The portal frame 11 is moved forward and backward relative to the material block M by rotating the traveling motor 12 in forward and reverse directions.

Screw shafts 19 and 19 are erected at the front and rear of both sides of this portal frame 11, respectively, and a driven sprocket 20 fixed to the upper end of the screw shaft 19 includes an idler sprocket 21, a chain 22,
It is connected to a drive sprocket 23 of a lifting motor 24 provided on one side of the upper part of the gate-shaped frame 11.

Nuts 27 provided at both ends of the beam 26 are screwed into the screw shaft 19, and the beams 26 and 26 are raised and lowered by rotating the lifting motor 24 forward and backward. A pivot 28 is suspended from the beam 26, a horizontal frame 29 is pivotally attached to the pivot 28.28, and the horizontal frame 29 and the beam 26 constitute an elevating frame 25.

The elevating frame 25 is provided with a spike truss, generally designated by the reference numeral 30, which is driven by a fiber opening motor 31 and whose lower surface forms a scraping surface that operates horizontally toward the side conveyor 6. Since it belongs to known technology, it will not be described in detail.

Further, a tilt cylinder 32 is pivotally attached to the beam 26,
The lower end of the actuating rod 33 is pivotally attached to the side of the horizontal frame 29. Therefore, by expanding and contracting the tilt cylinder 32, the lower surface of the horizontal frame 29, ie, the spike trusses 30, is tilted rearward with respect to the advancing direction of the portal frame 11.

In FIGS. 5 to 7, guide rails 34.34 are provided projecting from the front and rear of the horizontal frame 29 in the direction of movement, and a gate-shaped frame 35 supports wheels 36.36 on the guide rails 34.34. A guide roller 37 is provided between the lower ends of the frame 35 in parallel with the rail 4.5. A rod 39 is pivotally connected to the lower part of the frame 35 via a bracket 38, and the rod 39 is pivotally supported by an arm 40 fixed to one end of a shaft 41 that is pivotally supported by the horizontal frame 29. ing. A driven sprocket 42 is fixed to the other end of the shaft 41, and the sprocket 42 is connected to an idler sprocket 44 by a chain 43.
It is connected to the drive sprocket 45 of the reduction gear 46 via.

The driven pulley 47 of the reduction gear 11146 is connected via a belt 48 to the drive pulley 49 of the guide roller motor 5°.

4 to raise the elevating frame 25, operate the tilt cylinder 32 to tilt the portal frame 11 backward with respect to the traveling direction, and position the spike trusses 30 at the position (3) shown in FIG. The guide roller motor 50 is operated to bring the guide roller 37 to the position shown in FIG. 5, for example, so that it comes into contact with the side surface of the material mass M1 (FIG. 3).Next, the opening motor 31 is rotated in the normal direction to create a spike. The lower surface of the trusses 30 is operated to the left in FIG. 3, and at the same time, the traveling motor 12 is rotated forward to move the portal frame 11 forward (to the left in FIGS. 1 and 4) to open the fibers. The spread fibers are conveyed to the side conveyor 6.

During fiber opening, the guide roller 37 prevents the material lump M1 from being scratched by the lattice 30 and falling in the fiber opening direction, that is, toward the side conveyor 6 side. Further, the backward tilt of the lattice 30 allows for smooth advancement while opening the fibers. In this way, by sequentially and continuously opening the plurality of material lumps M1 from the upper surface downward, the opening efficiency can be greatly improved compared to the conventional apparatus.
