Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cheese winding packing fixing plate which is used when a plurality of cheese winding threads wound on a bobbin are stacked in a packaging box for collective packaging. .

[0002]

2. Description of the Related Art The prior art can roughly divide this into two methods.

As one method, for example, as shown in FIG. 7, a hat type synthetic resin bobbin locking tool 21 having a flange 23 extending from a lower end edge of a cap-shaped main body 22 is used. Are inserted into the respective holes 24 of the support plate 25 having a large number of holes 24 and are attached to the support plate 25, and the bobbin of the winding body 20 is attached to each bobbin locking member 21 attached to the support plate 25. By fitting the 10 ends, a large number of thread bodies 20 are supported by the bobbin locking tool 21 to the support plate 2
It is a method to lock it at a predetermined position on the 5 (Example: Shokai 5
3-161988). When stacking the wound bodies 20 in multiple stages by this method, as shown in the figure, the single cap-shaped bobbin locking tool 21 is directly attached to the uppermost and lowermost support plates 25. A pair of single-cap-shaped bobbin engaging members 2 are used for the intermediate supporting plate 25.
1 uses a double-cap type bobbin locking tool 26 having a shape in which the flange 23 is integrally connected.

Another method is, for example, as shown in FIG. 8, a perforated pad 2 made of expanded polystyrene having a hole 27.
It is a method using 8. Such a perforated pad 28
In the packing method using, the first-stage perforated pad 28 is first placed in a packaging box (not shown), and then the hole 27 of the perforated pad 28 is inserted into the lower shoulder portion of the cheese winding yarn 20. 20 '
The bobbin 10 of the cheese winding yarn 20 is inserted until the pad 28 contacts the pad 28. Next, the second-stage perforated pad 28 is put into the packaging box from above, and the hole 27 of the perforated pad 28 is fitted to the upper portion of the bobbin 10.

At this time, the perforated pad 28 is sufficiently inserted until it contacts the upper shoulder portion 20 'of the cheese winding yarn 20. This method is the same as above
This is a method in which the third-stage cheese winding yarn 20 and the third-stage and fourth-stage perforated pads 28 are alternately placed in a packaging box (eg, Japanese Patent Publication No. 54-5760).

However, in recent years, as many cheese winding threads as possible have been wound around a bobbin of the same size in order to reduce the cost. The size of the bobbin protruding upward and downward of the cheese winding becomes smaller and smaller.

Therefore, when such cheese winding yarns are collectively packaged by the conventional method as described above, the following problems have occurred.

That is, when such a cheese winding thread having an excessively large winding diameter is fixed by the former paper tube supporting method using a conventional bobbin locking tool, the shoulder portion 20 of the cheese winding thread 20 is fixed. Since there is a large gap between the ‘′ and the support plate 25, the cheese winding thread supported only by the bobbin locking tool 21 only at its center portion is likely to vibrate (wobble easily) in the large diameter winding thread portion. The problem is that it is very unstable, and if the cheese winding is in the shape of a disk, vibration and shock during transportation tend to cause a line edge and / or step edge, and once such trouble occurs. However, there has been a problem that a yarn breakage may occur due to the tension acting on the yarn during unwinding.

In this regard, according to the latter conventional method, the above-mentioned problems do not occur, but when the heavy cheese winding threads are collectively packaged by the latter conventional method as in recent years. Is applied to the winding end surface (the shoulder portion 20 ′) of the lower winding thread as it is through the perforated pads 28 interposed between the respective cheese winding threads. As a result, an excessive vertical compression force acts on the lower cheese winding yarn, which causes a problem that the lower cheese winding yarn is distorted and the yarn quality is deteriorated.

Therefore, the present inventor eliminates both the drawbacks of the former prior art and the latter of the latter prior art as described above.
A novel packing plate for cheese winding yarn as disclosed in Japanese Patent No. 4455 was developed (see FIGS. 9 and 10).

That is, a corrugated board 33 having an appropriate thickness is arranged at an appropriate number to form an appropriate number of holes 32, and a flange 36 is provided at each of the holes 32 at the opening edge of a cap-shaped main body portion 35. Is a fixed plate 31 for packing cheese winding yarn, in which a hat-shaped synthetic resin bobbin locking tool 34 is attached, and a step 37 is provided on a cap-shaped main body part 35 of the bobbin locking tool 34. This is a cap-shaped body part 3 that is formed
5 is a portion 3 far from the collar portion 36 with the step portion 37 as a boundary.
5a is formed to have a smaller diameter than the portion 35b following the flange portion, and is a convex shape that fits on the inner peripheral surface of one bobbin 10 end with the outer peripheral surface of the small diameter portion 35a and the outer surface of the step portion 37 following it. The fitting portion 38 is formed, and the inner peripheral surface of the large-diameter portion 35b and the inner surface of the step portion 37 that follows the inner peripheral surface of the large-diameter portion 35b form the other bobbin 1
A concave fitting portion 39 that fits on the outer peripheral surface of the zero end is configured, and the main body portion 35 of the bobbin locking tool 34 is provided in at least the hole 32 portion of the corrugated board plate 33 in the corrugated board plate 33. When the bobbin engaging member 34 is inserted
7 is located in the hole 32, and the end of the bobbin is located in the hole 32.
A cheese winding packing fixing plate 31 having a plate thickness to be fitted into the convex fitting portion 38 therein has been developed.

The cheese winding packing fixing plate 31 constructed as described above has a bobbin engaging member 34 mounted in the hole portion 32 of the corrugated board 33 so that one bobbin is formed on one surface of the plate 33. A convex fitting portion 38 that can be fitted to the inner peripheral surface of the 10th end is formed, and a concave fitting portion 39 that fits to the outer peripheral surface of the other bobbin 10 end is formed on the other surface of the plate 33. Moreover, since the step portion 37 of the bobbin locking tool 34 which is a boundary between the fitting portions 38 and 39 is located in the hole 32 of the corrugated board 33, it is suitable for the corrugated board 33. If the plate thickness is given, the cheese winding packing fixing plate 31 can be used as follows (see FIG. 9).

That is, using the fixing plate having such a structure, the cheese winding yarns are stacked in two or three or more layers, and the packaging box 15 is formed.
In packaging in a box, for example, if the bobbin engaging member 34 attached to the bobbin engaging member 34 is fixed to the corrugated cardboard plate 33, the fixing plate 31 of the first stage is first placed in the packaging box 15.
Is inserted so that the concave fitting portion 39 of the bobbin engaging member 34 faces upward, and then the concave fitting portion 39 of the bobbin engaging member of the fixing plate 31 is inserted into the cheese winding of the first stage. The bobbin 10 of the thread 20 is fitted, and the lower end surface of the bobbin 10 is attached to the bobbin locking tool 3
When the upper surface of the step portion 37 of No. 4 is abutted, the cheese winding thread 20
The lower surface 20a of the winding yarn can be brought into contact with the upper surface of the fixing plate. Next, from the upper side to the packaging box 15, the second
The fixing plate 31 of the step is inserted so that the concave fitting portion 39 of the bobbin locking tool 34 attached to the fixing plate 31 faces upward.
The convex fitting portion 38 of the bobbin locking tool 34 of the fixing plate 31 is fitted to the bobbin 10 of the cheese winding 20 so that the lower surface of the stepped portion 37 of the bobbin locking tool 34 is the upper end surface of the bobbin 10. The fixing plate 31 is held at a predetermined height inside the packaging box 15 via the bobbin 10 when the bobbin 10 is struck. Therefore, after that, in the same manner as above,
The cheese winding threads 20 of the second stage and above and the fixing plate 31 of the third stage and above are put in the packaging box 15 to obtain these cheese winding threads 20.
If the bobbin 10 of each cheese winding yarn 20 is packaged, the convex fitting portion 38 and the concave fitting portion of the two fixing plates 31 fitted to the upper and lower ends of the bobbin 10 from above and below. 39, the upper and lower ends thereof are similarly held in the case of the support plate 25 using the conventional cap-shaped bobbin locking device 21 disclosed in Japanese Utility Model Laid-Open No. 53-161988. The winding thread portion of the cheese winding thread 20 corresponds to each cheese winding thread 20.
Each time, the load is placed on the fixed plate 31 thereunder via the bobbin 10 on which the wound yarn is wound and the upper surface of the fixed plate 32 with which the lower surface 20a of the wound thread 20 portion is in direct contact. Will be supported.

Since the corrugated board plate 33 has at least the following plate thicknesses, that is, when the main body portion 35 of the bobbin engaging member 34 is inserted into the hole 32 of the corrugated board plate 33, The step portion 3 of the bobbin lock 34
Since 7 is located in the hole 32 and the end portion of the bobbin 10 is fitted in the convex fitting portion 38 in the hole 32, a plate thickness is given in advance, If these thick plates are set appropriately, the fixing plates 31 are placed in the packaging box 15 with the convex fitting portions 38 of the bobbin engaging members 34 attached thereto facing upward. Even if you put it in
The cheese winding 20 can be supported by the lower fixing plate 31 in the same manner as above by bringing the lower surface 20a of the winding portion of the cheese winding 20 into contact with the upper surface of the fixing plate 31.

[0015]

As described above, according to the cheese winding packing fixing plate previously developed by the present inventor,
At least, as described above, the effect of being able to fix the upper and lower cheese winding tubes with one fixing tool can be achieved, but then the fixing plate is repeatedly used for packing cheese winding threads. As a result, it was found that the cheese winding packing fixing plate disclosed in JP-A-1-294455 still has the following problems.

That is, the fixing plate 31 is mounted in the hole 32 of the corrugated board 33 when the overload repeatedly acts on the step portion 37 of the main body portion 35 from the convex fitting portion 38 of the bobbin engaging member 34. The bobbin locking device 34 is attached to the corrugated board 3
Even when the bobbin locking tool 34 is adhered and fixed to the fitting recess 41 formed in 3, the bobbin locking tool 34 is easily peeled off from the corrugated board 33 due to an impact received during transportation or the like. In this case, when the packaging box 15 is grounded in a tilted state, the bobbin locking tool 34 is peeled from the corrugated board 33, or when it is peeled off, the bobbin locking tool 34 becomes cheese. The cheese winding thread 20 that should be pulled out from the hole 32 of the corrugated board 33 due to the load of the winding thread 20 and should be held at the position of the hole 32 of the corrugated board 33 through the bobbin locking tool 34 in the packaging box 15. It turned out that there was a problem that the load collapsed and it was damaged.

Therefore, the present invention is to improve the invention previously developed by the present inventor and to provide a cheese winding packing fixing plate in which the above problems are solved.
