Description

The proposed device is intended to account for and control a weighed product or material passed through an automatic balance, and can be used in elevators, mills, bakeries, etc.

The device consists of a conventional type of meter with an electric drive and an instrument weights for sending current to the meter. The latter is made in the form of an additional weight lever between the platform and the loading bucket. The lever serves to control the contacts in the electric drive of the meter.

In FIG. 1 is a front view of the device; FIG. 2 is a view along arrow L in FIG. one; . 3 - front view of the counter; FIG. 4th vertical section.

A conventional type of counter (Figures 3 - 4) consists of digital wheels interacting with a ratchet wheel, rotated by a pawl 3, attached to the electromagnet cortex 2 /, the current in the circuit of which is closed by a device installed at the scales.

In a nov / 2 scale for a material to be weighed, usually resting on a weighing platform acting on the main frame arm to enable automatic sending of current

The counter is separated from the weighing platform / 5 and is mounted, on the one hand, on fixed supports, and on the other hand, is supported by its knife 5 on the additional weight lever 6 (Fig. 1) between the bucket and the weighing platform. The lever 6 rests on the knife 4. mounted on the frame / 3, and provided at the end with pins //, serving to supply the JO contact spring fixed in block 7 to the adjusting screw of pin 8 to close the current in the counter circuit. The lever 6 is loaded with a balancing spring 9.

When the forging lever is loaded, the lever 6 will act on the spring 9, lower the upper pin / 7 and press on the contact spring JO, which is ejected by the lever and bent towards the contact screw 8, turning on the current in the meter circuit.

After the bucket is emptied, spring 9 will lift lever b, which will lower contact spring 0 to its original position with lower pin / 7, opening the electric circuit of the counter, and the process repeats again.

The weights themselves are suspended from the main frame through the hundredth levers, and in the proposed device the bucket / 2 is suspended to the weighing platform 75, as a result of which weights on the scales are obtained.

This arrangement of the device ensures the operation of the meter, independent of the movement of the scales, and eliminates the influence of the device on the number and accuracy of the scales.

The subject matter of the invention.

A device for counting the number of suspensions produced on automatic scales,

wherein an electric actuator is used to actuate the meter, characterized by the use of an additional weight lever 6 installed between the weighing platform and the bucket for the material to be weighed and used to control the electrical contacts in the electric drive circuit of the meter.
