Description

Polyester fiber ball manufacturing method and apparatus therefor {Polyester Fiberball Process and Machine Therefor}

The present invention is directed to a method and apparatus for making polyester staple fibers into ball-shaped chemical fibers by repeatedly impinging the tip with tumbling in a container.

The processing of polyester staple fibers into ball-shaped fiber (fiberfill or fiberball) has the advantage of excellent cushioning and resilience and long lasting. Therefore, it is used as a filling material for pillows, blankets or stuffed toys, and lining for clothes.

A method and apparatus for making polyester staple fibers into ball-shaped cotton fibers are disclosed in Korean Patent Publication Nos. 91-2511 and 4,783,364. In the context of these inventions, the polyester fibers are treated with a silicone lubricant or mixed with the binder fibers treated with the lubricant, or heat-shrinked in the mold using polyester staple fibers that are spirally corrugated by covering or binding the binder fibers. It is to make a fiber ball of a certain size and cut it to a certain length, and another is to make a fiber ball by tumbling which hits the container wall by using the air generated by the rotational force of the blades installed in the container. will be.

However, the fiber ball obtained by the conventional method as described above has a problem that the size of the ball is not constant and takes a lot of production time. In addition, there is a problem in having persistence in cushioning and resilience. In other words, the method of forming the wrinkles using the binder fibers should be cut every part of the wrinkled fibers in the form of balls from the spirally drawn fibers, and cushioning than the fiber balls obtained by tumbling because the binder is used There was a problem in weakness and resilience gradually weakened cushion and resilience.

In addition, the fiber balls obtained by tumbling polyester staple fibers on the container wall by the rotation of the blades in the container are not uniform in size and take a lot of time to manufacture, especially large and uneven in fiber balls of non-uniform distribution. In the case of the fiber ball obtained in the state was released after washing and tangled with adjacent fiber balls, the main cause of the loss of cushioning power and recovery.

It is an object of the present invention to provide a method and apparatus for uniformly forming the size distribution of fiber balls to enable the production of very simple and fast fiber balls and to maintain cushioning and resilience over a long period of time.

In order to achieve the above object, the present invention provides a method for obtaining a fiber ball by repeatedly tumbling the batted polyester staple fibers in a container, wherein a plurality of small tips having an acute angle formed at the end of the rotational direction are continuous on the circumferential surface. And the supplied polyester staple fiber between the installed cylinder and the wall of the casing in which the cylinder is installed, and repeatedly caught at the tip end while tumbling due to the collision between the tip and the airflow generated by the rotation of the cylinder. The present invention provides a manufacturing method in which fiber balls having an average size of 1 to 10 mm are obtained by entangled with gradually circular random groups.

As a manufacturing apparatus according to the above method, an acute angle is formed at the end of the blade in the direction of rotation. A cylinder in which several small tips are continuously arranged on the circumferential surface, a casing in which the cylinder is installed at the center and the inlet and the outlet are formed on both sides, and the other surface. A pair of feed belts for conveying the polyester staple fibers to the outlet, a pair of rollers for feeding the fibers conveyed from the feed belts to the inlet of the casing, and a circular shape as the cylinder rotates in the casing. It characterized by consisting of a pair of discharge belt for discharging the fiber balls entangled in a random single body to the outside through the outlet of the casing.

According to the configuration as described above, when the fiber staple fiber, which is already made on the other side by the carding machine, is fed into the casing by the supply belt and the roller, the fibers are continuously caught (while being caught) by the tips of the rotating cylinder. By tumbling, they are separated into small groups, and at the same time, they are randomly wound to obtain a large number of balls close to the circle.

Embodiments of the present invention will now be described with reference to the accompanying drawings.

First, a manufacturing apparatus is demonstrated. Figure 1 schematically shows the configuration of the manufacturing apparatus, 1, 1 'is a supply belt, 2, 2' is a roller, 3 is a cylinder, 4 is a casing, 5, 5 'is a discharge belt, 6 is The ball separator, 7,8 is a motor.

The supply belts 1 and 1 'are for supplying the polyester staple fibers sent after being burned in the other surface machine (not shown) installed on the right side of the manufacturing apparatus into the casing 4. The rollers 2 and 2 'are formed with irregularities on the outer surface, and serve to allow the fibers on the supply belts 1 and 1' to be supplied without slipping when they are supplied into the casing 4. The feed belts 1, 1 ′ and the rollers 2, 2 ′ are rotated by the motor 7.

The cylinder 3 makes contact with the faced polyester staple fibers as a key element in the present invention to make fiber balls. The cylinder 3 is installed in the casing 4, and a minimum space is formed with the inner wall of the casing 4 to enable tumbling. In other words, when a fiber ball having a size of 1 to 10 mm finally collides with the cylinder 3, it is sufficient to have a space where the fiber ball can immediately collide with the inner wall of the casing 4 and bounce back toward the cylinder 3 again. For example, the distance between the inner wall of the casing 4 and the cylinder 3 can be set at an interval of about 25 to 50 mm from the tip 9 of the outer surface of the cylinder 3.

As shown in Fig. 2, the cylinder 3 has a number of circumferential surfaces, for example, 406.4 mm in diameter of the cylinder 3, and when the length is 1,200 mm, about 680 tips 9 are successively erected at equal intervals. Are arranged. Each tip (9) The bottom surface is attached to the cylinder 3 in the cross-sectional shape as shown in FIG. As shown in Fig. 5, the tips 9 form a V-shaped blade on the front face (left) and have an acute angle on the front face.

FIG. 3 shows a case where the inclination of the tip 9 is continuously arranged at all intervals at equal intervals at about 20 ° from a horizontal or vertical line on the outer surface of the cylinder 3. When the tip 9 is inclined and arranged on the cylinder 3 surface, the demand of the tip 9 can be reduced.

FIG. 4 is an arrangement in which the rows of equal intervals are arranged vertically in a row in the horizontal direction without giving the inclination of the tip 9 on the outer surface of the cylinder 3, and the adjacent tips in the vertical direction (vertical direction) ( 9) are arranged to be offset from each other. Therefore, since the tips 9 arranged in the longitudinal direction are arranged in a zigzag, an effect similar to the arrangement of the tips 9 having the arrangement inclination can be obtained. The operation of this tip 9 will be described later. The cylinder 3 rotates by the motor 7.

The discharge belts 5, 5 'are for discharging the fiber made in the form of a ball by the cylinder 3 in the casing 4 to the left of FIG. The discharge belts 5, 5 ′ are rotated by the motor 8. At the outlet of the discharge belts 5, 5 ', a ball separator 6 is provided.

As shown in FIG. 6, the ball separating device 6 is installed at the end of the discharge belt 5, 5 ′, and has a disk 12 made of a saw blade having a positive upper surface in the discharge direction. A plurality of coaxially installed and to enable high-speed rotation by the motor (8) is to disperse the aggregated fiber balls discharged through the discharge belt (5, 5 ') in a coarse state. A disk 12 made of saw blades is actually a type in which a number of disks 12 are continuously inserted into and coupled to a pipe in the axial direction with a slight distance from each other.

Reference numeral 10 is a viewing window, and 11 and 11 'are reduction gears attached to the motor 7 and the motor 8, respectively.

A process and a manufacturing method of making the fiber ball by the manufacturing apparatus as described above will be described.

The fiber which is previously burned by the carding machine cannot be used unless it is polyester fiber and treated with silicone oil (polyester staple fiber). In other words, if the frictional force by the lubricating oil is not canceled, the circular ball cannot be obtained because the tip 9 is irregularly caught in the collision process with the tip 9 of the cylinder 3. This fiber can be 3 to 15 denier, and it is preferable to use about 3 denier, especially when used as a lining for filling clothes. 3denia should be made because when filling with the lining of clothes, unlike when filling bedding or stuffed toys, the clothes should be made of small balls to achieve good weight and light weight. Moreover, although the fiber length is 32 mm normally, the above fibers can be used for 15-100 mm. However, the longer the fiber length is, the easier it is to form a fiber ball while curling, while the diameter of the ball is larger, its use is limited.

The burned fiber is fed toward the casing 4 by the feed belts 1, 1 ', and the rollers 2, 2' push the fiber toward the outer surface of the cylinder 3. The fibers are tumbling between the rotating cylinder 3 and the adjacent inner wall of the casing 4 by an airflow generated by the rotation of the cylinder 3 and a collision with the tip 9, and gradually into a smaller and more dense fiber ball. Is made. The action of the tip 9, which provides its main cause, is shown in FIG.

That is, the fibers are repeatedly caught at the tip 9 at the point where the front surface (left vertical surface) of FIG. 5 meets the slopes and gradually entangled into circular random groups to obtain a fiber ball having an average size of 1 to 10 mm. In other words, each time the ball is caught by the tip (9), the outer surface is evenly rounded and small. The requirements for determining the size of the fiber balls also vary depending on how many times the apparatus body is subjected to it. However, when only one manufacturing apparatus passes through once, its diameter varies depending on the rotational speed of the cylinder 3. For example, in the case of using a polyester staple fiber having a fiber length of 32 mm, the cylinder 3 rotates when the diameter (inner diameter) of the cylinder 3 is 406.4 mm and the distance between the tip 9 and the blade 9 is 36 mm. At a speed of 1,300 rpm, a ball of at least 3 mm is obtained, and at 860 rpm, a ball of at least 5 mm is obtained.

The fiber balls thus produced are discharged toward the ball separating device 6 by the discharge belts 5 and 5 'while accumulating into the space of the casing 4 formed on the left side of the cylinder 3, and in the ball separating device 6 In the process of discharging the discharge belt (5, 5 '), the aggregated fiber balls are scattered to each group to play a role. The fiber balls which have passed through the ball separator 6 remain separated from each other naturally.

7 to 9 are photographs taken by gradually expanding the fiber balls obtained by the present invention. FIG. 10 is a photograph showing the fiber balls obtained by Korean Patent Publication Nos. 91-2511 and 4,783,364 mentioned in the prior art for comparison with the present invention. When comparing the conventional fiber ball and the fiber ball obtained by the present invention, it can be seen that the conventional fiber balls are partially agglomerated, not uniform in size, and have a large difference in density between the individual fibers. However, in the case of the present invention, on the contrary, it is not agglomerated, the size is constant, and it can be seen that there is almost no density difference between the groups.

The present invention configured as described above can produce a very simple and fast fiber ball, and the size distribution of the fiber ball can be made uniform. As a result, the resilience and cushioning ability is excellent over a period of time, so that even if used for a long time in clothing, stuffed toys, bedding, the internal fiber surface does not lose its volume and cushioning power. In addition, even after washing in the washing machine does not loosen, and maintains the cushioning and recovery.
