Description

Application method and apparatus for applying adhesive liquid of iron ring for oil seal {a application method and system of oil seal inor ring adhesive liquid}

The present invention relates to a method and apparatus for applying an adhesive liquid of an iron seal for an oil seal, and more particularly, to automate the entire process of applying and drying an adhesive liquid used for adhering rubber to an iron ring, a component of an oil seal, on the surface of an iron ring. The present invention relates to a method and apparatus for applying an adhesive liquid for an iron seal iron ring, which enables the coating amount of the adhesive liquid to be constant on the surface of the iron ring to increase the yield while minimizing the defect rate.

Conventionally, after injecting the adhesive liquid into a certain liquid bath, the operator deposits the iron ring to be applied daily by directly inside the adhesive liquid, and then applies the adhesive liquid to the iron ring for a predetermined time and recovers it. Completion of the work twice was a common work method, and in some cases, the product was produced by automating part of the work method such as product transfer and adhesive liquid application.

In the conventional method, since the worker has to handle the whole process directly, it is difficult to produce a uniform quality and a certain amount of products because the working conditions are different due to the worker's work ability and the accumulation of fatigue, and to maintain a certain temperature in a closed space. The diluent must be evaporated by heating the iron ring. The conventional thermal drying method uses a heater, and the temperature difference is severe by the distance unit of the preheating heater, so that the iron ring is not uniformly dried but is uniformly dried. Therefore, the main cause of weakening the adhesive strength with rubber when the product is finished, and the diluents of the adhesive liquid evaporate while the iron rings are in contact with each other, so that the iron rings closely adhered to each other, so that the iron rings should be separated after the work is completed. There have been problems such as additional unnecessary processes that occur, Although some work processes were replaced by automated facilities, there were problems such as double loss such as neglect or disposal of automatic facilities due to failure of conveying and heat-drying conditions for each process of iron ring.

Due to these problems, production facilities should be installed on the basis of the maximum production volume, accompanied by financial loss and labor waste due to excessive production installation and inefficient maintenance, and due to the environmental pollution of the workplace due to the gas generated during work. There has been a considerable risk to the health and safety of workers, and productivity has been reduced due to the price drop caused by the deterioration of the quality of the product after the completion of production, which has been accompanied by waste of time and financial loss. It is not present.

Accordingly, in the present invention, in order to eliminate the above problems, the transfer of the iron ring and the application and drying of the adhesive ring are performed for each process of the facility so that the application of the adhesive liquid to the iron seal iron ring becomes uniform and uniform. It was completed as a technical task with the focus on making an automated facility to work efficiently to minimize the production time and reliably produce high quality products.

The method of applying the adhesive liquid of the iron ring for oil seals of the present invention is roughly described as a product introduction process, adhesive liquid application process, transfer and rotation process, cold drying process, hot air drying process, product discharge process and chain transfer process;

It transfers the iron ring put in a certain container to the product input device of the product input process and injects it into the adhesive liquid tank by using the lift device, guide device, and transfer clamp of the adhesive liquid application process, and uses the application clamp to apply the adhesive liquid evenly on the iron ring. Rotate the container and transfer it to the cold drying process after the application is completed. The applied adhesive liquid is removed by evaporating the diluent of the adhesive liquid with a blower at normal temperature, and the product is dried inside with the door and outlet door of the hot air drying process In order to prevent the iron rings from sticking together due to the even evaporation of the diluent and the even drying of the adhesive, the container containing the iron rings is transported and rotated in order to prevent the adhesion of the iron rings to each other. The device is operated in parallel, and the dried iron ring is removed from the lift device in the product discharge process. The product is transferred to the product input device by seating on the upper part of the chain belt of the chain transfer process by using the slide device. This process is completed twice to complete the operation of applying the adhesive to the iron seal ring.

The above is only a schematic and comprehensive process flow description, which will be described in detail with reference to the accompanying drawings of a detailed description, specific configurations, and operations for each process.

First, the product input process is a post-process by seating on the upper portion of the transport vehicle 12 in the state in which the iron ring is inserted into the container (A) having the locking shaft (A1) on both sides in the center aligned with the product chain transfer device (7) It is carried out through the following feeding apparatus 1 as a process of transferring to a phosphorus adhesive liquid application process.

That is, the input device 1 is installed by the rail 11 on the bottom of the bottom fixed cylinder 13 in the center and fixed to the cylinder roller 14 to the carriage 12 seated on the upper rail 11 Configure.

The container A having the iron ring built in the above-described configuration is transferred from the chain transfer device 7 to be seated on the upper portion of the transport vehicle 12, and then the cylinder rod 14 is reversed so that the container A is applied to the coating device 20. The transfer clamp 23 is to be transferred to the lower portion of the transfer process to support the smooth liquid coating process is made.

The adhesive liquid applying process is to transfer the container (A) containing the iron ring supplied in the above-described product input process to the adhesive liquid tank 25 by the forward and backward transfer / vertical transfer and clamping process to apply the adhesive liquid with the rotation process, and then It is carried out through the following coating apparatus 2 as a process of transferring to the cold drying process which is a process.

That is, the applicator 2 is a device for applying the adhesive liquid to the iron ring through the conveying, depositing, and rotating operations of the iron ring by using the lift device 22, the guide device 21, and the clamp device 20. As shown in the figure, the cylinder 21a is fixed to the upper part, and the guide device 21 is provided so that the left and right conveying is possible, and the sprocket 22s and the channel 22c are mounted on the lower part thereof, The lifting device 22 is configured to be easily moved up and down, and the lower side has a transfer clamp 23 clamped by the operation of the cylinder 20a and a moder 24M and a chain 24c mounted on one side of the container. Each of the application clamps 24 configured to rotate the locking shaft A1 of (A) constitutes the clamp device 20 and is provided so that the adhesive liquid tank 25 is seated on the upper rail fixed to the lower floor thereof. And to configure the blower 26 on the upper one side.

Since the stroke distance of the cylinder 21a is constant, the guide device 21 configured as described above can be easily and quickly transferred since the left and right transfer points are always constant and accurate, and the lift device 22 is the motor 22M. The motor 22M, which can be reversed / reversed, transfers the clamping device 20 up and down by the structure of the sprocket 22s and the channeling 22c according to the operation direction, and also raises and lowers regardless of the elevation position. If necessary, it can be transferred to a desired position, and the clamp device 20 rotates the container A while the container A having the locking axis A1 is easily and easily detached, and the iron ring in the container A is rotated. When the cylinder loader 20b is moved forward, the clamping is terminated. When the cylinder rotor 20b is reversed, the clamping is performed to fix the locking shaft A1 of the container A. The motor 24M Operation) The container A rotates due to the locking shaft A1 of the container A mounted on the application clamp 24 by the surface chain 24c, and whether or not the container A rotates is determined by the operation of the motor 24M. It is determined by the conditions, so that it is possible to operate freely regardless of the overall operation.

The above-described guide device 21, the lift device 22, the clamp device 20 and the adhesive liquid tank 25 provided on the lower rail are operated as follows to apply the adhesive liquid to the iron ring for oil seal. .

That is, the container A with the iron ring introduced from the feeding device 1 is clamped with the transfer clamp 23 to be raised to the lift device 22, and the guide device is advanced to the upper portion of the adhesive liquid tank 25 and then the lift device. After descending to (22) and deposited in the adhesive liquid tank 25, the clamping is released and raised, and then the transfer clamp 23 is reversed again.

At this time, the application clamp 24 is lowered to the upper position of the adhesive liquid tank to clamp the container A, and then lift the container A with the lift device 22 so as not to close the bottom of the adhesive liquid tank 25, and then the motor ( 24M), apply the adhesive liquid to the iron ring while rotating the container (A), and after the completion of the application, lift the lift device 22 completely to stop the adhesive liquid applied to the iron ring to free-fall, and then after a certain time Cold air is applied to the blower 26 to evaporate and solidify the diluent of the adhesive liquid applied to the iron ring, and then forward the transfer to the guide device 21 and stop the operation of the motor 24M of the application clamp 24. After stopping the rotating operation, the lift device 22 is lowered and seated on the upper part of the transport and rotation device provided in the cold drying process, and after the clamping is released, the lift device 22 is raised to move backward to the guide device 21. Application of adhesive solution Complete the process.

This not only prevents the adhesive liquid from being buried in the apparatus other than the adhesive liquid tank 25, but also prevents the intestines from entering the entire process, and also keeps the working environment more clean. Also, the transfer clamp 23 and the application clamp 24 is to raise and lower by the upper lift device 22 to operate the clamping work at the same time to increase the efficiency to enable different clamping work in one lifting operation.

The transfer and rotation process is carried out by rotating and distance transfer repeatedly in the state in which the coated iron ring in the coating device 2 is embedded in the container A, thereby quickly and accurately performing the cold drying process, the hot air drying process, and the product discharge process. It is carried out through the following conveying and rotating device 3 as an automatic conveying process that allows to proceed.

That is, the conveying and rotating device 3 is formed in the lower part of each device, such as the cold drying device 5, the hot air drying device 6, and the discharge device 7, as shown in FIG. As described above, the transfer device 30 and the rotation device 40 are configured to be coupled to each other.

As shown in FIG. 6, as shown in FIG. 6, a plurality of feed rollers 32 supported by a bearing 31 are fixedly disposed, and a catching piece operated by a catching pin 33 and a fixing pin 34 thereon. The fixed roller 37 is attached to one side of the feed shaft 36 in which a plurality of the feed shafts 35 are mounted at regular intervals, and the feed roller 3 is connected to the feed motor 3M and the connecting shaft 38 of the drive box 3B. It is made by fixing to the chain 3c connected to the sprocket 3s respectively comprised in 32.

This is because when the feed motor 3M rotates the feed motor 3M forward and reverse as the forward and reverse motor, the chain 3c connected to the sprocket 3s moves and is transported by the fixed piece 37 fixed to the transfer chain 3c. The shaft 36 moves forward by the feed roller 32. At this time, as shown in (a) of FIG. 7, the container A in which the iron ring is embedded is seated on the rotating roller 41 and the feed shaft ( 36 and the predetermined distance is maintained so that the engaging piece 35 is supported by the fixing pin 34 to be caught in the lower part of the container A and fed together, and the feed shaft 36 is rotated when the feeding motor 3M is reversely rotated. In this case, as shown in (b) of FIG. 7, since the lower weight of the locking piece 35 is lighter than the weight of the container A, the locking piece 35 rotates to pass through the container A. Only the feed shaft 36 is to be reversed, which is a plurality of engaging pieces 35 are mounted on the feed shaft 36 at regular intervals in each of the drying process and discharge process Since it is made uniformly, it is possible to obtain the effect that several processes are performed at once by one process. The connecting shaft 38 is formed by connecting the transfer motor 3M and the feed shaft 36 without connecting the chain 3c. The purpose is to prevent the heat released in the hot air drying process described below from being transferred to the transfer motor 3M on the transfer shaft 36.

In addition, the rotary device 40 is also fixed to the bearing 43 of the fixed plate 42 on both the left and right sides of the rotary roller 41 at regular intervals about the feed shaft 36 is supported by the support roller 44, The rotary motor 4M for rotating the rotary roller 41 in the drive box 3B provided on one side is configured by a sprocket 4s and a chain 4c.

The rotating device 40 configured as described above rotates the container A by rotating the rotary motor 41 when the container A having a built-in ring is seated on the rotating roller 41. At this time, as shown in Figure 8, the support roller 44 supports the maintenance of the interval of the rotation roller 41 to facilitate the rotation of the container (A) and the transfer motor (4M) is the container while the feed shaft 36 is advanced It stops only when conveying (A) to make smooth conveying.

This is a very effective and important work method to prevent the sticking of the product by the rotation when the iron ring passes through the cold drying device and the hot air drying device to produce better quality products.

The cold drying process is a hot air drying of the diluent of the adhesive liquid remaining without evaporation in the adhesive liquid application process at a normal temperature of the adhesive liquid applied to the iron ring embedded in the container (A) where the application is completed in the coating device (2). The process of complete evaporation and removal before entering the apparatus 6 is carried out via the cold drying apparatus 5 described below.

The cold drying device (5) is as shown in Figure 9 of the adhesive liquid applied to the iron ring embedded in the container (A) in the course of the transfer proceeds at room temperature in the upper portion of the transfer and rotation device (3) It is a device without special components that naturally evaporates the thinner.

That is, when the adhesive liquid diluent remains when the adhesive liquid applied to the iron ring formed in the hot air drying process is solidified, a gas is generated due to the diluent and the gas is not burned and remains in the drying furnace 60 of the hot air dryer 6. It is an important factor to weaken the adhesive strength after solidification, which is to prevent this in advance.

The door (63) and the discharge door (64) operates the cylinder (66) only when the container (A) with built-in iron ring enters and exits the drying furnace (60) by the product transfer device (3). As it rises and opens, and when entry / exit is completed, it is always lowered to prevent heat from being released to the outside during hot air drying. The up / down operation of the door 63 and the discharge door 64 is performed by the transfer device 30. Always works simultaneously with forward feed.

In addition, the heater furnace 67 is configured in the upper portion and the air outlets 62 are provided to prevent damage to the equipment due to the direct heat of the heater 61 and to prevent the iron ring from being directly exposed to the iron ring. In addition, by maintaining the most suitable temperature required by evenly passing the hot air through the vents (62), it is possible to operate the optimal conditions while reducing the heat loss as much as possible.

In other words, the purpose of the first drying is to remove the foreign matter remaining in the iron ring and to have the coating force on the iron ring so that the foreign material that is not removed is not removed during use.A high temperature of 200 ° C is required, and the purpose of the second drying is applied to the iron ring.
