Abstract

PURPOSE:To lead minutely powdered chips which passed through a mesh belt, to the outside, by furnishing a coolant pan between the mash belt in a horizontal frame, and furnishing exhaust ports to lead out the coolant at the side walls of the horizontal frame. CONSTITUTION:Between the front side running part 12a and the rear side running part 12b of a mesh belt 12 in a horizontal frame 3, a coolant pan 15 is fixed and furnished. At both side walls 3a and 3b of the horizontal frame 3, plural exhaust ports 17 are opened successively, extending to connect the righthand and the lefthand edges of the coolant pan 15, to lead the coolant accumulated on the coolant pan 15 to the outside of a conveyer frame 1 and to release into a coolant tank 2. Therefore, minute chips which passed together with the coolant through the mesh belt 12 at the upper side running part 12a in the horizontal frame 3 can be led to the outside through the coolant pan 15 and the exhaust ports 17.

Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention provides an endless mesh belt inside a horizontal frame and an inclined frame, and conveys and removes chips in the coolant by rotating this belt. This invention relates to a chip conveyor.

(Prior Art) Since mesh belts have good capture efficiency for granular chips mixed in coolant, chip conveyors using mesh belts have been proposed in recent years in place of conventional hinge belts made of steel plates.

(Problem to be Solved by the Invention) However, when using this mesh belt, the size of the mesh belt cannot be made very small due to the need to ensure coolant passage, so fine powder chips do not pass through the coolant. At the same time, there is a problem in that it easily passes through the mesh of the mesh belt and accumulates on the bottom of the conveyor frame, making removal work very troublesome.

Structure of the Invention (Means for Solving the Problems) The present invention has been made by focusing on the above-mentioned problems. A coolant pan is installed to receive the coolant that has passed through the front running part of the frame, and a discharge port is installed on the side wall of the horizontal frame to connect to the coolant pan to lead the coolant on the coolant pan to the outside. Ta.

(Operation) According to this solution, the fine powder chips that have passed through the upper mesh belt in the horizontal frame together with the coolant are led out to the outside of the conveyor frame via the coolant pan and the discharge port.

(Example) An example embodying the present invention will be described below with reference to FIGS. 1 to 4.

As shown in No. 1.2ffl, the conveyor frame 1 is
a horizontal frame 3 placed on the coolant tank 2;
The entire frame is constructed in the form of a gutter, with an inclined frame 4 extending obliquely upward from the tip of the horizontal frame 3. A pair of driving sprocket wheels 6 are provided in the upper end of the inclined frame 4, which are rotated by a motor 5, while a pair of driven sprocket wheels 7 are provided in the starting end of the horizontal frame 3. As shown in FIG. 3, between the two sprocket wheels 6.
．． A chain 10 that is guided by 9 and goes around the frame 1 is hung thereon. A large number of link plates 11 are attached to the chain 10 to prevent the coolant from flowing out to the side, and endless nylon mesh belts 12 are fixed to the link plates 11 at both ends thereof. ing. Further, on the mensch belt 12, a plurality of scrapers 13 are arranged at approximately equal intervals so as to be perpendicular to the direction of conveyance of the chips, in order to mainly push up large chips within the inclined frame 4. Therefore, this mesh belt 12 is rotated within the conveyor frame 1 as the motor 5 is driven, and after capturing and removing chips from various machine tools etc. that are dropped together with coolant from above the horizontal frame 3, the chips are transferred to the horizontal frame 3. From there, it is conveyed to the upper end of the inclined frame 4 and discharged downward through an opening 14 provided on the lower surface thereof.

Now, as shown in FIG. 3, between the front running part 12a and the back running part 12b of the mesh belt 12 in the horizontal frame 3, there is a coolant pan for receiving the coolant that has passed through the front running part 12a of the mesh belt 12. 15 are fixedly arranged so as to divide the interior of the horizontal frame 3 into upper and lower sections over almost the entire length thereof, and upright pieces 16 (only one shown) are provided at both front and rear ends for regulating the outflow of coolant.
is formed by bending. A plurality of discharge ports 17 are continuously opened in both side walls 3a and 3b of the horizontal frame 3 so as to connect and extend to the left and right side edges of the coolant pan 15, and the coolant accumulated on the coolant pan 15 is discharged onto a conveyor. The coolant can be led out of the frame 1 and discharged into the coolant tank 2.

On the other hand, as shown in FIG. 4, between the front side running part 12a and the back side running part 12b of the mesh belt 12 in the middle part of the inclined frame 4, an injection pipe 19 having a large number of nozzles 18 is perpendicular to the conveyance direction. The coolant is pumped up from the coolant tank 2 by a pump (not shown) and injected toward the back side running portion 12b of the mesh belt 12 and the scraper 13 through the nozzle 18, and the back side of the belt 12 is Fine chips adhering to the traveling section 12b and the scraper 13 can be cleaned. A recovery tank 20 for recovering the coolant and fine chips after cleaning is disposed on the bottom wall of the inclined frame 4 at a position corresponding to the injection pipe l9, and the collected coolant and chips are collected again on the bottom surface of the tank 20. Table IJ of mesh belt 12 in horizontal frame 3
A return pipe 21 is provided for transferring onto the running section 12a.

Effects of the Invention As detailed above, according to the present invention, the fine powder chips that have passed through the mesh belt on the upper side of the horizontal frame together with the coolant are led out to the outside of the conveyor frame via the coolant pan and the discharge port. Therefore, the accumulation of chips at the bottom of the horizontal frame is prevented, and the troublesome work to remove them becomes unnecessary, which is an excellent effect.
