Description

The invention relates to automatic weights consisting of a rocker arm, on one shoulder of which a weight box is suspended, and an external-rotating drum, equipped with partitions And a disk with cutouts located along the periphery of the latter, which serve to rest the rotation of the drum pins. .

The proposed automatic scales for bulk and liquid materials are equipped with two electromagnets, one of which is used to hold the loading rocking tube, which serves as the main electromagnet, in the direction of the weighed substance into the drum, until the equilibrium begins, when the second electromagnet that acts from disk cuts lever, spring brake.

The drawing shows a view of the automatic scales in front.

Dental scales for weighing loose and liquid substances / consist of rocker arms, on the short arm of which a rotating drum is fixed, equipped with internal baffles - and a disk 15, with cutouts along the periphery of the latter, against which the pin of the lever 14 connected with the spring abuts 8, brake wheel drum rotation. To fill one

from the sections of the drum, the pumping tube 1, is a weighed substance, pulled by the spring 2 and being; korem for the electromagnet 3, included in the circuit 5, 4, 7, 6.

In the position of directing the substance to be weighed into the drum, the tube 1 is held by an electromagnet until the rocker reaches a horizontal position, i.e. until the balance is in balance. At this moment, at the right end of the yoke, the circuit 10, 11, 12, 13 closes with the contact 16 on the balance beam of the second electromagnet 9, which pulls the lever 14, as a result of which the circuit of the first electromagnet 3 opens and the loading tube 1 is pulled away by the spring 2 to the side. At the same time, the drum rotates, accompanied by the unloading of suspended material from the section, until the pin of the lever 14 gets into the next disk cutout, and the circuit of the first electromagnet 3 is closed again; then the cycle is repeated again.

The subject matter of the invention.

An automatic scale consisting of a rocker, on one shoulder of which a cup for weights is suspended; and on the other there is a rotating drum, equipped with partitions and a disk with cutouts located on the periphery of the latter, which serve to stop the rotation of the drum brake pins, which are different in that a swinging pipe 1 was used to load the substance to be weighed into the drum 2 and the electromagnet 3 crust, chains 5, 4, 7, b, designed to hold up the balance of the said pipe in the position of the direction of the substance being weighed into the drum, until the spring is braking Noah lever 14 from the cut-outs of the disk 15 applied electromagnet 9 of the circuit 10, 11, 12, 13 with pin 16 on the rocker arm.
