It will have a very useful effect such as maximization.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The overall configuration of the transfer rail device 10 for the base material for the phosphate film treatment according to the present invention, as shown in Figure 1 and 2, respectively, a plurality of treatment tanks stored the processing solution for the phosphate film treatment of the base material ( 1) is arranged in accordance with the order of the film treatment, the upper portion of the treatment tank (1) has a transfer rail (2) for automatically dipping and detaching the base material into each treatment tank (1) It is installed, the transfer rail 2 is installed along the rail support (5) which is located at regular intervals on the outer side of the treatment tank (1).

The treatment tank 1 has a primary washing treatment tank 11, a pickling surface treatment tank 12, a phosphate treatment tank 13, a secondary washing treatment tank 14, and alkali washing in the drawing. The neutralization treatment tank 15 and the soap cleaning lubrication treatment tank 16 are sequentially arranged along the traveling direction of the base material (left to right on the drawing), while the treatment time required by the treatment tank 1 For example, the treatment tank 1 and the upper side transfer rail 2 are installed to have an appropriate transfer distance in accordance with the phosphate treatment 6 minutes, the lubrication 3 minutes 25 seconds, and the immediate treatment within 1 minute. It is.

The conveying rail device 10 forming the main part of the present invention, the roller coaster continuous in a zigzag form along the up and down directions, so that the base material can be automatically immersed and separated from each treatment tank (1). ) The feed rail 2 of the shape as a main component, the upper inflection point of the transfer rail 2 is located between each treatment tank 1, the lower inflection point of the transfer rail 2 is each treatment It is located inside the tank 1.

When the transfer rail 2 of the base material is installed in the above manner, even if the hoist or hydraulic cylinder for lifting and lowering as in the conventional case is not installed, the respective base materials are transferred in the process of transferring the base material along the transfer rail 2. It can be immersed and detached into the interior of the treatment tank 1, thereby phosphate coating treatment for the base material can be carried out sequentially and automatically just by transferring the base material along the transfer rail (2).

Therefore, even if an operator does not reside around each treatment tank 1, the phosphate coating treatment of the base material can be performed, thereby preventing unnecessary waste of manpower, as well as conveying the lifting device and the control device. It is also possible to prevent unnecessary waste of time and time by installing it separately, and greatly improve productivity and economic efficiency due to the phosphate coating of the base metal, while preventing workers' industrial accidents caused by harmful gases. It will also contribute greatly to this.

Detailed configuration of the conveying rail apparatus 10 according to the present invention is used as the conveying rail 2, the section steel having a roughly "engineer" cross section, as shown in Figures 1 to 5 more clearly, Along the rail 2, a hanger feeder 6 having a rail roller 61 is provided at regular intervals, and each of the hanger feeders 6 is a feed chain located at the lower portion of the feed rail 2. (7) is connected and installed, the base material mounting hanger (3) is connected to the lower end of each hanger feeder (6).

The conveying rail 2 and the conveying chain 7 extend from the upper portion of each treatment tank 1 in a roller coaster manner, starting from a loading mechanism of the base material (not shown), and then unloading the base material. While forming a circulating loop type conveying path which returns to the loading mechanism side of the base material through the unloader, the conveying rail 2 is provided with a circulating loop rotating operation of the conveying chain 7. Large sprockets, not shown, are installed.

Therefore, by the circulation loop type rotation operation of the conveying chain 7 according to the driving of the sprocket, the base material hanger 3 can move along the conveying rail 2 together with the hanger conveying table 6. In the process of moving the hanger 3, the mounting work of the base material by the loading mechanism and the phosphate coating treatment of the treatment tank 1 and the removal of the phosphate film-treated base material by the unloading mechanism are performed.

In particular, in the present invention, as shown in Figures 1 to 5, so that the transfer rail device 10 can be optimally applied to the manufacturing field of the seamless metal container, the transfer rail (2) is the base material The transfer rails 21, the cup base material transfer rails 22, and the tube base material transfer rails 23 are divided into three rails 21, 22 and 23, and each transfer rails 21 and 22 are divided. ) 23 is arranged to be horizontally arranged at regular intervals from the upper portion of the treatment tank (1).

In addition, the hangers 3 moving along the respective transfer rails 21, 22, 23 are likewise, the base plate hanger 31 for mounting the disc base material 8, and the disc base material ( A cup base material hanger 32 for mounting the cup base material 9 formed by the primary deep drawing process of 8) and a tubular base material 9 'molded by the final deep drawing process of the cup base material 9. ) To be a tube base hanger 33 for mounting.

In the case of the disk base material conveying rail 21, the cup base material conveying rail 22 and the tube base material conveying rail 23, as described above, the loading mechanism of the corresponding base material 8, 9, 9 'is started. Each of them independently extends in a zigzag fashion along each treatment tank 1 and then returns to the loading mechanism side of the base material through the unloading mechanism of the base material 8, 9, 9 '. Phosphorus loop loop transfer path is formed.

In addition, in the case of the original base material hanger 31, the cup base material hanger 32, and the tube base material hanger 33, the original base material 8, the cup-shaped base material 9 or the tubular base material 9 ', respectively. As long as the hanger 3 of any shape can be used as long as it can be mounted and detached, the base material 8, 9, 9 'can be attached to and detached from each hanger 31, 32, 33. Hanger 31, 32, 33 in consideration of the convenience of work and the safety of the transport of the base material (8) (9) (9 ') and the light weight of the hangers (31) (32) (33) at the same time. It is necessary to optimize the structure of.

To this end, the base plate hanger 31 is connected to the hanger plate 6 is connected to the hanger transfer table (6) by link link 35a, as shown more clearly in Figure 3, and A pair of main support base 34 connected to be installed in a "∧" shape at the lower side of the connecting plate 35, and a storage bending portion formed to be bent in a "U" shape at the lower end of the main support 34 ( 34a) and an inlet end portion 34b extending inclined outwardly from the storage bending portion 34a.

When the base material hanger 31 is formed in the shape as described above, the weight of the hanger 31 itself can be reduced to the maximum weight, and the hanger 31 is almost free from the diameter of the base material 8. The original base material 8 can be easily mounted in the vertical direction on the main support base 34 and the lower storage side bending portion 34a of the main support base 34, and the work of separating the original base material 8 from the hanger 31 can also be performed by using a magnet or the like. It can be easily performed using a vacuum suction plate or the like.

In addition, even when a situation in which the center of the master substrate 8 and the hanger 31 are slightly displaced during the mounting process of the master substrate 8 occurs, the master substrate inserted through the lower storage bending portion 34a of the hanger 31 is inserted. (8) can be rolled in both directions (moving direction of the hanger on the drawing) to be able to grasp the center by itself, thereby enabling the base substrate 8 to be more stably mounted on the hanger 31.

In the drawing, the horizontally fixed between the main support stands 34 is a reinforcement stand 34c of the base plate hanger 31, and the hanger 31 is linked on the hanger carriage 6 by the link stand 35a. The reason why it is installed in such a manner is that, in the loading operation in which the master substrate 8 is upright in the vertical direction to mount the master substrate 8 on the hanger 31, the hanger 31 is pushed out in close contact with the loading mechanism. Even if the hanger 31 itself is to maintain the vertical direction at all times.

In addition, the main base stand 34 is provided on the front surface of the connecting plate 35 so that the disc base material 8 mounted on the hanger 31 can be more completely prevented from being separated from the hanger 31. And a swing bar 35b spaced apart from each other at a predetermined interval, that is, a gap into which the disc base material 8 can be inserted, is installed to be angular motion suspended in a clock-like shape, and a lower end of the swing bar 35b is also drawn in. Similarly to the end portion 34b, the base member 8 is formed to be inclined downward to the outside for easy mounting.

The swing bar 35b is folded in one direction at the time of mounting the master base material 8 by the loading mechanism, and then restored to the position shown in the drawing when the mounting of the master base material 8 is completed. , Base plate 8 mounted on the hanger 31 can be supported more securely without being separated between the main support 34 and the swing bar (35b).

And, the cup base material hanger 32 is as shown more clearly in Figure 4, so as to face at regular intervals while forming a "L" shaped frame for seating and support of the cup-shaped base material 9 A pair of base material storage frames 36, an upper side connection frame 36a for connecting the respective base material storage frames 36, and a connection for connecting the connection frame 36a to the hanger carriage 6 in a link manner. Plate 39 and the rear support (36b) is provided on the rear side of the base material storage frame 36 to prevent the cup-shaped base material (9) to fall off.

The gap formed between the lower end of the base material storage frame 36 is inserted into the lower side of the conveyor-type feed roller for loading and unloading the cup-shaped base material 9 to be in close contact with the bottom surface of the cup-shaped base material 9. While being able to, the cup-shaped base material 9 itself is spaced apart so as not to fall through the bottom of the hanger 32, the frame structure of the shape different from that shown in Figure 4 can be applied as the cup base material hanger 32 Of course, if necessary, instead of the frame structure may be formed of a container (storage container) structure.

However, as in the optimum embodiment of the present invention shown in FIG. 4, it is possible to form the hanger 32 as a frame structure by a pipe (which may be a hollow pipe), so that the weight of the hanger 32 itself is maximized. It is most preferable in terms of being lightweight and providing sufficient strength to support the cup base material 9, as well as reasonable structural design associated with the loading and unloading mechanism of the cup base material 9, not shown. .

In addition, the lower end side central portion of the hanger 32 is installed so as to be connected between the base holder (37) of the arcuate storage frame 36, and extends downward by a predetermined length in the lower center portion of the holder (37). As the lower protrusion rod 38 is installed, the holder 37 supports the cup-shaped base material 9 more securely in the interior of the hanger 32, as well as by the lower protrusion rod 38 thereafter. It is even more preferable to carry out the operation of discharging the treatment solution by the eccentric rail 4 described in the following.

And, the tube base material hanger 33 is more clearly shown in Figure 5, the overall appearance is made the same as the cup base material hanger 32, the only difference is the cup-shaped base material (9) In the case of), the length is short and the diameter is long, whereas the tubular base material 9 'is longer in length and smaller in diameter than the cup base material 9, so only the dimensional side of the hanger 33 is adjusted accordingly. It is.

As described above, the transfer rail 2 is divided into three rails 21, 22, 23, and the original base material 8 and the cup-shaped base material 9 are formed along the respective rails 21, 22, 23. And the tubular base material 9 'are simultaneously transported, a series of phosphate coating treatments of all the base materials (original, cup-shaped, tubular, base material) for producing a seamless metal container in connection with the deep drawing ironing method. By using the treatment tank (1) of the can be performed in a more rational process, the transfer rail device for the base material for the phosphate coating treatment that can be more optimally applied to the manufacturing field of the seamless metal container (10) Can be provided.

As described above, in the process of performing the phosphate coating treatment of the original base material 8, the cup base material 9 and the tubular base material 9 ', in the case of the cup base material 9 and the tubular base material 9', the corresponding base material (9). In the process of immersing and releasing (9 ') into each of the treatment tanks 1, the treatment solution stored in the treatment tank (1) due to the structural characteristics of the base materials (9, 9') is the base material (9) (9). The situation remaining inside ') may occur.

In other words, the cup-shaped base material 9 and the tubular base material 9 'have a container shape in which the front end inlet side thereof is opened and the rear end part has a closed state, so that the base material 9 (inside the respective treatment tanks 1) ( 9 ') is immersed in the treatment solution and then exits from the treatment tank 1, the treatment solution is not completely discharged to the outside of the base material (9) (9') and the inside of the base material (9) (9 ') May be left behind.

When the above situation occurs, the surface of the level required by the treatment tank 1, as the treatment solution remaining in the base material (9) (9 ') is mixed with other treatment solution in the next treatment process. Of course, it may adversely affect the treatment, and the replacement cycle of the treatment solution stored in each treatment tank 1 is shortened, resulting in an uneconomic problem.

In order to prevent this, the treatment solution introduced into the base 9, 9 'is completely discharged in the process of separating the cup base 9 and the tubular base 9' from the respective treatment tanks 1. To be able to do this, each of the base materials 9 and 9 'must be set to be inclined together with the hangers 32 and 33 with the open inlet side of the cup base material 9 and the tubular base material 9' facing downward. .

In order to achieve the above function, each hanger 32, 33 itself is mounted on the hanger 32, 33 by hanging inclined in an eccentric state on the hanger carriage 6 Although the inlet of the cup-shaped base material 9 and the tubular base material 9 'may be directed downward, in this case, when a shock or vibration occurs in the transfer process of the hangers 32 and 33, the cup-shaped base material 9 is formed. The tube-like base material 9 'can be caused to emerge from the hangers 32 and 33.

Therefore, most preferably, in the process of conveying the cup-like base material 9 and the tubular base material 9 'by the hangers 32 and 33, the corresponding base material 9 and 9' are positioned in position, that is, each hanger 32. The cup base material 9 and the tubular base material 9 'are hangers only while the base material 9 and 9' are pulled out from each treatment tank 1 while being mounted in a horizontal position on Together with (32) and (33), the discharge of the treatment solution is inclined in a possible direction.

To this end, the eccentric rail 4 as shown more clearly in Figures 6 to 8 is applied, in order to help the installation state of the eccentric rail 4 and the convenience of understanding thereof in Figures 6 and 7 Only the portion of the phosphate treatment tank 13 is enlarged and representative, and in FIG. 8, only the portion of the cup base material transfer rail 22 is enlarged and representative in order to facilitate the understanding of the working relationship of the eccentric rail 4.

Therefore, in the following description, the installation and working relationship of the eccentric rail 4 will be described based on the phosphate treatment tank 13 and the cup bristle conveying rail 22 based on the drawings, but as shown in FIG. The rails 4 are installed under each of the cup base material conveying rails 22 and the tube base material conveying rails 23 in all the processing tanks 1, respectively.

While being installed side by side in the horizontal direction along the eccentric position from (23) (Fig. 7), the transfer rail 22 at regular intervals in the lower portion of the cup base material transfer rail 22 and the tube base material transfer rail 23 ( It is installed along the same path as 23) (Fig. 6).

In addition, the lower end of the cup base material hanger 32 and the tube base material hanger 33 is provided with a bar-shaped guide means that is inserted and guided along each eccentric rail 4, the hanger according to the present invention In the optimal embodiment of (32) (33), the guide means is a lower protrusion rod (38) installed in the lower end of the holder (37) in Figs.

In addition, the tip inlet (left end of the rail in FIGS. 6 and 7) of each eccentric rail 4 has a lower protruding rod 38 as a guide means, safely and easily, regardless of the swing of the hangers 32 and 33. Each eccentric rail 4 is formed of a leading end portion 42 having a " > " shape that can be inserted into a wide gap (preferably about 4 to 10 times the diameter of the lower protrusion rod 38). Silver is installed to be supported by the rail support 41 fixed to the bottom of each treatment tank (1) including a phosphate treatment tank (13).

With the eccentric rail 4 installed as above, as shown in FIG. 8A, together with the hanger 32 along the inlet of the initial cup base material transfer rail 22 and the eccentric rail 4. In the process of immersing the cup-shaped base material 9 which is conveyed to the correct position into the processing solution stored in the processing tank 1, as shown in (b) of FIG. 8, from the cup base material conveying rail 22. The cup-shaped base material 9 is inclined along the direction of the arrow with the hanger 32 so that the inlet side opened by the lower protrusion rod 38 inserted along the eccentric rail 4 having the eccentric position faces downward.

As described above, the surface treatment of the cup-shaped base material 9 is performed in the treatment tank 1 in the state where the position of the cup-shaped base material 9 is adjusted by the eccentric rail 4, and then, in FIG. While leaving the state shown in the treatment tank (1) to be pulled out, whereby the treatment solution of the treatment tank 1 flows down to the treatment tank (1) side through the inlet of the cup-shaped base material (9), The processing solution is not left inside the cup base material 9.

The above working relationship is made equally along the cup base material transfer rail 22 and the tube base material transfer rail 23 in each treatment tank 1 equipped for the phosphate coating treatment, and thus the cup-shaped base material 9 The treatment solution does not remain inside the tubular base material 9 ', so that the surface treatment required by each treatment tank 1 can be performed and the replacement cycle of the treatment solution can be extended to the maximum. As such, the efficiency and economics of phosphate coating can be maximized.

In the drawing, the eccentric rail 4 is shown as two rows of bar-shaped rails spaced apart at regular intervals, that is, at intervals at which the lower protrusion rod 38 can be inserted and guided. It is a matter of course that the "凹" -shaped rail in which the guide groove is formed so that the lower protrusion rod 38 can be inserted and guided to the upper end of the rail can be applied, and of the hangers 32 and 33 by the eccentric rail 4. The inclination angle is preferably 5 degrees to 10 degrees for smooth discharge of the treatment solution and prevention of separation of the base material 9 and 9 '.

Further, the rear end (right end) exit of each eccentric rail 4 is in the same line as the transport rails 22 and 23 from the position eccentric with the corresponding transport rails 22 and 23, as shown in FIG. By placing it so that the process of detaching the hangers 32 and 33 from the eccentric rail 4 is in the state shown in Fig. 8B from Fig. 8B. It is preferable to prevent the hangers 32 and 33 moving along) from swinging.

In addition, it is shown in the drawing that the eccentric rail 4 extends from the inlet (left end) of the treatment tank 1 to the outlet (right end) of the treatment tank 1 via the bottom of the treatment tank 1. However, the eccentric rail 4 may be installed only from the center of the bottom of the treatment tank 1 to the outlet of the treatment tank 1, in which case it is immersed together with the base material 9, 9 ′ into the treatment solution. Preferably, the width of the leading end portion 42 is made larger so that the lower protruding rods 38 of the hangers 32 and 33 can be reliably inserted along the eccentric rail 4.

As the most preferred embodiment of the eccentric rail 4, as shown in Fig. 9, the cup-like base material 9 and the tubular base material 9 'is introduced into the treatment tank 1 (phosphate treatment tank on the drawing) and On the basis of the time point discharged from the treatment tank 1, each of the eccentric rails 4 is a corresponding transfer rail so that the opened inlet of the base material 9, 9 'can be inclined upward and downward. (22) (23) It is provided in the zigzag eccentric manner in the lower both sides (upper and lower side in drawing).

When the eccentric rail 4 is installed in the above manner, as shown in Fig. 10A, the cup base material 9 (including the tubular base material, the same below) enters from the inlet of the treatment tank 1. At this point in time, the cup base material 9 is inclined along the arrow direction with the hanger 32 so that the open inlet side of the cup base material 9 faces the upper side direction, whereby the treatment solution stored inside the treatment tank 1 This can be introduced more quickly and smoothly into the cup-shaped base material (9).

In the above state, as shown in (b) of FIG. 10, in the process of passing through the central inflection portion of the eccentric rail 4, that is, a portion crossing the conveying rails 22 and 23 diagonally in FIG. 9. After returning to the horizontal direction, as shown in (c) of FIG. 10, at the time of exiting toward the outlet side of the treatment tank 1, the cup inlet side of the cup-shaped base material 9 faces the lower side direction. As the base material 9 is inclined along the direction of the arrow with the hanger 32, the treatment solution stored inside the cup-shaped base material 9 is completely discharged from the base material 9.

When the eccentric rail 4 is installed in the same manner as described above, when the cup-shaped base material 9 or the tubular base material 9 'is immersed in the treatment tank 1, the base material 9, 9' is removed. The treatment solution can be smoothly introduced into the interior, and the treatment solution is completely discharged from each of the base materials 9 and 9 'at the time when the substrate 9 and 9', which have been surface-treated, exits from the treatment tank 1. It can be discharged, which makes it possible to perform the phosphate coating of the base material (9) (9 ') more quickly and reasonably.

Finally, although the treatment tank 1 is shown as being arranged in a straight line in the drawing, when the number of the treatment tank 1 is large, so as to reasonably adjust the space according to the equipment of the treatment tank 1, Each treatment tank 1 may be arranged in a "b" shape or a "c" shape, and in this case, the transfer rail 2 may be arranged along the same direction as the treatment tank 1.

In addition, what has been described above is that the transfer rail device 10 according to the present invention is applied to the phosphate coating treatment, the transfer rail device 10 according to the present invention other surface treatment other than the phosphate coating treatment, for example metal Of course, it can be applied to the surface coating, coating or plating treatment of the base material, it is also to be understood that this is naturally included within the scope of the technical idea to be pursued.
