[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improved technique of a packaging corrugated box for accommodating and holding a bobbin in which an electric wire or the like is wound around a central shaft portion.

[0002]

[Prior art]

 Various types of corrugated cardboard boxes for packaging have been conventionally provided.For example, a partition plate having a general strength is attached to the inside of the box body, or a bobbin inside the box body by pushing a padding. Those that regulate the free movement of the are known.

However, since the conventional one has not been developed in consideration of the weight and size of the bobbin, the bottom wall and the partition plate may be crushed by the weight of the bobbin during transportation, or the inside of the box body may be damaged. Since the positioning of the bobbin was uncertain, the bobbin could freely roll inside and hit the front and rear walls of the box body, causing the front and rear walls to break.

Therefore, the material of the box body, partition plate, etc. is changed to one with high strength, or a mold such as Styrofoam is used for reliable positioning to allow free rolling in the box body. It was also considered to prevent the box body from being broken.

[0005]

[Problems to be solved by the device]

 However, if the whole of the box body and the partition plate is made of a special material having high strength as described above, not only the molding work becomes difficult, but also the material cost is inevitably soared.

Further, when a mold such as Styrofoam is used, its use tends to be restricted in the future due to the problem of environmental pollution due to the generation of harmful gas during incineration at the time of disposal after use. Therefore, the development of a packaging box in which all the components are made of corrugated cardboard is desired.

[0007]

Further, substantially triangular support holes 23, 23, 24, 24, 25, 25, 26, 26 are provided in upper and lower two steps at the lower portions of the opposite side walls 17, 18 at both side portions 17a, 17b, 18a, 18b. The support members 27, 28 made of corrugated cardboard are inserted through the support holes 23 1, 23, 24, 24 on the upper side facing each other.

Each of the support holes 23 to 26 is formed at a position facing each other in the horizontal direction in the upper and lower stages, and the height from the upper surface of the bottom plate 19 is set at a position corresponding to the outer diameter of the bobbin 2. Has been done. That is, the upper support holes 23, 23, 24, 24 are set at positions substantially horizontal to the axis X of the small-diameter bobbin 2a, as shown in FIG. 2, while the lower support holes 25 are provided. , 25, 26, and 26 are set at horizontal positions corresponding to the vicinity of both outer peripheral lower end edges of the large-diameter bobbin 2b, as shown in FIG. The upper support holes 23 to 24 are formed in an equilateral triangle shape, while the lower support holes 25 to 26 are formed in a right triangle shape.

The support members 27 to 29 are formed by bending a long flat plate from the center position in the width direction into a substantially V shape in accordance with the shape of the support holes 23 to 26. , 28 have the same length in the width direction of the upper and lower pieces, while the lower-stage side support members 29, 30 are smaller than those of the horizontal upper pieces 29a, 30a in the width direction of the bobbin 2b. The lengths in the width direction of the lower pieces 29b and 30b that are inclined in the X-axis direction are set to be large. Therefore, the tip edges 27c to 30c of the upper and lower stage side support members 27 to 30 are oriented in the axial X direction of the bobbins 2a and 2b. Further, the support members 27 to 30 are detachably provided in the support holes 23 to 26, and the upper and lower support holes 23 to 26 are appropriately selected according to the size of the bobbins 2a and 2b housed inside. It is designed to be inserted through.

The operation of this embodiment will be described below. First, in order to accommodate the small-diameter bobbin 2a in the box body 1, the support frame 3 in which the pair of support members 27, 28 are inserted and arranged in advance in the respective support holes 23, 23, 24, 24 facing each other on the upper stage side. Is mounted in the box body 1 from above. After that, when the upper end of the small-diameter bobbin 2a in which the electric wire 2d is wound around the central shaft 2C is held and is inserted into the inside of the support frame 3 from above through the notches 20 and 21, the bobbin as shown in FIG. The outer peripheral lower end line of 2a is placed and supported on the upper surface of the bottom plate 19, and at the same time, both end edges of the outer peripheral edge in the diametrical direction are brought into contact with and supported by the respective tip edges 23c, 24c of both supporting members 23, 24, and the whole is Supported by 3 points.

Therefore, the bobbin 2a can be reliably positioned in the box body 1, and free rolling can be restricted. Therefore, it is possible to reliably prevent the support frame 3 and the box body 1 from being crushed during transportation.

In particular, the support members 27, 28 have a V-shaped tip edge 27c, 28c, and the component force of the rolling force of the bobbin 2a acts substantially evenly on the upper and lower pieces from the tip edge 27c, 28c. Since the upper and lower pieces function as beam members, the supporting rigidity is increased. As a result, a more reliable supporting force can be obtained and the supporting members 27 and 28 themselves can be prevented from being crushed. Further, since the support members 27 and 28 are made of corrugated cardboard having high compressive strength, the support rigidity is further increased in this respect as well, and the crushing of the support members can be further prevented.

Further, since the bottom plate 19 is also formed of corrugated cardboard paper having high compressive strength, it is not easily crushed.

Next, in order to accommodate the large-diameter bobbin 2b in the box body 1, a pair of support members 29, 30 are inserted and arranged in advance in the corresponding support holes 25, 25, 26, 26 on the lower stage side. The supporting frame 3 is mounted in the box body 1 from above. After that, when the large-diameter bobbin 2b around which the electric wire 2d is wound is loaded into the support frame 3 as described above, when the lower end line of the bobbin 2b is placed and supported on the upper surface of the bottom plate 19 as shown in FIG. At the same time, the lower end edges of the outer periphery are abutted and supported by the respective tip edges 29c, 30c of the support members 29, 30, and the outer circumferential end edges in the diametrical direction are opposite surfaces 15a, 16a of the front and rear end walls 15, 16. Will be supported immediately, and the whole will be supported at 5 points.

Therefore, the large-diameter bobbin 2b can be reliably positioned within the support frame 3, and free rolling can be restricted, so that the support frame 3 and the box body 1 can be prevented from being crushed during transportation. Is the same as described above.

Since the lower pieces 29b and 30b of the respective support members 29 and 30 are oriented in the axial direction of the bobbin 2b, the component force of the rolling power of the bobbin 2b is inclined with respect to the horizontal upper pieces 29a and 30a. The lower pieces 29b, 30b are shaped to act substantially uniformly, and both pieces 29a, 29b, 30a, 30b function as beam members, so that the supporting rigidity is increased. Therefore, the same effect as that of the above-described embodiment can be obtained. Also, from the point of view of a material having high compressive strength, the same operational effect as that of the above-mentioned embodiment can be obtained.

Moreover, since the support frame 3 in each of the embodiments is integrally formed by bending a piece of corrugated paper, the forming process is extremely easy and the cost can be reduced. Also, problems such as environmental pollution at the time of disposal can be eliminated.

Further, since the supporting members 27, 28, 29, 30 are appropriately selected according to the size of the bobbins 2a, 2b to change the supporting positions for the bobbins 2a, 2b, The bobbins 2a and 2b can be supported more reliably.

Further, by appropriately selecting the supporting members 27, 28, 29 and 30, one and the same box body 1 and supporting frame 3 can be used as they are regardless of the size of the bobbins 2a and 2b. Also in this respect, the manufacturing workability is improved and the cost can be reduced.

The supporting members 27, 28, 29, 30 and the bottom plate 19 may be made of general strength instead of corrugated cardboard having high compressive strength.
