Problems solved by technology

Although this method changes the measurement method of the electronic scale and meets the requirements in terms of accuracy, it also has several disadvantages. First, the measurement bucket is a static measurement, and the bucket capacity only meets the volume of a grab bucket. Therefore, each time the receiving bucket is finished receiving materials , when the material is put into the weighing bucket for weighing, in order not to generate vibration, the grab bucket of the ship unloader must stop working, and the next cycle of operation can only be carried out when the weighing bucket is completed, which leads to non-continuous operation and Greatly reduces the unloading efficiency of the ship unloader
Second, since the normal ship unloader has only one layer of buckets, after adding two layers, the height of the ship unloader has increased a lot, so that the lifting height of the grab bucket to pick up materials has increased, and the cycle of picking up materials has become longer. After measurement, the time Longer, so that after the previous discharge of the hopper is completed, the next material has not been put down, which greatly reduces the production efficiency of the port, and the whole system is too complicated, there are many equipment failure points, and the maintenance workload is quite large, which cannot be obtained. actual application

Embodiment Construction

[0046] Each step of the present invention will be further described in detail below.

[0047] S1. Check that the system is normal, and start the metering mode. In the metering mode, the operator of the ship unloader has no right to control the metering process.

[0048] When starting to work, check whether the various parts and mechanisms of the ship unloader are in normal condition and start the metering mode. In the non-metering mode, the on-site operators can control each step of the metering process by themselves. In the metering mode, the operator has no right to control the metering process, but must measure according to the flow set by the metering mode. For the convenience of management and operation, The metering mode can be remotely selected and locked, so that it can be guaranteed to work in the metering mode when needed, preventing the operator of the ship unloader from using the non-metering mode privately for the sake of efficiency or trouble, resulting in inaccu...

Abstract

The invention relates to a ship unloader metering mode control method. The method comprises the following steps: S1) detecting whether a system is normal and starting a metering mode; S2) carrying out grab hopper material taking, and after receiving a material discharging instruction, discharging material to a measuring hopper; S3) weighing rough weight of the material in real time through a metering device, wherein the metering device carries out material rough weight weighing after the instrument value of the metering device is stable; S4) opening a gate of the measuring hopper and discharging the material to a discharge hopper, and after discharging is finished, closing the gate of the measuring hopper; S5) weighing tare weight of the material through the metering device, wherein the metering device carries out material tare weight weighing after the instrument value of the metering device is stable; S6) calculating the weight of the material; and S7) repeating the steps S2)-S6). The reasonable and high-efficiency ship unloader metering mode control method guarantees metering precision of a ship unloader and improves discharging efficiency of the ship unloader, and guarantees transaction fairness and enterprise production operation efficiency.

Description

technical field [0001] The invention relates to a control method of a ship unloader, in particular to a control method of a metering mode of a ship unloader. Background technique [0002] In the existing port operation process, the electronic belt scale is generally used to measure the goods. The electronic belt scale belongs to continuous dynamic measurement. Although with the development of technology, the theoretical measurement accuracy of the electronic belt scale can reach 0.5%, but in In the actual work of the terminal, due to the influence of the use environment, wind force, material characteristics, weather and temperature changes, the 0 point drift of the electronic belt scale after calibration is relatively large, and the actual measurement error is far greater than 0.5%, which is far from the theoretical accuracy. Therefore, the electronic belt scale can only be used as an internal management measurement, and the parties to the transaction cannot accept such a me...
