Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a granular material conveying device that rotates a spiral body within a groove having a substantially semicircular cross section to convey the granular material within the groove.

``Prior Art'' As a conventional powder conveyance device, there is one that is connected to a machine tool and used for collecting and conveying chips of the machine tool, for example.

This granular material conveying device has a straight spiral body arranged in a straight groove with a substantially semicircular cross section, and a power source is connected to the end of the spiral body. A chip is dropped into a groove, the spiral body is rotated within the groove, and the chip inside the groove is conveyed in the axial direction by the spiral movement.One spiral body is driven by one drive source. It was driven and linear.

``Problems that the invention aims to solve'' However, with the recent progress in unmanned transportation and systemization, such conventional powder and granular material conveyance devices are equipped with multiple machine tools, and the amount of waste discharged from each machine tool has increased. When trying to collect and centrally process chips, if the above-mentioned conventional conveyor is used to connect each machine tool and the central conveyor, the flow of chips must be straight-lined each time the flow of chips branches, bends, or merges. Conveying devices had to be arranged, wiring to each drive source was complicated, and the connection structure at branch points, etc. had to be devised, which caused problems, especially when centrally managing powder and granular materials. . Furthermore, since each device has its own drive source, power is wasted, which is problematic in terms of cost and energy conservation.

The present invention was developed by focusing on such conventional problems, and it is possible to avoid branching, bending, and bending of the flow of chips.
It is an object of the present invention to provide a conveying device for powder and granular material that can easily handle merging and can solve the above-mentioned problems by requiring a small number of driving sources.

``Means for Solving the Problems'' The gist of the present invention for achieving the above purpose is to rotate spirals arranged in series within a groove or cylinder with a substantially semicircular cross section to form a groove within the groove. A conveying device for conveying powder and granular materials includes a first spiral body having the drive source at one end, and a second spiral body disposed opposite to the first spiral body.
a spiral body; a universal joint that connects the first spiral body and the second spiral body; and a discharge port provided on the lower side of the universal joint; The present invention resides in a powder or granular material conveying device characterized in that the powder or granular material is carried out toward a central universal joint and discharged from a central discharge port.

"Function" Therefore, it is possible to connect a plurality of spiral bodies via a joint, thereby arranging the plurality of spiral bodies at an angle so that the powder or granular material can be conveyed in an appropriate direction, and 1 spiral body
It is designed so that it can be driven by a local drive source.
