Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to the attached drawings, the embodiment of the invention provides an alloy raw material conveying control system, which comprises a conveying belt 1, wherein three feeding devices are butt-jointed to the conveying belt 1 and used for conveying alloy raw materials onto the conveying belt 1.
The feeding devices comprise a first feeding device 2 controlled by a first control module 21, a second feeding device 3 controlled by a second control module 31 and a third feeding device 4 controlled 41 by a third control module; the first control module 21, the second control module 31 and the third control module 41 are all electrically connected. The first feeding device 2, the second feeding device 3 and the third feeding device 4 are all conveyor belts which are sequentially arranged on a conveying path of the conveying belt 1; the first control module 21, the second control module 31 and the third control module 41 are all connected in series with a start-stop switch of the conveying belt 1.
Still be equipped with material height monitoring devices on conveyor belt 1, material height monitoring devices is including setting up the limit switch 52 in conveyor belt 1 top, material height monitoring devices's limit switch 52 is connected with electricity between first control module 21, second control module 31 and the third control module 41 respectively. The limit switch 52 is connected with a movable baffle 51. The material height monitoring device further comprises an inverted U-shaped frame 5 with a downward opening, supporting columns of the inverted U-shaped frame 5 are respectively arranged on two sides of the conveying belt 1, and the movable baffle 51 is arranged on a cross beam of the inverted U-shaped frame 5.
The embodiment also provides an alloy raw material conveying control method of the alloy raw material conveying control system, which comprises the following steps:
the conveying belt 1 is electrified to run, and the first feeding device 2, the second feeding device 3 and the third feeding device 4 enter a standby state;
after receiving the start command, the first control module 21 of the first feeding device 2 determines whether the second feeding device 3 is in the operating state through the second control module 31:
if the second feed device 3 is in the operating state, the first control module 21 of the first feed device 2 does not execute the start command;
if the second feeding device 3 is in the stop state, the first control module 21 judges whether the third feeding device 4 is in the operation state through the third control module 41:
if the third feeding apparatus 4 is in the operation state, the first control module 21 of the first feeding apparatus 2 does not perform the start command;
the first control module 21 of the first feeding apparatus 2 executes the start command if the third feeding apparatus 4 is in the stopped state.
In this embodiment, the number of the feeding devices is three, and therefore, it is sufficient to determine the third feeding device 4. In other embodiments, the number of feeding devices may be larger, and subsequent feeding devices may need to be judged to ensure that no other feeding device is in operation before the feeding device is started.
After the first control module 21 executes the start command to operate the first feeding device 2, the following steps are further executed:
whether the material height monitoring device monitors and judges whether the material height on the conveying belt 1 exceeds a threshold value:
if yes, the conveying belt 1 is powered off and stopped;
if not, the conveyor belt 1 remains running.
By adopting the alloy raw material conveying system and the control method provided by the technical scheme, the feeding equipment cannot be started before the conveying belt 1 does not run, so that the alloy raw materials are prevented from being transported to the conveying belt 1 to be accumulated and cannot be timely transported away. The control modules of the feeding equipment are electrically connected with each other, so that the synchronization of the running state information is realized, and only one feeding equipment can transfer the alloy raw materials to the conveying belt 1 when the system runs.
When the height of the alloy raw material stacking on the conveying belt 1 exceeds a threshold value, the movable baffle plate 51 is driven to deflect, and therefore the limit switch 52 connected with the movable baffle plate 51 is triggered. After being triggered, the limit switch 52 sends an electric signal to a control module of the running feeding device, so that the feeding device stops feeding, and the alloy raw materials transferred to the conveying belt 1 are prevented from being overweight to cause device damage. The adoption erects the U-shaped frame 5 of falling on conveyor belt 1 and sets up adjustable fender 51 and limit switch 52, can support more steadily, avoids the alloy raw materials transportation picture to promote the stress that the adjustable fender 51 was applyed when drawing to the support and leads to support deformation, influences monitoring effect.
The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
