The portions of the covers 116 and 117 that intersect the straight line connecting the light receiving element 63 and the light projecting element 113 are formed so as to have translucency (preferably transparent).

  When the yarn joining cart control unit grasps that the yarn joining cart 110 is located in front of the target spinning unit 3 as a result of optical wireless communication by the light receiving element 63 and the light projecting device 113, the yarn joining operation is performed. Each part of the splicer 111, the suction mouse, the suction pipe, and the like is controlled so that

<Optical wireless communication>
When the light receiving element 63 provided on the control board 63 of each spinning unit 3 receives the light projected from the light projecting element 113 provided on the yarn joining carriage 110, the yarn joining carriage 110 and each spinning unit 3 are received. Optical wireless communication is performed between the two. By this optical wireless communication, information such as the current position of the yarn joining cart 110 and the timing of yarn joining is acquired.

  A part of the communication direction in the optical wireless communication space formed between the light projecting element 113 and the light receiving element 63 is formed in a shape extending along the communication direction so as to secure an optical communication path. A tunnel member (optical communication path securing member) 200 is provided. The communication direction here refers to the light projecting element 113 of the yarn splicing carriage 110 and the light receiving element 63 of the one spinning unit 3 when the yarn splicing carriage 110 is at a predetermined position facing one spinning unit 3. Means the communication direction formed between the two. Further, the predetermined position where the yarn splicing carriage 110 faces one spinning unit 3 is not limited to the position where the yarn splicing carriage 110 and one spinning unit 3 face each other in front (in other words, (This is not limited to the case where the yarn splicing carriage 110 is in the position immediately behind in the machine front-rear direction of one spinning unit 3), and the light receiving element 113 of the yarn splicing carriage 100 and the light receiving of the one spinning unit 3. Any position where optical wireless communication is possible with the element 63 may be used.

Moreover, the insertion part 220 for inserting in the communication hole 64a is formed in the one end part of the extension direction of the tunnel member 200. As shown in FIG. The insertion part 220 has an upper wall and left and right side walls, like the main body part 210. Each wall of the insertion part 220 is formed by extending each wall of the main body part. However, the left and right side walls of the insertion portion 220 are formed to have a smaller cross-sectional area than that of the main body 210 so as to match the size and shape of the communication hole 64a.

  The tunnel member 200 is placed on the placement surface 65 so as to form a space S surrounded by the placement surface 65 with the insertion portion 220 inserted into the communication hole 64a.

  In the spinning machine 1, as shown in FIG. 3, the front panel 60 and the placement surface 65 are installed with an inclination with respect to the horizontal plane, and the light receiving element 63 and the light projecting element 113 are also positioned on the same horizontal plane. Instead, it is configured to be shifted in the vertical direction. Accordingly, corresponding to the configuration of the spinning machine 1, the tunnel member 200 is appropriately shaped so that a straight line connecting the light receiving element 63 and the light projecting element 113 is located in the space S formed by the tunnel member 200. It is formed and installed. That is, the shape of the tunnel member 200 illustrated in FIG. 4 is merely an example, and the positional relationship between the light receiving element 63 and the light projecting element 133 during communication and the relationship between the light receiving element 63 and the light projecting element 133 are described. The optical wireless communication space can be variously modified in accordance with the state of the optical wireless communication space (the state of devices arranged on the optical communication path, the partition wall, the mounting surface, etc.).

  The color and material of the tunnel member 200 can be variously set within a range that does not hinder optical wireless communication. That is, the tunnel member 200 does not need to be formed to have translucency like the covers 116 and 117 installed in the vicinity of the light receiving element 63, and may be formed transparent, but transmits light. For example, it may be formed by being colored in black or blue. Moreover, it may be formed of, for example, acrylic or glass, or may be formed of, for example, plastic colored in black or blue.

<Action and effect>
According to the spinning machine 1 including the tunnel member 200 configured as described above, the placement surface 65 is located below the draft portion 10, so that the fluff easily accumulates. Since the space S is formed so as not to invade the fluff, an optical communication path is always secured between the light projecting element 113 and the light receiving element 63, and optical wireless communication is performed by a foreign matter such as fluff. Can be prevented from being disturbed.

  Further, the simple configuration in which the tunnel member 200 is placed on the placement surface 65 can prevent the optical wireless communication interference due to the fluff.

  As shown in FIG. 5, there is a case where a gap G is formed between the partition wall 64 and the mounting surface 65 on the back surface of the front panel 60. In this case, there is a possibility that the fluff blows up from below through the gap G, and the optical wireless communication is disturbed. Therefore, for such a case, as shown in FIGS. 5 and 6, an optical communication path is secured by using a tunnel member 300 in which a bottom wall 330 is newly provided so as to close the gap G. good. The tunnel member 300 has the same configuration as that of the tunnel member 200 except that the bottom wall 330 is provided.

  The bottom wall 330 may be limited to a position corresponding to the gap G, or may be provided over the entire bottom surface.

  The tunnel members 200 and 300 are formed such that a cross-sectional shape cut perpendicularly to the extending direction (in other words, a cross-sectional shape in a direction intersecting the communication direction) is a groove shape (channel). However, as shown in FIG. 7, a tunnel member 400 in which the cross-sectional shape is formed in a mountain shape may be used. Moreover, as shown in FIG. 8, the tunnel member 500 in which the cross-sectional shape is formed in an arc shape may be used.

[Second Embodiment]
In the present embodiment, the tunnel member 200 of the first embodiment is changed to a solid member 600 as shown in FIGS. 9 and 10 to secure an optical communication path between the light receiving element 63 and the light projecting element 113. It is a thing. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

  As shown in FIG. 10, the solid member 600 of the present embodiment has a main body 610 formed in a prismatic shape extending along the communication direction. Moreover, the insertion part 620 for inserting in the communication hole 64a is formed in the one end part of the extending direction of the solid member 600. As shown in FIG. The insertion part 620 is formed by extending the shape of the main body part 610 as it is. The main body portion 610 and the insertion portion 620 are formed in a simple shape because all of the light entering from the other end portion (light emitting side) of the solid member 600 goes out from one end portion (light receiving side). It is desirable that Accordingly, a mounting portion 630 is provided on the bottom surface of the solid member 600 separately from the main body portion 610 and the insertion portion 620, and the insertion portion 620 is placed in a state where the insertion portion 620 is inserted into the communication hole 64a. It is placed stably on the surface 65. The attachment portion 630 is formed so as not to affect light transmission. In addition, the shape of the attachment part 630 shown in FIG. 9 is an example, and is not limited to this. Further, the attachment portion 630 is an omissible portion when the solid member 600 can be stably placed on the placement surface 65 without the attachment portion 630. That is, depending on the installation state of the solid member 600, the shape of the attachment portion 630 can be variously set, and further, the attachment portion 630 itself may not be provided.

  It is more preferable that the solid member 600 is made of a light-transmitting substance and is transparent so that light can pass through satisfactorily. That is, it is preferable that the solid member 600 is made of acrylic or glass, for example. Moreover, it is preferable that the surface of the solid member 600 (excluding the surfaces at both ends in the communication direction) is coated so as to lack translucency. As the coating agent, for example, titanium oxide or aluminum can be used. If coated in this way, light can be transmitted through the interior having translucency, while the light passing through the interior is reflected on the inner side while blocking the influence of external light by the non-translucent surface. Communication performance can be improved.

  According to the spinning machine 1 including the solid member 600 configured as described above, since the light projected from the light projecting element 113 passes through the solid member 600, the fluff is placed on the placement surface 65. It is possible to prevent the optical wireless communication from being disturbed by the accumulation of. Further, since the light passes through the solid member 600, there is an advantage that the light receiving sensitivity of the light receiving element 63 is increased.

  In the actual configuration of the spinning machine 1, the front panel 60 and the mounting surface 65 are inclined with respect to the horizontal plane, and the light receiving element 63 and the light projecting element 113 are not positioned on the same horizontal plane. Yes. Therefore, in order to correspond to such a configuration, as shown in FIG. 11, the solid member 600 ′ is formed by being bent at the boundary surface between the main body portion 610 ′ and the insertion portion 620 ′. It is preferable.

  Further, depending on the configuration of the spinning machine 1, the light projecting element 113 and the light receiving element 63 may be installed so that the light receiving element 63 cannot be directly visually recognized from the light projecting element 113. For such a configuration, as shown in FIG. 12, the solid member 700 is bent in the middle, and light entering from the end portion 700a on the translucent element 113 side is included in the bent portion. It is preferable that a reflection surface 740 is formed so as to reflect the light and guide it to the end 700b on the light receiving element 63 side.

  Further, it may be a solid member 800 formed in a columnar shape as shown in FIG. 13, or a medium in which the cross-sectional shape is circular and the middle is curved as shown in FIG. 14. It may be a real member 800 ′.

  That is, the configuration of the solid members 600, 600 ′, 700, 800, 800 ′ is such that the positional relationship between the light projecting element 133 and the light receiving element 63 during communication and the light between the light projecting element 133 and the light receiving element 63 are the same. Various settings can be made according to the state of the wireless communication space (the state of the devices arranged on the optical communication path, the partition wall, the mounting surface, etc.), for example, the insertion in the solid member 600 ′ shown in FIG. The portion 620 ′ is bent in the vertical direction, but may be bent in the horizontal direction, or may be bent in the vertical and horizontal directions.

[Others]
As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention.

  For example, in the above embodiment, one yarn joining cart 110 is provided for one spinning machine 1, but a plurality of yarn joining carts 110 may be provided according to the number of spinning units 3.

  In the above embodiment, the insertion portions 220, 620, and 620 ′ for insertion into the communication hole 64a are formed at the light receiving side ends of the tunnel members 200 and 300 and the solid members 600 and 600 ′. Such insertion parts 220, 620, 620 'may not be formed. In this case, it is preferable that the light receiving side end face of the tunnel member or the solid member is installed so as to face the communication hole 64a. However, even if it is a tunnel member or a solid member, the smaller the distance between the end portion on the light receiving side and the light receiving element 63 is, the more advantageous in terms of communication. Therefore, the partition wall 64 having the communication hole 64a. Is installed at a distance from the light receiving element 63, it is preferable to provide an insertion portion so that the distance between the light receiving element 63 and the end of the light receiving side of the tunnel member or solid member is as close as possible.

  If the light receiving side end of the tunnel member or the solid member and the light receiving element 63 are close to each other, the space in which foreign matter such as fluff accumulates between them becomes small, so even if fluff has accumulated between them. However, the amount of fluff that does not obstruct the passage of light is not reached, and stable optical wireless communication can be secured. As for the solid member, the closer the light receiving side end to the light receiving element 63 is, the more light that has passed through the inside of the solid member is scattered when it exits from the light receiving side end. In this respect, stable optical wireless communication can be ensured.
