounting elements 75, 76, 77, 78 and the wiring elements 84, 85, 86 of the circuit substrate 70) of the downstream part 54b in the support 54 of the detection module 51 according to the first embodiment, the configuration of the detection modules 51 according to the first and the second embodiment is the same. In the upstream part 54a, the group of components consisting of the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 is arranged so that the relative optical axes fall into a plane orthogonal to the sliding direction of the yarn Y.

The group of components consisting of the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68, when viewed from the direction of sliding of the yarn Y, is arranged inside a region surrounded by the circuit substrate 70 around it to the sliding region R1.
[0056] The circuit substrate 70 comprises a first circuit part 70A and a second circuit part 70B. The first part of the circuit 70A comprises the mounting elements 75, 76, 77, 78 and the wiring elements 84, 85, 86 which are arranged in the part 54a located upstream in the support 54. The second part of the circuit 70B comprises the elements assembly 75, 76, 77, 78 and the wiring elements (fourth wiring element) 84, 85, 86 which are arranged in the part 54b located downstream in the support 54. Each of the mounting elements 75 aligned in the sliding direction of the Y yarn is a separate rigid card (rigid element). Consequently, the first part of the circuit 70A and the second part of the circuit 70B are electrically and physically separated from one another.
[0057] The first part of the circuit 70A comprises the wiring element 87 and the relay substrate (first relay substrate) 88, which electrically connect the mounting element 75 to the first control substrate 52A.

The first part of the circuit 70A is electrically connected to the first control substrate 52A connecting the connecting element 88a arranged on the relay substrate 88 to the connecting element 52a mounted on the first control substrate 52A. In this structure, through the first part of the circuit 70A, the first control substrate 52A performs the input / output of electrical signals to / from the group of components constituted by the light-emitting elements 65 and 66 and by the light-receiving elements 67 and 68 arranged on the part 54a located upstream in the support 54, and processes the electrical signals. It should be noted that the wiring element 87 can be mounted only on the marginal part (the marginal part upstream with respect to the sliding direction of the yarn Y in the second embodiment) of the mounting element 75.

The relay substrate 88 is connected to the edge of the wiring element 87 facing the second control substrate 52B. The second circuit portion 70B is electrically connected to the second control substrate 52B connecting the connecting element 88a arranged on the relay substrate 88 to the connecting element 52a mounted on the second control substrate 52B. In this structure, through the second part of the circuit 70B, the second control substrate 52B performs the input / output of electrical signals to / from the group of components constituted by the light-emitting elements 65 and 66 and by the light-receiving elements 67 and 68 arranged on the part 54b located downstream in the support 54, and processes the electrical signals.

However it is possible to have a configuration in which the mounting surface 52s of the first control substrate 52A is facing downstream in the sliding direction of the Y yarn and the mounting surface 52s of the second control substrate 52B is facing upstream in the direction of sliding of the yarn Y. Furthermore, it is possible to have a configuration in which the mounting surface 52s of the first control substrate 52A is facing upstream in the direction of flow of the yarn Y and the mounting surface 52s of the second control substrate 52B is facing downstream in the direction of sliding of the yarn Y. Furthermore, it is possible to have a configuration in which both the mounting surface 52s of the first control substrate 52A and the mounting surface 52s of the second control substrate 52B face upstream in the sliding direction of the Y yarn.

Similarly, the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 are respectively mounted on the mounting elements 75, 76, 77, 78 of the circuit substrate 70. Therefore it is superfluous to weld the electrical cables to the feet of the elements and cover the connecting parts between the element feet and the electrical cables with an insulating element such as a heat-shrink tube. It is also possible to avoid an undesired situation in which the connecting parts between the feet of the elements and the electric cables are subjected to stress. The assemblability and durability of the monitoring device of a yarn 50 are therefore improved.
[0061] In the monitoring device of a yarn 50 according to the second embodiment it is possible to detect different states of the yarn with the group of components consisting of the light-emitting element 61 and the light-receiving elements 62, 63, 64 arranged on the part 54a located upstream in the support 54 and with the group of components consisting of the light-emitting elements 65 and 66 and the light-receiving elements 67 and 68 arranged on the part 54b located downstream in the support 54. In this context, different yarn states are, for example, the thickness of the yarn and the presence / absence of a foreign substance in the yarn. Moreover, since the first part of the circuit 70A and the second part of the circuit 70B are electrically and physically separated from each other, the degree of freedom in positioning the group of components constituted by the light-emitting element 61 and by the light receiving elements 62, 63, 64, as well as the group of components consisting of the light emitting elements 65 and 66 and the light receiving elements 67 and 68.

Similarly, the second circuit portion 70B is electrically connected to the second control substrate 52B connecting the connecting element 88a to the connecting element 52a. Thanks to this configuration, it is possible to easily achieve the connection and electrical disconnection between the first part of the circuit 70A and the first control substrate 52A. Furthermore it is possible to easily achieve the connection and electrical disconnection between the second circuit part 70B and the second control substrate 52B.

Moreover, the number of elements that constitute the group of the light-emitting element and the light-receiving element arranged in a position, when observed from the direction orthogonal to the direction of sliding of the yarn, is not restricted to four, but the the number of elements may instead be equal to or greater than five, or be two or three. The detection module 51 illustrated in fig. 7 is an example in which a group consists only of a pair of light-emitting element 61 and light-receiving element 62 positioned facing each other in a single position, if observed from the direction orthogonal to the sliding direction of yarn Y, on opposite sides of the sliding region R1.

Moreover, the electronic components used here for detecting the state of the yarn flowing in the sliding region are not limited to the components that have pins as terminals; the components can instead be components for surface mounting that have pad electrodes as terminals.
[0065] Furthermore, there is no limit which imposes, as in the first and second embodiments, that an electronic component is mounted on a rigid substrate (rigid element) of the circuit substrate, but different electronic components can instead be mounted on a rigid substrate (rigid element) of the circuit substrate. The mounting element on which the electronic component is mounted does not necessarily have to be limited to the rigid substrate (rigid element), but can be a flexible substrate (flexible element). Furthermore, the electrical connection between the circuit substrate and the control substrate is not limited to that indirectly achieved through the relay substrate, but can be made directly, for example by providing the connecting element 88a on the wiring element 87 and connecting the wiring element 87 to the control substrate 52.
