BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet deburring apparatus for performing a wet deburring.

[0002]

2. Description of the Related Art Conventionally, as a deburring device for removing burrs generated on a plate material by, for example, press working, there is known a deburring device provided with a deburring wheel which rotates orthogonally to a feeding direction of a plate material work. ing. However, such a conventional deburring device is configured to perform deburring by bringing a high-speed rotating deburring wheel into contact with a work conveyed on a conveyor device.
Since no water was supplied to the vicinity of the contact point between the deburring wheel and the workpiece, the deburring was performed in a dry state, and dust generated during this deburring was Since it scatters around and deteriorates the working environment, it is necessary to separately install a dust collecting device to prevent this, so that the cost is increased, and there is a problem that an installation space for the dust collecting device is additionally required. Further, since the dust generated during the deburring process is transported while adhering to the work, a post-processing step for dust removal processing is required, which also causes an increase in cost.

[0003] Further, since the deburring operation is performed, a large amount of heat is generated due to frictional heat during the deburring operation, which has an adverse effect on the work, which may cause deformation of the material and seizure of the deburring wheel. When a large grinding amount cannot be obtained at a time and large deburring work needs to be performed, the deburring operation must be performed in several steps. There was a problem that could not be raised. Further, in the dry deburring operation, there is a problem that the surface roughness of the material is large at the time of finishing because the friction coefficient between the work and the deburring wheel is large.

[0004] Therefore, a wet deburring apparatus has been proposed in which deburring is performed by spraying water near a contact portion between a deburring wheel and a workpiece by a water distribution means in order to perform deburring in a wet manner. I have. And, in the wet deburring apparatus thus proposed, in order to dry and remove moisture from the work on which the wet deburring operation is completed, a draining roller for draining the work downstream from the deburring wheel, The configuration was provided with a hot air supply device that blows hot air onto the work to dry the moisture.

[0005]

However, in the drying device of the wet-type deburring device thus proposed, the hot air supply device particularly includes a heater for heating air to blow hot air to the work and a plate material work. There is a problem that heaters are required in two places, that is, a heater for heating and energy consumption is increased. In addition, the air heated by the heater needs to be guided to the blowing nozzle through the duct and blown to the work, so that there is a heat loss during the passage of the duct, and there is a problem that sufficiently high-temperature hot air cannot be blown. In addition, it is necessary to make contact with the heater for a sufficient time in order to blow out the hot air, so that the wind speed cannot be made too high. As a result, there is a problem that much moisture must be evaporated by the heater, and stains remain as dirt after the moisture evaporates from the work.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention performs deburring of a work at a position above a table provided with a conveyor device for conveying the work in the left-right direction. In a wet deburring apparatus including a deburring wheel and a water pipe for supplying moisture near a deburring operation point, the moisture and deburring debris on the surface of the work are removed downstream of the deburring wheel. And a second water pipe for spraying water to wash out the deburring residue remaining on the work surface is provided downstream of the roller, and a second water pipe is provided downstream of the second water pipe. A draining roller for removing moisture adhering to the work is arranged and provided, and a blowing nozzle for blowing off moisture on the work is arranged downstream of the draining roller. , On the downstream side of the blowing nozzle, it is made by arranging a heater for evaporating off the water on the workpiece.

9c is laid so as to cross the table 3 back and forth, and is connected by a water supply pump 21 and a tube 23;
The work conveyed on the table 3 can be sprinkled with water near the deburring operation point.

A brush roller 25 is disposed on the left side of the C-shaped frame 1 at a position closer to the frame 1 than the left end water pipe 19c, and is driven to rotate by a conveyor driving motor 13 to be conveyed on the conveyor device 11. The workpiece comes into rotational contact with the workpiece and sweeps out dust adhering to the workpiece.

On the left side of the brush roller 25, there are draining rollers 27a, 27b, 27 which are components of the drying device.
c, one of which is a draining roller 2
7a is co-rotating in contact with the conveyor device 11, and the other two draining rollers 27b, 27c are opposed to each other so as to be in contact with each other, and drain the water adhering to the work when the work passes between them. It is supposed to do.

On the sub-conveyor device 15 at the left end of the table 3, a blower nozzle 29 which is a component of the drying device is disposed, and a plurality of heaters 3 which are a component of the drying device.
1 is horizontally arranged in the front-rear direction so as to face up and down with the sub-conveyor device 15 interposed therebetween, and by blowing a wind blown from a blowing nozzle 29 to a work conveyed on the sub-conveyor device 15 first. The water on the work is blown off, and the work is heated by the heater 31 to dry and remove the remaining water.

At the bottom of the table 3 is provided a bucket 33 for receiving water over substantially the entire surface, and a water tank 35 is provided at the lower left of the table 3 so that water collected in the bucket 33 can be collected. The water is drained to the water tank 35. The water tank 35 is provided with a filter paper 37 for filtering out deburring chips and fine powder from the water discharged here. The water stored in the water tank 35 is supplied to the water distribution pipes 19 a to 19 by the pump 21.
c and is supplied to the deburring work section.

The structure of the pinch rollers 9a and 9b is shown in detail in FIGS. 4 to 6, and is fixed to the frame 1 and is provided on the left and right sides of a roller support 39 disposed so as to straddle the deburring wheel 5 from side to side. Pinch rollers 9a and 9b having substantially the same length as the deburring wheel 5 are provided horizontally at the lower end positions in the front-rear direction.

At the rear ends of the pinch rollers 9a and 9b, sprockets 41a and 41b rotating together with the pinch rollers 9a and 9b are provided coaxially. The sprockets 41a, 41 of the pinch rollers 9a, 9b are located at positions surrounding the deburring wheels 5 on the left and right sides of the roller support 39.
Auxiliary sprocket 4 that can rotate freely to correspond to b
3a and 43b are attached. A chain 45 is wound around these four sprockets 41a, 41b, 43a, 43b, and one of the right and left pinch rollers 9a is rotated by frictional contact with the conveyor device 11, so that the chain 45 is rotated. Through the four sprockets 41a, 41b, 43a, 43b
All rotate in the same direction, and as a result, the other pinch roller 9b can also be driven and rotated in the same direction.

Therefore, when a work having a large thickness is conveyed from the right side on the conveyor device 11 and enters between the pinch roller 9a on the right side and the conveyor device 11,
The rotation of the pinch roller 9a is temporarily stopped to separate from the conveyor device 11, but the pinch roller 9b on the left side is kept in contact with the conveyor device 11 and continues to rotate. The pinch roller 9a on the right side of the lever also keeps rotating, so that the workpiece can be moved while being pressed in the direction of the deburring wheel 5. For this reason, since the left and right pinch rollers 9a and 9b rotate independently as in the related art, the work having a large plate thickness cannot be moved to the right pinch roller 9a.
The rotation of the pinch roller 9a is stopped when the pinch roller 9a enters between the a and the conveyor device 11, so that it is possible to prevent a situation in which the work stops here and the material is clogged.

The blowing nozzle 29 which is a component of the drying device
As shown in FIGS. 7 and 8, the sub-conveyor is installed at the left side of the table 3 at a position above the sub-conveyor device 15 in the front-rear direction. Air is blown out onto the device 15. A duct 49 is connected to the blow nozzle 29, and the other end of the duct 49 is connected to a blower 51. The blower 51 is provided on the blower frame 53 and is movable. Therefore, by blowing the wind sent from the blower 51 through the duct 49 to the work on the sub-conveyor device 15 from the outlet 47 of the blower nozzle 29, the moisture adhering to the work can be blown off. This spraying speed is preferably 30 m / sec.

Further, as shown in FIG. 9, drainers rollers 27b and 27c, which are driven to rotate by the conveyor drive motor 13, a blower nozzle 29, and a heater 31 in which a plurality of blower nozzles are vertically arranged. A drying device is configured, and a drying process of the work after the deburring operation of the wet deburring device is performed here.

That is, the draining rollers 27b and 27c are in pressure contact with each other, and drain the water by passing the work therebetween to squeeze out the moisture adhering to the work. Then, the air blown from the blower nozzle 29 is strongly blown to the drained work, and the moisture is further blown off and removed. Then, the work from which the moisture has been sufficiently removed is passed between the heaters 31 by the sub-conveyor 15, where a small amount of remaining moisture is evaporated and removed. The water removed in these draining and drying steps is received by a bucket 33 below the table 3 and collected in a water tank.

Next, the operation of the wet deburring apparatus having the above configuration will be described.

The plate material work which has been subjected to the press working is supplied to the right end of the table 3, and is conveyed to the deburring wheel 5 on the table 3 by the conveyor device 11. The deburring wheel 5 reciprocates in the front-rear direction while being rotated at a high speed by the drive motor 7, and comes into contact with the conveyed workpiece to continuously perform the deburring operation. At this time, the pinch rollers 9a and 9b hold the work on both sides of the deburring wheel 5 to prevent the work from dancing during the deburring operation.

During the deburring operation, water from the water tank 35 is applied to the vicinity of the deburring operation by the pump 21 through the tube 23 and the water distribution pipes 19a and 19b.
The deburring operation is performed in a wet state, and the deburring wheel 5 is used.
The heat generated by the frictional heat caused by the contact friction between the workpiece and the workpiece can be sufficiently cooled, and the burr debris and fine dust removed from the workpiece can be taken into the water. Deburring work can be performed without deterioration.

The work on which the deburring operation has been completed is further conveyed to the left by the conveyor device 11 and passes under the brush roller 25. The fine powder is swept away, and thereafter, the remaining deburring debris and fine dust are washed away by the water sprayed from the water distribution pipe 19c, and the draining rollers 27a to 2c constituting the drying device are washed away.
7c.

In the part of the draining rollers 27a to 27c,
Draining is performed by rotating the draining rollers 27a to 27c while pressing them against the front and back of the work. Then, after being fed into the lower part of the blowing nozzle 29 after the draining rollers 27a to 27c, the water on the work is blown off by the strong wind blown from the blowing nozzle 29, and the sub-conveyor device 1
After being conveyed to the position of the heater 31 by 5, it is dried by the heat of the heater 31, and thereafter is carried out from the left end of the table 3.

On the other hand, the water supplied to the work from the water distribution pipes 19a to 19c, the water drained at the draining rollers 27a to 27c, and the water blown off by the wind from the blowing nozzle 29 are all received by the bucket 33. The water in the bucket 33 is supplied to the water tank 3 from the bottom thereof.
5, and the debris and fine dust are filtered off by the filter paper 37 and then collected in the water tank 35. Then, the water collected in the water tank 35 is supplied to the water distribution pipes 19a to 19c by the pump 21, and is reused.

As described above, in this embodiment, the deburring is performed in a wet manner, and the work on which the deburring operation has been completed is dried by removing moisture with a drying device.
First, water is drained by a drain roller, and the water on the work is blown off by the wind blown out from the blower nozzle with strong force. Further, the remaining water is dried and removed by heating with a heater, and the moisture is sufficiently dried and removed. Work that has been sent out.

The present invention is not limited to the above-described embodiment, and is not particularly limited as long as it is a processing apparatus that performs wet machining. The drying apparatus of the embodiment can be widely used.
