Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretch or cross-spiral type collective package in which a film is wound around a yarn package or a wound body which is stacked in multiple stages for packaging.

[0002]

2. Description of the Related Art Recently, there has been an increase in stretch packaging (cross spiral type) for the purpose of preventing dust from adhering and providing rigidity by winding a plastic film around a product.

A wound body, which is generally a yarn winding product wound on a bobbin (paper tube), has a polygonal, particularly quadrangular partition plate or pad as described in Japanese Patent Publication No. 59-34606. It is packed in a multi-layered structure with the items in between.

When stretch-packing a multi-stage laminate having such a shape, a conventional stretch-packing machine rotates a multi-stage laminate of wound yarns formed on a turntable and a film installed on the side of the turntable. The film is wound around the laminated wound body in a cross shape by moving the carriage in the vertical direction at a constant speed while stretching and carrying out stretch packing.

However, in such a method, when the film is wound around the laminated wound body in a slous shape, the film carriage moves up at a constant speed, so that the film 5 is placed on the side of the laminated wound body p as shown in FIG. A film edge (side edge) 5a passing between the partition plates 4 when passing a side (corner portion)
Has a problem of contacting the wound yarn p and damaging the wound yarn p.

[0006]

SUMMARY OF THE INVENTION The present invention solves the conventional problems described above and provides a package in which the film does not come into contact with the wound yarn body.

[0007]

That is, according to the present invention, a yarn winding thread body is laminated in multiple rows and multiple stages on a pallet with a partition plate interposed therebetween, and then the outer surface of the laminated body is equal to or more than the step interval. A rectangular column-shaped collective package formed by winding a wide resin film in a cross shape and covering the side edge of the rolled film at a corner (corner) of a partition plate which is a side of the package. It is a collective package of thread wound bodies characterized by being hung on the corners.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. In the figure, 2 is a rectangular pallet, on which a laminated body 3 of wound bodies stacked in multiple stages via a quadrangular partition plate 4 is formed. The periphery thereof is wound in a cross shape with a polyethylene resin film 5 and fixed to a rectangular parallelepiped as a whole to form a package 1.
The film 5 on which the laminated body 3 is wound has at least the edge of the upper part (the film edge of the innermost layer) 5a.
Hangs on the corner 4a of the partition plate 4 which separates and supports the wound body,
The corners 4a overlap each other.

For this reason, the film edge 5a wound between the partition plates 4 is not caught at the corner 3a of the laminated body (or the package), so that the film 5 overlaps the surface of the wound body. And the wound body is not damaged or damaged.

FIG. 2 is a side view of a packing device for making a packing body according to the present invention. Hereinafter, a method for forming the above-mentioned collective packing body of thread wound yarn bodies using this device will be described in detail.

In the figure, reference numeral 11 denotes a square turntable which is rotated by a drive mechanism (not shown) with a center point O as an axis at a predetermined speed. A control panel 14 is provided on a machine base 13 projecting through a base 12 at a lateral position of the turntable 11, and the film roll R is unrotatably fixed and rotated by driving a motor (not shown). The film carriage 15 is provided so as to be able to move up and down by a screw shaft 16. Reference numerals 17 and 18 are guide shafts, and 19 is a guide roller. The film carriage 15 may be moved up and down by using other known means such as a chain method.

In order to pack the wound body into the above-mentioned collective package by using such a device, as shown in FIG. The laminated wound body p is formed on the turntable 11 (directly formed on the turntable 11 or placed on another place may be placed), and then the film roll R fixed to the carriage 15 is attached. It is pulled out and its end is fixed by being sandwiched between the pallet 2 and the lowermost partition plate 4 or a fixed body such as a hook.

Next, the turntable 11 is rotated at a predetermined speed to wind the film 5 around the lower surface 4 of the laminated body 3 while applying a constant tension. At this time, the film edge 5a is wound on the partition plate 4 as follows. Corner (corner) 4
The position (raising speed) of the carriage 15 is synchronized with the rotation speed of the turntable 11 so that the film 5 and the winding body p do not come into contact with each other so that the film 15 and the winding p are brought into contact with each other.

That is, first, the position of the carriage 15 is fixed so that the lower end of the film roll R and the lower end of the lowermost partition plate 4 are aligned with each other. Then the upper film edge 5
After adjusting by turning the turntable 11 so that a is hooked on the corner portion 4a of the partition plate 4 in the middle portion, the turntable 11 is driven and wound around the first side surface (FIG. 3).

Next, the film moves to the second side surface. At this time, if the position of the carriage 15 (film roll R) is held as it is and the film is wound, the film edge 5a is moved to the partition plate 4 as shown in FIG. 4 (a). Come in contact with the side surface of the wound body. To avoid this, when winding the second side, see Fig. 4.
As shown in (b), the position of the carriage 15 is lowered while synchronizing the film edge 5a with the corner portion 4a of the partition plate 4 in synchronization with the rotation speed of the turntable 11 (the upper film edge 5a is the partition. It is preferable to hang it along the side surface of the plate 4).

Next, when winding the third to fourth side faces, the carriage 15 is wound while maintaining the position of this state,
One turn of the film is completed as shown in FIG.

When one turn of the film 5 is completed on the laminated body in this manner, the upper film edge 5a corresponds to the first side surface of the laminated body as shown in FIG. 4 (d). The carriage 15 is raised while being synchronized with the rotation speed of the turntable 11 so as to be hooked on the corner portion 4a of the film 5, and the film 5 is placed above the first turn (first roll)).
Wind up.

Next, the film winding on the second side is started. At this time, for the same reason as described above, the film edge 5a is positioned at the corner portion 4a of the partition plate 4 as shown in FIG. 4 (e). The position of the turntable 11 is lowered while being synchronized with the rotation speed of the turntable 11.

The third to fourth side surfaces are in this state (a position where the upper film edge 5a hangs on the side surface of the partition plate 4).
Then, the film 5 is fixed, and the second winding is completed.

Subsequent windings (from the third turn onward) are sequentially wound upward by the same operation as described above, and when the film 5 is completely wound up to the uppermost part to form the package 1 as shown in FIG. Return to the original position and complete the series of packing operations.

At the time of descending, it is not particularly necessary to wind the film so that the film edge is hung on the corner portion of the partition plate, and it may be just normal winding, and it is not always necessary to wind so as to overlap. The film winding when descending may be omitted.

The width of the film is usually larger than the height between the partition plates. In this case, it is not always necessary that the widths of the upper and lower film edges be applied to the partition plates during parallel winding. Or, in parallel or spiral winding, the lower film edge does not need to hang on the divider plate if it overlaps the first (previously wound) film.

[0023]

As described above, according to the present invention, the film does not come into direct contact with the wound body when stretch-packing the laminated body of the wound body. The remarkable effect is that the wound body is not damaged due to the occurrence of the above.
