Problems solved by technology

[0004] 1) The first type of equipment is completely dependent on human operation, CO 2 Whether the filling quality and filling quantity of gas cylinders are safe or not depends on personal operation. Even if some equipment is equipped with weight auxiliary alarm function, due to CO 2 The weight of the gas cylinders is not exactly the same, so although it can guarantee the CO 2 Needed for cylinder safety, but cannot guarantee CO 2 Standard volume filling of gas cylinders
[0005] 2) The second type of equipment, although highly integrated and low in cost, is not suitable for production workshops with large vibration, noise and dust

Embodiment 1

[0030] CO of Special Gas Operation Department of Beizhong Group 2 Take gas automatic filling equipment as an example.

[0031] 1. Preparation before work

[0032] The present invention adopts special-purpose PLC, and CPU adopts LM3109 module. The controller has the logic operation function of the computer and its own load carrying capacity.

[0033] (1) Control hardware

[0034] One piece of LM3109 (PLC), one piece of HT7000 touch screen (10-inch screen), four electronic scales, four solenoid valves, eight intermediate relays, four buttons, four indicator lights, one communication cable, one control box, empty Open 1, CO 2 4 cylinders, CO 2 2 storage tanks and 1 electric piston pump.

[0035] LM3109 module is installed in the control box, intermediate relays, communication cables, and several signal lines, and HT7000 touch screen (10-inch screen), buttons, and indicator lights are installed on the control box panel.

[0036] CO of the present invention 2 Gas storage ta...

Abstract

The invention relates to a gas charging device and a method, and particularly relates to a CO2 gas charging control device and a control method. A CO2 liquid cylinder manifold is connected to CO2 cylinders through head clamps. The CO2 cylinders are disposed on electronic scales. The electronic scales send weights of the CO2 cylinder to a PLC through signal transmission. The PLC is connected to a touch screen. A PLC on-off output terminal controls opening and closing of magnetic valves on charging pipelines through intermediate relays. According to the device and the method, problems of the potential safety hazards and unstable product weights, which are caused by human factors, are overcome, weighting devices are high in shock resistance, impact error is eliminated, and weight accuracy in a charging process is ensured.

Description

technical field [0001] The invention relates to a gas filling device, in particular to a CO 2 Gas filling control device and control method. Background technique [0002] Currently domestic bottled CO 2 The filling equipment is divided into the following categories: 1. The filling equipment is manually controlled by CO 2 The filling weight of the gas cylinder, or the equipment has a weight auxiliary alarm function. 2. A computer-based control system composed of electronic scales, pressure sensors, solenoid valves, single-chip microcomputers, communication modules and computers equipped with Labview programs. [0003] The shortcoming and deficiency that adopt above-mentioned equipment to produce are as follows: [0004] 1) The first type of equipment is completely dependent on human operation, CO 2 Whether the filling quality and filling quantity of gas cylinders are safe or not depends on personal operation. Even if some equipment is equipped with weight auxiliary alarm...
