Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the vertically suspended anodizing treatment of aluminum or aluminum alloy shaped materials, especially long materials such as aluminum sashes, to be anodized objects (hereinafter abbreviated as treated objects).
The present invention relates to a method for facilitating the increase in production of and an apparatus used therefor.

In the above-mentioned anodizing treatment, as shown in FIG. They are subjected to various treatments such as drying in their respective tanks (hereinafter abbreviated as treatment tank group).

These processes are separately disclosed by the applicants (Japanese Patent Application No.
No. 7945), by suspending multiple frames, the capacity of the processing tank can be saved, contributing to improvements in production.

However, in the pre-transportation process up to these tanks and the post-transportation process after treatment, if the frames remain in the long frame state, it is difficult to attach and detach jigs to and from the electrolytic frame, and damage may occur due to mutual contact between the objects to be treated. It has been said that one frame at a time must be transported.

It is clear that if only between processing steps can be mechanically reassembled into long frames, for example, four frames, it will contribute to improving productivity.

The present invention has been made from this point of view, and consists of suspending one end of the objects to be processed, which are placed horizontally in parallel, on an electrolytic frame via a hanging jig, and thereby suspending the electrolytic material in which the objects to be processed are suspended. The frame is lengthened during transportation and subjected to anodizing treatment, and after the treatment process is completed, the long electrolytic frame is dispersed during transportation to form a single frame, and the processed material suspended therein is The present invention relates to a vertically suspended anodic oxidation process that can be easily removed and transferred to the next process, and an apparatus used therein.

Of course, after the anodic oxidation process is completed, the processed material is removed, and the empty electrolytic frame must be returned to the processed material suspension process for further processing. Conversely, since one empty electrolytic frame during transportation can be consolidated into a long frame and returned to the hanging process, the anodizing process can be greatly streamlined.

Hereinafter, this will be explained in detail with reference to the accompanying drawings, which are examples of embodiments.

In Figure 2, ■, ■ are devices for aggregating the number of electrolysis slots, ■,
■ is the dispersion device, and ■ is the transport vehicle, which operates several independently on the rail ■ and transports the electrolytic frames aggregated into 3 to 5 frames as is, and performs degreasing, electrolysis, painting, and baking. Raise and lower the electrolytic frame in each anodizing treatment tank group ① for drying, etc.

In the figure, I and ■ are well-known conversion machines, each containing one electrolytic frame with or without a treated material attached, and I indicates A-B-
V serves to reciprocate between E-F-G.

The processed material attached to the jig is transported to section A by a transfer device (not shown), where it is combined with the empty electrolytic frame returned from section 5 by converter (3).

The combined electrolytic frames are transferred to the aggregation device (2) by the converter I, where they are converted into long frames (represented by 4 frames) during transportation.

) and reach part C. Next, the four electrolytic frames were transferred as they were to the transport vehicle (■), and successively reached the upper part of each treatment tank in the anodizing treatment tank group (■), where they were lowered into the treatment tank with the material to be treated suspended, and placed at the designated location. After being subjected to the treatment, it is lifted up, and after all the treatments are completed in the same way, the four electrolytic frames each with the suspended material are transferred to the 0 part of the dispersion device ■ by the transport trolley ■. The frames are transferred as they are, and the amount of conveyance is dispersed on this device (2), and the frames arrive at section E as one frame.

The electrolytic frames suspended with the processed materials that have reached section E are lowered one by one into section F by the converter ■, where they are separated into the processed materials attached to the hanging jig and empty electrolytic frames. The workpieces attached to the marking jig are transferred to a transport station (not shown) for post-processing.

Empty electrolytic frames must naturally be returned to section A so that they can be recycled, but in order to do this, in this process, these empty electrolytic frames must be consolidated from section F using converter V. Transferred to part 0 of device ■, and transferred again to section 4 on aggregation device ■ during transportation.
The materials are collected into frames and brought to section H, and then the four frames are transferred to one section of the dispersion device (■) using a conveyor truck (■).

The electrolytic frames placed one after another in four frames are dispersed into one frame during transport by the dispersion device (■), resulting in five parts.The fifth part is lowered to part A by the converter (■), where it is attached to a jig. The treated workpiece is then coupled to the empty electrolyte frame and the process sequence is repeated again.

Below, an apparatus for consolidating or distributing electrolytic frames that makes such a series of processes possible will be described.

This device is a pair of endless conveyors arranged in parallel to support and convey electrolytic frames of a predetermined length, and a loading detection mechanism is installed at the loading ends of both conveyors, and a loading detection mechanism is installed near the center of the conveyor surface. A frame blocking mechanism that is located at the bottom and rotates about an axis perpendicular to the direction of movement, is provided with a lever at both ends that has a predetermined interval required for aggregation or dispersion, and has a blocking piece that can protrude onto the conveyor surface. , a frame position confirmation mechanism for checking the presence or absence of the electrolytic frame between the two blocking pieces, and a blocking plate at the transfer end that always prevents the electrolytic frame from moving forward; The electrolytic frame is equipped with a frame position confirmation mechanism that confirms the presence or absence of the electrolytic frame, which is placed on the loading end of the device conveyor intermittently due to the convenience of the front process. The materials are consolidated or decentralized until the end, and are intermittently transferred to the rear process using a conveyor truck or the like depending on the circumstances of the rear process.

First, when the device of the present invention is used as an aggregation device which is an embodiment of the device, for example, when electrolytic frames sent one by one from the previous process are aggregated into four frames, this will be explained in detail with reference to FIG. do.

FIG. 3A is a top view, and the opening is a side view.
The main parts include a blocking plate 7 and frame position confirmation mechanisms 8 and 9.

This conveyor 4 is a set of endless conveyors arranged in parallel at a distance that can support the electrolytic frame depending on the length of the electrolytic frame, and has a mechanism that always rotates in the same direction.
A device in which the rotation and stop are controlled by the method described later, and the electrolytic frames 3, which are placed intermittently one by one on the loading end of the conveyor 4, are collected into four frames by the time they reach the transfer end. It is.

The frame blocking mechanism 6 is connected to the conveyor 4 as shown in the opening of FIG.
A lever 64 is provided below the surface, rotates about a shaft 61 perpendicular to the direction of movement, and has blocking pieces 62 and 63 at both ends spaced apart by a predetermined number of aggregated frames (for example, 4 frames), A linear motion mechanism 65 such as an air cylinder is provided at one end of the lever 64.
This mechanism is such that the blocking pieces 62 and 63 are alternately projected onto and lowered from the surface of the conveyor 4.

The blocking plate 7 is for preventing the electrolytic frame transported by the conveyor from moving forward despite the operation of the conveyor, and temporarily waiting in front of the blocking plate 7.
The loading detection mechanism 5 and the frame position confirmation mechanism 8.9 are constituted by a limit switch or a device having the same effect, and detect whether or not the electrolytic frame is present at a predetermined position on the conveyor.

As shown in FIG. 3, the loading detection mechanism 5 is provided at the loading end of the conveyor 4, the frame position confirmation mechanism 8 is provided between the blocking pieces, and the frame position confirmation mechanism 9 is provided at the transfer end. Mechanism 8
, 9 are attached with limit switches 81-84 and 91-94 equal to the predetermined number of aggregated frames, respectively.

Hereinafter, a method of controlling the conveyor 4 and the frame blocking mechanism 6 using the loading detection mechanism 5 and the frame position confirmation mechanisms 8 and 9 will be described with reference to FIGS.

There are two conditions for starting the conveyor 4. The first condition is when the loading detection mechanism 5 detects the electrolytic frame, and the second condition is when the loading detection mechanism 5 detects the electrolytic frame.
Condition M is when the blocking piece 63 has risen and, conversely, the blocking piece 62 has finished descending.

There are four conditions for stopping the conveyor 4. The first condition N is when the blocking piece 62 is on the conveyor surface and the blocking piece 63 is in the lower position, and the frame position confirmation mechanism 8.9 is in the lower position. This is when a certain period of time has passed since the loading detection mechanism 5 detected the electrolytic frames in a state where all the electrolytic frames were detected,
The second condition O is when the blocking piece 63 is on the conveyor surface and conversely, the blocking piece 62 is in the lower position, and the frame position confirmation mechanism 8
does not detect electrolytic frames in all cases, and the frame position confirmation mechanism 9 detects electrolytic frames in all cases.The third condition P is that the blocking piece 62 is on the conveyor surface and conversely, the blocking piece 63 is on the bottom. The fourth condition Q is when the frame position confirmation mechanism 9 does not detect electrolytic frames at all positions and the frame position confirmation mechanism 8 detects electrolytic frames at all positions. This is when the movement mechanism 65 is in operation.

Here, the conveyor 4 starts rotating when one or more of the starting conditions M are satisfied and all of the stopping conditions N-Q are not satisfied, and one or more of the stopping conditions N-Q are satisfied. Continue rotating until it is filled.

The operating conditions of the linear motion mechanism 65 in the frame blocking mechanism 6 are 2.
The first condition R is when the frame position confirmation mechanism 9 does not detect electrolytic frames in all cases, but the frame position confirmation mechanism 8 detects electrolytic frames in all cases, and the second condition S is when the frame position confirmation mechanism 9 detects electrolytic frames in all cases. This is the case when the confirmation mechanism 8 does not detect electrolytic frames in all cases, but the frame position confirmation mechanism 9 detects electrolytic frames in all cases.

When the first condition R is satisfied, the linear motion mechanism 65 lowers the blocking piece 62 from the upper end position on the surface of the conveyor to the lower end position, and conversely raises the blocking piece 63 from the lower end position to move the conveyor. When the second condition S is satisfied, the blocking piece 63 is lowered from the upper end position on the conveyor surface to the lower end position, and conversely, the blocking piece 62 is moved to the lower end position. It is operated so that it is raised from the position and placed at the upper end position on the surface of the conveyor.

Next, the centralizing operation mode of this device will be explained with reference to FIG.

Now, when the electrolytic frames 3 are placed one by one on the loading end (position B in Figure 2), the loading detection mechanism 5 detects the loading.
As described above, the conveyor 4 starts rotating, and the electrolytic frames 3 placed on the stacking end sequentially move to the blocking piece 62.

FIG. 4a shows a state in which three frames have already been blocked by the blocking pieces 62 and the fourth frame has been placed on the loading end.

When the fourth frame advances and accumulates after the third frame, the frame position confirmation mechanism 8 detects 4 frames, which is the predetermined number of frames to be aggregated, so the conveyor 4 stops due to the above-mentioned P, and at the same time moves linearly due to R. The mechanism 65 operates to lower the blocking piece 62, and conversely, the blocking piece 63 rises as shown in Figure b, separating these four frames from the subsequently conveyed frame.

Then, at the same time, the conveyor 4 starts rotating again due to the above-mentioned M, so the separated four electrolytic frames are conveyed as a group on the conveyor and the blocking plate 7
Reach the front.

This state is shown in Figure 0.

When the frame position confirmation mechanism 9 detects all the electrolytic frames, the conveyor 4 is stopped by the above-mentioned O, and at the same time, the linear motion mechanism 65 is activated by S, and the lever 64 rotates around the fulcrum 61. The positions of the blocking pieces 62 and 63 are reversed, resulting in the state shown in Figure d.

The electrolytic frames that have been aggregated into four frames and have reached the front surface of the blocking plate 7 are sent to the rear process by a conveyance truck or the like, so that the frame position confirmation mechanism J no longer detects any electrolytic frames.

At that time, if the frame position confirmation mechanism 8 detects all the electrolytic frames, if the conveyor 4 is rotating due to P and R described above, it will stop, and at the same time the linear movement mechanism 65 will operate, and as shown in Figure b. You will have to go back and repeat the process described above.
If the multiple frame position confirmation mechanism 8 does not detect four frames, which is the predetermined number of frames to be aggregated, the steps from Figure a are repeated.

As mentioned above, the electrolytic frames that are sent one frame at a time intermittently due to the circumstances of the front process are temporarily accumulated in front of the blocking pieces 62 and 63, and are sequentially sent four times due to the circumstances of the rear process (for example, processing time, etc.). Since it is consolidated into frames and sent to the downstream process, there is no wasted time and it is possible to consolidate from 1 frame to 4 frames.

Although the case where the device of the present invention is used as an aggregation device is described above as an embodiment of the device, it goes without saying that various modifications can be made without departing from the scope of the present invention.

It is clear that the device of the present invention can be used as a dispersion device.

For example, FIG. 5 shows a case where, at the second drawing position, four electrolytic frames are placed on the stacking end, and the electrolytic frames are separated into one frame during transport and sent to the rear process.

In this case, the levers 64 of the frame blocking mechanism 6 are set at a predetermined interval necessary for dispersion, the frame position confirmation mechanisms 8 and 9 are J-mit switches equal to the predetermined number of frames to be distributed, and the conveyor 4,
By controlling the linear motion mechanism 65 of the frame blocking mechanism 6 in the same manner as described above, the electrolytic frames are dispersed from four frames to one frame.

Next, the consolidation or decentralization of electrolytic frames can also be carried out using the following apparatus.

That is, a pair of endless conveyors are arranged in parallel to support and convey an electrolytic frame of a predetermined length at both ends thereof, and a loading detection mechanism is located at the loading end of both conveyors, and a loading detection mechanism is located below the surface of the conveyor. and a frame stopper having a rotary stopper having a recess into which the end of the electrolytic frame is fitted rotates around an axis perpendicular to the direction of movement, and a brake mechanism for stopping the rotation of the rotary stopper. Next to the rotary stopper is a mechanism for checking the number of passing frames, and at the transfer end there is a blocking plate that always prevents the advancement of the electrolytic frame. A frame position confirmation mechanism is provided to confirm the position.

However, in the device of the present invention, the frame position confirmation mechanism is installed before the frame blocking mechanism.

The frame passing number confirmation mechanism 10 is constituted by a limit switch or a device having the same effect as this and a counter, and detects the number of electrolytic frames that have passed through the frame blocking mechanism.

During the day, the frame blocking mechanism is operated by the conveyor 4 as shown in the opening in Figure 6.
A rotary stopper 66, which is located below the surface and has a recessed notch 67 into which the end of the electrolytic frame fits, is rotatable about an axis 61 perpendicular to the direction of movement. A known brake mechanism (not shown) is provided in order to stop the electrolytic frame moving by the operation of the conveyor 4, and the rotation of the rotary stopper 66 is stopped by the operation of the brake mechanism. prevent the advance of

The blocked electrolytic frames are swept over the conveyor 4 in front of the rotary stopper 66, and the electrolytic frames that are sequentially conveyed are accumulated.

In addition, when the brake mechanism is released, the conveyor 4
The electrolytic frames moving by the operation are fitted one by one into the recessed part 67 of the rotary stopper 66 and moved toward the blocking plate 7.

A method of controlling the conveyor conveyor 4 and the frame blocking mechanism 6 using the loading detection mechanism 5 and the frame position confirmation mechanisms 8 and 9 will be described below.

There are two conditions for starting the conveyor 4, the first condition T
is the case where the loading detection mechanism 5 detects the electrolytic frame, and the second
Condition U is when the frame position confirmation mechanism 9 no longer detects any electrolytic frames.

Condition V for stopping the transport conveyor 4 is when a certain period of time has elapsed since the loading detection mechanism 5 detected the electrolytic frames, and the frame position confirmation mechanisms 8 and 9 detected all the electrolytic frames.

Here, the conveyor 4 starts rotating when at least one of the starting conditions T and U is met, and the stopping condition V
Continue rotating until it is filled.

Condition W in which the brake mechanism (not shown) operates in the frame blocking mechanism 6 to stop rotation of the rotary stopper 66
is when the frame passage number confirmation mechanism 10 has confirmed the predetermined number of aggregation or decentralization frames that have been set in advance, and the condition This is the case when the position confirmation mechanism 8 does not detect electrolytic frames in all cases, but the frame position confirmation mechanism 8 detects electrolytic frames in all cases.

Since the device of the present invention is configured and controlled as described above, the frame position confirmation mechanisms 8 and 9 and the frame passing number confirmation mechanism 1 of the device are as follows.
By setting 0 according to the number of frames required for consolidation or decentralization, the electrolytic frames placed on the loading end are consolidated or decentralized by the time they reach the transfer end.
