That is, the control mechanism 200, after receiving the incoming material signal, executes the first-stage material distribution command, the second-stage material distribution command, the third-stage material distribution command, and the first-stage material distribution command … … in a circulating manner.
In short, after receiving the incoming signal, the control mechanism 200 controls the moving distributing platform 301 to move from the first end to the second end of the track 303 and controls the material conveying belt 302 to start feeding, when the moving distributing platform 301 triggers the second limit switch 305 at the second end of the track 303, the moving distributing platform 301 is controlled to move reversely for a second preset time after delaying for a first preset time, then the moving distributing platform 301 reverses again, the moving distributing platform 301 reciprocates between the two ends of the track 303, the cycle is entered, and each reversing time, the moving distributing platform 301 delays for a period of time and then drives reversely.
In the process of reciprocating movement of the movable distribution platform 301 between two ends of the track 303, a two-end limiting mode can be adopted, the first limit switch 304 and the second limit switch 305 are triggered to carry out reciprocating control as nodes respectively, but the control method is complex, periodic short-circuit operation needs to be carried out on the two limit switches, and the failure rate of the short-circuit operation is relatively high. Since there may be a certain deviation in the start position of the movable cloth table 301, when the movable cloth table 301 starts to move the cloth from the first end to the second end, the second limit switch 305 is used as a trigger node to perform the reverse control.
In order to ensure the accuracy of the return stroke of the movable distributing platform 301 according to time control, the driving of the movable distributing platform 301 adopts a mode of combining fixed power and fixed speed, when the movable distributing platform 301 is started from a static state, constant power driving is adopted, and after the speed reaches the rated speed, constant speed walking is carried out, so that the constant walking path of the movable distributing platform 301 is ensured in every second preset time.
The above-mentioned circulation of the moving cloth 301 between the two ends of the track 303 is based on the continuous feeding of the feeding mechanism 100, i.e. the above-mentioned circulation is provided that the feeding mechanism 100 continuously sends the feeding signal to the control mechanism 200.
In order to ensure that the material fed from the material outlet 107 of the feeding bin 107 can be fed onto the movable material distributing table 301, the material outlet 107 of the feeding bin 107 is arranged at the middle position of the plurality of melting material bins 400, and the length of the movable material distributing table 301 is not less than half of the material inlet length of the plurality of melting material bins 400. When the moving distributing platform 301 performs continuous circulation distribution, the blanking point always moves back and forth between the second end of the track 303 and the discharging hole 107 of the feeding bin 107, that is, in one continuous circulation, the moving distributing platform 301 performs distribution for half of the plurality of melting bins 400. The coverage area of the blanking point of the movable cloth table 301 is a cloth section, if the movable cloth table 301 adopts a form of uninterrupted movement to perform cloth when the movable cloth table 301 reciprocates to perform cloth, blanking at two ends of the cloth section is less, the uniformity of the cloth is lower, and in order to increase the uniformity of the cloth in the cloth section, delay is performed when the blanking point of the movable cloth table 301 moves to the two ends of the cloth section, and then the movable cloth table reversely moves; during this time, the delivery of the glass batch material thereon by the cloth conveyor 302 is continuous, and thus, more glass batch material can be put on both ends of the cloth section to make the cloth of the cloth section uniform. Specifically, the first preset time is 1 second to 3 seconds, the third preset time is 4 seconds to 6 seconds, and the cloth of the moving cloth stage 301 in the cloth section is more uniform when the first preset time is 2 seconds and the third preset time is 5 seconds. The first preset time and the third preset time are different according to the difference of the preset speed of the movable distributing platform 301, and the faster the preset moving speed of the movable distributing platform 301 is, the shorter the first preset time and the third preset time are, otherwise, the longer the first preset time and the third preset time are.
The feeding ports of the plurality of molten materials are sequentially connected, if the feeding mechanism 100 adopts a continuous feeding mode to feed materials, only half of the plurality of molten material bins 400 can be fed, and in order to ensure that the feeding and distributing device provided by the application can uniformly distribute the whole molten material bins 400, the distributing method of the feeding and distributing device of the glass batch provided by the application adopts a batch-to-batch interval feeding mode. Specifically, after the batch of glass batch is completely fed, the supply of glass batch to the feeding conveyor 101 is interrupted, and the detection device of the feeding mechanism 100 does not detect the glass batch on the feeding conveyor 101, so that the sending of the feeding signal to the control mechanism 200 is interrupted. After the incoming signal is interrupted, the control means 200 issues a stop command to the movable distributing station 301.
Further, the control method further includes:
s40, in the process of controlling the movable distributing platform 301 to move from the first end to the second end of the track 303, if the received incoming material detection signal is interrupted, controlling the movable distributing platform 301 to move continuously, and stopping moving after delaying for a fourth preset time when the movable distributing platform 301 triggers the second limit switch 305;
And S50, in the process of controlling the movable distributing platform 301 to move from the second end to the first end of the track 303, if the received incoming material detection signal is interrupted, controlling the movable distributing platform 301 to continue to operate, and stopping moving after delaying the fourth preset time when the movable distributing platform 301 triggers the second limit switch 305.
That is, in the process of controlling the moving distributing platform 301 to move from the first end to the second end of the track 303, if the received incoming material detection signal is interrupted, the moving distributing platform 301 is controlled to move continuously, and when the moving distributing platform 301 triggers the second limit switch 305, the moving is stopped after a fourth preset time is delayed; in the process of controlling the moving distributing platform 301 to move from the second end to the first end of the track 303, if the received incoming material detection signal is interrupted, the moving distributing platform 301 is controlled to continue to operate, and when the moving distributing platform 301 triggers the second limit switch 305, the moving is stopped after the fourth preset time is delayed. When the signal of the incoming material received by the control mechanism 200 is interrupted and the moving distributing platform 301 performs the step of controlling the moving distributing platform 301 to move from the first end to the second end of the track 303, the control mechanism 200 controls the moving distributing platform 301 to move continuously to the second end of the track 303, controls the moving distributing platform 301 to stop moving after triggering the second limit switch 305 positioned at the second end of the track 303 and delaying for a fourth preset time; when the signal received by the control mechanism 200 is interrupted and the moving distributing platform 301 performs the step of controlling the moving distributing platform 301 to move from the second end to the first end of the track 303, the control mechanism 200 controls the moving distributing platform 301 to move further to the first end of the track 303, and controls the moving distributing platform 301 to stop after triggering the limit switch at the first end of the track 303 or after continuing to perform the step of controlling the moving distributing platform 301 to move from the second end to the first end of the track 303 for a second preset time, and then moving from the first end to the second end of the track 303, and stopping after delaying the fourth preset time.
In short, during the process of distributing, no matter where the movable distributing platform 301 is, as long as the feeding signal is interrupted and the starting position of the movable distributing platform 301 for the present distributing is at the first end of the track 303, the control mechanism 200 controls the movable distributing platform 301 to move towards the second end of the track 303 and to stop after a fourth preset time is delayed after triggering the limit switch of the second end. On the contrary, if the starting position of the movable distributing platform 301 is the second end of the track 303, during the distributing process, no matter where the movable distributing platform 301 is, the control mechanism 200 controls the movable distributing platform 301 to move towards the first end of the track 303 as long as the feeding signal is interrupted, and stops after triggering the limit switch of the first end to delay for a fourth preset time.
In the course of the material distribution, when the time control is adopted to control the distance of the odd-numbered reverse movement of the movable material distribution platform 301, the limit switch at the initial position of the movable material distribution platform 301 is in the state of short-circuit shielding, and after the material supply signal is interrupted, the control mechanism 200 releases the short-circuit shielding of the limit switch. Specifically, the two ends of the limit switch are connected with electromagnetic switches connected in parallel with the limit switch, when the control mechanism 200 receives an incoming signal, the electromagnetic switches are attracted to enable the limit switch to be short-circuited, and when no incoming signal is received, the electromagnetic switches are disconnected to enable the limit switch to work normally.
After triggering the limit switch, the operation is continued for a fourth preset time and then is stopped, so that the movable material distribution platform 301 can avoid the discharge hole 107 of the material feeding bin 107 when stopping, and the material feeding mechanism 100 is prevented from starting to feed materials, but when the movable material distribution platform 301 cannot normally operate due to faults, glass batch materials are accumulated on the movable material distribution platform 301 and even accumulated on the material feeding bin 107 and the material feeding conveyor belt 101, so that equipment is damaged.
The movable distributing platform 301 starts distributing materials from the first end of the track 303, the distributing section is a half area close to the second end of the track 303, and after the distributing is finished, the movable distributing platform 301 stops at the second end of the track 303; next cloth moving stage 301 starts to open cloth from the second end of rail 303, the cloth section is a half area near the first end of rail 303, and after cloth is finished, moving stage 301 stops at the first end of rail 303. In this way, the plurality of melting bins 400 are uniformly distributed. To increase the uniformity of the cloth, the amount of glass batch fed in each batch is the same, and the feeding of the next batch is started after the last batch is completed and the moving cloth stage 301 has stopped at the designated position.
However, continuous feeding of glass batch materials in the same batch does not mean that the control mechanism 200 continuously receives an incoming material signal, in order to prevent the interruption of the temporary incoming material signal which occurs occasionally during feeding and distribution of glass batch materials in the same batch from interfering with normal materials, the control mechanism 200 of the present application determines that the feeding is terminated after a fifth preset time is interrupted by the received incoming material signal, and after determining that the feeding is terminated, the control mechanism 200 sends a command to stop the distribution to the moving distribution table 301, and the fifth preset time may be set between 1 second and 5 seconds.
In order to prevent the material piling and other phenomena caused by the insufficient interval time between the feeding of the glass batch materials of two adjacent batches, the control mechanism 200 receives the material-feeding signal interruption, and when the material-feeding signal is received again while the movable material-distributing platform 301 is not stopped at the second end of the track 303, the movable material-distributing platform 301 is controlled to continue to execute the steps before the material-feeding signal interruption. That is, when the control means 200 determines that the feeding is terminated but the movable distributing station 301 has not stopped to the final position, if the control means 200 receives a new feeding signal, the control means 200 controls the movable distributing station 301 to continue executing the step before the interruption of the feeding signal.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
