Description

[Detailed description of the invention] The invention simplifies the wiring structure for electrical connection to the abnormal yarn sensing device used in camphor machines that handle a large number of yarns, such as various knitting machines and warping machines. Regarding current-carrying structure.

For example, various types of knitting machines such as stockinette knitting machines handle a large number of threads, and abnormalities in the threads used have a great impact on the quality of knitting of the fabric. An abnormal yarn sensing device (hereinafter simply referred to as the sensing device because it detects abnormal yarn tension, yarn breakage, large flames in the yarn, abnormal shape or irregularity of the slab portion, etc.) is installed on the knitting machine. When installing these sensing devices in the required locations, most of these sensing devices operate by electrical operation, so
Each sensing device must be wired for electrical connection.

At this time, in order to connect the current-carrying part of the sensing device to the electric wire on the power distribution side, it is necessary to strip off the covering of the covered wire and connect the bare wire parts, which, combined with the large number of sensing devices, requires a lot of time and effort. This is not only inefficient, but also prone to wiring errors.

The present invention is intended to solve these problems and to simplify and increase the efficiency of the energizing structure in the abnormality sensing device for a large number of yarns.The present invention is characterized by:
A support piece is erected at the top of the main body of the sensing device, which consists of a sensing member, a sensing mechanism, a signal transmitting member, etc., for sensing abnormalities such as tension changes, irregular shapes, and cuts in the yarn, and a support piece is provided at the upper end of the support piece. A U-shaped current-carrying contact portion is formed, and a pair of current-carrying pieces that are electrically connected to the sensing device body through an insulating material are arranged side by side on the U-shaped inner surface of the contact portion, and the whole is shaped like a long strip. A pair of current-carrying bands parallel to each other in the longitudinal direction of the band are arranged on the inner surface of the current-carrying member with an insulating material interposed therebetween, and the current-carrying contact portion of the support piece is fitted into the current-carrying member, and the pair The current-carrying piece is brought into contact with a pair of current-carrying bands of the current-carrying member.

The present invention will be described in detail with reference to the embodiments shown below. Fig. 1 is a perspective view of a sensing member in an embodiment of the device of the present invention, Fig. 2 is an exploded perspective view of the same essential parts, and Fig. 3 is a main part of an embodiment of the current-carrying member. front view,
Fig. 4 is a perspective view of the embodiment of the current-carrying member, and Fig. 5 is a side sectional view of the main parts. In Figs. A sensing member, a sensing mechanism, a signal transmitting member, etc. are installed on the outside of the main body 1, and a support piece 2 is mounted and fixed in a protruding manner, and a contact portion for energization is attached to the upper end of the support piece 2. 3.

As is clear from FIG. 2, the contact portion 3 has a bottom wall 4a, a side wall 4b, and a top wall 4c provided at the upper end of the support piece 2, which are formed in a substantially U-shape, and mounting holes 5, 6 at the top and bottom of the side wall 4b. is drilled,
a mounting portion 4 having a locking portion 4d formed at one end of the top wall 4C;
An insulating material 7 such as a plastic plate, a leaf spring-shaped current-carrying piece 89 made of a copper plate or the like attached to one side of the insulating material 7, and a locking piece 10 attached to the bottom wall 4a, The assembly involves fixing the insulating material 7 to the side wall 4b using the mounting holes 5 and the mounting screws 11, and attaching the current-carrying piece 8 to the front of the insulating material 7.
9 are fixed in parallel using the mounting holes 12 and the mounting screws 13, etc., and the base 10a of the L-shaped locking piece 10 is overlapped with the upper surface of the bottom wall 4a through the engagement of the locking claw 10b, and the opening claw 10c is A wall 10d having a wall 10d is made to stand up on the front surface of the U-shaped opening of the mounting part 4 in correspondence with the locking part 4d, and a mounting screw 14 inserted into the wall 10 through the mounting hole 6 of the side wall 4b is inserted through the screw hole 10e. It is fixed by screwing it in.

At this time, as shown in the second diagram, are there convex portions on the current-carrying pieces 7 and 8? a, 8
A may be provided to ensure reliable contact.

Furthermore, in the present invention, the structure illustrated in FIGS. 3 and 4 is used as the current-carrying member 15 to which the current-carrying contact portion 3 of the sensing device main body 1 is attached.

That is, the current-carrying member 15 includes an insulating material 15a made of a plastic plate or the like in the form of a long strip (the shape of the strip can be freely chosen, such as a straight line or a ring band), and a conductive member 15a that has an insulating material 15a on one side of the insulating material 15a over its entire length, for example. Similarly, long strip-shaped conductive strips 15b and 15C are laid in parallel by copper plating or printing.

Note that 16 indicates a fixing plate for the current-carrying member 15.

Further, the required connection terminal portions 17 and 18 on the side of the device main body 1,
- The current-carrying pieces 8 and 9 of the current-carrying contact portion 3 are connected in advance with lead wires 19 or the like.

According to the current-carrying structure of the present invention, for example, in the case of a knitting machine, the current-carrying member 15 of the present invention is arranged in advance around the outer periphery of the knitting machine, etc. Each energizing contact part 3 can be easily held and removed from the energizing member 15 by the locking piece 10 having a U-shape in the mounting part 4 and a wall led having a locking part 4d and an opening claw 10c. By fitting, the current-carrying pieces 8, 9 of the contact portion 3 come into contact with the current-carrying bands 15b, 15c of the current-carrying member 15,
Here an electrical connection with the power distribution side is obtained, allowing electrical operation of the sensing device.

That is, even when a large number of device bodies 1 are installed, energization can be obtained by fitting and supporting the energizing contact portion 3 attached to one end of the support piece 2. At this time, the sensing device body 1 is energized. Regardless of the position of the support piece 2 relative to the member 15, it is only necessary to consider the shape of the support piece 2 and provide it so that the current-carrying contact part 3 can be fitted therein. The time and effort of connecting each lead wire is completely eliminated, and the installation is quick, easy, and reliable.

Furthermore, it is easy to remove, and maintenance and inspection of the device is also facilitated, making it highly useful and excellent for various types of equipment that use this type of abnormal yarn sensing device.
