Embodiment Construction

[0011] An electronic scale for container turning machine, such as figure 1 with figure 2 Shown: It is composed of pressure detection unit, position detection unit, CPU central control unit, nixie tube display, keyboard and printer. All kinds of devices are market commodity devices. The connection relationship of each component is: the pressure detection unit is composed of Two pressure sensors, I / V circuit and A / D conversion circuit form a weight acquisition channel. In order to avoid external interference during work, the 8253 pressure sensor (Switzerland Trafag Company) adopts a two-wire pressure transmitter with an output of 4-20mA The current signal and the pressure sensor are connected to the well-known I / V conversion circuit, high and low frequency filter circuit and analog-to-digital A / D converter, and the sampled value is input into the data input bus of the CPU central control unit. The specific connection relationship is: Type 8253 inlet pressure sensor 1 is connecte...

Abstract

The invention provides a measuring and weighing device arranged on a container turnover machine, and discloses an electronic scale of a container turnover machine. The electronic scale comprises a pressure detection unit, a position detection unit, a CPU, a nixie tube displayer, a keyboard and a printer. According to the pressure detection unit, two pressure sensors are arranged on an upper cavity oil circuit and a lower cavity oil circuit of a lifting oil cylinder respectively, and a weight acquisition channel of the CPU is formed by the two pressure sensors, an I / V circuit and an A / D converter. According to the position detection unit, position sensors are arranged on a base and a limiting frame respectively, and a position detection channel of the CPU is formed by the position sensors and a photocoupling circuit. A man-machine conversation channel is formed by a display unit, the keyboard and the printer. According to the technical scheme, the purpose that goods are automatically weighed and measured while container loading and unloading of the goods are carried out is achieved, and the technical problem that container loading and unloading of the goods are not quantified is solved. The overload problem in the goods transportation process is solved from the source, and transportation safety is guaranteed. The electronic scale of the container turnover machine has the advantages that measurement is accurate, the structure is simple, and the automation degree is high.

Description

technical field [0001] The invention relates to a metering and weighing device, in particular to an electronic scale for a container turning machine that automatically weighs and measures the goods while loading and unloading the goods in the container. Background technique [0002] Container transportation is a convenient and fast mode of transportation nowadays, and container tilting or erecting equipment (patent number: 201220141889.1) is a kind of mechanical equipment widely used in container transportation, storage and transportation industries, and does not have weighing function . With the development of social economy and the needs of enterprise management, in line with the principle of safe transportation, the requirements for cargo handling are getting higher and higher. The loading and unloading of goods is carried out in accordance with standardized operations, and the implementation of weighing and measuring of goods is the development direction of the loading ...
