Description

[Detailed Description of the Invention] (Industrial Application Field) This invention mainly involves suspending a long material such as an aluminum extruded shape from a suspension body that also serves as a power supply bar to perform processes such as a degreasing process, a water washing process, an electrolytic process, etc. The present invention relates to a long material vertical hanging device that vertically suspends and supplies a large number of long materials to a surface treatment device that sequentially moves to each surface treatment process to perform surface treatment.

(Prior art) Conventionally, when applying surface treatment such as anodic oxidation coating treatment to a long material such as an extruded aluminum shape, a series of processes such as a degreasing process, a water washing process, an etching process, or an anodizing process are performed. A number of treatment tanks are installed in parallel, and a crane is installed to transport the long materials through each treatment process and to immerse them in each treatment tank, and this crane is used to support a large number of long materials horizontally. The so-called horizontal suspension method is well known, but since the long material is supported at both ends, it has the disadvantage that contact marks remain on both ends of the long material that correspond to the supporting parts, and there is a risk of liquid shortage in the processing tank. Because of this, a large amount of liquid is taken out, which is extremely uneconomical due to the amount of liquid consumed.The process liquid taken out also has the disadvantage of contaminating the treatment liquid in the next process as an impurity. It is.

(Problems to be Solved by the Invention) In order to solve these drawbacks, a method has been proposed in which long materials are hung vertically. suspended below a suspension body equipped with an electrode rod,
In order to suspend and transport long items, the suspension body must be held at a high location above.
There is no suitable means for efficiently and reliably suspending a large number of long materials from such suspension bodies, and this has been a major impediment to the realization of a mass production system using vertical suspension.

Therefore, in view of the fact that a surface treatment method using a vertical hanging method is extremely useful industrially, an object of the present invention is to provide a vertical hanging device for long materials suitable for mass production in order to realize this method. As,
In particular, we applied unique ingenuity in how to solve the complexity, inefficiency, unreliability, and operational danger of suspending a large number of long materials from suspension bodies held high above. It is elaborate.

(Means for Solving the Problems) That is, the present invention provides a suspension body for locking a long material to one end of the hoisting frame that reciprocates between the floor-side work area and an upper high place. A support part is provided that supports the body in a non-rotatable and removable manner, and a support body for supporting the elongated material secured to the suspension body is installed horizontally below the support part, and A guide for reciprocating the support part side of the collapsible frame body is provided between the floor-side work area and the upper high place.

(Function) Since the present invention has the above-mentioned configuration, after lowering the empty suspension bodies to the floor-side work area, arranging them parallel to each other and in a horizontal state, and locking one end to the suspension body,
By raising a large number of long materials together with this suspension body guided by a guide and raising them to a high place, horizontal long materials can be suspended vertically at once, and such work can be carried out. This is done safely and reliably.

(Example) In explaining the present invention in detail with reference to the embodiment shown in the drawings, the explanation will be made in relation to a surface treatment apparatus used in carrying out the present invention. Although not shown in the drawings, the surface treatment equipment here has a series of processing tanks necessary for surface treatments such as degreasing, washing, etching, and electrolysis arranged in parallel as described above, and a long material is suspended across each processing tank. It is equipped with a crane to transport the suspended suspension body and to immerse long materials into each treatment tank. Basically, it is no different from the conventional horizontally suspended surface treatment equipment, but the first On the long material supply side of the surface treatment apparatus as shown in the figure (i.e., the right half of FIG. In consideration of the possibility that there would be a discrepancy between the rotation program of the lifting frame body A, the crane travel and the rotation of the frame body A should be carried out smoothly and reliably, and the flow of surface treatment work would be hindered. In order to prevent
A support shelf for temporarily storing empty suspension bodies B without elongated material 4 is provided at an appropriate position.

And, this invention is an empty suspension body B from a high place above.
The hoisting frame body A is used to transport the material to the floor-side workshop C and the suspension body B with the long material 4 locked thereon at the floor-side workshop C to the supply side. In this example, as shown in FIG. 2, the raising/lowering frame body A is composed of a base frame 7 and a support frame 11 mounted on the upper end of the base frame 7 so as to be vertically movable. is constructed by hanging a horizontal beam 27 between the vertical frames 26, 26a facing each other at a constant interval, and the vertical frames 26, 26a
A slider 8 that fits into and engages with the inner surfaces of the pair of opposing guides 5 is provided at the upper end E (the slider on one vertical frame 26 is omitted). A pair of opposing guides 5 (the guide on the opposite side is hidden and cannot be seen) is
Floor side 6 on the long material supply side of the surface treatment device
The tip portion 24 erected in the workshop C is connected near a high place above the supply side.

Therefore, the vertical frames 26, 26a of the raising/lowering frame body A are raised to a higher place above the floor-side work area C along the pair of guides 5, and the drive for raising and lowering them is the first one. As illustrated in the figure, a chain 10 is stretched between an electric motor 9 fixed at a high place above and a sprocket 28 provided at the base end of the guide 5.
This can be achieved by making it possible to go around the guide 5 and by tying both ends to both sides of the slider 8.

By the way, the suspension body B for locking the long material 4
The arm body part 3 is provided with arm body parts 39, 39a that protrude obliquely upward on both sides of the body part 3 that is long in the transverse direction.
Hook parts 19, 19 are provided horizontally at the ends of the parts 9, 39a for being supported at a high place above, and the lower part of the body part 3 has an electrode rod 18 suspended horizontally. .

A support part D for supporting the suspension body B in a parallel state to the raising/lowering frame body A, non-rotatably and detachably, is provided at the upper end of the support frame 11. Reference numeral 11 denotes a groove 2 provided on the opposing inner surfaces of the vertical frames 26, 26a of the base frame 7.
Arms 12, 12 that horizontally support the suspension body B are mounted on the upper ends of the movable frames 30, 30a fitted in the movable frames 30, 29a.
protruding toward the surface treatment device, and the front portions of the arms 12, 12 are provided with groove-shaped locks for locking the tip hook portions 19, 19 of the suspension body B. parts 38, 38 are provided, and this arm 1
A support plate 13 is protruded below 2 and 12 to support the body portion 3 of the suspension body B and hold the suspension body B parallel to the raising/lowering frame body A. The locking parts 38, 38 constitute the support part D of the suspension body B, and thereby, the suspension body B maintains a certain distance with respect to the tilting frame body A when raising the tilting frame body A. They remain parallel when placed apart, are non-rotatably supported, and are removably locked.

In addition, in this support frame 11, at a position below the support part D consisting of the support plate 13 and the locking parts 38, 38, there is a long member 4 that is locked to the suspension body B as described later.
is caused when the raising/lowering frame body A is raised,
A support body E for supporting a large number of long materials 4 is mounted on the horizontal beams 31 and 3 so that they can be vertically suspended reliably and quickly without swinging or falling off the suspension body B.
It is provided as 1a so as to span between movable frames 30, 30a.

Therefore, the support portion D is provided at a position offset from the surface of the support body E by a distance protruding from the support frame 11, and the suspension body B is supported while being separated from the support frame 11. Therefore, when the raising and collapsing frame body A stands upright, the elongated member 4 locked to the suspension body B is vertically suspended in a state separated from the surface of the support body E.

By the way, when locking the elongated material 4 to the suspension body B, a hanger 20 as shown in FIG.
The hanger 20 has a hook-shaped locking part 34 on the upper side for hooking on the electrode rod 18, and a fitting groove 35 on the lower part for swallowing the end of the long material 4. The set screw 21 is screwed into one leg 36 forming the fitting groove 35, and the end of the elongated material 4 is held between the leg 37 and the other leg 37. Reference numeral 17 in FIG. 1 is a table for making a large number of long materials 4 parallel to the hoisting frame body A in the laid down state and for placing them side by side in a horizontal condition. The elongated material 4 is provided to be located on the side part of the body A.
The end portion of the long material 4 placed on the table 17 in advance, that is, the suspension body B which has fallen sideways as will be described later. A hanger 20 is attached to the end corresponding to the electrode rod 18 .

Since this embodiment has the above-mentioned structure, by rotating the folding frame body A to the folded state,
After the suspension body B is conveyed from a high place above and laid down on its side, a large number of long materials 4 arranged in parallel and horizontally in advance are conveyed toward the tilting frame body A by a belt conveyor. Next, the hook-shaped locking portions 34 of the hanger 20 are hooked onto the electrode rods 18 of the suspension body B in order to lock them. After that, when the electric motor 9 is driven to raise the raising/lowering frame body A along the guide 5, the elongated material 4
The suspension body B, which has been locked, rises as if being raised together with the hoisting frame body A, and along with this, the long material 4 is also gradually lifted up, but this hoisting frame body A When the suspension body B is raised, the recessed groove-shaped locking portions 3 in the arms 12, 12 of the support frame 11
8, 38, and the body part 3 is supported by the support plate 13 in parallel with the tilting frame A, so not only will it not swing, but the suspension body itself will not come off the tilting frame A. The raising/lowering frame body A
The elongated material 4 is also supported by the guide 5, so it rises extremely stably, and the elongated material 4 is also supported by the horizontal bars 27, 31, 3 as the support E of the hoisting frame A.
Since it is supported by 1a, it rises stably without swinging, and there is no possibility that adjacent long pieces will collide with each other and get damaged, or that they will become unlatched to the suspension body B and fall off.

In this way, the suspension body B, which holds the elongated material 4 that is rising together with the tilting frame body A, stops at the upper end of the guide 5 at the same time as the tilting frame body A stops in an upright state.
4 and suspends the elongated material 4 in a vertically suspended state. When the hoisting frame body A stops, the groove-like locking portion 38 of the suspension body support portion D and the support plate 13 Since the tip is provided at a position offset from the surface of the support body E, when the hoisting frame body A and the suspension body B stop in an upright state, the large number of long pieces 4 move upward due to their inertia. As a result, the hanger and the electrode rod 18 try to swing around the locking part, but there is a certain distance between the vertically suspended long material 4 and the support E. Therefore, the swinging long material 4 can be prevented from colliding with the support body E.

Then, the suspension body B is placed at a high place above the supply side.
are intermittently sent to the left in FIG. .

As described above, the device according to the present invention includes a support portion for non-rotatably supporting the suspension body on the raising/lowering frame body that reciprocates between the upper high place and the floor-side work area,
Since a guide is provided to guide the hoisting frame, the suspension body does not swing at all during the hoisting process of the hoisting frame, and is transported extremely stably and reliably. Since the support body is placed horizontally on the frame to support the long material that is fixed to the suspension body, the long material does not swing at all during the raising process of the hoisting frame, and is extremely stable. It rises stably, and is effective in preventing adjacent long materials from colliding with each other and causing damage or falling off.Furthermore, the support section is located at a position offset from the surface of the support body. In particular, this invention has the effect of preventing the swinging elongated material from colliding with the support when the tilting frame rotates upward and stops in an upright state. A support part for non-rotatably and detachably supporting the suspension body in parallel with the raising/lowering frame body, a support body for supporting the elongated material, and a support part provided offset from the surface of the support body, and furthermore,
Guiding the hoisting device with a guide is an essential element in ensuring the vertical lifting of long materials while preventing the occurrence of defective products, preventing the occurrence of danger, and improving work efficiency. .

As mentioned above, on the long material supply side of the surface treatment equipment,
Although we have described a device for vertically suspending long materials, another big problem is how to remove surface-treated long materials from the suspension body while vertically suspended.
It can be said that the actual vertical hanging type surface treatment method cannot be completed unless this removal device is also implemented, and of course there has been no technical means that can solve this problem in the past.

The present invention also provides a means for solving this problem based on the above-described device for vertically suspending a long material. That is, on the long material removal side (left half in Figure 1) of the surface treatment device for removing long materials after surface treatment, a device that is exactly the same as the device that can realize the above-mentioned long material vertical hanging method is installed. It is installed and has a symmetrical effect with the equipment on the supply side. The empty suspension body B is then returned to the supply side.

In this way, the empty suspension body B returned to the long material supply side is again hung vertically with the long material 4 by the vertical hanging device of the present invention, and sequentially passes through the surface treatment device to the long material removal side. In the end, by repeating the vertical hanging process of long materials, the surface treatment process of long materials, and the process of removing long materials, it is possible to continuously perform vertical hanging type surface treatment. It is something that can be done.

(Effects of the Invention) As described above, in a vertically suspended surface treatment device that improves the drawbacks of vertically suspended surface treatment devices, it is possible to hold a suspended body without falling off, to reliably support a long material, and to Since the body can be stably supported and raised by the guide, long materials can be processed efficiently, and as a result, it has excellent effects that are compatible with mass production methods.
