Description

Background Art

[0002] In the process of tile production, power outages are often involved, especially in some remote areas. In the case of a power outage or even a flash outage of the power grid, some electrical operating systems will be interrupted, and the entire system needs to be reset after a call to resume production. This process is a very time-consuming and labor-intensive process in the entire ceramic production line. Each device must be manually reset and started, which poses a challenge to the efficiency of resumption of production. For servo motors, data loss and inaccurate position information will occur after a power outage. The battery will often age, and the communication will be disturbed, which also affects the authenticity and accuracy of the data. Therefore, when the power supply is restored after a power outage, the existing technology has the problem of excessive human intervention, resulting in high labor costs and insufficient intelligence.

[0024] It should be noted that the "multiple" mentioned in this article refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0025] The hardware structure of the multi-roller ceramic hoist system of this application is introduced in detail below: First, refer to Figure 1 As shown, the multi-roller ceramic elevator system includes a controller, a servo motor 1, a roller mechanism 2, a support frame 3, a guide rail 4 and a preset reset point 5, wherein the controller can be specifically a PLC (Programmable Logic Controller), the PLC is used to control the servo motor 1, the preset reset point 5 is generally set at the lower half of the guide rail 4, and the position of the reset point 5 can be set as needed, that is, the height of the reset point 5 can be set arbitrarily.

[0026] The servo motor 1 is arranged on the support frame 3, and guide rails 4 are arranged on both sides of the support frame 3. The two ends of the roller table mechanism 2 are respectively arranged in the guide rails 4, and the reset point 5 is arranged on the guide rails 4. The roller table mechanism 2 includes three roller tables 21, which are arranged in sequence and spaced apart and are all arranged on the guide rails 4. The ceramics to be lifted are placed on the left side of the support frame 3. By placing the ceramics on the roller table 21, the servo motor 1 is used to pull and lift them. After lifting them to the target height (the target height corresponds to the input position of the next production line equipment), they automatically flow to the next production line equipment.

[0027] The multi-roller ceramic elevator system also includes three transmission motors 8, each transmission motor 8 corresponds to a roller table 21, and the transmission motor 8 is used to enable the ceramic placed on the roller table 21 to flow to the next production line equipment. The present application mainly controls the roller table 21 to perform up and down traction movement through the servo motor 1, and controls the ceramic on the roller table 21 to flow from left to right through the transmission motor 8.

[0028] The multi-roller ceramic lifting machine system also includes a preset lower limit point 6 and a preset upper limit point 7, both of which are arranged on the guide rail 4, and the preset lower limit point 6 is arranged below the reset point 5, and the preset upper limit point 7 is arranged above the reset point 5. By setting the preset upper limit point 7, it is possible to prevent the position of the roller table 21 from being pulled too high so that the ceramic placed on the roller table 21 collides with the support frame 3, that is, the multi-roller ceramic lifting system, causing damage to the equipment. Similarly, by setting the lower limit point 6, it is possible to prevent the position of the roller table 21 from being pulled too low so that the bottom of the roller table 21 collides with the support frame 3, that is, the multi-roller ceramic lifting system, causing damage to the equipment.

[0029] Under normal circumstances, the PLC sends a target working instruction, that is, a corresponding pulse signal, to the servo motor 1, and the servo motor 1 pulls the rollers 21 of the three transmission motors 8 to move up and down; Under normal circumstances, servo motor 1 moves in an orderly manner under the accurate position data of PLC; when the power grid is out of power (including flash stop), servo motor 1 stops by inertia braking. When the power is restored, all the position data in the PLC will be lost and instantly become an arbitrary position data. Obviously, this data is not the correct position data. At the same time, due to the inertia of movement, servo motor 1 will also move a certain distance under the action of inertial stop, and all the position data that has slid by inertial stop will be lost. At this time, the origin information reflected by servo motor 1 in PLC will also be deleted. If any of the above factors is incorrect or lost, servo motor 1 will have to be reset to start the position control mode and run the action correctly. If there is no automatic tracking and restoration system, this operation will require manual reset.

[0030] The implementation details of the technical solution of the embodiment of the present application are described in detail below: According to one aspect of an embodiment of the present application, a control method for a multi-roller ceramic lifting system is provided. Figure 2 This is a flow chart of a control method of a multi-roller ceramic lifting system according to an embodiment of the present application. The method is executed in the controller. The method includes at least steps S1 to S3, which are described in detail as follows: In step S1, under a preset power state, a target reset instruction is sent to the servo motor so that the servo motor pulls the roller table mechanism to move toward the reset point, and first position data sent by the servo motor is received. The first position data is sent by the servo motor before the servo motor pulls the roller table mechanism.

[0031] Specifically, the preset power state refers to the moment when the power supply of the multi-roller ceramic hoist system is restored after being cut off, that is, the state of restoring power after a power outage. The target reset instruction is issued by the PLC, that is, the controller described in this application. After receiving the target reset instruction, the servo motor will first send its own servo data D1 (that is, the first position data described in this application) to the PLC before the roller table mechanism performs traction movement. The PLC will convert the format of the first position data and store it (that is, the first position data converted into the first position memory data of the second preset format described in this application). The first position memory data is recorded as D200, and the second preset format refers to the storage format corresponding to the PLC.

[0032] In one embodiment of the present application, the first position data is obtained by the following steps: According to the target reset instruction, any one of the three roller stages is selected as a target roller stage, and any position point of the target roller stage is selected as a target point position; After the servo motor receives the target reset instruction and before the servo motor pulls the roller table mechanism to move toward the reset point, the servo motor generates the first position data and sends the first position data to the controller.

[0033] Specifically, one of the three roller stages can be set as the target roller stage on the PLC control panel, and any position point of the target roller stage can be selected as the target point. In the embodiment of the present application, the roller stage at the bottom of the three roller stages can be selected as the target roller stage, and the position of the induction block set on the target roller stage can be selected as the target point. In this way, when the target point coincides with the reset point, the induction block and the sensor on the reset point sense each other, so that the PLC can know that the entire roller stage mechanism has reached the reset point.

[0034] In step S2, second position data of the roller stage mechanism when it reaches the reset point sent by the servo motor is received, wherein the second position data is obtained by the following steps: In the process that the servo motor pulls the three roller tables to move toward the reset point according to the target reset instruction, when the target point coincides with the reset point, the servo motor generates the second position data.

[0035] Specifically, the PLC will send pulse data corresponding to the target reset instruction to the servo motor. The servo motor can also be represented by SM1, so that SM1 pulls the three roller tables to move to the reset point according to the target reset instruction. When the target point coincides with the reset point, the sensor block and the sensor on the reset point sense each other. The PLC can thus know that the entire roller table mechanism has reached the reset point. At this time, the second position data of SM1 is recorded, and the second position data is represented by D2.

[0036] In step S3, the target position data of the servo motor is determined according to the first position data and the second position data, and the target position data is sent to the servo motor, so that the servo motor generates corresponding target pulse data according to the target position data and pulls the roller table mechanism to move to the original position before the preset power state according to the target pulse data.

[0037] The first position data and the second position data are both position data in a first preset format, and determining the target position data of the servo motor according to the first position data and the second position data includes: converting the first position data into first position memory data in a second preset format; converting the second position data into second position memory data in the second preset format; Subtracting the first position memory data from the second position memory data to obtain position difference data, wherein the position difference data is the position memory data in the second preset format; The position difference data is converted into the target position data in the first preset format, so that the servo motor generates the target pulse data according to the target position data to perform traction motion on the three roller tables.

[0038] Specifically, the first position data and the second position data are both position data in a first preset format. The first preset format corresponds to the format corresponding to the servo motor, that is, the first position data D1 and the second position data D2. The second preset format corresponds to the format that can be stored and recognized by the PLC, that is, the first position memory data. The first position memory data is represented by D200, and the second position memory data is represented by D202.

[0039] The servo motor pulls the three rollers downward according to the target reset instruction, that is, close to the reset point ( Figure 1 The label 5 in the figure makes a recovery motion. Before the motion, the data of servo SM1 is recorded as D1 and stored in the PLC memory D200 (long byte, DM area with power-off retention function). Under the traction of servo motor 1, the roller table continues to move downward toward the reset point 5. At the same time, the position data of servo motor 1 changes in an orderly manner. When the sensing block of the roller table (i.e., the location of the target point) touches the reset point, the data of SM1 is recorded as D2 (i.e., the second position data of the present application) and stored in the PLC memory storage D202. After the D2 data is transmitted, the servo motor completes the reset work, and the position data becomes 0. At the same time, the servo motor records the reset point information. At this time, the position control mode can be performed (the servo motor can be pulse-controlled in the position control mode, so that the servo motor can pull the roller table mechanism to move to the specified position).

[0040] The data difference between D2 and D1 is the position data between the position of the roller table before the power outage and the reset point (i.e. the position difference data described in this application). By subtracting the data of D202 and D200, a position data D3 (i.e. the position difference data described in this application) can be obtained, and the D3 data is stored in the memory storage D204 (i.e. the target position data described in this application).

[0041] The data of D204 is transmitted to the pulse data of the position control to generate the target pulse data. The servo motor automatically returns to the position before the power failure (i.e. the original position) through the corresponding target pulse data in the position control mode. The entire process of automatic resetting and restoring the original position is an automatic tracking and restoration process carried out after power supply is restored and safety hazards are automatically eliminated. This process does not require human intervention. The multi-roller ceramic lifting system can independently judge and execute, which plays an important role in quickly resuming production after the power grid is restored.

[0042] In one embodiment of the present application, the multi-roller ceramic hoist system further includes a preset lower limit point and a preset upper limit point, both of which are arranged on the guide rail, and the preset lower limit point is arranged below the reset point, and the preset upper limit point is arranged above the reset point; after the roller mechanism moves to the original position, the method further includes: Sending a target working instruction to the servo motor so that the servo motor performs a pulling motion on one or more roller tables according to the target working instruction; During the traction movement of one or more roller platforms, if it is detected that the top of any roller platform reaches the preset upper limit point or the bottom of any roller platform reaches the preset lower limit point, a warning instruction is generated; The early warning instruction is sent to a preset terminal device so that the terminal device issues an alarm according to the early warning instruction.

[0043] Specifically, by setting the preset lower limit point ( Figure 1 6) and the preset upper limit point ( Figure 1 7) When the top of any roller table reaches the preset upper limit point or the bottom of any roller table reaches the preset lower limit point under normal working conditions of the roller table mechanism, an early warning instruction is generated, so that the preset terminal device can alarm according to the early warning instruction. The preset terminal device can be a mobile phone, tablet or other device, so that the staff can promptly perform subsequent processing such as shutdown and repair according to the alarm information.

[0044] In one embodiment of the present application, the target work instruction is obtained by the following steps: Acquire target ceramic data to be upgraded, and divide the target ceramic data into three equal parts of ceramic data; Determine the target movement amount required for each of the roller tables according to each of the equal ceramic data; Generate target motion data of the servo motor according to each target motion amount; The target working instruction is generated according to the target motion data, so that the servo motor performs reciprocating traction motion according to the target motion data corresponding to the target working instruction, so as to lift each ceramic corresponding to the target ceramic data.

[0045] Specifically, the target ceramic data to be lifted refers to the individual ceramics that need to be lifted, and three transmission motors need to be pulled to lift and transport these ceramics horizontally. Since there are three roller tables, these ceramics can be divided into three equal parts of three equal amounts of ceramic data according to the number of ceramics, and then the target motion required for each roller table to complete the lifting and transportation of these equal amounts of ceramic data can be calculated based on these equal amounts of ceramic data. That is, according to these target motion amounts, the roller tables can be controlled to perform orderly and repeated lifting motions, that is, the target motion data of the servo motor is generated, and then the target working instruction is generated according to the target motion data, so that the servo motor performs reciprocating traction motion according to the target motion data corresponding to the target working instruction, so as to lift each ceramic corresponding to the target ceramic data.

[0046] To sum up, when the power supply of the multi-roller ceramic elevator system is restored after being cut off, that is, in the preset power state, the controller automatically sends a target reset instruction to the servo motor. Then, before the servo motor receives the target reset instruction and performs traction movement, it will receive the first position data sent by the servo motor, that is, the initial data corresponding to the time when the roller mechanism is not moving.

[0047] When the roller table mechanism is moving, when the roller table mechanism moves to the reset point, the second position data sent by the servo motor is recorded at this time, then the movement amount of the roller table mechanism controlled by the servo motor in this process can be determined according to the first position data and the second position data, and the target position data is determined accordingly. By sending the target position data to the servo motor, the servo motor generates corresponding target pulse data according to the target position data and pulls the roller table mechanism to the original position before the preset power state according to the target pulse data, so that the roller table mechanism can be pulled by the servo motor when it reaches the reset point, and automatically restored to the original position before the power outage, that is, before the preset power state, that is, the entire multi-roller ceramic hoist system can automatically reset after the power supply is restored, and return to the original position before the power outage, without manual intervention throughout the process, which greatly reduces the labor cost and improves the intelligence of the multi-roller ceramic hoist system, thereby improving the production efficiency of the ceramic production line and ensuring the orderly operation of the production line.

The sending unit 301 is used to send a target reset instruction to the servo motor under a preset power state so that the servo motor pulls the roller table mechanism to move toward the reset point, and receive first position data sent by the servo motor, where the first position data is sent by the servo motor before the servo motor pulls the roller table mechanism; A receiving unit 302 is used to receive second position data sent by the servo motor when the roller table mechanism reaches the reset point; A determination unit 303 is used to determine the target position data of the servo motor according to the first position data and the second position data, and send the target position data to the servo motor, so that the servo motor generates corresponding target pulse data according to the target position data and pulls the roller table mechanism to move to the original position before the preset power state according to the target pulse data; The preset power state is the moment when the power supply of the multi-roller ceramic hoist system is restored after being cut off.
