DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment in which the present invention is embodied in a chip conveyor will be described below with reference to FIGS.

As shown in FIG. 1, a chip conveyor 11 according to the present embodiment includes a housing 12 arranged near a machine tool (not shown) such as a lathe, and a conveyor 13 housed in the housing 12. ing. The housing 12 includes a lower horizontal portion 12a horizontally extending from a base end side to a distal end side (from right to left in FIG. 1), and a rising portion 12 obliquely extending upward from a distal end portion of the lower horizontal portion 12a.
b, and an upper horizontal portion 12c extending horizontally from the upper end portion of the rising portion 12b to the distal end side, and is formed so that the overall shape is substantially horizontal when viewed from the side. The lower horizontal portion 12a has an opening 12d formed on the base upper surface, and the upper horizontal portion 12c has a chip outlet 12e formed on the lower surface thereof. The lower horizontal portion 12a
A coolant discharge port (not shown) for discharging the coolant accumulated in the lower horizontal portion 12a is formed in the vicinity of the upper portion of the side wall.

Inside the housing 12, sprockets 14a and 14b are rotatably supported at the base end of the lower horizontal portion 12a and the tip end of the upper horizontal portion 12c, and between the sprockets 14a and 14b. An endless conveyor 13 is mounted. The conveyor 13
When a drive motor (not shown) is driven, the motor orbits counterclockwise in FIG.

The conveyor 13 includes an endless conveyor body 17 having a large number of hinge plates connected via a link mechanism, and a scraping plate 15 erected at predetermined intervals on the surface of the conveyor body 17. Have. In addition, in the conveyor main body 17 of the present embodiment, detailed illustration of the hinge plate and the like is omitted. The scraping plate 15 is formed in a flat plate shape and has the same width as the conveyor 13. FIG.
As shown in FIG. 5, triangular projections 16 are formed at three positions in the vicinity of both ends and the center of the upper end surface of the scraping plate 15, and the tip of the projection 16 is an edge 16a.

Next, the operation of the chip conveyor 11 of the present embodiment configured as described above will be described.
For example, when the coolant C into which the curling cutting chips T are mixed flows into the opening 12 d of the housing 12, the cutting chips T sink on the conveying surface of the conveyor 13. Then, the cutting tip T is locked by the scraping plate 15 of the conveyer 13 that is rotating and driven, and the upper horizontal portion 12c
Conveyed toward.

Then, the cutting tip T is raised to the rising portion 12b.
, The inclination of the scraping plate 15 is inclined in the horizontal direction by an amount corresponding to the inclination of the rising portion 12 b, so that the cutting chips T locked on the scraping plate 15 try to get over the scraping plate 15. However, since the cutting tip T is caught on the tip of the projection 16 formed at the upper end of the scraping plate 15, that is, the edge portion 16a, the cutting tip T is reliably conveyed without going over the scraping plate 15. When the cutting tip T is transported to the tip of the upper horizontal portion 12c,
When the conveyor 13 is inverted, the cutting tip T
Is discharged from the chip discharge port 12e into a collection box (not shown) arranged below the discharge port 12e.

Accordingly, the chip conveyor 11 of the present embodiment
According to this, the following features can be obtained. (1) In the present embodiment, a projection 16 is formed on the upper end surface of the scraping plate 15 with the tip being an edge 16a. Therefore, even if the curling-shaped cutting tip T tries to climb over the scraping plate 15 at the rising portion 12b, the cutting tip T is hardly climbed over the scraping plate 15 by being caught by the edge 16a at the tip of the projection 16. Therefore, the conveyor 13 can reliably transport the cutting chips T even when passing through an inclined portion such as the rising portion 12b.

(2) In the present embodiment, since the cutting chips T do not climb over the scraping plate 15 of the conveyor 13 in the rising portion 12b, the cutting chips T do not accumulate below the rising portion 12b. Therefore, the plurality of cutting chips T do not accumulate at the base end of the rising portion 12b to form a chip lump. In addition, since the chip lump is not formed, the chip lump K is moved upward as in the conventional chip conveyor 51.
Since there is no conveyance while compressing between the upper inner side surface of a and the surface of the conveyor 53, the driving means for driving the conveyor 13 is not overloaded.

(Alternative Example) The above embodiment may be modified as follows. In the above-described embodiment, the projection 16 having the edge 16a is formed on the upper end surface of the scraping plate 15. This is, as shown in FIG.
A projection 16 having 6a may be formed. With this configuration, even if, for example, a curling cutting tip gets over the scraping plate 15 in the rising portion 12b, the cutting tip 15 is caught by the tip of the projection 16 adjacent to the scraping plate 15 on the side opposite to the transport direction, that is, the edge portion 16a. Can be transported.

As shown in FIG. 4, the projection 16 of the above embodiment may be formed so as to protrude in the transport direction from near the upper surface of the scraper 15 in the transport direction. Even if formed in this way, the same effects as in the above-described embodiment can be obtained.

In the above-described embodiment or each of the above examples, the triangular projection 16 is formed, and the tip of the projection 16 is the edge 16a. However, the shape of the projection is quadrilateral or the like. Any shape may be used as long as an edge is formed at the corner or corner. Even with such a configuration, the same effects as those of the above-described embodiment or each of the above-described different examples can be obtained.

In the above-described embodiment and each of the above examples, one projection plate 15 or three projections 1
Although 6 is formed, any number may be provided. Even in this case, the same effects as those of the above-described embodiment and each of the above-described examples can be obtained.

As shown in FIG. 5, a substantially circular hooking concave portion 20 may be cut out from the upper edge of the scraping plate 15, and a corner formed by the hooking concave portion 20 may be an edge portion 20 a. In this case, the shape of the hooking concave portion 20 is not limited to a substantially circular shape, but may be any shape such as a square shape such as a square shape or an indefinite shape as long as it forms an edge-shaped corner. Further, in FIG. 5, the number of the hooking concave portions 20 is three, but any number may be formed. Even when formed in this manner, substantially the same effects as in the first embodiment can be obtained.

Next, technical ideas that can be grasped from the above embodiment and other examples will be described together with their effects. (B) The hooking means has a sharp edge portion in a direction orthogonal to the conveying direction of the conveyor or in the conveying direction of the conveyor. Conveyor described. This way,
The cutting tip can be reliably hooked at the edge.
