Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically adjusts the inner peripheral surface of a seal component adhered to a main body component in a process of assembling a bearing component for rotatably supporting a shaft of an office automation equipment. The present invention relates to a device for cleaning an inner peripheral surface of a seal part for cleaning.

[0002]

2. Description of the Related Art The above-mentioned bearing parts include those of a type composed of a cylindrical main body part and a ring-shaped seal part (see FIG. 8). It is generally assembled by inserting and adhering a seal part to the main body part molded in (1). For example, in such a case, conventionally, an operator manually inserts a seal component into the bearing body component and adheres the same, but since such an operation is a simple repetitive operation, automation or labor saving is performed. It is desirable to do.

Further, if such a bonding work is automatically performed by a dedicated device, even if a part of the adhesive is adhered to the sealing material or is not adhered when the sealing material of the sealing component is made of felt, for example. The vaporized gas of the solvent contained in the adhesive may come into contact with the seal material, which may cause the seal material to harden and deteriorate quality. It is advisable to clean and rub the surface.

[0004]

SUMMARY OF THE INVENTION A first object of the present invention is to clean the inner peripheral surface of the above-mentioned seal component automatically, and further, to simplify the structure. Is to provide.

It is an object of the present invention to provide an inner peripheral surface cleaning device for a seal component, which is suitable for combination with a device which holds at equal intervals and conveys by a constant pitch.

A third object of the present invention is to also provide an apparatus for judging the quality of the press-fitted state of the seal component adhered in the work body.

[0007]

In order to achieve the above-mentioned first object, the inner peripheral surface cleaning device for a seal component according to the present invention comprises: a) an upper stage in a cylindrical work which is intermittently conveyed by a predetermined pitch. A device for cleaning the inner peripheral surface of an annular seal part press-fitted into, b) consisting of a clamp mechanism for the work, and a cleaning mechanism for inserting and rotating in the opening of the seal part in the work, c ) The clamp mechanism disposes a pair of clamp claws that face each other across the conveyance path at the workpiece temporary stop position so as to be openable and closable, and biases the clamp claws with each other in a closing direction by a spring. The clamp claw open / close cam is rotatably provided, and d)
The cleaning mechanism disposes a mounting base of the cleaning member so as to be able to move up and down above the transport path at the clamp mechanism installation position, and mounts a rotation drive means on the mounting base to mount the rotation shaft on the rotary shaft. A truncated frustoconical cleaning member that can be inserted into the opening of the seal part is arranged downward and connected, e)
The rotation of the opening / closing cam and the raising / lowering of the mounting base are configured to be performed by a common drive device in association with the conveyance of the work.

With regard to this cleaning device, as described in claim 2, f) one end of the wire is fixed to the mounting base, and the cleaning is performed at the other end of the wire via a pulley provided above the mounting base. A weight is attached to reduce the downward load of the member, and g) an elevating cam of the mounting base is rotatably provided in the vertical direction, and the rotation of the elevating cam and the rotation of the opening / closing cam are interlocked. You can

Further, as described in claim 3, h) a guide rod is erected on the mounting base or a support plate integrally provided below the mounting base, and one side portion of the lift plate is attached to the guide rod. A detection rod that is loosely inserted so that it can move up and down, and that the elevating plate is extended from the cleaning position of the seal parts of the work above the work temporary stop position on the transport side by one pitch, and can be inserted to the upper position in the front work. Is loosely inserted into the lift plate so as to be movable up and down, and a locking member is fixedly provided on the upper part of the detection rod. I) A first member is provided on the lift plate laterally (including rear and front) of the locking member. A proximity sensor (including a proximity switch) may be provided, and a second proximity sensor (including a proximity switch) may be provided on the lift plate so as to face above the detection rod.

[0010]

According to the inner peripheral surface cleaning device of the present invention having the above-mentioned structure, the rotating cleaning member is inserted into the opening of the annular seal member press-fitted into the upper stage of the cylindrical work to clean it. Thus, the action of (and sealing material for) the seal component is also provided.

That is, according to the cleaning device, the pair of clamp claws facing each other approach each other by the urging force of the spring by rotating the opening / closing cam by a predetermined angle while the work conveyed on the conveyance path is stopped. Then, the work that is stopped on the transport path is clamped. The mounting table descends in association with the rotation of the opening / closing cam, and the cleaning member also descends as it descends to be inserted into the opening of the seal component in the work.
Since the cleaning member has the shape of a truncated cone, it can be reliably inserted into the opening of the seal component. Also, since the cleaning member is rotating, the inner peripheral surface of the opening of the seal part is cleaned by the cleaning member, and (the seal material of) the seal part is rubbed and unaffected by the solvent of the adhesive. Curing of (the sealing material of) the sealing component is prevented.

After the cleaning work of the inner peripheral surface of the seal component is completed in this way, the mounting table rises and the cleaning member comes out of the opening of the seal component. The workpieces on the conveyance path are released from the clamps by separating from each other against the biasing force. Then, the cleaned work is transported. The rotation of the opening / closing cam is continued during the cleaning work by the cleaning member. Also, since the rotation of the open / close cam and the raising / lowering of the mounting base (cleaning member) are performed by a common drive device, the two operations (rotation and raising / lowering) naturally interlock only by adjusting the speed ratio with a gear mechanism or the like.

According to the cleaning device of the second aspect, the contact pressure of the cleaning member with respect to the inner peripheral surface of the seal component can be appropriately adjusted by changing the weight load. Moreover, since the two operations are performed by the rotation of the two cams, it is possible to easily adjust the timing of the operations of the both by only adjusting the rotation speed ratio by a gear mechanism or the like.

According to another aspect of the cleaning device of the present invention, when the cleaning member (mounting base) descends at the cleaning position of the transfer path, the detection rod is placed on the seal part of the cleaned work which is stopped on the transfer side for one pitch. It descends and abuts. In this state, when the seal component that is press-fitted in the upper stage of the work and adhered is placed at the proper position, the locking member on the upper part of the detection rod is in the range detectable by the first proximity sensor on the lift plate. Since it is located inside, it is detected by the first proximity sensor (the first proximity sensor is ON). Further, since the upper end (top surface) of the detection rod is located below the facing second proximity sensor and is located below the range detectable by the same sensor, it is not detected by the second proximity sensor. (The second proximity sensor is off). As a result, it is confirmed that the seal component is bonded to the regular position in the work (see FIG. 7A).

On the other hand, when the seal part press-fitted into the upper part of the work is lifted from the normal position, the detection rod abutting on the seal part is also lifted slightly above the normal position with respect to the lift plate. , Is in proximity to the second proximity sensor and is detected by the same sensor (second
Proximity sensor is ON). At the same time, since the locking member on the upper part of the detection rod is located within the range detectable by the first proximity sensor, it is detected by the first proximity sensor (first
Proximity sensor is ON). As a result, the floating of the seal component is confirmed (see FIG. 7 (c)). In addition, if the seal component in the work has poor adhesion, when the cleaning member rises after the inner peripheral surface has been cleaned by being inserted into the seal component in the work at the cleaning position, the seal component will adhere to the cleaning member. It may come out of the work, but in this case, the tip of the detection rod is inserted to the upper stage of the work. Therefore, it is not detected by either the first proximity sensor or the second proximity sensor (the first proximity sensor and the second proximity sensor are OFF). As a result, it is confirmed that the seal component is not pressed into the work (see FIG. 7 (b)). When there is an abnormality in these two cases, the operator may be notified by a notification means such as a buzzer.

As described above, when it is confirmed that the seal component is adhered to the proper position in the work, when the cleaning member (mounting base) is raised at the cleaning position, the lift plate is also raised. By doing so, the lifting plate is locked by the locking member above the detection rod, and the detection rod rises above the seal component of the work and separates, so that the work on the transport path can be transported.

In the apparatus of the present embodiment constructed as described above, the cleaning operation of the inner peripheral surface of the seal part D and the press fit state determination of the seal part D are performed as follows.

First, regarding the cleaning operation, according to the cleaning device 3, the work A conveyed on the rail 2 is stopped at the cleaning position by the conveying pin 73 of the horizontally rotating conveying member 71 of the conveying device 70. Almost at the same time, the opening / closing cam 33 of the clamp mechanism 3B rotates by a predetermined angle, and the moving blocks 23 facing each other approach each other by the urging force of the compression spring 29 until they come into contact with the stopper 24. As a result, the pair of clamp claws 20 approach each other by the biasing force of the spring 29, and clamp the work A on the rail 2.

By rotating the eccentric cam 16 in conjunction with the rotation of the opening / closing cam 33, the mounting base 6 of the cleaning mechanism 3A is
Is lowered by its own weight, and the cleaning pin 5 is lowered together with the mounting base 6 and inserted into the opening of the seal component D in the work A.
The cleaning pin 5 is frustoconical in shape, and the bearing support plate 10 that supports the rotating shaft 8c that connects the cleaning pin 5 is used.
Since the bearing 11 in the recess 12 is horizontally movable, the cleaning pin 5 is reliably inserted into the opening of the seal component D. Thus, the cleaning pin 5 inserted into the seal component D
Is rotated by the drive motor 8, the sealing component D
The inner peripheral surface of the sealing material E is cleaned by the cleaning pin 5, and the sealing material E of the sealing component D is massaged and unraveled.
The sealing material E is prevented from being hardened under the influence of the solvent of the adhesive.

When the cleaning work of the inner peripheral surface of the seal part D is completed, the mounting base 6 is raised by the eccentric cam 16 and the cleaning pin 5 is pulled out from the seal part D. After that, the opening / closing cam 33 rotates by a predetermined angle, so that the moving blocks 23 facing each other are separated from each other against the biasing force of the compression spring 29. As a result, the pair of clamp claws 20 are separated from each other, and the clamp of the work A on the rail 2 is released. In this state, the cleaned work A on the rail 2 is transported by one pitch by the transport pin 73 of the transport member 71 that horizontally swivels the transport device 70.

Next, regarding the work of determining the press-fitted state of the seal component D, before the cleaning work by the cleaning device 3, the bearing support plate 10 is used.
And the ascending / descending plate 51 are also lifted upward by the bearing support plate 10. For this reason, as shown in FIG.
Is located above the work A on the rail 2. Then, the work by the cleaning device 3 is started, and as the bearing support plate 10 descends together with the mounting base 6, the elevating plate 51 descends, and the detection rod 52 descends to seal the seal part D of the cleaned work A. The tip portion 52a is placed on.

In this state, when the seal component D press-fitted in the upper stage of the work A and adhered is press-fitted in the regular position, the locking member 54 of the detection rod 52 can be detected by the first proximity sensor 56. Since it is located within this range, the first proximity sensor 56 detects it, and the first proximity sensor 56 is turned on. In this state, the detection rod 5
The top surface of No. 2 is located below the range detectable by the second proximity sensor 57 facing the second proximity sensor 57, and thus is not detected by the second proximity sensor 57 and the second proximity sensor 57 is OF
It is F. Thus, that is, when the first proximity sensor 56 is in the ON state and the second proximity sensor 57 is in the OFF state, it is determined that the seal component D is bonded to the regular position in the work A (FIG. 7 ( See a)).

On the other hand, when the seal part D press-fitted into the upper part of the work A is in a state of being lifted from the normal press-fit position, the detection rod 52 abutting on the seal part D is in the normal position with respect to the lift plate 51. Located slightly above. Therefore, the top surface of the detection rod 52 is detected by the second proximity sensor 57, and the second proximity sensor 57 is turned on. At the same time, the locking member 54 of the detection rod 52 also moves to the first proximity sensor 56.
Since it is located within the range that can be detected by, the first proximity sensor 56 detects the first proximity sensor 56
Become N. As a result, that is, when both the first proximity sensor 56 and the second proximity sensor 57 are turned on, it is determined that the seal component D is lifted (see FIG. 7C).

Further, when the seal component D in the work A is poorly press-fitted or the seal component D is poorly adhered, the inner peripheral surface is cleaned by the cleaning pin 5 of the cleaning device 3, and then the cleaning is performed. When the pin 5 is pulled up, the seal part D may be pulled out from the work A together with the cleaning pin and may come out. When the seal part D is not press-fitted, the tip portion 52a of the detection rod 52 is located in the upper part of the work A. Descend until it touches. Therefore, the top surface of the detection rod 52 moves away to a position that cannot be detected by the second proximity sensor 57, and the second proximity sensor is turned off. The locking member 54 is also located below the range detectable by the first proximity sensor 56, and the first proximity sensor 56 is also turned off. As a result, that is, when both the first proximity sensor 56 and the second proximity sensor 57 are turned off, it is determined that the seal component D is not press-fitted into the work A (see FIG. 7B).

In the latter two cases, the seal part D is used.
Since the press-fitting is abnormal, the operator may be notified by a notification means such as a buzzer to remove the defective product.

When the above determination work is completed, the cleaning work by the adjacent cleaning device 3 is also completed almost at the same time. Therefore, when the bearing support plate 10 of the cleaning device 3 is lifted together with the mounting base 6, the lift plate 51 is also lifted. To do. Then, the lift plate 51 is locked by the locking member 54, the detection rod 52 is lifted and separated above the tip part 52a of the seal component A, so that the work A on the rail 2 becomes movable,
It is further transported by the transport pin 73 of the transport member 71.

Particularly, in the above-described bearing component assembling apparatus, all the operations are performed by the single drive motor 41 of the drive apparatus 40, except that the rotation drive motor 8 of the cleaning pin 5 of the cleaning apparatus 3 is performed. Since the operation is performed, each operation can be easily interlocked with each other, and the structure of the entire drive mechanism can be simplified.

As is apparent from the above description,
The inner peripheral surface cleaning device for a seal component of the present invention has the following effects. That is, 1) The inner peripheral surface of the seal part can be automatically cleaned, and the structure is simple. In addition, since the sealing parts are cleaned while the work is clamped, it can be reliably cleaned, and also has the function of rubbing and unraveling the sealing member (the sealing material), and the sealing material is hardened by the gas evaporated from the solvent of the adhesive. Can also be prevented.

2) In the apparatus of claim 2, the contact pressure of the cleaning member with respect to the seal component can be easily adjusted by changing the load of the weight, and the vertical movement of the cleaning member and the clamping and releasing of the work can be performed by the cam. Since it is performed by rotation, it can be easily interlocked with a work transfer device or the like.

3) According to the apparatus of claim 3, it is possible to automatically judge the quality of the press-fitted state of the seal component adhered in the work body, and the raising and lowering operation of the detection rod is performed by using the raising and lowering operation of the cleaning device. Since it is performed, no special drive device is required and the structure is simple. Moreover, since the two proximity sensors detect and detect the respective surfaces of the detection rod and the locking member, it is possible to detect the points more accurately and reliably than the conventional general device that detects the points. The quality can be accurately judged.
