Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention prevents the package from collapsing during transportation when the package is made by winding polyester, polyamide, etc. yarn onto a drum and is unwound for use. The present invention also relates to a packaging method for a package that maintains good unwinding properties.

[Prior Art] A method of packaging a package in which yarn of polyester, polyamide, etc. is wound on a drum is to keep the side surfaces of the yarn layer wound on the drum, so-called both end surfaces of the package, out of contact with the packaging support plate, (hereinafter referred to as "drum support packaging"), and packaging methods in which both ends of the package are in contact with a packaging support plate and supported by the package ends (hereinafter referred to as "thread layer support packaging"). > is generally known.

This will be explained in detail using figures.

FIGS. 2 and 3 are cross-sectional views showing examples of conventional drum packing and yarn layer packing methods, respectively.

In FIGS. 2 and 3, 1 is the package, 1A is the end surface of the package on the unrolled side, 1B is the end surface of the package on the non-unwound side, and 2
3 indicates a drum (paper tube), 3 indicates a packaging support plate with a plug made of corrugated paper or plywood, 4 indicates a plug, and 5 indicates a packaging support plate with a drum insertion hole.Usually, the unit shown in Figures 2 and 3 is The actual shipping form is 2 to 20 pieces arranged on one plane and stacked in 2 to 10 stages.

By the way, in recent years, with the aim of cost reduction and labor saving, large packaging of 10K9 or more has been adopted in yarn production, high-speed warping of 1000 m/m+n or more in yarn processing,
High-speed 7lO machining is becoming common.

In the case of such large packaging and high-speed unwinding, the diameter of the package becomes large in the conventional drum-carrying packaging method, so there is a problem that the yarn layer collapses due to vibration during transportation. In other words, in Figure 2, the lower package end face IB is floating in the air, so
The yarn layer collapses due to vibration.

On the other hand, in packaging with yarn layers, the package end face is damaged (unraveling failure becomes noticeable. In other words, as shown in Fig. 3,
The usual method is to provide a gap between the package end faces 1A, 1B and the packaging support plate 5 in consideration of workability during packaging, but since the package is prone to sway and has a thread layer. Since the unwinding direction is always the end face of the package, which includes slight deviations in the yarn layer due to horizontal shaking, the yarn layer (@
The surface will collapse and loops will come off when unraveling.

In addition, in the method shown in FIG. 3, there is a method of hanging a bag over the package 1 to protect it, but this is not a fundamental countermeasure because the weight of the package makes a large contribution to the slight deviation of the thread layer.

Neither method can be said to be a packaging method suitable for large packaging and high-speed unpacking.

[Problems to be Solved by the Invention] A method for solving the problems of the present invention's collapsing threads during transportation of large packages and poor unraveling during high-speed unraveling has been intensively studied, and two problems have been solved at once. The present invention was achieved by discovering a packaging method that does the following.

[A Thousand Steps to Solve the Problem] The above-mentioned invention is based on the above-mentioned method, when packaging a package wound with yarn, the end surface of the package on the unwinding side does not come into contact with the packing support plate, and the end surface of the package on the non-unwinding side is This can be achieved by a method of packaging a package, which is characterized in that it is brought into contact with a packaging support plate and is packed with the ununrolled end of the package facing down.

The present invention will be explained in more detail below. FIG. 1 is a sectional view showing an example of the packing method of the present invention.

Here, 1 is the package, 2 is the drum (paper tube), and 3
1 shows a packaging support plate with a plug made of corrugated paper or plywood, 4 a plug, and 5 a packaging support plate with a drum insertion hole. Usually, the actual shipping form is 2 to 20 units shown in FIG. 1 arranged on one plane and stacked in 2 to 10 stages.

The first point of the present invention is that the package end face I on the unrolling side
The purpose is to make A non-contact with the packing support plate 3 with a plug. In other words, slight deviations of the thread due to sagging during unwinding, loose loops, and lateral vibrations during transportation are caused by the thread falling toward the unwinding side due to the pulling force during unwinding. Therefore, if the influence of abrasion is avoided on the end face of the package on the unwinding side, there will be no problem with the unwinding performance.

Next, the second point of the present invention is to pack the package with the non-unrolled side package end face 1B facing down, and to bring the non-unrolled side package end face 1B into contact with the packaging support plate 5 with the drum insertion hole 5. It's about supporting.

That is, since the collapse of the yarn layer during cargo handling during transportation is caused by vibration in the longitudinal direction, if only the lower package end face 1B is supported, the collapse of the yarn layer will not occur.

That is, in the method of the present invention, the lower package end face 1B
is supported in contact with the packaging support plate 5 with a drum insertion hole, and the threads do not collapse during transportation or cargo handling, and the upper package surface 1A is not in contact with the packaging support plate 3. Therefore, by making the package end face 1A side the unwinding side package end face, no slippage or loop slipping occurs during high-speed unwinding. Unraveling defects due to slight deviations of the A3 yarn layer are not a major problem during conventional low-speed unwinding, but they become particularly noticeable when the unwinding speed becomes high, close to 1000 m/min.

Although the package end face 1B on the lower side of Naa3 is set to the non-unrolling side, the influence of horizontal shaking during transportation is
In order to avoid this problem, it is preferable to use the method 6 in which the plug 1 is inserted and fixed inside the drum 2 as shown in Fig. 1, and the present invention is even more effective if the end face of the package is protected with a foamed polyethylene film or the like. becomes.

Further, the present invention can be applied to polyester, polyamide, and other synthetic fibers wound onto a drum.

[Example] The present invention will be specifically described below with reference to Examples.

EXAMPLE A polyester drawn yarn of 75 denier 36 filament 1 to 1, which was spun by a conventional method and then subjected to drawing heat treatment without being unwound, was wound in 101<9 turns. The winding width of the package is 14°, and the package diameter is 320° when rolled with 10 kg.

Next, four rolled up packages, two horizontally and two vertically, are packed into one case using the methods shown in Figures 1 (invention), 2 and 3, and after transportation, they are unpacked and transported at a speed of 1200 m/min. It was unraveled.

The method shown in Table 1 causes the package to collapse, while the method shown in Figure 3 causes the package to collapse.
Loop slippage during unwinding becomes a problem. On the other hand, in the method of the present invention (FIG. 1), neither package breakage nor unraveling ribs were removed, and the results were good.

[Effects of the Invention] According to the present invention, when packaging a package containing wound yarn, the end face of the pack on the unwinding side does not come into contact with the packaging support plate, so even during high-speed unwinding, the end face of the pack is not in contact with the packaging support plate. It is possible to obtain good unwinding performance without being affected by slight yarn layer displacement due to lateral shaking, and the package is packed with the end surface of the package on the non-unrolling side facing down. Since it is supported in contact with the packaging support plate, it is possible to eliminate thread sluices I0 during transportation and cargo handling.
