Description

To clarify and speed up bulk weighing; goods in retail offers a device of weights, in which the termination of filling containers with a given product weight occurs under the influence of a current closure in a circuit including electromagnets by force of force, releasing spring dampers, designed to cut off the flow of loose goods into the container installed on the weighing pan and secured in the open position by the action of a hand lever.

In FIG. 1 is a front view of the device; FIG. 2 is the same side view; FIG. 3 — electric current switching circuit; FIG. 4-piece device bottom bucket.

The proposed device is a coaxial pump from a distribution box I installed above one of the scales cups, at the bottom of which bucket there are two openings, a large 3 and a smaller 4, which are closed by dampers. 5 and 6, which are under the squeezing action of the coil springs and which are discharged to the side for opening the openings 3 and 4 by the action of the handle 9 through the cables. To hold the dampers 5 and 6 in the open position, latch 7 and 7, opened by electromagnets 10 and 11, equipped with relays 15 and 16 are used. For closing the circuit, contact needles 17, 18 and 19, connected to the weighing pan, loaded with the weighed goods, needle 19 serves only for supplying current to two other needles; spring electrodes 12 and 13 serve to open the electromagnets circuit, and the same circuit breakers 23 and 23t serve for the relay circuit, and contacts 12 and 13 are brought into contact with fixed contacts by the action on them by the lever 14 and 14 movable fingers fixed on flaps 5 and 6. The breaker 18 comes into contact with the mercury filled Yusch

a vessel whose volume is adjusted by pressing the screw 21 through the plate 20 onto a rubber hose in communication with the vessel, and on the other weight weir the spring 24 serves to dampen the oscillation of the weights under the pressure of a stream of bulk goods. Pointer 22 indicates the height of the mercury level under the needle 18, and pointer 25 regulates the resistance of the spring 24.

Upon opening both dampers by hand movement of the handle 9, the bulk product fills the container placed on the scale weights, and when lowering this cup, the needle 17 first comes in contact with the mercury and turns on the relay 15 and the electromagnet 10, 5 and causes the damper 5 to close, cutting off a wider opening 3, and then as the weighing pan is further lowered and equilibrated with the cup, behind: a loaded weight, contact 18 is connected and the pin of the relay 16 and electromagnet II attracting the flap 7 and closing the second hole 4. Pru pin contacts 12 and 13

when opening, the action of mercury contacts is ahead and, thus, eliminate / damage these latter from arcing when current is opened.

PROPOSAL SECTION.

A weighing device, loose goods, characterized by the use of two flaps 5 and b above openings 3 and 4 in the bottom of the bucket I, for opening of which flaps, under the action of squeezing and spiral springs, serves as a knob 9, connected with cables flaps, and for holding them in the open position, latches 7.7i are arranged, opened by electromagnets 10 ,, 11, equipped with relays 15, 1o for closing the circuit of which contact needles 17, 18, 19, attached to the weights, serve. And for smithing the circuits of both relays and electromagnets 10, 11, breakers 12, 13, 23, 23i were used, the controllers. my valves 5 and 6 through the levers 14, 14 ,.
