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. This invention relates to a clip that holds the free lower ends of the clips at a constant distance.

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 was always in a state of swinging largely independently in the front-rear direction and left-right direction around the hanging point during conveyance.

For this reason, if the material swings 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 surface before surface treatment, but not after surface treatment. In addition to causing damage to the treated surface, if adjacent materials or several materials are shaken and tangled with each other during solution immersion or electrolytic treatment, it may also lead to defective surface treatment.

Therefore, the present invention was devised in view of such conventional drawbacks, and it is attached to the free lower ends of the suspended materials to be surface treated to hold the lower ends of adjacent materials at a constant distance. By providing a clip that enables the above-mentioned problems to be effectively solved.

The clip according to the present invention will be described in detail below based on one embodiment illustrating the present invention. Specifically, as shown in FIGS. 1A and 1H, the clip main body 1 has an elastic approximately V-shape (including a U-shape), and one side of the main body 1 forming the ■-shape By drilling a large hole 2 in one side 1a and a small hole 3 corresponding to the large hole 2 in the other side 1b, and hooking a regulation plate 4, which will be described later, to both holes 2 and 3, the main body 1 itself It is a configuration that regulates the elasticity of.

Specifically, the horizontal U-shaped bent end 4a of the regulating plate 4, which is engaged from the outside of the - side piece 1a, is attached to the base end of the approximately dogleg-shaped operating lever 5 in the large hole 2 of the - side piece 1a. One end 4a is loosely inserted and the L-shaped bent other end 4b of the regulating plate 4 is engaged with the small hole 3 of the other side piece 1b, and the other end 4b of the regulating plate 4 is engaged with the base end of the operating lever 5. The structure is such that the elasticity of the main body 1 is restricted.

Therefore, when the main body 1 is operated by the lever action of the operating lever 5, the one side piece 1a is pressed toward the other side piece 1b, and the main body 1 is urged in the closing direction against its own elasticity.

Further, a linearly extending clamping claw 6 is provided in the center of the end of the working piece 1a of the main body 1, and a base 7a is bent in the direction of the clamping claw 6 on both sides of the end of the other side piece 1b. Two clamping claws 7, 7 extending parallel to each other in the same direction are provided in the vicinity of the outer side of the clamping claws 6, respectively, and the two clamping claws 6, 7 are always biased into a clamping state.

Therefore, when the main body 1 is biased in the closing direction by operating the actuating lever 5 as shown in FIG. 2A, both the gripping claws 6 and 7 become open, and this state is obtained as shown in FIG. 2B. By clamping the free lower end 8a of the material 8 to be surface treated between the clamping claws 6 and 7, the clip body 1 is attached to the lower end 8a of the material 8.

In particular, in such an attached state, all the elasticity of the main body 1 is transmitted as the clamping force of the clamping claws 6, 7, and the other clamping claws 7, 7 are held in place by two prongs from both sides of one clamping claw 6. Since it is used to hold the material 8, even if it is relatively small, the lower end 8a of the material 8
It is securely attached to the machine, and there is no risk of it falling off accidentally due to vibration or its own weight.

In addition, when the main body 1 including the clamping claws 6 and 7 is made of a metal material, at least the clamping claws 6 should be , 7.7 as well as the lower end 8a of the material 8.
Teflon coating, ceramic coating, or other treatment is applied to the parts that come into contact with the gripping claws 6 to ensure insulation.
, 7, a Teflon coating 9 is applied to the necessary areas.

Furthermore, a feature of the clip according to the present invention is that the clip bodies 1 having the above structure are connected to each other by a spacing maintaining means that maintains a constant spacing.

In such a connection structure, the distance maintaining means is configured separately from the clip main body 1, and the clip main body 1 is connected to the separate distance maintaining means at a constant interval, or the clip main body 1 itself is connected. A connecting means that also serves to maintain the distance is attached to the clip body 1, and the means clip bodies 1 are directly connected to each other at a constant distance.

In the following, each embodiment will be described in detail. First, in the former case, as shown in FIG. A considerable number of U-shaped attachment arms 10a are provided at intervals corresponding to the distances shown in FIG. As shown in the figure, a considerable number of mounting holes 11a are similarly drilled at regular intervals in the plate material 11 serving as the spacing means A, and the clip body 1 is inserted through a pin 12 in each of the mounting holes 11a as shown in the figure. Alternatively, as shown in FIG. 3C, a considerable number of attachment rings 13a are arranged at regular intervals on the wire rod 13 serving as the spacing means A, and the clip body 1 is attached to the bottom of each attachment ring 13a. provided tip stopper 14
The configuration is such that the attachment rod 14 with a is inserted loosely and attached and connected in the state shown in the figure.

In each of the above embodiments, as shown in FIG. If the clamping claws 6, 7.7 are clamped and attached to the free lower end 8a of each material 8, the free lower end 8a of each material 8
Since the distance between the materials 8 is maintained by attaching the clip body 1, even if the materials 8 swing back and forth and left and right around the hanging point during transportation, the materials 8 will always be kept at a constant distance from each other. Since they only interlock in the same state, there is no need to worry about each of them swinging independently and irregularly and coming into contact as in the past.

Furthermore, when each clip main body 1 is attached and connected using a separate spacing maintaining means A, play occurs in the vertical direction when the means A and the clip main body 1 are attached. Even if there is a difference in length, there is an advantage that the play can easily absorb the difference in length.

In addition, in the latter embodiment, the clip body 1 itself is provided with a connecting means B that also serves to maintain the distance, as shown in FIG. A protruding arm 16 having a diameter of 1.a and an insertion hole 17 that engages with the bent portion 16a.A protruding arm 17 having a diameter of 17a that engages with the bent portion 16a is integrally attached to the main body 1 in opposite directions, and the opposing protrusions of adjacent clip main bodies 1 are provided. By engaging the bent portion 16a of the arm 16.17 with the insertion hole 17a, the clip body 1 is continuously and directly placed in the state shown at a constant interval formed by both the protruding arms 16.17. Alternatively, as shown in FIG. 5B, a rod 18 having a bent portion 18a at one end and an insertion hole 18b at the other end serving as the connecting means B is connected to both ends 18a, 1.
8b protrudes from both sides, and is fixed to the lower part of the clip body 1, and by engaging the opposing bent portions 18a of adjacent clip bodies 1 with the engagement holes 18b, the clip bodies 1 can be made in the same manner. The clip main body 1 may be connected with an interval formed by the rods 18 as shown in the figure, or as shown in FIG. Different upper and lower slits 19a
, 20a are integrally attached to the main body 1 in opposite directions, and the slits 19a and 20a of the opposing projecting arms 19,20 of adjacent slip main bodies 1 are engaged from above and below. By doing so, the clip main body 1 is directly connected to the state shown in the figure with a gap formed by both projecting arms 19 and 20.

In the above embodiments, as in the former embodiment, the grip main body 1 is attached in advance to the free lower end portions 8a of a large number of surface-treated materials 8 suspended from a transport frame 15 as shown in FIG. At the same time as the clamping claws 6, 7.7 are secured and attached, the clip bodies 1 are successively connected to each other by the connecting means B, so that the free lower end 8a of each material 8 can maintain the spacing attached to the clip body 1. Since the spacing is maintained by the dual-purpose connecting means B, even if the materials 8 swing back and forth and left and right around the hanging point during transportation, the materials 8 are always kept at a constant distance from each other. Since they only work in conjunction with each other, there is no need to worry about them swinging independently and irregularly and coming into contact as in the past.

In any of the embodiments, if it is desired to strengthen the clamping force of the clip, each clamping claw 6, 7,
It is also optional, depending on the implementation, to provide a clamping needle 21 made of titanium, for example, in an insulated state on the clamping surface of 7.

Therefore, the present invention can be attached to the free lower ends of a large number of surface-treated materials suspended in a transport frame, and it is possible to hold the lower ends of adjacent materials at a constant distance. Since the clip is provided, it is only necessary to attach the clip to each free lower end of the material, so that the flat ends of adjacent materials are always kept at a corresponding distance from each other during suspension.
It is possible to effectively prevent individual swings in the longitudinal and lateral directions.

Therefore, even if the material shakes during conveyance, the lower end of the material always moves in a state where the distance is maintained, so that adjacent materials or several pieces of material come into contact with each other and the surface It has become possible to completely eliminate defects that cause damage to the surface before treatment and damage to the treated surface after treatment, as well as induce defective surface treatment during treatment.
