Referring to FIGS. 2, 3 and 4, the cleaning device 10
The cleaning liquid L is filled in the cleaning liquid circulation line including the cylindrical container 21 and the cleaning liquid tank 51, and the driving unit 71 of the cleaning device 10, the pump 52 of the cleaning liquid L, the motor 82 of the cleaning liquid separating device, etc. are energized to operate. It is assumed that the sequence control device and the time control device in each place are in control by the control panel.

The valve component V shown in FIG. 1 which has been cut by the milling machine 1 is a fine chip P generated by the cutting process.
Along with this, cutting oil is attached to the chute 2 and the cleaning device 1
No. 0 is supplied from the central portion of the cylindrical container 21 and the opening 8 of the upper lid 7.

Referring to FIGS. 5 and 6, the supplied valve component V drops to the bottom surface of the inner cylindrical container 11, but since the inner cylindrical container 11 and the cylindrical container 21 are torsionally oscillated integrally, The component V is moved to the peripheral portion, and the track 14 is in a recumbent posture in which the longitudinal portion is in contact with the side wall 13 and the direction is indefinite.
It is transferred counterclockwise on the top. Since the cleaning fluid is transferred in the cleaning liquid L while being vibrated, the cleaning action is performed, and the adhering cutting oil and the fine chips P start to be washed off, but the fine chips P are dispersed and suspended in the cleaning liquid L. Like If there is a large chip P ', it is separated from the valve part V and begins to be transported on the track 14 like the valve part V.

The valve component V ascends along the track 14 and falls outward from the notch 16 formed in the side wall 13 up to the uppermost portion, but below the notch 16 the side wall 13 is formed.
Onto the resonance track 17 attached to the outer periphery of the cylindrical container 21 and is transferred about half a circle on the resonance track 17 to fall on the bottom surface of the cylindrical container 21. Since the resonance track 17 resonates with the torsional vibration, the valve component V is also subjected to the resonance vibration while being transferred on the resonance track 17 to enhance the cleaning effect.

A valve component V that has fallen to the bottom of the cylindrical container 21.
Also in this case, it is moved to the peripheral portion due to the torsional vibration, and the track 24 is transported counterclockwise in a recumbent posture in which the longitudinal portion is in contact with the side wall 23. Since air is bubbled from the blowing space 28 provided below the track 24 from the starting point of the track 24 through the pores 29 formed in the track 24, the valve component V The cleaning effect is enhanced.

The valve component V is transferred on the track 24, lifted up and released from the cleaning liquid L, and then reaches the posture control section 31 via the horizontal track 24F. Up to this point, the valve component V that has been transferred in a recumbent posture with an indefinite orientation is placed on the groove 37 formed by the angle member 32 and the width adjusting member 34, as shown in FIGS. 8, 9, and 10. At, the posture is adjusted. That is, since the width of the groove 37 is smaller than the maximum diameter of the tapered portion N of the valve component V, the valve component V transferred with the tapered portion N at the head and the valve component V transferred with the notch M at the beginning. Each of the Vs is adjusted to a posture suitable for the jet cleaning in which the tapered portion N is fitted in the groove 37 , and is transferred to the jet cleaning section 41 on the downstream side.

In the jet cleaning section 41 located on the same groove 37 as the attitude control section 31, as shown in FIGS. 8, 9 and 11, the preceding valve component V is pressed by the rubber pad 44 at the rod tip of the air cylinder 42. Since the transfer has been stopped, a row of valve parts V is formed here. On the other hand, at the downstream end of the groove 37 , as shown in FIGS.
As shown in FIG. 12, the two stopper pins 47 are pushed out by the air cylinder 45, and the valve component V is stopped at the injection cleaning position immediately below the injection nozzle 55 where the cleaning liquid L is constantly injected, for a predetermined time. In the meantime, the valve component V is spray-washed mainly with the stepped hole with the clean cleaning liquid L, and the cleaning liquid L containing the fine chips P and adhering is washed away.

When the jet cleaning for a predetermined time is completed, the stopper pin 47 is pulled back, the transfer of the valve component V is resumed, and the valve component V is moved to the next drainage track 61, but the subsequent valve component V is still pressed by the rubber pad 44. is there. After the stopper pin 47 has been pushed out in preparation for the next injection cleaning, the pressing of the rubber pad 44 is released, and the succeeding valve component V advances by one downstream, and moves to the most advanced injection cleaning position. At the same time as the injection cleaning is started, the rubber pad 44 is pushed out by the following two valve parts V and presses them. By repeating such a cycle, the injection cleaning of the valve component V is performed for a predetermined time, and the cleaning liquid L used for the injection cleaning flows down into the cylindrical container 21 through the groove 33.

While the valve component V for which the jet cleaning has been completed is transferred by the torsional vibration on the drainage drainage truck 61, the cleaning liquid L attached at the jet cleaning unit 41 flows down and is shaken off to be drained. The drained cleaning liquid L flows down into the cylindrical container 21 through the gap 64 of the baby cage.

The valve component V is further transferred from the deliquoring truck 61 to the deriving truck 66 and led out from the cleaning device 10 to the outside. During this period, referring to FIG. 7, large chips P ′ that are not dispersed and suspended in the cleaning liquid L and are transferred in the same manner as the valve component V are provided at the connection points between the drainage track 61 and the discharge track 66. A relatively large connecting gap 6
At 5 there is a fall onto the lower truck 24 and the transfer to the outlet truck 66 is blocked. Large chips P'fallen
Are flushed and discharged by the overflowing cleaning liquid L. Of course, even by then, the large chips P ′ are separated by the track 14 of the inner cylindrical container 11 and the track 24 of the cylindrical container 21, and the track 14, like the valve component V,
When the liquid 24 is transferred, it is discharged together with the cleaning liquid L from the overflow hole 26 reaching the posture control unit 31 and the jet cleaning unit 41.

The washing liquid L that overflows has dispersed and suspended fine chips P that have been washed, but a chip filter 58 that has passed from the overflow receiver 56 to the return liquid tube 57.
The fine chips P are sieved in the
The cleaning liquid L that has passed through does not contain fine chips P. Even when a large chip P ′ flows along with the overflowing cleaning liquid L, it is similarly sifted by the chip filter 58. The swarf filter 58 is replaced with a new or remanufactured product when a predetermined amount of swarf P, P ′ is accumulated.

Although the cleaning liquid L returns to the cleaning liquid tank 51 through the chip filter 58, the cleaning liquid tank 51 is provided with an oil component of the surface layer formed by separating the cutting oil from the cleaning liquid L in the stationary state in the cleaning liquid tank 51. Oil Sukima 10
5 is adsorbed on the surface of the rotating lipophilic disc 107, lifted to the upper part and removed by the scraping blade 108 to prevent the oil content cleaning ability of the cleaning liquid L from decreasing.

The valve component V is supplied from the lead-out track 66 through the chute 67 to the inlet 95 of the cleaning liquid separating device 80. A shutter 96 operated by an air cylinder 97 is provided at the inlet 95, and the shutter 96 is opened during the low speed rotation of the screw shaft 84 which repeats the high speed rotation and the low speed rotation in the main body 81 to open the valve component V. Is supplied to the space of the spiral screw blade 83.

When the screw shaft 84 rotates at a high speed, the supplied valve component V receives a centrifugal force, and is rotated in contact with the inner surface of the punching plate 85 having a long cylindrical shape rotated by the screw shaft 84. The cleaning liquid L is separated, passes through the holes of the punching plate 85, jumps out, and adheres to the inner wall of the main body 81.
That is, the valve component V is transferred during high-speed rotation, but the main function is to centrifuge the cleaning liquid L. During low speed rotation, the valve parts V gather at the bottom of the punching plate 85 and are conveyed downstream by the screw blades 83.
The product is dropped from the discharge port 86 into the product receiving box 99 and accommodated. On the other hand, the cleaning liquid L attached to the inner wall of the main body 81 naturally flows down and flows downward along the bottom surface of the flow path 87 at the bottom of the main body 81,
It is recovered in the recovery cleaning liquid tank 89 via the discharge tube 88. Liquid level of collected cleaning liquid tank 89 and cleaning liquid tank 51
The liquid level of the same becomes the same height by the communication pipe 89.

As described above, according to the present embodiment, the machined part V is conveyed while repeating the small jump motion due to vibration on the track 14 of the inner cylindrical container 11, so that the periodic impact force is applied to the cleaning liquid L. By receiving it inside, fine chips adhering to the wall of the inner hole h can be efficiently dropped, and further, the inner cylindrical container 11
A large impact force is exerted when it falls to the bottom of the external cylindrical container 21 from the above, and the adhering chips and foreign substances can be efficiently dropped. Even on the track 24 of the container 21, fine impactive chips and foreign substances still adhered to the wall of the inner hole h as well as the outer surface by being subjected to the periodic impact force in the cleaning liquid several times in the liquid. Can be dropped. Furthermore, the uppermost portion of the truck 24 is in an upright position with the stepped hole h in a vertical state, and the cleaning liquid is locked from the upper portion for a predetermined period of time to flow out. It can also be removed here and fed to the next step. Further, since the chips of the brass component V of this embodiment are very small, the fact that they are transferred from the liquid surface by vibration on the truck and cannot be discharged into the atmosphere is discharged together with the cleaning liquid by the overflow method. Therefore, the cleaning liquid in the cylindrical container 21 is not contaminated in a short time, and since the circulation system is adopted in the present embodiment, the cleaning can be always performed in a clean state. Can be significant.

Although the apparatus for processing a machined product according to the present invention has been described above with reference to the embodiments, the present invention is not limited to this, and various modifications can be made based on the technical idea of the present invention. .

For example, in this embodiment, the jet cleaning unit 4
In No. 1, the cutout portions M of the two valve components V are pressed by the two rubber pads 44 to stop the transfer. However, as shown in FIG. 13 corresponding to FIG. 8, instead of the rubber pads 44,
The transfer of the valve component V may be stopped by inserting the plate 144 between the valve component V in the jet cleaning position and the valve component V subsequent thereto. Since the plate 144 is replaceably attached to the attachment portion 143 at the rod tip of the air cylinder 42, adjustment is easy when cleaning valve components V ′ having different diameter sizes.

Although an alkaline aqueous cleaning liquid is used as the cleaning liquid L in this embodiment, an oily cleaning liquid L ', such as machine oil or a chlorine-based organic solvent, may be used instead. In that case, the cutting oil dissolves in the cleaning liquid L ′ and is not separated, so that the oil skimmer 105 in the cleaning liquid tank 51 becomes unnecessary.

In this embodiment, the valve component V having a complicated shape is to be cleaned, but it is of course possible to clean a machined product having a simple shape such as a round bar or a square plate. The attitude control unit 31 may be omitted.

In the present embodiment, the brass valve component V which produces fine chips P is the object of cleaning, but it is a machined product of iron material which does not produce fine chips P, for example, thread cutting with a tapping machine. Nuts and the like that have been cleaned can also be the object of cleaning.

Further, in the present embodiment, the cleaning liquid separation device 80 is connected to the cleaning device 10 to perform continuous processing. However, if continuous centrifugation is possible, a cleaning liquid separation device other than the cleaning liquid separation device 80 used in this embodiment is used. The washing liquid L may be centrifuged separately from the washing treatment by using a batch type centrifuge.

Further, in this embodiment, as the cleaning device 10, the inner cylindrical container 11 is provided inside the cylindrical container 21 to form a double cylindrical container, and the transfer distance of the valve component V in the cleaning liquid L is increased to improve the cleaning efficiency. However, the inner cylindrical container 11 may be omitted when a machined product that is easily cleaned is to be cleaned.

[0057]

As described above, according to the apparatus for processing a machined product of the present invention, a machined product that produces fine chips, for example, a brass machined product, is washed with an aqueous cleaning solution, and the fine chips are the cleaning solution. Even if it is dispersed and suspended in the machine, position the machined product in a position suitable for cleaning at a position higher than the level of the cleaning liquid, and then spray clean with a clean cleaning liquid that has been screened for chips and removed oil. Therefore, it is possible to efficiently clean and remove chips and adhering substances. Furthermore, when an aqueous cleaning liquid is used, there is no risk of ignition, and the environmental pollution problem at the time of discarding the cleaning liquid is much smaller than when an oily cleaning liquid is used.
