Description

  The present invention relates to a chip conveyor for conveying chips generated during machining by a cutting machine such as a band saw or a cutting machine such as a lathe, and more particularly, a scraper between endless chains provided in parallel. It is related with the chip conveyor which can prevent accumulation of the chip | tip between the said endless chain and the side part inner surface of the casing in a chip conveyor.

For example, a chip conveyor that conveys chips and chips generated by cutting a metal material with a cutting machine includes a screw-type chip conveyor and a scraper-type chip conveyor that includes a scraper. The scraper-type chip conveyor generally has a configuration in which both end sides of a scraper disposed between endless chains provided in parallel in a box-shaped casing are supported by the endless chain (see, for example, Patent Document 1).
JP 2005-254383 A

  A scraper-type chip conveyor is provided with a plurality of (two) endless chains in parallel in a box-shaped casing having an appropriate shape, and both end sides of the scraper disposed between both endless chains are supported by the endless chain. It is a configuration. Therefore, although the chips introduced into the casing and existing between the two endless chains are conveyed to the discharge port side by the scraper, the inside of the gap between the side part of the endless chain and the inner surface of the side part of the casing. Since the swarf that enters is not transported by the scraper, if it accumulates in large quantities, it may interfere with the smooth running operation of the endless chain, so it is necessary to periodically remove the accumulated swarf. There was a problem that the removal operation of the chips was relatively troublesome.

  The present invention was made in view of the conventional problems as described above, and provided with an introduction port for introducing chips into the inside on the one end side of the box-shaped casing, and on the other end side lower portion of the casing, A discharge port for discharging chips introduced from the introduction port to the outside, and a plurality of chain guides provided near the introduction port and a plurality of chain sprockets provided near the discharge port in the casing In order to convey the chips introduced from the introduction port to the discharge port, the chip conveyor is provided with a scraper supported at both ends by the parallel endless chain. The outer end of the endless chain is cut to convey chips that have entered between the endless chain and the inner surface of the side of the casing to the discharge port. And it is characterized in that it comprises a scrap conveying member.

  According to the present invention, even when chips enter the gap between the endless chain that supports the scraper and the inner surface of the side part of the casing of the chip conveyor, the gap is conveyed by the chip conveying member attached to the endless chain. The chip inside can be carried out to the discharge port, and the chip does not accumulate in the gap between the endless chain and the inner side surface of the casing.

  Referring to FIG. 1, a chip conveyor 1 according to an embodiment of the present invention includes a box-shaped casing 3, and an upper end of the casing 3 is cut by a cutting machine (not shown). An inlet 5 is provided for introducing the generated chips and chips. Further, a discharge port 7 for discharging chips introduced from the introduction port 5 to the outside is provided at the lower end of the other end side of the casing 3.

  A scraper 9 that circulates and moves in the casing 3 is provided in order to transport the chips introduced into the casing 3 from the introduction port 5 to the discharge port 7. More specifically, a rotating shaft 11 that is long in the left-right direction (a direction perpendicular to the paper surface in FIG. 1) is horizontally provided in the casing 3 near the introduction port 5. The rotating shaft 11 includes a plurality of chains. A sprocket 13 as an example of a guide is provided. In the casing 3 in the vicinity of the discharge port 7, a rotary drive shaft 17 that is rotationally driven by a motor 15 attached to the casing 3 is provided in parallel with the rotary shaft 11 and is rotatable.

  A plurality of drive sprockets 19 corresponding to the sprocket 13 are attached to the rotary drive shaft 17, and left and right endless long in the front-rear direction (left-right direction in FIG. 1) are attached to the drive sprockets 19 and the sprockets 13. Chains 21L and 21R are respectively hung. That is, the left and right endless chains 21L and 21R are provided in parallel, and the plurality of scrapers 9 are disposed between the endless chains 21L and 21R in parallel. The left and right ends of each scraper 9 are integrally supported by left and right endless chains 21L and 21R via brackets.

  The upper and lower sides through which the left and right endless chains 21L, 21R circulate are chain guides 23U, 23L which are respectively provided in the upper and lower longitudinal directions provided on the left and right side inner surfaces 3L, 3R of the casing 3 (see FIG. 2).

  By the way, although it illustrated about the case where the sprocket 13 was provided as an example of a chain guide, as a chain guide, it is also possible to set it as the disk-shaped or semicircle shaped chain guide fixed in the casing 3. FIG. In short, what is necessary is just to have a function of guiding and supporting the endless chains 21L and 21R circulated by the drive sprocket 19 rotated by the motor 15.

  In the above configuration, when the rotary drive shaft 17 is rotated forward by the motor 15, the endless chains 21L and 21R are rotated in the counterclockwise direction in FIG. 1 and introduced into the casing 3 from the introduction port 5. Chips are conveyed toward the discharge port 7 by the scraper 9 and discharged from the discharge port 7 to the outside.

  By the way, the chips introduced into the casing 3 from the introduction port 5 are not necessarily dropped and introduced between the left and right endless chains 21L and 21R, but the left and right sides of the lower chain guide 23L and the casing 3 The gap 25 between the inner surfaces 3L and 3R may enter. The chips that have entered the gap 25 are not transported by the scraper 9, and therefore stay in the gap 25. If a large amount of chips is accumulated, the smooth running action of the endless chains 21L and 21R is achieved. Will interfere.

  Therefore, in the present embodiment, as shown in FIGS. 3 and 4, the chips that have entered the gap 25 are carried out to the discharge port 7 on the outer side portions of the endless chains 21L and 21R in the left-right direction. An appropriate number of chip conveying members 27 are attached. In FIG. 4, the chip conveying member 27 is provided separately from the chain link in the endless chains 21 </ b> L and 21 </ b> R, but the chip conveying member may be provided integrally with the chain link. is there.

  With the above-described configuration, when the endless chains 21L and 21R are run as described above and the chips are conveyed from the inlet 5 side to the outlet 7 side by the scraper 9, the outer portions 21L and 21R are provided on the outer side. The chip conveying member 27 moves in the front-rear direction in the gap 25 between the chain guide 23L and the side inner surfaces 3L, 3R of the casing 3, and conveys the chips in the gap 25 to the discharge port 7 side. Will do.

  Therefore, a large amount of chips do not accumulate in the gap 25, and the smooth running of the endless chains 21L and 21R is not hindered, and the conventional problems as described above are solved. It is something that can be done.

It is side sectional explanatory drawing which showed notionally and schematically the whole structure of the chip conveyor which concerns on embodiment of this invention. It is front sectional explanatory drawing same as the above. It is explanatory drawing of the part provided with the chip conveyance member in the endless chain. It is sectional explanatory drawing same as the above.
