SU96023A1 - Automatic Scales - Google Patents

Description

This invention relates to automatic weights for small lump materials, mainly ravioli, with onion throwing and turning, and automatic electric control from the hammer: weight tool.

The proposed automatic scales, in comparison with the known weight of a similar design, allow for a more accurate loading of a small piece of material on the rotating orbital bucket and are different in that different doses of the drum are used.

FIG. 1 shows a general view of the automatic scales; in fig. 2 - their plan view; in fig. 3 is a section along AA in FIG. one..

On the rack J of the balance, mounted on the weighing rod 2, a tilting swivel was mounted on the axle-carrying axes x 3 of the bucket 4} which was supported by the load 5.

To eliminate the arbitrary tipping of the bucket 4, a relay 6 is installed, on which on the; ore 7 there is a latch holding the bucket in an inclined position in which the lower opening of the bucket is closed by the frontal part 8 of the guiding descent 9.

The dumping bucket 4, filled for example with dumplings, is held in an inclined position until a current is applied to relay 6, with which the measles are attracted by the relay core and the latch with bark moves to the side, where the bucket 4 is tilted and , freeing from dumplings loaded into it, returns to its original position under the influence of the load 5.

For feeding into the bucket 4, weighing small-cube material, for example, ravioli, was used in the scales with a dose of 1 dose, the second dose of the drum 0, in which there are two pockets 11 for the main dose and ten pockets 12 for additional doses. Vrapdenne dosing

the drum 10 (translational step motion) is produced in the direction of the arrow A from the electromagnet 13 through the bridge 14 and the storage mechanism 15.

The INO pulse of the electromagnet and the I-1 13 enters through the relay 16 from the contact of the relay 6, which turns on at the time of the return of the holder 4 to the initial position, which is fixed by the latch.

Relay 16 is adjusted in this case to 1 inclusions of inclusions so that the metering drum 10, turning 180 °, poured the main and five additional doses into its ii atheral a;

As a pulse sensor on the relay, and on relay 16, there is a contact group 17 that is mounted on the dial of the scale and moved along 1 piece 18 on the desired scale. For more accurate shifting, adjusting screws 19 are used.

The arrow of the 20 scales, reached the lead 21 of the 1-contact group 17, closes the contacts 22 and supplies current to the relay.

Contact group 17 has three pairs of contacts, of which a pair of contacts 23 is closed while material is being fed into the bucket 4; the same contacts are opened simultaneously with the closure of the bunches of the cops 22 while the material is weighed and KOBHJ is already tilting.

A pair of contacts 24 controls the weighing accuracy. When the weight of the material is turned, the scale arrow advances beyond the established weight standard and closes the contacts 24, which terminate the signal indicating an overweight.

The weighed fine-couscous material enters from the hopper 25 into the metering drum 10. When the test drum 10 is rotated, the first dose is poured into the bucket 4, the main dose from the pocket 11, then the additional doses from the pockets 12. When the weight of the scale is sufficient, the switch turns on the contact, relay 6 triggers the bucket 4 is tilted, and the dosing drum 10 continues to be hostile until the sixth switching on of relay 6, throwing additional doses of material on the tilting head, who is 26, from which the material is poured back into the bunker 25. Tipping disc 26 and turn the rim of the bucket 4 last stavits in one or the other of: 1ozhenie n maternal or falls into the bucket 4 or back into the hopper 25.

As a contactless relay in the scales can be applied photocell, EOS n1, EU of photo cells 27 and the backlight lamp 28, the substitute on the arrow of the scale and the slit 29 for the shifted lens 30 on the basis of the beam.

Subject and purpose of this

In the case of automatic scales for small-sized materials, mainly for dumplings, equipped with a tilting swivel bucket and an automatic one; m electrically controlled from the weight gauge, so that possibly more accurate loading of the bucket with fine lumps of material is attached to them; dose drum.
