The present invention relates to a chip conveying conveyor for discharging the cutting chip discharged from the machine tool by the endless member, and more specifically, using the endless member having a permanent magnet to transfer the chip by a magnetic force, but the chip transfer unit and The drive part of the endless member is completely separated so that it does not interfere with the circumferential motion of the endless drive part by the chip or the coolant, and it is possible to make a separate device unnecessary to separate the coolant and the separation chip.

In general, the cutting chips and cutting tools generated during the cutting of metal materials in machine tools are transferred to the chip conveying Kenvey from the machine tool, so that the cutting chips are treated as industrial waste and the coolants are recycled. Stored.

Conventional chip conveying conveyors include a hinge belt type for driving a chain provided on an endless hinge belt and a rear surface of the hinge belt using a sprocket, a type for transferring chips using a screw, and a type of using a permanent magnet and a hinge belt. In the case of using a permanent magnet and a hinge belt, the Korean Patent Publication No. 1988-0002389 describes, "The chip 9, such as cutting chips, is transported by the endless movement of the endless conveying member 4, and its conveying range. In the chip conveying conveyor to be discharged from the end of the chip is installed at a predetermined position of the conveying member (4) and accommodated inside the magnet receiving body (8) and at least one magnet receptor (8) extending in its width direction At the time of carrying out, it is maintained at the adsorption position close to the inner wall surface of the magnet receptor, and at the time of taking out the chip, it is based on the inversion operation of the emitting member That is characterized by being a non-permanent magnet (S₂) to move to the suction position there is known, as in Fig. 1 to Fig. 2 to the liver.

However, in the case of the chip conveying conveyor having the configuration as described above, when the chip is conveyed by the hinge belt, the chip or coolant penetrates into the gap between the belt and the belt, which may cause the rotational movement of the conveyor or the chip which is included in the coolant. It should be equipped with a filtration device such as a filter for separation. In the case of the chip conveyance by the rotation of the screw, the chip discharged long in the coil is wound on the screw, which causes the failure, and also the conveying conveyor using the endless conveying member and the magnet acceptor. Penetration of powdered chips between the endless transfer members could not be excluded, and there was a problem in that the construction of the magnet receptor was complicated and the manufacturing and maintenance were difficult.

The present invention has been made in order to solve the above-mentioned problems, the object is to completely remove the transfer portion of the chip and coolant and the driving unit of the chip conveying conveyor so that the circumferential operation of the driving unit is not affected by the separation chip or coolant. It is done.

Yet another object of the present invention is to completely separate the separation chips contained in the coolant into permanent magnets for chip transfer, thereby eliminating the need for a separate device for separating the coolant and separation chips.

It is still another object of the present invention to provide a chip conveying conveyor which is capable of efficiently recovering chip chips by eliminating failures with a simple configuration.

It is still another object of the present invention to provide a chip conveying conveyor which makes it possible to reliably adsorb and detach chips from permanent magnets.

Magnet conveyor for the present invention for conveying the chip for the above object is extended in the horizontal direction for accommodating the chain and the sprocket and the end of one side to receive the chip and the coolant on the top of the frame and frame formed obliquely upward in the oblique direction The receiving portion is formed to form a movable transfer path, and the upper surface and the receiving portion of the frame are isolated to maintain airtightness so that the coolant does not leak.

One or more inlets for inserting the chip and the coolant are formed in the upper part of the accommodating part, and one side of the accommodating part is formed with an outlet for discharging the coolant at a predetermined height from the bottom of the accommodating part.

The permanent magnet on the rod is provided at right angles to the circumferential direction of the chain at regular intervals between the chain and the chain rotated by the drive motor and the chain sprocket, and the permanent magnet has a quadrilateral cross section. One plane is mounted so as to be close to the top surface of the frame, that is, close to the bottom surface of the receiving portion.

The material of the accommodating part that accommodates the frame, the chip and the coolant is made of high permeability and made of non-magnetic stainless steel. When the permanent magnet enclosed by the frame is circulated by the chain, the chip contained in the accommodating part is formed by the permanent magnet. The magnetic force is lost by the chain returned from the upper part of the moving path inclined in the upper direction of the frame as it moves along, and falls by its own weight.

The coolant that is injected with the chip into the inlet is received at a certain level in the receiving part, and the chips of the powder contained in the coolant sink faster and move according to the magnetic force due to the magnetic force acting on the floor. Discharged through the outlet provided on the side.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a side cross-sectional view of the magnet conveyor for chip transport of the present invention, Figure 3 is a plan view of Figure 2, Figure 4 is a partial cross-sectional view of the magnet receptor and chain embedded in the frame of the present invention, Figure 5 is It is AA line sectional drawing, and FIG. 6 is BB line sectional drawing of FIG.

The accommodating part 14 accommodating the chip and the coolant has a structure capable of maintaining airtightness so that the coolant does not leak, and the frame 12 accommodating the chain 11 and the upper surface of the frame 12, namely, The structure is completely isolated with respect to the bottom surface of the receiving portion 14.

At least one inlet 13 through which chips and coolants are inserted is formed in the upper part of the accommodating part 14, and at one side of the accommodating part 14, a coolant is formed at a predetermined height at the bottom of the accommodating part 14. An outlet 15 is formed to allow discharge.

In addition, the bottom surface of the accommodating part 14 performs a function of a moving path in which the chip is embedded in the frame and absorbed by the permanent magnet magnetic force of the magnet acceptor 16 that is circulated by the chain 11 to move along the chain. do.

The chains 11 embedded in the frame 12 are arranged side by side in two rows along both sides of the frame 12 and may be circulated by the driving motor 17 and the sprocket 18 provided at the top of the inclined portion of the frame 12. It is configured so that, between the chain 11 and the chain 11 is provided with a magnet receptor 16 for receiving the permanent magnet 19 at a predetermined interval at a right angle to the circumferential direction of the chain, provided in the chain 11 The distance between the magnet receptor 16 is preferably spaced about 30 cm, but is not limited thereto.

The magnet receptor 16 provided in the chain 11 is configured in the shape of a quadrangular rod, and the upper surface of the magnet receptor 16 can be turned around at the bottom of the receptor, that is, close to the upper surface 20 of the frame. The chip deposited on the bottom surface of the receiving portion 14 can be attracted with stronger magnetic force to move along the magnet receptor 16.

Therefore, in order to maintain the bottom surface of the magnet receiver 16 and the receiving portion 14 at a predetermined interval, the chain 11 is configured to be constrained and wound around the chain guide 21 fixed to the side of the frame 12. do.

In addition, the material constituting the frame 12 and the receiving portion 14 is a high permeability, is composed of a non-magnetic material, and aluminum or synthetic resin can be used, but is preferably made of stainless steel in consideration of strength and durability. .

When the chip embedded in the frame 12 and adsorbed by spaced apart from the bottom surface of the accommodating portion 14 to the magnet receptor 16 that is driven by the chain 11 reaches the tip of the inclined portion of the frame 12, the chain 11 ) Returns along the frame 12, so that the chip adsorbed to the magnet acceptor 16 loses the attraction force and falls by its own weight.

The coolant injected together with the chip into the inlet 13 is accommodated until the water level is reached at the receiving portion 14, and the chips of the powder contained in the received coolant are settled more quickly by the magnetic force acting on the bottom surface. The chips of the separated powder are attracted to the magnetic force and moved, and the coolant of a predetermined level or more is discharged to the discharge port 15 provided on the side of the receiving portion 14.

Therefore, the discharged coolant does not contain powdered chips and can be recycled to the cutting operation without the need for a separate filtration process.
