Abstract

<P>PROBLEM TO BE SOLVED: To provide a hanging device for hanging down particularly a wide and thin article to be surface-treated, from a transportation frame. <P>SOLUTION: The hanging device for hanging down the article to be surface-treated is directed at vertically hanging down the article in the transportation frame through a hanging tool and sequentially transporting the articles to each treatment tank; and hangs down the article W from the supporting holder 11, so as to make the width side parallel to a transporting direction of the transportation frame by sandwiching a supporting holder 11 with the hanging tool 1. Thereby the hanging device eliminates an anxiety for the contact between the articles W, even when the distance between the hanging tools 1 fixed in the transportation frame is short, and an anxiety for vibration of the article due to air resistance during transportation; and accordingly eliminates an anxiety for the deformation of the article W due to the collision of the article W with an inner wall of the treatment tank, even when the wide and thin article W is immersed in the treatment tank, eliminates the consequent anxiety for the occurrence of bad treatment, allows the article W to be immediately lowered in each treatment tank, and remarkably improves treatment efficiency. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a suspending device used for suspending a material on a conveyance frame in a surface treatment process performed by suspending a surface treatment material such as an aluminum mold on the conveyance frame.

  Usually, when anodizing aluminum mold material, the aluminum mold material is transferred to the treatment line, where each mold material is suspended in a vertically suspended state on a conveyance frame that conveys each mold material to various treatment tanks, For example, it is transported to a degreasing tank, water washing tank, etching tank, water washing tank, neutralization tank, anodized tank (electrolysis tank), water washing tank, color treatment tank, etc., and a predetermined anodizing treatment is performed on the aluminum mold. However, although there are some structural differences as a hanging tool for suspending such an aluminum mold material on the conveyance frame, basically, both of them are a holding body that also serves as an energizing bar, and the holding member. A gripping claw that faces the tip gripping part of the body, an operation lever that opens and closes the gripping claw, and a spring member that imparts a gripping force to the gripping claw (see, for example, Patent Document 1).

Accordingly, a number of the hanging tools are fixed to the conveyance frame at a predetermined interval, and are conveyed to the respective treatment tanks while individually holding the aluminum mold material between the tip holding portion and the holding claws of the holding body. However, when an aluminum mold material is suspended, a method is generally employed in which the mold material is suspended in a state where the width surface thereof is orthogonal to the conveyance direction of the conveyance frame.
Japanese Patent Laid-Open No. 10-219498

  For this reason, in the past, especially when trying to suspend a wide and thin mold material, the mold materials come into contact with each other during conveyance if the interval between the suspension tools fixed to the conveyance frame is narrow. Because there is enough fear, it is necessary to use one or two hanging tools themselves, or to change the interval pitch between the hanging tools, from the viewpoint of productivity and workability I could never say that it was preferable.

  In addition, when transporting wide and thin mold materials to each processing tank using the transport frame, the hanging tool suspends the mold material so that the width surface is orthogonal to the transport direction. As a result of the air resistance, it is easy to vibrate, so that when the aluminum mold is immersed in the processing tank, the aluminum mold is immersed in the processing tank. There is a risk that the mold material itself may be deformed due to collision with the surface, or that a defective surface treatment may occur. Therefore, on the actual processing line, for each processing tank, the vibrating conveying mold material must be stopped after a while and then slowly lowered, so that the processing efficiency is significantly reduced. There was enough.

  The present invention was developed in order to effectively solve the problems of such a conventional suspension device, and the invention according to claim 1 is characterized in that a surface-treated material is vertically attached to a conveyance frame via a suspension tool. A device for suspending a surface-treated material that is suspended in a suspended state and sequentially transported to each treatment tank, holding an auxiliary jig with the above-described suspension tool, and using the auxiliary jig to suspend the surface-treated material. The width surface is suspended in a state parallel to the conveyance direction of the conveyance frame.

  The invention described in claim 2 is characterized in that, on the premise of claim 1, the auxiliary jig held by one hanging tool has a function of hanging two surface-treated materials. .

  Therefore, in the first aspect of the invention, the surface-treated material is brought into a state in which the width surface is parallel to the conveying method of the conveying frame through the auxiliary jig held by the hanging tool. Because it will be suspended, there is no risk of inadvertent contact between the surface-treated materials even when the interval between the hanging tools fixed to the conveyance frame is narrow. It is not necessary to use every other or every two or to change the interval pitch between the hanging tools, so that improvement in productivity and workability can be greatly expected.

  In addition, the fact that the surface treatment material is suspended in a state where the width surface thereof is parallel to the conveyance direction of the conveyance frame almost eliminates the possibility of vibration due to air resistance during conveyance. When the surface treatment material is immersed in the treatment tank, even if the surface treatment material is wide and thin, the surface treatment material itself collides with the inner wall of the treatment tank due to its vibration. As a result, the surface treatment material being conveyed can be immediately lowered for each treatment tank, and the treatment efficiency is significantly improved.

  In the invention according to claim 2, since the auxiliary jig has a function of suspending two surface treatment materials, two surface treatment materials are suspended from one suspension tool. As a result, the processing efficiency is further improved.

  In the present invention, an auxiliary jig is held by a hanging tool fixed to a conveyance frame, and the surface treatment material is suspended by the auxiliary jig in a state where the width surface thereof is parallel to the conveyance direction of the conveyance frame. By lowering, it is intended to provide an optimum suspension device especially for a wide and thin surface-treated material.

  Hereinafter, the present invention will be described in detail with reference to a preferred embodiment. A suspension device according to the embodiment is different from a conventional suspension device in that a plurality of suspension tools are fixed to a conveyance frame at a predetermined interval. The aluminum mold that is the surface treatment material is not suspended directly, but a separate auxiliary jig is once held by the hanging tool, and the width of the aluminum mold with the auxiliary jig is the conveyance direction of the conveyance frame. It is characterized by suspending in a state parallel to.

  First, the suspension tool 1 and the auxiliary jig 11 will be described. As shown in FIGS. 1 and 2, the former suspension tool 1 includes a holding body 2 serving as a current-carrying bar having a tip holding portion 2a, A rotating gripping claw 3 that cooperates with the tip gripping portion 2a of the gripping body 2 to grip a protruding piece 18 of an auxiliary jig 11 described later, an operation lever 4 that opens and closes the rotating gripping claw 3, and a rotation A compression coil spring 5 for applying a holding force to the holding claw 3 is provided, and the connecting structure of the rotating holding claw 3 and the operation lever 4 is provided on the opposing surface of the rotating holding claw 3 and the operation lever 4 as shown in the figure. The gear portions 3a and 4a are connected by occlusion. However, in the present invention, since the hanging tool 1 itself is not so important, it is possible to use other existing hanging tools that directly suspend the aluminum mold material. However, in any case, the hanging tool 1 itself is set to suspend the auxiliary jig 11 or the aluminum mold material in a state orthogonal to the conveying direction of the conveying frame.

  1 and 3, the latter auxiliary jig 11 is basically the same except that the size of the hanging tool 1 is different from that of the hanging tool 1, and a holding body 12 having a tip holding portion 12a. Rotating gripping claws 13 that grip the aluminum mold in cooperation with the tip gripping portion 12 a of the gripping body 12, an operation lever 14 that opens and closes the rotating gripping claws 13, and a gripping force on the rotating gripping claws 13. As shown in the figure, the connecting structure between the rotating holding claw 13 and the operating lever 14 is provided on the operating lever 14 side and the long hole 16 provided on the rotating holding claw 13 side. In addition, the auxiliary jig 11 further includes a protruding piece 18 that is integrally extended from the side edge of the holding body 12 so that the protruding piece 18 is A configuration in which the holder 12 is bent at a right angle is also employed.

  Therefore, in the state where the overhanging piece 18 of the auxiliary jig 11 is held between the holding body 2 of the hanging tool 1 and the rotary holding claw 3, as shown in FIG. In addition, since the relationship between the holding bodies 2 and 12 and the rotating holding claws 3 and 13 is set at a position shifted at a right angle, the holding body 12 and the rotating holding claws 13 on the auxiliary jig 11 side. Unlike the conventional case, the aluminum mold material held between the two is suspended in a vertically suspended state so that the width surface thereof is parallel to the transport direction of the transport frame.

  Therefore, even if the aluminum mold material is to be anodized even under the suspension device having such a configuration, the aluminum mold material is transferred to the treatment line, where each mold material is treated with various treatment tanks (not shown). In this case, as shown in FIG. 5, the upper end portion of the aluminum mold W is assisted as a result of being suspended in a vertically suspended state on a conveyance frame (not shown) that is conveyed via a rail (not shown). A state in which the tip gripping portion 12a of the gripping body 12 of the jig 11 is clamped between the rotary gripping claws 13 is obtained, and each auxiliary jig 11 is individually attached to the corresponding hanging tool 1 via the projecting piece 18. As a result, a large number of aluminum molds W are suspended in a state where their width surfaces are parallel to the transport direction (arrow direction) of the transport frame.

  Therefore, even if the aluminum mold W to be suspended is wide and thin, it is not limited by the fixed interval with respect to the conveyance frame of the hanging tool 1 and is thus fixed to the conveyance frame as in the past. Even if the interval between the hanging tools 1 is narrow, the mold members W are in contact with each other, and it is absolutely necessary to use one or two hanging tools 1 or change the interval pitch between the hanging tools 1. Therefore, productivity and workability can be greatly improved.

  Also, when a wide and thin aluminum mold W is transported to each treatment tank by the transport frame, the aluminum mold W is suspended in a state where the width surface is parallel to the transport direction. As a result of almost no vibration due to air resistance inside, when immersed in each treatment tank, the wide and thin mold material W collides with the inner wall of the treatment tank, and the mold material W itself is deformed. As a result, there is no concern about the occurrence of defective surface treatment, and the aluminum mold W being conveyed can be immediately lowered in each treatment tank. As a result, the treatment efficiency is significantly improved as compared with the conventional case.

  In the above-described embodiment, the auxiliary jig 11 held by one hanging tool 1 has only a function of hanging one aluminum mold W. For example, as shown in FIG. If a similar mechanism is provided on the free end edge side of the overhanging piece 18 so that two aluminum mold members W can be suspended, two aluminum mold members W can be attached to one hanging tool 1. Since it is suspended, the processing efficiency is further improved.

  The suspension apparatus according to the present invention is particularly suitable as a suspension apparatus for suspending a large number of aluminum molds on a conveyance frame, particularly when a wide and thin aluminum mold is anodized.
