Description

The present invention is intended to substitute manual labor for cutting mid-section treads from a rubber sheet.

In the schematic drawing of FIG. 1 is a side view of the machine; FIG. 2 is a view from above; FIG. 3- in front; FIG. 4 is a top view of the template and FIG. 5-slit it in D E p & FIG. four.

The machine consists of an endless conveyor chain 1, carrying on its links platforms 2 that are stably supported to them, on which, in turn, are metal (steel) figured patterns 3 of known height with sharp edges (Fig. 1, 2, 4 and five). Platforms 2, at their ends, enter tides 23, located on a certain section of the machine frame and equipped with balls, the purpose of which is to reduce the friction between tides and the ends of the platforms. The tides 23 give a strictly stable, horizontal position to the platforms 2 and, therefore, to the templates 3, when the latter begin to enter under the roller 4 and experience its pressure. When the conveyor is moving forward, the templates 3 fall under the roller 4 and the rubber web located on them, the pressure of the roller cuts and is cut out in the form of templates. In addition, the tides serve for platforms 2 during the pressing of the rollers 4 on the templates 3, because otherwise the conveyor without appropriate supports would disturb the stability of the platforms with templates on it and thus prevent the rubber sheet from completely cutting.

Inside each template 3 there is an insert 24 (Fig. 4 and 5), in a shape similar to the templates, but smaller in size. Said inserts are advanced from patterns 3 by rods 25, which are fastened in inserts by screwing. The rods 25 pass through the corresponding holes in the platforms 2 and end with balls 26, which rotate freely in the special holders 28. In front of the holder there is a disk 29, between which and the platform is inserted a spring 30 (Figs. 1 and 5). The inserts 24 are inside the templates if their rods 25 are not on the plane 27 (Fig. 1). This plane is a curve at the beginning, then it is horizontal and located inside the machine at some distance from the conveyor. The rods 25, falling at their ends - balls on the curved end of the plane 27, move freely along it.

At the same time, as the rods move along the horizontal part of the plane, the springs 30 are compressed and push the inserts 24 of the templates 3 together with the shaped pieces of the rubber web inside it.

The conveyor movement is carried out by the working pulley 8, on the shaft 9 of which the chain gears 10 and 11 are mounted. The latter drives the gear 12, on the shaft 13 of which there is a large gear 14. The gear 14 engages the gear 15 on the shaft 16 with a roller mounted on it 4 rotating in bearings 19 enclosed in rails 20. On the shaft 16 there is a gear 17, which serves to transmit the rotation gear 18, on the shaft of which a roller b is mounted, which serves to clean the openings in the drawer 7. The roller 4 moves up and down with the help of a worm 22, on the top end of which is mounted the knob 21 (FIGS. 1, 2 and 3).

The rubber canvas 5 at one end of the machine is superimposed on the sharp curved patterns 3 of the conveyor, moves with it and falls under the roller 4; This roller, rotating at a speed equal to the speed of the conveyor, with a known force, presses onto the canvas, cuts it and cuts it according to the forms of the templates.

The figured parts cut out of the rubber sheet remain (due to their own weight) inside the templates, from where they are pushed out by the inserts 24, and the openwork (tightly without cut parts) goes further through the roller into box 7, cleaned as necessary.

The subject of the patent.

1. A machine for cutting cutting material and other material, using chain 1, the links of which are equipped with platforms 2 with figured templates 3 supported on their ends, with the aim of eliminating their bending, on frame tides 23, and for pressing on a rubber canvas lying on the sharp edges of the templates, the roller 4 is applied.

2. In the machine described in paragraph 1, the use of figured patterns 3 (Fig. 5) provided inside with an insert 24, in a shape similar to a template, with a rod and with a spring 25 (Fig. 5) passing through the platform and ending with a ball 26, enclosed in the cage and designed to push the insert 24 out of the template 3 and to throw out the cut out styles by rolling the ball 26 along the horizontal and then curved surfaces.
