Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for removing chips, water, etc. remaining in a workpiece after cleaning.

(Prior art) For example, when machining an engine case for a motorcycle, a large amount of chips and cutting oil adhere to the surface and inside of the engine case. Send it in, wash it with water here,
Adhering chips and the like are removed by steam blowing or air blowing.

However, after cleaning in this way, water and chips remain in the deep holes on the top surface of the workpiece without being removed. In addition to this, additional work was required to remove chips, etc. remaining inside.

(Purpose) This invention was made in view of the above circumstances,
The aim is to provide a new device that can automatically remove residue from a workpiece after cleaning.

(Means for Achieving the Object) In other words, in order to achieve the object, the present invention provides an inverting table which is supported so as to be capable of reversing, and whose free end is normally faced diagonally upward to face the discharge end of the workpiece cleaning device. An endless belt for transporting the workpiece and a clamping member for clamping the workpiece on the endless belt are provided, and a rotatable rotatable belt is provided below the reversing position of the reversing table with a large number of nozzles ejecting gas toward the workpiece. The device is equipped with an air blow device to remove residue from workpieces after cleaning.

(Example) The details of the present invention will be explained below based on the illustrated example.

The drawing shows one embodiment of the present invention, and this device receives a workpiece w discharged from a washing machine 40, such as an engine case for a motorcycle, and inverts it onto a machine base 10. It is composed of a freely mounted reversing table 20 and an air blowing device 30 that blows air onto the work w on the inverted reversing table 20 from below.

The reversing table 20 described above is rotatably attached to bearings 11, 11 provided at the front and rear of the machine frame 10 via a shaft 22 fixed to both ends of one side of the machine frame 21, and is normally attached to the machine frame 21. The engaging part 24 provided on the other side is engaged with the engaging part 42 provided on the machine base 41 of the washing machine 40 located above the reversing table 20, and the workpiece w is held in an upwardly inclined state. When the workpiece w is discharged, the workpiece w is held and rotated in reverse by being driven by the motor 12 on the machine base 10 which acts on the sprocket 23 at the end of the shaft 22. By the way, this machine frame 21 is stretched with an endless band 26 in which stainless steel rods and synthetic resin rods are alternately arranged and bonded to sprockets 25, 25 that are pivotally supported at both ends of the frame, and one sprocket 25 acts on the shaft. The workpiece w is driven by a drive motor 27 to transport the workpiece w that has been subjected to the air blowing process to the next process. A clamp arm 28 clamps the work w discharged onto the endless belt 26, and the arm 28 is configured to be operated by an air cylinder 29.

On the other hand, the above-mentioned air blow device 30 is pivoted on the machine stand 10 so as to be horizontally rotated by a motor 31 below the inversion position of the inversion table 20, and blows out air from a large number of air pipes 32 arranged on the upper surface of the machine stand 10. It is configured to spray onto the surface of the workpiece W.

In the apparatus configured as described above, when the work w that has just finished the cleaning process is discharged from the washer 40, the engaging part 24 is engaged with the locking part 42 of the machine stand 41 of the washer 40, and the work w is moved upward. The endless belt 26 on the machine frame 21 held in an inclined state holds the work w in a fixed position by a stopper and then clamps it by an arm 28 driven by a cylinder 29.

Next, in this state, the drive motor 12 is activated and the machine frame 21 driven by it is reversed, so that the workpiece w held on the endless belt 26 is placed directly above the air blowing device 30 with its upper surface facing down. As the air blow device 30 rotates, air is blown out from a large number of air pipes 32 disposed on the upper surface of the workpiece, thereby reliably removing chips and water remaining in deep holes on the upper surface of the workpiece.

When the air blow process is completed in this way, the drive motor 12 is reversely rotated, and the machine frame 21 is returned to its original position via the sprocket 23. Then, when the arm 28 unclamps the workpiece w by the cylinder 29, the motor 27
6 is driven to send the work w placed thereon to the next process.

(Effects) As described above, according to the present invention, the workpiece that has been cleaned can be inverted from below using the reversing table that can be reversed and the air blowing device that can be rotated below the table. Since air blow treatment is used, chips, water, etc. remaining on the top surface of the workpiece can be reliably removed by air blowing action and gravity action, and at the same time, air blowing of the cleaned workpiece is carried out using a conveyor belt installed on the reversing table. Processing and subsequent transport work to the next process etc. can be performed automatically without requiring human labor, thereby reducing the cost required for this type of processing.
