Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass fiber pulling device, and more particularly to a glass fiber pulling device equipped with an anti-static device for collecting glass fibers into a predetermined tray.

Glass fibers have various uses, but for example, they are used as a material for glass bonding, such as the core joint surface of a magnetic head. Conventionally, this glass fiber was obtained using a glass fiber pulling device shown in Figure 1. . In the figure, 1, 2
is a roller, and 3 is a glass fiber. The molten glass is made into a thin strip through a nozzle (not shown) and pulled up between these rollers 1 and 2 to form a glass fiber 3.The resulting glass fiber 3 is broken by hand into the required length. It was available for use. However, in this method, the glass fiber 3 could not be cut to a certain length because it was done manually, resulting in poor yield and poor working efficiency.

In order to solve this problem, as shown in Fig. 2, a cutter section 4 is formed by embedding a sharpened metal rod into the roller 1, and the glass fiber 3 pulled up by the cutter section 4 is cut to a certain length. A device for cutting was devised. With this device, it is possible to cut to a desired length by changing the diameter of the roller 1, and it is also possible to cut to a desired length by increasing or decreasing the number of cutter portions 4 of the roller 1. It is possible. Moreover, by attaching the guide 5, it was also possible to collect the cut glass fibers 3 in a fixed place. However, the above-mentioned improved device has the disadvantage that the glass fiber 3 is charged with static electricity, so that the glass fiber 3 does not fit into a predetermined receiving tray and scatters around.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, automatically cut the glass fibers 3 to a certain length, and collect the cut glass fibers 3 in a predetermined tray. Let's explain by example.

In FIG. 3, 1 and 2 are rollers that sandwich the glass fiber 3 discharged from the nozzle 7.
Pull upward. Reference numeral 4 denotes a cutter section which is a cutter embedded in one of the rollers 1, and is embedded with a sharply processed rod-shaped, plate-shaped member made of metal or other hard material. Reference numeral 5 denotes a guide for guiding the glass fiber 3 that has passed between the rollers 1 and 2, and for storing the cut glass fiber 3 in a tray (not shown).
Reference numeral 6 denotes an anti-static device. Although details are not shown, this anti-static device has a structure in which a plurality of electrodes are provided, and a high DC voltage is applied between the electrodes to generate a discharge phenomenon between the electrodes. be done. At this time, ions are generated by a discharge phenomenon. These ions are blown out to the outside using a fan or the like. The ions are sprayed onto the glass fiber 3 passing through the rollers 1 and 2 to neutralize the static electricity charged on the glass fiber 3, thereby removing and preventing the static electricity. Therefore, the glass fiber 3 is pulled up by the rotation of the rollers 1 and 2, automatically cut into a predetermined length, guided by the guide 5, and prevented from being charged, so that it is automatically placed in the receiving tray without scattering. will be collected.

As described above, according to the present invention, it is possible to collect the glass fibers 3 that have been automatically cut into a certain length in a predetermined tray without scattering them around, thereby improving work efficiency and yield. Additionally, since no complicated parts are used, there is a low possibility of failure and the product is inexpensive.
