Had been transformed. Further, in addition to the surface of the transport guide cylinder, the weight of the entire transport apparatus and the cost are increased because of the structure in which the magnetic body is provided inside the transport guide cylinder.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a small, lightweight and inexpensive transfer device for transferring a transfer target by magnetic force.
[0005]
[Means for Solving the Problems]
The configuration, operation and effect of the invention according to claim 1 are as follows.
[0006]
〔Constitution〕
A non-magnetizable transfer guide tube, a magnetic body positioned inside the transfer guide tube and exerting a magnetic force on a transfer target outside the transfer guide tube, and a transfer target magnetic material at a transfer end portion of the transfer guide tube. And a fluid port provided in the transport guide cylinder, and the fluid port feeds a fluid from a fluid supply device into the transport guide cylinder to move the magnetic material by fluid pressure to the transport guide cylinder. It is configured to reciprocate within.
[0007]
[Action]
The fluid supplied to the transport guide cylinder by the fluid port reciprocates the magnetic body between the transport start end and the transport end within the transport guide cylinder. When the magnetic material moves forward from the transport start end, the object to be transported, such as chips, is attracted to the outer peripheral surface of the transport guide cylinder due to the magnetic force of the magnetic material, and moves along the transport guide cylinder with the magnetic material. . When the transport object reaches the transport end, the magnetic body returns to the transport start end side so as to re-transport the transport object. At this time, the object to be conveyed is separated from the magnetic material by the separating body, and does not return to the conveyance start end side with respect to the magnetic material.
This makes it possible to adopt a small-diameter transport guide tube that allows the magnetic material to enter the reciprocating movement inside and allow the fluid to flow, and to simply position the magnetic material reciprocally inside the transport guide tube. By adopting a simple magnetic material interior structure, the transport target can be transported by the magnetic force of the magnetic material.
[0008]
〔effect〕
Therefore, it is possible to obtain an inexpensive device by using a small-diameter transport guide cylinder and a simple magnetic material interior structure while transporting an object to be transported by magnetic force, and to reduce the size and weight of the entire apparatus. And can be easily installed in a narrow installation space.
[0009]
The configuration, operation and effect of the invention according to claim 2 are as follows.
[0010]
〔Constitution〕
In the configuration according to the first aspect of the present invention, an object to be conveyed separated from the magnetic body at an upward surface portion of the outer peripheral surface of the transport guide cylinder is guided to the separation body so as to descend to a downward surface of the outer peripheral surface of the transport guide cylinder. It has a guide part to perform.
[0011]
[Action]
Even if the object to be transported that has reached the transport terminal end portion is separated from the magnetic material on the upwardly facing surface portion of the outer peripheral surface of the transport guide cylinder, the guide portion may be lowered to the lower surface side of the outer peripheral surface of the transport guide cylinder. And easily fall from the transport guide tube. As a result, the object to be conveyed remains on the conveyance guide cylinder even after being separated from the magnetic material at the conveyance end portion, and is attracted to the magnetic material returning to the conveyance start end side and returned to the conveyance start end side. Is transported while minimizing the occurrence of blemishes.
[0012]
〔effect〕
Therefore, when the transport object flows backward from the transport end side to the transport start end side, the transport efficiency is likely to be reduced or clogged due to the reverse flow, but the transport can be smoothly performed so that the transport trouble hardly occurs.
[0013]

[0016]
As shown in FIG. 4, the pair of magnets 13 are permanent magnets fixed between a pair of piston bodies 17 a of one piston 17 slidably provided inside the transport guide cylinder 12. The cylinder 12 reciprocates with the piston 17 inside the transport guide cylinder 12 over the transport end side where the separator 14 is attached and the transport start end side opposite to the transport end side. When moving inside the cylinder 12, it moves while applying a magnetic force to the chips located outside the conveyance guide cylinder 12 via the conveyance guide cylinder 12. That is, the chips located outside the transport guide cylinder 12 can be attracted to the cylindrical outer peripheral surface of the transport guide cylinder 12 due to the magnetic force of the magnet 13 and move along the magnet 13 along the cylindrical outer peripheral face. I have to.
[0017]

Is controlled so as to be alternately selected. The air port 16 on the input side port sends the compressed air supplied from the air supply device 21 via the pipe line 20 into the inside of the transport guide tube 12, and the air port 16 on the output side port. Discharges the pressurized air inside the transport guide tube 12 to the air supply device 21 via the pipe 20. Thus, when air is supplied from the air supply device 21 to the air port 16 located at the end of the conveyance guide tube 12 on the conveyance start end side, the air is sent into the conveyance guide tube 12. By sliding the piston 17 toward the transport end of the transport guide tube 12 by this air pressure, the magnet 13 is moved forward from the transport start end side of the transport guide tube 12 to the transport end side by the air pressure from the air supply device 21. When air is supplied from the air supply device 21 to the air port 16 located at the end of the conveyance guide tube 12 on the conveyance end side, the air is sent into the inside of the conveyance guide tube 12 and the air pressure is applied. By sliding the piston 17 toward the transfer start end of the transfer guide tube 12, the magnet 13 is moved back from the transfer end side of the transfer guide tube 12 to the transfer start end by air pressure from the air supply device 21.
[0018]
The separator 14 is made of a synthetic resin and is externally fitted to the transport guide tube 12 so as not to be magnetized by the action of the magnet 13. As shown in FIG. 5 and the like, the separation body 14 is located at an end of the conveyance guide tube 12 facing the conveyance start end, outside the upwardly facing surface portion of the cylindrical outer peripheral surface of the conveyance guide tube 12.

It has an end face. When the chips are attached to the magnet 13 and move along the cylindrical outer peripheral surface of the transport guide tube 12 and reach the transport end portion of the transport guide tube 12, the chips come into contact with the guide portion 14a or the separation operation portion 14b, and thereafter, The magnet 13 is configured to be transported beyond the guide section 14a and the separation operation section 14b of the separation body 14 and further toward the end of the transport guide tube 12. Thereby, the separating body 14 separates the chips that have reached the transport end of the transport guide tube 12 from the magnet 13 by the stopper action of the pair of guide portions 14a and the separation operation portion 14b, and drops the chips from the transport guide tube 12.
[0019]
As shown in FIG. 5, the pair of guide portions 14a are inclined with respect to the moving direction of the magnet 13 and at a lower level toward the lower side in the chip transfer direction. As a result, the respective guide portions 14a of the separation body 14 are capable of removing chips separated from the magnet 13 at the upward portion of the cylindrical outer peripheral surface of the transport guide tube 12 due to the inclined shape of the guide portion 14a. It is guided so as to descend to the lower surface side of the outer peripheral surface of the cylinder, so that chips are easily dropped from the upper surface portion of the transport guide tube 12.

It moves forward from the start end to the transport end. Then, the chips that have fallen from the chip discharging portion 2 of the machine tool 1 to the transport start end side of the transport guide cylinder 12 are attracted to the outer peripheral surface of the transport guide cylinder 12 by the magnetic force of the magnet 13, and are transported by the magnet 13. It moves along the guide tube 12. At this time, even if the chip is separated from the magnet 13 and falls, the chip is received by the chip receiver 11 so as not to fall to the ground. When the chips reach the transport end of the transport guide tube 12, the separator 14 separates the chips from the magnet 13. Thereafter, in order to switch the air supply by the air supply device 21, the air port 16 on the conveyance end side sends air from the air supply device 21 into the inside of the conveyance guide tube 12, and the pair of magnets 13 is conveyed by the air pressure. The inside of the guide tube 12 moves from the transport end side to the transport start side. At this time, the chips separated first from the magnet 13 are discharged from the machine tool 1 to the transfer start end side by dropping from the transfer guide tube 12 to the carry-out port 18 and not attaching to the magnet 13 to return to the transfer start end side. The chips are transferred to the end of conveyance by the magnetic force of the magnet 13 and supplied to the chip container 3.
