Description

[Detailed description of the invention] "Industrial application field" The present invention is applied to a transport frame that conveys the surface-treated materials to each treatment tank in an anodizing treatment apparatus for aluminum materials, for example. The present invention relates to an improvement in a hanging member that removably suspends a support frame that supports processing material.

``Prior art'' As an example of a conventional hanging member of this type,
- There is one shown in Publication No. 42447.

In view of the shortcomings of the conventional fixed suspension method, this conventional suspension member allows the support frame to be detachably suspended from the transport frame. As shown, an insertion passage 4 passing vertically is defined inside the insertion passage 4, and a spring 5 is disposed inside the insertion passage 4.
Attachment fittings 7 are attached to both ends of the transport frame 1, which has a box shape and moves in a predetermined direction via a drive device, to which a lock lever 6, which projects its working end 6a, is rotatably pivoted by a biasing force. It is configured to be fixed through the

Note that the two support frames 2, 2 suspended via the hanging member 3 have the hanging member 3 attached to each upper end.
An engagement recess 8 that engages with the working end 6a of the lock lever 6 is formed in the insertion passage 4, and the lock lever 6 is disengaged by resisting the biasing force of the spring 5 immediately below the engagement recess 8. A protrusion 9 is provided that releases from the biasing force of the spring 5 at a predetermined position while rotating in the direction.

When the two support frames 2, 2 supporting a large number of surface-treated materials W in a horizontal position are suspended from the transport frame 1, each support frame 2 is suspended as shown in FIGS. 5A and 5B. The upper end portions are inserted from below into the insertion passages 4 of the hanging members 3 fixed to both ends of the transport frame 1, and the engaging recesses 8 are inserted into the operating ends 6a of the lock levers 6, respectively.
By engaging with the two support frames 2, 2 are suspended from both ends of the transport frame 1.

Conversely, when removing the support frame 2 from the transport frame 1 in order to remove the processed material W from the support frame 2, as shown in FIGS. 6A and 6B, two support frames 2, 2 are used. further linearly upward, and by the action of the projection 9, the lock lever 6 is rotated in the disengagement direction to a position where it is released from the biasing force of the spring 5, and the support frame 2 is removed from the insertion passage 4. By allowing the two support frames 2, 2 to fall, the transport frame 1
It becomes possible to remove it from the

"Problems to be Solved by the Invention" However, in such a conventional hanging member 3, the structure in which the support frame 2 is inserted into and removed from its own insertion passage 4 is difficult to ensure smooth insertion and removal. So, inevitably support frame 2
Since it is necessary to form a gap S to some extent between the circumferential surface of the suspension member 3 and the inner wall surface of the hanging member 3 that defines the insertion passage 4, the two Not only will the supporting frames 2, 2 inadvertently wobble, making the support of the surface-treated material W unstable, but the existence of the gap S will especially cause the hanging member 3 and the supporting frame 2 to be moved from the conveying frame 1 side. As a result, the energization state of each material W to be surface-treated is significantly impaired, and it is fully conceivable that the electrolytic treatment of the material W to be surface-treated may be adversely affected in the end.

Moreover, since the support frames 2 that are actually used have considerable variations in their width dimensions, the wider the gap S becomes, the more serious the problem becomes due to the dimensional variations.

In addition, when using the conventional hanging member 3, a lock lever 6 on the hanging member 3 side is attached to the upper end of the support frame 2.
Since it is necessary to form an engagement recess 8 that engages with the working end 6a of the lock lever 6 and to provide a protrusion 9 that rotates the lock lever 6 in the direction of disengaging the lock lever 6 against the spring 5, it is necessary to In addition to increasing the number of machining steps, this machining requires high precision to obtain synchronous engagement and rotation, which makes the machining process extremely difficult and increases costs. Ta.

"Means for Solving the Problems" The hanging member of the present invention was developed to effectively solve the above-mentioned conventional problems. At least the hanging part has a box shape defining an insertion space into which the upper end of the support frame is inserted, and has three guide elongated holes bored in the vertical direction of the opposing side plates, Both ends of a pressing member having a pressing portion for pressing the support frame within the insertion space and a through hole for inserting the end side of the leaf spring are inserted into the upper and lower middle guide long holes, respectively. , fitting both ends of a movable member having a through hole through which the center portion of the leaf spring is inserted into the intermediate guide elongated hole; The appropriate position of the operating lever and the movable member are connected by a link, and when the operating lever is rotated, the movable member is moved via the link using the elongated guide hole as a guide, and the through hole of the movable member and both presses are moved. A configuration was adopted in which the two pressing members are moved in the pressing direction and the pressing release direction with respect to the support frame using the guide elongated holes as guides by deforming and restoring the leaf springs inserted into each through hole of the member.

"Operation" Accordingly, in the present invention, a state is obtained in which the hanging member is fixed to both ends of the conveyance frame via the fixing part,
After inserting the upper end of each support frame into the insertion space of the suspension part, the operation lever is rotated to move the movable member using the guide elongated hole as a guide by the action of the link, and the through hole of the movable member is moved. When the central part of the leaf spring inserted inside is deformed, the deformation of the leaf spring causes
The upper and lower pressing members move in the pressing direction using the guide elongated holes as guides, and elastically press the upper end of the support frame with their respective pressing parts, so that the two support frames are reliably suspended on the transport frame. It will be lowered.

Also, when the operating lever is rotated in the opposite direction, the moving member moves in the direction of releasing the deformation of the leaf spring due to the action of the link, and at the same time, the restoring force of the leaf spring causes the two pressing forces to be released. Since the member automatically moves in the pressure release direction, it becomes possible to easily remove the support frame from the conveyance frame.

``Example'' Hereinafter, the present invention will be described in detail based on an example illustrating the present invention.The hanging member according to this example also has two suspension members that support the surface-treated material in a horizontal position, as in the conventional case. It was developed as a hanging member that removably suspends the support frame from both ends of the transport frame, but its unique feature is that the support frame can be suspended without any conventional processing. The point is that it can be removably suspended from the transport frame as it is.

To explain this specifically, the hanging member 13 of this embodiment has a box shape assembled from two substrates 14, 14 and two side plates 15, 15, as shown in FIGS. 1A and 1B. It consists of an upper fixing part 13A for the transport frame 11 and a lower hanging part 13B for the support frame 12.

As shown in the figure, the fixing part 13A of the transport frame 11 is composed of only two boards 14, 14, and each board 14 holds both sides of the transport frame 11, and the upper end is fixed to a plurality of bolts and nuts. 16, the hanging member 13 itself is fixed to both ends of the transport frame 11, and one of the fastening bolts is attached to a trapezoidal block body 17a and a triangular block body whose base is upward. 17b, 17b are fitted,
By tightening the bolts, each block body is moved, and the central trapezoidal block body 17a is moved to the transport frame 11.
By pressing against the lower hanging part 13B side,
The suspension member 13 itself is configured to be securely fixed not only to the side portions of the transport frame 11 but also to the upper and lower portions thereof.

Further, the hanging portion 13B of the support frame 12, which does not require any processing, is composed of the two boards 14, 14 and two side plates 15, 15 provided between the boards 14, and has internal support. Insertion space 18a of frame 12
and a storage space 18b for storing a pressing member and a moving member to be described later, and the two side plates 1
Three opposing guide slots 19a, 19b, and 19c are formed in the vertical direction of 5 and 15, respectively, and the upper and lower guide slots 19a and 19c are provided with the following holes. Both ends of the pressing member 20 are movably inserted into the intermediate guide elongated hole 19b.
Inside, both ends of the moving member 21 described below are movably fitted.

The former pressing member 20 has a rectangular shape, and as shown in FIG. 2, has one end serving as a pressing portion 20a for pressing the support frame 12 within the insertion space 18a, and has a through hole 20b formed in the center. The end portion of the leaf spring 22 is inserted into the through hole 20b in a manner that prevents it from coming off. In addition, as an example of the removal prevention means,
As shown in the figure, a notch 22a is provided at the end of the leaf spring 22.
, and a pin 23 is interposed within the notch 22a. . Furthermore, the edge of the through hole 20b that comes into contact with the surface of the leaf spring 22 is formed into a pointed shape in order to reduce the contact area as much as possible.

On the other hand, the latter moving member 21 is
Unlike 0, it does not have a pressing part, but it has a shaft part 2 on the other end side.
1a rotatably supports the pressing roller 24, and the roller 24 on the other end side and the connecting portion 2 on the one end side.
A through hole 21b through which the center portion of the leaf spring 22 is inserted is formed between the holes 1c.

Furthermore, as shown in FIGS. 1 and 2, the hanging member 13 of this embodiment is provided with a shaft 26 supported by a bearing 25 on the outside of the substrate 14 on the side that defines the insertion space 18a. One end of a pair of operating levers 27 is fixed to both ends of the shaft 26, and the operating levers 27
A shaft 28 is provided at the intermediate portion of each operating lever 27, and a link is formed between the shaft 28 and the shaft portion 21a of the moving member 21 that rotatably supports the pressing roller 24. 29, and when the operation lever 27 is rotated above the extension line L of the shaft 26, the action of the link 29 accompanying the rotation operation moves the movable member 21 into the guide elongated hole 19.
b as a guide, move it in the direction of the insertion space 18a to connect the through hole 21b of the moving member 21 and both pressing members 2.
By deforming the leaf spring 22 inserted through the through hole 20b of 0 with the pressing roller 24, the leaf spring 2
In modification 2, when the pressing members 20, 20 are moved in the same direction, that is, in the pressing direction, and conversely, the operating lever 27 is rotated below the extension line L, the link 2
9 now acts in the opposite direction to move the moving member 21 to the leaf spring 2.
By moving the plate spring 22 in the direction of releasing the deformation of the plate spring 22 and releasing the deformation of the plate spring 22 by the pressing roller 24, the restoring force of the plate spring 22 automatically moves the two pressing members 20, 20 in the pressing release direction. It is configured to be moved.

Therefore, when suspending the support frame 12 from both ends of the conveyance frame 11 using the suspension members 13 having such a configuration, as shown in FIG. After the fixing portion 13A of the hanging member 13 is securely fixed to both ends of the transport frame 11 via the suspension members 17a and 17b, and the operating lever 27 is set below the extension line L, no processing is performed. When the upper end of the supporting frame 12 that is not open is inserted into the insertion space 18a of the hanging part 13B of the hanging member 13, and the operating lever 27 is rotated upward manually or mechanically as shown in FIG. With this operation, the link 29 acts to guide the movable member 21 through the guide elongated hole 19.
b is used as a guide in the direction of the insertion space 18a, and the center portion of the leaf spring 22 inserted into the through hole 21b of the moving member 21 is moved by the pressing roller 24.
Since the plate spring 2 is forcibly pressed and deformed,
2, the upper and lower guide elongated holes 19a, 19c
The pressing members 20, 20 fitted therein automatically move in the same direction and elastically press the upper end of the support frame 12 with their respective pressing parts 20a in cooperation with the inner surface of the substrate 14. .

As a result, the two support frames 12, 12 can be reliably and easily suspended from the transport frame 11.

Moreover, in such a suspended state, the support frame 12
is the leaf spring 2 in the insertion space 18a of the hanging part 13B.
Since it is pressed at the top and bottom by the two pressing members 20 with the pressing force obtained from the spring pressure of step 2, it is hung securely and there is no worry that it will wobble even if the transport frame 11 moves. Not only that, but each support frame 12 is always held in close contact with the inner surface of the substrate 14 by the spring pressure, and no unnecessary gaps are formed between the two, so the energized state is also excellent. Becomes good.

Furthermore, even if there is variation in the width of the support frame 12, such variation can be effectively absorbed by the spring pressure of the leaf spring 22, so that there is no problem with the suspended state.

Next, when removing the support frame 12 from the transport frame 11, if the operating lever 27 is rotated below the extension line L, the link 29 will act in the opposite direction and move the moving member 21 in the opposite direction. Since the deformation of the leaf spring 22 caused by the pressing roller 24 is released by moving the leaf spring 22 in the direction, the restoring force of the leaf spring 22 causes the two pressing members 2
0 and 20 are also automatically moved in the direction of release of the pressure while releasing the elastic pressure state against the support frame 12 using the guide elongated holes 19a and 19c as guides, thereby opening the insertion space 18a.

As a result, the support frame 12 can be easily removed from the transport frame 11. Therefore, such a removal operation is a reverse process of FIGS. 3A and 3B showing the above-mentioned hanging operation.

Furthermore, in the above embodiment, the upper and lower pressing members 20 that press the support frame 12 may be integrally molded from an insulating material such as plastic or ceramics, or at least only the pressing portion 20a may be molded from the insulating material. For example, since it is possible to prevent the support frame 12 from being energized from the pressing member 20 side, the pressing member 20 may generate heat due to unnecessary energization, and the pressing member 20 may
It is possible to effectively prevent sparks from being generated from a and damaging the pressing portion 20a itself or deteriorating the elasticity of the leaf spring 22.

In addition, when the support frame 12 is made of copper, the substrate 14 and side plate 15 of the hanging member 13 are also made of copper,
If it is aluminum, it is aluminum, and both are 12,1.
If 3 are made of the same metal material, even if they come into sliding contact during insertion and removal, the soft aluminum will adhere to the hard copper surface, as in the case where one is made of copper and the other is made of aluminum. , by generating an insulating film on the surface of copper,
It is also possible to effectively prevent a decrease in electrical conductivity.

Furthermore, as shown in FIG. 3, a packing material 31 made of an elastic material such as silicone rubber or soft Teflon is attached via a groove 30 to a suitable position on the inner surface of the substrate 14 to which the support frame 12 is elastically attached. For example, it is possible to prevent the processing liquid from entering between the inner surface of the substrate 14 and the support frame 12 during processing and deteriorating the inner surface of the substrate 14, that is, the power supply surface.

"Effects of the Invention" As described above, the hanging member of the present invention consists of a fixing part to the transport frame and a hanging part to the support frame.
Of the three long guide holes drilled in the vertical direction of the side plate of the hanging part, both ends of the pressing member are fitted into the upper and lower guide long holes, respectively, and both sides of the moving member are inserted into the middle guide long hole. One end of the operating lever is fitted in the other end, and one end of the operating lever is rotatably pivoted to an appropriate external location, and the operating lever and the moving member are connected by a link, and the link moves as the operating lever rotates. By moving the member in a predetermined direction, the leaf springs inserted into the through hole of the moving member and the through holes of both pressing members are deformed and restored, and the two pressing members are guided by the guide elongated holes. Since it is characterized by moving the support frame in the pressing direction and the pressing release direction, in particular, the suspended support frame has two springs obtained from the spring pressure of the leaf spring in the insertion space of the hanging part. Because the pressing force of the pressing member presses elastically at the top and bottom, there is no need to worry about the support frame wobbling during transportation, unlike in the past, and each support frame always maintains the insertion space due to spring pressure. It will be suspended in close contact with the inner surface of the hanging portion that defines it.

Therefore, unlike the conventional method, unnecessary gaps are not created at all, so that the current conduction state is extremely good, and there is no adverse effect on the electrolytic treatment of the material to be surface treated.

This also means that even if there is variation in the width of the support frame, such variation can be effectively absorbed by the spring pressure of the leaf spring, so from this point of view,
There is no longer any problem with the hanging condition.

Furthermore, with the suspension member of the present invention, there is no need for complicated machining of the support frame that requires precision as in conventional methods, which reduces the number of machining steps and greatly contributes to cost reduction. It also means that you can do it.
