Referring to fig. 1-8, a full-automatic magnetic core tube filling machine includes a feeding assembly, a transporting assembly and a tube filling assembly 3, which are sequentially connected, wherein the feeding assembly includes a vibration material arranging tray 1, the vibration material arranging tray 1 is used for conveying magnetic core blocks onto the transporting assembly, the transporting assembly is used for conveying the magnetic core blocks to the tube filling assembly 3, the tube filling assembly 3 includes a feeding groove, a pushing rod 33 and a receiving tube 31, an opening of the receiving tube 31 is opposite to one end of the feeding groove, the pushing rod 33 is slidingly arranged at the same time, the feeding groove, the pushing rod 33 and the receiving tube 31 are positioned on the same straight line, since the magnetic core blocks are arranged in a tubular structure firstly in order to facilitate subsequent production in the production process of the magnetic core tubes, when the transporting assembly conveys the magnetic core blocks to the tube filling assembly 3, the pushing rod 33 pushes the magnetic core blocks into the receiving tube 31, the pushing rod 33 is arranged on a telescopic electric cylinder 332 and moves back and forth along the axial direction of the pushing rod 33 under the driving of the electric cylinder, a certain interval space exists between the pushing rod 33 at two ends of the feeding groove and an opening of the receiving pipe 31, which is close to one side of the pushing rod 33, one side of the interval space in the feeding groove is provided with an opening, the transporting component is arranged at one side of the opening and communicated with the interval space through the opening, and is vertical to a connecting line between the pushing rod 33 and the receiving pipe 31, when the magnetic core blocks are fed into the feeding groove along the opening by the transporting component during pipe loading, the magnetic core blocks are blocked by the side wall of the feeding groove, at the moment, the magnetic core blocks stay in the interval space between the pushing rod 33 and the opening of the receiving pipe 31, then the pushing rod 33 stretches out towards the opening of the receiving pipe 31, the magnetic core blocks enter the receiving pipe 31 through the opening of the receiving pipe 31 under the driving of the pushing rod 33, and then, the feeding of single magnetic core blocks is completed, the vibration material arranging disc 1 continuously sends the magnetic core blocks to the conveying assembly, the conveying assembly and the material pushing rod 33 continuously repeat the above actions until enough magnetic core blocks fill the material collecting pipe 31, and automatic tube loading of the magnetic core blocks is completed.
Specifically, the transportation assembly comprises a transportation track 2, the transportation track 2 comprises a conveyor belt 21 and a conveying motor 24 for driving the conveyor belt 21, one end of the conveyor belt 21 is connected with a discharge hole of the vibration material arranging disc 1, the other end of the conveyor belt 21 is connected with a space to be filled with tubes, and the conveyor belt 21 sends magnetic core blocks from the vibration material arranging disc 1 to the feeding groove until the magnetic core blocks are blocked by the baffle plate.
In the above process, when one receiving tube 31 is completely filled, an operator needs to take down the filled receiving tube 31 to put a new tube, or empty the filled receiving tube 31, and then a stop is needed to affect the production efficiency, therefore, the invention comprises a plurality of receiving tubes 31 parallel to each other, the plurality of receiving tubes 31 are connected with each other and can translate in the direction perpendicular to the axial direction under the action of a receiving driving motor 32, the receiving tubes 31 on one side of the edges of the plurality of receiving tubes 31 are aligned with the pushing rods 33, when the first receiving tube 31 is filled, the receiving driving motor 32 drives the plurality of receiving tubes 31 to translate until the second receiving tube 31 is aligned with the pushing rods 33, at this time, the pushing rods 33 continue pushing magnetic core blocks, and the magnetic core blocks enter the second receiving tube 31.
In actual production, the tubing speed is sometimes required to be adjusted according to the field conditions such as production plan, in the structure, the subsystems such as the transportation assembly, the feeding assembly and the tubing assembly 3 have no unified control system and control parameters, so that when the tubing speed needs to be adjusted, the control system needs to respectively adjust the parameters related to each subsystem and the running speed connected with the control system to be close to the target value, so that each system synchronously reaches the target speed, and the parameter calculation modes among different subsystems are different, therefore, by respectively adjusting the parameters to be close to the target speed, the asynchronous results are possibly caused, the situation that the magnetic core blocks extend before reaching the feeding groove, so that the magnetic core blocks need to be retracted in the feeding groove 33 and then be pushed into the receiving groove 31 normally, the tubing efficiency is influenced, the magnetic core tube filling machine also comprises a control module 4, wherein the control module 4 is electrically connected with the pushing rod 33 and instructs the pushing rod 33 to push the magnetic core blocks into the plurality of receiving tubes 31, meanwhile, the control module 4 is electrically connected with the conveying motor 24, the control module 4 is pre-input with the total length s of the conveying track 2, the control module 4 controls the feeding time t of the conveying belt 21 by controlling the rotating speed of the conveying motor 24, when in use, an operator can calculate the time t required by the single magnetic core block required by the production rate on the conveying belt 21 and then input t into the control module 4, the control module 4 calculates the linear speed v of the conveying motor 24 and instructs the conveying belt 21 to operate at the linear speed v according to the output result of a function v=s/t, meanwhile, the control module 4 calculates the linear speed v of the conveying motor 24 and the conveying belt 21 according to the value of t, the front-back push-pull frequency f of the pushing rod 33 is calculated according to the output result of the formula f=1/t, the telescopic frequency of the telescopic electric cylinder 332 is instructed, and the telescopic frequency of the pushing rod 33 is further changed, at this time, the telescopic frequency of the pushing rod 33 and the conveying speed of the conveying belt 21 are parameters related to t only, when the feeding time t changes according to the requirement, the operation parameters of the pushing rod 33 and the conveying belt 21 can uniformly change according to t, the condition that the feeding is inaccurate due to the interference of other factors on the parameters is avoided, and the accuracy is improved by setting the control module 4 respectively electrically connected with the conveying assembly and the tubing assembly 3 and setting the telescopic frequency of the pushing rod 33 and the conveying speed of the conveying belt 21 to function output values related to t only, so that the conveying assembly and the tubing assembly 3 can synchronously change when the feeding speed is changed, the unsynchronized due to the fact that the parameter calculation modes are different between subsystems is avoided.
In order to avoid mechanical failure caused by too high feeding speed and simultaneously avoid that the feeding speed is too slow so that the linear speed of the conveying motor 24 corresponding to the feeding time is smaller than the optimal running speed of the motor, the control module 4 is pre-input with the standard feeding time t of the motor 0 Meanwhile, the feeding time t is in the range of 0.25t 0 <t<4t 0 When t is greater than this range, the control system causes t=4t 0 When t is less than this range, the control system causes t=0.25t 0 By inputting the standard feeding time and the t value range in advance, the condition that the mechanical fault or the optimal running speed of the motor is exceeded is avoided.
In the process of the construction of the tubing operation, since the magnetic core blocks are made of various materials, the hardness of part of the magnetic core blocks is low, and the pushing rod 33 is required to push the magnetic core blocks into the tubing 31 by pushing in the tubing process, the magnetic core blocks press the magnetic core blocks which have previously entered the tubing 31 inwards and enter the tubing 31, in the process, the magnetic core blocks collide with the rest of the magnetic core blocks, and when the hardness of the magnetic core blocks is low, physical damage occurs in the collision process, the quality of the magnetic core in the tubing is affected, in order to avoid such occurrence, the feeding buffer 35 is arranged right above one end of the feeding trough close to the tubing 31, the feeding buffer 35 comprises a blower, the blowing port of the blower is arranged towards the right lower side, and the blowing is continuously carried out at one end of the feeding trough close to the tubing 31 in the tubing process, when the core block to be assembled is close to the previously-entered core block of the receiving pipe 31 at the opening of the receiving pipe 31, the core block to be assembled and the feeding groove form a semi-open space, high-pressure gas blown out by the blowing machine is filled in the semi-open space, the pressure of the gas in the semi-open space is increased to cause acting force opposite to the advancing direction on the core block, meanwhile, when the core block to be assembled is close to the core block to be assembled, the telescopic rod is in the tail end of an extending period, the whole telescopic rod is in a decelerating state, external force in the advancing direction is stopped to be provided for the core block, so that the resistance provided by the core block to be assembled by the high-pressure gas can reduce the advancing speed of the core block, the collision force between the core blocks is reduced, in addition, the closer the core block to be assembled is, the formed semi-open space is smaller, the compressed volume of the high-pressure gas in the semi-open space is smaller at the moment, the larger the external expansion acting force is, the larger the resistance of the high-pressure gas to the deceleration action of the high-pressure gas is along with the approach of the magnetic core blocks to be assembled to the receiving pipe 31, the further the speed and the collision force between the magnetic core blocks are reduced, and the collision force between the magnetic core blocks and the damage probability of the magnetic core in the pipe are reduced by arranging the feeding buffer 35.
In the process of buffering the magnetic core blocks by the feeding buffer 35, when the blowing power is too large, there is a probability that the gas resistance is larger than the thrust force of the pushing rod 33, so that the magnetic core blocks cannot smoothly enter the material receiving pipe 31, the accuracy of the pipe loading is affected, when the blowing power is too small, there is a probability that high-pressure gas cannot provide resistance for the magnetic core blocks to be loaded well, the probability of reducing the damage of the magnetic core blocks in the pipe cannot be fully exerted, in order to consider the accuracy of the pipe loading and the quality of the magnetic core in the pipe, the control module 4 is electrically connected with the blowing machine, and the control module 4 inputs the standard power p of the blowing machine in advance 0 The control module 4 controls the operation according to t and t 0 And p 0 Changing the operating power p of the blower, where p=p 0 ×t 0 /t；
When t is reduced, the feeding time is shorter, the feeding speed, the running speed of the pushing rod 33 and the speed of the magnetic core block are faster, the magnetic core block to be assembled needs larger resistance to reduce the speed of the magnetic core block, and the power p of the buffer is higher 0 ×t 0 Increasing/t, improving resistance of gas to the magnetic core block to be assembled, and improving resistance to the magnetic core block so as to improve the deceleration effect to the magnetic core block;
when t is increased, the feeding time is longer, the feeding speed, the running speed of the pushing rod 33 and the speed of the magnetic core block are slower, the magnetic core block to be assembled does not need larger resistance buffering, and the power p of the buffer is higher 0 ×t 0 Reduced/t, reduced resistance of the gas to the core block to be filled by electrically connecting the control module 4 to the blower and making the control module 4 operate according to the function p=p 0 ×t 0 The output value of/t changes the power of the blower, completes the adjustment of the blower power according to the feeding speed, and gives consideration to the accuracy of the tubing and the buffering function.
Meanwhile, by setting the value of p to be a function related to t only, the synchronization level of each system in the tube filling machine can be further improved, the condition of the loading buffer 35, the transport assembly and the tube filling assembly 3, which are respectively controlled by independent parameters, is prevented from being asynchronous, and the accuracy of tube filling is further improved.
