Detailed Description
In order to make the present invention better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For easy understanding, referring to fig. 1, the embodiment of a control method of a full-automatic round tube laser blanking machine is provided, and the control method is applied to a full-automatic round tube laser blanking machine with a first photoelectric sensor arranged below a cutting head and a second photoelectric sensor arranged in a feeding clamping mechanism and used for detecting a tail, and the control method comprises the following steps:
step 101, a PLC controller obtains the distance between a first photoelectric sensor and a second photoelectric sensor.
Step 102, when the first photoelectric sensor detects the material pipe, the PLC controls the feeding clamping mechanism to feed reversely, when the first photoelectric sensor cannot detect the material pipe, controls the feeding clamping mechanism to stop feeding reversely, controls the feeding clamping mechanism to feed forward, conveys the material pipe to a designated position, stops feeding, and controls the cutting head to cut the material pipe.
Step 103, detecting sensing signals of a second photoelectric sensor in real time by the PLC in the feeding and cutting process of the material pipe, acquiring the residual length of the material pipe when the sensing signals of the second photoelectric sensor are not detected, and calculating the cutting times of the residual product according to the residual length of the material pipe and the cutting length of the product, wherein the residual length of the material pipe is the length of the first photoelectric sensor and the second photoelectric sensor, which is overlapped with the length of the material pipe extending out of the first photoelectric sensor, by the distance.
Step 104, the PLC controller judges whether the cutting times of the residual products are integers, if not, the length of the waste products is calculated, and the waste products left after cutting are recovered to a waste product collecting frame through a waste product recovering mechanism, wherein the length of the waste products is the product of the decimal part of the cutting times of the residual products and the cutting length of the products.
It should be noted that the control method in the embodiment of the invention is applied to a full-automatic circular tube laser blanking machine with a first photoelectric sensor arranged below a cutting head and used for detecting a stub bar and a second photoelectric sensor arranged in a feeding clamping mechanism and used for detecting a stub bar. After the first photoelectric sensor and the second photoelectric sensor are arranged, the distance S1 between the first photoelectric sensor and the second photoelectric sensor is recorded in the PLC. When the feeding clamping mechanism positively conveys the material pipe to the first photoelectric sensor, the first photoelectric sensor senses a signal, the sensing signal is fed back to the PLC controller, the PLC controller controls the feeding clamping mechanism to stop forward conveying, and the material pipe is reversely conveyed until the sensing signal of the first photoelectric sensor disappears, the PLC controller controls the feeding clamping mechanism to stop reverse feeding, then controls the feeding clamping mechanism to forward feeding, conveys the material pipe to a preset material head length to a specified position, then stops feeding, and then controls the cutting head to cut the material pipe. When the cutting of the stub bar is completed, the PLC controller controls the feeding clamping mechanism to feed forward according to the set product cutting length S0 and controls the cutting head to cut the material pipe, and for the finished product obtained by cutting according to the product cutting length S0, the PLC controller collects the finished product through the finished product receiving mechanism. In the feeding and cutting process of the material pipe, the PLC detects sensing signals of the second photoelectric sensor in real time, and when the second photoelectric sensor senses no signals, the remaining length of the material pipe is calculated, and the calculation formula of the remaining length D of the material pipe is as follows:
D=S1+S2
wherein S2 is the length of the pipe extending out of the first photoelectric sensor, that is, the length of the pipe that has been conveyed beyond the position of the first photoelectric sensor when the second photoelectric sensor does not sense a signal.
After the PLC calculates the residual length D of the discharging pipe, the PLC calculates the residual product cutting times K according to the residual length D of the discharging pipe and the product cutting length S0, and the calculation formula is as follows:
K=D/S0
when the number of times K of cutting the residual product is an integer, the material pipe is free of waste, when the number of times K of cutting the residual product is not an integer, the material pipe is free of waste, at the moment, the length of the waste needs to be calculated, and then when the material pipe is cut to the length of the residual waste, the PLC controller controls the waste recycling mechanism to recycle the waste left after cutting to the waste collecting frame. The calculation formula of the waste length L is as follows:
L=x×S0
where x is the fractional part of the number of cuts K of the remaining product.
Specifically, the finished product receiving mechanism and the waste recycling mechanism may be composed of a driving device, a finished product frame and a waste material frame, wherein the driving device is used for conveying finished products to the finished product frame and conveying waste products to the waste material frame.
In one embodiment, considering that the feeding clamping mechanism uses a linen wheel to prevent the surface of the feeding pipe from being scratched in the feeding process, the linen wheel has an abrasion outer diameter, so that the tailings which are easy to feed are not very accurate, in order to avoid the problem that the clamp head of the feeding clamping mechanism is unstable due to too short tailings length when clamping the feeding pipe, and the unnecessary yield is reduced, when calculating the length of the waste, whether the calculated length of the waste meets the requirement of the safe length needs is considered, and if the calculated length of the waste according to l=xxs0 meets the requirement of the safe length, the PLC controller controls the waste recycling mechanism to recycle the waste with the length l=xxs0 left after cutting to the waste collecting frame. If the length of the waste product calculated according to l=xxs0 does not meet the safety length requirement, the length L of the waste product is updated to be the product of the fractional part of the number of times of cutting the remaining product and the cutting length of the product, i.e., l=xxs0+s0, and the PLC controller controls the waste product recovery mechanism to recover the waste product with the length l=xxs0+s0, which is left after cutting, to the waste product collection frame.
In one embodiment, since slag still exists in the process of cutting the pipe by laser, a movable slag removing shaft tube can be arranged below a cutting head of the full-automatic circular pipe laser blanking machine to realize slag removing performance in the cutting process of the pipe, and the PLC controller controls the slag removing shaft tube to stretch out when the pipe is fed to a cutting position, collects slag in the cutting process and controls the slag removing shaft tube to reset after the cutting action is finished.
In one embodiment, the PLC controller has an automatic counting function, automatically counts the number of finished products of the cut material pipes, judges whether the current number of finished product cutting reaches a yield target, and if so, controls the feeding clamping mechanism to stop feeding and starts the audible and visual alarm device to remind that the yield reaches the standard.
