SU13319A1 - Adaptation to the scraper conveyor for automatic feeding of the transported blanks to the place of their processing during the continuous method of work - Google Patents

Description

The invention relates to devices for accepting blanks carried by a scraper conveyor, the cholot of which is provided with a number of flap valves. C) the average travel speeds used on such conveyors lead to the fact that individual workers lose some time waiting for work, while others do not keep up with the pace of work of the transnrter, which leads to haste in work and consequently, deterioration and congestion. In order to eliminate this drawback in the proposed device, the flap valve is held in the closed position by the counterweight and opened under the influence of the weight of the workpiece to direct it along an inclined plane to the place of processing. To hold the valve in a closed position until the treatment is not taken from an inclined plane, the latter is arranged rotatable about the horizontal axis and provided with a adjustable counterweight sitting on the rod and horses; which is equipped with a hook, grabbing the end of the lever of the flap valve and thereby holding it in the closed position. In FIG. 1 shows a device with a closed flap valve; FIG. 2 - view from above; FIG. 3 -

device with an open flap; FIG. 4 - the same, with the valve closed, held in this position by the hook; FIG. 5 - the relative location of the conveyor and machine tools; FIG. 6 view of the conveyor from above; FIG. his side. The scraper conveyor chute is equipped with a series of hatches that are closed by flap valves 1 (Fig. 1-4), to each of which a lever 3 is attached with a counterweight 4, which holds valve 1 in a closed position. Under the valve 1, an inclined plane 5 is installed, rotating around the axis 6 and serving as a continuation of the inclined plane of the lowered valve 1. (2); A lever 7 is attached to the right side of this plane, equipped with a counterweight 8, which is mounted so that it tends to place the lever and the plane in a vertical position. This aspiration is prevented by the stop 9, which allows the lever 7 to lower only to a certain position, in which the hook A of the lever 7 will not interfere with the end of the lever S to rotate around the center 2 when the valve 1 is lowered by the weight of the workpiece. After the workpiece passes the surface of the valve 1 and lands on the plane 5 (Fig. 3), the valve 1. under the influence of the counterweight 4,

will take the initial position (fig. D), while the plane 5 will be in the position in: shown in fig. 3, in which the lever 7 rests on the support 9, which occurs until the workpiece, moving on the inclining plane 5, passes a point at which the counterweight 8 is balanced. After this, upon further movement of the workpiece, the lever 7 will rotate around center 6 until then; until hook A hooks at the end of lever 3 (figl 4).

- Thus, the lever 3, and the successor to, and the valve 1 will be closed. As soon as the worker removes the workpiece from the inclined plane 5, for performing any operation on it, the valve 1 is released, the fixture becomes in its original position. Under these conditions, I is working (He always has one blank on his hands, and the second on the plane b.

The subject of the patent. The adaptation to the scraper transiodter for the automatic feeding of transportable blanks to the place of their processing with the use of the working method, in which the chute is equipped with a number of flap valves, characterized by the fact that each flap valve 1 is kept in a closed position and has a closed flap. 4 and opens under the influence. the weight of the workpiece for directing the last / but inclined plane 5 to the place of processing, which is the plane, in order to keep the valve closed until the workpiece has been removed from it, is arranged rotatable about horizontal axis 6 and equipped with a counterweight 8 fixed on the rod 7, having on the end of the hook A, designed to grip the end of the lever 3 valve while rotating the plane 5 under the action of the weight of the workpiece. ,
