DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for tapping a yarn end portion of glass fiber from the inside of a glass fiber cake.

[0002]

2. Description of the Related Art Usually, glass fiber is produced by winding a tubular tube serving as a core made of paper, plastic, or the like in a spinning process and then extracting the tube. Simply called cake.). Therefore, roving (R
OV), chopped strands (CS), chopped strand mats (CM), etc., in order to remove processed parts (binder dust) of the sizing agent from the inside of the cake once wound, that is, there is a quality problem. It is necessary to perform an operation called “opening” for finding and aligning the yarn ends after removing the portion.

[0003] For example, in the conventional pouring operation, an operator puts a cake on a special table, rubs the inner surface of the cake with bare hands, picks up an appropriate amount of thread clumps, and pulls it out of the cake. Has become. In this work, when a certain amount of thread bundles are pulled out, a plurality of thread bundles wound in the shape of a cake begin to align, and thereafter, the tangled and hardened part is cut off, and the multiple thread bundles are cut from the same part. Adjustment is made so that they can be taken out together (a state in which a plurality of yarns are shifted by less than one turn on the inner surface of the cake), and the yarn bundles are tied together so that the yarn bundles do not come apart, and the operation is completed.

[0004]

There are a number of problems with such a conventional tapping operation. For example, when the number of cakes to be worked on is large, physical labor becomes extremely hard, glass fibers are entangled in hands and glass dust is scattered, so it was not very good in terms of work environment . Also, in terms of work content, there is a difference in the removal amount of the migration part depending on the operator, and furthermore, skill is required to align the yarn ends so that a plurality of yarn bundles can be uniformly unwound from almost the same part. There was a variation in the volume due to individual differences among the participants.

[0005] The present invention has been made in view of such a conventional problem, and is intended to make such a glass fiber cake pouring operation more speedy and more reliable, and to be able to quantify the amount of pouring without any person.

FIG. 2 is a front view as viewed from a -2 direction.

The present device can be broadly divided into a thread bundle pull-out portion and a cake holding portion. The thread bundle pull-out portion includes a rod 1 with a hook, a thread bundle pull-out air nozzle 2, and a thread bundle amount detection area. A sensor 3 is provided. Rod 1
Descends obliquely at a predetermined angle with respect to the lumen of the glass fiber cake 4, and has a hook 5 as shown in FIG.
Then, the thread on the inner surface of the cake 4 is hooked by a predetermined amount, and the thread lump at the migration portion is pulled out through the air nozzle 2 and reciprocated to return to the original position. As the air nozzle 2, various known air nozzles, for example, Wonder Gun (trademark) manufactured by Osawa & Co., can be used, but it is desirable that the air discharge amount can be controlled stepwise. The area sensor 3 detects the amount of the glass fiber yarn bundle 4a at the outlet of the air nozzle 2 and controls the amount of air discharged from the air nozzle 2, and may employ a known linear image sensor, optical sensor, or the like.

The cake holding portion is provided with a cake holder 8 that moves up and down to fix and open the cake 4 at a position on a roller conveyor 7 for placing and transporting the tray 6 on which the cake 4 is placed. , Yarn end presser weight moving device 9, yarn end bundling device 10, yarn end cutting device 1
1 and a peeling assist ring 12 on the opposite side of the cake 4. In the figure, reference numeral 13 denotes a tray positioning device for positioning the tray 6, and reference numeral 14 denotes a moving unit for mounting and moving each device of the cake holding portion.

As shown in FIG. 4, the tray 6 is provided with an angle-shaped weight holder 16 on which a yarn end holding weight 15 made of a magnetic material is placed on the side where the yarn bundle is drawn, and the yarn end holding weight moves. The device 9 is configured to move up and down by attracting the yarn end weight 15 by the electromagnet 17 at the tip. The yarn end bundling device 10 is for narrowing the glass fiber yarn bundle 4a spread and drawn out from the cake 4 to the center position of the cake 4, and as shown in FIG. It is composed of a pair of bar members 18, 18 that can be vertically rotated in a plane perpendicular to the direction in which the yarn bundle is pulled out (left-right direction in FIG. 1). Thread end cutting device 11
Is provided with a cutter 19 for cutting the glass fiber yarn bundle 4a drawn out of the cake 4, and is used, for example, to cut off a tangled portion (migration portion) and a portion where the yarn is aligned.

The peeling assist ring 12 is a hollow cylindrical member having a diameter larger than that of the air nozzle 2 and smaller than the inner diameter of the cake 4.
1 in a horizontal and coaxial manner and in parallel with the inner surface of the cake 2.
In the left-right direction to assist the peeling of the yarn. In addition, as the peeling assist ring 12, not only a hollow cylindrical member but also a pair of flat or half-tubular members can be used.

Next, the operation of the apparatus of this embodiment will be described with reference to a single fiber diameter of 1.
0μ, 1,000 glass strands bundled into 10
A description will be given of an example in which the glass fiber cake 4 is divided into 0 bundles, and a total of 10 glass fiber yarns are wound into a tube and the glass fiber cake 4 is spouted. Although various numerical values will be described, these numerical values and the contents of the description are provided to facilitate understanding of the operation of the present embodiment, and the present invention is limited by these numerical values and the contents of the corresponding description. Not done. Although illustration is omitted, the device of the present embodiment is
A sensor and the like for positioning the roller conveyor 7 and the tray 6 are provided.

First, the apparatus of the present embodiment is set to the origin state shown in FIG. 5, the cake 4 is placed on a dedicated tray 6, conveyed to the front of the apparatus of the present embodiment by a roller conveyor 7, and the tray is detected by a sensor (not shown). The position of the tray 6 is detected and aligned, and the entire tray 6 is fixed by the tray alignment device 13.

Next, the yarn end holding weight moving device 9 is lowered, and the yarn end holding weight 15 on the weight holder 16 is moved to the electromagnet 17.
The cake 4 is fixed by lowering the cake holder 8 at the same time by attracting and lifting it with the magnetic force (FIG. 6). After the completion of the fixing operation, each device of the cake holding portion including the cake 4 is advanced by the moving unit 14 toward the air nozzle 2 and set so that the air nozzle 2 is inserted into the center of the cake 4 (FIG. 7).

Then, the air nozzle 2 is tilted by about 30 degrees, and the rod 1 is extended so as to come into contact with the inner surface of the cake 4 through the center of the air nozzle (FIG. 8). At this time, if the contact pressure on the inner surface of the cake 4 by the hook 5 at the tip of the rod 1 is too high, the inner surface of the cake 4 will be damaged. The air nozzle used was Wonder Gun (trademark) J-38 manufactured by Osawa & Company having an inner diameter of 38 mm. When the hook 5 at the tip of the rod 1 comes into contact with the inner surface of the cake 4, the hook 5 hooks the yarn bundle. At this time, the weight of the thread to be removed changes depending on the amount (depth) of the hooking claw 5 biting into the inner surface of the cake 4, and in the present apparatus, the amount of dumping waste (migration portion) is set to 100 g, and The bite amount d was about 1 mm (see FIG. 3).

After the hook claw 5 holds the thread bundle, the rod 1 is contracted and the hook claw 5 is pulled out again through the air nozzle 2. (FIG. 9). Here, the distance for pulling the rod 1 is preferably equal to or more than の of the circumference of the cake 4. In the present embodiment, this distance was 900 mm.

The lump 4b of the dumping dust is
The glass fiber yarn bundle 4a passes through the air nozzle 2
When it is pulled out to the rod 1 side from
The compressed air is supplied from an air source (not shown) by returning the air nozzle 2 to a horizontal position (FIG. 10). In this embodiment, the supply air pressure is between 1 kg / cm2 and 5 kg / cm2,
The pressure is controlled according to the content detected by the area sensor 3.
That is, when a large lump of dust 4b is generated in the vicinity of the outlet of the air nozzle 2, the maximum pressure is supplied, and when the lump of dust 4b is pushed out by air and becomes close to a state where the yarn bundles 4a of glass fibers are aligned. Supply the minimum pressure to align the yarn. By switching the pressure of the compressed air from the maximum to the minimum, it is possible to use a single air nozzle 2 to both pull out the first tangled portion and align a plurality of yarn ends.

At the same flow rate, the yarn bundle with a small resistance, that is, the yarn bundle with a fast circulation is skipped first, and the yarn bundle with a large circulation delay is left behind at the same flow rate, and this is repeated quickly. With the passage of time, the peeling positions of the plurality of yarn bundles are aligned on the same circumference. Accordingly, the state of the yarn blown from the discharge end of the air nozzle 2 is changed from the large lump state (1) picked up by the hooking claws 5 to the medium lump state (2) tangled due to being hooked in the large lump state. , And 10 glass fiber threads are a few
A state (3) is obtained in which the circumference is shifted, and furthermore, all the yarns of the yarn bundle 4a being pulled out are pulled out on the inner surface of the cake 4 with a deviation of a pulling position of less than one round (4).
Therefore, the air pressure supplied to the air nozzle 2 is also switched in accordance with this. Of course, if the thread does not reach the state (4) in one operation, the air pressure supplied to the air nozzle 2 is automatically switched by discriminating the amount of the thread with the area sensor 3 and the above-mentioned operation is performed. The states (2) to (3) are repeated.

If the above conditions (2) and (3) continue for a certain period of time or more, the peeling assist ring 12 is moved into the cake 4 from the opposite direction to the rod 1 and the air nozzle 2. It is inserted and repeatedly moved back and forth to help peel off the yarn that is peeled off from the inner surface of the cake 4 and is being sucked into the air nozzle 2 (FIGS. 11 and 12).

When the state of the yarn coming out of the air nozzle 2 becomes uniform, the moving unit 14 including the cake 4 is moved backward in a direction away from the air nozzle 2 (FIG. 13). Next, as shown in FIGS. 14 and 15, processing of the yarn end is performed. First, the pair of bar members 18, 18 of the yarn end concentrating device 10 are rotated downward, and are brought to the center from both sides of the cake 4, and the yarn coming out of the cake 4 is collected at the center of the cake 4, The end holding weight moving device 9 is lowered, and the yarn is held between the yarn end holding weight 15 and the weight holder 16 attracted to the electromagnet 17 so as to fix the yarn so that the yarn ends do not fall apart. If the yarn is pulled out from the air nozzle 2 with the minimum pressure during the yarn end bundling operation, tension can be applied to the yarn, and the yarn end processing operation is stabilized. Thereafter, the yarn fixed by the cutter 19 of the yarn end cutting device 11 is cut to complete the reeling (FIG. 16), and the cake 4 is sent out by the roller conveyor 7 with the cake 4 placed on the tray 6 to complete a series of operations. In addition, since the waste (migration part) of the glass fiber after the ejection is blown off to a certain place by air, if a waste case is installed in that place, the worker can easily clear the waste.

[0024]

As described above, the glass fiber cake pouring device according to the present invention is as described above. (1) By automating the manual pouring operation which has conventionally been performed manually, labor saving can be achieved. ) Since a certain amount of yarn is pulled out by the hook, the variation in the removal amount of the migration portion is reduced, the quality in the next process is stabilized, and the yield is improved. (3) A plurality of yarn bundles are aligned from almost the same portion. There are many effects that the work that required considerable skill of finding and aligning the yarn ends so that it can be pulled out can be automatically performed.

In the glass fiber cake pouring device according to the third aspect of the present invention, when the glass fibers in the cake cannot be peeled off satisfactorily only by the force of air, the peeling aid is inserted between the inner surface of the cake and the air nozzle and moved. Since the separation of the glass fiber in the cake can be assisted, there is an effect that the migration portion can be surely removed.
