  As shown in FIGS. 3, 4, and 5, the detection module 51 includes a holder (support) 54. The holder 54 is provided with a travel region R1 for traveling the yarn Y and an introduction region R2 for introducing the yarn Y into the travel region R1 from the outside. The travel region R1 is a space that extends along the travel path of the yarn Y. The introduction region R2 is a space that opens to the front side of the traveling region R1 (the side on which the yarn end of the yarn Y on the winding device 7 side is guided by the suction mouse 22 when the yarn Y is cut). The travel region R1 and the introduction region R2 are continuous.

  The holder 54 has a first side wall portion 55, a second side wall portion 56, and a back wall portion 57.

The back wall portion 57 connects the first side wall portion 55 and the second side wall portion 56 and faces the introduction region R2 with the traveling region R1 interposed therebetween. The 1st side wall part 55, the 2nd side wall part 56, and the back wall part 57 are integrally formed, for example with resin. In addition, each shape of the 1st side wall part 55, the 2nd side wall part 56, and the back wall part 57 is not limited to flat form, Other shapes may be sufficient.

Is arranged.

  When the light emitting element 61 is caused to emit light and light is applied to the yarn Y traveling in the traveling region R1, the reflected light reflected by the yarn Y among the light is received by the light receiving element 62 and the light receiving element 64, and Of the light, transmitted light that has passed through the yarn Y is received by the light receiving element 63. In the yarn monitoring device 50, when a foreign matter is included in the yarn Y, the foreign matter can be detected based on the amount of light received by the light receiving element 62 and the light receiving element 64. For example, when the light emitting element 61 emits blue light, it is possible to detect a foreign matter having a color (white, transparent, etc.) brighter than the yarn Y. Further, the thickness of the yarn Y when viewed from one direction perpendicular to the traveling direction of the yarn Y can be detected based on the amount of light transmitted by the light receiving element 63.

  The light emitting element 61 has a pair of lead pins (terminals) 61a. The pair of lead pins 61a extends to the opposite side of the traveling region R1, and is arranged so as to be aligned along the traveling direction of the yarn Y.

Each of the light emitting elements 65 and 66 and the light receiving elements 67 and 68 has different positions around the traveling region R1 when viewed from the traveling direction of the yarn Y in order to detect the state of the yarn Y traveling in the traveling region R1. Is arranged.

  The set of the light emitting element 61 and the light receiving elements 62, 63, 64 is arranged such that the optical axis of each element is located on the same plane perpendicular to the traveling direction of the yarn Y. Further, the set of the light emitting elements 65 and 66 and the light receiving elements 67 and 68 are arranged so that the optical axis of each element is located on another same plane perpendicular to the traveling direction of the yarn Y. That is, the set of the light emitting elements 65 and 66 and the light receiving elements 67 and 68 is at a position different from the set of the light emitting element 61 and the light receiving elements 62, 63, and 64 when viewed from a direction perpendicular to the traveling direction of the yarn Y.

  The light emitting element 65 and the light emitting element 66 are made to emit light alternately. When the light emitting element 65 emits light and light is applied to the yarn Y traveling in the traveling region R1, the reflected light reflected by the yarn Y of the light is received by the light receiving element 67, and the yarn out of the light. The light transmitted through Y is received by the light receiving element 68. On the other hand, when the light emitting element 66 is caused to emit light and light is applied to the yarn Y traveling in the traveling region R1, reflected light reflected by the yarn Y among the light is received by the light receiving element 68, and the light The light transmitted through the yarn Y is received by the light receiving element 67. In the yarn monitoring device 50, when a foreign matter is included in the yarn Y, the foreign matter can be detected based on the amount of reflected light received by the light receiving element 67 and the light receiving element 68. For example, when the light emitting element 65 and the light emitting element 66 emit yellow light, it is possible to detect a foreign matter having a darker color (black or the like) than the yarn Y. Further, the thickness of the yarn Y when viewed from two directions perpendicular to the traveling direction of the yarn Y can be detected based on the amount of received light transmitted by the light receiving element 67 and the light receiving element 68.

Yes. Note that at least a part of each of the first sidewall portion 55 and the second sidewall portion 56 on the introduction region R2 side may not be surrounded by the circuit board 70. Thus, the circuit board 70 does not necessarily need to surround the entire region of the traveling region R1 when viewed from the traveling direction of the yarn Y. Further, when viewed from a direction perpendicular to the traveling direction of the yarn Y, the circuit board 70 does not necessarily need to surround the entire region of the traveling region R1.
