Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a cake exchanging device capable of automatically handling a cake, which is a mass of raw yarn before being rewound, in a yarn rewinding process in fiber production. It is about.

[Conventional technology]

In the production of glass fiber, hundreds of glass single fibers (filaments) having a diameter of about 10 to 15 μm are bundled into a raw yarn (strand), which is wound into a substantially cylindrical shape having a predetermined size for convenience of handling. Such a lump of raw yarn is generally called a cake in the art, and this cake is a basic material for producing glass fiber products for various applications.

For example, as in the case of producing glass fibers for fiber reinforced plastics, in order to produce glass fibers having a predetermined thickness, raw yarns are respectively drawn from an appropriate number of cakes, and these are combined into one. It is wound on one roving. That is, the number of cakes for simultaneously supplying the raw yarn to one roving is determined depending on how many raw yarns the required yarn thickness corresponds to. In such a roving process, a required number of cakes are arranged for each roving on a cake placing shelf called a creel shelf, and the raw yarn is forcibly wound from each cake by a winder.

The yarn on the outer surface side of the cake may be discolored due to heat treatment in the manufacturing process. The yarn wound on the roving is supplied from the inner surface of the cake, so if you do not want to supply the discolored yarn to the roving, remove the old cake when the remaining yarn amount reaches a certain value. It is necessary to replace it with a new cake and tie the old and new threads together. In addition, even if you do not have to consider the discoloration of the thread,
When the yarn is gone, the next cake must be set in place on the creel shelf without delay and the old and new yarn must be tied. The cake handling work in the roving process, such as the replacement of old and new cakes and the setting of new cakes, has been performed manually by a worker who monitors the process.

[Problems to be Solved by the Invention]

In the roving step, for example, several tens of cakes are often set for one roving, and the creel shelf usually has many such thread rows. Therefore, one worker has a large number of cakes, and there is a problem that the worker who monitors the process and sets / exchanges the cake is very tired.

The present invention has been made in order to solve such a problem, and automates the handling of cakes in the above-mentioned roving process, and can replace the old and new cakes and the old and new original yarns without changing the cake. The purpose is to provide a device.

[Means for Solving the Problems]

The cake exchanging device of the present invention is a cake exchanging device for setting or exchanging the cakes in a roving process of arranging a large number of cakes made of rolled yarns on a creel shelf and rewinding the yarns from each cake into rovings. And a pair of setting devices for moving the cake along the creel shelves, a pair of setting devices for moving the cake into and out of the creel shelves provided on the moving device, and having a retractable arm. And a yarn splicing device that splices the original yarns of the two cakes that are exchanged in 1.

[Action]

One of the setting devices provided in the moving device holds the new cake, and one end of the original yarn of the new cake is set in the yarn splicing device. If the old cake set on the creel shelf needs to be replaced as the roving process progresses, the moving device moves to the position of the old cake. Here, the other setting device takes out the old cake from a predetermined position on the creel shelf, and the taken-out yarn of the old cake is connected to the yarn of the new cake by a yarn joining device. Then, the moving device is moved, one setting device is positioned at a predetermined position of the empty creel shelf, and the new cake is set at the predetermined position.

In this embodiment, in order to prevent the discolored yarn on the outer surface side of the cake 2 from entering the product, the yarn is advanced from the inner surface side of the cake 2 to some extent, and the weight of the cake becomes 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, may be determined in consideration of the yield of the material as long as there is little risk of sending the discolored yarn to the roving.

The weight of each cake 2 in the creel rack 1 is measured by a load cell, and the measured data is sent to a control means such as a personal computer (not shown) via the ground control panel 4. Then, the ground control panel 4 is adapted to determine cake replacement and yarn breakage based on these weight data. That is, when the weight is less than the set value, it is determined that the replacement is required, and when the weight of the cake is stopped for a certain period of time, it is determined that the yarn is cut and the yarn is not delivered. Then, the ground control panel 4 is configured to control the cake changing device 6 on the basis of such a judgment so as to perform a constant cake change or to cope with an abnormal situation such as a yarn break.

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