Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a yarn splicing device that can automatically splice glass MIM yarns.

[Conventional technology]

In the production of glass fiber, several hundred single glass fibers (filaments) with a diameter of about 10 to 15 μm are bundled to form a raw thread (strand), which is then wound into a roughly cylindrical shape of a predetermined size for convenience of handling. There is.

Such a mass of yarn is generally called a cake in the industry, and this cake serves as a basic material for producing glass fiber products for various uses.

For example, when producing glass fiber for IAM reinforced plastic, in order to produce glass fiber of a predetermined thickness, raw threads are drawn from each of an appropriate number of cakes, and these are combined into one. It is rolled up into one roving. That is, the number of cakes to which raw yarn is simultaneously supplied to one roving is determined depending on how many raw yarns the required yarn thickness corresponds to. In the process, the required number of cakes for each roving is arranged on a cake shelf called a creel shelf, and the yarn is forcibly wound from each cake using a winder.

The threads on the outer surface of the cake may be discolored due to heat treatment during the manufacturing process. The thread that will not be wound onto the roving is supplied from the inner surface of the cake, so if you do not want to supply discolored thread to the roving, when the amount of remaining thread reaches a certain value, remove the old cake. It is necessary to replace the cake with a new one and tie the old and new threads together.

Further, even if there is no need to take into account discoloration of the thread, when the thread runs out, the next cake must be placed in a predetermined position on the creel shelf without delay and the old and new threads must be tied together. and,
The work of exchanging the old and new cakes, setting up the new cakes, and tying the new and old threads was done in thousands of steps by a worker who was monitoring the process.

[Invention or problem to be solved]

In the roving process, for example, several dozen cakes are often set for one roving, and the creel shelf typically has several tiers of such series. Therefore, one worker is in charge of a large number of cakes, and tying old and new threads when setting and replacing cakes is difficult! 71 speed was required, which resulted in severe fatigue for the workers, which was a problem. Furthermore, since the yarn is a glass knitted wire, it easily breaks, and manual splicing was originally very difficult.

The present invention was made to solve these problems, and its purpose is to automate the splicing operation in the above-mentioned roving process.

Next, the control system in the apparatus of this embodiment will be briefly explained.

In this example, in order to prevent the discolored threads on the outer surface of the cake 2 from entering the product, only the threads were drawn out from the inner surface of the cake 2 to a certain extent, and the weight of the cake became lighter than a certain limit. By the way, the old cake 2b and the new cake 2a are exchanged. The weight of the old cake 2b, which is the limit for replacement, should be determined to the extent that there is a small possibility that the discolored thread will be sent out in a low pink color, and also in consideration of the yield as a material.

The weight of each cake 2 in the creel shelf 1 is measured by a load cell, and the measurement data is sent to the ground-1 control panel 4.
The data is sent to a four-stage control panel such as a personal computer (not shown) via the controller. The ground control panel 4 is adapted to make decisions such as whether to replace the cake or to cut the thread based on these weight data. In other words, if the weight of the cake falls below the set value, it will be replaced, and if the weight of the cake decreases for a certain period of time, it will be assumed that the thread has broken and the thread has stopped feeding. to decide. Then, the ground control panel 4 controls the n7+ cake exchange device 6 based on this determination.
It is configured to control the process, perform regular cake exchange, and respond to abnormal situations such as thread breakage.

Next, the operation of the configuration described above will be explained.
