CHIP DIRECTOR - RIKTARE FÖR SPÄNOR

The present invention relates to a chip rectifier for a scattering line, which chip rectifier consists of disintegrating scattering rollers in which the chip stream is dissipated to an underlying alignment unit. axial radial wing structures in which the chips are oriented.

For example, U.S. Patent 4,388,055 discloses such a rectifier. U.S. Patents 4,058,201 and 3,896,536 also disclose so-called transverse deflectors in which the chips are positioned transverse to the scattering line with respect to the direction of travel. The object of the invention is to provide a new type of simple and inexpensive and reliable chip guide.

The rectifier according to the invention is characterized in that the wing structures are wedge-shaped structures widening in cross-section from the tips to the axis. By means of the invention, all the chips passing through the guide are made parallel to the spreading conveyor below, especially when wedge-like spaces are obtained between the wing structures of the guide member and the jacket plate, in which the orientation of the chips increases.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which

Figure 1 shows the main parts of the chip rectifier seen obliquely from above.

Figure 2 shows an end view of an orienting member according to an embodiment.

Chip rectifier for a scattering line, which chip rectifier consists of disintegrating scattering rollers 1, in which the chip stream is dissipated to a lowering orientation unit 2, where the chips are directed and settled on the lowering conveyor 3 in the desired direction. The orientation unit 2 consists of a plurality of adjacent orienting members rotating about its axis 4. The orienting members consist of axially radial wing structures 5 fixed to their shaft 4, in which the chips are oriented. Between the orienting members there are casing plates 6 partially surrounding the orienting members. The wing structures 5 are wedge-shaped structures widening in cross-section from the tips to the shaft 2. The elongate chips settle in the wedge-shaped gaps 7, orienting in the desired direction to a small extent in the first stage. At the latest in step 8, the chips slide along the "steepened" side 9 into the wedge formed by the jacket surface 10 and the sliding surface 9 and the orientation increases. In step 11, the chips momentarily stop on the jacket surface and the wing structure side 12 pushes the chips further, eventually dropping them from the jacket surface to the spreading conveyor 3 below. The chips fall from point 13 in a small group, with almost no mixing during free fall because the chips support each other.

It will be apparent to those skilled in the art that the invention is not limited to the examples set forth above but may vary within the scope of the claims set forth below. Thus, the spreading conveyor can also be horizontally inverted partially or even at an angle of 90 ° to the orienting members above, thus obtaining a chip rectifier in which the chips are placed on the spreading conveyor obliquely or even longitudinally.
