[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a contact preventive tool capable of effectively preventing the lower end portions of the surface-treated material from coming into contact with each other in the surface treatment performed by suspending the surface-treated material such as an aluminum mold member on a transport frame.

[0002]

[Prior art]

 Vertically suspended surface treatment is usually carried out by suspending a large number of surface-treated materials through a dedicated jig at a specified interval on a conveyor frame. If the lower end of the material is not prevented from swinging, the lower ends of adjacent materials or multiple materials will inadvertently contact each other, damaging the surface of the material before surface treatment, or cleaning the treated surface after surface treatment. It may be damaged or the materials may become entangled during solution dipping or electrolytic treatment, leading to poor surface treatment.

In order to prevent the occurrence of such a situation, conventionally, conventionally, an end holding device as shown in Japanese Utility Model Publication No. 59-13245 is generally used. As shown in FIG. 7, the conventional end holding device is provided with a large number of holding clips 11 and a long connecting bar 12 connecting the holding clips 11 at predetermined intervals. 11, a main body of the V-shaped body is formed into a substantially V-shape, and a holding claw 13 extending linearly is formed at an end edge of the one-side piece 11a of the V-shaped main body. A regulation plate in which an end portion is formed with a bifurcated holding claw 14 that extends after being bent in the direction of the holding claw 13 while an operating lever 15 is engaged between the one side piece 11a and the other side piece 11b. 16 is configured to be hooked to regulate the elastic V-shape of the clip body, and the holding levers 13 and 14 can be separated from each other by closing the V-shape of the body by the lever action of the operation lever 15. Has become. In the latter long connecting bar 12, the main body is formed of a metal wire, and an inverted U-shaped fastening portion 17 is integrally formed on the main body at a distance equal to the hanging distance of the surface treated material. In addition, the V-shaped main body of the holding clip 11 is individually attached to each of the fastening portions 17.

Therefore, in actual use, a large number of holding clips 11 are attached to the respective fastening portions 17 of the above-mentioned long connecting bar 12 and are hung on a carrying frame via a jig. If the lower end portion Wa of the material is clamped between the two holding claws 13 and 14 of the corresponding holding clip 11 by the pressing operation of the operating lever 15, the lower end portion Wa of the adjacent material can be hung. Can always be held constant, and this holding state prevents the lower end portion Wa of the surface-treated material from swinging independently. Therefore, even if the lower end portion Wa of the surface-treated material swings during transportation, the lower end portion Wa of each material always has a hanging interval due to the holding state in which the lower end portion Wa is constrained in series. Since they only work together while being held constant, the lower ends of adjacent materials or multiple materials inadvertently contact each other, causing damage to the surface of the material before surface treatment or treatment after surface treatment. It is possible to effectively prevent the surface from being damaged, or the materials being entangled with each other during the solution immersion or the electrolytic treatment to induce a defective surface treatment.

[0005]

[Problems to be solved by the device]

 However, in such a conventional end holding device, not only two separate parts, the holding clip 11 and the connecting bar 12, but also a large number of holding clips 11 connected to the connecting bar 12 have a complicated structure. Therefore, it goes without saying that the apparatus itself becomes large-scaled and the cost becomes high, but in particular, the conventional edge holding device does not remove the lower end portions of all the surface-treated materials. Based on the concept of constraining in series, even when holding the lower end Wa of the surface-treated material, or conversely, when releasing the lower end Wa of the material, complicated operation of the operating lever 15 is performed. Therefore, it is necessary to individually hold the lower end portions Wa of all the materials between the two holding claws 13 and 14 of the corresponding holding clip 11 and to release the held state individually, which makes the work troublesome. Big size There is a problem.

Further, in the conventional end holding device, as described above, the holding clip 11 is preliminarily attached to the fastening portion 17 of the connecting bar 12 at an interval equal to the hanging interval of the surface treated material. Therefore, there is also a problem in that the flexibility of the surface-treated materials W having different hanging intervals is lacking and the range of use thereof is significantly limited.

[0007]

[Means for Solving the Problems]

 The present invention was developed under a truly innovative idea in the field in order to effectively solve such conventional problems, and is detachably attached to the surface treated material side. Contact preventive device for surface treated material, which comprises a central mounting portion and an outer peripheral flange portion which is located on the outer periphery of the central mounting portion and prevents the lower end portion of the adjacent surface treated material from entering in the direction of the central mounting portion. Is intended to be provided.

[0008]

[Action]

 Therefore, according to the present invention, unlike the conventional end holding device, even if the lower end portions of all the surface treated materials are not constrained in series, the surface treated material hung on the transport frame can be used. Therefore, it is possible to reliably prevent contact between the lower end portions of the surface-treated material by the action of the outer peripheral flange portion, simply by attaching the contact preventive tool every other piece through the center attachment portion. Compared with the large-scaled end holding device, the mounting / removing work is very simple and the structure is greatly simplified.

【Example】

 Hereinafter, the present invention will be described in detail with reference to each illustrated embodiment. The contact prevention tool 1 according to the first embodiment was developed as an internal attachment for a pipe-shaped surface treated material having an internal cavity, and as shown in FIG. 1, one metal wire rod having excellent corrosion resistance. A pair that are integrally formed to define a central mounting portion 2 having a substantially inverted U-shape that is elastically deformable and that extends in opposite directions from both ends of the central mounting portion 2. Of the horizontal portions 3 and a pair of rising portions 4 that are bent upward from the end portions of the respective horizontal portions 3 are defined, and finally, a center mounting is performed from the end portions of the respective rising portions 4. It is configured to define a pair of outer peripheral flange portions 5 curved in an arc shape toward the outer peripheral direction of the portion 2. Therefore, in the contact preventive tool 1 of the first embodiment, as shown in the figure, a pair of outer peripheral flange portions 5 are located on the outer periphery of the inverted U-shaped center mounting portion 2 in a substantially concentric circle and are adjacent to each other. It is possible to reliably prevent the lower end of the surface-treated material from entering in the direction of the central mounting portion 2, and by pressing the pair of opposed rising portions 4 inward, the central mounting portion 2 has an inverted U-shape. It is possible to easily narrow the width of. The overall shape of the pair of outer peripheral flange portions 5 is not limited to the illustrated regular circle, and may be a quadrangle, hexagon, octagon, or the like as long as it can prevent the lower end portion of the surface-treated material from entering. Other shapes may be used.

Therefore, when the contact preventive tool 1 having such a configuration is used to prevent contact between the lower ends Wa of the pipe-shaped surface-treated materials W suspended on the side of the transport frame (not shown), As shown in FIG. 2, while pressing the pair of rising portions 4 inward to narrow the inverted U-shape of the center mounting portion 2, the center mounting portion 2 is inserted into the inside from the lower end opening of the material W. , When the pressed state against the rising portion 4 is released, the center mounting portion 2 expands to its original shape and surely presses the inner wall surface of the material W with elastic force. Therefore, the lower end of the surface treated material W is The contact prevention tool 1 can be easily attached to the portion Wa. It is needless to say that the contact preventive tool 1 can be easily attached to the lower end portion Wa even after suspending the surface-treated material W once in the transport frame. The contact preventive tool 1 can be easily attached even under the condition that it is placed on the pallet for transporting, and in any case, the attachment workability becomes extremely good. Moreover, in the first embodiment, the center mounting portion 2 having the inverted U-shape capable of elastic deformation makes it possible to considerably absorb the difference in diameter of the pipe-shaped material W. The flexibility can be greatly expected even for materials W having different diameters.

Therefore, after that, the mounting work is repeated, and as shown in the drawing, the contact prevention tool 1 is sequentially mounted on every other material W that is hung on the transport frame side. For example, hereafter, no matter how the lower end portion Wa of the surface-treated material W is shaken during transportation, every other piece is attached to the lower end portion Wa of the material W as shown in FIG. The presence of the outer peripheral flange portion 5 of the contact preventer 1 reliably prevents the lower end portions Wa of the material W from contacting each other, so that the lower end portion Wa of the adjacent material W or a plurality of the material W is not prepared. Contact the surface of the material W to damage the surface of the material W before the surface treatment, damage the treated surface after the surface treatment, or entangle the material W during solution dipping or electrolytic treatment to induce defective surface treatment. It is possible to effectively prevent such things.

When the contact prevention tool 1 is removed from the lower end Wa of the surface-treated material W after finishing the surface treatment process, a finger is hung on the horizontal portion 3 extending from both ends of the center mounting portion 2. By pulling, the center mounting portion 2 can be elastically deformed and easily pulled out from the lower end opening of the material W, so that the work for removing the contact preventive tool 1 can be performed easily. . Moreover, this can be said at the time of mounting work, but unlike the conventional end holding device, the contact prevention device 1 itself is attached to the surface-treated material W every other piece independently. Therefore, the workability is simplified from this point as well.

Next, the contact preventive tool 1 according to the second embodiment will be described. In the first embodiment, the center mounting portion 2 is formed in an inverted U shape, and the center mounting portion 2 in the inverted U shape is formed. While the internal cavity of the pipe-shaped material W is used for internal attachment, this second embodiment is intended for external attachment to other materials W that cannot use the internal cavity. Was developed as. In the drawings, for the sake of convenience, a solid round material is targeted, but the present invention is not limited to this, and other cross-sectional shapes including a plate shape can be used as long as they can be externally attached. May be

Therefore, as shown in FIG. 4, the contact preventive tool 1 according to the second embodiment continuously defines the above-mentioned horizontal portion 3 and upwardly extends from both ends of the continuous horizontal portion 3. In terms of defining a pair of bent rising portions 4 and defining a pair of outer peripheral flange portions 5 curved in an arc shape from the end of each rising portion 4 toward the outer peripheral direction, Although it is common to the embodiment, the difference is that a pair of lateral U-shaped gripping portions 6 extending in the center direction from the respective end portions of the pair of outer peripheral flange portions 5 and intersecting each other are defined, and the facing portions are opposed to each other. A pair of gripping portions 6 that intersect each other is used as the central mounting portion 2 is adopted. Therefore, even in the second embodiment, as a result, the pair of flange portions 5 are located substantially concentrically on the outer periphery of the center mounting portion 2 and the lower end portion Wa of the adjacent surface-treated material W is adjacent to each other. Although it is possible to reliably prevent the intrusion in the direction of the central mounting portion 2, if the opposed tip portions 5a of the respective flange portions 5 of the extended grip portion 6 are pressed inward, the pair of grip portions 6 define Therefore, the holding space 7 can be easily opened.

Therefore, in the case of using the contact preventive tool 1 of the second embodiment to prevent the lower end portions Wa of the large number of surface-treated materials W suspended on the transport frame side from contacting each other, this time, The tip end portion 5a of each of the flange portions 5 is pressed inward to expand the holding space 7 of the center mounting portion 2 formed of the pair of gripping portions 6, while the lower end of the material W is held in the holding space 7. When the portion Wa is inserted and the pressed state against the outer peripheral flange portion 5 is released, the holding space 7 of the center mounting portion 2 is reduced in diameter to its original shape, and the outer wall surface of the material W is removed by the pair of grip portions 6. Since it securely holds the contact preventive tool 1 together with the elastic force, the contact preventive tool 1 can be easily attached to the lower end portion Wa of the surface-treated material W as shown in FIG. Even in the second embodiment, since the center mounting portion 2 is composed of the pair of gripping portions 6 that can be expanded, the diameter difference of the material W can be considerably absorbed. Even for materials W having different differences, the flexibility can be greatly expected.

Therefore, after that, by repeating such an attaching operation, as shown in FIG. 6, the contact preventive tool 1 is attached to every other material W hung on the transport frame in sequence. For example, no matter how the lower end portion Wa of the surface-treated material W swings during transportation, every other piece is attached to the lower end portion Wa of the material W as in the case of the first embodiment. Due to the presence of the outer peripheral flange portion 5 of the contact prevention tool 1, the contact between the lower end portions Wa of the material W is reliably prevented. Further, when removing the contact preventive tool 1 from the lower end portion Wa of the surface-treated material W, the horizontal portion 3 may be pulled with a finger as in the first embodiment. It is possible to remove the contact prevention tool 1 from the lower end portion Wa of the material W even when the tip end portion 5a is pressed to expand the holding space 7 of the center attachment portion 2 formed of the pair of grip portions 6. Therefore, also in the second embodiment, the attachment / removal work of the contact prevention tool 1 is very simple.

In each of the above examples, the contact preventive tool 1 is integrally formed of a metal wire material such as a titanium alloy or stainless steel having excellent corrosion resistance in consideration of ease of molding. It goes without saying that it is also possible to mold this with a synthetic resin material, or to mold the center mounting part 2 and the outer peripheral flange part 5 separately and then to join the two 2.5 together. However, in particular, when the contact prevention tool 1 formed of a metal wire is used for colored surface treatment, there is a risk of contact with the material W including the central mounting portion 2 in order to prevent the occurrence of color spots. It is preferable to apply rubber or resin coating to a certain part to keep it insulated.

[Effect of device]

 As described above, according to the present invention, by adopting the above configuration, the surface treated material can be hung on the transport frame without the lower end portions of all the surface treated materials being constrained in series like the conventional end holding device. On the other hand, if every other contact preventive tool is attached independently, the contact between the lower end portions of the surface-treated material can be reliably prevented by the action of the outer peripheral flange portion. Compared with the end holding device, the work of mounting and removing the end holding device is very simple and structurally greatly simplified. Moreover, the contact preventive device of the present invention is not limited in its use by the hanging interval of the surface-treated material, and the center mounting portion can reduce the diameter difference of the target surface-treated material. Since it can be absorbed considerably, in any case, it also has the advantage that its range of use can be significantly expanded.
