BRIEF DESCRIPTION OF THE DRAWINGS FIG.
FIG. 1 is a schematic view of a chip collecting device according to one embodiment of the present invention. In the present embodiment, a conveyor device 40 for transferring chips from a cutting oil pool 60 in which chips and cutting oil are stored onto a cutting oil surface is provided. As the cutting oil pool 60, one that is partitioned into a plurality of partition chambers by several partition plates 62 is used. In the cutting oil pool 60, the cutting chips and cutting oil sent via the transfer gutter 50 and the like are supplied to the partition chamber formed at the end by the transfer gutter 50. This is for preventing the chips which have settled on the bottom surface of the cutting oil pool 60 from diffusing and separating the chips from the cutting oil.
The separated cutting oil is supplied to the partition plate 6 for partitioning the partitioning chamber at the end.
After entering the partitioning room one after another, dust and the like are separated and reused by a pump (not shown) for a machine tool or the like.

A conveyor device 40 for transferring chips settled on the bottom surface of the cutting oil pool 60 is disclosed in
No. 125368 discloses a magnet roller, that is, a device in which magnet rollers 42, 44 and 46 in which a magnetic material is sealed in an outer cylinder made of a non-magnetic material are connected in multiple stages. In addition, as the conveyor device 40,
A chain conveyor that circulates a wire net can be used. In this case, the chain conveyor is provided with the cutting oil pool 60.
And forms a circulation path which rises obliquely from a horizontal portion disposed horizontally on the bottom surface of the cutting oil and terminates on the cutting oil surface. In such a chain conveyor, chips which are transferred to the cutting oil pool and settle in the cutting oil are received by the horizontal portion of the chain conveyor and transferred onto the cutting oil surface.

In addition, near the end of the conveyor device 40 located on the cutting oil surface of the cutting oil pool 60, a chip transfer table 10 having an inclined surface 12 extending obliquely upward is provided. When the swarf formed by storing the swarf conveyed by the conveyor device 40 at the lower end portion of the sloping surface 12 is transferred, the cutting oil contained in the swarf is drained. Is an inclined surface for performing the following. Therefore, the longer the entire length of the inclined surface 12 is, the better the oil removal from the chip lump can be performed. However, as will be described later, the moving means 16 for moving the chip transfer tool 14 for transferring the chip lump. Is preferably in the range of 40 to 100 cm in relation to the stroke length. It is preferable that the inclination angle of the inclined surface 12 is also set to 35 to 55 ° in order to perform excellent drainage of the cutting oil contained in the chip mass. Further, the lower end of the inclined surface 12 is provided with a storage section for storing the chips transferred to the conveyor device 40, so that the chips can be smoothly transferred from the conveyor device 40 to the chip transfer table 10. Can be. In addition, slope 1
Is transferred to the upper end along the 2, Setsukokatamari that has reached the upper end of the inclined surface 12 is discharged into chips transport carriage 70.

[0010] On the inclined surface 12 of the chip transfer table 10, a chip transfer tool 1 for transferring a chip lump along the inclined surface 12.
4 are provided. The chip transfer tool 14 is provided on the inclined surface 1.
2 is provided so as to be movable in the upper and lower direction, and when moving in the upper direction of the inclined surface 12, at least a part thereof slides on the inclined surface 12, and the chip lump moves in the upper direction along the inclined surface 12. Transfer to For this reason, as the chip transfer tool 14,
A plate-like body or a brush-like body at least partly in sliding contact with the inclined surface 12 can be used. When the plate-like body is used as the chip transfer tool 14, the inclined surface may be formed by forming a slit or a sawtooth-shaped wave-shaped portion on the sliding contact surface with the inclined surface 12, or by forming a punching hole in the plate-like body. The cutting oil flowing out of the swarf mass transferred upward along the line 12 can easily flow down to the cutting oil pool 60. Further, when the plate-like body is formed of an elastic material such as rubber, when the chip lump is transferred to the upper end direction along the inclined surface 12, the chip lump is subjected to a squeezing action due to the plate-like body, and the chip lump is formed. The cutting oil contained in the lump can be squeezed.

By the way, when the chip transporter 14 having moved the chip lump along the inclined surface 12 toward the upper end moves toward the lower end of the inclined surface and returns to the initial position, the lower end of the inclined surface 12 Chip mass is present. Therefore, when the chip transfer tool 14 moves in the lower end direction along the inclined surface 12, the chips stored at the lower end of the inclined surface 12 are swept again into the cutting oil pool 60. In this regard, in this embodiment, as shown in FIG. 1, a guide member 22 for guiding the chip transferring tool 14 moving below the inclined surface 12 is provided. Guide member 2 shown in FIG.

And a fixed portion 26 provided . The rotating part 24 shown in FIG. 1 has one end in contact with the inclined surface 12 and is rotatable in the direction of arrow B. Therefore, the chip transfer tool 1
2 moves toward the upper end along the inclined surface 12, FIG.
As shown in (2), the rotating portion 24 of the guide member 22 comes into contact with the chip transporter 14 and rotates upward to pass the chip transporter 14. Note that the fixing portion 26 is provided at a position that does not come into contact with the chip transferring tool 14 that moves in the upper end direction along the inclined surface 12.

Meanwhile, when the chips transfer tool 14 from the upper end of the inclined surface 12 is returned to the mobile originally located below edge direction of the inclined surface 12, since the one end of the rotating portion 24 is in contact with the inclined surface 12 As shown in FIG. 3, the chip transferring device 14 moves downward along the upper surfaces of the rotating portion 24 and the fixed portion 26 away from the inclined surface 12. In this manner, the chip transfer tool 14 returns to the initial position away from the inclined surface 12, so that the chip transfer tool 14 moves upward along the inclined surface 12 as shown in FIG. 12 chips lumps formed at the lower end of the chip transfer tool 14 to move down edge direction can be avoided to re-fall cutting oil pool 60, it is performed collecting chips smoothly it can.

Such a rod 2
It is preferable that the length of 0 is equal to the length of the inclined surface 12 because control means for controlling the extension length of the rod 20 is not required. Further, the extension / contraction cycle of the rod 20 can be easily controlled by a timer or the like.

In the apparatus shown in FIG. 1, the swarf formed by being transferred from the cutting oil pool 60 and accumulated by the conveyor device 40 is formed on a horizontal portion provided at the lower end of the inclined surface 12 by the cylinder device 16. The rod 20 is extended and moved in the upper end direction along the inclined surface 12 by the chip transfer tool 14 to cut off the cutting oil contained in the chip mass. At this time, the cylinder 17 of the cylinder device 16 is rotated upward around the other end of the cylinder 17 rotatably mounted on the fixed wall 18 as shown in FIG. In addition, the chip transfer tool 14
Without contacting the fixed portion 26 of the guide member 22 moves upward end along the inclined surface 12, in contact with the rotating portion 24 of the guide member 22. As shown in FIG. 2, the rotating unit 24 is rotated about the rotation shaft 28 by the chip transfer device 14 and passes the chip transfer device 14 that pushes up the chip mass. In addition, the rod 20 is extended to
The along the inclined surface 12 is moved upward end direction, the inclined surface 12
The lump of chips is discharged to a chip carrier 70 from the upper end of the chip. The cutting oil contained in the discharged swarf lump is formed on the inclined surface 12.
By moving the cuttings mass in the upper end along the,
Since the oil is sufficiently drained, it can be reduced as much as possible, and the discharged chips can be easily handled. When the chip moving device 14 pushes up the chip lump along the inclined surface 12, as shown in FIG. 2, the horizontal portion provided at the lower end of the inclined surface 12 is cut by the conveyor device 40. The powder is stored.

Next, one end of the rotating portion 24 of the guide member 22 is in contact with the inclined surface 12 when the compressed chip transferring tool 14 of the rod 20 of the cylinder device 16 is moved below the inclined surface 12. As shown in FIG. 3, the chip transferring tool 14 moves toward the lower end along the upper surfaces of the rotating part 24 and the fixed part 26 and returns to the initial position. For this reason, the chip lump formed at the horizontal portion provided at the lower end of the inclined surface 12 is
Thus, it is possible to avoid a situation in which the chips are swept down into the cutting oil pool 60, and it is possible to shift to a system for smoothly transferring the chip lump along the inclined surface 12 toward the upper end.
