  In the conventional coil conveyor apparatus, when many metal chips are received, clogging may occur at the discharge port. And such a clogging may cause failure of the coil conveyor device.

  An object of the present invention is to provide a coil conveyor device that can prevent clogging at such a discharge port and can stably discharge metal chips.

  The inventors have also found that the principle of the present invention can be applied to a screw conveyor device. That is, the further objective of this invention is providing the screw conveyor apparatus which can prevent the clogging at the above discharge ports and can discharge | emit metal chips stably.

  The present invention includes a receiving member that can receive metal chips from a machine tool, and a coil portion that is provided inside the receiving member and is driven to rotate. Metal chips from a machine tool are received by the receiving member. A coil conveyor device configured to feed the metal chips out of the receiving member by rotationally driving the coil portion, and the receiving member is provided with discharge ports in two regions, respectively. The coil portion has an integral coil configured such that the twist direction on one side and the twist direction on the other side are different, and an end portion on one side of the integral coil is one discharge port. The coil conveyor device is characterized in that the other end of the integrated coil is located on the other discharge port side.

  According to the present invention, since a large amount of metal chips does not concentrate at a single discharge port of the coil conveyor device, clogging at the discharge port is effectively prevented. In particular, as the coil portion, an integral coil configured so that the twist direction on one side and the twist direction on the other side are different is used, and therefore the integral coil can be driven by a single drive system (for example, an electric motor). Nevertheless, metal chips can be sent out almost uniformly toward the two discharge ports, although the conventional drive system can be used.

  But the aspect isolate | separated into the one side coil and the other side coil from which a twist direction mutually differs may be employ | adopted as a coil part. That is, the present invention includes a receiving member that can receive metal chips from a machine tool, and a coil portion that is provided inside the receiving member and is driven to rotate, and receives the metal chips from a machine tool. The coil conveyor device is configured to send the metal chips to the outside of the receiving member by rotationally driving the coil portion while being received by the member, wherein the receiving member has two outlets in each of the two regions. The coil portion has one side coil and the other side coil having different twist directions, and one end portion of the one side coil is located on one discharge port side. The coil conveyor device may be characterized in that the other end of the other coil is located on the other discharge port side.

  In this case, it is preferable that the other end portion of the one-side coil and the one end portion of the other-side coil are close to each other and located in the central portion of the receiving member.

  In the present invention as described above, it is more preferable that the bottom surface of the receiving member is configured to be inclined so as to descend toward each discharge port.

  Moreover, it is preferable that the pitch of the coil is gradually increased when viewed in the direction toward each discharge port.

  Moreover, it is preferable that the diameter of the coil is gradually increased when viewed in the direction toward each discharge port.

  Further, it is preferable that one or more auxiliary coils having different outer diameters are concentrically disposed on the coil. In this case, it is preferable that the coil and the auxiliary coil are driven by a common drive system.

  According to the present invention, since a large amount of metal chips does not concentrate at a single discharge port of the coil conveyor device, clogging at the discharge port is effectively prevented.
