Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cutting foil yarn cutting device in which one end portion of each cutting foil yarn, which is sequentially separated from the ear portion of the cutting foil paper and sent out, is attached to the cutting foil yarn cutting device. The present invention relates to a device for accurately positioning a cutting foil yarn side-by-side standby part located in an extension part of a sending part and its adjacent part.

[Conventional technology]

Conventionally, one end of a cutting foil yarn is merely transferred by a yarn feeding means of a cutting foil yarn cutting device toward a yarn side loading standby portion located at an extension of the yarn feeding portion of the cutting foil yarn cutting device. Accurate positioning has not been performed on the insertion waiting portion and its adjacent portion.

[Problems to be solved by the invention]

However, the transfer of one end portion of such a cutting foil yarn to the yarn side loading standby portion through the yarn feeding means of the cutting foil yarn cutting device is performed because the cutting foil yarn has flexibility and the like. And the adjacent part of the cutting foil may be laterally (laterally) displaced from the device, and one end of the cutting foil by a thread holder for mounting the cutting foil into the cutting foil horizontal loading device (drawing device). In some cases, it is not possible to grasp the part, and there is a problem in that it is sometimes impossible to detect the inside-out of the cutting foil by photoelectric sensors or the like provided in the adjacent part of the yarn side loading standby part.

Therefore, the present invention also aims to accurately position one end of the cutting foil yarn at the yarn side loading standby portion and its adjacent portion.

[Means for solving problems]

According to this invention, the above-mentioned object is to install a yarn support base between the yarn sending-out part and the yarn side-by-side standby part of the cutting foil yarn cutting device,
A pair of positioning sliders interlockingly connected to the thread supporting base via a swing lever so as to be able to approach and separate from each other are horizontally arranged with a cutting foil thread positioning line connecting a thread sending-out section of a cutting foil thread cutting device and a thread side loading standby section interposed therebetween. Springs that are mounted so as to oppose each other in the direction and urge the pair of positioning sliders toward or away from the positioning slider or the swing lever, and the pair of positioning sliders are separated from each other against the action force of the springs. Or close / separate operation (drive)
This is achieved by means of a locating device for the slicing foil thread which engages means.

Here, the pair of positioning sliders are installed adjacent to each other in the front-back direction in the extending direction of the cutting foil thread positioning line, and at the mutually opposing portions, the opposite ends of the pair of positioning sliders and the upper end of the thread support base are provided. And a pair of positioning guides having guide cavities that open as a bottom point (most concave point) corresponding to and, or a support pin at the upper end of each, when the two positioning sliders approach each other, the lower end is the thread support base. It is possible to attach a positioning assisting means such as a thread retainer that lowers the thread to a position corresponding to the upper end of the thread and raises it above the thread support base when the positioning sliders are separated.

[Action]

In the positioning device of the cutting foil yarn of the present invention, the pair of positioning sliders are oscillated against the action force of the spring or with the action force of the spring by setting the contacting / separating operation means in the action or non-action state. In the state in which they are separated from each other through the interlocking by the moving lever, the tip of the cutting foil thread is passed between the pair of positioning sliders by the thread feeding means of the cutting foil thread cutting device, on the thread support base, to the thread horizontal loading standby section. After the transfer, the contacting / separating operation means is brought into the inactive or inactive state, so that the pair of positioning sliders are interlocked by the rocking levers with or without the acting force of the spring. Approach each other through.

As a result, the leading end portion of the cutting foil yarn and its adjacent portion are guided to the cutting foil yarn positioning line, and the leading end portion is accurately positioned in the yarn horizontal loading standby portion and its adjacent portion.

When a pair of positioning guides and a thread retainer as described above are attached to the pair of positioning sliders, the thread guide space formed by the thread guide depressions formed by both guide depressions of the pair of positioning guides, or the thread retainer and both positioning sliders are formed. The yarn guide space formed by the opposite end faces of the squeeze converges toward the cutting foil yarn positioning line. The positioning of this crystal cutting foil yarn is facilitated.
