Description

[Detailed Description of the Invention] The present invention provides a method for suspending a large number of surface-treated materials in a surface treatment apparatus (for example, an anodizing treatment apparatus for aluminum profiles) in which a large number of surface-treated materials are suspended from a conveyor frame. The present invention relates to an end holding device that holds the free lower ends of each other at a predetermined interval.

In conventional hanging type surface treatment equipment of this kind, the upper end of the material to be surface treated is generally simply attached to the conveyor frame at regular intervals using a dedicated hanging tool or other hanging structure. Since the lower end was placed in a completely free state, the material during conveyance was always in a state of swinging largely independently in the front-rear direction and left-right direction around the hanging point.

Therefore, if the materials swing independently and irregularly due to such vibration, especially in the left-right direction, that is, in the direction of adjacent materials, adjacent materials or several materials may come into contact with each other, causing damage to the bare surface before surface treatment. After treatment, damage to the treated surface is caused, and if adjacent materials or several materials are shaken and tangled during solution immersion or electrolysis, it may lead to defective surface treatment.

The present invention was devised in view of these conventional drawbacks, and it is attached to the free lower ends of the suspended materials to be surface treated, and the lower ends of adjacent materials are spaced apart from each other by a predetermined distance. It is an object of the present invention to effectively solve each of the above-mentioned drawbacks by providing a device that allows holding.

Hereinafter, the present invention will be described in detail based on illustrative embodiments.
The end holding device according to the present invention includes a clip body 1 that clamps the free lower end of the material to be surface treated using its own elasticity, and a desired length having a considerable number of attachment means for the clip body 1 in the longitudinal direction. It consists of a connecting member 2 with dimensions.

The entire structure of the clip body 1 is made of a metal material having inherent corrosion resistance, other metal material treated with corrosion resistance, or synthetic resin material, and specifically, as shown in FIGS. 1 has a substantially ■-shaped (including U-shaped) shape with elasticity when opened, and a large hole 5 corresponds to the large hole 5 in one side piece 3 forming the ■-shaped shape of the clip body 1, and the large hole 5 corresponds to the large hole 5 in the other side piece 4. A regulating plate 7, which will be described later, is provided in both holes 5 and 6.
The structure is such that the elasticity of the clip body 1 is restricted by being hooked.

Specifically, the horizontal U-shaped bent end 7a of the regulating plate 7, which is engaged from the outside of the negative side piece 3, is attached to the base end of the substantially dogleg-shaped operating lever 8 in the large hole 5 of the negative side piece 3. Loosely insert into the small hole 6 of the other side piece 4
The other L-shaped bent end 7b of the regulating plate 7 is locked to regulate the elasticity of the clip body 1.

Therefore, the one side piece 3 of the clip body 1 is pressed toward the other side piece 4 by the operation of the operating lever 8, and the clip body 1 is urged in the closing direction against its own elasticity.

Moreover, the clip body 1 has a holding claw 9 extending linearly in the center of the end of one side piece 3, and base parts 10 on both sides of the end of the other side piece 4.
a is bent in the direction of the clamping claws 9, and two pronged clamping claws 10, 10 are provided in series, respectively, extending in parallel in the same direction near the outside of the clamping claws 9, and both clamping claws 9, 10 are always clamped. This is a configuration that biases the state.

Therefore, when the clip body 1 is biased in the closing direction by operating the operating lever 8 as shown in FIG. 2A, both the clamping claws 9 and 10 become open, and when this state is obtained, the state shown in FIG. 2B occurs. As shown, the free lower end 11a of the surface-treated material 11 is held by both clamping claws 9,
10, the clip body 1 is attached to the lower end portion 11a.

Particularly, in such an attached state, all the elasticity of the clip body 1 is transmitted as the clamping force of the clamping claws 9 and 10, and the other clamping claw 10 and 10 are held together by two prongs from both sides of one clamping claw 9. Because it is something to be held between the two, even if it is relatively small, the material 1
It is securely attached to the lower end portion 11a of the device 1, and there is no fear that it will accidentally fall off due to vibration or its own weight.

Furthermore, when the clip body 1 including the clamping claws 9 and 10 is made of a metal material, at least the clamping claws 9
, 10. Not only the clamping surfaces of 10 but also the portions in contact with the lower end of the material 11 shall be treated with Teflon coating, ceramic coating, or other treatment to ensure insulation. Both clamping claws 9, 1
Teflon coating 12 is applied to the required area of 0.10.

On the other hand, the connecting member 2 is made of a wire rod having a desired length as shown in FIG. Either a considerable number of attachment arms 13a are provided, and the clip body 1 having the above structure is attached and connected to each attachment arm 13a in the state shown in the figure, or a structure with a desired length dimension as shown in FIG. 3B is adopted. It is constructed of a plate material, and a considerable number of mounting holes 13b serving as mounting means are bored in the plate material at similar intervals, and the clip body 1 is attached to each of the mounting holes 13b via a pin 14 in the state shown in the figure. or as shown in FIG.
A tip stopper 16 provided at the lower part of the clip body 1 for each attachment ring 13C.
A mounting rod 15 is loosely inserted to attach and connect the clip bodies 1 in the respective states shown in the drawings.

Therefore, regardless of the structure of the connecting member 2 described above, each clip body 1 connected to the connecting member 2 at a predetermined interval can be suspended from the transport frame 17 as shown in FIG. Free lower end portions 11 of a large number of surface-treated materials 11
When the clamping claws 9, 10, 10 are clamped and attached to the clamping claws 9, 10, 10, the free lower end 11a of each material 11 is maintained at a predetermined distance by the attachment of each clip body 1 connected to the connecting member 2. Therefore, even if the material 11 swings back and forth and left and right around the hanging point during transportation, the material 11
1 only operate in conjunction with each other while maintaining a constant spacing, so there is no fear that they may swing independently and irregularly and come into contact, unlike in the past.

In addition, no matter which of the connecting members 2 shown in FIG. Even if there is a difference in length between the materials 11, there is an advantage that the play can easily absorb the difference in length.

Furthermore, since 150 to 200 pieces of material 11 are normally suspended from the conveyance frame 17, the length of the negative connecting member 2 is approximately 30 to 50 mm.
Set the dimensions to the extent that 0 clip bodies 1 can be connected,
It is much more convenient in terms of workability to use the - connecting members 2 arranged in a continuous manner.

Furthermore, the feature of the end holding device according to the present invention is that the clamping force of both clip bodies 1, 1 connected to the extreme ends of the negative connecting member 20 of the length dimension is The point is that the clamping force is larger than that of the clip body 1 connected at the intermediate position.

Specifically, as shown in FIG. 5, a clamping needle 18 made of titanium, for example, is attached to each clamping surface of each clamping claw 9, 10, 10 of the clip body configured as shown in FIGS. 1A and 1B. 9.10
．． 10 and the Teflon coating 12, etc., in an insulated state, and the free lower end 11a of the material 11 is strongly clamped by the clamping claws 9.degree. 10.10 with the clamping needle 18.

Therefore, the - connecting member 2 is at least only the reinforcing clip bodies 1, 1 at both ends, and the free lower end 11 a of the material 11.
Since it is possible to suspend horizontally downward, the clamping force of the clip body 1 connected at an intermediate position other than the reinforced clip bodies 1, 1 at both ends can be minimized, and a reflective effect can be achieved. At the same time, by simply removing only the reinforced clip bodies 1゜1 at both ends from the material 11, each clip body 1 at the middle position can be removed.
It becomes possible to simultaneously and automatically remove the clips without having to remove them one by one, and it is possible to save labor in removing at least 30 to 50 clip bodies connected to the negative connecting member 2.

6A and 6B show other examples of the clip body, and the clip body 21 is constructed as a whole into a U-shape having elasticity in the closing direction, and the inner surfaces of the negative side piece 23 and the other side piece 24 are Opening levers 28.28 are installed horizontally and extend parallel to each other in opposite directions through holes 25.26 drilled in the other side, and when both opening levers 28.28 are pressed, the tip clamping portion 29.30 is opened. When the clip body 21 is connected to the connecting member 2 at a constant interval, the third
It is assumed that connections are made based on the principles shown in Figures A, B, and C.

In addition, when the clip body 21 is connected to the extreme end of the connecting member 2, if the clip body 21 is made of a synthetic resin material, the titanium clamping part 29, 30 can be directly connected to the clamping part 29, 30 as shown in FIG. 6A. If the needle 18 is attached and made of a metal material, it is attached while being insulated with a Teflon coating 12 or the like as shown in FIG. 6B.

In particular, when it is made of a synthetic resin material, it is optional to use a saw or groove instead of the needle 18 to strengthen the clamping force depending on the implementation.

Therefore, the present invention provides a new device for holding the free lower ends of the surface-treated materials suspended in a transport frame at a predetermined interval, so that the flat ends of adjacent materials are The appropriate spacing is always maintained during suspension, and independent swings in the longitudinal and lateral directions can be effectively prevented.

Therefore, even if the material shakes during conveyance, the lower end of the material only moves in a state where the distance is always maintained.
Conventionally, adjacent materials or several materials come into contact with each other, causing damage to the bare surface before surface treatment and damage to the treated surface after treatment, or causing defective surface treatment during treatment. It can be completely wiped out.

Furthermore, the present invention is characterized by a configuration in which the clamping force of the clip body connected at the extreme end of the connecting member is greater than that of the clip body at the intermediate position, so that the clamping force of the clip body at the intermediate position can be reduced. This makes it possible to significantly reduce the size of the clip body, greatly contributing to the miniaturization and simplification of the clip body, as well as strengthening the clamping force.By simply removing the lower end of the material of the clip body, it is also easy to remove the intermediate clip body. This can greatly contribute to improving work efficiency.
