Abstract

(57) [Summary] [Purpose] It is possible to pull round-shaped chips, etc., which are difficult to accommodate in the trough, into the trough by hooking the curled part with the notch. Transport to the designated disposal site can be carried out smoothly. [Structure] Notches are formed from the peripheral edge of the blade of the screw in the direction of the rotation axis, and the notches are arranged at appropriate intervals on the peripheral edge of the blade.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is designed to transport cutting fluid, chips, etc. discharged during machining by machine tools. This relates to a screw conveyor installed in

0002

[Conventional technology]

The screw conveyor conventionally used in machine tools, etc. is shown in Figure 4. As shown in FIG. It is configured by arranging a 1-axis is accommodated in the trough 10, and the screw shaft is arranged by rotating the screw shaft 1. It is pushed in the specified direction and transported to a predetermined disposal location.

0003 When processing with machine tools, cutting machines, etc., the material of the workpiece, cutting speed, etc. Therefore, the current situation is that chips of various shapes are discharged.

0004

[Problem that the idea aims to solve]

For this reason, for example, when turning a workpiece made of highly viscous material, , chips are often discharged in the form of continuous dumplings and are stored inside the conveyor. This type of dango-shaped chips are splashed on the spot by the rotation of the blades of the screw shaft. It may be impossible to transport the waste to the designated disposal site, or it may be There was a problem that it took too much time to transport.

[0005] This invention was made under the above circumstances, and its purpose is What kind of chip shape can be determined by changing the shape of part of the screw shaft vane? A screw conveyor that allows smooth transportation to the designated disposal location even if the The aim is to provide the following.

[0006]

[Means to solve the problem] In order to achieve the above objectives, the present invention forms spiral-shaped vanes in the trough. In a screw conveyor in which a screw shaft is arranged, the circumferential edge of the blade is A notch is formed from the edge in the direction of the rotation axis, and the notch is inserted into the blade at appropriate intervals. This constitutes a screw conveyor characterized in that it is disposed on the peripheral edge.

[0007]

[Effect]

With the above configuration, continuous bump-shaped chips from machine tools, etc. When the chips are discharged and fall into the conveyor, some of them get caught in the notches formed in the blades. It hangs and rotates, and the entire chip is caught in the trough and does not jump up on the screw. It is transported without a trace. In addition, since the notches are formed at appropriate intervals on the peripheral edge of the blade, Fine chips and other particles do not accumulate in the trough, which would otherwise be a hindrance to conveyance. There's nothing to do.

[0008]

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3. In addition, In this embodiment, parts that have the same structure as the conventional structure shown in FIG. The explanation will be omitted.

[0009] FIG. 1 shows an embodiment of the present invention, in which the peripheral end of a blade 1a of a screw shaft 1 is shown. A V-shaped notch 2 is formed from the edge in the direction of the rotation axis, and the notch 2 is spaced appropriately. Thus, it is arranged along the spiral of the peripheral edge of the blade 1a.

0010 The notch 2 is cut into the bottom of the trough by appropriately setting the degree of cut (depth). 10a is set to such an extent that fine chips do not remain, and the spacing between them is also similar to that of the blade. It is set according to the pitch, and if it is set in several places within one pitch of the blade, Even fine chips do not interfere with conveyance.

[0011] As a result, the chips D discharged from the machine tool, especially continuously as shown in Fig. If there are chips that are shaped like bumps, place them in the notch 2 of the rotating blade 1a. The curled part will get caught and the entire chip will be rolled into the trough 10. Ru.

0012 Therefore, the dango-shaped chips D that have fallen into the trough 10 are bounced up on the spot. It is transported in the same way as other shapes of chips d without being blown away.

[0013] FIG. 3 shows another embodiment of the notch 2 formed in the blade 1a. The cutout 2 is formed into a rectangular shape. The arrangement spacing etc. are the same as in the above embodiment. Yes, in short, the shape is designed so that the dango-shaped chips D etc. can easily be caught on the edge of the notch. It's about getting there.

[0014]

[Effect of the idea]

As explained above, according to the present invention, from the peripheral edge of the screw blade to the rotation axis. A notch is formed in the direction, and the notch is arranged at appropriate intervals on the peripheral edge of the blade. As a result, not only fine chips but also chips jump up on the spot when conveyed. Even easily-dango-shaped chips can be caught by the curled part by the notch and pulled into the trough. Regardless of the shape of the chips, they can be smoothly disposed of at the designated disposal location. The conveyance is done by It is.

FIG. 2 is an explanatory diagram showing an example of chips discharged in the shape of a lump.

FIG. 3 is an explanatory diagram showing another embodiment of the notch according to the present invention.

FIG. 4 is an explanatory diagram showing a conventional screw conveyor.
