Problems solved by technology

There is a very big disadvantage of "manually calling the pot": when there are many casting equipment, it is very easy for the personnel of two casting stations to call the pot for the RGV personnel at the same time. Equipment downtime

Embodiment Construction

[0089] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0090] In view of the low production efficiency caused by manual operation of RGV trolleys, the dispatching system for RGV trolleys suitable for the foundry industry can control each trolley to complete a series of instructions in real time according to the current production status, improve the operating efficiency of the trolleys, and shorten the material consumption. The replacement time reduces the idle time of the equipment, and at the same time greatly reduces the cost of personnel, avoiding the risk caused by human error. The production line of this embodiment must contain more than two casting equipment, and it is equipped with a transfer table for placing aluminum crucibles and an RGV trolley for replacing aluminum crucibles.

[0091] The on-site interface provides production...

Abstract

The invention discloses a method for calculating a transfer trolley scheduling task in real time. The method comprises the following steps of 1, acquiring field information of a casting machine production line, and recording the field information; 2, screening out a pot changing demand queue, and calculating remaining time of molten aluminum of each casting machine production line in the queue; and 3, creating a pot changing task, calculating planned starting time of the pot changing task and the available time of subsequent tasks according to the current time and the molten aluminum remainingtime, wherein the planned starting time of the subsequent tasks is not shorter than the available time of the subsequent tasks. According to the method, the reasonable planned starting time of the pot changing task can be accurately calculated according to the casting machine information, when multiple casting devices need molten aluminum at the same time, the previous pot changing task starts tochange pots in advance, and subsequent devices are ensured not to stop.

Description

technical field [0001] The invention belongs to the field of casting industry production lines, in particular to the fields of casting informatization and casting automation, and specifically relates to a scheduling method for changing pots of aluminum liquid transfer trolleys in the foundry industry. Background technique [0002] The materials used in foundry factories are mainly aluminum ingots. Generally, aluminum ingots are turned into molten aluminum through a melting furnace. The RGV (Rail Guided Vehicle) trolley carries the molten aluminum in a crucible and sends the crucible filled with molten aluminum to the degasser. The degasser After alloying the molten aluminum, it is sent to the casting machine through the RGV trolley. The casting equipment hydraulically casts the aluminum in the crucible into a product, and then the empty crucible is sent to the melting furnace through the RGV trolley to be filled with molten aluminum, and then sent to degassing Machine alloy ...
