By this method, the number of the suspended materials can remarkably be increased, and this method can contribute greatly toward improving treatment efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION J Field of the Invention The present invention relates to an improvement in a surface treatment method, such as alumite treatment, in which a large number of aluminum profiles are suspended from a conveyor frame.

``Prior art'' Normally, when a long aluminum profile is anodized, the extruded profile is cut into predetermined dimensions, loaded on a pallet for transportation, heated as is in a heat treatment furnace, and then As shown in FIG. 7, the aluminum shapes M are transferred to the processing line along with the pallet 4, and each shape M is hung vertically on a conveying frame 1 that moves over the following treatment tanks 3 via rails 2. It can be hung in a degreasing tank, washing tank, etching tank, washing tank, neutralization tank, alumite tank (or electrolytic tank).
・After carrying out the predetermined alumite treatment on the aluminum profile M by sequentially transporting it to a water washing tank, a color treatment tank, etc., the profile M is removed from the transport frame 1 and loaded onto another pallet 4 again. It will be transferred to the final shaping process.

Therefore, in a surface treatment method having such a series of treatment cycles, it is theoretically possible to improve the treatment efficiency by suspending as many aluminum profiles M as possible on the transport frame 1.

However, when suspending the aluminum profile M on the transport frame 1, a holding means (not shown) is usually provided on the transport frame 1 side.
Generally, a method is adopted in which the shapes M are fixed at regular intervals and the shapes M are individually hung from each holding means.In this case, when the worker is loaded on the pallet Carry out the molded materials M one by one, and place one into each of the above-mentioned holding means.
Since one book must be attached, if a large number of aluminum shapes M are to be suspended from the transport frame 1, the work will require a considerable amount of time.

Moreover, in a general treatment factory, the optimal cycle time from the first installation to the final removal is determined based on the process that takes the longest time in each treatment tank 3 (usually the processing time in the alumite tank). Since it is set in advance,
It was virtually impossible on the site to spend a long time just installing and removing the shape material M.

Therefore, in the processing factory, the time for installing and removing the aluminum shapes M is calculated based on the processing cycle time of each person, regardless of the number of aluminum shapes M. The number of hanging pieces to the transport frame 1 is naturally limited, and the reality is that only the number of pieces M that is less than the processing capacity can be hung from the carrying frame 1. Therefore, from the viewpoint of processing efficiency, the number of hanging pieces is limited. Improvement is strongly desired.

The easiest way to improve this point is to increase the number of workers engaged in attaching and removing aluminum shapes M, so that it is possible to suspend as many shapes M within a predetermined time. Although this method is possible, it is not a sufficient solution because it would increase labor costs unnecessarily and go against the current demands for rationalization.

Therefore, in recent processing factories, processing efficiency has been improved by increasing the number of hanging shapes M by adding a structure to the holding means itself that makes it easy to attach and detach the aluminum shapes M, and by performing automatic racking. Various methods have been tried to do this.

[Problem that the invention attempts to solve] However, these conventional measures are just that.

Based on the conventional method of suspending one section M on one holding means, we have only made improvements in this relationship, so if we look at it as a whole, the installation and installation of the section M will be much easier. We cannot expect a sufficient reduction in removal time,
A large increase in the number of hanging aluminum shapes M cannot be expected.

Moreover, the former method of providing a structure that facilitates attachment and detachment to the holding means itself requires the use of a dedicated holding means depending on the shape of the mold M, so that the holding means must be held every time the shape of the mold M changes. The means had to be replaced, and this complicated replacement work became a problem in terms of processing efficiency.Also, the latter automatic racking method also had to overcome the limitations of the shape of the mold material M. After receiving all the mold materials M
Since it cannot be subjected to automatic racking, it is also seen as a problem in terms of versatility, and in any case, it has not been possible to sufficiently respond to the diversification of shape materials in the present day.

For this reason, in this field, the maximum possible number of aluminum profiles M can be installed and removed within the time required for attaching and removing the profiles M determined by a series of processing cycle times, without being affected by the shape of the aluminum profile M. There is great excitement for the emergence of a new system that can do this.

``Means for Solving the Problems'' Therefore, the present invention was developed in response to such a request, and is a method for vertically suspending a large number of surface-treated materials on a conveying frame via a holding means. The technical premise is that the surface treatment method has a series of treatment cycles in which the surface treatment material is lowered and transported to each treatment tank in order, and after performing a predetermined surface treatment on the material to be surface treated, the material to be surface treated is removed from the transport frame. By fixing a common set plate to one end of an arbitrary number of surface-treated materials among the large number of surface-treated materials, and having the set plate itself held by the holding means, a large number of surface-treated materials can be We adopted a configuration in which the robot is suspended from a transport frame.

"Operation" Therefore, in the present invention, if one end of each material is fixed to a common set plate before the material to be surface treated is transported to the processing line, the material can be transported to the processing line. At the time when a considerable number of materials are already fixed to a common set plate, one worker can only use this one set plate.
If individual set plates are carried out from the pallet and held in the holding means provided on the transport frame side, a considerable number of materials can be handled at once in one operation, albeit indirectly. It is possible to hang it on the transport frame.

Therefore, under the surface treatment method of the present invention, as before,
Since there is no need to transport the materials one by one from the pallet and hang them individually on the holding means on the transport frame side, the installation time is greatly reduced, and the installation determined by the cycle time can be done quickly. In addition to making it possible to attach the maximum number of surface-treated materials to the transport frame within the time limit, even when removing the surface-treated materials from the transport frame, for the same reason, it is possible to attach the maximum number of surface-treated materials to the transport frame within the removal time determined by the cycle time. This makes it possible to efficiently remove the maximum number of materials from the transport frame.

"Example" The present invention will be described in detail based on an example illustrating the present invention.
The surface treatment method according to this embodiment also targets a long aluminum profile M, in which the long aluminum profile M is vertically suspended from the transport frame 1 via a holding means, and transferred to each treatment tank 3. This method is based on a surface treatment method having a series of processing cycles in which the mold material M is conveyed in order, and after surface treatment is performed on the mold material M, the mold material M is removed from the transport frame 1. Aluminum profile M medium
By fixing a common set plate 10 to one end of an arbitrary number of shapes M and having the set plate 10 held by the holding means, a large number of shapes M can be indirectly suspended from the transport frame 1. be.

To explain this specifically, in this embodiment, the set plate 10 is formed into a plate-shaped body of a desired size, and as shown in FIG. Either one end of the winter shape material M is mechanically welded at regular intervals and one end of the winter shape material M is directly fixed to the set plate 10 at a constant distance, or as shown in FIG. As shown, other auxiliary holders 11 are provided on the set plate 10 at intervals in advance, and by holding one end of the mold material M with each auxiliary holder 11, one end of each mold material M is fixed. shall be fixed to the set plate 1o.

Incidentally, the auxiliary holder 11 provided on the set plate 1o is not limited to the one having the cam-type clamping claws 12 shown in the figure, but may be any auxiliary holder 11 provided that the mold material M can be easily attached and detached. - As shown in B-C, there are some auxiliary holders 11 that utilize the elastic force of the rubber body 13, those that utilize the tightening force of the screw body 14, and those that utilize the fastening force of the pin body 15. It is also fully possible to use

Then, one end of a considerable number of the shape materials M is set on a set plate 10.
It is possible to fix the mold material M at any time before hanging it on the transport frame 1.
If they are fixed before being loaded on the set plate 10, it becomes possible to load a considerable number of the shapes M together with the set plate 10 at once, so from the viewpoint of workability, this point is most preferable.

Therefore, when an aluminum profile M is subjected to alumite treatment using such a set plate 1o, when the profile M is loaded on the pallet 4 and transported to the processing line, as described above.

Since a considerable number of the shapes M have already been fixed to the common set plate 1o via welding or auxiliary holding All, the worker carries out one set plate 10 as a unit from the pallet 4, and carries it out from the pallet 4 as shown in FIG. As shown in B, if the set plate 10 itself is held by each holding means 16 provided on the transport frame 1 side, a considerable number of shapes M can be attached to the transport frame l at once in one operation. becomes possible.

Therefore, under the surface treatment method of this embodiment, whether it is loaded on the transport pallet 4 or transported, the workers can handle only one piece at a time, as in the past.
Since a considerable number of mold materials M can be handled at the same time, time can be greatly reduced in this respect as well.

Furthermore, when attaching the shapes M to the transport frame 1, there is no need to hang the shapes M one by one from the holding means 16 of the transport frame 1 as in the past, so the installation time can be significantly reduced. By shortening the installation process determined by the cycle time, it is possible to efficiently attach a large number of molds M to the transport frame 1 within the time, and even when removing the molds M from the transport frame 1, the same process can be performed. For this reason, within the removal time determined by the cycle time, a large number of profiles M
Since it becomes possible to efficiently remove the material from the transport frame 1, it is of course possible to expect an improvement in processing efficiency, but compared to the conventional method, it is also possible to reduce the number of workers, so it is suitable for the current demands for rationalization. It will also be possible to respond.

Further, conventionally, the holding means 16 provided on the transport frame 1 side
The number of suspended shapes M is determined by the number of shapes M, so even if the device has a processing capacity of, for example, 200 shapes, only 100 holding means 16 must be provided in the transport frame L. For example, 100 pieces M
However, in this embodiment, by adopting a new set plate 10, the transport frame 1 can be suspended.
To.

Without being restricted by the number of holding means 16 provided, it is possible to easily suspend the maximum number of shapes M within a possible range.

Note that the holding means 16 provided on the conveyance frame 1 side.

Since various existing holding tools, clamping tools, etc. currently in use can be used, it can be implemented immediately without making any changes to factory equipment. However, the holding means 16 itself may have any structure as long as it can hold the set plate 10 reliably.
For example, as shown in FIG. 5, a 5-shaped hook means 16A is provided on the conveyance frame 1 side, a locking ring 17 is provided on the set plate 10 side, and the locking ring 17 is locked to each hook means 16A. By doing so, the aluminum profile M is configured to be suspended on the transport frame 1, or as shown in FIG. A locking shaft 18 is provided, and the corresponding locking shaft 18 is fitted into each holding cylinder means 16B, and the holding cylinder means 16B is inserted into the notch 18a of the locking shaft 18.
It is also optional, depending on the implementation, to configure the aluminum profile M to be suspended from the transport frame 1 by locking a lock claw (not shown) inside.

Furthermore, in this embodiment, regardless of the shape of the aluminum profile M, if the shape of the set plate 10 itself is standardized, not only loading and unloading onto and from the pallet 4 but also the holding means 16 of the transport frame 1 can be performed. Since it becomes possible to completely automate the installation and removal of the equipment, it is possible to perform such automation and to greatly improve productivity in an unmanned state.

Moreover, in this case, the shape material M is fixed to the set plate 10 and is not directly held by the holding means 16, so the method of this embodiment also allows for diversification of the shapes of the shape material M. This makes it possible to respond adequately.

"Effects of the Invention" As described above, in view of the drawbacks of the conventional method in which the materials to be surface treated are suspended one by one from the holding means provided on the conveyance frame, the present invention provides a method for suspending one end of the materials to be surface treated by By adopting a new configuration in which a large number of surface-treated materials are suspended from a transport frame by fixing a common set plate to the set plate and holding the set plate itself by the holding means, the material can be loaded onto a transport pallet. Of course, it is possible to handle a considerable number of materials at a time when transporting the materials, but when attaching the materials to the transport frame, it is necessary to suspend the materials one by one from the holding means of the transport frame, as in the past. Since there is no need to worry, installation time is greatly reduced.
The installation determined by the cycle time is within the time,
The maximum number of materials can be attached to the transport frame, and for the same reason, even when removing materials from the transport frame, the maximum number of materials can be removed from the transport frame within the removal time determined by the cycle time. It has become possible to remove it.

Moreover, in the present invention, by adopting a new set plate, it is possible to suspend as many materials as possible without being restricted by the number of holding means provided on the transport frame. Therefore, in any case, it is possible to significantly increase the number of hanging materials and greatly contribute to improving processing efficiency.

In addition, no matter what shape the material to be surface treated is, the material is only fixed to the set plate and is not directly held by the holding means provided on the conveyance side, so the set plate cannot be standardized. By doing so, it becomes possible to automate all processes, and there is no need to worry about restrictions on automation due to the shape of the material itself.

Furthermore, since the surface treatment method of the present invention can be immediately applied without making any changes to existing factory equipment, its practicality is extremely great.
