Description

[Detailed description of the invention] (Industrial field of application and overview of the invention) This invention removes cutting oil attached to cut products (hereinafter simply referred to as products) manufactured by cutting, and It relates to the structure of an apparatus for cleaning the product.

Normally, when cutting is performed, cutting oil is used for the purpose of preventing heat generation of the cutter and workpiece, removing chips, and the like. As a result, cutting oil will adhere to products manufactured by cutting, and cleaning of the workpiece will be required as a post-process.

The present invention aims to shorten the time required and perform high-quality cleaning by cleaning after deoiling.

(Prior art and its problems) Conventional products are washed by immersing a mesh basket containing the products in a cleaning solution and vibrating or rocking the basket. As a result, the cutting oil adhering to the product is diffused into the cleaning fluid and removed.

However, this conventional method has the disadvantage that cleaning takes a long time. This is because the amount of cutting oil to be diffused into the cleaning fluid is large.

(Problem) The present invention is designed to:
The objective is to reduce the amount of cutting oil that is removed by dispersing it with a cleaning fluid to an extremely small amount.

(Means) The means of the present invention taken to solve the above-mentioned problems are as follows.
The container has a tapered shape in which the diameter of the body increases toward the open upper end, and through holes 2, 2 for discharging the separated liquid are provided near the open upper end, and the cleaning liquid discharge port of the cleaning liquid input device 3 is connected to the container 1. A valve device that opens and closes the cleaning liquid input path from the cleaning liquid input device 3 is inserted into the cleaning liquid input path from the cleaning liquid input device 3, and in relation to a drive device that rotationally drives the container 1, the opening and closing of the valve device is performed. A control device 6 for controlling timing is provided,
This control device 6 is operated so that the valve device opens and the injection of the cleaning liquid is started after the container 1 has rotated for a certain period of time and oil removal from the cut workpieces stored therein has been completed. This is what I did.

(effect) The above technical means works as follows.

A cutting product as a product is stored in the container 1,
When the centrifugal separator is put into operation, the container 1 rotates at high speed, and the centrifugal action causes the cutting oil attached to the product to be separated from the product and pressed against the inner wall of the container 1, and due to the upward component of the pressing force. , ascends the inner wall of the container 1 and is discharged to the outside through the through holes 2, 2.

If this oil removal operation continues for a certain period of time, most of the cutting oil from the product housed in the container 1 will be removed. Thereafter, the valve device is opened by the action of the control device 6, and the cleaning liquid from the cleaning liquid injection device 3 is poured into the container 1 from the cleaning liquid discharge port.

As the container 1 rotates, this cleaning fluid flows over the surface of the products contained therein, and a small amount of cutting oil adhering to the products is diffused and eluted into the cleaning fluid. It is discharged to the outside from holes 2, 2. After this cleaning process continues for a certain period of time, the supply of the cleaning liquid is stopped and the rotation of the container 1 is also stopped, thereby completing the cleaning of the product.

(Effects) Since the present invention has the above configuration, it has the following unique effects.

Since the product is cleaned with a cleaning liquid after once deoiling, the amount of cleaning liquid used can be reduced and the product can be cleaned in a short time. Furthermore, there is no need to worry about poor cleaning.

Furthermore, since the degree of deterioration of the cleaning liquid is small, the recovered cleaning liquid can be used repeatedly.

(Example) A first example of the present invention will be described based on FIGS. 1 to 3.

In this case, a pedestal 7 provided on a lower case 10 is rotationally driven by an electric motor 5, and a container 1 is removably held on this pedestal, so that the container 1 is moved to the pedestal 7. It is rotated along with the

The upper case 9, which is removably covered with the lower case 10, is rotatably provided with a lid 8, which covers the container 1 mounted on the pedestal 7, and in the operating state, the container 1 is It is designed to rotate with the

On the other hand, the cleaning liquid input device 3 includes a cleaning liquid tank 31,
It consists of a conduit 32 leading to the central opening of the lid 8 and a solenoid valve 4 provided in this conduit, and cleaning liquid is poured into the container 1 while the solenoid valve is open.

Next, a cavity 20 is formed in the lower case 10 to collect cutting oil or cleaning fluid discharged from the through holes 2, 2, and a discharge pipe 11 is led out from this cavity 20. The downstream side of this discharge pipe 11 is
As shown in FIG. 2, the switching valve 12 is used as a branching point to branch into a first channel 13 for discharging cutting oil and a second channel 14 for discharging cleaning fluid.

The above-mentioned solenoid valve 4, electric motor 5 and switching valve 12
is controlled by a control device 6, and in this embodiment, the control device 6 has a circuit configuration that operates according to the flowchart shown in FIG.

According to this embodiment, when the product is placed in the container 1 and the start button is pressed, the
Cutting oil adhering to the product is discharged along the route of through hole 2→vacancy 20→switching valve 12→first channel 13, and during this time, most of the cutting oil on the product surface is removed.

Next, the cleaning process is automatically started, and the cleaning operation continues for a certain period of time. At this time, since the circuit of the switching valve 12 has been switched, the cleaning liquid discharged from the through hole 2 will be discharged from the second flow path 14 side. After cleaning, the solenoid valve 4 is closed, and each part returns to its initial state and stops.

As described above, in this embodiment, not only deoiling and cleaning proceed continuously, but also cutting oil and cleaning fluid can be recovered through separate routes, so there is no inconvenience that they may mix. Therefore, the collected cutting oil and cleaning fluid can be reused.

Next, a second embodiment will be described based on FIGS. 4 to 8.

In this case, a container 1 is housed in an auxiliary container 15 so as to be relatively rotatable, and as shown in FIG.
A first protruding piece 18 is provided on the outer side surface of the container 1,
Second protruding pieces 19, 19 are provided on both sides of the first protruding piece 18 at a predetermined interval on the inner surface of the side portion of the auxiliary container 15 so as to engage with this. Thereby, the container 1 and the auxiliary container 15 are connected to the second projecting piece 1.
The relative rotation will occur within a range of 9 and 19 intervals. Further, in the upper part of the auxiliary container 15, a through hole 2,
2, and second openings 17, 17 are provided at the bottom, respectively, and a through hole is provided only at one end of the relative rotation area between the container 1 and the auxiliary container 15. 2, 2 and the first opening portions 16, 16 so that these first opening portions 16, 16 coincide in the radial direction.
6 installation positions are set. Also, auxiliary container 15
A lid 8 rotatably attached to the upper case 9 is in contact with the upper end, and the driving force of the electric motor 5 is directly transmitted to the auxiliary container 15, and the lid 8 in contact with it is also connected to the auxiliary container 15. It rotates as one.

The electric motor 5 of this embodiment is a reversible motor that rotates forward and backward, and is switched between forward and reverse by a control device to be described later. When the electric motor 5 rotates forward, the first protruding piece 18 rotates one of the second protruding pieces 1
9, the container 1 and the auxiliary container 15 rotate together with the through holes 2, 2 and the first openings 16, 16 aligned as shown in FIG. When rotating in reverse, the first
The protruding piece 18 abuts the other second protruding piece 19,
As shown in FIG. 7, the through holes 2, 2 and the first opening 1
The container 1 and the auxiliary container 15 rotate together in a state where 6 and 16 are shifted.

Further, a cleaning liquid injection device is provided in the same manner as in the first embodiment, and cleaning liquid is poured into the container 1 while the electromagnetic valve 4 is open.

The lower case 10 is divided into a first cavity 21 and a second cavity 22 by a partition 25, and each has the above-described first openings 16, 16 and second openings 17, 17.
are facing each other separately, and furthermore, the first vacant room 21
and the second discharge pipe 23 and the second discharge pipe from the second empty chamber 22, respectively.
Discharge pipes 24 are led out separately.

The solenoid valve 4 and the electric motor 5 are controlled by a control device 6, and the control device 6 has a circuit configuration that operates according to the flowchart shown in FIG.

According to this embodiment, when the product is placed in the container 1 and the start button is pressed, the electric motor rotates in the forward direction for a certain period of time, so the relative positional relationship between the container 1 and the auxiliary container 15 is as shown in FIG. As a result, the cutting oil attached to the product flows through the hole 2 → the first opening 16 → the first cavity 2.
It is discharged along the route 1→first discharge pipe 23.

Next, the electric motor 5 stops for a certain period of time, then starts rotating in reverse, and moves on to a cleaning process for a certain period of time. At this time,
The relative positional relationship between the container 1 and the auxiliary container 15 is as shown in FIG. 7, and the cleaning liquid is discharged along the route of the through hole 2 → second mouth part 17 → second cavity 22 → second discharge pipe 24.

After cleaning, the solenoid valve 4 is closed and each part is stopped.

The product of this example is also deoiled as in the first example →
Washing proceeds continuously. Furthermore, in this case, the discharge paths for the cutting oil and the cleaning fluid are completely separate from the through hole 2 onward, so that the cutting oil and the cleaning fluid can be completely separated and recovered.

Furthermore, although the side wall of the auxiliary container 15 is vertical in FIG. 4, if it is tapered so as to expand downward, the cleaning liquid can be discharged from the second opening 17 more quickly. become.

In both the first embodiment and the second embodiment, the through hole 2 of the container 1
The shape of the part is smooth. If this part is formed by providing through holes 2, 2 in a rib 26 that is wound outward in a convex manner as shown in FIG. It stops moving. As a result, the lid 8 of the second embodiment becomes unnecessary, and the lid 8 of the first embodiment also becomes unnecessary by extending the side wall of the pedestal 7 to the lower part of the rib 26.
