Description

The proposed machine for the manufacture of roofing shingles refers to woodworking machines, in which circular saws are used for cutting and cutting blanks, for planing and sampling grooves-rotating cutting chucks and for supplying blanks — endless chains with grippers. The proposed machine is also equipped with a series of devices directing the material into the sequential processing by various tools of the machine.

In the schematic drawing of FIG. 1 shows a general view of the machine from the side, and FIG. 2 through 5, guide devices in cross section.

On the table G of the machine there are two circular saws A vi B, chisels S and -G for sampling tongs and knives D for cutting the front side of the shingle, and under the table board on the left (according to the drawing) the end of the machine to the cartridge B is placed an infinite chain H s grabs. The guiding devices are located on the table in the following order, starting from the left: from the end of the table to the saw L - in the form of an E bracket open from one side (Fig. 2), then to the cutter cartridge G - in the form of a closed box 3 (Fig. 3 and 4), with cuts in the walls in places against machining cutting tools -B and P and planing knives D, and, finally, from cartridge G to

Saws B - in the form of a wider box E (Fig. 5), provided with wedge fist guides O.

A blank for shingles in the form of a bar or the like is inserted by the end into the open side of the bracket and advanced in it by the hooks of the endless chain H passing through the table cut to the saw L, where the rectangular piece M is cut off from the blank which already inside the box 3 to the chisel chuck I and to the planer knives D. Here, the chain action ends, to eliminate the reverse pushing out of the piece M of the workpiece, when the groove is dredged therein by the chisel chuck B, a spring latch L is arranged. The saw blade B is carried out by pushing it with the next blanks on the H chain. By chuck machining, the blank piece M enters the box L where the wedge fist guides O cause it to tilt (Fig. 5), and in such an oblique view the piece M is cut by saw B into two separate trapezoidal sections of the shingle plates.

The subject matter of the invention.

A machine for the manufacture of roofing shingles, using circular saws for cutting and cutting blanks, rotating cutting chucks for planing the blanks and sampling the spool; com and infinite chain with grips for; feed blanks, different application; neniem: for proper direction; the workpiece before the cut saw L (Fig. 1) - rigidly attached with a table | machine tool E (Fig. 2), for guiding the workpiece behind the saw A - box 3

(Fig. 3), to prevent the pre-pushing of the workpiece with the chuck B after it leaves the // chain - a spring latch L (Fig. 1) and to tilt the workpiece after it passes all the chuck sockets, in order to cut it with the saw B on the gontins, - boxes f (fig. 5) provided with wedge for preparation with cam O guides.
