Description

Commercial electronic-weighing system

Technical field

The utility model relates to a kind of commercial electronic-weighing system.

Background technology

Electronic scales is easy to operate because of it, accurate measurement, be widely used in various retail markets, but the weight of object and the amount of money all adopt the digital mode video data of charactron or liquid crystal, the observation habit that not too meets people, and cause client easily to the obscuring of weight, unit price and the amount of money of object, client often will through careful screen weight, unit price and three display windows of the amount of money after, could distinguish the meaning of the three groups of digital representatives that come; On the other hand, the weighing function of conditional electronic scale is separated with function for receiving cash, has also brought inconvenience to the cashier.

Summary of the invention

The purpose of this utility model has provided a kind of open-and-shut commercial electronic-weighing system of weight, unit price and the amount of money of observing simple, functional diversities, client to purchasing commodity.

The technical scheme that this electronic scales addresses the above problem is as follows:

A kind of commercial electronic-weighing system, comprise two-sided indication box, weighing platform, cash box, LOAD CELLS, signal conditioning circuit, single-chip microcomputer, the two-sided indication box of its electronic scales is that a medial surface is to cashier, the Customer Facing data presentation device in the outside, include two-sided index dial and pointer, two-sided LCDs, its pointer is driven by the driving shaft of two-sided axis of symmetry stepper motor.

For convenience the cashier checks continuous data, and described two-sided indication box includes inboard index dial PVC plate on cashier's the medial surface, sticks on weight scale table, inboard pointer, inboard Liquid Crystal Module and operation push-button on the inboard index dial PVC plate.

For convenience client checks continuous data, the including outside index dial PVC plate on shopper's the lateral surface, stick on weight scale table, outside pointer and outside Liquid Crystal Module on the index dial PVC plate of the outside of described two-sided indication box (1).The demonstration of two-sided indication box is divided the work, and adopts tuning drive gear to show weight of object, adopts the unit price of liquid crystal display display of commodity and the amount of money of the commodity of purchasing, and cashier and client can observe the metering result simultaneously.

Described two-sided pointer box inside comprises a two-sided axis of symmetry stepper motor, one end of this stepper motor output shaft passes the center pit of inboard index dial PVC plate, link to each other with inboard pointer, the other end of output shaft passes the center pit of outside index dial PVC plate, link to each other with outside pointer, two-sided axis of symmetry stepper motor, is driven inboard pointer simultaneously and rotates with outside pointer when the axle of motor rotates by Single-chip Controlling.

The fixed form of two-sided indication box is as follows, two-sided indication box is fixed on the end that a centre is hollow straight pipe, the centre that the other end of straight pipe inserts 90 ° of bendings is in the hollow pipe, and be fixed together by connecting screw, the other end of bend pipe is connected on the side of weighing platform.

Described weighing platform is the bearing platform of a rectangular parallelepiped, frame stands on the cash box, the bottom of weighing platform is a pressure transducer, send the A/D end of convert of single-chip microcomputer to handle after the weight signal feed signals modulate circuit that pressure sensing dress device collects, modulate circuit amplify it.

On four angles of described weighing platform bottom a height adjustable spiral leg is arranged respectively, comprise the knob of a spiral on each spiral leg, can adjust the levelness that weighing platform is installed by the twisting knob.

Weighing platform is connected by linkage and cash box are movable, two one-armed hinge terminals are arranged on the weighing platform, the hinge terminal that two ears are arranged on the cash box, during installation, weighing platform places on the cash box, the hinge terminal that it is one-armed inserts between the hinge terminal of ears, passes its connecting hole by latch respectively, and weighing platform and cash box are connected as a single entity.
