Description

[Detailed description of the invention] This invention relates to a method of manufacturing a fryer.

The flyer of a roving frame has a spindle in the center for guiding the bobbin, the upper part is supported by a support rail, and the flyer is rotatably driven by a drive mechanism within the rail, and the flyer is of the type that has a spindle for guiding the bobbin in the center, and the flyer has a spindle on the bobbin rail. Supported at the tip of the spindle,
There is a type of rotation that is transmitted by it,
Due to the recent trends toward higher speeds, larger packages, and even automation, the former type has become mainstream. In other words, in the former upper support type, the flyer is completely independent from the bobbin rail, making it easy to rotate at high speeds and increase the size of the flyer. It is easy to do tamage or simple tamage. Nowadays, as fryers are becoming faster and faster, the effects of air and centrifugal force are becoming more of an issue. 17th
As shown in the figure, in the conventional general flyer, the roving comes out from the hole 22 of the neck part 21 and is wound once, and then the thread is wound around the leg part 23.
Since the roving is passed through the groove 24 and reaches the presser 25 below, it is first subjected to air resistance at the neck portion 21, which tends to cause fuzzing, and also tends to cause the roving to break due to the centrifugal force of the roving. Furthermore, as shown in FIG. 18, in the leg portion 23, since the longitudinal openings of the grooves 24 face the direction of rotation of the flyer, turbulent flow occurs within the grooves 24, causing fuzz on the passing rovings and , attracts fluff into the inside and surface of the groove 24. When a certain amount of this fluff accumulates, it is carried to the roving, and this process is repeated. Due to this increase in speed, the roving is exposed to the great influence of air resistance and centrifugal force, which causes the disadvantageous situation of deteriorating the quality of the winding roving and increasing the rate of roving breakage. There is.

The present invention aims to manufacture an upper support type flyer using a special method and achieve high speed, with the aim of not deteriorating the quality of the wound roving and not increasing the roving breakage rate. It is something.

The basic idea of the present invention is that when the roving passes through the flyer, it passes through an enclosed vibrator so as not to be exposed to air resistance. Next, the neck part on which the fryer is supported should be equipped with a rotational drive mechanism such as a gear, so it should be made separate from both legs due to the special material and processing required. Furthermore, the central spindle is also constructed separately from both legs in order to obtain a smooth surface for guiding the bobbin. In addition, since the legs are the main parts of the flyer, they are made of aluminum alloy to reduce weight to suit higher speeds and to facilitate molding and processing. Based on this idea,
In the present invention, a metal thread pipe is formed which is bent from the neck part of the ear to follow one leg, and an iron arbor is formed through which the upper part of the thread pipe passes and into which the bent part fits. A fitting hole is formed in this arbor into which a spindle that should be located in the center of the flyer is fitted, and with the thread guide tube inserted into this arbor, the arbor is placed in the flyer neck part within the flyer formwork. At the same time, an iron plug is applied to the fitting hole, and the thread pipe is fixed at one end to absorb expansion, and aluminum alloy is poured into the flyer formwork. After cooling, remove the iron plug and install the spindle and presser. This process was used to manufacture hula and ears.

An embodiment embodying the present invention will be described below with reference to the drawings.

Place a stainless steel or light alloy vibrator from the neck of the flyer along one leg. By bending and forming it in this manner, the thread guide tube 1 is formed. The inner surface of the yarn guide tube 1 is completely surrounded and is made of a surface treated or processed material for smooth passage of the rovings. The insertion hole 2a into which the upper part of the thread guide tube 1 is inserted, and the insertion hole 2a
The arbor 2 has a large-diameter fitting hole 2b formed in communication with the arbor 2, and a fitting groove 2c provided on the side so as to be able to fit into the bent portion 1a of the thread guide tube 1. , the thread guide tube 1 is fitted into the fitting groove 2c so that the bent portion 1a thereof fits into the fitting groove 2c. The arbor 2 is made of iron because it supports the flyer itself on a support rail (not shown) and is a place to which a drive gear is attached. Next, the fitting groove 2c is formed on one side of the cylindrical portion having a diameter smaller than that of the fitting hole 2b.
The fitting hole 2b is closed by an iron plug 3 having a protrusion 3a that can be fitted into the fitting hole 2b, and the spindle 11, which should be located at the center of the fryer, is to be fitted and fixed therein. As shown in Figs. 4 and 5, the iron plug 3 has its protrusion 3a.
is fixed to the rear par 2 by fitting into the fitting groove 2c, and there is a gap δ (0.1 to 0.2 mm) between it and the fitting hole 2b to prevent the aluminum alloy from entering. It is provided. On the other hand, as shown in FIG. 6, a presser attachment member 4 made of stainless steel vibrator is fitted to the lower end of the fiber pipe 1, and a presser (not shown) is fitted into a fitting groove 4a formed at the upper end of one side. A regulating member 5 for regulating the rotation angle is fitted.

Next, as shown by chain lines in FIG. 4, both legs 6 of the flyer,
7 and a neck part 8 supporting the lower part of the arbor 2, in a mold 9, the arbor 2 is located in the neck part 8, and the thread guide tube 1 is located in the center of one leg part 6. Deploy.

When setting in the formwork 9, fix the lower end of the filament tube 1,
The upper end is fixed via a spring 10 fitted into the arbor 2 so that it can expand and contract in the vertical direction. In this state, molten aluminum alloy is poured into the formwork 9. When pouring molten metal, the guide tube 1 expands due to thermal expansion, so if the upper and lower ends are fixed, the guide tube 1 will bend due to thermal expansion and will not stay in the specified position, and the guide tube 1 will be made of aluminum alloy. There is sleet that is exposed to the outside. However, in this embodiment, since the upper end is fixed by the spring 10, the elongation due to thermal expansion is absorbed by the spring 10, and the casting can be carried out in the specified position without causing the above-mentioned problems. It will be done. By pouring the molten metal, the lower end of the arbor 2 and the thread guide tube 1 are covered, and both the presser mounting member 4 and the regulating member 5 fitted in the thread guide tube 1 are covered with their upper parts as shown in FIG. is cast into the aluminum alloy forming one leg 6. After cooling, the formwork 9 is removed, and the iron plug 3 is removed from the arbor 2. Then, the leg 7 without the thread pipe 1 is perforated, and a female thread 7b is formed at the tip of the formed hollow part 7a. engraved with screws.

After performing surface treatments such as strain relief, tufting, and painting, the base end of a separately manufactured spindle 11 is fitted and fixed into the fitting hole 2b of the arbor 2. Since the spindle 11 fits into the bobbin and guides its lifting and lowering, the spindle 11 is machined and treated to have an appropriate surface condition, and is preferably made of iron.

This spindle 11? If the spindle 11 is cast by fitting into the arbor 2 from the beginning, the heat during casting may cause the plating on the spindle 11 to peel off or discolor. However, in the present invention, the spindle 11 is fitted and fixed to the arbor 2 last, so there is no such problem. In order to prevent air turbulence from occurring behind the legs 6, 7 during high-speed rotation of this flyer, the cross-sectional shape of the legs 6, 7 changes continuously as shown in Figures 10 to 15. It is formed like this.

However, since it is cast, even the shape described above can be easily manufactured without the need for post-processing, and it is also lightweight. This fryer is used by attaching a presser 12 (shown by a chain line in FIG. 7) to a presser attachment member 4 provided at the tip of one leg 6, and is stored in the hollow portion 7a of the other leg 7. By changing the weight of the balance weight, the left and right balance can be easily adjusted.

Specifically, after storing the balance weight, a plug is screwed into the female threaded portion 7b to seal it. In the embodiment described above, the guide tube 1 was made of stainless steel or light alloy.
The thread guide tube 1 needs to be free from rust and have a smooth surface.

Since the flyer body is molded from an aluminum alloy, heat treatment is essential to increase its strength, and water quenching is required, so the thread guide tube 1 through which the roving threads pass must be made so that - does not occur. In addition to having a vibrator-like shape,
It is difficult to treat or process the inner surface. Taking these things into consideration, it is optimal for the thread guide tube 1 to be made of stainless steel. In this embodiment, the presser attachment member 4 made of stainless steel vibrator is fitted to the lower end of the thread guide tube 1.
As shown in the figure, the lower end of the thread guide tube 1 may be covered with aluminum alloy and the presser 12 may be attached to the outer periphery thereof.

The support part 13 of the presser 12 has a fitting hole 12a into which the lower end of the leg part 6 is to be fitted, an accommodating part 13b communicating with the fitting hole 13a and opening upward, and the accommodating part 13b.
A bolt hole 13c that opens outward on the opposite side to the insertion hole 13a is formed, and the nut 14 accommodated in the accommodation portion 13b is received by the regulating member 5 cast into the lower end of the leg portion 6. In this state, the presser 12 is rotatably attached to the lower end of the leg portion 6 by threading the bolt 16 inserted through the bolt hole 13c via the spring washer 15. As described above, in the method of the present invention, the flyer neck part is made of an iron arbor, the thread guide tube fitted into the neck part is shaped to follow one of the legs, and after both legs are molded from aluminum alloy, the spindle is fitted into the arbor. According to this method, the outer shape is simple, the number of processed parts of the flyer after molding is small, and processing is easy.

According to the flyer manufactured by the method of the present invention, the arbor is firmly supported on the support rail, and the roving is hardly affected by air resistance or centrifugal force, so high quality roving can be cut at a high rate. Can be wound at high speed with little turbulence.
