An elegant roofing shing machine that includes a frame, a drive disk with knives, bunkers for laying finished products located under the disk, clamping mechanisms for installing the workpiece and the fixture of the finished product placed under the disk does not ensure its good quality.

The purpose of the invention is to improve the quality of manufactured products.

This is achieved by the fact that on the disk shaft there is a cage mounted with cams, which interacts with a retainer made in the form of a rocker arm pivotally connected to the frame with an emphasis, and the clamping mechanisms are provided with guides with the cassettes securing the workpiece.

FIG. 1 shows a machine, longitudinal section; in fig. 2 - the same, top view; in fig. 3 - cassette, general view; in fig. 4 - cutting elements.

The machine contains a rectangular frame 1, to which the squares 2 are welded to the stability of the machine. A gearbox 3 with a vertical shaft 4 is mounted to the bottom of the frame 1, the ends of which rotate on the bearings 5. A flange 6 is mounted on the splines of the shaft 4, to which is attached a disk 7 with knives 8 radially arranged in it with bolts and nuts, welded to the bottom of the drive.

Adjusting bolts 10 are screwed into strips 9 and bolts 11 with nuts are inserted for fastening knives 8 of stop 12, shells 13. The clamping bars are welded to frame 1 and shells 13

the mechanisms 14 with the front 15 and with the rear 16 guides in which the cassettes 17 are placed. Under the disk 7, bins 18 are attached to the shells 13, gearbox bushings 19, cuff 20, cam ring 21, which is locked in position on the shaft 4 by the rocker arm 22, one end is pivotally connected to frame 1, and the other to roller 23 interacting with cam sleeve 21. A stop 24 is welded to the beam 22, guides 25 are welded to the gearbox 3, between which the beam 22 is placed. On top of the machine, the moving parts are covered with covers 26 ( on the other hand the lid is not shown but).

The rotors 27 cover the moving parts of the gearbox, pulleys and belts, an electric motor 28. The cassette 17 consists of a fixed comb 29 and a movable comb 30 placed in a U-shaped housing on a hinge 31. The comb 29 is fastened to the housing 29 from the top by a tube in which the spring 32 is placed, interacting with the comb 30. From below, the comb 29 with the stops 33 and the body at an angle of cut are connected by the bar 34. Cutting elements — the cutters 35 are fixed tightly into the threaded joints 36, which are screwed into the threaded holes 37 in the disc 7 and from the bottom up with nuts.

Works machine as follows.

The included electric motor 28 through a belt drive and a gearbox 3 drives the vertical shaft 4 to rotate on which the blade 7 with the blades 8 is mounted. The cartridge 17 is fixed with a stationary comb 29 onto the workpiece with a compressed spring handle 32. The mobile comb 30 firmly fixes the workpiece in it at a certain cut angle . The blank cartridge 17 is placed in the guides 15 and 16, the shingles 38 are cut with a thin disk 10 mm thick and the knives 8 are bent 8. The shingles 38 are partially cut down by an angle from under the disk 7, and the stop 12 with a rubberized top inclined towards rotation, touching the disk 7 does not allow it to fall outside the hopper 18. As the workpiece is cut, the cartridge 17 goes deeper to the lugs 33, the rest of the workpiece remains always the same. By pressing the lever of the movable comb 30, the rest - the humpback itself drops out, after which the work cycle is repeated. The cut plaster shing is fixed on the yoke 22 by the stop 24, which at the end of the cut shingles enters the tapered notch of the disk 7 and the blade of the knife 8. The ascent into the slot is done through the roller 23 and the cam holder 21. The end of the rocker arm 22 is placed between the guides 25. Thus by way of production, both roofing and plastered shingles, stacked in bunches 18 located under the disk 7.

To produce wood packaging chips and chips for fiber cement insulation boards, the stops 12, rockers 22 and hoppers 18 are removed from the machine. On the disk 7 in front of the cutting knives 8, threaded connections 36 with incisors 35 are screwed into the holes 37, which are separated from each other by the desired width shavings. They are set to the desired height, and the bottom is locked with a nut. The knives 8 are adjusted by adjusting bolts 10 to the desired chip thickness. The cut chips fall down and can go directly to the conveyor belt for subsequent operations.

The subject of the invention. A machine for the manufacture of roofing shingles, including a frame, a drive disk with knives, bunkers for laying finished products located under the disk, clamping mechanisms for setting the workpiece and a fixture of the finished product placed under the disk, characterized in that products, on the shaft of the disk is mounted a cage with cams, interacting in the process of working with a lock, made in the form of a hinged arm connected to the frame of the rocker arm with an emphasis, and the clamping mech nisms are provided to guide the cassettes, fixing the workpiece.
