Step S104: and judging whether the sectional information in the register corresponding to the pick head clamping position on the alignment roller way is the sectional information of the bar section to be cut.
And shearing a rolled piece into even sections according to the multiple length shear, wherein if the rolled piece is 4 sections, the 4 th section is a tail section, namely a section of the bar to be cut. According to the clamping movement rule in the step S103, the bar section to be cut always moves on the odd-numbered clamping position, so that the picking head clamping position is No. 85 clamping position, when the register assignment of the No. 85 clamping position is detected to be 4, the bar section to be cut on the No. 85 clamping position is indicated, and the bar section to be cut reaches the preset picking head position.
And shearing a rolled piece into odd sections according to the multiple length shear, wherein if 5 sections exist, the 5 th section is a tail section, namely a section of the bar to be cut. According to the position-clamping movement rule in the step S103, the bar segment to be cut may be on an even position-clamping or an odd position-clamping, so that the picker position is the position of position 84 and position 85, the bar segment to be cut reaches the preset picker position, when the register value of the position 84 is detected to be 5 or the register value of the position 85 is detected to be 5, the bar segment to be cut is indicated on the position 84 or position 85, and the bar segment to be cut reaches the preset picker position.
The method can be called as a register tracking method, and whether the section of the bar to be cut reaches the preset picking head position or not can be known by tracking the stored value of the register through the PLC.
The embodiment of the present application further provides another non-tracking method for determining whether a section of a bar to be cut reaches a preset picking position, referring to fig. 3, which is a schematic flow diagram of another method for determining that a section of a bar to be cut is in place, as shown in fig. 3, the method includes the following steps:
in the method, the first picking action of the picking device needs to manually judge whether the section of the bar to be cut reaches No. 84 clamping position or No. 85 clamping position, and the subsequent steps S111-S113 can be executed to judge whether the section of the bar to be cut reaches No. 84 clamping position or No. 85 clamping position.
Step S111: and judging whether the total shearing section number N is an even number when the rolled piece is sheared into a plurality of first-level bar sections.
The section of bar to be cut and the remaining sections of bar are collectively referred to as a first-level section of bar. According to the clamping movement law set forth in the step S103, when the rolled piece is cut into even sections, the clamping position of the section of the bar to be cut always moves on the odd clamping position, only the picking device on the No. 85 clamping position works, and the picking device on the No. 84 clamping position does not work; when the rolled piece is cut into odd sections, the head raising devices on the No. 84 and No. 85 clamping positions need to work. Therefore, the total number of shear stages N needs to be determined.
Step S112: if the total number N of the shearing sections is an even number, the first-stage bar section moves two clamping positions once according to the action of the stepping cooling bed, and whether the stepping cooling bed acts t0 times after the head picking device acts last time is judged, wherein t0 is N/2.
When N is an even number, if the step cooling bed moves once, and the bar segment on each block moves two blocks, after the step cooling bed moves N/2 times, each segment of the next rolled piece reaches the position of each segment of the previous rolled piece, because the picking device starts the first picking motion through manual judgment before step S111, that is, the bar segment to be cut is located at position 84 in the previous rolled piece, the bar segment to be cut is located at position 84 whenever the step cooling bed moves N/2 times.
For example, when N is 4 and M is 2, the section of rolled stock to be cut is moved to the index 84 whenever the stepping cooling bed moves twice.
Step S113: if the total number of the shearing sections is odd, the first-stage bar section moves two clamping positions according to the action of the stepping cooling bed once, and whether the stepping cooling bed acts t1 times after the first picking device acts last time or whether the stepping cooling bed acts t2 times after the second picking device acts last time is judged, wherein t1 is [ N/2] +1, t2 is [ N/2], the first picking device is a picking device on an even clamping position, and the second picking device is a picking device on a next clamping position adjacent to the first picking device.
When N is an odd number, if the step cooling bed moves once, and the bar segment on each block moves two blocks, then after the step cooling bed moves (N/m +1) times, each segment of the next rolled piece will be staggered by one block from each segment of the previous rolled piece, because the picking head device starts the first picking head movement through manual judgment before step S111, and if the bar segment to be cut is located at position 84 in the previous rolled piece, the bar segment to be cut is located at position 85 every time the step cooling bed moves ([ N/2] +1) times.
If the bar section to be cut in the last rolled piece is positioned at No. 85 clamping position, the bar section to be cut is positioned at No. 84 clamping position every time the stepping cooling bed moves (N/2) times.
Step S200: if the bar material is arrived, the picking head device at the preset picking head position is controlled to pick up one end of the bar material section to be cut to the position above the stop table at the tail end of the alignment roller way.
When the tracking method is used, if a rolled piece is cut into even sections by the multi-length shear, the section of the bar to be cut is positioned on the position clamping position 85, and at the moment, the second picking head device is controlled by the PLC controller to pick up one end of the section of the bar to be cut on the position clamping position 85 to the position above the stop table aligned with the tail end of the roller way; if a rolled piece is cut by the multiple length and is cuted to the odd number section, for waiting to cut the rod section in according to No. 84 screens, at this moment, through the first take-off equipment of PLC controller control with the one end of waiting to cut the rod section on No. 84 screens pick up the terminal fender platform top of alignment roll table, for waiting to cut the rod section in according to No. 85 screens, at this moment, through the one end of waiting to cut the rod section of PLC controller control second take-off equipment on with No. 85 screens to pick up the terminal fender platform top of alignment roll table.
When the tracking method is not used, when the bar section to be cut reaches the picking head clamping position is judged according to the action times of the stepping cooling bed after the picking head device acts last time, the corresponding picking head device is controlled to pick one end of the bar section to be cut to the position above the stop table at the tail end of the alignment roller way.
Step S300: the control is aligned the roll table and is kept off the platform motion towards, makes and waits to cut rod section and second grade baffle and align, aligns all the other rod sections on the roll table and aligns with one-level baffle, and wherein, second grade baffle vertical fixation is in the top of keeping off the platform, and one-level baffle vertical fixation is on keeping off the side of the orientation alignment roll table of platform, and second grade baffle and one-level baffle are parallel and are provided with the interval of predetermineeing on the horizontal direction.
