Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention allows a flexible hose such as a rubber hose to be inserted and connected to a bent pipe for hose connection which can be connected to a connected portion provided in an automobile engine or the like. And a device for applying the liquid agent.

(Prior Art and Problems to be Solved by the Invention) As a method for applying a liquid agent to the surface of an object to be coated, a hand coating method, a spraying method, a dipping method or the like has been generally used, but a fuel hose of an automobile or the like. As a method for applying the liquid agent to the bent pipe for hose connection that can be fitted with the flexible hose, the hand coating method and the spraying method are not suitable. Therefore, as a method for applying a liquid agent to such a bent tube for connecting a hose, a dipping method has been generally used in the past. FIG. 17 shows a specific example. In this example, the curved pipe for hose connection is hung and conveyed by the conveyance means 200, and the curved pipe for hose connection is immersed in the liquid agent 202 on the way.

By the way, in the case of this dipping method, since the hose connecting curved pipe is dipped in the liquid agent while maintaining the posture in a constant posture, for example, there is a difference in the applied amount of the liquid agent between the portion extending relatively in the vertical direction and the portion extending in the horizontal direction. Is likely to occur. That is, in the portion extending relatively in the vertical direction, the adhered liquid agent flows down the surface along the surface, while in the portion extending in the horizontal direction, there is no such movement of the liquid, so that an excessive amount of liquid is finally added to the same portion. Liquids tend to adhere and cause dripping. Therefore, in the case of such an immersion method, the film thickness of the liquid agent on the curved pipe surface is likely to be nonuniform.

By the way, some liquid agents are likely to be foamed when they are later subjected to baking or the like. Therefore, such foaming occurs in a portion where liquid dripping occurs or a portion where the film thickness becomes thick as described above. In order to prevent this, air is blown onto the curved pipe surface after the immersion in the liquid agent to remove the excessively adhered liquid agent or equalize the film thickness.

However, this work has to be done manually by an operator. Therefore, if such a process is required, the liquid agent application process cannot be mechanized or automated, and the product quality becomes unstable. easy. As described above, the portion where the film thickness is likely to be thick is not constant depending on the type and shape of the product, and since the operator visually confirms the air blowing, variations are apt to occur.

In addition, if the liquid agent is blown off by blowing air, if the liquid agent is harmful, it causes a problem in working hygiene, and a large exhaust gas treatment device is required, resulting in a large scale of the device.

(First Solving Means) The present invention has been made to solve such a problem, and its gist is a bent pipe having a hose insertion portion into which a flexible hose can be inserted. A method for applying a liquid agent to the outer peripheral surface of the bent pipe portion of the bent pipe for hose connection, which comprises a connecting portion having an opening hole fixed to the rear end of the bent pipe portion, After masking the hose insertion portion of the pipe with a stopper or a cap, the opening of the connecting member fixed to the bending pipe for connecting the hose to the protrusion of a holding member having a protrusion that is vertically and rotatably supported After fitting and fixing the holes, the supporting member is then lowered by a predetermined distance and rotated by a predetermined angle to leave at least the bent pipe portion in the liquid agent leaving the opening hole of the connecting member of the bent pipe for hose connection. Dip and then in the liquid And / or while pulling up the holding member, rotate the holding member so that the hose insertion portion is substantially downward, apply the liquid agent to the bent pipe portion, and then bend the hose connecting pipe. The method for applying a liquid agent to a bent pipe for hose connection is characterized in that the applied liquid agent is dried with the hose insertion portion thereof being substantially downward.

(Action and Effect of First Solving Means) That is, in the present invention, the curved tube for hose connection is not immersed in a fixed posture in the liquid agent, but is processed while being rotated, and finally the tip thereof is I made it face down. Here, "downward" means not only vertically downward,
It also includes the case where a predetermined angle is formed with respect to the vertically downward direction.

With this configuration, the liquid agent adhering to the curved pipe portion surface of the hose-connecting curved pipe can sequentially flow downward along the surface of the curved pipe for hose-connecting, that is, to the tip side, so that the liquid agent partially flows. There is no place where liquid drops occur, that is, a place where the amount of the liquid agent attached partially increases, so that the liquid agent can be applied to the curved pipe surface of the hose connecting curved pipe in a uniform thickness.

Therefore, it is possible to avoid the phenomenon of foaming locally in a thick film portion when the liquid agent is applied with baking after being applied. Therefore, it is not necessary to perform the air blowing process as described above. As a result, it becomes possible to mechanize and automate the liquid agent application process, solve the problems of the work environment deterioration due to the above-mentioned air blowing, the problems of installing an exhaust gas treatment device, etc., and make the liquid agent application device compact. Is possible.

In addition, by appropriately selecting the pattern of rotational movement for the curved tube for hose connection according to the type and shape of the product, and making the same pattern of movement for the same type of product, all products can be operated under the same conditions. It can be processed and the product quality is stabilized.

In addition to the above, the method of the present invention utilizes the opening hole of the connecting member of the bent pipe for hose connection in which the hose insertion portion of the bent pipe for hose connection is masked with a plug or a cap, and the hose insertion portion is masked with a plug or a cap. Since the bent pipe for hose connection is held by the holding bar (holding member),
The bent tube for hose connection can always be held in the same posture, and the bent tube for hose connection can be moved in the same pattern just by masking the hose insertion part formed at the tip of the bent tube for hose connection. As a result, at least the bent pipe portion can be immersed in the liquid agent while leaving the opening hole of the connection member, and therefore the liquid agent can be stored in the bent pipe for hose connection without troublesome masking work for various connection members having complicated shapes. Can be prevented from entering, and the liquid agent can be economically applied to the outer peripheral surface of the bent pipe portion requiring rust prevention without leakage.

(Second Solution Means) A second solution means of the present application relates to a liquid agent applying device, and the gist thereof is a bent pipe portion having a hose insertion portion at which a flexible hose can be inserted, and the bent portion. A liquid agent applying device for applying a liquid agent to the outer peripheral surface of a hose connecting bent pipe part, which comprises a connecting member fixed to the rear end of the pipe part, and a holding part for holding the connecting member of the hose connecting bent pipe. An independently-separated rod-shaped holding member, a conveying device that conveys the holding member in a horizontal direction with its axis being horizontal, and an end of the rod-shaped holding member whose axis is supported horizontally is rotatable. And a support device that supports the support device so as to be able to move up and down, a liquid agent tank that stores a liquid agent disposed below the rod-shaped holding member supported by the support device, and the rod-shaped holding member supported by the support device. Raise and lower,
Thus, it is possible to rotate the elevating device, which is immersed in the liquid agent up to a position near the connecting member of the bent tube for connecting the hose, and is raised from the liquid agent, and the rod-shaped holding member supported by the supporting device, by a predetermined angle. And a rotatable device capable of rotating, and a liquid agent applying device for a bent pipe for hose connection, which comprises:

(Operation and Effect of Second Solving Means) In the device of the present invention, when the connecting member of the bent pipe for hose connection is held by the holding member, the holding member is lowered by the elevating device, and the bent pipe of the bent pipe for hose connection is lowered. The part is immersed in the liquid agent. After that, the holding member is raised by the elevating device and the bent pipe portion of the hose connecting bent pipe is pulled up from the liquid agent.

Therefore, according to the apparatus of the present invention, the method according to the above first solving means can be suitably implemented.

Here, the slider 124, the holding body 134, and the core body 136 form an example of the “supporting device” in the gist of the present invention.

Next, the procedure for applying the liquid agent to the work 14 with this apparatus will be specifically described along with the operation of the apparatus.

First, the holding bar 12 is attached to the support plate 32 of the first lateral transfer device 18.
The work 14 is set on the holding bar 12 as shown in FIG. 3 while being engaged and supported by the engagement groove 34 of FIG. FIG. 14 (A) shows this state.

The holding bars 12 supported on the engagement grooves 34 are sequentially fed through the engagement grooves 34 one by one by the first transport unit 28. The specific operation is as follows. That is, in FIG. 5, when the vertical drive cylinder 50 first operates to pull in the rod 52, the rotary shaft 46 is rotated and the drive plate 42 is raised.
Along with this, the circulation member 36 is lifted together. At this time, the circulation member 36 places the holding bar 12 supported by the support plate 32 on the engagement groove 38 and lifts it up. Then, the lateral drive cylinder 56 operates to move the circulation member 36 forward by a stroke corresponding to the pitch p ₁ .
Subsequently, when the circulation member 36 is lowered by the vertical drive cylinder 50, the holding bar 12 supported thereby is placed on the engagement groove 34 of the support plate 32. Ie holding bar 12
Is sent forward by one pitch p ₁ of the engaging groove 34.

The holding bar 12 and the work 14 held by the holding bar 12 are successively fed by one pitch of the engaging groove 34 by repeating this operation. Then, at the position of the through grooves 60, 62 provided in the support plate 32, that is, at the position above the liquid agent tank 27 and the cleaning liquid tank 29, the inside of the liquid agent tank 27 of the workpiece 14 or the cleaning liquid tank 29 by the immersion treatment device 31, 33. Immersion treatment is performed. The procedure is as follows.

First, as shown in FIG. 13, the core body 136 is advanced to hold the end portion of the holding bar 12. Then, the mini-cylinders 64, 6 provided on the support plate 32 of the first lateral transfer device 18.
The blocks 68 and 70 are pulled in by 6 and the through grooves 60 and 62 are opened. When the through grooves 60 and 62 are opened, the slider 124
Is lowered and the work held on the holding bar 12
14 is immersed in the liquid agent tank 27 or the cleaning liquid tank 29.

The immersion treatment of the work 14 in the liquid agent tank 27 by the immersion treatment device 31 is performed as follows.

The work 14 held on the holding bar 12 as described above is
As shown in the figure (A), the tip portion 14b is initially directed downward, but before being immersed in the liquid agent, the tip portion 14b is first rotated by a certain angle so that the tip portion 14b is directed obliquely upward. (See (B)). That is, the posture is changed so that the straight portion of the connection fitting 14c becomes substantially horizontal. The work 14 is lowered in this state, and the portion up to the position near the connection fitting 14c is immersed in the liquid agent (see (C)). This work
In the case of No. 14, the female screw hole is formed in the connection fitting 14c, but the opening of this female screw hole is not immersed in the liquid agent, and therefore the opening portion of this female screw hole is not masked. On the other hand, a rubber cap is fitted to the tip end portion thereof in order to prevent the liquid agent from adhering to the surface and entering the liquid agent into the pipe.

Next, the work 14 is rotated 90 ° so that the tip portion is immersed in the liquid agent, and the liquid agent is applied to the tip portion where the liquid agent was not applied in the state of (C) (see (D)).

Then, the work 14 is pulled up from the liquid and further rotated by a predetermined angle (for example, about 30 ° to 45 °), and finally the tip portion 14b is in a downward posture (see (E)). That is, in this example, the work 14 is sequentially immersed in the liquid agent from the base end to the tip end portion. Therefore, since the liquid agent attached to the surface of the work 14 sequentially flows toward the tip side by gravity, the liquid agent does not remain excessively attached to a certain place.

It should be noted that FIG. 15 shows a procedure for dipping a liquid agent into a work 17 of another type. In this example, the bent pipe part of the work 17
First, the connecting member 17c is brought into the state of (A) according to the bent shape of 17a.
The work set using the opening hole of (B),
As shown in (C), it is rotated by a certain angle and immersed in the liquid agent, and then it is pulled up from the solvent and
It is rotated by 30 ° to 45 ° so that the straight portion of the tip portion 17b finally faces downward (see (D)). Even in this case, it is possible to prevent a large amount of the liquid agent from partially adhering to the surface of the work 17.

Now, when the work 14 (17) is immersed in the liquid agent, the work 14 is then raised together with the holding bar 12. At that time, the holding bar 12 is provided with the support plate 32 and the through-grooves 60, 7 of the circulation member 36.
It enters 2 and is then transferred to the circulation member 36. The circulation member 36 that has received the holding bar 12 makes a circular motion along the locus of the parallelogram as described above, and sequentially feeds the holding bar 12 one pitch at a time to carry it forward.

As described above, the first carrying unit 28 and the second carrying unit 30 both carry the holding bar 12 forward by the same operation, but the feed pitch is the same as the first carrying unit 28 and the second carrying unit 30. It's different. That is, the second transport unit 30 sequentially feeds the work 14 at a pitch p ₂ shorter than that of the first transport unit 28. This is because immediately after the work 14 is dipped in the liquid, the liquid drops from the surface of the work 14, and immediately after the work 14 is dipped in the liquid, the work 14 is dipped.
The feed pitch before and after is widened to prevent the dripping liquid agent from dropping on the surface of the work 14 one pitch ahead, while at the stage when the liquid agent has dried to some extent and there is no fear of dripping, Is to shorten the required transport distance. As a result, the occupied space in the front-rear direction of the device can be shortened.

The work 14 is fed forward by the first lateral transfer device 18, and the liquid agent applied during that time is dried. Subsequently, the holding bar 12 is the first vertical transfer device 22 and the delivery device.
It is moved to the second horizontal transfer device 20 by 26, and is then transferred in the horizontal direction and in the direction opposite to the first horizontal transfer device 18,
Meanwhile, the baking treatment of the liquid agent applied to the work surface is performed. When the holding bar 12 reaches the front end (the left end in FIG. 2) of the second horizontal transfer device 20, the transfer device 26 transfers the holding bar 12 and the work 14 to the second vertical transfer device 24, and the work is carried out at a predetermined position. 14 unloading and new work holding bar 12
Is set to. At this point, one cycle of the process of applying the liquid agent to the work 14 is completed.

Although the embodiments of the present invention have been described in detail above, the present invention can be implemented and configured in other modes and modes.

For example, the present invention is applicable when applying a liquid agent to various shapes of hose connecting bent tubes 19, 21, 23 as shown in FIG. 16 and further to other shapes of hose connecting bent tubes. Further, various kinds of liquid agents can be used, and as shown in FIG. 16, the tip portion 19b of the bent pipe portion 19a is
There is no problem even if the method of the present invention is carried out by masking with a cap 11.

Besides, what has been illustrated above is merely an example of the present invention, and the present invention can be implemented and configured in various modes and modes with various modifications made based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
