Description

[Detailed description of the invention] [Technical field] The present invention provides a deformed material supplying device having a rectangular parallelepiped shape;
In particular, the present invention relates to a technique that is effective when applied to supplying a rectangular parallelepiped shaped material to a processing section of a machine tool.

[Background Art] Generally, materials processed by machine tools, such as NC lathes, are sometimes supplied in the form of round bars. In this case, since the round bar has a circular cross-sectional shape, there is no problem in clamping, inserting, etc. in a collet etc., regardless of the feeding orientation.

However, when supplying irregularly shaped materials having a rectangular parallelepiped shape, it is not possible to properly clamp the material with a chuck or insert it into the collet of the processing machine unless the material is supplied in a predetermined orientation. There are problems such as the need to insert one tube at a time, making it impossible to automate the device.

Further, as another profiled material supplying device, there is one described, for example, in Japanese Patent Application Laid-Open No. 51-62488.

In other words, other shaped material supply devices supply a right-angled rod-shaped body having at least one angular surface on a part of the lengthwise direction of a round bar-shaped body, and feed the shaped material sequentially and intermittently along the supply path. A roller system in which a rod-like body with an angular surface, which is fed by a wafer, is pressed from above by rolling friction using a spring-loaded pressure roller to hold the angular surface in a horizontal position, or an elastic deformation method. This slider is brought into sliding contact with the upper corner surface of the rod-shaped body at a predetermined height position on the supply path, and the pressing force generates a moment on the rod-shaped body to maintain the corner surface in a horizontal position. It has a slider type structure.

However, in both the roller method and the slider method described above, a round bar-shaped body having at least one angular surface on a part of its longitudinal direction is the object of supply of the shaped material. Since the structure is such that the rod-like body rotates and maintains its posture through rolling or sliding contact with a corner surface, there is a problem in that it is possible to maintain the posture of a rectangular shaped member. .

[Purpose of invention]

The present invention has been developed by focusing on the above-mentioned problems, and its purpose is to supply a shaped material that can easily maintain the posture of a shaped material having a rectangular parallelepiped shape and automate the feeding of the shaped material. The goal is to provide equipment.

It is sent into the interior from above in the lateral direction.

The deformed material W supplied into the guide 6 is moved by a drive motor 25 to a pair of pushers 28 of the auxiliary posture control section 14 and a pair of pinions 26 and a pair of racks 27.
By moving them closer to each other via , the irregularly shaped material W in a vertically long position can be adjusted to a desired horizontally long position.

The profiled material W whose posture has been controlled is fed by a feeding bar 9,
It is moved forward within the guide 6 by the feed bar drive device 10, and the tip is fed into the posture control holding section 34 of the delivery mechanism 3. In the posture control holding section 34, air cylinders 38 and 39 are used to control the heads 40 and 41.
By driving the two heads 40 and 41 vertically close to each other, the profile W is moved from above and below into both heads 40 and 41.
The device is held in the desired posture between the opposing surfaces of the device.
Then, the posture control holding section 34 horizontally moves in the direction of the processing machine 2 by the feed bar 9 and the feed bar drive device 10 while holding the irregularly shaped material W.

Thereby, the tip of the profiled material W is smoothly fed into the chuck portion 45 of the main shaft inner tube 43 of the processing machine 2. In this case, since the dimensions and opening direction of the chuck portion 45 of the main shaft inner tube 43 correspond to the dimensions and feeding attitude of the deformed material W, the deformed material W can be inserted into the chuck portion 45 extremely smoothly.

The profiled material W thus supplied into the processing machine 2 is subjected to predetermined processing such as cutting and cutting in a processing section within the processing machine 2.
