[0002]

2. Description of the Related Art Recently, many unmanned factories have been constructed, and incidentally, the development of NC machine tools, multi-spindle lathes, machines dedicated to automatic machining, etc. has been active. However, none of these machines considers the cleaning of the machined workpiece.

Generally, a work transferred from a machine is
Cutting chips, cutting chips, etc. are attached, and cutting oil remains in the processed holes and thread grooves. These must be removed before the next process step.

As a conventional typical work cleaning device,
There is one in FIG.

As shown in FIG. 9, this work cleaning device 130 is generally equipped with a cleaning oil tank 132 for storing cleaning oil, and a part of the cleaning oil tank is immersed in the cleaning oil and part of the cleaning oil is removed from the cleaning oil. It has a basket member 134 in which a large number of small holes having a U-shaped cross section, which are obliquely arranged so as to emerge, and a motor (not shown) that swings the basket member to the left and right. As shown in FIG. 10, the work cleaning device 130 is characterized in that irregularities are formed on the bottom surface of the basket member in a staggered manner, and when the basket member is swung left and right, the work passes through the groove and the arrow mark. The point is that it can be moved only in the direction of 135. In the figure, thick lines represent mountain fold lines and alternate long and short dash lines represent valley fold lines. Therefore, the groove portion through which the work passes is formed along this valley fold line.

[0006]

The above-described work cleaning device 130 can supply an appropriate amount of works from the hopper 136, for example, about 200 works in the C-shaped body for the grease nipple shown in FIG. Since it uses a manual supply method, it has the drawback that it cannot be used in an unmanned factory. Further, if the basket member 134 is swung quickly, there is a drawback that the washing oil is stirred up and the precipitated chips and cutting dust are blown up and the work is damaged. Therefore, the oscillation cycle is naturally limited, and the number of cleaning oil drains of the work per unit time is small.

In this work cleaning device 130, about 200 C-shaped main body for grease nipple shown in FIG.
It took about 15 minutes to wash the individual pieces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The article cleaning apparatus of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic layout view of a fully automatic work processing system including an embodiment of a work cleaning apparatus according to the present invention.

In the figure, a fully automatic work processing system 1
Reference numeral 0 has a machine tool 12 for machining a workpiece, a workpiece cleaning device 20, and a manipulator 14 for transporting the machined workpiece to the workpiece cleaning device 20. Of course, the arrangement of the components shown in the figure is an example, and there are various patterns depending on the machine tool, the manufacturer of the manipulator, and the type.

The work cleaning device 20 is for cleaning the work on which cutting chips, cutting chips and the like are adhered continuously with washing oil, and then draining the washing oil adhering to the work. As shown in FIG. 2, the work cleaning device 20 includes a cleaning oil tank 22, a cylindrical basket 24, a drive motor 26 for continuously rotating the basket, and a container 24 adjacent to the basket 24. And a hopper 28 that is arranged as a unit.

The washing oil tank 22 stores the washing oil for washing off the chips, cutting wastes and the like adhering to the work.
It is also possible to install a pipe for filtering and collecting the cutting chips and cutting chips that have settled on the bottom surface.

The basket 24 is obliquely arranged so that a part thereof is immersed in the washing oil and a part thereof comes out of the washing oil, and is rotated by a drive motor 26. By making it possible to change the angle of the basket 24 with respect to the horizontal direction or the rotation speed of the basket 24, it is possible to change the cleaning efficiency of chips and cutting dust and the draining efficiency of washing oil.

The basket 24 has an outer cylinder 24a having a large number of small holes and a work transfer path 24b spirally formed along the inner peripheral surface thereof. As the outer cylinder 24a, various materials such as metal and plastic can be adopted,
There are various types such as a plate-shaped member in which small holes of various shapes are formed by press working, an expanded or ordinary wire mesh, and a molded product with small holes.

In the illustrated embodiment, the outer cylinder 24a has a cylindrical shape, but it may have another shape, for example, a regular polygonal cylinder.

The work conveying path 24b can be formed by various methods. In the example shown in FIG. 3, the spiral blade 24c is fixed along the inner peripheral surface of the cylindrical outer cylinder 24a. Is provided by. Further, in the example shown in FIG. 4, it is provided by the spiral protrusion 24d formed by pressing the cylindrical outer cylinder 24a. In addition, in FIG. 4, the outer cylinder 24a is shown for the sake of clarity.
Some of the small holes formed in the above were omitted. Further, the outer cylinder 24
When a is a plastic molded product, it is possible to simultaneously mold the small protrusions and the spiral protrusions 24d.

The drive motor 26 can continuously rotate the basket 24 in the forward and reverse directions by various conventionally known mechanisms.

The hopper 28 is located at a position adjacent to the upper end surface of the basket cylinder 24, into which the workpiece machined by the machine tool 12 is inserted, and from the upper end surface of the basket cylinder 24 into the basket cylinder 24 to wash oil. It has an extension portion 28b that extends to the vicinity of the other end surface of the basket 24 dipped therein and drops the work into the basket inside 24 at that position. In the illustrated embodiment,
Since the work cleaning device 20 is continuously operated by continuously rotating the drive motor 26 in the forward direction, the extension portion 28b of the hopper 28 enters the inside of the basket cylinder 24 from the upper end surface of the basket cylinder 24 and is immersed in the cleaning oil. It extends near the other end surface of the basket 24. On the other hand, when the drive motor 26 is rotated in the forward and reverse directions, the work cleaning device 20 is in batch operation, but the length of the extension portion 28b may be short. Alternatively, it is also possible to enter the inside of the basket cylinder 24 from the other end surface of the basket cylinder 24 and drop the work into the basket cylinder inside 24 at that position.

Next, the performance of the workpiece cleaning device 20 that has been prototyped will be described based on the schematic side view shown in FIG.

FIG. 5 is an exploded perspective view of the prototype, and FIGS. 6 (a) to 6 (c) are a plan view, a front view and a right side view of essential parts of the prototype, and FIGS. FIG. 8B is a front view and a left side view of an upper half of the basket used in the prototype, and FIGS. 8A to 8C are plan views of a frame portion supporting the basket. It is a front view and a right side view.

In the prototype of the work cleaning device 20, a frame 30 supporting the basket 24 is swingably attached to a frame 32 installed so as to surround the washing oil tank 22 with a shaft member 34 as a fulcrum. .

The gear 2 is provided on the outer peripheral surface of the basket 24 on the open end side.
4e is provided so as to mesh with the gears 30a and 30a of the frame 30. One gear 30a of the frame 30 is drivingly connected to the drive motor 26 as shown.

The side of the basket 24 opposite to the open end is closed by a disc-shaped lid 24f as best shown in FIG. The basket 24 has a pair of idle rollers 30b, 30b on the side opposite to the open end of the basket 24.
And the center of the lid 24f is supported by the thrust bearing 30c.

In the prototype shown in FIG. 5, the outer cylinder 24b of the basket 24 is used.
Is a plurality of ridges 2 parallel to the axial direction along its inner peripheral surface.
4 g are formed. When the C-shaped main body for the grease nipple shown in FIG. 11 is washed, the presence of the ridge portion 24g ensures the rolling of the work, thus improving the washing and draining efficiency of the work.

The frame 30 further has a discharge chute 30d at a position adjacent to the open end of the basket 24 when the basket 24 is attached to the frame 30. The discharge chute 30d receives the work that has been washed and drained from the basket 24 and guides it to a predetermined position.

Using this prototype, the C-shaped main body for the grease nipple shown in FIG. 11 was washed and drained.

The angle α of the basket 24 with respect to the horizontal can be changed by moving the angle side of the frame 30 up and down. When the angle is about 30 degrees, the work can be efficiently washed and drained. As a result of various experiments, basket 2
It has been found that the angle α with respect to the horizontal of 4 is preferably in the range of 20 degrees to 40 degrees. If the angle α is too small, it becomes necessary to increase the length of the basket 24 and it takes time to clean the work. On the other hand, if the angle α is too large, the work slips on the inner peripheral surface of the basket 24. The result is that it does not come out of the basket 24.

The rotation speed of the basket 24 can be changed by changing the rotation speed of the drive motor 26.
When the rotation speed is increased, the cleaning speed is increased, but a phenomenon occurs in which the work sticks to the inner peripheral surface of the basket 24 due to centrifugal force and does not roll well, and when the rotation speed is low, the cleaning speed is reduced. The rotation speed of the basket 24 seems to be 5 to 10 rotations per minute, preferably about 7 rotations per minute.

The basket 24 was rotated at an angle of 30 degrees with respect to the horizontal, and the basket 24 was rotated 7 times per minute. When 5000 C-shaped main bodies for grease nipples were put into the basket 24 and washed, all the workpieces were discharged from the open end of the basket 24 in about 10 minutes.

The cleanliness of the work was good, and the work surface was not scratched. In addition, since it is a rotational movement,
Also, no large noise was generated unlike the conventional work cleaning device shown in FIG.

As described above, the conventional work cleaning apparatus 1
In 30, the same size equipment can handle about 200 workpieces
The work cleaning device 20 according to the present invention is cleaned in 5 minutes.
The cleaning efficiency is about 38 times.

The work cleaning device 20 according to the present invention.
Rotates the basket 24 in the reverse direction to load the work into the basket 2.
4 can be held on the lower end side. Therefore, even a work having a structure in which contaminants are hard to be removed can be cleaned effectively by adjusting the reverse rotation time.
