Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to an anodizing apparatus for suspending a large number of surface-treated materials such as aluminum molds on a carrier frame to perform surface treatment on the carrier frame. The present invention relates to an improvement of a hanger for suspending materials.

"Prior Art" An example of a conventional hanging device of this type will be described. As shown in FIG. 4, a release lever 2 can be opened and closed via a connecting leaf spring member 3 on a base body 1 attached to the conveyance frame side. On the other hand, by using a part of the leaf spring material 3, a holding claw 4 having a sharp tip is integrally provided at the tip end portion of the opening lever 2 to obtain a spring pressure obtained from the leaf spring material 3. Then, the surface treated material can be held between the sharp tip edge 4a of the holding claw 4 and the facing holding surface 1a of the base 1 according to the thickness thereof.

Then, in actual use, against the spring pressure of the leaf spring material 3, the opening lever 2 is manually or mechanically operated to move the holding claw 4 in the opening direction, and the holding claw 4 and the base body are moved. After inserting the surface-treated material between the holding surfaces 1a of 1 and then releasing the operation of the release lever 2, the surface-treated material is provided with the sharp tip edge 4a of the holding claw 4 and the holding surface 1a of the base body 1.
It will be held in between.

"Problems to be solved by the invention" However, in such a conventional hanging tool, the tip edge of the holding claw 4 on the side of the opening lever 2 is formed into a pointed shape, and the pointed tip edge 4a bites into the surface treated material. Since it is assumed that the surface treated material is a plate-like material, the sharpened tip edge 4a of the sandwiching claw 4 should surely hold the surface treated material of the plate-like object. However, when the surface-treated material has an irregular shape such as a round or rectangular cross section, the sharp shape of the tip edge of the holding claw 4 is greatly deteriorated, and There is a sufficient possibility that the state of being held against the surface-treated material becomes extremely unstable, and the surface-treated material being conveyed may inadvertently rattle or drop.

Therefore, when holding a surface-treated material having a different shape such as a round cross section or a square shape using a conventional hanging tool, as shown in FIGS. A flat clamping margin Wa is formed on the upper end of the surface-treated material W of the body, and the flat clamping margin Wa is clamped by the sharp tip edge 4a of the clamping claw 4.

However, the flat surface holding material W has a flat shape
Forming Wa requires a complicated pressing process or cutting process for forming the holding margin Wa individually for each surface-treated material in the pre-process of surface treatment, so that work efficiency is improved. There will be a problem that it will get worse.

Therefore, in the field, even if the flat gripping allowance Wa is not formed, the surface-treated material W having an irregular shape such as a round cross section or a square cross section can be surely held with the shape as it is. The advent of a new hanging device that can do this is highly desired.

"Means for Solving the Problem" The present invention was developed to meet such a request, and includes a base body having a holding surface at the tip, and a release lever having a holding claw at the tip. And a holding tool for holding the surface-treated material between the holding claws of the opening lever and the holding surface of the base body according to its thickness, at least the holding claw of the opening lever has a bifurcated shape. However, a construction is adopted in which the surface treated material is held by both inner edges of the bifurcated holding claw.

"Effect" Therefore, even in the hanging device of the present invention, if the holding claw is moved in the opening direction by the operation of the release lever, the surface treated material is inserted between the holding claw and the holding surface of the base body. It goes without saying that the surface treated material can be sandwiched between the sandwiching claw and the sandwiching surface of the base body, but in the sandwiched state of such surface treated material, the sandwiching claw has a bifurcated shape. Even if the surface-treated material has an irregular shape such as a round or square cross section, these surface-treated materials are pressed by the inner edges of the holding claw within the bifurcated shape of the holding claw. Depending on the state, it will be sandwiched between the sandwiching surfaces of the base body, so it is possible to securely and stably sandwich even the surface-treated material of a different shape without forming a flat sandwiching allowance as in the past. Become.

[Examples] Hereinafter, the present invention will be described in detail with reference to each illustrated example. The suspending tool according to the first example also includes a base 11 attached to the transfer frame side as shown in FIG. While the open lever 12 is openably and closably connected via the connecting leaf spring member 13, the tip of the connecting leaf spring member 13 is used to integrally provide a holding claw 14 on the tip end side of the opening lever 12. The holding claw 14 and the holding surface 11 at the tip of the base 11 by the spring pressure obtained from the leaf spring material 13.
It is premised that the surface treated material is held between a and a according to the thickness thereof, which is characterized by the following configuration.

That is, in this embodiment, the holding claw 14 provided on the tip side of the opening lever 12 is cut into an inverted V shape by utilizing the tip of the connecting leaf spring material 13. In addition, the two-forked holding claw 14 is configured to hold the surface-treated material W at both inner edges of the two-forked holding claw 14. still,
The rear end side rising portion 13a of the leaf spring material 13 is a stopper portion that restricts the opening operation of the opening lever 12.

Therefore, when the surface treated material W is held by using the suspending tool having such a structure, the leaf spring material 13 is used as in the conventional case.
Against the spring pressure of the holding lever 12, the opening lever 12 is manually or mechanically operated to move the holding claw 14 in the opening direction to move the holding claw.
After inserting the surface treated material W between the holding surface 11a of the base 14 and the holding surface 11a of the base 11, the operation of the release lever 12 is released, and the surface treated material W is held between the holding claw 14 and the holding surface 11a of the base 11. It can be held depending on the wall thickness.

However, in the present embodiment, as described above, the holding claw 14 provided at the tip of the opening lever 12 is formed into a bifurcated shape that is cut in an inverted V shape. Even if the treatment material W has an irregular shape such as a round cross section or a square cross section, as shown in the drawing, these surface treated materials W are inside the bifurcated shape of the gripping claws 14 on both inner sides of the gripping claws 14. The holding surface 11a of the base 11 with the edge being pressed at two points.
Since it is sandwiched between them, it is possible to surely sandwich even the surface-treated material W having a different shape without forming a flat sandwiching allowance Wa as in the conventional case.

Although the drawings show the state where the rectangular surface-treated material W is held, it is needless to say that the round material W can also be held reliably under the same principle. Further, in this embodiment, by using the two sharp tip edges existing on both sides of the bifurcated claw 14, the surface treated material of the plate can be held more securely than before. It becomes possible.

Next, explaining the hanging device according to the second embodiment,
The second embodiment is based on the structure of the first embodiment as it is, except for the difference as shown in FIG.
Also on the holding surface 11a of the base body 11, two V-shaped holding claws 15 are cut and fixed at fixed intervals, and the base 11
The surface treated material W is held in the space defined between the two forked holding claws 15 on the side and the one forked holding claw 14 on the side of the release lever 12. It is a thing.

Therefore, even in the hanging tool according to the second embodiment, the holding claw 14 and the base 11 are operated by operating the opening lever 12 manually or mechanically against the spring pressure of the leaf spring material 13. Side claws 15
If the surface treated material W is inserted in between, the surface treated material W
Needless to say, it can be held according to its wall thickness, but in the second embodiment, two holding arms 15 and 15 are provided on the holding surface 11a side of the base 11 as well. The surface-treated material W having an irregular shape has upper and lower bifurcated claws 14
・ In the space defined between 15, the respective holding claws 14 ・ 15
Since it will be held in a state of being pressed at 6 points by both inner edges of, the flat holding allowance as before
Even if Wa is not formed,
With the shape as it is, it is possible to reliably hold it.

Incidentally, in particular, the hanging tool of the second embodiment is most effective when holding the round surface-treated material W as shown in the figure, but the same principle applies to the rectangular material W as well. It goes without saying that you can hold it securely under.

Further, a suspending tool according to a third embodiment will be described. In each of the above-mentioned embodiments, a member for connecting the opening lever 12 to the base body 11 so as to be openable and closable and a member for providing spring pressure are connected to each other as a leaf spring material for connection. 13
In addition to the above, the holding claw 14 is formed by utilizing the tip end portion of the leaf spring material 13 to simplify the suspending tool itself. As shown in FIG. 3, support pieces 16a and 16b are provided on the base 11 and the release lever 12, respectively, and the support pieces 16a and 16b are pivotally attached via a pivot 17 while the base 11 and the release lever 12 are attached. A coil spring 18 is provided between the rear end portions to provide a spring pressure that serves as a holding force.

Therefore, in the hanging tool of the third embodiment, the two-pronged holding claw 14 is formed as a separate body, and the holding claw 14 is released by the release lever.
If it is fixed to the tip of 12, the spring pressure obtained from the coil spring 18 can be used to treat the surface of the irregularly shaped body without forming a flat clamping margin Wa as in the conventional case, as in the first embodiment. It is possible to reliably hold the material W, but in the third embodiment as well, the two bifurcated holding claws 15, 15 as in the second embodiment are provided on the holding surface 11a side of the base 11. It is also possible to provide.

"Effect of the Invention" As described above, the present invention is characterized in that the holding claw of the release lever is formed into a bifurcated shape, and the surface-treated material is held by both inner edges of the bifurcated holding claw. Therefore, even if the surface-treated material has an irregular shape such as a round or square cross section, these surface-treated materials can be used as long as they are inside the bifurcated shape of the holding claw. Since it will be held between the holding surfaces of the base body in a state of being pressed by,
Even a surface-treated material having an irregular shape can be reliably held in its original shape.

Therefore, according to the present invention, it is not necessary to form a flat holding margin for the surface-treated material having a different shape as in the prior art, which greatly contributes to the rationalization of the surface treatment work.
