7 is opened. The arm 61 is always evacuated to the position indicated by the imaginary line in FIG. 6 to avoid interference with the pin 62 during two rotations of the processing tank.

Next, positioning for stopping the processing tank 2 after the oil separation treatment at a position where the discharge ports 6 and 7 for the chips and the foreign substances are aligned with the hoppers 45 and 46 for discharging the chips and the foreign substances, respectively. The mechanism will be described with reference to FIGS. The positioning mechanism is disposed on the lower surface of the processing tank 2 near the outer periphery, and has a stopper bracket 65 fixed on the upper plate 1 a of the gantry 1, and one end of the stopper bracket 65 is rotatable in the vertical direction by a pin 66. And a stopper cylinder 68 for vertically moving the stopper arm 67.

Thus, the stopper arm 67 is mounted on the processing tank 2.
A projection 69 provided on the lower surface of the processing tank 2 has a step-shaped stopper portion 67a that can abut, and when the processing tank 2 is rotated, the processing is performed by rotating downwardly by a stopper cylinder 68 as shown by an imaginary line in FIG. Although the passage of the protrusion 69 of the tank 2 is allowed,
Is stopped, it is displaced to the horizontal position indicated by the solid line in the figure, and the protrusion 69 of the processing tank 2 comes into contact with the stopper portion 67a for positioning.

The stopper arm 67 is provided with a stopper pin 70 having an upper end formed on a tapered surface as a stopper for reversing the processing tank 2. The stopper pin 70 is set at a position opposing the stopper portion 67a of the stopper arm 67 via a mounting hole 67b so as to be freely protruded and retracted. When the protrusion 69 is pressed against the tapered surface, it is immersed.

However, in order to prevent noise during chip crushing, the entire chip processing apparatus is surrounded by a soundproof wall 75. In this embodiment, as shown in FIG. 11, the soundproof wall 75 is made of acrylic fiber for the intermediate layer 75a,
It is formed in a three-layer structure in which b is a punched metal and the outer wall 75c is an iron plate. An openable and closable cover plate 76 is provided at an upper opening of the soundproof wall 75. The lid plate 76 has a double structure including an outer lid 77 and an inner lid 78,
The outer cover 77 is rotatably attached to the soundproof wall 76 via a hinge 79 to close the upper opening of the soundproof wall 75, and the inner cover 78
Closes the chip inlet 3 of the treatment layer 2.

The inner surface of the inner lid 78 has the hammer 3
1, an appropriate number of dividers 80 are vertically provided for loosening the chips in the processing tank 2 during the crushing processing of the chips by 1.
As shown in FIG. 10, the divider 80 is rotatably suspended via a pin 82 on a bracket 81 fixed to the inner surface of the inner lid 78, and is allowed to freely tilt in the rotation direction of the processing layer 2. In the reverse direction, that is, in the rotation direction of the rotating body 30, the tilting is prevented by a locking portion 81a formed on the bracket 81, and the suspended state is maintained.

FIG. 12 is an explanatory diagram of discharge control of contaminant foreign substances during chip processing. As shown in the drawing, the foreign matter discharge control device picks up a sound with a microphone and outputs a sound at a level determined to be a foreign matter.
The control is performed such that the operation of opening and closing 1 for a certain period of time is repeated several times until foreign matter is discharged.

That is, the condenser microphone 85 picks up sound and converts it into an electric signal. The electric signal amplified by the amplifier 86 undergoes noise removal processing by the filter 87. The level adjuster 88 performs an adjustment process for comparing the comparison signal with the reference signal.
To compare the comparison signal with the reference signal. Then, as a result of the comparison, when it is determined that the sound is at a level due to foreign matter mixing,
The relay 90 is driven, and a valve for opening and closing the door 51 of the foreign matter discharge port 7 is operated. The condenser microphone 85 is, for example, an outer cylinder 1 fixed to the gantry 1.
0 or the oil pan 42.

The chip processing apparatus of the present embodiment is configured as described above, and the operation and effect thereof will be described below. A predetermined amount of chips to be processed is put into the processing tank 2, and the operation is started with the cover plate 76 closed. At this time, the doors 50 and 51 of the swarf discharge port 6 and the foreign substance discharge port 7 of the processing tank 2 are both closed, and the stopper arm 67 of the positioning mechanism is in the retracted position.

In this state, the oil-separated brake motor 13 is driven via the inverter. Thus, the first drive shaft 11 is driven via the belt 17, and the processing tank 2 is rotated in the direction of the arrow (clockwise) shown in FIG. At this time, the electromagnetic clutch 27 is in the connected state, so that the second drive shaft 20 rotates integrally with the first drive shaft 11. That is, the rotating body 30 rotates integrally with the processing tank 2, and at this time, the motor 22 for crushing chips rotates together.

The cutting oil and the like adhering to the chips are separated from the chips by the centrifugal force generated by the rotation of the processing tank 2 and discharged out of the tank through the small holes 4 of the processing tank 2. Collected by the pan 42. And gutter part 4
The oil collected in 3 is discharged outside the machine through a discharge pipe (not shown). At this time, even if the divider 80 abuts against the chips, the divider 80 escapes in the moving direction of the chips, that is, in the rotation direction of the processing tank 2, so that the rotation of the chips is not hindered, and an unnecessary load is applied to the motor 13 for separation. Avoid that.

When the oil separating operation by the rotation of the processing tank 2 is performed for a predetermined time, the separating motor 13 is connected via an inverter.
When the projection 69 on the lower surface of the processing tank 2 is located at a specific position after deceleration to a predetermined speed, the stopper cylinder 68 is operated to raise the stopper arm 67 to the horizontal level. Then, the advancing projection 69 pushes the tapered surface at the upper end of the stopper pin 70, pushes it down, passes through it, and abuts the stepped stopper 67a (see the imaginary line in FIG. 8). The stopper pin 70 protrudes after passing through the projection 69 to prevent a displacement of the processing tank 2 due to a recoil.

Thus, the processing tank 2 has its chip discharge port 6 and foreign substance discharge port 7 positioned and fixed at positions corresponding to the discharge hoppers 45 and 46, respectively.
Is stopped and the brake is operated. Subsequently, the door 50 for the chip discharge port 6 is opened. That is, the arm 61 is rotated via the rack 58 and the pinion 59 by the operation of the hydraulic cylinder 57, and the door 50 is horizontally rotated by contacting and pushing the pin 62 on the lower surface of the mounting portion 50a of the door 50. Then, the door portion 50a is moved along the outer peripheral surface of the processing tank 2 to open the chip discharge port 6.

Subsequently, the electromagnetic clutch 27 is disengaged and the motor 22 for crushing chips is driven. Therefore,
The second drive shaft 20 is driven via the belt 26, and the rotating body 30 is rotated in the direction of the arrow (counterclockwise) shown in FIG. At this time, the hammer 31 installed on the rotating body 30 is bent in a substantially rectangular shape together with the link 32 due to the resistance of the swarf immediately after startup, but when the rotating body 30 reaches a predetermined high speed, the hammer 31 is turned off. Due to the centrifugal force, the link 32 and the hammer 31 take a straight posture, and the tip thereof approaches the blade 5 of the processing tank 2, so that the chips are crushed by the cooperation of the high-speed rotating hammer 31 and blade 5. The crushed chips are discharged from the discharge port 6 to the discharge hopper 45.

At this time, the striker 39 provided on the rotating body 30 guides the chips toward the inner peripheral wall surface of the processing tank 2, and supports the crushing action of the chips by the hammer 31 and the blade 5. The divider 8 attached to the lid plate 76
Numeral 0 disentangles the curled chips and supports the crushing action of the chips by the hammer 31 and the blade 5. Thereby, the crushing action of the chips is positively performed, and the crushing efficiency is enhanced.

In the case where foreign matter such as a piece of material generated by parting-off is mixed in the cutting powder introduced into the processing tank 2, as described above, the foreign matter detection control device detects the mixed foreign matter. Door 51 for discharging foreign matter based on the signal
Opening / closing control is performed. That is, when a solid matter larger than the swarf is mixed, not only a loud noise is generated but also the machine may be damaged. Therefore, at this time, the operation of opening and closing the door 51 for a certain period of time is repeated several times (for example, 5 to 6 times) to urge the discharge of the foreign matter from the foreign matter discharge port 7. This foreign matter discharging action is achieved not only by the hammer 31 but also by the striker 39.
Is also effective.

It is to be noted that the foreign matter is not always discharged from the foreign matter discharge port 7 but may be discharged from the chip discharge port 6. Therefore, when such a foreign substance discharge port 7 is separately set, the discharge probability including the foreign substance discharge from the chip discharge port 6 is doubled, and the foreign substance discharge effect can be improved. In this case, it is desirable that the operation of the machine is stopped if the foreign matter is not discharged even after the opening and closing operation of the door 51 of the foreign matter discharge port 7 is repeated a predetermined number of times.

As described above, according to the chip processing apparatus of the present embodiment, the oil separation processing of the chip and the subsequent chip crushing processing can be performed as a series of operations. The efficiency of the processing operation can be improved as compared with the case where the processing is performed by using. Further, since the entire device is covered by the soundproof wall 75, noise generated by the processing operation can be effectively prevented. Furthermore, since the chip processing device of the present embodiment is provided with the casters 8, it can be freely moved in the factory and its use place can be easily changed.

[0042]

As described in detail above, according to the present invention,
Since the oil separation processing of the chips and the crushing processing of the chips, which have been conventionally performed individually, can be continuously performed by one chip processing apparatus, the processing efficiency of the chips can be increased. In addition, when a soundproof wall is provided, noise generated during chip processing can be prevented from being released to the outside, and a striker for guiding chips toward the inner peripheral wall surface of the processing tank and a divider for breaking up chips are provided. In this case, the crushing efficiency of the chips can be increased. In addition, when foreign matter is mixed in, the foreign matter discharge port is opened to increase the probability of the mixed foreign matter being discharged, and the process from the detection of foreign matter to the discharge can be performed quickly, and the striker removes the crushed chips and foreign matter into the processing tank. It is guided to the inner peripheral wall surface side, so that its dischargeability can be improved.
