SU26817A1 - Automatic scales for weighing liquids - Google Patents

Description

The invention relates to automatic weights, for weighing liquids, at one end of the rocker arm of which a rotating drum is suspended on a horizontal axis and provided with partitions.

In the proposed automatic scales, a swinging tube with a swing axis eccentric with respect to its center of gravity is used. This axis serves to hold, until the balance is in balance, in the open position of the two valves supported by their rods against the stop located on the swing axis. For turning the drain pipe, corresponding to the closing of one of the valves, a device was used consisting of a triple lever, one arm of which is intended to be hooked onto the earring rollers.

In a modification of the invention, instead of valves, a hinge tube connected to the weight of the weights and equipped with a drainage tube controlled by a weight mounted on the balance beam was used to drain the required portion of liquid from the filling tank.

In FIG. 1 depicts a general view of the scales; - a perspective view of the corjTacHtoi tank, modified. the shadows .. i.i.i.

Offered Automatic Scales

for weighing the fluid, the weights were built for loose bodies, but instead of a hopper with valves for the flow of loose materials, a drain pipe 7 (Fig. 1) was used with a swing axis eccentric with respect to its center of gravity, which simultaneously it stops, until the balance is in balance, in the open position with valves 5 and 6 of different diameters supported by their rods against the stop. For turning the drain pipe 7 is a device consisting of a triple arm 12, 11, 10, the shoulder 12 of which is intended to engage the roller 26 of the earring 4, together with the arm 11, to control the rotation of the pipe 7 corresponding to closing the valve b larger diameter). The shoulder 10, which is held back by the latch 9, is controlled by the rotation of the drain pipe 7, which corresponds to the closing of the valve 5 (of smaller diameter).

Instead of a hopper used in bulk solids scales, there is a liquid tank 1, at the bottom of which the valves 5 and 6 are placed.

Under the bunker, on the axis 19 passing through the shackle 4, a drum with a bucket 18 is placed, which is intended to enter into it, weighed out:

ekidkosti, then poured into the funnel 24.

 running up the earrings 4, turning with a naked weight 23 equal-arm rocker, roller 25 lifts the dog 12; Thus, the dog 11, sitting with the dog 12 on the common axis 13 (Fig. 1), lifts the drain pipe 7, which, in turn, extends upward the valves 5 IB. .The fluid through the two valves immediately through the drain pipe 7 enters the bucket 18, By balancing the rocker arm kla. The pan b is closed, and through the valve 5 the fluid is added to the exact plumb, after which the roller 8 of the station 4 presses the latch 9 and the drain pipe 7 finally, the topping valve 5 closes down by this movement.

Now, after this, the latch 15 comes out of the socket 16 of the ring 27 and the bucket 18, tilting, through the funnel 24, pours the liquid into the dishes of the customer.

According to a modification of the invention, in order to drain the required portion of liquid from a tank of 1 hour (Fig. 2), instead of valves 5 and b (Fig. 1), a hinge tube 2, which is connected with its upper end to a liquid in tank 1 (Fig. 2), is connected with the help of ti gi 3, yoke 4, ti gi 9 with a clamp 15 weights. The marked tube is provided at its outlet with a slush tube 106, 10c, controlled by a roller ch11, mounted on the balance beam balance lever. When weights are mounted on a certain weight, the clip 15 of the earrings rests on the pull 9, lifts it and immerses the tube 2 into the liquid, which immediately through the tube enters the drain tube, which is at that time in the 10c position. Fluid from it flows into the weighing bucket. As soon as the desired plummet is obtained, ha ha 9, thanks to the counterweight B, goes down. The inflow of fluid into the drain pipe also stops, thanks to a roller 11 attached to the rocker arm: weight, it takes position 106, picking up 3 excess liquid that has not had time to leave the drubka and stop simultaneously the fluid flow into the weight bucket.

In order to achieve an accurate plumb, the tube 2 is provided with a slit 12 through which fluid is added to the exact plummet. Screws b and 7 frames 5 limit the movement of the rocker arm 4, as a result of which, after being weighed, the feeding mechanism is disconnected from the weighing device.

The subject matter of the invention.
