Abstract

Electronic scales for determining the mass and cost of goods, containing a housing and a load receiving device associated with a vibration force transducer connected to the input of the measuring and measuring unit, the other inputs of which are connected to an operating mode block and a keypad for dialing numbers with magnetically controlled contacts, and the outputs are connected to a digital display panel showing the mass, price and value, as well as a power source and a base, characterized in that the dialing unit is made with a linear dial and a movable button relative to it th, designed to interact in the pressed state with magnetically controlled contacts of the corresponding number, and the force transducer is made with a rod to ensure interaction with the upper end with the bowl and the lower with the hook, while the base is removable.

Description

The utility model relates to electronic weighing equipment with a digital weight indicator.

Known electronic pocket scales containing a housing with a loading platform, mechanically connected with the counting unit, as well as a digital display / I /.

A disadvantage of the known scales is the impossibility of determining, along with the mass, the cost of the goods, as well as the inability to use them when weighing suspended goods.

Known electronic. Trade scales for determining the mass and cost of products, containing a housing and a load platform, mounted on a vibration force transducer connected to the input of the metering unit, the other inputs of which are connected to the operating mode block and key dialing unit with magnetically controlled contacts, and the inputs are connected with a digital display of mass, price and value, in addition to the power source and base.

These scales are used in the retail industry, but have not been used in domestic conditions due to a number of shortcomings, such as rather large dimensions and cost. The use of such scales is possible only in stationary mode.

The main task, which is directly addressed by H11oe (p | 1 |

is the creation of small-sized electric shyxria j:,. . Allowing you to weigh the goods, both with the help of: /;.: ППЕ of the receiving bowl, and with the help of a hook, moreover, it determines not only the mass, but also the cost on the digital indicator board.

Leah .. -

v- .Д - - IJ к This is achieved due to the fact that in electronic scales containing a housing and a load, there is another means associated with a vibrational force transducer connected to the input of the measuring unit, the other inputs of which are connected to operating modes and a keypad for dialing numbers magnetically controlled contacts, and the outputs are connected to a digital display of mass, price and value, as well as a power source and a base, the new one is the implementation of the keypad for dialing with a linear dial and a movable key relative to it Intended to interact pressed magnitnoupravlyaemymi contacts with the corresponding digit as well preobrazovatsh force formed with the rod providing the interaction with the cup ontsom upper and lower - with a hook, wherein the base is removable. This solution is illustrated by drawings, where FIG. 1 is a schematic diagram of a device, FIG. 2 is a general view, and FIG. 3 is a rear view. The device comprises a housing I, in which a vibration transducer of force id is installed, the rod of which is connected with the bowl with its upper end 4, and with the folding hook 5 with its lower end. Rod 3 is a prefabricated component. The force transducer 2 is connected to the counting unit b, the other inputs of which are connected to the operating mode unit 7, which includes the keys WEIGHT, PRICE, K1, K2, etc. , and a set of numbers 8, and the outputs are connected to digital displays indicating 9 masses, prices and costs. 3

opposite which the key stopped in the pressed state. A set of numbers is carried out in a given sequence. To ensure the operation of the device in calculator mode, keys with mathematical signs 1; are provided. To carry out weighing using the bowl 4, a removable base 13 is provided, which is installed on a horizontal surface, protected from vibration. For precise installation, there are three set screws 14 and a level (not shown). In Corus I, for mounting the bowl 4, a socket 15 is provided, Hook 5 is pivotally connected to the rod 3 of the transducer and in the idle position it is fixed flush in the back of the housing I, On the side surfaces of the housing

corrugated pads are fixed that prevent finger sliding when using weights in the manual version. A hinged bracket 17 is also fixed flush with the body on the back of the balance. The display 9 is made with 7-digit price and weight indicators and 12-bit - cost (calculator). To ensure the operation of the device there is a power source 18.

The balance works as follows,

Turn on the power source 18 and press one of the keys

WEIGHT or .. PRICE or KI or, On the base 13, the scales are installed in the guides (shown), and in the housing slot I

- bowl 4, When you press the WEIGHT key, the weight of the bowl is fixed on the display, to reset it, press the O key. The balance is filled with cargo. Under the influence of gravity on. the upper end of the power rod of the transducer (or a hook in the lower part of the rod) in the transducer 2 produces an electrical signal, the frequency of which depends on the mass of the load. The signal transmitted to the microprocessor of the counting measuring unit b is processed, and the result is the digital value of the mass is fixed on the display panel 9 of the mass display. To determine, along with the mass, the cost of the cargo, as well as when working in the calculator mode, it is used

set of carbs 8, in this case, prices. To do this, use the movable key II. When it moves along the dial 10, the value of the flange appears on the display panel of the price, opposite which the key is located in the pressed position I. After the set value of the price is set, the cost of the cargo (goods) is automatically recorded on the display panel of value.

The claimed technical solution allows you to create compact electronic scales that are convenient to use in everyday conditions, when there is a need for a fairly accurate determination of the weight of the weighed cargo (goods) and its cost. Moreover, weighing can be done both when working in stationary mode with a bowl, and when weighing suspended cargo in hook mode.
