DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a metal work piece. More specifically, for example, when cleaning a long metal rod or the like into a predetermined length and applying it to a machine tool or the like, washing and removing chips and cutting oil adhering to the metal workpiece Regarding the device.

[0002]

2. Description of the Related Art Recently, automation has been increasingly required in various industrial fields, and automatic machines such as NC machine tools, machining centers and welding robots have been introduced and are operating in, for example, a machining factory. Although these machines have completed the technology to automatically perform basic processing operations such as cutting, cutting, and welding, respectively, these machines can be used to supply materials and to further process articles processed by these machines. When processing with another machine, automation of the processing of the work piece is delayed and it is often done manually.

For example, when processing a short rod-shaped metal machine part or the like, a long metal rod material is cut into a predetermined length by an automatic band saw machine and the like, and the machined tool such as an NC lathe is formed into a desired shape. When cutting etc., if chips or cutting oil etc. at the time of cutting adhere to the work piece, it will cause defects during cutting etc. Needs to be cleaned and removed. As a technique for cleaning such a work piece, for example, a cleaning device has been actively developed for high value-added parts such as semiconductors and printed circuit boards. With respect to the processed product, there has been little motivation for development so far, and the cleaning device suitable for such a metal processed product has not been developed yet.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above situation, and a cleaning device suitable for a metal work piece such as a machine part, particularly a metal work piece as described above, can be easily and reliably provided. Moreover, it is an object of the present invention to provide a cleaning device capable of automatically cleaning.

[0005]

In order to achieve the above object, a cleaning device for a metal workpiece according to the present invention has the following configuration.

That is, a mesh belt conveyor is arranged in a substantially box-shaped cleaning tank containing a cleaning liquid, and an air discharge pipe is arranged below the belt conveyor. It is characterized in that air is sequentially discharged from the air discharge pipe to wash the product while being conveyed by the conveyor.

[0007]

According to the cleaning apparatus of the present invention configured as described above, metal workpieces such as machine parts are sequentially charged onto the mesh belt conveyor in the cleaning tank, and air is discharged below the metal conveyor. By discharging air from the pipe, it is possible to automatically and easily and reliably clean the metal work piece by the stirring action and aeration action of the cleaning liquid by the air discharged from the air discharge pipe. Become.

BEST MODE FOR CARRYING OUT THE INVENTION A cleaning apparatus according to the present invention will be specifically described below with reference to the embodiments shown in the drawings. FIG. 1 is a plan view showing an embodiment of the apparatus for cleaning a metal workpiece according to the present invention, FIG. 2 is a vertical sectional front view thereof, and FIG. 3 is a vertical sectional side view thereof.

In the figure, reference numeral 1 is a substantially box-shaped cleaning tank, and the cleaning tank 1 has an upper surface opened and a caster 2 for movement is provided on the lower surface of the bottom. A cleaning liquid L is accommodated in the cleaning tank 1, and a reticulated belt conveyor 3 is accommodated and arranged so that one end side is immersed in the cleaning liquid L.

The belt conveyor 3 is formed in an endless shape, and chains 31 are integrally provided on both sides in the width direction thereof. Each chain 31 is wound around a plurality of sprockets 4, and each of the sprockets 4
Is rotatably attached to and supported by a downwardly U-shaped frame 6 and a bearing member 7, which are attached to the bottom of the cleaning tank 1 via a pedestal 5.

On the upper part of the frame body 6, a belt conveyor 3
Drive motor 8 is arranged, and the output shaft 8 of the motor 8
drive sprocket 9 on a to input shaft 10 of conveyor 3
By transmitting power to the upper driven sprocket 11 via the chain 12, the belt conveyor 3 is rotated in a direction indicated by an arrow in the drawing at a predetermined speed. A torque limiter 13 is interposed between the driven sprocket 11 and the conveyor input shaft 10 so that when the belt conveyor 3 is overloaded, the driven sprocket 11 is rotated.
Is rotated with respect to the conveyor input shaft 10.

An air discharge pipe 14 is arranged below the belt conveyor 3 and in the lower part of the endless belt conveyor 3 in the figure. Compressed air is supplied to the air discharge pipe 13 from a compressor (not shown) through a supply hose 15 and a solenoid valve 16, and the air discharge pipe 14 is provided at a position located inside the belt conveyor. A large number of small holes for releasing air are formed, but they are omitted in the drawing.

The cleaning liquid may be appropriately selected according to the degree of dirt on the work to be cleaned and the type of oil adhering to the work. For example, a metal rod cut by the automatic band saw machine as described above. In the case of washing, the low-foaming alkali washing liquid or the like may be used. Further, the temperature of the cleaning liquid can be appropriately adjusted by the heater 17 arranged in the cleaning tank 1. Further, the moving speed of the belt conveyor 3 and the ejection amount of air discharged from the air discharge pipe 13 can be adjusted appropriately.

A work piece such as a metal rod material (hereinafter referred to as a work), which is sequentially cut into a predetermined length by the automatic band saw machine as described above, by the cleaning apparatus having the above-described structure.
When cleaning W, the cleaning tank 1 is moved below the discharge chute S or the like of an automatic band saw (not shown) so that the works W sequentially discharged from the chute S fall onto the belt conveyor 3. To

In this state, the belt conveyor 3 is rotationally driven at a predetermined speed, the electromagnetic valve 16 is opened and air bubbles are discharged from the air discharge pipe 14, and the work dropped on the conveyor 3 is moved together with the conveyor. The cleaning liquid is moved in the cleaning liquid in the cleaning tank 1 and is sequentially cleaned by the stirring action and the aeration action of the cleaning liquid by the air discharged from the air discharge pipe 14. The washed work continues to move on the conveyor 3 and drops downward from the end opposite to the shooter S, and at the drop position, a recovery container C with casters as shown in the figure.
By arranging etc., it is possible to collect automatically in sequence.

As described above, according to the cleaning apparatus of the present invention,
Since the work made of the metal workpiece is moved on the reticulated belt conveyor 3 immersed in the cleaning liquid to eject the foamy air for cleaning, the cleaning can be efficiently performed and the above-mentioned automatic It is possible to automate a series of operations including a machining operation by a machine tool such as a band saw machine and the like until the workpiece machined by the machine is washed and collected in a container. In addition, the above cleaning device,
A chip collecting machine for cleaning the work and discharging and removing the chips and the like accumulated at the bottom of the cleaning tank 1 at a proper time is provided, but it is omitted in the drawing.

[0017]

As described above, in the cleaning apparatus according to the present invention, the metal workpiece to be cleaned is moved by moving it on the conveyer immersed in the cleaning liquid while injecting air to clean the metal workpiece. The work piece can be efficiently and continuously washed. Further, since the cleaning efficiency is good, there is an effect that a sufficient cleaning power can be secured even if the device is made compact and compact, and it can be easily automated.
